- Sensitization to cat allergen and its association with respiratory allergies: cross-sectional study(2017) GALVAO, Clovis Eduardo Santos; GRAUDENZ, Gustavo Silveira; KALIL, Jorge; CASTRO, Fabio Fernandes MoratoCats are a significant source of allergens that contribute towards worsening of allergic diseases. The aim of this study was to investigate the association between sensitization to cat allergens and allergic respiratory diseases. This was an observational retrospective study based on the skin prick tests results of patients at a tertiary-level hospital in Sao Paulo. A total of 1,985 test results were assessed. The prevalence of sensitization to cat allergen was 20% (399 patients). Our data indicated that in this population of atopic patients, a positive skin prick test result for cat allergen was not associated significantly with a diagnosis of respiratory allergy.
- The international survey on the management of allergic rhinitis by physicians and patients (ISMAR)(2015) BAENA-CAGNANI, Carlos E.; CANONICA, Giorgio W.; HELAL, Mohamed Zaky; GOMEZ, Rene Maximiliano; COMPALATI, Enrico; ZERNOTTI, Mario E.; SANCHEZ-BORGES, Mario; CASTRO, Fabio F. Morato; AGUTTES, Margarita Murrieta; LOPEZ-GARCIA, Aida; TADROS, Faheem A.Epidemiologic studies suggest that the prevalence of allergic rhinitis (AR) is rising worldwide. Several reports, in fact, indicate increasing trends in the prevalence of AR especially in developing countries, likely related to the environment and climate changes and the adoption of an urbanized Western lifestyle. The primary objective of the present study was to collect information about management in real-life settings, including a characterization of typical patients' profile referring to physicians, the disease features, the common approaches to diagnostic assessments and therapeutic decisions. This was an international, multicenter, cross-sectional study conducted in adults or children (>= 6 years) suffering from rhinitis confirmed by physician's diagnosis for at least one year. The 234 physicians who participated in the study included a total of 2778 patients in Egypt, Mexico, Brazil, Colombia, Guatemala, Iran, Venezuela, Argentina, Israel, Kuwait and United Arab Emirates. It was found that clinical history was the selected tool to diagnose and categorize AR patients (97.1%), with less than half of patients undergoing allergy testing, may be explaining the scarce use of immunotherapy on management of disease. Out of 2776 patients, 93.4% had somehow received a recommendation to avoid allergens and irritant agent exposure. Notably, 91.4% were receiving at least one treatment at the time of the survey, mostly oral antihistamines (79.7%) and intranasal corticosteroids (66.3%). Oral antihistamines, intranasal steroids and decongestants were considered both safe and effective by patients and physicians, preferring oral and nasal route of administration. The ISMAR registry was designed according to the most accepted epidemiological recommendations, and provides interesting information regarding the management of rhinitis from a patient and physician points of view, with many similarities between the participating countries. Further efforts are required to better manage AR and its comorbidities.
bookPart Abordagem clínica do paciente com doenças imunoalérgicas(2022) GALVãO, Clóvis Eduardo Santos; CASTRO, Fábio Fernandes Morato- IgE and IgG4 Epitopes of Dermatophagoides and Blomia Allergens before and after Sublingual Immunotherapy(2023) FIGO, Daniele Danella; MACEDO, Priscilla Rios Cordeiro; GADERMAIER, Gabriele; REMUZGO, Cesar; CASTRO, Fabio Fernandes Morato; KALIL, Jorge; GALVAO, Clovis Eduardo Santos; SANTOS, Keity SouzaSublingual immunotherapy (SLIT) is used worldwide to treat house dust mites (HDM) allergy. Epitope specific immunotherapy with peptide vaccines is used far less, but it is of great interest in the treatment of allergic reactions, as it precludes the drawbacks of allergen extracts. The ideal peptide candidates would bind to IgG, blocking IgE-binding. To better elucidate IgE and IgG4 epitope profiles during SLIT, sequences of main allergens, Der p 1, 2, 5, 7, 10, 23 and Blo t 5, 6, 12, 13, were included in a 15-mer peptide microarray and tested against pooled sera from 10 patients pre- and post-1-year SLIT. All allergens were recognized to some extent by at least one antibody isotype and peptide diversity was higher post-1-year SLIT for both antibodies. IgE recognition diversity varied among allergens and timepoints without a clear tendency. Der p 10, a minor allergen in temperate regions, was the molecule with more IgE-peptides and might be a major allergen in populations highly exposed to helminths and cockroaches, such as Brazil. SLIT-induced IgG4 epitopes were directed against several, but not all, IgE-binding regions. We selected a set of peptides that recognized only IgG4 or were able to induce increased ratios of IgG4:IgE after one year of treatment and might be potential targets for vaccines.
