Autoimmune Diseases and Premature Ovarian Insufficiency

TOPLINE: 

Women with premature ovarian insufficiency (POI) have a 2.6 times higher prevalence of severe autoimmune diseases before diagnosis and a 2- to 3-fold increased risk for these diseases after diagnosis.

METHODOLOGY:

• Researchers conducted a population-based registry study including 3972 women diagnosed with spontaneous POI between 1988 and 2017.
• A total of 15,708 female population controls matched by age and municipality of residence were included for comparison.
• Autoimmune disease diagnoses were evaluated from childhood until the end of 2017 using the Hospital Discharge Registry.
• Women with a history of cancer or bilateral oophorectomy were excluded from the study.

TAKEAWAY:

• Women with POI had a 2.6 times higher prevalence of severe autoimmune diseases before diagnosis compared to controls (odds ratio [OR], 2.6; 95% CI, 2.2-3.1).
• The prevalence of specific autoimmune diseases such as polyglandular autoimmune diseases (OR, 25.8; 95% CI, 9.0-74.1) and Addison disease (OR, 22.9; 95% CI, 7.9-66.1) was significantly higher in women with POI.
• The standardized incidence ratios for being diagnosed with a severe autoimmune disease after POI diagnosis was 2.8 (95% CI, 2.3-3.4) during the first 3 years, decreasing to 1.3 (95% CI, 1.1-1.6) after 12 years.
• No significant difference was found in the prevalence of diabetes type 1 and ankylosing spondylitis between women with POI and the reference cohort.

IN PRACTICE:

”The study results strengthen the hypothesis that autoimmune mechanisms play an important role in the pathogenesis of POI. Future studies should focus on the immunological mechanism of POI from preventative and curative perspectives,” wrote the authors of the study.

SOURCE:

The study was led by Susanna M. Savukoski, Oulu University Hospital in Oulu, Finland. It was published online in Human Reproduction.

LIMITATIONS: 

The study included only autoimmune disorders diagnosed in specialized health care, which may underestimate the overall prevalence of autoimmune disorders in women with POI. Additionally, the study did not account for confounders such as body mass index and smoking, which are associated with the risk for autoimmune disease and POI.
