The Comorbidity of Endometriosis and Systemic Lupus Erythematosus: A Systematic Review.

Autoimmune diseases manifest in genetically predisposed individuals exposed to certain triggers that aggravate immune dysfunction and result in an exacerbated immune response in the form of hyperactivity to both the humoral and cell-mediated response. The devastating reality apart from the severity of the disease is that multiple immune diseases could co-occur, increasing the patient's physical, psychological, and financial burden. Autoimmune diseases are utterly deranging. One of the dreadful autoimmune diseases is systemic lupus erythematosus (SLE). SLE is a rheumatological disease that affects multiple systems, and there are no predictors to know which system will be affected in the future. It could affect the mucocutaneous system. It could also present with hematological, rheumatological, neuronal, renal, pulmonary, and cardiac manifestations. SLE is prevalent in females, predominantly in the childbearing age group. The pharmacological therapy and bombarding pathophysiology of the disease lead to obstetrical and gynecological complications such as infertility, abortion, miscarriage, and stillbirth. Over the past decade, the autoimmune disease comorbidity increased eminently. One of the common associations is rheumatological diseases (like rheumatoid arthritis, Sjogren syndrome, and SLE) with gynecological diseases (e.g., endometriosis and uterine fibroids). SLE and endometriosis have strong associations, and the prevalence of each condition is relatively high among the female population.  is a chronic disease triggered by inflammation, hormonal milieu, and other predisposing factors that lead to the fibrous tissue that lines the uterus (endometrial tissue) to be implanted at sites other than the uterus, commonly in the peritoneum and mesentery. The pathogenesis of this association remains unexplained. The approved theory is that their immune dysfunction is summarized by the elevated humoral and cell-mediated response, which leads to an attack to the epithelium, mesothelium, and Serosa and leads to fibrous tissue deposition in different sites other than the uterus. Statistical evaluations have shown a remarkable association between autoimmune diseases and both gynecological and nongynecological diseases.
