[show abstract] [hide abstract]
ABSTRACT: The importance of fatigue in chronic disease has been increasingly recognized; however, little is known about fatigue in inflammatory bowel disease (IBD). The aim of the present study was to investigate the prevalence and severity of fatigue and the impact on health-related quality of life (HRQoL) in patients included in a population-based IBD cohort in the Netherlands. IBD patients, diagnosed between January 1st, 1991, and January 1st, 2003, were followed up for a median of 7.1 years. They completed a questionnaire, which included a disease activity score, the Multidimensional Fatigue Inventory (MFI-20), the Inflammatory Bowel Disease Questionnaire (IBDQ), and the Short Form health survey (SF-36). Hemoglobin levels were recorded. Data were available in 304 Crohn's disease (CD), 368 ulcerative colitis (UC), and 35 indeterminate colitis (IC) patients. During quiescent disease, the prevalence of fatigue was nearly 40%. MFI-20 and HRQoL scores were significantly worse in IBD patients having active disease. In a multivariate analysis, disease activity was positively related with the level of fatigue in both CD and UC. In UC, anemia influenced the general fatigue score independently of disease activity. Disease activity as well as fatigue were independently associated with an impaired IBDQ. In IBD, even in remission, fatigue is an important feature. Both in CD and in UC, fatigue determined HRQoL independently of disease activity or anemia. This implies that in IBD patients physicians need to be aware of fatigue in order to better understand its impact and to improve the HRQoL.Inflammatory Bowel Diseases 12/2010; 16(12):2137-47. · 4.86 Impact Factor -
Article: Clinical and economic outcomes in a population-based European cohort of 948 ulcerative colitis and Crohn's disease patients by Markov analysis.
[show abstract] [hide abstract]
ABSTRACT: Forecasting clinical and economic outcomes in ulcerative colitis (UC) and Crohn's disease (CD) patients is complex, but necessary. To determine: the frequency of treatment-classified clinical states; the probability of transition between states; and the economic outcomes. Newly diagnosed UC and CD patients, allocated into seven clinical states by medical and surgical treatments recorded in serial 3-month cycles, underwent Markov analysis. Over 10 years, 630 UC and 318 CD patients had 22,823 and 11,871 cycles. The most frequent clinical outcomes were medical/surgical remission (medication-free) and mild disease (on 5-aminosalicylates, antibiotics, topical corticosteroids), comprising 28% and 62% of UC cycles and 24% and 51% of CD cycles respectively. The probability of drug-response in patients receiving systemic corticosteroids/immunomodulators was 0.74 in UC, 0.66 in CD. Both diseases had similar likelihood of persistent drug-dependency or drug-refractoriness. Surgery was more probable in CD, 0.20, than UC, 0.08. In terms of economic outcomes, surgery was costlier in UC per cycle, but the outlay over 10 years was greater in CD. Drug-refractory UC and CD cases engendered high costs in the cohort. Most patients on 5-aminosalicylates, corticosteroids and immunomodulators had favourable clinical and economic outcomes over 10 years. Drug-refractory and surgical patients exhibited greater long-term expenses.Alimentary Pharmacology & Therapeutics 04/2010; 31(7):735-44. · 3.77 Impact Factor -
Article: Communication of information to patients with inflammatory bowel disease: A European Collaborative Study in a multinational prospective inception cohort.
[show abstract] [hide abstract]
ABSTRACT: Communication to patients of information about their disease has become increasingly important in modern medicine, and particularly with chronic nonfatal disorders like inflammatory bowel disease (IBD), but the subject is not adequately researched or understood. We studied the media and preferences for communication of information in a multi-national community-based inception cohort of European and Israeli patients with IBD and 10 years follow-up, using structured questionnaires categorizing demographics, disease status, current and preferred sources of information, use of electronic media, role of patients' associations, and satisfaction level. The 917 patients completing the questionnaire were derived from northern (60%) and southern (40%) countries. The mean age was 48.3 years (62% under 50 years); 51% were males; 67% had ulcerative colitis, 33% Crohn's disease. Sixty-six percent of patients designated the specialist as their primary source of information, 77% indicated satisfaction with their current information, and 65% reported not receiving information about medical treatment in the past year. Patient concerns were about new research into their illness (64%), medical treatments (58%), risks and complications (51%) and genetics (42%). Preferred sources of information were paper bulletin (76%), electronic media (30%) and international organization (79%). Diagnosis (ulcerative colitis or Crohn's disease), gender, education level and country impacted significantly on patients' choices. In providing health care information to patients with IBD their individual attitudes and preferences must be considered. There should be greater roles for IBD patients' associations and international IBD-research organizations, and an increasing use of electronic media.Journal of Crohn s and Colitis 09/2008; 2(3):226-32. · 2.57 Impact Factor -
Article: Dysplasia and cancer in inflammatory bowel disease 10 years after diagnosis: results of a population-based European collaborative follow-up study.
