Full Text Available The prevalence and factors associated with overweight/obesity among human immunodeficiency virus (HIV-infected persons are unknown.We evaluated prospective data from a U.S. Military HIV Natural History Study (1985-2004 consisting of early diagnosed patients. Statistics included multivariate linear regression and longitudinal linear mixed effects models.Of 1682 patients, 2% were underweight, 37% were overweight, and 9% were obese at HIV diagnosis. Multivariate predictors of a higher body mass index (BMI at diagnosis included more recent year of HIV diagnosis, older age, African American race, and earlier HIV stage (all p<0.05. The majority of patients (62% gained weight during HIV infection. Multivariate factors associated with a greater increase in BMI during HIV infection included more recent year of diagnosis, lower BMI at diagnosis, higher CD4 count, lower HIV RNA level, lack of AIDS diagnosis, and longer HIV duration (all p<0.05. Nucleoside agents were associated with less weight gain; other drug classes had no significant impact on weight change in the HAART era.HIV-infected patients are increasingly overweight/obese at diagnosis and during HIV infection. Weight gain appears to reflect improved health status and mirror trends in the general population. Weight management programs may be important components of HIV care.

BACKGROUND: Increased incidence of cardiovascular diseases (CVD) in both HIV infection and type 2 diabetes (T2D) compared to the general population has been described. Little is known about the combined effect of HIV infection and T2D on inflammation and endothelial function, both of which may...... contribute to elevated risk of CVD. METHODS: Cross-sectional study including 50 HIV-infected persons on combination anti-retroviral therapy (cART), with HIV RNA 2D (HIV + T2D+), n = 25 without T2D (HIV + T2D-)) and 50 uninfected persons (n = 22 with T2D (HIV-T2D+) and n = 28...... without T2D (HIV-T2D-)). Groups were matched on age and sex. High sensitive C-reactive protein (hsCRP) was used to determine inflammation (cut-off 3 mg/L). The marker of endothelial dysfunction asymmetric dimethylarginine (ADMA) was measured using high performance liquid chromatography. Trimethylamine...

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

Prolonged pathogen shedding and increased duration of illness associated with infections in immunosuppressed individuals put close human immunodeficiency virus (HIV)-negative contacts of HIV-infected persons at increased risk of exposure to infectious pathogens. We calculated incidence and longitudinal prevalence (number of days per year) of influenzalike illness (ILI), diarrhea, and nonspecific febrile illness during 2008 from a population-based surveillance program in the urban slum of Kibera (Kenya) that included 1830 HIV-negative household contacts of HIV-infected individuals and 13 677 individuals living in exclusively HIV-negative households. For individuals ≥5 years old, incidence was significantly increased for ILI (risk ratio [RR], 1.47; P 5 years old. Targeted interventions are needed, including ensuring that HIV-infected persons are receiving appropriate care and treatment.

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

The era of modern HIV therapeutics is well underway. The cancer and infectious disease epidemiology of HIV disease has markedly altered as populations are availed to the benefits of antiretroviral therapy (ARV). The types of cancers occurring among those with HIV infection has broadened but the case burden in absolute numbers is very low relative to the background population. There are fewer incident cases of the AIDS-defining cancers (aggressive B-cell lymphomas, Kaposi's sarcoma, and cervical cancer). There is an increased risk for certain non-AIDS-defining cancers, but these occur somewhat sporadically relative to clinical trial enrollment. The changing epidemiology of cancer in HIV poses challenges as well as opportunities for participation of persons with HIV in cancer therapy clinical trials. There are excellent examples of cancer trials that inform cancer therapy for patients with HIV infection. Examples include those from HIV-specific trials and from trials mainly focused on the background population that included patients with HIV infection. Interpretation of clinical trials to guide therapy for those with HIV infection and cancer largely depends on data that does not include HIV-infected patients. The ability to extend clinical trial findings to populations not included in clinical trials remains problematic for a variety of populations, including those with HIV or AIDS. Careful prioritization of studies designed to bridge this gap is needed. However, there are published studies that serve as excellent examples bridging these gaps and the portfolio of cancer therapy trials underway will inform HIV and cancer better than at any time in the past.
Background Safety of vaccines remains a cornerstone of building public trust on the use of these cost-effective and life-saving public health interventions. In some settings, particularly Sub-Saharan Africa, there is a high prevalence of HIV infection and a high burden of vaccine-preventable diseases. There is evidence suggesting that the immunity induced by some commonly used vaccines is not durable in HIV-infected persons, and therefore, repeated vaccination may be considered to ensure optimal vaccine-induced immunity in this population. However, some vaccines, particularly the live vaccines, may be unsafe in HIV-infected persons. There is lack of evidence on the safety profile of commonly used vaccines among HIV-infected persons. We are therefore conducting a systematic review to assess the safety profile of routine vaccines administered to HIV-infected persons. Methods/Design We will select studies conducted in any setting where licensed and effective vaccines were administered to HIV-infected persons. We will search for eligible studies in PubMed, Web of Science, Cochrane Central Register of Controlled Trials (CENTRAL), Scopus, Africa-Wide, PDQ-Evidence and CINAHL as well as reference lists of relevant publications. We will screen search outputs, select studies and extract data in duplicate, resolving discrepancies by discussion and consensus. Discussion Globally, immunisation is a major public health strategy to mitigate morbidity and mortality caused by various infectious disease-causing agents. In general, there are efforts to increase vaccination coverage worldwide, and for these efforts to be successful, safety of the vaccines is paramount, even among people living with HIV, who in some situations may require repeated vaccination. Results from this systematic review will be discussed in the context of the safety of routine vaccines among HIV-infected persons. From the safety perspective, we will also discuss whether repeat vaccination strategies may be

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.

Full Text Available Lower muscle density on computed tomography (CT provides a measure of fatty infiltration of muscle, an aspect of muscle quality that has been associated with metabolic abnormalities, weakness, decreased mobility, and increased fracture risk in older adults. We assessed the cross-sectional relationship between HIV serostatus, age, thigh muscle attenuation, and thigh muscle cross-sectional area (CSA.Mean CT-quantified Hounsfield units (HU of the thigh muscle bundle and CSA were evaluated in 368 HIV-infected and 145 HIV-uninfected men enrolled in the Multicenter AIDS Cohort Study (MACS Cardiovascular Substudy using multivariable linear regression. Models all were adjusted for HIV serostatus, age, race, and body mass index (BMI; each model was further adjusted for covariates that differed by HIV serostatus, including insulin resistance, hepatitis C, malignancy, smoking, alcohol use, and self-reported limitation in physical activity.HIV-infected men had greater thigh muscle CSA (p<0.001 but lower muscle density (p<0.001 compared to HIV-uninfected men. Muscle density remained lower in HIV-infected men (p = 0.001 when abdominal visceral adiposity, and thigh subcutaneous adipose tissue area were substituted for BMI in a multivariable model. Muscle density decreased by 0.16 HU per year (p<0.001 of increasing age among the HIV-infected men, but not in the HIV-uninfected men (HIV x age interaction -0.20 HU; p = 0.002.HIV-infected men had lower thigh muscle density compared to HIV-uninfected men, and a more pronounced decline with increasing age, indicative of greater fatty infiltration. These findings suggest that lower muscle quality among HIV-infected persons may be a risk factor for impairments in physical function with aging.

Crofelemer is a first-in-class antidiarrheal agent that is United States Food and Drug Administration approved for noninfectious diarrhea in persons with HIV on antiretroviral therapy. Crofelemer is derived from the blood-red sap of Croton lechleri, a South American plant whose latex is associated with various healing attributes. In fact, it has a unique effect on chloride channels in the gastrointestinal lumen, and leads to decreased efflux of sodium molecules and water, thereby decreasing the frequency of stools. Crofelemer – a plant-based compound, discovered and investigated as the result of the increased prevalence of ethnobotany – is a novel and effective agent with a good safety profile. It could potentially improve the quality of life for HIV-infected patients and hopefully, in turn, will improve antiretroviral therapy compliance.Keywords: chloride channels, secretory diarrhea, botanical, sangre de grado, intra-luminal

Full Text Available Untreated HIV may increase the risk of cardiovascular events. Our preliminary in vitro and in vivo research suggests that pentoxifylline (PTX reduces vascular inflammation and improves endothelial function in HIV-infected persons not requiring antiretroviral therapy.We performed a randomized, placebo-controlled trial of PTX 400 mg orally thrice daily for 8 weeks in 26 participants. The primary endpoint was change in flow-mediated dilation (FMD of the brachial artery after 8 weeks. Nitroglycerin-mediated dilation (NTGMD and circulating markers of inflammation, cellular immune activation, coagulation, and metabolism were also assessed.The difference in mean absolute change (SD in FMD after 8 weeks between the placebo [-1.06 (1.45%] and PTX [-1.93 (3.03%] groups was not significant (P = 0.44. No differences in NTGMD were observed. The only significant between-group difference in the changes in biomarkers from baseline to week 8 was in soluble tumor necrosis factor receptor-1 (sTNFRI [-83.2 pg/mL in the placebo group vs. +65.9 pg/mL in the PTX group; P = 0.03]. PTX was generally well-tolerated.PTX did not improve endothelial function and unexpectedly increased the inflammatory biomarker sTNFRI in HIV-infected participants not requiring antiretroviral therapy. Additional interventional research is needed to reduce inflammation and cardiovascular risk in this population.ClinicalTrials.gov NCT00796822.

Full Text Available Abstract Background Opportunistic oral infections can be found in over 80% of HIV + patients, often causing debilitating lesions that also contribute to deterioration in nutritional health. Although appreciation for the role that the microbiota is likely to play in the initiation and/or enhancement of oral infections has grown considerably in recent years, little is known about the impact of HIV infection on host-microbe interactions within the oral cavity. In the current study, we characterize modulations in the bacterial composition of the lingual microbiome in patients with treated and untreated HIV infection. Bacterial species profiles were elucidated by microarray assay and compared between untreated HIV infected patients, HIV infected patients receiving antiretroviral therapy, and healthy HIV negative controls. The relationship between clinical parameters (viral burden and CD4+ T cell depletion and the loss or gain of bacterial species was evaluated in each HIV patient group. Results In untreated HIV infection, elevated viremia was associated with significantly higher proportions of potentially pathogenic Veillonella, Prevotella, Megasphaera, and Campylobacter species in the lingual microbiome than observed in healthy controls. The upsurge in the prevalence of potential pathogens was juxtaposed by diminished representation of commensal Streptococcus and Veillonella species. Colonization of Neisseria flavescens was lower in the lingual microbiome of HIV infected patients receiving antiretroviral therapy than in uninfected controls. Conclusions Our findings provide novel insights into the potential impact of HIV infection and antiretroviral therapy on the community structure of the oral microbiome, and implicate potential mechanisms that may increase the capacity of non-commensal species to gain a stronger foothold.

Physical function impairments are seen among aging, HIV-infected persons on effective antiretroviral therapy (ART). The impact of physical function impairments on health-related quality of life (QoL) during ART is unknown. This was a cross-sectional study including 359 HIV-infected patients, aged 45-65 years, on ART for more than 6 months. Patients completed the SF-36 QoL questionnaire, 400-m walk, 5-time chair rise, and grip strength. HIV-associated mortality risk was calculated using the Veterans Aging Cohort Study (VACS) Index. Physical function, physical activity (> 500 versus ≤ 500 kcal/week), and VACS scores were used to estimate QoL in multivariable linear regression. For every 1 m/s increase in gait speed, we saw an estimated 11.8 [95% confidence interval (CI) 8.4, 15.2] point increase in the physical function scale with smaller differences across all subscales. For every 1 rise/s faster chair rise pace, we saw an estimated 16.0 (95% CI 9.1, 22.9) point increase in the physical function scale with smaller differences across all subscales. SF-36 scores were between 2.8 and 5.7 points higher among more physically active compared to less active patients. A 1 kg increase in grip strength was associated with a 0.2 (95% CI 0.01, 0.3) higher mental health score, but there were no differences in other subscales. VACS scores did not improve the model. Faster gait speed and chair rise time, and greater physical activity were associated with greater QoL, independent of HIV-related mortality risk. Targeted exercise programs to increase physical activity and improve speed and power should be evaluated as interventions to improve QoL during ART.

We identified correlates of perceived risk of HIV infection among persons who inject drugs (PWID) in Tijuana. 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. 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. 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.

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, psyphilis 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.
Full Text Available Abstract Background Even though it has been suggested that antiretroviral therapy has an impact on severe hypovitaminosis D (SHD in HIV infected patients, it could be speculated that the different levels of residual inflammation on HAART (Highly Active Anti Retroviral Therapy could contribute to SHD and aggravate bone catabolism in these patients. Methods A cross-sectional study was carried out in an unselected cohort of 263 HIV infected outpatients consulting during Spring 2010. Clinical examinations were performed and medical history, food habits, sun exposure and addictions were collected. Fasting blood samples were taken for immunological, virological, inflammation, endocrine and bone markers evaluations. Results Ninety-five (36% patients had SHD. In univariate analysis, a significant and positive association was found between SHD and IL6 (p = 0.001, hsCRP (p = 0.04, increased serum C-Telopeptides X (CTX (p = 0.005 and Parathyroid Hormon (PTH (p Conclusions SHD is frequent and correlates with inflammation in HIV infected patients. Since SHD is also associated with falls and increased bone catabolism, it may be of interest to take into account not only the type of antiretroviral therapy but also the residual inflammation on HAART in order to assess functional and bone risks. This finding also suggests that vitamin D supplementation may be beneficial in these HIV-infected patients.

HIV-infected individuals are 28 times more likely than the general population to be diagnosed with anal cancer. An integrative review of recommendations and guidelines for anal cancer screening was performed to provide a succinct guide to inform healthcare clinicians. The review excluded studies that were of non-HIV populations, redundant articles or publications, non-English manuscripts, or nonclinical trials. The review found no formal national or international guidelines exist for routine screening of anal cancer for HIV-infected individuals. To date, no randomized control trial provides strong evidence supporting efficaciousness and effectiveness of an anal cancer screening program. The screening recommendations from seven international-, national-, and state-based reports were reviewed and synthesized in this review. These guidelines suggest anal cancer screening, albeit unproven, may be beneficial at decreasing the incidence of anal cancer. This review highlights the paucity of screening-related research and is an area of need to provide clear direction and to define standard of care for anal cancer screening in HIV-infected persons.

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. PMID:20508736

Patients are increasingly using the Internet to obtain health-related information, communicate with providers and access research. Use of the Internet to obtain health-related information by low-income patients recently diagnosed with HIV infection has not been examined. In 2005, we surveyed 126 low-income patients diagnosed with HIV infection within the last three years. Eighty-five percent of the patients wereInternet to access information about HIV, 52% had never used the Internet, 28% had never used it to obtain health-related information and only 18% had done so at least monthly for the last six months. Two-thirds of the population studied would need instruction on how to use the Internet. In multivariable regression, 2004 income > or =$15,000 predicted monthly Internet use to obtain health-related information. Older age, heterosexual intercourse as HIV risk factor and inadequate health literacy were independent predictors of needing instruction. The low-income population with HIV infection lags behind the general population in Internet access and may not benefit from Internet-dependent advances in health communication, including HIV-related interventions.

Lung cancer is the most prevalent non-AIDS-defining malignancy in the highly active antiretroviral therapy era. Smoking plays a significant role in the development of HIV-associated lung cancer, but the cancer risk is two to four 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 most common histological subtype, and the majority of patients are diagnosed with locally advanced or metastatic carcinoma. Because 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 because this population is 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.

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.

Full Text Available Abstract Background The number of Koreans diagnosed with human immunodeficiency virus (HIV infections is increasing annually; however, CD4+ T-cell counts at diagnosis have decreased. The purpose of the present study was to identify clinical and epidemiologic associations with low CD4+ T-cell counts at the time of HIV diagnosis in a Korean population. Methods Data from 2,299 HIV-infected individuals with initial CD4+ T-cell counts measured within 6 months of HIV diagnosis and reason for HIV testing were recorded and measured from 2000 to 2007. Data were selected from the database of the Korea Centers for Disease Control and Prevention. Late diagnosis was defined by CD4+ T-cell counts 3. Reasons for HIV testing were analyzed using logistic regression including epidemiologic variables. Results A total of 858 individuals (37.3% were included in the late diagnosis group. Individuals with a late diagnosis were older, exposed through heterosexual contact, and demonstrated clinical manifestations of acquired immunodeficiency syndrome (AIDS. The primary reason for HIV testing was a routine health check-up (41% followed by clinical manifestations (31% of AIDS. The proportion of individuals with a late diagnosis was higher in individuals tested due to clinical symptoms in public health centers (adjusted odds ratio [AOR], 17.3; 95% CI, 1.7-175 and hospitals (AOR, 4.9; 95% CI, 3.4-7.2 compared to general health check-up. Late diagnosis annually increased in individuals diagnosed by voluntary testing both in public health centers (PHCs, P = 0.017 and in hospitals (P = 0.063. Routine testing due to risky behaviors resulted in earlier detection than testing secondary to health check-ups, although this difference was not statistically significant (AOR, 0.7; P = 0.187. Individuals identified as part of hospital health check-ups more frequently had a late diagnosis (P = 0.001 Conclusions HIV infection was primarily detected by voluntary testing with identification

Full Text Available Despite over two decades of extensive research showing that male circumcision protects against heterosexual acquisition of HIV in men, and that includes findings from large randomized controlled trials leading to acceptance by the WHO/UNAIDS and the Cochrane Committee, opponents of circumcision continue to generate specious arguments to the contrary. In a recent issue of the Journal of Public Health in Africa, Van Howe and Storms claim that male circumcision will increase HIV infections in Africa. Here we review the statements they use in support of their thesis and show that there is no scientific basis to such an assertion. We also evaluate the statistics used and show that when these data are properly analyzed the results lead to a contrary conclusion affirming the major role of male circumcision in protecting against HIV infection in Africa. Researchers, policy makers and the wider community should rely on balanced scholarship when assessing scientific evidence. We trust that our assessment may help refute the claims by Van Howe and Storms, and provide reassurance on the importance of circumcision for HIV prevention.

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 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.

Full Text Available Modern anti-retroviral therapy is highly effective at suppressing viral replication and restoring immune function in HIV-infected persons. However, such individuals show reduced physiological performance and increased frailty compared with age-matched uninfected persons. Contemporary anti-retroviral therapy is thought to be largely free from neuromuscular complications, whereas several anti-retroviral drugs previously in common usage have been associated with mitochondrial toxicity. It has recently been established that patients with prior exposure to such drugs exhibit irreversible cellular and molecular mitochondrial defects. However the functional significance of such damage remains unknown. Here we use phosphorus magnetic resonance spectroscopy ((31P-MRS to measure in vivo muscle mitochondrial oxidative function, in patients treated with contemporary anti-retroviral therapy, and compare with biopsy findings (cytochrome c oxidase (COX histochemistry. We show that dynamic oxidative function (post-exertional ATP (adenosine triphosphate resynthesis was largely maintained in the face of mild to moderate COX defects (affecting up to ∼10% of fibers: τ½ ADP (half-life of adenosine diphosphate clearance, HIV-infected 22.1±9.9 s, HIV-uninfected 18.8±4.4 s, p = 0.09. In contrast, HIV-infected patients had a significant derangement of resting state ATP metabolism compared with controls: ADP/ATP ratio, HIV-infected 1.24±0.08×10(-3, HIV-uninfected 1.16±0.05×10(-3, p = 0.001. These observations are broadly reassuring in that they suggest that in vivo mitochondrial function in patients on contemporary anti-retroviral therapy is largely maintained at the whole organ level, despite histochemical (COX defects within individual cells. Basal energy requirements may nevertheless be increased.

The use of single-tablet antiretroviral therapy (ART) regimens and its implications on adherence among HIV-infected women have not been well described. Participants were enrolled in the Women's Interagency HIV Study, a longitudinal study of HIV infection in US women. We examined semiannual trends in single-tablet regimen use and ART adherence, defined as self-reported 95% adherence in the past 6 months, during 2006-2013. In a nested cohort study, we assessed the comparative effectiveness of a single-tablet versus a multiple-tablet regimen with respect to adherence, virologic suppression, quality of life, and AIDS-defining events, using propensity score matching to account for demographic, behavioral, and clinical confounders. We also examined these outcomes in a subset of women switching from a multiple- to single-tablet regimen using a case-crossover design. We included 15,523 person-visits, representing 1727 women (53% black, 29% Hispanic, 25% IDU, median age 47). Use of single-tablet regimens among ART users increased from 7% in 2006% to 27% in 2013; adherence increased from 78% to 85% during the same period (both P Single-tablet regimen use was significantly associated with increased adherence (adjusted risk ratio: 1.05; 95% confidence interval: 1.03 to 1.08) and virologic suppression (risk ratio: 1.06; 95% confidence interval: 1.01 to 1.11), while associations with improved quality of life and fewer AIDS-defining events did not achieve statistical significance. Similar findings were observed among the subset of switchers. Single-tablet regimen use was associated with increased adherence and virologic suppression. Despite this, 15% of women prescribed ART were still not optimally adherent; additional interventions are needed to maximize therapeutic benefits.

Full Text Available It has not been determined whether implementation of combined prevention programming for persons who inject drugs reduce racial/ethnic disparities in HIV infection. We examine racial/ethnic disparities in New York City among persons who inject drugs after implementation of the New York City Condom Social Marketing Program in 2007. Quantitative interviews and HIV testing were conducted among persons who inject drugs entering Mount Sinai Beth Israel drug treatment (2007-2014. 703 persons who inject drugs who began injecting after implementation of large-scale syringe exchange were included in the analyses. Factors independently associated with being HIV seropositive were identified and a published model was used to estimate HIV infections due to sexual transmission. Overall HIV prevalence was 4%; Whites 1%, African-Americans 17%, and Hispanics 4%. Adjusted odds ratios were 21.0 (95% CI 5.7, 77.5 for African-Americans to Whites and 4.5 (95% CI 1.3, 16.3 for Hispanics to Whites. There was an overall significant trend towards reduced HIV prevalence over time (adjusted odd ratio = 0.7 per year, 95% confidence interval (0.6-0.8. An estimated 75% or more of the HIV infections were due to sexual transmission. Racial/ethnic disparities among persons who inject drugs were not significantly different from previous disparities. Reducing these persistent disparities may require new interventions (treatment as prevention, pre-exposure prophylaxis for all racial/ethnic groups.
Full Text Available This study estimated the proportions and numbers of heterosexuals in the United States (U.S. to calculate rates of heterosexually acquired human immunodeficiency virus (HIV infection. Quantifying the burden of disease can inform effective prevention planning and resource allocation.Heterosexuals were defined as males and females who ever had sex with an opposite-sex partner and excluded those with other HIV risks: persons who ever injected drugs and males who ever had sex with another man. We conducted meta-analysis using data from 3 national probability surveys that measured lifetime (ever sexual activity and injection drug use among persons aged 15 years and older to estimate the proportion of heterosexuals in the United States population. We then applied the proportion of heterosexual persons to census data to produce population size estimates. National HIV infection rates among heterosexuals were calculated using surveillance data (cases attributable to heterosexual contact in the numerators and the heterosexual population size estimates in the denominators.Adult and adolescent heterosexuals comprised an estimated 86.7% (95% confidence interval: 84.1%-89.3% of the U.S. population. The estimate for males was 84.1% (CI: 81.2%-86.9% and for females was 89.4% (95% CI: 86.9%-91.8%. The HIV diagnosis rate for 2013 was 5.2 per 100,000 heterosexuals and the rate of persons living with diagnosed HIV infection in 2012 was 104 per 100,000 heterosexuals aged 13 years or older. Rates of HIV infection were >20 times as high among black heterosexuals compared to white heterosexuals, indicating considerable disparity. Rates among heterosexual men demonstrated higher disparities than overall population rates for men.The best available data must be used to guide decision-making for HIV prevention. HIV rates among heterosexuals in the U.S. are important additions to cost effectiveness and other data used to make critical decisions about resources for

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 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 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.

Initiating antiretroviral therapy (ART) early improves clinical outcomes and prevents transmission. Guidelines for first-line therapy have changed with the availability of newer ART agents. In this study, we compared persistence and virologic responses with initial ART according to the class of anchor agent used. An observational clinical cohort study in the Southeastern United States. All HIV-infected patients participating in the UNC Center for AIDS Research Clinical Cohort (UCHCC) and initiating ART between 1996 and 2014 were included. Separate time-to-event analyses with regimen discontinuation and virologic failure as outcomes were used, including Kaplan-Meier survival curves and adjusted Cox proportional hazards models. One thousand six hundred twenty-four patients were included (median age of 37 years at baseline, 28% women, 60% African American, and 28% white). Eleven percent initiated integrase strand transfer inhibitor (INSTI), 33% non-nucleoside reverse transcriptase inhibitor (NNRTI), 20% boosted protease inhibitor, 27% other, and 9% NRTI only regimens. Compared with NNRTI-containing regimens, INSTI-containing regimens had an adjusted hazard ratio of 0.49 (95% confidence interval, 0.35 to 0.69) for discontinuation and 0.70 (95% confidence interval, 0.46 to 1.06) for virologic failure. All other regimen types were associated with increased rates of discontinuation and failure compared with NNRTI. Initiating ART with an INSTI-containing regimen was associated with lower rates of regimen discontinuation and virologic failure.
Full Text Available PURPOSE: Noninfectious comorbidities such as cardiovascular diseases have become increasingly prevalent and occur earlier in life in persons with HIV infection. Despite the emerging body of literature linking environmental exposures to chronic disease outcomes in the general population, the impacts of environmental exposures have received little attention in HIV-infected population. The aim of this study is to investigate whether individuals living with HIV have elevated prevalence of heavy metals compared to non-HIV infected individuals in United States. METHODS: We used the National Health and Nutrition Examination Survey (NHANES 2003-2010 to compare exposures to heavy metals including cadmium, lead, and total mercury in HIV infected and non-HIV infected subjects. RESULTS: In this cross-sectional study, we found that HIV-infected individuals had higher concentrations of all heavy metals than the non-HIV infected group. In a multivariate linear regression model, HIV status was significantly associated with increased blood cadmium (p=0.03 after adjusting for age, sex, race, education, poverty income ratio, and smoking. However, HIV status was not statistically associated with lead or mercury levels after adjusting for the same covariates. CONCLUSIONS: Our findings suggest that HIV-infected patients might be significantly more exposed to cadmium compared to non-HIV infected individuals which could contribute to higher prevalence of chronic diseases among HIV-infected subjects. Further research is warranted to identify sources of exposure and to understand more about specific health outcomes.

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.

Studies have documented the substantial risk of human immunodeficiency virus (HIV) infection endured by sex-trafficked women, but it remains unclear how exposure to trafficking puts its victims at risk. We assessed whether the association between sex trafficking and HIV could be explained by self-reported forced prostitution or young age at entry into prostitution using cross-sectional data collected from 1,814 adult female sex workers in Karnataka, India, between August 2005 and August 2006. Marginal structural logistic regression was used to estimate adjusted odds ratios for HIV infection. Overall, 372 (21%) women met 1 or both criteria used to define sex trafficking: 278 (16%) began sex work before age 18 years, and 107 (5%) reported being forcibly prostituted. Thirteen (0.7%) met both criteria. Forcibly prostituted women were more likely to be HIV-infected than were women who joined the industry voluntarily, independent of age at entering prostitution (odds ratio = 2.30, 95% confidence interval: 1.08, 4.90). Conversely, after adjustment for forced prostitution and other confounders, no association between age at entry into prostitution and HIV was observed. The association between forced prostitution and HIV infection became stronger in the presence of sexual violence (odds ratio = 11.13, 95% confidence interval: 2.41, 51.40). These findings indicate that forced prostitution coupled with sexual violence probably explains the association between sex trafficking and HIV. PMID:23324332

The aims of the study were to describe the prevalence and associations of mental health disorder (MHD) among a cohort of HIV-infected patients attending the Victorian HIV/AIDS Service between 1984 and 2000, and to examine whether antiretroviral therapy use or mortality was influenced by MHD (defined as a record of service provision by psychiatric services on the Victorian Psychiatric Case Register). It was hypothesized that HIV-positive individuals with MHD would have poorer treatment outcomes, reduced responses to highly active antiretroviral therapy (HAART) and increased mortality compared with those without MHD. This is a retrospective cohort of 2981 individuals (73% of the Victorian population diagnosed with HIV infection) captured on an HIV database which was electronically matched with the public Victorian Psychiatric Case Register (VPCR) (accounting for 95% of public system psychiatry service provision). The prevalence, dates and recorded specifics of mental health disorders at the time of the electronic match on 1 June 2000 are described. The association with recorded MHD, gender, age, AIDS illness, HIV exposure category, duration and type of antiviral therapy, treatment era (prior to 1986, post-1987 and pre-HAART, and post-HAART) on hospitalization and mortality at 1 September 2001 was assessed. Five hundred and twenty-five individuals (17.6% of the Victorian HIV-positive population) were recorded with MHD, most frequently coded as attributable to substance dependence/abuse or affective disorder. MHD was diagnosed prior to HIV in 33% and, of those diagnosed after HIV, 93.8% were recorded more than 1 year after the HIV diagnosis. Schizophrenia was recorded in 6% of the population with MHD. Hospitalizations for both psychiatric and nonpsychiatric illness were more frequent in those with MHD (relative risk 5.4; 95% confidence interval 3.7, 8.2). The total number of antiretrovirals used (median 6.4 agents vs 5.5 agents) was greater in those with MHD. When

We examined whether sex disparities (heterosexual male:female) in HIV infection continue to persist at the "end of the HIV epidemic" among persons who inject drugs (PWID) in New York City (NYC). An "end of the epidemic" was operationally defined as 1) prevalence of untreated HIV infection <5%, and 2) estimated HIV incidence <0.5/100 person-years. PWID were recruited from persons entering substance use treatment programs at Mount Sinai Beth Israel in 2001-2005 and 2011-2015. A structured interview was administered, and HIV and HSV-2 testing was conducted. Incidence was estimated using newly diagnosed cases of HIV. Disparity analyses compared prevalence of HIV, of untreated HIV, HIV risk behaviors, and estimated HIV incidence. By 2011-2015, both heterosexual male and female PWID met the two criteria for an "end of the epidemic," and there were no significant differences in the prevalence of untreated HIV infection. A large sex difference remained in estimated HIV incidence. In 2013-2015, estimated HIV incidence was 2.8/10,000 PY for males and 7.1/10,000 PY for females. Females had greater risk for HIV on several factors. While NYC has reached an "end of the epidemic" for both heterosexual male and female PWID, sex disparities persist, particularly differences in HIV incidence. Eliminating the sex disparities may require a greater focus on factors associated with sexual transmission. Copyright © 2018 Elsevier B.V. All rights reserved.
Full Text Available Introduction: People with AIDS can have a dysfunction of the hypothalamic - pituitary-adrenal axis. With regard to HIV infection, most often mentioned is iatrogenic Cushing's syndrome or Pseudo-Cushing's Syndrome. So far there are described only two cases of Cushing disease in HIV -infected persons. Case report: A 48-year-old patient, after eleven years of HIV infection and a year since the introduction of HAART, was diagnosed with Cushing's disease based on cushingoid habitus, lack of suppression of cortisol in screening, elevated ACTH and pituitary tumor. She had transfenoidal surgery and histopathologic findings corresponded to basophilic adenoma. After the operation, short time on hydrocortisone substitution, she generally felt well with regular ART. Four years later, again easily bruising, facial redness, oily skin with acne, weight gain, uneven distribution of stomach adipose tissue, sweating, oligomenorrhea and high blood pressure. There was no rest/relapse of tumor on control pituitary MRI. Initially, elevated ACTH, valid cortisol in daily profiles, later the absence of the suppression of cortisol after 4 mg (LDST and 8 mg (HDST of dexamethasone along with maintenance of higher ACTH, indicate recurrence of clinical and laboratory relapse wherefore ketoconazole was introduced. Despite increasing doses of ketoconazole, she held slightly higher morning cortisol, ACTH and with persisting Cushing's syndrome. Conclusion: The coexistence of the two entities could lead to overlapping metabolic and phenotypic characteristics and the interaction between and/or synergism.
Full Text Available The management of Human Immunodeficiency Virus (HIV infection is progressing rapidly. In developed countries, the perinatal transmission rates have decreased from 20-30% to 1-2% with the use of antiretroviral therapy and cesarean section. Interventions for the prevention of prenatal transmission has made the prenatal care of pregnant patients with HIV infection more complex. Rapid development of standard care and continuing increase in the distribution of HIV infection has required clinicians taking care of pregnants to have current information. Therefore, in our review we aimed to summarize the prenatal course, treatment and preventive methods for perinatal transmission of HIV. [Archives Medical Review Journal 2016; 25(4.000: 522-535

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

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.

Full Text Available OBJECTIVES: To determine whether for a given waist circumference (WC, a larger hip circumference (HC was associated with a reduced risk of insulin resistance, type 2 diabetes (T2D, hypertension and cardiovascular disease (CVD in HIV-infected patients. A second objective was to determine whether, for a given WC, the addition of HC improved upon estimates of abdominal adiposity, in particular visceral adipose tissue (VAT, compared to those obtained by WC alone. METHODS: HIV-infected men (N = 1481 and women (N = 841 were recruited between 2005 and 2009. WC and HC were obtained using standard techniques and abdominal adiposity was measured using computed tomography. RESULTS: After control for WC and covariates, HC was negatively associated with risk of insulin resistance (p<0.05 and T2D [Men: OR = 0.91 (95% CI: 0.86-0.96; Women: OR = 0.91 (95% CI: 0.84-0.98]. For a given WC, HC was also negatively associated with a lower risk of hypertension (p<0.05 and CVD [OR = 0.94 (95% CI: 0.88-0.99] in men, but not women. Although HC was negatively associated with VAT in men and women after control for WC (p<0.05, the addition of HC did not substantially improve upon the prediction of VAT compared to WC alone. CONCLUSIONS: The identification of HIV-infected individuals at increased health risk by WC alone is substantially improved by the addition of HC. Estimates of visceral adipose tissue by WC are not substantially improved by the addition of HC and thus variation in visceral adiposity may not be the conduit by which HC identifies increased health risk.

Most clinical guidelines recommend that AIDS-free, HIV-infected persons with CD4 cell counts below 0.350 × 10(9) cells/L initiate combined antiretroviral therapy (cART), but the optimal CD4 cell count at which cART should be initiated remains a matter of debate. To identify the optimal CD4 cell

Metabolic and morphologic abnormalities in persons with HIV remain common contributors to stigma and morbidity. Increased abdominal circumference and visceral adiposity were first recognized in the late 1990s, soon after the advent of effective combination antiretroviral therapy. Visceral adiposity
Lake, Jordan E
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.
Full Text Available The optimal duration of preventive therapy for tuberculosis (TB among HIV-infected persons in TB-endemic countries is unknown.An open-label randomized clinical trial was performed and analyzed for equivalence. Seven hundred and twelve HIV-infected, ART-naïve patients without active TB were randomized to receive either ethambutol 800 mg and isoniazid 300 mg daily for six-months (6EH or isoniazid 300 mg daily for 36-months (36H. Drugs were dispensed fortnightly and adherence checked by home visits. Patients had chest radiograph, sputum smear and culture performed every six months, in addition to investigations if they developed symptoms. The primary endpoint was incident TB while secondary endpoints were all-cause mortality and adverse events. Survival analysis was performed on the modified intent to treat population (m-ITT and rates compared.Tuberculosis developed in 22 (6.4% of 344 subjects in the 6EH arm and 13 (3.8% of 339 subjects in the 36H arm with incidence rates of 2.4/100 py (95%CI- 1.4-3.5 and 1.6/100 py (95% CI-0.8-3.0 with an adjusted rate ratio (aIRR of 1.6 (0.8-3.2. Among TST-positive subjects, the aIRR of 6EH was 1.7 (0.6-4.3 compared to 36H, p = 0.8. All-cause mortality and toxicity were similar in the two arms. Among 15 patients with confirmed TB, 4 isolates were resistant to isoniazid and 2 were multidrug-resistant.Both regimens were similarly effective in preventing TB, when compared to historical incidence rates. However, there was a trend to lower TB incidence with 36H. There was no increase in isoniazid resistance compared to the expected rate in HIV-infected patients. The trial is registered at ClinicalTrials.gov, NCT00351702.

Current guidelines recommend that women with HIV infection receive annual cervical smears. We evaluated the uptake of annual cervical smears by women with HIV infection under the care of the Infectious Disease Service at Auckland City Hospital. In an attempt to identify potential barriers to regularly receiving an annual cervical smear, we invited the women to complete a questionnaire. The responses from women who had regularly received an annual cervical smear were compared with those who had not. The proportion of women who had received a cervical smear increased from 44% in 2001, to 73% in 2010 (p=0.001). Ninety-three women (76%) completed the study questionnaire. No statistically significant differences were found in the questionnaire responses between the women who had regularly received an annual cervical smear and those who had not. The proportion of women in this cohort who received a cervical smear in 2010 is comparable with other studies of women with HIV infection in New Zealand and overseas. We have not been able to identify barriers that prevent women with HIV infection in Auckland regularly receiving an annual cervical smear. We plan to encourage women who have not received a cervical smear in the previous 2-year period to have a cervical smear performed when they attend the Infectious Disease Clinic, and will continue to notify the National Cervical Screening Programme that all women who are newly diagnosed with HIV infection should have an annual recall code attached to future cervical smear reports. We expect that these interventions will further increase the proportion of women with HIV infection in Auckland who receive an annual cervical smear.
Full Text Available Abstract Background The devastating impact of AIDS in the world especially in sub-Saharan Africa has led to an unprecedented global effort to ensure access to antiretroviral (ARV drugs. Given that medication-taking behavior can immensely affect an individual's response; ART adherence is now widely recognized as an 'Achilles heel' for the successful outcome. The present study was undertaken to investigate the rate and predictors of adherence to antiretroviral therapy among HIV-infected persons in southwest Ethiopia. Methods The study was conducted in the antiretroviral therapy unit of Jimma University Specialized Hospital. A prospective study was undertaken on a total of 400 HIV infected person. Data were collected using a pre-tested interviewer-administered structured questionnaire at first month (M0 and third month (M3 follow up visits. Results A total of 400 and 383 patients at baseline (M0 and at follow up visit (M3 respectively were interviewed. Self-reported dose adherence in the study area was 94.3%. The rate considering the combined indicator (dose, time and food was 75.7%. Within a three month follow up period, dose adherence decreased by 2% and overall adherence rate decreased by more than 3%. Adherence was common in those patients who have a social support (OR, 1.82, 95%CI, 1.04, 3.21. Patients who were not depressed were two times more likely to be adherent than those who were depressed (OR, 2.13, 95%CI, 1.18, 3.81. However, at the follow up visit, social support (OR, 2.42, 95%CI, 1.29, 4.55 and the use of memory aids (OR, 3.29, 95%CI, 1.44, 7.51 were found to be independent predictors of adherence. The principal reasons reported for skipping doses in this study were simply forgetting, feeling sick or ill, being busy and running out of medication in more than 75% of the cases. Conclusion The self reported adherence rate was high in the study area. The study showed that adherence is a dynamic process which changes overtime and cannot

Repeated exposure to childhood adversity (abuse, neglect and other traumas experienced before age 18) can have lifelong impacts on health. For HIV-infected adolescents and youth, such impacts may include onward transmission of HIV. To evaluate this possibility, the current study measured the burden of childhood adversity and its influence on risky health behaviors among perinatally-infected adolescents and youth. We surveyed 250 perinatally-infected adolescents and youth (13-24 years) receiving care in Soweto, South Africa. Both male and female participants reported on childhood adversity (using the ACE-IQ), sexual behavior, and psychosocial state. Viral load was also abstracted from their charts. We used logistic regressions to test the association between cumulative adversity and behavioral outcomes. Half the sample reported eight or more adversities. Overall, 72% experienced emotional abuse, 59% experienced physical abuse, 34% experienced sexual abuse, 82% witnessed domestic violence, and 91% saw someone being attacked in their community. A clear gradient emerged between cumulative adversities and behavioral risk. Having experienced one additional childhood adversity raised the odds of risky sexual behavior by almost 30% (OR 1.27, 95% CI 1.09-1.48). Viral suppression was poor overall (31% had viral loads >400 copies/ml), but was not related to adversity. Adversity showed a robust relationship to depression and substance abuse. Childhood adversity is common, influences the current health of HIV-positive adolescents and youth, and puts their sexual partners at risk for HIV infection. Greater primary prevention of childhood adversity and increased access to support services (e.g., mental health) could reduce risk taking among HIV-positive adolescents and youth.

Full Text Available A clinical and epidemiological study for 14 years was conducted. Among TB patients, the percentage of persons with mixed infection (TB+HIV infection increased during the observation period from 10 up to 64%. About one third of them had a pleura reaction with an accumulation of fluid between pleura’s petals. Pleuritis in patients with mixed infection were characterized by special features: pleurisy complicated another form of tuberculosis more often, in one-third of patients (29,8% pleural liquid had hemorrhagic type, Mycobacterium tuberculosis in the pleural fluid was detected six times more often. The level of activity of adenosine deaminase and neopterin in the exudate of patients with tuberculosis and HIV infection remained significantly higher than in the control group of persons. These data can be useful in the diagnostics of specific diseases in HIV-infected patients.

