    Nonasthmatic eosinophilic bronchitis in an ulcerative colitis patient - a putative adverse reaction to mesalazine: A case report and review of literature. Cernomaz Andrei Tudor,Bordeianu Gabriela,Terinte Cristina,Gavrilescu Cristina Maria World journal of clinical cases BACKGROUND:Lung and airway involvement in inflammatory bowel disease are increasingly frequently reported either as an extraintestinal manifestation or as an adverse effect of therapy. CASE SUMMARY:We report a case of a patient with ulcerative colitis controlled under mesalazine treatment who presented with chronic cough and hemoptysis. Chest computed tomography and bronchoscopy findings supported tracheal involvement in ulcerative colitis; pathology examination demonstrated an unusual eosinophil-rich inflammatory pattern, and together with clinical data, a nonasthmatic eosinophilic bronchitis diagnosis was formulated. Full recovery was observed within days of mesalazine discontinuation. CONCLUSION:Mesalazine-induced eosinophilic respiratory disorders have been previously reported, generally involving the lung parenchyma. To the best of our knowledge, this is the first report of mesalamine-induced eosinophilic involvement in the upper airway. 10.12998/wjcc.v8.i18.4162
    Mesalazine-related lung disease in a patient with ulcerative colitis: A case report. Huang Po-Han,Kuo Chia-Jung,Lin Chang-Wei,Cheng Yu-Ming,Hu Han-Chung,Lin Chun-Yen,Su Ming-Yao,Chiu Cheng-Tang Medicine RATIONALE:Mesalazine is widely used to treat inflammatory bowel disease (IBD). However, discriminating between pulmonary manifestations of IBD and drug-related lung disease remains a challenge. There were few case reports of mesalazine-related organizing pneumonia so far. PATIENT CONCERNS:A 75-year-old female was diagnosed with ulcerative colitis and took mesalazine over a period of 2 years and 8 months. She presented with progressive shortness of breath for 3 days and visited our emergency department. Chest radiography showed increased bilateral infiltrates. During hospitalization her clinical condition deteriorated, and she was transferred to our intensive care unit under noninvasive ventilator support. DIAGNOSIS:Computed tomography (CT) scan showed diffuse peribronchial and subpleural consolidations in bilateral lungs. Possible etiologies of interstitial lung disease were surveyed, including various infectious diseases and connective tissue diseases. Transbronchial lung biopsy showed characteristic features of organizing pneumonia. INTERVENTIONS:Under the consideration of mesalazine-related lung disease, mesalazine was discontinued early in disease course and steroid therapy was given. OUTCOMES:The patient was discharged from hospital with improved clinical symptoms and radiographic images. LESSONS:Although this patient suffered a life-threatening adverse event, prompt diagnosis with proper management can result in a favorable outcome. 10.1097/MD.0000000000013242
    Utility of Mesalazine in Familial Adenomatous Polyposis: Clinical Report of Reduction of Polyp Size in Patients with Ulcerative Colitis, and Safety Examination in Familial Adenomatous Polyposis Patients. Ishikawa Hideki,Mutoh Michihiro,Abe Takashi,Nakajima Takeshi,Takeuchi Yoji,Ezoe Yasumasa,Wakabayashi Keiji,Doyama Hisashi,Sakai Toshiyuki Pharmacology Mesalazine is the gold standard drug for treatment of ulcerative colitis (UC). Here, we describe 4 cases of familial adenomatous polyposis (FAP) patients with UC that showed reduction of intestinal polyp diameter by mesalazine treatment. Of note, the effects of mesalazine on the development of intestinal polyps in FAP patients have not been reported, and we further investigated whether the short-term use of high-dose mesalazine (4 g/day) has harmful effects on FAP patients or not. The authors found that the treatment showed slightly adverse events in FAP patients. However, mesalazine tended to reduce the number of colon polyps in male subjects with FAP. This report provides basic information for planning a double-blind, randomized, clinical trial that aims to show mesalazine's potential to suppress intestinal polyp development in FAP. 10.1159/000500226
