Abstract
INTRODUCTION HIV-exposed uninfected (HEU) children have higher morbidity and mortality compared with HIV unexposed uninfected children. Despite the fact that malnutrition contributes to about half of all infant deaths below 5 years of age in low-income and middle-income countries and that growth impairment has been reported in the HEU population, the spectrum of growth disorders associated with HIV and antiretroviral therapy (ART) exposure during the in utero and perinatal periods is yet to comprehensively summarised among the global HEU population. This protocol for a systematic review and meta-analysis aims to critically synthesise data concerning the prevalence of underweight, stunting and wasting at different ages in the global HEU population. METHODS AND ANALYSIS Medline, EMBASE, Cochrane Library, TOXLINE, WHO Global Index Medicus and the Web of Science will be searched for relevant articles published between 1 January 1989 and 1 December 2017 without language restriction. In addition, conference abstracts and reference lists of eligible papers and relevant review articles will be screened. Authors will screen and select studies, extract data, assess the risk of bias as well as studies individually for heterogeneity. Study-specific estimates will be pooled through a random-effects meta-analysis model for studies that are clinically homogeneous while funnel plots and Egger's test will be used to detect publication bias. Results will be presented by ART availability period, country income levels and mode of breastfeeding. ETHICS AND DISSEMINATION Ethical approval will not be required for this study because it will be based on published data. The final report of this study will be published in a peer-reviewed journal and presented at scientific conferences. This review will summarise the evidence and quantify the problem of growth impairment in HEU infants and so shed more light on our understanding of the higher morbidity and mortality in this growing population. PROSPERO REGISTRATION NUMBER CRD42018091762.

Abstract
OBJECTIVE To estimate the prevalence of liver injury among patients with acquired immunodeficiency syndrome (AIDS) who received highly active antiretroviral therapy (HAART) in rural Henan Province in China, and to explore whether Traditional Chinese Medicine (TCM) treatment based on HAART would increase this risk. METHODS This was a retrospective cross-sectional study. We collected medical information on patients with AIDS from two treatment databases in 2014. Criteria established by the AIDS Clinical Trials Group in 1996 were used for grading liver injury, classified based on the limit of normal (ULN) for alanine transaminase and aspartate aminotransferase: grade 1 (1.25-2.5 × ULN); grade 2 (2.6-5 × ULN); grade 3 (5.1-10 × ULN); and grade 4 (> 10 × ULN). Factors associated with liver injury were evaluated using a logistic regression model. RESULTS A total 6953 patients with AIDS (3324 male and 3629 female patients) were enrolled into this study. The prevalence of liver injury was 22.0% (18.0% grade 1, 3.1% grade 2, 0.9% grade 3). In multivariate analysis, patients aged 34-45 years were more likely to have liver injury than patients in other age groups [adjusted odds ratio (AOR), 1.39; 95% CI, 1.01-1.91)]. Other factors associated with liver injury included male sex (AOR, 1.64; 95% CI, 1.46-1.85), HIV infection via blood (AOR, 1.47; 95% CI, 1.19-1.82), hepatitis B virus antibody positive (AOR, 1.07; 95% CI, 0.85-1.36), and hepatitis C virus (HCV) antibody positive (AOR, 2.76; 95% CI, 2.28-3.34). CONCLUSION The prevalence of liver injury was relatively high among HAART-experienced patients. Several factors associated with liver injury included male sex, age 35-45 years old, HIV infection through blood, and concurrent HCV infection. TCM had no relationship with liver injury in patients receiving HAART.

Abstract
A 29-year-old man with diarrhoea, fever, abdominal pain and multiple purple papular lesions, neither pruriginous nor painful, was diagnosed with HIV-1 infection and disseminated Kaposi sarcoma (KS) with gastrointestinal involvement. He was started on highly active antiretroviral therapy immediately, as well as doxorubicin. Three weeks later, the patient developed bilateral moderate pleural effusion and large-volume ascites compatible with chylothorax and chylous ascites. An immune reconstitution inflammatory syndrome (IRIS) reaction was assumed. KS flare was associated with lymphatic obstruction and infiltration of thoracic duct by the tumour itself with leakage of chylous into pleural and peritoneal cavities. KS is the most common tumour in HIV patients and the existence of related effusions is not uncommon. KS-related chylothorax is an unusual manifestation of KS; there are only four cases described in the literature of chylous ascites related to KS-HIV. Overall survival is improving in KS but explosive and debilitating IRIS reactions can explain cases with poor prognosis.

