Abstract
INTRODUCTION With longer life expectancy in people living with HIV (PLWH) on antiretroviral therapy, cardiovascular disease (CVD) has become a common cause of mortality among them. Abacavir has been associated with an increased risk of myocardial infarction, but the mechanism is unknown. Additionally, abacavir may be obesogenic which could mediate an additional risk factor of CVD. We aim to investigate if discontinuation of abacavir will have a favourable impact on body weight and cardiac parameters in PLWH. METHODS AND ANALYSIS Randomised, controlled, superiority trial of virologically suppressed PLWH on dolutegravir, abacavir and lamivudine (DTG/ABC/3TC) for ≥6 months. In total, 70 PLWH will be randomised 1:2 to either continue DTG/ABC/3TC or to switch to dolutegravir and lamivudine (DTG/3TC) providing the power of 80% at alpha 5% to detect a mean difference in weight change of 2 kg (Δ) given an SD of 2.7 kg. Follow-up will be 48 weeks. Data will be collected at baseline and week 48. Primary outcome will be change in mean body weight from baseline to week 24 and 48 evaluated in a linear mixed model. Secondary outcomes will be changes in cardiac, inflammatory and metabolic parameters, fat distribution, coagulation, endothelial, platelet function, quality of life and virological control from baseline to week 48. Measurements include CT of thorax and abdomen, external carotid artery ultrasound, liver elastography and dual energy X-ray absorptiometry and blood analysis. Plasma HIV RNA will be measured at baseline, week 4, 24 and 48. Forty participants (20 from each arm) will be included in a substudy involving cardiac MRI at baseline and week 48. Twenty non-HIV-infected controls will be included with a single scan to compare with baseline scan data. ETHICS AND DISSEMINATION Result from this study will lead to a better understanding of the association between antiretroviral therapy and the impact on weight and risk of CVD. Findings will be useful for both clinicians and PLWH in the guidance of a more individualised HIV treatment. Results from the main study and the substudies will be submitted for publication in a peer-reviewed journal(s). The AVERTAS study is approved by the Ethics Committee of the Capital Region, Denmark (H-20011433), Danish Medicines Agency (EudraCT no. 2019-004999-19) and Regional Data Protection Centre (P-2020-207).

Evaluation of antiretroviral therapy effect and prognosis between HIV-1 recent and long-term infection based on a rapid recent infection testing algorithm. Front Microbiol 2022; 13:1004960. [PMID: 36483196 PMCID: PMC9722761 DOI: 10.3389/fmicb.2022.1004960] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2022] [Accepted: 10/14/2022] [Indexed: 08/30/2023] Open
Abstract
Early diagnosis of HIV-1 infection and immediate initiation of combination antiretroviral therapy (cART) are important for achieving better virological suppression and quicker immune reconstitution. However, no serological HIV-1 recency testing assay has been approved for clinical use, and the real-world clinical outcomes remain to be explored for the subjects with HIV-1 recent infection (RI) or long-term infection (LI) when antiretroviral therapy is initiated. In this study, a HIV-1 rapid recent-infection testing strip (RRITS) was developed and incorporated into the recent infection testing algorithms (RITAs) to distinguish HIV-1 RI and LI and to assess their clinical outcomes including virological response, the recovery of CD4+ T-cell count and CD4/CD8 ratio and the probability of survival. We found that the concordance between our RRITS and the commercially available LAg-Avidity EIA was 97.13% and 90.63% when detecting the longitudinal and cross-sectional HIV-1 positive samples, respectively. Among the 200 HIV-1 patients analyzed, 22.5% (45/200) of them were RI patients and 77.5% (155/200) were chronically infected and 30% (60/200) of them were AIDS patients. After cART, 4.1% (5/155) of the LI patients showed virological rebound, but none in the RI group. The proportion of CD4+ T-cell count >500 cells/mm3 was significantly higher in RI patients than in LI after 2 years of cART with a hazard ratio (HR) of 2.6 (95% CI: 1.9, 3.6, p < 0.0001) while the probability of CD4/CD8 = 1 was higher in RI than in LI group with a HR of 3.6 (95% CI: 2.2, 5.7, p < 0.0001). Furthermore, the immunological recovery speed was 16 cells/mm3/month for CD4+ T-cell and 0.043/month for the ratio of CD4/CD8 in the RI group, and was bigger in the RI group than in the LI patients (p < 0.05) during the 1st year of cART. The survival probability for LI patients was significantly lower than that for RI patients (p < 0.001). Our results indicated that RRITS combined with RITAs could successfully distinguish HIV-1 RI and LI patients whose clinical outcomes were significantly different after cART. The rapid HIV-1 recency test provides a feasible assay for diagnosing HIV-1 recent infection and a useful tool for predicting the outcomes of HIV-1 patients.

Abstract
Background:
Tenofovir disoproxil fumarate (TDF) is a major antiretroviral therapy for Thai human immunodeficiency virus (HIV) infected adults. TDF is associated with a decrease in renal function. There is limited data about the use of TDF with the incidence and time to renal impairment and chronic kidney disease (CKD) in Thai HIV-infected adults.
Objectives:
To study the association of TDF with the incidence rate and duration of renal impairment and CKD in Thai patients.
Methods:
A retrospective cohort study in Thai naïve HIV-infected adults was conducted to compare the incidence rate and time to renal impairment and CKD in TDF and non-TDF groups. The incidence rate was analyzed by person-time. Time to renal impairment and CKD were analyzed by Kaplan-Meier curves and log-rank tests.
Results:
A total of 1,400 patients were enrolled. The incidence rates of renal impairment in TDF and non-TDF groups were 27.66/1,000 and 5.54/1,000 person-years. The rate ratio was 4.99 (95% confidence interval [CI] 2.66–9.35). The incidence rates of CKD in both groups were not significantly different. Themean difference of eGFR between the TDF and non-TDF groups was 1.92 ml/min/1.73 m2 (p = 0.022). Time to onset of renal impairment between the TDF and non-TDF groups was found to differ by approximately 20 months.
Conclusion:
The incidence rate of renal impairment was about five times higher in the TDF group. A rapid decline of eGFR occurred in the first 2–3 years of treatment. Therefore, the renal function of HIV-infected patients should be monitored so that the severity of renal impairment could be evaluated and CKD could be prevented.

