conferenceObject Inhaled corticoids in asthmatic patients: effect on body mass index and spirometry(2018) PACHECO, Rosilane dos Reis; ANDRADE, Mayra Coutinho; PEDROSO, Natalia Falci; TAKEJIMA, Priscila; AUN, Marcelo V.; KALIL FILHO, Jorge Elias; GIAVINA-BIANCHI, Pedro; AGONDI, Rosana C.conferenceObject Esophagogastroduodenal Mucosal Behavior after Bronchial Challenge with House Dust Mites in Allergic Asthmatic Patients(2015) AGONDI, Rosana C.; NAVARRO-RODRIGUEZ, Tomas; BARBUTI, Ricardo; BISACCIONI, Carla; AUN, Marcelo Vivolo; KALIL, Jorge; GIAVINA-BIANCHI, Pedro- Spirometric values in elderly asthmatic patients are not influenced by obesity(2012) AGONDI, R. C.; BISACCIONI, C.; AUN, M. V.; RIBEIRO, M. R.; KALIL, J.; GIAVINA-BIANCHI, P.Background Studies have suggested that asthma in obese individuals differs from the classic asthma phenotype, presenting as a disease that is more difficult to control. Objective The objective of the present study was to determine whether obesity, age or a combination of the two are associated with worse spirometry parameters in patients with asthma. Methods This was an observational cross-sectional study involving patients over 18 years of age who had been diagnosed with asthma (allergic or nonallergic). We evaluated the results of their spirometric tests. The patients were classified in accordance with two criteria: body mass index (BMI) and age. Based on their BMIs, the patients were divided into three groups: normal weight, overweight and obese. Patients were also separated into two categories by age: 18-59 years of age; and >= 60 years of age. Results We evaluated 451 patients with asthma and their spirometry tests. In the present study, the pulmonary function parameters were negatively correlated with BMI and age (P < 0.05). We found that there was a statistically significant correlation between spirometric values and BMI among patients 18-59 years of age (P < 0.001), however, among patients over 60, we did not observe this negative association. Conclusions and Clinical Relevance The spirometric values decreased significantly in proportion to the increase of BMI and age in patients with asthma, especially among young adults. There was no negative correlation between BMI and FEV1 in the group >= 60 years of age, suggesting that perhaps the time of disease is a major factor in the loss of lung function than weight gain in the elderly.
- Vocal cord dysfunction diagnosis may be improved by a screening check list(2016) PINTO, Lucia Helena Eduardo; AUN, Marcelo Vivolo; CUKIER-BLAJ, Sabrina; STELMACH, Rafael; CUKIER, Alberto; KALIL, Jorge; AGONDI, Rosana Camara; GIAVINA-BIANCHI, PedroBackground: Many patients with vocal cord dysfunction (VCD), with or without asthma, receive inappropriate treatment because they are misdiagnosed as having difficult-to-control asthma alone. We developed a clinical screening check list designed to aid the diagnosis of VCD. Methods: A prospective observational study involving 80 patients aged >= 8 years, diagnosed with severe asthma. After anamnesis and physical examination, physicians completed a check list with 6 questions to identify VCD, for which the answer ""yes"" counted one point. Then patients underwent spirometry and laryngoscopy. On the basis of the laryngoscopic findings, we created three patient groups: VCD (vocal cord adduction during inspiration, n = 14); unconfirmed VCD (inconclusive findings, n = 29); and control (normal findings, n = 37). We attempted to determine whether any of those groups were associated with the responses to individual questions or sets of questions on the check list. Results: The proportion of affirmative answers to the question ""Does pulmonary auscultation reveal wheezing, predominantly in the cervical region, and/or stridor?"" was significantly higher for the VCD group than for the other two groups (P = 0.006), notably in elderly patients. The variable ""4 or more affirmative answers"" was more common in VCD and unconfirmed VCD groups in comparison to controls (P = 0.022). Conclusions: A finding of wheezing or stridor on auscultation of the cervical region is suggestive of vocal cord dysfunction, especially in elderly patients, and such dysfunction can be confirmed through laryngoscopy. Our VCD screening check list proved to be useful in the screening of VCD among patients with severe asthma.
- Diagnosis and treatment of systemic mastocytosis in Brazil: Recommendations of a multidisciplinary expert panel(2022) VELLOSO, Elvira D. Rodrigues Pereira; PADULLA, Georgia A.; CERQUEIRA, Ana Maria Mosca de; SOUSA, Adriana Martins de; SANDES, Alex Freire; TRAINA, Fabiola; SEGURO, Fernanda Salles; NOGUEIRA, Frederico Lisboa; PEREIRA, Grazielly de Fathima; BOECHAT, jose Laerte; PAGNANO, Katia Borgia Barbosa; MARCHI, Luan Lima; ENSINA, Luis Felipe; GIAVINA-BIANCHI, Mara; AUN, Marcelo Vivolo; AGONDI, Rosana Camara; SANTOS, Fabio Pires de Souza; GIAVINA-BIANCHI, PedroIntroduction: Systemic Mastocytosis comprises a group of neoplastic diseases character-ized by clonal expansion and infiltration of mast cells into several organs. The diagnosis and treatment of this disease may be challenging for non-specialists. Objective: Make suggestions or recommendations in Systemic Mastocytosis based in a panel of Brazil-ian specialists.Method and results: An online expert panel with 18 multidisciplinary specialists was con-vened to propose recommendations on the diagnosis and treatment of Systemic Mastocy-tosis in Brazil. Recommendations were based on discussions of topics and multiple-choice questions and were graded using the Oxford Centre for Evidence-Based Medicine 2011 Lev-els of Evidence Chart. Conclusion: Twenty-two recommendations or suggestions were proposed based on a litera-ture review and graded according to the findings.(c) 2022 Associacao Brasileira de Hematologia, Hemoterapia e Terapia Celular.
