BACKGROUND AND AIMS: Recent studies demonstrated that depression was associated with mucosal inflammation in patients with ulcerative colitis (UC). This association had not been studied in patients with UC with ileal pouch-anal anastomosis (IPAA) after restorative proctocolectomy. We hypothesized that depression and mucosal proinflammatory cytokines in UC-patients with pouchitis were associated. METHODS: We assessed 18 IPAA-UC-patients with pouchitis and 19 IPAA-UC-patients without pouchitis. Mucosal biopsies were taken from the areas with maximal inflammation in the pouch or from the posterior wall of the pouch if the pouch had a normal endoscopic appearance. Disease activity was assessed by the Pouch Disease Activity Index. The expression of mucosal proinflammatory gene transcripts (interleukin-8 [IL-8] and interleukin-1ß [IL-1b]) was quantified by real-time polymerase chain reaction. Depression was assessed by the Hospital Anxiety and Depression Scale (HADS). Pearson correlations between depression and cytokine transcripts were calculated. RESULTS: The correlation of HADS depression scores of patients with pouchitis with IL-8 was r=0.51 (p=0.03) and with IL-1ß was r=0.47 (p=0.04). The correlation between the HADS depression scores of patients without pouchitis with IL-8 was r=-0.19; (p=0.21) and with IL-1ß was r=-0.12 (p=0.30). CONCLUSION: Depression is associated with mucosal proinflammatory cytokines in patients with pouchitis after restorative proctocolectomy in patients with UC.
