    Full Text Available BACKGROUND: Patients starting antiretroviral therapy (ART for acquired immunodeficiency syndrome (AIDS in sub-Saharan Africa have high rates of mortality in the initial weeks of treatment. We assessed the association of serum phosphate with early mortality among HIV-infected adults with severe malnutrition and/or advanced immunosuppression. METHODOLOGY/PRINCIPAL FINDINGS: An observational cohort of 142 HIV-infected adults initiating ART in Lusaka, Zambia with body mass index (BMI <16 kg/m(2 or CD4(+ lymphocyte count <50 cells/microL, or both, was followed prospectively during the first 12 weeks of ART. Detailed health and dietary intake history, review of systems, physical examination, serum metabolic panel including phosphate, and serum ferritin and high-sensitivity C-reactive protein (hsCRP were monitored. The primary outcome was mortality. Baseline serum phosphate was a significant predictor of mortality; participants alive at 12 weeks had a median value of 1.30 mmol/L (interquartile range [IQR]: 1.04, 1.43, compared to 1.06 mmol/L (IQR: 0.89, 1.27 among those who died (p<0.01. Each 0.1 mmol/L increase in baseline phosphate was associated with an incremental decrease in mortality (AHR 0.83; 95% CI 0.72 to 0.95. The association was independent of other metabolic parameters and known risk factors for early ART-associated mortality in sub-Saharan Africa. While participant attrition represented a limitation, it was consistent with local program experience. CONCLUSIONS/SIGNIFICANCE: Low serum phosphate at ART initiation was an independent predictor of early mortality among HIV patients starting ART with severe malnutrition or advanced immunosuppression. This may represent a physiologic phenomenon similar to refeeding syndrome, and may lead to therapeutic interventions that could reduce mortality.

    Full Text Available Abstract Background The scarcity of physicians in sub-Saharan Africa – particularly in rural clinics staffed only by non-physician health workers – is constraining access to HIV treatment, as only they are legally allowed to start antiretroviral therapy in the HIV-positive patient. Here we present a pilot study from Uganda assessing agreement between non-physician clinicians (nurses and clinical officers and physicians in their decisions as to whether to start therapy. Methods We conducted the study at 12 government antiretroviral therapy sites in three regions of Uganda, all of which had staff trained in delivery of antiretroviral therapy using the WHO Integrated Management of Adult and Adolescent Illness guidelines for chronic HIV care. We collected seven key variables to measure patient assessment and the decision as to whether to start antiretroviral therapy, the primary variable of interest being the Final Antiretroviral Therapy Recommendation. Patients saw either a clinical officer or nurse first, and then were screened identically by a blinded physician during the same clinic visit. We measured inter-rater agreement between the decisions of the non-physician health workers and physicians in the antiretroviral therapy assessment variables using simple and weighted Kappa analysis. Results Two hundred fifty-four patients were seen by a nurse and physician, while 267 were seen by a clinical officer and physician. The majority (> 50% in each arm of the study were in World Health Organization Clinical Stages I and II and therefore not currently eligible for antiretroviral therapy according to national antiretroviral therapy guidelines. Nurses and clinical officers both showed moderate to almost perfect agreement with physicians in their Final Antiretroviral Therapy Recommendation (unweighted κ = 0.59 and κ = 0.91, respectively. Agreement was also substantial for nurses versus physicians for assigning World Health Organization Clinical

    2015-04-01

    Full Text Available The most recent version of the Southern African HIV Clinicians Society’s adult antiretroviral therapy (ART guidelines was published in December 2014. In the 27 August 2015 edition of the New England Journal of Medicine, two seminal randomised controlled trials that addressed the optimal timing of ART in HIV-infected patients with high CD4 counts were published: Strategic timing of antiretroviral therapy (START and TEMPRANO ANRS 12136 (Early antiretroviral treatment and/or early isoniazid prophylaxis against tuberculosis in HIV-infected adults. The findings of these two trials were consistent: there was significant individual clinical benefit from starting ART immediately in patients with CD4 counts higher than 500 cells/μL rather than deferring until a certain lower CD4 threshold or clinical indication was met. The findings add to prior evidence showing that ART reduces the risk of onward HIV transmission. Therefore, early ART initiation has the public health benefits of potentially reducing both HIV incidence and morbidity. Given this new and important evidence, the Society took the decision to provide a specific update on the section of the adult ART guidelines relating to when ART should be initiated.

    Full Text Available These guidelines are intended as an update to those published in the Southern African Journal of HIV Medicine in January 2008. Since the release of the previous guidelines, the scale-up of antiretroviral therapy (ART in Southern Africa has continued to grow. Cohort studies from the region show excellent clinical outcomes; however, ART is still being started late (in advanced disease, resulting in relatively high early mortality rates. New data on antiretroviral (ARV tolerability in the region and several new ARV drugs have become available. Although currently few in number, some patients in the region are failing protease inhibitor (PI-based second-line regimens. To address this, guidelines on third-line (or ‘salvage’ therapy have been expanded.

    2012-01-01

    Full Text Available 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.

    Background. In Western Europe, North America, and Australia, large cohort collaborations have been able to estimate the short-term CD4 cell count–specific risk of AIDS or death in untreated human immunodeficiency virus (HIV)–infected adults with high CD4 cell counts. In sub–Saharan Africa, these CD4 cell count–specific estimates are scarce. Methods. From 1996 through 2006, we followed up 2 research cohorts of HIV-infected adults in Côte d’Ivoire. This included follow-up off antiretroviral therapy (ART) across the entire spectrum of CD4 cell counts before the ART era, and only in patients with CD4 cell counts >200 cells/μL once ART became available. Data were censored at ART initiation. We modeled the CD4 cell count decrease using an adjusted linear mixed model. CD4 cell count–specific rates of events were obtained by dividing the number of first events occurring in a given CD4 cell count stratum by the time spent in that stratum. Results. Eight hundred sixty patients were followed off ART over 2789 person-years (PY). In the ≥650, 500–649, 350–499, 200–349, 100–199, 50–99, and 0–49 cells/μL CD4 cell count strata, the rates of AIDS or death were 0.9, 1.7, 3.7, 10.4, 30.9, 60.8, and 99.9 events per 100 PY, respectively. In patients with CD4 cell counts ≥200 CD4 cells/μL, the most frequent AIDS-defining disease was tuberculosis (decreasing from 4.0 to 0.6 events per 100 PY for 200–349 and ≥650 cells/μL, respectively), and the most frequent HIV non-AIDS severe diseases were visceral bacterial diseases (decreasing from 9.1 to 3.6 events per 100 PY). Conclusions. Rates of AIDS or death, tuberculosis, and invasive bacterial diseases are substantial in patients with CD4 cell counts ≥200 cells/μL. Tuberculosis and bacterial diseases should be the most important outcomes in future trials of early ART in sub–Saharan Africa. PMID:22173233

    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

    IMPORTANCE New data and therapeutic options warrant updated recommendations for the use of antiretroviral drugs (ARVs) to treat or to prevent HIV infection in adults. OBJECTIVE To provide updated recommendations for the use of antiretroviral therapy in adults (aged ≥18 years) with established HIV infection, including when to start treatment, initial regimens, and changing regimens, along with recommendations for using ARVs for preventing HIV among those at risk, including preexposure and postexposure prophylaxis. EVIDENCE REVIEW A panel of experts in HIV research and patient care convened by the International Antiviral Society-USA reviewed data published in peer-reviewed journals, presented by regulatory agencies, or presented as conference abstracts at peer-reviewed scientific conferences since the 2014 report, for new data or evidence that would change previous recommendations or their ratings. Comprehensive literature searches were conducted in the PubMed and EMBASE databases through April 2016. Recommendations were by consensus, and each recommendation was rated by strength and quality of the evidence. FINDINGS Newer data support the widely accepted recommendation that antiretroviral therapy should be started in all individuals with HIV infection with detectable viremia regardless of CD4 cell count. Recommended optimal initial regimens for most patients are 2 nucleoside reverse transcriptase inhibitors (NRTIs) plus an integrase strand transfer inhibitor (InSTI). Other effective regimens include nonnucleoside reverse transcriptase inhibitors or boosted protease inhibitors with 2 NRTIs. Recommendations for special populations and in the settings of opportunistic infections and concomitant conditions are provided. Reasons for switching therapy include convenience, tolerability, simplification, anticipation of potential new drug interactions, pregnancy or plans for pregnancy, elimination of food restrictions, virologic failure, or drug toxicities.

    Full Text Available BACKGROUND: In adults it is well documented that there are substantial losses to the programme between HIV testing and start of antiretroviral therapy (ART. The magnitude and reasons for loss to follow-up and death between HIV diagnosis and start of ART in children are not well defined. METHODS: We searched the PubMed and EMBASE databases for studies on children followed between HIV diagnosis and start of ART in low-income settings. We examined the proportion of children with a CD4 cell count/percentage after after being diagnosed with HIV infection, the number of treatment-eligible children starting ART and predictors of loss to programme. Data were extracted in duplicate. RESULTS: Eight studies from sub-Saharan Africa and two studies from Asia with a total of 10,741 children were included. Median age ranged from 2.2 to 6.5 years. Between 78.0 and 97.0% of HIV-infected children subsequently had a CD4 cell count/percentage measured, 63.2 to 90.7% of children with an eligibility assessment met the eligibility criteria for the particular setting and time and 39.5 to 99.4% of the eligible children started ART. Three studies reported an association between low CD4 count/percentage and ART initiation while no association was reported for gender. Only two studies reported on pre-ART mortality and found rates of 13 and 6 per 100 person-years. CONCLUSION: Most children who presented for HIV care met eligibility criteria for ART. There is an urgent need for strategies to improve the access to and retention to care of HIV-infected children in resource-limited settings.

The aim of the present study was to assess the cost- effectiveness of treatment with HAART in a large clinical cohort of naïve adults to determine the potential role of single-tablet regimens in the management of patients with human immunodeficiency virus (HIV. An incremental cost-effectiveness ratio analysis was performed, including a quality-adjusted life year approach. Results: In total, 741 patients (females comprising 25.5% were retrospectively included. The mean age was 39 years, the mean CD4 cell count was 266 cells/µL, and the mean viral load was 192,821 copies/mL. The most commonly used backbone was tenofovir + emtricitabine (77.6%; zidovudine + lamivudine was used in 10%, lamivudine + abacavir in 3%, and other nucleoside reverse transcriptase inhibitor (NRTI or NRTI-free regimens in 9.4% of patients. NNRTIs were used in 52.8% of cases, boosted protease inhibitors in 44.1%, and unboosted protease inhibitors and integrase inhibitors in 0.7% and 2.4%, respectively. Starting therapy at CD4 >500 cells/µL and CD4 351–500 cells/µL rather than at <201 cells/µL was the more cost-effective approach. The same consideration was not true comparing current indications with the possibility to start HAART at any CD4 value (eg, >500 cells per µL; in this case, the incremental cost-effectiveness ratio value was €199,130 per quality-adjusted life year gained, a higher value than the one suggested in guidelines.

    Full Text Available Millions of HIV-infected Africans are living longer due to long-term antiretroviral therapy (ART, yet little is known about glucose metabolism disorders in this group. 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.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.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%.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 reconstitution.

    Full Text Available OBJECTIVE: To estimate the prevalence of drug-resistant tuberculosis (TB and describe the resistance patterns in patients commencing antiretroviral therapy (ART in an HIV clinic in Durban, South Africa. DESIGN: Cross-sectional cohort study. METHODS: Consecutive HIV-infected adults (≥ 18y/o initiating HIV care were enrolled from May 2007-May 2008, regardless of signs or symptoms of active TB. Prior TB history and current TB treatment status were self-reported. Subjects expectorated sputum for culture (MGIT liquid and 7H11 solid medium. Positive cultures were tested for susceptibility to first- and second-line anti-tuberculous drugs. The prevalence of drug-resistant TB, stratified by prior TB history and current TB treatment status, was assessed. RESULTS: 1,035 subjects had complete culture results. Median CD4 count was 92/µl (IQR 42-150/µl. 267 subjects (26% reported a prior history of TB and 210 (20% were receiving TB treatment at enrollment; 191 (18% subjects had positive sputum cultures, among whom the estimated prevalence of resistance to any antituberculous drug was 7.4% (95% CI 4.0-12.4. Among those with prior TB, the prevalence of resistance was 15.4% (95% CI 5.9-30.5 compared to 5.2% (95% CI 2.1-8.9 among those with no prior TB. 5.1% (95% CI 2.4-9.5 had rifampin or rifampin plus INH resistance. CONCLUSIONS: The prevalence of TB resistance to at least one drug was 7.4% among adults with positive TB cultures initiating ART in Durban, South Africa, with 5.1% having rifampin or rifampin plus INH resistance. Improved tools for diagnosing TB and drug resistance are urgently needed in areas of high HIV/TB prevalence.

    Full Text Available Introduction: These guidelines are part of the French Experts’ recommendations for the management of people living with HIV/AIDS, which were made public and submitted to the French health authorities in September 2013. The objective was to provide updated recommendations for antiretroviral treatment (ART of HIV-positive adults. Guidelines included the following topics: when to start, what to start, specific situations for the choice of the first session of antiretroviral therapy, optimization of antiretroviral therapy after virologic suppression, and management of virologic failure. Methods: Ten members of the French HIV 2013 expert group were responsible for guidelines on ART. They systematically reviewed the most recent literature. The chairman of the subgroup was responsible for drafting the guidelines, which were subsequently discussed within, and finalized by the whole expert group to obtain a consensus. Recommendations were graded for strength and level of evidence using predefined criteria. Economic considerations were part of the decision-making process for selecting preferred first-line options. Potential conflicts of interest were actively managed throughout the whole process. Results: ART should be initiated in any HIV-positive person, whatever his/her CD4 T-cell count, even when >500/mm3. The level of evidence of the individual benefit of ART in terms of mortality or progression to AIDS increases with decreasing CD4 cell count. Preferred initial regimens include two nucleoside reverse transcriptase inhibitors (tenofovir/emtricitabine or abacavir/lamivudine plus a non-nucleoside reverse transcriptase inhibitor (efavirenz or rilpivirine, or a ritonavir-boosted protease inhibitor (atazanavir or darunavir. Raltegravir, lopinavir/r, and nevirapine are recommended as alternative third agents, with specific indications and restrictions. Specific situations such as HIV infection in women, primary HIV infection, severe immune suppression

    Full Text Available This document serves to guide clinicians and programme managers on how to switch from 3 separate antiretroviral (ARV drugs to the new, single, fixed-dose combination (FDC tablet containing tenofovir (TDF, emtricitabine (FTC and efavirenz (EFV. Summary Transitioning from individual drugs to an FDC tablet needs to be managed carefully, particularly regarding stock management, ordering processes, supply-chain integrity and comprehensive patient counselling. Priority groups • Initially, FDC supply will be insufficient to provide for all FDC-suitable patients • Therefore, the National Department of Health (NDoH has recommended that the following patient groups be prioritized for FDC initiation/switch: • Priority group 1: All HIV-positive patients newly initiating ART – adults, adolescents and pregnant women (regardless of CD4 count (amendment to the guidelines for the prevention of mother-to-child transmission of HIV (PMTCT anticipated in April 2013 – and who do not have contra-indications to the FDC component drugs • Priority group 2: HIV-positive pregnant women and breastfeeding mothers currently stable on lamivudine (3TC, TDF and EFV • Priority group 3: Virologically suppressed patients on a stavudine (d4T-based regimen and who have normal renal function • Priority group 4: Stable patients receiving individual TDF, 3TC and EFV and who have tuberculosis (TB co-infection • Priority group 5: Stable patients receiving individual TDF, 3TC and EFV and who have other co-morbidites (e.g. hypertension, diabetes • Priority group 6: Patients receiving individual TDF, 3TC and EFV and who request to switch to the FDC treatment • Priority group 7: Patients receiving individual TDF, 3TC and EFV and who, after counselling, agree to switch to the FDC treatment. Important: Clinic staff must co-ordinate this process and only switch as many patients to the FDC tablet as stock allows. This should avoid patients being switched back and forth

  8. START or SMART? Timing of Antiretroviral Therapy Initiation and Cardiovascular Risk for People With Human Immunodeficiency Virus Infection.

    2016-01-01

    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

    Full Text Available Commencement of antiretroviral treatment (ART in severely immunosuppressed HIV-infected persons is associated with unmasking of subclinical disease. The subset of patients that are diagnosed with tuberculosis (TB disease while on ART have been classified as ART-associated TB. Few studies have reported the incidence of ART-associated TB and unmasking TB-IRIS according to the International Network for the Study of HIV-Associated IRIS (INSHI consensus definition. To determine the incidence and predictors of ART-associated TB, we screened 219 patients commencing ART at the Infectious Diseases Clinic in Kampala, Uganda for TB by symptoms, sputum microscopy, and chest X-rays and followed them for one year. Fourteen (6.4% patients were diagnosed with TB during followup. Eight (3.8% patients had ART-associated TB (incidence rate of 4.3 per 100 person years; of these, three patients fulfilled INSHI criteria for unmasking TB-associated IRIS (incidence rate of 1.6 per 100 person years. A body mass index of less than 18.5 kg/m2 BMI (HR 5.85 95% CI 1.24–27.46, P=.025 and a C-reactive protein greater than 5 mg/L (HR 8.23 95% CI 1.36–38.33, P=.020 were risk factors for ART-associated TB at multivariate analysis. In conclusion, with systematic TB screening (including culture and chest X-ray, the incidence of ART-associated TB is relatively low in settings with high HIV and TB prevalence.

  12. Immune reconstitution inflammatory syndrome in HIV-infected patients with mycobacterial infections starting highly active anti-retroviral therapy

    International Nuclear Information System (INIS)

    AIM: To describe the radiological appearances of immune reconstitution inflammatory syndrome (IRIS) in human immunodeficiency virus (HIV)-infected patients with mycobacterial infections starting highly active anti-retroviral therapy (HAART). MATERIALS AND METHODS: Five consecutive HIV infected patients with IRIS due to mycobacterial infection were studied. Intercurrent infection and poor drug compliance were excluded as causes of presentation. The chest radiological appearances at the time of starting HAART and at the time of diagnosis of IRIS were compared. RESULTS: In these five patients there was clinical and radiological deterioration, occurring between 10 days and 7 months after starting HAART, leading to unmasking of previously undiagnosed mycobacterial infection or to worsening of mycobacterial disease. All five patients had HAART-induced increases in CD4+ T lymphocyte counts and reductions in peripheral blood HIV 'viral load'. Chest radiographic abnormalities due to IRIS included marked mediastinal lymphadenopathy in three patients--severe enough to produce tracheal compression in two patients (one of whom had stridor)--and was associated with new pulmonary infiltrates in two patients. The other two patients had new infiltrates, which in one patient was associated with a pleural effusion. CONCLUSION: These cases illustrate the diverse chest radiographic appearances of IRIS occurring after HAART in patients with mycobacterial and HIV co-infection. Marked mediastinal lymphadenopathy occurred in three of these five patients (with associated tracheal narrowing in two patients); four patients developed pulmonary infiltrates and one had an effusion. The cases further highlight that the onset of IRIS may be delayed for several months after HAART is started

    High mortality rates have been reported in the first 90 days of antiretroviral therapy in Zambia and other low-income countries. We report a case of acute hypophosphataemia and hypokalaemia in the first week of antiretroviral therapy in a patient with extreme AIDS wasting. Given its occurrence in an extremely wasted patient, it may be physiologically similar to refeeding syndrome but other causes could be relevant as well. Acute hypophosphataemia may contribute to early antiretroviral therapy associated mortality in low-income countries.

    2011-12-01

    We investigated whether polymorphisms in human candidate genes could be associated with a different risk of developing lipodystrophy and dyslipidemia in HIV-infected patients starting combination antiretroviral therapy (cART). Genomic DNA samples from white HIV-1-infected patients were analyzed for seven polymorphisms located in the MDR1, TNF-α, APM1, APOE, and LPL genes. Lipid data were retrospectively collected beginning with the initiation of cART. Lipodystrophy was assessed cross-sectionally and then prospectively. The association with lipodystrophy and National Cholesterol Evaluation Program Adult Treatment Panel III-defined lipid thresholds was analyzed using survival analysis and logistic regression. One-hundred and seventy-four patients were genotyped. In 151 patients assessed for lipodystrophy, MDR1 3435 T homozygosis was associated with a higher hazard (adjusted hazard ratio, aHR, versus CT 0.25; p=0.02) and tumor necrosis factor (TNF)-α 308 G homozygosis with a lower hazard (vs. AA aHR 2.14; p=0.04) of developing trunk fat accumulation after adjusting for gender and initial cART type. The TNF 238 GG genotype was associated with a higher risk of developing low HDL-cholesterol levels (adjusted odd ratio, aOR, 5.91; p=0.01) while patients carrying the LPL S477X mutation were at lower risk of reaching high non-HDL-cholesterol levels (aOR 0.39; p=0.05). The APOEe3/3 genotype patients were at lower risk (aOR 0.26, p=0.015), whereas the adiponectin 276 GT carriers were at higher risk of developing hypertriglyceremia (vs. GG aOR 3.10; p=0.04). Knowledge of the effect of genetic determinants on dyslipidemia and lipodystrophy may prompt the investigation of potential pathogenetic mechanisms and might eventually be used for guiding individualized treatment decisions.

    Full Text Available BACKGROUND: In Mozambique during 2004-2007 numbers of adult patients (≥15 years old enrolled on antiretroviral therapy (ART increased about 16-fold, from 60 kg, WHO stage IV (AHR 1.7; 95% CI, 1.3-2.4, reference group WHO stage I/II, lack of co-trimoxazole prescription (AHR 1.4; 95% CI, 1.0-1.8, and later calendar year of ART initiation (AHR 1.5; 95% CI, 1.2-1.8. Rates of immunologic treatment failure and regimen-switch were 14.0 and 0.6 events per 100-patient years, respectively. CONCLUSIONS: ART initiation at earlier disease stages and scale-up of co-trimoxazole among ART patients could improve outcomes. Research to determine reasons for low regimen-switch rates and increasing rates of attrition during program expansion is needed.

    Full Text Available Background: The prevalence of thrombocytopenia among Chinese antiretroviral therapy (ART-naïve HIV-infected adults has not been well-described. The aim of this study was to investigate the prevalence and associated risk factors of thrombocytopenia among Chinese ART-naïve HIV-infected adults. Methods: We performed a cross-sectional study of Chinese adult ART-naïve HIV-infected patients from September 2005 through August 2014. Socio-demographic variables and laboratory results including platelets, CD4+ cell count, and viral load were obtained from medical records. Factors and outcomes associated with thrombocytopenia were assessed using logistic regression. Results: A total of 1730 adult ART-naïve HIV-infected patients was included. The mean age was 38 years. The prevalence of thrombocytopenia was 4.5%. There were significant differences in the prevalence of thrombocytopenia between patients 350 cells/mm 3 (2.8% compared with patients with CD4+ counts of 50-199 cells/mm 3 (7.1% (P = 0.002 and P = 0.005, respectively. The prevalence of thrombocytopenia was significantly different by hepatitis C virus antibody (HCV-Ab seropositivity (10.2% for HCV-Ab positive vs. 3.9% for HCV-Ab negative, P = 0.001. We observed differences in prevalence of thrombocytopenia by mode of transmission of HIV infection: Blood transmission (10.7% versus men who have sex with men (3.9% (P = 0.002 and versus heterosexual transmission (3.9% (P = 0.001. In binary logistic regression analyses, age ≥50 years, HCV-Ab positivity and having a CD4+ cell count of 50-199 cells/mm 3 were significantly associated with thrombocytopenia with adjusted odds ratio of 2.482 (95% confidence interval [CI]: 1.167, 5.281, P = 0.018, 2.091 (95% CI: 1.078, 4.055, P = 0.029 and 2.259 (95% CI: 1.028, 4.962, P = 0.042, respectively.

    Full Text Available BACKGROUND: There are approximately 3 million people aged 50 and older in sub-Saharan Africa who are HIV-positive. Despite this, little is known about the characteristics of older adults who are on treatment and their treatment outcomes. METHODS: A retrospective cohort analysis was performed using routinely collected data with Malawi Ministry of Health monitoring tools from facilities providing antiretroviral therapy services in Zomba district. Patients aged 25 years and older initiated on treatment from July 2005 to June 2010 were included. Differences in survival, by age group, were determined using Kaplan-Meier survival plots and Cox proportional hazards regression models. RESULTS: There were 10,888 patients aged 25 and older. Patients aged 50 and older (N = 1419 were more likely to be male (P<0.0001 and located in rural areas (P = 0.003 than those aged 25-49. Crude survival estimates among those aged 50-59 were not statistically different from those aged 25-49 (P = 0.925. However, survival among those aged 60 and older (N = 345 was worse (P = 0.019 than among those 25-59. In the proportional hazards model, after controlling for sex and stage at initiation, survival in those aged 50-59 did not differ significantly from those aged 25-49 (hazard ratio 1.00 (95% CI: 0.79 to 1.27; P = 0.998 but the hazard ratio was 1.46 (95% CI: 1.03 to 2.06; P = 0.032 for those aged 60 and older compared to those aged 25-49. CONCLUSIONS: Treatment outcomes of those aged 50-59 are similar to those aged 25-49. A better understanding of how older adults present for and respond to treatment is critical to improving HIV services.

  8. Estimated use of abacavir among adults and children enrolled in public sector antiretroviral therapy programmes in Gauteng, South Africa

    2012-09-01

    Full Text Available In South Africa, abacavir (ABC is currently recommended as part of first- and second-line antiretroviral therapy (ART for HIV-positive paediatric patients. Concerns about overprescribing of the drug, particularly to adults, led to an analysis of ABC use in public sector ART programmes. We investigated current prescription of the drug to adults and children accessing ART in 4 public sector programmes across Gauteng Province, South Africa. ABC was almost exclusively prescribed to children initiating ART and adults requiring regimen changes due to drug toxicities. Patterns of ABC use among HIV-positive paediatric patients followed national ART treatment guidelines on the application of the drug. Although ABC is commonly used in the private sector for adults, the current national ART treatment guidelines for adults and adolescents should include ABC as an alternative to standard first- or second-line ART.

    Full Text Available Purpose of the study: To identify the proportion of patients starting ARV treatment with NNRTIs or with a PI/r and to explore and compare their clinical profile establishing different factors whereby physicians select the initial ARV treatment in a Spanish clinical setting. Methods: An observational study was conducted in two different phases. In Phase I a cross-sectional registration was conducted for patients who initiated ARV treatment in a 6-month period in 65 Spanish hospitals. In Phase II clinical and social-demographic features were collected retrospectively of patients who visited HIV clinics between August and November 2010 who had started ARV treatment containing an NNRTIs or a PI/r in Phase I. Summary of results: In Phase I, 1,687 subjects who initiated ARV treatment were registered, of which 53% started with an NNRTI-based regimen whereas 42% started with a PI/r-based regimen. Two percent of the treatment initiations occurred in a clinical trial. In Phase II, 642 patients were paired consecutively and retrospectively. The group of patients was composed of predominantly male subjects (81% vs 19%. The median time between diagnosis and the start of ARV treatment was 3.6±5.3 years. At the initiation of treatment, 72% of patients had a CD4 count below 350 cells/µl. Although treatment based on NNRTIs in naïve patients is the most frequent option in Spain, the analysis of clinical profiles shows that PI/r-based therapy is more often used than NNRTIs with statistical significance in patients with high viral load, Fig. A (≥100.000 copies/ml (58% vs 42%; OR:1,75; 95% CI: 1,26–2,43; p<0,01, with CD4 cell counts <200 cells/µl, Fig. B (68% vs 31%; OR: 2,92; 95% CI: 1,99–4,27; p<0,01, and in patients at CDC stage C (65% vs 35%; OR: 2,05; CI: 1,27–3,31; p<0,01. Conclusions: In Spain, HIV is still diagnosed late (as measured by CD4 count<350 cells/µl. Treatment based on NNRTIs are more frequently used in naïve patients, although PIs

    Background Adherence is a strong determinant of viral suppression with antiretroviral therapy (ART), but measuring it is challenging. Medication delivery can be measured accurately in settings with computerized prescription databases. We studied the association between Medication Possession Ratio (MPR), virologic suppression, and resistance to ART in Côte d’Ivoire. Methods We conducted a prospective cohort study of HIV-1 infected adults initiating ART in three clinics using computerized monitoring systems. Patients had viral load (VL) tests at month 6 (M6) and month 12 (M12) after ART initiation, and genotype tests if VL was detectable (≥300 copies/ml). MPR was defined as the number of daily doses of antiretroviral drug actually provided divided by the total number of follow-up days since ART initiation. Results Overall, 1,573 patients started ART with stavudine/zidovudine plus lamivudine plus nevirapine/efavirenz. At M6 and M12, 996 and 942 patients were in active follow-up; 20% (M6) and 25% (M12) of patients had detectable VL, including 7% (M6) and 11% (M12) with ≥1 resistance mutation. Among patients with MPR ≥95%, 80–94%, 65–79%, 50–64% and <50% at M12, the proportion with detectable VL [resistance] was 9% [4%], 17% [7%], 45% [24%], 67% [31%], and 85% [37%]. Among patients with ≥1 mutation at M12, 86% were resistant to lamivudine/emtricitabine and/or nevirapine/efavirenz but not to other drugs. Conclusion MPR was strongly associated with virologic outcomes. Half of those with detectable VL at M12 had no resistance mutations. MPR should be used at M6 to identify patients who might benefit from early interventions to reinforce adherence. PMID:21191309

    Full Text Available BACKGROUND: Large HIV care programs frequently subsidize antiretroviral (ARV drugs and CD4 tests, but patients must often pay for other health-related drugs and services. We estimated the financial burden of health care for households with HIV-infected adults taking antiretroviral therapy (ART in Côte d'Ivoire. METHODOLOGY/PRINCIPAL FINDINGS: We conducted a cross-sectional survey. After obtaining informed consent, we interviewed HIV-infected adults taking ART who had consecutively attended one of 18 HIV care facilities in Abidjan. We collected information on socioeconomic and medical characteristics. The main economic indicators were household capacity-to-pay (overall expenses minus food expenses, and health care expenditures. The primary outcome was the percentage of households confronted with catastrophic health expenditures (health expenditures were defined as catastrophic if they were greater than or equal to 40% of the capacity-to-pay. We recruited 1,190 adults. Median CD4 count was 187/mm(3, median time on ART was 14 months, and 72% of subjects were women. Mean household capacity-to-pay was $213.7/month, mean health expenditures were $24.3/month, and 12.3% of households faced catastrophic health expenditures. Of the health expenditures, 75.3% were for the study subject (ARV drugs and CD4 tests, 24.6%; morbidity events diagnosis and treatment, 50.1%; transportation to HIV care centres, 25.3% and 24.7% were for other household members. When we stratified by most recent CD4 count, morbidity events related expenses were significantly lower when subjects had higher CD4 counts. CONCLUSIONS/SIGNIFICANCE: Many households in Côte d'Ivoire face catastrophic health expenditures that are not attributable to ARV drugs or routine follow-up tests. Innovative schemes should be developed to help HIV-infected patients on ART face the cost of morbidity events.

    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.

    2010-07-01

    Full Text Available R Chris Rathbun, Michelle D LiedtkeDepartment of Clinical and Administrative Sciences, College of Pharmacy, University of Oklahoma Health Sciences Center, Oklahoma City, USAAbstract: Etravirine is a second-generation nonnucleoside reverse transcriptase inhibitor (NNRTI that is approved for the treatment of adult human immunodeficiency virus (HIV-infected patients with documented or suspected resistance to first-generation NNRTIs. Etravirine has a flexible molecular structure that allows it to retain its activity against mutant HIV strains that exhibit resistance to first-generation agents. It is evident that 3 or more etravirine resistance-associated mutations are typically necessary before clinical resistance to etravirine. Safety and efficacy of etravirine are established in antiretroviral treatment-experienced patients in combination with antiretroviral regimens that contain darunavir/ritonavir. In phase III studies, cutaneous reactions occurred in 19% of treated patients and are the most commonly observed adverse event. The typical manifestation is the development of a maculopapular rash within the first few weeks of etravirine therapy. Resolution commonly occurs within 1–2 weeks on continued therapy. Rare cases of severe skin reactions (<0.1% have been reported. Etravirine is hepatically metabolized by cytochrome P450 (CYP 3A4, CYP2C9, and CYP2C19. Drug interactions with some antiretrovirals (eg, unboosted protease inhibitors and fosamprenavir/ritonavir and medications for other comorbidities (eg, atorvastatin and clarithromycin have been reported and may require dosage adjustment for the coadministered drug or selection of alternative therapy in some instances. Administration of etravirine with potent inducers of CYP450 is not recommended due to the potential for subtherapeutic etravirine concentrations. In this article, the pharmacology, efficacy, safety, and tolerability of etravirine in adult treatment-experienced patients with HIV-1

    Full Text Available This study profiled beach flags start kinematics for experienced young adult sprinters. Five males and three females (age = 20.8 ± 2.1 years; height = 1.70 ± 0.06 meters [m]; mass = 63.9 ± 6.0 kilograms completed four sprints using their competition start technique. A high-speed camera, positioned laterally, filmed the start. Data included: start time; hand clearance time; posterior movement from the start line; feet spacing during the start; elbow, hip, knee, trunk lean, and trajectory angles at take-off; and first step length. Timing gates recorded 0-2, 0-5, and 0-20 m time. Spearman's correlations identified variables relating (p < 0.05 to faster start and sprint times. The beach flags start involved sprinters moving 0.18 ± 0.05 m posterior to the start line by flexing both legs underneath the body before turning. Following the turn, the feet were positioned 0.47 ± 0.07 apart. This distance negatively correlated with start (ρ = -0.647, 0-2 (ρ = -0.683, and 0-5 m (ρ = -0.766 time. Beach flags start kinematics at take-off resembled research analyzing track starts and acceleration. The elbow extension angle (137.62 ± 13.45° of the opposite arm to the drive leg correlated with 0-2 (ρ = -0.762, 0-5 (ρ = -0.810, and 0-20 m (ρ = -0.810 time. Greater arm extension likely assisted with stability during the start, leading to enhanced sprint performance. The drive leg knee extension angle (146.36 ± 2.26° correlated with start time (ρ = -0.677, indicating a contribution to a faster start completion. A longer first step following the start related to faster 0-5 m time (ρ = -0.690. Sprinters quicker over 0-2 and 0-5 m were also quicker over 20 m (ρ = 0.881-0.952. Beach flags sprinters must ensure their start is completed quickly, such that they can attain a high speed throughout the race

    Full Text Available Complexity of antiretroviral treatment (ART is a reason for non-adherence and may impact treatment outcome. The association between daily dosing and pill burden and chance of virological success (VS of first ART has been rarely assessed. 3,674 naïve patients who started treatment after January 2000 were identified from the ICoNA cohort. Number of daily doses and pills were estimated on the basis of the drugs used to rank first ART complexity: 1–2 daily pills once a day (low-pills QD [lpQD]; 3–6 daily pills QD (high-pills QD [hpQD]; 2–5 daily pills BID (low-pills BID [lpBID]; >6 daily pills BID (high-pills BID [hpBID]. VS was the date of first HIV RNA <50 cp/ml. Follow-up was censored at the date of VS or last available HIV RNA. Kaplan-Meier curves estimated probability of achieving VS according to ART complexity. Univariable and multivariable Cox regression stratified by clinical site was used to identify variables associated with VS. ITT principle was applied, using competing risk approach for death. Population: male 75%; median age 37 y (IQR, 32–44; HIV transmission heterosexual 43%, homosexual 33%, drug use 16%; Italian origin 86%; CDC group C 17%; median pre-ART CD4 and log HIV-RNA were 271/mm3 (range, 0–1672 and 4.84 cp/ml (1.70–6.38, respectively.

