[The treatment of primary biliary liver cirrhosis with rifampicin].
Seven patients with primary biliary cirrhosis were treated with rifampicin administered for 2 weeks in a daily dose 450-600 mg. Due to the treatment the itch disappeared completely in 4 and decreased significantly in 3 patients. As shown by the antipyrine test, half-life and clearance of antipyrine returned to normal suggesting cytochrome P-450 induction as a result of hydroxylation activity. There was a tendency to lowering of bilirubin, cholesterol, alkaline phosphatase, asparagine--and alanine aminotransferase against an increase in gammaglobulins. The differences were, however, insignificant. Rifampicin tolerance was satisfactory.