The burden of serious non-AIDS-defining events among admitted cART-naive AIDS patients in China: An observational cohort study. PLoS One 2020; 15:e0243773. [PMID: 33351812 PMCID: PMC7755215 DOI: 10.1371/journal.pone.0243773] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2020] [Accepted: 11/29/2020] [Indexed: 12/17/2022] Open
Abstract
The objective of this study was to elucidate the burden, risk factors, and prognosis of serious non-AIDS-defining events among admitted cART-naive AIDS patients in China. The evaluation of the burden, risk factors and prognosis of serious NADEs was carried out among 1309 cART-naive AIDS patients (median age: 38.2 years, range: 18–78 years) admitted in Beijing Ditan Hospital between January 2009 and December 2018. Among 1309 patients, 143 patients (10.9%) had at least one serious NADEs, including 49 (3.8%) with cerebrovascular diseases, 37 (2.8%) with non-AIDS-defining cancers, 28 (2.1%) with chronic kidney diseases, 26 (2.0%) with cardiovascular diseases, and 18 (1.4%) with liver cirrhosis. Serious NADEs distributed in different age and CD4 levels, especially with age ≥50 years and CD4 ≤350 cells/ul. Other traditional risk factors, including cigarette smoking (OR = 1.9, 95%CI = 1.3–2.8, p = 0.002), hypertension (OR = 2.5, 95%CI = 1.7–3.7, p<0.001), chronic HCV infection (OR = 2.8, 95%CI = 1.4–5.6, p = 0.004), and hypercholesterolemia (OR = 4.1, 95% CI = 1.2–14.1, p = 0.026), were also associated with serious NADEs. Seventeen cases (1.3%) with serious NADEs died among hospitalized cART-naive AIDS patients, and severe pneumonia (HR = 5.5, 95%CI = 1.9–15.9, p<0.001) and AIDS-defining cancers (HR = 3.8, 95%CI = 1.1–13.2, p = 0.038) were identified as risk factors associated with an increased hazard of mortality among these patients with serious NADEs. Serious NADEs also occurred in cART-naive AIDS patients in China with low prevalence. Our results reminded physicians that early screening of serious NADEs, timely intervention of their risk factors, management of severe AIDS-defining events, multi-disciplinary cooperation, and early initiation of cART were essential to reduce the burden of serious NADEs.

Abstract
Background More than 70 million people worldwide are estimated to have hepatitis C virus (HCV) infection. Emerging evidence indicates an association between HCV and atherosclerotic cardiovascular disease. We aimed to determine the association between HCV and cardiovascular disease, and estimate the national, regional, and global burden of cardiovascular disease attributable to HCV. Methods For this systematic review and meta-analysis, we searched MEDLINE, Embase, Ovid Global Health, and Web of Science databases from inception to May 9, 2018, without language restrictions, for longitudinal studies that evaluated the risk ratio (RR) of cardiovascular disease in people with HCV compared with those without HCV. Two investigators independently reviewed and extracted data from published reports. The main outcome was cardiovascular disease, defined as hospital admission with, or mortality from, acute myocardial infarction or stroke. We calculated the pooled RR of cardiovascular disease associated with HCV using a random-effects model. Additionally, we calculated the population attributable fraction and disability-adjusted life-years (DALYs) from HCV-associated cardiovascular disease at the national, regional, and global level. We also used age-stratified and sex-stratified HCV prevalence estimates and cardiovascular DALYs for 100 countries to estimate country-level burden associated with HCV. This study is registered with PROSPERO, number CRD42018091857. Findings Our search identified 16 639 records, of which 36 studies were included for analysis, including 341 739 people with HCV. The pooled RR for cardiovascular disease was 1·28 (95% CI 1·18–1·39). Globally, 1·5 million (95% CI 0·9–2·1) DALYs per year were lost due to HCV-associated cardiovascular disease. Low-income and middle-income countries had the highest disease burden with south Asian, eastern European, north African, and Middle Eastern regions accounting for two-thirds of all HCV-associated cardiovascular DALYs. Interpretation HCV infection is associated with an increased risk of cardiovascular disease. The global burden of cardiovascular disease associated with HCV infection was responsible for 1·5 million DALYs, with the highest burden in low-income and middle-income countries.

Abstract
The incidence of (Human immune deficiency) HIV in India has fallen by 58% since the onset of the HIV epidemic. As of 2016 there are 2.1 million people living in India with HIV and only 49% of the adults with HIV are on ART (1). The HIV infected individuals may require intensive care due to various reasons. This study attempts to look at the outcomes of these patients admitted in the intensive care unit and the predictors of these outcomes.

Abstract
OBJECTIVES Abacavir's potential to cause cardiovascular disease (CVD) among people living with HIV (PLWH) is debated. We conduct a systematic review and meta-analyses to assess CVD risk from recent and cumulative abacavir exposure. METHODS We searched Medline, Embase, Web of Science, abstracts from Conference on Retroviruses and Opportunistic Infections, and International AIDS Society/AIDS Conferences and bibliographies of review articles to identify research studies published through 2018 on CVD risk associated with abacavir exposure among PLWH. Studies assessing risk of CVD associated with recent (exposure within last 6 months) or cumulative abacavir exposure across all age-groups were eligible. Risks were quantified using fixed- and random-effects models. RESULTS Of 378 unique citations, 68 full-text research articles and abstracts were reviewed. Seventeen studies assessed risk of CVD from recent or cumulative abacavir exposure. Summary relative risk (sRR) is increased for recent exposure (n=16 studies, sRR=1.61; 95% confidence interval: 1.48-1.75), higher in antiretroviral-therapy-naive population (n=5, 1.91; 1.48-2.46) and all studies reported RR>1. The sRR for recent exposure was similarly increased for the outcome of acute myocardial infarction, and for studies that adjusted for substance abuse, smoking, prior CVD, traditional CVD risk factors, and CD4 cell-count/HIV viral load. The sRR was increased for cumulative abacavir exposure (per year) (n=4, 1.12; 1.05-1.20) but no increase was seen after adjusting for recent exposure (n=5, 1.00; 0.93-1.08). CONCLUSIONS Our findings suggest an increased risk of CVD from recent abacavir exposure. The risk remained elevated after adjusting for potential confounders. Further investigations are needed to understand CVD risk from cumulative exposure.

Abstract
INTRODUCTION It is unclear whether the treatment of an HIV infection with highly active antiretroviral therapy (HAART) affects intensive care unit (ICU) outcomes. In this paper, we report the results of a systematic review and meta-analysis performed to summarize the effects of HAART on the prognosis of critically ill HIV positive patients. MATERIALS AND METHODS A bibliographic search was performed in 3 databases (PubMed, Web of Science and Scopus) to identify articles that investigated the use of HAART during ICU admissions for short- and long-term mortality or survival. Eligible articles were selected in a staged process and were independently assessed by two investigators. The methodological quality of the selected articles was evaluated using the Methodological Index for Non-Randomized Studies (MINORS) tool. RESULTS Twelve articles met the systematic review inclusion criteria and examined short-term mortality. Six of them also examined long-term mortality (≥90 days) after ICU discharge. The short-term mortality meta-analysis showed a significant beneficial effect of initiating or maintaining HAART during the ICU stay (random effects odds ratio 0.53, p = 0.02). The data analysis of long-term outcomes also suggested a reduced mortality when HAART was used, but the effect of HAART on long-term mortality of HIV positive critically ill patients remains uncertain. CONCLUSIONS This meta-analysis suggests improved survival rates for HIV positive patients who were treated with HAART during their ICU admission.

