OBJECTIVES: Currently, there are no effective therapeutic agents for patients with primary sclerosing cholangitis (PSC). This study aimed to evaluate the safety and efficiency of immunosuppressive agents (IAs) for the treatment of PSC. METHODS: The literatures were searched using the following keywords singly or in combination: PSC, treatments, IAs. The primary outcome was defined as the need for liver transplantation or mortality. RESULTS: Two hundred sixty six patients from 7 eligible studies were analyzed. IAs had no remarkable effects on the rate of mortality or liver transplantation (relative risk, RR 1.02, 95% CI 0.58-1.62, p = 0.92). Subgroup analyses showed no significant effect of IAs co-administration therapy (IAs co-administered with ursodeoxycholic acid, IA co-administered with IA; RR 1.41, 95% CI 0.40-4.95, p = 0.60). IAs caused adverse events (AEs) such as diarrhea, abdominal pain, and pruritus (RR 1.81, 95% CI 1.07-3.07, p = 0.03). IAs therapy did not significantly improve markers of liver function except for aspartate transaminase (weighted mean difference -9.76, 95% CI -12.92 to -6.6, p < 0.001). CONCLUSION: IAs administrated as either monotherapy or combination therapy do not reduce the risk of mortality or liver transplantation. IAs monotherapy is associated with AEs.
