The Association of Medications and Vaccination with Risk of Pneumonia in Inflammatory Bowel Disease

Abstract Background Patients with inflammatory bowel disease (IBD) are at increased risk for pneumonia, and corticosteroids are reported to amplify this risk. Less is known about the impact of corticosteroid-sparing IBD therapies on pneumonia risk or the efficacy of pneumococcal vaccination in reducing all-cause pneumonia in real-world IBD cohorts. Methods We performed a population-based study using an established Veterans Health Administration cohort of 29,957 IBD patients. We identified all patients who developed bacterial pneumonia. Cox survival analysis was used to determine the association of corticosteroids at study entry and as a time-varying covariate, corticosteroid-sparing agents (immunomodulators and antitumor necrosis-alpha [TNF] inhibitors), and pneumococcal vaccination with the development of all-cause pneumonia. Results Patients with IBD who received corticosteroids had a greater risk of pneumonia when controlling for age, gender, and comorbidities (hazard ratio [HR] 2.21; 95% confidence interval [CI], 1.90–2.57 for prior use; HR = 3.42; 95% CI, 2.92–4.01 for use during follow-up). Anti-TNF inhibitors (HR 1.52; 95% CI, 1.02–2.26), but not immunomodulators (HR 0.91; 95% CI, 0.77–1.07), were associated with a small increase in pneumonia. A history of pneumonia was strongly associated with subsequent pneumonia (HR = 4.41; 95% CI, 3.70–5.27). Less than 15% of patients were vaccinated against pneumococcus, and this was not associated with a reduced risk of pneumonia (HR = 1.02; 95% CI, 0.80–1.30) in this cohort. Conclusion In a large US cohort, corticosteroids were confirmed to increase pneumonia risk. Tumor necrosis-alpha inhibitors were associated with a smaller increase in the risk of pneumonia. Surprisingly, pneumococcal vaccination did not reduce all-cause pneumonia in this population, though few patients were vaccinated.

The Impact

Abstract Background Streptococcus pneumoniae is an important pathogen responsible for severe pneumococcal diseases, including pneumonia, bacteremia/sepsis, and meningitis. Inflammatory bowel disease (IBD) patients have an increased risk for infections due to an altered immune system and treatment with immunosuppressive medications. The aim of this study was to assess the prevalence of severe pneumococcal disease (SPD) and evaluate the impact of pneumococcal vaccination on the risk of SPD in Veterans with IBD. Methods Subjects with IBD and SPD were identified from the VA Health Administration database using ICD9/10 codes. Pneumococcal vaccination and use of immunosuppressant medications were collected. Risk of SPD was evaluated using an adjusted Cox proportional hazards model controlling for demographics, medications, vaccination, and comorbidities. Results A total of 1798 cases of SPD were identified (283 pneumonia, 1,513 bacteremia, and 2 meningitis). SPD patients were older (60.9 years vs 59.4 years; p<0.001), had more comorbidities (Charlson Comorbidity Index of 2.11 vs. 0.96; p<0.001) and had increased mortality (4.6% vs. 1.5%, p<0.001). The risk of SPD was increased in Crohn’s disease (HR 1.15; 95% CI 1.05-1.27) and with more comorbidities (HR 1.45; 95% CI 1.42-1.48). Use of immunosuppressive medications increased the risk of SPD. Receipt of PCV13 either alone or in combination with PPSV23 predicted a five-fold decreased risk of SPD compared with no vaccination. Conclusion Vaccination with PCV13 alone or in combination with PPSV23 and revaccination with PPSV23, was protective against SPD. All IBD patients should be evaluated for pneumococcal vaccination, particularly those receiving or expected to receive immunosuppressive therapies.

The Impact

The role of early-life environmental exposures on Inflammatory Bowel Disease (IBD) onset remains unclear. We aimed to quantify the impact of perinatal conditions and antibiotic use in the first 6 and 12 months of life, on the risk of childhood-onset IBD, in a birth cohort of the region Friuli-Venezia Giulia (Italy). A nested case-control design on a longitudinal cohort of 213,515 newborns was adopted. Conditional binomial regression models were used to estimate Odds Ratios (OR) with 95% confidence intervals (CI) for all analyzed risk factors. We identified 164 individuals with IBD onset before the age of 18 years and 1640 controls. None of the considered perinatal conditions were associated with IBD. Analyses on antibiotic exposure were based on 70 cases and 700 controls. Risks were significantly higher for children with ≥4 antibiotic prescriptions in the first 6 and 12 months of life (OR = 6.34; 95%CI 1.68–24.02 and OR = 2.91; 95%CI 1.31–6.45, respectively). This association was present only among patients with Crohn’s disease and those with earlier IBD onset. We found that perinatal characteristics were not associated to IBD, while the frequent use of antibiotics during the first year of life was associated to an increased risk of developing subsequent childhood-onset IBD.

