title: [Factors influencing the decision to administer systemic corticosteroids in Crohn's disease].
abstract: BACKGROUND
  Crohn's disease shows periods of exacerbation and remission. Corticosteroids are the most frequently used drugs in exacerbations of disease activity. The objective of this study is to determine which clinical and laboratory parameters are associated with the therapeutic decision to administer corticosteroids during the course of the disease.
  
  
  METHODS
  Two-hundred seven consecutive visits made by 62 patients with Crohn's disease were selected from a database. Data from visits in which corticosteroid administration was initiated (n = 65) were compared with those from visits in which this decision was not made (n = 142). Univariate and multivariate (logistic regression) analyses were performed. The results are expressed as odds ratio (OR) with 95% confidence interval (95% CI).
  
  
  RESULTS
  In the univariate analysis statistically significant differences were found between groups in localization, maintenance treatment, Crohn's Disease Activity Index (CDAI) score, the presence of abdominal pain, mass, perianal disease, extraintestinal manifestations and all laboratory parameters (leukocytes, platelets, fibrinogen, erythrocyte sedimentation rate, C-reactive protein). In the multivariate analysis (with corticosteroid administration as the dependent variable) a statistically significant positive association was found between the decision to administer corticosteroids and mild (OR = 31.9; 95% CI, 6.6-154.1), moderate or severe (OR = 49.7; 95% CI, 6.1-401.3) CDAI, ileocolic localization (OR = 4.8; 95% CI, 1-22.1) and the presence of perianal disease (OR = 7.4; 95% CI, 1.5-35.9), while a negative association was found with maintenance treatment with immunosuppressant drugs (OR = 0.05; 95% CI, 0.30-0.008). The laboratory variables positively associated with corticosteroid administration were C-reactive protein and leukocyte count.
  
  
  CONCLUSIONS
  The variable with greatest predictive value for corticosteroid prescription is the CDAI score, although other clinical and laboratory variables not included in this index are also associated with corticosteroid administration. There is a negative association between the use of immunosuppressive drugs and corticosteroid prescription.
