Barcelona Institute for Global Health (ISGlobal) Paves the Way for Breakthrough Solutions

In a pioneering effort to address the intersecting challenges of malaria and HIV in pregnant women, the Barcelona Institute for Global Health (ISGlobal) has conducted the MAMAH clinical trial, offering a glimmer of hope for enhanced maternal health. Supported by the European & Developing Countries Clinical Trials Partnership (EDCTP), this study sheds light on the efficacy of dihydroartemisinin and piperaquine (DHA-PPQ) as a safe preventive treatment, particularly tailored for pregnant women living with HIV. The comprehensive results, recently published in the Lancet Infectious Diseases, underscore the potential to positively impact the lives of nearly one million pregnant women facing the dual burden of malaria and HIV annually.

The Vulnerability Conundrum

Pregnant women, inherently more susceptible to malaria infection, encounter a unique challenge when living with HIV. The conventional preventive treatment, relying on sulphadoxine and pyrimethamine (SP), presents a significant hurdle due to its incompatibility with co-trimoxazole (CTX), an antibiotic crucial for preventing bacterial infections in HIV patients. This predicament leaves pregnant women with HIV—the most vulnerable group—insufficiently shielded against the perils of malaria.

• Critical Imbalance: Pregnant women living with HIV, facing heightened vulnerability to malaria, paradoxically lack adequate protection due to drug incompatibility.
• Compromised Preventive Measures: The commonly recommended sulphadoxine and pyrimethamine (SP) treatment clashes with co-trimoxazole (CTX), leaving a gap in protection for this high-risk population.

ISGlobal’s Endeavor: The MAMAH Project

In response to this critical health challenge, ISGlobal initiated the MAMAH project, led by Clara Menéndez, director of ISGlobal’s Maternal, Child and Reproductive Health Initiative. The primary goal was to evaluate the safety and efficacy of alternative drugs, DHA-PPQ, for preventing malaria during pregnancy in women living with HIV. The trial, conducted in Gabon and Mozambique, involved over 600 pregnant women who were concurrently receiving CTX and antiretroviral treatment.

• Research Objective: MAMAH sought to assess the viability of dihydroartemisinin and piperaquine (DHA-PPQ) as a preventive measure against malaria during pregnancy for women living with HIV.
• Geographical Reach: The trial spanned regions with a high prevalence of both malaria and HIV—Gabon and Mozambique—reflecting the global relevance of the study.

Unlocking Protective Potential

While the study did not reveal a significant difference in malaria infection rates at the time of delivery, it showcased compelling outcomes regarding the use of DHA-PPQ during pregnancy. The group receiving DHA-PPQ exhibited a nearly eightfold reduction in the risk of developing clinical malaria throughout pregnancy compared to the placebo group. Moreover, the risk of infection itself was nearly halved in the DHA-PPQ group.

• Significant Risk Reduction: DHA-PPQ demonstrated an almost eightfold decrease in the risk of clinical malaria during pregnancy, highlighting its efficacy.
• Broad Antiretroviral Compatibility: DHA-PPQ’s effectiveness extended across various antiretroviral treatments, addressing concerns about treatment compatibility.

Ensuring Holistic Health Outcomes

Beyond its efficacy in malaria prevention, DHA-PPQ demonstrated a commendable safety profile. No serious side effects were observed, and crucially, there was no adverse impact on mother-to-child transmission of HIV. This addresses a vital concern, ensuring that the proposed preventive measure does not inadvertently jeopardize other aspects of maternal and child health.

• Safety Assurance: DHA-PPQ showcased a favorable safety profile, alleviating concerns about potential adverse effects on pregnant women or the transmission of HIV to the child.
• Holistic Impact: The study’s findings underscore the comprehensive approach needed to safeguard maternal and child health, extending beyond disease prevention.

Implications and Future Prospects

The conclusive results of the MAMAH clinical trial position DHA-PPQ as a beacon of hope for pregnant women living with HIV. This breakthrough not only addresses a critical health disparity but also has far-reaching implications for global health strategies.

• Strategic Implications: The findings advocate for the inclusion of DHA-PPQ in preventive strategies for pregnant women with HIV, potentially reshaping global health protocols.
• Global Health Impact: The potential integration of DHA-PPQ could significantly impact the lives of pregnant women worldwide, fostering a healthier future for mothers and children.

Conclusion

In conclusion, the MAMAH clinical trial stands as a testament to the transformative power of research in healthcare. The dedication of the research team, the strategic vision of ISGlobal, and the promising outcomes of DHA-PPQ collectively illuminate a path forward. This paradigm shift not only addresses a critical health disparity but also exemplifies the potential for research to shape a brighter and healthier tomorrow. As we embrace these findings, we usher in an era where maternal health is fortified, vulnerabilities are addressed, and hope becomes a tangible reality for pregnant women living with HIV.
