We followed a population based cohort of patients with inflammatory bowel disease (IBD) from Olmsted County, Minnesota, in order to analyse long term survival and cause specific mortality. Material and
A total of 692 patients were followed for a median of 14 years. Standardised mortality ratios (SMRs, observed/expected deaths) were calculated for specific causes of death. Cox proportional hazards regression was used to determine if clinical variables were independently associated with mortality.
Fifty six of 314 Crohn's disease patients died compared with 46.0 expected (SMR 1.2 (95% confidence interval (CI) 0.9-1.6)), and 62 of 378 ulcerative colitis (UC) patients died compared with 79.2 expected (SMR 0.8 (95% CI 0.6-1.0)). Eighteen patients with Crohn's disease (32%) died from disease related complications, and 12 patients (19%) died from causes related to UC. In Crohn's disease, an increased risk of dying from non-malignant gastrointestinal causes (SMR 6.4 (95% CI 3.2-11.5)), gastrointestinal malignancies (SMR 4.7 (95% CI 1.7-10.2)), and chronic obstructive pulmonary disease (COPD) (SMR 3.5 (95% CI 1.3-7.5)) was observed. In UC, cardiovascular death was reduced (SMR 0.6 (95% CI 0.4-0.9)). Increased age at diagnosis and male sex were associated with mortality in both subtypes. In UC but not Crohn's disease, a diagnosis after 1980 was associated with decreased mortality.
In this population based study of IBD patients from North America, overall survival was similar to that expected in the US White population. Crohn's disease patients were at increased risk of dying from gastrointestinal disease and COPD whereas UC patients had a decreased risk of cardiovascular death.

    • "Colo-rectal cancer (CRC) has been recognized as a leading cause of long-term mortality in patients with IBD and causes 8% of all deaths in patients with UC [46]. Regular colonoscopic surveillance examinations with biopsies have been used to identify dysplasia, the earliest recognizable precursor of CRC and the most reliable marker of cancer risk in this population.

    ABSTRACT: This review summarizes diagnostic problems, challenges and advances in ulcerative colitis (UC). It emphasizes that, although histopathological examination plays a major role in the diagnosis and management of UC, it should always be interpreted in the context of clinical, endoscopic, and radiological findings. Accurate diagnosis requires knowledge of the classic morphological features of UC, as well as a number of atypical pathological presentations that may cause mis-classification of the disease process, either in resection or biopsy specimens. These atypical pathological presentations include rectal sparing and patchiness of disease at initial presentation of UC in pediatric patients or in the setting of medically treated UC, cecal or ascending colon inflammation in left-sided UC, and backwash ileitis in patients with severe ulcerative pancolitis. Loosely formed microgranulomas, with pale foamy histiocytes adjacent to a damaged crypt or eroded surface, should not be interpreted as evidence of Crohn's disease. Indeterminate colitis should only be used in colectomy specimens as a provisional pathological diagnosis. Patients with UC are at risk for the development of dysplasia and carcinoma; optimal outcomes in UC surveillance programs require familiarity with the diagnostic criteria and challenges relating to UC-associated dysplasia and malignancy. Colon biopsy from UC patients should always be evaluated for dysplasia based on cytological and architectural abnormalities. Accurate interpretation and classification of dysplasia in colon biopsy from UC patients as sporadic adenoma or UC-related dysplasia [flat, adenoma-like, or dysplasia-associated lesion or mass (DALM)] requires clinical and endoscopic correlation. Isolated polypoid dysplastic lesions are considered to be sporadic adenoma if occurring outside areas of histologically proven colitis, or adenoma-like dysplasia if occurring in the diseased segment. Recent data suggest that such lesions may be treated adequately by polypectomy in the absence of flat dysplasia in the patient. UC patients with DALM or flat high-grade dysplasia should be treated by colectomy because of the high probability of adenocarcinoma. The natural history of low-grade dysplasia (LGD) is more controversial: while multifocal LGD, particularly if detected at the time of initial endoscopic examination, is treated with colectomy, unifocal flat LGD detected during surveillance may be managed by close follow-up with increased surveillance. The surveillance interval and treatment options for UC patients with dysplasia are reviewed in detail.

    • "The remaining cases were confirmed by UGIE and histopathology (20%). Similar to other studies, the majority of UC patients in our series were between the second and fourth decade of life, whereas only a minor proportion (2%) was above the age of 65 compared to 12% in other reports, and only one (0.2%) CD patient was above the age of 65 compared to 9% in other series.[4445] The main age peak of our CD patients was between 14 and 28 years with a second smaller peak between 30 and 35 years.

    ABSTRACT: Background/Aim: Inflammatory bowel disease (IBD) is a chronic disease of unknown etiology and considered traditionally as a disease of the western world. Recently, rising trends have been observed in countries previously known to have a low prevalence and incidence. The aim of this study is to collect epidemiological data on IBD outpatients and to add data from the Kingdom of Saudi Arabia (KSA) to the available IBD literature. Patients and Methods: The medical records of 693 Saudi patients with IBD over a period of 17 years, between 1993 and 2009, were reviewed. The demographic and clinical data and methods of diagnosis were retrieved. Results: The total number of patients in this cohort was 693. It constituted 238 (34.3%) ulcerative colitis (UC) and 455 (65.7%) Crohn's disease (CD) patients. UC was steady throughout the years, whereas only 1.2 CD patients were diagnosed per year in the first 11 years, and 73.7 per year in the last six years. The median age of UC patients was 34 years, ranging from 10 to 80 years with a peak between 21 and 40 years and in CD it was 27 years, ranging from 11 to 73 years with a peak between 11 and 30 years. There was a male preponderance of 1.5:1 and 2:1, respectively. The rest of the data is discussed in this study. Conclusion: IBD is no longer a rare disease in KSA. UC is in a steady state, whereas CD is increasing significantly and far outnumbering UC.

    ABSTRACT: Background Ulcerative colitis is an inflammatory chronic disease which is believed to be a multi organ condition. The prevalence of ulcerative colitis is reportedly increasing in Iran presenting with the same clinical characteristics as in developing countries. Pulmonary manifestations of ulcerative colitis are increasingly reported. In this study, we investigated the incidence of bronchial hyper-responsiveness (BHR) in ulcerative colitis (UC) patients. Materials and Methods Fifty-one UC patients with definite diagnosis referred to Shariati Hospital, Tehran, Iran, were selected to be evaluated with methacholine challenge test from October 2010 to October 2011. Patients were compared for their methacholine test outcome and its association with age, sex, diagnosis time, and disease activity. Results The median age was 41 (range 15 to 65) years. The median time of diagnosis was 7 (range <1 to 16) years. Forty-five percent were females, 18% had active disease and 13% had comorbidity. Nine percent of patients with UC had abnormal PFT in our study. Three cases (5%) had bronchial hyper-responsiveness that was not correlated with sex, age, time of diagnosis, or disease activity. Conclusion A small number of ulcerative colitis patients in our study had disturbed pulmonary function test which is in concord with the findings of other studies. However, higher rates of bronchial hyper-responsiveness have been reported in other studies. Confounding factors like cigarette smoking and medications, which were negative or minimal in our study, may influence the results.
