The Importance of Monitoring the Postpartum Period in Moderate to Severe Crohn's Disease.

BACKGROUND: Prior research demonstrates Crohn's disease patients often do well in pregnancy; however, less is known about the risk of flare in the postpartum period. METHODS: A retrospective chart review was conducted at a tertiary care inflammatory bowel disease center. All pregnant women with Crohn's disease who were followed in the postpartum period, defined as 6 months after delivery, were included. Statistical analysis included χ 2 analysis, Wilcoxon rank sum test, and logistic regression analysis. The primary outcome of interest was rate of flare in the postpartum period. RESULTS: There were 105 patients included in the study, with a majority (68%) on biologic medication during pregnancy. Thirty-one patients (30%) had a postpartum flare at a median of 9 weeks (range 2-24 weeks). Twenty-five patients (81%) had their postpartum flare managed in the outpatient setting with medications (only 4 of these patients required prednisone). 6 of 31 patients (19%) were hospitalized at a median of 4 weeks (range 2-26 weeks) after delivery, requiring intravenous corticosteroids or surgery. In multivariable regression, there was no significant increase in risk of postpartum flare with increasing maternal age, flare during pregnancy, or steroid or biologic use during pregnancy. Smoking during pregnancy increased risk of postpartum flare (odds ratio, 16.2 [1.72-152.94], P < 0.05). CONCLUSION: In a cohort of Crohn's disease patients, 30% experienced a postpartum flare despite being on medical therapy, but most were able to be managed in the outpatient setting.

A Single Center Experience With Long-Term Ustekinumab Use and Reinduction in Patients With Refractory Crohn Disease.

BACKGROUND: Ustekinumab was approved for moderate and severe Crohn's disease (CD) in 2016, but little is known about long-term outcomes. METHODS: A retrospective study evaluated all patients with CD treated with ustekinumab, including patients with reinduction. C-reactive protein (CRP), Harvey-Bradshaw Index (HBI), Short Inflammatory Bowel Disease (SIBDQ), and endoscopy outcomes were collected prospectively. RESULTS: Ninety-six patients received ustekinumab, resulting in improvement in CRP, HBI, and SIBDQ scores with 68% endoscopic improvement/remission. Thirty-four patients underwent reinduction, resulting in improved HBI and CRP. CONCLUSIONS: Ustekinumab in refractory CD results in significant clinical and endoscopic improvement and reinduction may be a viable option to recapture response.

Risk Factors for Medication Nonadherence to Self-Injectable Biologic Therapy in Adult Patients With Inflammatory Bowel Disease.

BACKGROUND: In inflammatory bowel disease (IBD), including Crohn's disease (CD) and ulcerative colitis (UC), nonadherence to biologic therapy increases risk of disease flare. The aim of this study was to identify risk factors for nonadherence. METHODS: This was a single-center retrospective study evaluating patients with IBD treated at a tertiary care center and prescribed self-injectable biologic therapy using the center's specialty pharmacy. Adherence was defined using medication possession ratio (MPR). Nonadherence was defined as MPR <0.86. RESULTS: Four hundred sixty patients (n = 393 with CD and n = 67 with UC) were evaluated with mean MPR (interquartile range) equaling 0.89 (0.48-1). Overall, 69% of patients were adherent (defined as MPR ≥0.86), 66% of patients with CD and 87% of patients with UC. In univariate analysis, several factors increased risk of nonadherence: CD diagnosis, insurance type, psychiatric history, smoking, prior biologic use, and narcotic use (P < 0.05). In multivariable analysis, Medicaid insurance (odds ratio [OR], 5.5; 95% confidence interval [CI], 1.85-15.6) and CD diagnosis (OR, 2.8; 95% CI, 1.3-6.0) increased risk of nonadherence. In CD, as the number of risk factors increased (narcotic use, psychiatric history, prior biologic use, and smoking), the probability of nonadherence increased. Adherence was 72% in patients with 0-1 risk factors, decreasing to 62%, 61%, and 42% in patients with 2, 3, and 4 risk factors, respectively (P < 0.05). CONCLUSIONS: This study identified risk factors for nonadherence to biologic therapy. In patients with CD, the probability of nonadherence increased as the number of risk factors increased.

