    Little, Susan J

    Diagnosis of acute HIV infection is important for accurate estimation of HIV incidence, identifying persons who are unaware of their HIV infection, and offering immediate treatment and risk-reduction strategies. The higher viral loads associated with acute HIV infection are associated with an increased risk of transmission. Current treatment recommendations are the same for acute and established infections. Studies of acute HIV infection indicate that initiation of antiretroviral therapy during this period may allow greater recovery of CD4+ T-cell count and function and may result in a smaller latent viral reservoir and a skewing of infection away from central memory CD4+ T cells toward shorter-lived transitional memory CD4+ T cells. This article summarizes a presentation by Susan J. Little, MD, at the IAS-USA continuing education program, Improving the Management of HIV Disease, held in Los Angeles, California, in April 2015.

    There are numerous case reports on psychoses in AIDS patients and, although more seldom, also in HIV-positive patients in early stages of infection; however, systematic investigations on the frequency, e.g., relevant for the indication of an HIV test in psychiatric patients, are missing. For this study, 1046 HIV-positive patients were examined regarding psychoses. A total of 301 patients (28.8%) were HIV-positive but asymptomatic, and 380 patients (36.2%) had the lymphadenopathy syndrome. One hundred thirty-two patients (12.6%) suffered from an AIDS-related complex and 233 patients (22.3%) from AIDS. Of these 1046 patients, only 9 (0.9%) suffered from psychoses. One patient with a paranoid-hallucinatory syndrome was asymptomatic; one in the lymphadenopathy syndrome was manic. The other 7 patients were all in late stages of the infection. A causal relationship between HIV infection and psychosis and probable in only 3 patients. These data do not indicate a markedly elevated prevalence of psychosis in HIV-positive or AIDS patients.

    Introduction: Human immunodeficiency virus (HIV) infection has become a global pandemic. Persistent generalized lymphadenopathy (PGL) is very common manifestation of HIV infection. Moreover, different opportunistic infections such as tuberculosis (TB) and malignancies may present with lymphadenopathy. Mycobacterium avium complex (MAC) infection is most common with cluster of differentiation (CD)4+ count ≤50 cells/μL. Fine-needle aspiration cytology (FNAC) offers a simple and effective modality for obtaining a representative sample of the material from lymph nodes, permitting cytological evaluation and other investigations. Aims and Objectives: The aim of this study is to find out the different etiologies of lymphadenopathy in HIV-infected patients and to establish a possible correlation with CD4+ count. Materials and Methods: A total of 100 HIV-infected patients having significant (>1 cm) extrainguinal lymphadenopathy were studied in 1 year at the Department of Pathology by FNAC and the stains used were Leishman–Giemsa, Ziehl–Neelsen (ZN), Papanicoloau, and Gram stains. For tubercular culture, Löwenstein–Jensen (LJ) medium was used. CD4+count was done by flow cytometer. Result: The present study revealed four types of cytomorphological variants in lymphadenopathy cases by FNAC, which include: Reactive hyperplasia and caseation necrosis; caseation necrosis and ill-formed granuloma; well-formed granuloma without any necrosis; and non-Hodgkin lymphoma (NHL). The highest acid-fast bacilli (AFB) positivity was among the patients showing caseation necrosis. Tubercular culture in LJ media turned out as a more sensitive method for diagnosis than routine ZN staining. The 2 cases that showed well-formed epithelioid granuloma without any necrosis turned out to be histoplasmosis and cryptococcosis, respectively. In this study, we found 2 cases of NHL. The study also revealed that caseation necrosis and AFB positivity along with opportunistic infections increases with

    Thanks to a worldwide collaborative effort among health care providers, academia, governments, and industry, our knowledge base about infection caused by the human immunodeficiency virus (HIV) has expanded exponentially. During the past 2 decades, we have learned about its pathogenesis, virology, immunology, epidemiology and treatment. In the developed world, the approach to persons with HIV disease has evolved from palliative disease care to use of a chronic disease model, where survival is measured by decades, not months or years. More and more, clinical decision-making for HIV-infected patients is driven by comorbidities, including cardiothoracic disease. Thus, our clinically stable HIV population is increasingly accessing those health care services required by any maturing population, including the usual services of cardiothoracic surgeons. In this article, we review the basic facts of HIV disease, with an emphasis on occupational risks and infection control procedures. PMID:10807435

    Significant survival prolongation in HIV-infected patients due to effective antiretroviral therapy is connected with increasing prevalence of chronic non-infective diseases in this population, among them chronic kidney disease. The pathogenesis of kidney disease in the setting of HIV includes conditions specific for HIV infection: direct effect of the virus, stage of immunodeficiency and drug toxicity. Chronic comorbidities, such as diabetes mellitus, hypertension, and hyperlipidemia, are additional significant risk factors of kidney disease. In HIV-infected individuals some distinct features of these conditions are observed, which are partly related to the virus and antiretroviral therapy. The article summarizes the effect of comorbidities on kidney function in HIV-infected persons. PMID:26671927

    AIDS among persons who inject drugs, first identified in December 1981, has become a global epidemic. Injecting drug use has been reported in 148 countries and HIV infection has been seen among persons who inject drugs in 61 countries. Many locations have experienced outbreaks of HIV infection among persons who inject drugs, under specific conditions that promote very rapid spread of the virus. In response to these HIV outbreaks, specific interventions for persons who inject drugs include needle/syringe exchange programs, medicated-assisted treatment (with methadone or buprenorphine) and antiretroviral therapy. Through a 'combined prevention' approach, these interventions significantly reduced new HIV infections among persons who inject drugs in several locations including New York City, Vancouver and France. The efforts effectively ended the HIV epidemic among persons who inject drugs in those locations. This review examines possible processes through which combined prevention programs may lead to ending HIV epidemics. However, notable outbreaks of HIV among persons who inject drugs have recently occurred in several countries, including in Athens, Greece; Tel-Aviv, Israel; Dublin, Ireland; as well as in Scott County, Indiana, USA. This review also considers different factors that may have led to these outbreaks. We conclude with addressing the remaining challenges for reducing HIV infection among persons who inject drugs.

    Background HIV infection is associated with dyslipidemia and increased risk for cardiovascular events. Few studies have described lipid status in medically-underserved, HIV-infected ethnic minorities, a group that is characterized by health disparities. Objective The objective was to characterize the lipid profile of a medically-underserved, largely ethnic minority sample of HIV-infected persons using standard lipid panels and nuclear magnetic resonance (NMR) -derived lipoprotein particle profiles. Methods Participants were recruited from a randomized controlled trial of a dietary supplement to manage HIV-related dyslipidemia (N=132). At the initial screening visit, sociodemographic, clinical, and behavioral data were collected, and fasting peripheral venous blood specimens were obtained and lipid status was analyzed using the standard lipid panel and the NMR-derived lipoprotein particle profile. Results Using NMR-derived LDL particle cutoffs, a higher percentage of participants was outside the target range (50%) than when standard LDL cholesterol NCEP cutoffs were used (24%). Antiretroviral therapy, especially protease inhibitor-containing regimens, was associated with higher LDL particle concentration. Conclusion Substantial numbers of medically-underserved, asymptomatic HIV-infected minorities may be at increased risk for CHD based on NMR-derived lipoprotein values. PMID:20161509

    The etiology of genital ulcer disease (GUD) and the relationship between GUD and HIV infection were investigated in 302 patients presenting to a sexually transmitted disease clinic in Pune, India, in a 3-month period in 1994. Swabs of each genital ulcer were tested for herpes simplex virus (HSV) antigen by enzyme immunoassay and processed in a multiplex polymerase chain reaction (M-PCR) assay for simultaneous detection of HSV, Treponema pallidum, and Haemophilus ducreyi. The seroprevalence of HIV in this series was 22.2%. Clinical diagnosis of GUD was undermined when HIV infection was present. The etiology of GUD according to M-PCR was HSV in 26%, chancroid in 23%, primary syphilis in 10%, and multiple infections in 7%; no etiology could be identified in the remaining 34% of cases. Attempts to differentiate the etiology of GUD based solely on clinical grounds resulted in many inaccurate diagnoses. Chancroid was the most common clinical diagnosis (40%), followed by HSV (24%), syphilis (20%), and multiple infections (3%). HIV seroprevalence was significantly higher in patients with HSV compared with other etiologies (odds ratio, 2.1; 95% confidence interval, 1.2-3.7), presumably as a result of HIV-induced immunosuppression and consequent HSV reactivation. Until rapid, inexpensive, and sensitive assays become available, syndromic treatment with antibiotics should be provided to patients with GUD in order to reduce the risk of acquiring HIV infection.

    Between June 1996-September 1997 and December 1998-December 1999, two surveys using an anonymous questionnaire were carried out in Europe among persons living with HIV infection. The questionnaire included questions on use of antiretrovirals, complementary or alternative medicines. Vitamins/minerals were taken by 528 (58%) of the 1996-97 participants, compared to 326 (63%) of the 1998-99 participants (P =0.06). Homeopathy was taken by respectively 176 (21%) and 55 (14%) (P =0.003) participants and herbal products respectively by 213 (25%) and 77 (20%) (P =0.06). In multiple regression analysis a longer time since HIV diagnosis, having a higher education level and having a lower CD(+) lymphocyte count were associated with the use of homeopathy. A longer time since HIV diagnosis and a more advanced stage of the disease were associated with the use of herbal products. The study shows that despite the availability of highly active antiretroviral therapy many people with HIV infection still take complementary and alternative medicine. PMID:14596770

    Molecular characterization of Enterocytozoon bieneusi has led to better understanding of microsporidiosis transmission in humans. This study aimed to detect and genotype E. bieneusi in human immunodeficiency virus (HIV)-infected persons. Stool specimens were collected from 463 HIV-infected patients and analyzed for E. bieneusi by polymerase chain reaction (PCR) and DNA sequence analysis of the internal transcribed spacer. E. bieneusi was detected in 77 HIV patients. CD4 cell counts < 200 cells/μL was associated with E. bieneusi infection (P = 0.09). E. bieneusi was significantly associated with weight loss (P < 0.0001), diarrhea (P = 0.006), fever (P < 0.0001), not being married (P < 0.0001), and flush type of toilet (P = 0.0007). Six known genotypes of D, A, IV, CAF2, EbpA, and Peru 8 in 31, 22, 14, 2, 1, and 1 patients, respectively, five novel genotypes of E. bieneusi, and one infection with mixed genotypes were observed in this study. Three of the novel genotypes were genetically distant to the genotypes commonly found in humans. PMID:22403314

    Background HIV infected individuals have heightened cancer risk. With the advent of HAART, the frequency of some AIDS defining cancers (ADC) has decreased while certain non-AIDS defining cancers (NADC) are becoming more frequent. Cancers among HIV-infected individuals in Latin American and the Caribbean have not yet been carefully studied. Methods Cancer cases among the Caribbean, Central and South American network for HIV Research (CCASAnet) cohort were identified reviewing clinical records and preexisting databases. Results There were 406 cancers reported: 331 ADC (224 Kaposi´s sarcomas and 98 non Hodgkin lymphomas). Most frequent NADC (n=75) were Hodgkin lymphoma and skin cancers. Seventy-three percent of NADC and 45% of ADC were diagnosed >1 year after HIV diagnosis. 56% of ADC occurred before HAART start. Median time from HAART start until cancer diagnosis was 2.5 years for NADC and 0.5 years for ADC (p=<0.001). Within 3372 HAART starters, 158 were diagnosed with 165 cancers (82.4% ADC); 85 cases were previous to or concomitant with HAART initiation. Incidence of cancer after HAART initiation in 8080 person-years of follow-up was 7.2 per 1000 person-years (95%CI= 5.5–9.3) for ADC and 2.7 (95%CI= 1.8–4.1) for NADC; incidence was higher in the first two months, particularly for ADC (47.6). A pre-HAART ADC was a predictor of mortality after adjusting for age, sex, and CD4 at HAART initiation. Conclusions ADC were the most frequent cancers in this region and were often diagnosed close to HIV diagnosis and HAART start. Incidence of cancer was highest around HAART initiation. PMID:21239992

    Abstract Immigrants to the United States are more likely to be diagnosed with human immunodeficiency virus (HIV) infection compared with native-born persons. Navigating access to healthcare in the United States can be challenging for foreign-born persons, and HIV treatment outcomes may be suboptimal for these persons. We compared characteristics of and assessed disparities in clinical outcomes of foreign-born persons in care for HIV in the United States. The Medical Monitoring Project is a complex sample, cross-sectional survey designed to be nationally representative of HIV-infected adults receiving medical care in the United States. Using data from 2009, 2010, and 2011, we conducted descriptive analyses and multivariable logistic regression to assess associations between foreign-born status and antiretroviral therapy (ART) prescription, and between foreign-born status and viral suppression. In all, 13.4% of HIV-infected persons were self-identified as foreign-born; the most common regions of birth were Central America and Mexico (45.4%) and the Caribbean (16.0%). Nearly 90% of foreign-born persons were diagnosed with HIV after entry into the United States. Compared with US-born persons, foreign-born persons were more likely to be younger, Hispanic, less educated, and uninsured. The prevalence of ART prescription (prevalence ratio 1.00; 95% confidence interval 0.98–1.02) was not significantly different between foreign-born and US-born persons. A higher percentage of foreign-born persons achieved viral suppression compared with US-born persons (prevalence ratio 1.05; 95% confidence interval 1.00–1.09). No major disparities in ART prescription and viral suppression were found between foreign-born and US-born HIV-infected persons receiving medical care, despite higher percentages being uninsured.

    The organizational technologies of increasing effectiveness ofdispensarization monitoring of HIV-infected persons are to targeted to development in patients commitment to get medical care. The cohort monitoring of registered patients receiving anti-retrovirus therapy permitted to evaluate effectiveness of organizational model of multi-professional team developing commitment ofpatients to anti-retrovirus therapy in conditions of center ofprevention and struggle with AIDS and infectious diseases. The criteria ofeffectiveness offunctioning ofmulti-professional team are developed and implemented The list of criteria include percentage of patients in cohort with optimal commitment (not lower than 95% of applied dosage of anti-retrovirus pharmaceuticals at 12th, 24th, 36th, 48th and 60th month), percentage ofpatients with achieved effect of anti-retrovirus therapy, percentage of patients proceeding anti-retrovirus therapy. The multi-professional team implemented motivational techniques of behavior alteration and patient-oriented care. The main strategy of development of of commitment to anti-retrovirus therapy under HIV-infection is determined as management of resources and risks capable decreasing commitment to dispensarization monitoring. The analysis of problems permitted to structure them in risks of commitment failure: medical (13.7%), medical biological under using psychoactive substances (43.1%), psychological (27.7%), social (15.5%). This listing determined the profile of specialists of multi-professional team. The ranking of risks lead out to the first ranking place medical risks, including diagnosed tuberculosis, combination of secondary and concomitant diseases inpatient, number of intaking pills more than 7 per day. The second ranking place took medical biological risks in users of psychoactive substances. Up to 60th month the anti-retrovirus therapy was proceeded by 61.5% of users of psychoactive substances with optimal commitment in 60%. The implementation

We examine racial/ethnic disparities in New York City among persons who inject drugs after implementation of the New York City Condom Social Marketing Program in 2007. Quantitative interviews and HIV testing were conducted among persons who inject drugs entering Mount Sinai Beth Israel drug treatment (2007-2014). 703 persons who inject drugs who began injecting after implementation of large-scale syringe exchange were included in the analyses. Factors independently associated with being HIV seropositive were identified and a published model was used to estimate HIV infections due to sexual transmission. Overall HIV prevalence was 4%; Whites 1%, African-Americans 17%, and Hispanics 4%. Adjusted odds ratios were 21.0 (95% CI 5.7, 77.5) for African-Americans to Whites and 4.5 (95% CI 1.3, 16.3) for Hispanics to Whites. There was an overall significant trend towards reduced HIV prevalence over time (adjusted odd ratio = 0.7 per year, 95% confidence interval (0.6-0.8). An estimated 75% or more of the HIV infections were due to sexual transmission. Racial/ethnic disparities among persons who inject drugs were not significantly different from previous disparities. Reducing these persistent disparities may require new interventions (treatment as prevention, pre-exposure prophylaxis) for all racial/ethnic groups. PMID:25965957

    This study sought to determine the effects of HIV-associated neurocognitive disorders (HAND) on health literacy, which encompasses the ability to access, understand, appraise, and apply health-related information. Participants included 56 HIV seropositive individuals, 24 of whom met Frascati criteria for HAND, and 24 seronegative subjects who were comparable on age, education, ethnicity, and oral word reading. Each participant was administered a brief battery of well-validated measures of health literacy, including the Expanded Numeracy Scale (ENS), Newest Vital Sign (NVS), Rapid Estimate of Adult Literacy in Medicine (REALM), and Brief Health Literacy Screen (BHLS). Results revealed significant omnibus differences on the ENS and NVS, which were driven by poorer performance in the HAND group. There were no significant differences on the REALM or the BHLS by HAND status. Among individuals with HAND, lower scores on the NVS were associated with greater severity of neurocognitive dysfunction (e.g., working memory and verbal fluency) and self-reported dependence in activities of daily living. These preliminary findings suggest that HAND hinders both fundamental (i.e., basic knowledge, such as numeracy) and critical (i.e., comprehension and application of healthcare information) health literacy capacities, and therefore may be an important factor in the prevalence of health illiteracy. Health literacy-focused intervention may play an important role in the treatment and health trajectories among persons living with HIV infection. PMID:25008384

    The Therapeutic Community (TC) for HIV-infected persons is neither a hospital nor a confinement for people with HIV. Actually it is a family of friends who are in the same boat and a place of education to teach them about AIDS and relevant subjects necessary for their life in the future, and to help establish new values and life styles for them using TC tools which are adapted from the DAYTOP TC in U.S.A. The purpose was not only to build the residents, but also to encourage them to do their part in contributing to build up a better and safer society that will help to save the lives of others from AIDS. Correct knowledge in AIDS, together with the quality of honesty, responsibility and other basic attitudes that the residents acquire through the program will enable them to become a creative force in the prevention and control of AIDS. The author would say that words alone will not describe the whole TC. It requires self experience through the program in order to learn TC and understand it. PMID:8576664

    Objective The incidence of certain non-AIDS-defining cancers (NADC) in HIV patients has been reported to have increased in the combination antiretroviral therapy (ART) era. Studies are needed to directly evaluate the effect of ART use on cancer risk. Design We followed 12,872 HIV+ Kaiser Permanente members whose complete ART history was known for incident cancers between 1996-2008. Methods Cancers, identified from SEER-based cancer registries, were grouped as AIDS-defining cancers (ADC), infection-related NADC or infection-unrelated NADC. We also evaluated the most common individual cancer types. Rate ratios (RR) for ART use (yes/no) and cumulative duration of any ART, PI and NNRTI therapy were obtained from Poisson models adjusting for demographics, pre-treatment or recent CD4 count and HIV RNA levels, years known HIV-infected, prior antiretroviral use, HIV risk, smoking, alcohol/drug abuse, overweight/obesity, and calendar year. Results The cohort experienced 32,368 person-yrs (py) of ART, 21,249 py of PI therapy, and 15,643 py of NNRTI therapy. The mean follow-up duration was 4.5 years. ADC rates decrease with increased duration of ART use [RR/year=0.61, 95% CI (0.56-0.66)]; the effect was similar by therapy class. ART, PI or NNRTI therapy duration was not associated with infection-related or infection-unrelated NADC [RR/year ART=1.00 (0.91-1.11) and 0.96 (0.90-1.01), respectively], except a higher anal cancer risk with longer PI therapy [RR/year=1.16 (1.02-1.31)]. Conclusions No therapy class-specific effect was found for ADC. ART exposure was generally not associated with NADC risk, except for long term use of PI, which might be associated with increased anal cancer risk. PMID:22951631

    This is the first Romanian investigation of oral candidosis in patients suffering of HIV-infection or type 1 diabetes mellitus (T1DM). Candida albicans was the dominant species in both types of isolates: n = 14 (46.7%) in T1DM, n = 60 (69.8%) in HIV. The most frequent non-albicans Candida spp. were Candida kefyr (n = 6; 20%) in T1DM and Candida dubliniensis (n = 8; 9.3%) in HIV. Resistance to fluconazole was detected only in the HIV non-albicans Candida group (n = 8; 9.3%). All isolates were susceptible to VOR. The experimental drug MXP had MIC values equal or close to the ones of VOR. Echinocandin resistance was more frequent than azole resistance. PMID:27282005

    Studies have consistently found high levels of HIV infection among male-to-female (MTF) transgender people, particularly MTF sex workers. Due to lack of empirical data, HIV/AIDS risk among female-to-male (FTM) transgender people, however, is not well understood. This study analysed data from two needs assessment surveys to compare risk for HIV infection between 122 MTF and 62 FTM transgender people. Results show that there was a significant gender difference in HIV risk among the survey respondents. Compared to MTFs, FTMs were significantly less likely to have used protection the last time they had sex and significantly more likely to have engaged in recent high risk sexual activity. The gender difference existed even after controlling for demographic variables, AIDS knowledge, perceived AIDS knowledge, perceived effectiveness of condom usage, perceived susceptibility to AIDS and self-esteem. Findings from this study suggest that a thorough examination of HIV risk factors among FTMs is necessary. PMID:15763714

    Apathy is a relatively common psychiatric syndrome in HIV infection, but little is known about its neural correlates. In the present study, we examined the associations between apathy and diffusion tensor imaging (DTI) indices in key frontal white matter regions in the thalamocorticostriatal circuit that has been implicated in the expression of apathy. Nineteen participants with HIV infection and 19 demographically comparable seronegative comparison subjects completed the Apathy subscale of the Frontal Systems Behavioral Scale as a part of a comprehensive neuropsychiatric research evaluation. When compared to the seronegative participants, the HIV+ group had significantly more frontal white matter abnormalities. Within HIV+ persons, and as predicted, higher ratings of apathy were associated with greater white matter alterations in the anterior corona radiata, genu, and orbital medial prefrontal cortex. The associations between white matter alterations and apathy were independent of depression and were stronger among participants with lower current CD4 counts. All told, these findings indicate that apathy is independently associated with white matter abnormalities in anterior, medial brain regions in persons infected with HIV, particularly in the setting of lower current immune functioning, which may have implications for antiretroviral therapy.

    Background Pain is highly prevalent among persons with HIV. Alcohol may be used to “self-medicate” pain. This study examined the association between pain and risky alcohol use over time in a cohort of HIV-infected Russian drinkers. Methods This secondary analysis utilized longitudinal data from a randomized trial of a behavioral intervention. Subjects included HIV-infected adults who reported past 6-month risky drinking and unprotected sex and were recruited from HIV and addiction treatment sites in St. Petersburg, Russia. The main independent variable was pain that at least moderately interfered with daily living. The primary outcome was past month risky drinking amounts based on NIAAA guidelines. General estimating equations (GEE) logistic regression models were used to calculate odds ratios and 95% confidence intervals for the association between pain and risky drinking over time (i.e., baseline, 6- and 12-months), adjusting for potential confounders. Results Baseline characteristics of participants (n=699) were mean age of 30 (SD±5) years, 41% female, and 22% < 9th grade education. Nearly one quarter (24%) had a CD4 cell count <200 cells/μ/l, and only 17% were on antiretroviral therapy. Nearly half (46%) reported at least moderate pain interference in the past month and 81% were drinking risky amounts. In adjusted longitudinal GEE models, pain was significantly associated with greater odds of reporting past month risky drinking (AOR=1.34, 95% CI: 1.05-1.71, p-value=0.02). Conclusions Among a cohort of HIV-infected Russian drinkers, pain that at least moderately interfered with daily living was associated with higher odds of reporting risky drinking amounts over time.

    Progressive multifocal encephalopathy (PML) caused by JC virus was frequently encountered in AIDS patients before combination antiretroviral therapy (cART). Incidence decreased and the outcome improved with cART. The immune reconstitution with cART is beneficial for HIV-infected patients and is an effective treatment for PML. However, when it is excessive an inflammatory response immune syndrome might occur with deterioration of PML. So far, no specific therapy has proven efficacious in small clinical trials in spite of some optimistic case reports. Combination of drugs targeted at different stages of JC virus life cycle seems to have a better effect. Passive and active immune therapies, immune competence "boosters" appear promising. New future approaches such as gene editing are not far away. PMID:26655489

    Immigrants to the United States are more likely to be diagnosed with human immunodeficiency virus (HIV) infection compared with native-born persons. Navigating access to healthcare in the United States can be challenging for foreign-born persons, and HIV treatment outcomes may be suboptimal for these persons. We compared characteristics of and assessed disparities in clinical outcomes of foreign-born persons in care for HIV in the United States. The Medical Monitoring Project is a complex sample, cross-sectional survey designed to be nationally representative of HIV-infected adults receiving medical care in the United States. Using data from 2009, 2010, and 2011, we conducted descriptive analyses and multivariable logistic regression to assess associations between foreign-born status and antiretroviral therapy (ART) prescription, and between foreign-born status and viral suppression. In all, 13.4% of HIV-infected persons were self-identified as foreign-born; the most common regions of birth were Central America and Mexico (45.4%) and the Caribbean (16.0%). Nearly 90% of foreign-born persons were diagnosed with HIV after entry into the United States. Compared with US-born persons, foreign-born persons were more likely to be younger, Hispanic, less educated, and uninsured. The prevalence of ART prescription (prevalence ratio 1.00; 95% confidence interval 0.98-1.02) was not significantly different between foreign-born and US-born persons. A higher percentage of foreign-born persons achieved viral suppression compared with US-born persons (prevalence ratio 1.05; 95% confidence interval 1.00-1.09). No major disparities in ART prescription and viral suppression were found between foreign-born and US-born HIV-infected persons receiving medical care, despite higher percentages being uninsured.

    Objective Cardiovascular disease risk among persons with HIV is likely multifactorial, thus testing a variety of available noninvasive vascular ultrasound and other surrogate tests may yield differing results. To address this issue, we assessed multiple metabolic and clinical predictors of endothelial function and carotid intima–media thickness in HIV-infected subjects and compared results with HIV-negative controls. Design Prospective, cross-sectional study of 50 HIV-infected, healthy adults on stable highly active antiretroviral therapy matched to 50 HIV-negative controls by age, sex, race, and body mass index. Methods Flow-mediated vasodilation of the brachial artery, carotid intima–media thickness, dual energy X-ray absorptiometry (HIV-infected subjects), and fasting insulin, lipids, and oral glucose tolerance tests were performed. Results were compared between HIV-infected and control groups. Results Fifty percent of subjects were African–American with 34% women. Among HIV-infected, mean CD4 cell count was 547 cells/ µl; 90% had HIV RNA less than 50 copies/ml. There were no significant differences between HIV-infected and control subjects with regard to brachial artery flow-mediated vasodilation or carotid intima–media thickness. In multivariate analyses of the HIV cohort, independent predictors of endothelial dysfunction (lower flow-mediated vasodilation) were increasing insulin resistance, greater alcohol consumption, and higher baseline brachial artery diameter (P < 0.05); predictors of increased carotid intima–media thickness were hypertension, higher trunk/limb fat ratio, and insulin resistance (P < 0.05). Conclusion In this HIV cohort on modern highly active antiretroviral therapy with well controlled HIV, there were no significant differences with regard to preclinical markers of cardiovascular disease. Insulin resistance was a strong predictor of impaired brachial artery flow-mediated vasodilation and increased carotid intima

    Background Enhanced HIV surveillance using demographic, behavioral, and biologic data from national surveys can provide information to evaluate and respond to HIV epidemics efficiently. Methods From October 2012 to February 2013, we conducted a 2-stage cluster sampling survey of persons aged 18 months to 64 years in 9 geographic regions in Kenya. Participants answered questionnaires and provided blood for HIV testing. We estimated HIV prevalence, HIV incidence, described trends in HIV prevalence over the past 5 years, and identified factors associated with HIV infection. This analysis was restricted to persons aged 15–64 years. Results HIV prevalence was 5.6% [95% confidence interval (CI): 4.9 to 6.3] in 2012, a significant decrease from 2007, when HIV prevalence, excluding the North Eastern region, was 7.2% (95% CI: 6.6 to 7.9). HIV incidence was 0.5% (95% CI: 0.2 to 0.9) in 2012. Among women, factors associated with undiagnosed HIV infection included being aged 35–39 years, divorced or separated, from urban residences and Nyanza region, self-perceiving a moderate risk of HIV infection, condom use with the last partner in the previous 12 months, and reporting 4 or more lifetime number of partners. Among men, widowhood, condom use with the last partner in the previous 12 months, and lack of circumcision were associated with undiagnosed HIV infection. Conclusions HIV prevalence has declined in Kenya since 2007. With improved access to treatment, HIV prevalence has become more challenging to interpret without data on new infections and mortality. Correlates of undiagnosed HIV infection provide important information on where to prioritize prevention interventions to reduce transmission of HIV in the broader population. PMID:24445338

    Summary HIV (human immunodeficiency virus) infection may produce no clinical symptoms for 10 years on average. However, after many years of infection most people develop symptoms that indicate progression of the disease. There are no regular characteristic symptoms or early stage, and no logical sequence of AIDS indicator disorders has been observed. People who are not aware of the infection are referred to physicians of various specializations, including otolaryngologists. It is on their knowledge about HIV infections, among other factors, that early diagnosis of the disease depends. Appropriate and quick introduction of anti-retroviral drugs may let a person with HIV live decades longer. PMID:22367140

    This study sought to identify social service needs of HIV-infected persons at the time of release from prison/jail and to describe their case management experiences after release from prison/jail. Sixteen men and women who were infected with HIV, each with a history of incarceration, participated in one of three focus group sessions. Study participants consisted of 11 men and five women. The majority of the participants were African-American (81%), single (50%), and currently unemployed (69%). Qualitative analysis of the focus group transcripts revealed a total of 483 comments regarding a need for social or health services. These comments were further grouped into 13 categories of services or service-related issues that represented the range of the responses. Although participants described positive experiences with specific case managers, their overall evaluation of case management was negative. Identified social services needs and the descriptions of their experiences with case management provides insight as to how case management services can be improved for this population. PMID:16398065

    Metabolic and morphologic abnormalities in persons with HIV remain common contributors to stigma and morbidity. Increased abdominal circumference and visceral adiposity were first recognized in the late 1990s, soon after the advent of effective combination antiretroviral therapy. Visceral adiposity is commonly associated with metabolic abnormalities including low HDL-cholesterol, raised triglycerides, insulin resistance, and hypertension, a constellation of risk factors for cardiovascular disease and diabetes mellitus known as "the metabolic syndrome". Medline and conference abstracts were searched to identify clinical research on factors associated with visceral adiposity and randomized studies of management approaches. Data were critically reviewed by physicians familiar with the field. A range of host and lifestyle factors as well as antiretroviral drug choice were associated with increased visceral adiposity. Management approaches included treatment switching and metformin, both of which have shown benefit for insulin-resistant individuals with isolated fat accumulation. Testosterone supplements may also have benefits in a subset of individuals. Supra-physiological doses of recombinant human growth hormone and the growth hormone releasing hormone analog tesamorelin both significantly and selectively reduce visceral fat over 12-24 weeks; however, the benefits are only maintained if doping is continued. In summary, the prevention and management of visceral adiposity remains a substantial challenge in clinical practice. PMID:20216906

    Although human immunodeficiency virus (HIV) infection is a worldwide problem, its prevalence and pattern vary from country to country. Accordingly, the risk to international travellers of acquiring HIV infection also varies widely in different parts of the world, and depends principally on their behaviour. The risk of sexual acquisition of HIV infection can be virtually eliminated by avoiding penetrative sexual intercourse with intravenous drug users and persons who have had multiple sexual partners (such as prostitutes) or reduced by the use of condoms. The risk of parenteral exposure to HIV can be reduced by avoiding parenteral drug use and behaviour that is likely to lead to injury (with its attendant risk of requiring blood transfusion) and by seeking medical facilities with adequate capabilities to screen blood donors for HIV and to sterilize instruments. HIV screening of international travellers is an ineffective, costly, and impractical public health strategy for limiting the worldwide spread of HIV infection. Travellers infected with HIV require specialized advice regarding health precautions, prophylactic medications, and immunization. PMID:2194689

    The development of new pharmaceutical interventions for persons with human immunodeficiency virus (HIV) infection has resulted in extended survival and a need for valid, reliable and responsive instruments to assess health-related QoL (HRQoL). This paper reviews the reliability and validity of an HRQoL instrument, the AIDS Health Assessment Questionnaire (AIDS-HAQ), among persons participating in an observational database of HIV infection. The AIDS-HAQ includes nine subscales: disability, energy, general health, pain, cognitive functioning, mental health, social functioning, health distress and symptoms. Individuals complete the AIDS-HAQ quarterly. Data are reported for 440 individuals entering the study with early HIV infection. Fifty-nine progressed to symptomatic disease and 109 to AIDS after 1 year. The subscales of the instrument resulted in high internal consistency reliability (range = 0.79-0.88). Concurrent validity data reflected the ability to distinguish between patients with increasing disease severity. In all domains, except cognitive functioning, individuals who progressed to AIDS had significant decrements (p < 0.01) in HRQoL compared with symptomatic and asymptomatic patients. Significant decrements (p < 0.01) were observed for disability, general health, energy and symptoms for patients who progressed to symptomatic disease from an asymptomatic status. Individuals who had decreasing CD4+ counts also had significant declines (p < 0.001) in disability, general health, social functioning, pain and symptoms. The AIDS-HAQ is an instrument that can be used when comparing group differences and within group changes in observational databases, naturalistic studies and clinical trials. PMID:9330550

    Aim This study examined the impact of taking or not taking antiretroviral (ARV) medications on stigma, as reported by people living with HIV infection in five African countries. Design A two group (taking or not taking ARVs) by three (time) repeated measures analysis of variance examined change in reported stigma in a cohort sample of 1,454 persons living with HIV infection in Lesotho, Malawi, South Africa, Swaziland, and Tanzania. Participants self-reported taking ARV medications and completed a standardized stigma scale validated in the African context. Data were collected at three points in time, from January 2006 to March 2007. Participants taking ARV medications self-reported a mean CD4 count of 273 and those not taking ARV self-reported a mean CD4 count of 418. Results Both groups reported significant decreases in total HIV stigma over time; however, people taking ARVs reported significantly higher stigma at Time 3 compared to those not taking ARVs. Discussion This study documents that this sample of 1,454 HIV infected persons in five countries in Africa reported significantly less HIV stigma over time. In addition, those participants taking ARV medications experienced significantly higher HIV stigma over time compared to those not taking ARVs. This finding contradicts some authors’ opinions that when clients enroll in ARV medication treatment it signifies that they are experiencing less stigma. This work provides caution to health care providers to alert clients new to ARV treatment that they may experience more stigma from their families and communities when they learn they are taking ARV medications.

    The significance of elevated plasma levels of bacterial lipopolysaccharide (LPS) in persons with chronic HIV infection remains undefined. We measured LPS levels by use of limulus lysate assay, and DNA sequences encoding bacterial ribosomal 16S RNA (16S rDNA) were assessed by quantitative polymerase chain reactions in plasma samples obtained from 242 donors. Plasma levels of 16S rDNA were significantly higher in human immunodeficiency virus (HIV)–infected subjects than in uninfected subjects, and they correlated with LPS levels. Higher levels of 16S rDNA were associated with higher levels of T cell activation and with lower levels of CD4 T cell restoration during antiretroviral therapy. Antiretroviral therapy reduces but does not fully normalize plasma levels of bacterial 16S rDNA, an index of microbial translocation from the gastrointestinal tract. High levels of 16S rDNA during therapy are strongly associated with reduced increases in the CD4+ T lymphocyte count, irrespective of plasma HIV RNA levels. These findings are consistent with the importance of microbial translocation in immunodeficiency and T cell homeostasis in chronic HIV infection. PMID:19265479

    The Centers for Disease Control and Prevention (CDC) recommends annual HIV screening for persons at high risk for HIV infection. We assessed the testing history and factors associated with recent testing (tested in the last 12 months) among persons at high risk for HIV infection. We analyzed 2006-2010 National Survey of Family Growth data and classified respondents aged 15-44 who reported a sexual or drug-use risk behavior in the past year as 'high-risk'. Logistic regression models estimated prevalence ratios assessing the association between demographic and health-related factors and having been recently tested for HIV compared with never been tested. Among high-risk men, 29.3% had recently tested for HIV, 30.7% tested more than 12 months ago, and 40.0% had never been tested. Among high-risk women, 38.0% had recently tested, 36.9% tested more than 12 months ago, and 26.1% had never been tested. Compared with men who were aged 15-19, white, heterosexual, and had not recently visited a doctor, men who were aged 40-44, black/African American, homosexual/gay or bisexual, and had visited a doctor in the past year were more likely to have recently tested. Compared with women who were white, had not recently visited a doctor, and had never been pregnant, women more likely to have recently tested were black/African American, had visited a doctor in the past year, and had been pregnant. Approximately two-thirds of high-risk men and women had not been recently tested for HIV. CDC recommendations for annual screening are not being implemented for the majority of persons at risk.

    Background With increased life expectancy for HIV-infected persons, there is concern regarding comorbid depression because of its common occurrence and association with behaviors that may facilitate HIV transmission. Our objectives were to estimate the prevalence of current depression among HIV-infected persons receiving care and assess the burden of major depression, relative to that in the general population. Methods and Findings We used data from the Medical Monitoring Project (MMP) and the Behavioral Risk Factors Surveillance System (BRFSS). The eight-item Patient Health Questionnaire was used to identify depression. To assess the burden of major depression among HIV-infected persons receiving care, we compared the prevalence of current major depression between the MMP and BRFSS populations using stratified analyses that simultaneously controlled for gender and, in turn, each of the potentially confounding demographic factors of age, race/ethnicity, education, and income. Each unadjusted comparison was summarized as a prevalence ratio (PR), and each of the adjusted comparisons was summarized as a standardized prevalence ratio (SPR). Among HIV-infected persons receiving care, the prevalence of a current episode of major depression and other depression, respectively, was 12.4% (95% CI: 11.2, 13.7) and 13.2% (95% CI: 12.0%, 14.4%). Overall, the PR comparing the prevalence of current major depression between HIV-infected persons receiving care and the general population was 3.1. When controlling for gender and each of the factors age, race/ethnicity, and education, the SPR (3.3, 3.0, and 2.9, respectively) was similar to the PR. However, when controlling for gender and annual household income, the SPR decreased to 1.5. Conclusions Depression remains a common comorbidity among HIV-infected persons. The overall excess burden among HIV-infected persons receiving care is about three-times that among the general population and is associated with differences in annual

    Hepatitis E virus (HEV) is a single-stranded RNA virus that can cause hepatitis in an epidemic fashion. HEV usually causes asymptomatic or limited acute infections in immunocompetent individuals, whereas in immunosuppressed individuals such as transplant recipients, HEV can cause chronic infections. The risks and outcomes of HEV co-infection in patients infected with human immunodeficiency virus (HIV) are poorly characterized. We used a third generation immunoassay to measure serum IgG antibodies specific for HEV in 204 HIV-infected individuals from Argentina and a control group of 433 HIV-negative individuals. We found 15 of 204 (7.3%, 95%CI 3.74-10.96%) individuals in the HIV-positive group to have positive HEV IgG levels suggestive of previous infection, compared to 19 of 433 (4.4%, 95% CI 2.5-6.3%) individuals in the HIV-negative control group (p = 0.12). Among HIV-positive individuals, those with HEV seropositivity had lower CD4 counts compared to those that were HEV seronegative (average CD4 count of 234 vs 422 mm3, p = 0.01), indicating that patients with lower CD4 counts were more likely to be HEV IgG positive. Moreover, HEV seropositivity in patients with CD4 counts <200 mm3 was 16%, compared to 4.5% in those with CD4 counts >200 mm3 (p = 0.012). We found a positive PCR result for HEV in one individual. Our study found that increased seroprevalence of HEV IgG correlated with lower CD4 counts in HIV-infected patients in Argentina. PMID:27467394

    HIV infection can cause direct and indirect damage to the brain and is consistently associated with neurocognitive disorders, including impairments in decision-making capacities. The tendency to devalue rewards that are delayed (temporal discounting) is relevant to a range of health risk behaviors. Making choices about delayed rewards engages the executive control network of the brain, which has been found to be affected by HIV. In this case-control study of 18 HIV-positive and 17 HIV-negative adults, we examined the effects of HIV on brain activation during a temporal discounting task. Functional MRI (fMRI) data were collected while participants made choices between smaller, sooner rewards and larger, delayed rewards. Choices were individualized based on participants' unique discount functions, so each participant experienced hard (similarly valued), easy (disparately valued), and control choices. fMRI data were analyzed using a mixed-effects model to identify group-related differences associated with choice difficulty. While there was no difference between groups in behavioral performance, the HIV-positive group demonstrated significantly larger increases in activation within left parietal regions and bilateral prefrontal regions during easy trials and within the right prefrontal cortex and anterior cingulate during hard trials. Increasing activation within the prefrontal regions was associated with lower nadir CD4 cell count and risk-taking propensity. These results support the hypothesis that HIV infection can alter brain functioning in regions that support decision making, providing further evidence for HIV-associated compensatory activation within fronto-parietal cortices. A history of immunosuppression may contribute to these brain changes. Hum Brain Mapp 37:2455-2467, 2016. © 2016 Wiley Periodicals, Inc. PMID:27004729

    Human papillomavirus (HPV) is a common sexually transmitted virus and an important etiologic factor in head and neck cancers. HIV-infected individuals are at increased risk of developing oropharyngeal cancers (OPC) compared with the general population. HPV-positive OPC are also increasingly a significant cause of morbidity and mortality for HIV-infected individuals in the era of effective combination antiretroviral therapy. The epidemiology and natural history of oral HPV infection have not been well established, but it appears that oral HPV infection is less common than anal infection, and more common among HIV-infected persons than the general population. Prevention of OPC is therefore increasingly important in HIV-infected individuals. Although not demonstrated in randomized controlled trials, HPV vaccination may prevent oral HPV infection as well. The focus of organized HPV cancer prevention programs should include prophylactic HPV vaccination to reduce the burden of high-risk HPV and low-risk HPV types who have not yet been exposed.

When prescribing immunizations and specific chemoprophylaxis, the stage of immunodeficiency as well as drug interactions with antiretrovirals and medicaments against opportunistic infections have to be taken into account. Live vaccines may be contraindicated. Immunocompromised HIV-infected travellers have a higher risk for serious courses of diseases by enteropathogens. Therefore a good information about food hygiene is important and a prescription of an antibiotic to take in case of severe diarrhea may be indicated. A new antiretroviral combination therapy should not be started immediately before travelling to the tropics. The possibility to continue an established HIV treatment during travel has to be evaluated cautiously. With good pre-travel advice the risk of severe health problems is low for most HIV-infected travellers. PMID:11441700

    Background Optimal antiretroviral therapy (ART) effectiveness depends upon medication adherence, which is a complex behavior with many contributing factors including neurocognitive function. Pharmacy refill records offer a promising and practical tool to assess adherence. Methods A substudy of the CHARTER (CNS HIV Anti-Retroviral Therapy Effects Research) study was conducted at the Johns Hopkins University (JHU) and the University of Washington (UW). Pharmacy refill records were the primary method to measure ART adherence, indexed to a “sentinel” drug with the highest central nervous system penetration effectiveness score. Standardized neuromedical, neuropsychological, psychiatric and substance use assessments were performed at enrollment and at 6 months. Regression models were used to determine factors associated with adherence and the relationships between adherence and change in plasma and cerebrospinal fluid HIV RNA concentrations between visits. Results Among 80 (33 JHU, 47 UW) participants, the mean adherence score was 86.4% with no difference by site. In the final multivariable model, better neurocognitive function was associated with better adherence, especially among participants who were at JHU, male, and HIV-infected for a longer time-period. Worse performance on working memory tests was associated with worse adherence. Better adherence predicted greater decreases in cerebrospinal fluid HIV RNA between visits. Conclusion Poorer global neurocognitive functioning and deficits in working memory were associated with lower adherence defined by a pharmacy refill record measure, suggesting that assessments of cognitive function, and working memory in particular, may identify patients at risk for poor ART adherence who would benefit from adherence support.

    2012-01-01

    Background Most clinical guidelines recommend that AIDS-free, HIV-infected persons with CD4 cell counts below 0.350 × 109 cells/L initiate combined antiretroviral therapy (cART), but the optimal CD4 cell count at which cART should be initiated remains a matter of debate. Objective To identify the optimal CD4 cell count at which cART should be initiated. Design Prospective observational data from the HIV-CAUSAL Collaboration and dynamic marginal structural models were used to compare cART initiation strategies for CD4 thresholds between 0.200 and 0.500 × 109 cells/L. Setting HIV clinics in Europe and the Veterans Health Administration system in the United States. Patients 20 971 HIV-infected, therapy-naive persons with baseline CD4 cell counts at or above 0.500 × 109 cells/L and no previous AIDS-defining illnesses, of whom 8392 had a CD4 cell count that decreased into the range of 0.200 to 0.499 × 109 cells/L and were included in the analysis. Measurements Hazard ratios and survival proportions for all-cause mortality and a combined end point of AIDS-defining illness or death. Results Compared with initiating cART at the CD4 cell count threshold of 0.500 × 109 cells/L, the mortality hazard ratio was 1.01 (95% CI, 0.84 to 1.22) for the 0.350 threshold and 1.20 (CI, 0.97 to 1.48) for the 0.200 threshold. The corresponding hazard ratios were 1.38 (CI, 1.23 to 1.56) and 1.90 (CI, 1.67 to 2.15), respectively, for the combined end point of AIDS-defining illness or death. Limitations CD4 cell count at cART initiation was not randomized. Residual confounding may exist. Conclusion Initiation of cART at a threshold CD4 count of 0.500 × 109 cells/L increases AIDS-free survival. However, mortality did not vary substantially with the use of CD4 thresholds between 0.300 and 0.500 ×109 cells/L. Primary Funding Source National Institutes of Health. PMID:21502648

    The presence of platelet- and neutrophil-bound immunoglobulin (PBIg and NBIg) in thrombocytopenic or neutropenic HIV-infected individuals has led to the concept that in HIV infection thrombocytopenia and neutropenia are mediated by autoimmunity. However, PBIg and NBIg were also demonstrated in non-cytopenic HIV-infected individuals. We determined the prevalence of autoantibodies against neutrophils and platelets by immunofluorescence in randomly chosen persons in different stages of asymptomatic and symptomatic HIV infection. Platelet and neutrophil autoantibodies already appeared in the asymptomatic stage and their prevalence further increased in the symptomatic stages. No correlation was found between the presence of either platelet or neutrophil antibodies and the occurrence of circulating immune complexes in the blood or the serum immunoglobulin level. There was no significant difference in neutrophil counts in HIV-infected persons with or without neutrophil autoantibodies. In addition, no significant difference in neutrophil count was found between HIV-infected and non-HIV-infected persons. HIV-infected individuals with platelet autoantibodies tended to have a lower platelet count than HIV-infected individuals without these antibodies. However, the platelet count in HIV-infected individuals without platelet antibodies was significantly lower than in the non-HIV infected persons. Thus, autoantibodies against platelets and neutrophils occur early in HIV infection and their prevalence is correlated with disease progression. Their presence is associated with cytopenia only in a limited number of persons. Non-immune mechanisms also mediate thrombocytopenia in HIV infection. PMID:1974174

    Continuous HIV treatment is necessary to ensure successful combined antiretroviral therapy (cART). The aim of this study was to evaluate the incidence of patient-initiated non-structured treatment interruptions in HIV-infected persons who inject drugs and who received a multidisciplinary comprehensive program, including medical HIV care, drug-dependence treatment and psychosocial support, at a drug outpatient addiction center. Non-structured treatment interruptions were defined as ≥30 consecutive days off cART without medical indication. During a median follow-up of 53.8 months, 37/132 (28 %) patients experienced the first non-structured treatment interruptions. The cumulative probability of cART interruption at 5 years was 31.2 % (95 % CI 22.4-40.0). Current drug use injection ≥1/day (HR 14.77; 95 % CI 5.90-36.96) and cART naive patients (HR 0.35, 95 % CI 0.14-0.93) were predictive factors for non-structured treatment interruptions. HIV care provided at a drug addiction center is a useful strategy to sustain continuous cART, however, drug abstinence is essential for the long-term maintenance of cART. PMID:26427376

    HIV primary infection occurs at mucosa tissues, suggesting an intricate interplay between microbiome and HIV infection. Recent advanced technologies of high-throughput sequencing and bioinformatics allow researchers to explore nonculturable microbes including bacteria, virus and fungi and their association with diseases. HIV/SIV infection is associated with microbiome shifts and immune activation that may affect the outcome of disease progression. Similarly, altered microbiome and inflammation are associated with increased risks of HIV acquisition, suggesting the role of microbiome in HIV transmission. In this review, we will focus on microbiome in HIV infection at various mucosal compartments. Understanding the relationship between microbiome and HIV may offer insights into development of better strategies for HIV prevention and treatment. PMID:25439273

    The HITECH Act signed into law in 2009 requires hospitals to provide patients with electronic access to their health information through an electronic personal health record (ePHR) in order to receive Medicare/Medicaid incentive payments. Little is known about who uses these systems or the impact these systems will have on patient outcomes in HIV care. The health care empowerment model provides rationale for the hypothesis that knowledge from an electronic personal health record can lead to greater patient empowerment resulting in improved outcomes. The objective was to determine the patient characteristics and patient activation, empowerment, satisfaction, knowledge of their CD4, Viral Loads, and antiretroviral medication, and medication adherence outcomes associated with electronic personal health record use in Veterans living with HIV at the San Francisco VA Medical Center. The participants included HIV-Infected Veterans receiving care in a low volume HIV-clinic at the San Francisco VA Medical Center, divided into two groups of users and non-users of electronic personal health records. The research was conducted using in-person surveys either online or on paper and data abstraction from medical records for current anti-retroviral therapy (ART), CD4 count, and plasma HIV-1 viral load. The measures included the Patient Activation Measure, Health Care Empowerment Inventory, ART adherence, provider satisfaction, current CD4 count, current plasma viral load, knowledge of current ART, knowledge of CD4 counts, and knowledge of viral load. In all, 40 participants were recruited. The use of electronic personal health records was associated with significantly higher levels of patient activation and levels of patient satisfaction for getting timely appointments, care, and information. ePHR was also associated with greater proportions of undetectable plasma HIV-1 viral loads, of knowledge of current CD4 count, and of knowledge of current viral load. The two groups differed

Currently, the figures have a tendency to stabilization, but there is an increase in the persantage of HIV-infected persons performing military service under the contract, as well as the actualization sexual way of infection. The insufficient effectiveness of the barrier screening during the laboratory examination of recruits may contribute the increase in the incidence of HIV infection. Have been reviewed the questions medical-diagnostic and medical-psychological support of HIV-infected soldiers. Been analyzed the social consequences of delays in seeking medical help of patients in this group, the opportunities and challenges of their dispensary observation. It was noted that early detection of HIV infection and proper medical and psychological support in the dynamics of pathological process helps to reduce the number of new cases and improve their outcomes and to reduce the period of efficiency recovery of military personnel.

    Collaborative studies to determine the consequences of pregnancy in HIV infected women have been begun in the last 2 years. Both HIV and HIV antibodies pass through the placenta, and 30-50% of infants born to HIV infected mothers are infected in utero. In developed countries it is feasible to screen pregnant women in high risk groups for HIV positivity. In developing countries, where heterosexual transmission is the main route of infection, there are no high risk groups, and it is not feasible to screen all pregnant women. Some data have shown that HIV infection in pregnancy is associated with intrauterine growth retardation, low birth weight, and high infant mortality. There is no evidence that cesarean section reduces infection in neonates, and it should not be performed on HIV infected women. By 1987 almost 1.5% of AIDS cases in the US were in vertically infected infants. In Africa also the main factor in HIV in infancy is vertical transmission. AIDS in infancy follows 1 of 2 distinct patterns: failure to thrive and death from Pneumocystis carinii pneumonia within the 1st year or else apparent health during infancy but death from opportunistic infections by age 3. HIV infection in childhood is uncommon and can usually be traced to blood transfusions or unsterilized needles used for vaccinations. Neurological symptoms often develop early in children. Breast feeding probably does not infect any infants who have not already been infected in utero, and in developing counties breast feeding is still the best assurance of total nutrition. Pooled, unpasteurized milk banks, on the other hand, represent an unnecessary danger, and milk donors should be screened. Since there is no evidence that routine immunization accelerates the course of HIV infection, and since mass screening is not feasible in developing countries, the World Health Organization recommends that routine immunizations be continued. Since the best protection from in utero HIV infection is the use of

    Killing of CD4 lymphocytes and systemic immune suppression are the hallmarks of HIV infection. These milestones are produced by different mechanisms that draw a complex picture of AIDS immunopathogenesis. The role of the GALT system as a preferential target for HIV, chronic activation of the immune system and viral escape mechanisms are recent challenges that have changed our current view on the mechanisms leading to immune destruction and development of AIDS. In this article, the mechanisms of immune suppression, the evolution of immune response throughout the infection and the mechanisms of viral escape are analysed. PMID:21388715

    Pneumocystosis is an opportunistic disease caused by invasion of unicellular fungus Pneumocystic jirovecii which is responsible for febrile pneumonia among patients with cellular immunodeficiency especially those HIV infected. Despite the decreasing of its incidence due to the introduction of antiretroviral therapy, as well as anti-Pneumocystis prophylaxis among these patients, Pneumocystis pneumonia remains the first AIDS-defining event and a leading cause of mortality among HIV-infected patients. The usual radiological presentation is that of diffuse interstitial pneumonia. The diagnosis is confirmed by the detection of trophozoides and/or cysts P. jirovecii in bronchoalveolar lavage (BAL) samples using several staining techniques. The use of polymerase chain reaction in the BAL samples in conjunction with standard immunofluorescent or colorimetric tests have allowed for more has allowed for more rapid and accurate diagnosis. The standard regimen of treatment is the association of trimethoprim-sulfamethoxazole which has been utilized as an effective treatment with a favourable recovery. Early HIV diagnosis and antiretroviral therapy should reduce the incidence of this dreaded disease. PMID:27349824

    The incidence of lymphoma in patients with HIV infection greatly exceeds that of the general population. The increased risk for lymphoma appears related to multiple factors, including the transforming properties of the retrovirus itself, the immunosuppression and cytokine dysregulation that results from the disease, and, most importantly, opportunistic infections with other lymphotrophic herpes viruses such as Epstein–Barr virus and human herpesvirus 8. Histologically lymphomas fall into three groups: (1) those also occurring in immunocompetent patients; (2) those occurring more specifically in HIV‐positive patients; and (3) those also occurring in patients with other forms of immunosuppression. Aggressive lymphomas account for the vast majority cases. They frequently present with advanced stage, bulky disease with high tumour burden and, typically, involve extranodal sites. Clinical outcome appears to be worse than in similar aggressive lymphomas in the general population. However, following the introduction of highly active antiretroviral therapy, the risk for developing lymphoma in the context of HIV infection has decreased and the clinical outcome has improved.

The highest levels of primary morbidity are registered in persons aged 20-39 years. The established epidemiological parallels between HIV infection and parenteral hepatitis require the development of the unified strategy of the prophylaxis of these diseases on the federal and regional levels.

    Microbial translocation from the gut is associated with immune dysfunction, persistent inflammation, and likely plays a role in the pathogenesis of neurocognitive dysfunction during HIV infection. (1→3)-β-D-Glucan (BDG) is a component of most fungal cell walls and might be a useful indicator of gut mucosal barrier impairment. The objective of this study was to evaluate whether higher blood BDG levels correlate with impaired neurocognitive functioning in a cohort of HIV-infected adults with suppressed levels of HIV RNA in blood plasma. In this cross-sectional cohort study, we measured levels of BDG in blood plasma and cerebrospinal fluid (CSF) supernatant samples in a cohort of adults with acute/early HIV infection, who initiated antiretroviral therapy (ART) during the earliest phase of infection and achieved suppressed levels of HIV RNA in blood plasma (<50 copies/mL) thereafter. We compared BDG with established biomarkers of microbial translocation, immune activation, and cognitive dysfunction (evaluated by global deficit score). We found that higher blood BDG levels were significantly related to higher global deficit scores, reflecting worse neurocognitive performance (Spearman r = 0.47; P = 0.042) among HIV-infected adults with suppressed viral loads who initiated ART early in infection. Two CSF samples presented elevated BDG levels. Interestingly, these 2 samples originated from the 2 subjects with the highest global deficit scores of the cohort. BDG may be a promising independent biomarker associated with neurocognitive functioning in virologically suppressed HIV-infected individuals. PMID:26986173

    Interstitial nephritis is a common cause of renal dysfunction. It is primarily caused by drugs, infections, or autoimmune disorders. Patients with human immunodeficiency virus (HIV) infection can develop interstitial nephritis, although it typically occurs because of the aforementioned etiologies and not as a direct consequence of HIV infection. Interstitial lesions may occur in patients with HIV-associated nephropathy (HIVAN). However, interstitial nephritis without the glomerular injuries characteristic of HIVAN, and without the risk factors described earlier, is very rare.

    Migrants represent around one third of patients newly diagnosed with HIV in Spain and they constitute a population with higher vulnerability to its negative consequences due to the socio-cultural, economical, working, administrative and legal contexts. Migrants are diagnosed later, which worsens their individual prognosis and facilitates the maintenance of the HIV epidemic. In spite of the different barriers they experience to access healthcare in general, and HIV-related services in particular, access to antiretroviral treatment has been similar to that of the autochthonous population. However, benefits of treatment have been not, with women in general and men from Sub-Saharan Africa exhibiting the worse response to treatment. We need to proactively promote earlier diagnosis of HIV infection, the adoption of preventive measures to avoid new infections, and to deliver accessible, adapted and high-quality health-care.