Abstract
Liver disease is one of the main contributors to the increased levels of morbidity and mortality seen in the HIV-1-infected, ART-treated population. Circulating miRNAs, particularly those located inside extracellular vesicles, are seen as promising biomarkers for a number of human disease conditions, including liver-related diseases. Here, we show that serum levels of miR-122 and miR-200a are greater in HIV/HCV co-infected individuals compared to HIV-1 mono-infected individuals. We also show that miR-122 and miR-200a are elevated in ART-treated, HIV-1-infected individuals prior to the development of fatal liver disease, suggesting that these miRNA may have some potential clinical utility as biomarkers. While this study is hypothesis generating, it shows clearly that both miR-122 and miR-200a are promising novel biomarkers for liver disease in the ART-treated, HIV-1-infected population.

A decade of HAART in Latin America: Long term outcomes among the first wave of HIV patients to receive combination therapy. PLoS One 2017; 12:e0179769. [PMID: 28651014 PMCID: PMC5484471 DOI: 10.1371/journal.pone.0179769] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2016] [Accepted: 06/02/2017] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND In Latin America, the first wave of HIV-infected patients initiated highly active antiretroviral therapy (HAART) 10 or more years ago. Characterizing their treatment experience and corresponding outcomes across a decade of HAART may yield insights relevant to the ongoing care of such patients and those initiating HAART more recently in similar clinical settings. METHODS This retrospective study included adults initiating HAART before 2004 at 8 sites in Argentina, Brazil, Chile, Haiti, Honduras, and Mexico. Patient status (in care, dead, or lost to follow-up [LTFU]) was assessed at 6-month intervals for 10 years, along with CD4 count and HIV-1 viral load (VL) for patients in care. RESULTS 4,975 patients (66% male) started HAART prior to 2004; 45% were not antiretroviral-naïve. At 1, 5, and 10 years, rates of mortality were 4.2%, 9.0%, and 13.6% respectively. LTFU rates for the same periods were 2.4%, 10.9%, and 24.2%. Among patients remaining in care at 10 years, 84.4% were estimated to have VL≤400 copies/mL (Haiti excluded) and median baseline CD4 increased from 158 to 525 cells/mm3. Only 11.4% of all patients remained on their first regimen, 12.6% were on their second, 11.5% were on their third, and 23.0% were on their fourth or subsequent regimen. Outcomes were generally better for patients who were not antiretroviral-naïve, except for viral suppression. Heterogeneity among sites was substantial. CONCLUSIONS Despite advanced disease and predominant use of older antiretrovirals, a large percentage of early HAART initiators in this Latin American cohort were alive and in care with sustained virologic suppression and progressive immune recovery after 10 years.

Abstract
The advances in management of patients with acquired immunodeficiency syndrome (AIDS) with highly effective anti-retroviral therapy (HAART) have resulted in increased longevity of patients with human immunodeficiency virus (HIV) infection. AIDS-related illnesses now account for less than 50 % of the deaths, and liver diseases have emerged as the leading cause of death in patients with HIV infection. Chronic viral hepatitis, drug-related hepatotoxicity, non-alcoholic fatty liver disease, and opportunistic infections are the common liver diseases that are seen in HIV-infected individuals. Because of the shared routes of transmission, co-infections with hepatitis B virus (HBV) and hepatitis C virus (HCV) are very common in HIV-infected persons. Hepatitis C is the most common viral hepatitis seen in HIV-infected patients. With the availability of directly acting agents, treatment outcome of HCV is comparable to that seen in non HIV-infected patients. Careful monitoring is required for drug interactions and drug-induced hepatotoxicity and modification of drugs should be done where necessary. The results of liver transplantation in select HIV-infected patients can be comparable with those of HIV-negative patients.

Abstract
BACKGROUND Breast cancer in HIV-positive patients has been reported in some retrospective studies and outcomes are mixed. This paper reviews the experience of an urban HIV outpatient clinic serving with patients infected with HIV infection. METHODS A retrospective study from 2002-2010 was conducted on a total of 2,060 patients with HIV (1361 M, 699 F) who were evaluated and treated in the HIV Outpatient Program clinic at the Medical Center of Louisiana in New Orleans as of March 2010. RESULTS A total of 5 patients were identified. Their average age was 45.6, and 100% were African American. Their average CD4 counts before and after diagnosis of breast cancer were 333 cells/mm(3) and 353.3 cells/mL, respectively. The average number of years with HIV infection was 8.8. The average body mass index (BMI) was 24.8. Eighty (80%) were intraductal carcinoma and 20% were inflammatory cancers. The average survival time for all patients was 5.2 years. DISCUSSION The frequency of breast cancer in our population is low. We did not find any relationship among immunosuppression, obesity, and development of breast cancer. More studies are needed to elucidate the impact of HIV infection in the biology of breast cancer.

Abstract
INTRODUCTION Benefits and harms of tenofovir disoproxil fumarate (TDF) in HIV-infected, antiretroviral treatment (ART)-naïve patients of any age have not been systematically reviewed since recent milestone trials were published. METHODS We searched MEDLINE, EMBASE, CENTRAL, SCI, LILACS, WHO GHL, and ClinicalTrials.gov for randomized controlled trials (RCTs) comparing TDF-based treatments with any other ART-regimen (last search 01/2015). Trial characteristics and results were extracted, risks of bias systematically assessed, and treatment effects synthesized in meta-analyses using random-effects models. RESULTS We included 22 RCTs (8297 patients). We found no differences between groups for mortality, AIDS, fractures, CD4 cell count, and virological failure; and inconclusive information due to inadequate reporting for cardiovascular events, renal failure, proteinuria, rash, and quality of life. Tenofovir disoproxil fumarate-based regimens significantly reduced total cholesterol (mean difference -18.42 mg/dl; 95% confidence interval [CI] -22.80 to -14.0), LDL-cholesterol (-9.53 mg/dl; -12.16 to -6.89), HDL-cholesterol (-2.97 mg/dl; -4.41 to -1.53), and triglycerides (-29.77 mg/dl; -38.61 to -20.92), bone mineral density (BMD) (hip: -1.41%; -1.87 to -0.94), and glomerular filtration rate (eGFR) (-3.47 ml/minute; -5.89 to -1.06) over 48 weeks of follow-up. Effects were similar in trials comparing fixed-dose TDF/FTC-based regimens with ABC/3TC-based regimens. We found no influence of baseline viral load on virological failure. DISCUSSION Moderate-quality evidence suggests similar effects of TDF-based treatment regimens and other ART on virological failure. Tenofovir disoproxil fumarate-based regimens are associated with a more favorable lipid profile, but with increased risk of reduced BMD and eGFR. Improved reporting quality is vital to allow assessment of clinical outcomes in future trials.

Abstract
Improved understanding of cholesterol levels in HIV- and hepatitis C virus (HCV)-infected persons in Argentina will guide optimal antiretroviral therapy. The authors conducted a cross-sectional study in Argentina to describe associations between HIV, HCV, and cholesterol. Of the 202 participants, 21 were HIV infected, 15 were HCV infected, 46 were HIV/HCV coinfected, and 120 were HIV/HCV uninfected. HIV/HCV-uninfected participants had the highest total cholesterol (TC) and low-density lipoprotein (LDL) levels. Multivariate modeling revealed that HIV/HCV-coinfected patients had the lowest TC levels (-28.7 mg/dL, P < .001) compared to the HIV/HCV-uninfected reference group. Hepatitis C virus and HIV/HCV coinfection were associated with lower LDL levels (-21.4 mg/dL, P = .001 and -20.3 mg/dL, P < .0001, respectively). HIV and HIV/HCV coinfection, but not HCV alone, were associated with lower high-density lipoprotein levels (-9.1 mg/dL, P = .0008 and -6.8 mg/dL, P = .0006, respectively). Further study is needed to examine whether the more favorable lipid profile observed in HIV/HCV-coinfected persons is associated with a reduction in cardiovascular risk.

