SUMMARY OBJECTIVE: The objective of this study was to evaluate the quality of life of patients with noncystic fibrosis bronchiectasis during a 1-year follow-up by using the EuroQol – 5 Dimensions – 3 Levels (EQ-5D-3L) questionnaire. METHODS: A cohort study was conducted with 100 patients with noncystic fibrosis bronchiectasis and followed up with face-to-face visits or by telephone contact every 3 months for 1 year. All patients were recruited from a single referral center for bronchiectasis. At the time of recruiting and at the end of 1 year, the EQ-5D-3L questionnaire was applied to evaluate the patients’ quality of life. Variables, such as exacerbation, emergency care, comorbidities, hemoptysis, colonization, and hospitalization, were assessed. RESULTS: Of the 100 patients, 99 completed the study and 72% were women. There were no marked limitations in the mobility and self-care domains during the follow-up. At the end of the follow-up, 32 patients were extremely anxious or depressed. The quality of life assessed by using EQ-5D-3L had an initial mean score of 0.545 and of 0.589 after 1 year, which was statistically significant (p=0.011). CONCLUSION: Patients with noncystic fibrosis bronchiectasis have a poor quality of life, and the EQ-5D-3L questionnaire may be a tool for monitoring patients with bronchiectasis.

SUMMARY OBJECTIVE: This study aims to analyze the risk factors for in-hospital mortality in a cohort of patients admitted to a newly adapted intensive care unit in a public hospital in Rio de Janeiro. METHODS: This was an observational, retrospective, and descriptive study. Data were obtained from electronic medical records. Coronavirus disease 2019 (COVID-19) was diagnosed by detecting viral ribonucleic acid using reverse transcription polymerase chain reaction. Factors associated with the risk/protection from death were determined using the odds ratio and adjusted odds ratio. RESULTS: Fifty-one patients were admitted to the hospital. The median age of the patients was 63 years, 60% were male patients, and 54% were white patients. Sixty-seven percent of the patients were diagnosed with COVID-19. Sepsis at admission increased the chance of in-hospital death by 21 times (adjusted odds ratio=21.06 [0.79–555.2]; p=0.06). The strongest risk factor for death was the development of septic shock during hospitalization (adjusted odds ratio=98.56 [2.75–352.5]; p=0.01), and one in four patients had multidrug-resistant bacteria. Mechanical ventilation, vasopressors, neuromuscular blockers, and sedatives were also the risk factors for in-hospital mortality. The in-hospital mortality rate was 41%, and the mortality rate of patients on mechanical ventilation was 60%. The diagnosis of COVID-19 was not statistically related to the adverse outcomes. CONCLUSIONS: In this cohort, the strongest risk factor for in-hospital death was the development of nosocomial septic shock. Healthcare-associated infections have a significant impact on mortality rates. Therefore, to have a better outcome, it is important to consider not only the availability of beds but also the way healthcare is delivered.

RESUMO A fibrose pulmonar idiopática (FPI) é uma forma de pneumopatia intersticial crônica fibrosante de causa desconhecida, que acomete preferencialmente homens idosos, com história atual ou pregressa de tabagismo. Mesmo sendo uma doença incomum, ela assume grande importância devido a sua gravidade e prognóstico reservado. Nas últimas décadas, diversas modalidades terapêuticas farmacológicas foram investigadas para o tratamento dessa doença, de tal modo que conceitos clássicos vêm sendo revisados. O objetivo destas diretrizes foi definir recomendações brasileiras baseadas em evidências em relação ao emprego de agentes farmacológicos no tratamento da FPI. Procurou-se fornecer orientações a questões de ordem prática, enfrentadas pelos clínicos no seu cotidiano. 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 corticosteroides, N-acetilcisteína, tratamento medicamentoso do refluxo gastroesofágico, inibidores dos receptores da endotelina, inibidores da fosfodiesterase-5, pirfenidona e nintedanibe. Para a formulação das perguntas PICO, um grupo de especialistas brasileiros atuantes na área foi reunido, sendo realizada uma extensa revisão bibliográfica sobre o tema. As revisões sistemáticas com meta-análises previamente publicadas foram analisadas quanto à força das evidências compiladas e, a partir daí, foram concebidas recomendações seguindo a metodologia Grading of Recommendations Assessment, Development and Evaluation. Os autores acreditam que o presente documento represente um importante avanço a ser incorporado na abordagem de pacientes com FPI, objetivando principalmente favorecer seu manejo, e pode se tornar uma ferramenta auxiliar na definição de políticas públicas relacionadas à FPI.

