Results are presented of the incidence of hepatitis, nearly always with jaundice, among 1686 patients in clinical trials of the treatment of spinal tuberculosis, of tuberculosis meningitis and of pulmonary tuberculosis with short-course regimens containing rifampicin, isoniazid, streptomycin and pyrazinamide. The incidence was high in patients treated with(More)
The serum concentrations of some acute phase proteins were determined on admission, during treatment, at the end of treatment and at 12 months after stopping treatment in 20 patients with pulmonary tuberculosis. Measurements were also made, on admission and at the end of treatment, in 19 patients with abdominal tuberculosis, and 11 children with tuberculous(More)
OBJECTIVE To evaluate the efficacy of split-drug regimens for treatment of patients with sputum smear-positive pulmonary tuberculosis in south India. DESIGN Randomized controlled clinical trial where eligible patients were randomly allocated to: (i) 2RE(3)HZ(3)(alt)/4RH(2) (split I): rifampicin plus ethambutol given on one day and isoniazid plus(More)
The effect of daily administration of rifampin on the direct conversion of isoniazid to isonicotinic acid and hydrazine by isoniazid hydrolase was investigated in 6 slow and 8 rapid acetylators of isoniazid. The proportion of isoniazid metabolized through this direct pathway during the first 6 h was estimated from the ratio of total isonicotinic acid formed(More)
The results are presented of a retrospective analysis of the incidence of jaundice among 3,000 patients with pulmonary tuberculosis and of the activities of serum aspartate aminotransferase among 850 according to their isoniazid acetylator phenotype. The patients had been treated with a variety of isoniazid-containing regimens in a series of controlled(More)
Adrenocortical function was studied in patients with pulmonary tuberculosis and the findings compared with those in healthy subjects. Plasma cortisol levels in newly diagnosed patients were appreciably higher than in the healthy subjects (P less than 0.001). A normal (positive) response to ACTH (tetracosactrin) stimulation was observed in 35 (97%) of 36(More)
To gain a better understanding of the role of iron in the pathogenesis of tuberculosis, the growth and production of siderophores were studied in the presence of different concentrations of free iron in vitro with M. smegmatis and virulent, avirulent and low virulent strains of M. tuberculosis. Increase in the concentrations of iron caused an appreciable(More)
Ivermectin treatment was evaluated for efficacy and side effects in 40 patients in South India who had microfilaremia and bancroftian filariasis. Ivermectin was administered once orally at four dose levels (range, 25 to 200 micrograms/kg), and at each it was found to be completely effective in clearing blood microfilariae within five to 12 days. In most(More)
