AI Article Synopsis

  • The study reviews the impact of specific MMP gene polymorphisms on the risk of endometriosis and adenomyosis, focusing on MMP-1, MMP-2, MMP-3, and MMP-9.
  • A significant association was found only for the MMP-1 -1607 1G/2G polymorphism, suggesting it increases susceptibility to these conditions.
  • The review calls for more comprehensive research to explore gene interactions and their environmental influences on these diseases.

Article Abstract

Matrix metalloproteinase (MMP) promoter polymorphisms are considered to play roles in the aetiology of endometriosis and adenomyosis, however, the evidence available are inconsistent. We aimed to systematically review the asscociation between MMP-1 -1607 1G/2G MMP-2 -735 C/T, MMP-3 -1171 5A/6A and MMP-9 -1562 C/T polymorphisms and the risk of endometriosis and adenomyosis. A systemic search was conducted in Ovid, PubMed, Chinese National Knowledge Infrastructure and ChineseWanfang Database.We used the pooled odds ratio (OR) and their corresponding 95% confidence interval (CI) to calculate the statistical power. Besides, we evaluated the quality of individual studies based on Newcastle-Ottawa scale. A total of 13 papers with 18 studies conformed to our inclusion criteria. We observed a significant association between MMP-1 -1607 1G/2G polymorphism and the susceptibility of endometriosis and adenomyosis under recessive model (OR = 1.25, 95%CI = 1.03-1.53, P = 0.03). While no significant association was found in MMP-2 -735 C/T, MMP-3 -1171 5A/6A and MMP-9 -1562 C/T polymorphisms. This systemic review and meta-analysis suggested that theMMP-1 -1607 1G/2G polymorphism might play an important role in the risk of endometriosis and adenomyosis. Further, more well-designed and large-scale studies regarding gene-gene and gene-environment interactions are needed in the future.

Endometriosis and adenomyosis are prevalent causes of infertility, often coexisting in a significant proportion of patients. Although endometriosis typically does not negatively impact assisted reproductive technology (ART) outcomes, the presence of coexisting adenomyosis, mainly non-severe external forms, may slightly influence IVF/ICSI success rates. However, this impact is often minimal and may result in insignificant changes in statistical analyses.

Recent research has proven that peripheral (PS) and central sensitization (CS), mental health, and myofascial dysfunction all play a role, alongside nociception, in the genesis and in the perpetuation of endometriosis' symptoms. However, such components of pain are still largely ignored in clinical practice, although not considering such contributors may entail serious consequences on women's health, including the choice of unnecessary surgery and leaving the real causes of pain untreated. At the present time, we are facing a paradox by which 25-40% of women who undergo laparoscopic surgery for pelvic pain do not have an obvious diagnosis, while the percentage of women with endometriosis who have signs of CS, of depressive or anxiety disorders, or who have an increased pelvic muscle tone ammounts to 41-55%, 15-88% and 28-73%, respectively.

Adenomyosis is a benign condition where ectopic endometrial glandular tissue is found within the uterine myometrium. Its impact on women's reproductive outcomes is substantial, primarily due to defective decidualization, impaired endometrial receptivity, and implantation failure. The exact pathogenesis of the disease remains unclear, and the role of autophagy in adenomyosis and its associated infertility is not well understood.

Introduction: Ovarian adenomyoma is a rare gynecological tumor with a high misdiagnosis rate, leading many patients to undergo unnecessary surgeries that may affect fertility. Menstrual abdominal pain is the most common symptom, and auxiliary examinations often cannot clarify its nature. It often relies on intraoperative diagnosis, and surgical resection can achieve good therapeutic effects.
