ENDOMETRIOSIS, ANKYLOSING SPONDYLITIS
This project is supported by Wu Jieping Medical Foundation (Grant No. 320.6750.2020-03-4). The latest study is the first to identify an increased risk of ankylosing spondylitis (AS) in patients with infertile endometriosis. In this study, MR analysis was performed using publicly available GWASs data. Multiple MR analysis methods (IVW, IVW-MRE) showed a causal relationship between endometriosis and AS. Patients with endometriosis have an increased risk of AS, which supports clinicians to pay more attention to the occurrence of AS in patients with infertile endometriosis.
