| description | Introduction: Endometriosis is an oestrogen dependent gynaecological disease, having endometrial glands and stromal tissues outside the intrauterine locations. The aetiology and pathogenesis of endometriosis is still unclear and it affects a large proportion of reproductive age women. It’s a heterogeneous disease and is found to be associated with hormonal and histological alterations. Studies indicate that mutation in aromatase (CYP19) gene is involved in a number of inflammatory diseases and CYP19 rs 2470152 site polymorphism may help to find its relation to susceptibility to endometriosis.
Aim: To ascertain the relationship between changes in histological architecture in endometrial cells during endometriosis with circulating hormone levels, stress parameters and aromatase (CYP19A1) gene polymorphism {Single Nucleotide Polymorphism (SNP) rs 2470152}.
Materials and Methods: This was a hospital-based case-control study where all patients and controls were recruited from the Outpatient Department (OPD) of the Sir Sunderlal Hospital, Department of Obstetrics and Gynaecology, Institute of Medical Sciences, Banaras Hindu University (BHU), Varanasi, India from March 2016-March 2019, and a total 300 subjects, 120 endometriosis patients and 180 healthy controls were studied. Histological studies were done by Haematoxylin and Eosin (H&E) staining in the endometrial tissues of patients and controls. Genotyping of SNP rs 2470152 was conducted by Polymerise Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) method on genomic Deoxyribonucleic Acid (DNA) isolated from patients and control blood. Student’s t-test was used to compare the mean for the two independent groups. Allele and genotype distribution among groups were evaluated using the Chi-squared test and Fisher’s-Exact test.
Results: In the present study, all the subjects were in the age group of 20-50+ years where 20-40 years age group were premenopausal and 40-50+ year were perimenopausal. Significant histological changes were observed in the endometrial glands and stroma of the endometrium tissues of the diseased women compared to the healthy controls. Various pathological entities were altered in circulating blood plasma of patients than to control. For polymorphism studies allele (T,C) (p=0.002*) and genotypic (TT, TC and TT) (p<0.001*) frequencies were found significantly variable in endometriosis patients in comparison of controls.
Conclusion: The present study showed that endometrial tissue undergoes a lot of pathological changes during a disease and this may be due to significantly altered expression of aromatase gene leading to higher oestrogen level, causing this disease and its proliferation. Aromatase (CYP19A1) gene polymorphism was found significantly associated, and other factors may be affecting aromatase directly or indirectly in steroidogenic pathway. |
