Housedustmite Allergy as the Cause of Eosinophilic Collitis: A Case Report

ABSTRACT

@#There are only few cases of Eosinophilic Collitis(EC) have been reported worldwide. The mechanism and aetiology of EC are still unclear. We describe a 35 years old man presented with chief complaints of gastrointestinal symptoms. In blood examination, his total IgE and specific IgE to house dust mites were very high. Colonoscopy was done and histological examination from biopsy specimens reported infiltration of lymphoplasmacytic cells and eosinophils, compatible with Eosinophilic colitis. The patient was treated with antihistamine and short course of antibiotics. He was been advised to avoid house dust mites. He was then remained asymptomatic. Our report suggests house dust mites allergy as the causes of EC. Combination of antihistamine, antibiotics and avoidance of house dust mites are helpful in treating EC in this particular case.
