Intensive short course chemotherapy for treatment of Greek children with tuberculosis.

This prospective study with an 18-month posttreatment follow-up evaluated the efficacy of intensive short course chemotherapy in Greek children with pulmonary or extrapulmonary tuberculosis. Between November, 1988, and March 1991 a 2-month regimen of rifampin, 10 to 12 mg/kg/day, isoniazid, 10 to 12 mg/kg/day, and pyrazinamide, 30 to 35 mg/kg/day, followed by rifampin and isoniazid for the remaining 4 months, was administered orally to 36 children with tuberculosis. Twenty-three boys and 13 girls ages 8 months to 12 years (mean, 5 1/2 years) were enrolled in the study. The diagnostic criteria for establishing tuberculosis were tuberculin skin test reactivity, radiographic findings compatible with tuberculosis, epidemiological data and clinical and laboratory findings. Four children had extrapulmonary and 32 had pulmonary tuberculosis; 9 of the latter were asymptomatic. Among the pulmonary cases there were 2 children with pleural effusion. Clinical response to therapy was apparent within 7 to 14 days; the pleural effusions resolved in 2 to 6 weeks and the pulmonary infiltrates cleared in 2 to 6 months. Hilar adenopathy regressed within 18 months or longer. No serious problems with drug tolerance or toxicity were noted during the treatment period. Temporary hyperuricemia and transient elevation in serum transaminases were observed in 11 patients but no drug modification was required. There were no posttreatment relapses. These findings suggest that intensive short course chemotherapy for the treatment of Greek children with pulmonary or extrapulmonary tuberculosis appears to be effective, safe, of good patient compliance and comparable to the longer treatment regimens.
