    The field of antiretroviral therapy is evolving at a very rapid pace. At this time, the initiation and optimization of antiretroviral therapy is based on serial plasma viral load determinations which aim to suppress viral replication to as low as possible for as long as possible, thus preventing disease progression. Currently available antiretrovirals require combination therapy with at least three agents to achieve this goal. Increasing availability of newer and more potent antiretroviral regimens will continue to enhance and simplify the number of therapeutic options available in the not too distant future.

    The advent of effective combination antiretroviral therapy (ART) in 1996 resulted in fewer patients experiencing clinical events, so that some prognostic analyses of individual cohort studies of human immunodeficiency virus-infected individuals had low statistical power. Because of this, the Antiretroviral Therapy Cohort Collaboration (ART-CC) of HIV cohort studies in Europe and North America was established in 2000, with the aim of studying the prognosis for clinical events in acquired immune deficiency syndrome (AIDS) and the mortality of adult patients treated for HIV-1 infection. In 2002, the ART-CC collected data on more than 12,000 patients in 13 cohorts who had begun combination ART between 1995 and 2001. Subsequent updates took place in 2004, 2006, 2008, and 2010. The ART-CC data base now includes data on more than 70 000 patients participating in 19 cohorts who began treatment before the end of 2009. Data are collected on patient demographics (e.g. sex, age, assumed transmission group, race/ethnicity, geographical origin), HIV biomarkers (e.g. CD4 cell count, plasma viral load of HIV-1), ART regimen, dates and types of AIDS events, and dates and causes of death. In recent years, additional data on co-infections such as hepatitis C; risk factors such as smoking, alcohol and drug use; non-HIV biomarkers such as haemoglobin and liver enzymes; and adherence to ART have been collected whenever available. The data remain the property of the contributing cohorts, whose representatives manage the ART-CC via the steering committee of the Collaboration. External collaboration is welcomed. Details of contacts are given on the ART-CC website (www.art-cohort-collaboration.org). PMID:23599235

    Negative attitudes toward HIV medications may restrict utilization of antiretroviral therapy (ART) in Indonesian prisons where many people living with HIV (PLH) are diagnosed and first offered ART. This mixed-method study examines the influence of medication attitudes on ART utilization among HIV-infected Indonesian prisoners. Randomly-selected HIV-infected male prisoners (n = 102) completed face-to-face in-depth interviews and structured surveys assessing ART attitudes. Results show that although half of participants utilized ART, a quarter of those meeting ART eligibility guidelines did not. Participants not utilizing ART endorsed greater concerns about ART efficacy, safety, and adverse effects, and more certainty that ART should be deferred in PLH who feel healthy. In multivariate analyses, ART utilization was independently associated with more positive ART attitudes (AOR = 1.09, 95 % CI 1.03-1.16, p = 0.002) and higher internalized HIV stigma (AOR = 1.03, 95 % CI 1.00-1.07, p = 0.016). Social marketing of ART is needed to counteract negative ART attitudes that limit ART utilization among Indonesian prisoners. PMID:26400080

    Counselling about antiretroviral therapy (ART) is thought important to prepare patients for treatment and enhance adherence. A workplace-based HIV care programme in South Africa instituted a three-step ART counselling protocol with guidelines prompting issues to be covered at each step. We carried out an early evaluation of ART counselling to determine whether patients understood key information about ART, and the perceptions that patients and health care professionals (HCP) had of the process. Among 40 patients (median time on ART 83 days), over 90% answered 6/7 HIV/ART knowledge-related questions correctly. 95% thought counselling sessions were good. 93% thought ongoing counselling was important. Recommendations included the need for continuing education about HIV/ART, being respectful, promoting HIV testing and addressing the issues of infected partners and stigma. 24 participating HCP identified additional training needs including counselling of family and friends, family planning, sexually transmitted infections and running support groups. 90% of HCP thought that counselling guidelines were helpful. The programme appears to be preparing patients well for ART. Counselling should be offered at every clinic visit. Counselling guidelines were a valuable tool and may be useful elsewhere. The evaluation helped to assess the quality of the programme and to suggest areas for improvement. PMID:16176891

    Improved survival achieved by many patients with HIV/AIDS has complicated their medical care as increasing numbers of co-morbidities leads to polypharmacy, increased pill burdens, and greater risks of drug-drug interactions potentially compromising antiretroviral treatment (ART). We examined the impact of non-antiretroviral polypharmacy on ART for all adults followed at the Southern Alberta Clinic, Calgary, Canada. Polypharmacy was defined as ≥5 daily medications. We compared the impact of polypharmacy on continuous (i.e., remaining on same ART for ≥6 months) vs. non-continuous (i.e., discontinuing or switching ART) ART dosing frequency, number of ART pills, number of non-ART medications, and age. Of 1190 (89.5%) patients on ART, 95% were on three-drug regimens, 63.9% on QD ART, and 62% ≥3 ART pills daily; 32.2% were experiencing polypharmacy. Polypharmacy was associated with lower CD4, AIDS, >180 months living with HIV, higher numbers of ART pills, and older age (all p < 0.01); 32.1% stopped or switched ART. Polypharmacy increased the risk for non-continuous ART (36.8% vs. 30.0%; p < 0.01). Non-continuous ART increased with daily ART pill count but not increased age. Non-adherence and adverse effects accounted for the majority of non-continuous ART. We found a strong association between polypharmacy and non-continuous ART, potentially leading to effective ART being compromised. Collaborative approaches are needed to anticipate the negative impacts of polypharmacy. PMID:26544766

    Background Identifying follow-up (FU) visit patterns, and exploring which factors influence them are likely to be useful in determining which patients on antiretroviral therapy (ART) may become Lost to Follow-Up (LTFU). Using an operation and implementation research approach, we sought 1) to describe the timing of FU visits amongst patients who have been on ART for shorter and longer periods of time; and 2) to determine the median time to late visits, and 3) to identify specific factors that may be associated with these patterns in Zomba, Malawi. Methods and Findings Using routinely collected programme monitoring data from Zomba District, we performed descriptive analyses on all ART visits among patients who initiated ART between Jan. 1, 2007–June 30, 2010. Based on an expected FU date, each FU visit was classified as early (≥4 day before an expected FU date), on time (3 days before an expected FU date/up to 6 days after an expected FU date), or late (≥7 days after an expected FU date). In total, 7,815 patients with 76417 FU visits were included. Ninety-two percent of patients had ≥2 FU visits. At the majority of visits, patients were either on time or late. The median time to a first late visit among those with 2 or more visits was 216 days (IQR: 128–359). Various patient- and visit-level factors differed significantly across Early, On Time, and Late visit groups including ART adherence and frequency of, and type of side effects. Discussion The majority of patients do not demonstrate consistent FU visit patterns. Individuals were generally on ART for at least 6 months before experiencing their first late visit. Our findings have implications for the development of effective interventions that meet patient needs when they present early and can reduce patient losses to follow-up when they are late. In particular, time-varying visit characteristics need further research. PMID:25033285

    Abstract We sought to review the effectiveness of interventions designed to improve adherence to antiretroviral therapy (ART) from studies included in a recent Cochrane review that reported a clinical and an adherence outcome, with at least 80% follow-up for 6 months or more. Data were extracted independently and in duplicate, with an adjudicator for disagreements. Risk of bias was assessed using the Cochrane Risk of Bias tool. Of 182 relevant studies in the Cochrane review, 49 were related to ART. Statistical pooling was not warranted due to heterogeneity in interventions, participants, treatments, adherence measures and outcomes. Many studies had high risk of bias in elements of design and outcome ascertainment. Only 10 studies improved both adherence and clinical outcomes. These used the following interventions: adherence counselling (two studies); a once-daily regimen (compared to twice daily); text messaging; web-based cognitive behavioral intervention; face-to-face multi-session intensive behavioral interventions (two studies); contingency management; modified directly observed therapy; and nurse-delivered home visits combined with telephone calls. Patient-related adherence interventions were the most frequently tested. Uniform adherence measures and higher quality studies of younger populations are encouraged. PMID:25825938

    HIV/AIDS has been an extremely difficult pandemic to control. However, with the advent of antiretroviral therapy (ART), HIV has now been transformed into a chronic illness in patients who have continued treatment access and excellent long-term adherence. Existing indications for ART initiation in asymptomatic patients were based on CD4 levels; however, recent evidence has broken the shackles of CD4 levels. Early initiation of ART in HIV patients irrespective of CD4 counts can have profound positive impact on morbidity and mortality. Early initiation of ART has been found not only beneficial for patients but also to community as it reduces the risk of transmission. There have been few financial concerns about providing ART to all HIV-positive people but various studies have proven that early initiation of ART not only proves to be cost-effective but also contributes to economic and social growth of community. A novel multidisciplinary approach with early initiation and availability of ART at its heart can turn the tide in our favor in future. Effective preexposure prophylaxis and postexposure prophylaxis can also lower transmission risk of HIV in community. New understanding of HIV pathogenesis is opening new vistas to cure and prevention. Various promising candidate vaccines and drugs are undergoing aggressive clinical trials, raising optimism for an ever-elusive cure for HIV. This review describes various facets of tectonic shift in management of HIV. PMID:26900224

    The rapid advances in drug discovery and the development of antiretroviral therapy is unprecedented in the history of modern medicine. The administration of chronic combination antiretroviral therapy targeting different stages of the human immunodeficiency virus' replicative life cycle allows for durable and maximal suppression of plasma viremia. This suppression has resulted in dramatic improvement of patient survival. This article reviews the history of antiretroviral drug development and discusses the clinical pharmacology, efficacy, and toxicities of the antiretroviral agents most commonly used in clinical practice to date.

    Despite being one of the worst affected sectors in South Africa, the mining sector has proven to be one of the most active in intervention efforts in the fight against HIV and AIDS (Ellis, 2007). Owing to low uptake rates of antiretroviral therapy (ART) in mining companies in recent years (Connelly & Rosen, 2006) and the positive relationship between attitudes towards ART and ART uptake (Cooper et al., 2002; Horne, Cooper, Gellaitry, Leake, & Fisher, 2007), this study sought to describe and investigate the psychosocial and behavioural correlates of attitudes towards ART in a sample of South African mineworkers. A total of 806 mineworkers from a large South African mine participated in this quantitative study. Despite a high rate of HIV testing behaviour (83.0%) as well as favourable attitudes towards ART, analysis indicated that temporary employees and contractors were more vulnerable in terms of HIV risk, HIV testing behaviours and ART knowledge and attitudes. Employees who had more positive attitudes towards ART were more knowledgeable of ART and, importantly, had a more favourable attitude towards the mine's HIV/AIDS treatment programme. These findings are discussed in relation to the low ART uptake rates in this context and recommendations for the improvement of ART uptake amongst employees at this mining site. PMID:23237682

    Objective Determine whether HIV and cART affect resting state functional connectivity (rs-fc) between the striatum and cortical regions. Methods 49 HIV uninfected (HIV−) and 132 HIV infected (HIV+) (65% receiving combination anti-retroviral treatment [cART]) had laboratory studies (current and nadir CD4 T-cell counts, and plasma HIV viral load), neuropsychological performance (NP) testing, and neuroimaging. Rs-fc, which examines the coordination of neural activity in distant brain regions, was used to investigate cortico-striatal functional connections. The effect of cART was assessed comparing HIV+ individuals on cART (HIV+/cART+), and HIV+ individuals not currently receiving cART (HIV+/cART−). Relationships between laboratory tests, cognitive performance, and cART on subcortical-cortical rs-fc were assessed by an analysis of variance. Results HIV+ individuals had lower cortico-striatal functional connectivity than HIV− controls, specifically between the striatum and default mode network (DMN; p <0.001) and ventral attention network (VATT; p <0.001). HIV+/cART+ individuals had higher functional connectivity between the striatum and DMN (p=0.02) and VATT (p = 0.01) compared to HIV+/cART− subjects. Laboratory (current and nadir CD4 T-cell counts, plasma viral load) and NP were not correlated with cortico-striatal rs-fc. Conclusions HIV was associated with disrupted cortico-striatal networks, consistent with HIV’s known impact on subcortical areas. Interestingly, within certain networks HIV+/cART+ individuals had similar rs-fc compared to HIV− controls, suggesting possible improvements in HIV related neural dysfunction due to medications. Rs-fc may be a sensitive biomarker of neural insult and its recovery following cART. Additional studies may show rs-fc has utility in measuring acute inflammation caused by HIV. PMID:25849834

    Antiretroviral therapy (ART) has resulted in a substantial improvement in the morbidity and mortality associated with human immunodeficiency virus (HIV) infection. As this population ages, cardiovascular disease is becoming an increasingly important health burden. It is clear that many factors are involved in the development of this problem, with traditional risk factors (smoking, dyslipidemia, diabetes, family history, hypertension) the main contributors. ART and HIV infection itself can modify the risk of cardiovascular disease. Not only does this increased risk seem to be mediated through effects on traditional cardiovascular risk factors, namely dyslipidemia and insulin resistance, but there is also some evidence that HIV and ART may be associated with accelerated atherosclerosis and endothelial dysfunction. Current data are conflicting and further investigation into this area is needed. Drugs from both nucleoside reverse transcriptase inhibitor and protease inhibitor classes have been demonstrated to increase cardiovascular risk; however these effects are variable not only between classes but also between drugs in the same class. As newer therapies become available (in existing and new drug classes), the cardiovascular impact of these will need careful evaluation. Currently published guidelines suggest regular monitoring of cardiovascular risks (both before and after commencing ART) and pre-emptive treatment. Existing risk assessment tools have not been fully validated in an HIV setting and need to be used with caution. Lifestyle modification, in the first instance, and pharmacological intervention to reduce traditional risk factors are important management strategies. Initiating, or switching to, ART with a lower potential for metabolic derangement should also be considered. PMID:19940610

    Purpose of review The purpose of this review was to summarize recent studies on the effect of early antiretroviral therapy (ART) in HIV-infected patients on markers of immune activation/inflammation, viral persistence and serious non-AIDS events. Recent findings Early ART, initiated within days to months of HIV infection, was associated with marked reduction in T-cell activation often reaching levels observed in HIV-uninfected individuals. However, the impact of early ART on markers of innate immune activation, microbial translocation and inflammation/coagulation was less clear. Early ART has also been associated with a significant reduction in the frequency of latently infected cells, which was greater if ART was initiated within days to weeks rather than months following infection. However, few studies have evaluated the relationship between immune activation and viral reservoirs, specifically following early ART. Early ART may potentially reduce serious non-AIDS events and associated mortality, but most of these studies have extrapolated from changes in surrogate markers, such as CD4 : CD8 ratio. Summary Early ART was associated with beneficial effects on multiple markers of immune activation, inflammation and viral persistence. Longer term prospective studies are still needed to determine whether early ART translates to a significant reduction in serious non-AIDS events and mortality. PMID:25415420

    Objectives HIV-induced immunodeficiency is associated with metabolic abnormalities and systemic inflammation. We investigated the effect of antiretroviral therapy (ART) on restoration of insulin sensitivity, markers of immune activation and inflammation. Methods Immunological, metabolic and inflammatory status was assessed at antiretroviral therapy initiation and three years later in 208 patients from the ANRS-COPANA cohort. Patients were compared according to their pre-ART CD4+ cell count (group 1: ≤ 200/mm3, n = 66 vs. group 2: > 200/mm3, n = 142). Results Median CD4+ cell count increased in both groups after 3 years of successful ART but remained significantly lower in group 1 than in group 2 (404 vs 572 cells/mm3). Triglyceride and insulin levels were higher or tended to be higher in group 1 than in group 2 at ART initiation (median: 1.32 vs 0.97 mmol/l, p = 0.04 and 7.6 vs 6.8 IU, p = 0.09, respectively) and remained higher after three years of ART (1.42 vs 1.16 mmol/L, p = 0.0009 and 8.9 vs 7.2 IU, p = 0.01). After adjustment for individual characteristics and antiretroviral therapy regimens (protease inhibitor (PI), zidovudine), insulin levels remained significantly higher in patients with low baseline CD4+ cell count. Baseline IL-6, sCD14 and sTNFR2 levels were higher in group 1 than in group 2. Most biomarkers of immune activation/inflammation declined during ART, but IL-6 and hsCRP levels remained higher in patients with low baseline CD4+ cell count than in the other patients (median are respectively 1.4 vs 1.1 pg/ml, p = 0.03 and 2.1 vs 1.3 mg/ml, p = 0.07). Conclusion After three years of successful ART, low pretreatment CD4+ T cell count remained associated with elevated insulin, triglyceride, IL-6 and hsCRP levels. These persistent metabolic and inflammatory abnormalities could contribute to an increased risk of cardiovascular and metabolic disease. PMID:26636578

    Antiretroviral therapy (ART) is known for its side effects. In this paper, we describe ART side effects as experienced by Chinese HIV+ individuals. This study presents two stages of a research project, combining qualitative in-depth interviews (29 HIV+ participants) with quantitative statistical data analysis (N = 120). All data was collected between July 2005 to March 2008 at Beijing's Ditan Hospital. Consent was obtained from each participant for the qualitative interview and again for the quantitative survey. During in-depth interviews, Chinese HIV+ patients reported experiencing digestive discomfort, skin rashes, numbness, memory loss, nightmares, and dizziness, which not only brought them physical discomfort, but also interrupted different dimensions of their social lives. Furthermore, multiple regression analyses revealed that those who reported more severe side effects also experienced greater depressive mood after controlling for other clinical and psychosocial factors. ART side effects are one of the primary reasons causing HIV+ individuals to delay or stop taking life-saving medication; therefore, clinical interventions are critically needed to assist HIV+ individuals in managing ART side effects. ART side effects reinforced existing negative attitudes toward ART and lead to lower ART adherence. Future research should focus on developing culturally sensitive interventions to enhance HIV+ self-management, to alleviate physical and psychological burden from ART and HIV. PMID:24083060

    Background Short-term zidovudine monotherapy (ZDVm) remains an option for some pregnant HIV-positive women not requiring treatment for their own health but may affect treatment responses once antiretroviral therapy (ART) is subsequently started. Methods Data were obtained by linking two UK studies: the UK Collaborative HIV Cohort (UK CHIC) study and the National Study of HIV in Pregnancy and Childhood (NSHPC). Treatment responses were assessed for 2028 women initiating ART at least one year after HIV-diagnosis. Outcomes were compared using logistic regression, proportional hazards regression or linear regression. Results In adjusted analyses, ART-naïve (n = 1937) and ZDVm-experienced (n = 91) women had similar increases in CD4 count and a similar proportion achieving virological suppression; both groups had a low risk of AIDS. Conclusions In this setting, antenatal ZDVm exposure did not adversely impact on outcomes once ART was initiated for the woman’s health. PMID:24593018

    Abstract Background Effective contraceptive practices amongst HIV-positive women of reproductive age have been shown to reduce mother-to-child transmission of HIV by preventing unplanned pregnancies. However, most antiretroviral therapy (ART) programmes focus on treatment, neglecting comprehensive contraceptive services. This results in a high frequency of pregnancies amongst HIV-positive women attending the ART clinic of a regional hospital north of Durban. Objectives This research aimed to explore contraceptive use amongst HIV-positive women attending an ART clinic by determining, (1) prevalence of contraceptive use, (2) pregnancy rate, (3) contraceptive preferences and (4) factors associated with contraceptive use. Methods In this observational, analytical, cross-sectional study of 420 women, aged 15 to 49 years, participants were selected by systematic random sampling. They completed standardised questionnaires. Results Of all participants, 95% of the participants used contraception. Factors associated with contraceptive practice were knowledge of HIV status 292 (72.8%), health worker advice 84 (20.9%), and spousal insistence 33 (8.2%). Of the 130 women (31%) who had fallen pregnant whilst on ART, 73 (56.2%) said that the pregnancy had been unplanned, whilst 57 (43.8%) had wanted to fall pregnant because of: partner's insistence (45.6%), desire for a child (36.8%), desire to conceal HIV status (15.8%), not wanting to die childless (5.3%), and death of a previous child (1.8%). Conclusion Contraceptive use amongst these women was high but the number of pregnancies is a cause for concern. Information regarding contraceptive use should therefore be provided at all ART clinics.

    Objective To evaluate the association of bone turnover biomarkers with blood levels of alkaline phosphatase (ALP), bone-specific alkaline phosphatase (BAP), osteocalcin (OC), tartrate-resistant acid phosphatase (TRAP), parathyroid hormone (PTH), and other blood markers in HIV-1 infected men receiving anti-retroviral therapy (ART). Advances in the treatment of HIV-1 infection have extended the life span of HIV-1 infected individuals. However, these advances may come at the price of metabolic side effects and bone disorders, including premature osteopenia, osteoporosis and osteonecrosis. Methods Analyses of Ostase BAP, osteocalcin, and TRAP in blood were measured in three groups of MACS participants: 35 HIV-1 infected men on ART (A); 35 HIV-1- infected men not on ART (B); and 34 HIV-1 uninfected men (C). Results The mean and standard deviation results for groups A, B, and C were 19.7 ± 6.56, 17.2 ± 3.96, and 16.9 ± 5.78 for ostase BAP; 7.9 ± 9.53, 8.5 ± 8.30, and 5.5 ± 1.65 for osteocalcin; and 3.9 ± 1.04, 3.1 ± 0.81, and 2.5 ± 0.59 for TRAP, respectively. Simple and multivariate analyses showed significant differences in mean TRAP and BAP concentrations between the three groups. In addition strong correlations between blood levels of Ostase BAP and TRAP (r=0.570, p=0.0004), and between blood levels of Ostase BAP and PTH (r=0.436, P=0.0098) for HIV-1 infected men on ART were observed. Conclusion New strategies for measurement of blood and urine biochemical markers of bone formation and resorption during bone turnover can be useful for clinical monitoring of treatment of HIV-1 infected patients. Recently developed methods for measuring serum levels of TRAP and Ostase BAP represent superior laboratory tools for assessing the hyperactivity of osteoclasts, osteoblasts and bone loss in HIV-1 infected individuals receiving ART. Measurements of TRAP and BAP as bone turnover biomarkers are economical and are important for monitoring bone metabolism during ART and

    With rational use of antiretroviral therapy (ART), human immunodeficiency virus (HIV) infection has been transformed into a chronic manageable illness like diabetes and hypertension. These guidelines provide information on state of art, evidence based approach for use of ART in Indian context. When to initiate ART? Antiretroviral therapy is indicated for all symptomatic HIV infected persons regardless of CD4 counts and plasma viral load (PVL) levels. In asymptomatic patients, ART should be offered when the CD4 counts < 200/mm3 and should be considered in patients with CD4 counts between 200-250/mm3. Therapy is not recommended for patients with CD4 count more than 350/ mm3. Involvement of patient in all treatment decisions and assessing readiness is critical before initiating ART. What to start with? A non-nucleoside reverse transcriptase inhibitor (NNRTI) based regimen is recommended for antiretroviral naïve patients. The choice between nevirapine and efavirenz is based on differences in adverse events profiles; cost and availability of convenient fixed dose combinations and need for concomitant use of rifampicin. A backbone of 2-nucleoside reverse transcriptase inhibitors (NRTIs) is combined with the NNRTI. Various combinations and ART strategies not to be used in clinical practice has been enlisted. How to follow up? Recommendations have been made for baseline evaluation and monitoring of patients on ART. These include guidelines on laboratory and clinical evaluation. A plasma viral load at 6 months after initiation of first-line ART is strongly recommended. Yearly estimation of lipid profile has been recommended. How to identify and manage ART failure? The guidelines recognize the issue of identifying ART failure late if only CD4 counts are used for monitoring. In the absence of resistance testing various second-line regimens have been enlisted. A boosted protease inhibitor based regimen is recommended in this situation to be combined with 2-NRTIs. Special

    Introduction As patients with HIV live longer due to Combination Anti-Retroviral Therapy (cART) serostatus disclosure becomes an important issue. Disclosure can have both positive and negative outcomes. Disclosure of HIV status has been associated with better adherence to medication and reduction in levels of psychological distress. Stigma and disruption of family relationships are barriers for disclosure. Most studies regarding disclosure status have been conducted in West. There are many cultural differences in Indian society when compared to west. There is a dearth of research in the field of disclosure of HIV infection in India. Aim To determine the prevalence of HIV status disclosure among people living with HIV (PLHIV) in South India. Materials and Methods This descriptive cross-sectional study was done in the hospital attached to Kasturba Medical College (KMC), Mangalore, India from May–June 2013. PLHIV of age more than 18 years were included. During the study period 111 consecutive patients who consented for the study were enrolled. Statistical Analysis Data was collected using a pre-tested interviewer administered semi structured questionnaire. Data collected was analysed using SPSS Version 11.5 statistical software. Descriptive statistics were done and the results are presented as proportions and mean. Results The mean age of the study population was 44.86 ± 10.8 years. Majority of the study subjects were men 76 (68.4%). Out of 111 study subjects, 102 (91.9%) had disclosed their HIV status to at least one person while 9 (8.1%) had not disclosed their HIV status to anyone. Disclosure on doctor’s advice was the main reason for 56 (54.9%) participants to disclose their HIV status. The main reason for non-disclosure was fear of shame in family. Conclusion Disclosure rate was high in our study in the era of cART. Society must stop discriminating against PLHIV so that they can disclose their serostatus and gain access to care and treatment services without

    Background.  Antiretroviral therapy (ART) has reduced the rates and changed the causes of hospital admission. However, human immunodeficiency virus-positive intravenous drug users (HIV-IDU) continue to have increased hospitalizations and discharge diagnosis are less defined in the late ART era. Our aim was to examine ART use, HIV-1 RNA suppression, and hospital discharge diagnoses among HIV-IDU admitted to an urban hospital. Methods.  A retrospective analysis was made of HIV-IDU admitted for medical causes for the first time (2006–2010). Surgical, obstetric, or mental (except HIV-associated neurocognitive disorder) diagnoses were excluded. Clinical characteristics, number of admissions, and primary discharge diagnoses were determined for each patient. Results.  Three hundred and seventy-five admissions were recorded among 197 hospitalized HIV-IDU. Lifetime prevalence of ART use was 83.2% (164 of 197) and the rate of HIV-1 RNA <50 copies/mL was 38.1% (75 of 197). Primary discharge diagnosis groups were as follows: bacterial infections (59.2%), chronic end-organ damage (16.8%), complications derived from injected drug use (16.8%), malignancies (9.1%), and opportunistic infections (6.6%). Chronic end-organ damage was diagnosed more frequently in patients with HIV-1 RNA <50 copies/mL (36% vs 4.9%; P < .000), and complications derived from injected drug use (23.8% vs 5.3%; P < .0008) and acquired immune deficiency syndrome (AIDS) opportunistic infections (19.8% vs 1.3% P < .019) were usually diagnosed in patients with HIV-1 RNA detectable viral load. Conclusions.  Human immunodeficiency virus-positive intravenous drug users are admitted to hospitals mainly for non-AIDS-related illnesses; however, sustained HIV-1 RNA viral load suppression is poor and determines hospital discharge diagnoses. Providers need to be aware of the management of HIV-related comorbidities and reinforce strategies to improve ART retention in this population. PMID:25734084

    Background Initiation of antiretroviral therapy (ART) in the advanced stages of HIV infection remains a major challenge in sub-Saharan Africa. This study was conducted to better understand barriers and enablers to timely ART initiation in Rwanda where ART coverage is high and national ART eligibility guidelines first expanded in 2007–2008. Methods Using data on 6326 patients (≥15 years) at five Rwandan clinics, we assessed trends and correlates of CD4+ cell count at ART initiation and the proportion initiating ART with advanced HIV disease (CD4+ <200 cells/µl or WHO stage IV). Results Out of 6326 patients, 4486 enrolling in HIV care initiated ART with median CD4+ cell count of 211 cells/µl [interquartile range: 131–300]. Median CD4+ cell counts at ART initiation increased from 183 cells/µl in 2007 to 293 cells/µl in 2011–2012, and the proportion with advanced HIV disease decreased from 66.2 to 29.4%. Factors associated with a higher odds of advanced HIV disease at ART initiation were male sex [adjusted odds ratios (AOR) = 1.7; 95% confidence interval (CI): 1.3–2.1] and older age (AOR46–55+ vs. <25 = 2.3; 95% CI: 1.2–4.3). Among those initiating ART more than 1 year after enrollment in care, those who had a gap in care of 12 or more months prior to ART initiation had higher odds of advanced HIV disease (AOR = 5.2; 95% CI: 1.2–21.1). Conclusion Marked improvements in the median CD4+ cell count at ART initiation and proportion initiating ART with advanced HIV disease were observed following the expansion of ART eligibility criteria in Rwanda. However, sex disparities in late treatment initiation persisted through 2011–2012, and appeared to be driven by later diagnosis and/or delayed linkage to care among men. PMID:25562492

    Understanding alterations in HIV-specific immune responses during antiretroviral therapy (ART), such as antibody-dependent cellular cytotoxicity (ADCC), is important in the development of novel strategies to control HIV-1 infection. This study included 53 HIV-1 positive individuals. We evaluated the ability of effector cells and antibodies to mediate ADCC separately and in combination using the ADCC-PanToxiLux assay. The ability of the peripheral blood mononuclear cells (PBMCs) to mediate ADCC was significantly higher in individuals who had been treated with ART before seroconversion, compared to the individuals initiating ART at a low CD4+ T cell count (<350 cells/μl blood) and the ART-naïve individuals. The frequency of CD16 expressing natural killer (NK) cells correlated with both the duration of ART and Granzyme B (GzB) activity. In contrast, the plasma titer of antibodies mediating ADCC declined during ART. These findings suggest improved cytotoxic function of the NK cells if initiating ART early during infection, while the levels of ADCC mediating antibodies declined during ART. PMID:26696395

    Background Despite global progress in the fight to reduce maternal mortality, HIV-related maternal deaths remain persistently high, particularly in much of Africa. Lifelong antiretroviral therapy (ART) appears to be the most effective way to prevent these deaths, but the rates of three key outcomes—ART initiation, retention in care, and long-term ART adherence—remain low. This systematic review synthesized evidence on health systems factors affecting these outcomes in pregnant and postpartum women living with HIV. Methods Searches were conducted for studies addressing the population of interest (HIV-infected pregnant and postpartum women), the intervention of interest (ART), and the outcomes of interest (initiation, adherence, and retention). Quantitative and qualitative studies published in English since January 2008 were included. A four-stage narrative synthesis design was used to analyze findings. Review findings from 42 included studies were categorized according to five themes: 1) models of care, 2) service delivery, 3) resource constraints and governance challenges, 4) patient-health system engagement, and 5) maternal ART interventions. Results Low prioritization of maternal ART and persistent dropout along the maternal ART cascade were key findings. Service delivery barriers included poor communication and coordination among health system actors, poor clinical practices, and gaps in provider training. The few studies that assessed maternal ART interventions demonstrated the importance of multi-pronged, multi-leveled interventions. Conclusions There has been a lack of emphasis on the experiences, needs and vulnerabilities particular to HIV-infected pregnant and postpartum women. Supporting these women to successfully traverse the maternal ART cascade requires carefully designed and targeted interventions throughout the steps. Careful design of integrated service delivery models is of critical importance in this effort. Key knowledge gaps and research

    The pathogenesis of HIV infection and the general principles of therapy are the same for HIV-infected adults, adolescents, children and infants. However, antiretroviral treatment of HIV infection in pediatrics requires the consideration of a number of factors specific to its population, including differences in drug pharmacokinetics and the use of virologic and immunologic markers, as well as age-related adherence issues. This review summarizes the text of the Guidelines for the Use of Antiretroviral Agents in Pediatric HIV Infection, which was updated in October 2006. The guidelines are the work of the Working Group on Antiretroviral Therapy and Medical Management of HIV-Infected Children, a group of the Office of AIDS Research Advisory Council of the National Institutes of Health, which reviews new data on an ongoing basis and provides regular updates to the guidelines. As these guidelines were developed for the US, they may not be applicable in other countries. This summary does not attempt to place the Working Group guidelines in the context of international guidelines, nor does it attempt to detail the use of antiretroviral medication in the prevention of perinatal transmission of HIV, such as addressing the use of zidovudine versus single-dose nevirapine.

    Background Combination antiretroviral therapy (ART) for HIV-1 infected individuals prevents sexual transmission if viral load is suppressed. Methods Participants were HIV-1 infected partners randomized to early ART (CD4 350-550) in HPTN052 (n=886, median follow-up = 2.1 years), a clinical trial of early ART to prevent sexual transmission of HIV-1 in serodiscordant couples at 13 sites in 9 countries. Adherence was assessed via pill-count (dichotomized at <95%) and via self-report items. Predictors of adherence were mental health and general health perceptions, substance use, binge drinking, social support, sexual behaviors, and demographics. Viral suppression was defined as HIV plasma viral load <400 copies/ml. Adherence counseling and couples counseling about safer sex was provided. Logistic and linear regression models using generalized estimating equation for repeated measurements were employed. Findings Via pill-count, 82% of participants were adherent at 1 month and 83.3% at 1 year. Mental health was the only psychosocial variable associated with adherence (pill-count OR=1.05: 95% CI: 1.00 – 1.11; self-report parameter estimate (b)=0.02, 95% CI: 0.01 –0.04), though regional differences emerged. Pill-count (OR=1.19, 95% CI: 1.10-1.30) and self-report (OR=1.42, 95% CI: 1.14-1.77) adherence were associated with viral suppression. Interpretation While adherence was high among individuals in stable relationships taking ART for prevention, mental health and adherence co-varied. Assessing and intervening on mental health in the context of promoting adherence to ART as prevention should be explored. Adherence and couples counseling, feedback about viral suppression, and/or altruism may also help explain the magnitude of adherence observed. PMID:26009832

    Global expansion of antiretroviral therapy (ART) programmes for people living with HIV is the largest public health undertaking to date. Antiretroviral therapy adherence drives individual and programme outcomes, yet little is known regarding the determinants of these behaviours. We investigated beliefs and practices associated with ART use in Cambodia. In-depth interviews were conducted during 2005 with 27 people living with HIV who were recruited using a theoretical sampling strategy and analysed in Khmer and English using an inductive approach to code data and identify themes. Limited access to ART generated a sense of ART as rare and precious, with access granted by doctors once patients proved themselves dependable. The social construction of ART use was strict, precise and modern with ritualistic preparation and dosing procedures. Experiences of life-saving efficacy in self and others built a deep sense of trust. For many, ART was simply equated to life. Antiretroviral therapy dosing was prioritized and supported by an ever-present sense of remembering, reminder devices and social networks. Healthcare workers set norms and provided various forms of adherence support. Antiretroviral therapy use in Cambodia is shaped by the relationship between individuals and social and healthcare networks that set, encourage and enforce precise norms of ART use. PMID:21516534

    Background Around 70% of those living with HIV in need of treatment accessed antiretroviral therapy (ART) in Zambia by 2009. However, sustaining high levels of adherence to ART is a challenge. This study aimed to identify the predictive factors associated with ART adherence during the early months of treatment in rural Zambia. Methods This is a field based observational longitudinal study in Mumbwa district, which is located 150 km west of Lusaka, the capital of Zambia. Treatment naive patients aged over 15 years, who initiated treatment during September-November 2010, were enrolled. Patients were interviewed at the initiation and six weeks later. The treatment adherence was measured according to self-reporting by the patients. Multiple logistic regression analysis was performed to identify the predictive factors associated with the adherence. Results Of 157 patients, 59.9% were fully adherent to the treatment six weeks after starting ART. According to the multivariable analysis, full adherence was associated with being female [Adjusted Odds Ratio (AOR), 3.3; 95% Confidence interval (CI), 1.2-8.9], having a spouse who were also on ART (AOR, 4.4; 95% CI, 1.5-13.1), and experience of food insufficiency in the previous 30 days (AOR, 5.0; 95% CI, 1.8-13.8). Some of the most common reasons for missed doses were long distance to health facilities (n = 21, 53.8%), food insufficiency (n = 20, 51.3%), and being busy with other activities such as work (n = 15, 38.5%). Conclusions The treatment adherence continues to be a significant challenge in rural Zambia. Social supports from spouses and people on ART could facilitate their treatment adherence. This is likely to require attention by ART services in the future, focusing on different social influences on male and female in rural Zambia. In addition, poverty reduction strategies may help to reinforce adherence to ART and could mitigate the influence of HIV infection for poor patients and those who fall into poverty after

    Background The use of combination antiretroviral therapy (cART) comprising three antiretroviral medications from at least two classes of drugs is the current standard treatment for HIV infection in adults and children. Current World Health Organization (WHO) guidelines for antiretroviral therapy recommend early treatment regardless of immunologic thresholds or the clinical condition for all infants (less than one years of age) and children under the age of two years. For children aged two to five years current WHO guidelines recommend (based on low quality evidence) that clinical and immunological thresholds be used to identify those who need to start cART (advanced clinical stage or CD4 counts ≤ 750 cells/mm3 or per cent CD4 ≤ 25%). This Cochrane review will inform the current available evidence regarding the optimal time for treatment initiation in children aged two to five years with the goal of informing the revision of WHO 2013 recommendations on when to initiate cART in children. Objectives To assess the evidence for the optimal time to initiate cART in treatment-naive, HIV-infected children aged 2 to 5 years. Search methods We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, the AEGIS conference database, specific relevant conferences, www.clinicaltrials.gov, the World Health Organization International Clinical Trials Registry platform and reference lists of articles. The date of the most recent search was 30 September 2012. Selection criteria Randomised controlled trials (RCTs) that compared immediate with deferred initiation of cART, and prospective cohort studies which followed children from enrolment to start of cART and on cART. Data collection and analysis Two review authors considered studies for inclusion in the review, assessed the risk of bias, and extracted data on the primary outcome of death from all causes and several secondary outcomes, including incidence of CDC category C and B clinical events and

    Introduction Although AIDS-related deaths have had significant economic and social impact following an increased disease burden internationally, few studies have evaluated the cause of AIDS-related deaths among patients with AIDS on combination anti-retroviral therapy (cART) in China. This study examines the causes of death among AIDS-patients in China and uses a methodology to increase data accuracy compared to the previous studies on AIDS-related mortality in China, that have taken the reported cause of death in the National HIV Registry at face-value. Methods Death certificates/medical records were examined and a cross-sectional survey was conducted in three provinces to verify the causes of death among AIDS patients who died between January 1, 2010 and June 30, 2011. Chi-square analysis was conducted to examine the categorical variables by causes of death and by ART status. Univariate and multivariate logistic regression were used to evaluate factors associated with AIDS-related death versus non-AIDS related death. Results This study used a sample of 1,109 subjects. The average age at death was 44.5 years. AIDS-related deaths were significantly higher than non-AIDS and injury-related deaths. In the sample, 41.9% (465/1109) were deceased within a year of HIV diagnosis and 52.7% (584/1109) of the deceased AIDS patients were not on cART. For AIDS-related deaths (n = 798), statistically significant factors included CD4 count <200 cells/mm3 at the time of cART initiation (AOR 1.94, 95%CI 1.24–3.05), ART naïve (AOR 1.69, 95%CI 1.09–2.61; p = 0.019) and age <39 years (AOR 2.96, 95%CI 1.77–4.96). Conclusion For the AIDS patients that were deceased, only those who initiated cART while at a CD4 count ≥200 cells/mm3 were less likely to die from AIDS-related causes compared to those who didn’t initiate ART at all.

    Background We previously reported that integrating antiretroviral therapy (ART) with tuberculosis treatment reduces mortality. However, optimal time to initiate ART during tuberculosis treatment remains contentious. Methods To address this, we conducted a 3-arm, open-label randomized controlled trial in South Africa in acid-fast bacilli smear positive patients (n=642) with HIV and CD4+ counts <500 cells/mm3. Findings on the early therapy group (ART initiated within 4 weeks of tuberculosis treatment initiation, n=214) and late therapy group (ART initiated within the first 4 weeks of the continuation phase of tuberculosis treatment, n=215) are presented here. Results Median CD4+ count and viral load at baseline was 150 cells/mm3 and 161000 copies/ml, being similar in both groups. Incidence rate of AIDS or death was 6.9 (18/259.4) and 7.8 (19/244.2) per 100 person-years in the early and late therapy groups respectively (Incidence Rate Ratio (IRR)=0.89; 95%Confidence Interval (95%CI): 0.44,1.79; P=0.73). However, in patients with CD4+ counts <50 cells/mm3, the incidence rates of AIDS or death were 8.5 (early) and 26.3 (late) per 100 person-years (IRR=0.32; 95%CI: 0.07,1.13; P=0.06). Immune reconstitution inflammatory syndrome (IRIS) incidence rates were 20.2 (early) and 7.7 (late) per 100 person-years (IRR=2.62; 95%CI: 1.48,4.82; P<0.001). Adverse events requiring antiretroviral drug switches occurred in 10 (early) and 1 (late) patients (P=0.006). Conclusions The benefits of AIDS-free survival balanced against the risks of IRIS and ART-related adverse events, support early ART initiation in patients with CD4+ counts <50 cells/mm3 and deferred ART initiation to the continuation phase of tuberculosis treatment when CD4+ counts are higher.

    Background We systematically reviewed observational studies of early mortality post-antiretroviral therapy (ART) initiation in low- and middle-income countries (LMIC) in Asia, Africa, and Central and South America, as defined by the World Bank, to summarize what is known. Methods and Findings Studies published in English between January 1996 and December 2010 were searched in Medline and EMBASE. Three independent reviewers examined studies of mortality within one year post-ART. An article was included if the study was conducted in a LMIC, participants were initiating ART in a non-clinical trial setting and were ≥15 years. Fifty studies were included; 38 (76%) from sub-Saharan Africa (SSA), 5 (10%) from Asia, 2 (4%) from the Americas, and 5 (10%) were multi-regional. Median follow-up time and pre-ART CD4 cell count ranged from 3–55 months and 11–192 cells/mm3, respectively. Loss-to-follow-up, reported in 40 (80%) studies, ranged from 0.3%–27%. Overall, SSA had the highest pooled 12-month mortality probability of 0.17 (95% CI 0.11–0.24) versus 0.11 (95% CI 0.10–0.13) for Asia, and 0.07 (95% CI 0.007–0.20) for the Americas. Of 14 (28%) studies reporting cause-specific mortality, tuberculosis (TB) (5%–44%), wasting (5%–53%), advanced HIV (20%–37%), and chronic diarrhea (10%–25%) were most common. Independent factors associated with early mortality in 30 (60%) studies included: low baseline CD4 cell count, male sex, advanced World Health Organization clinical stage, low body mass index, anemia, age greater than 40 years, and pre-ART quantitative HIV RNA. Conclusions Significant heterogeneity in outcomes and in methods of reporting outcomes exist among published studies evaluating mortality in the first year after ART initiation in LMIC. Early mortality rates are highest in SSA, and opportunistic illnesses such as TB and wasting syndrome are the most common reported causes of death.

    2016-01-01

    Purpose of review The present review will highlight some of the recent findings regarding the capacity of HIV-1 to replicate during antiretroviral therapy (ART). Recent findings Although ART is highly effective at inhibiting HIV replication, it is not curative. Several mechanisms contribute to HIV persistence during ART, including HIV latency, immune dysfunction, and perhaps persistent low-level spread of the virus to uninfected cells (replication). The success in curing HIV will depend on efficiently targeting these three aspects. The degree to which HIV replicates during ART remains controversial. Most studies have failed to find any evidence of HIV evolution in blood, even with samples collected over many years, although a recent very intensive study of three individuals suggested that the virus population does shift, at least during the first few months of therapy. Stronger but still not definitive evidence for replication comes from a series of studies in which standard regimens were intensified with an integration inhibitor, resulting in changes in episomal DNA (blood) and cell-associated RNA (tissue). Limited drug penetration within tissues and the presence of immune sanctuaries have been argued as potential mechanisms allowing HIV to spread during ART. Mathematical models suggest that HIV replication and evolution is possible even without the selection of fully drug-resistant variants. As persistent HIV replication could have clinical consequences and might limit the efficacy of curative interventions, determining if HIV replicates during ART and why, should remain a key focus of the HIV research community. Summary Residual viral replication likely persists in lymphoid tissues, at least in a subset of individuals. Abnormal levels of immune activation might contribute to sustain virus replication.

    Human immunodeficiency virus (HIV) infection is considered a chronic medical condition. Several new drugs are available, including fixed-dose combination tablets, that have greatly simplified combination antiretroviral therapy (ART) regimens to treat HIV, while increasing the life-expectancy of infected individuals. In the last decade, multiple well-regarded studies have established the benefits of using ART in high-risk, HIV-negative persons to prevent HIV acquisition. The primary care provider must not only understand commonly encountered issues pertaining to ART, such as toxicities and drug interactions, but also needs to be aware of using ART for HIV prevention.

    Acute kidney injury (AKI) and chronic kidney disease (CKD) are more common in the HIV-infected population than in the general population. AKI is associated with an increased risk of heart failure, cardiovascular disease, end-stage renal disease (ESRD), and mortality. Tenofovir is associated with severe AKI in a small percentage of patients and with subclinical abnormalities in many more. HIV-associated nephropathy is now a relatively rare form of CKD, because of the widespread use of potent antiretroviral therapy. The CKD spectrum in HIV-infected patients has become more frequently characterized by comorbid CKD, with an increased frequency of CKD related to diabetes or hypertension being observed. Kidney transplantation is a therapeutic option for HIV-infected patients with ESRD if their HIV infection is controlled, although rates of acute graft rejection and drug-drug interactions are high. This article summarizes a presentation by Christina M. Wyatt, MD, at the IAS-USA continuing education program held in Washington, DC, in June 2013. PMID:25101531

    This paper examines the effects of antiretroviral therapy (ART) on demand for HIV testing and of ART-induced testing on demand for risky sexual behavior. I provide a model of sexual behavior decision-making under uncertainty and estimate the structural parameters of the model using nationally representative survey data from Zambia on HIV testing decisions before and after the introduction of ART. The empirical results indicate that although the introduction of ART appears to have increased HIV testing rates by upwards of 50 percent, the ART allocation process may have limited the prevention benefit of ART-induced testing. Simulation results show that eliminating this prevention inefficiency while holding the supply of ART constant would increase the prevention impact of ART-induced testing more than four-fold. More generally, the analysis indicates that existing studies which examine "universal" testing or quasi-experimental testing programs understate the efficacy of standard voluntary counseling and testing programs.

    Among 35 million people living with the human immunodeficiency virus (HIV) in 2013, only 37% had access to antiretroviral therapy (ART). Despite global concerted efforts to provide the universal access to the ART treatment, the ART coverage varies among countries and regions. At present, there is a lack of systematic empirical analyses on factors that determine the ART coverage. Therefore, the current study aimed to identify the determinants of the ART coverage in 41 countries in Sub-Saharan Africa. It employed statistical analyses for this purpose. Four elements, namely, the HIV prevalence, the level of national income, the level of medical expenditure and the number of nurses, were hypothesised to determine the ART coverage. The findings revealed that among the four proposed determinants only the HIV prevalence had a statistically significant impact on the ART coverage. In other words, the HIV prevalence was the sole determinant of the ART coverage in Sub-Saharan Africa. PMID:26664812

    Under-reporting of ADR may be associated with poor knowledge, attitudes and practices to pharmacovigilance. This study evaluated knowledge, attitudes and practices of healthcare professionals about ADR monitoring and reporting following interventions. This longitudinal study included 36 healthcare professionals participating in ART program in a tertiary hospital. Interventions included group training on pharmacovigilance (PV) and provision of ADR reporting forms amongst others. Assessments were conducted at months 0 and 6 post-interventions using study-specific Likert-type instruments. Mean attitude scores above midpoint of 3.6 on 5-point scale were regarded as positive and below as negative. P<0.05 used to determine statistical significance. Mean age of participants was 36.6 (95%CI, 34.5–38.7) years; 61.1% males; 44.4% doctors, 13.9% pharmacists, 19.4% nurses, 8.3% laboratory scientists, 8.3% record officers and 5.6% welfare officers. None had received training on PV previously. Mean knowledge test score increased from 53.6% (95%CI, 44.6–63.6) at pre-intervention to 77.1% (95%CI, 72.8–81.4) at post-intervention with a mean change of 146.9% (95%CI, 60.5–233.3; p=0.000). Mean rated attitude scores increased from 3.6 (95%CI, 3.4–3.8) at pre-intervention to 4.2 (95%CI, 4.0–4.4) at post-intervention; the difference was statistically significant (p=0.000). 75.8% reported that ADR reporting forms were not readily available at pre-intervention compared to 18.2% at postintervention; 15.2% had reported ADR previously at pre-intervention compared to 69.7% at post-intervention; 12.1% reported providing information regarding ADRs and its management always at pre-intervention compared to 45.5% at post-intervention; these differences were statistically significant (p<0.05). Lack/inadequate knowledge, unavailability of reporting forms and negative attitudes were barriers identified; and addressing them resulted in significant improvement in this setting. Scaling up

    Aims Despite proven benefits of antiretroviral therapy (ART), many HIV-infected injection drug users (IDU) do not access treatment even in settings with free health care. We examined whether methadone maintenance therapy (MMT) increased initiation and adherence to ART among an IDU population with free health care. Design We prospectively examined a cohort of opioid-using antiretroviral-naïve HIV-infected IDU and investigated factors associated with initiation of antiretroviral therapy as well as subsequent adherence. Factors independently associated with time to first initiation of antiretroviral therapy were modelled using Cox proportional hazards regression. Findings Between May 1996 and April 2008, 231 antiretroviral-naïve HIV-infected opioid using IDU were enrolled, among whom 152 (65.8%) initiated ART, for an incidence density of 30.5 (95% confidence interval [CI]: 25.9–35.6) per 100 person-years. After adjustment for time-updated clinical characteristics and other potential confounders, use of MMT was independently associated with more rapid uptake of antiretroviral therapy (relative hazard = 1.62 [95% CI: 1.15–2.28]; p = 0.006). Those prescribed methadone also had higher rates of ART adherence after first antiretroviral initiation (odds ratio = 1.49 [95% CI: 1.07–2.08]; p = 0.019). Conclusion These results demonstrate that MMT contributes to more rapid initiation and subsequent adherence to ART among opioid-using HIV-infected IDU. Addressing international barriers to the use and availability of methadone may dramatically increase uptake of HIV treatment among this population. PMID:20331553

    Abstract The often cited need to achieve ≥95% (nearly perfect) adherence to antiretroviral therapy (ART) for successful virologic outcomes in HIV may present a barrier to initiation of therapy in the early stages of HIV. This meta-analysis synthesized 43 studies (27,905 participants) performed across >26 countries, to determine the relationship between cut-off point for optimal adherence to ART and virologic outcomes. Meta-analysis was performed using a random-effect model to calculate pooled odds ratios with corresponding 95% confidence intervals. The mean rate of patients reporting optimal adherence was 63.4%. Compared with suboptimal adherence, optimal adherence was associated with a lower risk of virologic failure (0.34; 95% CI: 0.26–0.44). There were no significant differences in the pooled odds ratios among different optimal adherence thresholds (≥98–100%, ≥95%, ≥80–90%). Study design (randomized controlled trial vs observational study) (regression coefficient 0.74, 95% CI: 0.04–1.43, P < 0.05) and study region (developing vs developed countries; regression coefficient 0.56, 95% CI: 0.01–1.12, P < 0.05) remained as independent predictors of between-study heterogeneity, with more patients with optimal adherence from developing countries or randomized controlled trials experiencing virologic failure. The threshold for optimal adherence to achieve better virologic outcomes appears to be wider than the commonly used cut-off point (≥95% adherence). The cut-off point for optimal adherence could be redefined to a slightly lower level to encourage the prescribing ART at an early stage of HIV infection. PMID:27082595

    CNS infection is a nearly constant facet of systemic CNS infection and is generally well controlled by suppressive systemic antiretroviral therapy (ART). However, there are instances when HIV can be detected in the cerebrospinal fluid (CSF) despite suppression of plasma viruses below the clinical limits of measurement. We review three types of CSF viral escape: asymptomatic, neuro-symptomatic, and secondary. The first, asymptomatic CSF escape, is seemingly benign and characterized by lack of discernable neurological deterioration or subsequent CNS disease progression. Neuro-symptomatic CSF escape is an uncommon, but important, entity characterized by new or progressive CNS disease that is critical to recognize clinically because of its management implications. Finally, secondary CSF escape, which may be even more uncommon, is defined by an increase of CSF HIV replication in association with a concomitant non-HIV infection, as a consequence of the local inflammatory response. Understanding these CSF escape settings not only is important for clinical diagnosis and management but also may provide insight into the CNS HIV reservoir. PMID:25860317

    The 2016 Conference on Retroviruses and Opportunistic Infections highlighted exciting advances in antiretroviral therapy, including important data on investigational antiretroviral drugs and clinical trials. Clinical trials demonstrated benefits from a long-acting injectable coformulation given as maintenance therapy, examined intravenous and subcutaneous administration of a monoclonal antibody directed at the CD4 binding site of HIV-1, and provided novel data on tenofovir alafenamide. Several studies focused on the role of HIV drug resistance, including the significance of minority variants, transmitted drug resistance, use of resistance testing, and drug class-related resistance. Novel data on the HIV care continuum in low- and middle-income settings concentrated on differentiated HIV care delivery models and outcomes. Data on progress toward reaching World Health Organization 90-90-90 targets as well as outcomes related to expedited initiation of HIV treatment and adherence strategies were presented. Results from a trial in Malawi showed reduced rates of mother-to-child transmission among HIV-infected women who initiated antiretroviral therapy prior to pregnancy, and several studies highlighted the effect of antiretroviral therapy in pediatric populations. A special session was dedicated to the findings of studies of Ebola virus disease and treatment during the outbreak in West Africa. PMID:27398863

    Objective To estimate the population-level causal effect of source of payment for HIV medication on treatment adherence using Marginal Structural Models. Methods Data were obtained from an observational cohort of 76 HIV-infected individuals with at least 24 weeks of antiretroviral therapy treatment from 2002 to 2007 in Kampala, Uganda. Adherence was the primary outcome and it was measured using the 30-day visual analogue scale. Marginal structural models (MSM) were used to estimate the effect of source of payment for HIV medication on adherence, adjusting for confounding by income, duration on antiretroviral therapy (ART), timing of visit, prior adherence, prior CD4+ T cell count and prior plasma HIV RNA. Traditional association models were also examined and the results compared. Results Free HIV treatment was associated with a 3.8% improvement in adherence in the marginal structural model, while the traditional statistical models showed a 3.1–3.3% improvement in adherence associated with free HIV treatment. Conclusion Removing a financial barrier to treatment with ART by providing free HIV treatment appears to significantly improve adherence to antiretroviral therapy. With sufficient information on confounders, MSMs can be used to make robust inferences about causal effects in epidemiologic research. PMID:24039704

