[The current situation and treatment of childhood tuberculosis].
We performed a retrospective analysis of 394 patients who were treated for active tuberculosis (TB) at our hospital from 1976 to 1997. The diagnosis criteria for establishing TB were history of direct contact with TB patients, tuberculin skin test reactivity, positive bacteriology and radiographic findings compatible with TB. There were 192 males and 202 females (age range 1 month to 18 years of age, mean 6.3 years of age). Fifty-four percent of the cases were under 5 years of age. Primary pulmonary TB was presented in 200, post primary pulmonary TB in 97, pleural effusion in 53, endbronchial TB in 4, TB meningitis (TBM) in 28, miliary TB in 28 and other extra-pulmonary TB in 31. A history of contact with the patients was obtained in 72.8% of cases. Two hundred and thirty (58.4%) had received BCG, 134 (34%) no BCG, 30 (7.6%) were unclear. Especially, under 5 years of age, only 29 (13.6%) had received BCG. TBM is not disappeared in Japan and there were 28 cases with TBM. Fifteen patients out of them recovered completely, 8 patients recovered with severe neurological sequelae which included mental retardation, motor weakness, seizures and hydrocephalus and 5 patients died. Twenty-six had no BCG. Particularly in 1990s, we had experienced 4 dead TBM cases, 1 multi-drug resistant (MDR) TBM case and 1 TBM case due to nosocomial infection. Children with TBM should received 12-month regimen using initial daily treatment with isoniazid, rifampin, pyrazinamide, and streptmycin, followed by isoniazid and rifampin administered daily. Pulmonary TB in children is successfully treated with 6-month standard chemotherapy using isoniazid, rifampin, and pyrazinamide daily for 2 months, followed by isoniazid and rifampin daily for 4 months. In order to promote TB control and eliminate childhood TB, especially in infants, the following is necessary; 1) early detection and treatment of adult TB patients, source of infection, 2) prompt and appropriate contact examination and chemoprophylaxis, 3) BCG vaccination during early infancy, 4) protection from MDR TB are most important in Japan.
