This study brings further evidence that upper airway diseases are an important component of the asthma syndrome. Furthermore, monitoring of nasal eosinophilia by quantitative cytology may be useful as a surrogate of sputum cytology in as a component of composite measurement for determining airway inflammation.
Objective: There is evidence that asthma is associated with an increase in psychiatric symptoms and mental disorders. This association can make it difficult to achieve asthma control. The purpose of this study was to determine whether the level of asthma control is associated with anxiety and depression. Methods: A crosssectional study involving 78 patients with confirmed moderate or severe asthma and under regular treatment at the Asthma Outpatient Clinic of the Federal University of São Paulo Hospital São Paulo, in the city of São Paulo, Brazil.The patients were divided into two groups by asthma control status, as assessed by the asthma control test, and were subsequently compared in terms of demographic, clinical, and spirometric data, as well as scores for asthma quality of life and hospital anxiety/depression. Results: The sample was predominantly female. Of the 78 patients, 49 (63%) were classified as having uncontrolled asthma. The prevalence of anxiety and of anxiety+depression was significantly higher among patients with uncontrolled asthma than among those with controlled asthma (78% and 100%; p = 0.04 and p = 0.02, respectively), whereas there were no differences between the two groups in terms of the prevalence of depression, spirometry results, or quality of life score. Conclusions: In this sample, the prevalence of anxiety symptoms was higher in the patients with uncontrolled asthma than in those with controlled asthma.In the evaluation of asthma patients, the negative impact of mood states ought to be taken into consideration when asthma control strategies are being outlined.Keywords: Asthma; Anxiety; Depression; Cross-sectional studies. ResumoObjetivo: Existem evidências da associação entre asma e sintomas psiquiátricos e transtornos mentais. Essa associação pode resultar em dificuldades de se atingir o controle da asma. O objetivo deste estudo foi avaliar a associação de ansiedade e depressão com o controle da asma. Métodos: Estudo transversal com 78 pacientes asmáticos com diagnóstico confirmado de asma moderada a grave e regularmente tratados no Ambulatório de Asma do Hospital São Paulo da Universidade Federal de São Paulo, São Paulo (SP).Os pacientes foram divididos em dois grupos em relação ao status de controle de asma, determinado através do teste de controle da asma, e, posteriormente, comparados em termos de dados demográficos, clínicos e espirométricos, escore do questionário de qualidade de vida para asma e escore da escala hospitalar de ansiedade e depressão. Resultados: A maioria era do sexo feminino. Dos 78 pacientes, 49 (63%) foram classificados como tendo asma não controlada. A prevalência de ansiedade e do binômio ansiedade/depressão foi significantemente maior entre os pacientes não controlados do que nos controlados (78% e 100%; p = 0,04 e p = 0,02, respectivamente), enquanto nem prevalência de depressão, nem os dados espirométricos ou de qualidade de vida diferiram entre os grupos. Conclusões: Nesta amostra, os pacientes com asma não controlada apresentaram uma maior p...
Background and objective: Determination of asthma phenotypes, particularly inflammatory phenotypes, helps guide treatment and management of this heterogeneous disease. Induced sputum cytology has been the gold standard for determination of inflammatory phenotypes, but sputum induction is fairly invasive and technically challenging. Blood and nasal lavage cytology have been suggested as substitutes, but have not been fully verified. The aim of this study is to determine the accuracy of blood and nasal lavage cytometry as indicators of inflammatory phenotypes in asthma. Methods: Clinical evaluation, Asthma Control Questionnaire (ACQ) and spirometry were performed for 121 adult asthma patients, and blood, nasal lavage and induced sputum samples were taken. Eosinophils and neutrophils were counted in three samples from each subject. Inflammatory phenotypes (eosinophilic, neutrophilic, mixed and paucicellular) and cells counts were analysed using Venn diagram and receiver operating characteristic (ROC) curve, respectively. Results: ACQ score, spirometry and bronchodilator response did not differ among subjects with different inflammatory phenotypes. Inflammatory phenotypes defined by nasal lavage cytometry were in better concordance than those defined by blood cell counts with phenotypes determined by sputum cytology, and were significantly correlated with sputum phenotypes. For eosinophilia, nasal lavage cytology showed better accuracy than blood cytology (area under the curve (AUC): 0.89 vs 0.65). For all phenotypes, sensitivity and positive and negative predictive power were higher for nasal lavage cytometry than for blood. Blood cell counts gave a high level of false positives for all inflammatory phenotypes. Conclusion: We recommend nasal lavage cytology over blood cell count as a substitute for sputum cytology to identify inflammatory phenotypes in asthma.
The authors wish to make a correction concerning ROC curve presented in Fig. 2 of a recent publication in Clinical & Experimental Allergy [1]. The amendment does not in any way alter the conclusions of the original report. The findings of ROC curve were presented in this attached figure, where the sensitivity and specificity is 73% and 94%, respectively.