    Combination therapy with three drug regimens for human immunodeficiency virus (HIV) infection significantly suppresses the viral replication. However, this therapeutic impact is restricted by adverse drug events and response in terms of short and long term efficacy. There are multiple factors involved in different responses to antiretrovirals (ARVs) such as age, body weight, disease status, diet and heredity. Pharmacogenomics deals with individual genetic make-up and its role in drug efficacy and toxicity. In depth genetic research has provided evidence to predict the risk of developing certain toxicities for which personalized screening and surveillance protocols may be developed to prevent side effects. Here we describe the use of pharmacogenomics for optimal use of HAART (highly active antiretroviral therapy). PMID:26831415

    HIV has now become a manageable chronic disease. However, the treatment outcomes may get hampered by suboptimal adherence to ART. Adherence optimization is a concrete reality in the wake of ‘universal access’ and it is imperative to learn lessons from various studies and programmes. This review examines current literature on ART scale up, treatment outcomes of the large scale programmes and the role of adherence therein. Social, behavioural, biological and programme related factors arise in the context of ART adherence optimization. While emphasis is laid on adherence, retention of patients under the care umbrella emerges as a major challenge. An in-depth understanding of patients’ health seeking behaviour and health care delivery system may be useful in improving adherence and retention of patients in care continuum and programme. A theoretical framework to address the barriers and facilitators has been articulated to identify problematic areas in order to intervene with specific strategies. Empirically tested objective adherence measurement tools and approaches to assess adherence in clinical/ programme settings are required. Strengthening of ART programmes would include appropriate policies for manpower and task sharing, integrating traditional health sector, innovations in counselling and community support. Implications for the use of theoretical model to guide research, clinical practice, community involvement and policy as part of a human rights approach to HIV disease is suggested. PMID:22310817

    Simpson, Anthony

    2010-12-01

    Increasing access to antiretroviral therapy (ART), especially in urban areas in Zambia, has transformed the landscape of the HIV epidemic to include hope. Drawing upon long-term ethnographic research, this article briefly describes the religious ideas of a cohort of former students of a Catholic mission boarding school for boys. The discussion outlines their understanding of masculinity and charts their responses, first to voluntary counselling and testing for HIV, and, more recently, to the 'miraculous' returns to health they have experienced or witnessed as a result of ART. The article examines the problems of self-disclosure among self-identified Catholics who are aware of their HIV-positive status and their reluctance to publically acknowledge that they are receiving ART. The research locates the source of this reluctance within existing associations of Christianity with 'civilisation' and 'respectability.' The article concludes that the Catholic Church in Zambia needs to do more to combat negative responses to people living with HIV, which cause both shame and loss of respect and militate against Zambians coming forward to access ART as well as against good antiretroviral adherence. One way in which this might be achieved is for the Catholic Church to be more open about priests and other members of the religious community who are receiving ART. PMID:25875888

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

    Background. We sought to quantify the survival benefits attributable to antiretroviral therapy (ART) in South Africa since 2004. Methods. We used the Cost-Effectiveness of Preventing AIDS Complications–International model (CEPAC) to simulate 8 cohorts of human immunodeficiency virus (HIV)–infected patients initiating ART each year during 2004–2011. Model inputs included cohort-specific mean CD4+ T-cell count at ART initiation (112–178 cells/µL), 24-week ART suppressive efficacy (78%), second-line ART availability (2.4% of ART recipients), and cohort-specific 36-month retention rate (55%–71%). CEPAC simulated survival twice for each cohort, once with and once without ART. The sum of the products of per capita survival differences and the total numbers of persons initiating ART for each cohort yielded the total survival benefits. Results. Lifetime per capita survival benefits ranged from 9.3 to 10.2 life-years across the 8 cohorts. Total estimated population lifetime survival benefit for all persons starting ART during 2004–2011 was 21.7 million life-years, of which 2.8 million life-years (12.7%) had been realized by December 2012. By 2030, benefits reached 17.9 million life-years under current policies, 21.7 million life-years with universal second-line ART, 23.3 million life-years with increased linkage to care of eligible untreated patients, and 28.0 million life-years with both linkage to care and universal second-line ART. Conclusions. We found dramatic past and potential future survival benefits attributable to ART, justifying international support of ART rollout in South Africa. PMID:24307741

    To better understand patient beliefs, which may influence adherence to HIV care and treatment, we examined three dimensions of beliefs among Ethiopian adults (n = 1177) initiating antiretroviral therapy (ART). Beliefs about benefits of ART/HIV clinical care were largely accurate, but few patients believed in the ability of ART to prevent sexual transmission and many thought Holy Water could cure HIV. Factors associated with lower odds of accurate beliefs included advanced HIV, lack of formal education, and Muslim religion (benefits of ART/clinical care); secondary or university education and more clinic visits (ART to prevent sexual transmission); and pregnancy and Orthodox Christian religion (Holy Water). Assessment of patient beliefs may help providers identify areas needing reinforcement. In this setting, counselors also need to stress the benefits of ART as prevention and that Holy Water should not be used to the exclusion of HIV care and ART. PMID:26346333

    Objective: Model trajectories of viral load measurements from time of starting combination antiretroviral therapy (cART), and use the model to predict whether patients will achieve suppressed viral load (≤200 copies/ml) within 6-months of starting cART. Design: Prospective cohort study including HIV-positive adults (UK Collaborative HIV Cohort Study). Methods: Eligible patients were antiretroviral naive and started cART after 1997. Random effects models were used to estimate viral load trends. Patients were randomly selected to form a validation dataset with those remaining used to fit the model. We evaluated predictions of suppression using indices of diagnostic test performance. Results: Of 9562 eligible patients 6435 were used to fit the model and 3127 for validation. Mean log10 viral load trajectories declined rapidly during the first 2 weeks post-cART, moderately between 2 weeks and 3 months, and more slowly thereafter. Higher pretreatment viral load predicted steeper declines, whereas older age, white ethnicity, and boosted protease inhibitor/non-nucleoside reverse transcriptase inhibitors based cART-regimen predicted a steeper decline from 3 months onwards. Specificity of predictions and the diagnostic odds ratio substantially improved when predictions were based on viral load measurements up to the 4-month visit compared with the 2 or 3-month visits. Diagnostic performance improved when suppression was defined by two consecutive suppressed viral loads compared with one. Conclusions: Viral load measurements can be used to predict if a patient will be suppressed by 6-month post-cART. Graphical presentations of this information could help clinicians decide the optimum time to switch treatment regimen during the first months of cART. PMID:27124894

    2011-01-01

    Recent empirical studies and analyses have heightened interest in the use of expanded antiretroviral therapy (ART) for prevention of HIV transmission. However, ART is expensive, approximately $600 per person per year, raising issues of the cost and cost-effectiveness of ambitious ART expansion. The goal of this review is to equip the reader with the conceptual tools and substantive background needed to understand and evaluate the policy and programmatic implications of cost-effectiveness assessments of ART for prevention. We provide this review in six sections. We start by introducing and explaining basic concepts of health economics as they relate to this issue, including resources, costs, health metrics (such as Disability-Adjusted Life Years), and different types of economic analysis. We then review research on the cost and cost-effectiveness of ART as treatment, and on the cost-effectiveness of traditional HIV prevention. We describe critical issues in the epidemic impact of ART, such as suppression of transmission and the role of the acute phase of infection. We then present a conceptual model for conducting and interpreting cost-effectiveness analyses of ART as prevention, and review the existing preliminary estimates in this area. We end with a discussion of future directions for programmatic demonstrations and evaluation. PMID:21999776

    Background An interim analysis of data from the HIV Prevention Trials Network (HPTN) 052 trial showed that antiretroviral therapy (ART) prevented more than 96% of genetically linked infections caused by human immunodeficiency virus type 1 (HIV-1) in serodiscordant couples. ART was then offered to all patients with HIV-1 infection (index participants). The study included more than 5 years of follow-up to assess the durability of such therapy for the prevention of HIV-1 transmission. Methods We randomly assigned 1763 index participants to receive either early or delayed ART. In the early-ART group, 886 participants started therapy at enrollment (CD4+ count, 350 to 550 cells per cubic millimeter). In the delayed-ART group, 877 participants started therapy after two consecutive CD4+ counts fell below 250 cells per cubic millimeter or if an illness indicative of the acquired immunodeficiency syndrome (i.e., an AIDS-defining illness) developed. The primary study end point was the diagnosis of genetically linked HIV-1 infection in the previously HIV-1-negative partner in an intention-to-treat analysis. Results Index participants were followed for 10,031 person-years; partners were followed for 8509 person-years. Among partners, 78 HIV-1 infections were observed during the trial (annual incidence, 0.9%; 95% confidence interval [CI], 0.7 to 1.1). Viral-linkage status was determined for 72 (92%) of the partner infections. Of these infections, 46 were linked (3 in the early-ART group and 43 in the delayed-ART group; incidence, 0.5%; 95% CI, 0.4 to 0.7) and 26 were unlinked (14 in the early-ART group and 12 in the delayed-ART group; incidence, 0.3%; 95% CI, 0.2 to 0.4). Early ART was associated with a 93% lower risk of linked partner infection than was delayed ART (hazard ratio, 0.07; 95% CI, 0.02 to 0.22). No linked infections were observed when HIV-1 infection was stably suppressed by ART in the index participant. Conclusions The early initiation of ART led to a sustained

    Despite the introduction of antiretroviral therapy (ART), human immunodeficiency virus-1 (HIV) continues to cause a major impact worldwide. HIV-induced lung disease continues to represent a significant source of morbidity and mortality, although the spectrum of pulmonary diseases has changed. HIV significantly affects the lung, causing acute and chronic cellular changes in the alveolar space. The impact of ART on lung immunology still needs to be fully elucidated. Similar to the periphery, ART affects HIV viral load and reconstitutes CD4(+) T cells in the lung. ART has been associated with significant decreases in bronchoalveolar lavage lymphocytes and increases in B-cell numbers and functionality, resulting in improved immune responses to vaccinations. There are substantial clinical implications of these ART-induced alterations, including the emergence of immune reconstitution inflammatory syndrome and the increased incidences of noninfectious lung diseases, such as lung cancer and chronic obstructive lung disease. There continues to be many unanswered questions regarding the effects of ART on lung health and, in particular, the immune system. Growing knowledge in this area will hopefully diminish the incidence of these noninfectious lung diseases and further improve the health of individuals living with HIV. PMID:26974295

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

    Background Cryptococcal meningitis accounts for 20 to 25% of acquired immunodeficiency syndrome–related deaths in Africa. Antiretroviral therapy (ART) is essential for survival; however, the question of when ART should be initiated after diagnosis of cryptococcal meningitis remains unanswered. Methods We assessed survival at 26 weeks among 177 human immunodeficiency virus–infected adults in Uganda and South Africa who had cryptococcal meningitis and had not previously received ART. We randomly assigned study participants to undergo either earlier ART initiation (1 to 2 weeks after diagnosis) or deferred ART initiation (5 weeks after diagnosis). Participants received amphotericin B (0.7 to 1.0 mg per kilogram of body weight per day) and fluconazole (800 mg per day) for 14 days, followed by consolidation therapy with fluconazole. Results The 26-week mortality with earlier ART initiation was significantly higher than with deferred ART initiation (45% [40 of 88 patients] vs. 30% [27 of 89 patients]; hazard ratio for death, 1.73; 95% confidence interval [CI], 1.06 to 2.82; P = 0.03). The excess deaths associated with earlier ART initiation occurred 2 to 5 weeks after diagnosis (P = 0.007 for the comparison between groups); mortality was similar in the two groups thereafter. Among patients with few white cells in their cerebrospinal fluid (<5 per cubic millimeter) at randomization, mortality was particularly elevated with earlier ART as compared with deferred ART (hazard ratio, 3.87; 95% CI, 1.41 to 10.58; P = 0.008). The incidence of recognized cryptococcal immune reconstitution inflammatory syndrome did not differ significantly between the earlier-ART group and the deferred-ART group (20% and 13%, respectively; P = 0.32). All other clinical, immunologic, virologic, and microbiologic outcomes, as well as adverse events, were similar between the groups. Conclusions Deferring ART for 5 weeks after the diagnosis of cryptococcal meningitis was associated with

    The convenience of accessing antiretroviral therapy (ART) is important for initial access to care and subsequent adherence to ART. We conducted a qualitative study of people living with HIV/AIDS (PLWHA) and ART healthcare providers in Ghana in 2005. The objective of this study was to explore the participants' perceived convenience of accessing ART by PLWHA in Ghana. The convenience of accessing ART was evaluated from the reported travel and waiting times to receive care, the availability, or otherwise, of special considerations, with respect to the waiting time to receive care, for those PLWHA who were in active employment in the formal sector, the frequency of clinic visits before and after initiating ART, and whether the PLWHA saw the same or different providers at each clinic visit (continuity of care). This qualitative study used in-depth interviews based on Yin's case-study research design to collect data from 20 PLWHA and 24 ART healthcare providers as study participants. • Reported travel time to receive ART services ranged from 2 to 12 h for 30% of the PLWHA. • Waiting time to receive care was from 4 to 9 h. • While known government workers, such as teachers, were attended to earlier in some of the centres, this was not a consistent practice in all the four ART centres studied. • The PLWHA corroborated the providers' description of the procedure for initiating and monitoring ART in Ghana. • PLWHA did not see the same provider every time, but they were assured that this did not compromise the continuity of their care. Our study suggests that convenience of accessing ART is important to both PLWHA and ART healthcare providers, but the participants alluded to other factors, including open provider-patient communication, which might explain the PLWHA's understanding of the constraints under which they were receiving care. The current nation-wide coverage of the ART programme in Ghana, however, calls for the replication of this study to identify

    We applied the Protégé methodology for building knowledge-based systems to the domain of antiretroviral therapy. We modeled the task of prescribing drug therapy for HIV, abstracting the essential characteristics of the problem solving. We mapped our model of the antiretroviral-therapy domain to the class of constraint-satisfaction problems, and reused the propose-and-revise problem-solving method, from the Protégé library of methods, to build an antiretroviral therapy advisor, ART Critic. Careful modeling and using Protégé allowed us to build a useful and extensible knowledge-based application rapidly. PMID:9929295

    Free antiretroviral therapy (ART) has been provided through the public health system in Tanzania since 2004. The success of national ART roll out programme is premised upon collaborative efforts of health systems, communities and policy environment. However, community perceptions of ART and its implications on sexual behaviours and HIV/AIDS prevention remain largely unknown. Drawing on focus group discussions with young people, this paper examines perception about ART and the potential impact of antiretroviral therapy on risk sexual behaviour in rural Tanzania. Participants included a purposively selected sample of males and females aged 14-24 years. Results show that young people were both optimistic and concerned regarding availability of ART. Positive attitudes toward ART were associated with public health significance of therapy in managing opportunistic infections and extending lives of HIV infected persons. However, the positive outcomes of therapy were considered to be short lived, unsustainable and potentially threatening to the sexual health and wellbeing of HIV negative members in the community. ART was considered to empower infected persons to intentionally spread HIV to uninfected individuals in the community through deliberate unprotected sexual activities. The study highlights the significance of reinforcing HIV prevention while underscoring the need to provide appropriate information and increasing access to ART in rural areas of Tanzania. In conclusion, creating a therapy friendly atmosphere through information delivery is crucial in promoting social acceptability of antiretroviral therapy among youths. Efforts to improve access to antiretroviral drugs should re-emphasize prevention counselling to minimize sexual transmission of HIV. PMID:19402581

    Background High BMI and blood pressure are leading chronic disease risk factors in South Africa. Longterm effects of HIV and ART on adiposity and blood pressure are poorly understood, and direct comparisons of risk factor trajectories in HIV- versus HIV+ populations are rare. Methods In 2003 and 2010, height, weight, and blood pressure were recorded in a study population (n = 505) in KwaZulu-Natal, South Africa (30% adult HIV prevalence). We modeled change in BMI and BP longitudinally in HIV- individuals (n = 315), seroconverters (n = 32), HIV+ patients not on ART (HIV+ART−; n = 52), HIV+ patients on ART for 0–<2 years as of 2010 (HIV+ART0–<2 yrs; n = 18), patients on ART for 2–5 years (HIV+ART2–5yrs; n = 44), and a subgroup with unknown HIV status (n = 44). Difference-in-differences were assessed in reference to the HIV- population. Results Between 2003 and 2010, BMI increased significantly in the HIV- group, by 0.874 (95% CI 0.339, 1.41; p = 0.001), to 30.4. BMI drop was significantly greater in HIV+ART0-<2yrs than in HIV+ART2–5yrs (p = 0.005). DID in BMI in HIV+ART0-<2yrs versus the reference was -5.21 (95% CI -7.53, -2.90; p = 0.001), and DID in HIV+ART2–5yrs versus reference was -1.35 (95% CI -2.89, 0.189; p = 0.086). DID in SBP in HIV+ART−vs HIV- DID was -7.55 mmHg (95% CI -13.2 to -1.90; p = 0.009). Conclusion Short-term ART (0–<2 years) was associated with larger weight loss than either no ART or long-term ART. Once on ART for 2+ years, individuals ‘caught up’ on weight gain with the HIV- population. Our results showcase the importance of health system readiness to address the burgeoning double burden of disease in South Africa. PMID:27552195

    A cross-sectional analysis was carried out to describe adverse reactions to antiretroviral therapy (ART) reported by HIV-infected patients initiating treatment at two public health AIDS referral centers in Belo Horizonte, Brazil, 2001-2003 and to verify their association with selected variables. Adverse reactions were obtained through interview at the first follow-up visit (first month) after the antiretroviral prescription. Socio-demographic and behavioral variables related to ART were obtained from baseline and follow-up interviews and clinical variables from medical charts. Patients with four or more reactions were compared to those with less than four. Odds ratio with 95% confidence interval were estimated using logistic regression model for both univariate and multivariate analyses. At least one adverse reaction was reported by 92.2% of the participants while 56.2% reported four or more different reactions. Antiretroviral regimens including indinavir/ritonavir, irregular use of antiretrovirals and switch in regimens were independently associated with four or more adverse reactions (OR=7.92, 5.73 and 2.03, respectively). The initial period of ARV treatment is crucial and patients' perception of adverse reactions should be carefully taken into account. Strategies for monitoring and management of adverse reactions including the choice of regimens and the prevention of irregular ART should be developed in AIDS/HIV referral centers in Brazil to promote better adherence to antiretroviral therapy.

    The development of antiretroviral drugs has significantly changed the perception of HIV/AIDS from a very fatal to a chronic and potentially manageable disease, and the availability and administration of antiretroviral therapy (ART) has significantly reduced mortality and morbidity associated with HIV and AIDS. There is a relationship between ART and quality of life of people living with HIV and AIDS, and several studies have reported a strong positive association between ART and improved quality of life in different domains among people living with HIV and AIDS in both developed and developing countries. However, a few studies have reported on the negative effects of ART, which directly or indirectly relate to the quality of life and longevity of HIV-infected persons. In this review, the effects and benefits of ART on people living with HIV and AIDS based on studies done in developed and developing countries is examined. PMID:22893751

    Purpose While Argentina has significantly improved access to HIV care and antiretroviral therapy (ART) for both the general population and prisoners, the prevalence of alcohol use disorders (AUDs) among HIV-infected prisoners and their relationship to accessing ART in Argentina is currently unknown. This study aims to characterize the substance abuse patterns of HIV-infected prisoners in Argentina and to assess the independent correlates of receipt of pre-incarceration ART. Design/methodology/approach An anonymous, cross-sectional survey of 100 HIV-infected federal prisoners was conducted in the Buenos Aires municipality from July–December 2010. AUDs were assessed using the AUDIT scale. Findings A majority (63 per cent) of participants met criteria for AUDs, 45 per cent of subjects were diagnosed with HIV in prison and one-quarter had initiated ART during the current incarceration. In addition, over one-third (35 per cent) of participants did not receive ART during the pre-incarceration period despite receiving it upon incarceration. This correlated significantly with the presence of having an AUD (AOR 0.20, 95 per cent CI 0.06–0.74, p = 0.016). Practical implications AUDs are prevalent among HIV-infected prisoners in Argentina and are significantly related to negative secondary HIV prevention and treatment outcomes. While Argentina has provided an exemplary model of HIV-related health care reform within its prisons, future efforts to provide screening and treatment for AUDs are needed to improve the health of the nation’s incarcerated population. Originality/value This paper is the first to describe pre-incarceration drug and alcohol use disorders and issues related to access to ART among prisoners in Argentina. PMID:24772187

    As part of a retrospective analysis of 616 individuals followed from incident HIV infection for up to 18 years as part of the San Diego Primary Infection Cohort, we found 16 individuals who started antiretroviral therapy (ART) within the first 4 months of infection and subsequently interrupted ART after being virologically suppressed for a median of 1.75 years. No individual maintained sustained virologic control after interruption of ART, even when treatment was started during the earliest stages of HIV infection. Median time to HIV-RNA rebound after ART interruption was 0.9 months (range: 0.2-6.4 months). PMID:26544575

    Timely initiation of antiretroviral therapy (ART) is particularly important for HIV-discordant couples because viral suppression greatly reduces the risk of transmission to the uninfected partner. To identify issues and concerns related to ART initiation among HIV-discordant couples, we recruited a subset of discordant couples participating in a longitudinal study in Nairobi to participate in in-depth interviews and focus group discussions about ART. Our results suggest that partners in HIV-discordant relationships discuss starting ART, yet most are not aware that ART can decrease the risk of HIV transmission. In addition, their concerns about ART initiation include side effects, sustaining an appropriate level of drug treatment, HIV/AIDS-related stigma, medical/biological issues, psychological barriers, misconceptions about the medications, the inconvenience of being on therapy, and lack of social support. Understanding and addressing these barriers to ART initiation among discordant couples is critical to advancing the HIV "treatment as prevention" agenda. PMID:22866934

    Little is available in scholarly literature about how HIV-positive prisoners, especially in low-income countries, access antiretroviral therapy (ART) medication. We interviewed 18 prisoners at a large prison in Namibia to identify barriers to medication adherence. The lead nurse researcher was a long-standing clinic employee at the prison, which afforded her access to the population. We identified six significant barriers to adherence, including (1) the desire for privacy and anonymity in a setting where HIV is strongly stigmatized; (2) the lack of simple supports for adherence, such as availability of clocks; (3) insufficient access to food to support the toll on the body of ingesting taxing ART medications; (4) commodification of ART medication; (5) the brutality and despair in the prison setting, generally leading to discouragement and a lack of motivation to strive for optimum health; and (6) the lack of understanding about HIV, how it is transmitted, and how it is best managed. Because most prisoners eventually transition back to communitysettings when their sentences are served, investments in prison health represent important investments in public health. PMID:24499371

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

    Background Using methadone maintenance therapy (MMT) clinics to deliver antiretroviral therapy (ART) is an effective strategy to promote treatment initiation and adherence for HIV-positive drug users. This paper describes the implementation barriers perceived by service providers for an intervention pilot designed to integrate ART services in MMT clinics. Methods The study was conducted in six MMT clinics in Sichuan province, China. Two service providers selected from each of the six clinics underwent training in administering ART. The trained providers delivered ART-related services in their clinics. A focus group was conducted among the service providers to assess their experiences and perceived challenges in delivering integrated services. Results Barriers at policy, institutional, provider, and client levels were identified. Policy level barriers included household registration restrictions and a lack of insurance coverage for testing expenses. Inefficient coordination between treatment sites and MMT clinics was an obstacle at the institutional level. Insufficient training and added workload were barriers at the provider level. Finally, conflict with daily dosing habits was identified as the primary reason that clients did not accept ART. Conclusion Although integrating ART into MMT clinics is beneficial, multilevel barriers to implementation need to be addressed. This study documents the need for treatment transferability and insurance coverage, protection of client confidentiality, proper provider training, coordination with treatment sites, and individualized ART service for MMT clients.

    Adherence to antiretroviral therapy is a powerful predictor of response to therapy. For optimal antiretroviral therapy response, individuals need to take more than 95% of their prescribed medication. The most widely used method for measuring adherence is self-report of the number of missed doses and this should be done at every clinic visit. There are several well-recognized predictors of poor adherence, such as illicit drug use, depression, limited knowledge or ambivalence about starting treatment. Adherence can be improved by addressing these issues or through other means such as pill boxes or electronic reminders. PMID:12752896

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

    Objectives: Guidelines for antiretroviral therapy (ART) initiation have evolved, but consistently note that adherence problems should be considered and addressed. Little is known regarding the reasons providers delay ART initiation in clinically eligible patients. Methods: In 2009, we surveyed a probability sample of HIV care providers in 582 outpatient facilities in the United States and Puerto Rico with an open-ended question about nonclinical reasons for delaying ART initiation in otherwise clinically eligible patients. Results: Very few providers (2%) reported never delaying ART. Reasons for delaying ART were concerns about patient adherence (68%), patient acceptance (60%), and structural barriers (33%). Provider and practice characteristics were associated with reasons for delaying ART. Conclusion: Reasons for delaying ART were consistent with clinical guidelines and were both patient level and structural. Providers may benefit from training and access to referrals for ancillary services to enhance their ability to monitor and address these issues with their patients. PMID:25394912

    We investigated whether drug-related behaviors predicted antiretroviral therapy (ART) discontinuation among a cohort of injection drug users (IDU) in a Canadian setting. Cox regression analyses were used to investigate the impact of drug use patterns on rates of ART discontinuation among a sample of HIV-positive IDU in Vancouver, Canada between May 1996 and April 2008. In total, 408 HIV-positive IDU initiated ART during the study period, among whom 257 (63.0%) discontinued ART at least once. Rates of ART discontinuation were not significantly elevated among those who reported ongoing injection of heroin, cocaine, or other illicit drugs in comparison to those who reported not injecting drugs. However, public drug use was significantly predictive of ART discontinuation. Our findings may contribute to a reconsideration of the role of active drug use in determining retention in ART programs among IDU. PMID:22249956

    Background With the scale-up of antiretroviral therapy (ART), monitoring programme performance is needed to maximize ART efficacy and limit HIV drug resistance (HIVDR). Methods We implemented a WHO HIVDR prospective survey protocol at three treatment centers between 2012 and 2013. Data were abstracted from patient records at ART start (T1) and after 12 months (T2). Genotyping was performed in the HIV pol region at the two time points. Results Of the 425 patients enrolled, at T2, 20 (4.7%) had died, 66 (15.5%) were lost to follow-up, 313 (73.6%) were still on first-line, 8 (1.9%) had switched to second-line, 17 (4.0%) had transferred out and 1 (0.2%) had stopped treatment. At T2, 272 out of 321 on first and second line (84.7%) suppressed below 1000 copies/ml and the HIV DR prevention rate was 70.1%, just within the WHO threshold of ≥70%. The proportion of participants with potential HIVDR was 20.9%, which is higher than the 18.8% based on pooled analyses from African studies. Of the 35 patients with mutations at T2, 80% had M184V/I, 65.7% Y181C, and 48.6% (54.8% excluding those not on Tenofovir) had K65R mutations. 22.9% had Thymidine Analogue Mutations (TAMs). Factors significantly associated with HIVDR prevention at T2 were: baseline viral load (VL) <100,000 copies/ml [Adjusted odds ratio (AOR) 3.13, 95% confidence interval (CI): 1.36–7.19] and facility. Independent baseline predictors for HIVDR mutations at T2 were: CD4 count <250 cells/μl (AOR 2.80, 95% CI: 1.08–7.29) and viral load ≥100,000 copies/ml (AOR 2.48, 95% CI: 1.00–6.14). Conclusion Strengthening defaulter tracing, intensified follow-up for patients with low CD4 counts and/or high VL at ART initiation together with early treatment initiation above 250 CD4 cells/ul and adequate patient counselling would improve ART efficacy and HIVDR prevention. The high rate of K65R and TAMs could compromise second line regimens including NRTIs. PMID:26700639

We aimed to compare the prevalence of glucose metabolism disorders among HIV-infected adults on long-term ART to ART-naïve adults and HIV-negative controls, hypothesizing that the odds of glucose metabolism disorders would be 2-fold greater even after adjusting for possible confounders. Methods In this cross-sectional study conducted between October 2012 and April 2013, consecutive adults (>18 years) attending an HIV clinic in Tanzania were enrolled in 3 groups: 153 HIV-negative controls, 151 HIV-infected, ART-naïve, and 150 HIV-infected on ART for ≥ 2 years. The primary outcome was the prevalence of glucose metabolism disorders as determined by oral glucose tolerance testing. We compared glucose metabolism disorder prevalence between each HIV group vs. the control group by Fisher’s exact test and used multivariable logistic regression to determine factors associated with glucose metabolism disorders. Results HIV-infected adults on ART had a higher prevalence of glucose metabolism disorders (49/150 (32.7%) vs.11/153 (7.2%), p<0.001) and frank diabetes mellitus (27/150 (18.0%) vs. 8/153 (5.2%), p = 0.001) than HIV-negative adults, which remained highly significant even after adjusting for age, gender, adiposity and socioeconomic status (OR = 5.72 (2.78–11.77), p<0.001). Glucose metabolism disorders were significantly associated with higher CD4+ T-cell counts. Awareness of diabetes mellitus was <25%. Conclusions HIV-infected adults on long-term ART had 5-fold greater odds of glucose metabolism disorders than HIV-negative controls but were rarely aware of their diagnosis. Intensive glucose metabolism disorder screening and education are needed in HIV clinics in sub-Saharan Africa. Further research should determine how glucose metabolism disorders might be related to immune

    Based on social indicators collected within the TEMPRANO-ANRS12136 trial, we assessed the social consequences of early antiretroviral therapy (ART) initiation in west Africa. We did not observe any significant differences in the levels or the time trends of various social indicators, including union status, HIV disclosure and HIV-related discrimination, between early and deferred ART initiation. Early ART does not carry detectable adverse social consequences that could impair its clinical and preventive benefits. PMID:27003034

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

    Long-acting nanoformulated antiretroviral therapy (nanoART) induces a range of innate immune migratory, phagocytic and secretory cell functions that perpetuate drug depots. While recycling endosomes serve as the macrophage subcellular depots, little is known of the dynamics of nanoART-cell interactions. To this end, we assessed temporal leukocyte responses, drug uptake and distribution following both intraperitoneal and intramuscular injection of nanoformulated atazanavir (nanoATV). Local inflammatory responses heralded drug distribution to peritoneal cell populations, regional lymph nodes, spleen and liver. This proceeded for three days in male Balb/c mice. NanoATV-induced changes in myeloid populations were assessed by fluorescence-activated cell sorting (FACS) with CD45, CD3, CD11b, F4/80, and GR-1 antibodies. The localization of nanoATV within leukocyte cell subsets was determined by confocal microscopy. Combined FACS and ultra-performance liquid chromatography tandem mass-spectrometry assays determined nanoATV carriages by cell-based vehicles. A robust granulocyte, but not peritoneal macrophage nanoATV response paralleled zymosan A treatment. ATV levels were highest at sites of injection in peritoneal or muscle macrophages, dependent on the injection site. The spleen and liver served as nanoATV tissue depots while drug levels in lymph nodes were higher than those recorded in plasma. Dual polymer and cell labeling demonstrated a nearly exclusive drug reservoir in macrophages within the liver and spleen. Overall, nanoART induces innate immune responses coincident with rapid tissue macrophage distribution. Taken together, these works provide avenues for therapeutic development designed towards chemical eradication of human immunodeficiency viral infection. PMID:26716700

    Background The optimal time to initiate antiretroviral therapy (ART) in human immunodeficiency virus (HIV)–associated tuberculous meningitis is unknown. Methods We conducted a randomized, double-blind, placebo-controlled trial of immediate versus deferred ART in patients with HIV-associated tuberculous meningitis to determine whether immediate ART reduced the risk of death. Antiretroviral drugs (zidovudine, lamivudine, and efavirenz) were started either at study entry or 2 months after randomization. All patients were treated with standard antituberculosis treatment, adjunctive dexamethasone, and prophylactic co-trimoxazole and were followed up for 12 months. We conducted intention-to-treat, per-protocol, and prespecified subgroup analyses. Results A total of 253 patients were randomized, 127 in the immediate ART group and 126 in the deferred ART group; 76 and 70 patients died within 9 months in the immediate and deferred ART groups, respectively. Immediate ART was not significantly associated with 9-month mortality (hazard ratio [HR], 1.12; 95% confidence interval [CI], .81–1.55; P = .50) or the time to new AIDS events or death (HR, 1.16; 95% CI, .87–1.55; P = .31). The percentage of patients with severe (grade 3 or 4) adverse events was high in both arms (90% in the immediate ART group and 89% in the deferred ART group; P = .84), but there were significantly more grade 4 adverse events in the immediate ART arm (102 in the immediate ART group vs 87 in the deferred ART group; P = .04). Conclusions Immediate ART initiation does not improve outcome in patients presenting with HIV-associated tuberculous meningitis. There were significantly more grade 4 adverse events in the immediate ART arm, supporting delayed initiation of ART in HIV-associated tuberculous meningitis.

    Art, dance, and music therapy are a significant part of complementary medicine in the twenty-first century. These creative arts therapies contribute to all areas of health care and are present in treatments for most psychologic and physiologic illnesses. Although the current body of solid research is small compared with that of more traditional medical specialties, the arts therapies are now validating their research through more controlled experimental and descriptive studies. The arts therapies also contribute significantly to the humanization and comfort of modern health care institutions by relieving stress, anxiety, and pain of patients and caregivers. Arts therapies will greatly expand their role in the health care practices of this country in the twenty-first century. PMID:15458755

  11. Has the time come to abandon efavirenz for first-line antiretroviral therapy?

    PubMed

    2014-07-01

    Efavirenz has been recommended as a preferred third agent together with two nucleos(t)ides for first-line combination antiretroviral therapy (ART) for >15 years. The availability of efavirenz in a fixed-dose combination makes it very attractive. However, because of (i) adverse events associated with efavirenz, (ii) a poorer overall efficacy of efavirenz compared with newer antiretrovirals, (iii) the ranking of efavirenz as FDA Pregnancy Category D and (iv) the relatively high prevalence of transmitted drug-resistance mutations, there is a need to reconsider the role of efavirenz in first-line ART. We review the available evidence that challenges efavirenz's current position in first-line HIV treatment guidelines. Apart from its animal teratogenic potential, and moderate neuropsychiatric adverse events associated with its use, efavirenz has recently been associated with an increased risk of suicidality when compared with other antiretroviral drugs. Most importantly, efavirenz has demonstrated overall inferior efficacy to various comparator drugs, which include rilpivirine, raltegravir and dolutegravir, in antiretroviral-naive patients. Furthermore, epidemiological data indicate that the prevalence of non-nucleoside reverse transcriptase inhibitor resistance has reached 5%-8% in various parts of the world, and minority transmitted non-nucleoside reverse transcriptase inhibitor resistance-associated mutations can have a negative impact on the outcome of first-line efavirenz-based ART. Based on considerations of efficacy, toxicity and resistance, it is time to reconsider the routine use of efavirenz in ART. This, of course, presupposes that other antiretrovirals will be available in place of efavirenz, and may not be applicable in certain developing country settings where this is not the case.

    No study has tested the effectiveness of individualized cognitive behavioral therapy (CBT) interventions to reduce persistent nausea, pain, anxiety, and fatigue in patients on continuous antiretroviral therapy (ART). Our objective was to determine if CBT could reduce nausea, pain, anxiety, and fatigue in patients with HIV on ART. Men ages 40 to 56 years on ART (n = 18) at a suburban HIV clinic were randomly assigned to a control group or the CBT intervention. Usual adherence education and side-effect management were provided to both groups. Symptoms, health perception, medication adherence, and side-effect-reducing medication use were measured at four time points over 3 months. Participants in the intervention group rated usual fatigue and worst fatigue at 60 days, and nausea duration at 90 days significantly lower than controls (p < .05). Brief CBT training may reduce fatigue and nausea in patients with HIV undergoing ART. PMID:26996984

    Antiretroviral therapy is recommended for all patients with HIV infection. The benefit of immediate antiretroviral therapy was confirmed by results from the START (Strategic Timing of Antiretroviral Treatment) trial, which showed a 57% reduction in risk for the composite end point of AIDS-related events, serious non-AIDS-related events, or death from any cause with immediate treatment in antiretroviral therapy-naive participants with CD4+ cell counts above 500/µL. Other changes in HIV care include the widespread adoption of integrase strand transfer inhibitor-based regimens. Considerations regarding when to initiate antiretroviral therapy, which initial regimens to use, and appropriate monitoring of individuals taking antiretroviral therapy are discussed.

    Despite the decrease in opportunistic infections associated with HIV in the highly active antiretroviral treatment (HAART) era, a significant number of patients still present with skin pathology, some of which can be attributed directly or indirectly to antiretroviral therapy. The non-nucleoside reverse transcriptase inhibitors exhibit a class effect with regard to skin adverse manifestations, and the spectrum of disease can vary from a mild morbilliform rash to Stevens-Johnson syndrome. Certain protease inhibitors are associated with rash, and indinavir causes retinoid-like manifestations such as paronychia, alopecia, ingrown toe-nails, and curling of straight hair. Abacavir, a nucleoside reverse transcriptase inhibitor, is notorious for causing a hypersensitivity reaction in select patients. The fusion inhibitor enfuvirtide causes injection-site reactions in the overwhelming majority of patients, although a new method of delivery has decreased the rate and severity of these reactions. A syndrome of lipoatrophy with or without lipohypertrophy, often termed lipodystrophy, has been described in patients receiving HAART. Potential management of lipoatrophy includes switching antiretrovirals and surgical treatment with facial fillers. Lastly, skin manifestations of the immune reconstitution inflammatory syndrome, including herpes zoster and warts, must be recognized and treated accordingly. In the evaluation of the individual HIV-infected patient receiving antiretroviral therapy who presents with a skin disorder, clinicians should consider the CD4 cell count as a marker of the degree of immunodeficiency, the specific antiretrovirals used, and the timing of the initiation of antiretroviral therapy in order to formulate a rational differential diagnosis. Management should be individualized based on the specific drug that is implicated and the severity of the reaction. PMID:17645377

    Background Antiretroviral therapy (ART) decreases mortality risk in HIV-infected tuberculosis patients, but the effect of the duration of anti-tuberculosis therapy and timing of anti-tuberculosis therapy initiation in relation to ART initiation on mortality, is unclear. Methods We conducted a retrospective observational multi-center cohort study among HIV-infected persons concomitantly treated with Rifamycin-based anti-tuberculosis therapy and ART in Latin America. The study population included persons for whom 6 months of anti-tuberculosis therapy is recommended. Results Of 253 patients who met inclusion criteria, median CD4+ lymphocyte count at ART initiation was 64 cells/mm3, 171 (68%) received >180 days of anti-tuberculosis therapy, 168 (66%) initiated anti-tuberculosis therapy before ART, and 43 (17%) died. In a multivariate Cox proportional hazards model that adjusted for CD4+ lymphocytes and HIV-1 RNA, tuberculosis diagnosed after ART initiation was associated with an increased risk of death compared to tuberculosis diagnosis before ART initiation (HR 2.40; 95% CI 1.15, 5.02; P = 0.02). In a separate model among patients surviving >6 months after tuberculosis diagnosis, after adjusting for CD4+ lymphocytes, HIV-1 RNA, and timing of ART initiation relative to tuberculosis diagnosis, receipt of >6 months of anti-tuberculosis therapy was associated with a decreased risk of death (HR 0.23; 95% CI 0.08, 0.66; P=0.007). Conclusions The increased risk of death among persons diagnosed with tuberculosis after ART initiation highlights the importance of screening for tuberculosis before ART initiation. The decreased risk of death among persons receiving > 6 months of anti-tuberculosis therapy suggests that current anti-tuberculosis treatment duration guidelines should be re-evaluated.

    Summary The generalizability of clinical trial findings (efficacy) to routine care (effectiveness) may be limited. The present study found similar first year virologic and CD4 outcomes among antiretroviral-naïve patients treated through routine care vs. those participating in clinical trials. Background The generalizability of clinical trial findings (efficacy) to routine care (effectiveness) may be limited due to study eligibility criteria and volunteer bias. While well chronicled in many conditions, the efficacy vs. effectiveness of antiretroviral therapy (ART) remains understudied. Methods A retrospective study of the UAB 1917 Clinic Cohort evaluated naïve patients starting ART between 1/1/00–12/31/06. Patients received ART through clinical trials or routine care. Multivariable logistic and linear regression models were fit to evaluate factors associated with virologic failure (VF=VL>50 copies/mL) and change from baseline CD4 count 6 and 12 months after ART initiation. Sensitivity analyses evaluated the impact of missing data on outcomes. Results Among 570 patients starting ART during the study period, 121 (21%) enrolled in clinical trials vs. 449 (79%) receiving ART via routine care. ART receipt through routine care was not associated with VF at either 6 (OR=1.00;95%CI=0.54–1.86) or 12 (OR=1.56;95%CI=0.80–3.05) months in primary analyses. No significant differences in CD4 count responses at 6 and 12 months were observed. Conclusions Though marked differences in efficacy vs. effectiveness have been observed in the therapeutic outcomes of other conditions, our analyses found no evidence of such divergence among our patients initiating antiretroviral therapy for HIV.

    Perceived contagiousness is a major dimension underlying HIV-related stigmatization. Antiretroviral therapy (ART) can diminish contagiousness by reducing viral load levels in HIV-infected individuals. To test the assumption that reductions in contagiousness can lead to a decrease in stigmatizing reactions, we conducted an experimental online study. A sample of 752 participants (50.9% female) read a short vignette depicting an HIV-positive individual with either a high or a low viral load and were either given or not given information about the association between viral load and contagiousness. Subsequently, participants were asked to rate their willingness to stigmatize this individual by responding to two measures of social and physical distance. Differences between the low and the high viral load information groups and the combined no-information groups (forming a quasi-control group) were analyzed using analysis of covariance (ANCOVA), controlling for gender and baseline perceptions of contagiousness. The covariates, perceived contagiousness at baseline and gender, were associated with social and physical distancing, but the viral load/information factor was only significant in physical distancing. Planned contrast analyses confirmed that physical distancing in the informed group was lower in the low viral load condition compared to the high viral load condition and to the control group. We thus found evidence for the significant role of perceived contagiousness in the HIV-related stigma and were able to experimentally demonstrate the potential of ART to reduce HIV-related stigmatization by lowering viral load and contagiousness, when these changes are accompanied by a decreased perception of contagiousness.

    The treatment of HIV disease has led to a new division of management costs by shifting most of the necessary resources from inpatient treatment to outpatient management. Among the initiatives aimed at rationalising the resources available, we compared efficacy, tolerability and pharmacoeconomic impact of different regimes of antiretroviral therapy (ART). The survey covered the first 50 patients, clinically stable and with good viro-immunological response, who switched in June 2012 from an ART based on the triple combination of tenofovir (TDF), emtricitabine (FTC) and a protease inhibitor boosted with ritonavir (PI/r) or a non-nucleoside reverse transcriptase inhibitor (NNRTI), to a treatment based on abacavir (ABC), lamivudine (3TC) and a PI/r or NNRTI. Of the 50 patients who operated the switch, 39 replaced a PI with nevirapine (NVP), for which the largest group of patients was treated with ABC + 3TC + NVP. On 31 May 2015, all patients completed the observation period of 96 weeks, with a mean observation period of 132 weeks and clinical-laboratory checks every four months. Laboratory analysis revealed an optimal maintenance of viral suppression and absolute and relative number of CD4 + lymphocytes and improving trend of creatinine, proteinuria, serum phosphate and bone alkaline phosphatase. There was a variable effect on lipids, with a drop in triglycerides associated with a modest increase in total cholesterol. Much of the HIV-positive population reporting to our hospitals (>50%) comprises individuals who have for years been in stable viraemic suppression, making a satisfactory immune recovery while in good overall clinical condition. This type of patient was the target of the present survey. At the end of 96 weeks of observation the new regimes were well tolerated and did not lead to viro-immunological or clinical deterioration. Pharmacoeconomic analysis showed better containment of the overall costs. No patient needed to be hospitalised during the observation

    Vaginal shedding of cytomegalovirus (CMV) DNA was determined longitudinally among 96 women coinfected with human immunodeficiency virus (HIV), herpes simplex virus 2, and CMV starting antiretroviral therapy (ART) during a placebo-controlled trial of HSV-2 suppression with acyclovir in Rakai, Uganda. Vaginal CMV was detected in 75 of 96 women (78.0%) and 379 of 1080 individual visits (35.1%). ART status, higher HIV RNA viral load before ART initiation, and younger age were significantly associated with increased frequency of CMV shedding (P < .01). Compared to pre-ART, CMV shedding peaked from month 2 to month 4 after ART initiation, suggesting possible immune reconstitution inflammatory syndrome. Further studies need to determine the clinical significance of asymptomatic CMV shedding. PMID:25743428

    2015-12-01

    To reduce the burden of the HIV/AIDS epidemic, international donors recently began providing free antiretroviral therapy (ART) in parts of Sub-Saharan Africa. ART dramatically prolongs life and reduces infectiousness for people with HIV. This paper shows that ART availability increases work time for HIV-negative people without caretaker obligations, who do not directly benefit from the medicine. A difference-in-difference design compares people living near and far from ART, before and after treatment becomes available. Next we explore the possible reasons for this pattern. Although we cannot pinpoint the mechanism, we find that ART availability substantially reduces subjective mortality risk and improves mental health. These results show an undocumented economic consequence of the HIV/AIDS epidemic and an important externality of medical innovation. They also provide the first evidence of a link between the disease environment and mental health. PMID:26516983

    Individuals living with HIV who receive treatment and optimal care live longer and healthier lives. The purpose of this study was to develop a theoretical model to understand the effects of social context factors (individual, interpersonal, and social capital) that influence antiretroviral therapy (ART) adherence among a sample of HIV-infected Black men who use illicit drugs (N = 160). Ecosocial theory and social epidemiology provided the theoretical framework for this study. Multiple regression techniques and path analysis were used to test the model for these subjects. Homelessness among the subjects significantly affected adherence to ART. Tolerability of ART was observed to have a greater indirect effect on ART adherence than a direct effect. A positive state of mind and current illicit drug use indirectly affected ART adherence; however, significance was not achieved. Implications for the use of this theoretical model to guide research, clinical practice, and policy as part of a human rights approach to HIV disease is articulated. PMID:21123085

    PubMed Central

    2014-01-01

    Abstract Antiretroviral therapy (ART) represents a significant milestone in the battle against AIDS. However, we continue learning about HIV and confronting challenges 30 years after its discovery. HIV has cleverly tricked both the host immune system and ART. First, the many HIV subtypes and recombinant forms have different susceptibilities to antiretroviral drugs, which may represent an issue in countries where ART is just being introduced. Second, even under the suppressive pressures of ART, HIV still increases inflammatory mediators, deregulates apoptosis and proliferation, and induces oxidative stress in the host. Third, the preference of HIV for CXCR4 as a co-receptor may also have noxious outcomes, including potential malignancies. Furthermore, HIV still replicates cryptically in anatomical reservoirs, including the lung. HIV impairs bronchoalveolar T-lymphocyte and macrophage immune responses, rendering the lung susceptible to comorbidities. In addition, HIV-infected individuals are significantly more susceptible to long-term HIV-associated complications. This review focuses on chronic obstructive pulmonary disease (COPD), pulmonary arterial hypertension, and lung cancer. Almost two decades after the advent of highly active ART, we now know that HIV-infected individuals on ART live as long as the uninfected population. Fortunately, its availability is rapidly increasing in low- and middle-income countries. Nevertheless, ART is not risk-free: the developed world is facing issues with antiretroviral drug toxicity, resistance, and drug–drug interactions, while developing countries are confronting issues with immune reconstitution inflammatory syndrome. Several aspects of the complexity of HIV persistence and challenges with ART are discussed, as well as suggestions for new avenues of research. PMID:24797368

    Objective: The impact of different antiretroviral agents on the risk of developing or surviving CNS disease remains unknown. The aim of this study was to investigate whether using antiretroviral regimens with higher CNS penetration effectiveness (CPE) scores was associated with reduced incidence of CNS disease and improved survival in the UK Collaborative HIV Cohort (CHIC) Study. Methods: Adults without previous CNS disease, who commenced combination antiretroviral therapy (cART) between 1996 and 2008, were included (n = 22,356). Initial and most recent cART CPE scores were calculated. CNS diseases were HIV encephalopathy (HIVe), progressive multifocal leukoencephalopathy (PML), cerebral toxoplasmosis (TOXO), and cryptococcal meningitis (CRYPTO). Incidence rates and overall survival were stratified by CPE score. A multivariable Poisson regression model was used to identify independent associations. Results: The median (interquartile range) CPE score for initial cART regimen increased from 7 (5–8) in 1996–1997 to 9 (8–10) in 2000–2001 and subsequently declined to 6 (7–8) in 2006–2008. Differences in gender, HIV acquisition risk group, and ethnicity existed between CPE score strata. A total of 251 subjects were diagnosed with a CNS disease (HIVe 80; TOXO 59; CRYPTO 56; PML 54). CNS diseases occurred more frequently in subjects prescribed regimens with CPE scores ≤4, and less frequently in those with scores ≥10; however, these differences were nonsignificant. Initial and most recent cART CPE scores ≤4 were independently associated with increased risk of death. Conclusion: Clinical status at time of commencing cART influences antiretroviral selection and CPE score. This information should be considered when utilizing CPE scores for retrospective analyses.

    The Initiation of Antiretroviral Therapy in Early Asymptomatic HIV Infection (START) study has reinforced the benefits of early initiation of antiretroviral therapy (ART). However, a notable secondary finding from that study was that immediate initiation of ART did not prevent cardiovascular disease (CVD) events (0.17 vs 0.20 events/1000 person-years, P = .65). This result appears to contradict a body of evidence, most notably from the Strategies for Management of Antiretroviral Therapy (SMART) study, which reported a 70% increased hazard of cardiovascular events for those deferring or interrupting treatment. Thus, an important unresolved question is whether the timing of ART impacts CVD risk. In this review, published data on relationships between timing of ART and CVD risk are reviewed. The data support a role for ART in mitigating CVD risk at lower CD4 counts, but data also suggests that, among those initiating therapy early, ART alone appears to suboptimally mitigate CVD risk. Additional interventions to address CVD risk among human immunodeficiency virus-infected populations are likely to be needed. PMID:26989755

    The use of combination antiretroviral therapy (cART) to prevent HIV mother-to-child transmission during pregnancy and delivery is generally considered safe. However, vigilant assessment of potential risks of these agents remains warranted. Epigenetic changes including DNA methylation are considered potential mechanisms linking the in utero environment with long-term health outcomes. Few studies have examined the epigenetic effects of prenatal exposure to pharmaceutical agents, including antiretroviral therapies, on children. In this study, we examined the methylation status of the LINE-1 and ALU-Yb8 repetitive elements as markers of global DNA methylation alteration in peripheral blood mononuclear cells obtained from newborns participating in the Pediatric HIV/AIDS Cohort Study SMARTT cohort of HIV-exposed, cART-exposed uninfected infants compared to a historical cohort of HIV-exposed, antiretroviral-unexposed infants from the Women and Infants Transmission Study Cohort. In linear regression models controlling for potential confounders, we found the adjusted mean difference of AluYb8 methylation of the cART-exposed compared to the -unexposed was −0.568 (95% CI: −1.023, −0.149) and for LINE-1 methylation was −1.359 (95% CI: −1.860, −0.857). Among those exposed to cART, subjects treated with atazanavir (ATV), compared to those on other treatments, had less AluYb8 methylation (−0.524, 95% CI: −0.025, −1.024). Overall, these results suggest a small but statistically significant reduction in the methylation of these repetitive elements in an HIV-exposed, cART-exposed cohort compared to an HIV-exposed, cART-unexposed historic cohort. The potential long-term implications of these differences are worthy of further examination. PMID:26067216

    Objectives To estimate mortality rates and prognostic factors in HIV-positive patients who started combination antiretroviral therapy between 1996–1999 and survived for more than ten years. Methods We used data from 18 European and North American HIV cohort studies contributing to the Antiretroviral Therapy Cohort Collaboration. We followed up patients from ten years after start of combination antiretroviral therapy. We estimated overall and cause-specific mortality rate ratios for age, sex, transmission through injection drug use, AIDS, CD4 count and HIV-1 RNA. Results During 50,593 person years 656/13,011 (5%) patients died. Older age, male sex, injecting drug use transmission, AIDS, and low CD4 count and detectable viral replication ten years after starting combination antiretroviral therapy were associated with higher subsequent mortality. CD4 count at ART start did not predict mortality in models adjusted for patient characteristics ten years after start of antiretroviral therapy. The most frequent causes of death (among 340 classified) were non-AIDS cancer, AIDS, cardiovascular, and liver-related disease. Older age was strongly associated with cardiovascular mortality, injecting drug use transmission with non-AIDS infection and liver-related mortality, and low CD4 and detectable viral replication ten years after starting antiretroviral therapy with AIDS mortality. Five-year mortality risk was <5% in 60% of all patients, and in 30% of those aged over 60 years. Conclusions Viral replication, lower CD4 count, prior AIDS, and transmission via injecting drug use continue to predict higher all-cause and AIDS-related mortality in patients treated with combination antiretroviral therapy for over a decade. Deaths from AIDS and non-AIDS infection are less frequent than deaths from other non-AIDS causes. PMID:27525413

    Objective To identify factors associated with antiretroviral therapy (ART) attrition among patients initiating therapy in 2005–2011 at two large, public-sector department-level hospitals, and to inform interventions to improve ART retention. Methods This retrospective cohort study used data from the iSanté electronic medical record (EMR) system. The study characterized ART attrition levels and explored the patient demographic, clinical, temporal, and service utilization factors associated with ART attrition, using time-to-event analysis methods. Results Among the 2 023 patients in the study, ART attrition on average was 17.0 per 100 person-years (95% confidence interval (CI): 15.8–18.3). In adjusted analyses, risk of ART attrition was up to 89% higher for patients living in distant communes compared to patients living in the same commune as the hospital (hazard ratio: 1.89, 95%CI: 1.54–2.33; P < 0.001). Hospital site, earlier year of ART start, spending less time enrolled in HIV care prior to ART initiation, receiving a non-standard ART regimen, lacking counseling prior to ART initiation, and having a higher body mass index were also associated with attrition risk. Conclusions The findings suggest quality improvement interventions at the two hospitals, including: enhanced retention support and transportation subsidies for patients accessing care from remote areas; counseling for all patients prior to ART initiation; timely outreach to patients who miss ART pick-ups; “bridging services” for patients transferring care to alternative facilities; routine screening for anticipated interruptions in future ART pick-ups; and medical case review for patients placed on non-standard ART regimens. The findings are also relevant for policymaking on decentralization of ART services in Haiti. PMID:25563149

    Introduction Adherence to antiretroviral therapy (ART) plays an important role in treatment outcomes. It is crucial to identify factors influencing adherence in order to optimize treatment responses. The aim of this study was to assess the rates of, and factors associated with, suboptimal adherence (SubAdh) in the first 24 months of ART in an Asian HIV cohort. Methods As part of a prospective resistance monitoring study, the TREAT Asia Studies to Evaluate Resistance Monitoring Study (TASER-M) collected patients’ adherence based on the World Health Organization-validated Adherence Visual Analogue Scale. SubAdh was defined in two ways: (i) <100% and (ii) <95%. Follow-up time started from ART initiation and was censored at 24 months, loss to follow-up, death, treatment switch, or treatment cessation for >14 days. Time was divided into four intervals: 0–6, 6–12, 12–18 and 18–24 months. Factors associated with SubAdh were analysed using generalized estimating equations. Results Out of 1316 patients, 32% ever reported <100% adherence and 17% ever reported <95%. Defining the outcome as SubAdh <100%, the rates of SubAdh for the four time intervals were 26%, 17%, 12% and 10%. Sites with an average of >2 assessments per patient per year had an odds ratio (OR)=0.7 (95% confidence interval (CI) (0.55 to 0.90), p=0.006), compared to sites with ≤2 assessments per patient per year. Compared to heterosexual exposure, SubAdh was higher in injecting drug users (IDUs) (OR=1.92, 95% CI (1.23 to 3.00), p=0.004) and lower in homosexual exposure (OR=0.52, 95% CI (0.38 to 0.71), p<0.001). Patients taking a nucleoside transcriptase inhibitor and protease inhibitor (NRTI+PI) combination were less likely to report adherence <100% (OR=0.36, 95% CI (0.20 to 0.67), p=0.001) compared to patients taking an NRTI and non-nucleoside transcriptase inhibitor (NRTI+NNRTI) combination. SubAdh decreased with increasing time on ART (all p<0.001). Similar associations were found with adherence

    Vietnam has a concentrated HIV epidemic, with the highest HIV prevalence being observed among people who inject drugs (PWID). Based on its experience scaling-up robust HIV interventions, Vietnam aims to further strengthen its response by harnessing the preventive benefits of antiretroviral therapy (ART). Mathematical modelling suggests that prioritizing key populations for earlier access to ART, combined with other prevention interventions, may have significant impact on the epidemic, cost-effectively reducing new HIV infections and deaths. Pilot studies are being conducted to assess feasibility and acceptability of expansion of HIV testing and counselling (HTC) and early ART among key populations and to demonstrate innovative service delivery models to address challenges in uptake of services across the care cascade. Earlier access of key populations to combination prevention interventions, combined with sustained political commitment and supportive environment for key populations, are essential for maximum impact of ART on the HIV epidemic in Vietnam.

