Abstract

Background: Non-alcoholic steatohepatitis (NASH) is a clinical condition with a global prevalence of 25.24%. Peroxisome proliferator-activated receptors (PPAR) have been significantly associated with the pathogenesis of NASH.Aim: To evaluate the efficacy of saroglitazar in an animal model of NASH by evaluating the magnitude of changes in liver function tests (LFT) and histopathology.Materials and Methods: The baseline parameters of 14 male Sprague–Dawley rats were recorded and then grouped into four groups: treatment groups (high high-dose saroglitazar [HDSG] and low low-dose saroglitazar [LDSG] doses of saroglitazar), normal control, and disease control. Initially, except for the normal control, the other three groups were fed a fructose diet for 5 weeks and then all four groups were fed a standard chow diet for the next 2 weeks during which the two treatment groups were orally gavaged with saroglitazar. Changes in LFT, body weight (BW), lipid profile, oxidative stress, and histopathology were evaluated at different time points.Results: A statistically significant reduction was found in the mean serum glutamic-oxaloacetic transaminase (SGOT) (p = 0.0267) and serum glutamate-pyruvate transaminase (SGPT) (p = 0.0059) between the groups at the end of treatment. As with BW changes (p < 0.001), a significant difference was observed between the time points in HDSG and LDSG with respect to all parameters of the lipid profile assessed (p < 0.05). Amelioration of hepatocellular ballooning and lobular inflammation in histopathology was evident in both treatment groups. Immunohistochemistry revealed loss of cytokeratin CK8/18 in disease control while it was preserved in LDSG and HDSG.Conclusion: The study has explicitly illustrated the improvement in the biochemical and pathological changes in the rat model of NASH induced by a high fructose diet.
