Connatal Tuberculosis in a Very Premature Infant

Connatal tuberculosis is increasing in incidence and the mortality and morbidity of this disease remains high. We report a 27-week-old, 896 g female premature infant who had mild respiratory distress syndrome after birth. She developed signs of infection, progressive pneumonia and atelectasis which did not respond to mechanical ventilation and antibiotics. At 41 days of age, Mycobacterium tuberculosis was isolated from the non-bronchoscopic bronchoalveolar lavage. The isolate was sensitive to isoniazid, rifampin, streptomycin, and pyrazinamide . Miliary tuberculosis was subsequently diagnosed in her mother on a chest X-ray film and sputum cultures. The infant was treated successfully with anti- tuberculosis drugs. She had normal growth and development at the chronological age of 20 months old. Conclusion:Connatal tuberculosis should be considered in premature infants with symptoms of sepsis refractory to antibiotics. Most premature infants with connatal tuberculosis have lung involvement, and non- bronchoscopic bronchoalveolar lavage can be a useful procedure to establish the diagnosis
