    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.

    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

    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

    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

    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

    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

    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.

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.

    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

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.

    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.

    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 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

    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.

    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.

    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.

    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

  16. 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

    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.

    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.

    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.

    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.

    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

    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

    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

    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.

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

    PubMed

    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

    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.

  2. The stochastic dance of early HIV infection

    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).

    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

    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

    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.

    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

    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

    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

    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

    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

    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.

    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).

    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

    '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.

    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.

    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

    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

    Objective The objectives of this study were to determine the rate of testosterone replacement therapy (TRT) initiation, TRT predictors and associated monitoring in HIV-infected men. Design A multisite cohort study. Methods We examined TRT initiation rates and monitoring among adult HIV-infected men in routine care at seven sites in the Centers for AIDS Research (CFAR) Network of Integrated Clinical Systems (CNICS) from 1996 to 2011. We determined TRT predictors using Cox regression modelling. 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

    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 mid-life, 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.

    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.

    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.

    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

    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

    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

    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

    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.

    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.

    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

    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.

    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

    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 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.

    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.

    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