Abstract
BACKGROUND People living with HIV-infection (PLWH) have higher prevalence and earlier onset of cardiovascular disease (CVD), compared to uninfected populations. It is unclear how alcohol consumption is related to CVD among PLWH. OBJECTIVES To summarize the current literature and strength of evidence regarding alcohol consumption as a risk factor for CVD among PLWH, to generate summary estimates for the effect of alcohol consumption on CVD outcomes, and to make recommendations for clinical practice and future research based on the findings and limitations of existing studies. METHODS A systematic review was conducted using Pubmed/Medline to identify relevant peer-reviewed articles published between 1 January 1999 and 1 January 2014. After critical review of the literature, 13 studies were identified. Risk ratios were extracted or calculated and sample size weighted summary estimates were calculated. RESULTS The prevalence of a CVD diagnosis or event ranged from 5.7-24.0%. The weighted pooled crude effect sizes were 1.75 (95% CI 1.06, 3.17) for general and 1.78 (95% CI 1.09, 2.93) for heavy alcohol use on CVD. The pooled adjusted effect size was 1.37 (95% CI 1.02, 1.84) for heavy alcohol use on CVD. Pooled estimates differed by CVD outcome and alcohol measure; alcohol consumption was most significant for cerebral/ischemic events. CONCLUSION HIV clinicians should consider risk factors that are not included in the traditional risk factor framework, particularly heavy alcohol consumption. Neglect of this risk factor may lead to underestimation of risk, and thus under-treatment among PLWH.

Abstract
BACKGROUND To characterize the association of antiretroviral drug combinations on risk of cardiovascular events. METHODS Certain antiretroviral medications for human immunodeficiency virus (HIV) have been implicated in increasing risk of cardiovascular disease. However, antiretroviral drugs are typically prescribed in combination. We characterized the association of current exposure to antiretroviral drug combinations on risk of cardiovascular events including myocardial infarction, stroke, percutaneous coronary intervention, and coronary artery bypass surgery. We used the Veterans Health Administration Clinical Case Registry to analyze data from 24 510 patients infected with HIV from January 1996 through December 2009. We assessed the association of current exposure to 15 antiretroviral drugs and 23 prespecified combinations of agents on the risk of cardiovascular event by using marginal structural models and Cox models extended to accommodate time-dependent variables. RESULTS Over 164 059 person-years of follow-up, 934 patients had a cardiovascular event. Current exposure to abacavir, efavirenz, lamivudine, and zidovudine was significantly associated with increased risk of cardiovascular event, with odds ratios ranging from 1.40 to 1.53. Five combinations were significantly associated with increased risk of cardiovascular event, all of which involved lamivudine. One of these-efavirenz, lamivudine, and zidovudine-was the second most commonly used combination and was associated with a risk of cardiovascular event that is 1.60 times that of patients not currently exposed to the combination (odds ratio = 1.60, 95% confidence interval, 1.25-2.04). CONCLUSIONS In the VA cohort, exposure to both individual drugs and drug combinations was associated with modestly increased risk of a cardiovascular event.

Abstract
BACKGROUND Short-term morbidity and mortality rates for HIV positive soldiers in the South African National Defence Force (SANDF) would inform decisions about deployment and HIV disease management. Risks were determined according to the latest CD4+ cell count and use of antiretroviral therapy (ART) for HIV positive individuals in the SANDF and their dependents. METHODS AND FINDINGS A total of 7,114 participants were enrolled and followed for mortality over a median of 4.7 years (IQR: 1.9, 7.1 years). For a planned subset (5,976), progression of disease (POD) and grade 4, potentially life-threatening events were also ascertained. CD4+ count and viral load were measured every 3 to 6 months. Poisson regression was used to compare event rates by latest CD4+ count (<50, 50-99, 100-199, 200-349, 350-499, 500+) with a focus on upper three strata, and to estimate relative risks (RRs) (ART/no ART). Median entry CD4+ was 207 cells/mm3. During follow-up over 70% were prescribed ART. Over follow-up 1,226 participants died; rates ranged from 57.6 (< 50 cells) to 0.8 (500+ cells) per 100 person years (py). Compared to those with latest CD4+ 200-349 (2.2/100 py), death rates were significantly lower (p<0.001), as expected, for those with 350-499 (0.9/100 py) and with 500+ cells (0.8/100 py). The composite outcome of death, POD or grade 4 events occurred in 2,302 participants (4,045 events); rates were similar in higher CD4+ count strata (9.4 for 350-499 and 7.9 for 500+ cells) and lower than those with counts 200-349 cells (13.5) (p<0.001). For those with latest CD4+ 350+ cells, 63% of the composite outcomes (680 of 1,074) were grade 4 events. CONCLUSION Rates of morbidity and mortality are lowest among those with CD4+ count of 350 or higher and rates do not differ for those with counts of 350-499 versus 500+ cells. Grade 4 events are the predominant morbidity for participants with CD4+ counts of 350+ cells.

Abstract
OBJECTIVE To alert the pediatrician who is following up HIV-infected patients about the possibility of non-cirrhotic portal hypertension (NCPH) in this period of life, in order to avoid the catastrophic consequences of this disease as bleeding esophageal varices. CASE DESCRIPTION A 13 years old HIV-infected patient by vertical route was receiving didanosine (ddI) for 12 years. Although the HIV viral load had been undetectable for 12 years, this patient showed gradual decrease of CD4+ T cells, prolonged thrombocytopenia and high alkaline phosphatase. Physical examination detected splenomegaly, which triggered the investigation that led to the diagnosis of severe liver fibrosis by transient elastography, probably due to hepatic toxicity by prolonged use of ddI. COMMENTS This is the first case of NCPH in HIV-infected adolescent described in Brazil. Although, the NCPH is a rare disease entity in seropositive patients in the pediatric age group, it should be investigated in patients on long-term ddI or presenting clinical and laboratories indicators of portal hypertension, as splenomegaly, thrombocytopenia and increased alkaline phosphatase.

