Identification and analysis of the risk of liver-related adverse drug reaction in pregnant women / 临床肝胆病杂志

ABSTRACT

Objective To investigate the potential medication risk by identifying and analyzing the features of liver-related adverse drug reaction (ADR) in pregnant women. Methods A retrospective study was performed for the reports on liver-related ADR in pregnant women from January 1, 2012 to December 31, 2016 in HILI Cloud (hilicloud.net). Main clinical features and medication rules were analyzed, and reporting odds ratio ( ROR ) was used to analyze the relative risk of related drugs. Results Methotrexate, mifepristone, and ritodrine were the high-frequency drugs reported for liver-related ADR in pregnant women and were mainly used for termination of ectopic pregnancy and treatment of hydatidiform mole. The relative risk analysis of liver-related ADR showed that in pregnant women, the use of methotrexate ( ROR =37.52, 95% confidence interval [ CI ]=31.35-44.89), progesterone ( ROR =7.33, 95% CI 2.75-19.59), and dydrogesterone ( ROR =6.58, 95% CI 2.20-19.69) was strongly associated with the risk of liver injury, and the association of methotrexate with the risk of liver injury in pregnant women was significantly stronger than that in non-pregnant women ( ROR =1.71, 95% CI 1.47-4.36). Conclusion The potential risk of liver injury should be taken seriously in pregnant women using the drugs such as methotrexate and progesterone, so as to avoid serious adverse reactions.
