May human epididymis 4 protein play a role in the etiopathogenesis of hemolysis, elevated liver enzymes and low platelets (HELLP) syndrome?

摘要

Aim Hemolysis, elevated liver enzymes, and low platelets (HELLP) syndrome is an extremely advanced form of preeclampsia. Currently, there is no parameter or marker to predict this syndrome; however, it is emphasized that vascular endothelial damage and abnormal immune responses can be the possible etiologies of HELLP syndrome. It is known that human epididymis protein 4 (HE4) is a protease inhibitor and previous studies have shown that HE4 protein levels are increased in many malignancies and inflammatory conditions. Considering that metalloproteinases may also play a role in endothelial damage, which is thought to be involved in the etiopathogenesis of HELLP syndrome, we thought that HE4 protein, which is a protease inhibitor, may be associated with vascular damage. We aimed to investigate the relationship between HELLP syndrome and HE4 protein and to identify a biomarker that can be utilized in the diagnosis of HELLP syndrome.
