Multicenter Study Observational Study
Effects of syndemics on HIV viral load and medication adherence in the multicentre AIDS cohort study.
The objective of this study is to determine associations between intertwining epidemics (syndemics) and HIV medication adherence and viral load levels among HIV-positive MSM and to test whether adherence mediates the relationship between syndemics and viral load. ⋯ Effectively lowering viral load levels among MSM has implications for both HIV/AIDS prevention and care. Our findings suggest that integrating substance use interventions, mental healthcare and sexual risk prevention into standard HIV care may be necessary to optimize treatment and Treatment as Prevention (TasP) models.

Randomized Controlled Trial Multicenter Study
Tuberculosis incidence after 36 months' isoniazid prophylaxis in HIV-infected adults in Botswana: a posttrial observational analysis.
Thirty-six months of isoniazid preventive therapy (36IPT) was superior to 6 months of IPT (6IPT) in preventing tuberculosis (TB) among HIV-infected adults in Botswana. We assessed the posttrial durability of this benefit. ⋯ The benefit of 36IPT for TB prevention declined posttrial in this cohort. Adjunctive measures are warranted to prevent TB among HIV-infected persons receiving long-term ART in TB-endemic settings.

Preexposure prophylaxis for the prevention of HIV transmission to women.
The Food and Drug Administration (FDA) recently approved a new preexposure prophylaxis (PrEP) indication for emtricitabine/tenofovir for men and women, allowing a new effective HIV prevention intervention. Recent clinical trials have demonstrated the efficacy of PrEP in reducing the risk of HIV acquisition among women. Its efficacy depends largely on adherence. ⋯ HIV-uninfected women in serodiscordant couples seeking conception may prove to be an ideal population for PrEP. Periconceptional PrEP in highly motivated couples could be not only effective but also affordable and feasible. In order to make PrEP accessible to those populations most vulnerable to HIV infection, the following steps need to occur: PrEP needs to be affordable, particularly for those uninsured; HIV providers, primary care practitioners, and reproductive healthcare providers need to welcome PrEP as a component of their scope of practice; clinicians need to take adequate sexual histories of all their patients in order to identify those at risk and best candidates for PrEP; and identifying ways to promote adherence must include population-specific PrEP adherence interventions.

Multicenter Study
Risk factors for chronic kidney disease in a large cohort of HIV-1 infected individuals initiating antiretroviral therapy in routine care.
To examine long-term effects of antiretroviral therapy (ART) on kidney function, we evaluated the incidence and risk factors for chronic kidney disease (CKD) among ART-naive, HIV-infected adults and compared changes in estimated glomerular filtration rates (eGFR) before and after starting ART. ⋯ ART was associated with reduced CKD risk in association with CD4 cell restoration and plasma viral load suppression, despite an increased CKD risk that was associated with initial regimens that included tenofovir and rPI.

Cerebrospinal fluid HIV escape associated with progressive neurologic dysfunction in patients on antiretroviral therapy with well controlled plasma viral load.
To characterize HIV-infected patients with neurosymptomatic cerebrospinal fluid (CSF) 'escape', defined as detectable CSF HIV RNA in the setting of treatment-suppressed plasma levels or CSF RNA more than 1-log higher than plasma RNA. ⋯ The development of neurologic symptoms in patients on ART with low or undetectable plasma HIV levels may be an indication of CSF 'escape'. This study adds to a growing body of literature regarding this rare condition in well controlled HIV infection.