Full Text Available Abstract Background To examine demographic and behavioral associations with self-reported health-related quality of life (HRQOL among persons with HIV infection or AIDS. Methods Analysis of interviews with persons ≥ 18 years of age reported through routine disease surveillance with HIV infection or AIDS to nine state and local health departments from January 1995 through December 1996. Scales were constructed from validated measures of HRQOL, and mean scores were calculated (lower scores signified poorer HRQOL. Measures of HRQOL included Overall Health, Pain, Physical Functioning, Role Functioning, Social Functioning, Mental Health, Energy/Fatigue, and Cognitive Functioning. Differences in HRQOL were examined by various demographic and behavioral factors, including taking antiretroviral medication. Results HRQOL data were available for 3778 persons. Factors associated with lower HRQOL scores included older age, female sex, black or Hispanic race/ethnicity, injection drug use, lower education and income, no private health insurance, and lower CD4 count. In multivariate analysis, lower CD4 count was the factor most consistently associated with lower HRQOL. Taking antiretroviral medication was not associated with differences in HRQOL regardless of CD4 count. Conclusions Perception of HRQOL varied in a population with HIV infection or AIDS. On most HRQOL measures, lower CD4 count was associated with lower HRQOL. Measurement of HRQOL can assist in understanding the long-term effects of disease and treatment on persons with HIV.

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.

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.

With increasing success in treating HIV, infected persons are living longer, and a new challenge has emerged - the need to understand how HIV-infected adults are aging. What are the similarities with typical aging and what are the unique aspects that may have resulted from HIV infection, interacting with characteristic life style factors and other comorbid conditions? Are specific diseases and conditions (comorbidities), typically seen as part of the aging process, occurring at accelerated rates or with higher frequency (accentuated) in HIV-infected adults? At this juncture, conclusions should be tentative. Certainly, biological processes that correlate with aging occur earlier in the older adult HIV population. Clinical manifestations of these biological processes are age-associated illnesses occurring in greater numbers (multimorbidity), but they are not accelerated. Specifically cardiovascular disease, certain cancers, and renal disease are more common with other comorbidities less certain. Management of this elevated risk for developing multimorbidity is a major concern for patients and their health care teams. The medical system must respond to the evolving needs of this aging and growing older adult population who will dominate the epidemic. Adopting a more holistic approach to their health care management is needed to achieve optimal health and well-being in the HIV-infected older adult. Geriatric care principles best embody this approach. © 2017 S. Karger AG, Basel.
Full Text Available Nancy Nguyen1, Mark Holodniy21University of the Pacific School of Pharmacy and Health Sciences, Stockton, CA, USA; 2VA Palo Alto Health Care System, Palo Alto, CA, USAAbstract: In the US, an estimated 1 million people are infected with HIV, although one-third of this population are unaware of their diagnosis. While HIV infection is commonly thought to affect younger adults, there are an increasing number of patients over 50 years of age living with the condition. UNAIDS and WHO estimate that of the 40 million people living with HIV/AIDS in the world, approximately 2.8 million are 50 years and older. With the introduction of highly active antiretroviral therapy (HAART in the mid-1990s, survival following HIV diagnosis has risen dramatically and HIV infection has evolved from an acute disease process to being managed as a chronic medical condition. As treated HIV-infected patients live longer and the number of new HIV diagnoses in older patients rise, clinicians need to be aware of these trends and become familiar with the management of HIV infection in the older patient. This article is intended for the general clinician, including geriatricians, and will review epidemiologic data and HIV treatment as well as provide a discussion on medical management issues affecting the older HIV-infected patient.Keywords: HIV, epidemiology, treatment, aging, review

Currently, there are around 150,000 HIV-infected patients in Spain. This number, together with the fact that this disease is now a chronic condition since the introduction of antiretroviral therapy, has generated an increasing demand on the clinical microbiology laboratories in our hospitals. This increase has occurred not only in the diagnosis and treatment of opportunistic diseases, but also in tests related to the diagnosis and therapeutic management of HIV infection. To meet this demand, the Sociedad de Enfermedades Infecciosas y Microbiología Clinica (Spanish Society of Infectious Diseases and Clinical Microbiology) has updated its standard Procedure for the microbiological diagnosis of HIV infection. The main advances related to serological diagnosis, plasma viral load, and detection of resistance to antiretroviral drugs are reviewed in this version of the Procedure.
In the era of modern combination antiretroviral therapy (cART) the HIV-infected population is ageing. Studies have suggested that HIV-infected individuals, even if appropriately treated with cART, may be at increased risk for several age-related conditions. In this thesis a variety of age-related

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.
Full Text Available HIV persists because a reservoir of latently infected CD4 T cells do not express viral proteins and are indistinguishable from uninfected cells. One approach to HIV cure suggests that reactivating HIV will activate cytotoxic pathways; yet when tested in vivo, reactivating cells do not die sufficiently to reduce cell-associated HIV DNA levels. We recently showed that following reactivation from latency, HIV infected cells generate the HIV specific cytotoxic protein Casp8p41 which is produced by HIV protease cleaving procaspase 8. However, cell death is prevented, possibly due to low procaspase 8 expression. Here, we tested whether increasing procaspase 8 levels in CD4 T cells will produce more Casp8p41 following HIV reactivation, causing more reactivated cells to die. Screening 1277 FDA approved drugs identified 168 that increased procaspase 8 expression by at least 1.7-fold. Of these 30 were tested for anti-HIV effects in an acute HIVIIIb infection model, and 9 drugs at physiologic relevant levels significantly reduced cell-associated HIV DNA. Primary CD4 T cells from ART suppressed HIV patients were treated with one of these 9 drugs and reactivated with αCD3/αCD28. Four drugs significantly increased Casp8p41 levels following HIV reactivation, and decreased total cell associated HIV DNA levels (flurbiprofen: p = 0.014; doxycycline: p = 0.044; indomethacin: p = 0.025; bezafibrate: P = 0.018 without effecting the viability of uninfected cells. Thus procaspase 8 levels can be increased pharmacologically and, in the context of HIV reactivation, increase Casp8p41 causing death of reactivating cells and decreased HIV DNA levels. Future studies will be required to define the clinical utility of this or similar approaches.

We investigated whether the experience of homophobic events increases the odds of engaging in unprotected anal intercourse (UAI) among black men who have sex with men (MSM) and whether social integration level buffered the association. Participants (N = 1,154) reported homophobic events experienced in the past 12 months. Social integration measures included social support, closeness with family members and friends, attachment to the black gay community, openness about sexuality within religious communities, and MSM social network size. Logistic regression analyses indicated that experiencing homophobia was associated with (1) UAI among men not previously diagnosed with HIV and (2) sexual HIV transmission risk behavior among men who knew they were HIV-infected. None of the social integration measures buffered these associations. Homophobia may promote acquisition and transmission of HIV infection among black MSM. Interventions are needed to reduce homophobia experienced by black MSM.

Little is known about how HIV affects undocumented immigrants despite social and structural factors that may place them at risk of poor HIV outcomes. Our understanding of the clinical epidemiology of HIV-infected undocumented immigrants is limited by the challenges of determining undocumented immigration status in large data sets. We developed an algorithm to predict undocumented status using social security number (SSN) and insurance data. We retrospectively applied this algorithm to a cohort of HIV-infected adults receiving care at a large urban healthcare system who attended at least one HIV-related outpatient visit from 1997 to 2013, classifying patients as "screened undocumented" or "documented". We then reviewed the medical records of screened undocumented patients, classifying those whose records contained evidence of undocumented status as "undocumented per medical chart" (charted undocumented). Bivariate measures of association were used to identify demographic and clinical characteristics associated with undocumented immigrant status. Of 7593 patients, 205 (2.7%) were classified as undocumented by the algorithm. Compared to documented patients, undocumented patients were younger at entry to care (mean 38.5 years vs. 40.6 years, p immigrants within an HIV-infected population, though it overestimated the prevalence of patients who were undocumented.

). 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.
Full Text Available HIV infection is associated with an increased risk of age-related morbidity mediated by immune dysfunction, atherosclerosis and inflammation. Changes in retinal vessel calibre may reflect cumulative structural damage arising from these mechanisms. The relationship of retinal vessel calibre with clinical and demographic characteristics was investigated in a population of HIV-infected individuals in South Africa.Case-control study of 491 adults ≥30 years, composed of 242 HIV-infected adults and 249 age- and gender-matched HIV-negative controls. Retinal vessel calibre was measured using computer-assisted techniques to determine mean arteriolar and venular diameters of each eye.The median age was 40 years (IQR: 35-48 years. Among HIV-infected adults, 87.1% were receiving highly active antiretroviral therapy (HAART (median duration, 58 months, their median CD4 count was 468 cells/µL, and 84.3% had undetectable plasma viral load. Unadjusted mean retinal arteriolar diameters were 163.67±17.69 µm in cases and 161.34±17.38 µm in controls (p = 0.15. Unadjusted mean venular diameters were 267.77±18.21 µm in cases and 270.81±18.98 µm in controls (p = 0.07. Age modified the effect of retinal arteriolar and venular diameters in relation to HIV status, with a tendency towards narrower retinal diameters in HIV cases but not in controls. Among cases, retinal arteriolar diameters narrowed with increasing duration of HAART, independently of age (167.83 µm 6 years, p-trend = 0.02, and with a HIV viral load >10,000 copies/mL while on HAART (p = 0.05. HIV-related venular changes were not detected.Narrowing of retinal arteriolar diameters is associated with HAART duration and viral load, and may reflect heightened inflammatory and pro-atherogenic states of the systemic vasculature. Measurement of retinal vascular calibre could be an innovative non-invasive method of estimating vascular risk in HIV-infected individuals.

Médecins Sans Frontières is supporting comprehensive HIV care and treatment for Kaposi Sarcoma (KS) in Guinea, where antiretroviral coverage is low and access to KS treatment is very limited. We aimed to evaluate treatment response and survival outcomes of epidemic KS in this setting. Retrospective survival analysis of routinely collected clinical data of HIV-infected patients with clinically diagnosed KS, receiving ART and chemotherapy consisting of a combination of bleomycin and vincristine at the Donka National Hospital in Conakry between 2012 and 2015. A total of 225 patients were enrolled for KS treatment within the three-year period. Late presentation with stage T1 disease was common (82.7%). At the end of a median of 8 cycles of chemotherapy (IQR: 2-12), complete remission was observed in 65 (28.9%), partial remission in 53 (23.6%), stable disease in 15 (6.7%) and unknown response for all 92 (40.9%) patients who dropped out of care. The chances of achieving complete remission doubled after each additional cycle of chemotherapy (aOR = 2.09 95% CI: 1.44-3.01) but were reduced by about two-thirds for each additional month delay between treatment and onset of KS (aOR = 0.31, 95% CI: 0.11-0.86). Treatment response was seriously compromised in patients with woody skin oedema (aOR = 0.05, 95% CI: 0.01-0.38) and those with prior chemotherapy (aOR = 0.21, 95% CI: 0.05-0.80). The median survival time was 7.6 months (95% CI: 5.9-9.8). Attrition from care was reduced by 22% for every additional cycle of chemotherapy administered (aH0R = 0.78, 95% CI: 0.71-0.84) and was lower in those with complete remission compared with those with partial or no response (aHR = 0.05, 95% CI: 0.007-0.43). There has been an increased access to KS treatment. The overall response rate is 52.4%, which is considered a satisfactory result. Poor outcomes were common and were largely due to late presentation and defaulting on treatment. Efforts towards early HIV

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.

Full Text Available By 2020 the prevalence of HIV in the Russian Federation may increase by 250%, unless we provide appropriate treatment to as many HIV-infected people as possible (V.I. Skvortsova, 2015. Previous research in this field shows that the psychotraumatic character of the disease lowers the psychological resource of HIV-infected individuals. In most cases, they are not psychologically prepared for the negative life events, unable to find an optimal behavioral pattern when their life stereotypes are being destroyed. In fact, being HIV-infected is an example of an acute event (V.V. Pokrovsky, 1993. The ability to overcome the life crisis and effectiveness of using adaptation and compensatory mechanisms to fight the disease depend on the level of adaptation to the fact of being infected and resistance to stress. The aim of the current study was to determine social and psychological features of HIV-infected individuals and assess their influence on the stress resistance and adaptation abilities of HIV+ patients. We observed men and women aged 21-30 who had been HIV+ for 1-5 years. Investigation methods included the following diagnostic tools: The Cattel Sixteen Personality Factor Questionnaire (Form C, The State-Trait Anxiety Inventory (conducted by Spielberger, adapted for use in Russia by Hanin, The Social Readjustment Rating Scale (The Holmes-Rahe Stress Inventory, The Social and Psychological Adaptation Questionnaire (by C. Rogers and R. Diamond, methods of mathematical statistics. As a result of the study, we have developed comparative factor profiles of individual psychological features of HIV-infected individuals that show their dependence on the social environment and form certain behavioral patterns. We have revealed significant difference in state and trait anxiety between HIV-infected and non-HIV-infected individuals. Self-blame, inadequate self-esteem and level of aspiration indicate low cognitive assessment of the condition by the patients
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.

Hepatitis B virus (HBV) infection is common in HIV-infected persons and is associated with increased risk of liver-related morbidity and mortality. Agents available to treat HBV infection in coinfected patients include lamivudine, entecavir, emtricitabine, adefovir, peginterferon alfa, and the recently approved telbivudine. Treatment decisions should take into account a number of factors, including antiretroviral therapy status, HBV genotype, prior experience of lamivudine, and the need to avoid drug resistance in both HIV- and HBV-infected persons. This article summarizes a presentation on treatment and management of HBV infection in HIV-infected patients made by Chloe L. Thio, MD, at the 9th Annual Ryan White CARE Act Update in Washington, DC. The original presentation is available as a Webcast at www.iasusa.org.

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.

Full Text Available This study aims to estimate the risk of cardiovascular disease (CVD and to assess the agreement between the Framingham, Framingham with aggravating factors, PROCAM, and DAD equations in HIV-infected patients. A cross-sectional study was conducted in an outpatient centre in Brazil. 294 patients older than 19 years were enrolled. Estimates of 10-year cardiovascular risk were calculated. The agreement between the CVD risk equations was assessed using Cohen's kappa coefficient. The participants' mean age was 36.8 years (SD = 10.3, 76.9% were men, and 66.3% were on antiretroviral therapy. 47.8% of the participants had abdominal obesity, 23.1% were current smokers, 20.0% had hypertension, and 2.0% had diabetes. At least one lipid abnormality was detected in 72.8%, and a low HDL-C level was the most common. The majority were classified as having low risk for CV events. The percentage of patients at high risk ranged from 0.4 to 5.7. The PROCAM score placed the lowest proportion of the patients into a high-risk group, and the Framingham equation with aggravating factors placed the highest proportion of patients into the high-risk group. Data concerning the comparability of different tools are informative for estimating the risk of CVD, but accuracy of the outcome predictions should also be considered.

Full Text Available In the last 15 years, highly active antiretroviral therapy (HAART has determined a dramatic reduction of both morbidity and mortality in human immunodeficiency virus (HIV-infected subjects, transforming this infection in a chronic and manageable disease. Patients surviving with HIV in the developed world, in larger number men, are becoming aged. As it would be expected for a population of comparable age, many HIV-infected individuals report a family history of cardiovascular disease, a small proportion have already experienced a cardiovascular event and an increasing proportion has diabetes mellitus. Smoking rate is very high while an increasing proportion of HIV-infected individuals have dyslipidaemia. Studies suggest that these traditional risk factors could play an important role in the development of cardiovascular disease in these patients as they do in the general population. Thus, whilst the predicted 10-year cardiovascular disease risk remains relatively low at present, it will likely increase in relation to the progressive aging of this patient population. Thus, the long-term follow-up of HIV infected patients has to include co-morbidity management such as cardiovascular disease prevention and treatment. Two intriguing aspects related to the cardiovascular risk in patients with HIV infection are the matter of current investigation: 1 while these subjects share many cardiovascular risk factors with the general population, HIV infection itself increases cardiovascular risk; 2 some HAART regimens too influence atherosclerotic profile, partly due to lipid changes. Although the mechanisms involved in the development of cardiovascular complications in HIV-infected patients remain to be fully elucidated, treatment guidelines recommending interventions to prevent cardiovascular disease in these individuals are already available; however, their application is still limited.

Full Text Available The induction of a broadly neutralizing antibody (BNAb response against HIV-1 would be a desirable feature of a protective vaccine. Vaccine strategies thus far have failed to elicit broadly neutralizing antibody responses; however a minority of HIV-infected patients do develop circulating BNAbs, from which several potent broadly neutralizing monoclonal antibodies (mAbs have been isolated. The findings that several BNmAbs exhibit autoreactivity and that autoreactive serum antibodies are observed in some HIV patients have advanced the possibility that enforcement of self-tolerance may contribute to the rarity of BNAbs. To examine the possible breakdown of tolerance in HIV patients, we utilized the 9G4 anti-idiotype antibody system, enabling resolution of both autoreactive VH4-34 gene-expressing B cells and serum antibodies. Compared with healthy controls, HIV patients had significantly elevated 9G4+ serum IgG antibody concentrations and frequencies of 9G4+ B cells, a finding characteristic of systemic lupus erythematosus (SLE patients, both of which positively correlated with HIV viral load. Compared to the global 9G4-IgD--memory B cell population, the 9G4+IgD--memory fraction in HIV patients was dominated by isotype switched IgG+ B cells, but had a more prominent bias toward "IgM only" memory. HIV envelope reactivity was observed both in the 9G4+ serum antibody and 9G4+ B cell population. 9G4+ IgG serum antibody levels positively correlated (r = 0.403, p = 0.0019 with the serum HIV BNAbs. Interestingly, other serum autoantibodies commonly found in SLE (anti-dsDNA, ANA, anti-CL did not correlate with serum HIV BNAbs. 9G4-associated autoreactivity is preferentially expanded in chronic HIV infection as compared to other SLE autoreactivities. Therefore, the 9G4 system provides an effective tool to examine autoreactivity in HIV patients. Our results suggest that the development of HIV BNAbs is not merely a consequence of a general breakdown in

Many HIV-infected persons travel from temperate zones to (sub)tropical destinations. HIV-specific immigration issues, medical resources abroad and problems regarding travelling with multiple medications have to be anticipated. When prescribing immunizations and specific chemoprophylaxis, the stage of immunodeficiency as well as drug interactions with antiretrovirals and medicaments against opportunistic infections have to be taken into account. Live vaccines may be contraindicated. Immunocompromised HIV-infected travellers have a higher risk for serious courses of diseases by enteropathogens. Therefore a good information about food hygiene is important and a prescription of an antibiotic to take in case of severe diarrhea may be indicated. A new antiretroviral combination therapy should not be started immediately before travelling to the tropics. The possibility to continue an established HIV treatment during travel has to be evaluated cautiously. With good pre-travel advice the risk of severe health problems is low for most HIV-infected travellers.
Full Text Available 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.

Full Text Available Patients infected with the human immunodeficiency virus (HIV have an increased risk of cardiovascular disease due to increased inflammation and persistent immune activation. CD163 is a macrophage scavenger receptor that is involved in monocyte-macrophage activation in HIV-infected patients. CD163 interacts with TWEAK, a member of the TNF superfamily. Circulating levels of sTWEAK and sCD163 have been previously associated with cardiovascular disease, but no previous studies have fully analyzed their association with HIV.The aim of this study was to analyze circulating levels of sTWEAK and sCD163 as well as other known markers of inflammation (hsCRP, IL-6 and sTNFRII and endothelial dysfunction (sVCAM-1 and ADMA in 26 patients with HIV before and after 48 weeks of antiretroviral treatment (ART and 23 healthy subjects.Patients with HIV had reduced sTWEAK levels and increased sCD163, sVCAM-1, ADMA, hsCRP, IL-6 and sTNFRII plasma concentrations, as well as increased sCD163/sTWEAK ratio, compared with healthy subjects. Antiretroviral treatment significantly reduced the concentrations of sCD163, sVCAM-1, hsCRP and sTNFRII, although they remained elevated when compared with healthy subjects. Antiretroviral treatment had no effect on the concentrations of ADMA and sTWEAK, biomarkers associated with endothelial function. The use of protease inhibitors as part of antiretroviral therapy and the presence of HCV-HIV co-infection and/or active HIV replication attenuated the ART-mediated decrease in sCD163 plasma concentrations.HIV-infected patients showed a proatherogenic profile characterized by increased inflammatory, immune-activation and endothelial-dysfunction biomarkers that partially improved after ART. HCV-HIV co-infection and/or active HIV replication enhanced immune activation despite ART.
Full Text Available OBJECTIVE: We investigated the relationship of the Herpesviridiae with inflammation and subclinical atherosclerosis in HIV-infected patients. METHODS: Prospective study including virologically suppressed HIV-infected patients. IgG antibodies against herpesviruses, carotid intima-media thickness (cIMT, endothelial function through flow-mediated dilatation (FMD of the brachial artery, and blood atherosclerosis biomarkers (hsCRP, TNF-α, IL-6, MCP-1, MDA, sCD14, sCD163, VCAM-1, ICAM-1, D-dimer, and PAI-1 were measured. RESULTS: 136 patients with HIV viral load <200 copies/ml were included. 93.4% patients were infected with herpes simplex virus type-1, 55.9% with herpes simplex virus type-2, 97.1% with varicella-zoster virus, 65.4% with human herpesvirus-6, 91.2% with cytomegalovirus, and 99.3% with Epstein-Barr virus. Previous AIDS diagnosis was associated with higher cytomegalovirus IgG titers (23,000 vs 17,000 AU, P = 0.011 and higher varicella-zoster virus IgG titers (3.19 vs 2.88 AU, P = 0.047, and there was a positive correlation of the Framingham risk score with IgG levels against cytomegalovirus (Spearman's Rho 0.216, P = 0.016 and Herpes simplex virus-2 (Spearman's Rho 0.293, P = 0.001. IgG antibodies against cytomegalovirus correlated in adjusted analysis with the cIMT (P = 0.030. High seropositivity for varicella-zoster virus (OR 2.91, 95% CI 1.05-8.01, P = 0.039, and for cytomegalovirus (OR 3.79, 95% CI 1.20-11.97, P = 0.023 were predictors for the highest quartile of the cIMT in adjusted analyses. PAI-1 levels were independently associated with cytomegalovirus IgG titers (P = 0.041, IL-6 and ICAM-1 levels with varicella-zoster virus IgG (P = 0.046 and P = 0.035 respectively, and hsCRP levels with Herpes simplex virus-2 IgG (P = 0.035.

To examine the long-term effects of individual antiretroviral drugs on body composition among 416 persons initiating antiretroviral therapy (ART). In a substudy of a clinical trial of persons initiating ART, changes in body composition attributable to individual ART were examined. ARTs assessed were as follows: indinavir, ritonavir, nelfinavir, efavirenz, nevirapine, stavudine (d4T), zidovudine (ZDV), lamivudine (3TC), didanosine, and abacavir. Skinfolds and circumferences were measured at baseline and every 4 months. Mid arm, mid thigh, and waist subcutaneous tissue areas and nonsubcutaneous tissue areas were calculated. Rates of change per year of exposure to each individual ART drug were determined using multivariate longitudinal regression. d4T and ZDV use was associated with losses in subcutaneous tissue area and skinfold thickness. 3TC use was associated with gains in all subcutaneous tissue areas and skinfold thickness, whereas abacavir use was associated with an increase in waist subcutaneous tissue area. Indinavir was associated with gains in waist subcutaneous tissue area, whereas indinavir, efavirenz, and nevirapine were associated with increases in upper back skinfolds. d4T use was also associated with increases in all nonsubcutaneous tissue areas; 3TC use was associated with the greatest increase in waist nonsubcutaneous tissue area. In this prospective nonrandomized evaluation, the nucleoside reverse transcriptase inhibitors d4T and ZDV were associated with decreases in subcutaneous tissue areas, whereas 3TC use was associated with increased subcutaneous tissue areas and waist nonsubcutaneous tissue area.

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.

Full Text Available HIV infection has been studied by various sciences, since it articulates biological, clinical and social realities. Since the time of its appearance to the present, advances in the treatment of HIV infection have been notorious and fascinating. Antiretroviral therapy promotes an improved quality of life for patients and increases life expectancy but has had difficulties with treatment associated behaviour, i.e., adherence to treatment. The aim of this study was to evaluate the influence of psychopathological and behavioral determinants of HIV-positive patients. We have found that behavioral risk pattern exists in both genders and predominantely sexual in nature. Men are more compliant than women regarding treatment, but exhibit high levels in the hostility dimension. Indeed, in HIV infection, there's a limited perception of control over disease, which contributes to an adaptation guided by feelings of inadequacy. We underline the vulnerability in the female gender, since women had a behavioral pattern of significant risk.

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

Persons infected with HIV often have altered lipid profiles that may be affected by antiretroviral therapies (ART). Traditional lipid measurements may be insufficient to assess cardiovascular disease (CVD) risk in this population. We report results from 39 ART-naive participants in a substudy of A5248, a single-arm study of raltegravir, emtricitabine/tenofovir administration. Samples were collected at baseline, 12, 24 and 48 weeks after ART initiation. We performed advanced lipid phenotyping using nuclear magnetic resonance spectroscopy (Liposcience, Raleigh, NC, USA) for lipid particle size and number, and examined high-density lipoprotein (HDL) function measuring reverse cholesterol transport using J774 macrophages. We report significant increases in total cholesterol (13 mg/dl; PLDL; 8 mg/dl; P=0.03), with no change in triglycerides and without an increase in LDL particle number (P>0.1 all time points). HDL levels were increased over baseline levels at all time points (PLDL (oxLDL) levels decreased by week 12, but rose subsequently, and were not different from baseline at later time points. HDL increases were associated with increases in beneficial HDL particles and HDL cholesterol efflux capacity, which may reduce future CVD events. Persistent inflammation in these HIV+ participants, may be a cause or consequence of oxLDL levels, and may contribute to declining levels of HDL over time. Clinicaltrials.gov NCT00660972.

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

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.

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.

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.

This study aimed to examine cognitive function in acute/early HIV infection over the subsequent 2 years. Fifty-six HIV+ subjects and 21 seronegative participants of the Chicago Early HIV Infection Study were evaluated using a comprehensive neuropsychological assessment at study enrollment and at 2-year follow-up. Cognitive performance measures were compared in the groups using t tests and mixed-effect models. Patterns of relationship with clinical measures were determined between cognitive function and clinical status markers using Spearman's correlations. At the initial timepoint, the HIV group demonstrated significantly weaker performance on measures of verbal memory, visual memory, psychomotor speed, motor speed, and executive function. A similar pattern was found when cognitive function was examined at follow-up and across both timepoints. The HIV subjects had generally weaker performance on psychomotor speed, executive function, motor speed, visual memory, and verbal memory. The rate of decline in cognitive function across the 2-year follow-up period did not differ between groups. Correlations between clinical status markers and cognitive function at both timepoints showed weaker performance associated with increased disease burden. Neurocognitive difficulty in chronic HIV infection may have very early onset and reflect consequences of initial brain viral invasion and neuroinflammation during the intense, uncontrolled viremia of acute HIV infection. Further characterization of the changes occurring in initial stages of infection and the risk and protective factors for cognitive function could inform new strategies for neuroprotection.

The contribution of acute HIV infection (AHI) to transmission is widely recognized, and increasing AHI diagnosis capacity can enhance HIV prevention through subsequent behavior change or intervention. We examined the impact of targeted pooled nucleic acid amplification testing (NAAT) and social marketing to increase AHI diagnosis among men who have sex with men (MSM) in Vancouver. Observational study. We implemented pooled NAAT following negative third-generation enzyme immunoassay (EIA) testing for males above 18 years in six clinics accessed by MSM, accompanied by two social marketing campaigns developed by a community gay men's health organization. We compared test volume and diagnosis rates for pre-implementation (April 2006-March 2009) and post-implementation (April 2009-March 2012) periods. After implementation, we used linear regression to examine quarterly trends and calculated diagnostic yield. After implementation, the AHI diagnosis rate significantly increased from 1.03 to 1.84 per 1000 tests, as did quarterly HIV test volumes and acute to non-acute diagnosis ratio. Of the 217 new HIV diagnoses after implementation, 54 (24.9%) were AHIs (25 detected by pooled NAAT only) for an increased diagnostic yield of 11.5%. The average number of prior negative HIV tests (past 2 years) increased significantly for newly diagnosed MSM at the six study clinics compared to other newly diagnosed MSM in British Columbia, per quarter. Targeted implementation of pooled NAAT at clinics accessed by MSM is effective in increasing AHI diagnoses compared to third-generation EIA testing. Social marketing campaigns accompanying pooled NAAT implementation may contribute to increasing AHI diagnoses and frequency of HIV testing.
Full Text Available Tobacco use is inextricably linked to a number of health risks both in the general and HIV-infected populations. There is, however, a dearth of research on effective tobacco control programs among people living with HIV, and especially among adolescents, young adults and pregnant women, groups with heightened or increased vulnerability secondary to tobacco use. Adolescents and young adults constitute a growing population of persons living with HIV infection. Early and continued tobacco use in this population living with a disease characterized by premature onset multimorbidity and chronic inflammation is of concern. Additionally, there is an increased acuity for tobacco control among HIV-infected pregnant women to reduce pregnancy morbidity and improve fetal outcome. This review will provide an important summary of current knowledge of tobacco use among HIV-infected adolescents, young adults and pregnant women. The effects of tobacco use in these specific populations will be presented and the current state of tobacco control within these populations, assessed.

Full Text Available Transcranial direct current stimulation (tDCS is a novel non-invasive neuromodulatory method that influences neuronal firing rates and activity on dopaminergic and serotoninergic circuits. TDCS has been shown to relieve Major Depressive Disorder (MDD in the general population, suggesting its potential for other vulnerable -populations with high MDD prevalence. Aims: This study evaluated l feasibility, safety, acceptability and clinical outcomes of a two-week tDCS antidepressant treatment in HIV-MDD co-diagnosed patients, and the feasibility of collecting serum and saliva for analysis of immunity-biomarkers.. Methods: Ten enrolled patients underwent baseline evaluation and started the tDCS treatment (Mon-Fri for two weeks delivered with Phoressor II 850 PM for 20 min at 2 mA at each visit, using 2 electrodes (36cm2 placed over F3 position of EEG 10-20 system and the contralateral supraorbital region. Outcome-measures were collected at baseline, after the last tDCS and two weeks later. A quantitative microarray (Ray Bio Tech Inc for TH1/TH2 cytokines was used for saliva and blood analysis. Results: Analyzable outcome-data were obtained from 8 subjects. Depression scores significantly decreased (p<.0005 after the treatment. No serious adverse events occurred. Several transient minor AEs and occasional changes of blood pressure and heart rate were noted. Mini-mental status scores remained unchanged or increased after the treatment. All subjects were highly satisfied with the protocol and treatment results and described the desire to find new treatments for HIV-MDD as motivating participation. Conclusions: F indings support feasibility and clinical potential of tDCS for HIV-MDD patients, and justify larger-sample, sham-controlled trials.

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

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

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

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

Full Text Available BACKGROUND: Hepatitis C virus (HCV emerged as sexually transmitted infection among HIV-infected men who have sex with men (MSM. We studied whether HCV circulated in identifiable high-risk MSM subcultures and performed phylogenetic analysis. METHODS: HIV-infected MSM were recruited at the sexually transmitted infections (STI outpatient clinic and a university HIV clinic in Amsterdam, the Netherlands, 2008-2009. Participants completed a detailed questionnaire and were tested for HCV antibodies and RNA, with NS5B regions sequenced for analysis of clusters. RESULTS: Among 786 participants, the median age was 43 (IQR 37-48 years, and 93 (11.8% were HCV-positive. Seropositivity was associated with belonging to subcultures identified as leather (aOR 2.60; 95% CI 1.56-4.33, rubber/lycra (aOR 2.15; 95% CI 1.10-4.21, or jeans (aOR 2.23; 95% CI 1.41-3.54. The two largest HCV-RNA monophyletic clusters were compared; MSM in cluster I (genotype 1a, n = 13 reported more partners (P = 0.037 than MSM in cluster II (genotype 4d, n = 14, but demographics, subculture characteristics and other risk behaviors did not differ significantly between the two clusters. DISCUSSION: HCV infection is associated with identifiable groups of leather/rubber/lycra/jeans subcultures among HIV-infected MSM. Separate epidemiological HCV transmission networks were not revealed. Active HCV screening and treatment within specific subcultures may reduce HCV spread among all MSM.
Full Text Available Lymphomas occur with an increased frequency in patients with Human Immunodeficiency Virus (HIV infection. These are usually high-grade immunoblastic lymphomas and primary central nervous system lymphomas. Anaplastic large cell lymphoma (ALCL is a distinct type of non-Hodgkin′s lymphoma. It is uncommon in HIV infected individuals. We describe here an uncommon presentation of this relatively rare lymphoma in the form of spinal cord compression syndrome in a young HIV infected individual.

Full Text Available BACKGROUND: Food insecurity is increasingly reported as an important barrier of patient adherence to antiretroviral therapy (ART in both resource-poor and rich settings. However, unlike in resource rich-settings, very few quantitative studies to date have investigated the association of food insecurity with patient adherence to ART in Sub-Saharan Africa. The current study examines the association between food insecurity and adherence to ART among HIV-infected adults in the Democratic Republic of Congo (DRC. METHODS AND FINDINGS: This is a cross-sectional quantitative study of patients receiving ART at three private and one public health facilities in Kinshasa, DRC. Participants were consecutively recruited into the study between April and November 2012. Adherence was measured using a combined method coupling pharmacy refill and self-reported adherence. Food insecurity was the primary predictor, and was assessed using the Household Food Insecurity Access Scale (HFIAS. Of the 898 participants recruited into the study, 512 (57% were food insecure, and 188 (20.9% were not adherent to ART. Food insecurity was significantly associated with non-adherence to ART (AOR, 2.06; CI, 1.38-3.09. We also found that perceived harmfulness of ART and psychological distress were associated respectively with increased (AOR, 1.95; CI, 1.15-3.32 and decreased (AOR, 0.31; CI, 0.11-0.83 odds of non-adherence to ART. CONCLUSION: Food insecurity is prevalent and a significant risk factor for non-adherence to ART among HIV-infected individuals in the DRC. Our findings highlight the urgent need for strategies to improve food access among HIV-infected on ART in order to ensure patient adherence to ART and ultimately the long-term success of HIV treatment in Sub-Saharan Africa.

Full Text Available Abstract Background Recent surveillance data from Bangladesh indicate rising HIV infection among intravenous drug users (IDU in the country. We suggest a likely association between HIV risk factors in this group and other groups, such as males who have sex with males (MSM. Methods Data on MSM in Bangladesh was collected and analyzed from numerous primary and secondary sources, including government ministries, non-profit health organizations, and personal communications. Results The overall prevalence of HIV in Bangladesh is relatively low, but surveillance data indicate that infection has reached significant proportions in certain high-risk groups and may soon spread to other groups, specifically MSM. Conclusion The epidemiology of HIV infection in other countries suggests that increasing rates of HIV in higher-risk populations can precede an epidemic in the general population. We review the data concerning MSM, IDU and HIV in Bangladesh from a variety of sources and propose ways to prevent HIV transmission.

Skeletal muscle (SM) mass decreases with advanced age and with disease in HIV infection. It is unknown whether age-related muscle loss is accelerated in the current era of antiretroviral therapy and which factors might contribute to muscle loss among HIV-infected adults. We hypothesized that muscle mass would be lower and decline faster in HIV-infected adults than in similar-aged controls. Whole-body (1)H-magnetic resonance imaging was used to quantify regional and total SM in 399 HIV-infected and 204 control men and women at baseline and 5 years later. Multivariable regression identified associated factors. At baseline and Year 5, total SM was lower in HIV-infected than control men. HIV-infected women were similar to control women at both time points. After adjusting for demographics, lifestyle factors, and total adipose tissue, HIV infection was associated with lower Year 5 SM in men and higher SM in women compared with controls. Average overall 5-year change in total SM was small and age related, but rate of change was similar in HIV-infected and control men and women. CD4 count and efavirenz use in HIV-infected participants were associated with increasing SM, whereas age and stavudine use were associated with decreasing SM. Muscle mass was lower in HIV-infected men compared with controls, whereas HIV-infected women had slightly higher SM than control women after multivariable adjustment. We found evidence against substantially faster SM decline in HIV infected versus similar-aged controls. SM gain was associated with increasing CD4 count, whereas stavudine use may contribute to SM loss.

At the Armed Forces Institute of Pathology, Rawalpindi, facilities for HIV screening are available since 1987. So far, 54, 170 individuals have been tested. These included 48235 blood donors, 3369 persons proceeding abroad, 561 patients of venereal diseases, 350 Lymphoma cases, 21 deportees from the UAE, 460 clinically suspected cases of AIDS, 735 persons who were worried about HIV infection and 439 family members of HIV positive cases. A total of 30 cases were positive for anti-HIV on a strict protocol, which included screening tests followed by confirmatory tests including Western blot for HIV antibodies. The mode of HIV transmission was ascertained after a detailed history of all seropostive cases. It was found that in 24 cases the virus was acquired through sexual contact with high risk persons, which was homosexual in 3, heterosexual in 17, and bisexual in 4 cases. In 4 cases, the infection was acquired through blood transfusion, one child was infected through breast feeding, whereas only in one case the exact mode of HIV transmission was unclear. Out of 30 HIV positive cases, only three cases acquired the disease within Pakistan, 20 had acquired HIV infection during their stay in the Gulf states, while few cases had it from other countries (Saudi Arabia 1, Greece 1, France 2, S E Asia 3).

Full Text Available The paper analyzes the structure of HIV-infected children who was ill with tuberculosis in the Sverdlovsk Region in 2004-2012. The incidence of tuberculosis in children aged 0 to 14 years in the Sverdlovsk Region showed a 79.4% increase in the above period due to the introduction of Russian innovative technologies for the diagnosis of this disease in children. At the same time there was a rise in both the number of HIV-infected children aged 0 to 14 years and the proportion of same-age children with late-stage HIV infection. Simultaneously, the incidence of tuberculosis in the non-HIV-infected children aged 0 to 14 years was 55.2-193.2 times lower than that in the HIV-infected children. In 2004-2014, the Sverdlovsk Region notified fewer new cases of tuberculosis among the children without HIV infection than among those with its late stages. Non-HIV-infected children of both sexes were also ill with tuberculosis less frequently than HIV-infected boys and girls. HIV-infected children 1-3 and 7-14 years of age proved to be most vulnerable to tuberculosis. Among those who fell ill with tuberculosis, there was a preponderance of patients with late-stage HIV infection; moreover, the majority (79.6% received highly active antiretroviral therapy. 63.3% of the cases were in contact with a tuberculosis patient, only every five patients had chemoprophylaxis for this disease. High-quality vaccination against tuberculosis prevented complications and bacterial excretion in children with comorbidity. Out of the clinical forms of tuberculosis in children with HIV infection, there was a predominance of primary tuberculous complex and intrathoracic lymph node tuberculosis. The latter was less common in children without HIV infection than in those with this disease; the same was true of bacterial excretion in respiratory tuberculosis.

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.

