Heterogeneity of the pharmacologic treatment of allergic rhinitis in Europe based on MIDAS and OTCims platforms.

BACKGROUND: The practice of allergology varies widely between countries, and the costs and sales for the treatment of rhinitis differ depending on practices and health systems. To understand these differences and their implications, the rhinitis market was studied in some of the EU countries. METHODS: We conducted a pharmaco-epidemiological database analysis to assess the medications that were being prescribed for allergic rhinitis in the years 2016, 2017 and 2018. We used the IQVIA platforms for prescribed medicines (MIDAS®- Meaningful Integration of Data, Analytics and Services) and for OTC medicines (OTC International Market Tracking-OTCims). We selected the five most important markets in the EU (France, Germany, Italy, Poland and Spain). RESULTS: Intranasal decongestants were excluded from the analyses because they are rarely prescribed for allergic rhinitis. For both Standard Units (SU) and costs, France is leading the other countries. In terms of SU, the four other countries are similar. For costs, Poland is lower than the three others. However, medication use differs largely. For 2018, in SU, intranasal corticosteroid is the first treatment in Poland (70.0%), France (51.3%), Spain (51.1%) and Germany (50.3%), whereas the Italian market is dominated by systemic antihistamines (41.4%) followed by intranasal corticosteroids (30.1%). Results of other years were similar. DISCUSSION: There are major differences between countries in terms of rhinoconjunctivitis medication usage.

Allergy/Immunology Trainee Experiences During the COVID-19 Pandemic: AAAAI Work Group Report of the Fellows-in-Training Committee.

As a result of the coronavirus disease 2019 (COVID-19) global pandemic, medical trainees have faced unique challenges and uncertainties. To capture the experiences of allergy and immunology fellows throughout the United States and Canada during this time, a 17-item electronic questionnaire was distributed to 380 fellow-in-training (FIT) members of the American Academy of Allergy, Asthma, and Immunology enrolled in US and Canadian allergy/immunology fellowship programs. Voluntary and anonymous responses were collected from April 15 to May 15, 2020. In addition to summary statistics, categorical data were compared using χ2 tests (Fisher's exact). Responses were obtained from FITs across all years of training and primary specialties (Internal Medicine, Pediatrics, and Medicine-Pediatrics) with a response rate of 32.6% (124 of 380). Reassignment to COVID-19 clinical responsibilities was reported by 12% (15 of 124) of FITs, with the largest proportion in the US northeast region. A majority of FITs used telehealth (95%) and virtual learning (82%) during the pandemic. Overall, 21% (25 of 120) of FITs expressed concern about potentially lacking clinical experience for independently practicing allergy and immunology. However, FITs using telehealth reported lower concern compared with those who did not (18.4% [21 of 114] vs 66.7% [4 of 6]; P = .01). The survey shows that allergy and immunology trainee experiences have varied considerably since the COVID-19 outbreak. Notably, the adoption of telehealth and virtual learning was commonly reported, and optimization of these virtual experiences will be helpful. Even outside of pandemics, training on the use of telemedicine may be a sound strategy in preparation for future health care delivery and unexpected events.

Authorship and citation gender trends in immunology and microbiology.

Immunology and microbiology research are essential for human and animal health. Unlike many other health fields, they do not usually centre around the curing or helping individual patients but focus on the microscopic scale instead. These fields are interesting from a gender perspective because two theories seeking to explain gender differences in career choices in the USA (people/things and communal/agentic goals) might produce conflicting expectations about their gender balances. This article assesses the gender shares of journal articles and gendered citation rates of five subfields of the Scopus Immunology and Microbiology broad category 1996-2014/18, for research with solely US author affiliations. Only Applied Microbiology and Biotechnology (38% female) had not reached gender parity in publishing by 2018. There was a female first author citation advantage in Parasitology but a disadvantage in Immunology. Immunology, Parasitology and Virology, had female last author citation disadvantages, but all gender effects were much smaller (<5%) than that of an extra author (10%-56%). Citation differences cannot therefore account for the current underrepresentation of women in senior roles.

Four seasons of Czech asthma study: asthma characteristics and management reality in the Czech Republic.

