OBJECTIVE: To study the relationship between the primary sensitization to wasp venoms and the geographical and seasonal circumstances of the anaphylaxis-induced sting. METHODS: We performed a retrospective review of 115 patients (age 10-80) who suffered a systemic reaction to a wasp sting. Season and type of locality (urban or rural) at the moment of the sting were recorded. Serum specific IgE levels to venoms from Vespula and Polistes were measured, and a primary sensitization was determined to whichever genus of wasp for which the highest class of specific IgE was observed. The primary sensitization in relation to the type of locality and the season was assessed using the chi-square test. RESULTS: Most reactions occurred in urban areas (67.8 %), and in the summer season (63.4 %). Most patients were sensitized to Vespula venom (94.8 %). Primary sensitization was to Vespula in 56.5 %, to Polistes in 10.4 %, and undetermined in 33 %. The distribution of geographical areas did not show significant differences in relation to primary sensitization (p > 0.05). Most patients with primary sensitization to Vespula suffered the anaphylaxis-induced sting after the spring season, with a statistically significant result (p < 0.05). CONCLUSION: In our population, the probability of Vespula sting is higher than Polistes sting when the reaction occurs after spring. This finding can help us to identify the responsible vespid when the diagnostic tests do not provide an accurate result.

BACKGROUND: The aim of this study was to analyze the frequency of clinical features and the severity of systemic reactions to wasp stings, and to establish their relationship with mean age, sex, and atopy. METHODS: We studied 115 patients who suffered an anaphylactic reaction to wasp sting and showed specific IgE to venoms from Vespula and/or Polistes. In all patients, age, sex and personal history of atopy were registered. Cutaneous, respiratory, cardiovascular and gastrointestinal involvement during the course of the reaction was investigated. Each patient was assigned a severity grade according to a simple two-grade classification based on Müller's criteria. Bivariable analysis was performed to analyze the associations among mean age, sex and atopy and the symptoms and severity of the reaction. RESULTS: The mean age was 40.2 years. There were 60 males (52.2 %) and 55 females (47.8 %). Twenty-six patients (22.6 %) were atopic. The percentages of involved systems were as follows: skin 90.4 %, respiratory 54.8 %, cardiovascular 33.9 %, and gastrointestinal 21.7 %. Reactions were mild in 40.8 %, and severe in 59.1 %. The mean age was higher in patients without cutaneous symptoms (p < 0.05). Cardiovascular involvement was more frequent in males (p < 0.05). No other significant differences were found. CONCLUSION: The symptoms of systemic reactions to wasp venom most frequently involved the skin, while reactions without cutaneous involvement were more frequent in older patients. Cardiovascular involvement was more common in males. The clinical pattern was not determined by atopy and the variables studied were not related to severity.

BACKGROUND: The use of opioids as analgesics is becoming increasingly widespread, which may have repercussions in patients with urticaria or asthma, as these agents frequently cause adverse reactions. MATERIAL AND METHODS: We present three patients who developed allergic reactions after receiving codeine: two patients who developed acute urticaria, and a third asthmatic patient receiving specific immunotherapy who developed bronchospasm. Skin prick-testing (SPT) and intradermal reaction (IDR) tests with various opioids were performed, followed by controlled oral challenge. Prick tests and IDR were also carried out in 20 controls. RESULTS: Similar SPT and IDR results were recorded in the three patients and in the controls. In the case of controlled oral challenge with codeine, patient 1 suffered bronchospasm, while patient 2 developed generalized urticaria. The test was not performed in the third patient. All of the patients tolerated tramadol 50 mg without problems. We advised the use of tramadol as analgesic and fentanyl or remifentanil as anesthetics. DISCUSSION: In these types of manifestation, the pharmacological properties of the opioids used are highly important, particularly as regards their histamine-releasing potential. Codeine, morphine and pethidine present the greatest histamine-releasing capacity, while tramadol, fentanyl and remifentanil do not release histamine and their use is thus recommended in pulmonary disease requiring opioid administration. Cutaneous symptoms are more frequently caused by opioids than by respiratory symptoms, since these drugs act on the MTC mast cell population, which is more prevalent in the skin than in the lungs. Some of this action is inhibited by naloxone. CONCLUSIONS: In most patients, these reactions are not IgE-mediated. Consequently, SPT and IDR are of little diagnostic value, and controlled oral challenging with the suspect drug or with one of the non-histamine releasing agents should be used. The patch test is useful in occupational contact dermatitis.

