ABSTRACT

ABSTRACT 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.

ABSTRACT

ABSTRACT 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.


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.

ABSTRACT

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.

ABSTRACT

ABSTRACT 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.


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.

ABSTRACT

ABSTRACT 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.


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.

ABSTRACT

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.

ABSTRACT

Abstract Introduction: Regular physical activity (PA) is part of outpatient care offered to most people with cystic fibrosis (CF). Objective: To determine the frequency of the self-reported PA and, secondarily evaluate associations between PA with clinical variables and health-related quality of life (HRQoL) in pediatric and adolescent CF subjects. Method: In this cross-sectional study, subjects between 6 and 17 years of age with a confirmed diagnosis of CF were recruited in the outpatient clinic. The subjects answered questions about the practices of PA, HRQoL questionnaire and clinical variables were collected. Subjects were classified into two groups according to weekly PA practice: PA performed ≥ 3 times/week and performed PA ≤ 2 times/week. Results: 66 subjects completed the study, 72.7% (n=48) had PA ≥ 3 times/week and 27.2% (n=18) had PA ≤ 2 times/week. Only twelve children (18,2%) reached the recommendations of the World Health Organization (WHO) to practice moderate to vigorous physical activities daily. The mean age of the subjects evaluated was 12.3 ± 3.2 years, forced expiratory volume in one second 90 ± 24.1% and forced vital capacity 95 ± 20.4%. The group that performed PA ≥ 3 times/week had a better clinical score (p=0.033), a lower number of hospitalizations in the year (p=0.002), a lower number of days hospitalized in the last year (p=0.020) and better score for the physical (p=0.003) and emotion (p=0.048) domains in HRQoL questionnaire. Conclusion: This study concluded that most subjects did not reach the WHO recommendations for the practice of PA. However, individuals who practice PA at least 3 times/week have better HRQoL, clinical score and fewer hospitalizations.


Resumo Introdução: A atividade física regular (AF) faz parte do tratamento ambulatorial oferecido à maioria das pessoas com fibrose cística (FC). Objetivo: Determinar a frequência da AF autorreferida e secundariamente avaliar as associações entre AF e variáveis clínicas e de qualidade de vida relacionada à saúde (QVRS) em crianças e adolescentes com FC. Método: Neste estudo transversal, indivíduos entre 6 e 17 anos com diagnóstico confirmado de FC foram recrutados no ambulatório. Os sujeitos responderam perguntas sobre as práticas de AF, questionário de QVRS e variáveis clínicas. Os indivíduos foram classificados em dois grupos de acordo com a prática semanal de AF: AF realizada ≥3 vezes/semana e AF≤2 vezes/semana. Resultados: 66 indivíduos completaram o estudo, 72,7% (n=48) tinham AF ≥ 3 vezes/semana e 27,2% (n=18) tinham AF ≤ 2 vezes/semana. Apenas doze crianças (18,2%) alcançaram as recomendações da Organização Mundial da Saúde (OMS) para praticar diariamente atividades físicas moderadas a vigorosas. A média de idade dos sujeitos avaliados foi de 12,3 ± 3,2 anos, volume expiratório forçado no primeiro segundo 90 ± 24,1% e capacidade vital forçada 95 ± 20,4%. O grupo que realizou AF ≥ 3 vezes/semana apresentou melhor escore clínico (p=0,033), menor número de internações no ano (p=0,002), menor número de dias hospitalizados no último ano (p=0,020) e melhor escore para os domínios físico (p=0,003) e emoção (p=0,048) no questionário de QVRS. Conclusão: Este estudo concluiu que a maioria dos indivíduos não alcançou as recomendações da OMS para a prática de AF. No entanto, indivíduos que praticam AF pelo menos 3 vezes/semana apresentam melhor QVRS, escore clínico e menos hospitalizações.

ABSTRACT

ABSTRACT 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.