Objective: To describe the characteristics and management of asthma in clinical practice in the Czech Republic in the context of international guidelines and clinical realities.Methods: Data were collected over four seasons from summer 2016 to spring 2017 and are mostly presented using descriptive statistics.Results: We obtained valid data for 4557 adult patients with asthma, including detailed phenotyping (71% eosinophilic allergic, 10% eosinophilic non-allergic, 19% non-eosinophilic non-allergic asthma) from 58 allergologists and 56 pulmonologists. The average time to diagnosis was 3 years. In more than half of the subjects, bronchodilator testing (BDT) results were available at primary diagnosis. More than 10% of physicians did not test for mold allergy. Occupational asthma was diagnosed in 0.7% of subjects. According to the attending physician, 68% of patients had well-controlled and 10% had uncontrolled asthma. Ninety-four percent of patients were on preventive treatment, with 91% using an inhaled corticosteroids (ICS) at an average dose of 705 µg/day budesonide equivalent. Approximately 75% of patients were on an ICS/LABA, with 91% using fixed combinations. Among patients using ICS/formoterol, a maintenance and reliever therapy regime was prescribed in 67%.Conclusions: The quality of asthma management in the Czech Republic is comparable to that of other developed countries and better in some respects (frequent BDT, phenotyping, and use of preventive treatment). Nevertheless, there is unnecessary delay in diagnosis and lack of research on possible environmental causes (workplace, molds). Pharmacotherapy shows good adherence to guidelines. Although 10% of patients show poor control, there is concurrently a trend for overtreatment.

Does Provider Specialty Matter?

OBJECTIVES: Multiple practice guidelines discourage indiscriminate use of broad panels of allergen-specific IgE (sIgE) tests due to increased risk of false positives and misinterpretation of results. We provide an analytical framework to identify specialty-specific differences in ordering patterns and effectiveness, which can be used to improve test utilization. METHODS: Test results from a tertiary pediatric hospital were analyzed by ordering specialty to evaluate size of allergen workups. Positivity rates were analyzed to determine effectiveness in selecting tests with high positive pretest probabilities. Laboratory test menu components were also evaluated. RESULTS: Our findings demonstrate 29% of sIgE tests are ordered as part of broad workups (>20 sIgE tests/date of service) contrary to the recommended testing approach. Detailed descriptions of ordering patterns and positivity rates are provided. CONCLUSIONS: This study provides a framework for using a cross-sectional analytical approach to assess test utilization patterns and evaluate components of laboratory testing menus.

Type B adverse drug reactions reported by an immunoallergology department

Objective: Characterization of the adverse drug reactions (ADR) reported by the immunoallergology department (IAD), Centro Hospitalar de São João (Porto), to the Northern Pharmacovigilance Centre (NPC). Methods: An observational, descriptive and retrospective study was conducted, based in a spontaneous report system. Participants were all the patients from the IAD, with suspected ADR, reported to NPC by specialists after the study was completed. Results: Studied population had a median age of 41 years, with the predominance of the female gender (73.2%). Allergic rhinitis and asthma were the most frequent comorbidities. All studied ADR were type B, 89.6% were serious, 86.4% unexpected and 2.6% associated with drugs that presented less than 2 years in the market. The most represented drug classes were the non-steroidal anti-inflammatory drugs (NSAIDs) (52.6%) and antibiotics (25.2%). Skin symptoms represented 61.2% of the reported complaints. About 52.9% of these ADR occurred in less than one hour after intake. The most frequent ADR treatment at the time of the reaction was drug interruption (86.2%), followed by the prescription of anti-histamines (42.2%). Conclusions: Reported ADR to NPC by the Drug Alert Unitwere mainly serious, unexpected, associated with NSAIDs and antibiotics and related with marketing authorization medicines older than two years. These results could be very useful to develop strategiesto prevent the clinical and economic consequences of ADR (AU)

Diagnosis and treatment of allergic diseases in Zhejiang Province: a cross-sectional survey.

