Secondary infectious diseases contribute substantially to morbidity and mortality of people infected with human immunodeficiency virus (HIV). The authors developed comprehensive, practical recommendations for prevention of infectious complications in HIV-infected people. Recommendations are concerned with the pathogens that are more common or more severe in HIV-infected people. Several infectious complications can be prevented by avoiding ingestion of contaminated food or water. Zoonoses can be prevented by precautions to be taken in contacts with animals. The risk of several fungal diseases can be reduced if activities likely to lead to inhalation of spores are avoided. HIV-infected people should be advised how to lower adverse health effects of travel, especially international travel. The potential for infectious complications of sexual activity and illicit drug use should be stressed, and recommendations to reduce the risk are discussed. Recommendations for use of vaccines in HIV-infected people are reviewed. Blood CD4+ lymphocyte concentrations, tuberculin skin testing, Toxoplasma serology, and sexually transmitted disease screening should be performed in certain subsets of HIV-infected people. Guidelines for chemoprophylaxis against Pneumocystis carinii and tuberculosis are presented. Recent data suggest that intravenous immunoglobulin therapy may prevent bacterial infections in HIV-infected children. PMID:1910184

Objective: To describe the prevalence of neurocognitive impairment (NCI) among early diagnosed and managed HIV-infected persons (HIV+) compared to HIV-negative controls. Methods: We performed a cross-sectional study among 200 HIV+ and 50 matched HIV-uninfected (HIV−) military beneficiaries. HIV+ patients were categorized as earlier (<6 years of HIV, no AIDS-defining conditions, and CD4 nadir >200 cells/mm3) or later stage patients (n = 100 in each group); both groups were diagnosed early and had access to care. NCI was diagnosed using a comprehensive battery of standardized neuropsychological tests. Results: HIV+ patients had a median age of 36 years, 91% were seroconverters (median window of 1.2 years), had a median duration of HIV of 5 years, had a CD4 nadir of 319, had current CD4 of 546 cells/mm3, and 64% were on highly active antiretroviral therapy (initiated 1.3 years after diagnosis at a median CD4 of 333 cells/mm3). NCI was diagnosed among 38 (19%, 95% confidence interval 14%–25%) HIV+ patients, with a similar prevalence of NCI among earlier and later stage patients (18% vs 20%, p = 0.72). The prevalence of NCI among HIV+ patients was similar to HIV− patients. Conclusions: HIV+ patients diagnosed and managed early during the course of HIV infection had a low prevalence of NCI, comparable to matched HIV-uninfected persons. Early recognition and management of HIV infection may be important in limiting neurocognitive impairment. PMID:23303852

The incidence of certain non-AIDS-defining cancers (NADCs) 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. We followed 12 872 HIV-infected Kaiser Permanente members whose complete ART history was known for incident cancers between 1996 and 2008. Cancers, identified from Surveillance, Epidemiology, and End Results (SEER)-based cancer registries, were grouped as ADCs, infection-related NADCs, or infection-unrelated NADCs. We also evaluated the most common individual cancer types. Rate ratios for ART use (yes/no) and cumulative duration of any ART, protease inhibitor, and nonnucleotide reverse transcriptase inhibitor (NNRTI) therapy were obtained from Poisson models adjusting for demographics, pretreatment or recent CD4 cell count and HIV RNA levels, years known HIV-infected, prior antiretroviral use, HIV risk, smoking, alcohol/drug abuse, overweight/obesity, and calendar year. The cohort experienced 32 368 person-years of ART, 21 249 person-years of protease inhibitor therapy, and 15 643 person-years of NNRTI therapy. The mean follow-up duration was 4.5 years. ADC rates decrease with increased duration of ART use [rate ratio per year = 0.61 (95% confidence interval 0.56-0.66)]; the effect was similar by therapy class. ART, protease inhibitor, or NNRTI therapy duration was not associated with infection-related or infection-unrelated NADC [rate ratio per year ART = 1.00 (0.91-1.11) and 0.96 (0.90-1.01), respectively], except a higher anal cancer risk with longer protease inhibitor therapy [rate ratio per year = 1.16 (1.02-1.31)]. No therapy class-specific effect was found for ADC. ART exposure was generally not associated with NADC risk, except for long-term use of protease inhibitor, which might be associated with increased anal cancer risk.

Hepatitis C virus infection in HIV-infected patients.

PubMed

Sulkowski, Mark S

2007-10-01

The hepatitis C virus (HCV) is a spherical enveloped RNA virus of the Flaviviridae family, classified within the Hepacivirus genus. Since its discovery in 1989, HCV has been recognized as a major cause of chronic hepatitis and hepatic fibrosis that progresses in some patients to cirrhosis and hepatocellular carcinoma. In the United States, approximately 4 million people have been infected with HCV, and 10,000 HCVrelated deaths occur each year. Due to shared routes of transmission, HCV and HIV co-infection are common, affecting approximately one third of all HIV-infected persons in the United States. In addition, HIV co-infection is associated with higher HCV RNA viral load and a more rapid progression of HCV-related liver disease, leading to an increased risk of cirrhosis. HCV infection may also impact the course and management of HIV disease, particularly by increasing the risk of antiretroviral drug-induced hepatotoxicity. Thus, chronic HCV infection acts as an opportunistic disease in HIV-infected persons because the incidence of infection is increased and the natural history of HCV infection is accelerated in co-infected persons. Strategies to prevent primary HCV infection and to modify the progression of HCV-related liver disease are urgently needed among HIV/HCV co-infected individuals.

Background Foreign-born, HIV-infected persons are at risk for sub-clinical parasitic infections acquired in their countries of origin. The long-term consequences of co-infections can be severe, yet few data exist on parasitic infection prevalence in this population. Methodology/Principal Findings This cross-sectional study evaluated 128 foreign-born persons at one HIV clinic. We performed stool studies and serologic testing for strongyloidiasis, schistosomiasis, filarial infection, and Chagas disease based on the patient's country of birth. Eosinophilia and symptoms were examined as predictors of helminthic infection. Of the 128 participants, 86 (67%) were male, and the median age was 40 years; 70 were Mexican/Latin American, 40 African, and 18 from other countries or regions. Strongyloides stercoralis antibodies were detected in 33/128 (26%) individuals. Of the 52 persons from schistosomiasis-endemic countries, 15 (29%) had antibodies to schistosome antigens; 7 (47%) had antibodies to S. haematobium, 5 (33%) to S. mansoni, and 3 (20%) to both species. Stool ova and parasite studies detected helminths in 5/85 (6%) persons. None of the patients tested had evidence of Chagas disease (n = 77) or filarial infection (n = 52). Eosinophilia >400 cells/mm3 was associated with a positive schistosome antibody test (OR 4.5, 95% CI 1.1–19.0). The only symptom significantly associated with strongyloidiasis was weight loss (OR 3.1, 95% CI 1.4–7.2). Conclusions/Significance Given the high prevalence of certain helminths and the potential lack of suggestive symptoms and signs, selected screening for strongyloidiasis and schistosomiasis or use of empiric antiparasitic therapy may be appropriate among foreign-born, HIV-infected patients. Identifying and treating helminth infections could prevent long-term complications. PMID:21532747

We infected 11 HIV-seropositive volunteers whose CD4(+) cell counts were >350 cells/ microL (7 of whom were receiving antiretrovirals) with Haemophilus ducreyi. The papule and pustule formation rates were similar to those observed in HIV-seronegative historical control subjects. No subject experienced a sustained change in CD4(+) cell count or HIV RNA level. The cellular infiltrate in biopsy samples obtained from the HIV-seropositive and HIV-seronegative subjects did not differ with respect to the percentage of leukocytes, neutrophils, macrophages, or T cells. The CD4(+):CD8(+) cell ratio in biopsy samples from the HIV-seropositive subjects was 1:3, the inverse of the ratio seen in the HIV-seronegative subjects (P<.0001). Although CD4(+) cells proliferated in lesions, in situ hybridization and reverse-transcription polymerase chain reaction for HIV RNA was negative. We conclude that experimental infection in HIV-seropositive persons is clinically similar to infection in HIV-seronegative persons and does not cause local or augment systemic viral replication. Thus, prompt treatment of chancroid may abrogate increases in viral replication associated with natural disease.

Lactobacillus sp. are commensal organisms that are increasingly reported to cause invasive infections among immunosuppressed persons. However, few data exist regarding the occurrence and risk factors of these infections among HIV-infected persons. Further, the safety of products that contain lactobacilli (e.g. probiotics) in certain populations, including those with HIV/AIDS, is unclear. We report a case of Lactobacillus acidophilus bacteraemia in a patient with AIDS temporally related to excessive consumption of probiotic-enriched yogurt, and provide a comprehensive review of the literature of Lactobacillus sp. infections among HIV-infected persons. © The Author(s) 2015.

Non-AIDS-defining cancers are a rising health concern among HIV-infected patients. Cancer screening is now an important component of health maintenance in HIV clinical practice. The decision to screen an HIV-infected patient for cancer should include an assessment of individualized risk for the particular cancer, life expectancy, and the harms and benefits associated with the screening test and its potential outcome. HIV-infected patients are at enhanced risk of several cancers compared to the general population; anal cancer, hepatocellular carcinoma, Hodgkin's lymphoma, and lung cancer all have good evidence demonstrating an enhanced risk in HIV-infected persons. A number of cancer screening interventions have shown benefit for specific cancers in the general population, but data on the application of these tests to HIV-infected persons are limited. Here we review the epidemiology and background literature relating to cancer screening interventions in HIV-infected persons. We then use these data to inform a conceptual model for evaluating HIV-infected patients for cancer screening.

Objectives The causes of disability among chronic methamphetamine (MA) users are multifactorial. The current study examined the additive adverse impact of human immunodeficiency virus (HIV) infection, a common comorbidity in MA users, on functional dependence. Methods A large cohort of participants (N=798) stratified by lifetime MA dependence diagnoses (i.e., MA+ or MA−) and HIV serostatus (i.e., HIV+ or HIV−) underwent comprehensive baseline neuromedical, neuropsychiatric, and functional research evaluations, including assessment of neurocognitive symptoms in daily life, instrumental and basic activities of daily living, and employment status. Results Independent, additive effects of MA and HIV were observed across all measures of functional dependence, independent of other demographic, psychiatric, and substance use factors. The prevalence of global functional dependence increased in the expected stepwise fashion across the cohort, with the lowest rates in the MA−/HIV− group (29%) and the highest rates in the MA+/HIV+ sample (69%). The impact of HIV on MA-associated functional dependence was moderated by nadir CD4 count, such that MA use was associated with greater disability among those HIV-infected persons with higher, but not lower nadir CD4. Within the MA+/HIV+ cohort, functional dependence was reliably associated with neurocognitive impairment, lower cognitive reserve, polysubstance use, and major depressive disorder. Conclusions HIV infection confers an increased concurrent risk of MA-associated disability, particularly among HIV-infected persons without histories of immune compromise. Directed referrals, earlier HIV treatment, and compensatory strategies aimed at counteracting the effects of low cognitive reserve, neurocognitive impairment, and psychiatric comorbidities on functional dependence in MA+/HIV+ individuals may be warranted.

2016-01-01

Increasing rates of HIV have been observed in women, African Americans, and Hispanics, particularly those residing in rural areas of the United States. Although cardiovascular (CV) complications in patients infected with human immunodeficiency virus (HIV) have significantly decreased following the introduction of antiretroviral therapy on a global scale, in many rural areas, residents face geographic, social, and cultural barriers that result in decreased access to care. Despite the advancements to combat the disease, many patients in these medically underserved areas are not linked to care, and fewer than half achieve viral suppression. Databases were systematically searched for peer-reviewed publications reporting infectious and non-infectious etiologies of cardiovascular disease in HIV-infected patients. Relevant articles cited in the retrieved publications were also reviewed for inclusion. A variety of outcomes studies and literature reviews were included in the analysis. Relevant literature discussed the manifestations, diagnosis, treatment, and outcomes of infectious and non-infectious etiologies of cardiovascular disease in HIV-infected patients. In these medically underserved areas, it is vital that clinicians are knowledgeable in the manifestations, diagnosis, and treatment of CV complications in patients with untreated HIV. This review summarizes the epidemiology and causes of CV complications associated with untreated HIV and provide recommendations for management of these complications.

Prevalence and correlates of fatigue among persons with HIV infection.

To describe prevalence of fatigue and its correlates among persons with HIV infection, we abstracted medical records of 13,768 persons in care for HIV in >100 US clinics. The prevalence of fatigue (defined as fatigue, malaise, or weakness that was the primary reason for a medical visit, was persistent, or was severe enough to preclude work) was 37%. Fatigue was more common among persons with clinical AIDS (adjusted odds ratio [AOR] 1.3, CI 1.1-1.5); depression (AOR 2.4, CI 2.1-2.7); and hemoglobin concentrations <8, 8-10, and 10-12 g/dL (AORs 3.3 [CI 2.4-4.6], 2.7 [CI 2.2-3.2], and 1.5 [CI 1.3-1.7], respectively). Fatigue was not associated with viral load or CD4 cell count <200/microl. Fatigue cannot be viewed solely as a constitutional symptom of progressive HIV disease. Physicians should seek underlying, treatable causes for fatigue such as depression and anemia and treat these conditions when they are found.

The tuberculin skin test (TST), T-Spot.TB (T-Spot) and QuantiFERON-TB Gold-In Tube (QFT) were compared in diagnosing latent tuberculosis infection (LTBI) among human immunodeficiency virus (HIV)-infected persons. Human immunodeficiency virus-infected persons without previous history of tuberculosis or LTBI were simultaneously tested by TST, T-Spot and QFT annually and followed up for tuberculosis. Among 110 HIV-infected subjects with 85% previous TST screening coverage, 75% on anti-retroviral therapy, well-preserved median CD4 count (414/μL) and low median viral load (<75/μL), baseline TST, T-Spot and QFT were positive in 5.5%, 5.6% and 4.9%, respectively, with almost complete discordance of positive results. Among 91 (83%), 66 (60%) and 26 (24%) subjects successfully undergoing the first, second and third annual retesting, TST, T-Spot and QFT were, respectively, positive in 11/123 (8.9%), 13/173 (7.5%) and 21/182 (11.5%) on retesting, with similar discordance of positive results. There was no significant association with the concurrent CD4 count or viral load. Conversion occurred in 11/123 (8.9%), 8/160 (5.0%) and 18/168 (10.7%) of TST, T-Spot and QFT, respectively, and none was associated with changes in CD4 count or viral load. More than half of the positive T-SPOT and QFT results reverted to negative on follow-up. None of these tests picked up the single case of culture-confirmed tuberculosis observed after 798 person-years of follow-up. Major discordance in positive results, high reversion rates and low tuberculosis incidence among test-positive subjects cast serious doubt on the utility of the currently available LTBI tests in the annual screening of HIV-infected persons in an intermediate tuberculosis burden area. © 2016 Asian Pacific Society of Respirology.

In the United States, an estimated 7% of new diagnoses of human immunodeficiency virus (HIV) infection in 2012 were attributed to injection drug use, and an additional 3% to male-to-male sexual contact and injection drug use. To monitor HIV prevalence and behaviors associated with HIV risk and prevention among persons who inject drugs (PWID), CDC's National HIV Behavioral Surveillance (NHBS) system conducts interviews and HIV testing in selected cities. This report summarizes HIV prevalence and behaviors among PWID interviewed and tested in 20 cities in 2012. Of the 10,002 PWID tested, 11% had a positive HIV test result. Among 9,425 PWID included in the behavioral analysis, 30% receptively shared syringes, 70% had vaginal sex without a condom, 25% had heterosexual anal sex without a condom, and 5% of males had male-to-male sexual contact without a condom in the previous 12 months. Fifty-one percent of PWID included in the behavioral analysis had been tested for HIV, 25% participated in an HIV behavioral intervention, and 39% participated in substance abuse treatment in the previous 12 months. Additional efforts are needed to reduce risk behaviors and increase access to HIV testing, drug treatment, and other HIV prevention programs to further reduce HIV infections among PWID.

Pneumococcal pneumonia: clinical features, diagnosis and management in HIV-infected and HIV noninfected patients.

In this review, we focus on the clinical features, diagnosis and management of pneumococcal pneumonia in HIV-infected and noninfected patients, with particular attention to the most recent advances in this area. Classical clinical features are found in young adults, whereas atypical forms occur in immunocompromised patients including HIV-infected individuals. Bacteremic pneumococcal pneumonia is more frequently observed in HIV-infected and also in low-risk patients, according to the Pneumonia Severity Index (PSI). Pneumococcal pneumonia diagnostic process includes physical examination, radiologic findings and microbiologic diagnosis. However, etiologic diagnosis using traditional culture methods is difficult to obtain. In this setting, urinary antigen test, which recognizes Streptococcus pneumoniae cell wall C-polysaccharide, increases the probability of etiologic diagnosis. A correct management approach is crucial in reducing pneumococcal pneumonia mortality. The use of the PSI helps clinicians in deciding between inpatient and outpatient management in immunocompetent individuals, according to Infectious Diseases Society of America (IDSA)-American Thoracic Society (ATS) guidelines. Recent findings support PSI utility also in HIV-infected patients. Recently, efficacy of pneumococcal vaccine in reducing pneumococcal disease incidence has been evidenced in both HIV-infected and noninfected individuals. Rapid diagnosis and correct management together with implementation of preventive measures are crucial in order to reduce pneumococcal pneumonia related incidence and mortality in HIV-infected and noninfected patients.

People living with human immunodeficiency virus (HIV) are living longer since the advent of effective combined antiretroviral therapy (cART). While cART substantially decreases the risk of developing some cancers, HIV-infected individuals remain at high risk for Kaposi sarcoma, lymphoma and several solid tumors. Currently HIV-infected patients represent an aging group, and malignancies have become a leading cause of morbidity and mortality. Tailored cancer-prevention strategies are needed for this population. In this review we describe the etiologic agents and pathogenesis of common malignancies in the setting of HIV, as well as current evidence for cancer prevention strategies and screening programs.

Lung Cancer in HIV Infection

Mani, Deepthi; Haigentz, Missak; Aboulafia, David M

2011-01-01

Lung cancer is the most prevalent non-AIDS-defining malignancy in the HAART era. Smoking plays a significant role in the development of HIV-associated lung cancer, but the cancer risk is 2–4 times greater in HIV-infected persons than in the general population, even after adjusting for smoking intensity and duration. Lung cancer is typically diagnosed a decade or more earlier among HIV-infected persons (mean age, 46 years) compared to those without HIV infection. Adenocarcinoma is the commonest histological subtype, and the majority of patients are diagnosed with locally advanced or metastatic carcinoma. Since pulmonary infections are common among HIV-infected individuals, clinicians may not suspect lung cancer in this younger patient population. Surgery with curative intent remains the treatment of choice for early stage disease. Although there is increasing experience in using radiation and chemotherapy for HIV-infected patients who do not have surgical options, there is a need for prospective studies for this population frequently excluded from participating in cancer trials. Evidence-based treatments for smoking-cessation with demonstrated efficacy in the general population must be routinely incorporated into the care of HIV-positive smokers. PMID:21802373

Evaluation and Management of Dyslipidemia in Patients with HIV Infection

Green, Michael L

2002-01-01

OBJECTIVE Persons with HIV infection develop metabolic abnormalities related to their antiretroviral therapy and HIV infection itself. The objective of this study was to summarize the emerging evidence for the incidence, etiology, health risks, and treatment of dyslipidemias in HIV disease. DESIGN Systematic review of original research with quantitative synthesis. MAIN RESULTS Dyslipidemia is common in persons with HIV infection on highly active antiretroviral therapy (HAART), but methodologic differences between studies preclude precise estimates of prevalence and incidence. The typical pattern includes elevated total cholesterol, low-density lipoprotein cholesterol, and triglycerides, which may be markedly elevated. The dyslipidemia may be associated with lipodystrophy, insulin resistance, and, rarely, frank diabetes mellitus. Exposure to protease inhibitors (PIs) is associated with this entire range of metabolic abnormalities. PI-naïve patients on nucleoside reverse transcriptase inhibitors (NRTIs) may develop lipodystrophy, insulin resistance, hypercholesterolemia, and possibly modest elevations in triglycerides but not severe hypertriglyceridemia, which appears to be linked to PIs alone. Most studies have not found an association between CD4 lymphocyte count or HIV viral load and lipid abnormalities. The pathogenesis is incompletely understood and appears to be multifactorial. There are insufficient data to definitively support an increased coronary heart disease risk in patients with HIV-related dyslipidemia. However, some of the same metabolic abnormalities remain firmly established risk factors in other populations. Patients on HAART with severe hypertriglyceridemia may develop pancreatitis or other manifestations of the chylomicronemia syndrome. Some of the metabolic derangements (particularly hypertriglyceridemia) may improve upon replacing a PI with a non-nucleoside reverse transcriptase inhibitor. The limited experience suggests that fibrates

Objective We identified correlates of perceived risk of HIV infection among persons who inject drugs (PWID) in Tijuana. Materials and methods PWID ≥18 years of age who injected drugs in the past month were recruited between 2006–2007 and completed risk assessment interviews and serologic testing for HIV, syphilis, and tuberculosis. Logistic regression was used to determine factors associated with high-perceived risk of HIV infection. Results Among 974 PWID, HIV prevalence was 4.4%; 45.0% of participants perceived themselves to be more likely to become HIV infected relative to other PWID in Tijuana. Participants who reported high-perceived risk of HIV infection participated in high-risk behaviors such as injecting with used syringes, transactional sex, and were less likely to have had an HIV test. Conclusions Recognition of HIV infection risk was associated with high risk behaviors and markers of vulnerability. Findings support efforts to encourage HIV testing and access to health care for this vulnerable population. PMID:26545125

An evaluation of the effects of HIV infection on neurocognition over time is important for understanding disease progression. Changes in cognitive function can be evaluated longitudinally using neuropsychological testing at repeated intervals. The assessment of change over time, however, is complicated by the potentially confounding influence of learning on repeated test administrations, often referred to as practice effect. In this study, we present data on testing of persons with or without HIV infection on a battery administered at study baseline and repeated one year later. Results suggest that practice effects may be diminished in persons with HIV infection compared to without it. This appears to be true even among those with relatively intact immune functioning as measured by CD4 count. PMID:27739034

2017-02-01

Transgender persons are at high risk for HIV infection, but prevention efforts specifically targeting these people have been minimal. Part of the challenge of HIV prevention for transgender populations is that numerous individual, interpersonal, social, and structural factors contribute to their risk. By combining HIV prevention services with complementary medical, legal, and psychosocial services, transgender persons' HIV risk behaviors, risk determinants, and overall health can be affected simultaneously. For maximum health impact, comprehensive HIV prevention for transgender persons warrants efforts targeted to various impact levels-socioeconomic factors, decision-making contexts, long-lasting protections, clinical interventions, and counseling and education. We present current HIV prevention efforts that reach transgender persons and present others for future consideration.

Background: Published death rates for persons with HIV have not distinguished deaths due to HIV from deaths due to other causes. Cause-specific death rates would allow better assessment of care needs. Methods: Using data reported to the US national HIV surveillance system, we examined a) associations between selected decedent characteristics and causes of death during 2007-2011, b) trends in rates of death due to underlying causes among persons with AIDS during 1990-2011, and among all persons with diagnosed HIV infection (with or without AIDS) during 2000-2011. Results: During 2007-2011, non-HIV-attributable causes of death with the highest rates per 1,000 person-years were heart disease (2.0), non-AIDS cancers other than lung cancer (1.4), and accidents (0.8). During 1990-2011, among persons with AIDS, the annual rate of death due to HIV-attributable causes decreased by 89% (from 122.0 to 13.2), and the rate due to non-HIV-attributable-causes decreased by 57% (from 20.0 to 8.6), while the percentage of deaths caused by non-HIV-attributable causes increased from 11% to 43%. During 2000-2011, among persons with HIV infection, the rate of death due to HIV-attributable causes decreased by 69% (from 26.4 to 8.3), and the rate due to non-HIV-attributable causes decreased by 28% (from 10.5 to 7.6), while the percentage of deaths caused by non-HIV-attributable causes increased from 25% to 48%. Conclusion: Among HIV-infected persons, as rates of death due to HIV-attributable causes decreased, rates due to non-HIV-attributable causes also decreased, but the percentages of deaths due to non-HIV-attributable causes, such as heart disease and non-AIDS cancers increased.

Published death rates for persons with HIV have not distinguished deaths due to HIV from deaths due to other causes. Cause-specific death rates would allow better assessment of care needs. Using data reported to the US national HIV surveillance system, we examined a) associations between selected decedent characteristics and causes of death during 2007-2011, b) trends in rates of death due to underlying causes among persons with AIDS during 1990-2011, and among all persons with diagnosed HIV infection (with or without AIDS) during 2000-2011. During 2007-2011, non-HIV-attributable causes of death with the highest rates per 1,000 person-years were heart disease (2.0), non-AIDS cancers other than lung cancer (1.4), and accidents (0.8). During 1990-2011, among persons with AIDS, the annual rate of death due to HIV-attributable causes decreased by 89% (from 122.0 to 13.2), and the rate due to non-HIV-attributable-causes decreased by 57% (from 20.0 to 8.6), while the percentage of deaths caused by non-HIV-attributable causes increased from 11% to 43%. During 2000-2011, among persons with HIV infection, the rate of death due to HIV-attributable causes decreased by 69% (from 26.4 to 8.3), and the rate due to non-HIV-attributable causes decreased by 28% (from 10.5 to 7.6), while the percentage of deaths caused by non-HIV-attributable causes increased from 25% to 48%. Among HIV-infected persons, as rates of death due to HIV-attributable causes decreased, rates due to non-HIV-attributable causes also decreased, but the percentages of deaths due to non-HIV-attributable causes, such as heart disease and non-AIDS cancers increased.

Vitamin D in HIV-Infected Patients

2013-01-01

Observational studies have noted very high rates of low 25(OH)D (vitamin D) levels in both the general and HIV-infected populations. In HIV-infected patients, low 25(OH)D levels are likely a combination of both traditional risk factors and HIV- and antiretroviral therapy-specific contributors. Because of this unique risk profile, HIV-infected persons may be at greater risk for low 25(OH)D levels and frank deficiency and/or may respond to standard repletion regimens differently than HIV-uninfected patients. Currently, the optimal repletion and maintenance dosing regimens for HIV-infected patients remain unknown, as do potential benefits of supplementation that may be unique to the HIV-infected population. This paper reviews data published on HIV infection and vitamin D health in adults over the last year. PMID:21647555

To achieve epidemic control of human immunodeficiency virus (HIV) infection, sub-Saharan African countries are striving to diagnose 90% of HIV infections, initiate and retain 90% of HIV-diagnosed persons on antiretroviral therapy (ART), and achieve viral load suppression* for 90% of ART recipients (90-90-90) (1). In Eswatini (formerly Swaziland), the country with the world's highest estimated HIV prevalence (27.2%), achieving 90-90-90 depends upon improving access to early ART for men and young adults with HIV infection, two groups with low ART coverage (1-3). Although community-based strategies test many men and young adults with HIV infection in Eswatini, fewer than one third of all persons who test positive in community settings enroll in HIV care within 6 months of diagnosis after receiving standard referral services (4,5). To evaluate the effectiveness of peer-delivered linkage case management † in improving early ART initiation for persons with HIV infection diagnosed in community settings in Eswatini, CDC analyzed data on 651 participants in CommLink, a community-based, mobile HIV-testing, point-of-diagnosis HIV care, and peer-delivered linkage case management demonstration project, and found that after diagnosis, 635 (98%) enrolled in care within a median of 5 days (interquartile range [IQR] = 2-8 days), and 541 (83%) initiated ART within a median of 6 days (IQR = 2-14 days), including 402 (74%) on the day of their first clinic visit (same-day ART). After expanding ART eligibility to all persons with HIV infection on October 1, 2016, 96% of 225 CommLink clients initiated ART, including 87% at their first clinic visit. Compared with women and adult clients aged ≥30 years, similar high proportions of men and persons aged 15-29 years enrolled in HIV care and received same-day ART. To help achieve 90-90-90 by 2020, the United States President's Emergency Plan for AIDS Relief (PEPFAR) is supporting the national scale-up of CommLink in Eswatini and

HIV infection risk factors among male-to-female transgender persons: a review of the literature.

PubMed

De Santis, Joseph P

2009-01-01

Male-to-female (MTF) transgender women experience a host of psychosocial issues such as discrimination, stigmatization, and marginalization. These challenges often limit economic opportunities, affect mental health, and may place members of this population at an increased risk for HIV infection. This report presents a review of the literature that focuses on risk factors for HIV infection specific to the MTF population. Factors including needle sharing and substance abuse, high-risk sexual behaviors, commercial sex work, health care access, lack of knowledge regarding HIV transmission, violence, stigma and discrimination, and mental health issues have been identified in the literature as risk factors for the acquisition of HIV infection by members of this population. Implications for care provided to MTF transgender persons are presented, and suggestions for future research are identified.

In the United States (US), foreign-born persons are disproportionately affected by HIV and differ epidemiologically from US-born persons with diagnosed HIV infection. Understanding HIV transmission dynamics among foreign-born persons is important to guide HIV prevention efforts for these populations. We conducted molecular transmission network analysis to describe HIV transmission dynamics among foreign-born persons with diagnosed HIV. Using HIV-1 polymerase nucleotide sequences reported to the US National HIV Surveillance System for persons with diagnosed HIV infection during 2001-2013, we constructed a genetic distance-based transmission network using HIV-TRACE and examined the birth region of potential transmission partners in this network. Of 77,686 people, 12,064 (16%) were foreign born. Overall, 28% of foreign-born persons linked to at least one other person in the transmission network. Of potential transmission partners, 62% were born in the United States, 31% were born in the same region as the foreign-born person, and 7% were born in another region of the world. Most transmission partners of male foreign-born persons (63%) were born in the United States, whereas most transmission partners of female foreign-borns (57%) were born in their same world region. These finding suggests that a majority of HIV infections among foreign-born persons in our network occurred after immigrating to the United States. Efforts to prevent HIV infection among foreign-born persons in the United States should include information of the transmission networks in which these individuals acquire or transmit HIV to develop more targeted HIV prevention interventions.

One goal of the HIV care continuum is achieving viral suppression (VS), yet disparities in suppression exist among subpopulations of HIV-infected persons. We sought to identify disparities in both the ability to achieve and sustain VS among an urban cohort of HIV-infected persons in care. Data from HIV-infected persons enrolled at the 13 DC Cohort study clinical sites between January 2011 and June 2014 were analyzed. Univariate and multivariate logistic regression were conducted to identify factors associated with achieving VS (viral load < 200 copies/ml) at least once, and Kaplan-Meier (KM) curves and Cox proportional hazards models were used to identify factors associated with sustaining VS and time to virologic failure (VL ≥ 200 copies/ml after achievement of VS). Among the 4311 participants, 95.4% were either virally suppressed at study enrollment or able to achieve VS during the follow-up period. In multivariate analyses, achieving VS was significantly associated with age (aOR: 1.04; 95%CI: 1.03-1.06 per five-year increase) and having a higher CD4 (aOR: 1.05, 95% CI 1.04-1.06 per 100 cells/mm(3)). Patients infected through perinatal transmission were less likely to achieve VS compared to MSM patients (aOR: 0.63, 95% CI 0.51-0.79). Once achieved, most participants (74.4%) sustained VS during follow-up. Blacks and perinatally infected persons were less likely to have sustained VS in KM survival analysis (log rank chi-square p ≤ .001 for both) compared to other races and risk groups. Earlier time to failure was observed among females, Blacks, publically insured, perinatally infected, those with longer standing HIV infection, and those with diagnoses of mental health issues or depression. Among this HIV-infected cohort, most people achieved and maintained VS; however, disparities exist with regard to patient age, race, HIV transmission risk, and co-morbid conditions. Identifying populations with disparate outcomes allows for appropriate targeting

Diarrhea is an important health problem among HIV-infected patients. This study evaluates the role of HIV on the epidemiology, etiology and severity of diarrheal disease among children. The Global Enteric Multicenter Study enrolled children with moderate-to-severe (MSD) and less severe (LSD) diarrhea between December 2007 and November 2012. One to three controls for MSD cases and one per LSD case were enrolled and matched by age, sex and neighborhood. All children were tested for HIV. Clinical, anthropometric data and stools were collected. A follow-up was performed at 60 days. 214 MSD cases and 418 controls, together with 349 LSD cases and 214 controls were tested. HIV prevalence among MSD cases was 25% (4% for matched controls) and 6% among LSD cases (6% among matched controls). HIV-infected children were more likely to have MSD (OR=5.6, p< 0.0001). Mortality rates were higher among HIV-infected children compared with uninfected (34 vs. 5 per 1000 children-weeks at risk; p=0.0039). Cryptosporidium, Giardia, EAEC (aatA only) were more prevalent among HIV-infected MSD-cases than uninfected ones. HIV is an important risk factor for MSD. The high mortality rate implies that children with MSD should be screened for HIV and managed accordingly. Copyright © 2018. Published by Elsevier Ltd.

The objective of this study was to examine the incidence of fractures in HIV-infected children and comparable HIV-exposed, uninfected (HEU) children in a multicenter, prospective cohort study (PACTG 219/219C) in the United States. The main outcome was first fracture during the risk period. Nine fractures occurred in 7 of 1326 HIV-infected and 2 of 649 HEU children, corresponding to incidence rates of 1.2 per 1000 person-years and 1.1 per 1000 person-years, respectively. The incidence rate ratio was 1.1 (95% CI 0.2, 5.5). There was no evidence of a substantially increased risk of fracture in HIV-infected compared to HEU children.

Travel medicine and HIV infection.

PubMed

Igreja, Ricardo

2008-09-01

The number of HIV-infected persons who travel is increasing. This increase arises from those who have benefited from advances in antiretroviral therapy. The key to successful travel is careful pre-trip planning although many patients do not obtain advice before travelling. Travel advice for HIV patients is becoming increasingly specialized, and includes travel vaccination and highly active antiretroviral therapy-related issues. A closer collaboration between HIV and travel health clinics could provide better care for HIV-infected individuals.

Neuromuscular disorders are common in HIV, occurring at all stages of disease and affecting all parts of the peripheral nervous system. These disorders have diverse etiologies including HIV itself, immune suppression and dysregulation, co-morbid illnesses and infections, and side effects of medications. In this article, we review the following HIV-associated conditions: distal symmetric polyneuropathy, inflammatory demyelinating polyneuropathy, mononeuropathy, mononeuropathy multiplex, autonomic neuropathy, progressive polyradiculopathy due to cytomegalovirus, herpes zoster, myopathy and other rarer disorders.