    Purpose Noninfectious comorbidities such as cardiovascular diseases have become increasingly prevalent and occur earlier in life in persons with HIV infection. Despite the emerging body of literature linking environmental exposures to chronic disease outcomes in the general population, the impacts of environmental exposures have received little attention in HIV-infected population. The aim of this study is to investigate whether individuals living with HIV have elevated prevalence of heavy metals compared to non-HIV infected individuals in United States. Methods We used the National Health and Nutrition Examination Survey (NHANES) 2003-2010 to compare exposures to heavy metals including cadmium, lead, and total mercury in HIV infected and non-HIV infected subjects. Results In this cross-sectional study, we found that HIV-infected individuals had higher concentrations of all heavy metals than the non-HIV infected group. In a multivariate linear regression model, HIV status was significantly associated with increased blood cadmium (p=0.03) after adjusting for age, sex, race, education, poverty income ratio, and smoking. However, HIV status was not statistically associated with lead or mercury levels after adjusting for the same covariates. Conclusions Our findings suggest that HIV-infected patients might be significantly more exposed to cadmium compared to non-HIV infected individuals which could contribute to higher prevalence of chronic diseases among HIV-infected subjects. Further research is warranted to identify sources of exposure and to understand more about specific health outcomes. PMID:24023932

    Background Following HIV-1 acquisition, many individuals develop an acute retroviral syndrome and a majority seek care. Available antibody testing cannot detect an acute HIV infection, but repeat testing after 2–4 weeks may detect seroconversion. We assessed the effect of appointment reminders on attendance for repeat HIV testing. Methods We enrolled, in a randomized controlled trial, 18–29 year old patients evaluated for acute HIV infection at five sites in Coastal Kenya (ClinicalTrials.gov NCT01876199). Participants were allocated 1:1 to either standard appointment (a dated appointment card) or enhanced appointment (a dated appointment card plus SMS and phone call reminders, or in-person reminders for participants without a phone). The primary outcome was visit attendance, i.e., the proportion of participants attending the repeat test visit. Factors associated with attendance were examined by bivariable and multivariable logistic regression. Principal Findings Between April and July 2013, 410 participants were randomized. Attendance was 41% (85/207) for the standard group and 59% (117/199) for the enhanced group, for a relative risk of 1.4 [95% Confidence Interval, CI, 1.2–1.7].Higher attendance was independently associated with older age, study site, and report of transactional sex in past month. Lower attendance was associated with reporting multiple partners in the past two months. Conclusions Appointment reminders through SMS, phone calls and in-person reminders increased the uptake of repeat HIV test by forty percent. This low-cost intervention could facilitate detection of acute HIV infections and uptake of recommended repeat testing. Trial Registration Clinicaltrials.gov NCT01876199 PMID:27077745

HIV infection for those in treatment has become a complex chronic disease in which end-organ injury and resulting morbidity, functional decline, and mortality do not have a single etiology but reflect cumulative loss of organ system reserve from multiple interacting sources leading to functional decline, organ system failure, and death. Emerging guidelines and recommendations suggest a need for increased awareness and treatment of the multifaceted needs of the aging HIV-infected patient. PMID:27109276

    Summary Most infants born to human immunodeficiency virus (HIV)-infected women escape HIV infection. Infants evade infection despite an immature immune system and, in the case of breastfeeding, prolonged repetitive, exposure. If infants become infected, the course of their infection and response to treatment differs dramatically depending upon the timing (in utero, intrapartum, or during breastfeeding) and potentially the route of their infection. Perinatally acquired HIV infection occurs during a critical window of immune development. HIV’s perturbation of this dynamic process may account for the striking age-dependent differences in HIV disease progression. HIV infection also profoundly disrupts the maternal immune system upon which infants rely for protection and immune instruction. Therefore, it is not surprising that infants who escape HIV infection still suffer adverse effects. In this review, we highlight the unique aspects of pediatric HIV transmission and pathogenesis with a focus on mechanisms by which HIV infection during immune ontogeny may allow discovery of key elements for protection and control from HIV.

    Therapeutic goals for HIV-infected patients receiving antiretroviral therapy include minimizing risk of future physical disability. Presarcopenia and sarcopenia precede age-associated physical disability. We investigated their prevalence and the predictive value of patient mid-upper arm circumference (MUAC) for them. Eighty community-dwelling patients ≥45 years old demonstrating durable viral suppression were evaluated. Sarcopenia was defined as low skeletal muscle index (SMI, skeletal muscle kg/height m(2)) and either low strength or poor performance by handgrip dynamometry and gait speed, respectively. Presarcopenia was defined as low SMI only. MUAC was interpreted according to National Health Statistics percentile. Prevalence of sarcopenia and presarcopenia was 5.0% and 20.0%, respectively. Male gender (odds ratio [OR] 10.72; P < .026), recreational psychoactive substance use (OR 5.13; P < .037), and intravenous drug use transmission category (OR 6.94; P <.0327) were associated with presarcopenia. Higher body mass index (OR 0.80; P < .0007), MUAC (OR 0.83; P < .024), and large skeletal frame (OR 0.09; P < .003) were negatively associated with presarcopenia. Finding that a participant did not have a MUAC <25th percentile on physical examination had a 90.4% negative predictive value for presarcopenia. Although sarcopenia was uncommon, presarcopenia was highly prevalent in midlife and older HIV-infected males. Determination of MUAC percentile may identify those least likely to demonstrate skeletal muscle deficit and improve patient selection for mass and function testing. PMID:24067494

  6. Acute HIV infection - New York City, 2008.

    PubMed

    2009-11-27

    Acute human immunodeficiency virus (HIV) infection (AHI) is a highly infectious phase of disease that lasts approximately 2 months and is characterized by nonspecific clinical symptoms. AHI contributes disproportionately to HIV transmission because it is associated with a high level of viremia, despite negative or indeterminate antibody (Ab) tests. Diagnosis of AHI with individual or pooled nucleic acid amplification tests (p-NAAT) can enable infected persons to adopt behaviors that reduce HIV transmission, facilitate partner referral for counseling and testing, and identify social networks of persons with elevated rates of HIV transmission. The national HIV surveillance case definition does not distinguish AHI from other stages of HIV infection, and the frequency of AHI among reported HIV cases is unknown. In 2008, to increase detection of AHI and demonstrate the feasibility of AHI surveillance, the New York City Department of Health and Mental Hygiene (NYC DOHMH) initiated p-NAAT screening at four sexually transmitted disease (STD) clinics and enhanced citywide HIV surveillance (using a standard case definition) to differentiate AHI among newly reported cases. Seventy cases of AHI (representing 1.9% of all 3,635 HIV diagnoses reported in New York City) were identified: 53 cases from enhanced surveillance and 17 cases from p-NAAT screening (representing 9% of 198 HIV diagnoses at the four clinics). Men who have sex with men (MSM) constituted 81% of AHI cases. Screening STD clinic patients, especially MSM, with p-NAAT can identify additional cases of HIV infection. Surveillance for AHI is feasible and can identify circumstances in which HIV prevention efforts should be intensified. PMID:19940835

    Although the number of new infections has declined recently, women still constitute almost half of the world's 34 million people with HIV infection, and HIV remains the leading cause of death among women of reproductive age. Prevention research has made considerable progress during the past few years in addressing the biological, behavioral and social factors that influence women's vulnerability to HIV infection. Nevertheless, substantial work still must be done in order to implement scientific advancements and to resolve the many questions that remain. This article highlights some of the recent advances and persistent gaps in HIV prevention research for women and outlines key research and policy priorities. PMID:23764631

    Summary Recent advances in the immunology, pathogenesis, and prevention of human immunodeficiency virus (HIV) infection continue to reveal clues to the mechanisms involved in the progressive immunodeficiency attributed to infection but more importantly have shed light on the correlates of immunity to infection and disease progression. HIV selectively infects, eliminates, and/or dysregulates several key cells of the human immune system, thwarting multiple arms of the host immune response, and inflicting severe damage to mucosal barriers, resulting in tissue infiltration of ‘symbiotic’ intestinal bacteria and viruses that essentially become opportunistic infections promoting systemic immune activation. This leads to activation and recruitment or more target cells for perpetuating HIV infection, resulting in persistent, high level viral replication in lymphoid tissues, rapid evolution of resistant strains, and continued evasion of immune responses. However, vaccine studies and studies of spontaneous controllers are finally providing correlates of immunity from protection and disease progression, including virus-specific CD4+ T-cell responses, binding antibodies, innate immune responses, and generation of antibodies with potent antibody-dependent cell-mediated cytotoxicity activity. Emerging correlates of immunity indicate that prevention of HIV infection may be possible through effective vaccine strategies that protect and stimulate key regulatory cells and immune responses in susceptible hosts. Further, immune therapies specifically directed towards boosting specific aspects of the immune system may eventually lead to a cure for HIV-infected patients. PMID:23772612

  11. Spatiotemporal dynamics of HIV infection

    NASA Astrophysics Data System (ADS)

    Strain, Matthew Carl

    Mathematical models of the dynamics of infection with the human immunodeficiency virus (HIV) have contributed to tremendous advances over the past 20 years. This thesis extends this previous work by exploring the importance of spatial heterogeneity in HIV infection both in vitro and in vivo in patients treated with highly-active antiretroviral therapy. Viral infections propagate locally in space, yet HIV infection has been widely regarded as equilibrated over the entire body of an infected patient. This dissertation constructs and explores a cellular automata model of viral spread at the cellular level. Coupling the automata to a blood compartment represented by a differential equation leads to a whole-body model of HIV infection that explicitly includes spatial effects at both the cellular and tissue levels. These models are tested by comparison with experimental data. A central prediction of the spatial model is that, due to competition between Brownian motion and viral lability, HIV infectivity increases with target cell density. This production is verified in a series of in vitro experiments in cell culture. The predicted independence of inhibitory concentrations of antiretoviral agents is verified for nevirapine, but azidothymidine inhibits HIV replication less efficiently in more dense cultures. These in vitro results suggest that systems allowing cell concentrations closer to tissue densities would better reflect virus replication kinetics, although standard measures of relative drug susceptibility may accurately reflect in vivo conditions. The coupled spatial model of in vivo dynamics is compared with novel mathematical analysis of experiments in HIV-infected patients. These analyses indicate that HIV DNA provides a useful marker of the size of long-lived cellular reservoirs of HIV. Levels of HIV DNA in peripheral blood are predictive of the average rate of residual virus production after years of treatment, regardless of whether patients initiate therapy

    HIV-infected women carry a significant burden on HPV infection and associated diseases. As HIV-infected individuals are living longer, the prevalence of HPV infection is rising and HPV-associated cytologic abnormalities remain high despite successful treatments of HIV infection. Several HPV vaccines are currently available and recommended for adolescents and adults up to age 26. The vaccine is safe, immunogenic and effective in preventing diseases due to HPV types included in the vaccines, particularly among persons without prior HPV exposure. This review summarizes available data on the use of the HPV vaccines among HIV infected women. The immunogenicity and safety of the vaccine is highlighted and in particular, barriers to vaccination among HIV infected women are discussed. PMID:26599305

    Abstract The data, concerning clinic--epidemiologic and clinic--nosological characteristic of a HIV-infected injured persons in polytrauma were adduced. There was established, that polysystemic injuries (PSI) in a HIV-infected persons occur in a younger injured patients, a trauma environment is quite a speciphic one (criminal trauma prevails), as well as mechanism of the injury occurrence (falling down is much more freqent), and the risk of a lethal outcome is determined by predominantly cranial, thoracic and abdominal components of injury. A lethal outcome occurrence risk in HIV-infected injured persons in PSI in accordance to the age signs and traumagenesis is lesser, than in a control body. It is necessary to prolong the investigations, concerning studying this phenomenon and other peculiarities of a traumatic disease in HIV-infected injured persons in polytrauma. PMID:27244924

    The review summarizes data of recent studies on the impact of human gene polymorphisms on the possibility of HIV infection, as well as the specific features of its pathogenesis, the efficiency of HIV infection treatment and the likelihood of its complication. Main information on the mechanisms responsible for viral penetration into the sensitive cells, for immune response development and involvement of HLA and KIR molecules in this process are briefly outlined. Idea on major cell proteins affecting drug metabolism and excretion and encoding for their genes are generalized. There are many examples that show how different human gene alleles and their combinations affect the nature of the pathogenetic process and the occurrence and degree of adverse reactions. The first example of successfully using the prognostic genetic analysis (HLA-B*5701) registered in 2008 to upgrade the quality of HIV infection treatment is described in detail. Basic requirements for further genetic tests to use the optimal antiretroviral therapy schemes and to reduce its hazardous effects are formulated. PMID:20481056

    The prevalence of HIV (human immunodeficiency virus) associated neurocognitive disorders (HAND) will undoubtedly increase with the improved longevity of HIV-infected persons. HIV infection, itself, as well as multiple physiologic and psychosocial factors can contribute to cognitive impairment and neurologic complications. These comorbidities confound the diagnosis, assessment, and interventions for neurocognitive disorders. In this review, we discuss the role of several key comorbid factors that may contribute significantly to the development and progression of HIV-related neurocognitive impairment, as well as the current status of diagnostic strategies aimed at identifying HIV-infected individuals with impaired cognition and future research priorities and challenges.

    The Veterans Aging Cohort Study (VACS) Index was developed as a risk index for health outcomes in HIV, and it has been consistently associated with mortality. It shows a significant, yet relatively weak, association with neurocognitive impairment, and little is known about its utility among ethnic/racial minority groups. We examined whether the association between the VACS Index and neurocognition differed by ethnic/racial group. Participants included 674 HIV-infected individuals (369 non-Hispanic whites, 111 non-Hispanic blacks, and 194 Hispanics). Neurocognitive function was assessed via a comprehensive battery. Scaled scores for each neurocognitive test were averaged to calculate domain and global neurocognitive scores. Models adjusting for demographics and HIV disease characteristics not included in the VACS Index showed that higher VACS Index scores (indicating poorer health) were significantly associated with worse global neurocognition among non-Hispanic whites. This association was comparable in non-Hispanic blacks, but nonsignificant among Hispanics (with similar results for English and Spanish speaking). We obtained comparable findings in analyses adjusting for other covariates (psychiatric and medical comorbidities and lifestyle factors). Analyses of individual neurocognitive domains showed similar results in learning and delayed recall. For other domains, there was an effect of the VACS Index and no significant interactions with race/ethnicity. Different components of the VACS Index were associated with global neurocognition by race/ethnicity. In conclusion, the association between the VACS Index and neurocognitive function differs by ethnic/racial group. Identifying key indicators of HIV-associated neurocognitive impairment by ethnic/racial group might play an important role in furthering our understanding of the biomarkers of neuroAIDS.

    High prevalence of tobacco use and low success in quitting remain significant problems for reducing disease burden among HIV-infected persons. This study's purpose was to examine participant responsiveness and tobacco dependence treatment adherence and their influences on tobacco abstinence among HIV-infected patients. This non-randomized study included HIV-infected smokers 18 years of age or older, who smoked at least 5 cigarettes per day, and had an interest in quitting smoking in the next 30 days. HIV-infected smokers (n = 247) received a 12-week tobacco dependence treatment intervention that included pharmacotherapy and telephone counseling. Younger age and non-White race were associated with lower adherence to pharmacotherapy. Younger age, non-White race, and increased monthly binge drinking were associated with lower adherence to telephone counseling. High participant responsiveness was associated with adherence to pharmacotherapy, counseling, and abstinence. Development and testing of interventions to improve adherence to evidence-based tobacco dependence treatment is warranted. PMID:25855045

    Insulin resistance is an important and under recognized consequence of HIV treatment. Different studies have yielded widely varying estimates of the prevalence of impaired glucose metabolism in people on highly active antiretroviral therapy (HAART). The risk increases further with hepatitis C co infection. Although Protease inhibitors (PIs) are the main drug class implicated in insulin resistance, some studies have shown an association of increased risk of diabetes with cumulative exposure of nucleoside reverse transcriptase inhibitors (NRTIs). The effect of switching to other antiretrovirals has not been fully determined and the long-term consequences of insulin resistance in this population are not known. Treatment of established diabetes mellitus should generally follow existing guidelines. It is therefore reasonable to recommend general measures to increase insulin sensitivity in all patients infected with HIV, such as regular aerobic exercise and weight reduction for overweight persons. The present review article has the information of some recent patents regarding the insulin resistance in HIV infection. PMID:21824074

    The paper presents a model of CD4 + lymphocyte dynamics in HIV-infected persons. The model incorporates a feedback mechanism regulating the production of T lymphocytes and simulates the dynamics of CD8 + lymphocytes, whose production is assumed to be closely linked to that of CD4 + cells. Because CD4 + lymphocyte counts are a good prognostic indicator of HIV infection, the model was used to simulate such therapeutic interventions as chemotherapy and active and passive immunization. The model also simulated the therapeutic administration of anti-CD8 antibodies; this intervention was assumed to activate T-cell production by activating a feedback mechanism blocked by the high numbers of CD8 + lymphocytes present in HIV-infected persons. The character and implications of the model are discussed in the context of other mathematical models used in HIV infection. PMID:8969246

    HIV infection is associated with chronic immune activation that is superimposed on immunologic senescence in older adults, resulting in the acquisition of age-related diseases at younger ages. The incidence of coronary artery disease is higher among HIV-infected persons than uninfected individuals matched for age and sex. HIV infection and its treatment have been associated with premature bone loss. Lung, hepatic, and anal cancers occur at younger ages in persons with HIV infection. HIV-infected patients are living longer, and proper attention to the management of comorbidities in this population is essential.

    Purpose Examine incidence and factors associated with loss to follow-up (LTFU) in the AIDS Clinical Trials Group (ACTG) Longitudinal Linked Randomized Trials (ALLRT) cohort. Method ALLRT is a prospective cohort of HIV-infected persons randomized to ARV regimens/strategies in ACTG trials and followed long-term after the trial ends. Person-years were calculated from ALLRT entry until LTFU (defined using off-study reasons or ≥3 consecutive missed visits), death/severe debilitation/site closures, or June 2009 (censored). Poisson regression was used to examine LTFU factors separately among participants who were ARV-naïve or ARV-experienced at trial entry. Results Among 4630 participants (22,524 person-years), 1140 were lost to follow-up, 237 died, 29 were severely debilitated, and 443 were at sites that closed. The LTFU incidence was 5.5 and 4.2 per 100 person-years among previously ARV-naïve and ARV-experienced participants, respectively. In both groups, age≤50, site location, being off-ARVs and viral load ≥400 copies/ml were associated with a higher risk of LTFU. Among ARV-naïves, male sex, education<16 years, IV drug use and cigarette smoking were also associated with LTFU. Conclusion Knowledge of differential LTFU can help researchers identify participants at risk of LTFU in longitudinal HIV cohorts and design retention strategies, thereby limiting study bias. The identified factors should be included in inverse probability of weighting models to account for LTFU. PMID:22044855

    Combination antiretroviral therapy can suppress human immunodeficiency virus (HIV) infection but cannot completely eradicate the virus. A major obstacle in the quest for a cure is the difficulty in targeting and measuring latently infected cells. To date, a single person seems to have been cured of HIV. Hematopoietic stem cell transplantation (HSCT) preceded this cancer patient's long-term sustained HIV remission, but researchers have been unable to replicate this cure, and the mechanisms that led to HIV remission remain to be established. In February 2014, the National Institute of Allergy and Infectious Diseases sponsored a workshop that provided a venue for in-depth discussion of whether HSCT could be exploited to cure HIV in cancer patients requiring such procedures. Participants also discussed how HSCT might be applied to a broader community of HIV-infected persons in whom the risks of HSCT currently outweigh the likelihood and benefits of HIV cure.

    Lipoatrophy (LA) is a form of lipodystrophy, characterized by volume depletion caused by fat loss in the limbs, buttocks, and face. Facial volume loss is the most obvious outward sign of LA because it alters the facial contours in the cheeks, temples, and orbits. Lipodystrophy and LA are most commonly seen in patients with HIV on highly active antiretroviral therapy (HAART), which was introduced in the mid-1990s for the management of HIV, and is currently considered the mainstay therapy for HIV-infected patients. However, the etiology of LA is likely multifactorial as underlying patient conditions, including duration and severity of HIV and increasing age, have also been found to contribute to its occurrence. The volume loss of LA can be very dramatic with some patients exhibiting no signs of facial fat. As a result, many HIV-infected patients with associated LA suffer from psychological and lifestyle effects, which can lead to noncompliance with HAART. Thus, increases in facial volume and improvement in morphology is anticipated to reduce anxiety caused by LA in HIV-infected patients, and improve quality of life. This review discusses the benefits and limitations of several treatment options available to correct the volume depletion associated with LA, including antiretroviral switching, permanent surgical implants and injectables, poly-L-lactic acid, collagen, and hyaluronic acid derivatives.

    Comparative analyses of the characteristics of persons living with HIV infection (PLWH) in the United States (US) captured in surveillance and other observational databases are few. To explore potential joint data use to guide HIV treatment and prevention in the US, we examined three CDC-funded data sources in 2012: the HIV Outpatient Study (HOPS), a multisite longitudinal cohort; the Medical Monitoring Project (MMP), a probability sample of PLWH receiving medical care; and the National HIV Surveillance System (NHSS), a surveillance system of all PLWH. Overall, data from 1,697 HOPS, 4,901 MMP, and 865,102 NHSS PLWH were analyzed. Compared with the MMP population, HOPS participants were more likely to be older, non-Hispanic/Latino white, not using injection drugs, insured, diagnosed with HIV before 2009, prescribed antiretroviral therapy, and to have most recent CD4+ T-lymphocyte cell count ≥500 cells/mm3 and most recent viral load test<2 00 copies/mL. The MMP population was demographically similar to all PLWH in NHSS, except it tended to be slightly older, HIV diagnosed more recently, and to have AIDS. Our comparative results provide an essential first step for combined epidemiologic data analyses to inform HIV care and prevention for PLWH in the US. PMID:26793282

    The Caribbean is a multi-ethnic region with many different cultural differences. The majority of the population is of African descent, but there are also other ethnic groups present such as Indians, Chinese, Syrians and Europeans. The Caribbean region is influenced by countries such as the USA, Great Britain, France and Holland. The countries of the Caribbean have a serious problem with HIV infection and AIDS. The epidemiology of HIV infection in this region, is different from most other parts of the world in that the mode of spread does not easily fit into any of the three WHO patterns. This review shows that the infection initially started in the homosexual/bisexual community, but since then, it has moved to the heterosexual population and this form of contact is now the main mode of transmission of the virus. The Governments of the Caribbean countries have realized the extent of the problem and have taken measures to try to control the epidemic. PMID:8031923

    In 2007, an estimated 700,000 persons in China were living with human immunodeficiency virus (HIV) infection. An estimated 50,000 new HIV infections and 20,000 deaths related to acquired immunodeficiency syndrome (AIDS) occurred in 2007, and an estimated 71% of persons with HIV infection were unaware of their HIV status. In 2007, 40.6% of those living with HIV had been infected through heterosexual transmission and 38.1% through injection-drug use. Guangdong Province in southeastern China is the country's most populous province, with an estimated 75.6 million permanent residents and 16.5 million migrants; the province has undergone rapid economic development. Since 1986, a case-based surveillance system (CBSS) in China has collected data on persons infected with HIV, including demographic characteristics and transmission categories. To assess recent trends in HIV infection in the province, the Guangdong Center for Disease Control, with technical assistance from CDC, analyzed CBSS data for the period 1997--2007. The results of that analysis indicated that the number of HIV cases increased from 102 in 1997 to 4,593 in 2007, although this increase resulted, in part, from expanded testing and surveillance. Among males classified by HIV transmission category, 82.1% of newly diagnosed infections were attributed to injection-drug use. Among females classified by HIV transmission category, 53.7% engaged in high-risk heterosexual conduct. Despite substantial methodologic limitations, these results can be useful to Guangdong public health agencies in targeting and evaluating HIV prevention, care, and treatment programs. PMID:19390507

    HIV infection has been traditionally considered to be an absolute contraindication for solid organ transplantation. Recent advances in HIV treatment, as highly active antiretroviral therapy (HAART), significantly reduced HIV-related mortality and morbidity. At the same time the number of HIV-infected patients with end-stage organ diseases constantly increased. Current data describing solid organ transplantation in HIV-infected patients demonstrated comparable outcome to that in the HIV-negative population. In light of this, solid organ transplantation should be considered as a treatment option for selected HIV-positive patients with end-stage organ disease. PMID:15171000

    SUMMARY SETTING National Tuberculosis Treatment Centre, Mulago Hospital, Kampala, Uganda. OBJECTIVE To assess the efficacy of a daily, self-administered 8-month rifampicin-containing regimen for the treatment of pulmonary tuberculosis (TB) in human immunodeficiency virus (HIV) infected adults. DESIGN Treatment outcomes in patients with pulmonary TB treated with a single 8-month regimen and followed in a prospective epidemiological study. RESULTS Two hundred and sixty-five HIV-infected and 26 non-HIV-infected adults with initial episodes of pulmonary tuberculosis were treated with 2 months of daily isoniazid (INH), rifampicin (RMP), ethambutol and pyrazinamide followed by 6 months of daily INH + RMP. Median follow-up was 17.8 months. Ninety-five per cent of the HIV-infected and all of the non-HIV-infected patients who had sputum examined were sputum culture negative after 2 months of treatment. Twenty-two HIV-infected and no non-HIV-infected patients died during treatment. Relapse rates were 8.4% (5.9 per 100 person-years of observation [PYO], 95%CI 3.2–8.6) among HIV-infected patients and 4.5% (2.1/100 PYO, 95%CI 0–7.8) for non-HIV-infected patients. Adverse drug reactions occurred in 37% of the HIV-infected patients; most were minor and self-limiting. CONCLUSION An 8-month RMP-containing regimen was well tolerated and effective in the treatment of HIV-infected adults with initial episodes of pulmonary TB. Relapse rates were similar to those reported with 6-month short-course regimens in HIV-infected individuals. Decisions about the duration of anti-tuberculosis treatment for HIV-infected adults must balance programme resources and the likelihood of poor compliance with longer regimens with the potential for a modest decrease in relapses with longer treatment.

    In the absence of a cure, HIV-infected patients are being successfully treated with antiretroviral therapies (ART) and living longer. Indeed, an increasing number of HIV-infected patients are living beyond the age of 50 years, and in that regard, the use of ART has transformed HIV into a chronic medical condition. As more HIV-infected patients are virologically controlled and living longer, the trajectory of disease morbidity has shifted, however, primarily from opportunistic infections and immune dysfunction to metabolic complications. Evidence suggests that HIV-infected patients acquire significant metabolic risks, including lipodystrophic changes, subclinical atherosclerosis, and insulin resistance. The etiology of these metabolic complications specifically in HIV-infected patients is not entirely clear but may be related to a complex interaction between long-term consequences of infection and HIV itself, chronic use of antiretrovirals, and underlying inflammatory processes. Previous classes of ART, such as protease inhibitors (PIs) and reverse transcriptase inhibitors, have been implicated in altering fat redistribution and lipid and glucose homeostasis. Advances in drug development have introduced newer ART with strategies to target novel mechanisms of action and improve patient adherence with multi-class drug combinations. In this review, we will focus on these newer classes of ART, including selected entry inhibitors, integrase inhibitors, and multi-class drug combinations, and two newer PIs, and the potential of these newer agents to cause metabolic complications in HIV-infected patients. Taken together, further reduction of morbidity in HIV-infected patients will require increasing awareness of the deleterious metabolic complications of ART with subsequent management to mitigate these risks.

    Mitochondrial abnormalities may lead to metabolic complications in HIV-infected children who have been receiving long-term antiretroviral treatment. We conducted a matched, case-control study comparing 21 HIV-infected children with insulin resistance (cases) to 21 HIV-infected children without insulin resistance (controls) to assess differences in mitochondrial DNA (mtDNA) copies/cell and oxidative phosphorylation NADH dehydrogenase (C1) and cytochrome c oxidase (C4) enzyme activities in peripheral blood mononuclear cells. MtDNA copies/cell tended to be lower in cases, and fasting serum glucose levels were inversely and significantly correlated with C1 enzyme activity, more so in cases. Larger pediatric studies should evaluate mitochondrial etiologies of insulin resistance and determine the role of antiretroviral therapies or HIV infection on mitochondrial dysfunction.

    There is limited understanding of the epidemiology of meningitis among human immunodeficiency virus (HIV)-infected populations in sub-Saharan Africa. We conducted a prospective cohort study of HIV-infected adults with suspected meningitis in Uganda, to comprehensively evaluate the etiologies of meningitis. Intensive cerebrospiral fluid (CSF) testing was performed to evaluate for bacterial, viral, fungal, and mycobacterial etiologies, including neurosyphilis,16s ribosomal DNA (rDNA) polymerase chain reaction (PCR) for bacteria, Plex-ID broad viral assay, quantitative-PCR for HSV-1/2, cytomegalovirus (CMV), Epstein–Barr virus (EBV), and Toxoplasma gondii; reverse transcription-PCR (RT-PCR) for Enteroviruses and arboviruses, and Xpert MTB/RIF assay. Cryptococcal meningitis accounted for 60% (188 of 314) of all causes of meningitis. Of 117 samples sent for viral PCR, 36% were EBV positive. Among cryptococcal antigen negative patients, the yield of Xpert MTB/RIF assay was 22% (8 of 36). After exclusion of cryptococcosis and bacterial meningitis, 61% (43 of 71) with an abnormal CSF profile had no definitive diagnosis. Exploration of new TB diagnostics and diagnostic algorithms for evaluation of meningitis in resource-limited settings remains needed, and implementation of cryptococcal diagnostics is critical.

    The AIDS epidemic is still growing rapidly and the disease is thought to be uniformly fatal. With no vaccine or cure in sight, education during high school years is a critical component in the prevention of AIDS. We propose the use of computer software with which high school students can explore via simulation their own risk of acquiring an HIV infection given certain sexual behaviors. This particular software is intended to help students understand the three factors that determine their risk of HIV infection (number of sexual acts, probability that their partners are infected, and riskiness of the specific sexual activities they choose). Users can explicitly calculate their own chances of becoming infected based on decisions they make. Use of the program is expected to personalize the risk of HIV infection and thus increase users' concern and awareness. Behavioral change may not result from increased knowledge alone. Therefore the effectiveness of this program in changing attitudes toward risky sexual behaviors would be enhanced when the simulation is embedded in an appropriate curriculum. A description of the program and an example of its use are presented.

    Abstract The literature pertaining to the elderly shows that HIV infection among this population is on the increase, suggesting that the elderly population engages in activities risky for HIV infection. Reports on such behaviour include frequent sexual relations with much younger people and having multiple partners. A study was carried out in Ga-Rankuwa, a black township in Gauteng Province, South Africa to explore and describe the understanding of these elderly people regarding their risks of HIV infection and AIDS. Using a qualitative, exploratory design, three focus-group interviews were conducted with 32 women aged over 50 years. Findings revealed that older persons have knowledge about transmission of HIV infection and AIDS. However, a few had misconceptions as to how HIV infection is transmitted, as they believed that poor nutrition and sharing facilities play a role. Knowledge of mechanisms of protecting themselves against infection, such as use of a condom during coitus and wearing gloves when caring for infected family members, was also evident. The elderly indicated that they would prefer an older person, who they could identify with, to educate them more about HIV infection and AIDS. Although majority of participants had knowledge of how HIV is transmitted, and issues that put them at risk of transmission, a few the older persons had misconceptions about how HIV is transmitted due to lack of knowledge, as they believed that poor nutrition and sharing facilities can transmit infection. The lack of knowledge underscores the importance of addressing sexual risk with older people. It was very clear that more needs to be done in terms of education campaigns to dispel the myths of HIV infection and to empower the elderly. PMID:24957136

    The neurologic events related to antiretroviral therapy (ART) in HIV-infected ART-naive patients are relatively common. Side effects of ART and complications of HIV infection may overlap significantly. Establishing etiology of neurologic (neuropathy and neuropathic pain, changes in cognition, dementia, and myelopathy) and psychiatric (neurocognitive disorders, depression, anxiety, substance abuse and dependence, and others) complications can present a significant challenge. It has long been documented that neurologic and psychological side effects can occur with many of the agents used to treat HIV infection. Particularly, efavirenz from the non-nucleoside reverse transcriptase inhibitor (NNRTI) has been associated with neurologic and psychological complaints that may be difficult to differentiate from pre-existing mental illness, substance abuse, and HIV-related neuropsychiatric symptoms. Peripheral neuropathy (PN) of at least 6 different types is a well-known adverse effect of treatment with nucleoside reverse transcriptase inhibitors (NRTIs) in HIV-infected patients. Lack of dealing with early stages of neurologic and psychological side effects of HIV infection and Highly Active Anti-retroviral Therapy (HAART) are observed in daily practice. The purpose of this article is to identify the neurologic, neuropsychiatric and psychiatric complications related to HIV and anti-retroviral therapy, to discuss current knowledge about these disorders, and to suggest strategies for their diagnosis and management.

    Background Monitoring of the uptake and efficacy of ART in a population often relies on cross-sectional data, providing limited information that could be used to design specific targeted intervention programs. Using repeated measures of viral load (VL) surveillance data, we aimed to estimate and characterize the proportion of persons living with HIV/AIDS (PLWHA) in New York City (NYC) with sustained high VL (SHVL) and durably suppressed VL (DSVL). Methods/Principal Findings Retrospective cohort study of all persons reported to the NYC HIV Surveillance Registry who were alive and ≥12 years old by the end of 2005 and who had ≥2 VL tests in 2006 and 2007. SHVL and DSVL were defined as PLWHA with 2 consecutive VLs ≥100,000 copies/mL and PLWHA with all VLs ≤400 copies/mL, respectively. Logistic regression models using generalized estimating equations were used to model the association between SHVL and covariates. There were 56,836 PLWHA, of whom 7% had SHVL and 38% had DSVL. Compared to those without SHVL, persons with SHVL were more likely to be younger, black and have injection drug use (IDU) risk. PLWHA with SHVL were more likely to die by 2007 and be younger by nearly ten years, on average. Conclusions/Significance Nearly 60% of PLWHA in 2005 had multiple VLs, of whom almost 40% had DSVL, suggesting successful ART uptake. A small proportion had SHVL, representing groups known to have suboptimal engagement in care. This group should be targeted for additional outreach to reduce morbidity and secondary transmission. Measures based on longitudinal analyses of surveillance data in conjunction with cross-sectional measures such as community viral load represent more precise and powerful tools for monitoring ART effectiveness and potential impact on disease transmission than cross-sectional measures alone.

    Background Previous studies have used social network variables to improve our understanding of HIV transmission. Similar analytic approaches have not been undertaken for hepatitis C (HCV) or B (HBV), nor used to conduct comparative studies on these pathogens within a single setting. Methods A cross-sectional survey consisting of a questionnaire and blood sample was conducted on injection drug users in Winnipeg between December 2003 and September 2004. Logistic regression analyses were used to correlate respondent and personal network data with HCV, HBV and HIV prevalence. Results At the multivariate level, pathogen prevalence was correlated with both respondent and IDU risk network variables. Pathogen transmission was associated with several distinct types of high-risk networks formed around specific venues (shooting galleries, hotels) or within users who are linked by their drug use preferences. Smaller, isolated pockets of IDUs also appear to exist within the larger population where behavioural patterns pose a lesser risk, unless or until, a given pathogen enters those networks. Conclusion The findings suggest that consideration of both respondent and personal network variables can assist in understanding the transmission patterns of HCV, HBV, and HIV. It is important to assess these effects for multiple pathogens within one setting as the associations identified and the direction of those associations can differ between pathogens. PMID:16970811

    HIV+ persons with co-occurring bipolar disorder (HIV+/BD+) have elevated rates of medication nonadherence. We conducted a 30-day randomized controlled trial of a two-way, text messaging system, iTAB (n = 25), compared to an active comparison (CTRL) (n = 25) to improve antiretroviral (ARV) and psychotropic (PSY) adherence and dose timing. Both groups received medication adherence psychoeducation and daily texts assessing mood. The iTAB group additionally received personalized medication reminder texts. Participants responded to over 90 % of the mood and adherence text messages. Mean adherence, as assessed via electronic monitoring caps, was high and comparable between groups for both ARV (iTAB 86.2 % vs. CTRL 84.8 %; p = 0.95, Cliff’s d = 0.01) and PSY (iTAB 78.9 % vs. CTRL 77.3 %; p = 0.43, Cliff’s d = −0.13) medications. However, iTAB participants took ARVs significantly closer to their intended dosing time than CTRL participants (iTAB: 27.8 vs. CTRL: 77.0 min from target time; p = 0.02, Cliff’s d = 0.37). There was no group difference on PSY dose timing. Text messaging interventions may represent a low-burden approach to improving timeliness of medication-taking behaviors among difficult-to-treat populations. The benefits of improved dose timing for long-term medication adherence require additional investigation. PMID:25504449

    Mycobacterial infections have caused enormous morbidity and mortality in people living with human immunodeficiency virus (HIV) infection. Of these, the most devastating has been tuberculosis (TB), the leading cause of death among HIV-positive persons globally. TB has killed more people living with HIV than any other infection. Diagnosis of latent TB infection (LTBI) is critical as treatment can prevent emergence of TB disease. Bacteriologic confirmation of TB disease should be sought whenever possible as well as drug susceptibility testing. When detected early, drug susceptible TB is curable. Similar to TB, nontuberculous mycobacteria (NTM) can also produce pulmonary and extrapulmonary infections including disseminated disease that can be fatal. Diagnosis through accurate identification of the pathogenic organism will greatly inform treatment. Depending on the NTM identified, treatment may not be curable. Ultimately, preventive strategies such as initiation of antiretroviral drugs and treatment of LTBI are interventions expected to have significant impacts on control of TB and NTM in the setting of HIV. This chapter will review the impact of pulmonary mycobacterial infections on HIV-positive individuals. PMID:26974300

    The effects of HIV-1 in the nervous system are a topic of avid interest to investigators and clinicians focused on HIV, judging by the large and discriminating audience at the oral sessions and poster presentations relating to neuroscience at the 19th Conference on Retroviruses and Opportunistic Infections. Major areas of investigation at this year's conference included the use of neuropsychological testing and neuroimaging to assess the state of the central nervous system (CNS) and effects of antiretroviral therapy during HIV infection as well as basic and clinical studies of neuropathogenesis of HIV-associated neurocognitive disorder (HAND). Numerous important suggestions emerged during the meeting. Among them was the proposition that earlier initiation of therapy might benefit the CNS. Another was that the relationship between HIV and normal aging remains unclear and warrants further study. Still another was that ongoing abnormalities may persist despite treatment with antiretroviral therapy-including measurable brain microglial activation, detectable cerebrospinal fluid HIV, and progression of neurologic impairment.

    In Europe depending on the country 15-80 % of all individuals infected with human immunodeficiency virus (HIV) are either not aware of the diagnosis or are diagnosed later. An early HIV diagnosis could, however, considerably improve the prognosis of individuals infected with HIV and decrease the risk of new infections; therefore, in the presence of indicator diseases, such as sexually transmitted diseases, oral thrush, herpes zoster and lymphoma, the performance of a HIV test is of utmost importance. A newly diagnosed HIV infection represents an indication for starting antiretroviral combination therapy independent of the clinical stage or CD4 cell count. A decline of the viral burden to below the limit of detection and subsequent continuous suppression of viral replication can prevent transition from HIV to acquired immune deficiency syndrome (AIDS) and if started early enough a normal life expectancy can be achieved. Challenges which remain in HIV therapy are the lifelong daily intake of medication and the complex long-term adverse effects. PMID:27368530

    The epidemiology, clinical features, and drug treatment of depression in HIV-infected patients are discussed. The lifetime prevalence of depression in patients infected with HIV has been estimated at 22-45%. The signs and symptoms of depression are similar in HIV-infected and noninfected patients, but patients with HIV infection may more frequently have sleep and appetite disturbances. Diagnosis should focus on affective or cognitive depression symptoms that reflect mood state alone. Patients with a history of depression, homosexual men, women, and i.v. drug abusers are among HIV-infected individuals who may be at increased risk for depression. Depression may alter the course of HIV infection by impairing immune function or influencing behavior. Depression my contribute to nonadherence to therapy. Antidepressant therapy is effective in most HIV-positive patients with major depression. Tricyclic antidepressants (TCAs) have produced response rates as high as 89%, but their usefulness has been limited by adverse effects. Selective serotonin-reuptake inhibitors and other non-TCAs have also demonstrated efficacy and are generally better tolerated. Psychostimulants have improved mood, cognition, and energy level, and androgens have been used for their anabolic effects. The systemic concentrations of antidepressants may be altered by coadministered drugs that affect their cytochrome P-450 isoenzyme-mediated metabolism; in turn, the metabolism and toxicity of certain antiretrovirals may be affected by antidepressants. Guidelines on the treatment of depression in the general population may be applied to patients with HIV infection. Depressive disorders are prevalent among patients with HIV infection but often respond to a variety of treatments. PMID:10714976

    OBJECTIVE: To assess the frequency of shedding of polyomavirus JC virus (JCV) genotypes in urine of HIV-infected patients receiving highly active antiretroviral therapy (HAART). METHODS: Single samples of urine and blood were collected prospectively from 70 adult HIV-infected patients and 68 uninfected volunteers. Inclusion criteria for HIV-infected patients included an HIV RNA viral load < 1000 copies, CD4 cell count of 200-700 x 106 cells/l, and stable HAART regimen. PCR assays and sequence analysis were carried out using JCV-specific primers against different regions of the virus genome. RESULTS: JCV excretion in urine was more common in HIV-positive patients but not significantly different from that of the HIV-negative group [22/70 (31%) versus 13/68 (19%); P = 0.09]. HIV-positive patients lost the age-related pattern of JCV shedding (P = 0.13) displayed by uninfected subjects (P = 0.01). Among HIV-infected patients significant differences in JCV shedding were related to CD4 cell counts (P = 0.03). Sequence analysis of the JCV regulatory region from both HIV-infected patients and uninfected volunteers revealed all to be JCV archetypal strains. JCV genotypes 1 (36%) and 4 (36%) were the most common among HIV-infected patients, whereas type 2 (77%) was the most frequently detected among HIV-uninfected volunteers. CONCLUSION: These results suggest that JCV shedding is enhanced by modest depressions in immune function during HIV infection. JCV shedding occurred in younger HIV-positive persons than in the healthy controls. As the common types of JCV excreted varied among ethnic groups, JCV genotypes associated with progressive multifocal leukoencephalopathy may reflect demographics of those infected patient populations.

    The brain remains a major target for HIV infection and a site of potential complications for HIV-infected individuals. Emerging data presented at the 2016 Conference on Retroviruses and Opportunistic Infections suggest that during the early stages of infection, activated CD4+ cells may traffic the virus into the central nervous system (CNS). HIV is detectable in cells and tissues of the CNS in some individuals despite suppressive antiretroviral treatment. A potential source of cerebrospinal fluid HIV escape may be compartmentalized HIV replication within macrophage lineage cells. Virally infected cells can traffic out of the CNS and may have the potential to reseed the systemic compartment. Additional modifiers of HIV-associated neurocognitive disorder (HAND) were identified, including female sex and hepatic dysfunction. Large epidemiologic studies reported an elevated risk of stroke among HIV-infected individuals, related to traditional vascular risk factors, history of recreational drug use, and HIV measures (lower CD4+ cell nadir and higher viral load). Brain imaging may provide a noninvasive means for detecting early changes in the brain associated with HIV infection and may assist in prognosis of HAND. Some potential adjunctive therapies to standard antiretroviral therapy for HIV-infected individuals were considered. PMID:27398860

    Objectives Rates of first-line treatment failure and switches to second-line therapy are key indicators for national HIV programmes. We assessed immunological treatment failure defined by WHO criteria in the Tanzanian national HIV programme. Methods We included adults initiating first-line therapy in 2004–2011 with a pre-treatment CD4 count, and ≥6-months of follow-up. We assessed subhazard ratios (SHR) for immunological treatment failure, and subsequent switch to second-line therapy, using competing risks methods to account for deaths. Results Of 121 308 adults, 7% experienced immunological treatment failure, and 2% died without observed immunological treatment failure, over a median 1.7 years. The 6-year cumulative probability of immunological treatment failure was 19.0% (95% CI 18.5, 19.7) and of death, 5.1% (4.8, 5.4). Immunological treatment failure predictors included earlier year of treatment initiation (P < 0.001), initiation in lower level facilities (SHR = 2.23 [2.03, 2.45] for dispensaries vs. hospitals), being male (1.27 [1.19, 1.33]) and initiation at low or high CD4 counts (for example, 1.78 [1.65, 1.92] and 5.33 [4.65, 6.10] for <50 and ≥500 vs. 200–349 cells/mm3, respectively). Of 7382 participants in the time-to-switch analysis, 6% switched and 5% died before switching. Four years after immunological treatment failure, the cumulative probability of switching was 7.3% (6.6, 8.0) and of death, 6.8% (6.0, 7.6). Those who immunologically failed in dispensaries, health centres and government facilities were least likely to switch. Conclusions Immunological treatment failure rates and unmet need for second-line therapy are high in Tanzania; virological monitoring, at least for persons with immunological treatment failure, is required to minimise unnecessary switches to second-line therapy. Lower level government health facilities need more support to reduce treatment failure rates and improve second-line therapy uptake to sustain the

    Background. Anal cancer is one of the most common cancers affecting individuals infected with human immunodeficiency virus (HIV), although few have evaluated rates separately for men who have sex with men (MSM), other men, and women. There are also conflicting data regarding calendar trends. Methods. In a study involving 13 cohorts from North America with follow-up between 1996 and 2007, we compared anal cancer incidence rates among 34 189 HIV-infected (55% MSM, 19% other men, 26% women) and 114 260 HIV-uninfected individuals (90% men). Results. Among men, the unadjusted anal cancer incidence rates per 100 000 person-years were 131 for HIV-infected MSM, 46 for other HIV-infected men, and 2 for HIV-uninfected men, corresponding to demographically adjusted rate ratios (RRs) of 80.3 (95% confidence interval [CI], 42.7–151.1) for HIV-infected MSM and 26.7 (95% CI, 11.5–61.7) for other HIV-infected men compared with HIV-uninfected men. HIV-infected women had an anal cancer rate of 30/100 000 person-years, and no cases were observed for HIV-uninfected women. In a multivariable Poisson regression model, among HIV-infected individuals, the risk was higher for MSM compared with other men (RR, 3.3; 95% CI, 1.8–6.0), but no difference was observed comparing women with other men (RR, 1.0; 95% CI, 0.5–2.2). In comparison with the period 2000–2003, HIV-infected individuals had an adjusted RR of 0.5 (95% CI, .3–.9) in 1996–1999 and 0.9 (95% CI, .6–1.2) in 2004–2007. Conclusions. Anal cancer rates were substantially higher for HIV-infected MSM, other men, and women compared with HIV-uninfected individuals, suggesting a need for universal prevention efforts. Rates increased after the early antiretroviral therapy era and then plateaued. PMID:22291097

    Androgen deficiency occurs frequently in men with human immunodeficiency virus (HIV) infection. Antiretroviral treatments had reduced the prevalence of male hypogonadism. The pathogenesis of testosterone (T) deficiency in HIV is multifactorial. Several mechanisms have been proposed; among them, drugs, fat redistribution, and a poor health status could explain the mechanism leading to gonadotropins inhibition and hypogonadotropic hypogonadism. The diagnosis of hypogonadism in HIV-infected men should be made based on clinical symptoms and a specific workup including T measurement. The interpretation of the results of biochemical testing is more difficult in men with HIV due to several confounding factors. T treatment should be offered to HIV-infected men with documented clinical hypogonadism and symptoms, especially if they are losing lean mass. PMID:25169563

    2013-01-01

    Racial/ethnic disparities in HIV infection, with minority groups typically having higher rates of infection, are a formidable public health challenge. In the United States, among both men and women who inject drugs, HIV infection rates are elevated among non-Hispanic Blacks and Hispanics. A meta-analysis of international research concluded that among persons who inject drugs, racial and ethnic minorities were twice as likely to acquire an HIV infection, though there was great variation across the individual studies. To examine strategies to reduce racial/ethnic disparities among persons who inject drugs, we reviewed studies on injection drug use and its role in HIV transmission. We identified four sets of evidence-based interventions that may reduce racial ethnic disparities among persons who inject drugs: HIV counseling and testing, risk reduction services, access to anti-retroviral therapy, and drug abuse treatment. Implementation of these services, however, is insufficient in many countries, including the US. Persons who inject drugs appear to be changing drug use norms and rituals to reduce risks. The challenges are to 1) develop a validated model of how racial/ethnic disparities in HIV infection arise, persist, and are reduced or eliminated over time, and 2) implement evidence-based services on a sufficient scale to eliminate HIV transmission among all persons who inject drugs.

    Antiretroviral therapy has significantly improved the life expectancy in HIV-infected people, but it cannot cure the disease by itself. Several barriers have been identified for the cure of HIV infection, including a reservoir of latently infected cells, persistent viral replication in tissues, and anatomical sanctuaries. The main strategy proposed for the cure of HIV consists on the administration of drugs that, through the reactivation of latent HIV, would eliminate the cell reservoir. Ongoing clinical trials have shown the proof of concept, but the efficacy of these drugs in decreasing the reservoir size has not been proved so far. PMID:26365737

    There has recently been a resurgence of interest in the gastrointestinal pathology observed in patients infected with HIV. The gastrointestinal tract is a major site of HIV replication, which results in massive depletion of lamina propria CD4 T cells during acute infection. Highly active antiretroviral therapy leads to incomplete suppression of viral replication and substantially delayed and only partial restoration of gastrointestinal CD4 T cells. The gastrointestinal pathology associated with HIV infection comprises significant enteropathy with increased levels of inflammation and decreased levels of mucosal repair and regeneration. Assessment of gut mucosal immune system has provided novel directions for therapeutic interventions that modify the consequences of acute HIV infection. PMID:19079157

    Patients presenting with fever, pharyngitis, and lymphadenopathy are likely to have mononucleosis; however, patients with acute HIV infection may present with similar symptoms. Acute HIV infection should be considered as a differential diagnosis if test results for mononucleosis are negative. This article describes when to order HIV testing and discusses the importance of early intervention for acute HIV infection. PMID:26678418

    The development of gonococcal arthritis is reported in a man with HIV infection and CDC Stage IVC2 disease. The diagnosis of disseminated Neisseria gonorrhoeae was facilitated by microbiological examination of a joint aspirate. The auxotype identified by culture was moderately resistant to penicillin, a characteristic which is highly unusual for an organism causing disseminated gonococcal infection. This case serves as an example of the role of HIV infection in the modification of host response to common pathogens and the need for clinicians to modify their management of disseminated gonococcal infection especially in immunosuppressed persons.

    BACKGROUND Preexposure prophylaxis with antiretroviral drugs has been effective in the prevention of human immunodeficiency virus (HIV) infection in some trials but not in others. METHODS In this randomized, double-blind, placebo-controlled trial, we assigned 2120 HIV-negative women in Kenya, South Africa, and Tanzania to receive either a combination of tenofovir disoproxil fumarate and emtricitabine (TDF–FTC) or placebo once daily. The primary objective was to assess the effectiveness of TDF–FTC in preventing HIV acquisition and to evaluate safety. RESULTS HIV infections occurred in 33 women in the TDF–FTC group (incidence rate, 4.7 per 100 person-years) and in 35 in the placebo group (incidence rate, 5.0 per 100 person-years), for an estimated hazard ratio in the TDF-FTC group of 0.94 (95% confidence interval, 0.59 to 1.52; P = 0.81). The proportions of women with nausea, vomiting, or elevated alanine aminotransferase levels were significantly higher in the TDF–FTC group (P = 0.04, P<0.001, and P = 0.03, respectively). Rates of drug discontinuation because of hepatic or renal abnormalities were higher in the TDF–FTC group (4.7%) than in the placebo group (3.0%, P = 0.051). Less than 40% of the HIV-uninfected women in the TDF–FTC group had evidence of recent pill use at visits that were matched to the HIV-infection window for women with seroconversion. The study was stopped early, on April 18, 2011, because of lack of efficacy. CONCLUSIONS Prophylaxis with TDF–FTC did not significantly reduce the rate of HIV infection and was associated with increased rates of side effects, as compared with placebo. Despite substantial counseling efforts, drug adherence appeared to be low. (Supported by the U.S. Agency for International Development and others; FEM-PrEP ClinicalTrials.gov number, NCT00625404.)

    Background. Human immunodeficiency virus (HIV)-infected adults, particularly those of black race, are at high-risk for end-stage renal disease (ESRD), but contributing factors are evolving. We hypothesized that improvements in HIV treatment have led to declines in risk of ESRD, particularly among HIV-infected blacks. Methods. Using data from the North American AIDS Cohort Collaboration for Research and Design from January 2000 to December 2009, we validated 286 incident ESRD cases using abstracted medical evidence of dialysis (lasting >6 months) or renal transplant. A total of 38 354 HIV-infected adults aged 18–80 years contributed 159 825 person-years (PYs). Age- and sex-standardized incidence ratios (SIRs) were estimated by race. Poisson regression was used to identify predictors of ESRD. Results. HIV-infected ESRD cases were more likely to be of black race, have diabetes mellitus or hypertension, inject drugs, and/or have a prior AIDS-defining illness. The overall SIR was 3.2 (95% confidence interval [CI], 2.8–3.6) but was significantly higher among black patients (4.5 [95% CI, 3.9–5.2]). ESRD incidence declined from 532 to 303 per 100 000 PYs and 138 to 34 per 100 000 PYs over the time period for blacks and nonblacks, respectively, coincident with notable increases in both the prevalence of viral suppression and the prevalence of ESRD risk factors including diabetes mellitus, hypertension, and hepatitis C virus coinfection. Conclusions. The risk of ESRD remains high among HIV-infected individuals in care but is declining with improvements in virologic suppression. HIV-infected black persons continue to comprise the majority of cases, as a result of higher viral loads, comorbidities, and genetic susceptibility. PMID:25409471

    OBJECTIVES. Understanding more about the psychological state of persons notified of human immunodeficiency virus (HIV) infection is critical for designing notification and counseling programs that will have the most positive effect. METHODS. The subjects were blood donors who had been notified of HIV infection by the New York Blood Center. A nurse elicited a medical history, performed a limited medical examination, and asked the subjects to complete a questionnaire that included questions about drug use, sexual behavior, and psychological characteristics. The subjects completed another questionnaire approximately 2 weeks later. RESULTS. The average depressive symptom scores for both men and women were substantially higher than scores typically found in representative population samples. More than a quarter of the men and more than a third of the women reported seeking psychological or psychiatric services in the first few weeks following notification. CONCLUSIONS. Anticipating and meeting individuals' psychological needs may be necessary if HIV screening programs are to address effectively the needs of persons infected with HIV. PMID:8460730

    Background Risky decision-making is commonly observed in persons at risk for and infected with HIV and is associated with executive dysfunction. Yet it is currently unknown whether HIV alters brain processing of risk-taking decision-making. Methods This study examined the neural substrate of a risky decision-making task in 21 HIV seropositive (HIV+) and 19 seronegative (HIV-) comparison participants. Functional magnetic resonance imaging was conducted while participants performed the risky-gains task, which involves choosing among safe (20 cents) and risky (40/80 cent win or loss) choices. Linear mixed effects analyses examining group and decision type were conducted. Robust regressions were performed to examine the relationship between nadir CD4 count and Kalichman sexual compulsivity and brain activation in the HIV+ group. The overlap between the task effects and robust regressions was explored. Results Although there were no serostatus effects in behavioral performance on the risky-gains task, HIV+ individuals exhibited greater activation for risky choices in the basal ganglia, i.e. the caudate nucleus, but also in the anterior cingulate, dorsolateral prefrontal cortex, and insula relative to the HIV- group. The HIV+ group also demonstrated reduced functional responses to safe choices in the anterior cingulate and dorsolateral prefrontal cortex relative to the HIV- group. HIV+ individuals with higher nadir CD4 count and greater sexual compulsivity displayed lower differential responses to safe versus risky choices in many of these regions. Conclusions This study demonstrated fronto-striatal loop dysfunction associated with HIV infection during risky decision-making. Combined with similar between-group task behavior, this suggests an adaptive functional response in regions critical to reward and behavioral control in the HIV+ group. HIV-infected individuals with higher CD4 nadirs demonstrated activation patterns more similar to seronegative individuals. This

    Invasive anal cancer has become an important cause of non AIDS-related cancer among HIV-infected individuals. Human papillomavirus is the main etiological agent. This review explains the pathophysiologic role of human papillomavirus in the development of invasive anal cancer, summarizes recent epidemiological trends of invasive anal cancer, and reviews the evidence to address common clinical questions posed when screening for anal cancer in HIV-infected patients. The effect of highly active antiretroviral therapy on human papillomavirus oncogenesis is still unclear, but given the increased clinical burden of invasive anal cancer among HIV-infected patients, many clinics have implemented screening programs for anal cancer and its precursors. Despite the availability of several modalities for treatment of precursors of anal cancer, evidence that current treatment modalities favorably alter the natural history of human papillomavirus oncogenesis in the anal and perianal regions is still inconclusive. However, there is sufficient evidence to state that the accuracy of anal cancer screening procedures (cytology and high-resolution anoscopy directed biopsy) is comparable to the accuracy of those used in screening for cervical cancer precursors. Studies that systematically assess the efficacy of these anal cancer screening programs in reducing the incidence of and morbidity and mortality from invasive anal cancer among HIV-infected patients are needed.

