High rate of allergies among women with endometriosis

Abstract

Women with endometriosis frequently suffer from autoimmune inflammatory diseases, allergies and asthma. This study was conducted to examine whether the prevalence of allergies is higher in patients with endometriosis than in the control group, and to show potential correlation with endometriosis stages. We evaluated the medical files of 501 women with laparoscopically-diagnosed endometriosis and 188 women without endometriosis enrolled in Yale University Hospital. Main outcome measures used were allergy on medications, complaints of sinus or perennial allergic rhinitis, asthma, family history of allergic disease, and correlation with stages of endometriosis. Our results indicated that the overall risk of women with endometriosis and positive history of allergies was 4.28 (95% CI, 2.96.3) (p < 0.001). Significant excesses were identified for medications, sinus allergic rhinitis, and asthma; also, women with endometriosis were significantly more likely to report a positive family history of allergies. Overall, our study indicated a link between endometriosis and increased risk of allergic autoimmune disorders that should further be explored. © 2012 Informa UK, Ltd.
