OBJECTIVES: 5-aminosalicylates (5-ASA) are frequently continued in patients with moderate-severe ulcerative colitis (UC), even after escalation to biologic agents, without evaluation of the benefit of this approach. We conducted an individual participant data (IPD) pooled analysis of trials of infliximab and golimumab in UC, to evaluate whether concomitant use of 5-ASA modifies clinical outcomes among anti-tumor necrosis factor (TNF)-α-treated patients. METHODS: We included IPD from five trials of infliximab and golimumab in patients with moderate-severe UC (ACT-1 and -2, PURSUIT-SC, PURSUIT-M, NCT00336492)...

5-aminosalicylic acid has been reported to be able of inducing acute pancreatitis as an adverse reaction. However, in most case reports, rechallenge of the drug is missing; therefore, evidence is still needed to confirm its role in the clinical course of acute pancreatitis and its influence on the outcome. Here, we report a case of recurrent acute pancreatitis secondary to 5-aminosalicylic acid, with positive unintentional rechallenge. A systematic search of the literature was performed and 42 cases from 35 articles were summarized concerning the clinical course of 5-aminosalicylic acid induced acute pancreatitis...

5-Aminosalicylic acid (5-ASA) is an aminosalicylate anti-inflammatory drug, which is also known as mesalazine or mesalamine. Currently employed in treating inflammatory bowel disease, ulcerative colitis, inflamed anus or rectum and maintain remission in Crohn's disease. Evidence from the researchers highlighted its significant re-epithelization in allergic asthma, aphthous and gastric ulcerative conditions. The objective of the study was to formulate the pluronic lecithin organogel (PLO) containing 5-ASA and evaluate its wound healing ability in a full thickness excision wound rat model...

Diverticulosis is a common anatomical condition, which appears to be age-dependent. Individuals who develop chronic gastrointestinal symptoms or complications are referred to as having diverticular disease. Although the diagnosis of this condition can be relatively straightforward, randomized controlled trials are scarce and management often follows tradition rather than principles of evidence-based medicine. This report deals with the topics discussed during a symposium held during the United European Gastroenterology Week (Barcelona, October 2017)...

Mesalazine (5-ASA) is an aminosalicylate anti-inflammatory drug capable of inducing μ-protocadherin, a protein expressed by colorectal epithelial cells which is downregulated upon malignant transformation. Treatment with 5-ASA restores μ-protocadherin expression and promotes the sequestration of β-catenin to the plasma membrane. Here we show that 5-ASA-induced μ-protocadherin expression is directly regulated by the KLF4 transcription factor. In addition, we suggest the existence of a dual mechanism whereby 5-ASA-mediated β-catenin inhibition is caused by μ-protocadherin-dependent sequestration of β-catenin to the plasma membrane and by the direct binding of KLF4 to β-catenin...

Colitis is a chronic inflammation and ulcer on the inner lining of the large intestine. For many centuries Ocimum gratissimum (OG) leaves have been used in folk medicine in Nigeria to treat inflammatory bowel diseases, however, to date, the anti-colitis effects of OG have not been scientifically proven. In this study we investigated the effects of polyphenol rich extract of Ocimum gratissimum (PREOG) leaf on colonic mucosa injury in colitis, its mechanisms, initial administration time and dosage. Dextran sodium sulfate (DSS)-induced rat colitis models was used...

Chronic beryllium disease is a granulomatous lung disease, characterized by the accumulation of macrophages and beryllium-specific CD4+ T-cells that proliferate and produce T-helper cell type 1 cytokines. Previous studies indicate that beryllium-mediated oxidative stress enhances cytokine response in chronic beryllium disease CD4+ T-cells. 5-Aminosalicylic acid (5-ASA) is currently used to treat inflammatory bowel disease and has both antioxidant and antiinflammatory actions. We hypothesized that 5-ASA therapy may be a beneficial therapy in chronic beryllium disease...

Excessive hydrogen sulfide (H2 S) production from gut microbial metabolism may have clinically important relevance in the pathogenesis of gut disorders, including ulcerative colitis. However, little is known regarding factors that alter its production. Using a newly-designed in vitro gas-profiling technology, the study aimed to verify real-time H2 S measurement reproducibility and thereafter, assess its production following exposure to dietary factors and 5-aminosalicylate acid (5-ASA). Measurements of H2 S, carbon dioxide, hydrogen and methane measurements were compared between gas-profiling systems...