    Full Text Available BACKGROUND: There is limited evidence on the optimal timing of antiretroviral therapy (ART initiation in children 2-5 y of age. We conducted a causal modelling analysis using the International Epidemiologic Databases to Evaluate AIDS-Southern Africa (IeDEA-SA collaborative dataset to determine the difference in mortality when starting ART in children aged 2-5 y immediately (irrespective of CD4 criteria, as recommended in the World Health Organization (WHO 2013 guidelines, compared to deferring to lower CD4 thresholds, for example, the WHO 2010 recommended threshold of CD4 count <750 cells/mm(3 or CD4 percentage (CD4% <25%. METHODS AND FINDINGS: ART-naïve children enrolling in HIV care at IeDEA-SA sites who were between 24 and 59 mo of age at first visit and with ≥1 visit prior to ART initiation and ≥1 follow-up visit were included. We estimated mortality for ART initiation at different CD4 thresholds for up to 3 y using g-computation, adjusting for measured time-dependent confounding of CD4 percent, CD4 count, and weight-for-age z-score. Confidence intervals were constructed using bootstrapping. The median (first; third quartile age at first visit of 2,934 children (51% male included in the analysis was 3.3 y (2.6; 4.1, with a median (first; third quartile CD4 count of 592 cells/mm(3 (356; 895 and median (first; third quartile CD4% of 16% (10%; 23%.

    Full Text Available Background. Nevirapine- (NVP- based antiretroviral therapy (ART and artesunate-amodiaquine are frequently coprescribed in areas of HIV and malaria endemicity. We explored the impact of this practice on artesunate and dihydroartemisinin pharmacokinetics. Methods. We conducted a parallel-group pharmacokinetic comparison between HIV-infected patients receiving NVP-based ART (n=10 and ART-naive controls (n=11. Artesunate-amodiaquine 200/600 mg was given daily for three days. Measurement of drug concentrations occurred between 0 and 96 hours after the final dose. Pharmacokinetic parameters were determined using noncompartmental analysis. Results. Comparing the NVP group to controls, clearance of artesunate was reduced 50% (1950 versus 2995 L/h; P=0.03, resulting in a 45% increase in the AUC0-96 (105 versus 69 ug∗hr/L; P=0.02. The half-life of dihydroartemisinin was shorter in the NVP group (1.6 versuss 3.2 h; P=0.004, but other dihydroartemisinin pharmacokinetic parameters were unchanged. A lower conversion of artesunate to dihydroartemisinin was observed in the NVP group (dihydroartemisinin: artesunate AUC0-96=5.6 versuss 8.5 in NVP and control groups, respectively, P=0.008. Conclusion. Although NVP-containing ART impacted some pharmacokinetic parameters of artesunate and dihydroartemisinin, overall exposure was similar or better in the NVP group.

    The update of these adult antiretroviral treatment (cART) recommendations has been carried out by consensus of a panel consisting of members of the Grupo de Estudio de Sida (Gesida, AIDS Study Group) and the Plan Nacional sobre el Sida (PNS, Spanish AIDS Plan) who have reviewed the antiretroviral efficacy and safety advances in clinical trials, cohort and pharmacokinetic studies published in medical journals (PubMed and Embase), or presented in medical scientific meetings. Three levels of evidence were defined according to the data source: randomized studies (level A), cohort or case-control studies (level B), and expert opinion (level C). The decision to recommend, consider or not to recommend antiretroviral treatment (ART) was established by consensus in each situation. The current treatment of choice for HIV infection is the combination of three drugs. Combined ART is recommended in patients with symptomatic HIV infection, and guidelines on this treatment in patients with an opportunistic type C infection are included. In asymptomatic patients, initiation of ART is recommended on the basis of CD4 lymphocyte counts, plasma viral load and patient co-morbidities, as follows: a) therapy should be started in patients with CD4 counts cells/μL; b) Therapy should be recommended when CD4 counts are between 350 and 500 cells/μL, except when CD4 are stabilized, there is low plasma viral load, or the patient not willing; c) Therapy could be deferred when CD4 counts are above 500 cells/ μL, but should be considered in cases of cirrhosis, chronic hepatitis C, hepatitis B fulfilling treatment criteria, high cardiovascular risk, HIV nephropathy, viral load > 100,000 copies/ mL, proportion of CD4 cells 55 years, and in cases of discordant serological sexual couples in order to reduce transmission. cART should include 2 reverse transcriptase inhibitor nucleoside analogues (AN) and a non-analogue reverse transcriptase inhibitor (NN) or 2 AN and a ritonavir boosted protease

    Full Text Available Abstract Background Antiretroviral therapy (ART clinic populations have expanded enormously in the successful Malawi ART scale-up programme. Overcrowding, long waiting times and living far away from the clinic may affect the extent to which patients use their ART clinic for intercurrent illnesses. Methods We interviewed patients of a large urban ART clinic in Blantyre, Malawi, during routine visits about the choice of health care facility during recent illness episodes. Results Out of 346 enrolled adults, mean age 39.8 (range 18-70 years, 54.3% female, 202 (58% reported one or more illness in the past 6 months, during which 85 (42.1%; 95%-confidence interval: 36.9-47.3% did not utilize their own clinic. Long distance to the clinic was the main subjective reason, while low education attainment, rural residence, perceived mild illness and dissatisfaction with the ART service were associated with not using their own clinic in multivariate analyses. Of all participants, 83.6% were satisfied with the service provided; only 6.1% were aware of the full service package of the ART clinic. Conclusions ART patients often seek health care outside their own clinic, which may have detrimental effects, and has consequences for ART counseling content and reporting of ART information in health passports.

    Most adults firmly believe that as kids reach their teens, they start to take crazy risks that get them in trouble. Motivated to protect teenagers, adults impose age limits on what they consider to be really dangerous activities. But do teenagers simply love taking all risks much more than adults? Our research suggests otherwise. When the risks are vague, adolescents indeed are very optimistic about their odds and much more likely to take risks than adults. However, teenagers who understand t...

    Most HIV positive people have not been tested for viral hepatitis and their treatments have not been optimized for possible co-infections. The aim of this study was to investigate the serological pattern of hepatitis B virus (HBV) and hepatitis C virus (HCV) infections among antiretroviral (ARV)-naive and -experienced HIV co-infected adults in Addis Ababa, Ethiopia. A total of 500 frozen HIV positive serum and plasma samples collected from ARV-naive (n = 250) and -experienced (n = 250) adults were randomly selected and screened for HBsAg, anti-HBs, HBeAg and anti-HCV using rapid two-site sandwich immunochromatographic assay. The test was performed at Aklilu Lemma Institute of Pathobiology, Addis Ababa University. Positive specimens for HBsAg and anti-HCV markers were further confirmed using third generation ELISA. Of the 500 specimens tested, 15 (3 %), 58 (11.6 %), 3 (0.6 %), 18 (3.6 %), 3 (0.6 %) and 1 (0.2 %) were positive for HBsAg, anti-HBs, HBeAg, anti-HCV, HBsAg and HBeAg, and HBsAg and anti-HBs markers, respectively. No specimen tested positive for both HBeAg and anti-HBs, and 442 (88.4 %) individuals were non-immune to HBV. Of the 250 ARV-naive individuals, 8 (3.2 %), 33 (13.2 %), 2 (0.8 %), 10 (4 %), 2 (0.8 %), and 1 (0.4 %) were positive for HBsAg, anti-HBs, HBeAg, anti-HCV, HBsAg and HBeAg, and HBsAg and anti-HBs markers, respectively. Of the 250 ARV-experienced individuals, 7 (2.8 %), 25 (10 %), 1 (0.4 %), 8 (3.2 %), 1 (0.4 %), and 0 (0 %) were positive for HBsAg, Anti-HBs, HBeAg, anti-HCV, HBsAg and HBeAg, and HBsAg and anti-HBs markers, respectively. In summary, seroprevalence of HIV/HBV and HIV/HCV co-infections was lower in Addis Ababa, Ethiopia, than in Sub-Saharan Africa and globally. HBV and HCV infections were not significantly different between HIV positive subjects who were or who were not on ARV. This suggests that the two groups have equal chance of being infected with these two viruses; despite

    In October 2010, it will be exactly 25 years ago that the first antiretroviral drug, AZT (zidovudine, 3'-azido-2',3'-dideoxythymidine), was described. It was the first of 25 antiretroviral drugs that in the past 25 years have been formally licensed for clinical use. These antiretroviral drugs fall into seven categories [nucleoside reverse transcriptase inhibitors (NRTIs), nucleotide reverse transcriptase inhibitors (NtRTIs), non-nucleoside reverse transcriptase inhibitors (NNRTIs), protease inhibitors (PIs), fusion inhibitors (FIs), co-receptor inhibitors (CRIs) and integrase inhibitors (INIs). The INIs (i.e. raltegravir) represent the most recent advance in the search for effective and selective anti-HIV agents. Combination of several anti-HIV drugs [often referred to as highly active antiretroviral therapy (HAART)] has drastically altered AIDS from an almost uniformly fatal disease to a chronic manageable one.

We used qualitative methods to explore the use, perceptions, and acceptability of RUSF among adult HIV patients in Jimma, Ethiopia. Methods: The study obtained data from direct observations and 24 in-depth interviews with HIV patients receiving RUSF. Results: Participants were generally very motivated to take RUSF and viewed it as beneficial. RUSF was described as a means to fill a nutritional gap, to “rebuild the body,” and protect it from harmful effects of antiretroviral treatment (ART. Many experienced nausea and vomiting when starting the supplement. This caused some to stop supplementation, but the majority adapted to RUSF. The supplement was eaten separately from meal situations and only had a little influence on household food practices. RUSF was described as food with “medicinal qualities,” which meant that many social and religious conventions related to food did not apply to it. The main concerns about RUSF related to the risk of HIV disclosure and its social consequences. Conclusion: HIV patients view RUSF in a context of competing livelihood needs. RUSF intake was motivated by a strong wish to get well, while the risk of HIV disclosure caused concerns. Despite the motivation for improving health, the preservation of social networks was prioritized, and nondisclosure was often a necessary strategy. Food sharing and religious

    Full Text Available Clinical depression is a highly debilitating illness, which is often under-diagnosed and negatively impacts on the quality of life of its sufferers. When it co-exists with other medical conditions, its effect is even more incapacitating. Undiagnosed depression in the context of HIV infection leads to accelerated decline in CD4+ cell counts with concomitant increase in the viral load and poor adherence to the antiretroviral medications which lead to viral mutation and the evolution of resistant strains. This study examined the prevalence of depression, its correlates and the frequency of the diagnosis of the condition among HIV+ subjects on highly active antiretroviral therapy (HAART by the internists and general physicians at the University of Maiduguri Teaching Hospital in Northeastern Nigeria. Three hundred and fifty representative samples of HIV+ adults on HAART were drawn from the Antiretroviral Therapy Clinic of the Institution. Diagnosis of depression was made using the International Classification of Diseases-10 criteria based on Composite International Diagnostic Interview generated data. Socio-demographic and clinical variables were also analyzed for their correlation with depression in the subjects. About 20% of the respondents were diagnosed with clinical depression and no diagnosis of the condition was hitherto entertained in all the respondents. The independent determinants of depression in the participants were: female gender [odds ratio (OR=3.87 (95% confidence interval, CI: 2.089-7.183], past history of psychiatric illness [OR=43.81 (95% CI: 9.731-197.30] and family history of psychiatric illness in first-degree relatives of the subjects [OR=14.364 (95% CI=5.327- 38.729]. Depression is a relatively common psychiatric condition among adults on HAART, there is therefore the need for routine screening of this condition among HIV+ subjects in order to optimize patient care and improve clinical outcomes.

    Background. Low body mass index (BMI) at antiretroviral therapy (ART) initiation is associated with early mortality, but the etiology is not well understood. We hypothesized that low pretreatment serum phosphate, a critical cellular metabolism intermediate primarily stored in skeletal muscle, may predict mortality within the first 12 weeks of ART. Methods. We prospectively studied 352 HIV-infected adults initiating ART in Lusaka, Zambia to estimate the odds of death for each 0.1 mmol/L decrease in baseline phosphate after adjusting for established predictors of mortality. Results. The distribution of phosphate values was similar across BMI categories (median value 1.2 mmol/L). Among the 145 participants with BMI refeeding syndrome. Further studies of cellular metabolism in this population are needed.

    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 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.

    HIV-infected patients receiving antiretroviral therapy have increased risk of metabolic syndrome, including dyslipidemia. In this study, we determined whether individual nutritional counseling reduced dyslipidemia, particularly low-density lipoprotein (LDL) cholesterol, among HIV-infected patients with dyslipidemia not currently taking lipid-lowering medication. We conducted a randomized 24-week trial among HIV-infected patients with dyslipidemia who were on antiretroviral therapy and were eligible to initiate therapeutic lifestyle changes according to the Thai National Cholesterol Education Program. Participants were randomly assigned to an intervention group that received individual counseling with a nutritionist for seven sessions (baseline, weeks 2, 4, 8, 12, 18, and 24) and a control group that received standard verbal diet information at baseline and nutritional counseling only at week 24. A 24-h recall technique was used to assess dietary intake for both groups at baseline and week 24. Lipid profile (total cholesterol, LDL, high-density lipoprotein (HDL), and triglyceride) was measured at baseline and after 12 and 24 weeks of therapy. An intention-to-treat and linear mixed model were used. Seventy-two patients were randomly assigned, and 62 (86%) participants completed their lipid profile test. After 12 weeks of follow-up, there were significant reductions in the intervention group for total cholesterol (-14.4 ± 4.6 mg/dL, P = .002), LDL cholesterol (-13.7 ± 4.1 mg/dL, P = .001), and triglyceride (-30.4 ± 13.8 mg/dL, P = .03). A significant reduction in LDL cholesterol was also observed in the control group (-7.7 ± 3.8 mg/dL, P = .04), but there were no significant differences in change of mean lipid levels between the groups at 12 weeks of follow-up. After 24 weeks, participants assigned to the intervention group demonstrated significantly greater decreases in serum total cholesterol (-19.0 ± 4.6 vs. 0.2

    Patients with human immunodeficiency virus type 1 (HIV-1) infection are at high risk of developing Epstein-Barr virus (EBV)-associated lymphoma. However, little is known of the EBV DNA loads in patients receiving highly active antiretroviral therapy (HAART). Using a real-time quantitative polymerase chain reaction assay, we demonstrated that significantly more HIV-1-infected patients receiving HAART than HIV-1-uninfected volunteers had detectable EBV DNA in blood (57 [81%] of 70 vs. 11 [16%] of 68 patients; P=.001) and saliva (55 [79%] of 68 vs. 37 [54%] of 68 patients; P=.002). The mean EBV loads in blood and saliva samples were also higher in HIV-1-infected patients than in HIV-1-uninfected volunteers (P=.001). The frequency of EBV detection in blood was associated with lower CD4+ cell counts (P=.03) among HIV-1-infected individuals, although no differences were observed in the EBV DNA loads in blood or saliva samples in the HIV-1-infected group. Additional studies are needed to determine whether EBV-specific CD4+ and CD8+ cells play a role in the pathogenesis of EBV in HIV-1-infected patients receiving HAART.

    Adherence to antiretroviral therapy (ART) is crucial for thwarting HIV disease progression and reducing secondary HIV transmission, yet youth living with HIV (YLH) struggle with adherence. The highest rates of new HIV infections in the United States occur in young African American men. A sample of 387 HIV-positive young African American males on ART was selected from a cross-sectional assessment of (YLH) receiving medical care within the Adolescent Trials Network for HIV/AIDS Interventions (ATN) from 2010 to 2012 (12-24 years old, median 22.00, SD 2.08). Participants completed self-reported adherence, demographic, health, and psychosocial measures. Sixty-two percent self-reported 100% ART adherence. Optimal data analysis identified frequency of cannabis use during the past 3 months as the strongest independent predictor of adherence, yielding moderate effect strength sensitivity (ESS) = 27.1, p psychological distress and minimal alcohol use (82% were adherent). Participants least likely to be adherent were those with higher psychological distress and engaged in weekly cannabis use (69% were nonadherent). Findings suggest multiple profiles of ART adherence for young African American males living with HIV and argue for targeted psychosocial interventions. PMID:27410496

    Full Text Available Abstract Background The World Health Organization (WHO has recently recommended that antiretrovirals be initiated in all individuals with CD4 counts of less than 350 cells/mm3. For countries with resources too limited to expand care to all such patients, it would be of value to able to identify and target populations at highest risk of HIV progression. Renal disease has been identified as a risk factor for disease progression or death in some populations. Methods Times to meeting combination antiretroviral therapy (cART initiation criteria (developing either a CD4 count 3 or WHO stage 3 or 4 disease and overall mortality were evaluated in cART-naïve, HIV-infected Kenyan adults with CD4 cell counts ≥200/mm3 and with WHO stage 1 or 2 disease. Cox proportional hazard regression models were used to evaluate the associations between renal function and these endpoints. Results We analyzed data of 7383 subjects with a median follow-up time of 59 (interquartile range, 27-97 weeks. In Cox regression analyses adjusted for age, sex, WHO disease stage, CD4 cell count and haemoglobin, estimated creatinine clearance (CrCl 2 was associated with shorter times to meeting cART initiation criteria (HR 1.39; 95% CI, 1.22-1.58, but not with overall mortality. CrCl and eGFR remained associated with shorter times to cART initiation criteria, but neither was associated with mortality, in weight-adjusted analyses. Conclusions In this large natural history study, reduced renal function was strongly associated with faster HIV disease progression in adult Kenyans not initially meeting cART initiation criteria. As such, renal function measurement in resource-limited settings may be an inexpensive method to identify those most in need of cART to prevent progression to AIDS. The initial association between reduced CrCl, but not reduced eGFR, and greater mortality was explained by the low weights in this population.

    Full Text Available To determine the frequency and patterns of acquired antiretroviral drug resistance in a rural primary health care programme in South Africa.Cross-sectional study nested within HIV treatment programme.Adult (≥ 18 years HIV-infected individuals initially treated with a first-line stavudine- or zidovudine-based antiretroviral therapy (ART regimen and with evidence of virological failure (one viral load >1000 copies/ml were enrolled from 17 rural primary health care clinics. Genotypic resistance testing was performed using the in-house SATuRN/Life Technologies system. Sequences were analysed and genotypic susceptibility scores (GSS for standard second-line regimens were calculated using the Stanford HIVDB 6.0.5 algorithms.A total of 222 adults were successfully genotyped for HIV drug resistance between December 2010 and March 2012. The most common regimens at time of genotype were stavudine, lamivudine and efavirenz (51%; and stavudine, lamivudine and nevirapine (24%. Median duration of ART was 42 months (interquartile range (IQR 32-53 and median duration of antiretroviral failure was 27 months (IQR 17-40. One hundred and ninety one (86% had at least one drug resistance mutation. For 34 individuals (15%, the GSS for the standard second-line regimen was <2, suggesting a significantly compromised regimen. In univariate analysis, individuals with a prior nucleoside reverse-transcriptase inhibitor (NRTI substitution were more likely to have a GSS <2 than those on the same NRTIs throughout (odds ratio (OR 5.70, 95% confidence interval (CI 2.60-12.49.There are high levels of drug resistance in adults with failure of first-line antiretroviral therapy in this rural primary health care programme. Standard second-line regimens could potentially have had reduced efficacy in about one in seven adults involved.

    Stavudine is no longer recommended for use in first-line antiretroviral therapy (ART), but it remains in high demand worldwide because it is affordable. We report the clinical presentation and incidence of severe hyperlactatemia (SL) in HIV-infected adults who initiated ART between April 2005 and May 2009 in Côte d'Ivoire, West Africa. In a prospective cohort study at the HIV care center affiliated with the National Centre for Blood Transfusion, we used standardized forms to record baseline and follow-up data. We measured serum lactate levels for all adults on ART who showed signs of hyperlactatemia. SL was defined as serum lactate >2.5 mmol/liter. Overall, 806 adults initiated ART. Among the 591 patients (73%) on stavudine-containing regimens, 394 were women (67%); the median pre-ART CD4 count was 150/mm3 and the median body mass index was 20.9 kg/m2. These patients were followed for a median of 28 months. We detected SL only among patients taking stavudine. The incidence of SL was 0.55/100 person-years (PY) (95% CI 0.47-0.63) overall and 0.85/100 PY among women (95% CI 0.75-0.95). Among the eight patients with SL, 100% lost >9% of body weight before diagnosis, 100% had serum lactate >4 mmol/liter (range 4.2-12.1), 50% had pre-ART BMI >25 kg/m2, and three patients died (38%), accounting for 6.4% of deaths among patients taking stavudine. As long as HIV clinicians continue to use stavudine in sub-Saharan Africa, they should watch out for acute unexplained weight loss in patients taking ART, particularly among women and patients with high pre-ART BMI.

    Marta C Nunes

    Full Text Available BACKGROUND: Highly active antiretroviral treatment (HAART programs have been associated with declines in the burden of invasive pneumococcal disease (IPD in industrialized countries. The aim of this study was to evaluate trends in IPD hospitalizations in HIV-infected adults in Soweto, South Africa, associated with up-scaling of the HAART program from 2003 to 2008. METHODS: Laboratory-confirmed IPD cases were identified from 2003 through 2008 through an existing surveillance program. The period 2003-04 was designated as the early-HAART era, 2005-06 as the intermediate-HAART era and 2007-08 as the established-HAART era. The incidence of IPD was compared between the early-HAART and established-HAART eras in HIV-infected and-uninfected individuals. RESULTS: A total of 2,567 IPD cases among individuals older than 18 years were reported from 2003 through 2008. Overall incidence of IPD (per 100,000 did not change during the study period in HIV-infected adults (207.4 cases in the early-HAART and 214.0 cases in the established-HAART era; p = 0.55. IPD incidence, actually increased 1.16-fold (95% CI: 1.01; 1.62 in HIV-infected females between the early-and established-HAART eras (212.1 cases and 246.2 cases, respectively; p = 0.03. The incidence of IPD remained unchanged in HIV-uninfected adults across the three time periods. CONCLUSION: Despite a stable prevalence of HIV and the increased roll-out of HAART for treatment of AIDS patients in our setting, the burden of IPD has not decreased among HIV-infected adults. The study indicates a need for ongoing monitoring of disease and HAART program effectiveness to reduce opportunistic infections in African adults with HIV/AIDS, as well as the need to consider alternate strategies including pneumococcal conjugate vaccine immunization for the prevention of IPD in HIV-infected adults.

    Health-related quality of life (HRQoL) is an important outcome measure among HIV-infected patients receiving combination antiretroviral therapy (cART), but has not been studied extensively in resource-limited settings. Insight in the predictors or correlates of poor HRQoL may be helpful to identify patients most in need of additional support and to design appropriate interventions. A cross-sectional study was conducted between September 2012 and April 2013 in 10 healthcare facilities in Addis Ababa, Ethiopia. Patients who were at least 6 months on cART were randomly selected and individual patient data were retrieved from medical records. HRQoL was measured by the WHOQoL-HIVBREF, depressive-symptoms by the Kessler-6 scale, and stigma by the Kalichman internalized AIDS-related stigma scale. Multivariate linear regression analysis was carried-out to examine associations between HRQoL and the other variables. A total of 664 patients (response-rate 95%) participated in the study. A higher level of depressive-symptoms was most strongly and consistently associated with a lower HRQoL, both in terms of the magnitude of the relationship and in the number of HRQoL domains associated with it. Also, a higher level of HIV-stigma was associated with a lower HRQoL except for the physical domain, while obtaining sufficient nutritious food and job opportunity were associated with a better HRQoL except for the spiritual and social domains, respectively. Demographics, clinical, and treatment characteristics yielded few significant associations with HRQoL. Our study findings suggest that interventions to improve HRQoL should focus on reducing depressive-symptoms and HIV-stigma, and on enhancing food security and job opportunity. PMID:25782603

    This consensus document has been prepared by a panel consisting of members of the AIDS Study Group (Gesida) and the Spanish Secretariat for the National Plan on AIDS (SPNS) after reviewing the efficacy and safety results of clinical trials, cohort and pharmacokinetic studies published in medical journals, or presented in medical scientific meetings. Gesida has prepared an objective and structured method to prioritise combined antiretroviral treatment (cART) in naïve patients. Recommendations strength (A, B, C) and the evidence which supports them (I, II, III) are based on a modification of the Infectious Diseases Society of America criteria. The current antiretroviral treatment (ART) of choice for chronic HIV infection is the combination of three drugs. ART is recommended in patients with symptomatic HIV infection, in pregnancy, in serodiscordant couples with high transmission risk, hepatitis B fulfilling treatment criteria, and HIV nephropathy. Guidelines on ART treatment in patients with concurrent diagnosis of HIV infection and an opportunistic type C infection are included. In asymptomatic patients ART is recommended on the basis of CD4 lymphocyte counts, plasma viral load and patient co-morbidities, as follows: 1) therapy should be started in patients with CD4 counts cells/μL; 2) when CD4 counts are between 350 and 500 cells/μL, therapy will be recommended and only delayed if patient is reluctant to take it, the CD4 are stabilised, and the plasma viral load is low; 3) therapy could be deferred when CD4 counts are above 500 cells/μL, but should be considered in cases of cirrhosis, chronic hepatitis C, high cardiovascular risk, plasma viral load >10(5) copies/mL, proportion of CD4 cells 55 years. ART should include 2 reverse transcriptase inhibitors nucleoside analogues and a third drug (non-analogue reverse transcriptase inhibitor, ritonavir boosted protease inhibitor or integrase inhibitor). The panel has consensually selected and given priority to using

    Background.  Despite the benefits of antiretroviral therapy (ART), tuberculosis (TB) is the leading cause of mortality among human immunodeficiency virus (HIV)-infected persons in Africa. Nigeria bears the highest TB burden in Africa and second highest HIV burden globally. This long-term multicenter study aimed to determine the incidence rate and predictors of TB in adults in the Harvard/AIDS Prevention Initiative in Nigeria (APIN) and President's Emergency Plan for AIDS Relief (PEPFAR) Nigeria ART program. Methods.  This retrospective evaluation used data collected from 2004 to 2012 through the Harvard/APIN PEPFAR program. Risk factors for incident TB were determined using multivariate Cox proportional hazards regression with time-dependent covariates. Results.  Of 50 320 adults enrolled from 2005 to 2010, 11 092 (22%) had laboratory-confirmed active TB disease at ART initiation, and 2021 (4%) developed active TB after commencing ART. During 78 228 total person-years (PY) of follow-up, the TB incidence rate was 25.8 cases per 1000 PY (95% confidence interval [CI], 24.7-27.0) overall, and it decreased significantly both with duration on ART and calendar year. Risk factors at ART initiation for incident TB included the following: earlier ART enrollment year, tenofovir-containing initial ART regimen, and World Health Organization clinical stage above 1. Time-updated risk factors included the following: low body mass index, low CD4(+) cell count, unsuppressed viral load, anemia, and ART adherence below 80%. Conclusions.  The rate of incident TB decreased with longer duration on ART and over the program years. The strongest TB risk factors were time-updated clinical markers, reinforcing the importance of consistent clinical and laboratory monitoring of ART patients in prompt diagnosis and treatment of TB and other coinfections.

    Routine HIV viral load (VL) monitoring is the standard of care for persons receiving antiretroviral therapy (ART) in developed countries. Although the World Health Organization recommends annual VL monitoring of patients on ART, recognizing difficulties in conducting routine VL testing, the WHO continues to recommend targeted VL testing to confirm treatment failure for persons who meet selected immunologic and clinical criteria. Studies have measured positive predictive value (PPV), negative predictive value, sensitivity and specificity of these criteria among patients receiving first-line ART but not specifically among those on second-line or subsequent regimens. Between 2008 and 2011, adult ART patients in Nyanza, Kenya who met national clinical or immunologic criteria for treatment failure received targeted VL testing. We calculated PPV and 95% confidence intervals (CI) of these criteria to detect virologic treatment failure among patients receiving a) first-line ART, b) second/subsequent ART, and c) any regimen. Of 12,134 patient specimens tested, 2,874 (23.7%) were virologically confirmed as treatment failures. The PPV for 2,834 first-line ART patients who met either the clinical or immunologic criteria for treatment failure was 34.4% (95% CI 33.2–35.7), 33.1% (95% CI 24.7–42.3) for the 40 patients on second-line/subsequent regimens, and 33.4% (95% CI 33.1–35.6) for any ART. PPV, regardless of criteria, for first-line ART patients was lowest among patients over 44 years old and highest for patients aged 15 to 34 years. PPV of immunological and clinical criteria for correctly identifying treatment failure was similarly low for adult patients receiving either first-line or second-line/subsequent ART regimens. Our data confirm the inadequacy of clinical and immunologic criteria to correctly identify treatment failure and support the implementation of routine VL testing. PMID:27383834

    Full Text Available BACKGROUND: Generalizable data are needed on the magnitude and determinants of adherence and virological suppression among patients on antiretroviral therapy (ART in Africa. METHODS: We conducted a cross-sectional survey with chart abstraction, patient interviews and site assessments in a nationally representative sample of adults on ART for 6, 12 and 18 months at 20 sites in Rwanda. Adherence was assessed using 3- and 30-day patient recall. A systematically selected sub-sample had viral load (VL measurements. Multivariable logistic regression examined predictors of non-perfect (40 copies/ml. RESULTS: Overall, 1,417 adults were interviewed and 837 had VL measures. Ninety-four percent and 78% reported perfect adherence for the last 3 and 30 days, respectively. Eighty-three percent had undetectable VL. In adjusted models, characteristics independently associated with higher odds of non-perfect 30-day adherence were: being on ART for 18 months (vs. 6 months; younger age; reporting severe (vs. no or few side effects in the prior 30 days; having no documentation of CD4 cell count at ART initiation (vs. having a CD4 cell count of <200 cells/µL; alcohol use; and attending sites which initiated ART services in 2003-2004 and 2005 (vs. 2006-2007; sites with ≥600 (vs. <600 patients on ART; or sites with peer educators. Participation in an association for people living with HIV/AIDS; and receiving care at sites which regularly conduct home-visits were independently associated with lower odds of non-adherence. Higher odds of having a detectable VL were observed among patients at sites with peer educators. Being female; participating in an association for PLWHA; and using a reminder tool were independently associated with lower odds of having detectable VL. CONCLUSIONS: High levels of adherence and viral suppression were observed in the Rwandan national ART program, and associated with potentially modifiable factors.

    Full Text Available Little is known about the prevalence and burden of HIV associated neurocognitive disorder (HAND among patients on combination antiretroviral therapy (cART in sub-Saharan Africa. We estimated the prevalence of HAND in adult Malawians on cART and investigated the relationship between HAND and adherence to cART.HIV positive adults in Blantyre, Malawi underwent a full medical history, neurocognitive test battery, depression score, Karnofsky Performance Score and adherence assessment. The Frascati criteria were used to diagnose HAND and the Global Deficit Score (GDS was also assessed. Blood was drawn for CD4 count and plasma nevirapine and efavirenz concentrations. HIV negative adults were recruited from the HIV testing clinic to provide normative scores for the neurocognitive battery.One hundred and six HIV positive patients, with median (range age 39 (18-71 years, 73% female and median (range CD4 count 323.5 (68-1039 cells/µl were studied. Symptomatic neurocognitive impairment was present in 15% (12% mild neurocognitive disorder [MND], 3% HIV associated dementia [HAD]. A further 55% fulfilled Frascati criteria for asymptomatic neurocognitive impairment (ANI; however factors other than neurocognitive impairment could have confounded this estimate. Neither the symptomatic (MND and HAD nor asymptomatic (ANI forms of HAND were associated with subtherapeutic nevirapine/efavirenz concentrations, adjusted odds ratio 1.44 (CI. 0.234, 8.798; p = 0.696 and aOR 0.577 (CI. 0.09, 3.605; p = 0.556 respectively. All patients with subtherapeutic nevirapine/efavirenz levels had a GDS of less than 0.6, consistent with normal neurocognition.Fifteen percent of adult Malawians on cART had a diagnosis of MND or HAD. Subtherapeutic drug concentrations were found exclusively in patients with normal neurocognitive function suggesting HAND did not affect cART adherence. Further study of HAND requires more robust locally derived normative neurocognitive values and

    Full Text Available Introduction: Worldwide, HIV-related mortality among adolescents living with HIV (ALHIV increased by 50% from 2005 to 2012 and is attributed in part to a lack of support for adolescent retention to care and adherence to antiretroviral therapy (ART. This vulnerability reinforces the need to better understand incomplete ART adherence among ALHIV, particularly in sub-Saharan Africa, where the majority of the world's 2.1 million ALHIV reside. Methods: From December 2011 to February 2012, we conducted in-depth interviews with 32 ALHIV (aged 15 to 18 and 23 of their adult caregivers in the Copperbelt Province of Zambia. Interviews were transcribed and translated. An iterative qualitative process was used to code and analyze the data and main themes were summarized regarding the barriers to and facilitators of ART adherence. Results: More than a quarter of ALHIV reported missing a day or more of ART (ranging from one day to six months. Barriers to ART adherence included fear of disclosure and anticipated stigma. Few youth were willing to take their drugs outside of the home, which led to missed doses of ART. Similarly, families tended to manage HIV within the home only. As a result, although caregivers and families were often the greatest source of emotional and instrumental support, they coped with HIV in isolation of other potential support from their communities, schools or churches. Factors that supported ART adherence included attending clinic-sponsored youth groups, wanting to maintain one's health and using phone and clock alarms. Involvement of adult caregivers in HIV management varied greatly and was often based on the age and health status of the youth. Some caregivers struggled with letting the adolescents assume responsibility for their medication, and ALHIV had few self-management skills and tools to help them regularly take ART. Conclusions: These data highlight the importance of families and home environments in supporting adherence to

    Perceived social standing (PSS) was evaluated as a determinant of differences in health outcomes among Ugandan HIV-infected adults from Kampala using cross-sectional study design. PSS was defined using the MacArthur scale of subjective social status translated and adapted for the study setting. Socio-demographic and psychosocial correlates of PSS ranking at enrollment were determined using linear regression models. High versus low PSS was defined based on the median PSS score and evaluated as a determinant of body mass index, hemoglobin, quality of life (QOL) and frailty-related phenotype via linear regression. A log-binomial regression model estimated the relative-risk of good, very good or excellent versus fair or poor self-rated health (SRH) in relation to PSS. Older age, increasing social support and material wealth were correlated with high PSS ranking, whereas female sex, experience of multiple stigmas and multiple depressive symptoms were correlated with low PSS ranking. High PSS participants were on average 1.1 kg/m(2) heavier, had 4.7 % lower frailty scores and 3.6 % higher QOL scores compared to low PSS patients (all p management, combined with efforts to reduce stigma and improve social support, may identify and possibly reduce PSS-associated health inequality in Ugandan adults with HIV.

