How an online survey on the treatment of allergic rhinitis and its impact on asthma (ARIA) detected specialty-specific knowledge-gaps

Background To enhance the dissemination of the ARIA document (Allergic rhinitis (AR) and its impact on asthma) in Mexico, a Working Group composed of 35 specialists of 8 professional medical societies developed a transculturized ARIA México 2014 guideline. The ARIA guidelines use the GRADE system, which builds recommendations and suggestions around clinical questions (CQ).Methods As part of the dissemination strategy and to detect the physicians’ view and knowledge-gaps concerning the treatment of AR an online survey was sent out to members of participating societies containing the CQ of ARIA México. Replies were analyzed per specialty against the ARIA México 2014 experts’ recommendations/suggestions; differences between specialties were analyzed with Pearson’s Chi-squares.Results 807 surveys were returned, 657 completed (81%). We analyze replies from 158 alergists, 188 ENTs, 64 pulmonologists, 220 pediatricians and 177 GPs/family doctors. More than half of the surveyed physicians of all specialties would give an allergen reduced diet to pregnant/lactating women and avoid pets at home, which is against ARIA experts’ suggestions. ARIA experts suggest intranasal antihistamines can be part of the AR treatment: 46-63% of the ENTs, pulmonologists and pediatricians disagree; and experts prefer oral H1-antihistamines over leukotriene receptor antagonists (LTRA) for the treatment of AR: 52-36% of the pulmonologists, pediatricians and GPs prefer LTRAs. Concerning glucocorticosteroids (GCS): GPs are more reluctant to use intranasal GCS (p < 0.001) and 47% prefers oral H1-antihistamines. As for the treatment of recalcitrant AR ARIA experts suggest the use of oral, but not intramuscular, GCS: a quarter of pulmonologists, pediatricians and GPs considers they should not be used. Contrarily, 40% of ENTs favors intramuscular GCS. In patients with AR and comorbid asthma several physicians of all specialties –except pulmonologists- erroneously considers antihistamines, intranasal GCS and LTRAs useful for the treatment of asthma, while first-line recommended asthma treatment is inhaled GCS.Conclusion On certain issues in the treatment of AR the physicians’ opinion diverges from the recommendations/suggestions of ARIA experts. Moreover, physicians’ opinions depend on their specialty. As such, an online survey can help to detect knowledge-gaps and guide the development of more focused and specialty-specific postgraduate learning tools.

Compromising between European and US allergen immunotherapy schools: Discussions from GUIMIT, the Mexican immunotherapy guidelines

Background: Allergen immunotherapy (AIT) has a longstanding history and still remains the only disease-changing treatment for allergic rhinitis and asthma. Over the years 2 different schools have developed their strategies: the United States (US) and the European. Allergen extracts available in these regions are adapted to local practice. In other parts of the world, extracts from both regions and local ones are commercialized, as in Mexico. Here, local experts developed a national AIT guideline (GUIMIT 2019) searching for compromises between both schools. Methods: Using ADAPTE methodology for transculturizing guidelines and AGREE-II for evaluating guideline quality, GUIMIT selected 3 high-quality Main Reference Guidelines (MRGs): the European Academy of Allergy, Asthma and Immunology (EAACI) guideines, the S2k guideline of various German-speaking medical societies (2014), and the US Practice Parameters on Allergen Immunotherapy 2011. We formulated clinical questions and based responses on the fused evidence available in the MRGs, combined with local possibilities, patient's preference, and costs. We came across several issues on which the MRGs disagreed. These are presented here along with arguments of GUIMIT members to resolve them. GUIMIT (for a complete English version, see Supplementary data) concluded the following: Results: Related to the diagnosis of IgE-mediated respiratory allergy, apart from skin prick testing complementary tests (challenges, in vitro testing and molecular such as species-specific allergens) might be useful in selected cases to inform AIT composition. AIT is indicated in allergic rhinitis and suggested in allergic asthma (once controlled) and IgE-mediated atopic dermatitis. Concerning the correct subcutaneous AIT dose for compounding vials according to the US school: dosing tables and formula are given; up to 4 non-related allergens can be mixed, refraining from mixing high with low protease extracts. When using European extracts: the manufacturer's indications should be followed; in multi-allergic patients 2 simultaneous injections can be given (100% consensus); mixing is discouraged. In Mexico only allergoid tablets are available; based on doses used in all sublingual immunotherapy (SLIT) publications referenced in MRGs, GUIMIT suggests a probable effective dose related to subcutaneous immunotherapy (SCIT) might be: 50–200% of the monthly SCIT dose given daily, maximum mixing 4 allergens. Also, a table with practical suggestions on non-evidence-existing issues, developed with a simplified Delphi method, is added. Finally, dissemination and implementation of guidelines is briefly discussed, explaining how we used online tools for this in Mexico. Conclusions: Countries where European and American AIT extracts are available should adjust AIT according to which school is followed