    We present two HIV models that include the CTL immune response, antiretroviral therapy and a full logistic growth term for uninfected CD4+ T-cells. The difference between the two models lies in the inclusion or omission of a loss term in the free virus equation. We obtain critical conditions for the existence of one, two or three steady states, and analyze the stability of these steady states. Through numerical simulation we find substantial differences in the reproduction numbers and the behaviour at the infected steady state between the two models, for certain parameter sets. We explore the effect of varying the combination drug efficacy on model behaviour, and the possibility of reconstituting the CTL immune response through antiretroviral therapy. Furthermore, we employ Latin hypercube sampling to investigate the existence of multiple infected equilibria. PMID:22930342

    Objectives Despite the advent of antiretroviral therapy (ART), many children, particularly in the rural communities of Zimbabwe, remain vulnerable. The purpose of this study was to determine the factors and challenges facing children on antiretroviral therapy (ART) in Brunapeg area of Mangwe District, Zimbabwe. Methods A mixed-method approach involving interviewer-guided focus group discussions and piloted semi-structured questionnaires was utilized to collect data from different key population groups. The data obtained were analyzed through content coding procedures based on a set of predetermined themes of interest. Results A number of challenges emerged as barriers to the success of antiretroviral therapy for children. Primary care givers were less informed about HIV and AIDS issues for people having direct impact on the success of antiretroviral therapy in children whilst some were found to be taking the antiretroviral drugs meant for the children. It also emerged that some primary care givers were either too young or too old to care for the children while others had failed to disclose to the children why they frequently visited the Opportunistic Infections (OI) clinic. Most primary care givers were not the biological parents of the affected children. Other challenges included inadequate access to health services, inadequate food and nutrition and lack of access to clean water, good hygiene and sanitation. The lack of community support and stigma and discrimination affected their school attendance and hospital visits. All these factors contributed to non-adherence to antiretroviral drugs. Conclusions and Public Health Implications Children on ART in rural communities in Zimbabwe remain severely compromised and have unique problems that need multi-intervention strategies both at policy and programmatic levels. Effective mitigating measures must be fully established and implemented in rural communities of developing countries in the fight for universal

    Objective To estimate the impact of antiretroviral therapy (ART) on labor productivity and income using detailed employment data from two large tea plantations in western Kenya for HIV-infected tea pluckers who initiated ART. Design Longitudinal study using primary data on key employment outcomes for a group of HIV-infected workers receiving anti-retroviral therapy (ART) and workers in the general workforce. Methods We used nearest-neighbor matching methods to estimate the impacts of HIV/AIDS and ART among 237 HIV-positive pluckers on ART (index group) over a four year period (2 years pre- and post-ART) on four monthly employment outcomes—days plucking tea, total kilograms harvested, total days working, and total labor income. Outcomes for the index group were compared to those for a matched reference group from the general workforce. Results We observed a rapid deterioration in all four outcomes for HIV-infected subjects in the period before ART initiation and then a rapid improvement after treatment initiation. By 18–24 months after treatment initiation, the index group harvested 8% (males) and 19% (females) less tea than reference subjects. The index group earned 6% (males) and 9% (females) less income from labor than reference subjects. Women’s income would have dropped further if they had not been able to offset their decline in tea plucking by spending more time on non-plucking assignments. Conclusions HIV-infected workers experienced long-term income reductions before and after initiating ART. The implications of such long-term impacts in low-income countries have not been adequately addressed. PMID:23014516

    Abstract In 2009, the Department of Health and Human Services (DHHS) recommended initiating antiretroviral therapy (ART) for youth with HIV at higher CD4 counts (≤500 cells/mm3) than previously recommended (≤350 cells/mm3). Barriers experienced by providers regarding ART initiation in this population have not been assessed. From 12/2011–01/2012, we asked providers from the HIV Medicine Association listserv who prescribed ART to youth (ages 13–25 years) with behaviorally-acquired HIV to complete a web-based survey. We presented a clinical vignette to explore potential barriers for initiating ART. Overall, 274/290 (94%) respondents completed the survey. Most felt confident that evidence supported initiating ART at higher CD4 counts (94%), and that benefits outweighed the risks of long-term toxicity (98%) or developing resistance (88%). Most (96%) initiated ART in the patient vignette (age 19 years, CD4 count ∼400). Patient characteristics (e.g., unstable housing or drug use) were perceived as large barriers to ART initiation. Low response rate (13%) was a limitation. Respondents were knowledgeable about relevant DHHS guidelines, believed sufficient evidence supported ART initiation at higher CD4 counts, and would provide treatment to those with CD4 counts ≤500cells/mm3. Understanding and overcoming barriers to initiation of ART perceived by providers is important to ensure implementation of ART treatment guidelines. PMID:23937549

    Excess black-water flooding in central Thailand resulted in closure of several healthcare facilities in the Fall of 2011. Persons living with human immunodeficiency virus (HIV) infection were presumably at risk for interruption of antiretroviral therapy (ART), with consequent treatment failure. We conducted a retrospective cohort study of ART use among patients in care at a Thai HIV clinic that closed due to excess flood water. Among 217 patients on ART who had clinic appointments within the one-month interval before the floods through the one-month interval after the clinic re-opened, seven (3%) reported non-sustained ART access. Non-sustained ART access was independently associated with prior low self-reported ART adherence (P<0.001) and less than six-months duration on the ART regimen (P=0.03). Advanced ART receipt or procurement at other flood-free healthcare facilities were strategies associated with ART access. During a flood disaster, identification and close monitoring of at-risk patients, patient-staff communication, flood preparedness plans, "HIV care access for all" policies, and collaboration among patients, healthcare providers and the government are relevant issues within preparedness plans to optimize ART access.

    Despite China's free antiretroviral therapy (ART) program, there are high rates of treatment failure, large sociodemographic disparities in care outcomes and emerging medication resistance. Understanding patient medication adherence behaviors and challenges could inform adherence interventions to maximize the individual and prevention benefits of ART. This study assessed recent nonadherence and treatment interruption among 813 HIV-infected adult outpatients in Guangzhou, China. Participants completed a behavioral survey, underwent chart review, and were tested for syphilis, gonorrhea, and chlamydia. Factors associated with suboptimal adherence were identified using univariate and multivariate logistic regression. Among 721 HIV-infected adults receiving ART, 18.9% reported recent nonadherence (any missed ART in the past four weeks) and 6.8% reported treatment interruption (four or more weeks of missed ART in the past year). Lower education, living alone, alcohol use, and being on ART one to three years were associated with recent nonadherence. Male gender, lower education, and being on ART one to three years were associated with treatment interruption. ART medication adherence interventions are needed in China that include individualized, long-term adherence plans sensitive to patients' educational and economic situations. These interventions should also consider possible gender disparities in treatment outcomes and address the use of alcohol during ART. Successful ART medication adherence interventions in China can inform other international settings that face similar adherence challenges and disparities. PMID:24666239

    For healthcare professionals, the volume of literature available on herb-drug interactions often makes it difficult to separate experimental/potential interactions from those deemed clinically relevant. There is a need for concise and conclusive information to guide pharmacotherapy in HIV/AIDS. In this review, the bases for potential interaction of medicinal herbs with specific antiretroviral drugs are presented, and several botanicals are discussed for which clinically relevant interactions in humans are established. Such studies have provided, in most cases, sufficient ground to warrant the avoidance of concurrent administration of antiretroviral (ARVs) drugs with St John's wort (Hypericum perforatum), black pepper (Piper species) and grapefruit juice. Other botanicals that require caution in the use with antiretrovirals include African potato (Hypoxis hemerocallidea), ginkgo (Ginkgo biloba), ginseng (Panax species), garlic (Allium sativum), goldenseal (Hydrastis canadensis) and kava kava (Piper methysticum). The knowledge of clinically significant herb-drug interaction will be important in order to avoid herb-induced risk of sub-therapeutic exposure to ARVs (which can lead to viral resistance) or the precipitation of toxicity (which may lead to poor compliance and/or discontinuation of antiretroviral therapy).

    Background There is limited published data on the outcomes of infants starting antiretroviral therapy (ART) in routine care in Southern Africa. This study aimed to examine the baseline characteristics and outcomes of infants initiating ART. Methods We analysed prospectively collected cohort data from routine ART initiation in infants from 11 cohorts contributing to the International Epidemiologic Database to Evaluate AIDS in Southern Africa. We included ART naïve HIV-infected infants <12 months of age initiating ≥ three antiretroviral drugs between 2004 and 2012. Kaplan-Meier estimates were calculated for mortality, loss to follow-up (LTFU), transfer out and virological suppression. We used Cox Proportional Hazards models stratified by cohort to determine baseline characteristics associated with outcomes mortality and virological suppression. Results The median (interquartile range) age at ART initiation of 4945 infants was 5.9 months (3.7-8.7) with follow-up of 11.2 months (2.8-20.0). At ART initiation 77% had WHO clinical stage 3 or 4 disease and 87% were severely immunosuppressed. Three-year mortality probability was 16% and LTFU 29%. Severe immunosuppression, WHO stage 3 or 4, anaemia, being severely underweight and initiation of treatment before 2010 were associated with higher mortality. At 12 months after ART initiation 17% of infants were severely immunosuppressed and the probability of attaining virological suppression was 56%. Conclusion Most infants initiating ART in Southern Africa had severe disease with high probability of LTFU and mortality on ART. Although the majority of infants remaining in care showed immune recovery and virological suppression, these responses were suboptimal. PMID:26167620

    Objective In Brazil, universal provision of antiretroviral therapy (ART) has been guaranteed free of charge to eligible HIV-positive patients since December 1996. We sought to quantify the survival benefits of ART attributable to this programme. Methods We used a previously published microsimulation model of HIV disease and treatment (CEPAC-International) and data from Brazil to estimate life expectancy increase for HIV-positive patients initiating ART in Brazil. We divided the period of 1997 to 2014 into six eras reflecting increased drug regimen efficacy, regimen availability and era-specific mean CD4 count at ART initiation. Patients were simulated first without ART and then with ART. The 2014-censored and lifetime survival benefits attributable to ART in each era were calculated as the product of the number of patients initiating ART in a given era and the increase in life expectancy attributable to ART in that era. Results In total, we estimated that 598,741 individuals initiated ART. Projected life expectancy increased from 2.7, 3.3, 4.1, 4.9, 5.5 and 7.1 years without ART to 11.0, 17.5, 20.7, 23.0, 25.3, and 27.0 years with ART in Eras 1 through 6, respectively. Of the total projected lifetime survival benefit of 9.3 million life-years, 16% (or 1.5 million life-years) has been realized as of December 2014. Conclusions Provision of ART through a national programme has led to dramatic survival benefits in Brazil, the majority of which are still to be realized. Improvements in initial and subsequent ART regimens and higher CD4 counts at ART initiation have contributed to these increasing benefits. PMID:27029828

    2016-01-01

    Background Despite the success of antiretroviral therapy (ART), HIV-infected older African Americans experience higher mortality rates compared to their white counterparts. This disparity may be partly attributable to the differences in ART adherence by different racial and gender groups. The purpose of this study was to describe demographic, psychosocial, and HIV disease-related factors that influence ART adherence and to determine whether race and gender impact ART adherence among HIV-infected adults aged 50 years and older. Methods This descriptive study involved a secondary analysis of baseline data from 426 participants in “PRIME,” a telephone-based ART adherence and quality-of-life intervention trial. Logistic regression was used to examine the association between independent variables and ART adherence. Results Higher annual income and increased self-efficacy were associated with being ≥95% ART adherent. Race and gender were not associated with ART adherence. Conclusion These findings indicated that improvements in self-efficacy for taking ART may be an effective strategy to improve adherence regardless of race or gender. PMID:27071744

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

    Background Cohort studies have demonstrated greater risk of myocardial infarction (MI) associated with specific antiretroviral use, while meta-analyses of randomized controlled trials have not. These differences may be due to inherent biases in the observational study design or to the limited duration of randomized trials. We conducted a new-user, active-comparator cohort study emulating a randomized controlled trial comparing initiation of several antiretrovirals as part of combination antiretroviral therapy (cART) and MI. Methods We included North Carolina (NC) Medicaid beneficiaries infected with HIV between 2002 and 2008 who were previously untreated with cART. We compared hazard ratios (HRs) and 95% confidence intervals (CIs) of MI between abacavir and tenofovir recipients, and lopinavir-ritonavir or atazanavir recipients and non-nucleoside-reverse-transcriptase-inhibitor (NNRTI) recipients. We adjusted for confounding through inverse-probability-weighting methods. Results There were 3,481 NC Medicaid new cART recipients who contributed 6,399 person-years and experienced 38 MI events. Receiving abacavir compared with tenofovir as part of cART was associated with an increased rate of MI unadjusted (HR= 2.70 [95% CI= 1.24 - 5.91]; HR= 2.05 [0.72 - 5.86]). Point estimates also suggest a relationship between receipt of atazanavir or lopinavir-ritonavir compared with an NNRTI and MI, although, estimates were imprecise. Conclusions We found an increased rate of MI among patients initiating abacavir compared with tenofovir although the association was decreased after confounding adjustment. Without a very large prospective comparative clinical trial, a much larger observational study of patients initiating cART would be needed to better define this apparent association. PMID:24713880

    Few studies have compared hospitalisations before and after antiretroviral therapy (ART) initiation in the same patients. We analysed the cost of hospitalisations among 3,906 adult patients in two South African hospitals, 30% of whom initiated ART. Hospitalisations were 50% and 40% more frequent and 1.5 and 2.6 times more costly at a CD4 cell count <100 cells/mm3 when compared to 200–350 cells/mm3 in the pre-ART and ART period, respectively. Mean inpatient cost per patient year was USD 117 (95% confidence interval, CI, 85–158) for patients on ART and USD 72 (95% CI, 56–89) for pre-ART patients. Raising ART eligibility thresholds could avoid the high cost of hospitalisation before and immediately after ART initiation. PMID:23187948

    Consistent with an important role for adaptive immunity in modulating interactions between intestinal bacteria and host, dramatic alteration in the composition of gut microbes during chronic HIV infection was recently reported by ourselves and independently by four other research groups. Here we evaluate our results in the context of these other studies and delve into the effects of antiretroviral therapy (ART). Although gut microbiota of HIV-positive individuals on ART usually does not resemble that of HIV-negative individuals, the degree to which ART restores health-associated prevalence varies across bacterial taxa. Finally, we discuss potential drivers and health consequences of gut microbiota alterations. We propose that understanding the mechanism of HIV-associated gut microbiota changes will elucidate the role of adaptive immunity in shaping gut microbiota composition, and lay the foundation for therapeutics targeting the microbiota to attenuate HIV disease progression and reduce the risk of gut-linked disease in people with HIV.

    Introduction As access to prevention of mother-to-child transmission (PMTCT) efforts has increased, the total number of children being born with HIV has significantly decreased. However, those children who do become infected after PMTCT failure are at particular risk of HIV drug resistance, selected by exposure to maternal or paediatric antiretroviral drugs used before, during or after birth. As a consequence, the response to antiretroviral therapy (ART) in these children may be compromised, particularly when non-nucleoside reverse transcriptase inhibitors (NNRTIs) are used as part of the first-line regimen. We review evidence guiding choices of first- and second-line ART. Discussion Children generally respond relatively well to ART. Clinical trials show the superiority of protease inhibitor (PI)- over NNRTI-based treatment in young children, but observational reports of NNRTI-containing regimens are usually favourable as well. This is reassuring as national guidelines often still recommend the use of NNRTI-based treatment for PMTCT-unexposed young children, due to the higher costs of PIs. After failure of NNRTI-based, first-line treatment, the rate of acquired drug resistance is high, but HIV may well be suppressed by PIs in second-line ART. By contrast, there are currently no adequate alternatives in resource-limited settings (RLS) for children failing either first- or second-line, PI-containing regimens. Conclusions Affordable salvage treatment options for children in RLS are urgently needed. PMID:26639116

    ABSTRACT Limitations of antiretroviral therapy (ART) include poor patient adherence, drug toxicities, viral resistance, and failure to penetrate viral reservoirs. Recent developments in nanoformulated ART (nanoART) could overcome such limitations. To this end, we now report a novel effect of nanoART that facilitates drug depots within intracellular compartments at or adjacent to the sites of the viral replication cycle. Poloxamer 407-coated nanocrystals containing the protease inhibitor atazanavir (ATV) were prepared by high-pressure homogenization. These drug particles readily accumulated in human monocyte-derived macrophages (MDM). NanoATV concentrations were ∼1,000 times higher in cells than those that could be achieved by the native drug. ATV particles in late and recycling endosome compartments were seen following pulldown by immunoaffinity chromatography with Rab-specific antibodies conjugated to magnetic beads. Confocal microscopy provided cross validation by immunofluorescent staining of the compartments. Mathematical modeling validated drug-endosomal interactions. Measures of reverse transcriptase activity and HIV-1 p24 levels in culture media and cells showed that such endosomal drug concentrations enhanced antiviral responses up to 1,000-fold. We conclude that late and recycling endosomes can serve as depots for nanoATV. The colocalization of nanoATV at endosomal sites of viral assembly and its slow release sped antiretroviral activities. Long-acting nanoART can serve as a drug carrier in both cells and subcellular compartments and, as such, can facilitate viral clearance. IMPORTANCE The need for long-acting ART is significant and highlighted by limitations in drug access, toxicity, adherence, and reservoir penetrance. We propose that targeting nanoformulated drugs to infected tissues, cells, and subcellular sites of viral replication may improve clinical outcomes. Endosomes are sites for human immunodeficiency virus assembly, and increasing ART

    Purpose of review This review focuses on current and future strategies to modulate neuroinflammation while reducing residual viral burden in the central nervous system (CNS). This has been realized by targeted long acting antiretroviral nano- and adjunctive therapies being developed for HIV infected people. Our ultimate goal is to eliminate virus from its CNS reservoirs and, in so doing, reverse the cognitive and motor dysfunctions seen in HIV-associated neurocognitive disorders (HAND). Recent findings Herein, we highlight our laboratories development of adjunctive and nanomedicine therapies for HAND. An emphasis is placed on drug-drug interactions that target both the viral life cycle and secretory pro-inflammatory neurotoxic factors and signaling pathways. Summary Antiretroviral therapy (ART) has improved the quality and duration of life for people living with HIV-1. A significant long-term comorbid illness is HAND. Symptoms, while reduced in severity, are common. Disease occurs, in part, through continued low-level viral replication inducing secondary glial neuroinflammatory activities. Our recent works and those of others have seen disease attenuated in animal models through the use of adjunctive and long-acting reservoir targeted nanoformulated ART. The translation of these inventions from animals to humans is the focus of this review. PMID:25226025

    Expert guidelines for antiretroviral therapy (ART) now recommend ART as soon as possible in all HIV infected persons to reduce the risk of disease progression and prevent transmission. The goal of this observational study was to evaluate the impact of very early ART initiation and regimen type on time to viral suppression. We evaluated time to viral suppression among 86 persons with newly-diagnosed HIV infection who initiated ART within 30 days of diagnosis. A total of 36 (42%) had acute, 27 (31%) early, and 23 (27%) had established HIV infection. The median time from an offer of immediate ART to starting ART was 8 days. A total of 56/86 (65%) initiated an integrase inhibitor-based regimen and 30/86 (35%) a protease inhibitor-based regimen. The time to viral suppression was significantly shorter in those receiving an integrase inhibitor- versus a protease inhibitor-based regimen (p = 0.022). Twenty-two (26%) initiated ART at their HIV care intake visit and 79% of these participants achieved viral suppression at week 12, 82% at week 24 and 88% at week 48. ART initiated at the intake visit led to rapid and reliable viral suppression in acute, early and chronic HIV infection, in particular when integrase inhibitor-based regimens were used.

    A case-cohort study, within a multi-country trial of antiretroviral therapy (ART) efficacy (Prospective Evaluation of Antiretrovirals in Resource Limited Settings (PEARLS)), was conducted to determine if pre-ART serum selenium deficiency is independently associated with human immunodeficiency virus (HIV) disease progression after ART initiation. Cases were HIV-1 infected adults with either clinical failure (incident World Health Organization (WHO) stage 3, 4 or death by 96 weeks) or virologic failure by 24 months. Risk factors for serum selenium deficiency (<85 μg/L) pre-ART and its association with outcomes were examined. Median serum selenium concentration was 82.04 μg/L (Interquartile range (IQR): 57.28-99.89) and serum selenium deficiency was 53%, varying widely by country from 0% to 100%. In multivariable models, risk factors for serum selenium deficiency were country, previous tuberculosis, anemia, and elevated C-reactive protein. Serum selenium deficiency was not associated with either clinical failure or virologic failure in multivariable models. However, relative to people in the third quartile (74.86-95.10 μg/L) of serum selenium, we observed increased hazards (adjusted hazards ratio (HR): 3.50; 95% confidence intervals (CI): 1.30-9.42) of clinical failure but not virologic failure for people in the highest quartile. If future studies confirm this relationship of high serum selenium with increased clinical failure, a cautious approach to selenium supplementation might be needed, especially in HIV-infected populations with sufficient or unknown levels of selenium.

    Purpose Data on the prevalence of dyslipidaemia and associated risk factors in HIV-infected patients from sub-Saharan Africa is sparse. We performed a cross-sectional analysis in a cohort of HIV-infected South African adults. Methods We studied HIV-infected patients who were either antiretroviral therapy (ART)-naive or receiving non-nucleoside reverse transcriptase inhibitor (NNRTI)-based or protease inhibitor (PI)-based ART. Evaluation included fasting lipograms, oral glucose tolerance tests and clinical anthropometry. Dyslipidemia was defined using the NCEP ATPIII guidelines. Results The median age of the participants was 34 years (range 19–68 years) and 78% were women. The prevalence of dyslipidemia in 406 ART-naive and 551 participants on ART was 90.0% and 85%, respectively. Low HDL-cholesterol (HDLC) was the most common abnormality [290/406 (71%) ART-naïve and 237/551 (43%) ART- participants]. Participants on ART had higher triglycerides (TG), total cholesterol (TC), LDL-cholesterol (LDLC) and HDLC than the ART-naïve group. Severe dyslipidaemia, (LDLC> 4.9 mmol/L or TG >5.0 mmol/L) was present in <5% of participants. In multivariate analyses there were complex associations between age, gender, type and duration of ART and body composition and LDLC, HDLC and TG, which differed between ART-naïve and ART-participants. Conclusion Participants on ART had higher TG, TC, LDLC and HDLC than those who were ART-naïve but severe lipid abnormalities requiring evaluation and treatment were uncommon. PMID:26986065

    Long-term remission of HIV-1 disease can be readily achieved by combinations of antiretroviral agents. The suppression of plasma viral loads to less than the limit of quantification of the most sensitive commercially available assays (i.e., less than 50 copies/mL) and the coincident improvement in CD4 T cell counts is associated with resolution of established opportunistic infections and a decrease in the risk of new opportunistic infections. However, prolonged treatment with combination regimens can be difficult to sustain because of problems with adherence and toxic effects. All antiretroviral drugs can have both short-term and long-term adverse events. The risk of specific side effects varies from drug to drug, from drug class to drug class, and from patient to patient. A better understanding of the adverse effects of antiretroviral agents is of interest not only for HIV specialists as they try to optimize therapy, but also for other physicians who care for HIV-positive patients.

    The objective of this study was to examine the extent of unprotected sex among patients already established in HIV-medical care and their associated factors. Sexually active patients who were receiving antiretroviral therapy (ART) from five public hospitals in Trang province, Southern Thailand, were interviewed. Of 279 studied patients, 37.3% had unprotected sex in the prior 3 months and 27.2% did not disclose their serostatus to sexual partners. The median duration interquartile range (IQR) of using ART was 47 (27-60) months and 26.7% were non-adherent to ART (i.e., taking less than 95% of the prescribed doses). More than one-third had the perception that ART use would protect against HIV transmission even with unprotected sex. About 36.6% reported that they were unaware of their current CD4 counts and nearly one-third did not receive any safe sex counseling at each medical follow-up. After adjustment for potential confounders, non-adherence to ART and HIV-nondisclosure were strongly associated with an increase in the risk of unprotected sex with the adjusted odds ratio (aOR) of 5.03 (95% CI 2.68-9.44) and 3.89 (95% CI 1.57-9.61), respectively. In contrast, the risk for engaging in unprotected sex was less likely among patients having a negative-serostatus partner (aOR = 0.30; 95% CI 0.12-0.75), a longer duration of the use of ART (aOR = 0.98; 95%CI 0.97-0.99) and an unawareness of their current CD4 levels (aOR = 0.54; 95% CI 0.30-0.99). To maximize the benefits from ART, there should be a bigger emphasis on the "positive prevention" program and more efforts are needed to target the population at risk for unprotected sex. Strategies to encourage adherence to ART and for disclosure of serostatus are also required. PMID:26666292

    The concerted efforts of clinicians, scientists and caregivers of HIV-infected children have led to tremendous advances in our understanding of pediatric HIV/AIDS. Antiretroviral therapy (ART; formerly known as highly active antiretroviral therapy [HAART]) has significantly extended the longevity of HIV-infected children, but there are limitations to improvements in quality of life that may persist despite therapy. ART has remarkably reduced the incidence of neurologic deficits for the majority of infected children, but some patients do not experience these benefits and children living in poorer nations, who may not have access to antiretrovirals, are particularly at risk for developing neurologic deficits. This article reviews the neurologic symptoms of pediatric HIV infection that manifest as dopaminergic disruptions and explores potential future adjuvant therapies for HIV-related neurologic disorders in children.

    Background: Human immunodeficiency virus (HIV)-positive adolescents by virtue of their position are prone to dangerous behaviors including risk-taking for HIV transmission. Objective: To determine the awareness of HIV status and risk factors for HIV transmission among HIV-positive adolescents, and how these impact their behavior. Materials and Methods: A case study approach was used to study a random sample of 400 HIV-positive adolescent children attending an antiretroviral (ART) clinic in Kano, Kano State, Nigeria. Data were analyzed using Statistical Package for the Social Sciences (SPSS) 16.0 computer statistical software. Result: The mean age of the adolescents was 14.9 ± 3.15 years. The majority were females (54.8%) from a polygamous family (57.5%). About two-thirds or 251 (62.8%) patients knew their HIV status. The age of 14 years and above (z = 11.36, P = 0.0001) and having at least secondary school level of education (z = 2.78, P = 0.005) were significantly associated with awareness of HIV status on binary logistic regression. Up to 311 (77.8%) patients had good awareness of the risks of HIV transmission. Awareness of risk of HIV transmission was associated with awareness of HIV status (X2 = 166.2, P = 0.0001). There was a significant variation in the behaviors between those who were aware of their HIV status and those who were not. Paradoxically, the percentage differences in risk-taking were remarkably high in all the variables examined, and were all in the direction of the adolescents who had good knowledge of the risk factors for HIV transmission. Conclusion and Recommendation: Health ministries, development partners working in this field, and behavioral change communication experts should develop formidable strategies for addressing this menace. There is also a dire need for further research in this area. PMID:27051087

    In Uganda, the prevalence of non-adherence to antiretroviral therapy (ART) by HIV/AIDS patients remains high and sometimes this is blamed on patients' religious behavior. A descriptive design was used to examine the relationship between religiosity and ART adherence in a sample of 220 patients attending a HIV/AIDS clinic in a Ugandan public hospital. Participants who self-identified as Pentecostal and Muslim had the highest percentage of members with high religiosity scores and ART adherence. Among Muslim participants (34), 82% reported high religiosity scores and high levels of ART adherence. Of the fifty Pentecostals participants, 96% reported high religiosity scores and 80% reported high levels of ART adherence. Correlation analysis showed a significant relationship between ART adherence and religiosity (r = 0.618, P ≤ 0.01). Therefore, collaboration between religious leaders and HIV/AIDS healthcare providers should be encouraged as one of the strategies for enhancing ART adherence. PMID:21360222

    Adherence to clinical appointment schedules by patients on antiretroviral therapy (ART) is necessary for the prevention of medication interruptions, viral rebound, and the development of drug resistance. An observational study conducted in 2010, Enablers and Adherence to Antiretroviral Therapy in Cambodia, sought to identify factors that predict on-time clinical appointment attendance by patients on ART. Clinical data, including appointment attendance across five consecutive visits, were collected from hospital records on a random sample of ART patients at government referral hospitals (RHs) in Battambang Province, Cambodia. Interviews were conducted to obtain quantitative information from patients on their experiences of support services provided by local NGOs and RHs. This information was used to identify ART patient care and support system factors that could potentially enable patients to adhere to clinical appointment schedules. These factors included adherence counseling, support groups, home-based care (HBC) services, and support provided for transportation to ART appointments. Bivariate and multivariable logistic regression analysis was done to assess relationships between system variables and the ART appointment adherence outcome. Of the 289 study participants, 20.4% had missed at least one of the five appointments in the study period. The hospital source of ART services, participation in a hospital-based support group, receiving a loan from a microfinance institution, and the frequency of adherence counseling were found to be associated with ART appointment adherence. No significant associations were found between other support system factors such as HBC, transportation support, food/monetary support, and appointment adherence. PMID:25803006

    Regimen adherence, systemic toxicities, and limited drug penetrance to viral reservoirs are obstacles limiting the effectiveness of antiretroviral therapy (ART). Our laboratory’s development of the monocyte-macrophage-targeted long-acting nanoformulated ART (nanoART) carriage provides a novel opportunity to simplify drug-dosing regimens. Progress has nonetheless been slowed by cumbersome, but required, pharmacokinetic (PK), pharmacodynamics, and biodistribution testing. To this end, we developed a small magnetite ART (SMART) nanoparticle platform to assess antiretroviral drug tissue biodistribution and PK using magnetic resonance imaging (MRI) scans. Herein, we have taken this technique a significant step further by determining nanoART PK with folic acid (FA) decorated magnetite (ultrasmall superparamagnetic iron oxide [USPIO]) particles and by using SMART particles. FA nanoparticles enhanced the entry and particle retention to the reticuloendothelial system over nondecorated polymers after systemic administration into mice. These data were seen by MRI testing and validated by comparison with SMART particles and direct evaluation of tissue drug levels after nanoART. The development of alendronate (ALN)-coated magnetite thus serves as a rapid initial screen for the ability of targeting ligands to enhance nanoparticle-antiretroviral drug biodistribution, underscoring the value of decorated magnetite particles as a theranostic tool for improved drug delivery.

    Background Despite the increased prevalence of HIV in the rural female population of India, adherence to antiretroviral therapy continues to be low due to several barriers which discourage rural women. Objectives To assess the effectiveness of an intervention (Asha-Life) delivered by Accredited Social Health Activists to improve antiretroviral therapy adherence of rural women living with AIDS in India compared to that of a usual care group. Method A total of 68 rural women living with AIDS, aged 18–45 years, participated in a prospective, randomized pilot clinical trial and were assessed for several factors affecting adherence, such as sociodemographic characteristics, health history, CD4 cell count, enacted stigma, depressive symptomology, help getting antiretroviral therapy, and perceived therapy benefits. Results Findings at 6 months revealed that, while both groups improved their adherence to antiretroviral therapy, there was greater improvement in the Asha-Life group (p < .001), who reported a greater reduction in barriers to antiretroviral therapy than those in the usual care group. Discussion Antiretroviral therapy adherence showed significant increase in the Asha-Life cohort, in which basic education on HIV/AIDS, counseling on antiretroviral therapy, financial assistance, and better nutrition was provided. The Asha-Life intervention may have great potential in improving antiretroviral therapy adherence and decreasing barriers among rural women living with AIDS in India. PMID:22872107

    Background With the increase in scaling up of antiretroviral therapy (ART), knowledge of the need for adherence to ART is pivotal for successful treatment outcomes. Design and Methods A cross-sectional study was carried out between October and December 2013. We administered theory of planned behaviour (TPB) and adherence questionnaires to 358 women aged 18-49 years, from a rural and urban ART-clinics in southern Malawi. Hierarchical linear regression models were used to predict intentions to adhere to ART. Results Regression models show that attitude (β=0.47), subjective norm (β=0.31) and perceived behavioural control (β=0.12) explain 55% of the variance in intentions to adhere to ART. The relationship between both food insecurity and perceived side effects with intentions to adhere to ART is mediated by attitude, subjective norm, and perceived behavioural control. Household (r=0.20) and individual (r=0.21) food insecurity were positively and significantly correlated with perceived behavioural control. Household food insecurity had a negative correlation with perceived side effects (r=-0.11). Perceived side effects were positively correlated with attitude (r=0.25). There was no statistically significant relationship between intentions to adhere to ART in the future and one month self-report of past month adherence. These interactions suggest that attitude predicted adherence only when food insecurity is high or perception of side effects is strong. Conclusions This study shows that modification might be needed when using TPB constructs in resource constraint environments. Significance for public health The knowledge of the rates of adherence to antiretroviral therapy (ART) could be used to evaluate planning and project, which could lead to better outcomes predicted by treatment efficacy data. In addition, knowledge of adherence behaviour could help the development of interventions focusing on collaboration between healthcare providers and Malawian government to

    Introduction Some antiretroviral therapy naïve patients starting combination antiretroviral therapy (cART) experience a limited CD4 count rise despite virological suppression, or vice versa. We assessed the prevalence and determinants of discordant treatment responses in a Rwandan cohort. Methods A discordant immunological cART response was defined as an increase of <100 CD4 cells/mm3 at 12 months compared to baseline despite virological suppression (viral load [VL] <40 copies/mL). A discordant virological cART response was defined as detectable VL at 12 months with an increase in CD4 count ≥100 cells/mm3. The prevalence of, and independent predictors for these two types of discordant responses were analysed in two cohorts nested in a 12-month prospective study of cART-naïve HIV patients treated at nine rural health facilities in two regions in Rwanda. Results Among 382 patients with an undetectable VL at 12 months, 112 (29%) had a CD4 rise of <100 cells/mm3. Age ≥35 years and longer travel to the clinic were independent determinants of an immunological discordant response, but sex, baseline CD4 count, body mass index and WHO HIV clinical stage were not. Among 326 patients with a CD4 rise of ≥100 cells/mm3, 56 (17%) had a detectable viral load at 12 months. Male sex was associated with a virological discordant treatment response (P = 0.05), but age, baseline CD4 count, BMI, WHO HIV clinical stage, and travel time to the clinic were not. Conclusions Discordant treatment responses were common in cART-naïve HIV patients in Rwanda. Small CD4 increases could be misinterpreted as a (virological) treatment failure and lead to unnecessary treatment changes. PMID:27438000

    The hepatitis C virus (HCV) is an important contributor to morbidity and mortality in patients coinfected with human immunodeficiency virus (HIV). Coinfection results in increased HCV replication and more rapid rates of liver disease progression. The effect of HIV combination antiretroviral therapy (cART) on HCV replication has not been studied in depth. To address this issue, we enrolled a small cohort of HCV/HIV coinfected patients into a cART initiation trial, and used dynamic modeling combined with evaluation of immune responses and microarray profiles to determine how effective treatment of HIV affects HCV. Treatment with cART resulted in HCV flare and alanine aminotransferase (ALT) increase (2× or more increase from baseline) in a subset of treated patients. Subjects with evidence of hepatic injury (increased ALT) were more likely to have HCV-specific immune responses directed against HCV epitopes. Over time, HCV viral loads declined. Reproducible and biologically important gene expression changes occurred in patients who underwent successful cART, particularly with respect to downregulation of genes with known antiviral roles. Our findings suggest that the effective suppression of HIV by cART initiates a cascade of early and late events in treated patients with HCV. Early events involving downregulation of interferon-stimulated genes may lead to transiently increased viral replication and hepatic injury. At later time points, HCV viral load declines to levels comparable to those seen in the setting of HCV monoinfection. These findings support early antiretroviral therapy in those with HCV/HIV coinfection. PMID:25101888

    Abstract Taken as prescribed, that is, with high adherence, combination antiretroviral therapy (ART) has changed HIV infection and disease from being a sure predictor of death to a manageable chronic illness. Adherence, however, is difficult to achieve and maintain. The CAPRISA 058 study was conducted between 2007 and 2009 to test the efficacy of individualized motivational counselling to enhance ART adherence in South Africa. As part of the overall trial, a qualitative sub-study was conducted, including 30 individual interviews and four focus group discussions with patients in the first 9 months of ART initiation. Data were inductively analyzed, using thematic analysis, to identify themes central to ART adherence in this context. Four themes emerged that characterize the participants' experiences and high motivation to adhere to ART. Participants in this study were highly motivated to adhere, as they acknowledged that ART was ‘life-giving’, in the face of a large amount of morbidity and mortality. They were further supported by techniques of routine remembering, and highlighted the importance of good social support and access to supportive healthcare workers, to their continued success in negotiating their treatment. Participants in the current study told us that their adherence motivation is enhanced by free accessible care, approachable and supportive healthcare workers, broad social acceptance of ART, and past first-hand experiences with AIDS-related co-morbidity and mortality. Programs that include specific attention to these aspects of care will likely be successful in the long term. PMID:25692575

    Adherence to antiretroviral therapy (ART) is integral to the successful treatment of HIV infection. Research has indicated that HIV-infected Latinos may have difficulty adhering to ART. While studies have demonstrated strong relationships between numerous psychosocial factors and ART adherence, no research has examined if cultural factors are also involved in ART adherence among Latinos. Our study examined the relationship between acculturation to mainstream U.S. culture, bicultural self-efficacy, and ART adherence among HIV-infected Puerto Rican adults living in the United States. Participants with ≥ 95% adherence scored higher on U.S.- and Latino-involvement acculturation scales and on a measure of bicultural self-efficacy compared to those with suboptimal adherence. Among bicultural HIV-infected Puerto Ricans, both acculturation and self-efficacy to navigate between cultures were positively related to adherence. Understanding the role of an individual's sociocultural experience may help elucidate why HIV-infected Latinos have difficulties achieving optimal ART adherence and improve ART adherence interventions.

    Patient's adherence is crucial to get the best out of antiretroviral therapy (ART). This study explores in-depth the barriers to and facilitators of ART adherence among Nepalese patients and service providers prescribing ART. Face-to-face semi-structured interviews were conducted with 34 participants. Interviews were audio-taped, transcribed, and translated into English before being analyzed thematically. ART-prescribed patients described a range of barriers for failing to adhere to ART. Financial difficulties, access to healthcare services, frequent transport blockades, religious/ritual obstacles, stigma and discrimination, and side-effects were the most-frequently discussed barriers whereas trustworthy health workers, perceived health benefits, and family support were the most-reported facilitators. Understanding barriers and facilitators can help in the design of an appropriate and targeted intervention. Healthcare providers should address some of the practical and cultural issues around ART whilst policy-makers should develop appropriate social policy to promote adherence among ART-prescribed patients.

    HIV guidelines increasingly recommend antiretroviral therapy (ART) initiation at a higher CD4 levels. The extent to which these evolving standards are translated into routine clinical care has not been evaluated in Argentina. During October 2012, we conducted an online survey among Argentinean HIV clinicians to assess their attitudes and practices toward ART initiation and its potential use for HIV prevention. Of the 280 physicians included, 61% would prescribe ART at CD4 ≤ 500 cells/µL for asymptomatic patients. Although, only 11% would recommend ART irrespective of CD4 cell count, 72% would do it for serodiscordant couples, and 75% for sex workers. Most participants agreed that they would consider earlier initiation of ART if transmission risk exists, and that expansion of ART could help decrease HIV incidence. These results suggest that a large proportion of Argentinean HIV care providers are willing to adopt the recently updated Argentinean guidelines recommending earlier ART, especially when high HIV transmission risk exists.

    A study on knowledge about HIV/AIDS and antiretroviral therapy (ART) was conducted in the general population of a rural district in western Uganda. Three hundred seventy-two participants were selected by random cluster sampling and interviewed with an interview-administered questionnaire. Data were analyzed quantitatively with descriptive, univariate and linear multivariate statistical analysis with the knowledge score about ART as the dependent variable. The results indicate that the mean knowledge was 7.7 in a scale from 0 to 13. Predictor for better ART knowledge was a higher educational status of the participants. Older participants over 50 years were less ART knowledgeable. Only 19% of the participants have been tested for HIV. The conclusions are that the ART knowledge in this population is remarkably high which is reaffirming and important for achieving a high adherence to ART. Of concern is the low proportion of persons tested for HIV in this general population. Kabarole district seems to be receptive and capable for intensifying HIV testing which is a precondition for the ART roll-out. PMID:19085228

    In the era of combination antiretroviral therapy (ART), parsing out the effects of HIV vs ART on health outcomes is challenging. Nadir CD4 count, a marker of the extent of immunosuppression, has significant long-term impact on an array of disease states in HIV+ persons; however, in the dental literature, reporting of pre-ART exposure to immunosuppression has largely been ignored and this limits the validity of previous studies. In Workshop A1, we explain fully the importance of nadir CD4, pre-ART immunosuppression, and identify a need to include specific variables in future research. The questions posed herein are challenging, typically not neatly addressed by any one study and require integration of the latest evidence from the wider medical literature. We consider topics beyond the confines of the oral cavity and examine oral health in the complex context of ART era HIV immunopathophysiology. We depict how variability in geographic setting and time period (pre- and post-ART era) can impact oral conditions - influencing when HIV infection was detected (at what CD4 count), the type and timing of ART as well as social determinants such as strong stigma and limited access to care. We hope our Workshop will stir debate and energize a rigorous focus on relevant areas of future research in HIV/AIDS. PMID:27109282

    The perception in low-resource settings that investment of resources in people living with HIV (PLHIV) is wasted because AIDS is both an incurable and deadly disease is known as resource-based stigma. In this paper, we draw on in-depth interviews (IDI), focus group discussions (FGD), and key informant interviews (KII) with 77 HIV-positive microfinance participants and nongovernmental organization leaders to examine resource-based stigma in the context of increased access to antiretroviral therapy (ART) at an individual, household, and community level in Côte d'Ivoire. The purpose of this exploratory paper is to examine: (1) resource-based stigmatization in the era of ART and (2) the relationship among microfinance, a poverty-reduction intervention, and HIV stigmatization. The frequency with which resource-based stigma was discussed by respondents suggests that it is an important component of HIV-related stigma in this setting. It affected PLHIV's access to material as well as social resources, leading to economic discrimination and social devaluation. Participation in village savings and loans groups, however, mitigated resource-based HIV stigma, suggesting that in the era of increased access to antiretroviral therapy, economic programs should be considered as one possible HIV stigma-reduction intervention.

    Introduction Scientific research has demonstrated the clinical benefits of earlier initiation of antiretroviral treatment (ART), and that ART can markedly reduce HIV transmission to sexual partners. Ensuring universal access to ART for those who need it has long been a core principle of the HIV response, and extending the benefits of ART to key populations is critical to increasing the impact of ART and the overall effectiveness of the HIV response. However, this can only be achieved through coordinated efforts to address political, social, legal and economic barriers that key populations face in accessing HIV services. Discussion Recent analyses show that HIV prevalence levels among key populations are far higher than among the general population, and they experience a range of biological and behavioural factors, and social, legal and economic barriers that increase their vulnerability to HIV and have resulted in alarmingly low ART coverage. World Health Organization 2014 consolidated guidance on HIV among key populations offers the potential for increased access to ART by key populations, following the same principles as for the general adult population. However, it should not be assumed that key populations will achieve greater access to ART unless stigma, discrimination and punitive laws, policies and practices that limit access to ART and other HIV interventions in many countries are addressed. Conclusions Rights-based approaches and investments in critical enablers, such as supportive legal and policy environments, are essential to enable wider access to ART and other HIV interventions for key populations. The primary objective of ART should always be to treat the person living with HIV; prevention is an important, additional benefit. ART should be provided only with informed consent. The preventive benefits of treatment must not be used as a pretext for failure to provide other necessary HIV programming for key populations, including comprehensive harm

    In the context of HIV-infected patients with several past antiretroviral therapies and multiple failures, it is possible to be faced with viruses resistant to all drug classes. We report on two HIV-1 infected patients in which the historical genotype showed mutations against all the major drug classes and in which viral suppression has been obtained by non-conventional antiretroviral therapy regimens, including the combination of darunavir at high dosage (800 mg bid), dolutegravir (50 mg bid) and a third agent, i.e. enfuvirtide in the first case and etravirine in the second one.

    Objectives Adolescents living with HIV face substantial difficulties in accessing HIV care services and have worse treatment outcomes than other age groups. The objective of this review was to evaluate the effectiveness of service delivery interventions to improve adolescents' linkage from HIV diagnosis to antiretroviral therapy (ART) initiation, retention in HIV care and adherence to ART. Methods We systematically searched the Medline, SCOPUS and Web of Sciences databases and conference abstracts from the International AIDS Conference and International Conference on AIDS and STIs in Africa (ICASA). Studies published in English between 1st January 2001 and 9th June 2014 were included. Two authors independently evaluated reports for eligibility, extracted data and assessed methodological quality using the Cochrane risk of bias tool and Newcastle–Ottawa Scale. Results Eleven studies from nine countries were eligible for review. Three studies were randomised controlled trials. Interventions assessed included individual and group counselling and education; peer support; directly observed therapy; financial incentives; and interventions to improve the adolescent-friendliness of clinics. Most studies were of low to moderate methodological quality. Conclusions This review identified limited evidence on the effectiveness of service delivery interventions to support adolescents' linkage from HIV diagnosis to ART initiation, retention on ART and adherence to ART. Although recommendations are qualified because of the small numbers of studies and limited methodological quality, offering individual and group education and counselling, financial incentives, increasing clinic accessibility and provision of specific adolescent-tailored services appear promising interventions and warrant further investigation.

    Over half of patients with human immunodeficiency virus (HIV) experience diarrhea that contributes negatively to quality of life and adherence to antiretroviral therapy (ART). Opportunistic infectious agents that cause diarrhea in patients with HIV span the array of protozoa, fungi, viruses, and bacteria. With global use of ART, the incidence of diarrhea because of opportunistic infections has decreased; however, the incidence of noninfectious diarrhea has increased. The etiology of noninfectious diarrhea in patients with HIV is multifactorial and includes ART-associated diarrhea and gastrointestinal damage related to HIV infection (i.e., HIV enteropathy). A basic algorithm for the diagnosis of diarrhea in patients with HIV includes physical examination, a review of medical history, assessment of HIV viral load and CD4+ T cell count, stool microbiologic assessment, and endoscopic evaluation, if needed. For patients with negative diagnostic results, the diagnosis of noninfectious diarrhea may be considered. Pharmacologic options for the treatment of noninfectious diarrhea are primarily supportive; however, the use of many unapproved agents is based on unstudied and anecdotal information. In addition, these agents can be associated with treatment-limiting adverse events (AEs), such as drug-drug interactions with ART regimens, abuse liability, and additional gastrointestinal AEs. Currently, crofelemer, an antisecretory agent, is the only therapy approved in the USA for the symptomatic relief of noninfectious diarrhea in patients with HIV on ART. PMID:25772777

    The effects of antiretroviral therapy (ART) on the performance of HIV incidence assays have been well documented. To improve upon current assay approaches or focus the development of future assays, studies are needed to characterize the effects of ART on all candidate HIV incidence assays. In this study, we compared the performance of three antibody avidity-based HIV incidence assays, the Limiting Antigen (LAg), Bio-Rad Avidity, and HIV-1 Multiplex assays, using a well-defined cohort of recent HIV-1 seroconverters composed of ART-naive HIV-1-infected individuals and those who received ART early or delayed in the course of infection. Differences in the performance of all three avidity-based incidence assays were noted with study subjects who received ART. The LAg assay and Multiplex total antibody measurements (nMFI) exhibited similar kinetics in reactivity, as these assays tended to fluctuate with changes in viral load. In the early ART group, all seven subjects remained recent by both assays at time points >1 year postseroconversion, and assay values declined dramatically postdelayed ART initiation. In contrast, the two-well, antibody-dissociation avidity assays, Bio-Rad Avidity and Multiplex avidity index (AI) measurements, continued to mature in the early ART group, although blunted relative to the ART-naive group, and assay values remained stable after delayed ART initiation. In summary, although the HIV incidence assays evaluated in this study are all designed to measure antibody avidity, each assay is affected differently by ART-induced virus suppression, presumably because of the distinct assay formats and procedures for measuring avidity.

    Nevirapine (NVP) resistance occurs frequently in infants following NVP use in prevention of mother-to-child transmission (PMTCT) regimens. However, among previously NVP-unexposed infants treated with NVP-antiretroviral therapy (ART), the development and impact of NVP resistance have not been well characterized. In a prospective clinical trial providing early ART to HIV-infected infants <5 months of age in Kenya (OPH03 study), we followed NVP-unexposed infants who initiated NVP-ART for 12 months. Viral loads were assessed and resistance determined using a population-based genotypic resistance assay. Of 99 infants screened, 33 had no prior NVP exposure, 22 of whom were initiated on NVP-ART. Among 19 infants with follow-up, seven (37%) infants developed resistance: one at 3 months and six at 6 months after ART initiation. The cumulative probability of NVP resistance was 5.9% at 3 months and 43.5% at 6 months. Baseline HIV RNA levels (p=0.7) and other characteristics were not associated with developing resistance. Post-ART, higher virus levels at visits preceding the detection of resistance were significantly associated with increased detection of resistance (p=0.004). Virus levels after 6 and 12 months of ART were significantly higher in infants with resistance than those without (p=0.007, p=0.030, respectively). Among infants without previous NVP exposure, development of NVP resistance was frequent and was associated with virologic failure during the first year of ART. Earlier development of NVP resistance in infants than in adults initiating NVP-ART may be due to longer viremia following ART or inadequate NVP levels resulting from NVP lead-in dosing. The development of NVP resistance may, in part, explain the superiority of protease inhibitor-based ART in infants. PMID:25819584

    Objectives: We describe the frequency and types of drug therapy problems (DTPs), and interventions carried out to resolve them, among a cohort of HIV-infected patients on ART in Jos, Nigeria. Methods: A prospective pharmacists’ intervention study was conducted between January and August 2012 at the outpatient HIV clinic of the Jos University Teaching Hospital (JUTH). Pharmacists identified DTPs and made recommendations to resolve them. The main outcome measures were number of DTPs encountered, interventions proposed and acceptance rate of recommendations. Results: A total of 42,416 prescriptions were dispensed to 9339 patients during the eight months study. A total of 420 interventions (Intervention rate of 1 per 100 prescriptions) were made to resolve DTPs in 401 (4.3%) patients with a mean age of 41 (SD=10) years, and made up of 73% females. DTPs encountered were drug omission (n=89, 21.2%), unnecessary drug (n=55, 13.1%) and wrong drug indication (n=55, 13.1%). Recommendations offered included; Addition of another drug to the therapy (n=87, 20.7%), rectification of incomplete prescriptions (n=85, 20.2%), change of drug or dosage (n=67, 16.0%), and discontinuation of the offending drug (n=59, 14.0%). A total of 389 (93%) out of 420 of the recommendations were accepted. In all, 50.4% (212) of the problematic prescriptions were changed and dispensed, 22.2% (89) were clarified and dispensed, while wrong identities were corrected in 11.7% (49). However, 7.5% (30) prescriptions were dispensed as prescribed, 5.2% (21) were not dispensed, and 3% (12) were unresolved. Conclusion: Our findings suggest that pharmacists-initiated interventions can ameliorate DTPs in patients receiving ART given the high intervention acceptance rate recorded. The implication of this finding is that pharmacists with requisite training in HIV pharmacotherapy are an excellent resource in detecting and minimizing the effect of antiretroviral drug-related errors.

