RESUMO
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.

Severe delayed drug-induced skin reactions in children are not common but potentially serious. This article describes aspects concerning the etiology, pathogenesis and clinical manifestations of these processes; it presents three paediatric cases, namely STS (Steven Johnson Syndrome), TEN (toxic epidermal necrolysis), probably related to amoxicillin/clavulanate and ibuprofen and DRESS (a drug reaction with eosinophilia and systemic symptoms) secondary to phenytoin; and in relation to them, the diagnosis and the treatment of these processes are discussed and reviewed. The AGEP (acute generalised exanthematous pustulosis) is also reviewed. The aetiological diagnosis of severe non-immediate reactions is difficult, and the value of current allergological testing is not well defined in these cases. Diagnosis is based on clinical history, the empirical risk of drugs to trigger SJS/TEN or DRESS, and the in vivo and in vitro testing of the suspect drug. Skin biopsy confirms that the clinical diagnosis and delayed hypersensitivity tests, especially the patch test and the lymphoblastic transformation test (LTT), may be important to confirm the aetiological diagnosis, in our cases emphasising the latter. These diseases can be life threatening (especially DRESS and TEN) and/or have a high rate of major complications or sequelae (SJS/TEN). The three cases described progressed well without sequelae. All were treated with corticosteroids, which is the most currently accepted treatment although the effect has not been clearly demonstrated.

BACKGROUND: Limited published evidence shows oral desensitization to be a potential intervention option for cow's milk protein (CMPs) allergy. OBJECTIVE: The aim of this study was to evaluate the safety and efficacy of oral desensitization in 2-year-old children with cow's milk allergy, as a treatment alternative to elimination diet. METHODS: A total of 60 children aged 24-36 months with IgE-mediated allergy to CMPs were included in this multi-center study and were randomized into two groups. Thirty children (group A: treatment group) began oral desensitization immediately, whereas the remaining 30 (group B: control group) were kept on a milk-free diet and followed-up for 1 year. RESULTS: After 1-year follow-up period, 90% of the children in group A had become completely tolerant vs. 23% of the children in group B. In group A, cow's milk skin reactivity and serum-specific IgE to milk and casein decreased significantly from the initial assessment, whereas group B showed no significant change after 1 year of follow-up. Twenty-four patients (80%) developed some reaction during the treatment period: 14 children developed moderate reaction (47%) and 10 mild reaction (33%). The most common manifestations were urticaria-angioedema, followed by cough. CONCLUSIONS AND CLINICAL RELEVANCE: In this study, oral desensitization was found to be effective in a significant percentage of 2-year-old children with cow's milk allergy. Oral desensitization appears to be efficacious as an alternative to elimination diet in the treatment of 2-year-old children with cow's milk allergy. The side-effect profile appears acceptable but requires further study.

BACKGROUND: The aim of the present study is to assess whether a single determination of the fraction of exhaled nitric oxide (FENO), added to the measurements usually taken during a routine checkup, helps in the prediction of the recurrence of asthma attacks in controlled patients who are not receiving any baseline treatment; and whether or not treatment of the said latent inflammation is appropriate. METHODS: Observational study of prospective cohorts. Over a period of three months, data was collected from 28 patients (6 to 14 years) who met the conditions of the inclusion criteria, with a follow up appointment after six months. RESULTS: Patients were divided into two groups: 13 with FENO values of 49 and over, and 15 with values of under 49. Five patients in the subgroup with low FENO values suffered recurrence, in contrast to only one in the group with high values. The positive predictive value of the high values of the FENO was 7.69, with no significant differences between the two groups. CONCLUSIONS: Certain doubts were raised about the usefulness of the FENO, as opposed to the traditional methods of asthma control with regard to the therapeutic management of clinically controlled patients who are not receiving treatment and who have high FENO values. It would appear unwise to recommend the systematic treatment of patients with high FENO values, when measured during a routine check-up, in cases of asthma with an allergic component and are asymptomatic or in a phase of asthma under good control.

The results of the cutaneous tests with fungus, and the repercussion of the fungal allergens in asthma via inhalatory route has been a controversial subject for many years. The lack of characterization, purification and standardization of the allergens make the results of the cutaneous tests highly variable. The diagnostic value of the bronchial provocation test (BPT) in asthma, associated with suspicious fungal hypersensitivity, correctly performed with adequate controls and concentrations of non-irritant fungal allergens has been emphasized by various authors. The motive of the present study to demonstrate, by means of the BPT with Alternaria, if the lung is the target organ of hypersensitivity demonstrated by cutaneous tests and RAST, comparing the obtained results by the Score of FOUCARD (fig. 1), with the result of the inhalatory test. The specificity and reproductibility of the BPT was likewise verified according to the employed allergen and its non-unspecific irritant concentrations to the airway. Twenty patients of both sexes, with ages ranging between 7 and 14 years, distributed in two groups, were studied and diagnosed as having bronchial asthma. Group I: Fourteen patients diagnosed with asthma, for hypersensitivity to Alternaria with Score of FOUCARD equal or greater than 5 (Table I). Group II: Control group composed of 6 patients with negative allergological findinds to Alternaria with bronchial hyperreactivity demonstrated in for cases by BPT positive against Dermatophagoides and in two cases with positive methacholine test (PC20 less than 8 mg./ml.). The inhalation of the allergen was performed following the described method by Cockcroft.(ABSTRACT TRUNCATED AT 250 WORDS)
