Cold urticaria and celiac disease.

Cold urticaria can be associated with blood and thyroid disorders, drugs, or infections. Celiac disease is an autoimmune enteropathy caused by permanent gluten intolerance. It is often associated with other autoimmune diseases, such as chronic idiopathic urticaria. Nevertheless, association with cold urticaria has not yet been described. A boy aged 3 years 8 months presented local urticaria-angioedema when exposed to cold temperatures. An ice cube test was positive and iron deficiency anemia was demonstrated. He later developed legume intolerance, rhinoconjunctivitis related to pollen sensitization, and asthma. Due to persistence of cold urticaria symptoms and refractory anemia, a test for immunoglobulin A autoantibodies to tissue transglutaminase and an intestinal biopsy were performed. Results of both tests were compatible with celiac disease.A study of human leukocyte antigen indicated a high risk phenotype (HLA, DR6/DR7; DQA 0501, 0201; DQB 0301, 0201). After 7 months of a gluten-free diet, the boy's anemia resolved and he is free of symptoms when exposed to cold. This is a first description of the possibility of an association between celiac disease and cold urticaria. A poor course of cold urticaria in the absence of evidence of another underlying condition should lead to suspicion of celiac disease.

Atopy and bronchial hyperresponsiveness in pure extrinsic childhood asthma.

Nonspecific bronchial hyperresponsiveness and atopy are considered risk factors in the development of asthma. Bronchial responsiveness to allergens could be the most important factor in extrinsic asthma. The trial was designed to investigate the role of specific and nonspecific bronchial responsiveness and atopy in a pure model of extrinsic asthma in children. One hundred and thirty-seven patients with pollen allergy were evaluated. Twenty children with allergy to grass pollen (Lolium perenne) alone, with symptoms only in the grass pollen season, were selected. Their score of symptoms, airway responsiveness to methacholine in and out of season, airway responsiveness to Lolium perenne out of season, and total and specific IgE were assessed. Twelve were male and eight female. Mild asthma was observed in 14, and moderate asthma in six. Age of onset of symptoms ranged from three to 13 years of age. Significant seasonal increase in airway responsiveness to methacholine was found (p = 0.002). Specific bronchial challenge test was positive in all patients. Lolium pernne PD20 ranged from 2.3 to 155.5 inhalation units. An inverse association between age of onset of symptoms and severity of asthma was shown (p = 0.001). Increase in nonspecific bronchial responsiveness was related to the appearance of symptoms during the spring, but it showed no relationship to the severity of symptoms. Severity of asthma during the spring correlated with the intensity of allergen airway responsiveness (p = 0.02). Levels of total and specific IgE were not related to the degree of specific or nonspecific airway responsiveness. Severity of extrinsic childhood asthma is determined by bronchial response to allergens. Bronchial hyperresponsiveness to methacholine during the spring can be the consequence of environmental exposure to allergens. The intensity of airway responsiveness to methacholine has no predictive value in the severity of pure extrinsic childhood asthma.

Evaluation of drug-related hypersensitivity reactions in children.

Patients with drug reactions are often referred to allergists for "allergy". Skin testing and clinical history seem to have a good negative predictive value, however, although drug challenge could be dangerous, it is the only way to confirm the diagnosis. We aimed to demonstrate that most children with a history of non-life-threatening drug reactions do not have a true drug allergy and examined the use of drug challenge in childhood. Patients with reactions were referred to our clinic by pediatricians. In 1 year, 354 reactions were studied in 239 children. Patients were classified according to their positive or negative history of drug allergy. Skin prick testing was done in all cases. Exclusion criteria for challenge included drug anaphylaxis, Stevens-Johnson syndrome, systemic reactions with severe concomitant illness, beta-inhibitor drug therapy or positive skin test to the implicated drug with a positive history. It was found that the beta-lactam antibiotics were involved in 50% of suspected reactions, aspirin in 10% and sulfonamides in 9%. Histories were considered positive only in 25%. Drug challenges confirmed only 4% of all reactions. It was concluded that drug challenge may be the gold standard for most childhood reactions that are considered to be allergic, non-life-threatening and drug-related. Only 4% of these suspected reactions were exclusively caused by drug allergy.

