Re-evaluation of liver injury associated with Buguzhi Preparations based on passive monitoring data and hospital cases / 中国中药杂志

ABSTRACT

In this paper,the case reports on rug-induced liver injury( ADR cases) related to Gukang Capsules containing Psoralea corylifolia( Buguzhi,BGZ) were collected from the adverse reaction monitoring database from January 1,2012 to December 31,2016,and the in-patients cases with drug-induced liver injury admitted to a tertiary Class A liver disease hospital from January 1,2010 to December 31,2016 were also collected. These collected cases were re-evaluated and analyzed. 110 cases with liver injury related to this preparation were collected from adverse reaction monitoring database,and 55 cases of them received the preparation alone,mainly for fracture treatment( 52. 74%). Ninty one cases( 82. 72%) met the standard of the biochemical diagnostic criteria for drug-induced liver injury. 89. 01% of patients were over the age of 41 and women accounted for 60. 9%. The time from administration to liver injury was 1-208 days,with the median of 29 d. The dose of the preparation was 2. 4-4. 8 g per day,with a cumulative dose ranging from 3. 6-699. 6 g. The recovery and improvement rate reached 96. 70% after positive treatment. Seven inpatient cases related to the preparation were collected in a tertiary Class A liver disease hospital,6 females and 1 male. All of them were over 40 years old. Two cases reached the " suspicious diagnosis" standard and 5 cases reached the " clinical diagnosis" standard in Guidelines for the diagnosis and treatment of herb-induced liver injury. Six patients had a good prognosis effect,but another one had liver failure. This preparation is commonly used in fracture,osteoarthritis and other diseases,with remarkable curative effect. However,ADR cases and hospital cases all indicated the risk of liver injury. There was no significant correlation between the time and dose of drug use and the occurrence of liver injury.The induced-liver injury may have immunological heterogeneity,thus regular monitoring of liver function should be taken during clinical use.
