BACKGROUND: Effective treatment for primary biliary cirrhosis (PBC) resulting in slower progression and improved survival remains elusive. Cyclosporin A (CyA), which has been so effective in preventing human allograft rejection, has shown promise in small numbers of patients in early studies.
METHODS: Three hundred forty-nine patients with PBC were randomized to receive CyA, 3 mg.kg-1.day-1, or placebo in a multicenter study with follow-up for 6 years. The end point was death or liver transplantation.
RESULTS: Cox multivariate analysis showed time from entry to death or transplantation was significantly prolonged (by up to 50%) in the CyA-treated group. Liver-related mortality was also significantly lower. However, a univariate analysis of survival showed no statistical differences between the two groups. Biochemical liver indices deteriorated more slowly in the CyA-treated group, but serum creatinine concentration was elevated > 150 mumol/L in 9%, necessitating permanent discontinuation in half of these. A reduction in the dose of CyA was required in 11% because of hypertension.
CONCLUSIONS: CyA has some therapeutic potential in primary biliary cirrhosis, providing blood pressure and renal function are closely monitored.
