title: Oral budesonide for maintenance of remission of Crohn's disease: a pooled safety analysis.
abstract: BACKGROUND
  Budesonide exhibits similar efficacy to systemic glucocorticosteroids (GCSs) in Crohn's disease (CD), but with fewer adverse events (AEs). Aim To evaluate budesonide's safety profile in CD patients, in particular, incidences of clinically important AEs known to be associated with systemic GCSs.
  
  
  METHODS
  Five 1-year, double-blind, placebo-controlled trials evaluating budesonide for mild-to-moderate CD were pooled for analysis.
  
  
  RESULTS
  The highest incidence rates of AEs were gastrointestinal- and endocrine systems-related in both groups (budesonide 6 mg/day, n = 208; placebo, n = 209). Incidence rates were similar, except for higher incidence of endocrine disorders in budesonide versus placebo patients (P = 0.0042) caused by a higher overall occurrence of cutaneous GCS symptoms (P = 0.0036) in the budesonide group; differences in individual symptoms were nonsignificant. Percentage of patients with normal adrenal function was significantly lower at 13 weeks (three of five studies), but not at 52 weeks (two studies) in the budesonide versus placebo groups. Occurrence of clinically important or serious AEs associated with systemic GCSs, including sepsis, cataracts, adrenal insufficiency was rare and similar between groups.
  
  
  CONCLUSIONS
  Budesonide treatment for up to 1 year is well-tolerated in CD patients, with an AE profile similar to placebo and only rare occurrences of clinically important AEs associated with systemic GCSs.
