Abstract: Objective The aim of this study was to compare the therapeutic efficacy of magnesium isoglycyrrhizinate and compound glycyrrhizin monoamine in treatment of patients with drug-induced liver injury (DILI). Methods A total of 102 patients with DILI were enrolled in our hospital between January 2018 and January 2020, and were randomly divided into observation and control group, with 51 cases in each group. The patients in the observation were treated by intravenous administration of magnesium isoglycyrrhizinate, those in the control were treated by intravenous compound glycyrrhizin monoamine, and the regimen lasted for 14 to 28 days. Serum laminin (LN), hyaluronidase (HA), procollagen-III (PC-III) and collage type IV (IV-Col) were detected by radioimmunoassay. Serum superoxide dismutase (SOD), nitric oxide (NO), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) were detected by ELISA. Results At the end of the treatment, serum ALT and AST levels in the observation group were (42.7±12.5)U/L and (38.2±9.4)U/L, both significantly lower than [(64.5±21.9)U/L and (55.6±15.2)U/L, respectively, P＜0.05] in the control; serum HA, PC-III and IV-Col levels were (138.2±21.5)mg/L, (85.6±17.4)μg/L and (141.5±16.4)μg/L, all significantly lower than [(182.1±23.9)mg/L, (123.8±19.4)μg/L and (175.4±18.7)μg/L, respectively, P＜0.05]; serum SOD and NO levels were (90.3±10.1)U/L and (79.8±9.3)μmol/L, both significantly higher than [(74.9±8.6)U/L and (54.0±7.9)μmol/L, respectively, P＜0.05], while serum IL-6 and TNF-α levels were (11.2±2.5)pg/mL and (26.4±3.6)ng/L, both significantly lower than [(16.8±2.7)pg/mL and (41.3±5.9) ng/L, respectively, P＜0.05] in the control. Conclusion The therapeutic efficacy of magnesum isoglycyrrhizinate is promising in dealing with patients with DILI, which could effectively improve serum biochemical indexes normal and alleviate oxidative stress.