Background. There are few recent data on the rates of AIDS-defining opportunistic infections (OIs) among human immunodeficiency virus (HIV)–infected patients in care in the United States and Canada. Methods. We studied HIV-infected participants in 16 cohorts in the North American AIDS Cohort Collaboration on Research and Design (NA-ACCORD) during 2000–2010. After excluding 16 737 (21%) with any AIDS-defining clinical events documented before NA-ACCORD enrollment, we analyzed incident OIs among the remaining 63 541 persons, most of whom received antiretroviral therapy during the observation. We calculated incidence rates per 100 person-years of observation (hereafter, “person-years”) with 95% confidence intervals (CIs) for the first occurrence of any OI and select individual OIs during 2000–2003, 2004–2007, and 2008–2010. Results. A total of 63 541 persons contributed 261 573 person-years, of whom 5836 (9%) developed at least 1 OI. The incidence rate of any first OI decreased over the 3 observation periods, with 3.0 cases, 2.4 cases, and 1.5 cases per 100 person-years of observation during 2000–2003, 2004–2007, and 2008–2010, respectively (Ptrend<.001); the rates of most individual OIs decreased as well. During 2008–2010, the leading OIs included Pneumocystis jiroveci pneumonia, esophageal candidiasis, and disseminated Mycobacterium avium complex or Mycobacterium kansasii infection. Conclusions. For HIV-infected persons in care during 2000–2010, rates of first OI were relatively low and generally declined over this time. PMID:27559122

Transgender persons are at high risk for HIV infection, but prevention efforts specifically targeting these people have been minimal. Part of the challenge of HIV prevention for transgender populations is that numerous individual, interpersonal, social, and structural factors contribute to their risk. By combining HIV prevention services with complementary medical, legal, and psychosocial services, transgender persons’ HIV risk behaviors, risk determinants, and overall health can be affected simultaneously. For maximum health impact, comprehensive HIV prevention for transgender persons warrants efforts targeted to various impact levels—socioeconomic factors, decision-making contexts, long-lasting protections, clinical interventions, and counseling and education. We present current HIV prevention efforts that reach transgender persons and present others for future consideration. PMID:27997228

Episodic memory deficits are common in HIV infection and bipolar disorder, but patient insight into such deficits remains unclear. Thirty-four HIV-infected individuals without bipolar disorder (HIV+/BD-) and 47 HIV+ individuals with comorbid bipolar disorder (HIV+/BD+) were administered the Hopkins Verbal Learning Test-Revised and the Brief Visuospatial Memory Test-Revised to examine objective learning/memory functioning. Subjective memory complaints were assessed via the memory subscale of the Patient's Assessment of Own Functioning Inventory. HIV+/BD+ individuals performed poorer on tests of visual learning and visual/verbal recall than did HIV+/BD- participants (ps < .05). Memory complaints only predicted verbal learning (at a trend level, p = .10) and recall (p = .03) among the HIV+/BD- individuals. Memory complaints were not associated with memory performance within the HIV+/BD+ group (ps > .10). Memory complaints were associated with depressive symptoms in both groups (ps < 0.05). These complaints were also predictive of immunosuppression, higher unemployment, and greater dependence on activities of daily living among the HIV+/BD+ individuals (ps < .05). Awareness of memory abilities was particularly poor among HIV+/BD+ individuals (i.e., objective learning/memory did not correspond to reported complaints), which has important implications for the capacity of these individuals to engage in error-monitoring and compensatory strategies in daily life. Memory complaints are associated with depressed mood regardless of group membership. Among HIV+/BD+ individuals, these complaints may also signify worse HIV disease status and problems with everyday functioning. Clinicians and researchers should be cognizant of what these complaints indicate in order to lead treatment most effectively; use of objective neurocognitive assessments may still be warranted when working with these populations.

Understanding frailty, aging, and inflammation in HIV infection.

Frailty is a clinical syndrome initially characterized in geriatric populations with a hallmark of age-related declines in physiologic reserve and function and increased vulnerability to adverse health outcomes. Recently, frailty has increasingly been recognized as a common and important HIV-associated non-AIDS (HANA) condition. This article provides an overview of our current understanding of frailty and its phenotypic characteristics and evidence that they are related to aging and to chronic inflammation that is associated with aging and also with long-term treated HIV infection. The etiology of this chronic inflammation is unknown but we discuss evidence linking it to persistent infection with cytomegalovirus in both geriatric populations and people living with HIV infection.

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

Background. Neurocognitive impairment (NCI) remains an important complication in persons infected with human immunodeficiency virus (HIV). Ancestry-related mitochondrial DNA (mtDNA) haplogroups have been associated with outcomes of HIV infection and combination antiretroviral therapy (CART), and with neurodegenerative diseases. We hypothesize that mtDNA haplogroups are associated with NCI in HIV-infected adults and performed a genetic association study in the CNS HIV Antiretroviral Therapy Effects Research (CHARTER) cohort. Methods. CHARTER is an observational study of ambulatory HIV-infected adults. Haplogroups were assigned using mtDNA sequence, and principal components were derived from ancestry-informative nuclear DNA variants. Outcomes were cross-sectional global deficit score (GDS) as a continuous measure, GDS impairment (GDS ≥ 0.50), and HIV-associated neurocognitive disorder (HAND) using international criteria. Multivariable models were adjusted for comorbidity status (incidental vs contributing), current CART, plasma HIV RNA, reading ability, and CD4 cell nadir. Results. Haplogroups were available from 1027 persons; median age 43 years, median CD4 nadir 178 cells/mm3, 72% on CART, and 46% with HAND. The 102 (9.9%) persons of genetically determined admixed Hispanic ancestry had more impairment by GDS or HAND than persons of European or African ancestry (P < .001 for all). In multivariate models including persons of admixed Hispanic ancestry, those with haplogroup B had lower GDS (β = −0.34; P = .008) and less GDS impairment (odds ratio = 0.16; 95% confidence interval, .04, .63; P = .009) than other haplogroups. There were no significant haplogroup associations among persons of European or African ancestry. Conclusions. In these mostly CART-treated persons, mtDNA haplogroup B was associated with less NCI among persons of genetically determined Hispanic ancestry. mtDNA variation may represent an ancestry-specific factor influencing NCI in HIV-infected

Guidelines recommend risk-reduction counseling by HIV providers to all HIV-infected persons. Among HIV-infected adults receiving medical care in the United States, we estimated prevalence of exposure to three types of HIV/sexually transmitted disease (STD) risk-reduction interventions and described the characteristics of persons who received these interventions. Data were from the Medical Monitoring Project (MMP), a supplemental HIV surveillance system designed to produce nationally representative estimates of behavioral and clinical characteristics of HIV-infected adults receiving medical care in the United States. Descriptive analyses were conducted to estimate the exposure to each type of HIV/STD risk-reduction intervention. Bivariate and multivariable analyses were conducted to assess associations between the selected correlates with each exposure variable. About 44% of participants reported a one-on-one conversation with a healthcare provider about HIV/STD prevention, 30% with a prevention program worker, 16% reported participation in a small group risk-reduction intervention, and 52% reported receiving at least one of the three interventions in the past 12 months. Minority race/ethnicity, low income, and risky sexual behavior consistently predicted greater intervention exposure. However, 39% of persons who reported risky sex did not receive any HIV/STD risk-reduction interventions. HIV-infected persons in care with fewer resources or those who engaged in risk behaviors were more likely to receive HIV/STD risk-reduction interventions. However, less than half of HIV-infected persons in care received HIV/STD prevention counseling from their provider, an intervention that has been shown to be effective and is supported by guidelines.

Antiretroviral tritherapy has contributed to a considerable reduction in HIV-related mortality. The causes of death are dominated by opportunistic infections in developing countries and by cardiovascular diseases and cancer in developed countries. To determine the causes and risk factors associated with death in HIV-infected patients in two Tunisian medical centers. cross-sectional study of HIV-infected patients over 15 years treated at Sousse and Monastir medical centers between 2000 and 2014. Death was considered related to HIV if its primary cause was AIDS-defining illness or if it was due to an opportunistic infection of unknown etiology with CD4 < 50 cells/mm 3 ; it was considered unrelated to HIV if its primary cause wasn't an AIDS defining illness or if it was due to an unknown cause if no information was available. Two hundred thirteen patients, 130 men (61%) and 83 women (39%), average age 40 ± 11 years were enrolled in the study. Fifty four patients died, the mortality rate was 5.4/100 patients/year. Annual mortality rate decreased from 5.8% in 2000-2003 to 2.3% in 2012-2014. Survival was 72% at 5 years and 67% at 10 years. Death events were associated with HIV in 70.4% of cases. The leading causes of death were pneumocystis carinii pneumonia and cryptococcal meningitis in 6 cases (11%) each. Mortality risk factors were a personal history of opportunistic infections, duration of antiretroviral therapy < 12 months and smoking. Strengthening screening, early initiation of antiretroviral therapy and fight against tobacco are needed to reduce mortality in patients infected with HIV in Tunisia.

Objectives Streptococcus pneumoniae is the leading cause of bacterial pneumonia and associated bacteremia during HIV infection. Rapid diagnostic assays may limit inappropriate therapy. Methods Clinical signs and symptoms and sera and urine were collected prospectively from 70 adults with pneumococcal pneumonia, including 47 with HIV co-infection. Pneumococcal C-polysaccharide antigen was detected in urine using the Binax® immunochromatographic test (ICT). A systematic review of 24 published studies was conducted. Results Clinical symptoms, signs, and laboratory parameters except leukocytosis, were similar in HIV-infected and HIV-seronegative pneumonia. The performance of the urine antigen ICT was independent of HIV-status (sensitivity 81%, specificity 98%, positive (PPV) and negative predictive values (NPV) 98%, and 82%, respectively). The sensitivity of sputum Gram’s stain was 58% [34/59] with sputum unable to be provided by 16%. The CRP response was identical in HIV-infected (mean ± SD) 133 ± 88 vs. seronegative 135 ± 104 mg/L (p=0.9). In the systematic review, the ICT performance revealed 74% sensitivity (95% CI: 72% to 77%) and 94% specificity (95% CI: 93% to 95%). Urine antigen testing increases etiologic diagnosis by 23% (Range: 10% –59%) when testing adults with community acquired pneumonia of unknown etiology. Conclusions Urinary antigen detection provides a credible rapid diagnostic test for pneumococcal pneumonia regardless of HIV-status. CRP response to acute infection is similar in HIV co-infection and increases diagnostic certainty. PMID:17692384

Sexually transmitted infections (STI)/HIV rates are disproportionately high among men involved in the criminal justice system. Mental health disorders, including personality disorders, are also elevated among inmates. Borderline personality disorder (BPD) may be an important risk factor for STI/HIV, yet remains relatively understudied, particularly among inmates. We used baseline data from Project DISRUPT, a cohort study of African American men being released from prison in North Carolina who were in heterosexual relationships at prison entry (n=189), to assess their STI/HIV risk in the 6 months before incarceration and BPD symptoms focused on emotional lability and relationship dysfunction. We created a continuous BPD symptom severity score and a dichotomous BPD indicator split at the top quartile of the score (BPD-TQ) to examine associations between BPD and STI/HIV outcomes using logistic regression. We also examined associations between individual symptoms and outcomes. After adjustment for sociodemographics and antisocial personality disorder, BPD-TQ was associated with sexual risk behaviors including multiple partnerships (adjusted odds ratio, 2.58; 95% confidence interval, 1.24-5.36) and sex with nonmonogamous partners (adjusted odds ratio, 2.54; 95% confidence interval, 1.17-5.51). Prevalence of previous STI (47.5% vs. 29.6%) and prevalent chlamydial infection (6.9% vs. 3.1%) seemed higher in those in BPD-TQ, although the associations were not statistically significant. Associations were similar to those with the continuous score. Borderline personality disorder symptoms most associated with STI/HIV risk were abandonment worry, mood swings, and shifts in opinions. Borderline personality disorder is strongly associated with STI/HIV risk in this sample. Researchers should further evaluate the relationship between STI/HIV and BPD, in addition to mood disorders.

HIV infection is commonly associated with emotional and cognitive disorders that recognize both causes of an organic nature (related to the virus itself) and non-organic factors (emotional stress resulting from HIV diagnosis, social stigma and continued risk behaviour such as alcohol or drug abuse). Most of the literature has focused attention on depressive disorder, the most common mental disorder in the HIV population. In our analysis we evaluated the presence of personality disorders and alexithymia in a group of patients seropositive for HIV through appropriate psychological tests. Our data revealed a close relationship between socio-emotional alienation, distorted body perception and the difficulty in relating with each other, which is perceived as threatening and judgmental; this concept takes us back to the social stigma that modifies the emotional communication of HIV patients. The illness is experienced as an outsider that modifies the body, imprisons the emotionalism and cannot be controlled. Such personality alterations stop the emotional communication, thereby developing alexithymia.

Human Papilloma Virus-Associated Lips Verrucous Carcinoma in HIV-Infected Male.

Human papillomavirus (HPV) infection, widely known as the necessary cause of cervical cancer, has been established as a major etiologic factor for head and neck cancer (HNC). HIV-infected individuals are at higher risk of HPV-associated cancers than the general population. We describe a 45-year-old man with HIV and HPV coinfection, who presented progressively enlarging verrucous neoformations of the lips. The final diagnosis of verrucous carcinoma was delayed. Early detection of HPV lesions in oral mucosa and HPV screening activities could be important in improving the diagnostic sensitivity for the HIV-infected patients with oral cancer.

Although several studies have characterized patterns and predictors of continued risky sexual behavior in HIV-infected rural persons, far less research has evaluated interventions to reduce risky sex in this group. This pilot randomized clinical trial compared 2 brief telephone-administered interventions designed to reduce continued risky sexual behaviors in HIV-infected rural persons. Participants were 79 HIV-infected rural persons who reported 1 or more occasions of unprotected anal, vaginal, or oral sex in the past 2 months. Participants were recruited through AIDS service organizations in rural areas of 27 states and assigned randomly to either a 2-session, motivational interviewing plus skills-building intervention (i.e., integrated intervention; n = 48) or a 2-session, skills-building only comparison intervention (n = 31). Participants completed self-report measures of sexual behaviors and factors related to risky sex at preintervention and 2-month follow-up. Before enrolling into the intervention, 37% of participants had 2 or more sexual partners in the past 2 months, 29% had sex with 1 or more partners without knowing their partners' HIV serostatus, and almost one-third of participants located sex partners in high-risk environments (e.g., public parks, roadside rest areas). A 2 x 2 repeated measures multivariate analyses of variance found that integrated intervention participants reported greater increases in risk-reduction motivation and greater increases in condom-protected vaginal and oral intercourse occasions at follow-up compared to skills-building only participants. Brief telephone-administered interventions that integrate motivational interviewing with skills-building show potential to reduce risky sexual behaviors in HIV-infected rural persons. Additional and large-scale evaluations of this intervention approach appear warranted.

The incidence of recent hepatitis C virus infection (HCV) infection has been noted to be increasing among men who have sex with men (MSM), especially those with HIV infection, in several resource-rich settings. In Taiwan, the incidence of recent HCV infection increased from 0 in 1994-2000, 2.29 in 2001-2005 to 10.13 per 1000 person-years of follow-up (PYFU) in 2006-2010. In this study, we aimed to estimate the incidence rate of recent HCV infection among those individuals who sought voluntary counselling and testing (VCT) service at a University Hospital. Between May 2006 and December 2013, 18,246 tests for HIV antibody were performed among 12,143 individuals at the VCT services. A total of 2157 clients without HIV or HCV infection at baseline were included for estimation of incidence rate of recent HCV infection. Antibodies to HCV were determined with a third-generation enzyme immunoassay. A nested case-control study with four matched controls without HCV seroconversion for one HCV seroconverter was conducted to investigate the factors associated with recent HCV infection. Phylogenetic analysis was performed among the HCV strains obtained from VCT clients and patients coinfected with HIV and HCV between 2006 and 2013. During the study period, 2157 clients received a total of 8260 tests. The HCV seroprevalence at baseline was 0.3%. Of the 2150 HCV-negative clients who contributed 5074.99 PYFU, 17 developed HCV seroconversion (incidence rate, 3.35 per 1000 PYFU; 95% CI, 1.76-4.94); the rate increased from 2.28 per 1000 PYFU (95% CI, 0.05-4.51) in 2006-2009, to 3.33 per 1000 PYFU (95% CI, 0.86-5.80) in 2010-2011, to 4.94 per 1000 PYFU (95% CI, 0.99-8.99) in 2012-2013. In case-control study, HCV seroconverters were more likely to have HIV-infected partners, recent syphilis and a Rapid Plasma Reagin (RPR) titre of 4 or greater. In multivariate analysis, having HIV-infected partners remained as the only independent associated factors with HCV seroconversion (AOR, 6

Solid Organ Transplants in HIV-infected Patients

There is a growing need for kidney and liver transplants in persons living with HIV. Fortunately, with the significant advances in antiretroviral therapy and management of opportunistic infections, HIV infection is no longer an absolute contraindication for solid organ transplantation. Data from several large prospective multi-center cohort studies have shown that solid organ transplantation in carefully selected HIV-infected individuals is safe. However, significant challenges have been identified including prevention of acute rejection, management of drug-drug interactions and treatment of recurrent viral hepatitis. This article reviews the selection criteria, outcomes, and special management considerations for HIV-infected patients undergoing liver or kidney transplantation. PMID:23893004

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

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. 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 1454 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 ARVs self-reported a mean CD4 count of 418. 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. This study documents that this sample of 1454 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.

As of December 31, 2009, an estimated 864,748 persons were living with human immunodeficiency virus (HIV) infection in the 50 U.S. states, the District of Columbia, and six U.S.-dependent areas. Whereas HIV surveillance programs in the United States collect information about persons with a diagnosis of HIV infection, supplemental surveillance systems collect in-depth information about the behavioral and clinical characteristics of persons receiving outpatient medical care for HIV infection. These data are needed to reduce HIV-related morbidity and mortality and HIV transmission. Data were collected during June 2009-May 2010 for patients receiving medical care at least once during January-April 2009. The Medical Monitoring Project (MMP) is an ongoing surveillance system that assesses behaviors and clinical characteristics of HIV-infected persons who have received outpatient medical care. For the 2009 data collection cycle, participants must have been aged ≥18 years and have received medical care during January-April 2009 at sampled facilities that provide HIV medical care within participating MMP project areas. Behavioral and selected clinical data were collected using an in-person interview, and most clinical data were collected using medical record abstraction. A total of 23 project areas in 16 states and Puerto Rico were funded to collect data during the 2009 data collection cycle. The data were weighted for probability of selection and nonresponse to be representative of adults receiving outpatient medical care for HIV infection in the United States and Puerto Rico. Prevalence estimates are presented as weighted percentages. The period of reference is the 12 months before the patient interview unless otherwise noted. The patients in MMP represent 421,186 adults who received outpatient medical care for HIV infection in the United States and Puerto Rico during January-April 2009. Of adults who received medical care for HIV infection, an estimated 71.2% were male

Unusual primary HIV infection with colonic ulcer complicated by hemorrhagic shock: a case report

PubMed Central

2010-01-01

Introduction Timely diagnosis of primary HIV infection is important to prevent further transmission of HIV. Primary HIV infection may take place without symptoms or may be associated with fever, pharyngitis or headache. Sometimes, the clinical presentation includes aseptic meningitis or cutaneous lesions. Intestinal ulceration due to opportunistic pathogens (cytomegalovirus, Epstein-Barr virus, Toxoplasma gondii) has been described in patients with AIDS. However, although invasion of intestinal lymphoid tissue is a prominent feature of human and simian lentivirus infections, colonic ulceration has not been reported in acute HIV infection. Case description A 42-year-old Caucasian man was treated with amoxicillin-clavulanate for pharyngitis. He did not improve, and a rash developed. History taking revealed a negative HIV antibody test five months previously and unprotected sex with a male partner the month before admission. Repeated tests revealed primary HIV infection with an exceptionally high HIV-1 RNA plasma concentration (3.6 × 107 copies/mL) and a low CD4 count (101 cells/mm3, seven percent of total lymphocytes). While being investigated, the patient had a life-threatening hematochezia. After angiographic occlusion of a branch of the ileocaecal artery and initiation of antiretroviral therapy, the patient became rapidly asymptomatic and could be discharged. Colonoscopy revealed a bleeding colonic ulcer. We were unable to identify an etiology other than HIV for this ulcer. Conclusion This case adds to the known protean manifestation of primary HIV infection. The lack of an alternative etiology, despite extensive investigations, suggests that this ulcer was directly caused by primary HIV infection. This conclusion is supported by the well-described extensive loss of intestinal mucosal CD4+ T cells associated with primary HIV infection, the extremely high HIV viral load observed in our patient, and the rapid improvement of the ulcer after initiation of highly

Outbreaks of syphilis have been described among HIV-infected men who have sex with men (MSM) in Western communities, whereas reports in Asian countries are limited. We aimed to characterize the incidence and temporal trends of syphilis among HIV-infected MSM compared with HIV-infected non-MSM in Asian countries. Patients enrolled in the TREAT Asia HIV Observational Database cohort and with a negative non-treponemal test since enrolment were analyzed. Incidence of syphilis seroconversion, defined as a positive non-treponemal test after previously testing negative, was evaluated among patients at sites performing non-treponemal tests at least annually. Factors associated with syphilis seroconversion were investigated at sites doing non-treponemal testing in all new patients and subsequently testing routinely or when patients were suspected of having syphilis. We included 1010 patients from five sites that performed non-treponemal tests in all new patients; those included had negative non-treponemal test results during enrolment and subsequent follow-ups. Among them, 657 patients were from three sites conducting regular non-treponemal testing. The incidence of syphilis seroconversion was 5.38/100 person-years (PY). Incidence was higher in MSM than non-MSM (7.64/100 PY vs. 2.44/100 PY, p< 0.001). Among MSM, the incidence rate ratio (IRR) for every additional year from 2009 was 1.19 ( p= 0.051). MSM status (IRR 3.48, 95% confidence interval (CI) 1.88-6.47), past syphilis diagnosis (IRR 5.15, 95% CI 3.69-7.17) and younger age (IRR 0.84 for every additional 10 years, 95% CI 0.706-0.997) were significantly associated with syphilis seroconversion. We observed a higher incidence of syphilis seroconversion among HIV-infected MSM and a trend to increasing annual incidence. Regular screening for syphilis and targeted interventions to limit transmission are needed in this population.

B vitamins may have beneficial roles in reducing inflammation; however, research on the role of B vitamins in inflammation among HIV-infected persons is lacking. This study assessed the association between B vitamins and serum C-reactive protein (CRP) concentrations in HIV-infected persons. A cross-sectional survey was conducted among 314 HIV-infected persons (180 men and 134 women) aged 18 to 60 years residing in the Kathmandu, Nepal. High-sensitive and regular serum CRP concentrations were measured by the latex agglutination nephelometry and latex agglutination turbidimetric method, respectively. Dietary intake was assessed using 2 nonconsecutive 24-hour dietary recalls. The relationships between B vitamins and serum CRP concentrations were assessed using multiple regression analysis. The multivariate-adjusted geometric mean of serum CRP concentrations was significantly decreased with an increasing B vitamins intake across quartiles of niacin (P for trend = .007), pyridoxine (P for trend = .042), and cobalamin (P for trend = .037) in men. In men, the mean serum CRP concentrations in the highest quartiles of niacin, pyridoxine, and cobalamin were 63%, 38%, and 58%, respectively, lower than that in the lowest quartile. In women, the mean serum CRP concentrations in the highest quartiles of riboflavin (P for trend = .084) and pyridoxine (P for trend = .093) were 37% and 47%, respectively, lower than that in the lowest quartile. High intake of niacin, pyridoxine, or cobalamin was independently associated with decreased serum CRP concentrations among HIV-infected men. Further prospective studies are warranted to confirm the role of B vitamins in inflammation among HIV-infected persons. © The Author(s) 2016.

Assessing immune aging in HIV-infected patients

PubMed Central

Appay, Victor; Sauce, Delphine

2017-01-01

ABSTRACT Many of the alterations that affect innate and adaptive immune cell compartments in HIV-infected patients are reminiscent of the process of immune aging, characteristic of old age. These alterations define the immunological age of individuals and are likely to participate to the decline of immune competence with HIV disease progression. It is therefore important to characterize these changes, which point toward the accumulation of highly differentiated immunocompetent cells, associated with overall telomere length shortening, as well as understanding their etiology, especially related to the impact of chronic immune activation. Particular attention should be given to the exhaustion of primary immune resources, including haematopoietic progenitors and naïve cells, which holds the key for effective hematopoiesis and immune response induction, respectively. The alteration of these compartments during HIV infection certainly represents the foundation of the immune parallel with aging. PMID:27310730

A large number of AIDS/sexually transmitted disease (STD) helplines provide support to people seeking information how to avoid infection with HIV or how to deal with the infection if they have already contracted it. Nevertheless, limited knowledge is available about how such helplines are being utilized by different segments of the population and what the main concerns of the people calling the helplines are. The goal of this study was to evaluate the use of the State AIDS/STD Hotline in New Jersey and describe the information needs of its callers. Callers were categorized as either having HIV or being free of the virus based on their self-reported HIV status. A cross-sectional design was then used combining caller information from the New Jersey AIDS/STD Hotline with data from the state health department on the number of people living with HIV in each county in New Jersey. The utilization rate of the New Jersey AIDS/STD Hotline was significantly higher among persons with HIV infection compared to the utilization rate among persons who were either free of the virus or unaware of their HIV status. The callers infected with HIV differed significantly from the rest of the callers in terms of the type of information they requested. While callers who had the infection were most likely to ask about treatment options, financial assistance, and support groups, the rest of the callers were more likely to inquire about testing site location and prevention information.

Introduction: In addition to adequate diagnosis and treatment of HIV-infected individuals, development, scientific substantiation and implementation of psycho-hygienic measures aimed at correcting the processes of forming personality traits and improving the psycho-emotional state of HIV-infected individuals are of particular importance. The aim: The purpose of the scientific research was to determine the most significant changes of situational and personal anxiety indicators, the degree of gravity of the asthenic state and depressive manifestations that were recorded in the context of the introduction of a number of measures for psycho-hygienic correction. Materials and methods: To determine the peculiarities of the impact of the proposed measures of psycho-hygienic correction and the study of the consequences of their implementation, two groups of comparison were created: a control group and an intervention group. 30 HIV-infected men who used a complex of measures for psycho-hygienic correction of personality traits and improvement of psycho-emotional state in their daily activities were included in the intervention group; 30 HIV-infected men who did not use this complex in their daily activities were included in the control group. Diagnosis and assessment of the anxiety of HIV-infected persons were carried out on the basis of The State-Trait Anxiety Inventory (STAI). The absence or presence of manifestations of an asthenic personality disorder in the subjects was determined by means of a test method created by L. Malkova for assessing asthenia. In order to determine the degree of manifestation of this characteristic, the psychic state of a person, as a level of expression of a depressive state, the psychometric Zung Depression Rating Scale was used to assess depression. Results: Studies have found that there was a statistically valid decrease of the level of indicators of situational anxiety among the representatives of the intervention group which reduced from

The HIV surveillance system in Germany is based on mandatory, anonymous notification of newly diagnosed HIV cases by laboratories. Because the time between HIV infection and the diagnosis of HIV varies widely between persons, it is difficult to determine the number of cases of recent HIV infection among newly diagnosed cases of HIV. In Germany, the BED-capture-enzyme immunoassay (BED-CEIA) has been used to distinguish between recent and long-standing HIV infection. The aim of this analysis is to report the proportion of cases of recent HIV infection among newly diagnosed cases in Germany between 2008 and 2014 and to identify factors associated with recent infections. A sample of voluntary laboratories among all HIV diagnostic laboratories was recruited. Residual blood from HIV diagnostic tests was spotted on filter paper as dried serum or dried plasma spots and was sent along with the notification form of the HIV cases. The BED-CEIA test was performed. A case was defined as recent HIV infection with a BED-CEIA test result of less than 0.8 normalized optical density, with the exclusion of CDC stage C. The proportion of recent newly diagnosed HIV infections among different groups (such as transmission groups, gender or age groups) was calculated. We used logistic regression to identify factors associated with recent HIV infection and to identify subpopulations with high proportions of recent HIV infections. Approximately 10,257 newly diagnosed cases were tested for recency using the BED-CEIA. In total, 3084 (30.4%) of those were recently infected with HIV. The highest proportion of recent HIV infections was found among men who had sex with men (MSM) (35%) and persons between 18 and 25 years of age (43.0%). Logistic regression revealed that female German intravenous drug users with a recent HIV infection had a higher chance of being detected than German MSM (OR 2.27). Surveillance of recent HIV infection is a useful additional tool to monitor the HIV epidemic in

More than three decades after recognition of acquired immunodeficiency syndrome (AIDS) in the United States, the pandemic of human immunodeficiency virus (HIV) infection has dramatically changed the global burden of disease. The main goal of this research is retrospective analysis of epidemiological and clinical characteristics of 28 HIV infected patients, who were diagnosed and treated at the Clinic for Infectious Diseases in University Clinical Center Tuzla in the period from 1996 until the end of 2013. Retrospective analysis was performed using the medical records of 28 HIV-infected persons. Two rapid tests were used for HIV testing: OraQuick Advance test, Vikia HIV1/2, Elisa combo test, HIV RNA test. AIDS disease was determined by using the criteria from WHO. Among a total of 28 HIV-infected persons, 23 (82.14%) were males and 5 (17.86%) were females, with the male: female ratio of 4,6:1. In terms of the transmission route, a large proportion of cases were infected through heterosexual contact 19 (67.86%). At the time of the first visit, 16 (57.15%) patients showed asymptomatic HIV infection, 4 (14.28%) HIV infection with symptoms other than the AIDS defining diseases, and 8 (28.57) had AIDS. At the time of first hospital visit, the CD4 + cells count ranged from 40 to 1795/µl (conducted in 19 patients), and mean value of CD4 + cells was 365,31/µl, and mean HIV RNA titer was 287 118 copies/ml³. Of 28 HIV-infected persons 39 cases of opportunistic diseases developed in 12 patients (42.9%). In terms of the frequency of opportunistic diseases, tuberculosis (12 cases, 42.9%). Among a total of 28 HIV-infected patients, 6 (21.4%) of them died. This study characterizes the epidemiological and clinical patterns of HIV-infected patients in Tuzla region of Bosnia and Herzegovina to accurately understand HIV infection/AIDS in our region, in the hope to contribute in the establishment of effective HIV guidelines in the Tuzla region of B&H in the future.

Background Control of genital infections remains challenging in most regions. Despite advocacy by the World Health Organization (WHO) for syndromic case management, there are limited data on the syndromic approach, especially in HIV care settings. This study compared the syndromic approach against laboratory diagnosis among women in HIV care in Kenya. Methods A mobile team visited 39 large HIV care programs in Kenya and enrolled participants using population-proportionate sampling. Participants provided behavioral and clinical data with genital and blood specimens for lab testing. Results Among 1,063 women, 68.4% had been on antiretroviral therapy >1 year; 58.9% were using cotrimoxazole prophylaxis; 51 % had CD4+T-lymphocytes < 350 cells/mL. Most women (63.1%) reported at least one genital symptom. Clinical signs were found in 63% of women; and 30.8% had an etiological diagnosis. Bacterial vaginosis (17.4%), vaginal candidiasis (10.6%) and trichomoniasis (10.5%) were the most common diagnoses. Using laboratory diagnoses as gold standard, sensitivity and positive predictive value of the syndromic diagnosis for vaginal discharge were 47.6% and 52.7%, respectively, indicating a substantial amount of overtreatment. A systematic physical examination increased by 9.3% the positive predictive value for genital ulcer disease. Conclusions Women attending HIV care programs in Kenya have high rates of vaginal infections. Syndromic diagnosis was a poor predictor of those infections. PMID:25614522

We examined durable viral suppression, cumulative viral load (VL) burden, and transmission risk potential among human immunodeficiency virus (HIV)-diagnosed persons in care. Using data from the National HIV Surveillance System from 17 jurisdictions with complete reporting of VL test results, we determined the percentage of persons in HIV care who achieved durable viral suppression (all VL results <200 copies/mL) and examined viremia copy-years and time spent above VL levels that increase the risk of HIV transmission during 2012-2013. Of 265 264 persons in HIV care in 2011, 238 641 had at least 2 VLs in 2012-2013. The median number of VLs per individual during the 2-year period was 5. Approximately 62% had durable viral suppression. The remaining 38% had high VL burden (geometric mean of viremia copy-years, 7261) and spent an average of 438 days, 316 days, and 215 days (60%, 43.2%, and 29.5% of the 2-year period) above 200, 1500, and 10 000 copies/mL. Women, blacks/African Americans, Hispanics/Latinos, persons with HIV infection attributed to transmission other than male-to-male sexual contact, younger age groups, and persons with gaps in care had higher viral burden and transmission risk potential. Two-thirds of persons in HIV care had durable viral suppression during a 2-year period. One-third had high VL burden and spent substantial time above VL levels with increased risk of onward transmission. More intervention efforts are needed to improve retention in care and medication adherence so that more persons in HIV care achieve durable viral suppression.

Sterling, Timothy R.

Nine months of daily isoniazid is efficacious in treating latent M. tuberculosis infection, but completion rates are low, limiting treatment effectiveness. In 2011, three important studies were published involving novel regimens for the treatment of latent M. tuberculosis infection. At least 36 months of isoniazid was more effective than 6 months of isoniazid in one study, but not in another—both of which were conducted among tuberculin skin test positive HIV-infected adults living in high tuberculosis incidence settings. Three months of once-weekly isoniazid plus rifapentine or twice-weekly isoniazid plus rifampin (both given under direct observation) resulted in tuberculosis rates similar to those seen with 6 months of isoniazid among HIV-infected persons in high tuberculosis incidence settings. Three months of once-weekly, directly-observed isoniazid plus rifapentine was at least as effective as 9 months of daily isoniazid among predominantly HIV-uninfected persons living in low and medium tuberculosis incidence countries. The 3-month once-weekly isoniazid plus rifapentine regimen demonstrates promise for treatment of latent M. tuberculosis infection in HIV-infected persons. PMID:22581360

HIV-positive persons have increased cardiovascular event rates but data on the prevalence of subclinical atherosclerosis compared with HIV-negative persons are not uniform. We assessed subclinical atherosclerosis utilizing coronary artery calcium (CAC) scoring and coronary computed tomography angiography (CCTA) in 428 HIV-positive participants of the Swiss HIV Cohort Study and 276 HIV-negative controls concurrently referred for clinically indicated CCTA. We assessed the association of HIV infection, cardiovascular risk profile, and HIV-related factors with subclinical atherosclerosis in univariable and multivariable analyses. HIV-positive participants (median duration of HIV infection, 15 years) were younger than HIV-negative participants (median age 52 vs. 56 years; P < 0.01) but had similar median 10-year Framingham risk scores (9.0% vs. 9.7%; P = 0.40). The prevalence of CAC score >0 (53% vs. 56.2%; P = 0.42) and median CAC scores (47 vs. 47; P = 0.80) were similar, as was the prevalence of any, non-calcified/mixed, and high-risk plaque. In multivariable adjusted analysis, HIV-positive participants had a lower prevalence of calcified plaque than HIV-negative participants [36.9% vs. 48.6%, P < 0.01; adjusted odds ratio (aOR) 0.57; 95% confidence interval (CI) 0.40-0.82; P < 0.01], lower coronary segment severity score (aOR 0.72; 95% CI 0.53-0.99; P = 0.04), and lower segment involvement score (aOR 0.71, 95% CI 0.52-0.97; P = 0.03). Advanced immunosuppression was associated with non-calcified/mixed plaque (aOR 1.97; 95% CI 1.09-3.56; P = 0.02). HIV-positive persons in Switzerland had a similar degree of non-calcified/mixed plaque and high-risk plaque, and may have less calcified coronary plaque, and lower coronary atherosclerosis involvement and severity scores than HIV-negative persons with similar Framingham risk scores.

A viral etiology of amyotrophic lateral sclerosis (ALS) has been proposed because of the selective vulnerability of motor neurons to certain viruses. During the last 20 years, at least 19 cases of ALS or ALS-like disease have been reported in HIV-1 (HIV) seropositive individuals. To describe two cases of clinically definite ALS in patients with HIV infection and to review the previously reported cases of HIV-associated ALS syndrome. A multidisciplinary ALS center and Neuro-AIDS clinic at a tertiary care university hospital. We investigated and prospectively monitored two patients who had developed clinically definite ALS by El Escorial criteria several years after acquiring the HIV infection. The previously reported cases of ALS or ALS-like disease in patients with HIV infection were reviewed for comparison and contrast with the characteristics of sporadic ALS. The clinical course of ALS in our two HIV seropositive individuals mirrored that of classical sporadic ALS. A review of previously described 19 patients with ALS syndrome revealed clinically definite ALS in 4 cases and clinically probable or possible ALS in 15. ALS commenced at different stages of the HIV disease; in 7 patients, HIV infection was discovered contemporaneously with diagnosis of ALS. CD4+ T cell count ranged from 2 to 560 cells/mm3. Three (1 definite ALS) of the fatal cases were studied at autopsy and all exhibited pathology outside the motor neuron pool. Unlike our patients, 7 of 8 patients with HIV-associated ALS syndrome receiving HAART demonstrated at least partial recovery of their motor deficit. ALS-like syndrome can occur in association with HIV infection; however, the causal relationship remains uncertain. Patients with ALS syndrome related to HIV infection are generally younger in age and often demonstrate pathology outside the motor neuron system. Patients with HIV-associated ALS syndrome may improve following antiretroviral therapy. An aggressive HAART regimen to reduce viral load

Two international, multicenter Phase 2 clinical trials examining fluoroquinolone-containing regimens in adults with smear-positive pulmonary tuberculosis (TB), conducted from July 2003 to March 2007. Both trials enrolled human immunodeficiency virus (HIV) infected participants who were not receiving antiretroviral therapy (ART) at TB treatment initiation. To assess the impact of HIV infection on TB treatment outcomes in Phase 2 clinical trials. Cross-protocol analysis comparing the safety, tolerability and outcomes of anti-tuberculosis treatment by HIV status. Of 750 participants who received at least one dose of study treatment, 123 (16%) were HIV-infected. Treatment completion rates were similar by HIV status (81% infected vs. 85% non-infected), as were rates of week 8 culture conversion (66% infected vs. 63% non-infected), and treatment failure (5% infected vs. 3% non-infected). Among HIV-infected participants, treatment failure detected using liquid media was more frequent in those treated thrice weekly (14% thrice weekly vs. 2% daily, P = 0.03). HIV-infected participants more frequently experienced an adverse event during the intensive phase treatment than non-HIV-infected participants (30% vs. 15%, P < 0.01). HIV-infected persons not receiving ART had more adverse events during the intensive phase of anti-tuberculosis treatment, but tolerated treatment well. Failure rates were higher among HIV-infected persons treated with thrice-weekly intensive phase therapy.

