Description

Human Immunodeficiency Virus (HIV) is a global public health challenge with significant implications for maternal and child health. Breastfeeding, although critical for infant nutrition and immunity, presents unique risks in the context of HIV due to potential vertical transmission. Understanding the interplay between HIV and breastfeeding is essential for crafting effective strategies to optimize maternal and infant health outcomes while mitigating risks. This article examines the effects of HIV on breastfeeding, the mechanisms of HIV transmission through breast milk, and the clinical considerations for managing breastfeeding in HIV-positive mothers. HIV transmission via breastfeeding occurs when the virus present in an HIV-positive mother’s breast milk is ingested by the infant. Several factors influence the likelihood of transmission. Higher viral loads in breast milk correlate with increased transmission risk. Viral replication in mammary glands contributes to the presence of HIV in milk. HIV-associated immune suppression can increase susceptibility to infections, including mastitis, which can hinder milk production. HIV-positive mothers often experience nutritional deficits due to increased metabolic demands and coexisting infections, potentially affecting milk quality and quantity. The stigma of HIV can contribute to anxiety, depression, and stress, which may influence breastfeeding practices and adherence to medical recommendations. Without interventions, breastfeeding contributes to 5%-20% of postnatal HIV transmission.

Effective ART during pregnancy and breastfeeding lowers viral load to undetectable levels, dramatically reducing transmission risk to below 1%. Antiretroviral prophylaxis for infants during breastfeeding further reduces the risk of postnatal HIV acquisition. WHO recommends exclusive breastfeeding for the first six months of life for HIV-positive mothers on ART, followed by complementary feeding, given its nutritional and immunological benefits. In settings where safe and affordable alternatives are available, replacement feeding (formula or donor milk) is an option. However, in low-resource settings, where alternatives may pose risks of malnutrition and infections, breastfeeding with ART is the preferred strategy. Lack of access to clean water and adequate sanitation can make formula feeding unsafe, increasing the risk of diarrheal diseases and malnutrition. Pasteurized donor milk offers a viable alternative in resource-rich settings, eliminating HIV transmission risk while retaining nutritional and immunological benefits.

Breastfeeding practices are deeply rooted in cultural and social contexts, making it essential to consider ethical and cultural factors when formulating mothers should receive accurate information and support to make autonomous decisions about breastfeeding. Tailoring interventions to align with local cultural norms and practices can improve acceptance and adherence. Combating stigma associated with both HIV and formula feeding requires targeted community education and advocacy. Developing long-acting ART formulations may enhance adherence and reduce transmission risks. Exploring maternal and infant HIV vaccines could provide additional preventive measures. Identifying biomarkers of breast milk transmission risk can refine risk stratification and guide interventions. Studying real-world implementation of WHO guidelines can inform best practices and optimize outcomes in diverse settings.

Conclusion

The interplay between HIV and breastfeeding presents complex challenges and opportunities. While breastfeeding is vital for infant survival and development, the risk of HIV transmission necessitates careful management. Advances in ART have significantly mitigated these risks, allowing many HIV-positive mothers to safely breastfeed. However, continued efforts are needed to address barriers to ART access, enhance education and support, and tailor interventions to diverse cultural and resource contexts. By integrating clinical, public health, and ethical perspectives, we can ensure better health outcomes for HIV-positive mothers and their children.
