[Congenital tuberculosis: difficulties in early diagnosis].
BACKGROUND
Neonatal and/or congenital tuberculosis is insufficiently understood.


METHODS
Case 1. A premature hypotrophic neonate presented at the age of 45 days, without any maternal contact, a bilateral bronchopneumopathy. Whilst the pregnancy and birth had not been affected by any noteworthy problem, the mother died from miliary tuberculosis despite rifampin, isoniazid and pyrazinamide treatment. Her baby also died on day 52 from multivisceral failure. Culture of tracheal secretions confirmed a few weeks later the diagnosis of tuberculosis. Case 2. A premature, hypotrophic neonate presented on day 22 signs of respiratory distress (miliary), icterus and hepatosplenomegaly. Whilst the pregnancy and birth had not been affected by any particular problem, the mother, 18 days after giving birth, presented miliary and pleural tuberculosis. Despite treatment with rifampin, isoniazid and pyrazinamid started on day 22, the baby died on day 27 from multivisceral failure. The post-mortem liver biopsy confirmed the diagnosis of tuberculosis. Case 3. A baby born at term was hospitalized on day 4 for jaundice. Whilst the pregnancy and birth had not presented any problem, the mother developed a pleural tuberculosis on day 10. Breast-feeding was stopped. Due to the presence of opacities at the top of the right lung, the child was given rifampin, isioniazid, and pyrazinamide. The course was marked by the appearance of hepatomegaly and poor weight gain up to day 25, followed by an improvement.


CONCLUSIONS
The frequency of congenital tuberculosis is probably under-estimated. Its early diagnosis is essential but often difficult as the initial manifestations are delayed. Improved screening of women at risk and sensitization of the medical community are necessary.