Abstract
Nearly 2 million people are infected with human immunodeficiency virus (HIV) in Latin America. However, information regarding population-scale outcomes from a regional perspective is scarce. We aimed to describe the baseline characteristics and therapeutic outcomes of newly-treated individuals with HIV infection in Latin America. A Retrospective cohort study was undertaken. The primary explanatory variable was combination antiretroviral therapy based on either a protease inhibitor (PI) or a non-nucleoside reverse transcriptase inhibitor (NNRTI). The main outcome was defined as the composite of all-cause mortality and the occurrence of an AIDS-defining clinical event or a serious non-AIDS-defining event during the first year of therapy. The secondary outcomes included the time to a change in treatment strategy. All analyses were performed according to the intention to treat principle. A total of 937 treatment-naive patients from four participating countries were included (228 patients with PI therapy and 709 with NNRTI-based treatment). At the time of treatment initiation, the patients had a mean age of 37 (SD: 10) years and a median CD4 + T-cell count of 133 cells/mm(3) (interquartile range: 47.5-216.0). Patients receiving PI-based regimens had a significantly lower CD4 + count, a higher AIDS prevalence at baseline and a shorter time from HIV diagnosis until the initiation of treatment. There was no difference in the hazard ratio for the primary outcome between groups. The only covariates associated with the latter were CD4 + cell count at baseline, study site and age. The estimated hazard ratio for the time to a change in treatment (NNRTI vs PI) was 0.61 (95% CI 0.47-0.80, p < 0.01). This study concluded that patients living with HIV in Latin America present with similar clinical outcomes regardless of the choice of initial therapy. Patients treated with PIs are more likely to require a treatment change during the first year of follow up.

[PMID: 25340766 PMCID: PMC4207829 DOI: 10.1371/journal.pone.0111400] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2014] [Accepted: 10/01/2014] [Indexed: 11/18/2022] Open
Abstract
Combination antiretroviral therapy (cART) has been widely available in Ghana since 2004. The aim of this cohort study was to assess the incidences of death, AIDS-defining events and non-AIDS defining events and associated risk factors amongst patients initiating cART in a large treatment centre. Clinical and laboratory data were extracted from clinic and hospital case notes for patients initiating cART between 2004 and 2010 and clinical events graded according to recognised definitions for AIDS, non-AIDS events (NADE) and death, with additional events not included in such definitions such as malaria also included. The cumulative incidence of events was calculated using Kaplan Meier analysis, and association of risk factors with events by Cox proportional hazards regression. Data were closed for analysis on 31st December, 2011 after a median follow-up of 30 months (range, 0-90 months). Amongst 4,039 patients starting cART at a median CD4 count of 133 cells/mm3, there were 324 (8%) confirmed deaths, with an event rate of 28.83 (95% CI 25.78-32.15) deaths per 1000-person follow-up years; the commonest established causes were pulmonary TB and gastroenteritis. There were 681 AIDS-defining events (60.60 [56.14-65.33] per 1000 person years) with pulmonary TB and chronic diarrhoea being the most frequent causes. Forty-one NADEs were recorded (3.64 [2.61-4.95] per 1000 person years), of which hepatic and cardiovascular events were most common. Other common events recorded outside these definitions included malaria (746 events) and respiratory tract infections (666 events). Overall 24% of patients were lost-to-follow-up. Alongside expected risk factors, stavudine use was associated with AIDS [adjusted HR of 1.08 (0.90-1.30)] and death (adjusted HR of 1.60 [1.21-2.11]). Whilst frequency of AIDS and deaths in this cohort were similar to those described in other sub-Saharan African cohorts, rates of NADEs were lower and far exceeded by events such as malaria and respiratory tract infections.

Abstract
The life expectancy of people living with HIV has dramatically improved with the much increased access to antiretroviral therapy. Consequently, a larger number of people living with HIV are living longer and facing the increased burden of noncommunicable diseases (NCDs). NCDs and HIV infection share common epidemiologic and sociodemographic characteristics that influence their outcomes, which may be difficult to address in the relatively weak health systems of the region. Data on the prevalence and interactions of NCDs and HIV in Latin American countries remain very limited, which hinders their governments' ability to make informed decisions about health care policies. Therefore, there is an urgent need to develop a research agenda that will be the basis for an integrated and comprehensive health care approach to HIV and NCD comorbidities in Latin America.

AIDS and non-AIDS severe morbidity associated with hospitalizations among HIV-infected patients in two regions with universal access to care and antiretroviral therapy, France and Brazil, 2000-2008: hospital-based cohort studies. BMC Infect Dis 2014; 14:278. [PMID: 24885790 PMCID: PMC4032588 DOI: 10.1186/1471-2334-14-278] [Citation(s) in RCA: 26] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2014] [Accepted: 05/06/2014] [Indexed: 11/26/2022] Open
Abstract
Background In high-income settings, the spectrum of morbidity and mortality experienced by Human Immunodeficiency Virus (HIV)-infected individuals receiving combination antiretroviral therapy (cART) has switched from predominantly AIDS-related to non-AIDS-related conditions. In the context of universal access to care, we evaluated whether that shift would apply in Brazil, a middle-income country with universal access to treatment, as compared to France. Methods Two hospital-based cohorts of HIV-infected individuals were used for this analysis: the ANRS CO3 Aquitaine Cohort in South Western France and the Evandro Chagas Research Institute (IPEC) Cohort of the Oswaldo Cruz Foundation in Rio de Janeiro, Brazil. Severe morbid events (AIDS- and non-AIDS-related) were defined as all clinical diagnoses associated with a hospitalization of ≥48 hours. Trends in the incidence rate of events and their determinants were estimated while adjusting for within-subject correlation using generalized estimating equations models with an auto-regressive correlation structure and robust standard errors. Result Between January 2000 and December 2008, 7812 adult patients were followed for a total of 41,668 person-years (PY) of follow-up. Throughout the study period, 90% of the patients were treated with cART. The annual incidence rate of AIDS and non-AIDS events, and of deaths significantly decreased over the years, from 6.2, 21.1, and 1.9 AIDS, non-AIDS events, and deaths per 100 PY in 2000 to 4.3, 14.9, and 1.5/100 PY in 2008. The annual incidence rates of non-AIDS events surpassed that of AIDS-events during the entire study period. High CD4 cell counts were associated with a lower incidence rate of AIDS and non-AIDS events as well as with lower rates of specific non-AIDS events, such as bacterial, hepatic, viral, neurological, and cardiovascular conditions. Adjusted analysis showed that severe morbidity was associated with lower CD4 counts and higher plasma HIV RNAs but not with setting (IPEC versus Aquitaine). Conclusions As information on severe morbidities for HIV-infected patients remain scarce, data on hospitalizations are valuable to identify priorities for case management and to improve the quality of life of patients with a chronic disease requiring life-long treatment. Immune restoration is highly effective in reducing AIDS and non-AIDS severe morbid events irrespective of the setting.

