Paracetamol anaphylaxis is a very rare event, with only a few cases described in literature and even less reported in children. We report the case of a 15-year-old boy, referred to Immunoallergy Department due to four reproducible episodes of anaphylaxis after paracetamol administration, since the age of 8 years. The most severe episode occurred at […]

A patient monosensitized to plane pollen is described. On ISAC 103 the patients showed IgE reactivity to both Pla a 1 and Pla a 2, but on immunoblot analysis the serum showed a single IgE reactivity at about 50 kDa allergen.
The prevalence of food allergy and anaphylaxis in children is reported to be increasing in recent years. Evidence suggests that exposure to large doses of antigen favors the maintenance of tolerance. We report a case of sudden loss of cow’s milk tolerance in a long-sensitized girl with celiac disease after a short period of milkless […]
A 39-years-old man afferred to our hospital for a fever lasting for more than 6 months, without abnormalities at physical examination (in particular no skin alterations); a recent laboratory and instrumental investigation was ineffective and so a fever of unknown origin (FUO) was diagnosed. Since he reported an history of infantile mastocytosis (usually auto-resolving) we […]
Angioedema due to C1 – inhibitor deficiency may be hereditary (HAE) or acquired (AAE). AAE is a very rare condition, whose prevalence is possibly underestimated, as it is often unrecognized. AAE usually occurs after the fourth decade of life, and it is commonly associated to an underlying disease, mainly lymphoproliferative disorders. We report a 74-years […]
A case of mono-sensitization to a heat- and pepsin-stable allergen in zucchini is described.
A case of rice allergy in a patient with baker’s asthma is described. On ISAC 112 IgE reactivity to wheat á amylase/trypsin inhibitor (nTri a aA_TI) and Lipid Tranfer Protein (rTri a 14) was found.We hypothesize that the reaction by oral ingestion was elicited by homologous molecules in rice seeds.
We report the case of a 18-year old male who developed intraoperative anaphylaxis. The presence of specific IgE to ranitidine was documented. This case confirms the possibility of anaphylaxis at first exposure.
Women with inherited thrombophilia and recurrent miscarriage might benefit from preconceptional antiagreggation with low-dose acetylsalicylic acid (ASA), but concerns about severe adverse reactions may prevent physicians from performing this treatment in patients with ASA hypersensitivity.We report the first known case of ASA desensitization in a 41-year-old woman with inherited thrombophilia, who had homozygosity(4G/4G polymorphism) of […]

In literature it has been described a high risk of systemic reaction after blood-sucking Dyptera bites, like mosquitoes and horsefly, in people sensitive to hymenoptera. A 51 year old man, allergic to hymenoptera venom and with a history of IV reaction after Mueller , who has been treated with Vespula sp. ITS for the last […]
