Inflammatory bowel disease (IBD) is a chronic and life-threating inflammatory disease of gastroenteric tissue characterized by episodes of intestinal inflammation. The pathogenesis of IBD is complex. Recent studies have greatly improved our knowledge of the pathophysiology of IBD, leading to great advances in the treatment as well as diagnosis of IBD. In this review, we have systemically reviewed the pathogenesis of IBD and highlighted recent advances in host genetic factors, gut microbiota, and environmental factors and, especially, in abnormal innate and adaptive immune responses and their interactions, which may hold the keys to identify novel predictive or prognostic biomarkers and develop new therapies.

Previous studies have reported a high prevalence of inflammatory bowel disease among the relatives, and especially siblings, of patients with Crohn's disease or ulcerative colitis. This high familial prevalence of Crohn's disease and ulcerative colitis suggests that genetic factors could play a role in the development of these disorders. The present study attempted to assess the relative risk for relatives of Crohn's disease and ulcerative colitis patients based on data provided by 1015 questionnaires completed by patients in northern Alberta. A Mx22x2 test among relatives was performed on the diseased versus normal data for each diagnosis to determine if significant differences existed. The prevalence for mothers and sisters was the highest of the relative groups for Crohn's disease ( 6430 of 105and 4670 of 105, respectively). Female relatives tended to have twice the prevalence of their male counterparts. There were differences between mother, daughter and sister prevalence rates for Crohn's disease. These results support the hypothesis that a genetic predisposition in families combined with possible environmental and lifestyle influences determine the relative risk of developing Crohn's disease and ulcerative colitis.

Inflammatory bowel disease (IBD) is a type of chronic relapsing inflammatory disease. The pathogenesis of IBD is still unclear, which may involve environmental factors, genetic factors, intestinal microbiota disorder, and abnormal immune responses. Exosomes (30–150 nm) are found in various body fluids, including blood, saliva, urine, and cerebrospinal fluid. Exosomes mediate intercellular communication and regulate cell biological activity by carrying non-coding RNAs, proteins, and lipids. There is evidence that exosomes are involved in the pathogenesis of IBD. In view of the important roles of exosomes in the pathogenesis of IBD, this work systematically reviews the latest research progress of exosomes in IBD, especially the roles of exosomes as non-coding RNA delivery systems in the pathogenesis of IBD, including a disordered immune response, barrier function, and intestinal microbiota. The review will help to clarify the pathogenesis of IBD and explore new diagnostic markers and therapeutic targets for patients with IBD.

Inflammatory bowel disease is a group of inflammatory disorders of unknown etiology. Various genetic factors, mucosal immune response, inappropriate activation of immune system driven by the presence of various luminal flora and epithelial defects have been postulated. Crohn disease and Ulcerative colitis are the two most common inflammatory bowel diseases. Since, specific clinical laboratory features are lacking which may help in establishing a diagnosis histopathological diagnosis remains the gold standard. This review highlights the known hypothesis regarding the etiopathogenesis of these two diseases and also describes pertinent histological features.Journal of Pathology of Nepal (2015) Vol. 5, 756-765