ABSTRACT Idiopathic pulmonary fibrosis (IPF) is a form of chronic interstitial lung disease of unknown cause, which predominantly affects elderly men who are current or former smokers. Even though it is an uncommon disease, it is of great importance because of its severity and poor prognosis. In recent decades, several pharmacological treatment modalities have been investigated for the treatment of this disease, and the classic concepts have therefore been revised. The purpose of these guidelines was to define evidence-based recommendations regarding the use of pharmacological agents in the treatment of IPF in Brazil. We sought to provide guidance on the practical issues faced by clinicians in their daily lives. Patients of interest, Intervention to be studied, Comparison of intervention and Outcome of interest (PICO)-style questions were formulated to address aspects related to the use of corticosteroids, N-acetylcysteine, gastroesophageal reflux medications, endothelin-receptor antagonists, phosphodiesterase-5 inhibitors, pirfenidone, and nintedanib. To formulate the PICO questions, a group of Brazilian specialists working in the area was assembled and an extensive review of the literature on the subject was carried out. Previously published systematic reviews with meta-analyses were analyzed for the strength of the compiled evidence, and, on that basis, recommendations were developed by employing the Grading of Recommendations Assessment, Development and Evaluation approach. The authors believe that the present document represents an important advance to be incorporated in the approach to patients with IPF, aiming mainly to improve its management, and can become an auxiliary tool for defining public policies related to IPF.

RESUMO Objetivo: Analisar os sintomas em diferentes momentos do dia em pacientes com DPOC. Métodos: Estudo observacional multicêntrico de corte transversal em oito centros brasileiros. Foram avaliados os sintomas matinais, diurnos e noturnos em pacientes com DPOC estável. Resultados: Foram incluídos 593 pacientes em tratamento regular, sendo 309 (52,1%) do sexo masculino e 92 (15,5%) fumantes ativos. A média de idade foi de 67,7 anos, e a média de VEF1 foi de 49,4% do valor previsto. Os pacientes com sintomas mais graves (n = 183; 30,8%), em comparação com aqueles com sintomas leves e moderados, apresentaram pior nível de atividade física (p = 0,002), maior limitação ao fluxo aéreo (p < 0,001), exacerbações ambulatoriais (p = 0,002) e hospitalares (p = 0,043) mais frequentemente e piores resultados em instrumentos específicos. Os sintomas matinais e noturnos mais frequentes foram dispneia (em 45,2% e 33,1%, respectivamente), tosse (em 37,5% e 33,3%, respectivamente) e chiado (em 24,4% e 27,0%, respectivamente). Houve forte correlação da intensidade dos sintomas diurnos com sintomas matinais (r = 0,65, p < 0,001), sintomas noturnos (r = 0,60, p < 0,001), bem como com o escore do COPD Assessment Test (r = 0,62; p < 0,001); porém, houve uma correlação fraca com VEF1 (r = −0,205; p < 0,001). Conclusões: A dispneia foi mais frequente no período matinal do que no período noturno. Ter sintomas matinais e/ou noturnos foi associado à pior gravidade dos sintomas diurnos. A intensidade dos sintomas foi fortemente associada a pior qualidade de vida e frequência de exacerbações, mas fracamente associada à limitação ao fluxo aéreo.