conferenceObject Characterization of Asthmatic Patients with Vocal Cord Dysfunction(2013) AGONDI, Rosana C.; GALVAO, Violeta; AUN, Marcelo; BISACCIONI, Carla; KALIL, Jorge; GIAVINA-BIANCHI, PedroRATIONALE: The vocal cord dysfunction (VCD) is a syndrome characterized by paradoxical movement of the vocal folds that causes respiratory distress. Our goal is to analyze asthmatic patients with VCD. METHODS: This was an observational and cross-sectional study involving patients over 18 years of age who had been diagnosed with asthma according to the Global Initiative for Asthma guidelines. Eighty-five patients were analyzed. They were submitted to spirometry, and tested for total and specific IgE to aeroallergens (skin prick test and/or in vitro ). RESULTS: The mean age was 52.1 years, and 93% were female. Sixty- seven patients had moderate or severe persistent asthma. Spirometry was normal or showed mild obstructive respiratory disease in 81% of them. Spirometric alterations suggestive of VCD were observed in 24% of the patients. The mean serum total IgE was 303 IU/mL and the detection of specific IgE was present in 76% of them. Gastroesophageal reflux disease was observed in 65% of the patients. When classified according to gender, we found that men were younger, had higher total IgE and higher prevalence of specific IgE. CONCLUSIONS: There was a higher prevalence of the association asthma and VCD in women, suggesting that this association could be masked in men. However, we observed that the clinical characteristics were different between men and women. We found a high prevalence of atopy that could be another confounding factor. There was a weak association between asthma and spirometric severity classifications, suggesting a potential role for VCD in making difficult to the asthma control in some patients.- Debate on drugs that may aggravate COVID-19(2020) GIAVINA-BIANCHI, Pedro; AUN, Marcelo Vivolo; AGONDI, Rosana C.

conferenceObject New Associations Between HLA Genotypes and Asthma Phenotypes(2016) TAKEJIMA, Priscila Megumi; AGONDI, Rosana C.; RODRIGUES, Helcio; AUN, Marcelo Vivolo; KALIL, Jorge; GIAVINA-BIANCHI, PedroconferenceObject Diagnosis and treatment of AERD: clinical practice realities(2018) DIAS, Gabriella Melo Fontes Silva; ASSIS, Joao Paulo de; ANDRADE, Mayra Coutinho; CASTRO, Raisa Borges; MOUCO, Claudia Castilho; ZANANDREA, Andressa; AUN, Marcelo V.; KALIL, Jorge; GIAVINA-BIANCHI, Pedro; AGONDI, Rosana C.- Clinical, functional and inflammatory evaluation in asthmatic patients after a simple short-term educational program: a randomized trial(2021) FELIX, Soraia Nogueira; AGONDI, Rosana Camara; AUN, Marcelo Vivolo; OLIVO, Clarice Rosa; ALMEIDA, Francine Maria de; AMORIM, Thais Santos; CEZARIO, Julia Caroline; GIAVINA-BIANCHI, Pedro; TIBERIO, Iolanda de Fatima Lopes Calvo; MARTINS, Milton de Arruda de; ROMANHOLO, Beatriz Mangueira SaraivaThis study aimed to evaluate the clinical evolution, functional parameters and inflammatory activity of asthma in patients who submitted to an educational intervention. 58 adult patients over 18 years of age with partly controlled and uncontrolled asthma were randomized into an intervention group (IG) (N = 32) and a control group (CG) (N = 26) and evaluated for 12 weeks. The Asthma Control Test (ACT), Asthma Control Questionnaire (ACQ), Asthma Quality Life Questionnaire (AQLQ) and Beck Depression Inventory (BDI) questionnaires were applied. Spirometry, exhaled nitric oxide (NO), exhaled breath condensate (EBC) and induced sputum (IS), measurement of the peak flow and symptoms were performed. The IG patients received an educational activity for 30 min applied by a nurse. Statistical analysis: analysis of variance with repeated intragroup measures. IG presented a decreased number of eosinophils in IS and IL-17A in EBC, an increase in the percentage of FEV1 before and after bronchodilator and an improvement in quality of life compared to the CG. There was an improvement in depression levels and a decrease in IL-4 and IL-5 in the IS and in the EBC in both groups. Our results suggest that an educational intervention can bring benefits concerning the control of inflammation, lung function alterations, quality of life and levels of depression in asthmatic patients.
