Background: Infants are protected from measles infection by maternal measles antibodies (MMA). The level of these MMA at birth in newborn children depends on the levels in their mother and the extent of placental transfer. We investigated maternal HIV infection as a predictor of levels of MMA in mother-infant pairs in Maiduguri.
Methods: A total of 180 mother-infant pairs were tested for MMA between 15th January and 29th March 2010. Levels of MMA were measured using enzyme linked immunosorbent assay (ELISA) test.
Results: Fifteen (8.3%) mothers were found with HIV infection and all were on antiretroviral treatment for HIV, and all of them had protective MMA. Of these mothers with HIV infection, only one (0.6%) of their newborn infants had un-protective level of maternal measles antibody. Maternal measles antibodies in mother-infant pairs had significant correlation (p = 0.005) for both HIV-infected and HIV-uninfected groups. The mean MMA of the newborn children was lower in infants of HIV-infected mothers than in HIV-uninfected mothers (p = 0.37). Linear regression analysis showed no significant association between maternal HIV infection and MMA in mother-infant pairs (p = 0.72) for mothers and (p = 0.37) for newborn infants.
Conclusion: Maternal HIV infection was not associated with significantly reduced MMA in mother-infant pairs, as high protective levels were evident in both mother-infant pairs at birth.

This study investigates the association between prenatal exposure to dioxin-like polychlorinated biphenyls (DL-PCBs) and glucocorticoid and androgenic hormone levels in cord blood. We analyzed cord blood samples from 500 mother-infant pairs from China (2022-2023), focusing on hormones including cortisol, cortisone, dehydroepiandrosterone (DHEA), and androstenedione. The main analysis revealed significant reductions in cortisol levels with increased exposure to PCB-77 (β = -3.

Gestational diabetes mellitus (GDM) is known to be associated with dysbiosis of offspring gut microbiota, but the mechanism remains unclear. The present prospective study explored the role of human milk fatty acid composition in this association. Mothers with GDM and normal controls were recruited at 24-28 gestational weeks.

Background: Historically, children who are HIV-exposed, uninfected (CHEU) have been found to have greater morbidity and mortality than children who are HIV-unexposed, uninfected (CHUU). To assess whether this difference persists in the era of universal antiretroviral therapy (ART), we conducted a cohort study to compare the risk of acute diarrhoea, respiratory tract infections (RTI), malaria, hospitalisation, and all-cause mortality between Kenyan CHEU and CHUU from birth to 2 years.
Methods: From December 2018 to March 2020 at Mathare North Health Centre in Nairobi, we recruited pregnant women living with HIV on ART for ≥6 months and pregnant women without HIV from the same community.

Introduction: Effective prevention of mother to child transmission (PMTCT) programmes require women and their infants to have access to a cascade of HIV care and treatment interventions. Retention in care reduces the risk of vertical transmission and opportunistic infections among mothers living with HIV. Uganda has made great strides in ensuring the success of the prevention of mother to child transmission program.

Background: Zika virus (ZIKV) infection during pregnancy can lead to congenital Zika syndrome (CZS) and may result in neurodevelopmental alterations in exposed children, with and without CZS. This study aimed to evaluate ZIKV infection during pregnancy as a risk factor for early and long-term adverse outcomes.
Methods: This retrospective-prospective, matched cohort study was conducted in Mato Grosso do Sul, Brazil.