RESUMO Objetivo: Avaliar a apresentação radiológica de pacientes com tuberculose pulmonar diagnosticada no serviço de emergência e investigar sua associação com o tempo para o diagnóstico. Métodos: Estudo observacional prospectivo envolvendo pacientes diagnosticados com tuberculose pulmonar no serviço de emergência de um hospital universitário terciário no sul do Brasil. As radiografias de tórax realizadas na admissão foram avaliadas por um radiologista. Foram descritos os diferentes padrões de achados radiológicos e as localizações das lesões. O desfecho principal do estudo foi o tempo total decorrido entre o exame radiológico inicial e o diagnóstico de tuberculose. Resultados: Um total de 78 pacientes foi incluído no estudo. A mediana de tempo entre a radiografia de tórax e o diagnóstico foi de 2 dias, sendo os diagnósticos precoce e tardio definidos como tempo para o diagnóstico < 2 dias e ≥ 2 dias, respectivamente. A positividade da baciloscopia de escarro associou-se ao diagnóstico precoce (p = 0,005), e a cultura positiva associou-se ao diagnóstico tardio (p = 0,005). O diagnóstico precoce associou-se à presença de escarro (p = 0,03), perda de peso (p = 0,047), cavitação (p = 0,001) e consolidação (p = 0,003). A cavitação pulmonar foi um preditor independente de diagnóstico precoce (OR = 3,50; p = 0,028). Conclusões: Há necessidade de protocolos específicos para tuberculose nos serviços de emergência, não apenas para evitar atrasos no diagnóstico e no tratamento, mas também para modificar a dinâmica de transmissão da doença.

ABSTRACT

Introduction: Inhalation therapy is a crucial part of the cystic fibrosis (CF) treatment regimen. Drugs that assist in mucociliary clearance and inhaled antibiotics are used by most patients. Methods: This is a cross-sectional study where patients with CF and their caregivers answered questionnaires regarding their adherence to inhalation therapy and QoL. Demographic, spirometric, and bacteriological data, as well as S-K scores and hospitalization frequencies were also collected. Results: We included 66 patients in this study; participants had a mean age of 12.3 years and Z-scores of -1.4 for forced expiratory volume in 1 second and 48.6 for body mass index. Patients were divided into 2 groups according to their self-reported adherence to inhalation therapy: high adherence (n = 46) and moderate/low adherence (n = 20). When comparing both groups, there was no statistically significant differences in age, sex, family income, and S-K score (p > 0.05). The high-adherence group had had shorter hospitalization periods in the previous year (p = 0.016) and presented better scores in the following domains of the QoL questionnaire: emotion (p = 0.006), eating (p = 0.041), treatment burden (p = 0.001), health perception (p = 0.001), and social (p = 0.046). Conclusions: A low self-reported adherence to inhalation therapy recommendations was associated with longer hospitalizations in the previous year and with a decrease in QoL in pediatric patients with CF.

ABSTRACT

ABSTRACT Bronchiectasis is a condition that has been increasingly diagnosed by chest HRCT. In the literature, bronchiectasis is divided into bronchiectasis secondary to cystic fibrosis and bronchiectasis not associated with cystic fibrosis, which is termed non-cystic fibrosis bronchiectasis. Many causes can lead to the development of bronchiectasis, and patients usually have chronic airway symptoms, recurrent infections, and CT abnormalities consistent with the condition. The first international guideline on the diagnosis and treatment of non-cystic fibrosis bronchiectasis was published in 2010. In Brazil, this is the first review document aimed at systematizing the knowledge that has been accumulated on the subject to date. Because there is insufficient evidence on which to base recommendations for various treatment topics, here the decision was made to prepare an expert consensus document. The Brazilian Thoracic Association Committee on Respiratory Infections summoned 10 pulmonologists with expertise in bronchiectasis in Brazil to conduct a critical assessment of the available scientific evidence and international guidelines, as well as to identify aspects that are relevant to the understanding of the heterogeneity of bronchiectasis and to its diagnostic and therapeutic management. Five broad topics were established (pathophysiology, diagnosis, monitoring of stable patients, treatment of stable patients, and management of exacerbations). After this subdivision, the topics were distributed among the authors, who conducted a nonsystematic review of the literature, giving priority to major publications in the specific areas, including original articles, review articles, and systematic reviews. The authors reviewed and commented on all topics, producing a single final document that was approved by consensus.


