Outcome of Ulcerative Colitis 20 Years after Diagnosis in a Prospective Population-based Inception Cohort from South-Eastern Norway, the IBSEN Study.

BACKGROUND AND AIMS: The long-term course of ulcerative colitis [UC] is difficult to predict. Mortality, colectomy, cancer, and hospitalisation represent hard outcomes of disease. Moreover, knowledge on the risk of relapses and need for potent medication add important information about living with UC. We aimed to evaluate the course and prognosis of UC during the first 20 years after diagnosis, and to identify early prognostic risk factors. METHODS: From 1990 to 1994, a population-based inception cohort of patients with inflammatory bowel disease was enrolled in South-Eastern Norway. A systematic follow-up [FU] was conducted at 1,5, 10, and 20 years after diagnosis. Clinical outcomes were recorded continuously, and possible relationships between early disease characteristics and outcomes were analysed using multiple regression analysis. RESULTS: Among 519 UC patients, 119 died, 60 were lost to FU, and 340 were included in the FU cohort. The 20-year cumulative risk of colectomy was 13.0% (95% confidence interval [CI] [11.4-14.6]). Extensive colitis at diagnosis was independently associated with an increased risk of colectomy compared with proctitis (hazard ratio [HR] = 2].8, 95% CI [1.3-6.1]). In contrast, mucosal healing at 1-year FU was independently associated with reduced risk of colectomy [HR = 0.4, 95% CI [0.2-0.8]), and inversely associated with subsequent risk of relapse [adjusted HR = 0.5, 95% CI [0.3-0.7]). CONCLUSIONS: The overall risk of colectomy in our cohort was lower than expected from previous studies, although considerable for patients with extensive colitis at diagnosis. Early mucosal healing was associated with better disease outcomes 20 years after diagnosis.

Routine diagnosis of intestinal tuberculosis and Crohn's disease in Southern India.

AIM: To investigate whether routinely measured clinical variables could aid in differentiating intestinal tuberculosis (ITB) from Crohn's disease (CD). METHODS: ITB and CD patients were prospectively included at four South Indian medical centres from October 2009 to July 2012. Routine investigations included case history, physical examination, blood biochemistry, ileocolonoscopy and histopathological examination of biopsies. Patients were followed-up after 2 and 6 mo of treatment. The diagnosis of ITB or CD was re-evaluated after 2 mo of antituberculous chemotherapy or immune suppressive therapy respectively, based on improvement in signs, symptoms and laboratory variables. This study was considered to be an exploratory analysis. Clinical, endoscopic and histopathological features recorded at the time of inclusion were subject to univariate analyses. Disease variables with sufficient number of recordings and P < 0.05 were entered into logistic regression models, adjusted for known confounders. Finally, we calculated the odds ratios with respective confidence intervals for variables associated with either ITB or CD. RESULTS: This study included 38 ITB and 37 CD patients. Overall, ITB patients had the lowest body mass index (19.6 vs 22.7, P = 0.01) and more commonly reported weight loss (73% vs 38%, P < 0.01), watery diarrhoea (64% vs 33%, P = 0.01) and rural domicile (58% vs 35%, P < 0.05). Endoscopy typically showed mucosal nodularity (17/31 vs 2/37, P < 0.01) and histopathology more frequently showed granulomas (10/30 vs 2/35, P < 0.01). The CD patients more frequently reported malaise (87% vs 64%, P = 0.03), nausea (84% vs 56%, P = 0.01), pain in the right lower abdominal quadrant on examination (90% vs 54%, P < 0.01) and urban domicile (65% vs 42%, P < 0.05). In CD, endoscopy typically showed involvement of multiple intestinal segments (27/37 vs 9/31, P < 0.01). Using logistic regression analysis we found weight loss and nodularity of the mucosa were independently associated with ITB, with adjusted odds ratios of 8.6 (95%CI: 2.1-35.6) and 18.9 (95%CI: 3.5-102.8) respectively. Right lower abdominal quadrant pain on examination and involvement of ≥ 3 intestinal segments were independently associated with CD with adjusted odds ratios of 10.1 (95%CI: 2.0-51.3) and 5.9 (95%CI: 1.7-20.6), respectively. CONCLUSION: Weight loss and mucosal nodularity were associated with ITB. Abdominal pain and excessive intestinal involvement were associated with CD. ITB and CD were equally common.

Measuring health-related quality of life in non-complicated diabetes patients may be an effective parameter to assess patients at risk of a more serious disease course: a cross-sectional study of two diabetes outpatient groups.

AIM: To describe health-related quality of life in diabetes outpatients and investigate the impact of diabetic foot ulcers, by comparing a group of patients with and without diabetic foot ulcers complications. Secondary to study the impact of sociodemographic and clinical variables in the two groups. DESIGN: Cross-sectional study. METHODS: The study involved 130 diabetes outpatients and 127 diabetic foot ulcers patients. Health-related quality of life was measured with the generic questionnaire Short Form-36, consisting of eight dimensional scores. All scores were adjusted for differences in age and gender (estimated marginal means). Differences were compared with anova calculations, by the use of Predictive Analytics Software, PASW (version 17.0). RESULTS: This study confirms that health-related quality of life differs significantly between disease subgroups when measured with Short Form-36. Diabetic foot ulcers had a major negative impact on 7/8 subscales on the Short Form-36 compared to the diabetes outpatients group. health-related quality of life decreased with increasing amount of complications and comorbidity in the diabetes outpatients group, with cardiovascular complications being the most pronounced predictor of lower health-related quality of life scores. CONCLUSION: Patients who have developed diabetic foot ulcers reports much poorer health-related quality of life than compared to diabetes outpatients. Factors linked to the development of late complications were not detected in the diabetic foot ulcers group, such as cardiovascular comorbidity and neuropathy. RELEVANCE TO CLINICAL PRACTICE: Health-related quality of life measurement in early stages of disease may detect patients at risk of a more serious disease course and who consequently are in need of a more intensive follow-up.