ObjectivePatients with inflammatory bowel disease (IBD) have an elevated risk of mental illness. We determined the incidence and correlates of new-onset mental illness associated with IBD during pregnancy and post partum.DesignThis cohort study using population-based health administrative data included all women with a singleton live birth in Ontario, Canada (2002–2014). The incidence of new-onset mental illness from conception to 1-year post partum was compared between 3721 women with and 798 908 without IBD, generating adjusted HRs (aHR). Logistic regression was used to identify correlates of new-onset mental illness in the IBD group.ResultsAbout 22.7% of women with IBD had new-onset mental illness versus 20.4% without, corresponding to incidence rates of 150.2 and 132.8 per 1000 patient-years (aHR 1.12, 95% CI 1.05 to 1.20), or one extra case of new-onset mental illness per 43 pregnant women with IBD. The risk was elevated in the post partum (aHR 1.20, 95% CI 1.09 to 1.31), but not during pregnancy, and for Crohn’s disease (aHR 1.12, 95% CI 1.02 to 1.23), but not ulcerative colitis. The risk was specifically elevated for a new-onset mood or anxiety disorder (aHR 1.14, 95% CI 1.04 to 1.26) and alcohol or substance use disorders (aHR 2.73, 95% CI 1.42 to 5.26). Predictors of a mental illness diagnosis were maternal age, delivery year, medical comorbidity, number of prenatal visits, family physician obstetrical care and infant mortality.ConclusionWomen with IBD were at an increased risk of new-onset psychiatric diagnosis in the postpartum period, but not during pregnancy. Providers should look to increase opportunities for prevention, early identification and treatment accordingly.

The Impact

Abstract Background The presence of serrated lesions (SLs) is an established risk factor for colorectal neoplasia development in the general population. However, the impact of SLs on the colorectal neoplasia risk in inflammatory bowel disease (IBD) patients is unknown. In addition, SLs might have been misclassified in IBD patients in the past, in part due to revisions of classification systems. Presently, SLs are categorised as hyperplastic lesions, sessile SLs, and traditional serrated adenomas. We aimed (1) to compare the colorectal neoplasia risk in IBD patients with SLs vs. IBD patients without SLs, and 2) to study the subclassification of SLs in IBD patients before and after histopathological review by two expert gastrointestinal pathologists. Methods We identified all IBD patients with colonic SLs from 1996 to 2019 in a tertiary referral centre using the local histopathology database. Patients with neoplasia prior to SL diagnosis were excluded. Clinical data from patients’ charts were retrieved until June 2019. A subgroup of 135 SLs was reviewed by two pathologists. The log-rank analysis was used to compare the cumulative (advanced) neoplasia incidence in IBD patients with SL vs. IBD patients without SL undergoing surveillance in the same time period. Patients were censored at the end of surveillance or at colectomy. Results We identified 376 SLs in 204 IBD patients (61.9% ulcerative colitis (UC)). In the original reports, 91.9% was classified as a hyperplastic lesion. After histopathological review, 120/136 (88%) of the SLs were confirmed (16 were no SL). Of the 120 confirmed SLs, 62.2% was classified as a sessile SL, 37.8% as a hyperplastic lesion, and 0.8% as a traditional serrated adenoma. The mean time from IBD diagnosis to the first serrated lesion was 14.3 ( ± 12.3) years. A total of 41/204 (20.0%) of patients developed neoplasia (3 CRC, 3 HGD, and 35 LGD; including 2 HGD and 17 LGD at the moment of serrated lesion detection). In the 304 patients without SL (52.6% UC), 63 developed neoplasia (20.7%; 8 CRC, 5 HGD and 50 LGD). Patients who received follow-up colonoscopies after SL (n = 127) had an increased cumulative risk of neoplasia (p < 0.01), but no increased risk of advanced neoplasia (p = 0.50) compared with the group of IBD patients without SL (Figure 1). Conclusion The presence of SLs in IBD patients was associated with a relatively high risk of synchronous colorectal neoplasia as well as an increased risk of subsequent neoplasia, although not with an increased risk of advanced neoplasia. Histopathological review confirmed the SL diagnosis in the majority of lesions, although a large proportion of the hyperplastic lesions was reclassified as a sessile SL.
