Antecedentes y objetivo Es bien sabido que las terapias biológicas reducen las exacerbaciones y mejoran el tratamiento del asma grave no controlada. La administración domiciliaria de biológicos ha aumentado durante la pandemia de COVID-19, pero aún no se han identificado las características de los pacientes con asma grave no controlada que pueden beneficiarse de la administración domiciliaria de terapia biológica. Materiales y métodos Este proyecto se basa en la metodología Delphi, diseñada para alcanzar un consenso entre expertos a través de un comité científico multidisciplinar que aborda las siguientes cuestiones: características clínicas, adherencia al tratamiento, capacidad de administración del paciente o cuidador, autocuidado del paciente, relación con el profesional sanitario, preferencias del paciente y acceso al hospital. Resultados Ciento treinta y un profesionales sanitarios (neumólogos, alergólogos, enfermeros y farmacéuticos hospitalarios) cumplimentaron las dos rondas de consenso del cuestionario Delphi. Se identificaron 14 ítems como características prioritarias, siendo los cinco primeros: 1. El paciente sigue las indicaciones/recomendaciones del equipo sanitario para controlar su enfermedad. 2. El paciente es capaz de detectar cualquier deterioro de su enfermedad y de identificar los factores desencadenantes de las exacerbaciones. 3. El paciente recibe tratamiento biológico y tiene una enfermedad estable sin riesgo vital. 4. El paciente se responsabiliza de su autocuidado y 5. el paciente tiene obligaciones laborales/educativas que le impiden acudir al hospital con regularidad (AU)
Background and objective Biologic therapies are known to reduce exacerbations and improve severe uncontrolled asthma management. The at-home administration of biologics has increased during the COVID-19 pandemic, but the characteristics of severe uncontrolled asthma patients who may benefit from at-home administration of biologic therapy have yet to be identified. Materials and methods This project is based on the Delphi method, designed to reach an expert consensus through a multidisciplinary scientific committee addressing the following questions: clinical characteristics, treatment adherence, patient or caregiver administration ability, patient self-care, relationship with the healthcare professional, patient preference, and access to the hospital. Results One hundred and thirty-one healthcare professionals (pulmonologists, allergists, nurses, and hospital pharmacists) completed two Delphi consensus questionnaires. Fourteen items were identified as priority characteristics, the first five being: 1. The patient follows the healthcare team's indications/recommendations to control their disease, 2. The patient is capable of detecting any deterioration in their disease and of identifying exacerbation triggers, 3. The patient receives biologic therapy and has stable disease with no vital risk, 4. The patient takes responsibility for their self-care, 5. The patient has occupational/educational obligations that prevent them from going to the hospital regularly. Conclusions Disease stability and control plus the ability to identify exacerbation triggers are the most important characteristics when opting for at-home administration for a patient with severe uncontrolled asthma on biologic therapy. These recommendations could be applicable in clinical practice (AU)

BACKGROUND AND OBJECTIVE: Comorbidities can influence asthma control and promote asthma exacerbations (AEs). However, the impact of multimorbidity in AEs, assessed based on long-term follow-up of patients with asthma of different degrees of severity, has received little attention in real-life conditions. To describe the epidemiological and clinical characteristics and predictors of AEs in patients who had presented at least 1 AE in the previous year in the MEchanism of Genesis and Evolution of Asthma (MEGA) cohort. METHODS: The work-up included a detailed clinical examination, pulmonary function testing, fractional exhaled nitric oxide (FeNO), blood counts, induced sputum, skin prick-tests, asthma questionnaires, and assessment of multimorbidity. The number of moderate-severe AEs in the preceding year was registered for each patient. RESULTS: The study population comprised 486 patients with asthma (23.7% mild, 35% moderate, 41.3% severe). Disease remained uncontrolled in 41.9%, and 47.3% presented ≥1 moderate-severe AE, with a mean (SD) annual exacerbation rate of 0.47 (0.91) vs 2.11 (2.82) in mild and severe asthma, respectively. Comorbidity was detected in 56.4% (66.6% among those with severe asthma). Bronchiectasis, chronic rhinosinusitis with nasal polyps, atopy, psychiatric illnesses, hyperlipidemia, and hypertension were significantly associated with AEs. No associations were found for FeNO, blood eosinophils, or total serum IgE. Sputum eosinophilia and a high-T2 inflammatory pattern were significantly associated with AEs. Multivariable regression analysis showed a significant association with asthma severity, uncontrolled disease, and low prebronchodilator FEV1/FVC. CONCLUSION: Our study revealed a high frequency of AE in the MEGA cohort. This was strongly associated with multimorbidity, asthma severity, poor asthma control, airflow obstruction, higher sputum eosinophils, and a very high-T2 inflammatory pattern.

