چکیده
BACKGROUND In 2010, the World Health Organization (WHO) released revised guidelines for prevention of mother-to-child human immunodeficiency virus (HIV) transmission (PMTCT). We projected clinical impacts, costs, and cost-effectiveness of WHO-recommended PMTCT strategies in Zimbabwe. METHODS We used Zimbabwean data in a validated computer model to simulate a cohort of pregnant, HIV-infected women (mean age, 24 years; mean CD4 count, 451 cells/µL; subsequent 18 months of breastfeeding). We simulated guideline-concordant care for 4 PMTCT regimens: single-dose nevirapine (sdNVP); WHO-recommended Option A, WHO-recommended Option B, and Option B+ (lifelong maternal 3-drug antiretroviral therapy regardless of CD4). Outcomes included maternal and infant life expectancy (LE) and lifetime healthcare costs (2008 US dollars [USD]). Incremental cost-effectiveness ratios (ICERs, in USD per year of life saved [YLS]) were calculated from combined (maternal + infant) discounted costs and LE. RESULTS Replacing sdNVP with Option A increased combined maternal and infant LE from 36.97 to 37.89 years and would reduce lifetime costs from $5760 to $5710 per mother-infant pair. Compared with Option A, Option B further improved LE (38.32 years), and saved money within 4 years after delivery ($5630 per mother-infant pair). Option B+ (LE, 39.04 years; lifetime cost, $6620 per mother-infant pair) improved maternal and infant health, with an ICER of $1370 per YLS compared with Option B. CONCLUSIONS Replacing sdNVP with Option A or Option B will improve maternal and infant outcomes and save money; Option B increases health benefits and decreases costs compared with Option A. Option B+ further improves maternal outcomes, with an ICER (compared with Option B) similar to many current HIV-related healthcare interventions.

In Iran 8% of HIV- infected cases are women. Since most of them are young and in childbearing ages, in case of becoming pregnant and not receiving preventive measures, they can infect their child. Without Preventive measures transmission rate is 15 to 45 percent. Several factors such as sever stage of HIV and AIDS ,CD4 low count, high viral loud, acute retroviral phase, STDs, vaginal delivery, ...

BACKGROUND The World Health Organization (WHO) has called for the "virtual elimination" of pediatric HIV: a mother-to-child HIV transmission (MTCT) risk of less than 5%. We investigated uptake of prevention of MTCT (PMTCT) services, infant feeding recommendations, and specific drug regimens necessary to achieve this goal in Zimbabwe. METHODS AND FINDINGS We used a computer model to simulate a...

It is estimated globally 3.2 million children were living with HIV in 2014, that mostly in sub-Saharan Africa. However, the majority of them infected to HIV from their mothers during pregnancy, during delivery or breastfeeding (1). Antiretroviral therapy (ART) use during and after pregnancy is essential for prevention of mother-to-child transmission (PMTCT) of HIV (2). In the absence of any in...
