Background/Aims:
Guidelines recommend that steroid treatment for ulcerative colitis (UC) is tapered or withdrawn within 3 months of initiation, and thiopurine treatment or advanced therapy is administered for steroid-dependent UC. This study aimed to clarify real-world treatment patterns and outcomes in patients with steroid-dependent UC in Japan.
Methods:
A retrospective analysis of JMDC (Japan Medical Data Center) claims data was conducted to identify patients with a new UC diagnosis between June 2010 and September 2019. Index dates were the UC treatment start date (initiation of any UC treatment), steroid dependence/resistance confirmation date (identification of steroid-dependent UC), and treatment intensification date (initiation of thiopurine treatment/advanced therapy).
Results:
Of 5,602 patients with newly diagnosed UC, 986 (17.6%) initiated steroids within 12 months (85.4% [842/986] received 5-aminosalicylic acid at the UC treatment start date). Of these 986 patients, 429 (43.5%) were classified as steroid-dependent (steroid dependence/resistance confirmation date). Of these 429 patients, 128 (29.8%) initiated thiopurine treatment and 75 (17.5%) initiated advanced therapy (treatment intensification date); 226 (52.7%) continued with steroids only. Across these groups, 3-6% discontinued steroids within 3 months of initiation. Hospitalization due to UC in the 12 months after the treatment intensification date occurred in 24.2% (31/128) and 18.7% (14/75) of patients who initiated thiopurine and advanced therapy, respectively.
Conclusions:
Over half of patients with steroid-dependent UC continued steroid treatment only. Steroid discontinuation within 3 months of initiation was low, irrespective of whether thiopurines or advanced therapy were initiated. Management of patients with steroid-dependent UC in Japan requires further treatment optimization toward guideline adherence.

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
