Abstract
BACKGROUND AND OBJECTIVE Cow milk and egg are the most frequent causes of food allergy in the first years of life. Oral immunotherapy (OIT) has been investigated as an alternative to avoidance diets. No clinical practice guidelines on the management of OIT with milk and egg are currently available. Objectives: To develop clinical guidelines for OIT based on available scientific evidence and the opinions of experts. METHODS A review was made of studies published between 1984 and June 2016, doctoral theses published in Spain, summaries of communications at scientific meetings (SEAIC, SEICAP, EAACI, and AAAAI), and the consensus of opinion established by a group of experts from the scientific societies SEICAP and SEAIC. RESULTS Recommendations were established regarding the indications, requirements and practical aspects of the different phases of OIT, as well as special protocols for patients at high risk of adverse reactions. CONCLUSIONS Clinical practice guidelines based on the consensus reached between Spanish experts are presented for the management of OIT with milk and egg.

Abstract
In Spain, peanut allergy is increasingly prevalent. Successful protocols for the induction of oral tolerance (LOT) with several foods have been reported. We aimed to induce clinical tolerance to peanut in a child with severe peanut allergy (age 4 years, facial urticaria and lip angioedema upon licking a peanut; peanut skin prick test, 13 x 10 mm; specific immunoglobulin (Ig) E > 100 kUA/L). At age 6, the threshold oral challenge dose was 62.5 mg. Several peanut solutions were prepared and sequentially administered at the patient's home. Over 138 days, the dose was increased from 0.625 to 5500 mg. There were 43 mild-to-moderate reactions (28% of the doses administered). Pre-LOT and post-LOT peanut IgE and IgG4 values were 265 vs 487 kUA/L, and 6.11 vs 14.8 mg/L. This is the first report of successful LOT to peanut in Spain. This home-based regimen is safe under permanent and close medical supervision by an allergist.

Abstract
BACKGROUND Plane trees, as Platanus acerifolia, are an important source of airborne allergens in cities of the United States and Western Europe. Little is known about the relevant allergens of this pollen. The aim of this study was to identify relevant allergens from P. acerifolia pollen and purify and characterize a major allergen of 18 kDa. METHODS P. acerifolia pollen extract was fractionated using ion exchange, gel filtration, and reverse-phase chromatography. Analyzes were carried out by EAST, SDS-PAGE, isoelectric focusing, immunoblotting and amino-acid sequencing. RESULTS An 18-kDa protein from the P. acerifolia pollen extract, which we named Pla a 1, was purified. This nonglycosylated protein had an isoelectric point value higher than 9.3 and was recognized by up to 92% of monosensitized Platanus allergic patients and 83% of polyzensitized patients. Sequencing of its N-terminal yielded an amino acid sequence which showed no homology to the known proteins in the databases. Other relevant allergens detected in monosensitized patients were proteins of 43 and 52 kDa, with immunoglobulin (Ig)E-binding prevalences of 83 and 42%, respectively. Profilin was an important allergen in polyzensitized patients. CONCLUSIONS The most relevant allergens from the P. acerifolia pollen have been determined. A major allergen, specific of this pollen, and named Pla a 1, has been purified and characterized.

Abstract
We evaluated the clinical characteristics found in 29 children who showed allergic symptoms after direct and/or indirect contact with fish, from 197 children diagnosed with IgE-mediated fish hypersensitivity. Allergic reactions to fish through ingestion began in most patients (79%) within the first 24 months of life. All the patients showed cutaneous symptoms, either alone or associated with other clinical manifestations. Whiff and hake were the species more frequently implicated in eliciting clinical manifestations upon ingestion. After diagnosis, all patients were placed on a strict fish avoidance diet. During this period of avoidance, 29 patients reported allergic reactions (mean age 5 years, 6 months; SD 4 years, 2 months) after incidental skin contact with fish. Clinical manifestations after touching fish were only cutaneous in 28 of the 29 studied patients. One showed local urticaria with wheezing. The majority reported two or more episodes. Incidental skin contact with fish could play an important role in accidental encounters with fish particles in children on a fish avoidance diet for fish IgE-mediated hypersensitivity. Such exposures could result in immunologic immediate contact reactions and in some cases could lead to systemic reactions (contact urticaria syndrome).

Abstract
IgE-antibody reactivity to boiled Atlantic shrimp (Pandalus borealis) and German cockroach (Blattella germanica) of sera from 89 patients, sensitive to one or the other, was investigated with an enzymatic immunoassay for specific IgE detection (CAP-FEIA System, Pharmacia, Sweden). IgE serum levels to both antishrimp and anticockroach allergens were found to be positive in 76 of the 89 (85.4%) tested sera. A positive anticockroach IgE was very rare in the absence of detectable antishrimp IgE (five of 89 sera). Linear regression analysis on antishrimp and anti-German cockroach IgE levels-log plot revealed a correlation coefficient (r) of 0.73. Inhibition experiments showed that boiled Atlantic shrimp extract inhibited CAP with German cockroach, and vice versa. Immunoblotting showed the strongest IgE binding for both allergenic extracts between 30 and 43 kDa. By blot inhibition, the binding capacity of German cockroach was totally abolished by Atlantic shrimp extract, while German cockroach extract only partially IgE binding to Atlantic shrimp. Cross-reactivity exists between shrimp, an important food allergen, and German cockroach, which has an increasing role in allergic asthma. It could be important to determine the clinical significance of cross-allergy to both allergens, in which exposures occur in different ways.

Abstract
We evaluated the clinical characteristics found in 21 children who showed allergic reactions upon incidental inhalation of fish odors or fumes, from 197 diagnosed with IgE-mediated fish hypersensitivity. Allergic reactions to fish via ingestion began in most patients (86%) within the first 24 months of life. The vast majority (19/21) of patients showed cutaneous symptoms, either alone or, less frequently, associated with other clinical manifestations. Hake and flounder were the species of fish most frequently implicated in eliciting clinical manifestations upon ingestion. After diagnosis, all these patients were placed on a strict fish-avoidance diet. During this period of avoidance, patients reported allergic reactions (mean age 7 years) after incidental exposure to airborne fish odors or fumes. Clinical manifestations through inhalation were respiratory (mainly wheezing) in 12 patients and cutaneous (mainly urticaria) in nine patients. Nineteen of 21 patients reported three or more episodes upon exposure to fish aerosols; in most cases, these episodes occurred at home when other people were eating fish. In conclusion, incidental inhalation of fish odors or fumes could play an important role in accidental and unknown encounters with fish in children on fish-avoidance diets for fish IgE-mediated hypersensitivity. Such exposures could elicit clinical symptoms and could have some effect in delaying the development of tolerance.
