Recurrent urticaria and reduced diamine oxidase activity

Abstract: An abnormal metabolism of histamine has been suspected in urticaria and the role of diamine oxidase (DAO: histaminase) is therefore of interest. We have studied DAO activity in plasma and jejunal biopsy material and have measured the post-heparin DAO release in 11 control subjects and nine with recurrent urticaria, three of whom had had concurrent episodes of abdominal pain. Two of the nine urticaria subjects had only a minimal rise in plasma DAO activity after heparin, three had a response which was at the lo… Show more

“…On the one hand, the patients' clinical presentation can resemble other food intolerances or allergy and is usually diagnosed under the umbrella of irritable bowel syndrome (IBS) 2, 7. On the other hand, histamine intolerance is also characterized by extra‐intestinal symptoms such as headache,15 pruritus,16 urticaria,17 atopic eczema,18 cardiac arrhythmia19 and asthma13, 14 that exceed the diagnosis of IBS. As both the aetiology and the course of histamine intolerance are not sufficiently investigated, the knowledge and treatment in the medical field are not always uniform.…”

“…21 Diamine oxidase is the main enzyme involved in histamine degradation, with predominant activity in the intestinal mucosa. 21 Alcohol and some drugs [imipenem, dobutamine, pancuronium, pentamidine, verapamil, isoniazid, clavulanic acid, dihydralazine, chloroquine, acetylcysteine, metoclopramide and cefuroxime] can reduce the activity of this enzyme and determine greater sensitivity to histamine-rich or histamine-producing foods [fish (tuna, sardine, anchovy), cheese (parmesan, Emmenthal, Gouda), salami, sausage, certain vegetables (tomato), wine and beers]. 21 Several experiments have demonstrated a diamine oxidase deficiency in the enterocytes of patients with chronic or recurrent urticaria 21 (grade of recommendation C).…”

“…The enzyme diamine oxidase (DAO), which is a major catabolic enzyme for histamine, is found in highest concentration in the ileal mucosa (Lessof et al, 1990). DAO is thought to be involved in the possible inhibition of colonic mucosal proliferation (Kusche et al, 1988).…”