    Full Text Available BACKGROUND: Antiretroviral therapy (ART has been life saving for hundreds of thousands of Ethiopians. With increased availability of ART in recent years, achievement of optimal adherence and patient retention are becoming the greatest challenges in the management of HIV/AIDS in Ethiopia. However, few studies have explored factors influencing medication adherence to ART and retention in follow-up care among adult Ethiopian HIV-positive patients, especially in the Amhara region of the country, where almost one-third of the country's ART is prescribed. The aim of this qualitative study was to collect such data from patients and healthcare providers in the Amhara region of Ethiopia. METHODS: Semi-structured interviews were conducted with 24 patients, of whom 11 had been lost to follow-up and were non-persistent with ART. In addition, focus group discussions were performed with 15 ART nurses and 19 case managers. All interviews and focus groups were audio-recorded, transcribed, and coded for themes and patterns in Amharic using a grounded theory approach. The emergent concepts and categories were translated into English. RESULTS: Economic constraints, perceived stigma and discrimination, fasting, holy water, medication side effects, and dissatisfaction with healthcare services were major reasons for patients being non-adherent and lost to follow-up. Disclosure of HIV status, social support, use of reminder aids, responsibility for raising children, improved health on ART, and receiving education and counseling emerged as facilitators of adherence to ART. CONCLUSIONS: Improving adherence and retention requires integration of enhanced treatment access with improved job and food security. Healthcare providers need to be supported to better equip patients to cope with the issues associated with ART. Development of social policies and cooperation between various agencies are required to facilitate optimal adherence to ART, patient retention, and improved

    Background We previously published systematic reviews of retention in care after antiretroviral therapy initiation among general adult populations in sub-Saharan Africa. We estimated 36-month retention at 73% for publications from 2007–2010. This report extends the review to cover 2008–2013 and expands it to all low- and middle-income countries. Methods We searched PubMed, Embase, Cochrane Register, and ISI Web of Science from January 1, 2008 to December 31, 2013 and abstracts from AIDS and IAS from 2008–2013. We estimated retention across cohorts using simple averages and interpolated missing times through the last time reported. We estimated all-cause attrition (death, loss to follow-up) for patients receiving first-line ART in routine settings in low- and middle-income countries. Results We found 123 papers and abstracts reporting retention for 154 patient cohorts and 1,554,773 patients in 42 countries. Overall, 43% of all patients not retained were known to have died. Unweighted averages of reported retention was 78%, 71% and 69% at 12, 24, and 36 months after treatment initiation, respectively. We estimated 36-month retention at 65% in Africa, 80% in Asia, and 64% in Latin America and the Caribbean. From lifetable analysis, we estimated retention at 12, 24, 36, 48 and 60 months at 83%, 74%, 68%, 64% and 60%, respectively. Conclusions Retention at 36 months on treatment averages 65–70%. There are several important gaps in the evidence-base, which could be filled by further research, especially in terms of geographic coverage and duration of follow-up. PMID:25942461

    It is known that transmitted drug resistance (TDR) will most likely emerge in regions where antiretroviral therapy (ART) has been widely available for years. However, after a decade of rapid scale-up of ART in China, there are few data regarding TDR among HIV-infected patients prior to initiating first-line ART in China. A prospective, observational cohort study was performed at sentinel sites in five provinces or municipalities. Study participants were recruited at the county- or city-level ...

    Background Despite effective antiretroviral treatment (ART), HIV-positive individuals are at increased risk of serious non-AIDS conditions (cardiovascular, liver and renal disease, and cancers), perhaps due in part to ongoing inflammation and/or coagulation. To estimate the potential risk reduction in serious non-AIDS conditions or death from any cause that might be achieved with treatments that reduce inflammation and/or coagulation, we examined associations of interleukin-6 (IL-6), D-dimer, and high-sensitivity C-reactive protein (hsCRP) levels with serious non-AIDS conditions or death in 3 large cohorts. Methods In HIV-positive adults on suppressive ART, associations of IL-6, D-dimer, and hsCRP levels at study entry with serious non-AIDS conditions or death were studied using Cox regression. Hazard ratios (HR) adjusted for age, gender, study, and regression dilution bias (due to within-person biomarker variability) were used to predict risk reductions in serious non-AIDS conditions or death associated with lower “usual” levels of IL-6 and D-dimer. Results Over 4.9 years of mean follow-up, 260 of the 3766 participants experienced serious non-AIDS conditions or death. IL-6, D-dimer and hsCRP were each individually associated with risk of serious non-AIDS conditions or death, HR = 1.45 (95% CI: 1.30 to 1.63), 1.28 (95% CI: 1.14 to 1.44), and 1.17 (95% CI: 1.09 to 1.26) per 2x higher biomarker levels, respectively. In joint models, IL-6 and D-dimer were independently associated with serious non-AIDS conditions or death, with consistent results across the 3 cohorts and across serious non-AIDS event types. The association of IL-6 and D-dimer with serious non-AIDS conditions or death was graded and persisted throughout follow-up. For 25% lower “usual” IL-6 and D-dimer levels, the joint biomarker model estimates a 37% reduction (95% CI: 28 to 46%) in the risk of serious non-AIDS conditions or death if the relationship is causal.

    Full Text Available BACKGROUND: Most adults infected with HIV achieve viral suppression within a year of starting combination antiretroviral therapy (cART. It is important to understand the risk of AIDS events or death for patients with a suppressed viral load. METHODS AND FINDINGS: Using data from the Collaboration of Observational HIV Epidemiological Research Europe (2010 merger, we assessed the risk of a new AIDS-defining event or death in successfully treated patients. We accumulated episodes of viral suppression for each patient while on cART, each episode beginning with the second of two consecutive plasma viral load measurements 500 copies/µl, the first of two consecutive measurements between 50-500 copies/µl, cART interruption or administrative censoring. We used stratified multivariate Cox models to estimate the association between time updated CD4 cell count and a new AIDS event or death or death alone. 75,336 patients contributed 104,265 suppression episodes and were suppressed while on cART for a median 2.7 years. The mortality rate was 4.8 per 1,000 years of viral suppression. A higher CD4 cell count was always associated with a reduced risk of a new AIDS event or death; with a hazard ratio per 100 cells/µl (95% CI of: 0.35 (0.30-0.40 for counts <200 cells/µl, 0.81 (0.71-0.92 for counts 200 to <350 cells/µl, 0.74 (0.66-0.83 for counts 350 to <500 cells/µl, and 0.96 (0.92-0.99 for counts ≥500 cells/µl. A higher CD4 cell count became even more beneficial over time for patients with CD4 cell counts <200 cells/µl. CONCLUSIONS: Despite the low mortality rate, the risk of a new AIDS event or death follows a CD4 cell count gradient in patients with viral suppression. A higher CD4 cell count was associated with the greatest benefit for patients with a CD4 cell count <200 cells/µl but still some slight benefit for those with a CD4 cell count ≥500 cells/µl.

    Full Text Available BACKGROUND: Smear-positive pulmonary TB is the most infectious form of TB. Previous studies on the effect of HIV and antiretroviral therapy on TB treatment outcomes among these highly infectious patients demonstrated conflicting results, reducing understanding of important issues. METHODS: All adult smear-positive pulmonary TB patients diagnosed between 2008 and 2010 in Malawi's largest public, integrated TB/HIV clinic were included in the study to assess treatment outcomes by HIV and antiretroviral therapy status using logistic regression. RESULTS: Of 2,361 new smear-positive pulmonary TB patients, 86% had successful treatment outcome (were cured or completed treatment, 5% died, 6% were lost to follow-up, 1% failed treatment, and 2% transferred-out. Overall HIV prevalence was 56%. After adjusting for gender, age and TB registration year, treatment success was higher among HIV-negative than HIV-positive patients (adjusted odds ratio 1.49; 95% CI: 1.14-1.94. Of 1,275 HIV-infected pulmonary TB patients, 492 (38% received antiretroviral therapy during the study. Pulmonary TB patients on antiretroviral therapy were more likely to have successful treatment outcomes than those not on ART (adjusted odds ratio : 1.83; 95% CI: 1.29-2.60. CONCLUSION: HIV co-infection was associated with poor TB treatment outcomes. Despite high HIV prevalence and the integrated TB/HIV setting, only a minority of patients started antiretroviral therapy. Intensified patient education and provider training on the benefits of antiretroviral therapy could increase antiretroviral therapy uptake and improve TB treatment success among these most infectious patients.

    Background & objectives Little is known about outcomes after transfer out (TFO) and loss to follow-up (LTF) and how differential outcomes might bias mortality estimates, as analyses generally censor or exclude TFOs/LTF. Using data linked to the National Population Register (NPR), we explored mortality among patients TFO and LTF compared with patients retained and investigated how linkage impacted on mortality estimates. Methods A cohort analysis of routine data on adults with civil-identification numbers starting ART 2004–2009 in four large South African ART cohorts. The number, proportion, timing and mortality of TFOs and LTF were reported. Mortality was compared using Kaplan-Meier curves, Cox’s proportional hazards and competing risks regression. Results Before linkage, 1207 patients (6%) had died, 2624 (13%) were LTF, 1067 (5%) were TFO and 14583 (75%) were retained. Compared with retained, mortality risk was three times higher among TFOs (aHR 3.11, 95% CI 2.42–3.99) and 20 times higher among LTF patients (aHR 22.03, 95% CI 20.05–24.21). Excluding early deaths after TFO or LTF, the risk was comparable among TFOs and retained (aHR 0.75, 95% CI 0.54–1.03) and higher among LTF (aHR 2.85, 95% CI 2.43–3.33). After linkage, corrected mortality was higher than site-reported mortality. Censoring did not however lead to substantial underestimation of mortality among TFOs. Conclusions While TFO and LTF predicted mortality, the lower incidence of TFO and subsequent death compared with LTF meant that censoring TFOs did not bias mortality estimates. Future cohort analyses should explicitly consider proportions TFO/LTF and mortality event rates. PMID:24977471

    Low food availability during early growth and development can have long-term negative consequences for reproductive success. Phenotypic plasticity in adult life-history decisions may help to mitigate these potential costs, yet adult life-history responses to juvenile food conditions remain largely unexplored. I used a food-manipulation experiment with female Trinidadian guppies (Poecilia reticulata) to examine age-related changes in adult life-history responses to early food conditions, whether these responses varied across different adult food conditions, and how these responses affected overall reproductive success. Guppy females reared on low food as juveniles matured at a later age, at a smaller size, and with less energy reserves than females reared on high food as juveniles. In response to this setback, they changed their investment in growth, reproduction, and fat storage throughout the adult stage such that they were able to catch up in body size, increase their reproductive output, and restore their energy reserves to levels comparable to those of females reared on high food as juveniles. The net effect was that adult female guppies did not merely mitigate but surprisingly were able to fully compensate for the potential long-term negative effects of poor juvenile food conditions on reproductive success.

    2016-01-01

    In this update, antiretroviral therapy (ART) is recommended for all patients infected by type 1 human immunodeficiency virus (HIV-1). The objective of ART is to achieve an undetectable plasma viral load (PVL). Initial ART should comprise 3 drugs, namely, 2 nucleoside reverse transcriptase inhibitors (NRTI), and 1 drug from another family. Four of the recommended regimens, all of which have an integrase strand transfer inhibitor (INSTI) as the third drug, are considered a preferred regimen; a further 6 regimens, which are based on an INSTI, a non-nucleoside reverse transcriptase inhibitor (NNRTI), or a protease inhibitor boosted with cobicistat or ritonavir (PI/COBI, PI/r), are considered alternatives. The reasons and criteria for switching ART are presented both for patients with an undetectable PVL and for patients who experience virological failure, in which case the rescue regimen should include 3 (or at least 2) drugs that are fully active against HIV. The specific criteria for ART in special situations (acute infection, HIV-2 infection, pregnancy) and comorbid conditions (tuberculosis and other opportunistic infections, kidney disease, liver disease, and cancer) are updated.

The reasons and criteria for switching ART are presented both for patients with an undetectable PVL and for patients who experience virological failure, in which case the rescue regimen should include 3 (or at least 2) drugs that are fully active against HIV. The specific criteria for ART in special situations (acute infection, HIV-2 infection, pregnancy) and comorbid conditions (tuberculosis and other opportunistic infections, kidney disease, liver disease, and cancer) are updated.

    While substance use is one of the most consistent predictors of poor adherence to antiretroviral therapy (ART), few studies among people living with HIV (PLH) have utilized mobile phone-based assessment of these health behaviors. PLH were recruited from primary care clinics to report ART and substance use using a smartphone application (app) for 14 consecutive days. The app's feasibility as a data collection tool was evaluated quantitatively via surveys and qualitatively via in-depth interviews to assess daily report completion, compliance, and study satisfaction. Overall, 26 participants (M = 49.5 years, 76% male) completed 95.3% of time-based daily reports. Participants reported high satisfaction with the app and expressed future interest in using smartphones to report daily behaviors. High completion rates and participant acceptability suggest that smartphones are a feasible, acceptable method for collecting substance use and ART data among PLH. Potential areas of concern such as sufficient training and assistance for those with limited smartphone experience should be considered for future app-based research studies among PLH. PMID:27610243

    Full Text Available Abstract Background Health Related Quality of Life (HRQoL is an important outcome in times of Highly Active Antiretroviral Treatment (HAART. We compared the HRQoL of HIV positive patients receiving HAART with those awaiting treatment in public sector facilities in the Free State province in South Africa. Methods A stratified random sample of 371 patients receiving or awaiting HAART were interviewed and the EuroQol-profile, EuroQol-index and Visual Analogue Scale (VAS were compared. Independent associations between these outcomes and HAART, socio-demographic, clinical and health service variables were estimated using linear and ordinal logistic regression, adjusted for intra-clinic clustering of outcomes. Results Patients receiving HAART reported better HRQoL for 3 of the 5 EuroQol-dimensions, for the VAS score and for the EuroQol index in bivariable analysis. They had a higher mean EuroQol index (0.11 difference, 95% confidence interval [CI] 0.04; 0.23, and were more likely to have a higher index (odds ratio 1.9, 95% CI 1.1; 1.3, compared to those awaiting HAART, in multivariate analysis. Higher mean VAS scores were reported for patients who were receiving HAART (6.5 difference, 95% CI 1.3; 11.7, were employed (9.1, 95% CI 4.3; 13.7 or were female (4.7, 95% CI 0.79; 8.5. Conclusion HAART was associated with improved HRQoL in patients enrolled in a public sector treatment program in South Africa. Our finding that the EuroQol instrument was sensitive to HAART supports its use in future evaluation of HIV/AIDS care in South Africa. Longitudinal studies are needed to evaluate changes in individuals' HRQoL.

    Full Text Available Antiretroviral therapy (ART has transformed HIV infection into a treatable, chronic condition. However, the need to continue treatment for decades rather than years, calls for a long-term perspective of ART. Adherence to the regimen is essential for successful treatment and sustained viral control. Studies have indicated that at least 95% adherence to ART regimens is optimal. It has been demonstrated that a 10% higher level of adherence results in a 21% reduction in disease progression. The various factors affecting success of ART are social aspects like motivation to begin therapy, ability to adhere to therapy, lifestyle pattern, financial support, family support, pros and cons of starting therapy and pharmacological aspects like tolerability of the regimen, availability of the drugs. Also, the regimen′s pill burden, dosing frequency, food requirements, convenience, toxicity and drug interaction profile compared with other regimens are to be considered before starting ART. The lack of trust between clinician and patient, active drug and alcohol use, active mental illness (e.g. depression, lack of patient education and inability of patients to identify their medications, lack of reliable access to primary medical care or medication are considered to be predictors of inadequate adherence. Interventions at various levels, viz. patient level, medication level, healthcare level and community level, boost adherence and overall outcome of ART.

    Introduction With the new ‘test and treat’ policy of the WHO, it is obvious that the number of HIV-infected patients taking antiretroviral therapy (ART) will grow exponentially, with consequential increase in the burden of diabetes mellitus (DM). Our aim is to summarise existing data on the incidence of pre-diabetes and DM, and associated risk factors among HIV-infected adults. Methods and analysis This systematic review will include cohort studies reporting the incidence of pre-diabetes and/or DM, and associated risk factors among HIV-infected adults on ART, with these patients being free of any impaired glucose metabolism at study baseline. We will perform electronic searches in PubMed, Excerpta Medica Database (EMBASE), Web of Science and WHO Global Health Library, supplemented with manual searches. Articles published from 1 January 2000 to 31 July 2016, in English or French languages, and without any geographical restriction will be eligible for inclusion. 3 authors will independently screen, select studies, extract data and assess the risk of bias with discrepancies resolved by consensus. We will assess clinical heterogeneity by examining the study design and setting, criteria and cut-offs used to define pre-diabetes or DM, process of calculation of incidence and outcomes in each study. We will also assess statistical heterogeneity using the χ2 test of homogeneity and quantify it using the I2 statistic. A random effects meta-analysis will be used to estimate the overall cumulative incidence of pre-diabetes/DM and risk factors. Ethics and dissemination This systematic review will use data from published studies and does not require ethics approval. Its results are expected to help putting in place action plans and preventive measures to curb the growing burden of DM in the HIV population on ART. Findings will be published in a peer-reviewed journal and presented at scientific conferences. PROSPERO registration number CRD42016039651. PMID:27633645

    The most recent UNAIDS figures indicate that approximately 30 million people are infected with HIV worldwide, 5.8 million of whom were newly infected during 1997. At the 10th International Conference on AIDS and Sexually Transmitted Diseases in Africa, the President and Secretary of Health of France called upon developed countries to establish a Therapeutic Assistance Fund to make antiretrovirals available to people with HIV/AIDS in sub-Saharan Africa. While the annual per capita health budget in most African countries is less than US$10, triple antiretroviral therapy against AIDS in the developed world costs $12,000-14,000 per patient per year. Calculations based upon a lower per patient cost of $7000, and treating all 1.4 million African AIDS cases, would cost US$10 billion per year for drugs alone, more than 30 times the amount currently spent annually by international donors for AIDS programs in the entire developing world. Basic infrastructural requirements would have to be met were antiretrovirals made widely available, ranging from HIV screening and counseling to the provision of clean water with which to consume the required 20-30 tablets per day. High program costs will challenge long-term sustainability. Universal access to care and treatment for HIV infection and AIDS is not a reality in the developed world, let alone feasible in developing countries. Given the competing health care priorities in developing countries, the high costs of antiretroviral agents, poor infrastructure, and inability to sustain such a program, the French initiative is ill-advised and foolish public health practice.

    Background Initiating antiretroviral therapy (ART) early during tuberculosis (TB) treatment increases survival; however, implementation is suboptimal. Implementation science studies are needed to identify interventions to address this evidence-to-program gap. Objective The Start TB Patients on ART and Retain on Treatment (START) Study is a mixed-methods, cluster-randomized trial aimed at evaluating the effectiveness, cost-effectiveness, and acceptability of a combination intervention package (CIP) to improve early ART initiation, retention, and TB treatment success among TB/HIV patients in Berea District, Lesotho. Design Twelve health facilities were randomized to receive the CIP or standard of care after stratification by facility type (hospital or health center). The CIP includes nurse training and mentorship, using a clinical algorithm; transport reimbursement and health education by village health workers (VHW) for patients and treatment supporters; and adherence support using text messaging and VHW. Routine data were abstracted for all newly registered TB/HIV patients; anticipated sample size was 1,200 individuals. A measurement cohort of TB/HIV patients initiating ART was recruited; the target enrollment was 384 individuals, each to be followed for the duration of TB treatment (6–9 months). Inclusion criteria were HIV-infected; on TB treatment; initiated ART within 2 months of TB treatment initiation; age ≥18; English- or Sesotho-speaking; and capable of informed consent. The exclusion criterion was multidrug-resistant TB. Three groups of key informants were recruited from intervention clinics: early ART initiators; non/late ART initiators; and health care workers. Primary outcomes include ART initiation, retention, and TB treatment success. Secondary outcomes include time to ART initiation, adherence, change in CD4+ count, sputum smear conversion, cost-effectiveness, and acceptability. Follow-up and data abstraction are complete.

    Full Text Available Abstract Background Use of multivitamin supplements during the pre-HAART era has been found to reduce viral load, enhance immune response, and generally improve clinical outcomes among HIV-infected adults. However, immune reconstitution is incomplete and significant mortality and opportunistic infections occur in spite of HAART. There is insufficient research information on whether multivitamin supplementation may be beneficial as adjunct therapy for HIV-infected individuals taking HAART. We propose to evaluate the efficacy of a single recommended daily allowance (RDA of micronutrients (including vitamins B-complex, C, and E in slowing disease progression among HIV-infected adults receiving HAART in Uganda. Methods/Design We are using a randomized, double-blind, placebo-controlled trial study design. Eligible patients are HIV-positive adults aged at least 18 years, and are randomized to receive either a placebo; or multivitamins that include a single RDA of the following vitamins: 1.4 mg B1, 1.4 mg B2, 1.9 mg B6, 2.6 mcg B12, 18 mg niacin, 70 mg C, 10 mg E, and 0.4 mg folic acid. Participants are followed for up to 18 months with evaluations at baseline, 6, 12 and 18 months. The study is primarily powered to examine the effects on immune reconstitution, weight gain, and quality of life. In addition, we will examine the effects on other secondary outcomes including the risks of development of new or recurrent disease progression event, including all-cause mortality; ARV regimen change from first- to second-line therapy; and other adverse events as indicated by incident peripheral neuropathy, severe anemia, or diarrhea. Discussions The conduct of this trial provides an opportunity to evaluate the potential benefits of this affordable adjunct therapy (multivitamin supplementation among HIV-infected adults receiving HAART in a developing country setting.

    The objective of this study is to assess the relationship between alcohol taxation changes and drinking initiation among adolescents and young adults (collectively "youth") in Thailand (a middle-income country). Using a survey panel, this study undertook an age-period-cohort analysis using four large-scale national cross-sectional surveys of alcohol consumption performed in Thailand in 2001, 2004, 2007 and 2011 (n=87,176 Thai youth, 15-24 years of age) to test the hypothesis that changes in the inflation-adjusted alcohol taxation rates are associated with drinking initiation. Regression analyses were used to examine the association between inflation-adjusted taxation increases and the prevalence of lifetime drinkers. After adjusting for potential confounders, clear cohort and age effects were observed. Furthermore, a 10% increase of the inflation-adjusted taxation rate of the total alcohol market was significantly associated with a 4.3% reduction in the prevalence of lifetime drinking among Thai youth. In conclusion, tax rate changes in Thailand from 2001 to 2011 were associated with drinking initiation among youth. Accordingly, increases in taxation may prevent drinking initiation among youth in countries with a high prevalence of abstainers and may reduce the harms caused by alcohol.

    This paper outlines what is involved in Sure Start, one of New Labour's key social policy interventions. It is argued that there are policy continuities with older redemptive policies which focus on young children. It is also argued that Sure Start could provide a bridgehead for a more socially democratic orientation into early childhood policy.

    Full Text Available Rebecca Pavlos, Elizabeth J PhillipsInstitute for Immunology and Infectious Diseases, Murdoch University, Murdoch, Western Australia, AustraliaAbstract: Antiretroviral therapy (ART has evolved considerably over the last three decades. From the early days of monotherapy with high toxicities and pill burdens, through to larger pill burdens and more potent combination therapies, and finally, from 2005 and beyond where we now have the choice of low pill burdens and once-daily therapies. More convenient and less toxic regimens are also becoming available, even in resource-poor settings. An understanding of the individual variation in response to ART, both efficacy and toxicity, has evolved over this time. The strong association of the major histocompatibility class I allele HLA-B*5701 and abacavir hypersensitivity, and its translation and use in routine HIV clinical practice as a predictive marker with 100% negative predictive value, has been a success story and a notable example of the challenges and triumphs in bringing pharmacogenetics to the clinic. In real clinical practice, however, it is going to be the exception rather than the rule that individual biomarkers will definitively guide patient therapy. The need for individualized approaches to ART has been further increased by the importance of non-AIDS comorbidities in HIV clinical practice. In the future, the ideal utilization of the individualized approach to ART will likely consist of a combined approach using a combination of knowledge of drug, virus, and host (pharmacogenetic and pharmacoecologic [factors in the individual's environment that may be dynamic over time] information to guide the truly personalized prescription. This review will focus on our knowledge of the pharmacogenetics of the efficacy and toxicity of currently available antiretroviral agents and the current and potential utility of such information and approaches in present and future HIV clinical care.Keywords: HIV

    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

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

    Full Text Available Abstract Background For antiretroviral therapy (ART naive human immunodeficiency virus (HIV infected adults suffering from tuberculosis (TB, there is uncertainty about the optimal time to initiate highly active antiretroviral therapy (HAART after starting antituberculosis treatment (ATT, in order to minimize mortality, HIV disease progression, and adverse events. Methods In a randomized, open label trial at All India Institute of Medical Sciences, New Delhi, India, eligible HIV positive individuals with a diagnosis of TB were randomly assigned to receive HAART after 2-4 or 8-12 weeks of starting ATT, and were followed for 12 months after HAART initiation. Participants received directly observed therapy short course (DOTS for TB, and an antiretroviral regimen comprising stavudine or zidovudine, lamivudine, and efavirenz. Primary end points were death from any cause, and progression of HIV disease marked by failure of ART. Findings A total of 150 patients with HIV and TB were initiated on HAART: 88 received it after 2-4 weeks (early ART and 62 after 8-12 weeks (delayed ART of starting ATT. There was no significant difference in mortality between the groups after the introduction of HAART. However, incidence of ART failure was 31% in delayed versus 16% in early ART arm (p = 0.045. Kaplan Meier disease progression free survival at 12 months was 79% for early versus 64% for the delayed ART arm (p = 0.05. Rates of adverse events were similar. Interpretation Early initiation of HAART for patients with HIV and TB significantly decreases incidence of HIV disease progression and has good tolerability. Trial registration CTRI/2011/12/002260

  10. The Place of protease inhibitors in antiretroviral treatment

    2009-10-01

    Full Text Available With the introduction of highly active antiretroviral therapy, a number of drugs have been developed. The best choice concerning which antiretroviral analogs to start is always under discussion, especially in the choice between non-nucleoside reverse transcriptase inhibitors-based therapies and ritonavir-boosted protease inhibitors. Both are proven to control viral replication and lead to immunological gain. The choice between a non-nucleoside analog reverse transcriptase inhibitor and a protease inhibitor as a third antiretroviral drug in the therapy should consider factors related to the individual, as well as the inclusion of the best therapy in the patient's daily activities and potential adherence. The protease inhibitor-based therapies showed similar efficacy among the various inhibitors with characteristics concerning the adverse events from each medicine. For the treatment of protease-resistant patients, darunavir and tipranavir showed good efficacy with higher genetic barrier to resistance.

    Background In resource-limited countries, estimating CD4-specific incidence rates of mortality and morbidity among patients receiving antiretroviral therapy (ART) may help assess the effectiveness of care and treatment programmes, identify program weaknesses and inform decisions. Methods We pooled data from 13 research cohorts in five sub-Saharan African (Benin, Burkina Faso, Cameroon, Cote d'Ivoire and Senegal) and two Asian (Cambodia and Laos) countries. HIV-infected adults (≥18 years) who received ART in 1998-2008 and had at least one CD4 count available were eligible. Changes in CD4 counts over time were estimated by a linear mixed regression. CD4-specific incidence rates were estimated as the number of first events occurring in a given CD4 stratum divided by the time spent within the stratum. Results Overall 3,917 adults (62% women) on ART were followed-up during 10,154 person-years. In the ≤50, 51-100, 101-200, 201-350, 351-500, 501-650 and >650/mm3 CD4 cells strata, death rates were: 20.6, 11.8, 6.7, 3.3, 1.8, 0.9 and 0.3 per 100 person-years; AIDS rates were: 50.5, 32.9, 11.5, 4.8, 2.8, 2.2 and 2.2 per 100 person-years; and loss to follow-up rates were: 4.9, 6.1, 3.5, 3.1, 2.9, 1.7 and 1.2 per 100 person-years, respectively. Mortality and morbidity were higher during the first year following ART initiation. Conclusion In these resource-limited settings, death and AIDS rates remained substantial after ART initiation, even in individuals with high CD4 cell counts. Ensuring earlier ART initiation and optimizing case finding and treatment for AIDS-defining diseases should be seen as priorities. PMID:23274931

Methods HIV-infected adults (≥15 years who enrolled in HIV care at Haydom Lutheran Hospital in northern Tanzania were included in the study. The effect of ART (zidovudine/stavudine + lamivudine + efavirenz/nevirapine on HIV-associated anemia was studied in a subset of patients who were anemic at the time they started ART and had a follow-up hemoglobin measurement 12 months later. Pregnant women were excluded from the study, as were women who had given birth within the past 6 weeks. Anemia was defined as hemoglobin Results At enrollment, mean hemoglobin was 10.3 g/dL, and 649 of 838 patients (77.4% were anemic. Of the anemic patients, 254 (39.1% had microcytosis and hypochromia. Among 102 patients who were anemic at ART initiation and had a follow-up hemoglobin measurement after 12 months, the mean hemoglobin increased by 2.5 g/dL (P Conclusions Most patients had anemia at enrollment, of whom nearly 40% had microcytosis and hypochromia suggestive of iron deficiency. The mean hemoglobin increased significantly in patients who received ART, but one third were still anemic 12 months after ART initiation indicating that additional interventions to treat HIV-associated anemia in rural Africa might be warranted, particularly in patients with microcytosis and those treated with zidovudine.

    Most researches on adults' lifelong learning competency consider it from a national-level policy tool perspective, and ignore the exploration of its theoretical basis from a micro perspective. Thus, the logical starting point of research has never been found, nor has a panoramic view of the cultivation of lifelong learning competency. Among adults' many learning abilities, the lifelong learning competency is the most critical one, the building of which requires a re-examination of the nature of adult learning, its internal mechanisms and their relationship. The individual cognitive perspective, which is the sole focus of traditional approaches, should be combined with practice-oriented perspective. Therefore, to study the essence of the internal mechanism of the formation of adults' lifelong learning competency, we need to explore the relationship of the three learning mechanism of cognition, regulation and interaction, as well as the relationship among the three mechanisms and the learning process.Thereby, the logical basis for adults' lifelong learning competency system could be founded and the qualitative items can be divided. On this basis, further quantitative items can be pursued and a common theoretical basis for the key items of adults' lifelong learning competency can be explored.%纵观学界对成人终身学习能力的研究,多从国家层面的一种政策性工具角度探讨,忽视从微观层面深挖其架构的理论基础并据此演绎出能力项的研究,没有真正找到研究的逻辑起点,导致对终身学习能力培养缺少全景式认识。成人终身学习能力是成人的众多学习能力中最关键、最核心的能力。这一能力的建构研究需要从成人的学习实质、内在机制及其相互关系中重新审视,要避免仅从个体认知视角研究的传统立场,应秉承个体认知视角与实践取向视角相结合的研究方式。因此,研究成人终身学习能力形成的内在机制

    Full Text Available HIV-2 is endemic in West Africa. There is a lack of evidence-based guidelines on the diagnosis, management and antiretroviral therapy (ART for HIV-2 or HIV-1/HIV-2 dual infections. Because of these issues, we designed a West African collaborative cohort for HIV-2 infection within the framework of the International epidemiological Databases to Evaluate AIDS (IeDEA.We collected data on all HIV-2 and HIV-1/HIV-2 dually seropositive patients (both ARV-naive and starting ART and followed-up in clinical centres in the IeDEA-WA network including a total of 13 clinics in five countries: Benin, Burkina-Faso Côte d'Ivoire, Mali, and Senegal, in the West Africa region.Data was merged for 1,754 patients (56% female, including 1,021 HIV-2 infected patients (551 on ART and 733 dually seropositive for both HIV-1 and HIV 2 (463 on ART. At ART initiation, the median age of HIV-2 patients was 45.3 years, IQR: (38.3-51.7 and 42.4 years, IQR (37.0-47.3 for dually seropositive patients (p = 0.048. Overall, 16.7% of HIV-2 patients on ART had an advanced clinical stage (WHO IV or CDC-C. The median CD4 count at the ART initiation is 166 cells/mm(3, IQR (83-247 among HIV-2 infected patients and 146 cells/mm(3, IQR (55-249 among dually seropositive patients. Overall, in ART-treated patients, the CD4 count increased 126 cells/mm(3 after 24 months on ART for HIV-2 patients and 169 cells/mm(3 for dually seropositive patients. Of 551 HIV-2 patients on ART, 5.8% died and 10.2% were lost to follow-up during the median time on ART of 2.4 years, IQR (0.7-4.3.This large multi-country study of HIV-2 and HIV-1/HIV-2 dual infection in West Africa suggests that routine clinical care is less than optimal and that management and treatment of HIV-2 could be further informed by ongoing studies and randomized clinical trials in this population.

    This level sets the stage for the design philosophy called “Triadic Game Design” (TGD). This design philosophy can be summarized with the following sentence: it takes two to tango, but it takes three to design a meaningful game or a game with a purpose. Before the philosophy is further explained, this level will first delve into what is meant by a meaningful game or a game with a purpose. Many terms and definitions have seen the light and in this book I will specifically orient at digital games that aim to have an effect beyond the context of the game itself. Subsequently, a historical overview is given of the usage of games with a serious purpose which starts from the moment we human beings started to walk on our feet till our contemporary society. It turns out that we have been using games for all kinds of non-entertainment purposes for already quite a long time. With this introductory material in the back of our minds, I will explain the concept of TGD by means of a puzzle. After that, the protagonist of this book, the game Levee Patroller, is introduced. Based on the development of this game, the idea of TGD, which stresses to balance three different worlds, the worlds of Reality, Meaning, and Play, came into being. Interested? Then I suggest to quickly “press start!”

  18. A lot of mental illness starts in adolescence. Therefore should we shift some of the spending from adult to adolescent mental health services?

    Neal, David

    2015-09-01

    In May 2015 the UK elected a new government. In election campaigns, health is one of the most important areas of debate and over the preceding 12 months, the state of child and adolescent mental health services (CAMHS) had held a particularly high profile in the media and in political debate. Many had suggested that the rate of mental illness starting in adolescence is increasing and that service provision is not of sufficient quality or scale to meet this need. A brief review of the sources for these statistics reveals that whilst this may be true, there is a dearth of accurate and up to date data on the scale of the need for CAMHS or the extent to which it is being met. Nonetheless, members of all parties claimed to support improvements in mental health service provision for children and adolescents through increases in funding. A key question for policy makers has therefore become, from where any additional funding might be derived. One suggestion has been that funding be transferred from spending on adult mental health services. The exact practical nature of such a policy is yet to be explored in detail by government or stakeholders. The primary purpose of the present discussion is therefore to consider the possible ethical implications of such a policy in principle. The discussion forms part of a wider and evolving political and professional discourse on society's and government's attitude towards mental illness, towards the balance of individual and societal needs and towards the balance between preventative and supportive interventions to improve health.

