[Treatment of subclinical congenital toxoplasmosis by sulfadiazine and pyrimethamine continuously during 1 year: apropos of 46 cases].

UNLABELLED: In France, most of children suffering from congenital toxoplasmosis have an infraclinic or moderate type at birth. This study aimed at evaluating, on the mid term, tolerance and results of postnatal treatment previously given in severe toxoplasmosis. METHODS: A retrospective study considered 46 children with a mild or moderate congenital toxoplasmosis treated over 12 months with sulfadiazine-pyrimethamine and treatment was completed since three months. RESULTS: Five children suffered from a lesion of chorioretinitis during treatment and two after. After a mean follow-up of 27.1 months, ten children (21.7% 95%CI [12.1-35.9]) had at least one ocular injury. Specific IgG titers and immune load were diminished to become almost non-existent at the end of the year of treatment (respectively p < 10(-5) and p = 0.0005). No thrombocytopenia was observed. Twenty-three children (50%) had at least one episode of neutropenia < 1000/mm3, 14 had only one, nine presented two or more installment. None was followed by an infection. CONCLUSION: This therapeutic pathway is more demanding but shorter than those usually offered when associating pyrimethamine-sulfadiazine. Yet, it does give identical result on the mid term. Longer follow-up is needed to appreciate. Active molecule on cysts should be introduced.

[Breastfeeding and hepatitis C virus (HCV): the need for a careful appraisal].

We review the available data on the possible role of breast-feeding in hepatitis C virus (HCV) transmission to infants of HCV-RNA-positive mothers. Current knowledge about HCV excretion through breast milk, HCV infection of breast-fed infants by mothers contaminated after delivery, and vertical transmission risk to infants breast-fed by chronic HCV viremic mothers are presented. Vertical transmission risk by breast-feeding HCV-RNA-positive mothers is unclear: no study has been performed with the aim and the required methodology to evaluate HCV transmission risk related to breast-feeding duration. Recommendations to HCV-RNA-positive mothers who wish to breast-feed their infant are discussed in light of present knowledge about HCV secretion in breast milk, mother-to-infant HCV transmission, and historical records on vertical transmission of other viruses to infants breast-fed by their viremic mothers.

[Bronchopulmonary dysplasia. Course over 3 years in 88 children born between 1984 and 1988].

BACKGROUND: The survival and outcome of infants with bronchopulmonary dysplasia (BD) depend on the patient's maturity, the severity of the BD and nutritional problems. This study evaluates the specific role of chronic pulmonary failure in the growth and development of infants recovering from BD. POPULATION AND METHODS: 88 infants admitted for BD from January 1984 to December 1988, having gestational age from 25 to 41 weeks 5 days (mean: 29) and birth weight from 680 to 3,400 g (mean: 1,195) were studied. All infants were given respiratory support for 6 to 914 days (mean 84) and oxygen therapy for 28 to 1,232 days (mean: 119). 29 infants were given corticosteroids for more than 1 month. The outcome of the 80 infants with gestational ages of less than 33 weeks was compared to that of 272 infants with the same gestational age but not suffering from BD on their 28th day. The infants in both groups were examined at 2 years of age and classified as: a) handicapped (neurologic deficit, IQ < 80, hearing loss, blindness, convulsions); b) doubtful (transitory neurology dysfunction); c) normal. RESULTS: Of the 88 infants still living at the age of 28 days, 19 died before the age of 2 years: 16 of the 64 surviving infants who could be followed until the age of 2 years were classified as handicapped, 13 were considered doubtful and 35 were normal. The more significant risk factors for neurodevelopmental impairment were: a) the presence of porencephaly and/or ventricular dilatation on brain ultrasonography; b) head circumference < -2 SD at the end of hospital stay; c) oxygen therapy and hospitalization > 5-6 months. The group of infants with BD had a higher death rate (24% vs. 3.7 in the group without BD) and more frequent neurodevelopmental impairment at gestational ages of > 31-32 weeks. CONCLUSIONS: BD is an extra risk for the survival and neurodevelopment of infants with gestational age > 31 weeks.
