Therapeutic effect of ursodeoxycholic acid on early-stage primary biliary cirrhosis.
Primary biliary cirrhosis is a rare chronic liver disease in Taiwan, which eventually causes mortality. As yet, no safe and effective treatment has been found. To investigate the safety and therapeutic efficacy of recently introduced ursodeoxycholic acid (UDCA) in the treatment of primary biliary cirrhosis, an uncontrolled trial was conducted in 6 patients in the early stages (I-II) and 5 patients in the late stages (III-IV). Five patients in stage I and one patient in stage II were treated with 10-15 mg/kg/day UDCA for a mean administration period of 13 +/- 9 months. Levels of laboratory tests including serum alkaline phosphatase (ALP), alanine aminotransferase (ALT) and aspartate aminotransferase (AST) improved significantly within one month and were sustained at the new lower levels for the period of observation. The symptoms of one patient with pruritus were reduced after long-term therapy. No major side effects were found during the treatment period. In contrast to early-stage patients, patients with late-stage primary biliary cirrhosis who received UDCA therapy for a mean duration of 25 +/- 5 months showed no beneficial effects either clinically or biochemically. From these preliminary results, UDCA appears to be safe and effective in the treatment of early-stage primary biliary cirrhosis, although further controlled clinical trials in conjunction with histological follow-up are mandatory to evaluate the critical role of UDCA in primary biliary cirrhosis.
