Resumo: The main goal of asthma treatment is to achieve and maintain clinical control of the disease. The exhaled fraction nitric oxide (FeNO) level is considered a biomarker of airways inflammation and its important to conduct researches involving this measured and its relationship in evaluation of asthma control.Objective: To determine whether the FeNO level can be used to discriminate between patients with controlled, partially controlled and uncontrolled asthma. Materials and methods: The FeNO level and asthma control were evaluated in a retrospective and analytic cross– sectional study through data collected from asthmatic patients who were assessed by clinical history, asthma control, physical examination, spirometry, and FeNO level. Asthma control was determined by the criteria of the Global Initiative for Asthma, and classified as controlled asthma, partially controlled asthma, and uncontrolled asthma. The FeNO values were classified as low (<25 ppb) or intermediate/high (≥25 ppb), based on the American Thoracic Society recommendations. Results: The symptoms of 81 asthmatic patients were classified as controlled (34 [42%] patients), partially controlled (27 [33,3%] patients), and uncontrolled (20 [24.7%] patients). The FeNO level discriminated between the uncontrolled and controlled groups (p = 0,01) and between the uncontrolled and partially controlled groups (p = 0,01), but not between the controlled and partially controlled groups (p = 0,98). An FeNO level >30 ppb was associated with uncontrolled asthma (p < 0,01) with an area under the receiver operating characteristic curve of 0,78 (95% confidence interval, 0,65-0,89). Conclusions: The FeNO level aided the identification of uncontrolled asthma. This measurement may can be helpful in determining asthma control.

A medida da Fração Exalada do Óxido Nítrico (FeNO) é considerada um biomarcador da inflamação das vias aéreas sendo de extrema importância a realização de pesquisas envolvendo essa medida e a avaliação do nível de controle da asma. Objetivo: Verificar se a medida da FeNO discrimina pacientes com asma controlada, parcialmente controlada e não controlada. Materiais e métodos: Realizou-se um estudo restrospectivo, transversal analítico por meio da coleta de dados de pacientes asmáticos que foram avaliados em relação a sua história clínica, nível de controle da asma, exame físico, espirometria e FeNO. O nível de controle da asma foi determinado conforme critério da Global Initiative for Asthma (GINA), classificados como controlados, parcialmente controlados e não controlados. Os valores da FeNO foram classificados em baixo ou intermediário/alto (baixo <25 ppb e intermediário/elevado ≥ 25 ppb), de acordo com as recomendações da American Thoracic Society (ATS). Resultados: Foram incluídos 81 pacientes asmáticos classificados em controlados 34 (42%), parcialmente controlados 27 (33,3%) e não controlados 20 (24,7%). A medida da FeNO discriminou o grupo não controlado dos grupos controlado (p = 0,01) e parcialmente controlado (p = 0,01), mas não discriminou os grupos controlado e parcialmente controlado (p = 0,98). FENO >30 estava associado a asma não controlada (p <0,01) com área sob a curva ROC de 0,78 (Intervalo de Confiança 95%, 0.65- 0.89).Conclusão: A FeNO foi capaz de identificar asmáticos não controlados. Isso sugere que sua medida pode ser útil na determinação do controle da asmaSubmitted by Cássia Santos (cassia.bcufg@gmail.com) on 2016-12-16T10:18:59Z No. of bitstreams: 2 Dissertação - Fernanda Cruvinel de Abreu - 2016.pdf: 9557097 bytes, checksum: 68075f9112c44b45bbb05a915e471610 (MD5) license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5)Approved for entry into archive by Jaqueline Silva (jtas29@gmail.com) on 2016-12-16T16:48:58Z (GMT) No. of bitstreams: 2 Dissertação - Fernanda Cruvinel de Abreu - 2016.pdf: 9557097 bytes, checksum: 68075f9112c44b45bbb05a915e471610 (MD5) license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5)Made available in DSpace on 2016-12-16T16:48:59Z (GMT).
