Uncontrolled severe T2 asthma: Which biological to choose? A biomarker-based approach.

In recent years, advances in knowledge of molecular mechanisms involved in asthma have changed uncontrolled severe asthma (USA) treatment, with the appearance of biological treatment. USA is a heterogeneous entity with different endotypes and phenotypes. Nowadays, the biological drugs approved with asthma indication are omalizumab, mepolizumab, reslizumab, benralizumab and dupilumab. Tezepelumab is approved by the Food and Drug Administration (FDA) in the United States and, recently, by the European Medicines Agency (EMA). All these biological drugs have shown their efficacy in clinical trials, especially in reducing exacerbations, improving asthma control, quality of life, pulmonary function, and withdrawing systemic corticosteroids or at least reducing their daily dose, with some differences between them. Except for mepolizumab and reslizumab, biological drugs have different targets and thus different therapeutic indications should be expected; however, in some patients, more than one drug could be indicated, making the election more difficult. Because there are no direct comparisons between biological drugs, some biomarkers are used to choose between them, but they are not unbeatable. In this article, an algorithm to choose the first biological drug in a specific patient is proposed based on different study results and patient' characteristics.

Effectiveness of Text Message Reminders on Adherence to Inhaled Therapy in Patients With Asthma: Prospective Multicenter Randomized Clinical Trial.

BACKGROUND: Poor adherence to inhaled medication in asthma patients is of great concern. It is one of the main reasons for inadequate asthma control. OBJECTIVE: The goal of the research was to determine if motivational messages using short message service (SMS, or text) improved adherence to inhaled medication in patients with asthma. METHODS: A prospective multicenter randomized parallel-group clinical trial was conducted in 10 asthma clinics in Spain. Adherence was assessed with electronic monitors (Smartinhaler, Adherium Ltd) connected to inhalers. Patients in the SMS group received psychologist-developed motivational messages every 3 days for 6 months. RESULTS: There were 53 patients in the SMS group and 88 patients in the control group. After 6 months, mean electronic adherence was 70% (SD 17%) in the intervention group and 69% (SD 17%) in the control group (P=.82). Significant differences between the study groups in morning and evening adherence to inhaled therapy, asthma control, exhaled nitric oxide levels, or improvement of lung functions were not observed. CONCLUSIONS: Motivational messages were not useful to improve adherence to inhaled asthma medication compared with usual care.

Recomendaciones de derivación del paciente adulto con crisis de asma desde el servicio de urgencias / Referral recommendations for adult emergency department patients with exacerbated asthma

El presente documento de consenso se ha desarrollado con el fin de proporcionar una herramienta útil para el manejo del paciente asmático que acude al servicio de urgencias (SU) con una crisis asmática. Incluye recomendaciones para tomar la decisión de alta o ingreso, así como indicaciones de derivación para el posterior seguimiento. Un equipo multidisciplinar, constituido por tres especialistas en medicina de urgencias, tres especialistas en neumología y tres especialistas en alergología, se encargó de elaborar una lista de preguntas clínicas que respondieron mediante la ayuda tanto de guías de práctica clínica, como de literatura disponible. Los contenidos y el reparto de tareas en diferentes grupos de trabajo se consensuaron en una reunión presencial. Los materiales resultantes se pusieron en común y sirvieron para la preparación del manuscrito final. Las recomendaciones y los algoritmos incluidos en el mismo van dirigidos a identificar y diagnosticar correctamente las exacerbaciones asmáticas en el SU y a establecer los criterios de hospitalización o alta. Se incluyen también las pautas para el tratamiento de los pacientes y para su derivación al ámbito de atención especializada en caso de alta, incluyendo los criterios de priorización para dicha derivación. El documento ha sido avalado por la Sociedad Española de Neumología y Cirugía Torácica (SEPAR), Sociedad Española de Alergología e Inmunología Clínica (SEAIC), y la Sociedad Española de Urgencias y Emergencias (SEMES)

This consensus paper's purpose is to provide a tool for managing emergency asthma exacerbations that require a decision to admit or discharge the patient. The paper also addresses where to refer the discharged patient for follow up. A multidisciplinary team of 3 emergency physicians, 3 specialists in respiratory medicine, and 3 allergy specialists were charged with drafting a list of clinical questions to answer by consulting practice guidelines and other resources in the literature. The specialists held a face-to-face meeting to distribute tasks and topics to working groups. The groups shared their reports, which provided the basis for drafting the final paper. The recommendations and flow charts included in the paper provide guidance for identifying and correctly diagnosing asthma exacerbations in the emergency department. Criteria for admission or discharge are incorporated. Treatment protocols and recommendations for referring discharged patients to specialists are addressed, along with criteria for priority referrals. The final consensus paper has been endorsed by the Spanish Society of Pulmonology and Thoracic Surgery (SEPAR), the Spanish Society of Allergology and Clinical Immunology (SEAIC), and the Spanish Society of Emergency Medicine (SEMES)

Mucus hypersecretion in asthma is associated with rhinosinusitis, polyps and exacerbations.