Asthma in children and ASA intolerance.

Intolerance to acetylsalicylic acid (ASA) in asthmatics has been widely studied in the adult population, and to a lesser extent in children. In the present study, we present 16 asthmatics between the ages of 2 and 14 suffering from asthma induced by ASA ingestion, and the clinical characteristics are compared with a population of asthmatic children with a negative challenge test. The following results were obtained: 1) in contrast to in adults, females are not predisposed to ASA intolerance in childhood, the male:female ratio being the usual 2:1 in infantile asthma; 2) ASA intolerance can appear at a very early age (in our series the youngest was 1 year old); 3) extrinsic asthmatics are the most commonly affected, and also children with exercise-induced asthma; 4) in extrinsic asthmatics with asthma attacks precipitated by ASA, sinusitis is more frequent than in extrinsic asthmatics with ASA tolerance; 5) polyposis is exceptional; 6) the presence of associated urticaria is frequent, and much greater than in adult ASA-intolerant asthmatics; and 7) the results of the challenge with NSAIDs are similar to those obtained in adult patients, which would indicate a common pathophysiological mechanism related to the capacity of these drugs to inhibit cyclooxygenase activity.

[Incidence of allergy to cow's milk protein in the first year of life and its effect on consumption of hydrolyzed formulae]. / Incidencia de alergia a proteínas de leche de vaca en el primer año de vida y su repercusión en el consumo de hidrolizados.

OBJECTIVES: The aims of this study were to determine the incidence of allergy to cow's milk protein in infants and the cost of treatment with hydrolyzed formulae in the Autonomous Community of Madrid. PATIENTS AND METHODS: Infants with suspected adverse reaction to cow's milk protein born between March 1, 2000 and February 28, 2001 within the catchment area covered by the pediatric services of Hospital La Paz were studied. The diagnostic algorithm of allergy to cow's milk protein of our department was used. The theoretical consumption of hydrolyzed formulae in the treatment of allergic infants was calculated and extrapolated to the Community of Madrid. RESULTS: There were 5367 live births in the above-mentioned catchment area. Adverse reaction to cow's milk protein was suspected in 185 infants. Allergy to cow's milk protein was confirmed in 101 (54 %). The incidence of allergy to cow's milk protein was 101/5356 (1.9 %). In the same period there were 57 078 live births in the Autonomous Community of Madrid. The number of infants that might be allergic in one year would be 1084. The cost of hydrolyzed formulae per infant and year would be 1,585.72 Euros. Thus, the cost of hydrolyzed formulae in the 1084 allergic infants would be 1,718,922.9 Euros; in the 923 in whom allergy was ruled out, the cost would be 1,463,621.8 Euros. CONCLUSIONS: The incidence of allergy to cow's milk protein in the first year of life is at least 1.9 %. The correct diagnosis allows us to rule out allergy to cow's milk protein in almost half of the cases, thus avoiding the use of unnecessary substitutive diets involving a high cost.

Enfermedades periodontales durante el embarazo y suasociación con parto prematuro y bajo peso alnacimiento. Evidencias y controversias / Periodontal diseases in pregnancy and its association with preterm delivery and low birth weight. Evidence and controversies

Aunque el embarazo implica cambios fisiológicos que en general no suponen un riesgo por sí mismos para la salud tanto de la madre como del niño, durante este periodo las infecciones de diversa índole pueden poner en riesgo el curso normal del mismo e incluso comprometer la salud del neonato, siendo los partos prematuros y el bajo peso al nacimiento las patologías que con más frecuencia se asocian con las infecciones. Entre estas infecciones comienza a tener cierta relevancia, desde hace ya algunos años la enfermedad periodontal. Esta revisión bibliográfica recoge las conclusiones de distintas publicaciones sobre la relación entre enfermedad periodontal, los partos prematuros y el bajo peso al nacimiento, encontrándose resultados variables (AU)

Pregnancy involves physiological changes which, although not meaning a risk in itself for either the mother’s or the baby’s health, may lead to the development of new pathologies, including periodontal disease. This bibliographical revision compiles the conclusions drawn by different publications about the relationship between periodontal disease and low-weight preterm births, highlighting variable results (AU)

Tomato allergy in children and young adults: cross-reactivity with latex and potato.