Introducción: Como fármacos analgésicos, cada vez está más extendido el uso de opiáceos y éstos pueden tener repercusiones sobre pacientes con urticaria o asma. La mayoría de las veces la causa es un efecto secundario. Material y Métodos: Presentamos dos pacientes que han tenido una urticaria tras la toma de codeína y otra paciente asmática que está recibiendo inmunoterapia y tiene crisis de broncoespasmo tras la toma de éste fármaco. Se realizan prick-test e IDR con varios opiáceos, y tras esto se realiza exposición oral controlada. También se realizan pricks e IDR a 20 controles. Resultados: En los tres casos y en los controles se obtienen resultados similares de los pricks y de las IDR. En la exposición oral controlada con codeína, la paciente 1 sufre un broncoespasmo, la 2 una urticaria generalizada y la 3 no se realiza. Las tres toleran tramadol 50mg sin problemas. Se recomienda el uso de tramadol como analgésico y fentanilo o remifentanilo como anestésicos. Discusión: En este tipo de cuadros las propiedades farmacológicas de los opiáceos son muy importantes, puesto que van a venir marcados por la potencia de liberación de histamina. La codeína, la morfina y la petidina, son los mayores liberadores y por el contrario, el tramadol, el fentanilo y el remifentanilo no lo son y están recomendados en patología pulmonar que necesiten opiáceos. Los opiáceos suelen producir en mayor número de ocasiones cuadros cutáneos por que actúan sobre todo sobre los MTC que son más numerosos en la piel que en el pulmón. La Naloxona inhibe en parte ésta acción. Conclusiones: La mayoría de reacciones de este tipo no son IgE mediadas, por lo que los pricks e IDR no tienen ningún valor, y se debe de recurrir a la exposición controlada con el fármaco implicado o con uno de los no liberadores de histamina. Las pruebas del parche si que tienen utilidad en las dermatitis de contacto ocupacionales

UNLABELLED: Allergen immunotherapy dates back to 1911 and has been used successfully to treat large numbers of patients throughout the last century. CASE REPORT: a 66-year-old woman presented with symptoms of allergic rhinitis and asthma due to sensitization to Cupressus arizonica. Specific immunotherapy was prescribed as a continuous 2-year treatment with a depot preparation of standarized and characterized allergen extracts of Cupressus arizonica pollen. Forty-eight hours after one maintenance dose of 0.8 cc, the patient presented palpable violaceous purpuric lesions and pruritus on both legs. We performed skin prick and intradermal tests with Cupressus arizonica. Twenty-four hours later, the 1/1 dilution intradermal skin test was positive. Biopsy showed leukocytoclastic vasculitis. CONCLUSIONS: A middle-aged woman experienced cutaneous non-necrotizing vasculitis after 2 years of maintenance immunotherapy. The interval between injections and the first appearance of cutaneous lesions suggests a type III hypersensitivity immune reaction. Skin biopsy of the positive intradermal test also supports this hypothesis.

BACKGROUND: The management of glucocorticoid dependent and resistant asthma encompasses a group of problems, affecting as much control of clinical symptoms as the onset of adverse effects to prolonged use of steroids. MATERIALS AND METHODS: Woman 52 years old, steroid dependent asthma fifteen years ago. She has important adverse effects in consequence of the use of systemic glucocorticoids. The employment of methotrexate attained decrease in the dosage of steroids temporarily. The worsening of the clinical situation and deterioration of secondary effects by use of steroids necessitated treatment with nebulized lidocaine. A 2% solution to initial dosage was administered three times daily. The maximal dosage needed was 80 mg three times daily. RESULTS: After three months of lidocaine treatment, the patient was able to reduce oral steroids eventually discontinuing these drugs, and the effects secondary to exogenous hypercortisolism disappeared. Moreover, an improvement in clinical symptoms and quality of life was observed with stability in the pulmonary function. CONCLUSIONS: The use of nebulized lidocaine could be useful and provide alternatives in patients with severe asthma.

