Antibiotic Use in the 12 Months Prior to Ileal Pouch-Anal Anastomosis Increases the Risk for Pouchitis.

BACKGROUND & AIMS: Pouchitis is the most common complication after ileal pouch-anal anastomosis (IPAA) for ulcerative colitis (UC); however, clinical and environmental risk factors for pouchitis remain poorly understood. We explored the relationship between specific clinical factors and the incidence of pouchitis. METHODS: We established a population-based cohort of all adult persons in Denmark undergoing proctocolectomy with IPAA for UC from 1996-2020. We used Cox proportional hazard modeling to assess the impact of antibiotic, nonsteroidal anti-inflammatory drug (NSAID) exposure, and appendectomy on diagnosis of acute pouchitis in the first 2 years after IPAA surgery. RESULTS: Among 1616 eligible patients, 46% developed pouchitis in the first 2 years after IPAA. Antibiotic exposure in the 12 months before IPAA was associated with an increased risk of pouchitis (adjusted hazard ratio [aHR], 1.41; 95% confidence interval [CI], 1.22-1.64) after adjusting for anti-tumor necrosis factor alpha use and sex. Compared with persons without any antibiotic prescriptions in the 12 months before IPAA, the risk of pouchitis was increased in those with 1 or 2 courses of antibiotics in that period (aHR, 1.30; 95% CI, 1.11-1.52) and 3 or more courses (aHR, 1.77; 95% CI, 1.41-2.21). NSAID exposure in the 12 months before IPAA and appendectomy were not associated with risk of acute pouchitis (P = .201 and P = .865, respectively). CONCLUSIONS: In this population-based cohort study, we demonstrated that antibiotic exposure in the 12 months before IPAA is associated with an increased risk of acute pouchitis. Future prospective studies may isolate specific microbial changes in at-risk patients to drive earlier interventions.

Medication-Wide Study: Exploring Medication Use 10 Years Before a Diagnosis of Inflammatory Bowel Disease.

INTRODUCTION: There is growing interest in the prediagnostic phase of inflammatory bowel disease (IBD) and in the overlap of IBD with other diseases. We described and compared use of any prescription medication between individuals with and without IBD in a 10-year period preceding diagnosis. METHODS: Based on cross-linked nationwide registers, we identified 29,219 individuals diagnosed with IBD in Denmark between 2005 and 2018 and matched to 292,190 IBD-free individuals. The primary outcome was use of any prescription medication in years 1-10 before IBD diagnosis/matching date. Participants were considered as medication users if they redeemed ≥1 prescription for any medication in the World Health Organization Anatomical Therapeutic Chemical (ATC) main groups or subgroups before diagnosis/matching. RESULTS: The IBD population had a universally increased use of medications compared with the matched population before IBD diagnosis. At 10 years before diagnosis, the proportion of users was 1.1-fold to 1.8-fold higher in the IBD population in 12 of 14 ATC main groups of medication ( P -value < 0.0001). This applied across age, sex, and IBD subtypes, although it was the most pronounced for Crohn's disease (CD). Two years before diagnosis, the IBD population had a steep increase in medication use for several organ systems. When analyzing therapeutic subgroups of medication, the CD population exhibited 2.7, 2.3, 1.9, and 1.9 times more users of immunosuppressants, antianemic preparations, analgesics, and psycholeptics, respectively, than the matched population 10 years before diagnosis ( P -value < 0.0001). DISCUSSION: Our findings demonstrate universally increased medication use years before IBD, especially CD, diagnosis and indicates multiorgan involvement in IBD.

Has the Incidence of Inflammatory Bowel Disease Peaked? Evidence From the Population-Based NorDIBD Cohort 1978-2020.