BACKGROUND: The specialty of allergy developed quickly in western countries because of the rapid increase of allergic diseases, whereas it developed relatively slowly in China. The prevalence of allergen sensitization and allergic diseases in Zhejiang Province of China is high and improving the medical services for these diseases is critically needed. OBJECTIVE: To investigate the working status of the diagnosis and treatment of allergic diseases, including doctor resources, diagnostic methods, and allergen-specific immunotherapy in patients of Zhejiang Province, and to provide instructions for the strategic development of subspecialties of allergic diseases. METHODS: First we defined the doctors who treat allergic diseases, and designed a comprehensive questionnaire to collect personal and hospital information for these doctors. The questionnaires were distributed to hospitals with different ranks and from different areas in the province. The general condition of doctor's resources, carryout of diagnostic methods, and allergen-specific immunotherapy were described and variations in the different specialties, hospitals, and areas were further analyzed. RESULTS: Doctors in their thirties with bachelor's degrees were the mainstream for diagnosing and treating allergic diseases. The main specialties of the doctor resources were the specialties of Ear, Nose and Throat (ENT), Respirology, Pediatrics, and Dermatology. The Pediatrics specialty had a more reasonable infrastructure of doctor resources with more young doctors working in this subspecialty. The development of allergy subspecialty varied within hospitals at different levels or from different areas. The carryout of the skin prick test (SPT), serum specific IgE (ssIgE), and subcutaneous immunotherapy (SCIT) was best performed in provincial hospitals, while sublingual immunotherapy (SLIT) was prescribed most commonly in municipal hospitals. The performance of SPT and ssIgE in Hangzhou, Jiaxing, and Wenzhou areas was much better than that in other places. The performance of SCIT and SLIT was best in Wenzhou. CONCLUSIONS: Our survey revealed a very initial and unbalanced development for the allergy subspecialty in Zhejiang Province. Doctor resources for allergic diseases were mainly from the specialties of ENT, Respirology, and Pediatrics, and the performance of diagnosis and treatment was mainly focused on provincial and municipal hospitals. Continuous education of allergies could be extended to primary healthcare centers and more efforts should be directed to those areas with poor medical resources.

Doctors’ awareness concerning primary immunodeficiencies in Brazil

BACKGROUND: PIDs are a heterogeneous group of genetic illnesses, and delay in their diagnosis is thought to be caused by a lack of awareness among physicians concerning PIDs. The latter is what we aimed to evaluate in Brazil. METHODS: Physicians working at general hospitals all over the country were asked to complete a 14-item questionnaire. One of the questions described 25 clinical situations that could be associated with PIDs and a score was created based on percentages of appropriate answers. RESULTS: A total of 4026 physicians participated in the study: 1628 paediatricians (40.4%), 1436 clinicians (35.7%), and 962 surgeons (23.9%). About 67% of the physicians had learned about PIDs in medical school or residency training, 84.6% evaluated patients who frequently took antibiotics, but only 40.3% of them participated in the immunological evaluation of these patients. Seventy-seven percent of the participating physicians were not familiar with the warning signs for PIDs. The mean score of correct answers for the 25 clinical situations was 48.08% (±16.06). Only 18.3% of the paediatricians, 7.4% of the clinicians, and 5.8% of the surgeons answered at least 2/3 of these situations appropriately. CONCLUSIONS: There is a lack of medical awareness concerning PIDs, even among paediatricians, who have been targeted with PID educational programmes in recent years in Brazil. An increase in awareness with regard to these disorders within the medical community is an important step towards improving recognition and treatment of PIDs

Allergist-reported trends in the practice of food allergen oral immunotherapy.

Food allergen oral immunotherapy (OIT) is an experimental, immune-modifying therapy that may induce clinical desensitization in some patients. OIT is still in early phase clinical research, but some providers may offer OIT as a clinical service. To understand the current practices of allergists who perform OIT, an online survey was sent by e-mail to members of the American Academy of Allergy Asthma & Immunology. Among 442 respondents, 61 reported participating in using OIT (13.8%), including 28 in nonacademic settings. Informed consent for OIT was obtained by 91.3%, institutional review board approval by 47.7% and Investigational New Drug approval by 38.1%. Compared with nonacademic participants, more academic participants used peanut OIT, obtained institutional review board and Investigational New Drug (P < .0001 respectively), and challenged patients before entry (P = .008). More nonacademic providers billed the patient or insurance for reimbursement (P < .0001). Low reported regard for the importance for US Food and Drug Administration approval or a standardized product (increased odds), and a high regard for better safety data (decreased odds) were associated with considering offering OIT as a service. Significant differences exist with OITs that occur in academic versus nonacademic settings. Further assessment is needed regarding the different motivations and practice styles among providers who offer OIT and those who are considering doing so.

