Recently identified T memory stem (Tscm) cells have stem-cell-like properties, including long lifespan, self-renewal capacity, and multipotency to differentiate into other memory T cell types. In the study of simian immunodeficiency virus (SIV) infection, selective depletion of CCR5(+)CD4(+) Tscm cells and the high proliferation rate of these cells are believed to be responsible for the pathogenesis of SIV-infected rhesus macaques. Here, we conducted a cohort study to investigate the influence of chronic human immunodeficiency virus (HIV)-1 infection on CD4(+) Tscm cell homeostasis, and the effect of antiretroviral therapy (ART) on CD4(+) Tscm cells...

BACKGROUND: Hepatocellular carcinoma (HCC) is a leading cause of liver-related mortality in people living with HIV, where co-infection with hepatotropic viruses accelerates the course of chronic liver disease. AIM: To evaluate whether the albumin-bilirubin (ALBI) grade, a more accurate marker of liver dysfunction in HCC, might identify patients with progressive liver dysfunction in the context of HIV/hepatitis co-infection. METHODS: Using uni- and multi-variable analyses, we studied the albumin-bilirubin grade as a predictor of overall survival (OS) in a large, multi-center cohort of patients with HIV-associated HCC recruited from 44 centres in 9 countries within the Liver Cancer in HIV study group...

Background: Due to changes in guidelines and access to treatment, more children start combination antiretroviral therapy (ART) in infancy. With few studies examining the long-term effects of perinatal HIV infection and early ART on neurodevelopment, much is still unknown about brain maturation in the presence of HIV and ART. Follow-up studies of HIV infected (HIV+) children are important for monitoring brain development in the presence of HIV infection and ART. Methods: We use diffusion tensor imaging (DTI) to examine white matter (WM) in 65 HIV+ and 46 control (HIV exposed uninfected (HEU) and HIV unexposed uninfected (HU)) 7-year-old children...

OBJECTIVE: Fibroblast growth factor 21 (FGF21) ameliorates steatohepatitis but is increased in humans with fatty liver, potentially due to compensatory mechanisms and/or FGF21 resistance. Further, animal models suggest that GH increases serum FGF21. Tesamorelin, a growth hormone releasing hormone agonist, reduces liver fat in HIV-infected individuals. The objectives of this study were to investigate changes in FGF21 during tesamorelin treatment, to elucide the interplay between FGF21, GH augmentation, and liver fat reduction in humans...

The northern pig-tailed macaque (Macaca leonina) has been considered as an independent species from the pig-tailed macaque group. We have previously reported that this species macaque has the potential to be a useful animal model in HIV/AIDS pathogenesis and vaccine studies due to its susceptibility to HIV-1. To develop this animal into a potential HIV/AIDS model, we have studied the classical MHC genes of this animal. In this study, the non-classical MHC genes Malo-DM and Malo-DO alleles were first characterized by sequencing and cloning in 12 unrelated northern pig-tailed macaques...

BACKGROUND: Requirements for frequent dispensing of antiretroviral therapy (ART) place demands on health systems and can lead to suboptimal adherence and disengagement in care for patients due to the time and cost of frequent clinic visits. Rigorous data are needed to define optimal ART dispensing strategies and to evaluate the impact of a longer medication supply on retention and virologic suppression and determine whether this strategy lowers costs for both the patient and the health system...

Pathogen strains may differ in virulence because they attain different loads in their hosts, or because they induce different disease-causing mechanisms independent of their load. In evolutionary ecology, the latter is referred to as" per-parasite pathogenicity". Using viral load and CD4+ T cell measures from 2014 HIV-1 subtype B infected individuals enrolled in the Swiss HIV Cohort Study, we investigated if virulence - measured as the rate of decline of CD4+ T cells - and per-parasite pathogenicity are heritable from donor to recipient...

Background: Cardiovascular disease (CVD) is expected to contribute a large non-communicable disease burden amongst HIV-positive people. We quantify the impact of prevention interventions on annual CVD burden and costs amongst HIV-positive people in The Netherlands. Methods: We constructed an individual-based model of CVD in HIV-positive people using national ATHENA cohort data on 8,791 patients on combination antiretroviral therapy (cART). The model follows patients as they age, develop CVD (by incorporating a CVD risk equation) and start cardiovascular medication...

Background: Prior to the wide availability of antiretroviral therapy, tuberculosis (TB) and HIV disease among pregnant women resulted in poor maternal and neonatal outcomes including high rates of mother-to-child transmission of both HIV and TB. We aimed to describe the impact of TB among HIV-infected mothers on obstetric and infant outcomes in a population with access to antiretroviral therapy. Methods: In this prospective cohort study, we followed HIV-infected pregnant women with and without TB disease from January 2011 through January 2014 in Soweto, South Africa...

Introduction: Knowledge of the characteristics and risk factors of individuals with an asymptomatic sexually transmitted infection (STI) is essential for implementation of targeted STI screening strategies. Methods: Between June 2015 and January 2017 an STI screening was offered to all participants in the Zurich Primary HIV-1 Infection Study. Patients were tested for gonorrhea, chlamydia, syphilis, and hepatitis C virus. Determinants of STI prevalence and incidence were assessed using mixed-model logistic regression and survival analysis...

Cryptococcal meningitis (CM) is the primary cause of meningitis in HIV-infected adults and an emerging disease in HIV-seronegative individuals. No literature review has studied the long-term outcome of CM. We performed a systematic review on the long-term (≥3 months) impact of CM (C. neoformans and C. gattii) on mortality and disability in HIV-infected and non-HIV-infected adults. Though the quality of current evidence is limited, the long-term impact of CM on survival and disability appears to be high. One-year mortality ranged from 13% in an Australian non-HIV C...

BACKGROUND: Symptoms of acute retroviral syndrome (ARS) may be used to identify patients with acute HIV-1 infection who seek care. ARS symptoms in African adults differ by region. We assessed whether reporting of ARS was associated with HIV-1 subtype in a multicentre African cohort study representing countries with predominant HIV-1 subtypes A, C and D. METHODOLOGY: ARS symptoms were assessed in adults enrolling ≤6 weeks after the estimated date of infection (EDI) in an acute and early HIV-1 infection cohort study...

We aimed to determine the initial adherence of HIV cohort patients to ART (antiretroviral therapy), and reasons for non-adherence. Patients who received ART at the time of enrollment in the Korea HIV/AIDS Cohort were included in this study. Treatment adherence was determined at the baseline interview by self-reported questionnaire. Eight-hundred thirty two HIV-infected patients received ART. Of these, 253 (30.4%) patients skipped ART more than once a month. The most common reason of skipping medication was "simply forgot" (60...

BACKGROUND: HIV-infected individuals have an increased risk of avascular bone necrosis (AVN). Antiretroviral therapy (ART) and particularly protease inhibitors (PI) have been implicated as a risk factor. We aimed to study the associations of ART with the occurrence of AVN among Swiss HIV Cohort Study participants (SHCS). METHODS: We used incidence density sampling to perform a case control study within the Swiss HIV Cohort Study (SHCS) comparing prospectively collected AVN cases and controls by conditional logistic regression analysis...

BACKGROUND: Exclusive breastfeeding (EBF) for the first six months of life is the most important determinant of child health and development, and is the recommended feeding practice for all mothers. However, EBF rates remain low in South Africa. This study aimed to prospectively explore enablers or barriers to success among mothers who planned to exclusively breastfeed their infants for the first six months of life, in KwaZulu-Natal, South Africa. METHODS: A qualitative, longitudinal cohort design was adopted...