    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

    Background While there has been a rapid global scale-up of antiretroviral therapy programs over the past decade, there are limited data on long-term outcomes from large cohorts in resource-constrained settings. Our objective in this evaluation was to measure multiple outcomes during first-line antiretroviral therapy in a large treatment program in Nigeria. Methods We conducted a retrospective multi-site program evaluation of adult patients (age ≥15 years) initiating antiretroviral therapy between June 2004 and February 2012 in Nigeria. The baseline characteristics of patients were described and longitudinal analyses using primary endpoints of immunologic recovery, virologic rebound, treatment failure and long-term adherence patterns were conducted. Results Of 70,002 patients, 65.2% were female and median age was 35 (IQR: 29–41) years; 54.7% were started on a zidovudine-containing and 40% on a tenofovir-containing first-line regimen. Median CD4+ cell counts for the cohort started at 149 cells/mm3 (IQR: 78–220) and increased over duration of ART. Of the 70,002 patients, 1.8% were reported as having died, 30.1% were lost to follow-up, and 0.1% withdrew from treatment. Overall, of those patients retained and with viral load data, 85.4% achieved viral suppression, with 69.3% achieving suppression by month 6. Of 30,792 patients evaluated for virologic failure, 24.4% met criteria for failure and of 45,130 evaluated for immunologic failure, 34.0% met criteria for immunologic failure, with immunologic criteria poorly predicting virologic failure. In adjusted analyses, older age, ART regimen, lower CD4+ cell count, higher viral load, and inadequate adherence were all predictors of virologic failure. Predictors of immunologic failure differed slightly, with age no longer predictive, but female sex as protective; additionally, higher baseline CD4+ cell count was also predictive of failure. Evaluation of long-term adherence patterns revealed that the majority of patients

    Full Text Available BACKGROUND: Limited information exists on long-term prognosis of patients with sustained virologic response to antiretroviral therapy. We aimed to assess predictors of unfavorable clinical outcome in patients who maintain viral suppression with HAART. METHODS: Using data collected from ten clinic-based cohorts in Spain, we selected all antiretroviral-naive adults who initiated HAART and maintained plasma HIV-1 RNA levels <500 copies/mL throughout follow-up. Factors associated with disease progression were determined by Cox proportional-hazards models. RESULTS: Of 2,613 patients who started HAART, 757 fulfilled the inclusion criteria. 61% of them initiated a protease inhibitor-based HAART regimen, 29.7% a nonnucleoside reverse-transcriptase inhibitor-based regimen, and 7.8% a triple-nucleoside regimen. During 2,556 person-years of follow-up, 22 (2.9% patients died (mortality rate 0.86 per 100 person-years, and 40 (5.3% died or developed a new AIDS-defining event. The most common causes of death were neoplasias and liver failure. Mortality was independently associated with a CD4-T cell response <50 cells/L after 12 months of HAART (adjusted hazard ratio [AHR], 4.26 [95% confidence interval {CI}, 1.68-10.83]; P = .002, and age at initiation of HAART (AHR, 1.06 per year; 95% CI, 1.02-1.09; P = .001. Initial antiretroviral regimen chosen was not associated with different risk of clinical progression. CONCLUSIONS: Patients with sustained virologic response on HAART have a low mortality rate over time. Long-term outcome of these patients is driven by immunologic response at the end of the first year of therapy and age at the time of HAART initiation, but not by the initial antiretroviral regimen selected.

    Full Text Available We report 2 cases illustrating that it is too simplistic to link nevirapine (NVP toxicity exclusively to individuals with immune preservation. Not enough is known about the mechanism of hepatotoxicity or cutaneous eruption to predict these events. This type of hypersensitivity reaction occurs rarely among HIV-exposed infants taking NVP prophylaxis or antiretroviral therapy (ART-experienced adults with complete plasma viral load suppression. Conversely, HIV-uninfected adults and ART-naive pregnant women appear to be disproportionately affected by the adverse effects of NVP.

    Full Text Available The relationship between characteristics of HIV antiretroviral regimens and treatment adherence was studied in adolescent and adult patients who underwent antiretroviral therapy from January 1998 to September 2000, at the Service for Specialized Assistance in Pelotas. The patients were interviewed on two occasions, and the use of antiretrovirals during the previous 48 hours was investigated by a self-report. Adherence was defined as use of 95% or more of the prescribed medication. Social-demographic variables were collected through direct questionnaires. The antiretroviral regimen and clinical data were copied from the patients' records. Associations between the independent variables and adherence were analyzed by means of logistic regression. The multivariate analysis included characteristics of the antiretroviral regimens, social-demographic variables, as well as perception of negative effects, negative physiological states, and adverse effects of the treatment. Among the 224 selected patients, 194 participated in our study. Their ages varied from 17 to 67 years; most patients were men, with few years of schooling and a low family income. Only 49% adhered to the treatment. Adherence to treatment regimens was reduced when more daily doses were indicated: three to four doses (odds ratio of adherence to treatment (OR=0.47, 95% confidence interval (CI 0.22-1.01 and five to six (OR=0.24, 95% CI 0.09-0.62; two or more doses taken in a fasting state (OR=0.59, 95% CI 0.11-0.68, and for patients who reported adverse effects to the treatment (OR=0.39, 95% CI 0.19-0.77. Most of the regimens with more than two daily doses of medication included at least one dose apart from mealtimes. The results suggest that, if possible, regimens with a reduced number of doses should be chosen, with no compulsory fasting, and with few adverse effects. Strategies to minimize these effects should be discussed with the patients.

    In Africa, antiretroviral therapy (ART) is delivered with limited laboratory monitoring, often none. In 2003-2004, investigators in the Development of Antiretroviral Therapy in Africa (DART) Trial randomized persons initiating ART in Uganda and Zimbabwe to either laboratory and clinical monitoring (LCM) or clinically driven monitoring (CDM). CD4 cell counts were measured every 12 weeks in both groups but were only returned to treating clinicians for management in the LCM group. Follow-up continued through 2008. In observational analyses, dynamic marginal structural models on pooled randomized groups were used to estimate survival under different monitoring-frequency and clinical/immunological switching strategies. Assumptions included no direct effect of randomized group on mortality or confounders and no unmeasured confounders which influenced treatment switch and mortality or treatment switch and time-dependent covariates. After 48 weeks of first-line ART, 2,946 individuals contributed 11,351 person-years of follow-up, 625 switches, and 179 deaths. The estimated survival probability after a further 240 weeks for post-48-week switch at the first CD4 cell count less than 100 cells/mm(3) or non-Candida World Health Organization stage 4 event (with CD4 count findings support a benefit from identifying patients immunologically failing first-line ART at 48 weeks.

    China has recognized the threat of HIV to its population and responded with a national antiretroviral treatment (ART)program. However, high ART failure rates and the spread of resistance within populations are important realities to consider when developing and managing ART programs in China and worldwide. Concepts which will define treatment success and local and national programmatic goals are 1) access to ART, 2) durability of ART at the patient level, 3)scalability of treatment modalities, and the 4) sustainability of the program at the community or national level. In the face of limited resources, China must also consider when to start ARV therapy, which agents to use, when to switch them, and how to treat highly experienced patients with drug resistance. The optimal ARV regimen to start with is changing frequently with the introduction of new agents and the presentation of new data. Currently, a regimen including tenofovir, emtricitabine or lamivudine and a nonnucleoside reverse transcriptase inhibitor appears to have optimal characteristics to treat HIV/AIDS in China. However, critical to all of these choices is the evaluation of programs implemented to insure wide scale success. China has wisely begun this process of evaluating the performance of local programs through systematic monitoring and evaluation of treatment outcomes. This will allow regimens and programs that work to be expanded, and programs with high failure rates to be eliminated. In the end,evidence based data supporting treatment strategies will allow China to successfully confront its AIDS epidemic early and prevent its tragic consequences

    Coadministration of antituberculosis and antiretroviral therapy is often inevitable in high-burden countries where tuberculosis (TB) is the most common opportunistic infection associated with HIV/AIDS. Concurrent use of rifampicin and many antiretroviral drugs is complicated by pharmacokinetic drug-drug interactions. Rifampicin is a very potent enzyme inducer, which can result in subtherapeutic antiretroviral drug concentrations. In addition, TB drugs and antiretroviral drugs have additive (pharmacodynamic) interactions as reflected in overlapping adverse effect profiles. This review provides an overview of the pharmacological interactions between rifampicin-based TB treatment and antiretroviral drugs in adults living in resource-limited settings. Major progress has been made to evaluate the interactions between TB drugs and antiretroviral therapy; however, burning questions remain concerning nevirapine and efavirenz effectiveness during rifampicin-based TB treatment, treatment options for TB-HIV-coinfected patients with nonnucleoside reverse transcriptase inhibitor resistance or intolerance, and exact treatment or dosing schedules for vulnerable patients including children and pregnant women. The current research priorities can be addressed by maximizing the use of already existing data, creating new data by conducting clinical trials and prospective observational studies and to engage a lobby to make currently unavailable drugs available to those most in need.

    Full Text Available The Acquired Immune Deficiency Syndrome epidemic, caused by the Human Immunodeficiency Virus, is a global crisis which threatens development gains, economies, and societies. Within sub-Saharan Africa, where the epidemic began the earliest and the HIV prevalence is the highest, African countries have death rates not seen before. In South Africa the epidemic has a devastating impact which creates profound suffering on individuals and their families, and the impact on the socio-economic level is of great concern. The eradication of HIV/AIDS represents one of humanity’s greatest challenges, which requires co-operation and comprehensive collaboration between many different role players. In this endeavour clinical information plays a major role. To combat the effect of the disease, the Free State Department of Health started with the provisioning of antiretroviral therapy in the public health sector. The objective of this paper was to address the challenges they faced in order to develop and implement an information system to manage the rollout of antiretroviral treatment effectively. They started with a paper-based system to collect vital information. It was followed by a palm computer project that was initiated to electronically capture the data collected by the paper-based system. This system was then replaced by a comprehensive Hospital and Clinic Information System which was acquired and customised for the antiretroviral data collection process. Research partners developed a standalone antiretroviral data warehouse for collecting information associated with the monitoring and evaluation of the Free State antiretroviral and HIV/ AIDS treatment programme. The data warehouse successfully produced several management information reports to the antiretroviral management team. A need was identified to design a comprehensive antiretroviral data warehouse that will integrate data from several operational sources which are all associated with HIV/AIDS.

    Full Text Available Abstract Background KwaZulu-Natal is the South African province worst affected by HIV and the focus of early modeling studies investigating strategies of antiretroviral treatment (ART delivery. The reality of antiretroviral roll-out through primary care has differed from that anticipated and real world data are needed to inform the planning of further scaling up of services. We investigated the factors associated with uptake of antiretroviral treatment through a primary healthcare system in rural South Africa. Methods Detailed demographic, HIV surveillance and geographic information system (GIS data were used to estimate the proportion of HIV positive adults accessing antiretroviral treatment within northern KwaZulu-Natal, South Africa in the period from initiation of antiretroviral roll-out until the end of 2008. Demographic, spatial and socioeconomic factors influencing the likelihood of individuals accessing antiretroviral treatment were explored using multivariable analysis. Results Mean uptake of ART among HIV positive resident adults was 21.0% (95%CI 20.1-21.9. Uptake among HIV positive men (19.2% was slightly lower than women (21.8%, P = 0.011. An individual's likelihood of accessing ART was not associated with level of education, household assets or urban/rural locale. ART uptake was strongly negatively associated with distance from the nearest primary healthcare facility (aOR = 0.728 per square-root transformed km, 95%CI 0.658-0.963, P = 0.002. Conclusions Despite concerns about the equitable nature of antiretroviral treatment rollout, we find very few differences in ART uptake across a range of socio-demographic variables in a rural South African population.

    As the severity of the HIV epidemic in China grew, National Free Antiretroviral Treatment (ART) Program was announced since 2003. Even though there still were many difficulties, China had obtained great achievements in fighting against HIV.Over 52 000 adult patients had received first-line HAART thus far and the mortality of AIDS in China decreased significantly. This paper presents an overview of the HIV/AIDS epidemic in China; the status of national free ART program,the difficulties suffered and the achievements made since the initiation of program and the challenges ahead for continued progress for China. This paper also provides suggestions to overcome these challenges.

    Established by the Federal Ministry of Labour and Social Affairs (BMAS) in October 2007, the Scientific Expert Group RehaFutur had been commissioned to elaborate cornerstones for the medium- and long-term development of vocational rehabilitation of adults with disabilities (re-integration). Initial questions inter alia were as follows: Which function should vocational rehabilitation have in a service- and knowledge-oriented working world that will increasingly be affected by demographic change? How can disabled persons' right to occupational participation by way of vocational rehabilitation, a right stipulated both under the German constitution and in German law, be realized as needed also in the future? Various fields of action have been derived on the basis, for one, of an investigation of the factors, social law, social and education policy as well as European, influencing vocational rehabilitation and, for the other, of an evaluation of current labour market and demographic developments. Dealt with in the fields of action outlined are the aspects: equitable opportunities of access, developmental and needs orientation, closeness to the real occupational and working world, as well as the role of self-determination and self-responsibility. The fields of action are to be understood as framework concept for shaping a cross-actor innovation process. Sustainable vocational rehabilitation is characterized in particular by the fact that it is specifically targeted at promoting disabled persons' self-determination and self-responsibility actively using these in the process and that it strengthens an independent lifestyle, ensures social participation by inclusive structures; also, it facilitates continued participation in working life by ongoing education involving holistic development of professional and personal competencies oriented towards the individual's resources and potentials, safeguarding it by systematic networking with companies.

    2016-09-01

    The Joint United Nations Programme on HIV/AIDS (UNAIDS) has set the global goal of ending the AIDS world epidemic by 2030. In order to end this epidemic they have established a 90-90-90 goal to be achieved by 2020, which may be problematic, especially in low- and middle-income countries. This goal includes 90% of individuals with HIV globally being diagnosed, on treatment, and virologically suppressed. Based on global estimates from 2014-2015, approximately 36.9 million individuals are living with HIV. Of those, 53% have been diagnosed with HIV, 41% are on antiretroviral therapy (ART), and 32% have viral suppression with <1000 copies/ml. Comprehensive approaches are needed to improve the number of people living with HIV (PLWH) who are diagnosed, linked, and engaged in care. Once PLWH are retained in care, treatment is key to both HIV prevention and transmission. The development and advancement of new ART is necessary to assist in reaching these goals by improving safety profiles, decreasing pill burden, improving quality of life and life expectancy, and creating new mechanisms to overcome resistance. The focus of this review is to highlight and review data for antiretroviral agents recently added to the market as well as discuss agents in various stages of development (new formulations and mechanisms of action).

  4. World Health Organization guidelines should not change the CD4 count threshold for antiretroviral therapy initiation

    Directory of Open Access Journals (Sweden)

    Nathan Geffen

    2013-03-01

    Full Text Available The World Health Organization (WHO currently recommends that HIV-positive adults start antiretroviral therapy (ART at CD4 counts <350 cells/μl. Several countries have changed their guidelines to recommend ART irrespective of CD4 count or at a threshold of 500 CD4 cells/μl. Consequently, WHO is currently revising its treatment guidelines and considering recommending ART initiation at CD4 counts <500 cells/μl. Such decisions are critically important, as WHO guidelines inform healthcare policies in developing countries and are used by activists in their advocacy work. Changing the CD4 initiation point from 350 to 500 cells/μl would, however, be premature and have profound cost implications on Global Fund, President’s Emergency Plan for AIDS Relief (PEPFAR and developing country health budgets. We should be willing to campaign for such a change in guidelines despite cost implications, if supported by evidence. However, the evidence remains outstanding. S Afr J HIV Med 2013;14(1:6-7.

    Full Text Available BACKGROUND: Antiretroviral treatment (ART has been introduced in Ethiopia a decade ago and continues to be scaled up. However, there is dearth of literature on the impact of ART on changes in CD4 lymphocyte count and weight among patients on treatment. OBJECTIVE: To determine the predictors of change in CD4 lymphocyte count and weight among HIV/AIDS infected patients taking antiretroviral treatment in eastern Ethiopia. METHODS: A retrospective cohort study was conducted among HIV/AIDS patients taking ART from 2005 to 2010. A sample of 1540 HIV infected adult patients who started antiretroviral therapy in hospitals located in eastern Ethiopia were included in the study. The primary outcomes of interest were changes in CD4 count and weight. Descriptive statistics and multivariable regression analyses were performed to examine the outcomes among the cohort. RESULTS: Both the median CD4 lymphocyte counts and weight showed improvements in the follow up periods. The multivariate analysis shows that the duration of ART was an important predictor of improvements in CD4 lymphocyte count (beta 7.91; 95% CI 7.48-8.34; p 0.000 and weight (beta 0.15; 95% CI 0.13-0.18; p 0.000. Advanced WHO clinical stage, lower baseline CD4 cell count, and baseline hemoglobin levels were factors associated with decline in weight. Actively working patients had higher CD4 lymphocyte count and weight compared to those that were ambulatory (p<0.05. CONCLUSION: We detected a substantial increment in weight and CD4 lymphocyte count among the patients who were taking ART in eastern Ethiopia. Patients who are of older age, with low initial CD4 lymphocyte count, late stage of the WHO clinical stages and lower hemoglobin level may need special attention. The reasons for the improved findings on CD4 count and weight throughout the five years of follow up merit further investigation.

    Objective: assess the adherence levels to antiretroviral therapy in people coinfected with HIV/tuberculosis and correlate these levels with the sociodemographic and clinical variables of the study population. Method: cross-sectional study involving 74 male and female adults coinfected with HIV/tuberculosis. For the data collection, a sociodemographic and clinical assessment form and the Antiretroviral Treatment Adherence Assessment Questionnaire were used. For the data analysis, the software STATA version 11 was used, through descriptive statistics, Fisher's chi-square exact test and the probability test. Results: men were predominant (79.7%), between 30 and 39 years of age (35.1%), low income (75.7%) and pulmonary tuberculosis (71.6%). Adherence to antiretroviral therapy was inappropriate in 78.1% of the men; 61.0% of single people; 47.0% unemployed and 76.5% among people gaining less than one minimum wage. A significant difference was observed between compliance and length of use of antiretrovirals (p=0.018), sexual orientation (p=0.024) and number of children (p=0.029). Conclusion: the coinfected patients presented inappropriate adherence to the antiretrovirals, a fact that negatively affects the health conditions of the people living with HIV/tuberculosis coinfection. A statistically significant correlation was found between the levels of adherence and some sociodemographic and clinical characteristics. PMID:27192416

    Full Text Available 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.

    Full Text Available The impact of HIV-1 subtype on resistance mutation selection and on virologic response to fosamprenavir in combination with once-daily (QD versus twice-daily (BID dosing of ritonavir was examined in a prospective, open label, randomized study in antiretroviral-naïve, HIV-1 infected subjects. We studied APV109141 compared QD fosamprenavir/ritonavir (1400mg/100mg to BID fosamprenavir/ritonavir (700mg/100mg, administered in combination with a QD fixed-dose abacavir/lamivudine (600 mg/300 mg combination tablet through 48 weeks in ART-naïve subjects. HIV genotypes were obtained from all subjects at screen. Subjects with virologic failure (VF were also genotyped at baseline and VF. HIV subtypes observed in the ITT (n=214 population were A or AE or AG circulating recombinant forms (CRFs 19%; B 62%; BF or BG CRFs 2%; C or CPX CRFs 7%; D 2%; F1 7%; G <1%. By TLOVR (ITT-exposed, 86/106 (81% of subjects on QD study arm and 87/106 (82% in the BID arm achieved plasma HIV-RNA<400 copies/mL at Week 48. Three subjects met VF criteria, 2 receiving QD fosamprenavir/ritonavir; 1 receiving BID fosamprenavir/ritonavir; (HIV subtype B, F1 A1, respectively. Baseline drug resistance was detected in 2/3 VFs: Subject 1-RT: K103K/N, T215C; major PI: V82A, L90M; and Subject 2-RT: M41L, L74V. Only virus from one subject with VF selected for any treatment-emergent mutation (Subject 1; M184V. Post-VF, Subject 3 (subtypeA1 suppressed HIV-RNA >400 copies/mL through 48 weeks. Subtype appeared to have no preferential impact on virologic response or selection for specific resistance mutations in subjects receiving fosamprenavir/ritonavir. Virologic failure rate was rare (3 subjects; each from different subtypes. At VF, virus from only one subject selected any HIV NRTI mutation (M184V; none selected major protease mutations.

    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

    Despite effective viral suppression through combined antiretroviral therapy (cART), approximately half of HIV-positive individuals have HIV-associated neurocognitive disorders (HAND). Studies of antiretroviral-treated patients have revealed persistent white matter abnormalities including diffuse myelin pallor, diminished white matter tracts, and decreased myelin protein mRNAs. Loss of myelin can contribute to neurocognitive dysfunction because the myelin membrane generated by oligodendrocytes is essential for rapid signal transduction and axonal maintenance. We hypothesized that myelin changes in HAND are partly due to effects of antiretroviral drugs on oligodendrocyte survival and/or maturation. We showed that primary mouse oligodendrocyte precursor cell cultures treated with therapeutic concentrations of HIV protease inhibitors ritonavir or lopinavir displayed dose-dependent decreases in oligodendrocyte maturation; however, this effect was rapidly reversed after drug removal. Conversely, nucleoside reverse transcriptase inhibitor zidovudine had no effect. Furthermore, in vivo ritonavir administration to adult mice reduced frontal cortex myelin protein levels. Finally, prefrontal cortex tissue from HIV-positive individuals with HAND on cART showed a significant decrease in myelin basic protein compared with untreated HIV-positive individuals with HAND or HIV-negative controls. These findings demonstrate that antiretrovirals can impact myelin integrity and have implications for myelination in juvenile HIV patients and myelin maintenance in adults on lifelong therapy.

    Objective To investigate the situation of drug resistance among HIV-infected patients receiving long term first-line combination antiretroviral treatment (cART) and to assess the interrelated risk factors. Methods A prospective cohort study was established in 8 provinces in China since 2007. Baseline information was collected in a cross-sectional survey through multi-stage random sampling. Totall of 688 HIV-infected patients who had received first-line cART and achieved virologic suppression in 2009 were enrolled into the cohort. HIV-infected patients with viral load higher than 1000 copies/ml in 2010 were detected by ViroSeqM HIV-1 genotyping system. Life table analysis was applied to calculate the incidence of drug resistance. A sensitivity analysis was applied to evaluate the effect of second-line regimens. Based on the bivariable results, the risk factors were included into the Multivariable Logistic Regression model. Results Total of 688 HIV-infected patients receiving cART and achieving virologic suppression were eligible to this study. Among those cases, 10 cases died and 8 cases switched to second-line regimens after 12 months of follow-up. There were 29 cases with a viral load higher than 1000 copies/ml among whom, 22 patients were resistant to at least one antiretroviral drug based on genotypic assay. The incidence among drug resistance was (3.4-4.6)/100 person-years. All 22 patients were resistant to non-nucleoside reverse transcriptase inhibitor (NNRT1) and 16 patients were resistant to nucleoside reverse transcriptase inhibitor (NRTIs). No case was resistant to protease inhibitor (PI) or the combination of 3TC and TDF. Compared with patients who received cART in county level clinics or above and treated successfully, those who received cART in the village level clinic (95%CI: 2.1-19.6) and experienced virologic treatment failure (95%CI: 2.2-13.0) were most likely to occur drug resistance. Conclusions The incidence of drug resistance remained low among

    Full Text Available OBJECTIVES: In developing nations, the use of operational parameters (OPs in the prediction of clinical care represents a missed opportunity to enhance the care process. We modeled the impact of multiple measurements of antiretroviral treatment (ART adherence on antiretroviral treatment outcomes in Peru. DESIGN AND METHODS: Retrospective cohort study including ART naïve, non-pregnant, adults initiating therapy at Hospital Nacional Cayetano Heredia, Lima-Peru (2006-2010. Three OPs were defined: 1 Medication possession ratio (MPR: days with antiretrovirals dispensed/days on first-line therapy; 2 Laboratory monitory constancy (LMC: proportion of 6 months intervals with ≥1 viral load or CD4 reported; 3 Clinic visit constancy (CVC: proportion of 6 months intervals with ≥1 clinic visit. Three multi-variable Cox proportional hazard (PH models (one per OP were fit for (1 time of first-line ART persistence and (2 time to second-line virologic failure. All models were adjusted for socio-demographic, clinical and laboratory variables. RESULTS: 856 patients were included in first-line persistence analyses, median age was 35.6 years [29.4-42.9] and most were male (624; 73%. In multivariable PH models, MPR (per 10% increase HR=0.66; 95%CI=0.61-0.71 and LMC (per 10% increase 0.83; 0.71-0.96 were associated with prolonged time on first-line therapies. Among 79 individuals included in time to second-line virologic failure analyses, MPR was the only OP independently associated with prolonged time to second-line virologic failure (per 10% increase 0.88; 0.77-0.99. CONCLUSIONS: The capture and utilization of program level parameters such as MPR can provide valuable insight into patient-level treatment outcomes.

    Background Retention in care and adherence to antiretroviral therapy (ART) among people living with human immunodeficiency virus (PLHIV) is a critical challenge in many African countries including Burkina Faso. Delivering text messaging (short message service, SMS) interventions through mobile phones may help facilitate health service delivery and improve patient health. Despite this potential, no evaluations have been delivered for national scale settings to demonstrate the impact of mobile health (mHealth) for PLHIV. Objectives This study aims to test the impact of SMS text messaging reminders for PLHIV in Burkina Faso, who are under ART. The evaluation identifies whether patients who receive SMS text messages are more likely to (1) retain in care (measured as a dichotomous variable), (2) adhere to antiretroviral regimens (measured as the number of doses missed in the past 7 days), and (3) experience slower disease progression (measured with T-lymphocytes cells). The second objective is to assess its effects on the frequency of health center visits, physical and psychosocial health, nutrition and whether the type of message (text vs image) and frequency (weekly vs semiweekly) have differential impacts including the possibility of message fatigue over time. Methods This 24-month, wide-scale intervention implements a randomized controlled trial (RCT) to evaluate the impact of four variants of a mHealth intervention versus a control group. Our sample comprises adult patients (>15 years of age) undergoing antiretroviral therapy with access to mobile phone services. Multivariate regression analysis will be used to analyze the effect of the intervention on the study population. Data collection is done at baseline and three follow-up waves 6, 12, and 24 months after the intervention starts. Results The targeted 3800 patients were recruited between February 2015 and May 2015. But political uncertainty delayed the launch of the intervention until October 2015. Data

    Adulthood starts after youth and is characterized by the completion of growth and the achievement of organic and psychological maturity. Obesity and other preventable diseases related to lifestyle are common at this age.

    2016-01-01

    Non-antiretroviral microbicide candidates were previously explored as a female-controlled method of preventing sexual transmission of HIV. These products contained non-HIV specific active compounds that were ultimately found to disrupt the vaginal epithelium, cause increased immune activation in the female genital tract, disturb vaginal flora, and/or cause other irritation that precluded their use as vaginal microbicides. Due to the failure of these first-generation candidates, there was a shift in focus to developing HIV pre-exposure prophylaxis and microbicides containing small-molecule antiretrovirals. Even with the limited success of the antiretroviral-based microbicides in clinical evaluations and no commercially available products, there has been significant progress in microbicide research. The lessons learned from previous trials have given rise to more rigorous preclinical evaluation that aims to be better at predicting microbicide efficacy and safety and to novel formulation and delivery technologies. These advances have resulted in renewed interest in developing non-antiretroviral-based microbicides, such as broadly neutralizing antibodies (for example, VRC01) and anti-viral proteins (for example, Griffithsin), as options for persons not wanting to use antiretroviral drugs, and for their potential to prevent multiple sexually transmitted infections.

    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 Polypharmacy increased the risk for non-continuous ART (36.8% vs. 30.0%; p 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

    While the overall percentage of unused antiretroviral medicines returned to the hospital pharmacy is low, their cost is quite high. Adverse events, treatment failure, pharmacokinetic interactions, pregnancy, or treatment simplification are common reasons for unplanned treatment changes. Socially inefficient antiretroviral packages prevent the reuse of drugs returned to the hospital pharmacy. We defined antiretroviral package categories based on the excellence of drug packaging and analyzed the number of pills and costs of drugs returned during a period of 1 year in a hospital-based HIV unit attending to 2,413 treated individuals. A total of 6,090 pills (34% of all returned antiretrovirals) - with a cost of 47,139.91 € - would be totally lost, mainly due to being packed up in the lowest efficiency packages. Newer treatments are packaged in low-excellence categories of packages, thus favoring the maintenance of these hidden costs in the near future. Therefore, costs of this low-efficiency drug packaging, where medication packages are started but not completed, in high-cost medications are substantial and should be properly addressed. Any improvement in the packaging by the manufacturer, and favoring the choice of drugs supplied through efficient packages (when efficacy, toxicity, and convenience are similar), should minimize the treatment expenditures paid by national health budgets.

    Full Text Available Global commitments aim to provide antiretroviral therapy (ART to 15 million people living with HIV by 2015, and recent studies have demonstrated the potential for widespread ART to prevent HIV transmission. Increasingly, countries are adapting their national guidelines to start ART earlier, for both clinical and preventive benefits. To maximize the benefits of ART in resource-limited settings, six key principles need to guide ART choice: simplicity, tolerability and safety, durability, universal applicability, affordability and heat stability. Currently available drugs, combined with those in late-stage clinical development, hold great promise to simplify treatment in the short term. Over the longer term, newer technologies, such as long-acting formulations and nanotechnology, could radically alter the treatment paradigm. This commentary reviews recommendations made in an expert consultation on treatment scale up in resource-limited settings.

    The appearance in the clinic of two to three new antiretroviral agents yearly since 1995 has permitted unprecedented advances in HIV treatment. This remarkable pace of drug development is a testimony to an extraordinary international effort involving scientists, clinicians, governments, community activists and industry dedicated to the rapid and safe development of novel therapies. New drugs present the opportunity to improve HIV therapy. They also create an enormous challenge to the clinician, who must constantly assimilate data on new drugs and incorporate this information into practical management strategies. Combination therapy has proven the most effective approach to treat HIV disease. The profound and sustained viral suppression achievable with combinations such as indinavir (IDV), lamivudine (3TC) and zidovudine (ZDV) have resulted in a dramatic shift in HIV treatment paradigms over the last year. The full potential of combination therapy with available drugs has yet to be realized as only a limited number of the possible combinations incorporating new drugs have been fully tested. Even drugs available for many years may have untapped potential. Didanosine (ddI) and stavudine (d4T), once thought to be contraindicated in combination because of their overlapping peripheral neuropathy toxicity, have proven well tolerated and effective. Combination therapy can increase antiviral suppression, prevent drug resistance, optimize drug exposure and simplify dosing, but it can also result in pharmacologic antagonism, subtherapeutic drug concentrations and unexpected toxicities. Clinical studies have confirmed in vitro studies showing pharmacologic antagonism for the combination of ZDV and d4T. Combining protease inhibitors with each other or with non-nucleoside reverse transcriptase inhibitors is complicated by effects both classes of drugs have on drug metabolism and clearance. These observations underline the importance of carefully conducted clinical studies to

    The human immunodeficiency virus (HIV) and the acquired immune deficiency syndrome (AIDS) represent a serious public health problem in Equatorial Guinea, with a prevalence of 6.2% among adults. the high-activity antiretroviral treatment (HAART) coverage data is 10 points below the overall estimate for Sub-Saharan Africa, and only 61% patients continue with HAART 12 months after it started. This study aims to assess HAART adherence and related factors in Litoral Province of Equatorial Guinea. In this cross-sectional study, socio-demographic and clinical data were collected at Regional Hospital of Bata, during June-July 2014. Adherence to treatment was assessed by using the Spanish version of CEAT-VIH. Bivariate and linear regression analyses were employed to assess HAART adherence-related factors. We interviewed 50 men (35.5%) and 91 women (64.5%), with a mean age of 47.7 ± 8.9 and 36.2 ± 11.2, respectively (p VIH score varied by ethnic group (p = .005). There was a positive correlation between CEAT-VIH score and current CD4 T-cells count (p = .013). The Cronbach's α value was 0.52. To our knowledge, this is the first study to assess HAART adherence in Equatorial Guinea. Internal reliability for CEAT-VIH was low, nonetheless the positive correlation between the CEAT-VIH score and the immunological status of patients add value to our findings. Our results serve as baseline for future research and will also assist stakeholders in planning and undertaking contextual and evidence-based policy initiatives.

    Full Text Available BACKGROUND: Antiretroviral therapy (ART has been scaled-up rapidly in Africa. Programme reports typically focus on loss to follow-up and mortality among patients receiving ART. However, little is known about linkage and retention in care of individuals prior to starting ART. METHODOLOGY: Data on adult residents from a periurban community in Cape Town were collected at a primary care clinic and hospital. HIV testing registers, CD4 count results provided by the National Health Laboratory System and ART registers were linked. A random sample (n = 885 was drawn from adults testing HIV positive through antenatal care, sexual transmitted disease and voluntary testing and counseling services between January 2004 and March 2009. All adults (n = 103 testing HIV positive through TB services during the same time period were also included in the study. Linkage to HIV care was defined as attending for a CD4 count measurement within 6 months of HIV diagnosis. Linkage to ART care was defined as initiating ART within 6 months of HIV diagnosis in individuals with a CD4 count ≤200 cells/µl taken within 6 months of HIV diagnosis. FINDINGS: Only 62.6% of individuals attended for a CD4 count measurement within 6 months of testing HIV positive. Individuals testing through sexually transmitted infection services had the best (84.1% and individuals testing on their own initiative (53.5% the worst linkage to HIV care. One third of individuals with timely CD4 counts were eligible for ART and 66.7% of those were successfully linked to ART care. Linkage to ART care was highest among antenatal care clients. Among individuals not yet eligible for ART only 46.3% had a repeat CD4 count. Linkage to HIV care improved in patients tested in more recent calendar period. CONCLUSION: Linkage to HIV and ART care was low in this poor peri-urban community despite free services available within close proximity. More efforts are needed to link VCT scale-up to subsequent care.

    HIV related mutations can be associated with decreased susceptibility to antiretrovirals and treatment failures. There is scarce information about HIV mutations in persons failing HIV treatment in North of Brazil. Our aim was to evaluate evolution of HIV subtypes and mutations patterns related to antiretroviral therapy in this region. We investigated HIV resistance profile in adults failing antiretroviral regimen in Northern Brazil from January, 2004, through December, 2013. Genotype data was evaluated through Stanford University algorithm. There were 377 genotypes from different individuals to evaluate. Resistance mutations were similar to worldwide reports and related to antiretroviral exposure. Most prevalent mutations in the reverse transcriptase gene were M184V (80.1%) and K130N (40.6%). Thymidine associated mutations were more frequent in multiexperienced patients. Most common protease mutations were M46I, V82A, I54V, L90M, I84V, M46L, and L76V. Subtype B was the most prevalent (90.7%). There were differences between subtypes B and non-B mutations. We documented for the first time subtypes and patterns of HIV associated mutations in Northern Brazil. A1 subtype was identified for the first time in this area. Depending on drug regimen and how experienced the patient is, an empirical switch of a failing antiretroviral treatment could be a reasonable option.

    Background Antiretroviral therapy (ART) restores immune function and reduces HIV-related adverse outcomes. But treatment failure erodes this advantage and leads to an increased morbidity and compromised quality of life in HIV patients. The aim of this study was to determine the prevalence and factors associated with first-line ART failure in HIV patients at the University of Gondar Teaching Hospital. Patients and methods A retrospective study was conducted on 340 adults who had started ART during the period of September 2011 to May 2015. Data regarding patients’ sociodemographics, baseline characteristics, and treatment-related information were collected through review of their medical charts. Data were analyzed using SPSS version 21. Descriptive statistics, cross-tabs, and binary and multiple logistic regressions were utilized. Page at ART initiation was 34.4 years. A total of 14 (4.1%) patients were found to have treatment failure. The median duration of treatment failure from initiation of treatment was 17.5 months (8–36 months). Poor adherence to treatment and low baseline CD4 cell count were found to be significant predictors of treatment failure. Conclusion The prevalence of first-line ART failure was 4.1%. Treatment failure was most likely to occur for the patients who had poor drug adherence and those who were delayed to start ART till their CD4 cell count became very low (<100 cells/mm3).