Allergen sensitization linked to climate and age, not to intermittent-persistent rhinitis in a cross-sectional cohort study in the (sub)tropics

Background: Allergen exposure leads to allergen sensitization in susceptible individuals and this might influence allergic rhinitis (AR) phenotype expression. We investigated whether sensitization patterns vary in a country with subtropical and tropical regions and if sensitization patterns relate to AR phenotypes or age. Methods: In a national, cross-sectional study AR patients (2-70 y) seen by allergists underwent blinded skin prick testing with a panel of 18 allergens and completed a validated questionnaire on AR phenotypes. Results: 628 patients were recruited. The major sensitizing allergen was house dust mite (HDM) (56%), followed by Bermuda grass (26%), ash (24%), oak (23%) and mesquite (21%) pollen, cat (22%) and cockroach (21%). Patients living in the tropical region were almost exclusively sensitized to HDM (87%). In the central agricultural zones sensitization is primarily to grass and tree pollen. Nationwide, most study subjects had perennial (82.2%), intermittent (56.5%) and moderate-severe (84.7%) AR. Sensitization was not related to the intermittent-persistent AR classification or to AR severity; seasonal AR was associated with tree (p < 0.05) and grass pollen sensitization (p < 0.01). HDM sensitization was more frequent in children (0-11 y) and adolescents (12-17 y) (subtropical region: p < 0.0005; tropical region p < 0.05), but pollen sensitization becomes more important in the adult patients visiting allergists (Adults vs children + adolescents for tree pollen: p < 0.0001, weeds: p < 0.0005). Conclusions: In a country with (sub)tropical climate zones SPT sensitization patterns varied according to climatological zones; they were different from those found in Europe, HDM sensitization far outweighing pollen allergies and Bermuda grass and Ash pollen being the main grass and tree allergens, respectively. Pollen sensitization was related to SAR, but no relation between sensitization and intermittent-persistent AR or AR severity could be detected. Sensitization patterns vary with age (child HDM, adult pollen). Clinical implications of our findings are dual: only a few allergens –some region specific- cover the majority of sensitizations in (sub)tropical climate zones. This is of major importance for allergen manufacturers and immunotherapy planning. Secondly, patient selection in clinical trials should be based on the intermittent-persistent and severity classifications, rather than on the seasonal-perennial AR subtypes, especially when conducted in (sub)tropical countries

Guía Mexicana para el Diagnóstico y el Tratamiento de la Urticaria

La urticaria es una enfermedad que padece una quinta parte de la población en algún momento de su vida. Las guías inter- nacionales recientes han propuesto unos cambios de fondo en su diagnóstico y tratamiento, por lo que había la necesidad de crear una guía nacional y multidisciplinaria, con base amplia en los gremios de especialistas y médicos de primer contacto en México. ABSTRACT Urticaria is a disease that a fifth of the population shall suffer once in a lifetime. Recent clinical guidelines have proposed some fundamental changes in the diagnosis and treatment of urticaria, making the development of a national, multidisciplinary guideline, with wide acceptability among different professional groups –both specialists and primary health care workers–, necessary in Mexico

