Summary
This study explores the feasibility of the reducing medication regimen for Ursodeoxycholic Acid(UDCA) in the treatment of primary biliary cholangitis. The participants will be distributed randomly into two experimental groups and one control group. The two experimental groups will receive reduced dosage of UDCA at different level, while the control group will receive standard dosage of UDCA. The effect of therapy will be evaluated every three months.
Description
Primary biliary cholangitis is a chronic, progressive liver disease of autoimmune origin characterized by nonpurulent destruction of intrahepatic ductule, lymphatic infiltration of portal area and long-term intrahepatic cholestasis leading to liver fibrosis and cirrhosis in absence of treatment. The diagnosis is made in the presence of antimitochondrial antibodies (AMA) coupled with an increase in alkaline phosphatase (ALP), a histologic confirmation being mandatory only in seronegative cases or overlap syndrome. Treatment is based on ursodeoxycholic acid (UDCA) and obeticholic acid, which are proved effective in improving biochemical index and preventing disease progression. While obeticholic acid is only approved in USA and Canada, UDCA seem to be the only choice for PBC patients in China. Study has shown that liver function improvement can be expected in six to nine months when patients receive standard dosage( 13 -15mg/kg/d) of UDCA. Recovery of liver function takes two years in 20% of patients ,and five years in 15% to 35% of patients. Lifetime medication is recommended among patients with good respond to UDCA, while the high cost has placed great burden on patients as well as the medical service system. Exploration of the reducing medication regimen of UDCA among stable PBC patients is of great significance under this circumstance. In our study, the 90 recruited patients of refractory PBC will be distributed randomly into two experimental groups and one control group. The two experimental groups will receive reduced dosage of UDCA at 250mg bid and 250mg qd respectively, while the control group will receive standard dosage of UDCA. The effect of therapy will be evaluated every three months, which includes assessment of symptoms, life quality, disease progression, complete blood count, urinalysis, liver biochemical markers (ALT, AST, ALP, GGT, TBIL, DBIL, TP, ALB), blood lipid (CHO, TG, LDL, HDL), immunoglobulins, ESR, AMA, liver morphology and cirrhosis degree, along with peripheral T lymphocyte subpopulations and cytokines test.