Full Text Available Type I interferons play important roles in innate immune defense. In HIV infection, type I interferons may delay disease progression by inhibiting viral replication while at the same time accelerating disease progression by contributing to chronic immune activation.To investigate the effects of type I interferons in HIV-infection, we obtained cryopreserved peripheral blood mononuclear cell samples from 10 subjects who participated in AIDS Clinical Trials Group Study 5192, a trial investigating the activity of systemic administration of IFNα for twelve weeks to patients with untreated HIV infection. Using flow cytometry, we examined changes in cell cycle status and expression of activation antigens by circulating T cells and their maturation subsets before, during and after IFNα treatment.The proportion of CD38+HLA-DR+CD8+ T cells increased from a mean of 11.7% at baseline to 24.1% after twelve weeks of interferon treatment (p = 0.006. These frequencies dropped to an average of 20.1% six weeks after the end of treatment. In contrast to CD8+ T cells, the frequencies of activated CD4+ T cells did not change with administration of type I interferon (mean percentage of CD38+DR+ cells = 2.62% at baseline and 2.17% after 12 weeks of interferon therapy. As plasma HIV levels fell with interferon therapy, this was correlated with a "paradoxical" increase in CD8+ T cell activation (p<0.001.Administration of type I interferon increased expression of the activation markers CD38 and HLA DR on CD8+ T cells but not on CD4+ T cells of HIV+ persons. These observations suggest that type I interferons may contribute to the high levels of CD8+ T cell activation that occur during HIV infection.
Cultural practices, gender inequality and inconsistent condom use increase vulnerability to HIV infection: narratives from married and cohabiting women in rural communities in Mpumalanga province, South Africa

ABSTRACT Background: Women in sub-Saharan Africa bear the brunt of the human immunodeficiency virus (HIV) epidemic, and older married women and those in cohabiting relationships are regarded as the largest HIV risk group. Although preventing HIV infection in married or stable relationships is an international HIV prevention priority, little is known about the influence of sociocultural contexts on safe-sex practice by women, particularly older women in rural communities in South Africa. Objectives: This study aimed to examine how older women in a rural patriarchal society negotiate safer sex within marital and long-term cohabitation relationships, and their perceptions and experiences of barriers that influence condom use. Methods: Focus group discussions were conducted with married and cohabiting women aged 40–60 years recruited from primary health facilities in a rural district in Mpumalanga province, South Africa. A thematic analysis approach was used to analyse the data. Results: We found that although women reported negotiating safe sex in their relationships, they dreaded the possible consequences of suggesting condom use with their partners. Many factors made negotiating safe sex complex for these women: living in a patriarchal society where women play no part in sexual decision making, the fear of possible consequences of insisting on condom use, women’s inferior social position in marital relationships, cultural practices such as bride price, and gender inequality were the main barriers to practising safer sex. Conclusions: Older married and cohabiting women dreaded negotiating safer sex in this patriarchal society where women’s subordination is legitimized. The findings suggest that the women were at high risk of HIV infection because of their inability to negotiate condom use, or to reject forced sex and non-consensual sex. There is a need for interventions targeting older married and cohabiting couples and key stakeholders within communities to

With potent antiretroviral drugs, HIV infection is becoming a chronic disease. Emergence of comorbidities, particularly cardiovascular disease (CVD) has become a leading concern for patients living with the infection. We hypothesized that the chronic and persistent inflammation and immune activation associated with HIV disease leads to accelerated aging, characterized by CVD. This will translate into higher incidence rates of CVD in HIV infected participants, when compared to HIV negative participants, after adjustment for traditional CVD risk factors. When characterized further using cardiovascular imaging, biomarkers, immunological and genetic profiles, CVD associated with HIV will show different characteristics compared to CVD in HIV-negative individuals. The Canadian HIV and Aging cohort is a prospective, controlled cohort study funded by the Canadian Institutes of Health Research. It will recruit patients living with HIV who are aged 40 years or older or have lived with HIV for 15 years or more. A control population, frequency matched for age, sex, and smoking status, will be recruited from the general population. Patients will attend study visits at baseline, year 1, 2, 5 and 8. At each study visit, data on complete medical and pharmaceutical history will be captured, along with anthropometric measures, a complete physical examination, routine blood tests and electrocardiogram. Consenting participants will also contribute blood samples to a research biobank. The primary outcome is incidence of a composite of: myocardial infarction, coronary revascularization, stroke, hospitalization for angina or congestive heart failure, revascularization or amputation for peripheral artery disease, or cardiovascular death. Preplanned secondary outcomes are all-cause mortality, incidence of the metabolic syndrome, incidence of type 2 diabetes, incidence of renal failure, incidence of abnormal bone mineral density and body fat distribution.

In 2012, Makerere University Johns - Hopkins University, and Mulago National Referral Hospital, with support from the National Institute of Health (under Grant number: NOT AI-01-023) undertook operational research at Mulago National Hospital PMTCT/PNC clinics. The study employed Peer Family Planning Champions to offer health education, counselling, and triage aimed at increasing the identification, referral and family planning (FP) uptake among HIV positive mothers attending the clinic. The Peer Champion Intervention to improve FP uptake was introduced into Mulago Hospital PMTCT/PNC clinic, Kampala Uganda. During the intervention period, peers provided additional FP counselling and education; assisted in identification and referral of HIV Positive mothers in need of FP services; and accompanied referred mothers to FP clinics. We compiled and compared the average proportions of mothers in need that were referred and took up FP in the pre-intervention (3 months), intervention (6 months), and post-intervention(3 months) periods using interrupted time series with segmented regression models with an autoregressive term of one. Overall, during the intervention, the proportion of referred mothers in need of FP increased by 30.4 percentage points (P family planning can be a valuable addition to clinic staff in limited-resource settings. The study provides additional evidence on the utilization of peer mothers in HIV care, improves health services uptake including family planning which is a common practice in many donor supported programs. It also provides evidence that may be used to advocate for policy revisions in low-income countries to include peers as support staff especially in busy clinic settings with poor services uptake.

HIV/AIDS is a major cause of pediatric morbidity and mortality, especially in Africa. The UN Joint Program on HIV/AIDS (UNAIDS) estimates that 85% of the 2.6 million children with HIV infection are from sub-Saharan Africa. About 650,000 children are living with HIV/AIDS and approximately 1000 infected infants are born every day in Africa. Since few of the 7 million infected African women have access to HIV testing and counseling, not to mention interventions such as AZT to reduce the risk of HIV transmission to their infants, the high incidence of HIV-infected children in Africa will likely continue for some time. The countries of east and southern Africa and several countries in west Africa have the highest HIV prevalence rates in the world. The development of cost-effective strategies to provide care and improve the quality of life of HIV-infected infants and children in Africa should be a priority area for increased research and support. The authors describe progress in understanding the natural history of HIV infection in African children, review strategies for managing HIV-infected children in resource-poor settings, and discuss issues of community response and counseling for children.
Full Text Available We tried to evaluate prevalence and characteristics of Iranian HIV infected patients with retinitis due to opportunistic infections. In this cross sectional study, we evaluated 106 HIV infected patients via indirect ophthalmoscopy and slit lamp examination by 90 lens to find retinitis cases. General information and results of ophthalmologic examination were analyzed. Prevalence of retinitis due to opportunistic infections was 6.6%: cytomegalovirus (CMV retinitis 1.88%, toxoplasmosis retinochoroiditis 1.88% and tuberculosis chorioretinitis 2.83%. CD4 count was higher than 50 cell/µlit in both cases with CMV retinitis. Along with increasing survival in the HIV infected patients, the prevalence of complications such as ocular manifestation due to opportunistic infections are increasing and must be more considered.

Stigma has become a gendered phenomenon that affects increasing numbers of HIV-infected women worldwide. This study examined the role of age as a possible moderator of the relationship between stigma and antiretroviral therapy adherence, CD4% and viral load among 120 HIV-infected women. A secondary analysis was conducted using data from the Keeping Healthy and Active with Risk Reduction and Medication Adherence (KHARMA) Project, an National Institutes of Health (NIH) funded randomized controlled trial to improve Antiretroviral treatment (ART) adherence and reduce risky behaviors in HIV-infected women at five clinical sites in a South-eastern city from 2005 to 2008. Stigma was measured using the Perceived Personal Stigma of Human Immunodeficiency Virus and Acquired Immune Deficiency Syndrome (HIV/AIDS) scale. Among participants stigma was negatively associated with CD4% (r =-.26, p=.02). For the 30 participants >50 years old, age was not significantly associated with viral load, stigma or CD4%, and there was no significant association between stigma and CD4% (r=.07, p=.70). These findings indicate the need for further study regarding this potential moderating effect and possible interventions to address the susceptibility of younger women to the harmful effects of stigma.
Metabolic complications including diabetes mellitus have been increasingly recognised in HIV-infected individuals since the introduction of antiretroviral therapy, particularly protease inhibitors (PIs). Pregnancy is also a risk factor for impaired glucose metabolism, and previous studies have given conflicting results regarding the contribution of PIs to impaired glucose tolerance (IGT) and gestational diabetes mellitus (GDM) in pregnant HIV-infected women.

Full Text Available Abstract Objectives HIV-infected patients are at increased risk of developing mental health symptoms, which negatively influence the treatment of the HIV-infection. Mental health problems in HIV-infected patients may affect public health. Psychopathology, including depression and substance abuse, can increase hazardous sexual behaviour and, with it, the chance of spreading HIV. Therefore, it is important to develop an optimal treatment plan for HIV-infected patients with mental health problems. The majority of HIV-infected patients in the Netherlands (almost 60% are homosexual men. The main objectives of this study were to describe the clinical and demographic characteristics of patients with HIV who seek treatment for their mental health symptoms in the Netherlands. Secondly, we tested whether HIV infected and non-infected homosexual patients with a lifetime depressive disorder differed on several mental health symptoms. Methods We compared a cohort of 196 patients who visited the outpatient clinic for HIV and Mental Health with HIV-infected patients in the general population in Amsterdam (ATHENA-study and with non-HIV infected mental health patients (NESDA-study. DSM-IV diagnoses were determined, and several self-report questionnaires were used to assess mental health symptoms. Results Depressive disorders were the most commonly occurring diagnoses in the cohort and frequent drug use was common. HIV-infected homosexual men with a depressive disorder showed no difference in depressive symptoms or sleep disturbance, compared with non-infected depressive men. However, HIV-positive patients did express more symptoms like fear, anger and guilt. Although they showed significantly more suicidal ideation, suicide attempts were not more prevalent among HIV-infected patients. Finally, the HIV-infected depressive patients displayed a considerably higher level of drug use than the HIV-negative group. Conclusion Habitual drug use is a risk factor for

Plasmacytoid dendritic cells (pDCs) are a unique dendritic cell subset that are specialized in type I interferon (IFN) production. pDCs are key players in the antiviral immune response and serve as bridge between innate and adaptive immunity. Although pDCs do not represent the main reservoir of the Human Immunodeficiency Virus (HIV), they are a crucial subset in HIV infection as they influence viral transmission, target cell infection and antigen presentation. pDCs act as inflammatory and immunosuppressive cells, thus contributing to HIV disease progression. This review provides a state of art analysis of the interactions between HIV and pDCs and their potential roles in HIV transmission, chronic immune activation and immunosuppression. A thorough understanding of the roles of pDCs in HIV infection will help to improve therapeutic strategies to fight HIV infection, and will further increase our knowledge on this important immune cell subset.

To examine the attitudes, knowledge, and practices of Tennessee veterinarians and physicians engaged in clinical practice regarding the risk for and prevention of zoonoses in people with HIV infection or AIDS. Cross-sectional survey. Licensed Tennessee veterinarians and physicians engaged in clinical practice. A survey was mailed in January 2010 to 454 licensed veterinarians and 1,737 licensed physicians. 181 of 419 (43.20%) eligible veterinarians and 201 of 1,376 (14.61%) eligible physicians responded to the survey. A majority of both veterinarians (131/179 [73.18%]) and physicians (97/192 [50.52%]) indicated that veterinarians should always or almost always be involved in advising clients with HIV infection or AIDS. The majority of veterinarians (120/173 [69.36%]) indicated they always or almost always discussed with clients the potential risk to immune-compromised persons after diagnosing a zoonosis. A high proportion (88/94 [93.62%]) of physicians indicated they never or rarely initiated discussions about zoonoses with patients with HIV infection or AIDS. All physicians (94/94 [100%]) indicated they never or rarely contacted veterinarians for advice on zoonoses. Similarly, 174 of 180 (96.76%) veterinarians had never or rarely contacted physicians for advice on zoonoses risks. Only 25.97% of veterinarians and 33.33% of physicians were correctly able to identify zoonotic pathogens of greatest concern to people with HIV infection or AIDS. We identified several implications for veterinary medical and medical practice that may reduce zoonoses transmission risks for people with HIV infection or AIDS, including increased communication between veterinarians and physicians, increased communication between people with HIV infection or AIDS and health-care providers, increased availability of client educational materials, and increased participation in zoonoses continuing education opportunities by health-care providers.
Full Text Available Zygomycosis is an increasing threat to patients with human immunodeficiency virus (HIV infection. Zygomycosis (formerly called mucormycosis is the fungal infection with Mucor, Rhizopus, or other species that share a common morphology of large empty pauciseptate hyphae with rare random-angle branching and a collapsed “twisted ribbon” appearance. Morphology allows a specific diagnosis on frozen section or smear prior to growth and identification of the fungi in culture which makes it improtant because treatment is different than that for more common mycoses such as candidiasis and aspergillosis. We present an informative and illustrative case of zygomycosis in a patient with HIV infection and liver transplantation.

The majority of HIV-infected patients develop Candida spp-associated clinical oral lesions. Studies have shown that asymptomatic oral colonization of Candida spp may lead to oral lesions or become a source of disseminated infections. The aim of this study was to verify the effects of periodontal conditions on Candida spp prevalence and Candida spp carriage in the oral cavity of HIV-infected patients compared to non-infected patients. Twenty-five patients not infected with HIV and 48 HIV-infected patients were classified according to periodontal conditions as being periodontal healthy or with periodontal disease. Candida spp carriage and classification were performed in oral rinse samples. Viral load and CD4+ T lymphocyte (CD4+L) counts were performed in blood samples from HIV-infected patients. No differences in Candida spp prevalence related to HIV status or periodontal condition were detected. However, Candida spp carriage was increased in periodontally affected HIV-infected patients when compared to periodontally healthy HIV-infected patients (p= 0.04). Periodontally healthy HIV-infected patients presented Candida spp carriage in similar levels as healthy or periodontally affected non-HIV-infected patients. Candida spp carriage was correlated with CD4+L counting in HIV-infected patients. We concluded that periodontal disease is associated with increased Candida spp carriage in HIV-infected patients and may be a predisposing factor to clinical manifestations of candidiasis.
The Amagugu Intervention: A conceptual framework for increasing HIV disclosure and parent-led communication about health and HIV prevention among HIV-infected parents with HIV-uninfected primary school-aged children
Tamsen Jean Rochat
Full Text Available Advances in access to HIV prevention and treatment have reduced vertical transmission of HIV, with most children born to HIV-infected parents being HIV-uninfected themselves. A major challenge that HIV-infected parents face is disclosure of their HIV status to their predominantly HIV-uninfected children. Their children enter middle childhood and early adolescence facing many challenges associated with parental illness and hospitalisation, often exacerbated by stigma and a lack of access to health education and support. Increasingly, evidence suggests that primary school-aged children have the developmental capacity to grasp concepts of health and illness, including HIV, and that in the absence of parent-led communication and education about these issues, HIV-exposed children may be at increased risk of psychological and social problems. The Amagugu intervention is a six-session home-based intervention, delivered by lay counsellors, which aims to increase parenting capacity to disclose their HIV status and offer health education to their primary school-aged children. The intervention includes information and activities on disclosure, health care engagement and custody planning. An uncontrolled pre-post evaluation study with 281 families showed the intervention was feasible, acceptable and effective in increasing maternal disclosure. The aim of this manuscript is to describe the conceptual model of the Amagugu intervention, as developed post-evaluation, showing the proposed pathways of risk that Amagugu aims to disrupt through its intervention targets, mechanisms and activities; and to present a summary of results from the large scale evaluation study of Amagugu to demonstrate the acceptability and feasibility of the intervention model. This relatively low-intensity home-based intervention led to: increased HIV disclosure to children, improvements in mental health for mother and child, and improved health care engagement and custody planning for

Based on analysis of data collected from the national tuberculosis prevention program in Djibouti between 1990 and 1996, the authors analyzed the relationship between HIV infection and tuberculosis. The study cohort comprised a total of 22,000 patients including 14,000 with documented HIV infection. Although HIV infection probably worsened the situation, it was neither the only nor the main factor involved in the resurgence of tuberculosis. Demographic growth, higher population density, and increasing poverty as well as the quality of the national tuberculosis prevention program must be taken into account. The incidence of smear-negative tuberculosis was not significantly higher in HIV-infected patients (incidence of smear positive cases, > 92%). Extrapulmonary tuberculosis especially of pleural involvement was more common (15% versus 9.4%). Treatment was effective in HIV-infected patients. If directly observed (DOT) therapy was used, there was no risk of emergence of multidrug-resistant tuberculosis strains. Drug side-effects associated with the protocols used in Djibouti were not greater in HIV-infected patients. Most additional mortality observed in HIV-infected tuberculosis patients (10.5% versus 2%) was due to progression of HIV infection.

BACKGROUND: The relative impact of immune deficiency and lifestyle-related factors on risk of cancer in the HIV-infected population is controversial. We aimed to estimate the population-attributable fractions (PAFs) associated with smoking, being HIV-infected and with immune deficiency. METHODS...... of cancer associated with smoking and with being HIV-infected were 27 and 49%, respectively. For cancers not strongly related to smoking or viral infections, the PAFs associated with being HIV-infected and with immune deficiency were 0%. CONCLUSION: The risk of cancer is increased in HIV patients compared......: In a Danish, nationwide, population-based cohort study (1995-2011), incidences of cancer were compared between an HIV-infected cohort and a population-based matched cohort in analyses stratified on cancer category, smoking status and for HIV patients: low CD4 cell count. RESULTS: We included 3503 HIV patients...

The present study aimed to investigate lymphocyte mobilization from peripheral cell reservoirs in HIV-infected patients. Nine HIV-infected patients on stable highly active anti-retroviral therapy (HAART), eight treatment-naive HIV-infected patients and eight HIV- controls received a 1-h adrenaline...... infusion. The adrenaline infusion induced a three-fold increase in the concentration of lymphocytes in all three groups. All HIV-infected patients mobilized significantly higher numbers of CD8+ cells but less CD4+ cells. All subjects mobilized CD45RA+CD62L+ and CD8+CD28+ cells to a lesser extent than CD45......RO+CD45RA- and CD8+CD28-cells. Furthermore, high numbers of CD8+CD38+ cells were mobilized only in the HIV-infected patients. It was therefore predominantly T cells with an activated phenotype which were mobilized after adrenaline stimulation. It is concluded that the HIV-associated immune defect...
Objective: To investigate the correlation between plasma tenofovir (TFV concentration and certain renal function markers in HIV-infected women on TDF antiretroviral therapy (ART.These markers were also compared to a HIV-uninfected control group. Methods: HIV-infected women (n = 30 on TDF-based ART were matched with 30 controls forage and body mass index. Renal markers analysed were estimated glomerular filtration rate (eGFR, creatinine clearance (CrCl, serum creatinine, albuminuria, glucosuria, serum urea, serum uric acid, urine sodium and maximum tubular reabsorption of phosphate. Baseline eGFR and CrCl data were obtained retrospectively for the HIV-infected women. Plasma TFV was assayed using a validated HPLC-MS/MS method. Step wise regression, Mann–Whitney test, unpaired and paired t-tests were applied in the statistical analyses. Results: TFV concentration was independently associated with albuminuria (adjusted r2 = 0.339; p = 0.001 in HIV-infected women. In the adjusted (weight analysis, eGFR (p = 0.038,CrCl (p = 0.032 and albuminuria (p = 0.048 were significantly higher in HIV-infected compared to the uninfected women, but eGFR was abnormally high in HIV-infected women. Both eGFR (p < 0.001 and CrCl (p = 0.008 increased from baseline to follow-up in HIV-infected women. Conclusion: Plasma TFV concentration was associated with increased albuminuria in HIV infected women in this sub-study. Both eGFR and CrCl were increased in HIV-infected women from baseline. These findings should be confirmed in larger studies, and hyperfiltration in HIV-infected women warrants further investigation.

Retrospective study to review the admissions at the Hospital Marina Alta due to infection for HIV or its complications and look for risk factors. Clinical charts of patients admitted at the hospital from 1989 to 1996 were analyzed. From 11,932 admissions, 199 (1.7%) were due to patients with infection from HIV, resulting in the 2.4% of the total stay. The medium stays were higher (8.6 +/- 7.4 vs 6 +/- 4.5) more re-admissions (42.7% vs 25.5%) and higher mortality (11% vs 7.8%). The parasitic infestations of the nervous central system and cardiovascular were the most numerous number of admissions and also the longer stays. Throughout the years we saw a increase in the patients at the outpatient clinic with HIV infection and a paradogic decrease in the inpatient admissions, and also a decrease in the media stay and total stays. There is a decrease in the admissions at the inpatient level in contrast with a increment of the prevalence in the outpatients with HIV infection. The improved treatments, the experience of the physicians, the use of the Day Hospital and the use of the service of Home Care Hospitalization allows to keep more patients with less admissions and more outpatient visits.

Full Text Available Background: The biological mechanism of circumcision as potentiating HIV prevention is poorly understood. Foreskin microbiota has been postulated as having a potential role; however, little is known about the relationship between bacterial pathogens and circumcision in adults. Materials and Methods: We sampled the coronal sulcus of a diverse group of circumcised and uncircumcised men (n=315 from a government chest hospital and fertility clinic in Hyderabad, Andhra Pradesh, India. Genital examination was conducted on three groups of men: Group 1 - HIV infected; Group 2 - TB infected; Group 3 - control. Aerobic and anaerobic specimens were cultured according to standard clinical protocols, and results were analyzed following multivariate logistic regression models. Results: Three hundred fifteen study participants - 47.6% of Group 1, 36.5% of Group 2, and 15.9% of Group 3 - were enrolled in the study and included in all analyses. Overall 37.1% of the participants were circumcised without variation across groups (P=0.29. Smegma was observed in 18.7% of the participants with no cases observed in Group 3 (P<0.001. Gram-negative pathogens were more prevalent among study participants in Group 1 (22.7% and Group 2 (30.4% as compared with those in Group 3 (6.0% (P=0.003. In multivariate regression analysis, controlling for group, age, and presence of smegma, uncircumcised men were more likely to be colonized with gram positives [Adjusted Odds Ratio (AOR 1.9; P<0.05], gram negatives (AOR 2.4; P<0.05, or any pathogen (AOR 2.8; P<0.005. Conclusions: Uncircumcised men in this population in South India are more likely to harbor bacterial pathogens in the coronal sulcus than do their circumcised counterparts. Future studies should examine the relationship between foreskin microbiota and HIV transmission.
The burden of HIV infection among the nomadic Fulani of northern Nigeria is unknown. Migration — a way of life for this population — is known to increase the rate of HIV transmission and may limit individuals' access to treatment and care. Many of Africa's other traditional, pastoral societies are similarly affected. This paper ...
While we found a clear association between the number of years of sexual activity and HIV status among both men and women, we found that past participation in a concurrent sexual partnership increased the odds of HIV infection for men but not women.

AIDS as well as atherosclerosis are important public health problems. The longer survival among HIV-infected is associated with increased number of cardiovascular events in this population, and this association is not fully understood. To identify the frequency of subclinical atherosclerosis in HIV-infected patients compared to control subjects; to analyze associations between atherosclerosis and clinical and laboratory variables, cardiovascular risk factors, and the Framingham coronary heart disease risk score (FCRS). Prospective cross-sectional case-control study assessing the presence of subclinical atherosclerosis in 264 HIV-infected patients and 279 controls. Clinical evaluation included ultrasound examination of the carotid arteries, arterial stiffness by pulse wave velocity (PWV) and augmentation index (AIx), laboratory analysis of peripheral blood, and cardiovascular risk according to FCRS criteria. The significance level adopted in the statistical analysis was p media thickness was higher in the HIV group than in controls (p media thickness, was not associated with carotid plaque frequency, and did not alter the mechanical characteristics of the arterial system (PWV and AIx). HIV-infected patients are at increased risk of atherosclerosis in association with classical cardiovascular risk factors. Treatment with protease inhibitors does not promote functional changes in the arteries, and shows no association with increased frequency of atherosclerotic plaques in carotid arteries. The FCRS may be inappropriate for this population.

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

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

Background: Adrenal insufficiency (AI) is the most common endocrine complication among patients with AIDS/HIV infection and there are number of causes of AI in HIV patients. Human immunodeficiency virus directly as well as indirectly destroys adrenal glands. The estimates of its prevalence and severity vary. AI is the most life threatening but readily correctable endocrine complication that occurs in persons with HIV infection. This study was carried out to determine the frequency of Adrenal Insufficiency in HIV patients and their clinical features as proper diagnosis and timely treatment have been shown to improve quality of life and long-term mortality in AIDS patients. Methods: It was a cross sectional survey conducted at HIV clinic and Jinnah Allama Iqbal Institute of Diabetes and Endocrinology, Jinnah Hospital Lahore. Sixty-four HIV positive patients, both male and female, aged above 15 years were included in the study. HIV patients who had recently taken steroids, ketoconazole or rifampicin, determined on history, were excluded from the study. The data was collected on a structured proforma and analysis was performed in SPSS-21.0. Frequency and percentages for adrenal insufficiency and its characteristics were calculated. Chi-square test was used with p<0.05 as statistically significant. Results: In this study, 9 (14.06%) HIV patients were diagnosed with adrenal insufficiency, male to female ratio was 3.5:1 and AI was found statistically significantly associated with fatigue (p<0.008) and weight loss (p<0.001). Conclusion: Adrenal insufficiency was high among the patients with HIV, it was not gender specific but it was found to be associated with fatigue and weight loss. (author)

Chronic HIV infection and exposure to antiretroviral therapy compromises bone health in children and adolescents, potentially impacting their long-term quality of life. Thus, the purpose of this article is to review the most recent literature on this topic in HIV-infected children and adolescents. Recent studies continue to demonstrate bone abnormalities in HIV-infected children and adolescents, whether HIV is acquired perinatally or during adolescence. Researchers have employed new modalities, both high tech and those that can be utilized in resource-limited settings, to better assess bone health. New data suggest that this population may also be experiencing an increase incidence of fractures, and they may not acquire the same peak bone mass as their HIV-uninfected counterparts. Reassuringly, however, in-utero tenofovir exposure does not appear to have a significant impact on bone health in HIV-exposed, uninfected infants. HIV-infected children and adolescents are exposed to HIV and antiretroviral therapy for many decades starting early in life and during the most critical time for skeletal growth and bone mass accrual. Recent findings underscore the need for further research on bone in this population. Longitudinal studies are especially needed to evaluate long-term risk of osteoporosis and fracture.

"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.

-infected patients do not achieve optimal immune reconstitution despite suppression of viral replication. These patients are referred to as immunological nonresponders (INRs). INRs present with severely altered immunological functions, including malfunction and diminished production of cells within lymphopoetic...... tissue, perturbed frequencies of immune regulators such as regulatory T cells and Th17 cells, and increased immune activation, immunosenescence, and apoptosis. Importantly, INRs have an increased risk of morbidity and mortality compared to HIV-infected patients with an optimal immune reconstitution....... Additional treatment to HAART that may improve immune reconstitution has been investigated, but results thus far have proved disappointing. The reason for immunological nonresponse is incompletely understood. This paper summarizes the known and unknown factors regarding the incomplete immune reconstitution...

Innovative strategies are needed to identify and link hard-to-find persons living with HIV (PLWH) who are out of care (OOC). Project Engage, a health department-based project in Los Angeles County, used a mixed-methods approach to locate and provide linkage for PLWH who have limited contact with HIV medical and nonmedical services. Incentivized social network recruitment (SNR) and direct recruitment (DR) was used to identify eligible OOC alters for a linkage intervention that included HIV clinic selection, appointment and transportation support, reminder calls/texts, and clinic navigation. Between 2012 and 2015, 112 alters were identified using SNR (n = 74) and DR (n = 38). Most alters were male (80%), African American (38%), and gay (60%). Sizable percentages were homeless (78%), had engaged in sex work (32%) in the previous 6 months, had injected drugs (47%), were incarcerated in the previous 12 months (50%), and had only received HIV care during the previous 5 years while incarcerated (24%). SNR alters were more likely than DR alters to be African American, uninsured, unemployed, homeless, sex workers, injection drug users, recently incarcerated, and have unmet service needs. Alters linked to care within 3 (69%), 4-6 (5%), and 7-12 months (8%), and 72% were retained at 6-12 months. The percent virally suppressed increased (27% vs. 41%) and the median viral load decreased (P = 0.003) between linkage and follow-up at 6-12 months. The alternative approaches presented were effective at locating marginalized HIV-positive persons who are OOC for linkage and retention. The SNR approach was most successful at identifying alters with serious social challenges and gaps in needed medical/ancillary services.

The objective of this study was to investigate if early syphilis infection affects markers of HIV infection; CD4 T cells and viral load (VL). A retrospective study was performed on 160 HIV-positive patients (111 receiving antiretroviral therapy [ART] and 49 without ART). Early syphilis diagnosis was made in HIV patients during their follow-up at the HIV/AIDS Unit at a Greek Dermatology and Venereology Unit. The patients' blood tests were available at the time of diagnosis, as well as before and 12 weeks after early syphilis diagnosis. CD4 T cell counts and VL levels were measured. It was found that syphilis infection had a negative impact on the CD4 T cell counts in both groups, with reduced CD4 T cell counts observed in 84.6% (99/111) and 79.5% (39/49) of patients receiving and not receiving ART, respectively. After treatment for syphilis, CD4 T cell counts returned to pre-treatment levels in most patients, especially those receiving ART. There was a slight and transient VL increase. Patients receiving ART had a 27% increase in VL, compared to 71.4% among patients not receiving ART. Although the VL increase was slight (41-14,000 copies/ml) in the group under treatment, 4-5% (5/111) patients did not return to pre-treatment levels. Moreover, viral mutations associated with treatment resistance were identified in these patients. Early syphilis accelerates and complicates the progression of HIV infection. Early diagnosis and treatment of syphilis may prevent infection-associated complications in most instances. Consequently, prevention of syphilis and other sexually transmitted infections is of great importance for patients infected with HIV. © The Author(s) 2016.

Participants were recruited from a sexually transmitted disease (STD) clinic in Florida and were assessed regarding the knowledge and awareness of non-AIDS conditions associated with HIV infection. Questionnaires were administered before and after a brief information session on non-AIDS conditions associated with HIV infection. Participants included men (n = 46) and women (n = 51). Prior to the information session, at baseline, only 34% of the participants were worried about HIV infection. Most participants (82%) agreed that HIV could be treated with antiretroviral therapy (ART), while only 38% were aware that HIV-associated conditions cannot be easily treated with ART. After the information session, almost all participants reported they were concerned regarding the risk of HIV infection. High-risk patients may have limited knowledge about the consequences of HIV infection beyond the traditional AIDS-associated conditions. Increased awareness of these less known consequences of HIV infection may decrease the potential for complacency regarding acquiring HIV infection. © The Author(s) 2014.
Full Text Available BACKGROUND: Observational studies suggest that male circumcision may provide protection against HIV-1 infection. A randomized, controlled intervention trial was conducted in a general population of South Africa to test this hypothesis. METHODS AND FINDINGS: A total of 3,274 uncircumcised men, aged 18-24 y, were randomized to a control or an intervention group with follow-up visits at months 3, 12, and 21. Male circumcision was offered to the intervention group immediately after randomization and to the control group at the end of the follow-up. The grouped censored data were analyzed in intention-to-treat, univariate and multivariate, analyses, using piecewise exponential, proportional hazards models. Rate ratios (RR of HIV incidence were determined with 95% CI. Protection against HIV infection was calculated as 1 - RR. The trial was stopped at the interim analysis, and the mean (interquartile range follow-up was 18.1 mo (13.0-21.0 when the data were analyzed. There were 20 HIV infections (incidence rate = 0.85 per 100 person-years in the intervention group and 49 (2.1 per 100 person-years in the control group, corresponding to an RR of 0.40 (95% CI: 0.24%-0.68%; p < 0.001. This RR corresponds to a protection of 60% (95% CI: 32%-76%. When controlling for behavioural factors, including sexual behaviour that increased slightly in the intervention group, condom use, and health-seeking behaviour, the protection was of 61% (95% CI: 34%-77%. CONCLUSION: Male circumcision provides a degree of protection against acquiring HIV infection, equivalent to what a vaccine of high efficacy would have achieved. Male circumcision may provide an important way of reducing the spread of HIV infection in sub-Saharan Africa. (Preliminary and partial results were presented at the International AIDS Society 2005 Conference, on 26 July 2005, in Rio de Janeiro, Brazil..

This review will outline the multilevel effects of biological sex on HIV acquisition, pathogenesis, treatment response, and prospects for cure. Potential mechanisms will be discussed along with future research directions. HIV acquisition risk is modified by sex hormones and the vaginal microbiome, with the latter acting through both inflammation and local metabolism of pre-exposure prophylaxis drugs. Female sex associates with enhanced risk for non-AIDS morbidities including cardiovascular and cerebrovascular disease, suggesting different inflammatory profiles in men and women. Data from research on HIV cure points to sex differences in viral reservoir dynamics and a direct role for sex hormones in latency maintenance. Biological sex remains an important variable in determining the risk of HIV infection and subsequent viral pathogenesis, and emerging data suggest sex differences relevant to curative interventions. Recruitment of women in HIV clinical research is a pathway to both optimize care for women and to identify novel therapeutics for use in both men and women.

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.

Cancer is responsible for elevated HIV-related morbidity and mortality. Research on HIV-infected patients with concurrent cancer is rare in China. The purpose of our study was to investigate the prevalence and risk factors associated with cancer among HIV-infected inpatients in Beijing, and to investigate the mortality and risk factors among HIV-infected inpatients with cancer. Hospital records from a total of 1946 HIV-infected patients were collected from the Beijing Ditan Hospital. The data, from 2008 to 2013, were collected retrospectively. The cancer diagnoses included AIDS-defining cancers (ADC) and non-AIDS defining cancers (NADC). Logistic regression was used to identify risk factors predicting the concurrence of cancer with HIV. Mortality was examined using Kaplan-Meier estimates and Cox proportional hazards models. 7.7 % (149 cases) of all HIV-infected inpatients had concurrent cancer at their first hospital admission; of those, 33.6 % (50 cases) had ADCs, and 66.4 % (99 cases) had NADCs. The most prevalent NADCs were Hodgkin's lymphoma, gastrointestinal cancer, liver cancer, and lung cancer. Patients who did not accept antiretroviral therapy (ART) were more likely to suffer from cancer [AOR = 2.07 (1.42-3.01), p = 0.001]. Kaplan-Meier curves indicated that the survival probability of HIV-positive cancer patients was significantly lower than that of HIV-positive cancer-free patients (log-rank test, p cancer, the mortality was also higher among those who did not receive ART [AHR = 2.19 (1.84-2.61), p cancer concurrence among hospitalized HIV-infected patients was 7.7 %. Concurrent cancer also increased mortality among HIV-infected patients. ART was protective against concurrent cancer as well as mortality among HIV-infected cancer patients. These results highlight the importance of promoting cancer screening and early ART initiation among HIV-infected patients.

clinical definition of late presentation. The objective of this article is to present a consensus definition of late presentation of HIV infection. Methods Over the past year, two initiatives have moved towards a harmonized definition. In spring 2009, they joined efforts to identify a common definition...... of what is meant by a 'late-presenting' patient. Results Two definitions were agreed upon, as follows. Late presentation: persons presenting for care with a CD4 count below 350 cells/muL or presenting with an AIDS-defining event, regardless of the CD4 cell count. Presentation with advanced HIV disease...... able to implement this definition (either on its own or alongside their own preferred definition) when reporting surveillance or research data relating to late presentation of HIV infection....

Full Text Available A signature feature of HIV infection is poor control of herpes virus infections, which reactivate from latency and cause opportunistic infections. While the general mechanism underlying this observation is deficient CD4+T-cell function, it is unknown whether increased severity of herpes virus infections is due primarily to poor immune control in latent or lytic sites of infection, or whether CD4+ immunodeficiency leads to more critical downstream deficits in humoral or cell-mediated immunologic responses. Here we compare genital shedding patterns of herpes simplex virus-2 (HSV-2 in 98 HIV infected and 98 HIV uninfected men matched on length of infection, HSV-1 serostatus and nationality. We demonstrate that high copy HSV-2 shedding is more frequent in HIV positive men, particularly in participants with CD4+ T-cell count <200/μL. Genital shedding is more frequent due to higher rate of shedding episodes, as well as a higher proportion of prolonged shedding episodes. Peak episode viral load was not found to differ between HIV infected and uninfected participants regardless of CD4+ T-cell count. We simulate a mathematical model which recapitulates these findings and identifies that rate of HSV-2 release from neural tissue increases, duration of mucosal cytolytic immune protection decreases, and cell-free viral lifespan increases in HIV infected participants. These results suggest that increased HSV-2 shedding in HIV infected persons may be caused by impaired immune function in both latent and lytic tissue compartments, with deficits in clearance of HSV-2 infected cells and extracellular virus.

: 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.
Elevated NT-pro-brain natriuretic peptide level is independently associated with all-cause mortality in HIV-infected women in the early and recent HAART eras in the Women's Interagency HIV Study cohort.

Full Text Available HIV-infected individuals are at increased risk of right and left heart dysfunction. N-terminal-pro-brain natriuretic peptide (NT-proBNP, a marker of cardiac ventricular strain and systolic dysfunction, may be associated with all-cause mortality in HIV-infected women. The aim of this study was to determine if elevated levels of NT-proBNP is associated with increased mortality in HIV-infected women.Prospective cohort study.We measured NT-proBNP in 936 HIV-infected and 387 age-matched HIV-uninfected women early (10/11/94 to 7/17/97 and 1082 HIV-infected and 448 HIV-uninfected women late (4/1/08 to 10/7/08 in the highly active antiretroviral therapy (HAART periods in the Women's Interagency HIV Study. An NT-proBNP >75th percentile was more likely in HIV-infected persons, but only statistically significant in the late period (27% vs. 21%, unadjusted p = 0.03. In HIV-infected participants, NT-proBNP>75th percentile was independently associated with worse 5-year survival in the early HAART period (HR 1.8, 95% CI 1.3-2.4, p<0.001 and remained a predictor of mortality in the late HAART period (HR 2.8, 95% CI 1.4-5.5, p = 0.002 independent of other established risk covariates (age, race/ethnicity, body mass index, smoking, hepatitis C serostatus, hypertension, renal function, and hemoglobin. NT-proBNP level was not associated with mortality in HIV-uninfected women.NT-proBNP is a novel independent marker of mortality in HIV-infected women both when HAART was first introduced and currently. As NT-proBNP is often associated with both pulmonary hypertension and left ventricular dysfunction, these findings suggest that these conditions may contribute significantly to adverse outcomes in this population, requiring further definition of causes and treatments of elevated NT-proBNP in HIV-infected women.

The factors associated with fibrosis in lymphoid tissue in long-term treated HIV-infected patients and their correlation with immune reconstitution were assessed. Tonsillar biopsies were performed in seven antiretroviral-naive patients and 29 successfully treated patients (median time on treatment, 61 months). Twenty patients received protease inhibitors-sparing regimens and nine protease inhibitor-containing regimens. Five tonsillar resections of HIV-negative individuals were used as controls. Lymphoid tissue architecture, collagen deposition (fibrosis) and the mean interfollicular CD4(+) cell count per mum were assessed. Naive and long-term treated HIV-infected patients had a higher proportion of fibrosis than did HIV-uninfected persons (P lymphoid tissue (P = 0.03) and smaller increase in peripheral CD4(+) T cells (r = -0.40, P = 0.05). The factors independently associated with fibrosis in lymphoid tissue were age (P lymphoid tissue viral load when compared with patients with undetectable lymphoid tissue viral load (median 5 vs. 12%, respectively, P = 0.017) and patients receiving a protease inhibitor-sparing vs. a protease inhibitor-containing regimen (median 8 vs. 2.5%, respectively, P = 0.04). Fibrosis in lymphoid tissue was associated with a poor reconstitution of CD4(+) T cells and long-term antiretroviral therapy did not reverse this abnormality. HIV infection, older age, a detectable level of lymphoid tissue viral load in treated patients and protease inhibitor-sparing regimens seem to favour fibrosis in lymphoid tissue.

Full Text Available HIV/AIDS surveillance data indicate that, in 2008, approximately one-fourth of all HIV infections in adults remain undiagnosed in Italy and that close to 60% of Aids diagnosed individuals discovered their seropositivity at the diagnosis of AIDS. Late diagnosis of HIV infection is associated with increased mortality and morbidity and increased cost to healthcare services. From a public health perspective, knowledge of HIV status is associated with a reduction in risk behaviour. Thus, a routine screening for HIV infection is important for both a better prognostic outcome, and control of HIV spreading in the population. In Italy there are not shared guidelines for the laboratory diagnosis. In this paper, we suggest two algorithms that can be adopted for the diagnosis of HIV infection in individuals undergoing HIV testing.

Full Text Available Abstract. The study of prednisone safety for treatment of TB mixed with HIV-infection has been conducted. Two groups of patients were compared. The first group was consisted of 88 patients who were treated by prednisone and standard tuberculosis therapy, the second group of patients presented by 45 patients received only tuberculosis medicines. It was demonstrated that in case of prednisone using (1st group the number of CD4 limphocytes increased, intoxication symptoms disappeared fast and recovery process accelerated. Increasing of cases with unfavorable course of TB and HIV-infection in patients of first group was not registered in compare with the second group. Thus, using of prednisone therapy to treat TB mixed with HIV-infection was safe, not lead to unfavorable course of TB or HIV-infection. Such kind of treatment especially important for patients with exudative reactions.

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.

