Background: Practice guidelines recommend screening for hepatitis B virus (HBV) infection prior to initiating treatment of inflammatory bowel disease (IBD) with anti-tumor necrosis factor (anti-TNF) therapy. However, the adherence to these screening guidelines and the clinical outcomes of HBV reactivation following anti-TNF use are not well known., Methods: This is a retrospective cohort study using the Veterans Health Administration datasets for IBD patients with filled prescriptions for anti-TNFs from 2003 to 2011. Laboratory testing was used to define HBV screening status in the 12 months preceding anti-TNF initiation. Logistic regression models were used to identify predictors of HBV screening. Cases of potential HBV reactivation were identified using ICD-9 codes for HBV infection or acute liver failure or by medications used for HBV infection treatment, and manually reviewed for verification., Results: We identified 3357 IBD patients with filled prescriptions for anti-TNF medications. The HBV testing prior to anti-TNF initiation was 8.1% in 2003 and increased to 43.2% by 2011, with an overall rate of 23.7%. In multivariate analysis, African-American race, facilities with a higher volume of IBD patients, and facilities with an academic affiliation were associated with a higher probability of HBV screening. We did not identify a single case of confirmed clinically relevant HBV reactivation after anti-TNF initiation during 7210 patient-years of medication use., Conclusions: HBV screening rates prior to anti-TNF initiation are low among IBD patients, but have increased over time. Despite low rates of screening, clinically significant HBV reactivation after anti-TNF initiation in this US cohort was nonexistent.

Aim: To identify the frequency of hair loss among patients with inflammatory bowel disease (IBD) and associated clinical and disease related factors., Methods: We performed a cross sectional study in a tertiary referral adult IBD clinic. Self-reported history and characteristics of hair loss as well as clinical and demographic information were collected. Data were analyzed using univariate and multivariate analyses., Results: Two hundred and ten consecutive IBD patients were recruited; one hundred and fifty patients met predefined inclusion and exclusion criteria. Thirty-three percent of patients reported a history of hair loss. Age, gender, IBD type and disease duration were not associated with hair loss. Hair loss was reported less frequently among patients with use of mesalamine (54% vs 73%, P = 0.03) and anti-tumor necrosis factor medications (anti-TNF) (14% vs 40%, P = 0.001). In multivariate analyses adjusting for gender, IBD type and duration of disease, these associations with mesalamine and anti-TNF remained significant [(adjusted values for mesalamine (OR = 0.43, 95%CI: 0.19-0.86) and anti-TNFs (OR = 0.28, 95%CI: 0.08-0.98)]., Conclusion: Hair loss is common among patients with IBD. Mesalamine and anti-TNF medications were associated with lower odds of hair loss. Further studies are required to assess the mechanism of hair loss among patients with IBD.

Studies across medical disciplines have shown gaps in the care recommended in evidence based guidelines and the care actually delivered. Quality improvement projects using systematic audit and feedback interventions such as quality measures, will become increasingly important tools to address these gaps in care. These gaps are also apparent in the care of patients with inflammatory bowel disease. Multiple organizations, including the American Gastroenterology Association and the Crohn's and Colitis Foundation of America, have developed programs designed to implement quality measures to improve the care of inflammatory bowel disease (IBD) patients. Early results show promise of improving quality, but numerous barriers remain. Gastroenterologists need to be aware of these processes to provide the highest care possible to patients with IBD. We review the existing literature on approaches to quality improvement and their potential application and barriers when applied to IBD care.

The purpose of our experiment was to explore how stochastic (inter‐individual variation) gut microbiome composition may link to inflammatory bowel disease (IBD) susceptibility and guide the development of a perinatal preventative probiotic. Dextran sodium sulfate (DSS) was introduced to C57BL/BJ mice to induce acute colitis as a model of IBD. Potentially protective bacteria were identified using a discovery‐validation cohort approach toward stochastic DSS susceptibility. Lactobacilli (two different cocktails of L. reuteri and L. johnsonii strains) or control media were supplemented by mouth to dams prior to delivery and during lactation (i.e., perinatal probiotic). The pups were evaluated for DSS susceptibility at young adulthood. Fecal Lactobacillus was increased in the DSS‐resistant mice in both the discovery and validation cohorts. Maternal supplementation of female offspring with an L. reuteri cocktail (strains 6798‐1, 6798‐jm, and 6798‐cm) induced progressive microbiome separation and protection against colitis by young adulthood. Maternal supplementation of L. reuteri could confer protection against DSS colitis in young adult female mice. This work is the first to exploit stochastic mammalian microbiome variation to guide microbial therapeutic identification. Our findings underscore neonatal microbiome plasticity and set the stage for the potential development of perinatally deliverable protective probiotics against human IBD. [ABSTRACT FROM AUTHOR]

Background: Anemia is a common complication of inflammatory bowel disease (IBD). Despite existing guidelines for anemia in IBD, it is frequently under-treated and the prevalence of anemia has remained high. To address this gap, the Crohn's and Colitis Foundation developed the Anemia Care Pathway (ACP).Aims: To implement the ACP in a managed care setting and identify where it improves practice habits and where barriers remain.Methods: The ACP was implemented from July 2016 through June 2017 and retrospectively studied. Run charts were used to identify shifts in iron deficiency screening and treatment as well as anemia prevalence. Results were compared to those of other providers in the same center not using the ACP.Results: 640 IBD encounters were studied. In the ACP clinic (n = 213), anemics received iron therapy in only 30% of encounters at baseline but improved to 80%. Concurrently, anemia prevalence decreased from 48 to 25%. Screening for iron deficiency, however, did not improve. No shifts were seen in the non-ACP clinics (n = 427) across the same period despite awareness of the ACP and other guidelines.Conclusions: Across 1 year, we observed gaps in the screening and treatment of anemia in IBD. Although screening rates did not improve, the ACP appeared to reduce missed opportunities for iron therapy by about half. Most importantly, this was associated with an overall decrease in anemia prevalence. Future refinements to the ACP should be focused on enhanced screening and follow-up. [ABSTRACT FROM AUTHOR]

Background: The intestinal microbiota may influence inflammatory bowel disease (IBD) activity. Histamine 2 receptor antagonists (H2RAs) and proton pump inhibitors (PPIs) can alter the intestinal microbiota. The aim of this study was to assess the relationship between H2RAs, PPIs, and IBD-related outcomes. Methods: We conducted a case-control study of IBD patients using the Veterans Health Affairs databases. Cases were defined by their first instance of an IBD-related hospitalization or surgery and the exposure of interest was H2RA or PPI use 30 days prior to the outcome. Incidence density ratios were calculated using conditional logistic regression. Results: In a cohort of 58,459 patients with IBD, we found 4,887 cases and 9,761 controls with ulcerative colitis (UC) and 4,876 cases and 9,745 controls with Crohn disease (CD). Filled prescriptions for H2RAs were associated with an increased risk of IBD-related hospitalization or surgery in CD patients (adjusted incidence density ratio 1.18; 95% CI 1.03-1.34). A similar association was found for PPIs in UC patients (adjusted incidence density ratio 1.11; 95% CI 1.02-1.21) and CD patients (adjusted incidence density ratio 1.12; 95% CI 1.02-1.22). Conclusions: H2RAs and PPIs were associated with a modestly increased risk of IBD-related hospitalization or surgery. [ABSTRACT FROM AUTHOR]