    Budesonide Multimatrix Is Efficacious for Mesalamine-refractory, Mild to Moderate Ulcerative Colitis: A Randomised, Placebo-controlled Trial. Rubin David T,Cohen Russell D,Sandborn William J,Lichtenstein Gary R,Axler Jeffrey,Riddell Robert H,Zhu Cindy,Barrett Andrew C,Bortey Enoch,Forbes William P Journal of Crohn's & colitis Background and Aims:Safety and efficacy of budesonide multimatrix, an oral extended-release second-generation corticosteroid designed for targeted delivery throughout the colon, were examined for induction of remission in patients with mild to moderate ulcerative colitis refractory to baseline mesalamine therapy. Methods:A randomised, double-blind, placebo-controlled, multicentre trial evaluated efficacy and safety of budesonide multimatrix for induction of remission [ulcerative colitis disease activity index score ≥ 4 and ≤ 10] in 510 adults randomised to once-daily oral budesonide multimatrix 9 mg or placebo for 8 weeks. Patients continued baseline treatment with oral mesalamine ≥ 2.4 g/day. Results:Combined clinical and endoscopic remission at Week 8 was achieved by 13.0% and 7.5% of patients receiving budesonide multimatrix [n = 230] or placebo [n = 228], respectively, in the modified intention-to-treat population [p = 0.049]. Clinical remission [ulcerative colitis disease activity index rectal bleeding and stool frequency subscale scores of 0] was similar in both groups [p = 0.70]. More patients receiving budesonide multimatrix vs placebo achieved endoscopic remission [ulcerative colitis disease activity index mucosal appearance subscale score of 0; 20.0% vs 12.3%; p = 0.02] and histological healing [27.0% vs 17.5%; p = 0.02]. Adverse event rates were similar [budesonide multimatrix, 31.8%; placebo, 27.1%]. Mean morning cortisol concentrations decreased at Weeks 2, 4, and 8 with budesonide multimatrix but remained within the normal range. Conclusion:Budesonide multimatrix was safe and efficacious for inducing clinical and endoscopic remission for mild to moderate ulcerative colitis refractory to oral mesalamine therapy. 10.1093/ecco-jcc/jjx032

    Multidonor intensive faecal microbiota transplantation for active ulcerative colitis: a randomised placebo-controlled trial. Paramsothy Sudarshan,Kamm Michael A,Kaakoush Nadeem O,Walsh Alissa J,van den Bogaerde Johan,Samuel Douglas,Leong Rupert W L,Connor Susan,Ng Watson,Paramsothy Ramesh,Xuan Wei,Lin Enmoore,Mitchell Hazel M,Borody Thomas J Lancet (London, England) BACKGROUND:The intestinal microbiota is implicated in the pathogenesis of ulcerative colitis. Faecal microbiota transplantation is a novel form of therapeutic microbial manipulation, but its efficacy in ulcerative colitis is uncertain. We aimed to establish the efficacy of intensive-dosing, multidonor, faecal microbiota transplantation in active ulcerative colitis. METHODS:We conducted a multicentre, double-blind, randomised, placebo-controlled trial at three hospitals in Australia. We randomly allocated patients with active ulcerative colitis (Mayo score 4-10) in a 1:1 ratio, using a pre-established randomisation list, to either faecal microbiota transplantation or placebo colonoscopic infusion, followed by enemas 5 days per week for 8 weeks. Patients, treating clinicians, and other study staff were unaware of the assigned treatment. Faecal microbiota transplantation enemas were each derived from between three and seven unrelated donors. The primary outcome was steroid-free clinical remission with endoscopic remission or response (Mayo score ≤2, all subscores ≤1, and ≥1 point reduction in endoscopy subscore) at week 8. Analysis was by modified intention-to-treat and included all patients receiving one study dose. We performed 16S rRNA stool analysis to assess associated microbial changes. This trial is registered with ClinicalTrials.gov, number NCT01896635. The trial has ended; this report presents the final analysis. FINDINGS:From November, 2013, to May, 2015, 85 patients were enrolled to our trial, of whom 42 were randomly assigned faecal microbiota transplantation and 43 were allocated placebo. One patient assigned faecal microbiota transplantation and three allocated placebo did not receive study treatment and were excluded from the analysis. The primary outcome was achieved in 11 (27%) of 41 patients allocated faecal microbiota transplantation versus three (8%) of 40 who were assigned placebo (risk ratio 3·6, 95% CI 1·1-11·9; p=0·021). Adverse events were reported by 32 (78%) of 41 patients allocated faecal microbiota transplantation and 33 (83%) of 40 who were assigned placebo; most were self-limiting gastrointestinal complaints, with no significant difference in number or type of adverse events between treatment groups. Serious adverse events occurred in two patients assigned faecal microbiota transplantation and in one allocated placebo. Microbial diversity increased with and persisted after faecal microbiota transplantation. Several bacterial taxa were associated with clinical outcome; in particular, the presence of Fusobacterium spp was associated with lack of remission. INTERPRETATION:Intensive-dosing, multidonor, faecal microbiota transplantation induces clinical remission and endoscopic improvement in active ulcerative colitis and is associated with distinct microbial changes that relate to outcome. Faecal microbiota transplantation is, thus, a promising new therapeutic option for ulcerative colitis. Future work should focus on precisely defining the optimum treatment intensity and the role of donor-recipient matching based on microbial profiles.