Full Text Available Many HIV-infected children in sub-Saharan Africa enter care at a late stage of disease. As preparation of the child and family for antiretroviral therapy (ART can take several clinic visits, some children die prior to ART initiation. This study was undertaken to determine mortality rates and clinical predictors of mortality during the period prior to ART initiation.A prospective cohort study of HIV-infected treatment-naïve children was conducted between September 2007 and September 2010 at the HIV clinic at Macha Hospital in rural Southern Province, Zambia. HIV-infected children younger than 16 years of age who were treatment-naïve at study enrollment were eligible for analysis. Mortality rates prior to ART initiation were calculated and risk factors for mortality were evaluated.351 children were included in the study, of whom 210 (59.8% were eligible for ART at study enrollment. Among children ineligible for ART at enrollment, 6 children died (mortality rate: 0.33; 95% CI:0.15, 0.74. Among children eligible at enrollment, 21 children died before initiation of ART and their mortality rate (2.73 per 100 person-years; 95% CI:1.78, 4.18 was significantly higher than among children ineligible for ART (incidence rate ratio: 8.20; 95% CI:3.20, 24.83. In both groups, mortality was highest in the first three months of follow-up. Factors associated with mortality included younger age, anemia and lower weight-for-age z-score at study enrollment.These results underscore the need to increase efforts to identify HIV-infected children at an earlier age and stage of disease progression so they can enroll in HIV care and treatment programs prior to becoming eligible for ART and these deaths can be prevented.

To investigate the relationship between inflammatory [interleukin-6 (IL-6) and C-reactive protein (CRP)] and coagulation (D-dimer) biomarkers and cancer risk during HIV infection. A prospective cohort. HIV-infected patients on continuous antiretroviral therapy (ART) in the control arms of three randomized trials (N=5023) were included in an analysis of predictors of cancer (any type, infection-related or infection-unrelated). Hazard ratios for IL-6, CRP and D-dimer levels (log2-transformed) were calculated using Cox models stratified by trial and adjusted for demographics and CD4+ cell counts and adjusted also for all biomarkers simultaneously. To assess the possibility that biomarker levels were elevated at entry due to undiagnosed cancer, analyses were repeated excluding early cancer events (i.e. diagnosed during first 2 years of follow-up). During approximately 24,000 person-years of follow-up (PYFU), 172 patients developed cancer (70 infection-related; 102 infection-unrelated). The risk of developing cancer was associated with higher levels (per doubling) of IL-6 (hazard ratio 1.38, Passociated with cancer risk when all biomarkers were considered simultaneously. Results for infection-related and infection-unrelated cancers were similar to results for any cancer. Hazard ratios excluding 69 early cancer events were 1.31 (P=0.007), 1.14 (P=0.02) and 1.07 (P=0.49) for IL-6, CRP and D-dimer, respectively. Activated inflammation and coagulation pathways are associated with increased cancer risk during HIV infection. This association was stronger for IL-6 and persisted after excluding early cancer. Trials of interventions may be warranted to assess whether cancer risk can be reduced by lowering IL-6 levels in HIV-positive individuals.

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

Although non-AIDS defining malignancies are rapidly increasing as HIV-infected subjects live longer, little is know about the results of screening for colonic neoplasms (adenomatous polyps and adenocarcinomas) in this population. We conducted a screening colonoscopy study to determine the prevalence of colonic neoplasms in 136 asymptomatic HIV-infected subjects >or=50 years of age and 272 asymptomatic uninfected control subjects matched for age, sex, and family history of colorectal cancer. Advanced neoplasms were defined as adenomas >or=10 mm or any adenoma, regardless of size, with villous histology, high-grade dysplasia, or adenocarcinoma. The prevalence of neoplastic lesions was significantly higher in HIV-infected subjects than in control subjects (62.5% vs 41.2%, pscreening colonoscopy should be offered to HIV-infected subjects, but the age of initiation and the optimal frequency of screening require further study.

BACKGROUND: HIV-infected patients are at increased risk of myocardial infarction and arterial inflammation has been suggested as a pathophysiological explanation. We compared the uptake of 18F-fluorodeoxyglucose (FDG) by PET in four arterial regions, and factors associated with FDG uptake in well......-treated HIV-infected patients without cardiovascular disease (CVD) and healthy controls. METHODS AND RESULTS: We prospectively scanned 26 HIV-infected patients on stable antiretroviral therapy and 25 healthy volunteers with FDG PET/CT, measuring standardized uptake values (SUV) in the carotid arteries......, the ascending, descending, and abdominal aorta. We performed correlation analyses between FDG uptake and intima-media thickness (IMT), and soluble biomarkers of inflammation. We found no difference in arterial FDG uptake between the HIV-infected patients and healthy controls quantified either as mean SUVmax...

Full Text Available Cigarette smoking is widespread among HIV-infected patients, who confront increased risk of smoking-related co-morbidities. The effects of HIV infection and HIV-related variables on smoking and smoking cessation are incompletely understood. We investigated the correlates of smoking and quitting in an HIV-infected cohort using a validated natural language processor to determine smoking status.We developed and validated an algorithm using natural language processing (NLP to ascertain smoking status from electronic health record data. The algorithm was applied to records for a cohort of 3487 HIV-infected from a large health care system in Boston, USA, and 9446 uninfected control patients matched 3:1 on age, gender, race and clinical encounters. NLP was used to identify and classify smoking-related portions of free-text notes. These classifications were combined into patient-year smoking status and used to classify patients as ever versus never smokers and current smokers versus non-smokers. Generalized linear models were used to assess associations of HIV with 3 outcomes, ever smoking, current smoking, and current smoking in analyses limited to ever smokers (persistent smoking, while adjusting for demographics, cardiovascular risk factors, and psychiatric illness. Analyses were repeated within the HIV cohort, with the addition of CD4 cell count and HIV viral load to assess associations of these HIV-related factors with the smoking outcomes.Using the natural language processing algorithm to assign annual smoking status yielded sensitivity of 92.4, specificity of 86.2, and AUC of 0.89 (95% confidence interval [CI] 0.88-0.91. Ever and current smoking were more common in HIV-infected patients than controls (54% vs. 44% and 42% vs. 30%, respectively, both P<0.001. In multivariate models HIV was independently associated with ever smoking (adjusted rate ratio [ARR] 1.18, 95% CI 1.13-1.24, P <0.001, current smoking (ARR 1.33, 95% CI 1.25-1.40, P<0.001, and

Full Text Available Frailty is associated with morbidity and premature mortality among elderly HIV-uninfected adults, but the determinants and consequences of frailty in HIV-infected populations remain unclear. We evaluated the correlates of frailty, and the impact of frailty on mortality in a cohort of aging injection drug users (IDUs.Frailty was assessed using standard criteria among HIV-infected and uninfected IDUs in 6-month intervals from 2005 to 2008. Generalized linear mixed-model analyses assessed correlates of frailty. Cox proportional hazards models estimated risk for all-cause mortality.Of 1230 participants at baseline, the median age was 48 years and 29% were HIV-infected; the frailty prevalence was 12.3%. In multivariable analysis of 3,365 frailty measures, HIV-infected IDUs had an increased likelihood of frailty (OR, 1.66; 95% CI, 1.24-2.21 compared to HIV-uninfected IDUs; the association was strongest (OR, 2.37; 95% CI, 1.62-3.48 among HIV-infected IDUs with advanced HIV disease (CD4<350 cells/mm3 and detectable HIV RNA. No significant association was seen with less advanced disease. Sociodemographic factors, comorbidity, depressive symptoms, and prescription drug abuse were also independently associated with frailty. Mortality risk was increased with frailty alone (HR 2.63, 95% CI, 1.23-5.66, HIV infection alone (HR 3.29, 95% CI, 1.85-5.88, and being both HIV-infected and frail (HR, 7.06; 95%CI 3.49-14.3.Frailty was strongly associated with advanced HIV disease, but IDUs with well-controlled HIV had a similar prevalence to HIV-uninfected IDUs. Frailty was independently associated with mortality, with a marked increase in mortality risk for IDUs with both frailty and HIV infection.
Full Text Available BACKGROUND AND AIMS: Human immunodeficiency virus (HIV is associated with various mucocutaneous features, which may be the first pointer towards the existence of HIV infection. This study was done to note the different mucocutaneous lesions present in the HIV population in eastern India. METHODS: Four hundred and ten HIV seropositive patients attending the outpatient and inpatient departments were included in the study. RESULTS: Out of 410 HIV positives, 40% had mucocutaneous involvement at presentation. The mean age of the study population was 29 years and male to female ratio was 2.5:1. The common mucocutaneous morbidities included oral candidiasis (36%, dermatophytosis and gingivitis (13% each, herpes zoster (6%, herpes simplex and scabies (5% each. A striking feature, noted in 36% males, was straightening of hairs. Genital herpes was the commonest genital ulcer disease. Lesions associated with declining immunity included oral candidiasis, oral hairy leukoplakia and herpes zoster with median CD4 counts of 98, 62 and 198/ L respectively. CONCLUSION: Early recognition of mucocutaneous manifestations and associated STDs help in better management of HIV/AIDS.

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.

Full Text Available Abstract Background Surgical site infection (SSI are the third most frequently reported nosocomial infection, and the most common on surgical wards. HIV-infected patients may increase the possibility of developing SSI after surgery. There are few reported date on incidence and the preventive measures of SSI in HIV-infected patients. This study was to determine the incidence and the associated risk factors for SSI in HIV-infected patients. And we also explored the preventive measures. Methods A retrospective study of SSI was conducted in 242 HIV-infected patients including 17 patients who combined with hemophilia from October 2008 to September 2011 in Shanghai Public Health Clinical Center. SSI were classified according to Centers for Disease Control and Prevention (CDC criteria and identified by bedside surveillance and post-discharge follow-up. Data were analyzed using SPSS 16.0 statistical software (SPSS Inc., Chicago, IL. Results The SSI incidence rate was 47.5% (115 of 242; 38.4% incisional SSIs, 5.4% deep incisional SSIs and 3.7% organ/space SSIs. The SSI incidence rate was 37.9% in HIV-infected patients undergoing abdominal operation. Patients undergoing abdominal surgery with lower preoperative CD4 counts were more likely to develop SSIs. The incidence increased from 2.6% in clean wounds to 100% in dirty wounds. In the HIV-infected patients combined with hemophilia, the mean preoperative albumin and postoperative hemoglobin were found significantly lower than those in no-SSIs group (P Conclusions SSI is frequent in HIV-infected patients. And suitable perioperative management may decrease the SSIs incidence rate of HIV-infected patients.

The aim of this study was to examine, validate, and adapt measuring scales of internalized, personal, and occupational stigma developed in Africa into a Chinese context. Methods: A cross-sectional study was conducted from January to September 2015 in Kunming, People’s Republic of China. Various scales were constructed on the basis of the previous studies with modifications by experts using exploratory and confirmatory factor analyses (EFA + CFA. Validation of the new scales was done using multiple linear regression models and hypothesis testing of the factorial structure invariance. Results: The numbers of subjects recruited for the development/validation samples were 696/667 HIV-positive patients, 699/667 non-HIV patients, and 157/155 health care providers. EFA revealed a two-factor solution for internalized and personal stigma scales (guilt/blaming and being refused/refusing service, which were confirmed by CFA with reliability coefficients (r of 0.869 and 0.853, respectively. The occupational stigma scale was found to have a three-factor structure (blaming, professionalism, and egalitarianism with a reliability coefficient (r of 0.839. Higher correlations of factors in the HIV patients (r=0.537 and non-HIV patients (r=0.703 were observed in contrast to low-level correlations (r=0.231, 0.286, and 0.266 among factors

We use the tools of the random matrix theory (RMT) to investigate the statistical behavior of the evolution of human immunodeficiency virus (HIV) infection. By means of the nearest-neighbor spacing distribution we have identified four distinct regimes of the evolution of HIV infection. We verified that at the beginning of the so-called clinical latency phase the concentration of infected cells grows slowly and evolves in a correlated way. This regime is followed by another one in which the correlation is lost and that in turn leads the system to a regime in which the increase of infected cells is faster and correlated. In the final phase, the one in which acquired immunodeficiency syndrome (AIDS) is stablished, the system presents maximum correlation as demonstrated by GOE distribution.
Full Text Available Hidradenitis suppurativa (HS, a painful and chronic condition, commonly occurs in women and coincides with post-pubertal increase in sex hormones. A 13-year-old pre-pubertal HIV-infected male child presented to our clinic with a discharging right axillary lymph node swelling. The biopsy of the lesion showed features of HS. The patient was treated with oral antibiotics, oral steroids, and local antibiotic wash. Though the patient responded to this treatment, the clinical response was not adequate and the lesion recurred. Subsequently, the child was started on antiretroviral therapy (zidovudine, lamivudine, and nevirapine. Following these medications, the lesions healed and had not recurred till we last examined the child. Thus, this is a rare presentation of a known condition in an HIV-infected pre-pubertal male child, which did not respond to usual modalities of treatment and had to be treated with antiretroviral therapy.

The prevention of mother to child transmission of HIV has resulted in reduced burden of pediatric HIV-infection, but the prevalence of maternal HIV infection remains high in sub-Saharan African countries. HIV-exposed-uninfected infants have an increased risk of morbidity and mortality due to infectious diseases than HIV-unexposed infants, particularly during the first six months of life, which in part might be due to lower levels of pathogen-specific protective antibodies acquired transplacentally from their mothers. This could be mitigated by vaccinating pregnant women to boost antibody levels; although vaccine responses among HIV-infected pregnant women might differ compared to HIV-uninfected women. We reviewed studies that compared natural and vaccine-induced antibody levels to different epitopes between HIV-infected and HIV-uninfected pregnant women. Most studies reported lower baseline/pre-vaccination antibody levels in HIV-infected pregnant women, which may not be reversed by antiretroviral therapy during pregnancy. There were only few studies on vaccination of HIV-infected pregnant women, mainly on influenza virus and group B Streptococcus (GBS) vaccines. Immunogenicity studies on influenza vaccines indicated that HIV-infected pregnant women had lower vaccine induced hemagglutination inhibition antibody titers and a decreased likelihood of seroconversion compared to HIV-uninfected women; and while higher CD4+ T-lymphocyte levels were associated with better immune responses to vaccination, HIV viral load was not associated with responses. Furthermore, infants born to influenza vaccinated HIV-infected pregnant women also had lower antibody levels and a lower proportion of HIV-exposed infants had titers above the putative correlate of protection compared to HIV-unexposed infants. The immunogenicity of a CRM 197 -conjugated trivalent GBS vaccine was also lower in HIV-infected pregnant women compared to HIV-uninfected women, irrespective of CD4+ T

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.

Interpersonal psychotherapy (IPT) has demonstrated efficacy for the treatment of depression, yet little is known about its therapeutic mechanisms. As a specific treatment, IPT has been shown to directly reduce depressive symptoms, although it is unclear whether these reductions occur via interpersonal changes. Within IPT, the potential role of the working alliance, a common factor, as a predictor of depression and interpersonal changes is also unclear. Participants were 147 depressed persons living with HIV in rural communities of 28 U.S. states enrolled in a randomized clinical trial. Seventy-five patients received up to 9 sessions of telephone-administered IPT (tele-IPT) plus standard care and 72 patients received standard care only. Two models were tested; one included treatment condition (tele-IPT vs. control) and another included the working alliance as independent variables. The first model found an indirect effect whereby tele-IPT reduced depression via decreased social avoidance. There was a direct effect between tele-IPT and reduced depression. In the second model, the working alliance influenced depressive symptom relief via reductions in social avoidance. Both goal and task working alliance subscales were indirectly associated with reductions in depressive symptoms, also through reductions in social avoidance. There were no direct effects involving the working alliance. Tele-IPT's influence on depressive symptom reduction was primarily through a direct effect, whereas the influence of working alliance depression was almost entirely via an indirect effect through interpersonal problems. Study findings have implications for IPT when intervening with depressed rural people living with HIV/AIDS over the telephone. © 2017 Wiley Periodicals, Inc.

The HIV infection has been associated with an increased incidence of vascular events. Left ventricular mass (LVM) is independently associated with greater overall mortality. Various studies have shown that patients with HIV infection have higher LVM than the uninfected population. We aim to describe the distribution of LVM in an extensive series of patients with HIV infection, and the factors associated with its increase. A cross-sectional study was performed in HIV-infected patients followed in our center from 1 December 2009 to 28 February 2011. A transthoracic echocardiography (TTE) was performed in all patients who gave their consent. Demographic variables, viroimmunological status, cardiovascular risk factors, vascular risk at 10 years (VR10) and history of exposure to antiretroviral drugs were collected. LVM was considered to be the quantitative dependent variable. A univariate analysis was performed, including in the multivariate analysis those variables with P<,05. A TTE was performed in 400 patients, and the LVM was calculated in 388. Mean age was 45 years, 75.5 males. Mean LVM was 39.54g/m(2.7)(95% CI: 38.35-40.73). Age, height, body mass index, VR10, hypertension, dyslipidemia, different medications within the cardiovascular area and having taken nevirapine have been used in the history of the patient were associated to greater LVM. In the multivariate analysis, use of nevirapine in the history of the patient and VR10 remained in the model. VR10 may be associated with greater LVM. The relationship with nevirapine may respond to an indication bias. Copyright © 2012 Elsevier España, S.L. All rights reserved.

Full Text Available Exosomes are small membrane-bound vesicles secreted by cells that function to shuttle RNA and proteins between cells. To examine the role of exosomal micro RNA (miRNA during the early stage of HIV-1 infection we characterized miRNA in exosomes from HIV-infected macrophages, compared with exosomes from non-infected macrophages. Primary human monocytes from uninfected donors were differentiated to macrophages (MDM which were either mock-infected or infected with the macrophage-tropic HIV-1 BaL strain. Exosomes were recovered from culture media and separated from virus particles by centrifugation on iodixanol density gradients. The low molecular weight RNA fraction was prepared from purified exosomes. After pre-amplification, RNA was hybridized to microarrays containing probes for 1200 miRNA species of known and unknown function. We observed 48 miRNA species in both infected and uninfected MDM exosomes. Additionally, 38 miRNAs were present in infected-cell exosomes but not uninfected-cell exosomes. Of these, 13 miRNAs were upregulated in exosomes from HIV-infected cells, including 4 miRNA species that were increased by more than 10-fold. Though numerous miRNA species have been identified in HIV-infected cells, relatively little is known about miRNA content in exosomes from these cells. In the future, we plan to investigate whether the upregulated miRNA species we identified are increased in exosomes from HIV-1-positive patients.

It is generally believed that HIV infection could cause HIV-associated neurocognitive disorders (HAND) across a broad range of functional domains. Some of the most common findings are deficits in motor control. However, to date no neuroimaging studies have evaluated basic motor control in HIV-infected patients using a multimodal approach. In this study, we utilized high-resolution structural imaging and task-state functional magnetic resonance imaging (fMRI) to assess brain structure and motor function in a homogeneous cohort of HIV-infected patients. We found that HIV-infected patients had significantly reduced gray matter (GM) volume in cortical regions, which are involved in motor control, including the bilateral posterior insula cortex, premotor cortex, and supramarginal gyrus. Increased activation in bilateral posterior insula cortices was also demonstrated by patients during hand movement tasks compared with healthy controls. More importantly, the reduced GM in bilateral posterior insula cortices was spatially coincident with abnormal brain activation in HIV-infected patients. In addition, the results of partial correlation analysis indicated that GM reduction in bilateral posterior insula cortices and premotor cortices was significantly correlated with immune system deterioration. This study is the first to demonstrate spatially coincident GM reduction and abnormal activation during motor performance in HIV-infected patients. Although it remains unknown whether the brain deficits can be recovered, our findings may yield new insights into neurologic injury underlying motor dysfunction in HAND. (orig.)

Background Non-calcified coronary artery plaque (NCAP) may be an important predictor of cardiovascular events, however, few studies have directly measured NCAP in HIV-infected individuals. Methods We completed a prospective cross-sectional evaluation of NCAP and coronary calcium scores using CT angiography in HIV-infected subjects (n=26) without known coronary artery disease (CAD), but who had one or more CAD risk factor and compared them to controls matched on age, race, sex, body mass index and Framingham risk score (n=26). Results There was no difference in coronary calcium scores (114 ± 218 vs. 124 ± 298 p=0.89) or NCAP volume (65 ± 86 mm3 vs. 63 ± 82 mm3, p=0.38) between HIV-infected subjects and controls, respectively. Among HIV-infected subjects, lower CD4 count was associated with increased NCAP volume (r=-0.52, p=0.006). CD4 count remained a significant predictor of NCAP in a multivariate analysis that adjusted for age and duration of antiretroviral therapy. Conclusion Plaque burden is similar between HIV-infected and uninfected individuals when matched on traditional CAD risk factors, however immune function may mediate the development of atherosclerosis in HIV infection.

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

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.

Acquired immunodeficiency syndrome (AIDS) is a kind of acquired disease that breaks down the immune system. Human immunodeficiency virus (HIV) is the causative agent of AIDS. By the end of 2016, there were 36.7 million people living with HIV worldwide. Early diagnosis can alert infected individuals to risk behaviors in order to control HIV transmission. Infected individuals are also benefited from proper treatment and management upon early diagnosis. Thanks to the public awareness of the disease, the annual increase of new HIV infections has been slowly declining over the past decades. The advent of molecular diagnostics has allowed early detection and better management of HIV infected patients. Areas covered: In this review, the authors summarized and discussed the current and future technologies in molecular diagnosis as well as the biomarkers developed for HIV infection. Expert Commentary: A simple and rapid detection of viral load is important for patients and doctors to monitor HIV progression and antiretroviral treatment efficiency. In the near future, it is expected that new technologies such as digital PCR and CRISPR-based technology will play more important role in HIV detection and patient management.

Background/Purpose The seroincidence of human immunodeficiency virus (HIV) in Taiwan has drastically increased since 2004, particularly among injection drug users and prisoners. The major purpose of this study was to explore the prevalence and correlates of psychiatric morbidity among HIV-infected male prisoners. Methods In 2006, data were collected from all of HIV-infected male prisoners (n = 535) in seven prisons in Taiwan. This collection was performed using a self-administered, anonymous questionnaire in group settings directed by our interviewers. Psychiatric morbidity was measured using the five-item Brief Symptom Rating Scale in 535 participants, which represented an 85% response rate. After excluding incomplete data, 479 participants were included in the analysis. Results Psychiatric morbidity was present in 46% of participants. Multivariate logistic regression revealed that correlates of the five-item Brief Symptom Rating Scale defined cases included the following: being a recidivist, having poor self-rated health status, and having experienced psychiatric symptoms in one’s lifetime (e.g. significant physical pain or discomfort, depression for 2 weeks or longer, serious anxiety or tension, trouble understanding, concentrating, or remembering, and serious thoughts of suicide), with a Nagelkerke R2 equal to 0.365. Conclusion Psychiatric morbidity is prevalent among HIV-infected male prisoners. Tailored HIV/AIDS education related to mental health is therefore suggested for inclusion as part of a comprehensive HIV/AIDS training program among incarcerated populations. PMID:20434025

To assess the prevalence of dyslipidemia and lipodystrophy in Indian children receiving non-nucleoside reverse transcriptase inhibitor (NNRTI) based highly active antiretroviral therapy (HAART) and to determine the associated risk factors for the same. The present cross-sectional study was conducted at a Pediatric Clinic of a tertiary care teaching center in India, from May 2011 through December 2012. HIV infected children aged 5-15 y were enrolled if they did not have any severe disease or hospital admission within last 3 mo or receive any medications known to affect the lipid profile. Eighty-one children were on highly active antiretroviral therapy (HAART) for at least 6 mo and 16 were receiving no antiretroviral therapy (ART). Participants' sociodemographic, nutritional, clinical, and laboratory data were recorded in addition to anthropometry and evidence of lipodystrophy. Fasting lipid profile, apolipoprotein A1 and B levels were done for all the children. Among the children on highly active antiretroviral therapy (HAART), 38.3 % had dyslipidemia and 80.2 % had lipodystrophy, while 25 % antiretroviral therapy (ART) naïve HIV infected children had dyslipidemia. No clinically significant risk factors could be identified that increased the risk of dyslipidemia or lipodystrophy in children on highly active antiretroviral therapy (HAART). There is a high prevalence of dyslipidemia and lipodystrophy in Indian children with HIV infection with an imminent need to establish facilities for testing and treatment of these children for metabolic abnormalities.

Conclusions: Short-term use of thalidomide led to an intense transient increase in T cell activation and inflammation, with a decrease in the CD4+ cell count without changes to the CD8+ cell count. We confirmed that thalidomide acts in vitro as a latency reversal agent and speculate that the in vivo results obtained were due to an increase in HIV replication.

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.

PURPOSE OF REVIEW: To review recent published literature around three areas: long-term nonprogression/viral control; predictors of viral load set point/disease progression; and the potential impact of antiretroviral therapy (ART) in early HIV infection. RECENT FINDINGS: The natural course...... of untreated HIV infection varies widely with some HIV-positive individuals able to maintain high CD4 cell counts and/or suppressed viral load in the absence of ART. Although similar, the underlying mechanistic processes leading to long-term nonprogression and viral control are likely to differ. Concerted...... the immunological deterioration which would otherwise be seen in untreated HIV infection, recent studies do not address the longer term clinical benefits of ART at this very early stage. SUMMARY: A better understanding of the relative influences of viral, host, and environmental factors on the natural course of HIV...

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.

Adiponectin and leptin are adipose tissue hormones that regulate important lipid and glucose metabolic pathways. Our objective was to evaluate the interplay of these hormones described by the adiponectin/leptin ratio (ALR) in correlation to lipid and carbohydrate metabolism parameters in nondiabetic HIV-infected patients during antiretroviral therapy (ART). We enrolled consecutive nondiabetic patients with confirmed HIV infection, undergoing stable ART regimens for at least six months. Blood samples were collected and tested for immunological and virological parameters, adiponectin and leptin, fasting insulin, fasting plasma glucose, fasting triglycerides, total cholesterol, LDL cholesterol, and HDL cholesterol. ALR was computed for each patient. Resistance to insulin was assessed by calculating the Quantitative Insulin Sensitivity Check Index (QUICKI). We enrolled 87 HIV-infected persons, with a mean age of 31.7 years (range: 18-65), including 47 men (mean age = 32.8 years) and 40 women (mean age = 30.5 years). The median value of ALR was 6.8 (interquartile range - IQR = 17.1). In male patients, ALR was inversely associated with the serum level of triglycerides (R = 0.285, p = 0.05), total cholesterol (R = 0.326, p = 0.02), and LDL cholesterol (R = 0.298, p = 0.04). Also for the male cohort, an increase in ALR seemed to improve insulin sensitivity (R = 0.323, p = 0.02) and serum HDL cholesterol (R = 0.597, p = 0.01). None of these correlations were observed in HIV-infected women. Adiponectin and leptin seem to play important but different gender-specific roles in the pathogenesis of lipid and glucose metabolism of HIV-infected patients undergoing antiretroviral therapy.

Full Text Available Regulatory T cells (Treg increase in the context of HIV infection and pregnancy. We studied Treg subpopulations in HIV-infected and uninfected women during pregnancy and their relationship with inflammation, activation and cell-mediated immunity (CMI.Blood obtained from 20 HIV-infected and 18 uninfected women during early and late gestation was used to measure Treg and activated T cells (Tact by flow cytometry; plasma cytokines and inflammatory markers by ELISA and chemoluminescence; and CMI against varicella-zoster virus (VZV by lymphocyte proliferation.Compared with uninfected women, HIV-infected participants had higher frequencies of Treg subpopulations in early pregnancy, including CD4+CD25+FoxP3+%, CD8+CD25+FoxP3+%, CD4+TGFβ+% and CD4+IL10+%. In contrast, Treg frequencies were lower during late pregnancy in HIV-infected compared with uninfected women, including CD8+TGFβ+%, CD4+CTLA4+% and CD8+CTLA4+%. VZV-CMI, which was lower in HIV-infected compared with uninfected pregnant women, was inversely correlated with CD4+FoxP3+%, CD8+FoxP3+% and CD8+TGFβ+% in HIV-infected, but not in uninfected pregnant women. β₂-microglobulin, neopterin, IL1, IL4, IL8, IL10, IFNγ and TNFα plasma concentrations as well as Tact were higher in HIV-infected compared with uninfected women throughout pregnancy. In HIV-infected, but not in uninfected women, inflammatory, Th1, Th2 and regulatory cytokines increased with higher Treg%, suggesting that inflammation and regulation have a common pathophysiologic origin in the context of HIV infection. In HIV-infected and more commonly in uninfected pregnant women, higher Treg% correlated with lower Tact%. We conclude that Treg have different dynamics during pregnancy in HIV-infected and uninfected women. Higher levels of inflammatory cytokines and lower Treg% during late pregnancy in HIV-infected women may contribute to their increased incidence of maternal-fetal morbidity.

Full Text Available The Human Immunodeficiency Virus (HIV is a RNA retrovirus which causes the clinical disease termed the acquired immunodeficiency syndrome (AIDS. Mother-to-child transmission is the main source of spreading HIV infection to the child with frequency is as high as 25-30%. This may occurred because of the intrapartum maternal blood exposure, infected genital tract secretions and during breastfeeding. The right combination of ARV treatment and elective section caesarean delivery has been proved to reduce the mother-to-child transmission of HIV infection prevalence and preventing obstetric complications significantly. Consultation and follow up with specialists is highly recommended.

Little is known regarding the restoration of the specific immune response after combined antiretroviral therapy (cART) and anti-tuberculosis (TB) therapy introduction among TB-HIV patients. In this study, we examined the immune response of TB-HIV patients to Mycobacterium tuberculosis (Mtb) antigens to evaluate the response dynamics to different antigens over time. Moreover, we also evaluated the influence of two different doses of efavirenz and the factors associated with immune reconstitution. This is a longitudinal study nested in a clinical trial, where cART was initiated during the baseline visit (D0), which occurred 30 ± 10 days after the introduction of anti-TB therapy. Follow-up visits were performed at 30, 60, 90 and 180 days after cART initiation. The production of IFN-γ upon in vitro stimulation with Mtb antigens purified protein derivative (PPD), ESAT-6 and 38 kDa/CFP-10 using ELISpot was examined at baseline and follow-up visits. Sixty-one patients, all ART-naïve, were selected and included in the immune reconstitution analysis; seven (11.5%) developed Immune Reconstitution Inflammatory Syndrome (IRIS). The Mtb specific immune response was higher for the PPD antigen followed by 38 kDa/CFP-10 and increased in the first 60 days after cART initiation. In multivariate analysis, the variables independently associated with increased IFN-γ production in response to PPD antigen were CD4 + T cell counts tuberculosis, 800 mg efavirenz dose and follow-up CD4 + T cell counts. Moreover, the factors associated with the production of IFN-γ in response to 38 kDa/CFP-10 were detectable HIV viral load (VL) and CD4 + T cell counts at follow-up visits of ≥200 cells/mm 3 . These findings highlight the differences in immune response according to the specificity of the Mtb antigen, which contributes to a better understanding of TB-HIV immunopathogenesis. IFN-γ production elicited by PPD and 38 kDa/CFP-10 antigens have a greater magnitude compared to ESAT-6

In addition to the role of planning and executing movement, the cerebellum greatly contributes to cognitive process. Numerous studies have reported structural and functional abnormalities in the cerebellum for HIV-infected patients, but little is known about the altered functional connectivity of particular cerebellar subregions and the cerebrum. Therefore, this study aimed to explore the resting-state functional connectivity (rsFC) changes of the cerebellum and further analyze the relationship between the rsFC changes and the neuropsychological evaluation. The experiment involved 26 HIV-infected men with asymptomatic neurocognitive impairment (ANI) and 28 healthy controls (HC). We selected bilateral hemispheric lobule VI and lobule IX as seed regions and mapped the whole-brain rsFC for each subregion. Results revealed that right lobule VI showed significant increased rsFC with the anterior cingulate cortex (ACC) in HIV-infected subjects. In addition, the correlation analysis on HIV-infected subjects illustrated the increased rsFC was negatively correlated with the attention/working memory score. Moreover, significantly increased cerebellar rsFCs were also observed in HIV-infected patients related to right inferior frontal gyrus (IFG) and right superior medial gyrus (SMG) while decreased rsFC was just found between right lobule VI and the left hippocampus (HIP). These findings suggested that, abnormalities of cerebro-cerebellar functional connectivity might be associated with cognitive dysfunction in HIV-infected men, particularly working memory impairment. It could also be the underlying mechanism of ANI, providing further evidence for early injury in the neural substrate of HIV-infected patients.

Despite the success of antiretroviral therapy (ART), perinatally infected HIV remains a major health problem worldwide. Although advance neuroimaging studies have investigated structural brain changes in HIV-infected adults, regional gray matter (GM) and white matter (WM) volume changes have not been reported in perinatally HIV-infected adolescents and young adults. In this cross-sectional study, we investigated regional GM and WM changes in 16 HIV-infected youths receiving ART (age 17.0 ± 2.9 years) compared with age-matched 14 healthy controls (age 16.3 ± 2.3 years) using magnetic resonance imaging (MRI)-based high-resolution T1-weighted images with voxel based morphometry (VBM) analyses. White matter atrophy appeared in perinatally HIV-infected youths in brain areas including the bilateral posterior corpus callosum (CC), bilateral external capsule, bilateral ventral temporal WM, mid cerebral peduncles, and basal pons over controls. Gray matter volume increase was observed in HIV-infected youths for several regions including the left superior frontal gyrus, inferior occipital gyrus, gyrus rectus, right mid cingulum, parahippocampal gyrus, bilateral inferior temporal gyrus, and middle temporal gyrus compared with controls. Global WM and GM volumes did not differ significantly between groups. These results indicate WM injury in perinatally HIV-infected youths, but the interpretation of the GM results, which appeared as increased regional volumes, is not clear. Further longitudinal studies are needed to clarify if our results represent active ongoing brain infection or toxicity from HIV treatment resulting in neuronal cell swelling and regional increased GM volume. Our findings suggest that assessment of regional GM and WM volume changes, based on VBM procedures, may be an additional measure to assess brain integrity in HIV-infected youths and to evaluate success of current ART therapy for efficacy in the brain.

Full Text Available HIV infection — is a socially significant problem for many countries, as the infected die in an average of 10-11 years due to the immunodeficiency virus. Up to 20% of patients with AIDS lose their sight because of cytomegalovirus retinitis (CMV retinitis, which occurs in 70% of HIV-infected people. In some patients with HIV infection blindness occurs because of acute retinal necrosis of CMV etiology. The algorithm of CMV retinitis treatment in HIV-infected patients is described in modern manuals (ganciclovir, valganciclovir, foscarnet and others on the background of antiretroviral therapy, but the tactics of treatment of retinal separation in these patients is not clearly defined. It may be “wait and see”, providing conservative treatment with antiviral drugs, and the active tactics — vitreoretinal surgery. In this article the authors present their personal clinical observations of three HIV-infected patients with CMV retinitis at the age of 8 to 36 years with a detailed analysis of the clinical data and the results of the laboratory tests. In particular, the authors give their own results of intravitreal introduction of ganciclovir in patients with CMV retinitis. Given the poor prognosis for the life of these patients, the authors put a deontological question of justification of active treatment of retinal separation in AIDS patients with CMV retinitis.
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 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.

Patients with human immunodeficiency virus (HIV) infection have a statistically significant increased risk of developing cervical cancer. The expression of the human Ki-67 protein is strictly associated with cell proliferation. The purpose of our work was detection of proliferative activity in cervical squamous cancer in women with HIV infection. We investigated 24 cases (12 patients with HIV and 12 patients without HIV infection) of cervical carcinoma, where biopsy had been performed before the treatment. According to histopathological diagnoses, well-differentiated, moderately and poorly differentiated squamous cell carcinoma (7, 13 and 4 cases respectively) was determined. Mean age of women in the group with HIV infection was 32.7 years, and 38.2 years in the group without HIV infection. Detection of protein Ki-67 expression was performed with nuclear staining in the intermediate and superficial cells. The results of this work show that proliferative activity of cervical squamous cancer in women with HIV infection is characterized by a higher level of Ki-67 with averaging level for all histological types of squamous cell carcinoma 62.5±5.6% that is one and half times higher than in group without HIV infection. Depending on a histological type, expression of Ki-67 has increased from 4.7±3.8% in well-differentiated squamous cell carcinoma up to 89.2±5.1% in poorly differentiated squamous cell carcinoma for group with HIV, and from 21.3±2.4% to 79.4±3.7 in group without HIV.

Full Text Available The purpose of this study was to assess the possible correlation between Brucella and HIV infections. Iran is a country where HIV infection is expanding and Brucellosis is prevalent. In the present study, 184 HIV infected patients were assigned and for all of them HIV infection was confirmed by western blot test. In order to identify the prevalence rate of Brucella infection and systemic brucellosis in these subjects, sera samples were obtained and Brucella specific serological tests were performed to reveal antibody titers. Detailed history was taken and physical examination was carried out for all of patients. 11 (6% subjects had high titers but only 3 of them were symptomatic. Most of these subjects were injection drug user (IDU men and one was a rural woman. Considering both prevalence rates of Brucella infection (3% and symptomatic brucellosis (0.1% in Iran, our HIV positive patients show higher rates of Brucella infection and systemic brucellosis. Preserved cellular immunity of participants and retention of granulocytes activity may explain this poor association; whereas other explanations such as immunological state difference and non-overlapping geographical distribution of the 2 pathogens have been mentioned by various authors.

Review key topics and recent literature regarding reproductive health and family planning needs for HIV-infected women in Sub-Saharan Africa. Electronic searches performed in PubMed, JSTOR, and Web of Science; identified articles reviewed for inclusion. Most HIV-infected women in Sub-Saharan Africa bear children, and access to antiretroviral therapy may increase childbearing desires and/or fertility, resulting in greater need for contraception. Most contraceptive options can be safely and effectively used by HIV-infected women. Unmet need for contraception is high in this population, with 66- 92% of women reporting not wanting another child (now or ever), but only 20-43% using contraception. During pregnancy and delivery, HIV-infected women need access to prevention of mother-to-child transmission (PMTCT) services, a skilled birth attendant, and quality post-partum care to prevent HIV infection in the infant and maximize maternal health. Providers may lack resources as well as appropriate training and support to provide such services to women with HIV. Innovations in biomedical and behavioral interventions may improve reproductive healthcare for HIV-infected women, but in Sub-Saharan Africa, models of integrating HIV and PMTCT services with family planning and reproductive health services will be important to improve reproductive outcomes. HIV-infected women in Sub-Saharan Africa have myriad needs related to reproductive health, including access to high-quality family planning information and options, high-quality pregnancy care, and trained providers. Integrated services that help prevent unintended pregnancy and optimize maternal and infant health before, during and after pregnancy will both maximize limited resources as well as provide improved reproductive outcomes.

Cocaine use is prevalent among HIV-infected individuals. While cross-sectional studies suggest that cocaine users may be at increased risk for depression, long-term effects of cocaine on depressive symptoms remain unclear. This is a longitudinal study of 341 HIV-infected and uninfected men (135 cocaine users and 206 controls) ages 30-60 enrolled in the Multicenter AIDS Cohort Study during 1996-2009. The median baseline age was 41; 73% were African-American. In mixed-effects models over a median of 4.8 years of observation, cocaine use was associated with higher depressive symptoms independent of age, education level, and smoking (n = 288; p = 0.02); HIV infection modified this association (p = 0.03). Latent class mixed models were used to empirically identify distinct depressive trajectories (n = 160). In adjusted models, cocaine use was associated with threefold increased odds of membership in the class with persistent high depressive symptoms (95% confidence interval (CI) 1.38-6.69) and eightfold increased odds (95% CI (2.73-25.83) when tested among HIV-infected subjects only. Cocaine use is a risk factor for chronic depressive symptoms, particularly among HIV-infected men, highlighting the importance of integrating mental health and substance use treatments to address barriers to well-being and successful HIV-care.
Full Text Available Abstract Background HIV-infected women, particularly those with advanced disease, may have higher rates of pregnancy loss (miscarriage and stillbirth and neonatal mortality than uninfected women. Here we examine risk factors for these adverse pregnancy outcomes in a cohort of HIV-infected women in Zambia considering the impact of infant HIV status. Methods A total of 1229 HIV-infected pregnant women were enrolled (2001–2004 in Lusaka, Zambia and followed to pregnancy outcome. Live-born infants were tested for HIV by PCR at birth, 1 week and 5 weeks. Obstetric and neonatal data were collected after delivery and the rates of neonatal ( Results The ratio of miscarriage and stillbirth per 100 live-births were 3.1 and 2.6, respectively. Higher maternal plasma viral load (adjusted odds ratio [AOR] for each log10 increase in HIV RNA copies/ml = 1.90; 95% confidence interval [CI] 1.10–3.27 and being symptomatic were associated with an increased risk of stillbirth (AOR = 3.19; 95% CI 1.46–6.97, and decreasing maternal CD4 count by 100 cells/mm3 with an increased risk of miscarriage (OR = 1.25; 95% CI 1.02–1.54. The neonatal mortality rate was 4.3 per 100 increasing to 6.3 by 70 days. Intrauterine HIV infection was not associated with neonatal morality but became associated with mortality through 70 days (adjusted hazard ratio = 2.76; 95% CI 1.25–6.08. Low birth weight and cessation of breastfeeding were significant risk factors for both neonatal and early mortality independent of infant HIV infection. Conclusions More advanced maternal HIV disease was associated with adverse pregnancy outcomes. Excess neonatal mortality in HIV-infected women was not primarily explained by infant HIV infection but was strongly associated with low birth weight and prematurity. Intrauterine HIV infection contributed to mortality as early as 70 days of infant age. Interventions to improve pregnancy outcomes for HIV-infected women are needed to
Full Text Available Abstract Background We compared mortality by cause of death in HIV-infected adults in the era of combined antiretroviral therapy with mortality in the general population in the same age and sex groups. Methods Mortality by cause of death was analyzed for the period 1999-2006 in the cohort of persons aged 20-59 years diagnosed with HIV infection and residing in Navarre (Spain. This was compared with mortality from the same causes in the general population of the same age and sex using standardized mortality ratios (SMR. Results There were 210 deaths among 1145 persons diagnosed with HIV (29.5 per 1000 person-years. About 50% of these deaths were from AIDS. Persons diagnosed with HIV infection had exceeded all-cause mortality (SMR 14.0, 95% CI 12.2 to 16.1 and non-AIDS mortality (SMR 6.9, 5.7 to 8.5. The analysis showed excess mortality from hepatic disease (SMR 69.0, 48.1 to 78.6, drug overdose or addiction (SMR 46.0, 29.2 to 69.0, suicide (SMR 9.6, 3.8 to 19.7, cancer (SMR 3.2, 1.8 to 5.1 and cardiovascular disease (SMR 3.1, 1.3 to 6.1. Mortality in HIV-infected intravenous drug users did not change significantly between the periods 1999-2002 and 2003-2006, but it declined by 56% in non-injecting drug users (P = 0.007. Conclusions Persons with HIV infection continue to have considerable excess mortality despite the availability of effective antiretroviral treatments. However, excess mortality in the HIV patients has declined since these treatments were introduced, especially in persons without a history of intravenous drug use.