Outcomes of allergy/immunology follow-up after an emergency department evaluation for anaphylaxis.

BACKGROUND: Anaphylaxis guidelines currently recommend referring patients with anaphylaxis seen in the emergency department (ED) to an allergist for follow up. OBJECTIVE: The objective of our study was to evaluate outcomes of allergy/immunology follow-up after an ED visit for anaphylaxis. METHODS: A retrospective health records review was conducted from April 2008 to August 2012. Charts were reviewed independently by 2 allergists to determine outcomes. Descriptive statistics with corresponding 95% CIs were calculated. RESULTS: Among 573 patients seen in the ED who met anaphylaxis diagnostic criteria, 217 (38%) had a documented allergy/immunology follow-up. After allergy/immunology evaluation, 16 patients (7% [95% CI, 5%-12%]) had anaphylaxis ruled out. Among those with an unknown ED trigger (n = 74), 24 (32% [95% CI, 23%-44%]) had a trigger identified; and, among those who had a specific suspected ED trigger (n = 143), 9 (6% [95% CI, 3%-12%]) had a trigger identified in a category other than the one suspected in the ED, and 28 (20% [95% CI, 14%-27%]) had an unknown trigger. Thus, there were a total of 77 patients (35% [95% CI, 29%-42%]) who had an alteration in the diagnosis of anaphylaxis or trigger after allergy/immunology evaluation. Four patients (2% [95% CI, 0.7%-4.6%]) were diagnosed with a mast cell activation disorder, and 13 patients (6% [95% CI, 4%-10%]) underwent immunotherapy or desensitization. CONCLUSION: Overall, 35% of the patients with suspected anaphylaxis in the ED had an alteration in the diagnosis or suspected trigger after allergy/immunology evaluation. These results underscore the importance of allergy/immunology follow-up after an ED visit for anaphylaxis.

La alergología en el sistema sanitario público de la Comunidad de Madrid: situación actual y oportunidades en el sistema sanitario público del siglo XXI / Allergology in the public health service of the Community of Madrid: current situation and opportunities in the XXI century public health system

La alta prevalencia de las enfermedades alérgicas y una mayor complejidad diagnóstica y terapéutica, exigen un alergólogo altamente capacitado profesionalmente y organizaciones sanitarias conocedoras de los recursos humanos y estructurales disponibles. En España faltan datos actualizados en alergología e indicadores de actividad que reflejen esta complejidad. Este trabajo analiza la situación, detecta necesidades y plantea soluciones de mejora para la alergología en la Comunidad de Madrid. Los 24 jefes de servicio de Alergología de los hospitales públicos madrileños con asistencia alergológica, completaron voluntariamente la encuesta diseñada específicamente para este trabajo, con datos de actividad asistencial (2010), docencia e investigación (2009-2010). Se realizó un análisis DAFO y se diseñaron líneas estratégicas y propuestas de mejora orientadas a adoptar las soluciones más idóneas. Un total de 117 alergólogos (41% doctores) en el sistema público de salud (4,6 profesionales/centro; ≤ 3 en 10 hospitales), realizaban consulta externa (4000 primeras consultas/ hospital/año, 36% de alta resolución; 6200 visitas sucesivas/ hospital/año). Se ejecutaban procedimientos básicos diagnósticos y terapéuticos, incluyendo pruebas complejas propias de hospital de día, mayoritariamente no reconocidas en los indicadores de actividad. Dos hospitales tenían hospitalización propia y 10 disponían de acreditación docente (2,78 MIR/año). Bianualmente, un servicio participaba en 4 proyectos de investigación, 2 ensayos clínicos, 16 publicaciones y 17 comunicaciones a congresos, con notables diferencias entre hospitales. Madrid cuenta con alergólogos bien preparados y una organización asistencial alergológica adecuada aunque posiblemente insuficiente. Nuevas herramientas de registro de actividad y el incremento de la cooperación corporativa, aprovechando nuevas tecnologías y la proximidad geográfica, mejorarían la calidad y la eficiencia (AU)