RESUMO Bronquiectasias têm se mostrado uma condição cada vez mais diagnosticada com a utilização da TCAR de tórax. Na literatura, a terminologia utilizada separa as bronquiectasias entre secundárias à fibrose cística e aquelas não associadas à fibrose cística, denominadas bronquiectasias não fibrocísticas neste documento. Muitas causas podem levar ao desenvolvimento de bronquiectasias, e o paciente geralmente tem sintomas crônicos de vias aéreas, infecções recorrentes e alterações tomográficas compatíveis com a condição. Em 2010, foi publicada a primeira diretriz internacional sobre diagnóstico e tratamento das bronquiectasias não fibrocísticas. No Brasil, este é o primeiro documento de revisão com o objetivo de sistematizar o conhecimento acumulado sobre o assunto até o momento. Como para vários tópicos do tratamento não há evidências suficientes para recomendações, optou-se aqui pela construção de um documento de consenso entre especialistas. A Comissão de Infecções Respiratórias da Sociedade Brasileira de Pneumologia e Tisiologia reuniu 10 pneumologistas com expertise em bronquiectasias no Brasil para avaliar criticamente as evidências científicas e diretrizes internacionais, assim como identificar aspectos relevantes à compreensão da heterogeneidade da doença bronquiectásica e a seu manejo diagnóstico e terapêutico. Foram determinados cinco grandes tópicos (fisiopatologia; diagnóstico; monitorização do paciente estável; tratamento do paciente estável; e manejo das exacerbações). Após essa subdivisão, os tópicos foram distribuídos entre os autores, que realizaram uma revisão não sistemática da literatura, priorizando as principais publicações nas áreas específicas, incluindo artigos originais e de revisão, assim como revisões sistemáticas. Os autores revisaram e opinaram sobre todos os tópicos, formando um documento único final que foi aprovado por todos.

ABSTRACT

ABSTRACT Objective: To evaluate health-related quality of life in asthma patients treated at a referral center in southern Brazil, identifying differences between male and female patients, as well as to evaluate differences between the males and females in terms of asthma control, lung function, and nutritional status. Methods: This was a cross-sectional study involving patients ≥ 18 years of age treated at an asthma outpatient clinic. We evaluated clinical parameters, lung function, nutritional status, and quality of life. Results: A total of 198 patients completed the study. The mean age was 56.2 ± 14.8 years, and 81.8% were female. The proportion of patients with uncontrolled asthma was higher among females than among males (63.0% vs. 44.4%; p = 0.041). The body mass index (BMI) and percentage of body fat were higher in females than in males (30.2 ± 5.8 kg/m2 vs. 26.9 ± 4.5 kg/m2 and 37.4 ± 6.4% vs. 26.5 ± 7.4%; p = 0.002 and p < 0.001, respectively). Quality of life was lower in females than in males in the following domains: symptoms (3.8 ± 1.5 vs. 4.6 ± 1.7; p = 0.006); activity limitation (3.6 ± 1.3 vs. 4.4 ± 1.5; p = 0.001); emotional function (3.6 ± 1.9 vs. 4.5 ± 1.7; p = 0.014); and environmental stimuli (3.2 ± 1.6 vs. 4.3 ± 1.9; p = 0.001). Conclusions: Male asthma patients appear to fare better than do female asthma patients in terms of health-related quality of life, asthma control, BMI, percentage of body fat, and comorbidities.


RESUMO Objetivo: Avaliar a qualidade de vida relacionada à saúde em pacientes com asma tratados em um centro de referência no sul do Brasil e identificar diferenças entre homens e mulheres, além de avaliar as diferenças entre os sexos no tocante ao controle da asma, função pulmonar e estado nutricional. Métodos: Trata-se de um estudo transversal com pacientes com idade ≥ 18 anos tratados em um ambulatório de asma. Foram avaliados parâmetros clínicos, função pulmonar, estado nutricional e qualidade de vida. Resultados: Cento e noventa e oito pacientes completaram o estudo. A média de idade foi de 56,2 ± 14,8 anos, e 81,8% eram do sexo feminino. A proporção de pacientes com asma não controlada foi maior entre as mulheres que entre os homens (63,0% vs. 44,4%; p = 0,041). O índice de massa corporal (IMC) e a porcentagem de gordura corporal foram maiores nas mulheres que nos homens (30,2 ± 5,8 kg/m2 vs. 26,9 ± 4,5 kg/m2 e 37,4 ± 6,4% vs. 26,5 ± 7,4%; p = 0,002 e p < 0,001, respectivamente). A qualidade de vida foi menor nas mulheres que nos homens nos seguintes domínios: sintomas (3,8 ± 1,5 vs. 4,6 ± 1,7; p = 0,006); limitação das atividades (3,6 ± 1,3 vs. 4,4 ± 1,5; p = 0,001); função emocional (3,6 ± 1,9 vs. 4,5 ± 1,7; p = 0,014); estímulos ambientais (3,2 ± 1,6 vs. 4,3 ± 1,9; p = 0,001). Conclusões: Homens com asma aparentemente apresentam melhores resultados que mulheres com asma no que tange à qualidade de vida relacionada à saúde, controle da asma, IMC, porcentagem de gordura corporal e comorbidades.