    Background: Study aim was to estimate the rate and identify predictors of discontinuation of first combination antiretroviral therapy (cART) in recent years. Methods: Patients who initiated first cART between January 2008 and October 2014 were included. Discontinuation was defined as stop of at least 1 drug of the regimen, regardless of the reason. All causes of discontinuation were evaluated and 3 main endpoints were considered: toxicity, intolerance, and simplification. Predictors of discontinuation were examined separately for all 3 endpoints. Kaplan–Meier analysis was used for the outcome discontinuation of ≥1 drug regardless of the reason. Cox regression analysis was used to identify factors associated with treatment discontinuation because of the 3 reasons considered. Results: A total of 4052 patients were included. Main reason for stopping at least 1 drug were simplification (29%), intolerance (21%), toxicity (19%), other causes (18%), failure (8%), planned discontinuation (4%), and nonadherence (2%). In a multivariable Cox model, predictors of discontinuation for simplification were heterosexual transmission (P = 0.007), being immigrant (P = 0.017), higher nadir lymphocyte T CD4+ cell (P = 0.011), and higher lymphocyte T CD8+ cell count (P = 0.025); for discontinuation due to intolerance: the use of statins (P = 0.029), higher blood glucose levels (P = 0.050). About toxicity: higher blood glucose levels (P = 0.010) and the use of zidovudine/lamivudine as backbone (P = 0.044). Conclusions: In the late cART era, the main reason for stopping the initial regimen is simplification. This scenario reflects the changes in recommendations aimed to enhance adherence and quality of life, and minimize drug toxicity. PMID:26871881

The primary outcome was medication adherence [percent of ART doses measured by the medication event monitoring system (MEMS) and pill counts] at the end of 24 weeks. The changes in the plasma viral loads from baseline and proportion of participants virological suppressed (<400 copies/mL) at the end of 24 weeks were assessed. Sixty-six percent (90/136) of eligible prisoners declined participation. Participants in the DOT arm (n = 20) had higher viral loads than participants in the SAT (n = 23) arm (p = 0.23). Participants, with complete data at 24 weeks, were analyzed as randomized. There were no significant differences in median ART adherence between the DOT (n = 16, 99% MEMS [IQR 93.9, 100], 97.1 % pill count [IQR 95.1, 99.3]) and SAT (n = 21, 98.3 % MEMS [IQR 96.0, 100], 98.5 % pill count [95.8, 100]) arms (p = 0.82 MEMS, p = 0.40 Pill Count) at 24 weeks. Participants in the DOT arm had a greater reduction in viral load of approximately -1 log 10 copies/mL [IQR -1.75, -0.05] compared to -0.05 [IQR -0.45, 0.51] in the SAT arm (p value = 0.02) at 24 weeks. The proportion of participants achieving virological suppression in the DOT vs SAT arms was not statistically different at 24 weeks (53 % vs 32 %, p = 0.21). These findings suggest that DOT ART programs in prison settings may not offer any additional benefit on adherence than SAT programs. PMID:25055766

    Despite the effectiveness of combination antiretroviral therapy in the treatment of people living with HIV/AIDS (PLWHA), nonadherence to medication has become a major threat to its effectiveness. This study aimed to estimate the prevalence of self-reported irregular use of antiretroviral therapy and the factors associated with such an irregularity in PLWHA. A cross-sectional study of PLWHA who attended two referral centers in the city of Recife, in Northeastern Brazil, between June 2007 and October 2009 was carried out. The study analyzed socioeconomic factors, social service support and personal habits associated with nonadherence to antiretroviral therapy, adjusted by multivariable logistic regression analysis. The prevalence of PLWHA who reported irregular use of combination antiretroviral therapy (cART) was 25.7%. In the final multivariate model, the irregular use of cART was associated with the following variables: being aged less than 40 years (OR = 1.66, 95%-CI: 1.29-2.13), current smokers (OR = 1.76, 95%-CI: 1.31-2.37) or former smokers (OR = 1.43, 95%-CI: 1.05-1.95), and crack cocaine users (OR = 2.79, 95%-CI: 1.24-6.32). Special measures should be directed towards each of the following groups: individuals aged less than 40 years, smokers, former smokers and crack cocaine users. Measures for giving up smoking and crack cocaine should be incorporated into HIV-control programs in order to promote greater adherence to antiretroviral drugs and thus improve the quality of life and prolong life expectancy.

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

    Guillain-Barré syndrome (GBS) has been reported in HIV-infected patients in association with the immune reconstitution syndrome whose symptoms can be mimicked by highly active antiretroviral therapy (HAART)-mediated mitochondrial toxicity. We report a case of a 17-year-old, HIV-infected patient on HAART with a normal CD4 count and undetectable viral load, presenting with acute lower extremity weakness associated with lactatemia. Electromyography/nerve conduction studies revealed absent sensory potentials and decreased compound muscle action potentials, consistent with a diagnosis of acute motor and sensory axonal neuropathy. Lactatemia resolved following cessation of HAART; however, neurological deficits minimally improved over several months in spite of immune modulatory therapy. This case highlights the potential association between HAART, mitochondrial toxicity and acute axonal neuropathies in HIV-infected patients, distinct from the immune reconstitution syndrome.

    Antiretroviral therapy (ART) has the potential to change processes of HIV stigmatisation. In this article, changing processes of stigmatisation among a group of people living with HIV (PLWH) on ART in Wakiso District, Uganda, are analysed using qualitative data from a study of PLWH's self-management of HIV on ART. There were 38 respondents (20 women, 18 men) who had been taking ART for at least 1 year. They were purposefully selected from government and non-government ART providers. Two in-depth interviews were held with each participant. Processes of reduced self-stigmatisation were clearly evident, caused by the recovery of their physical appearance and support from health workers. However most participants continued to conceal their status because they anticipated stigma; for example, they feared gossip, rejection and their status being used against them. Anticipated stigma was gendered: women expressed greater fear of enacted forms of stigma such as rejection by their partner; in contrast men's fears focused on gossip, loss of dignity and self-stigmatisation. The evidence indicates that ART has not reduced underlying structural drivers of stigmatisation, notably gender identities and inequalities, and that interventions are still required to mitigate and tackle stigmatisation, such as counselling, peer-led education and support groups that can help PLWH reconstruct alternative and more positive identities.

    Background It is unclear whether antiretroviral therapy (ART) should be initiated during acute HIV infection. Most recent data provides evidence of benefits of early ART. Methods We retrospectively compared the clinical and immunological course of individuals with acute HIV infection, who received ART within 3 months (group A) or not (group B) after diagnosis. Results Among the 84 individuals with acute HIV infection, 57 (68%) received ART within 3 months (A) whereas 27 (32%) did not receive ART within 3 months (B), respectively. Clinical progression to CDC stadium B or C within 5 years after the diagnosis of HIV was less common in (A) when compared to (B) (P = 0.002). After twelve months, both the mean increase in CD4+ T cell count and the mean decrease in viral load was more pronounced in (A), when compared to (B) (225 vs. 87 cells/μl; P = 0.002 and -4.19 vs. -1.14 log10 copies/mL; P<0.001). Twenty-four months after diagnosis the mean increase from baseline of CD4+ T cells was still higher in group A compared to group B (251 vs. 67 cells/μl, P = 0.004). Conclusions Initiation of ART during acute HIV infection is associated with a lower probability of clinical progression to more advanced CDC stages and significant immunological benefits.

    Introduction Substance abuse is a common problem among HIV-infected individuals. Importantly, addictions as well as moderate use of alcohol, smoking, or other illicit drugs have been identified as major reasons for non-adherence to antiretroviral therapy (ART) among HIV patients. The literature also suggests a decrease in the response to ART among HIV patients who use these substances, leading to failure to achieve optimal virological response and increased disease progression. Areas covered This review discusses the challenges with adherence to ART as well as observed drug interactions and known toxicities with major drugs of abuse, such as alcohol, smoking, methamphetamine, cocaine, marijuana, and opioids. The lack of adherence and drug interactions potentially lead to decreased efficacy of ART drugs and increased ART, and drugs of abuse-mediated toxicity. As CYP is the common pathway in metabolizing both ART and drugs of abuse, we discuss the possible involvement of CYP pathways in such drug interactions. Expert opinion We acknowledge that further studies focusing on common metabolic pathways involving CYP and advance research in this area would help to potentially develop novel/alternate interventions and drug dose/regimen adjustments to improve medication outcomes in HIV patients who consume drugs of abuse.

    Antiretroviral therapy (ART) is becoming increasingly more accessible within the health care system in Tanzania. However, the impact of the increased availability of ART on local conceptions about medicines, health and physical wellbeing has not been fully explored. In this article we examine how ART is constituted within local discourses about treatment and healing. Based on 21 focus group discussions with young people aged 14-24 years in a rural area (Kahe), we examine how local terms and descriptions of antiretroviral therapy relate to wider definitions about the body, health, illness and drug efficacy. Findings illustrate how local understandings of ART draw on a wider discourse about the therapeutic functions of medicines and clinical dimensions of HIV/AIDS. Therapeutic efficacy of antiretroviral medication appeared to overlap and sometimes contradict locally shared understandings of the clinical functions of medicines in the body. Implications of ART on bodily appearance and HIV signs may influence conceptions about sick role, perpetuate stigma and affect local strategies for HIV prevention. Structural inequities in access, limited information on therapeutic efficacy of ART and perceived difficulties with status disclosure appear to inform local conceptions and possible implications of ART. Policy and programme interventions to foster public understanding and acceptability of ART should emphasize treatment education about the benefits and limitations of therapy and increased access to ART in rural areas, and should integrate voluntary status disclosure and HIV prevention.

    Objective: This study compared 12-month CD4+ and viral load outcomes in HIV-infected children and adolescents with virological failure, managed with four treatment switch strategies. Design: This observational study included perinatally HIV-infected (PHIV) children in the Pediatric HIV/AIDS Cohort Study (PHACS) and Pediatric AIDS Clinical Trials (PACTG) Protocol 219C. Methods: Treatment strategies among children with virologic failure were compared: continue failing combination antiretroviral therapy (cART); switch to new cART; switch to drug-sparing regimen; and discontinue all ART. Mean changes in CD4+% and viral load from baseline (time of virologic failure) to 12 months follow-up in each group were evaluated using weighted linear regression models. Results: Virologic failure occurred in 939 out of 2373 (40%) children. At 12 months, children switching to new cART (16%) had a nonsignificant increase in CD4+% from baseline, 0.59 percentage points [95% confidence interval (95% CI) −1.01 to 2.19], not different than those who continued failing cART (71%) (−0.64 percentage points, P = 0.15) or switched to a drug-sparing regimen (5%) (1.40 percentage points, P = 0.64). Children discontinuing all ART (7%) experienced significant CD4+% decline −3.18 percentage points (95% CI −5.25 to −1.11) compared with those initiating new cART (P = 0.04). All treatment strategies except discontinuing ART yielded significant mean decreases in log10VL by 12 months, the new cART group having the largest drop (−1.15 log10VL). Conclusion: In PHIV children with virologic failure, switching to new cART was associated with the best virological response, while stopping all ART resulted in the worst immunologic and virologic outcomes and should be avoided. Drug-sparing regimens and continuing failing regimens may be considered with careful monitoring. PMID:26182197

    The objective of this study was to describe the pregnancy intentions of pregnant HIV-infected Malawian women on antiretroviral therapy (ART) for at least 6 months prior to the current pregnancy, and to assess whether time on ART was associated with pregnancy intention. We conducted a cross-sectional analysis of HIV-infected Malawian women receiving antenatal care at a government hospital with a survey assessing ART history, reproductive history, and family planning use at conception. We used Pearson's chi-square tests and Fisher's exact tests to compare these parameters between women on ART greater than 24 months with those on ART less than 24 months. Modified Poisson regression was performed to assess the association between time on ART and pregnancy intention. Most women (75%) reported that their current pregnancy was unintended, defined as either Mistimed (21%) or Unwanted (79%). Women on ART for longer than 2 years were more likely to report an unintended pregnancy (79% versus 65%, p = .03), though there was no significant association between time on ART and pregnancy intention in multivariate analysis. Most women (79%) were using contraception at the time of conception, with condoms being most popular (91%), followed by injectables (9%) and the implant (9%). HIV-infected women on ART continue to experience high rates of unintended pregnancy in the Option B+ era. As Option B+ continues to be implemented in Malawi and increasing numbers of HIV-infected women initiate lifelong ART, ensuring that the most effective forms of contraception are accessible is necessary to decrease unintended pregnancy.

    Objective The eradication of HIV necessitates elimination of the HIV latent reservoir. Identifying host determinants governing latency and reservoir size in the setting of antiretroviral therapy (ART) is an important step in developing strategies to cure HIV infection. We sought to determine the impact of cell-intrinsic immunity on the HIV latent reservoir. Design We investigated the relevance of a comprehensive panel of established anti-HIV-1 host restriction factors to multiple established virologic and immunologic measures of viral persistence in HIV-1-infected, ART-suppressed individuals. Methods We measured the mRNA expression of 42 anti-HIV-1 host restriction factors, levels of cell-associated HIV-1 RNA, levels of total pol and 2-LTR circle HIV-1 DNA, and immunophenotypes of CD4+ T cells in 72 HIV-1-infected subjects on suppressive ART (23 subjects initiated ART <1 year post-infection, and 49 subjects initiated ART >1 year post-infection). Correlations were analyzed using non-parametric tests. Results The enhanced expression of a few select host restriction factors, p21, schlafen 11, and PAF1, was strongly associated with reduced CD4+ T cell-associated HIV RNA during ART (p<0.001). In addition, our data suggested that ART perturbs the regulatory relationship between CD4+ T cell activation and restriction factor expression. Lastly, cell-intrinsic immune responses were significantly enhanced in subjects who initiated ART during early versus chronic infection, and may contribute to the reduced reservoir size observed in these individuals. Conclusions Intrinsic immune responses modulate HIV persistence during suppressive ART, and may be manipulated to enhance the efficacy of ART and promote viral eradication through reversal of latency in vivo.

    Considering that most patients who experience virological failure (VF) on lopinavir-based antiretroviral therapy (ART) fail due to poor adherence rather than resistance, an objective adherence measure could limit costs by rationalising the use of genotype antiretroviral resistance testing (GART) in countries with access to third-line ART. A cross-sectional study was conducted in a resource-limited setting at two large clinics in Kwazulu-Natal, South Africa, in patients experiencing VF (HIV-RNA > 1000 copies/mL) on lopinavir-based ART who had undergone GART. Associations between major protease inhibitor (PI) resistance mutations and random plasma lopinavir concentrations were explored. A total of 134 patients, including 31 children, were included in the analysis. The prevalence of patients with major PI resistance mutations was 20.9% (n = 28). A random lopinavir concentration above the recommended minimum trough of 1 µg/mL [adjusted odds ratio (aOR) = 5.81, 95% confidence interval (CI) 2.04-16.50; P = 0.001] and male sex (aOR = 3.19, 95% CI 1.22-8.33; P = 0.018) were predictive of the presence of at least one major PI resistance mutation. Random lopinavir concentrations of <1 µg/mL had a negative predictive value of 91% for major PI resistance mutations. Random lopinavir concentrations are strongly associated with the presence of major PI resistance mutations. Access to costly GART in patients experiencing VF on second-line ART could be restricted to patients with lopinavir concentrations above the recommended minimum trough of 1 µg/mL or, in areas where GART is unavailable, could be used as a criterion to empirically switch to third-line ART.

    Background As antiretroviral therapy (ART) for HIV becomes increasingly available in low and middle income countries (LMICs), understanding reasons for lack of adherence is critical to stemming the tide of infections and improving health. Understanding the effect of psychosocial experiences and mental health symptomatology on ART adherence can help maximize the benefit of expanded ART programs by indicating types of services, which could be offered in combination with HIV care. Methodology The Coping with HIV/AIDS in Tanzania (CHAT) study is a longitudinal cohort study in the Kilimanjaro Region that included randomly selected HIV-infected (HIV+) participants from two local hospital-based HIV clinics and four free-standing voluntary HIV counselling and testing sites. Baseline data were collected in 2008 and 2009; this paper used data from 36 month follow-up interviews (N = 468). Regression analyses were used to predict factors associated with incomplete self-reported adherence to ART. Results Incomplete ART adherence was significantly more likely to be reported amongst participants who experienced a greater number of childhood traumatic events: sexual abuse prior to puberty and the death in childhood of an immediate family member not from suicide or homicide were significantly more likely in the non-adherent group and other negative childhood events trended toward being more likely. Those with incomplete adherence had higher depressive symptom severity and post-traumatic stress disorder (PTSD). In multivariable analyses, childhood trauma, depression, and financial sacrifice remained associated with incomplete adherence. Discussion This is the first study to examine the effect of childhood trauma, depression and PTSD on HIV medication adherence in a low income country facing a significant burden of HIV. Allocating spending on HIV/AIDS toward integrating mental health services with HIV care is essential to the creation of systems that enhance medication adherence

    During studies to extend the half-life of crystalline nanoformulated antiretroviral therapy (nanoART) the mixed lineage kinase-3 inhibitor URMC-099, developed as an adjunctive neuroprotective agent was shown to facilitate antiviral responses. Long-acting ritonavir-boosted atazanavir (nanoATV/r) nanoformulations co-administered with URMC-099 reduced viral load and the numbers of HIV-1 infected CD4+ T-cells in lymphoid tissues more than either drug alone in infected humanized NOD/SCID/IL2Rγc-/- mice. The drug effects were associated with sustained ART depots. Proteomics analyses demonstrated that the antiretroviral responses were linked to affected phagolysosomal storage pathways leading to sequestration of nanoATV/r in Rab-associated recycling and late endosomes; sites associated with viral maturation. URMC-099 administered with nanoATV induced a dose-dependent reduction in HIV-1p24 and reverse transcriptase activity. This drug combination offers a unique chemical marriage for cell-based viral clearance. From the Clinical Editor: Although successful in combating HIV-1 infection, the next improvement in antiretroviral therapy (nanoART) would be to devise long acting therapy, such as intra-cellular depots. In this report, the authors described the use of nanoformulated antiretroviral therapy given together with the mixed lineage kinase-3 inhibitor URMC-099, and showed that this combination not only prolonged drug half-life, but also had better efficacy. The findings are hoped to be translated into the clinical setting in the future. PMID:26472049

    BACKGROUND Peripartum administration of single-dose nevirapine reduces mother-to-child transmission of human immunodeficiency virus type 1 (HIV-1) but selects for nevirapine-resistant virus. METHODS In seven African countries, women infected with HIV-1 whose CD4+ T-cell counts were below 200 per cubic millimeter and who either had or had not taken single-dose nevirapine at least 6 months before enrollment were randomly assigned to receive antiretroviral therapy with tenofovir–emtricitabine plus nevirapine or tenofovir-emtricitabine plus lopinavir boosted by a low dose of ritonavir. The primary end point was the time to confirmed virologic failure or death. RESULTS A total of 241 women who had been exposed to single-dose nevirapine began the study treatments (121 received nevirapine and 120 received ritonavir-boosted lopinavir). Significantly more women in the nevirapine group reached the primary end point than in the ritonavir-boosted lopinavir group (26% vs. 8%) (adjusted P = 0.001). Virologic failure occurred in 37 (28 in the nevirapine group and 9 in the ritonavir-boosted lopinavir group), and 5 died without prior virologic failure (4 in the nevirapine group and 1 in the ritonavir-boosted lopinavir group). The group differences appeared to decrease as the interval between single-dose nevirapine exposure and the start of antiretroviral therapy increased. Retrospective bulk sequencing of baseline plasma samples showed nevirapine resistance in 33 of 239 women tested (14%). Among 500 women without prior exposure to single-dose nevirapine, 34 of 249 in the nevirapine group (14%) and 36 of 251 in the ritonavir-boosted lopinavir group (14%) had virologic failure or died. CONCLUSIONS In women with prior exposure to peripartum single-dose nevirapine (but not in those without prior exposure), ritonavir-boosted lopinavir plus tenofovir–emtricitabine was superior to nevirapine plus tenofovir–emtricitabine for initial antiretroviral therapy.

    The examination of antibody responses in human immunodeficiency virus (HIV)-1-infected individuals in the setting of antiretroviral treatment (ART) interruption can provide insight into the evolution of antibody responses during viral rebound. In this study, we assessed antibody responses in 20 subjects in AIDS Clinical Trials Group A5187, wherein subjects were treated with antiretroviral therapy during acute/early HIV-1 infection, underwent analytic treatment interruption, and subsequently demonstrated viral rebound. Our data suggest that early initiation of ART arrests the maturation of HIV-1-specific antibody responses, preventing epitope diversification of antibody binding and the development of functional neutralizing capacity. Antibody responses do not appear permanently blunted, however, because viral rebound triggered the resumption of antibody maturation in our study. We also found that antibody responses measured by these assays did not predict imminent viral rebound. These data have important implications for the HIV-1 vaccine and eradication fields.

    Objectives To characterize antiretroviral therapy (ART) adherence across different programmes and examine the relationship between individual and programme characteristics and incomplete adherence among ART clients in sub-Saharan Africa. Design A cross-sectional study. Methods Systematically selected ART clients (≥18 years; on ART ≥6 months) attending 18 facilities in three countries (250 clients/facility) were interviewed. Client self-reports (3-day, 30-day, Case Index ≥48 consecutive hours of missed ART), healthcare provider estimates and the pharmacy medication possession ratio (MPR) were used to estimate ART adherence. Participants from two facilities per country underwent HIV RNA testing. Optimal adherence measures were selected on the basis of degree of association with concurrent HIV RNA dichotomized at less than or greater/equal to 1000 copies/ml. Multivariate regression analysis, adjusted for site-level clustering, assessed associations between incomplete adherence and individual and programme factors. Results A total of 4489 participants were included, of whom 1498 underwent HIV RNA testing. Nonadherence ranged from 3.2% missing at least 48 consecutive hours to 40.1% having an MPR of less than 90%. The percentage with HIV RNA at least 1000 copies/ml ranged from 7.2 to 17.2% across study sites (mean = 9.9%). Having at least 48 consecutive hours of missed ART was the adherence measure most strongly related to virologic failure. Factors significantly related to incomplete adherence included visiting a traditional healer, screening positive for alcohol abuse, experiencing more HIV symptoms, having an ART regimen without nevirapine and greater levels of internalized stigma. Conclusion Results support more in-depth investigations of the role of traditional healers, and the development of interventions to address alcohol abuse and internalized stigma among treatment-experienced adult ART patients.

    Some people living with HIV (PLHIV) refuse to initiate antiretroviral therapy (ART) despite availability. Between March 2010 and September 2011, using a social ecological framework, we investigated barriers to ART initiation in Lusaka, Zambia. In-depth interviews were conducted with PLHIV who were offered treatment but declined (n=37), ART staff (n=5), faith healers (n=5), herbal medicine providers (n=5), and home-based care providers (n=5). One focus group discussion with lay HIV counselors and observations in the community and at an ART clinic were conducted. Interviews were audio-recorded, transcribed, and translated, coded using Atlas ti, and analyzed using latent content analysis. Lack of self-efficacy, negative perceptions of medication, desire for normalcy, and fear of treatment-induced physical body changes, all modulated by feeling healthy, undermined treatment initiation. Social relationships generated and perpetuated these health and treatment beliefs. Long waiting times at ART clinics, concerns about long-term availability of treatment, and taking strong medication amidst livelihood insecurity also dissuaded PLHIV from initiating treatment. PLHIV opted for herbal remedies and faith healing as alternatives to ART, with the former being regarded as effective as ART, while the latter contributed to restoring normalcy through the promise of being healed. Barriers to treatment initiation were not mutually exclusive. Some coalesced to undermine treatment initiation. Ensuring patients initiate ART requires interventions at different levels, addressing, in particular, people's health and treatment beliefs, changing perceptions about effectiveness of herbal remedies and faith healing, improving ART delivery to attenuate social and economic costs and allaying concerns about future non-availability of treatment.

    Nearly perfect adherence to demanding antiretroviral therapy (ART) is now recognized as essential for HIV-positive patients to realize its life sustaining benefits. Despite the dire consequences of non-adherence, a large number of patients do not follow their ART regimen. While many factors influence adherence, the literature is dominated by studies on only one or a small set of them. Multivariate, theory-based models of adherence behavior are of great interest. The current study tested one such model, the Information, Motivation and Behavioral Skills (IMB) model of ART adherence (Fisher et al., under review). A sample of HIV-positive patients on ART in clinical care in Puerto Rico (N=200) provided data on adherence-related information, motivation and behavioral skills as well as adherence behavior per se. Structural equation model tests used to assess the propositions of the IMB model of ART adherence provided support for the interrelations between the elements proposed by the model and extended previous work. Implications for future research and intervention development are discussed. PMID:16036253

    Our laboratory has pioneered the development of long-acting nanoformulations of antiretroviral therapy (nanoART). NanoART serves to improve drug compliance, toxicities, and access to viral reservoirs. These all function to improve treatment of human immunodeficiency virus (HIV) infection. Formulations are designed to harness the carrying capacities of mononuclear phagocytes (MP; monocytes and macrophages) and to use these cells as Trojan horses for drug delivery. Such a drug distribution system limits ART metabolism and excretion while facilitating access to viral reservoirs. Our prior works demonstrated a high degree of nanoART sequestration in macrophage recycling endosomes with broad and sustained drug tissue biodistribution and depots with limited untoward systemic toxicities. Despite such benefits, the effects of particle carriage on the cells’ functional capacities remained poorly understood. Thus, we employed pulsed stable isotope labeling of amino acids in cell culture to elucidate the macrophage proteome and assess any alterations in cellular functions that would affect cell-drug carriage and release kinetics. NanoART-MP interactions resulted in the induction of a broad range of activation-related proteins that can enhance phagocytosis, secretory functions, and cell migration. Notably, we now demonstrate that particle-cell interactions serve to enhance drug loading while facilitating drug tissue depots and transportation. PMID:23544708

    HIV has become a highly treatable disease due to advances in antiretroviral therapy (ART). Additionally, HIV-infected individuals often take opiates, barbiturates, and benzodiazepines to treat co-occurring conditions, including pain and symptoms of HIV. We sought to examine prescription medication misuse by surveying 295 HIV-infected patients receiving ART. Participants answered questions about their demographics, alcohol and other drug use, psychiatric diagnoses, ART adherence and side effects, and quality of life. 11% of our sample acknowledged prescription medication misuse. In regression analysis, prescription medication misusers were more likely to report any drinking to intoxication (OR=4.31, 95% CI: 1.35-13.76, p=0.013), reported greater severity of ART side effects (OR=1.05, 95% CI: 1.01-1.10, p=0.041), and demonstrated poorer cognitive functioning (OR=0.97, 95% CI: 0.94-0.99, p=0.048) compared to those who did not misuse prescription medications. Special care should be taken by medical providers before prescribing medications that may be abused or diverted. Patients should also be screened for aberrant use, even if not prescribed. ART side effects, cognitive deficits, and alcohol abuse may serve as risk factors or indicators of prescription medication misuse, and should be monitored. PMID:25245428

    Depression and anxiety are common among HIV-infected people and rank among the strongest predictors of non-adherence to antiretroviral therapy (ART). This longitudinal study aimed to assess whether symptoms of anxiety and depression are predictors of non-adherence among patients initiating ART at two public referral centers (n=293) in Belo Horizonte, Brazil. Prevalence of severe anxiety and depression symptoms before starting ART was 12.6% and 5.8%, respectively. Severe anxiety was a predictor of non-adherence to ART during follow-up period (RH=1.87; 95% CI=1.14–3.06) adjusted for low education, unemployment, alcohol use in the last month and symptoms of AIDS; while a history of injection drug use had borderline statistical significance with non-adherence. These findings suggest that using a brief screening procedure to assess anxiety and depression symptoms before initiating ART help identify individuals for interventions to improve adherence and quality of life.

    For more than two decades, CD4 cell count measurements have been central to understanding HIV disease progression, making important clinical decisions, and monitoring the response to antiretroviral therapy (ART). In well resourced settings, the monitoring of patients on ART has been supported by routine virological monitoring. Viral load monitoring was recommended by WHO in 2013 guidelines as the preferred way to monitor people on ART, and efforts are underway to scale up access in resource-limited settings. Recent studies suggest that in situations where viral load is available and patients are virologically suppressed, long-term CD4 monitoring adds little value and stopping CD4 monitoring will have major cost savings. CD4 cell counts will continue to play an important part in initial decisions around ART initiation and clinical management, particularly for patients presenting late to care, and for treatment monitoring where viral load monitoring is restricted. However, in settings where both CD4 cell counts and viral load testing are routinely available, countries should consider reducing the frequency of CD4 cell counts or not doing routine CD4 monitoring for patients who are stable on ART.

    This paper reviews the data sources and methods used to estimate the number of people on, and coverage of, antiretroviral therapy (ART) programmes in low- and middle-income countries and to monitor the progress towards the "3 by 5" target set by WHO and UNAIDS. We include a review of the data sources used to estimate the coverage of ART programmes as well as the efforts made to avoid double counting and over-reporting. The methods used to estimate the number of people in need of ART are described and expanded with estimates of treatment needs for children, both for ART and for cotrimoxazole prophylaxis. An estimated 6.5 million people were in need of treatment in low- and middle-income countries by the end of 2004, including 660,000 children under age 15 years. The mid-2005 estimate of 970,000 people receiving ART in low- and middle-income countries (with an uncertainty range 840,000-1,100,000) corresponds to a coverage of 15% of people in need of treatment.

    Background. Although human immunodeficiency virus (HIV) infection and antiretroviral therapy (ART) affect mitochondrial DNA (mtDNA) content and function, comprehensive evaluations of their effects on mitochondria in muscle, adipose tissue, and blood cells are limited. Methods. Mitochondrial DNA quantification, mitochondrial genome sequencing, and gene expression analysis were performed on muscle, adipose tissue, and peripheral blood mononuclear cell (PBMC) samples from untreated HIV-positive patients, HIV-positive patients receiving nucleoside reverse transcriptase inhibitor (NRTI)–based ART, and HIV-negative controls. Results. The adipose tissue mtDNA/nuclear DNA (nDNA) ratio was increased in untreated HIV-infected patients (ratio, 353) and decreased in those receiving ART (ratio, 162) compared with controls (ratio, 255; P < .05 for both comparisons); the difference between the 2 HIV-infected groups was also significant (P = .002). In HIV-infected participants, mtDNA/nDNA in adipose tissue correlated with the level of activation (CD38+/HLA-DR+) for CD4+ and CD8+ lymphocytes. No significant differences in mtDNA content were noted in muscle or PMBCs among groups. Exploratory DNA microarray analysis identified differential gene expression between patient groups, including a subset of adipose tissue genes. Conclusions. HIV infection and ART have opposing effects on mtDNA content in adipose tissue; immune activation may mediate the effects of HIV, whereas NRTIs likely mediate the effects of ART.

    Pneumocystis jirovecii pneumonia (PJP) in patients with HIV infection can, in rare cases, present with pulmonary nodules that histologically involve granulomatous inflammation. This report describes an intriguing case of granulomatous PJP with pulmonary nodules after commencing antiretroviral therapy (ART) in an HIV-infected patient without respiratory signs or symptoms. Diagnosis of granulomatous PJP was only achieved through thoracoscopic lung biopsy. This case suggests that granulomatous PJP should be considered in the differential diagnosis of pulmonary nodules in HIV-infected patients for unmasking immune reconstitution inflammatory syndrome manifestation after initiation of ART.

    Annual fasting during the month of Ramadan is observed in Muslim countries, some of which have widespread HIV infection. We studied treatment adherence and customary practices among 142 fasting `FT' and 101 non-fasting `NFT' patients on anti-retroviral therapy (ART) in Nigeria. Adherence on ART among FT and NFT patients was similar during Ramadan, 96% and 98%, and ever since commencement of ART, 80% and 88%, respectively. FT patients altered their typical daily behaviors by advancing morning and delaying evening doses thereby prolonging dosing intervals, eating heavier meals pre-dawn and on breakfast at sunset (78%), and changing or reducing their sleeping and waking times (40%). This preliminary study suggests that adherence and drug taking frequency appear uncompromised in FT HIV infected patients on ARVs. PMID:18521736

    Introduction Adherence to antiretroviral therapy (ART) is known to be challenging among adolescents living with HIV/AIDS, notwithstanding the life-saving importance of this therapy. Of the global total number of adolescents living with HIV in 2013, 83% reside in sub-Saharan Africa. The study aimed to identify facilitators of and barriers to antiretroviral treatment adherence among adolescents in Ghana. Methods A cross-sectional qualitative study using semi-structured interviews for data collection was carried out among adolescents (aged 12–19 years) at the adolescents HIV clinic at the Korle-Bu Teaching Hospital in Ghana. Predominantly open-ended questions relating to ART were used. Interviews were done until saturation. In total, 19 interviews were conducted. Analysis was done manually to maintain proximity with the text. Findings The main facilitators were support from health care providers, parental support, patient’s knowledge of disease and self-motivation, patient’s perceived positive outcomes, and dispensed formulation. The identified barriers were patient’s forgetfulness to take medicines, perceived stigmatization due to disclosure, financial barriers, and adverse effects of ART. Support from health care workers was the most frequently mentioned facilitator, and patient’s forgetfulness and perceived stigmatization after disclosure were the most frequently mentioned barriers. Self-motivation (knowledge induced) to adhere to treatment was a specific facilitator among older adolescents. Conclusion Continuous information provision in addition to unflinching support from health care workers and parents or guardians may improve adherence among adolescents. Also, interventions to reduce patient forgetfulness may be beneficial. A multi-sectorial approach would be needed to address adolescent disclosure of HIV/AIDS status. PMID:27042024

    Effective treatment of HIV infection with antiretroviral drugs significantly improve prognosis. Reduction of mortality and life prolongations in patients receiving such therapy have been also connected with the risk of side effects development. Among these complications metabolic disturbances such as lipodystrophy, dyslipidaemia, and insulin resistance which are present according some authors in up to 50% of patients receiving HAART play an important role. In spite of different investigations molecular basis of lipodystrophy development during HAART have not be fully understood, and the latest research revealed a lot of new aspects connected w adipocyte tissue pathophysiology, which were not taken up to know into consideration. In the presented publication the most important information about pathogenesis of lipodystrophy development in HIV infected patients treated with ARV drugs have been presented. PMID:21591364

    Background Access to highly active antiretroviral therapy (HAART) is expanding in Latin America. Many patients require second and third line therapy due to toxicity, tolerability, failure, or a combination of factors. The need for third line HAART, essential for program planning, is not known. Methods Antiretroviral-naïve patients ≥18 years who started first HAART after January 1, 2000 in Caribbean, Central and South America Network (CCASAnet) sites in Argentina, Brazil, Honduras, Mexico, and Peru were included. Clinical trials participants were excluded. Third line HAART was defined as use of darunavir, tipranavir, etravirine, enfuvirtide, maraviroc or raltegravir. Need for third line HAART was defined as virologic failure while on second line HAART. Results Of 5853 HAART initiators followed for a median of 3.5 years, 310 (5.3%) failed a second line regimen and 44 (0.8%) received a third line regimen. Cumulative incidence of failing a 2nd or starting a 3rd line regimen was 2.7% and 6.0% three and five years after HAART initiation, respectively. Predictors at HAART initiation for failing a second or starting a third line included female sex (hazard ratio [HR] = 1.54, 95% confidence interval [CI] 1.18–2.00, p = 0.001), younger age (HR = 2.76 for 20 vs. 40 years, 95% CI 1.86–4.10, p<0.001), and prior AIDS (HR = 2.17, 95% CI 1.62–2.90, p<0.001). Conclusions Third line regimens may be needed for at least 6% of patients in Latin America within 5 years of starting HAART, a substantial proportion given the large numbers of patients on HAART in the region. Improved accessibility to third line regimens is warranted. PMID:25221931

    With millions in need of HIV antiretroviral therapy (ART) in the developing world, and scarce human and fiscal resources available, we conducted a formative evaluation of scale-up operations at clinics associated with AIDS Healthcare Foundation in Africa to identify lessons learned for improving scale-up efficiency. Site visits were made to six selected clinics in Uganda, Zambia, and South Africa, during which semistructured interviews with key stake-holders and observation of client flows and clinic operations were performed. This evaluation revealed the following lessons related to factors that are critical to efficient ART scale-up: (1) to ensure steady ART uptake, it is important to involve the community and community leaders in outreach, HIV education, and program decision-making; (2) minimizing bottlenecks to smooth patient flow requires efficient staff allocation to appropriate clinical duties, streamlined clinic visit schedule protocols, and tapping clients and the HIV community as a key source of labor; (3) to minimize clients dropping out of care, structures should be developed that enable clients to provide support and a "safety net" for helping each other remain in care; (4) computerized record management systems are essential for accurate antiretroviral inventory and dispensing records, quality assurance monitoring, and client enrollment records and visit scheduling; (5) effective organizational management and human resource policies are essential to maintain high job performance and satisfaction and limit burnout; (6) to maximize impact on social and economic health, it is important for ART programs to develop effective mechanisms for coordinating and referring clients to support service organizations.

    Among people living with HIV (PLWH), adherence to antiretroviral therapy (ART) is crucial for health, but patients face numerous challenges achieving sustained lifetime adherence. We conducted six focus groups with 56 PLWH regarding ART adherence barriers and collected sociodemographics and ART histories. Participants were recruited through clinics and AIDS service organizations in North Carolina. Dedoose software was used to support thematic analysis. Participants were 59% male, 77% black, aged 23-67 years, and living with HIV 4-20 years. Discussions reflected the fluid, complex nature of ART adherence. Maintaining adherence required participants to indefinitely assert consistent control across multiple areas including: their HIV disease, their own bodies, health care providers, and social systems (e.g., criminal justice, hospitals, drug assistance programs). Participants described limited control over treatment options, ART's impact on their body, and inconsistent access to ART and subsequent inability to take ART as prescribed. When participants felt they had more decision-making power, intentionally choosing whether and how to take ART was not exclusively a decision about best treating HIV. Instead, through these decisions, participants tried to regain some amount of power and control in their lives. Supportive provider relationships assuaged these struggles, while perceived side-effects and multiple co-morbidities further complicated adherence. Adherence interventions need to better convey adherence as a continuous, changing process, not a fixed state. A perspective shift among care providers could also help address negative consequences of the perceived power struggles and pressures that may drive patients to exert control via intentional medication taking practices.

    Objective To demonstrate the feasibility of integrated screening for cryptococcal antigenemia and tuberculosis (TB) prior to antiretroviral therapy (ART) initiation and to assess disease specific and all-cause mortality in the first 6 months of follow-up. Methods We enrolled a cohort of HIV-infected, ART-naïve adults with CD4 counts ≤ 250 cells/µL in rural Uganda who were followed for 6 months after ART initiation. All subjects underwent screening for TB; those with CD4 ≤ 100 cells/µL also had cryptococcal antigen (CrAg) screening. For those who screened positive, standard treatment for TB or preemptive treatment for cryptococcal infection was initiated, followed by ART two weeks later. Results Of 540 participants enrolled, pre-ART screening detected 10.6% (57/540) with prevalent TB and 6.8% (12/177 with CD4 count ≤ 100 cells/µL) with positive serum CrAg. After ART initiation, 13 (2.4%) patients were diagnosed with TB and one patient developed cryptococcal meningitis. Overall 7.2% of participants died (incidence rate 15.6 per 100 person years at risk). Death rates were significantly higher among subjects with TB and cryptococcal antigenemia compared to subjects without these diagnoses. In multivariate analysis, significant risk factors for mortality were male sex, baseline anemia of hemoglobin ≤ 10 mg/dL, wasting defined as body mass index ≤ 15.5 kg/m2, and opportunistic infections (TB, positive serum CrAg). Conclusion Pre-ART screening for opportunistic infections detects many prevalent cases of TB and cryptococcal infection. However, severely immunosuppressed and symptomatic HIV patients continue to experience high mortality after ART initiation. PMID:25761234

    It has been shown that socioeconomic factors are associated with the prognosis of several chronic diseases; however, there is no recent systematic review of their effect on HIV treatment outcomes. We aimed to review the evidence regarding the existence of an association of socioeconomic status with virological and immunological response to antiretroviral therapy (ART). We systematically searched the current literature using the database PubMed. We identified and summarized original research studies in high-income countries that assessed the association between socioeconomic factors (education, employment, income/financial status, housing, health insurance, and neighbourhood-level socioeconomic factors) and virological response, immunological response, and ART nonadherence among people with HIV-prescribed ART. A total of 48 studies met the inclusion criteria (26 from the United States, six Canadian, 13 European, and one Australian), of which 14, six, and 35 analysed virological, immunological, and ART nonadherence outcomes, respectively. Ten (71%), four (67%), and 23 (66%) of these studies found a significant association between lower socioeconomic status and poorer response, and none found a significant association with improved response. Several studies showed that adjustment for nonadherence attenuated the association between socioeconomic status and ART response. Our review provides strong support that socioeconomic disadvantage is associated with poorer response to ART. However, most studies have been conducted in settings such as the United States without universal free healthcare access. Further study in settings with free access to ART could help assess the impact of socioeconomic status on ART outcomes and the mechanisms by which it operates. PMID:26919732

    Increased activity of IDO, which catalyzes the degradation of Trp into kynurenine (Kyn), is observed during HIV/SIV infection, and it may contribute to the persistence of HIV/SIV by suppressing antiviral T cell responses. We administered the IDO inhibitor 1-methyl-d-tryptophan (d-1mT) for 13 days to SIV-infected rhesus macaques receiving antiretroviral therapy (ART). d-1mT treatment increased the plasma levels of Trp, without reducing the levels of Kyn, suggesting only a partial effect on IDO enzymatic activity. Surprisingly, d-1mT significantly reduced the virus levels in plasma and lymph nodes of ART-treated animals with incomplete responsiveness to ART. In SIV-infected animals that were not receiving ART, d-1mT was ineffective in reducing the plasma viral load and had only a marginal effect on the plasma Kyn/Trp ratio. Increased IDO and TGF-beta mRNA expression in lymph nodes of ART-treated macaques after d-1mT treatment suggested that compensatory counterregulatory mechanisms were activated by d-1mT, which may account for the lack of effect on plasma Kyn. Finally, d-1mT did not interfere with the ART-induced T cell dynamics in lymph nodes (increased frequency of total CD4 T cells, increase of CD8 T cells expressing the antiapoptotic molecule Bcl2, and reduction of regulatory T cells). Thus, d-1mT appeared to synergize with ART in inhibiting viral replication and did not interfere with the beneficial immunologic effects of ART. Further studies are required to elucidate the immunologic or virologic mechanism by which d-1mT inhibited SIV replication in vivo. PMID:19299731

    Background Although HIV treatment as prevention (TasP) via early antiretroviral therapy (ART) has proven to reduce transmissions among HIV-serodiscordant couples, its full implementation in developing countries remains a challenge. In this study, we determine whether China's current HIV treatment program prevents new HIV infections among discordant couples in rural China. Methods A prospective, longitudinal cohort study was conducted from June 2009 to March 2011, in rural Yunnan. A total of 1,618 HIV-discordant couples were eligible, 1,101 were enrolled, and 813 were followed for an average of 1.4 person-years (PY). Routine ART was prescribed to HIV-positive spouses according to eligibility (CD4<350 cells/µl). Seroconversion was used to determine HIV incidence. Results A total of 17 seroconversions were documented within 1,127 PY of follow-up, for an overall incidence of 1.5 per 100 PY. Epidemiological and genetic evidence confirmed that all 17 seroconverters were infected via marital secondary sexual transmission. Having an ART-experienced HIV-positive partner was associated with a lower rate of seroconvertion compared with having an ART-naïve HIV-positive partner (0.8 per 100 PY vs. 2.4 per 100 PY, HR = 0.34, 95%CI = 0.12–0.97, p = 0.0436). While we found that ART successfully suppressed plasma viral load to <400 copies/ml in the majority of cases (85.0% vs. 19.5%, p<0.0001 at baseline), we did document five seroconversions among ART-experienced subgroup. Conclusions ART is associated with a 66% reduction in HIV incidence among discordant couples in our sample, demonstrating the effectiveness of China's HIV treatment program at preventing new infections, and providing support for earlier ART initiation and TasP implementation in this region.

    Objective There is limited research investigating the possible mechanisms of how starting combination antiretroviral therapy (cART) at a higher CD4+ cell count decreases mortality. This study investigated the association between initiating cART with short-term and long-term achievement of viral suppression; emergence of any drug resistance and of an AIDS-defining illness (ADI); long-term treatment adherence; and all-cause mortality. Methods This retrospective cohort study included 4120 naive patients who initiated cART between 2000 and 2012. Patients were followed until 2013, death or until the last contact date (varied by outcome). The main exposure was the interaction between period of cART initiation (2000–2006 and 2007–2012) and CD4+ cell count at cART initiation (<500 versus ≥500 cells/μl). We considered both baseline and longitudinal covariates. We fitted different multivariable models using cross-sectional and longitudinal statistical methods, depending on the outcome. Results Patients who initiated cART with a CD4+ cell count at least 500 cells/μl in 2007–2012 had an increased likelihood of achieving viral suppression at 9 months and of maintaining an adherence level of at least 95% over time, and the lowest probability of developing any resistance and an ADI during follow-up. These patients were not the ones with the highest likelihood of maintaining viral suppression over time, most likely due to viral load blips experienced during the follow-up. Conclusion The outcomes in this study likely play an important role in explaining the positive impact of early cART initiation on mortality. These results should alleviate some of the concerns clinicians may have when initiating cART in patients with high CD4+s as recommended by current treatment guidelines. PMID:26165354

    Background As the resource implications of expanding anti-retroviral therapy (ART) are likely to be large, there is a need to explore its cost-effectiveness. So far, there is no such information available from Ethiopia. Objective To assess the cost-effectiveness of ART for routine clinical practice in a district hospital setting in Ethiopia. Methods We estimated the unit cost of HIV-related care from the 2004/5 fiscal year expenditure of Arba Minch Hospital in southern Ethiopia. We estimated outpatient and inpatient service use from HIV-infected patients who received care and treatment at the hospital between January 2003 and March 2006. We measured the health effect as life years gained (LYG) for patients receiving ART compared with those not receiving such treatment. The study adopted a health care provider perspective and included both direct and overhead costs. We used Markov model to estimate the lifetime costs, health benefits and cost-effectiveness of ART. Findings ART yielded an undiscounted 9.4 years expected survival, and resulted in 7.1 extra LYG compared to patients not receiving ART. The lifetime incremental cost is US$2,215 and the undiscounted incremental cost per LYG is US$314. When discounted at 3%, the additional LYG decreases to 5.5 years and the incremental cost per LYG increases to US$325. Conclusion The undiscounted and discounted incremental costs per LYG from introducing ART were less than the per capita GDP threshold at the base year. Thus, ART could be regarded as cost-effective in a district hospital setting in Ethiopia. PMID:19615069

    Widespread use of antiretroviral agents and increasing occurrence of human immunodeficiency virus (HIV) strains resistant to these drugs have given rise to a number of important issues. Some of these concerns are distinct from the obvious question of the relationship between drug resistance and treatment failure and have potentially widespread public health implications. The relevant issues include but are not limited to the following: (1) frequency with which drug-resistant virus may be transmitted via sexual, intravenous, or mother-to-child routes; (2) ability of drug-resistant variants to be transmitted, a question that relates, in part, to the relative fitness of such strains; (3) effectiveness of antiviral therapy in diminishing viral burden in both blood and genital secretions, and whether this may be compromised in persons harboring resistant virus; and (4) importance of patient adherence to antiviral therapy and its relationship to sustained reduction in viral load to minimize the appearance in and transmission of drug-resistant virus from both blood and genital secretions. Thus, prevention of both development of HIV drug resistance as well as transmission of drug-resistant variants is a central issue of public health importance. Unless this topic is appropriately addressed, the likelihood is that drug-resistant variants of HIV, if able to successfully replicate, will sustain the epidemic and limit the effectiveness of antiviral therapy.

    Introduction In response to the increasing burden of HIV, the Ugandan government has employed different service delivery models since 2004 that aim to reduce costs and remove barriers to accessing HIV care. These models include community-based approaches to delivering antiretroviral therapy (ART) and delegating tasks to lower-level health workers. This study aimed to provide data on annual ART cost per client among three different service delivery models in Uganda. Methods Costing data for the entire year 2012 were retrospectively collected as part of a larger task-shifting study conducted in three organizations in Uganda: Kitovu Mobile (KM), the AIDS Support Organisation (TASO) and Uganda Cares (UC). A standard cost data capture tool was developed and used to retrospectively collect cost information regarding antiretroviral (ARV) drugs and non-ARV drugs, ART-related lab tests, personnel and administrative costs. A random sample of four TASO centres (out of 11), four UC clinics (out of 29) and all KM outreach units were selected for the study. Results Cost varied across sites within each organization as well as across the three organizations. In addition, the number of annual ART visits was more frequent in rural areas and through KM (the community distribution model), which played a major part in the overall annual ART cost. The annual cost per client (in USD) was $404 for KM, $332 for TASO and $257 for UC. These estimates were lower than previous analyses in Uganda or the region compared to data from 2001 to 2009, but comparable with recent estimates using data from 2010 to 2013. ARVs accounted for the majority of the total cost, followed by personnel and operational costs. Conclusions The study provides updated data on annual cost per ART visit for three service delivery models in Uganda. These data will be vital for in-country budgetary efforts to ensure that universal access to ART, as called for in the 2015 World Health Organization (WHO) guidelines, is

    Background We examined efficacy, toxicity, relapse, cost, and quality-of-life thresholds of hypothetical HIV cure interventions that would make them cost-effective compared to life-long antiretroviral therapy (ART). Methods We used a computer simulation model to assess three HIV cure strategies: Gene Therapy, Chemotherapy, and Stem Cell Transplantation (SCT), each compared to ART. Efficacy and cost parameters were varied widely in sensitivity analysis. Outcomes included quality-adjusted life expectancy, lifetime cost, and cost-effectiveness in dollars/quality-adjusted life year ($/QALY) gained. Strategies were deemed cost-effective with incremental cost-effectiveness ratios <$100,000/QALY. Results For patients on ART, discounted quality-adjusted life expectancy was 16.4 years and lifetime costs were $591,400. Gene Therapy was cost-effective with efficacy of 10%, relapse rate 0.5%/month, and cost $54,000. Chemotherapy was cost-effective with efficacy of 88%, relapse rate 0.5%/month, and cost $12,400/month for 24 months. At $150,000/procedure, SCT was cost-effective with efficacy of 79% and relapse rate 0.5%/month. Moderate efficacy increases and cost reductions made Gene Therapy cost-saving, but substantial efficacy/cost changes were needed to make Chemotherapy or SCT cost-saving. Conclusions Depending on efficacy, relapse rate, and cost, cure strategies could be cost-effective compared to current ART and potentially cost-saving. These results may help provide performance targets for developing cure strategies for HIV. PMID:25397616

    Background The CD4 cell count or percent (CD4%) at the start of combination antiretroviral therapy (cART) are important prognostic factors in children starting therapy and an important indicator of program performance. We describe trends and determinants of CD4 measures at cART initiation in children from low-, middle- and high-income countries. Methods We included children aged <16 years from clinics participating in a collaborative study spanning sub-Saharan Africa, Asia, Latin America and the United States of America (USA). Missing CD4 values at cART start were estimated through multiple imputation. Severe immunodeficiency was defined according to World Health Organization criteria. Analyses used generalized additive mixed models adjusted for age, country and calendar year. Results 34,706 children from nine low-income, six lower middle-income, four upper middle-income countries and one high-income country (United States of America, USA) were included; 20,624 children (59%) had severe immunodeficiency. In low-income countries the estimated prevalence of children starting cART with severe immunodeficiency declined from 76% in 2004 to 63% in 2010. Corresponding figures for lower middle-income countries were from 77% to 66% and for upper middle-income countries from 75% to 58%. In the USA, the percentage decreased from 42% to 19% during the period 1996 to 2006. In low- and middle-income countries infants and children aged 12-15 years had the highest prevalence of severe immunodeficiency at cART initiation. Conclusions Despite progress in most low- and middle-income countries, many children continue to start cART with severe immunodeficiency. Early diagnosis and treatment of HIV-infected children to prevent morbidity and mortality associated with immunodeficiency must remain a global public health priority. PMID:25501345

    The primary goal when devising strategies to define the start of therapy in HIV infected individuals is to avoid HIV disease progression and toxicity from antiretroviral therapy (ART). Intermediate goals includes, avoiding resistance by suppressing HIV replication, reducing transmission, limiting spread and diversity of HIV within the body and protecting the immune system from harm. The question of how early or late to start ART and achieve both primary and intermediate goals has dominated HIV research. The distinction between early and late treatment of HIV infection is currently a matter of CD4+ T cells count, a marker of immune status, rather than on viral load, a marker of virus replication. Discussions about respective benefits of early or delayed therapy, as well as the best CD4+ T cell threshold during the course of HIV infection at which ART is initiated remains inconclusive. Guidelines issued by various agencies, provide different initiation recommendations. This can be confusing for clinicians and policy-makers when determining the best time to initiate therapy. Optimizing ART initiation strategies are clearly complex and must be balanced between individual and broader public health needs. This review assesses available data that contributes to the debate on optimal time to initiate therapy in HIV-infected asymptomatic individuals. We also review reports on CD4+ T cell threshold to guide initiation of ART and finally discuss arguments for and against early or late initiation of ART. PMID:26475399

    There have been no paediatric randomised trials describing the effect of planned treatment interruptions (PTIs) of antiretroviral therapy (ART) on adherence, or evaluating acceptability of such a strategy. In PENTA 11, HIV-infected children were randomised to CD4-guided PTIs (n = 53) or continuous therapy (CT, n = 56). Carers, and children if appropriate, completed questionnaires on adherence to ART and acceptability of PTIs. There was no difference in reported adherence on ART between CT and PTI groups; non-adherence (reporting missed doses over the last 3 days or marking <100 % adherence since the last clinical visit on a visual analogue scale) was 18 % (20/111) and 14 % (12/83) on carer questionnaires in the CT and PTI groups respectively (odds ratios, OR (95 % CI) = 1.04 (0.20, 5.41), χ(2) (1) = 0.003, p = 0.96). Carers in Europe/USA reported non-adherence more often (31/121, 26 %) than in Thailand (1/73, 1 %; OR (95 % CI) = 54.65 (3.68, 810.55), χ(2) (1) = 8.45, p = 0.004). The majority of families indicated they were happy to have further PTIs (carer: 23/36, 64 %; children: 8/13, 62 %), however many reported more clinic visits during PTI were a problem (carer: 15/36, 42 %; children: 6/12, 50 %).

