Asthma control and health related quality of life are an important goal of asthma management, but their association with sputum eosinophilic inflammation has been less firmly established. To investigate the relationship of asthma control and quality of life with sputum eosinophils in clinical practice. Cross-sectional study with a convenience sample, including patients with asthma, aged between 18 and 65 years, attending to outpatient clinic. Patients underwent sputum induction, pulmonary function tests, Juniper's Asthma Quality of Life Questionnaire (AQLQ), Asthma Control Test (ACT), Global Initiative for Asthma (GINA) criteria for evaluation of asthma control and severity of the disease, blood count analysis, serum IgE and cutaneous prick test. Sputum sample was considered as eosinophilic if the percentage of eosinophils was ≥ 3%. A total of 45 individuals were enrolled, 15 with eosinophilic sputum (≥ 3% eosinophil cells) and 30 with non-eosinophilic sputum (< 3% eosinophil cells). There were no association of ACT an AQLQ scores with sputum eosinophilia (p > 0.05). This study suggested that the finding of sputum eosinophilia was not related to asthma control neither with health-related quality of life in patients with severe asthma.

OBJECTIVE: To investigate the impact of impaired pulmonary function on patient-centered outcomes after hospital discharge due to severe COVID-19 in patients without preexisting respiratory disease. METHODS: This is an ongoing prospective cohort study evaluating patients (> 18 years of age) 2-6 months after hospital discharge due to severe COVID-19. Respiratory symptoms, health-related quality of life, lung function, and the six-minute walk test were assessed. A restrictive ventilatory defect was defined as TLC below the lower limit of normal, as assessed by plethysmography. Chest CT scans performed during hospitalization were scored for the presence and extent of parenchymal abnormalities. RESULTS: At a mean follow-up of 17.2 ± 5.9 weeks after the diagnosis of COVID-19, 120 patients were assessed. Of those, 23 (19.2%) reported preexisting chronic respiratory diseases and presented with worse lung function and exertional dyspnea at the follow-up visit in comparison with their counterparts. When we excluded the 23 patients with preexisting respiratory disease plus another 2 patients without lung volume measurements, a restrictive ventilatory defect was observed in 42/95 patients (44%). This subgroup of patients (52.4% of whom were male; mean age, 53.9 ± 11.3 years) showed reduced resting gas exchange efficiency (DLCO), increased daily-life dyspnea, increased exertional dyspnea and oxygen desaturation, and reduced health-related quality of life in comparison with those without reduced TLC (50.9% of whom were male; mean age, 58.4 ± 11.3 years). Intensive care need and higher chest CT scores were associated with a subsequent restrictive ventilatory defect. CONCLUSIONS: The presence of a restrictive ventilatory defect approximately 4 months after severe COVID-19 in patients without prior respiratory comorbidities implies worse clinical outcomes.

Cystic fibrosis (CF) is a genetic disease that results in dysfunction of the CF transmembrane conductance regulator (CFTR) protein, which is a chloride and bicarbonate channel expressed in the apical portion of epithelial cells of various organs. Dysfunction of that protein results in diverse clinical manifestations, primarily involving the respiratory and gastrointestinal systems, impairing quality of life and reducing life expectancy. Although CF is still an incurable pathology, the therapeutic and prognostic perspectives are now totally different and much more favorable. The purpose of these guidelines is to define evidence-based recommendations regarding the use of pharmacological agents in the treatment of the pulmonary symptoms of CF in Brazil. Questions in the Patients of interest, Intervention to be studied, Comparison of interventions, and Outcome of interest (PICO) format were employed to address aspects related to the use of modulators of this protein (ivacaftor, lumacaftor+ivacaftor, and tezacaftor+ivacaftor), use of dornase alfa, eradication therapy and chronic suppression of Pseudomonas aeruginosa, and eradication of methicillin-resistant Staphylococcus aureus and Burkholderia cepacia complex. To formulate the PICO questions, a group of Brazilian specialists was assembled and a systematic review was carried out on the themes, with meta-analysis when applicable. The results obtained were analyzed in terms of the strength of the evidence compiled, the recommendations being devised by employing the GRADE approach. We believe that these guidelines represent a major advance to be incorporated into the approach to patients with CF, mainly aiming to favor the management of the disease, and could become an auxiliary tool in the definition of public policies related to CF.

