36 Weeks Short-Term Optimization Treatment of Glucocorticosteroid in the Patients With Chronic Recurrent DILI

Overview

This study is to observe the efficacy and safety of 36 weeks short-term optimization treatment of glucocorticosteroid in the patients with chronic recurrent drug-induced liver injury (DILI).

Drug-induced liver injury (DILI) refers to liver diseases caused by drugs and toxic substances. DILI is a clinical event that can be associated with severe outcomes such as acute liver failure. Up to now, approximately 1100 drugs, herbal products, vitamins and illicit compounds are associated with liver injury. Recently, the incidence of DILI is rising. In our hospital, hospitalized patients with DILI was increased from 1.39% in 2002 to 2.31% in 2006, and further up to 3.17% in 2011, which indicated 2.3-folds increase over last ten years. About 20% patients with acute DILI are prone to chronic liver disease. For patients with chronic recurrent DILI, routine liver protective treatment was difficult to rescue abnormal liver functions. Moreover, increasing health care costs seriously affect the patient's quality of life. Glucocorticosteroids can inhibit the non-specific inflammation and permeability of the capillary bile duct, limit the activation of T lymphocytes, and selectively inhibit B lymphocytes to produce antibodies, thus preventing or delaying the immune-induced liver injury. In our pre-clinical trials (NCT02651350), we found that the rate of recurrence of the glucocorticoid treatment group was significant lower (\<10%) than the control group (about 50%) (P \<0.001) and there was significant difference of liver histological change during baseline and treatment end between the glucocorticoid treatment group and the control group. Meanwhile, we did not find obvious glucocorticoid's side effect in the glucocorticoid treatment group. At the same time, we found that there was good effect in 36 weeks glucocorticoid treatment in several patients. Therefore, we shall design two groups on the basis of the ratio of 1:1, namely, 36 weeks of glucocorticoid treatment group and 48 weeks of glucocorticoid treatment group in order to evaluate the efficacy and safety of 36 weeks short-term optimization treatment of glucocorticosteroid in the patients with chronic recurrent DILI. Participants in 36 weeks of glucocorticoid treatment group will receive methylprednisolone, 48mg/d for the 1st week, 32mg/d for the 2nd week, 24mg/d for the next two weeks, followed by 16mg/d for 20 weeks and reduction in doses of methylprednisolone by 4 mg per 4 weeks until drug withdrawal. Participants in 36 weeks of glucocorticoid treatment group also will receive standard treatment including reduced glutathione, glycyrrhizin, ademetionine, alprostadil, or ursodeoxycholic acid (UDCA).Participants will then be followed for 24 weeks. Participants in 48 weeks of glucocorticoid treatment group will receive methylprednisolone, 48mg/d for the 1st week, 32mg/d for the 2nd week, 24mg/d for the next two weeks, followed by 16mg/d for 32 weeks and reduction in doses of methylprednisolone by 4 mg per 4 weeks until drug withdrawal. Participants in glucocorticoid 48 weeks of treatment group also will receive standard treatment including reduced glutathione, glycyrrhizin, ademetionine, alprostadil,or ursodeoxycholic acid (UDCA).Participants will then be followed for 24 weeks. The efficacy and safety of 36 weeks short-term optimization treatment of glucocorticosteroid in the patients with chronic recurrent DILI will be observed and compared with 48 weeks glucocorticosteroid treatment during the treatment and follow-up period.
