Aim: The short-chain fatty acid, acetate, propionate and butyrate are end products of fermentation by intestinal microflora of the indigestible material, mainly carbohydrates, reaching the colon and are essential for the vital function of the colonic cells. Butyric acid furnishes energy to the cells of the colon and may play an anti-inflammatory role in pathologies of large bowel. Low concentrations of butyrate and of short-chain fatty acids have been found in the colon of patients with ulcerative colitis and this may justify therapy with butyrate and mesalazine in this disease. The aim of the paper was to evaluate the efficacy of treatment with butyric acid and mesalazine in reducing relapse of mild to moderate ulcerative colitis in affected patients.
Methods: An open study was conducted by 19 Italian Gastrointestinal Units, forming part of the GISDI study Group, in 216 patients with ulcerative colitis who showed an incomplete response to standard mesalazine treatment. The treatment proposed is mesalazine (800 mg x3) + 3 butyrate 0.3 g + 0.250 inulin tablets, in a formulation resistant to intestinal absorption (ZACOL NMX, Bioactival).
Results: The results obtained indicate that the addition of 3 tablets/die of ZACOL-MNX is effective in reducing disease activity, with a marked improvement of symptoms and in the endoscopic appearance of mucosa.
Conclusion: These findings prompt a further double-blind investigation to better define the efficacy of the proposed treatment.

Purpose: In this study, we investigated the progression of high-grade dysplasia (HGD)/CRC in patients with hereditary colorectal cancer syndromes (HCSS) and concomitant inflammatory bowel diseases (IBDs).
Methods: We described the natural history of a series of patients with confirmed diagnosis of hereditary colorectal cancer syndromes (HCCSs) and concomitant IBDs who were referred to the Hereditary Digestive Tumors Registry at the Fondazione IRCCS Istituto Nazionale dei Tumori of Milan.
Results: Between January 1989 and April 2024, among 450 patients with APC-associated polyposis and 1050 patients with Lynch syndrome (LS), we identified six patients with IBDs (five with UC, one with ileal penetrating CD) and concomitant HCCSs (five with LS, one with APC-associated polyposis).

Objective: To develop and validate a prognostic model for risk-stratified monitoring of 5-aminosalicylate nephrotoxicity.
Methods: This UK retrospective cohort study used data from the Clinical Practice Research Datalink Aurum and Gold for model development and validation respectively. It included adults newly diagnosed with inflammatory bowel disease and established on 5-aminosalicylic acid (5-ASA) treatment between 1 January 2007 and 31 December 2019.

Ethnopharmacological Relevance: Ulcerative colitis (UC) is a chronic form of inflammatory bowel disease, which current treatments often show limited effectiveness. Ferroptosis, a newly recognized form of programmed cell death has been implicated in UC pathogenesis, suggesting that it may be viable therapeutic target. Tetrastigma hemsleyanum (TH) has shown potential anti-UC effects, though it is unclear whether its therapeutic benefits are mediated by ferroptosis.

Background: Ulcerative colitis (UC) is a persistent chronic, non-specific inflammatory disease, and macrophages play a crucial role in its pathogenesis. Spleen tyrosine kinase (Syk) is strongly associated with the pathogenesis of several inflammatory diseases. However, the role of Syk in the pathogenesis of UC is still obscure.
