Abstract Objective: To examine whether plasma levels of aspartate transaminase (AST) and alanine transaminase (ALT) during the first 20 weeks of pregnancy can predict preeclampsia in the second half of pregnancy. Methods: The study population included 15010 registered births. Receiver operating characteristic (ROC) curve analysis was used to describe the relationship between different values of AST and ALT during the first 20 weeks of pregnancy in the prediction of preeclampsia. Results: Using ROC curve analyses, elevated ALT levels were significantly associated with both mild preeclampsia (P<0.001) and severe preeclampsia (P=0.032). However, an ALT level of 50IU/L had a sensitivity of only 3.3% (despite a specificity of 97%) in the prediction of severe preeclampsia. While no significant association was noted between AST levels and mild preeclampsia (P=0.669), elevated levels of AST during this period were significantly associated with severe preeclampsia (P=0.027). However, AST of 50IU/L had a sensitivity of only 2.0% (despite a specificity of 98%) in the prediction of severe preeclampsia. Conclusions: Higher levels of the liver enzymes AST and ALT during the first 20 weeks of pregnancy are associated with higher risk for the development of severe preeclampsia in the second half of the pregnancy. Nevertheless, there is no clinical cut-off value that can be practically used for the prediction of preeclampsia.