    The course of HIV infection has changed dramatically since the beginning of the epidemic. In Germany, 19 antiretrovirally active substances are available. They prevent viral penetration into the cell, inhibit the reverse transcriptase or the protease that are necessary to release infectious viral particles. According to German-Austrian therapy guidelines highly active antiretroviral therapy (HAART) should be started at the onset of HIV-related symptoms and/or when the CD4 cell count is < 350/microl. Patients should be treated in specialized centers because of the complexity of HIV infection and its management. For monitoring, CD4 cell counts and viral load are determined. Potential reasons for therapeutic failure include drug interactions, resistance, or compliance problems. Although HIV infection is often compared to insulin-dependent diabetes mellitus, psychological and social impact on HIV patients is still high. Increasing viral multi-drug resistance, long-term toxicity like lipodystrophy, osteoporosis and cardiovascular disease are only some problems HIV-infected patients are facing in the next years. In Germany, 600-700 patients still die of AIDS every year. PMID:16170674

    Access to high-quality reproductive health care is important for adolescents and young adults with HIV infection to prevent unintended pregnancies, sexually transmitted infections, and secondary transmission of HIV to partners and children. As perinatally HIV-infected children mature into adolescence and adulthood and new HIV infections among adolescents and young adults continue to occur in the United States, medical providers taking care of such individuals often face issues related to sexual and reproductive health. Challenges including drug interactions between several hormonal methods and antiretroviral agents make decisions regarding contraceptive options more complex for these adolescents. Dual protection, defined as the use of an effective contraceptive along with condoms, should be central to ongoing discussions with HIV-infected young women and couples wishing to avoid pregnancy. Last, reproductive health discussions need to be integrated with discussions on HIV care, because a reduction in plasma HIV viral load below the level of detection (an "undetectable viral load") is essential for the individual's health as well as for a reduction in HIV transmission to partners and children.

    The AIDS epidemic has spread rapidly in Africa among the urban impoverished where multiple sexual partners and sexually transmitted diseases are common. Over 80% of the 9 million Africans who will develop AIDS before the year 2000 will have been contaminated sexually. Poverty, multiple sexual partners in the framework of prostitution, and drug addiction are responsible for rapid spread of HIV infection in Southeast Asia, the West India, and Brazil. Drug addiction has played a major role in diffusion of HIV into the general population of Europe and the US. Prevalence rates are much higher in sexually transmitted disease centers in France and the US than among blood donors or pregnant women. Sexually transmitted diseases and heterosexual transmission have been studied in Africas since diagnostic tests became available. Several studies, the majority conducted among prostitutes in Nairobi or Kinshasa and their clients, allow establishment of a list of sexually transmitted diseases associated with increased risk of seroconversion. Genital ulcers within the past 6 months presented a relative risk of 2-4 depending on the series. Urethral or cervical gonorrhea has a lower relative risk of 1.2 in most studies. Absence of circumcision was also a risk factor. Studies were subsequently conducted in Europe on factors favoring sexual transmission. 513 heterosexual couples together for a minimum duration of 18 months and an average of 38 months were included in the Multicenter European Study conducted in 10 centers in 9 countries. The "index" subject was male in 400 cases and female in 113. At entry into the study, 73 of 400 males (18.2%) and 10 of 113 females (8.8%) had already infected their partners. Duration of union, frequency of intercourse, mode of transmission of the index subject, and oral contraceptive use had no effect on risk of transmission. Factors increasing risk of infection included the severity of immunosuppression of the index subject, whether judged by

    2015-12-01

    Problem gambling is a significant mental health problem that creates a multitude of intrapersonal, interpersonal, and social difficulties. Recent empirical evidence suggests that personality disorders, and in particular borderline personality disorder (BPD), are commonly co-morbid with problem gambling. Despite this finding there has been very little research examining overlapping factors between these two disorders. The aim of this review is to summarise the literature exploring the relationship between problem gambling and personality disorders. The co-morbidity of personality disorders, particularly BPD, is reviewed and the characteristics of problem gamblers with co-morbid personality disorders are explored. An etiological model from the more advanced BPD literature-the biosocial developmental model of BPD-is used to review the similarities between problem gambling and BPD across four domains: early parent-child interactions, emotion regulation, co-morbid psychopathology and negative outcomes. It was concluded that personality disorders, in particular BPD are commonly co-morbid among problem gamblers and the presence of a personality disorder complicates the clinical picture. Furthermore BPD and problem gambling share similarities across the biosocial developmental model of BPD. Therefore clinicians working with problem gamblers should incorporate routine screening for personality disorders and pay careful attention to the therapeutic alliance, client motivations and therapeutic boundaries. Furthermore adjustments to therapy structure, goals and outcomes may be required. Directions for future research include further research into the applicability of the biosocial developmental model of BPD to problem gambling. PMID:25373399

    This thesis is based on seven previously published articles. The work was performed during my employment at The Department of Infectious Diseases, Copenhagen University Hospital, Hvidovre, as a scholarship student from 2000-2001 and as a research assistant in the period 2004-2010. HIV-infection is characterized by CD4+ cell depletion. The differences between patients in the degree of CD4+ cell recovery upon treatment with highly active antiretroviral therapy (HAART) may in part be due to differences in the supply of naïve CD4+ cells from the thymus. The thymus atrophies with increasing age for which reason the adult thymus was previously assumed to be without function. The aim of these investigations was to examine the role of the thymus in different aspects of HIV-infection: In adult HIV-infected patients, during HIV-positive pregnancy, and in HIV-exposed uninfected (HIV-EU) children born to HIV-infected mothers. Thymic size and output were determined in 25 adult HIV-infected patients receiving HAART and in 10 controls. Larger thymic size was associated with higher CD4 counts and higher thymic output. Furthermore, patients with abundant thymic tissue seemed to have broader immunological repertoires, compared with patients with minimal thymic tissue. The study supports the mounting evidence of a contribution by the adult thymus to immune reconstitution in HIV-infection. In a follow-up study conducted till 5 years of HAART, the importance of the thymus to the rate of cellular restoration was found to primarily lie within the first two years of HAART. The effect of recombinant human growth hormone (rhGH) was then investigated in a randomized, double-blinded placebo controlled trial in 46 adult HIV-infected patients on HAART. Daily treatment with a low dose of rhGH of 0.7mg for 40 weeks stimulated thymopoiesis as expressed by thymic size, density, and output strongly supporting the assumption that rhGH possesses the potential to stimulate the ageing thymus, holding

    BACKGROUND Treatment of latent tuberculosis in patients infected with the human immunodeficiency virus (HIV) is efficacious, but few patients around the world receive such treatment. We evaluated three new regimens for latent tuberculosis that may be more potent and durable than standard isoniazid treatment. METHODS We randomly assigned South African adults with HIV infection and a positive tuberculin skin test who were not taking antiretroviral therapy to receive rifapentine (900 mg) plus isoniazid (900 mg) weekly for 12 weeks, rifampin (600 mg) plus isoniazid (900 mg) twice weekly for 12 weeks, isoniazid (300 mg) daily for up to 6 years (continuous isoniazid), or isoniazid (300 mg) daily for 6 months (control group). The primary end point was tuberculosis-free survival. RESULTS The 1148 patients had a median age of 30 years and a median CD4 cell count of 484 per cubic millimeter. Incidence rates of active tuberculosis or death were 3.1 per 100 person-years in the rifapentine–isoniazid group, 2.9 per 100 person-years in the rifampin–isoniazid group, and 2.7 per 100 person-years in the continuous-isoniazid group, as compared with 3.6 per 100 person-years in the control group (P>0.05 for all comparisons). Serious adverse reactions were more common in the continuous-isoniazid group (18.4 per 100 person-years) than in the other treatment groups (8.7 to 15.4 per 100 person-years). Two of 58 isolates of Mycobacterium tuberculosis (3.4%) were found to have multidrug resistance. CONCLUSIONS On the basis of the expected rates of tuberculosis in this population of HIV-infected adults, all secondary prophylactic regimens were effective. Neither a 3-month course of intermittent rifapentine or rifampin with isoniazid nor continuous isoniazid was superior to 6 months of isoniazid. PMID:21732833

    The consequences of the HIV epidemic on cancer epidemiology are sparsely documented in Africa. We aimed to estimate the association between HIV infection and selected types of cancers among patients hospitalized for cancer in four West African countries. A case-referent study was conducted in referral hospitals of Benin, Côte d'Ivoire, Nigeria and Togo. Each participating clinical ward included all adult patients seeking care with a confirmed diagnosis of cancer. All patients were systematically screened for HIV infection. HIV prevalence of AIDS-defining and some non-AIDS defining cancers (Hodgkin lymphoma, leukemia, liver, lung, skin, pharynx, larynx, oral cavity and anogenital cancers) were compared to a referent group of cancers reported in the literature as not associated with HIV. Odds ratios adjusted on age, gender and lifetime number of sexual partners (aOR) and their 95% confidence intervals (CI) were estimated. Among the 1644 cancer patients enrolled, 184 (11.2%) were identified as HIV-infected. The HIV prevalence in the referent group (n=792) was 4.4% [CI 3.0-5.8]. HIV infection was associated with Kaposi sarcoma (aOR 34.6 [CI: 17.3-69.0]), non-Hodgkin lymphoma (aOR 3.6 [CI 1.9-6.8]), cervical cancer (aOR 4.3 [CI 2.2-8.3]), anogenital cancer (aOR 17.7 [CI 6.9-45.2]) and squamous cell skin carcinoma (aOR 5.2 [CI 2.0-14.4]). A strong association is now reported between HIV infection and Human Papillomavirus (HPV)-related cancers including cervical cancer and anogenital cancer. As these cancers are amenable to prevention strategies, screening of HPV-related cancers among HIV-infected persons is of paramount importance in this African context. PMID:26375806

    It has been reported that borderline personality related characteristics can be observed in children, and that these characteristics are associated with increased risk for the development of borderline personality disorder. It is not clear whether borderline personality related characteristics in children share etiological features with adult borderline personality disorder. We investigated the etiology of borderline personality related characteristics in a longitudinal cohort study of 1,116 pairs of same-sex twins followed from birth through age 12 years. Borderline personality related characteristics measured at age 12 years were highly heritable, were more common in children who had exhibited poor cognitive function, impulsivity, and more behavioral and emotional problems at age 5 years, and co-occurred with symptoms of conduct disorder, depression, anxiety, and psychosis. Exposure to harsh treatment in the family environment through age 10 years predicted borderline personality related characteristics at age 12 years. This association showed evidence of environmental mediation and was stronger among children with a family history of psychiatric illness, consistent with diathesis–stress models of borderline etiology. Results indicate that borderline personality related characteristics in children share etiological features with borderline personality disorder in adults and suggest that inherited and environmental risk factors make independent and interactive contributions to borderline etiology.

    Purpose of review Detection of early HIV infections (EHIs), including acute HIV infection (AHI), is important for individual health, prevention of HIV transmission, and measurement of HIV incidence. We describe markers of EHI, diagnostic strategies for detecting these markers, and ways to incorporate these strategies into diagnostic and HIV incidence algorithms. Recent findings For individual diagnosis in the United States and Europe, laboratory-based diagnostic algorithms increasingly incorporate fourth-generation HIV antigen tests, allowing for earlier detection. In some sub-Saharan African settings, symptom-based screening is being explored to identify subsets of persons at high risk for AHI. Point-of-care diagnostics designed for AHI detection are in the pipeline and, if validated, represent an opportunity for real-time AHI diagnosis. At the population level, multiassay algorithms are promising new strategies for estimating HIV incidence on the basis of several assays applied to cross-sectional samples. These algorithms can be developed to optimize performance, in addition to cost and logistical considerations. Summary There are important recent advances in detection of EHIs at the individual and population levels. Applying optimal combinations of tests in diagnostic and HIV incidence algorithms is urgently needed to support the multiple goals derived from enhanced detection and discrimination of EHIs.

    1996-01-01

    The advent of AIDS has had such a deep-reaching effect on the international haemophilia community that one can make a reasonable distinction between a pre-AIDS and a post-AIDS era in haemophilia management. In the context of counselling, however, talking about a 'before' and an 'after' in haemophilia does not (and, in our opinion, should not) necessarily imply a separation of the past from the present. Dealing with the psycho-social implications of haemophilia and HIV infection does not mean focusing exclusively on HIV-generated problems at the expense of haemophilia-related issues. Since the HIV crisis, counselling has posed the multiple challenge of: (a) assessing and alleviating the more immediate emotional effects of HIV infection; (b) paying due attention to the underlying influence of haemophilia on reaction, defence and coping; (c) formulating a flexible approach that is based on close cooperation with the medical staff and effective interpersonal communication with the counsellees.* In practice, the flexibility and effectiveness of the counselling model are promoted by means of: (a) ongoing counselling, (b) multiple counselling sites (i.e. the Haemophilia Centre and other appropriate locations), (c) interdisciplinary team-work, (d) respect for individual/ ethnic values, (e) maintenance of exo-empathy (i.e. neutrality), and (f) transfer of coping skills. The above framework can help maximize the effectiveness of counselling sessions through a personalized rapport of mutual trust and confidence between the counselling team and the counsellees.

    Highly active antiretroviral therapy (HAART) has had a significant impact on the natural history of human immunodeficiency virus (HIV) infection, leading to a remarkable decrease in its morbidity and mortality, but is frequently associated with clinical and metabolic complications. Fat redistribution or lipodystrophy, hypertriglyceridaemia, hypercholesterolaemia, insulin resistance and diabetes mellitus have been extensively reported in subjects treated with protease inhibitor (PI)-based antiretroviral regimens. In particular, dyslipidaemia occurs in up to 70-80% of HIV-infected individuals receiving HAART and can be associated with all the available PIs, although hypertriglyceridaemia appears to be more frequent in patients treated with ritonavir, ritonavir-saquinavir, or ritonavir-lopinavir. The potential long-term consequences of HAART-associated hyperlipidaemia are not completely understood, but an increased risk of premature coronary artery disease has been reported in young HIV-positive persons receiving PIs. Dietary changes, regular aerobic exercise and switching to a PI-sparing regimen may act favourably on dyslipidaemia. Lipid-lowering therapy is often required with statins or fibrates. The choice of hypolipidaemic drugs should take into account potential pharmacological interactions with antiretroviral agents. PMID:14645323

    Human immunodeficiency virus (HIV) infection includes acute, early, chronic, and late stages. Acute HIV infection lasts approximately 3 weeks and early HIV infection, which includes acute HIV infection, lasts approximately 7 weeks. Many testing and blood screening algorithms detect HIV antibodies about 3 weeks after HIV infection. Incidence estimates are based on results of modeling, cohort studies, surveillance, and/or assays. Viral load is the key modifiable risk factor for HIV transmission and peaks during acute and early HIV infection. Empirical evidence characterizing the impact of acute and early HIV infection on the spread of the HIV epidemic are limited. Time trends of HIV prevalence collected from concentrated and generalized epidemics suggest that acute and early HIV infection may have a limited role in population HIV transmission. Collectively, these data suggest that acute and early HIV infection is relatively short and does not currently require fundamentally different programmatic approaches to manage the HIV/AIDS epidemic in most settings. Research and surveillance will inform which epidemic contexts and phases may require tailored strategies for these stages of HIV infection. PMID:26310309

    We report the case of a 47-year-old female patient with rheumatoid arthritis and HIV infection presenting with a 3-week history of a painful swollen knee, increased serum inflammatory markers, and a low CD4 lymphocyte count. The diagnosis of TB arthritis was made by synovial fluid culture, GeneXpert/PCR, and confirmed by histopathology of a synovial biopsy. A mini literature review suggests that although HIV infection is associated with extrapulmonary TB, osteoarticular TB is a relatively unusual presentation in an HIV positive patient. The diagnostic utility of the GeneXpert test is explored. We also describe the patient's good response to an intra-articular corticosteroid injection in combination with standard anti-TB therapy.

  17. Modeling the three stages in HIV infection.

    A typical HIV infection response consists of three stages: an initial acute infection, a long asymptomatic period and a final increase in viral load with simultaneous collapse in healthy CD4+T cell counts. The majority of existing mathematical models give a good representation of either the first two stages or the last stage of the infection. Using macrophages as a long-term active reservoir, a deterministic model is proposed to explain the three stages of the infection including the progression to AIDS. Simulation results illustrate how chronic infected macrophages can explain the progression to AIDS provoking viral explosion. Further simulation studies suggest that the proposed model retains its key properties even under moderately large parameter variations. This model provides important insights on how macrophages might play a crucial role in the long term behavior of HIV infection. PMID:23238280

    Cryptococcus neoformans is an encapsulated fungal pathogen that is remarkable for its tendency to cause meningoencephalitis, especially in patients with AIDS. While disease is less common in children than adults, it remains an important cause of morbidity and mortality among HIV-infected children without access to anti-retroviral therapy. This review highlights recent insights into both the biology and treatment of cryptococcosis with a special emphasis on the pediatric literature. PMID:27443557

    2016-04-01

    Analysis of the prevalence and incidence of HIV infection globally reveal striking variances with regard to continent, country, region and gender. Of the global total of 33 million people infected with HIV, approximately 65% are in sub-Saharan African countries and 15% in South and South-East Asia with the remaining 20% spread over the rest of the world. As a percentage of the population, the Caribbean at 1.1% is second only to sub-Saharan Africa (5.5%). The majority of the world's HIV is in women. Deaths from HIV are twenty-fold greater in Africa than in Europe or the USA. Individual countries in sub-Saharan Africa show huge variances in the HIV+ prevalence with most West African countries having a rate of less than 2% whilst southern African countries including Swaziland and Botswana have rates of around 25%. Environment, education and social habits all contribute to the HIV infection rates. Similar variations between countries are seen in SE Asia with Cambodia and Papua New Guinea having rates three times greater than Pakistan. One of the most striking examples of inequality is in life years added to HIV populations as a result of antiretroviral therapy. UN AIDS figures over 1996-2008 suggest an average of 2.88 added years in the USA and Europe, but only 0.1 in sub-Saharan Africa, a thirty-fold difference largely due to accessibility to ART. ART leads to a reduction in oral lesions but it is estimated that some 10 million HIV+ subjects do not have access to oral care. Thus, inequalities exist both for HIV infection and for the associated oral lesions, mainly related to ART access. HIV infection and oral mucosal lesions both appear to be related to general social determinants of health. Oral HCW must be part of mainstream healthcare teams to address these inequalities.

    Fosamprenavir is a protease inhibitor (PI) approved for the treatment of HIV-1 infection. Fosamprenavir is a prodrug of amprenavir developed to reduce the pill burden yet maintain the unique resistance pattern and efficacy associated with amprenavir. In a head-to-head, noninferiority trial in antiretroviral treatment-naive HIV-infected patients, the antiviral efficacy and tolerability of ritonavir-boosted fosamprenavir was not inferior to ritonavir-boosted lopinavir, when the PIs were combined with two other nucleoside reverse transcriptase inhibitors. There are fewer studies published about fosamprenavir use in antiretroviral treatment-experienced HIV-infected patients. The high genetic barrier to the development of resistance to fosamprenavir and the low level of cross-resistance between ritonavir-boosted fosamprenavir and other PI regimens are notable. As with amprenavir, gastrointestinal disturbance and rash are the most frequent short-term treatment-limiting events with fosamprenavir. Treatment with ritonavir-boosted fosamprenavir can produce a durable response. To date, fosamprenavir is one of the recommended preferred PI components for the treatment of antiretroviral-naive HIV-infected patients. PMID:17547501

    BACKGROUND. To learn more about how people who did not volunteer for testing react to information about HIV infection, we assessed short-term behavior changes in HIV-positive blood donors. METHODS. Blood donors who were notified at the New York Blood Center that they were HIV positive were asked to participate in a study. A nurse elicited a medical history, performed a limited medical examination, and asked participants to complete a questionnaire that included questions about drug use, sexual behavior, and psychological characteristics. Participants were asked to return in 2 weeks to complete another questionnaire. RESULTS. Many fewer men and women reported engaging in unsafe sexual behaviors in the 2 weeks preceding the follow-up visit than had reported such behaviors prior to notification. These changes were greater than those other investigators have reported, but about 40% of the participants still reported unsafe sexual activity at the follow-up interview. CONCLUSIONS. To make nonvolunteer screening programs for HIV infection more effective in reducing the spread of HIV infection, we need to learn more about how to help people change their high-risk behaviors.

    Psychoanalytic writers have traced the etiology of borderline personality disorder (BPD) to be a preoedipal disturbance in the mother-child relationship. Despite the prevalence of theories focusing on the role of mothering in the development of BPD, few empirical studies have tested the hypothesis that borderlines were the recipients of unempathic mothering. The current preliminary study compared 13 mothers of borderline adolescents with 13 mothers of normal adolescents. This study found that mothers of borderlines tended to conceive of their children egocentrically, as need-gratifying objects, rather than as individuals with distinct and evolving personalities. This study also found that the mothers of borderlines reported raising their daughters in extremely chaotic families struggling to cope with multiple hardships, including divorce and financial worries. The stressful environmental circumstances reported by the mothers likely affected the borderline daughters directly as well as the mothers' ability to parent effectively and empathically. The results of this study suggest that, as predicted by psychoanalytic theory, a problematic mother-child relationship may play a significant role in the genesis of borderline pathology; however, the life circumstances that contextualize the mother-child relationship also need to be considered when accounting for the etiology of BPD.

    Sclerostin is linked to bone physiology and cardiovascular disease through the Wnt/β-catenin signaling pathway. The goal of this study was to determine if sclerostin is related to bone physiology and cardiovascular disease during antiretroviral treatment in HIV-infected persons. This was a cross-sectional analysis from study entry into the Stopping Atherosclerosis and Treating Unhealthy bone with RosuvastatiN in HIV (SATURN) trial, an ongoing randomized trial comparing rosuvastatin to placebo in HIV-infected adults on antiretroviral therapy. Plasma sclerostin was measured at study entry by ELISA from participants with available samples. Spearman correlation and multivariable linear regression were used to test relationships between sclerostin and bone density or bone turnover and cardiovascular disease. Among 139 HIV-infected participants (median age 46 years, CD4 lymphocyte count 614 cells/μl), the median plasma sclerostin level was 444.1 (IQR 330.3, 570.1) pg/ml. Correlations were detected between sclerostin and age (r=0.26), lumbar spine Z-score (r=0.31), RANKL (r=-0.21), carotid intima-media thickness (CIMT, r=0.19), and sVCAM-1 (r=0.27), p<0.05. No significant correlations were detected between sclerostin and current (r=0.006) or nadir CD4 count (r=0.11). While associations between sclerostin, lumbar spine Z-score, and sVCAM-1 were robust to covariate adjustment (p<0.01), association with CIMT was no longer significant (p=0.08). Our findings provide preliminary support for a relationship between sclerostin and bone mineral density in HIV-infected persons. The Wnt/β-catenin pathway should be investigated as a potential mechanism for loss of bone mineral density in treated HIV infection. PMID:25919636

    The frequency of neurodegenerative markers among long surviving HIV infected individuals is unknown, therefore, the present study investigated the frequency of α-synuclein, β-amyloid and HIV-associated brain pathology in the brains of older HIV infected individuals. We examined the substantia nigra of 73 clinically well-characterized HIV infected individuals aged 50 to 76 years from the National NeuroAIDS Tissue Consortium. We also examined the frontal and temporal cortical regions of a subset of 36 individuals. The brain regions were examined for the presence of α-synuclein, β-amyloid and HIV-associated brain pathology. Neuritic α-synuclein expression was found in 16% (12/73) of the substantia nigra of the HIV+ cases and none of the older control cases (0/18). β-amyloid deposits were prevalent and found in nearly all of the HIV+ cases (35/36). Despite these increases of degenerative pathology, HIV-associated brain pathology was present in only 10% of cases. Among older HIV+ adults HIV-associated brain pathology does not appear elevated; however, the frequency of both α-synuclein and β-amyloid is higher than that found in older healthy persons. The increased prevalence of α-synuclein and β-amyloid in the brains of older HIV-infected individuals may predict an increased risk of developing neurodegenerative disease. PMID:19115126

    Tobacco use is inextricably linked to a number of health risks both in the general and HIV-infected populations. There is, however, a dearth of research on effective tobacco control programs among people living with HIV, and especially among adolescents, young adults and pregnant women, groups with heightened or increased vulnerability secondary to tobacco use. Adolescents and young adults constitute a growing population of persons living with HIV infection. Early and continued tobacco use in this population living with a disease characterized by premature onset multimorbidity and chronic inflammation is of concern. Additionally, there is an increased acuity for tobacco control among HIV-infected pregnant women to reduce pregnancy morbidity and improve fetal outcome. This review will provide an important summary of current knowledge of tobacco use among HIV-infected adolescents, young adults and pregnant women. The effects of tobacco use in these specific populations will be presented and the current state of tobacco control within these populations, assessed. PMID:23778059

    Occupational settings offer an ideal opportunity to provide preventive health services for HIV-infected workers. A specialized clinic was established in a mining hospital in the Free State, South Africa, with the primary aim of delivering preventive therapy such as isoniazid to those at high risk of tuberculosis (individuals with HIV infection or silicosis), and cotrimoxazole to those at highest risk for opportunistic infections. The clinic design has taken regard of the importance of minimizing stigma, protecting confidentiality, monitoring potential side effects, supporting adherence and identification of prophylaxis failure. The clinic opened in April 1999 and, by August 2001, 1773 patients had attended at least once; 1762 are HIV-infected and 11 have silicosis. Of those with HIV infection, most were asymptomatic at their first visit. The clinic has achieved high acceptability: 99% of persons who were actively recruited to the service agreed to attend. The number still attending after a median of 13 months from recruitment was 1,270 (72%) and only 48 (2.7%) have declined continued attendance. Most losses were due to termination of employment unrelated to a medical condition. The clinic has already been successfully replicated in two other regions of the mining health service in South Africa and provides a model for workplace HIV clinical services that could be used for implementation of further interventions such as antiretroviral therapy.

    Improving outcomes for people with HIV and mental illness will be critical to meeting the goals of the US National HIV/AIDS Strategy. In a retrospective analysis of the 2008–2010 cycles of the locally representative Philadelphia Medical Monitoring Project, we compared the proportions of HIV-infected adults with and without mental illness: (1) retained in care (≥2 primary HIV visits separated by ≥90 days in a 12-month period); (2) prescribed antiretroviral therapy (ART) at any point in a 12-month period; and (3) virally suppressed (HIV-1 RNA ≤200 copies/mL at the last measure in the 12-month period). Multivariable regression assessed associations between mental illness and the outcomes, adjusting for age, gender, race/ethnicity, insurance, alcohol abuse, injection drug use, CD4 count, and calendar year. Of 730 HIV-infected persons, representative of 9409 persons in care for HIV in Philadelphia, 49.0 % had mental illness. In adjusted analyses, there were no significant differences in retention (91.3 vs. 90.3 %; AOR 1.30, 95 % CI 0.63–2.56) and prescription of ART (83.2 vs. 88.7 %; AOR 0.79, 95 % CI 0.49–1.25) between those with and without mental illness. However, mentally ill patients were less likely to achieve viral suppression than those without mental illness (65.9 vs. 74.4 %; AOR 0.64, 95 % CI 0.46–0.90). These findings argue for the need to optimize ART adherence in this population. PMID:25931243

    We have observed significantly increased HIV infection in HIV infected macrophages in the presence of cocaine that could be due to the downregulation of BST2 restriction factor in these cells. In human inflammasome PCR array, among different involved in inflammasome formation, in HIV infected macrophages in the presence of cocaine, we have observed significant upregulation of NLRP3, AIM2 genes and downstream genes IL-1β and PTGS2. Whereas negative regulatory gene MEFV was upregulated, CD40LG and PYDC1 were significantly downregulated. Among various NOD like receptors, NOD2 was significantly upregulated in both HIV alone and HIV plus cocaine treated cells. In the downstream genes, chemokine (C-C motif) ligand 2 (CCL2), CCL7 and IL-6 were significantly up regulated in HIV plus cocaine treated macrophages. We have also observed significant ROS production (in HIV and/or cocaine treated cells) which is one of the indirect-activators of inflammasomes formation. Further, we have observed early apoptosis in HIV alone and HIV plus cocaine treated macrophages which may be resultant of inflammasome formation and cspase-1 activation. These results indicate that in case of HIV infected macrophages exposed to cocaine, increased ROS production and IL-1β transcription serve as an activators for the formation of NLRP3 and AIM2 mediated inflammasomes that leads to caspase 1 mediated apoptosis.

    assessments are recommended before treatment, and monitoring during treatment is recommended to assess response, adverse effects, and adherence. Approaches are recommended to improve linkage to and retention in care are provided. Daily tenofovir disoproxil fumarate/emtricitabine is recommended for use as preexposure prophylaxis to prevent HIV infection in persons at high risk. When indicated, postexposure prophylaxis should be started as soon as possible after exposure. CONCLUSIONS AND RELEVANCE Antiretroviral agents remain the cornerstone of HIV treatment and prevention. All HIV-infected individuals with detectable plasma virus should receive treatment with recommended initial regimens consisting of an InSTI plus 2 NRTIs. Preexposure prophylaxis should be considered as part of an HIV prevention strategy for at-risk individuals. When used effectively, currently available ARVs can sustain HIV suppression and can prevent new HIV infection. With these treatment regimens, survival rates among HIV-infected adults who are retained in care can approach those of uninfected adults. PMID:27404187

    The sexually transmitted disease (STD), chancroid, is the greatest factor for HIV infections in Africa like syphilis is in the US. 3 physicians suggest that reducing the incidence of STDs may reduce the spread of HIV. Risk factors for HIV include current or history of STD in women and bisexual men, pelvic inflammatory disease, semen, copper releasing IUDs, contraceptive dermatitis, malnutrition/food allergy, environmental pollutants, genetic make up, and prostitutes. HIV infected persons should use condoms to not only protect partners but to prevent repeated contact with HIV which influences the clinical outcome. Condom use for contraception is not widely practiced in some areas, however, including Central Africa and Haiti. Condom use has increased in the US because IUDs have been removed from the market, fear of HIV infection, and discontinued use of oral contraceptives in older women. Urticarial reactions secondary to a copper IUD often occur in adolescent women, but clears when the IUD is removed. Traces of nickel in the copper wire used in IUDs often induce an allergic reaction. Allergic reactions are cofactors of HIV which can be made worse if coupled with excessive menstrual bleeding and HIV infected semen cells entering the uterus via the IUD tail. Many countries have integrated family planning services with other public health services, such as STD clinics that address AIDS. Integrated services should provide STD services and contraception and involve males and be accessible to them. Comprehensive school based clinical model should be implemented into schools and colleges. Counselors should advice HIV infected women not to have any more children. These women should get top priority to family planning services. HIV antibody testing for women should be done at any center where women may be including family planning centers and prisons.

    We present the rationale and design of a randomized, double-blind, placebo-controlled trial of vitamin supplements among HIV-positive pregnant women in Dar es Salaam, Tanzania. Higher levels of intake of vitamins A, B, C, and E may decrease the risk of vertical transmission and progression of HIV infection by enhancing maternal and infant immune function; by reducing viral load in the blood, breast milk, or lower genital tract secretions; and/or by strengthening the placental barrier to infection. Eligible pregnant women were randomized to receive vitamin A, multivitamins excluding A, vitamin A and multivitamins, or placebo. The main endpoints include vertical transmission of HIV infection, as assessed by examination of infection in infants using polymerase chain reaction (PCR), and progression of HIV disease as measured by the WHO clinical staging system. Over a period of 2 years, 13,876 women were tested for HIV infection, with appropriate pre- and posttest counseling, to enroll 1085 consenting HIV-positive women. The trial assesses women and their children once a month for a minimum of 18 months after delivery or up to the end of this 5-year study. We examine recruitment strategies and means of enhancing cohort retention in long-term follow-up. We assess compliance with the use of supplements by direct questioning, by counting pills, and biochemically by using serum beta-carotene and urine riboflavin levels. Briefly, we discuss ethical issues related to the conduct of AIDS prevention trials in this setting. In sub-Saharan Africa, most HIV-infected persons lack access to the relevant antiretroviral and prophylactic drugs, and the region urgently needs low-cost treatments and preventive strategies. The Tanzania trial should provide valuable data to address the effect of vitamin supplements in the transmission and progression of HIV infection. PMID:10027501

  18. Revised surveillance case definition for HIV infection--United States, 2014.

    2014-04-11

    Following extensive consultation and peer review, CDC and the Council of State and Territorial Epidemiologists have revised and combined the surveillance case definitions for human immunodeficiency virus (HIV) infection into a single case definition for persons of all ages (i.e., adults and adolescents aged ≥13 years and children aged <13 years). The revisions were made to address multiple issues, the most important of which was the need to adapt to recent changes in diagnostic criteria. Laboratory criteria for defining a confirmed case now accommodate new multitest algorithms, including criteria for differentiating between HIV-1 and HIV-2 infection and for recognizing early HIV infection. A confirmed case can be classified in one of five HIV infection stages (0, 1, 2, 3, or unknown); early infection, recognized by a negative HIV test within 6 months of HIV diagnosis, is classified as stage 0, and acquired immunodeficiency syndrome (AIDS) is classified as stage 3. Criteria for stage 3 have been simplified by eliminating the need to differentiate between definitive and presumptive diagnoses of opportunistic illnesses. Clinical (nonlaboratory) criteria for defining a case for surveillance purposes have been made more practical by eliminating the requirement for information about laboratory tests. The surveillance case definition is intended primarily for monitoring the HIV infection burden and planning for prevention and care on a population level, not as a basis for clinical decisions for individual patients. CDC and the Council of State and Territorial Epidemiologists recommend that all states and territories conduct case surveillance of HIV infection using this revised surveillance case definition.

    Several renal complications may occur during HIV infection, especially in advanced stages related to HIV, to other infectious agents and/or drugs. Little is known about the prevalence of renal diseases that may occur as a complication of or related to HIV infection in asymptomatic patients. This is a single center cross-sectional study of asymptomatic HIV(+) patients referred to a nefrology care service at an Argentine hospital to look for the presence of renal abnormalities. Fifty two consecutive patients were studied between April and November 2008. Patients underwent plasma and urine analysis, ultrasound, and kidney biopsy as needed. Mean age was 39.9 +/- 10.6 years, 88% were male, time from HIV diagnosis 53.2 +/- 41.2 months (2-127); 71% had HIV-disease and 77% were on antiretroviral therapy. Mean plasma HIV-RNA copies number was 7.043 +/- 3.322 and CD4+ cell count: 484 +/- 39. Pathologic findings in urine analysis were present in 30.7% of patients: albuminuria 16.6%, microscopic hematuria 11.5%, hypercalciuria 10.8% and crystalluria 6%. Mean glomerular filtration rate was 102.2 +/- 22.95 ml/min (34-149) and 41% of patients could be classified in stages 1 to 3 of chronic kidney disease. Renal abnormalities prevaled in older patients without relationship with presence of HIV-disease. Two patients were biopsied and the findings included: tubulointerstitial nephritis with presence of crystal deposition in one and IgA nephropathy in the other. No HIV-associated nephropathy was detected. The broad spectrum and the high prevalence of lesions found in this series suggest that asymptomatic HIV-infected patients should routinely undergo renal evaluation. PMID:20529774

  20. The stochastic dance of early HIV infection

    2005-12-01

    The stochastic nature of early HIV infection is described in a series of models, each of which captures aspects of the dance of HIV during the early stages of infection. It is to this highly variable target that the immune response must respond. The adaptability of the various components of the immune response is an important aspect of the system's operation, as the nature of the pathogens that the response will be required to respond to and the order in which those responses must be made cannot be known beforehand. As HIV infection has direct influence over cells responsible for the immune response, the dance predicts that the immune response will be also in a variable state of readiness and capability for this task of adaptation. The description of the stochastic dance of HIV here will use the tools of stochastic models, and for the most part, simulation. The justification for this approach is that the early stages and the development of HIV diversity require that the model to be able to describe both individual sample path and patient-to-patient variability. In addition, as early viral dynamics are best described using branching processes, the explosive growth of these models both predicts high variability and rapid response of HIV to changes in system parameters.In this paper, a basic viral growth model based on a time dependent continuous-time branching process is used to describe the growth of HIV infected cells in the macrophage and lymphocyte populations. Immigration from the reservoir population is added to the basic model to describe the incubation time distribution. This distribution is deduced directly from the modeling assumptions and the model of viral growth. A system of two branching processes, one in the infected macrophage population and one in the infected lymphocyte population is used to provide a description of the relationship between the development of HIV diversity as it relates to tropism (host cell preference).

    Because of the limited tropism of HIV, in vivo modeling of this virus has been almost exclusively limited to other lentiviruses such as SIV that reproduce many important characteristics of HIV infection. However, there are significant genetic and biological differences among lentiviruses and some HIV-specific interventions are not effective against other lentiviruses in non-human hosts. For these reasons much emphasis has recently been placed on developing alternative animal models that support HIV replication and recapitulate key aspects of HIV infection and pathogenesis in humans. Humanized mice, CD34+ hematopoietic progenitor cell transplanted immunodeficient mice and in particular mice also implanted with human thymic/liver tissue (BLT mice) that develop a functional human immune system, have been the focus of a great deal of attention as possible models to study virtually all aspects of HIV biology and pathogenesis. Humanized mice are systemically reconstituted with human lymphoid cells offering rapid, reliable and reproducible experimental systems for HIV research. Peripheral blood of humanized mice can be readily sampled longitudinally to assess reconstitution with human cells and to monitor HIV replication permitting the evaluation of multiple parameters of HIV infection such as viral load levels, CD4+ T cell depletion, immune activation, as well as the effects of therapeutic interventions. Of high relevance to HIV transmission is the extensive characterization and validation of the reconstitution with human lymphoid cells of the female reproductive tract and of the gastrointestinal tract of humanized BLT mice that renders them susceptible to both vaginal and rectal HIV infection. Other important attributes of all types of humanized mice include: 1) their small size and cost that make them broadly accessible; 2) multiple cohorts of humanized mice can be made from multiple human donors and each cohort has identical human cells, permitting control of

    Cytokines are major controller of HIV replication and represent, at the same time, a target for viral-induced immune dysregulation. This mutual relationship has profound implications for both active HIV replication and immune-mediated governance of latency; in addition, cytokines have therapeutic value in the perspective of immune reconstitution. In the current article we will review the most relevant aspects emerged in almost 20 years of research in this area with particular reference to the distinct, but interconnected contribution of the most simple (cell lines) to the most complex (animal) models of HIV infection.

    Previous studies in HIV patients have reported autoantibodies to several human proteins, including erythropoietin (EPO), interferon-α (IFN-α), interleukin-2 (IL-2), and HLA-DR, as potential mediators of anemia or immunosuppression. The etiology of these autoantibodies has been attributed to molecular mimicry between HIV epitopes and self-proteins. Here, the Luciferase Immunoprecipitation System (LIPS) was used to investigate the presence of such autoantibodies in HIV-infected adults. High levels of antibodies to HIV proteins such as capsid (p24), matrix (p17), envelope (gp41), and reverse transcriptase (RT) were detected using LIPS in both untreated and anti-retroviral-treated HIV-infected individuals but not in uninfected controls. LIPS readily detected anti-EPO autoantibodies in serum samples from subjects with presumptive pure red cell aplasia but not in any of the samples from HIV-infected or uninfected individuals. Similarly, subjects with HIV lacked autoantibodies to IFN-α, IL-2, HLA-DR and the immunoglobulin lambda light chain; all purported targets of molecular mimicry. While molecular mimicry between pathogen proteins and self-proteins is a commonly proposed mechanism for autoantibody production, the findings presented here indicate such a process is not common in HIV disease.

    Introduction Streptococcus pneumoniae is the commonest cause of bacteremic pneumonia among HIV-infected persons. As more countries with high HIV prevalence are implementing infant pneumococcal conjugate vaccine (PCV) programs, we aimed to describe the baseline clinical characteristics of adult invasive pneumococcal disease (IPD) in the pre-PCV era in South Africa in order to interpret potential indirect effects following vaccine use. Methods National, active, laboratory-based surveillance for IPD was conducted in South Africa from 1 January 2003 through 31 December 2008. At 25 enhanced surveillance (ES) hospital sites, clinical data, including HIV serostatus, were collected from IPD patients ≥ 5 years of age. We compared the clinical characteristics of individuals with IPD in those HIV-infected and -uninfected using multivariable analysis. PCV was introduced into the routine South African Expanded Program on Immunization (EPI) in 2009. Results In South Africa, from 2003–2008, 17 604 cases of IPD occurred amongst persons ≥ 5 years of age, with an average incidence of 7 cases per 100 000 person-years. Against a national HIV-prevalence of 18%, 89% (4190/4734) of IPD patients from ES sites were HIV-infected. IPD incidence in HIV-infected individuals is 43 times higher than in HIV-uninfected persons (52 per 100 000 vs. 1.2 per 100 000), with a peak in the HIV-infected elderly population of 237 per 100 000 persons. Most HIV-infected individuals presented with bacteremia (74%, 3 091/4 190). HIV-uninfected individuals were older; and had more chronic conditions (excluding HIV) than HIV-infected persons (39% (210/544) vs. 19% (790/4190), p<0.001). During the pre-PCV immunization era in South Africa, 71% of serotypes amongst HIV-infected persons were covered by PCV13 vs. 73% amongst HIV-uninfected persons, p = 0.4, OR 0.9 (CI 0.7–1.1). Conclusion Seventy to eighty-five percent of adult IPD in the pre-PCV era were vaccine serotypes and 93% of cases had recognized risk

    The Centers for Disease Control and Prevention (CDC) Sexually Transmitted Disease (STD) Treatment Guidelines were last updated in 2006. To update the “Clinical Guide to Prevention Services” section of the 2010 CDC STD Treatment Guidelines, we reviewed the recent science with reference to interventions designed to prevent acquisition of STDs, including human immunodeficiency virus (HIV) infection. Major interval developments include (1) licensure and uptake of immunization against genital human papillomavirus, (2) validation of male circumcision as a potent prevention tool against acquisition of HIV and some other sexually transmitted infections (STIs), (3) failure of a promising HIV vaccine candidate to afford protection against HIV acquisition, (4) encouragement about the use of antiretroviral agents as preexposure prophylaxis to reduce risk of HIV and herpes simplex virus acquisition, (5) enhanced emphasis on expedited partner management and rescreening for persons infected with Chlamydia trachomatis and Neisseria gonorrhoeae, (6) recognition that behavioral interventions will be needed to address a new trend of sexually transmitted hepatitis C among men who have sex with men, and (7) the availability of a modified female condom. A range of preventive interventions is needed to reduce the risks of acquiring STI, including HIV infection, among sexually active people, and a flexible approach targeted to specific populations should integrate combinations of biomedical, behavioral, and structural interventions. These would ideally involve an array of prevention contexts, including (1) communications and practices among sexual partners, (2) transactions between individual clients and their healthcare providers, and (3) comprehensive population-level strategies for prioritizing prevention research, ensuring accurate outcome assessment, and formulating health policy.

    Approximately 80% of new HIV infections in the United States occur in men. Four out of five men diagnosed with HIV infection are men who have sex with men (MSM), with an increasing proportion of young MSM (i.e. ≤24 years of age). We performed a retrospective analysis 11,873 cisgender men participating in a community based HIV screening program in San Diego between 2008 and 2014 to characterize the HIV prevalence and sexual risk behaviors among young men. In young heterosexual men HIV prevalence was lower compared to heterosexual men between 25 and 49 years of age (0.3% vs. 1.4%, p = 0.043). Among young MSM, HIV prevalence was 5.5%, per test positivity rate 3.6%, and HIV incidence 3.4 per 100 person years (95% CI 2.2-5.4). Per test positivity rate (p = 0.008) and incidence (p < 0.001) were significantly higher among young MSM than among MSM above 24-years of age. Young MSM diagnosed with HIV infection reported significantly more serodiscordant condomless anal intercourse, bacterial sexually transmitted infections, and higher rates of methamphetamine and gamma hydroxybutyrate use when compared to young MSM who tested negative. In conclusion, young MSM are particularly vulnerable to HIV infection and may represent ideal candidates for targeted prevention interventions that increase testing uptake and/or decrease the risk of acquiring HIV infection.

    Introduction: Since 2004, the authors have been operating First Call NYU, an outreach program to identify acute and recent HIV infections, also called primary HIV infections, among targeted at-risk communities in the New York City (NYC) metropolitan area. Materials and Methodology: First Call NYU employed mass media advertising campaigns, outreach to healthcare providers in NYC, and Internet-based efforts including search engine optimization (SEO) and Internet-based advertising to achieve these goals. Results: Between October 2004 and October 2008, 571 individuals were screened through this program, leading to 446 unique, in-person screening visits. 47 primary HIV infections, including 14 acute and 33 recent HIV infections, were identified. Discussion: Internet and traditional recruitment methods can be used to increase self-referrals for screening following possible exposure to HIV. Conclusion: Community education of at-risk groups, with the goal of increased self-diagnosis of possible acute HIV infection, may be a useful addition to traditional efforts to identify such individuals.

    Recent developments in molecular techniques have allowed researchers to identify previously uncultured organisms, which has propelled a vast expansion of our knowledge regarding our commensal microbiota. Interest in the microbiome specific to HIV grew from earlier findings suggesting that bacterial translocation from the intestines is the cause of persistent immune activation despite effective viral suppression with antiretroviral therapy (ART). Studies of SIV infected primates have demonstrated that Proteobacteria preferentially translocate and that mucosal immunity can be restored with probiotics. Pathogenic SIV infection results in a massive expansion of the virome, whereas non-pathogenic SIV infection does not. Human HIV infected cohorts have been shown to have microbiota distinctive from that of HIV negative controls and efforts to restore the intestinal microbiome via probiotics have often had positive results on host markers. The microbiota of the genital tract may play a significant role in acquisition and transmission of HIV. Modification of commensal microbial communities likely represents an important therapeutic adjunct to treatment of HIV. Here we review the literature regarding human microbiome in HIV infection.

    The Health Belief Model (HBM) has been widely used as a framework to explain health behaviors in diverse populations, but little HBM research has focused on HIV-infected women and their increased risks for cervical cancer. We used Champion's Health Belief Model and Self-Efficacy scales to assess relationships between Pap test adherence and constructs of the HBM among 300 HIV-infected women. In addition, we assessed the relationship between HPV and cervical cancer knowledge and key HBM concepts. Participants reported low levels of knowledge regarding risk for cervical cancer and HPV. They perceived lower personal risk for cervical cancer. Women with higher perceived self-efficacy and lower perceived barrier scores reported better Pap test adherence. Findings indicate that HIV-infected women are not aware of the risk for cervical cancer and may not take preventive actions. Further research is needed to identify the full range of factors that impact adherence to cervical cancer screening. PMID:25769754

    Rationale: HIV-infected persons on antiretroviral therapy (ART) remain at higher risk of pulmonary tuberculosis (TB) than HIV-uninfected individuals. This increased susceptibility may be caused by impairment of alveolar macrophage (AM) function and/or mycobacteria-specific alveolar CD4+ T-cell responses observed in HIV-infected ART-naive adults. Objectives: To determine whether ART was associated with improvement in both AM function, assessed by phagosomal proteolysis, and alveolar CD4+ T-cell responses to Mycobacterium in HIV-infected individuals. Methods: Peripheral blood was drawn and bronchoalveolar lavage (BAL) performed on healthy, 35 HIV-uninfected, 25 HIV-infected ART-naive, and 50 HIV-infected ART-treated asymptomatic adults. Phagosomal proteolysis of AM was assessed with fluorogenic beads. Mycobacteria-specific CD4+ T-cell responses were measured by intracellular cytokine staining. Measurements and Main Results: HIV-infected adults on ART exhibited lower plasma HIV viral load and higher blood CD4+ T-cell count than ART-naive adults. AM proteolysis and total mycobacteria-specific Th1 CD4+ T-cell responses in individuals on ART for greater than or equal to 4 years were similar to HIV-uninfected control subjects but those on ART for less than 4 years had impaired responses. Total influenza-specific alveolar Th1 CD4+ T-cell responses were intact in all individuals receiving ART. In contrast, BAL and blood mycobacteria-specific polyfunctional CD4+ T-cell responses were impaired in adults on ART irrespective of duration. Conclusions: AM and mycobacteria-specific alveolar CD4+ T-cell responses in HIV-infected adults on ART for less than 4 years are impaired and may partly explain the high risk of TB in HIV-infected individuals on ART. Strategies to augment ART to improve lung immune cell function and reduce the high incidence of TB in HIV-infected adults who initiate ART should be investigated. PMID:25225948

    Our objective was to compare obesity prevalence among human immunodeficiency virus (HIV)-infected adults receiving care and the U.S. general population and identify obesity correlates among HIV-infected men and women.Cross-sectional data was collected in 2009 to 2010 from 2 nationally representative surveys: Medical Monitoring Project (MMP) and National Health and Nutrition Examination Survey (NHANES).Weighted prevalence estimates of obesity, defined as body mass index ≥30.0 kg/m, were compared using prevalence ratios (PR, 95% confidence interval [CI]). Correlates of obesity in HIV-infected adults were examined using multivariable logistic regression.Demographic characteristics of the 4006 HIV-infected adults in MMP differed from the 5657 adults from the general U.S. population in NHANES, including more men (73.2% in MMP versus 49.4% in NHANES, respectively), black or African Americans (41.5% versus 11.6%), persons with annual incomes <$20,000 (64.5% versus 21.9%), and homosexuals or bisexuals (50.9% versus 3.9%). HIV-infected men were less likely to be obese (PR 0.5, CI 0.5-0.6) and HIV-infected women were more likely to be obese (PR1.2, CI 1.1-1.3) compared with men and women in the general population, respectively. Among HIV-infected women, younger age was associated with obesity (<40 versus >60 years). Among HIV-infected men, correlates of obesity included black or African American race/ethnicity, annual income >$20,000 and <$50,000, heterosexual orientation, and geometric mean CD4+ T-lymphocyte cell count >200 cells/μL.Obesity is common, affecting 2 in 5 HIV-infected women and 1 in 5 HIV-infected men. Correlates of obesity differ for HIV-infected men and women; therefore, different strategies may be needed for the prevention and treatment. PMID:26166086

    Human immunodeficiency virus (HIV) is a fast replicating ribonucleic acid virus, which can easily mutate in order to escape the effects of drug administration. Hence, understanding the basic mechanisms underlying HIV persistence in the body is essential in the development of new therapies that could eradicate HIV infection. Lymphoid tissues are the primary sites of HIV infection. Despite the recent progress in real-time monitoring technology, HIV infection dynamics in a whole body is unknown. Mathematical modeling and simulations provide speculations on global behavior of HIV infection in the lymphatic system. We propose a new mathematical model that describes the spread of HIV infection throughout the lymphoid tissue network. In order to represent the volume difference between lymphoid tissues, we propose the proportionality of several kinetic parameters to the lymphoid tissues' volume distribution. Under this assumption, we perform extensive numerical computations in order to simulate the spread of HIV infection in the lymphoid tissue network. Numerical computations simulate single drug treatments of an HIV infection. One of the important biological speculations derived from this study is a drug saturation effect generated by lymphoid network connection. This implies that a portion of reservoir lymphoid tissues to which drug is not sufficiently delivered would inhibit HIV eradication despite of extensive drug injection. PMID:26507442

    Introduction Understanding factors affecting the time to recovery from acute mania is critical in the management of manic syndromes. The aim of this study was to determine the effect of HIV infection on time to recovery from acute mania. Methods We performed a retrospective study in which medical charts of individuals who were treated for acute mania were reviewed. Survival analysis with Cox regression models were used to compare time to recovery from an acute manic episode between human immunodeficiency virus (HIV)-positive individuals and HIV-negative individuals. Results Median survival time was one week for HIV-positive individuals and more than four weeks for HIV-negative individuals (χ2 = 18.4, P value = 0.000). HIV infection was the only marginally significant independent predictor of survival probability on the acute admission ward (hazards ratio 2.87, P = 0.06). Conclusion Acute mania in HIV-infected persons responds faster to psychotropic drugs compared with that in HIV-negative persons. PMID:22096397

Cerebrospinal fluid (CSF) from 69 HIV-infected Ugandan adults with meningitis was collected at diagnosis (n=51) and among persons with cryptococcal meningitis during therapeutic lumbar punctures (n=68). Cryopreserved CSF specimens were analyzed with BioFire FilmArray® Meningitis/Encephalitis panel, which targets 17 pathogens. The panel detected Cryptococcus in the CSF of patients diagnosed with a first episode of cryptococcal meningitis by fungal culture with 100% sensitivity and specificity and differentiated between fungal relapse and paradoxical immune reconstitution inflammatory syndrome in recurrent episodes. A negative FilmArray result was predictive of CSF sterility on follow-up lumbar punctures for cryptococcal meningitis. EBV was frequently detected in this immunosuppressed population (n=45). Other pathogens detected included: cytomegalovirus (n=2), varicella zoster virus (n=2), human herpes virus 6 (n=1), and Streptococcus pneumoniae (n=1). The FilmArray Meningitis/Encephalitis panel offers a promising platform for rapid meningitis diagnosis. PMID:26711635

    The prevention of the HIV infection remains relevant considering the dynamics of the epidemic and the slackening of the preventive behavior of certain populations. The strategies associate initiatives of universal prevention: information, education, communication, screening; and specific actions in the direction of the most exposed populations. The paradigms of prevention evolved a lot these last years to take into account the preventive efficiency of antiretrovirals. If the condom remains the reference method, it is advisable for the populations the most exposed today to associate all the tools of prevention: behavioral methods, screening and antiretroviral. The possibility given to non-governmental organizations to realize test of fast screening allowed to go to closer of the most exposed populations.The arrival on the market of the autotests must be supervised to touch the people who do not turn to the screening.

    A group of 89 prostitutes and 45 patients attending sexually transmitted disease clinics in Mogadishu, Somalia were examined for evidence of HIV infection. Both groups reported more than 1 sexual partner routinely and had sexual contacts with prostitutes. There was a significant amount of sexually transmitted diseases (STDs) in these two groups, with 11.2% and 6.7% respectively being culture positive for N. gonorrhoea. Among the prostitutes, 28.1% were positive for antibodies to T. pallidum while only 4.4% of the STD patients were positive. One isolate of N. gonorrhoea was resistant to penicillin. All study participants were negative for antibodies to HIV suggesting an extremely low prevalence of HIV in high risk behaviour groups in the capital city of Somalia. PMID:2226225

    HIV-infected children usually live in vulnerable situations, experiencing discrimination and stigma commonly felt by other people living with HIV/AIDS. The present study aims to analyse primary socialisation of HIV-infected children and adolescents recruited from a public health service in Rio de Janeiro (Brazil) as a social process that shapes a new generation of stigmatised and vulnerable persons. Research was informed by an interactionist perspective, focusing on key aspects of HIV-infected children and adolescents life histories under the conceptual frame of Erving Goffman's theories regarding "moral careers". Goffman defines the making of a moral career as the process through which a person learns that she/he possesses a particular attribute, which may lead her/him to be discredited by members of the surrounding society. We have identified aspects of life histories of HIV-vertically infected children and adolescents for each aspect of "moral career" as described by Goffman, relating them to as family structure, the experience of living HIV within the family, and the position and family role of a given subject. The patterns of "moral career" proposed by Goffman in 1963 were useful in identifying components of HIV-related stigma among children and adolescents. These include gender and social disadvantages, difficulty in coping with a child with a potentially severe disease, orphanhood, abandonment, adoption and disclosure of one's HIV serostatus. Primary socialisation of HIV-infected children and adolescents is a key piece of the complex HIV/AIDS-labelling process that could be targeted by interventions aiming to decrease stigma and marginalisation. Health care workers and stakeholders should be committed to ensuring education and guaranteeing the legal rights of this specific population, including the continuous provision of quality health care, full access to school and support to full disclosure of HIV diagnosis.

    In order to obtain a comprehensive form of mathematical models describing nonlinear phenomena such as HIV infection process and AIDS disease progression, it is efficient to introduce a general class of time-dependent evolution equations in such a way that the associated nonlinear operator is decomposed into the sum of a differential operator and a perturbation which is nonlinear in general and also satisfies no global continuity condition. An attempt is then made to combine the implicit approach (usually adapted for convective diffusion operators) and explicit approach (more suited to treat continuous-type operators representing various physiological interactions), resulting in a semi-implicit product formula. Decomposing the operators in this way and considering their individual properties, it is seen that approximation-solvability of the original model is verified under suitable conditions. Once appropriate terms are formulated to describe treatment by antiretroviral therapy, the time-dependence of the reaction terms appears, and such product formula is useful for generating approximate numerical solutions to the governing equations. With this knowledge, a continuous model for HIV disease progression is formulated and physiological interpretations are provided. The abstract theory is then applied to show existence of unique solutions to the continuous model describing the behavior of the HIV virus in the human body and its reaction to treatment by antiretroviral therapy. The product formula suggests appropriate discrete models describing the dynamics of host pathogen interactions with HIV1 and is applied to perform numerical simulations based on the model of the HIV infection process and disease progression. Finally, the results of our numerical simulations are visualized and it is observed that our results agree with medical and physiological aspects.

