The role of aspartate aminotransferase to platelet ratio index (APRI) in the first trimester for the prediction of superimposed preeclampsia: A case-control study from a tertiary center
Pregnancy Hypertension(2024)
摘要
Introduction
To evaluate the role of aspartate aminotransferase to platelet ratio index (APRI) in the prediction of superimposed preeclampsia in chronic hypertensive pregnancy group in the first trimester.
Methods
The present retrospective case-control study was conducted on 258 pregnant women, including 75 patients in the isolated chronic hypertension group, 92 in the superimposed preeclampsia group, and 91 low-risk pregnant women in the control group. APRI1 was calculated from routine blood test results in the first antenatal visit, and APRI2 was calculated from prelabor routine blood test results. APRI indices and other blood count parameters were evaluated and compared between groups and with the literature.
Results
APRI1 was lower in the superimposed preeclampsia group than in the control and chronic hypertension groups, with p-values < 0.001. In the first trimester, platelet counts were higher in the superimposed preeclampsia group than in the hypertension and control groups. APRI2 was increased in the superimposed preeclampsia group compared to the control and chronic hypertension groups, with p-values 0.001 and 0.002, respectively. The optimal cut-off value for APRI1 was 0.036 (sensitivity 65.2 %, specificity 83.7 %), and for APRI2, it was found to be 0.057 (sensitivity 67.4 %, specificity 52.0 %) to predict superimposed preeclampsia.
Discussion
To the best of our knowledge, this was the first study evaluating APRI in predicting superimposed preeclampsia in the first trimester. Increased platelet counts and lower APRI were found to be valuable indices for predicting superimposed preeclampsia. Further studies are needed to determine the utility of APRI in clinical practice.
