    Background

    It is unknown if the clinical manifestations and phenotype of disease are comparable between early- and elderly-onset inflammatory bowel disease (IBD). We aimed to seek differences in disease phenotype, course, complications, and treatment between early- and elderly-onset IBD patients.

    Methods

    This retrospective cohort study on registered IBD patients in the Iranian Registry of Crohn’s and Colitis (IRCC) compared demographics, disease phenotype, disease activity, IBD-related surgery and medications between early- and elderly-onset IBD. A generalized linear regression model was used to investigate the relative risk of age at diagnosis adjusted for gender and disease duration for the outcomes.

    Results

    From 10 048 IBD patients, 749 with early-onset (7.5%), and 472 (4.7%) elderly-onset IBD were enrolled: 855 (63.1%) ulcerative colitis (UC) and 366 (26.9%) Crohn’s disease (CD). Left-sided colitis was more frequent among elderly-onset UC patients (P < 0.001). Ileum and ileocolonic locations were the most common types in elderly-onset and early-onset CD patients, respectively. In comparison with elderly-onset UC, early-onset cases more often used prednisolone (22.1% vs. 11.4%, P = 0.001), immunomodulators (44.9% vs 25.2%, P < 0.001) and anti-tumor necrosis factors (TNF) (20.1% vs 11.9%, P = 0.002). Elderly-onset UC patients had 0.7 times lower risk of aggressive phenotype (95%CI:0.6‒0.9, P = 0.005). Early-onset CD was associated with higher use of prednisolone (27.7% vs 8.1%, P < 0.001), immunomodulators (58.7% vs 41.8%, P = 0.005) and anti-TNF (49.6% vs 35.4%, P = 0.006).

    Conclusion

    Early-onset IBD was associated with a more aggressive phenotype and higher prednisolone, immunomodulators, and anti-TNF use.

    BACKGROUND

    Immunosuppressive agents used in the treatment of inflammatory bowel diseases (IBDs) could potentially increase the risk of coronavirus disease 2019 (COVID-19). We aimed to compare COVID-19 frequency in patients with IBD with their households and identify the related risk factors.

    METHODS

    Firstly, a multi-centered, observational study on 2110 patients with IBD and 2110 age-matched household members was conducted to compare COVID-19 frequency. Secondly, the data of patients with IBD and COVID-19 who had called the COVID-19 hotline were added. Multivariable logistic regression was used to evaluate the effect of age, type and severity of IBD, the number of comorbidities, and medications on the frequency of COVID-19 among the patients with IBD.

    RESULTS

    The prevalence of COVID-19 in patients with IBD and household groups was similar (34 [1.61%] versus 35 [1.65%]; P = 0.995). The prevalence of COVID-19 increased from 2.1% to 7.1% in those with three or more comorbidities (P = 0.015) and it was significantly higher in those with severe IBD (P = 0.026). The multivariable analysis only showed a significant association with anti-TNF monotherapy (OR: 2.5, CI: 0.97-6.71, P = 0.05), and other medications were not associated with COVID-19.

    CONCLUSION

    The prevalence of COVID-19 in patients with IBD was similar to the household members. Only patients with IBD receiving anti-TNF monotherapy had a higher risk of COVID-19 susceptibility. This finding could be attributed to the higher exposure to the virus during administration in health care facilities.

    Background

     Most data on the effect of inflammatory bowel disease (IBD) and its treatments on coronavirus disease 2019 (COVID-19) outcomes have not had non-IBD comparators. Hence, we aimed to describe COVID-19 outcomes in IBD compared to non-IBD patients.

    Methods

     We conducted a prospective cohort study of registered IBD patients with confirmed COVID-19 from six provinces in Iran from February to April 2020. Proven COVID-19 patients were followed up at four weeks and the frequency of outcomes was assessed. Multivariable logistic regression was used to assess associations between demographics, clinical characteristics and COVID-19 outcomes.