ABSTRACT

RESUMO No período sazonal compreendido entre 2014 e 2015, a maior parte das infecções por influenza decorreu do vírus influenza A H3N2. Mais de dois terços dos vírus influenza A H3N2 circulante eram antigênica e geneticamente diferentes (drift) do componente A H3N2 da vacina da influenza sazonal 2014 - 2015 para os hemisférios norte e sul. O objetivo deste trabalho foi relatar um caso de infecção por influenza A sazonal não H1N1 ocorrido em junho de 2015 em um paciente adulto com fibrose cística com doença pulmonar grave, previamente vacinado com a vacina antigripal trivalente. O paciente evoluiu com insuficiências respiratória e renal (sem rabdomiólise), sendo submetido à ventilação mecânica e à hemodiálise. A evolução clínica foi positiva após 39 dias de permanência hospitalar. Ainda, o paciente permaneceu clinicamente estável após seguimento de 18 meses. Com os avanços recentes na medicina intensiva e no tratamento, a sobrevivência com uma doença pulmonar avançada na fibrose cística apresenta novas questões e problemas potenciais, que ainda estão sendo formulados.


ABSTRACT In the 2014 - 2015 season, most influenza infections were due to A (H3N2) viruses. More than two-thirds of circulating A (H3N2) viruses are antigenically and genetically different (drifted) from the A (H3N2) vaccine component of 2014 - 2015 northern and southern Hemisphere seasonal influenza vaccines. The purpose of this paper is to report a case of seasonal influenza A non-H1N1 infection that occurred in June 2015 in an adult cystic fibrosis patient with severe lung disease previously vaccinated with the anti-flu trivalent vaccine. The patient evolved to respiratory and renal failure (without rhabdomyolysis) and was placed under mechanical ventilation and hemodialysis. The clinical outcome was positive after 39 days of hospital stay. In addition, the patient was clinically stable after 18 months of follow-up. With the recent advances in critical care medicine and in cystic fibrosis treatment, survival with advanced pulmonary disease in cystic fibrosis presents new questions and potential problems, which are still being formulated.

ABSTRACT

ABSTRACT Objective: To determine the prevalence of malnutrition in patients attending an adult cystic fibrosis (CF) program and to investigate the associations of malnutrition with the clinical characteristics of those patients. Methods: This was a cross-sectional study involving patients with clinically stable CF patients (16 years of age or older). The patients underwent clinical assessment, nutritional assessments, pulmonary function tests, and pancreatic function assessment. They also completed a questionnaire regarding diet compliance. On the basis of their nutritional status, the patients were classified divided into three groups: adequate nutrition; at nutritional risk; and malnutrition. Results: The study has included 73 patients (mean age, 25.6 ± 7.3 years), 40 of whom (54.8%) were female. The mean body mass index was 21.0 ± 3.0 kg/m2 and the mean FEV1 was 59.7 ± 30.6% of predicted. In this sample of patients, 32 (43.8%), 23 (31.5%), and 18 (24.7%) of the patients were allocated to the adequate nutrition, nutritional risk, and malnutrition groups, respectively. The logistic regression analysis identified three independent factors associated with the risk of malnutrition: Shwachman-Kulczycki score, percent predicted FEV1; and age. Conclusions: Malnutrition remains a common complication in adolescents and adults with CF, despite dietary advice. Malnutrition is associated with age, clinical severity, and lung function impairment.