Objectives Human immunodeficiency virus (HIV)-infected children may be at risk for premature cardiovascular disease. We compared levels of biomarkers of vascular dysfunction among HIV-infected children with and without hyperlipidemia to HIV-exposed, uninfected children (HEU) enrolled in the Pediatric HIV/AIDS Cohort Study (PHACS), and determined factors associated with these biomarkers. Design Prospective cohort study Methods Biomarkers of inflammation (C-reactive protein (CRP), interleukin-6 (IL-6), and monocyte chemoattractant protein-1 (MCP1)); coagulant dysfunction (fibrinogen and P-selectin); endothelial dysfunction (soluble intracellular cell adhesion molecule-1 (sICAM), soluble vascular cell adhesion molecule-1 (sVCAM), and E-selectin); and metabolic dysfunction (adiponectin) were measured in 226 HIV-infected and 140 HEU children. Anthropometry, body composition, lipids, glucose, insulin, HIV disease severity, and antiretroviral therapy were recorded. Results The median ages were 12.3 y (HIV-infected) and 10.1 y (HEU). Body mass index (BMI) Z-scores, waist and hip circumference, and percent body fat were lower among HIV-infected. Total and non-HDL cholesterol and triglycerides were higher in HIV-infected children. HIV-infected children had higher MCP-1, fibrinogen, sICAM, and sVCAM levels. In multivariable analyses in the HIV-infected children alone, BMI z-score was associated with higher CRP and fibrinogen, but lower MCP-1 and sVCAM. Unfavorable lipid profiles were positively associated with IL6, MCP1, fibrinogen, and P- and E-selectin, whereas increased HIV viral load was associated with markers of inflammation (MCP1 and CRP) and endothelial dysfunction (sICAM and sVCAM). Conclusions HIV-infected children have higher levels of biomarkers of vascular dysfunction than do HEU children. Risk factors associated with higher biomarkers include unfavorable lipid levels and active HIV replication. PMID:22136114

Clinical observations show that the HIV infection is often associated with affections of the skin. In order to examine the involvement of the epidermal immune system in the HIV infection, we determined accessory cell function of epidermal cells from HIV-1-infected patients. For this we measured the proliferative response of enriched CD(4+)-T-lymphocytes from HIV-infected patients and noninfected controls to stimulation with anti-CD3 and IL-2 in the presence of epidermal cells; the enhancement of the response is dependent on the presence of functionally intact accessory cells. The capacity of epidermal cells to increase the anti-CD3-stimulated T-cell proliferative response was significantly enhanced in HIV patients (CDC III/IVA) as compared with noninfected donors. It is discussed, whether the increased activity of epidermal cells from HIV-infected patients may be responsible for several of the dermal lesions in the course of an HIV infection as due to an enhanced production and release of epidermal cell-derived cytokines.

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.
Full Text Available 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.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.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.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 this population

Full Text Available HIV epidemic continues to be a severe public health problem and concern within USA and across the globe with about 33 million people infected with HIV. The frequency of drug abuse among HIV infected patients is rapidly increasing and is another major issue since injection drug users are at a greater risk of developing HIV associated neurocognitive dysfunctions compared to non-drug users infected with HIV. Brain is a major target for many of the recreational drugs and HIV. Evidences suggest that opiate drug abuse is a risk factor in HIV infection, neural dysfunction and progression to AIDS. The information available on the role of morphine as a cofactor in the neuropathogenesis of HIV is scanty. This review summarizes the results that help in understanding the role of morphine use in HIV infection and neural dysfunction. Studies show that morphine enhances HIV-1 infection by suppressing IL-8, downregulating chemokines with reciprocal upregulation of HIV coreceptors. Morphine also activates MAPK signaling and downregulates cAMP response element-binding protein (CREB. Better understanding on the role of morphine in HIV infection and mechanisms through which morphine mediates its effects may help in devising novel therapeutic strategies against HIV-1 infection in opiate using HIV-infected population.

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.

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

Family and pregnancy planning are important for HIV-infected individuals and couples. There is a paucity of data regarding physician attitudes with respect to reproduction in this population, but some evidence suggests that attitudes can influence the information, advice, and services they will provide. To determine physician attitudes toward pregnancy, fertility care, and access to assisted reproductive technologies for HIV-infected individuals, and to determine whether attitudes differed based on specific physician characteristics. A survey was sent electronically to obstetrician/gynecologists and infectious disease specialists in Canada. Items were grouped into 5 key domains: physician demographics, physician attitudes toward pregnancy and adoption, physician attitudes toward fertility care, physician attitudes toward assisted reproductive technology, and challenges for an HIV-infected population. Attitudes were determined based on answers to individual questions and also for each domain. Univariate and logistic regression analyses were used to determine the influence of specific physician characteristics on attitudes. Completed surveys were received from 165 physicians. Most had positive attitudes regarding pregnancy or adoption (89%), fertility care (72%), and assisted reproductive technology (79%). In multivariate analyses, having cared for HIV-infected patients was significantly associated with having a positive attitude toward fertility care or assisted reproductive technology. In this national survey of Canadian physicians, most had positive attitudes toward pregnancy, adoption, fertility care, and use of assisted reproductive technology among HIV-infected persons. Physicians who had cared for HIV-infected individuals in the past were more likely to have positive attitudes than those who had not.

To determine mortality associated with a new cancer diagnosis in an urban, predominantly African-American, HIV-infected population. Retrospective cohort study. All HIV-infected patients diagnosed with cancer between 1 January 2000 and 30 June 2010 were reviewed. Mortality was examined using Kaplan-Meier estimates and Cox proportional hazards models. There were 470 cases of cancer among 447 patients. Patients were predominantly African-American (85%) and male (79%). Non-AIDS-defining cancers (NADCs, 69%) were more common than AIDS-defining cancers (ADCs, 31%). Cumulative cancer incidence increased significantly over the study period. The majority (55.9%) was taking antiretroviral therapy (ART) at cancer diagnosis or started afterward (26.9%); 17.2% never received ART. Stage 3 or 4 cancer was diagnosed in 67%. There were 226 deaths during 1096 person years of follow-up, yielding an overall mortality rate of 206 per 1000 person years. The cumulative mortality rate at 30 days, 1 year, and 2 years was 6.5, 32.2, and 41.4%, respectively. Mortality was similar between patients on ART whether they started before or after the cancer diagnosis but was higher in patients who never received ART. In patients with a known cause of death, 68% were related to progression of the underlying cancer. In a large cohort of urban, predominantly African-American patients with HIV and cancer, many patients presented with late-stage cancer. There was substantial 30-day and 2-year mortality, although ART had a significant mortality benefit. Deaths were most often caused by progression of cancer and not from another HIV-related or AIDS-related event.

Human immunodeficiency virus (HIV) infection is a critical problem among the incarcerated population, with rates as high as 17% being reported for prison systems in New York. The literature suggests that stressful living conditions and inherent defects in the immune system associated with HIV infection make prison populations more susceptible to a disproportionate decrease in their CD4 counts. To determine the effects of incarceration on HIV-infected individuals, the charts of 800 inmates were reviewed. Baseline (draw 1), 2- to 5-month (draw 2), and 6- to 12-month (draw 3) CD4 cell counts were obtained. Mean cell counts were calculated, and paired t-tests were used to identify differences. The group receiving antiretrovirals throughout showed no difference in mean CD4 cell count between draws 1 and 2 or between draws 1 and 3. The group not receiving HIV medications did not show a significant difference in CD4 cell counts between draws 1 and 2, but did show a significant difference between draws 1 and 3. For this group, the rate of decline in CD4 cells was greater than among an outpatient setting. The subsample of subjects initiating therapy prior to the second blood draw showed a significant increase in mean CD4 cell counts at draw 1 versus draw 2, but did not show a significant change when comparing draw 1 to draw 3. When examining subjects based on their antiviral status, the mean CD4 cell count at each of the draws was statistically associated with subjects' antiviral status. We conclude that incarceration causes a more rapid decrease in CD4 cells compared with an outpatient population, causing clinical significance on the normal course of HIV disease.
Full Text Available Abstract Background Hematological abnormalities are a common complication of HIV infection. These abnormalities increase as the disease advances. Bone marrow abnormalities occur in all stages of HIV infection. Methods Two hundred HIV infected individual were screened for hematological abnormalities from March 2007–March 2008. Absolute CD4 cell count analysis was carried out by flowcytometry. Depending on the results of the primary screening further investigations were performed, like iron studies, hemolytic work up, PNH work up and bone marrow evaluation. Other investigations included coagulation profile, urine analysis, blood culture (bacterial, fungal, mycobacterial, serology for Epstein Barr virus (EBV, Cytomegalovirus (CMV, Hepatitis B and C, and Parvo B19 infection. Results The most common hematological abnormality was anemia, seen in 65.5% (131/200 patients. Iron deficiency anemia was seen in 49.2% (/200 cases while anemia of chronic disease occurred in 50.7% (/200 cases. Bone marrow evaluation was carried out in 14 patients out of which staging marrow was performed in 2 cases of non-Hodgkin's lymphoma (NHL and did not show any bone marrow infiltration. In remaining12 cases bone marrow was done for evaluation of pancytopenia. Among patients with pancytopenia 50% (6/12 showed granulomas (4 were positive for AFB, 2 were positive for fungal cryptococci, 25% (3/12 showed hemophagocytosis. There was a strong negative correlation between anemia and CD4 counts in this study. Thrombocytopenia was seen in 7% (14/200 cases and had no significant correlation with CD4 counts. No patient had absolute neutrophil count (ANC Conclusion Anemia in HIV patients can be a good clinical indicator to predict and access the underlying immune status. Patients should be investigated for hematological manifestations and appropriate steps should be taken to identify and treat the reversible factors.

HIV infection leads to a gradual loss CD4+ T lymphocytes comprising immune competence and progression to AIDS. Effective treatment with combined antiretroviral drugs (cART) decreases viral load below detectable levels but is not able to eliminate the virus from the body. The success of cART is frustrated by the requirement of expensive life-long adherence, accumulating drug toxicities and chronic immune activation resulting in increased risk of several non-AIDS disorders, even when viral replication is suppressed. Therefore there is a strong need for therapeutic strategies as an alternative to cART. Immunotherapy, or therapeutic vaccination, aims to increase existing immune responses against HIV or induce de novo immune responses. These immune responses should provide a functional cure by controlling viral replication and preventing disease progression in the absence of cART. The key difficulty in the development of an HIV vaccine is our ignorance of the immune responses that control of viral replication, and thus how these responses can be elicited and how they can be monitored. Part one of this review provides an extensive overview of the (patho-) physiology of HIV infection. It describes the structure and replication cycle of HIV, the epidemiology and pathogenesis of HIV infection and the innate and adaptive immune responses against HIV. Part two of this review discusses therapeutic options for HIV. Prevention modalities and antiretroviral therapy are briefly touched upon, after which an extensive overview on vaccination strategies for HIV is provided, including the choice of immunogens and delivery strategies.

Full Text Available In India, acquired immunodeficiency syndrome (AIDS is a growing epidemic involving all sections of the society. Health care personnel are at increased risk of acquiring blood borne diseases like AIDS, hepatitis, etc. We aimed to assess the level of awareness of HIV infection among the paramedical staff working in a tertiary care hospital. A total number of 207 paramedical staff were asked to complete a questionnaire covering the various aspects of HIV and AIDS which was then critically reviewed. We observed that 57.54% of the staff was aware of the different aspects of HIV infection. Our results highlighted that awareness regarding the different facets of HIV varied among the nurses, lab technicians and support staff. Transmission of blood borne infections through needle stick injury is a harsh reality involving health care personnel. There is an urgent need to teach basic knowledge about HIV infection among high-risk populations.

Epidemiological studies are a key element in determining the evolution and spread of HIV infection among the world population. Knowledge of the epidemiological dynamics improves strategies for prevention and monitoring. We examined 2,272 subjects who voluntarily underwent HIV testing from January 1992 to December 2015. For each subject, an anonymous form was completed to obtain information on personal data, sexual habits and exposure to risk factors. The number of subjects undergoing the screening test has increased over the years and the average age of the tested subjects has decreased over time. The main motivation for undergoing HIV testing is unprotected sex. Although heterosexual subjects taking the test were more numerous than homosexuals in this study, an increase in the latter over time should be highlighted. Although the number of tests performed has increased over the years, the persistence of unprotected sex shows an inadequate perception of risk. Therefore, it is necessary to implement programmes to increase the general awareness of HIV infection. It is also essential to undertake constant monitoring of behaviour, risk perception and the application of the screening test via surveillance systems in order to implement effective and efficient prevention.

Since 1985, Malawi has experienced a dual epidemic of HIV and tuberculosis (TB) which has been moderated recently by the advent of antiretroviral therapy (ART). The aim of this study was to describe the association over several decades between HIV/AIDS, the scale-up of ART and TB case notifications. Aggregate data were extracted from annual reports of the National TB Control Programme, the Ministry of Health HIV Department and the National Statistics Office. ART coverage was calculated using the total HIV population as denominator (derived from UNAIDS Spectrum software). In 1970, there were no HIV-infected persons but numbers had increased to a maximum of 1.18 million by 2014. HIV prevalence reached a maximum of 10.8% in 2000, thereafter decreasing to 7.5% by 2014. Numbers alive on ART increased from 2586 in 2003 to 536 527 (coverage 45.3%) by 2014. In 1985, there were 5286 TB cases which reached a maximum of 28 234 in 2003 and then decreased to 17 723 by 2014 (37% decline from 2003). There were increases in all types of new TB between 1998-2003 which then declined by 30% for extrapulmonary TB, by 37% for new smear-positive PTB and by 50% for smear-negative PTB. Previously treated TB cases reached a maximum of 3443 in 2003 and then declined by 42% by 2014. The rise and fall of TB in Malawi between 1985 and 2014 was strongly associated with HIV infection and ART scale-up; this has implications for ending the TB epidemic in high HIV-TB burden countries. © 2015 The Authors.

Full Text Available BACKGROUND: HIV-related opportunistic infections (OIs and malignancies continued to cause morbidity and mortality in Chinese HIV-infected individuals. The objective for this study is to elucidate the prevalence and spectrums of OIs and malignancies in HIV-infected patients in the Beijing Ditan Hospital. METHODS: The evaluation of the prevalence and spectrums of OIs and malignancies was conducted by using the clinical data of 834 HIV-infected patients admitted in the Beijing Ditan hospital from January 1, 2009, to November 30, 2012. RESULTS: The prevalence and spectrums of OIs and malignancies varied contingent on geographic region, transmission routes, and CD4 levels. We found that tuberculosis was most common OI and prevalence was 32.5%, followed by candidiasis(29.3%, Pneumocystis pneumonia(PCP(22.4%, cytomegalovirus(CMV infection(21.7%, other fungal infections(16.2%, mycobacterium avium complex(MAC(11.3%, cryptococcosis(8.0%, progressive multifocal leukoencephalopathy(PML(4.4%, Cerebral Toxoplasmosis(3.5% and Penicillium marneffei infection(1.4%; while Lymphoma(2.9%, Kaposi's sarcoma(0.8% and cervix carcinoma(0.3% were emerged as common AIDS-defining malignancies. Pulmonary OI infections were the most prevalent morbidity and mortality in patients in the AIDS stage including pulmonary tuberculosis (26.6% and PCP (22.4%. CMV infection(21.7% was most common viral infection; Fungal OIs were one of most prevalent morbidity in patients in the AIDS stage, including oral candidiasis (29.3%, other fungal infection (16.2%, Cryptococcosis (8.0% and Penicillium marneffei infection (1.4%. We found the low prevalence of AIDS-defining illnesses in central neural system in this study, including progressive multifocal leukoencephalopathy (4.4%, cerebral toxoplasmosis (3.5%, tuberculosis meningitis (3.2%, cryptococcal meningitis (2.4% and CMV encephalitis (1.1%. In-hospital mortality rate was 4.3 per 100 person-years due to severe OIs, malignancies, and medical

Complications of atherosclerosis, including myocardial infarction and stroke, are the leading cause of death and disability worldwide. Recent data strongly implicate cardiovascular death as a contributor to mortality among patients with human immunodeficiency virus (HIV) infection, with evidence suggesting increased incidence of atherosclerosis among these patients. Therefore, greater understanding of atherosclerotic mechanisms and how these responses may be similar or distinct in HIV-infected patients is needed. Key concepts in atherosclerosis are reviewed, including the evidence that inflammation and abnormal metabolism are major drivers of atherosclerosis, and connected to the current literature regarding atherosclerosis in the context of HIV.
Full Text Available Gabriel Somarriba, Daniela Neri, Natasha Schaefer, Tracie L MillerDivision of Pediatric Clinical Research, Department of Pediatrics, Miller School of Medicine, University of Miami, Miami, Florida, USAAbstract: Medical advances continue to change the face of human immunodeficiency virus–acquired immunodeficiency syndrome (HIV/AIDS. As life expectancy increases, the number of people living with HIV rises, presenting new challenges for the management of a chronic condition. Aging, nutrition, and physical activity can influence outcomes in other chronic conditions, and emerging data show that each of these factors can impact viral replication and the immune system in HIV. HIV infection results in a decline of the immune system through the depletion of CD4+ T cells. From initial infection, viral replication is a continuous phenomenon. Immunosenescence, a hallmark of aging, results in an increased susceptibility to infections secondary to a delayed immune response, and this phenomenon may be increased in HIV-infected patients. Optimal nutrition is an important adjunct in the clinical care of patients with HIV. Nutritional interventions may improve the quality and span of life and symptom management, support the effectiveness of medications, and improve the patient’s resistance to infections and other disease complications by altering immunity. Moderate physical activity can improve many immune parameters, reduce the risk of acute infection, and combat metabolic abnormalities. As people with HIV age, alternative therapies such as nutrition and physical activity may complement medical management.Keywords: HIV replication, aging, diet, nutrition, exercise, immunity

With the rapid roll-out of combination antiretroviral therapy to prevent mother-to-child transmission of HIV, there is an annual increase in the number of uninfected infants born to HIV-infected women. Although the introduction of combination antiretroviral therapy has vastly improved pregnancy outcome and the health of infants born to HIV-infected women, concerns remain regarding the impact the maternal HIV infection on the pregnancy outcome and the health of HIV-exposed uninfected infants. Maternal HIV infection is associated with negative pregnancy outcomes such as low birth weight. In addition, an increased susceptibility to infections is reported in HIV-exposed uninfected infants compared with infants born to uninfected women. Studies have shown that HIV-exposure affects the maternal/fetal unit, with increase of proinflammatory cytokine produced by placental cells, as well as altered infant immune responses. These changes could provide the underlying conditions for negative pregnancy outcomes and facilitate mother-to-child transmission of HIV in the infant. Further studies are required to understand the underlying mechanisms and investigate whether these altered infant immune responses persist and have clinical consequences beyond childhood. HIV infection in pregnant women is associated with altered immune responses in HIV-infected women and their offspring with clinical consequences for pregnancy outcome and the HIV-exposed uninfected infant. Further studies are required to address the origin and long-term consequences of prenatal HIV-exposure and subsequent immune activation for infant health.

Objective This study addresses the interleukin (IL)-21 effects on resting peripheral blood NK cells in chronically HIV-infected individuals. Design The effects of IL-21 on perforin expression, proliferation, degranulation, IFN-γ production, cytotoxicity and induction of STAT phosphorylation in NK cells were determined in vitro. Methods Peripheral blood mononuclear cells from HIV-infected and healthy individuals were incubated in vitro for 6h, 24h or 5 days with IL-21 or IL-15. Percentages of perforin, IFN-γ, CD107a, NKG2D and STAT3-5 positive cells were determined within NK cell populations. K562 cells were used as target cells in NK cytotoxicity assay. Results Frequency of CD56dim cells in chronically HIV-infected individuals was diminished. Perforin expression in CD56dim and CD56bright was comparable in healthy and HIV-infected individuals. IL-15 up-regulated perforin expression primarily in CD56bright NK cells while IL-21 up-regulated perforin in both NK subsets. IL-21 and IL- 15 up-regulated CD107a and IFN-γ as well as NK cytotoxicity. IL-15 predominantly activated STAT5, while IL-21 activated STAT5 and STAT3. IL-15, but not IL-21 increased NK cell proliferation in uninfected and HIV-infected individuals. Conclusion IL-21 augments NK effector functions in chronically HIV-infected individuals and due to its perforin enhancing properties it has potential for immunotherapy or as a vaccine adjuvant.

Full Text Available HIV prevalence is rising and has been consistently higher among women in Rwanda whereas a decreasing national HIV prevalence rate in the adult population has stabilised since 2005. Factors explaining the increased vulnerability of women to HIV infection are not currently well understood. A statistical mapping at smaller geographic units and the identification of key HIV risk factors are crucial for pragmatic and more efficient interventions. The data used in this study were extracted from the 2010 Rwanda Demographic and Health Survey data for 6952 women. A full Bayesian geo-additive logistic regression model was fitted to data in order to assess the effect of key risk factors and map district-level spatial effects on the risk of HIV infection. The results showed that women who had STIs, concurrent sexual partners in the 12 months prior to the survey, a sex debut at earlier age than 19 years, were living in a woman-headed or high-economic status household were significantly associated with a higher risk of HIV infection. There was a protective effect of high HIV knowledge and perception. Women occupied in agriculture, and those residing in rural areas were also associated with lower risk of being infected. This study provides district-level maps of the variation of HIV infection among women of child-bearing age in Rwanda. The maps highlight areas where women are at a higher risk of infection; the aspect that proximate and distal factors alone could not uncover. There are distinctive geographic patterns, although statistically insignificant, of the risk of HIV infection suggesting potential effectiveness of district specific interventions. The results also suggest that changes in sexual behaviour can yield significant results in controlling HIV infection in Rwanda.

The link between HIV infection and poverty in sub-Saharan Africa (SSA) is rather complex and findings from previous studies remain inconsistent. While some argue that poverty increases vulnerability, existing empirical evidence largely support the view that wealthier men and women have higher prevalence of HIV. In this paper, we examine the association between HIV infection and urban poverty in SSA, paying particular attention to differences in risk factors of HIV infection between the urban poor and non-poor. The study is based on secondary analysis of data from the Demographic and Health Surveys from 20 countries in SSA, conducted during 2003-2008. We apply multilevel logistic regression models, allowing the urban poverty risk factor to vary across countries to establish the extent to which the observed patterns are generalizable across countries in the SSA region. The results reveal that the urban poor in SSA have significantly higher odds of HIV infection than their urban non-poor counterparts, despite poverty being associated with a significantly lower risk among rural residents. Furthermore, the gender disparity in HIV infection (i.e. the disproportionate higher risk among women) is amplified among the urban poor. The paper confirms that the public health consequence of urban poverty that has been well documented in previous studies with respect to maternal and child health outcomes does apply to the risk of HIV infection. The positive association between household wealth and HIV prevalence observed in previous studies largely reflects the situation in the rural areas where the majority of the SSA populations reside.

To determine the lung cancer incidence and survival time among HIV-infected and uninfected women and men. Two longitudinal studies of HIV infection in the United States. Data from 2549 women in the Women's Interagency HIV Study (WIHS) and 4274 men in the Multicenter AIDS Cohort Study (MACS), all with a history of cigarette smoking, were analyzed. Lung cancer incidence rates and incidence rate ratios were calculated using Poisson regression analyses. Survival time was assessed using Kaplan-Meier and Cox proportional-hazard analyses. Thirty-seven women and 23 men developed lung cancer (46 HIV-infected and 14 HIV-uninfected) during study follow-up. In multivariable analyses, the factors that were found to be independently associated with a higher lung cancer incidence rate ratios were older age, less education, 10 or more pack-years of smoking, and a prior diagnosis of AIDS pneumonia (vs. HIV-uninfected women). In an adjusted Cox model that allowed different hazard functions for each cohort, a history of injection drug use was associated with shorter survival, and a lung cancer diagnosis after 2001 was associated with longer survival. In an adjusted Cox model restricted to HIV-infected participants, nadir CD4 lymphocyte cell count less than 200 was associated with shorter survival time. Our data suggest that pulmonary damage and inflammation associated with HIV infection may be causative for the increased risk of lung cancer. Encouraging and assisting younger HIV-infected smokers to quit and to sustain cessation of smoking is imperative to reduce the lung cancer burden in this population.

Objective To compare rates of complications associated with cesarean delivery in HIV-infected and HIV-uninfected women in the United States and to investigate trends in such complications across four study cycles spanning the implementation of HAART in the United States (1995–1996, 2000–2001, 2005–2006, 2010–2011). Design The Nationwide Inpatient Sample from the Healthcare Cost and Utilization Project is the largest all-payer hospital inpatient care database in the United States; when weighted to account for the complex sampling design, nationally representative estimates are derived. After restricting the study sample to women aged 15–49 years, our study sample consisted of approximately 1 090 000 cesarean delivery hospitalizations annually. Methods Complications associated with cesarean deliveries were categorized as infection, hemorrhage, or surgical trauma, based on groups of specific International Classification of Diseases 9th revision codes. Length of hospitalization, hospital charges, and in-hospital deaths were also examined. Results The rate of complications significantly decreased during the study periods for HIV-infected and HIV-uninfected women. However, rates of infectious complications and surgical trauma associated with cesarean deliveries remained higher among HIV-infected, compared with HIV-uninfected women in 2010–2011, as did prolonged hospital stay and in-hospital deaths. Length of hospitalization decreased over time for cesarean deliveries of HIV-infected women to a greater extent compared with HIV-uninfected women. Conclusion In the United States, rates of cesarean delivery complications decreased from 1995 to 2011. However, rates of infection, surgical trauma, hospital deaths, and prolonged hospitalization are still higher among HIV-infected women. Clinicians should remain alert to this persistently increased risk of cesarean delivery complications among HIV-infected women. PMID:25574961

Full Text Available Avascular necrosis (AVN of the femoral head is an emerging complication in HIV infected patients. It has been suggested that the increased incidence of AVN in this population may be caused by an increased prevalence of predisposing factors for osteonecrosis, including protease inhibitors, hyperlipidemia, corticosteroid use, alcohol and intravenous drug abuse. The aim of this study was to assess the risk factors for avascular necrosis developing in the femoral head of HIV infected individuals. This study consisted of meta-analysis of the secondary data extracted from current literature. The selected articles allowed two study groups to be drawn up for comparison. Group 1 comprised 324 individuals infected by the HIV virus, who did not present femoral head AVN. Group 2 comprised 32 HIV positive patients, who presented femoral head AVN. The parameters used for analysis were as follows: age, gender, sexual preference, use of intravenous drugs, time of diagnosis, CD4+ cell count, use of antiretroviral agents and duration, serum cholesterol and serum triglycerides. The present study found a statistically significant association between hypertriglyceridemia, hypercholesterolemia, sexual preference and intravenous drug abuse. The authors concluded that femoral head osteonecrosis is associated with hyperlipidemia (hypercholesterolemia and hypertriglyceridemia and intravenous drug abuse. This study supports the hypothesis that protease inhibitors play a role in the development of osteonecrosis through a tendency to cause hyperlipidemia.

The number of individuals with a chronic disease increases. Better treatment options have improved chronic patients' quality of life, likely increasing their motivation for travel. This may have resulted in a change in the number of HIV-infected travelers and/or travelers with Diabetes Mellitus (DM)

Full Text Available OBJECTIVE: Little is known about the treatment outcomes of undocumented Hispanic immigrants with HIV infection. We sought to compare the treatment outcomes of undocumented and documented patients 12-months after entering HIV care. METHODS: We conducted a retrospective cohort study of antiretroviral-naive patients 18 years and older attending their first visit at Thomas Street Health Center in Houston, Texas, between 1/1/2003 and 6/30/2008. The study population of 1,620 HIV-infected adults included 186 undocumented Hispanic, 278 documented Hispanic, 986 Black, and 170 White patients. The main outcome measures were retention in care (quarter years with at least one completed HIV primary care provider visit and HIV suppression (HIV RNA <400 copies/mL, both measured 12-months after entering HIV care. RESULTS: Undocumented Hispanic patients had lower median initial CD4 cell count (132 cells/mm(3 than documented Hispanic patients (166 cells/mm(3; P = 0.186, Black patients (226 cells/mm(3; P<0.001, and White patients (264 cells/mm(3; P = 0.001. However, once in care, undocumented Hispanic patients did as well or better than their documented counterparts. One year after entering HIV care, undocumented Hispanics achieved similar rates of retention in care and HIV suppression as documented Hispanic and White patients. Of note, black patients were significantly less likely to have optimal retention in care (adjusted odds ratio [aOR] 0.65, CI = 0.45-0.94 or achieve HIV suppression (aOR 0.32, CI = 0.17-0.61 than undocumented Hispanics. CONCLUSIONS: Undocumented Hispanic persons with HIV infection enter care with more advanced disease than documented persons, suggesting testing and/or linkage to care efforts for this difficult-to-reach population need intensification. Once diagnosed, however, undocumented Hispanics have outcomes as good as or better than other racial/ethnic groups. Safety net providers for undocumented immigrants are vital for maintaining

Introduction Nephropathy in HIV-infected patients has been associated with progression to AIDS and death. The virus, several co-morbid conditions and certain medications may contribute to the development and progression of kidney disease. Methods This study analyzed data collected from HIV-infected persons enrolled in a HIV registry in Puerto Rico during January 1998 through September 2006. Demographic factors, clinical manifestations, laboratory findings at enrollment, and antiretroviral therapy (ART) prescriptions were compared between patients with and without kidney disease. Death status and cause of death by December 2006 were also evaluated and compared. Results The study included 1,283 subjects, 69.0% male, 39.7% injecting drug users, 19.5% hepatitis C infected, 6.5% with diabetes mellitus (DM-II), 11.6% had hypertension (HTN) and 9.0% had kidney disease. Patients with kidney disease had significantly higher (pPuerto Ricans HIV-infected patients with nephropathy. Kidney disease preventive strategies that include aggressive control of HIV-infection and chronic medical conditions such as hypertension and diabetes are recommend as an approach to reduce this health disparity.

Exosomes are nanovesicles released into the extracellular medium by different cell types. These vesicles carry a variety of protein and RNA cargos, and have a central role in cellular signaling and regulation. A PubMed search using the term "exosomes" finds 67 articles published in 2006. Ten years later, the same search returns approximately 1200 results for 2016 alone. The growing interest in exosomes within the scientific community reflects the different roles exerted by extracellular vesicles in biological systems and diseases. However, the increase in academic production addressing the biological function of exosomes causes much confusion, especially where the focus is on the role of exosomes in pathological situations. In this review, we critically interpret the current state of the research on exosomes and HIV infection. It is plausible to assume that exosomes influence the pathogenesis of HIV infection through their biological cargo (primarily membrane proteins and microRNAs). On the other hand, evidence for a usurpation of the exosomal budding and trafficking machinery by HIV during infection is limited, although such a mechanism cannot be ruled out. This review also discusses several biological aspects of exosomal function in the immune system. Finally, the limitations of current exosome research are pointed out. Copyright © 2017 Elsevier B.V.

Full Text Available Nontyphoidal strains of Salmonella are a leading cause of death among HIV-infected Africans. Antibody-induced complement-mediated killing protects healthy Africans against Salmonella, but increased levels of anti-lipopolysaccharide (LPS antibodies in some HIV-infected African adults block this killing. The objective was to understand how these high levels of anti-LPS antibodies interfere with the killing of Salmonella.Sera and affinity-purified antibodies from African HIV-infected adults that failed to kill invasive S. Typhimurium D23580 were compared to sera from HIV-uninfected and HIV-infected subjects with bactericidal activity. The failure of sera from certain HIV-infected subjects to kill Salmonella was found to be due to an inherent inhibitory effect of anti-LPS antibodies. This inhibition was concentration-dependent and strongly associated with IgA and IgG2 anti-LPS antibodies (p<0.0001 for both. IgG anti-LPS antibodies, from sera of HIV-infected individuals that inhibit killing at high concentration, induced killing when diluted. Conversely, IgG, from sera of HIV-uninfected adults that induce killing, inhibited killing when concentrated. IgM anti-LPS antibodies from all subjects also induced Salmonella killing. Finally, the inhibitory effect of high concentrations of anti-LPS antibodies is seen with IgM as well as IgG and IgA. No correlation was found between affinity or avidity, or complement deposition or consumption, and inhibition of killing.IgG and IgM classes of anti-S. Typhimurium LPS antibodies from HIV-infected and HIV-uninfected individuals are bactericidal, while at very high concentrations, anti-LPS antibodies of all classes inhibit in vitro killing of Salmonella. This could be due to a variety of mechanisms relating to the poor ability of IgA and IgG2 to activate complement, and deposition of complement at sites where it cannot insert in the bacterial membrane. Vaccine trials are required to understand the significance of

Non-calcified coronary artery plaque (NCAP) might be an important predictor of cardiovascular events; however, few studies have directly measured NCAP in HIV-infected individuals. We completed a prospective cross-sectional evaluation of NCAP and coronary calcium scores using computed tomography angiography in HIV-infected patients (n=26) without known coronary artery disease (CAD), but who had one or more CAD risk factor(s), and compared them with controls matched on age, race, sex, body mass index and Framingham Risk Score (n=26). There was no difference in coronary calcium scores (114 ± 218 versus 124 ± 298; P=0.89) or NCAP volume (65 ± 86 mm(3) versus 63 ± 82 mm(3); P=0.38) between HIV-infected patients and controls, respectively. Among HIV-infected patients, lower CD4(+) T-cell count was associated with increased NCAP volume (r=-0.52, P=0.006). The CD4(+) T-cell count remained a significant predictor of NCAP in a multivariate analysis that adjusted for age and duration of antiretroviral therapy. Plaque burden is similar between HIV-infected and uninfected individuals when matched on traditional CAD risk factors; however, immune function might mediate the development of atherosclerosis in HIV infection.

Objective: To determine the common hematological abnormalities in HIV infected children and any association of these abnormalities with HIV disease severity. Study Design: Cross-sectional study. Place and Duration of Study: Regional Pediatric ART centre, Medical College and Hospital, Kolkata, West Bengal, India, from November 2011 to November 2012. Methodology: Children up to 12 years with confirmed diagnosis of HIV infection were clinically examined and tested for complete hemogram and CD4 count. Bone marrow study was done in selected patient depending on hemogram report. Children were divided in different stages according to WHO clinical staging. Each of the hematological parameters was assessed for any association with progression of disease. Fisher's Exact Test was used for determining the association between WHO clinical staging and abnormal blood parameters. P-value < 0.05 was taken as significant. Results: Sixty nine percent of the study population was anemic; 47.37% (18/38), 66.67% (8/12), 71.43% (15/21) and 93.10% (27/29) of stage 1, 2, 3 and 4 respectively were anemic in the study population (p=0.001). Leucopenia was present in 34% (34/100) children. Neutropenia and lymphopenia was present in 19% (19/100) and 22% (22/100) children. Lymphopenia was present in 7.89% (3/38), 16.67% (2/12), 19.05% (4/21) and 44.83% (13/29) of patient with stage 1, 2, 3 and 4 respectively (p=0.020). Eosinophilia was present in 17% (17/100) and thrombocytopenia in 11% (11/100) children. 2 patients with stage 4 disease were with hypoplastic bone marrow. Conclusion: Anemia was the most common hematological abnormality in HIV infected children. Anemia and lymphopenia had a significant association with the stage of the disease. (author)

Full Text Available Aims and objectives: To study the frequency of thyroid, adrenal and gonadal dysfunction in newly diagnosed HIV-infected patients and to correlate them at different levels of CD4 cell counts. Materials and Methods: Forty-three HIV-positive cases were included in the study group. Cases were divided into three groups on the basis of CD4 cell count. Serum free T3, free T4, TSH, Cortisol, FSH, LH, testosterone and estradiol were estimated by the radioimmunoassay method. Hormone levels between cases were compared and their correlation with CD4 count was analyzed. Results: Prevalence of gonadal dysfunction (88.3% was the most common endocrine dysfunction followed by thyroid (60.4% and adrenal dysfunction (27.9%. Secondary hypogonadism (68.4% was more common than primary (31.6%. Low T3 syndrome, that is, isolated low free T3, was the most common (25.6% thyroid dysfunction followed by secondary hypothyroidism (16.2% and subclinical hypothyroidism (11.6%. Adrenal excess (16.3% was more common than adrenal insufficiency (11.6%. The difference in hormonal dysfunction between male and female was statistically insignificant (P > 0.05. 27.9% of patients had multiple hormone deficiency. There was negligible or no correlation between CD4 count and serum hormone level. Conclusion: In our study, endocrine dysfunction was quite common among HIV-infected patients but there was no correlation between hormone levels and CD4 count. Endocrine dysfunctions and role of hormone replacement therapy in HIV-infected patient needs to be substantiated by large longitudinal study, so that it will help to reduce morbidity, improve quality of life.

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. People who inject drugs who were knowledgeable of the

Achieving cure of HIV infection requires eliminating all replication-competent virus from the reservoir of latently infected cells or completely inhibiting infected cells from emerging from latency. Strategies include very early use of antiretroviral therapy; hematopoietic stem cell transplantation; "shock-and-kill" approaches; immune therapy with immune checkpoint inhibitors; gene therapy, including use of CC chemokine receptor 5-modified CD4+ T cells; and broadly neutralizing antibody therapy. Success is likely to require a combination of approaches. This article summarizes a presentation by Daniel C.

