RESUMO

Introduction. Allergic rhinitis (AR) is one of the most frequent chronic diseases in the pediatric population; it affects the quality of life of children and their families, has economic impact, and is frequently underdiagnosed and undertreated. Given the scarcity of local data, here we describe the prevalence of AR and the clinical characteristics of the study population. Population and methods. Observational, cross-sectional study in patients younger than 19 years. Results. A total of 250 patients were randomly included; their mean age was 9 years (SD: 5). AR was diagnosed in 14 of them. The prevalence of AR was 6%. Conclusions. The prevalence of AR in our setting was 6%. AR should be given the relevance it deserves so as to provide an adequate diagnosis and treatment.

RESUMO

La rinitis alérgica (RA) es una de las enfermedades crónicas más frecuentes de la infancia. Sin embargo, permanece subdiagnosticada y subtratada. Su prevalencia ha aumentado en los últimos años y varía del 2 % al 25 %. Los síntomas de la RA incluyen estornudos, prurito, rinorrea y congestión nasal. Un correcto diagnóstico y tratamiento de la RA y sus comorbilidades, tales como rinosinusitis con o sin poliposis nasal, conjuntivitis, otitis media, asma bronquial e infecciones del tracto respiratorio, son importantes para reducir el impacto negativo en la afectación de la calidad de vida del paciente y sus familiares, y los gastos sanitarios que ocasiona. La inmunoterapia alérgeno específica, en pacientes correctamente seleccionados, previene nuevas sensibilizaciones y reduce la hiperreactividad bronquial asociada a la RA. Considerando todos estos factores, el Comité Nacional de Alergia de la Sociedad Argentina de Pediatría propone recomendaciones basadas en la evidencia actual.


Allergic rhinitis (AR) is one of the most common chronic diseases in children. However, it remains underdiagnosed and undertreated. Its prevalence has increased in recent years and varies from 2 to 25 %. Symptoms include sneezing, itching, runny nose, and nasal congestion. A correct diagnosis and treatment of AR and its comorbidities such as rhinosinusitis with or without nasal polyposis, conjunctivitis, otitis media, bronchial asthma and respiratory tract infections, are important to reduce the negative impact on the quality of life of the patient and their relatives, and in medical costs. Specific allergen immunotherapy, in correctly selected patients, prevents new sensitizations and reduces bronchial hyperreactivity associated with AR. Taking into account all these reasons, the National Allergy Committee of the Sociedad Argentina de Pediatría proposes current evidence based recommendations

RESUMO

BACKGROUND AND OBJECTIVE: Chronic spontaneous urticaria (CSU) is a distressing disease. We report real-world data from the global Chronic Urticaria Registry (CURE) about associations between various CSU states and sleep impairment, plus important health-related quality-of-life (HRQoL) outcomes and compared different methods to assess CSU states. METHODS: CURE data were collected at baseline and 6-monthly follow-ups (FU). Assessments included CSU states using the Urticaria Control Test (UCT), weekly Urticaria Activity Score (UAS7), and Physician Global Assessment (PhyGA) of treatment response. Complete response to treatment (CR, UAS7 = 0), complete control of disease (CC, UCT = 16), and PhyGA = CR were assessed, plus the Dermatology Life Quality Index and the Chronic Urticaria Quality-of-Life Questionnaire (CU-Q2oL) sleep domain. RESULTS: Overall, 2078 patients were included. At baseline, 9.8%, 17.9%, and 42.3% of patients had UCT = 16, UAS7 = 0, or PhyGA = CR, respectively, which increased at FU1 and FU2. Patients with higher UCT scores had better sleep and HRQoL. The presence of angioedema without wheals, episodic disease, omalizumab treatment, and male sex were associated with CC (P < .05). Among 469 patients who achieved CC or CR, 16.4% (n = 77) showed CC or CR with all 3 instruments. Agreement between UCT = 16 and UAS7 = 0 measurements was moderate (κ = 0.581), but poor between UCT = 16 and PhyGA = CR (κ = 0.208). CONCLUSIONS: Few patients had CR/CC of their CSU at baseline entry. Disease control strongly related to good sleep and better HRQoL; therefore, it is important to aim for CR in CSU treatment. Patient-reported UCT and UAS7 assessments demonstrated a more accurate measurement of CSU state versus physician assessments.

