CONTEXT Altered immune responses might contribute to the high morbidity and mortality observed in human immunodeficiency virus (HIV)-exposed uninfected infants. OBJECTIVE To study the association of maternal HIV infection with maternal- and infant-specific antibody levels to Haemophilus influenzae type b (Hib), pneumococcus, Bordetella pertussis antigens,(More)
HIV-exposed uninfected (HEU) infants have higher infectious morbidity than HIV-unexposed uninfected (HUU) infants. We present the clinical outcomes from a pilot cohort study of 27 HEU and 28 HUU infants. In the absence of infant malnutrition or advanced maternal HIV, HEU infants experienced a 2.74 (0.85-8.78) times greater risk of hospitalization in the(More)
The first year of life represents a time of marked susceptibility to infections; this is particularly true for regions in sub-Saharan Africa. As innate immunity directs the adaptive immune response, the observed increased risk for infection as well as a suboptimal response to vaccination in early life may be due to less effective innate immune function. In(More)
HIV-exposed but uninfected (HEU) infants born to HIV-infected mothers from areas in the world with a high burden of infectious disease suffer higher infectious morbidity and mortality than their HIV unexposed uninfected (HUU) peers. Vaccination provides protection from infection. The possibility exists that altered response to vaccination contributes to the(More)
BACKGROUND Early in life, HIV-exposed uninfected (HEU) infants are at an increased risk of morbidity and mortality from infectious disease compared with HIV-unexposed (UE) infants. To improve our understanding of the mechanisms underlying their increased risk, we contrasted innate immune development between HEU and UE infants in a developing world setting,(More)