RESUMO Objetivo: Determinar a prevalência de desnutrição em pacientes de um programa para adultos com fibrose cística (FC) e investigar a relação da desnutrição com as características clínicas desses pacientes. Métodos: Trata-se de um estudo transversal com pacientes com FC clinicamente estáveis (com 16 anos de idade ou mais). Os pacientes foram submetidos a avaliação clínica, avaliação nutricional, testes de função pulmonar e avaliação da função pancreática. Eles também preencheram um questionário sobre sua adesão à dieta proposta. Os pacientes foram divididos em três grupos, de acordo com seu estado nutricional: nutrição adequada, risco nutricional e desnutrição. Resultados: O estudo incluiu 73 pacientes (média de idade: 25,6 ± 7,3 anos), dos quais 40 (54,8%) eram do sexo feminino. A média do índice de massa corporal foi de 21,0 ± 3,0 kg/m2, e a média do VEF1 foi de 59,7 ± 30,6% do previsto. Nessa amostra de pacientes, 32 (43,8%) ficaram no grupo com nutrição adequada, 23 (31,5%) ficaram no grupo com risco nutricional e 18 (24,7%) ficaram no grupo com desnutrição. A análise de regressão logística identificou três fatores independentes relacionados com o risco de desnutrição: escore de Shwachman-Kulczycki, VEF1 em % do previsto e idade. Conclusões: A desnutrição ainda é uma complicação comum em adolescentes e adultos com FC, não obstante o aconselhamento dietético. A desnutrição está relacionada com a idade, a gravidade clínica e o comprometimento da função pulmonar.

ABSTRACT

Objective : To evaluate the level of self-reported adherence to physical therapy recommendations in pediatric patients (6-17 years) with cystic fibrosis (CF) and to ascertain whether the different levels of adherence correlate with pulmonary function, clinical aspects, and quality of life. Methods : This was a cross-sectional study. The patients and their legal guardians completed a questionnaire regarding adherence to physical therapy recommendations and a CF quality of life questionnaire. We collected demographic, spirometric, and bacteriological data, as well as recording the frequency of hospitalizations and Shwachman-Kulczycki (S-K) clinical scores. Results : We included 66 patients in the study. Mean age, FEV1 (% of predicted), and BMI were 12.2 ± 3.2 years, 90 ± 24%, and 18.3 ± 2.5 kg/m2, respectively. The patients were divided into two groups: high-adherence (n = 39) and moderate/poor-adherence (n = 27). No statistically significant differences were found between the groups regarding age, gender, family income, and total S-K clinical scores. There were statistically significant differences between the high-adherence group and the moderate/poor-adherence group, the latter showing lower scores for the "radiological findings" domain of the S-K clinical score (p = 0.030), a greater number of hospitalizations (p = 0.004), and more days of hospitalization in the last year (p = 0.012), as well as lower scores for the quality of life questionnaire domains emotion (p = 0.002), physical (p = 0.019), treatment burden (p < 0.001), health perceptions (p = 0.036), social (p = 0.039), and respiratory (p = 0.048). Conclusions : Low self-reported adherence to physical therapy recommendations was associated with worse radiological findings, a greater number of hospitalizations, and decreased quality of life in pediatric CF patients.


Objetivo : Avaliar o grau de adesão autorrelatada às recomendações fisioterapêuticas em pacientes pediátricos (6-17 anos) com fibrose cística (FC) e determinar se os diferentes níveis de adesão se correlacionam com a função pulmonar, aspectos clínicos e qualidade de vida. Métodos : Estudo transversal no qual os pacientes e responsáveis responderam um questionário sobre a adesão à fisioterapia recomendada e um questionário da qualidade de vida em FC. Foram coletados dados demográficos, espirométricos e bacteriológicos, assim como a frequência de internações e resultados do escore clínico de Shwachman-Kulczycki (S-K). Resultados : Participaram 66 pacientes. As médias de idade, VEF1 (em % do previsto) e IMC foram, respectivamente, 12,2 ± 3,2 anos, 90 ± 24% e 18,3 ± 2,5 kg/m2. Os pacientes foram divididos em dois grupos: alta adesão (n = 39) e moderada/baixa adesão (n = 27). Não houve diferenças estatisticamente significativas para idade, sexo, renda familiar e escore clínico de S-K total na comparação dos dois grupos. Houve diferenças estatisticamente significativas entre os grupos alta adesão e moderada/baixa adesão, este último mostrando valores significativamente menores para o domínio "achados radiológicos" do escore clínico de S-K apresentou (p = 0,030), um maior número de hospitalizações (p = 0,004) e de dias de internação no último ano (p = 0,012), assim como menores escores para os seguintes domínios do questionário de qualidade de vida: emocional (p = 0,002), físico (p = 0,019), tratamento (p < 0,001), saúde (p = 0,036), social (p = 0,039) e respiratório (p = 0,048). Conclusões : A baixa adesão autorrelatada às recomendações fisioterapêuticas associou-se com piores achados radiológicos, maior número de hospitalizações e diminuição da qualidade de vida em pacientes pediátricos com FC.

