We report a case of a 63-year-old-man presenting with chronic diarrhea and weight loss while on olmesartan treatment for hypertension. Investigation showed multiple nutritional deficiencies associated with diffuse intestinal villous atrophy. Serologies for celiac disease were negative and other causes of villous atrophy were excluded. Olmesartan as a precipitant agent was suspected and withdrawn. Clinical improvement occurred in days with no need for other therapeutic measures. Follow-up at three months showed clinical remission and almost complete recovery of intestinal atrophy.Olmesartan is an angiotensin receptor blocker commonly prescribed for the management of hypertension. Spruelike enteropathy associated with this drug is a recently described entity with few cases reported. It presents with chronic diarrhea and intestinal villous atrophy and should be included in its differential diagnosis. This case intends to alert clinicians for the possibility of this event in a patient on treatment with this drug.
Background: Anaemia is the most common complication in patients with inflammatory bowel disease (IBD). This study aims to assess the prevalence of anaemia in IBD patients and to know its characteristics with regard to the main IBD clinical features. Methods: An observational cross-sectional multicentre study was conducted. We included all patients who had an appointment at the 15 participating centres during the period of 1 month, and who met the following selection criteria: age ≥18, diagnosis of IBD. Disease activity was evaluated by Harvey-Bradshaw Index (HBI) for Crohn's disease (CD), and by Simple Clinical Colitis Activity Index (SCCAI) for ulcerative colitis (UC). Results: One thousand three hundred and thirteen patients, were included: 54.8% female, mean age 42.8 (interquartile range (25th-75th): 31-53 years), 59% had a diagnosis of CD, 39% of UC and 2% IBD unclassified. The median follow-up since diagnosis was 7 years. The ongoing treatment was aminosalicylates (63.1%), corticosteroids (11.6%), immunomodulators (36.4%) and anti-tumour necrosis factor (27.3%). Anaemia was identified in 244 patients, representing a prevalence of 18.6% (95% CI 16.6-20.9). A majority of cases (90%) have mild/moderate anaemia (mean haemoglobin 11.3 ± 0.8 g/dl). Anaemia was significantly higher in females (p = 0.006), but there were no differences between CDs (19.1%) and UCs (17.7%; p = 0.688). Anaemia was more frequent in patients with active disease (HBI >4; SCCAI >2) than in those in clinical remission (33.6 vs. 15.6%, p < 0.001) and in patients on steroids (36.8%) vs. other treatments (p < 0.001). Only 47% of patients with anaemia were under any specific treatment (oral iron 67%; intravenous iron 41%). Conclusion: Anaemia was more frequent in patients with active disease and in those on corticosteroids. The treatment of anaemia still seems undervalued, whereas more than half of anaemic patients were not receiving any specific treatment and the use of oral iron prevails contrarily to current recommendations.
Background: Colonic diverticular bleeding is the most common cause of lower gastrointestinal bleeding. Risk factors related to severity and repeated bleeding episodes are not completely clearly defined.Objective: To characterize a Portuguese population hospitalized due to colonic diverticular bleeding and to identify the clinical predictors related to bleeding severity and rebleeding.Methods: Retrospective analysis of all hospitalized patients diagnosed with colonic diverticular bleeding from January 2008 to December 2013 at our institution. The main outcomes evaluated were bleeding severity, defined as any transfusion support requirements and/or signs of hemodynamic shock, and 1-year recurrence rate.Results: Seventy-four patients were included, with a mean age of 75.7 ± 9.5 years; the majority were male (62.2%). Thirty-six patients (48.6%) met the criteria for severe bleeding; four independent risk factors for severe diverticular bleeding were identified: low hemoglobin level at admission (≤ 11 g/dL; OR 18.8), older age (≥ 75 years; OR 4.7), bilateral diverticular location (OR 14.2) and chronic kidney disease (OR 5.6). The 1-year recurrence rate was 12.9%. We did not identify any independent risk factor for bleeding recurrence in this population.Conclusion: In this series, nearly half of the patients hospitalized with diverticular bleeding presented with severe bleeding. Patients with low hemoglobin levels, older age, bilateral diverticular location and chronic kidney disease had a significantly increased risk for severe diverticular bleeding. In addition, a small number of patients rebled within the first year after the index episode, although we could not identify independent risk factors associated with the recurrence of diverticular bleeding.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
