Our findings show that zinc supplementation can resolve permeability alterations in patients with Crohn's disease in remission. Improving intestinal barrier function may contribute to reduce the risk of relapse in Crohn's disease.
Fecal calprotectin and lactoferrin appear to be equally recommendable as inflammatory disease markers in patients with lower gastrointestinal symptoms. Both tests are needed to accurately discriminate activity in inflammatory bowel disease patients.
Depletion of antioxidants is likely to be important in the pathophysiology of IBD: UC and CD patients show increased free radical peripheral leukocyte DNA damage and decreased plasma antioxidant defenses. These results indicate the necessity of further studies to establish whether optimal vitamin status may improve the clinical course of UC and CD.
Pylera achieved a remarkable eradication rate in clinical practice, irrespective if it was used as first treatment or as a rescue therapy. Treatment-emergent adverse events were uncommon generally mild.
SUMMARY
BackgroundCyclic administration of rifaximin in association with dietary fibre achieves symptomatic relief in uncomplicated diverticular disease (DD) by means of a still undefined mechanism.
To date, data on effectiveness and safety of Adalimumab (ADA) biosimilars in inflammatory bowel diseases (IBDs) are lacking. Therefore, we aimed to verify the ability of ABP501 and SB5 to maintain the clinical and biochemical response induced by the ADA originator, after switching to them. We prospectively analyzed data collected from 55 patients with IBD who switched to ABP501, and 25 patients with IBD who switched to SB5, from ADA originator at four IBD Units between 2018 and 2020. In addition, we included an age and sex-matched control group (n = 38) who continued ADA originator for at least two years and who did not switch to a biosimilar drug. Clinical and biochemical data (C-Reactive Protein (CRP), fecal calprotectin (FC)), concomitant steroid and/or immunosuppressant therapy at the time of the switch and after six months were collected. At six months, in the ABP501 group, we did not observe statistically significant modifications in clinical activity of disease (p = 0.09) and FC values (p = 0.90). Some patients (n = 8) needed to add steroids at six months after switching (p = 0.01), however the need for optimization was not significant between the two timepoints (p = 0.70). Finally, 14.5% patients stopped therapy after six months. Similarly, in the SB5 group we observed a stability of clinical activity and FC values (p = 0.90 and p = 0.20), and a concomitant statistically significant decrease in CRP (p = 0.03). There were no differences in steroids/immunosuppressants need or optimizing biological therapy in this group. Finally, drug survival curves of patients who switched from originator to ABP501 and those who continued ADA originator were similar (p = 0.20). Overall, biosimilar drugs seem to be as effective and safe as the originator. Further larger and longer studies are mandatory to understand the clinical implications of these findings.
Restorative proctocolectomy (RPC) is the favorite operation for ulcerative colitis, but it may influence health-related quality of life (HRQL). Our aims were to determine the long-term HRQL of patients and its modifications after a 5-year follow-up and to identify any risk factor for a worse outcome. We enrolled 36 patients submitted to RPC (mean follow-up 8.4 +/- 4.7 years), 36 ulcerative colitis (UC) patients, and 36 healthy subjects. We used a previously validated questionnaire that explored bowel symptoms, systemic symptoms, emotional function, and social function. A series of 17 patients had completed the same questionnaire 5 years earlier. Clinical and surgical factors were investigated. Statistical analysis was performed with Student's t-test, Wilcoxon matched-pairs test, and Fisher's exact test. The scores of the RPC patients were significantly better than those of moderate or severe UC patients, similar to those with remission/mild UC, and higher than those of the controls. The scores of patients interviewed 5 years earlier did not change in the present study, except for patients during the first postoperative year, in whom the scores were now significantly better. The analysis of RPC patients in subgroups showed that the use of drugs, high stool frequency, pouchitis, pelvic complications, and younger age at UC diagnosis worsened the HRQL outcome. We concluded that RPC patients, after a long-term follow-up, had an HRQL similar to that of the remission/mild UC patients. Recently operated patients improved their quality of life mainly because of improved emotional function, and patients who had been operated on for a longer time maintained their HRQL. HRQL is influenced by drugs, stool frequency, pouchitis, postoperative pelvic complications, and age at diagnosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