RESUMO A fibrose cística (FC) é uma doença genética que resulta em disfunção da proteína reguladora de condutância transmembrana da FC (CFTR), que é um canal de cloro e bicarbonato expresso na porção apical de células epiteliais de diversos órgãos. A disfunção dessa proteína resulta em manifestações clínicas diversas, envolvendo primariamente os sistemas respiratório e gastrointestinal com redução da qualidade e expectativa de vida. A FC ainda é uma patologia incurável, porém o horizonte terapêutico e prognóstico é hoje totalmente distinto e muito mais favorável. O objetivo destas diretrizes foi definir recomendações brasileiras baseadas em evidências em relação ao emprego de agentes farmacológicos no tratamento pulmonar da FC. As perguntas PICO (acrônimo baseado em perguntas referentes aos Pacientes de interesse, Intervenção a ser estudada, Comparação da intervenção e Outcome [desfecho] de interesse) abordaram aspectos relativos ao uso de moduladores de CFTR (ivacaftor, lumacaftor + ivacaftor e tezacaftor + ivacaftor), uso de dornase alfa, terapia de erradicação e supressão crônica de Pseudomonas aeruginosa, e erradicação de Staphylococcus aureus resistente a meticilina e do complexo Burkholderia cepacia. Para a formulação das perguntas, um grupo de especialistas brasileiros foi reunido e realizou-se uma revisão sistemática sobre os temas, com meta-análise quando aplicável. Os resultados encontrados foram analisados quanto à força das evidências compiladas, sendo concebidas recomendações seguindo a metodologia GRADE. Os autores acreditam que o presente documento represente um importante avanço a ser incorporado na abordagem de pacientes com FC, objetivando principalmente favorecer seu manejo, podendo se tornar uma ferramenta auxiliar na definição de políticas públicas relacionadas à FC.