ABSTRACT Objective: To analyze symptoms at different times of day in patients with COPD. Methods: This was a multicenter, cross-sectional observational study conducted at eight centers in Brazil. We evaluated morning, daytime, and nighttime symptoms in patients with stable COPD. Results: We included 593 patients under regular treatment, of whom 309 (52.1%) were male and 92 (15.5%) were active smokers. The mean age was 67.7 years, and the mean FEV1 was 49.4% of the predicted value. In comparison with the patients who had mild or moderate symptoms, the 183 (30.8%) with severe symptoms were less physically active (p = 0.002), had greater airflow limitation (p < 0.001), had more outpatient exacerbations (p = 0.002) and more inpatient exacerbations (p = 0.043), as well as scoring worse on specific instruments. The most common morning and nighttime symptoms were dyspnea (in 45.2% and 33.1%, respectively), cough (in 37.5% and 33.3%, respectively), and wheezing (in 24.4% and 27.0%, respectively). The intensity of daytime symptoms correlated strongly with that of morning symptoms (r = 0.65, p < 0.001) and that of nighttime symptoms (r = 0.60, p < 0.001), as well as with the COPD Assessment Test score (r = 0.62; p < 0.001), although it showed only a weak correlation with FEV1 (r = −0.205; p < 0.001). Conclusions: Dyspnea was more common in the morning than at night. Having morning or nighttime symptoms was associated with greater daytime symptom severity. Symptom intensity was strongly associated with poor quality of life and with the frequency of exacerbations, although it was weakly associated with airflow limitation.

Resumo A esclerose sistêmica (ES) é uma doença autoimune crônica de alta morbimortalidade. Ainda que a ciclofosfamida seja eficaz, para casos graves e refratários há demanda para novos tratamentos. A terapia biológica com depleção de células B com rituximabe (RTX) demonstrou eficácia para tal demanda em estudos abertos. Objetivo Avaliar retrospectivamente todos os pacientes que fizeram uso do RTX para tratamento de ES em nosso centro. Pacientes e métodos Foram avaliados retrospectivamente todos os prontuários de pacientes com ES que fizeram uso de RTX para tratamento da ES de janeiro de 2009 a janeiro de 2015. Dados de acometimento sistêmico, cutâneo, pulmonar e laboratoriais antes e seis meses após a primeira infusão de RTX foram coletados. Resultados Dez pacientes receberam o tratamento no período de estudo e foram incluídos na presente série de casos. Todos os pacientes tinham a forma difusa da doença. Cinco pacientes tinham formas iniciais (tempo de doença menor ou igual a quatro anos) e rapidamente progressiva da doença e cinco receberam o RTX em fases tardias da doença. Houve estabilização do quadro pulmonar em ambos os grupos de pacientes e redução no escore cutâneo nos pacientes com formas iniciais da doença. Discussão Similar ao encontrado em estudos prévios, o RTX foi eficaz no tratamento de formas iniciais e rapidamente progressivas da ES. Verificamos também benefício em pacientes com longa duração da doença.

Abstract Systemic sclerosis (SSc) is a chronic autoimmune disease with a high morbidity and mortality. Although cyclophosphamide is effective for severe and refractory cases, there is demand for new treatments. The biological treatment with B-cell depletion with rituximab (RTX) has demonstrated efficacy for this demand in open-label studies. Objective This study was conducted with the aim to retrospectively evaluate all patients who used RTX for the treatment of SSc in our center. Patients and methods We retrospectively evaluated medical records of all patients with SSc who used RTX to treat this disease from January 2009 to January 2015. Systemic, cutaneous, and pulmonary involvement data and laboratory results before and six months after the first infusion of RTX were collected. Results Ten patients received treatment during the study period and were included in this series. All patients had a diffuse form of the disease. Five patients suffered from an early (duration of disease shorter or equal to four years), rapidly progressive disease, and another five received RTX at late stages of the disease. In both groups of patients, stabilization of the pulmonary picture was observed, with a fall in the skin score in those patients with early forms of the disease. Discussion Similar to findings in previous studies, RTX was effective in treating early and rapidly progressive forms of SSc. We also found that patients with long-term illness may benefit from the treatment.
