Most HIV research in Sub-Saharan Africa (SSA) ignores persons aged 50 years and above, though a few studies have reported a high HIV prevalence among older people. This study aimed to estimate socio-demographic inequalities in HIV testing behaviour and HIV prevalence among adults aged 50+ years, living in Ifakara town, Tanzania. This cross-sectional study used data from the baseline measurement of the Ifakara MZIMA cohort study in 2012/13. Consenting participants were interviewed and tested for HIV. Associations between HIV testing behaviour and HIV prevalence with socio-demographic indicators were explored with multivariable logistic regression...

Liver fibrosis is common, particularly in human immunodeficiency virus infected (HIV+) people. HIV+ people have excess congestive heart failure (CHF) risk compared to uninfected people. It remains unknown if stage of liver fibrosis influences the CHF risk or if HIV or hepatitis C virus (HCV) infection modifies this association. Our objectives were to assess whether: 1) stage of liver fibrosis is independently associated with incident CHF; 2) the association between stage of liver fibrosis and incident CHF is modified by HIV/HCV status...

Most studies evaluating epidemiologic relationships between helminths and HIV have been conducted in the pre-ART era, and evidence of the impact of helminth infections on HIV disease progression remains conflicting. Less is known about helminth infection and clinical outcomes in HIV-infected adults receiving antiretroviral therapy (ART). We sampled HIV-infected adults for eight gastrointestinal parasites and correlated parasitic infection with demographic predictors, and clinical and immunologic outcomes. Contrasting with previous studies, we measured parasitic infection with a quantitative, highly sensitive and specific polymerase chain reaction (PCR) method...

To characterize HIV-1 transmission dynamics in regions where the burden of HIV-1 is greatest, the 'Phylogenetics and Networks for Generalised HIV Epidemics in Africa' consortium (PANGEA-HIV) is sequencing full-genome viral isolates from across sub-Saharan Africa. We report the first 3,985 PANGEA-HIV consensus sequences from four cohort sites (Rakai Community Cohort Study, n=2,833; MRC/UVRI Uganda, n=701; Mochudi Prevention Project, n=359; Africa Health Research Institute Resistance Cohort, n=92). Next-generation sequencing success rates varied: more than 80% of the viral genome from the gag to the nef genes could be determined for all sequences from South Africa, 75% of sequences from Mochudi, 60% of sequences from MRC/UVRI Uganda, and 22% of sequences from Rakai...

OBJECTIVE: There is inconsistent evidence that zidovudine use during pregnancy increases overall, cardiac, and male genital malformations. DESIGN: We conducted a systematic review and meta-analysis of zidovudine use and malformations and, using Bayesian methods, combined it with data from a cohort study of mother-infant pairs in the nationwide Medicaid Analytic eXtract (MAX). METHODS: Using MAX data (2000-2010), we identified pregnant women with HIV treated with antiretroviral therapy (ART)...

: There is a long-lasting controversy surrounding an association between Abacavir (ABC) and an increased risk of cardiovascular (CV) disease in HIV-positive subjects. While differing in their specifics, a number of published cohort studies and clinical trials support such an association, usually relating it to recent exposure to the drug, independently of traditional predisposing factors. However, other clinical trials have failed to reveal such a relation, and have pointed to methodological differences to explain discrepancies...

BACKGROUND: Parent-offspring (PO) regression is a central tool to determine the heritability of phenotypic traits; i.e., the relative extent to which those traits are controlled by genetic factors. The applicability of PO regression to viral traits is unclear because the direction of viral transmission-who is the donor (parent) and who is the recipient (offspring)-is typically unknown and viral phylogenies are sparsely sampled. METHODS: We assessed the applicability of PO regression in a realistic setting using Ornstein-Uhlenbeck simulated data on phylogenies built from 11,442 Swiss HIV Cohort Study (SHCS) partial pol sequences and set-point viral load (SPVL) data from 3293 patients...

The acquired immune deficiency syndrome (AIDS) epidemic was first recognized in 1981, and it quickly became a public health emergency. In a 1987 paper in the American Journal of Epidemiology (Am J Epidemiol. 1987;126(2): 310-318), Richard Kaslow et al. described the launch of the Multicenter AIDS Cohort Study (MACS), a cohort study of homosexual men in 4 US cities, the purpose of which was to better understand the natural history of AIDS and its determinants. The MACS enrolled participants through a range of community contacts...

Background: HIV-1 persists in latently infected resting CD4+ T cells (rCD4), posing a major barrier to curing HIV-1 infection. Previous studies have quantified this pool of latently infected cells in Americans; however, no study has quantified this reservoir in sub-Saharan Africans, who make up the largest population of HIV-1-infected individuals globally. Methods: Peripheral blood was collected from 70 virally suppressed HIV-1-infected individuals from Rakai District, Uganda, who had initiated antiretroviral therapy (ART) during chronic infection...

BACKGROUND: The introduction of direct-acting antivirals (DAAs) created a major paradigm shift in the treatment of chronic hepatitis C. Currently, there is little "real-world" data regarding hepatitis C virus (HCV) treatment outcomes in the human immunodeficiency virus (HIV)/HCV-coinfected population. METHODS: This retrospective cohort study examined HCV treatment outcomes of HIV/HCV-coinfected patients at a large, urban, Ryan White-funded clinic caring for an underserved population...

Household air pollution (HAP) and chronic HIV infection are each associated with significant respiratory morbidity. Little is known about relationships between HAP and respiratory symptoms among people living with HIV. The objective of this study was to investigate the relationship between cooking fuel type and chronic respiratory symptoms in study participants from the Uganda AIDS Rural Treatment Outcomes Study. Study participants were enrolled at the time of antiretroviral therapy initiation and seen quarterly from 2005 to 2014 for health-focused questionnaires, CD4 count and HIV viral load...

There are limited documents about HIV patients switched to second-line antiretroviral therapy (ART) in resource-limited countries. We aimed to assess the efficacy of second-line ART for HIV patients following first-line ART failure. This was a cohort study of HIV/AIDS patients with first-line ART treatment failure switched to second-line ART between January 2004 and March 2014, who followed for at least 12 months after switching. Fifty of studied patients (85%) were treated with regimens containing lopinavir/ritonavir (Kaletra) and nine of them (15%) treated with other regimes...

INTRODUCTION: The transition from paediatric to adult care poses risks to the health of young adults living with HIV if unsuccessful, including interruptions in care and poor health outcomes. Evolving best practices in HIV healthcare transition should ideally be informed by real-world qualitative and quantitative clinical healthcare transition outcomes. There has been a recent proliferation of HIV healthcare transition outcome research, largely from Europe and North America. METHODS: A literature search was undertaken using the online databases PubMed, Web of Science, and Google Scholar...
