Gremlin-1 Level In Polycystic Ovary Syndrome And Its Clinical Correlations; A Case Control Study.

Objectives: To evaluate the involvement of the level of Gremlin-1 in serum and follicular fluid in the diagnosis of polycystic ovary syndrome. Method: The case-controlstudy was conducted at the Kafrelsheikh University Hospital, Egypt, from September 2021 to February 2022, and comprised women with polycystic ovary syndrome and healthy controls. All participants were subjected to a detailed clinical assessment, complete clinical examination and hormonal profile assessment. Gremlin1 concentrationsin plasma and follicular fluid samples were assessed by a double-antibody sandwich enzyme-linked immunosorbent assay kit. Data was analysed using SPSS 20. RESULTS: Of the 90 subjects, 45(50%) were patients with a mean age of 29.53±4.82 years, and 45(50%) were controls with a mean age of 30.89±6.08 (p>0.05). Mean weight, body massindex, waist circumference and waist-hip ratio were significantly higher in patients compared to controls (p<0.05). Serum and follicular fluid Gremlin-1 levels were significantly higher in the patient group (p<0.05). The best cutoff of serum Gremlin-1 in the diagnosis of polycystic ovary syndrome was ≥1.325ng/ml with area under curve 0.857,sensitivity 93.3%,specificity 68.9%, positive predictive value 75%, negative predictive value 91.2% and overall accuracy 81.1%. The best cutoff of follicular fluid Gremlin-1 in the diagnosis of polycystic ovary syndrome was ≥1.725ng/ml with area under curve 0.789,sensitivity 73.3%,specificity 68.9%, positive predictive value 70.2%, negative predictive value 72.1% and overall accuracy 71.1%. CONCLUSIONS: There was a strong correlation between serum and follicular Gremlin-1 levelsin polycystic ovary syndrome patients.

Assessment Of Endometrial Integrin Beta 5 In Women With Unexplained Recurrent Pregnancy Loss.

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.
