Background: Malnutrition and lack of micronutrients are seen in many patients with ulcerative colitis (UC). Considering that vitamins play an important role in preventing or protecting against inflammation at the metabolic, physiological, and pathological levels, this research was aimed to investigate the effect of a number of vitamin B groups in improving UC.
Methods: Experimental colitis was induced by rectal administration of acetic acid (3%) in male Wistar rats, and mega doses of thiamine (20 mg/kg), riboflavin (15 mg/kg), pyridoxine (30 mg/kg), and cyanocobalamin (250 μg/kg) alone or in combination were administered intraperitoneally for 5 days.

Background And Aims: The advantages of endoscopic vs histologic assessments of inflammation in inflammatory bowel disease remain unclear. We compared endoscopic and histologic inflammation in a prospective cohort. Furthermore, in patients with discordant findings, we compared the ability of endoscopy vs histology to predict disease course.

Background: Immune checkpoint inhibitor (ICI)-induced colitis is a significant adverse event associated with ICI therapy, known to be linked to increased cytotoxic T-cell activity.
Objectives: To compare T-cell subsets based on the endoscopic features of ICI-induced colitis and to compare these findings with those of inflammatory bowel disease (IBD).
Design: Prospective cohort study.
Background: Recent biomedical research has shown the unusual, multisystem effects of coronavirus disease 2019 in humans. One specific sequela of a primary severe acute respiratory syndrome coronavirus 2 infection is the reactivation of latent viruses in various tissues, such as Epstein-Barr virus. Epstein-Barr virus has been identified in many inflammatory gastrointestinal lesions, such as microscopic gastritides and colitides.

Inflammatory bowel disease (IBD) encompasses Crohn's disease (CD) and ulcerative colitis (UC), is a major health problem on a global scale and its treatment is unsatisfactory. We aimed to investigate the effects of transauricular vagal nerve stimulation (tVNS) on inflammation in rats with IBD induced by trinitrobenzene sulfonic acid (TNBS). A total of 36 adult female Sprague-Dawley rats were given TNBS, or vehicle, and tVNS, or sham, every other day for 30 min for 10 days.