BACKGROUND: Bronchial hypersecretion is a poorly studied symptom in asthma. The aim of the study was to determine the specific characteristics of asthmatics with bronchial hypersecretion. METHODS: A total of 142 asthmatics (21.8% men; mean age 49.8 years) were prospectively followed for one year. Mucus hypersecretion was clinically classified into two severity categories: daily sputum production and frequent expectoration but not every day. Clinical and pulmonary function variables associated with mucus hypersecretion were assessed by multiple logistic regression analysis. RESULTS: Daily cough was recorded in 28.9% of patients and sputum production daily or most of the days in 52.1%. Patients with mucus hypersecretion had more dyspnoea, poorer asthma control and quality of life, had suffered from more exacerbations and showed anosmia associated with chronic rhinosinusitis and nasal polyposis more frequently. Factors associated to mucus hypersecretion were anosmia, one exacerbation or more in the previous year and FEV1/FVC <70% (AUC 0.75, 95% CI 0.66-0.85) for the first definition of hypersecretion, and anosmia, poor asthma control and age (AUC 0.75, 95% CI 0.67-0.83) for the second definition. CONCLUSIONS: Mucus hypersecretion is frequent in patients with asthma, and is associated with chronic upper airways disease, airway obstruction, poor asthma control and more exacerbations.

Consenso sobre el solapamiento de asma y EPOC (ACO) entre la Guía española de la EPOC (GesEPOC) y la Guía Española para el Manejo del Asma (GEMA) / Consensus on the Asthma-COPD Overlap Syndrome (ACOS) Between the Spanish COPD Guidelines (GesEPOC) and the Spanish Guidelines on the Management of Asthma (GEMA)

A instancias de la Sociedad Española de Neumología y Cirugía Torácica (SEPAR), promotora de la Guía española de la EPOC (GesEPOC) y de la Guía Española para el Manejo del Asma (GEMA), autores de ambas guías han unificado criterios diagnósticos del solapamiento asma y EPOC (Asthma-COPD Overlap [ACO]). Este consenso define al ACO como la coexistencia en un mismo paciente de tres elementos: tabaquismo, limitación crónica al flujo aéreo y asma. La confirmación diagnóstica se establece cuando un paciente ( 35 años) fumador o exfumador ( 10 paquetes-año) presenta obstrucción o limitación crónica al flujo aéreo (FEV1/FVC post-broncodilatador < 70%), que persiste tras tratamiento broncodilatador y esteroideo inhalado (incluso oral en casos seleccionados) y diagnóstico objetivo de asma actual (según criterios GEMA). En los casos en los que este último no se pueda establecer, se aceptará una prueba broncodilatadora espirométrica muy positiva (FEV1 15% y 400 ml) o una elevada eosinofilia en sangre ( 300 eosinófilos/ l). Se solicitó la opinión (mediante encuesta Delphi modificada) a otros 33 expertos que no habían participado en la elaboración del consenso. Un 80% de estos lo valoró positivamente, incluso superior a otras propuestas recientes. El consenso GesEPOC-GEMA sobre ACO proporciona una visión unitaria del problema, con una propuesta conceptual sencilla y un algoritmo diagnóstico pragmático, aplicable en cualquier nivel sanitario de nuestro ámbito (AU)

Following a proposal by the Spanish Society of Pulmonology and Thoracic Surgery (SEPAR), sponsor of the Spanish COPD Guidelines (GesEPOC) and the Spanish Guidelines on the Management of Asthma (GEMA), authors of both papers have unified the criteria for the diagnosis of asthma-COPD overlap syndrome (ACOS). This consensus defines ACOS as the presence in a given patient of three elements: significant smoking exposure, chronic airflow limitation and asthma. Diagnosis is confirmed when a patient (35 years of age or older), smoker or ex-smoker of more than 10 pack-years, presents airflow limitation (post-bronchodilator FEV1/FVC < 0.7) that persists after treatment with bronchodilators and inhaled corticosteroids (even after systemic corticosteroids in selected cases), and an objective current diagnosis of asthma (according to GEMA criteria). In cases in which the diagnosis of asthma cannot be demonstrated, marked positive results on a bronchodilator test (FEV1 15% and 400 mL) or elevated blood eosinophil count ( 300 eosinophils/ L) will also be diagnostic of ACOS. The opinion of another 33 experts who had not participated in the consensus was sought using a modified Delphi survey. Up to 80% of respondents gave a very positive opinion of the consensus, and declared that it was better than other previous proposals. The GesEPOC-GEMA consensus on ACOS provides a unique perspective of the diagnostic problem, using a simple proposal and a pragmatic diagnostic algorithm that can be applied at any healthcare level (AU)

Multidisciplinary Consensus on the Nonadherence to Clinical Management of Inhaled Therapy in Spanish asthma patients.

PURPOSE: Rates of nonadherence to asthma treatment in Spain are between 24% and 76%, which results in poor disease control and increased health care costs. The main objective of this multidisciplinary consensus was to investigate the opinions of health professionals and patients regarding adherence to inhaled therapy in Spain. The results will help to identify the causes of nonadherence and to establish strategies to detect and correct the problem. METHODS: This research was conducted by using a modified Delphi method organized into 2 rounds and involving a panel of 64 physicians, 16 nurses, and 10 community pharmacists. In addition, 70 patients with asthma completed a simplified 1-round survey, based on the Delphi questionnaire. The items proposed to reach a consensus included topics such as impact and causes of nonadherence, as well as strategies to improve adherence to treatment. FINDINGS: Expert panelists reached a consensus on ~80% of the items proposed. They agreed that the lack of control in asthma has an important economic impact. The causes of nonadherence with more agreement were the patients' beliefs about treatment and the complexity of the inhalation devices. Panelists agreed that the most important strategies to improve adherence were modification of patients' beliefs, training of professionals in the management of adherence, and personalization of interventions. Most patients only agreed with items that referred to strategies to improve adherence. IMPLICATIONS: Although the problems, impact, causes, and interventions regarding nonadherence to asthma treatment are known, adequate monitoring of adherence to treatment is not performed. A multidisciplinary and personalized approach is necessary to control and improve adherence.