RESUMO Objetivo: Investigar o impacto do comprometimento da função pulmonar nos desfechos centrados no paciente após a alta hospitalar em pacientes sem doenças respiratórias preexistentes que foram hospitalizados em virtude de COVID-19 grave. Métodos: Trata-se de um estudo prospectivo de coorte em andamento, no qual pacientes com COVID-19 grave (com idade > 18 anos) são avaliados 2-6 meses depois da alta hospitalar. Avaliamos os sintomas respiratórios, a qualidade de vida relacionada à saúde, a função pulmonar e a distância percorrida no teste de caminhada de seis minutos. A definição de distúrbio ventilatório restritivo foi CPT abaixo do limite inferior da normalidade na pletismografia. As imagens de TC de tórax realizadas durante a hospitalização foram avaliadas quanto à presença e extensão de alterações parenquimatosas. Resultados: Em média 17,2 ± 5,9 semanas depois do diagnóstico de COVID-19, foram avaliados 120 pacientes. Destes, 23 (19,2%) relataram doenças respiratórias crônicas preexistentes e apresentaram pior função pulmonar e maior dispneia aos esforços na consulta de acompanhamento quando comparados aos outros participantes. Quando excluímos os 23 pacientes com doenças respiratórias preexistentes e mais 2 pacientes (sem medidas de volumes pulmonares), observamos distúrbio ventilatório restritivo em 42/95 pacientes (44%). Esse subgrupo de pacientes (52,4% dos quais eram do sexo masculino, com média de idade de 53,9 ± 11,3 anos) apresentou menor eficiência das trocas gasosas (DLCO), maior dispneia na vida diária e dessaturação de oxigênio ao exercício e redução da qualidade de vida relacionada à saúde em comparação com aqueles sem redução da CPT (50,9% dos quais eram do sexo masculino, com média de idade de 58,4 ± 11,3 anos). A necessidade de terapia intensiva e pontuações mais altas no escore de alterações parenquimatosas na TC de tórax apresentaram relação com distúrbio ventilatório restritivo subsequente. Conclusões: A presença de distúrbio ventilatório restritivo aproximadamente 4 meses depois da COVID-19 grave em pacientes sem comorbidades respiratórias prévias implica piores desfechos clínicos.
RESUMO
OBJECTIVE: There is still limited information on the clinical characteristics and outcomes of cystic fibrosis (CF) patients with COVID-19 in Brazil. The objective of this study was to describe the cumulative incidence of COVID-19 in CF patients, as well as their clinical characteristics and outcomes. METHODS: This was a prospective cohort study involving unvaccinated adult CF patients and conducted during the first year of the SARS-CoV-2 pandemic in the city of Porto Alegre, in southern Brazil. The clinical course of the disease was rated on the WHO Ordinal Scale for Clinical Improvement. The primary outcome was the number of incident cases of COVID-19. RESULTS: Between April 30, 2020 and April 29, 2021, 98 CF patients were included in the study. Seventeen patients were diagnosed with COVID-19. For the CF patients, the annual cumulative incidence of COVID-19 was 17.3%, similar to that for the general population, adjusted for age (18.5%). The most common symptoms at diagnosis of COVID-19 were cough (in 59%), dyspnea (in 53%), fatigue (in 53%), and fever (in 47%). Only 6 (35%) of the patients required hospitalization, and 3 (17.6%) required oxygen support. Only 1 patient required mechanical ventilation, having subsequently died. CONCLUSIONS: During the first year of the SARS-CoV-2 pandemic in southern Brazil, the cumulative incidence rate of COVID-19 was similar between CF patients and the general population. More than 50% of the CF patients with SARS-CoV-2 infection had a mild clinical presentation, without the need for hospital admission, and almost the entire sample recovered completely from the infection, the exception being 1 patient who had advanced lung disease and who died.

Abstract Objective: In this present study, the authors evaluated the predictive factors for adverse maternal-fetal outcomes in pregnancies of women with cystic fibrosis (CF). Patients were followed up by a referral center for adults in southern Brazil. Methods: This is a retrospective cohort study that used data from electronic medical records regarding pregnancies of women diagnosed with CF. Results: The study included 39 pregnancies related to 20 different women. The main adverse outcomes were high prevalence rates of premature birth (38.5%) and maternal respiratory exacerbation (84.6%). Lower body mass index (BMI) values (< 20.8) and younger ages of CF diagnosis increased the risk of premature birth. The presence of methicillin-resistant and absence of methicillin-sensitive Staphylococcus aureus, as well as a younger age of diagnosis, increased the risk of maternal respiratory exacerbation during pregnancy. Conclusions: Conception in women with CF is often associated with maternal and fetal complications. Continuous monitoring by a multidisciplinary team should emphasize appropriate nutritional status, investigation of bacterial colonization, and immediate attention to respiratory exacerbations.

