Background. When used for oral treatment of inflammatory bowel disease, Asacol (a coated form of mesalazine = 5-aminosalicylic acid) can cause interstitial nephritis. The spectrum of severity, frequency of occurrence and the best renal function test to detect this complication are not known. The value of immunosuppression in addition to drug withdrawal is similarly undetermined. Methods. Four c...

BACKGROUND With greater use of immunomodulators in inflammatory bowel disease (IBD), it is uncertain whether concurrent therapy with both 5-aminosalicylic acid [5-ASA, mesalazine (mesalamine)] and an immunomodulator is necessary. AIM To determine whether concurrent therapy with both 5-ASA and immunomodulator(s) improves outcomes in IBD. METHODS Systematic review with search terms 'azathiopr...

OBJECTIVE To assess the benefits of different treatments that aim to prevent the endoscopic recurrence of Crohn's disease (CD) after ileal resection. METHODS Randomized controlled trials (RCTs) were searched from MEDLINE, Embase, and the Cochrane Central Database. All the included RCTs with an endoscopic recurrence outcome which was defined as Rutgeerts' score ≥ i2 have a duration of more tha...

Fournier gangrene is a very rare and a rapidly progressing, polymicrobial necrotizing faciitis or myonecrosis of the perineal, perianal and genital regions, with a high mortality rate. Infection is associated with superficial traum, urological and colorectal diseases and operations. The most commonly found bacteria are Escherichia coli followed by Bacteroides and streptococcal species. Diabetes...

Drug metabolism mostly occurs in the liver. Cytochrome P450 (CYP) is a drug-metabolizing enzyme that is responsible for many important drug metabolism reactions. Recently, the US FDA and EU EMA have suggested that CYP enzyme induction can be measured by both enzymatic activity and mRNA expression. However, these experiments are time-consuming and their inter-assay variability can lead to misint...

Ulcerative colitis (UC) is a chronic inflammation mainly affecting the colon mucosa. It predominantly occurs in younger patients. Until recently, the main goals in the treatment of UC were to temper the symptoms, such as diarrhea, pain, and weight loss, by using mesalazine and steroids. With newer medications, such as immunomodulators (thiopurines) and the biologics providing blockade of tumor ...

Background. The presence of ulcerative colitis (UC) with no bowel symptoms, as fever of unknown origin (FUO), is uncommon. Objective. To describe the case of an 80-year-old woman who presented with fever, with a history of UC under treatment with mesalazine. Case Presentation. She was admitted due to fever lasting for 12 days with no associated symptoms. Seven years earlier, she was diagnosed w...

OBJECTIVE The term "microscopic colitis" includes lymphocytic colitis (LC) and collagenous colitis, bearing common clinical presentation distinguishable only by histopathological examination of colonic biopsies. This study reports on demographic and clinical characteristics, and outcome of a cohort of patients with LC. METHODS Demographic, clinical and histopathological data were reviewed. Ev...
