ABSTRACT
OBJECTIVE: To evaluate the aspartate aminotransferase to platelet ratio (APRI) score as a predictive and prognostic test in intrahepatic cholestasis of pregnancy (ICP).
METHODS: This study was conducted in 198 patients diagnosed with ICP and 204 healthy pregnant women who presented to a tertiary center between 2019 and 2022. APRI scores; laboratory findings in the first, second, and third trimesters; and perinatal outcomes were compared between the two groups. The ICP group was evaluated for correlation between APRI scores and composite adverse outcomes. Two different receiver operating characteristic analyses were performed to determine optimal cutoff values of predictive APRI score of ICP and composite adverse outcomes in patients with ICP.
RESULTS: Aspartate aminotransferase values and APRI scores were significantly higher in the ICP group in all trimesters (P < 0.001). The optimal cutoff values of APRI scores to predict ICP for the first, second, and third trimesters were 0.101 (79.7% sensitivity, 79.6% specificity), 0.103 (78.4% sensitivity, 76.3% specificity), and 0.098 (72.5% sensitivity, 72% specificity), respectively. APRI scores were statistically higher in patients with ICP with composite adverse outcomes in all trimesters (P values of 0.03, 0.04, and 0.01, respectively).
CONCLUSION: APRI score was found to be a valuable predictor of ICP and its adverse outcomes during the entire pregnancy.
