Abstract: Objective The aim of this study was to explore the clinical efficacy of obeticholic acid (OCA) and fibrates rescue therapy in patients with primary biliary cholangitis (PBC) who didn’t response to ursodeoxycholic acid (UDCA) treatment. Methods 41 PBC patients without complete response to UDCA therapy were encountered in our hospital between January 2019 and December 2020, and were randomly divided into control (n=20) and observation group (n=21), receiving OCA or OCA and fenofibrate combination at base of UDCA maintaining treatment in both group for 24 weeks. Serum type IV collagen (IV-C), hyaluronic acid (HA), type III procollagen (PIIIP) and laminin (LN) were detected by radioimmunoassay, serum immunoglobulins (IgG, IgA and IgM) were detected by immunoturbidimetry, and serum interleukin-2 (IL-2), IL-6, IL-10 and tumor necrosis factor-α (TNF-α) were detected by ELISA. Results At the end of 24 week treatment, serum ALT, bilirubin, GGT and ALP levels in the observation group were (29.1±5.3)U/L, (24.8±4.1)μmol/L, (86.4±15.7)U/L and (100.6±26.3)U/L, all significantly lower than [(42.8±7.6)U/L, (30.2±6.5)μmol/L, (121.7±18.6)U/L and (131.8±33.7)U/L, respectively, P<0.05] in the control; serum IV-C, HA and P Ⅲ P levels were (125.1±19.5)μg/L, (118.5±28.9)μg/L and (136.8±31.5)μg/L, all significantly lower than [(149.3±30.1)μg/L, (165.3±40.2)μg/L and (167.9±42.8)μg/L, respectively, P<0.05] in the control; serum IgG, IgA and IgM levels were (11.7±1.6)g/L, (2.9±0.5)g/L and (2.2±0.3)g/L, all significantly lower than [(15.9±2.2)g/L, (3.6±0.7)g/L and (3.0±0.8)g/L, respectively, P<0.05] in the control group; serum IL-2 level was (84.6±18.4)pg/ml, significantly higher than [(63.2±12.9)pg/ml, P<0.05], while serum IL-6 and TNF-α levels were (3.3±1.4)pg/ml and (5.1±1.9)pg/ml, both significantly lower than [(6.6±1.8)pg/ml and (7.4±2.3)pg/ml, P<0.05] in the control. Conclusion The rescue treatment of OCA and fibrate combination in dealing with PBC patients without complete response to UDCA therapy could improve liver function tests and alleviate liver fibrosis, which might be related to inhibition of immunoglobulins secretion and regulation of serum cytokine metabolism.