Validation of a Diagnostic Questionnaire of Allergic Rhinitis in Children and Adults for Epidemiological Studies

Background: Allergic rhinitis is the most frequent allergic disease, characterized by nasal symptoms consisting of rhinorrhea, nasal block-age and sneezing triggered by and IgE mediated reaction to allergens. Objective: To validate a questionnaire for the clinical diagnosis of allergic rhinitis. Material and method: A test of a test in which a questionnaire for the clinical diagnosis of allergic rhinitis was developed and validated it in 300 subjects (150 children, 150 adults, of both genders, 2-70 years), in allergy specialized centers, between November 2012 and February 2014. Half of the subjects had allergist-diagnosed allergic rhinitis, the other half served as a control group. In patients below 12 years of age the questionnaire was applied to the parents. All questionnaires were applied in duplicate within a time-span of several weeks to validate the intra-subject consistency. Results: The tests applied to the answers of the questionnaire demonstrated an acceptable concordance in the Test-Retest for both, adults and children. Likewise, we found a very high inter-rater reliability: the agreement between 2 physicians being almost perfect. The test used for validation of the criteria in the adult questionnaire obtained 91% sensitivity, 89% speci city, PPV 89% and NPV 92% and in the children’s questionnaire 92% sensitivity and 93% speci city, PPV 93% and NPV 92% and the criteria for content validity and expression were properly met. The homogeneity test reached 0.7 (Alpha Cronbach). Conclusion: The questionnaire for allergic rhinitis in children and adults reached a highly acceptable inter-rater reliability, with high sensitivity and speci city in the validation of the criteria and an acceptable grade in the homogeneity test.

Prevalence of asthma and its symptoms in schoolchildren from Cuernavaca, Morelos, Mexico

Background: Asthma is a chronic disease that has increased over the past 2 decades. Objective: To determine the prevalence of asthma and its symptoms in the city of Cuernavaca, Morelos, Mexico. Methods: A descriptive study of prevalence in public schools of the city of Cuernavaca, Morelos, at the preschool, elementary, and high school levels using the “Asthma diagnosis for epidemiological studies questionnaire.” Results: 7947 surveys were obtained from students ages 3 to 15 years, funding a prevalence of asthma of 11.9%, 49% in boys and 51% in girls. As for the symptoms of asthma, the highest prevalence was cough that increases with cold weather (63%), however, in asthma patients this symptom only occurred in 17%; chest tightness had the lowest prevalence of symptoms (10%); however, in asthma patients it was 49%. Conclusions: The asthma diagnosis for epidemiological studies questionnaire found an average asthma prevalence of 11.9% in preschool, elementary, and high school students, slightly below that diagnosed in other cities in central Mexico. The prevalence of asthma symptoms was higher than the diagnosis of asthma

Prevalence of allergic rhinitis and its symptoms in the school children population of Cuernavaca, Morelos, Mexico

Background: Studies on allergic rhinitis prevalence have found significant variations in their results, even in closely-living populations. Objective: To determine and compare the prevalence of allergic rhinitis and its symptoms in schoolchildren from Cuernavaca, Morelos, Mexico. Methods: Cross-sectional, descriptive study on the prevalence of allergic rhinitis diagnosis and symptoms, where the “Diagnostic questionnaire for epidemiological studies” was used between June and December 2015 in pre-school and primary and secondary school population, after authorization was granted by parents and school authorities. Results: In 7866 surveys in a population aged between 3 and 15 years, 939 cases of allergic rhinitis (11.94%) were identified, with 53% belonging to the female gender. The symptom with the highest prevalence was cold-induced nasal congestion (56.8%), followed by rhinitis accompanied by ocular symptoms (35.8%) and recurrent flu-like symptoms (20), which was the most common symptom in allergic rhinitis (100%). Conclusions: A significant variation was observed in the prevalence of symptoms, notably higher than that of questionnaire-obtained allergic rhinitis diagnosis (11.94%), which suggests that the independent prevalence of symptoms is not a good parameter to detect the prevalence of allergic rhinitis
