Zinc Deficiency is Associated with Poor Clinical Outcomes in Patients with Inflammatory Bowel Disease.

ABSTRACT: Zinc plays a pivotal role in wound repair, tissue regeneration, and the immune response. Although zinc deficiency is common in patients with inflammatory bowel disease (IBD), the impact of low serum zinc levels on disease course is not known.Patients enrolled in a prospectively collected IBD registry with at least 2 serum zinc measurements were included in the analysis. Using a logistic regression model, rates of IBD-related surgeries, IBD-related hospitalizations, and IBD-related complications were evaluated after a diagnosis of zinc deficiency (serum concentration <0.66 ?g/mL) compared with those with normal zinc concentrations. In patients who were zinc deficient, outcomes were also analyzed between those who had normalization of zinc levels within 12 months and those who remained deficient.A total of 773 patients with Crohn's disease (CD) and 223 with ulcerative colitis (UC) were included in the analysis. After adjusting for covariates, zinc deficiency was associated with an increased risk of subsequent hospitalizations, surgeries, and disease-related complications in patients with CD and UC (CD: hospitalizations, odds ratio 1.44, 95% confidence interval [1.02-2.04]; surgeries, 2.05 [1.38-3.05]; complications, 1.50 [1.04-2.15]; UC: hospitalizations, 2.14 [1.07-4.29]; surgeries, 1.64 [0.59-4.52]; complications, 1.97 [0.94-4.11]). Normalization of zinc was associated with improvement in these outcomes in patients with both CD and UC.Patients with IBD with serum zinc deficiency are more likely to have adverse disease-specific outcomes. As these outcomes improve with normalization of zinc, the results from this study support the role for close monitoring and replacement of zinc in patients with IBD.

Project description:ObjectiveProton pump inhibitor (PPI) use has been associated with reduced diversity of the gut microbiome and may lead to worse clinical outcomes in inflammatory bowel disease (IBD). We aimed to evaluate whether PPI use affects clinical outcomes in a real-world setting.DesignHealthcare claims data of adult IBD patients were obtained from the IBM MarketScan Database. Multivariable analysis and propensity score-matched analysis were performed to assess associations between PPI use and new biologic start, and IBD-related hospitalizations and surgeries.ResultsA total of 46,234 IBD patients were identified (6,488 (14%) and 39,746 (86%) patients with and without PPI, respectively). Patients on PPI were more likely to be older, female, and smokers and less likely to be on immunomodulators. Multivariable analyses demonstrated that PPI use was associated with new biologic start (odds ratio (OR) 1.11, 95% confidence interval (CI) 1.04-1.18), and IBD-related admissions (OR 1.95, 95% CI 1.74-2.19) and surgeries (OR 1.46, 95% CI 1.26-1.71). Following propensity score matching, patients on PPI remained more likely to start a new biologic (23% vs 21%, p = 0.011), and have IBD-related admissions (8% vs 4%, p < 0.001) and surgeries (4% vs 2%, p < 0.001). Subgroup analyses stratified by age, smoking, and glucocorticoid use showed similar results. There was a dose-response relationship between the number of PPI prescriptions and the risk of new biologic use (p < 0.001) and IBD-related admissions (p < 0.001).ConclusionPPI use was associated with worse clinical outcomes in patients with IBD in the real-world setting. Further studies are warranted to validate these findings, but caution may be needed when prescribing a PPI to IBD patients.Study highlights WHAT IS KNOWNProton pump inhibitors (PPIs) are one of the most prescribed therapies in the United States (US).Reduction of gastric acid secretion by PPI use increases the risk of imbalance in gut microbiota composition and may increase the risk of enteric infections.Recent studies have reported that the use of PPI was associated with development of inflammatory bowel disease (IBD) and reduced rates of remission in patients on infliximab therapy, which may be due to alterations of intestinal microbiota.WHAT IS NEW HEREIn a large real-world US healthcare database study, IBD patients with PPI use were more likely to have a new biologic medication started, have an IBD-related surgery, and have an IBD-related hospitalization, which remained significant after adjusting for confounders by multivariable analysis, propensity-score matched analysis, and subgroup analysis.Appropriate clinical review of PPI necessity may need to be performed in patients with IBD when considering prescribing a PPI or who are already on PPI therapy.