Abstract
The aim of this analysis of historical data was to determine whether patients' pre-treatment beliefs about antiretroviral therapy (ART) predict the subsequent reporting of side effects. Data were collected as part of a prospective, 12-month follow-up study. Of 120 people starting ART, 76 completed follow-up assessments and were included in the analyses. Participants completed validated questionnaires assessing their beliefs about ART, beliefs about medicines in general, perceived sensitivity to adverse effects of medicines, depression and anxiety before initiating ART and after 1 and 6 months of treatment. Adherence was assessed at 1, 6 and 12 months. Pre-treatment concerns about ART were associated with significantly more side effects at 1 month (p < 0.05) and 6 months (p < 0.005). Side effects at 6 months predicted low adherence at 12 months (p < 0.005). These findings have implications for the development of interventions to support patients initiating ART by providing a mechanism to pre-empt and reduce side effects.

Abstract
BACKGROUND Direct comparisons between lamivudine plus bPIs and lamivudine plus dolutegravir as maintenance strategies in virologically-suppressed HIV positive patients are lacking. METHODS Time to treatment discontinuation (TD) and virological failure (VF) were compared in a cohort of HIV+ patients on a virologically-effective ART starting lamivudine with either darunavir/r, atazanavir/r or dolutegravir. Changes in laboratory parameters were also evaluated. RESULTS Four-hundred-ninety-four patients were analyzed (170 switching to darunavir/r, 141 to atazanavir/r, 183 to dolutegravir): median age was 49 years, with 8 years since ART start. Groups differed for age, HIV-risk factor, time since HIV-diagnosis and on ART, previous therapy and reasons for switching. Estimated proportions free from TD at week 48 and 96 were 79.8 and 48.3% of patients with darunavir/r, 87.0 and 70.9% with atazanavir/r, and 88.2 and 82.6% with dolutegravir, respectively (p < 0.001). Calendar years, HIV-risk factor, higher baseline cholesterol and an InSTI-based previous regimen predicted TD, whereas lamivudine+dolutegravir therapy and previous tenofovir use were protective. VF was the cause of TD in 6/123 cases with darunavir/r, 4/97 with atazanavir/r and 3/21 with dolutegravir. Other main reasons for TD were: toxicity (43.1% with darunavir/r, 39.2% with atazanavir/r, 52.4% with dolutegravir), further simplification (36.6% with darunavir/r, 30.9% with atazanavir/r, 14.3% with dolutegravir). Incidence of VF did not differ among study groups (p = 0.747). No factor could predict VF. Lipid profile improved in the dolutegravir group, whereas renal function improved in the bPIs groups. CONCLUSIONS In real practice, a switch to lamivudine+dolutegravir showed similar efficacy but longer durability than a switch to lamivudine+bPIs.

Abstract
BACKGROUND Antiretroviral-related adverse drug reactions (ADRs) are one of the leading causes of drug changes, poor adherence, and treatment failure. Therefore, this study was designed to assess the magnitude of ADR and associated factors among pediatric patients on antiretroviral therapy (ART). METHODS A retrospective cross-sectional study was conducted by reviewing the medical records of pediatric patients on ART at Hiwot Fana Specialized University Hospital and Jugal Hospital ART clinics. The collected data were coded, entered, and analyzed using SPSS, IBM version 16. The associations of selected categorical variables were done using binary logistic and multivariate logistic regression. RESULTS Of 186 medical records of pediatric patients on ART, 153 (82.25%) were reviewed. From the total medical records assessed, ADRs were observed in 23 (15.03%) of pediatric patients on ART, of which the most commonly encountered ADRs were anemia (34.8%) and followed by rash (17.4%). Most of ADRs were ranked as grade 3 (39.13%) and followed by grade 2 (30.4%) based on the degree of their severity. The likelihood of developing ADR was significantly associated with the regimen AZT/3TC/NVP (adjusted odds ratio: 6.420; 95% confidence interval: 1.056-39.018) relative to pediatric patients on D4T/3TC/NVP regimen. CONCLUSION This study indicated that few pediatric patients on ART experienced ADRs. Most of the observed ADRs were ranked as grade 2 and 3 in terms of their severity. Drug out of stock and ADRs were the 2 most common reasons for antiretroviral (ARV) drug regimen change that could affect patient's treatment outcome and limited future option.