HIV Diagnoses Among Persons Aged 13-29 Years - United States, 2010-2014.

In 2014, persons aged 13-29 years represented 23% of the U.S. population, yet accounted for 40% of diagnoses of human immunodeficiency virus (HIV) infection during the same year (1). During 2010-2014, the rates of diagnosis of HIV infection decreased among persons aged 15-19 years, were stable among persons aged 20-24 years, and increased among persons aged 25-29 years (1). However, these 5-year age groups encompass multiple developmental stages and potentially mask trends associated with the rapid psychosocial changes during adolescence through young adulthood. To better understand HIV infection among adolescents aged 13-17 years and young adults aged 18-29 years in the United States and identify ideal ages to target primary HIV prevention efforts, CDC analyzed data from the National HIV Surveillance System (NHSS)* using narrow age groups. During 2010-2014, rates of diagnosis of HIV infection per 100,000 population varied substantially among persons aged 13-15 years (0.7), 16-17 years (4.5), 18-19 years (16.5), and 20-21 years (28.6), and were higher, but less variable, among persons aged 22-23 years (34.0), 24-25 years (33.8), 26-27 years (31.3), and 28-29 years (28.7). In light of the remarkable increase in rates between ages 16-17, 18-19, and 20-21 years, and a recent study revealing that infection precedes diagnosis for young persons by an average of 2.7 years (2), these findings demonstrate the importance of targeting primary prevention efforts to persons aged <18 years and continuing through the period of elevated risk in their mid-twenties.

To determine the rate and predictors of community-acquired bacterial pneumonia and its effect on human immunodeficiency virus (HIV) disease progression in HIV-infected women, we performed a multiple-site, prospective study of HIV-infected women in 4 cities in the United States. During the period of 1993-2000, we observed 885 HIV-infected and 425 HIV-uninfected women with a history of injection drug use or high-risk sexual behavior. Participants underwent semiannual interviews, and CD4+ lymphocyte count and viral load were assessed in HIV-infected subjects. Data regarding episodes of bacterial pneumonia were ascertained from medical record reviews. The rate of bacterial pneumonia among 885 HIV-infected women was 8.5 cases per 100 person-years, compared with 0.7 cases per 100 person-years in 425 HIV-uninfected women (P < .001). In analyses limited to follow-up after 1 January 1996, highly active antiretroviral therapy (HAART) and trimethoprim-sulfamethoxazole (TMP-SMX) use were associated with a decreased risk of bacterial pneumonia. Among women who had used TMP-SMX for 12 months, each month of HAART decreased bacterial pneumonia risk by 8% (adjusted hazard ratio [HR(adj)], 0.92; 95% confidence interval [CI], 0.89-0.95). Increments of 50 CD4+ cells/mm3 decreased the risk (HR(adj), 0.88; 95% CI, 0.84-0.93), and smoking doubled the risk (HR(adj), 2.12; 95% CI, 1.26-3.55). Bacterial pneumonia increased mortality risk (HR(adj), 5.02; 95% CI, 2.12-11.87), with adjustment for CD4+ lymphocyte count and duration of HAART and TMP-SMX use. High rates of bacterial pneumonia persist among HIV-infected women. Although HAART and TMP-SMX treatment decreased the risk, bacterial pneumonia was associated with an accelerated progression to death. Interventions that improve HAART utilization and promote smoking cessation among HIV-infected women are warranted.

The immunology of Leishmania/HIV co-infection.

Okwor, Ifeoma; Uzonna, Jude Eze

Leishmaniases are emerging as an important disease in human immunodeficiency virus (HIV)-infected persons living in several sub-tropical and tropical regions around the world, including the Mediterranean. The HIV/AIDS pandemic is spreading at an alarming rate in Africa and the Indian subcontinent, areas with very high prevalence of leishmaniases. The spread of HIV into rural areas and the concomitant spread of leishmaniases to suburban/urban areas have helped maintain the occurrence of Leishmania/HIV co-infection in many parts of the world. The number of cases of Leishmania/HIV co-infection is expected to rise owing to the overlapping geographical distribution of the two infections. In Southwestern Europe, there is also an increasing incidence of Leishmania/HIV co-infection (particularly visceral leishmaniasis) in such countries as France, Italy, Spain and Portugal. Studies suggest that in humans, very complex mechanisms involving dysregulation of host immune responses contribute to Leishmania-mediated immune activation and pathogenesis of HIV. In addition, both HIV-1 and Leishmania infect and multiply within cells of myeloid or lymphoid origin, thereby presenting a perfect recipe for reciprocal modulation of Leishmania and HIV-1-related disease pathogenesis. Importantly, because recovery from leishmaniases is associated with long-term persistence of parasites at the primary infection sites and their draining lymph nodes, there is very real possibility that HIV-mediated immunosuppression (due to CD4(+) T cell depletion) could lead to reactivation of latent infections (reactivation leishmaniasis) in immunocompromised patients. Here, we present an overview of the immunopathogenesis of Leishmania/HIV co-infection and the implications of this interaction on Leishmania and HIV disease outcome.

Introduction Outbreaks of syphilis have been described among HIV-infected men who have sex with men (MSM) in Western communities, whereas reports in Asian countries are limited. We aimed to characterize the incidence and temporal trends of syphilis among HIV-infected MSM compared with HIV-infected non-MSM in Asian countries. Methods Patients enrolled in the TREAT Asia HIV Observational Database cohort and with a negative non-treponemal test since enrolment were analyzed. Incidence of syphilis seroconversion, defined as a positive non-treponemal test after previously testing negative, was evaluated among patients at sites performing non-treponemal tests at least annually. Factors associated with syphilis seroconversion were investigated at sites doing non-treponemal testing in all new patients and subsequently testing routinely or when patients were suspected of having syphilis. Results We included 1010 patients from five sites that performed non-treponemal tests in all new patients; those included had negative non-treponemal test results during enrolment and subsequent follow-ups. Among them, 657 patients were from three sites conducting regular non-treponemal testing. The incidence of syphilis seroconversion was 5.38/100 person-years (PY). Incidence was higher in MSM than non-MSM (7.64/100 PY vs. 2.44/100 PY, p<0.001). Among MSM, the incidence rate ratio (IRR) for every additional year from 2009 was 1.19 (p=0.051). MSM status (IRR 3.48, 95% confidence interval (CI) 1.88–6.47), past syphilis diagnosis (IRR 5.15, 95% CI 3.69–7.17) and younger age (IRR 0.84 for every additional 10 years, 95% CI 0.706–0.997) were significantly associated with syphilis seroconversion. Conclusions We observed a higher incidence of syphilis seroconversion among HIV-infected MSM and a trend to increasing annual incidence. Regular screening for syphilis and targeted interventions to limit transmission are needed in this population. PMID:27774955

Human immunodeficiency virus type 1 (HIV-1) is the etiologic agent of acquired immunodeficiency syndrome (AIDS). The pathogenesis of HIV-1-induced disease is complex and characterized by the interplay of both viral and host factors, which together determine the outcome of infection. An improved understanding of the pathogenic mechanisms of AIDS, combined with recent insights into the dynamics of viral infection may provide powerful new opportunities for therapeutic intervention against this virus.

Abacavir use has been associated with cardiovascular risk, but it is unknown whether this association may be partly explained by patients with kidney disease being preferentially treated with abacavir to avoid tenofovir. Our objective was to compare associations of abacavir and tenofovir with cardiovascular risks in HIV-infected veterans. Cohort study of 10 931 HIV-infected patients initiating antiretroviral therapy in the Veterans Health Administration from 1997 to 2007, using proportional hazards survival regression. Primary predictors were exposure to abacavir or tenofovir within the past 6 months, compared with no exposure to these drugs, respectively. Outcomes were time to first atherosclerotic cardiovascular event, defined as coronary, cerebrovascular, or peripheral arterial disease; and time to incident heart failure. Over 60 588 person-years of observation, there were 501 cardiovascular and 194 heart failure events. Age-standardized event rates among abacavir and tenofovir users were 12.5 versus 8.2 per 1000 person-years for cardiovascular disease, and 3.9 and 3.7 per 1000 person-years for heart failure, respectively. In multivariate-adjusted models, including time-updated measurements of kidney function, recent abacavir use was significantly associated with incident cardiovascular disease [hazard ratio 1.48, 95% confidence interval (CI) 1.08-2.04]; the association was similar but nonsignificant for heart failure (1.45, 0.85-2.47). In contrast, recent tenofovir use was significantly associated with heart failure (1.82, 1.02-3.24), but not with cardiovascular events (0.78, 0.52-1.16). Recent abacavir exposure was independently associated with increased risk for cardiovascular events. We also observed an association between recent tenofovir exposure and heart failure, which needs to be confirmed in future studies.

Current and future assays for identifying recent HIV infections at the population level

Summary The precise diagnosis of recent human immunodeficiency virus (HIV) infection is crucial for estimating HIV incidence, defined as the number of new infections in a population, per person at risk, during a specified time period. Incidence assessment is considered to be a tool for surveillance, public health and research. Differentiating recent from long-term HIV infections is possible thanks to the evaluation of HIV-specific immune response development or viral markers measurement. Several methods that enable the recognition of recent HIV-1 infection with the use of a single blood specimen have been developed, and their value for use in population level studies has been demonstrated. However, they are still inadequate due to a variable window period and false recent rates among HIV clades and across populations. Application of these assays at an individual level is far more questionable because of person-to-person variability in the antibody response and the course of HIV infection, and because of the prospective regulatory approval requirements. In this article we review the principles and the limitations of the currently available major laboratory techniques that allow detection of recent HIV infection. The assays based on the alteration of serological parameters, as well as the newest method based on an increase of HIV genetic diversity with the progress of infection, are described. PMID:21525823

To assess associations between the timing of hepatitis B virus (HBV) immunization relative to human immunodeficiency virus (HIV) diagnosis and vaccine effectiveness, US Military HIV Natural History Study cohort participants without HBV infection at the time of HIV diagnosis were grouped by vaccination status, retrospectively followed from HIV diagnosis for incident HBV infection, and compared using Cox proportional hazards models. A positive vaccine response was defined as hepatitis B surface antibody level ≥ 10 IU/L. Of 1,877 participants enrolled between 1989 and 2008, 441 (23%) were vaccinated prior to HIV diagnosis. Eighty percent of those who received vaccine doses only before HIV diagnosis had a positive vaccine response, compared with 66% of those who received doses both before and after HIV and 41% of those who received doses only after HIV (P < 0.01 for both compared with persons vaccinated before HIV only). Compared with the unvaccinated, persons vaccinated only before HIV had reduced risk of HBV infection after HIV diagnosis (hazard ratio = 0.38, 95% confidence interval: 0.20, 0.75). No reduction in HBV infection risk was observed for other vaccination groups. These data suggest that completion of the vaccine series prior to HIV infection may be the optimal strategy for preventing this significant comorbid infection in HIV-infected persons.

Descriptive literature exists on the effects of HIV-related stigma on the lives of people living with HIV infection but few empirical studies have measured perceived HIV stigma nor explored its potential relationship to quality of life (QoL) over time in people living with HIV infection. A cohort study of a purposive convenient sample of 1457 HIV-positive persons was followed for one year in a longitudinal design that examined the effects of stigma and the life satisfaction dimension of the HIV/AIDS Targeted Quality of Life Instrument (HAT-QOL) over time, as well as the influence of other demographic and assessed social variables. Data were collected three times about six months apart from December 2005 to March 2007. The average age in this sample was 36.8 years (SD=8.78, n=1454) and 72.7% (n=1056) were female. The initial sample of participants was balanced among the five countries: Lesotho, Malawi, South Africa, Swaziland, and Tanzania. An attrition analysis demonstrated few demographic differences between those who remained in the study 12 months later compared with those at baseline. However, those who completed the study and who answered the QoL questions had significantly higher life satisfaction scores at baseline than those who left the study. There was a general increase in the report of life satisfaction QoL in all countries over the one-year period. However, as stigma scores increased over time there was a significant decrease in life satisfaction with differing rates of change by country. Certain factors had a positive influence on life satisfaction QoL: positive HIV media reports, taking antiretrovirals, reduced symptom intensity, and disclosure to a friend. This cohort study is the first to document empirically in a longitudinal sample, that perceived HIV stigma has a significantly negative and constant impact upon life satisfaction QoL for people with HIV infection. In the absence of any intervention to address and reduce stigmatization, individuals

The Literature on rhabdomyolysis in the HIV-positive population is sparse and limited. We aimed to explore the incidence, patient characteristics, etiologies and outcomes of rhabdomyolysis in a cohort of HIV-positive patients identified through the Johns Hopkins HIV clinical registry between June 1992 and April 2014. A retrospective analysis of 362 HIV-positive patients with non-cardiac CK elevation ≥1000 IU/L was performed. Both inpatients and outpatients were included. Incidence rate and potential etiologies for rhabdomyolysis were ascertained. The development of acute kidney injury (AKI, defined as doubling of serum creatinine), need for dialysis, and death in the setting of rhabdomyolysis were determined. Logistic regression was used to evaluate the association of peak CK level with the development of AKI. Three hundred sixty two cases of rhabdomyolysis were identified in a cohort of 7079 patients with a 38,382 person years follow-up time. The incidence rate was nine cases per 1000 person-years (95% CI: 8.5-10.5). Infection was the most common etiology followed by compression injury and drug/alcohol use. One-third of cases had multiple potential etiologies. AKI developed in 46% of cases; 20% of which required dialysis. Thirteen percent died during follow-up. After adjustment, AKI was associated with higher CK (OR 2.05 for each 1-log increase in CK [95% CI: 1.40-2.99]), infection (OR 5.48 [95% CI 2.65-11.31]) and higher HIV viral load (OR 1.22 per 1-log increase [95% CI: 1.03-1.45]). Rhabdomyolysis in the HIV-positive population has many possible causes and is frequently multifactorial. HIV-positive individuals with rhabdomyolysis have a high risk of AKI and mortality.

HIV disease is often perceived as a condition affecting young adults. However, approximately 11% of new infections occur in adults aged 50 years or older. Among persons living with HIV disease, it is estimated that more than half will be aged 50 years or older in the near future. In this review, we highlight issues related to HIV prevention and treatment for HIV-uninfected and HIV-infected older Americans, and outline unique considerations and emerging challenges for public health and patient management in these 2 populations.

Little is known about the incidence of anal human papillomavirus (HPV) infection and related sequelae, as well as factors associated with these outcomes, among adolescents who are HIV infected versus HIV uninfected but at risk. We analyzed the data from a multisite US study, the Reaching for Excellence in Adolescent Care and Health Project. Adolescents aged 12 to 18 years who were behaviorally HIV infected (n = 319) or HIV uninfected but at risk (n = 177) were recruited. Incidence rates for anal HPV, high-risk anal HPV, anogenital warts, and anal dysplasia were calculated using Poisson modeling. Factors associated with these outcomes were examined using Cox proportional hazards modeling. Mean age at entry was 16.8 years; mean (SD) follow-up time for detection of anal HPV was 22.4 (10.8) months. Most participants (76%) were female; 70% were black non-Hispanic. HIV-infected (vs. HIV-uninfected) women had a significantly higher incidence of anal HPV (30 vs. 14 per 100 person-years; P = 0.002), high-risk anal HPV (12 vs. 5.3 per 100 person-years; P = 0.04), and anogenital warts (6.7 vs. 1.6 per 100 person-years; P = 0.002) but not anal dysplasia. Although incidence rates were higher for these outcomes among HIV-infected versus HIV-uninfected men, the differences were not statistically significant. Among women, factors associated with anal HPV and related sequelae differed by HIV status and included biological, behavioral, and HIV-related factors. No factors were associated with outcomes in men. HIV-infected versus HIV-uninfected adolescent women had higher rates of anal HPV and anogenital warts. Because HIV-infected youth are at increased risk of these outcomes, enhanced HPV prevention efforts such as vaccination are warranted for this group.

To assess associations between the timing of hepatitis B virus (HBV) immunization relative to human immunodeficiency virus (HIV) diagnosis and vaccine effectiveness, US Military HIV Natural History Study cohort participants without HBV infection at the time of HIV diagnosis were grouped by vaccination status, retrospectively followed from HIV diagnosis for incident HBV infection, and compared using Cox proportional hazards models. A positive vaccine response was defined as hepatitis B surface antibody level ≥10 IU/L. Of 1,877 participants enrolled between 1989 and 2008, 441 (23%) were vaccinated prior to HIV diagnosis. Eighty percent of those who received vaccine doses only before HIV diagnosis had a positive vaccine response, compared with 66% of those who received doses both before and after HIV and 41% of those who received doses only after HIV (P < 0.01 for both compared with persons vaccinated before HIV only). Compared with the unvaccinated, persons vaccinated only before HIV had reduced risk of HBV infection after HIV diagnosis (hazard ratio = 0.38, 95% confidence interval: 0.20, 0.75). No reduction in HBV infection risk was observed for other vaccination groups. These data suggest that completion of the vaccine series prior to HIV infection may be the optimal strategy for preventing this significant comorbid infection in HIV-infected persons. PMID:21051446

Background Little is known about the incidence of anal HPV infection and related sequelae, and factors associated with these outcomes, among adolescents who are HIV-infected vs. uninfected but at-risk. Methods We analyzed data from a multisite U.S. study, the Reaching for Excellence in Adolescent Care and Health Project. Adolescents aged 12–18 years who were behaviorally HIV-infected (n=319) or HIV-uninfected but at-risk (n=177) were recruited. Incidence rates for anal HPV, high-risk anal HPV, anogenital warts, and anal dysplasia were calculated using Poisson modeling. Factors associated with these outcomes were examined using Cox proportional hazards modeling. Results Mean age at entry was 16.8 years; mean follow-up time for detection of anal HPV was 22.4 months (SD 10.8). Most participants (76%) were female; 70% were black non-Hispanic. HIV-infected (vs. –uninfected) women had significantly higher incidence of anal HPV (30 vs. 14 per 100 person-years; p=0.002), high-risk anal HPV (12 vs. 5.3 per 100 person-years; p=0.04), and anogenital warts (6.7 vs. 1.6 per 100 person-years; p=0.002) but not anal dysplasia. Although incidence rates were higher for these outcomes among HIV-infected vs. -uninfected men, the differences were not statistically significant. Among women, factors associated with anal HPV and related sequelae differed by HIV status and included biological, behavioral, and HIV-related factors. No factors were associated with outcomes in men. Conclusions HIV-infected vs. -uninfected adolescent women had higher rates of anal HPV and anogenital warts. Because HIV-infected youth are at increased risk of these outcomes, enhanced HPV prevention efforts, such as vaccination, are warranted for this group. PMID:23949587

Evaluation of a novel index case finding and linkage-to-care programme to identify and link HIV-infected children (1-15 years) and young persons (>15-24 years) to care. HIV-infected patients enrolled in HIV services were screened and those who reported untested household members (index cases) were offered home- or facility-based HIV testing and counselling (HTC) of their household by a community health worker (CHW). HIV-infected household members identified were enrolled in a follow-up programme offering home and facility-based follow-up by CHWs. Of the 1567 patients enrolled in HIV services, 1030 (65.7%) were screened and 461 (44.8%) identified as index cases; 93.5% consented to HIV testing of their households and of those, 279 (64.7%) reported an untested child or young person. CHWs tested 711 children and young persons, newly diagnosed 28 HIV-infected persons (yield 4.0%; 95% CI: 2.7-5.6), and identified an additional two HIV-infected persons not enrolled in care. Of the 30 HIV-infected persons identified, 23 (76.6%) were linked to HIV services; 18 of the 20 eligible for ART (90.0%) were initiated. Median time (IQR) from identification to enrolment into HIV services was 4 days (1-8) and from identification to ART start was 6 days (1-8). Almost half of HIV-infected patients enrolled in treatment services had untested household members, many of whom were children and young persons. Index case finding, coupled with home-based testing and tracked follow-up, is acceptable, feasible and facilitates the identification and timely linkage to care of HIV-infected children and young persons. © 2017 The Authors.

The study aimed to determine the prevalence of occult hepatitis B virus infection among HIV-infected persons and to evaluate the use of a pooling strategy to detect occult HBV infection in the setting of HIV infection. Five hundred and two HIV-positive individuals were tested for HBV, occult HBV and hepatitis C and D with serologic and nucleic acid testing (NAT). We also evaluated a pooled NAT strategy for screening occult HBV infection among the HIV-positive individuals. The prevalence of HBV infection among HIV-positive individuals was 32 (6.4%), and occult HBV prevalence was 10%. The pooling HBV NAT had a sensitivity of 66.7% and specificity of 100%, compared to HBV DNA NAT of individual samples. In conclusion, this study found a high prevalence of occult HBV infection among our HIV-infected population. We also demonstrated that pooled HBV NAT is highly specific, moderately sensitive and cost-effective. As conventional HBV viral load assays are expensive in resource-limited settings such as India, pooled HBV DNA NAT might be a good way for detecting occult HBV infection and will reduce HBV-associated complications. © 2018 John Wiley & Sons Ltd.

Objective Abacavir use has been associated with cardiovascular risk, but it is unknown whether this association may be partly explained by patients with kidney disease being preferentially treated with abacavir to avoid tenofovir. Our objective was to compare associations of abacavir and tenofovir with cardiovascular risks in HIV-infected veterans. Design Cohort study of 10 931 HIV-infected patients initiating antiretroviral therapy in the Veterans Health Administration from 1997 to 2007, using proportional hazards survival regression. Methods Primary predictors were exposure to abacavir or tenofovir within the past 6 months, compared with no exposure to these drugs, respectively. Outcomes were time to first atherosclerotic cardiovascular event, defined as coronary, cerebrovascular, or peripheral arterial disease; and time to incident heart failure. Results Over 60 588 person-years of observation, there were 501 cardiovascular and 194 heart failure events. Age-standardized event rates among abacavir and tenofovir users were 12.5 versus 8.2 per 1000 person-years for cardiovascular disease, and 3.9 and 3.7 per 1000 person-years for heart failure, respectively. In multivariate-adjusted models, including time-updated measurements of kidney function, recent abacavir use was significantly associated with incident cardiovascular disease [hazard ratio 1.48, 95% confidence interval (CI) 1.08–2.04]; the association was similar but nonsignificant for heart failure (1.45, 0.85–2.47). In contrast, recent tenofovir use was significantly associated with heart failure (1.82, 1.02–3.24), but not with cardiovascular events (0.78, 0.52–1.16). Conclusion Recent abacavir exposure was independently associated with increased risk for cardiovascular events. We also observed an association between recent tenofovir exposure and heart failure, which needs to be confirmed in future studies. PMID:21516027

The Fat of the Matter: Obesity and Visceral Adiposity in Treated HIV Infection.

The aim of this review is to summarize knowledge of the prevalence, relevant physiology, and consequences of obesity and visceral adiposity in HIV-infected adults, including highlighting gaps in current knowledge and future research directions. Similar to the general population, obesity prevalence is increasing among HIV-infected persons, and obesity and visceral adiposity are associated with numerous metabolic and inflammatory sequelae. However, HIV- and antiretroviral therapy (ART)-specific factors may contribute to fat gain and fat quality in treated HIV infection, particularly to the development of visceral adiposity, and sex differences may exist. Obesity and visceral adiposity commonly occur in HIV-infected persons and have significant implications for morbidity and mortality. Future research should aim to better elucidate the HIV- and ART-specific contributors to obesity and visceral adiposity in treated HIV infection, with the goal of developing targeted therapies for the prevention and treatment of obesity and visceral adiposity in the modern ART era.

A primary goal of the National HIV/AIDS Strategy is to reduce HIV-related health disparities, including HIV-related mortality in communities at high risk for human immunodeficiency virus (HIV) infection. As a group, persons who self-identify as blacks or African Americans (referred to as blacks in this report), have been affected by HIV more than any other racial/ethnic population. Forty-seven percent of persons who received an HIV diagnosis in the United States in 2012 and 43% of all persons living with diagnosed HIV infection in 2011 were black. Blacks also experienced a low 3-year survival rate among persons with HIV infection diagnosed during 2003-2008. CDC and its partners have been pursuing a high-impact prevention approach and supporting projects focusing on minorities to improve diagnosis, linkage to care, and retention in care, and to reduce disparities in HIV-related health outcomes. To measure trends in disparities in mortality among blacks, CDC analyzed data from the National HIV Surveillance System. The results of that analysis indicated that among blacks aged ≥13 years the death rate per 1,000 persons living with diagnosed HIV decreased from 28.4 in 2008 to 20.5 in 2012. Despite this improvement, in 2012 the death rate per 1,000 persons living with HIV among blacks was 13% higher than the rate for whites and 47% higher than the rate for Hispanics or Latinos. These data demonstrate the need for implementation of interventions and public health strategies to further reduce disparities in deaths.

Recent reports have indicated an increasing prevalence of HIV infection in the mentally ill. Reports have also emphasised the etiological role of HIV infection in psychiatric illness. The aim of this study was to assess the clinical and risk profile of psychiatric inpatients found seropositive for HIV infection. All psychiatric inpatients from a psychiatric hospital who tested positive for HI V infection over a five year period were assessed. The assessments included a detailed clinical history, psychiatric assessment and risk behaviour evaluation. Of the 2283 psychiatric patients tested, 51 were found to be seropositive. 43 patients were included in the study. 30 (69.7%) had a diagnosis of alcohol dependence, of which, 11 patients had comorbid psychiatnc diagnosis in the form of affective disorders (23%) and psychosis (14%). Personality disorders were seen in 9 patients. In 19% the clinical manifestation was considered to be etiologically related to HIV infection. The predominant risk behaviour was in the form of multiple partner heterosexual contacts. In several patients the risk behaviour had occurred during an episode of mental illness or under the influence of alcohol. The study demonstrates the importance of detecting and describing HIV infection and its manifestation among psychiatric patients. PMID:21430804

Currently, HIV is one of the most widely spread epidemics in the world. The specificity of the mode of transmission, the well-known severity of the prognosis, and the kind of therapies used are peculiarities of this illness. Personality traits of individuals with HIV may influence conditions for the infection itself. On the other hand, it is possible that personality traits may influence the course of the illness and the willingness of the patients to adhere to treatment. The present study assessed the personality traits of a heterogeneous group of seropositive subjects compared with healthy controls to determine specific temperament and character traits of this population. The Temperament and Character Inventory (TCI) was administered to 126 HIV-positive outpatients belonging to different risk categories for HIV infection and to a sample of healthy individuals matched for sex, age, and socioeconomic parameters. Drug-dependent HIV-positive patients displayed higher scores in novelty seeking and harm avoidance and lower scores in self-directedness compared with healthy controls. Non-drug-dependent HIV-positive subjects scored significantly higher in self-transcendence. Temperament and character features significantly differentiate the HIV-positive subjects from controls and those belonging to the different risk categories for HIV infection. Drug-dependent subjects with HIV display more impulsiveness, which possibly predates the HIV infection. They are also more fearful and lack self-directedness. Non-drug-dependent subjects express higher self-transcendence resources, possibly to overcome their difficulties. Both the temperament and character features may influence compliance with treatment and require specific interventions considering these subgroups.

To describe the incidence, the changes in the etiology and the prognosis of lower respiratory tract infection (LRTI) in HIV infected patients, presenting by the first time to the Emergency Department (ED), during years 2000-2010. Prospective collection of data. Data were collected on the first visit of HIV-infected patients at our ED due to a LRTI, (defined according to the criteria of the European Respiratory Society), between 1/1/2000 and 31/12/2010. A series of epidemiological and laboratory variables as well as the need for admission to the intensive care unit (ICU). LRTI etiology were also collected. The influence ofthe mentioned variables on 30-day mortality were analyzed. One hundred thirty one patients were included. LRTI represented 27% of visits to the ED by HIV-infected patients. Mean age was 39±9 years. 72% of patients were males. 18% required admission to the ICU. The most frequent LRTI was pneumonia by P. jiroveci in 35 cases, bacterial penumonia in 27 and pulmonary tuberculosis in 20. LRTI incidence gradually reduced significantly over time from 6.13 × 1000 patients/year in year 2000 to 0.23 × 1000 patients/year in 2010 (p<0.05). Overall mortality was 14%. Logistic regression analysis showed that admission to ICU (p<0.004) and viral load (p<0.029) were independent variables predicting mortality. LRTI is a pathology with a decreasing incidence, probably related to the widespread utilization increased of HAART regimens. lts etiology has also been changing, but with a non negligible mortality, mostly when ICU admission was required.

HIV-infected U.S. adults have reported internalized HIV-related stigma; however, the national prevalence of stigma is unknown. We sought to determine HIV-related stigma prevalence among adults in care, describe which socio-demographic groups bear the greatest stigma burden, and assess the association between stigma and sustained HIV viral suppression. The Medical Monitoring Project measures characteristics of U.S. HIV-infected adults receiving care using a national probability sample. We used weighted data collected from June 2011 to May 2014 and assessed self-reported internalized stigma based on agreement with six statements. Overall, 79.1% endorsed ≥1 HIV-related stigma statements (n = 13,841). The average stigma score was 2.4 (out of a possible high score of six). White males had the lowest stigma scores while Hispanic/Latina females and transgender persons who were multiracial or other race had the highest. Although stigma was associated with viral suppression, it was no longer associated after adjusting for age. Stigma was common among HIV-infected adults in care. Results suggest individual and community stigma interventions may be needed, particularly among those who are <50 years old or Hispanic/Latino. Stigma was not independently associated with viral suppression; however, this sample was limited to adults in care. Examining HIV-infected persons not in care may elucidate stigma's association with viral suppression.

To determine the prevalence and epidemiologic associations of Zika Virus (ZIKV) in HIV-infected patients in Ghana, West Africa. We examined the seroprevalence of ZIKV in HIV/HBV co-infected persons in Ghana from sera samples collected from 2012 to 2014 using ELISA assays and plaque reduction neutralization tests (PRNT). Overall, ZIKV antibody was detected in 12.9% of 236 tested samples, though the true estimate of exposure is probably less due cross-reactions with other related viruses. PRNTs were performed on a subset to provide an estimate of the frequency of false positive reaction. Dengue virus testing was also performed and antibody prevalence was 87.2%. The median CD4 count was 436 (range 2-1781 cell/mm) and did not affect antibody results. Regional geographic ethnicity was associated with ZIKV exposure. Overall, these data suggest that ZIKV infection is a relatively prevalent infection in HIV-positive persons in Ghana though not as common as dengue. Further evaluation of the effect of ZIKV and HIV co-infection is warranted given the large geographical overlap of populations exposed to both viruses.

Since 2006, CDC has recommended routine screening of all persons aged 13-64 years for human immunodeficiency virus (HIV) and at least annual rescreening of persons at higher risk (1). However, national surveillance data indicate that many persons at higher risk for HIV infection are not screened annually, and delays in diagnosis persist (2). CDC analyzed 2006-2016 data from the General Social Survey (GSS)* and estimated that only 39.6% of noninstitutionalized U.S. adults had ever tested for HIV. Among persons ever tested, the estimated median interval since last test was 1,080 days or almost 3 years. Only 62.2% of persons who reported HIV-related risk behaviors in the past 12 months were ever tested for HIV, and the median interval since last test in this group was 512 days (1.4 years). The percentage of persons ever tested and the interval since last test remained largely unchanged during 2006-2016. More frequent screening of persons with ongoing HIV risk is needed to achieve full implementation of CDC's screening recommendations and to prevent new infections. Integration of routine screening as standard clinical practice through existing strategies, such as electronic medical record prompts (3), or through new, innovative strategies might be needed to increase repeat screening of persons with ongoing risk.

What Can We Learn From Measles? No New HIV Infections.

Reducing the incidence of HIV infection until there are no new infections depends on driving the number of secondary infections produced by a typical source infection in a completely susceptible population (basic reproduction number; R0) down to less than 1. Components of R0 that must be addressed are the number of sexual contacts the infectious person makes per unit of time (C), the probability of transmission per single sexual contact with the infectious person (P), and the duration that the infected person is infectious to others (D) (R0 = C × P × D). Numerous strategies may contribute to driving transmission of HIV infection down to zero, including early initiation of antiretroviral treatment and pre- or postexposure prophylaxis.

Psychiatric disorders such as bipolar disorder, schizophrenia and depression have long been associated with risk behaviors for HIV, hepatitis C virus (HCV) and hepatitis B virus (HBV). The US prison population is reported to have elevated rates of HIV, hepatitis and most psychiatric disorders. This study examined the association of six major psychiatric disorders with HIV mono-infection, HIV/HCV co-infection and HIV/HBV co-infection in one of the nation's largest prison populations. The study population consisted of 370,511 Texas Department of Criminal Justice inmates who were incarcerated for any duration between January 1, 2003 and July 1, 2006. Information on medical conditions and sociodemographic factors was obtained from an institution-wide electronic medical information system. Offenders diagnosed with HIV mono-infection, HIV/HCV, HIV/HBV and all HIV combined exhibited elevated rates of major depression, bipolar disorder, schizophrenia, schizoaffective disorder, non-schizophrenic psychotic disorder and any psychiatric disorder. In comparison to offenders with HIV mono-infection, those with HIV/HCV co-infection had an elevated prevalence of any psychiatric disorder. This cross-sectional study's finding of positive associations between psychiatric disease and both HIV infection and hepatitis co-infection among Texas prison inmates holds both clinical and public health relevance. It will be important for future investigations to examine the extent to which psychiatric disorders serve as a barrier to medical care, communication with clinicians and adherence to prescribed medical regimens among both HIV-mono-infected and HIV/hepatitis-co-infected inmates.

Hepatic steatosis (HS) seems common in patients infected with human immunodeficiency virus (HIV). However, the relative effect of HIV, as well as hepatitis C virus (HCV) in those co-infected, and the influence of HS on liver fibrosis progression are unclear. The LIVEr disease in HIV (LIVEHIV) is a Canadian prospective cohort study using transient elastography and associated controlled attenuation parameter (CAP) to screen for HS and liver fibrosis, in unselected HIV-infected adults. HS progression was defined as development of any grade HS (CAP ⩾248dB/m), or transition to severe HS (CAP >292dB/m), for those with any grade HS at baseline. Fibrosis progression was defined as development of significant liver fibrosis (liver stiffness measurement [LSM] >7.1kPa), or transition to cirrhosis (LSM >12.5kPa) for those with significant liver fibrosis at baseline. Cox regression analysis was used to assess predictors of HS and fibrosis progression. A prospective cohort study was conducted, which included 726 HIV-infected patients (22.7% HCV co-infected). Prevalence of any grade HS did not differ between HIV mono-infected and HIV/HCV co-infected patients (36.1% vs. 38.6%, respectively). 313 patients were followed for a median of 15.4 (interquartile range 8.5-23.0) months. The rate of HS progression was 37.8 (95% confidence interval [CI] 29.2-49.0) and 21.9 (95% CI 15.6-30.7) per 100 person-years in HIV mono-infection and HIV/HCV co-infection, respectively. HCV co-infection was an independent negative predictor of HS progression (adjusted hazard ratio [aHR] 0.50, 95% CI 0.28-0.89). HS predicted liver fibrosis progression in HIV mono-infection (aHR 4.18, 95% CI 1.21-14.5), but not in HIV/HCV co-infection. HS progresses faster and is associated with liver fibrosis progression in HIV mono-infection but not in HIV/HCV co-infection.

