Allergic Rhinitis and its Impact on Asthma (ARIA) Phase 4 (2018): Change management in allergic rhinitis and asthma multimorbidity using mobile technology.

Allergic Rhinitis and its Impact on Asthma (ARIA) has evolved from a guideline by using the best approach to integrated care pathways using mobile technology in patients with allergic rhinitis (AR) and asthma multimorbidity. The proposed next phase of ARIA is change management, with the aim of providing an active and healthy life to patients with rhinitis and to those with asthma multimorbidity across the lifecycle irrespective of their sex or socioeconomic status to reduce health and social inequities incurred by the disease. ARIA has followed the 8-step model of Kotter to assess and implement the effect of rhinitis on asthma multimorbidity and to propose multimorbid guidelines. A second change management strategy is proposed by ARIA Phase 4 to increase self-medication and shared decision making in rhinitis and asthma multimorbidity. An innovation of ARIA has been the development and validation of information technology evidence-based tools (Mobile Airways Sentinel Network [MASK]) that can inform patient decisions on the basis of a self-care plan proposed by the health care professional.

ARIA pharmacy 2018 "Allergic rhinitis care pathways for community pharmacy": AIRWAYS ICPs initiative (European Innovation Partnership on Active and Healthy Ageing, DG CONNECT and DG Santé) POLLAR (Impact of Air POLLution on Asthma and Rhinitis) GARD Demonstration project.

Pharmacists are trusted health care professionals. Many patients use over-the-counter (OTC) medications and are seen by pharmacists who are the initial point of contact for allergic rhinitis management in most countries. The role of pharmacists in integrated care pathways (ICPs) for allergic diseases is important. This paper builds on existing studies and provides tools intended to help pharmacists provide optimal advice/interventions/strategies to patients with rhinitis. The Allergic Rhinitis and its Impact on Asthma (ARIA)-pharmacy ICP includes a diagnostic questionnaire specifically focusing attention on key symptoms and markers of the disease, a systematic Diagnosis Guide (including differential diagnoses), and a simple flowchart with proposed treatment for rhinitis and asthma multimorbidity. Key prompts for referral within the ICP are included. The use of technology is critical to enhance the management of allergic rhinitis. However, the ARIA-pharmacy ICP should be adapted to local healthcare environments/situations as regional (national) differences exist in pharmacy care.

[Successful oral desensitization to levothyroxine. Report of one case]. / Desensibilización a levotiroxina. Caso clínico.

We report a 39-year-old female who underwent a total thyroidectomy as treatment for a thyroid papillary cancer. She suffered several episodes of mild angioedema in lips and tongue, after using different commercial Levothyroxine formulations, with and without excipients. Given the need to use this drug, the patient was admitted in our hospital and we proceeded to desensitize her with oral Levothyroxine. The patient fasted throughout the whole procedure, was properly monitored and had an adequate peripheral venous access. On the first day of the procedure, a 15-step protocol was performed, first administering placebo and then, compounded formulations of Levothyroxine starting from 0.01 ug, followed by doubling doses every 15 minutes until the cumulative dose of 111.95 ug was completed, corresponding to the daily dose of Levothyroxine her endocrinologist prescribed (112 ug). The patient was monitored at baseline, between each dose and up to 3 hours after the procedure was completed. There were no incidents such as urticaria, angioedema, or others. On the second day, the patient received a single-full dose of 112 ug on an empty stomach. The medication was successfully tolerated and she was discharged. Thereafter, she tolerates daily Levothyroxine.

WAO consensus on DEfinition of Food Allergy SEverity (DEFASE).

Background: While several scoring systems for the severity of anaphylactic reactions have been developed, there is a lack of consensus on definition and categorisation of severity of food allergy disease as a whole. Aim: To develop an international consensus on the severity of food allergy (DEfinition of Food Allergy Severity, DEFASE) scoring system, to be used globally. Methods Phase 1: We conducted a mixed-method systematic review (SR) of 11 databases for published and unpublished literature on severity of food allergy management and set up a panel of international experts. Phase 2: Based on our findings in Phase 1, we drafted statements for a two-round modified electronic Delphi (e-Delphi) survey. A purposefully selected multidisciplinary international expert panel on food allergy (n = 60) was identified and sent a structured questionnaire, including a set of statements on different domains of food allergy severity related to symptoms, health-related quality of life, and economic impact. Participants were asked to score their agreement on each statement on a 5-point Likert scale ranging from "strongly agree" to "strongly disagree". Median scores and percentage agreements were calculated. Consensus was defined a priori as being achieved if 70% or more of panel members rated a statement as "strongly agree" to "agree" after the second round. Based on feedback, 2 additional online voting rounds were conducted. Results: We received responses from 92% of Delphi panel members in round 1 and 85% in round 2. Consensus was achieved on the overall score and in all of the 5 specific key domains as essential components of the DEFASE score. Conclusions: The DEFASE score is the first comprehensive grading of food allergy severity that considers not only the severity of a single reaction, but the whole disease spectrum. An international consensus has been achieved regarding a scoring system for food allergy disease. It offers an evaluation grid, which may help to rate the severity of food allergy. Phase 3 will involve validating the scoring system in research settings, and implementing it in clinical practice.