RESUMO Objetivo: Ainda não há informações suficientes sobre as características clínicas e desfechos de pacientes com fibrose cística (FC) e COVID-19 no Brasil. O objetivo deste estudo foi descrever a incidência cumulativa de COVID-19 em pacientes com FC, bem como suas características clínicas e desfechos. Métodos: Estudo prospectivo de coorte com adultos com FC não vacinados, realizado na cidade de Porto Alegre, no sul do Brasil, durante o primeiro ano da pandemia de SARS-CoV-2. A evolução clínica da COVID-19 foi avaliada por meio da WHO Ordinal Scale for Clinical Improvement (escala ordinal de evolução clínica, elaborada pela OMS). O desfecho primário foi o número de casos incidentes de COVID-19. Resultados: Entre 30 de abril de 2020 e 29 de abril de 2021, 98 pacientes com FC foram incluídos no estudo. Dezessete pacientes receberam diagnóstico de COVID-19. Nos pacientes com FC, a incidência cumulativa anual de COVID-19 foi de 17,3%, semelhante à observada na população geral, ajustada pela idade (18,5%). Os sintomas mais comuns no momento do diagnóstico de COVID-19 foram tosse (em 59%), dispneia (em 53%), fadiga (em 53%) e febre (em 47%). Apenas 6 (35%) dos pacientes necessitaram de hospitalização, e 3 (17,6%) necessitaram de suporte de oxigênio. Apenas 1 paciente necessitou de ventilação mecânica e, posteriormente, morreu. Conclusões: Durante o primeiro ano da pandemia de SARS-CoV-2 no sul do Brasil, a taxa de incidência cumulativa de COVID-19 foi semelhante nos pacientes com FC e na população geral. Mais de 50% dos pacientes com FC e infecção por SARS-CoV-2 apresentaram manifestações clínicas leves, sem necessidade de internação hospitalar, e quase toda a amostra se recuperou completamente da infecção, à exceção de 1 paciente, que apresentava doença pulmonar avançada e morreu.
RESUMO
OBJECTIVE: Massive hemoptysis is one of the most serious complications in patients with cystic fibrosis (CF). This study aimed to evaluate the hemoptysis-free period following bronchial and non-bronchial artery embolization (BAE/non-BAE) in CF patients and to investigate predictors of recurrent bleeding and mortality by any cause. METHODS: This was a retrospective cohort study of CF patients ≥ 16 years of age undergoing BAE/non-BAE for hemoptysis between 2000 and 2017. RESULTS: We analyzed 39 hemoptysis episodes treated with BAE/non-BAE in 17 CF patients. Hemoptysis recurrence rate was 56.4%. Of the sample as a whole, 3 (17.6%) were hemoptysis-free during the study period, 2 (11.8%) underwent lung transplantation, and 3 (17.6%) died. The median hemoptysis-free period was 17 months. The median hemoptysis-free period was longer in patients with chronic infection with Pseudomonas aeruginosa (31 months; 95% CI: 0.00-68.5) than in those without that type of infection (4 months; 95% CI: 1.8-6.2; p = 0.017). However, this association was considered weak, and its clinical significance was uncertain due to the small number of patients without that infection. CONCLUSIONS: BAE appears to be effective in the treatment of hemoptysis in patients with CF.

Introduction: Consumption of foods with anti-inflammatory and antioxidant components could contribute to a better control of the asthma. The aim of this study was to assess the association between dietary patterns, nutritional status, and asthma control in patients treated at an asthma referral center in Porto Alegre, Brazil. Methods: This is a cross-sectional study with 198 adult asthma patients. Participants completed a 24-hour food recall and a questionnaire on disease history, degree of control, and severity, as well as pulmonary and anthropometric assessments. We used exploratory factor analysis and principal component analysis as an extraction method to derive the dietary patterns. Results: The mean body mass index was 29.6 (SD, 5.7) kg/m2, and 41.9% were classified as obese. Regarding disease severity, 72.7% were classified as having severe persistent asthma, and concerning the degree of control, 59.6% of the patients had uncontrolled asthma. Three dietary patterns were identified: "Sugars", "Healthy", and "Fats and Alcohol". It was observed that the Fats and Alcohol pattern was significantly associated with men. However, no associations were observed between the other variables and dietary patterns. Conclusion: This was the first study to identify the dietary patterns in asthmatics in Brazil. Patterns found in the present study were "Sugars", "Healthy" and "Fats and Alcohol". However, there was no significant association between the 3 patterns and nutritional status or disease control.

