Propensity score analysis of liver and kidney function changes when Shenmai is parenterally administered over extended period

Abstract

Since parenterally administered Shenmai directly enters the bloodstream, avoiding gastrointestinal absorption, there are concerns as to its toxicity on the liver and kidneys. Previously, the risk of toxicity to the liver and kidneys through overdose has been discussed. This paper investigates changes in liver and kidney functions as indicated by ALT, AST, Cr and Bun, obtained from hospital information system (HIS) data, when it is administered over a longer than the recommended period of 14 days. Methods applied include: column joint analysis, logistic regression, propensity score and propensity score weighting. Results indicate that a longer course of administration does not have a significant effect on the function of liver and kidneys. However, continued monitoring of the toxicity to the liver and kidneys is a long-term and important issue; further exploration through toxicology experiments and prospective clinical research is required.