Analysis of the prevalence and incidence of HIV infection globally reveal striking variances with regard to continent, country, region and gender. Of the global total of 33 million people infected with HIV, approximately 65% are in sub-Saharan African countries and 15% in South and South-East Asia with the remaining 20% spread over the rest of the world. As a percentage of the population, the Caribbean at 1.1% is second only to sub-Saharan Africa (5.5%). The majority of the world's HIV is in women. Deaths from HIV are twenty-fold greater in Africa than in Europe or the USA. Individual countries in sub-Saharan Africa show huge variances in the HIV+ prevalence with most West African countries having a rate of less than 2% whilst southern African countries including Swaziland and Botswana have rates of around 25%. Environment, education and social habits all contribute to the HIV infection rates. Similar variations between countries are seen in SE Asia with Cambodia and Papua New Guinea having rates three times greater than Pakistan. One of the most striking examples of inequality is in life years added to HIV populations as a result of antiretroviral therapy. UN AIDS figures over 1996-2008 suggest an average of 2.88 added years in the USA and Europe, but only 0.1 in sub-Saharan Africa, a thirty-fold difference largely due to accessibility to ART. ART leads to a reduction in oral lesions but it is estimated that some 10 million HIV+ subjects do not have access to oral care. Thus, inequalities exist both for HIV infection and for the associated oral lesions, mainly related to ART access. HIV infection and oral mucosal lesions both appear to be related to general social determinants of health. Oral HCW must be part of mainstream healthcare teams to address these inequalities. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

With the development and widespread use of combination antiretroviral therapy, HIV-infected women live longer, healthier lives. Previous research has shown that, since the adoption of combination antiretroviral therapy in the United States, rates of morbidity and adverse obstetric outcomes remained higher for HIV-infected pregnant women compared with HIV-uninfected pregnant women. Monitoring trends in the outcomes these women experience is essential, as recommendations for this special population continue to evolve with the progress of HIV treatment and prevention options. We conducted an analysis comparing rates of hospitalizations and associated outcomes among HIV-infected and HIV-uninfected pregnant women in the United States from 2004 through 2011. We used cross-sectional hospital discharge data for girls and women age 15-49 from the 2004, 2007, and 2011 Nationwide Inpatient Sample, a nationally representative sample of US hospital discharges. Demographic characteristics, morbidity outcomes, and time trends were compared using χ(2) tests and multivariate logistic regression. Analyses were weighted to produce national estimates. In 2011, there were 4751 estimated pregnancy hospitalizations and 3855 delivery hospitalizations for HIV-infected pregnant women; neither increased since 2004. Compared with those of HIV-uninfected women, pregnancy hospitalizations of HIV-infected women were more likely to be longer, be in the South and Northeast, be covered by public insurance, and incur higher charges (all P pregnant women with HIV infection had higher rates for many adverse outcomes. Compared to 2004, hospitalizations of HIV-infected pregnant women in 2011 had higher odds of gestational diabetes (adjusted odds ratio, 1.81; 95% confidence interval, 1.16-2.84), preeclampsia/hypertensive disorders of pregnancy (adjusted odds ratio, 1.58; 95% confidence interval, 1.12-2.24), viral/mycotic/parasitic infections (adjusted odds ratio, 1.90; 95% confidence interval, 1

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

Correct and consistent condom use can prevent susceptible people from acquiring HIV infection. However, in many countries repeated cross-sectional studies reveal a trend of increasing prevalence of HIV infection alongside an increase in reported condom use. Changes in sexual behaviour that reduce the number of new HIV infections will not become apparent through changes in HIV prevalence until some time after the behaviour change takes place. Limitations in the data used to assess condom use may also explain the concurrent increases in condom use and HIV prevalence. One common indicator of condom use, the UNGASS indicator (condom use at last higher risk sex of those aged 15-24), has been chosen to illustrate how changes in the proportion of people who report using condoms do not always explain changes in the size of the group who had high risk behaviour. Indicators based on the proportion of the whole population who have sex without using a condom would be better measures of the size of the group at highest risk of HIV infection.

Full Text Available As antiretroviral therapy efficacy improves, HIV is gradually being recognized more as a chronic disease within the aging HIV-infected population. While these individuals are surviving into old age, they may, however, be experiencing "accelerated aging" with greater declines in physical function than that observed among comparably matched individuals free of HIV. This decline is not well understood and it remains unclear if physical decline correlates with the degree of immunosuppression based on CD4 lymphocyte nadir.In a cross-sectional study of accelerated aging in the older HIV-infected population on antiretroviral therapy (ART, physical performance evaluations were completed on a cohort of 107 HIV-infected subjects, age 50 years or older (with no HIV-1 RNA >200 copies/mL in the prior 12 months, and compared to reference ranges for age- and gender-matched HIV-uninfected persons. Physical performance testing consisted of four validated assessments: the 2.4-meter walk, 30-second chair stand, grip strength and 6-minute walk test.When compared to age- and gender-matched HIV-uninfected reference controls, older HIV-infected persons had diminished physical function. No correlation was found between physical function and degree of immunosuppression as determined by pre-ART CD4 nadir.Despite improved survival, HIV-infected adults on suppressive ART have diminished physical function compared to HIV-uninfected persons. The degree of HIV-associated immunosuppression does not correlate with the observed degree of physical function decline in older HIV-infected persons, suggesting the decline is mediated by other mechanisms.

Until 2013, the National Osteoporosis Foundation guidelines did not include HIV infection and highly active antiretroviral therapy as osteoporosis risk factors that should trigger dual-energy x-ray absorptiometry (DEXA) screening for low bone mineral density (BMD) in older adults, but numerous data indicate that individuals with HIV infection are at early and increased risk for osteoporosis and fracture. For this reason, experts support the use of DEXA screening for HIV-infected postmenopausal women and men older than 50 years. Factors contributing to increased risk of low BMD in individuals with HIV infection include inflammation, effects of antiretroviral therapy, and numerous patient risk factors, including vitamin D deficiency. Workup for low BMD should include assessment for fracture risk and secondary causes of low BMD, including vitamin D deficiency, hyperparathyroidism, subclinical hyperthyroidism, hypogonadism, and phosphate wasting. Bisphosphonates are the preferred treatment to prevent fracture in low BMD but are not appropriate for treating osteomalacia, which is characterized by vitamin D deficiency and phosphate wasting.

To assess whether HIV-related brain injury is progressive in persons with suppressed HIV infection. Seventy-three HIV+ virally suppressed men and 35 HIV- men, screened for psychiatric and alcohol/drug use disorders, underwent neuropsychological evaluation and proton magnetic resonance spectroscopy ( 1 H-MRS) at baseline and after and 23 ± 5 months. 1 H-MRS included brain regions known to be vulnerable to HIV and aging: frontal white matter (FWM), posterior cingulate cortex (PCC), and caudate area (CA). Major brain metabolites such as creatine (Cr: marker of cellular energy), N -acetyl aspartate (NAA: marker of neuronal integrity), choline (marker of cellular membrane turnover), glutamate/glutamine (excitatory/inhibitory neurotransmitter), and myo -Inositol (mI: marker of neuroinflammation) were calculated with reference to water signal. Neurocognitive decline was corrected for practice effect and baseline HIV-associated neurocognitive disorder (HAND) status. Across the study period, 44% had intact cognition, 42% stable HAND (including the single case that improved), 10% progressing HAND, and 4% incident HAND. When analyzing the neurochemical data per neurocognitive trajectories, we found decreasing PCC Cr in all subgroups compared with controls ( p < 0.002). In addition, relative to the HIV- group, stable HAND showed decreasing FWM Cr, incident HAND showed steep FWM Cr reduction, whereas progressing HAND had a sharply decreasing PCC NAA and reduced but stable CA NAA. When analyzing the neurochemical data at the group level (HIV+ vs HIV- groups), we found stable abnormal metabolite concentrations over the study period: decreased FWM and PCC Cr (both p < 0.001), decreased PCC NAA and CA NAA (both p < 0.05) and PCC mI increase ( p < 0.05). HIV duration and historical HAND had modest effects on metabolite changes. Our study reveals covertly active or progressing HIV-related brain injury in the majority of this virally suppressed cohort, reflecting ongoing

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. Furthermore, 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.

The extended spectrum of differential diagnosis and atypical manifestations of disorders in immunodeficient patients needs to be considered in the interpretation of CT scans. Difficulties in the differential diagnosis of focal hepatic lesions in HIV-infected patients are demonstrated in the following. Besides the relatively common findings in HIV-infection such as hepato- or hepatosplenomegalia, lymphoma, and inflammatory changes of the bowel an infection with Cryptococcus neoformans, hepatitis, and local steatosis of the liver are discussed as the rare causes for suspect computertomographic findings in the live of HIV-infected patients.

Although recent studies report a high prevalence of vitamin D deficiency in HIV-infected adults similar to that in the general population, metabolic complications of vitamin D deficiency may be worsened with HIV infection and remain insufficiently characterized. We conducted a retrospective cross-sectional cohort study to determine prevalence and correlates of vitamin D deficiency and hyperparathyroidism among HIV-infected patients attending an urban clinic. Vitamin D deficiency was defined as 25(OH)-vitamin D hyperparathyroidism as parathyroid-hormone >65 pg/ml. We used the X(2) test to compare proportions and logistic regression to assess for associations. Among 463 HIV-infected patients, the prevalence of vitamin D deficiency was 59%. The prevalence of hyperparathyroidism was 30% among patients with vitamin D deficiency, 23% among those with insufficiency, and 12% among those with sufficient vitamin D levels. Vitamin D deficiency was associated with increased odds of hyperparathyroidism. Severe vitamin D deficiency was associated with elevated alkaline phosphatase, a marker for increased bone turnover. Although efavirenz use was associated with vitamin D deficiency, and protease inhibitor use with decreased odds of vitamin D deficiency, there was no statistical difference in rates of hyperparathyroidism stratified by combination antiretroviral therapy (cART) use. Given the increased risk of osteopenia with HIV infection and cART use, vitamin D supplementation for all HIV-infected patients on cART should be prescribed in accordance with the 2011 Endocrine Society guidelines. In HIV-infected patients with severe vitamin D deficiency or hyperparathyroidism, screening for osteomalacia and osteopenia may be warranted.

The advent of new antiretroviral drugs such as protease inhibitors has generated sensible changes in morbity and mortality in HIV-infected patients. To evaluate the impact of Highly Active Antiretroviral Therapy (HAART) on the prevalence of chronic otitis media in HIV-infected pediatric population. We analyzed medical charts of 471 children aged zero to 12 years and 11 months with HIV infection from an Ambulatory of ENT and AIDS. Children were divided according to the age: 0 to 5 years and 11 months and 6 to 12 years and 11 months and classified as having chronic otitis media based on history, physical examination, audiologic and tympanometric data. Prevalence of chronic otitis media, as well as CD4+ lymphocyte count were compared between groups in use of HAART and the group without HAART. Out of 459 children, 65 (14.2%) had chronic otitis media. We observed that in children aged 0 to 5 years and 11 months who were taking HAART there was significant lower prevalence of chronic otitis media (p=0.02). The use of HAART was associated to higher mean CD4+ lymphocyte count (pmedia in HIV infected children, probably due to increase in mean CD4+ lymphocyte count.

Cardiovascular disease (CVD) has emerged as a major cause of morbidity and mortality in HIV-infected adults. Research in noninfected populations has suggested that knowledge of CVD risk factors significantly influences perceptions of risk. This cross-sectional study describes CVD risk factor knowledge and risk perception in HIV-infected adults. We recruited 130 HIV-infected adults (mean age = 48 years, 62% male, 56% current smokers, mean years since HIV diagnosis, 14.7). The mean CVD risk factor knowledge score was fairly high. However, controlling for age, CVD risk factor knowledge was not predictive of perceived risk [F(1, 117) = 0.13, p > .05]. Estimated risk and perceived risk were weakly but significantly correlated; r (126) = .24, p = .01. HIV-infected adults are at increased risk for CVD. Despite having adequate risk-factor knowledge, CVD risk perception was inaccurate. Improving risk perception and developing CVD risk reduction interventions for this population are imperative.

The risks and factors contributing to major depressive episodes in HIV infection remain unclear. This 2-year prospective study compared cumulative rates and predictors of a major depressive episode in HIV-infected (HIV+) men (N=297) and uninfected (HIV-) risk-group controls (N=90). By design participants at entry were without current major depression, substance dependence or major anxiety disorder. Standardized neuromedical, neuropsychological, neuroimaging, life events, and psychiatric assessments (Structured Clinical Interview for DSM III-R) were conducted semi-annually for those with AIDS, and annually for all others. Lifetime prevalence of major depression or other psychiatric disorder did not differ at baseline between HIV+ men and controls. On a two-year follow-up those with symptomatic HIV disease were significantly more likely to experience a major depressive episode than were asymptomatic HIV+ individuals and HIV-controls (pdepression. After baseline disease stage and medical variables associated with HIV infection were controlled, a lifetime history of major depression, or of lifetime psychiatric comorbidity (two or more psychiatric disorders), predicted subsequent major depressive episode (pdepressive episode. Research cohort of men examined before era of widespread use of advanced anti-HIV therapies. Symptomatic HIV disease, but not HIV infection itself, increases intermediate-term risk of major depression. Prior psychiatric history most strongly predicted future vulnerability.

Full Text Available Introduction. Low levels of nasal NO have been associated with increased propensity to rhinosinusitis and respiratory tract infections. Our objective was to describe nasal NO levels in HIV-infected individuals versus healthy controls and determine possible risk factors for reduced nasal NO levels. Materials and Methods. HIV-infected individuals and healthy controls were recruited. Participants underwent nasal NO testing by standardized methods using a CLD88 chemiluminescence analyzer and completed the Sinonasal Outcome Test-20 (SNOT-20 on symptoms of rhinosinusitis. Results. Participants included 41 HIV-infected individuals with suppressed VL on antiretroviral therapy (ART group, 5 HIV-infected individuals with detectable VL off ART (viremic group, and 12 healthy controls (HC group. Mean nasal NO level was 253 (±77 nL/min in the ART group, 213 (±48 nL/min in the viremic group, and 289 (±68 nL/min in the HC group (p=0.133; ANOVA. There was no correlation between nasal NO level and VL in viremic individuals (r=-0.200; p=0.747. Differences were observed in mean total points on the SNOT-20 which were 19 (±16/100, 18 (±26/100, and 4 (±4/100 in the ART, viremic, and HC groups, respectively (p=0.013; ANOVA. Conclusion. Healthy individuals, HIV patients on ART, and viremic individuals off ART display similar nasal NO levels. However, rhinosinusitis symptoms remain prominent despite ART-treatment.

HIV-associated immunosuppression has been linked to an increased risk of a number of cancers, including Kaposi sarcoma (KS), non-Hodgkin's lymphoma (NHL), and invasive cervical cancer. Because prison inmates constitute one of the highest HIV/AIDS prevalent populations in the US, understanding the link between HIV infection and cancer in the correctional setting holds particular public health relevance. The study population consisted of 336,668 Texas Department of Criminal Justice inmates who were incarcerated, for any duration, between 1 January 1999 and 31 December 2001. Inmates diagnosed with HIV infection exhibited elevated rates of KS, NHL, anal cancer, and Hodgkin's disease, after adjusting for age and race. The elevated rates of cancer among HIV-infected individuals, particularly prison inmates, may be mediated, in part, by high-risk behaviours. HIV-associated risk behaviours, including unsafe sexual practices, injection drug use, and prostitution may be associated with cancer-related risk behaviours, such as smoking, excessive alcohol consumption, and poor diet. It will be important for future investigators to examine the association between HIV infection and cancer risk with sufficiently large study cohorts and appropriate longitudinal designs.

Background: Physician attitude influences the way patients cope with diagnosis and therapy in chronic severe diseases such as cancer. Previous studies showed that such an effect exists in HIV care; it is likely that it begins with the first contact with a physician. Objective: We aimed to explore in HIV-infected persons their perception of the first consultation they had with an HIV specialist (PFC-H), and whether this perception correlates with adherence to antiretroviral therapy. Method: Th...

-attributable fractions (PAF) of MI associated with smoking. RESULTS: In never smokers, HIV was not associated with an increased risk of MI (aIRR, 1.01; 95% confidence interval [CI], .41-2.54). In previous and current smokers, HIV was associated with a substantially increased risk of MI (aIRR, 1.78; 95% CI, .75......-4.24 and aIRR, 2.83; 95% CI, 1.71-4.70). The PAF associated with ever smoking (previous or current) was 72% (95% CI, 55%-82%) for HIV-infected individuals and 24% (95% CI, 3%-40%) for population controls. If all current smokers stopped smoking, 42% (95% CI, 21%-57%) and 21% (95% CI, 12%-28%) of all MIs could...

HIV-infected individuals have deficient responses to Yellow Fever vaccine (YFV) and may be at higher risk for adverse events (AE). Chronic immune activation-characterized by low CD4/CD8 ratio or high indoleamine 2,3-dioxygenase-1 (IDO) activity-may influence vaccine response in this population. We prospectively assessed AE, viremia by the YFV virus and YF-specific neutralizing antibodies (NAb) in HIV-infected (CD4>350) and -uninfected adults through 1 year after vaccination. The effect of HIV status on initial antibody response to YFV was measured during the first 3 months following vaccination, while the effect on persistence of antibody response was measured one year following vaccination. We explored CD4/CD8 ratio, IDO activity (plasma kynurenine/tryptophan [KT] ratio) and viremia by Human Pegivirus as potential predictors of NAb response to YFV among HIV-infected participants with linear mixed models. 12 HIV-infected and 45-uninfected participants were included in the final analysis. HIV was not significantly associated with AE, YFV viremia or NAb titers through the first 3 months following vaccination. However, HIV-infected participants had 0.32 times the NAb titers observed for HIV-uninfected participants at 1 year following YFV (95% CI 0.13 to 0.83, p = 0.021), independent of sex, age and prior vaccination. In HIV-infected participants, each 10% increase in CD4/CD8 ratio predicted a mean 21% higher post-baseline YFV Nab titer (p = 0.024). Similarly, each 10% increase in KT ratio predicted a mean 21% lower post-baseline YFV Nab titer (p = 0.009). Viremia by Human Pegivirus was not significantly associated with NAb titers. HIV infection appears to decrease the durability of NAb responses to YFV, an effect that may be predicted by lower CD4/CD8 ratio or higher KT ratio.

Antibody maturation and viral diversification were examined in these women.Samples collected at enrollment (N = 2,561 and 12-24 months later (N = 1,306 were available for serologic analysis using the BED and avidity assays. A subset of those samples was used for analysis of viral diversity, which was performed using a high resolution melting (HRM diversity assay. Viral diversity analysis was performed using all available samples from women in the MAA recent group (61 enrollment samples, 38 follow-up samples and the known non-recent group (43 enrollment samples, 22 follow-up samples. Diversity data from PEPI-Malawi were also compared to similar data from 169 adults in the United States (US with known recent infection (N = 102 and known non-recent infection (N = 67.In PEPI-Malawi, results from the BED and avidity assays increased over time in the MAA recent group, but did not change significantly in the MAA non-recent group. At enrollment, HIV diversity was lower in the MAA recent group than in the known non-recent group. HRM diversity assay results from women in PEPI-Malawi were similar to those from adults in the US with known duration of HIV infection.Antibody maturation and HIV diversification patterns in African women provide additional support for use of the MAA to identify populations with recent HIV infection.

Various studies have confirmed the high incidence of skeletal homeostasis modifications in subjects who are carriers of chronic HIV infections, and specific pharmacological treatments, which modify the metabolism and condition both the weight loss and the reshaping of the bones. The presence of a reduction in body mass index seems to contribute to the progressive deterioration of the skeletal framework. The aim of this study was to see whether the presence of HIV-seropositivity could constitute a risk factor for the development of osteoporosis/osteopenia, even in the light of the fact that our group was composed of patients with a concentrated age span well under the limit for both post-menopausal and senile osteoporosis, and with a median age superimposable for both sexes. Our study involved 26 HIV+ patients with an average duration of infection equal to 6.7 +/- 4.8 years, and a range of seropositive duration between 6 months to 16 years. The prominent ultrasonometrical parameters are as follows: Broadband Ultrasound Attenuation, Speed of Sound, Stiffness Index or Quantitative Ultra-sound Index, Bone Mineral Density, and T-score. The biochemical study was carried out by assessing a marker of neoformation such as seric osteocalcine, and uninary pyridinoline and deoxipyridonoline as resorption markers. The results confirmed the presence of osteoporosis/osteopenia in 46% of the samples (11%, and 35%, respectively), with a progressive reduction in bone mineral density in relation to the duration of HIV infection. Assessment of the marker for bone metabolism showed a significant increase in osteocalcine in the female population compared to the males, without any significant variations in the normal values. Extreme variability in the morphological appearance at bone level during the course of HIV infection would lead us to believe that in the genesis of various forms, depending on the mechanisms and the time involved only in the parts defined, other attributable factors

The improvement in the prognosis of HIV infection, coupled with the increase in international travel and migration, has led to a rising number of HIV infected travelers. The objective of this study was to describe the epidemiological and clinical features of returning travelers, according to their HIV status. An observational prospective study was conducted including travelers and immigrants who traveled to visit friends and relatives (VFRs) registered in the +REDIVI collaborative network (January-2009; October-2014). +REDIVI is a national network that registers information regarding infections imported by travelers and immigrants at 21 different centers using a standardized protocol. A total of 3464 travellers were identified: 72 were HIV+ (2.1%) and 3.392 HIV- (98%). HIV+ vs. HIV- travelers were often older (40.5y vs. 34.2y P=.001), VFRs (79.1% vs. 44.4%; Ptravel advice (27% vs. 37%; P=.078). The main destinations for both groups were sub-Saharan Africa and Latin America. The most frequent reasons for consultation after travel were fever, request for a health examination, gastrointestinal complaints, and abnormal laboratory tests (mainly eosinophilia and anemia), which differed between groups. The most frequent diagnoses in HIV+ travelers were malaria (38.8%), newly diagnosed HIV infection (25%), and intestinal parasites (19.4%), while for HIV- travelers the main diagnoses were "healthy" (17.9%), malaria (14%), and intestinal parasites (17.3%). The typical profile of an HIV+ traveler in +REDIVI was that of a VFR traveler who did not seek pre-travel advice and made high-risk trips. This may increase the chance of acquiring travel-related infections which may pose a special risk for HIV-infected travelers. The post-travel visit was a good opportunity for HIV infection screening.

The role the human immunodeficiency virus (HIV) and antiretroviral treatment on endothelial activation, and the subsequent relationship with cardiovascular disease, is not well understood. We investigated endothelial activation, inflammatory and cardiometabolic profiles, and measures of vascular structure and function of 66 antiretroviral treated (ART), 78 never-treated (no-ART) HIV infected and 165 HIV free Africans. Blood samples were obtained for biochemical analysis and blood pressure, pulse wave velocity (PWV) and carotid intima-media thickness (IMT) measurements were performed. The HIV infection duration was at least five years and the treatment 2.86±0.13 years. The intracellular adhesion molecule (ICAM) and vascular cell adhesion molecule (VCAM) levels were elevated in the HIV infected groups compared to the controls. The odds of higher adhesion molecule levels were increased when HIV infected (especially in the no-ART group); OR no-ART vs. no-HIV: ICAM 3.92 (2.2-7.0); VCAM 16.2 (7.5-35). ICAM and VCAM associated with HIV status and interleukin-6 (IL-6) in the total group (all pART: β=-0.28, p=0.01; ART: β=-0.22, p=0.07) and TC (no-ART: β=-0.36, pART: β=-0.27, p=0.03). The ART group had an unfavourable lipid profile compared to the no-ART group. The inflammatory markers (C-reactive protein (CRP) and IL-6), PWV and IMT did not differ between the three groups. HIV infected Africans showed endothelial activation when compared to HIV free controls. The endothelial activation was not accompanied by increased inflammation (as measured with CRP and IL-6), arterial stiffness or sub-clinical atherosclerosis. Copyright © 2015 Elsevier Ireland Ltd.

To examine factors associated with HIV infection among transgender women in Cambodia. Cross-sectional study. HIV high-burden sites including the capital city and 12 provinces. This study included 1375 sexually active transgender women with a mean age of 25.9 years (SD 7.1), recruited by using respondent-driven sampling for structured questionnaire interviews and rapid finger-prick HIV testing. HIV infection detected by using Determine antibody test. HIV prevalence among this population was 5.9%. After adjustment for other covariates, participants living in urban areas were twice as likely to be HIV infected as those living in rural areas. Participants with primary education were 1.7 times as likely to be infected compared with those with high school education. HIV infection increased with age; compared with those aged 18-24 years, the odds of being HIV infected were twice as high among transgender women aged 25-34 years and 2.8 times higher among those aged ≥35 years. Self-injection of gender affirming hormones was associated with a fourfold increase in the odds of HIV infection. A history of genital sores over the previous 12 months increased the odds of HIV infection by threefold. Transgender women with stronger feminine identity, dressing as a woman all the time, were twice as likely to be HIV infected compared with those who did not dress as a woman all the time. Having never used online services developed for transgender women in the past six months was also associated with higher odds of being HIV infected. Transgender women in Cambodia are at high risk of HIV. To achieve the goal of eliminating HIV in Cambodia, effective combination prevention strategies addressing the above risk factors among transgender women should be strengthened. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Lung cancer is the leading cause of non-AIDS-defining cancer deaths among HIV-infected individuals. Although lung cancer screening with low-dose computed tomography (LDCT) is endorsed by multiple national organizations, whether HIV-infected individuals would have similar benefit as uninfected individuals from lung cancer screening is unknown. Our objective was to determine the benefits and harms of lung cancer screening among HIV-infected individuals. We modified an existing simulation model, the Lung Cancer Policy Model, for HIV-infected patients. Veterans Aging Cohort Study, Kaiser Permanente Northern California HIV Cohort, and medical literature. Target population: HIV-infected current and former smokers. Lifetime. Population. Annual LDCT screening from ages 45, 50, or 55 until ages 72 or 77 years. Benefits assessed included lung cancer mortality reduction and life-years gained; harms assessed included numbers of LDCT examinations, false-positive results, and overdiagnosed cases. For HIV-infected patients with CD4 at least 500 and 100% antiretroviral therapy adherence, screening using the Centers for Medicare & Medicaid Services criteria (age 55-77, 30 pack-years of smoking, current smoker or quit within 15 years of screening) would reduce lung cancer mortality by 18.9%, similar to the mortality reduction of uninfected individuals. Alternative screening strategies utilizing lower screening age and/or pack-years criteria increase mortality reduction, but require more LDCT examinations. Strategies assumed 100% screening adherence. Lung cancer screening reduces mortality in HIV-infected patients with CD4 at least l500, with a number of efficient strategies for eligibility, including the current Centers for Medicare & Medicaid Services criteria.
Full Text Available Abstract Background Streptococcus pneumoniae is a major cause of human disease, especially in pre-school children and elderly people, as well as in special risk groups such as asplenic, antibody deficient patients, or presenting disruption of natural barriers. The occurrence of pneumococcal disease has increased with the onset of the HIV epidemic and the emergence of drug-resistance. Case presentation We report the case of an HIV-1-infected patient who experienced three episodes of recurrent pneumococcal meningitis over a 4-year period, despite chemoprophylaxis and capsular vaccination. Conclusions Efficacy of anti-pneumococcal chemoprophylaxis and vaccination in HIV-infected patients are discussed in the light of this particular case.

Full Text Available Persistent immune activation and microbial translocation associated with HIV infection likely place HIV-infected aging women at high risk of developing chronic age-related diseases. We investigated immune activation and microbial translocation in HIV-infected aging women in the post-menopausal ages.Twenty-seven post-menopausal women with HIV infection receiving antiretroviral treatment with documented viral suppression and 15 HIV-negative age-matched controls were enrolled. Levels of immune activation markers (T cell immune phenotype, sCD25, sCD14, sCD163, microbial translocation (LPS and biomarkers of cardiovascular disease and impaired cognitive function (sVCAM-1, sICAM-1 and CXCL10 were evaluated.T cell activation and exhaustion, monocyte/macrophage activation, and microbial translocation were significantly higher in HIV-infected women when compared to uninfected controls. Microbial translocation correlated with T cell and monocyte/macrophage activation. Biomarkers of cardiovascular disease and impaired cognition were elevated in women with HIV infection and correlated with immune activation.HIV-infected antiretroviral-treated aging women who achieved viral suppression are in a generalized status of immune activation and therefore are at an increased risk of age-associated end-organ diseases compared to uninfected age-matched controls.

The aims of this study were to 1) determine if cardiac disease can be detected in HIV-infected children by strain imaging and 2) to evaluate differences in exercise performance between HIV-infected children on antiretroviral therapy (ART) and HIV-infected children not yet on ART and in HIV-uninfected children by 6-minute walk tests (6MWTs). This cross-sectional study evaluated cardiac function by echocardiogram and exercise performance by 6MWT in HIV-infected and HIV-uninfected children 4-18 years of age in Lilongwe, Malawi. Analyses compared HIV uninfected, HIV infected not yet on ART, and HIV infected on ART. Comparisons used χ test, t test, analysis of variance and multiple linear regression. No differences were found in ejection fraction, shortening fraction or strain in 73 children not yet on ART, 149 on ART and 77 HIV-uninfected controls. As viral load increased, children had worse circumferential strain. In addition, children receiving ART had better circumferential strain than those not yet on ART. Increased CD4 percentage was associated with better longitudinal strain and farther 6MWT distance. As longitudinal strain worsened, the 6MWT distance decreased. HIV-infected children not yet on ART walked a mean of 25.8 m less than HIV-uninfected children, and HIV-infected children on ART walked 25.9 m less (P = 0.015 comparing 3 groups). HIV-uninfected children performed better on the 6MWT than HIV-infected children. Lower viral load, being on ART, and higher CD4 percentage were associated with better strain measures. Better longitudinal strain was associated with a farther 6MWT distance. Overall, ejection fraction, shortening fraction and strain measures between groups were similar, so cardiac strain did not detect cardiac dysfunction in this young population.

Objectives Building on a wealth of new empirical data, the objective of this study was to estimate the distribution of new HIV infections in Morocco by mode of exposure using the modes of transmission (MoT) mathematical model. Methods The MoT model was implemented within a collaboration with the Morocco Ministry of Health and the Joint United Nations Programme on HIV/AIDS. The model was parameterised through a comprehensive review and synthesis of HIV and risk behaviour data in Morocco, mainly through the Middle East and North Africa HIV/AIDS Synthesis Project. Uncertainty analyses were used to assess the reliability of and uncertainty around our calculated estimates. Results Female sex workers (FSWs), clients of FSWs, men who have sex with men (MSM) and injecting drug users (IDUs) contributed 14%, 24%, 14% and 7% of new HIV infections, respectively. Two-thirds (67%) of new HIV infections occurred among FSWs, clients of FSWs, MSM and IDUs, or among the stable sexual partners of these populations. Casual heterosexual sex contributed 7% of HIV infections. More than half (52%) of HIV incidence is among females, but 71% of these infections are due to an infected spouse. The vast majority of HIV infections among men (89%) are due to high-risk behaviour. A very small HIV incidence is predicted to arise from medical injections or blood transfusions (0.1%). Conclusions The HIV epidemic in Morocco is driven by HIV incidence in high-risk population groups, with commercial heterosexual sex being the largest contributor to incidence. There is a need to focus HIV response more on these populations, mainly through proactive and sustainable HIV surveillance, and the expansion and increased geographical coverage of services such as condom promotion among FSWs, voluntary counselling and testing, harm reduction and treatment.

HIV infection is associated with cancer risk. This relationship has resulted in a growing cancer burden, especially in resource-limited countries where HIV is highly prevalent. Little is known, however, about how HIV affects cancer survival in these settings. We therefore investigated the role of HIV in cancer survival in Uganda. Retrospective cohort (N = 802). Eligible cancer patients were residents of Kyadondo County, at least 18 years of age at cancer diagnosis, and diagnosed between 2003 and 2010 with one of the following: breast cancer, cervical cancer, non-Hodgkin's lymphoma, Hodgkin's lymphoma, or esophageal cancer. Patients were classified as HIV-infected at cancer diagnosis based on a documented positive HIV antibody test, medical history indicating HIV infection, or an HIV clinic referral letter. The primary outcome, vital status at 1 year following cancer diagnosis, was abstracted from the medical record or determined through linkage to the national hospice database. The risk of death during the year after cancer diagnosis was compared between cancer patients with and without evidence of HIV infection using Cox proportional hazards regression. HIV-infected cancer patients in Uganda experienced a more than two-fold increased risk of death during the year following cancer diagnosis compared to HIV-uninfected cancer patients [hazard ratio 2.28; 95% confidence interval (CI) 1.61-3.23]. This association between HIV and 1-year cancer survival was observed for both cancers with (hazard ratio 1.56; 95% CI 1.04-2.34) and without (hazard ratio 2.68; 95% CI 1.20-5.99) an infectious cause. This study demonstrates the role of HIV in cancer survival for both cancers with and without an infectious cause in a resource-limited, HIV-endemic setting.

Study Design Retrospective analysis of nationwide Veterans Health Administration (VA) clinical and administrative data. Objective Examine the association between HIV infection and the rate of spine surgery for degenerative spine disease. Summary of Background Data Combination anti-retroviral therapy (cART) has prolonged survival in patients with HIV/AIDS, increasing the prevalence of chronic conditions such as degenerative spine disease that may require spine surgery. Methods We studied all HIV infected patients under care in the VA from 1996–2008 (n=40,038) and uninfected comparator patients (n=79,039) matched on age, gender, race, year, and geographic region. The primary outcome was spine surgery for degenerative spine disease defined by ICD-9 procedure and diagnosis codes. We used a multivariate Poisson regression to model spine surgery rates by HIV infection status, adjusting for factors that might affect suitability for surgery (demographics, year, comorbidities, body mass index, cART, and laboratory values). Results Two-hundred twenty eight HIV infected and 784 uninfected patients underwent spine surgery for degenerative spine disease during 700,731 patient-years of follow-up (1.44 surgeries per 1,000 patient-years). The most common procedures were spinal decompression (50%), and decompression and fusion (33%); the most common surgical sites were the lumbosacral (50%), and cervical (40%) spine. Adjusted rates of surgery were lower for HIV infected patients (0.86 per 1,000 patient-years of follow-up) than for uninfected patients (1.41 per 1,000 patient-years; IRR 0.61, 95% CI: 0.51, 0.74, Pdegenerative spine disease. Possible explanations include disease prevalence, emphasis on treatment of non-spine HIV-related symptoms, surgical referral patterns, impact of HIV on surgery risk-benefit ratio, patient preferences, and surgeon bias.

Introduction: HIV infections and the use of amphetamine-type stimulants (ATS) among men who have sex with men (MSM) have been increasing internationally, but the role of ATS use as a co-factor for HIV infection remains unclear. We aimed to summarize the association between ATS use and HIV infection among MSM. Methods: We conducted a systematic search of MEDLINE, EMBASE, GLOBAL HEALTH and PsycINFO for relevant English, peer-reviewed articles of quantitative studies published between 1980 and 2...

BACKGROUND: Modern combination antiretroviral therapy (cART) has improved survival for people living with HIV (PLWHIV). Non-AIDS comorbidities have replaced opportunistic infections as leading causes of mortality and morbidity, and are becoming a key health concern as this population continues....../DESIGN: The Copenhagen comorbidity in HIV-infection (COCOMO) study is an observational, longitudinal cohort study. The study was initiated in 2015 and recruitment is ongoing with the aim of including 1500 PLWHIV from the Copenhagen area. Follow-up examinations after 2 and 10 years are planned. Uninfected controls...... (PBMC), urine, and stool samples are collected in a biobank for future studies. Data will be updated through periodical linking to national databases. DISCUSSION: As life expectancy for PLWHIV improves, it is essential to study long-term impact of HIV and cART. We anticipate that findings from...

Two hundred consecutive patients with herpes zoster attending the skin clinic at the Kilimanjaro Christian Medical Centre (KCMC) were examined and checked for HIV infection. They ranged in age from 10 months to 86 years with the majority in their 20s and 30s. The dermatomes involved were thoracic (97), trigeminal (50), cervical (37), lumbar (19) and sacral (3). Six (3%) had more than one dermatome involved and 2 (1%) had disseminated disease. Only 2 (1%) had severe ulceration of the skin and all healed in less than 4 weeks. In children under the age of 10 years and in adults between the ages of 20 and 49 years virtually 100% were HIV positive; even in the age group 50-59 more than three-quarters were HIV positive. We conclude that the presence of herpes zoster at any site is a good indication that the patient is HIV positive except in the teens and the very elderly.

Full Text Available ABSTRACT Introduction; Hematological abnormalities are a common complication of HIV infection. Bone marrow abnormalities occur in all stages of HIV infection. Present work was carried out to study the bone marrow abnormalities in patients with HIV/AIDS. Methods: 160 patients of HIV +ve were included in the study. A complete blood count, relevant biochemical investigations, CD4 counts were done, besides a thorough history and clinical examination. HIV positive patients were classified as those having AIDS and those without AIDS according to NACO criteria. Bone marrow examination was performed for indication of anemia, leucopenia, pancytopenia and thrombocytopenia. Results: As per CDC criteria 59.81% patients had AIDS in 107 patients. The most common hematological abnormality was anemia, seen in 93.12% patients. Bone marrow was normocellular in 79.06% of non-AIDS and 79.68% of AIDS, hypocellular in 13.95%.Thrombocytopenia was seen in 4 cases of ART (4.93% and 3 cases (4.68% of AIDS group. Abnormal cells like plasma cell, histocyte and toxic granule found in bone marrow. Conclusions: Myelodysplasia was more common in AIDS than in non AIDS patients. Granulocytic series is most commonly associated with evidence of dysplasia. Anemia in HIV patients can be a good clinical indicator to predict and access the underlying immune status. Thus bone marrow study is imperative to methodically observe and follow clinical and laboratory aberration in such patients in order to improve our diagnostic and therapeutic skills pertinent to HIV/AIDS.

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

Theory predicts that land ownership empowers women to avoid HIV acquisition by reducing their reliance on risky survival sex and enhancing their ability to negotiate safer sex. However, this prediction has not been tested empirically. Using a sample of 5511 women working in the agricultural sector from the 1998, 2003 and 2008-09 Kenya Demographic and Health Surveys, we examined the relationship between women's land ownership and participation in transactional sex, multiple sexual partnerships and unprotected sex, and HIV infection status. We controlled for demographic characteristics and household wealth, using negative binomial and logistic regression models. Women's land ownership was associated with fewer sexual partners in the past year (incidence rate ratio, 0.98; 95% confidence interval [CI], 0.95-1.00) and lower likelihood of engaging in transactional sex (odds ratio [OR], 0.67; 95% CI: 0.46-0.99), indicators of reduced survival sex, but was not associated with unprotected sex with casual partners (OR, 0.64; 95% CI, 0.35-1.18) or with unprotected sex with any partner among women with high self-perceived HIV risk (OR, 1.02; 95% CI, 0.57-1.84), indicating no difference in safer sex negotiation. Land ownership was also associated with reduced HIV infection among women most likely to engage in survival sex, i.e., women not under the household headship of a husband (OR, 0.40; 95% CI, 0.18-0.89), but not among women living in husband-headed households, for whom increased negotiation for safer sex would be more relevant (OR, 1.74; 95% CI, 0.92-3.29). These findings suggest that reinforcing women's land rights may reduce reliance on survival sex and serve as a viable structural approach to HIV prevention, particularly for women not in a husband's household, including unmarried women and female household heads.

Full Text Available Background: The study goal was to describe etravirine pharmacokinetics during pregnancy and postpartum in HIV-infected women. Methods: IMPAACT P1026s and PANNA are on-going, nonrandomized, open-label, parallel-group, multi-center phase-IV prospective studies in HIV-infected pregnant women. Intensive steady-state 12 or 24 hour pharmacokinetic profiles were performed from 2nd trimester through postpartum. Etravirine was measured at two labs using validated ultra performance liquid chromatography (detection limits: 0.020 mcg/mL and 0.026 mcg/mL. Results: Fifteen women took etravirine 200 mg twice-daily dosing and one took 400 mg once-daily. Etravirine AUC0-12 was significantly higher in the 3rd trimester compared to paired postpartum data by 45% (median 8.3 mcg*hr/mL versus 5.7 mcg*hr/mL, p = 0.086. Etravirine apparent oral clearance was significantly lower in the 3rd trimester of pregnancy compared to paired postpartum data (median 24 L/h versus 35 L/h, p = 0.038. The median ratio of cord blood to maternal plasma concentration at delivery was 0.56 (range: 0.19 - 4.25 and no perinatal transmission occurred. Conclusion: Etravirine apparent oral clearance is reduced and exposure increased during the third trimester of pregnancy. Based on prior dose-ranging and safety data, no dose adjustment is necessary for maternal health but the effects of etravirine in utero are unknown. Maternal health and infant outcomes should be closely monitored until further infant safety data are available. The IMPAACT protocol P1026s and PANNA study are registered at ClinicalTrials.gov under NCT00042289 and NCT00825929.

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.

