July 20, 2019 updated by: Yao Xie, Beijing Ditan Hospital

Clinical Observation of Long-term Efficacy and Safety of Glycyrrhizic Acid Preparation in the Treatment of Autoimmune Liver Disease

This study was a retrospective clinical observation cohort study. All patients with autoimmune liver disease treated with glycyrrhizic acid preparations in the Department of Liver Diseases, Department of Liver Diseases, Beijing Ditan Hospital, Capital Medical University, were enrolled. Clinical follow-up data including demographics, hematuria, and liver and kidney were collected. Functional, electrolyte blood glucose, PTA, erythrocyte sedimentation rate, serum AFP and other clinical biochemical indicators and autoantibodies, special proteins and liver imaging (liver ultrasound) examination. The clinical effect of glycyrrhizic acid preparation for the treatment of autoimmune liver disease for 144 weeks and the safety during treatment were analyzed.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
The ratio of sustained biochemical responses
Time Frame: at 96 weeks and 144 weeks after treatment
The ratio of sustained biochemical responses at 96 weeks and 144 weeks after treatment with glycyrrhizic acid preparation in patients with autoimmune liver disease
at 96 weeks and 144 weeks after treatment

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
The incidence of decompensated liver cirrhosis and liver cancer and its complications
Time Frame: at 96 and 144 weeks after treatment
The incidence of decompensated liver cirrhosis and liver cancer and its complications at 96 and 144 weeks after treatment with glycyrrhizic acid in patients with autoimmune liver disease
