Assessment of endometrial integrin beta 5 in women with unexplained recurrent pregnancy loss

Résumé

Objectives: To examine the relationship between endometrial integrin beta 5 level and risk of recurrent pregnancy loss. Method: The descriptive, prospective, observational, case-controlstudy was conducted at the Kafrelsheikh University Hospital, Egypt, from January to May 2022, and comprised women aged up to 35 years with at least 1 live birth delivery beyond 20-week gestation with normal thyroid and prolactin levels. Age-matched normal fertile women were enrolled as controls. All the participants were subjected to detailed history and complete clinical examination. Endometrial integrin beta 5 was assessed using an antibody sandwich enzyme-linked immunosorbent assay. Data was analysed using SPSS 20. RESULTS: Of the 50 subjects, 25(50%) were cases with a mean age of 26.72±2.64 years, and 25(50%) were controls with a mean age of 25.36±2.16 years. The integrin beta 5 level was significantly lower among the cases than the controls (p<0.05). The best cut-off level of serum integrin beta 5 was ≤2.5765 with area under curve 0.886, sensitivity 88%, specificity 76%, positive predictive value 78.6%, negative predictive value 86.4%, and accuracy 82%. CONCLUSIONS: Therewas an inverse correlationbetween endometrial integrinbeta 5 andthe risk ofrecurrentpregnancy loss.