INTRODUCTION: While the incidence of inflammatory bowel disease (IBD) is rising globally, it has been suggested to stabilize in westernized countries, but this has not yet been shown in exhaustive and large cohorts. We generated an IBD cohort in North Denmark (NorDIBD) of 6,158 patients with IBD diagnosed from 1978 to 2020, based on all recorded and verified IBD diagnoses in the region. While describing the establishment of this cohort, we aimed to present the accurate incidence and prevalence of IBD over 4 decades. METHODS: The NorDIBD cohort covered all pediatric and adult patients with an IBD diagnosis dated between January 1, 1978, and December 31, 2020, and living in North Denmark, hence forming an unselected population-based patient cohort. IBD incidence rates between 1978 and 2020 and IBD point prevalences between 2003 and 2020 were calculated. RESULTS: We observed a 4-fold increase in the incidence of IBD from 11.5 per 100,000 persons (95% confidence interval [CI] 8.4-14.6) in the year 1978 to 51.3/100,000 (95% CI 45.5-57.1) in the year 2014, whereas in 2020, this rate stabilized. The overall prevalence of IBD more than doubled from 2003 to 2020, from 424 (95% CI 407-443) in 2003 to 872 (95% CI 849-896) IBD cases per 100,000 persons in 2020. DISCUSSION: Our population-based NorDIBD cohort suggests stabilizing of the incidence of IBD in Denmark, whereas the prevalence continues to rise. Because the data represent a 10% sample of the entire Danish IBD population, we believe that data can be extrapolated to the IBD population in general and used for healthcare planning.

Increased risk of obstructive lung disease in inflammatory bowel disease: A population-based cohort study.

BACKGROUND AND AIMS: Inflammatory bowel disease (IBD) is associated with disease manifestations in organs other than the gastrointestinal tract. In this study, we aimed to estimate the odds of obstructive lung disease (OLD) before IBD onset and the risk of OLD after IBD onset. METHODS: In a nationwide population-based Danish cohort study from 1999 to 2018, individuals with IBD and OLD were identified using the Danish registries. Between 2003 and 2013, 24,238 individuals with IBD were identified and matched 1:10 with non-IBD individuals. Logistic regression was used to estimate the prevalence odds ratio for OLD before IBD onset. Time-to-event analysis was performed to explore the risk of OLD after IBD onset. In a sensitivity analysis, the time-to-event analysis was repeated using the composite outcome OLD and the separate outcomes, chronic obstructive pulmonary disease (COPD), asthma, and bronchiectasis. RESULTS: Individuals with IBD were 60% more likely to have OLD before onset (adjusted odds ratio: 1.60, 95% confidence interval [CI]: 1.53-1.67). Furthermore, their risk of OLD was more than 40% higher after IBD diagnosis (adjusted hazard ratio [aHR]: 1.43, 95% CI: 1.37-1.49). The sensitivity analysis increased the risk to 60% (aHR: 1.63, 95% CI: 1.53-1.73). Similar results were found for COPD and asthma separately, whereas the risk of bronchiectasis increased more than 2-fold (aHR: 2.44, 95% CI: 1.91-3.11). CONCLUSION: The odds of OLD before- and the risk following an IBD diagnosis were increased. We encourage physicians to be vigilant of pulmonary symptoms in persons with IBD and gastrointestinal symptoms in individuals with OLD.

Clinical and cost-effectiveness of vaginal pessary self-management compared to clinic-based care for pelvic organ prolapse: protocol for the TOPSY randomised controlled trial.

BACKGROUND: Pelvic organ prolapse (or prolapse) is a common condition in women where the pelvic organs (bladder, bowel or womb) descend into the vagina and cause distressing symptoms that adversely affect quality of life. Many women will use a vaginal pessary to treat their prolapse symptoms. Clinic-based care usually consists of having a pessary fitted in a primary or secondary care setting, and returning approximately every 6 months for healthcare professional review and pessary change. However, it is possible that women could remove, clean and re-insert their pessary themselves; this is called self-management. This trial aims to assess if self-management of a vaginal pessary is associated with better quality of life for women with prolapse when compared to clinic-based care. METHODS: This is a multicentre randomised controlled trial in at least 17 UK centres. The intervention group will receive pessary self-management teaching, a self-management information leaflet, a follow-up phone call and access to a local telephone number for clinical support. The control group will receive the clinic-based pessary care which is standard at their centre. Demographic and medical history data will be collected from both groups at baseline. The primary outcome is condition-specific quality of life at 18 months' post-randomisation. Several secondary outcomes will also be assessed using participant-completed questionnaires. Questionnaires will be administered at baseline, 6, 12 and 18 months' post-randomisation. An economic evaluation will be carried out alongside the trial to evaluate cost-effectiveness. A process evaluation will run parallel to the trial, the protocol for which is reported in a companion paper. DISCUSSION: The results of the trial will provide robust evidence of the effectiveness of pessary self-management compared to clinic-based care in terms of improving women's quality of life, and of its cost-effectiveness.
