Practice parameters for sublingual immunotherapy.

The efficacy and safety of sublingual immunotherapy (SLIT) are currently supported by clinical trials, meta-analysis and post-marketing surveys. Practice parameters for clinical use of SLIT are proposed here by a panel of Italian specialists, with reference to evidence based criteria. Indications to SLIT include allergic rhinoconjunctivitis, asthma, and isolated conjunctivitis (strength of recommendation: grade A). As to severity of the disease, SLIT is indicated in moderate/severe intermittent rhinitis, persistent rhinitis and mild to moderate asthma (grade D). SLIT may be safely prescribed also in children aged three to five years (grade B), and its use in subjects aged more than 60 years is not prevented when the indications and contraindication are ascertained (grade D). The choice of the allergen to be employed for SLIT should be made in accordance with the combination of clinical history and results of skin prick tests (grade D). Polysensitisation, i.e. the occurrence of multiple positive response does not exclude SLIT, which may be done with the clinically most important allergens (grade D). As to practical administration, co-seasonal, pre co-seasonal, and continuous schedules are available, being the latter recommended for perennial allergens or for pollens with particularly prolonged pollination, such as Parietaria (grade D). For pollens with relatively short pollination, such as grasses and trees (cypress, birch, alder, hazelnut, olive) the pre co-seasonal and perennial schedules are preferred (grade C). The build-up phases suggested by manufacturers can be safely used (grade A), but they can be modified according to the patient's tolerance (grade C). A duration of SLIT of 3-5 years is recommended to ensure a long-lasting clinical effect after the treatment has been terminated (grade C).

Anaphylactic shock to Argas reflexus bite.

Anaphylaxis is a severe, life-threatening allergic reaction, affecting both children and adults. The occurrence of anaphylaxis is not as rare as generally believed (1.21% to 15.04% of the US population). Often the cause of this reaction remain unknown, mainly due to the difficulty in defining the outbreaking causes. Herein, we describe an interesting case of a patient, who developed an anaphylactic reaction after the bite of a pigeon tick. During the last 2 years, in wintertime, the patient often came to the emergency room for general rash and swelling, hypotension and tachycardia preceded by itching and general distress. Notably, the symptoms manifested themselves as night fell. In two particular occasions the patient reached the hospital in a state of shock. After another episode of general swelling, the patient was invited to examine her domestic environment. She brought us some parasites, collected at home, particularly on the bed. A morphological examination by entomologists proved these parasites to belong to Argas reflexus (Arg.r.), one of the 31 species of soft ticks. The presence of specific IgE to a protein secreted by the Arg.r. salivary glands was in favour of immediate-type systemic reaction, as supposed by the clinical history.

Anaphylactic reaction to cinoxacin: report of one case associated with inferior acute myocardial infarction.

Cinoxacin is an oral synthetic antibacterial agent, of the second generation quinolones group, with excellent efficacy in respiratory, intra-abdominal, pelvic, and skin and soft tissue infections. Overall, quinolones are well tolerated drugs, although phototoxicity and photoallergenicity is well demonstrated experimentally. In this report we show you a case of a man who presented a anaphylactic reaction associated with myocardial infarction, after taking a capsule of cinoxacin. We suppose that there is a direct participation of the heart in anaphylactic reactions, because acttivated mast-cells mediators can determine cardiovascular effects. Then performed double-blind placebo controlled challenge test with an alternative drug. We did not observe any adverse immediate or late adverse reaction to this drug.

The safety of cluster immunotherapy with aluminium hydroxide-adsorbed honey bee venom extract.

Venom immunotherapy (VIT) with aqueous extracts is considered a life-saving treatment in insect allergy, but systemic side effects are quite common, especially in patients sensitized to Apis mellifera venom. Only a few studies are available regarding depot VIT administered according to the standard weekly schedule, while no data are available for cluster VIT with depot preparations. This study was designed to compare the tolerance of aqueous cluster or rush VIT versus cluster depot VIT in patients sensitized to Apis mellifera. Fifty-five patients with a history of systemic reaction (grade II to IV according to Müller) after an Apis mellifera sting were divided at random into 3 groups. Forty patients were treated with aqueous VIT (20 according to a cluster schedule and 20 according to a rush schedule) and 15 with Depot VIT according to a cluster schedule. All local and systemic side effects were recorded. Four patients belonging to the aqueous-cluster, 4 belonging to the aqueous-rush, and 1 belonging to the depot-cluster schedule had large local reactions after VIT (p < 0.009). Systemic side effects were recorded in 1, 7 and 0 patients (p < 0.003) respectively. No statistically significant difference was found between the two cluster regimens in the frequency of side effects. Depot VIT administered according to a cluster schedule was well tolerated, and its tolerance is better than aqueous-rush VIT for Apis mellifera.