ABSTRACT

Objective: Few studies have evaluated the variability of the perception of dyspnea in healthy subjects. The objective of this study was to evaluate the variability of the perception of dyspnea in healthy subjects during breathing against increasing inspiratory resistive loads, as well as to assess the association between the level of perception of dyspnea and the level of physical activity. Methods: This was a cross-sectional study involving healthy individuals 16 years of age or older. Subjects underwent inspiratory resistive loading testing, in which the level of perception of dyspnea was quantified with the modified Borg scale. We also determined body mass indices (BMIs), assessed maximal respiratory pressures, performed pulmonary function tests, applied the international physical activity questionnaire (IPAQ)-long form, and conducted six-minute walk tests (6MWTs). The level of perception of dyspnea was classified as low (Borg score < 2), intermediate (Borg score, 2-5), or high (Borg score > 5). Results: We included 48 healthy subjects in the study. Forty-two subjects completed the test up to a load of 46.7 cmH2O/L/s. The level of perception of dyspnea was classified as low, intermediate, and high in 13, 19, and 10 subjects, respectively. The level of perception of dyspnea was not significantly associated with age, gender, BMI, IPAQ-long form score, maximal respiratory pressures, or pulmonary function test results. Conclusions: The scores for perceived dyspnea induced by inspiratory resistive loading in healthy subjects presented wide variability. The perception of dyspnea was classified as low in 31% of the subjects, intermediate in 45%, and high in 24%. There was no association between the level of perception of dyspnea and the level of physical activity (IPAQ or six-minute walk distance). .


Objetivo: Poucos estudos avaliaram a variabilidade da percepção da dispneia em indivíduos saudáveis. O objetivo deste estudo foi avaliar a variabilidade da percepção da dispneia em indivíduos saudáveis através do uso de cargas resistivas inspiratórias crescentes, assim como avaliar a associação entre o nível de percepção da dispneia e o nível de atividade física. Métodos: Estudo transversal realizado em indivíduos saudáveis com idade ≥ 16 anos. Os indivíduos foram submetidos ao teste de cargas resistivas inspiratórias, no qual o nível de percepção da dispneia foi quantificado pela escala de Borg modificada. Foram também determinados os índices de massa corpórea (IMC), pressões respiratórias máximas, testes de função pulmonar, international physical activity questionnaire (IPAQ)-long form, e testes de caminhada de seis minutos (TC6). Os indivíduos foram classificados em percepção baixa (Borg < 2), intermediária (Borg, 2-5) e alta (Borg > 5). Resultados: Foram incluídos no estudo 48 indivíduos saudáveis. Desses, 42 completaram o teste até a carga de 46,7 cmH2O/l/s. O nível de percepção da dispneia foi classificado como baixo, intermediário e alto em 13, 19 e 10 indivíduos, respectivamente. Não houve associações significativas do nível de percepção da dispneia com idade, sexo, IMC, IPAQ e testes de função pulmonar. Conclusões: Os escores da percepção da dispneia induzida por cargas resistivas inspiratórias em indivíduos saudáveis apresentaram uma ampla variabilidade. A percepção da dispneia foi classificada como baixa, intermediária e alta em 31%, 45% e 24%, respectivamente. Não houve associações entre o nível de percepção da dispneia e o nível de atividade física (IPAQ ou distância no TC6). .

ABSTRACT

Although cystic fibrosis (CF) is an irreversible genetic disease, advances in treatment have increased the life expectancy of CF patients. Upper airway involvement, which is mainly due to pathological changes in the paranasal sinuses, is prevalent in CF patients, although many are only mildly symptomatic (with few symptoms). The objective of this literature review was to discuss the pathophysiology and current therapeutic management of chronic rhinosinusitis (CRS) in CF patients. The review was based on current evidence, which was classified in accordance with the Oxford Centre for Evidence-Based Medicine criteria. When symptomatic, CRS with nasal polyps can affect quality of life and can lead to pulmonary exacerbations, given that the paranasal sinuses can be colonized with pathogenic bacteria, especially Pseudomonas aeruginosa. Infection with P. aeruginosa plays a crucial role in morbidity and mortality after lung transplantation in CF patients. Although clinical treatment of the upper airways is recommended as initial management, this recommendation is often extrapolated from studies of CRS in the general population. When sinonasal disease is refractory to noninvasive therapy, surgery is indicated. Further studies are needed in order to gain a better understanding of upper airway involvement and improve the management of CRS in CF patients, with the objective of preserving lung function and avoiding unnecessary invasive procedures.


