AbstractThis is a retrospective study of congenital tuberculosis in Queen Sirikit National Institute of Child Health from 1979 to 1998. There were 9 patients with a mean birth weight of 2,500 grams (range 1,800-3,300). The onset of symptoms and age of diagnosis ranged from 7 to 42 (mean, 21) days and 14 to 75 (mean, 54) days after birth, respectively. The presenting signs and symptoms were fever (100%), poor feeding (1 00% ), irritability ( 100% ), failure to gain weight ( 100% ), hepatomegaly (1 00% ), spleno megaly (77.8%), cough (88.9%), respiratory distress (66.7%) and abdominal distension (77.8%). The tuberculin skin test reaction with ;:::: 10 mm induration was found in 2 of 8 patients. Their abnormal chest radiographs revealed bronchopneumonia 66.7 per cent, miliary pattern 33.3 per cent and multiple cystic lesion 11.1 per cent. The bacteriological study from gastric aspirate content for acid-fast bacilli (AFB) staining and culture were positive in 62.5 and 71.4 per cent respectively. Fatality rate was 33.3 per cent with no sequele found in the survivors. Congenital tuberculosis is a rare entity and difficult to give an early diagnosis. There should be a high index of suspicion for tuberculosis in those who had pneumonia and were unresponsive to aggressive antibiotics or had unexplained etiology.
