title: Impact of functional bowel symptoms on quality of life and fatigue in quiescent Crohn disease and irritable bowel syndrome.
abstract: BACKGROUND
  Patients with irritable bowel syndrome (IBS) and Crohn disease (CD) have impaired quality of life (Qol) associated with fatigue. Whether IBS-like symptoms have a similar impact on Qol and fatigue in quiescent CD than in IBS is currently unknown. Our aims were (i) to evaluate the prevalence of IBS-like symptoms in quiescent CD and (ii) to compare the impact of IBS-like symptoms on Qol and fatigue in both diseases.
  
  
  METHODS
  A total of 92 quiescent CD, 40 IBS and 20 healthy subjects similar in age were included prospectively in five French academic centers. IBS symptoms were evaluated through the Rome III criteria. The severity of IBS symptoms, Qol, fatigue, depression and anxiety was measured using questionnaires (Francis Score, Likert scales, Fatigue Impact Scale, short-form Beck and Hospital Anxiety and Depression Scale).
  
  
  RESULTS
  Irritable bowel syndrome-like symptoms were found in 42/92 (45.6%) patients with quiescent CD. The presence of IBS-like symptoms was associated with significant more profound alterations of Qol, high scores of fatigue, depression, but similar levels of anxiety. Compared to CD patients with IBS-like symptoms, IBS patients had more severe gastrointestinal symptoms and alterations of Qol, but similar scores of fatigue, depression and anxiety. In quiescent CD patients, fatigue was independently associated with the presence of IBS-like symptoms (OR = 1.018, 95% CI: 1.002-1.034, P = 0.02).
  
  
  CONCLUSIONS
  The prevalence of IBS-like symptoms is elevated in quiescent CD. The presence of IBS-like symptoms in quiescent CD is probably associated with the range of fatigue/depression disorders. The mechanism underlying the occurrence of IBS-like symptoms in quiescent CD needs to be further explored.