A fibrose cística (FC) é uma doença genética irreversível, mas os avanços no tratamento têm aumentado a expectativa de vida dos pacientes. O acometimento das vias aéreas superiores, principalmente por alterações patológicas dos seios paranasais, é prevalente nesses pacientes, embora muitos apresentem poucos sintomas. O objetivo desta revisão é discutir a fisiopatologia e o manejo terapêutico atual da rinossinusite crônica (RSC) na FC. A revisão fundamentou-se nas evidências mais recentes, classificadas em conformidade com os critérios do Oxford Centre for Evidence-Based Medicine. Quando sintomática, a RSC com pólipos nasais pode afetar a qualidade de vida e as exacerbações pulmonares, já que os seios paranasais podem ser colonizados por bactérias patogênicas, principalmente a Pseudomonas aeruginosa. Essa bactéria tem papel crucial na morbidade e mortalidade após o transplante pulmonar em pacientes com FC. Embora o tratamento clínico das vias aéreas superiores seja indicado no manejo inicial, a indicação é muitas vezes extrapolada de estudos sobre RSC na população geral. A cirurgia é a alternativa quando o quadro nasossinusal é refratário à terapia não invasiva. Mais estudos são necessários para compreender melhor o acometimento das vias aéreas superiores e melhorar o manejo da RSC na FC, a fim de preservar a função pulmonar e evitar procedimentos invasivos desnecessários.

ABSTRACT

Objective: Bedside lung ultrasound (LUS) is a noninvasive, readily available imaging modality that can complement clinical evaluation. The Bedside Lung Ultrasound in Emergency (BLUE) protocol has demonstrated a high diagnostic accuracy in patients with acute respiratory failure (ARF). Recently, bedside LUS has been added to the medical training program of our ICU. The aim of this study was to investigate the accuracy of LUS based on the BLUE protocol, when performed by physicians who are not ultrasound experts, to guide the diagnosis of ARF. Methods: Over a one-year period, all spontaneously breathing adult patients consecutively admitted to the ICU for ARF were prospectively included. After training, 4 non-ultrasound experts performed LUS within 20 minutes of patient admission. They were blinded to patient medical history. LUS diagnosis was compared with the final clinical diagnosis made by the ICU team before patients were discharged from the ICU (gold standard). Results: Thirty-seven patients were included in the analysis (mean age, 73.2 ± 14.7 years; APACHE II, 19.2 ± 7.3). LUS diagnosis had a good agreement with the final diagnosis in 84% of patients (overall kappa, 0.81). The most common etiologies for ARF were pneumonia (n = 17) and hemodynamic lung edema (n = 15). The sensitivity and specificity of LUS as measured against the final diagnosis were, respectively, 88% and 90% for pneumonia and 86% and 87% for hemodynamic lung edema. Conclusions: LUS based on the BLUE protocol was reproducible by physicians who are not ultrasound experts and accurate for the diagnosis of pneumonia and hemodynamic lung edema. .


Objetivo: O ultrassom pulmonar (USP) à beira do leito é uma técnica de imagem não invasiva e prontamente disponível que pode complementar a avaliação clínica. O protocolo Bedside Lung Ultrasound in Emergency (BLUE, ultrassom pulmonar à beira do leito em situações de emergência) demonstrou elevado rendimento diagnóstico em pacientes com insuficiência respiratória aguda (IRpA). Recentemente, um programa de treinamento em USP à beira do leito foi implementado na nossa UTI. O objetivo deste estudo foi avaliar a acurácia do USP baseado no protocolo BLUE, quando realizado por médicos com habilidades básicas em ultrassonografia, para orientar o diagnóstico de IRpA. Métodos: Ao longo de um ano, todos os pacientes adultos consecutivos respirando espontaneamente admitidos na UTI por IRpA foram prospectivamente inclusos. Após treinamento, 4 operadores com habilidades básicas em ultrassonografia realizaram o USP em até 20 minutos após a admissão na UTI, cegados para a história do paciente. Os diagnósticos do USP foram comparados aos diagnósticos da equipe assistente ao final da internação na UTI (padrão-ouro). Resultados: Foram inclusos na análise 37 pacientes (média etária: 73,2 ± 14,7 anos; APACHE II: 19,2 ± 7,3). O diagnóstico do USP demonstrou concordância com o diagnóstico final em 84% dos casos (kappa total: 0,81). As causas mais comuns de IRpA foram pneumonia (n = 17) e edema pulmonar cardiogênico (n = 15). A sensibilidade e a especificidade do USP comparado ao diagnóstico final foram de 88% e 90% para pneumonia e de 86% e 87% para edema pulmonar cardiogênico, respectivamente. Conclusões: O USP baseado no protocolo BLUE foi reproduzível por médicos com habilidades básicas em ultrassonografia e acurado para o diagnóstico de pneumonia e de edema pulmonar cardiogênico. .

