简要总结
Introduction:
Helicobacter pylori has been linked to a variety of gastric and extra gastric diseases. Chronic infection with H. pylori causes histologically evident gastritis in all colonized individuals and is the predominant risk factor for gastric and duodenal ulcers as well as gastric adenocarcinoma. However, increasingly robust experimental and epidemiological evidence suggests that H. pylori may at the same time be beneficial to its carriers, as it efficiently prevents allergic disorders and chronic inflammatory conditions .
Inflammatory bowel disease (IBD) is characterized by chronic, nonspecific intestinal inflammation with an unexplained pathology and an alternating relapsing and remitting clinical progression. IBD is divided into two subtypes: ulcerative colitis (UC) and Crohn's disease (CD). Most studies in the IBD field attribute its etiology to the complex interactions among immune dysfunction, genetic susceptibility of the host, and environmental risk factors.
Since the twenty-first century, improving hygienic conditions and socioeconomic status have reduced the H. pylori infection rate and this trend has concurrently been accompanied by an increased IBD incidence in most countries Numerous studies have reported a lower H. pylori infection rate in patients with CD and/or UC than in non-IBD control individuals. although a small number of studies showed no significant association .Recently, emerging epidemiologic studies and animal experiments revealed an inverse correlation between H. pylori infection and IBD onset, suggesting that H. pylori colonization exerts a special protective effect on autoimmune diseases
observation Cross sectional study will be conducted at assuit university hospitals on all patients with inflammatory disease to detect the prevalence of helicobacter pylori among them .Then the examined patients will be divided in to two group receiving the same medication group A : inflammatory bowel disease patient with H.PYLORI group B: inflammatory bowel disease Patient without H.PYLORI longitudinal study will be conducted to both group to study the clinical outcomes in both group .
