Objective: To evaluate the efficacy and safety of Chinese medicine (CM) intervention in the treatment of nonalcoholic steatohepatitis (NASH) from liver enzyme (ALT), imaging (the liver/spleen CT ratio) and syndrome scores, and to establish standard methods for diagnosis and therapeutic efficacy evaluation with characteristics of CM.
Methods: A multi-center, stratified randomized, parallel controlled, blindness-method evaluated, superiority trial was performed. Totally 204 patients were randomly allocated into two groups, 102 patients in the experimental group (treated with CM) and 102 patients in the control group [treated with Western medicine (WM)]. The alanine aminotransferase (ALT), liver/spleen CT ratio, and clinical symptoms were observed in both groups.
Results: Of the randomly allocated 204 cases from 4 hospitals, 3 patients were rejected, and 25 were lost. Totally 176 cases con- formed to the plan with complete follow-ups. After 3 months of treatment, syndrome scores and the improvement of partial clinical symptoms (fatigue and sallow complexion) were superior in the experimental group to those in the control group (P < 0.05). After 3 months of follow-up, the syndrome scores and improvement of partial clinical symptoms (fatigue and sallow complexion) were superior in the experimental group to those in the control group (P < 0.05). There was no statistical difference in improving liver enzymes or the liver/spleen CT ratio between the two groups (P > 0.05). There were 4 adverse reactions/adverse events in the two groups in the process of treatment, mainly covering drug-induced liver injury, diarrhea, and epigastric distension. Adverse reactions had nothing to do with CM treatment.
Conclusions: Jianpi Shugan Recipe had obvious efficacy in treatment of NASH. It could remove the liver fat and play a role in anti-inflammation and liver protection. It also could improve the indices of liver enzymes and the liver/spleen CT ratio effectively, which was superior to Polyene Phosphatidylcholine Capsule (PPC) in improving clinical symptoms, especially for such symptoms as fatigue and sallow complexion.