Antecedentes: El cuidado de los pacientes con asma bronquial corticodependiente y corticorresistente supone un conjunto de problemas, que afectan tanto a la situación clínica como al desarrollo de efectos adversos secundarios a una prolongada terapia esteroidea. Material y métodos: Mujer de 52 años con asma corticodependiente de 15 años de evolución con manifestaciones clínicas de hipercortisolismo. El uso de metotrexato oral consiguió un descenso transitorio en las dosis de esteroides. El agravamiento de la situación clínica obligó a un aumento de las dosis de esteroides con el consiguiente empeoramiento de los efectos secundarios. Por este motivo se instauro tratamiento con lidocaína nebulizada al 2 % a dosis iniciales de 40 mg cada 8 horas hasta una dosis máxima de 80 mg cada 8 horas. Resultados: Tras 3 meses de tratamiento con lidocaína nebulizada se reducen las dosis de corticoides orales hasta la suspensión total de estos con la desaparición o mejoría de los efectos secundarios al hipercortisolismo. Se produjo una mejoría en su situación clínica así como un aumento en la calidad de vida de la paciente con estabilidad en los parámetros de función pulmonar. Conclusiones: El uso de lidocaína nebulizada podría representar una alternativa eficaz y segura en el tratamiento del asma de difícil manejo

BACKGROUND: The incidence of asthma is high, especially in young people, a population group that includes women of reproductive age. We reviewed recent publications on asthma control during pregnancy to avoid undesired effects on both the mother and fetus. The prevalence of rhinoconjunctivitis is also high, although this disease is often under-treated by physicians. The use of beta2-agonists, corticoids (systemic/inhaled/nebulized), epinephrine and specific allergen immunotherapy is discussed. METHODS: We reviewed recent publications on asthma during pregnancy as well as other articles of interest. Articles providing data on drug therapy, overall strategies and patient education were selected. Sufficient drugs are available for the management of this disease and under-treatment cannot be justified. CONCLUSIONS: Pregnancy is not a disease, but constitutes a period when special care must be taken with underlying diseases. The aim of asthma treatment during pregnancy is to prevent fetal complications due to the effects of medication and asthma crises by keeping the mother symptom free and preventing possible exacerbations. Almost all authors agree that asthma crises in pregnant women should be treated no differently from those in non-pregnant women. Treatment of rhinoconjunctivitis should not be stopped during pregnancy since a wide variety of FDA category B drugs is available. Specific allergen immunotherapy should not be suspended during pregnancy as it is not contraindicated. However, this therapy should not be initiated during pregnancy.

Introducción: El asma es una enfermedad con alta incidencia sobre todo en gente joven, grupo de población al que pertenecen las mujeres en edad fértil. Hemos revisado los últimos artículos sobre el tema para poder mantener el asma bien controlada y así evitar efectos no deseados tanto en la madre como en el feto. Igualmente se aborda el control de la rino-conjuntivitis, tan incapacitante para multitud de personas y tan olvidada e infratratada por muchos profesionales. Intentamos dar una perspectiva que nos parece razonable para el uso de medicación como β -adrenérgicos, corticoides (sistémicos/inhalados/nebulizados), epinefrina e inmunoterapia específica con alergenos inhalantes. Material y métodos: Hemos revisado los últimos artículos sobre el tema y los que nos han parecido más relevantes. Además no sólo nos hemos centrado en el aspecto farmacológico, sino que hemos tratado de buscar aquellos textos donde se da también una estrategia de tratamiento global, sin descuidar la educación en el manejo de su enfermedad. En esta revisión se comprueba que existe medicación suficiente para el control de estas enfermedades por lo que no hay motivo para infratratar. Conclusiones: El embarazo no es una enfermedad, sino un momento en la vida de una mujer en el que hay que tener mayor control del habitual sobre su patología de base. El objetivo del tratamiento del asma en el embarazo es que la paciente esté libre de síntomas y prevenir las posibles exacerbaciones, para así evitar un mayor daño fetal, tanto por la medicación que se necesita, como por los efectos de la crisis sobre el feto. Es importante destacar que casi todos los autores coinciden en que una crisis asmática en una mujer embarazada se trata igual que en una paciente no embarazada. No hay que dejar de tratar la rino-conjuntivitis por parecer una patología menor ya que se dispone de un importante arsenal terapéutico catalogado como de categoría B por la FDA. La inmunoterapia específica con alergenos no está contraindicada en el embarazo, ni hay que suspenderla, pero no está recomendado iniciarlo durante el mismo

