Fetal Alcohol Spectrum Disorders–a Case-Control Study from India

Background: Maternal alcohol abuse during pregnancy can lead to fetal neurotoxicity and fetal alcohol spectrum disorder (FASD). Aims: To compare the clinical features and neurobehavioral profiles of children exposed to alcohol during pregnancy with controls. Read More

Food Supplementation as an Incentive to Improve Pre-antiretroviral Therapy Clinic Adherence in HIV-Positive Children–Experience from Eastern India

Objective: To evaluate the importance of food supplementation as incentive in improving preantiretroviral therapy (pre-ART) adherence, and second its impact on health of HIV-infected children by a clinic-based observational study. Methods: HIV-seropositive children aged between 2 and 12 years were followed-up sequentially for 2 years without and with food supplementation, respectively, with monitoring of disease parameters. The outcome morbidity parameters were compared and correlated. Read More

Recombinant Human Granulocyte Colony-stimulating Factor in Preterm Neonates with Sepsis and Relative Neutropenia: a Randomized, Single-Blind, Non-placebo-controlled Trial

We performed a prospective, randomized, single-blind, non-placebo-controlled trial on preterm (<37 weeks) neonates (birth weight <2000g) with sepsis and absolute neutrophil counts (ANC) <5000 cells mm–3 to study the effect of recombinant human granulocyte colony-stimulating factor (rhG-CSF) on all-cause-neonatal mortality and hematological parameters (total leucocyte (TLC, ANC, absolute monocyte and absolute platelet counts).

Evolution of lipid levels in HIV-infected children treated or not with HAART in Abidjan, Cote d’Ivoire

Objective: To describe lipid levels in antiretroviral (ARV)-naïve HIV-infected Ivorian children and assess their evolution after ARV-treatment initiation. Methods: Lipid concentrations were assessed at baseline and at least 6 months later in 93 children. Fifty-six children initiated ARV treatment at baseline, and 37 remained untreated. Read More

Immunotherapy: Low-dose IL-2 therapy expands human regulatory T cell populations

Nature Reviews Immunology 12, 6 (2012).
doi:10.1038/nri3140

Interleukin-2 (IL-2) promotes both effector T and regulatory T (TReg) cell responses, but it is believed that TReg cells may be more sensitive to IL-2. Two recent studies found that low-dose IL-2 therapy preferentially expands TReg cell populations in
