Aim: There is a paucity of data on the clinical course and the factors affecting the clinical course of herpes zoster (HZ) in inflammatory bowel disease (IBD). Our aim was to determine the impact of anti-TNF therapy and other factors on the clinical course of HZ in IBD patients. Methods: We conducted a retrospective cohort study among a cohort of nation-wide Veterans Affairs patients with IBD who developed incident HZ. The exposed group consisted of eligible study patients who were actively exposed to anti-TNF alone or anti-TNF plus thiopurines at the time of HZ onset...

INTRODUCTION: There is a lack of studies on the optimal anti-tumor necrosis factor (anti-TNF) agent for postoperative prophylaxis of Crohn's disease (CD) recurrence. Therefore, we conducted a network meta-analysis (NMA) of prospective trials to compare the efficacy of anti-TNF agents in the prevention of postoperative endoscopic and clinical recurrence of CD following ileocolonic resection. METHODS: We searched PubMed, EMBASE, the Cochrane Central Register of Controlled Trials, and recent American gastroenterology association (AGA) meeting abstracts through August 2017...

Portulaca oleracea L. is a traditional Chinese medicine, which has been used as adjuvant therapy for inflammatory bowel disease (IBD). However, the mechanism of its activity in IBD still remains unclear. Since previous studies have documented the anti-inflammatory effect of peroxisome proliferator activated receptors- γ (PPAR- γ ), Portulaca regulation of PPAR- γ in inflammation was examined in current study. Ulcerative colitis (UC) was generated by 5% dextran sulfate sodium (DSS) in mice and four groups were established as normal control, DSS alone, DSS plus mesalamine, and DSS plus Portulaca ...

We report a case of 26-year-old man who was admitted on our ward for the evaluation of ascites. He was a known case of inflammatory bowel disease(ulcerative colitis) and was on regular mesalamine therapy. On evaluation, he was having high serum ascites albumin gradient. CT scan of the abdomen revealed features of portal hypertension and non-visualisation of right and middle hepatic veins along with thrombus in inferior vena cava, suggesting a diagnosis of Budd-Chiari syndrome (BCS). There are only few case reports available showing association of BCS with UC...

Mesalamine is used as the first-line therapy for ulcerative colitis (UC). Although the exacerbation of symptoms of UC can occur in 2-4% of patients who are administered mesalamine (1-3), endoscopic features of the patients with this type of adverse events have rarely been reported. We show the colonoscopic findings of three patients who received mesalamine and manifested severe exacerbation of symptoms of UC. This article is protected by copyright. All rights reserved.

While the presence of intraepithelial lymphocytosis with surface epithelial damage is a unifying feature of lymphocytic colitis, there are non-classical features that create morphologic heterogeneity between cases. Limited data are available on the significance of these secondary histologic features. Cases of lymphocytic colitis diagnosed between 2002 and 2013 were identified using the Research Patient Data Registry of a tertiary referral center. Diagnostic biopsy slides were reviewed and evaluated for histologic features of lymphocytic colitis...

Background: Disease activity of patients with ulcerative colitis (UC) predicts health-related quality of life (HRQL) and work-related outcomes (eg, absenteeism, productivity). We tested whether outcomes differed among patients in complete (clinical and endoscopic) remission, partial remission, or not in remission following treatment with multimatrix mesalamine. Methods: Data were from an open-label, multicountry, prospective trial ( identifier: NCT01124149) of 717 adults with active mild-to-moderate UC treated with 4...

BACKGROUND: Fecal calprotectin (FC) correlates with clinical and endoscopic activity in ulcerative colitis (UC), and it is a good predictor of relapse. However, its use in clinical practice is constrained by the need for the patient to deliver stool samples, and for their handling and processing in the laboratory. The availability of hand held devices might spread the use of FC in clinical practice. OBJECTIVES: To evaluate the usefulness of a rapid semi-quantitative test of FC in predicting relapse in patients with UC in remission...

Ampholytic starch derivatives are proposed as a new class of excipients carrying simultaneously anionic carboxymethyl (CM) and cationic aminoethyl (AE) groups on starch (St) polymeric chains. Three different types of derivatives were obtained by using the same reagents and varying only the order of their addition in the reaction medium: in one step method (OS) the two reactants were added simultaneously, whereas in two steps method (TS) either CMSt or AESt were prepared separately in the first step, followed by subsequent addition of the second reactant...

BACKGROUND: Chitosan nanoparticles have the potential to be used as hydrophilic carrier systems since they can deliver drugs to specific sites and control the drug release rate. Moreover, control released systems are designed to minimize systemic absorption and to achieve optimum delivery of the biologically active mesalamine to the distal small intestine and the colon. OBJECTIVE: The current study investigated the development of new nanoparticulate drug delivery systems based on polyurethane-chitosan copolymers...

PURPOSE: Evaluate ex vivo the bacterial metabolism induced degradation rates of mesalamine (negative control), metronidazole and olsalazine in distal ileum and in cecum. METHODS: The contents of distal ileum and cecum were collected during colonoscopy under anaerobic conditions from twelve healthy adults in the fasted and in the fed state. To eliminate potential effects of enzymes that may exist in the fluid of lower intestine, each sample was ultracentrifuged and the precipitate was diluted with a volume of normal saline equivalent to that of the supernatant, after ultracentrifugation of intestinal contents from which the specific precipitate had been obtained...

BACKGROUND: Phthalates, such as dibutyl phthalate (DBP), are endocrine disruptors used in some medication coatings e.g., mesalamine to treat inflammatory bowel disease (IBD). OBJECTIVES: Taking advantage of different mesalamine formulations with/without DBP, we assessed whether DBP from mesalamine (>1000x background) altered serum hormones. METHODS: Men (N=73) with IBD participated in a crossover-crossback prospective study and provided up to 6 serum samples (2:baseline, 2:crossover, 2:crossback)...

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...

PURPOSE OF REVIEW: Post-infectious irritable bowel syndrome (PI-IBS) is characterized by persistent abdominal pain and diarrhea, typically following an episode of infectious gastroenteritis. The mechanisms that underlie IBS-D remain elusive, but PI-IBS provides a mechanistic model of this disorder. This review provides an up-to-date appraisal of the pathophysiology, clinical features, and management approaches for PI-IBS. RECENT FINDINGS: Disordered immune reactions and release of cytokines with resultant gut inflammation and dysfunction appear to be key features of PI-IBS...

The Multimatrix® (MMX®) preparation MMX® is a recently obtained drug formulation developed to facilitate release of high concentrations of active drugs into the colon, with a homogeneous distribution along all colonic segments, particularly the most distal ones; the distal colonic tracts, indeed, are the most difficult to reach in significant amounts when a drug is given orally. The MMX® formulation is characterized by a lipophilic matrix dispersed in a hydrophilic structure. Indeed, in the last few years, MMX® technology has been widely used in the development of various drugs for the treatment of inflammatory and infectious gastrointestinal diseases localized in the colon...

Refractory chronic colitis presents a medical and surgical challenge, and underlying etiologies are diverse with potential for misclassification as inflammatory bowel disease. We present an unusual case of chronic proctosigmoiditis with rare vascular etiology. A 48-year-old Caucasian male presented with severe diarrhea, weight loss, and abdominal pain. Computed tomography (CT) suggested proctosigmoiditis. Colonoscopy and biopsy findings were non-specific but were suggestive of ischemic etiology and venous congestion...
