Background: Abdominal pain and opioid analgesic use are common in Crohn's disease (CD)., Aims: We sought to identify factors associated with abdominal pain in CD and evaluate the impact of opioid analgesics on pain and quality-of-life scores in this setting., Methods: We performed a longitudinal cohort study using a prospective, consented IBD natural history registry from a single academic center between 2009 and 2013. Consecutive CD patients were followed for at least 1 year after an index visit. Data were abstracted regarding pain experience (from validated surveys), inflammatory activity (using endoscopic/histologic findings), laboratory studies, coexistent psychiatric disorders, medical therapy, opioid analgesic, and tobacco use., Results: Of 542 CD patients (56.6% women), 232 (42.8%) described abdominal pain. Individuals with pain were more likely to undergo surgery and were more frequently prescribed analgesics and/or antidepressants/anxiolytics. Elevated ESR (OR 1.79; 95%CI 1.11-2.87), coexistent anxiety/depression (OR 1.87; 95%CI 1.13-3.09), smoking (OR 2.08; 95%CI 1.27-3.40), and opioid use (OR 2.46; 95%CI 1.33-4.57) were independently associated with abdominal pain. Eighty patients (14.8%) were prescribed opioids, while 31 began taking them at or after the index visit. Patients started on opioids demonstrated no improvement in abdominal pain or quality-of-life scores on follow-up compared to patients not taking opioids., Conclusions: Abdominal pain is common in CD and is associated with significant opioid analgesic utilization and increased incidence of anxiety/depression, smoking, and elevated inflammatory markers. Importantly, opioid use in CD was not associated with improvement in pain or quality-of-life scores. These findings reinforce the limitations of currently available analgesics in IBD and support exploration of alternative therapies.

Background: Diseases of immune dysregulation are associated with an increased risk of viral infections, some of which may be preventable. To date, there are very limited data on the incidence and risk of influenza and related complications in patients with inflammatory bowel disease (IBD). Furthermore, the impact of immunosuppressive medications on that risk is unclear. Therefore, the aim of this study was to estimate the incidence and severity of influenza infections in IBD patients. In addition, we looked specifically at the effect of medications on influenza risk., Methods: Using the MarketScan Database (January 2008 to December 2011), we conducted a retrospective cohort study to estimate the incidence of influenza and risk of related complications in IBD patients compared with those without IBD. We employed a nested case-control study design to evaluate the potential independent effect of IBD medications on influenza risk., Results: A total of 140,480 patients with IBD and non-IBD controls were studied. There were 2963 patients with influenza compared with 1941 non-IBD subjects. Inflammatory bowel disease patients had an increased influenza risk compared with those without IBD (incidence rate ratio, 1.54; 95% confidence interval [CI], 1.49-1.63). A higher rate of hospitalizations (162/2994 [5.4%] vs 36/1941 [1.85%]; P < 0.001) was noted. Systemic corticosteroids were found to be independently associated with influenza (odds ratio, 1.22; 95% CI, 1.08-1.38)., Conclusions: Inflammatory bowel disease patients had an increased risk of influenza compared with those without IBD and were more likely to require hospitalization. Steroids were the only medication class independently associated with flu risk.

Background: Individuals with inflammatory bowel disease (IBD) are at increased risk of developing anxiety or depression (A&D). Crohn's disease (CD) and ulcerative colitis (UC) with comorbid A&D are both more challenging to manage. IBD providers need to better understand the causes and impact of A&D in order to improve care for IBD patients. We sought to identify clinical factors that influence development of A&D and healthcare utilization in IBD., Methods: This is a retrospective analysis using an IBD natural history registry from a single tertiary care referral center. Presence of A&D was determined based upon responses to the Hospital Anxiety and Depression Scale. Demographic and clinical factors were abstracted to evaluate for significant associations., Results: Four hundred thirty-two IBD patients (132 UC, 256 CD, and 44 indeterminate colitis) were included in this study. One hundred ninety-two (44.4%) had anxiety or depression or both, and most were female (59.4%, P < 0.05). History of surgery (P < 0.05), female gender (P < 0.05), smoking (P < 0.05), and extra-intestinal manifestations (P < 0.01) were each independently predictive of A&D. Inflammatory bowel disease patients with A&D more often underwent imaging studies (53.6% vs 36.7%, P < 0.05), visited the ED (30.7% vs 20.8%, P < 0.05), or were hospitalized (31.7% vs 21.7%, P < 0.05). They were also more frequently prescribed corticosteroids (50.5% vs 36.7%, P < 0.01) and biologic medications (62.5% vs 51.3%, P < 0.05). Finally, they were more likely to have had at least 1 "no-show" (29.2% vs 16.7%, P < 0.01) and had a higher mean number of "no-shows" (0.69 +/- 0.1 vs 0.30 +/- 0.1, P < 0.01) over the study period., Discussion: Anxiety and depression are common in the setting of IBD and are strongly associated with surgical history, disease complications (including extra-intestinal manifestations), smoking, and female gender. Inflammatory bowel disease patients with A&D are also more likely to require therapy and to utilize healthcare resources. This study refines our understanding of A&D development and its impact in IBD and provides additional considerations for management in this setting.
