Abstract
Nutritional status of 86 patients with dermatitis herpetiformis (DH) was defined by anthropometric measurements and hematological and biochemical laboratory tests to establish prevalence of malabsorption and malnutrition. Anthropometric measurements in DH patients were comparable to normal control patients. Four individuals were of short stature; two had had diarrhea and failed to thrive in childhood. Abnormalities attributable to nutritional deficiency were detected in only 6 of the 86, whereas drug-associated hematological or biochemical changes were present in 36 of 55 subjects treated with dapsone or sulfapyridine. Twenty patients had hemolytic anemia or macrocytosis related to drug therapy. Only two had anemias attributable to malabsorption; one was iron deficient, the other folate deficient. Two other patients were mildly Fe deficient and two had slight folate deficiency; they lacked other stigmata of malabsorption. Drug-induced hematological and biochemical abnormalities were more common than changes that suggest nutritional disease, even though most DH patients had an enteropathy at presentation.
