To identify factors (including exposure to specific antiretroviral drugs) associated with severe vitamin D deficiency (VDD) in HIV-infected individuals and to explore the effects of severe VDD and antiretroviral drug exposure on serum alkaline phosphatase (ALP) as surrogate marker of bone turnover. ⋯ Efavirenz was associated with severe VDD, a condition associated with multiple adverse health outcomes, and efavirenz and tenofovir with increased ALP. The clinical significance of these findings requires further investigation, given the widespread use of efavirenz and tenofovir in first-line combination antiretroviral therapy.

To investigate the survival outcomes for non-Hodgkin lymphoma (NHL) in HIV-infected vs. uninfected patients from the same integrated healthcare system, and to identify prognostic factors for HIV-related NHL in the era of combined antiretroviral therapy. ⋯ HIV-infected patients with NHL in the combined antiretroviral therapy era continue to endure substantially higher mortality compared with HIV-uninfected patients with NHL. Better management and therapeutic approaches to extend survival time for HIV-related NHL are needed.

The Middle East and North Africa (MENA) region continues to be perceived as a region with very limited HIV epidemiological data, raising many controversies about the status of the epidemic in this part of the world. The objective of this review and synthesis was to address the dearth of strategic interpretable data on HIV in MENA by delineating a data-driven overview of HIV epidemiology in this region. ⋯ Although they do not provide complete protection against HIV spread, near universal male circumcision and possibly the prevailing sexually conservative cultural norms seemed to have played so far a protective role in slowing and limiting HIV transmission in MENA relative to other regions. If the existing social and epidemiological context remains largely the same, HIV epidemic transmission is likely to remain confined to high-risk populations and their sexual partners, in addition to exogenous exposures. HIV prevention efforts in this region, which continue to be stymied by stigma associated with HIV/AIDS and related risk behaviors, need to be aggressively expanded with a focus on controlling HIV spread along the contours of risk and vulnerability. There is still a window of opportunity to control further HIV transmission among high-risk groups in MENA that, if missed, may entail a health and socioeconomic burden that the region, in large part, is unprepared for.

Despite World Health Organization recommendations, concerns about promoting resistance have impeded implementation of isoniazid preventive therapy (IPT) for tuberculosis (TB). We describe characteristics of TB in individuals previously exposed to IPT as part of 'Thibela TB', a cluster-randomized trial of community-wide IPT in gold miners in South Africa. ⋯ TB after recent IPT has prevalence of drug resistance similar to background and treatment outcomes typical of this setting. These data support wider implementation of IPT.
