Allergen Specific Serum IgE Antibody in Patients with Intestinal Polyp and Irritable Bowel Syndrome:A Clinical Analysis / 胃肠病学

ABSTRACT

Background:Eosinophilic gastroenteritis is the most common gastrointestinal allergic disease,however,allergy also accounts for some gastrointestinal functional disorders. The correlation between allergic factor and intestinal polyp is not clarified. Aims:To investigate the correlation of allergic factor with intestinal polyp and irritable bowel syndrome(IBS). Methods:Ninety-five inpatients including 60 cases of intestinal polyp and 35 cases of IBS admitted from May 2012 to April 2014 were recruited;95 healthy volunteers were served as controls. Serum samples were collected to test specific IgE antibodies derived from 20 common inhalant and alimentary allergens by EUROIMMUN blotting test. Results:The positivity rates of allergen specific serum IgE antibodies in intestinal polyp group,IBS group and both two groups were 56. 67% ,74. 29% and 63. 16% ,respectively,all were significantly higher than that in control group(6. 32% ,P all 0. 05). In all the 20 allergens tested,the positivity rates of Dermatophagoides,roach,crab,sea fish,freshwater fish,shrimp,and egg albumin specific serum IgE antibodies were significantly higher in patients group than in control group( P < 0. 05), especially the crab,see fish and Dermatophagoides specific IgE antibodies. Conclusions:Allergic factor might have some association with intestinal polyp and IBS.
