ABSTRACT
Background: Individuals with inflammatory bowel disease (IBD) are up to twice as likely to suffer from anxiety and/or depression. Collaborative care management (CoCM) is an evidence-based approach to treating behavioral health disorders that have proven effective for a range of conditions in primary care and some specialty settings. This model involves a team-based approach, with care delivered by a care manager (case reviews and behavioral therapy), psychiatrist (case reviews and psychopharmacological recommendations), and medical provider (ongoing care including psychopharmacological prescriptions). We assessed the feasibility and effectiveness of CoCM in reducing anxiety and depressive symptoms in patients with IBD. Methods: Patients with psychological distress identified by clinical impression and/or the results of the Patient Health Questionaire-9 (PHQ-9) and Generalized Anxiety Disorder-7 (GAD-7) were referred to the CoCM program. Data from our 9-month CoCM pilot were collected to assess depression and anxiety response and remission rates. We obtained provider surveys to assess provider acceptability with delivering care in this model. Results: Though the SARS-CoV2 COVID-19 pandemic interrupted screening, 39 patients enrolled and 19 active participants completed the program. Overall, 47.4% had either a response or remission in depression, while 36.8% had response or remission in anxiety. The gastroenterologists highly agreed that the program was a beneficial resource for their patients and felt comfortable implementing the recommendations. Discussion: CoCM is a potentially feasible and well accepted care delivery model for treatment of depression and anxiety in patients with IBD in a specialty gastroenterology clinic setting.
ABSTRACT
The host receptor for SARS-CoV-2, angiotensin-converting enzyme 2 (ACE2), is highly expressed in small intestine. Our aim was to study colonic ACE2 expression in Crohn's disease (CD) and non-inflammatory bowel disease (non-IBD) controls. We hypothesized that the colonic expression levels of ACE2 impacts CD course. We examined the expression of colonic ACE2 in 67 adult CD and 14 NIBD control patients using RNA-seq and quantitative (q) RT-PCR. We validated ACE2 protein expression and localization in formalin-fixed, paraffin-embedded matched colon and ileal tissues using immunohistochemistry. The impact of increased ACE2 expression in CD for the risk of surgery was evaluated by a multivariate regression analysis and a Kaplan-Meier estimator. To provide critical support for the generality of our findings, we analyzed previously published RNA-seq data from two large independent cohorts of CD patients. Colonic ACE2 expression was significantly higher in a subset of adult CD patients which was defined as the ACE2-high CD subset. IHC in a sampling of ACE2-high CD patients confirmed high ACE2 protein expression in the colon and ileum compared to ACE2-low CD and NIBD patients. Notably, we found that ACE2-high CD patients are significantly more likely to undergo surgery within 5 years of CD diagnosis, and a Cox regression analysis found that high ACE2 levels is an independent risk factor for surgery (OR 2.17; 95% CI, 1.10-4.26; p = 0.025). Increased intestinal expression of ACE2 is associated with deteriorated clinical outcomes in CD patients. These data point to the need for molecular stratification that can impact CD disease-related outcomes.
