Carriage of antimicrobial-resistant Enterobacterales among pregnant women and newborns in Amhara, Ethiopia.

OBJECTIVES: Infections are one of the most common causes of neonatal mortality, and maternal colonization has been associated with neonatal infection. In this study, we sought to quantify carriage prevalence of extended-spectrum-beta-lactamase (ESBL) -producing and carbapenem-resistant Enterobacterales (CRE) among pregnant women and their neonates and to characterize risk factors for carriage in rural Amhara, Ethiopia. METHODS: We conducted a prospective cohort study nested in the Birhan field site. We collected rectal and vaginal samples from 211 pregnant women in their third trimester and/or during labor/delivery and perirectal or stool samples from 159 of their neonates in the first week of life. RESULTS: We found that carriage of ESBL-producing organisms was fairly common (women: 22.3%, 95% CI: 16.8-28.5; neonates: 24.5%, 95% CI: 18.1-32.0), while carriage of CRE (women: 0.9%, 95% CI: 0.1-3.4; neonates: 2.5%, 95% CI: 0.7-6.3) was rare. Neonates whose mothers tested positive for ESBL-producing organisms were nearly twice as likely to also test positive for ESBL-producing organisms (38.7% vs 21.1%, P-value = 0.06). Carriage of ESBL-producing organisms was also associated with Woreda (district) of sample collection and recent antibiotic use. CONCLUSION: Understanding carriage patterns of potential pathogens and antibiotic susceptibility among pregnant women and newborns will inform local, data-driven recommendations to prevent and treat neonatal infections.

Setting a research agenda to advance maternal, newborn, and child health in Ethiopia: An adapted CHNRI prioritization exercise.

Background: Critical to the improvement of maternal, newborn, and child health (MNCH) in Ethiopia - where 14 000 mothers die from pregnancy-, childbirth-, or postpartum-related complications each year - is high-quality research and its effective translation into policy and practice. While Ethiopia has rapidly expanded the number of institutions that train and conduct MNCH research, the absence of a shared research agenda inhibits a coordinated approach to inform critical MNCH policy needs. The HaSET Maternal and Child Health Research Program (MCHRP) conducted a mixed methods formative assessment and prioritization exercise to guide investments in future MNCH research in Ethiopia. Methods: We adapted the Child Health and Nutrition Research Initiative (CHNRI) method, soliciting 56 priority research questions via key informant interviews. Through an online survey, experts scored these on their ability to generate new, actionable evidence that could inform more effective and equitable MNCH programs in Ethiopia. At a workshop in Addis Ababa, experts scored the questions by answerability and ethics, usefulness, disease burden reduction, and impact on equity. Research priority scores were calculated for both the online survey and workshop scoring and averaged to attain a ranked priority list. We validated and contextualized the results by conducting consensus-building discussions with MNCH experts and two community workshops. In total, approximately 100 participants were involved. Results: Average research priority scores ranged from 58.4 to 83.7 out of 100.0. The top identified research priorities speak to critical needs in the Ethiopian context: to improve population coverage of proven interventions like integrated community case management (ICCM), family integrated newborn care, and kangaroo mother care (KMC); to better understand the determinants of outcomes like home deliveries, immunization drop-out, and antenatal and postpartum care-seeking; and to strengthen health system and workforce capabilities. Conclusions: This exercise expanded on the CHNRI methodology by comparing prioritization across different audiences, formats, and criteria. Agreement between both scoring rounds and consensus-building discussions was strong, demonstrating the reliability of the CHNRI method. By sharing this research priority list broadly among researchers, practitioners, and donors, we aim to improve coordinated MNCH evidence generation and translation into policy in Ethiopia.