    Full Text Available BACKGROUND: In the developing world, the principal cause of death among HIV-infected patients is tuberculosis (TB. The initiation of antiretroviral therapy (ART during TB therapy significantly improves survival, however it is not known which barriers prevent eligible TB patients from initiating life-saving ART. METHOD: Setting. A South African township clinic with integrated tuberculosis and HIV services. Design. Logistic regression analyses of a prospective cohort of HIV-1 infected adults (≥18 years who commenced TB therapy, were eligible for ART, and were followed for 6 months. FINDINGS: Of 100 HIV-1 infected adults eligible for ART during TB therapy, 90 TB patients presented to an ART clinic for assessment, 66 TB patients initiated ART, and 15 TB patients died. 34% of eligible TB patients (95%CI: 25-43% did not initiate ART. Male gender and younger age (<36 years were associated with failure to initiate ART (adjusted odds ratios of 3.7 [95%CI: 1.25-10.95] and 3.3 [95%CI: 1.12-9.69], respectively. Death during TB therapy was associated with a CD4+ count <100 cells/µL. CONCLUSION: In a clinic with integrated services for tuberculosis and HIV, one-third of eligible TB patients--particularly young men--did not initiate ART. Strategies are needed to promote ART initiation during TB therapy, especially among young men.

    International tourism continues to increase worldwide, and people living with HIV and their clinicians are increasingly confronted with the problem of how to dose antiretroviral therapy during transmeridian air travel across time zones. No guidance on this topic currently exists. This review is a response to requests from patient groups for clear, practical and evidence-based guidance for travelling on antiretroviral therapy; we present currently available data on the pharmacokinetic forgiveness and toxicity of various antiretroviral regimens, and synthesize this data to provide guidelines on how to safely dose antiretrovirals when travelling across time zones.

    Full Text Available 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.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.

    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

  1. Interaction of antiretroviral medications with finasteride

    Directory of Open Access Journals (Sweden)

    D Ward

    2012-11-01

    Full Text Available Antiretroviral medications are known inhibitors and inducers of cytochrome p450 enzymes and can affect levels of non-HIV medications. Finasteride 1 mg (Propecia, which prevents the conversion of testosterone (T to dihydrotestosterone (DHT is commonly prescribed for prevention of hair loss. This medication is a substrate of p450 3A4. Its efficacy may therefore be affected by HIV medications which induce or inhibit this enzyme. Levels of DHT to prevent hair loss are not well established, but likely need to be<15–20 ng/dl, or a DHT/T ratio of<0.02. Observational analysis in a private practice, measuring DHT and T levels in patients on finasteride and various antiretrovirals 21 patients were identified. 7 patients were taking protease inhibitors and had DHT levels<12 ng/dL; DHT/T<0.20. Three of these patients decreased their finasteride dose to 1 mg every-other-day and still have DHT <10. 8 patients were taking potent p450 inducers (efavirenz or etravirine and had DHT levels between >20; DHT/T>0.025. Two of these patients increased the dose of finasteride to 2 mg/day and subsequently decreased DHT to 14 and 17. Two additional patients on efavirenz, however, had DHT levels of<15 without dose adjustment. Four patients taking nevirapine, a less potent inducer of p450 had DHT levels of<15, as did one patient on raltegravir, which does not affect CYP450. Antiretrovirals that affect CYP 3A4 may interact with finasteride. While it is unlikely that this interaction is dangerous, it may affect its efficacy of the finasteride. Evaluation of DHT/T levels, and/or dose adjustment of finasteride may be appropriate in men being treated for HIV.

    Full Text Available BACKGROUND: Although the importance of concurrent treatment for multidrug-resistant tuberculosis (MDR-TB and HIV co-infection has been increasingly recognized, there have been few studies reporting outcomes of MDR-TB and HIV co-treatment. We report final outcomes of comprehensive, integrated MDR-TB and HIV treatment in Lesotho and examine factors associated with death or treatment failure. METHODS: We reviewed clinical charts of all adult patients who initiated MDR-TB treatment in Lesotho between January 2008 and September 2009. We calculated hazard ratios (HR and used multivariable Cox proportional hazards regression to identify predictors of poor outcomes. RESULTS: Of 134 confirmed MDR-TB patients, 83 (62% were cured or completed treatment, 46 (34% died, 3 (2% transferred, 1 (1% defaulted, and 1 (1% failed treatment. Treatment outcomes did not differ significantly by HIV status. Among the 94 (70% patients with HIV co-infection, 53% were already on antiretroviral therapy (ART before MDR-TB treatment initiation, and 43% started ART a median of 16 days after the start of the MDR-TB regimen. Among HIV co-infected patients who died, those who had not started ART before MDR-TB treatment had a shorter median time to death (80 days vs. 138 days, p=0.065. In multivariable analysis, predictors of increased hazard of failure or death were low and severely low body mass index (HR 2.75, 95% confidence interval [CI] 1.27-5.93; HR 5.50, 95% CI 2.38-12.69, and a history of working in South Africa (HR 2.37, 95% CI 1.24-4.52. CONCLUSIONS: Favorable outcomes can be achieved in co-infected patients using a community-based treatment model when both MDR-TB and HIV disease are treated concurrently and treatment is initiated promptly.

Patients were classified as LTFU if they did not return >60 days from their expected visit. Pharmacy refill rates were calculated and used to assess non-adherence. We identified risk factors associated with LTFU and non-adherence using Cox and Generalized Estimating Equation (GEE regressions, respectively. Of 5,760 patients initiating ART, 26% were LTFU. Female gender (p 350 and 2 hours to the clinic (p = 0.03, had total ART duration of >6 months (p200 at ART initiation were at a higher risk of non-adherence. Patients who disclosed their HIV status to spouse/family (p = 0.01 and were treated with tenofovir-containing regimens (p < or = 0.001 were more likely to be adherent. CONCLUSIONS: These findings formed the basis for implementing multiple pre-treatment visit preparation that promote disclosure and active community outreaching to support retention and adherence. Expansion of treatment access points of care to communities to diminish travel time may have a positive impact on adherence.

    Full Text Available Abstract Background Our intention was to analyze demographic and contextual factors associated with sexual risk taking among HIV-infected patients on antiretroviral treatment (ART in Africa's largest informal urban settlement, Kibera in Nairobi, Kenya. Methods We used a cross-sectional survey in a resource-poor, urban informal settlement in Nairobi; 515 consecutive adult patients on ART attending the African Medical and Research Foundation clinic in Kibera in Nairobi were included in the study. Interviewers used structured questionnaires covering socio-demographic characteristics, time on ART, number of sexual partners during the previous six months and consistency of condom use. Results Twenty-eight percent of patients reported inconsistent condom use. Female patients were significantly more likely than men to report inconsistent condom use (aOR 3.03; 95% CI 1.60-5.72. Shorter time on ART was significantly associated with inconsistent condom use. Multiple sexual partners were more common among married men than among married women (adjusted OR 4.38; 95% CI 1.82-10.51. Conclusions Inconsistent condom use was especially common among women and patients who had recently started ART, i.e., when the risk of HIV transmission is higher. Having multiple partners was quite common, especially among married men, with the potential of creating sexual networks and an increased risk of HIV transmission. ART needs to be accompanied by other preventive interventions to reduce the risk of new HIV infections among sero-discordant couples and to increase overall community effectiveness.

    Full Text Available 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.

  12. LEP dismantling starts

    2000-01-01

    Since the end of November, various teams have been getting stuck into dismantling the LEP accelerator and its four experiments. After making the installations safe, the dismantling and removal of 40,000 tonnes of equipment is underway. Down in the tunnel, it is a solemn moment. It is 10 o'clock on 13 December and Daniel Regin, one of those heading the dismantling work, moves in on a magnet, armed with a hydraulic machine. Surrounded by teams gathered there for a course in dismantling, he makes the first cut into LEP. The great deconstruction has begun. In little over than a year, the accelerator will have been cleared away to make room for its successor, the LHC. The start of the operation goes back to 27 November. Because before setting about the machine with hydraulic shears and monkey wrenches, LEP had first to be made safe - it was important to make sure the machine could be taken apart without risk. All the SPS beam injection systems to LEP were cut off. The fluids used for cooling the magnets and superc...

  13. An impressive start

    CERN Multimedia

    2011-01-01

    This has been an excellent week for the LHC, with a succession of fills rapidly increasing the number of proton bunches to 194 per beam. This has allowed the experiments to reach a peak luminosity of 2.5 × 1032 cm-2s-1, thereby surpassing the record for 2010 where we reached 2.0 × 1032 cm-2s-1. At the time of writing, the integrated luminosity delivered by the LHC in 2011 is around 28 inverse picobarns, which is already more than half of the total 2010 dataset.   These are impressive numbers, but what impresses me most is how quickly the LHC operators are now able to turn the machine around between fills, and how well LHC running has been incorporated into the overall operation of CERN’s accelerator complex. The flexibility of the LHC was illustrated on Thursday when we started a short phase of running at 1.38 TeV per beam, equivalent to the energy-per-nucleon of a lead-ion run. This lower energy data will be used by the experiments, in particular by ALICE, to compare...

    2004-01-01

    The first large active detector component was lowered into the ATLAS cavern on 1st March. It consisted of the 8 modules forming the lower part of the central barrel of the tile hadronic calorimeter. The work of assembling the barrel, which comprises 64 modules, started the following day. Two road trailers each with 64 wheels, positioned side by side. This was the solution chosen to transport the lower part of the central barrel of ATLAS' tile hadronic calorimeter from Building 185 to the PX16 shaft at Point 1 (see Figure 1). The transportation, and then the installation of the component in the experimental cavern, which took place over three days were, to say the least, rather spectacular. On 25 February, the component, consisting of eight 6-metre modules, was loaded on to the trailers. The segment of the barrel was transported on a steel support so that it wouldn't move an inch during the journey. On 26 February, once all the necessary safety checks had been carried out, the convoy was able to leave Buildi...

  15. Diagnosis, antiretroviral therapy, and emergence of resistance to antiretroviral agents in HIV-2 infection: a review

    2003-02-01

    Full Text Available Human immunodeficiency virus type 1 (HIV-1 and type 2 (HIV-2 are the causative agents of AIDS. HIV-2 is prevalent at moderate to high rates in West African countries, such as Senegal, Guinea, Gambia, and Cape Verde. Diagnosis of HIV-2 is made with a positive HIV-1/HIV-2 ELISA or simple/rapid assay, followed by one or two confirmatory tests specific for HIV-2. Following CD4+ T cell counts, HIV-2 viral burden and clinical signs and symptoms of immunodeficiency are beneficial in monitoring HIV-2 disease progression. Although non-nucleoside reverse transcriptase inhibitors are ineffective in treating HIV-2, nucleoside reverse transcriptase inhibitors and protease inhibitors can be effective in dual and triple antiretroviral regimens. Their use can decrease HIV-2 viral load, increase CD4+ T cell counts and improve AIDS-related symptoms. HIV-2 resistance to various nucleoside reverse transcriptase inhibitors and protease inhibitors, including zidovudine, lamivudine, ritonavir and indinavir, has been identified in some HIV-2 infected patients on antiretroviral therapy. The knowledge of HIV-2 peculiarities, when compared to HIV-1, is crucial to helping diagnose and guide the clinician in the choice of the initial antiretroviral regimen and for monitoring therapy success.

    Highly active antiretroviral therapy (HAART) is used in patients infected with HIV. This treatment has been shown to significantly decrease opportunist infections such as those caused by viruses, fungi and particularly, protozoa. The use of HAART in HIV-positive persons is associated with immune reconstitution as well as decreased prevalence of oral candidiasis and candidal carriage.

    Full Text Available Background: Acquired immune deficiency syndrome (AIDS is now considered as a manageable chronic illness. There has been a dramatic reduction in human immunodeficiency virus (HIV related morbidity and mortality due to antiretroviral therapy. A high level of adherence (>95% is required for antiretroviral therapy to be effective. There are many barriers to adherence in both developed and developing countries. Aim: The aim of our study was to determine adherence levels and factors influencing adherence to antiretroviral therapy among people living with HIV. Materials and Methods: Using a cross-sectional study design, 116 HIV positive patients receiving antiretroviral therapy for at least 1 year were interviewed using a semi structured questionnaire. The collected data was analyzed using Statistical Product and Service Solutions (SPSS version 11.5. Chi-square test was done. A P value of < 0.05 was considered statistically significant. Results: Of 116 participants, 63.7% reported adherence ≥ 95%. Mean adherence index was 91.25%. Financial constraints, forgetting to take medication, lack of family care, depression, alcohol use, social stigma and side effects to antiretroviral therapy were barriers for adherence in our study. Conclusion: Adherence to antiretroviral therapy in south India is suboptimal. Intensive adherence counseling should be provided to all patients before initiation ofantiretroviral therapy. Health care providers must identify possible barriers to adherence at the earliest and provide appropriate solutions.

    Full Text Available Abstract Objective To evaluate the feasibility of a large immediate versus deferred antiretroviral therapy (ART study in children. Methods We conducted an open-label pilot randomized clinical trial study in 43 Thai children with CD4 15 to 24% of starting generic AZT/3TC/NVP immediately (Arm 1 or deferring until CD4 Results Recruitment took 15 months. Twenty-six of 69 (37.7% were not eligible due mainly to low CD4%. Twenty four and 19 were randomized to arms 1 and 2 respectively. All accepted the randomized arm; however, 3 in arm 1 stopped ART and 1 in arm 2 refused to start ART. Ten/19 (53% in arm 2 started ART. At baseline, median age was 4.8 yrs, CDC A:B were 36:7, median CD4 was 19% and viral load was 4.8 log. All in arm 1 and 17/19 in arm 2 completed the study (median of 134 weeks. No one had AIDS or death. Four in immediate arm had tuberculosis. Once started on ART, deferred arm children achieved similar CD4 and viral load response as the immediate arm. Adverse events were similar between arms. The deferred arm had a 26% ART saving. Conclusion Almost 40% of children were not eligible due mainly to low CD4% but adherence to randomized treatment and retention in trial were excellent. A larger study to evaluate when to start ART is feasible.

    Full Text Available Abstract Background Rifampicin reduces the plasma concentrations of nevirapine in human immunodeficiency virus (HIV and tuberculosis (TB co-infected patients, who are administered these drugs concomitantly. We conducted a prospective interventional study to assess the efficacy of nevirapine-containing highly active antiretroviral treatment (HAART when co-administered with rifampicin-containing antituberculosis treatment (ATT and also measured plasma nevirapine concentrations in patients receiving such a nevirapine-containing HAART regimen. Methods 63 cases included antiretroviral treatment naïve HIV-TB co-infected patients with CD4 counts less than 200 cells/mm3 started on rifampicin-containing ATT followed by nevirapine-containing HAART. In control group we included 51 HIV patients without tuberculosis and on nevirapine-containing HAART. They were assessed for clinical and immunological response at the end of 24 and 48 weeks. Plasma nevirapine concentrations were measured at days 14, 28, 42 and 180 of starting HAART. Results 97 out of 114 (85.1% patients were alive at the end of 48 weeks. The CD4 cell count showed a mean increase of 108 vs.113 cells/mm3 (p=0.83 at 24 weeks of HAART in cases and controls respectively. Overall, 58.73% patients in cases had viral loads of less than 400 copies/ml at the end of 48 weeks. The mean (± SD Nevirapine concentrations of cases and control at 14, 28, 42 and 180 days were 2.19 ± 1.49 vs. 3.27 ± 4.95 (p = 0.10, 2.78 ± 1.60 vs. 3.67 ± 3.59 (p = 0.08, 3.06 ± 3.32 vs. 4.04 ± 2.55 (p = 0.10 respectively and 3.04 μg/ml (in cases. Conclusions Good immunological and clinical response can be obtained in HIV-TB co-infected patients receiving rifampicin and nevirapine concomitantly despite somewhat lower nevirapine trough concentrations. This suggests that rifampicin-containing ATT may be co administered in resource limited setting with nevirapine-containing HAART regimen without substantial reduction in

    This paper investigates the effects of school starting age on crime while relying on variation in school starting age induced by administrative rules; we exploit that Danish children typically start first grade in the calendar year they turn seven, which gives rise to a discontinuity in children’s...... school starting age. Analyses are carried out using register-based Danish data. We find that higher age at school start lowers the propensity to commit crime, but that this reduction is caused by incapacitation while human capital accumulation is unaffected. Importantly, we also find that the individuals...

  2. Pregnancy and virologic response to antiretroviral therapy in South Africa.

    Daniel Westreich

    Full Text Available BACKGROUND: Although women of reproductive age are the largest group of HIV-infected individuals in sub-Saharan Africa, little is known about the impact of pregnancy on response to highly active antiretroviral therapy (HAART in that setting. We examined the effect of incident pregnancy after HAART initiation on virologic response to HAART. METHODS AND FINDINGS: We evaluated a prospective clinical cohort of adult women who initiated HAART in Johannesburg, South Africa between 1 April 2004 and 30 September 2009, and followed up until an event, death, transfer, drop-out, or administrative end of follow-up on 31 March 2010. Women over age 45 and women who were pregnant at HAART initiation were excluded from the study; final sample size for analysis was 5,494 women. Main exposure was incident pregnancy, experienced by 541 women; main outcome was virologic failure, defined as a failure to suppress virus to ≤ 400 copies/ml by six months or virologic rebound >400 copies/ml thereafter. We calculated adjusted hazard ratios using marginal structural Cox proportional hazards models and weighted lifetable analysis to calculate adjusted five-year risk differences. The weighted hazard ratio for the effect of pregnancy on time to virologic failure was 1.34 (95% confidence limit [CL] 1.02, 1.78. Sensitivity analyses generally confirmed these main results. CONCLUSIONS: Incident pregnancy after HAART initiation was associated with modest increases in both relative and absolute risks of virologic failure, although uncontrolled confounding cannot be ruled out. Nonetheless, these results reinforce that family planning is an essential part of care for HIV-positive women in sub-Saharan Africa. More work is needed to confirm these findings and to explore specific etiologic pathways by which such effects may operate.

    Full Text Available BACKGROUND: In South Africa in 2010, about 340,000 children under the age of 15 were infected with HIV. We describe the increase in the treatment of South African pediatric HIV-infected patients assisted by the President's Emergency Plan for AIDS Relief (PEPFAR from 2004 to 2010. METHODS: We reviewed routine program data from PEPFAR-funded implementing partners among persons receiving antiretroviral treatment age 15 years old and less. Data quality was assessed during the reporting period by program officials through routine analysis of trends and logic checks. Based on UNAIDS estimated mortality rates of untreated HIV-infected children, we calculated the number of deaths averted and life-years gained in children under five receiving PEPFAR-assisted antiretroviral treatment. RESULTS: From October 2004 through September 2010, the number of children newly initiated on antiretroviral treatment in PEPFAR-assisted programs increased from 154 to 2,641 per month resulting in an increase from 2,412 children on antiretroviral treatment in September 2005 to 79,416 children in September 2010. Of those children who initiated antiretroviral treatment before September 2009, 0-4 year olds were 1.4 (95% CI: 1.3-1.5 times as likely to transfer out of the program or die as 5-14 year olds; males were 1.3 (95% CI: 1.0-1.7 times as likely to stop treatment as females. Approximately 27,548 years of life were added to children under-five years old from PEPFAR-assisted antiretroviral treatment. CONCLUSIONS: Pediatric antiretroviral treatment in South Africa has increased substantially. However, additional case-finding and a further acceleration in the implementation of pediatric care and treatment services is required to meet the current treatment need.

    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 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 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

    2009-10-01

    Full Text Available Abstract Background The optimal stage for initiating antiretroviral therapies in HIV-1 bearing patients is still a matter of debate. Methods We present computer simulations of HIV-1 infection aimed at identifying the pro et contra of immediate as compared to deferred Highly Active Antiretroviral Therapy (HAART. Results Our simulations highlight that a prompt specific CD8+ cytotoxic T lymphocytes response is detected when therapy is delayed. Compared to very early initiation of HAART, in deferred treated patients CD8+ T cells manage to mediate the decline of viremia in a shorter time and, at interruption of therapy, the virus experiences a stronger immune pressure. We also observe, however, that the immunological effects of the therapy fade with time in both therapeutic regimens. Thus, within one year from discontinuation, viral burden recovers to the value at which it would level off in the absence of therapy. In summary, simulations show that immediate therapy does not prolong the disease-free period and does not confer a survival benefit when compared to treatment started during the chronic infection phase. Conclusion Our conclusion is that, since there is no therapy to date that guarantees life-long protection, deferral of therapy should be preferred in order to minimize the risk of adverse effects, the occurrence of drug resistances and the costs of treatment.

    Procurement, the country-level process of ordering antiretrovirals (ARVs), and supply chain management, the mechanism by which they are delivered to health-care facilities, are critical processes required to move ARVs from manufacturers to patients. To provide a glimpse into the ARV procurement and supply chain, the following pages provide an overview of the primary stakeholders, principal operating models, and policies and regulations involved in ARV procurement. Also presented are key challenges that need to be addressed to ensure that the supply chain is not a barrier to the goal of universal coverage. This article will cover the steps necessary to order and distribute ARVs, including different models of delivery, key stakeholders involved, strategic considerations that vary depending on context and policies affecting them. The single drug examples given illustrate the complications inherent in fragmented supply and demand-driven models of procurement and supply chain management, and suggest tools for navigating these hurdles that will ultimately result in more secure and reliable ARV provision. Understanding the dynamics of ARV supply chain is important for the global health community, both to ensure full and efficient treatment of persons living with HIV as well as to inform the supply chain decisions for other public health products.

    Implementation of START negotiations and agreement invokes an image of an evolving arms control agenda in which the achievements of the START process will provide the foundations for genuine disarmament. The contributions of START I and START II (to date unratified) are indeed significant. Once implemented in 3003, the new agreement will reduce the two nations' (USA and Russia) strategic inventories to some 7000 weapons - less than one-third of the levels established by the 1991 Strategic Reduction Talks. More important, it will completely eliminate both sides' most destabilizing weapons - land based missiles with multiple independently targetable warheads

    Full Text Available Abstract Background Antiretroviral scale-up is increasing in resource-constrained settings. To date, few studies have explored the barriers and facilitators of adherence to ART in these settings. Facilitators and barriers of antiretroviral adherence in Peru are not completely understood. Methods At two clinics that serve a large number of HIV-positive individuals in Lima, Peru, 31 in-depth interviews were carried out in 2006 with adult HIV-positive individuals receiving ART. Purposive sampling was used to recruit the participants. Interviews were transcribed and coded using two Spanish-speaking researchers and a content analysis approach to identify themes in the data. Results Among the participants, 28/31 (90% were male, 25/31 (81% were self-identified as mestizo, and 19/31 (61% had an education above high school. The most frequently discussed barriers to adherence included side effects, simply forgetting, inconvenience, dietary requirements, being away from home, and fear of disclosure/stigma. The most frequently discussed facilitators to adherence included having a fixed routine, understanding the need for compliance, seeing positive results, treatment knowledge, and faith in treatment. Conclusions Overall, these findings were similar to the facilitators and challenges experienced by individuals on ART in other resource constrained settings. Further treatment support tools and networks should be developed to decrease the challenges of ART adherence for HIV-positive individuals in Lima, Peru.

    Dickinson, Laura; Khoo, Saye; Back, David

    2010-01-01

    Current antiretroviral treatment has allowed HIV infection to become a chronic manageable condition with many HIV patients living longer. However, available antiretrovirals are not without limitations, for example the development of resistance and adverse effects. Consequently, new drugs in existing and novel classes are urgently required to provide viable treatment options to patients with few remaining choices. Darunavir, etravirine, maraviroc and raltegravir have been recently approved for treatment-experienced patients and other agents such as rilpivirine, vicriviroc and elvitegravir are currently under phase III study. Clinical studies are necessary to optimise potential treatment combinations and to manage drug-drug interactions to help avoid toxicity or therapy failure. This review aims to summarise the pharmacokinetics and key drug-drug interaction studies for newly available antiretrovirals and those in development. Further information regarding drug-drug interactions of well established antiretrovirals and those recently approved are readily available online at sites such as http://www.hiv-druginteractions.org, http://www.clinicaloptions.com/hiv, http://hivinsite.ucsf.edu. This article forms part of a special issue of Antiviral Research marking the 25th anniversary of antiretroviral drug discovery and development, Vol 85, issue 1, 2010.

    French Guiana is the French territory where the HIV epidemic is most preoccupying. In Cayenne, the mother to child HIV transmission rate was 6% in 2006-2008. Despite free testing and treatment, HIV pregnant women often have delayed or insufficient access to care. The aim of this study was to identify predictive factors of antiretroviral treatmentFrench Guiana) and then to describe their attitudes, practices, and beliefs regarding HIV/AIDS. A case control study was conducted including all deliveries in Cayenne from 2003 to 2010. For each case, a standardized questionnaire including epidemiological, clinical, and biological data was administered. The analysis first described the summary statistics and then bivariate analysis studied the relation of each variable with the outcome. Multivariate analysis adjusted for the confounding factors. Thirty-three women in the first group and 96 in the control group were included in the study. Women born in French Guiana (OR = 5, IC95% = 1.22-20.86, p=0.027) had a high risk of treatment<4 weeks. The other factors associated with treatment<4 weeks in our study were benefiting from food parcels (OR = 12.72, IC95% = 2.07-78.14, p=0.006), consulting a traditional healer when sick (OR = 9.86, IC95% = 2.57-37.88, p= < 0.001), and drug use (OR = 6.27, IC95% = 1.26-31.13, p=0.025). These predictive factors should be considered in prevention programs against mother to child transmission of HIV.

  19. Persistent HIV-1 replication during antiretroviral therapy

    Science.gov (United States)

    Martinez-Picado, Javier; Deeks, Steven G.

    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.

    Adherence continues to be a major barrier to successful treatment with highly active antiretroviral therapy (HAART) for HIV-infected individuals. HIV-infected adolescents and young adults face a lifetime of treatment with HAART. Often, individuals who struggle with adherence to HAART face multiple barriers that would therefore impact on the success of any single modality intervention. Thus, we conducted a cross-sectional, observational study to determine the prevalence of personal barriers to...

    2010-04-01

    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.

  6. The (political) economics of antiretroviral treatment in developing countries.

    Nattrass, Nicoli J

    2008-12-01

    Despite unprecedented international mobilisation to support universal provision of highly active antiretroviral therapy (HAART), national governments continue to play the key role in determining access to treatment. Whereas some AIDS-affected countries have performed as well as or better than expected given their level of development, institutional characteristics and demographic challenges (e.g. Thailand and Brazil), others (notably South Africa) have not. This article argues that the 'economics' of antiretroviral drug delivery is at heart a political-economy of access to treatment. It depends on commitment on the part of national governments to negotiate with pharmaceutical companies over patented antiretroviral drug prices, on their policy towards compulsory licensing, and on the approach they adopt to delivering HAART. Civil society has an important role to play in encouraging governments to become, and remain, committed to taking action to ensure sustainable and widespread access to HAART.

    Full Text Available 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.

    2014-07-01

    Full Text Available Antiretroviral therapy has been associated with side effects, either from the drug itself or in conjunction with the effects of human immunodeficiency virus infection. Here, we evaluated the side effects of the protease inhibitor (PI indinavir in hamsters consuming a normal or high-fat diet. Indinavir treatment increased the hamster death rate and resulted in an increase in triglyceride, cholesterol and glucose serum levels and a reduction in anti-oxLDL auto-antibodies. The treatment led to histopathological alterations of the kidney and the heart. These results suggest that hamsters are an interesting model for the study of the side effects of antiretroviral drugs, such as PIs.

    2016-05-01

    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.

  14. Immune reconstitution inflammatory syndrome after initiating highly active antiretroviral therapy in HIV-infected children

    International Nuclear Information System (INIS)

    The outcome of HIV infection has improved since the widespread availability of highly active antiretroviral therapy (HAART). Some patients, however, develop a clinical and radiological deterioration following initiation of HAART due to either the unmasking of occult subclinical infection or an enhanced inflammatory response to a treated infection. This phenomenon is believed to result from the restored ability to mount an immune response and is termed immune reconstitution inflammatory syndrome (IRIS) or immune reconstitution disease. IRIS is widely reported in the literature in adult patients, most commonly associated with mycobacterial infections. There is, however, a paucity of data documenting the radiological findings of IRIS in children. Radiologists need to be aware of this entity. As a diagnosis of exclusion it is essential that the radiological findings be assessed in the context of the clinical presentation. This article reviews the common clinical and radiological manifestations of IRIS in HIV-infected children. (orig.)

  17. Maximizing the benefits of antiretroviral therapy for key affected populations

    Directory of Open Access Journals (Sweden)

    Ian R Grubb

    2014-07-01

    Full Text Available 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

  18. STARTing Again: What Happens After START I Expires?

    International Nuclear Information System (INIS)

    The Strategic Arms Reduction Treaty (START I), a seminal arms control agreement that substantially reduced the levels of deployed strategic nuclear arms in the United States and Russia, will expire in December 2009. At this time, it is unclear what - if anything - will replace it. While the treaty remains relevant, more than a simple extension is appropriate. Instead the authors advocate for a successor regime that builds on the START I legacy but does not rely on the traditional tools of arms control. This paper examines the strategic context in which a successor regime would be developed and proposes several recommendations for future action

    The cost of HIV care in European countries is high. Direct medical costs, in France, have been estimated at 500,000 Euros per patient's lifetime (20,000 Euros/year/patient). Overall, 73% of these costs are related to antiretroviral treatments. In the current financial crisis context, some European countries are beginning to make economic decisions on the drugs to be used. These approaches are likely to become more frequent. It is obviously essential to prescribe the most effective, appropriate, best tolerated, and easy-to-use antiretroviral treatments to patients. However, while taking the above into consideration, and if various treatment options or combinations are available, cost should also be considered in the treatment choice. One may thus reflect on the use of generic antiretroviral agents as they have just been launched in France. We aimed to review the cost and cost-effectiveness of generic antiretroviral drugs and to review treatment strategies other than generic drugs that could help reduce HIV-related costs. HIV clinicians should consider treatment costs to avoid any future coercive measures.

    Full Text Available Abstract Background The HIV and AIDS epidemic in Malawi poses multiple challenges from an equity perspective. It is estimated that 12% of Malawians are living with HIV or AIDS among the 15-49 age group. This paper synthesises available information to bring an equity lens on Counselling and Testing (CT and Antiretroviral Therapy (ART policy, practice and provision in Malawi. Methods A synthesis of a wide range of published and unpublished reports and studies using a variety of methodological approaches was undertaken. The analysis and recommendations were developed, through consultation with key stakeholders in Malawi. Findings At the policy level Malawi is unique in having an equity in access to ART policy, and equity considerations are also included in key CT documents. The number of people accessing CT has increased considerably from 149,540 in 2002 to 482,364 in 2005. There is urban bias in provision of CT and more women than men access CT. ART has been provided free since June 2004 and scale up of ART provision is gathering pace. By end December 2006, there were 85,168 patients who had ever started on ART in both the public and private health sector, 39% of the patients were male while 61% were female. The majority of patients were adults, and 7% were children, aged 14 years or below. Despite free ART services, patients, especially poor rural patients face significant barriers in access and adherence to services. There are missed opportunities in strengthening integration between CT and ART and TB, Sexually Transmitted Infections (STI and maternal health services. Conclusion To promote equitable access for CT and ART in Malawi there is need to further invest in human resources for health, and seize opportunities to integrate CT and ART services with tuberculosis, sexually transmitted infections and maternal health services. This should not only promote access to services but also ensure that resources available for CT and ART strengthen

    Full Text Available Introduction: The current expansion of antiretroviral treatment (ART in the developing world without routine virological monitoring still raises concerns on the outcome of the strategy in terms of virological success and drug resistance burden. We assessed the virological outcome and drug resistance mutations in patients with 36 months’ ART experience, and monitored according to the WHO public health approach in Cameroon. Methods: We consecutively recruited between 2008 and 2009 patients attending a national reference clinic in Yaoundé – Cameroon, for their routine medical visits at month 36±2. Observance data and treatment histories were extracted from medical records. Blood samples were collected for viral load (VL testing and genotyping of drug resistance when HIV-1 RNA≥1000 copies/ml. Results: Overall, 376 HIV-1 infected adults were recruited during the study period. All, but four who received PMTCT, were ART-naïve at treatment initiation, and 371/376 (98.7% started on a first-line regimen that included 3TC +d4T/AZT+NVP/EFV. Sixty-six (17.6% patients experienced virological failure (VL≥1000 copies/ml and 53 carried a resistant virus, thus representing 81.5% (53/65 of the patients who failed. Forty-two out of 53 were resistant to nucleoside and non-nucleoside reverse-transcriptase inhibitors (NRTIs+NNRTIs, one to protease inhibitors (PI and NNRTIs, two to NRTIs only and eight to NNRTIs only. Among patients with NRTI resistance, 18/44 (40.9% carried Thymidine Analog Mutations (TAMs, and 13/44 (29.5% accumulated at least three NRTI resistance mutations. Observed NNRTI resistance mutations affected drugs of the regimen, essentially nevirapine and efavirenz, but several patients (10/51, 19.6% accumulated mutations that may have compromised etravirine use. Conclusions: We observed a moderate level of virological failure after 36 months of treatment, but a high proportion of patients who failed developed drug resistance. Although we

    Full Text Available Background: Retention in HIV care ensures delivery of services like secondary prevention, timely initiation of treatment, support, and care on a regular basis. The data on retention in pre antiretroviral therapy (ART care in India is scanty. Materials and Methods: Antiretroviral naοve HIV-infected adult patients registered between January 2011 and March 2012 in HIV care (pre-ART were included in the study. The follow-up procedures were done as per the national guidelines. Patients who did not report to the clinic for 1 year were considered as pre-ART lost to follow-up (pre-ART LFU. They were contacted either telephonically or by home visits. Logistic regression analysis was done to find out factors associated with pre-ART loss to follow-up. Results: A total of 689 antiretroviral naοve adult patients were registered in the HIV care. Fourteen (2% patients died and 76 (11% were LFU till March 2013. The multivariate analysis showed that baseline CD4 count >350 cells/mm 3 (P < 0.01 and illiteracy (P = 0.044 were significantly associated with LFU. Of the total pre-ART LFUs, 35 (46.1% informed that they would visit the clinic at their convenient time. NGOs that referred 16 female sex workers (FSWs who were LFU (21.1% informed that they would make efforts to refer them to the clinic. Conclusion: Higher CD4 count and illiteracy were significantly associated with lower retention in pre-ART care. Developing effective "retention package" for patients and strengthening linkage strategies between key sub-population such as FSWs and ART programming will help to plug the leaky cascade in HIV care.