Full Text Available Abstract Background Low concentrations of serum zinc have been reported in HIV infected adults and are associated with disease progression and an increased risk of death. Few studies have been conducted in HIV infected children in Africa. We determined serum zinc levels and factors associated with zinc deficiency in HIV infected Ugandan children. Methods We measured the baseline zinc status of 247 children aged 1-5 years enrolled in a randomised trial for multiple micronutrient supplementation at paediatric HIV clinics in Uganda (http://ClinicalTrials.gov NCT00122941. Zinc status was determined using inductively coupled atomic emission spectrophotometry (ICP-AES. Clinical and laboratory characteristics were compared among zinc deficient (zinc Results Of the 247 children, 134 (54.3% had low serum zinc ( Conclusion Almost two thirds of HAART naïve and a third of HAART treated HIV infected children were zinc deficient. Increased access to HAART among HIV infected children living in Uganda might reduce the prevalence of zinc deficiency.
Full Text Available Abstract Background HIV infection increases the risk of placental malaria, which is associated with poor maternal and infant outcomes. Recommendations in Uganda are for HIV-infected pregnant women to receive daily trimethoprim-sulphamethoxazole (TS and HIV-uninfected women to receive intermittent sulphadoxine-pyrimethamine (SP. TS decreases the risk of malaria in HIV-infected adults and children but has not been evaluated among pregnant women. Methods This was a cross sectional study comparing the prevalence of placental malaria between HIV-infected women prescribed TS and HIV-uninfected women prescribed intermittent preventive therapy with sulphadoxine-pyrimethamine (IPT-SP in a high malaria transmission area in Uganda. Placental blood was evaluated for malaria using smear and PCR. Results Placentas were obtained from 150 HIV-infected women on TS and 336 HIV-uninfected women on IPT-SP. The proportion of HIV-infected and HIV-uninfected women with placental malaria was 19% vs. 26% for those positive by PCR and 6% vs. 9% for those positive by smear, respectively. Among all infants, smear+ placental malaria was most predictive of low birth weight (LBW. Primigravidae were at higher risk than multigravidae of having placental malaria among HIV-uninfected, but not HIV-infected, women. Adjusting for gravidity, age, and season at the time of delivery, HIV-infected women on TS were not at increased risk for placental malaria compared to HIV-uninfected women on IPT-SP, regardless of the definition used. Conclusion Prevalence of placental malaria was similar in HIV-infected women on TS and HIV-uninfected women on IPT-SP. Nonetheless, while nearly all of the women in this study were prescribed anti-folates, the overall risk of placental malaria and LBW was unacceptably high. The population attributable risk of placental malaria on LBW was substantial, suggesting that future interventions that further diminish the risk of placental malaria may have a

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

Studies in persons without HIV infection have compared adipose tissue measured by dual-energy X-ray absorptiometry (DXA) and magnetic resonance imaging (MRI), but no such study has been conducted in HIV-infected (HIV+) subjects, who have a high prevalence of regional fat loss. We compared DXA- with MRI-measured trunk, leg, arm, and total fat in HIV+ and control subjects. A cross-sectional analysis was conducted in 877 HIV+ subjects and 260 control subjects in FRAM (Study of Fat Redistribution and Metabolic Change in HIV Infection), stratified by sex and HIV status. Univariate associations of DXA with MRI were strongest for total and trunk fat (r > or = 0.92) and slightly weaker for leg (r > or = 0.87) and arm (r > or = 0.71) fat. The average estimated limb fat was substantially greater for DXA than for MRI for HIV+ and control men and women (all P < 0.0001). Less of a difference was observed in trunk fat measured by DXA and MRI, but the difference was still statistically significant (P < 0.0001). Bland-Altman plots showed increasing differences and variability. Greater average limb fat in control and HIV+ subjects (both P < 0.0001) was associated with greater differences between DXA and MRI measurements. Because the control subjects had more limb fat than did the HIV+ subjects, greater amounts of fat were measured by DXA than by MRI when control subjects were compared with HIV+ subjects. More HIV+ subjects had leg fat in the bottom decile of the control subjects by DXA than by MRI (P < 0.0001). Although DXA- and MRI-measured adipose tissue depots correlate strongly in HIV+ and control subjects, differences increase as average fat increases, particularly for limb fat. DXA may estimate a higher prevalence of peripheral lipoatrophy than does MRI in HIV+ subjects.

Prevalence of HIV among pregnant women in India is of great concern, especially to prevent HIV in children. Mother-to-child transmission of HIV is the most common cause of transmission of HIV in children. Prevalence of HIV infection in pregnant women in India has ranged from 0.7% to 1.2%. Thus, estimating prevalence of HIV in pregnant women would aid in developing and prioritizing prevention of parent-to-child transmission of HIV programs. All pregnant women referred to the antenatal clinic from 1993 onward were tested for HIV infection by ELISA test after pretest counseling. A woman was diagnosed to be HIV infected if she tested positive on more than two HIV ELISA tests. Prevalence of HIV infection in them was calculated and also whether there was an increasing trend was determined. A total of 123,439 pregnant women were tested for HIV from 1993 to 2004, of which 1797 women were HIV infected. Overall, the prevalence rate was found to be 1.4%. Prevalence rose from 0.76% in 1993 to 2.37% in 1998. However, from 2004, the prevalence has decreased to 0.6%. Prevalence of HIV in pregnant women in Mumbai is decreasing.

Full Text Available For certain subgroups within people living with the human immunodeficiency virus (HIV [active tuberculosis (TB, pregnant women, children <5 years old, and serodiscordant couples], the World Health Organization recommends antiretroviral therapy (ART irrespective of CD4 count. Another subgroup which has received increased attention is “HIV-infected presumptive TB patients without TB”. In this study, we assess the proportion of HIV-infected presumptive TB patients eligible for ART in Karnataka State (population 60 million, India. This was a cross-sectional analysis of data of HIV-infected presumptive TB patients diagnosed in May 2015 abstracted from national TB and HIV program records. Of 42,585 presumptive TB patients, 28,964 (68% were tested for HIV and 2262 (8% were HIV positive. Of the latter, 377 (17% had active TB. Of 1885 “presumptive TB patients without active TB”, 1100 (58% were already receiving ART. Of the remaining 785 who were not receiving ART, 617 (79% were assessed for ART eligibility and of those, 548 (89% were eligible for ART. About 90% of “HIV-infected presumptive TB patients without TB” were eligible for ART. This evidence supports a public health approach of starting all “HIV-infected presumptive TB patients without TB” on ART irrespective of CD4 count in line with global thinking about ‘test and treat’.

African American women have disproportionately high prevalence rates of HIV and cervical cancer. HIV-infected women are significantly less likely to obtain recommended cervical cancer screenings than HIV-uninfected women. The purpose of this study was to examine sociocultural and structural factors associated with cervical cancer screening among HIV-infected African American in Alabama. The PEN-3 Model and the Health Belief Model were used as theoretical frameworks. In-depth interviews were conducted with twenty HIV-infected African American women to identify perceptions, enablers, and nurturers, perceived susceptibility, perceived severity, and perceived benefits related to cervical cancer and screening. The most common positive perceptions, enablers, and nurturers that contributed to cervical cancer screening included internal motivation and awareness of the importance of HIV-infected women getting Pap tests due to their weakened immune system. Negative perceptions, enablers, and nurturers included lack of knowledge about cervical cancer and screening, and lack of perceived susceptibility to cervical cancer. The results of this study can be used to guide the development of culturally relevant cervical cancer and screening education interventions aimed at increasing cervical cancer screening adherence among HIV-infected African American women.

Full Text Available Cases of Human Immunodeficiency Virus (HIV infection in Pati District increase, particularly among housewives. The aim of this study was to analyse the risk factors of HIV infection among housewives in Pati District using case-control study design. The respondents were 90 housewives divided into case and control group. The case group consisted of 30 housewives living with HIV, while the control group comprised 60 housewives living in the similar area of the counterparts. The data collection was focused on demographic, sexual behaviour, and sociocultural variables possessed by housewives and their husbands. The study resulted that the risk factors of HIV infection among housewives based on bivariate analysis were housewife’s level of education, husband’s level of education, husband’s occupation, housewife’s sexual transmission disease (STD record, husband’s STD record, husband’s participation in religious activities, and husband’s alcohol drinking habit. The risk factors that fitted to logistic regression model were education level and alcoholic behaviour of husbands that contributed to 29.1% HIV infection among housewives. In conclusion, the husband’s variables are proved having stronger and very significant correlation with HIV infection among housewives than housewife’s variables.

Due to improved access and adherence to antiretroviral therapy (ART), most HIV-infected persons worldwide are predicted to live longer. Nowadays the cause of death for most HIV-infected persons has changed to serious non-AIDS events (SNAEs) which is due to low-grade viremia. HIV patients with ART who had undergone CD4 cell count above 500/uL and there is an increase in hs-CRP despite an undetectable viral load. Some conditions CD8 cells count do not decrease with CD4 cells repairs. We researched in Prof Kandou General Hospital with a total sample of 35 HIV patients who had received ART with the level of CD4>350/uL. CD8 levels, CD4/CD8 ratio, and hs-CRP were assessed. This research is analytic descriptive with cross-sectional study design and analysis uses Spearman correlation. The mean CD8 during the study was 1291.8 (IQR 319-2610cells/uL), the mean ratio of CD4:CD8 was 0.57 (IQR 0.16-1.24) and median hs-CRP is 2.18 (IQR 0.3-6.6mg/dL). There was a significant positive correlation between CD8 and increased hs-CRP (r=0.369, pCD4/CD8 ratio and hs-CRP (r=-0.370, p<0.05).

Full Text Available Abstract Background Tuberculosis (TB is a major health problem and HIV is the major cause of the increase in TB. Sub-Saharan Africa is endemic for both TB and HIV infection. Determination of the prevalence of M. tuberculosis strains and their drug susceptibility is important for TB control. TB positive culture, BAL fluid or sputum samples from 130 patients were collected and genotyped. The spoligotypes were correlated with anti-tuberculous drug susceptibility in HIV-infected and non-HIV patients from Tanzania. Results One-third of patients were TB/HIV co-infected. Forty-seven spoligotypes were identified. Fourteen isolates (10.8% had new and unique spoligotypes while 116 isolates (89.2% belonged to 33 known spoligotypes. The major spoligotypes contained nine clusters: CAS1-Kili 30.0%, LAM11- ZWE 14.6%, ND 9.2%, EAI 6.2%, Beijing 5.4%, T-undefined 4.6%, CAS1-Delhi 3.8%, T1 3.8% and LAM9 3.8%. Twelve (10.8% of the 111 phenotypically tested strains were resistant to anti-TB drugs. Eight (7.2% were monoresistant strains: 7 to isoniazid (INH and one to streptomycin. Four strains (3.5% were resistant to multiple drugs: one (0.9% was resistant to INH and streptomycin and the other three (2.7% were MDR strains: one was resistant to INH, rifampicin and ethambutol and two were resistant to all four anti-TB drugs. Mutation in the katG gene codon 315 and the rpoB hotspot region showed a low and high sensitivity, respectively, as predictor of phenotypic drug resistance. Conclusion CAS1-Kili and LAM11-ZWE were the most common families. Strains of the Beijing family and CAS1-Kili were not or least often associated with resistance, respectively. HIV status was not associated with spoligotypes, resistance or previous TB treatment.

Non-alcoholic fatty liver disease is one of the most frequent chronic hepatic conditions worldwide. The spectrum of non-alcoholic fatty liver disease goes from hepatic steatosis to steatohepatitis, cirrhosis, and hepatocellular carcinoma. Risk factors for non-alcoholic fatty liver disease are metabolic, mainly obesity and the accompanying consequences. Treatment and prevention of non-alcoholic fatty liver disease should target those metabolic abnormalities. The frequency of and the factors associated with hepatic steatosis in HIV infection seem to be similar to those reported in the general population, though direct comparisons are lacking. Hepatic steatosis in HIV infection may also be secondary to antiretroviral drugs or HCV-related factors in HCV-coinfected subjects. However, more recent data suggest that hepatic steatosis in HIV infection represents true non-alcoholic fatty liver disease. As such, management of non-alcoholic fatty liver disease in HIV infection should follow the same principles as in the general population.

Studies in persons without HIV infection have compared percentage body fat (%BF) and waist circumference as markers of risk for the complications of excess adiposity, but only limited study has been conducted in HIV-infected subjects. We compared anthropometric and magnetic resonance imaging (MRI)-based adiposity measures as correlates of metabolic complications of adiposity in HIV-infected and control subjects. The study was a cross-sectional analysis of 666 HIV-positive and 242 control subjects in the Fat Redistribution and Metabolic Change in HIV Infection (FRAM) study assessing body mass index (BMI), waist (WC) and hip (HC) circumferences, waist-to-hip ratio (WHR), %BF, and MRI-measured regional adipose tissue. Study outcomes were 3 metabolic risk variables [homeostatic model assessment (HOMA), triglycerides, and HDL cholesterol]. Analyses were stratified by sex and HIV status and adjusted for demographic, lifestyle, and HIV-related factors. In HIV-infected and control subjects, univariate associations with HOMA, triglycerides, and HDL were strongest for WC, MRI-measured visceral adipose tissue, and WHR; in all cases, differences in correlation between the strongest measures for each outcome were small (r HDL, WC appeared to be the best anthropometric correlate of metabolic complications, whereas, for triglycerides, the best was WHR. Relations of simple anthropometric measures with HOMA, triglycerides, and HDL cholesterol are approximately as strong as MRI-measured whole-body adipose tissue depots in both HIV-infected and control subjects.

Yellow fever (YF) is an acute viral haemorrhagic disease prevalent in tropical Africa and Latin America. The World Health Organization (WHO) estimates that there are 200,000 cases of YF and 30,000 deaths worldwide annually. Treatment for YF is supportive, but a live attenuated virus vaccine is effective for preventing infection. WHO recommends immunisation for all individuals > 9 months living in countries or areas at risk. However, the United States Advisory Committee on Immunization Practices (ACIP) advises that YF vaccine is contraindicated in individuals with HIV. Given the large populations of HIV-infected individuals living in tropical areas where YF is endemic, YF vaccine may be an important intervention for preventing YF in immunocompromised populations. To assess the risk and benefits of YF immunisation for people infected with HIV. We used standard Cochrane methods to search electronic databases and conference proceedings with relevant search terms without limits to language. Randomised controlled trials and cohort studies of individuals with HIV infection who received YF vaccine (17DD or 17D-204). Two authors screened abstracts of references identified by electronic or bibliographic searches according to inclusion and exclusion criteria as detailed in the protocol. We identified 199 references and examined 19 in detail for study eligibility. Data were abstracted independently using a standardised abstraction form. Three cohort studies were included in the review. They examined 484 patients with HIV infection who received YF immunisation. Patients with HIV infection developed significantly lower concentrations of neutralising antibodies in the first year post immunisation compared to uninfected patients, though decay patterns were similar for recipients regardless of HIV infection. No study patient with HIV infection suffered serious adverse events as a result of YF vaccination. YF vaccination can produce protective levels of neutralising antibodies in

of the absolute and abundance (relative content in these cell populations in comparison with healthy donors for tuberculosis and HIV infection was noticed. Absolute content of Tcyt Eff, compared with healthy donors (76.1 [20.7; 143.5], 4-fold increases in the group of HIV+TB+ and 2 times in groups TB+HIV– and TB–HIV+. Th EM content increases only at TB+HIV– group compare to healthy donors. In groups of patients with HIV infection (TB–HIV+ and TB+HIV+ a decrease in the content of these cells was observed. Thus, our work shows that the population of Th EM and Tcyt Eff could potentially be viewed as universal biomarkers for two socially significant infectious diseases: tuberculosis and HIV infection. In future experiments, it is necessary to validate these results to ensure specificity and determine the number of Th EM and Tcyt Eff specificly induced by Mtb antigens.

Vertically transmitted HIV infection is a major problem in the developing world due to the poor availability of antiretroviral agents to pregnant women. HIV is a neurotrophic virus and causes devastating neurological insults to the immature brain. The effects of the virus are further compounded by the opportunistic infections and neoplasms that occur as a result of the associated immune suppression. This review focuses on the imaging features of HIV infection and its complications in the central nervous system. (orig.)

Despite advances in the treatment of HIV, HIV-infected people remain at increased risk for many cancers, and the number of non-AIDS-defining cancers is increasing with the aging of the HIV-infected population. No prior study has comprehensively evaluated the effect of HIV on cancer-specific mortality. We identified cases of 14 common cancers occurring from 1996 to 2010 in six US states participating in a linkage of cancer and HIV/AIDS registries. We used Cox regression to examine the association between patient HIV status and death resulting from the presenting cancer (ascertained from death certificates), adjusting for age, sex, race/ethnicity, year of cancer diagnosis, and cancer stage. We included 1,816,461 patients with cancer, 6,459 (0.36%) of whom were HIV infected. Cancer-specific mortality was significantly elevated in HIV-infected compared with HIV-uninfected patients for many cancers: colorectum (adjusted hazard ratio [HR], 1.49; 95% CI, 1.21 to 1.84), pancreas (HR, 1.71; 95% CI, 1.35 to 2.18), larynx (HR, 1.62; 95% CI, 1.06 to 2.47), lung (HR, 1.28; 95% CI, 1.17 to 1.39), melanoma (HR, 1.72; 95% CI, 1.09 to 2.70), breast (HR, 2.61; 95% CI, 2.06 to 3.31), and prostate (HR, 1.57; 95% CI, 1.02 to 2.41). HIV was not associated with increased cancer-specific mortality for anal cancer, Hodgkin lymphoma, or diffuse large B-cell lymphoma. After further adjustment for cancer treatment, HIV remained associated with elevated cancer-specific mortality for common non-AIDS-defining cancers: colorectum (HR, 1.40; 95% CI, 1.09 to 1.80), lung (HR, 1.28; 95% CI, 1.14 to 1.44), melanoma (HR, 1.93; 95% CI, 1.14 to 3.27), and breast (HR, 2.64; 95% CI, 1.86 to 3.73). HIV-infected patients with cancer experienced higher cancer-specific mortality than HIV-uninfected patients, independent of cancer stage or receipt of cancer treatment. The elevation in cancer-specific mortality among HIV-infected patients may be attributable to unmeasured stage or treatment differences as well

Abstract This observational study aimed to describe immunopathogenesis and treatment outcomes in children with and without severe acute malnutrition (SAM) and HIV-infection. We studied markers of microbial translocation (16sDNA), intestinal damage (iFABP), monocyte activation (sCD14), T-cell activation (CD38, HLA-DR) and immune exhaustion (PD1) in 32 HIV-infected children with and 41 HIV-infected children without SAM prior to initiation of antiretroviral therapy (ART) and cross-sectionally compared these children to 15 HIV-uninfected children with and 19 HIV-uninfected children without SAM. We then prospectively measured these markers and correlated them to treatment outcomes in the HIV-infected children at 48 weeks following initiation of ART. Plasma levels of 16sDNA, iFABP and sCD14 were measured by quantitative real time PCR, ELISA and Luminex, respectively. T cell phenotype markers were measured by flow cytometry. Multiple regression analysis was performed using generalized linear models (GLMs) and the least absolute shrinkage and selection operator (LASSO) approach for variable selection. Microbial translocation, T cell activation and exhaustion were increased in HIV-uninfected children with SAM compared to HIV-uninfected children without SAM. In HIV-infected children microbial translocation, immune activation, and exhaustion was strongly increased but did not differ by SAM-status. SAM was associated with increased mortality rates early after ART initiation. Malnutrition, age, microbial translocation, monocyte, and CD8 T cell activation were independently associated with decreased rates of CD4% immune recovery after 48 weeks of ART. SAM is associated with increased microbial translocation, immune activation, and immune exhaustion in HIV-uninfected children and with worse prognosis and impaired immune recovery in HIV-infected children on ART.

It has been demonstrated that patients on highly active antiretroviral therapy are at increased risk for developing metabolic abnormalities that include elevated levels of serum triglycerides and low-density lipoprotein cholesterol and reduced levels of high-density lipoprotein cholesterol. This dyslipidemia is similar to that seen in the metabolic syndrome, raising the concern that highly active antiretroviral therapy also potentially increases the risk for cardiovascular complications. This paper reviews the contribution of both HIV infection and the different components of highly active antiretroviral therapy to dyslipidemia and the role of these abnormalities toward increasing the risk of cardiovascular disease in HIV-infected patients; therapeutic strategies to manage these risks are also considered.

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

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.

Rapid diagnostic tests (RDTs) are the primary diagnostic tools for HIV used in resource-constrained settings. Without a proper confirmation algorithm, there is concern that false-positive (FP) RDTs could result in misdiagnosis of HIV infection and inappropriate antiretroviral treatment (ART) initiation, but programmatic data on FP are few. We examined the accuracy of RDT diagnosis among HIV-infected pregnant women attending public sector antenatal services in Cape Town, South Africa. We describe the proportion of women found to have started on ART erroneously due to FP RDT results based on pre-ART viral load (VL) testing and enzyme-linked immunosorbent assay (ELISA). We analysed 952 consecutively enrolled pregnant women diagnosed as HIV infected based on two RDTs per local guideline and found 4.5% (43/952) of pre-ART VL results to be HIV RDT diagnoses were found to be FP. We estimate that using ELISA to confirm all positive RDTs would cost $1110 (uncertainty interval $381-$5382) to identify one patient erroneously initiated on ART, while it costs $3912 for a lifetime of antiretrovirals with VL monitoring for one person. Compared to the cost of confirming the RDT-based diagnoses, the cost of HIV misdiagnosis is high. While testing programmes based on RDT should strive for constant quality improvement, where resources permit, laboratory confirmation algorithms can play an important role in strengthening the quality of HIV diagnosis in the era of universal ART.

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 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.

As a first step in designing an AIDS prevention program at a large factory in Kinshasa, Zaire, we collected information on attitudes towards human immunodeficiency virus (HIV) infection and acquired immunodeficiency syndrome (AIDS) from factory foremen and their wives. Trained moderators conducted twelve focus group discussions (from November through December 1987) that addressed knowledge, attitudes and beliefs about HIV infection and AIDS. In general, participants were familiar with HIV infection and AIDS and considered these conditions leading health problems in Kinshasa. Although participants had a fairly accurate understanding of the causes of HIV infection, modes of transmission and preventive measures, many myths and misconceptions existed. Many participants did not believe that condom use would consistently prevent infection through sexual intercourse. Participants strongly favored the counseling of seropositive persons but showed less consensus about whether the spouse of a seropositive person should be notified of the partner's test result. Participants predicted that couples in which one member is seropositive and the other is not would experience marital discord and friction with family, neighbors and co-workers. These findings were applied to the development of a counseling and educational program for seropositive factory employees and their spouses.

To estimate the coverage of the reporting of cases of HIV-infected pregnant women, to estimate the increase in the coverage of the reporting with the routine search of data in other Brazilian health information systems, and to identify missed opportunities for identification of HIV-infected pregnant women in Brazilian maternity hospitals. This is a descriptive study on the linkage of Brazilian databases with primary data from the "Nascer no Brasil" study and secondary database collection from national health information systems. The "Nascer no Brasil" is a national-based study carried out in 2011-2012 with 23,894 pregnant women, which identified HIV-infected pregnant women using prenatal and medical records. We searched for cases of HIV-infected pregnant women identified in the "Nascer no Brasil" study in the Information System of Notifiable Diseases, the Control System for Laboratory Tests of the National CD4+/CD8+ Lymphocyte Count and HIV Viral Load Network, and the Logistics Control System for Medications. We used the OpenRecLink software for the linkage of databases. We estimated the notification coverage, with the respective confidence interval, of the evaluated Brazilian health information systems. We estimated the coverage of the reporting of HIV-infected pregnant women in the Information System of Notifiable Diseases as 57.1% (95%CI 42.9-70.2), and we located 89.3% of the HIV-infected pregnant women (95%CI 81.2-94.2) in some of the Brazilian health information systems researched. The search in other national health information systems would result in an increase of 57.1% of the reported cases. We identified no missed opportunities for the diagnosis of HIV+ in pregnant women in the maternity hospitals evaluated by the "Nascer no Brasil" study. The routine search for information in other Brazilian health information systems, a procedure carried out by the Ministry of Health for cases of AIDS in adults and children, should be adopted for cases of HIV in

The burden of Kaposi sarcoma (KS) in human immunodeficiency virus (HIV)-infected children and adolescents on combination antiretroviral therapy (cART) has not been compared globally. We analyzed cohort data from the International Epidemiologic Databases to Evaluate AIDS and the Collaboration of Observational HIV Epidemiological Research in Europe. We included HIV-infected children aged origin, sex, cART start year, age, and HIV/AIDS stage at cART initiation. We included 24 991 children from eastern Africa, southern Africa, Europe and Asia; 26 developed KS after starting cART. Incidence rates per 100 000 person-years (PYs) were 86 in eastern Africa (95% confidence interval [CI], 55-133), 11 in southern Africa (95% CI, 4-35), and 81 (95% CI, 26-252) in children of sub-Saharan African (SSA) origin in Europe. The KS incidence rates were 0/100 000 PYs in children of non-SSA origin in Europe (95% CI, 0-50) and in Asia (95% CI, 0-27). KS risk was lower in girls than in boys (adjusted HR [aHR], 0.3; 95% CI, .1-.9) and increased with age (10-15 vs 0-4 years; aHR, 3.4; 95% CI, 1.2-10.1) and advanced HIV/AIDS stage (CDC stage C vs A/B; aHR, 2.4; 95% CI, .8-7.3) at cART initiation. HIV-infected children from SSA but not those from other regions, have a high risk of developing KS after cART initiation. Early cART initiation in these children might reduce KS risk. © The Author 2016. Published by Oxford University Press for the Infectious Diseases Society of America. All rights reserved.

METHODS: We prospectively included HIV......BACKGROUND: Patients infected with human immunodeficiency virus (HIV) appear to be at increased risk of cardiovascular disease (CVD). The ankle-brachial index (ABI) is a well-established screening tool for peripheral arterial disease (PAD) and future cardiovascular events in the general population....... In contrast, a strong correlation was found between cIMT and traditional risk factors. Values of post-exercise ABI and cIMT were not correlated. The current ART did not influence ABI values. CONCLUSIONS: We found a low prevalence of PAD in HIV-infected patients. ABI did not correlate with CVD risk factors...

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.

was compared to a multidimensional clustering tool, FLOw Clustering with K (FLOCK) in two cohorts of 47 untreated HIV-infected individuals and 21 age and sex matched healthy controls. In order to reduce the subjectivity of FLOCK, we developed an "artificial reference", using 2% of all CD4+ gated T cells from...... each of the HIV-infected individuals. Principle component analyses demonstrated that using an artificial reference lead to a better separation of the HIV-infected individuals from the healthy controls as compared to using a single HIV-infected subject as a reference or analyzing data manually. Multiple...... correlation analyses between laboratory parameters and pathological CD4+ clusters revealed that the CD4/CD8 ratio was the preeminent surrogate marker of CD4+ T cells dysfunction using all three methods. Increased frequencies of an early-differentiated CD4+ T cell cluster with high CD38, HLA-DR and PD-1...

HIV infection and anaemia are major public-health problems in Africa and are important factors associated with an increased risk of adverse pregnancy outcomes. The objective of this study was to determine the prevalence of HIV infection and anaemia among pregnant women attending antenatal clinics in southeastern Nigeria. To achieve this, a cross-sectional survey was conducted during July 2005-June 2006 using standard techniques. Of 815 pregnant women studied, 31 (3.8%, 95% confidence interval [CI] 2.5-5.1) were HIV-positive. Maternal age and gestational age were not associated with HIV infection (p > 0.05). The prevalence of anaemia (Hb anaemia (Hb prevalence of anaemia was observed among individuals in their second pregnancy trimester (p anaemia are preventable, antenatal care services could serve as a pivotal entry point for simultaneous delivery of interventions for the prevention and control of HIV infection and anaemia in pregnant women.

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

In HIV-infected patients, reduced ability to work may be an important component of the societal costs of this disease. Few data about productivity costs in HIV-infected patients are available. The goals of this study were to estimate productivity costs in the HIV-infected population in Switzerland and to identify characteristics that may influence patient productivity. This cross-sectional study included all patients younger than retirement age (65 years for men and 62 years for women) who were enrolled in the Swiss HIV Cohort Study in 2002. Measures of productivity losses in this population were based on patients' ability to work and the median monthly wage rates adjusted for age, sex, and educational level in Switzerland. Factors associated with ability to work were analyzed in a multivariate ordinary logistic regression (proportional odds) model. As of July 1, 2002, the exchange rate for US dollars to Swiss francs (CHF) was US $1.00 approximately equal to CHF 1.48. A total of 5319 HIV-infected patients (3665 men [68.9%] and 1655 women [31.1%]; mean [SD] age, 40.6 [8.4] years; range, 17-64 years) were included in the study. The mean annual productivity loss per patient was estimated at CHF 22,910 (95% CI, CHF 22,064-CHF 23, 756). Ability to work was independently associated with the following (P increase: odds ratio [OR], 0.60 [95% CI, 0.54-0.62]), sex (female/male: OR, 0.73 [95% CI, 0.63-0.84]), history of IV drug use (OR, 0.22 [95% CI, 0.19-0.26]), time since first positive HIV test (>10 years vs or =501 vs 0-200 cells/microL: OR, 2.01 [95%, CI, 1.64-2.46]), history of AIDS-indicator disease (OR, 0.47 [95% CI, 0.41-0.55]), stable partnership during the last 6 months (OR, 1.63 [95% CI, 1.43-1.86]), and educational level (higher vs basic: OR, 1.68 [95% CI, 1.45-1.95]). Productivity losses to society for the HIV-infected population appeared to be substantial in this analysis. Given a patient's clinical health status, a higher education level and a stable

Osteoporosis has become an emerging comorbid condition in people living with HIV (PLWH). The increase in survival and the progressive aging of PLWH will make this complication more frequent in the near future. In addition to the traditional risk factors affecting the general population, factors directly or indirectly associated with HIV infection, including antiretroviral therapy, can increase the risk of osteoporosis. The present article is an executive summary of the document that updates the previous recommendations on the prevention and treatment of osteoporosis in PLWH. This document is intended for all professionals who work in clinical practice in the field of HIV infection.

For two decades, triple combinations of antiretrovirals have been the standard treatment for HIV infection. The challenges of such lifelong therapy include long-term side effects, high costs and reduced drug adherence. The recent advent of more potent and safer antiretrovirals has renewed the interest for simpler HIV regimens. Areas covered: We discuss the pros and cons of dual antiretroviral therapies in both drug-naïve and in treatment-experienced patients with viral suppression (switch strategy). Expert opinion: Some dual antiretroviral regimens are safe and efficacious, particularly as maintenance therapy. At this time, combinations of dolutegravir plus rilpivirine represent the best dual regimen. Longer follow-up and larger study populations are needed before supporting dolutegravir plus lamivudine. In contrast, dual therapy based on maraviroc is less effective. Although dual regimens with boosted protease inhibitors plus either lamivudine or raltegravir may be effective, they are penalized by metabolic side effects and risk for drug interactions. The newest dual regimens could save money, reduce toxicity and spare drug options for the future. For the first time in HIV therapeutics, less can be more. Dual therapy switching has set up a new paradigm in HIV treatment that uses induction-maintenance.

Type I interferons (IFN), which are immediately induced after most virus infections, are central for direct antiviral immunity and link innate and adaptive immune responses. However, several viruses have evolved strategies to evade the IFN response by preventing IFN induction or blocking IFN signaling pathways. Thus, therapeutic application of exogenous type I IFN or agonists inducing type I IFN responses are a considerable option for future immunotherapies against chronic viral infections. An important part of the type I IFN family are 12 IFNα subtypes, which all bind the same receptor, but significantly differ in their biological activities. Up to date only one IFNα subtype (IFNα2) is being used in clinical treatment against chronic virus infections, however its therapeutic success rate is rather limited, especially during Human Immunodeficiency Virus (HIV) infection. Recent studies addressed the important question if other IFNα subtypes would be more potent against retroviral infections in in vitro and in vivo experiments. Indeed, very potent IFNα subtypes were defined and their antiviral and immunomodulatory properties were characterized. In this review we summarize the recent findings on the role of individual IFNα subtypes during HIV and Simian Immunodeficiency Virus infection. This includes their induction during HIV/SIV infection, their antiretroviral activity and the regulation of immune response against HIV by different IFNα subtypes. The findings might facilitate novel strategies for HIV cure or functional cure studies. Copyright © 2018 Elsevier Ltd. All rights reserved.

This article critically reviews the utility of "phenotypes" as behavioral descriptors in aging/HIV research that inform biological underpinnings and treatment development. We adopt a phenotypic redefinition of aging conceptualized within a broader context of HIV infection and of aging. Phenotypes are defined as dimensions of behavior, closely related to fundamental mechanisms, and, thus, may be more informative than chronological age. Primary emphasis in this review is given to comorbid aging and cognitive aging, though other phenotypes (i.e., disability, frailty, accelerated aging, successful aging) are also discussed in relation to comorbid aging and cognitive aging. The main findings that emerged from this review are as follows: (1) the phenotypes, comorbid aging and cognitive aging, are distinct from each other, yet overlapping; (2) associative relationships are the rule in HIV for comorbid and cognitive aging phenotypes; and (3) HIV behavioral interventions for both comorbid aging and cognitive aging have been limited. Three paths for research progress are identified for phenotype-defined aging/HIV research (i.e., clinical and behavioral specification, biological mechanisms, intervention targets), and some important research questions are suggested within each of these research paths.

HIV-1 enters the CNS soon after peripheral infection and causes chronic neuroinflammation and neuronal damage that leads to cognitive impairment in 40-70% of HIV-infected people. The nonpathogenic cellular isoform of the human prion protein (PrP c ) is an adhesion molecule constitutively expressed in the CNS. Previously, our laboratory showed that shed PrP c (sPrP c ) is increased in the cerebrospinal fluid of HIV-infected people with cognitive deficits as compared with infected people with no impairment. In this article, we demonstrate that CCL2 and TNF-α, inflammatory mediators that are elevated in the CNS of HIV-infected people, increase shedding of PrP c from human astrocytes by increasing the active form of the metalloprotease ADAM10. We show that the consequence of this shedding can be the production of inflammatory mediators, because treatment of astrocytes with rPrP c increased secretion of CCL2, CXCL-12, and IL-8. Supernatants from rPrP c -treated astrocytes containing factors produced in response to this treatment, but not rPrP c by itself, cause increased chemotaxis of both uninfected and HIV-infected human monocytes, suggesting a role for sPrP c in monocyte recruitment into the brain. Furthermore, we examined whether PrP c participates in glutamate uptake and found that rPrP c decreased uptake of this metabolite in astrocytes, which could lead to neurotoxicity and neuronal loss. Collectively, our data characterize mediators involved in PrP c shedding and the effect of this sPrP c on monocyte chemotaxis and glutamate uptake from astrocytes. We propose that shedding of PrP c could be a potential target for therapeutics to limit the cognitive impairment characteristic of neuroAIDS.

Background HIV-infected individuals have deficient responses to Yellow Fever vaccine (YFV) and may be at higher risk for adverse events (AE). Chronic immune activation–characterized by low CD4/CD8 ratio or high indoleamine 2,3-dioxygenase-1 (IDO) activity—may influence vaccine response in this population. Methods We prospectively assessed AE, viremia by the YFV virus and YF-specific neutralizing antibodies (NAb) in HIV-infected (CD4>350) and -uninfected adults through 1 year after vaccination. The effect of HIV status on initial antibody response to YFV was measured during the first 3 months following vaccination, while the effect on persistence of antibody response was measured one year following vaccination. We explored CD4/CD8 ratio, IDO activity (plasma kynurenine/tryptophan [KT] ratio) and viremia by Human Pegivirus as potential predictors of NAb response to YFV among HIV-infected participants with linear mixed models. Results 12 HIV-infected and 45-uninfected participants were included in the final analysis. HIV was not significantly associated with AE, YFV viremia or NAb titers through the first 3 months following vaccination. However, HIV–infected participants had 0.32 times the NAb titers observed for HIV-uninfected participants at 1 year following YFV (95% CI 0.13 to 0.83, p = 0.021), independent of sex, age and prior vaccination. In HIV-infected participants, each 10% increase in CD4/CD8 ratio predicted a mean 21% higher post-baseline YFV Nab titer (p = 0.024). Similarly, each 10% increase in KT ratio predicted a mean 21% lower post-baseline YFV Nab titer (p = 0.009). Viremia by Human Pegivirus was not significantly associated with NAb titers. Conclusions HIV infection appears to decrease the durability of NAb responses to YFV, an effect that may be predicted by lower CD4/CD8 ratio or higher KT ratio. PMID:27941965

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

Full Text Available The level of viral diversity in an HIV-infected individual can change during the course of HIV infection, reflecting mutagenesis during viral replication and selection of viral variants by immune and other selective pressures. Differences in the level of viral diversity in HIV-infected infants may reflect differences in viral dynamics, immune responses, or other factors that may also influence HIV disease progression. We used a novel high resolution melting (HRM assay to measure HIV diversity in Ugandan infants and examined the relationship between diversity and survival through 5 years of age.Plasma samples were obtained from 31 HIV-infected infants (HIVNET 012 trial. The HRM assay was used to measure diversity in two regions in the gag gene (Gag1 and Gag2 and one region in the pol gene (Pol.HRM scores in all three regions increased with age from 6-8 weeks to 12-18 months (for Gag1: P = 0.005; for Gag2: P = 0.006; for Pol: P = 0.016. Higher HRM scores at 6-8 weeks of age (scores above the 75(th percentile were associated with an increased risk of death by 5 years of age (for Pol: P = 0.005; for Gag1/Gag2 (mean of two scores: P = 0.003; for Gag1/Gag2/Pol (mean of three scores: P = 0.002. We did not find an association between HRM scores and other clinical and laboratory variables.Genetic diversity in HIV gag and pol measured using the HRM assay was typically low near birth and increased over time. Higher HIV diversity in these regions at 6-8 weeks of age was associated with a significantly increased risk of death by 5 years of age.

Torque Teno Virus (TTV) is a circular single-stranded DNA virus that may co-infected with human immunodeficiency virus (HIV), especially in the high-risk community e.g. the transgender performing high-riskbehavior. TTV shows an increased viremia in HIV patients and maybe influence the HIV clinical progression. Blood samples collected from transgender performing high-riskbehavior in Surakarta were tested by serological and molecular assays to detect the presence of HIV infection. The blood samples with HIV positive status were then tested by a nested polymerase chain reaction (PCR) to detect the presentation of TTV DNA. The amplified PCR products were molecularly cloned and subjected to sequence analysis. TTV DNA was detected in 40.0% HIV-positive samples. The molecular characterization revealed that the most prevalent was genogroup 3, followed by genogroup 2 and 1, respectively. TTV was detected in HIV-infected transgender performing high-riskbehavior in Surakarta with high infection rate.

Vietnam has an emerging human immunodeficiency virus (HIV) epidemic (estimated population prevalence 0.5%), but valid data on HIV prevalence among tuberculosis (TB) patients are limited. Recent increases in TB notification rates among young adults may be related to HIV. To assess the prevalence of HIV infection among smear-positive TB patients in six provinces with relatively high HIV population prevalence in Vietnam. All patients who registered for treatment of smear-positive TB during the fourth quarter of 2005 were offered HIV testing. Of the 1217 TB patients included in the study, 100 (8.2%) tested HIV-positive. HIV prevalence varied between 2% and 17% in the provinces, and was strongly associated with age Vietnam, HIV infection is concentrated in drug users, as well as in specific geographic areas where it has considerable impact on TB notification rates among men aged 15-34 years.

Objectives. This study estimated the prevalence of violence during pregnancy in relation to HIV infection. Methods. Violence, current partnerships, and HIV risk behaviors were assessed among 336 HIV-seropositive and 298 HIV-seronegative at-risk pregnant women. Results. Overall, 8.9% of women experienced recent violence; 21.5% currently had abusive partners. Violence was experienced by women in all partnership categories (range = 3.8% with nonabusive partners to 53.6% with physically abusive partners). Neither experiencing violence nor having an abusive partner differed by serostatus. Receiving an HIV diagnosis prenatally did not increase risk. Disclosure-related violence occurred, but was rare. Conclusions. Many HIV-infected pregnant women experience violence, but it is not typically attributable to their serostatus. Prenatal services should incorporate screening and counseling for all women at risk for violence. (Am J Public Health. 2002;92:367–370) PMID:11867312

Viral infections, including HIV, trigger the production of type I interferons (IFNs), which in turn, activate a signalling cascade that ultimately culminates with the expression of anti-viral proteins. Mounting evidence suggests that type I IFNs, in particular IFN-α, play a pivotal role in limiting acute HIV infection. Highly active anti-retroviral treatment reduces viral load and increases life expectancy in HIV positive patients; however, it fails to fully eliminate latent HIV reservoirs. To revisit HIV as a curable disease, this article reviews a body of literature that highlights type I IFNs as mediators in the control of HIV infection, with particular focus on the anti-HIV restriction factors induced and/or activated by IFN-α. In addition, we discuss the relevance of type I IFN treatment in the context of HIV latency reversal, novel therapeutic intervention strategies and the potential for full HIV clearance.

