The relationship between ulcerative colitis activity and vitamin D, mean platelet volume and platelet distribution width

Abstract

Aim: In our study, we aimed to show the relationship between ulcerative colitis activity and vitamin D, platelet distribution width, and mean platelet volume. Material and Method: Our study was conducted at the Internal Medicine Clinic. We planned to cross-sectionally investigate the severity of ulcerative colitis activity, vitamin D level, mean platelet volume, platelet distribution width and other laboratory parameters of patients admitted to the hospital. The Truelove and Witts’ severity index was used to determine ulcerative colitis activity. In accordance with the guidelines, serum 25-OH vitamin D levels of >30 ng/ml were considered as sufficient vitamin D, 20-30 ng/ml as vitamin D insufficiency,