Abstract
The concept of successful aging was recognized only recently by HIV researchers because people living with HIV (PLWH) in the early epidemic were not expected to survive. With the introduction of antiretrovirals that block viral replication, PLWH are now aging with HIV. Given the complex nature of HIV within the social, economic, and political climates in which it occurs, a holistic model of successful aging is needed to guide researchers and clinicians. Several overarching models exist, but must be updated for rapidly advancing HIV and aging research agendas. We provide an updated, adapted, and integrated biopsychosocial model of successful aging with HIV based on the principles of Baltes and Baltes (1998) on 8 essential components of successful aging: (a) length of life, (b) biological health, (c) mental health, (d) cognitive efficiency, (e) social competence, (f) productivity, (g) personal control, and (h) life satisfaction. Clinical practice and research implications are highlighted.

Abstract
PURPOSE A high risk of cardiovascular disease (CVD) is reported for HIV-infected individuals. While a link between abacavir and CVD risk is suggested, an association between abacavir and hypertension remains unclear. This study evaluated hypertension risk with abacavir use in comparison to non-abacavir antiretroviral treatment (ART). MATERIALS AND METHODS From a nationwide cohort of HIV-infected individuals on their initial ART, 6493 who were free of hypertension at baseline were analyzed. The use of ART was treated as a time-varying covariate measured as a daily unit. Incidence rate of hypertension was calculated, and Cox proportional hazard models were used to estimate adjusted hazard ratios (HRs) with 95% confidence interval (CI) of incident hypertension overall and among subgroups. RESULTS From the 6493 participants, 24072 person-years (PY) of follow-up were contributed during 2008-2016. The incidence rates of hypertension were 4.6 and 3.6 per 100 PY for abacavir and non-abacavir ART users, respectively. The population attributable fraction of abacavir use on hypertension was 12%. Abacavir exposure did not elevate the risk of hypertension among overall study population [HR, 1.2 (95% CI, 1.0-1.4), p=0.061]. However, those with poor ART adherence, defined as a medication possession ratio <50% [HR, 1.9 (95% CI, 1.5-2.4), p<0.0001] or requiring prophylactic antibiotics [HR, 1.2 (95% CI, 1.0-1.3), p=0.023], were at risk of hypertension induced by abacavir, as were men, individuals aged ≥40 years, and patients visiting tertiary hospitals in urban areas. CONCLUSION When present, poor ART adherence, requiring prophylactic antibiotics, male sex, and older age may warrant additional concern for hypertension in patients treated with abacavir.

Abstract
BACKGROUND In utero exposure to nucleoside reverse transcriptase inhibitor (NRTI)-containing antiretroviral treatment (ART) regimens may be associated with poor neurodevelopmental functioning in children of HIV-infected mothers. We investigated neurodevelopmental outcomes of HIV-exposed uninfected (HEU) children of HIV-infected women enrolled in a randomized trial of abacavir/zidovudine/lamivudine (triple-NRTI regimen) vs. lopinavir/ritonavir/zidovudine/lamivudine [dual-NRTI + protease inhibitor (PI) regimen]. SETTING The Mma Bana randomized trial was conducted in urban and rural sites in Botswana. METHODS The Mma Bana study randomized HIV-infected pregnant women with CD4 ≥200 cells per mm to a triple-NRTI vs. dual-NRTI + PI regimen from 26- to 34-week gestation through planned weaning at 6-month postpartum. Partway through the study, neurodevelopmental assessments were added at 24 months of age, including the Developmental Milestones Checklist, the Bayley Scales of Infant and Toddler Development third edition, Ten Questions Questionnaire, and Profile of Social Emotional Development. We evaluated differences in mean scores between the 2 arms using unadjusted and adjusted linear regression. RESULTS A total of 197 HEU infants (48% male) completed a neurodevelopmental assessment (101 in triple-NRTI arm and 96 in dual-NRTI + PI-exposed arm). Mean values for all neurodevelopmental outcomes were similar for children of mothers randomized to either ART regimen, with no significant differences in either unadjusted or adjusted models (estimated effect sizes ranging from -0.12 to 0.14). CONCLUSIONS Neurodevelopmental outcomes in 24-month-old HEU children of HIV-infected mothers with baseline CD4 ≥200 were similar in those randomized to a dual-NRTI + PI-based vs. a triple-NRTI-based ART regimen, suggestive of lack of short-term toxicity. Monitoring of long-term toxicity and newer regimens is warranted.

