Introduction: Two recent studies have highlighted low rates of virological response to once daily nevirapine containing combination antiretroviral therapy (CART) in treatment naïve HIV-1 infected subjects.
Aim: We assessed factors associated with treatment responses in a cohort of HIV-1 infected, therapy naïve individuals, commencing nevirapine CART with two nucleoside reverse transcriptase inhibitors (NRTI) containing either lamivudine or emtricitabine.
Results: Between January 2002 and 2006, 173 subjects (80 female) met the study inclusion criteria. All subjects initially commenced on twice daily nevirapine with six different NRTI backbones. Mean follow up was 802 days. 49 (28%) subjects switched to once daily nevirapine, 23 (13%) within the first year. After 48 weeks of therapy, HIV RNA was < 50 copies/mL in 154/173 subjects (89%). A trend was observed towards improved virological outcome (HIV RNA < 50 copies/mL) and switching to once daily nevirapine during the first year of therapy (p=0.051).
Conclusion: Whilst awaiting the results of prospective studies assessing once daily nevirapine, our data describe high treatment success rates and good safety responses when switching to once daily nevirapine.

Article Synopsis
- The study explores the impact of very early antiretroviral therapy (ART) on infants born with HIV-1, aiming to limit HIV reservoirs for potential treatment-free remission.
- Conducted across 30 clinics in 11 countries, infants were categorized into two cohorts based on maternal HIV treatment, starting ART within 48 hours of birth to monitor virological suppression and safety outcomes.
- Results from 440 infants (54 with confirmed HIV-1) showed that a significant majority received effective study ART, indicating early intervention may positively affect health outcomes in these infants.
Uptake of selected antiretrovirals by pepper (Capsicum annum), radish (Raphanus sativus), and ryegrass (Lolium perenne) grown on two contrasting soils and fertilized with human urine-derived fertilizers.

The use of urine-derived fertilizers has several economic and environmental advantages. However, there is concern that pharmaceutical residues present in urine could enter the food chain after plant uptake and pose potential risks to human and animal health. A pot experiment was conducted to evaluate the uptake of nine target antiretroviral drugs (ARVDs) by pepper (Capsicum annum), ryegrass (Lolium perenne) and radish (Raphanus sativus) grown in two soils of contrasting texture and organic matter content and fertilized with stored urine, nitrified urine concentrate (NUC), and struvite.

Objectives: Because NRTIs can have fetal toxicities, we evaluated a perinatal NRTI-sparing strategy to prevent perinatal HIV transmission. Our primary objective was to determine the proportion maintaining a viral load (VL) of <50 copies/mL up to delivery on darunavir/ritonavir monotherapy, without requiring treatment intensification.
Methods: In a one-arm, multicentre Phase 2 clinical trial, eligible patients in the first trimester of pregnancy on ART with plasma VL < 50 copies/mL received maintenance monotherapy with darunavir/ritonavir, 600/100 mg twice daily.
Antiretroviral postnatal prophylaxis to prevent HIV vertical transmission: present and future strategies.

Introduction: Maternal antiretroviral therapy (ART) with viral suppression prior to conception, during pregnancy and throughout the breastfeeding period accompanied by infant postnatal prophylaxis (PNP) forms the foundation of current approaches to preventing vertical HIV transmission. Unfortunately, infants continue to acquire HIV infections, with half of these infections occurring during breastfeeding. A consultative meeting of stakeholders was held to review the current state of PNP globally, including the implementation of WHO PNP guidelines in different settings and identifying the key factors affecting PNP uptake and impact, with an aim to optimize future innovative strategies.

Artemisinin-based combination therapies (ACTs) are the primary treatment for malaria. It is essential to characterize the pharmacokinetics (PKs) and pharmacodynamics (PDs) of ACTs in vulnerable populations at risk of suboptimal dosing. We developed a population PK/PD model using data from our previous study of artemether-lumefantrine in HIV-uninfected and HIV-infected children living in a high-transmission region of Uganda.