RESUMO

OBJECTIVES: Hereditary angioedema (HAE) is a rare disease. During the last years, many studies and advances have been developed with the aim of better understanding the pathophysiology, as well as optimizing patient management. Several international working groups have attempted to clarify and standardize the care of HAE communicated as guidelines and consensus recommendations. We considered necessary to provide recommendations for the diagnosis and treatment of patients with HAE in Argentina. METHODS: A group of specialists of allergy and immunology from Argentina by using the online surveys methodology as well as face to face meetings developed the intended consensus. RESULTS: Recommendations were established based on published evidence and the expert opinion. The consensus focused on diagnosis, acute management of attacks, short and long-term prophylaxis, special situations (pediatrics and pregnancy) and disease management considering the health care system in Argentina. CONCLUSION: The recommendations established in this consensus guidelines will optimize the management of patients with HAE in Argentina.


Objetivos: El angioedema hereditario es una enfermedad poco frecuente. Durante los últimos años se han desarrollado muchas investigaciones y registrado avances con el objetivo de entender mejor la fisiopatología y optimizar la atención a los pacientes. Diversos grupos de trabajo internacionales han intentado clarificar y normalizar el cuidado de pacientes con angioedema hereditario, lo que se ha reflejado en guías y consensos. Consideramos necesario desarrollar un documento de consenso con recomendaciones para el diagnóstico y tratamiento del angioedema hereditario en Argentina. Metodología: Un grupo de expertos de Argentina, conformado por especialistas en Alergia e Inmunología mediante metodología de ronda de encuestas a distancia y reuniones presenciales llevó adelante la elaboración del consenso pretendido. Resultados: Se establecieron recomendaciones basadas en la evidencia publicada y en el criterio de los expertos participantes. Las recomendaciones se enfocaron en el diagnóstico, tratamiento y profilaxis de las crisis a corto y largo plazo, control de situaciones especiales y consideraciones del sistema de salud en Argentina. Conclusión: Las recomendaciones establecidas en este consenso permitirán optimizar la atención médica de los pacientes con angioedema hereditario en Argentina.

RESUMO

Despite the efforts made to mitigate the consequences of this disease, natural rubber latex allergy (NRLA) continues to be a global health problem and is still considered one of the main worries in the working environment in many countries throughout the world. Due to thousands of products containing latex, it is not surprising that the current statistics suggest that prevalence remains high among healthcare workers and susceptible patients. In developed countries, reduction in the prevalence of IgE-mediated allergy to latex proteins from gloves may lead to lax attention by health care personnel. On the other hand, this situation is different in developing countries where there is a lack of epidemiological data associated with a deficit in education and awareness of this issue. The aim of this review is to provide an update of the current knowledge and practical recommendations regarding NRLA by allergologists from different parts of the world with experience in this field.

RESUMO

La terapia de reemplazo enzimático disminuye la morbilidad y mejora la calidad de vida de los pacientes con mucopolisacaridosisii. Se han descrito reacciones de hipersensibilidad inmediata a este fármaco. La desensibilización es un tratamiento que induce la tolerancia temporaria a una droga y permite al paciente alérgico recibir la medicación.Se presenta el caso de un niño de 7 años con diagnóstico de síndrome de Hunter que, luego de 4 años de tratamiento con idursulfase, tuvo dos episodios de anafilaxia durante la infusión del fármaco. Se detectó inmunoglubulina E específica mediante pruebas cutáneas, y fue positiva la intradermorreacción con dilución 1/10 (0,2 mg/ml). Se realizó un protocolo de desensibilización de 12 pasos, sin presentar eventos adversos. La evaluación alergológica y la posibilidad de desensibilización constituyeron herramientas útiles en el manejo de nuestro paciente


Enzyme replacement therapy with idursulfase decreases morbidity and improves quality of life of patients with mucopolysaccharidosis ii. Immediate hypersensitivity reactions to this drug have been described. Desensitization is a treatment that induces temporary tolerance to a culprit drug, allowing the allergic patient to receive the medication.We present the case of a 7-year-old patient diagnosed with Hunter syndrome who presented, after 4 years of treatment, two episodes of anaphylaxis during the infusion of idursulfase. Detection of specific immunoglobulin E was carried out using skin tests, with intradermal reaction at a 1/10 dilution (0.2 mg/ml) being positive. A 12-step desensitization protocol was performed without presenting adverse events.The allergological evaluation and the possibility of desensitization were useful tools in the management of our patient.