Abstract
Cardiovascular diseases and thrombotic events became major clinical problems in the combined antiretroviral therapy (cART) era. Although the precise mechanisms behind these clinical problems have not been fully elucidated, a persistent pro-inflammatory state plays a central role. As platelets play important roles on both, thrombus formation and inflammatory/immune response, we aimed at investigating platelet function in HIV-infected subjects virologically controlled through cART. We evaluate parameters of activation, mitochondrial function and activation of apoptosis pathways in platelets from 30 HIV-infected individuals under stable cART and 36 healthy volunteers. Despite viral control achieved through cART, HIV-infected individuals exhibited increased platelet activation as indicated by P-selectin expression and platelet spreading when adhered on fibrinogen-coated surfaces. Platelets from HIV-infected subjects also exhibited mitochondrial dysfunction and activation of apoptosis pathways. Finally, thrombin stimuli induced lower levels of P-selectin translocation and RANTES secretion, but not TXA2 synthesis, in platelets from HIV-infected individuals compared to control; and labeling of platelet alpha granules showed reduced granule content in platelets from HIV-infected individuals when compared to healthy subjects. In summary, platelets derived from HIV-infected individuals under stable cART exhibit a phenotype of increased activation, activation of the intrinsic pathway of apoptosis and undermined granule secretion in response to thrombin.

Abstract
BACKGROUND Combination antiretroviral therapy has allowed youth with perinatal HIV infection (PHIV+) to live into adulthood, but many youth may experience metabolic and body composition changes that predispose to greater cardiovascular disease (CVD) risk. This longitudinal study evaluated changes in body composition measured by dual-energy radiograph absorptiometry (DXA) in a cohort of PHIV+ youth compared with HIV- controls over a 7-year period. METHODS PHIV+ youth and HIV- controls were prospectively enrolled in a single-site study to assess nutrition and CVD risk. Anthropometrics and DXA scans were longitudinally obtained to assess percent body fat and regional fat distribution. Using general linear models, we analyzed differences in body composition and anthropometric measures by sex between PHIV+ youth and controls over time. RESULTS Two hundred thirty-five participants (156 PHIV+ and 79 HIV- controls) with at least 1 DXA performed since study enrollment were included for analysis. During the study period, 471 DXAs were obtained in the PHIV+ group and 95 in HIV- controls. PHIV+ females demonstrated greater increase in weight and body mass index over time compared with HIV- females, and significant increases in total percent body fat [estimate = 1.212 (95% confidence interval: 0.837-1.587) percent per year; P < 0.001) and percent trunk fat [1.3818 (95% confidence interval: 0.922-1.84); P < 0.001] compared with HIV- females and PHIV+ males. CONCLUSIONS PHIV+ females demonstrate an unfavorable change in fat redistribution and percent body fat over time that exceeds the pattern seen in PHIV+ males or HIV- females. Providers should have heightened awareness of body composition changes of PHIV+ females that may eventually lead to increased CVD risk.

Abstract
Worldwide, nearly two million children are infected with human immunodeficiency virus (HIV), with breastfeeding accounting for the majority of contemporary HIV transmissions. Antiretroviral therapy (ART) has reduced HIV-related morbidity and mortality but is not curative. The main barrier to a cure is persistence of latent HIV in long-lived reservoirs. However, our understanding of the cellular and anatomic sources of the HIV reservoir during infancy and childhood is limited. Here, we developed a pediatric model of ART suppression in orally simian immunodeficiency virus (SIV)-infected rhesus macaque (RM) infants, with measurement of virus persistence in blood and tissues after 6 to 9 months of ART. Cross-sectional analyses were conducted to compare SIV RNA and DNA levels in adult and infant RMs naive to treatment and on ART. We demonstrate efficient viral suppression following ART initiation in SIV-infected RM infants with sustained undetectable plasma viral loads in the setting of heterogeneous penetration of ART into lymphoid and gastrointestinal tissues and low drug levels in the brain. We further show reduction in SIV RNA and DNA on ART in lymphoid tissues of both infant and adult RMs but stable (albeit low) levels of SIV RNA and DNA in the brains of viremic and ART-suppressed infants. Finally, we report a large contribution of naive CD4+ T cells to the total CD4 reservoir of SIV in blood and lymph nodes of ART-suppressed RM infants that differs from what we show in adults. These results reveal important aspects of HIV/SIV persistence in infants and provide insight into strategic targets for cure interventions in a pediatric population.IMPORTANCE While antiretroviral therapy (ART) can reduce HIV replication, the virus cannot be eradicated from an infected individual, and our incomplete understanding of HIV persistence in reservoirs greatly complicates the generation of a cure for HIV infection. Given the immaturity of the infant immune system, it is critically important to study HIV reservoirs specifically in this population. Here, we established a pediatric animal model to simulate breastfeeding transmission and study SIV reservoirs in rhesus macaque (RM) infants. Our study demonstrates that ART can be safely administered to infant RMs for prolonged periods and that it efficiently controls viral replication in this model. SIV persistence was shown in blood and tissues, with similar anatomic distributions of SIV reservoirs in infant and adult RMs. However, in the peripheral blood and lymph nodes, a greater contribution of the naive CD4+ T cells to the SIV reservoir was observed in infants than in adults.