BACKGROUND AND OBJECTIVES: Chronic rhinosinusitis with nasal polyps (CRSwNP), which is characterized by partial loss of smell (hyposmia) or total loss of smell (anosmia), is commonly associated with asthma and/or nonsteroidal anti-inflammatory drug-exacerbated respiratory disease (N-ERD). CRSwNP worsens disease severity and quality of life. The objective of this real-world study was to determine whether biological treatments prescribed for severe asthma can improve olfaction in patients with CRSwNP. A further objective was to compare the improvement in in olfaction in N-ERD and non-N-ERD subgroups. METHODS: We performed a multicenter, noninterventional, retrospective, observational study of 206 patients with severe asthma and CRSwNP undergoing biological treatment (omalizumab, mepolizumab, benralizumab, or reslizumab). RESULTS: Olfaction improved after treatment with all 4 monoclonal antibodies (omalizumab [35.8%], mepolizumab [35.4%], reslizumab [35.7%], and benralizumab [39.1%]), with no differences between the groups. Olfaction was more likely to improve in patients with atopy, more frequent use of short-course systemic corticosteroids, and larger polyp size. The proportion of patients whose olfaction improved was similar between the N-ERD (37%) and non-N-ERD (35.7%) groups. CONCLUSIONS: This is the first real-world study to compare improvement in olfaction among patients undergoing long-term treatment with omalizumab, mepolizumab, reslizumab, or benralizumab for severe asthma and associated CRSwNP. Approximately 4 out of 10 patients reported a subjective improvement in olfaction (with nonsignificant differences between biologic drugs). No differences were found for improved olfaction between the N-ERD and non-N-ERD groups.

La rinosinusitis crónica con poliposis nasal (PN), caracterizada por la pérdida parcial o completa del olfato (hiposmia o anosmia, respectivamente), se asocia frecuentemente a asma y a enfermedad respiratoria exacerbada por ácido acetilsalicílico (EREA), lo cual implica una mayor gravedad y un deterioro adicional de la calidad de vida del paciente. Objetivos: El objetivo principal de este estudio fue determinar, en condiciones de vida real, si los tratamientos biológicos prescritos para asma grave mejoraban el olfato en aquellos pacientes que asociaban PN. Como objetivo secundario, se comparó la mejoría del olfato entre los subgrupos EREA y no EREA. Métodos: Se llevó a cabo un estudio multicéntrico, observacional, retrospectivo, que incluyó 206 pacientes con PN y asma grave en tratamiento con algún biológico (omalizumab, mepolizumab, benralizumab oreslizumab). Resultados: Se encontró mejoría del olfato con todos los biológicos: omalizumab (35,8%), mepolizumab (35,4%), reslizumab (35,7%) y benralizumab (39,1%), sin diferencias estadísticamente significativas entre ellos. Los pacientes con atopia, mayor uso de corticoides sistémicos y mayor tamaño de PN inicial, presentaron mayor mejoría. La proporción de pacientes que presentaron mejoría en el olfato fue similar entre el grupo EREA (37%) y no EREA (35,7%). Conclusiones: Se trata del primer estudio que compara, en condiciones de vida real, la mejoría del olfato en pacientes en tratamiento con omalizumab, mepolizumab, reslizumab o benralizumab indicados por asma grave que asociaban PN. Aproximadamente, 4 de cada 10 pacientes refirió mejoría subjetiva en el olfato (sin diferencias estadísticamente significativas entre los distintos biológicos). No se encontraron diferencias entre el grupo EREA y no EREA (AU)

Introduction: Allergic rhinitis (AR) is a clinical syndrome characterized by IgE-mediated inflam-mation of the nasal mucosa. The present study investigates the quality of life (QoL) with AR among adults, using widely validated questionnaires, unlike in pediatric patients.Materials and methods: A cross-sectional descriptive observational study was conducted, analyzing the QoL of 102 children with AR aged between 10-15 years, belonging to two health centers (HC) in Zaragoza and two HC in Coruña. The comparison of means between the two groups is carried out using the Student's test or the Mann-Whitney test, considering a value of p<0.05 to be significant.Results: Around 102 children were studied, with a majority (59.8%) being male and a mean age of 12 years. Around 76.5% have a family history of atopy. It was found that AR is more prevalent in Zaragoza (p <0.005), and asthmais highly prevalent in Coruña (p <0.001). The most import-ant sensitizations are pollen in Zaragoza (p <0.05) and dust mites in A Coruña (p <0.001). More treatment needs and associated comorbidities (p<0.05) were observed in A Coruña. The results of the ESPRINT-15 show that 63% of the patients have a good QoL, 27% fair, and 8.8%, poor. Those sensitized to mites have a worse score (p = 0.02). It was found that 52% of children expe-rienced improvement during home confinement, with no notable differences between the two populations. The use of the mask favored QoL in patients from Zaragoza (p <0.0 01 (AU)