Immigration is a recent phenomenon in Spain. Certain subgroups of the immigrant population may be vulnerable to acquiring sexually transmitted infections (STI). Descriptive study of the seroprevalenceof certain STI (HIV, hepatitis B and syphilis) and the general characteristicsn of persons tested for HIV infection in a specialized clinic in Barcelona during the year 2000. Seroprevalence of HIV was similar in immigrants and native residents(1.8% vs. 1.7% respectively). However, the seroprevalences of hepatitis B virus (anti-HBc) (19.5% vs. 8.3%) and syphilis (RPR 1 TPHA) (3.2% vs. 1.1%), as well as other STI and the practice of prostitution, were higher in immigrants. Several STI, including hepatitis B and syphilis, were found more frequently in immigrants than in the native population, whereas HIV seroprevalence was similar in the two groups.

Introduction Almost from the beginning of the HIV epidemic in 1981, an association with tuberculosis (TB) was recognized. This association between HIV and TB co-infection has been particularly evident amongst prisoners. However, despite this, few studies of TB in prisons have stratified results by HIV status. Given the high prevalence of HIV-positive persons and TB-infected persons in prisons and the documented risk of TB in those infected with HIV, it is of interest to determine how co-infection varies amongst prison populations worldwide. For this reason we have undertaken a systematic review of studies of co-infected prisoners to determine the incidence and/or prevalence of HIV/TB co-infection in prisons, as well as outcomes in this group, measured as treatment success or death. Methods A literature search was undertaken using the online databases PubMed, Embase, IBSS, Scopus, Web of Science, Global Health and CINAHL Plus. No restrictions were set on language or publication date for article retrieval, with articles included if indexed up to 18 October 2015. A total of 1975 non-duplicate papers were identified. For treatment and outcome data all eligible papers were appraised for inclusion; for incidence/prevalence estimates papers published prior to 2000 were excluded from full text review. After full text appraisal, 46 papers were selected for inclusion in the review, 41 for incidence/prevalence estimates and nine for outcomes data, with four papers providing evidence for both outcomes and prevalence/incidence. Results Very few studies estimated the incidence of TB in HIV positive prisoners, with most simply reporting prevalence of co-infection. Co-infection is rarely explicitly measured, with studies simply reporting HIV status in prisoners with TB, or a cross-sectional survey of TB prevalence amongst prisoners with HIV. Estimates of co-infection prevalence ranged from 2.4 to 73.1% and relative risks for one, given the other, ranged from 2.0 to 10.75, although

Toxoplasmosis in HIV infection: An overview

PubMed Central

Basavaraju, Anuradha

2016-01-01

Toxoplasma gondii is an obligate intracellular protozoan parasite presenting as a zoonotic infection distributed worldwide. In HIV-positive individuals, it causes severe opportunistic infections, which is of major public health concern as it results in physical and psychological disabilities. In healthy immunocompetent individuals, it causes asymptomatic chronic persistent infections, but in immunosuppressed patients, there is reactivation of the parasite if the CD4 counts fall below 200 cells/μl. The seroprevalence rates are variable in different geographic areas. The tissue cyst or oocyst is the infective form which enters by ingestion of contaminated meat and transform into tachyzoites and disseminate into blood stream. In immunocompetent persons due to cell-mediated immunity the parasite is transformed into tissue cyst resulting in life long chronic infection. In HIV-infected people opportunistic infection by T. gondii occurs due to depletion of CD4 cells, decreased production of cytokines and interferon gamma and impaired cytotoxic T-lymphocyte activity resulting in reactivation of latent infection. The diagnosis can be done by clinical, serological, radiological, histological or molecular methods, or by the combination of these. There is various treatment regimen including acute treatment, maintenance therapy should be given as the current anti T. gondii therapy cannot eradicate tissue cysts. In HIV patients, CD4 counts <100; cotrimoxazole, alternately dapsone + pyrimethamine can be given for 6 months. Hence, early diagnosis of T. gondii antibodies is important in all HIV-positive individuals to prevent complications of cerebral toxoplasmosis. PMID:27722101

Recent in vitro studies suggest that acyclovir may directly inhibit HIV-1 replication and can select for a specific HIV-1 reverse transcriptase mutation (V75I) with concomitant loss of an anti-HIV-1 effect. We tested for HIV-1 genotypic resistance at reverse transcriptase codon 75 in plasma from 168 HIV-1–infected persons from Botswana, Kenya, Peru, and the United States taking daily acyclovir or valacyclovir for between 8 weeks and 24 months. No V75I cases were detected (95% confidence interval, 0%–2.2%). These prospective in vivo studies suggest that standard-dose acyclovir or valacyclovir does not select for HIV-1 resistance.

Background There are limited data on opportunistic infections (OI) and factors associated with their occurrence after highly active antiretroviral therapy (HAART) in Asian children. The use of HAART in Asia started much later than in developed countries and therefore reported findings may not be fully applicable to the pediatric HIV epidemic in Asia. Methods Retrospective and prospectively collected data from the TREAT Asia Pediatric HIV Observational Database cohort study from March 1993 to March 2009 were analyzed. OIs were defined according to WHO clinical staging criteria, and incidence rates calculated. Factors associated with the incidence of severe OIs were analyzed using random effects Poisson regression modeling. Results Of 2280 children in the cohort, 1752 were ever reported to have received ART, of whom 1480 (84%) started on HAART. Before commencing any ART, OIs occurred at a rate of 89.5 per 100 person-years. The incidence rate was 28.8 infections per 100 person-years during mono- or dual-therapy, and 10.5 infections per 100 person-years during HAART. The most common OIs both before and after ART initiation were recurrent upper respiratory tract infections, persistent oral candidiasis, and pulmonary tuberculosis. The incidence rates of WHO clinical stage 3 or 4 OIs after HAART were highest among children <18 months of age and those with low weight-for-age z scores, CD4 cell percentage <15%, and WHO stage 3 at HAART initiation. Conclusions Despite dramatic declines in their incidence, OIs remained important causes of morbidity after HAART initiation in this regional cohort of HIV-infected children in Asia. PMID:24378942

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.

Background In HIV-positive people, sexually transmissible infections (STIs) probably increase the infectiousness of HIV. In 2010, we established a cohort of individuals (n=554) from clinics in the Australian HIV Observational Database (AHOD). We calculated retrospective rates for four STIs for 2005-10 and prospective incidence rates for 2010-11. At baseline (2010), patient characteristics were similar to the rest of AHOD. Overall incidence was 12.5 per 100 person-years. Chlamydial infections increased from 3.4 per 100 person-years (95% confidence interval (CI): 1.9-5.7) in 2005 to 6.7 per 100 person-years (95% CI: 4.5-9.5) in 2011, peaking in 2010 (8.1 per 100 person-years; 95% CI: 5.6-11.2). Cases were distributed among rectal (61.9%), urethral (34%) and pharyngeal (6.3%) sites. Gonococcal infections increased, peaking in 2010 (4.7 per 100 person-years; 95% CI: 5.6-11.2; Ptrend=0.0099), distributed among rectal (63.9%), urethral (27.9%) and pharyngeal (14.8%) sites. Syphilis showed several peaks, the largest in 2008 (5.3 per 100 person-years; 95% CI: 3.3-8.0); the overall trend was not significant (P=0.113). Genital warts declined from 7.5 per 100 person-years (95% CI: 4.8-11.3) in 2005 to 2.4 per 100 person-years (95% CI: 1.1-4.5) in 2011 (Ptrend=0.0016). For chlamydial and gonococcal infections, incidence was higher than previous Australian estimates among HIV-infected men who have sex with men, increasing during 2005-2011. Rectal infections outnumbered infections at other sites. Syphilis incidence remained high but did not increase; that of genital warts was lower and decreased.

To compare fracture risk in persons with and without HIV infection and to examine the influence of highly active antiretroviral therapy (HAART) initiation on risk of fracture. Population-based nationwide cohort study using Danish registries. Outcome measures were time to first fracture at any site, time to first low-energy and high-energy fracture in HIV-infected patients (n = 5306) compared with a general population control cohort (n = 26 530) matched by sex and age during the study period 1995-2009. Cox regression analyses were used to estimate incidence rate ratios (IRRs). HIV-infected patients had increased risk of fracture [IRR 1.5, 95% confidence interval (CI) 1.4-1.7] compared with population controls. The relative risk was lower in HIV-monoinfected patients (IRR 1.3, 95% CI 1.2-1.4) than in HIV/hepatitis C virus (HCV)-coinfected patients (IRR 2.9, 95% CI 2.5-3.4).Both HIV-monoinfected and HIV/HCV-coinfected patients had increased risk of low-energy fracture, IRR of 1.6 (95% CI 1.4-1.8) and 3.8 (95% CI 3.0-4.9). However, only HIV/HCV-coinfected patients had increased risk of high-energy fracture, IRR of 2.4 (95% CI 2.0-2.9). Among HIV-monoinfected patients the risk of low-energy fracture was only significantly increased after HAART exposure, IRR of 1.8 (95% CI 1.5-2.1). The increased risk in HAART-exposed patients was not associated with CD4 cell count, prior AIDS, tenofovir or efavirenz exposure, but with comorbidity and smoking. HIV-infected patients had increased risk of fracture compared with population controls. Among HIV-monoinfected patients the increased risk was observed for low-energy but not for high-energy fractures, and the increased risk of low-energy fracture was only observed in HAART-exposed patients.

Purpose. Hepatocellular carcinoma (HCC) is an increasing cause of mortality in HIV-infected patients in the highly active antiretroviral therapy (HAART) era. The aims of this study were to describe HCC tumor characteristics and different therapeutic approaches, to evaluate patient survival time from HCC diagnosis, and to identify clinical prognostic predictors in patients with and without HIV infection. Patients and Methods. A multicenter observational retrospective comparison of 104 HIV-infected patients and 484 uninfected patients was performed in four Italian centers. HCC was staged according to the Barcelona Clinic Liver Cancer (BCLC) criteria. Results. Tumor characteristics of patients with and without HIV were significantly different for age, Eastern Cooperative Oncology Group performance status (PS) score ≤1, and etiology of chronic liver disease. Despite the similar potentially curative option rate and better BCLC stage at diagnosis, the median survival time was significantly shorter in HIV+ patients. HIV+ patients were less frequently retreated at relapse. Independent predictors of survival were: BCLC stage, potentially effective HCC therapy, tumor dimension ≤3 cm, HCC diagnosis under a screening program, HCC recurrence, and portal vein thrombosis. Restricting the analysis to HIV+ patients only, all positive prognostic factors were confirmed together with HAART exposure. Conclusion. This study confirms a significantly shorter survival time in HIV+ HCC patients. The less aggressive retreatment at recurrence approach does not balance the benefit of younger age and better BCLC stage and PS score of HIV+ patients. Thus, considering the prognosis of HIV+ HCC patients, effective screening techniques, programs, and specific management guidelines are urgently needed. PMID:21868692

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. 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. 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/μl, 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). 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.

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.

Current antiretroviral therapy allows to achieve and sustain maximal suppression of HIV replication in most treated patients. As result, the life expectancy of HIV-infected persons has improved dramatically and is nowadays similar to that of the HIV-negative population. However, oral antiretrovirals have to be taken daily and indefinitely to avoid resumption of HIV replication and selection of drug resistance. Unfortunately, drug adherence is often suboptimal and tends to decline over time. Areas covered: New drugs, formulations and delivery systems are being developed for extended-release of antiretrovirals. At this time, intramuscular cabotegravir and rilpivirine, dapivirine vaginal rings and tenofovir alafenamide subdermal implants are the products in more advanced stages of clinical development. Their pharmacokinetics/dynamics and safety/efficacy are reviewed. Expert commentary: In the absence of eradicative therapy for individuals with HIV infection and protective vaccines for persons at risk, long-term antiretroviral therapy is the best approach for preventing disease progression in patients and halting transmissions, either as result of 'treatment as prevention' for HIV carriers or 'pre-exposure prophylaxis' for uninfected individuals at risk. In all these scenarios, the advent of long-acting antiretrovirals will expand options for overcoming the challenge of suboptimal drug adherence and reduce the burden of HIV infection.

increased the relative HIV diagnostic yield (both established and acute HIV infections) by 10.4% (95% CI, 8.8%-12.2%) and pooled HIV RNA testing increased the relative HIV diagnostic yield by 12.4% (95% CI, 10.7%-14.3%). In a high-prevalence population, HIV screening using an HIV Ag/Ab combination assay following a negative rapid test detected 82% of acute HIV infections detectable by pooled HIV RNA testing, with a positive predictive value of 59%. Further research is needed to evaluate this strategy in lower-prevalence populations and in persons using preexposure prophylaxis for HIV prevention.

Preexposure prophylaxis with antiretroviral drugs has been effective in the prevention of human immunodeficiency virus (HIV) infection in some trials but not in others. 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. 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. 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.).

Immunology of Pediatric HIV Infection

2013-01-01

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.

Formation of Personal HIV Disclosure Policies among HIV-Positive Men Who Have Sex with Men

PubMed Central

2009-01-01

Abstract Given the increasing emphasis on “prevention with positives” programs designed to promote HIV transmission risk reduction among people living with HIV/AIDS, better understanding of influences upon serostatus disclosure in sexual situations is needed. Based on grounded theory analyses of individual interviews, this exploratory research hypothesizes and interprets how 15 HIV-positive men who have sex with men (MSM) formed personal HIV disclosure policies for sexual situations. Participants described five elements influencing development of their personal policies, including: (1) making sense of having been infected, (2) envisioning sex as an HIV-positive man, (3) sorting through feelings of responsibility for others, (4) responding to views of friends and the gay community, and (5) anticipating reactions and consequences of disclosure. The article concludes with implications for current initiatives for prevention with positives. PMID:19621994

"Depression (as noted in chart by a physician)" was compared between HIV infected pregnant women and controls. Perinatally HIV-infected (PHIV), non-perinatally HIV-infected (NPHIV), and HIV-uninfected (HIV-U) pregnant women were all compared using a logistic regression model. Overall, HIV-infected women had higher rates of depression than HIV-U, with PHIV women demonstrating a clinically and statistically significant increased risk compared to HIV-U women [adjusted OR: 15.9, 95% CI = 1.8-143.8]. Future studies in larger populations are warranted to confirm these findings and further elucidate mental health outcomes of PHIV and NPHIV pregnant women.

Few studies have addressed primary human immunodeficiency virus (HIV) type 1 infection in sub-Saharan Africa, where the epidemic is of a predominantly heterosexual character and is caused by different subtypes. The present study examines the dynamics of viral replication in subjects infected with various HIV-1 subtypes. Seven hundred fifty-two HIV-negative Senegalese women at high risk for infection were monitored every 3 months for acute/early HIV infection; 26 infections were identified (23 HIV-1 and 3 HIV-2), with an HIV-1 incidence rate of 3.23 cases/person-years observation. Multiple viral-load measurements were taken for all seroconverters. The mean+/-standard deviation viral load for all subjects during the early stage of infection was 4.13+/-0.66 log10 copies/mL, with an overall decrease of 0.22 log10 copies/mL after the early stage; the viral set point was reached after 12 months of infection. Most subjects had relatively low viral loads during the early stage of infection. HIV-1 CRF02_AG-infected women had a significantly higher mean viral load during the early stage of infection (mean +/- SD, 4.45+/-0.60 log(10) copies/mL) than did non-HIV-1 CRF02_AG-infected women (mean+/-SD, 3.78+/-0.46 log(10) copies/mL) (P=.008). None of the subjects reported symptoms consistent with primary HIV-1 infection. Our findings in Senegalese women differ from what have been described for primary HIV-1 infection. Further investigations of primary infections with non-B subtypes are warranted, to better characterize their differences with primary infections with subtype B.

Clinical implications of aging with HIV infection: perspectives and the future medical care agenda.

Guaraldi, Giovanni; Palella, Frank J

: The increasing number of aging HIV-infected (HIV+) persons comprises a unique population at risk for illnesses and syndromes traditionally associated with the elderly. As a result, similar to the current need for primary care providers to manage chronic noninfectious comorbidities among aging persons with well controlled HIV infection, HIV clinical care will need to routinely involve geriatric medicine in a new HIV-geriatric discipline. The objective of this article is to provide a conceptual framework in which HIV and geriatric management considerations for healthcare professionals caring for HIV+ persons are integrated. The provision of contemporary HIV clinical care extends well beyond the achievement of HIV virologic suppression and antiretroviral therapy management and includes a need for careful characterization of geriatric syndromes based upon functional capacity and extent of disability. Screening for geriatric syndromes is both a multidisciplinary and multidimensional process, designed to evaluate an older person's functional ability, physical health, cognition, overall mental health, and socio-environmental circumstances. Although routine incorporation of geriatric assessment into clinical trials involving HIV+ persons is feasible, a current challenge is the availability of a consensus clinical definition of frailty or vulnerability. To maximize the efficiency, value, and convenience of outpatient care visits for older HIV+ persons, these visits should include encounters with multiple providers, including primary care clinicians, social workers, and geriatricians. Challenges may exist in the routine provision of these assessments to older HIV+ persons, but clearly such cross-disciplinary collaboration will not only markedly enhance the care of aging HIV+ persons but may also constitute a model of successful healthcare management that can be applied to all aging persons with changing healthcare needs.

Limited information is available to describe the molecular epidemiology of HIV-1 in Bulgaria. To better understand the genetic diversity and the epidemiologic dynamics of HIV-1 we analyzed 125 new polymerase (pol) sequences from Bulgarians diagnosed through 2009 and 77 pol sequences available from our previous study from persons infected prior to 2007. Epidemiologic and demographic information was obtained from each participant and phylogenetic analysis was used to infer HIV-1 evolutionary histories. 120 (59.5%) persons were infected with one of five different HIV-1 subtypes (A1, B, C, F1 and H) and 63 (31.2%) persons were infected with one of six different circulating recombinant forms (CRFs; 01_AE, 02_AG, 04_cpx, 05_DF, 14_BG, and 36_cpx). We also for the first time identified infection with two different clusters of unique A-like and F-like sub-subtype variants in 12 persons (5.9%) and seven unique recombinant forms (3.5%), including a novel J/C recombinant. While subtype B was the major genotype identified and was more prevalent in MSM and increased between 2000–2005, most non-B subtypes were present in persons ≥45 years old. CRF01_AE was the most common non-B subtype and was higher in women and IDUs relative to other risk groups combined. Our results show that HIV-1 infection in Bulgaria reflects the shifting distribution of genotypes coincident with the changing epidemiology of the HIV-1 epidemic among different risk groups. Our data support increased public health interventions targeting IDUs and MSM. Furthermore, the substantial and increasing HIV-1 genetic heterogeneity, combined with fluctuating infection dynamics, highlights the importance of sustained and expanded surveillance to prevent and control HIV-1 infection in Bulgaria.

Tijuana, Mexico, just south of San Diego, California, is located by the busiest land border crossing in the world. Although UNAIDS considers Mexico to be a country of "low prevalence, high risk," recent surveillance data among sentinel populations in Tijuana suggests HIV prevalence is increasing. The aim of this study was to estimate the number of men and women aged 15 to 49 years infected with HIV in Tijuana. Gender and age-specific estimates of the Tijuana population were obtained from the 2000 Mexican census. Population and HIV prevalence estimates for at-risk groups were obtained from published reports, community based studies, and data from the Centro Nacional para la Prevención y Control del VIH/SIDA (CENSIDA). Age-specific fertility rates for Mexico were used to derive the number of low and high-risk pregnant women. Numbers of HIV-positive men and women were estimated for each at-risk group and then aggregated. A high growth scenario based on current HIV prevalence and a conservative, low growth estimate were determined. A total of 686,600 men and women in Tijuana were aged 15 to 49 years at the time of the 2000 census. Considering both scenarios, the number of infected persons ranged from 1,803 to 5,472 (HIV prevalence: 0.26 to 0.80%). The majority of these persons were men (>70%). The largest number of infected persons were MSM (N = 1,146 to 3,300) and IDUs (N = 147 to 650). Our data suggest that up to one in every 125 persons aged 15-49 years in Tijuana is HIV-infected. Interventions to reduce ongoing spread of HIV are urgently needed.

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 American Society of Tropical Medicine and Hygiene.

We have examined human immunodeficiency virus type 1 (HIV-1) infection in chimpanzees by analyzing HIV-1 DNA and RNA in lymph nodes and peripheral mononuclear cells (PBMCs). Like certain asymptomatic HIV-infected persons, these chimpanzees had no detectable viral replication in their PBMCs. However, viral replication and a high viral load were observed in the lymphatic tissue. Despite the absence of viral replication in PBMCs, 1/1,000 to 1/10,000 of the PBMCs contained HIV-1 proviral DNA, and HIV transcription could be rapidly induced in these cells in vitro. These results provide direct evidence of cellular latency of HIV in vivo and suggest that HIV infection in chimpanzees may be a useful model for clinical latency of HIV infection in humans.

Hepatitis B and HIV infections are endemic in sub-Saharan Africa including Ghana. Understanding the extent of the co-infection is critical to the optimal care of persons living with HIV and AIDS (PLHIV). We determined the prevalence and risk factors of HBV co-infection in PLHIV and assessed the knowledge of health care workers (HCW) in Antiretroviral Therapy (ART) clinics regarding the co-infection. A cross sectional study was conducted in five ART clinics to obtain data from a systematic random sample of PLHIV in the Eastern region of Ghana from March to June 2012. We used self-administered questionnaires to assess knowledge of HCW on knowledge and management of the co-infection. Descriptive statistics and logistic regression models were used for analysis at 5% significance level. Of 320 PLHIV recruited into study, with median age of 40 years (IQR: 33-50 years), 28 tested positive for HBsAg giving an overall prevalence of 8.8%. There were significant associations between HBV infection and being an adult (p=0.004), increasing serum ALT levels (p=0.002) and partner with history of HBV infection (p=0.010). HCW obtained 84.2% (SD± 20.53; 95% CI: 89-98.1) and 53.1% (SD± 35.06; 95% CI: 13.0-88.9) in the "general knowledge" and "management practice" indexes respectively. Prevalence of HBV-HIV co-infection was relatively high among PLHIV in Eastern region. Knowledge of HCW on management practices of HBV-HIV co-infection and HBV vaccination coverage among PLHIV were found to be relatively low. Regular trainings of HCW and a HBV vaccination programme targeted at PLHIV should be considered.

In individuals with latent tuberculosis (TB) infection, those living with human immunodeficiency virus (HIV) had a 20-37 times higher risk of developing active TB compared to those without HIV infection. Systematic testing and treatment of latent TB infection are priorities in HIV-infected persons. In China, the prevalence of HIV infection in men who have sex with men (MSM) has gradually increased in the past decade. However, the prevalence of TB infection has been studied sparsely in HIV-infected MSM. Hence, we conducted a pilot study in MSM living with HIV infection in Xi'an city to evaluate TB infection status by means of interferon-γ release assay (IGRA). A total of 182 HIV-infected MSM were included in this study, the prevalence of IGRA positivity was observed to be 8·79% (16/182). IGRA quantitative results were not statistically influenced by the CD4 cell counts of the study participants. However, IGRA positivity was found to be lower than our previously reported data from the general population. This suggests that immunological deficiency might decrease the sensitivity of IGRA and thus increase the number of false negatives. Our primary results, suggesting systematic testing and treatment of latent TB infection together with active case-finding, were equally important for TB control in persons living with HIV infection.

The purpose of the study was to estimate the number of injection drug users infected with the human immunodeficiency virus (HIV) in Bangkok to allow planning for health services for this population. A two-sample capture-recapture method was used. The first capture listed all persons on methadone treatment for opiate addiction from April 17 through May 17, 1991, at 18 facilities in Bangkok. The second capture involved urine testing of persons held at 72 Bangkok police stations from June 3 through September 30, 1991. Persons whose urine tests were positive for opiate metabolites or methadone were included on the second list. The first capture comprised 4064 persons and the recapture 1540 persons. There were 171 persons included on both lists, yielding an estimate of 36,600 opiate users in Bangkok. Existing data indicate that 89% of opiate users in Bangkok inject drugs and that about one third are infected with HIV, yielding an estimate of approximately 12,000 HIV-infected injection drug users in Bangkok in 1991. During the 1990s the number of cases of acquired immunodeficiency syndrome (AIDS) and other HIV-related diseases, including tuberculosis, in the population of HIV-infected injection drug users in Bangkok will increase dramatically, placing new demands on existing health care facilities. The capture-recapture method may be useful in estimating difficult-to-count populations, including injection drug users.

The study investigated the impact of xerostomia on oral health and quality of life (QoL) among patients infected with human immunodeficiency virus (HIV) who were attending for routine HIV monitoring in Australia. This cross-sectional, self-administered questionnaire survey and oral screening (OS) included 100 subjects who were HIV positive. The OS was conducted by a dentist blinded to the subject's survey responses. Xerostomia was determined by asking the subjects a single question. Subjects with xerostomia were found to have increased caries activity and poorer QoL, especially in the psychological dimensions of the oral health impact profile. Age and duration of HIV infection were associated with xerostomia. Early diagnosis of xerostomia and intervention with preventive dental care would potentially reduce caries and improve QoL among patients infected with HIV-1. Ongoing chronic inflammation of salivary glands despite the beneficial effects of antiretroviral therapy may play a role in the etiology of xerostomia in patients infected with HIV and requires further study. © 2012 Special Care Dentistry Association and Wiley Periodicals, Inc.

Respect for persons permits prioritizing treatment for HIV/AIDS.

PubMed

Metz, Thaddeus

2008-08-01

I defend a certain claim about rationing in the context of HIV/AIDS, namely the 'priority thesis' that the state of a developing country with a high rate of HIV should provide highly active anti-retroviral treatment (HAART) to those who would die without it, even if doing so would require not treating most other life-threatening diseases. More specifically,I defend the priority thesis in a negative way by refuting two influential and important arguments against it inspired by the Kantian principle of respect for persons. The 'equality argument' more or less maintains that prioritizing treatment for HIV/AIDS would objectionably treat those who suffer from it as more important than those who do not. The 'responsibility argument' says, roughly, that to ration life-saving treatment by prioritizing those with HIV would wrongly fail to hold people responsible for their actions, since most people infected with HIV could have avoided the foreseeable harm of infection. While it appears that a Kantian must think that one of these two arguments is sound, I maintain that, in fact, respect for persons grounds neither the equality nor responsibility argument against prioritizing HAART and hence at least permits doing so. If this negative defence of the priority thesis succeeds, then conceptual space is opened up for the possibility that respect for persons requires prioritizing HAART which argument I sketch in the conclusion as something to articulate and defend in future work.

HIV-1-infected patients are surviving longer and by 2015 half will be older than 50 years of age. Frailty is a syndrome associated with advanced age but occurs in HIV-1-infected patients at younger ages. One hundred outpatient HIV-1-infected persons were prospectively tested for clinical markers of frailty: shrinking weight, slowness in walking, decrease in grip strength, low activity, and exhaustion. Age, length of infection with HIV, CD4 count, HIV-1 RNA, and comorbidities were compared. CD4 counts <200 cells/mm(3) were associated with 9-fold increased odds of frailty relative to patients with a CD4 count >350 cells/mm(3) (odds ratio [OR] 9.0, 95% confidence interval [CI] 2.1-44). Seven frail patients were measured 6 months later: 2 died refusing therapy, 4 were no longer frail, and 1 patient remained frail. We conclude that frailty is common in HIV outpatients and is associated with low CD4 counts. However, our data suggest that frailty is transient, especially in younger patients who may revert to their prefrail state unlike uninfected elderly individuals in whom a stepwise decline in function occurs.

In 2003, the Centers for Disease Control and Prevention launched the Advancing HIV Prevention project to implement new strategies for diagnosing human immunodeficiency virus (HIV) infections outside medical settings and prevent new infections by working with HIV-infected persons and their partners. : To assess the cost and effectiveness of a social network strategy to identify new HIV diagnoses among minority populations. Four community-based organizations (CBOs) in Boston, Philadelphia, and Washington, District of Columbia, implemented a social network strategy for HIV counseling and testing from October 2003 to December 2005. We used standardized cost collection forms to collect program costs attributable to staff time, travel, incentives, test kits, testing supplies, office space, equipment, and utilities. The CBOs used the networks of high-risk and HIV-infected persons (recruiters) who referred their partners and associates for HIV counseling and testing. We obtained HIV-testing outcomes from project databases. Number of HIV tests, number of new HIV-diagnoses notified, total program cost, cost per person tested, cost per person notified of new HIV diagnosis. Two CBOs, both based in Philadelphia, identified 25 and 17 recruiters on average annually and tested 136 and 330 network associates, respectively. Among those tested, 12 and 13 associates were notified of new HIV diagnoses (seropositivity: 9.8%, 4.4%). CBOs in Boston, Massachusetts, and Washington, District of Columbia, identified 26 and 24 recruiters per year on average and tested 228 and 123 network associates. Among those tested, 12 and 11 associates were notified of new HIV diagnoses (seropositivity: 5.1%, 8.7%). The cost per associate notified of a new HIV diagnosis was $11 578 and $12 135 in Philadelphia, and $16 437 and $16 101 in Boston, Massachusetts, and Washington, District of Columbia. The cost of notifying someone with a new HIV diagnosis using social networks varied across sites. Our analysis

Both HIV and HBV infection have become major health problems, of global concern, due to the high prevalence in the past few decades. Data from cumulated epidemiological surveys have shown the links between maternal HIV or HBV infection and adverse outcomes on pregnancy. Maternal HIV or HBV infection may also increase the mother-to-child (MTCT) transmission of the two diseases. However, association between HIV-HBV co-infection and adverse pregnancy is still inconclusive. Does maternal HIV-HBV co-infection have an impact on mother-to-child transmission on either HIV or HBV? Study on effective precautionary measures to promote both maternal and child's health is deemed necessary.

Disparities in HIV infection, with females having higher rates of HIV infection than males, have been noted among persons who inject drugs (PWID) in many countries. We examined male/female HIV disparities among PWID in Central Asia and compared these disparities with patterns worldwide. A systematic review and meta-analyses were conducted for studies reporting HIV prevalence by gender among PWID. To be included in the analyses, reports had to contain (1) samples of PWID from Central Asia, (2) HIV data based on laboratory testing, (3) HIV prevalence reported for males and females, and (4) samples that were not recruited on the basis of HIV status. Data were abstracted from 11 studies in 5 countries in Central Asia: China, Kazakhstan, Russia, Tajikistan, and Uzbekistan; the total sample size was 12,225. The mean weighted OR for HIV prevalence among females to males was 0.913 (95% CI 0.07, 1.26), with high heterogeneity among studies (I(2)=70.0%) and a possible publication bias among studies with small sample sizes (Eggers test=-1.81, 95% CI -5.18, 0.54). The non-significant higher HIV prevalence among male PWID in Central Asia contrasts with the worldwide findings which show slightly higher HIV prevalence among female PWID. This may reflect the relative recency of the HIV epidemics in Central Asia. The findings also suggest there may be factors that protect female PWID from HIV in some settings. Further examination of transmission dynamics in Central Asia is necessary to better understand the HIV epidemic among PWID. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

To determine the incidence of nosocomial infections (NI) in HIV-infected patients and to analyse some of the associated risk factors. Multicentre prospective study on consecutive HIV-infected patients admitted to 19 Italian acute-care infectious disease wards. All patients admitted during a 1-year period were followed-up for NI until their discharge. Univariate and multivariate analyses were performed for NI risk factors. As of June 1998 a total of 344 NI occurred in 4330 admissions, with at least one NI in 273 admissions (6.3%). The incidence rate of NI was 3.6 per 1000 patient days [95% confidence interval (CI), 3.2-4.1]. Overall distribution by site was 36.6% bloodstream infections (BSI), 30.5% urinary tract infections, 18.4% pneumonia, 5.2% skin/soft tissue infections, 2.0% surgical wound infections and 7.3% others. Fifty-five out of the 126 BSI were related to a central venous catheter (CVC); the rate of CVC-associated infections was eight infections per 1000 devices. At multivariate analysis, variables independently associated with NI included CD4 T-lymphocyte count < 200 x 10(6)/l [odds ratio (OR), 2.21; 95% CI, 1.35-3.62], Karnofsky Performance Status < 40 (OR, 1.89; 95% CI, 1.28-2.78), therapy with corticosteroids (OR, 1.78; 95% CI, 1.29-2.45), CVC (OR, 3.24; 95% CI, 2.41-4.35), urinary catheter (OR, 6.53; 95% CI, 4.81-8.86) and surgery (OR, 3.13; 95% CI, 1.90-5.15). Results suggest that NI occur commonly in HIV-infected patients. As the number of cases of HIV continues to increase, the number of HIV-infected patients requiring hospitalization may also increase. Clinicians need to be aware of the risk factors for NI and must consider these infections in the overall management of HIV-infected, hospitalized patients.

Human immunodeficiency virus (HIV)-infected persons have an elevated risk for lung cancer, but whether the increase reflects solely their heavy tobacco use remains an open question. The Acquired Immunodeficiency Syndrome (AIDS) Link to the Intravenous Experience Study has prospectively observed a cohort of injection drug users in Baltimore, Maryland, since 1988, using biannual collection of clinical, laboratory, and behavioral data. Lung cancer deaths were identified through linkage with the National Death Index. Cox proportional hazards regression was used to examine the effect of HIV infection on lung cancer risk, controlling for smoking status, drug use, and clinical variables. Among 2086 AIDS Link to the Intravenous Experience Study participants observed for 19,835 person-years, 27 lung cancer deaths were identified; 14 of the deaths were among HIV-infected persons. All but 1 (96%) of the patients with lung cancer were smokers, smoking a mean of 1.2 packs per day. Lung cancer mortality increased during the highly active antiretroviral therapy era, compared with the pre-highly active antiretroviral therapy period (mortality rate ratio, 4.7; 95% confidence interval, 1.7-16). After adjusting for age, sex, smoking status, and calendar period, HIV infection was associated with increased lung cancer risk (hazard ratio, 3.6; 95% confidence interval, 1.6-7.9). Preexisting lung disease, particularly noninfectious diseases and asthma, displayed trends for increased lung cancer risk. Illicit drug use was not associated with increased lung cancer risk. Among HIV-infected persons, smoking remained the major risk factor; CD4 cell count and HIV load were not strongly associated with increased lung cancer risk, and trends for increased risk with use of highly active antiretroviral therapy were not significant. HIV infection is associated with significantly increased risk for developing lung cancer, independent of smoking status.

HIV infection is associated with increased risk of coronary heart disease beyond that explained by traditional risk factors, and altered gut microbiota has been proposed as a potential trigger. Trimethylamine-N-oxide (TMAO) is a proatherogenic substance formed in the liver from trimethylamine, exclusively generated by gut microbiota from dietary phosphatidylcholine. We aimed to investigate whether TMAO is associated with subclinical and clinical coronary heart disease in HIV infection. Two previously described cohorts were examined as follows: (1) cross-sectional cohort of HIV-infected persons and uninfected controls with known atherosclerotic plaque burden as assessed by myocardial perfusion scintigraphy, coronary artery calcium score, and intima-media thickness and (2) nested case-control study of HIV-infected persons with first-time myocardial infarction (MI) compared with HIV-infected persons without MI, assessed at 4 time points from before initiation of antiretroviral therapy (ART) to last sample before the case's MI (median: 51, range: 0-239 days). There was no difference in plasma TMAO when comparing HIV-infected persons and uninfected controls. TMAO was elevated in HIV-infected persons with myocardial perfusion defects but was not associated with coronary artery calcium score, intima media thickness, or Framingham risk score. In the nested case control study, plasma TMAO was not associated with first-time MI. However, TMAO increased after ART introduction and was associated with the use of protease inhibitors in both cohorts. TMAO was elevated in HIV-infected persons with myocardial perfusion defects, but was not associated with first-time MI. Our data question TMAO as a useful biomarker of cardiovascular risk in HIV infection, at least in ART-treated individuals.

Despite the introduction of campaigns to prevent the continued spread of HIV/AIDS in Germany, the number of annual firsttime HIV-diagnoses is continuing steadily. The concepts behind the current campaigns are largely based on models of New Public Health, of which social learning strategies are an essential element. The established personal and individual rights should be unimpeachable but the right not to know the status of HIV infection should be questioned for those people who spread their HIV infection intentionally and wilfully. Confronted with more than 10,000 people in Germany unconscious of their HIV infection, easy access to HIV testing and access of opportune therapy should be offered with the goal of reducing the number of new infections. Expanded strategies on the responsibility to one's personal health and that of the partner, understandable and adapted to special groups of the society, should be established and maintained at a high level of awareness. All measures must be performed voluntarily.

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.