Abstract
OBJECTIVE Antiretroviral therapy (ART) is currently recommended for all persons living with HIV (PLWH), regardless of their CD4 T-cell count, and should be continued throughout life. Nonetheless, vigilance of the safety of ART, including its neurotoxicity, must continue. We hypothesized that use of certain ART drugs might be associated with aging-related cerebral degenerative changes among PLWH. DESIGN Clinicopathological study of PLWH who were using ART drugs at the last clinical assessment. METHODS Using multivariable logistic regression, we tested associations between use of each specific ART drug (with reference to use of other ART drugs) and cerebral degenerative changes including neuronal phospho-tau lesions, β-amyloid plaque deposition, microgliosis, and astrogliosis in the frontal cortex and putamen (immunohistochemistry), as well as cerebral small vessel disease (CSVD) in the forebrain white matter (standard histopathology), with relevant covariates being taken into account. The Bonferroni adjustment was applied. RESULTS Darunavir use was associated with higher likelihood of neuronal phospho-tau lesions in the putamen [odds ratio (OR) 15.33, n = 93, P = 0.005]. Ritonavir use was associated with marked microgliosis in the putamen (OR 4.96, n = 101, P = 0.023). On the other hand, use of tenofovir disoproxil fumarate was associated with lower likelihood of β-amyloid plaque deposition in the frontal cortex (OR 0.13, n = 102, P = 0.012). There was a trend toward an association between emtricitabine use and CSVD (OR 13.64, n = 75, P = 0.099). CONCLUSION Our findings suggest that PLWH treated with darunavir and ritonavir may be at increased risk of aging-related cerebral degenerative changes.

Abstract
Previous studies have shown that the incidence of diabetes mellitus (DM) has increased in human immunodeficiency virus (HIV)-infected patients with long-term exposure to highly active antiretroviral therapy (HAART). However, the factors associated with DM among HIV-infected patients in Asia remain unclear in the HAART era.A nationwide cohort studyData from Taiwan's National Health Insurance Research Database (NHIRD) between 2000 and 2010 were used to investigate the incidence of and factors associated with DM among HIV-infected patients. Propensity score matching was conducted to match 4797 patients receiving HAART (HAART cohort) with 4797 patients not receiving HAART (non-HAART cohort). HAART use was treated as a time-dependent variable in a Cox regression model.HAART cohort had a significantly higher 10-year incidence of DM (7.16%; 95% confidence interval [CI], 4.30%-10.03%) than non-HAART cohort (2.24%; 95% CI, 1.28%-3.20%) (P < .001). After adjusting for age, gender, and comorbidities, receiving HAART was associated with an increased incidence of DM, with a subdistribution hazard ratio (sHR) of 2.39 (95% CI, 1.65-3.45). Hypertension (sHR = 5.27; 95% CI, 3.21-8.65), gout (sHR = 2.39; 95% CI, 1.38-4.16), and hepatitis C virus (HCV) infection (sHR = 2.43; 95% CI, 1.28-4.61) were significantly associated with a higher risk of DM. Sensitivity analyses showed exposure to HAART remained significantly associated with an increased risk of DM, particularly in those without pre-existing hypertension, gout, or HCV infection.Exposure to HAART increased the risk of DM in HIV-infected Taiwanese patients, particularly in those without pre-existing hypertension, gout, or HCV infection.