BACKGROUND: Despite its clinical effectiveness, allergen immunotherapy (AIT) remains controversial because serious systemic reactions can occur during its administration. Most of the studies on the safety of AIT are retrospective and use different methods, which frequently depart from daily clinical practice. OBJECTIVE: The aim of this study was to determine risk factors for adverse reactions, especially systemic adverse reactions, produced during routine AIT administration. METHODS: We registered 5,768 consecutive doses of standardized extracts administered to 273 patients in conventional schedules, following the recommendations on safety and data collection of the European Academy of Allergology and Clinical Immunology. Of the 273 patients, 236 were asthmatics, 28 had rhinitis and 9 received immunotherapy due to Hymenoptera anaphylaxis. RESULTS: We examined 143 local reactions (2.48 % of the doses) and 145 systemic reactions (78 immediate and 67 delayed). Risk factors for developing an immediate systemic reaction were asthma severity, sensitization to molds, the most concentrated vials and a fall in peak expiratory flow of more than 15 % or an immediate systemic reaction in the previous dose. Late systemic reactions were significantly more frequent with less concentrated vials and in patients with late local reactions in the previous dose. No serious reactions were registered. CONCLUSIONS: We believe that AIT is reliable when used with strict safety protocols and administered by specialized staff. Risk factors for adverse reactions to this type of treatment can be identified and reduced by systematic data collection.

Antecedentes: La inmunoterapia con alergenos es aún controvertida para algunos grupos, a pesar de su eficacia clínica, porque puede provocar reacciones sistémicas graves durante su administración. La mayoría de estudios sobre la seguridad de la inmunoterapia con alergenos son retrospectivos y emplean diferentes metodologías, muchas veces apartados de la realidad clínica diaria. Objetivos: El ánimo de este estudio fue conocer los factores de riesgo de las reacciones adversas, especialmente sistémicas, producidas durante la administración rutinaria de inmunoterapia. Métodos: Registramos 5.768 dosis consecutivas de extractos estandarizados administrados a 273 pa- cientes con pautas convencionales, siguiendo las recomendaciones de seguridad y recogida de datos de la EAACI (European Academy of Allergology and Clinical Immunology). De todos los pacientes 236 eran asmáticos, 28 riníticos y 9 recibieron inmunoterapia por anafilaxia por Himenópteros. Resultados: Registramos 143 reacciones locales (2,48 por ciento de las dosis), y 145 reacciones sistémicas (78 inmediatas y 67 tardías). Encontramos como factores de riesgo para el desarrollo de reacciones inmediatas sistémicas: la gravedad del asma, la sensibilización a hongos, los viales mas concentrados, la caída del PEF superior al 15 por ciento en la dosis previa y la presencia de otra reacción sistémica inmediata en la dosis anterior. Las reacciones sistémicas tardías fueron significativamente mas frecuentes con los viales menos concentrados y en los pacientes con reacciones locales tardías en la dosis previa. No se produjo ninguna reacción grave. Conclusiones: Creemos que la IT es segura cuando se emplean protocolos de seguridad estrictos y es administrada por personal especializado. La recogida sistemática de datos permite conocer y reducir los factores de riesgo relacionados con las reacciones adversas a este tipo de tratamiento (AU)

INTRODUCTION: Auriculotemporal nerve syndrome is characterized by erythema, perspiration, heat and pain localized in the area supplied by the auriculotemporal nerve in response to gustatory stimuli after the ingestion of different types of food. This syndrome may be confused with food allergy. CASE REPORT: A 21-year-old woman complained of erythema, sweat and heat in the right cheek after intake of several foods such as chocolate, fruits, and nuts for the previous 8 months. She had fractured her jaw two years previously. METHODS: Skin prick tests were performed with a standard battery of common inhalant allergens and with an extensive panel of food allergens. Prick-by-prick tests were also performed with fruits, nuts, and cacao. Total and specific IgE were measured. Open oral food challenge test was performed. RESULTS: Skin prick tests were positive for grass and olive pollen. Prick-by-prick tests and specific IgE antibodies to the different foods were all negative. Open oral challenge test with apple reproduced the symptoms. CONCLUSIONS: This benign syndrome is often misdiagnosed as a food allergy.