RESUMO

The management of chronic urticaria (CU) has been controversial. Recently updated international guidelines propose evidence-based diagnosis and treatment. Nevertheless, dermatologists have heterogeneous approaches to managing CU. To estimate the percentage of dermatologists who have an optimal approach to CU according to the international guidelines, and to explore the variables associated with optimal management a cross-sectional study using a 17-question survey was delivered by email to dermatologists from Argentina. Optimal first, second, and third line treatment were considered when dermatologists chose a nonsedative antihistamine; increased the dosage of nonsedative antihistamines, and added omalizumab, respectively. Logistic regression was used to identify variables associated with optimal management. A total of 165 questionnaires were available for analysis. An optimal first, second, and third-line treatment approach was identified in 50%, 35%, and 15% of the dermatologists, respectively. The dermatologists' age being above 55 years old (OR: 0.12, 95% CI: 0.01-0.99, p .005) and having more than 5 years of expertise (OR: 0.4, 95% CI: 0.19-0.81, p .001) were significantly associated with a suboptimal approach in second-line treatment. We could not find variables associated with an optimal first or third-line treatment. The real-life management of CU in Argentina is partly suboptimal according to the international guidelines.

RESUMO

In recent years there has been a significant increase in the prevalence of allergic diseases despite advances in the understanding of the pathogenesis, the dissemination of guidelines for its management and the emergence of new drugs. The reasons for this increase are not fully established, but it is suggested that multiple environmental factors may be involved. Inhaled air contains numerous harmful agents in addition to environmental allergens. The main immediate respiratory clinical expression after inhaling this contaminated air is asthma and rhinitis. The activity of human beings has altered the outdoor environment by the emission of multiple pollutants and has produced an increasing climate change. It also has a notable impact on the development of respiratory pathology and the modification of air quality. The bibliography on the subject of environmental control is very broad and sometimes difficult to interpret. In order to be able to make precise, valid and simple indications for patients to accomplish with, four scientific societies of the Argentine Republic that deal with this type of diseases, have elaborated a document that contains information of easy access to all medical personal involved in the treatment of patients with asthma and / or rhinitis, that provides practical measures for the patients and the different public health systems about unmet needs in this complex issue.

La razón para este aumento no está totalmente establecida, pero se considera que múltiples factores ambientales podrían estar involucrados en ello. El aire inspirado contiene numerosos agentes nocivos además de alérgenos ambientales; el asma y la rinitis alérgica son las principales expresiones clínicas respiratorias inmediatas posteriores a su inhalación. En la antropósfera, el entorno de la superficie terrestre habitada por los humanos, se han alterado los equilibrios naturales por la emisión de múltiples sustancias y se ha producido un creciente cambio climático. Este fenómeno global influye en la calidad del aire y consecuentemente en el desarrollo de enfermedades respiratorias. Dado que la bibliografía sobre el tema del control ambiental es muy amplia, y en ocasiones difícil de interpretar para poder realizar indicaciones precisas, válidas y sencillas de cumplir por parte de los pacientes, cuatro sociedades científicas de la República Argentina, dedicadas a este tipo de enfermedades, elaboraron un documento con información de fácil acceso a todo profesional médico que trate asma y/o rinitis, que expone medidas prácticas para los enfermos y alerta a los distintos actores involucrados en la salud pública acerca de las necesidades insatisfechas en este tema tan complejo, a fin de poder elaborar una agenda para su posible resolución.

RESUMO

La alergia a la proteína de la leche de vaca (APLV) es la alergia alimentaria más frecuente en pediatría. Existen pocos estudios que han evaluado la prevalencia de esta enfermedad en Argentina. Objetivos. Estimar la prevalencia de la APLV y describir su variación durante un período de 11 años. Pacientes y métodos. Se realizó un estudio de cohorte retrospectivo en recién nacidos vivos pertenecientes al programa de atención médica de un hospital universitario de comunidad. Resultados. Se identificaron 116 casos de niños con APLV. La prevalencia acumulada fue de 0,8% (intervalo de confianza -le- 95%: 0,65-0,95). Se observó un incremento porcentual de casos por año, de 0,4% en 2004 a 1,2% en 2014. Conclusión. La prevalencia de APLV fue del 1,2% en 2014, tres veces superior a la prevalencia en 2004.


