SAT-025 Increased Occurrence of Anemia, Gastrointestinal and Liver Diseases in Women with Turner Syndrome - a Nationwide Registry Study

Background: Gastrointestinal disorders, such as celiac disease, inflammatory bowel diseases and liver disease have previously been described with increased occurrence in women with Turner syndrome. However, evidence towards increased occurrence of bleeding disorders and anemia are sparse. Likewise, the impact of hormone replacement therapy on gastrointestinal disorders remains unknown. Aim: To investigate the risk of bleeding disorders, anemia, gastrointestinal and hepatological disease in women with TS compared with the female background population and to assess the effect of HRT on these conditions. Design: National cohort study Method: 1,156 females with TS diagnosed during 1960–2014 were identified using the Danish Cytogenetic Central Registry and linked with personal-level data from the National Patient Registry and the Medication Statistics Registry. Statistics Denmark randomly identified 115,577 age-matched female controls. Negative binomial regression was used to analyze hospital discharge diagnoses. Medical prescriptions, mortality and the effect of hormone replacement therapy were estimated using stratified Cox regression. Results: The risk of anemia, coagulation disorders and gastrointestinal hemorrhage were all increased three-fold in women with TS compared with controls. Gastrointestinal disorders were twice as frequent in TS individuals, with a three-fold increased risk of inflammatory bowel disease and a twelve-fold increased risk of liver disease and elevated liver enzymes. Both gastrointestinal and hepatological mortality were increased three-fold in TS women. Conclusion: Anemia, gastrointestinal hemorrhage, inflammatory bowel disease is more frequent in women with Turner syndrome compared with controls. The risk of liver disease may be higher than previously reported.
