    Background & Aims Irritable bowel syndrome (IBS) is associated with significant disease burden and decreased quality of life (QOL). We investigated the effects of IBS on different areas of daily function and compared these among disease subtypes. Methods The Life with IBS survey was conducted by Gfk Public Affairs & Corporate Communications from September through October 2015. Respondents met Rome III criteria for constipation-predominant or diarrhea-predominant IBS (IBS-C and IBS-D, respectively). Data were collected from 3254 individuals (mean age, 47 years; 81% female; and 90% Caucasian) who met IBS criteria. Results Respondents who were employed or in school (n = 1885) reported that IBS symptoms affected their productivity an average of 8.0 days out of the month and they missed approximately 1.5 days of work/school per month because of IBS. More than half the individuals reported that their symptoms were very bothersome. Individuals with IBS-C were more likely than with IBS-D to report avoiding sex, difficulty concentrating, and feeling self-conscious. Individuals with IBS-D reported more avoidance of places without bathrooms, difficulty making plans, avoiding leaving the house, and reluctance to travel. These differences remained when controlling for symptom bothersomeness, age, sex, and employment status. In exchange for 1 month of relief from IBS, more than half of the sample reported they would be willing to give up caffeine or alcohol, 40% would give up sex, 24.5% would give up cell phones, and 21.5% would give up the internet for 1 month. Conclusions Although the perceived effects of IBS symptoms on productivity are similar among its subtypes, patients with IBS-C and IBS-D report differences in specific areas of daily function.

    Pancreatic enzyme supplementation versus placebo for improvement of gastrointestinal symptoms in non-responsive celiac disease: A cross-over randomized controlled trial
    (Frontiers Media, 2023-01-04) Yoosuf, Shakira; Barrett, Caitlin G.; Papamichael, Konstantinos; Madoff, Sarah E.; Kurada, Satya; Hansen, Joshua; Silvester, Jocelyn A.; Therrien, Amelie; Singh, Prashant; Dennis, Melinda; Leffler, Daniel A.; Kelly, Ciaran P.; Medicine, School of Medicine
    Background: Pancreatic Exocrine Insufficiency (PEI) is a possible cause of recurrent/persistent symptoms in celiac disease. Although pancreatic enzyme supplementation may be used to treat non-responsive celiac disease (NRCD) in clinical practice, clinical outcomes are variable and there is limited and low quality evidence to support this practice. The aim of this study was to assess the efficacy of pancreatic enzyme supplements (PES) for improvement of gastrointestinal symptoms in NRCD. Methods: Prospective, randomized, placebo-controlled, double-blind, cross-over trial in adults with NRCD examining Celiac Disease-Gastrointestinal Symptom Rating Scale (CeD-GSRS) scores on PES (pancrelipase co-administered with omeprazole) versus placebo (omeprazole only) during a 10-day treatment period. The study was registered under the clinical trials registry (https://clinicaltrials.gov/ number, NCT02475369) on 18 Jun 2015. Results: Twelve participants (nine female) were included in the per-protocol analysis; one participant had low fecal elastase-1. Pancrelipase was not associated with significant change in CeD-GSRS compared to placebo (-0.03 versus -0.26; P = 0.366). There was a significant decrease in mean values of total CeD-GSRS scores (3.58 versus 2.90, P = 0.004), abdominal pain (2.92 versus 2.42, P = 0.009), and diarrhea sub-scores (3.44 versus 2.92, P = 0.037) during the run-in period with omeprazole. Conclusion: In this prospective, cross-over randomized, placebo-controlled study, PES did not improve symptoms in patients with NRCD. It is unclear whether this is a trial effect or related to administration of omeprazole.
