BACKGROUND: Human immunodeficiency virus (HIV) Rapid diagnostic Test (RDT) kits are the preferred assays for HIV testing in many countries. Prevention of Mother-to-Child Transmission, Know Your Status Campaigns, Blood-Safety, Voluntary Counseling and Testing are major strategies adapted to control transmission of the virus and the pivot of these interventions is either screening or diagnosing individuals through testing. There are reports of inconsistent sensitivity and specificity with whole blood and serum samples collected from the same individual...

The ANRS 12174 trial assessed the efficacy and tolerance of LPV/r versus 3TC prophylaxis administered to breastfed infants, whose HIV-infected mothers were not on ART. In this sub-study, we assessed LPV/r and 3TC pharmacokinetics to evaluate the percentage of infants with therapeutic plasma concentrations and to discuss these data in the context of a prophylactic treatment. Infants from the South African trial site underwent blood sampling for pharmacokinetic study at week 6, 26 and 38 of life. We applied a Bayesian approach to derive the 3TC and LPV pharmacokinetic parameters based on previously published pharmacokinetic models for HIV-infected children...

BACKGROUND: Understanding associations between pregnancy and HIV disease progression is critical to providing appropriate counseling and care to HIV-positive women. METHODS: From 2006-2011, women under age 40 with incident HIV infection were enrolled in an early HIV infection cohort in Kenya, Rwanda, South Africa, Uganda, and Zambia. Time-dependent Cox models evaluated associations between pregnancy and HIV disease progression. Clinical progression was defined as a single CD4 measurement <200 cells/μL, percent CD4 <14%, or category C event, with censoring at antiretroviral (ART) initiation for reasons other than prevention of mother-to-child transmission (PMTCT)...

OBJECTIVE: The evaluation of multidisplinary care about HIV positive pregnant women in the Czech Republic. DESIGN: Review. SETTINGS: Gynekologicko-porodnická klinika 1. LF UK a Nemocnice na Bulovce, Praha. METHODS: The vertical transmission of HIV infection from mother to fetus occurs most often during birth, still 1-2% of HIV-positive pregnant women will transfer the virus transplacenta. Due to careful screening for HIV during pregnancy, counselling, combination antiretroviral (cART) therapy, childbirth planning and its performance by C-section there appears a significant decrease of the virus transmission to the fetus, its occurrence is around 2%...

Background. Many countries are working to reduce or eliminate mother-to-child transmission (MTCT) of HIV. Prevention efforts have been conceptualized as steps in a cascade but cascade completion rates during and after pregnancy are low. Methods. A cross-sectional survey was performed across 26 communities in Cameroon, Cote d'Ivoire, South Africa, and Zambia. Women who reported a pregnancy within two years were enrolled. Participant responses were used to construct the PMTCT cascade with all of the following steps required for completion: at least one antenatal visit, HIV testing performed, HIV testing result received, initiation of maternal prophylaxis, and initiation of infant prophylaxis...

BACKGROUND: Despite the recent international focus on maternal and child nutrition, little attention is paid to nutrition capacity development. Although infant feeding counselling by health workers increases caregivers' knowledge, and improves breastfeeding, complementary feeding, and children's linear growth, most of the counselling in sub-Saharan Africa is primarily conducted by nurses or volunteers, and little is done to develop capacity for nutrition at the professional, organizational, or systemic levels...

BACKGROUND: Antiretroviral (ARV) interventions are used to reduce HIV viral replication and prevent mother-to-child transmission. Viral suppression relies on adherence to ARVs. METHODS: A 2-phase study was conducted using data from the Breastfeeding, Antiretrovirals, and Nutrition study. We included mothers randomized to 28 weeks of postpartum ARVs with ≥1 plasma or breastmilk specimen. All mothers who transmitted HIV to their infants from 2-28 weeks (n = 31) and 15% of mothers who did not (n = 232) were included...

BACKGROUND: Obstetric haemorrhage (OH) remains a major contributor to maternal morbidity and mortality. Blood transfusion is critical in OH management; yet, data on peripartum transfusion are lacking. A pilot study reported high rates of peripartum transfusion in a sample of South African (SA) hospitals, which was independently associated with HIV status. OBJECTIVES: To assess the incidence of peripartum transfusion in a sample of Eastern Cape, SA hospitals to evaluate generalisability of preceding study findings...

INTRODUCTION: Pre-treatment HIV drug resistance (PDR) is an increasing problem in sub-Saharan Africa. Children are an especially vulnerable population to develop PDR given that paediatric second-line treatment options are limited. Although monitoring of PDR is important, data on the paediatric prevalence in sub-Saharan Africa and its consequences for treatment outcomes are scarce. We designed a prospective paediatric cohort study to document the prevalence of PDR and its effect on subsequent treatment failure in Nigeria, the country with the second highest number of HIV-infected children in the world...

There is a clear need for effective strategies to address the factors that affect retention, or lost-to-follow-up (LTFU) and adherence to HIV care and treatment. Depression in particular may play an important role in the high rates of LTFU along the prevention of mother-to-child HIV transmission (PMTCT) cascade in sub-Saharan Africa. This study assessed the association between prenatal depression and (1) LTFU or (2) uptake of PMTCT services. As part of a randomized control trial to evaluate the effect of conditional cash transfers on retention in and uptake of PMTCT services, newly diagnosed HIV-infected women, ≤32 weeks pregnant, registering for antenatal care (ANC), in 85 clinics in Kinshasa, Democratic Republic of Congo (DRC), were recruited and followed-up until LTFU, death, transfer out, or six weeks postpartum...

INTRODUCTION: Globally, male involvement has been recognized as a priority focus area to be strengthened in PMTCT but, testing male partners for HIV in the context of preventing mother-to-child transmission remains a challenge in most low- and middle-income countries including Ethiopia. In Ethiopia even though male involvement is one of the guiding principle in testing and counseling of HIV, the magnitude of male involvement in PMTCT is not well known. The objective was to assess the magnitude of male involvement in PMTCT and associated factors among men whom their wives have ANC visit 12 months prior to the study in Gondar town, North west Ethiopia...