Rodríguez-Muñoz, Jesús; Moreno, Santiago

The disadvantages of the long-term administration of antiretroviral therapy as well as the huge number of affected persons have placed the cure of HIV as a primary goal of Public Health. HIV may persist in the organism by at least four mechanisms: a latently infected cellular reservoir, the persistent replication of HIV in spite of ART, anatomic sanctuaries, and the immune dysfunction. Several strategies directed against these mechanisms have been developed. With all this, a complete eradication of HIV has been achieved in a patient using the transplantation of haemopoietic stem cells that were resistant to HIV-infection, and there are examples of functional cure either spontaneously (elite controllers) or after antiretroviral therapy (post-treatment controllers). However, no strategies have been successful in reducing the reservoir size, nor in achieving constant, uniform remissions. The failure of isolated strategies makes it likely that the combination of several of them may be the future solution.

Individuals infected with HIV experience numerous comorbidities caused by the disease progression and medications, lack of (or inability to perform) physical activity, malnutrition, or a combination of these causes. Common symptoms include loss of muscle mass, fatigue, lypodystrophy, lypoatrophy, and decreases in strength, functional capacity, and overall quality of life. Studies have shown that exercise is a potential treatment of many of these symptoms. Research suggests that exercise may produce beneficial physiological changes in the HIV-infected population such as improved body composition and increases in both strength and endurance. In addition, psychological conditions such as depression and anxiety have been shown to be positively affected by exercise. The purpose of this review is to examine the literature regarding effects of aerobic, resistance, and combined aerobic and resistance exercise training on HIV-infected individuals.

We have previously reported that persons co-infected with HIV and hepatitis C virus (HCV) had liver disease stages similar to HIV-uninfected individuals who were approximately 10 years older. Insulin-like growth factor 1(IGF-1) levels have long been known to decline with advancing age in humans and non-humans alike. We examined whether HIV infection affects the expected decline in IGF-1 in persons with chronic hepatitis C virus (HCV) infection and if that alteration in IGF-1 decline contributes to the link between HIV, aging, and liver disease progression. A total of 553 individuals with HCV infection were studied from the AIDS Linked to the Intravenous Experience (ALIVE) cohort for whom more than 10 years of follow-up was available. Serum IGF-1 levels were determined by ELISA and evaluated according to baseline characteristics and over time by HIV status and liver disease progression. Linear regression with generalized estimating equations was used to determine whether IGF-1 decline over time was independently associated with liver disease progression. Baseline IGF-1 levels were strongly associated with age ( P < 0.0001) but not with gender or HIV infection. Levels of IGF-1 declined at a rate of -1.75 ng/mL each year in HCV mono-infected individuals and at a rate of -1.23 ng/mL each year in HIV/HCV co-infected individuals ( P < 0.05). In a multivariable linear regression model, progression of liver fibrosis was associated with HIV infection and age, as well as with a slower rate of IGF-1 decline ( P = 0.001); however, the rate of IGF-1 decline did not alter the strength of the associations between HIV, liver disease, and age. The normal decline in IGF-1 levels with age was attenuated in HIV/HCV co-infected individuals compared to those with HCV mono-infection, and slower IGF-1 decline was independently associated with liver disease progression.

This study aimed to determine changes in fertility intentions of HIV-1 infected and uninfected reproductive age women in Blantyre, Malawi. Participants were asked about their fertility intentions at baseline and at 3-month visits for 1 year. Time-to-event statistical models were used to determine factors associated with changes in fertility intentions. Overall, 842 HIV uninfected and 844 HIV infected women were enrolled. The hazard of changing from wanting no more children at baseline to wanting more children at follow-up was 61% lower among HIV infected women compared to HIV uninfected women (P < 0.01) after adjusting for other factors, while HIV infected women were approximately 3 times more likely to change to wanting no more children. The overall pregnancy rate after 12 months was 14.9 per 100 person-years and did not differ among 102 HIV uninfected and 100 infected women who became pregnant. HIV infection is a significant predictor of fertility intentions over time.

 In the Strategic Timing of Antiretroviral Treatment (START) study, immediate combination antiretroviral therapy (cART) initiation reduced cancer risk by 64%. We hypothesized that risk reduction was higher for infection-related cancer and determined by differences in CD4 cell counts and human immunodeficiency virus (HIV) RNA between the study arms.  Incident malignancies in START were categorized into infection-related and infection-unrelated cancer. We used Cox models to assess factors associated with both cancer categories. We used sequential adjustment for baseline covariates, cancer risk factors, and HIV-specific variables to investigate potential mediators of cancer risk reduction with immediate cART.  There were 14 cancers among persons randomized to immediate cART (6 infection-related and 8 infection-unrelated) and 39 cancers in the deferred arm (23 infection-related and 16 infection-unrelated); hazard ratios of immediate vs deferred cART initiation were 0.26 (95% confidence interval [CI], .11-.64) for infection-related and 0.49 (95% CI, .21-1.15) for infection-unrelated cancer. Independent predictors of infection-related cancer were older age, higher body mass index, low- to middle-income region, HIV RNA, and baseline CD8 cell count. Older age and baseline CD8 cell count were independent predictors of infection-unrelated cancer. Adjustment for latest HIV RNA level had little impact on the protective effect of immediate cART on infection-related cancer. Adjustment for latest HIV RNA level, but not for CD4 cell count or cancer risk factors, attenuated the effect of immediate cART on infection-unrelated cancer.  Immediate cART initiation significantly reduces risk of cancer. Although limited by small sample size, this benefit does not appear to be solely attributable to HIV RNA suppression and may be also mediated by other mechanisms. © The Author 2016.

This study brings together the literature on social network approaches to social capital and health and on migration and HIV risks to examine how non-migrating wives of labor migrants use their personal networks to cope with perceived risks of HIV infection in rural southern Mozambique. Using data from a 2006 survey of 1,680 women and their dyadic interactions, we compare the composition of personal networks, HIV/AIDS communication, and preventive behavior of women married to migrants and those married to non-migrants. Results show that migrants’ wives were more likely than non-migrants’ wives to have other migrants’ wives as personal network members, to engage in HIV/AIDS communication, and to discuss HIV prevention. However, they were no more likely to talk about HIV/AIDS with migrants’ wives than with non-migrants’ wives. They were also no more likely to talk about AIDS and its prevention than non-migrants’ wives who express worry about HIV infection from their spouses. Finally, we detect that network members’ prevention behavior was similar to respondents’, although this did not depend on migration. We contextualize these findings within the literature and discuss their policy implications. PMID:23466827

One quarter of pregnant women in Zambia are infected with HIV. Understanding how knowledge of HIV relates to personal risk perception and avoidance of risky behaviors is critical to devising effective HIV prevention strategies. In conjunction with a large clinical trial in Lusaka, Zambia, we surveyed postpartum women who had been tested for HIV but did not know their status before undergoing the questionnaire. Of 858 women for whom complete data were available, 248 (29%) were HIV infected. Women 22 years of age or older (adjusted odds ratio [AOR], 1.7; 95% confidence interval [CI], 1.1–2.5), women reporting ≥2 sexual partners in their lifetime (AOR, 1.8; 95% CI, 1.3–2.5), and women reporting a history of a sexually transmitted infection (AOR, 2.7; 95% CI, 1.7–4.3) were more likely to be HIV infected. Having had ≥2 lifetime sexual partners was a marker for perception of high personnel risk for HIV infection (AOR, 1.5; 95% CI, 1.1–2.1). However, there was no relationship between perceived risk of HIV infection and actual HIV status. In fact, 127 (52%) of 245 women who stated that they were at no or low risk for HIV infection were HIV infected. Living in an area of high HIV seroprevalence like Zambia seems to be the greatest risk factor for infection in unselected pregnant women. Before significant inroads can be made in decreasing the incidence of HIV infection among pregnant women, population-based strategies that involve men must be implemented. PMID:14707794

Summary Despite significant reductions in morbidity and mortality secondary to availability of effective combination antiretroviral therapy (cART), human immunodeficiency virus (HIV) infection still accounts for 1.5 million deaths annually. The majority of deaths occur in sub-Saharan Africa where rates of opportunistic co-infections are disproportionately high. In this review, we discuss the immunopathogenesis of five common infections that cause significant morbidity in HIV-infected patients globally. These include co-infection with Mycobacterium tuberculosis, Cryptococcus neoformans, hepatitis B virus (HBV), hepatitis C virus (HCV), and Plasmodium falciparum. Specifically, we review the natural history of each co-infection in the setting of HIV, the specific immune defects induced by HIV, the effects of cART on the immune response to the co-infection, the pathogenesis of immune restoration disease (IRD) associated with each infection, and advances in the areas of prevention of each co-infection via vaccination. Finally, we discuss the opportunities and gaps for future research. PMID:23772618

). Physical IPV alone was not associated with risk of HIV infection. Women's personal sexual risk behaviors were not associated with HIV infection. Among married Indian women, physical violence combined with sexual violence from husbands was associated with an increased prevalence of HIV infection. Prevention of IPV may augment efforts to reduce the spread of HIV/AIDS.

Schistosomiasis affects 218 million people worldwide, with most infections in Africa. Prevalence studies suggest that people with chronic schistosomiasis may have higher risk of HIV-1 acquisition and impaired ability to control HIV-1 replication once infected. We hypothesized that: (1) pre-existing schistosome infection may increase the odds of HIV-1 acquisition and that the effects may differ between men and women, and (2) individuals with active schistosome infection at the time of HIV-1 acquisition may have impaired immune control of HIV-1, resulting in higher HIV-1 viral loads at HIV-1 seroconversion. We conducted a nested case-control study within a large population-based survey of HIV-1 transmission in Tanzania. A population of adults from seven villages was tested for HIV in 2007, 2010, and 2013 and dried blood spots were archived for future studies with participants' consent. Approximately 40% of this population has Schistosoma mansoni infection, and 2% has S. haematobium. We tested for schistosome antigens in the pre- and post-HIV-1-seroconversion blood spots of people who acquired HIV-1. We also tested blood spots of matched controls who did not acquire HIV-1 and calculated the odds that a person with schistosomiasis would become HIV-1-infected compared to these matched controls. Analysis was stratified by gender. We compared 73 HIV-1 seroconverters with 265 controls. Women with schistosome infections had a higher odds of HIV-1 acquisition than those without (adjusted OR = 2.8 [1.2-6.6], p = 0.019). Schistosome-infected men did not have an increased odds of HIV-1 acquisition (adjusted OR = 0.7 [0.3-1.8], p = 0.42). We additionally compared HIV-1 RNA levels in the post-seroconversion blood spots in HIV-1 seroconverters with schistosomiasis versus those without who became HIV-infected in 2010, before antiretroviral therapy was widely available in the region. The median whole blood HIV-1 RNA level in the 15 HIV-1 seroconverters with schistosome infection was

 There is a paucity of data regarding the burden of Bordetella pertussis in African women and young infants, and particularly the impact of maternal human immunodeficiency virus (HIV) infection thereon. We performed a retrospective analysis of respiratory illness samples from longitudinal cohorts of HIV-uninfected and HIV-infected women and their infants to evaluate the burden of pertussis illness in a black-African community.  The women were followed up for respiratory illness from midpregnancy and together with their infants until 24 weeks postpartum. Respiratory samples obtained at the time of illness visits were tested for B. pertussis by polymerase chain reaction (PCR).  The study included 194 HIV-infected and 1060 HIV-uninfected women, and 188 and 1028 infant offspring, respectively. There were 7 PCR-confirmed pertussis cases in the HIV-exposed infants and 30 in HIV-unexposed infants (7.4 vs 5.5 episodes per 1000 infant-months; P = .47), at a mean age of 70.9 days. All infant pertussis cases had a history of cough (mean duration, 6.3 days). Six of 17 (35.3%) pertussis-confirmed cases in infants <2 months of age were admitted to hospital within 21 days of B. pertussis detection, whereas none of the 20 cases ≥2 months of age required hospitalization. Ten PCR-positive pertussis-associated illnesses were detected in HIV-infected women compared with 32 in the HIV-uninfected women (6.8 vs 3.9 episodes per 1000 person-months; P = .12).  Bordetella pertussis identification was common among young infants with respiratory illness, most of whom were too young to be fully protected through direct vaccination. Vaccination of pregnant women might be a valuable strategy in a setting such us ours to prevent B. pertussis-associated illness in women and their young infants. © The Author 2016.

Aims This study assessed the effectiveness of HERMITAGE (HIV’s Evolution in Russia - Mitigating Infection Transmission and Alcoholism in a Growing Epidemic), an adapted secondary HIV prevention intervention, compared with an attention control condition in decreasing sexually transmitted infections (STIs) and sex and drug risk behaviors among Russian HIV-infected heavy drinkers. Design We conducted a single-blinded, two-armed, randomized controlled trial with 12-month follow-up. Setting The study was conducted in St. Petersburg, Russia. Participants were recruited from four HIV and addiction clinical sites. The intervention was conducted at Botkin Infectious Disease Hospital. Participants HIV-infected persons with past 6-month risky sex and heavy alcohol consumption (n=700) were randomized to the HERMITAGE intervention (n=350) or an attention control condition (n=350). Intervention A Healthy Relationships Intervention stressing disclosure of HIV serostatus and condom use, adapted for a Russian clinical setting with two individual sessions and three small group sessions. Measurements The primary outcome was incident STI by laboratory test at 12-month follow-up. Secondary outcomes included change in unprotected sex and several alcohol and injection drug use (IDU) variables. Findings Participants had the following baseline characteristics: 59% male, mean age 30, 60% past year IDU, 15.4% prevalent STI and mean CD4 cell count 413/μl. Assessment occurred among 75% and 71% of participants at 6 and 12-months, respectively. STIs occurred in 20 subjects (8%) in the intervention group and 28 subjects (12%) in the control group at 12-month follow-up; logistic regression analyses found no significant difference between groups (adjusted odds ratio 0.69; 95% CI: 0.36-1.30; P=0.25). Both groups decreased unsafe behaviors, although no significant differences between groups were found. Conclusions The HERMITAGE HIV risk reduction intervention does not appear to reduce sexually

ADHERENCE TO ANTIRETROVIRAL THERAPY AMONG HIV-INFECTED ADULTS IN THE UNITED STATES

2015-01-01

National estimates of antiretroviral therapy (ART) adherence and adherence support services utilization are needed to inform efforts to improve the health of HIV-infected persons in the United States. In a nationally representative sample of HIV-infected adults receiving medical care, 86% self-reported taking all ART doses in the past 72 hours. Overall, 20% reported using adherence support services and 2% reported an unmet need for services. If all nonadherent persons not receiving adherence support and all persons with a self-perceived unmet need for adherence support accessed services, resources to support ~42,673 additional persons would be needed. Factors associated with lower adherence included younger age, female gender, depression, stimulant use, binge alcohol use, greater than once-daily dosing, longer time since HIV diagnosis, and patient beliefs. Predictors of adherence are multifactorial so multiple targeted strategies to improve adherence are warranted. Providing adherence support services to all those in need may require additional resources. PMID:25490733

Aging, inflammation, and HIV infection.

PubMed

Aberg, Judith A

2012-01-01

Prolonged survival in HIV infection is accompanied by an increased frequency of non-HIV-related comorbidities. A number of age-related comorbidities occur earlier in HIV-infected patients than in individuals without HIV infection. This "accelerated aging" appears to be largely related to chronic inflammation, chronic immune activation, and immunosenescence in HIV infection. Levels of markers of inflammation and coagulopathy are elevated in HIV-infected patients, and elevations in markers such as high-sensitivity C-reactive protein, D-dimer, and interleukin 6 (IL-6) have been associated with increased risk for cardiovascular disease, opportunistic conditions, or all-cause mortality. In both HIV infection and aging, immunosenescence is marked by an increased proportion of CD28-, CD57+ memory CD8+ T cells with reduced capacity to produce interleukin 2 (IL-2), increased production of IL-6, resistance to apoptosis, and shortened telomeres. A number of AIDS Clinical Trials Group studies are under way to examine treatment aimed at reducing chronic inflammation and immune activation in HIV infection. This article summarizes a presentation by Judith A. Aberg, MD, at the IAS-USA live continuing medical education course held in New York City in October 2011.

HIV antibodies for treatment of HIV infection

PubMed Central

Margolis, David M.; Koup, Richard A.; Ferrari, Guido

2016-01-01

Summary The bar is high to improve on current combination antiretroviral therapy (ART), now highly effective, safe, and simple. However antibodies that bind the HIV envelope are able to uniquely target the virus as it seeks to enter new target cells, or as it is expressed from previously infected cells. Further, the use of antibodies against HIV as a therapeutic may offer advantages. Antibodies can have long half-lives, and are being considered as partners for long-acting antiretrovirals for use in therapy or prevention of HIV infection. Early studies in animal models and in clinical trials suggest that such antibodies can have antiviral activity but, as with small molecule antiretrovirals, the issues of viral escape and resistance will have to be addressed. Most promising, however, are the unique properties of anti-HIV antibodies: the potential ability to opsonize viral particles, to direct antibody-dependent cellular cytotoxicity (ADCC) against actively infected cells, and ultimately the ability to direct the clearance of HIV-infected cells by effector cells of the immune system. These distinctive activities suggest that HIV antibodies and their derivatives may play an important role in the next frontier of HIV therapeutics, the effort to develop treatments that could lead to an HIV cure.

Despite great improvements in prevention over the last years, much has to be done to reduce new human immunodeficiency virus (HIV) infections. Substantial evidence shows that the six-month period of recent HIV infection contributes disproportionately to HIV transmission. This study aims to investigate knowledge, normative beliefs, and attitudes of people who inject drugs (PWID) regarding recent HIV infection. People who inject drugs in Athens, Greece were recruited in the fifth round of a respondent- driven sampling program (ARISTOTLE). The participants were tested for HIV and answered a structured questionnaire, which also included items on knowledge, normative beliefs, and attitudes regarding recent infection to address needs of the social network-based Transmission Reduction Intervention Project. The multivariable analyses included logistic regression models, which produced odds ratios (OR) and 95% confidence intervals (CI). In total, 1,407 people (mean age: 36.3 ± 7.9 years old; males: 81.9%) took part in the fifth round of ARISTOTLE. Of these, 61.5% knew that HIV-infected people who are not on treatment are more likely to transmit HIV during the first six months of their infection and 58.4% reported that people in their network would react positively towards a recently HIV-infected person. People who inject drugs who were knowledgeable of recent HIV infection were more likely to disagree with statements such as that one should avoid all contact with a person recently infected by HIV (adjusted OR: 1.510, 95% CI: 1.090, 2.091) or more likely to agree with statements such as that an HIV+ person is much less likely to transmit HIV when h/she is on combination antiretroviral treatment (adjusted OR: 2.083, 95% CI: 1.231, 3.523). A considerable proportion of PWID in Athens, Greece, were aware of the high HIV transmission risk of recent HIV infection, although improvement is needed for some population segments.

The prevalence of HIV-infected people aged 50 years or older is increasing rapidly; the proportion will increase from 28% to 73% in 2030. In addition, HIV-infected individuals may be more vulnerable to age-related condition. There is growing evidence that the prevalence of comorbidities and other age-related conditions (geriatric syndromes, functional or neurocognitive/mental problems, polypharmacy, and social difficulties) is higher in the HIV-infected population than in their uninfected counterparts. However, despite the potential impact of this situation on health care, little information exists about the optimal clinical management of older HIV-infected people. Here we examine the age-related conditions in older HIV-infected persons and address clinical management according to author expertise and published literature. Our aim is to advance the debate about the most appropriate management of this population, including less well-studied aspects, such as frequency of screening for psychological/mental and social and functional capabilities.

Human Immunodeficiency Virus (HIV) infection leads to acquired immunodeficiency syndrome (AIDS) and major causes of morbidity and mortality of such patients are opportunistic infections caused by viral, bacterial, fungal and parasitic pathogens. To determine the magnitude of opportunistic and non-opportunistic intestinal parasitic infections among AIDS patients and HIV positive carrier individuals. Cross-sectional study was conducted among AIDS patients, HIV positive healthy carriers and HIV negative individuals in Jimma University Hospital, Mother Theresa Missionary Charity Centre, Medan Acts Projects and Mekdim HIV positive persons and AIDS orphans' national association from January to May, 2004. Convenient sampling technique was employed to identify the study subjects and hence a total of 160 subjects were included. A pre-tested structured questionnaire was used to collect socio-demographic data of the patients. Stool samples were examined by direct saline, iodine wet mount, formol-ether sedimentation concentration, oocyst concentration and modified Ziehl-Neelsen staining technique. Out of 160 persons enrolled in this study 100 (62.5%) (i.e. 65 male and 35 female) were infected with one or more intestinal parasites. The highest rate 36 (69.2%) of intestinal parasites were observed among HIV/AIDS patients, followed by HIV positive healthy carriers 35 (61.4%) of and HIV negative individuals (29 (56.9%). Isospora belli 2 (3.9%), Cryptosporidum parvum 8 (15.4%), Strongyloides stercoralis 6 (11.5%) and Blastocystis 2 (3.9%) were found only in HIV/AIDS groups I. belli, C. parvum, S. stercoralis and Blastocystis are the major opportunistic intestinal parasites observed in HIV/AIDS patients. Therefore, early detection and treatment of these parasites are important to improve the quality of life of HIV/AIDS patients with diarrhoea.

Background Sexually transmitted infections (STIs) including Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), Treponema pallidum (TP), and cytomegalovirus (CMV) may lead to adverse pregnancy and infant outcomes. The role of combined maternal STIs in HIV mother-to-child transmission (MTCT) was evaluated in mother-infant pairs from NICHD HPTN 040. Methodology Urine samples from HIV-infected pregnant women during labor were tested by polymerase chain reaction (PCR) for CT, NG, and CMV. Infant HIV infection was determined by serial HIV DNA PCR testing. Maternal syphilis was tested by VDRL and confirmatory treponemal antibodies. Results A total of 899 mother-infant pairs were evaluated. Over 30% had at least one of the following infections (TP, CT, NG, and/or CMV) detected at the time of delivery. High rates of TP (8.7%), CT (17.8%), NG (4%), and CMV (6.3%) were observed. HIV MTCT was 9.1% (n = 82 infants). HIV MTCT was 12.5%, 10.3%, 11.1%, and 26.3% among infants born to women with CT, TP, NG or CMV respectively. Forty-two percent of HIV-infected infants were born to women with at least one of these 4 infections. Women with these infections were nearly twice as likely to have an HIV-infected infant (aOR 1.9, 95% CI 1.1–3.0), particularly those with 2 STIs (aOR 3.4, 95% CI 1.5–7.7). Individually, maternal CMV (aOR 4.4 1.5–13.0) and infant congenital CMV (OR 4.1, 95% CI 2.2–7.8) but not other STIs (TP, CT, or NG) were associated with an increased risk of HIV MTCT. Conclusion HIV-infected pregnant women identified during labor are at high risk for STIs. Co-infection with STIs including CMV nearly doubles HIV MTCT risk. CMV infection appears to confer the largest risk of HIV MTCT. Trial registration NCT00099359. PMID:29304083

We sought to identify the socioeconomic impact on people living with HIV (PLWH) in Sudan. Focus group discussions were used to collect data and identify the most outstanding domains of HIV impact on PLWH and the survival mechanisms that may be common to a group of diverse HIV-infected persons (n = 30). The findings indicated that the most striking financial and social impacts were due to stigma associated with HIV in the conservative Sudanese society, which led to loss of work with all its consequences (e.g., children's education and health care expenses were affected). The socioeconomic impacts of HIV on infected populations are discussed, and suggestions for possible interventions to mitigate harmful impacts and stigma within the society, the workplace, and health care settings are highlighted. We concluded that HIV has intensified the existing problems of infected people, contributing to their vulnerability to poverty. Copyright © 2016 Association of Nurses in AIDS Care.

Kidney transplantation is now considered the treatment of choice for many human immunodeficiency virus (HIV)-infected patients with end-stage renal disease (ESRD). Graft survival rates using HIV-negative donors and carefully selected HIV-positive ESRD patients are similar to those observed in HIV-uninfected kidney transplant recipients. To address the relative shortfall in donated organs it has been proposed that organs from HIV-infected deceased donors might be allocated to HIV-infected patients on the transplant waiting list. Preliminary experience in South Africa reports promising short-term outcomes in a small number of HIV-infected recipients of kidney transplants from HIV-infected donors. We sought to replicate this experience in the UK by accepting kidney offers from HIV infected deceased donors for patients with HIV-infection on the kidney transplant waiting list. Here we report the UK's first cases of kidney transplantation between HIV-positive donors and recipients.

Background Sexually transmitted infections (STI) may directly increase the risk of HIV infection, or may indicate sexual practices that increase the risk of HIV infection. In persons with HIV they probably also increase the infectiousness of HIV, even in the context of treatment with antiretroviral drugs (ARV). Estimating STI in this group has proved problematic, and there are few longitudinal studies able to accurately measure incidence. Methods In 2010, we established a cohort of individuals from ten widely dispersed sexual health clinics that were already enrolled in the Australian HIV Observational Database (AHOD). We calculated retrospective diagnosis rates for four STI (chlamydia, gonorrhoea, infectious syphilis, anogenital warts) from 2005-2010, and prospective incidence rates from 2010-2011. Results At baseline (2010) , the patient characteristics (n=554) were similar to the rest of AHOD (n=1767), namely they were predominantly male, homosexual, middle-aged, and pre- treated with ARV. Overall, the incidence of any STI was 12.5/100 person years (py). There was a gradual increase in chlamydial infections , from 3.4/100 py (95% CI 1.9-5.7) in 2005 to 6.7/100py (95% CI 4.5-9.5) in 2011, with a substantial peak of 8.1/100py (95% CI 5.6-11.2) in 2010. The cases were distributed between rectal ( 61.9%), urethral (34%), and pharyngeal (6.3%) sites. Similarly, gonococcal infections increased, with a peak in 2010 of 4.7/100py (95% CI 5.6-11.2), (p value for trend=0.0099), distributed between rectal (63.9%), urethral (27.9%), and pharyngeal (14.8%) sites. Infectious syphilis showed several peaks, the largest in 2008 (5.3/100py , (95% CI 3.3-8.0), but the overall trend was not significant (p=0.113). Diagnoses of genital warts declined from 7.5/100py (95% CI 4.8-11.3) in 2005 (95% CI 4.8-11.3) to 2.4/100py (95% CI 1.1-4.5) in 2011 (p value for trend=0.0016). Conclusions The incidence of chlamydial and gonococcal infections in this cohort was higher than previous

To determine influence of age and HIV infection on influenza vaccine responses. Evaluate serologic response to seasonal trivalent influenza vaccine (TIV) as the immunologic outcome in HIV-infected (HIV) and age-matched HIV negative (HIV) adults. During 2013-2016, 151 virologically controlled HIV individuals on antiretroviral therapy and 164 HIV volunteers grouped by age as young (<40 years), middle aged (40-59 years) and old (≥60 years) were administered TIV and investigated for serum antibody response to vaccine antigens. At prevaccination (T0) titers were in seroprotective range in more than 90% of participants. Antibody titers increased in all participants postvaccination but frequency of classified vaccine responders to individual or all three vaccine antigens at 3-4 weeks was higher in HIV than HIV adults with the greatest differences manifesting in the young age group. Of the three vaccine strains in TIV, antibody responses at T2 were weakest against H3N2 with those to H1N1 and B antigens dominating. Among the age groups, the titers for H1N1 and B were lowest in old age, with evidence of an age-associated interaction in HIV persons with antibody to B antigen. Greater frequencies of vaccine nonresponders are seen in HIV young compared with HIV adults and the observed age-associated interaction for B antigen in HIV persons are supportive of the concept of premature immune senescence in controlled HIV infection. High-potency influenza vaccination recommended for healthy aging could be considered for HIV adults of all ages.

Educational software for simulating risk of HIV infection

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.

HIV Infection and Bone Abnormalities.

More than 36 million people are living with human immunodeficiency virus (HIV) infection worldwide and 50% of them have access to antiretroviral therapy (ART). While recent advances in HIV therapy have reduced the viral load, restored CD4 T cell counts and decreased opportunistic infections, several bone-related abnormalities such as low bone mineral density (BMD), osteoporosis, osteopenia, osteomalacia and fractures have emerged in HIV-infected individuals. Of all classes of antiretroviral agents, HIV protease inhibitors used in ART combination showed a higher frequency of osteopenia, osteoporosis and low BMD in HIV-infected patients. Although the mechanisms of HIV and/or ART associated bone abnormalities are not known, it is believed that the damage is caused by a complex interaction of T lymphocytes with osteoclasts and osteoblasts, likely influenced by both HIV and ART. In addition, infection of osteoclasts and bone marrow stromal cells by HIV, including HIV Gp120 induced apoptosis of osteoblasts and release of proinflammatory cytokines have been implicated in impairment of bone development and maturation. Several of the newer antiretroviral agents currently used in ART combination, including the widely used tenofovir in different formulations show relative adverse effects on BMD. In this context, switching the HIV-regimen from tenofovir disoproxil fumarate (TDF) to tenofovir alafenamide (TAF) showed improvement in BMD of HIV-infected patients. In addition, inclusion of integrase inhibitor in ART combination is associated with improved BMD in patients. Furthermore, supplementation of vitamin D and calcium with the initiation of ART may mitigate bone loss. Therefore, levels of vitamin D and calcium should be part of the evaluation of HIV-infected patients.

Background. Parainfluenza virus (PIV) is a common cause of acute respiratory tract infections, but little is known about PIV infection in children and adults in Africa, especially in settings where human immunodeficiency virus (HIV) prevalence is high. Methods. We conducted active, prospective sentinel surveillance for children and adults hospitalized with severe acute respiratory illness (SARI) from 2009 to 2014 in South Africa. We enrolled controls (outpatients without febrile or respiratory illness) to calculate the attributable fraction for PIV infection. Respiratory specimens were tested by multiplex real-time reverse-transcription polymerase chain reaction assay for parainfluenza types 1, 2, and 3. Results. Of 18 282 SARI cases enrolled, 1188 (6.5%) tested positive for any PIV type: 230 (19.4%) were type 1; 168 (14.1%) were type 2; 762 (64.1%) were type 3; and 28 (2.4%) had coinfection with 2 PIV types. After adjusting for age, HIV serostatus, and respiratory viral coinfection, the attributable fraction for PIV was 65.6% (95% CI [confidence interval], 47.1–77.7); PIV contributed to SARI among HIV-infected and -uninfected children <5 years of age and among individuals infected with PIV types 1 and 3. The observed overall incidence of PIV-associated SARI was 38 (95% CI, 36–39) cases per 100 000 population and was highest in children <1 year of age (925 [95% CI, 864–989] cases per 100 000 population). Compared with persons without HIV, persons with HIV had an increased relative risk of PIV hospitalization (9.4; 95% CI, 8.5–10.3). Conclusions. Parainfluenza virus causes substantial severe respiratory disease in South Africa among children <5 years of age, especially those that are infected with HIV. PMID:26566534

Objective To determine if significant differences exist in substance use among people living with HIV/AIDS (PLWHA) before and after establishing their HIV infection status. Method The study participants are HIV positive clients of a community based HIV/AIDS outreach facility located in Montgomery, Alabama. The questionnaire includes demographics, substance use and risky sexual behaviors pertaining to HIV transmission. Each participant completed an anonymous questionnaire. A total of 341 questionnaires were distributed and 326 were fully completed and returned, representing a response rate of 96%. Results Findings revealed a statistically significant difference in alcohol consumption before sex among PLWHA before and after establishing their HIV infection status (p = .001). No significant differences were observed among participants who reported as having used drugs intravenously (p = .89), and among those sharing the same syringe/needle with another person (p = .87) before and after establishing their HIV infection status. Conclusion There is continued substance use and alcohol consumption before sex among PLWHA after establishing their HIV status despite clear evidence of such risky behaviors that could lead to an increase in exposure to HIV.

Background The US Centers for Disease Control and Prevention (CDC) recently add the advice of one-time testing of HCV infection in persons born during 1945–1965. Moreover, the US Preventive Services Task Force (USPSTF) newly recommended one-time HIV testing for persons aged 15–65. Herein, we evaluate the potential impact of these recommendations in a reference medical area of Spain. Methods All assays results entries for HCV and HIV serological markers ordered at a reference lab from primary care and specialized physicians between 2008 and 2012 were recorded in a medical area which covers 501,526 citizens in Northern Spain. The year of birth were also documented. Results A total of 108,159 anti-HCV-Ab results were generated during the study period. The global rate of anti-HCV-Ab+ was 7.7% (95% CI: 7.6%–7.9%), being more prevalent in men than women (8.6% vs. 4.5%). By year of birth, the highest prevalence was found in persons born between 1955 and 1970. HCV genotype 1 was the most prevalent (59.7%) followed by genotype 3 (22.7%). Regard HIV infection, among 65,279 anti-HIV results generated the prevalence of anti-HIV+ was 1.1% (95% CI: 1.0%–1.2%), being more frequent in men (2% vs 0.5%). The years of birth with highest rates of HIV infection exactly match with those for HCV infection. Conclusions The highest rates of HCV and HIV infections are found between 1960 and 1965. Different historical and social circumstances such as the huge intravenous drug use epidemic in the eighties in Spain, might explain it. Therefore, each country needs to determine its own HCV and HIV seroprevalences by year of birth to establish the proper recommendations for the screening of both infections. PMID:25436642

Objectives To examine changes in use of prescription opioids for the management of chronic non-cancer pain in HIV-infected patients and to identify patient characteristics associated with long-term use. Methods Long-term prescription opioid use (i.e. 120+ days supply or 10+ prescriptions during a year) was assessed between 1997 and 2005 among 6,939 HIV-infected Kaiser Permanente members and HIV-uninfected persons in the general health plan memberships. Results In 2005, 8% of HIV+ individuals had prevalent long-term opioid use, more than double the prevalence among HIV-uninfected individuals. However, the large increases in use from 1997 to 2005 in the general population were not observed for HIV-infected individuals. The strongest associations with prevalent use among HIV-infected individuals were female gender with a prevalence ratio [PR] of 1.8 (95% CI=1.3, 2.5); Charlson comorbidity score of 2 or more (compared with a score of 0) with a PR of 1.9 (95% CI=1.4, 2.8); injection drug use history with a PR of 1.8 (95% CI=1.3, 2.6); substance use disorders with a PR of 1.8 (95% CI=1.3, 2.5). CD4, HIV RNA, and AIDS diagnoses were associated with prevalent opioid use early in the antiretroviral therapy era (1997), but not in 2005. Conclusions Long-term opioid use for chronic pain has remained stable over time for HIV patients, while use increased in the general population. The prevalence of prescribed opioids in HIV patients was highest for certain subgroups, including women, and those with a comorbidity and substance abuse history. PMID:21677568

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

People infected by Human Immunodeficiency Virus (HIV) are susceptible to develop severe bacterial infections. We set out to determine the frequency and the sensitivity to antibiotics of enterobaceriaceae isolated from urine and feces of HIV-infected persons. Urine and feces samples were collected from HIV-infected patients of the Centre de Traitement Ambulatoire de Kabinda (CTA/Kabinda, Kinshasa) and analyzed at the Reference National Laboratory for HIV/AIDS and Sexually Transmitted Infections. The isolated enterobacteriaceae strains were identified by conventional microbiological methods. Antibiotic sensitivity pattern was carried out by disc diffusion method. THE FOLLOWING BACTERIA PATHOGENS WERE ISOLATED: Escherichia coli, Klebsiella, Enterobacter, Proteus, and Providencia. Most species were sensitive to cefotaxim, ceftriaxon, and gentamicin and resistant to chloramphenicol, cotrimoxazole, tetracycline, and norfloxacin. The results of the present study show that the most frequently bacteria isolated were Esherichia coli and cefotaxim, ceftriaxon, and gentamicin were the most active antibiotics.