PURPOSE OF REVIEW: To critically examine evidence suggesting that food allergy induced by lipid transfer proteins (LTPs) follows a geographic pattern. RECENT FINDINGS: LTP syndrome remains most common in the Mediterranean basin, with a clear gradient seen in prevalence of LTP sensitization between northern and southern Europe. We hypothesize that high levels of birch pollen seem to protect against LTP allergy, as these higher levels correlate with a lower prevalence of LTP hypersensitivity. Nevertheless, LTP food allergy cases still appear in areas having a high environmental level of birch pollen. Food allergy caused by LTP may be related to (1) primary sensitization to a food LTP allergen in the absence of pollinosis, (2) primary sensitization to LTP from a pollen source, and (3) co-sensitization to LTP from pollen and food.

Epidemiological surveillance provides updated information about health problems which allows for the establishment of health policy guidelines. The methods for detecting the epidemic frequency of disease require the systematic collection of data on the occurrence of specific diseases. Influenza has cyclic seasonal peaks and its endemic baseline rates are useful for identifying outbreaks: the comparison between baseline and current data supplies epidemiological evidence related to an ongoing outbreak. The upper and lower incidence curves were traced for the data referring to IA detection in the nasopharyngeal aspirates from children hospitalized for acute lower respiratory tract infection from 1996 to 2002. The arithmetic mean and the 95% confidence interval for upper and lower limits of weekly incidence were calculated. The highest incidence was observed between weeks 25 and 32. When analyzing the prepared endemic corridor, it was observed that the highest detection in 2003 occurred between weeks 19 and 25, whereas two peaks occurred in 2004, the first starting at week 20, at a lower level than the normal epidemic peak, and the second at week 26.

La vigilancia epidemiológica provee información actualizada y oportuna sobre los problemas de salud y sus condicionantes, lo que permite definir acciones de prevención y control. Para la detección de epidemias es útil disponer de corredores endémicos, que indican el número de casos esperados para un cuadro infeccioso en un momento determinado. Con datos de la sección Microbiología del Hospital de Niños "Dr. Pedro de Elizalde" acerca de pacientes internados con diagnóstico de infección respiratoria aguda baja (IRAB) entre el 1/1/96 y el 31/12/2002 se confeccionaron los corredores para influenza A (IA) por semanas epidemiológicas, correspondientes a un período de siete años. En ese período se internaron 10.473 niños con diagnóstico de IRAB y se identificó IA en 411 aspirados nasofaríngeos. Se calcularon la media y el intervalo de confianza de 95% para los límites superior e inferior de incidencia en períodos semanales, y se encontró que el pico estacional ocurre entre las semanas 25 y 32. Al analizar los datos del año 2003, se observó que el pico se produjo antes, entre las semanas 19 y 25, y con valores muy por encima de los esperados para esas semanas. En 2004 aparecen 2 picos, el primero en la semana 20 y sin superar los valores de fluctuación de la parte central de la curva, y el segundo en la semana 26.

Candida spp. colonization in neonates occurs due to vertical or horizontal transmission. Preliminary studies determined that Candida albicans is the principal agent of these infections. In order to establish nosocomial transmission, 26 Candida albicans strains isolated from patients with candidosis hospitalized during a 18-month period in 2 neonatal intensive care units (NICU) from a pediatric hospital were studied. Fourteen isolates from patients and health care workers, involved in possible outbreaks of an intensive care unit (UCI) and a NICU from another pediatric hospital were also studied. All Candida albicans strains were genotyped by Southern blot hybridization with 27A. Isolates for outbreak confirmation were also hybridized with another specific Candida albicans probe, Ca3. Hybridization patterns demonstrated horizontal transmission in all the units studied. In a NICU, transmission among 4 patients during a 10-month period could be established and in the other NICU, 3 cases of transmission among 2 patients each were demonstrated in periods of 2 to 20 days. The outbreak studies showed the same strain isolated from 2 nurses and from one patient at the NICU and at the ICU identical strains were found in 3 patients. In this study, hybridization with Ca3 in addition to 27A probe did not increase discrimination power among isolates. Genotypic analysis allows, not only, determination of transmission and persistence of strains during prolonged periods or in sporadic outbreaks, but also facilitates necessary epidemiological decisions for optimizing nosocomial fungal infection control measures.
