The Relationship of First Trimester Vitamin D, Vitamin B12 and Ferritin Levels with Preeklampsia

Purpose: We aimed to investigate the relationship between first trimester vitamin D, vitamin B12 and ferritin levels with preeclampsia and neonatal outcomes. Materials and Methods: 191 patients diagnosed with preeclampsia (PE) and 99 healthy pregnant women were included in the study.. Age, gravida, parity, body mass index (BMI), mode of delivery, birth weight, APGAR score, neonatal intensive care unit (NICU) admission and delivery week were recorded. First trimester vitamin D, vitamin B12 and ferritin levels were determined in laboratory analyzes. Evaluation was made by separating three groups as without PE, with PE and with severe PE. Results: Differences were found between BMI measurements, birth weeks, birth weights and NICU acceptance values (p=0.003; 0.001; 0.001; 0.001 respectively). Babies in the PE group had lower mean birth weeks, birth weights and APGAR scores. In the PE group had a higher rate of cesarean section (p=0.001). The vitamin D level of the PE group was lower than the group without PE. It was found that the vitamin D level decreased in proportion to the severity of PE. The B12 level of the non-PE group was higher than PE group (p=0.001). The ferritin level of the non-PE group was found to be lower than the PE group (p=0.001). Conclusion: Low vitamin D and B12 levels and high ferritin levels in the first trimester may be beneficial in predicting preeclampsia. We think that especially vitamin D, B12 and iron supplementation is a simple but effective approach to reduce perinatal morbidity and mortality in preeclampsia.
