BACKGROUNDS: In some patients with ulcerative proctitis (UP), skip inflammation is noted in the right side of the colon, but little is known about its clinical course. The aim of this study was to evaluate the clinical course of UP with skip inflammation and the efficacy of topical 5-ASA monotherapy. METHODS: We reviewed the data of 388 patients with an initial diagnosis of UP from January 2005 to October 2015. We matched each UP patient with skip inflammation 1:2 with controls who had UP without skip inflammation; to reduce bias, we matched the controls with the cases by age, gender, and initial disease activity...

BACKGROUND: 5-Aminosalicylic acids (5-ASA) are effective for ulcerative colitis (UC) as a maintenance therapy. It is not clear when and how to reduce a dose of 5-ASA after inducing remission. We aimed to investigate the clinical characteristics and evaluate the risk factors of relapse for UC patients receiving 5-ASA. METHODS: The medical records of prospectively registered UC patients who received oral 5-ASA as maintenance therapy between January and December 31, 2014, were investigated...

INTRODUCTION: Chronic beryllium disease (CBD) is characterized by accumulation of macrophages and beryllium-specific CD4(+) T cells that proliferate and produce Th1 cytokines. 5-Amino salicylic acid (5-ASA) is currently used to treat inflammatory bowel disease and has both antioxidant and anti-inflammatory actions. We hypothesized that 5-ASA may be a beneficial therapeutic in CBD. METHODS: Seventeen CBD patients were randomized 3:1 to receive 5-ASA 500-mg capsules or placebo four times daily for 6 weeks orally...

Adherence is pivotal but challenging in ulcerative colitis (UC) treatment. Many methods to assess adherence are subjective or have limitations. (Nac-)5-aminosalicylic acid (5-ASA) urinalysis by High-Performance Liquid Chromatography (HPLC) seems feasible and reproducible in healthy volunteers. We performed a prospective study in adult quiescent UC patients to evaluate the feasibility of spot (Nac-)5-ASA urinalysis by HPLC to assess adherence in daily IBD care. Twenty-nine patients (51.7% male, mean age 52 ± 11 yrs) were included (median FU 9 months) and collected weekly spot urine samples...

Given the central role of gluten in the pathogenesis of celiac disease (CD), a strict gluten-free diet (GFD) is the only validated treatment able to restore epithelium integrity and eliminate risks of complications. The risk of gluten contamination and the persistence of inflammation, even in patients strictly adhering to GFD, may render this treatment not always effective claiming the necessity of different new solutions. Oxidative and nitrosative stress have been indicated to play a pathophysiological role in CD...

OBJECTIVE: Ulcerative colitis (UC) is a condition characterized by chronic inflammation of the colon and is related to a genetically and environmentally-generated altered immune response to the enteric microbiome. Previous work in the PI laboratory suggests that children with UC harbor a unique gut microbial profile, which can predict therapeutic response. We hypothesized that children with ulcerative colitis will benefit from fecal transplant therapy (FMT). To this date there have been a number of reports describing the role of FMT in this disease albeit without uniform success and without controlled pediatric studies...

BACKGROUND: Diverticular disease is a common condition that increases in prevalence with age. Recent theories on the pathogenesis of diverticular inflammation have implicated chronic inflammation similar to that seen in ulcerative colitis. Mesalamine, or 5-aminosalicylic acid (5-ASA), is a mainstay of therapy for individuals with ulcerative colitis. Accordingly, 5-ASA has been studied for prevention of recurrent diverticulitis. OBJECTIVES: To evaluate the efficacy of mesalamine (5-ASA) for prevention of recurrent diverticulitis...

Mesalamine (5-ASA) consists of the first-line therapy for the treatment of ulcerative colitis; however, it has low bioavailability, can cause several systemic adverse events, and has low treatment adherence due to the inconvenient dosing scheme. In this work, a new drug delivery system consisting of chondroitin sulfate linked to 5-ASA was synthesized using a carbodiimide as conjugating agent. The system was characterized by spectroscopic techniques (UV, ATR-FTIR, XRD, and NMR (1)H) and thermal analysis (TG/DTG and DSC), suggesting the conjugation between the drug and the polymer...

Moringa (Moringa oleifera Lam.) seed extract (MSE) has anti-inflammatory and antioxidant activities. We investigated the effects of MSE enriched in moringa isothiocyanate-1 (MIC-1), its putative bioactive, on ulcerative colitis (UC) and its anti-inflammatory/antioxidant mechanism likely mediated through Nrf2-signaling pathway. Dextran sulfate sodium (DSS)-induced acute (n = 8/group; 3% DSS for 5 d) and chronic (n = 6/group; cyclic rotations of 2.5% DSS/water for 30 d) UC was induced in mice that were assigned to 4 experimental groups: healthy control (water/vehicle), disease control (DSS/vehicle), MSE treatment (DSS/MSE), or 5-aminosalicyic acid (5-ASA) treatment (positive control; DSS/5-ASA)...

We have developed a self-assembling polymeric nanocarrier to deliver the potent immunosuppressive drug Cyclosporine A (CsA) to inflammatory lesions in ulcerative colitis (UC) patients. Our nanocarrier has a high drug loading capacity and efficiently targets its CsA payload to the diseased tissue after local administration. Tissue drug levels were several orders of magnitude higher in animals suffering from a trinitrobenzene-sulfonic acid (TNBS) - induced colitis, compared to healthy control animals; no drug was detectable in the plasma, underlining the localized delivery strategy...

Sulfasalazine is an anti-inflammatory agent commonly used in the treatment of autoimmune conditions such as inflammatory bowel disease and rheumatoid arthritis. Sulfasalazine is converted by gut bacteria into sulfapyridine and the clinically active metabolite 5-aminosalicylic acid (5-ASA), and its efficacy is proportional to the 5-ASA concentration within the intestinal lumen. Renal complications are commonly reported for the chemically similar 5-ASA derivative mesalamine, but are not well-known side effects of sulfasalazine therapy...

BACKGROUND: In ulcerative colitis (UC) 5-aminosalicylic acid (5-ASA) is recommended as primary therapy for mild to moderate disease. Topical 5-ASA has been proven especially effective. In Crohn's disease (CD) the evidence for a beneficial role of 5-ASA is weak. We investigated the use of topical and systemic 5-ASA therapy in children and adolescents with inflammatory bowel disease. MATERIALS AND METHODS: Data of patients younger than 18 years, registered between April 2008 and December 2015 in the Swiss Inflammatory Bowel Disease Cohort, were analyzed...

BACKGROUND AND AIM: Prevalence of colonic diverticulosis is increasing worldwide with age, and up to 25% of patients who have colonic diverticulosis might experience diverticulitis. However, a definitive approach of preventing recurrent diverticulitis remains unknown. 5-aminosalicylic acid (5-ASA) agents are anti-inflammatory agents and have been used to prevent recurrent diverticulitis, and there have been some randomized, clinical trials (RCTs). However, the efficacy results for secondary prevention in uncomplicated diverticulitis differed across studies...

Crohn's disease (CD) and ulcerative colitis (UC) are types of chronic inflammatory bowel disease (IBD) of which the actual causes remain unknown. Emerging data indicate that alterations in cytokine synthesis may be involved in IBD pathogenesis. The aim of the present study was to determine whether the tumor necrosis factor (TNF)-α mRNA expression level and rs1799964 polymorphism are the genetic susceptibility component of IBD development. The TNF-α mRNA expression level of peripheral blood mononuclear cells (PBMCs) was measured using comparative reverse-transcription quantitative polymerase chain reaction (PCR)...