    The objective of this study was to investigate if early syphilis infection affects markers of HIV infection; CD4 T cells and viral load (VL). A retrospective study was performed on 160 HIV-positive patients (111 receiving antiretroviral therapy [ART] and 49 without ART). Early syphilis diagnosis was made in HIV patients during their follow-up at the HIV/AIDS Unit at a Greek Dermatology and Venereology Unit. The patients' blood tests were available at the time of diagnosis, as well as before and 12 weeks after early syphilis diagnosis. CD4 T cell counts and VL levels were measured. It was found that syphilis infection had a negative impact on the CD4 T cell counts in both groups, with reduced CD4 T cell counts observed in 84.6% (99/111) and 79.5% (39/49) of patients receiving and not receiving ART, respectively. After treatment for syphilis, CD4 T cell counts returned to pre-treatment levels in most patients, especially those receiving ART. There was a slight and transient VL increase. Patients receiving ART had a 27% increase in VL, compared to 71.4% among patients not receiving ART. Although the VL increase was slight (41-14,000 copies/ml) in the group under treatment, 4-5% (5/111) patients did not return to pre-treatment levels. Moreover, viral mutations associated with treatment resistance were identified in these patients. Early syphilis accelerates and complicates the progression of HIV infection. Early diagnosis and treatment of syphilis may prevent infection-associated complications in most instances. Consequently, prevention of syphilis and other sexually transmitted infections is of great importance for patients infected with HIV. PMID:26113517

    Acute encephalitis is a life-threatening condition. A wide variety of infectious agents are implicated and in many patients no cause is found. HIV acute seroconversion illness can rarely present as acute encephalitis. Although most experts agree in starting antiretroviral treatment in severe acute HIV infection, the evidence of the benefits are still lacking. The authors report a case of severe acute encephalitis as a primary presentation of HIV infection in which introduction of highly active antiretroviral treatment resulted in clinical recovery. This case highlights the need to consider HIV infection in the differential diagnosis of treatable viral encephalitis. PMID:22761210

    HIV-infected individuals are at an increased risk of cardiovascular disease (CVD) and other HIV-related co-morbidities. This is due in part to dyslipidemia associated with antiretroviral therapy and increased inflammation and immune activation from chronic HIV infection. Statins not only have potent lipid-lowering properties but are also anti-inflammatory and immunomodulators. Studies suggest that statin therapy in the HIV-infected population may decrease the risk of CVD and other non-AIDS-defining co-morbidities. This review summarizes the recent literature on statin use in the HIV setting. PMID:26126687

    Neutrophil to lymphocyte ratio (NLR) has been shown to predict occurrence of cardiovascular events in the general population. The aim of our study was to evaluate the role of NLR to predict major cardiovascular disease (CVD) events in HIV-infected subjects. We performed a retrospective cohort study of HIV-infected patients residing in the Local Health Authority (LHA) of Brescia, northern Italy, from 2000 to 2012. The incidence of CVD events in HIV-positive patients was compared with that expected in the general population living in the same area, computing standardized incidence ratios (SIRs). To evaluate the predictive role of NLR, univariate and multivariate Cox regression models were applied, computing hazard ratios (HRs). A total of 3766 HIV-infected patients (mean age 38.1 years, 71.3% males) were included (person-years 28768.6). A total of 134 CVD events occurred in 119 HIV-infected patients. A 2-fold increased risk (SIR 2.02) of CVD was found in HIV-infected patients compared to the general population. NLR levels measured at baseline and during follow-up were independently associated with CVD incidence, when also adjusting for both traditional CVD risk factors and HIV-related factors (HR 3.05 for NLR≥ 1.2). The area under the receiver operating characteristics (ROC) curve showed a modest, not statistically significant, increase, from 0.81 to 0.83, with addition of NLR to Framingham risk score model covariates. In conclusion an elevated NLR is a predictor of risk CVD in HIV-infected patients, independently from the traditional CVD risk factors. PMID:27148878

    Background. Heightened immune activation among human immunodeficiency virus (HIV)–infected persons may contribute to atherosclerosis. We assessed associations of serologic markers of monocyte activation, soluble CD163 (sCD163) and soluble CD14 (sCD14), and monocyte chemoattractant protein 1 (CCL2) with subclinical atherosclerosis among men with and those without HIV infection in the Multicenter AIDS Cohort Study. Methods. We performed noncontrast computed tomography on 906 men (566 HIV-infected men and 340 HIV-uninfected men), 709 of whom also underwent coronary computed tomographic angiography. Associations between each biomarker and the prevalence of coronary plaque, the prevalence of stenosis of ≥50%, and the extent of plaque were assessed by logistic and linear regression, adjusting for age, race, HIV serostatus, and cardiovascular risk factors. Results. Levels of all biomarkers were higher among HIV-infected men, of whom 81% had undetectable HIV RNA, and were associated with lower CD4+ T-cell counts. In the entire population and among HIV-infected men, higher biomarker levels were associated with a greater prevalence of coronary artery stenosis of ≥50%. Higher sCD163 levels were also associated with greater prevalences of coronary artery calcium, mixed plaque, and calcified plaque; higher CCL2 levels were associated with a greater extent of noncalcified plaque. Conclusions. sCD163, sCD14, and CCL2 levels were elevated in treated HIV-infected men and associated with atherosclerosis. Monocyte activation may increase the risk for cardiovascular disease in individuals with HIV infection. PMID:25362192

    Human immunodeficiency virus (HIV)-infected persons have higher rates of herpes zoster than HIV-uninfected individuals. We assessed whether twice daily treatment with 400 mg of oral acyclovir reduces the incidence of herpes zoster in a randomized, double-blind, placebo-controlled trial among 3408 persons coinfected with HIV and herpes simplex virus type 2. During 5175 person-years of follow-up, 26 cases of herpes zoster occurred among those assigned acyclovir, compared with 69 cases among those assigned placebo (rates, 1.00 and 2.68/100 person-years, respectively), a relative decrease of 62% (hazard ratio, 0.38; 95% confidence interval, .24-.67; P < .001). Daily acyclovir prophylaxis significantly reduced herpes zoster incidence among HIV-infected persons. PMID:26142452

    Context Abnormalities in the osteoprotegerin (OPG)/receptor activator of nuclear factor-κB ligand (RANKL) axis have been observed in HIV-infected persons and have been implicated in cardiovascular disease pathogenesis in the general population. Objective To determine associations of serum OPG and RANKL concentrations with HIV infection and subclinical atherosclerosis. Design Cross-sectional study nested within the Multicenter AIDS Cohort Study Setting Four US academic medical centers Participants There were 578 HIV-infected and 344 HIV-uninfected men. Main Outcome Measures Coronary artery calcium (CAC) was measured by non-contrast cardiac computed tomography (CT), and coronary stenosis and plaque characteristics (composition, presence and extent) were measured by coronary CT angiography. All statistical models were adjusted for traditional cardiovascular risk factors. Results OPG concentrations were higher and RANKL concentrations were lower among HIV-infected men compared to –uninfected men (p<0.0001 each). Among the HIV-infected men, higher OPG concentrations were associated with the presence of CAC, mixed plaque, and coronary stenosis > 50%, but not with plaque extent. In contrast, among HIV-uninfected men, higher OPG concentrations were associated with extent of both CAC and calcified plaque, but not their presence. RANKL concentrations were not associated with plaque presence or extent among HIV-infected men, but among HIV-uninfected men, lower RANKL concentrations were associated with greater extent of CAC and total plaque. Conclusions OPG and RANKL are dysregulated in HIV-infected men and their relationship to the presence and extent of subclinical atherosclerosis varies by HIV-status. The role of these biomarkers in CVD pathogenesis and risk prediction may be different in HIV-infected men. PMID:26090754

    The prevalence of human immunodeficiency virus (HIV) infection among people older than 50 years is increasing. Older HIV-infected patients are particularly at risk for polypharmacy because they often have multiple comorbidities that require pharmacotherapy. Overall, there is not much known with respect to both the impact of aging on medication use in HIV-infected individuals, and the potential for interactions with highly active antiretroviral therapy (HAART) and coadministered medications and its clinical consequences. In this review, we aim to provide an overview of polypharmacy with a focus on its impact on the HIV-infected older adult population and to also provide some clinical considerations in this high-risk population.

    Although the major targets of HIV infection are CD4+ T cells, dendritic cells (DC) represent a crucial subset in HIV infection as they influence viral transmission, target cell infection and antigen presentation of HIV antigens. DC are potent antigen presenting cells that can modulate anti-viral immune responses. Through secretion of inflammatory cytokines and interferons (IFN), DC also alter T cell proliferation and differentiation, participating in the immune dysregulation characteristic of chronic HIV infection. Their wide distribution in close proximity with the mucosal epithelia makes them one of the first cell types to encounter HIV during sexual transmission [1]. We will discuss here the multiple roles that DC play at different stages of HIV infection, emphasizing their relevance to HIV pathology and progression. PMID:24246474

    In epidemiologic studies, human immunodeficiency virus (HIV)-infected men on antiretroviral therapy (ART) are at higher risk of incident diabetes mellitus compared with women with similar treatment histories. We used metabolomics to determine whether a sex difference in plasma amino acids, acylcarnitines, and organic acids predictive of diabetes and impaired energy metabolism is present in HIV-infected persons on long-term ART.We enrolled 70 HIV-infected adults (43% women) on efavirenz, tenofovir, and emtricitabine (Atripla) with HIV-1 RNA <50 copies/mL for over 2 years. Half of the HIV-infected subjects were obese, and these were matched with 30 obese HIV-negative controls. All subjects had no history of diabetes, statin use, or heavy alcohol use. Fasting insulin sensitivity was measured using homeostatic model assessment 2 (HOMA2), and adipose tissue was measured using dual-energy x-ray absorptiometry (DEXA). Liquid chromatography/mass spectrometry was used to quantitate fasting plasma branched chain and aromatic amino acids predictive of incident diabetes, and C3 and C5 acylcarnitinines and organic acids indicative of impaired energy metabolism.HIV-infected women had more baseline risk factors for insulin resistance: women were older (46 vs 44 years) and had a longer ART duration (8.4 vs 5.1 years, P < 0.05 for both) compared with men but had similar CD4+ count (median 701 cells/μL), smoking and hepatic C prevalence, and body mass index (BMI) (median 30.3 kg/m).

    Antiretroviral therapy (ART) has led to dramatic improvements in the lives of HIV-infected persons. However, residual immune activation, which persists despite ART, is associated with increased risk of non-AIDS morbidities. Accumulating evidence shows that disruption of the gut mucosal epithelium during SIV/HIV infections allows translocation of microbial products into the circulation, triggering immune activation. This disruption is due to immune, structural and microbial alterations. In this review, we highlighted the key findings of gut mucosa studies of SIV-infected macaques and HIV-infected humans that have revealed virus-induced changes of intestinal CD4, CD8 T cells, innate lymphoid cells, myeloid cells, and of the local cytokine/chemokine network in addition to epithelial injuries. We review the interplay between the host immune response and the intestinal microbiota, which also impacts disease progression. Collectively, these studies have instructed clinical research on early ART initiation, modifiers of microbiota composition, and recombinant cytokines for restoring gut barrier integrity.

    Stigma has become a gendered phenomenon that affects increasing numbers of HIV-infected women worldwide. This study examined the role of age as a possible moderator of the relationship between stigma and antiretroviral therapy adherence, CD4% and viral load among 120 HIV-infected women. A secondary analysis was conducted using data from the Keeping Healthy and Active with Risk Reduction and Medication Adherence (KHARMA) Project, an National Institutes of Health (NIH) funded randomized controlled trial to improve Antiretroviral treatment (ART) adherence and reduce risky behaviors in HIV-infected women at five clinical sites in a South-eastern city from 2005 to 2008. Stigma was measured using the Perceived Personal Stigma of Human Immunodeficiency Virus and Acquired Immune Deficiency Syndrome (HIV/AIDS) scale. Among participants <50 years old (n=90), age was significantly associated with viral load (rho=−.24, p=.02) and stigma was negatively associated with CD4% (r =−.26, p=.02). For the 30 participants >50 years old, age was not significantly associated with viral load, stigma or CD4%, and there was no significant association between stigma and CD4% (r=.07, p=.70). These findings indicate the need for further study regarding this potential moderating effect and possible interventions to address the susceptibility of younger women to the harmful effects of stigma.

    'Puppets Against AIDS' is a novel educational medium being used to try to reduce the spread of HIV infection in South Africa. It involves the use of street theatre employing two-metre-high puppets who act out a story of how one person, who is infected with HIV, passes it onto a series of other people until he eventually dies. The puppet show was evaluated in two phases. The first involved a content analysis of a video recording of the show by a multidisciplinary group, according to a set of criteria for appropriate education on HIV infection. This show was found to be professional and comprehensive in terms of the educational messages provided. Some suggestions were made for improvements. The second phase was a before and after study of the impact on the audience at a series of live shows. The show made a significant contribution to knowledge and intended behaviour in the short term. Overall it was felt that the show does make a valuable contribution, but could be made more effective if incorporated into existing community-based education programmes on HIV infection.

    T-regulatory cell (T-reg) frequency is increased in HIV infection and with aging. We evaluated the effect of age on total, memory and naïve T-reg percentages in untreated HIV infection. Older HIV+ subjects had a total T-reg percent that is 2.8% (p = 0.02) higher than among younger HIV+, older HIV− and younger HIV− subjects. In HIV+ subjects, the total T-reg percentage is inversely correlated with the lymphocyte proliferative responses to tetanus (r = −0.45, p = 0.002) and Candida (r = −0.43, p =0.003) antigens. Similar correlations were seen between memory T-reg percentages and the lymphocyte proliferative response to tetanus and Candida in HIV+ subjects. T-reg percentages did not correlate consistently with markers of immune activation. T-reg percentages are increased in the older HIV+ population and may play a role in the accelerated disease progression seen in older HIV-infected persons. PMID:19008157

    To study the prevalence of oral manifestations, we examined 217 patients infected with the human immunodeficiency virus (HIV). Most of our patients were intravenous drug abusers (IVDAs) (65%). Other risk categories were represented by IVDAs who were also male homosexuals or bisexuals (11%), male homosexuals and bisexuals (16%), sexual partners of HIV-infected patients (5%), and hemophilic persons and recipients of blood transfusions (3%). Forty-six patients were women and 171 were men, with a median age of 27 years (range, 11 to 65 years). At the time of first examination, 38% of patients had asymptomatic HIV infection, 36% had lymphadenopathy syndrome, 17% had AIDS-related complex, and 9% had AIDS. Oral manifestations were observed in 89 (41%) patients. Of these, 15 had asymptomatic infection, 23 had lymphadenopathy syndrome, 27 had AIDS-related complex, and 24 had AIDS. Increasing severity of disease was significantly associated with higher prevalence of oral lesions (p less than or equal to 0.0001). Candidiasis was the most common oral lesion, followed by hairy leukoplakia. Kaposi's sarcoma, melanotic macules, herpes labialis, condyloma acuminatum, perioral molluscum contagiosum, and bacterial glossitis due to Escherichia coli infection were found in a small number of patients. Results of culture for fungi, available for 203 patients, revealed that 51% of patients with positive Candida cultures had clinical evidence of candidiasis. Our study demonstrates that oral lesions are also important signs of HIV infection among IVDAs. Early diagnosis of these manifestations is becoming increasingly significant in the practice of dentistry. PMID:2304743

Results Of 14 454 men meeting inclusion criteria, TRT was initiated in 1482 (10%) with an initiation rate of 19.7/1000 person-years [95% confidence interval (95% CI) 18.7–20.7]. In the multivariable model, TRT was significantly associated with age at least 35 years, white race, diagnosis of AIDS wasting, hepatitis C coinfection, protease inhibitor based antiretroviral therapy and nadir CD4+ cell count of 200 cells/µl or less. Overall, 1886 out of 14 454 (13%) had testosterone deficiency. Among those initiating TRT, 992 out of 1482 (67%) had a pre-TRT serum total testosterone measured, and deficiency [<300 ng/dl (10.4 nmol/l)] was found in 360 out of 1482 (24%). Post-TRT serum total testosterone was measured within 6 months of TRT initiation in 377 out of 1482 (25%) men. Conclusion TRT was common in HIV-infected men, though evidence for pre-TRT testosterone deficiency was lacking in 76%. Endocrine guidelines for post-TRT monitoring were uncommonly followed. Given cardiovascular and other risks associated with TRT, efforts should focus on understanding factors driving these TRT practices in HIV-infected men. PMID:25387318

    Emerging evidence suggests that CNS injury and neurocognitive impairment persist in the setting of chronic HIV infection and combination antiretroviral therapy (CART). Yet, whether neurological injury can progress in this setting remains uncertain. Magnetic resonance spectroscopy and neurocognitive and clinical assessments were performed over 2 years in 226 HIV-infected individuals on stable CART, including 138 individuals who were neurocognitively asymptomatic (NA). Concentrations of N-acetylaspartate (NAA), creatine (Cr), choline (Cho), myoinositol, and glutamate/glutamine (Glx) were measured in the midfrontal cortex (MFC), frontal white matter (FWM), and basal ganglia (BG). Longitudinal changes in metabolite levels were determined using linear mixed effect models, as were metabolite changes in relation to global neurocognitive function. HIV-infected subjects showed significant annual decreases in brain metabolite levels in all regions examined, including NAA (2.95 %) and Cho (2.61 %) in the FWM; NAA (1.89 %), Cr (1.84 %), Cho (2.19 %), and Glx (6.05 %) in the MFC; and Glx (2.80 %) in the BG. Similar metabolite decreases were observed in the NA and subclinically impaired subgroups, including subjects with virologic suppression in plasma and CSF. Neurocognitive decline was associated with longitudinal decreases in Glx in the FWM and the BG, and in NAA in the BG. Widespread progressive changes in the brain, including neuronal injury, occur in chronically HIV-infected persons despite stable antiretroviral treatment and virologic suppression and can lead to neurocognitive declines. The basis for these findings is poorly understood and warrants further study. PMID:23613008

    Background. Compliance with medication requires good sense of smell and taste. Objective. To evaluate the olfactory and gustatory function of HIV infected women in Ibadan, Nigeria. Methods. A case control study of women comprising 83 HIV infected women and 79 HIV uninfected women. Subjective self-rating of taste and smell function was by visual analogue scale. Olfactory function was measured via olfactory threshold (OT), olfactory discrimination (OD), olfactory identification (OI), and TDI using “Sniffin' sticks” kits and taste function (Total Taste Strips (TTS) score) measurement was by taste strips. Results. The mean age of the HIV infected women was 43.67 years ± 10.72 and control was 41.48 years ± 10.99. There was no significant difference in the self-reported assessment of smell (p = 0.67) and taste (p = 0.84) of HIV infected and uninfected women. Although the mean OT, OD, OI, TDI, and TTS scores of HIV infected and uninfected women were within the normosmic and normogeusic values, the values were significantly higher in the controls (p < 0.05). Hyposmia was in 39.7% of subjects and 12.6% of controls while hypogeusia was in 15.7% of subjects and 1.3% of controls. Conclusions. Hyposmia and hypogeusia are commoner among the HIV infected women than the HIV uninfected women and the risk increases with an increased duration of highly active antiretroviral therapy.

    With the advent of highly active antiretroviral agents, women with HIV infection can expect to live longer than ever before. This increased survival has led to concerns about the long-term implications of HIV disease and its treatment. Women with HIV infection appear to lose ovarian function earlier in life than women without HIV infection. They also have evidence of reduced bone mineral density and increased cardiovascular risk. Moreover, many of these increases in risk factors are present even prior to the menopausal transition. All of these risks, present at midlife, augur poorly for future health and describe a substantially increased burden of disease likely to accrue to HIV-infected women as they enter older age groups. Further compounding the adversity faced by the HIV infected, the demographics of women most vulnerable to this disease include adverse social and economic influences, both of which worsen their long-term prognosis. For example, drug use and poverty are related to more severe menopausal symptoms and chronic stress is related to worse psychological and cardiovascular risk. An understanding of how menopause interacts with HIV infection is therefore most important to alert the clinician to perform surveillance for common health problems in postmenopausal women, and to address directly and appropriately symptomatology during the menopausal transition.

    A longer life expectancy and a high prevalence of tobacco smoking among HIV patients have led to an increasing cumulative exposure to tobacco in this community. Clinical recommendations for smoking cessation in HIV patients are mainly based on the body of evidence from the general population plus few available data from HIV cohort studies. The assumption that the pathophysiology of tobacco-related diseases in HIV-infected patients is similar to that in the general population may be questionable. This article reviews the pathophysiological mechanisms underlying health problems attributable to tobacco in HIV patients, and how these mechanisms may interact with those of HIV infection. Tobacco smoking exerts a greater health impact on HIV-infected patients than on uninfected smokers. Components of tobacco smoke and HIV infection induce complex interrelated pathophysiological changes through different pathways, affecting various organ systems with a cumulative or synergistic effect. This review supports the contention that HIV infection may confer an increased susceptibility to the harmful effects of smoking. Tobacco-related harm in the setting of HIV infection is still underestimated. A better understanding of the pathophysiological interaction between tobacco smoking and HIV will help to promote smoking cessation in this specific population. PMID:25427101

    Purpose The purpose of this paper is to describe factors associated with incarceration as well as the association between recent incarceration and HIV-related sexual risk behaviors, access to insurance, healthcare utilization (emergency department (ED) and hospital use), antiretroviral therapy (ART) prescription, and viral suppression. Design/methodology/approach Using 2009-2010 data from a cross-sectional, nationally representative three-stage sample of HIV-infected adults receiving care in the USA, the authors assessed the demographic characteristics, healthcare utilization, and clinical outcomes of HIV-infected persons who had been recently incarcerated (detention for>24 hours in the past year) using bivariate analyses. The authors used multivariable logistic regression to examine associations of recent incarceration with insurance status as well as clinical and behavioral outcomes. Findings An estimated 22,949 (95 percent confidence interval (CI) 19,062-26,836) or 5.4 percent (CI: 4.7-6.1) of all HIV-infected persons receiving care were recently incarcerated. Factors associated with recent incarceration were age <50 years, being a smoker, having high school diploma or less, being homeless, income at or below the poverty guidelines, having a geometric mean of CD4 count <500 cells/ μL, and using drugs in the past 12 months. Results from multivariable modeling indicated that incarcerated persons were more likely to use ED services, and to have been hospitalized, and less likely to have achieved viral suppression. Originality/value Recent incarceration independently predicted worse health outcomes and greater use of emergency services among HIV-infected adults currently in HIV care. Options to improve the HIV continuum of care, including pre-enrollment for healthcare coverage and discharge planning, may lead to better health outcomes for HIV-infected inmates post-release.

    The challenge to rural nurses to deliver knowledgeable and skilled nursing and health care to individuals with HIV infection and AIDS is indeed tremendous. Isolation of rural communities and health care facilities coupled with limited resources, financial concerns, conservative values of many traditional rural communities, and the tendency to exclude those who do not conform to community norms make it difficult to integrate the individual with HIV disease into the rural health care delivery system fully. Issues of particular concern to the rural nurse include maintenance of client confidentiality, obtaining and maintaining current knowledge and skills necessary to the provision of quality HIV nursing care, management of complex client health care problems, and provision of appropriate support services. Rural nurses must be innovative and creative in developing mechanisms to deal with these concerns. In addition, because rural nurses are well respected by the community and viewed as possessing a great deal of expertise in the delivery of health care, they are well positioned to provide leadership to the community in developing educational and care strategies to more effectively provide HIV care. Indeed, the delivery of high-quality HIV care in rural areas across the United States will likely depend on the expertise and leadership provided by rural nurses. PMID:8451211

    Antiretroviral therapy (ART) for HIV is not a cure. However, recent studies suggest that ART, initiated early during primary infection, may induce post-treatment control (PTC) of HIV infection with HIV RNA maintained at <50 copies per mL. We investigate the hypothesis that ART initiated early during primary infection permits PTC by limiting the size of the latent reservoir, which, if small enough at treatment termination, may allow the adaptive immune response to prevent viral rebound (VR) and control infection. We use a mathematical model of within host HIV dynamics to capture interactions among target cells, productively infected cells, latently infectedmore » cells, virus, and cytotoxic T lymphocytes (CTLs). Analysis of our model reveals a range in CTL response strengths where a patient may show either VR or PTC, depending on the size of the latent reservoir at treatment termination. Below this range, patients will always rebound, whereas above this range, patients are predicted to behave like elite controllers. As a result, using data on latent reservoir sizes in patients treated during primary infection, we also predict population-level VR times for non-controllers consistent with observations.« less

    A 30-year-old homosexual Japanese man had fourteen days of fever, malaise, appetite loss, sore throat, and four days of diarrhea and slightly congested eyes before he developed a skin eruption. He presented with measles-like exanthems on his face, trunk, and extremities. Deep red enanthems were seen on his left buccal mucosa opposite the premolar teeth, and whitish enanthems were seen on the buccal and gingival mucosa. HIV RNA was detected at the high concentration of 5.8 x 10(6) copies /ml in his serum. Cerebrospinal fluid examination revealed aseptic meningitis with 5,488 copies /ml of HIV RNA. Anti-HIV 1 antibodies against Gp160 and p24 tested by Western blot assay showed seroconversion on day 5 of his admission, seven days after he developed the skin eruptions. The fever lasted for three weeks from the initial onset, and the skin eruptions lasted for twelve days. Histopathologically, a mononuclear cell infiltration was seen mainly in the upper dermis surrounding small vessels and sweat ducts, with CD8+ cytotoxic T lymphocytes predominant. Additionally, CD1a+ putative interdigitating dendritic cells had also infiltrated perivascularly, and were surrounded by CD8+ and CD4+ T cells. In situ hybridization study failed to detect HIV products in skin biopsy specimens. Our findings suggested that CD8+ T cells and their interaction with CD1a+ dendritic cells in the skin may be important in inducing skin manifestations in acute HIV infections. PMID:15906546

    Suboptimal adherence, toxicity, drug resistance and viral reservoirs make the lifelong treatment of HIV infection challenging. The emerging field of nanotechnology may play an important role in addressing these challenges by creating drugs that possess pharmacological advantages arising out of unique phenomena that occur at the “nano” scale. At these dimensions, particles have physicochemical properties that are distinct from those of bulk materials or single molecules or atoms. In this review, basic concepts and terms in nanotechnology are defined, and examples are provided of how nanopharmaceuticals such as nanocrystals, nanocapsules, nanoparticles, solid lipid nanoparticles, nanocarriers, micelles, liposomes and dendrimers have been investigated as potential anti-HIV therapies. Such drugs may, for example, be used to optimize the pharmacological characteristics of known antiretrovirals, deliver anti-HIV nucleic acids into infected cells or achieve targeted delivery of antivirals to the immune system, brain or latent reservoirs. Also, nanopharmaceuticals themselves may possess anti-HIV activity. However several hurdles remain, including toxicity, unwanted biological interactions and the difficulty and cost of large-scale synthesis of nanopharmaceuticals. PMID:22590683

    Since the introduction of highly active antiretroviral therapy there has been an improvement in the quality of life for people with HIV infection. Despite the progress made, about 70% of HIV patients develop neurologic complications. These originate either in the central or the peripheral nervous system (Sacktor, 2002). These neurologic disorders are divided into primary and secondary disorders. The primary disorders result from the direct effects of the virus and include HIV-associated neurocognitive disorder (HAND), HIV-associated vacuolar myelopathy (VM), and distal symmetric polyneuropathy (DSP). Secondary disorders result from marked immunosuppression and include opportunistic infections and primary central nervous system lymphoma (PCNSL). A differential diagnosis which can be accomplished by detailed history, neurologic examination, and by having a good understanding of the role of HIV in various neurologic disorders will help physicians in approaching these problems. The focus of this chapter is to discuss neuropathogenesis of HIV, the various opportunistic infections, primary CNS lymphoma, neurosyphilis, CNS tuberculosis, HIV-associated peripheral neuropathies, HIV-associated neurocognitive disorder (HAND), and vacuolar myelopathy (VM). It also relies on the treatment recommendations and guidelines for the above mentioned neurologic disorders proposed by the US Centers for Disease Control and Prevention (CDC) and the Infectious Diseases Society of America.

    Variability to HIV infection, its progression as well as responsiveness to antiretroviral therapy (ART) is observed among individuals including viraemia controllers or exposed uninfected, rapid versus slow progressors and ART responders compared to non responders. This differential responsiveness/vulnerability to HIV-1 is governed by multiple host genetic factors that include HLA, cytokines, chemokines, their receptors and others. This review highlights the influence of these genetic factors on HIV/AIDS outcome; however, in India, the information in this area is very limited and most of these genetic studies have been conducted in Caucasian and South African populations. Considering, the population specific differences in the frequencies of protective or susceptibility favouring alleles and their influence on the disease outcome, it is of utmost importance to strengthen ongoing efforts towards defining largely unknown genetic propensity in Indian population, particularly by recruitment of large cohorts of well categorized exposed uninfected individuals, rapid, long term non progressors and elite viraemic controllers. Multi-parametric analysis of these potentially interactive immunogenetic variables in these cohorts may help to define potential targets for diagnostics and therapy in a population specific manner.

    Background Higher levels of small low-density lipoprotein (LDL) and lower levels of high-density lipoprotein (HDL) subclasses have been associated with increased risk of cardiovascular disease. The extent to which HIV infection and HIV/HCV coinfection are associated with abnormalities of lipoprotein subclasses is unknown. Methods Lipoprotein subclasses were measured by nuclear magnetic resonance (NMR) spectroscopy in plasma samples from 569 HIV-infected and 5948 control participants in the FRAM, CARDIA and MESA studies. Multivariable regression was used to estimate the association of HIV and HIV/HCV coinfection with lipoprotein measures with adjustment for demographics, lifestyle factors, and waist-to-hip ratio. Results Relative to controls, small LDL levels were higher in HIV-monoinfected persons (+381 nmol/L, p<.0001), with no increase seen in HIV/HCV coinfection (−16.6 nmol/L). Levels of large LDL levels were lower (−196 nmol/L, p<.0001) and small HDL were higher (+8.2 μmol/L, p<.0001) in HIV-monoinfection with intermediate values seen in HIV/HCV-coinfection. Large HDL levels were higher in HIV/HCV-coinfected persons relative to controls (+1.70 μmol/L, p<.0001), whereas little difference was seen in HIV-monoinfected persons (+0.33, p=0.075). Within HIV-infected participants, HCV was associated independently with lower levels of small LDL (−329 nmol/L, p<.0001) and small HDL (−4.6 μmol/L, p<.0001), even after adjusting for demographic and traditional cardiovascular risk factors. Conclusion HIV-monoinfected participants had worse levels of atherogenic LDL lipoprotein subclasses compared with controls. HIV/HCV coinfection attenuates these changes, perhaps by altering hepatic factors affecting lipoprotein production and/or metabolism. The effect of HIV/HCV coinfection on atherosclerosis and the clinical consequences of low small subclasses remain to be determined. PMID:24136113

    Limited information is available about the effects of HIV and subsequent antiretroviral treatment on host-microbe interactions. This study aimed to determine the salivary microbial composition for 10 HIV-seropositive subjects, before and 6 months after highly active antiretroviral therapy (HAART), compared with that for 10 HIV-seronegative subjects. A conventional culture and two culture-independent analyses were used and consistently demonstrated differences in microbial composition among the three sets of samples. HIV-positive subjects had higher levels of total cultivable microbes, including oral streptococci, lactobacilli, Streptococcus mutans, and Candida, in saliva than did HIV-negative subjects. The total cultivable microbial levels were significantly correlated with CD4+ T cell counts. Denaturing gradient gel electrophoresis (DGGE), which compared the overall microbial profiles, showed distinct fingerprinting profiles for each group. The human oral microbe identification microarray (HOMIM) assay, which compared the 16S rRNA genes, showed clear separation among the three sample groups. Veillonella, Synergistetes, and Streptococcus were present in all 30 saliva samples. Only minor changes or no changes in the prevalence of Neisseria, Haemophilus, Gemella, Leptotrichia, Solobacterium, Parvimonas, and Rothia were observed. Seven genera, Capnocytophaga, Slackia, Porphyromonas, Kingella, Peptostreptococcaceae, Lactobacillus, and Atopobium, were detected only in HIV-negative samples. The prevalences of Fusobacterium, Campylobacter, Prevotella, Capnocytophaga, Selenomonas, Actinomyces, Granulicatella, and Atopobium were increased after HAART. In contrast, the prevalence of Aggregatibacter was significantly decreased after HAART. The findings of this study suggest that HIV infection and HAART can have significant effects on salivary microbial colonization and composition. PMID:24523469

    Introduction: Couples’ voluntary HIV counseling and testing (CHTC) is an HIV risk reduction strategy not widely available in the US. Methods: We assessed willingness to participate in CHTC among US HIV-infected clinic patients via tablet-based survey and among HIV-negative persons with HIV-infected partners in care via mixed-method phone interviews. Results: Most of the N=64 HIV-infected partners surveyed were men (89%), on antiretroviral treatment (ART) (92%), and many self-identified homosexual (62%). We observed high levels of willingness to participate in CHTC (64%) among HIV-infected partners. Reasons for not wanting to participate included perceived lack of need (26%), desire to self-disclose their status (26%), and fear of being asked sensitive questions with their partner present (17%). HIV-infected partners were interested in discussing ART (48%), other sexually transmitted infections (STIs) (44%), and relationship agreements like monogamy (31%) during CHTC sessions. All N=15 HIV-negative partners interviewed were men, most identified as homosexual (73%), and about half (54%) reported consistent condom use with HIV-infected partners. We observed high levels of willingness to participate in CHTC (87%) among HIV-negative partners, who were also interested in discussing ART (47%), other STIs (47%), mental health services (40%), and relationship agreements (33%). Most negative partners (93%) indicated that they believed their HIV-infected partner was virally suppressed, but in the event that they were not, many (73%) were willing to take pre-exposure prophylaxis (PrEP). Conclusion: These results indicate that CHTC for serodiscordant couples is acceptable and should emphasize aspects most pertinent to these couples, such as discussion of ART/PrEP, STIs, and relationship agreements.

    Individuals with HIV infection are living substantially longer on antiretroviral therapy, but hospitalization rates continue to be relatively high. We do not know how overall or diagnosis-specific hospitalization rates compare between HIV-infected and uninfected individuals or what conditions may drive hospitalization trends. Hospitalization rates among United States Veterans were calculated and stratified by HIV serostatus and principal diagnosis disease category. Because alcohol-related diagnoses (ARD) appeared to have a disproportional effect, we further stratified our calculations by ARD history. A multivariable Cox proportional hazards model was fitted to assess the relative risk of hospitalization controlling for demographic and other comorbidity variables. From 1997 to 2011, 46,428 HIV-infected and 93,997 uninfected patients were followed for 1,497,536 person-years. Overall hospitalization rates decreased among HIV-infected and uninfected patients. However, cardiovascular and renal insufficiency admissions increased for all groups while gastrointestinal and liver, endocrine, neurologic, and non-AIDS cancer admissions increased among those with an alcohol-related diagnosis. After multivariable adjustment, HIV-infected individuals with an ARD had the highest risk of hospitalization (hazard ratio 3.24, 95 % CI 3.00, 3.49) compared to those free of HIV infection and without an ARD. Still, HIV alone also conferred increased risk (HR 2.08, 95 % CI 2.04, 2.13). While decreasing overall, risk of all-cause hospitalization remains higher among HIV-infected than uninfected individuals and is strongly influenced by the presence of an ARD. PMID:25711299

    Talaromyces (Penicillium) marneffei is an important pathogenic thermally dimorphic fungus causing systemic mycosis in Southeast Asia. The clinical significance of T. marneffei became evident when the human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome epidemic arrived in Southeast Asia in 1988. Subsequently, a decline in the incidence of T. marneffei infection among HIV-infected patients was seen in regions with access to highly active antiretroviral therapy and other control measures for HIV. Since the 1990s, an increasing number of T. marneffei infections have been reported among non-HIV-infected patients with impaired cell-mediated immunity. Their comorbidities included primary adult-onset immunodeficiency due to anti-interferon-gamma autoantibodies and secondary immunosuppressive conditions including other autoimmune diseases, solid organ and hematopoietic stem cell transplantations, T-lymphocyte-depleting immunsuppressive drugs and novel anti-cancer targeted therapies such as anti-CD20 monoclonal antibodies and kinase inhibitors. Moreover, improved immunological diagnostics identified more primary immunodeficiency syndromes associated with T. marneffei infection in children. The higher case-fatality rate of T. marneffei infection in non-HIV-infected than HIV-infected patients might be related to delayed diagnosis due to the lack of clinical suspicion. Correction of the underlying immune defects and early use of antifungals are important treatment strategies. Clinicians should be familiar with the changing epidemiology and clinical management of T. marneffei infection among non-HIV-infected patients. PMID:26956447

    This study investigated the psychological impact of HIV infection through assessment of posttraumatic stress disorder in response to HIV infection. Sixty-one HIV-positive homosexual/bisexual men were assessed for posttraumatic stress disorder in response to HIV infection (PTSD-HIV) using a modified PTSD module of the DIS-III-R. Thirty percent met criteria for a syndrome of posttraumatic stress disorder in response to HIV diagnosis (PTSD-HIV). In over one-third of the PTSD cases, the disorder had an onset greater than 6 months after initial HIV infection diagnosis. PTSD-HIV was associated with other psychiatric diagnoses, particularly the development of first episodes of major depression after HIV infection diagnosis. PTSD-HIV was significantly associated with a pre-HIV history of PTSD from other causes, and other pre-HIV psychiatric disorders and neuroticism scores, indicating a similarity with findings in studies of PTSD from other causes. The findings from this preliminary study suggest that a PTSD response to HIV diagnosis has clinical validity and requires further investigation in this population and other medically ill groups. The results support the inclusion of the diagnosis of life-threatening illness as a traumatic incident that may lead to a posttraumatic stress disorder, which is consistent with the DSM-IV criteria.

    Talaromyces (Penicillium) marneffei is an important pathogenic thermally dimorphic fungus causing systemic mycosis in Southeast Asia. The clinical significance of T. marneffei became evident when the human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome epidemic arrived in Southeast Asia in 1988. Subsequently, a decline in the incidence of T. marneffei infection among HIV-infected patients was seen in regions with access to highly active antiretroviral therapy and other control measures for HIV. Since the 1990s, an increasing number of T. marneffei infections have been reported among non-HIV-infected patients with impaired cell-mediated immunity. Their comorbidities included primary adult-onset immunodeficiency due to anti-interferon-gamma autoantibodies and secondary immunosuppressive conditions including other autoimmune diseases, solid organ and hematopoietic stem cell transplantations, T-lymphocyte-depleting immunsuppressive drugs and novel anti-cancer targeted therapies such as anti-CD20 monoclonal antibodies and kinase inhibitors.

    In this paper, we review serological and molecular based methods to identify HIV infection recency. The accurate identification of recent HIV infection continues to be an important research area and has implications for HIV prevention and treatment interventions. Longitudinal cohorts that follow HIV negative individuals over time are the current gold standard approach, but they are logistically challenging, time consuming and an expensive enterprise. Methods that utilize cross-sectional testing and biomarker information have become an affordable alternative to the longitudinal approach. These methods use well-characterized biological makers to differentiate between recent and established HIV infections. However, recent results have identified a number of limitations in serological based assays that are sensitive to the variability in immune responses modulated by HIV subtypes, viral load and antiretroviral therapy. Molecular methods that explore the dynamics between the timing of infection and viral evolution are now emerging as a promising approach. The combination of serological and molecular methods may provide a good solution to identify recent HIV infection in cross-sectional data. As part of this review, we present the advantages and limitations of serological and molecular based methods and their potential complementary role for the identification of HIV infection recency.

    The advent of combination antiretroviral drug regimens has transformed HIV infection from a fatal illness into a manageable chronic condition. All patients with HIV infection should be considered for antiretroviral therapy, regardless of CD4 count or HIV viral load, for individual benefit and to prevent HIV transmission. Antiretroviral drugs affect HIV in several ways: entry inhibitors block HIV entry into CD4 T cells; nucleotide and nucleoside reverse transcriptase inhibitors prevent reverse transcription from RNA to DNA via chain-terminating proteins; nonnucleoside reverse transcriptase inhibitors prevent reverse transcription through enzymatic inhibition; integrase strand transfer inhibitors block integration of viral DNA into cellular DNA; protease inhibitors block maturation and production of the virus. Current guidelines recommend six combination regimens for initial therapy. Five are based on tenofovir and emtricitabine; the other uses abacavir and lamivudine. Five include integrase strand transfer inhibitors. HIV specialists should assist with treating patients with complicated HIV infection, including patients with treatment-resistant HIV infection, coinfection with hepatitis B or C virus, pregnancy, childhood infections, severe opportunistic infections, complex drug interactions, significant drug toxicity, or comorbidities. Family physicians can treat most patients with HIV infection effectively by choosing appropriate treatment regimens, monitoring patients closely, and retaining patients in care. PMID:27092564

    Synopsis The smoking prevalence estimates among HIV-infected individuals range from 40%-84%; much higher than the overall adult prevalence in the United States. Characteristics that are associated with smokers who are HIV-positive include drug and alcohol abuse, psychiatric comorbidities, and lower education and socioeconomic status. There are important health implications for HIV-infected smokers, including bacterial and Pneumocystis pneumonia, tuberculosis, COPD, lung cancer and coronary artery disease. To date, there have been few tobacco dependence treatment trials conducted among HIV-infected smokers. Most have used nicotine replacement therapy but abstinence rates were low. A recent preliminary study found the use of varenicline to be well tolerated and it may increase abstinence rates with HIV-infected individuals. Recommendations for future research include examining underlying factors that contribute to persistent smoking and barriers to abstinence, identifying ways to increase motivation for quit attempts, increasing the number of multi-centered, two-arm tobacco dependence treatment trials, and using highly efficacious first-line pharmacotherapy in tobacco dependence treatment intervention studies. Addressing the above-mentioned research gaps will help to reduce the tobacco-related disease burden of HIV-infected individuals in the future. PMID:23702169

    Objectives .- To ascertain the suitability of HIV-positive individuals for insurance coverage based on international data and practices. Background .- During the first decade of HIV epidemic, diagnosis of HIV-infection carried a poor prognosis. Since the introduction of Highly Active Anti-Retroviral Therapy (HAART or ART), HIV infection is more like other chronic diseases with infected individuals often living 20 or more years after the diagnosis of HIV infection Methods .- Review of peer-reviewed publications was undertaken to assess the risk of death in the HIV-infected population as a whole as well as subsets with favorable outcomes and those with additional comorbidities, such as co-infection with hepatitis viruses and drug use. Results .- Review of literature revealed that in well-educated, non-drug using individuals, negative for hepatitis B and C infection, who had CD 4 counts above 500/cmm, viral loads below 500 particles/mL, and were compliant with treatment, the mortality rate was similar to that of general population. Conclusions .- The risk of death, in at least a subset of HIV-positive subjects, is low enough that insurance providers should consider stratifying HIV-infected individuals according to mortality risk and offering insurance rates comparable to people with other diseases with similar mortality risks.

    SUMMARY A study of HIV-infected persons in primary care in four U.S. found that 13% had a prevalent STD at enrollment and 7% an incident STD six months later. Background To better understand the factors associated with HIV and STD transmitting behavior among HIV-infected persons, we estimated STD prevalence and incidence and associated risk factors among a diverse sample of HIV-infected patients in primary care. Methods We analyzed data from 557 participants in the SUN study, a prospective observational cohort of HIV-infected persons in primary care in four U.S. cities. At enrollment and six months thereafter, participants completed an audio computer-assisted self interview about their sexual behavior, and were screened for genitourinary, rectal and pharyngeal N. gonorrhoeae and C. trachomatis infections by nucleic acid amplification testing, and for serologic evidence of syphilis. Women provided cervicovaginal samples and men provided urine to screen for T. vaginalis by polymerase chain reaction. Results Thirteen percent of participants had a prevalent STD at enrollment and 7% an incident STD six months later. The most commonly diagnosed infections were rectal chlamydia, oropharyngeal gonorrhea, and chlamydial urethritis among the men, and trichomoniasis among the women. Other than trichomoniasis, 94% of incident STDs were identified in MSM. Polysubstance abuse other than marijuana, and having ≥ 4 sex partners in the six months prior to testing were associated with diagnosis of an incident STD. Conclusions STDs were commonly diagnosed among contemporary HIV-infected patients receiving routine outpatient care, particularly among sexually active MSM who used recreational drugs. These findings underscore the need for frequent STD screening, prevention counseling, and substance abuse treatment for HIV-infected persons in care. PMID:22183836

    Although increasing attention has been paid to the use of dental care by HIV patients, the existing studies do not use probability samples, and no accurate population estimates of use can be made from this work. The intent of the present study was to establish accurate population estimates of the use of dental services by patients under medical care. The study, part of the HIV Cost and Services Utilization Study (HCSUS), created a representative national probability sample, the first of its kind, of HIV-infected adults in medical care. Both bivariate and logistic regressions were conducted, with use of dental care in the preceding 6 months as the dependent variable and demographic, social, behavioral, and disease characteristics as independent variables. Forty-two percent of the sample had seen a dental health professional in the preceding 6 months. The bivariate logits for use of dental care show that African-Americans, those whose exposure to HIV was caused by hemophilia or blood transfusions, persons with less education, and those who were employed were less likely to use dental care (p < 0.05). Sixty-five percent of those with a usual source of care had used dental care in the preceding 6 months. Use was greatest among those obtaining dental care from an AIDS clinic (74%) and lowest among those without a usual source of dental care (12%). We conclude that, in spite of the high rate of oral disease in persons with HIV, many do not use dental care regularly, and that use varies by patient characteristics and availability of a regular source of dental care.

    Background Perceived discrimination in clinical settings could discourage HIV-infected people from seeking health care, adhering to treatment regimens, or returning for follow-up. Objectives This study aims to determine whether HIV-infected people perceive that physicians and other health care providers have discriminated against them. Design, Participants Cross-sectional data (1996 to 1997) from the HIV Cost and Services Utilization Study (HCSUS), which conducted in-person interviews with a nationally representative probability sample of 2,466 HIV-infected adults receiving health care within the contiguous U.S. Measurements Reports of whether health care providers have been uncomfortable with the respondent, treated the respondent as an inferior, preferred to avoid the respondent, or refused the respondent service. Questions also covered the types of providers who engaged in these behaviors. Results Twenty-six percent of HIV-infected adults receiving health care reported experiencing at least 1 of 4 types of perceived discrimination by a health care provider since becoming infected with HIV, including 8% who had been refused service. White respondents (32%) were more likely than others (27%) and Latinos (21%) and nearly twice as likely as African Americans (17%) to report perceived discrimination (P<.001). Respondents whose first positive HIV test was longer ago were also more likely to report discrimination (P<.001). Respondents who reported discrimination attributed it to physicians (54%), nurses and other clinical staff (39%), dentists (32%), hospital staff (31%), and case managers or social workers (8%). Conclusions Many HIV-infected adults believe that their clinicians have discriminated against them. Clinicians should make efforts to address circumstances that lead patients to perceive discrimination, whether real or imagined. PMID:16117747

    With the advent of antiretroviral therapy and improved access to care, the average life expectancy of patients with HIV infection receiving optimal treatment approaches that of patients in the general population. AIDS-related opportunistic infections and malignancies are no longer the primary issues; instead, traditional age- and lifestyle-related conditions are a growing concern. Patients with HIV infection are at higher risk of cardiovascular disease, diabetes, hypertension, and some non-AIDS-related cancers than patients in the general population. Family physicians need to be knowledgeable about screening for and managing chronic comorbid conditions as this population ages. Health maintenance, including appropriate vaccinations, prophylaxis against opportunistic infections, and routine screening for sexually transmitted infections, remains an important part of care. As HIV infection becomes a chronic condition, emerging strategies in prevention, including preexposure prophylaxis, fall within the scope of practice of the family physician. PMID:27092565

    Adolescents may come from family settings that heighten their vulnerability to early sexual initiation, promiscuity and sexual exploitation. To illuminate how this may occur, we present a set of five representative cases of HIV-infected females from a sample of 26 adolescent and young adult HIV-infected females (ages 16–24) enrolled in a study about the adaptive challenges people their age faced living with the disease. Study participants were recruited from five New York City adolescent HIV clinics that provided comprehensive specialty medical and supportive ancillary social services to adolescents and young adults with HIV. Study participants completed a battery of standardizes measures, using ACASI, and participated in a semi-structured in-depth interview. Using the qualitative interview data, we illustrate how early life and family circumstances including neglectful or dysfunctional parenting (e.g., low parental supervision), sexual abuse, and unstable housing placed these young women on a risk trajectory for HIV infection.

    Renal disease is a common complication of HIV-infected patients, associated with increased risk of cardiovascular events, progression to AIDS, AIDS-defining illness, and mortality. Early and accurate identification of renal disease is therefore crucial to improve patient outcomes. The use of serum creatinine, along with proteinuria, to detect renal involvement is essentially to screen for markers of glomerular disease and may not be effective in detecting earlier stages of renal injury. Therefore, more sensitive and specific markers are needed in order to early identify HIV-infected patients at risk of renal disease. This review article summarizes some new and important urinary markers of tubular injury in HIV-infected patients and their clinical usefulness in the renal safety follow-up of TDF-treated patients.

    Skeletal muscle mitochondrial dysfunction may contribute to low aerobic capacity. We previously reported 40% lower aerobic capacity in HIV-infected men compared to noninfected age-matched men. The objective of this study was to compare skeletal muscle mitochondrial enzyme activities in HIV-infected men on antiretroviral therapy (55 ± 1 years of age, n = 10 African American men) with age-matched controls (55 ± 1 years of age, n = 8 Caucasian men), and determine their relationship with aerobic capacity. Activity assays for mitochondrial function including enzymes involved in fatty acid activation and oxidation, and oxidative phosphorylation, were performed in homogenates prepared from vastus lateralis muscle. Hydrogen peroxide (H2O2), cardiolipin, and oxidized cardiolipin were also measured. β-hydroxy acyl-CoA dehydrogenase (β-HAD) (38%) and citrate synthase (77%) activities were significantly lower, and H2O2 (1.4-fold) and oxidized cardiolipin (1.8-fold) were significantly higher in HIV-infected men. VO2peak (mL/kg FFM/min) was 33% lower in HIV-infected men and was directly related to β-HAD and citrate synthase activity and inversely related to H2O2 and oxidized cardiolipin. Older HIV-infected men have reduced oxidative enzyme activity and increased oxidative stress compared to age-matched controls. Further research is crucial to determine whether an increase in aerobic capacity by exercise training will be sufficient to restore mitochondrial function in older HIV-infected individuals.

    Despite the increased frequency of recurrent pneumonia in HIV-infected patients and recent studies linking the airway bacterial community (microbiota) to acute and chronic respiratory infection, little is known of the oral and airway microbiota that exist in these individuals and their propensity to harbor pathogens despite antimicrobial treatment for acute pneumonia. This pilot study compared paired samples of the oral and airway microbiota from 15 hospitalized HIV-infected patients receiving antimicrobial treatment for acute pneumonia. Total DNA was extracted, bacterial burden was assessed by quantitative PCR, and amplified 16S rRNA was profiled for microbiome composition using a phylogenetic microarray (16S rRNA PhyloChip). Though the bacterial burden of the airway was significantly lower than that of the oral cavity, microbiota in both niches were comparably diverse. However, oral and airway microbiota exhibited niche specificity. Oral microbiota were characterized by significantly increased relative abundance of multiple species associated with the mouth, including members of the Bacteroides, Firmicutes, and TM7 phyla, while airway microbiota were primarily characterized by a relative expansion of the Proteobacteria. Twenty-two taxa were detected in both niches, including Streptococcus bovis and Chryseobacterium species, pathogens associated with HIV-infected populations. In addition, we compared the airway microbiota of five of these patients to those of five non-HIV-infected pneumonia patients from a previous study. Compared to the control population, HIV-infected patients exhibited relative increased abundance of a large number of phylogenetically distinct taxa, which included several known or suspected pathogenic organisms, suggesting that recurrent pneumonia in HIV-infected populations may be related to the presence of these species.

    The oral microbial community (microbiota) plays a critical role in human health and disease. Alterations in the oral microbiota may be associated with disorders such as gingivitis, periodontitis, childhood caries, alveolar osteitis, oral candidiasis and endodontic infections. In the immunosuppressed population, the spectrum of potential oral disease is even broader, encompassing candidiasis, necrotizing gingivitis, parotid gland enlargement, Kaposi's sarcoma, oral warts and other diseases. Here, we used 454 pyrosequencing of bacterial 16S rRNA genes to examine the oral microbiome of saliva, mucosal and tooth samples from HIV-positive and negative children. Patient demographics and clinical characteristics were collected from a cross-section of patients undergoing routine dental care. Multiple specimens from different sampling sites in the mouth were collected for each patient. The goal of the study was to observe the potential diversity of the oral microbiota among individual patients, sample locations, HIV status and various dental characteristics. We found that there were significant differences in the microbiome among the enrolled patients, and between sampling locations. The analysis was complicated by uneven enrollment in the patient cohorts, with only five HIV-negative patients enrolled in the study and by the rapid improvement in the health of HIV-infected children between the time the study was conceived and completed. The generally good oral health of the HIV-negative patients limited the number of dental plaque samples that could be collected. We did not identify significant differences between well-controlled HIV-positive patients and HIV-negative controls, suggesting that well-controlled HIV-positive patients essentially harbor similar oral flora compared to patients without HIV. Nor were significant differences in the oral microbiota identified between different teeth or with different dental characteristics. Additional studies are needed to better

    Objective WHO guidance recommends antiretroviral therapy (ART) initiation for all persons with a known HIV-uninfected partner, as a strategy to prevent HIV transmission. Uptake of ART among HIV-infected partners in serodiscordant partnerships is not known, which we evaluated in African HIV serodiscordant couples. Design Prospective cohort study. Methods Among HIV-infected persons from Kenya and Uganda who had a known heterosexual HIV-uninfected partner, we assessed ART initiation in those who became ART-eligible under national guidelines during follow-up. Participants received quarterly clinical and semi-annual CD4 monitoring, and active referral for ART upon becoming eligible. Results Of 1958 HIV-infected ART-eligible partners, 58% were women and the median age was 34 years. At the first visit when determined to be ART eligible, the median CD4 count was 273 cells/μL (IQR 221, 330), 77% had WHO stage 1 or 2 HIV disease, and 96% were receiving trimethoprim-sulfamethoxazole prophylaxis. The cumulative probabilities of initiating ART at 6, 12, and 24 months after eligibility were 49.9%, 70.0% and 87.6%, respectively. Younger age (<25 years) (adjusted hazard ratio [AHR] 1.39, p=0.001), higher CD4 count (AHR 1.95, p<0.001 for >350 compared with <200 cells/μL), higher education (AHR 1.25, p<0.001), and lack of income (AHR 1.15, p=0.02) were independent predictors for delay in ART initiation. Conclusions In the context of close CD4 monitoring, ART counseling, and active linkage to HIV care, a substantial proportion of HIV-infected persons with a known HIV-uninfected partner delayed ART initiation. Strategies to motivate ART initiation are needed, particularly for younger persons with higher CD4 counts. PMID:24798765

    Objective: To describe the prevalence and association of sexual risk behaviours and viral suppression among HIV-infected adults in the United States. Design: Cross-sectional analysis of weighted data from a probability sample of HIV-infected adults receiving outpatient medical care. The facility and patient response rates were 76 and 51%, respectively. Methods: We analysed 2009 interview and medical record data. Sexual behaviours were self-reported in the past 12 months. Viral suppression was defined as all viral load measurements in the medical record during the past 12 months less than 200 copies/ml. Results: An estimated 98 022 (24%) HIV-infected adults engaged in unprotected vaginal or anal sex; 50 953 (12%) engaged in unprotected vaginal or anal sex with at least one partner of negative or unknown HIV status; 23 933 (6%) did so while not virally suppressed. Persons who were virally suppressed were less likely than persons who were not suppressed to engage in vaginal or anal sex [prevalence ratio, 0.88; 95% confidence interval (CI), 0.82–0.93]; unprotected vaginal or anal sex (prevalence ratio, 0.85; 95% CI, 0.73–0.98); and unprotected vaginal or anal sex with a partner of negative or unknown HIV status (prevalence ratio, 0.79; 95% CI, 0.64–0.99). Conclusion: The majority of HIV-infected adults receiving medical care in the U.S. did not engage in sexual risk behaviours that have the potential to transmit HIV, and of the 12% who did, approximately half were not virally suppressed. Persons who were virally suppressed were less likely than persons who were not suppressed to engage in sexual risk behaviours. PMID:25000558

    The HIV infection dynamics is discussed in detail with a 3-dimensional cellular automata model in this paper. The model can reproduce the three-phase development, i.e., the acute period, the asymptotic period and the AIDS period, observed in the HIV-infected patients in a clinic. We show that the 3D HIV model performs a better robustness on the model parameters than the 2D cellular automata. Furthermore, we reveal that the occurrence of a perpetual source to successively generate infectious waves to spread to the whole system drives the model from the asymptotic state to the AIDS state.

    From the blood culture of an HIV-positive patient with a febrile syndrome (CD4 count 385 cells/microL and viral load nondetectable), Brucella canis was isolated. The patient was presumptively infected from his dogs, which tested positive, and showed good outcome after the therapy with doxycycline-ciprofloxacin, and the HIV infection would seem not to have been influenced by brucellosis. To our knowledge, no other case of B. canis in the setting of HIV infection has been reported in the literature, and the emerging zoonotic potential of the disease in urban areas should be considered.

