INTRODUCTION: A large and increasing number of HIV-infected women are conceiving on antiretroviral treatment (ART). While most antiretrovirals are considered safe in pregnancy, monitoring for rare pregnancy and infant adverse outcomes is warranted. METHODS: We conducted a retrospective secondary analysis nested within a clinical trial of infant cotrimoxazole vs. placebo prophylaxis in Botswana (the Mpepu Study). Infants were examined at birth, and at least every 3 months through 18 months of age...

Background: We conducted unlinked cross-sectional population-based surveys in Northern Uganda before and after antiretroviral therapy (ART) provision (including Option B+ [lifelong ART for pregnant/breast-feeding women]) at a local primary care facility (Lira Kato Health Centre [HC]). Prior to decentralisation, people travelled 56-76 km round-trip for ART; we aimed to evaluate changes in uptake of HIV-testing, ART coverage and access to ART following decentralisation. Methods: A total of 2124 adults in 1351 households in two parishes closest to Lira Kato HC were interviewed using questionnaires between March and April 2013 and 2123 adults in 1229 households between January and March 2015...

BACKGROUND: Reforms to the legal status of medical and non-medical cannabis are underway in many jurisdictions, including Canada, as are renewed efforts to scale-up HIV treatment-as-prevention (TasP) initiatives. It has been suggested that high-intensity cannabis use may be associated with sub-optimal HIV treatment outcomes. Thus, using data from a setting with a community-wide treatment-as-prevention (TasP) initiative coinciding with increasing access to medical cannabis, we sought to investigate the possible impact of high-intensity cannabis use on HIV clinical outcomes...

The physiological changes accompanying inflammation may alter the pharmacokinetics (PK) of certain medications. Individuals infected with HIV have chronically elevated inflammatory markers despite viral suppression following effective antiretroviral therapy (ART), as well as age-related inflammation. Understanding the potential clinical implications of inflammation on the PK of medications is important for understanding dose-response relationships and necessitates future research. Areas covered: An extensive literature search was carried out using PubMed and associated bibliographies to summarize the current state of knowledge regarding altered PK in response to inflammation and its application to the field of HIV...

Tuberculosis (TB) with human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome represents the most common infectious diseases worldwide. Anti-TB drugs are used concurrently with antiretroviral drug for treatment of TB-HIV co-morbidities. Due to lower risk of interaction with protease inhibitors, rifabutin is preferred over rifampicin in treatment of HIV and TB co-morbidity. A simple and specific liquid chromatography tandem mass spectrometry method was developed for quantification of rifabutin (RBT) and lopinavir (LPV) simultaneously in human plasma...

Evidence has been accumulating in recent years that individuals with HIV who are effectively treated with antiretroviral drugs are highly unlikely to transmit the virus to their sexual partners. This approach has great potential to contribute to ongoing prevention efforts and has been termed 'treatment as prevention'. International political momentum has been building in recent years to attempt to significantly reduce new HIV infections globally and end the epidemic by 2030. In pursuit of such aims a number of local health authorities and communities have adopted intensified 'test and treat' strategies to quickly diagnose infections and reduce the risk of onward transmission through an immediate offer of treatment...

BACKGROUND: In all settings, there are challenges associated with safely treating patients with multimorbidity and polypharmacy. The need to characterise, understand and limit harms resulting from medication use is therefore increasingly important. Drug-drug interactions (DDIs) are prevalent in patients taking antiretrovirals (ARVs) and if unmanaged, may pose considerable risk to treatment outcome. One of the biggest challenges in preventing DDIs is the substantial gap between theory and clinical practice...

Background: Integrase inhibitors have shown better tolerability than other drugs in clinical trials, but some post-marketing data have suggested potential differences among them. Aims: We compared rates and reasons for discontinuation of raltegravir-, elvitegravir- and dolutegravir-based regimens in a large cohort of HIV-infected patients. Methods: Retrospective analysis of a prospectively followed cohort including all antiretroviral-naive and all virologically suppressed antiretroviral-experienced patients prescribed a first regimen containing raltegravir, elvitegravir or dolutegravir with at least one follow-up visit...

OBJECTIVES: Antiretroviral therapy (ART) has been associated with unfavourable lipid profile changes and increased risk of cardiovascular disease (CVD). With a growing population on ART in South Africa, there has been concern about the increase in noncommunicable diseases such as CVD. We determined risk factors associated with increased total cholesterol (TC) in a large cohort on ART and describe the clinical management thereof. METHODS: We conducted an observational cohort study of ART-naïve adults initiating standard first-line ART in a large urban clinic in Johannesburg, South Africa...

BACKGROUND: Adhering 95% and above of antiretroviral therapy reduces the rate of disease progression and death among people's living human immunodeficiency virus. Though manifold factors have reported as determinant factors of antiretroviral therapy adherence status, perhaps determinants of non-adherence differ up on the activities of patients in the study setting. METHODS: An institution based unmatched case-control study was conducted in Aksum town. Individuals who had a 6-month follow-up with complete individual information were included in the study...

North Karnataka is one of the regions with the high prevalence of HIV+ individuals. Bijapur is a district in North Karnataka with high prevalence as per fact sheets of NACO of March 2012. Better awareness, access to health care, and antiretroviral therapy have improved survival and increase in number of people living with HIV/AIDS (PLHA). Improved survival has increased their attendance to hospitals with variety of surgical problems, some known and some less known. The percentage of HIV+ individuals was 1.64 % among all admissions...

BACKGROUND: Human endogenous retroviruses (HERVs) are genomic sequences of retroviral origin which were believed to be integrated into germline chromosomes millions of years ago and account for nearly 8% of the human genome. Although mostly defective and inactive, some of the HERVs may be activated under certain physiological and pathological conditions. While no drugs are designed specifically targeting HERVs, there are a panel of antiretroviral drugs designed against the human immunodeficiency virus and approved by the Federal Drug Administration (FDA)...

Background: Treatment with latency reversing agents (LRA) enhances HIV-1 transcription in vivo but only leads to modest reductions in the size of the reservoir, possibly due to insufficient immune-mediated elimination of infected cells. We hypothesized that a single drug molecule - a novel toll-like receptor 9 (TLR9) agonist, MGN1703 - could function as an enhancer of innate immunity and an LRA in vivo. Methods: We conducted a single-arm, open-label study, where 15 virologically suppressed HIV-1 infected individuals on antiretroviral therapy received 60 mg MGN1703 s...

To inform the level of attention to be given by antiretroviral therapy (ART) programs to HIV drug resistance (HIVDR), we used an individual-level model to estimate its impact on future AIDS deaths, HIV-incidence and ART program costs in sub-Saharan Africa (SSA) for a range of program situations. We applied this to SSA through the Spectrum-Goals model. In a situation in which current levels of pre-treatment HIVDR are over 10% (mean 15%), 16% of AIDS deaths (890,000 deaths) , 9% of new infections (450,000) and 8% ($6...

Background: Antiretrovirals (ARVs) affect bone density and turnover, but their effect on risk of fractures and osteonecrosis of the femoral head is less understood. We investigated if exposure to ARVs increases the risk of both bone outcomes. Methods: EuroSIDA participants were followed to assess fractures and osteonecrosis. Poisson regression identified clinical, laboratory and demographic predictors of either bone outcome. Ever, current and cumulative exposures to ARVs were assessed...