Abstract
Background The HIV-Brazil Cohort Study was established to analyze the effectiveness of combination antiretroviral therapy (cART) and the impact of this treatment on morbidity, quality of life (QOL) and mortality. The study design, patients’ profiles and characteristics of cART initiation between 2003 and 2010 were described. Methodology/Principal Findings Since 2003, the HIV-Brazil Cohort has been following HIV-infected adults receiving cART at 26 public health care facilities, using routine clinical care data and self-reported QOL questionnaires. When not otherwise available, data are obtained from national information systems. The main outcomes of interest are diseases related or unrelated to HIV; suppression of viral replication; adverse events; virological, clinical and immunological failures; changes in the cART; and mortality. For the 5,061 patients who started cART between 2003 and 2010, the median follow-up time was 4.1 years (IQR 2.2–5.9 years) with an 83.4% retention rate. Patient profiles were characterized by a predominance of men (male/female ratio 1.7∶1), with a mean age of 36.9 years (SD 9.9 years); 55.2% had been infected with HIV via heterosexual contact. The majority of patients (53.4%) initiated cART with a CD4+ T-cell count ≤200 cells/mm3. The medications most often used in the various treatment regimens were efavirenz (59.7%) and lopinavir/ritonavir (18.2%). The proportion of individuals achieving viral suppression within the first 12 months of cART use was 77.4% (95% CI 76.1–78.6). Nearly half (45.4%) of the patients presented HIV-related clinical manifestations after starting cART, and the AIDS mortality rate was 13.9 per 1,000 person-years. Conclusions/Significance Results from cART use in the daily practice of health services remain relatively unknown in low- and middle-income countries, and studies with the characteristics of the HIV-Brazil Cohort contribute to minimizing these shortcomings, given its scope and patient profile, which is similar to that of the AIDS epidemic in the country.

Abstract
BACKGROUND Use of antiretroviral treatment for HIV-1 infection has decreased AIDS-related morbidity and mortality and prevents sexual transmission of HIV-1. However, the best time to initiate antiretroviral treatment to reduce progression of HIV-1 infection or non-AIDS clinical events is unknown. We reported previously that early antiretroviral treatment reduced HIV-1 transmission by 96%. We aimed to compare the effects of early and delayed initiation of antiretroviral treatment on clinical outcomes. METHODS The HPTN 052 trial is a randomised controlled trial done at 13 sites in nine countries. We enrolled HIV-1-serodiscordant couples to the study and randomly allocated them to either early or delayed antiretroviral treatment by use of permuted block randomisation, stratified by site. Random assignment was unblinded. The HIV-1-infected member of every couple initiated antiretroviral treatment either on entry into the study (early treatment group) or after a decline in CD4 count or with onset of an AIDS-related illness (delayed treatment group). Primary events were AIDS clinical events (WHO stage 4 HIV-1 disease, tuberculosis, and severe bacterial infections) and the following serious medical conditions unrelated to AIDS: serious cardiovascular or vascular disease, serious liver disease, end-stage renal disease, new-onset diabetes mellitus, and non-AIDS malignant disease. Analysis was by intention-to-treat. This trial is registered with ClinicalTrials.gov, number NCT00074581. FINDINGS 1763 people with HIV-1 infection and a serodiscordant partner were enrolled in the study; 886 were assigned early antiretroviral treatment and 877 to the delayed treatment group (two individuals were excluded from this group after randomisation). Median CD4 counts at randomisation were 442 (IQR 373-522) cells per μL in patients assigned to the early treatment group and 428 (357-522) cells per μL in those allocated delayed antiretroviral treatment. In the delayed group, antiretroviral treatment was initiated at a median CD4 count of 230 (IQR 197-249) cells per μL. Primary clinical events were reported in 57 individuals assigned to early treatment initiation versus 77 people allocated to delayed antiretroviral treatment (hazard ratio 0·73, 95% CI 0·52-1·03; p=0·074). New-onset AIDS events were recorded in 40 participants assigned to early antiretroviral treatment versus 61 allocated delayed initiation (0·64, 0·43-0·96; p=0·031), tuberculosis developed in 17 versus 34 patients, respectively (0·49, 0·28-0·89, p=0·018), and primary non-AIDS events were rare (12 in the early group vs nine with delayed treatment). In total, 498 primary and secondary outcomes occurred in the early treatment group (incidence 24·9 per 100 person-years, 95% CI 22·5-27·5) versus 585 in the delayed treatment group (29·2 per 100 person-years, 26·5-32·1; p=0·025). 26 people died, 11 who were allocated to early antiretroviral treatment and 15 who were assigned to the delayed treatment group. INTERPRETATION Early initiation of antiretroviral treatment delayed the time to AIDS events and decreased the incidence of primary and secondary outcomes. The clinical benefits recorded, combined with the striking reduction in HIV-1 transmission risk previously reported, provides strong support for earlier initiation of antiretroviral treatment.

Abstract
OBJECTIVE Formulae used to estimate glomerular filtration rate (GFR) underestimate higher GFRs and have not been well-studied in HIV-infected (HIV(+)) people; we evaluated the relationships of HIV infection and known or potential risk factors for kidney disease with directly measured GFR and the presence of chronic kidney disease (CKD). DESIGN Cross-sectional measurement of iohexol-based GFR (iGFR) in HIV(+) men (n = 455) receiving antiretroviral therapy, and HIV-uninfected (HIV(-)) men (n = 258) in the Multicenter AIDS Cohort Study. METHODS iGFR was calculated from disappearance of infused iohexol from plasma. Determinants of GFR and the presence of CKD were compared using iGFR and GFR estimated by the CKD-Epi equation (eGFR). RESULTS Median iGFR was higher among HIV(+) than HIV(-) men (109 vs. 106 ml/min/1.73 m(2), respectively, p = .046), and was 7 ml/min higher than median eGFR. Mean iGFR was lower in men who were older, had chronic hepatitis C virus (HCV) infection, or had a history of AIDS. Low iGFR (≤90 ml/min/1.73 m(2)) was associated with these factors and with black race. Other than age, factors associated with low iGFR were not observed with low eGFR. CKD was more common in HIV(+) than HIV(-) men; predictors of CKD were similar using iGFR and eGFR. CONCLUSIONS iGFR was higher than eGFR in this population of HIV-infected and -uninfected men who have sex with men. Presence of CKD was predicted equally well by iGFR and eGFR, but associations of chronic HCV infection and history of clinically-defined AIDS with mildly decreased GFR were seen only with iGFR.

Abstract
BACKGROUND Reliable information on severe morbidity is essential for identifying priorities for case management and to guide resource allocation within the health sector. METHODS This study describes overall, AIDS- and non-AIDS-related severe morbidity as well as mortality and its determinants in an urban cohort of HIV-infected individuals from a public healthcare institution, the Evandro Chagas Research Institute (IPEC) of the Oswaldo Cruz Foundation, Rio de Janeiro, Brazil. Severe morbid events were defined as all clinical diagnoses listed in hospitalization discharge records; all diagnoses were checked and validated. Generalized estimating equation models were used to estimate incidence rates while adjusting for within-subject correlation. RESULTS Between 2000 and 2010, 3,537 patients were followed for a total of 16,960 person-years (PY) of follow-up. Over the years, annual incidence rate of severe morbid events, AIDS-related events, non-AIDS-related events, and deaths significantly decreased from, respectively, 36.6, 12.9, 23.7 and 3.2 per 100 PY in 2000 to 25.3, 7.9, 17.4 and 1.9 per 100 PY in 2010. Patients' immunological profiles significantly improved with time; 84% of the patients used combination antiretroviral therapy (cART) per year. Immunodeficiency was associated with a higher incidence rate of AIDS- and non-AIDS-related events as well as with the incidence rate of specific non-AIDS events (bacterial infections, toxicities, cardiovascular, renal and respiratory diseases). CONCLUSIONS Our results show that in a middle income country with access to cART, non-AIDS-related events represent an important cause of severe morbidity alongside a still high incidence rate of AIDS-related events.