    The complete caries removal of deep/extensive dentin carious lesions with conventional procedures (high- and low-speed bur) may increase the risk of pulp exposure. In children with systemic diseases, such as HIV-infected children, the dental treatment proposed for the primary dentition with pulp involvement is tooth extraction once endodontic therapies cannot be guaranteed successfully. Therefore, the objective of this study was to describe 3 cases of alternative techniques for caries removal in extensive and/or deep dentin carious lesions in the primary dentition of HIV-infected children: (1) atraumatic restorative treatment (ART); (2) Carisolv; and (3) Papacarie.

    Loss of IL-17-producing cells in the gut during HIV infection is linked to GI barrier damage. Kløverpris et al. (2016) find that circulating ILCs are lost early and irreversibly during HIV infection. Early ART administration protects against the ILC loss, and this might be clinically beneficial to HIV-infected individuals. PMID:26885853

    Limited data exist on whether sexual partner notification practices among HIV-infected men, particularly those who have sex with men (MSM), vary by HIV viral load. We examined factors associated with complete (all partners) vs. incomplete partner notification in 760 HIV-infected individuals across the United States, 49% of whom were MSM. Thirty-four percent reported incomplete partner notification. Incomplete partner notification was more likely among black men, MSM, and those reporting casual partners and non-condom use. Partner notification practices did not vary by HIV viral load except among those with casual partners in whom a detectable viral load was associated with incomplete partner notification. Increased sexual partner notification among HIV-infected men, especially MSM, is needed. PMID:24858394

    During 1999-2000, South Carolina's Department of Corrections (SCDC), Department of Health and Environmental Control (DHEC), and CDC investigated an outbreak of drug-susceptible tuberculosis (TB) that occurred in a state correctional facility housing human immunodeficiency virus (HIV)-infected inmates. All culture-confirmed case-patients have been linked by IS6110-based DNA fingerprinting of Mycobacterium tuberculosis isolates. This report describes the outbreak investigation and illustrates the need for increased vigilance for TB in settings in which HIV-infected persons congregate. PMID:11105766

    OBJECTIVE To analyze women’s perceptions and coping regarding the discovery of an HIV infection. METHODS A qualitative study in an HIV/AIDS Specialist Helpdesk in Recife, PE, Northeastern Brazil, from January to September 2010, involving eight women living with asymptomatic HIV aged between 27 and 37 years, without criteria for diagnosis of AIDS infected through intercourse and monitored by the service for at least one year. Forms were used to characterize the clinical situation and semi-structured interviews to understand perceptions and feelings related to personal trajectory after diagnosis and different ways of facing the diagnosis in family and social life. Content analysis was performed as suggested by Bardin. RESULTS The thematic category that emerged was stigma and discrimination. The women had life trajectories marked by stigma, which was perceived as discrimination after the diagnosis and in the experiences of everyday life. The revelation of the infection was perceived as limiting to a normal life, leading to the need to conceal the diagnosis. The discriminatory attitudes of some health care professionals, non-specialist in HIV/AIDS, had a negative impact on future experiences in other health services. Besides the effects of institutional stigma, the perception of women was that the service did not include dedicated space for the expression of other needs beyond the disease, which could help in fighting the infection. CONCLUSIONS Living with HIV was strongly linked to stigma. The results show the importance of strengthening educational approaches and emotional support at the time of diagnosis in order to facilitate coping with the condition of seropositivity.

    Objective To determine whether rapidly cleared episodes of herpes simplex virus (HSV) reactivation occur in HIV-infected adults. Methods Twenty HSV-2 seropositive, HIV seropositive adults, including 9 (45%) who were also HSV-1 seropositive, collected oral and anogenital swabs for HSV DNA PCR 4 times a day for 60 days. Samples were positive for HSV if we detected ≥ 150 copies of HSV DNA/mL of specimen. Results Median HSV shedding episode duration was 7.5 (range 4–253) hours for oral and 11 (range 4–328) hours for anogenital reactivation. Thirty-five percent of oral and 29% of anogenital reactivations lasted ≤ 6 hours, and 59% of oral and 53% of anogenital reactivations lasted ≤ 12 hours. Seven of 9 participants who shed orally and 10 of 15 who shed anogenitally had ≥ 1 reactivation lasting ≤ 6 hours. The median maximum level of HSV DNA detected in an episode increased with episode duration for both oral and anogenital episodes. Concurrent oral and anogenital shedding occurred more frequently than expected: Oral HSV shedding was detected on 17% of time points with anogenital, but 1% of time points without anogenital, shedding (p < 0.001). Conclusions Rapidly cleared episodes of oral and anogenital HSV shedding occur in HIV-infected persons, supporting the hypothesis that frequent anogenital mucosal immune activation caused by HSV-2 is present in HIV co-infected persons, potentially contributing to HIV infectiousness.

    In persons with advanced immunosuppression, Mycobacterium avium complex (MAC) typically causes disseminated disease with systemic symptoms. We report 2 cases in which MAC caused localized osteomyelitis in human immunodeficiency virus (HIV)-infected individuals on antiretroviral therapy with rising CD4 counts. We summarize 17 additional cases of HIV-associated MAC osteomyelitis from the literature and compare CD4 count at presentation for vertebral cases versus nonvertebral cases, which reveals a significantly higher CD4 at presentation for vertebral cases (median 251 cells/µL vs 50 cells/µL; P = .043; Mann–Whitney U test). The literature review demonstrates that the majority of cases of MAC osteomyelitis, especially vertebral, occurs in individuals with CD4 counts that have increased to above 100 cells/µL on antiretroviral therapy. Among HIV-infected individuals with osteomyelitis, MAC should be considered a possible etiology, particularly in the setting of immune reconstitution. PMID:26180837

    Outbreaks of sexually transmitted hepatitis C virus (HCV) infections have been recently reported in HIV-infected men who have sex with men (MSM) in Europe, Australia, and North America. Little is known concerning whether this also occurs in other Asia-Pacific countries. Between 1994 and 2010, a prospective observational cohort study was performed to assess the incidence of recent HCV seroconversion in 892 HIV-infected patients (731 MSM and 161 heterosexuals) who were not injecting drug users. A nested case-control study was conducted to identify associated factors with recent HCV seroconversion, and phylogenetic analysis was performed using NS5B sequences amplified from seroconverters. During a total followup duration of 4,270 person-years (PY), 30 patients (3.36%) had HCV seroconversion, with an overall incidence rate of 7.03 per 1,000 PY. The rate increased from 0 in 1994 to 2000 and 2.29 in 2001 to 2005 to 10.13 per 1,000 PY in 2006 to 2010 (P < 0.05). After adjustment for age and HIV transmission route, recent syphilis remained an independent factor associated with HCV seroconversion (odds ratio, 7.731; 95% confidence interval, 3.131 to 19.086; P < 0.01). In a nested case-control study, seroconverters had higher aminotranferase levels and were more likely to have CD4 ≥ 200 cells/μl and recent syphilis than nonseroconverters (P < 0.05). Among the 21 patients with HCV viremia, phylogenetic analysis revealed 7 HCV transmission clusters or pairs (4 within genotype 1b, 2 within genotype 2a, and 1 within genotype 3a). The incidence of HCV seroconversion that is associated with recent syphilis is increasing among HIV-infected patients in Taiwan. PMID:22189113

    Background More than half of persons living with HIV (PLWH) in the US smoke cigarettes, and tobacco use is responsible for considerable morbidity and mortality in this group. Little is known about the efficacy of tobacco treatment strategies in PLWH. Design Randomized controlled trial comparing Positively Smoke Free (PSF), an intensive group therapy intervention targeting HIV-infected smokers, to standard care. Methods A cohort of 145 PLWH smokers, recruited from an HIV-care center in the Bronx, New York, were randomized 1:1 into the PSF program or standard care. All were offered a 3-month supply of nicotine replacement therapy. PSF is an eight session program tailored to address the needs and concerns of HIV-infected smokers. Sessions were co-facilitated by a graduate student and an HIV-infected peer. The primary outcome was biochemically-confirmed, seven-day point-prevalence abstinence at three months. Results In the intention to treat analysis, PSF condition subjects had nearly double the quit rate of controls (19.2% vs 9.7%, P=0.11). In the complete case, as-treated analysis, assignment to PSF was associated with increased odds of quitting (ORadj 3.55, 95% CI: 1.04– 12.0). Latino ethnicity and lower loneliness score were predictive of abstinence. Subjects in the PSF condition exhibited significant decreases in daily cigarette consumption and significant increases in self-efficacy and in motivation to quit. Attendance of ≥7 sessions was associated with higher quit rates. Conclusions These findings suggest a positive effect of PSF on cessation rates in PLWH smokers. Loneliness and self-efficacy are influential factors in the smoking behaviors of PLWH. PMID:22732470

    Synopsis Most HIV infections among women occur early in reproductive life, which highlights the importance of understanding the impact of HIV on reproductive functions, and also the potential implications of reproductive function and aging on the course of HIV disease. HIV infection may influence reproductive biology via multiple mechanisms including: potential directs effects on HIV on the hypothalamic-pituitary-gonadal axes, implications of HIV-related immune dysfunction on reproductive biology, effects of antiretroviral treatments on reproductive functions and the impact of treatment related immune reconstitution on reproductive health. Ovarian function is a crucial component of reproductive biology in women, but standard assessment methods are of limited applicability to women with some chronic diseases, such as HIV. New antiretroviral treatments have the potential to increase the ease of conception planning, and to improve fertility. Drug-drug interactions between antiretroviral medications and hormonal contraceptives are potentially significant and merit careful provider attention. While HIV infection is not a major cause of infertility, high level viremia and low CD4 lymphocyte counts are associated with reduced fertility rates. Conception and pregnancy can now be achieved without transmission of HIV to sexual partner or new born, but complications of pregnancy may be more common in HIV infected women than uninfected women.

    The long-term impact on bone health of lifelong HIV infection and prolonged ART in growing and developing children is not yet known. Measures of bone health in youth must be interpreted in the context of expected developmental and physiologic changes in bone mass, size, density and strength that occur from fetal through adult life. Low bone mineral density (BMD) appears to be common in perinatally HIV-infected youth, especially outside of high-income settings, but data are limited and interpretation complicated by the need for better pediatric norms. The potential negative effects of tenofovir on BMD and bone mass accrual are of particular concern as this drug may be used more widely in younger children. Emphasizing good nutrition, calcium and vitamin D sufficiency, weight-bearing exercise and avoidance of alcohol and smoking are effective and available approaches to maintain and improve bone health in all settings. More data are needed to inform therapies and monitoring for HIV-infected youth with proven bone fragility. While very limited data suggest lack of marked increase in fracture risk for youth with perinatal HIV infection, the looming concern for these children is that they may fail to attain their expected peak bone mass in early adulthood which could increase their risk for fractures and osteoporosis later in adulthood.

    The aim of the paper is to analyse the prevalence of liver involvement and related factors in HIV-infected patients with early syphilis (<2 years). Liver involvement was defined as an elevation above normal ranges of alanine transaminase, aspartate aminotransferase, gamma-glutamyltransferase and/or alkaline phosphatase during early syphilis, or doubling of previous levels in patients with liver enzyme elevation before syphilis. We undertook a multicentre study and of the 147 cases, 86.4% were men who had sex with men, and the diagnoses of syphilis and HIV infection were coincident in 48 (32.7%). Liver involvement was detected in 45 (30.6%) and the only related factor was a rapid plasma reagin (RPR) titre ≥1/64 (odds ratio 3.76; 95% confidence interval 1.3-10.5; P = 0.012). In conclusion, liver involvement occurs in around one-third of HIV-infected patients with early syphilis and is associated with high RPR levels. Syphilis should be included in the differential diagnosis of liver enzyme elevation in HIV-infected patients. PMID:23467288

    Oral mucosal cells can be infected by exogenous HIV during receptive oral sex or breast-feeding. The risk of oral mucosal infection depends on the infection efficiency of the HIV strains present in the oral cavity, the viral titers, and the defense mechanisms in the oral cavity environment. It is expected that alcohol can weaken the host defense mechanism against HIV infection in the oral cavity. We modified an HIV strain, NL4-3, by inserting the enhanced green fluorescent protein gene and used this virus to infect oral epithelial cells obtained from patients. Various concentrations of ethanol (0%-4%) were added to the infected cells. HIV-infected cells were detected by fluorescent microscopy or fluorescence-activated cell sorting. We found that ethanol significantly increases HIV infection of primary oral epithelial cells (POEs). POEs pretreated with 4% ethanol for less than 10 minutes demonstrated 3- to 6-fold higher susceptibility to infection by the CXCR-4 HIV strain NL4-3. Our studies also demonstrated that HIV infects POEs through a gp120-independent mechanism. We tested an HIV CCR5 strain, JRCSF, and also found its infection efficiency to be stimulated by alcohol. Our results indicate that in cell culture conditions, the ranges of concentrations of alcohol that are commercially available are able to stimulate the infection efficiency of HIV in POEs.

    A survey conducted in the US, Canada, India, and Thailand found that substantial numbers of health personnel were unaware both of problems associated with the enzyme-linked immunosorbent assay (ELISA) serologic test and of the asymptomatic stage of human immunodeficiency virus (HIV) infection. The proportion of surveyed physicians who had treated an HIV-infected patient ranged from a low of 30% in India to a high of 98% in the US. Mean HIV/acquired immunodeficiency syndrome (AIDS) knowledge scores were 83% in India, 84% in Thailand, 92% in Canada, and 93% in the US. Only 67% of health care providers from India understood the concept of false-negative ELISA test results, and only 78% of Canadian and 76% of US respondents understood the meaning of a false-positive result. Awareness of asymptomatic HIV infection ranged from 32% in India to 74% in Canada. The level of comfort in caring for AIDS patients and AIDS knowledge scores were directly correlated with the amount of previous contact with HIV-infected patients. India and Thailand have been identified by the World Health Organization as the countries likely to experience the sharpest increases in HIV in the years ahead. AIDS prevention efforts in these countries have been hindered by religious and cultural proscriptions against public discussions of sexuality, mistaken idea that AIDS is a foreigners' disease, inadequate funding, and concerns about adverse effects on the tourist industry.

    According to a survey from the HIV Cost and Services Utilization Study (HCSUS), approximately 53% of HIV-infected patients reported drinking alcohol and 8% were classified as heavy drinkers. The role of alcohol as a risk factor for HIV infection has been widely studied and recent research has found a significant association between heavy alcohol consumption and lower levels of CD4 T cells among HIV-infected alcoholics. Although there is evidence on the role of alcohol as a risk factor for HIV transmission and disease progression, there is a need for population studies to determine the genetic mechanisms that affect alcohol's role in HIV disease progression. One of the mechanisms of interest is the dopaminergic system. To date, the effects of dopamine on HIV neuroimmune pathogenesis are not well understood; however, dopaminergic neural degeneration due to HIV is known to occur by viral invasion into the brain via immune cells, and modulation of dopamine in the CNS may be a common mechanism by which different types of substances of abuse impact HIV disease progression. Although previous studies have shown an association of D(2) dopamine receptor (DRD2) polymorphisms with severity of alcohol dependence, the expression of this allele risk on HIV patients with alcohol dependence has not been systematically explored. In the current study, DRD2 Taq1A and C957T SNP genotyping analyses were performed in 165 HIV-infected alcohol abusers and the results were examined with immune status and CD4 counts. PMID:25053368

    Marburg virus, the Kaposi's sarcoma-associated herpesvirus (KSHV) and Dengue virus all activate, and benefit from, expression of the transcription regulator nuclear erythroid 2-related factor 2 (Nrf2). The impact of Nrf2 activation on human immunodeficiency virus (HIV) infection has not been tested. Sulforaphane (SFN), produced in cruciferous vegetables after mechanical damage, mobilizes Nrf2 to potently reprogram cellular gene expression. Here we show for the first time that SFN blocks HIV infection in primary macrophages but not in primary T cells. Similarly SFN blocks infection in PMA-differentiated promonocytic cell lines, but not in other cell lines tested. siRNA-mediated depletion of Nrf2 boosted HIV infectivity in primary macrophages and reduced the anti-viral effects of SFN treatment. This supports a model in which anti-viral activity is mediated through Nrf2 after it is mobilized by SFN. We further found that, like the type I interferon-induced cellular anti-viral proteins SAMHD1 and MX2, SFN treatment blocks infection after entry, but before formation of 2-LTR circles. Interestingly however, neither SAMHD1 nor MX2 were upregulated. This shows for the first time that Nrf2 action can potently block HIV infection and highlights a novel way to trigger this inhibition.

    The great success in the prevention and treatment of pediatric HIV in high resource countries, and now in low resource countries, has changed the face of the HIV epidemic in children from one of near certain mortality to that of a chronic disease. However, these successes pose new challenges as perinatally HIV-infected youth survive into adulthood. Increased survival of HIV-infected children is associated with challenges in maintaining adherence to what is likely life-long therapy, and in selecting successive antiretroviral drug regimens, given the limited availability of pediatric formulations, limitations in pharmacokinetic and safety data of drugs in children, and the development of extensive drug resistance in multi-drug-experienced children. Pediatric HIV care must now focus on morbidity related to long-term HIV infection and its treatment. Survival into adulthood of perinatally HIV-infected youth in high resource countries provides important lessons about how the epidemic will change with increasing access to antiretroviral therapy for children in low resource countries. This series of papers will focus on issues related to management of perinatally infected youth and young adults. PMID:23782484

    Thailand, a popular tourist destination for Norwegians, is experiencing an increasing epidemic of HIV infection. We used the Norwegian surveillance system for communicable diseases to assess the connections between the Norwegian and Thai epidemics. Before 1999, 1,869 cases of HIV-infection had been reported in Norway. From 1993 to 1998, 1,334 cases of gonorrhoea and 62 cases of syphilis were reported. We studied cases with a Thai patient or source partner and cases acquired in Thailand. 56 (3%) of HIV-infection cases, 64 (5%) of gonorrhoea cases and two (3%) of syphilis cases were connected to Thailand. All the Norwegians who acquired HIV in Thailand were males, with a median age of 39. Eight of them were diagnosed in 1998 as compared to 16 during the previous ten-year period. 21 Thai women and seven males were diagnosed with HIV infection in Norway, eight in 1998 and 20 in the previous ten-year period. The Norwegian HIV epidemic is influenced by the Thai epidemic. Norwegian men are infected in Thailand during holidays. Thai women come with their Norwegian partner to Norway and later discover their HIV status. We recommend raising the awareness of the Thai epidemic among Norwegian tourists. Immigrants to Norway from highly endemic countries should be offered HIV counselling and testing. PMID:10592752

    Background Geriatric syndromes such as falls, frailty, and functional impairment are multifactorial conditions used to identify vulnerable older adults. Limited data exists on these conditions in older HIV-infected adults and no studies have comprehensively examined these conditions. Methods Geriatric syndromes including falls, urinary incontinence, functional impairment, frailty, sensory impairment, depression and cognitive impairment were measured in a cross-sectional study of HIV-infected adults age 50 and older who had an undetectable viral load on antiretroviral therapy (ART). We examined both HIV and non-HIV related predictors of geriatric syndromes including sociodemographics, number of co-morbidities and non-antiretroviral medications, and HIV specific variables in multivariate analyses. Results We studied 155 participants with a median age of 57 (IQR 54-62); (94%) were men. Pre-frailty (56%), difficulty with instrumental activities of daily living (46%), and cognitive impairment (47%) were the most frequent geriatric syndromes. Lower CD4 nadir (IRR 1.16, 95% CI 1.06-1.26), non-white race (IRR 1.38, 95% CI 1.10-1.74), and increasing number of comorbidities (IRR 1.09, 95%CI 1.03-1.15) were associated with increased risk of having more geriatric syndromes. Conclusions Geriatric syndromes are common in older HIV infected adults. Treatment of comorbidities and early initiation of ART may help to prevent development of these age related complications. Clinical care of older HIV-infected adults should consider incorporation of geriatric principles. PMID:26009828

    Marburg virus, the Kaposi's sarcoma-associated herpesvirus (KSHV) and Dengue virus all activate, and benefit from, expression of the transcription regulator nuclear erythroid 2-related factor 2 (Nrf2). The impact of Nrf2 activation on human immunodeficiency virus (HIV) infection has not been tested. Sulforaphane (SFN), produced in cruciferous vegetables after mechanical damage, mobilizes Nrf2 to potently reprogram cellular gene expression. Here we show for the first time that SFN blocks HIV infection in primary macrophages but not in primary T cells. Similarly SFN blocks infection in PMA-differentiated promonocytic cell lines, but not in other cell lines tested. siRNA-mediated depletion of Nrf2 boosted HIV infectivity in primary macrophages and reduced the anti-viral effects of SFN treatment. This supports a model in which anti-viral activity is mediated through Nrf2 after it is mobilized by SFN. We further found that, like the type I interferon-induced cellular anti-viral proteins SAMHD1 and MX2, SFN treatment blocks infection after entry, but before formation of 2-LTR circles. Interestingly however, neither SAMHD1 nor MX2 were upregulated. This shows for the first time that Nrf2 action can potently block HIV infection and highlights a novel way to trigger this inhibition.

    Myeloid and plasmacytoid dendritic cells (DCs) are important mediators of both innate and adaptive immunity against pathogens such as HIV. During the course of HIV infection, blood DC numbers fall substantially. In the present study, we sought to determine how early in HIV infection the reduction occurs and whether the remaining DC subsets maintain functional capacity. We find that both myeloid DC and plasmacytoid DC levels decline very early during acute HIV in-fection. Despite the initial reduction in numbers, those DCs that remain in circulation retain their function and are able to stimulate allogeneic T-cell responses, and up-regulate maturation markers plus produce cytokines/chemokines in response to stimulation with TLR7/8 agonists. Notably, DCs from HIV-infected subjects produced significantly higher levels of cytokines/chemokines in response to stimulation with TLR7/8 agonists than DCs from uninfected controls. Further examination of gene expression profiles indicated in vivo activation, either directly or indirectly, of DCs during HIV infection. Taken together, our data demonstrate that despite the reduction in circulating DC numbers, those that remain in the blood display hyperfunctionality and implicates a possible role for DCs in promoting chronic immune activation.

    Antibody affinity maturation by somatic hypermutation of B-cell immunoglobulin variable region genes has been studied for decades in various model systems using well-defined antigens. While much is known about the molecular details of the process, our understanding of the selective forces that generate affinity maturation are less well developed, particularly in the case of a co-evolving pathogen such as HIV. Despite this gap in understanding, high-throughput antibody sequence data are increasingly being collected to investigate the evolutionary trajectories of antibody lineages in HIV-infected individuals. Here, we review what is known in controlled experimental systems about the mechanisms underlying antibody selection and compare this to the observed temporal patterns of antibody evolution in HIV infection. In addition, we describe how our current understanding of antibody selection mechanisms leaves questions about antibody dynamics in HIV infection unanswered. Without a mechanistic understanding of antibody selection in the context of a co-evolving viral population, modelling and analysis of antibody sequences in HIV-infected individuals will be limited in their interpretation and predictive ability.

    Human papillomavirus (HPV) causes the majority of oropharyngeal cancers in the United States, yet the risk factors for and natural history of oral HPV infection are largely unknown. In 2010-2011, a US-based longitudinal cohort study of 761 human immunodeficiency virus (HIV)-infected and 469 at-risk HIV-uninfected participants from the Multicenter AIDS Cohort Study and the Women's Interagency HIV Study was initiated. Semiannually collected oral rinses were evaluated for 37 HPV genotypes using the Roche LINEAR ARRAY HPV Genotyping Test (Roche Molecular Systems, Pleasanton, California), and factors associated with oral HPV incidence and clearance were explored using adjusted Wei-Lin-Weissfeld modeling. Through 2013, the 2-year cumulative incidence of any type of oral HPV infection was 34% in HIV-infected persons and 19% in HIV-uninfected persons. However, many of these infections cleared. Seven percent of incident infections and 35% of prevalent infections persisted for at least 2 years. After adjustment for other risk factors, HIV infection (adjusted hazard ratio = 2.3, 95% confidence interval: 1.7, 3.2), reduced current CD4 cell count, and increased numbers of oral sex and "rimming" partners increased the risk of incident oral HPV infection, whereas male sex, older age, and current smoking increased the risk of oral HPV persistence (each P < 0.05). This helps explain the consistent associations observed between these factors and prevalent oral HPV infection in previous cross-sectional studies. PMID:25480823

    Given the inordinate burden of HIV illness borne by African American men, investigations of HIV prevention and care in this population are urgently needed. In this qualitative study, a sample of 20 HIV-infected African American men participated in two focus groups in which they exchanged experiences and ideas about living with HIV. They shared details about how they were personally impacted by HIV, and together they constructed a perspective on the larger societal context in which the HIV infection rate among African American men continues unabated. The men focused on growing complacency about HIV/AIDS in the United States, underfunding of supports and services, stigmas operative in African American communities, and differential care based on race, gender, and diagnosis. They saw opportunity in personal strategies that help individual men infected with HIV to take a more empowered stance to deal with the disease and improve their health but looked for changes undertaken by African Americans at the community level to make a real difference in the epidemic. Their vision included enhanced support for HIV prevention and care from influential community institutions like Black churches, more open dialogue about drugs and sexual behavior, and capacity-building for families whose members are HIV-infected or at risk for HIV.

    A random sample of 270 general practitioners in London was interviewed to assess current practice and opinions about managing psychological and social problems related to HIV infection. Physicians caring for patients with HIV infection were asked about numbers of patients in their pratice with HIV or AIDS; consultation with third parties such as sexual partners or family; reports to employers and other third parties; terminal care; contact with HIV clinics; testing for HIV infection without consent; and the impact of patients with HIV infection on their practice. All physicians were asked about patients concerned with HIV infection; awareness of other health resources for patients with HIV infection; terminal care; "safer sex" education; confidentiality; interest in AIDS; intravenous drug users as patients; managing homosexual patients; and ethical considerations. King discusses the findings and draws conclusions about primary care of HIV-infected patients in London. PMID:2508884

    Participants were recruited from a sexually transmitted disease (STD) clinic in Florida and were assessed regarding the knowledge and awareness of non-AIDS conditions associated with HIV infection. Questionnaires were administered before and after a brief information session on non-AIDS conditions associated with HIV infection. Participants included men (n = 46) and women (n = 51). Prior to the information session, at baseline, only 34% of the participants were worried about HIV infection. Most participants (82%) agreed that HIV could be treated with antiretroviral therapy (ART), while only 38% were aware that HIV-associated conditions cannot be easily treated with ART. After the information session, almost all participants reported they were concerned regarding the risk of HIV infection. High-risk patients may have limited knowledge about the consequences of HIV infection beyond the traditional AIDS-associated conditions. Increased awareness of these less known consequences of HIV infection may decrease the potential for complacency regarding acquiring HIV infection. PMID:25331221

    Drug addicts have, in general, a less complicated course of HIV infection than homosexual HIV patients. They show fewer opportunistic infections and tumors. But this advantage is lost by unnecessary complications due to their psychic disorders. Their non-compliance and concealment of signs of disease lead to worse outcomes of infections, which could be well-treated or prevented. PMID:8300042

  16. Randomized, Controlled Intervention Trial of Male Circumcision for Reduction of HIV Infection Risk: The ANRS 1265 Trial

    2005-01-01

    Background Observational studies suggest that male circumcision may provide protection against HIV-1 infection. A randomized, controlled intervention trial was conducted in a general population of South Africa to test this hypothesis. Methods and Findings A total of 3,274 uncircumcised men, aged 18–24 y, were randomized to a control or an intervention group with follow-up visits at months 3, 12, and 21. Male circumcision was offered to the intervention group immediately after randomization and to the control group at the end of the follow-up. The grouped censored data were analyzed in intention-to-treat, univariate and multivariate, analyses, using piecewise exponential, proportional hazards models. Rate ratios (RR) of HIV incidence were determined with 95% CI. Protection against HIV infection was calculated as 1 − RR. The trial was stopped at the interim analysis, and the mean (interquartile range) follow-up was 18.1 mo (13.0–21.0) when the data were analyzed. There were 20 HIV infections (incidence rate = 0.85 per 100 person-years) in the intervention group and 49 (2.1 per 100 person-years) in the control group, corresponding to an RR of 0.40 (95% CI: 0.24%–0.68%; p < 0.001). This RR corresponds to a protection of 60% (95% CI: 32%–76%). When controlling for behavioural factors, including sexual behaviour that increased slightly in the intervention group, condom use, and health-seeking behaviour, the protection was of 61% (95% CI: 34%–77%). Conclusion Male circumcision provides a degree of protection against acquiring HIV infection, equivalent to what a vaccine of high efficacy would have achieved. Male circumcision may provide an important way of reducing the spread of HIV infection in sub-Saharan Africa.

    BACKGROUND: Young gay and bisexual men may perceive that the consequences of HIV infection have dramatically improved with the availability of highly active antiretroviral therapy. We therefore sought to identify trends in HIV infection rates and associated risk behaviours among young gay and bisexual men in Vancouver. METHODS: Prospective cohort study involving gay and bisexual men aged 18-30 years who had not previously tested HIV positive. Subjects were recruited through physicians, clinics and community outreach in Vancouver. Annually participants were tested for HIV antibodies and asked to complete a self-administered questionnaire pertaining to sociodemographic characteristics, sexual behaviours and substance use. Prevalence of HIV infection and risk behaviours were determined for eligible participants who completed a baseline questionnaire and HIV testing as of May 1998. The primary outcome was the proportion of men who reported having protected sex during the year before enrollment and who reported any episode of unprotected sex by the time of the first follow-up visit. RESULTS: A total of 681 men completed a baseline questionnaire and HIV testing as of May 1998. The median duration between baseline and the first follow-up visit was 14 months. The median age was 25 years. Most of the subjects were white and of high socioeconomic status. The majority (549 [80.6%]) reported having sex only with men; 81 (11.9%) reported bisexual activity. Of the 503 men who had one or more regular male partners, 245 (48.7%) reported at least one episode of unprotected anal sex in the year before enrollment; the corresponding number among the 537 who had one or more casual male partners was 140 (26.1%). The prevalence and incidence of HIV seropositivity were 1.8% (95% confidence interval [CI] 0.8%-2.8%) and 1.7 per 100 person-years [95% CI 0.7-2.7], respectively. Fifty-two (26.5%) of the 196 and 55 (29.7%) of the 185 men with regular partners who reported having practiced

    Background Disclosure of the diagnosis of HIV to HIV-infected children is challenging for caregivers. Despite current recommendations, data suggest that levels of disclosure of HIV status to HIV-infected children receiving care in resource-limited settings are very low. Few studies describe the disclosure process for children in these settings, particularly the motivators, antecedent goals, and immediate outcomes of disclosure to HIV-infected children. This study examined caregivers' perception of the disclosure concept prior to disclosure, their motivation towards or away from disclosure, and their short- and long-term intentions for disclosure to their HIV-infected children. Methods In-depth interviews were conducted with primary caregivers of 40 HIV-infected children (ages 5–15 years) who were receiving HIV care but did not know their HIV status. Results Caregivers of HIV-infected children mainly perceived disclosure as a single event rather than a process of gradual delivery of information about the child's illness. They viewed disclosure as potentially beneficial both to children and themselves, as well as an opportunity to explain the parents' role in the transmission of HIV to the children. Caregivers desired to personally conduct the disclosure; however, most reported being over-whelmed with fear of negative outcomes and revealed a lack of self-efficacy towards managing the disclosure process. Consequently, most cope by deception to avoid or delay disclosure until they perceive their own readiness to disclose. Conclusions Interventions for HIV disclosure should consider that caregivers may desire to be directly responsible for disclosure to children under their care. They, however, need to be empowered with practical skills to recognize opportunities to initiate the disclosure process early, as well as supported to manage it in a phased, developmentally appropriate manner. The potential role for peer counselors in the disclosure process deserves further

    Abstract Our objective was to compare obesity prevalence among human immunodeficiency virus (HIV)-infected adults receiving care and the U.S. general population and identify obesity correlates among HIV-infected men and women. Cross-sectional data was collected in 2009 to 2010 from 2 nationally representative surveys: Medical Monitoring Project (MMP) and National Health and Nutrition Examination Survey (NHANES). Weighted prevalence estimates of obesity, defined as body mass index ≥30.0 kg/m2, were compared using prevalence ratios (PR, 95% confidence interval [CI]). Correlates of obesity in HIV-infected adults were examined using multivariable logistic regression. Demographic characteristics of the 4006 HIV-infected adults in MMP differed from the 5657 adults from the general U.S. population in NHANES, including more men (73.2% in MMP versus 49.4% in NHANES, respectively), black or African Americans (41.5% versus 11.6%), persons with annual incomes <$20,000 (64.5% versus 21.9%), and homosexuals or bisexuals (50.9% versus 3.9%). HIV-infected men were less likely to be obese (PR 0.5, CI 0.5–0.6) and HIV-infected women were more likely to be obese (PR1.2, CI 1.1–1.3) compared with men and women in the general population, respectively. Among HIV-infected women, younger age was associated with obesity (<40 versus >60 years). Among HIV-infected men, correlates of obesity included black or African American race/ethnicity, annual income >$20,000 and <$50,000, heterosexual orientation, and geometric mean CD4+ T-lymphocyte cell count >200 cells/μL. Obesity is common, affecting 2 in 5 HIV-infected women and 1 in 5 HIV-infected men. Correlates of obesity differ for HIV-infected men and women; therefore, different strategies may be needed for the prevention and treatment. PMID:26166086

    Hispanic and African American adolescents are more likely than white Anglo youth to harbor misconceptions about acquired immunodeficiency syndrome (AIDS) and are also more likely to engage in intravenous drug use and sexual intercourse. This paper describes the development of an AIDS prevention curriculum that uses an interactive videodisc program to teach skills for interventions. Focus group and expert panel studies yielded suggests for intervention vignettes and scenes relevant to Hispanic and African American adolescents. The authors then developed and produced a sample curriculum, specifically designed for Hispanic youth. Content was designed to build knowledge, attitudes, and skills in handling situations where young persons are at risk for human immunodeficiency virus (HIV) infection. The feasibility of the finished pilot product was tested with adolescents and with professionals who serve ethnic and racial minority youth. Adults and Hispanic adolescent viewers rated the videodisc as enjoyable, interesting, and likely to achieve positive effects with the intended target population. Findings suggest that the interactive videodisc is a useful way to interest and help Hispanic adolescents learn ways of reducing their risk of contracting and spreading HIV infection through lifestyle practices. This developmental research in the use of interactive videodisc also provides a basis for further investigation. PMID:1375760

    A majority of inmates in the state of Connecticut Department of Corrections use opioids or are opioid dependent before incarceration. None of the state's prisons offer opioid substitution therapy other than for detoxification or maintenance therapy for women during pregnancy. On release to the community, most prisoners relapse to drug use and this has been associated with higher recidivism rates, and less adherence to antiretroviral medications for HIV-infected persons. Nationally and internationally, methadone (METH) and buprenorphine (BUP) have been found to decrease relapse to drug use, decrease recidivism rates, improve adherence to antiretroviral medications, decrease HIV-risk taking behaviors, and improve mortality. However, the general knowledge about opioid substitution therapy among correctionalfacility staff has been reported as substandard. This pilot study compiled results of answers to anonymous surveys from 27 individuals who work directly with inmates in a patient-care capacity for the Connecticut Department of Corrections (CT DOC) and CT DOC case-management referral program (Project TLC) in the year 2006. The surveys included questions regarding current attitudes and knowledge about opioid substitution therapy for prisoners. A minority of respondents refer released prisoners with a history of opioid dependency to METH or BUP treatment. The majority of correctional workers and case-management referral workers did not have knowledge about BUP or METH's ability to improve health and decrease HIV risk taking behaviors. This study found that more education of individuals treating and caring for HIV-infected opioid dependent prisoners is needed. PMID:18557164

    The introduction of potent combination antiretroviral therapy (cART) has had a remarkable impact on the natural history of HIV infection, leading to a dramatic decline in the mortality rate and a considerable increase in the life expectancy of HIV-positive people. However, cART use is frequently associated with several metabolic complications, mostly represented by lipid metabolism alterations, which are reported very frequently among persons treated with antiretroviral agents. In particular, hyperlipidaemia occurs in up to 70%-80% of HIV-positive subjects receiving cART and is mainly associated with specific antiretroviral drugs belonging to three classes of antiretroviral agents: NRTIs, NNRTIs and PIs. The potential long-term consequences of cART-associated dyslipidaemia are not completely understood, but an increased risk of premature coronary heart disease has been reported in HIV-infected patients on cART, so prompt correction of lipid metabolism abnormalities is mandatory in this population. Dietary changes, regular aerobic exercise and switching to a different antiretroviral regimen associated with a more favourable metabolic profile are the first steps in clinical management, but lipid-lowering therapy with fibrates or statins is often required. In this case, the choice of hypolipidaemic drugs should take into account the potential pharmacokinetic interactions with many antiretroviral agents. PMID:26846208

    This study aimed to investigate the association between herpes zoster (HZ) and human immunodeficiency virus (HIV). Data were retrieved from the Longitudinal Health Insurance Databases (LHID 2005 and 2010), Taiwan. The International Classification of Diseases, 9th Revision, Clinical Modification [ICD-9-CM] codes were used to identify Hz from 2001–2004. Identification of HIV infection was from 2005–2010. The hazard ratios of HIV among herpes zoster infected and non-herpes zoster infected patients were estimated using multiple Cox proportional hazard model. In general, 19685 participants were identified with Hz. The HIV incidence rates (per 104 person-months) in herpes zoster infected and non-infected patients were 0.191(95% CI 0.130–0.280) and 0.079 (95% CI 0.074–0.084), respectively while the hazard ratio (HR) of HIV among infected individuals was 3.518 (95% CI 2.375–5.211). This study concludes that herpes zoster could be considered as a predictor of HIV infection especially among Asian populations, hence it is vital to test herpes zoster infected individuals for HIV antibodies.

    2016-04-01

    In the antiretroviral therapy (ART) era, serious non-AIDS events (SNAEs) have become the major causes of morbidity and mortality in HIV-infected persons. Early ART initiation has the strongest evidence for reducing SNAEs and mortality. Biomarkers of immune activation, inflammation and coagulopathy do not fully normalize despite virologic suppression and persistent immune activation is an important contributor to SNAEs. A number of strategies aimed to reduce persistent immune activation including ART intensification to reduce residual viremia; treatment of co-infections to reduce chronic antigen stimulation; the use of anti-inflammatory agents, reducing microbial translocation as well as interventions to improve immune recovery through cytokine administration and reducing lymphoid tissue fibrosis, have been investigated. To date, there is little conclusive evidence on which strategies beyond treatment of hepatitis B and C co-infections and reducing cardiovascular risk factors will result in clinical benefits in patients already on ART with viral suppression. The use of statins seems to show early promise and larger clinical trials are underway to confirm their efficacy. At this stage, clinical care of HIV-infected patients should therefore focus on early diagnosis and prompt ART initiation, treatment of active co-infections and the aggressive management of co-morbidities until further data are available.

    Background. Although the association between lipoatrophy and highly active antiretroviral therapy (HAART) is well known, other nondrug factors may be associated with lipoatrophy in people living with HIV/AIDS (PLWHA). There are no reports of lipoatrophy from Nigeria, a country with the second largest number of PLWHA. We aimed to determine the prevalence, characteristics, and factors associated with lipoatrophy in a cohort of patients attending the HIV clinic in Lagos University Teaching Hospital, Nigeria. Methods. Two hundred and eighty-eight patients with HIV infection were recruited for the study. The study protocol involved administration of a questionnaire, targeted physical examination (including anthropometric indices and skin fold thickness), and bioelectrical impedance analysis measurements. Lipoatrophy was defined clinically. Results. Lipoatrophy was present in 75 (26.0%) persons. It was associated with lower body circumferences, skin fold thicknesses, and lower % body fat with preservation of skeletal muscle mass (all P < 0.05). Male gender and HAART use were the factors associated with lipoatrophy on multivariate analysis (P < 0.05). Conclusion. Lipoatrophy is frequently encountered in patients with HIV infection in Nigeria, with HAART use conferring an added factor in its development. There is need for more physician and patient awareness of this condition. PMID:25821597

    Background Cigarette smoking is widespread among HIV-infected patients, who confront increased risk of smoking-related co-morbidities. The effects of HIV infection and HIV-related variables on smoking and smoking cessation are incompletely understood. We investigated the correlates of smoking and quitting in an HIV-infected cohort using a validated natural language processor to determine smoking status. Method We developed and validated an algorithm using natural language processing (NLP) to ascertain smoking status from electronic health record data. The algorithm was applied to records for a cohort of 3487 HIV-infected from a large health care system in Boston, USA, and 9446 uninfected control patients matched 3:1 on age, gender, race and clinical encounters. NLP was used to identify and classify smoking-related portions of free-text notes. These classifications were combined into patient-year smoking status and used to classify patients as ever versus never smokers and current smokers versus non-smokers. Generalized linear models were used to assess associations of HIV with 3 outcomes, ever smoking, current smoking, and current smoking in analyses limited to ever smokers (persistent smoking), while adjusting for demographics, cardiovascular risk factors, and psychiatric illness. Analyses were repeated within the HIV cohort, with the addition of CD4 cell count and HIV viral load to assess associations of these HIV-related factors with the smoking outcomes. Results Using the natural language processing algorithm to assign annual smoking status yielded sensitivity of 92.4, specificity of 86.2, and AUC of 0.89 (95% confidence interval [CI] 0.88–0.91). Ever and current smoking were more common in HIV-infected patients than controls (54% vs. 44% and 42% vs. 30%, respectively, both P<0.001). In multivariate models HIV was independently associated with ever smoking (adjusted rate ratio [ARR] 1.18, 95% CI 1.13–1.24, P <0.001), current smoking (ARR 1.33, 95% CI 1.25

    The reasons for persistent brain dysfunction in chronically HIV-infected persons on stable combined antiretroviral therapies (CART) remain unclear. Host and viral factors along with their interactions were examined in 260 HIV-infected subjects who underwent magnetic resonance spectroscopy (MRS). Metabolite concentrations (NAA/Cr, Cho/Cr, MI/Cr, and Glx/Cr) were measured in the basal ganglia, the frontal white matter, and gray matter, and the best predictive models were selected using a bootstrap-enhanced Akaike information criterion (AIC). Depending on the metabolite and brain region, age, race, HIV RNA concentration, ADC stage, duration of HIV infection, nadir CD4, and/or their interactions were predictive of metabolite concentrations, particularly the basal ganglia NAA/Cr and the mid-frontal NAA/Cr and Glx/Cr, whereas current CD4 and the CPE index rarely or did not predict these changes. These results show for the first time that host and viral factors related to both current and past HIV status contribute to persisting cerebral metabolite abnormalities and provide a framework for further understanding neurological injury in the setting of chronic and stable disease.

    An algorithm was developed that identifies patients with new diagnoses of HIV infection by the use of electronic health records. It was based on the sequence of HIV diagnostic tests, entry of ICD-9-CM diagnostic codes, and measurement of HIV-1 plasma RNA levels in persons undergoing HIV testing from 2006 to 2012 at four large urban Veterans Health Administration (VHA) facilities. Source data were obtained from the VHA National Corporate Data Warehouse. Chart review was done by a single trained abstractor to validate site-level data regarding new diagnoses. We identified 1,153 patients as having a positive HIV diagnostic test within the VHA. Of these, 57% were determined to have prior knowledge of their HIV status from testing at non-VHA facilities. An algorithm based on the sequence and results of available laboratory tests and ICD-9-CM entries identified new HIV diagnoses with a sensitivity of 83%, specificity of 86%, positive predictive value of 85%, and negative predictive value of 90%. There were no meaningful demographic or clinical differences between newly diagnosed patients who were correctly or incorrectly classified by the algorithm. We have validated a method to identify cases of new diagnosis of HIV infection in large administrative datasets. This method, which has a sensitivity of 83%, specificity of 86%, positive predictive value of 85%, and negative predictive value of 90% can be used in analyses of the epidemiology of newly diagnosed HIV infection.

    Given the prolonged survival of HIV-infected individuals as a result of widespread availability of treatment, health-related quality of life (HRQOL) becomes a relevant endpoint for assessing the impacts of HIV interventions. We examined the reliability and validity of the World Health Organization Quality of Life in HIV-infected Persons instrument (WHOQOL-HIV-BREF) using data from 329 HIV-infected Thai patients who received outpatient care at seven public hospitals. Our findings revealed acceptable reliability, construct validity, and convergent validity of the WHOQOL-HIV-BREF. No significant difference in HRQOL was found between groups with different CD4+ T cell counts. Conversely, the subgroup with a history of opportunistic infection appeared to have a higher HRQOL compared to those in the latency stage. Challenges to the interpretation of the questions related to culture are discussed. In conclusion, the WHOQOL-HIV-BREF can be added to the limited list of instruments for comprehensive outcome evaluation of HIV interventions in Thailand. PMID:27220328

    Infections with mycobacteria, including Mycobacterium tuberculosis (Mtb) and Mycobacterium bovis (M. bovis) BCG, are a leading cause of morbidity and mortality for HIV-infected persons. In contrast to HIV, nonpathogenic SIV infections of sooty mangabeys are characterized by a lack of clinical disease including an absence of opportunistic infections. The goal of this study was to identify innate immune responses to M. bovis BCG maintained during nonpathogenic lentiviral infections through a comparison of functional responses during pathogenic HIV or nonpathogenic SIV infections. Monocytes were evaluated for their ability to express key anti-mycobacterial cytokines TNF-α and IL-12 following a six-hour ex vivo BCG exposure. While HIV-infection was associated with a decreased percentage of IL-12-producing monocytes, nonpathogenic SIV-infection was associated with an increased percentage of monocytes producing both cytokines. Gene expression analysis of PBMC following ex vivo BCG exposure identified differential expression of NK cell-related genes and several cytokines, including IFN-γ and IL-23, between HIV-infected and control subjects. In contrast, SIV-infected and uninfected-control mangabeys exhibited no significant differences in gene expression after BCG exposure. Finally, differential gene expression patterns were identified between species, with mangabeys exhibiting lower IL-6 and higher IL-17 in response to BCG when compared to humans. Overall, this comparison of immune responses to M. bovis BCG identified unique immune signatures (involving cytokines IL-12, TNF-α, IL-23, IL-17, and IL-6) that are altered during HIV, but maintained or increased during nonpathogenic SIV infections. These unique cytokine and transcriptome signatures provide insight into the differential immune responses to Mycobacteria during pathogenic HIV-infection that may be associated with an increased incidence of mycobacterial co-infections.

    Untreated human immunodeficiency virus (HIV) infection is characterized by progressive CD4(+) T-cell depletion and CD8(+) T-cell expansion, and CD4(+) T-cell depletion is linked directly to the risk for opportunistic infections and infection-associated mortality. With suppression of HIV replication by antiretroviral therapy, circulating CD4(+) Tcell numbers typically improve while CD8(+) T-cell expansion persists, and both CD4(+) T-cell cytopenia and CD8(+) T-cell expansion are associated with morbidity and mortality. In this brief review, we report on the role that selected homeostatic and inflammatory cytokines may play both in the failure of CD4(+) T-cell restoration and the CD8(+) T-cell expansion that characterize HIV infection.

    We use a cellular automata approach to describe the interactions of the immune system with the human immunodeficiency virus (HIV). We study the evolution of HIV infection, particularly in the clinical latency period. The results we have obtained show the existence of four different behaviours in the plane of death rate of virus-death rate of infected T cell. These regions meet at a critical point, where the virus density and the infected T cell density remain invariant during the evolution of disease. We have introduced two kinds of treatments, the protease inhibitors and the RT inhibitors, in order to study their effects on the evolution of HIV infection. These treatments are powerful in decreasing the density of the virus in the blood and the delay of the AIDS onset.

    Lipodystrophy is a poorly understood condition associated with antiretroviral therapy in HIV infection. The symptoms may include some combination of central fat accumulation, peripheral fat depletion, and metabolic disturbance. A qualitative survey of 33 HIV-infected heterosexual women and gay men with lipodystrophy assessed psychosocial impact and effect on quality of life. Dominant themes included erosion of self-image and self-esteem, problems in social and sexual relations, threats to locus of control, forced HIV disclosure, and demoralization and depression. Another theme was clinicians' minimization of the importance of lipodystrophy. Further research is required to fully understand the psychosocial impact of lipodystrophy and to develop strategies that help individuals cope. PMID:11019453

    Care of patients with HIV infection starts with diagnosis as soon as possible, preferably at or near the time of acute infection. Opportunistic infections, malignancies, and other conditions develop progressively over time, particularly in untreated patients. The AIDS-defining opportunistic infections most common in the United States include Pneumocystis jirovecii pneumonia, Candida esophagitis, toxoplasmic encephalitis, tuberculosis, disseminated Mycobacterium avium complex, cryptococcal meningitis, and cytomegalovirus retinitis. Specific prophylaxis regimens exist for several opportunistic infections, and effective antiretroviral therapy reduces the risk of most others. Other AIDS-defining conditions include wasting syndrome and HIV encephalopathy. AIDS-defining malignancies include Kaposi sarcoma, systemic non-Hodgkin lymphoma, primary central nervous system lymphoma, and invasive cervical cancer. Although not an AIDS-defining condition, anal cancer is common in patients with HIV infection. Other HIV-related conditions include thrombocytopenia, recurrent bacterial respiratory infections, HIV-associated nephropathy, and HIV-associated neurocognitive disorder. PMID:27092563

    OBJECTIVES: The purpose of this study was to describe and compare risky behaviors in HIV-infected youths and adults. METHODS: Records of HIV-infected outpatients were reviewed for the period January 1990 to February 1998. Youths (younger than 22 years at HIV diagnosis and younger than 25 years at study entry, n = 139) were compared with adults (22 years or older at HIV diagnosis or 25 years or older at study entry, n = 2880). Risky behaviors occurring after HIV diagnosis included unsafe sex and needle sharing. RESULTS: Female and male youths were more than twice as likely as adults to engage in risky behavior (adjusted odds ratios of 2.6 and 2.3, respectively). CONCLUSIONS: Both youths and adults continue to engage in risky behaviors after HIV diagnosis. Prospective studies are needed, along with targeted public health campaigns, for youths with HIV and for those at risk of infection. PMID:10630148

    HIV/AIDS and chemical dependency, both of which are complicated by and intertwined with mental illness, are complex, overlapping spheres that adversely influence each other and the overall clinical outcomes of the affected individual [1]. Each disorder individually impacts tens of millions of people, with explosive epidemics described worldwide. Drug users have increased age matched morbidity and mortality for a number of medical and psychiatric conditions. HIV/AIDS, with its immunosuppressed states and direct virologic effects, exacerbate morbidity and mortality further among HIV-infected drug users. This article addresses the adverse consequences of HIV/AIDS, drug injection, the secondary comorbidities of both, and the impact of immunosuppression on presentation of disease as well as approaches to managing the HIV-infected drug user.

    For the first decade and a half after the Human Immunodeficiency Virus (HIV) was first identified, the prognosis for most people infected with HIV was quite poor. Life insurance companies responded accordingly and insurance laboratories developed new means to test for the infection. However, it is now clear that people with HIV infection are living longer and that the majority of deaths occurring among those on treatment are now no longer due to AIDS-defining illnesses. This review examines the results of selected studies which analyzed mortality outcomes in those with HIV infection, the many factors which influence those outcomes, and the limitations in the data and in their applicability to an insurance population.

    A 36-year-old HIV-positive man presented with symptoms of redness, blurred vision and foreign body sensation in his right eye for 3 months. The slit lamp examination revealed deep stromal infiltration with a feathery margin in an otherwise minimal anterior chamber reaction. A corneal scraping was negative. Confocal microscopy demonstrated an abnormal large hyper-reflective oval shape in the corneal stroma. Corneal infiltration did not show improvement after topical, intrastromal and intracameral antifungal treatment. Therapeutic penetrating keratoplasty was performed to eradicate the infection. Corneal button culture and histopathological results confirmed the diagnosis of Penicillium marneffei keratitis. No recurrent infection occurred after corneal transplantation. This appears to be the first report of P. marneffei keratitis in an HIV-infected patient. Although it is an uncommon condition, it should be one of the differential diagnoses in an HIV-infected patient presenting with keratitis. PMID:27535731

    Objective HIV-associated cognitive impairments are prevalent, and are consistent with injury to both frontal cortical and subcortical regions of the brain. The current study aimed to assess the impact of HIV infection on functional connections within the frontostriatal network, circuitry hypothesized to be highly vulnerable to HIV infection. Method Fifteen HIV-positive and 15 demographically matched control participants underwent 6 minutes of resting-state functional magnetic resonance imaging (RS-fMRI). Multivariate group comparisons of age-adjusted estimates of connectivity within the frontostriatal network were derived from BOLD data for dorsolateral prefrontal cortex (DLPFC), dorsal caudate and mediodorsal thalamic regions of interest. Whole-brain comparisons of group differences in frontostriatal connectivity were conducted, as were pairwise tests of connectivity associations with measures of global cognitive functioning and clinical and immunological characteristics (nadir and current CD4 count, duration of HIV infection, plasma HIV RNA). Results HIV – associated reductions in connectivity were observed between the DLPFC and the dorsal caudate, particularly in younger participants (< 50 years, N = 9). Seropositive participants also demonstrated reductions in dorsal caudate connectivity to frontal and parietal brain regions previously demonstrated to be functionally connected to the DLPFC. Cognitive impairment, but none of the assessed clinical/immunological variables, was associated with reduced frontostriatal connectivity. Conclusions In conclusion, our data indicate that a diagnosis of HIV is associated with attenuated intrinsic frontostriatal connectivity. Intrinsic connectivity of this network may therefore serve as a marker of the deleterious effects of HIV infection on the brain, possibly via HIV-associated dopaminergic abnormalities. These findings warrant independent replication in larger studies. PMID:25824201

    Objective To test the hypothesis that the selective serotonin reuptake inhibitor (SSRI) citalopram would down regulate HIV infectivity and that the greatest effects would be seen in people with depression. Depression is a risk factor for morbidity and mortality in HIV/AIDS. Serotonin (5-HT) neurotransmission has been implicated in the pathobiology of depression, and pharmacologic therapies for depression target this system. The 5-HT transporter and 5-HT receptors are widely distributed throughout the central nervous and immune systems. Depression has been associated with suppression of natural killer cells (NK) cells and CD8+ lymphocytes, key regulators of HIV infection. Methods Ex-vivo models for acute and chronic HIV infection were used to study the effects of citalopram on HIV viral infection and replication, in 48 depressed and non-depressed women. For both the acute and chronic infection models, HIV reverse transcriptase (RT) activity was measured in the citalopram treatment condition and the control condition. Results The SSRI significantly downregulated the RT response in both the acute and chronic infection models. Specifically, citalopram significantly decreased the acute HIV infectivity of macrophages. Citalopram also significantly decreased HIV viral replication in the latently infected T-cell line and in the latently infected macrophage cell line. There was no difference in down-regulation by depression status. Conclusions These studies suggest that an SSRI enhances NK/CD8 non-cytolytic HIV suppression in HIV/AIDS and decreases HIV viral infectivity of macrophages, ex vivo, suggesting the need for in vivo studies to determine a potential role for agents targeting serotonin in the host defense against HIV.

    The incidence and severity of infections in childhood is typically greater in males. The basis for these observed sex differences is not well understood, and potentially may facilitate novel approaches to reducing disease from a range of conditions. We here investigated sex differences in HIV-infected children in relation to antiretroviral therapy (ART) initiation and post-treatment outcome. In a South African cohort of 2,101 HIV-infected children, we observed that absolute CD4+ count and CD4% were significantly higher in ART-naïve female, compared to age-matched male, HIV-infected children. Absolute CD4 count and CD4% were also significantly higher in HIV-uninfected female versus male neonates. We next showed that significantly more male than female children were initiated on ART (47% female); and children not meeting criteria to start ART by >5 yrs were more frequently female (59%; p<0.001). Among ART-treated children, immune reconstitution of CD4 T-cells was more rapid and more complete in female children, even after adjustment for pre-ART absolute CD4 count or CD4% (p=0.011, p=0.030, respectively). However, while ART was initiated as a result of meeting CD4 criteria less often in females (45%), ART initiation as a result of clinical disease in children whose CD4 counts were above treatment thresholds occurred more often in females (57%, p<0.001). The main sex difference in morbidity observed in children initiating ART above CD4 thresholds, above that of TB disease, was as a result of wasting and stunting observed in females with above-threshold CD4 counts (p=0.002). These findings suggest the possibility that optimal treatment of HIV-infected children might incorporate differential CD4 treatment thresholds for ART initiation according to sex. PMID:26151555

    HIV treatment requires lifelong adherence to medication regimens that comprise inconvenient scheduling, adverse side effects, and lifestyle changes. Antiretroviral adherence and treatment fatigue have been inextricably linked. Adherence in HIV-infected populations has been well investigated; however, little is known about treatment fatigue. This review examines the current state of the literature on treatment fatigue among HIV populations and provides an overview of its etiology and potential consequences. Standard systematic research methods were used to gather published papers on treatment fatigue and HIV. Five databases were searched using PRISMA criteria. Of 1,557 studies identified, 21 met the following inclusion criteria: (a) study participants were HIV-infected, (b) participants were prescribed antiretroviral medication, (c) the article referenced treatment fatigue, (d) the article was published in a peer-reviewed journal, and (e) text was available in English. Only seven articles operationally defined treatment fatigue, with three themes emerging throughout the definitions: (1) pill burden, (2) loss of desire to adhere to the regimen, and (3) nonadherence to regimens as a consequence of treatment fatigue. Based on these studies, treatment fatigue may be defined as “decreased desire and motivation to maintain vigilance in adhering to a treatment regimen among patients prescribed long-term protocols.” The cause and course of treatment fatigue appear to vary by developmental stage. To date, only structured treatment interruptions have been examined as an intervention to reduce treatment fatigue in children and adults. No behavioral interventions have been developed to reduce treatment fatigue. Further, only qualitative studies have examined treatment fatigue conceptually. Studies designed to systematically assess treatment fatigue are needed. Increased understanding of the course and duration of treatment fatigue is expected to improve adherence

    While Human Immunodeficiency Virus (HIV) infections are reducing in incidence with the advent of Highly Active Anti-retroviral Therapy (HAART), there remain a number of challenges including the existence of reservoirs, drug resistance and anatomical barriers to antiretroviral therapy. To overcome these, smart nanoparticles with stimuli responsive release are proposed for delivery of anti-retroviral agents. The paper highlights the strategic similarities between the design of smart antiretroviral nanocarriers and those optimized for cancer chemotherapy. This includes the development of nanoparticles capable of passive and active targeting as well as those that are responsive to various internal and external triggers. For antiretroviral therapy, the relevant triggers for stimuli responsive release of drugs include semen, enzymes, endosomal escape, temperature and magnetic field. Deriving from the experience of cancer chemotherapy, additional potential triggers are light and ultrasound which remain hitherto unexplored in HIV therapy. In addition, the roles of nanomicrobicides (nanogels) and virus mimetic nanoparticles are discussed from the point of view of prevention of HIV transmission. The challenges associated with translation of smart nanoparticles for HIV infections to realize the Millennium Development Goal of combating HIV infections are discussed.

