OBJECTIVE: To investigate the diagnostic and prognostic value of the Systemic Inflammation Response Index (SIRI) in intrahepatic cholestasis of pregnancy (ICP).
METHODS: The present case-control study comprised 386 participants, including 192 women with ICP and 194 gestational age-matched pregnant women. Increased fasting biliary acid (FBA) levels (≥10 μmol/L) were accepted as ICP criteria. SIRI values were calculated for the first trimester (SIRI 1), time of diagnosis (SIRI 2), and time of delivery (SIRI 3). The ICP and control groups were compared based on SIRI values, and on obstetrical and neonatal outcomes. The ICP subgroups based on FBA levels (severe ICP [FBA ≥40 μmol/L] and mild ICP [FBA <40 μmol/L]) were also compared for SIRI and pregnancy outcomes.
RESULTS: Adverse outcomes were significantly higher in the ICP group (P < 0.001). SIRI 2 and SIRI 3 showed negative significant differences between the ICP and control groups, with P values of 0.001 and 0.009, respectively. A significant difference in ICP severity subgroups (P = 0.046) was observed for SIRI 3. In receiver operating characteristics curve analyses, optimal cut-off values for the prediction of ICP were found to be 2.01 and 2.08 for SIRI 2 and SIRI 3, respectively. A cut-off value 1.74 was determined to predict the disease severity for SIRI 3.
CONCLUSION: SIRI has clinical significance in accordance with the inflammatory etiology of ICP. SIRI might be used with other clinical and laboratory findings for ICP diagnosis and prediction.
