SO Pediatr AIDS HIV Infect. 1994 Oct;5(5):321 (unnumbered abstract). Unique Identifier : AIDSLINE AIDS/95330438 AB Thirty HIV seropositive mother-infant pairs were retrospectively studied. Maternal gestational weight gain, infant birthweight, and ultimate confirmed HIV infection status of the infants were reviewed. Mean gestational age of all infants was 39 weeks +/- 2.3, and mean birthweight 2923 g +/- 433. Seventeen percent of infants were low birthweight (LBW) (< 2500 g) and 10% were born large for gestational age (LGA) (> 3500 g). The mean birth length was 48.0 cm +/- 2.1. Of all infants seropositive at birth, 14 (47%) were ultimately documented to be infected. Maternal nutritional status as measured by prenatal weight increase or body mass index did not correlate with the development of HIV infection in the infant. Two of thirteen (15%) infected infants and 5 of 16 (31%) of noninfected infants were born prematurely. The mean birthweight of HIV-infected infants was 2942 g +/- 377 compared to 2906 g +/- 488 of HIV-noninfected infants (P = 0.82). Of the 27 infants with birth length measurements, the mean birth length of the 12 HIV-infected infants was 48.2 cm +/- 1.8 compared to that of HIV-noninfected infants 47.8 cm +/- 2.3 (p = 0.63). Two of 14 infected infants (14%) and 3/16 (19%) noninfected infants were LBW. Of the infants born to the 12 women who were also VDRL seropositive, half were ultimately determined to be HIV-infected. Infants born to women who were both VDRL and HIV seropositive had a lower birthweight than infants of women who were VDRL seronegative and HIV seropositive (p = 0.017). We conclude that 1) the prevalence of vertical transmission of HIV to the newborn is high in Northern Thailand, 2) there is no association between maternal nutritional status and vertical transmission, and 3) unlike infants born to VDRL seropositive mothers, infants vertically infected with HIV were no more likely to be SGA than non-infected infants. We conclude that neonatal HIV infection is not necessarily associated with low birthweight and that a substantial number of infants with vertical infection become infected at or after birth in our population.
