This study investigated the levels of serum ferritin and 25-hydroxyvitamin D in pregnant women with preeclampsia and analyzed their predictive value for premature birth. The results showed that these markers were abnormally expressed in pregnant women with preeclampsia and were associated with premature birth.
This study aimed to investigate the expression levels of serum ferritin (SF) and 25-hydroxyvitamin D (25-[OH]-D) and analyze their predictive value for premature birth in pregnant women with preeclampsia. Between December 2018 and December 2021, 104 pregnant women with preeclampsia were selected as the observation group and 52 pregnant women with normal blood pressure as the control group. The observation group were divided into occurrence and nonoccurrence groups according to gestational age at birth. Relevant laboratory indicators were examined in both the occurrence and nonoccurrence groups, and the predictive value of SF and 25-(OH)-D levels for premature births in pregnant women with preeclampsia was analyzed. The incidence of premature delivery in the 104 pregnant women with preeclampsia was 20.19% (21/104). Pre-pregnancy body mass index (BMI), systolic blood pressure, diastolic blood pressure, 24 hours urinary protein, triglycerides, and SF levels of the pregnant women in the observation group were significantly higher, and the 25-(OH)-D levels were significantly lower, than those in the control group (P < .05). Furthermore, the pre-pregnancy BMI, systolic blood pressure, diastolic blood pressure, 24 hours urinary protein, and SF levels of pregnant women in the occurrence group were significantly higher, and the 25-(OH)-D levels were significantly lower, than those in the nonoccurrence group (P < .05). Logistic regression analysis showed that high pre-pregnancy BMI, systolic blood pressure, diastolic blood pressure, 24 hours urinary protein, and SF levels were risk factors for premature birth in pregnant women with preeclampsia (OR > 1, P < .05) and that high serum 25-(OH)-D was a protective factor (OR < 1, P < .05). In conclusion, SF and 25-(OH)-D levels are abnormally expressed in pregnant women with preeclampsia and are associated with premature birth in these women.
