ABSTRACT Morbidity and mortality patterns among pregnant women and their infants (before antiretroviral therapy was widely available) determines HIV-1 diagnostic, monitoring, and care interventions.
Data from mothers and their infants enrolled in a trial of antibiotics to reduce mother-to-child-transmission of HIV-1 at 4 sub-Saharan African sites were analyzed. Women were enrolled during pregnancy and follow-up continued until the infants reached 12 months of age. We describe maternal and infant morbidity and mortality in a cohort of HIV-1-infected and HIV-1-uninfected mothers. Maternal and infant factors associated with mortality risk in the infants were assessed using Cox proportional hazard modeling.
Among 2292 HIV-1-infected mothers, 166 (7.2%) had a serious adverse event (SAE) and 42 (1.8%) died, whereas no deaths occurred among the 331 HIV-1 uninfected mothers. Four hundred twenty-four (17.8%) of 2383 infants had an SAE and 349 (16.4%) died before the end of follow-up. Infants with early HIV-1 infection (birth to 4-6 weeks) had the highest mortality. Among infants born to HIV-1-infected women, maternal morbidity and mortality (P = 0.0001), baseline CD4 count (P = 0.0002), and baseline plasma HIV-1 RNA concentration (P < 0.0001) were significant predictors of infant mortality in multivariate analyses.
The high mortality among infants with early HIV-1 infection supports access to HIV-1 diagnostics and appropriate early treatment for all infants of HIV-1-infected mothers. The significant association between stage of maternal HIV-1 infection and infant mortality supports routine CD4 counts at the time of prenatal HIV-1 testing.

    • "In one study in rural India, combinations of preterm birth and sepsis, and IUGR and sepsis, resulted in 35% and 22.5% of neonatal deaths respectively [6]. Maternal HIV infection is also associated with neonatal mortality in resource-poor settings [7]; in both HIV exposed uninfected (HEU) and HIV exposed infected (HEI) infants [8]. This may be in part due to lower specific antibody responses, associated with ante-natal HIV exposure [9]. "

    ABSTRACT: Reducing childhood mortality in resource-poor regions depends on effective interventions to decrease neonatal mortality from severe infection, which contributes up to a half of all neonatal deaths. There are key differences in resource-poor, compared to resource-rich, countries in terms of diagnosis, supportive care and treatment. In resource-poor settings, diagnosis is based on identifying clinical syndromes from international guidelines; microbiological investigations are restricted to a few research facilities. Low levels of staffing and equipment limit the provision of basic supportive care, and most facilities cannot provide respiratory support. Empiric antibiotic treatment guidelines are based on few aetiological and antimicrobial susceptibility data. Research on improving health care systems to provide effective supportive care, and implementation of simple pragmatic interventions, such as low-cost respiratory support, are essential, together with improved surveillance to monitor emerging drug resistance and treatment failures. Reductions in mortality will also be achieved through prevention of infection; including emerging vaccination and anti-sepsis strategies.

    • "The commonest major morbidity was severe febrile illness, which occurred in 34% of HIV-infected and 24% of uninfected women. These results are in line with what has been found in other sub-Saharan African countries on the impact of HIV on major maternal morbidity leading to mortality [13] [14]. A five year audit in South Africa showed that maternal mortality (meaning women experienced major morbidity) was 6-times higher among HIV-infected women than infected women [15]. "

    ABSTRACT: Objective. To compare maternal morbidity in HIV-infected and uninfected pregnant women. Methods. Major maternal morbidity (severe febrile illness, illnesses requiring hospital admissions, surgical revisions, or illnesses resulting in death) was measured prospectively in a cohort of HIV-infected and uninfected women followed from 36 weeks of pregnancy to 6 weeks after delivery. Odds ratios of major morbidity and associated factors were examined using logistic regression. Results. Major morbidity was observed in 46/129 (36%) and 104/390 (27%) of the HIV-infected and HIV-uninfected women, respectively, who remained in followup. In the multivariable analysis, major morbidity was independently associated with HIV infection, adjusted odds ratio (AOR) 1.7 (1.1 to 2.7), nulliparity (AOR 2.0 (1.3 to 3.0)), and lack of, or minimal, formal education (AOR 2.1 (1.1 to 3.8)). Conclusions. HIV was associated with a 70% increase in the odds of major maternal morbidity in these Ugandan mothers.
