Abstract

Objective: To assess the association between aspartate aminotransferase (AST) to platelet count ratio index (APRI score), during the first and third trimesters of pregnancy and the development of intrahepatic cholestasis in pregnancy (ICP). Methods: Case–control study was conducted. The study included patients diagnosed with ICP by elevated bile acids (n = 118) and a control group of women with symptoms such as elevated liver enzymes or pruritus with normal level of bile acids (n = 127) who attended a large tertiary teaching medical center between the years 2014 and 2021. The groups were compared in terms of obstetrical characteristics, perinatal outcomes, first- and third-trimester laboratory tests, and APRI scores during the first and third trimester. A receiver operating characteristic (ROC) analysis was performed to determine the APRI score cutoff value that could predict ICP. Results: The third-trimester APRI scores of patients with ICP were significantly higher than those of the control group (P < 0.001). The ROC analysis revealed that the cutoff value for the APRI score was 0.42 with 65.3% sensitivity and 73.2% specificity. Conclusion: Our results suggest that the third-trimester APRI score is positively associated with ICP.
