Abstract:

SETTING: Department of Pediatrics, Istanbul University Faculty of Medicine, Istanbul, Turkey, between January 1984 and December 1996.

OBJECTIVE: To explore whether neonatal BCG vaccination offers any protective effect on clinical and laboratory profiles of central nervous system (CNS) tuberculosis in children.

DESIGN: A retrospective review of cases of CNS tuberculosis diagnosed and treated in one institution.

RESULTS: Of the 145 patients identified with CNS tuberculosis, 9.6% were vaccinated during the neonatal period. The rate of close contact with contagious pulmonary tuberculosis in family, age distribution, clinical findings and laboratory investigations on admission were not significantly different in vaccinated and non-vaccinated children. Although mortality rate in the vaccinated patients (8.3%) was found to be nearly half of that in the non-vaccinated group (15.1%), severe sequelae were significantly more frequent (P < 0.02) among the vaccinated patients.

CONCLUSION: This study shows that neonatal BCG vaccine has little effect on the clinical findings of subsequent CNS tuberculosis, and that these children have typical presentations of tuberculosis disease.