Abstract
HIV-1-affected couples' desire to have children and free sexual intercourses with the use of pre-exposure prophylaxis for the negative partner has emerged as an alternative option to assisted reproduction in aviremic patients under highly active antiretroviral therapy (HAART). It is already known that sperm quality may be impaired in HIV-infected men. The underlying physiopathological mechanism is still debated. The aim of this study was to evaluate the effects of HAART on sperm DNA fragmentation, comparing HIV-1-infected patients taking HAART versus naïve HIV-1-infected patients. This is a prospective case-control study. Sperm nuclear DNA fragmentation rate was evaluated by the sperm chromatin dispersion test in 77 HIV-infected men: 53 HIV-1 patients receiving HAART (Group 1) versus 24 naïve HIV-1 patients not receiving HAART (Group 2). Complete semen analysis was performed according to WHO 2010 recommendations. Patients with HBV infection or HCV infection coinfections and genital tract infections wre excluded. All the patients did not present any clinical signs of their disease. Seminal parameters were examined in the two groups, showing no significant differences. Increased sperm DNA fragmentation > 30% was demonstrated in 67.9% of patients in Group 1 and 37.5% of patients in Group 2, respectively ( p = .02). A positive but nonsignificant trend toward increased fragmentation was reported with advancing patients' age. In conclusion, sperm nuclear fragmentation rate is increased in HIV-1-infected patients taking HAART compared to HIV-1 patients not receiving HAART.

Abstract
BACKGROUND Hepatitis B (HBV)-HIV coinfection is associated with liver inflammation, which can progress to liver fibrosis/cirrhosis and hepatocellular carcinoma. We determined HBV seroprevalence in children and adolescents participating in the TREAT Asia Pediatric HIV Observational Database. METHODS A multisite cross-sectional study was conducted in HIV-infected patients currently <25 years old receiving antiretroviral treatment (ART) who had HBV surface antigen (HBsAg), or HBV surface antibody (anti-HBs) or HBV core antibody (anti-HBc) tested during 2012-2013. HBV coinfection was defined as having either a positive HBsAg test or being anti-HBc positive and anti-HBs negative, reflective of past HBV infection. HBV seroprotection was defined as having a positive anti-HBs test. RESULTS A total of 3380 patients from 6 countries (Vietnam, Thailand, Cambodia, Malaysia, Indonesia and India) were included. The current median (interquartile range) age was 11.2 (7.8-15.1) years. Of the 2755 patients (81.5%) with HBsAg testing, 130 (4.7%) were positive. Of 1558 (46%) with anti-HBc testing, 77 (4.9%) were positive. Thirteen of 1037 patients with all 3 tests were anti-HBc positive and HBsAg and anti-HBs negative. One child was positive for anti-HBc and negative for anti-HBs but did not have HBsAg tested. The prevalence of HBV coinfection was 144/2759 (5.2%) (95% confidence interval: 4.4-6.1). Of 1093 patients (32%) with anti-HBs testing, 257 (23.5%; confidence interval: 21.0-26.0) had positive tests representing HBV seroprotection. CONCLUSIONS The estimated prevalence of HBV coinfection in this cohort of Asian HIV-infected children and adolescents on ART was 5.2%. The majority of children and adolescents tested in this cohort (76.5%) did not have protective HBV antibody. The finding supports HBV screening of HIV-infected children and adolescents to guide revaccination, the use of ART with anti-HBV activity and future monitoring.