    Background Tuberculosis remains an important cause of death among patients infected with the human immunodeficiency virus (HIV). Robust data are lacking with regard to the timing for the initiation of antiretroviral therapy (ART) in relation to the start of antituberculosis therapy. Methods We tested the hypothesis that the timing of ART initiation would significantly affect mortality among adults not previously exposed to antiretroviral drugs who had newly diagnosed tuberculosis and CD4+ T-cell counts of 200 per cubic millimeter or lower. After beginning the standard, 6-month treatment for tuberculosis, patients were randomly assigned to either earlier treatment (2 weeks after beginning tuberculosis treatment) or later treatment (8 weeks after) with stavudine, lamivudine, and efavirenz. The primary end point was survival. Results A total of 661 patients were enrolled and were followed for a median of 25 months. The median CD4+ T-cell count was 25 per cubic millimeter, and the median viral load was 5.64 log10 copies per milliliter. The risk of death was significantly reduced in the group that received ART earlier, with 59 deaths among 332 patients (18%), as compared with 90 deaths among 329 patients (27%) in the later-ART group (hazard ratio, 0.62; 95% confidence interval [CI]; 0.44 to 0.86; P = 0.006). The risk of tuberculosis-associated immune reconstitution inflammatory syndrome was significantly increased in the earlier-ART group (hazard ratio, 2.51; 95% CI, 1.78 to 3.59; P<0.001). Irrespective of the study group, the median gain in the CD4+ T-cell count was 114 per cubic millimeter, and the viral load was undetectable at week 50 in 96.5% of the patients. Conclusions Initiating ART 2 weeks after the start of tuberculosis treatment significantly improved survival among HIV-infected adults with CD4+ T-cell counts of 200 per cubic millimeter or lower.

    In order to achieve optimal benefits of antiretroviral therapy (ART), caregivers of children receiving ART are required to attend routine clinic visits monthly and administer medication to the child as prescribed. Yet, the level of adherence to these behaviours varies considerably in many settings. As a way to achieve optimal adherence in rural KwaZulu-Natal, caregivers are required to attend routine counselling sessions at HIV treatment clinics that are centred on imparting information, motivation, and behavioural skills related to medication administration. According to the information-motivation-behavioural skills model, information related to adherence, motivation, and behavioural skills are necessary and fundamental determinants of adherence to ART. The purpose of the study was to observe and document the content of adherence counselling sessions that caregivers attending rural clinics in KwaZulu Natal receive. We observed 25 adherence counselling sessions, which lasted on average 8.1 minutes. Counselling typically consisted of counsellors recording patient attendance, reporting CD4 count and viral load results to caregivers, emphasising dose times, and asking caregivers to name their medications and dosage amounts. Patients were seldom asked to demonstrate how they measure the medication. They were also not probed for problems regarding treatment, even when an unsuppressed VL was reported to a caregiver. This paper calls attention to the sub-optimal level of counselling provided to patients on ART and the urgent need to standardise and improve the training, support, and debriefing provided to counsellors.

    There is considerable scientific evidence supporting the use of antiretroviral therapy (ART) in prevention of human immunodeficiency virus (HIV) and tuberculosis (TB) infections. The complex nature of the HIV and TB prevention responses, resource constraints, remaining questions about cost and feasibility, and the need to use a solid evidence base to make policy decisions, and the implementation challenges to translating trial data to operational settings require a well-organised and coordinated response to research in this area. To this end, we aimed to catalogue the ongoing and planned research activities that evaluate the impact of ART plus other interventions on HIV- and/or TB-related morbidity, mortality, risk behaviour, HIV incidence and transmission. Using a limited search methodology, 50 projects were identified examining ART as prevention, representing 5 regions and 52 countries with a global distribution. There are 24 randomised controlled clinical trials with at least 12 large randomised individual or community cluster trials in resource-constrained settings that are in the planning or early implementation stages. There is considerable heterogeneity between studies in terms of methodology, interventions and geographical location. While the identified studies will undoubtedly advance our understanding of the efficacy and effectiveness of ART for prevention, some key questions may remain unanswered or only partially answered. The large number and wide variety of research projects emphasise the importance of this research issue and clearly demonstrate the potential for synergies, partnerships and coordination across funding agencies.

    Our laboratory developed long-acting nanoformulations of antiretroviral therapy (nanoART) to improve drug compliance, reduce toxicities, and facilitate access of drug to viral reservoirs. These all function to inevitably improve treatment of human immunodeficiency virus (HIV) infection. Formulations are designed to harness the carrying capacities of mononuclear phagocytes (MP; monocytes and macrophages) and to use these cells as Trojan horses for drug delivery. Such a drug distribution system limits ART metabolism and excretion while facilitating access to viral reservoirs. Our prior works demonstrated a high degree of nanoART sequestration in macrophage recycling endosomes with broad and sustained drug tissue biodistribution and depots with limited untoward systemic toxicities. Despite such benefits, the effects of particle carriage on the cells' functional capacities remained poorly understood. Thus, we employed pulsed stable isotope labeling of amino acids in cell culture to elucidate the macrophage proteome and assess any alterations in cellular functions that would affect cell-drug carriage and release kinetics. NanoART-MP interactions resulted in the induction of a broad range of activation-related proteins that can enhance phagocytosis, secretory functions, and cell migration. Notably, we now demonstrate that particle-cell interactions serve to enhance drug loading while facilitating drug tissue depots and transportation. PMID:23544708

    The number of people living with HIV and AIDS (PLWHA) reached to almost 40 million, half of which are under antiretroviral treatment (ART). Although the introduction of this therapy significantly improved the life span and quality of PLWHA, metabolic complications of these people remains to be an important issue. These metabolic complications include hyperlipidemia, abnormal fat redistribution and diabetes mellitus, which are defined as lipodystrophy syndrome. Glucagon-like peptide-1 (GLP-1) is a neuropeptide secreted from intestinal L cells and recently developed GLP-1 receptor agonists (GLP-1RAs) stimulate insulin secretion, improve weight control and reduce cardiovascular outcomes. This class of drugs may be a valuable medication in the treatment of HIV-associated metabolic adverse effects and extend the life expectancy of patients infected with HIV. PMID:27515222

    Background In a randomized clinical trial of early versus standard antiretroviral therapy (ART) in HIV-infected adults with a CD4 cell count between 200 and 350 cells/mm3 in Haiti, early ART decreased mortality by 75%. We assessed the cost-effectiveness of early versus standard ART in this trial. Methods and Findings Trial data included use of ART and other medications, laboratory tests, outpatient visits, radiographic studies, procedures, and hospital services. Medication, laboratory, radiograph, labor, and overhead costs were from the study clinic, and hospital and procedure costs were from local providers. We evaluated cost per year of life saved (YLS), including patient and caregiver costs, with a median of 21 months and maximum of 36 months of follow-up, and with costs and life expectancy discounted at 3% per annum. Between 2005 and 2008, 816 participants were enrolled and followed for a median of 21 months. Mean total costs per patient during the trial were US$1,381 for early ART and US$1,033 for standard ART. After excluding research-related laboratory tests without clinical benefit, costs were US$1,158 (early ART) and US$979 (standard ART). Early ART patients had higher mean costs for ART (US$398 versus US$81) but lower costs for non-ART medications, CD4 cell counts, clinically indicated tests, and radiographs (US$275 versus US$384). The cost-effectiveness ratio after a maximum of 3 years for early versus standard ART was US$3,975/YLS (95% CI US$2,129/YLS–US$9,979/YLS) including research-related tests, and US$2,050/YLS excluding research-related tests (95% CI US$722/YLS–US$5,537/YLS). Conclusions Initiating ART in HIV-infected adults with a CD4 cell count between 200 and 350 cells/mm3 in Haiti, consistent with World Health Organization advice, was cost-effective (US$/YLS <3 times gross domestic product per capita) after a maximum of 3 years, after excluding research-related laboratory tests.

    HIV increases the risk of liver disease as do two common coinfections, hepatitis B and C viruses (HBV and HCV). However, whether combination antiretroviral therapy (cART) reverses or exacerbates hepatic fibrosis remains unclear.This was an observational retrospective study. cART-naïve HIV-infected subjects without a history of substance abuse (including alcohol) had liver disease stage determined by aspartate aminotransferase-to-platelet ratio indices (APRIs) and fibrosis-4 (FIB-4) before and 24 and 48 weeks after cART. All the data were retrieved from previously established cohorts. Values before and after cART were compared using Wilcoxon test for paired samples. Regression analyses were used to determine factors associated with moderate-to-severe liver disease.Of the 1105 HIV-infected subjects, 120 were HBV coinfected and 64 were HCV coinfected. About 20% of HIV monoinfected participants had APRI and FIB-4 scores consistent with moderate-to-significant fibrosis compared to ∼36% of HIV-HBV coinfected and 67% to 77% of HIV-HCV coinfected participants. In adjusted analyses compared with HIV monoinfection, HBV coinfection was associated with 1.18-fold higher APRI (P < 0.001) and a 1.12-fold higher FIB-4 (P = 0.007) prior to cART; while HCV coinfection was associated with 1.94-fold higher APRI (P < 0.001) and a 1.43-fold higher FIB-4 (P < 0.001). After 48 weeks of cART, both fibrosis scores decreased in all subjects; however, HCV coinfection was still associated with higher fibrosis scores at week 48 compared to HIV monoinfection.cART was associated with improvement in hepatic fibrosis scores in the majority of HIV-hepatitis coinfected and HIV-monoinfected Chinese participants.

    Abstract HIV increases the risk of liver disease as do two common coinfections, hepatitis B and C viruses (HBV and HCV). However, whether combination antiretroviral therapy (cART) reverses or exacerbates hepatic fibrosis remains unclear. This was an observational retrospective study. cART-naïve HIV-infected subjects without a history of substance abuse (including alcohol) had liver disease stage determined by aspartate aminotransferase-to-platelet ratio indices (APRIs) and fibrosis-4 (FIB-4) before and 24 and 48 weeks after cART. All the data were retrieved from previously established cohorts. Values before and after cART were compared using Wilcoxon test for paired samples. Regression analyses were used to determine factors associated with moderate-to-severe liver disease. Of the 1105 HIV-infected subjects, 120 were HBV coinfected and 64 were HCV coinfected. About 20% of HIV monoinfected participants had APRI and FIB-4 scores consistent with moderate-to-significant fibrosis compared to ∼36% of HIV–HBV coinfected and 67% to 77% of HIV–HCV coinfected participants. In adjusted analyses compared with HIV monoinfection, HBV coinfection was associated with 1.18-fold higher APRI (P < 0.001) and a 1.12-fold higher FIB-4 (P = 0.007) prior to cART; while HCV coinfection was associated with 1.94-fold higher APRI (P < 0.001) and a 1.43-fold higher FIB-4 (P < 0.001). After 48 weeks of cART, both fibrosis scores decreased in all subjects; however, HCV coinfection was still associated with higher fibrosis scores at week 48 compared to HIV monoinfection. cART was associated with improvement in hepatic fibrosis scores in the majority of HIV-hepatitis coinfected and HIV-monoinfected Chinese participants.

    Abstract Objective To assess the association between the employment status of human immunodeficiency virus (HIV)-infected individuals and adherence to antiretroviral therapy (ART). Methods We searched the Medline, Embase and Cochrane Central Register of Controlled Trials databases for studies reporting ART adherence and employment status published between January 1980 and September 2014. Information from a wide range of other sources, including the grey literature, was also analysed. Two independent reviewers extracted data on treatment adherence and study characteristics. Study data on the association between being employed and adhering to ART were pooled using a random-effects model. Between-study heterogeneity and sources of bias were evaluated. Findings The meta-analysis included 28 studies published between 1996 and 2014 that together involved 8743 HIV-infected individuals from 14 countries. The overall pooled odds ratio (OR) for the association between being employed and adhering to ART was 1.27 (95% confidence interval, CI: 1.04–1.55). The association was significant for studies from low-income countries (OR: 1.85, 95% CI: 1.58–2.18) and high-income countries (OR: 1.33, 95% CI: 1.02–1.74) but not middle-income countries (OR: 0.94, 95% CI: 0.62–1.42). In addition, studies published after 2011 and larger studies showed less association between employment and adherence than earlier and small studies, respectively. Conclusion Employed HIV-infected individuals, particularly those in low- and high-income countries, were more likely to adhere to ART than unemployed individuals. Further research is needed on the mechanisms by which employment and ART adherence affect each other and on whether employment-creation interventions can positively influence ART adherence, HIV disease progression and quality of life.

    OBJECTIVE To investigate neuropsychological performance (NP) during acute HIV infection (AHI) before and after combination antiretroviral therapy (cART). DESIGN Prospective study of Thai AHI participants examined at 3 and 6 months following initiation of cART. METHODS 36 AHI participants were evaluated pre-cART at median 19 days since HIV exposure and 3 and 6 months after cART with the Grooved Pegboard test (GP), Color Trails 1 & 2 (CT1, CT2), and Trail Making Test A (TM). Raw scores were standardized to 251 age-and-education-matched HIV-uninfected Thais. To account for learning effects, change in NP performance was compared to that of controls at 6 months. Analyses included multivariable regression, non-parametric repeated measures ANOVA, and Mann-Whitney U test. RESULTS Baseline NP scores for the AHI group were within normal range (Z scores range: −0.26 to −0.13). NP performance improved on CT1, CT2, and TM in the initial 3 months (ps <0.01) with no significant change during the last 3 months. Only improvement in CT1 was greater than that seen in controls at 6 months (p=0.018). Participants that performed >1 standard deviation below normative means on >2 tests (n=8) exhibited higher baseline cerebrospinal fluid (CSF) HIV RNA (p=0.047) and had no improvement after cART. CONCLUSIONS Most AHI individuals had normal NP performance and early cART slightly improved their psychomotor function. However, approximately 25% had impaired NP performance which correlated with higher CSF HIV RNA, and these abnormalities were not reversed by early cART possibly indicating limited reversibility of cognitive impairment in a subset of AHI individuals.

    Objectives To describe the CD4 cell count at the start of combination antiretroviral therapy (cART) in low-income (LIC), lower middle-income (LMIC), upper middle-income (UMIC) and high-income (HIC) countries. Methods Patients aged ≥16 years starting cART in a clinic participating in a multi-cohort collaboration spanning six continents (International epidemiological Databases to Evaluate AIDS and ART Cohort Collaboration) were eligible. Multi-level linear regression models were adjusted for age, gender and calendar year; missing CD4 counts were imputed. Findings 379,865 patients from nine LIC, four LMIC, four UMIC and six HIC were included. In LIC the median CD4 cell count at cART initiation increased by 83% from 80 to 145 cells/μl between 2002 and 2009. Corresponding increases in LMIC, UMIC and HIC were from 87 to 155 cells/μl (76% increase), 88 to 135 cells/μl (53%) and 209 to 274 cells/μl (31%). In 2009, compared to LIC, median counts were 13 cells/μl (95% CI -56 to +30) lower in LMIC, 22 cells/μl (-62 to +18) lower in UMIC and 112 /μl (+75 to +149) higher in HIC. They were 23 cells/μl (95% CI +18 to +28) higher in women than men. Median counts were 88 cells/μl (95% CI +35 to +141) higher in countries with an estimated national cART coverage >80%, compared to countries with <40% coverage. Conclusions Median CD4 cell counts at start of cART increased 2000-2009 but remained below 200 cells/μl in LIC and MIC and below 300 cells/μl in HIC. Earlier start of cART will require substantial efforts and resources globally. PMID:24419071

    We describe an HIV-infected patient initiated on combined antiretroviral therapy (cART) who subsequently developed immune restoration disease (IRD) hyperthyroidism-this case represents one of five such patients seen at our center within the past year. Similar to previous reports of hyperthyroidism due to IRD, all of our patients experienced a rapid early recovery in total CD4 count, but developed symptoms of hyperthyroidism on average 3 years (38 months) after beginning cART, which represents a longer time frame than previously reported. Awareness and recognition of this potential complication of cART, which may occur years after treatment initiation, will allow patients with immune restorative hyperthyroidism to receive timely therapy and avoid the long-term complications associated with undiagnosed thyroid disease.

    Objective: Few data describe antiretroviral treatment (ART)-related adverse events when treatment is initiated at CD4+ cell counts more than 350 cells/μl. We compared rates of laboratory-defined adverse events (LDAEs) according to CD4+ cell count at ART initiation. Design: Analysis of on-going cohort study. Methods: ART-naive persons initiating ART from 2000 to 2010 were included. Chi-square, analysis of variance (ANOVA) and Kruskal–Wallis tests compared characteristics among those starting ART with a CD4+ cell count of 350 or less, 351–499 and at least 500 cells/μl. Time-updated Poisson regression compared rates of LDAE in the three CD4+ cell strata. Cox proportional hazard models compared risk of ART discontinuation. Results: Nine thousand, four hundred and six individuals were included: median age 37 years, 61% white, 80% men, median viral load 4.8 log copies/ml. Four hundred and forty-seven (4.9%) and 1099 (11.7%) started ART with a CD4+ cell count at least 500 and 351–499 cells/μl, respectively. One thousand, two hundred and eighty-three (13.6%) patients experienced at least one LDAE. The rate of LDAE did not differ between those starting ART with a CD4+ cell count 351–499 and less than 350 cells/μl [relative rate 0.90, 95% confidence interval (CI) 0.74–1.09)], but an increased risk of ART discontinuation was observed (hazard ratio 1.58, 95% CI 1.10–2.27). Those starting ART at CD4+ cell count at least 500 cells/μl had an increased rate of LDAE (relative rate 1.44, 95% CI 1.13–1.82) but were not more likely to discontinue ART (hazard ratio 1.15, 95% CI 0.64–2.09). Conclusion: This study demonstrates the need to consider ART-related toxicities when initiating therapy at CD4+ cell counts at least 500 cells/μl. Whilst evidence from randomized controlled trials is awaited, the timing of ART initiation in terms of benefits and risks of ART remains an important question. PMID:24583670

    In 2003, the Chinese Government initiated a free antiretroviral therapy (ART) program focusing on adult AIDS patients. Pediatric antiretroviral (ARV) formulations were yet unavailable. It was not until July 2005, with the initiation of a two-stage program implemented by the Chinese Ministry of Health, that pediatric formulations became accessible in China. Initially, the pediatric ART program was piloted in six provinces with the highest incidences of pediatric HIV/AIDS. The pilot stage allowed the Chinese Center for Disease Control and Prevention (CCDC) to finalize entry criteria, treatment regimen, and patient monitoring and follow-up procedures. The second stage commenced at the end of 2006 when the program was scaled-up nationally. In order to guarantee treatment of pediatric patients, extensive training in the selection of appropriate ARV drug regimen and dosage was provided to doctors, often through on-site collaboration with domestic and international experts. The CCDC simultaneously established a pediatric ARV management system and a pediatric ART information system. CD4 count and other laboratory tests are being routinely performed on these pediatric patients. By the end of June 2009, 1529 pediatric patients had received ARV under the national program. However, challenges remain. Firstly, many children infected with HIV/AIDS live in rural areas where the treatment quality is hindered by the limited number of medical facilities and skilled medical workers. Secondly, much of the pediatric ARV drug supply depends on donation. An effort needs to be made by the Chinese Government to establish China's own drug procurement and supply system. PMID:20665285

    Ethnopharmacological relevance A substantial proportion of the population in Papua New Guinea (PNG) lives with human immunodeficiency virus (HIV). Treatment requires lifelong use of antiretroviral therapy (ART). The majority of people in PNG use traditional medicines (TM) derived from plants for all types of health promotions. Consequently, there is a concern that herb-drug interactions may impact the efficacy of ART. Herb-drug, or drug-drug, interactions occur at the level of metabolism through two major mechanisms: enzyme induction or enzyme inhibition. In this study, extracts of commonly-used medicinal plants from PNG were screened for herb-drug interactions related to cytochrome P450s (CYPs). Materials and Methods Sixty nine methanol extracts of TM plants were screened for their ability to induce CYPs by human aryl hydrocarbon receptor- (hAhR-) and human pregnane X receptor- (hPXR-) dependent mechanisms, utilizing a commercially available cell-based luciferase reporter system. Inhibition of three major CYPs, CYP1A2, CYP3A4, and CYP2D6, was determined using human liver microsomes and enzyme-selective model substrates. Results Almost one third of the TM plant extracts induced the hAhR-dependent expression of CYP1A2, the hPXR-dependent expression of CYP3A4, or both. Almost two thirds inhibited CYP1A2, CYP3A4, or CYP2D6, or combinations thereof. Many plant extracts exhibited both induction and inhibition properties. Conclusions We demonstrated that the potent and selective ability of extracts from PNG medicinal plants to affect drug metabolizing enzymes through induction and/or inhibition is a common phenomenon. Use of traditional medicines concomitantly with ART could dramatically alter the concentrations of antiretroviral drugs in the body; and their efficacy. PNG healthcare providers should counsel HIV patients because of this consequence. PMID:25138353

    Introduction Antiretroviral therapy (ART) in resource-limited settings has expanded in the last decade, reaching >8 million individuals and reducing AIDS mortality and morbidity. Continued success of ART programs will require understanding the emergence of HIV drug resistance patterns among individuals in whom treatment has failed and managing ART from both an individual and public health perspective. We review data on the emergence of HIV drug resistance among individuals in whom first-line therapy has failed and clinical and resistance outcomes of those receiving second-line therapy in resource-limited settings. Results Resistance surveys among patients initiating first-line nonnucleoside reverse-transcriptase inhibitor (NNRTI)–based therapy suggest that 76%–90% of living patients achieve HIV RNA suppression by 12 months after ART initiation. Among patients with detectable HIV RNA at 12 months, HIV drug resistance, primarily due to M184V and NNRTI mutations, has been identified in 60%–72%, although the antiretroviral activity of proposed second-line regimens has been preserved. Complex mutation patterns, including thymidine-analog mutations, K65R, and multinucleoside mutations, are prevalent among cases of treatment failure identified by clinical or immunologic methods. Approximately 22% of patients receiving second-line therapy do not achieve HIV RNA suppression by 6 months, with poor adherence, rather than HIV drug resistance, driving most failures. Major protease inhibitor resistance at the time of second-line failure ranges from 0% to 50%, but studies are limited. Conclusions Resistance of HIV to first-line therapy is predictable at 12 months when evaluated by means of HIV RNA monitoring and, when detected, largely preserves second-line therapy options. Optimizing adherence, performing resistance surveillance, and improving treatment monitoring are critical for long-term prevention of drug resistance. PMID:23687289

    We retrospectively examined the timing of antiretroviral therapy (ART) initiation and CD4(+) T-cell recovery over 36 months among recent human immunodeficiency virus (HIV) infections using BED (HIV-1 subtypes B, E and D) immunoglobulin G capture enzyme immunoassay (BED-CEIA). Regardless of baseline CD4(+) counts, individuals (n = 393) who initiated ART >2 months after diagnosis had significantly decreased probability and rate of achieving CD4(+) counts ≥900 cells/μL or ≥600 cells/μL than those individuals (n = 135) who started ART earlier (≤2 months). But the mean CD4(+) counts in two groups converged after 30 months of treatment. Early ART initiation leads to accelerated CD4(+) recovery, but does not offer a long-term advantage in CD4(+) counts.

    Background Diagnosing hepatic injury in HIV infection can be a herculean task for clinicians as several factors may be involved. In this study, we sought to determine the effects of antiretroviral therapy (ART) and disease progression on hepatic enzymes in HIV patients. Methods A case-control study conducted from January to May 2014 at the Akwatia Government Hospital, Eastern region, Ghana, The study included 209 HIV patients on ART (designated HIV-ART) and 132 ART-naive HIV patients (designated HIV-Controls). Data gathered included demography, clinical history and results of blood tests for hepatic enzymes. We employed the Fisher’s, Chi-square, unpaired t-test and Pearson’s correlation in analysis, using GraphPad Prism and SPSS. A P value < 0.05 was considered significant. Results Median CD4 lymphocyte count of HIV-ART participants (604.00 cells/mm3) was higher than that of HIV-Controls (491.50 cells/mm3; P = 0.0005). Mean values of ALP, ALT, AST and GGT did not differ between the two groups compared (P > 0.05). There was a significant positive correlation between hepatic enzymes (ALP, ALT, AST and GGT) for both groups (p < 0.01 each). Duration of ART correlated positively with ALT (p < 0.05). The effect size of disease progression on hepatic enzymes for both groups was small. Conclusion Antiretroviral therapy amongst this population has minimal effects on hepatic enzymes and does not suggest modifications in therapy. Hepatic injury may occur in HIV, even in the absence of ART and other traditional factors. Monitoring of hepatic enzymes is still important in HIV patients. PMID:26247879

    In light of limited data on structural determinants of access and retention in antiretroviral therapy (ART) among sex workers, we examined structural correlates of ART use among sex workers living with HIV over time. Longitudinal data were drawn from a cohort of 646 female sex workers in Vancouver, Canada (2010-2012) and linked pharmacy records on ART dispensation. We used logistic regression with generalized estimating equations (GEE) to examine correlates of gaps in ART use (i.e., treatment interruptions or delayed ART initiation), among HIV seropositive participants (n = 74). Over a 2.5-year period, 37.8 % of participants experienced gaps in ART use (i.e., no ART dispensed in a 6-month period). In a multivariable GEE model, younger age, migration/mobility, incarceration, and non-injection drug use independently correlated with gaps in ART use. In spite of successes scaling-up ART in British Columbia, younger, mobile, or incarcerated sex workers face persistent gaps in access and retention irrespective of drug use. Community-based, tailored interventions to scale-up entry and retention in ART for sex workers should be further explored in this setting. PMID:26148850

    Setting: A non-governmental organisation-supported clinic offering health services including antiretroviral therapy (ART). Objective: To compare ART retention between younger (age 10–14 years) vs. older (age 15–19 years) adolescents and younger (age 20–29 years) vs. older (age ⩾30 years) adults and determine adolescent- and adult-specific attrition-associated factors among those initiated on ART between 2010 and 2011. Design: Retrospective cohort study. Results: Of 110 (7%) adolescents and 1484 (93%) adults included in the study, no differences in retention were observed between younger vs. older adolescents at 6, 12 and 24 months. More younger adolescents were initiated with body mass index <16 kg/m2 compared with older adolescents (64% vs. 47%; P = 0.04). There were more females (74% vs. 52%, P < 0.001) and fewer patients initiating ART with CD4 count ⩽350 cells/mm3 (77% vs. 81%, P = 0.007) among younger vs. older adults. Younger adults demonstrated more attrition than older adults at all time-points. No attrition risk factors were observed among adolescents. Attrition-associated factors among adults included being younger, having a lower CD4 count and advanced human immunodeficiency virus disease at initiation, and initiation on a stavudine-based regimen. Conclusion: Younger adults demonstrated greater attrition and may require more attention. We were unable to demonstrate differences in attrition among younger vs. older adolescents. Loss to follow-up was the main reason for attrition across all age groups. Overall, earlier presentation for ART care appears important for improved ART retention among adults. PMID:27358802

    The health of people living with HIV (PLWH) and the sustained success of antiretroviral therapy (ART) programmes depends on PLWH's motivation and ability to self-manage the condition over the long term, including adherence to drugs on a daily basis. PLWH's self-management of HIV and their wellbeing are likely to be interrelated. Successful self-management sustains wellbeing, and wellbeing is likely to motivate continued self-management. Detailed research is lacking on PLWH's self-management processes on ART in resource-limited settings. This paper presents findings from a study of PLWH's self-management and wellbeing in Wakiso District, Uganda. Thirty-eight PLWH (20 women, 18 men) were purposefully selected at ART facilities run by the government and by The AIDS Support Organisation in and around Entebbe. Two in-depth interviews were completed with each participant over three or four visits. Many were struggling economically, however the recovery of health and hope on ART had enhanced wellbeing and motivated self-management. The majority were managing their condition well across three broad domains of self-management. First, they had mobilised resources, notably through good relationships with health workers. Advice and counselling had helped them to reconceptualise their condition and situation more positively and see hope for the future, motivating their work to self-manage. Many had also developed a new network of support through contacts they had developed at the ART clinic. Second, they had acquired knowledge and skills to manage their health, a useful framework to manage their condition and to live their life. Third, participants were psychologically adjusting to their condition and their new 'self': they saw HIV as a normal disease, were coping with stigma and had regained self-esteem, and were finding meaning in life. Our study demonstrates the centrality of social relationships and other non-medical aspects of wellbeing for self-management which ART

    Purpose About one in five men living with HIV in the USA passes through a correctional center annually. Jails and prisons are seen therefore as key intervention sites to promote HIV treatment as prevention. Almost no research, however, has examined inmates' perspectives on HIV treatment or their strategies for retaining access to antiretroviral therapy (ART) during incarceration. The purpose of this paper is to describe the results of an exploratory study examining men's perceptions of and experiences with HIV care and ART during incarceration. Design/methodology/approach Semi-structured, in-depth interviews were conducted with 42 HIV positive male and male-to-female transgendered persons recently released from male correctional centers in Illinois, USA. Findings Interpersonal violence, a lack of safety, and perceived threats to privacy were frequently cited barriers to one's willingness and ability to access and adhere to treatment. Over 60 percent of study participants reported missed doses or sustained treatment interruption (greater than two weeks) because of failure to disclose their HIV status, delayed prescribing, intermittent dosing and out-of-stock medications, confiscation of medications, and medication strikes. Research limitations/implications Substantial improvements in ART access and adherence are likely to follow organizational changes that make incarcerated men feel safer, facilitate HIV status disclosure, and better protect the confidentiality of inmates receiving ART. Originality/value This study identified novel causes of ART non-adherence among prisoners and provides first-hand information about how violence, stigma, and the pursuit of social support influence prisoner's decisions to disclose their HIV status or accept ART during incarceration.

    Objective: To assess the adherence to antiretroviral therapy (ART) in the human immunodeficiency virus (HIV)-infected population in India. Design: Systematic review and meta-analysis. Materials and Methods: The Medline and Cochrane library database were searched. Any prospective or retrospective study enrolling a minimum of 10 subjects with a primary objective of assessing ART adherence in the HIV population in India was included. Data were extracted on adherence definition, adherence estimates, study design, study population characteristics, recall period and assessment method. For metaanalysis, the pooled proportion was calculated as a back-transform of the weighted mean of the transformed proportions (calculated according to the Freeman-Tukey variant of the arcsine square root) using the random effects model. Results: There were seven cross-sectional studies and one retrospective study enrolling 1666 participants. Publication bias was significant (P = 0.003). Pooled results showed an ART adherence rate of 70% (95% confidence interval: 59–81%, I2 = 96.3%). Sensitivity analyses based on study design, adherence assessment method and study region did not influence adherence estimates. Fifty percent (4/8) of the studies reported cost of medication as the most common obstacle for ART adherence. Twenty-five percent (2/8) reported lack of access to medication as the reason for non-adherence and 12% (1/8) cited adverse events as the most prevalent reason for non-adherence. The overall methodological quality of the included studies was poor. Conclusion: Pooled results show that overall ART adherence in India is below the required levels to have an optimal treatment effect. The quality of studies is poor and cannot be used to guide policies to improve ART adherence. PMID:23878418

    Treating HIV-infected patients with a combination of several antiretroviral drugs can lead to emergence of the drug-resistant strain. This work proposes a mathematical model to evaluate the emergence of HIV-1 drug resistant during antiretroviral therapy. The model assumes that all susceptible individuals who can be infected by the wildtype strain (sensible to the treatment) or by drug-resistant virus receive antiretroviral therapy. Patients on treatment regimen can evolve to a state of success or failure and for the individuals in therapeutic fail the therapeutic schema is changed. The analysis of system is performed. The existence and stability of the steady states are considered. We address an analytical expression for the reproductive number in a community where antiretroviral therapy are widely used to treat HIV and where both drug sensitive and drug resistant strains are co-circulating.

    Antiretroviral drugs have saved and extended the lives of millions of individuals infected with HIV. The major classes of anti-HIV drugs include reverse transcriptase inhibitors, protease inhibitors, integrase inhibitors, and entry/fusion inhibitors. While antiretroviral drug regimens are not commonly used to treat other types of retroviral infections, there are instances where there is a perceived need for re-evaluation of the benefits of antiretroviral therapy. One case in point is that of feline leukemia virus (FeLV), an infection of companion felines. While vaccines exist to prevent FeLV infection and spread, they have not eliminated FeLV infection. For FeLV-infected felines and their human companions, antiretroviral therapy would be desirable and of practical importance if good options were available. Here, we discuss FeLV biology and current treatment options, and propose that there is a need for antiretroviral treatment options for FeLV infection. The comparative use and analysis of antiretroviral therapy can provide new insights into the mechanism of antiretroviral drug action. PMID:21479142

    Health behaviors, such as retention in HIV medical care and adherence to antiretroviral therapy (ART), pose major challenges to reducing new HIV infections, addressing health disparities, and improving health outcomes. Andersen's Behavioral Model of Health Service Use provides a conceptual framework for understanding how patient and environmental factors affect health behaviors and outcomes, which can inform the design of intervention strategies. Factors affecting retention and adherence among persons with HIV include patient predisposing factors (e.g. mental illness, substance abuse), patient enabling factors (e.g. social support, reminder strategies, medication characteristics, transportation, housing, insurance), and health care environment factors (e.g. pharmacy services, clinic experiences, provider characteristics). Evidence-based recommendations for improving retention and adherence include 1) systematic monitoring of clinic attendance and ART adherence; 2) use of peer or paraprofessional navigators to re-engage patients in care and help them remain in care; 3) optimization of ART regimens and pharmaceutical supply chain management systems 4) provision of reminder devices and tools; 5) general education and counseling; 6) engagement of peer, family, and community support groups; 7) case management; and 8) targeting patients with substance abuse and mental illness. Further research is needed on effective monitoring strategies and interventions that focus on improving retention and adherence, with specific attention to the health care environment. PMID:25792300

    The discovery of the human immunodeficiency virus (HIV) as the causative organism of acquired immunodeficiency syndrome (AIDS) and the inability of modern medicine to find a cure for it has placed HIV as one of the most dreaded pathogens of the 21st century. With millions of people infected with HIV, it was once thought to result in “medical apocalypse”. However, with the advent of antiretroviral therapy (ART), it is now possible to control HIV. Adherence to ART helps to keep the viral load under control and prolong the time of progression to AIDS, resulting in near normal life expectancy. Even with the introduction of ART, a substantial number of patients fail to adhere due to a variety of reasons, including adverse side effects, drug abuse, mental disorders, socioeconomic status, literacy, and social stigma. With the availability of so many options for HIV treatment at each stage of the disease progression, physicians can switch between the treatment regimens to avoid and/or minimize the adverse effects of drugs. Close monitoring, major social reforms, and adequate counselling should also be implemented to circumvent other challenges.

    Panic symptoms are prevalent among PLWHAs, yet few studies have examined their relationship with HIV outcomes. Using data from an observational cohort study in Baltimore, MD, we examined the association between panic symptoms and antiretroviral therapy (ART) use, medication adherence, and viral suppression. Data were analyzed using generalized estimating equations and adjusted for age, sex, race/ethnicity, cocaine and/or heroin use, clinic enrollment time, alcohol use, and depressive symptoms. Between June 2010 and September 2012, 1195 individuals participated in 2080 audio computer assisted interviews; 9.9 % (n = 118) of individuals endorsed current panic symptoms. In multivariate analysis, panic symptoms were associated with decreased ART use (IRR 0.94; p = 0.05). Panic symptoms were neither associated with medication adherence nor viral suppression. These findings were independent of depressive symptoms and substance use. Panic symptoms are under-recognized in primary care settings and present an important barrier to ART use. Further studies investigating the reasons for this association are needed. PMID:25903506

    HIV transmission is still a public health concern in sub-Saharan Africa; disclosure is an effective tool for its prevention, contact tracing and treatment. We aimed to evaluate the disclosure behaviours of adult HIV-positive patients receiving antiretroviral therapy (ART) in University of Port Harcourt Teaching Hospital, and identify major challenges to disclosure in a bid to develop ways to improve this practice in the environment. Patients receiving ART in this centre were interviewed using an interviewer-administered questionnaire. A total of 250 clients were interviewed over three months. A majority of the patients were tested on account of ill health 143 (57.2%). They commenced ART within 8 ± 15.4 SD months of presentation. The mean period before disclosure was 4.75 ± 12.8 SD months of diagnosis. Thirty-six (14.4%) of the respondents had not disclosed their HIV status; the major barrier to disclosure was stigmatisation in 19 (36%). PMID:25249594

    Introduction Lipodystrophy is a frequent and disfiguring adverse effect of antiretroviral therapy (ART) in patients with HIV. It affects the quality of life of the patient and adherence to treatment, and generates new needs for comprehensive healthcare services. The aim of this study will be to conduct a systematic review of the literature from observational studies and describe lipodystrophy among patients with HIV infection during current or previous use of ART. Methods and analysis A systematic review of observational studies published in MEDLINE, CINAHL, LILACS, EMBASE and International Pharmaceutical Abstracts will be carried out. Citations of included studies will be checked to identify additional studies not identified in the electronic searches. It will include any observational study that considered lipodystrophy as the primary or secondary outcome and that had enrolled adolescent and adult patients with HIV infection who were on current or previous ART for at least 6 months. Data extraction and analysis will be performed independently by two reviewers. The extracted data will be discussed, decisions documented and, where necessary, the authors of the studies will be contacted for clarification. Measures of frequency, prevalence and incidence of lipodystrophy will be stratified according to definition, method of diagnosis and risk factors of the outcome. Ethics and dissemination Ethics is not required given this is a protocol for a systematic review. The findings of this study will be widely disseminated through peer-reviewed publications and conference presentations. Updates of the review will be conducted to inform and guide healthcare practice. Protocol registration PROSPERO—42013005450. PMID:24625638

    More than 3 million people were receiving antiretroviral therapy (ART) at the end of 2007, but this number represents only 31% of people clinically eligible for ART in resource-limited settings. The primary objective of this study is to summarize the key obstacles that impede the goal of universal access prevention, care, and treatment. We performed a systematic literature search to review studies that reported barriers to diagnosis and access to treatment of HIV/AIDS in resource-limited countries. Persons living with HIV/ AIDS commonly face economic, sociocultural, and behavioral obstacles to access treatment and care for HIV. A variety of programs to overcome these barriers have been implemented, including efforts to destigmatize HIV/AIDS, enhance treatment literacy, provide income-generation skills, decentralize HIV services, promote gender equality, and adopt a multisectoral approach to optimize limited resources. An understanding of these obstacles and suggested methods to overcome them must be addressed by global policy makers before universal ART access can be achieved. PMID:19721103

    HIV-related stigma has been linked to avoidance of health care services and suboptimal adherence to antiretroviral therapy (ART). However, less is known about concerns of stigma related specifically to the taking of ART in uptake of treatment. This study examines experiences of HIV treatment-related stigma and assesses if these experiences are associated with ART uptake, independent of general HIV-related stigma. People living with HIV (PLHIV; n = 697) were targeted to complete an online questionnaire measuring perceived HIV- and treatment-related stigma, social support, self-esteem, resilience, psychological distress, health satisfaction and quality of life. Findings suggest that experiences of general and treatment-related stigma were common, and that participants appear to experience greater stigma related to taking HIV treatment than general stigma associated with HIV. Neither general nor treatment-related stigma uniquely impacted HIV treatment uptake. Instead, treatment uptake was associated with being older (adjusted OR 1.05; 95% CIs: 1.03, 1.08), greater duration of HIV infection (adjusted OR 1.07; 95% CIs: 1.03-1.11) and having greater health satisfaction (adjusted OR 1.28; 95% CIs: 1.03, 1.59). Findings highlight that concerns around taking HIV treatment can be an added source of stigma for PLHIV, however other factors may be greater contributors to the likelihood of taking HIV treatment.

    Central nervous system (CNS) HIV-1 infection begins during primary viremia and continues throughout the course of untreated systemic infection. While frequently accompanied by local inflammatory reactions detectable in cerebrospinal fluid (CSF), CNS HIV-1 infection is not usually clinically apparent. In a minority of patients, CNS HIV-1 infection evolves late in the course of systemic infection into encephalitis, which compromises brain function and presents clinically as AIDS dementia complex (ADC). Combination highly active antiretroviral therapy (HAART) has had a major impact on all aspects of HIV-1 CNS infection and disease. In those with asymptomatic infection, HAART usually effectively suppresses CSF HIV-1 and markedly reduces the incidence of symptomatic ADC. In those presenting with ADC, HAART characteristically prevents neurological progression and leads to variable, and at times substantial, recovery. Treatment has similarly reduced CNS opportunistic infections. With better control of these severe disorders, attention has turned to the possible consequences of chronic silent infection, and the issue of whether indolent, low-grade brain injury might require earlier treatment intervention.

    2011-01-01

    The past decade has seen remarkable progress in increasing access to antiretroviral therapy in resource-limited settings. Early concerns about the cost and complexity of treatment were overcome thanks to the efforts of a global coalition of health providers, activists, academics, and people living with HIV/AIDS, who argued that every effort must be made to ensure access to essential care when millions of lives depended on it. The high cost of treatment was reduced through advocacy to promote access to generic drugs; care provision was simplified through a public health approach to treatment provision; the lack of human resources was overcome through task-shifting to support the provision of care by non-physicians; and access was expanded through the development of models of care that could work at the primary care level. The challenge for the next decade is to further increase access to treatment and support sustained care for those on treatment, while at the same time ensuring that the package of care is continuously improved such that all patients can benefit from the latest improvements in drug development, clinical science, and public health.

    Great progress has been made in achieving universal access to antiretroviral therapy (ART). However, for successful viral suppression, patients must adhere to rigid and complex treatment regimens. With three quarters of antiretroviral (ARV) users in Africa adhering successfully, African countries have achieved extraordinary levels of adherence given the levels of poverty in which many ARV users live. Nevertheless, one quarter of ARV users still struggle to adhere and run the risk of experiencing viral replication, clinical progression or even drug resistance. Much has been written about ART adherence, but little has been done to systematically categorise the spectrum of factors that influence ART. In this paper, we use a Zimbabwean case study to develop a framework for ART programme planners and implementers seeking to identify and tackle social obstacles to adherence. We draw on interviews and group discussions with 25 nurses and 53 adult ARV users, which we analysed through a three-tiered thematic approach, allowing us to categorise our findings into broader dimensions that can transcend our case study and be applied elsewhere. Our findings suggest that ART adherence is influenced by the material, symbolic, relational and institutional contexts in which ARV users live as well as the patient's motivation, participation and psychosocial responses to ART. This framework allows us to examine both the social context in which ART programmes are located and the psychosocial factors that influence patient behaviours. We offer this framework as a resource for ART programme planners and implementers seeking to improve ART compliance in resource-poor settings. Copyright © 2011 John Wiley & Sons, Ltd. PMID:21744381

    In order to assess the effectiveness of the Chinese government's expanded access program, a cohort study on all adult HIV patients in Shenzhen was conducted from December 2003 to February 2014 to estimate the effects of antiretroviral therapy (ART) on mortality, tuberculosis and CD4 cell counts. Marginal structural regression models adjusted for baseline and time-varying covariates. Of the 6897 patients enrolled and followed up for a maximum of 178 months, 44.92% received ART. Among patients who commenced receiving ART during the study, there were 98 deaths and 59 new tuberculosis diagnoses, while there were 410 deaths and 201 new tuberculosis diagnoses among those without ART. ART was associated with both lower mortality (hazard ratio [HR] = 0.18; 95% confidence interval [CI] = 0.11-0.27) and the presence of tuberculosis (HR = 0.27; 95% CI = 0.19-0.37). Each month of ART was associated with an average increase in CD4 cell count of 6.52 cells/µL (95% CI = 6.08-7.12 cells/µL). In conclusions, the effectiveness of ART provided by China government health services is the same as that in higher-income countries. Accounting to higher mortality rates from the delay of starting ART, faster expansion and timely imitation of ART are urgent. PMID:26213959

    For children younger than five years, caregivers are responsible for the measurement and administration of antiretroviral medication doses to children. Failure to adhere to the regimen as prescribed may lead to high viral loads (VLs), immune suppression and ultimately drug resistance. In the content of this study, adherence refers to adequate dosing of the medication by a caregiver. Acquired drug resistance to antiretroviral therapy (ART) is prevalent amongst children in South Africa, and poor adherence to the dosing regimen by caregivers may be associated with this problem. In this qualitative study, we purposively recruited 33 caregiver-child dyads from the Hlabisa HIV Treatment and Care Programme database. Children were divided into three groups based on their VL at the time of recruitment. Children with a VL ≥ 400 cps/ml were grouped as unsuppressed (n = 11); children with a VL ≤ 400 cps/ml were grouped as suppressed (n = 12); and children with no VL data were grouped as newly initiated (n = 10). Caregiver-child dyads were visited at their households twice to document, by means of video recording, how treatment was administered to the child. Observational notes and video recordings were entered into ATLAS.ti v 7 and analysed thematically. Results were interpreted through the lens of Ecological Systems Theory and the information-motivation-behavioural skills model was used to understand and reflect on several of the factors influencing adherence within the child's immediate environment as identified in this study.

    2013-01-01

    The rollout of antiretroviral therapy (ART) significantly reduced human immunodeficiency virus (HIV)-related morbidity and mortality, but good clinical outcomes depend on access and adherence to treatment. In resource-limited settings, where over 90% of the world’s HIV-infected population resides, data on barriers to treatment are emerging that contribute to low rates of uptake in HIV testing, linkage to and retention in HIV care systems, and suboptimal adherence rates to therapy. A review of the literature reveals limited evidence to inform strategies to improve access and adherence with the majority of studies from sub-Saharan Africa. Data from observational studies and randomized controlled trials support home-based, mobile and antenatal care HIV testing, task-shifting from doctor-based to nurse-based and lower level provider care, and adherence support through education, counseling and mobile phone messaging services. Strategies with more limited evidence include targeted HIV testing for couples and family members of ART patients, decentralization of HIV care, including through home- and community-based ART programs, and adherence promotion through peer health workers, treatment supporters, and directly observed therapy. There is little evidence for improving access and adherence among vulnerable groups such as women, children and adolescents, and other high-risk populations and for addressing major barriers. Overall, studies are few in number and suffer from methodological issues. Recommendations for further research include health information technology, social-level factors like HIV stigma, and new research directions in cost-effectiveness, operations, and implementation. Findings from this review make a compelling case for more data to guide strategies to improve access and adherence to treatment in resource-limited settings. PMID:23326204

    There is general consistency among US and European guidelines regarding the initiation of antiretroviral therapy for HIV-infected individuals. Recent and ongoing trials comparing regimens may lead to reevaluation of initial treatment choices. The choice of antiretroviral regimen will also likely be affected by development, evaluation, and availability of newer drugs. This article reviews currently recommended regimens and characteristics of selected current investigational drugs, including the nucleotide analogue reverse transcriptase inhibitor tenofovir alafenamide, the nonnucleoside reverse transcriptase inhibitor doravirine, the integrase strand transfer inhibitor cabotegravir, the HIV entry inhibitor BMS-663068, and the HIV maturation inhibitor BMS-955176.

    OBJECTIVE: To describe the supervision, monitoring and evaluation strategies used to assess the delivery of antiretroviral therapy during nationwide scale-up of treatment in Malawi. METHODS: In the first quarter of 2005, the HIV Unit of the Ministry of Health and its partners (the Lighthouse Clinic; Médecins Sans Frontières-Belgium, Thyolo district; and WHO's Country Office) undertook structured supervision and monitoring of all public sector health facilities in Malawi delivering antiretroviral therapy. FINDINGS: Data monitoring showed that by the end of 2004, there were 13,183 patients (5274 (40%) male, 12 527 (95%) adults) who had ever started antiretroviral therapy. Of patients who had ever started, 82% (10 761/13,183) were alive and taking antiretrovirals; 8% (1026/13,183) were dead; 8% (1039/13,183) had been lost to follow up; <1% (106/13,183) had stopped treatment; and 2% (251/13,183) had transferred to another facility. Of those alive and on antiretrovirals, 98% (7098/7258) were ambulatory; 85% (6174/7258) were fit to work; 10% (456/4687) had significant side effects; and, based on pill counts, 96% (6824/7114) had taken their treatment correctly. Mistakes in the registration and monitoring of patients were identified and corrected. Drug stocks were checked, and one potential drug stock-out was averted. As a result of the supervisory visits, by the end of March 2005 recruitment of patients to facilities scheduled to start delivering antiretroviral therapy had increased. CONCLUSION: This report demonstrates the importance of early supervision for sites that are starting to deliver antiretroviral therapy, and it shows the value of combining data collection with supervision. Making regular supervisory and monitoring visits to delivery sites are essential for tracking the national scale-up of delivery of antiretrovirals. PMID:16628306

    Background: Despite significant efforts to understand adverse pregnancy outcome in women receiving Antiretroviral Therapy (ART), ART-related adverse birth outcomes are still poorly understood. We systematically review ART-related adverse birth outcomes among HIV-infected pregnant women; we also review the covariates associated with adverse birth outcomes in the aforementioned group. Methods: The main source for our systematic review was electronic bibliographic databases. Databases such as MEDLINE, PubMed, EMBASE and AIDSLINE were searched. Furthermore, search engines such as Google and Google Scholar were specifically searched for gray literature. Methodological quality of available literature was assessed using the Newcastle - Ottawa Quality Assessment Scale & M. Hewitt guideline. We examined a total of 1,124 papers and reviewed the studies using the PICOT criteria which stands for Patient (population), Intervention (or “Exposure”), Comparison, Outcome and Type of study. Finally, 32 methodologically fit studies were retained and included in our review. Results: Frequently observed adverse birth outcomes included low birth weight (LBW), Preterm Birth (PB), Small for Gestational Age (SGA), while still birth and congenital anomalies were infrequent. Type of regimen such as Protease Inhibitor (PI) based regimens and timing of initiation of ART are some of the factors associated with adverse pregnancy outcomes. Covariates principally included malnutrition and other co-morbidities such as malaria and HIV. Conclusions and Public Health Implications: There is growing evidence in published literature suggesting that ART might be causing adverse birth outcomes among pregnant women in developing countries. There is a need to consider regimen types for HIV-infected pregnant women. There is need to design large cohort studies.