    More than 50 % of women living with HIV in low- and middle-income countries are of reproductive age, but there are limitations to the administration of oral contraception for HIV-infected women receiving antiretroviral therapy due to drug-drug interactions caused by metabolism via the cytochrome P450 isoenzymes and glucuronidation. However, with the development of newer antiretrovirals that use alternative metabolic pathways, options for contraception in HIV-positive women are increasing. This paper aims to review the literature on the pharmacokinetics and pharmacodynamics of oral hormonal contraceptives when given with antiretroviral agents, including those currently used in developed countries, older ones that might still be used in salvage regimens, or those used in resource-limited settings, as well as newer drugs. Nucleos(t)ide reverse transcriptase inhibitors (NRTIs), the usual backbone to most combined antiretroviral treatments (cARTs) are characterised by a low potential for drug-drug interactions with oral contraceptives. On the other hand non-NRTIs (NNRTIs) and protease inhibitors (PIs) may interact with oral contraceptives. Of the NNRTIs, efavirenz and nevirapine have been demonstrated to cause drug-drug interactions; however, etravirine and rilpivirine appear safe to use without dose adjustment. PIs boosted with ritonavir are not recommended to be used with oral contraceptives, with the exception of boosted atazanavir which should be used with doses of at least 35 µg of estrogen. Maraviroc, an entry inhibitor, is safe for co-administration with oral contraceptives, as are the integrase inhibitors (INIs) raltegravir and dolutegravir. However, the INI elvitegravir, which is given in combination with cobicistat, requires a dose of estrogen of at least 30 µg. Despite the growing evidence in this field, data are still lacking in terms of large cohort studies, randomised trials and correlations to real clinical outcomes, such as pregnancy rates, in women

    Full Text Available Abstract Background There is little knowledge regarding the prevalence and nature of renal impairment in African populations initiating antiretroviral treatment, nor evidence to inform the most cost effective methods of screening for renal impairment. With the increasing availability of the potentially nephrotixic drug, tenofovir, such information is important for the planning of antiretroviral programmes Methods (i Retrospective review of the prevalence and risk factors for impaired renal function in 2189 individuals initiating antiretroviral treatment in a rural African setting between 2004 and 2007 (ii A prospective study of 149 consecutive patients initiating antiretrovirals to assess the utility of urine analysis for the detection of impaired renal function. Severe renal and moderately impaired renal function were defined as an estimated GFR of ≤ 30 mls/min/1.73 m2 and 30–60 mls/min/1.73 m2 respectively. Logistic regression was used to determine odds ratio (OR of significantly impaired renal function (combining severe and moderate impairment. Co-variates for analysis were age, sex and CD4 count at initiation. Results (i There was a low prevalence of severe renal impairment (29/2189, 1.3% 95% C.I. 0.8–1.8 whereas moderate renal impairment was more frequent (287/2189, 13.1% 95% C.I. 11.6–14.5 with many patients having advanced immunosuppression at treatment initiation (median CD4 120 cells/μl.

Urine analysis alone may be inadequate for identification of those with impaired renal function where resources for biochemistry are limited.

    The aim of this study was to evaluate possible changes in predisposing factors in sexual preventive behaviors that could result from the availability of an efficient new antiretroviral therapy. A total of 136 young adults were randomly assigned a vignette to read describing AIDS as a lethal or chronic disease. After reading the vignette, the participants completed a self-administered questionnaire assessing the psychosocial determinants of intention to use a condom with a new sexual partner. The variables were measured according to Ajzen's (1985, 1988, 1991) theory of planned behavior and Triandis's (1977) theory of interpersonal behavior. The experimental manipulation was more successful when the disease was described as lethal (66 of the 68 subjects) rather than chronic (30 of the 68 subjects). For the 96 participants who correctly identified the expected outcome of the disease presented in the vignette, a significant difference in intention was found between the two experimental situations (p intention to use condoms on the psychosocial variables yielded an adjusted R2 of .62. Perceived behavioral control, social norms, personal normative belief and anticipated affective reaction were the significant variables explaining this intention. The results suggest that intention to use condoms with a new sexual partner is likely to be modified by the expected outcome of the disease, that is, whether lethal or chronic. Thus, it is suggested that interventions aimed at young adults take into account the impacts the new antiretroviral treatments are likely to have on preventive behaviors.

  17. Systematic review of antiretroviral-associated lipodystrophy: lipoatrophy, but not central fat gain, is an antiretroviral adverse drug reaction.

    Directory of Open Access Journals (Sweden)

    Reneé de Waal

    Full Text Available BACKGROUND: Lipoatrophy and/or central fat gain are observed frequently in patients on antiretroviral therapy (ART. Both are assumed to be antiretroviral adverse drug reactions. METHODS: We conducted a systematic review to determine whether fat loss or gain was more common in HIV-infected patients on ART than in uninfected controls; was associated with specific antiretrovirals; and would reverse after switching antiretrovirals. RESULTS: Twenty-seven studies met our inclusion criteria. One cohort study reported more lipoatrophy, less subcutaneous fat gain, but no difference in central fat gain in HIV-infected patients on ART than in controls. Randomised controlled trials (RCTs showed more limb fat loss (or less fat gain with the following regimens: stavudine (versus other nucleoside reverse transcriptase inhibitors (NRTIs; efavirenz (versus protease inhibitors (PIs; and NRTI-containing (versus NRTI-sparing. RCTs showed increased subcutaneous fat after switching to NRTI-sparing regimens or from stavudine/zidovudine to abacavir/tenofovir. There were no significant between-group differences in trunk and/or visceral fat gain in RCTs of various regimens, but results from efavirenz versus PI regimens were inconsistent. There was no significant between-group differences in central fat gain in RCTs switched to NRTI-sparing regimens, or from PI-containing regimens. CONCLUSIONS: There is clear evidence of a causal relationship between NRTIs (especially thymidine analogues and lipoatrophy, with concomitant PIs possibly having an ameliorating effect or efavirenz causing additive toxicity. By contrast, central fat gain appears to be a consequence of treating HIV infection, because it is not different from controls, is not linked to any antiretroviral class, and doesn't improve on switching.

    írus da imunodeficiência humana.PURPOSE: to evaluate experimentally the effects of antiretroviral drugs used alone and in association upon the fertility of pregnant Wistar rats and the perinatal effects on the offspring. METHODS: adult female pregnant Wistar rats weighing 200-230 g were used. The antiretroviral drugs zidovudine (AZT, lamivudine (3TC and nelfinavir (NFV were used alone and in association at daily doses of ten times the dose normally used in pregnant women, proportionally to the animal's body weight. Seven groups were studied, including the control one. The experiment started on day 0 and the pregnant animals were sacrificed on day 21. The alive and dead fetuses, the total implantation sites and the total numbers of corporea lutea were used to calculate the fertility values. The statistical analysis was performed by Student's t test and by the Mann-Whitney test. RESULTS: there were no significant statistical differences regarding preimplantation loss and implantation efficiency values of the rats treated with isolated and associated antiretroviral drugs. There was a significant increase in the postimplantation loss values (control group: 7.6%; drug groups variation: 20.2-26.7%, a decrease in the fetal viability values (control group: 92.4%, drug groups variation: 73.3-79.8%, and a decreasing number of fetuses per animal (control group: 14.7; drug groups variation: 11.1-12.7. There was a significant weight reduction of the female rats and of the offspring of animals treated with 3TC, AZT + 3TC and AZT + 3TC + NFV. CONCLUSION: with the administration of high antiretroviral doses, important fertility effects could be observed, which showed that less histotoxic antiretroviral drugs must be studied in order to warrant the safety of using these medicines in pregnant HIV-1 - infected women.

    Full Text Available BACKGROUND: Little is known about the variability of CD4 counts in the general population of sub-Saharan Africa countries affected by the HIV epidemic. We investigated factors associated with CD4 counts in a rural area in South Africa with high HIV prevalence and high antiretroviral treatment (ART coverage. METHODS: CD4 counts, health status, body mass index (BMI, demographic characteristics and HIV status were assessed in 4990 adult resident participants of a demographic surveillance in rural KwaZulu-Natal in South Africa; antiretroviral treatment duration was obtained from a linked clinical database. Multivariable regression analysis, overall and stratified by HIV status, was performed with CD4 count levels as outcome. RESULTS: Median CD4 counts were significantly higher in women than in men overall (714 vs. 630 cells/µl, p<0.0001, both in HIV-uninfected (833 vs. 683 cells/µl, p<0.0001 and HIV-infected adults (384.5 vs. 333 cells/µl, p<0.0001. In multivariable regression analysis, women had 19.4% (95% confidence interval (CI 16.1-22.9 higher CD4 counts than men, controlling for age, HIV status, urban/rural residence, household wealth, education, BMI, self-reported tuberculosis, high blood pressure, other chronic illnesses and sample processing delay. At ART initiation, HIV-infected adults had 21.7% (95% CI 14.6-28.2 lower CD4 counts than treatment-naive individuals; CD4 counts were estimated to increase by 9.2% (95% CI 6.2-12.4 per year of treatment. CONCLUSIONS: CD4 counts are primarily determined by sex in HIV-uninfected adults, and by sex, age and duration of antiretroviral treatment in HIV-infected adults. Lower CD4 counts at ART initiation in men could be a consequence of lower CD4 cell counts before HIV acquisition.

    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.

    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.

    Many variables have been studied pertaining to the block sprint start. Research suggests that the adoption of a medium block spacing is preferred, with front and rear knee angles in the set position approximating 90 and 130 degrees, respectively, with the hips held moderately high. The sprinter must be capable of developing a high force rate combined with a high maximum force, especially in the horizontal direction. This ability to create high force underlies other important indicators of starting performance such as minimum block clearance time, maximum block leaving velocity and maximum block leaving acceleration. Once the sprinter has projected him/herself from the blocks at a low angle (40 to 45 degrees) relative to the ground, the following 2 post-block steps should occur with the total body centre of gravity ahead of the contacting foot at foot strike to minimise potential horizontal braking forces.

    Full Text Available Background: Healthcare workers are often reluctant to start combination antiretroviral therapy (ART in patients receiving tuberculosis (TB treatment because of the fear of high pill burden, immune reconstitution inflammatory syndrome, and side-effects.Object: To quantify changes in adherence to tuberculosis treatment following ART initiation.Design: A prospective observational cohort study of ART-naïve individuals with baseline CD4 count between 50 cells/mm3 and 350 cells/mm3 at start of TB treatment at a primary care clinic in Johannesburg, South Africa. Adherence to TB treatment was measured by pill count,self-report, and electronic Medication Event Monitoring System (eMEMS before and after initiation of ART.Results: ART tended to negatively affect adherence to TB treatment, with an 8% – 10% decrease in the proportion of patients adherent according to pill count and an 18% – 22% decrease in the proportion of patients adherent according to eMEMS in the first month following ART initiation, independent of the cut-off used to define adherence (90%, 95% or 100%. Reasons for non-adherence were multi factorial, and employment was the only predictor for optimal adherence (adjusted odds ratio 4.11, 95% confidence interval 1.06–16.0.Conclusion: Adherence support in the period immediately following ART initiation could optimise treatment outcomes for people living with TB and HIV.

    Full Text Available A problem of highly active antiretroviral therapy (HAART in HIV patients is their adherence to treatment. The aim of this study was to compare the schemes adopted in the initial therapy of these treatments with their adherence, changes in HAART schemes and treatment costs. The study included patients over 16 years old, HIV positive, in treatment for more than 30 days. Adherence to HAART was calculated based on the withdrawal of the drug, which was related to the total treatment time. We evaluated how many patients changed HAART. The costs of each regimen were also estimated and related to the benefit of each treatment. 142 patients who were between 38 and 1,150 days of treatment were included (57.7% women. The schemes with lower costs, highest adherence and greater benefit were efavirenz with biovir and efavirenz with lamivudine and tenofovir. This study suggested the advantageous therapeutic regimens to start of treatment, both from the point of view of patients and the health system. This information can serve as a subsidy to clinicians in the decision of starting HAART.

    HIV-related eye disease can be classified as retinal HIV microangiopathy, opportunistic infections, neuro-ophthalmic manifestations and unusual malignancies. There is a 52-100% lifetime accumulative risk of HIV patients developing eye problems. Seventy-seven per cent of patients with ocular manifestations of HIV had CD4 counts 100 cells/μL for a minimum of three months. Despite HAART, patients with a CD4 count PORN), less commonly toxoplasmosis, pneumocystis and cryptococcus. Malignancies associated with HIV include Kaposi's sarcoma and conjunctival squamous cell carcinoma. Cranial nerve palsies, optic disc swelling and atrophy are characteristic neuro-ophthalmic features. They usually occur secondary to meningitis/encephalitis (from cryptococcus and tuberculosis). With the advent of HAART, new complications have developed in CMV retinitis: immune recovery uveitis (IRU) and cystoid macula oedema (CMO). Immune recovery uveitis occurs in 71% of patients if HAART is started before the induction of the anti-CMV treatment. However, this is reduced to 31% if HAART is started after the induction treatment. Molluscum contagiosum and Kaposi's sarcoma can spontaneously resolve on HAART. Highly active anti-retroviral therapy has reduced the frequencies of opportunistic infections and improved the remission duration in HIV patients. PMID:24756590

    Full Text Available Anecdotal data suggest that some South Africans living with HIV who receive disability grants from the state deliberately default on their antiretroviral medication in an attempt to lower their CD4 count to remain eligible for grants. No actual empirical data however exist to show that disability grants act as such perverse incentives and are a valid reason for non-adherence. This article examines some of the complexities of antiretroviral adherence in the context of a resource-constrained environment. The multitude of structural barriers, including sometimes difficult patient-doctor conversations about the renewal of disability grants, shape patients’ experiences of the clinic environment and influence their adherence to care.

    Nevirapine (11-cyclopropyl-5,11-dihydro-4-methyl-6H-dipyrido[3,2-b:2',3'e][1,4]diazepin-6-one) is an antiretroviral drug belonging to the class of the non-nucleoside inhibitors of the HIV-1 virus reverse transcriptase. As most of this kind of antiretroviral drugs, nevirapine displays a butterfly-like conformation which is preserved in complexes with the HIV-1 reverse transcriptase. In this work, we present a detailed vibrational spectroscopy investigation of nevirapine by using mid-infrared, near-infrared, and Raman spectroscopies. These data are supported by quantum mechanical calculations, which allow us to characterize completely the vibrational spectra of this compound. Based on these results, we discuss the correlation between the vibrational modes and the crystalline structure of the most stable form of nevirapine.

The chemical, biological, immune, virological, and toxicological properties of these formulations were compared using an established monocyte-derived macrophage scoring indicator system. Measurements of drug uptake, retention, release, and antiretroviral activity demonstrated differences amongst preparation methods. Interestingly, for drug cell targeting and antiretroviral responses the most significant difference among the particles was the drug itself. We posit that the choice of drug and formulation composition may ultimately affect clinical utility.Keywords: human immunodeficiency virus type one, nanotoxicology, monocyte-derived macrophage, nanoformulated antiretroviral therapy, manufacturing techniques

  20. Can Urine Lamivudine Be Used to Monitor Antiretroviral Treatment Adherence?

    Full Text Available Abstract Patient adherence to treatment is an important factor in the effectiveness of antiretroviral regimens. Adherence to treatment could be monitored by estimation of antiretroviral drugs in biological fluids. We aimed to obtain information on the quantity and duration of excretion of lamivudine in urine following oral administration of a single dose of 300 mg and to assess its suitability for adherence monitoring purposes. Spot urine samples were collected before dosing and at 4, 8, 12, 24, 28, 32, 48, 72, and 96 hours post dosing from 10 healthy subjects, and lamivudine was estimated by high-pressure liquid chromatography (HPLC. Lamivudine values were expressed as a ratio of urine creatinine. About 91% of the ingested drug was excreted by 24 hours, and the concentration thereafter in urine was very negligible. A lamivudine value of 0.035 mg/mg creatinine or less at 48 hours is suggestive of a missed dose in the last 24 hours. The study findings showed that estimation of urine lamivudine in spot specimens could be useful in monitoring patient adherence to antiretroviral treatment. However, this needs to be confirmed on a larger sample size and among patients on once-daily and twice-daily treatment regimens.

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

    HIV-positive patients may be effectively treated with highly active antiretroviral therapy and such a strategy is associated with striking immune recovery and viral load reduction to very low levels. Despite undeniable results, the central nervous system (CNS) is commonly affected during the course of HIV infection, with neurocognitive disorders being as prevalent as 20-50 % of treated subjects. This review discusses the pathophysiology of CNS infection by HIV and the barriers to efficacious control of such a mechanism, including the available data on compartmental drug penetration and on pharmacokinetic/pharmacodynamic relationships. In the reviewed articles, a high variability in drug transfer to the CNS is highlighted with several mechanisms as well as methodological issues potentially influencing the observed results. Nevirapine and zidovudine showed the highest cerebrospinal fluid (CSF) to plasma ratios, although target concentrations are currently unknown for the CNS. The use of the composite CSF concentration effectiveness score has been associated with better virological outcomes (lower HIV RNA) but has been inconsistently associated with neurocognitive outcomes. These findings support the CNS effectiveness of commonly used highly antiretroviral therapies. The use of antiretroviral drugs with increased CSF penetration and/or effectiveness in treating or preventing neurocognitive disorders however needs to be assessed in well-designed prospective studies.

    Full Text Available 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

    Full Text Available A cross-sectional study was conducted on HIV-infected adults being treated with antiretroviral drugs at a reference service in Southern Brazil. Participants answered a sociodemographic questionnaire and were tested by scales assessing sociocognitive variables. Adherence to treatment was assessed by a self-report inventory developed for the study. Clinical information was obtained from the patients' records. Significance tests were conducted using univariate logistic regressions followed by multivariate logistic regression analysis. A total of 195 patients participated in the study and 56.9% of them reported > or = 95% adherence on the previous two days. In univariate analysis, the odds of adherence increased with self-efficacy (a person's conviction that he/she can successfully execute the behavior required to produce a certain desired outcome in taking medications as prescribed (OR = 3.50, 95% CI 1.90-6.55, and decreased with perception of negative affect and physical concerns (OR = 0.71, 95% CI 0.53-0.95. The odds were lower for taking antiretroviral medications >4 times a day (OR = 0.44, 95% CI 0.20-0.94 and higher for patients with 8 years of schooling (OR = 2.28, 95% CI 1.12-4.66. In the multivariate analysis, self-efficacy (OR = 3.33, 95% CI 1.69-6.56 and taking medication >4 times a day (OR = 0.34, 95% CI 0.14-0.80 were independently associated with adherence. Self-efficacy was the most important predictor of adherence, followed by number of times antiretroviral medication was taken per day. Among sociodemographic and clinical variables, only the number of years of schooling was associated with adherence. Motivational interventions based on self-efficacy may be useful for increasing treatment adherence.

    Background In Côte d’Ivoire, tuberculosis (TB) is a common cause of death among HIV-infected antiretroviral therapy (ART) enrollees. Ivorian guidelines recommend screening for TB and initiation of TB treatment before ART initiation. Compliance with these guidelines can help reduce TB-related mortality during ART and possibly nosocomial TB transmission. Methods and Findings In a retrospective cohort study among 3,682 randomly selected adults (≥15 years old) starting ART during 2004–2007 at 34 randomly selected facilities, documentation of TB screening completion, prevalence of active TB at ART initiation, and incidence of TB during ART were evaluated. At ART initiation, median age was 36 years, 67% were female, and median CD4 count was 135 cells/μL. Among all 3,682 enrollees, 73 (2%) were on TB treatment at the time of referral to the ART facility. Among the 3,609 not on TB treatment, 1,263 (36%) were documented to receive some TB screening before ART initiation; 21% were screened for cough, 21% for weight loss, 18% for fever, 18% for TB contacts, and 12% for night sweats. Among the 1,263 screened, 111 (11%) were diagnosed with TB and started TB treatment before ART. No associations between patient characteristics and probability of being screened were noted. However, documentation of TB screening completion before ART varied widely by ART facility from 0–100%. TB incidence during ART was 3.0 per 100 person-years but varied widely by ART facility from 0/100 person-year to 13.1/100 person-years. Conclusions Screening for TB before ART initiation was poorly documented. Facility-level variations in TB screening documentation suggest facility-level factors, such as investment in training programs, might determine documentation practices. Targeting under-performing ART facilities with improvement activities is needed. Variations among facilities in TB incidence warrant further research. These incidence variations could reflect differences between facilities in

    The first major particle physics summer conference has just started this week in Grenoble. After the Quark-Matter conference, the Europhysics Conference on High-Energy Physics marks the start of a promising harvest for the LHC experiments.   For the first time, the collaborations will be presenting their latest results based on all luminosity taken until end of June, which will provide more precise measurements in many areas. Thanks to the excellent performance of the LHC, the experiments have already accumulated a substantial quantity of data allowing them to push back the known limits and refine measurements in many fields ranging from b physics to the search for the Higgs boson and for dark matter. At the time of writing, the LHC collaborations are about to present these new results in an energy range which has never previously been explored. I have congratulated all the teams involved in getting the LHC into operation in record time with great efficiency. Today I would like to acknowledge the...

    The HIV epidemic in Vietnam is concentrated, with high prevalence estimates among injection drug users and commercial sex workers. Socio-demographics, substance use and clinical correlates of antiretroviral therapy non-adherence were studied in 100 HIV-1 infected drug users receiving antiretroviral therapy for at least 6 months in Hanoi, Vietnam. All study participants were men with a mean age of 29.9 ± 4.9 years. The median duration on antiretroviral therapy was 16.2 ± 12.7 months; 83% reported 'very good' or 'perfect' adherence in the past 30 days on a subjective one-item Likert scale at time of study enrollment; 48% of participants reported drug use within the previous 6 months, with 22% reporting current drug use. Injection drug use with or without non-injection drug use in the past 6 months (95% C.I. 2.19, 1.30-3.69) and years on antiretroviral therapy (95% C.I. 1.43, 1.14-1.78) were correlated with suboptimal adherence. These findings support Vietnam's ongoing scale-up of harm reduction programmes for injection drug users and their integration with antiretroviral therapy delivery. Moreover, results highlight the need to identify and implement new ways to support high levels of antiretroviral therapy adherence as duration on antiretroviral therapy increases.

    SummaryHighly active antiretroviral therapy has decreased the morbidity and mortality related to HIV infection, including oral opportunistic infections. This paper offers an analysis of the scientific literature on the epidemiological aspects of oral candidiasis in HIV-positive children in the combination antiretroviral therapy era. An electronic databases search was made covering the highly active antiretroviral therapy era (1998 onwards). The terms used were oral lesions, oral candidiasis and their combination with highly active antiretroviral therapy and HIV/AIDS children. The following data were collected from each paper: year and country in which the investigation was conducted, antiretroviral treatment, oral candidiasis prevalence and diagnostic parameters (clinical or microbiological). Prevalence of oral candidiasis varied from 2.9% in American HIV-positive children undergoing highly active antiretroviral therapy to 88% in Chilean HIV-positive children without antiretroviral therapy. With respect to geographical location and antiretroviral treatment, higher oral candidiasis prevalence in HIV-positive children on combination antiretroviral therapy/antiretroviral therapy was reported in African children (79.1%) followed by 45.9% reported in Hindu children. In HIV-positive Chilean children on no antiretroviral therapy, high oral candidiasis prevalence was reported (88%) followed by Nigerian children (80%). Oral candidiasis is still frequent in HIV-positive children in the highly active antiretroviral therapy era irrespective of geographical location, race and use of antiretroviral therapy.

  15. AIDS-associated diarrhea and wasting in northeast Brazil is associated with subtherapeutic plasma levels of antiretroviral medications and with both bovine and human subtypes of Cryptosporidium parvum

    Full Text Available Advanced HIV infection is frequently complicated by diarrhea, disruption of bowel structure and function, and malnutrition. Resulting malabsorption of or pharmacokinetic changes in antiretroviral agents might lead to subtherapeutic drug dosing and treatment failure in individual patients, and could require dose adjustment and/or dietary supplements during periods of diarrheal illness. We determined the plasma levels of antiretroviral medications in patients that had already been started on medication by their physicians in an urban infectious diseases hospital in northeast Brazil. We also obtained blood samples from patients hospitalized for diarrhea or AIDS-associated wasting, and we found reduced stavudine and didanosine levels in comparison with outpatients without diarrhea or wasting who had been treated at the same hospital clinic. There was a predominance of the protozoal pathogens Cryptosporidium and Isospora belli, typical opportunistic pathogens of AIDS-infected humans, in the stool samples of inpatients with diarrhea. We conclude that severe diarrhea and wasting in this population is associated with both protozoal pathogens and subtherapeutic levels of antiretroviral medications.

Estudo de corte transversal com pacientes de dois serviços públicos de referência (n = 310 em Belo Horizonte, Minas Gerais, Brasil. Atraso no início da TARV foi definido como ter contagem de linfócitos T CD4+ The main objective was to assess the proportion of delayed initiation of antiretroviral therapy (ART and associated factors. This was a cross-sectional study of 310 patients enrolled in two public health centers in Belo Horizonte, Minas Gerais State, Brazil. Delayed ART initiation was defined as starting treatment with a CD4 count lower than 200 cells/mm³ or clinical symptoms of severe immunodepression at the time of first antiretroviral prescription. The majority of participants were males (63.9%, had no health insurance (76.1%, and started ART less than 120 days after the first medical visit (75.2%. The proportion of delayed ART initiation was 68.4%. Unemployment, referral by a health professional for HIV testing, fewer than two medical visits in the six months prior to ART initiation, and time between first medical visit and ART initiation less than 120 days were independently associated with the outcome. Our results suggest that every patient 13 to 64 years of age should be offered HIV testing, which could increase the rate of early HIV diagnosis, and thus patients that tested positive could benefit from timely follow-up and antiretroviral therapy.

    Full Text Available BACKGROUND: HIV/AIDS affects all sectors of the population and the defence forces are not exempt. A national survey was conducted in all public and private sectors in Malawi that provide antiretroviral therapy (ART to determine the uptake of ART by army personnel, their outcomes while on treatment, and the impact of ART on mortality in the Malawi Defence Force. METHODOLOGY/PRINCIPAL FINDINGS: A retrospective cohort analysis was carried out, collecting data on access and retention on treatment from all 103 public and 38 private sector ART clinics in Malawi, using standardised patient master cards and clinic registers. Observations were censored on December 31(st 2006. Independent data on mortality trends in army personnel from all causes between 2002 and 2006 were available from army records. By December 31(st 2006, there were 85,168 patients ever started on ART in both public and private sectors, of whom 547 (0.7% were army personnel. Of these, 22% started ART in WHO clinical stage 1 or 2 with a CD4-lymphocyte count of started in stage 3 or 4. Treatment outcomes of army personnel by December 31(st 2006 were:-365 (67% alive and on ART at their registration facility, 98 (18% transferred out to another facility, 71 (13% dead, 9 (2% lost to follow-up, and 4 (<1% stopped treatment. The probability of being alive on ART at 6-, 12- and 18-months was 89.8%, 83.4% and 78.8% respectively. All-cause mortality in army personnel declined dramatically over the five year period from 2002-2006. CONCLUSION/SIGNIFICANCE: There has been a good access of army personnel to ART during the last five years with excellent outcomes, and this should serve as an example for other defence forces and large companies in the region.

    Full Text Available Background. Regular clinic attendance for antiretroviral (ARV drug refills is important for successful clinical outcomes in HIV management. Methods. Clinic attendance for ARV drug refills and medication adherence using a clinic-based pill count in 392 adult patients receiving antiretroviral therapy (ART in a district hospital in Uganda were prospectively monitored over a 28-week period. Results. Of the 2267 total scheduled clinic visits, 40 (1.8% were missed visits. Among the 392 clients, 361 (92% attended all appointments for their refills (regular attendance. Clinic attendance for refills was statistically significantly associated with medication adherence with regular attendant clients having about fourfold greater odds of achieving optimal (≥95% medication adherence [odds ratio (OR=3.89, 95% CI: 1.48 to 10.25, exact P=.013]. In multivariate analysis, clients in age category 35 years and below were less likely to achieve regular clinic attendance. Conclusion. Monitoring of clinic attendance may be an objective and effective measure and could be a useful adjunct to an adherence measure such as pill counting in resource-constrained settings. Where human resource constraints do not allow pill counts or other time-consuming measures, then monitoring clinic attendance and acting on missed appointments may be an effective proxy measure.

    Combination antiretroviral therapy has been shown to reduce HIV transmission and incident infections. In recent years, Malawi has significantly increased the number of individuals on combination antiretroviral drugs through more inclusive treatment policies. Using a retrospective observational cohort design, records with HIV test results were reviewed for pregnant women attending a referral hospital in Malawi over a 5-year period, with viral load measurements recorded. HIV prevalence over time was determined, and results correlated with population viral load. A total of 11 052 women were included in this analysis, with 440 (4.1%) HIV infections identified. HIV prevalence rates in pregnant women in Malawi halved from 6.4% to 3.0% over 5 years. Mean viral loads of adult patients decreased from 120 000 copies/mL to less than 20 000 copies/mL. Results suggest that community viral load has an effect on HIV incidence rates in the population, which in turn correlates with reduced HIV prevalence rates in pregnant women.

    Although Structured Treatment Interruptions (STI) are currently not considered an alternative strategy for antiretroviral treatment, their true benefits and limitations have not been fully established. Some studies suggest the possibility of improving the quality of life of patients with this strategy; however, the information that has been obtained corresponds mostly to studies conducted in adults, with a lack of knowledge about its impact on children. Furthermore, mutations associated with antiretroviral resistance could be selected due to sub-therapeutic levels of HAART at each interruption period. Genotyping methods to determine the resistance profiles of the infecting viruses have become increasingly important for the management of patients under STI, thus low-abundance antiretroviral drug-resistant mutations (DRM's) at levels under limit of detection of conventional genotyping (drugs. The results could suggest that the evaluated STI program is virologically safe, but strict and carefully planned studies, with greater numbers of patients and interruption/restart cycles, are still needed to evaluate the selection of DRM's during STI.

    HIV-1-associated Guillan-Barre syndrome (hGBS) is an ascendant progressive polyradiculoneuropathy described throughout the course of the viral disease, mainly associated with the acute retroviral syndrome. HGBS is occasionally described in severely immunocompromised subjects in the context of the immune reconstitution inflammatory syndrome. The case described occurred soon after the start of a combined antiretroviral treatment in an HIV-1 infected patient with ulcerative colitis in the absence of severe immunosuppression. This manifestation may be interpreted as an uncommon appearance of an immune reconstitution syndrome in the presence of a predisposing autoimmune pathology.

    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/mm(3) and HIV-1 RNA level ≤400 copies/ml (group 1), CD4 T cell count ≥350 cells/mm(3) and HIV-1 RNA level >400 copies/ml (group 2), CD4 T cell count 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.

In this work, we analyzed the protease and reverse transcriptase regions of the pol gene by ultra-deep sequencing in pediatric patients under STI with the aim of determining the presence of high- and low-abundance DRM's in the viral rebounds generated by the STI. High-abundance mutations in protease and high- and low-abundance mutations in reverse transcriptase were detected but no one of these are directly associated with resistance to antiretroviral drugs. The results could suggest that the evaluated STI program is virologically safe, but strict and carefully planned studies, with greater numbers of patients and interruption/restart cycles, are still needed to evaluate the selection of DRM's during STI.

    Although Structured Treatment Interruptions (STI) are currently not considered an alternative strategy for antiretroviral treatment, their true benefits and limitations have not been fully established. Some studies suggest the possibility of improving the quality of life of patients with this strategy; however, the information that has been obtained corresponds mostly to studies conducted in adults, with a lack of knowledge about its impact on children. Furthermore, mutations associated with antiretroviral resistance could be selected due to sub-therapeutic levels of HAART at each interruption period. Genotyping methods to determine the resistance profiles of the infecting viruses have become increasingly important for the management of patients under STI, thus low-abundance antiretroviral drug-resistant mutations (DRM’s) at levels under limit of detection of conventional genotyping (<20% of quasispecies) could increase the risk of virologic failure. In this work, we analyzed the protease and reverse transcriptase regions of the pol gene by ultra-deep sequencing in pediatric patients under STI with the aim of determining the presence of high- and low-abundance DRM’s in the viral rebounds generated by the STI. High-abundance mutations in protease and high- and low-abundance mutations in reverse transcriptase were detected but no one of these are directly associated with resistance to antiretroviral drugs. The results could suggest that the evaluated STI program is virologically safe, but strict and carefully planned studies, with greater numbers of patients and interruption/restart cycles, are still needed to evaluate the selection of DRM’s during STI.

    Full Text Available Introduction: Lesotho was among the first countries to adopt decentralization of care from hospitals to nurse-led health centres (HCs to scale up the provision of antiretroviral therapy (ART. We compared outcomes between patients who started ART at HCs and hospitals in two rural catchment areas in Lesotho. Methods: The two catchment areas comprise two hospitals and 12 HCs. Patients ≥16 years starting ART at a hospital or HC between 2008 and 2011 were included. Loss to follow-up (LTFU was defined as not returning to the facility for ≥180 days after the last visit, no follow-up (no FUP as not returning after starting ART, and retention in care as alive and on ART at the facility. The data were analysed using logistic regression, competing risk regression and Kaplan-Meier methods. Multivariable analyses were adjusted for sex, age, CD4 cell count, World Health Organization stage, catchment area and type of ART. All analyses were stratified by gender. Results: Of 3747 patients, 2042 (54.5% started ART at HCs. Both women and men at hospitals had more advanced clinical and immunological stages of disease than those at HCs. Over 5445 patient-years, 420 died and 475 were LTFU. Kaplan-Meier estimates for three-year retention were 68.7 and 69.7% at HCs and hospitals, respectively, among women (p=0.81 and 68.8% at HCs versus 54.7% at hospitals among men (p<0.001. These findings persisted in adjusted analyses, with similar retention at HCs and hospitals among women (odds ratio (OR: 0.89, 95% confidence interval (CI: 0.73–1.09 and higher retention at HCs among men (OR: 1.53, 95% CI: 1.20–1.96. The latter result was mainly driven by a lower proportion of patients LTFU at HCs (OR: 0.68, 95% CI: 0.51–0.93. Conclusions: In rural Lesotho, overall retention in care did not differ significantly between nurse-led HCs and hospitals. However, men seemed to benefit most from starting ART at HCs, as they were more likely to remain in care in these facilities

    2016-01-01

    Following the characterization of a human betaretrovirus in patients with primary biliary cirrhosis (PBC), pilot studies using antiretroviral therapy have been conducted as proof of principal to establish a link of virus with disease and with the eventual aim to find better adjunct therapies for patients unresponsive to ursodeoxycholic acid. In the first open label pilot study, the reverse transcriptase inhibitor lamivudine had little demonstrable biochemical or histological effect after 1 year. Whereas, lamivudine in combination with zidovudine was associated with a significant reduction in alkaline phosphatase as well as improvement in necroinflammatory score, cholangitis and ductopenia over a 12 mo period. A double blind, multi-center randomized controlled trial using lamivudine with zidovudine for 6 mo confirmed a significant reduction in alkaline phosphatase, ALT and AST in patients on antiviral therapy. However, none of the patients achieved the stringent endpoint criteria for normalization of alkaline phosphatase. Furthermore, some patients developed biochemical rebound consistent with drug resistance. A major fault of these studies has been the inability to measure the viral load in peripheral blood and therefore, provide a direct correlation between improvement of hepatic biochemistry and reduction in viral load. Nevertheless, viral mutants to lamivudine with zidovudine were later characterized in the NOD.c3c4 mouse model of PBC that has been used to test other antiretroviral regimens to betaretrovirus. The combination of tenofovir and emtricitabine reverse transcriptase inhibitors and the HIV protease inhibitor, lopinavir were found to abrogate cholangitis in the NOD.c3c4 mouse model and the same regimen normalized the liver tests in a PBC patient with HIV and human betaretrovirus infection. This combination antiretroviral therapy has now been used in a double blind randomized controlled crossover study for patients with PBC followed by an open label

    Full Text Available Abstract Background Combination antiretroviral (AR therapy continues to be the mainstay for HIV treatment. However, antiretroviral drug nonadherence can lead to the development of resistance and treatment failure. We have designed nanoparticles (NP that contain three AR drugs and characterized the size, shape, and surface charge. Additionally, we investigated the in vitro release of the AR drugs from the NP using peripheral blood mononuclear cells (PBMCs. Methods Poly-(lactic-co-glycolic acid (PLGA nanoparticles (NPs containing ritonavir (RTV, lopinavir (LPV, and efavirenz (EFV were fabricated using multiple emulsion-solvent evaporation procedure. The nanoparticles were characterized by electron microscopy and zeta potential for size, shape, and charge. The intracellular concentration of AR drugs was determined over 28 days from NPs incubated with PBMCs. Macrophages were imaged by fluorescent microscopy and flow cytometry after incubation with fluorescent NPs. Finally, macrophage cytotoxicity was determined by MTT assay. Results Nanoparticle size averaged 262 ± 83.9 nm and zeta potential -11.4 ± 2.4. AR loading averaged 4% (w/v. Antiretroviral drug levels were determined in PBMCs after 100 μg of NP in 75 μL PBS was added to media. Intracellular peak AR levels from NPs (day 4 were RTV 2.5 ± 1.1; LPV 4.1 ± 2.0; and EFV 10.6 ± 2.7 μg and continued until day 28 (all AR ≥ 0.9 μg. Free drugs (25 μg of each drug in 25 μL ethanol added to PBMCs served as control were eliminated by 2 days. Fluorescence microscopy and flow cytometry demonstrated phagocytosis of NP into monocytes-derived macrophages (MDMs. Cellular MTT assay performed on MDMs demonstrated that NPs are not significantly cytotoxic. Conclusion These results demonstrated AR NPs could be fabricated containing three antiretroviral drugs (RTV, LPV, EFV. Sustained release of AR from PLGA NP show high drug levels in PBMCs until day 28 without cytotoxicity.