Treatment with immunosuppressive therapy may improve depressive symptoms in patients with inflammatory bowel disease.

INTRODUCTION: Recent research suggests a relationship of inflammatory bowel disease (IBD) and depression. Our objective was to evaluate for improvement of depressive symptoms with treatment of IBD using immunosuppressive medications. METHODS: A retrospective study of consecutive patients with IBD started on immunosuppressive agents [anti-tumor necrosis factor (anti-TNF) or immunomodulator therapy] was conducted. Patients were evaluated if disease activity indices using Harvey Bradshaw Index for Crohn's disease (CD) and Simple Clinical Colitis Disease Activity Index for ulcerative colitis (UC) and depressive indices using Patient Health Questionnaire-9 (PHQ-9) scores were obtained before and at least 30 days after initiation of therapy. RESULTS: Sixteen patients with UC and 53 patients with CD (all with active disease symptoms) were evaluated over a 60 day median follow-up evaluation (range 30, 140 days). Twenty-two patients started on immunomodulator therapy, and 47 patients started on anti-TNF therapy. Crohn's disease patients had significantly decreased PHQ-9 scores at follow-up [median 9 (range 3, 14) to 4 (1, 8)], with significant decreases only in those started on anti-TNF therapy. Changes in PHQ-9 and CRP were correlated (ρ = 0.38, p < 0.05). In patients with UC, PHQ-9 scores [5 (3, 9) to 2 (0, 5)] were significantly decreased. Percentage at risk of moderate to severe depression (PHQ-9 scores ≥10) was lower after treatment [Crohn's disease 51-18 % (p < 0.05), ulcerative colitis 18-0 %]. CONCLUSION: Depressive scores decreased significantly in patients with IBD treated with immunosuppressive therapy and the number at risk for moderate to severe depression improved significantly.

Survey of gastroenterologists' awareness and implementation of AGA guidelines on osteoporosis in inflammatory bowel disease patients: are the guidelines being used and what are the barriers to their use?

BACKGROUND: The American Gastroenterology Association (AGA) published guidelines to assist clinicians in the evaluation and management of osteoporosis in inflammatory bowel disease (IBD) patients. Two studies suggest that when clinicians utilized the guidelines, the majority of their IBD patients were appropriately screened and treated for metabolic bone disease. The aim was to study whether physicians who say they use the AGA Guidelines are, in fact, following the recommendations, and to assess the barriers preventing the use of the guidelines in the management of osteoporosis in their IBD patients. METHODS: In all, 1000 physicians were selected from the AGA membership list and mailed a survey inquiring into awareness and implementation of the guidelines on osteoporosis in IBD patients. The barriers to implementation of the guidelines were also assessed. The sum of 21 self-reported clinical practices (absence = 0, presence = 1) was used to evaluate adherence to the guidelines. A value of 0 implied no adherence while a score of 21 meant complete adherence. RESULTS: Of 304 responders, 27 fellows, 8 retirees, and 11 incomplete responses were not included in the analysis; thus, 258 respondents were the subject of this analysis. Slightly less than half of the responders used the guidelines in decision-making (126, 49%) or in the management (110, 42%) of their IBD patients. Using the scoring system described above, clinicians self-reporting use of the guidelines had a significantly higher clinical practice score than those who did not use the guidelines (Wilcoxon rank sum test; P < 0.0001). Only 18% (12 of 68) of clinicians whose practice was comprised of 25%) were also more likely (97/187 = 52%) to assess and treat osteoporosis in their IBD patients. Conversely, only 16% (11/68) of physicians who saw