Real-world data using mHealth apps in rhinitis, rhinosinusitis and their multimorbidities.

Digital health is an umbrella term which encompasses eHealth and benefits from areas such as advanced computer sciences. eHealth includes mHealth apps, which offer the potential to redesign aspects of healthcare delivery. The capacity of apps to collect large amounts of longitudinal, real-time, real-world data enables the progression of biomedical knowledge. Apps for rhinitis and rhinosinusitis were searched for in the Google Play and Apple App stores, via an automatic market research tool recently developed using JavaScript. Over 1500 apps for allergic rhinitis and rhinosinusitis were identified, some dealing with multimorbidity. However, only six apps for rhinitis (AirRater, AllergyMonitor, AllerSearch, Husteblume, MASK-air and Pollen App) and one for rhinosinusitis (Galenus Health) have so far published results in the scientific literature. These apps were reviewed for their validation, discovery of novel allergy phenotypes, optimisation of identifying the pollen season, novel approaches in diagnosis and management (pharmacotherapy and allergen immunotherapy) as well as adherence to treatment. Published evidence demonstrates the potential of mobile health apps to advance in the characterisation, diagnosis and management of rhinitis and rhinosinusitis patients.

Urinary leukotrienes in patients with nasal polyposis.

OBJECTIVES: To compare urinary leukotriene E4 (ULT) level in patients with nasal polyposis (NP) with and without aspirin intolerance and allergic rhinitis (AR), and correlate it with disease severity. STUDY DESIGN AND SETTING: Prospective study from November 2005 to November 2006. Patients with NP (n = 30) and AR (n = 35) were included. The concentration of ULT was measured in both groups. Oral provocation test with aspirin was performed to patients with NP. ULT level between both groups was compared and correlated with NP disease severity. RESULTS: ULT concentration was elevated on NP and AR. The patients with NP and aspirin intolerance (n = 4) presented higher levels of ULT compared to aspirin-tolerant patients. Leukotriene concentration was not correlated with NP severity. CONCLUSIONS: Patients with NP and aspirin intolerance have increased ULT excretion; thus their measurement can be used as an indicator of arachidonic acid metabolism alteration.

Tolerogenic dendritic cells derived from donors with natural rubber latex allergy modulate allergen-specific T-cell responses and IgE production.

Natural rubber latex (NRL; Hevea brasiliensis) allergy is an IgE-mediated reaction to latex proteins. When latex glove exposure is the main sensitizing agent, Hev b 5 is one of the major allergens. Dendritic cells (DC), the main antigen presenting cells, modulated with pharmacological agents can restore tolerance in several experimental models, including allergy. In the current study, we aimed to generate DC with tolerogenic properties from NRL-allergic patients and evaluate their ability to modulate allergen-specific T and B cell responses. Here we show that dexamethasone-treated DC (dxDC) differentiated into a subset of DC, characterized by low expression of MHC class II, CD40, CD80, CD86 and CD83 molecules. Compared with LPS-matured DC, dxDC secreted lower IL-12 and higher IL-10 after CD40L activation, and induced lower alloantigenic T cell proliferation. We also show that dxDC pulsed with the dominant Hev b 5 T-cell epitope peptide, Hev b 5(46-65), inhibited both proliferation of Hev b 5-specific T-cell lines and the production of Hev b 5-specific IgE. Additionally, dxDC induced a subpopulation of IL-10-producing regulatory T cells that suppressed proliferation of Hev b 5-primed T cells. In conclusion, dxDC generated from NRL-allergic patients can modulate allergen-specific T-cell responses and IgE production, supporting their potential use in allergen-specific immunotherapy.