    Full Text Available Abstract Background Rhodococcus equi (R.equi is an acid fast, GRAM + coccobacillus, which is widespread in the soil and causes pulmonary and extrapulmonary infections in immunocompromised people. In the context of HIV infection, R.equi infection (rhodococcosis is regarded as an opportunistic disease, and its outcome is influenced by highly active antiretroviral therapy (HAART. Case presentation We report two cases of HIV-related rhodococcosis that disseminated despite suppressive HAART and anti-rhodococcal treatment; in both cases there was no immunological recovery, with CD4+ cells count below 200/μL. In the first case, pulmonary rhodococcosis presented 6 months after initiation of HAART, and was followed by an extracerebral intracranial and a cerebral rhodococcal abscess 1 and 8 months, respectively, after onset of pulmonary infection. The second case was characterized by a protracted course with spread of infection to various organs, including subcutaneous tissue, skin, colon and other intra-abdominal tissues, and central nervous system; the spread started 4 years after clinical resolution of a first pulmonary manifestation and progressed over a period of 2 years. Conclusions Our report highlights the importance of an effective immune recovery, despite fully suppressive HAART, along with anti-rhodococcal therapy, in order to clear rhodococcal infection.

    High level adherence to antiretroviral therapy (ART) is required to achieve and maintain suppression of HIV replication. Although directly observed therapy (DOT) has been suggested as an intervention to improve adherence, there is a paucity of data describing the attitudes and beliefs regarding DOT for ART among HIV-infected individuals. This study was designed to evaluate the acceptability and psychometric properties of a survey instrument for use in assessing barriers and facilitators of adherence to ART DOT in prison. From July 1, 1999 to April 1, 2000, we piloted an interviewer-administered questionnaire to assess health beliefs and attitudes regarding HIV treatment among 65 HIV-infected prison inmates receiving one or more of their antiretrovirals via directly observed therapy (DOT). The first 24 participants were administered the questionnaire to determine the feasibility of surveying prisoners in a correctional setting. There were no adherence data collected on these participants. The remaining 41 participants had their adherence measured in addition to receiving the questionnaire. Thirty-one were included in the final analysis because 10 did not complete the study. Multiple antiretroviral adherence measures (electronic device medication monitoring [eDEM] caps, medication administration records [MARs], and pill counts) were assessed among a subset of the participants (n = 31) and correlated to the instrument response items. The median internal consistency reliability coefficient for the multi-item scales was 0.79. The strongest correlation between inmates' beliefs and their adherence was between "positive beliefs about protease inhibitors" and the MAR adherence measure (r = 0.72; p < 0.001). This study provides preliminary support for the psychometric properties of the survey in this correctional setting. PMID:16789854

    Unlike other natural hazards, earthquakes strike suddenly and without warning. Consequently, prevention is the best we can do to ensure safety. In spite of the large and medium earthquakes, some of them tsunamigenic, that affected Portugal in the past, the Portuguese society is little aware of the seismic risk and has not developed an adequate culture of prevention. This is most probably due to the long time interval between destructive earthquakes. Earthquakes can be a real danger to societies, damaging human-made structures and endangering human lives. Earthquakes can trigger additional emergencies, and individuals should also be prepared to contend with it. By planning and practicing what to do if an earthquake strikes, children and their family can learn to react correctly and automatically when the shaking begins. Risks can then be dramatically lessened if the population is educated on how to react before, during and after an earthquake. Children's knowledge is ever growing. They have a fundamental role in changing societies. By educating the children of today we are forming better adults of tomorrow. We are simultaneously passing this knowledge to their caregivers and families. Through demonstrating how fundamental it is to be conscious of those issues, not only will the children will be informed, but also their relatives will be aware of such risks. We use this approach to explain children how to assess risk in a broader sense. We teach them other preventive measures, namely those related with electricity, gas and the danger on non-potable water, essential topics on "what to do before an earthquake" but also on the daily routines. This presentation will highlight the importance of encouraging a culture of prevention. This project funded by the Portuguese "Ciência Viva" program, and is conducted by science high-school students, teachers and the parents association.

    Primary HIV-1 infection causes extensive immune activation, during which CD4+ T cell activation supports massive HIV-1 production. We tested the safety and the immune-modulating effects of combining cyclosporin A (CsA) treatment with highly active antiretroviral therapy (HAART) during primary HIV-1 infection. Nine adults with primary HIV-1 infection were treated with CsA along with HAART. At week 8, all patients discontinued CsA but maintained HAART. Viral replication was suppressed to a comparable extent in the CsA + HAART cohort and in 29 control patients whose primary infection was treated with HAART alone. CsA restored normal CD4+ T cell levels, both in terms of percentage and absolute numbers. The increase in CD4+ T cells was apparent within a week and persisted throughout the study period. CsA was not detrimental to virus-specific CD8+ or CD4+ T cell responses. At week 48, the proportion of IFN-γ–secreting CD4+ and CD4+CCR7– T cells was significantly higher in the CsA + HAART cohort than in the HAART-alone cohort. In conclusion, rapid shutdown of T cell activation in the early phases of primary HIV-1 infection can have long-term beneficial effects and establish a more favorable immunologic set-point. Appropriate, immune-based therapeutic interventions may represent a valuable complement to HAART for treating HIV infection. PMID:11877476

    Monitoring patient adherence to HIV antiretroviral therapy (ART) by patient survey is inherently error prone, justifying a need for objective, biological measures affordable in low-resource settings where HIV/AIDS epidemic is highest. In preliminary studies conducted in Ethiopia and South Africa, we observed loss of cysteine cathepsin activity in peripheral blood mononuclear cells of HIV-positive patients on ART. We optimized a rapid protocol for multiplex cathepsin zymography to quantify cysteine cathepsins, and prospectively enrolled 350 HIV-positive, ART-naïve adults attending the Themba Lethu Clinic, Johannesburg, South Africa, to test if suppressed cathepsin activity could be a biomarker of ART adherence (103 patients were included in final analysis). Poor adherence was defined as detectable viral load (>400 copies/ml) or simplified medication adherence questionnaire, 4-6 months after ART initiation. 86 % of patients with undetectable viral loads after 6 months were cathepsin negative, and cathepsin-positive patients were twice as likely to have detectable viral loads (RR 2.32 95 % CI 1.26-4.29). Together, this demonstrates proof of concept that multiplex cathepsin zymography may be an inexpensive, objective method to monitor patient adherence to ART. Low cost of this electrophoresis-based assay makes it a prime candidate for implementation in resource-limited settings. PMID:26589706

    Full Text Available Sclerosing colangitis (SC due to cytomegalovirus (CMV is very rare. It has been described mainly in immunocompromised patients. Currently, in HIV infected patients it is exceptional. The most of cases belong to pre-highly active antiretroviral therapy (pre-HAART and those cases were in stage AIDS with less than 100 CD4/μl. The most frequently involved pathogen in pre-HAART period was Cryptosporidium parvum (30-57% and CMV (10-30%; in late HAART period this information are unaware. CMV has been implicated as a possible etiological agent in primary SC partly because of the ability to cause liver damage and its relationship with smooth muscle antibodies. The most effective treatment for SC was the combination of antiretroviral therapy and endoscopic retrograde cholangiopancreatography with sphincterotomy and stent placement. Following, we present the first case of late HAART period which describes a SC extrahepatic without papillary stenosis with CMV as the only cause and clinical presentation of HIV infection in a woman with 177 CD4/μl.

    Lopinavir/ritonavir (LPV/r) was approved for use in the treatment of human immunodeficiency virus (HIV) infection in 2001 and is the protease inhibitor that has been most widely studied in clinical trials. Despite the time interval since its approval, all the evidence accumulated in the last 14 years indicates that LPV/r continues to occupy an important position among antiretroviral drugs. Firstly, LPV/r plus 2 nucleoside/nucleotide analogs is still considered a good option for initial antiretroviral therapy (ART). Secondly, numerous studies have evaluated the efficacy and safety of new initial ART strategies based on LPV/r in dual therapy. The results obtained suggest that LPV/r plus lamivudine (3TC) or raltegravir can be as effective in initial ART as standard triple therapy and justify their consideration as alternative regimens in this scenario. Thirdly, LPV/r is a pioneer drug, as well as being the agent with the largest amount of evidence from clinical trials on simplification to monotherapy (LPV/r) or dual therapy (LPV/r + 3TC). Lastly, LPV/r is highly useful is special situations. It has a low risk of liver toxicity in patients with chronic liver disease, its use is preferred in the treatment of patients with HIV-2, and it is safe and effective in preventing vertical HIV transmission.

    2014-07-01

    Oral antiretroviral preexposure prophylaxis (PrEP) has been shown to decrease human immunodeficiency virus (HIV) incidence in studies of men who have sex with men, heterosexual men and women, and injecting drug users. One study of pericoital tenofovir gel demonstrated that it reduced HIV incidence in South African women. However, other studies of African women failed to demonstrate protection with either oral tenofovir or tenofovir-emtricitabine, or daily tenofovir gel. The magnitude of PrEP protection appears to be highly correlated with medication adherence. New studies are evaluating whether different antiretrovirals, including dapivirine, rilpivirine, maraviroc, and new integrase inhibitors. Different formulations are also being evaluated, including gels, films, vaginal rings, and injectable medication. Although PrEP efficacy has been demonstrated, and several normative bodies (eg, the US Food and Drug Administration) have approved PrEP for clinical use, uptake has been slow. Reasons may include lack of sufficient provider and consumer education, residual concerns about costs, potential long-term toxicities, and behavioral disinhibition. Additional work is under way to determine how to best educate consumers and providers about optimal adherence and to use PrEP in conjunction with risk mitigation. PMID:24926034

    2012-01-01

    Full Text Available The present paper describes possible connections between antiretroviral therapies (ARTs used to treat human immunodeficiency virus (HIV infection and adverse drug reactions (ADRs encountered predominantly in the liver, including hypersensitivity syndrome reactions, as well as throughout the gastrointestinal system, including the pancreas. Highly active antiretroviral therapy (HAART has a positive influence on the quality of life and longevity in HIV patients, substantially reducing morbidity and mortality in this population. However, HAART produces a spectrum of ADRs. Alcohol consumption can interact with HAART as well as other pharmaceutical agents used for the prevention of opportunistic infections such as pneumonia and tuberculosis. Other coinfections that occur in HIV, such as hepatitis viruses B or C, cytomegalovirus, or herpes simplex virus, further complicate the etiology of HAART-induced ADRs. The aspect of liver pathology including liver structure and function has received little attention and deserves further evaluation. The materials used provide a data-supported approach. They are based on systematic review and analysis of recently published world literature (MedLine search and the experience of the authors in the specified topic. We conclude that therapeutic and drug monitoring of ART, using laboratory identification of phenotypic susceptibilities, drug interactions with other medications, drug interactions with herbal medicines, and alcohol intake might enable a safer use of this medication.

    Full Text Available A novel method for predicting maximum recommended therapeutic dose (MRTD is presented using quantitative structure property relationships (QSPRs and artificial neural networks (ANNs. MRTD data of 31 structurally diverse Antiretroviral drugs (ARVs were collected from FDA MRTD Database or package inserts. Molecular property descriptors of each compound, that is, molecular mass, aqueous solubility, lipophilicity, biotransformation half life, oxidation half life, and biodegradation probability were calculated from their SMILES codes. A training set (=23 was used to construct multiple linear regression and back propagation neural network models. The models were validated using an external test set (=8 which demonstrated that MRTD values may be predicted with reasonable accuracy. Model predictability was described by root mean squared errors (RMSEs, Kendall's correlation coefficients (tau, P-values, and Bland Altman plots for method comparisons. MRTD was predicted by a 6-3-1 neural network model (RMSE=13.67, tau=0.643, =0.035 more accurately than by the multiple linear regression (RMSE=27.27, tau=0.714, =0.019 model. Both models illustrated a moderate correlation between aqueous solubility of antiretroviral drugs and maximum therapeutic dose. MRTD prediction may assist in the design of safer, more effective treatments for HIV infection.

Many reports from African ART programmes make little mention of patients who are transferred out to another facility, yet Malawi's national figures show a transfer out of 9%. There is no published information about what happens to patients who transfer-out, but this is important because if they transfer-in and stay alive in these other facilities then national retention figures will be better than previously reported. METHODOLOGY/PRINCIPAL FINDINGS: Of all patients started on ART over a three year period in Mzuzu Central Hospital, North Region, Malawi, those who transferred out were identified from the ART register and master cards. Clinic staff attempted to trace these patients to determine whether they had transferred in to a new ART facility and their outcome status. There were 805 patients (19% of the total cohort who transferred out, of whom 737 (92% were traced as having transferred in to a new ART facility, with a median time of 1.3 months between transferring-out and transferring-in. Survival probability was superior and deaths were lower in the transfer-out patients compared with those who did not transfer. CONCLUSION/SIGNIFICANCE: In Mzuzu Central Hospital, patients who transfer-out constitute a large proportion of patients not retained on ART at their original clinic of registration. Good documentation of transfer-outs and transfer-ins are needed to keep track of national outcomes. Furthermore, the current practice of regarding transfer-outs as being double counted in national cohorts and subtracting this number from the total national registrations to get the number of new patients started on ART is correct.

    Background Early mortality in people initiating antiretroviral treatment (ART) in Africa remains high. Empiric TB treatment strategies aim to reduce early mortality by initiating TB treatment in individuals without clinical suspicion of TB who are at high-risk of death from undiagnosed TB. Methods Using data from 16,913 individuals starting ART under programmatic conditions, we simulated the impact of three empiric treatment strategies on mortality and incident TB: two randomized clinical trials (REMEMBER and PrOMPT) and a pragmatic approach. The main analysis assumed that 50% of early deaths and 100% of incident TB is averted in those eligible and ignored outcomes in those lost to follow up. Results The increase in individuals eligible for TB treatment under empirical TB treatment strategies ranged from 4.4% to 31.4% as compared to those started on clinical or mycobacteriological grounds. The proportion of deaths averted by empiric treatment strategies ranged from 5.5% to 25.4%. The proportion of incident TB cases averted ranged from 10.9% to 57.3%. The proportion receiving any TB treatment during the first six months of ART increased from the observed 24.0% to an estimated 27.5%, 40.4% and 51.3% under the PrOMPT, REMEMBER and pragmatic approach, respectively. Conclusion The impact of empiric TB treatment strategies depends greatly on the eligibility criteria chosen. The additional strain placed on TB treatment facilities and the relatively limited impact of some empirical TB strategies raise the question whether the benefits will outweigh the risks at population level.

    The prospects for expanded access to antiretroviral therapy (ART) in resource-poor settings have greatly improved as a result of global and national efforts to reduce the cost of antiretroviral drugs (ARV), growing availability of cheaper generics, and increased financing available from the Global Funds like Medicines Sans Frontieres. Indian health set-up provides drugs free-of-cost to HIV infected patients through government network and also through open-market to those who intend to have personalized care. Post-2005, implementation of WTO agreement on TRIPS is expected to have a significant impact on pricing and availability of generic ARV. The study has been planned to explore the trends and gaps in availability & accessibility of ARV in India. The trends in per-patient-per-year (PPPY) cost of individual ARV and treatment regimes were also explored. The epidemiological data demonstrated stabilization of the epidemic in India. Most ARV are available in India by the generic manufacturers with a median drug lag period of 2.05 years (Range 0.75-6.51 years). There is a significant price difference in drugs available from generic and originator companies. Prices for patented and generic ARV in India reflect price negotiations that have taken place since the introduction of drugs in the country, still most of the ARVs are available at a much higher cost in the market [median 2.6 times (range 1-7)]. The per-patient per year (PPPY) cost of providing first-line regime in 2008 has decreased 2.75 times from that in 2003. The analysis shows the stabilization of prices of all drugs after 2006. HIV spending in India has seen a growth of 26 percent and 28 percent in 2005-06 and 2006-07 respectively. Still, the expected expenditure to cover the whole patient population needing therapy is considerably higher than the actual expenditure incurred for providing ARV. Despite the price reductions and availability of ARV at a lower cost through agencies like MSF, there is a large gap

    Full Text Available Theory of attachment primarily described early relationships between a child and his caretakers. In the last twenty years there is a growing interest in adult attachment research. Theories and research findings of adult attachment stem from two different methodological approaches. The first approach measures adult attachment through Adult Attachment Interview (AAI; Main, 1991 where the attachment is assessed through the narratives of adult people of their early child experiences with their primary caretakers. The second approach measures adult attachment with the help of self-evaluative questionnaires, developed by (a Hazan and Shaver (1987 who started this approach in the field of personality and social psychology, and (b Bartholomew and Horowitz (1991. Research shows that there is significant correlation between early and adult attachment style. Attachment styles are passed from generation to generation. Basic adult attachment styles are: securely attached, preoccupied, fearful-avoidant, dismissing-avoidant and disorganized. Previous research using Barholomew and Horowitz (1991 Relationship Questionnaire on 176 Slovenian students showed that 48% students are securely attached, 29% are fearful-avoidant, 10% are dismissing-avoidant, and 13% have preoccupied attachment style. Theory of attachment is very useful for understanding the behavior and subjective experiences of children and adults. It is applicable to different contexts (psychotherapy, counseling, education .... The paper proposes further research focused on integration of adult attachment styles and types of object relations measured by Test of object relations (Žvelc, 1998 and Pictorial test of Separation and Individuation (Žvelc, 2003.

    Full Text Available Introduction: There is little information on adherence to antiretroviral therapy (ART in the Eastern European region. This prospective study evaluated multiple measures of adherence and their association with viral suppression among HIV patients in Georgia. Methods: A prospective cohort study enrolled 100 consecutive antiretroviral-naïve adult (age ≥18 years patients, who were followed for three months. Adherence was assessed by medication refill and three self-report measures (an AIDS Clinical Trial Group [ACTG] tool for four-day adherence, a visual analogue scale [VAS] and a rating task for 30-day adherence. The VAS represented a line anchored by 0 and 100% corresponding to the percentage of prescribed doses taken. The rating task asked patients to rate their ability to take all medications as prescribed, with responses categorized into six levels of adherence: very poor (0%, poor (20%, fair (40%, good (60%, very good (80% and excellent (100%. Patients with adherence of ≥95% by medication refill, ACTG and VAS, and ≥80% by rating task, were defined as adherent. Results: Of 100 patients enrolled, eight had missing data and were excluded from analysis. Among the remaining 92 patients, the median age was 39 years, and 70% were men. Major modes of HIV acquisition were injection drug use (IDU; 47.3% and heterosexual contact (44.1%. The proportions of adherent patients were as follows: 68% by medication refill, 90% by ACTG questionnaire, 38% by VAS and 42% by rating task. On average, four months after commencing ART, 52 (56.5% patients had a viral load <400 copies/ml and 26 (28.3% patients had a viral load <50 copies/ml. Of 43 persons with a history of IDU, 22 (51.2% reached a viral load of <400 copies/ml. In multivariate analysis, only refill adherence was a statistically significant predictor of viral suppression of <400 copies/ml: the risk ratio was 1.7 (95% CI: 1.1–2.8. Refill adherence, VAS and rating task were associated with viral

    In the absence of highly active therapy antiretroviral (HAART), adults with AIDS experience substantially elevated influenza-associated mortality in South Africa and the United States. This elevated mortality risk declined with widespread HAART introduction in the United States but did not disappear entirely. These data support increased access to HAART and influenza vaccination for human immunodeficiency virus–infected adults globally.

    Full Text Available Abstract Background To increase access to antiretroviral therapy in resource-limited settings, several experts recommend "task shifting" from doctors to clinical officers, nurses and midwives. This study sought to identify task shifting that has already occurred and assess the antiretroviral therapy training needs among clinicians to whom tasks have shifted. Methods The Infectious Diseases Institute, in collaboration with the Ugandan Ministry of Health, surveyed health professionals and heads of antiretroviral therapy clinics at a stratified random sample of 44 health facilities accredited to provide this therapy. A sample of 265 doctors, clinical officers, nurses and midwives reported on tasks they performed, previous human immunodeficiency virus training, and self-assessment of knowledge of human immunodeficiency virus and antiretroviral therapy. Heads of the antiretroviral therapy clinics reported on clinic characteristics. Results Thirty of 33 doctors (91%, 24 of 40 clinical officers (60%, 16 of 114 nurses (14% and 13 of 54 midwives (24% who worked in accredited antiretroviral therapy clinics reported that they prescribed this therapy (p Conclusion Training initiatives should be an integral part of the support for task shifting and ensure that antiretroviral therapy is used correctly and that toxicity or drug resistance do not reverse accomplishments to date.

    Full Text Available Background CD4 and viral loads are used in clinical trials as surrogate endpoints for assessing efficacy of newly available antiretrovirals. If antiretrovirals act through other pathways or negatively affect the risk of disease this would not be identified prior to licensing. The aims of this study were to investigate the CD4 and viral load specific rates of fatal and non-fatal AIDS and non-AIDS events according to current antiretrovirals. Methods Poisson regression was used to compare overall events (fatal or non-fatal AIDS, non-AIDS or death, AIDS events (fatal and non-fatal or non-AIDS events (fatal or non-fatal for specific nucleoside pairs and third drugs used with>1000 person-years of follow-up (PYFU after January 1st 2001.

    Given the realistic expectations of HIV-infected adolescents and young adults (AYA) to have children and start families, steps must be taken to ensure that youth are prepared to deal with the challenges associated with their HIV and parenting. Literature reviews were conducted to identify published research and practice guidelines addressing parenting or becoming parents among HIV-infected AYA in the United States. Research articles or practice guidelines on this topic were not identified. Given the paucity of information available on this topic, this article provides a framework for the development of appropriate interventions and guidelines for use in clinical and community-based settings. First, the social, economic, and sexual and reproductive health challenges facing HIV-infected AYA in the United States are summarized. Next, family planning considerations, including age-appropriate disclosure of HIV status to those who are perinatally infected, and contraceptive and preconception counseling are described. The impact of early childbearing on young parents is discussed and considerations are outlined during the preconception, antenatal, and postnatal periods with regard to antiretroviral medications and clinical care guidelines. The importance of transitioning AYA from pediatric or adolescent to adult-centered medical care is highlighted. Finally, a comprehensive approach is suggested that addresses not only medical needs but also emphasizes ways to mitigate the impact of social and economic factors on the health and well-being of these young parents and their children.

    Direct-to-consumer (DTC) prescription drug advertisements for HIV anti-retrovirals are controversial and have been criticized in the past for including deceptive images and underplaying HIV drug limitations. We sought to describe the state of recent DTC ads for HIV antiretrovirals in popular magazines by performing a content analysis of all complete DTC ads for antiretroviral medications appearing in eight national magazines during a one-year period. Current ads appear to have addressed previous concerns, but important problems still exist, such as failing to specify the medication's role in current treatment, to quantify drug efficacy, or to highlight life-threatening side effects.

    Full Text Available South Africa's national antiretroviral (ARV treatment program expanded in 2010 to include the nucleoside reverse transcriptase (RT inhibitors (NRTI tenofovir (TDF for adults and abacavir (ABC for children. We investigated the associated changes in genotypic drug resistance patterns in patients with first-line ARV treatment failure since the introduction of these drugs, and protease inhibitor (PI resistance patterns in patients who received ritonavir-boosted lopinavir (LPV/r-containing therapy.We analysed ARV treatment histories and HIV-1 RT and protease mutations in plasma samples submitted to the Tygerberg Academic Hospital National Health Service Laboratory.Between 2006 and 2012, 1,667 plasma samples from 1,416 ARV-treated patients, including 588 children and infants, were submitted for genotypic resistance testing. Compared with 720 recipients of a d4T or AZT-containing first-line regimen, the 153 recipients of a TDF-containing first-line regimen were more likely to have the RT mutations K65R (46% vs 4.0%; p<0.001, Y115F (10% vs. 0.6%; p<0.001, L74VI (8.5% vs. 1.8%; p<0.001, and K70EGQ (7.8% vs. 0.4% and recipients of an ABC-containing first-line regimen were more likely to have K65R (17% vs 4.0%; p<0.001, Y115F (30% vs 0.6%; p<0.001, and L74VI (56% vs 1.8%; p<0.001. Among the 490 LPV/r recipients, 55 (11% had ≥1 LPV-resistance mutations including 45 (9.6% with intermediate or high-level LPV resistance. Low (20 patients and intermediate (3 patients darunavir (DRV cross resistance was present in 23 (4.6% patients.Among patients experiencing virological failure on a first-line regimen containing two NRTI plus one NNRTI, the use of TDF in adults and ABC in children was associated with an increase in four major non- thymidine analogue mutations. In a minority of patients, LPV/r-use was associated with intermediate or high-level LPV resistance with predominantly low-level DRV cross-resistance.

    2016-05-01

    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.

    Full Text Available 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.

    AIDS is presently treatable, and patients can have a good prognosis due to the success of highly active antiretroviral therapy (HAART), but it is still not curable or preventable. High toxicity of HAART, and the emergence of drug resistance add to the imperative to continue research into new strategies and interventions.Considerable progress in the understanding of HIV attachment and entry into host cells has suggested new possibilities for rationally designing agents that interfere with this process. The approval and introduction of the fusion inhibitor enfuvirtide (Fuzeon) for clinical use signals a new era in AIDS therapeutics. Here we review the crucial steps the virus uses to achieve cell entry, which merit attention as potential targets, and the compounds at pre-clinical and clinical development stages, reported to effectively inhibit cell entry.

    Full Text Available Optic neuropathy in HIV-infected patients results from the HIV infection itself, post-infectious auto-immune disease, opportunistic infections and drugs. Nucleoside reverse transcriptase inhibitors (NRTIs such as zidovudine and stavudine have known mitochondrial toxicity and can cause mitochondrial myopathies, neuropathies, hyperlactataemia, and can induce mitochondrial genetic disorders. Individuals with the mutation for Leber’s hereditary optic neuropathy (LHON, a mitochondrial disorder, are usually asymptomatic but develop visual loss when exposed to external triggers such as smoking. We report on two HIV-infected patients with LHON mutations (m.14484T>C and m.11778G>A who developed profound visual loss with antiretroviral therapy. We postulate that the phenotypic expression of LHON in these genetically predisposed individuals was triggered by NRTI drugs lamivudine and tenofovir when used in combination, despite their relatively weak mitochondrial toxic effects.

    Antiretroviral medications such as tenofovir have been associated with Fanconi syndrome (FS) usually identified within the first 1-29 months after exposure to the medication. We present a case of life-threatening FS which developed in a 37-year-old woman with HIV after 8 years of asymptomatic tenofovir use. The patient was diagnosed with HIV in 1996 at 20 years of age, hepatitis C 10 years later, and Staphylococcus aureus sepsis with secondary osteomyelitis of the spine 3 years before admission for FS. She developed nausea, vomiting, diarrhea, and generalized weakness over a 2-week time period and presented to the hospital. In the emergency department, her serum potassium was 1.5 mEq/L, bicarbonate was 12 mEq/L, chloride was 111 mEq/L, phosphorus was 1.8 mg/dL, and creatinine was 1.95 mg/dL (baseline, 1.4). Arterial blood gas revealed a non-anion gap (hyperchloremic) metabolic acidosis. Type 2 renal tubular acidosis induced by antiretroviral therapy (ART) was suspected and the ART was discontinued with resolution of the renal abnormalities within 7 days. A non-tenofovir-containing ART regimen consisting of lamivudine/abacavir and efavirenz was begun, and over the next 8 months, the patient was without recurrence of the FS. This case report demonstrates the acute development of FS after prolonged exposure to tenofovir without exposure to additional nephrotoxins such as nonsteroidal medications or aminoglycosides. Tenofovir can cause FS at any time and should be considered in any patient presenting with renal tubular acidosis type 2 while on tenofovir regardless of the duration of drug exposure. PMID:24914503

Tenofovir can cause FS at any time and should be considered in any patient presenting with renal tubular acidosis type 2 while on tenofovir regardless of the duration of drug exposure.

    Background: There are few studies on pediatric HIV-HBV coinfection, so evidences about relationships between the two viruses are scarce. Objectives: influence of HBV infection on virological and immunological response to antiretroviral therapy (ART) in antiretroviral-naïve horizontally HIV-HBV coinfected subjects during early childhood. Material and methods: observational study on 826 HIV+ subjects in evidence of Craiova Regional Centre (CRC); we analyzed the immunological and virological response at 6-12 months after starting first antiretroviral regimens compared in 2 groups: horizontally HIV-HBV coinfected subjects during early childhood (CoS) versus horizontally HIV infected subjects during early childhood without HBV infection (non-CoS). Results: Number of subjects: CoS-66 subjects, non-CoS-132 subjects. Demographic data: CoS-gender ratio F:M=0.886, the majority lived in rural area (57.58%), mean age on diagnosis-9.288±4.607 years, non-CoS-gender ratio F:M=0.859, the majority lived in urban area (53.79%), mean age on diagnosis-10.742±5.107 years. At baseline, HIV category was: CoS-A-1.52%, B-80.30%, C-18.18%, non-CoS-A-2.27%, B-70.45%, C-27.27% (p Chi2=0.332), the mean CD4+ cell count was: CoS-148.33±148.10 cells/ml, non-CoS-163.17±155.39 cells/ml (p Student=0.521) and the mean HIV viral load (HIV VL) was: CoS-5.06±0.80 lgcopies/ml (for 29 subjects), non-CoS-5.04±0.84 lgcopies/ml (for 61 subjects) (p Student=0.978). At the end of the studied period, the mean increase in CD4+ cell count was: CoS-177.068±141.676 cells/ml, non-CoS-176.015±191.751 cells/ml (p Student=0.969) and the mean decrease in HIV VL was: CoS-5.04±0.79 lgcopies/ml, non-COS-4.69±2.04 lgcopies/ml (p Student=0.911). Conclusions: The presence of HBV coinfection does not influence immunological or virological response to ART. PMID:24778861

    Although crucial for efficacy of pharmacotherapy, adherence to prescribed medication regimens for both antiretrovirals and antidepressants is often suboptimal. As many depressed HIV-infected individuals are prescribed both antiretrovirals and antidepressants, it is important to know whether correlates of nonadherence are similar or different across type of regimen. The HIV Translating Initiatives for Depression into Effective Solutions (HI-TIDES) study was a single-blinded, longitudinal, randomized controlled effectiveness trial comparing collaborative care to usual depression care at three Veterans Affairs HIV clinics. The current investigation utilized self-report baseline interview and chart-abstracted data. Participants were 225 depressed HIV-infected patients who were prescribed an antidepressant (n=146), an antiretroviral (n=192), or both (n=113). Treatment adherence over the last 4 days was dichotomized as "less than 90% adherence" or "90% or greater adherence." After identifying potential correlates of nonadherence, we used a seemingly unrelated regression (SUR) bivariate probit model, in which the probability of adherence to HIV medications and the probability of adherence to antidepressant medications are modeled jointly. Results indicated that 75.5% (n=146) of those prescribed antiretrovirals reported 90%-plus adherence to their antiretroviral prescription and 76.7% (n=112) of those prescribed antidepressants reported 90%-plus adherence to their antidepressant prescription, while 67% of those prescribed both (n=113) reported more than 90% adherence to both regimens. SUR results indicated that education, age, and HIV symptom severity were significant correlates of antiretroviral medication adherence while gender and generalized anxiety disorder diagnosis were significant correlates of adherence to antidepressant medications. In addition, antiretroviral adherence did not predict antidepressant adherence (β=1.62, p=0.17), however, antidepressant adherence

    Full Text Available Throughout Asia, people who use drugs are confined in facilities referred to as compulsory drug detention and rehabilitation centers. The limited transparency and accessibility of these centers has posed a significant challenge to evaluating detainees and detention conditions directly. Despite HIV being highly prevalent in this type of confined setting, direct evaluation of detainees with HIV and their access to medical care has yet to be reported in the literature.We evaluated the health status of 100 adult male detainees with HIV and their access to medical care in the two largest Malaysian compulsory drug detention and rehabilitation centers holding HIV-infected individuals.Approximately 80% of all detainees with HIV were surveyed in each detention center. Most participants reported multiple untreated medical conditions. None reported being able to access antiretroviral therapy during detention and only 9% reported receiving any HIV-related clinical assessment or care. Nearly a quarter screened positive for symptoms indicative of active tuberculosis, yet none reported having been evaluated for tuberculosis. Although 95% of participants met criteria for opioid dependence prior to detention, none reported being able to access opioid substitution therapy during detention, with 86% reporting current cravings for opioids and 87% anticipating relapsing to drug use after release. Fourteen percent of participants reported suicidal ideation over the previous two weeks.We identified a lack of access to antiretroviral therapy in two of the six compulsory drug detention and rehabilitation centers in Malaysia designated to hold HIV-infected individuals and found significant, unmet health needs among detainees with HIV. Individuals confined under such conditions are placed at considerably high risk for morbidity and mortality. Our findings underscore the urgent need for evidence-based drug policies that respect the rights of people who use drugs and seek

    Full Text Available Background: An increase in tuberculosis (TB incidence has been associated with human immunodeficiency virus (HIV. Aims: To describe the clinical characteristics and treatment outcome of patients with HIV and miliary TB treated with short-course intermittent chemotherapy in the absence of access to highly active antiretroviral therapy (HAART. Settings and Design: Prospective study of HIV infected adults referred to a TB clinic between July 1999 and July 2004. Materials and Methods: On diagnosis of miliary TB, patients were treated with a standard regimen of two months of isoniazid, rifampicin, ethambutol and pyrazinamide followed by four months of isoniazid and rifampicin (2EHRZ 3 /4RH 3 thrice weekly and followed up for 24 months. Patients were reviewed clinically every month and two sputa were collected. Chest radiographs and blood investigations were done at two months, end of treatment and every six months thereafter. Results: Of 498 patients with HIV and tuberculosis, 31 (6% were diagnosed as miliary tuberculosis. At diagnosis, sputum smear was positive for acid-fast bacilli (AFB in 14 patients (45% and Mycobacterium tuberculosis was isolated in 21 (68%. The mean CD4 cell count was 129 ± 125 cells/mm 3 . Twenty-five patients were declared cured at the end of treatment (81% while one (3% died and five (16% failed. The recurrence rate was 19.4/100 person-years and the median survival was 17 months (95% CI 14 to 20. None of the patients received antiretroviral therapy. Conclusions: Miliary TB tends to occur among HIV infected patients with severe immunosuppression. Though the initial response to short-course chemotherapy was encouraging, a high recurrence rate and mortality was observed indicating poor prognosis in HIV.