RESUMO Objetivo: A hemoptise maciça é uma das complicações mais graves em pacientes com fibrose cística (FC). O objetivo deste estudo foi avaliar o período livre de hemoptise após a embolização arterial brônquica/não brônquica (EAB/não EAB) em pacientes com FC e investigar preditores de sangramento recorrente e mortalidade por qualquer causa. Métodos: Trata-se de um estudo retrospectivo de coorte de pacientes com FC com idade ≥ 16 anos submetidos a EAB/não EAB para o tratamento de hemoptise entre 2000 e 2017. Resultados: Foram analisados 39 episódios de hemoptise tratada por meio de EAB/não EAB em 17 pacientes com FC. A taxa de recidiva da hemoptise foi de 56,4%. Do total de pacientes, 3 (17,6%) permaneceram sem hemoptise durante o estudo, 2 (11,8%) foram submetidos a transplante de pulmão e 3 (17,6%) morreram. A mediana do período sem hemoptise foi de 17 meses. A mediana do período sem hemoptise foi maior em pacientes com infecção crônica por Pseudomonas aeruginosa (31 meses; IC95%: 0,00-68,5) do que naqueles sem esse tipo de infecção (4 meses; IC95%: 1,8-6,2; p = 0,017). No entanto, essa associação foi considerada fraca, e sua importância clínica foi considerada incerta em virtude do pequeno número de pacientes sem essa infecção. Conclusões: A EAB parece ser eficaz no tratamento de hemoptise em pacientes com FC.

Identification of low dyspnea perception is relevant, since this condition is significantly associated with worse outcomes. We investigated dyspnea perception during the inspiratory resistive loads test on obese subjects waiting bariatric surgery in comparison with normal subjects. Secondarily, we analysed the proportion of obese subjects with low, moderate and high dyspnea perception. This observational study included subjects with body mass index (BMI) ≥ 35 kg/m2, compared to healthy subjects with BMI ≥ 18 and <25 kg/m2. Subject underwent clinical evaluation, inspiratory test with progressive resistive loads and spirometry. We studied 23 obese subjects (mean BMI = 51.9 ± 9.3 kg/m2) and 25 normal subjects (mean BMI = 24.3 ± 2.3 kg/m2). With the increase magnitude of resistive loads there was a significant increase in dyspnea score (p < 0.001) and progressive increase of the generated inspiratory pressure (p < 0.001), but there was no difference between the groups in terms of dyspnea score (p = 0.191) and no interaction effect (p = 0.372). Among the obese subjects, 4 individuals were classified as low perception, 11 as moderate and 8 as high. In conclusion, the degree of dyspnea perception during the inspiratory progressive resistive loads test did not differ between obese and normal subjects. Among obese subjects, only 17% were classified as low dyspnea perception.

OBJECTIVE: To evaluate the radiological presentation of patients with pulmonary tuberculosis diagnosed in the emergency department and to investigate its association with the time to diagnosis. METHODS: This was a prospective observational study involving patients diagnosed with pulmonary tuberculosis in the emergency department of a tertiary university hospital in southern Brazil. Chest X-rays taken on admission were evaluated by a radiologist. The various patterns of radiological findings and locations of the lesions were described. The main study outcome was the total time elapsed between the initial radiological examination and the diagnosis of tuberculosis. RESULTS: A total of 78 patients were included in the study. The median time from chest X-ray to diagnosis was 2 days, early and delayed diagnosis being defined as a time to diagnosis < 2 days and ≥ 2 days, respectively. Sputum smear positivity was associated with early diagnosis (p = 0.005), and positive culture was associated with delayed diagnosis (p = 0.005). Early diagnosis was associated with the presence of sputum (p = 0.03), weight loss (p = 0.047), cavitation (p = 0.001), and consolidation (p = 0.003). Pulmonary cavitation was found to be an independent predictor of early diagnosis (OR = 3.50; p = 0.028). CONCLUSIONS: There is a need for tuberculosis-specific protocols in emergency departments, not only to avoid delays in diagnosis and treatment but also to modify the transmission dynamics of the disease.