Cow's milk protein allergy (CMPA) is the most common food allergy in pediatrics. In Argentina, the prevalence of this dis-ease has been evaluated in a few trials.Objectives. To estimate the prevalence of CMPA and describe its variation throughout a period of 11 years.Population and methods. A retrospective cohort study was carried out in live newborn infants enrolled in a health care program of a university community hospital.Results. One hundred and sixteen cases of children with CMPA were identified. Cumulative prevalence was 0.8% (95% confi-dence interval [CI]: 0.65-0.95). A percent increase of 0.4% in 2004 to 1.2% in 2014 was observed in the number of cases per year.Conclusion. In 2014, CMPA prevalence was 1.2%, i.e. three times that of 2004.

RESUMO

PURPOSE OF REVIEW: Since omalizumab has been approved for urticaria, numerous randomized and real-life observational trials have been published. We reviewed the period January 2017-February 2018. RECENT FINDINGS: Omalizumab is effective for the control of urticaria recalcitrant to antihistamines in different populations globally. The ratio of total serum IgE 4-week/baseline ≥2 can predict response with a high likelihood. In observational real-life trials, doses have been adjusted on an individual basis: in some populations, up to two-thirds of the patients can be controlled with 150 mg/month; however, others are still not controlled with 300 mg/month. In these, 150 mg bimonthly could be tried, before up-dosing to 450 mg/month. On the long run (up to 3 years) omalizumab kept its efficacy. In many patients, dosing intervals could be augmented (6-8 weeks, some even more). After a 12-month treatment, about 20% showed long-term remission without relapse. Some biomarkers are being detected. Adjusting omalizumab doses in urticaria patients could enhance efficacy (shortening dosing interval and/or augmenting dose) and save costs (after 12 months: extending dosing interval and/or reducing dose).

Introduction. Latex allergy is common in the hospital setting. Objective. To describe the clinical situation of three pediatric interns with latex allergy and the prevention strategies implemented during clinical clerkships in pediatric and neonatal intensive care units. Patients, methods, and outcomes. The three interns referred symptom exacerbation during their internship program. Diagnosis was confirmed based on a compatible history and positive specific immunoglobulin E. A semi-structured interview was done to describe perceptions about prevention strategies, the personnel were trained, and nitrile gloves were provided for carrying out procedures. Interns completed their clinical clerkships without having allergic reactions. Positive aspects referred by interns were that they felt cared for and experienced an improved quality of life; negative aspects were a bad predisposition and resistance against change among some other interns. Strategies designed to this end permitted interns to continue their internship program.

RESUMO

Introducción. La alergia a la proteína de la leche de vaca es la alergia alimentaria más frecuente en pediatría. El subtipo de las mediadas por inmunoglobulina E (IgE) presenta mayor riesgo de vida y peor pronóstico. Objetivos. Describir la evolución de la alergia a la proteína de la leche de vaca mediada por IgE y los factores de riesgo asociados a la persistencia de la enfermedad. Pacientes y método. Estudio descriptivo, retrospectivo en pacientes que consultaron a la sección de Alergia Pediátrica del Hospital Italiano entre junio de 2006 y junio de 2012 con diagnóstico de alergia a la leche de vaca mediada por IgE. Resultados: Se hallaron 72 pacientes con alergia a la leche de vaca mediada por IgE, 39 (54%) de sexo masculino. La edad promedio al momento del diagnóstico fue de 5,19 ± 3,7 meses; los síntomas de presentación más frecuentes fueron urticaria y vómitos. La rinitis y el asma fueron las enfermedades atópicas concomitantes más frecuentemente observadas. En el período de estudio, el 54,5% adquirieron tolerancia a la edad promedio de 32 meses. La presencia de pápulas mayores de 8mm en el prick test y de sensibilización a la caseína se asoció con la persistencia de la enfermedad. Conclusión. El 54,5% de los pacientes desarrolló tolerancia a los 32 meses de vida. Se encontró una asociación significativa entre el tamaño de la pápula al momento del diagnóstico y la sensibilización a la caseína con la persistencia de la enfermedad.


