RESUMEN
OBJECTIVE: The aim of this study was to determine by a prospective study: the presence of anti-hepatitis E virus (HEV) and or HEV RNA in the colostrum of HEV infected mothers; transmission of HEV to infants from their mothers by breast-feeding. METHOD: Ninety-three infected pregnant mothers in the third trimester of pregnancy of which 36 were positive for anti-HEV antibodies and 57 for HEV RNA (index patients) and 90 healthy pregnant mothers (control subjects) were studied. Maternal blood was taken at 7th and 9th of gestation and also within 5 days post-partum, along with colostrum and tested for anti-HEV and HEV RNA. Blood samples were collected from all infants at birth (cord blood) and at 1, 3, and 6 and 9 months of age. RESULTS: There were 12 cesarean sections and eighty full term vaginal deliveries. Anti-HEV antibody and HEV-RNA was present in the colostral samples but in significantly lower levels ( p<0.001) as compared to corresponding maternal levels. Within 2 weeks post-partum, 6 of these 93 index patients, whose infants were anti-HEV antibody and HEV RNA negative at birth, developed acute hepatic disease. These mothers, four of whom delivered by cesarean section, had anti-HEV titers ranging from 1:10,000 to 1:60,000 and HEV RNA ranging from 1.5x10(6) to 2.5x10(4) copies/ml. Due to acute maternal disease their six respective infants were formula fed. Four of these infants were in close maternal contact, frequently kissed and cuddled, and developed symptomatic liver disease by 6-8 weeks of age. Apart from these 6 infants the remaining were exclusively breast-fed for 3.6+/-0.32 months. There was no evidence of HEV infection in the remaining babies. All mother-infant pairs from the control group remained anti-HEV negative throughout this study. CONCLUSION: Although anti-HEV antibody and HEV-RNA are present in the colostrum of HEV infected mothers, breast-feeding appears to be safe for these infants. However this report must be confirmed by others. Transmission of infection may occur postpartum, through close contact of mother-infant pairs, especially in the presence of acute maternal disease.

OBJECTIVE: To compare the effects of labor induction with those of cesarean delivery without labor on neonatal outcome in pregnancies complicated by severe preeclampsia and delivery of very-low-birth-weight infants. STUDY DESIGN: This retrospective study covered 400 singleton, live-born infants who weighed 750-1,500 g at birth and were delivered because of severe preeclampsia. Outcome in infants delivered by cesarean section without labor was compared with that in infants exposed to labor induction. RESULTS: Of the 400 women with severe preeclampsia who delivered infants between 750 and 1,500 g; 280 (70%) had labor induced, and 120 (30%) delivered without labor. Vaginal delivery was accomplished by 182 (65%) women in the induced group. Apgar scores of < or = 3 at five minutes was more common in the labor-induced group (6% versus 3%, P = .04); however, other neonatal outcomes, including respiratory distress syndrome, ventricular hemorrhage, sepsis, seizures and neonatal death, were similar in the two groups. Data analysis of the induced group did not reveal an association between route of delivery and neonatal outcome. Outcome in both groups was satisfactory at six months. CONCLUSION: Induction of labor in women with severe preeclampsia is not harmful to very-low-birth-weight infants and appears to be a safe mode of delivery.

OBJECTIVE: To determine the course and outcome of pregnancy in 54 persistently HIV-1-seronegative pregnant commercial sex workers (prostitutes). STUDY DESIGN: Five hundred twenty-three initially HIV-1-seronegative prostitutes in Manipur, India, were studied between 1990 and 1999. Two hundred forty (46%) women seroconverted to HIV-1 during the study period. HIV-1 polymerase chain reaction with env, nef and vif gene primers was done on 98 persistently seronegative sex workers, who remained seronegative after three years of follow-up. Fifty-four of these women became pregnant (study group). The course and outcome of pregnancy were studied prospectively in 54 persistently HIV-1-seronegative women and compared with those in matched HIV-1-seronegative women from the general population coming for routine antenatal checkups. RESULTS: In the 54 seronegative women (study group) who became pregnant, there were 52 singleton, term vaginal deliveries and two emergency cesarean sections for fetal distress. All 54 infants had negative viral cultures for HIV-1 at birth. The women remained seronegative throughout pregnancy, as did the control group. All 54 infants were breast-fed and remained well. CONCLUSION: A small proportion of highly exposed individuals may have natural protective immunity to HIV, may be resistant to HIV-1 and may have successful outcomes of pregnancy.