Abstract
BACKGROUND Incident heart failure (HF) is increased in persons with human immunodeficiency virus (PHIV). Protease inhibitors (PIs) are associated with adverse cardiac remodeling and vascular events; however, there are no data on the use of PIs in PHIV with HF. OBJECTIVES This study sought to compare characteristics, cardiac structure, and outcomes in PHIV with HF who were receiving PI-based versus non-PI (NPI) therapy. METHODS This was a retrospective single-center study of all 394 antiretroviral therapy-treated PHIV who were hospitalized with HF in 2011, stratified by PI and NPI. The primary outcome was cardiovascular (CV) mortality, and the secondary outcome was 30-day HF readmission rate. RESULTS Of the 394 PHIV with HF (47% female, mean age 60 ± 9.5 years, CD4 count 292 ± 206 cells/mm3), 145 (37%) were prescribed a PI, whereas 249 (63%) were prescribed NPI regimens. All PI-based antiretroviral therapy contained boosted-dose ritonavir. PHIV who were receiving a PI had higher rates of hyperlipidemia, diabetes mellitus, and coronary artery disease (CAD); higher pulmonary artery systolic pressure (PASP); and lower left ventricular ejection fraction. In follow-up, PI use was associated with increased CV mortality (35% vs. 17%; p < 0.001) and 30-day HF readmission (68% vs. 34%; p < 0.001), effects seen in all HF types. Predictors of CV mortality included PI use, CAD, PASP, and immunosuppression. Overall, PIs were associated with a 2-fold increased risk of CV mortality. CONCLUSIONS PI-based regimens in PHIV with HF are associated with dyslipidemia, diabetes, CAD, a lower left ventricular ejection fraction, and a higher PASP. In follow-up, PHIV with HF who are receiving a PI have increased CV mortality and 30-day HF readmission.

Abstract
With the introduction of Highly Active Antiretroviral Therapy (HAART), there has been drastic decline in morbidity and mortality associated with HIV/AIDS. However, many patients experience adverse drug reactions perhaps due to the inherent toxic nature of HAART. The possible toxic effect of HAART (combination ARVs) on reproduction and sexual dysfunction in seropositive HIV patients remains a subject of intense research. This study was designed to investigate the toxic effects of HAART on the reproductive hormones and organs of male and female rats. Sexually mature adult male and female rats were administered therapeutic doses of single and combination antiretroviral drugs for 48 days and thereafter sacrificed under anaesthesia. Morphological and histopathological examination of the testes and ovaries were carried out. Serum biochemical assay, semen quality analysis and hormonal assays were also conducted using standard methods. Results show significant (p < 0.05) reductions in the weight of testes and epididymis across all groups versus control; sperm count and motility were also significantly reduced in the test groups while hormonal analysis in males revealed significant reductions in LH, FSH and Testosterone. In the females, there was a significant (p < 0.05) reduction in the number of ovarian follicles, prolactin, estrogen and progesterone. We thus conclude that the administration of single and combined antiretroviral drugs have potential reproductive toxic effects.

Abstract
The abrupt development of multiple melanocytic nevi has been described in association with many conditions, including human immunodeficiency virus infection. We report three cases of eruptive nevi in men with human immunodeficiency virus type 1 infection. One patient developed this phenomenon during the stage of acquired immunodeficiency syndrome. The other two patients had human immunodeficiency virus infection recently diagnosed and presented to our clinic reporting the development of multiple melanocytic nevi after starting highly active antiretroviral treatment, with improvement of their immunity. To our knowledge, this is the first report of eruptive melanocytic nevi as a possible consequence of the immune reconstitution inflammatory syndrome.

Abstract
Background Cancer causes significant morbidity and mortality among HIV patients in the US due to extended life expectancy with access to effective antiretroviral therapy. Low, detectable HIV RNA has been studied as a risk factor for adverse health outcomes, but its clinical impact on cancer risk remains unclear. The objective of this study was to determine whether HIV RNA <1,000 copies/mL six months after starting therapy was associated with 10-year first cancer risk. Methods We followed 7,515 HIV therapy initiators from a US-based multicenter clinical cohort from 1998 to 2014. We used nonparametric multiple imputation to account for viral loads that fell below assay detection limits, and categorized viral loads six months after therapy initiation into four groups: <20, 20–199, 200–999, and >999 copies/mL. We calculated estimates of the cumulative incidence of cancer diagnosis, accounting for death as a competing event. Inverse probability of exposure and censoring weights were used to control for confounding and differential loss to follow up, respectively. Results Crude 10-year first cancer risk in the study sample was 7.03% (95% CI: 6.08%, 7.98%), with the highest risk observed among patients with viral loads between 200 and 999 copies/mL six months after ART initiation (10.7%). After controlling for baseline confounders, 10-year first cancer risk was 6.90% (95% CI: 5.69%, 8.12%), and was similar across viral load categories. Conclusion Overall risk of first cancer was not associated with incomplete viral suppression; however, cancer remains a significant threat to HIV patients after treatment initiation. As more HIV patients gain access to treatment in the current “treat all” era, occurrences of incomplete viral suppression will be observed more frequently in clinical practice, which supports continued study of the role of low-level HIV RNA on cancer development.

