Satisfaction and quality of life of allergic patients following sublingual five-grass pollen tablet immunotherapy in Spain.

Background: Five-grass pollen tablet is an effective and well-tolerated therapy for patients with allergic rhinoconjunctivitis (ARC). This trial sought to determine the satisfaction and health-related quality of life (HRQoL) of patients undergoing this treatment.

Methods: This was a cross-sectional, multicentre, observational, naturalistic study, following a discontinuous pre- and co-seasonal five-grass pollen regimen over two seasons in Spain (2012, 2013).

A Case of Immediate Hypersensitivity Reaction to Maltitol.

Background: Maltitol is a sugar alcohol that is frequently used as a noncaloric sweetener, although it is also used as an excipient, a plasticizer in gelatin capsules, and an emollient. It has not been previously described as an agent involved in immediate hypersensitivity reactions.

Methods: We report on an anaphylactoid reaction with pharyngeal occlusion suffered by a 60-year-old man after ingestion of a candy containing maltitol syrup.

Short-, Intermediate-, and Long-Term Changes in Basophil Reactivity Induced by Venom Immunotherapy.

Purpose: The basophil activation test (BAT) has been used to monitor venom immunotherapy (VIT) due to its high specificity. A previous study has reported a good correlation between a significant decrease in basophil activation during 5 years of VIT and clinical protection assessed by sting challenge. The following prospective study was performed to examine changes in basophil reactivity over a complete VIT period of 5 years.

Protophormia terraenovae. A new allergenic species in amateur fishermen of Caceres, Spain.

Background: Asticot maggot (Blowfly, Calliphoridae family) is the most important live bait used for angling in our country. Prevalence of allergy to live fish bait in occupationally exposed workers has been described. The purpose of this study was to determine the prevalence of asticot allergy in amateur fishermen and the identification of marketed asticot species in Cáceres, Spain.

Basophil activation test for the in vitro diagnosis of nonsteroidal anti-inflammatory drug hypersensitivity.

There is need for an in vitro diagnostic test for hypersensitivity to nonsteroidal anti-inflammatory drugs (NSAIDs). The purpose of this study was to assess the reliability of one such diagnostic, the basophil activation test. Forty-three drug hypersensitive patients referring several immediate reactions (anaphylaxis, urticaria, angioedema, asthma, and rhinoconjunctivitis) to one or more NSAIDs and 29 controls participated.

Anaphylaxis caused by cloxacillin: diagnosis with seriated analysis by way of basophil activation test.

We report a case of anaphylaxis caused by cloxacillin in a 13-year-old patient. The basophil activation test, performed 25 days after the anaphylactic reaction, was positive to cloxacillin, amoxicillin, and penicillin G and negative to ibuprofen, tolerated by the patient. The analysis was performed 17 days after the reaction was not conclusive because 74% of the basophil population was activated in basal conditions.