    After 30 years we are still struggling to address a devastating HIV pandemic in which over 25 million people have died. In 2010, an estimated 34 million people were living with HIV, around 70% of whom live in sub-Saharan Africa. Furthermore, in 2009 there were an estimated 1.2 million new HIV-associated TB cases, and tuberculosis (TB) accounted for 24% of HIV-related deaths. By the end of 2010, 6.6 million people were taking antiretroviral therapy (ART), around 42% of those in need as defined by the 2010 World Health Organization (WHO) guidelines. Despite this achievement, around 9 million people were eligible and still in need of treatment, and new infections (approximately 2.6 million in 2010 alone) continue to add to the future caseload. This combined with the international fiscal crisis has led to a growing concern regarding weakening of the international commitment to universal access and delivery of the Millennium Development Goals by 2015. The recently launched UNAIDS/WHO Treatment 2.0 platform calls for accelerated simplification of ART, in line with a public health approach, to achieve and sustain universal access to ART, including maximizing the HIV and TB preventive benefit of ART by treating people earlier, in line with WHO 2010 normative guidance. The potential individual and public health prevention benefits of using treatment in the prevention of HIV and TB enhance the value of the universal access pledge from a life-saving initiative, to a strategic investment aimed at ending the HIV epidemic. This review analyzes the gaps and summarizes the evidence regarding ART in the prevention of HIV and TB. PMID:21999771

  7. A prospective study of vaginal trichomoniasis and HIV-1 shedding in women on antiretroviral therapy

    Background Trichomonas vaginalis has been associated with increased vaginal HIV-1 RNA shedding in antiretroviral therapy (ART)-naïve women. The effect of trichomoniasis on vaginal HIV-1 shedding in ART-treated women has not been characterized. We tested the hypothesis that T. vaginalis infection would increase vaginal HIV-1 RNA shedding in women on ART, and that successful treatment would reduce vaginal HIV-1 RNA levels. Methods We conducted a prospective cohort study including monthly follow-up of 147 women receiving ART in Mombasa, Kenya. Those with T. vaginalis infection, defined by the presence of motile trichomonads on vaginal saline wet mount, received treatment with single dose metronidazole (2 g). Test of cure was performed at the next monthly visit. Using the pre-infection visit as the reference category, we compared detection of vaginal HIV-1 RNA before versus during and after infection using generalized estimating equations. A cut-off of 100 HIV-1 RNA copies/swab was used as the lower limit for linear quantitation. Results Among 31 women treated for trichomoniasis, the concentration of vaginal HIV-1 RNA was above the limit for quantitation before, during, and after T. vaginalis infection in 4 (13% [95% CI 4% - 30%]), 4 (13% [95% CI 4% - 30%]), and 5 (16% [95% confidence interval {CI} 5% - 34%]) women respectively. After adjusting for potential confounding factors, we could detect no difference in the likelihood of detecting vaginal HIV-1 RNA before versus during infection (odds ratio [OR] 1.41, 95% CI 0.23 - 8.79, p = 0.7). In addition, detection of HIV-1 RNA was similar before infection versus after successful treatment (OR 0.68, 95% CI (0.13 - 3.45), p = 0.6). Conclusion Detection of vaginal HIV-1 RNA during ART was uncommon at visits before, during and after T. vaginalis infection. PMID:22047086

    For optimal health, people living with HIV (PLWH) need to adhere to antiretroviral therapy (ART). We explored the relationship between symptoms of depression and ART adherence for PLWH born inside versus outside of Canada. PLWH taking ART (N = 57) completed self-assessments of depression and adherence to ART. Adherence rates did not differ significantly for PLWH who were born outside (66.7% were ≥95% adherent) versus inside Canada (51.6% were ≥95% adherent), but the relationship between symptoms of depression and ART adherence depended on the country of birth: for individuals born in Canada, depression was associated with lower ART adherence (β = -.21, p = .005, 95% confidence interval -.35 to -.07); for PLWH born outside of Canada there was no association between symptoms of depression and ART adherence. Symptoms of depression may not universally affect ART adherence; country of birth may be one critical variable impacting this relationship. PMID:26987784

    Abstract A number of cellular microRNAs (miRNAs) have been identified to have the ability to inhibit HIV-1 replication. In this study, we examined the impact of combination antiretroviral therapy (cART) on the expression of HIV-1 restriction miRNAs in peripheral blood mononuclear cells of HIV-1–infected men who have sex with men (MSM). Compared with male healthy donors, HIV-infected MSM had significantly lower levels of 9 HIV-1 restriction miRNAs. The treatment of HIV-1–infected MSM with cART, however, failed to restore the levels of these miRNAs in peripheral blood mononuclear cells. These observations suggest that the suppression of the cellular restriction miRNAs by HIV-1 may attribute to the virus latency during cART. PMID:26579828

    Introduction Recent WHO guidance advocates for early antiretroviral therapy (ART) initiation at higher CD4 counts to improve survival and reduce HIV transmission. We sought to quantify how the cost-effectiveness and epidemiological impact of early ART strategies in India are affected by attrition throughout the HIV care continuum. Methods We constructed a dynamic compartmental model replicating HIV transmission, disease progression and health system engagement among Indian adults. Our model of the Indian HIV epidemic compared implementation of early ART initiation (i.e. initiation above CD4 ≥350 cells/mm3) with delayed initiation at CD4 ≤350 cells/mm3; primary outcomes were incident cases, deaths, quality-adjusted-life-years (QALYs) and costs over 20 years. We assessed how costs and effects of early ART initiation were impacted by suboptimal engagement at each stage in the HIV care continuum. Results Assuming “idealistic” engagement in HIV care, early ART initiation is highly cost-effective ($442/QALY-gained) compared to delayed initiation at CD4 ≤350 cells/mm3 and could reduce new HIV infections to <15,000 per year within 20 years. However, when accounting for realistic gaps in care, early ART initiation loses nearly half of potential epidemiological benefits and is less cost-effective ($530/QALY-gained). We project 1,285,000 new HIV infections and 973,000 AIDS-related deaths with deferred ART initiation with current levels of care-engagement in India. Early ART initiation in this continuum resulted in 1,050,000 new HIV infections and 883,000 AIDS-related deaths, or 18% and 9% reductions (respectively), compared to current guidelines. Strengthening HIV screening increases benefits of earlier treatment modestly (1,001,000 new infections; 22% reduction), while improving retention in care has a larger modulatory impact (676,000 new infections; 47% reduction). Conclusions Early ART initiation is highly cost-effective in India but only has modest

    We examined current challenges with patient engagement in HIV prevention and care in South Africa by assessing the procedures of eight public health clinics in the North West Province. Procedures consisted of (1) an inventory/audit of the HIV Counseling and Testing, pre-antiretroviral therapy (pre-ART), and antiretroviral therapy (ART) patient registers; (2) extraction of data from a convenience sample of 39 HIV-positive patient files; and (3) 13 key informant interviews with clinic staff to characterize retention and re-engagement practices for patients. Incomplete registers revealed little evidence of follow-up services, particularly for pre-ART patients. The more detailed examination of patient files indicated substantial disparities in the proportion of pre-ART versus ART patients retained in care. Key informant interviews contextualized the data, with providers describing multiple procedures for tracking and ensuring service delivery for ART patients and fewer procedures to retain pre-ART patients. These findings suggest that enhanced strategies are needed for ensuring continued engagement in HIV care, with a particular emphasis on improving the retention of pre-ART patients. The preventive benefits of ART scale-up may not be achieved if improvements are not made in the proportion of earlier-stage HIV-positive patients who are successfully engaged in care. PMID:26278130

    ABSTRACT A major goal in HIV eradication research is characterizing the reservoir cells that harbor HIV in the presence of antiretroviral therapy (ART), which reseed viremia after treatment is stopped. In general, it is assumed that the reservoir consists of CD4+ T cells that express no viral proteins. However, recent findings suggest that this may be an overly simplistic view and that the cells that contribute to the reservoir may be a diverse population that includes both CD4+ and CD4− cells. In this study, we directly infected resting CD4+ T cells and used fluorescence-activated cell sorting (FACS) and fiber-optic array scanning technology (FAST) to identify and image cells expressing HIV Gag. We found that Gag expression from integrated proviruses occurred in resting cells that lacked surface CD4, likely resulting from Nef- and Env-mediated receptor internalization. We also extended our approach to detect cells expressing HIV proteins in patients suppressed on ART. We found evidence that rare Gag+ cells persist during ART and that these cells are often negative for CD4. We propose that these double-negative α/β T cells that express HIV protein may be a component of the long-lived reservoir. IMPORTANCE A reservoir of infected cells persists in HIV-infected patients during antiretroviral therapy (ART) that leads to rebound of virus if treatment is stopped. In this study, we used flow cytometry and cell imaging to characterize protein expression in HIV-infected resting cells. HIV Gag protein can be directly detected in infected resting cells and occurs with simultaneous loss of CD4, consistent with the expression of additional viral proteins, such as Env and Nef. Gag+ CD4− cells can also be detected in suppressed patients, suggesting that a subset of infected cells express proteins during ART. Understanding the regulation of viral protein expression during ART will be key to designing effective strategies to eradicate HIV reservoirs. PMID:26537682

    Introduction There is a risk of anaemia among HIV-infected children on antiretroviral therapy (ART) containing zidovudine (ZDV) recommended in first-line regimens in the WHO guidelines. We estimated the risk of severe anaemia after initiation of a ZDV-containing regimen in HIV-infected children included in the IeDEA West African database. Methods Standardized collection of data from HIV-infected children (positive PCR<18 months or positive serology ≥18 months) followed up in HIV programmes was included in the regional IeDEA West Africa collaboration. Ten clinical centres from seven countries contributed (Benin, Burkina Faso, Côte d'Ivoire, Gambia, Ghana, Mali and Senegal) to this collection. Inclusion criteria were age <16 years and starting ART. We explored the data quality of haemoglobin documentation over time and the incidence and predictors of severe anaemia (Hb<7g/dL) per 100 child-years of follow-up over the duration of first-line antiretroviral therapy. Results As of December 2009, among the 2933 children included in the collaboration, 45% were girls, median age was five years; median CD4 cell percentage was 13%; median weight-for-age z-score was −2.7; and 1772 (60.4%) had a first-line ZDV-containing regimen. At baseline, 70% of the children with a first-line ZDV-containing regimen had a haemoglobin measure available versus 76% in those not on ZDV (p≤0.01): the prevalence of severe anaemia was 3.0% (n=38) in the ZDV group versus 10.2% (n=89) in those without (p<0. 01). Over the first-line follow-up, 58.9% of the children had ≥1 measure of haemoglobin available in those exposed to ZDV versus 60.4% of those not (p=0.45). Severe anaemia occurred in 92 children with an incidence of 2.47 per 100 child-years of follow-up in those on a ZDV-containing regimen versus 4.25 in those not (p≤0.01). Adjusted for age at ART initiation and first-line regimen, a weight-for-age z-score ≤−3 was a strong predictor associated with a 5.59 times risk of severe

    Objective To inform guidelines concerning when to initiate combination antiretroviral therapy (ART), we investigated whether CD4+ T-cell counts (CD4 counts) continue to increase over long periods of time on ART. Losses-to-follow-up and some patients discontinuing ART at higher CD4 counts hamper such evaluation, but novel statistical methods can help address these issues. We estimated the long-term CD4 count trajectory accounting for losses-to-follow-up and treatment discontinuations. Design The study population included 898 U.S. patients first initiating ART in a randomized trial (ACTG 384); 575 were subsequently prospectively followed in an observational study (ALLRT). Methods Inverse probability of censoring weighting statistical methods were used to estimate the CD4 count trajectory accounting for losses-to-follow-up and ART-discontinuations, overall and for pre-treatment CD4 count categories ≤ 200, 201–350, 351–500, and >500 cells/mm3. Results Median CD4 count increased from 270 cells/mm3 pre-ART to an estimated 556 at three and 532 cells/mm3 at seven years after starting ART in analyses ignoring treatment discontinuations; and to 570 and 640 cells/mm3, respectively, had all patients continued ART. However, even had ART been continued, an estimated 25%, 9%, 3% and 2% of patients with pre-treatment CD4 counts of ≤ 200, 201–350, 351–500, and >500 cells/mm3 would have had CD4 counts ≤350 cells/mm3 after seven years. Conclusions If patients remain on ART, CD4 counts increase in most patients for at least seven years. However, the substantial percentage of patients starting therapy at low CD4 counts who still had low CD4 counts after seven years provides support for ART initiation at higher CD4 counts.

    The number of people receiving antiretroviral treatment (ART) has increased considerably in recent years and is expected to continue to grow in the coming years. A major challenge is to maintain uninterrupted supplies of antiretroviral (ARV) drugs and prevent stock outs. This article discusses issues around the management of ARVs and prevention of stock outs in Malawi, a low-income country with a high HIV/AIDS burden, and a weak procurement and supply chain management system. This system for ARVs, paid for by the Global Fund to Fight AIDS, Tuberculosis and Malaria, and bypassing the government Central Medical Stores, is in place, using the United Nations Children's Fund's (UNICEF's) procurement services. The system, managed by a handful of people who spend limited time on supply management, is characterized by a centrally coordinated quantification based on verified data from all national ART clinics, parallel procurement through UNICEF, and direct distribution to ART clinics. The model worked well in the first years of the ART programme with a single first-line ARV regimen, but with more regimens becoming available (e.g., alternative first-line, second-line and paediatric regimens), it has become more difficult to administer. Managing supplies through a parallel system has the advantage that weaknesses in the national system have limited influence on the ARV procurement and supply chain management system. However, as the current system operates without a central warehouse and national buffer stock capacity, it diminishes the ability to prevent ARV stock outs. The process of ordering ARVs, from the time that estimates are made to the arrival of supplies in health facilities, takes approximately one year. Addressing the challenges involved in maintaining ARVs through an efficient procurement and supply chain management system that prevents ARV stock outs through the establishment of a dedicated procurement team, a central warehouse and/or national buffer stock is a

  20. HIV patients' decision of switching to second-line antiretroviral therapy in India.

    2015-01-01

    The objective is to examine when patients should switch to second-line antiretroviral therapy (ART) under health uncertainty and in the absence of viral load monitoring. We formalize and solve the therapeutic dilemma about whether or not, and when, to switch a therapy. The model's main value-added consists in the concrete application to patients with HIV in India. In our dynamic stochastic model, health level volatility can be understood as the variation in CD4 count and the trend of health level as increases in CD4 count and, thus, decreases in the incidence of opportunistic infections and mortality. The results of the empirical application suggest that the theoretical model can explain ART treatment switch. Treatment switch depends negatively on the volatility of patients' health, and on trend of health, i.e., the greater the variation in CD4 count and the more CD4 count increase, the fewer treatment switches one expects to occur. Treatment switch also depends negatively on the degree of irreversibility. Under irreversibility, low-risk patients must begin the second-line treatment as soon as possible, which is precisely when the second-line treatment is least valuable. The existence of an option value means that ART first-line regimen may be the better choice when considering lifetime welfare. Conversely, treatment switch depends positively on the discount rate and on the correlation between the patient's health under first- and second-line treatments. This means that treatment switch is likelier to succeed in second-line treatments that are similar to the first-line treatments, implying that a decision-maker should not rely on treatment switch as a risk diversification tool.

    Patient adherence (the degree to which patients follow their therapeutic regimen as prescribed within a set period of time) and persistence (the time to treatment discontinuation, with a permissible gap) with drug therapy are essential components of HIV/AIDS treatment. Select community pharmacies offer specialized services for HIV/AIDS patients to help combat some of the barriers to adherence and persistence. We assessed adherence and persistence with antiretroviral therapy (ART) for patients using HIV-specialized pharmacies in nine cities from seven states compared to traditional community pharmacy users over a 1-year period. Data were limited to one pharmacy chain. Propensity scoring was used to obtain 1:1 matches for "Specialized" and "Traditional" pharmacy users based on age, gender, number of prescription-inferred chronic conditions (obtained by mapping a patient's prescriptions to the Medi-Span Drug Indications Database), and presence of prescription anxiety and/or depression medication, resulting in 7064 patients in each group. Proportion of days covered (PDC) was used to measure adherence. Specialized pharmacy users had a significantly greater mean (74.1% versus 69.2%, p<0.0001) and median (90.3% versus 86.3%, p<0.0001) PDC. A greater percentage of patients in the Specialized group were able to obtain a PDC of 95% or better (39.3% versus 35.5%). Patients in the Specialized group were significantly more persistent (p=0.0117). Community pharmacies specialized in HIV services may be effective avenues for helping patients achieve greater adherence and persistence with ART. Given the value of specialized community pharmacies, payers should consider implementing policies to encourage the use of such pharmacies for filling ART. PMID:22860900

    The often cited need to achieve ≥95% (nearly perfect) adherence to antiretroviral therapy (ART) for successful virologic outcomes in HIV may present a barrier to initiation of therapy in the early stages of HIV.This meta-analysis synthesized 43 studies (27,905 participants) performed across >26 countries, to determine the relationship between cut-off point for optimal adherence to ART and virologic outcomes.Meta-analysis was performed using a random-effect model to calculate pooled odds ratios with corresponding 95% confidence intervals.The mean rate of patients reporting optimal adherence was 63.4%. Compared with suboptimal adherence, optimal adherence was associated with a lower risk of virologic failure (0.34; 95% CI: 0.26-0.44). There were no significant differences in the pooled odds ratios among different optimal adherence thresholds (≥98-100%, ≥95%, ≥80-90%). Study design (randomized controlled trial vs observational study) (regression coefficient 0.74, 95% CI: 0.04-1.43, P < 0.05) and study region (developing vs developed countries; regression coefficient 0.56, 95% CI: 0.01-1.12, P < 0.05) remained as independent predictors of between-study heterogeneity, with more patients with optimal adherence from developing countries or randomized controlled trials experiencing virologic failure.The threshold for optimal adherence to achieve better virologic outcomes appears to be wider than the commonly used cut-off point (≥95% adherence). The cut-off point for optimal adherence could be redefined to a slightly lower level to encourage the prescribing ART at an early stage of HIV infection. PMID:27082595

    OBJECTIVE: To investigate adherence to antiretroviral therapy and use of alternative therapies among older human immunodeficiency virus (HIV)-infected adults, and to assess relationships between antiretroviral adherence and clinical outcomes. METHODS: One hundred older HIV-infected patients, aged 50 and over, treated at two large HIV clinics in Washington, DC, were enrolled. A cross-sectional methodology used structured interviews to investigate antiretroviral regimens, use of alternative therapies, and demographics. Medical records provided viral load and CD4 count within 3 months of interview. RESULTS: The mean self-reported adherence was 94%, and 55 patients reported 100% adherence to antiretroviral therapy. Correlation analysis showed a significant negative correlation between adherence and viral load (r = -312, p = 0.005). There was no significant difference in adherence based on race, gender, mode of transmission, or education. Twenty-one patients (21%) reported the use of an alternative therapy, with several patients using multiple alternative therapies. There was no significant difference in adherence score (p = 0.514) or viral load (p = 0.860) based upon use of alternative therapies. CONCLUSIONS: Older HIV-infected study patients reported high levels of adherence to antiretroviral regimens, and adherence was highly correlated with HIV viral load. Use of alternative therapies did not significantly impact adherence to antiretroviral agents or viral load. High adherence among this older population may be related to older patients' familiarity with medication usage, their increasing awareness of HIV as a disease that requires optimal adherence, and educational efforts promoted by the two clinics in which they are clients.

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

    Objective Determine if incident AIDS-defining Kaposi sarcoma (KS) or Pneumocystis jiroveci pneumonia (PJP) is associated with combination antiretroviral therapy (cART) initiation. Design Compare risk for KS and PJP by time on cART and CD4 reconstitution. Methods In the FHDH-ANRS CO4 cohort (N=66,369), KS (N=1811) and PJP (N=1718) incidence rates were computed by demographic and HIV strata. Crude and adjusted relative risk (RR) with 95% confidence intervals (CI) following cART initiation were calculated by Poisson regression with untreated patients during 1996–2009 as reference. CD4 counts were compared by Wilcoxon rank sum tests. Results KS risk was very high during months 1–3 on cART (N=160, RRCrude 3.94, CI 3.26–4.76), which was incompletely attenuated by adjustment for demographics and contemporaneous CD4 count (RRAdj 1.25, CI 1.02–1.53). Corresponding PJP risk was minimally elevated (N=84, RRCrude 1.80, CI 1.42–2.30) and markedly reduced with adjustment on the same variables and PJP prophylaxis (RRAdj 0.52, CI 0.41–0.67). HIV load had no added effect. Median CD4 cell count at cART initiation was much lower in patients with incident KS (82/mm3) or PJP (61/mm3) within 3 months compared with those without (>250/mm3). Notably, median CD4 change was +44 cells/month with incident KS within 3 months of cART initiation versus 0 cells/month with incident PJP (P=0.0003). Conclusions Failure of CD4 reconstitution during months 1–3 on cART fully accounted for incident PJP. In contrast, there were 1.6 additional KS cases per 1000 person-years during months 1–3 on cART, suggesting that immune reconstitution may contribute to the risk for AIDS-defining KS. PMID:23196937

    It is now around 30 years since the discovery of HIV, the virus that causes AIDS. More than 70 million people have been infected in that time and around 35 million have died. The majority of those currently living with HIV/AIDS are in low- and middle-income countries, with sub-Saharan Africa bearing a disproportionate burden of the global disease. In high-income countries, the introduction of antiretroviral therapy (ART) has drastically reduced the morbidity and mortality associated with HIV. Patients on ART are now predicted to have near-normal life expectancy and the role of treatment is increasingly recognized in preventing new infections. In low- and middle-income countries, treatment is now more widely available and around half of those who need ART are currently receiving it. Early diagnosis of HIV is essential if ART is to be optimally implemented. Lab-based diagnostics for screening, diagnosis, treatment initiation, and the monitoring of treatment efficacy are critical in managing the disease and reducing the number of new infections each year. The introduction of point-of-care HIV rapid tests has transformed the epidemic, particularly in low- and middle-income countries. For the first time, these point-of-care tests allow for the rapid identification of infected individuals outside the laboratory who can undergo counseling and treatment and, in the case of pregnant women, allow the timely initiation of ART to reduce the risk of vertical transmission. Although survival is markedly improved with ART even in the absence of laboratory monitoring, long-term management of people living with HIV on ART, and their partners, is essential to ensure successful viral suppression. The burden of disease in many resource-poor settings with high HIV prevalence has challenged the ability of local laboratories to effectively monitor those on ART.

    The primary aim of this study was to measure HIV-1 persistence following combination antiretroviral therapy (cART) in infants and children. Peripheral blood mononuclear cell (PBMC) HIV-1 DNA was quantified prior to and after 1 year of cART in 30 children, stratified by time of initiation (early, age <3 months, ET; late, age >3 months-2 years, LT). Pre-therapy PBMC HIV-1 DNA levels correlated with pre-therapy plasma HIV-1 levels (r = 0.59, p<0.001), remaining statistically significant (p = 0.002) after adjustment for prior perinatal antiretroviral exposure and age at cART initiation. PBMC HIV-1 DNA declined significantly after 1 year of cART (Overall: -0.91±0.08 log10 copies per million PBMC, p<0.001; ET: -1.04±0.11 log10 DNA copies per million PBMC, p<0.001; LT: -0.74 ±0.13 log10 DNA copies per million PBMC, p<0.001) but rates of decline did not differ significantly between ET and LT. HIV-1 replication exposure over the first 12 months of cART, estimated as area-under-the-curve (AUC) of circulating plasma HIV-1 RNA levels, was significantly associated with PBMC HIV-1 DNA at one year (r = 0.51, p = 0.004). In 21 children with sustained virologic suppression after 1 year of cART, PBMC HIV-1 DNA levels continued to decline between years 1 and 4 (slope -0.21 log10 DNA copies per million PBMC per year); decline slopes did not differ significantly between ET and LT. PBMC HIV-1 DNA levels at 1 year and 4 years of cART correlated with age at cART initiation (1 year: p = 0.04; 4 years: p = 0.03) and age at virologic control (1 and 4 years, p = 0.02). Altogether, these data indicate that reducing exposure to HIV-1 replication and younger age at cART initiation are associated with lower HIV-1 DNA levels at and after one year of age, supporting the concept that HIV-1 diagnosis and cART initiation in infants should occur as early as possible.

    Objective Obesity and HIV-infection are associated with an increased incidence of non-infectious co-morbid medical conditions, but the relationship between body mass index (BMI) and the development of non-communicable diseases (NCDs) among individuals on antiretroviral therapy (ART) has not been well-characterized. Methods A cohort study of adults initiating ART between 1998 and 2010 at an academic center with systematic laboratory and clinical data collection, including AIDS and NCD diagnoses. The relationship between BMI at ART initiation and the risk of incident cardiovascular, hepatic, renal or oncologic NCDs was assessed using Cox proportional hazard models. BMI was fit using restricted cubic splines and models adjusted for age, sex, race, CD4+ count, protease inhibitor use, year of initiation, and prior AIDS-defining illness. Results Among 1089 patients in the analysis cohort, 54% had normal BMI, 28% were overweight, and 18% were obese. Baseline BMI was associated with developing an incident NCD (p=<0.01) but the relationship was non-linear. Compared to a BMI of 25 kg/m2, a BMI of 30 kg/m2 conferred a lower risk of an incident NCD diagnosis (HR 0.59; 95% CI: 0.40, 0.87). This protective effect was attenuated at a BMI of 35 kg/m2 (HR 0.78; 95% CI: 0.49, 1.23). Results were similar in sensitivity analyses incorporating tobacco, alcohol and drug use, statin and antihypertensive exposure, and virologic suppression. Conclusions Overweight individuals starting ART have a lower risk of developing NCDs compared to normal BMI individuals, which may reflect a biological effect of adipose tissue versus differences in patient or provider behaviors.

    Introduction Patients receiving antiretroviral therapy (ART) require routine monitoring to track response to treatment and assess for treatment failure. This study aims to identify gaps in monitoring practices in Kenya and Uganda. Methods We conducted a systematic retrospective chart review of adults who initiated ART between 2007 and 2012. We assessed the availability of baseline measurements (CD4 count, weight, and WHO stage) and ongoing CD4 and weight monitoring according to national guidelines in place at the time. Mixed-effects logistic regression models were used to analyze facility and patient factors associated with meeting monitoring guidelines. Results From 2007 to 2012, at least 88% of patients per year in Uganda had a recorded weight at initiation, while in Kenya there was a notable increase from 69% to 90%. Patients with a documented baseline CD4 count increased from 69% to about 80% in both countries. In 2012, 83% and 86% of established patients received the recommended quarterly weight monitoring in Kenya and Uganda, respectively, while semiannual CD4 monitoring was less common (49% in Kenya and 38% in Uganda). Initiating at a more advanced WHO stage was associated with a lower odds of baseline CD4 testing. On-site CD4 analysis capacity was associated with increased odds of CD4 testing at baseline and in the future. Discussion Substantial gaps were noted in ongoing CD4 monitoring of patients on ART. Although guidelines have since changed, limited laboratory capacity is likely to remain a significant issue in monitoring patients on ART, with important implications for ensuring quality care.

    Background Identifying characteristics of HIV-infected adults likely to have poor treatment outcomes can be useful for targeting interventions efficiently. Research in economics and psychology suggests that individuals’ intertemporal time preferences, which indicate the extent to which they trade-off immediate vs. future cost and benefits, can influence various health behaviors. While there is empirical support for the association between time preferences and various non-HIV health behaviors and outcomes, the extent to which time preferences predict outcomes of those receiving antiretroviral therapy (ART) has not been examined previously. Methods HIV-infected adults initiating ART were enrolled at a health facility in Kenya. Participants’ time preferences were measured at enrollment and used to classify them as having either a low or high discount rate for future benefits. At 48 weeks, we assessed mortality and ART adherence, as measured by Medication Event Monitoring System (MEMS). Logistic regression models adjusting for socio-economic characteristics and risk factors were used to determine the association between time preferences and mortality as well as MEMS adherence ≥90%. Results Overall, 44% (96/220) of participants were classified as having high discount rates. Participants with high discount rates had significantly higher 48-week mortality than participants with low discount rates (9.3% vs. 3.1%; adjusted odds ratio 3.84; 95% CI 1.03, 14.50). MEMS adherence ≥90% was similar for participants with high vs. low discount rates (42.3% vs. 49.6%, AOR 0.70; 95% CI 0.40, 1.25). Conclusion High discount rates were associated with significantly higher risk of mortality among HIV-infected patients initiating ART. Greater use of time preference measures may improve identification of patients at risk of poor clinical outcomes. More research is needed to further identify mechanisms of action and also to build upon and test the generalizability of this finding

    Abstract Adherence to antiretroviral therapy (ART) has markedly improved HIV disease management, and significantly reduced HIV/AIDS-associated morbidity and mortality. Although recent studies suggest a relationship between smoking and suboptimal adherence to ART, a more in-depth understanding of this relationship is needed. We conducted a secondary analysis using data from a randomized controlled smoking cessation trial to investigate the association of nonadherence to ART with potential demographic, psychosocial (perceived stress and depression), and substance use (nicotine dependence, illicit drug use, and alcohol use) variables among persons living with HIV/AIDS (PLWHA) who smoke. The mean (standard deviation [SD]) age of participants (n=326) was 45.9 years old (SD=7.6). Additionally, the majority were male (72.1%), self-identified as black (76.7%), and reported sexual contact as the mode of HIV acquisition (70%). Unadjusted logistic regression analysis indicated that depression (odds ratio [OR]=1.02; 95% confidence interval [CI]=1.00, 1.04), illicit drug use (OR=2.39; 95% CI=1.51, 3.79) and alcohol use (OR=2.86; 95%CI=1.79, 4.57) were associated with nonadherence. Adjusted logistic regression analysis indicated that nicotine dependence (OR=1.13; 95% CI=1.02, 1.25), illicit drug use (OR=2.10; 95% CI=1.27, 3.49), alcohol use (OR=2.50; 95% CI=1.52, 4.12), and age (OR=1.04; 95% CI=1.00, 1.07) were associated with nonadherence. Nicotine dependence, illicit drug use, and alcohol use are potentially formidable barriers to ART adherence among PLWHA who smoke. Future efforts should investigate the complex relationships among these variables to improve adherence particularly among populations confronted with multifaceted health challenges. PMID:22612468

    The human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome (AIDS) pandemic has entered its 4th decade. Since the introduction of combination antiretroviral therapy (ART) in 1996, the number of AIDS-related deaths has plateaued worldwide. Today, owing to the effectiveness of ART, the HIV-infected population is aging and HIV infection has become a chronic illness. Non-AIDS comorbidities are increasing, and the spectrum of HIV-related thoracic diseases is evolving. In developed countries, bacterial pneumonia has become more common than Pneumocystis pneumonia. Its imaging appearance depends on the responsible organism, most commonly Streptococcus pneumoniae. Mycobacterium tuberculosis continues to be a major threat. Its imaging patterns vary depending on CD4 count. Primary lung cancer and Hodgkin lymphoma are two important non–AIDS-defining malignancies that are increasingly encountered at chest imaging. Human herpesvirus 8, also known as Kaposi sarcoma–associated herpesvirus (KSHV), is strongly linked to HIV-related diseases, including Kaposi sarcoma, multicentric Castleman disease, KSHV inflammatory cytokine syndrome, and primary effusion lymphoma. Immune reconstitution inflammatory syndrome is a direct complication of ART whose manifestations vary with the underlying disease. Given the high rate of smoking among HIV-infected patients, chronic obstructive pulmonary disease is another important cause of morbidity and mortality. A high degree of suspicion is required for the early diagnosis of pulmonary arterial hypertension and lymphocytic interstitial pneumonia, given their nonspecific manifestations. Finally, multilocular thymic cyst manifests as a cystic anterior mediastinal mass. Recognition of the clinical and radiologic manifestations of these less traditional HIV-related diseases can expedite diagnosis and treatment in the ART era. © RSNA, 2014 PMID:25019430

    Objective To assess whether pregnancy is associated with an increased risk of liver enzyme elevation (LEE) and severe LEE in HIV-positive women on antiretroviral therapy (ART). Design Two observational studies; the UK Collaborative HIV Cohort (UK CHIC) study and the UK and Ireland National Study of HIV in Pregnancy and Childhood (NSHPC). Methods Combined data from UK CHIC and NSHPC were used to identify factors associated with LEE (grade 1-4) and severe LEE (grade 3-4). Women starting ART in 2000-2012 were included irrespective of pregnancy status. Cox proportional hazards were used to assess fixed and time-dependent covariates including pregnancy status, CD4 count, drug regimen and hepatitis B/C (HBV/HCV) co-infection. Results One-quarter (25.7%, 982/3815) of women were pregnant during follow-up; 14.2% (n=541) when starting ART. The rate of LEE was 14.5/100 person-years (PY) in and 6.0/100 PY outside of pregnancy. The rate of severe LEE was 3.9/100 PY in and 0.6/100 PY outside of pregnancy. The risk of LEE and severe LEE was increased during pregnancy (LEE: aHR 1.66 [1.31-2.09]; severe LEE: aHR 3.57 [2.30-5.54]), including in secondary analyses excluding 541 women pregnant when starting ART. Other factors associated with LEE and severe LEE included lower CD4 count (<250 cells/mm3), HBV/HCV co-infection and calendar year. Conclusions Although few women developed severe LEE, this study provides further evidence that pregnancy is associated with increased risk of LEE and severe LEE, reinforcing the need for regular monitoring of liver biomarkers during pregnancy.

    Thirty years after HIV first appeared it has killed close to 30 million people but transmission continues unchecked. In 2009, an estimated 1.8 million lives were lost and 2.6 million more people were infected with HIV [1]. To cut transmission, many social, behavioural and biomedical interventions have been developed, tested and tried but have had little impact on the epidemic in most countries. One substantial success has been the development of combination antiretroviral therapy (ART) that reduces viral load and restores immune function. This raises the possibility of using ART not only to treat people but also to prevent new HIV infections. Here we consider the impact of ART on the transmission of HIV and show how it could help to control the epidemic. Much needs to be known and understood concerning the impact of early treatment with ART on the prognosis for individual patients and on transmission. We review the current literature on factors associated with modelling treatment for prevention and illustrate the potential impact using existing models. We focus on generalized epidemics in sub- Saharan Africa, with an emphasis on South Africa, where transmission is mainly heterosexual and which account for an estimated 17% of all people living with HIV. We also make reference to epidemics among men who have sex with men and injection drug users where appropriate. We discuss ways in which using treatment as prevention can be taken forward knowing that this can only be the beginning of what must become an inclusive dialogue among all of those concerned to stop acquired immune deficiency syndrome (AIDS).

    BACKGROUND The natural history and manifestation of HIV-related neurological disease have been ameliorated by combination antiretroviral therapy (ART). We describe the characteristics of white matter signal abnormalities (WMSA) on magnetic resonance imaging (MRI) in children with HIV-related neurological disease. METHODS We reviewed MRI scans of children with suspected HIV-related neurological disease despite early ART, and correlated with clinical, neurodevelopmental data, virological markers and time on ART. These children were also on the Children with HIV Early Antiretroviral (CHER) trial. RESULTS MRI scans were performed at a mean age 31.9 months (range 8-54) on 44 children: 10 on deferred and 34 on early treatment arms, commencing ART at mean age of 18.5 and 8 weeks respectively. Multiple high signal intensity lesions on T2 /FLAIR were documented in 22 patients (50%), predominantly in frontal (91%) and parietal (82%) white matter. No differences in neurodevelopmental scores comparing children with and without WMSA were found. Neither lesion load nor distribution showed significant correlation with neurodevelopmental scores or neurological examination. Normal head growth was more common in the WMSA group (p=0.01). There was a trend for association of WMSA and longer time on ART (p=0.13) and nadir CD4% (p=0.08). CONCLUSION Half of children referred with HIV-related brain disease had WMSA on T2/FLAIR. Our findings of the association with normal head growth and duration of ART require further study. We suspect that WMSA can occur early and that initiating ART by 8 weeks of life may be too late to prevent HIV from entering the CNS. PMID:24595047

    Objective: To assess factors at the start of antiretroviral therapy (ART) associated with long-term virological response in children. Design: Multicentre national cohort. Methods: Factors associated with viral load below 400 copies/ml by 12 months and virologic failure among children starting 3/4-drug ART in the UK/Irish Collaborative HIV Paediatric Study were assessed using Poisson models. Results: Nine hundred and ninety-seven children started ART at a median age of 7.7 years (inter-quartile range 2.9–11.7), 251 (25%) below 3 years: 411 (41%) with efavirenz and two nucleoside reverse transcriptase inhibitors (EFV + 2NRTIs), 264 (26%) with nevirapine and two NRTIs (NVP + 2NRTIs), 119 (12%; 106 NVP, 13 EFV) with non-nucleoside reverse transcriptase inhibitor and three NRTIs (NNRTI + 3NRTIs), and 203 (20%) with boosted protease inhibitor-based regimens. Median follow-up after ART initiation was 5.7 (3.0–8.8) years. Viral load was less than 400 copies/ml by 12 months in 92% [95% confidence interval (CI) 91–94%] of the children. Time to suppression was similar across regimens (P = 0.10), but faster over calendar time, with older age and lower baseline viral load. Three hundred and thirty-nine (34%) children experienced virological failure. Although progression to failure varied by regimen (P < 0.001) and was fastest for NVP + 2NRTIs regimens, risk after 2 years on therapy was similar for EFV + 2NRTIs and NVP + 2NRTIs, and lowest for NNRTI + 3NRTIs regimens (P-interaction = 0.03). Older age, earlier calendar periods and maternal ART exposure were associated with increased failure risk. Early treatment discontinuation for toxicity occurred more frequently for NVP-based regimens, but 5-year cumulative incidence was similar: 6.1% (95% CI 3.9–8.9%) NVP, 8.3% (95% CI 5.6–11.6) EFV, and 9.8% (95% CI 5.7–15.3%) protease inhibitor-based regimens (P = 0.48).

    Background Antiretroviral therapy (ART) reduces the risk of tuberculosis, but the incidence still exceeds that in HIV-uninfected people. Isoniazid preventive therapy (IPT), which decreases the risk of tuberculosis in people not on ART, may offer additional protection. Methods Pragmatic randomized double-blind placebo-controlled trial to evaluate the effect of 12 months IPT among participants established on or newly starting ART, in Khayelitsha, South Africa (NCT00463086, Lancet D-09-02885). Tuberculosis was excluded at screening by sputum culture. Incident tuberculosis was the primary endpoint. Findings 1,329 participants contributed 3,227 person-years (PY) of follow up in the modified intention-to-treat analysis; 662 on IPT and 667 on placebo. There were 95 incident tuberculosis cases: 2.3 (95%CI 1.6-3.1) versus 3.6 (95%CI 2.8-4.7) per 100 PY in the IPT and placebo arms respectively (hazard ratio 0.63, 95%CI 0.41-0.94). Study drug was discontinued due to grade 3 or 4 raised ALT in 19/662 in the IPT and 10/667 in the placebo arm, risk ratio=1.9 (95%CI 0.90-4.09). In secondary analyses, there was no evidence that the effect of IPT was restricted to those who were positive on tuberculin skin test (TST) or interferon gamma release assay (IGRA): adjusted hazard ratio for those with negative tests 0.43 (95%CI 0.21-0.86) and 0.43 (95%CI 0.20-0.96); for positive tests 0.86 (95%CI 0.37-2.00) and 0.55 (95%CI 0.26-1.24) respectively. No all cause mortality benefit of IPT was demonstrated Interpretation IPT reduced the incidence of tuberculosis in HIV-infected individuals on ART. In this high incidence setting, individuals on ART who have TST or IGRA negative results may also benefit from IPT. IPT can easily be implemented in ART clinics. PMID:24835842

    We investigate mutations and correlates according to HIV-1 subtype after virological failure (VF) of standard first-line antiretroviral therapy (ART) (non-nucleoside/nucleotide reverse transcriptase inhibitor [NNRTI] +2 nucleoside/nucleotide reverse transcriptase inhibitor [N(t)RTI]). SECOND-LINE study participants were assessed at baseline for HIV-1 subtype, demographics, HIV-1 history, ART exposure, viral load (VL), CD4(+) count, and genotypic ART resistance. We used backward stepwise multivariate regression (MVR) to assess associations between baseline variables and presence of ≥3 N(t)RTI mutations, ≥1 NNRTI mutation, ≥3 thymidine analog-N(t)RTI [ta-N(t)RTI] mutations (TAMs), the K65/K70 mutation, and predicted etravirine (ETV)/rilpivirine (RPV) activity. The inclusion p-value for MVR was p < .2. The exclusion p-value from stepwise elimination was p > .05. Of 541 participants, 491 (91%) had successfully characterized baseline viral isolates. Subtype distribution: B (n = 123, 25%), C (n = 202, 41%), CRF01_AE (n = 109, 22%), G (n = 25, 5%), and CRF02_AG (n = 27, 5%). Baseline CD4(+) 200-394 cells/mm(3) were associated with <3 N(t)RTI mutations (OR = 0.47; 95% CI 0.29-0.77; p = .003), absence of the K65/K70 mutation (OR = 0.43; 95% CI 0.26-0.73; p = .002), and higher ETV sensitivity (OR = 0.52; 95% CI 0.35-0.78; p = .002). Recent tenofovir (TDF) use was associated with K65/K70 mutations (OR = 8.91; 95% CI 5.00-15.85; p < .001). Subtype CRF01_AE was associated with ≥3 N(t)RTI mutations (OR = 2.34; 95% CI 1.31-4.17; p = .004) and higher RPV resistance (OR = 2.13; 95% CI 1.30-3.49; p = .003), and subtype C was associated with <3 TAMs (OR = 0.45; 95% CI 0.21-0.99; p = .015). Subtypes CRF01_AE (OR = 2.46; 95% CI 1.26-4.78; p = .008) and G (OR = 4.77; 95% CI 1.44-15.76; p = .01) were associated with K65/K70 mutations. Higher VL at confirmed first-line VF was

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

    Background Lack of early initiation of antiretroviral therapy (ART) remains a major health concern due to increased risk of premature mortality and further HIV transmission. This study explored CD4+ cell count monitoring in relation to delays in ART initiation among HIV-positive individuals in the Kathmandu Valley, Nepal, where ART coverage was only 23.7% in 2011. Design We recruited a total of 87 ART-naïve, HIV-positive individuals aged 18 to 60 years through the networks of five non-government organizations working with HIV-positive individuals. We collected data on the history of ART initiation, CD4+ cell count monitoring, socio-demographic variables, perceived family support (measured with 10-item Nepali Family Support and Difficulty Scale), depression, and HIV symptom burden. Correlates of ART eligibility were examined using multivariable logistic regression analysis. Results A total of 72 of the 87 ART-naïve participants (82.8%) had monitored their CD4+ cell count in the past 6 months. Of these, 36 (50%) participants were eligible for ART initiation with CD4+ cell count <350 cells/mm3. A total of 12 participants had CD4+ cell count <200 cells/mm3. Lower level of perceived family support was associated with 6.05-fold higher odds (95% confidence interval =1.95 to 18.73) of being ART eligible with a CD4+ cell count <350 cells/mm3. Conclusions High rate of delays in ART initiation and the strong association of low perceived family support with ART eligibility in our study participants suggest that HIV service providers should consider the role and impact of family support in influencing individual decisions to initiate ART among eligible HIV-positive individuals.

    Background Antiretroviral drugs have been shown to reduce risk of mother-to-child transmission of human immunodeficiency virus (HIV) and are also widely used for post-exposure prophylaxis for parenteral and sexual exposures. Sexual transmission may be lower in couples in which one partner is infected with HIV and the other is not and the infected partner is on antiretroviral therapy (ART). Objectives To determine if ART use in an HIV-infected member of an HIV-discordant couple is associated with lower risk of HIV transmission to the uninfected partner compared to untreated discordant couples. Search methods We used standard Cochrane methods to search electronic databases and conference proceedings with relevant search terms without limits to language. Selection criteria Randomised controlled trials (RCT), cohort studies and case-control studies of HIV-discordant couples in which the HIV-infected member of the couple was being treated or not treated with ART Data collection and analysis Abstracts of all trials identified by electronic or bibliographic scanning were examined independently by two authors. We initially identified 3,833 references and examined 87 in detail for study eligibility. Data were abstracted independently using a standardised abstraction form. Main results One RCT and nine observational studies were included in the review. These ten studies identified 2,112 episodes of HIV transmission, 1,016 among treated couples and 1,096 among untreated couples. The rate ratio for the single randomised controlled trial was 0.04 [95% CI 0.00, 0.27]. All index partners in this study had CD4 cell counts at baseline of 350–550 cells/µL. Similarly, the summary rate ratio for the nine observational studies was 0.58 [95% CI 0.35, 0.96], with substantial heterogeneity (I2=64%). After excluding two studies with inadequate person-time data, we estimated a summary rate ratio of 0.36 [95%CI 0.17, 0.75] with substantial heterogeneity (I2=62%). We also performed

    Antiretroviral treatment services for Papua New Guineans infected with HIV (human immunodeficiency virus) have been severely limited because of the expense and difficulty in gaining access to antiretroviral drugs and the tests that are required to monitor the response of patients to them. Because some Papua New Guineans are beginning to seek out these services in Australia, clinicians are being challenged to manage the condition properly across an international border. Several case histories presented here highlight such difficulties. Progress is being made to reduce drug prices and simplify tablet-taking regimens, which has made the use of antiretroviral therapy more feasible. We briefly discuss infrastructure requirements for the more widespread provision of antiretroviral treatment services within Papua New Guinea. PMID:16496512

    Objectives The objectives of this study were to determine 1) the expression of oral pro-inflammatory cytokines in HIV-infected subjects compared with non-HIV individuals, 2) the cytokine expression in the subjects with antiretroviral therapy (ART) compared with those without ART, and 3) factors associated with the expression of the cytokines. Materials and methods Oral examination was performed and saliva samples were collected and analyzed for the expression of pro-inflammatory cytokines using ELISA. Logistic regression analysis was performed to determine the association between HIV/ART status and the cytokine expression. Results One hundred and fifty-seven HIV-infected subjects with and without ART, and 50 non-HIV individuals were enrolled. TNF-α and IL-6 in saliva were significantly decreased, while IL-8 was significantly increased in HIV infection (p< 0.05). Changes in the expression of IL-8 was also observed between HIV-infected subjects who were and were not on ART (p< 0.05). Duration of HIV infection and smoking were significantly associated with the expression of pro-inflammatory cytokines in saliva (p< 0.05). Conclusion Oral innate immunity is affected by HIV infection and use of ART. IL-8 may be the useful biomarker to identify subjects at risk of infection and malignant transformation due to HIV infection and long-term use of ART. PMID:23718561

    Understanding factors that influence pregnancy decision-making and experiences among HIV-positive women is important for developing integrated reproductive health and HIV services. Few studies have examined HIV-positive women's navigation through the social and clinical factors that shape experiences of pregnancy in the context of access to antiretroviral therapy (ART). We conducted 25 semistructured interviews with HIV-positive, pregnant women receiving ART in Mbarara, Uganda in 2011 to explore how access to ART shapes pregnancy experiences. Main themes included: (1) clinical counselling about pregnancy is often dissuasive but focuses on the importance of ART adherence once pregnant; (2) accordingly, women demonstrate knowledge about the role of ART adherence in maintaining maternal health and reducing risks of perinatal HIV transmission; (3) this knowledge contributes to personal optimism about pregnancy and childbearing in the context of HIV; and (4) knowledge about and adherence to ART creates opportunities for HIV-positive women to manage normative community and social expectations of childbearing. Access to ART and knowledge of the accompanying lowered risks of mortality, morbidity, and HIV transmission improved experiences of pregnancy and empowered HIV-positive women to discretely manage conflicting social expectations and clinical recommendations regarding childbearing.

    As antiretroviral treatment of HIV infection has become increasingly accessible, attention has focused on whether these drugs can used for prevention because of increased tolerability of newer medications, decreased cost, and the limitations of other approaches. We review the status of antiretroviral HIV prevention, including chemoprophylaxis, as well as the effects of treatment of infected individuals on prevention. It is possible that the life-saving agents that have transformed the natural history of AIDS can be a critical component of HIV prevention efforts, but their ultimate role in affecting HIV transmission dynamics remains to be defined.

    Aims Cleft lip/palate, though rare, is the commonest head and neck congenital malformation. Both genetic and environmental factors have been implicated in the aetiopathogenesis but the role of in-utero exposure to human immunodeficiency virus (HIV) and highly active antiretroviral therapy (HAART) is still being investigated. This short communication reports the occurrence of cleft palate in three newborns exposed in-utero to HIV and HAART. Material and methods This is a case series of HIV-exposed newborns observed to have cleft palate among a larger cohort of HIV-exposed and unexposed newborns in a study evaluating the effect of HIV infection and HAART on newborn hearing. The Risk Ratio (RR) was calculated to detect a potential association between in-utero exposure to Efavirenz containing ART and cleft palate. Results Three HIV-exposed newborns with cleft palate were identified during hearing screening performed on 126 HIV-exposed and 121 HIV unexposed newborns. Two had exposure to tenofovir+lamivudine+efavirenz (TDF+3TC+EFV) while the third had exposure to zidovudine+lamivudine+nevirapine (ZDV+3TC+NVP) during the first trimester. There was no statistically significant association between presence of cleft palate and exposure to an EFV containing HAART regimen (p=0.07, RR=10.95 [0.94-126.84]). Conclusions This communication highlights the possible aetiologic role of HAART in cleft palate, the need for further prospective follow-up studies and establishment of antiretroviral pregnancy, birth and neonatal registries.

    Objective To explore nurse and facility and programme manager perceptions of nurse initiated and managed antiretroviral therapy (NIMART) implementation in Gauteng, South Africa. Design In this qualitative study, in-depth interviews and focus group discussions were conducted to gain insight into participants’ experiences of NIMART implementation. Setting Participants came from urban, peri-urban and rural primary healthcare clinics in two Gauteng Province municipalities. Participants 25 nurses and 18 managers who were actively involved in NIMART implementation were purposively sampled. Results The findings from this study reveal that, despite encountering numerous challenges including human resources, training and clinical mentoring and health systems issues, NIMART nurses and managers remained optimistic about their work. Study participants felt empowered by their expanded roles. Increased responsibilities associated with NIMART implementation encouraged better use of creative problem-solving and teamwork to facilitate integration of NIMART into existing clinic services. NIMART nurses perceived antiretroviral therapy (ART) patients to be more insightful about their illness, engaged in their HIV treatment and aware of the importance of adherence which enhanced nurse–patient relationships and increased their sense of job satisfaction. Conclusions Although the implementation of NIMART is complex, when NIMART is implemented well, ART access is increased and patient outcomes are improved. Supportive interventions which address the specific challenges faced by nurses providing NIMART now need to be implemented. Attempts should be made to replicate the positive aspects of NIMART implementation identified by participants as this may improve healthcare providers’ experiences of task-shifting. PMID:24240142

    Introduction Recent international guidelines call for expanded access to triple-drug antiretroviral therapy (ART) in HIV-positive women during pregnancy and postpartum. However, high levels of non-adherence and/or disengagement from care may attenuate the benefits of ART for HIV transmission and maternal health. We examined the frequency and predictors of disengagement from care among women initiating ART during pregnancy in Cape Town, South Africa. Methods We used routine medical records to follow-up pregnant women initiating ART within prevention of mother-to-child transmission of HIV services in Cape Town, South Africa. Outcomes assessed through six months postpartum were (1) disengagement (no attendance within 56 days of a scheduled visit) and (2) missed visits (returning to care 14–56 days late for a scheduled visit). Results A total of 358 women (median age, 28 years; median gestational age, 26 weeks) initiated ART during pregnancy. By six months postpartum, 24% of women (n=86) had missed at least one visit and an additional 32% (n=115) had disengaged from care; together, 49% of women had either missed a visit or had disengaged by six months postpartum. Disengagement was more than twice as frequent postpartum compared to in the antenatal period (6.2 vs. 2.4 per 100 woman-months, respectively; p<0.0001). In a proportional hazards model, later gestational age at initiation (HR: 1.04; 95% CI: 1.00–1.07; p=0.030) and being newly diagnosed with HIV (HR: 1.57; 95% CI: 1.07–2.33; p=0.022) were significant predictors of disengagement after adjusting for patient age, starting CD4 cell count and site of ART initiation. Conclusions These results demonstrate that missed visits and disengagement from care occur frequently, particularly post-delivery, among HIV-positive women initiating ART during pregnancy. Women who are newly diagnosed with HIV may be particularly vulnerable and there is an urgent need for interventions both to promote retention overall, as well as

    Objective: The objective of this study is to assess the risk of viral rebound in postpartum women on suppressive combination antiretroviral therapy (cART). Methods: Using data from the UK Collaborative HIV Cohort (UK CHIC) study and the UK and Ireland National Study of HIV in Pregnancy and Childhood (NSHPC), women with HIV-RNA 50 copies/ml or less at delivery in 2006–2011, who started life-long cART during pregnancy (n = 321) or conceived on cART (n = 618), were matched by age, duration on cART and time period, with at least one control (non-postpartum). The cumulative probability of viral rebound (HIV-RNA >200 copies/ml) was assessed by Kaplan–Meier analysis; adjusted hazard ratios (aHRs) for the 0–3 and 3–12 months postdelivery (cases)/pseudo-delivery (controls) were calculated in Cox proportional hazards models. Results: In postpartum women who conceived on cART, 5.9% [95% confidence interval (95% CI) 4.0–7.7] experienced viral rebound by 3 months, and 2.2% (1.4–3.0%) of their controls. The risk of viral rebound was higher in postpartum women than in controls during the first 3 months [aHR 2.63 (1.58–4.39)] but not during the 3–12 months postdelivery/pseudo-delivery. In postpartum women who started cART during pregnancy, 27% (22–32%) experienced viral rebound by 3 months, and 3.0% (1.6–4.4%) of their controls. The risk of viral rebound was higher in postpartum women than in controls during both postdelivery/pseudo-delivery periods [<3 months: aHR 6.63 (3.58–12.29); 3–12 months: aHR 4.05 (2.03–8.09)]. Conclusion: In women on suppressive cART, the risk of viral rebound is increased following delivery, especially in the first 3 months, which may be related to reduced adherence, indicating the need for additional adherence support for postpartum women.

    Opportunistic parasite infections (OPIs) are an important cause of morbidity and mortality in persons infected with HIV. In industrialised countries, the use of Highly Active AntiRetroviral Therapy (HAART) results to be effective in suppressing the HIV viral load, with a quantitative and qualitative improvement in the CD4+ T-cell count followed by a strong reduction of opportunistic infections including those caused by parasites. These successes have been mainly attributed to the reconstitution of the cell immunity, which play the most important role in controlling OPIs. However, there are many clinical reports and several laboratory results, which suggest that the control of OPIs in HIV-positive persons under HAART is also induced by the anti-HIV protease inhibitors (PIs), which inhibit the aspartyl proteases of the parasites. The non-conventional use of HIV-PIs seems to be an alternative way for the treatment of parasitic infections, which should be deeply investigated. Of five longitudinal studies carried out before and after the introduction of HAART, four studies showed a strong reduction of toxoplasmic encephalitis (TE) in HIV-positive persons under HAART, whereas in another study, no difference was observed in the incidence rate of TE before and after the introduction of HAART. The influence of HAART in reducing TE has been also confirmed in a randomised, controlled clinical trial, which showed that there is no increase in the risk of developing TE after beginning HAART, even though HIV-infected persons with TE had a discontinuing prophylaxis for Toxoplasma gondii. Four HIV protease inhibitors were tested against the T. gondii virulent RH strain in vitro, alone or in association with pyrimethamine or sulfadiazine. Ritonavir and nelfinavir were highly inhibitory for the parasite growth. Furthermore, none of the antiviral drugs negatively affected the anti-Toxoplasma activity of pyrimethamine or sulfadiazine.

    Alcohol-antiretroviral therapy (ART) interactive toxicity beliefs reflect perceived adverse outcomes of mixing alcohol and ART. Previous research has shown a significant relationship between alcohol-ART interactive toxicity beliefs and ART non-adherence, over and above other correlates of non-adherence such as human immunodeficiency virus (HIV)symptoms and frequency of alcohol use. Most past studies have collected data over extended periods and have not determined if alcohol use and missed medications occur at the day-level among people holding interactive toxicity beliefs. Previous daily analyses, however, have been limited by self-reported adherence and relatively short periods of observation. To address these gaps in the literature, men and women living with HIV in Atlanta, GA, were enrolled in a 45-day observational cohort study. Daily alcohol use was collected using two-way interactive text message surveys and daily adherence was collected via the Wisepill device. Fifty-seven participants completed a measure of alcohol-ART interactive toxicity beliefs and contributed 2565 days of daily data. Participants who endorsed high levels of interactive toxicity beliefs had significantly more days when they missed doses of medication. Alcohol-antiretroviral toxicity beliefs predicted missing doses of medication on days when participants were drinking and on days when they were not drinking. Multilevel multivariate regressions showed that these toxicity beliefs predicted daily missed doses of medication over and above quantity of alcohol consumed, depression and general medication concerns. This study replicates and extends previous literature and indicates the necessity of addressing alcohol-ART toxicity beliefs within adherence interventions. PMID:26964014

    Background Introduction of antiretroviral therapy (ART) has shown reduction in HIV-related mortality and morbidity in people living with HIV and AIDS. Since high levels of adherence of more than 95.0% is required to achieve effective suppression of viral load, researchers found it important to establish whether people are pursuing what is expected of them. Aim and setting The study was aimed at determining adherence to ART among HIV and AIDS patients at the Kwa-Thema clinic in Gauteng Province Methods Quantitative cross-sectional descriptive design was used. Ethical clearance was sort from MEDUNSA Research Ethics Committee. Validity and reliability were maintained throughout the study. A non-probability systematic sampling was used. Data were collected using administered structured questionnaire, and a total of 290 respondents were involved. Data were analysed using SPSS software version 22. Results The findings indicated that the adherence to ART was 77.0%. Factors that were significantly associated with adherence were gender (χ2 = 3.78, df = 1, p < 0.05), level of education (χ2 = 3.52, df = 3, p = 0.032), co-treatment of HIV and other infections (χ2 = 5.46, df = 4, p = 0.019), ability to follow ART (χ2 = 12.82, df = 1, p = 0.000 < 0.05), and types of antiretroviral drugs. Recommendation The study recommends intensification of health education campaign against stigma and gender discrimination. Providing feedback to patients regarding benefits of ART is important. Conclusion The study concluded that adherence to ART at the Kwa-Thema clinic was sub-optimal (less than 95%) at 77%, but comparable with the adherence levels in other developing countries.

    Replication-competent human immunodeficiency virus (HIV) persists in infected people despite suppressive combination antiretroviral therapy (cART), and it represents a major obstacle to HIV functional cure or eradication. We have developed a model of cART-mediated viral suppression in simian human immunodeficiency virus (SIV) mac239-infected Indian rhesus macaques and evaluated the impact of the histone deacetylase inhibitor (HDACi) romidepsin (RMD) on viremia in vivo. Eight macaques virologically suppressed to clinically relevant levels (<30 viral RNA copies/ml of plasma), using a three-class five-drug cART regimen, received multiple intravenous infusions of either RMD (n = 5) or saline (n = 3) starting 31 to 54 weeks after cART initiation. In vivo RMD treatment resulted in significant transient increases in acetylated histone levels in CD4(+) T cells. RMD-treated animals demonstrated plasma viral load measurements for each 2-week treatment cycle that were significantly higher than those in saline control-treated animals during periods of treatment, suggestive of RMD-induced viral reactivation. However, plasma virus rebound was indistinguishable between RMD-treated and control-treated animals for a subset of animals released from cART. These findings suggest that HDACi drugs, such as RMD, can reactivate residual virus in the presence of suppressive antiviral therapy and may be a valuable component of a comprehensive HIV functional cure/eradication strategy.