The high prevalence of allergic diseases and the use of more complex diagnostic techniques and therapeutic options require allergists to be highly trained professionals and healthcare organizations to be knowledgeable about available structural and human resources. Updated information is lacking in Spain, and current activity indicators do not reflect complexity. The present article analyzes the situation of allergology in Madrid and proposes improvements where necessary. The heads of the allergy departments of public hospitals in Madrid voluntarily completed a purpose-designed survey. Data on care activity (2010) and on teaching and research activity (2009-2010) were provided. A SWOT analysis was performed, and strategic lines and proposals for improvement were designed. One hundred and seventeen allergists (41% with a PhD) worked in 24 hospitals with an allergology department (4.6 physicians/center; ≤3 in 10 hospitals). All the institutions had an outpatient clinic (4,000 first consultations/hospital/year, 36% high-resolution rate; 6200 successive visits/hospital/year) performing complex diagnostic and therapeutic procedures, most of which were not taken into account by activity indicators. Two hospitals had their own hospitalization facilities and 10 were accredited teaching hospitals (2.78 medical residents/ year). The survey revealed that, twice yearly, a typical allergology service participated in 4 research projects, 2 clinical trials, 16 publications and 17 communications at scientific meetings, with notable differences between hospitals. Allergists in Madrid are well prepared. The allergology care structure is adequate, although possibly insufficient. Quality and efficiency can be improved with new tools for recording activity and by increasing coordination and taking advantage of new technologies and geographical proximity (AU)

The impact of double-blind placebo-controlled food challenge (DBPCFC) on the socioeconomic cost of food allergy in Europe

Background: Double-blind placebo controlled food challenge (DBPCFC) is the gold standard diagnostic test in food allergy because it minimizes diagnostic bias. Objective: To investigate the potential effect of diagnosis on the socioeconomic costs of food allergy. Methods: A prospective longitudinal cost analysis study was conducted in Spain and Poland within the EuroPrevall project. Food-allergic patients were enrolled into the study and in all cases diagnosis was confirmed through a standardized DBPCFC. Data were collected through a self-administered survey on all aspects of health and social care resource use, costs of living, and costs of leisure activities. Costs were measured before and 6 months after the DBPCFC and reported in international dollars with 2007 as the benchmark year. Results: Forty-two patients were enrolled. Twenty-one patients had a negative DBPCFC and the suspected food was reintroduced into their diet. Comparing total direct costs before and after the DBPCFC, the reactive group spent a significantly higher amount (median increase of $813.1 over baseline), while the tolerant group’s spending decreased by a median of $87.3 (P=.031). The amount of money spent on food 6 months after diagnosis was also significantly higher in the reactive group (P=.040). Finally, a larger, but not statistically significant, decrease in total indirect costs was observed in the tolerant group compared with the reactive group ($538.3 vs $32.3). Conclusion: DBPCFC has an impact on indirect and direct costs of living. The main contribution to this increase was money spent on food (AU)

