Abstract: OBJECTIVE: An exact diagnosis of inflammatory bowel disease (IBD) and further subclassification may be difficult even after clinical, radiological and histological examinations. A correct subclassification is important for the success of both medical and surgical therapeutic strategies, but there is a dearth of information available on the frequency of changes in diagnosis in population-based studies. The objective of this work was prospectively to re-evaluate the diagnosis in an unselected cohort of IBD patients during the first five years after the initial diagnosis. MATERIAL AND METHODS: Patients classified as IBD or possible IBD in the period 1990-94 (the IBSEN cohort) had their diagnosis re-evaluated after 1 and 5 years. Initially, the patients were classified as ulcerative colitis (UC), Crohn's disease (CD), indeterminate colitis (IC) or possible IBD. At the 5-year visit, patients were classified as UC, CD or non-IBD. RESULTS: A total of 843 patients (518 UC, 221 CD, 40 IC and 64 possible IBD) were identified. Clinical information was available for 94% of the patients who survived after 5 years. A change in diagnosis was found in 9% of the patients initially classified as UC or CD. A change to non-IBD was more frequent than a change between UC and CD. A large proportion of patients initially classified as IC or possible IBD were diagnosed as non-IBD after 5 years (22.5% versus 50%). When IBD was confirmed in these groups, UC was more frequent than CD. Two changes in diagnosis during follow-up were observed in 2.8% of the patients; this was more frequent in patients initially classified as IC or possible IBD. CONCLUSIONS: There are obvious diagnostic problems in a minority of patients with IBD; a systematic follow-up is therefore important in these patients.

Abstract: BACKGROUND: The majority of studies concerning the clinical course and prognosis in ulcerative colitis (UC) are old, retrospective in design, or hospital based. We aimed to identify clinical course and prognosis in a prospective, population-based follow-up study MATERIALS AND METHODS: Patients diagnosed with inflammatory bowel disease (IBD) or possible IBD in southeastern Norway during the period 1990-1994 were followed prospectively for 5 years. The evaluation at 5 years included an interview, clinical examination, laboratory tests, and colonoscopy. RESULTS: Of 843 patients diagnosed with IBD, 454 patients who had definite UC and for whom there were sufficient data for analysis were alive 5 years after inclusion in the study. The frequency of colectomy in this population was 7.5%. Forty-one percent of the patients were not taking any kind of medication for IBD at 5 years. Of the patients initially diagnosed with proctitis, 28% had progressed during the observation period, 10% to extensive colitis. The majority of the patients (57%) had no intestinal symptoms at 5 years, and only a minority (7%) had symptoms that interfered with everyday activities. Among the patients who underwent colonoscopy at the 5-year visit, symptoms were frequently reported in patients without macroscopic inflammation (44%). A relapse-free course was observed in 22% of the patients. A decrease in symptoms during the follow-up period was the most frequent course taken by the disease and was observed in 59% of the cases. The extent of disease was unrelated to symptoms at 5 years and also to relapse rate and course of disease during the 5-year period. CONCLUSIONS: The disease course and prognosis of UC appears better than previously described in the literature. The frequency of surgery was low, and only a minority of the patients had symptoms that interfered with their everyday activities 5 years after diagnosis.

