[Presence of antibodies against rifampicin in patients under tuberculostatic treatment].

The study was carried out in 105 patients with pulmonary tuberculosis undergoing treatment with 900 mg of rifampicin in association with 1 or 2 tuberculostatics. The drugs were given twice weekly. Between 1 and 3 investigations were performed in each patient, using the method introduced by Poole for the detection of anti-RMP antibodies.