[Association of dietary patterns and food allergy in infants during the first year of life]. / Asociación entre los patrones alimentarios durante el primer año de vida y alergia alimentaria en lactantes

INTRODUCTION: There is controversy about the effect of dietary patterns during the first year of life and the occurrence of food allergy. The objective of this study was to evaluate the association between family history of allergy, allergic manifestations and dietary patterns during the first year of life in infants with and without food allergy. POPULATION AND METHODS: We performed a descriptive cross-sectional study in children under 2 years of age (n= 99), sorted in two groups: allergic group (n= 50) and control group (n= 49), matched by socioeconomic status, age and gender. Food allergy was deifned by internationally approved clinical criteria, prick and patch tests, and response to diet. Information on diet, clinical data and history of allergy in the parents were collected. The sample size was estimated for logistic regression (Freeman), and Student X² and Mann-Withney tests were used. The study and consent forms were approved by the Ethics Committee of the Institute of Nutrition and Food Technology (Instituto de Nutrición y Tecnología de los Alimentos, INTA) and the Universidad de Chile. RESULTS: The allergic group showed a significantly higher prevalence (p <0.0001) of family history of allergy (84%) than the control group (16%). Diarrhea was the symptom most frequently reported by the mothers of allergic infants during the first year of life. Bottle feeding was introduced earlier in the allergic group than in the control group (3 versus 6 months [p < 0.03]); no differences regarding the start age for supplementary feeding was found. When performing logistic regression, only the family history of allergy was associated with a higher risk of food allergy (OR: 48.2; CI= 14.2-164; p < 0.001). CONCLUSIONS: The early introduction of milk formula could promote the occurrence of food allergy in infants frequently presenting family history of allergy.

[Allergic rhinitis update and its impact on asthma (ARIA 2008). Latin American perspective]. / Actualización de rinitis alérgica y su impacto en el asma (ARIA 2008). La perspectiva latinoamericana.

Rhinitis is the most frequent respiratory disease in most countries of the world. It is estimated that 600 million people suffer this condition. Allergic rhinitis is a public health problem at global level. Patients who suffer allergic rhinitis have from mild to annoying nasal symptoms which affect quality of life, cause sleep disorders, scholar and workplace absenteeism, and health expenditure. Rhinitis is frequently associated to co-morbidities such as sinusitis, otitis media, and especially asthma. Rhinitis is under-diagnosed and under-treated worldwide and also in Latin American countries. ARIA is the very first evidence-based guideline for the diagnosis and treatment of rhinitis with focus in its co-morbidities (2001), especially asthma published in 2001. In 2008 an update was published. ARIA recommends an integrative approach for management; including anti-histamines (second generation), intra-nasal corticosteroids, anti-leukotrienes and immunotherapy. It also provides a questionnaire to evaluate asthma and its severity in those patients suffering rhinitis. The prevalence of allergic rhinitis is quite high in Latin American countries and in recent years a great insight on the burden of this condition has been gained.

Asociación entre los patrones alimentarios durante el primer año de vida y alergia alimentaria en lactantes / Association of dietary patterns and food allergy in infants during the first year of life

Introducción. Existe controversia acerca del efecto del patrón alimentario durante el primer año de vida y el desarrollo de alergia alimentaria. El objetivo de este estudio fue evaluar la asociación entre antecedentes familiares de alergia, manifestaciones alérgicas y patrones alimentarios del primer año de vida en lactantes con alergia alimentaria y sin ella. Población y métodos. Se realizó un estudio descriptivo transversal en menores de 2 años (n= 99), distribuidos en dos grupos: alérgico (n= 50) y grupo control (n= 49), pareados por nivel socioeconómico, edad y género. Se definió alergia alimentaria según criterios clínicos internacionalmente aceptados, pruebas cutáneas y de parche, y respuesta a la dieta. Se recolectó información dietaria, clínica y de historia de alergia en los padres. Se calculó tamaño muestral para regresión logística (Freeman) y se utilizaron pruebas de Student, X² y Mann-Withney. El estudio y el consentimiento fueron aprobados por el Comité de Ética del INTA y de la Universidad de Chile. Resultados. El grupo alérgico mostró una prevalencia significativamente mayor (p <0,0001) de historia familiar de alergia (84%) que el grupo control (16%). La diarrea fue la sintomatología más frecuentemente comunicada por las madres de los niños alérgicos durante el primer año de vida. La lactancia artificial se introdujo más tempranamente en el grupo alérgico que en el grupo control 3 contra 6 meses (p <0,03); no hallamos diferencias con respecto a la edad de inicio de la alimentación complementaria. Al realizar la regresión logística, solo la historia familiar de alergia se asoció con un mayor riesgo de presentar alergia alimentaria (OR: 48,2; IC= 14,2-164; p <0,001). Conclusiones. La introducción precoz de formula láctea podría favorecer la presencia de alergia alimentaria en lactantes que presentan frecuentemente antecedentes familiares de alergia.
