Urocortin Expression in Endometriosis: A Systematic Review.

Area of Science:

• Reproductive Medicine
• Endocrinology
• Biomarker Discovery

Background:

• Urocortin (UCN), a neuropeptide from the corticotrophin-releasing hormone family, is expressed in human endometria.
• Endometriosis research has increasingly focused on UCN expression in eutopic and ectopic tissues.

Purpose of the Study:

• To systematically review current evidence on UCN expression in tissue and blood samples from endometriosis patients.
• To evaluate UCN as a potential diagnostic biomarker for endometriosis.

Main Methods:

• Systematic literature search adhering to PRISMA guidelines across Medline, Scopus, EMBASE, and Clinicaltrials.gov (1966-2018).
• Inclusion of eight studies reporting on UCN expression in endometriosis.
• Analysis of diagnostic efficacy of UCN1 plasma levels from three studies.

Main Results:

• Evidence indicates increased UCN expression in patients with ovarian endometriomas.
• UCN levels may correlate with endometriosis disease severity.
• UCN1 plasma levels showed potential diagnostic sensitivity and specificity exceeding 80% in some studies.

Conclusions:

• Urocortin (UCN) shows promise as a biomarker for endometriosis identification and monitoring.
• Variations in study outcomes and reporting measures limit definitive conclusions.
• Further research is required to establish the predictive accuracy of UCN for endometriosis.