Introduction. Cow's milk protein allergy is the most common allergy in pediatrics. Immunoglobulin E (IgE)-mediated cow's milk allergy poses a higher risk for life and a worse prognosis. Objectives. To describe the course of IgE-mediated cow's milk protein allergy and risk factors associated with disease persistence. Patients and methods. This was a descriptive, retrospective study conducted in patients seen at the Division of Pediatric Allergy of Hospital Italiano between June 2006 and June 2012 who had been diagnosed with IgE-mediated cow's milk allergy. Results. Out of the 72 patients with IgE-mediated cow's milk allergy, 39 (54%) were boys. Patients' average age at the time of diagnosis was 5.19 ± 3.7 months old; the most common symptoms were urticaria and vomiting. Rhinitis and asthma were the most commonly observed concomitant atopic diseases. In the study period, 54.5% of patients developed tolerance at an average age of 32 months old. An 8-mm papule in the skin prick test and casein sensitization were associated with disease persistence. Conclusion. Overall, 54.5% of patients developed tolerance at 32 months old. A significant association was observed between papule size at the time of diagnosis and casein sensitization and disease persistence.

RESUMO

INTRODUCTION: Latex allergy is one of the main reasons of anaphylaxis in the operating room. The prevalence of this condition is higher among patients with myelomeningocele. Epidemiological data obtained from Argentine patients is scarce. OBJECTIVE: To estimate the prevalence of latex sensitivity and latex allergy in a population of patients with myelomeningocele and to describe associated risk factors. POPULATION AND METHODS: Descriptive, cross-sectional, observational study. Family and personal history of allergy, number of surgeries, history of symptoms caused by having been in contact with latex or cross-reactive foods, eosinophil count, measurement of total immunoglobulin E and specific immunoglobulin E levels by means of skin and serologic testing for latex, aeroallergens and cross-reactive fruit. RESULTS: Eighty-two patients diagnosed with myelomeningocele were assessed: 41 were males and their average age was 15.3 ± 7.66 years old. Out of all patients, two did not complete skin and serologic testing. Among the remaining 80 patients, 16 (19.51%) had latex allergy, 46 (57.5%) were not allergic, and 18 (22%) showed sensitivity but not allergy. Having undergone more than five surgeries was a risk factor associated with latex allergy (p= 0.035). No significant association was observed with the remaining outcome measures. CONCLUSION: According to this study, the prevalence of latex allergy in this population of patients is 19.51% and the most important risk factor for this condition is a history of having undergone more than five surgeries.


INTRODUCCIÓN: La alergia al látex se encuentra dentro de las primeras causas de anafilaxia en el quirófano. La prevalencia de esta enfermedad es más elevada en pacientes con mielomenigocele. Existen escasos datos epidemiológicos en pacientes argentinos. OBJETIVO: Estimar la prevalencia de la sensibilidad y de la alergia al látex en una población de pacientes con mielomeningocele y describir los factores de riesgo asociados. PACIENTES Y MÉTODOS: Estudio descriptivo, transversal, observacional. Se analizaron los antecedentes familiares y personales de alergia, el número de procedimientos quirúrgicos, la historia de síntomas ante el contacto con látex o alimentos con reactividad cruzada, el recuento de eosinófilos, la inmunoglobulina E total y la inmunoglobulina E específica mediante pruebas serológicas y cutáneas para el látex, los aeroalérgenos y las frutas con reactividad cruzada. RESULTADOS: Se evaluaron 82 pacientes con diagnóstico de mielomeningocele, 41 del sexo masculino (50%), con edad promedio de 15,3 ± 7,66 años. Del total de los pacientes, 2 no realizaron las pruebas cutáneas y serológicas. De los 80 restantes, 16 (19,51%) presentaban alergia al látex, 46 (57,5%) no eran alérgicos y 18 (22%) fueron sensibles pero no alérgicos. Se observó que haber tenido más de 5 cirugías representaba un factor de riesgo asociado a alergia al látex (p= 0,035). No se encontró una asociación significativa con el resto de las variables evaluadas. CONCLUSION: El estudio estima que la prevalencia de alergia al látex en esta población de pacientes es de 19,51% y que el factor de riesgo más importante para el desarrollo de esta patología es el antecedente de haber sido sometido a más de 5 intervenciones.
