Abstract

Introduction: Hepcidin is a hormone that regulates systemic iron homeostasis and is mostly produced in the liver. In pregnant women with inflammation, there are two opposing mechanisms in hepcidin expression: the suppression of hepcidin synthesis by pregnancy and the induction of hepcidin by inflammation. These conditions must receive special attention so clinicians can properly treat and manage pregnant women with inflammation. Therefore, this study aims to prove changes in hepcidin and serum iron levels in pregnant mice with inflammation.

Method: This study involved sixteen-second-week pregnant mice divided into two groups. Pregnant mice were injected with lipopolysaccharide (LPS) Escherichia coli serotype O111:B4 as much as 1 µg/g body weight intraperitoneally as the treatment group. In contrast, pregnant mice were injected with phosphate buffer saline (PBS) as a control group. Serum was measured using ELISA to determine hepcidin levels and colorimetry to determine serum iron. Mice livers were measured using Real-Time PCR to determine Hamp1 mRNA expression. The data obtained were analyzed using an independent t-test.

Result: Our results show that pregnant mice with inflammation show there was no difference in Hamp1 mRNA expression (p-value=0.163) and hepcidin level (p-value=0.789), but there was a significant difference in serum iron level (p-value=0.035).

Conclusion: This study demonstrates that inflammation in pregnancy does not affect changes in Hamp1 expression and hepcidin level but reduces serum iron, which could be caused by regulating hepcidin in the fetus.