Introducción: La provocación oral doble ciego controlada con placebo (PODCCP) es prueba diagnóstica "gold standard" en alergia a alimentos. Objetivo: El objetivo de este estudio es investigar el efecto del diagnóstico en los costes socioeconómicos de la alergia a alimentos (AA). Métodos: Estudio prospectivo longitudinal de análisis de costes llevado a cabo en España y Polonia en el contexto de proyecto EuroPrevall. Se seleccionaron pacientes con AA y en todos los casos el diagnóstico fue estandarizado a través de una PODCCP estandarizada. Se utilizaron cuestionarios autoadministrados para recoger datos del uso de recursos sociosanitarios, coste de vida y coste de actividades de ocio. Los costes se midieron en dos puntos, antes y 6 meses después de PODCCP, expresados en dólares internacionales (nivel de costes 2007). Resultados: Se incluyeron 42 pacientes. 21 pacientes tuvieron una PODCCP negativa y se reintrodujo el alimento. Comparando los costes directos antes y después de PODCCP, el gasto en el grupo de pacientes reactivos fue significativamente mayor (mediana de incremento $813,1 a los 6 meses), mientras que en el grupo de pacientes tolerantes disminuyó una mediana de $87,3 (p=0,031). Los pacientes con una provocación positiva gastaron también más dinero en comida a los 6 meses del diagnóstico (p=0,040). Por último, los costes indirectos disminuyeron, aunque de forma no estadísticamente significativa, en el grupo de pacientes tolerantes comparado con los reactivos ($ 538,3 versus $32,3). Conclusión: La PODCCP tiene un impacto en los costes directos e indirectos, en su mayor parte debido al dinero gastado en comida (AU)

SLIT: indications, follow-up, and management

La inmunoterapia específica sublingual (SLIT) ha demostrado ser un tratamiento seguro y eficaz para la alergia respiratoria. Sin embargo, aspectos como la selección del paciente, el empleo de dosis óptimas, sus efectos en el asma y a largo plazo, o el manejo de las reacciones adversas necesitan una mayor investigación. Además, la gran heterogeneidad de estudios realizados con SLIT y la aplicación de los mismos criterios que los que se aplican a la inmunoterapia subcutánea dificultan la obtención de conclusiones precisas y útiles al clínico que prescribe este tratamiento. Por ello, el grupo Quasar (QUality in the Administration of SLIT in Allergic Rhinitis), grupo de alergólogos con amplia experiencia clínica con SLIT, se propuso recoger el estado de la investigación actual y los datos reales disponibles con SLIT. Para ello, se establecieron grupos de trabajo en tres categorías distintas: selección del paciente candidato a recibir SLIT, eficacia del tratamiento y reacciones adversas. Se realizó una búsqueda de artículos representativos para cada tema, localizándose inicialmente en PubMed 850, de los que se seleccionaron y analizaron 314 para extraer la evidencia disponible con SLIT, incorporando finalmente 266 al documento. Se realizó la gradación de la evidencia para cada pregunta clínica según la clasificación de Oxford. El texto resultante fue evaluado hasta en tres ocasiones por todos los miembros del grupo hasta consensuar el documento final que revisa el cuerpo de la evidencia existente hasta el momento sobre SLIT, particularmente con pólenes, sobre los que existe un mayor número de artículos, y, para aquellos aspectos en los que se ha demostrado evidencia insuficiente, propone una alternativa consensuada entre los miembros del grupo Quasar. Finalmente, se proponen algoritmos de selección del paciente candidato para SLIT y de manejo de reacciones adversas (AU)

Specific sublingual immunotherapy (SLIT) has been proved to be a safe and effective approach in respiratory allergy. However, further research is required on aspects such as patient selection, use of optimal dosing, effects on asthma, long-term effects, and management of adverse reactions. In addition, the widely heterogeneous nature of studies on SLIT performed to date and the application of the criteria for subcutaneous immunotherapy make it difficult for the prescribing clinician to draw accurate and useful conclusions. Therefore, the QUASAR Group (QUality in the Administration of SLIT in Allergic Rhinitis), which comprises allergologists with broad clinical experience in SLIT, investigated the latest research findings and available data on this approach. Working parties were formed in 3 different categories: selection of candidates for SLIT, treatment efficacy, and adverse reactions. We performed a PubMed search for articles that were representative of each category and found 850. From these, we finally selected 266 articles, which were reviewed to retrieve data on SLIT. Evidence for each clinical question was graded according to the Oxford classification. The resulting text was evaluated on 3 occasions by all the members of the group until the final version was agreed upon. In this version, we review available evidence on SLIT, particularly with pollens, which is the subject of most articles. In areas where evidence is insufficient, an alternative agreed upon by the members of the QUASAR group is presented. Finally, we propose algorithms for selecting candidates for SLIT and for management of adverse events (AU)