ABSTRACT

Objective: To evaluate clinical characteristics and outcomes in patients hospitalized for tuberculosis, comparing those in whom tuberculosis treatment was started within the first 24 h after admission with those who did not. Methods: This was a retrospective cohort study involving new tuberculosis cases in patients aged ≥ 18 years who were hospitalized after seeking treatment in the emergency room. Results: We included 305 hospitalized patients, of whom 67 (22.0%) received tuberculosis treatment within the first 24 h after admission ( ≤24h group) and 238 (88.0%) did not (>24h group). Initiation of tuberculosis treatment within the first 24 h after admission was associated with being female (OR = 1.99; 95% CI: 1.06-3.74; p = 0.032) and with an AFB-positive spontaneous sputum smear (OR = 4.19; 95% CI: 1.94-9.00; p < 0.001). In the ≤24h and >24h groups, respectively, the ICU admission rate was 22.4% and 15.5% (p = 0.258); mechanical ventilation was used in 22.4% and 13.9% (p = 0.133); in-hospital mortality was 22.4% and 14.7% (p = 0.189); and a cure was achieved in 44.8% and 52.5% (p = 0.326). Conclusions: Although tuberculosis treatment was initiated promptly in a considerable proportion of the inpatients evaluated, the rates of in-hospital mortality, ICU admission, and mechanical ventilation use remained high. Strategies for the control of tuberculosis in primary care should consider that patients who seek medical attention at hospitals arrive too late and with advanced disease. It is therefore necessary to implement active surveillance measures in the community for earlier diagnosis and treatment. .


Objetivo: Comparar as características clínicas e os desfechos de pacientes hospitalizados por tuberculose que iniciaram tratamento nas primeiras 24 h de permanência hospitalar com as daqueles que iniciaram tratamento após 24 h. Métodos: Estudo de coorte retrospectivo de casos novos de tuberculose com idade ≥ 18 anos que necessitaram internação hospitalar após atendimento no setor de emergência. Resultados: Foram incluídos 305 pacientes hospitalizados, dos quais 67 (22,0%) iniciaram o tratamento nas primeiras 24 h (grupo ≤24h), e 238 (88,0%) o iniciaram após (grupo >24h). Ser do sexo feminino (OR = 1,99; IC95%: 1,06-3,74; p = 0,032) e ter pesquisa de BAAR positiva no escarro espontâneo (OR = 4,19; IC95%: 1,94-9,00; p < 0,001) se associaram com o tratamento nas primeiras 24 h. Na comparação dos grupos ≤24h e >24h, a taxa de internação em UTI foi de, respectivamente, 22,4% e 15,5% (p = 0,258), enquanto a ventilação mecânica foi utilizada em 22,4% e 13,9% (p = 0,133), a taxa de óbito hospitalar foi de 22,4% e 14,7% (p = 0,189), e a taxa de cura foi de 44,8% e 52,5% (p = 0,326). Conclusões: Embora o tratamento antituberculose tenha sido iniciado rapidamente em uma proporção considerável dos pacientes hospitalizados, as taxas de mortalidade hospitalar, internação em UTI e uso de ventilação mecânica permaneceram elevadas. Estratégias para o controle de tuberculose na atenção primária devem considerar que pacientes atendidos em hospitais chegam muito tardiamente e com doença avançada, sendo necessário implementar medidas de busca ativa na comunidade para o diagnóstico e o tratamento mais precoce. .
