Health-related quality of life in patients with newly diagnosed inflammatory bowel disease: an observational prospective cohort study (IBSEN III)

Purpose This unselected, population-based cohort study aimed to determine the level of health-related quality of life (HRQoL) in patients with Crohn’s disease (CD) and ulcerative colitis (UC) at the time of diagnosis compared with a reference population and identify the demographic factors, psychosocial measures, and disease activity markers associated with HRQoL. Methods Adult patients newly diagnosed with CD or UC were prospectively enrolled. HRQoL was measured using the Short Form 36 (SF-36) and Norwegian Inflammatory Bowel Disease Questionnaires. Clinical significance was assessed using Cohen’s d effect size and further compared with a Norwegian reference population. Associations between HRQoL and symptom scores, demographic factors, psychosocial measures, and disease activity markers were analyzed. Results Compared with the Norwegian reference population, patients with CD and UC reported significantly lower scores in all SF-36 dimensions, except for physical functioning. Cohen’s d effect sizes for men and women in all SF-36 dimensions were at least moderate, except for bodily pain and emotional role for men with UC and physical functioning for both sexes and diagnoses. In the multivariate regression analysis, depression subscale scores ≥ 8 on the Hospital Anxiety and Depression Scale, substantial fatigue, and high symptom scores were associated with reduced HRQoL. Conclusion Patients newly diagnosed with CD and UC reported statistically and clinically significantly lower scores in seven of the eight SF-36 dimensions than the reference population. Symptoms of depression, fatigue, and elevated symptom scores were associated with poorer HRQoL.publishedVersio

Fatigue in patients with newly diagnosed inflammatory bowel disease: Results from a prospective inception cohort, the IBSEN III study

Background and aims: Although fatigue is common in inflammatory bowel disease (IBD), its pathogenesis remains unclear. This study aimed to determine the prevalence of fatigue and its associated factors in a cohort of patients newly diagnosed with IBD. Methods: Patients ≥18 years were recruited from the Inflammatory Bowel Disease South-Eastern Norway (IBSEN III) study, a population-based, observational inception cohort. Fatigue was assessed using the Fatigue Questionnaire and compared with data from a Norwegian general population. Univariate and multivariate linear and logistic regression analyses were performed to evaluate the associations of total fatigue (TF) (continuous score) and substantial fatigue (SF) (dichotomized score ≥4) with sociodemographic, clinical, endoscopic, laboratory, and other relevant patient data. Results: In total, 983/1509 (65.1%) patients with complete fatigue data were included (ulcerative colitis (UC), 68.2%; Crohn's disease (CD), 31.8%). The prevalence of SF was higher in CD (69.6%) compared with UC (60.2%) (p<0.01), and in both diagnoses when compared to the general population (p<0.001).In the multivariate analyses, depressive symptoms, pain intensity, and sleep disturbances were associated with increased TF for both diagnoses. In addition, increased clinical disease activity and Mayo endoscopic score were significantly associated with TF in UC, whereas all disease-related variables were insignificant in CD. Similar findings were observed for SF, except regarding the Mayo endoscopic score. Conclusions: SF affects approximately two-thirds of patients newly diagnosed with IBD. Fatigue was associated with depressive symptoms, sleep disturbances, and increased pain intensity in both diagnoses, while clinical and endoscopic activity were associated factors only in UC.publishedVersio

Inflammatory bowel disease in South-Eastern Norway III (IBSEN III): a new population-based inception cohort study from South-Eastern Norway

Background and aim: Modern treatment strategies for inflammatory bowel disease (IBD) are postulated to change the natural disease course. Inception cohort studies are the gold standard for investigating such changes. We have initiated a new population-based inception cohort study; Inflammatory bowel disease in South Eastern Norway III (IBSEN III). In this article, we describe the study protocol and baseline characteristics of the cohort. Methods: IBSEN III is an ongoing, population-based observational inception cohort study with prospective follow-up. Adult and pediatric patients with suspected IBD in the South-Eastern Health Region of Norway (catchment area of 2.95 million inhabitants in 2017), during the 3-year period from 2017 to 2019, were eligible for inclusion. Comprehensive clinical, biochemical, endoscopic, demographic, and patient-reported data were collected at the time of diagnosis and throughout standardized follow-up. For a portion of the patients, extensive biological material was biobanked. Results: The study included 2168 patients, of whom 1779 were diagnosed with IBD (Crohn's disease: 626, ulcerative colitis: 1082, IBD unclassified: 71). In 124 patients, there were subtle findings indicative of, but not diagnostic for, IBD. The remaining 265 patients were classified as symptomatic non-IBD controls. Conclusion: We have included patients in a comprehensive population-based IBD cohort from a catchment population of 2.95 million, and a unique biobank with materials from newly diagnosed and treatment-naïve IBD patients and symptomatic non-IBD controls. We believe this cohort will add important knowledge about IBD in the years to come.publishedVersio

Low rate of local recurrence detection by rectoscopy in follow-up of rectal cancer

Aim: The main aim of this study was to examine the effectiveness of rectoscopy for detecting local recurrence of rectal cancer in patients following low anterior resection. Method: This was a retrospective study of 201 patients, who underwent low anterior resection for rectal or rectosigmoid cancer between 2007 and 2009 and who were followed up with rigid rectoscopy and imaging. A total of 91 patients were excluded from the analysis for various reasons, leaving 110 patients eligible for analysis. Results: A total of 613 rectoscopies were performed, and 48 biopsies taken. Six local recurrences were detected in the 110 patients, three of which were first detected by rectoscopy and three by CT. Two of the local recurrences were detected outside the follow‐up programme because of symptoms: one by rectoscopy and one by CT. Three of 613 (0.5%) rectoscopies led to detection of local recurrence. The sensitivity and specificity of rectoscopy to detect local recurrence was 0.50 and 0.93, respectively. Nineteen distant metastases were detected, and two patients had both local recurrence and distant metastasis. All local recurrences and distant metastases were detected within 48 months of surgery. Conclusion: Rigid rectoscopy is poor at detecting local recurrence. Only 3 out of 613 rectoscopies (0.5%) detected local recurrence. Due to extramural growth of some recurrences, the sensitivity is also very low. Based on our results, routine rectoscopy in the surveillance of asymptomatic patients cannot be recommended