    South Africa has the largest global HIV/AIDS epidemic, but barriers along the HIV care continuum prevent patients from initiating and adhering to antiretroviral therapy (ART). To qualitatively explore reasons for poor ART initiation and adherence rates from the unique perspective of community health workers (CHWs), we conducted focus groups during May-August 2014 with 21 CHWs in rural Msinga, KwaZulu-Natal. Interviews were audio-recorded, transcribed, and translated from Zulu into English. Hybrid deductive and inductive analytical methods were applied to identify emergent themes. Multiple psychosocial, socioeconomic, and socio-medical barriers acted at the level of the individual, social network, broader community, and healthcare environment to simultaneously hinder initiation of and adherence to ART. Key themes included insufficient patient education and social support, patient dissatisfaction with healthcare services, socioeconomic factors, and tension between ART and alternative medicine. Fear of lifelong therapy thwarted initiation whereas substance abuse principally impeded adherence. In conclusion, HIV/AIDS management requires patient counselling and support extending beyond initial diagnosis. Treating HIV/AIDS as a chronic rather than acute infectious disease is key to improving ART initiation and long-term adherence. Public health strategies include expanding CHWs' roles to strengthen healthcare services, provide longitudinal patient support, and foster collaboration with alternative medicine providers.

Increases in CD4 cell count and BMI were similar, whereas elevations of hepatic transaminases were more frequent in both the occult HBV and HBsAg+ patients. Occult HBV/HIV co-infection appears not to impact adversely on response to antiretroviral therapy in Ghana. PMID:22874516

    High activity antiretroviral therapy may exacerbate the activity of ergot alkaloids due to an inhibition of cytochrome P450. We report a 57 years old female with AIDS treated with lamivudine, zidovudine, atazanavir, ritonavir and cotrimoxazole presenting with ischemic signs in the four limbs. There was acrocyanosis and weak radial and ulnar pulses. A family member referred that the patient used ergot alkaloids for headaches. An ergotism due to the simultaneous use of ergot alkaloids and antiretroviral therapy was suspected. The latter was discontinued and intravenous nitroglycerin, nifedipine and pentoxifyline were started with good results. PMID:27598502

    We report a case of Strongyloides stercoralis hyperinfection syndrome with central nervous system involvement, in a patient with late human immunodeficiency virus (HIV) infection starting antiretroviral therapy, in whom Strongyloides stercoralis larvae and Cryptococcus neoformans were isolated antemortem from cerebrospinal fluid. Our patient was not from an endemic region for the parasite, so strongyloidiasis was not originally suspected. For this reason, we conclude that Strongyloides stercoralis infection should be suspected in HIV-infected patients starting antiretroviral therapy in order to avoid potential fatal outcomes.

    Introduction Compliance to Antiretroviral Therapy (ART) is a primary determinant of treatment success of HIV-AIDS. Many studies have shown inadequate compliance to ART in the Indian population. Aim To assess the compliance to ART among HIV infected patients, to explore the factors affecting compliance and impact of compliance on CD4 count. Materials and Methods A cross-sectional study was conducted with 200 adult patients attending ART center, KIMS, Hubli. The patients were randomly selected and compliance to ART over preceding 3 months was assessed. Reasons for non- compliance were assessed among those with inadequate compliance. Results Mean age of the study population was 40.07±9.99 years. The sex ratio was 1.02:1 (M:F). Majority of patients were in WHO stage 1 with treatment, with CD4 count above 500/μl. Pulmonary tuberculosis was the most common opportunistic infection. Most of the patients were on long term ART, more than 5 years {81 (40.5%)}. Most of the patients were on ZLN regimen {97 (48.5%)}. Compliance over the preceding 3 months was 94.84± 14.93% for ART and 88.97±23.75% for opportunistic infection prophylaxis. There was no significant difference in compliance in relation to age group, sex, educational status, residence, religion, habits, HIV status of spouse or child, the regimen of ART and frequency of dosing. The compliance was better among those on long term treatment, i.e., those on treatment for more than 5 years compared to those who started ART in last 1 year (p=0.06). The most common reasons given by patients for non-compliance were going away from home, busy with other work and simply forgot. Better compliance was associated with higher CD4 count. Conclusion Compliance to ART was inadequate in the studied population, which is a major obstacle to success of ART. PMID:27437267

    Objective: The incidence of human papillomavirus (HPV)-related oral malignancies is increasing among HIV-infected populations, and the prevalence of oral warts has reportedly increased among HIV patients receiving antiretroviral therapy (ART). We explored whether ART initiation among treatment-naive HIV-positive adults is followed by a change in oral HPV infection or the occurrence of oral warts. Design: Prospective, observational study. Methods: HIV-1 infected, ART-naive adults initiating ART in a clinical trial were enrolled. End points included detection of HPV DNA in throat-washes, changes in CD4+ T-cell count and HIV RNA, and oral wart diagnosis. Results: Among 388 participants, 18% had at least one HPV genotype present before initiating ART, and 24% had at least one genotype present after 12–24 weeks of ART. Among those with undetectable oral HPV DNA before ART, median change in CD4+ count from study entry to 4 weeks after ART initiation was larger for those with detectable HPV DNA during follow-up than those without (P =  0.003). Both prevalence and incidence of oral warts were low (3% of participants having oral warts at study entry; 2.5% acquiring oral warts during 48 weeks of follow-up). Conclusion: These results suggest: effective immune control of HPV in the oral cavity of HIV-infected patients is not reconstituted by 24 weeks of ART; whereas ART initiation was not followed by an increase in oral warts, we observed an increase in oral HPV DNA detection after 12–24 weeks. The prevalence of HPV-associated oral malignancies may continue to increase in the modern ART era. PMID:26919735

    High-level T cell expression of PD-1 during SIV infection is correlated with impaired proliferation and function. We evaluated the phenotype and distribution of T cells and Tregs during antiretroviral therapy plus PD-1 modulation (using a B7-DC-Ig fusion protein) and post-ART. Chronically SIV-infected rhesus macaques received: 11 weeks of ART (Group A); 11 weeks of ART plus B7-DC-Ig (Group B); 11 weeks of ART plus B7-DC-Ig, then 12 weeks of B7-DC-Ig alone (Group C). Continuous B7-DC-Ig treatment (Group C) decreased rebound viremia post-ART compared to pre-ART levels, associated with decreased PD-1{sup hi} expressing T cells and Tregs in PBMCs, and PD-1{sup hi} Tregs in lymph nodes. It transiently decreased expression of Ki67 and α{sub 4}β{sub 7} in PBMC CD4{sup +} and CD8{sup +} Tregs for up to 8 weeks post-ART and maintained Ag-specific T-cell responses at low levels. Continued immune modulation targeting PD-1{sup hi} cells during and post-ART helps maintain lower viremia, keeps a favorable T cell/Treg repertoire and modulates antigen-specific responses. - Highlights: • B7-DC-Ig modulates PD-1{sup hi} cells in SIV-infected rhesus macaques during and post-ART. • Continued PD-1 modulation post-ART maintains PD-1{sup hi} cells at low levels. • Continued PD-1 modulation post-ART maintains a favorable T cell and Treg repertoire.

    Background: HIV–TB (tuberculosis) coinfection has emerged as a major public health threat. Given the multifactorial enabling environment in a resource-constrained setting like India, the consequences are of epidemic proportions. Aims: This study was aimed at identifying the clinical and epidemiological determinants underlying HIV–TB coinfection. Settings and Design: A retrospective review of patient records was done from the antiretroviral therapy center (ART) center at a district hospital in southern India between May and August 2012. Materials and Methods: Secondary data of 684 patients on ART as well as pre-ART were collected between July 2008 and June 2012 and were analyzed. Statistical Analysis: Descriptive analysis, χ2, and Wilcoxon signed rank tests were used with SPSS version 15.0 to draw significant statistical inferences. Results: HIV–TB coinfection was diagnosed in 18.9% with higher prevalence among males (75.3%), in the sexually active age group 31-45 years (61.3%), with less than primary education (44.15%), who were married (56.1%), laborers (42.4%), from rural backgrounds (88.2%), and having low income-earning capacity (94.4%). Transmission was predominantly through the heterosexual route. The key entry point was the integrated counseling and testing center (ICTC) (47.4%). Pulmonary tuberculosis (58.8%) was predominantly found followed by extrapulmonary tuberculosis (38.2%) and both in 3.1%. A favorable outcome was observed in 69.3% of coinfected patients with 89.2% on ART and 97.2% currently on DOTS therapy. The Wilcoxon signed-rank test found significant association between rises in CD4 counts after the 6th-month follow up (P < 0.05). Coinfected patients had a case fatality rate of 25%. Conclusions: The prevalence of HIV–TB coinfection recorded in this sample was 18.86%. ICTC implemented by NACO emerged as an effective entry point, while Revised National Tuberculosis Control Program referred 1.6% (n = 11) of the patients to the ART center

    Background The human immunodeficiency virus (HIV) fuels tuberculosis (TB) epidemics. In controlled clinical trials, antiretroviral therapy (ART) reduces TB incidence in HIV-infected patients. In this study we determine if, under programmatic conditions, Brazil's policy of universal ART access has impacted TB incidence among HIV-infected patients. Methods We abstracted clinical information from records of HIV-infected patients managed in the public sector in 11 Brazilian states between 1/1/1995 and 12/31/2001. Case ascertainment (TB and HIV) utilized guidelines (with added stringency) published by Brazil's Ministry of Health. We determined TB incidence and hazards ratio (HR) for ART-naïve and ART-treated [including highly active ART (HAART)] patients employing Cox proportional hazards analysis. Results Information from 463 HIV-infected patients met study criteria. The median age of the study population was 34 years, 70% were male, and mean follow-up to primary endpoints—TB, death, and last clinic visit—was 330, 1059, and 1125 days, respectively. Of the 463 patients, 76 (16%) remained ART-naïve. Of the patients who never received HAART (n = 157) 81 were treated with ART non-HAART. Of the patients who received any ART (n = 387), 306 were treated with HAART (includes those patients who later switched from ART non-HAART to HAART). Tuberculosis developed in 39/463 (8%) patients. Compared to HAART- and ART non-HAART-treated patient groups, TB incidence was 10- (p<0.001) and 2.5-fold (p = 0.03) higher in ART-naïve patients, respectively. The median baseline absolute CD4+ T-lymphocyte count for patients who developed TB was not significantly different from that of patients who remained TB free. In multivariate analysis, the incidence of TB was statistically significantly lower in HAART-treated [HR 0.2; 95% (CI 0.1, 0.6); p<0.01] compared to ART naïve patients. A baseline CD4+ T-lymphocyte count <200 cells/mm3 [HR 2.5; (95% CI 1.2, 5.4); p<0.01], prior

    Background We set out to estimate, for the three geographical regions with the highest HIV prevalence, (sub-Saharan Africa [SSA], the Caribbean and the Greater Mekong sub-region of East Asia), the human resource and economic impact of HIV on the supply of education from 2008 to 2015, the target date for the achievement of Education For All (EFA), contrasting the continuation of access to care, support and Antiretroviral therapy (ART) to the scenario of universal access. Methodology/Principal Findings A costed mathematical model of the impact of HIV and ART on teacher recruitment, mortality and absenteeism (Ed-SIDA) was run using best available data for 58 countries, and results aggregated by region. It was estimated that (1) The impact of HIV on teacher supply is sufficient to derail efforts to achieve EFA in several countries and universal access can mitigate this. (2) In SSA, the 2008 costs to education of HIV were about half of those estimated in 2002. Providing universal access for teachers in SSA is cost-effective on education returns alone and provides a return of $3.99 on the dollar. (3) The impacts on education in the hyperendemic countries in Southern Africa will continue to increase to 2015 from its 2008 level, already the highest in the world. (4) If treatment roll-out is successful, numbers of HIV positive teachers are set to increase in all the regions studied. Conclusions/Significance The return on investing in care and support is also greater in those areas with highest impact. SSA requires increased investment in teacher support, testing and particularly ART if it is to achieve EFA. The situation for teachers in the Caribbean and East Asia is similar but on a smaller scale proportionate to the lower levels of infection and greater existing access to care and support.

    Patients with human immunodeficiency virus (HIV) are living longer with their disease, as HIV has become a chronic illness managed with combination antiretroviral therapy (cART). This has led to an increasing number of patients greater than 50 years old living successfully with HIV. As the number of older adults with HIV has increased, there are special considerations for the management of HIV. Older adults with HIV must be monitored for drug side effects and toxicities. Their other non-HIV comorbidities should also be considered when choosing a cART regimen. Older adults with HIV have unique issues related to medication compliance. They are more likely than the younger HIV patients to have vision loss, cognitive impairment, and polypharmacy. They may have lower expectations of their overall health status. Depression and financial concerns, especially if they are on a fixed income, may also contribute to noncompliance in the aging HIV population. PMID:26604826

    The health of people living with HIV (PLWH) and the sustained success of antiretroviral therapy (ART) programmes depends on PLWH’s motivation and ability to self-manage the condition over the long term, including adherence to drugs on a daily basis. PLWH’s self-management of HIV and their wellbeing are likely to be interrelated. Successful self-management sustains wellbeing, and wellbeing is likely to motivate continued self-management. Detailed research is lacking on PLWH’s self-management processes on ART in resource-limited settings. This paper presents findings from a study of PLWH’s self-management and wellbeing in Wakiso District, Uganda. Thirty-eight PLWH (20 women, 18 men) were purposefully selected at ART facilities run by the government and by The AIDS Support Organisation in and around Entebbe. Two in-depth interviews were completed with each participant over three or four visits. Many were struggling economically, however the recovery of health and hope on ART had enhanced wellbeing and motivated self-management. The majority were managing their condition well across three broad domains of self-management. First, they had mobilised resources, notably through good relationships with health workers. Advice and counselling had helped them to reconceptualise their condition and situation more positively and see hope for the future, motivating their work to self-manage. Many had also developed a new network of support through contacts they had developed at the ART clinic. Second, they had acquired knowledge and skills to manage their health, a useful framework to manage their condition and to live their life. Third, participants were psychologically adjusting to their condition and their new ‘self’: they saw HIV as a normal disease, were coping with stigma and had regained self-esteem, and were finding meaning in life. Our study demonstrates the centrality of social relationships and other non-medical aspects of wellbeing for self

    Background. The impact of stigma on adherence to antiretroviral therapy (ART) has been less studied in Tanzania. Recent studies indicate that people on ART still experience stigma. Qualitative information on the subject matter is especially insufficient. Objective. This paper reports on the dimensions of stigma and discrimination and their impact on adherence to ART as experienced by people living with HIV (PLHIV). Design. A phenomenological approach was used to gather information on the lived experiences of stigma and discrimination. The sample size was determined according to the saturation principle. Results. Respondents experienced different forms of HIV-related stigma such as verbal, social, and perceived stigma. Various forms of discrimination were experienced, including relational discrimination, mistreatment by health care workers, blame and rejection by spouses, and workplace discrimination. HIV-related stigma and discrimination compromised ART adherence by reinforcing concealment of HIV status and undermining social suppport. Conclusion. After nearly a decade of increasing the provision of ART in Tanzania, PLHIV still experience stigma and discrimination; these experiences still appear to have a negative impact on treatment adherence. Efforts to reduce stigma and discrimination remain relevant in the ART period and should be given more impetus in order to maximize positive treatment outcomes. PMID:27110395

    Massive loss of lamina propria CD4(+) T cells, changes in the lymphatic architecture, and altered intestinal epithelial barrier leading to microbial translocation are the common features of HIV-1 infection and are not fully restored under combined antiretroviral therapy (cART). To better understand determinants of gut mucosal restoration, we have performed phenotypic and gene expression analyses of the gut from HIV-infected patients, naive or treated with cART initiated either at the early phase of the primary infection or later during the chronic phase. We found a depletion of T helper type 22 (Th22) and interleukin-17-producing cells in naive patients. These populations, except Th22 cells, were not restored under cART. Regulatory T cells/Th17 ratio was significantly increased in HIV-infected patients and was inversely correlated to the restoration of CD4(+) T cells but not to gut HIV DNA levels. Gene profile analysis of gut mucosal distinguished two groups of patients, which fitted with the timing of cART initiation. In their majority early, but not later treated patients, exhibited conserved intestinal lymphoid structure, epithelial barrier integrity and dendritic cell maturation pathways. Our data demonstrate that early initiation of cART helps to preserve and/or restore lymphoid gut mucosal homeostasis and provide a rationale for initiating cART during the acute phase of HIV infection.

    Grandparents throughout sub-Saharan Africa have shown immense courage and fortitude in providing care and support for AIDS-affected children. However, growing old comes with a number of challenges which can compromise the quality of care and support they are able to provide, particularly for children infected by HIV and enrolled on antiretroviral therapy (ART) programmes. For ART to be effective, and for infected children not to develop drug-resistance, a complex treatment regimen must be followed. Drawing on the perspectives of 25 nurses and eight grandparents of HIV-infected children in Manicaland, eastern Zimbabwe, we explore some of the challenges faced by grandparents in sustaining children's adherence to ART. These challenges, serving as barriers to paediatric ART, are poverty, immobility, deteriorating memory and poor comprehension of complex treatments. Although older HIV-infected children were found to play an active role in sustaining the adherence to their programme of treatment by contributing to income and food generating activities and reminding their guardians about check-ups and drug administration, such contribution was not available from younger children. There is therefore an urgent need to develop ART services that both take into consideration the needs of elderly guardians and acknowledge and enhance the agency of older children as active and responsible contributors to ART adherence.

    People living with HIV who are taking antiretroviral therapy (ART) are increasingly involved in ‘positive prevention’ initiatives. These are generally oriented to promoting abstinence, ‘being faithful’ (partner reduction) and condom use (ABC). We conducted a longitudinal qualitative study with people living with HIV using ART, who were provided with adherence education and counselling support by a Ugandan nongovernmental organisation, The AIDS Support Organisation (TASO). Forty people were selected sequentially as they started ART, stratified by sex, ART delivery mode (clinic- or home-based) and HIV progression stage (early or advanced) and interviewed at enrolment and at 3, 6, 18 and 30 months. At initiation of ART, participants agreed to follow TASO's positive-living recommendations. Initially poor health prevented sexual activity. As health improved, participants prioritised resuming economic production and support for their children. With further improvements, sexual desire resurfaced and people in relationships cemented these via sex. The findings highlight the limitations of HIV prevention based on medical care/personal counselling. As ART leads to health improvements, social norms, economic needs and sexual desires increasingly influence sexual behaviour. Positive prevention interventions need to seek to modify normative and economic influences on sexual behaviour, as well as to provide alternatives to condoms. PMID:21390948

    Over 480,000 individuals receive free antiretroviral therapy (ART) in India yet data associating ART adherence with HIV viral load for populations exclusively receiving free ART are not available. Additionally estimates of adherence using pharmacy data on ART pick-up are not available for any population in India. After 12-months ART we found self-reported estimates of adherence were not associated with HIV viral load. Individuals with < 100% adherence using pharmacy data predicted HIV viral load, and estimates combining pharmacy data and self-report were also predictive. Pharmacy adherence measures proved a feasible method to estimate adherence in India and appear more predictive of virological outcomes than self-report. Predictive adherence measures identified in this study warrant further investigation in populations receiving free ART in India to allow for identification of individuals at risk of virological failure and in need of adherence support.

    Background Long-term benefits of combination antiretroviral therapy (cART) initiation during primary HIV-1 infection are debated. Methods The evolution of plasma HIV-RNA (432 measurements) and cell-associated HIV-DNA (325 measurements) after cessation of cART (median exposure 18 months) was described for 33 participants from the Zurich Primary HIV Infection Study using linear regression and compared with 545 measurements from 79 untreated controls with clinically diagnosed primary HIV infection, respectively a known date for seroconversion. Results On average, early treated individuals were followed for 37 months (median) after cART cessation; controls had 34 months of pre-cART follow-up. HIV-RNA levels one year after cART interruption were −0.8 log10 copies/mL [95% confidence interval −1.2;−0.4] lower in early treated patients compared with controls, but this difference was no longer statistically significant by year three of follow-up (−0.3 [−0.9; 0.3]). Mean HIV-DNA levels rebounded from 2 log10 copies [1.8; 2.3] on cART to a stable plateau of 2.7 log10 copies [2.5; 3.0] attained 1 year after therapy stop, which was not significantly different from cross-sectional measurements of 9 untreated members of the control group (2.8 log10 copies [2.5; 3.1]). Conclusions The rebound dynamics of viral markers after therapy cessation suggest that early cART may indeed limit reservoir size of latently infected cells, but that much of the initial benefits are only transient. Owing to the non-randomized study design the observed treatment effects must be interpreted with caution. PMID:22102898

    The use of new potent protease inhibitor-based antiretroviral therapies in patients with human immunodeficiency virus (HIV) infection has been increasingly associated with cardiovascular risk factors, including hyperlipidaemia, fat redistribution syndrome, insulin resistance, and diabetes mellitus. The introduction of highly active antiretroviral therapy (HAART) in clinical practice has remarkably changed the natural history of HIV disease, leading to a notable extension of life expectancy, and prolonged lipid and glucose metabolism abnormalities are expected to lead to significant effects on the long-term prognosis and outcome of HIV-infected patients. Prediction modeling, surrogate markers and hard cardiovascular endpoints suggest an increased incidence of cardiovascular diseases in HIV-infected subjects receiving HAART, even though the absolute risk of cardiovascular complications remains still low, and must be balanced against the evident virological, immunological, and clinical benefits descending from combination antiretroviral therapy. Nevertheless, the assessment of cardiovascular risk should be performed on regular basis in HIV-positive individuals, especially after initiation or change of antiretroviral treatment. Appropriate lifestyle measures (including smoking cessation, dietary changes, and aerobic physical activity) are critical points, and switching HAART may be considered, although maintaining viremic control should be the main goal of therapy. Pharmacological treatment of dyslipidaemia (usually with statins and fibrates), and hyperglycaemia (with insulin-sensitizing agents and thiazolidinediones), becomes suitable when lifestyle modifications and switching therapy are ineffective or not applicable.

    Equitable access to antiretroviral therapy (ART) for men and women with human immunodeficiency virus (HIV) infection is a principle endorsed by most countries and funding bodies, including the U.S. President's Emergency Plan for AIDS (acquired immunodeficiency syndrome) Relief (PEPFAR) (1). To evaluate gender equity in ART access among adults (defined for this report as persons aged ≥15 years), 765,087 adult ART patient medical records from 12 countries in five geographic regions* were analyzed to estimate the ratio of women to men among new ART enrollees for each calendar year during 2002-2013. This annual ratio was compared with estimates from the Joint United Nations Programme on HIV/AIDS (UNAIDS)(†) of the ratio of HIV-infected adult women to men in the general population. In all 10 African countries and Haiti, the most recent estimates of the ratio of adult women to men among new ART enrollees significantly exceeded the UNAIDS estimates for the female-to-male ratio among HIV-infected adults by 23%-83%. In six African countries and Haiti, the ratio of women to men among new adult ART enrollees increased more sharply over time than the estimated UNAIDS female-to-male ratio among adults with HIV in the general population. Increased ART coverage among men is needed to decrease their morbidity and mortality and to reduce HIV incidence among their sexual partners. Reaching more men with HIV testing and linkage-to-care services and adoption of test-and-treat ART eligibility guidelines (i.e., regular testing of adults, and offering treatment to all infected persons with ART, regardless of CD4 cell test results) could reduce gender inequity in ART coverage.

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

Were evaluated and supported by their infectologists interconsultation during the period October 2008-October 2013 by depressive syndrome. Psychotherapeutic and psychiatric treatment was initiated with SSRIs and clonazepam; Neuroimaging control and biochemical laboratory studies at baseline and 2 months of treatment were conducted. In the course of psychopharmacological treatment not suffer fractures due to falls and alterations were detected in bone metabolism markers and images. He studied with endocrinology and interdisciplinary medical clinic, decided to withdraw the SSRIs with normalization of biochemical values and psychotherapeutic treatment was continued. We will raise the associations between the use of SSRIs, disturbances of bone metabolism with clinical correlation and possible drug interactions between antidepressants and antiretroviral.

    Objectives Most data on HPV and antiretroviral therapy (ART) come from high-resource countries with infrequent sampling for HPV pre- and post-ART initiation. Therefore, we examined the frequency of cervical HPV DNA detection among HIV/HSV-2 co-infected women followed monthly for 6 months both before and after initiation of ART in Rakai, Uganda. Methods Linear Array was used to detect 37 HPV genotypes in self-collected cervicovaginal swabs from 96 women who initiated ART. Random-effects log-binomial regression was used to compare the prevalence of HPV detection in the pre- and post-ART periods and determine other potential risk factors, including CD4 counts and HIV viral load. Results Nearly all women had detectable HPV in the 6 months preceding ART initiation (92%) and the cumulative prevalence remained high following initiation of therapy (90%). We found no effect of ART on monthly HPV DNA detection (prevalence ratio: 1.0; 95% confidence interval: 0.96, 1.08), regardless of immune reconstitution or HIV viral suppression. Older age and higher pre-ART CD4 counts were associated with a significantly lower risk of HPV DNA detection. Conclusions ART did not impact HPV detection within 6 months of therapy initiation, highlighting the importance of continued and consistent screening, even after ART-initiation and immune reconstitution.

    Efavirenz is the preferred nonnucleoside reverse transcriptase inhibitor (NNRTI) in first-line antiretroviral therapy (ART) regimens in low- and middle-income countries, where the prevalence of diabetes is increasing. Randomized control trials have shown mild increases in plasma glucose in participants in the efavirenz arms, but no association has been reported with overt diabetes. We explored the association between efavirenz exposure and incident diabetes in a large Southern African cohort commencing NNRTI-based first-line ART. Our cohort included HIV-infected adults starting NNRTI-based ART in a private sector HIV disease management program from January 2002 to December 2011. Incident diabetes was identified by the initiation of diabetes treatment. Patients with prevalent diabetes were excluded. We included 56,298 patients with 113,297 patient-years of follow-up (PYFU) on first-line ART. The crude incidence of diabetes was 13.24 per 1000 PYFU. Treatment with efavirenz rather than nevirapine was associated with increased risk of developing diabetes (hazard ratio 1.27 (95% confidence interval (CI): 1.10-1.46)) in a multivariate analysis adjusting for age, sex, body mass index, baseline CD4 count, viral load, NRTI backbone, and exposure to other diabetogenic medicines. Zidovudine and stavudine exposure were also associated with an increased risk of developing diabetes. We found that treatment with efavirenz, as well as stavudine and zidovudine, increased the risk of incident diabetes. Interventions to detect and prevent diabetes should be implemented in ART programs, and use of antiretrovirals with lower risk of metabolic complications should be encouraged. PMID:26945366

    Artemether-lumefantrine and nevirapine-based antiretroviral therapy (ART) are the most commonly recommended first-line treatments for malaria and HIV, respectively, in Africa. Artemether, lumefantrine, and nevirapine are metabolized by the cytochrome P450 3A4 enzyme system, which nevirapine induces, creating potential for important drug interactions. In a parallel-design pharmacokinetic study, concentration-time profiles were obtained in two groups of HIV-infected patients: ART-naïve patients and those stable on nevirapine-based therapy. Both groups received the recommended artemether-lumefantrine dose. Patients were admitted for intense pharmacokinetic sampling (0 to 72 h) with outpatient sampling until 21 days. Concentrations of lumefantrine, artemether, dihydroartemisinin, and nevirapine were determined by validated liquid chromatography-tandem mass spectrometry (LC-MS/MS) methods. The primary outcome was observed day 7 lumefantrine concentrations, as these are associated with therapeutic response in malaria. We enrolled 36 patients (32 females). Median (range) day 7 lumefantrine concentrations were 622 ng/ml (185 to 2,040 ng/ml) and 336 ng/ml (29 to 934 ng/ml) in the nevirapine and ART-naïve groups, respectively (P = 0.0002). The median artemether area under the plasma concentration-time curve from 0 to 8 h [AUC(0-8 h)] (P < 0.0001) and dihydroartemisinin AUC(60-68 h) (P = 0.01) were lower in the nevirapine group. Combined artemether and dihydroartemisinin exposure decreased over time only in the nevirapine group (geometric mean ratio [GMR], 0.76 [95% confidence interval {CI}, 0.65 to 0.90]; P < 0.0001) and increased with the weight-adjusted artemether dose (GMR, 2.12 [95% CI, 1.31 to 3.45]; P = 0.002). Adverse events were similar between groups, with no difference in electrocardiographic Fridericia corrected QT and P-R intervals at the expected time of maximum lumefantrine concentration (Tmax). Nevirapine-based ART decreased artemether and dihydroartemisinin

    Background. Cryptococcal meningitis has a high mortality in human immunodeficiency virus (HIV)-infected persons in Africa. This is preventable with early screening and preemptive therapy. We evaluated the prevalence of cryptococcal disease by antigen testing, possible associated factors, and outcomes in HIV-infected patients being managed in a tertiary hospital in Lagos, Nigeria. Methods. Sera were collected from 214 consenting HIV-infected participants with CD4+ counts <250 cells/mm3, irrespective of their antiretroviral therapy (ART) status, between November 2014 and May 2015. A cryptococcal antigen (CrAg) lateral flow assay was used for testing. Pertinent clinical data were obtained from patients and their case notes. Results. Of the 214 participants, females (124; 57.9%) outnumbered males. Mean age was 41.3 ± 9.4 (standard deviation) years. The majority (204; 95.3%) were ART experienced. The median CD4+ cell count was 160 cells/mm3 (interquartile range, 90–210). The overall seroprevalence of cryptococcal antigenemia was 8.9% (19 of 214); 6 of 61 (9.8%) in those with CD4+ cell counts <100 cells/mm3, 4 of 80 (5.0%) in the 100–200 group, and 9 of 73 (12.3%) in 200–250 cells/mm3 group. Among ART-naive patients, 1 of 10 (10%) was CrAg positive. Twenty-seven of 214 (12.6%) had associated oral thrush. Potential baseline meningitis symptoms (3 of 214 [1.4%] experienced neck pain or stiffness and 21 of 214 [9.8%] experienced headache) were common in the study group, but the result was not statistically significant in relation to CrAg positivity. Two of 19 (10.5%) CrAg-positive patients died, 10 of 19 (52.6%) were lost to follow up, and 7 of 19 (36.8%) were alive. Empirical fluconazole was routinely given to those with low CD4 counts <100 cells/mm3, which was unrelated to CrAg positivity (P = .018). Conclusions. We report a prevalence of 8.9% cryptococcal antigenemia in a setting where first-line antifungals are not readily available. We recommend Cr

We collected peripheral blood mononuclear cells from 75 adults (25 cases: HIV-infected with mitochondrial toxicity, 25 HIV-infected positive controls, and 25 HIV-negative controls). We observed statistically significant individual and group differences in ribonucleotide (RN) and deoxyribonucleotide (dRN) pools. The median RN pool was 10062 (IQR, 7090 – 12590), 4360 (IQR, 3058 –6838), and 2968 (IQR, 2538 – 4436) pmol/106 cells for negative controls, positive controls, and cases, respectively. Cases had significantly higher absolute mtDNA copy number compared to negative controls (p<0.05). Cases had significantly higher expression of Pol-γ, nucleoside transporters, cellular kinases, and ABC compared to controls. Antiretroviral therapy perturbs ribonucleotide and deoxyribonucleotide pools. Depletion of RN and dRN pools may be associated with ART-induced mitochondrial toxicity independent of Pol-γ inhibition.

    We examined the impact of antiretroviral treatment adherence among Hepatitis C co-infected HIV patients on survival and clinical outcomes. We analyzed Medicaid claims data from fourteen southern states from 2005-2007, comparing survival and clinical outcomes and cost of treatment for HIV and hepatitis-C co-infected patients (N=4,115) at different levels of adherence to antiretroviral therapy.More than one in five patients (20.5%) showed less than 50% adherence to antiretroviral treatment, but there were no racial-ethnic or gender disparities. Significant survival benefit was demonstrated at each incremental level of adherence to antiretroviral therapy (one-year mortality ranging from 3.5% in the highest adherence group to 26.0% in the lowest). Low adherence patients also had higher rates of hospitalization and emergency department visits. Relative to patients with high (>95%) ART-adherence, those with less than 25% treatment adherence had four-fold greater risk of death (adjusted odds ratio 4.22 [95% CI, 3.03,5.87]). Non-drug Medicaid expenditures were lower for high adherence patients, but cost of medications drove total Medicaid expenditures higher for high-adherence patients. Cost per quality-adjusted life year (QALY) saved (relative to the <25% low-adherence group) ranged from $21,874 for increasing adherence to 25-50% to $37,229 for increasing adherence to 75-95%. Adherence to antiretroviral therapy for patients with HIV and hepatitis C co-infection is associated with lower adverse clinical outcomes at a Medicaid cost per QALY commensurate with other well-accepted treatment and prevention strategies. Further research is needed to identify interventions which can best achieve optimal ART adherence at a population scale. PMID:25814041

    Adherence to the treatment regimen is essential to the success of highly active antiretroviral therapy for patients who are infected with HIV. The evidence suggests that poor adherence to antiretroviral drug therapy is a major problem that has the potential to diminish effective viral suppression, promote viral resistance, and place patients at risk for hospitalization, opportunistic infections, and an increased risk of HIV transmission. The primary aim of this study was to understand patients' experiences regarding their adherence to antiretroviral drug therapy. Thus, 19 participants were recruited for in-depth interviews regarding their adherence to drug regimens. All the interviews were transcribed verbatim and analyzed by using Benner's phenomenological analysis approach. Four main themes emerged from the data: (i) choosing to live and the decision to start taking medications; (ii) strategies for adhering to the regimen and managing the side-effects; (iii) relationships with healthcare providers; and (iv) advantages of the medications as a motivator to continue one's adherence to the regimen. Studying and understanding the experiences of patients can provide new insights and strategies in order to enhance patients' adherence to highly active antiretroviral therapy. PMID:21210925

    The dynamics of genital shedding of HSV-2 DNA was assessed in HIV-1-infected women taking combination antiretroviral therapy (cART). HIV-1 RNA, HIV-1 DNA and HSV DNA loads were measured during 12-18 months using frozen plasma, PBMC and cervicovaginal lavage samples from 22 HIV-1-infected women, including 17 women naive for antiretroviral therapy initiating cART and 5 women with virological failure switching to a new regimen. Nineteen (86%) women were HSV-2-seropositive. Among HSV-2-/HIV-1-co-infected women, HIV-1 RNA loads showed a rapid fall from baseline after one month of cART, in parallel in paired plasma and cervicovaginal secretions. In contrast, HIV-1 DNA loads did not show significant variations from baseline up to 18 months of treatment in both systemic and genital compartments. HSV DNA was detected at least once in 12 (63%) of 19 women during follow up: HSV-2 shedding in the genital compartment was observed in 11% of cervicovaginal samples at baseline and in 16% after initiating or switching cART. Cervicovaginal HIV-1 RNA loads were strongly associated with plasma HIV-1 RNA loads over time, but not with cervicovaginal HSV DNA loads. Reactivation of genital HSV-2 replication frequently occurred despite effective cART in HSV-2-/HIV-1-co-infected women. Genital HSV-2 replication under cART does not influence cervicovaginal HIV-1 RNA or DNA shedding. PMID:25769886

    Background This article presents part of the findings from a larger study that sought to assess the role that gender relations play in influencing equity regarding access and adherence to antiretroviral therapy (ART). Review of the literature has indicated that, in Southern and Eastern Africa, fewer men than women have been accessing ART, and the former start using ART late, after HIV has already been allowed to advance. The main causes for this gender gap have not yet been fully explained. Objective To explore how masculinity norms limit men's access to ART in Dar es Salaam. Design This article is based on a qualitative study that involved the use of focus group discussions (FGDs). The study employed a stratified purposive sampling technique to recruit respondents. The study also employed a thematic analysis approach. Results Overall, the study's findings revealed that men's hesitation to visit the care and treatment clinics signifies the superiority norm of masculinity that requires men to avoid displaying weakness. Since men are the heads of families and have higher social status, they reported feeling embarrassed at having to visit the care and treatment clinics. Specifically, male respondents indicated that going to a care and treatment clinic may raise suspicion about their status of living with HIV, which in turn may compromise their leadership position and cause family instability. Because of this tendency towards ‘hiding’, the few men who register at the public care and treatment clinics do so late, when HIV-related signs and symptoms are already far advanced. Conclusion This study suggests that the superiority norm of masculinity affects men's access to ART. Societal expectations of a ‘real man’ to be fearless, resilient, and emotionally stable are in direct conflict with expectations of the treatment programme that one has to demonstrate health-promoting behaviour, such as promptness in attending the care and treatment clinic, agreeing to take

    Background Since antiretroviral therapy (ART) became available in the developed world, the prevalence of unprotected sex and the incidence of sexually transmitted infections (STIs) and HIV have increased. We hypothesized that a similar phenomenon may be occurring in sub-Saharan Africa concomitant with the scale-up of HIV treatment. Methods We conducted a general population-based survey in Kisumu, Kenya. Participants completed an interview that included demographics as well as ART-related attitudes and beliefs (AB) and then underwent HIV serological testing. Exploratory and confirmatory factor analyses of AB about ART indicated two factors: 1) ART-related risk compensation (increased sexual risk taking now that ART is available); and 2) a perception that HIV is more controllable now that ART is available. Logistic regression was used to determine associations of these factors with HIV-seroprevalence after controlling for age. Findings 1,655 (90%) of 1,844 people aged 15–49 contacted, including 749 men and 906 women, consented to participate in the study. Most participants (n = 1164; 71%) had heard of ART. Of those who had heard of ART, 23% believed ART was a cure for HIV. ART-related risk compensation (Adjusted (A)OR = 1.45, 95% CI 1.16–1.81), and a belief that ART cures HIV (AOR = 2.14, 95% CI 1.22–3.76) were associated with an increased HIV seroprevalence in men but not women after controlling for age. In particular, ART-related risk compensation was associated with an increased HIV-seroprevalence in young (aged 15–24 years) men (OR = 1.56; 95% CI 1.12–2.19). Conclusions ART-related risk compensation and a belief that ART cures HIV were associated with an increased HIV seroprevalence among men but not women. HIV prevention programs in sub-Saharan Africa that target the general population should include educational messages about ART and address the changing beliefs about HIV in the era of greater ART availability.

    We measured cell-associated human immunodeficiency virus (HIV)-1 DNA (CAD) and RNA (CAR) and plasma HIV-1 RNA in blood samples from 20 children in the Children with HIV Early Antiretroviral (CHER) cohort after 7-8 years of suppressive combination antiretroviral therapy (cART). Children who initiated cART early (<2 months; n = 12) had lower HIV-1 CAD (median, 48 vs 216; P < .01) and CAR (median, 5 vs 436; P < .01) per million peripheral blood mononuclear cells than children who started later (≥ 2 months; n = 8). Plasma HIV-1 RNA levels were not significantly lower in early-treated children (0.5 vs 1.2 copies/mL; P = .16). Early treatment at <2 months of age reduces the number of HIV-infected cells and HIV CAR. PMID:25538273

    Abstract Availability of integrase strand transfer inhibitors created interest in determining whether their use would decrease persistently infected cell numbers. This study hypothesized that adding raltegravir (RAL) to standard antiretroviral therapy (ART) would decrease human immunodeficiency virus (HIV)-infected CD4+ T cells more than standard combination ART. This was a pilot, randomized study comparing open-label standard triple ART to standard triple ART plus RAL over 96 weeks in ART-naive adults with early HIV infection. The primary objective was to compare quantity and trajectory of HIV DNA. Eighty-two persons were referred. A diverse set of reasons precluded the enrollment of all but 10. Those who enrolled and completed the study had an estimated median duration of HIV infection of 74 days at ART start. The groups had similar baseline characteristics. The RAL group had more rapid first phase plasma HIV RNA decay (0.67 log10 copies/mL/day) than with combination ART (0.34 log10copies/mL/day), p = 0.037. Second phase HIV RNA decay, residual viremia, cell-associated RNA, HIV DNA, CD4+ T-cells with replication-competent virus, and 2LTR circle levels did not differ between groups. Among those with entry plasma HIV RNA levels above the median, 2LTR circles were significantly lower over time than in those with lower entry HIV RNA levels (p = 0.02). Our results suggest homogeneity of responses in cell-associated RNA, HIV DNA, CD4+ T-cells with replication-competent virus, and 2LTR circles with early HIV in both ART groups. The kinetics of 2LTR DNA did not reflect the kinetics of plasma HIV RNA decline following ART initiation. PMID:26862469

    Objective: To increase equitable access to life insurance for HIV-positive individuals by identifying subgroups with lower relative mortality. Design: Collaborative analysis of cohort studies. Methods: We estimated relative mortality from 6 months after starting antiretroviral therapy (ART), compared with the insured population in each country, among adult patients from European cohorts participating in the ART Cohort Collaboration (ART-CC) who were not infected via injection drug use, had not tested positive for hepatitis C, and started triple ART between 1996–2008. We used Poisson models for mortality, with the expected number of deaths according to age, sex and country specified as offset. Results: There were 1236 deaths recorded among 34 680 patients followed for 174 906 person-years. Relative mortality was lower in patients with higher CD4 cell count and lower HIV-1 RNA 6 months after starting ART, without prior AIDS, who were older, and who started ART after 2000. Compared with insured HIV-negative lives, estimated relative mortality of patients aged 20–39 from France, Italy, United Kingdom, Spain and Switzerland, who started ART after 2000 had 6-month CD4 cell count at least 350 cells/μl and HIV-1 RNA less than104 copies/ml and without prior AIDS was 459%. The proportion of exposure time with relative mortality below 300, 400, 500 and 600% was 28, 43, 61 and 64%, respectively, suggesting that more than 50% of patients (those with lower relative mortality) could be insurable. Conclusion: The continuing long-term effectiveness of ART implies that life insurance with sufficiently long duration to cover a mortgage is feasible for many HIV-positive people successfully treated with ART for more than 6 months.

    The association of gender with the treatment outcome during long-term antiretroviral therapy (ART) in human immunodeficiency virus (HIV)-infected patients has been controversial. Here, we performed a comparative proteomic analysis of peripheral blood mononuclear cells (PBMC) by using a label-free shotgun method with nano-LC-MS/MS to investigate the gender differences in responses to long-term ART. This analysis enrolled 30 HIV-infected patients (16 males and 14 females), as well as 20 healthy adults (10 males and 10 females) as control. Quantitative real-time RT-PCR and immunoblotting were used to validate the results of proteomic approach. A total of 53 proteins showing differential expression (± 1.5 fold, p < 0.05) were identified in HIV-infected patients versus healthy adults. Of these proteins, 22 proteins showed identical regulation patterns in both men and women, while 31 proteins were gender-specific (21 men-specific and 10 women-specific proteins). Bioinformatics analysis indicated that long-term ART causes up-regulation of apoptosis, oxidative phosphorylation and mitochondrial dysfunction while down-regulation of oxidative stress and immune system process in men compared to women. These findings point to a concept that gender has a significant influence on the outcomes of ART at protein level and women present a potential favorable immunological pattern and recovery during long-term ART.

    In this article, we examine how people living with HIV (PLWH) were able to reconceptualize or "reframe" their understanding of HIV and enhance their capacity to self-manage the condition. Two in-depth interviews were held with 38 PLWH (20 women, 18 men) selected from three government and nongovernment antiretroviral therapy (ART) delivery sites in Wakiso District, and the narratives analyzed. ART providers played an important role in shaping participants' HIV self-management processes. Health workers helped PLWH realize that they could control their condition, provided useful concepts and language for emotional coping, and gave advice about practical self-management tasks, although this could not always be put into practice. ART providers in this setting were spaces for the development of a collective identity and a particular form of therapeutic citizenship that encouraged self-management, including adherence to ART. Positive framing institutions are important for many PLWH in resource-limited settings and the success of ART programs. PMID:26246523

    Abstract Autoimmune manifestations are common in human immunodeficiency virus (HIV) patients. However, the autoantibody spectrum associated with HIV infection and the impact of antiretroviral therapy (ART) remains to be determined. The plasma autoantibody spectrum for HIV patients was characterized by protein microarrays containing 83 autoantigens and confirmed by enzyme-linked immunosorbent assay (ELISA). Regulatory T cells (Tregs) and myeloid-derived suppressor cells (MDSCs) were analyzed by flow cytometry and their effects on autoantibodies production were determined by B cell ELISpot. Higher levels of autoantibody and higher prevalence of elevated autoantibodies were observed in ART-naive HIV patients compared to healthy subjects and HIV patients on ART. The highest frequency of CD33+CD11b+HLA-DR+ cells was observed in ART-naive HIV patients and was associated with the quantity of elevated autoantibodies. In addition, CD33+CD11b+HLA-DR+ cells other than Tregs or MDSCs boost the B cell response in a dose-dependent manner by in vitro assay. In summary, HIV infection leads to elevation of autoantibodies while ART suppresses the autoimmune manifestation by decreasing CD33+CD11b+HLA-DR+ cells in vivo. The roles of CD33+CD11b+HLA-DR+ cells on disease progression in HIV patients needs further assessment. PMID:27082567

    Background Initiation of combination antiretroviral therapy (ART) results in higher total CD4 cell counts, a surrogate for immune reconstitution. Whether the baseline CD4 cell count affects reconstitution of immune cell subsets has not been well characterized. Methods Using data from 978 patients (621 with comprehensive immunological assessments) from the AIDS [Acquired Immunodeficiency Syndrome] Clinical Trials Group protocol 384, a randomized trial of initial ART, we compared reconstitution of CD4+, CD4+ naive and memory, CD4+ activation, CD8+, CD8+ activation, B, and natural killer cells among patients in different baseline CD4+ strata. Reference ranges for T cell populations in control patients negative for human immunodeficiency virus (HIV) infection were calculated using data from AIDS Clinical Trials Group protocol A5113. Results Patients in the lower baseline CD4+ strata did not achieve total CD4+ cell counts similar to those of patients in the higher strata during 144 weeks of ART, although CD4+ cell count increases were similar. Ratios of CD4+ naive-memory cell counts and CD4+:CD8+ cell counts remained significantly reduced in patients with lower baseline CD4+ cell counts (≤350 cells/mm3). These immune imbalances were most notable for those initiating ART with a baseline CD4+ cell count ≤200 cells/mm3, even after adjustment for baseline plasma HIV RNA levels. Conclusions After nearly 3 years of ART, T cell subsets in patients with baseline CD4+ cell counts >350 cells/mm3 achieved or approached the reference range those of control individuals without HIV infection. In contrast, patients who began ART with ≤350 CD4+ cells/mm3 generally did not regain normal CD4+ naive-memory cell ratios. These results support current guidelines to start ART at a threshold of 350 cells/mm3 and suggest that there may be immunological benefits associated with initiating therapy at even higher CD4+ cell counts.

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

    The aim of this study was to evaluate and compare the effect of two types of exercises interventions on the regularity and health-related physical fitness in HIV-infected individuals who use antiretroviral therapy (ART). A total of 53 HIV+ African women (mean age=39.5±8.4 years) on ART participated in the study. Subjects were randomly divided into 3 groups, namely, formal exercise (FEG), playful exercise (PEG) and control (CG). During 12 weeks, the exercise groups underwent a program of 1-hour duration with a frequency of 3 times a week. The FEG performed a protocol that included 20 minutes of exercise, cycling at 60 % of V̇O2peak, increasing to 75 % and 85 % in the 4th and 8th weeks, respectively, and a muscular endurance circuit consisted of 6 exercises at 15 repetitions per minute (RM). The PEG followed a program consisting of active games. Before and after the intervention the participants were submitted to a clinical evaluation including immunological parameters (CD4+), cardiovascular risk factors, physical fitness and anthropometry. Comparison of somatic variables before and after the program showed no exercise effect. Immunological and cardiovascular variables were also independent of the exercise group. The main effect was found in cardiorespiratory fitness: exercise groups increased significantly in V̇O2peak (FEG=14.7 %; PEG=11.1 %) with no significant differences in CG. The percentage of high attendance was identical between the two groups. It was concluded that there is no contraindication for exercise in this type of population and the beneficial effect was mainly in cardiorespiratory fitness, regardless of the type of exercise performed.

For youth living with HIV, adherence to life-saving treatment regimens are likely to be affected by the complex set of economic and social circumstances that challenge their families and also exacerbate health problems. Using baseline data from the National Institute of Child and Human Development (NICHD) funded Suubi+Adherence study, we examined the extent to which individual and composite measures of equity predict self-reported adherence among Ugandan adolescents aged 10-16 (n = 702) living with HIV. Results showed that greater asset ownership, specifically familial possession of seven or more tangible assets, was associated with greater odds of self-reported adherence (OR 1.69, 95% CI: 1.00-2.85). Our analyses also indicated that distance to the nearest health clinic impacts youth's adherence to an ARV regimen. Youth who reported living nearest to a clinic were significantly more likely to report optimal adherence (OR 1.49, 95% CI: 0.92-2.40). Moreover, applying the composite equity scores, we found that adolescents with greater economic advantage in ownership of household assets, financial savings, and caregiver employment had higher odds of adherence by a factor of 1.70 (95% CI: 1.07-2.70). These findings suggest that interventions addressing economic and social inequities may be beneficial to increase antiretroviral therapy (ART) uptake among economically vulnerable youth, especially in sub-Saharan Africa. This is one of the first studies to address the question of equity in adherence to ART among economically vulnerable youth with HIV. PMID:27392003

    PENTA Guidelines aim to provide practical recommendations for treating children with HIV infection in Europe. Changes to guidance since 2004 have been informed by new evidence and by expectations of better outcomes following the ongoing success of antiretroviral therapy (ART). Participation in PENTA trials of simplifying treatment is encouraged. The main changes are in the following sections: 'When to start ART': Treatment is recommended for all infants, and at higher CD4 cell counts and percentages in older children, in line with changes to adult guidelines. The number of age bands has been reduced to simplify and harmonize with other paediatric guidelines. Greater emphasis is placed on CD4 cell count in children over 5 years, and guidance is provided where CD4% and CD4 criteria differ. 'What to start with': A three-drug regimen of two nucleoside reverse transcriptase inhibitors (NRTIs) with either a nonnucleoside reverse transcriptase inhibitor (NNRTI) or a boosted protease inhibitor (PI) remains the first choice combination. Lamivudine and abacavir are the NRTI backbone of choice for most children, based on long-term follow-up in the PENTA 5 trial. Stavudine is no longer recommended. Whether to start with an NNRTI or PI remains unclear, but PENPACT 1 trial results in 2009 may help to inform this. All PIs should be ritonavir boosted. Recommendations on use of resistance testing, therapeutic drug monitoring and HLA testing draw from data in adults and from European paediatric cohort studies. Recently updated US and WHO paediatric guidelines provide more detailed review of the evidence base. Differences between guidelines are highlighted and explained. PMID:19878352

    Recent studies have documented dramatic decreases in opportunistic infections, hospitalizations, and mortality among HIV-infected persons, owing primarily to the advent of highly active antiretroviral medications. Unfortunately, not all segments of the population living with HIV benefit equally from treatment. In San Francisco, only about 30% of the HIV-infected urban poor take combination highly active antiretroviral medications, as compared with 88% of HIV-infected gay men. Practitioners who care for the urban poor are reluctant to prescribe these medications, fearing inadequate or inconsistent adherence to the complicated medical regimen. Persons typically must take 2 to 15 pills at a time, 2 to 3 times a day. Some of the medications require refrigeration, which may not be available to the homeless poor. Most homeless persons do not have food available to them on a consistent schedule. Therefore, they may have difficulty adhering to instructions to take medications only on an empty stomach or with food. Lack of a safe place to store medications may be an issue for some. In addition, many urban poor live with drug, alcohol, or mental health problems, which can interfere with taking medications as prescribed. Inconsistent adherence to medication regimens has serious consequences. Patients do not benefit fully from treatments, and they will become resistant to the medications in their regimen as well as to other medications in the same classes as those in their regimen. Development of resistance has implications for the broader public health, because inadvertent transmission of multidrug-resistant strains of HIV has been demonstrated. Concern that the urban poor will not adhere to highly active antiretroviral medication regimens has led to debate on the role of clinicians and public health officials in determining who can comply with these regimens. Rather than define the characteristics that would predict adherence to these regimens, the San Francisco Department

    Human immunodeficiency virus (HIV)-associated multicentric Castleman disease (MCD) is a lymphoproliferation associated with human herpes virus-8 (HHV-8). Optimal treatment in patients not responding to antiretroviral therapy (ART) is undefined. We report 12 patients with ART refractory HIV-MCD. Patients with HIV-MCD were identified and baseline characteristics, treatment and outcome considered. Median CD4 count at HIV-MCD diagnosis was 295 (60-950) cells/mL. All patients had waxing and waning systemic symptoms, lymphadenopathy and/or splenomegaly, with non-Hodgkin lymphoma (NHL) in three. Treatment included: anti-HHV-8 therapy, n = 8; alone, n = 4; with systemic chemotherapy (CT) ± immunotherapy (IT), n = 4; CT ± IT only, n = 2. Initial median HHV-8 viral load (VL) was 7 × 10(4) copies/mL and at follow-up < 40 in 6/7 survivors; and 403-7.2 × 10(6) in 4/5 who died. One patient developed NHL despite an HHV-8 VL < 40. HIV-MCD is challenging to treat. Suppression of plasma HHV-8 VL did not prevent development of NHL. Anti-HHV-8 therapy should probably be considered adjunctive to cytotoxic therapies. PMID:25093377

    Directly observed therapy (DOT) for human immunodeficiency virus (HIV) infection is commonly used in correctional settings; however, the efficacy of DOT for treating HIV infection has not been determined. We prospectively assessed adherence to antiretroviral therapy regimens among 31 HIV-infected prison inmates who were receiving >or=1 antiretrovirals via DOT. Adherence was measured by self-report, pill count, electronic monitoring caps, and, for DOT only, medication administration records. Overall, median adherence was 90%, as measured by pill count; 86%, by electronic monitoring caps; and 100%, by self-report. Adherence, as measured by electronic monitoring caps, was >90% in 32% of the subjects. In 91% of cases, adherence, as measured by medication administration records, was greater than that recorded by electronic monitoring caps for the same medications administered by DOT. Objective methods of measurement revealed that adherence to antiretroviral regimens administered wholly or in part by DOT was antiretroviral therapy. PMID:12802758

    In the past 15 years, improvements in the management of HIV infection have dramatically reduced morbidity and mortality. Similarly, rapid advances in antiretroviral medications have resulted in the possibility of life-long therapy with simple and tolerable regimens. Protease inhibitors have been important medications in regimens of combination antiretroviral therapy for the treatment of HIV. One of the recommended and commonly used therapies in this class is once-daily-administered atazanavir, pharmacologically boosted with ritonavir (atazanavir/r). Clinical studies and practice have shown these drugs, in combination with other antiretroviral agents, to be potent, safe and easy to use in a variety of settings. Atazanavir/r has minimal short-term toxicity, including benign bilirubin elevation, and has less potential for long-term complications of hyperlipidemia and insulin resistance compared with other protease inhibitors. A high genetic barrier to resistance and a favorable resistance profile make it an excellent option for initial HIV treatment or as the first drug utilized in the protease inhibitors class. Atazanavir/r is also currently being studied in novel treatment strategies, including combinations with new classes of antiretrovirals to assess nucleoside reverse transcriptase inhibitor-sparing regimens. In this article we review atazanavir/r as a treatment for HIV infection and discuss the latest information on its pharmacology, efficacy and toxicity. PMID:21731578

  7. Asymptomatic HIV-infected Individuals on Antiretroviral Therapy Exhibit Impaired Lung CD4+ T-Cell Responses to Mycobacteria

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

    Background. Persistent aminotransferase elevations are common in human immunodeficiency virus (HIV)–infected patients on antiretroviral therapy (ART), including those without hepatitis B or C coinfection, but their clinical significance is unknown. Methods. HIV-infected adults with aminotransferase levels elevated above the upper limit of normal for ≥6 months while receiving ART, and without chronic viral hepatitis or other known causes of chronic liver disease, underwent a detailed metabolic assessment and liver biopsy. Results. Sixty-two HIV-infected subjects completed the study. Forty (65%) had clinically significant liver pathology, including 34 (55%) with nonalcoholic steatohepatitis (NASH) and 11 (18%) with bridging fibrosis, 10 of whom also had NASH. Nonspecific abnormalities alone were seen in 22 (35%) subjects, including mild steatosis, mild to moderate inflammation, and evidence of drug adaptation. Insulin resistance, obesity, and the presence of either of 2 minor alleles in the PNPLA3 gene were significantly associated with increased risk of NASH and fibrosis. NASH and/or fibrosis were not associated with duration of HIV infection or ART, specific antiretroviral drugs, history of opportunistic infection, immune status, or duration of aminotransferase elevation. Conclusions. HIV-infected adults with chronic aminotransferase elevations while receiving ART have a high rate of liver disease. Noninvasive testing can help identify liver disease in such patients, but liver biopsy is necessary to definitively identify those at risk for liver disease progression and complications. Longitudinal follow-up of this cohort will better characterize the natural history of aminotransferase elevations in this population and identify noninvasive biomarkers of liver disease progression.

