Corticosteroid Treatment at Diagnosis: An Analysis of Relapses, Disease Extension, and Colectomy Rate in Ulcerative Colitis

Background: Ulcerative colitis is a chronic relapsing disease usually treated with mesalamine. The need of steroid therapy at diagnosis is generally considered as a poor prognostic factor. Aims: The aim of our study was to assess whether patients treated with corticosteroids at diagnosis have more clinical relapses, disease progression, or an increased risk of colectomy during a 5-year follow-up. Methods: We retrospectively evaluated patients who had received diagnosis of ulcerative colitis with a 5-year follow-up. Relapse was defined as a worsening of symptoms requiring an increase in medical treatment. Progression of disease was defined as a proximal extension of mucosal involvement, comparing the colonoscopy performed 5 years after diagnosis with the first one. The need of corticosteroid treatment at diagnosis was correlated to number of relapses, disease progression, and colectomy rate. Results: We included 230 patients, 116 of them (50%) treated with steroids at diagnosis. Multivariate analysis demonstrated that there is a strong correlation between corticosteroid use and number of relapses (p < 0.01), as well as with disease progression (p < 0.05). Seventeen patients (7.4%) underwent colectomy, but the correlation with steroids was not statistically significant. Conclusions: These data provide evidence that the need of corticosteroids at diagnosis is associated with a worse clinical outcome
