Protective Effects of Caffeic Acid Phenethyl Ester on Isoniazid and Rifampicin-induced Hepatic and Pancreatic Injury



Objective: To investigate the protective effects of caffeic acid phenethyl ester (CAPE) against isoniazid (INH)- and rifampicin (RFP)-induced hepatic and pancreatic damage.

Methods: Eighty adult rats were randomly divided into eight groups: control, INH, RFP, INH+RFP, INH+CAPE, RFP+CAPE, INH+RFP+CAPE, and CAPE. Both INH and RFP were orally administered for 30 days at a dose of 50 mg/kg/day. Caffeic acid phenethyl ester was intraperitoneally injected for 30 days (10 μmol/kg). Blood samples, hepatic and pancreatic tissues were obtained on day 30.

Results: Total oxidant status levels were significantly higher in INH and/or RFP-treated groups than those of control and CAPE groups, while total antioxidant status and paraoxonase levels were significantly reduced in INH-RFP groups compared with the group receiving CAPE. Histopathological deterioration was observed in RFP and INH groups in pancreatic and hepatic tissue. However, significant amelioration was observed in CAPE-treated groups.

Conclusion: Our findings suggest that CAPE may be a promising agent to prevent the side effects of INH and RFP treatment on hepatic and pancreatic tissues.