    It is estimated that the number of HIV infected children globally has increased from 1.6 million in 2001 to 3.3 million in 2012. The number of children below 15 years of age living with HIV has increased worldwide. Published data from recent studies confirmed dramatic survival benefit for infants started anti-retroviral therapy (ART) as early as possible after diagnosis of HI. Early confirmation of HIV diagnosis is required in order to identify infants who need immediate ART. WHO has designed recommendations to improve programs for both early diagnoses of HIV infection and considering ART whenever indicated? It is strongly recommended that HIV virologocal assays for diagnosis of HIV have sensitivity of at least 95% and ideally greater than 98% and specificity of 98% or more under standardized and validated conditions. Timing of virological testing is also important. Infants infected at or around delivery may take short time to have detectable virus. Therefore, sensitivity of virological tests is lower at birth. In utero HIV infection, HIV DNA or RNA can be detected within 48 h of birth and in infants with peripartum acquisition it needs one to two weeks. Finally it is emphasized that all laboratories performing HIV tests should follow available services provided by WHO or CDC for quality assurance programs. Both clinicians and staffs providing laboratory services need regular communications, well-defined SOPs and nationally validated algorithms for optimal use of laboratory tests. Every country should use assays that have been validated by national reference laboratory. PMID:27499768

    Ever since HIV was first diagnosed in human, a great number of scientific works have been undertaken to explore the biological mechanisms involved in the infection and progression of the disease. Several cellular automata (CA) models have been introduced to gain insights into the dynamics of the disease progression but none of them has taken into account effects of certain immune cells such as the dendritic cells (DCs) and the CD8+ T lymphocytes (CD8+ T cells). In this work, we present a CA model, which incorporates effects of the HIV specific immune response focusing on the cell-mediated immunities, and investigate the interaction between the host immune response and the HIV infected cells in the lymph nodes. The aim of our work is to propose a model more realistic than the one in Precharattana et al. (2010) [10], by incorporating roles of the DCs, the CD4+ T cells, and the CD8+ T cells into the model so that it would reproduce the HIV infection dynamics during the primary phase of HIV infection.

    OBJECTIVE: To describe factors related to reproductive decision-making among HIV-infected women. MATERIALS AND METHODS: A sample of HIV-infected women (N=104) who received care at an HIV clinic in the southern United States were interviewed about their reproductive decision-making. Women who became pregnant subsequent to HIV diagnosis were compared to women who did not become pregnant, and women who underwent a sterilization procedure subsequent to HIV diagnosis were compared to women who did not get sterilized. RESULTS: Compared to women who did not get pregnant after receiving an HIV diagnosis, women who became pregnant were more likely to be young, single, diagnosed earlier in the epidemic and to have more recently used a noninjecting drug. Among women who did not get pregnant, 63% reported their diagnosis greatly affected that decision. Having a partner who wants more children was not associated with pregnancy. Compared to women who did not get sterilized after learning their HIV status, women who did get sterilized tended to be Baptist and already had a prior live birth. Neither a woman's desire nor her partner's desire for more children was associated with sterilization. CONCLUSIONS: HIV is an important influence on HIV-infected women's reproductive choices, regardless of the decision being made. Reproductive counseling by HIV care providers needs to be sensitive to all the issues faced by these women. PMID:16353661

    Summary HIV infection can result in stroke via several mechanisms, including opportunistic infection, vasculopathy, cardioembolism, and coagulopathy. However, the occurrence of stroke and HIV infection might often be coincidental. HIV-associated vasculopathy describes various cerebrovascular changes, including stenosis and aneurysm formation, vasculitis, and accelerated atherosclerosis, and might be caused directly or indirectly by HIV infection, although the mechanisms are controversial. HIV and associated infections contribute to chronic inflammation. Combination antiretroviral therapies (cART) are clearly beneficial, but can be atherogenic and could increase stroke risk. cART can prolong life, increasing the size of the ageing population at risk of stroke. Stroke management and prevention should include identification and treatment of the specific cause of stroke and stroke risk factors, and judicious adjustment of the cART regimen. Epidemiological, clinical, biological, and autopsy studies of risk, the pathogenesis of HIV-associated vasculopathy (particularly of arterial endothelial damage), the long-term effects of cART, and ideal stroke treatment in patients with HIV are needed, as are antiretrovirals that are without vascular risk.

    Both survival with HIV and rates of perinatal HIV infection have significantly declined during the past decade, due to antiretroviral therapies that interrupt HIV transmission to the fetus and newborn. Although HIV is no longer routinely fatal to mothers or transmitted to fetuses, and the testing of newborns for HIV has been improved, evidence about HIV-infected mothers' experiences during the months of their infants' HIV testing predates these improvements. This qualitative study on 16 mothers was an analysis of interviews conducted several weeks after testing was completed and all infants had been determined to be uninfected. Mothers reported that their experiences evolved during the months of testing. Initial reactions included maternal trauma and guilt associated with infant testing. They then reported learning to cope with the roller coaster ride of repeated testing with the help of information from clinicians. By the end of the testing period, ambiguity began to resolve as they engaged in tentative maternal-infant attachment and expressed desire for a sense of normalcy. Need for support and fear of stigma persisted throughout. These findings expand current knowledge about this experience and suggest clinical strategies to guide HIV-infected women during this stressful period. PMID:25739368

    Antiretroviral therapy in children has expanded dramatically in low-income and middle-income countries. The World Health Organization revised its pediatric HIV guidelines to recommend initiation of antiretroviral therapy in all HIV-infected children younger than 2 years, regardless of CD4 count or clinical stage. The number of children starting life-long antiretroviral therapy should therefore expand dramatically over time. The early initiation of antiretroviral therapy has indisputable benefits for children, but there is a paucity of definitive information on the potential adverse effects. In this review, a comprehensive literature search was conducted to provide an overview of our knowledge about the complications of treating pediatric HIV. Antiretroviral therapy in children, as in adults, is associated with enhanced survival, reduction in opportunistic infections, improved growth and neurocognitive function, and better quality of life. Despite antiretroviral therapy, HIV-infected children may continue to lag behind their uninfected peers in growth and development. In addition, epidemic concurrent conditions, such as tuberculosis, malaria, and malnutrition, can combine with HIV to yield more rapid disease progression and poor treatment outcomes. Additional studies are required to evaluate the long-term effects of antiretroviral therapy in HIV-infected infants, children, and adolescents, particularly in resource-limited countries where concomitant infections and conditions may enhance the risk of adverse effects. There is an urgent need to evaluate drug-drug interactions in children to determine optimal treatment regimens for both HIV and coinfections. PMID:22138766

    Stress has significant adverse impacts on health outcomes of HIV-infected patients. Our study explored coping with stress strategies by HIV-infected Iranian patients. A qualitative content analysis study was conducted at the Consultation Clinic of HIV at the Imam Khomeini Hospital in Tehran, Iran in 2012. Twenty-six semi-structured in-depth interviews were done. Participants were asked about coping strategies for stress. After the first interview, continuous analysis of data was started and continued up to data saturation. Results showed that participants used two categories of strategies (emotion-based coping and problem-based coping) to cope with stress. Emotion-based coping had two sub-themes: adaptive and maladaptive. The problem-based coping category had three sub-themes: participation in education sessions, adherence to medication, and efforts to maintain a healthy lifestyle. Explanations of different strategies available to HIV-infected patients to cope with stress may help develop tailored interventions to improve the psychological conditions of people living with HIV.

    Gastrointestinal symptoms are commonly seen in patients with established AIDS. We examined the charts of 258 HIV-infected patients attending our HIV outpatient clinic to determine: (1) the frequency of gastrointestinal symptoms in unselected HIV-infected patients and (2) if there are any predictors of the development of symptoms in initially asymptomatic patients. We found the overall frequency of gastrointestinal symptoms at initial presentation in our ambulatory, predominantly homosexual population of HIV-infected patients was 35% (95% CI 30-40%) with 19% having anorexia, 15% weight loss, 14% diarrhea, and 5% dysphagia. There was no association between the presence of symptoms and stool parasites, which were found in 51% of patients. In 165 patients who were initially asymptomatic, 72% subsequently developed symptoms over 36 months of actuarial follow-up. Patients with initial T4 counts < 500 were more likely to develop symptoms. Patients with a greater degree of immunosuppression as indicated by a lower T4 count, are more likely to develop gastrointestinal symptoms. PMID:8102092

    Appropriate screening for HIV infection is the cornerstone of HIV-related care. There have been several recent changes in testing technology and screening recommendations. The US Preventive Services Task Force recommends universal HIV screening at least once for adolescents and adults ages 15 to 65 years, and additional screening for patients at higher risk, although evidence is insufficient to determine optimum rescreening intervals. All pregnant women should be screened for HIV infection in the first trimester, and pregnant women at high risk should be screened again in the third trimester. The Centers for Disease Control and Prevention recommends use of an algorithm using fourth-generation tests for screening; this decreases the window period between infection and detection to as few as 14 days, thereby reducing the number of false-negative results. Home HIV testing kits, which require follow-up confirmatory testing, also are available. Clinicians should be aware of HIV-specific laws in their states, including those criminalizing HIV exposure and transmission. Thorough medical and laboratory evaluations are essential at initiation of care for patients with HIV infection, along with appropriate follow-up monitoring, as recommended in various guidelines.

  17. Apoptosis and HIV infection: about molecules and genes.

    PubMed

    During the evolution, the immune system has developed several strategies to fight viral infections. Apoptosis, autophagy and necrosis are different types of cell death that play a main role in the interactions between infective agents and the host, since they are often important defence mechanisms that have to avoid the spreading of the infection. In turn, viruses have evolved numerous ways to evade the host immune system by influencing the behaviour and functionality of several components. HIV infects and kills CD4+ T helper lymphocytes, preferentially those that are antigen-specific, but also encodes proteins with apoptotic capacities, including gp120, gp160, Tat, Nef, Vpr, Vpu, Vif and, last but not least, the viral protease. This latter protein can kill infected and uninfected lymphocytes through the action of several host molecules, mainly members of the tumor necrosis factor family, or via the mitochondrial apoptotic pathway. The proinflammatory state that is characteristic of both the acute and chronic phase of HIV infection facilitates cell death, and is an additional cause of immune damage. Potent antiretroviral drugs that are largely use in therapy can reduce apoptosis by different mechanisms, that not only include the diminished production of the virus by infected cells and the subsequent reduction of inflammation, but also a direct action on the viral protease. The role of the host genetic background is finally crucial in understanding the process of cell death in HIV infection. PMID:18220834

    Research on the relationship between migration and HIV infection in sub-Saharan Africa often suggests that migrants are at higher risk of HIV infection because they are more likely to engage in risk behavior than non-migrants, and tend to move to areas with a relatively higher HIV prevalence. While migration may be a risk factor for HIV infection, I instead focus on the possibility that the HIV positive are more likely to migrate. Using a longitudinal dataset of permanent rural residents and migrants from Malawi, I find that migrants originating from rural areas are indeed more likely than non-migrants to be HIV positive and to have engaged in HIV risk behavior. The increased HIV risk among migrants may be due to the selection of HIV positive individuals into migration; I find that HIV positive individuals are more likely migrate than those who are HIV negative. The explanation for this phenomenon appears to be marital instability, which occurs more frequently among HIV positive individuals and leads to migration after marital change. PMID:22109083

    Introduction With improved access to antiretroviral therapy (ART), HIV infection is becoming a chronic illness. Preliminary data suggest that HIV-infected children have a higher risk of disabilities, including hearing impairment, although data are sparse. This study aimed to estimate the prevalence and types of hearing loss in HIV-infected children in Lilongwe, Malawi. Methods This was a cross-sectional survey of 380 HIV-infected children aged 4–14 years attending ART clinic in Lilongwe between December 2013-March 2014. Data was collected through pediatric quality of life and sociodemographic questionnaires, electronic medical record review, and detailed audiologic testing. Hearing loss was defined as >20 decibels hearing level (dBHL) in either ear. Predictors of hearing loss were explored by regression analysis generating age- and sex-adjusted odds ratios. Children with significant hearing loss were fitted with hearing aids. Results Of 380 patients, 24% had hearing loss: 82% conductive, 14% sensorineural, and 4% mixed. Twenty-one patients (23% of those with hearing loss) were referred for hearing aid fitting. There was a higher prevalence of hearing loss in children with history of frequent ear infections (OR 7.4, 4.2–13.0) and ear drainage (OR 6.4, 3.6–11.6). Hearing loss was linked to history of WHO Stage 3 (OR 2.4, 1.2–4.5) or Stage 4 (OR 6.4, 2.7–15.2) and history of malnutrition (OR 2.1, 1.3–3.5), but not to duration of ART or CD4. Only 40% of caregivers accurately perceived their child’s hearing loss. Children with hearing impairment were less likely to attend school and had poorer emotional (p = 0.02) and school functioning (p = 0.04). Conclusions There is an urgent need for improved screening tools, identification and treatment of hearing problems in HIV-infected children, as hearing loss was common in this group and affected school functioning and quality of life. Clear strategies were identified for prevention and treatment, since most

    Objective: Several pieces of evidence indicate that HIV-infected adults undergo premature aging. The effect of HIV and antiretroviral therapy (ART) exposure on the aging process of HIV-infected children may be more deleterious since their immune system coevolves from birth with HIV. Design: Seventy-one HIV-infected (HIV+), 65 HIV-exposed-uninfected (HEU), and 56 HIV-unexposed-uninfected (HUU) children, all aged 0–5 years, were studied for biological aging and immune senescence. Methods: Telomere length and T-cell receptor rearrangement excision circle levels were quantified in peripheral blood cells by real-time PCR. CD4+ and CD8+ cells were analysed for differentiation, senescence, and activation/exhaustion markers by flow cytometry. Results: Telomere lengths were significantly shorter in HIV+ than in HEU and HUU children (overall, P < 0.001 adjusted for age); HIV+ ART-naive (42%) children had shorter telomere length compared with children on ART (P = 0.003 adjusted for age). T-cell receptor rearrangement excision circle levels and CD8+ recent thymic emigrant cells (CD45RA+CD31+) were significantly lower in the HIV+ than in control groups (overall, P = 0.025 and P = 0.005, respectively). Percentages of senescent (CD28−CD57+), activated (CD38+HLA-DR+), and exhausted (PD1+) CD8+ cells were significantly higher in HIV+ than in HEU and HUU children (P = 0.004, P < 0.001, and P < 0.001, respectively). Within the CD4+ cell subset, the percentage of senescent cells did not differ between HIV+ and controls, but programmed cell death receptor-1 expression was upregulated in the former. Conclusions: HIV-infected children exhibit premature biological aging with accelerated immune senescence, which particularly affects the CD8+ cell subset. HIV infection per se seems to influence the aging process, rather than exposure to ART for prophylaxis or treatment. PMID:26990630

    BACKGROUND Clients with HIV infection have been conceptualized as a resilient population. Although a few researchers have documented resilience among clients with HIV infection, a theory of resilience in the context of HIV infection has not been developed. The purpose of this study was to describe the process by which resilience occurs for clients in the context of HIV infection. METHOD Grounded theory methodology was used to sample and analyze data from 15 qualitative interviews with adults with HIV infection. Data were collected until saturation was reached. RESULTS A theory, motivation, management, and mastery, a description of the process by which resilience occurs in the context of HIV infection, emerged from the data. CONCLUSION Many clients living with HIV infection are resilient, despite the physical, psychological, and social challenges of this chronic illness. Nursing interventions to promote resilience among clients with HIV infection should be directed toward identification of client motivation factors and disease management strategies that may influence health outcomes of people living with HIV infection.

    We sought to identify the socioeconomic impact on people living with HIV (PLWH) in Sudan. Focus group discussions were used to collect data and identify the most outstanding domains of HIV impact on PLWH and the survival mechanisms that may be common to a group of diverse HIV-infected persons (n = 30). The findings indicated that the most striking financial and social impacts were due to stigma associated with HIV in the conservative Sudanese society, which led to loss of work with all its consequences (e.g., children's education and health care expenses were affected). The socioeconomic impacts of HIV on infected populations are discussed, and suggestions for possible interventions to mitigate harmful impacts and stigma within the society, the workplace, and health care settings are highlighted. We concluded that HIV has intensified the existing problems of infected people, contributing to their vulnerability to poverty. PMID:26190419

    This was a qualitative study, based on the Social Representations Theory, with professionals that work in primary care, about the risk of HIV infection to which they are exposed in their quotidian work routine. Twelve physicians and nurses who work in two Health Centers in the city of Belo Horizonte, MG, Brazil, were interviewed. The final analysis, carried out using the saturation of information criterion, was based on the method proposed by Structural Analysis of Narrative. The results show that the health professionals interviewed knew the infection risk in their work routine, representing it as very low in primary care, because they relate it to technological complexity which they consider does not exist in the level of assistance in which they work. They believed that the use of personal protection equipment may minimize the risks and that, nowadays, no primary care professional refuses to attend a patient due to fear of infection, even if not using all the recommended precautions.

    High adherence is critical for achieving clinical benefits of HIV antiretroviral therapy (ART) and particularly challenging for children. We conducted 35 qualitative interviews with caregivers of HIV-infected Ugandan children who were followed in a longitudinal study of real-time ART adherence monitoring; 18 participants had undetectable HIV RNA, while 17 had detectable virus. Interviews blinded to viral suppression status elicited information on adherence experiences, barriers and facilitators to adherence, and social support. Using an inductive content analytic approach, we identified 'lack of resources,' 'Lazarus effect,' 'caregiver's sense of obligation and commitment,' and 'child's personal responsibility' as categories of influence on adherence, and defined types of caregiver social support. Among children with viral suppression, high hopes for the child's future and ready access to private instrumental support appeared particularly important. These findings suggest clinical counseling should explore caregivers' views of their children's futures and ability to access support in overcoming adherence barriers. PMID:25323679

    Introduction As highly active antiretroviral therapy (HAART) transforms human immunodeficiency virus (HIV) into a manageable chronic disease, new challenges are emerging in treating children born with HIV, including a number of risks to their physical and psychological health due to HIV infection and its lifelong treatment. Methods We conducted a literature review to evaluate the evidence on the physical and psychological effects of perinatal HIV (PHIV+) infection and its treatment in the era of HAART, including major chronic comorbidities. Results and discussion Perinatally infected children face concerning levels of treatment failure and drug resistance, which may hamper their long-term treatment and result in more significant comorbidities. Physical complications from PHIV+ infection and treatment potentially affect all major organ systems. Although treatment with antiretroviral (ARV) therapy has reduced incidence of severe neurocognitive diseases like HIV encephalopathy, perinatally infected children may experience less severe neurocognitive complications related to HIV disease and ARV neurotoxicity. Major metabolic complications include dyslipidaemia and insulin resistance, complications that are associated with both HIV infection and several ARV agents and may significantly affect cardiovascular disease risk with age. Bone abnormalities, particularly amongst children treated with tenofovir, are a concern for perinatally infected children who may be at higher risk for bone fractures and osteoporosis. In many studies, rates of anaemia are significantly higher for HIV-infected children. Renal failure is a significant complication and cause of death amongst perinatally infected children, while new data on sexual and reproductive health suggest that sexually transmitted infections and birth complications may be additional concerns for perinatally infected children in adolescence. Finally, perinatally infected children may face psychological challenges, including

    Ukraine is a leader in Europe in the prevalence of HIV infection. There are up to 270 thousand people, who are living with HIV. Since 1987, in Ukraine, 33,149 HIV-infected people died. During the first six months of 2013, of all the dead, who were suffering from HIV and in need of antiretroviral treatment (ART) at the time of death, 41% received treatment and only 5.7% received ART for more than one year. Specialists of Kiev Regional AIDS Center analyzed mortality among the patients of the centre, in order to determine the most frequent cause of death, set the group most at risk and to develop effective measures to reduce mortality among HIV-infected patients. In Kiev AIDS Center, 10,000 people are under medical observation and 4004 of them are taking ART. During 2013, 305 persons died: 217 were women and 88 were men which included 3 children under 14 years. Most of the dead - 272 (89%) were aged 25-49. Among the total number of the dead, 125 people (41%) were receiving ART, 53 of them (17%) were receiving ART for at least one year and 39 of them (13%) were receiving ART for less than one month. Hundred and fifty-eight people (52%) required ART and 22 (7%) did not need therapy. Hundred and ninety-two patients (63%) were in four clinical stage of HIV infection. Hundred and ten of them had HIV+TB co-infection. Twenty patients died due to TB and 12 patients died due to hepatitis b virus/hepatitis c virus (HBV/HCV). Among these patients, 87 people (39%) were taking ART and 136 persons (61%) were in need of ART, but did not get it. Nineteen patients were diagnosed with cancer. Sixteen patients, who were co-infected HIV+TB had a CD4 cell count of more than 300. Based on this analysis, we can conclude that the main causes of high mortality among HIV-infected patients in 2013 were late diagnosis of HIV, besides a large number (52%) of patients, who were in need of ART did not take it. A large number (40%) among those who died were patients co-infected with HIV+TB, HIV

    As the number of human immunodeficiency virus (HIV) infected patients has increased in the U.S., the number of infected patients treated for end-stage renal disease (ESRD) has stabilized at about 1 to 2% of the hemodialyzed population. Little has been written regarding the role of continuous ambulatory peritoneal dialysis (CAPD) in the treatment of HIV infected patients with ESRD. To evaluate the effectiveness of CAPD as a long term therapy for HIV infected patients with ESRD, we reviewed our ESRD program's experience. We entered 392 patients from its inception in February 1984 until April 1992. Thirty-one, or 7.9% of our population were HIV infected. Twenty, or 64.5% had stage IV infection. Patients were entered into our chronic hemodialysis (HD) or CAPD program according to standard clinical criteria. Eight HIV infected patients elected to start CAPD, while 23 patients were treated exclusively with HD. The proportion of stage IV infected patients was similar in both treatment modality groups. HIV infected ESRD patients were younger than non-HIV infected patients (37.5 +/- 9.7 vs. 49.8 +/- 15.7 years, respectively, P < 0.0001) at the start of treatment. We used Cox regression techniques to analyze survival data. Mean survival time for our entire non-HIV infected ESRD population (N = 361) was 44.0 +/- 33.9 months. Mean survival time for HIV infected patients with ESRD was 15.5 +/- 9.9 months. Median survival for HIV infected ESRD patients was 13 months compared to 38 months for the non-infected population. As expected, mean survival time in HIV infected ESRD patients was significantly diminished compared to non-infected ESRD patients (P < 0.0001).(ABSTRACT TRUNCATED AT 250 WORDS) PMID:8377381

    PubMed

    Kroger, F

    1991-01-01

    This essay discusses the rationale for targeting HIV prevention programs to the general public, as opposed to focusing strictly on high-risk populations. The author first considers varying definitions of the term "general public," then explains the goal of general public education programs. Additionally, the author lays down the theoretical foundations of general audience education programs and weights related research findings. Finally, he offers recommendations for future practice. Noting the complex socioecological elements involved in health behavior, the author argues in favor of a broad definition for the general public. This broad outlook allows programs to still target high-risk population while not bypassing low-risk persons, who are sometimes treated as irrelevant because they do not contribute to excess morbidity or mortality. When it comes to HIV educational programs for the general public, their goals should be to instruct the public on how the virus is transmitted, to allay unfounded fears, and to increase the level of support for AIDS prevention and control. Such a program would require a theoretical basis drawn from multiple sources: health education, health communication, clinical and social psychology, and social marketing. The author concludes by proving recommendations designed to reinforce existing programs: 1) strengthen efforts to ensure that all people are educated about HIV and to encourage people to treat AIDS patients with compassion; 2) continue to explore for the most effective communication channels; 3) strengthen the communication infrastructure for those who are disenfranchised from health education; and 4) strengthen evaluation efforts of health communication programs.

    Background Maternal morbidity and mortality among HIV-infected women is a global concern. This study compared mortality and health outcomes of HIV-infected and HIV-uninfected mothers at 18–20 months postpartum within routine prevention of mother-to-child transmission of HIV (PMTCT) services in a rural district in Malawi. Methods A retrospective cohort study of mother-child dyads at 18–20 months postpartum in Zomba District. Data on socio-demographic characteristics, service uptake, maternal health outcomes and biometric parameters were collected. Results 173 HIV-infected and 214 HIV-uninfected mothers were included. HIV-specific cohort mortality at 18–20 months postpartum was 42.4 deaths/1000 person-years; no deaths occurred among HIV-uninfected women. Median time to death was 11 months post-partum (range 3–19). Women ranked their health on a comparative qualitative scale; HIV-infected women perceived their health to be poorer than did HIV-uninfected women (RR 2.4; 95% CI 1.6–3.7). Perceived maternal health status was well correlated with an objective measure of functional status (Karnofsky scale; p<0.001). HIV-infected women were more likely to report minor (RR 3.8; 95% CI 2.3–6.4) and major (RR 6.2; 95% CI 2.2–17.7) signs or symptoms of disease. In multivariable analysis, HIV-infected women remained twice as likely to report poorer health [adjusted OR (aOR) 2.3; 95% CI 1.4–3.6], as did women with low BMI (aOR 2.1; 95% CI 1.1–4.0) and scoring lowest on the welfare scale (aOR 2.0; 95% CI 1.1–3.8). Conclusions HIV-infected women show increased mortality and morbidity at 18–20 months postpartum. In our rural Malawian operational setting, where there is documented under-application of ART and poor adherence to PMTCT services, these results support attention to optimizing maternal participation in PMTCT programs.

    OBJECTIVE: To describe the health, social environment, medical care received and satisfaction with medical care of HIV-infected women in British Columbia. DESIGN: Self-administered 75-item questionnaire distributed by mail or in person between March 1994 and February 1996 through community AIDS organizations and physicians' offices. SETTING: British Columbia. PARTICIPANTS: A total of 110 HIV-positive women. OUTCOME MEASURES: Sociodemographic data, risk factors for HIV infection, details about HIV testing, health status and medical treatment, use of health care services, degree of satisfaction with medical care and psychosocial stressors. RESULTS: Most of the women surveyed were aged 25 to 39 years (70.0%), were Canadian born (76.4%) and were white (80.9%). Over one-third did not complete high school, and half had an annual household income of less than $20,000. Of the 110 women 51.8% had children, who were HIV-positive in 12.3% of cases. The most frequently reported risk factor for HIV infection was sex with a man (49.1%); 19.1% reported both sex with a man and injection drug use, and 12.7% reported injection drug use only. Seventy-five women indicated that they had become infected through sex with a man, with or without injection drug use. Of these, 65 indicated whether or not this was the result of sexual assault or rape; 8 (12.3%) answered affirmatively. Of the 81 women who responded to the question regarding prior sexual assault or abuse, 43 (53.1%) reported being sexually assaulted as an adult, 35 (43.2%) reported being sexually abused as a child, and 22 (27.2%) reported being sexually abused or assaulted both as a child and as an adult. Women who were sexually abused as a child were more likely than those who were not abused as a child to have injection drug use as a risk factor (54.3% v. 7.5%). Menstrual cycle changes were reported by 70.1% of the respondents. Most women stated that they had not received adequate pre- or post-test counselling, and 47.0% were

    Background Factors associated with mortality in HIV-infected people in sub-Saharan Africa are widely reported. However rural–urban disparities and their association with all-cause mortality remain unclear. Furthermore, commonly used classical Cox regression ignores unmeasured variables and frailty. Objective To incorporate frailty in assessing factors associated with mortality in HIV-infected people in rural and urban South Africa. Design Using data from a prospective cohort following 6,690 HIV-infected participants from Soweto (urban) and Mpumalanga (rural) enrolled from 2003 to 2010; covariates of mortality were assessed by the integrated nested Laplace approximation method. Results We enrolled 2,221 (33%) rural and 4,469 (67%) urban participants of whom 1,555 (70%) and 3,480 (78%) were females respectively. Median age (IQR) was 36.4 (31.0–44.1) in rural and 32.7 (28.2–38.1) in the urban participants. The mortality rate per 100 person-years was 11 (9.7–12.5) and 4 (3.6–4.5) in the rural and urban participants, respectively. Compared to those not on HAART, rural participants had a reduced risk of mortality if on HAART for 6–12 (HR: 0.20, 95% CI: 0.10–0.39) and >12 months (HR: 0.10, 95% CI: 0.05–0.18). Relative to those not on HAART, urban participants had a lower risk if on HAART >12 months (HR: 0.35, 95% CI: 0.27–0.46). The frailty variance was significant and >1 in rural participants indicating more heterogeneity. Similarly it was significant but <1 in the urban participants indicating less heterogeneity. Conclusion The frailty model findings suggest an elevated risk of mortality in rural participants relative to the urban participants potentially due to unmeasured variables that could be biological, socio–economic, or healthcare related. Use of robust methods that optimise data and account for unmeasured variables could be helpful in assessing the effect of unknown risk factors thus improving patient management and care in South Africa and

    Pneumocystis jiroveci (formerly P. carinii) is an opportunistic fungus responsible for pneumonia in immunocompromised patients. Pneumocystosis in non-HIV-infected patients differs from AIDS-associated pneumocystosis in mostly two aspects: diagnosis is more difficult, and prognosis is worse. Hence, efforts should be made to target immunocompromised patients at higher risk of pneumocystosis, so that they are prescribed long-term, low-dose, trimethoprime-sulfamethoxazole, highly effective for pneumocystosis prophylaxis. Patients at highest risk include those with medium and small vessels vasculitis, lymphoproliferative B disorders (chronic or acute lymphocytic leukaemia, non-Hodgkin lymphoma), and solid cancer on long-term corticosteroids. Conversely, widespread use of prophylaxis in all patients carrier of inflammatory diseases on long-term corticosteroids is not warranted. The management of pneumocystosis in non-AIDS immunocompromised patients follows the rules established for AIDS patients. The diagnosis relies on the detection of P. jiroveci cyst on respiratory samples, while PCR does not reliably discriminate infection from colonization, in 2015. High-doses trimethoprim-sulfamethoxazole is, by far, the treatment of choice. The benefit of adjuvant corticosteroid therapy for hypoxic patients, well documented in AIDS patients, has a much lower level of evidence in non-HIV-infected patients, most of them being already on corticosteroid by the time of pneumocystosis diagnosis anyway. However, based on its striking impact on morbi-mortality in AIDS patients, adjuvant corticosteroid is recommended in hypoxic, non-HIV-infected patients with pneumocystosis by many experts and scientific societies.

    To obtain better understanding of the nature and cost of health care related to human immunodeficiency virus (HIV) infection, medical payment records were analyzed for 204 men, women, and children older than 60 months who had indications of HIV infection. The records were those of Michigan Medicaid, the General Assistance Medical Program, and the Resident County Hospitalization Program, with service dates on or after January 1, 1984, and which were processed by November 30, 1987. Patient payment records were coded according to whether the patient's condition was considered to be pre-HIV, HIV unrelated, possibly HIV related, or HIV related. Average monthly payments were found to be $150 for pre-HIV patient payment records, $114 for those HIV unrelated, $57 for those possibly related, and $1,213 for those related to HIV infection. HIV-related monthly payments rose from about $1,500 per month in the period 3 months prior to the patient's death to more than $8,000 in the last month of life. Men were found to have twice as many claims as women, and men's claims cost about three times as much. A higher percentage of women than men (91 percent versus 37 percent) received pre-HIV paid services, indicating a higher percentage of women were at least initially receiving Medicaid for reasons other than an HIV-related disability. Diagnostic categories that accounted for the bulk of the HIV-related health care utilization included infectious and parasitic diseases, acquired immunodeficiency syndrome, diseases of the respiratory system, and non-HIV-specific immunity disorders. Inpatient hospitalization accounted for more than 75 percent of the payments, followed by physician costs (11 percent), pharmacy costs (5 percent), and outpatient costs (3 percent). A total of 45, or about 22 percent of the recipients, received zidovudine (AZT) prescriptions at an average monthly cost of $404. PMID:2508170

    Background Urogenital schistosomiasis, caused by infection with Schistosoma haematobium, is widespread and causes substantial morbidity on the African continent. The infection has been suggested as an unrecognized risk factor for incident HIV infection. Current guidelines recommend preventive chemotherapy, using praziquantel as a public health tool, to avert morbidity due to schistosomiasis. In individuals of reproductive age, urogenital schistosomiasis remains highly prevalent and, likely, underdiagnosed. This comprehensive literature review was undertaken to examine the evidence for a cause-effect relationship between urogenital schistosomiasis and HIV/AIDS. The review aims to support discussions of urogenital schistosomiasis as a neglected yet urgent public health challenge. Methodology/Principal Findings We conducted a systematic search of the literature including online databases, clinical guidelines, and current medical textbooks. We describe plausible local and systemic mechanisms by which Schistosoma haematobium infection could increase the risk of HIV acquisition in both women and men. We also detail the effects of S. haematobium infection on the progression and transmissibility of HIV in co-infected individuals. We briefly summarize available evidence on the immunomodulatory effects of chronic schistosomiasis and the implications this might have for populations at high risk of both schistosomiasis and HIV. Conclusions/Significance Studies support the hypothesis that urogenital schistosomiasis in women and men constitutes a significant risk factor for HIV acquisition due both to local genital tract and global immunological effects. In those who become HIV-infected, schistosomal co-infection may accelerate HIV disease progression and facilitate viral transmission to sexual partners.

    Background—A transient expansion of the CD8+ T cell pool normally occurs in the early phase of HIV infection. Persistent expansion of this pool is observed in two related settings: diffuse infiltrative lymphocytosis syndrome (DILS) and HIV associated CD8+ lymphocytosis syndrome. Aim—To investigate a group of HIV infected patients with CD8+ lymphocytosis syndrome with particular emphasis on whether monoclonality was present. Methods—A group of 18 patients with HIV-1 infection and persistent circulating CD8+ lymphocytosis was compared with 21 HIV positive controls. Serum samples were tested for antinuclear antibodies, antibodies to extractable nuclear antigens, immunoglobulin levels, paraproteins, human T lymphotropic virus type 1 (HTLV-1), Epstein-Barr virus, and cytomegalovirus serology. Lymphocyte phenotyping and HLA-DR typing was performed, and T cell receptor (TCR) gene rearrangement studies used to identify monoclonal populations of T cells. CD4+ and CD8+ subsets of peripheral blood lymphocytes were purified to determine whether CD8+ populations inhibited HIV replication in autologous CD4+ cells. Results—A subgroup of patients with HIV-1 infection was found to have expanded populations of CD8+ T cell large granular lymphocytes persisting for 6 to 30 months. The consensus immunophenotype was CD4- CD8+ DRhigh CD11a+ CD11c+ CD16- CD28± CD56- CD57+, consistent with typical T cell large granular lymphocytes expressing cellular activation markers. Despite the finding of monoclonal TCR gene usage in five of 18 patients, there is evidence that the CD8+ expansions are reactive populations capable of mediating non-cytotoxic inhibition of HIV replication. Conclusions—A subgroup of HIV positive patients has CD8+ lymphocytosis, but despite the frequent occurrence of monoclonal TCR gene usage there is evidence that this represents an immune response to viral infection rather than a malignant disorder. Key Words: HIV infection • CD8+ lymphocytosis • clonality

    Previous studies of the effect of ART on gene expression in HIV-infected individuals have identified small numbers of modulated genes. Since these studies were underpowered or cross-sectional in design, a paired analysis of peripheral blood mononuclear cells (PBMCs), isolated before and after ART, from a robust number of HIV-infected patients (N=32) was performed. Gene expression was assayed by microarray and 4,157 differentially expressed genes (DEGs) were identified following ART using multivariate permutation tests. Pathways and Gene Ontology (GO) terms over-represented for DEGs reflected the transition from a period of active virus replication before ART to one of viral suppression (e.g., repression of JAK-STAT signaling) and possible prolonged drug exposure (e.g. oxidative phosphorylation pathway) following ART. CMYC was the DEG whose product made the greatest number of interactions at the protein level in protein interaction networks (PINs), which has implications for the increased incidence of Hodgkin’s lymphoma (HL) in HIV-infected patients. The differential expression of multiple genes was confirmed by RT-qPCR including well-known drug metabolism genes (e.g., ALOX12 and CYP2S1). Targets not confirmed by RT-qPCR (i.e., GSTM2 and RPL5) were significantly confirmed by droplet digital (ddPCR), which may represent a superior method when confirming DEGs with low fold changes. In conclusion, a paired design revealed that the number of genes modulated following ART was an order of magnitude higher than previously recognized. PMID:23933117

  18. Amyloid and tau cerebrospinal fluid biomarkers in HIV infection

    PubMed Central

    2009-01-01

    Background Because of the emerging intersections of HIV infection and Alzheimer's disease, we examined cerebrospinal fluid (CSF) biomarkers related of amyloid and tau metabolism in HIV-infected patients. Methods In this cross-sectional study we measured soluble amyloid precursor proteins alpha and beta (sAPPα and sAPPβ), amyloid beta fragment 1-42 (Aβ1-42), and total and hyperphosphorylated tau (t-tau and p-tau) in CSF of 86 HIV-infected (HIV+) subjects, including 21 with AIDS dementia complex (ADC), 25 with central nervous system (CNS) opportunistic infections and 40 without neurological symptoms and signs. We also measured these CSF biomarkers in 64 uninfected (HIV-) subjects, including 21 with Alzheimer's disease, and both younger and older controls without neurological disease. Results CSF sAPPα and sAPPβ concentrations were highly correlated and reduced in patients with ADC and opportunistic infections compared to the other groups. The opportunistic infection group but not the ADC patients had lower CSF Aβ1-42 in comparison to the other HIV+ subjects. CSF t-tau levels were high in some ADC patients, but did not differ significantly from the HIV+ neuroasymptomatic group, while CSF p-tau was not increased in any of the HIV+ groups. Together, CSF amyloid and tau markers segregated the ADC patients from both HIV+ and HIV- neuroasymptomatics and from Alzheimer's disease patients, but not from those with opportunistic infections. Conclusions Parallel reductions of CSF sAPPα and sAPPβ in ADC and CNS opportunistic infections suggest an effect of CNS immune activation or inflammation on neuronal amyloid synthesis or processing. Elevation of CSF t-tau in some ADC and CNS infection patients without concomitant increase in p-tau indicates neural injury without preferential accumulation of hyperphosphorylated tau as found in Alzheimer's disease. These biomarker changes define pathogenetic pathways to brain injury in ADC that differ from those of Alzheimer's disease

    Objective: To study the cardiac abnormalities in HIV infected patients in relation to the clinical stage of the disease and the immunological status of the patients. Methods: A total 75 consecutive patients tested for HIV on the basis of clinical suspicion of the disease from July to September 1996 at the University Hospital Centre, Yaounde, Cameroon were recruited. The patients were classified into AIDS, HIV positive non-AIDS, and HIV negative according to clinical findings and outcome of ELISA and western blot testing. Every patient underwent a clinical examination, two dimensional and M-mode echocardiography, and blood lymphocyte typing. Results: Dilated cardiomyopathy occurred in 7/30 (23.33%) AIDS patients, 1/24 (4.17%) HIV positive non-AIDS patient, but in none of the HIV negative patients. Other echocardiographic abnormalities included pericardial separation, effusion, thickening, and mitral valve prolapse. Although these abnormalities were more frequent in HIV infected patients, the differences did not reach levels of statistical significance. Dilated cardiomyopathy occurred in six (31.58%) of the patients with a CD4 cell count ≤100/mm3 and two (6.06%) in those with absolute CD4 counts >100/mm3 (χ2 = 4.02, p = 0.03). Conclusions: Cardiovascular abnormalities are frequent in African HIV infected patients but clinically discrete. Low CD4 cell counts are associated with dilated cardiomyopathy. These abnormalities should be expected with greater frequency in cardiological clinical practice as management of opportunistic infections improves in a situation of continued high disease prevalence in Africa.

    Objective Inflammation and infection within the central nervous system is initiated during primary HIV infection (PHI), but the association of these processes with the integrity of brain white matter during PHI is unknown. Design We used diffusion tensor imaging (DTI) in this prospective cross-sectional neuroimaging study to determine the extent of white matter involvement in early HIV infection. Methods Antiretroviral-naive PHI (defined as <1 year after infection, n = 62), chronic HIV infection (CHI, n = 16), and HIV-uninfected (n = 19) participants had DTI, laboratory, and neuropsychometric performance assessments. DTI metrics were examined using region of interest and whole brain voxelwise analyses. Linear mixed-effects models assessed correlations between DTI measures and laboratory and neuropsychometric performance values. Results PHI participants were assessed at a median 4.1 months after estimated infection, and had median CD4+ cell count of 573 cells/µl, and HIV-1 RNA viral load of 4.5 log10 copies/ml in plasma and 2.6 log10 copies/ml in cerebrospinal fluid (CSF). DTI metrics in PHI individuals were similar to HIV— participants and correlated with disruptions in the blood-brain barrier (indicated by CSF/plasma albumin ratio and CSF protein). CHI participants had significant loss of white matter integrity that correlated with biomarkers of infection and inflammation (blood viral load, CD4+ T-cell count, and neopterin, and CSF white blood cell). Within the PHI group, DTI metrics inversely correlated with increasing days since infection. Conclusion In individuals assessed during PHI, group DTI measures suggested relative preservation of white matter microstructural integrity, but were associated with disruption of the blood-brain barrier and estimated duration of infection.

    Human commensal bacteria do not normally cause any diseases. However, in certain pathological conditions, they exhibit a number of curious behaviors. In HIV infection, these bacteria exhibit bidirectional relationships: whereas they cause opportunistic infections based on immunological deterioration, they also augment HIV replication, in particular, viral replication from latently infected cells, which is attributable to the effect of butyric acid produced by certain anaerobic bacteria by modifying the state of chromatin. Here, we review recent evidence supporting the contributory role of such endogenous microbes in disrupting HIV latency and its potential link to the clinical progression of AIDS. PMID:23616411

    2013-01-01

    Background Data on sexually transmitted infections (STI) prevalence among HIV-infected women in Thailand are limited. We studied, among HIV-infected women, prevalence of STI symptoms and signs; prevalence and correlates of having any STI; prevalence and correlates of Chlamydia trachomatis (CT) or Neisseria gonorrhoeae (GC) among women without CT and/or GC symptoms or signs; and number of women without CT and/or GC symptoms or signs needed to screen (NNS) to detect one woman with CT and/or GC overall, among pregnant women, and among women ≤25 years. Methods During October 2004–September 2006, HIV-infected women at 3 obstetrics and gynecology clinics were asked about sexual behaviors and STI symptoms, physically examined, and screened for chlamydia, gonorrhea, trichomoniasis, and syphilis. Multivariate logistic regression was used to identify correlates of infections. NNS was calculated using standard methods. Results Among 1,124 women, 526 (47.0%) had STI symptoms or signs, 469 (41.7%) had CT and/or GC symptoms or signs, and 133 (11.8%) had an STI. Correlates of having an STI included pregnancy and having STI signs. Among 469 women and 655 women with vs. without CT and/or GC symptoms or signs, respectively, 43 (9.2%) vs. 31 (4.7%), 2 (0.4%) vs. 9 (1.4%), and 45 (9.6%) vs. 38 (5.8%) had CT, GC, or “CT or GC”, respectively; correlates included receiving care at university hospitals and having sex with a casual partner within 3 months. NNS for women overall and women ≤25 years old were 18 (95% CI, 13-25) and 11 (95% CI, 6-23), respectively; and for pregnant and non-pregnant women, 8 (95% CI, 4-24) and 19 (95% CI, 14-27), respectively. Conclusions STI prevalence among HIV-infected women, including CT and GC among those without symptoms or signs, was substantial. Screening for CT and GC, particularly for pregnant women, should be considered. PMID:23601556

    HIV infection, and potentially its treatment, increases the risk of an arterial ischemic stroke. Multiple etiologies and lack of clear case definitions inhibit progress in this field. Several etiologies, many treatable, are relevant to HIV-related stroke. To fully understand the mechanisms and the terminology used, a robust classification algorithm to help ascribe the various etiologies is needed. This consensus paper considers the strengths and limitations of current case definitions in the context of HIV infection. The case definitions for the major etiologies in HIV-related strokes were refined (e.g., varicella zoster vasculopathy and antiphospholipid syndrome) and in some instances new case definitions were described (e.g., HIV-associated vasculopathy). These case definitions provided a framework for an algorithm to help assign a final diagnosis, and help classify the subtypes of HIV etiology in ischemic stroke. PMID:27386505

    Diagnosing asymptomatic neurosyphilis (ANS) in HIV-infected patients is difficult. A recent report suggested that CXCL13 is a promising diagnostic marker for neurosyphilis in HIV-positive patients. However, whether CXCL13 can be a diagnostic marker for ANS in HIV-infected patients remains unknown. The purpose of our study was to determine the role of CXCL13 in diagnosing ANS in HIV-infected patients. This study comprised two study and three control groups. Two study groups included 12 HIV-infected patients with ANS and 25 patients with syphilis and HIV co-infection (without ANS). Three control groups included 9 patients with ANS without HIV infection, 25 HIV-infected patients without syphilis and 10 healthy volunteers. Concentrations of CSF CXCL13 were measured before and after neurosyphilis therapy. Our results showed that CSF CXCL13 concentrations were significantly increased in all of the HIV-infected patients with ANS, the 25 HIV patients with syphilis and the 9 ANS patients without HIV, but not in the patients of the other two control groups. CSF CXCL13 concentrations declined in the two study groups of patients following neurosyphilis therapy. Therefore, CSF CXCL13 concentrations could improve the diagnosis of ANS in HIV-infected patients. PMID:25769888

    Objective To incorporate preexposure prophylaxis (PrEP) and other biomedical or intensive behavioral interventions into the care of injection drug users, healthcare providers need validated, rapid, risk screening tools for identifying persons at highest risk of incident HIV infection. Methods To develop and validate a brief screening tool for assessing the risk of contracting HIV (ARCH), we included behavioral and HIV test data from 1904 initially HIV-uninfected men and women enrolled and followed in the ALIVE prospective cohort study between 1988 and 2008. Using logistic regression analyses with generalized estimating equations (GEE), we identified significant predictors of incident HIV infection, then rescaled and summed their regression coefficients to create a risk score. Results The final logistic regression model included age, engagement in a methadone maintenance program, and a composite injection risk score obtained by counting the number of the following five behaviors reported during the past six months: injection of heroin, injection of cocaine, sharing a cooker, sharing needles, or visiting a shooting gallery. The area under the receiver operating characteristic curve was 0.720, possible scores on index ranged from 0 to 100 and a score ≥46 had a sensitivity of 86.2% and a specificity of 42.5%, appropriate for a screening tool. Discussion We developed an easy to administer 7-question screening tool with a cutoff that is predictive of incident HIV infection in a large prospective cohort of injection drug users in Baltimore. The ARCH-IDU screening tool can be used to prioritize persons who are injecting illicit drugs for consideration of PrEP and other intensive HIV prevention efforts. PMID:25961495

    Background Major depressive disorder is highly prevalent among HIV-infected persons, and depression symptom severity improves during the course of HIV antiretroviral therapy (ART). The potential biologic pathways explaining these phenomena remain unclear. We investigated the extent to which ART-mediated suppression of the kynurenine pathway of tryptophan catabolism (via indoleamine 2,3-dioxygenase-1 and potentially other sources) may correlate with improvements in depression symptom severity in this setting. Method We used the first year of data from the Uganda AIDS Rural Treatment Outcomes Study, a prospective cohort of 504 HIV-infected individuals initiating their first ART regimen in rural Uganda. We fitted random-effects regression models to estimate the associations between plasma tryptophan, plasma kynurenine, dietary diversity, and self-reported depression symptom severity. Results Greater depressive symptoms were associated with both lower plasma tryptophan and higher plasma kynurenine/tryptophan (KT) ratio over 12-month follow-up. In multivariable-adjusted models, declines in KT ratio and increases in plasma tryptophan levels partially explained ART-mediated improvements in depressive symptom severity. The association between KT ratio and depression symptom severity was stronger among persons with protein-deficient diets than among those with protein-rich diets. Conclusions IDO-mediated tryptophan catabolism may contribute to depression symptom severity among HIV-infected individuals, particularly among those with poor dietary protein intake. ART-mediated improvements in depressive symptom severity may also be at least partially mediated by immunologic mechanisms. Interventions to reduce immune activation, and dietary protein supplementation, may be promising strategies to further reduce depression in this setting. PMID:24220289

    Background High retention rates have been documented among patients receiving antiretroviral therapy (ART) in Myanmar. However, there is no information on human immunodeficiency virus (HIV)-infected individuals in care before initiation of ART (pre-ART care). We assessed attrition (loss-to-follow-up [LTFU] and death) rates among HIV-infected individuals in pre-ART care and their associated factors over a 4-year period. Design In this retrospective cohort study, we extracted routinely collected data of HIV-infected adults (>15 years old) entering pre-ART care (June 2011–June 2014) as part of an Integrated HIV Care (IHC) programme, Myanmar. Attrition rates per 100 person-years and cumulative incidence of attrition were calculated. Factors associated with attrition were examined by calculating hazard ratios (HRs). Results Of 18,037 HIV-infected adults enrolled in the IHC programme, 11,464 (63%) entered pre-ART care (60% men, mean age 37 years, median cluster of differentiation 4 (CD4) cell count 160 cells/µL). Of the 11,464 eligible participants, 3,712 (32%) underwent attrition of which 43% were due to deaths and 57% were due to LTFU. The attrition rate was 78 per 100 person-years (95% CI, 75–80). The cumulative incidence of attrition was 70% at the end of a 4-year follow-up, of which nearly 90% occurred in the first 6 months. Male sex (HR 1.5, 95% CI 1.4–1.6), WHO clinical Stage 3 and 4, CD4 count <200 cells/µL, abnormal BMI, and anaemia were statistically significant predictors of attrition. Conclusions Pre-ART care attrition among persons living with HIV in Myanmar was alarmingly high – with most attrition occurring within the first 6 months. Strategies aimed at improving early HIV diagnosis and initiation of ART are needed. Suggestions include comprehensive nutrition support and intensified monitoring to prevent pre-ART care attrition by tracking patients who do not return for pre-ART care appointments. It is high time that Myanmar moves towards a

    Context Antiretroviral therapy has been associated with hypercholesterolemia in HIV-infected children. Few longitudinal studies have been conducted to examine this association, however. Objective To evaluate the incidence of and risk factors for development of hypercholesterolemia in a large pediatric study. Design Prospective cohort study (Pediatric AIDS Clinical Trials Group 219C). Participants A total of 2122 perinatally HIV-infected children free of hypercholesterolemia at entry. Outcome Development of hypercholesterolemia (total cholesterol ≥220 mg/dL at 2 consecutive visits). Cox proportional hazards models were used to evaluate risk factors. Results Thirteen percent of children had hypercholesterolemia at entry, and an additional 13% developed hypercholesterolemia during follow-up for an incidence rate of 3.4 cases per 100 person-years (95% confidence interval [CI]: 3.0 to 3.9). After adjustment for age, boosted protease inhibitor (PI) use (hazard ratio [HR] = 13.9, 95% CI: 6.73 to 28.6), nonboosted PI use (HR = 8.65, 95% CI: 4.19 to 17.9), and nonnucleoside reverse transcriptase inhibitor use (HR = 1.33, 95% CI: 1.04 to 1.71) were associated with increased risk of hypercholesterolemia, and higher viral load was protective (>50,000 vs. ≤400 copies/mL; HR = 0.59, 95% CI: 0.39 to 0.90). Self-reported adherent subjects had higher risk. Conclusions PIs were significant risk factors for hypercholesterolemia. Higher viral load was protective and may reflect non-adherence. Further follow-up is critical to evaluate long-term consequences of chronic PI exposure and hypercholesterolemia. PMID:18209684

    The Office of Minority Health (OMH) was established in December 1985 in response to recommendations developed by the Secretary's Task Force on Black and Minority Health. Originally, OMH's mission emphasized six health problems identified by the Task Force as priority areas: cancer, cardiovascular disease and stroke; chemical dependency; diabetes; homicide, suicide, and unintentional injuries; and infant mortality and low birth weight. OMH added HIV infection to the six health priority areas after epidemiologic data showed that the representation of blacks and Hispanics was disproportionately high among persons reported with AIDS. Strategies to eliminate or reduce high-risk behaviors associated with HIV infection need to mobilize racial and ethnic minority communities and rebuild social networks in order to foster sustained behavioral changes. OMH created the Minority HIV Education/Prevention Grant Program to demonstrate the effectiveness of strategies to expand the activities of minority community-based and national organizations involved in HIV education and prevention, as well as to encourage innovative approaches to address appropriately the diversities within and among minority populations. In 1988, grants totaling $1.4 million were awarded to four national and 23 community-based minority organizations. Project workers conduct information, education, and prevention interventions directed to specific groups within racial and ethnic minority communities. Interventions include education and prevention training, information activities, developing educational materials, and providing technical assistance. Project innovations include conducting HIV education and prevention training for families at home, presenting a play produced and performed by local teenagers, and developing a workshop and a manual to help minority service organizations to recruit and train volunteer staff members.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:2511587

    Interviews regarding medical history, life-style, specific drug taking and sexual activities, and physical examinations were administered to 4,955 homosexual men who volunteered for the Multicenter AIDS Cohort Study in Baltimore, Chicago, Los Angeles, and Pittsburgh. Overall, the prevalence of antibodies to human immunodeficiency virus (HIV) in these men was 38.0%. The factor most strongly associated with prevalent HIV infection according to a multiple logistic regression model was rectal trauma, a composite variable which included receptive anal fisting, enemas before sex, reporting of blood around the rectum, and the observation of scarring, fissures or fistulas on rectal examination. Receptive anal intercourse also was strongly associated with HIV infection in the model. The multivariate relative odds for HIV antibody positivity was 7.72 for the highest level of rectal trauma and 3.04 for receptive anal intercourse. Symptoms reported to occur in some persons who subsequently develop acquired immunodeficiency syndrome (AIDS) were frequent among HIV seropositive men (12.9%) but were reported in 8.4% of seronegative men as well. Generalized lymphadenopathy was observed significantly more often in seropositive men (48.8%) compared with seronegative men (11.4%). The prevalence of HIV antibodies was inversely related to the number of T-helper cells and directly related (to a lesser extent) to the number of T-suppressor cells. The results suggest that disruption of the rectal mucosa provides access by HIV to the blood stream and to specific immunologic cells. Since symptoms and generalized lymphadenopathy were often reported among seronegative men, they probably also occur among some seropositive men not currently progressing to AIDS. PMID:3651095

    Background: Host genetic factors may a play role in susceptibility to infection. Vitamin-D is an immunomodulator that may play a role in HIV infection. Vitamin-D action is mediated by the vitamin-D receptor. We establish prevalence of ApaI, BsmI, FokI and TaqI polymorphisms (VDRPs) amongst a black southern African HIV+ve population and investigate polymorphic differences between HIV+ve and -ve people. Methods: Seventy-nine sex and age-group matched HIV+ve patients of African origin initiating antiretroviral therapy (ART) and 79 HIV-ve participants, also of African origin, were recruited from a public sector HIV testing and treatment clinic and investigated for the 4 polymorphisms. The genotype frequencies were compared, odds ratios and 95% confidence intervals of the association of HIV status and each genotype were calculated. Both dominant, co-dominant, recessive and allele models were tested. Results: We found no evidence of difference in distribution and association between HIV infection and the genotypes of the BsmI, FokI and TaqI VDR polymorphisms. The genotype distributions were consistent with Hardy-Weinberg equilibrium for these genotypes. The ApaI genotype showed differences in distribution by HIV status in the dominant and co-dominant models. However this finding is cautiously stated as the ApaI genotype violated the Hardy-Weinberg equilibrium and frequency of the minor variant was unexpectedly low in this population. Conclusion: We do not show convincing differences in distribution of the VDR genotypes among HIV+ve and HIV-ve black southern African persons. Future studies need to be replicated in larger study populations as understanding polymorphic differences and similarities may offer insights into the different susceptibility and progression of HIV in southern African populations.

