Progress and Emerging Challenges in Preventing Mother-to-Child Transmission

Area of Science:

• Public Health
• Infectious Diseases
• Global Health

Background:

• Significant disparity exists in preventing mother-to-child HIV transmission (PMTCT) between sub-Saharan Africa and other regions.
• Most sub-Saharan African countries utilize less effective single-dose nevirapine (NVP) for PMTCT, unlike triple antiretroviral regimens used elsewhere.
• Concerns regarding unacceptable resistance levels necessitate a review of current PMTCT strategies in sub-Saharan Africa.

Purpose of the Study:

• To review current PMTCT strategies in sub-Saharan Africa.
• To summarize programmatic and evidence-based reasons for adopting standardized long-course, triple-drug prophylaxis for MTCT prevention.
• To advocate for enhanced efforts in minimizing breast milk transmission of HIV.

Main Methods:

• This is a review article, summarizing existing programmatic and evidence-based data.
• Comparative analysis of PMTCT regimens used in sub-Saharan Africa versus other global regions.
• Examination of antiretroviral treatment program effectiveness in resource-constrained settings.

Main Results:

• Single-dose NVP regimens in sub-Saharan Africa are less effective and lead to higher resistance compared to triple antiretroviral regimens.
• Standardized approaches in antiretroviral treatment programs have demonstrated effectiveness in resource-constrained settings.
• Successful PMTCT outcomes comparable to high-income countries are achievable with standardized, long-course, triple-drug regimens in sub-Saharan Africa, given adequate infrastructure.

Conclusions:

• A standardized approach using long-course, triple-drug regimens for MTCT prophylaxis is recommended for sub-Saharan Africa.
• Enhancing strategies to minimize breast milk transmission of HIV is crucial.
• Effective PMTCT is achievable in resource-constrained settings with appropriate programmatic capacity and standardized regimens.