Although case management has been advocated as a method for improving the care of chronically ill persons, its effectiveness is poorly understood. To assess the effect of case managers on unmet need for supportive services and utilization of medical care and medications among HIV-infected persons. Baseline and follow-up interview of a national probability sample. Inpatient and outpatient medical facilities in the United States. 2437 HIV-infected adults representing 217 081 patients receiving medical care. Outcomes measured at follow-up were unmet need for supportive services, medical care utilization (ambulatory visits, emergency department visits, and hospitalizations), and use of HIV medication (receipt of antiretroviral therapy and prophylaxis against Pneumocystis carinii pneumonia and toxoplasmosis). At baseline, 56.5% of the sample had contact with a case manager in the previous 6 months. In multiple logistic regression analyses that adjusted for potential confounders, contact with a case manager at baseline was associated with decreased unmet need for income assistance (odds ratio [OR], 0.57 [95% CI, 0.36 to 0.91]), health insurance (OR, 0.54 [CI, 0.33 to 0.89]), home health care (OR, 0.29 [CI, 0.15 to 0.56]), and emotional counseling (OR, 0.62 [CI, 0.41 to 0.94]) at follow-up. Contact with case managers was not significantly associated with utilization of ambulatory care (OR, 0.77 [CI, 0.57 to 1.04]), hospitalization (OR, 1.13 [CI, 0.84 to 1.54]), or emergency department visits (OR, 1.30 [CI, 0.97 to 1.73]) but was associated with higher utilization of two-drug (OR, 1.58 [CI, 1.23 to 2.03]) and three-drug (OR, 1.34 [CI, 1.00 to 1.80]) antiretroviral regimens and of treatment with protease inhibitors or non-nucleoside reverse transcriptase inhibitors (OR, 1.29 [CI, 1.02 to 1.64]) at follow-up. Case management appears to be associated with fewer unmet needs and higher use of HIV medications in patients receiving HIV treatment.

There are hardly any data about the incidence, risk factors and outcomes of ICU-associated A.baumannii colonisation/infection in HIV-infected and uninfected persons from resource-poor settings like Africa. We reviewed the case records of patients with A.baumannii colonisation/infection admitted into the adult respiratory and surgical ICUs in Cape Town, South Africa, from January 1 to December 31 2008. In contrast to colonisation, infection was defined as isolation of A.baumannii from any biological site in conjunction with a compatible clinical picture warranting treatment with antibiotics effective against A.baumannii. The incidence of A.baumannii colonisation/infection in 268 patients was 15 per 100 person-years, with an in-ICU mortality of 26.5 per 100 person-years. The average length of stay in ICU was 15 days (range 1-150). A.baumannii was most commonly isolated from the respiratory tract followed by the bloodstream. Independent predictors of mortality included older age (p = 0.02), low CD4 count if HIV-infected (p = 0.038), surgical intervention (p = 0.047), co-morbid Gram-negative sepsis (p = 0.01), high APACHE-II score (p = 0.001), multi-organ dysfunction syndrome (p = 0.012), and a positive blood culture for A.baumannii (p = 0.017). Of 21 A.baumannii colonised/infected HIV-positive persons those with clinical AIDS (CD4<200 cells/mm(3)) had significantly higher in-ICU mortality and were more likely to have a positive blood culture. Conclusion In this resource-poor setting A.baumannii infection in critically ill patients is common and associated with high mortality. HIV co-infected patients with advanced immunosuppression are at higher risk of death.

Subclinical kidney disease is associated with developing hypertension in the general population, but data are lacking among HIV-infected persons. We examined associations of kidney function and injury with incident hypertension in 823 HIV-infected and 267 HIV-uninfected women in the Women’s Interagency HIV Study, a multicenter, prospective cohort of HIV-infected and uninfected women in the United States. Baseline kidney biomarkers included estimated glomerular filtration rate using cystatin C (eGFR), urine albumin-to-creatinine ratio (ACR), and seven urine biomarkers of tubular injury: alpha-1-microglobulin, interleukin-18 (IL-18), kidney injury molecule-1, neutrophil gelatinase-associated lipocalin, liver fatty acid binding protein, N-acetyl-beta-D-glucosaminidase (NAG), and alpha1-acid-glycoprotein (AAG). We used multivariable Poisson regression to evaluate associations of kidney biomarkers with incident hypertension, defined as two consecutive visits of anti-hypertensive medication use. Over a median follow-up of 9.6 years, 288 HIV-infected women (35%) developed hypertension. Among the HIV-infected women, higher ACR was independently associated with incident hypertension (RR=1.13 per ACR doubling, 95%CI: 1.07, 1.20), as was lower eGFR (RR=1.10 per 10 ml/min/1.73m2 lower eGFR, CI: 1.04, 1.17). No tubular injury and dysfunction biomarkers were independently associated with incident hypertension in HIV-infected women. In contrast, among the HIV-uninfected women, ACR was not associated with incident hypertension, whereas higher IL-18, AAG and NAG were significantly associated with incident hypertension. These findings suggest that early glomerular injury and kidney dysfunction may be involved in the pathogenesis of hypertension in HIV-infected persons. The associations of the tubular markers with hypertension in HIV-uninfected women should be validated in other studies. PMID:27993956

Numerators were numbers of records of multiple-cause mortality data from the national vital statistics system with an ICD-10 code for the disease of interest (any mention, not necessarily the underlying cause), divided into those 1) with and 2) without an additional code for HIV infection. Denominators were 1) estimates of persons living with diagnosed HIV infection from national HIV surveillance system data and 2) general population estimates from the US Census Bureau. We compared age-adjusted rates overall (unstratified by sex, race/ethnicity, or region of residence) and stratified by demographic group. Overall, compared with the general population, persons diagnosed with HIV infection had higher age-adjusted rates of death reported with hepatitis B (rate ratio [RR]=42.6; 95% CI: 34.7-50.7), hepatitis C (RR=19.4; 95% CI: 18.1-20.8), liver disease excluding hepatitis B or C (RR=2.1; 95% CI: 1.8-2.3), kidney disease (RR=2.4; 95% CI: 2.2-2.6), and cardiomyopathy (RR=1.9; 95% CI: 1.6-2.3), but lower rates of death reported with ischemic heart disease (RR=0.6; 95% CI: 0.6-0.7) and heart failure (RR=0.8; 95% CI: 0.6-0.9). However, the differences in rates of death reported with the heart diseases were insignificant in some demographic groups. Persons with HIV infection have a higher risk of death with liver and kidney diseases reported as causes than the general population.

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

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

Factors and facts in Hungarian HIV/AIDS epidemic, 1985-2000.

In Hungary among others there were some special factors, which shaped the outcome of HIV/AIDS epidemic. (1) In the early period of pandemic the "iron curtain" delayed and limited the importation of HIV to Hungary. (2) In 1985, at the time of detection of first HIV infected persons the etiological diagnostic tools were already commercially available and laboratory facilities have been created immediately for HIV antibody tests in networks of blood banks, public health and venereological services. (3) Laboratory facilities together with introduced health regulations resulted in (a) elimination of possibility of nosocomial HIV transmission by blood, blood products and organ transplantation; (b) efficient case finding and contact tracing in population groups potentially playing a significant role in spreading of infection; (c) opportunities for voluntary HIV testing free of charge. (4) Broad scale education and information activities have been developed from the beginning by governmental and non-governmental organizations alike. (5) Parenteral drug abuse did not play a role in spreading of HIV, so far. The above factors resulted in a slowly developing moderate epidemic. The facts are as follows. By the end of 2000 altogether 879 HIV positive (666 male, 100 female and 113 anonymous) persons have been notified, 377 (344 male and 33 female) of whom showed already the characteristic features of AIDS and 229 died. 29% of registered HIV positive persons have been foreigners originating from 56 countries. The cumulative incidence rate of AIDS was 38 per million population. 73% of Hungarian HIV positive persons and 72% of patients with AIDS belonged to transmission group of men having sex with men. The age of HIV positive persons at the time of detection was between 20 and 49 years in 81% and 72% of them resided in or around Budapest.

To determine whether the total lymphocyte count (TLC) accurately predicts a low absolute CD4+ T-cell count and CD4+ percentage in persons infected with human immunodeficiency virus (HIV). Retrospective analysis of data collected in the US Air Force HIV Natural History Study. Military medical center that performs annual medical evaluation of all HIV-infected US Air Force personnel. A total of 828 consecutive patients with no prior history of zidovudine use, evaluated from January 1985 through July 1991. For patients with multiple observations over time, a single data point within each 6-month interval was included in the analysis (N = 2866). The sensitivity, specificity, and likelihood ratio (LR) of the TLC, in the range of 1.00 x 10(9)/L to 2.00 x 10(9)/L, in predicting an absolute CD4+ T-cell count less than 0.20 x 10(9)/L or a CD4+ percentage less than 20% were calculated. In addition, the LR and pretest probability of significant immunosuppression were used to calculate posttest probabilities of a low CD4+ count for a given TLC value. The LR of the TLC in predicting an absolute CD4+ count < 0.20 x 10(9)/L increased from 2.4 (95% confidence interval, 2.2 to 2.5) for all TLCs less than 2.00 x 10(9)/L, to 33.2 (95% confidence interval, 24.1 to 45.7) for all TLCs less than 1.00 x 10(9)/L. The specificity for this prediction increased from 57% to 97% over this range. The LR also increased from 1.4 (95% confidence interval, 1.3 to 1.6) for all TLCs less than 2.00 x 10(9)/L to 9.7 (95% confidence interval, 7.1 to 13.1) for all TLCs less than 1.00 x 10(9)/L in predicting a CD4+ percentage less than 20%. The TLC, between 1.00 x 10(9)/L and 2.00 x 10(9)/L, appears to be a useful predictor of significant immunosuppression as measured by a CD4+ T-cell count less than 0.20 x 10(9)/L in HIV-infected persons. The LR for a given TLC value and the pretest probability of immunosuppression can be used to determine the posttest probability of significant immunosuppression in

Antiretroviral therapy during the earliest stage of acute HIV infection (Fiebig I) might minimize establishment of a latent HIV reservoir and thereby facilitate viremic control after analytical treatment interruption. We show that 8 participants, who initiated treatment during Fiebig I and were treated for a median of 2.8 years, all experienced rapid viral load rebound following analytical treatment interruption, indicating that additional strategies are required to control or eradicate HIV.

Abstract Successful treatment of HIV infection requires regular clinical follow-up. A previously published risk-prediction tool (RPT) utilizing data from the electronic health record (EHR) including medication adherence, previous appointment attendance, substance abuse, recent CD4+ count, prior antiretroviral therapy (ART) exposure, prior treatment failure, and recent HIV-1 viral load (VL) has been shown to predict virologic failure at 1 year. If this same tool could be used to predict the more immediate event of appointment attendance, high-risk patients could be identified and interventions could be targeted to improve this outcome. We conducted an observational cohort study at the Vanderbilt Comprehensive Care Clinic from August 2013 through March 2014. Patients with routine medical appointments and most recent HIV-1 VL >200 copies/mL were included. Risk scores for a modified RPT were calculated based on data from the EHR. Odds ratios (OR) for missing the next appointment were estimated using multivariable logistic regression. Among 510 persons included, median age was 39 years, 74% were male, 55% were black, median CD4+ count was 327 cells/mm3 [Interquartile Range (IQR): 142–560], and median HIV-1 VL was 21,818 copies/mL (IQR: 2,030–69,597). Medium [OR 3.95, 95% confidence interval (CI) 2.08–7.50, p-value<0.01] and high (OR 9.55, 95% CI 4.31–21.16, p-value<0.01) vs. low RPT risk scores were independently associated with missing the next appointment. RPT scores, constructed using readily available data, allow for risk-stratification of HIV medical appointment non-attendance and could support targeting limited resources to improve appointment adherence in groups most at-risk of poor HIV outcomes.

HIV infection results in a decrease in circulating CD4+ T-cell and naive T-cell numbers. If such losses were associated with an erosion of T-cell receptor (TCR) repertoire diversity in the peripheral T-cell pool, this might exacerbate the state of persistent immunodeficiency. Existing methods for the analysis of the TCR repertoire have demonstrated skewed distributions of TCR genes in HIV-infected subjects but cannot directly measure TCR diversity. Here we used AmpliCot, a quantitative assay based on DNA hybridization kinetics, to measure TCR diversity in a cross-sectional comparison of 19 HIV-infected persons to 18 HIV-uninfected controls. HIV-infected persons had a 10-fold decrease in total TCR repertoire diversity in 1.5 mL of blood compared with uninfected controls, with decreased diversity correlating most closely with a lower CD4+ T-cell percentage. Nonetheless, the TCR repertoire diversity of sort-purified T-cell subpopulations in HIV-infected and HIV-uninfected subjects was comparable. These observations suggest that the TCR repertoire diversity changes in whole blood during HIV disease progression are primarily the result of changes in the number and proportion of T-cell subpopulations and that most HIV-infected persons may retain a sufficiently diverse TCR repertoire to permit immune reconstitution with antiretroviral therapy alone, without thymopoiesis.

In this study, we assessed the adverse reactions to influenza vaccination in HIV-infected individuals. From November 2006 to January 2007, a total of 203 HIV-infected persons were recruited. Demographic data were collected. Subjects were evaluated 48 h and 15 days after vaccination for symptoms and significant health events as possible side effects. Participants were instructed to measure their temperature in the morning and evening for 2 days post-immunization and to assess injection site and systemic adverse reactions. 80.3% of the subjects were male. The mean age of the subjects was 36.9 +/- 7.9 years. Local and systemic reactions were reported by 61 (30%) and 62 (30.5%) persons, respectively. The most common adverse reactions to the influenza vaccine included skin redness (37 cases), induration (32 cases), and pain (55 cases) as local reactions, and fever (22 cases), myalgia (46 cases), headache (12 cases) and weakness (35 cases) as general reactions. 1.4 % of the subjects had fever over 38.5 degrees C. There were significant associations between myalgia and flushing with CD4 counts (P<0.05). We found no relationship between adverse reactions and sex, history of smoking, allergy, alcohol, and drug usage, stage of HIV infection, anti-retroviral therapies, anti-TB medication and previous vaccination. We concluded that inactivated influenza vaccine administered in HIV-infected adults did not result in potential adverse events in this study population.

Purpose HIV infection has been implicated in dysregulation of the autonomic nervous system. Method Cross-sectional study examining the relationship between the presence of persistent detectable HIV viral load with autonomic function, measured by heart rate variability (HRV). Non-virologic suppression (NVS) was defined as having a detectable viral load for at least 3 months prior to autonomic function testing. HRV was measured during the following 4 maneuvers: resting and paced respirations and sustained handgrip and tilt. Inferences on parasympathetic and sympathetic modulations were determined by analyzing time and frequency domains of HRV. Results 57 participants were enrolled in 3 groups: 22 were HIV-infected participants with HIV virologic suppression (VS; undetectable HIV viral load), 9 were HIV-infected participants who had NVS, and 26 were HIV seronegative controls. There were lower time domain parameters in the HIV-infected group as a whole compared to controls. There were no significant differences in time domain parameters among HIV-infected participants. There were no differences in frequency domain parameters during any of the maneuvers between controls and all HIV-infected participants, nor between the NVS and VS groups. Conclusion There were differences in autonomic function between HIV-infected individuals and HIV seronegative controls, but not between the NVS and VS groups. PMID:21684854

The Burden of Neglected HIV-2 and HTLV-1 Infections in Spain.

HIV-2 and HTLV-1 infections are globally less frequent than those produced by HIV-1, the classical AIDS agent. In Spain and up to the end of 2014, a total of 310 cases of HIV-2, 274 of HTLV-1, and 776 of HTLV-2 infections had been reported. No cases of HTLV-3 or HTLV-4 infections have been identified so far in Spain. Most persons infected with HIV-2 or HTLV-1 acknowledge epidemiological risk factors for contagion, such as originating from or living in endemic regions and/or having had sexual partners from those areas. However, risk factors could not be recognized in up to 20-25% of carriers in Spain. Thus, it seems worth keeping a high level of clinical suspicion in order to identify earlier these neglected human retroviral infections, since diagnostic procedures and antiviral treatment are specific for each of these agents. In this article we summarize the major contributions reported at the meeting of the Spanish Group for HIV-2/HTLV held in Madrid in December 2014.

Tuberculosis (TB) remains the leading cause of death among human immunodeficiency virus (HIV) infected persons. The prevalence of infection with Mycobacterium tuberculosis and non-tuberculous mycobacteria (NTM) in HIV-infected patients in China is unknown. To estimate the prevalence of M. tuberculosis and NTM in HIV-infected patients in Guangxi Province, determine their drug resistance profiles, and evaluate the genotype patterns of M. tuberculosis strains. Samples were collected from two HIV designated hospitals in Guangxi Province between 2005 and 2008. HIV-infected patients who were culture-positive for mycobacteria were included. Drug susceptibility testing was performed for mycobacterial isolates. NTM species was identified by sequencing, and M. tuberculosis isolates were genotyped using the variable number of tandem repeats method. M. tuberculosis and NTM were identified in respectively 117 (53%) and 102 (47%) HIV-infected patients. Drug resistance was found in 27% and multi-drug-resistant TB (MDR-TB) in 11% of the patients with TB. Previous treatment for TB was significantly associated with MDR-TB. Twenty (17%) TB patients belonged to eight VNTR-defined clusters. The high frequency of NTM among HIV-infected patients raises concerns about accurate species identification before the determination of appropriate treatment. The potential for TB transmission exists among HIV-infected patients. Intensified screening and effective treatment of TB-HIV co-infected patients is urgently needed.

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

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

Increased HIV transmission in persons who inject drugs (PWIDs) has led to subepidemics and outbreaks in several countries in Europe, including Bulgaria. In this study in Bulgaria, we investigate the origin and spatiotemporal evolutionary history of HIV-1 infections in PWIDs and the distribution of antiretroviral resistance mutations and hepatitis co-infections in these populations. We analyzed HIV-1 polymerase sequences available from 117 of 359 PWIDs diagnosed with HIV/AIDS from 1999 to 2011. Of these, 50 (42.7%) were classified as CRF02_AG, 41 (35.0%) CRF01_AE, 12 (10.3%) URFs, ten (8.5%) subtype B, two (1.7%) subtype F1 and two (1.7%) CRF14_BG. Most recent common ancestor dating suggests that CRF01_AE was likely first introduced from Southeast Asia into persons reporting heterosexual infection in Bulgaria in 1992 and spread subsequently to PWIDs in the capital city of Sofia around 2003. Conversely, CRF02_AG in Bulgaria was likely first introduced into PWID from Germany in 2000 and later entered heterosexual populations around 2009. The overall prevalence of resistance mutations was 6.8% (8/117), of which 5.1% (5/117) was observed in patients on antiretroviral therapy and 1.7% (2/117) was from transmitted drug resistance mutations in drug-naïve individuals. 189/204 (92.6%) PWIDs were also co-infected with hepatitis C (HCV) and 31/183 (16.9%) were co-infected with hepatitis B (HBV). Our study provides valuable molecular epidemiological information on the introduction and distribution of the main HIV-1 subtypes, resistance mutations and hepatitis co-infections among PWIDs with HIV-1 in Bulgaria which can be used to target prevention efforts.

Background Cardiovascular disease is increased among HIV-infected patients, but little is known regarding ischemic stroke rates. We sought to compare stroke rates and determine stroke risk factors in HIV versus non-HIV patients. Methods An HIV cohort and matched non-HIV comparator cohort seen between 1996 and 2009 were identified from a Boston health care system. The primary endpoint was ischemic stroke, defined using International Classification of Diseases (ICD) codes. Unadjusted stroke incidence rates were calculated. Cox proportional hazards modeling was used to determine adjusted hazard ratios (HR). Results The incidence rate of ischemic stroke was 5.27 per 1000 person years (PY) in HIV compared with 3.75 in non-HIV patients, with an unadjusted HR of 1.40 (95% confidence interval [CI] 1.17-1.69, P<0.001). HIV remained an independent predictor of stroke after controlling for demographics and stroke risk factors (1.21, 1.01-1.46, P=0.043). The relative increase in stroke rates (HIV vs. non-HIV) was significantly higher in younger HIV patients (incidence rate ratio 4.42, 95% CI 1.56-11.09 age 18-29; 2.96, 1.69-4.96 age 30-39; 1.53, 1.06-2.17 age 40-49), and in women (HR 2.16 [1.53-3.04] for women vs. 1.18 [0.95-1.47] for men). Among HIV patients, increased HIV RNA (HR 1.10, 95% CI 1.04-1.17, P=0.001) was associated with an increased risk of stroke. Conclusions Stroke rates were increased among HIV-infected patients, independent of common stroke risk factors, particularly among young patients and women. PMID:22580566

In order to examine the character and phases of injury to the nervous system in HIV infection, 207 persons were observed. In 100, antibodies to the virus and to its separate proteins were discovered by immunofermentation analysis (IFA) reaction and by Western blot test. In 67, first phases of acute inflammation asymptomatic of persistent generalized lymphadenopathy were registered; and in 33, other ailments were found. In this group, which consisted of 74 men and 26 women aged 18-45, 91 were citizens of the Community of Independent States (15 of whom had served in the military) and 9 were citizens of other countries (4 had seen military duty). 75% of cases contracted the infection via sexual transmission. The control group comprised 65 seropositive people at the first screening confirmed by IFA but negative or doubtful by Western blot. Clinical laboratory and special psychological investigations were carried out using a 16-factor personality questionnaire and standard personality analysis methods. Generalized lymphadenopathy was found in 78%, hepatomegaly in 69%, chronic infection of the upper respiratory tract 67%, dermatological pathologies 33%, acute infections 32% (syphilis, hepatitis B), splenomegaly 20%, diarrhea and loss of more than 10% of body mass 11%. There was significant decrease of T-helper cells in 82.8%, in the correlation of the quality of T helper cells and T suppressor cells in 72.4%. In 67 persons who were in the second stage of HIV infection, there was a high frequency of pathological psychological symptoms. According to the personality scale, 60% had schizoid signs, 50% had depression, 40% had psychopathy, 30% had psychasthenia, and 20% had paranoia. When 33 persons in the second and third phase of the disease were measured, schizoid signs increased to 85.7%, depression to 78.6%, psychopathy to 57.1%, psychasthenia to 71.4%, and paranoia to 64.3%. In the first phases of the disease mainly hypochondria, depression, and hysteria predominated

Limited data exist on the burden of respiratory syncytial virus (RSV) illness among pregnant women, to determine their potential benefit from RSV vaccination. We evaluated the incidence of RSV illness from midpregnancy until 24 weeks postpartum in human immunodeficiency virus (HIV)-uninfected and HIV-infected women and their infants. Mother-infant dyads were enrolled in maternal influenza vaccine efficacy trials. These included 1060 and 1056 HIV-uninfected pregnant women in 2011 and 2012, respectively, 194 HIV-infected pregnant women in 2011, and their infants. Upper respiratory tract samples obtained at illness visits were tested for RSV. The incidence (per 1000 person-months) of RSV illness (n = 43 overall) among HIV-uninfected women was lower in 2011 (1.2; 95% confidence interval [CI], .6-2.2) than in 2012 (4.0; 95% CI, 2.8-5.6). The incidence of RSV illness (n = 5) in HIV-infected women was 3.4 (95% CI, 1.4-8.1). Maternal RSV infection was associated with respiratory symptoms including cough (72.1%), rhinorrhea (39.5%), sore throat (37.2%), and headache (42%), but fever was absent. RSV infection during pregnancy was not associated with adverse pregnancy outcomes. Postpartum, RSV infection in mothers (n = 27) was associated with concurrent infection among 51.9% of their infants and, conversely, 29.8% of mothers investigated within 7 days of their infants having an RSV illness also tested positive for RSV. RSV infection is associated with respiratory illness during pregnancy and postpartum. Vaccination of pregnant women against RSV could benefit the mother, albeit primarily against nonfebrile illness, and her infant. NCT01306669 and NCT01306682.

The objective of this study is to describe the burden of human papillomavirus (HPV) infection among women living with HIV and non-infected women in Ghana. A case-control study was conducted involving 107 women living with HIV aged between 18 and 59 years (cases) and 100 non-HIV-infected apparently healthy women (controls) who were recruited from the Kumasi South Hospital, from July to December, 2014. Cervicovaginal swabs were taken from study participants to characterise 28 high- and low-risk HPV genotypes using a multiplex real-time PCR. The overall mean age for the participants was 40.10 ± 9.76 years. The prevalence of high-risk (hr)-HPV genotypes was significantly higher among the cases than the controls (77.4% vs. 41.6%, P < 0.0001). Overall, HPV 58 and 54 were the most predominant high-risk (18.8%) and low-risk (15.0%) genotypes detected. The two most common hr-HPV genotype isolates were 58 (18.8%) and 35 (15.9%) with 58 being the most prevalent among age group 35-44 years compared with hr-HPV 16, 18, 35 and 45, found predominantly among 18-34 age group. Significant variations exist in HPV genotypes among HIV-infected and uninfected women. © 2015 John Wiley & Sons Ltd.

Hope and resilience in suicide ideation and behavior of gay and bisexual men following notification of HIV infection.

PubMed

Siegel, K; Meyer, I H

Upon being notified that they are positive for HIV, people often experience terror and confusion. At the beginning stages of coping with HIV diagnosis, suicide ideation and behavior may arise as the infected person begins to envision frightening images of a future life with AIDS. We examined the narratives of gay men who contemplated or attempted suicide soon after they had learned of their HIV infection. We found that suicidal ideation and attempt often provoked a process of coping with HIV disease, leading to a redefinition of the meaning of HIV, enhancing one's sense of control over life, and prompting a renewed effort at self-help and help seeking, a new commitment to life, and a reappraisal of personal goals. We recommend that clinicians and HIV counselors be cognizant of these positive symbolic functions of suicidality in coping with HIV infection. Allowing people who were recently diagnosed with HIV to discuss suicidality may allow them to move toward acceptance and commitment to life.

Objective: The aim of this study was to apply the HIV-associated neurocognitive disorders (HAND) criteria for diagnosing HAND in HIV-infected adults, in a cohort of HIV-infected youth to thus establish whether this system is able to detect a spectrum of neurocognitive disorders (ND) in HIV-infected youth. Methods: We used a comprehensive pediatric neurocognitive battery, an assessment of functional competence, and the American Academy of Neurology system for diagnosing ND in a cross-sectional study of HIV-infected youth (n = 86) and HIV-negative controls (n = 34) to establish whether this system could detect a spectrum of ND in HIV-infected youth (6–16 years). Results: Compared to a well-matched control group of HIV-negative youth, HIV-infected youth performed significantly more poorly on tests of Verbal IQ, Full Scale IQ, processing speed, finger tapping, verbal memory, expressive language, cognitive flexibility, and inhibition. HIV-infected youth were also more likely to have impaired total competence on the Child Behavior Checklist. Using the criteria for HAND, we found that 45.35% of the 86 HIV-infected youth could be diagnosed with an ND. Furthermore, youth with HIV encephalopathy (HIVE) were 9.4 times more likely to have a diagnosis of a major ND compared to HIV-infected youth without HIVE. Conclusions: The HAND criterion designed for adults was able to identify youth with important functional cognitive impairments who do not fit criteria for HIVE and would therefore not have been identified otherwise. This has major clinical implications regarding the importance of managing HIV-infected youth. PMID:27206720

Background The incidence of non-AIDS-defining malignancies (non-ADM) is reported as unchanged or increasing in the HAART era. Whether incidence of non-ADM is significantly higher in HIV-infected than in HIV-uninfected patients remains unclear. Methods Incidence rates of malignancies were calculated in a cohort of veterans in care for HIV-infected and age, race, and gender-matched uninfected patients from 1997 to 2004. For HIV-infected patients CD4 counts closest to first observation date were compared between those with and without cancer. Results 33,420 HIV-infected and 66,840 HIV-uninfected patients were followed for a median of 5.1 and 6.4 years. The Incidence rate ratio [IRR] of HIV-infected to HIV-uninfected was 1.6 (1260 vs. 841/100,000 person-years; 95% CI: 1.5–1.7). IRR for individual cancers was highest for anal cancer (14.9; CI: 10.1–22.1). Among HIV-infected patients, median CD4 counts were lower for those with non-ADM (249 vs. 270, p=0.02), anal cancer (154 vs. 270; p<0.001), and Hodgkin’s (217 vs. 270; p=0.03). Prostate cancer was associated with a higher CD4 count (310 vs. 270; p<0.001). Conclusions In the HAART era, the incidence of non-ADMs is higher among HIV-infected than HIV-uninfected patients, adjusting for age, race, and gender. Some non-ADMs do not appear to be associated with significantly lower CD4 counts. PMID:19617846

Tuberculosis is recognised as one of the leading causes of severe sepsis among HIV-infected patients. Most patients with Mycobacterium tuberculosis bacteraemia have advanced HIV disease with CD4 counts less than 100 cells/μl and its presentation is non-specific in most instances. This was a cross-sectional study which was done by analyzing data from 201 adult HIV-infected patients who met the inclusion criteria for severe sepsis. The prevalence of Mycobacterium tuberculosis bactraemia in the study population was 34.8%. Severe sepsis caused by other etiologies was observed in 33 (16.4%) of the participants. Concomitant infection of Mycobacterium tuberculosis bactraemia with other organisms is not uncommon in patients with severe sepsis. This cohort of HIV-infected patients had severe immunosuppression with a median CD4 count of 51 (20-136) cells/μl with moderate anaemia, mean haemoglobin 8.0 (3.0) g/dl, and were generally underweight with a mean mid upper arm circumference (MUAC) of 21.0 (3.4) cm. Mycobacterium tuberculosis bacteraemia is very common in HIV-infected patients with advanced HIV disease who present with severe sepsis. Mycobacterium tuberculosis bacteraemia co-infection with aerobic organisms is not uncommon. Factors that were independently associated with Mycobacterium tuberculosis bacteraemia in our study population were MUAC and sodium level.

The data on the dynamics of HIV infection in the Stavropol Territory beginning with 1987 are given. The situation became aggravated after 1996, and its sharp deterioration occurred in 2000 when 138 cases of HIV infection were detected and the area of this infection increased. In most cases patients became infected beyond the borders of the territory. About a half of the new cases of HIV infection registered in 2000 were detected in Ingushetia and Chechnya. The leading factor in the spread of HIV infection was the use of drugs by injection. The main trends of the prophylactic work are presented.

The incidence of cutaneous adverse drug reactions (CADRs) to first-line antituberculosis drugs (FLTDs) is higher in HIV-tuberculosis coinfection. However, the utility of patch testing to identify the offending drug in this patient subgroup has been poorly studied. To identify drugs causing adverse drug reactions in patients with HIV-tuberculosis coinfection. Fourteen consecutive patients underwent diagnostic work-up (patch testing followed by a skin prick test and an oral rechallenge) to pinpoint the offending drug after developing FLTD-associated CADR, which included drug rash with eosinophilia and systemic symptoms (n = 12), Stevens-Johnson syndrome (SJS, n = 1) and toxic epidermal necrolysis/SJS overlap (n = 1). A positive reaction to any of the three diagnostic modalities eliminated that drug from the regimen. Once patients were clinically stable postreaction, sequential and additive rechallenge with FLTDs was initiated. Eleven of the 14 participants with FLTD-associated CADR were HIV infected (median CD4 count 149 cells mm(-3) ). In this subgroup, patch testing resulted in generalized systemic reactions in 10 of 11 patients (91%). These included rash in 10 of 13 reactions (77%), eosinophilia in eight (62%), transaminitis in seven (54%) and fever in five (38%). Isoniazid caused six of 13 (46%) generalized systemic reactions, rifampicin four (31%), ethambutol two (15%) and pyrazinamide one reaction. Using the Common Terminology Criteria for Adverse Events, five of 13 reactions were mild, six were moderate and two were severe. There were no life-threatening or fatal reactions. In HIV-infected persons with tuberculosis-associated CADR, although patch-testing reactions to FLTD are common and tend to be associated with systemic features, they are not life threatening or fatal. These data inform clinical practice in HIV-endemic settings. © 2016 British Association of Dermatologists.

in the era of highly active antiretroviral therapy (HAART), human immunodeficiency virus (HIV)-infected persons have higher cardiovascular disease risk. Little is known about asymptomatic abnormalities in cardiac structure and function in this population. the Study to Understand the Natural History of HIV/AIDS in the Era of Effective Therapy (SUN Study) is a prospective, observational, multi-site cohort of 656 HIV-infected participants who underwent baseline echocardiography during 2004-2006. We examined prevalence of and factors associated with left ventricular systolic dysfunction (LVSD), diastolic dysfunction (DD), pulmonary hypertension (PHTN), left ventricular hypertrophy (LVH), and left atrial enlargement (LAE). participant characteristics were as follows: median age, 41 years; 24% women; 29% non-Hispanic black; 73% receiving HAART; and median CD4+ cell count, 462 cells/μL. Among evaluable participants, 18% had LVSD, 26% had DD, 57% had PHTN (right ventricular pressure >30 mm Hg), 6.5% had LVH, and 40% had LAE. In multivariate analyses, significant factors (P < .05) associated with LVSD were history of MI, elevated highly sensitive C-reactive protein (hsCRP) level, and current tobacco smoking; for DD, elevated hsCRP level and hypertension; for PHTN, current use of ritonavir; for LVH, hypertension, diabetes, non-white race, female sex with elevated body mass index, calculated as the weight in kilograms divided by the square of height in meters, of ≥ 25, elevated hsCRP level, and current use of abacavir; for LAE, hypertension and recent marijuana use. in this large contemporary HIV cohort, the prevalence of subclinical functional and structural cardiac abnormalities was greater than expected for age. Abnormalities were mostly associated with expected and often modifiable risks. Lifestyle modification should become a greater priority in the management of chronic HIV disease.

HIV-positive people have increased risk of infection-related malignancies (IRMs) and infection-unrelated malignancies (IURMs). The aim of the study was to determine the impact of aging on future IRM and IURM incidence. People enrolled in EuroSIDA and followed from the latest of the first visit or 1 January 2001 until the last visit or death were included in the study. Poisson regression was used to investigate the impact of aging on the incidence of IRMs and IURMs, adjusting for demographic, clinical and laboratory confounders. Linear exponential smoothing models forecasted future incidence. A total of 15 648 people contributed 95 033 person-years of follow-up, of whom 610 developed 643 malignancies [IRMs: 388 (60%); IURMs: 255 (40%)]. After adjustment, a higher IRM incidence was associated with a lower CD4 count [adjusted incidence rate ratio (aIRR) CD4 count < 200 cells/μL: 3.77; 95% confidence interval (CI) 2.59, 5.51; compared with ≥ 500 cells/μL], independent of age, while a CD4 count < 200 cells/μL was associated with IURMs in people aged < 50 years only (aIRR: 2.51; 95% CI 1.40-4.54). Smoking was associated with IURMs (aIRR: 1.75; 95% CI 1.23, 2.49) compared with never smokers in people aged ≥ 50 years only, and not with IRMs. The incidences of both IURMs and IRMs increased with older age. It was projected that the incidence of IRMs would decrease by 29% over a 5-year period from 3.1 (95% CI 1.5-5.9) per 1000 person-years in 2011, whereas the IURM incidence would increase by 44% from 4.1 (95% CI 2.2-7.2) per 1000 person-years over the same period. Demographic and HIV-related risk factors for IURMs (aging and smoking) and IRMs (immunodeficiency and ongoing viral replication) differ markedly and the contribution from IURMs relative to IRMs will continue to increase as a result of aging of the HIV-infected population, high smoking and lung cancer prevalence and a low prevalence of untreated HIV infection.

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.

Human immunodeficiency virus (HIV)-positive rural individuals carry a 1.3-times greater risk of a depressive diagnosis than their urban counterparts. This randomized clinical trial tested whether telephone-administered interpersonal psychotherapy (tele-IPT) acutely relieved depressive symptoms in 132 HIV-infected rural persons from 28 states diagnosed with Diagnostic and Statistical Manual of Mental Disorders-IV major depressive disorder (MDD), partially remitted MDD, or dysthymic disorder. Patients were randomized to either 9 sessions of one-on-one tele-IPT (n = 70) or standard care (SC; n = 62). A series of intent-to-treat (ITT), therapy completer, and sensitivity analyses assessed changes in depressive symptoms, interpersonal problems, and social support from pre- to postintervention. Across all analyses, tele-IPT patients reported significantly lower depressive symptoms and interpersonal problems than SC controls; 22% of tele-IPT patients were categorized as a priori "responders" who reported 50% or higher reductions in depressive symptoms compared to only 4% of SC controls in ITT analyses. Brief tele-IPT acutely decreased depressive symptoms and interpersonal problems in depressed rural people living with HIV.