    Objective: In Iran, psychological aspect of HIV infection is poorly understood. The purposes of this study were to evaluate sexual dysfunction, depression rate and health-related quality of life and evaluate the association between sexual dysfunction, depression and quality of life in a group of HIV+ subjects in Shiraz, Iran. Methods: In this cross-sectional study, 278 male HIV-positive patients who had referred to voluntary counseling and testing and methadone maintenance therapy centers were recruited based on convenience sampling from May to October 2010. The purpose of the study was explained and interested individuals provided informed consent and completed validated questionnaires [Medical Outcomes Study Short Form-36 (SF-36(, Brief Male Sexual Function Inventory (BMSFI), Beck Depression Inventory-short form(BDI)] to assess overall health related quality of life (HRQOL), sexual function, and depression. Results: Average age of the participants was 34.9 ± 10.7 years and 37.5% were severely depressed. Ordinal logistic regression indicated that sexual drive (-0.15; CI: -0.28 to -0.027), ejaculation (-1.91, CI: -2.71 to -1.12), and problem assessment (-0.098, CI: -0.17 to -0.02) had significant effect on depression type. Depression was significantly correlated with poorer quality of life in all domains. Pearson’s correlation coefficients between the BMSFI and the domains of SF-36 indicated that sexual drive (r= 0.215), ejaculation (r= 0.297) and problem assessment (r= 0.213) were significantly correlated with emotional wellbeing. Conclusion: Sexual function and depression showed association with quality of life. Effective treatment of depression and sexual function may improve the quality of life of HIV-infected person.

    HIV infection is associated with depletion of CD4(+) T cells. The mechanisms of this phenomenon remain to be understood. In particular, it remains controversial whether and to what extent uninfected ("bystander") CD4(+) T cells die in HIV-infected individuals. We address this question using a system of human lymphoid tissue ex vivo. Tissue blocks were inoculated with HIV-1. After productive infection was established, they were treated with the reverse transcriptase inhibitor nevirapine to protect from infection those CD4(+) T cells that had not yet been infected. These CD4(+) T cells residing in HIV-infected tissue are by definition bystanders. Our results demonstrate that after nevirapine application the number of bystander CD4(+) T cells is conserved. Thus, in the context of HIV-infected human lymphoid tissue, productive HIV infection kills infected cells but is not sufficient to cause the death of a significant number of uninfected CD4(+) T cells.

    Problem Effects of HIV infection on ovarian function and aging are unclear. Method of Study Anti-Müllerian Hormone (AMH) levels were analyzed in 2621 HIV-infected and 941 uninfected participants using left-censored longitudinal models. Results Age-adjusted AMH levels were 16% lower in women with undetectable viremia and 26% lower in detectable viremia, relative to uninfected women. Current CD4 count associated with higher AMH in both HIV-infected and HIV-uninfected women. After controlling for current and nadir CD4, AMH was ~15% higher in HIV-infected relative to uninfected women, regardless of HIV viremia. Gravidity, amenorrhea, and nadir total lymphocyte counts associated with higher AMH; hormonal contraceptive use and past weight loss associated with lower AMH. Conclusions CD4+ lymphocyte counts were associated with AMH in both HIV-infected and uninfected women. After adjustment for CD4 counts and age, HIV infection was associated with higher AMH. CD4 T cells and cellular activation may influence ovarian granulosa cell function. PMID:25339186

    Hodgkin lymphoma (HL) presenting in patients with co-incidental advanced age, pregnancy, or human immunodeficiency virus (HIV) infection is uniquely challenging to manage. In this article we integrate recent evidence and clinical expertise to present recommendations for diagnosis and therapeutic management. Older patients with HL need to be carefully evaluated for comorbidies after which judicious choice of chemotherapy should minimize functional compromise. A pregnant patient with concurrent HL should be staged with minimal use of imaging requiring ionizing radiation and treated in an individualized manner optimally combining the strategies of treatment deferral when appropriate, use of single-agent vinblastine for symptomatic disease and reservation of multi-agent chemotherapy for the small minority of patients with aggressive clinical presentation. Treatment of HL coincident with HIV infection requires a combination of highly active anti-retroviral agents (HAART), standard multi-agent chemotherapy with meticulous attention to drug-drug interactions, and vigorous supportive care to ensure the best chance of cure.

    On 3 previous occasions, in 2002, 2003 and 2005, the Swedish Medical Products Agency (Läkemedelsverket) and the Swedish Reference Group for Antiviral Therapy (RAV) have jointly published recommendations for the treatment of HIV infection. An expert group, under the guidance of RAV, has now revised the text again. Since the publication of the previous treatment recommendations, 1 new drug for the treatment of HIV has been approved - the protease inhibitor (PI) darunavir (Prezista). Furthermore, 3 new drugs have become available: the integrase inhibitor raltegravir (MK-0518), the CCR5-inhibitor maraviroc (Celsentri), both of which have novel mechanisms of action, and the non-nucleoside reverse transcriptase inhibitor (NNRTI) etravirine (TMC-125). The new guidelines differ from the previous ones in several respects. The most important of these are that abacavir is now preferred to tenofovir and zidovudine, as a first line drug in treatment-naïve patients, and that initiation of antiretroviral treatment is now recommended before the CD4 cell count falls below 250/microl, rather than 200/microl. Furthermore, recommendations on the treatment of HIV infection in children have been added to the document. As in the case of the previous publication, recommendations are evidence-graded in accordance with the Oxford Centre for Evidence Based Medicine, 2001 (see http://www.cebm.net/levels_of_evidence.asp#levels).

    Infection by the human immunodeficiency virus (HIV) causes a multi-faceted disease process which ultimately leads to severe degenerative conditions in the immune and nervous systems. The complexity of the virus/host-system interaction has brought into sharp focus the need for alternative efforts by which to overcome the limitations of available animal models. This article reports on the dynamics of HIV infection in an artificial immune system (AIS), a novel in silico tool for bio-medical research. Using a method of graphical programming, the HIV/AIS interactions are described at the cellular level and then transferred into the setting of an asynchronous cellular automaton simulation. A specific problem in HIV pathogenesis is addressed: To determine the extent by which the physiological connectivity of a normal B-cell, T-cell, macrophage immune system supports persistence of infection and disease progression to AIDS. Several observations are discussed which will be presented in four categories: (a) the major known manifestations of HIV infection and AIDS; (b) the predictability of latency and sudden progression to disease; (c) the predictability of HIV-dependent alterations of cytokine secretion patterns, and (d) secondary infections, which are found to be a critical element in establishing and maintaining a progressive disease dynamics. The effects of exogenously applied cytokine Interleukin 2 are considered. All results are summarized in a phase-graph model of the global HIV/AIS dynamical system.

    Purpose Little is known about the association of intimate partner violence (IPV) with specific HIV treatment outcomes, especially among criminal justice (CJ) populations who are disproportionately affected by IPV, HIV, mental and substance use disorders (SUDs) and are at high risk of poor post-release continuity of care. Design/Methodology/Approach Mixed methods were used to describe the prevalence, severity, and correlates of lifetime IPV exposure among HIV-infected jail detainees enrolled in a novel jail-release demonstration project in Connecticut. Additionally, the effect of IPV on HIV treatment outcomes and longitudinal healthcare utilization was examined. Findings Structured baseline surveys defined 49% of 84 participants as having significant IPV-exposure, which was associated with female gender, longer duration since HIV diagnosis, suicidal ideation, having higher alcohol use severity, having experienced other forms of childhood and adulthood abuse, and homo/bisexual orientation. IPV was not directly correlated with HIV healthcare utilization or treatment outcomes. In-depth qualitative interviews with 20 surveyed participants, however, confirmed that IPV was associated with disengagement from HIV care especially in the context of overlapping vulnerabilities, including transitioning from CJ to community settings, having untreated mental disorders, and actively using drugs or alcohol at the time of incarceration. Value Post-release interventions for HIV-infected CJ populations should minimally integrate HIV secondary prevention with violence reduction and treatment for SUDs. PMID:24376468

    OBJECTIVES: This study sought to identify predictors of dental care use in HIV-infected women. METHODS: In a cross-sectional survey of HIV-infected women enrolled in the northern California site of the Women's Interagency HIV Study, dental care use and unmet need were assessed in relation to selected variables. RESULTS: Among 213 respondents, who were predominantly Black and younger than 45 years, 43% had not seen a dentist and 53% (among dentate women) reported no dental cleaning in more than a year (although 67% had dental insurance coverage, mainly state Medicaid). Nine percent were edentulous. Among nonusers of dental care, 78% reported that they wanted care but failed to get it. Barriers included fear of and discomfort with dentists, not getting around to making an appointment, and not knowing which dentist to visit. Multivariate analysis showed that lack of past-year dental care was associated mainly with unemployment, a perception of poor oral health, and edentulism. CONCLUSIONS: HIV-positive women appear to be underusing dental care services. Fear and lack of information regarding available resources, in addition to unemployment and perception of poor oral health, may be important barriers. PMID:10358671

    An investigation was conducted to study the robustness of the results obtained from the cellular automata model which describes the spread of the HIV infection within lymphoid tissues [R.M. Zorzenon dos Santos, S. Coutinho, Phys. Rev. Lett. 87 (2001) 168102]. The analysis focused on the dynamic behavior of the model when defined in lattices with different symmetries and dimensionalities. The results illustrated that the three-phase dynamics of the planar models suffered minor changes in relation to lattice symmetry variations and, while differences were observed regarding dimensionality changes, qualitative behavior was preserved. A further investigation was conducted into primary infection and sensitiveness of the latency period to variations of the model’s stochastic parameters over wide ranging values. The variables characterizing primary infection and the latency period exhibited power-law behavior when the stochastic parameters varied over a few orders of magnitude. The power-law exponents were approximately the same when lattice symmetry varied, but there was a significant variation when dimensionality changed from two to three. The dynamics of the three-dimensional model was also shown to be insensitive to variations of the deterministic parameters related to cell resistance to the infection, and the necessary time lag to mount the specific immune response to HIV variants. The robustness of the model demonstrated in this work reinforce that its basic hypothesis are consistent with the three-stage dynamic of the HIV infection observed in patients.

    Viral lesions of the mouth in patients with HIV infection are common and these diseases any be a marker for HIV and disease progression. We review the spectrum of oral viral manifestations and discuss treatment modalities. The most common Epstein-Barr virus (EBV)-induced disorder in HIV-infected patients is oral hairy leukoplakia. EBV-related oral B-cell and T-cell lymphoma in AIDS patients has been described repeatedly. Herpes virus type 1 and rarely type 2 may lead to painful and resistant oral ulcers, and systemic treatment with acyclovir, valaciclovir or famciclovir is indicated. In acyclovir-resistant cases foscarnet is the treatment of choice. In recent years it has been documented that Kaposi's sarcoma, which often affects oral mucosa, is probably induced by herpesvirus type 8. Cytomegalovirus was found in 53% of cases with herpesviridae-induced mucosal ulcers as the only ulcerogenic viral agent in AIDS patients. In severe cytomegalovirus infection treatment with ganciclovir is helpful. Viral warts induced by different HPV may occur in the mouth. Several physical treatment modalities are possible in the oral mucosa. In AIDS patients mollusca contagiosa may occur as large and atypical lesions in the face and lips and rarely in the oral cavity. Cryotherapy is a bloodless treatment in such patients. PMID:9031782

    An emerging literature indicates that HIV infection is associated with deficits in prospective memory (ProM), or the ability to execute a future intention. This literature offers evidence of neurobiological dissociability of ProM from other cognitive abilities and its incremental ecological validity as a predictor of poorer everyday functioning outcomes (e.g., medication non-adherence). The present study evaluated the hypothesis that ProM represents a unique cognitive construct in HIV disease. A confirmatory 4-factor structural equation model was tested on data derived from 162 participants with HIV. The model posited that measures of ProM comprise a unique factor, apart from standard clinical tests of retrospective memory, executive functions, and motor skills. The fit of the model was evaluated using the Bollen-Stine bootstrap method and indicated a 4-factor model with measures of ProM loading on a unique factor fit the data well, and better than a model with a single common factor hypothesized to drive cognitive performance. The results of this study lend further evidence to the dissociability of ProM in HIV infection, are consistent with prior studies in healthy adults, and contribute to a growing literature on the construct validity of ProM in HIV disease.

    Caveolin 1 (Cav-1) is a major protein of a specific membrane lipid raft known as caveolae. Cav-1 interacts with the gp41 of the human immunodeficiency virus (HIV) envelope, but the role of Cav-1 in HIV replication and pathogenesis is not known. In this report, we demonstrate that HIV infection in primary human monocyte-derived macrophages (MDMs), THP-1 macrophages, and U87-CD4 cells results in a dramatic upregulation of Cav-1 expression mediated by HIV Tat. The activity of p53 is essential for Tat-induced Cav-1 expression, as our findings show enhanced phosphorylation of serine residues at amino acid positions 15 and 46 in the presence of Tat with a resulting Cav-1 upregulation. Furthermore, inhibition of p38 mitogen-activated protein kinase (MAPK) blocked phosphorylation of p53 in the presence of Tat. Infection studies of Cav-1-overexpressing cells reveal a significant reduction of HIV production. Taken together, these results suggest that HIV infection enhances the expression of Cav-1, which subsequently causes virus reduction, suggesting that Cav-1 may contribute to persistent infection in macrophages.

    Objective As women with HIV are living longer, more are entering the perimenopause. Prior studies suggest that HIV-infected women are more likely to have hot flashes than non-HIV-infected women. However, little is known regarding the severity and degree of interference that hot flashes have on daily function, mood, and quality of life in this population. Methods Perimenopausal HIV-infected and non-HIV-infected women matched by age, race, and menstrual patterns completed the Menopause Rating Scale (MRS) to assess hot flash severity and the Hot Flash Related Daily Interference Scale (HFRDIS). MRS and HFRDIS scores and subscores were compared between groups. Results 33 HIV-infected and 33 non-HIV-infected women similar in age (47 (45,48) median (interquartile range) vs. 47 (46,49) yrs; race (64% vs. 52% non-white; P=0.32), and menstrual patterns (# periods in past year; 5 (4,9) vs. 6 (4,10); P=0.53) were studied. Perimenopausal HIV-infected women reported greater hot flash severity (HIV; 2 (1,3) vs. non-HIV: 1 (0,3); P=0.03), and hot flash-related interference (HFRDIS total score; 37 (10,60) vs. 6 (0,20); P=0.001). Conclusions Perimenopausal HIV-infected women experience greater hot flash severity and related interference compared to non-HIV-infected perimenopausal women. Increased distress secondary to hot flashes may reduce quality of life and negatively impact important health-promoting behaviors including adherence to antiretroviral therapy in HIV-infected women.

    Abstract HIV-infected individuals leaving jails, facilities typically used to confine accused persons awaiting trial or to incarcerate persons for minor offenses, often face barriers to engagement with medical and social-support services. Patient navigation is a model that may ease these barriers by supporting individuals in negotiating fragmented and highly bureaucratic systems for services and care. While there is evidence linking navigation to a reduction in health disparities, little is known about the mechanisms by which the model works. We present findings of an ethnographic study of interactions between navigators and their clients: HIV-infected men and women recently released from jails in San Francisco, California. We conducted 29 field observations of navigators as they accompanied their clients to appointments, and 40 in-depth interviews with clients and navigators. Navigators worked on strengthening clients' abilities to engage with social-services and care systems. Building this strength required navigators to gain clients' trust by leveraging their own similar life experiences or expressing social concordance. After establishing meaningful connections, navigators spent time with clients in their day-to-day environments serving as mentors while escorting clients to and through their appointments. Intensive time spent together, in combination with a shared background of incarceration, HIV, and drug use, was a critical mechanism of this model. This study illustrates that socially concordant navigators are well positioned to facilitate successful transition to care and social-services engagement among a vulnerable population. PMID:24517539

  1. Management of Lipid Levels and Cardiovascular Disease in HIV-Infected Individuals: Just Give Them a Statin?

    PubMed

    Stein, James H

    Current guidelines for managing cholesterol to reduce cardiovascular disease (CVD) risk focus on providing the appropriate intensity of statin therapy to reduce low-density lipoprotein cholesterol (LDL-C) level. There is very little evidence supporting the use of treatments aimed at raising high-density lipoprotein cholesterol level or reducing triglyceride levels. HIV-infected persons have excess risk of CVD compared with the general population. Statins are less effective at reducing LDL-C levels in HIV-infected persons who are also at greater risk for adverse effects from statin treatment. When selecting a statin to achieve desired lowering of LDL-C level, the potential for drug interactions with antiretroviral therapy must be considered. Information from ongoing research is expected to help identify optimal strategies for use of statin treatment in this population. This article summarizes a presentation by James H. Stein, MD, at the IAS-USA continuing education program, Improving the Management of HIV Disease, held in Chicago, Illinois, in May 201. PMID:27398770

    Objective Inflammatory biomarkers associated with cardiovascular disease are elevated in HIV-infected persons. These biomarkers improve with antiretroviral therapy (ART) but do not normalize to values observed in HIV-uninfected adults. Little is known regarding biomarkers of inflammation in HIV-infected Peruvians, in whom an increased burden of infectious diseases may exacerbate inflammation, and women, in whom sex difference may alter inflammation compared with men. Methods Peruvians initiating first-line ART were enrolled in a prospective observational study. Individuals with suppression of HIV RNA plasma loads to less than 30 copies/ml when determined quarterly over 24 months of ART, had biomarkers of inflammation and cellular activation measured pre-ART and at 24-months of ART, and evaluated for associations with sex and clinical parameters. Results Pre-ART high-sensitivity C-reactive protein (hsCRP) values of men were in the high-risk cardiovascular disease category (>3.0mg/l) more frequently compared with women (P = 0.02); most women’s values were in the low/average-risk categories. At 24 months of suppressive ART, hsCRP concentrations decreased in men (P = 0.03), but tended to increase in women, such that the proportion with high-risk hsCRP did not differ by sex. Pre-ART, soluble CD163 concentrations were higher in women compared with men (P = 0.02), and remained higher after 24 months of suppressive ART (P = 0.02). All other inflammatory biomarkers (P < 0.03) decreased across sexes. Biomarker concentrations were not associated with BMI or coinfections. Conclusion Elevated inflammatory biomarkers persisted despite 24 months of suppressive ART in a subset of Peruvians, and to a greater extent in women compared with men. These findings suggest that lifestyle or pharmacologic interventions may be required to optimize the health of HIV-infected Peruvians, particularly women. PMID:26372272

    Over half of HIV infections in the United States occur among men who have sex with men (MSM). Awareness of infection is a necessary precursor to antiretroviral treatment and risk reduction among HIV-infected persons. We report data on prevalence and awareness of HIV infection among MSM in 2008 and 2011, using data from 20 cities participating in the 2008 and 2011 National HIV Behavioral Surveillance System (NHBS) among MSM. Venue-based, time-space sampling was used to recruit men for interview and HIV testing. We analyzed data for men who reported ≥ 1 male sex partner in the past 12 months. Participants who tested positive were considered to be aware of their infection if they reported a prior positive HIV test. We used multivariable analysis to examine differences between results from 2011 vs. 2008. HIV prevalence was 19% in 2008 and 18% in 2011 (p = 0.14). In both years, HIV prevalence was highest among older age groups, blacks, and men with lower education and income. In multivariable analysis, HIV prevalence did not change significantly from 2008 to 2011 overall (p = 0.51) or in any age or racial/ethnic category (p>0.15 in each category). Among those testing positive, a greater proportion was aware of their infection in 2011 (66%) than in 2008 (56%) (p<0.001). In both years, HIV awareness was higher for older age groups, whites, and men with higher education and income. In multivariable analysis, HIV awareness increased from 2008 to 2011 overall (p<0.001) and for all age and racial/ethnic categories (p<0.01 in each category). In both years, black MSM had the highest HIV prevalence and the lowest awareness among racial/ethnic groups. These findings suggest that HIV-positive MSM are increasingly aware of their infections.

    Objective HIV-infected (HIV+) individuals may have differential risk of diabetes mellitus (DM) compared to the general population, and the optimal diagnostic algorithm for DM in HIV+ persons remains unclear. We aimed to assess the utility of oral glucose tolerance testing (OGTT) for DM diagnosis in a cohort of women with or at risk for HIV infection. Methods Using American Diabetic Association DM definitions, DM prevalence and incidence were assessed among women enrolled in the Women’s Interagency HIV Study. DM was defined by 2-hour OGTT ≥ 200 mg/dL (DM_OGTT) or a clinical definition (DM_C) that included any of the following: (i) anti-diabetic medication use or self-reported DM confirmed by either fasting glucose (FG) ≥126 mg/dL or HbA1c ≥ 6.5%, (ii) FG ≥ 126 mg/dL confirmed by a second FG ≥ 126 mg/dL or HbA1c 6.5%, or (iii) HbA1c 6.5% confirmed by FG ≥ 126 mg/dL cohort. Results Overall, 390 women (285 HIV+, median age 43 years; 105 HIV−, median age 37 years) were enrolled between 2003-2006. Over half of all women were African American. Using DM_C, DM prevalence rates were 5.6% and 2.8% among HIV+ and HIV− women, respectively. Among HIV+ women, adding DM_OGTT to DM_C increased DM prevalence from 5.6% to 7.4%, a 31% increase in the number of diabetes cases diagnosed (p=0.02). In HIV− women, no additional cases were diagnosed by DM-OGTT. Conclusion In HIV+ women, OGTT identified DM cases that were not identified by a standardized clinical definition. Further investigation is needed to determine whether OGTT should be considered as an adjunctive tool for DM diagnosis in the setting of HIV infection. PMID:27066296

  5. HIV infection among heterosexuals at increased risk--United States, 2010.

    PubMed

    2013-03-15

    In 2009, an estimated 27% of human immunodeficiency virus (HIV) infections in the United States were attributed to heterosexual contact. During 2006-2007, as part of the data collection for the National HIV Behavioral Surveillance System (NHBS), CDC surveyed heterosexuals who lived in urban areas with a high prevalence of acquired immunodeficiency syndrome (AIDS) and found an overall HIV prevalence of 2.0% and a prevalence of 2.3% among persons with annual household incomes at or below the poverty level and 2.8% among persons with less than a high school education. This report summarizes HIV testing results from the second cycle of NHBS, conducted in 2010, which focused on heterosexual persons with low socioeconomic status (SES) living in areas with high AIDS case rates. The results indicated that HIV prevalence was 2.3% overall and 1.1% among participants who did not report a previous positive HIV test result. Overall, 25.8% of participants had never been tested for HIV until the NHBS survey. Given the high HIV prevalence in this sample, additional research should be conducted to identify culturally appropriate interventions that overcome barriers to HIV testing and increase linkage to care for heterosexuals with low SES in urban areas with high prevalence of AIDS.

    There has been a general recognition of a syndemic that includes HIV/AIDS and serve mental illnesses including schizophrenia, major depression, bipolar disorder, post-traumatic stress disorder, and others. The pathophysiology and direction of effects between severe mental illness and HIV infection is less clear however, and relatively little work has been done on prevention and treatment for people with these complex, co-occurring conditions. Here we present the most recent work that has been published on HIV and mental illness. Further, we describe the need for better treatments for "triply diagnosed persons"; those with HIV, mental illness, and substance abuse and dependence. Finally, we describe the potential drug-drug interactions between psychotropic medications and anti-retrovirals, and the need for better treatment guidelines in this area. We describe one example of an individually tailored intervention for persons with serious mental illness and HIV (PATH+) that shows that integrated community-based treatments using advanced practice nurses (APNs) as health navigators can be successful in improving health-related quality of life and reducing the burden of disease in these persons.

    Retaining subjects from disadvantaged populations in long-term studies is necessary to obtain high-quality data. This article presents cumulative retention rates from a 5-year prospective cohort study, the Pediatric Pulmonary and Cardiovascular Complications of Vertically Transmitted HIV Infection study. It also presents results of a cross-sectional qualitative survey about factors that induced caregivers to stay in the study. Although the repeated study visits were long and uncomfortable, cumulative retention among the 298 HIV-infected children was 80%. Incentives considered important by the caregivers included phone contact with nurse coordinators, nurse coordinators accompanying the caregiver and child during visits, phone reminders for appointments, help with scheduling, meals and transportation, access to health care, and relationships with staff. Thus, the high follow-up rate was in part due to nurses’ efforts to reduce the study’s burden on the families, provide tangible and intangible incentives, and establish personal relationships with families.

    The purpose of this study was to identify fecal bacterial microbiome changes in patients with chronic human immunodeficiency virus (HIV) infection in China. Bacterial 16S rRNA genes were amplified, sequenced (454 pyrosequencing), and clustered into operational taxonomic units using the QIIME software. Relative abundance at the phylum and genus levels were calculated. Alpha diversity was determined by Chao 1 and observed-species indices, and beta diversity was determined by double principal component analysis using the estimated phylogeny-based unweighted Unifrac distance matrices. Fecal samples of the patients with chronic HIV-infection tended to be enriched with bacteria of the phyla Firmicutes (47.20% ± 0.43 relative abundance) and Proteobacteria (37.21% ± 0.36) compared with those of the non-HIV infected controls (17.95% ± 0.06 and 3.81% ± 0.02, respectively). Members of the genus Bilophila were exclusively detected in samples of the non-HIV infected controls. Bacteroides and arabacteroides were more abundant in the chronic HIV-infected patients. Our study indicated that chronic HIV-infected patients in China have a fecal bacterial microbiome composition that is largely different from that found in non-HIV infected controls, and further study is needed to evaluate whether microbiome changes play a role in disease complications in the distal gut, including opportunistic infections.

    Objectives Non-AIDS-related malignancies now represent a frequent cause of death among HIV-infected patients. Albeit bladder cancer is one of the most common malignancies worldwide, it has been rarely reported among HIV-infected patients. We wished to assess the prevalence and characteristics of bladder cancer in HIV-infected patients. Methods We conducted a single center retrospective study from 1998 to 2013 in a university hospital in Paris. Cases of bladder cancer among HIV-infected patients were identified using the electronic records of the hospital database and of the HIV-infected cohort. Patient characteristics and outcomes were retrieved from patients charts. A systematic review of published cases of bladder cancers in patients with HIV-infection was also performed. Results During the study period we identified 15 HIV-infected patients (0.2% of the cohort) with a bladder cancer. Patients were mostly men (73%) and smokers (67%), with a median age of 56 years at cancer diagnosis. Bladder cancer was diagnosed a median of 14 years after HIV-infection. Most patients were on ART (86%) with median current and nadir CD4 cell counts of 506 and 195 cells/mm3, respectively. Haematuria (73%) was the most frequent presenting symptom and HPV-associated lesions were seen in 6/10 (60%) patients. Histopathology showed transitional cell carcinoma in 80% and a high proportion of tumors with muscle invasion (47%) and high histologic grade (73%). One-year survival rate was 74.6%. The systematic review identified 13 additional cases of urothelial bladder cancers which shared similar features. Conclusions Bladder cancers in HIV-infected patients remain rare but may occur in relatively young patients with a low nadir CD4 cell count, have aggressive pathological features and can be fatal.

    Objectives Although haematological abnormalities are common manifestations of HIV infection, few studies on haematological parameters in HIV-infected persons have been undertaken in sub-Saharan Africa. The authors assessed factors associated with haematological parameters in HIV-infected antiretroviral-naïve and HIV-uninfected Rwandan women. Study design Cross-sectional analysis of a longitudinal cohort. Setting Community-based women's associations. Participants 710 HIV-infected (HIV+) antiretroviral-naïve and 226 HIV-uninfected (HIV−) women from the Rwanda Women's Interassociation Study Assessment. Haematological parameters categorised as (abnormal vs normal) were compared by HIV status and among HIV+ women by CD4 count category using proportions. Multivariate logistic regression models using forward selection were fit. Results Prevalence of anaemia (haemoglobin (Hb) <12.0 g/dl) was higher in the HIV+ group (20.5% vs 6.3%; p<0.001), and increased with lower CD4 counts: ≥350 (7.6%), 200–349 (16%) and <200 cells/mm3 (32.2%). Marked anaemia (Hb <10.0 g/dl) was found in 4.2% of HIV+ and none of the HIV− women (p<0.001), and was highest in HIV+ women with CD4 <200 cells/mm3 (8.4%). The HIV+ were more likely than HIV− women (4.2 vs 0.5%, respectively, p=0.002) to have moderate neutropenia with white blood cells <2.0×103 cells/mm3 and 8.4% of HIV+ women with CD4 <200 cells/mm3 had moderate neutropenia. In multivariate logistic regression analysis, BMI (OR 0.87/kg/m2, 95% CI 0.82 to 0.93; p<0.001), CD4 200–350 vs HIV− (OR 3.59, 95% CI 1.89 to 6.83; p<0.001) and CD4 <200 cells/mm3 vs HIV− (OR 8.09, 95% CI 4.37 to 14.97; <0.001) had large independent associations with anaemia. There were large independent associations of CD4 <200 cells/mm3 vs HIV− (OR 7.18, 95% CI 0.78 to 65.82; p=0.081) and co-trimoxazole and/or dapsone use (OR 5.69, 95% CI 0.63 to 51.45; p=0.122) with moderate neutropenia.

    Lipodystrophy, and the metabolic alterations (dislipemia, insulin-resistance) associated with human immunodeficiency virus (HIV) infection, is a multifactorial syndrome due to the interaction of host related factors (cellular immune status, diet, gene mutations), viral factors (cytokine synthesis, polyunsaturated fatty acid or PUFA depletion), and pharmacological effects (mitochondrial DNA-polymerase inhibition, lipolysis inhibition, adiponectin synthesis reduction). HIV probably modifies the adipocyte differentiation and the lipid metabolism. This retroviral effect is mediated by proinflammatory cytokines (tumor necrosis factor) and the participation of other factors (drugs, diet), all in the context of a particular host genetic setting. The adipocyte (and several cellular receptors, fatty acids, membrane proteins, and cytokines) plays a central role in the pathogenesis of HIV-associated lipodystrophy. PMID:17040633

    Initial treatment with dolutegravir offers higher efficacy than treatment with efavirenz, darunavir/ritonavir and even with raltegravir in patients with a high viral load. Like ritonavir-boosted protease inhibitors, dolutegravir will probably have a high genetic barrier to resistance and prior genetic testing will not be required in integrase inhibitor-naïve patients. The drug is well tolerated and associated with few treatment discontinuations. It can be administered once daily and the tablet size is small. A fixed-dose combination tablet containing dolutegravir, abacavir and lamivudine will soon be available. Dolutegravir has few interactions with commonly-used drugs. It does not require pharmacological boosting and has no food or time of day restrictions. Because of these characteristics, dolutegravir has a unique profile and is the ideal drug for most HIV-infected patients. PMID:25858610

    Despite marked improvements in the modern treatment era, human immunodeficiency virus (HIV)-infected individuals, particularly those who initiated antiretroviral therapy (ART) at advanced disease stages, continue to have increased age-related morbidity and mortality, compared with the general population. Immune activation and inflammation persist despite suppressive ART and predict many of these morbidities. The goal of this review is to examine the evidence suggesting a link between the persistent inflammatory state and morbidity and mortality in this setting, to describe the impact of early ART initiation on these factors, and to highlight important unanswered questions for the field. We also advance a hypothesis to explain why some morbidities-and their root inflammatory drivers-may be prevented more than others by early ART initiation. PMID:27625430

    Posterior reversible encephalopathy syndrome (PRES) is often associated with hypertension, however recent advances in the understanding of this condition have shown that endothelial dysfunction is responsible for much of the pathogenesis and the condition can occur in the absence of hypertension. This case describes a 32-year-old lady with untreated HIV infection who developed PRES at a normal blood pressure and without opportunistic infection or other conditions known to precipitate PRES. HIV, particularly when untreated, is associated with endothelial dysfunction and this may have been sufficient to cause PRES in this patient. To our knowledge this is the first case to describe PRES in HIV without uncontrolled hypertension, sepsis or other precipitating cause. PMID:22736775

    Background Streptococcus pneumoniae is a major cause of human disease, especially in pre-school children and elderly people, as well as in special risk groups such as asplenic, antibody deficient patients, or presenting disruption of natural barriers. The occurrence of pneumococcal disease has increased with the onset of the HIV epidemic and the emergence of drug-resistance. Case presentation We report the case of an HIV-1-infected patient who experienced three episodes of recurrent pneumococcal meningitis over a 4-year period, despite chemoprophylaxis and capsular vaccination. Conclusions Efficacy of anti-pneumococcal chemoprophylaxis and vaccination in HIV-infected patients are discussed in the light of this particular case. PMID:14613586

    As individuals with HIV infection are living longer, the management of psychiatric disorders has increasingly been incorporated into comprehensive care. Individuals were recruited from an outpatient HIV clinic to assess the prevalence and related associations of current psychiatric disorders and biomarkers. Of the 201 participants who completed the interviews, the median age was 43.5 years, and the majority was male and African American. Most were receiving HIV therapy and 78% of those had achieved virologic suppression. Prevalent psychiatric diagnoses included major depressive disorder, generalized anxiety, and agoraphobia. Alcohol and cocaine/crack abuse and dependence were common substance use disorders. Current receipt of HIV therapy was less common among those diagnosed with generalized anxiety disorder. Agoraphobia was the only disorder associated with unsuppressed viral load. Psychiatric and substance use disorders are highly prevalent among an urban HIV clinic population, although we identified few associations between psychiatric diagnoses and HIV diseases status.

    Despite the availability of effective combination antiretroviral therapy (cART), liver disease is one of the leading causes of morbidity and mortality in Human Immunodeficiency Virus (HIV)-infected individuals, specifically, in the presence of viral hepatitis coinfection. HIV, a single stranded RNA virus, can bind to and activate both Toll-like receptor (TLR)7 and TLR8 in circulating blood mononuclear cells, but little is known about the effect of HIV on TLRs expressed in the liver. HIV can directly infect cells of the liver and HIV-mediated depletion of CD4+ T-cells in the gastrointestinal tract (GI tract) results in increased circulating lipopolysaccharide (LPS), both of which may impact on TLR signaling in the liver and subsequent liver disease progression. The potential direct and indirect effects of HIV on TLR signaling in the liver will be explored in this paper. PMID:22474436

    A 38-year-old white man had a 10-year history of human immunodeficiency virus (HIV) infection (A3), with no episodes of opportunistic diseases and in good immunologic recovery (CD4 cell count: 450 and indetectable HIV viral load) while on HAART. He presented with a two-month history of mild anal symptoms, including pruritus and episodic bleeding. He referred past episodes of anal warts, self-treated with several topical compounds, all proven unsuccessful. Perianal examination showed erythema and scratching. A 0.5cm sized tumor, with infiltration at the base was detected on digital exam, located at 15mm from the anal margin. Local biopsy driven by high-resolution anuscopy (AAR) yielded a final diagnosis of infiltrative epidermoid carcinoma. Might that neoplasia have been prevented? PMID:24139082

    Background: HIV infection may be associated with different arthropathies that are often underdiagnosed. There is also paucity of reported studies of relationship between clinical and laboratory features of HIV-infected patients and articular disorders. Aims: To determine the predictors of articular disorders among HIV-infected patients seen at tertiary hospital Nigeria. Subjects and Methods: Hospital-based cross-sectional descriptive study. Subjects were recruited from outpatient clinics of the study centers. Persons aged 16 years and above were recruited via stratified sampling method. Subjects with trauma, degenerative arthritis, malignancy, hepatitis B surface antigen and anti-hepatitis C virus positivity or previously known to have pulmonary tuberculosis or rheumatological disorders were excluded. Pretest-improved semi-structured questionnaire was administered to the recruited 480 subjects comprising 240 HIV positive subjects (HPS) and 240 HIV-negative subjects (HNS). Blood for relevant laboratory tests and radiographs were done where necessary. Diagnosis of articular disorder was based on American College of Rheumatology and European Spondyloarthropathy Study Group classification guidelines. Statistical Package for Social Sciences version 15 (SPSS Inc., Chicago, IL, USA) was used for data entry, validation, and analysis. Results: Of the 480 participants, both HPS and HNS were made up of 95 males and 145 females. There was statistically significant difference between the frequency of occurrence of articular disorders among the HPS of 37.1% (89/240) and the HIV-negative controls of 16.2% (39/240) (χ2 = 26.63 P = <0.01). Arthralgia frequency of 29.6% (71/240), HIV-associated arthritis 4.6%, (11/240) (Reiter's disease 1.3% (3/240), undifferentiated spondyloarthropathy 1.3%, (3/240) and gout 0.4% (1/240) (were seen among the HPS. Only arthralgia was found among HNS. Erythrocyte sedimentation rate (ESR) and age were the best predictors of arthralgia presence. CD4

    Background With one of the worst HIV prevalence rates in the world, Botswana has made great strides in addressing AIDS. Nevertheless, to fully contain the epidemic, outreach to marginalized groups, including illicit drug users, is critical. Objective To conduct targeted outreach within an intervention trial to recruit HIV-infected drug users and assess HIV disease and nutritional status. Method Recruitment strategies included safeguarding confidentiality, involving ocal health-care professionals, advertising, and participation incentives. Urine toxicology, CD4 cell count, HIV viral load, blood chemistry, plasma micronutrients, dietary history, drug use and morbidity were assessed for two years. Results Targeted outreach identified 138 HIV-infected persons who used marijuana; 18.1% had CD4 cell counts ≤ 350 cells/μL and 39.9% had low BMI. Eligible marijuana users (N=52) had significantly lower BMI (21.8 3.7 vs. 24.3 ± 5.3 kg/m2, P=0.001), higher HIV viral load (4.36 ± 0.89 vs. 4.09 ± 0.89 log10, P=0.018), and higher kilocalorie intake (1924 ± 1055 vs. 1620 ± 926 Kcalories, P=0.025) than those who did not use marijuana (N=748) with similar CD4 cell count. Marijuana users ≥ 40 years old had more opportunistic diseases (P=0.020) than non-users of the same age. Benzodiazepine use was detected among 57 participants and they had higher BMI than marijuana users (24.4 ± 6.8 vs. 21.8 ± 3.7 kg/m2, P= 0.017). Conclusion A population stigmatized by illicit drug use and HIV-infection can be brought into a clinical research setting in Africa. HIV-infected marijuana users were at a risk for higher HIV viral load, lower BMI and more comorbidities than nonusers. Outreach to this marginalized group is important for containing the HIV epidemic. PMID:26855969

  2. Reproductive desire in women with HIV infection in Spain, associated factors and motivations: a mixed-method study

    PubMed Central

    2014-01-01

    Background Antiretroviral therapy has created new expectations in the possibilities of procreation for persons living with HIV. Our objectives were to evaluate reproductive desire and to analyze the associated sociodemographic and clinical factors in HIV-infected women in the Spanish AIDS Research Network Cohort (CoRIS). Methods A mixed qualitative-quantitative approach was designed. Women of reproductive age (18–45) included in CoRIS were interviewed by phone, and data were collected between November 2010 and June 2012 using a specifically designed questionnaire. Reproductive desire was defined as having a desire to be pregnant at present or having unprotected sex with the purpose of having children or wanting to have children in the near future. Results Overall, 134 women were interviewed. Median age was 36 years (IQR 31–41), 55% were Spanish, and 35% were unemployed. 84% had been infected with HIV through unprotected sex, with a median time since diagnosis of 4.5 years (IQR 2.9-6.9). Reproductive desire was found in 49% of women and was associated with: 1) Age (women under 30 had higher reproductive desire than those aged 30–39; OR = 4.5, 95% CI 1.4-14.3); 2) having no children vs. already having children (OR = 3.2; 1.3-7.7 3); Being an immigrant (OR = 2.2; 1.0-5.0); and 4) Not receiving antiretroviral treatment (OR = 3.6; 1.1-12.1). The main reasons for wanting children were related to liking children and wanting to form a family. Reasons for not having children were HIV infection, older age and having children already. Half of the women had sought or received information about how to have a safe pregnancy, 87% had disclosed their serostatus to their family circle, and 39% reported having experienced discrimination due to HIV infection. Conclusions The HIV-infected women interviewed in CoRIS have a high desire for children, and the factors associated with this desire are not fundamentally different from those of women in the general population

  3. Irreversible loss of pDCs by apoptosis during early HIV infection may be a critical determinant of immune dysfunction.

    The dendritic cell subsets myeloid dendritic cells (mDCs) and plasmacytoid dendritic cells (pDCs) play an important role in HIV pathogenesis. While pDCs play a major role in the innate immune response, mDCs are important for induction of the antigen-specific immune response. We studied pDCs and mDCs at different stages of HIV infection, and found that there were decreased percentages of pDCs and mDCs in the advanced stage of the disease (p < 0.0001), and that slow progressors did not show as great a decrease as more healthy individuals. Persons who had acquired infection within the last year showed a normal mDC percentage but a lower pDC percentage (p = 0.0092) than healthy individuals (0.16%). pDC percentages in those with late-stage disease did not revert to normal after successful antiretroviral therapy (ART), whereas mDC percentages reverted to levels comparable to those seen in the healthy population (0.08% pre-ART to 0.18% post-ART; p < 0.0001). The pDC population had high levels of apoptotic markers in those with recent (p = 0.0025) and advanced (p = 0.0012) HIV infection, with no difference in their migratory capacity from controls and slow progressors, indicating that apoptosis is the major mechanism of declining pDC numbers in the circulation. mDCs showed increased levels of apoptotic markers (p = 0.0012), as well as migration (p = 0.03), in those with advanced-stage disease compared to controls, suggesting that both migration and apoptosis contribute to the decline seen in mDCs in the circulation. The irreversible loss of pDCs due to apoptosis seen early in HIV infection may be responsible for an impaired innate anti-HIV immune response. However, the presence of functionally-competent pDCs in slow progressors implies that the loss of pDCs early in infection may be critical to control of HIV infection through innate immune mechanisms, and may influence the progression of disease.

  4. T-cell homeostasis: implications in HIV infection .

    Evidence is presented that a homeostatic mechanism exists that maintains a normal T-cell count, but is unresponsive to abnormalities in CD4+ T-cell count and CD8+ T-cell count. Specifically, we hypothesize that in all cases of T-cell loss, whether selective or not, both CD4+ T cells and CD8+ T cells will be produced until the absolute T-cell count returns to normal, even if this produces or exacerbates abnormalities in the absolute CD4+ T-cell count and absolute CD8+ T-cell count. This hypothesis implies that the selective loss of CD4+ T cells will induce the production of both CD4+ T cells and CD8+ T cells with the result that T-cell count will return to normal, but a persistent CD8+ T-cell lymphocytosis and CD4+ T-cell lymphopenia will be produced. To test this hypothesis, we monitored T-cell reconstitution in mice selectively depleted of CD4+ T cells through treatment with a CD4-specific monoclonal antibody (mAb). Consistent with our hypothesis, the absolute peripheral blood T-cell count in treated mice returned to that of controls after approximately 4 months. However, the absolute CD8+ cell count became 163% of controls and the absolute CD4+ cell count remained less than 63% of controls. Our hypothesis may have implications regarding the pathogenesis and treatment of human immunodeficiency virus (HIV) infection. In particular, the hypothesis implies that the unresolved CD4+ T-cell lymphopenia seen in the first several years of HIV infection is the "natural" consequence of the interaction of a selective CD4+ T-cell depleting virus and a nonselective T-cell replacing homeostatic mechanism.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:8094457

    Research on population mobility and HIV/AIDS risk among migrant populations is quite limited, and research on migrant women workers' vulnerability is further limited. Hong Kong, the Special Administrative Region of China, has currently about 200,000 women migrant workers working as domestic helps. This paper reports migrant women worker's access to AIDS-related health information and health care facilities, perceptions about vulnerability, and risk behaviour profile. Data was collected through a pre-tested questionnaire from a random sample of 2,010 women migrant workers. A majority of the migrant women workers (63.6%) have been living and working in Hong Kong for between 4-10 years. Fifty-four per cent of the respondents felt that being a female they were vulnerable to HIV infection. Overall, the knowledge regarding HIV/AIDS and its route of transmission is inadequate amongst the migrant women workers in Hong Kong. It appears that AIDS-related information education and communication needs of women migrants workers are not met by the current HIV prevention and care activities in Hong Kong. The study indicates that migrant women workers who experienced sexual violence (9%) in Hong Kong perceive themselves to be 'at risk' of HIV infection. Seventy per cent of the respondents reported that they have felt discriminated against in Hong Kong, of which 42% felt discriminated against in Hong Kong hospitals. Addressing discrimination in health care settings is an essential element of AIDS prevention. The discussion urges researchers and policy makers to pay more attention to the vulnerability of migrant women workers. PMID:12204153

  6. Cord blood transplantation for cure of HIV infections.

    Petz, Lawrence

    2013-09-01

    HIV infection has not been cured by antiretroviral drugs or gene therapy, but it has been cured by a hematopoietic cell transplantation (HCT) that was performed for a patient with acute myeloid leukemia and HIV infection using peripheral blood stem cells from an adult donor homozygous for CCR5-Δ32 (CCR5-Δ32/Δ32). HIV has remained undetectable more than 6 years after discontinuation of antiretroviral therapy. However, this approach cannot be readily generalized because of the low prevalence of the CCR5-Δ32 allele and the need for a very close human leukocyte antigen (HLA) match between adult donors and recipients, as when bone marrow or peripheral blood stem cell transplants are performed. In contrast, cord blood (CB) transplants require less stringent HLA matching. CB units are being screened to develop an inventory of cryopreserved homozygous CCR5-Δ32 units available for HCT. One hundred eighty homozygous CCR5-Δ32 units have been identified, and 300 units are projected to provide for white pediatric patients a 73.6% probability of finding an adequately HLA-matched unit with a minimal cell dose of ≥2.5 × 10(7) total nucleated cells (TNC) per kilogram and for white adults a 27.9% probability. With a minimal cell dose requirement of ≥1 × 10(7) TNC per kilogram, the corresponding projected probabilities are 85.6% and 82.1%. CB transplantation does not require as stringent an HLA match between donor and recipient as bone marrow or peripheral blood HCTs, and HCT using cord bloods from donors homozygous for CCR5-Δ32 is, at the present time, the only feasible means of treatment of reasonable numbers of patients who are infected with HIV.

    The reported incidence of venous thromboembolism (VTE) in patients with human immunodeficiency virus (HIV) infection has ranged from 0.25 to 0.96% in clinical studies, but up to 17% at autopsy. A preliminary analysis at our hospital suggested that the frequency of VTE among HIV-positive individuals might be higher than previously reported. To further evaluate this issue, we performed a retrospective study of patients with a diagnosis of VTE and/or HIV infection discharged from our hospital between July 1, 1998 and June 30, 1999. A total of 13,496 patients were discharged during the year of the study. There were 244 patients with VTE and 362 who were HIV-positive. Ten of the 244 patients with VTE were HIV-positive (4.1%). The frequency of VTE among HIV-positive individuals was 10/362 (2.8%) compared to 234/13134 (1.8%) in the non-HIV-positive group, but the difference is not statistically significant. However, in patients under age 50, the frequencies were significantly different: 10/302 (3.31%) versus 35/6594 (0.53%), respectively (p < 0.0001). The frequency of VTE in HIV-positive patients less than 50 years old (3.31%) was greater than in HIV-positive patients over 50 years of age (0/60), but the difference did not reach statistical significance. In contrast, in the non-HIV-positive group, VTE was significantly more frequent in those 50 and older compared to younger patients (3.04% versus 0.53%, p = 0.0001). Statistical analysis indicated that the direction of association between age and diagnosis of VTE differed for HIV-positive patients versus non-HIV-positive patients. Our results suggest that HIV-positive patients under age 50 are at increased risk for VTE compared with non-HIV-positive individuals. PMID:12055028

    Background A screening strategy combining rapid HIV-1/2 (HIV) antibody testing with pooled HIV-1 RNA testing increases identification of HIV infections, but may have other limitations that restrict its usefulness to all but the highest incidence populations. Objective By combining rapid antibody detection and pooled nucleic acid amplification testing (NAAT) testing, we sought to improve detection of early HIV-1 infections in an urban Newark, NJ hospital setting. Study design Pooled NAAT HIV-1 RNA testing was offered to emergency department patients and out-patients being screened for HIV antibodies by fingerstick-rapid HIV testing. For those negative by rapid HIV and agreeing to NAAT testing, pooled plasma samples were prepared and sent to the University of Washington where real-time reverse transcription-polymerase chain reaction (RT-PCR) amplification was performed. Results Of 13,226 individuals screened, 6381 had rapid antibody testing alone, and 6845 agreed to add NAAT HIV screening. Rapid testing identified 115 antibody positive individuals. Pooled NAAT increased HIV-1 case detection by 7.0% identifying 8 additional cases. Overall, acute HIV infection yield was 0.12%. While males represent only 48.1% of those tested by NAAT, all samples that screened positive for HIV-1 RNA were obtained from men. Conclusion HIV-1 RNA testing of pooled, HIV antibody-negative specimens permits identification of recent infections. In Newark, pooled NAAT increased HIV-1 case detection and provided an opportunity to focus on treatment and prevention messages for those most at risk of transmitting infection. Although constrained by client willingness to participate in testing associated with a need to return to receive further results, use of pooled NAAT improved early infection sensitivity.

    OBJECTIVE: To determine the prevalence of HIV infection among pregnant women in Newfoundland. DESIGN: Anonymous unlinked seroprevalence study. SETTING: Newfoundland. PATIENTS: A total of 14911 women receiving prenatal care or undergoing an abortion, representing nearly all pregnancies in Newfoundland from Nov. 1, 1991, to Oct. 31, 1993. OUTCOME MEASURES: HIV antibody status, as determined by enzyme immunoassay of leftover serum samples (initially obtained for routine screening) and confirmation of reactive samples by the Western blot technique, health region of residence, and age group. RESULTS: Of the 14911 serum samples 13 were positive for HIV, for an overall crude prevalence rate of 1 per 1147 or 8.7 per 10000 pregnant women (95% confidence interval [CI] 4.7 to 14.9). Seven of the positive samples were from women residing in the Eastern Health Region of the province, for a crude prevalence rate of 1 per 376 or 26.6 per 10000 pregnant women (95% CI 10.7 to 54.8) for that region. All women found to be HIV positive were 15 to 29 years of age, the peak prevalence (20.8 per 10000 pregnant women [95% CI 9.5 to 39.4]) was observed among those 20 to 24 years. CONCLUSIONS: The overall prevalence rate of 8.7 per 10 000 pregnant women in Newfoundland is the highest provincial rate recorded among those from similar studies in Canada. Although it may be concluded that there are an estimated 125 HIV-positive women of childbearing age in Newfoundland (95% CI 67 to 213), the age-adjusted estimate is 84 (95% CI 36 to 131). This study provides an independent confirmation of an outbreak of HIV infection among women in the Eastern Health Region of the province. PMID:8625023

    Objective To determine maternal risk factors for stillbirth among pregnant HIV-infected women in sub-Saharan Africa. Design Prospective cohort study nested within a micronutrient trial. At enrollment, maternal sociodemographic, obstetric, immunologic, clinical, and nutritional variables were measured. Women were followed through monthly clinic visits until delivery. Multivariate predictors of stillbirth were identified in Poisson regression models. Setting Antenatal clinic in a tertiary care hospital in urban Dar es Salaam, Tanzania. Population N = 1,078 women enrolled between 12 and 27 weeks of gestation. Main outcome measures Stillbirth (delivery of dead baby ≥ 28 weeks’ gestation), fresh stillbirth, and macerated stillbirth. Results Among 1,017 singleton pregnancies, there were 49 stillbirths, yielding a stillbirth risk of 50.0 per 1,000 deliveries (95% Confidence Interval(CI) = 37.2, 65.6). Of stillbirths with known type, 53.7% were fresh and 46.3% macerated. In multivariate analyses, baseline measures of late ( ≥ 21 weeks’ gestation) study entry (Relative Risk (RR) = 2.13, 95% CI = 1.17, 3.87), CD3 count ≥ 1,179 cells/ml (RR = 2.15, 95% CI = 1.16, 4.01), stillbirth history (RR = 3.53, 95% CI = 1.30, 9.59), primiparity (RR = 3.65, 95% CI = 1.83, 7.29), and syphilis infection (RR = 2.06, 95% CI = 1.09, 3.88) predicted increased stillbirth risk. Late study entry, illiteracy, stillbirth history, primiparity, CD3 count ≥ 1,179 cells/ml, gonorrhea infection, and previous hospitalization predicted increased risk of fresh stillbirth, while living alone and syphilis infection predicted increased risk of macerated stillbirth. Conclusions Applying antenatal screening and preventive tools for the socioeconomic, obstetric, immunologic, and clinical risk factors identified may assist in reducing the high incidence of stillbirth among HIV-infected women in urban sub-Saharan Africa.

    Background: The study goal was to describe etravirine pharmacokinetics during pregnancy and postpartum in HIV-infected women. Methods: IMPAACT P1026s and PANNA are on-going, non-randomized, open-label, parallel-group, multi-center phase-IV prospective studies in HIV-infected pregnant women. Intensive steady-state 12-h pharmacokinetic profiles were performed from 2nd trimester through postpartum. Etravirine was measured at two labs using validated ultra performance liquid chromatography (detection limits: 0.020 and 0.026 mcg/mL). Results: Fifteen women took etravirine 200 mg twice-daily. Etravirine AUC0–12 was higher in the 3rd trimester compared to paired postpartum data by 34% (median 8.3 vs. 5.3 mcg*h/mL, p = 0.068). Etravirine apparent oral clearance was significantly lower in the 3rd trimester of pregnancy compared to paired postpartum data by 52% (median 24 vs. 38 L/h, p = 0.025). The median ratio of cord blood to maternal plasma concentration at delivery was 0.52 (range: 0.19–4.25) and no perinatal transmission occurred. Conclusion: Etravirine apparent oral clearance is reduced and exposure increased during the third trimester of pregnancy. Based on prior dose-ranging and safety data, no dose adjustment is necessary for maternal health but the effects of etravirine in utero are unknown. Maternal health and infant outcomes should be closely monitored until further infant safety data are available. Clinical Trial registration: The IMPAACT protocol P1026s and PANNA study are registered at ClinicalTrials.gov under NCT00042289 and NCT00825929. PMID:27540363

    Diarrhea is a common clinical manifestation of HIV infection regardless of whether the patients have AIDS. HIV and malnutrition tend to occur in the same populations, the underprivileged and resource-poor. Malnutrition increases severity and mortality of infection. Occurrence of chronic diarrhea in HIV-infected patients, gut status and pathogenic agents, nutritional status and the crucial role of nutrition are reviewed. Bovine colostrum-based food can be useful for managing chronic diarrhea in HIV-infected patients, enhancing both nutritional and immunological status. PMID:22096401

    Human immunodeficiency virus (HIV) infection is associated with an altered gut microbiome that is not consistently restored with effective antiretroviral therapy (ART). Interpretation of the specific microbiome changes observed during HIV infection is complicated by factors like population, sample type, and ART-each of which may have dramatic effects on gut bacteria. Understanding how these factors shape the microbiome during HIV infection (which we refer to as the HIV-associated microbiome) is critical for defining its role in HIV disease, and for developing therapies that restore gut health during infection.

    More than 1 million HIV-exposed, uninfected infants are born annually to HIV-positive mothers worldwide. This growing population of infants experiences twice the mortality of HIV-unexposed infants. We found that although there were very few differences seen in the microbiomes of mothers with and without HIV infection, maternal HIV infection was associated with changes in the microbiome of HIV-exposed, uninfected infants. Furthermore, we observed that human breast milk oligosaccharides were associated with bacterial species in the infant microbiome. The disruption of the infant's microbiome associated with maternal HIV infection may contribute to the increased morbidity and mortality of HIV-exposed, uninfected infants. PMID:27464748

    HIV infection remains a major problem of public health in Belgium as well as globally. The number of new diagnosies of HIV infection in Belgium remains between two and three daily. Given the dramatic effect of antiretroviral therapy on the mortality due to HIV infection, the number of patients is constantly increasing. The different problems related to HIV care are also changing. Aging of the patients and chronic exposure to antiretroviral medications have induced new complications. We will present in this brief article several new experimental and clinical approaches in which our centre has participated during the last two years. PMID:18214360

  18. Incidence of Hepatitis-C among HIV infected men who have sex with men (MSM) attending a sexual health service: a cohort study

    PubMed Central

    2011-01-01

    Background We aimed to determine the incidence of Hepatitis C (HCV) infection among HIV-infected men who have sex with men (MSM) attending a Sexual Health Centre. Methods A retrospective cohort study was carried out among HIV-infected MSM seen at least once between February 2002 and March 2010. The analysis was restricted to MSM who had had a negative HCV antibody test at least 6 months after their diagnosis for HIV. Duration of follow up was taken from the date of HIV diagnosis to the first positive or last negative HCV antibody test. Results During the time 1445 HIV-infected men attended the clinic of whom 1065 (74%) were MSM. Of these, 869 (82%) were tested for HCV at any time after HIV diagnosis. Of these 869, 69% (620) tested HCV negative at least 6 months after their HIV diagnosis. These 620 men had a mean age of 34 years (range 17-72) at HIV diagnosis and a total of 4,359 person years (PY) of follow up. There were 40 incident cases of HCV, of which 16 were in injecting drug users (IDU) and 24 in non-IDU. The overall incidence of HCV among HIV-infected MSM was 0.9/100 PY (95% CI 0.6-1.2). The incidence among HIV-infected IDU was 4.7/100 PY (95% CI 2.7-7.5) while the incidence among HIV-infected non-IDU was 0.6/100 PY (95% CI 0.4-0.8) (hazard ratio of 8.7 and 95% CI 4.6-16.6, P < 0.001). The majority (78%) were tested for HCV because they developed abnormal liver transaminases (n = 31) or hepatitis symptoms (n = 2), while others (n = 7) were identified through routine HCV testing. Conclusion A considerable proportion of HIV-positive MSM who did not inject drugs contracted HCV, presumably via sexual transmission and the main trigger for investigation was abnormal liver transaminases.

