BACKGROUND: Mitochondrial toxicity was described in infants exposed to long-term antiretroviral regimens containing nucleoside analogues for the prevention of mother-to-child transmission of HIV. We measured the serum lactate levels in children born to HIV-1 infected African women receiving short-term antiretroviral prevention of mother-to-child transmission of HIV regimens. METHODS: A prospective study was conducted in women-child pairs from the third trimester of pregnancy to 3 months of life. The exposed group was formed by children exposed in utero to nucleoside analog antiretroviral regimens, zidovudine or zidovudine + lamivudine from 32 to 36 weeks of amenorrhea until delivery. All of these women received nevirapine single dose at the beginning of labor. The children received zidovudine during the first 7 days of life and a nevirapine single dose at day 3. The control group was formed by infants born to HIV-1-infected women who had received nevirapine single dose only and who were not exposed to nucleoside analog antiretroviral regimens. Serum lactate levels were measured at 4, 6, and 12 weeks of life by Cobas Integra 400. RESULTS: A total of 836 blood samples from 338 infants was collected (262 exposed and 76 controls). Median lactacidemia was 1.8 mmol/L (interquartile range: 1.2-2.7 mmol/L). Overall serum lactate levels > or = 2.5 mmol/L, defining hyperlactatemia, were observed in 39 of the 292 infants who had > or = 2 serum lactate measurements. The 3-month period prevalence of hyperlactatemia did not differ between the exposed group and the control group. All of the serum lactate levels returned to normal values in all of the subsequent samples. No case of symptomatic hyperlactatemia was detected during the study period. CONCLUSIONS: Increased lactate levels were identified equally in infants whose mother received short-term nucleoside analogs or nevirapine single dose for prevention of mother-to-child transmission of HIV. Although not rare, hyperlactatemia was not related to short-term exposure to nucleoside analog antiretroviral regimens. [ABSTRACT FROM AUTHOR]

Objectives: To determine if the Integrated Community-Based Health Systems-Strengthening (ICBHSS) initiative was effective in expanding health coverage, improving care quality, and reducing child mortality in Togo., Methods: Population-representative cross-sectional household surveys adapted from the Demographic Household Survey and Multiple Indicator Cluster Surveys were conducted at baseline (2015) and then annually (2016-2020) in 4 ICBHSS catchment sites in Kara, Togo. The primary outcome was under-5 mortality, with health service coverage and health-seeking behavior as secondary outcomes. Costing analyses were calculated by using "top-down" methodology with audited financial statements and programmatic data., Results: There were 10 022 household surveys completed from 2015 to 2020. At baseline (2015), under-5 mortality was 51.1 per 1000 live births (95% confidence interval [CI]: 35.5-66.8), and at the study end period (2020), under-5 mortality was 35.8 (95% CI: 23.4-48.2). From 2015 to 2020, home-based treatment by a community health worker increased from 24.1% (95% CI: 21.9%-26.4%) to 45.7% (95% CI: 43.3%-48.2%), and respondents reporting prenatal care in the first trimester likewise increased (37.5% to 50.1%). Among respondents who sought care for a child with fever, presenting for care within 1 day increased from 51.9% (95% CI: 47.1%-56.6%) in 2015 to 80.3% (95% CI: 74.6%-85.0%) in 2020. The estimated annual additional intervention cost was $8.84 per person., Conclusions: Our findings suggest that the ICBHSS initiative, a bundle of evidence-based interventions implemented with a community-based strategy, improves care access and quality and was associated with reduction in child mortality., Competing Interests: POTENTIAL CONFLICT OF INTEREST: The authors have indicated they have no potential conflicts of interest to disclose., (Copyright © 2021 by the American Academy of Pediatrics.)
