Introduction: Preeclampsia can lead to a number of adverse maternal and perinatal effects. The association between iron status [serum iron, ferritin and total iron-binding capacity (TIBC)], unsaturated iron-binding capacity, hepcidin, interleukin-6 (IL-6) levels and preeclampsia is not fully understood. Objective: To assess the levels of iron status, hepcidin and interleukin-6 in women with preeclampsia compared with healthy pregnant women. Method: A case-control study (60 women were recruited in each group) was conducted at Saad Abuelela Maternity Hospital in Khartoum, Sudan. Sociodemographic and clinical data were gathered through a questionnaire. The levels of iron status, hepcidin and IL-6 were measured using applicable methods. Results: There was no significant difference in the median [interquartile range (IQR)] of age, parity or body mass index between the two groups. Moreover, the median (IQR) of the iron status, hepcidin and interleukin-6 did not differ between women with preeclampsia and healthy controls. There were no significant correlations between haemoglobin, hepcidin and IL-6. There were also no significant correlations between serum iron, serum ferritin, hepcidin and IL-6. However, there was a significant positive correlation between hepcidin and IL-6 (r = 0.393, p = 0.002). Conclusion: In this study, women with preeclampsia had levels of iron status, hepcidin and IL-6 similar to those observed in healthy pregnant women. There was no significant correlation between iron status, hepcidin and IL-6. [ABSTRACT FROM AUTHOR]

This document is a corrigendum published in the journal Frontiers in Physiology. It corrects an error in the keywords of an article titled "Maternal serum iron status, hepcidin and interleukin-6 levels in women with preeclampsia." The error was the use of "IL-6" instead of "interleukin-6" as a keyword. The authors apologize for the mistake and clarify that it does not affect the scientific conclusions of the article. The corrigendum also includes information about the publisher's note, open access, and contact information for correspondence. [Extracted from the article]