Abstract
Despite the major advances in the management of HIV infection, HIV-infected patients still have greater morbidity and mortality than the general population. Serious non-AIDS events (SNAEs), including non-AIDS malignancies, cardiovascular events, renal and hepatic disease, bone disorders and neurocognitive impairment, have become the major causes of morbidity and mortality in the antiretroviral therapy (ART) era. SNAEs occur at the rate of 1 to 2 per 100 person-years of follow-up. The pathogenesis of SNAEs is multifactorial and includes the direct effect of HIV and associated immunodeficiency, underlying co-infections and co-morbidities, immune activation with associated inflammation and coagulopathy as well as ART toxicities. A number of novel strategies such as ART intensification, treatment of co-infection, the use of anti-inflammatory drugs and agents that reduce microbial translocation are currently being examined for their potential effects in reducing immune activation and SNAEs. However, currently, initiation of ART before advanced immunodeficiency, smoking cessation, optimisation of cardiovascular risk factors and treatment of HCV infection are most strongly linked with reduced risk of SNAEs or mortality. Clinicians should therefore focus their attention on addressing these issues prior to the availability of further data.

Abstract
The introduction of highly active antiretroviral therapy during the 1990s was crucial to the decline in the rates of morbidity and death related to the acquired immunodeficiency syndrome (AIDS) and turned human immunodeficiency virus (HIV) infection into a chronic condition. Consequently, the HIV/AIDS population is becoming older. The aim of this study was to describe the immunological, clinical and comorbidity profile of an urban cohort of patients with HIV/AIDS followed up at Instituto de Pesquisa Clinica Evandro Chagas, Oswaldo Cruz Foundation in Rio de Janeiro, Brazil. Retrospective data from 2307 patients during January 1st, 2008 and December 31st, 2008 were collected. For continuous variables, Cuzick's non-parametric test was used. For categorical variables, the Cochran–Armitage non-parametric test for tendency was used. For all tests, the threshold for statistical significance was set at 5%. In 2008, 1023 (44.3%), 823 (35.7%), 352 (15.3%) and 109 (4.7%) were aged 18–39, 40–49, 50–59 and ≥60 years-old, respectively. Older and elderly patients (≥40 years) were more likely to have viral suppression than younger patients (18–39 years) (p < 0.001). No significant difference in the latest CD4+ T lymphocyte count in the different age strata was observed, although elderly patients (≥ 50 years) had lower CD4+ T lymphocyte nadir (p < 0.02). The number of comorbidities increased with age and the same pattern was observed for the majority of the comorbidities, including diabetes mellitus, dyslipidemia, hypertension, cardiovascular diseases, erectile dysfunction, HCV, renal dysfunction and also for non-AIDS-related cancers (p < 0.001). With the survival increase associated to successful antiretroviral therapy and with the increasing new infections among elderly group, the burden associated to the diagnosis and treatment of the non-AIDS related HIV comorbidities will grow. Longitudinal studies on the impact of aging on the HIV/AIDS population are still necessary, especially in resource-limited countries.

Abstract
Background Recent studies suggest certain antiretroviral therapy (ART) drugs are associated with increases in cardiovascular disease. Purpose We performed a systematic review and meta-analysis to summarize the available evidence, with the goal of elucidating whether specific ART drugs are associated with an increased risk of myocardial infarction (MI). Data Sources We searched Medline, Web of Science, the Cochrane Library, and abstract archives from the Conference on Retroviruses and Opportunistic Infections and International AIDS Society up to June 2011 to identify published articles and abstracts. Study Selection Eligible studies were comparative and included MI, strokes, or other cardiovascular events as outcomes. Data Extraction Eligibility screening, data extraction, and quality assessment were performed independently by two investigators. Data Synthesis Random effects methods and Fisher’s combined probability test were used to summarize evidence. Findings Twenty-seven studies met inclusion criteria, with 8 contributing to a formal meta-analysis. Findings based on two observational studies indicated an increase in risk of MI for patients recently exposed (usually defined as within last 6 months) to abacavir (RR 1.92, 95% CI 1.51–2.42) and protease inhibitors (PI) (RR 2.13, 95% CI 1.06–4.28). Our analysis also suggested an increased risk associated with each additional year of exposure to indinavir (RR 1.11, 95% CI 1.05–1.17) and lopinavir (RR 1.22, 95% CI 1.01–1.47). Our findings of increased cardiovascular risk from abacavir and PIs were in contrast to four published meta-analyses based on secondary analyses of randomized controlled trials, which found no increased risk from cardiovascular disease. Conclusion Although observational studies implicated specific drugs, the evidence is mixed. Further, meta-analyses of randomized trials did not find increased risk from abacavir and PIs. Our findings that implicate specific ARTs in the observational setting provide sufficient evidence to warrant further investigation of this relationship in studies designed for that purpose.

Abstract
BACKGROUND Non-AIDS-defining cancers in HIV-infected patients in the highly active antiretroviral therapy era have increased. To our knowledge a comprehensive review of non-AIDS-related malignancies in New Orleans has not yet been conducted. METHODS Databases from main institutions in New Orleans were queried retrospectively for the years 2001 to 2011. The International Classification of Diseases, Ninth Revision codes were used to search for HIV infection and cancer comorbidity. RESULTS A total of 16 patients were diagnosed with lung cancer (mean age 50 years) with 81% of the patients presenting with advanced stages. In all, 20 (mean age 47 years) were diagnosed with anal cancer, and 35% presented in late stages. In all, 14 patients (mean age 42 years) were diagnosed with Hodgkin Lymphoma, and 64% were diagnosed at late stage. A total of 5 women (mean age 44 years) were diagnosed with breast cancer with 40% of them presenting at late stage. CONCLUSION Malignancies were diagnosed at late stages in the majority of the cases, presented with worse outcomes, and had higher recurrence rates. The role of HIV and other viruses (Epstein Barr virus, human papillomavirus) and the potential mechanisms or pathways of oncogene activation also need to be clarified.

