[Idiopathic thrombocytopenic purpura and food allergy: a study on possible correlations].
Eight children affected by idiopathic chronic thrombocytopenia were studied for history of food allergy, anti-platelet antibodies, total IgE, prick test for food antigens, AGA and EMA. They were free of treatment for thrombocytopenia since at least six months before. Three children had in the first year of life intolerance to cow's milk proteins with atopic dermatitis and/or poor growth. None had AGA or EMA positivity. 6/8 had positivity for anti-platelet antibodies. A 15-days oligoantigenic diet was instituted in all of them. Platelet count was unaffected in all but one, in which a sharp increase was noted (from 19x 10(9)/l. to 150x 10(9)/l.). He was a 12-year-old boy with a previous history of cow's milk intolerance and actual skin prick test positivity for casein and lactoglobulin. A one-year follow up for this case was instituted and he was put on two further 15-days periods of oligoantigenic diet, but no change in platelet count was noted any more.


CONCLUSIONS
we were not able to correlate chronic thrombocytopenia to food allergy.