Abstract: BACKGROUND: The goal of this study was to determine the rate of work disability, unemployment, and sick leave in an unselected inflammatory bowel disease (IBD) cohort and to measure the effect of working status and disability on the patient's health-related quality of life (HRQOL). MATERIALS AND METHODS: All eligible patients were clinically examined and interviewed at the 5-year follow-up visit. In addition, they completed the 2 HRQOL questionnaires, the Short Form-36 Health Survey (SF-36) and the Inflammatory Bowel Disease Questionnaire validated for use in Norway (N-IBDQ). Data regarding sick leave, unemployment, and disability pension (DP) also were collected. RESULTS: All together, 495 patients were or had been in the workforce during the 5-year follow-up period since diagnosis. Forty-two patients (8.5%) were on DP compared with 8.8% in the background population. Women with Crohn's disease (CD) had the highest probability of receiving DP (24.6%). A total of 58 patients (11.7%) reported they were unemployed at 5 years. This was equally distributed between men and women but was more frequent in patients with ulcerative colitis. Sick leave for all causes was reported in 47% with ulcerative colitis and 53% with CD, whereas IBD-related sick leave was reported in 18% and 23%, respectively. A majority (75%) had been sick <4 weeks, and a relatively small number of patients (25%) contributed to a large number of the total sick leave days. Both unemployment and DP reduced HRQOL scores, but the most pronounced effect on HRQOL was found in patients reporting IBD-related sick leave, measured with SF-36 and N-IBDQ. The observed differences also were highly clinically significant. Multiple regression analysis confirmed that IBD-related sick leave was the independent variable with the strongest association to the observed reduction in HRQOL scores. CONCLUSIONS: Unemployment or sick leave is more common in IBD patients than in the Norwegian background population. The number of patients receiving DP is significantly increased in women with CD but not in the other patient groups. Unemployment, sick leave, and DP are related to the patient's HRQOL in a negative way, but this effect is most pronounced in patients reporting IBD-related sick leave.

Abstract: OBJECTIVES: We assessed health-related quality of life (HRQOL) on the basis of a cross-sectional design in a population-based cohort of inflammatory bowel disease patients followed prospectively for 5 years after diagnosis. The aim was to investigate the influence of the course of disease, drug therapy, and relapse pattern on the patients' HRQOL. METHODS: All patients completed the validated Norwegian version of the Inflammatory Bowel Disease Questionnaire (N-IBDQ). We present data from 497 patients, 328 with ulcerative colitis and 169 with Crohn's disease. The mean age was 43.3 years, and 48% were female. RESULTS: Crohn's disease patients treated with systemic steroids or azathioprine had a statistically significant reduction in the N-IBDQ total score compared with non-users. Patients with a more severe disease pattern had a lower N-IBDQ total score. Patients reporting a relapse during the observation period had a significantly lower total score and dimension scores than patients without relapse in both diagnostic groups, and likewise there was a statistically significant decrease in N-IBDQ total score for those with extra-intestinal manifestations compared with those without. A multiple linear regression model showed that the number of relapses during the preceding year in ulcerative colitis, and sex (female gender) in Crohn's disease were the strongest predictor of a reduction in N-IBDQ total score. CONCLUSION: Treatment with systemic steroids or immunosuppressive drugs, a relapsing disease and the presence of extra-intestinal manifestations were associated with a clinically significant reduction in the patients' HRQOL.

Abstract: BACKGROUND: Health-related quality of life (HRQOL) has become an important tool in evaluating patient satisfaction in inflammatory bowel disease (IBD). So far, few prospective follow-up studies have been done to identify variables that influence HRQOL. We aimed to identify demographic and clinical variables that influence HRQOL 5 years after diagnosis in patients with ulcerative colitis (UC) or Crohn disease (CD) included in a prospective follow-up study from 1990 to 1994 (the IBSEN study). METHODS: All patients completed the Inflammatory Bowel Disease Questionnaire (IBDQ), a disease-specific quality-of-life questionnaire translated into Norwegian and validated. We present data from 497 patients (328 UC patients and 169 CD patients, mean age 43.3 years, 48% female). The impact of age, gender, smoking, symptom severity, disease distribution, rheumatic symptoms and surgery on IBD patients' HRQOL was analysed. RESULTS: Women had a reduction in IBDQ total score of 10 points compared to men, CD patients had a reduction of 7.5 compared to UC patients. The patients with moderate/severe symptoms had a 50 points lower score than the patients without symptoms. The patients with rheumatic symptoms had a 10 points lower total score than the patients without these symptoms. All differences were statistically significant. The multiple regression analysis showed that symptom severity, rheumatic symptoms and female gender were the strongest predictors of reduction in HRQOL for both diagnosis groups. CONCLUSION: IBD symptoms, rheumatic symptoms and female gender have a significant influence on patients' HRQOL as measured by IBDQ. This was confirmed by the regression analysis.