BACKGROUND: Several studies have shown that allergy to natural rubber latex is associated with cross-reactivity to certain foods such as tomato and potato. The objective was to investigate the clinical and immunologic differences between a group of patients with clinical allergy to tomato and latex and another which had only clinical allergy to tomato. We also aimed to assess, in vitro, the relationship of tomato and latex allergens, which could explain the cross-reactivity. METHODS: Forty patients with histories of adverse reactions to tomato and IgE-mediated hypersensitivity were enrolled in the study. Tomato, latex, and potato components were analyzed by SDS-PAGE immunoblotting. CAP and immunoblot inhibition were used to study allergen cross-reactivity. RESULTS: Patients from group A had a mean age of 13.2 years, and in group B the mean age was 21.7 years. In group B, 9/10 patients belonged to the latex-fruits syndrome. All patients of both groups tolerated potato. Immunoblotting patterns obtained with patients' sera from pool A showed IgE-binding bands to tomato ranging from 44 to 46 kDa and a triple band at 67 kDa. For latex, there was a strong binding at 44 kDa, and potato showed a strong band of 44 kDa and a 67-kDa triple band. In pool B, the binding to the band of 44 kDa in latex and tomato was more intense than in pool A. In pool A, immunoblot inhibition with potato allergen showed an intense inhibition of the three allergens (potato, latex, and tomato); with latex, inhibition was partial and with tomato, a complete inhibition of tomato and latex was observed, and a partial inhibition of potato. In pool B, the inhibition pattern followed a similar tendency to pool A. The CAP inhibition confirmed the high rate of cross-reactivity between tomato, potato, and latex. CONCLUSIONS: In our study, tomato, potato, and latex showed a common band of 44-46 kDa probably corresponding to patatin. This protein could be implicated in the high cross-reactivity between tomato, latex, and potato observed in the immunoblot and CAP inhibition.

Allergy to lentils in Mediterranean pediatric patients.

BACKGROUND: Peanuts and soybeans are the major legumes involved in human food allergy; however, scarce data exist on adverse reactions to other temperate legumes, such as lentils. OBJECTIVE: The purpose of this study was to identify patients who are allergic to lentils, to assess clinical features and other associated food allergies, and to characterize allergens in lentil extract. METHODS: Twenty-two children each with a history of adverse reactions to lentils were enrolled in the study. The diagnosis of lentil allergy was based on food challenges or a convincing history of anaphylaxis, with positive skin tests and/or specific serum IgE to lentils. Lentil components were characterized by SDS-PAGE immunoblotting. RESULTS: Twenty of 22 subjects had symptomatic allergy to lentils at the diagnostic time. The most frequent symptoms were oropharyngeal symptoms (40%) and acute urticaria (30%); 3 patients also reported symptoms when they were exposed to steam from cooked lentils. In 18 patients, symptoms after lentil ingestion started under 4 years of age (median, 2.7 years). Nine patients had allergic reactions to other legumes: chick peas (6 patients), peas (2 patients), and green beans (1 patient). Immunoblotting patterns obtained with patients' sera showed IgE-binding bands ranging from 14 to 84 kd. Five sera recognized 9 or more IgE-binding bands, and more than 50% of patients who were tested have specific IgE antibodies to 7 components in lentil extract. CONCLUSION: Allergic reactions to lentils started early in life, usually below 4 years of age; oropharyngeal symptoms and acute urticaria were the most common symptoms through ingestion, and symptomatic reactivity to chick peas is frequently associated.