Hepatitis B (HBV) and C (HCV) are important causes of morbidity and mortality in people living with human immunodeficiency virus (HIV). The burden of these co-infections in sub-Saharan Africa is still unclear. We estimated the prevalence of the hepatitis B surface antigen (HBsAg) and hepatitis C antibody (HCVAb) among HIV-infected individuals in Rwanda and identified factors associated with infection. Between January 2016 and June 2016, we performed systematic screening for HBsAg and HCVAb among HIV-positive individuals enrolled at public and private HIV facilities across Rwanda. Results were analyzed to determine marker prevalence and variability by demographic factors. Overall, among 117,258 individuals tested, the prevalence of HBsAg and HCVAb was 4.3% (95% confidence interval [CI] (4.2-4.4) and 4.6% (95% CI 4.5-4.7) respectively; 182 (0.2%) HIV+ individuals were co-infected with HBsAg and HCVAb. Prevalence was higher in males (HBsAg, 5.4% [5.1-5.6] vs. 3.7% [3.5-3.8]; HCVAb, 5.0% [4.8-5.2] vs. 4.4% [4.3-4.6]) and increased with age; HCVAb prevalence was significantly higher in people aged ≥65 years (17.8% [16.4-19.2]). Prevalence varied geographically. HBV and HCV co-infections are common among HIV-infected individuals in Rwanda. It is important that viral hepatitis prevention and treatment activities are scaled-up to control further transmission and reduce the burden in this population. Particular efforts should be made to conduct targeted screening of males and the older population. Further assessment is required to determine rates of HBV and HCV chronicity among HIV-infected individuals and identify effective strategies to link individuals to care and treatment.

The availability of an increasing number of antiretroviral agents and the rapid evolution of new information have introduced substantial complexity into treatment regimens for persons infected with human immunodeficiency virus (HIV). In 1996, the Department of Health and Human Services and the Henry J. Kaiser Family Foundation convened the Panel on Clinical Practices for the Treatment of HIV to develop guidelines for clinical management of HIV-infected adults and adolescents (CDC. Report of the NIH Panel To Define Principles of Therapy of HIV Infection and Guidelines for the use of antiretroviral agents in HIV-infected adults and adolescents. MMWR. 1998;47[RR-5]:1-41). This report, which updates the 1998 guidelines, addresses 1) using testing for plasma HIV ribonucleic acid levels (i.e., viral load) and CD4+ T cell count; 2) using testing for antiretroviral drug resistance; 3) considerations for when to initiate therapy; 4) adherence to antiretroviral therapy; 5) considerations for therapy among patients with advanced disease; 6) therapy-related adverse events; 7) interruption of therapy; 8) considerations for changing therapy and available therapeutic options; 9) treatment for acute HIV infection; 10) considerations for antiretroviral therapy among adolescents; 11) considerations for antiretroviral therapy among pregnant women; and 12) concerns related to transmission of HIV to others. Antiretroviral regimens are complex, have serious side effects, pose difficulty with adherence, and carry serious potential consequences from the development of viral resistance because of nonadherence to the drug regimen or suboptimal levels of antiretroviral agents. Patient education and involvement in therapeutic decisions are critical. Treatment should usually be offered to all patients with symptoms ascribed to HIV infection. Recommendations for offering antiretroviral therapy among asymptomatic patients require analysis of real and potential risks and benefits. In general

Disclosure of HIV Diagnosis to HIV-Infected Children in South Africa: Focus Groups for Intervention Development

Worldwide about 2.5 million children younger than 15 years of age are living with HIV, and more than 2.3 million of them live in sub-Saharan Africa. Antiretroviral therapy has reduced mortality among HIV-infected children, and as they survive into adolescence, disclosing to them their diagnosis has emerged as a difficult issue, with many adolescents unaware of their diagnosis. There is a need to build an empirical foundation for strategies to appropriately inform infected children of their diagnosis, particularly in South Africa, which has the largest number of HIV-positive people in the world. As a step toward developing such strategies, we conducted a study in Eastern Cape Province, South Africa to identify beliefs about disclosing HIV diagnosis to HIV-infected children among caregivers, health-care providers, and HIV-positive children who knew their diagnosis. We implemented 7 focus groups with 80 participants: 51 caregivers in 4 groups, 24 health-care providers in 2 groups, and 5 HIV-positive children in 1 group. We found that although the participants believed that children from age 5 years should begin to learn about their illness, with full disclosure by age 12, they suggested that many caregivers fail to fully inform their children. The participants said that the primary caregiver was the best person to disclose. The main reasons cited for failing to disclose were (a) lack of knowledge about HIV and its treatment, (b) the concern that the children might react negatively, and (c) the fear that the children might inappropriately disclose to others, which would occasion gossip, stigmatization, and discrimination towards them and the family. We discuss the implications for developing interventions to help caregivers appropriately disclose HIV status to HIV-infected children and, more generally, communicate effectively with the children to improve their health outcomes.

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.

T Follicular Helper Cells and B Cell Dysfunction in Aging and HIV-1 Infection

Pallikkuth, Suresh; de Armas, Lesley; Rinaldi, Stefano; Pahwa, Savita

T follicular helper (Tfh) cells are a subset of CD4 T cells that provide critical signals to antigen-primed B cells in germinal centers to undergo proliferation, isotype switching, and somatic hypermutation to generate long-lived plasma cells and memory B cells during an immune response. The quantity and quality of Tfh cells therefore must be tightly controlled to prevent immune dysfunction in the form of autoimmunity and, on the other hand, immune deficiency. Both Tfh and B cell perturbations appear during HIV infection resulting in impaired antibody responses to vaccines such as seasonal trivalent influenza vaccine, also seen in biologic aging. Although many of the HIV-associated defects improve with antiretroviral therapy (ART), excess immune activation and antigen-specific B and T cell responses including Tfh function are still impaired in virologically controlled HIV-infected persons on ART. Interestingly, HIV infected individuals experience increased risk of age-associated pathologies. This review will discuss Tfh and B cell dysfunction in HIV infection and highlight the impact of chronic HIV infection and aging on Tfh–B cell interactions. PMID:29109730

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

We analyzed data on reported mode of transmission in case reports of HIV-infections among men in Ukraine. The number of men who were reported to have acquired HIV through heterosexual transmission increased substantially in 2006-2011. However, we estimate that up to 40 % of reported cases of heterosexual transmission among men may actually represent misclassified men who have sex with men or persons who inject drugs. These findings indicate a need to improve the quality of data on reported mode of HIV transmission. Accurate information has important public health implications in planning prevention and treatment services.

CCD Camera Detection of HIV Infection.

Day, John R

2017-01-01

Rapid and precise quantification of the infectivity of HIV is important for molecular virologic studies, as well as for measuring the activities of antiviral drugs and neutralizing antibodies. An indicator cell line, a CCD camera, and image-analysis software are used to quantify HIV infectivity. The cells of the P4R5 line, which express the receptors for HIV infection as well as β-galactosidase under the control of the HIV-1 long terminal repeat, are infected with HIV and then incubated 2 days later with X-gal to stain the infected cells blue. Digital images of monolayers of the infected cells are captured using a high resolution CCD video camera and a macro video zoom lens. A software program is developed to process the images and to count the blue-stained foci of infection. The described method allows for the rapid quantification of the infected cells over a wide range of viral inocula with reproducibility, accuracy and at relatively low cost.

The objective is to clarify the role of immunodeficiency and pneumonia in elevated lung cancer risk among HIV-infected individuals. Cohort study of HIV-infected and HIV-uninfected adults in a large integrated healthcare system in California during 1996-2011. We used Poisson models to obtain rate ratios for lung cancer associated with HIV infection, overall and stratified by recent CD4 cells/μl (HIV-uninfected as reference group), with χ tests for trends across CD4 strata. Fully adjusted models included demographics, cancer risk factors (smoking, drug/alcohol abuse, overweight/obesity), and prior pneumonia. Among 24 768 HIV-infected and 257 600 HIV-uninfected individuals, the lung cancer rate per 100 000 person-years was 66 (n = 80 events) for HIV-infected and 33 (n = 506 events) for HIV-uninfected individuals [rate ratio 2.0, 95% confidence interval (CI): 1.7-2.2]. Overall, HIV-infected individuals were at increased risk of lung cancer after adjustment for demographics and cancer risk factors (rate ratio 1.4, 95% CI: 1.1-1.7), but not after additional adjustment for pneumonia (rate ratio 1.2, 95% CI: 0.9-1.6). Lower CD4 cell counts were associated with higher risk of lung cancer in unadjusted and demographics-adjusted models (P < 0.001 for all), but this trend did not remain after adjustment for cancer risk factors and pneumonia. Compared with HIV-uninfected individuals, HIV-infected individuals with CD4 less than 200 cells/μl were not at increased risk of lung cancer in fully adjusted models. The increased lung cancer risk among HIV patients is attributable to differences in demographics, risk factors such as smoking, and history of pneumonia. Immunodeficiency does not appear to have an independent effect on lung cancer risk.

Health-related quality of life (QOL) has become a high priority of long-term management of HIV-infected individuals. The newly diagnosed HIV cases were assessed to obtain sociodemographic and clinical findings. Eyesenk Personality Questionnaire (EPQ), World Health Organization Quality of Life Brief (WHOQOL-BREF) for HIV-infected patients, and Beck Depression Inventory (BDI) were used to get data regarding personality traits, QOL, and depression scores. A total of 175 patients were included in the study, 128 (73.1%) men and 47 (26.9%) women. Overall 56% of patients screened positive for depression. Presence of depression and high neuroticism score in the personality profile of HIV-infected patients are significantly associated with poorer QOL. High neuroticism score was a strong predictor of poorer QOL in psychological and spiritual domain. Management of HIV-infected patients therefore needs to address these psychological issues.

Persons engaged in the sex industry are at greater risk of HIV and other sexually transmitted infections than the general population. One major factor is exposure to higher levels of risky sexual activity. Expanding condom use is a critical prevention strategy, but this requires negotiation with those buying sex, which takes place in the context of cultural and economic constraints. Impoverished individuals who fear violence are more likely to forego condoms. Here we tested the hypotheses that poverty and fear of violence are two structural drivers of HIV infection risk in the sex industry. Using data from the European Centre for Disease Prevention and Control and the World Bank for 30 countries, we evaluated poverty, measured using the average income per day per person in the bottom 40% of the income distribution, and gender violence, measured using homicide rates in women and the proportion of women exposed to violence in the last 12 months and/or since age 16 years. We found that HIV prevalence among those in the sex industry was higher in countries where there were greater female homicide rates (β = 0.86; P = 0.018) and there was some evidence that self-reported exposure to violence was also associated with higher HIV prevalence (β = 1.37; P = 0.043). Conversely, HIV prevalence was lower in countries where average incomes among the poorest were greater (β = -1.05; P = 0.046). Our results are consistent with the theory that reducing poverty and exposure to violence may help reduce HIV infection risk among persons engaged in the sex industry. © 2017 British HIV Association.

In many individuals, drug abuse is intimately linked with HIV-1 infection. In addition to being associated with one-third of all HIV-1 infections in the United States, drug abuse also plays a role in disease progression and severity in HIV-1-infected patients, including adverse effects on the central nervous system (CNS). Specific systems within the brain are known to be damaged in HIV-1-infected individuals and this damage is similar to that observed in drug abuse. Even in the era of anti-retroviral therapy (ART), CNS pathogenesis occurs with HIV-1 infection, with a broad range of cognitive impairment observed, collectively referred to as HIV-1-associated neurocognitive disorders (HAND). A number of HIV-1 proteins (Tat, gp120, Nef, Vpr) have been implicated in the etiology of pathogenesis and disease as a result of the biologic activity of the extracellular form of each of the proteins in a number of tissues, including the CNS, even in ART-suppressed patients. In this review, we have made Tat the center of attention for a number of reasons. First, it has been shown to be synthesized and secreted by HIV-1-infected cells in the CNS, despite the most effective suppression therapies available to date. Second, Tat has been shown to alter the functions of several host factors, disrupting the molecular and biochemical balance of numerous pathways contributing to cellular toxicity, dysfunction, and death. In addition, the advantages and disadvantages of ART suppression with regard to controlling the genesis and progression of neurocognitive impairment are currently under debate in the field and are yet to be fully determined. In this review, we discuss the individual and concerted contributions of HIV-1 Tat, drug abuse, and ART with respect to damage in the CNS, and how these factors contribute to the development of HAND in HIV-1-infected patients.

Context Reducing HIV incidence in the United States and improving health outcomes for people living with HIV hinge on improving access to highly effective treatment and overcoming barriers to continuous treatment. Using laboratory tests routinely reported for HIV surveillance to monitor individuals’ receipt of HIV care and contacting them to facilitate optimal care could help achieve these objectives. Historically, surveillance-based public health intervention with individuals for HIV control has been controversial because of concerns that risks to privacy and autonomy could outweigh benefits. But with the availability of lifesaving, transmission-interrupting treatment for HIV infection, some health departments have begun surveillance-based outreach to facilitate HIV medical care. Methods Guided by ethics frameworks, we explored the ethical arguments for changing the uses of HIV surveillance data. To identify ethical, procedural, and strategic considerations, we reviewed the activities of health departments that are using HIV surveillance data to contact persons identified as needing assistance with initiating or returning to care. Findings Although privacy concerns surrounding the uses of HIV surveillance data still exist, there are ethical concerns associated with not using HIV surveillance to maximize the benefits from HIV medical care and treatment. Early efforts to use surveillance data to facilitate optimal HIV medical care illustrate how the ethical burdens may vary depending on the local context and the specifics of implementation. Health departments laid the foundation for these activities by engaging stakeholders to gain their trust in sharing sensitive information; establishing or strengthening legal, policy and governance infrastructure; and developing communication and follow-up protocols that protect privacy. Conclusions We describe a shift toward using HIV surveillance to facilitate optimal HIV care. Health departments should review the

The course of the combined infection (tuberculosis plus HIV-infection) has been analysed in 41 patients. Of them, 24 patients developed tuberculosis in the presence of HIV-infection (group 1) and 17 were infected with HIV when they already had tuberculosis running up to 5 years. HIV-infection in group 1 ran a more severe course, the patients developed generalized, disseminated and complicated forms of tuberculosis with more frequent lethal outcome. 39 patients of both groups received specific antituberculous therapy including 1-5 drugs. A response to treatment was achieved in 23 (60%) patients (52 and 47.8% at early and late HIV-infection stages, respectively). Treatment failure was explained by development of severe opportunistic infections and secondary diseases (generalized cytomegalovirus infection, advanced candidiasis, toxoplasmosis), poor compliance, asocial life style, advanced tuberculosis process, late diagnosis, inadequate treatment. It is shown that in late HIV-infection positive results of treatment can be expected only in early detection of tuberculosis and active long-term treatment.

Background. Little is known about the associations between CD4+ cell counts, human immunodeficiency virus (HIV) load, and human papillomavirus “low-risk” types in noncancerous clinical outcomes. This study examined whether CD4+ count and HIV load predict the size of the largest anal warts in 976 HIV-infected women in an ongoing cohort. Methods. A linear mixed model was used to determine the association between size of anal wart and CD4+ count and HIV load. Results. The incidence of anal warts was 4.15 cases per 100 person-years (95% confidence interval [CI], 3.83–4.77) and 1.30 cases per 100 person-years (95% CI, 1.00–1.58) in HIV-infected and HIV-uninfected women, respectively. There appeared to be an inverse association between size of the largest anal warts and CD4+ count at baseline; however, this was not statistically significant. There was no association between size of the largest anal warts and CD4+ count or HIV load over time. Conclusions. There was no evidence for an association between size of the largest anal warts and CD4+ count or HIV load over time. Further exploration on the role of immune response on the development of anal warts is warranted in a larger study. PMID:22246682

Background.  Vaccination provides long-term immunity to hepatitis A virus (HAV) among the general population, but there are no such data regarding vaccine durability among human immunodeficiency virus (HIV)–infected adults. Methods.  We retrospectively studied HIV-infected adults who had received 2 doses of HAV vaccine. We analyzed blood specimens taken at 1 year, 3 years, and, when available, 6–10 years postvaccination. HAV immunoglobulin G (IgG) values of ≥10 mIU/mL were considered seropositive. Results.  We evaluated specimens from 130 HIV-infected adults with a median age of 35 years and a median CD4 cell count of 461 cells/mm3 at or before time of vaccination. Of these, 49% had an HIV RNA load <1000 copies/mL. Initial vaccine responses were achieved in 89% of HIV-infected adults (95% confidence interval [CI], 83%–94%), compared with 100% (95% CI, 99%–100%) of historical HIV-uninfected adults. Among initial HIV-infected responders with available specimens, 90% (104 of 116; 95% CI, 83%–95%) remained seropositive at 3 years and 85% (63 of 74; 95% CI, 75%–92%) at 6–10 years. Geometric mean concentrations (GMCs) among HIV-infected adults were 154, 111, and 64 mIU/mL at 1, 3, and 6–10 years, respectively, compared with 1734, 687, and 684 mIU/mL among HIV-uninfected persons. Higher GMCs over time among HIV-infected adults were associated with lower log10 HIV RNA levels (β = −.12, P = .04). Conclusions.  Most adults with well-controlled HIV infections had durable seropositive responses up to 6–10 years after HAV vaccination. Suppressed HIV RNA levels are associated with durable HAV responses. PMID:21606540

Mucosal Immunology of HIV Infection

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

The magnitude of intestinal parasitic infection in acquired immunodeficiency syndrome patients requires careful consideration in the developing world where poor nutrition is associated with poor hygiene and several tropical diseases. However, there have been very few studies addressing this issue in Cameroon. This study was conducted to determine the prevalence of intestinal parasitosis in HIV/AIDS patients in Dschang -Cameroon. Stool and blood specimens from HIV/AIDS patients and control group were screened respectively for intestinal parasites and for HIV antibodies. Intestinal parasites were identified using direct microscopy, formalin-ether concentration and Ziehl Neelsen methods. Out of 396 participants recruited among patients consulting at hospital, 42 (10.6%) were HIV positive, thirty of them treatment naïve. The overall prevalence of intestinal parasites was 14.64%. Out of 42 HIV/AIDS patients, 59.5% (25/42) were infected with intestinal parasites, while only 9.32% (33/354) of the HIV negative patients were infected with intestinal parasites. The parasites detected in our study population included Crystosporidium parvum (2.53%), Entamoeba histolytica (7.52%), Entamoeba coli (4.04%), Giardia lamblia (0.25%), Trichuris trichura (0.25%), Strongyloides stercoralis (0.25%) and Taenia spp. (0.25%). In the HIV infected group, Crystosporidium parvum (19.04%), Entamoeba histolytica (19.04%), Entamoeba coli (21.42%), Giardia lamblia (2.38%), Strongyloides stercoralis (0.25%) and Taenia spp. (0.25%) were found. Crystosporidium parvum was found to be significantly higher in HIV/AIDS patients than in controls (P<0.05). Multivariate analysis showed that the HIV status and the quality of water were the major risk factors for intestinal parasitosis. Routine examinations of stool samples for parasites would significantly benefit the HIV patients by contributing in reducing morbidity and improving the efficiency of antiretroviral treatment.

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. Copyright © 2015 Elsevier Ltd.

To add to the limited information on infective endocarditis (IE) not related to intravenous drug abuse (IVDA) in HIV-1-infected patients. We have reviewed the characteristics of eight cases of IE in non-IVDA HIV-1 infected patients diagnosed in our institution between 1979 and 1999 as well as cases in the literature. All our patients were male, and the mean age was 44 years (range 29-64). HIV-1 risk factors were: homosexuality in five, heterosexuality in two, and the use of blood products in one. HIV stage C was found in six cases, and the median (range) CD4 cell count was 22/microL (4-274 cells/microL). IE was caused by Enterococcus faecalis in three cases, staphylococci in two cases, and Salmonella enteritidis, viridans group streptococci and Coxiella burnetii in one case each. Three patients acquired IE while in the hospital. All IE cases involved a native valve, and underlying valve disease was found in three patients. The aortic valve was the most frequently affected (five cases). Two patients underwent surgery, with a good outcome, and one patient died. Fourteen cases of IE not related to IVDA in HIV-1-infected patients were found in the literature review. The most common causative agents were Salmonella spp. and fungi (four cases each). Two patients had prosthetic valve IE, and the mitral valve was the most frequently affected (10 cases). The remaining clinical characteristics and the outcome were similar to those in the present series. IE not related to IVDA is rare in HIV-1-infected patients. In more than half of the cases, IE develops in patients with advanced HIV-1 disease. A wide etiologic range is found, reflecting different clinical and environmental conditions. None of the patients who underwent surgery died, and the overall mortality rate was not higher than in non-HIV-1-infected patients with IE.

Intact HIV-1 and exosomes can be internalized by dendritic cells (DCs) through a common pathway leading to their transmission to CD4 + T lymphocytes by means of mechanisms defined as trans-infection and trans-dissemination, respectively. We previously reported that exosomes from HIV-1-infected cells activate both uninfected quiescent CD4 + T lymphocytes, which become permissive to HIV-1, and latently infected cells, with release of HIV-1 particles. However, nothing is known about the effects of trans-dissemination of exosomes produced by HIV-1-infected cells on uninfected or latently HIV-1-infected CD4 + T lymphocytes. Here, we report that trans-dissemination of exosomes from HIV-1-infected cells induces cell activation in resting CD4 + T lymphocytes, which appears stronger with mature than immature DCs. Using purified preparations of both HIV-1 and exosomes, we observed that mDC-mediated trans-dissemination of exosomes from HIV-1-infected cells to resting CD4 + T lymphocytes induces efficient trans-infection and HIV-1 expression in target cells. Most relevant, when both mDCs and CD4 + T lymphocytes were isolated from combination anti-retroviral therapy (ART)-treated HIV-1-infected patients, trans-dissemination of exosomes from HIV-1-infected cells led to HIV-1 reactivation from the viral reservoir. In sum, our data suggest a role of exosome trans-dissemination in both HIV-1 spread in the infected host and reactivation of the HIV-1 reservoir.

Measles infection remains a serious threat to child survival in the developing world despite vaccination and treatment with vitamin A. This report reviews the epidemiology of measles in HIV-infected children in Africa. In hospitalized infants, the rate of malnutrition before measles and the rate of death after measles are both higher in HIV-positive than in HIV-negative infants. However, the rates of pneumonia and diarrhea in infants hospitalized with measles are the same in HIV-positive as in HIV-negative infants. In an autopsy study, measles was associated with death in HIV-positive children, only for those over 15 months of age. A cohort study found that infants of HIV-positive women were more likely than infants of HIV-negative women to have measles before 9 months of age, although the rates of complications did not differ between the two groups. The HIV status of the infants and the measles serology were too incomplete to draw firm conclusions, though only 1 of 54 infants tested was seropositive for measles at 6 months of age. In the context of the HIV epidemic, further work is needed to determine the risk of measles and its complications in HIV-positive infants and the optimal age of measles immunization.

Abstract Background. A “seek-test-treat” intervention (ARISTOTLE) was implemented in response to an outbreak of human immunodeficiency virus (HIV) infection among persons who inject drugs (PWID) in Athens. We assess trends in HIV incidence, prevalence, risk behaviors and access to prevention/treatment. Methods. Methods included behavioral data collection, provision of injection equipment, HIV testing, linkage to opioid substitution treatment (OST) programs and HIV care during 5 rounds of respondent-driven sampling (2012–2013). HIV incidence was estimated from observed seroconversions. Results. Estimated coverage of the target population was 88% (71%–100%; 7113 questionnaires/blood samples from 3320 PWID). The prevalence of HIV infection was 16.5%. The incidence per 100 person-years decreased from 7.8 (95% confidence interval, 4.6–13.1) (2012) to 1.7 (0.55–5.31) (2013; P for trend = .001). Risk factors for seroconversion were frequency of injection, homelessness, and history of imprisonment. Injection at least once daily declined from 45.2% to 18.8% (P < .001) and from 36.8% to 26.0% (P = .007) for sharing syringes, and the proportion of undiagnosed HIV infection declined from 84.3% to 15.0% (P < .001). Current OST increased from 12.2% to 27.7% (P < .001), and 48.4% of unlinked seropositive participants were linked to HIV care through 2013. Repeat participants reported higher rates of adequate syringe coverage, linkage to HIV care and OST. Conclusions. Multiple evidence-based interventions delivered through rapid recruitment in a large proportion of the population of PWID are likely to have helped mitigate this HIV outbreak. PMID:28407106

Cyclophilin B enhances HIV-1 infection

DOE Office of Scientific and Technical Information (OSTI.GOV)

DeBoer, Jason; Madson, Christian J.; Belshan, Michael, E-mail: michaelbelshan@creighton.edu

Cyclophilin B (CypB) is a member of the immunophilin family and intracellular chaperone. It predominantly localizes to the ER, but also contains a nuclear localization signal and is secreted from cells. CypB has been shown to interact with the Gag protein of human immunodeficiency type 1 (HIV-1). Several proteomic and genetic studies identified it as a potential factor involved in HIV replication. Herein, we show that over-expression of CypB enhances HIV infection by increasing nuclear import of viral DNA. This enhancement was unaffected by cyclosporine treatment and requires the N-terminus of the protein. The N-terminus contains an ER leader sequence,more » putative nuclear localization signal, and is required for secretion. Deletion of the N-terminus resulted in mislocalization from the ER and suppression of HIV infection. Passive transfer experiments showed that secreted CypB did not impact HIV infection. Combined, these experiments show that intracellular CypB modulates a pathway of HIV nuclear import. - Highlights: • CypB has been identified in several proteomic studies of HIV-1 infection. • CypB expression is upregulated in activated and infected T-cells. • Over-expression of CypB enhances HIV nuclear import and infection. • The N-terminus of CypB is necessary for these effects.« less

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

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.

Background HIV-infected individuals recently released from incarceration have suboptimal linkage and engagement in community HIV care. We conducted a study to evaluate an information and communication technology intervention to increase linkage to community care among HIV-infected persons recently involved in the criminal justice (CJ) system. Baseline characteristics including risk behaviors and HIV care indicators are reported and stratified by gender. Methods We recruited HIV-infected individuals in the District of Columbia jail and persons with a recent history of incarceration through community and street outreach. Participants completed a baseline computer-assisted personal interview regarding HIV care and antiretroviral treatment (ART) adherence, substance use, and sexual behaviors. CD4 and HIV plasma viral load testing were performed at baseline or obtained through medical records. Data were analyzed for the sample overall and stratified by gender. Results Of 110 individuals, 70% were community-enrolled, mean age was 40 (SD = 10.5), 85% were Black, and 58% were male, 24% female, and 18% transgender women. Nearly half (47%) had condomless sex in the three months prior to incarceration. Although drug dependence and hazardous alcohol use were highly prevalent overall, transgender women were more likely to have participated in drug treatment than men and women (90%, 61%, and 50% respectively; p = 0.01). Prior to their most recent incarceration, 80% had an HIV provider and 91% had ever taken ART. Among those, only 51% reported ≥90% ART adherence. Fewer women (67%) had received HIV medications during their last incarceration compared to men (96%) and transgender women (95%; p = 0.001). Although neither was statistically significant, transgender women and men had higher proportions of baseline HIV viral suppression compared to women (80%, 69%, and 48.0% respectively, p>0.05); a higher proportion of women had a CD4 count ≤200 compared to men and transgender

As a population, persons with serious mental illness (SMI) have an elevated risk for HIV infection. However, relatively little is known about how the risk of HIV has affected their lives, how persons with SMI evaluate their HIV risk, and what preventive measures they undertake. Furthermore, relatively little is known about community-based HIV prevention for persons with SMI as most interventions have been restricted to clinical settings. This report presents findings on the HIV-related experiences of persons with SMI living in supportive housing programs, one possible setting for implementing community-based HIV prevention with this population. The qualitative investigation interviewed 41 men and women living in five supportive housing programs. In-depth, qualitative interviews elicited discussion of research participants’ (a) experiences with HIV, (b) knowledge about HIV and HIV prevention, (c) assessments of their own risk, (d) descriptions of how they apply their prevention knowledge, and (e) reports of barriers for HIV prevention. Research participants describe social networks that have substantial contact with persons affected by HIV. However, contrary to some expectations of persons with SMI, research participants report using HIV prevention knowledge in negotiating their risk of contracting HIV. The implications of these findings are discussed in terms of their relevance for implementing community-based HIV prevention for persons with SMI. PMID:16389505

Sjogren's syndrome is an autoimmune disease that is characterized by dryness of the mouth and eyes. The loss of salivary and lacrimal gland function is accompanied by lymphocytic infiltration. Because similar symptoms and glandular pathology are observed in certain persons infected with human immunodeficiency virus (HIV), a search was initiated for a possible retroviral etiology in this syndrome. A human intracisternal A-type retroviral particle that is antigenically related to HIV was detected in lymphoblastoid cells exposed to homogenates of salivary tissue from patients with Sjogren's syndrome. Comparison of this retroviral particle to HIV indicates that they are distinguishable by several ultrastructural, physical, and enzymatic criteria.

Posttreatment control of HIV infection is a rare phenomenon primarily described among those initiating treatment with antiretroviral therapy (ART) during early/acute HIV infection. We examined a large, well-characterized cohort of HIV-infected Department of Defense beneficiaries for the presence of posttreatment controllers (PTCs) whom we defined as individuals with sustained viral suppression for ≥6 months after discontinuation of ART. We defined those who became viremic within 6 months of discontinuing ART as rapid viremics (RVs) and compared demographic and clinical characteristics, CD4 counts, and viral loads prior, during, and after ART discontinuation between the 2 groups. From a cohort of 6070 patients, we identified 95 who had been treated with ART for 2 years or more who subsequently discontinued ART and had viral load assessments available after discontinuation. Four (4.2%) of these 95 met our definition of PTC. The duration of viral suppression off of ART ranged from 267 to 1058 days with 1 of the 4 restarting ART without having redeveloped a significant viremia. All 4 patients initiated ART during chronic HIV infection. Demographic and clinical characteristics of PTCs were similar to RVs. While posttreatment control has predominantly been described among individuals who initiated ART in early/acute HIV infection, we identified 4 PTCs who started ART during chronic infection suggesting that posttreatment control also occurs among such patients. The rarity of PTCs identified in our cohort is consistent with reports from previous studies.

There is a reemergence of syphilis in the Latin American and Caribbean region. There is also very little information about HIV/Syphilis co-infection and its determinants. The aim of this study is to investigate knowledge, attitudes, and practices regarding sexually transmitted infections (STIs), in particular syphilis infection and HIV/Syphilis co-infection, as well as to estimate the prevalence of syphilis among men who have sex with men (MSM) in a city with one of the highest HIV prevalence rates in Ecuador. In this study, questionnaires were administered to 291 adult MSM. Questions included knowledge about STIs and their sexual practices. Blood samples were taken from participants to estimate the prevalence of syphilis and HIV/syphilis co-infection. In this population, the prevalence of HIV/syphilis co-infection was 4.8%, while the prevalence of syphilis as mono-infection was 6.5%. Participants who had syphilis mono-infection and HIV/syphilis co-infection were older. Men who had multiple partners and those who were forced to have sex had increased odds of syphilis and HIV/syphilis co-infection. A high prevalence of syphilis and self-reported STI was observed, which warrants targeted behavioral interventions. Co-infections are a cause for concern when treating a secondary infection in a person who is immunocompromised. These data suggest that specific knowledge, attitudes, and behaviors among MSM are associated with increased odds of STIs (including HIV/syphilis co-infections) in this region of Ecuador.

HIV-positive individuals are at higher risk than healthy persons for aging-related diseases, including myocardial infarction and non-AIDS defining cancers. Recent evidence suggests that HIV infection may modulate changes in the host cell epigenome, and these changes represent a potential mechanism through which HIV infection accelerates aging. We assessed the difference in DNA methylation (DNAm) age, an aging marker involving multiple age-related cytosine-guanine dinucleotide (CpG) sites, among antiretroviral treatment (ART)-naive HIV-positive and HIV-negative individuals in a cohort of veterans from the Veterans Aging Cohort Study. Peripheral blood samples were collected from 19 ART-naive, HIV-positive, and 19 HIV-negative male participants, matched by age and race. Blood samples were collected from HIV-positive participants 7-11 years after ART initiation. We compared DNAm age between HIV-positive and HIV-negative groups at baseline and between HIV-positive patients at baseline and follow-up. We also performed an epigenome-wide analysis to identify CpG methylation sites associated with HIV infection. DNAm age in HIV-positive individuals is, on average, 11.2 years higher than HIV study participants at baseline, and two of 10 HIV-positive individuals showed an increase in DNAm age after ART initiation. Epigenome-wide association studies showed an association of HIV infection with one site, in gene VPS37B, which approached statistical significance in our cohort (P = 3.30 × 10, Bonferroni-corrected threshold = 1.22 × 10) and was replicated in a second, larger cohort. ART treatment-naive HIV-positive individuals have significantly older DNAm age compared to HIV-negative individuals in the Veterans Aging Cohort Study cohort. Longitudinal changes in DNAm age are highly variable across individuals after initiation of antiretroviral therapy.

Human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) had a major impact on health problemin Indonesia. HIV type 1 (HIV-1) epidemic is currently infected with HIV viruses developing rapidly in Indonesia.Papua provinces have the highest prevalence rate of human immunodeficiency virus type 1 (HIV-1) infection in Indonesia; however, data on opportunistic infection of HIV-1 are limited. The study using medical records as a research sample was conducted among HIV patients from January 2013 - December 2014 in Sele be Solu hospital among 49 patients. Opportunistic infections commonly occur in HIV-infected patients. The aim of the study was to know theprevalence of opportunistic infection among HIV positive patients in West Papua. Forty-nine HIV-1 patients were collected in Sele be Solu Hospital, West Papua.Opportunistic infection was identified such as tuberculosis, tuberculosis Pulmo, tuberculosis and candidiasis, candidiasis and diarrhea. The clinical sign appeared in HIV infected patients such as itchy, cough and loss weight. The prevalence of opportunistic infection indicated the necessity of monitoring the opportunistic infection of HIV/AIDS patients in Indonesia.

Disability among long-term methamphetamine (MA) users is multifactorial. This study examined the additive adverse impact of human immunodeficiency virus (HIV) infection, a common comorbidity in MA users, on functional dependence. A large cohort of participants (N = 798) stratified by lifetime MA-dependence diagnoses (ie, MA+ or MA-) and HIV serostatus (ie, HIV+ or HIV-) underwent comprehensive baseline neuromedical, neuropsychiatric, and functional research evaluations, including assessment of neurocognitive symptoms in daily life, instrumental and basic activities of daily living, and employment status. Independent, additive effects of MA and HIV were observed across all measures of functional dependence, independent of other demographic, psychiatric, and substance-use factors. The prevalence of global functional dependence increased in the expected stepwise fashion across the cohort, with the lowest rates in the MA-/HIV- group (29%) and the highest rates in the MA+/HIV+ sample (69%). The impact of HIV on MA-associated functional dependence was moderated by nadir CD4 count, such that polysubstance use was associated with greater disability among those HIV-infected persons with higher but not lower nadir CD4 count. Within the MA+/HIV+ cohort, functional dependence was reliably associated with neurocognitive impairment, lower cognitive reserve, polysubstance use, and major depressive disorder. HIV infection confers an increased concurrent risk of MA-associated disability, particularly among HIV-infected persons without histories of immune compromise. Directed referrals, earlier HIV treatment, and compensatory strategies aimed at counteracting the effects of low cognitive reserve, neurocognitive impairment, and psychiatric comorbidities on functional dependence in MA+/HIV+ individuals may be warranted.

The heritability of major normative domains of personality is well-established, with approximately half the proportion of variance attributed to genetic differences. In the current study, we examine the possibility of gene x environment interaction (GxE) for adult personality using the environmental context of intimate romantic relationship functioning. Personality and relationship satisfaction are significantly correlated phenotypically, but to date no research has examined how the genetic and environmental components of variance for personality differ as a function of romantic relationship satisfaction. Given the importance of personality for myriad outcomes from work productivity to psychopathology, it is vital to identify variables present in adulthood that may affect the etiology of personality. In the current study, quantitative models of GxE were used to determine whether the genetic and environmental influences on personality differ as a function of relationship satisfaction. We drew from a sample of now-adult twins followed longitudinally from adolescence through age 29. All participants completed the Multidimensional Personality Questionnaire (MPQ) and an abbreviated version of the Dyadic Adjustment Scale (DAS). Biometric moderation was found for eight of the eleven MPQ scales examined: Well-Being, Social Potency, Negative Emotionality, Alienation, Aggression, Constraint, Traditionalism, and Absorption. The pattern of findings differed, suggesting that the ways in which relationship quality moderates the etiology of personality may depend on the personality trait. PMID:26581694

Mucosal immunology of HIV infection.