    Background HIV-infected persons have increased risk of MRSA colonization and skin and soft-tissue infections (SSTI). However, no large clinical trial has examined the utility of decolonization procedures in reducing MRSA colonization or infection among community-dwelling HIV-infected persons. Methods 550 HIV-infected adults at four geographically diverse US military HIV clinics were prospectively screened for MRSA colonization at five body locations every 6 months during a 2-year period. Those colonized were randomized in a double-blind fashion to nasal mupirocin (Bactroban) twice daily and hexachlorophene (pHisoHex) soaps daily for 7 days compared to placeboes similar in appearance but without specific antibacterial activity. The primary endpoint was MRSA colonization at 6-months post-randomization; secondary endpoints were time to MRSA clearance, subsequent MRSA infections/SSTI, and predictors for MRSA clearance at the 6-month time point. Results Forty-nine (9%) HIV-infected persons were MRSA colonized and randomized. Among those with 6-month colonization data (80% of those randomized), 67% were negative for MRSA colonization in both groups (p = 1.0). Analyses accounting for missing 6-month data showed no significant differences could have been achieved. In the multivariate adjusted models, randomization group was not associated with 6-month MRSA clearance. The median time to MRSA clearance was similar in the treatment vs. placebo groups (1.4 vs. 1.8 months, p = 0.35). There was no difference on subsequent development of MRSA infections/SSTI (p = 0.89). In a multivariable model, treatment group, demographics, and HIV-specific factors were not predictive of MRSA clearance at the 6-month time point. Conclusion A one-week decolonization procedure had no effect on MRSA colonization at the 6-month time point or subsequent infection rates among community-dwelling HIV-infected persons. More aggressive or novel interventions may be needed to reduce the burden of MRSA in

    The majority of persons infected with HIV live in large metropolitan areas and many such areas have implemented intensified HIV testing programs. A national indicator of HIV testing outcomes is late diagnosis of HIV infection (stage 3, AIDS). Based on National HIV Surveillance System data, 23.3 % of persons with HIV diagnosed in 2012 had a late diagnosis in large MSAs, 26.3 % in smaller MSAs, and 29.6 % in non-metropolitan areas. In the 105 large MSAs, the percentage diagnosed late ranged from 13.2 to 47.4 %. During 2003-2012, the percentage diagnosed late decreased in large MSAs (32.2-23.3 %), with significant decreases in 41 of 105 MSAs overall and among men who have sex with men. Sustained testing efforts may help to continue the decreasing trend in late-stage HIV diagnosis and provide opportunities for early care and treatment and potential reduction in HIV transmission.

    Human immunodeficiency virus (HIV)-infected persons are commonly infected with Cryptosporidium species and Enterocytozoon bieneusi in both developed and developing countries, particularly patients with CD4+ cell counts below 200 cells/μL; 285 HIV-infected patients on highly active antiretroviral therapy (HAART) were enrolled in this study, and both stool and blood specimens were collected from participants. The stool specimens were analyzed and typed for E. bieneusi and Cryptosporidium spp. by polymerase chain reaction (PCR) and DNA sequencing. CD4 count was analyzed using flow cytometry. E. bieneusi and Cryptosporidium were detected in 18 (6.3%) and 4 (1.4%) patients, respectively. The E. bieneusi detected mostly belonged to a new genotype group that, thus far, has only been found in a few humans: genotype Nig4 in 2 patients and two new genotypes related to Nig4 in 12 patients. The Cryptosporidium detected included C. hominis (two patients), C. parvum (one patient), and C. felis (one patient), with the two C. hominis infections belonging to an unusual subtype family. Additional studies are required to determine whether some E. bieneusi genotypes and C. hominis subtypes are more prevalent in HIV patients on HAART. PMID:23629938

    In Canada, the Aboriginal community is most at risk for HIV infection. Aboriginal peoples have disproportionately high rates of violence, drug use, and challenging socioeconomic circumstances. All of this is related to a history of colonization that has left Aboriginal people vulnerable to HIV infection through unsafe sex, needle sharing, and lack of access to health promotion and education. Aboriginal women are at particular risk for HIV infection. They experience a disproportionate degree of trauma, which is associated with colonization, high rates of childhood sexual abuse, and illicit drug use. A history of trauma impacts on access to health care, uptake of antiretroviral therapy, and mortality and morbidity in people with HIV. We describe the case of a 52-year-old, HIV-infected Aboriginal woman. We review the current evidence related to her case, including colonization, intersectionality, post-traumatic stress disorder, depression, revictimization, and substance use. PMID:24012166

    The advent of combination antiretroviral treatment (cART) has been followed by a decrease in HIV-associated morbidity and mortality, but also by an apparent increase in the incidence of non-AIDS-defining cancers (NADCs). The risk of lung cancer is substantially higher in HIV-infected patients than in the general population, in part due to aging and tobacco use, and it is the most frequent NADC. The management of lung cancer in HIV-infected patients has some peculiarities that need to be taken into account. This review focuses on the epidemiology, risk factors, and clinical management of lung cancer in HIV-infected patients. In addition, screening tools and future perspectives are also discussed.

    OBJECTIVES. This paper measured the extent to which human immunodeficiency virus (HIV) infection has spread among the male working-class population of Santos, Brazil. METHODS. Questionnaires on risk behaviors and blood tests were administered to a random sample (n = 395) of male port workers employed by the Santos Port Authority. RESULTS. Although the rate of HIV infection among these men- the working-class male population of Santos-remains low (1.1%), self-reported behavioral risks for HIV infection are common. CONCLUSIONS. There is still time to prevent a widespread outbreak of HIV infection among the hetero-sexual population of Santos and of the transportation corridors emanating from that city. PMID:8712280

    Fourteen asymptomatic HIV-infected Zairian children under 2 years of age displayed social and motor developmental deficits on the Denver Developmental Screening Test when compared with 20 HIV-negative cohorts born to HIV-infected mothers and 16 control children. In a second study, 11 infected children over 2 years of age had sequential motor and visual-spatial memory deficits on the Kaufman Assessment Battery for Children and motor development deficits on the Early Childhood Screening Profiles. HIV infection affects central nervous system structures mediating motor and spatial memory development, even in seemingly asymptomatic children. Furthermore, maternal HIV infection compromises the labor-intensive provision of care in the African milieu and undermines global cognitive development in even uninfected children. PMID:7737068

    2016-10-01

    The impact of human immunodeficiency virus (HIV) infection on innate and adaptive immune activation occurs in the context of host factors, which serve to augment or dampen the physiologic response to the virus. Independent of HIV infection, nutritional status, particularly body composition, affects innate immune activation through a variety of conditions, including reduced mucosal barrier defenses and microbiome dysbiosis in malnutrition and the proinflammatory contribution of adipocytes and stromal vascular cells in obesity. Similarly, T-cell activation, proliferation, and cytokine expression are reduced in the setting of malnutrition and increased in obesity, potentially due to adipokine regulatory mechanisms restraining energy-avid adaptive immunity in times of starvation and exerting a paradoxical effect in overnutrition. The response to HIV infection is situated within these complex interactions between host nutritional health and immunologic function, which contribute to the varied phenotypes of immune activation among HIV-infected patients across a spectrum from malnutrition to obesity.

    We compared adjusted bone mineral density (BMD) changes between human immunodeficiency virus (HIV)-infected individuals during the first approximately 7.5 years after antiretroviral therapy (ART) initiation and HIV-uninfected controls. HIV-infected individuals (n = 97) had significantly greater adjusted BMD decline than controls (n = 614) during the first 96 weeks of ART. Subsequently, the rate of BMD decline slowed in HIV-infected individuals but remained greater than the rate of decline in HIV-uninfected individuals at the lumbar spine but not at the hip. In HIV-infected individuals after 96 weeks, no HIV- or treatment-related characteristic was associated with BMD loss, but lower lean body mass was associated with greater BMD loss at both lumbar spine and hip.

    Injection drug use contributes to considerable global morbidity and mortality associated with human immunodeficiency virus (HIV) infection and AIDS and other infections due to blood-borne pathogens through the direct sharing of needles, syringes, and other injection equipment. Of ~16 million injection drug users (IDUs) worldwide, an estimated 3 million are HIV infected. The prevalence of HIV infection among IDUs is high in many countries in Asia and eastern Europe and could exacerbate the HIV epidemic in sub- Saharan Africa. This review summarizes important components of a comprehensive program for prevention of HIV infection in IDUs, including unrestricted legal access to sterile syringes through needle exchange programs and enhanced pharmacy services, treatment for opioid dependence (i.e., methadone and buprenorphine treatment), behavioral interventions, and identification and treatment of noninjection drug and alcohol use, which accounts for increased sexual transmission of HIV. Evidence supports the effectiveness of harm-reduction programs over punitive drug-control policies. PMID:20397939

    The aim of this study was to assess morphological and morphometrical alterations of oral squamous epithelial cells in type 1 HIV infected individuals. Oral smears were collected from tongue and buccal mucosa of 30 HIV infected (experimental) and 30 non-infected (control) individuals by liquid-based exfoliative cytology. The cells were morphologically analyzed and the nuclear area (NA), the cytoplasmic area (CA) and the nucleus-to-cytoplasm area ratio (NA/CA) were calculated. No morphological differences were found between the groups. The mean values of CA were decreased in tongue (P=.00006) and buccal mucosa (P=.00242) in HIV infected individual, while mean values of NA were increased (P=.00308 and .00095, respectively) in the same group. NA/CA ratio for experimental group was increased in both collected places, with P=.00001 (tongue) and P=.00000 (buccal mucosa). This study revealed that HIV infection was able to induce morphometrical changes on the oral epithelial cells. PMID:21198427

    Eradication of HIV infection will require the identification of all cellular reservoirs that harbor latent infection. Despite low or lack of CD4 receptor expression on Vδ2 T cells, infection of these cells has previously been reported. We found that upregulation of the CD4 receptor may render primary Vδ2 cells target for HIV infection in vitro and we propose that HIV-induced immune activation may allow infection of γδ T cells in vivo. We assessed the presence of latent HIV infection by measurements of DNA and outgrowth assays within Vδ2 cells in 18 aviremic patients on long-standing antiretroviral therapy. In 14 patients we recovered latent but replication-competent HIV from highly purified Vδ2 cells demonstrating that peripheral Vδ2 T cells are a previously unrecognized reservoir in which latent HIV infection is unexpectedly frequent.

    Voluntary counseling and testing (VCT) is recommended to facilitate early identification of HIV infection. Data from VCT centers in Goiás and Federal District, Central Brazil, evaluated HIV prevalence and identified risk factors for HIV among individuals ages 13 years and older. Results indicated a 1.5% overall prevalence of HIV. Factors independently associated with HIV infection were: getting tested in a large city, being illiterate, having had a previous HIV test, living with an HIV-infected sexual partner, and being a noninjection illicit drug user. Being referred by friends was strongly associated with HIV infection. For men, being a health care worker, sex worker, man who has sex with men, or injection drug user were significant. In Central Brazil, HIV remains concentrated in males and subpopulations with known risk behaviors. Higher prevalence among individuals referred to VCT by friends highlights the importance of social network-based HIV prevention interventions in Brazil. PMID:23465400

    Context: Little is known about renin-angiotensin-aldosterone system (RAAS) activation in relationship to visceral adipose tissue (VAT) accumulation in HIV-infected patients, a population at significant risk for insulin resistance and other metabolic disease. Design: Twenty HIV and 10 non-HIV-infected subjects consumed a standardized low sodium or liberal sodium diet to stimulate or suppress the RAAS, respectively. RAAS parameters were evaluated in response to each diet and a graded angiotensin II infusion. Further analyses were performed after groups were substratified by median VAT measured by magnetic resonance imaging. Results: Aldosterone concentrations during the low-sodium diet were higher in HIV than non-HIV-infected subjects [13.8 (9.7, 30.9) vs 9.2 (7.6, 13.6) ng/dL, P = .03] and increased across groups stratified by visceral adipose tissue (VAT) [8.5 (7.1, 12.8), 9.2 (8.1, 21.5), 11.4 (9.4, 13.8), and 27.2 (13.0, 36.9) ng/dL in non-HIV-infected without increased VAT, non-HIV-infected with increased VAT, HIV-infected without increased VAT, HIV-infected with increased VAT, respectively, overall trend P = .02]. Under this condition, plasma renin activity [3.50 (2.58, 4.65) vs 1.45 (0.58, 2.33) ng/mL · h, P = .002] was higher among the HIV-infected subjects with vs without increased VAT. Differences in the suppressibility of plasma renin activity by graded angiotensin infusion were seen stratifying by VAT among the HIV-infected group (P < .02 at each dose). In addition, aldosterone (P = .007) was an independent predictor of insulin resistance in multivariate modeling, controlling for VAT and adiponectin. Conclusion: These data suggest excess RAAS activation in relationship to visceral adiposity in HIV-infected patients that may independently contribute to insulin resistance. Mineralocorticoid blockade may have therapeutic potential to reduce metabolic complications in HIV-infected patients with increased visceral adiposity. PMID:26086328

    Compared with thrice-weekly intermittent antituberculosis therapy (ATT), the use of daily ATT during the intensive phase has shown improved survival in HIV infected patients with tuberculosis. However, the optimal duration of daily ATT before initiating intermittent ATT is not well known. In this study, we analysed the mortality of HIV-related tuberculosis according to the duration of daily ATT before switching to thrice-weekly ATT in patients who completed at least two months of treatment in an HIV cohort study. Statistical analysis was performed using Cox proportional hazard models. To relax the linearity assumption in regression models and to allow for a flexible interpretation of the relationship between duration of daily ATT and mortality, continuous variables were modelled using restricted cubic splines. The study included 520 HIV infected patients with tuberculosis and 8,724.3 person-months of follow-up. The multivariable analysis showed that the mortality risk was inversely correlated with the duration of daily ATT before switching to intermittent therapy during the first 30 days of ATT but, after approximately 30 days of treatment, differences were not statistically significant. The results of this study suggest that daily ATT should be given for at least 30 days before switching to intermittent ATT in HIV infected patients with tuberculosis.

    The aim of the study was to examine and describe the individual and structural-environmental factors that shape the vulnerability of brothel-based female sex workers (FSWs) in Ibadan, southwest Nigeria to HIV infection. A descriptive qualitative research design was utilised to elicit data, using in-depth interviews and focus group discussions, from 60 randomly selected participants in four brothels. A thematic analysis of data was undertaken following transcription and validation of interviews. Five themes emerged from the data: (i) flawed knowledge and fatalistic attitudes; (ii) the psychosocial and economic context of sex work; (iii) religious beliefs, stigma and risk taking; (iv) barriers to HIV testing; and (v) legal and policy constraints to sex work. We describe the complex interaction between these themes and how they combine to increase the risk of HIV infection among FSWs. The impact of previous interventions to reduce the risk of HIV infection among FSWs has been limited by personal and structural factors; hence we recommend that new strategies that recognise the practical constraints to HIV prevention among FSWs are urgently needed to make the environment of commercial work safer for FSWs, their clients, and by extension the general population.

    Objective: We evaluated the separate and interactive associations of menopausal stage, menopausal symptoms, and HIV infection on cognition. We hypothesized that HIV-infected, perimenopausal women would show the greatest cognitive difficulties and that menopausal symptoms would be inversely associated with cognition. Methods: This cross-sectional study included 708 HIV-infected and 278 HIV-uninfected, pre-, peri-, or postmenopausal women (64% African-American; median age 44 years) from the Women’s Interagency HIV Study. Participants completed tests of verbal learning and memory, attention/processing speed, and executive function. We administered a menopausal symptom questionnaire that assessed anxiety, vasomotor, and sleep symptoms and obtained measures of depressive symptoms. Results: In multivariable regression analyses controlling for relevant covariates, HIV infection, but not menopausal stage, was associated with worse performance on all cognitive measures (p’s<0.05). Depressive symptoms were associated with lower cognitive performance on measures of verbal learning and memory, attention, and executive function (p’s<0.05); anxiety symptoms were associated with lower performance on measures of verbal learning and memory (p’s<0.05). Vasomotor symptoms were associated with worse attention (p<0.05). HIV and anxiety symptoms interacted to influence verbal learning (p’s<0.05); elevated anxiety was associated with worse verbal learning in HIV-infected women only. Conclusion: Vasomotor, depressive, and anxiety symptoms, but not menopausal stage, were associated with worse cognitive performance in both HIV-infected and uninfected women, although elevated anxiety symptoms were associated with verbal learning deficits more in HIV-infected women. Since cognitive problems can interfere with everyday functioning including treatment adherence, it may be important to screen and treat anxiety in HIV-infected women. PMID:24496085

    Abstract Studies have found HIV-infected patients to be at increased risk of myocardial infarction, which may be caused by coronary microvascular dysfunction. For the first time among HIV-infected patients, we assessed the myocardial flow reserve (MFR) by Rubidium-82 (82Rb) positron emission tomography (PET), which can quantify the coronary microvascular function. MFR has proved highly predictive of future coronary artery disease and cardiovascular events in the general population. In a prospective cross-sectional study, HIV-infected patients all receiving antiretroviral therapy (ART) with full viral suppression and HIV-uninfected controls were scanned using 82Rb PET/computed tomography at rest and adenosine-induced stress, thereby obtaining the MFR (stress flow/rest flow), stratified into low ≤1.5, borderline >1.5 to 2.0, or normal >2.0. Fifty-six HIV-infected patients and 25 controls were included. The HIV-infected patients had a mean age of 53 years (range 37–68 years) with 23% active smokers. The controls had a mean age of 52 years (range 36–68 years) and 26% active smokers. In the HIV-infected group 73% had a normal MFR, 17% borderline, and 10% low values of MFR. Among controls these values were 71%, 19%, and 10%, respectively (P = 0.99). However, the HIV-infected group had lower values of stress myocardial blood flow (MBF) (2.63 ± 0.09 mL/g/min vs 2.99 ± 0.14 mL/g/min; P = 0.03). We found no evidence of decreased MFR as assessed by 82Rb PET among HIV-infected patients on stable ART with full viral suppression compared with HIV-uninfected controls. We did notice a decreased MBF during stress. PMID:26512605

    Objective To investigate the effects of HIV infection in children on heart electrical conduction, particularly to delineate the effects of HIV infection from treatment. Methods On a 12-lead ECG, available for 37 antiretroviral therapy (ART) naïve, 42 ART-exposed vertically-acquired HIV-infected and 50 healthy children in Jakarta, Indonesia, we measured cardiac conduction parameters: PR, QRS, and QTc (corrected using Bazett's formula) intervals. The associations between HIV infection/treatment status and ECG intervals were evaluated using general linear modelling with further adjustment for potential confounders or intermediary variables. Findings are presented as (adjusted) mean differences between each of the two HIV groups and healthy children. Results Although not exceeding the clinical threshold for long QT (QTc >460 ms for girls and >440 ms for boys) compared to healthy children, mean QTc intervals were longer in ART-naïve (difference 18.2 ms, 95% CI 7.0 to 29.3) and, to greater extent, in ART-exposed HIV-infected children (difference 28.9 ms, 19.3 to 38.5). Following adjustment for RR interval, age and height, prolongation of PR interval was seen only in ART-naïve HIV-infected children (difference 12.9 ms, 2.4 to 23.3). Cardiac mass/function, high-sensitive C reactive protein, cholesterol and glycated haemoglobin levels, systolic and diastolic blood pressures, or postnatal parental smoking exposure did not affect these associations. No difference in the QRS interval was observed between groups. Conclusions Prolongation of the QTc interval occurs in ART-naïve HIV-infected children and, to a greater extent, in the ART-exposed children, whereas a longer PR interval appears to be seen only among ART-naïve HIV-infected children.

    Introduction: Previous unblinded trials have shown increased malaria among HIV-infected adults on antiretroviral therapy (ART) who stop cotrimoxazole (CTX) prophylaxis. We investigated the effect of stopping CTX on malaria in HIV-infected adults on ART in a double-blind, placebo-controlled trial. Methods: HIV-infected Ugandan adults stable on ART and CTX with CD4+ cell count at least 250 cells/μl were randomized (1 : 1) to continue CTX or stop CTX and receive matching placebo (COSTOP trial; ISRCTN44723643). Clinical malaria was defined as fever and a positive blood slide, and considered severe if a participant had at least one clinical or laboratory feature of severity or was admitted to hospital. Malaria incidence and rate ratios were estimated using random effects Poisson regression, accounting for multiple episodes. Results: A total of 2180 participants were enrolled and followed for a median of 2.5 years; 453 malaria episodes were recorded. Malaria incidence was 9.1/100 person-years (pyrs) [95% confidence interval (CI) = 8.2–10.1] and was higher on placebo (rate ratio 3.47; CI = 2.74–4.39). Malaria in the placebo arm decreased over time; although incidence remained higher than in the CTX arm, the difference between arms reduced slightly (interaction P value = 0.10). Fifteen participants experienced severe malaria (<1%); overall incidence was 0.30/100 pyrs (CI = 0.18–0.49). There was one malaria-related death (CTX arm). Conclusion: HIV-infected adults – who are stable on ART and stop prophylactic CTX – experience more malaria than those that continue, but this difference is less than has been reported in previous trials. Few participants had severe malaria. Further research might be useful in identifying groups that can safely stop CTX prophylaxis. PMID:26558729

    Long-term follow-up of persons infected with HIV infection is essential to optimize clinical outcomes. However, limited data exist on the rates of dropout (DO) from HIV care and factors associated with DO especially from resource-limited settings. We conducted a retrospective analysis of the data available at YRGCARE, a private HIV care provider in south India that has registered over 15,000 HIV-infected persons since its inception in 1993. We included 7995 patients who registered for care between 1 January 2004 and 31 December 2009. A dropout was defined as a person who registered for care during this period and had not been seen in the clinic for >1 year. Logistic regression was used to examine factors associated with DO from clinical care. The median age of the patients registered for care was 34 years; 66% were male and 83% were married. The overall DO rate was 38.1 per 100 person-years - the majority of the DOs occurred within 6 months from registration. In multivariate analyses, patients who were enrolled in clinical studies/projects entitling them to free medications and retention staff (Odds Ratio [OR]: 0.65) or were on antiretroviral therapy (ART; OR: 0.37) or had a CD4 > 350 at the last visit (OR: 0.20) were significantly less likely to DO from clinical care. We observed a high rate of DO from clinical care at this tertiary HIV clinic in Chennai, India. Making ART available free of charge in the private sector and providing incentives/benefits for attending clinic visits as is routinely done in clinical trials might help improve retention.

    Worldwide, more than three million children are infected with HIV, 90% of whom live in sub-Saharan Africa. As the HIV epidemic matures and antiretroviral treatment is scaled up, children with HIV are reaching adolescence in large numbers. The growing population of adolescents with perinatally acquired HIV infection living within this region presents not only unprecedented challenges but also opportunities to learn about the pathogenesis of HIV infection. In this Review, we discuss the changing epidemiology of paediatric HIV and the particular features of HIV infection in adolescents in sub-Saharan Africa. Longstanding HIV infection acquired when the immune system is not developed results in distinctive chronic clinical complications that cause severe morbidity. As well as dealing with chronic illness, HIV-infected adolescents have to confront psychosocial issues, maintain adherence to drugs, and learn to negotiate sexual relationships, while undergoing rapid physical and psychological development. Context-specific strategies for early identification of HIV infection in children and prompt linkage to care need to be developed. Clinical HIV care should integrate age-appropriate sexual and reproductive health and psychological, educational, and social services. Health-care workers will need to be trained to recognise and manage the needs of these young people so that the increasing numbers of children surviving to adolescence can access quality care beyond specialist services at low-level health-care facilities.

    Objective. To compare frequencies of complications among HIV-infected and-uninfected women undergoing common gynecological surgical procedures in inpatient settings. Methods. We used 1994–2007 data from the Nationwide Inpatient Sample of the Healthcare Cost and Utilization Project, a nationally representative sample of inpatient hospitalizations. Our analysis included discharge records of women aged ≥15 undergoing hysterectomy, oophorectomy, salpingectomy for ectopic pregnancy, bilateral tubal sterilization, or dilation and curettage. Associations between HIV infection status and surgical complications were evaluated in multivariable logistic regression models, adjusting for key covariates. Results. For each surgery, HIV infection was associated with experiencing ≥1 complication. Adjusted ORs ranged from 2.0 (95% confidence interval (CI): 1.7, 2.2) for hysterectomy with oophorectomy to 3.1 (95% CI: 2.4, 4.0) for bilateral tubal sterilization with no comorbidity present. HIV infection was positively associated with extended length of stay and infectious complications of all of the surgeries examined. For some surgeries, it was positively associated with transfusion and anemia due to acute blood loss. Among HIV-infected women, the odds of infectious and other complications did not decrease between 1994–2000 and 2001–2007. Conclusion. HIV infection was associated with elevated frequencies of complications of gynecologic surgeries in the US, even in the era of HAART. PMID:22675242

    Background. Anaemia is a common complication of human immunodeficiency virus (HIV) infection. The aim of this study was to investigate the impact of HIV infection and zidovudine on red blood cells (RBC) parameters and urine methylmalonic acid (UMMA) levels in patients with HIV infection. Material and Methods. A cross-sectional study involving 114 subjects, 94 of which are HIV-infected nonanaemic and 20 HIV negative subjects (Cg) as control. Full blood count parameters and urine methylmalonic acid (UMMA) level of each subject were determined. Associations were determined by Chi-square test and logistic regression statistics where appropriate. Results. Subjects on zidovudine-based ART had mean MCV (93 fL) higher than that of control group (82.9 fL) and ART-naïve (85.9 fL) subjects and the highest mean RDW. Mean UMMA level, which reflects vitamin B12 level status, was high in all HIV-infected groups but was significantly higher in ART-naïve subjects than in ART-experienced subjects. Conclusion. Although non-zidovudine therapy may be associated with macrocytosis (MCV > 95 fL), zidovudine therapy and ART naivety may not. Suboptimal level of vitamin B12 as measured by high UMMA though highest in ART-naïve subjects was common in all HIV-infected subjects. PMID:26989408

    Chronic immune activation despite long-term therapy poses an obstacle to immune recovery in HIV infection. The role of antigen presenting cells (APCs) in chronic immune activation during HIV infection remains to be fully determined. APCs, the frontline of immune defense against pathogens, are capable of distinguishing between pathogens and non-pathogenic, commensal bacteria. We hypothesized that HIV infection induces dysfunction in APC immune recognition and response to some commensal bacteria and that this may promote chronic immune activation. Therefore we examined APC inflammatory cytokine responses to commensal lactobacilli. We found that APCs from HIV-infected patients produced an enhanced inflammatory response to Lactobacillus plantarum WCFS1 as compared to APCs from healthy, HIV-negative controls. Increased APC expression of TLR2 and CD36, signaling through p38-MAPK, and decreased expression of MAP kinase phosphatase-1 (MKP-1) in HIV infection was associated with this heightened immune response. Our findings suggest that chronic HIV infection enhances the responsiveness of APCs to commensal lactobacilli, a mechanism that may partly contribute to chronic immune activation. PMID:24023646

    HIV-infected men who have sex with men (MSM) have the highest rates of anal dysplasia and anal cancer when compared to HIV-uninfected MSM and when compared to HIV-infected heterosexual men and women. Despite significantly increasing rates of anal dysplasia and anal cancer in HIV-infected MSM, in many settings, no standard protocol is in place to screen for anal dysplasia in this high-risk group. A practice improvement project was conducted at a primary care health center to educate the HIV health care team about anal Pap screening in an effort to increase provider knowledge and rates of anal Pap screening performed as part of primary comprehensive care for HIV-infected MSM. Increased health care provider knowledge of anal Pap screening within this setting resulted in increased anal Pap screening for HIV-infected MSM. Routine screening leads to improved surveillance and treatment of precancerous lesions, decreasing morbidity and mortality in HIV-infected MSM. PMID:26427364

  10. HIV infection in children--impact upon ENT doctors.

    The global epidemic of HIV infection remains appalling. By 2001, there were an estimated 1.4 million HIV-infected children, with 4.5 million deaths. In the UK, paediatric cases are clustered around population centres where there are high concentrations of infected immigrant adults, and to a lesser extent, areas where IV drug abuse is common. The highest incidence remains in London and the southeast. With the national redistribution of immigrant and refugee families, any doctor in any specialty may expect to be involved with children who are HIV positive, or have clinical AIDS. The majority of children are infected vertically, i.e. infection of the infant from an infected mother in the pre-, peri-, or post-natal periods. Rates of transmission vary from 15-20% in the developed countries. Children with HIV infection may have their primary presentation to ENT doctors, who should have appropriate thresholds for suspecting the diagnosis. The most common presenting features include persistent generalised lymphadenopathy, hepatosplenomegaly, chronic/recurrent diarrhoea, poor growth, and fever. Fifteen to twenty percent of untreated children will present with an AIDS-defining illness by 12 months, typically with Pneumocystis pneumonia at approximately 3-4 months of age. Seventy percent of perinatally infected children will exhibit some signs or symptoms by 12 months Without treatment, the median age to progression to AIDS is approximately 6 years, and 25-30% will have died by this age. The median age of death is approximately 9 years. Children may also present with repeated/unusual ear infections, sinus disease (inc. mastoiditis), tonsillitis, orbital/peri-orbital cellulitis, oral candidiasis, and dental infections. Infections with streptococcus pneumoniae and group A streptococcus are common, and often progress to severe systemic infection with an appreciable mortality. Infections may be due to unusual pathogens such as Pseudomonas, 'typical' and atypical Mycobacteria

    The advent of Highly Active Antiretroviral Therapy (HAART) has radically changed incidence characteristics and prognosis of HIV-positive patients affected by lymphomas. At this time there is consensus in the literature that, in first line, HIV-positive patients should always be treated with curative intent preferentially following the same approach used in the HIV-negative counterpart. On the contrary, an approach of salvage therapy in HIV-positive lymphomas is still a matter of debate given that for a wide range of relapsed or resistant HIV-negative Hodgkin's disease (HD) and non-Hodgkin lymphoma (NHL) patients, autologous peripheral or allogeneic stem cell transplantation are among the established options. In the pre-HAART era, therapeutic options derived from pioneering experiences gave only anecdotal success, either when transplantation was used to cure lymphomas or to improve HIV infection itself. Concerns relating to the entity, quality, and kinetics of early and late immune reconstitutions and the possible worsening of underlying viroimmunological conditions were additional obstacles. Currently, around 100 relapsed or resistant HIV-positive lymphomas have been treated with an autologous peripheral stem cell transplantation (APSCT) in the HAART era. Published data compared favorably with any previous salvage attempt showing a percentage of complete remission ranging from 48% to 90%, and overall survival ranging from 36% to 85% at median follow-up approaching 3 years. However, experiences are still limited and have given somewhat confounding indications, especially concerning timing and patients' selection for APSCT and feasibility and outcome for allogeneic stem cell transplant. Moreover, little data exist on the kinetics of immunological reconstitution after APSCT or relevant to the outcome of HIV infection. The aim of this review is to discuss current knowledge of the role of allogeneic and autologous stem cell transplantation as a modality in the cure of

    OBJECTIVE: To determine the seroprevalence and correlates of HIV infection in a subpopulation of women of childbearing age in Montreal. DESIGN: Anonymous unlinked seroprevalence study. SETTING: Pregnancy termination unit in a teaching hospital in Montreal. PARTICIPANTS: Women presenting for abortion from July 1989 to June 1993 who resided in Quebec and were not known to have HIV infection; 12,017 (99.6%) of 12,068 eligible women were included in the study. INTERVENTION: HIV antibody testing of serum left over from samples obtained for routine Rh typing; the same algorithm as for serodiagnostic testing, namely enzyme immunoassay (EIA) followed by confirmatory testing of repeatedly EIA-reactive samples, was used. OUTCOME MEASURES: HIV serostatus by age, marital status, region of residence (metropolitan Montreal versus other), country of birth and number of living children. RESULTS: Most (84.7%) of the subjects resided in metropolitan Montreal. The median age was 27.0 (range 13 to 50) years. The serum samples of 22 women were confirmed to be HIV positive, for an overall seroprevalence rate of 1.8 per 1000 (95% confidence interval 1.1 to 2.8). The seroprevalence rate did not vary significantly by age, marital status, region of residence or study year. However, it was strongly correlated with country of birth: Canada 0.16, Haiti 23.5, HIV-endemic countries other than Haiti 5.3 and non-HIV-endemic countries other than Canada 0.0 per 1000. The seroprevalence rate among women born in Haiti was 147 times higher than that among women born in Canada (p < 0.0001). Of the women born in Haiti the rate was 3.0 times greater among those who immigrated to Canada in 1985 or later than among those who immigrated earlier (p = 0.047). CONCLUSIONS: The results of this study indicate that the HIV seroprevalence rate among women in Montreal is strongly associated with country of birth, women born in HIV-endemic countries, especially Haiti, having the highest rate. These results will help

    Objectives Abnormal hearing tests have been noted in HIV-infected patients in several studies, but the nature of the hearing deficit has not been clearly defined. We performed a cross-sectional study of both HIV+ and HIV− individuals in Tanzania using an audiological test battery. We hypothesized that HIV+ adults would have a higher prevalence of abnormal central and peripheral hearing test results compared to HIV− controls. Additionally, we anticipated that the prevalence of abnormal hearing assessments would increase with anti-retroviral therapy (ART) use, and treatment for tuberculosis (TB). Design Pure-tone thresholds, distortion product otoacoustic emissions (DPOAEs), tympanometry, and a gap detection test were performed using a laptop-based hearing testing system on 751 subjects (100 HIV− in the U.S., plus 651 in Dar es Salaam Tanzania including 449 HIV+ [130 ART− and 319 ART+], and 202 HIV−, subjects. No U.S. subjects had a history of TB treatment. In Tanzania, 204 of the HIV+, and 23 of the HIV−, subjects had a history of TB treatment. Subjects completed a video and audio questionnaire about their hearing as well as a health history questionnaire. Results HIV+ subjects had reduced DPOAE levels compared to HIV− subjects, but their hearing thresholds, tympanometry results, and gap detection thresholds were similar. Within the HIV+ group, those on ART reported significantly greater difficulties understanding speech-in-noise, and were significantly more likely to report that they had difficulty understanding speech than the ART− group. The ART+ group had a significantly higher mean gap detection threshold compared to the ART− group. No effects of TB treatment were seen. Conclusions The fact that the ART+/ART− groups did not differ in measures of peripheral hearing ability (DPOAEs, thresholds), or middle ear measures (tympanometry), but that the ART+ group had significantly more trouble understanding speech and higher gap detection thresholds

    During the extended clinically latent period associated with Human Immunodeficiency Virus (HIV) infection the virus itself is far from latent. This phase of infection generally comes to an end with the development of symptomatic illness. Understanding the factors affecting disease progression can aid treatment commencement and therapeutic monitoring decisions. An example of this is the clear utility of CD4+ T-cell count and HIV-RNA for disease stage and progression assessment. Elements of the immune response such as the diversity of HIV-specific cytotoxic lymphocyte responses and cell-surface CD38 expression correlate significantly with the control of viral replication. However, the relationship between soluble markers of immune activation and disease progression remains inconclusive. In patients on treatment, sustained virological rebound to >10 000 copies/mL is associated with poor clinical outcome. However, the same is not true of transient elevations of HIV RNA (blips). Another virological factor, drug resistance, is becoming a growing problem around the globe and monitoring must play a part in the surveillance and control of the epidemic worldwide. The links between chemokine receptor tropism and rate of disease progression remain uncertain and the clinical utility of monitoring viral strain is yet to be determined. The large number of confounding factors has made investigation of the roles of race and viral subtype difficult, and further research is needed to elucidate their significance. Host factors such as age, HLA and CYP polymorphisms and psychosocial factors remain important, though often unalterable, predictors of disease progression. Although gender and mode of transmission have a lesser role in disease progression, they may impact other markers such as viral load. Finally, readily measurable markers of disease such as total lymphocyte count, haemoglobin, body mass index and delayed type hypersensitivity may come into favour as ART becomes

    Background HIV-infected (HIV+) men face cancer treatment disparities which impact outcome. Prostate cancer (PCa) treatment and treatment appropriateness in HIV+ men are unknown. Methods We used electronic chart review to conduct a retrospective cohort study of 43 HIV+ cases with PCa and 86 age- and race-matched HIV-uninfected (HIV−) controls with PCa, aged 40–79, from 2001–2012. We defined treatment appropriateness using National Comprehensive Cancer Network (NCCN) guidelines and the Charlson Co-morbidity Index (CCI) to estimate life expectancy. Results Median age was 59.5 years at PCa diagnosis. Median CD4+ T-cell count was 459.5cells/mm3, 95.3% received antiretroviral therapy, and 87.1% were virally suppressed. Radical prostatectomy (RP) was the primary treatment for 39.5% of HIV+ and 71.0% of HIV− men (p= 0.004). Only 16.3% of HIV+ vs. 57.0% of HIV− men received open RP (p< 0.001). HIV+ men received more radiotherapy (25.6% vs. 16.3%, p= 0.13). HIV was negatively associated with open RP (OR= 0.03, p= 0.007), adjusting for insurance and CCI. No men were undertreated. Fewer HIV+ men received appropriate treatment (89.2% vs. 100%, p= 0.003), due to 4 overtreated HIV+ men. Excluding AIDS from the CCI still resulted in fewer HIV+ men receiving appropriate treatment (94.6% vs. 100%, p = 0.03). Conclusion PCa in HIV+ men is largely appropriately treated. Under-or overtreatment may occur from difficulties in life expectancy estimation. HIV+ men may receive more radiotherapy and fewer RPs, specifically open RPs. Impact Research on HIV/AIDS survival indices and etiologies and outcomes of this PCa treatment disparity in HIV+ men is needed. PMID:25063519

    The prevalence of cigarette smoking among persons living with HIV/AIDS (PLWHA) is approximately 40%, significantly higher than that of the general population. Identifying predictors of successful smoking cessation for PLWHA is necessary to alleviate the morbidity and mortality associated with smoking in this population. Weight gain has been associated with smoking relapse in the general population, but has not been studied among PLWHA. Data from 474 PLWHA enrolled in a smoking cessation randomized clinical trial were analyzed to examine the effect of BMI change, from baseline to 3-month follow-up, on smoking outcomes using multiple logistic regression. The odds of 7-day smoking abstinence at 3-month follow-up were 4.22 (95% CI = 1.65, 10.82) times higher for participants classified as BMI decrease and 4.22 (95% CI = 1.62, 11.01) times higher for participants classified as BMI increase as compared to participants with a minimal increase or decrease in BMI. In this sample, both weight gain and loss following smoking cessation were significantly associated with abstinence at 3-month follow-up among HIV-infected smokers. Further research and a better understanding of predictors of abstinence will encourage more tailored interventions, with the potential to reduce morbidity and mortality. PMID:26666313

    Intravaginal practices (IVPs) are associated with an increased risk of bacterial vaginosis and may play a role in HIV transmission. The objective of this study was to identify the importance of factors underlying the decision to engage in IVP using conjoint analysis; a novel statistical technique used to quantify health-related decisions. This study was a cross-sectional study. HIV-infected women in Zambia completed audio computer-administered self-interview questionnaires assessing demographic, risk factors and IVPs. Reasons for engaging in IVPs were explored using conjoint questionnaires. Conjoint analysis was used to identify the relative importance of factors for engaging in IVPs. Results of the conjoint analysis demonstrated that hygiene was the most important reason for engaging in IVPs (mean importance score = 61, SD = 24.3) followed by partner's preference (mean importance score = 20, SD = 14.4) and health (mean importance score = 17, SD = 13.5). When making the decision to engage in IVPs, women rank the importance of hygiene, partner preference and health differently, according to their personal characteristics. The use of conjoint analysis to define the characteristics of women more likely to engage in specific practices should be used to develop tailored rather than standardised IVP interventions, and such interventions should be incorporated into clinical practice and women's health programmes.

    We have proposed that, unlike other HIV-vulnerable cell lineages, progenitor mast cells (prMCs), cultured in vitro from undifferentiated bone marrow-derived CD34(+) pluripotent progenitors (PPPs), are susceptible to infection during a limited period of their ontogeny. As infected prMCs mature in culture, they lose expression of viral chemokine coreceptors necessary for viral entry and develop into long-lived, latently infected mature tissue mast cells (MCs), resistant to new infection. In vivo recruitment of prMCs to different tissue compartments occurs in response to tissue injury, growth, and remodeling or allergic inflammation, allowing populations of circulating and potentially HIV-susceptible prMCs to spread persistent infection to diverse tissue compartments. In this report, we provide in vivo evidence to confirm this model by demonstrating that HIV-infected women have both circulating prMCs and placental tissue MCs (PLMCs) that harbor inducible infectious HIV even after highly active antiretroviral therapy (HAART) during pregnancy. Furthermore, infectious virus, capable of infecting alloactivated fetal cord blood mononuclear cells (CBMCs), could be induced in isolated latently infected PLMCs after weeks in culture in vitro. These data provide the first in vivo evidence that tissue MCs, developed from infected circulating prMCs, comprise a long-lived inducible reservoir of persistent HIV in infected persons during HAART.

    We have proposed that, unlike other HIV-vulnerable cell lineages, progenitor mast cells (prMCs), cultured in vitro from undifferentiated bone marrow–derived CD34+ pluripotent progenitors (PPPs), are susceptible to infection during a limited period of their ontogeny. As infected prMCs mature in culture, they lose expression of viral chemokine coreceptors necessary for viral entry and develop into long-lived, latently infected mature tissue mast cells (MCs), resistant to new infection. In vivo recruitment of prMCs to different tissue compartments occurs in response to tissue injury, growth, and remodeling or allergic inflammation, allowing populations of circulating and potentially HIV-susceptible prMCs to spread persistent infection to diverse tissue compartments. In this report, we provide in vivo evidence to confirm this model by demonstrating that HIV-infected women have both circulating prMCs and placental tissue MCs (PLMCs) that harbor inducible infectious HIV even after highly active antiretroviral therapy (HAART) during pregnancy.

    High adherence is critical for achieving clinical benefits of HIV antiretroviral therapy (ART) and particularly challenging for children. We conducted 35 qualitative interviews with caregivers of HIV-infected Ugandan children who were followed in a longitudinal study of real-time ART adherence monitoring; 18 participants had undetectable HIV RNA, while 17 had detectable virus. Interviews blinded to viral suppression status elicited information on adherence experiences, barriers and facilitators to adherence, and social support. Using an inductive content analytic approach, we identified ‘lack of resources,’ ‘Lazarus effect,’ ‘caregiver's sense of obligation and commitment,’ and ‘child's personal responsibility’ as categories of influence on adherence, and defined types of caregiver social support. Among children with viral suppression, high hopes for the child's future and ready access to private instrumental support appeared particularly important. These findings suggest clinical counseling should explore caregivers' views of their children's futures and ability to access support in overcoming adherence barriers. PMID:25323679

    Objective To determine the impact of self-reported marijuana use on the components of successful aging of human immunodeficiency virus-infected persons. Methods Cross-sectional study of 45- to 65-year-old HIV-infected subjects on anti-retroviral therapy >6 months with undetectable HIV-1 viral load. Successful aging was defined as absence of disease; adequate physical function; high Quality of Life (QOL) and social engagement. Clinical characteristics, physical function assessments, and QOL from short-form 36 (SF-36) were compared between groups defined by self-reported Recent Marijuana Use (RMU), adjusted for tobacco use, CD4+ T-cell count and time since HIV diagnosis, using logistic or linear regression for binary or continuous measures. Results 93 of 359 total subjects (26%) reported RMU. Demographically, patients reporting RMU had been diagnosed with HIV less recently (14 [13–16] vs 11 [10–12] years), reported smoking (48% vs 25%) and lower income (92% vs 80%) with greater prevalence than non-RMU patients; other demographics and clinical characteristics (age, CD4+ T-cell count) were similar. Gender, race/ethnicity, physical outcomes, physical function and disease burden were not significantly different. Patients reporting RMU demonstrated lower mental QOL and increased odds of low social engagement and un- or underemployment compared to non-users. Conclusions The negative association between RMU and mental or social QOL should be considered when assessing the success with which HIV patients reporting RMU are aging. PMID:25647530

    This paper explores motivational factors and barriers to sexual behaviour change among men receiving antiretroviral treatment (ART). Twenty in-depth interviews were undertaken with male patients enrolled at the African Medical and Research Foundation clinic in Africa's largest urban informal settlement, Kibera in Nairobi, Kenya. All participants experienced prolonged and severe illness prior to the initiation of ART. Fear of symptom relapse was the main trigger for sexual behaviour change. Partner reduction was reported as a first option for behaviour change since this decision could be made by the individual. Condom use was perceived as more difficult as it had to be negotiated with female partners. Cultural norms regarding expectations for reproduction and marriage were not supportive of sexual risk-reduction strategies. Thus, local sociocultural contexts of HIV-infected people must be incorporated into the contextual adaptation and design of ART programmes and services as they have an over-riding influence on sexual behaviour and programme effectiveness. Also, HIV-prevention interventions need to address both personal, micro- and macro-level factors of behaviour to encourage individuals to take on sexual risk-reduction strategies. In order to achieve the anticipated preventive effect of ART, these issues are important for the donor community and policy-makers, who are the major providers of ART programme support within weak health systems in sub-Saharan Africa.

    Background Little is known about the epidemiology on human papillomavirus (HPV) infection among HIV-infected men in Korea. The objective of this study was to determine the prevalence, genotype distribution and risk factors associated with anal HPV infection among HIV-infected men in Korea. Methods A single-center cross-sectional study was conducted with HIV-infected men in Korea. Participants completed a detailed sexual behavior risk factor questionnaire. Anal samples were collected for cytology and HPV genotyping. Factors associated with anal HPV infection were assessed using multivariable logistic regression, stratifying by sexual behaviour. Results A total of 201 HIV-infected men were included in the study: 133 were from men who have sex with men (MSM) and 68 from men who have sex with women (MSW). Any anal HPV infection was detected in 82.7% of HIV-infected MSM and in 51.5% of HIV- infected MSW (P < 0.001). High-risk HPV (HR-HPV) prevalence was higher among MSM (47.4%) than MSW (25.0%; P = 0.002). The HR-HPV types identified most frequently were HPV 16 (11%), HPV 18 (9.9%), and HPV 58 (5%) in MSM, and HPV 58(11%) and HPV 16 (8.9%) in MSW. Prevalence of any HPV types in 9-valent vaccine types was higher among MSM than MSW (47.4% vs 22.1%. P = 0.001). Abnormal anal cytology was more commonly detected in MSM than MSW (42.9% vs.19.1%, P < 0.001). In HIV-infected MSM, higher number of lifetime male sex partners was significantly associated with any anal HPV infection, but age was a significant risk factor associated with anal HR-HPV infection. Conclusion Anal HPV infection was highly prevalent in HIV-infected MSM in Korea, and also commonly found in HIV-infected MSW. In HIV-infected MSM, the significant risk factor for being infected with any HPV infection was lifetime number of male sexual partners, and with anal oncogenic HPV infection was age. PMID:27548632

    Background Cardiac involvement in HIV infected children has been frequently reported, but whether this is due to HIV infection itself or to antiretroviral treatment (ART) is unknown. Methods This cross sectional study involved 114 vertically-acquired HIV-infected (56 ART-naive, 58 ART-exposed) and 51 healthy children in Jakarta, Indonesia. Echocardiography was performed to measure dimensions of the left ventricle (LV) and systolic functions. We applied general linear modeling to evaluate the associations between HIV infection/treatment status and cardiac parameters with further adjustment for potential confounders or explanatory variables. Findings are presented as (adjusted) mean differences between each of the two HIV groups and healthy children, with 95% confidence intervals and p values. Results Compared to healthy children, ART-naïve HIV-infected children did not show significant differences in age-and-height adjusted cardiac dimensions apart from larger LV internal diameter (difference 2.0 mm, 95%CI 0.2 to 3.7), whereas ART exposed HIV infection showed thicker LV posterior walls (difference = 1.1 mm, 95%CI 0.5 to 1.6), larger LV internal diameter (difference = 1.7 mm, 95%CI 0.2 to 3.2) and higher LV mass (difference = 14.0 g, 7.4 to 20.5). With respect to systolic function, reduced LV ejection fraction was seen in both ART-naïve HIV infected (adjusted difference = -6.7%, -11.4 to -2.0) and, to a lesser extent, in ART-exposed HIV infected children (difference = -4.5%, -8.5 to -0.4). Inflammation level seemed to be involved in most associations in ART-exposed HIV-infected, but few, if any, for decreased function in the ART-naive ones, whereas lower hemoglobin appeared to partially mediate chamber dilation in both groups and reduced function, mainly in ART-exposed children. Conclusions ART-naive HIV infected children have a substantial decrease in cardiac systolic function, whereas the ART-exposed have thicker ventricular walls with larger internal diameter

    Although HIV-prevalence and fertility rates in sub-Saharan Africa are among the highest in the world, little is known about how HIV infection affects the fertility preferences of men and women in the region. A quasi-experimental design and in-depth interviews conducted in rural Malawi are employed to examine how and through what pathways learning that one is HIV positive alters a person’s childbearing desires. Among rural Malawians, particularly men, the desire to have more children decreases after receiving a positive HIV-test result. The motivations underlying this effect are greatly influenced by gender: women fear the physical health consequences of HIV-positive pregnancies and childbearing, whereas men see childbearing as futile because they anticipate their own early death and the deaths of their future children. Considerable ambivalence remains, nevertheless, particularly among women who strategize to live normal lives in spite of their infection, but whose definitions of “normal” vary. PMID:21151844

    Tenofovir disoproxil fumarate (TDF) is approved by the Food and Drug Administration for use in children ages 2 years and older and is recommended by the World Health Organization for use as a preferred first-line nucleotide reverse transcriptase inhibitor in adults and adolescents ages 10 years and older. The simplicity of once daily dosing, few metabolic side effects and efficacy against hepatitis B virus make TDF suitable for use in a large scale program. Unlike thymidine analoge nucleoside reverse transcriptase inhibitors (NRTIs); tenofovir does not induce multi-NRTI resistance mutations, so more NRTI options are available for future second-line-regimens. Fixed-dose combinations of TDF with other ARVs as a single tablet regimen are now widely available for adults and adolescents, but none are available for young children. Current information on TDF including the pharmacokinetics, safety and tolerability in children and adolescents was reviewed. A dosing regimen according to body-weight-band has been established for pediatric use. Safety concerns of TDF mainly relate to its effects on renal function and bone mineral density. Regular monitoring of renal function in high-risk patients, including those on other nephrotoxic drugs, may be warranted to detect adverse renal effects. Long-term-data on renal and bone outcomes among HIV-infected children is needed. Lessons learned from clinical studies will help clinicians balance the risks and benefits of TDF and design appropriate antiretroviral regimens for children in different circumstances. PMID:25247583

    Although human papillomavirus (HPV) infections are common in HIV-infected adults, little is known about children. Our objective was to examine the prevalence of and risks for HPV of the oral mucosal and external genital areas in nonsexually active (NSA) perinatally (P) HIV+ children and compare with HIV-exposed but uninfected (HEU) children. A convenience sample attending a pediatric clinic were enrolled. Samples for HPV were obtained from the oral and anogenital areas and tested for one of 37 HPV types. The mean age of the 48 PHIV+ children was 14.3±3.9 years vs. 6.2±4.8 for the 52 HEU (p<0.001). Of the 23 PHIV+ girls, 30.4% had anogenital and 17% had oral HPV, and of the 27 HEU girls, 2 (7.4%) anogenital and 0 had oral HPV. Of the boys, 4/23 (17.4%) and 1/25 (4%) PHIV+ had anogenital and oral HPV, respectively, and 3/24 (12.5%) and 1/25 (4%) HEU had anogenital and oral HPV, respectively. Rates of HPV did not differ by age among the PHIV+, whereas older HEU were more likely to have HPV than younger HEU (p=0.07). This large age gap precluded statistical comparison by HIV status. The presence of HPV in NSA PHIV+ children may have implications regarding HPV vaccination efficacy. PMID:24460009

    `The gradual reduction in the incidence of AIDS among men who have sex with men has not occurred in the youngest age group; on the contrary, it is growing. This paper examines the vulnerabilities of adolescent males at risk of HIV infection. This is a qualitative study conducted through interviews with HIV positive young men undergoing treatment, whose diagnosis was made during adolescence. The interviews were recorded and transcribed in full. They were analyzed by intensive reading, classified by issues, and interpreted from a hermeneutic-dialectic perspective in dialogue with the literature. We interviewed 16 young men whose diagnosis occurred between the ages of 11 and 19 and for all of them the method of HIV transmission was sexual; 12 of the men were homosexual and 4 were heterosexual. It was evident that vulnerable situations included disbelief in the possibility of contamination, subjection to sex, homophobia and commercial sexual exploitation. This study demonstrates the importance of the formulation of public policies on sexual and reproductive health, which include adolescents and young men. These policies should embody the perspective of masculinity in all its widest aspects, as well as actions in favor of sexual diversity. PMID:26132259

    Approximately 34 million people were living with human immunodeficiency virus (HIV-1) at the end of 2011. From the last two decades, researchers are actively involved in the development of an effective HIV-1 treatment, but the results intended are still doubtful about the eradication of HIV. The HIV-1 virus has gone from being an “inherently untreatable” infectious agent to the one liable to be affected by a range of approved therapies. Candidate microbicides have been developed to target specific steps in the process of viral transmission. Microbicides are self-administered agents that can be applied to vaginal or rectal mucosal surfaces with the aim of preventing, or reducing, the transmission of sexually transmitted infections (STIs) including HIV-1. The development of efficient, widely available, and low-cost microbicides to prevent sexually transmitted HIV infections should be given high priority. In this review, we studied the various forms of microbicides, their mechanism of action, and their abundant approaches to control the transmission of sexually transmitted infections (STIs).

    In pathogenic simian immunodeficiency virus (SIV) and human immunodeficiency virus (HIV) infections, the translocation of microbial products from the gastrointestinal (GI) tract to portal and systemic circulation has been proposed as a major driver of the chronic immune activation that is associated with disease progression. Consistently, microbial translocation is not present in nonpathogenic SIV infections of natural host species. In vivo studies demonstrated that HIV/SIV-associated microbial translocation results from a series of immunopathological events occurring at the GI mucosa: (i) early and severe mucosal CD4(+) depletion, (ii) mucosal immune hyperactivation/persistent inflammation; (iii) damage to the integrity of the intestinal epithelium with enterocyte apoptosis and tight junction disruption; and (iv) subverted the gut microbiome, with a predominance of opportunistic bacteria. Direct in situ evidence of microbial translocation has been provided for SIV-infected rhesus macaques showing translocated microbial products in the intestinal lamina propria and distant sites. While the mechanisms by which microbial translocation causes immune activation remain controversial, a key pathogenic event appears to be innate immunity activation via Toll-like receptors and other pathogen recognition receptors. Accumulating clinical observations suggest that microbial translocation might affect HIV disease progression, response to therapy, and non-AIDS comorbidities. Given its detrimental effect on overall immunity, several interventions to prevent/block microbial translocation are currently under investigation as novel therapeutic agents for HIV/AIDS.

    As part of a military universal HIV screening program, 442 men were assessed for the presence of DSM-III-R defined psychiatric disorders and symptoms of anxiety and depression after notification of HIV seroconversion. Of them, 84.4% were in the earliest, asymptomatic stages of disease at the time of interview (96% did not have AIDS). The Structured Clinical Interview for DSM-III-R and Structured Interview Guide for the Hamilton Anxiety and Depression Scales were used. Relevant comparisons were made to Epidemiologic Catchment Area prevalence data. HIV seropositive men were more likely than age-matched men in the community to have current diagnoses of major depression (ages 18-44) and anxiety disorders (ages 25-44). Higher lifetime rates of major depression and alcohol use disorder, and high current prevalence of sexual dysfunction (21.7%) were noted. We conclude that men who become HIV seropositive have high rates of mood and substance use disorders prior to knowledge of seroconversion, and that early in the course of HIV infection men are at risk for developing major depression, anxiety disorders, and disorders of sexual desire.

    G-protein-coupled receptors (GPCRs) are cell membrane protein receptors that transduce signals across the cell membrane and are important targets for therapeutic interventions. As members of the GPCR superfamily, chemokine receptors such as CXCR4 play critical roles in normal physiology as well as the pathology of many human diseases including cancer, inflammation, autoimmune diseases, and human immunodeficiency virus (HIV) infection. Here we report the discovery and study of a novel peptide ligand of CXCR4 using D-amino acids and bivalent ligand approach. This peptide, DV1-K-(DV3), shows very high affinity for CXCR4 with an IC50 of 4 nM in anti-CXCR4 monoclonal antibody (mAb) 12G5 competitive assay, which is more potent than full length natural ligand SDF-1α, even though the peptide is less than half of the number of residues of SDF-1α. This peptide can block the calcium influx stimulated by SDF-1α and inhibit cancer cell migration in vitro via CXCR4, thus functioning as a CXCR4 antagonist. Furthermore, DV1-K-(DV3) peptide displayed anti-HIV activity by inhibiting HIV-1 infection mediated by CXCR4. With its high receptor affinity and stability from D-amino acids, this peptide may be a new probe of CXCR4 functions in physiology and pathology and promising lead for therapeutic development.
