Short course intermittent chemotherapy in childhood tuberculosis.

A total of 130 children diagnosed as having pulmonary and extrapulmonary tuberculosis who received short course intermittent chemotherapy between 1978-1992 were evaluated retrospectively. One hundred and ten children with tuberculosis were treated with isoniazid (10-15 mg/kg, maximum 400 mg), rifampin (10-15 mg/kg, maximum 600 mg), and streptomycin (30 mg/kg, maximum 1 g) daily, for 15 days. Treatment was completed with similar doses of isoniazid and rifampin twice a week for a period of 9 months. Since 1986, 20 children with tuberculosis were being treated with the same regimen but without streptomycin. The majority of patients in these cases had pulmonary tuberculosis (75%), followed by lymph nodes (9%), pleural (7%), bone and joint (5%), miliary (3%), and abdominal tuberculosis (1%). The clinicoradiologic response to treatment was observed to be excellent. Only one case of relapse was detected, which was the case of a patient with lymph node tuberculosis that occurred 18 months after the completion of treatment. No serious adverse drug reaction was observed in any of the cases mentioned. In conclusion, short-course low-dose intermittent chemotherapy is an effective and economical treatment with minimal side effects for pulmonary and extrapulmonary tuberculosis in childhood.