Abstract
BACKGROUND The relationship between the timing of the initiation of antiretroviral therapy (ART) after infection with human immunodeficiency virus type 1 (HIV-1) and the recovery of CD4+ T-cell counts is unknown. METHODS In a prospective, observational cohort of persons with acute or early HIV-1 infection, we determined the trajectory of CD4+ counts over a 48-month period in partially overlapping study sets: study set 1 included 384 participants during the time window in which they were not receiving ART and study set 2 included 213 participants who received ART soon after study entry or sometime thereafter and had a suppressed plasma HIV viral load. We investigated the likelihood and rate of CD4+ T-cell recovery to 900 or more cells per cubic millimeter within 48 months while the participants were receiving viral-load-suppressive ART. RESULTS Among the participants who were not receiving ART, CD4+ counts increased spontaneously, soon after HIV-1 infection, from the level at study entry (median, 495 cells per cubic millimeter; interquartile range, 383 to 622), reached a peak value (median, 763 cells per cubic millimeter; interquartile range, 573 to 987) within approximately 4 months after the estimated date of infection, and declined progressively thereafter. Recovery of CD4+ counts to 900 or more cells per cubic millimeter was seen in approximately 64% of the participants who initiated ART earlier (≤4 months after the estimated date of HIV infection) as compared with approximately 34% of participants who initiated ART later (>4 months) (P<0.001). After adjustment for whether ART was initiated when the CD4+ count was 500 or more cells per cubic millimeter or less than 500 cells per cubic millimeter, the likelihood that the count would increase to 900 or more cells per cubic millimeter was lower by 65% (odds ratio, 0.35), and the rate of recovery was slower by 56% (rate ratio, 0.44), if ART was initiated later rather than earlier. There was no association between the plasma HIV RNA level at the time of initiation of ART and CD4+ T-cell recovery. CONCLUSIONS A transient, spontaneous restoration of CD4+ T-cell counts occurs in the 4-month time window after HIV-1 infection. Initiation of ART during this period is associated with an enhanced likelihood of recovery of CD4+ counts. (Funded by the National Institute of Allergy and Infectious Diseases and others.).

Abstract
Liver disease in human immunodeficiency virus (HIV)-infected individuals encompasses the spectrum from abnormal liver function tests, liver decompensation, with and without evidence of cirrhosis on biopsy, to non-alcoholic liver disease and its more severe form, non-alcoholic steatohepatitis and hepatocellular cancer. HIV can infect multiple cells in the liver, leading to enhanced intrahepatic apoptosis, activation and fibrosis. HIV can also alter gastro-intestinal tract permeability, leading to increased levels of circulating lipopolysaccharide that may have an impact on liver function. This review focuses on recent changes in the epidemiology, pathogenesis and clinical presentation of liver disease in HIV-infected patients, in the absence of co-infection with hepatitis B virus or hepatitis C virus, with a specific focus on issues relevant to low and middle income countries.

Abstract
PURPOSE OF REVIEW Highly active antiretroviral therapy (HAART) has resulted in a marked decrease in AIDS-related conditions and death. With improved survival, cardiovascular disease, hepatic, renal disease, and non-AIDS-related cancers represent an increasing burden for HIV-infected individuals. RECENT FINDINGS HIV-associated nephropathy (HIVAN), acute renal injury, HAART, and comorbid conditions such as hepatitis C, hypertension, and diabetes are among the multiple causes of renal disease. In HIVAN there is incomplete understanding of the interaction of the virus with renal cells and the host genetics leading to susceptibility to this form of renal dysfunction. There is agreement that a baseline estimated glomerular filtration should be obtained and that renal function should be monitored during antiretroviral therapy. There is, however, no agreement as to the most accurate method of estimating GFR. Renal transplantation has emerged as a feasible and successful modality of management of end-stage renal disease (ESRD) in HIV-infected individuals. SUMMARY Kidney disease represents an increasing concern in the care of HIV-infected persons, although there are questions remaining regarding the pathophysiology of HIVAN. Transplantation, however, can be carried out safely in infected persons with ESRD.

Abstract
OBJECTIVE To compare incidence and distribution of non-AIDS-defining events (NADEs) among HIV-1-infected adults receiving combination antiretroviral therapy (cART) in urban sub-Saharan African versus United States settings. DESIGN Retrospective cohort analysis of clinical trial and observational data. METHODS Compared crude and standardized (to US cohort by age and sex) NADE rates from two urban adult HIV-infected cART-initiating populations: a clinical trial cohort in Gaborone, Botswana (Botswana) and an observational cohort in Nashville, Tennessee (USA). RESULTS Crude NADE incidence rates were similar: 10.0 [95% confidence interval 6.3-15.9] per 1000 person-years in Botswana versus 12.4 [8.4-18.4] per 1000 person-years in the United States. However, after standardizing to an older, predominantly male US population, the overall NADE incidence rates were higher in Botswana [18.7 (8.3-33.1) per 1000 person-years]. Standardized rates differed most for cardiovascular events (8.4 versus 5.0 per 1000 person-years) and non-AIDS-defining malignancies (8.0 versus 0.5 per 1000 person-years) - both higher in Botswana. Conversely, hepatic NADE rates were higher in the United States (4.0 versus 0.0 per 1000 person-years), whereas renal NADE rates [3.0 per 1000 person-years (United States) versus 2.4 per 1000 person-years (Botswana)] were comparable. CONCLUSION Crude NADE incidence rates were similar between cART-treated patients in a US observational cohort and a sub-Saharan African clinical trial. However, when standardized to the US cohort, overall NADE rates were higher in Botswana. NADEs appear to be a significant problem in our sub-Saharan African setting, and the monitoring, prevention, and treatment of NADEs should be a critical component of care in resource-limited settings.

Abstract
Peripheral arterial disease (PAD) is a marker of atherosclerosis, which is not well studied in the population with human immunodeficiency virus (HIV). We prospectively enrolled HIV-infected patients who had normal resting ankle-brachial index (rABI) readings. All participants performed either a treadmill walking test (TT) or pedal plantar flexion test (PFT). Patients were divided into 2 groups according to postexercise changes; PAD and No-PAD group. The 2 groups were compared with regard to established cardiovascular disease risk factors and other HIV infection parameters. Peripheral arterial disease was present in 30 (26.5%) of 113 consecutive HIV-infected patients included in the study. Mean age was 47 ± 10 years. The risk factors studied did not differ significantly among the 2 groups except for male gender, which was significantly associated with PAD (RR: 4.15; CI: 1.6 to 11.1: P < .0008). The prevalence of PAD, diagnosed by significant drop in postexercise ABI and ankle pressure in patients with HIV is high.

Abstract
PURPOSE Serious non-AIDS (SNA) diseases are important causes of morbidity and mortality in the HAART era. We describe development of standard criteria for 12 SNA events for Endpoint Review Committee (ERC) use in START, a multicenter international HIV clinical trial. METHODS SNA definitions were developed based upon the following: (1) criteria from a previous trial (SMART), (2) review of published literature, (3) an iterative consultation and review process with the ERC and other content experts, and (4) evaluation of draft SNA criteria using retrospectively collected reports in another trial (ESPRIT). RESULTS Final criteria are presented for acute myocardial infarction, congestive heart failure, coronary artery disease requiring drug treatment, coronary revascularization, decompensated liver disease, deep vein thrombosis, diabetes mellitus, end-stage renal disease, non-AIDS cancer, peripheral arterial disease, pulmonary embolism, and stroke. Of 563 potential SNA events reported in ESPRIT and reviewed by an ERC, 72% met "confirmed" and 13% "probable" criteria. Twenty-eight percent of cases initially reviewed by the ERC required follow-up discussion (adjudication) before a final decision was reached. CONCLUSION HIV clinical trials that include SNA diseases as clinical outcomes should have standardized SNA definitions to optimize event reporting and validation and should have review by an experienced ERC with opportunities for adjudication.
