AbstractThis study aims to investigate the predictive values of serum placental growth factor (PIGF), total cholesterol (TC), and triglycerides (TG) in the context of intrahepatic cholestasis of pregnancy (ICP). This retrospective case control study recruited pregnant women from January 2021 to December 2021 at the Maternal and Child Health Hospital of Hunan Province, encompassing pregnant women diagnosed with ICP and those with unremarkable prenatal examinations. A total of 433 pregnant women were included, among whom 167 were diagnosed with ICP after 24 weeks of pregnancy. Patients with ICP exhibited an average age of 31.30 ± 4.54 years and an average pregnancy week at delivery of 37.63 ± 1.45 weeks. Multivariable regression analysis showed that the pregnancy week at delivery (OR = 0.823, 95% CI: 0.769-0.879, P < .001), PIGF (OR = 0.994, 95% CI: 0.992-0.996, P < .001), TC (OR = 1.955, 95% CI: 1.586-2.409, P < .001), and TG (OR = 3.786, 95% CI: 2.655-5.399, P < .001) were independent risk factors for ICP. The area under the curve values for PIGF, TC, and TG in predicting ICP were 0.858 (95% CI: 0.822-0.893), 0.721 (95% CI: 0.670-0.772), and 0.830 (95% CI: 0.788-0.871), respectively. However, their combination yielded an area under the curve value of 0.922 (95% CI: 0.898-0.946). The composite assessment of PIGF, TC, and TG demonstrates potential efficacy in predicting ICP among pregnant women.Copyright © 2023 the Author(s). Published by Wolters Kluwer Health, Inc.