[show abstract] [hide abstract]
ABSTRACT: To determine dysplasia and cancer in the 1991-2004 European Collaborative Inflammatory Bowel Disease (EC-IBD) Study Group cohort. A patient questionnaire and a physician per patient form were completed for each of the 1,141 inflammatory bowel disease patients (776 ulcerative colitis/365 Crohn's disease) from 9 centers (7 countries) derived from the EC-IBD cohort. Rates of detection of intestinal cancer and dysplasia as well as extra-intestinal neoplasms were computed. Patient follow-up time was 10.3 +/- 0.8 (range 9.4-11) years. The mean age of the whole group of IBD patients was 37.8 +/- 11.3 (range 16-76) years. Thirty-eight patients (3.3%; 26 with ulcerative colitis/12 with Crohn's disease, 21 males/17 females, aged 61.3 +/- 13.4, range 33-77 years), were diagnosed with 42 cancers. Cancers occurred 5.4 +/- 3.3 (range 0-11) years after inflammatory bowel disease diagnosis. Colorectal cancer was diagnosed in 8 (1 Crohn's disease and 7 ulcerative colitis patients--0.3 and 0.9% of the Crohn's disease and ulcerative colitis cohort, respectively) of 38 patients and 30 cancers were extra-intestinal. Four of 38 patients (10.5%) were diagnosed as having 2 cancers and they were younger compared to patients with one cancer (p = 0.0008). There was a trend for a higher prevalence of intestinal cancer in the northern centers (0.9%) compared to southern centers (0.3%, p = NS). Southern centers had more cases of extra-intestinal cancer compared to northern centers (2 vs. 3.8%, p = 0.08). Ten patients (0.9%; 8 with ulcerative colitis/2 with Crohn's disease, 8 males, aged 62.3 +/- 14.1 years) had colorectal dysplasia. In the first decade of the EC-IBD Study Group cohort follow-up study, the prevalence of cancer was as expected with most patients having a single neoplasm and an extra-intestinal neoplasm. In northern centers there was a trend for more intestinal cancers, while in southern centers there was a trend for more extra-intestinal cancers compared to northern centers.Digestion 02/2007; 75(2-3):113-21. · 2.05 Impact Factor -

Article: Needle-knife sphincterotomy as a precut procedure: a retrospective evaluation of efficacy and complications.
[show abstract] [hide abstract]
ABSTRACT: Precut sphincterotomy remains a controversial means of gaining biliary access during endoscopic retrograde cholangiopancreatography (ERCP). This report is a retrospective evaluation of the use of needle-knife sphincterotomy as a precut procedure to achieve biliary access during ERCP. From November 1992 to August 1993, a total of 1071 ERCPs were performed at our institution. During this time, precut sphincterotomy was carried out in 180 patients, with complete follow-up obtained in 178 patients. The follow-up concentrated on the efficacy of the procedure and short-term complications. Cannulation of the common bile duct was achieved immediately after precut sphincterotomy in 88% of the patients, and during a second ERCP in an additional 11% of patients (total success rate 99%). There were no precut-related deaths. The complication rate of precut sphincterotomy was 21 in 178 (12%). Complications included bleeding in ten patients (5.5%), perforation in four patients (3%), pancreatitis in one patient (0.5%), and fever of unknown origin in six (3%) patients. All complications were managed conservatively. Precut sphincterotomy is a safe and highly effective method of gaining biliary access in patients in whom deep cannulation proves difficult or impossible and biliary access is considered essential.Endoscopy 06/1996; 28(4):334-9. · 5.21 Impact Factor
