Interrelationship between biliary dyskinesia and chronic urticaria, chronic eczema and atopic dermatitis

Interrelationships between biliary dyskinesia and chronic urticaria, chronic eczema and atopic dermatitis have been studied in 210 biliary dyskinesia patients and 60 normal subjects. Incidences of chronic urticaria, chronic eczema and atopic dermatitis were found more frequently in biliary dyskinesia patients than normal subjects. Skin symptoms of these chronic urticaria, chronic eczema and atopic dermatitis cases showed significant normalization with improved gallbladder contraction rate. COMT inhibitor therapy and fat restriction were more effective for the skin symptoms and for prolonging the interval before recidivation or exacerbation of these allergic diseases than conservative therapy.