    Background A major challenge to HIV eradication strategies is the lack of an accurate measurement of the total burden of replication-competent HIV (the “reservoir”). We assessed the association of anti-HIV antibody responses and the estimated size of the reservoir during antiretroviral therapy (ART). Methods We evaluated anti-HIV antibody profiles using luciferase immunoprecipitation systems (LIPS) assay in relation to several blood-based HIV reservoir measures: total and 2-LTR DNA (rtPCR or droplet digital PCR); integrated DNA (Alu PCR); unspliced RNA (rtPCR), multiply-spliced RNA (TILDA), residual plasma HIV RNA (single copy PCR), and replication-competent virus (outgrowth assay). We also assessed total HIV DNA and RNA in gut-associated lymphoid tissue (rtPCR). Spearman correlations and linear regressions were performed using log-transformed blood- or tissue-based reservoir measurements as predictors and log-transformed antibody levels as outcome variables. Results Among 51 chronically HIV-infected ART-suppressed participants (median age = 57, nadir CD4+ count = 196 cells/mm3, ART duration = 9 years), the most statistically significant associations were between antibody responses to integrase and HIV RNA in gut-associated lymphoid tissue (1.17 fold-increase per two-fold RNA increase, P = 0.004) and between antibody responses to matrix and integrated HIV DNA in resting CD4+ T cells (0.35 fold-decrease per two-fold DNA increase, P = 0.003). However, these associations were not statistically significant after a stringent Bonferroni-adjustment of P<0.00045. Multivariate models including age and duration of ART did not markedly alter results. Conclusions Our findings suggest that anti-HIV antibody responses may reflect the size of the HIV reservoir during chronic treated HIV disease, possibly via antigen recognition in reservoir sites. Larger, prospective studies are needed to validate the utility of antibody levels as a measure of the total body burden of HIV

    Abstract Our objective was to determine tuberculosis (TB) incidence and evaluate TB risk in adults after one or more years of use of combination antiretroviral therapy (cART) through a retrospective cohort study in Jos, Nigeria. We studied a cohort of HIV-infected adults treated with ART for at least 1 year. Based on immunologic and virologic responses to ART, patients were categorized into four groups: CD4 T cell count ≥350 cells/mm3 and HIV-1 RNA level ≤400 copies/ml (group 1), CD4 T cell count ≥350 cells/mm3 and HIV-1 RNA level >400 copies/ml (group 2), CD4 T cell count <350 cells/mm3 and HIV-1 RNA level ≤400 copies/ml (group 3), and CD4 T cell count <350 cells/mm3 and HIV-1 RNA level >400 copies/ml (group 4). Time to incident TB for the four groups was analyzed using the Kaplan–Meier method. Cox regression models were used to evaluate predictors of incident TB. In this cohort of 5,093 HIV-infected adults, of which 68.4% were female, with a mean age 35.1 years (standard deviation 9.1 years), we observed 98 cases of incident TB during 4 years and 3 months of follow-up. The overall TB incidence rate was 8.7 cases/1,000 patient-years of follow-up. Adjusted hazards for incident TB were 2.11 (95% CI 0.97–4.61), 2.05 (95% CI 1.10–3.79), and 3.65 (95% CI 1.15–5.06) in group 2, 3, and 4 patients, respectively, compared to group 1. Tuberculosis incidence in patients on ART is driven by poor immunologic and/or virologic response. Optimization of HIV treatment should be prioritized to reduce the burden of TB in this high-risk population. PMID:23316724

    Introduction Antiretroviral therapy (ART) prevents HIV transmission within HIV serodiscordant couples (SDCs), but slow implementation and low uptake has limited its impact on population-level HIV incidence. Home HIV testing and counselling (HTC) campaigns could increase ART uptake among SDCs by incorporating couples’ testing and ART referral. We estimated the reduction in adult HIV incidence achieved by incorporating universal ART for SDCs into home HTC campaigns in KwaZulu-Natal (KZN), South Africa, and southwestern (SW) Uganda. Methods We constructed dynamic, stochastic, agent-based network models for each region. We compared adult HIV incidence after 10 years under three scenarios: (1) “Current Practice,” (2) “Home HTC” with linkage to ART for eligible persons (CD4 <350) and (3) “ART for SDCs” regardless of CD4, delivered alongside home HTC. Results ART for SDCs reduced HIV incidence by 38% versus Home HTC: from 1.12 (95% CI: 0.98–1.26) to 0.68 (0.54–0.82) cases per 100 person-years (py) in KZN, and from 0.56 (0.50–0.62) to 0.35 (0.30–0.39) cases per 100 py in SW Uganda. A quarter of incident HIV infections were averted over 10 years, and the proportion of virally suppressed HIV-positive persons increased approximately 15%. Conclusions Using home HTC to identify SDCs and deliver universal ART could avert substantially more new HIV infections than home HTC alone, with a smaller number needed to treat to prevent new HIV infections. Scale-up of home HTC will not diminish the effectiveness of targeting SDCs for treatment. Increasing rates of couples’ testing, disclosure, and linkage to care is an efficient way to increase the impact of home HTC interventions on HIV incidence. PMID:27174911

    Since 2001, antiretroviral therapy (ART) has been available for people living with HIV (PLHIV) in Lao People's Democratic Republic (PDR). Over 10 years of the ART program many HIV patients were found with advanced-stage AIDS in health care service facilities. This study aimed to examine factors associated with delayed access to ART among PLHIV in the capital of Vientiane. A cross-sectional study was conducted with 283 respondents (131 males and 152 females) aged 15 years or over. In this study, delayed access to ART was defined by a CD4 cell count of less than 350 cells/mm(3) at the first screening, or those who presented with advanced AIDS-related symptoms. The odds ratios (ORs) and 95% confidence intervals (CIs) were estimated by a logistic model. After adjustment, young people (OR=2.17; 95% CI: 1.00-4.68; p=0.049), low education (OR=0.23; 95% CI: 0.10-0.55; p=0.001) and duration between risk behavior and HIV test (OR=3.83; 95% CI: 1.22-12.00; p=0.021) were significantly associated with delayed access to ART. Low perception of high risk behaviors was one of the obstacles leading to delayed testing and inability to access ART. Almost all reported feeling self-stigma, and only 30.5% of men and 23.7% of women disclosed the HIV status to his/her partner/spouse. In conclusion, delayed access to ART was associated with individual factors and exposure to health care facility. In order to improve early detection HIV infection following access to ART, an improvement in perceptional knowledge of HIV, as well as reduction of HIV/AIDS-related stigma, might be needed.

Eligible patients enrolled in the clinic during the period 1999–2013 were classified into two groups: those referred to a clinic-based HIV pharmacist for initiation of ART (the PAM group) and those managed by a primary care provider (the control group). The primary study objective was the median time to viral suppression; secondary objectives included the durability of response to the first ART regimen. Relative hazards for the events of interest were estimated using a marginal structural Cox proportional hazards model and Kaplan–Meier curves, with inverse probability weights used to control for selection and confounding bias. Results Patients referred for PAM services (n = 819) typically had higher baseline viral loads and lower CD4+ cell counts than those in the control group (n = 436). The likelihood of viral suppression during the first two years after ART initiation was significantly higher in the PAM group versus the control group (hazard ratio, 1.37; 95% confidence interval, 1.18–1.59; p < 0.0001). The median durability of the first ART regimen was 100 months in the PAM group versus 44 months in the control group (p > 0.05). Conclusion In treatment-naive patients, suppression of HIV viral load occurred earlier when pharmacists assisted with initiating ART than when ART was initiated without that assistance.

    Background On January 12, 2010, a devastating 7.0 magnitude earthquake struck the West Department of Haiti, killing more than 200,000 people and injuring or displacing many more. This disaster threatened continuity of HIV care and treatment services. Objectives This case study examined the effect of the devastating 2010 earthquake in Haiti on attrition from the HIV antiretroviral therapy (ART) program. Design The study triangulated retrospective data from existing sources, including: 1) individual-level longitudinal patient data from an electronic medical record for ART patients at two large public sector departmental hospitals differently affected by the earthquake; and 2) aggregate data on the volume of HIV-related services delivered at the two hospitals before and after the earthquake. Methods The study compared ART attrition and service delivery in Jacmel, a site in the ‘very strong’ zone of earthquake impact, and in Jérémie, a site in the ‘light’ zone of earthquake impact. The analysis used time-to-event analysis methods for the individual-level patient data, and descriptive statistical methods for the aggregate service delivery data. Results Adjusted ART attrition risk was lower at the hospital in Jacmel after vs. before the earthquake (HR=0.51; p=0.03), and was lower in Jacmel vs. Jérémie both before (HR=0.55; p=0.01) and after the earthquake (HR=0.35; p=0.001). The number of new ART patient enrollments, new HIV patient registrations, and HIV clinical visits dropped notably in Jacmel immediately after the earthquake, but then rapidly rebounded. On average, there was no change in new ART enrollments per month after vs. before the earthquake at either site. Conclusion These findings underscore the resilience of Haitian ART providers and patients, and contribute evidence that it is possible to maintain continuity of ART services even in the context of a complex humanitarian crisis.

    Objective: HIV-infected adults have high rates of pneumococcal carriage and invasive disease. We investigated the effect of antiretroviral therapy (ART) on pneumococcal carriage in HIV-infected adults prior to infant pneumococcal conjugate vaccine (PCV) rollout. Design: Observational cohort study. Methods: We recruited HIV-infected adults newly attending a rural HIV clinic in northern Malawi between 2008 and 2010. Nasopharyngeal samples were taken at baseline and after 6, 12, 18 and 24 months. We compared pneumococcal carriage by ART status using generalized estimated equation models adjusted for CD4+ cell count, sex, seasonality, and other potential confounders. Results: In total, 336 individuals were included, of which 223 individuals started ART during follow-up. Individuals receiving ART had higher pneumococcal carriage than individuals not receiving ART (25.9 vs. 19.8%, P = 0.03) particularly for serotypes not included in PCV13 (16.1 vs. 9.6% P = 0.003). Following adjustment, increased carriage of non-PCV13 serotypes was still observed for individuals on ART, but results for all serotypes were nonsignificant [all serotypes: adjusted risk ratio (aRR) 1.22 (0.95–1.56); non-PCV13 serotypes: aRR 1.72, 95% CI 1.13–2.62]. Conclusion: Pneumococcal carriage in HIV-infected adults in Malawi remained high despite use of ART, consistent with failure of mucosal immune reconstitution in the upper respiratory tract. There was evidence of increased carriage of non-PCV13 serotypes. HIV-infected adults on ART could remain an important reservoir for pneumococcal diversity post infant pneumococcal vaccine introduction. Control of pneumococcal disease in African HIV remains a priority. PMID:26218599

    Objective We aimed to perform a systematic review and meta-analysis examining the impact of TB treatment at the time of combination antiretroviral therapy (cART) initiation on subsequent mortality. Methods We searched PubMed, EMBASE, and selected conference proceedings for studies that report adult mortality on cART, stratified by TB treatment status at cART initiation. Stratified random-effects and meta-regression analyses were used to examine the influence of study and population characteristics. Results 22 eligible cohort studies reported data on 98,350 (range 74-15,225) adults, of whom 14,779 (15%) were receiving TB treatment at cART initiation. Studies of those receiving vs. not receiving TB treatment had an average mortality relative risk of 1.10 (95% confidence interval 0.87-1.40) at 1-3 months (based upon 8 estimates), 1.15 (0.94-1.41) at 6-12 months (11 estimates), and 1.33 (1.02-1.75) at 18-98 months (10 estimates) following cART initiation. However, there was a wide range of estimates and those at later time points were markedly heterogeneous. Meta-regression identified factors associated with elevated average risk estimates: lower median baseline CD4 counts and adjustment for baseline hemoglobin at 1-3 months; longer length of follow-up and women-only studies at 6-12 months; and not adjusting for BMI/weight at 18-98 months. Conclusions Patients receiving TB treatment at cART initiation did not have a statistically significant estimated increase in short-term risk of all-cause mortality as compared to those not receiving TB treatment. TB treatment was significantly associated with increased mortality after about a year of cART, suggesting that patients with concurrent TB treatment at cART initiation may benefit from continued support after TB treatment completion.

    Background The primary objectives of this study were to determine the association between alcohol and antiretroviral therapy (ART) adherence and the perceived appropriateness and acceptability of elements of an adherence counseling program with a focus on alcohol-related ART nonadherence among a sample of ART recipients in human immunodeficiency virus (HIV) clinics in Tshwane, South Africa. Methods We conducted a cross-sectional study with purposive sampling. The sample comprised 304 male and female ART recipients at two President’s Emergency Plan For AIDS Relief-supported HIV clinics. Using an interview schedule, we assessed patients’ alcohol use (Alcohol Use Disorders Identification Test), other drug use, level of adherence to ART, and reasons for missing ART doses (AIDS Clinical Trials Group adherence instrument). Additionally, patients’ views were solicited on: the likely effectiveness of potential facilitators; the preferred quantity, duration, format, and setting of the sessions; the usefulness of having family members/friends attend sessions along with the patient; and potential skill sets to be imparted. Results About half of the male drinkers’ and three quarters of the female drinkers’ Alcohol Use Disorders Identification Test scores were suggestive of hazardous or harmful drinking. Average self-reported ART adherence was 89.7%. There was a significant association between level of alcohol use and degree of ART adherence. Overall, participants perceived two clinic-based sessions, each of one hour’s duration, in a group format, and facilitated by a peer or adherence counselor, as most appropriate and acceptable. Participants also had a favorable attitude towards family and friends accompanying them to the sessions. They also favored an alcohol-focused adherence counseling program that employs motivational interviewing and cognitive behavioral therapy-type approaches. Conclusion The association between alcohol use and ART nonadherence points to a

    Background High rates of patient attrition from care between HIV testing and antiretroviral therapy (ART) initiation have been documented in sub-Saharan Africa, contributing to persistently low CD4 cell counts at treatment initiation. One reason for this is that starting ART in many countries is a lengthy and burdensome process, imposing long waits and multiple clinic visits on patients. We estimated the effect on uptake of ART and viral suppression of an accelerated initiation algorithm that allowed treatment-eligible patients to be dispensed their first supply of antiretroviral medications on the day of their first HIV-related clinic visit. Methods and Findings RapIT (Rapid Initiation of Treatment) was an unblinded randomized controlled trial of single-visit ART initiation in two public sector clinics in South Africa, a primary health clinic (PHC) and a hospital-based HIV clinic. Adult (≥18 y old), non-pregnant patients receiving a positive HIV test or first treatment-eligible CD4 count were randomized to standard or rapid initiation. Patients in the rapid-initiation arm of the study (“rapid arm”) received a point-of-care (POC) CD4 count if needed; those who were ART-eligible received a POC tuberculosis (TB) test if symptomatic, POC blood tests, physical exam, education, counseling, and antiretroviral (ARV) dispensing. Patients in the standard-initiation arm of the study (“standard arm”) followed standard clinic procedures (three to five additional clinic visits over 2–4 wk prior to ARV dispensing). Follow up was by record review only. The primary outcome was viral suppression, defined as initiated, retained in care, and suppressed (≤400 copies/ml) within 10 mo of study enrollment. Secondary outcomes included initiation of ART ≤90 d of study enrollment, retention in care, time to ART initiation, patient-level predictors of primary outcomes, prevalence of TB symptoms, and the feasibility and acceptability of the intervention.

    Approximately 1.1 million, or 13 %, of all TB cases in 2013 were coinfected with HIV, and in some African countries, such as Botswana and Swaziland, 60-80 % of TB cases are coinfected with HIV. Effective therapies for both HIV and TB exist, yet patients presenting with TB and advanced HIV still experience high rates of morbidity and mortality despite initiation of both antitubercular and antiretroviral therapy (ART). Previous reviews and research have focused largely on TB-associated immune reconstitution inflammatory syndrome (TB-IRIS) as a type of complicated outcome on ART in advanced HIV/TB, but recent data indicate that immunologic failure despite suppressive ART is associated with early mortality. In this review, we examine recent findings regarding early mortality in HIV/TB and emerging concepts in the pathophysiology of TB-IRIS, in order to provide an integrated view of factors determining outcomes in coinfected people as well as highlight key needs for future research and therapeutic development.

    ABSTRACT Understanding the origin of HIV variants during viral rebound may provide insight into the composition of the HIV reservoir and has implications for the design of curative interventions. HIV single-genome sequences were obtained from 10 AIDS Clinical Trials Group participants who underwent analytic antiretroviral therapy (ART) interruption (ATI). Rebounding variants were compared with those in pre-ART plasma in all 10 participants and with on-ART peripheral blood mononuclear cell (PBMC)-associated DNA and RNA (CA-RNA) in 7/10 participants. The highest viral diversities were found in the DNA and CA-RNA populations. In 3 of 7 participants, we detected multiple, identical DNA and CA-RNA sequences during suppression on ART that exactly matched plasma HIV sequences. Hypermutated DNA and CA-RNA were detected in four participants, contributing to diversities in these compartments that were higher than in the pre-ART and post-ATI plasma. Shifts in the viral rebound populations could be detected in some participants over the 2- to 3-month observation period. These findings suggest that a source of initial rebound viremia could be populations of infected cells that clonally expanded prior to and/or during ART, some of which were already expressing HIV RNA before treatment was interrupted. These clonally expanding populations of HIV-infected cells may represent an important target for strategies aimed at achieving reservoir reduction and sustained virologic remission. IMPORTANCE Antiretroviral therapy alone cannot eradicate the HIV reservoir, and viral rebound is generally rapid after treatment interruption. It has been suggested that clonal expansion of HIV-infected cells is an important mechanism of HIV reservoir persistence, but the contribution of these clonally proliferating cells to the rebounding virus is unknown. We report a study of AIDS Clinical Trials Group participants who underwent treatment interruption and compared rebounding plasma virus with that

    Persistent reservoirs remain the major obstacles to achieve an HIV-1 cure. Prolonged early antiretroviral therapy (ART) may reduce the extent of reservoirs and allow for virological control after ART discontinuation. We compared HIV-1 reservoirs in a cross-sectional study using polymerase chain reaction-based techniques in blood and tissue of early-treated seroconverters, late-treated patients, ART-naïve seroconverters, and long-term non-progressors (LTNPs) who have spontaneous virological control without treatment. A decade of early ART reduced the total and integrated HIV-1 DNA levels compared with later treatment initiation, but not reaching the low levels found in LTNPs. Total HIV-1 DNA in rectal biopsies did not differ between cohorts. Importantly, lower viral transcription (HIV-1 unspliced RNA) and enhanced immune preservation (CD4/CD8), reminiscent of LTNPs, were found in early compared to late-treated patients. This suggests that early treatment is associated with some immunovirological features of LTNPs that may improve the outcome of future interventions aimed at a functional cure.

    HIV/AIDS-associated immune reconstitution inflammatory syndrome (IRIS) is defined as a paradoxical worsening or unmasking of infections and autoimmune diseases, following initiation of combination anti-retroviral therapy (cART). More recently, the case definition of IRIS has been broadened to include certain malignancies including Kaposi’s sarcoma, and less frequently Hodgkin’s and non-Hodgkin’s lymphoma (NHL). Here in we describe 3 patients infected with HIV who began cART and within a median of 15 weeks each achieved non-detectable HIV viral loads, and yet within 6 months presented for medical attention with fevers, night sweats, weight loss and bulky lymphadenopathy. Laboratory studies included elevated lactate dehydrogenase and β-2 microglobulin levels and well preserved CD4+ lymphocyte counts in excess of 350 cells/µL. In each patient lymph node biopsies were diagnostic of Burkitt lymphoma (BL). Patients were managed with multi-agent chemotherapy in conjunction with cART. We also survey the medical literature of other cases of IRIS-associated BL. Although the pathogenesis of IRIS-associated BL is not well elucidated, chronic antigenic stimulation coupled with immune deterioration, followed by subsequent restoration of the immune response and aberrant cytokine expression may be a pathway to lymphomagenesis. IRIS-associated BL should be suspected in patients with normal or near normal CD4+ lymphocyte counts who develop progressive lymphadenopathy post-initiation of cART. PMID:25458079

    Background As access to antiretroviral therapy (ART) has grown in Africa, attention has turned to evaluating the socio-economic impacts of ART. One key issue is the extent to which improvements in health resulting from ART allows individuals to return to work and earn income. Improvements in health from ART may also be associated with reduced impaired presenteeism, which is the loss of productivity when an ill or disabled individual attends work but accomplishes less at his or her usual tasks or shifts to other, possibly less valuable, tasks. Methods Longitudinal data for this analysis come from company payroll records for 97 HIV-infected tea estate workers (the index group, 56 women, 41 men) and a comparison group of all workers assigned to the same work teams (n = 2485, 1691 men, 794 women) for a 37-month period covering two years before and one year after initiating ART. We used nearest neighbour matching methods to estimate the impacts of HIV/AIDS and ART on three monthly employment outcomes for tea estate workers in Kenya – days plucking tea, days assigned to non-plucking assignments, and kilograms harvested when plucking. Results The female index group worked 30% fewer days plucking tea monthly than the matched female comparison group during the final 9 months pre-ART. They also worked 87% more days on non-plucking assignments. While the monthly gap between the two groups narrowed after beginning ART, the female index group worked 30% fewer days plucking tea and about 100% more days on non-plucking tasks than the comparison group after one year on ART. The male index group was able to maintain a similar pattern of work as their comparison group except during the initial five months on therapy. Conclusion Significant impaired presenteeism continued to exist among the female index group after one year on ART. Future research needs to explore further the socio-economic implications of HIV-infected female workers on ART being less productive than the general

    Research is lacking on factors associated with antiretroviral therapy (ART) sub-optimal adherence among U.S. Latinos, who are disproportionately affected by HIV and face substantial health care barriers. We examined self-reported, patient-initiated changes to ART (i.e., made small/major changes from the antiretroviral drugs prescribed) among HIV-positive Latinos. Trained interviewers administered surveys to 230 participants currently on ART in San Diego, U.S. and Tijuana, Mexico. We identified factors independently associated with ART changes. Participants were Spanish-language dominant (86%), mean age of 41 years, male (77%), and born in Mexico (93%). Patient-initiated changes to ART were reported in 43% of participants. Being female, having ≥1 sexual partner (past 3 months), ≥6 years since HIV diagnosis and poor health were associated with increased odds of ART changes. Findings raise concern about sub-optimal adherence among this binational population. Longitudinal studies are needed to further explore adherence barriers and avenues for intervention. PMID:21800182

    Abstract Reports show that up to 30% of antiretroviral drug-naive patients in Johannesburg have CXCR4-utilizing HIV-1 subtype C. We assessed whether HIV-1 subtype C-infected individuals failing highly active antiretroviral therapy (HAART) have a higher proportion of CXCR4-utilizing viruses compared to antiretroviral drug-naive patients. The V3 loop was sequenced from plasma from 100 randomly selected HAART-failing patients, and tropism was established using predictive algorithms. All patients harbored HIV-1 subtype C with at least one antiretroviral drug resistance mutation. Viral tropism prediction in individuals failing HAART revealed similar proportions (29%) of X4-utilizing viruses compared to antiretroviral drug-naive patients (30%). Findings are in contrast to reports from Durban in which 60% of HAART-failing subjects harbored X4/dual/mixed-tropic viruses. Despite differences in proportions of X4-tropism within South Africa, the high proportion of thymidine analogue mutations (TAMs) and CXCR4-utilizing HIV-1 highlights the need for intensified monitoring of HAART patients and the predicament of diminishing drug options, including CCR5 antagonists, for patients failing therapy.

    Background UNAIDS official estimates of national HIV prevalence are based on trends observed in antenatal clinic surveillance, after adjustment for the reduced fertility of HIV positive women. Uptake of ART may impact on the fertility of HIV positive women, implying a need to re-estimate the adjustment factors used in these calculations. We analyse the effect of antiretroviral therapy (ART) provision on population-level fertility in Southern and East Africa, comparing trends in HIV infected women against the secular trends observed in uninfected women. Methods We used fertility data from four community-based demographic and HIV surveillance sites: Kisesa (Tanzania), Masaka and Rakai (Uganda) and uMkhanyakude (South Africa). All births to women aged 15–44 years old were included in the analysis, classified by mother’s age and HIV status at time of birth, and ART availability in the community. Calendar time period of data availability relative to ART Introduction varied across the sites, from 5 years prior to ART roll-out, to 9 years after. Calendar time was classified according to ART availability, grouped into pre ART, ART introduction (available in at least one health facility serving study site) and ART available (available in all designated health facilities serving study site). We used Poisson regression to calculate age adjusted fertility rate ratios over time by HIV status, and investigated the interaction between ART period and HIV status to ascertain whether trends over time were different for HIV positive and negative women. Results Age-adjusted fertility rates declined significantly over time for HIV negative women in all four studies. However HIV positives either had no change in fertility (Masaka, Rakai) or experienced a significant increase over the same period (Kisesa, uMkhanyakude). HIV positive fertility was significantly lower than negative in both the pre ART period (age adjusted fertility rate ratio (FRR) range 0.51 95%CI 0.42–0.61 to 0

    Background. Combination antiretroviral therapy (cART) generally suppresses the replication of the human immunodeficiency virus type 1 (HIV-1) but does not cure the infection, because proviruses persist in stable latent reservoirs. It has been proposed that low-level proviral reservoirs might predict longer virologic control after discontinuation of treatment. Our objective was to evaluate the impact of very early initiation of cART and temporary treatment interruption on the size of the latent HIV-1 reservoir in vertically infected children. Methods. This retrospective study included 23 perinatally HIV-1-infected children who initiated very early treatment within 12 weeks after birth (n = 14), or early treatment between week 12 and 1 year (n = 9). We measured the proviral reservoir (CD4+ T-cell–associated HIV-1 DNA) in blood samples collected beyond the first year of sustained virologic suppression. Results. There is a strong positive correlation between the time to initiation of cART and the size of the proviral reservoir. Children who initiated cART within the first 12 weeks of life showed a proviral reservoir 6-fold smaller than children initiating cART beyond this time (P < .01). Rapid virologic control after initiation of cART also limits the size of the viral reservoir. However, patients who underwent transient treatment interruptions showed a dramatic increase in the size of the viral reservoir after discontinuation. Conclusions. Initiation of cART during the first 12 weeks of life in perinatally HIV-1-infected children limits the size of the viral reservoir. Treatment interruptions should be undertaken with caution, as they might lead to fast and irreversible replenishment of the viral reservoir. PMID:26063721

    Objective Verbal autopsies (VAs) are interviews with a relative or friend of the deceased; VAs are a technique used in surveillance sites in many countries with incomplete death certification. The goal of this study was to assess the accuracy and validity of data on HIV status and antiretroviral therapy (ART) usage reported in VAs and their influence on physician attribution of cause of death. Design This was a prospective cohort study. Methods The Karonga Health and Demographic Surveillance Site monitors demographic events in a population in a rural area of northern Malawi; a VA is attempted on all deaths reported. VAs are reviewed by clinicians, who, with additional HIV test information collected pre-mortem, assign a cause of death. We linked HIV/ART information reported by respondents during adult VAs to database information on HIV testing and ART use and analysed agreement using chi-square and kappa statistics. We used multivariable logistic regression to analyse factors associated with agreement. Results From 2003 to 2014, out of a total of 1,952 VAs, 80% of respondents reported the HIV status of the deceased. In 2013–2014, this figure was 99%. Of those with an HIV status known to the study, there was 89% agreement on HIV status between the VA and pre-mortem data, higher for HIV-negative people (92%) than HIV-positive people (83%). There was 84% agreement on whether the deceased had started ART, and 72% of ART initiation dates matched within 1 year. Conclusions In this population, HIV/ART information was often disclosed during a VA and matched well with other data sources. Reported HIV/ART status appears to be a reliable source of information to help classification of cause of death. PMID:27293122

    Background Cannabis is increasingly prescribed clinically and utilized by people living with HIV/AIDS (PLWHA) to address symptoms of HIV disease and to manage side effects of antiretroviral therapy (ART). In light of concerns about the possibly deleterious effect of psychoactive drug use on adherence to ART, we sought to determine the relationship between high-intensity cannabis use and adherence to ART among a community-recruited cohort of HIV-positive illicit drug users. Methods We used data from the ACCESS study, an ongoing prospective cohort study of HIV-seropositive illicit drug users linked to comprehensive ART dispensation records in a setting of universal no-cost HIV care. We estimated the relationship between at least daily cannabis use in the last six months, measured longitudinally, and the likelihood of optimal adherence to ART during the same period, using a multivariate linear mixed-effects model accounting for relevant socio-demographic, behavioral, clinical and structural factors. Results From May 2005 to May 2012, 523 HIV-positive illicit drug users were recruited and contributed 2430 interviews. At baseline, 121 (23.1%) participants reported at least daily cannabis use. In bivariate and multivariate analyses we did not observe an association between using cannabis at least daily and optimal adherence to prescribed HAART (Adjusted Odds Ratio = 1.12, 95% Confidence Interval [95% CI]: 0.76 – 1.64, p-value = 0.555.) Conclusions High-intensity cannabis use was not associated with adherence to ART. These findings suggest cannabis may be utilized by PLWHA for medicinal and recreational purposes without compromising effective adherence to ART. PMID:25012624

    Considerable progress has been made in the provision of life-saving antiretroviral therapy (ART) for persons with human immunodeficiency virus (HIV) infection worldwide, resulting in an overall decrease in HIV incidence and acquired immunodeficiency syndrome (AIDS)-related mortality. In the strategic scale-up of HIV care and treatment programs, persons with HIV and tuberculosis (TB) are a priority population for receiving ART. TB is the leading cause of death among persons living with HIV in sub-Saharan Africa and remains a potential risk to the estimated 35 million persons living with HIV globally. Of the 9 million new cases of TB disease globally in 2013, an estimated 1.1 million (13%) were among persons living with HIV; of the 1.5 million deaths attributed to TB in 2013, a total of 360,000 (24%) were among persons living with HIV. ART reduces the incidence of HIV-associated TB disease, and early initiation of ART after the start of TB treatment reduces progression of HIV infection and death among HIV-positive TB patients. To assess the progress in scaling up ART provision among HIV-positive TB patients in 19 countries in sub-Saharan Africa with high TB and HIV burdens, TB and HIV data collected by the World Health Organization (WHO) were reviewed. The results found that the percentage of HIV-positive TB patients receiving ART increased from 37% in 2010 to 69% in 2013. However, many TB cases among persons who are HIV-positive go unreported, and only 38% of the estimated number of HIV-positive new TB patients received ART in 2013. Although progress has been made, the combination of TB and HIV continues to pose a threat to global health, particularly in sub-Saharan Africa. PMID:25426652

    Background Impressive achievements have been made towards achieving universal coverage of antiretroviral therapy (ART) in sub-Saharan Africa. However, the effects of rapid ART scale-up on delays between HIV diagnosis and treatment initiation have not been well described. Methods A retrospective cohort study covering eight years of ART initiators (2004–2011) was conducted at Queen Elizabeth Central Hospital (QECH) in Blantyre, Malawi. The time between most recent positive HIV test and ART initiation was calculated and temporal trends in delay to initiation were described. Factors associated with time to initiation were investigated using multivariate regression analysis. Results From 2004–2011, there were 15,949 ART initiations at QECH (56% female; 8% children [0–10 years] and 5% adolescents [10–20 years]). Male initiators were likely to have more advanced HIV infection at initiation than female initiators (70% vs. 64% in WHO stage 3 or 4). Over the eight years studied, there were declines in treatment delay, with 2011 having the shortest delay at 36.5 days. On multivariate analysis CD4 count <50 cells/μl (adjusted geometric mean ratio [aGMR]: aGMR: 0.53, bias-corrected accelerated [BCA] 95% CI: 0.42-0.68) was associated with shorter ART treatment delay. Women (aGMR: 1.12, BCA 95% CI: 1.03-1.22) and patients diagnosed with HIV at another facility outside QECH (aGMR: 1.61, BCA 95% CI: 1.47-1.77) had significantly longer treatment delay. Conclusions Continued improvements in treatment delays provide evidence that universal access to ART can be achieved using the public health approach adopted by Malawi However, the longer delays for women and patients diagnosed at outlying sites emphasises the need for targeted interventions to support equitable access for these groups.

    Introduction Latinos living with HIV in the Americas share a common ethnic and cultural heritage. In North America, Latinos have a relatively high rate of new HIV infections but lower rates of engagement at all stages of the care continuum, whereas in Latin America antiretroviral therapy (ART) services continue to expand to meet treatment needs. In this analysis, we compare HIV treatment outcomes between Latinos receiving ART in North America versus Latin America. Methods HIV-positive adults initiating ART at Caribbean, Central and South America Network for HIV (CCASAnet) sites were compared to Latino patients (based on country of origin or ethnic identity) starting treatment at North American AIDS Cohort Collaboration on Research and Design (NA-ACCORD) sites in the United States and Canada between 2000 and 2011. Cox proportional hazards models compared mortality, treatment interruption, antiretroviral regimen change, virologic failure and loss to follow-up between cohorts. Results The study included 8400 CCASAnet and 2786 NA-ACCORD patients initiating ART. CCASAnet patients were younger (median 35 vs. 37 years), more likely to be female (27% vs. 20%) and had lower nadir CD4 count (median 148 vs. 195 cells/µL, p<0.001 for all). In multivariable analyses, CCASAnet patients had a higher risk of mortality after ART initiation (adjusted hazard ratio (AHR) 1.61; 95% confidence interval (CI): 1.32 to 1.96), particularly during the first year, but a lower hazard of treatment interruption (AHR: 0.46; 95% CI: 0.42 to 0.50), change to second-line ART (AHR: 0.56; 95% CI: 0.51 to 0.62) and virologic failure (AHR: 0.52; 95% CI: 0.48 to 0.57). Conclusions HIV-positive Latinos initiating ART in Latin America have greater continuity of treatment but are at higher risk of death than Latinos in North America. Factors underlying these differences, such as HIV testing, linkage and access to care, warrant further investigation. PMID:26996992

    Background In recent years, abnormal lipid deposition (both lipoatrophy and fat redistribution) and its related complications have changed from an anecdotal issue into a major problem for HIV (Human Immunodeficiency Virus) infected patients on HAART (Highly Active Anti-Retroviral Therapy). Lipoatrophy and fat redistribution are potentially stigmatizing complications of HAART and leads to poor adherence among patients. Hence we conducted this study to determine the pattern and to assess various risk factors for maldeposition of lipids in HIV patients. Materials and Methods A cross-sectional case series study was conducted in ART PLUS centre, Bellary over a period of 8 months from January to August 2014 in HIV patients on ART to determine risk factors associated with and epidemiological pattern of fat redistribution or atrophy. Results A total of 50 patients with LD {lipodystrophy} (26 with fat redestribution and 24 with lipoatrophy {LA} were diagnosed in this period. Most of them belonged to younger age and was commonly seen in females (76%). Patients with LA had a significantly lower BMI (18.73 ± 7.4), {the p-value being 0.19} compared to LH group (21.54 ± 7.62). The duration of disease was comparable among both groups (6.96 years in LH and 5.79 years in LA group) {p-value is 0.29}. There was a relatively good immunity among these patients with mean CD4 count was 509.23 in LH and 545.91 in LA group {single CD4 count was taken and the p-value was 0.001}. Most of the patients were in TLN (Tenofovir, Lamivudine, Nevirapine) regimen (58%).The duration that patient was on ART before commencement of study varied from patient to patient, but the mean duration was approximately five years in fat redistribution group and 4.5 years in LA group. There were no derangements in lipid and sugar levels among them. Conclusion This study shows the need to identify and impact of LD with respect to treatment adherence in young patients especially female patients. Early community

    Initiation of combined antiretroviral therapy (cART) is associated with bone loss, which may be more intense with regimens including tenofovir. The underlying mechanisms are not well understood. Cross-sectional data have linked tenofovir with higher parathyroid hormone (PTH) concentrations in patients with vitamin D deficiency. We performed a longitudinal study with a 48-week follow-up to evaluate sequential changes in PTH and 25-hydroxyvitamin D [25(OH)D] levels in patients starting cART with either tenofovir/emtricitabine or abacavir/lamivudine. Fifty-seven patients were included, 31 initiating tenofovir/emtricitabine and 26 initiating abacavir/lamivudine. Median PTH levels turned out to be significantly higher among tenofovir/emtricitabine users at week 4 (p=0.01), week 24 (p=0.008), and week 36 (p=0.02), and were above the upper limits of normal values (ULN) at weeks 24, 36, and 48 only in patients receiving tenofovir/emtricitabine. 25(OH)D, serum and urine calcium and phosphate, and renal-tubular maximum reabsorption of phosphate to the glomerular filtration rate (TmP/GFR) levels did not differ between the two treatment arms over the study period. Among tenofovir/emtricitabine users, median (interquartile range) PTH concentrations were significantly higher in patients with suboptimal 25(OH)D levels (<30 μg/liter) at week 24 [63 (57.8-82.4) ng/liter vs. 54.3 (34.4-63.067.5) ng/liter, p=0.05] and week 48 [67.5 (59.6-86.0) ng/liter vs. 41.9 (37.3-68.8) ng/liter, p=0.03]. A multivariable logistic regression model showed that tenofovir/emtricitabine use was an independent predictor of high PTH levels (≥53 ng/liter). Starting cART with tenofovir regimens is associated with an elevation in PTH plasma concentrations soon after introducing the drug. Suboptimal baseline 25(OH)D levels increase the risk of developing secondary hyperparathyroidism among tenofovir users. PMID:21639815

    Background Antiretroviral therapy (ART) initiation for HIV-1 infection is associated with 2-6% loss in bone mineral density (BMD). Objective To evaluate vitamin D3 (4000 IU daily) plus calcium (1000 mg calcium carbonate daily) supplementation on bone loss associated with ART initiation. Design 48-week prospective, randomized, double-blind, placebo-controlled study. Setting Thirty nine AIDS Clinical Trials Network research units. Participants ART-naïve HIV-infected adults. Measurements BMD by dual-energy X-ray absorptiometry (DXA); 25-hydroxy vitamin D (25(OH)D) levels, parathyroid hormone (PTH), phosphate metabolism, markers of bone turnover and systemic inflammation. Results 165 eligible subjects were randomized (79 Vitamin D/calcium (VitD/Cal); 86 placebo); 142 subjects with evaluable DXA data were included in the primary analysis. The study arms were well-balanced at baseline: median age 33 years; 90% male; 33% non-Hispanic black; median CD4 count 341 cells/mm3; and median 25(OH)D 23 ng/mL (57 nmol/L). At 48 weeks, subjects receiving placebo had greater decline in total hip BMD than VitD/Cal: −3.19% median change (1st-3rd quartile (Q1, Q3) −5.12%, −1.02%) vs. (−1.46% −3.16%,−0.40%). respectively (p=0.001). Lumbar spine BMD loss for the two groups was similar: −2.91% (−4.84%, −1.06%) vs. −1.41% (−3.78%, 0.00%), (p=0.085). At week 48, 90% of participants achieved HIV-1 RNA <50 copies/mL. Levels of 25(OH)D3 increased in the VitD/Cal but not the placebo group: median change of 24.5 (14.6, 37.8) vs. 0.7 (−5.3, 4.3) ng/mL, respectively (p<0.001). Additionally, increases in markers of bone turnover were blunted in the VitD/Cal group. Limitations No international sites were included; only 48 weeks of follow up Conclusion Vitamin D/calcium supplementation mitigates the loss of BMD seen with initiation of efavirenz/emtricitabine/tenofovir, particularly at the total hip, which is the site of greatest concern for fragility fracture.

    Hepatitis C virus (HCV) co-infection and biological sex may each affect response to antiretroviral therapy (ART), yet no studies have examined HIV-associated outcomes by both HCV status and sex. We conducted a cohort study of HIV-infected adults initiating ART in Kaiser Permanente California during 1996-2011. We used piecewise linear regression to assess CD4 changes by sex and HCV status over 5 years. We used Cox regression to estimate hazard ratios (HR) by sex and HCV status for HIV RNA <500 copies/mL over 1 year, and for AIDS and death over the follow-up period. Among 12,865 subjects, there were 154 HIV/HCV-co-infected women, 1000 HIV/HCV-co-infected men, 1088 HIV-mono-infected women, and 10,623 HIV-mono-infected men. CD4 increases were slower in the first year for HIV/HCV-co-infected women (75 cells/μL) and men (70 cells/μL) compared with HIV-mono-infected women (145 cells/μL) and men (120 cells/μL; p<0.001). After 5 years, women had higher CD4 than men in both HIV-mono-infected (598 vs. 562 cells/μL, p=0.003) and HIV/HCV-co-infected individuals (567 vs. 509 cells/μL, p=0.003). Regardless of sex, HIV/HCV co-infection was associated with 40% higher mortality [95% confidence interval (CI): 1.2-1.6] compared with HIV mono-infection, but was not associated with AIDS (HR 1.1, 95% CI: 0.9-1.3) or achieving HIV RNA <500 copies/mL (HR 1.0, 95% CI: 0.9-1.1). HIV/HCV-co-infected men and women have slower CD4 recovery after starting ART and have increased mortality compared with HIV-mono-infected men and women. HCV should be aggressively treated in HIV/HCV-co-infected adults, regardless of sex. PMID:26061798

    Aim: This study evaluated the suspected adverse drug reactions (ADR) reported from a spontaneous reporting program in Human Immunodeficiency Virus (HIV) positive patients receiving antiretroviral therapy (ART) in Nigeria Materials and Methods: This descriptive study analyzed individual case safety reports (ICSRs) in HIV-positive patients receiving ART between January 2011 and December 2011 in 38 secondary hospitals. All ICSRs during this period were included. Chi-square was used to test the association between variables at 95% confidence interval. Results: From 1237 ICSRs collated, only 1119 (90.5%) were valid for analysis. Mean age of patients was 35.3 (95%CI, 35.1–35.5) years; and 67.1% were females. A total of 1679 ADR cases were reported, a mean (± Standard Deviation, SD) of 1.5 (± 0.8) ADR cases per patient. Of reported ADRs, 63.2%, 8.2% and 19.3% occurred in patients on Zidovudine-based, Stavudine-based and Tenofovir-based regimens, respectively. The commonest ADRs included (12.0%) peripheral neuropathy, (11.4%) skin rash, (10.1%) pruritus and (6.5%) dizziness. ADR occurrence was associated with ART regimens, concomitant medicines and age (P < 0.05) unlike gender. Anaemia was associated with Zidovudine (AZT)/ Lamivudine (3TC) /Nevirapine (NEV) regimen [Odds ratio, OR = 6.4 (3.0–13.8); P < 0.0001], and peripheral neuropathy with Stavudine (d4T)/3TC/NEV regimen [OR = 8.7 (5.8–30.0), P < 0.0001] and Tenofovir (TDF)/Emtricitabine (FTC)/Efavirenz (EFV) regimen [OR = 2.1 (1.0–4.1), P = 0.0446]. Skin rash and peripheral neuropathy were associated with patients aged < 15years [OR = 3.0 (1.3–6.6), P = 0.0056] and 45–59years [OR = 1.9 (1.3–2.7), P = 0.0006] respectively. Palpitation and polyuria were associated with Salbutamol [OR = 55.7 (4.9–349.6), P = 0.0000] and Nonsteroidal anti-inflammatory drugs (NSAIDS) [OR = 50.2 (0.9–562.1), P = 0.0040] respectively. Conclusion: ADRs were less likely to occur in patients on stavudine-based and tenofovir

    Background Patients’ experiences are a reflection of what has happened during the care process and, therefore, provide information about the performance of health care professional workers. They refer to the process of care provision at the antiretroviral therapy (ART) sites. Aim and setting This article explored the perceptions of HIV-positive patients of care received at the Gateway Clinic of the regional hospital that provides antiretroviral treatment in the Vhembe district. Methods A qualitative, explorative and descriptive design was used. A non-probability, convenient sampling method was used to select 20 HIV-positive patients who were above 18 years of age. In-depth individual interviews were used to collect data. Data were analysed through Tech’s open coding method. Results One theme and two sub-themes emerged, namely positive experiences related to the environment and attitudes of health professionals, and negative experiences concerning the practices by health care providers. Conclusion Patients’ perceptions of quality of, and satisfaction with, health care may affect health outcomes. Recommendations are made to consider, practice and strengthen the protocols, the standard operating procedures and the principles of infection control in the health facilities. PMID:27380841

    Cryptococcal meningitis is one of the most lethal fungal infections in patients with acquired immune deficiency syndrome (AIDS). The incidence of and mortality from cryptococcal meningitis have markedly decreased since the introduction of combination antiretroviral therapy (cART). However, despite its benefits, the initiation of cART results in immune reconstitution inflammatory syndrome (IRIS) in some patients. Although IRIS is occasionally difficult to distinguish from relapse or treatment failure, the distinction is important because IRIS requires a different treatment. Here, we present the case of a patient with AIDS who developed symptoms of cryptococcal IRIS 41 months after starting cART. To the best of our knowledge, the time between cART initiation and the onset of cryptococcal IRIS in this patient is the longest that has been reported in the literature. PMID:26425133

    Migrant populations face increased HIV vulnerabilities, including limited access to antiretroviral therapy. Civil conflict in Myanmar has displaced thousands of people from the minority Shan ethnic group into northern Thailand, where they bear a disproportionate HIV burden. To identify barriers and facilitators of antiretroviral therapy use in this population, we conducted a rapid ethnographic assessment and case study with a clinical sample of Shan migrants receiving treatment for HIV in a district hospital in Chiang Mai, Thailand, Thai nurses providing their care, and health care administrators (n = 23). Barriers included fears of arrest and deportation, communication difficulties, perceived social marginalization, limited HIV knowledge, and lack of finances. Facilitating factors included hospital-based migrant registration services and community outreach efforts involving support group mobilization, referral practices, and radio broadcasts. These findings provided a contextualized account to inform policies, community interventions, and nursing practice to increase treatment access for minority migrant groups. PMID:27188762

    2015-01-01

    The human immunodeficiency virus (HIV) spreads more efficiently in vitro when infected cells directly contact uninfected cells to form virological synapses. A hallmark of virological synapses is that viruses can be transmitted at a higher multiplicity of infection (MOI) that, in vitro, results in a higher number of proviruses. Whether HIV also spreads by cell-cell contact in vivo is a matter of debate. Here we discuss recent data that suggest that contact-mediated transmission largely manifests itself in vivo as CD4+ T cell depletion. The assault of a cell by a large number of incoming particles is likely efficiently sensed by the innate cellular surveillance to trigger cell death. The large number of particles transferred across virological synapses has also been implicated in reduced efficacy of antiretroviral therapies. Thus, antiretroviral therapies must remain effective against the high MOI observed during cell-to-cell transmission to inhibit both viral replication and the pathogenesis associated with HIV infection.

    Objective To assess the effects of decreased antiretroviral therapy exposure on body fat and metabolic parameters. Design Sub-study of the SMART study in which participants were randomized to intermittent CD4-guided (DC group) or to continuous (VS group) antiretroviral therapy. Methods Participants at 33 sites were co-enrolled in the SMART Body Composition Sub-study. Regional fat was assessed annually by whole-body dual-energy X-ray absorptiometry and abdominal computed tomography. Fasting metabolic parameters were assessed at months 4, 8, and annually. Treatment groups were compared for changes in fat and metabolic markers using longitudinal mixed models. Results Two hundred seventy-five patients were randomized to the DC (n=142) or VS (n=133) groups, and followed for a median of 2.0 years. By month 12, limb fat (DC-VS difference 9.8%, 95% confidence interval [CI] 3.5 to 16.1; P=0.003) and subcutaneous abdominal fat (DC-VS difference 14.3 cm2, 95% CI −0.1 to 28.7; P=0.05) increased in the DC group. There was no treatment difference on visceral abdominal fat (DC-VS difference −2.1%, 95% CI −13.5 to 9.4; P=0.72). Lipids significantly decreased in the DC group by month 4 and treatment differences persisted throughout follow-up (P≤0.001). By 12 months, hemoglobin A1C increased in the DC (+0.3%) and remained stable in the VS group (P=0.003); the treatment difference remained significant through follow-up (P=0.02). Conclusions After 12 months, intermittent antiretroviral therapy increased subcutaneous fat, had no effect on visceral abdominal fat, decreased plasma lipids, and increased hemoglobin A1C compared with continuous antiretroviral therapy.

    Background Cystatin C has been proposed as an alternative marker of renal function. We sought to determine if participants randomized to episodic use of antiretroviral therapy guided by CD4+ count (drug conservation; DC) had altered cystatin C levels compared to those randomised to continuous antiretroviral therapy (viral suppression; VS) in the Strategies for Management of Antiretroviral Therapy Trial, and to identify factors associated with increased cystatin C. Methods Cystatin C was measured in plasma collected at randomization, 1, 2, 4, 8 and 12 months after randomization in a random sample of 249 and 250 participants in the DC and VS groups respectively. Logistic regression was used to model the odds of ≥ 0.15 mg/dl increase in cystatin C (1 standard deviation [SD]) in the first month after randomisation, adjusting for demographic and clinical characteristics. Results At randomisation, mean (SD) cystatin C level was 0.99 (0.26 mg/dl) and 1.01 (0.28 mg/dl) in the DC and VS arms respectively (p=0.29). In the first month after randomisation, 21.8% and 10.6% had ≥0.15 mg/dl increase in cystatin C in the DC and VS arm respectively (p=0.0008). The difference in cystatin C between the treatment arms was maintained through 1 year after randomisation. After adjustment, participants in the VS arm had significantly reduced odds of ≥0.15 mg/dl increase in cystatin C in the first month (OR 0.42; 95% CI 0.23–0.74, p=0.0023). Conclusions These results demonstrate that interruption of antiretroviral therapy is associated with an increase in cystatin C, which may reflect worsened renal function. PMID:19050388

    Rationale: Experimental and epidemiological evidence suggests that neutrophils are important in the host response to tuberculosis. HIV infection, which increases the risk of tuberculosis, adversely affects neutrophil function. Objectives: To determine the impact of HIV and antiretroviral therapy on neutrophil antimycobacterial activity. Methods: We performed a cross-sectional comparison of neutrophil functions in 20 antiretroviral-naive HIV-infected and 20 HIV-uninfected individuals using luminescence-, flow cytometry–, and ELISA-based assays. We then conducted a prospective study in the HIV-infected individuals investigating these parameters during the first 6 months of antiretroviral therapy. Surface markers of neutrophil activation were investigated in a separate cohort using flow cytometry. Measurements and Main Results: HIV infection impaired control of Mycobacterium tuberculosis by neutrophils (mean ratio of mycobacterial luminescence in neutrophil samples vs. serum controls at 1 hour in HIV-infected participants, 0.88 ± 0.13 vs. HIV-uninfected participants, 0.76 ± 0.14; P = 0.01; at 24 hours, 0.82 ± 0.13 vs. 0.71 ± 0.13; P = 0.01). The extent of impairment correlated with log[HIV viral load]. Neutrophil cell death after 24 hours’ incubation with M. tuberculosis was higher in the HIV-infected cohort (85.3 ± 11.8% vs. 57.9 ± 22.4% necrotic cells; P < 0.0001). Neutrophils from HIV-infected participants demonstrated significantly more CD62L-negative cells (median, 23.0 vs. 8.5%; P = 0.008) and CD16-negative cells (3.2 vs. 1.3%, P = 0.03). Antiretroviral therapy restored mycobacterial restriction and pattern of neutrophil death toward levels seen in HIV-uninfected persons. Conclusions: Neutrophils in antiretroviral-naive HIV-infected persons are hyperactivated, eliminate M. tuberculosis less effectively than in HIV-uninfected individuals, and progress rapidly to necrotic cell death. These factors are

    In sub-Saharan Africa models of care need to adapt to support continued scale up of antiretroviral therapy (ART) and retain millions in care. Task shifting, coupled with community participation has the potential to address the workforce gap, decongest health services, improve ART coverage, and to sustain retention of patients on ART over the long-term. The evidence supporting different models of community participation for ART care, or community-based