HIV-infected individuals are susceptible to development of chronic lung diseases, but little is known regarding the prevalence and risk factors associated with different spirometric abnormalities in this population. We sought to determine the prevalence, risk factors and performance characteristics of risk factors for spirometric abnormalities among HIV-infected individuals. Cross-sectional cohort study. We analyzed cross-sectional US data from the NHLBI-funded Lung-HIV consortium - a multicenter observational study of heterogeneous groups of HIV-infected participants in diverse geographic sites. Logistic regression analysis was performed to determine factors statistically significantly associated with spirometry patterns. A total of 908 HIV-infected individuals were included. The median age of the cohort was 50 years, 78% were men and 68% current smokers. An abnormal spirometry pattern was present in 37% of the cohort: 27% had obstructed and 10% had restricted spirometry patterns. Overall, age, smoking status and intensity, history of Pneumocystis infection, asthma diagnosis and presence of respiratory symptoms were independently associated with an abnormal spirometry pattern. Regardless of the presence of respiratory symptoms, five HIV-infected participants would need to be screened with spirometry to diagnose two individuals with any abnormal spirometry pattern. Nearly 40% of a diverse US cohort of HIV-infected individuals had an abnormal spirometry pattern. Specific characteristics including age, smoking status, respiratory infection history and respiratory symptoms can identify those at risk for abnormal spirometry. The high prevalence of abnormal spirometry and the poor predictive capability of respiratory symptoms to identify abnormal spirometry should prompt clinicians to consider screening spirometry in HIV-infected populations.
Full Text Available Background. Chemotherapy-induced neutropenia (CIN can result in poor tolerance of chemotherapy, leading to dose reductions, delays in therapy schedules, morbidity and mortality. Actively identifying predisposing risk factors before treatment is of paramount importance. We hypothesised that chemotherapy is associated with a greater increase in CIN and its complications in HIV-infected patients than in those who are not infected. Objective. To establish the incidence of CIN in HIV-infected and uninfected patients undergoing chemotherapy. Methods. A retrospective chart review and analysis was conducted in the oncology departments at Inkosi Albert Luthuli Central Hospital and Addington Hospital, Durban, South Africa. The study population consisted of 65 previously untreated women of all ages with stage II - IV breast cancer and known HIV status treated with neoadjuvant chemotherapy from January 2012 to December 2015. Results. HIV-infected patients formed 32.3% of the group, and 95.2% of them were on antiretroviral therapy. The mean age (standard deviation (SD of the cohort was 48.5 (13.2 years (40.6 (9.6 years for the HIV-infected group v. 52.0 (13.1 years for the uninfected group; p<0.001. Ninety-five neutropenia episodes were observed (rate 0.85 per 1 year of follow-up time. Following multivariate adjustment, patients with HIV infection were almost two times more likely to develop CIN (hazard ratio (HR 1.76, 95% confidence interval (CI 1.06 - 2.92; p=0.029. A high baseline absolute neutrophil count (ANC (HR 0.80, 95% CI 0.68 - 0.95; p=0.005 remained significantly associated with protection against CIN. Conclusions. HIV-infected patients were younger than those who were not infected, and presented at a more locally advanced stage of disease. HIV infection was an independent predictor for CIN. HIV-infected patients had an almost two-fold increased risk of developing CIN and developed neutropenia at a much faster rate. A high baseline white cell

Nephropathy in HIV-infected patients has been associated with progression to AIDS and death. The virus, several comorbid conditions and certain medications may contribute to the development and progression of kidney disease. This study analyzed data collected from HIV-infected persons enrolled in a HIV registry in Puerto Rico during January 1998 through September 2006. Demographic factors, clinical manifestations, laboratory findings at enrollment, and antiretroviral therapy (ART) prescriptions were compared between patients with and without kidney disease. Death status and cause of death by December 2006 were also evaluated and compared. The study included 1,283 subjects, 69.0% male, 39.7% injecting drug users, 19.5% hepatitis C infected, 6.5% with diabetes mellitus (DM-2), 11.6% had hypertension (HTN) and 9.0% had kidney disease. Patients with kidney disease had significantly higher (P Puerto Rican HIV-infected patients with nephropathy. Kidney disease preventive strategies that include aggressive control of HIV-infection and chronic medical conditions, such as hypertension and diabetes, are recommend as an approach to reduce this health disparity.

Global trends in HIV infection demonstrate an overall increase in HIV prevalence and substantial declines in AIDS related deaths largely attributable to the survival benefits of antiretroviral treatment. Sub-Saharan Africa carries a disproportionate burden of HIV, accounting for more than 70% of the global burden of infection. Success in HIV prevention in sub-Saharan Africa has the potential to impact on the global burden of HIV. Notwithstanding substantial progress in scaling up antiretroviral therapy (ART), sub-Saharan Africa accounted for 74% of the 1.5 million AIDS related deaths in 2013. Of the estimated 6000 new infections that occur globally each day, two out of three are in sub-Saharan Africa with young women continuing to bear a disproportionate burden. Adolescent girls and young women aged 15-24 years have up to eight fold higher rates of HIV infection compared to their male peers. There remains a gap in women initiated HIV prevention technologies especially for women who are unable to negotiate the current HIV prevention options of abstinence, behavior change, condoms and medical male circumcision or early treatment initiation in their relationships. The possibility of an AIDS free generation cannot be realized unless we are able to prevent HIV infection in young women. This review will focus on the epidemiology of HIV infection in sub-Saharan Africa, key drivers of the continued high incidence, mortality rates and priorities for altering current epidemic trajectory in the region. Strategies for optimizing the use of existing and increasingly limited resources are included.

Time from HIV infection to virological suppression: dramatic fall from 2007 to 2016. We examined the time from HIV infection to virological suppression in MSM who were first diagnosed at Melbourne Sexual Health Centre between 2007 and 2016. Retrospective cohort. Date of infection was imputed from the testing history or serological evidence of recent infection (negative or indeterminate western blot) or baseline CD4 cell count. Date of virological suppression was determined using clinical viral load data. We analysed predictors of diagnosis with serological evidence of recent infection (logistic regression) and time from diagnosis to suppression and from infection to suppression (Cox regression) using demographic, clinical, and behavioral covariates. Between 2007 and 2016, the median time from HIV infection to diagnosis fell from 6.8 to 4.3 months (P = 0.001), from diagnosis to suppression fell from 22.7 to 3.2 months (P < 0.0001), and from infection to suppression fell from 49.0 to 9.6 months (P < 0.0001). Serological evidence of recent infection increased from 15.6 to 34.3% (P < 0.0001) of diagnoses. In the multivariate analyses, age, being recently arrived from a non-English speaking country, history of IDU, other sexually transmitted infections, and sexual risk were not associated with any of these measures. The duration of infectiousness in MSM diagnosed with HIV infection at Melbourne Sexual Health Centre in Victoria has fallen dramatically between 2007 and 2016 and the proportion diagnosed with serological evidence of recent infection has increased. This effect is observed across all population subgroups and marks a positive milestone for the treatment as prevention paradigm.

Global trends in HIV infection demonstrate an overall increase in HIV prevalence and substantial declines in AIDS related deaths largely attributable to the survival benefits of antiretroviral treatment. Sub-Saharan Africa carries a disproportionate burden of HIV, accounting for more than 70% of the global burden of infection. Success in HIV prevention in sub-Saharan Africa has the potential to impact on the global burden of HIV. Notwithstanding substantial progress in scaling up antiretroviral therapy (ART), sub-Saharan Africa accounted for 74% of the 1.5 million AIDS related deaths in 2013. Of the estimated 6000 new infections that occur globally each day, two out of three are in sub-Saharan Africa with young women continuing to bear a disproportionate burden. Adolescent girls and young women aged 15-24 years have up to eight fold higher rates of HIV infection compared to their male peers. There remains a gap in women initiated HIV prevention technologies especially for women who are unable to negotiate the current HIV prevention options of abstinence, behavior change, condoms and medical male circumcision or early treatment initiation in their relationships. The possibility of an AIDS free generation cannot be realized unless we are able to prevent HIV infection in young women. This review will focus on the epidemiology of HIV infection in sub-Saharan Africa, key drivers of the continued high incidence, mortality rates and priorities for altering current epidemic trajectory in the region. Strategies for optimizing the use of existing and increasingly limited resources are included. PMID:27347270
Full Text Available HIV-infected individuals continue to experience neurocognitive deterioration despite virologically successful treatments. While the cause remains unclear, evidence suggests that HIV-associated neurocognitive disorders (HAND may be associated with neurobehavioral dysfunction. Genetic variants have been explored to identify risk markers to determine neuropathogenesis of neurocognitive deterioration. Memory deficits and executive dysfunction are highly prevalent among HIV-infected adults. These conditions can affect their quality of life and HIV risk-taking behaviors. Single nucleotide polymorphisms in the SLC6A4, TPH2, and GALM genes may affect the activity of serotonin and increase the risk of HAND. The present study explored the relationship between SLC6A4, TPH2, and GALM genes and neurocognitive impairment in HIV-infected alcohol abusers. A total of 267 individuals were genotyped for polymorphisms in SLC6A4 5-HTTLPR, TPH2 rs4570625, and GALM rs6741892. To assess neurocognitive functions, the Short Category and the Auditory Verbal Learning Tests were used. TPH2 SNP rs4570625 showed a significant association with executive function in African American males (odds ratio 4.8, 95% CI, 1.5–14.8; P=0.005. Similarly, GALM SNP rs6741892 showed an increased risk with African American males (odds ratio 2.4, 95% CI, 1.2–4.9; P=0.02. This study suggests that TPH2 rs4570625 and GALM rs6741892 polymorphisms may be risk factors for HAND.

Intended and unintended pregnancies occur frequently among HIV-infected women. We evaluated the occurrence of repeat pregnancy and characteristics associated with this outcome among HIV-infected women in Latin America and the Caribbean who were participating in the National Institute of Child Health and Human Development (NICHD) International Site Development Initiative (NISDI). Of the 1342 HIV-infected pregnant women enrolled in NISDI, 124 (9.2%) had one or more repeat pregnancies on study. Median time between the index delivery and date of conception of the subsequent pregnancy was 1.4 years (range 0.1–5.7). Younger age [odds ratio (OR)=1.07, 95% confidence interval (CI): 1.04–1.11 per one-year decrease in age], hospitalization during the index pregnancy or up to 6 months postpartum [OR=2.0, 95% CI: 1.2–3.4], and poor index pregnancy outcome (stillbirth or spontaneous/therapeutic abortion) [OR=3.4, 95% CI: 1.4–8.4] were associated with increased occurrence of repeat pregnancy in multivariable analysis. Among women with repeat pregnancies, the proportion receiving antiretroviral treatment (versus prophylaxis) increased from 39.4% at the time of the index pregnancy to 81.8% at the time of the repeat pregnancy (ppregnancy planning and prevention of unintended pregnancies.

There are limited data on respiratory syncytial virus (RSV) infection among children in settings with a high prevalence of human immunodeficiency virus (HIV). We studied the epidemiology of RSV-associated acute lower respiratory tract infection (ALRTI) hospitalizations among HIV-infected and HIV-uninfected children in South Africa. Children aged infection among HIV-infected and uninfected children were examined. The relative risk of hospitalization in HIV-infected and HIV-uninfected children was calculated in 1 site with population denominators. Of 4489 participants, 4293 (96%) were tested for RSV, of whom 1157 (27%) tested positive. With adjustment for age, HIV-infected children had a 3-5-fold increased risk of hospitalization with RSV-associated ALRTI (2010 relative risk, 5.6; [95% confidence interval (CI), 4.5-6.4]; 2011 relative risk, 3.1 [95% CI, 2.6-3.6]). On multivariable analysis, HIV-infected children with RSV-associated ALRTI had higher odds of death (adjusted odds ratio. 31.1; 95% CI, 5.4-179.8) and hospitalization for >5 days (adjusted odds ratio, 4.0; 95% CI, 1.5-10.6) than HIV-uninfected children. HIV-infected children have a higher risk of hospitalization with RSV-associated ALRTI and a poorer outcome than HIV-uninfected children. These children should be targeted for interventions aimed at preventing severe RSV disease.

The ML frequency, pathogenicity, clinical patterns and possible association with AIDS in Tanzania, are not well documented impeding the development of preventive and therapeutic strategies. Methods Sections of 176 archival formalin-fixed paraffin-embedded biopsies of ML patients at Muhimbili National Hospital (MNH/Muhimbili University of Health and Allied Sciences (MUHAS, Tanzania from 1996–2001 were stained for hematoxylin and eosin and selected (70 cases for expression of pan-leucocytic (CD45, B-cell (CD20, T-cell (CD3, Hodgkin/RS cell (CD30, histiocyte (CD68 and proliferation (Ki-67 antigen markers. Corresponding clinical records were also evaluated. Available sera from 38 ML patients were screened (ELISA for HIV antibodies. Results The proportion of ML out of all diagnosed tumors at MNH during the 6 year period was 4.2% (176/4200 comprising 77.84% non-Hodgkin (NHL including 19.32% Burkitt's (BL and 22.16% Hodgkin's disease (HD. The ML tumors frequency increased from 0.42% (1997 to 0.70% (2001 and 23.7% of tested sera from these patients were HIV positive.

Supra-diaphragmatic presentation was commonest and histological sub-types were mostly aggressive B-cell lymphomas however, no clear cases of primary effusion lymphoma (PEL and primary central nervous system lymphoma (PCNSL were diagnosed. Conclusion Malignant lymphomas apparently, increased significantly among diagnosed tumors at MNH between 1996 and 2001, predominantly among the young, HIV infected and AIDS patients. The frequent aggressive clinical and histological presentation as well as the dominant B-immunophenotype and the HIV serology indicate a pathogenic association with AIDS. Therefore

Full Text Available Cutaneous manifestations of human immunodeficiency virus (HIV disease may result from HIV infection itself, or from opportunistic disorders secondary to the declined immunocompetence due to the disease. A total of 220 HIV positive patients, treated in the Benghazi Center of Infectious Diseases and Immunology over a period of 14 years (January 2003 to November 2016, were included in a retrospective study. The patients' age ranged from 7 to 46 years. The study was conducted by reviewing the patients' records using the management information system (MIS. Statistical analysis of the data was carried out by the t-test and Chi square test. Among the studied patients, 119 (54.1% were males and 101 (45.9% were females, and most of them (78.6% were 10 – 19 years of age. The predominant mode of transmission was parenteral transmission, in 95% of patients, and positive family history was observed in 12% of patients. Among the total number of visits to dermatologists, 93% of patients had a single disease. Of the total number of skin diseases diagnosed during the visits, parasitic infestations were seen in 92 patients (21.0%, eczematous and related disorders in 78 patients (17.8%, viral infections in 71 patients (16.2%, bacterial infections in 41 patients (9.3%, and fungal infections in 35 patients (7.9%. Dermatophyte infections were the most common fungal infections recorded in 19 patients (4.3%, followed by Candida infection in 11 patients (2.5%. Warts were found in 5.9% of viral infections, followed by herpes zoster (4.1%. HIV positive patients should be examined for skin disorders, because early diagnosis and management of such problems improves the quality of life in these patients.

Background: Human immunodefieciency virus (HIV)-infected persons are living longer in the era of effective HIV treatment, resulting in an increasing cancer burden in this population. The combined effects of HIV and cancer on mortality are incompletely understood. Methods: We examined whether individuals with both HIV and cancer have excess mortality using data from the HIV/AIDS Cancer Match Study and the National Center for Health Statistics (1996-2010). We compared age, sex, and race-stratified mortality between people with and without HIV or one of the following cancers: lung, breast, prostate, colorectum, anus, Hodgkin lymphoma, or non-Hodgkin lymphoma. We utilized additive Poisson regression models that included terms for HIV, cancer, and an interaction for their combined effect on mortality. We report the number of excess deaths per 1,000 person-years for models with a significant interaction ( P mortality. Excess mortality was most pronounced at younger ages (30-49 years), with large excesses for males with lung cancer (white race: 573 per 1,000 person-years; non-white: 503) and non-Hodgkin lymphoma (white: 236; non-white: 261), and for females with Hodgkin lymphoma (white: 216; non-white: 136) and breast cancer (non-white: 107). Conclusions: In the era of effective HIV treatment, overall mortality in patients with both HIV and cancer was significantly higher than expected on the basis of mortality rates for each disease separately. Impact: These results suggest that HIV may contribute to cancer progression and highlight the importance of improved cancer prevention and care for the U.S. HIV population.

Full Text Available Background Persistent proteinuria (microalbuminuria has been reported to be a precursor of HIV-related renal disease. Screening allows for early management in order to prevent the progression of renal disease and decrease morbidity and mortality associated with chronic kidney disease in HIV. Several studies have been done on renal manifestation in HIV-infected children from American and African regions, but similar studies from Asia are lacking. Objective To determine the prevalence of persistent proteinuria in HIV-positive children on antiretroviral therapy (ARV in Dr. Soetomo Hospital, Surabaya. Methods A cross-sectional study on children with HIV and treated with highly active antiretroviral therapy (HARRT was done from August 2014 to February 2015. Microalbuminuria was measured by the ratio of urine albumin to creatinine (ACR, while proteinuria was measured by dipstick. Measurements were performed 3 times in 4-8 weeks. All subjects underwent complete evaluation of blood tests, serum creatinine, blood urea nitrogen (BUN, CD4 counts, and urinalysis. Data were analyzed using Chi-square and logistic regression tests. Results Of 38 children on HARRT enrolled in this study, 2 subjects developed acute kidney injury (AKI, 4 subjects were suspected to have urinary tract infection (UTI, and 1 subject was suspected to have urinary tract stones. The prevalence of persistent microalbuminuria was 2.6%. There was no correlation between immunological status, WHO clinical stage, or duration of ARV and the incidence of persistent proteinuria (P>0.05. Conclusion The prevalence of persistent proteinuria is lower in younger HIV-infected children at a non-advanced stage and HIV-infected children with normal immunological status who are on HAART. We provide baseline data on the renal conditions of HIV-infected children in the era of HAART, before tenovofir is increasingly used as an antiretroviral therapy regimen in Indonesia.

Depressive symptoms have been linked to HIV progression through a number of biobehavioral mechanisms including increased alcohol use. Although research supports an association between alcohol use and depressive symptoms among HIV patients, there have been few studies that have examined whether depressive symptoms predict subsequent drinking, especially among heavy drinking HIV-infected patients. Heavy drinking Russian HIV-infected patients (n=700) were recruited from addiction and HIV care settings for a randomized controlled trial of a risk reduction intervention [HERMITAGE]. GEE overdispersed Poisson regression analyses were conducted to assess the association between depressive symptoms and alcohol consumption 6-months later. In adjusted analyses, depressive symptom severity was significantly associated with drinks per day (global p=.02). Compared to the non-depressed category, mild depressive symptoms were significantly associated with more drinks per day [IRR=1.55, (95% CI: 1.14, 2.09)], while moderate [IRR=1.14, (95% CI: 0.83, 1.56)] and severe [IRR=1.48, (95% CI: 0.93, 2.34)] depressive symptoms were not. Associations between depressive symptom severity and heavy drinking days were not statistically significant (global p=.19). Secondary analyses using the BDI-II screening threshold (BDI-II>14) and the BDI-II cognitive subscale suggested an association between depressive symptoms and drinks per day over time but not heavy episodic drinking. Among heavy drinking HIV-infected patients, elevated depressive symptoms were associated with greater subsequent alcohol use. These findings suggest that depressive symptoms may be important to address in efforts to reduce alcohol-related risks among HIV-infected populations. Copyright © 2013 Elsevier Ireland Ltd.

An increasing number of perinatally HIV-infected women (PHIV) are reaching adulthood and becoming pregnant. Most PHIV women have been exposed to a high number of antiretroviral regimens, and they may have difficulties to achieve viral suppression. Psychosocial problems are not uncommon and could be an important barrier for treatment adherence. The effects of chronic HIV infection and long-term exposure to antiretroviral treatment of PHIV women cause concerns on the developing fetus. The aims of this study were to describe the prevention of mother-to-child transmission strategies in PHIV women and the infant outcomes in the Madrid Cohort of HIV-infected mother-infant pairs. All PHIV pregnant women registered in the Cohort that gave birth from 2000 to 2015 were included in the study. Twenty-eight pregnancies in twenty-two perinatally infected women were registered. Most women were Caucasian and heavily treatment-experienced. Nine cases (32.1%) were at high risk of HIV mother-to-child transmission. Maternal HIV-1 viral load was detectable close to delivery in four women (14.3%). The management of these cases was described, and the treatment strategies were discussed. None of the newborns acquired HIV infection. Eight infants (28.6%) were small for gestational age. This study included a large series of pregnancies among PHIV women attended according to a youth-centered care model. The challenges in the management of this population by health-care providers were described. Specific strategies to minimize perinatal transmission risks should be addressed in future collaborative studies.

Full Text Available Diseases of the ENT organs are among the commonly prevalent and dangerous pathologies of childhood, occurring as a complication of respiratory, bacterial diseases and HIV infection. One of the serious complications of HIV infection in children is the lesion of ENT organs. In HIV infected children, in addition to suppurative diseases occur middle ear diseases with nonsuppurative origin. A total of 79 HIV infected children aged 3-14 years with different pathologies of the nasal cavity, nasopharynx and paranasal sinuses were included into the current study. The control group included 20 healthy children of comparable age and sex. The survey was conducted in the ENT department of the Children’s Multi-Medical Center, in Bukhara region. Children with a diagnosis of suppurative otitis media and/or history of suppurative otitis media were not included into the study. All HIV infected children, along with physical examination, were performed ENT examination, finger study, X-ray examination of the paranasal sinuses, audiological research and impedancemetry.

Natural killer T (NKT) cells bridge across innate and adaptive immune responses and have an important role in chronic viral infections such as human immunodeficiency virus (HIV). NKT cells are depleted during chronic HIV infection, but the timing, drivers and implications of this NKT cell depletion are poorly understood. We studied human peripheral blood NKT cell levels, phenotype and function in 31 HIV-infected subjects not on antiretroviral treatment from a mean of 4 months to 2 years after HIV infection. We found that peripheral CD4(+) NKT cells were substantially depleted and dysfunctional by 4 months after HIV infection. The depletion of CD4(+) NKT cells was more marked than the depletion of total CD4(+) T cells. Further, the early depletion of NKT cells correlated with CD4(+) T-cell decline, but not HIV viral levels. Levels of activated CD4(+) T cells correlated with the loss of NKT cells. Our studies suggest that the early loss of NKT cells is associated with subsequent immune destruction during HIV infection.
as ART becomes increasingly available in resource-limited parts of the world. The influence of these, and other factors, on the clinical progression of HIV infection are reviewed in detail, both preceding and following treatment initiation.

Full Text Available Understanding early events of HIV transmission within mucosal tissues is vital for developing effective prevention strategies. Here, we report that primary stromal fibroblasts isolated from endometrium, cervix, foreskin, male urethra, and intestines significantly increase HIV infection of CD4+ T cells-by up to 37-fold for R5-tropic HIV and 100-fold for X4-tropic HIV-without themselves becoming infected. Fibroblasts were more efficient than dendritic cells at trans-infection and mediate this response in the absence of the DC-SIGN and Siglec-1 receptors. In comparison, mucosal epithelial cells secrete antivirals and inhibit HIV infection. These data suggest that breaches in the epithelium allow external or luminal HIV to escape an antiviral environment to access the infection-favorable environment of the stromal fibroblasts, and suggest that resident fibroblasts have a central, but previously unrecognized, role in HIV acquisition at mucosal sites. Inhibiting fibroblast-mediated enhancement of HIV infection should be considered as a novel prevention strategy.
Full Text Available Objectives. Prevalence of hypertension has not been studied in the Ethiopian HIV-infected population, which represents 60% of the patients in our AIDS unit. Our aim was to identify risk factors and characterize the prevalence of hypertension in the population monitored at our unit. Methods. A retrospective chart review categorized subjects according to their blood pressure levels. Hypertension prevalence was determined and stratified according to variables perceived to contribute to elevated blood pressure. Results. The prevalence of hypertension in our study population was significantly higher compared to the general population (53% versus 20%, P<0.0001 and was associated with known risk factors and not with patients’ viral load and CD4 levels. Ethiopian HIV-infected adults had a prominently higher rate of blood pressure rise over time as compared to non-Ethiopians (P=0.016. Conclusions. The high prevalence of hypertension in this cohort and the rapid increase in blood pressure in Ethiopians are alarming. We could not attribute high prevalence to HIV-related factors and we presume it is part of the metabolic syndrome. The lifelong cardiovascular risk associated with HIV infection mandates hypertension screening and close monitoring in this population.

Approximately 71% of HIV-infected individuals live in sub-Saharan Africa. Alcohol use increases unprotected sex, which can lead to HIV transmission. Little research examines risky sex among HIV-infected individuals in East Africa who are not sex workers. The study purpose was to examine associations with unprotected sex in a high-risk sample of 507 HIV-infected sexually active drinkers in western Kenya. They were enrolled in a trial to reduce alcohol use. Past-month baseline alcohol use and sexual behavior were assessed using the Timeline Followback. A zero-inflated negative binomial model examined associations with occurrence and frequency of unprotected sex. Results showed heavy drinking days were significantly associated with unprotected sex occurrence across gender, and with unprotected sex frequency among women. Among women, transactional sex, alcohol-related sexual expectations, condom use self-efficacy, drinking-and-protected-sex days and age were associated with unprotected sex occurrence while alcohol-related sexual expectations, depressive symptoms and condom use self-efficacy were associated with unprotected sex frequency. Among men, alcohol-related sexual expectations, condom use self-efficacy, and age were associated with unprotected sex occurrence, while drinking-and-protected-sex days were associated with unprotected sex occurrence and frequency. Findings suggest robust relationships between heavy drinking and unprotected sex. Further research is needed elucidating the temporal relationships between drinking and unprotected sex in this population.

We evaluated the impact of latent toxoplasmosis (LT) on neurocognitive (NC) and neurobehavioural functioning in young adults with and without chronic HIV infection, using a standardised NC test battery, self-reported Beck Depression Inventory, Frontal System Behavior Scale, MINI-International Neuropsychiatric Interview and risk-assessment battery. 194 young adults (median age 24years, 48.2% males) with chronic HIV infection (HIV+) since childhood and 51 HIV seronegative (HIV-) participants were included. HIV+ individuals had good current immunological status (median CD4: 479 cells/μl) despite a low CD4 nadir (median: 93 cells/μl). LT (positive anti-Toxoplasma IgG antibodies) was present in one third of participants. The impairment rates in the HIV- with and without Toxo were not significantly different (p=0.17). However, we observed an increasing trend (pToxoplasmosis may contribute to NC impairment in young adults, including those with and without chronic HIV infection. Copyright © 2016 Elsevier B.V.

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.

Because treatment failure in many HIV-infected persons may be due to multiple causes, including resistance to antiretroviral agents, it is important to better tailor drug therapy to individual patients. This improvement requires the prediction of treatment outcome from baseline immunological or virological factors, and from results of resistance tests. Here, we review briefly the available clinical factors that have an impact on therapy outcome, and discuss the role of a predictive modelling approach integrating these factors proposed in a previous work. Mathematical and statistical models could become essential tools to address questions that are difficult to study clinically and experimentally, thereby guiding decisions in the choice of individualized drug regimens.

The incidence of lung cancer among individuals infected with the human immunodeficiency virus (HIV) is elevated compared to that among the general population. This study examines the prevalence of HIV and its impact on outcomes among Medicare beneficiaries who are 65 years of age or older and were diagnosed with non small cell lung cancer (NSCLC) between 1997 and 2008. Prevalence of HIV was estimated using the Poisson point estimate and its 95% confidence interval. Relative risks for potential risk factors were estimated using the log-binomial model. A total of 111,219 Medicare beneficiaries met the study criteria. The prevalence of HIV was 156.4 per 100,000 (95% CI: 140.8 to 173.8) and has increased with time. Stage at NSCLC diagnosis did not vary by HIV status. Mortality rates due to all causes were 44%, 76%, and 88% for patients with stage I/II, III, and IV NSCLC, respectively. Across stages of disease, there was no difference between those who were HIV-infected and those who were not with respect to overall mortality. HIV patients, however, were more likely to die of causes other than lung cancer than their immunocompetent counterparts.

Skin biopsies obtained from apparently normal skin from 15 HIV infected patients and 6 anti-HIV negative patients were examined by electron microscopy. Tubuloreticular inclusions (TRI) were detected within the cytoplasm of capillary endothelial cells in 5/5 AIDS patients and in 2/5 patients...... of the patients without TRI, interferon activity was below detection level. The occurrence of TRI was not dependent on the presence of free p24 antigen in serum. It is concluded that the occurrence of TRI in entothelial cells of skin capillaries is associated with late stages of HIV infection and this may...

We conducted a case-control study to assess testosterone use as a primary risk factor for polycythemia in 21 HIV-infected men. Any testosterone use within two months of first elevated hemoglobin was associated with polycythemia (matched odds ratio 6.55; 95% CI 1.83-23.4; P=0.004) and intramuscular administration demonstrated a stronger association than topical use. No adverse cardiovascular or thrombotic events were observed. HIV-infected patients taking testosterone should undergo routine hematologic monitoring with adjustment of therapy when appropriate.

Cardiovascular risk profile was compared in 765 Italian HIV-infected outpatients enrolled in 2005 and in 765 individually age-matched and sex-matched patients enrolled in 2011. Median Framingham risk score was 8.6% in 2005 vs. 7.9% in 2011 (P = 0.04); metabolic syndrome was present in 40.3% vs. 33.4% (P = 0.006). Blood glucose, triglycerides, prevalence of smokers, and lipodystrophy were all significantly lower in 2011 (all P < 0.0001). Cardiovascular risk improved over a 6-year period in Italian HIV-infected patients.

Full Text Available Depression is associated with increased HIV transmission risk, increased morbidity, and higher risk of HIV-related death among HIV-infected women. Low sexual relationship power also contributes to HIV risk, but there is limited understanding of how it relates to mental health among HIV-infected women.Participants were 270 HIV-infected women from the Uganda AIDS Rural Treatment Outcomes study, a prospective cohort of individuals initiating antiretroviral therapy (ART in Mbarara, Uganda. Our primary predictor was baseline sexual relationship power as measured by the Sexual Relationship Power Scale (SRPS. The primary outcome was depression severity, measured with the Hopkins Symptom Checklist (HSCL, and a secondary outcome was a functional scale for mental health status (MHS. Adjusted models controlled for socio-demographic factors, CD4 count, alcohol and tobacco use, baseline WHO stage 4 disease, social support, and duration of ART.The mean HSCL score was 1.34 and 23.7% of participants had HSCL scores consistent with probable depression (HSCL>1.75. Compared to participants with low SRPS scores, individuals with both moderate (coefficient b = -0.21; 95%CI, -0.36 to -0.07 and high power (b = -0.21; 95%CI, -0.36 to -0.06 reported decreased depressive symptomology. High SRPS scores halved the likelihood of women meeting criteria for probable depression (adjusted odds ratio = 0.44; 95%CI, 0.20 to 0.93. In lagged models, low SRPS predicted subsequent depression severity, but depression did not predict subsequent changes in SPRS. Results were similar for MHS, with lagged models showing SRPS predicts subsequent mental health, but not visa versa. Both Decision-Making Dominance and Relationship Control subscales of SRPS were associated with depression symptom severity.HIV-infected women with high sexual relationship power had lower depression and higher mental health status than women with low power.

Full Text Available Markus Gess, Daniel FortonDepartment of Gastroenterology and Hepatology, St George’s University of London, London, UKAbstract: Infection with the human immunodeficiency virus (HIV is associated with a spectrum of neuropsychiatric manifestations ranging from asymptomatic cognitive impairment, detectable only by sensitive neurocognitive tests, to overt HIV-associated dementia. Highly active antiretroviral therapy has led to significant reductions in the incidence of severe HIV-associated dementia. However, the overall prevalence of milder HIV-associated cognitive disorders appears to be increasing as HIV-infected subjects live longer in the era of combined antiretroviral treatments. Chronic hepatitis C virus (HCV infection is also associated with neuropsychological symptoms and impaired cognitive performance in some patients, and recent evidence suggests that these central nervous system (CNS symptoms may be caused by HCV entry into the brain via endothelial infection. Similarly to the neuropathological processes in HIV infection, microglial activation in HCV infected subjects may underlie the CNS metabolic abnormalities and impaired cognitive performance that have been described in studies of HCV-infected cohorts. A significant proportion of HIV-infected subjects are coinfected with HCV, but the impact and clinical importance of coinfection on cognitive function has only been addressed in a small number of research studies. There is some evidence that coinfection may adversely affect neurocognitive function; however, studies published thus far are limited by a number of confounding factors and small sample sizes. This article aims to review the current evidence examining neurocognitive function in HIV- and HCV-monoinfection and further critically discusses previous studies that have explored the impact of coinfection with HCV on CNS function of HIV-infected cohorts. It is clear that, as the population of HIV-infected individuals ages and
Background HIV-associated neurocognitive disorder (HAND) is characterized by development of cognitive, behavioral and motor abnormalities, and occurs in approximately 50% of HIV infected individuals. In the United States, the prevalence of cigarette smoking ranges from 35-70% in HIV-infected individuals compared to 20% in general population. Cognitive impairment in heavy cigarette smokers has been well reported. However, the synergistic effects of nicotine and HIV infection and the underlying mechanisms in the development of HAND are unknown. Results In this study, we explored the role of nicotine in the progression of HAND using SK-N-MC, a neuronal cell line. SK-N-MC cells were infected with HIV-1 in the presence or absence of nicotine for 7 days. We observed significant increase in HIV infectivity in SK-N-MC treated with nicotine compared to untreated HIV-infected neuronal cells. HIV and nicotine synergize to significantly dysregulate the expression of synaptic plasticity genes and spine density; with a concomitant increase of HDAC2 levels in SK-N-MC cells. In addition, inhibition of HDAC2 up-regulation with the use of vorinostat resulted in HIV latency breakdown and recovery of synaptic plasticity genes expression and spine density in nicotine/HIV alone and in co-treated SK-N-MC cells. Furthermore, increased eIF2 alpha phosphorylation, which negatively regulates eukaryotic translational process, was observed in HIV alone and in co-treatment with nicotine compared to untreated control and nicotine alone treated SK-N-MC cells. Conclusions These results suggest that nicotine and HIV synergize to negatively regulate the synaptic plasticity gene expression and spine density and this may contribute to the increased risk of HAND in HIV infected smokers. Apart from disrupting latency, vorinostat may be a useful therapeutic to inhibit the negative regulatory effects on synaptic plasticity in HIV infected nicotine abusers. PMID:24886748

To determine the clinical and epidemiological characteristics of prison inmates with active tuberculosis in HIV-positive prison populations. We conducted a cohort study in HIV-infected subjects in a prison in Mexico City, with the aim of determining clinical and epidemiological characteristics of cases with active TB. We detected 172 HIV infected inmates and TB in 28 of them (16.3%) - 21 (12.2) with pulmonary TB--with an incidence rate of 7.7/100 persons/year for active TB and 4.7/100 persons/year for pulmonary TB. No drug resistance was found. Two clusters (4 and 2 subjects) were observed after RFLP-typing of 18 isolates, with a transmission rate of 11% by molecular and clinical analysis. The prevalence of active TB was found to be a thousand times greater than in the general population. Evidence of transmission inside the prison was also found.

Prevalence rates of low bone mineral density (BMD) and bone fractures are higher among HIV-infected adults compared with the general United States (US) population, but the relationship between BMD and incident fractures in HIV-infected persons has not been well described. Dual energy X-ray absorptiometry (DXA) results of the femoral neck of the hip and clinical data were obtained prospectively during 2004-2012 from participants in two HIV cohort studies. Low BMD was defined by a T-score in the interval >-2.5 to fractures, adjusted for sociodemographics, other risk factors and covariables, using multivariable proportional hazards regression. Among 1,006 participants analysed (median age 43 years [IQR 36-49], 83% male, 67% non-Hispanic white, median CD4(+) T-cell count 461 cells/mm(3) [IQR 311-658]), 36% (n=358) had osteopenia and 4% (n=37) osteoporosis; 67 had a prior fracture documented. During 4,068 person-years of observation after DXA scanning, 85 incident fractures occurred, predominantly rib/sternum (n=18), hand (n=14), foot (n=13) and wrist (n=11). In multivariable analyses, osteoporosis (adjusted hazard ratio [aHR] 4.02, 95% CI 2.02, 8.01) and current/prior tobacco use (aHR 1.59, 95% CI 1.02, 2.50) were associated with incident fracture. In this large sample of HIV-infected adults in the US, low baseline BMD was significantly associated with elevated risk of incident fracture. There is potential value of DXA screening in this population.

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

Objective Maternal nutritional status is an important predictor of birth outcomes, yet little is known about the nutritional status of HIV-infected pregnant women treated with combination antiretroviral therapy (cART). We therefore examined the relationship between maternal BMI at study enrollment, gestational weight gain (GWG), and hemoglobin concentration (Hb) among 166 women initiating cART in rural Uganda. Design Prospective cohort. Methods HIV-infected, ART-naïve pregnant women were enrolled between 12 and 28 weeks gestation and treated with a protease inhibitor or non-nucleoside reverse transcriptase inhibitor-based combination regimen. Nutritional status was assessed monthly. Neonatal anthropometry was examined at birth. Outcomes were evaluated using multivariate analysis. Results Mean GWG was 0.17 kg/week, 14.6% of women experienced weight loss during pregnancy, and 44.9% were anemic. Adverse fetal outcomes included low birth weight (LBW) (19.6%), preterm delivery (17.7%), fetal death (3.9%), stunting (21.1%), small-for-gestational age (15.1%), and head-sparing growth restriction (26%). No infants were HIV-infected. Gaining pregnancy, grossly inadequate GWG was common. Infants whose mothers gained <0.1 kg/week were at increased risk for LBW, preterm delivery, and composite adverse birth outcomes. cART by itself may not be sufficient for decreasing the burden of adverse birth outcomes among HIV-infected women.

Full Text Available Liver disease epidemiology in sub-Saharan Africa has shifted as a result of HIV and the increased use of antiretroviral therapy leading to a need for updated data on common causes of liver disease. We retrospectively reviewed records from all hospitalized patients who had liver biopsy at a single hospital in South Africa from 2001 to 2009 and compared diagnosis by HIV status. During the period of study 262 patients had liver biopsy, 108 (41% were HIV-infected, 25 (10% were HIV-sero-negative, and 129 (49% had unknown or unrecorded HIV status. Overall 81% of biopsies provided additional diagnostic data. Malignancy was the most common finding reported on 56 (21% biopsies followed by granuloma or TB, hepatic steatosis, and fibrosis or cirrhosis. HIV-infected patients were more likely to have granulomas and steatosis. Half of patients with granulomas were already on TB treatment, suggesting paradoxical reactions or drug induced liver injury may have been important causes of liver inflammation among these patients. We note that TB, paradoxical reactions during TB treatment, possible drug induced liver injury, and hepatic steatosis are important causes of liver pathology among HIV-infected hospitalized patients with unclear etiology of liver disease after initial assessment. Among HIV sero-negative patients, malignancy was the major cause of liver disease. Our findings re-enforce the importance of TB as a diagnosis among HIV-infected individuals.

Beliefs about medication necessity and concerns predict treatment adherence in people with a wide-array of medical conditions, including HIV infection. However, medication beliefs have not been examined in people dually treated with psychotropic medications and antiretroviral therapy. In the current study, we used a prospective design to investigate the factors associated with adherence to psychotropic medications and antiretrovirals among 123 dually treated persons living with HIV. We used u...

As perinatal HIV-infected youth become sexually active, the potential for onward transmission becomes an increasing concern. In other populations, intimate partner violence (IPV) is a risk factor for HIV acquisition. We build on this critical work by studying the role of IPV in facilitating onward transmission among HIV-infected youth-an important step toward effective intervention. Soweto, South Africa. Self-report surveys were completed by 129 perinatal HIV-infected female youth (aged 13-24 years). We calculated the IPV prevalence and used logistic models to capture the association between IPV and health outcomes known to facilitate onward HIV transmission (eg, risky sex, poor medication adherence, depression, and substance abuse). A fifth of perinatal HIV-infected participants reported physical and/or sexual IPV in the past year; one-third reported lifetime IPV. Childhood adversity was common and positively associated with IPV. Past-year physical and/or sexual IPV was positively correlated with high-risk sex [odds ratio (OR) = 8.96; 95% confidence interval (CI): 2.78 to 28.90], pregnancy (OR = 6.56; 95% CI: 1.91 to 22.54), poor medication adherence to antiretroviral therapy (OR = 5.37; 95% CI: 1.37 to 21.08), depression (OR = 4.25; 95% CI: 1.64 to 11.00), and substance abuse (OR = 4.11; 95% CI: 1.42 to 11.86). Neither past-year nor lifetime IPV was associated with viral load or HIV status disclosure to a partner. We find that IPV may increase risk for onward HIV transmission in perinatal HIV-infected youth by both increasing engagement in risky sexual behaviors and lowering medication adherence. HIV clinics should consider integrating primary IPV prevention interventions, instituting routine IPV screening, and collocating services for victims of violence.

Full Text Available Sexual transmission of HIV requires exposure to the virus and infection of activated mucosal immune cells, specifically CD4+ T cells or dendritic cells. The foreskin is a major site of viral entry in heterosexual transmission of HIV. Although the probability of acquiring HIV from a sexual encounter is low, the risk varies even after adjusting for known HIV risk factors. The genital microbiome may account for some of the variability in risk by interacting with the host immune system to trigger inflammatory responses that mediate the infection of mucosal immune cells. We conducted a case-control study of uncircumcised participants nested within a randomized-controlled trial of male circumcision in Rakai, Uganda. Using penile (coronal sulcus swabs collected by study personnel at trial enrollment, we characterized the penile microbiome by sequencing and real-time PCR and cytokine levels by electrochemiluminescence assays. The absolute abundances of penile anaerobes at enrollment were associated with later risk of HIV seroconversion, with a 10-fold increase in Prevotella, Dialister, Finegoldia, and Peptoniphilus increasing the odds of HIV acquisition by 54 to 63%, after controlling for other known HIV risk factors. Increased abundances of anaerobic bacteria were also correlated with increased cytokines, including interleukin-8, which can trigger an inflammatory response that recruits susceptible immune cells, suggesting a mechanism underlying the increased risk. These same anaerobic genera can be shared between heterosexual partners and are associated with increased HIV acquisition in women, pointing to anaerobic dysbiosis in the genital microbiome and an accompanying inflammatory response as a novel, independent, and transmissible risk factor for HIV infection.
