: Improved survival among HIV-1 infected individuals with the advent of antiretroviral therapy has clearly led to a greater prevalence of non-infectious complications. One of the most devastating sequelae in these individuals is the development of pulmonary arterial hypertension (PAH). Various epidemiological studies suggest a worse survival of HIV-PAH patients when compared to other forms of PAH. Given that only a subset and not all HIV-infected individuals develop HIV-PAH, suggests that an additional second hit of genetic or environmental triggers is needed for the development of PAH...

: Chronic elevation of plasma cytokines is a key feature of HIV infection. The physiological consequence of this response to infection and its role in HIV persistence is not fully understood. Here, we show that common gamma chain (γc)-cytokines induce both proliferation and expression of T cell exhaustion markers in a mTOR-dependent fashion, suggesting a possible therapeutic target that, if inhibited, could diminish HIV reservoir expansion, persistence, and resistance to immune surveillance.

Numerous PrEP guidelines recommend 3 monthly screening for gonorrhoea and chlamydia. To quantify the risk of antimicrobial resistance this may induce, we conducted a literature review of the incidence of gonorrhoea and chlamydia in PrEP studies that conducted 3 site, 3 monthly screening. We found that screening could result in macrolide consumption rates that exceed those in high macrolide consumption populations where consumption has been strongly associated with macrolide resistance.

OBJECTIVE: Recent studies reported lower human papillomavirus 16 (HPV16) prevalence in cervical precancer among African American than Caucasian women in the general population. We assessed this relationship in women with HIV. DESIGN: Women living with or at risk for HIV in the Women's Interagency HIV Study were followed semi-annually with Pap tests, colposcopy/histology (if indicated), and collection of cervicovaginal lavage samples for HPV testing by PCR. Racial and ethnic groups were defined using genomic Ancestry Informative Markers (AIMs)...

BACKGROUND: Kaposi's sarcoma (KS), the most common AIDS related cancer, represents a major public concern in resource-limited countries. Single nucleotide polymorphisms within the Interferon lambda 3/4 region (IFNL3/4) determine the expression, function of IFNL4, and influence the clinical course of an increasing number of viral infections. OBJECTIVES: To analyze whether IFNL3/4 variants are associated with susceptibility to AIDS-related KS among men who have sex with men (MSM) enrolled in the Swiss HIV Cohort Study (SHCS)...

OBJECTIVE: Reduced bone mineral density (BMD) is a frequent comorbidity observed in people living with HIV (PLHIV). We aimed to determine the prevalence of reduced BMD and its associated factors among young PLHIV men, virologically controlled by combined antiretroviral therapy (cART). DESIGN: Bicentric cross-sectional study. METHODS: We selected men, aged<50 years, treated by cART, with HIV-RNA<50 copies/mL. BMDs of lumbar spine and hip were measured by dual-energy X-ray absorptiometry (DXA)...

: The widespread use of antiretroviral treatment (ART) results in a significant improvement in immunological condition of people living with HIV (PLWH), that nevertheless experience a significantly increased risk to develop non-Hodgkin lymphoma compared with general population. Despite many literature observations regarding Multiple Myeloma (MM) in PLWH, a consensus on its relevance in HIV infection does not exist.A number of large population studies on Multiple Myeloma in PLWH gave contrasting results, fluctuating from increased standardized incidence ratios (SIRs) to the lack of observed cases of MM...

: It is recommended that HIV-infected individuals receive annual influenza vaccination due to their high susceptibility to influenza infection, especially among females. However, there have been few studies investigating sex-related responses to influenza vaccine in antiretroviral (ART)-treated HIV-infected subjects. In this study, 26 aviremic ART-treated HIV-infected subjects and 16 healthy controls were enrolled in the current study. Blood was collected prior to vaccination (D0), on days 7-10 (D7), and on days 14-21 (D14) following administration of the 2013-2014 seasonal influenza vaccine...

OBJECTIVE: The effects of in-utero HIV-exposure on infectious morbidity and mortality in settings with universal maternal treatment and high breastfeeding rates are unclear. Further, the benefits of exclusive feeding options have not been assessed in the Option B+ era. We investigated these in two African settings with high breastfeeding uptake and good HIV treatment infrastructure during the first year of life. METHODS: Cox regression with time-changing variables in a birth cohort of 749 HIV-exposed uninfected and HIV-unexposed uninfected infants from Cape Town, South Africa and Jos, Nigeria...