    Results

     Overall, 2159 IBD patients and 4721 household members were enrolled, with 84 (3.9%) and 49 (1.1%) participants having confirmed COVID-19, respectively. Household spread of COVID-19 was not common in this cohort (1.2%). While hospitalization was significantly more frequent in IBD patients compared with non-IBD household members (27.1% vs. 6.0%, P=0.002), there was no significant difference in the frequency of severe cases. Age and presence of IBD were positively associated with hospitalization in IBD compared with non-IBD household members (OR: 1.06, 95% CI: 1.03-1.10; OR: 5.7, 95% CI: 2.02– 16.07, respectively). Age, presence of new gastrointestinal symptoms, and 5-aminosalicylic acid (5-ASA) use were associated with higher hospitalization rate in IBD patients (OR: 1.13, 95% CI: 1.05–1.23; OR: 6.49, 95% CI: 1.87–22.54; OR: 6.22, 95% CI: 1.90–20.36, respectively). Anti-tumor necrosis factor (TNF) was not associated with more severe outcomes.

    Conclusion

     Age, presence of new gastrointestinal symptoms and use of 5-ASA were associated with increased hospitalization rate among IBD patients, while anti-TNF therapy had no statistical association.

    BACKGROUND The COVID-19 pandemic has affected the health care infrastructure dramatically, with abundant resources necessarily being redirected to COVID-19 patients and their care. Also, patients with chronic diseases like inflammatory bowel disease (IBD) may be affected in several ways during this pandemic. METHODS We used the Iranian registry of Crohn’s and colitis (IRCC) infrastructure. We called and sent messages to follow-up and support the care of all registered patients. Besides, we prepared and distributed educational materials for these patients and physicians to reduce the risk of COVID-19 infection. We risk-stratified them and prepared outpatient clinics and hospitalization guidance for IBD patients. RESULTS Of 13165 Iranian patients with IBD, 51 have been diagnosed as having COVID-19. IBD patients made 1920 hotline calls. Among the patients with suspicious presentations, 14 COVID-19 infections were diagnosed. Additionally, 1782 patients with IBD from five provinces actively phone-called among whom 28 definite cases were diagnosed. CONCLUSION IBD patients’ follow-up could help in diagnosing the affected IBD patients with COVID-19. Additionally, the performance of protective actions and preparing the patients and physicians for decisive proceedings are the principles of protection of IBD patients.

    BACKGROUND

     The anti-TNF drugs are shown to be highly effective in treatment of patients with moderate-tosevere inflammatory bowel disease (IBD). Here, we aimed to assess the efficacy and safety of antiTNF therapy at the national level.

    METHODS

     IBD patients aged 15 > years who received Infliximab and/or CinnoRA® between 2013 to July 2018 were identified. The data extracted from medical dossier and telephonic interview. The efficacy of therapy was defined as time to drug discontinuation or need for IBD-related surgery. The safety was assessed based on patient’s reported adverse events.

    RESULTS

     We included 315 patients. The mean age of patients was 37.2 years and 62.2% of them developed the disease before age 30 years. Involvement of masculoskeletal system was reported in 7.3% of patients. Partial and complete response to Anti-TNF therapy was seen in 67% of patients. About 16% of patients did not respond to induction therapy and 16.9% of patients lost their response to Anti-TNF during one year. No serious adverse events, serious opportunistic infection, tuberculosis and malignancies reported by patients. Two patients reported pneumonia.

    CONCLUSION

    This study for the first time in our country, provides the evidences for efficacy of anti-TNF therapy in moderate to severe IBD patients.

    Introduction
    Administrators require reliable, valid, and practical methods for evaluating the quality of medical education in each department especially for clerkship which is likely to be neglected. This study presents a periodic systematic questionnaire survey of medical students as an administrative tool for evaluation of clerkship education quality.
    Methods
    A 16 questions questionnaire was designed based on World Federation of Medical Education (WFME) global standards, considering student’s educational satisfaction of a hospital department. After assessment of validity and reliability (total score = 80), the questionnaires were completed by all 2771 medical students taking courses in different departments of a tertiary hospital affiliated to Tehran University of Medical Sciences (2007-2012) . Periodic feedbacks were provided to clerkship program directors based on the survey results.
    Result
    Our study showed Medical Student's Systematic Feedback made departments improve their program and led to significant changes in mean scores of student satisfaction from 47.9 ±16.5 to 57.4±15.6 (P
    Conclusion
    Periodic systematic feedback system is a feasible method for continuous evaluation of clerkship programs and can lead to improvement of educational performance of teaching hospitals.
