Endometriosis is a chronic gynecological condition that commonly affects up to 15% of women of childbearing age [1]. Historically, it was believed to impact the abdominal cavity primarily and, in most cases, only the pelvic region. However, recent research indicates it is a systemic condition [2]. While the precise causes of endometriosis remain elusive, immune system irregularities are evident. A meta-analysis explored the link between endometriosis and autoimmune conditions [3]. Although additional comprehensive studies are needed to supplement existing research, substantial evidence suggests a close connection between endometriosis and the immune system.
Endometriosis is a benign condition characterized by the growth of cell clusters resembling the uterine lining, or endometrium, outside the uterus [4]. These cell clusters, known as endometriosis lesions, can manifest in various locations, including the muscular layers of the uterine wall, the vagina, the peritoneum, the urinary bladder, and the ureter. Additionally, they can affect the intestines, lungs, liver, and skin scars.
Traditionally, endometriosis has been associated with cyclic lower abdominal pain that may radiate to the back and legs. It is also a recognized contributor to reduced fertility and infertility [5]. However, recent research reveals systemic inflammatory responses and heightened pain sensitization in individuals with endometriosis [6]. Furthermore, a recent study has established a connection between endometriosis and rheumatoid arthritis [7].
The precise causes of endometriosis remain elusive despite ongoing research efforts. While multiple theories have been proposed, none comprehensively explain all aspects of the condition [8]. Consequently, experts now believe that endometriosis likely arises from a combination of hormonal, immunological, anatomical, and (epi-)genetic factors.
Some of the critical theories regarding the development of endometriosis include:
A total of 26 studies adhering to specific criteria were incorporated into this meta-study. These studies collectively provided evidence indicating an association between endometriosis and autoimmune conditions. Subsequently, four studies were chosen in a further selection process. These studies not only met the qualitative standards of the study design but also demonstrated a scientifically significant relationship between endometriosis and autoimmune conditions.
The study authors emphasize the need for further research to delve into the relationship between endometriosis and autoimmune conditions.
The present study successfully established a connection between endometriosis and certain autoimmune conditions, yet this does not rule out the possibility of links with others. Additionally, it remains essential to determine whether endometriosis triggers autoimmune conditions or if both share common underlying causes, such as similar or identical triggers.
As mentioned earlier, a recent study [7] exploring the association between endometriosis and the autoimmune condition of rheumatoid arthritis (RA) provides insight into this matter. In this study, women with endometriosis were observed over an extended period, and it was evident that endometriosis did not appear to be a consequence of RA. This suggests a more plausible scenario where the autoimmune disease follows endometriosis or both conditions share a common cause.
The study’s authors urge healthcare providers to remain vigilant when patients present with relevant symptoms and are diagnosed with an autoimmune condition or endometriosis.
Summary:
Endometriosis, affecting a significant percentage of women of reproductive age, has remained a mystery in its cause. Recent research suggests it is a systemic condition, prompting a study examining the link between endometriosis and autoimmune conditions. This study revealed connections between endometriosis and at least 6 of them. Further investigations are needed to elucidate how these conditions interact, whether one triggers the other, or if they share common underlying causes.
