The relationship of major depressive disorder with Crohn?s disease activity

Introduction: Crohn's disease (CD) has been related to an increased prevalence of psychiatric disorders and suicide risk (SR). However, the nature of their relationship still deserves clarification. The aim of this study is to assess the prevalence of major depressive disorder (MDD) in patients with CD, and to investigate the relationship between MDD and CD outcomes.Methods: A cross-sectional study involving CD patients was performed. CD activity was evaluated by the Harvey -Bradshaw index and CD phenotype by the Montreal classification. The presence of MDD was assessed by the Patient Health Questionnaire score-9 (PHQ-9). Sociodemographic data and other characteristics were retrieved from electronic medical records.Results: 283 patients with CD were included. The prevalence of MDD was 41.7%. Females had a risk of MDD 5.3 times greater than males. CD disease duration was inversely correlated with MDD severity. Individuals with active CD were more likely to have MDD (OR = 796.0; 95% CI 133.7-4738.8) than individuals with CD remis-sion. MDD was more prevalent in inflammatory behavior (45.5%) and there were no statistical differences regard-ing the disease location. 19.8% of the sample scored positive for SR.Conclusion: The present results support data showing an increased prevalence of MDD in individuals with CD. Additionally, it indicates that MDD in CD might be related to the activity of CD. Prospective studies are warranted to confirm these results and to address whether MDD leads to CD activity, CD activity leads to MDD or both ways are existent.

Automated summary

This study aims to assess the prevalence of major depressive disorder (MDD) in patients with Crohn's disease (CD) and examine the relationship between MDD and CD outcomes. The findings showed a high prevalence of MDD in CD patients and suggested a potential association between MDD and CD activity.