2013-07-01

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 anti-bodies, 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. Furthermore, immune therapies specifically directed toward boosting specific aspects of the immune system may eventually lead to a cure for HIV-infected patients. © 2013 John Wiley & Sons A/S.

testing of material from genital lesions. In total, 22 strain types were identified. HIV-infected patients were diagnosed with nine different strains types and a difference by HIV status was not observed indicating that HIV-infected patients did not belong to separate sexual networks. In conclusion, concurrent HIV remains common in patients diagnosed with syphilis in Denmark, both in those diagnosed by serological testing and PCR testing. Although the rate of syphilis has stabilized in recent years, a spread to low-risk groups is of concern, especially due to the complex symptomatology of syphilis. However, given the efficient treatment options and the targeted screening of pregnant women and persons at higher risk of syphilis, control of the infection seems within reach. Avoiding new HIV infections is the major challenge and here cART may play a prominent role.

HIV has been reported to be cytotoxic in vitro and in lymph node infection models. Using a computational approach, we found that partial inhibition of transmissions of multiple virions per cell could lead to increased numbers of live infected cells. If the number of viral DNA copies remains above one after inhibition, then eliminating the surplus viral copies reduces cell death. Using a cell line, we observed increased numbers of live infected cells when infection was partially inhibited with the antiretroviral efavirenz or neutralizing antibody. We then used efavirenz at concentrations reported in lymph nodes to inhibit lymph node infection by partially resistant HIV mutants. We observed more live infected lymph node cells, but with fewer HIV DNA copies per cell, relative to no drug. Hence, counterintuitively, limited attenuation of HIV transmission per cell may increase live infected cell numbers in environments where the force of infection is high. PMID:29555018

The association of coronary heart disease (CHD) and human immunodeficiency virus (HIV) infection has been well recognized for many years. The etiology of the increased prevalence of CHD in HIV-infected populations is the result of complex interactions among the viral infection, host factors, traditional risk factors, and therapies for HIV. As the HIV population is living longer, largely attributable to combination antiretroviral therapy, there is concern about the effect of the rising prevalence of CHD on morbidity and mortality, as well its effect on health systems around the world. This review will highlight the epidemiological evidence linking HIV infection and CHD. It will also focus on our current understanding of the pathogenesis and factors associated with HIV infection and CHD. In addition, the review will highlight modes of presentation and management strategies for mitigating risk and treatment of HIV-positive patients presenting with CHD.

The problem of intestinal parasitic infection in human immunodeficiency virus (HIV)-infected people requires careful consideration in the developing world where poor nutrition is associated with poor hygiene and several coinfecting diseases. Studies have addressed this issue in Cameroon, especially in the low HIV prevalence area. The current study was conducted to determine the prevalence of intestinal parasitosis in people living with HIV (PLHIV) in Adamaoua and to identify associated risk factors. Stool and blood specimens from study participants were screened for intestinal parasites and anti-HIV antibodies, respectively. Of 235 participants, 68 (28.9%) were HIV positive, 38 of them on antiretroviral treatment (ART). The overall prevalence of intestinal parasites was 32.3%. Of 68 PLHIV, 32.3% (22/68) were infected with intestinal parasites, compared with 32.3% (54/167) of the HIV-negative patients. Univariate analysis showed no difference between the prevalence of intestinal parasites among PLHIV and HIV-negative patients ( P = 0.69). ART was not associated with the prevalence of intestinal parasites. Multivariate analysis showed that the quality of water and the personal hygiene were the major risk factors associated to intestinal parasitosis. The level of education was associated with HIV serostatus: the higher the level of education, the lower the risk of being infected with HIV ( P = 0.00). PLHIV and the general population should be screened routinely for intestinal parasites and treated if infected.

Recent studies suggest that older human immunodeficiency virus (HIV)-infected adults are at particular risk for HIV-associated neurocognitive disorders (HAND), including dementia. Deficits in attention/working memory are posited to play a central role in the development of HAND among older adults. The aim of the present study was to examine the possible protective benefits of spontaneous strategy use during a visual working memory task in 46 older and 42 younger adults infected with HIV. Results revealed a significant interaction between age and strategy use, with older adults who used a meta-cognitive strategy demonstrating superior working memory performance versus non-strategy users. This effect was not observed in the younger HIV-infected sample and was not better explained by possible confounding factors, such as education, comorbid medical conditions, or HIV disease severity. Within the older group, strategy use was associated with better executive functions and higher estimated verbal intelligence. Findings from this study suggest that working memory declines in older HIV-infected adults are moderated by the use of higher-level mnemonic strategies and may inform cognitive neurorehabilitation efforts to improve cognitive and everyday functioning outcomes in older persons living with HIV infection.

Objectives Antiretroviral (ARV) therapy has prolonged the life expectancy of HIV-infected persons, increasing their risk of age-associated diseases including atherosclerosis (AS). Decreased risk of AS has been associated with the prevention and control of hypertension (HTN). We conducted a cohort study of perimenopausal women and older men with or at-risk of HIV infection to identify risk factors for incident HTN. Methods Standardized interviews, physical examinations, and laboratory examinations were scheduled at 6-month intervals. Interview data included demographics, medical, family, sexual behavior, and drug use histories, and physical activity. Results There were 330 women and 329 men eligible persons; 27% and 35% of participants developed HTN during a median follow-up of 1080 and 1071 days, respectively. In gender-stratified analysis, adjusting for traditional HTN risk factors (age, race, BMI, smoking, diabetes, family history of HTN, alcohol dependence, physical activity, and high cholesterol), HIV infection was not associated with incident HTN in women or men [HR= 1.31, 95%CI (0.56, 3.06); HR = 1.67, 95%CI (0.75, 3.74), respectively]. Among HIV-infected women, although exposure to ARV's was not significantly associated with incident HTN [HR=0.72, 95%CI (0.26, 1.99)], CD4+ T-cell count was positively associated with incident HTN [HR=1.15 per 100 cells, 95%CI (1.03, 1.28)]. Among physically active HIV-infected men, exposure to ARV's was negatively associated with incident HTN [HR=0.15, 95%CI (0.03, 0.78)]. Conclusions HIV infection was not associated with incident HTN in older men or women. This study provides additional evidence supporting a causal relationship between immune function and incident HTN, which warrants further study. PMID:23294666

The outcome of CMV/HIV co-infection in infants treated early with combined antiretroviral therapy (cART) in resource-limited settings has not been described. We aimed to estimate the prevalence and identify factors associated with early CMV infection in HIV-infected and non-infected infants included in a study in Cameroon, and to compare HIV disease progression and survival after 1 year of early cART, following infants' CMV status. HIV-infected infants followed from birth or from HIV diagnosis before 7 months old and HIV-uninfected infants born to HIV-infected or uninfected mothers were tested for CMV at a median age of 4.0 months [Interquartile range (IQR): 3.4-4.9]. Multivariable logistic regression was performed to identify factors associated with CMV infection. Early cART was offered to HIV-infected infants: mortality, immunological and virological outcomes were assessed. Three hundred and sixty-nine infants were tested. The proportion of infants infected with CMV at baseline was significantly higher in HIV-infected than in HIV-uninfected groups (58.9% (86/146) vs 30.0% (67/223), p < 0.001). At baseline, median CMV viral load was higher in HIV-infected (3.7 log copies/ml [IQR; 3.1-4.3]) than in HIV-uninfected infants (2.8 log copies [IQR; 2.1-3.4], p < 0.001). cART was initiated in 90% of HIV-infected infants (132/146) at a median age of 4.0 months (IQR; 3.2-5.9); in this sub-group CMV infection was independently associated with being followed from the time of HIV diagnosis rather than from birth (aOR = 3.1, 95%CI [1.2-8.0]), born to a non-single mother (aOR = 3.4[1.4-8.1]), and breastfeeding (aOR = 7.3 [2.7-19.4]). HIV-infected infants were retested after a median of 7.1 months [4.8-9.5]: CMV was undetectable in 37 of the 61 (60.7%) initially CMV-infected cases and became detectable in 8 of the 38 (21.1%) initially CMV-negative cases. After 1 year of cART, the probability of death (0.185 vs 0.203; p = 0.75), the proportion of

Background Psychological adjustment and coping are central to human immunodeficiency virus (HIV) management. To improve HIV-infected patients’ ability to cope with stress, a variety of stress management interventions have been designed and evaluated. Purpose This paper provides a review and critique of the stress management literature, including a: (1) synthesis of core components of interventions for HIV-infected people, (2) summary of stress, coping, psychological, and health outcomes, and (3) methodological critique and guidance for future research. Methods We reviewed 21 stress management interventions designed for HIV-infected individuals that included both cognitive and behavioral skills training. Results Most studies noted positive changes in perceived stress, depression, anxiety, global psychological functioning, social support, and quality of life. However, results were mixed for coping and health status outcomes, and a majority of studies employed only brief follow-up periods, focused on HIV-infected MSM, and did not address HIV-specific stressors. Conclusions Stress management interventions for HIV-infected persons are a promising approach to facilitate positive adjustment. However, this literature is limited by measurement problems, research design features, a narrow focus on HIV-infected men who have sex with men, and feasibility concerns for intervention dissemination. Future stress management interventions should address these limitations and the unique psychosocial needs of HIV-infected patients using briefer, more cost-effective formats. PMID:18347902

ABSTRACT Human papillomavirus (HPV) infection is a frequent cause of malignant and non-malignant disease, in particular among persons with HIV. HPV serotype-specific anti L1 antibodies protect against HPV infection but little is known about prophylactic HPV vaccine-induced cell-mediated immunity against HPV in high-risk individuals. We recently showed that both HPV vaccines (Gardasil® and Cervarix®) induce solid, serological immune responses in HIV-infected persons. This study aimed to characterize HPV-specific CD4 T cells in HIV-infected HPV-vaccine recipients, T cell responses being critical for B cell activation and antibody-isotype switching. Thirty HIV-infected patients on long-term antiretroviral treatment (ART) received 3 doses of either Cervarix (n = 15) or Gardasil (n = 15) vaccine at month 0, 1.5 and 6. Cryopreserved peripheral blood mononuclear cells (PBMC) from baseline, 7 and 12 months were subjected to 24-hour stimulation with specific pools of HPV L1-peptides (HPV6, 11, 16, 18, 31 and 45) and HPV E6/E7-peptide pools (HPV6/11 and HPV16/18). Fluorescence-activated cell sorting with intracellular staining (IC-FACS) against CD4, CD154, IL-2, and IFNγ was performed. Frequencies (%) of HPV-antigen specific CD4+ T cells (CD154+/IL-2+ or CD154+/ IFNγ+) were determined. Both HPV-vaccines significantly and comparably enhanced cell-mediated vaccine L1 antigen-specific immunity in HIV-positive adults receiving ART therapy at month 7 and 12 after first vaccine dose. This suggests that the vaccines induce CD4 T cellular memory despite HIV-induced immune compromisation. PMID:29172992

Sexually transmitted infections (STIs) such as Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) can lead to adverse pregnancy and neonatal outcomes. The prevalence of STIs and its association with HIV mother-to-child transmission (MTCT) were evaluated in a substudy analysis from a randomized, multicenter clinical trial. Urine samples from HIV-infected pregnant women collected at the time of labor and delivery were tested using polymerase chain reaction testing for the detection of CT and NG (Xpert CT/NG; Cepheid, Sunnyvale, CA). Infant HIV infection was determined by HIV DNA polymerase chain reaction at 3 months. Of the 1373 urine specimens, 249 (18.1%) were positive for CT and 63 (4.6%) for NG; 35 (2.5%) had both CT and NG detected. Among 117 cases of HIV MTCT (8.5% transmission), the lowest transmission rate occurred among infants born to CT- and NG-uninfected mothers (8.1%) as compared with those infected with only CT (10.7%) and both CT and NG (14.3%; P = 0.04). Infants born to CT-infected mothers had almost a 1.5-fold increased risk for HIV acquisition (odds ratio, 1.47; 95% confidence interval, 0.9-2.3; P = 0.09). This cohort of HIV-infected pregnant women is at high risk for infection with CT and NG. Analysis suggests that STIs may predispose to an increased HIV MTCT risk in this high-risk cohort of HIV-infected women.

Background. HIV-infected adolescents may be at higher risk for high-grade cervical lesions than HIV-uninfected adolescents. The purpose of this study was to compare the prevalence of high-risk HPV (HR-HPV) infections and Pap smear abnormalities between these two groups. Methods. In this cross-sectional study, we compared the HPV DNA and Pap smear results between 35 HIV-infected and 50 HIV-uninfected adolescents in order to determine the prevalence of HR-HPV genotypes and cervical cytological abnormalities. Comparisons were made using Pearson χ 2 and independent-samples t-tests analyses, and associations between demographic and behavioral characteristics and HPV infections were examined. Results. HIV-infected participants were more likely to be infected with any HPV (88.6% versus 48.0%; P < 0.001) and with at least one HR-HPV (60.0% versus 24.0%; P = 0.001), and to have multiple concurrent HPV infections (68.6% versus 22.0%; P < 0.001). HPV 16 and 18 were relatively underrepresented among HR-HPV infections. Abnormal Pap test results were more common among HIV-infected participants (28.8% versus 12.0%; P = 0.054). A history of smoking was associated with HR-HPV infection. Conclusions. HIV-infected adolescents have an increased risk of infection with HR-HPV and of Pap test abnormalities. The majority of HR-HPV infections among our participants would not be prevented by the currently available vaccinations against HPV. PMID:25389377

Tuberculosis (TB) and human immunodeficiency virus (HIV) infection are leading causes of disease and death in Vietnam, but TB/HIV disease trends and the profile of co-infected patients are poorly described. We examined national TB and HIV notification data to provide a geographic overview and describe relevant disease trends within Vietnam. We also compared the demographic and clinical profiles of TB patients with and without HIV infection. During the past 10 years (2005-2014) cumulative HIV case numbers and deaths increased to 298,151 and 71,332 respectively, but access to antiretroviral therapy (ART) improved and new infections and deaths declined. From 2011-2014 routine HIV testing of TB patients increased from 58.9% to 72.5% and of all TB patients diagnosed with HIV in 2014, 2,803 (72.4%) received ART. The number of multidrug resistant (MDR)-TB cases enrolled for treatment increased almost 3-fold (578 to 1,532) from 2011-2014. The rate of HIV co-infection in MDR and non-MDR TB cases (51/1,532; 3.3% vs 3,774/100,555; 3.8%; OR 0.77, 95% CI 0.7-1.2) was similar in 2014. The care of TB/HIV co-infected patients have shown sustained improvement in Vietnam. Rising numbers of MDR-TB cases is a concern, but this is not "driven" by HIV co-infection.

To validate the Medical Outcomes Study HIV Health Survey (MOS-HIV) quality of life instrument for its application in clinical research in Mexico. The data for this study were collected between April, 2002, and February, 2004. An expert committee combined two Spanish-language translations of the MOS-HIV questionnaire. The new questionnaire's feasibility was assessed in a group of 32 HIV-infected persons by measuring how long they took to complete the questionnaire and the numbers of items they left unanswered. The questionnaire was then applied to a group of 120 HIV-positive patients and to a control group of 102 HIV-negative individuals. The following questionnaire characteristics were evaluated: (1) internal reliability (Cronbach alpha coefficient), (2) discriminant validity (the receiver operating characteristic (ROC) curves derived from the scores of the two groups), and (3) convergent validity (the Spearman correlation coefficients for the scores of the HIV-positive patients on the 11 MOS-HIV dimensions and their scores on the analog visual scale of the European Quality of Life 5-Dimensional format (EQ-5D) questionnaire, a list of symptoms, the viral load, and the CD4 cell count). The mean response time with the questionnaire was 10 minutes and 22 seconds, and the mean number of unanswered items was 0.62. With each of the 11 dimensions of the questionnaire, the Cronbach alpha coefficient was at least 0.75. The mean scores obtained by the two groups were different for 9 of the 11 dimensions, and the 95% confidence intervals of the areas under the ROC curves did not include the value of 0.5 for 8 of the dimensions. The absolute value of the Spearman correlation coefficient was less than 0.3 for the CD4 cell count and for the viral load, and it was greater than 0.3 for each dimension and the scores on the list of symptoms and on the analog visual scale of the EQ-5D questionnaire. The MOS-HIV measure is valid for use in clinical research among HIV-infected persons

Mortality in young people with perinatally acquired HIV infection (PHIV) following transfer to adult care has not been characterized in the UK. We conducted a multicentre audit to establish the number of deaths and associated factors. Fourteen adult clinics caring for infected young people reported deaths to 30 September 2011 on a proforma. Deaths were matched to the Collaborative HIV Paediatric Study, a clinical database of HIV-infected children in the UK/Ireland, to describe clinical characteristics in paediatric care of those who died post-transition. Eleven deaths were reported from 14 clinics which cared for 248 adults with PHIV. For the 11 deaths, the median age at transfer to adult care was 17 years (range 15-21 years), and at death was 21 years (range 17-24 years). Causes of death were suicide (two patients), advanced HIV disease (seven patients) and bronchiectasis (one patient), with one cause missing. At death, the median CD4 count was 27 cells/μL (range 0-630 cells/μL); five patients were on antiretroviral therapy (ART) but only two had a viral load < 50 HIV-1 RNA copies/mL. Nine had poor adherence when in paediatric care, continuing into adult care despite multidisciplinary support. Eight had ART resistance, although all had potentially suppressive regimens available. Nine had mental health diagnoses. Our findings highlight the complex medical and psychosocial issues faced by some adults with PHIV, with nine of the 11 deaths in our study being associated with poor adherence and advanced HIV disease. Novel adherence interventions and mental health support are required for this vulnerable cohort. © 2013 British HIV Association.

Sexual partner concurrency is common among MSM and may increase the probability of HIV transmission during recent (acute or early) infection. We examined the relationship between concurrency and HIV transmission network characteristics (proxies for HIV transmission) among MSM with recent HIV infection. Observational study integrating behavioral, clinical, and molecular epidemiology. We inferred a partial HIV transmission network using 986 HIV-1 pol sequences obtained from HIV-infected individuals in San Diego, California (1996-2015). We further analyzed data from 285 recently HIV-infected MSM in the network who provided information on up to three sexual partners in the past 3 months, including the timing of intercourse with each partner. Concurrency was defined as sexual partners overlapping in time. Logistic and negative binomial regressions were used to investigate the link between concurrency and HIV transmission network characteristics (i.e. clustering and degree or number of connections to others in the network) among these MSM. Of recently HIV-infected MSM (n = 285), 54% reported concurrent partnerships and 54% were connected by at least one putative transmission link to others (i.e. clustered) in the network (median degree = 1.0; interquartile range: 0.0-3.0). Concurrency was positively associated with HIV transmission network clustering (adjusted odds ratio = 1.83, 95% confidence interval: 1.08, 3.10) and degree (adjusted incidence rate ratio = 1.48, 95% confidence interval: 1.02, 2.15). Our findings provide empirical evidence consistent with the hypothesis that concurrency facilitates HIV transmission during recent infection. Interventions to mitigate the impact of concurrency on HIV transmission may help curb the HIV epidemic among MSM.

HIV/1 group P (HIV-1/P) is the last HIV/1 group discovered and, to date, constitutes only two strains. To obtain new insight into this divergent group, we screened for new infections by developing specific tools, and analysed phenotypic and genotypic properties of the prototypic strain RBF168. In addition, the follow-up of the unique infected patient monitored so far has raised the knowledge of the natural history of this infection and its therapeutic management. We developed an HIV-1/P specific seromolecular strategy and screened over 29 498 specimen samples. Infectivity and evolution of the gag-30 position, considered as marker of adaptation to human, were explored by successive passages of RBF168 strain onto human peripheral blood mononuclear cells. Natural history and immunovirological responses to combined antiretroviral therapy (cART) were analysed based on CD4 cells and plasmatic viral load evolution. No new infection was detected. Infectivity of RBF168 was found lower, relative to other main HIV groups and the conservative methionine found in the gag-30 position revealed a lack of adaptation to human. The follow-up of the patient during the 5-year ART-free period, showed a relative stability of CD4 cell count with a mean of 326 cells/μl. Initiation of cART led to rapid RNA undetectability with a significant increase of CD4 cells, reaching 687 cells/μl after 8 years. Our results showed that HIV-1/P strains remain extremely rare and could be less adapted and pathogenic than other HIV strains. These data lead to the hypothesis that HIV-1/P infection could evolve towards, or even already corresponds to, a dead-end infection.

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

The molecular mechanism of human resistance to HIV-1 infection in persistently infected individuals--a review, hypothesis and implications.

PubMed

Becker, Yechiel

Resistance to HIV-1 infection in Europeans is associated with a mutation in the gene that codes for the CCR5 protein that is present in Th2 cells and serves as a coreceptor for HIV-1 R5 strain. A deletion of 32 amino acids from the cytokine receptor prevents infection. This mutation prevails in Europeans and is absent in Africans. However, duplication of a gene that codes for a chemokine that binds to the CCR5 was discovered in Africans (mean gene copy 6 while in non-Africans the mean gene copy is 3). Higher expression of these genes protects T cells against HIV-1 infection in vitro. It should be noted that resistance to HIV-1 R5 variant does not protect against HIV-1 R4 variant. It was reported that a minority of highly HIV-1 exposed African professional sex workers (APSW) were resistant to the virus infection during a 10 years period. Recently, the analysis of the cytokines in the serum of the persistently infected seronegative women revealed that the latter hypo-expresses the cytokine IL-4. Since the molecular events during HIV-1 infection are associated with a marked increase in the levels of IL-4 and IgE in the sera of the infected individuals, it suggests that AIDS is an allergy. Thus, a very low level of IL-4 production may abrogate the virus infection. Studies on the human IL-4 gene revealed that together with the IL-4 mRNA a spliced variant with a deletion of exon 2 is synthesized. The latter is a natural antagonist of IL-4 and when expressed in an individual at a level higher than IL-4, the person will resist a microbial infection (e.g. Mycobacterium tuberculosis) or asthma. The present hypothesis suggests that the HIV-1 resistant APSWs produce more IL-4 delta 2 molecules than IL-4 molecules. The binding of IL-4 delta 2 to IL-4 receptors on T and B cells prevents their functions and the infection by HIV-1. The implications of these studies are that treatment of HIV-1 infected people with drugs that will block the IL-4 receptors will stop HIV-1 infections

Objective To longitudinally characterize non-invasive markers of liver disease in HIV-infected youth. Design HIV infection, without viral hepatitis co-infection, may contribute to liver disease. Non-invasive markers of liver disease [FIB-4 (Fibrosis-4) and APRI (aspartate aminotransferase-to-platelet ratio index)] have been evaluated in adults with concomitant HIV and hepatitis C, but are less studied in children. Methods In prospective cohorts of HIV-infected and HIV-uninfected youth, we used linear regression models to compare log-transformed FIB-4 and APRI measures by HIV status based on a single visit at ages 15–20 years. We also longitudinally modeled trends in these measures in HIV-infected youth with ≥2 visits to compare those with behavioral vs perinatal HIV infection (PHIV) using mixed effect linear regression, adjusting for age, gender, body mass index, and race/ethnicity. Results Of 1785 participants, 41% were male, 57% black non-Hispanic and 27% Hispanic. More HIV-infected than uninfected youth had an APRI score >0.5 (13% vs 3%, p<0.001). Among 1307 HIV-infected participants with longitudinal measures, FIB-4 scores increased 6% per year (p<0.001) among all HIV-infected youth, whereas APRI scores increased 2% per year (p=0.007) only among PHIV youth. The incidence rates (95% CI) of progression of APRI to >0.5 and >1.5 were 7.5 (6.5–8.7) and 1.4 (1.0–1.9) cases per 100 person-years of follow up, respectively. The incidence of progression of FIB-4 to >1.5 and >3.25 were 1.6 (1.2–2.2) and 0.3 (0.2–0.6) cases per 100 person-years, respectively. Conclusions APRI and FIB-4 scores were higher among HIV-infected youth. Progression to scores suggesting subclinical fibrosis or worse was common. PMID:26959353

Introduction : Pre-exposure prophylaxis (PrEP) can provide high protection against HIV infection and is a recommended intervention for HIV-negative persons with substantial HIV risk, such as individuals with a partner living with HIV.  Demonstration projects of PrEP have been conducted in diverse settings worldwide to illustrate practical examples of how PrEP can be delivered.  Methods : We evaluated delivery of PrEP for HIV-negative partners within heterosexual HIV serodiscordant couples in an open-label demonstration project in East Africa.  The delivery model integrated PrEP into HIV treatment services, prioritizing PrEP for HIV-negative partners within serodiscordant couples prior to and during the first 6 months after the partner living with HIV initiated antiretroviral therapy (ART).  We measured adherence to PrEP through medication event monitoring system (MEMS) bottle caps and quantification of tenofovir in plasma among a random sample of participants. We estimated HIV infections prevented using a counterfactual cohort simulated from the placebo arm of a previous PrEP clinical trial. Results : We enrolled 1,010 HIV serodiscordant couples that were naïve to ART and PrEP.  Ninety-seven percent (97%) of HIV-negative partners initiated PrEP, and when PrEP was dispensed, objective measures suggest high adherence: 71% of HIV-negative participants took ≥80% of expected doses, as recorded via MEMS, and 81% of plasma samples had tenofovir detected.  A total of 4 incident HIV infections were observed (incidence rate=0.24 per 100 person-years), a 95% reduction (95% CI 86-98%, p<0.0001) in HIV incidence, relative to estimated HIV incidence for the population in the absence of PrEP integrated into HIV treatment services.   Conclusions : PrEP uptake and adherence were high and incident HIV was rare in this PrEP demonstration project for African HIV-negative individuals whose partners were known to be living with HIV.  Delivery of PrEP to HIV-negative partners

HIV infection has been modifying both the epidemiology and outcome of parasite infections. Hence, this study was undertaken to determine the prevalence of Cryptosporidium and other intestinal parasite infections among HIV positives with and without Antiretroviral Treatment(ART) and its association with CD4+ T-cell count. A cross-sectional study was conducted at Fitche hospital focusing on HIV positives who came to hospital for follow-ups. A total of 378 HIV positive persons with and without ART participated in the study. Data on socio-demographic factors and diarrhoea status were obtained by interviewing all 214 with ART and 164 without ART. Stool samples were collected from all patients and examined for intestinal parasites using direct, formol-ether and modified acid-fast staining techniques. The prevalence of intestinal parasite infections in this study was significantly higher among HIV positive persons not on ART. Specifically, the rate of infection with Cryptosporidium species, Blastocystis spp., Giardia lamblia, and Entamoeba histolytica/E. dispar were higher, particularly in those with CD4+ T-cell counts less than 200 cells/µL. Fifty seven percent of the study participants were on ART. Out of these 164/378 (43%) of the non-ART study participants were infected with at least one intestinal parasite species. Significant association was observed between lower CD4+ T-cell count (<200 cells/µL) and the prevalence of Cryptosporidium spp. and Blastocystis spp. The two parasites were significantly more prevalent in HIV positive non-ART patients. HIV infection increased the risk of having Cryptosporidium and other intestinal parasites and diarrhoea. Therefore, raising HIV positive's immune status and screening for intestinal parasites is important. This study showed that patients who are taking ART had a lower prevalence of diarrhoea causing parasites and Cryptosporidium suggesting that ART through improvement of immune status of the patients may have contributed

 Trends in CD4 + T-cell count at human immunodeficiency virus (HIV) infection diagnosis and antiretroviral therapy (ART) initiation can be characterized using laboratory tests from surveillance.  We used CD4 + T-cell counts and viral loads from New York City for persons who received a diagnosis of HIV infection during 2006-2012.  From 2006 to 2012, the median CD4 + T-cell count increased from 325 to 379 cells/µL at diagnosis and from 178 to 360 cells/μL at ART initiation. CD4 + T-cell counts were consistently lower in women, blacks, Hispanics, persons who inject drugs, and heterosexuals.  Increases in CD4 + T-cell count at diagnosis and ART initiation suggest that the time from HIV infection to ART initiation has been reduced substantially in New York City. © The Author 2016.

HIV infection in children.

PubMed

Canosa, C A

Various studies have reported rates of human immunodeficiency virus (HIV) transmission from mother to child of 13-40%. Vertical transmission occurs in utero, during delivery, or, in a small number of cases, through breast milk. Whether mothers at various stages of HIV infection experience different rates of transmission remains unknown. Maternal antibodies cross the placenta and are present from birth up to 18 months of age. The offspring of HIV-positive mothers tend to be low birthweight, under 37 weeks' gestation, and at high risk of perinatal mortality. It is likely, however, that this profile is indicative of the low socioeconomic status of most women with HIV rather than a result of infection. Also emerging is a psychosocial profile of the HIV child. These children are isolated, neglected, battered, frequently abandoned, and exhibit various degrees of mental retardation. Also common are delayed psychomotor development, loss of developmental milestones, limited attention span, poor language development, and abnormal reflexes. These features result from the interaction of low socioeconomic status, a lack of psychosocial stimulation, nutritional deficiencies, and central nervous system infections. Since HIV-infected children tend to be the offspring of drug addicts, bisexuals, and prostitutes, they are not awarded the same compassion as children afflicted with other terminal illnesses. Moreover, these children are generally neglected by groups formed to provide support to AIDS patients. Thus, it is up to the general public, the mass media, and the health care system to advocate for the needs of these neglected children.

Background Isolated antibody to hepatitis B core antigen (anti-HBc) is a common serologic finding in persons infected with human immunodeficiency virus (HIV), but the outcome and clinical significance are uncertain. Methods We performed repeated hepatitis B virus (HBV) serologic tests on women who participated in the Women’s Interagency HIV Study and who had isolated anti-HBc at study entry. Results Repeated serologic tests were performed for 322 women (282 HIV-infected and 40 HIV-uninfected) at a median of 7.5 years after study entry. Seventy-one percent of women retained isolated anti-HBc serologic status, 20% acquired antibody to hepatitis B surface antigen (anti-HBs), and 2% acquired hepatitis B surface antigen (HBsAg). In unadjusted analysis, increasing age, injection drug use, and hepatitis C viremia were negatively associated with acquisition of anti-HBs. For HIV-infected women, predictors of acquisition of anti-HBs were an increase in CD4 cell count and the use of highly active antiretroviral therapy (HAART). Receipt of drugs with activity against HBV and self-reported HBV vaccination did not predict anti-HBs acquisition. In the multivariable regression model, HAART use remained a significant predictor of anti-HBs acquisition, whereas women with hepatitis C viremia were more likely to retain isolated anti-HBc serologic status. Conclusions Isolated anti-HBc status remained stable over time for the majority of women, especially women with chronic hepatitis C virus infection. Development of anti-HBs was predicted by HAART use and an increase in CD4 cell count. We conclude that a proportion of HIV-infected women with isolated anti-HBc have prior natural HBV infection with anti-HBs that is at an undetectable level because of immune dysfunction. Isolated anti-HBc in the presence of chronic hepatitis C virus infection may be attributable to a different phenomenon, such as dysfunctional antibody production. PMID:19480573

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.

This investigation studied the influence of sex, college major, and attributed responsibility on college students' empathic responding towards persons infected with HIV. We hypothesized that (1) women would score higher on empathy than men; (2) nursing and psychology majors would score higher on empathy than business and computer science majors; and (3) participants would score higher on empathy towards a target who contracted HIV through blood transfusion (presented as a Nonresponsible target) rather than through unprotected sex (presented as a Responsible target). Two hundred and fifty-eight undergraduate students (110 male, 148 female) attending a large urban university in the northeast filled out an anonymous demographic questionnaire, the Interpersonal Reactivity Index of Davis (1983), and an Empathy Reaction Scale that was developed by the authors. Results indicated a higher mean Empathy Reaction score from nursing and psychology students as compared to business and computer science students. There was no difference in Empathy Reaction scores between men and women. A higher Empathy Reaction score was found among participants who had read a diary from the target portrayed as Nonresponsible, as opposed to those who read a diary from the target portrayed as Responsible.

Antiretroviral preexposure prophylaxis has been shown to reduce the risk of human immunodeficiency virus type 1 (HIV-1) infection in some studies, but conflicting results have been reported among studies, probably due to challenges of adherence to a daily regimen. We conducted a double-blind, randomized trial of antiretroviral therapy for preexposure HIV-1 prophylaxis among men who have unprotected anal sex with men. Participants were randomly assigned to take a combination of tenofovir disoproxil fumarate (TDF) and emtricitabine (FTC) or placebo before and after sexual activity. All participants received risk-reduction counseling and condoms and were regularly tested for HIV-1 and HIV-2 and other sexually transmitted infections. Of the 414 participants who underwent randomization, 400 who did not have HIV infection were enrolled (199 in the TDF-FTC group and 201 in the placebo group). All participants were followed for a median of 9.3 months (interquartile range, 4.9 to 20.6). A total of 16 HIV-1 infections occurred during follow-up, 2 in the TDF-FTC group (incidence, 0.91 per 100 person-years) and 14 in the placebo group (incidence, 6.60 per 100 person-years), a relative reduction in the TDF-FTC group of 86% (95% confidence interval, 40 to 98; P=0.002). Participants took a median of 15 pills of TDF-FTC or placebo per month (P=0.57). The rates of serious adverse events were similar in the two study groups. In the TDF-FTC group, as compared with the placebo group, there were higher rates of gastrointestinal adverse events (14% vs. 5%, P=0.002) and renal adverse events (18% vs. 10%, P=0.03). The use of TDF-FTC before and after sexual activity provided protection against HIV-1 infection in men who have sex with men. The treatment was associated with increased rates of gastrointestinal and renal adverse events.

Perinatal transmission and reproductive decisions of HIV-infected women can be categorized in statistical and epidemiological terms. These reports and figures, however, do little to fully explain the complexities of human relationships, life experiences, personal and cultural influences, and situational and environmental variables that impact on the HIV-infected woman regarding reproductive decision-making. It is only with genuine attempts to understand the woman's perspective and the dynamic and unique variables that influence reproductive decision-making, as well as maintaining a non-judgmental and culturally sensitive perspective, can we hope to assist women, and society as a whole, in coming to terms with the complexities of HIV and reproductive decision-making. Further study is needed to identify factors that influence reproductive decision-making in HIV-infected women. The determinants of contraceptive use regarding demographic factors, barriers to contraceptive use, and factors that contribute to successful contraceptive use in this population must be understood if efforts to reduce the number of unplanned pregnancies are to be successful. More conclusive data are needed on the safety and efficacy of oral contraceptives in HIV-infected women as well as data that describe the effects of longer acting hormonal contraceptives such as levonorgestrel implants (Norplant; Wyeth-Ayerst, Philadelphia, PA) and injectable medroxyprogesterone acetate (Depo Provera; Upjohn Company, Kalamazoo, MI). More research is needed to determine the effects of patient education and counseling and closer follow-up on effective long-term contraception in HIV-infected women.

Abstract Purpose: Among black transgender women (transwomen) at high risk of HIV acquisition or already living with HIV/AIDS, the study examined whether medical or socially based gender affirming factors may contribute differentially to selected measures of resiliency, perceived stress, and a scale measure of mental health outcomes. This question has implications for clinical care and counseling of this population. Methods: Seventy-seven black transwomen were recruited to participate in a private, face-to-face structured interview. Two index measures of gender affirmation (GA) were constructed from the data. One comprised medical aspects only and the other comprised social aspects of GA. Assessed outcomes were personal competence and acceptance of self and life (resiliency), perceived stress and recent anxiety, depression, and suicide ideation (mental health). Associations between GA variables and outcomes were first assessed using bivariate level correlations. Significant bivariate associations were then tested in multivariable regression models adjusting for age and HIV status. Results: Mean age of the sample was 34.5 years. More than one-half of the sample (62.3%) indicated being HIV-infected. None of the bivariate or multivariable associations pertaining to GA medical factors were significant. Conversely, the social GA factors were significant and protective with all four outcomes. In the presence of age and HIV status, greater social GA was significantly associated with greater personal competence, acceptance of self and life, and positive mental health outcome. HIV status had an independent effect on personal competence, acceptance of self and life, with HIV-positive transwomen scoring higher on both measures. Conclusion: Among black transwomen at high risk of HIV acquisition or already HIV-infected, study findings suggest the possibility that socially based GA may play a prominent role in strengthening the resiliency and mental health of black transwomen