    The scale-up of antiretroviral therapy (ART) in Malawi was based on a public health approach adapted to its resource-poor setting, with principles and practices borrowed from the successful tuberculosis control framework. From 2004 to 2015, the number of new patients started on ART increased from about 3000 to over 820,000. Despite being a small country, Malawi has made a significant contribution to the 15 million people globally on ART and has also contributed policy and service delivery innovations that have supported international guidelines and scale up in other countries. The first set of global guidelines for scaling up ART released by the World Health Organization (WHO) in 2002 focused on providing clinical guidance. In Malawi, the ART guidelines adopted from the outset a more operational and programmatic approach with recommendations on health systems and services that were needed to deliver HIV treatment to affected populations. Seven years after the start of national scale-up, Malawi launched a new strategy offering all HIV-infected pregnant women lifelong ART regardless of the CD4-cell count, named Option B+. This strategy was subsequently incorporated into a WHO programmatic guide in 2012 and WHO ART guidelines in 2013, and has since then been adopted by the majority of countries worldwide. In conclusion, the Malawi experience of ART scale-up has become a blueprint for a public health response to HIV and has informed international efforts to end the AIDS epidemic by 2030. PMID:27600800

    Full Text Available Abstract Background Abacavir has been associated with an increased risk of acute myocardial infarction, but the pathogenic mechanisms remain unknown. We evaluated longitudinal changes in pro-atherosclerotic biomarkers in patients initiating abacavir or tenofovir. Methods Consecutive patients initiating antiretroviral therapy (ART with abacavir/lamivudine or tenofovir/emtricitabine were included. Plasma levels of high sensitivity C reactive protein (hsCRP, interleukin-6 (IL-6, intercellular adhesion molecule-1, vascular cell adhesion molecule-1 (sVCAM-1 and plasminogen activator inhibitor-1 (PAI-1 were measured at baseline and at different time points throughout 48 weeks. Comparisons were adjusted for age, sex, ART status at inclusion, viral load, lipodystrophy, Framingham score and hepatitis C virus co-infection status. Results 50 patients were analyzed, 28 initiating abacavir and 22 tenofovir. The endothelial biomarker sVCAM-1 declined significantly in both treatment groups. hsCRP tended to increase soon after starting therapy with abacavir, a trend that was not seen in those initiating tenofovir. IL-6 significantly increased only at week 24 from baseline in patients on abacavir (+225%, p Conclusion Changes in biomarkers of inflammation, coagulation, and endothelial function are not different in viremic patients starting ART with abacavir/lamivudine or tenofovir/emtricitabine. These changes occur in the early phases of treatment and include anti- and pro-atherosclerotic effects with both drugs.

    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.

    2014-01-01

    Introduction This study aimed at estimating the incidence of pregnancy after antiretroviral therapy (ART) initiation in eight West African countries over a 10-year period. Methods A retrospective analysis was conducted within the international database of the IeDEA West Africa Collaboration. All HIV-infected women aged <50 years and starting ART for their own health between 1998 and 2011 were eligible. Pregnancy after ART initiation was the main outcome and was based on clinical reporting. Poisson regression analysis accounting for country heterogeneity was computed to estimate first pregnancy incidence post-ART and to identify its associated factors. Pregnancy incidence rate ratios were adjusted on country, baseline CD4 count and clinical stage, haemoglobin, age, first ART regimen and calendar year. Results Overall 29,425 HIV-infected women aged 33 years in median [Inter Quartile Range: 28–38] contributed for 84,870 women-years of follow-up to this analysis. The crude incidence of first pregnancy (2,304 events) was 2.9 per 100 women-years [95% confidence interval [CI]: 2.7–3.0], the highest rate being reported among women aged 25–29 years: 4.7 per 100 women-years; 95% CI: 4.3–5.1. The overall Kaplan-Meier probability of pregnancy occurrence by the fourth year on ART was 10.9% (95% CI: 10.4–11.4) and as high as 28.4% (95% CI: 26.3–30.6) among women aged 20–29 years at ART initiation. Conclusion The rate of pregnancy occurrence after ART initiation among HIV-infected women living in the West Africa region was high. Family planning services tailored to procreation needs should be provided to all HIV-infected women initiating ART and health consequences carefully monitored in this part of the world.

    Kathryn Stinson

    Full Text Available OBJECTIVES: Initiation of antiretroviral therapy (ART during pregnancy is critical to promote maternal health and prevent mother-to-child HIV transmission (PMTCT. The separation of services for antenatal care (ANC and ART may hinder antenatal ART initiation. We evaluated ART initiation during pregnancy under different service delivery models in Cape Town, South Africa. METHODS: A retrospective cohort study was conducted using routinely collected clinic data. Three models for ART initiation in pregnancy were evaluated ART 'integrated' into ANC, ART located 'proximal' to ANC, and ART located some distance away from ANC ('distal'. Kaplan-Meier methods and Poisson regression were used to examine the association between service delivery model and antenatal ART initiation. RESULTS: Among 14 617 women seeking antenatal care in the three services, 30% were HIV-infected and 17% were eligible for ART based on CD4 cell count <200 cells/µL. A higher proportion of women started ART antenatally in the integrated model compared to the proximal or distal models (55% vs 38% vs 45%, respectively, global p = 0.003. After adjusting for age and gestation at first ANC visit, women who at the integrated service were significantly more likely to initiate ART antenatally (rate ratio 1.33; 95% confidence interval: 1.09-1.64 compared to women attending the distal model; there was no difference between the proximal and distal models in antenatal ART initiation however (p = 0.704. CONCLUSIONS: Integration of ART initiation into ANC is associated with higher levels of ART initiation in pregnancy. This and other forms of service integration may represent a valuable intervention to enhance PMTCT and maternal health.

  17. Food insecurity as a barrier to sustained antiretroviral therapy adherence in Uganda.

    Directory of Open Access Journals (Sweden)

    Sheri D Weiser

    Full Text Available BACKGROUND: Food insecurity is emerging as an important barrier to antiretroviral (ARV adherence in sub-Saharan Africa and elsewhere, but little is known about the mechanisms through which food insecurity leads to ARV non-adherence and treatment interruptions. METHODOLOGY: We conducted in-depth, open-ended interviews with 47 individuals (30 women, 17 men living with HIV/AIDS recruited from AIDS treatment programs in Mbarara and Kampala, Uganda to understand how food insecurity interferes with ARV therapy regimens. Interviews were transcribed, coded for key themes, and analyzed using grounded theory. FINDINGS: Food insecurity was common and an important barrier to accessing medical care and ARV adherence. Five mechanisms emerged for how food insecurity can contribute to ARV non-adherence and treatment interruptions or to postponing ARV initiation: 1 ARVs increased appetite and led to intolerable hunger in the absence of food; 2 Side effects of ARVs were exacerbated in the absence of food; 3 Participants believed they should skip doses or not start on ARVs at all if they could not afford the added nutritional burden; 4 Competing demands between costs of food and medical expenses led people either to default from treatment, or to give up food and wages to get medications; 5 While working for food for long days in the fields, participants sometimes forgot medication doses. Despite these obstacles, many participants still reported high ARV adherence and exceptional motivation to continue therapy. CONCLUSIONS: While reports from sub-Saharan Africa show excellent adherence to ARVs, concerns remain that these successes are not sustainable in the presence of widespread poverty and food insecurity. We provide further evidence on how food insecurity can compromise sustained ARV therapy in a resource-limited setting. Addressing food insecurity as part of emerging ARV treatment programs is critical for their long-term success.

    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

    Full Text Available Abstract Background Central nervous system (CNS exposure to HIV is a universal facet of systemic infection. Because of its proximity to and shared barriers with the brain, cerebrospinal fluid (CSF provides a useful window into and model of human CNS HIV infection. Methods Prospective study of the relationships of CSF to plasma HIV RNA, and the effects of: 1 progression of systemic infection, 2 CSF white blood cell (WBC count, 3 antiretroviral therapy (ART, and 4 neurological performance. One hundred HIV-infected subjects were cross-sectionally studied, and 28 were followed longitudinally after initiating or changing ART. Results In cross-sectional analysis, HIV RNA levels were lower in CSF than plasma (median difference 1.30 log10 copies/mL. CSF HIV viral loads (VLs correlated strongly with plasma VLs and CSF WBC counts. Higher CSF WBC counts associated with smaller differences between plasma and CSF HIV VL. CSF VL did not correlate with blood CD4 count, but CD4 counts In subjects starting ART, those with lower CD4 counts had slower initial viral decay in CSF than in plasma. In all subjects, including five with persistent plasma viremia and four with new-onset ADC, CSF HIV eventually approached or reached the limit of viral detection and CSF pleocytosis resolved. Conclusion CSF HIV infection is common across the spectrum of infection and is directly related to CSF pleocytosis, though whether the latter is a response to or a contributing cause of CSF infection remains uncertain. Slowing in the rate of CSF response to ART compared to plasma as CD4 counts decline indicates a changing character of CSF infection with systemic immunological progression. Longer-term responses indicate that CSF infection generally responds well to ART, even in the face of systemic virological failure due to drug resistance. We present simple models to explain the differing relationships of CSF to plasma HIV in these settings.

    Yang, Jun; Liu, Wenqing; Liu, Pei

    Blackout of large area is a serious threat to modern power system, so power system restoration which is called Black Start is a critical task for reducing economic losses and social unrest caused by blackout. Traditiona black start sometimes may suffer from inflexible black start units and overvoltage and serious oscillation. As a power storage unit, SMES has the ability of fast exchanging active and reactive power with power grid in all four quadrants, so it is proposed as a new solution to improve the black start process in this paper. Comparing to traditional black start, some unique advantages of SMES for black start are presented. Also SMES model and related control strategy are introduced in detail. A simulation model is established based on PSCAD/EMTDC to investigate the validity and flexibility of SMES in black start. Simulation results show that SMES unit can bring thermal generators online, and it has better performance on overvoltage restraint and amping oscillation than traditional black start. Also, the performance of nonlinear PID-controlled SMES is better than that of PID-controlled SMES.

    Background CD4~+ T cell counts have been used as the indicator of human immunodeficiency virus type 1 (HIV-1) disease progression and thereby to determine when to start highly active antiretroviral therapy (HAART). Whether and how the baseline CD4~+T cell count affects the immunological and viral responses or adverse reactions to nevirapine (NVP)-containing HAART in Chinese HIV-1 infected adults remain to be characterized.Methods One hundred and ninety-eight HIV-seropositive antiretroviral therapy (ART)-naive subjects were enrolled into a prospective study from 2005 to 2007. Data were analyzed by groups based on baseline CD4~+T cell counts either between 100-200 cells/μl or 201-350 cells/pl. Viral responses, immunologic responses and adverse events were monitored at baseline and at weeks 4, 12, 24, 36, 52, 68, 84, 100.Results Eighty-six and 112 subjects ranged their CD4~+T cell counts 100-200 cells/μl and 201-350 cells/μl, respectively.The pre-HAART viral load in CD4 201-350 cells/μl group was significantly lower than that in CD4 100-200 cells/μl group (P=0.000). After treatment, no significant differences were observed between these two groups either in the plasma viral load (pVL) or in the viral response rate calculated as the percentage of pVL less than 50 copies/μl or less than 400 copies/ml. The CD4~+T cell counts were statistically higher in the 201-350 group during the entire follow-ups (P<0.01) though CD4~+ T cell count increases were similar in these two groups. After 100-week treatment, the median of CD4~+ T cell counts were increased to 331 cells/μl for CD4 100-200 cells/μl group and to 462 cells/μl for CD4 201-350 cells/μl group.Only a slightly higher incidence of nausea was observed in CD4 201-350 cells/μl group (P=0.05) among all adverse reactions, including rash and liver function abnormality.Conclusions The pVLs and viral response rates are unlikely to be associated with the baseline CD4~+T cell counts.

    START is a tool to optimize research and development primarily for NASA missions. It was developed within the Strategic Systems Technology Program Office, a division of the Office of the Chief Technologist at NASA's Jet Propulsion Laboratory. START is capable of quantifying and comparing the risks, costs, and potential returns of technologies that are candidates for funding. START can be enormously helpful both in selecting technologies for development -- within the constraints of budget, schedule, and other resources -- and in monitoring their progress. START's methods are applicable to everything from individual tasks to multiple projects comprising entire programs of investigation. They can address virtually any technology assessment and capability prioritization issue. In this report, START is used to analyze the capability needs using data from NASA's Exploration Systems Architecture Study (ESAS).

    From December 2005 through August 2008, we provided community-based accompaniment with supervised antiretroviral therapy (CASA) to impoverished individuals starting highly active antiretroviral therapy. Adherence support was provided for 18 months by a community-based team comprised of several nurses and two types of community health workers: field supervisors and directly observed therapy (DOT) volunteers. To complement our quantitative data collection in 2008 using purposive sampling, we conducted two gender-mixed focus group discussions with 13 CASA patient participants and 13 DOT volunteers from Lima, Peru to identify the mediating mechanisms by which CASA improved well-being, and to understand the benefits of the intervention, as perceived by these individuals. Using standard qualitative methods for the review and analysis of transcripts and interview notes, we identified central themes and developed a coding scheme for categorising participants' statements. Two individuals blinded to each other's coding, coded interview transcripts for theme and content from which a third reviewer compared their coding to arbitrate discrepancies. Additional domains were added if necessary and all domains were integrated into a theoretical scheme. Among the forms of support delivered by the CASA team, DOT volunteers reported emotional support, instrumental support, directly observed therapy, building trust, education, advocacy, exercise of moral authority and preparation for transition off CASA support. CASA participants described outcomes of improved adherence, ability to resume social roles, increased self-efficacy, hopefulness, changes in non-HIV-related behaviour, reduced internalised and externalised stigma, as well as ability to disclose. Both sets of focus group participants highlighted remaining challenges after completion of CASA support: stigma in the community, difficulties achieving economic recovery and persistent barriers to health services.

    2011-10-01

    Full Text Available Antiretrovirals are prone to drug-drug and drug-food interactions that can result in subtherapeutic or supratherapeutic concentrations. Interactions between antiretrovirals and medications for other diseases are common due to shared metabolism through cytochrome P450 (CYP450 and uridine diphosphate glucuronosyltransferase (UGT enzymes and transport by membrane proteins (e.g., p-glycoprotein, organic anion-transporting polypeptide. The clinical significance of antiretroviral drug interactions is reviewed, with a focus on new and investigational agents. An overview of the mechanistic basis for drug interactions and the effect of individual antiretrovirals on CYP450 and UGT isoforms are provided. Interactions between antiretrovirals and medications for other co-morbidities are summarized. The role of therapeutic drug monitoring in the detection and management of antiretroviral drug interactions is also briefly discussed.

    2011-01-01

    Background While antiretroviral treatment (ART)-related adverse drug reactions (ADR) are documented in industrialized countries, there is no pre-existing surveillance system dedicated to ADR monitoring in most African countries. We assessed knowledge towards pharmacovigilance among ART prescribers and available capacity of HIV clinics to conduct ADR monitoring in Abidjan, Côte d’Ivoire. Methods A questionnaire was administered to ART prescribers, to assess their knowledge towards the occurrence of ADRs. A retrospective ADR survey was also conducted, based on a data query of treatment modification/interruptions in three HIV clinics. Clinical monitors went back to medical charts to review and validate the reasons of the treatment modification/interruptions. Results Of the 81 ART prescribers interviewed, 25 (31%) declared not grading ADRs and 12 (14.8%) declared notifying ADRs to the national regulatory authorities. Among 5,252 adult ART-treated patients who attended the participating clinics in 2008, 599 treatment modifications were identified. Reasons for treatment modification/interruptions identified in the electronic database were documented in the medical charts in 554 (92.5%) cases, ADR accounting for 273 (45.5%) cases. Toxicity related to ART was graded in only 58 (21%) cases in the medical charts. Discussion This study describes challenges limiting the implementation of reliable pharmacovigilance activities in HIV clinics in Côte d’Ivoire. The lack of knowledge of ART prescribers concerning ADR grading does not support the spontaneous reporting of ADRs. Using treatment modification/interruptions for ADR monitoring appears feasible but improvements are needed to respond to key questions related to drug toxicities in the context of ART scale up in Africa.

    Full Text Available OBJECTIVE: To evaluate the prevalence of and the associated factors for metabolic syndrome (MS among Latin American HIV-infected patients receiving antiretroviral therapy (ART using baseline data from the RAPID II study. METHODS: A longitudinal study to evaluate the metabolic profile, cardiovascular disease (CVD risk and associated treatment practices to reduce this risk has been conducted in seven Latin American countries (the RAPID II study. Adult HIV patients with at least six months of RT were enrolled. MS was defined following ATP-III criteria. Demographic and anthropometric data, serum biochemical and clinical parameters were compared in patients with and without MS using bivariate and multivariate analysis. RESULTS: A total of 4,010 patients were enrolled, 2,963 (74% were males. Mean age (SD was 41.9 (10.0 years. The prevalence of MS was 20.2%. Females had higher prevalence of MS than males (22.7% vs. 19.4%, p = 0.02. MS was driven by high triglycerides, low HDL-cholesterol and high blood pressure (HBP. Patients with MS had higher 10year CVD risk: 22.2% vs. 7.4%, p < 0.001. Age (OR: 1.05 per year, female gender (OR: 1.29, family history of CVD (OR: 1.28, CD4 cell count (OR: 1.09 per 100 cell increase, and protease inhibitor based-ART (OR: 1.33 correlated with MS in the multivariate analysis. CONCLUSIONS: Prevalence of MS in this setting was similar to that reported from developed countries. MS was driven by high triglycerides, low-HDL and HBP, and it was associated with higher risk of CVD. Traditional risk factors, female gender, immune reconstitution, and protease inhibitor based-ART correlated with MS.

    Full Text Available 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.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.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.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.

  12. Bezafibrate for the treatment of hypertriglyceridemia in HIV1-infected patients on highly active antiretroviral therapy

    Full Text Available The use of highly active antiretroviral therapy (HAART in HIV-infected patients has been associated with the development of risk factors for cardiovascular diseases (CD including dyslipidemia and insulin resistance, hypertriglyceridemia being the most frequent metabolic disturbance in these patients. Fibrates are indicated when hypertriglyceridemia is accentuated and persists for over six months. We evaluated the efficacy and safety of bezafibrate for the treatment of hypertriglyceridemia in HIV-infected individuals on HAART. All patients received 400mg/day of bezafibrate and were evaluated three times: Mo (pre-treatment, M1 (one month after treatment, and M2 (six months after treatment. Fifteen adult individuals, eight males and seven females with mean age = 41.2 ± 7.97 years and triglyceride serum levels > 400mg/dL were included in the study. Smoking, alcohol ingestion and sedentarism rates were 50%, 6.66% and 60%, respectively. Family history of CD, hypertension and diabetes mellitus was reported in 33.3%, 40% and 46.7% of the cases, respectively, while dyslipidemia was reported by only 13.3%. More than half of the patients were using a protease inhibitor plus a nucleotide analog transcriptase inhibitor. Eutrophy and tendency toward overweight were observed at all three study time points. There were significant reductions in triglyceride serum levels from Mo to M1 and from Mo to M2. No significant changes were observed in the serum levels of creatine phosphokinase, hepatic enzymes, CD4+, CD8+ and viral load. Therefore, bezafibrate seems to be safe and effective for the reduction of hypertriglyceridemia in HIV-infected patients on HAART.

    Full Text Available There is limited data on the prevalence of depression in HIV and AIDS patients in Sub- Saharan Africa and little resources have been allocated to address this issue. Depression affects patient adherence to treatment and predisposes patients to resistance which poses a public health threat. It also affects quality of life and productivity of patients. From August 2008 to March 2009, 731 patient adherence surveys were administered to assess disease, treatment knowledge and services received. The primary variable of interest was patients’ level of depressive symptoms score, constructed using factor analysis from five survey questions relating to: sadness, need to be alone, hopelessness and confusion and was categorized as no depressive symptoms (score 0, low depressive symptoms (score 1-2, moderate depressive symptoms (score 3-4 and high depressive symptoms (score 5-10. Majority of the patients on highly active antiretroviral therapy (HAART (59% were found to have depressive symptoms and this was more among women than men (66% vs 43%. There was some association of depressive symptoms with non-disclosure (70% of those who had not disclosed had depressive symptoms compared to 53% among those who had disclosed. There is a high prevalence of depressive symptoms among adult patients on HAART. There is need for in-depth evaluation to find out the root causes of depressive symptoms among HAART patients in AIDSRelief clinics. There is need to integrate mental health management in HIV care and treatment as well as training the existing health workers on mental health management.

    Background Lopinavir/ritonavir (LPV/r) is widely used in Cambodia with high efficacy but scarce data exist on long-term metabolic toxicity. Methods We carried out a cross-sectional and retrospective study evaluating metabolic disorders and cardiovascular risk in Cambodian patients on LPV/r-based antiretroviral therapy (ART) for > 1 year followed in Calmette Hospital, Phnom Penh. Data collected included cardiovascular risk factors, fasting blood lipids and glucose, and retrospective collection of bioclinical data. We estimated the 10-year risks of coronary heart disease with the Framingham, Ramathibodi-Electricity Generating Authority of Thailand (Rama-EGAT), and the Data Collection on Adverse Effects of Anti-HIV Drugs (D:A:D) risk equations. We identified patients with LDL above targets defined by the French expert group on HIV and by the HIV Medicine Association of the Infectious Disease Society of America and the Adult AIDS Clinical Trials Group (IDSA-AACTG). Results Of 115 patients enrolled—mean age 40.9 years, 69.2% male, mean time on LPV/r 3.8 years—40 (34.8%) had hypercholesterolemia (> 2.40 g/L), and 69 (60.0%) had low HDL cholesterol (< 0.40 g/L). Twelve (10.5%), 28 (24%) and 9 (7.7%) patients had a 10-year risk of coronary heart disease ≥ 10% according to the Framingham, D:A:D, and Rama-EGAT score, respectively. Fifty one (44.4%) and 36 (31.3%) patients had not reached their LDL target according to IDSA-AACTG and French recommendations, respectively. Conclusion Prevalence of dyslipidemia was high in this cohort of HIV-infected Cambodian patients on LPV/r. Roughly one third had high LDL levels requiring specific intervention. PMID:27579612

    Voltage regulator bypassed to supply starting current. Starting or "pullup" circuit supplies large inrush of current required by erasable programmable logic device (EPLD) while being turned on. Operates only during such intervals of high demand for current and has little effect any other time. Performs needed bypass, acting as current-dependent shunt connecting battery or other source of power more nearly directly to EPLD. Input capacitor of regulator removed when starting circuit installed, reducing probability of damage to transistor in event of short circuit in or across load.

    Full Text Available Abstract Background Ensuring good adherence is critical to the success of anti-retroviral treatment (ART. However, in resource-poor contexts, where paediatric HIV burden is high there has been limited progress in developing or adapting tools to support adherence for HIV-infected children on ART and their caregivers. We conducted formative research to assess children's adherence and to explore the knowledge, perceptions and attitudes of caregivers towards children's treatment. Methods All children starting ART between September 2002 and January 2004 (when ART was at cost in Malawi were observed for at least 6 months on ART. Their adherence was assessed quantitatively by asking caregivers of children about missed ART doses during the previous 3 days at monthly visits. Attendance to clinic appointments was also monitored. In June and July 2004, four focus group discussions, each with 6 to 8 caregivers, and 5 critical incident narratives were conducted to provide complementary contextual data on caregivers' experiences on the challenges to and opportunities of paediatric ART adherence. Results We followed prospectively 47 children who started ART between 8 months and 12 years of age over a median time on ART of 33 weeks (2–91 weeks. 72% (34/47 never missed a single dose according to caregivers' report and 82% (327/401 of clinic visits were either as scheduled, or before or within 1 week after the scheduled appointment. Caregivers were generally knowledgeable about ART and motivated to support children to adhere to treatment despite facing multiple challenges. Caregivers were particularly motivated by seeing children begin to get better; but faced challenges in meeting the costs of medicine and transport, waiting times in clinic, stock outs and remembering to support children to adhere in the face of multiple responsibilities. Conclusion In the era of rapid scale-up of treatment for children there is need for holistic support strategies that focus

    HIV drug resistance still represents a crucial problem in antiretroviral therapy. We report a case of a naive patient, harboring a CRF11-cpx virus, which showed drug resistance mutations in the reverse transcriptase. A drug resistance genotyping test was performed for the pol (protease, reverse transcriptase, and integrase) and V3 regions. The initial clinical parameter results showed a 4 log level of HIV-RNA (12,090 cp/ml) and a very low CD4(+) cell count (35 cells/μl). We designed an initial highly active antiretroviral therapy (HAART) regimen including lamivudine (3TC)+abacavir (ABC)+booster ritonavir (DRV/r). The virus was highly resistant to all nucleoside and nucleotide reverse transcriptase inhibitors (NRTIs) and nonnucleoside reverse transcriptase inhibitors (NNRTIs) except for ABC, tenofovir (TDF), and efavirenz (EFV) and was susceptible to all protease inhibitors (PIs) and integrase inhibitors (INIs). A salvage regimen including raltegravir (RAL)+DRV/r was started. Ten months later, the immunovirological status shows CD4(+) 142/μl and HIV-RNA <37 cp/ml. Our results demonstrate the effectiveness of a treatment combination that includes RAL+DRV/r in a patient infected with a complex X4-tropic CRF11-cpx virus. PMID:24279648

    Full Text Available Abstract In a routine service delivery setting in Uganda, we assessed the ability of the WHO clinical stage to accurately identify HIV-infected patients in whom antiretroviral therapy should be started. Among 4302 subjects screened for ART, the sensitivity and specificity (95% CI of WHO stage III, IV against a CD4 count 6/l were 52% (50, 54% and 68% (66, 70% respectively. Plasma viral load was tested in a subset of 1453 subjects in whom ART was initiated. Among 938 subjects with plasma viral load of 100,000 copies or more, 391 (42%, 95% CI 39, 45% were at WHO stage I or II. In this setting, a large number of individuals could have been denied access to antiretroviral therapy if eligibility to ART was assessed on the basis of WHO clinical stage. There is an urgent need for greater CD4 count testing and evaluation of the utility of plasma viral load prior to initiation of ART to accompany the roll-out of ART.

    HIV drug resistance still represents a crucial problem in antiretroviral therapy. We report a case of a naive patient, harboring a CRF11-cpx virus, which showed drug resistance mutations in the reverse transcriptase. A drug resistance genotyping test was performed for the pol (protease, reverse transcriptase, and integrase) and V3 regions. The initial clinical parameter results showed a 4 log level of HIV-RNA (12,090 cp/ml) and a very low CD4(+) cell count (35 cells/μl). We designed an initial highly active antiretroviral therapy (HAART) regimen including lamivudine (3TC)+abacavir (ABC)+booster ritonavir (DRV/r). The virus was highly resistant to all nucleoside and nucleotide reverse transcriptase inhibitors (NRTIs) and nonnucleoside reverse transcriptase inhibitors (NNRTIs) except for ABC, tenofovir (TDF), and efavirenz (EFV) and was susceptible to all protease inhibitors (PIs) and integrase inhibitors (INIs). A salvage regimen including raltegravir (RAL)+DRV/r was started. Ten months later, the immunovirological status shows CD4(+) 142/μl and HIV-RNA <37 cp/ml. Our results demonstrate the effectiveness of a treatment combination that includes RAL+DRV/r in a patient infected with a complex X4-tropic CRF11-cpx virus.

    Since the onset of the human immunodeficiency virus (HIV) epidemic, the care of infected patients improved dramatically. Whereas the disease was almost always fatal, the development of new drugs and new therapeutic strategies now allow a prolonged survival. However, the complexity of patient care is increasing and physicians face new clinical events and treatment toxicities. Recent molecules and follow-up according to the recent French recommendations will be presented here. The objectives of the treatment is to decrease mortality and morbidity of the HIV infection, by restoring near normal CD4+ T cell counts and qualitative T CD4+ responses, associated with a sustained reduction in viral replication. This objective must be reached by minimizing toxicity of antiretroviral drugs. Newly developed drugs that are better-tolerated and new therapeutic classes should improve outcome at all stages of HIV infection. Whereas viral eradication remains unrealistic and protective vaccines will not be soon available, direct consequences of long term HIV infection and issues related to an ageing HIV infected population raise up new research topics. Prevention of new infections, improvement in the precocity of care by a better-targeted screening and assessment of therapy before an established immune deficiency appear as the main priorities for the coming years.

    Full Text Available We present a 16-year-old boy, who had presented to us with catatonic features of mutism, withdrawal, passive negativism, grimacing, gesturing, echopraxia, and excitement of 5 days duration while taking antiretroviral therapy (ART for a period of 2 years. He had history of birth asphyxia and acquired HIV infection from his father when the same syringe and needle was used on both of them in a medical setting where the father and son had consulted for treatment of pyrexia of unknown origin. He was the eldest of a three children family in which the biologic father had acquired HIV through extramarital sexual contact with HIV-infected sex workers but was unaware of his HIV positive status till our patient, the 16-year-old was admitted and treated for pulmonary tuberculosis at 14 years of age. The boy′s mother had only acquired HIV after having three children with the HIV-positive husband, thus leaving the other two children HIV negative. The catatonia completely resolved within 2 days after the ART was withheld, and risperidone 1 mg twice a day was prescribed. This case highlights the risks of ART and breach of universal precautions.

    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

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

    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.

    Oropharyngeal candidiasis (OPC) remains a common problem in the HIV-infected population despite the availability of antiretroviral therapy (ART). Although Candida albicans is the most frequently implicated pathogen, other Candida spp. may also cause infection. The emergence of antifungal resistance within these causative yeasts, especially in patients with recurrent oropharyngeal infection or with long-term use of antifungal therapies, requires a working knowledge of alternative antifungal agents. Identification of the infecting organism and antifungal susceptibility testing enhances the ability of clinicians to prescribe appropriate antifungal therapy. Characterization of the responsible mechanisms has improved our understanding of the development of antifungal resistance and could enhance the management of these infections. Immune reconstitution has been shown to reduce rates of oropharyngeal candidiasis but few studies have evaluated the current impact of ART on the epidemiology of oropharyngeal candidiasis and antifungal resistance in these patients. Preliminary results from an ongoing clinical study showed that in patients with advanced AIDS oral yeast colonization was extensive, occurring in 81.1% of the 122 patients studied and symptomatic infection occurred in a third. In addition, resistant yeasts were still common occurring in 25.3% of patients colonized with yeasts or with symptomatic infection. Thus, oropharyngeal candidasis remains a significant infection in advanced AIDS even with ART. Current knowledge of the epidemiology, pathogenesis, clinical presentation, treatment, and mechanisms of antifungal resistance observed in oropharyngeal candidiasis are important in managing patients with this infection and are the focus of this review.

    Full Text Available Introduction: PREVALEAT II (PREmature VAscular LEsions and Antiretroviral Therapy II is an ongoing multicenter, longitudinal cohort study aimed to the evaluation of cardiovascular (CV risk in advanced HIV-infected antiretroviral (ARV naïve patients starting their first antiretroviral therapy (ART. Patients and methods: All consecutive naïve patients with CD4 cell count 200. Conclusions: Our data evidence at baseline has a relevant deterioration of CV conditions in terms of ultrasonographic data, FMD, inflammation and cytokine markers among advanced naïves. During follow-up epi-aortic lesions tend to worsen but not significantly, percentage of pathologic FMD remains stable. Regarding markers of endothelial activation ICAM-1 significantly worsens during the period of observation; also VCAM-1 has a trend towards the worsening while not significantly. Conversely, a significant improvement was observed for the markers of inflammation D-dimers and high sensitivity C-reactive protein (hsCRP. IL-6 improved but not significantly. Serum lipid profile shows an increase of HDLc and total cholesterol, but not of LDLc. In conclusion, after a twelve-month follow-up period, CV risk of the patients remains high. ARV therapy seems in fact to improve only non-specific and poor sensitive inflammation biomarkers and HDLc; markers of endothelial activations tend to worsen, intima-media ultrasonography and FMD do not show relevant modifications. Further data are warranted to better understand the role of the different ARV regimens.

    Full Text Available BACKGROUND: Since 2005, increasing numbers of children have started antiretroviral therapy (ART in sub-Saharan Africa and, in recent years, WHO and country treatment guidelines have recommended ART initiation for all infants and very young children, and at higher CD4 thresholds for older children. We examined temporal changes in patient and regimen characteristics at ART start using data from 12 cohorts in 4 countries participating in the IeDEA-SA collaboration. METHODOLOGY/PRINCIPAL FINDINGS: Data from 30,300 ART-naïve children aged <16 years at ART initiation who started therapy between 2005 and 2010 were analysed. We examined changes in median values for continuous variables using the Cuzick's test for trend over time. We also examined changes in the proportions of patients with particular disease severity characteristics (expressed as a binary variable e.g. WHO Stage III/IV vs I/II using logistic regression. Between 2005 and 2010 the number of children starting ART each year increased and median age declined from 63 months (2006 to 56 months (2010. Both the proportion of children <1 year and ≥10 years of age increased from 12 to 19% and 18 to 22% respectively. Children had less severe disease at ART initiation in later years with significant declines in the percentage with severe immunosuppression (81 to 63%, WHO Stage III/IV disease (75 to 62%, severe anemia (12 to 7% and weight-for-age z-score<-3 (31 to 28%. Similar results were seen when restricting to infants with significant declines in the proportion with severe immunodeficiency (98 to 82% and Stage III/IV disease (81 to 63%. First-line regimen use followed country guidelines. CONCLUSIONS/SIGNIFICANCE: Between 2005 and 2010 increasing numbers of children have initiated ART with a decline in disease severity at start of therapy. However, even in 2010, a substantial number of infants and children started ART with advanced disease. These results highlight the importance of efforts to

    Full Text Available Introduction: Long-term survival of HIV patients after initiating highly active antiretroviral therapy (ART has not been sufficiently described in Latin America and the Caribbean, as compared to other regions. The aim of this study was to describe the incidence of mortality, loss to follow-up (LTFU and associated risk factors for patients enrolled in the Caribbean, Central and South America Network (CCASAnet. Methods: We assessed time from ART initiation (baseline to death or LTFU between 2000 and 2014 among ART-naïve adults (≥18 years from sites in seven countries included in CCASAnet: Argentina, Brazil, Chile, Haiti, Honduras, Mexico and Peru. Kaplan-Meier techniques were used to estimate the probability of mortality over time. Risk factors for death were assessed using Cox regression models stratified by site and adjusted for sex, baseline age, nadir pre-ART CD4 count, calendar year of ART initiation, clinical AIDS at baseline and type of ART regimen. Results: A total of 16,996 ART initiators were followed for a median of 3.5 years (interquartile range (IQR: 1.6–6.2. The median age at ART initiation was 36 years (IQR: 30–44, subjects were predominantly male (63%, median CD4 count was 156 cells/µL (IQR: 60–251 and 26% of subjects had clinical AIDS prior to starting ART. Initial ART regimens were predominantly non-nucleoside reverse transcriptase inhibitor based (86%. The cumulative incidence of LTFU five years after ART initiation was 18.2% (95% confidence interval (CI 17.5–18.8%. A total of 1582 (9.3% subjects died; the estimated probability of death one, three and five years after ART initiation was 5.4, 8.3 and 10.3%, respectively. The estimated five-year mortality probability varied substantially across sites, from 3.5 to 14.0%. Risk factors for death were clinical AIDS at baseline (adjusted hazard ratio (HR=1.65 (95% CI 1.47–1.87; p<0.001, lower baseline CD4 (HR=1.95 (95% CI 1.63–2.32 for 50 vs. 350 cells/µL; p<0.001 and
