BACKGROUND AND AIMS: To analyze the prevalence of hyperferritinemia in pregnant women with preeclampsia and its association with adverse perinatal outcomes.
METHODS: A cross-sectional study carried out in 2017 with a convenience sample of pregnant women with preeclampsia attended at a high-risk maternity hospital in Alagoas, Brazil. Socioeconomic, lifestyle, clinical and biochemical data were collected through a structured questionnaire. Type of delivery, gestational age, weight and length at birth, and Apgar score were analyzed as outcome variables. Women were dichotomized according to the serum ferritin level (150 ng/mL). Poisson regression models were used to analyze the effect of hyperferritinemia on the outcome variables. Estimates were presented as prevalence ratio with 95% confidence intervals (PR [95% CI]).
RESULTS: Based on the Fisher's exact statistical teste and in the proportions of the neonatal outcome (birth weight), with a statistical significance of 5%, the statistical power of the sample studied was 83%. Two hundred six pregnant women with preeclampsia were recruited, which 8.74% presented hyperferritinemia. Except for ferritin level, there were no differences in C-reactive protein (CRP), hemoglobin, Glutamate Oxaloacetate Transaminase (GOT) and Pyruvic Glutamic Transaminase (PGT) levels between women with or without hyperferritinemia. After adjusting for potential confounders, hyperferritinemia was associated with low birth weight (2.19 [2.13-3.89 95%CI]), low birth length (7.76 [2.52-23.8 95% CI]) and being born small for gestational age (3.14 [1.36-7.28 95% CI]).
CONCLUSION: In the presence of hyperferritinemia, preeclampsia patients were associated with a higher rate of unfavorable neonatal outcomes.
