Role of Systemic Immune Inflammatory Index to Predict Intrahepatic Cholestasis of Pregnancy by Seval Y. Ergani, Sevki Celen

Background: The goal was to investigate the change of systemic immune inflammation index (SII) in high-risk pregnant women diagnosed with intrahepatic cholestasis of pregnancy (ICP).
Methods: Between May 2018 and April 2020, we retrospectively enrolled 218 pregnant women who were followed in our hospital from the first trimester to delivery. We looked at the sociodemographics, laboratory data, SII values, Apgar ratings, and newborn birth weights of pregnant women with ICP. We also compared SII values in the first (SII 1), second (SII 2), and third trimesters (SII 3) between ICP and the control group.
Results: In the ICP group, the neutrophil level increased in the second trimester and decreased in the third trimester. The SII 2 was significantly higher in the severe ICP group, and when the SII values of the subgroups were examined, the SII 2 was significantly higher in the severe ICP group. The SII 2 showed a significant cutoff value for ICP with 92% sensitivity and 96% specificity. Again, a positive but weak correlation was found between SII 2 and SII 3 and FBA. When the neonatal outcomes were evaluated between the groups, gestational age at birth, birth weight and Apgar scores at 1 and 5 minutes were significantly lower in the ICP group.
Conclusions: The relationship between SII and ICP was investigated for the first time in the literature and a significant cutoff value was found with the SII of the 2nd day. This showed that inflammation occupies an important place in the pathophysiology of cholestasis.