Abstract
Metabolic syndrome (MetS), a cluster of cardiovascular disease risk factors, is increasingly common in people living with HIV; however, data on prevalence and the role of antiretroviral therapy (ART) as a risk factor for MetS in sub-Saharan Africa are lacking. We conducted a cross-sectional study to assess the prevalence and risk factors for MetS among ART-naive and ART-experienced HIV-infected adults without preexisting cardiometabolic disorders in Western Kenya using validated questionnaires and laboratory tests after overnight fasting. We used logistic regression to identify associations between traditional risk factors, HIV disease characteristics, ART, and MetS. Study participants included 164 ART-experienced patients, majority (56%) on tenofovir/lamivudine/nevirapine regimen, and 136 ART-naive patients. The median age was 40 (interquartile range, 33-46) years and 64% were women. Median HIV infection and ART use were 4.6 (1.7-7.9) and 4.8 (2.7-7.8) years, respectively. Prevalence of MetS did not differ between ART-experienced (16.9%) and -naive (15.2%) groups. ART-experienced patients had higher rates of elevated fasting blood sugars and lower rates of low high-density lipoprotein-cholesterol. The prevalence of abnormal waist circumference, elevated blood pressure, and hypertriglyceridemia were comparable between the two groups. Older age, female sex, and high body mass index were independently associated with diagnosis of MetS. Traditional risk factors rather than ART-related effects were more important predictors of MetS in this cohort and may have been influenced by ART type and exclusion of preexisting hypertension and diabetes. HIV-infected patients without preexisting cardiometabolic disorders should be monitored for metabolic abnormalities regardless of ART.

Abstract
Many patients previously using darunavir/ritonavir (DRV/r) (800/100mg) have switched to darunavir/cobicistat (DRV/C) (800/150 mg) either as part of triple therapy (ART) or as monotherapy with DRV (mDRV). The latter approach continues to be used in some countries for patients receiving long-term treatment. However, to date, the behaviour of DRV/C in the seminal compartment has not been analysed. This study explores how the combination behaves in monotherapy, with respect to the control of viral load and seminal quality. To this end, we studied 20 patients who were treated with mDRV/C after previous treatment with mDRV/r for at least 24 weeks. A viral load control in seminal plasma similar to that published in the literature was observed after 24 weeks of treatment with mDRV/C (viral load positivity in 20% of patients). Similarly, semen quality was confirmed (70% normozoospermic) in patients treated with this formulation, as has previously been reported for ART and mDRV/r. The DRV levels measured in seminal plasma were above EC50, regardless of whether the seminal viral load was positive or negative. We conclude that this mDRV/C co-formulation behaves like mDRV/r in seminal plasma in terms of viral load control and semen quality.

Abstract
We previously demonstrated superior efficacy and safety advantages in HIV-infected, virologically suppressed adults switched to a regimen containing tenofovir alafenamide (TAF) as compared with those remaining on a tenofovir disoproxil fumarate (TDF) regimen through week 48. We now report long-term data through week 96. In this randomized, active-controlled, multicenter, open-label, noninferiority trial (ClinicalTrials.gov No. NCT01815736), we randomized virologically suppressed (HIV-1 RNA <50 copies/ml) adults (2:1) to receive a once-daily, single-tablet regimen containing elvitegravir (EVG), cobicistat (COBI), emtricitabine (FTC), and TAF group or to continue one of four TDF-containing regimens (TDF group) for 96 weeks. We evaluated efficacy (HIV-1 RNA <50 copies/ml using the FDA snapshot algorithm) and prespecified bone and renal endpoints at week 96. We randomized and treated 1,436 participants in this study (TAF n = 959, TDF n = 477). At week 96, TAF was superior to TDF in virologic efficacy, with 93% on TAF and 89% on TDF having HIV-1 RNA <50 copies/ml (difference 3.7%, 95% confidence interval: 0.4%-7.0%). Improvements in hip and spine bone mineral density for those assigned to TAF versus TDF continued through week 96 (p < .001). Significant improvements in urine protein or albumin to creatinine ratios were also seen among those in the TAF group versus TDF through week 96 (p < .001). There were no cases of investigator-reported proximal renal tubulopathy in the TAF group as compared with one case in the TDF group. Switching to EVG/COBI/FTC/TAF (E/C/F/TAF) was associated with statistically significant efficacy and safety advantages over remaining on a standard-of-care TDF-based regimen.
