RESUMO

ABSTRACT Objective: To assess the relative frequency of incident cases of interstitial lung diseases (ILDs) in Brazil. Methods: This was a retrospective survey of new cases of ILD in six referral centers between January of 2013 and January of 2020. The diagnosis of ILD followed the criteria suggested by international bodies or was made through multidisciplinary discussion (MDD). The condition was characterized as unclassifiable ILD when there was no specific final diagnosis following MDD or when there was disagreement between clinical, radiological, or histological data. Results: The sample comprised 1,406 patients (mean age = 61 ± 14 years), and 764 (54%) were female. Of the 747 cases exposed to hypersensitivity pneumonitis (HP)-related antigens, 327 (44%) had a final diagnosis of HP. A family history of ILD was reported in 8% of cases. HRCT findings were indicative of fibrosis in 74% of cases, including honeycombing, in 21%. Relevant autoantibodies were detected in 33% of cases. Transbronchial biopsy was performed in 23% of patients, and surgical lung biopsy, in 17%. The final diagnoses were: connective tissue disease-associated ILD (in 27%), HP (in 23%), idiopathic pulmonary fibrosis (in 14%), unclassifiable ILD (in 10%), and sarcoidosis (in 6%). Diagnoses varied significantly among centers (c2 = 312.4; p < 0.001). Conclusions: Our findings show that connective tissue disease-associated ILD is the most common ILD in Brazil, followed by HP. These results highlight the need for close collaboration between pulmonologists and rheumatologists, the importance of detailed questioning of patients in regard with potential exposure to antigens, and the need for public health campaigns to stress the importance of avoiding such exposure.


RESUMO Objetivo: Avaliar a frequência relativa de casos incidentes de doenças pulmonares intersticiais (DPI) no Brasil. Métodos: Levantamento retrospectivo de casos novos de DPI em seis centros de referência entre janeiro de 2013 e janeiro de 2020. O diagnóstico de DPI seguiu os critérios sugeridos por órgãos internacionais ou foi feito por meio de discussão multidisciplinar (DMD). A condição foi caracterizada como DPI não classificável quando não houve um diagnóstico final específico após a DMD ou houve discordância entre dados clínicos, radiológicos ou histológicos. Resultados: A amostra foi composta por 1.406 pacientes (média de idade = 61 ± 14 anos), sendo 764 (54%) do sexo feminino. Dos 747 casos expostos a antígenos para pneumonite de hipersensibilidade (PH), 327 (44%) tiveram diagnóstico final de PH. Houve relato de história familiar de DPI em 8% dos casos. Os achados de TCAR foram indicativos de fibrose em 74% dos casos, incluindo faveolamento, em 21%. Autoanticorpos relevantes foram detectados em 33% dos casos. Biópsia transbrônquica foi realizada em 23% dos pacientes, e biópsia pulmonar cirúrgica, em 17%. Os diagnósticos finais foram: DPI associada à doença do tecido conjuntivo (em 27%), PH (em 23%), fibrose pulmonar idiopática (em 14%), DPI não classificável (em 10%) e sarcoidose (em 6%). Os diagnósticos variaram significativamente entre os centros (c2 = 312,4; p < 0,001). Conclusões: Nossos achados mostram que DPI associada à doença do tecido conjuntivo é a DPI mais comum no Brasil, seguida pela PH. Esses resultados destacam a necessidade de uma estreita colaboração entre pneumologistas e reumatologistas, a importância de fazer perguntas detalhadas aos pacientes a respeito da potencial exposição a antígenos e a necessidade de campanhas de saúde pública destinadas a enfatizar a importância de evitar essa exposição.

RESUMO

ABSTRACT Connective tissue disease-associated interstitial lung disease (CTD-ILD) represents a group of systemic autoimmune disorders characterized by immune-mediated organ dysfunction. Systemic sclerosis, rheumatoid arthritis, idiopathic inflammatory myositis, and Sjögren's syndrome are the most common CTDs that present with pulmonary involvement, as well as with interstitial pneumonia with autoimmune features. The frequency of CTD-ILD varies according to the type of CTD, but the overall incidence is 15%, causing an important impact on morbidity and mortality. The decision of which CTD patient should be investigated for ILD is unclear for many CTDs. Besides that, the clinical spectrum can range from asymptomatic findings on imaging to respiratory failure and death. A significant proportion of patients will present with a more severe and progressive disease, and, for those, immunosuppression with corticosteroids and cytotoxic medications are the mainstay of pharmacological treatment. In this review, we summarized the approach to diagnosis and treatment of CTD-ILD, highlighting recent advances in therapeutics for the various forms of CTD.


RESUMO Doença pulmonar intersticial associada à doença do tecido conjuntivo (DPI-DTC) representa um grupo de distúrbios autoimunes sistêmicos caracterizados por disfunção de órgãos imunomediada. Esclerose sistêmica, artrite reumatoide, miosite inflamatória idiopática e síndrome de Sjögren são as DTC mais comuns que apresentam acometimento pulmonar, bem como pneumonia intersticial com achados autoimunes. A frequência de DPI-DTC varia de acordo com o tipo de DTC, mas a incidência total é de 15%, causando um impacto importante na morbidade e mortalidade. A decisão sobre qual paciente com DTC deve ser investigado para DPI não é clara para muitas DTC. Além disso, o espectro clínico pode variar desde achados assintomáticos em exames de imagem até insuficiência respiratória e morte. Parte significativa dos pacientes apresentará doença mais grave e progressiva, e, para esses pacientes, imunossupressão com corticosteroides e medicamentos citotóxicos são a base do tratamento farmacológico. Nesta revisão, resumimos a abordagem do diagnóstico e tratamento de DPI-DTC, destacando os recentes avanços na terapêutica para as diversas formas de DTC.

RESUMO

Este trabalho tem como objetivo investigar a associação entreo o uso dos cigarros eletrônicos e doenças pulmonares em adolescentes. Foi realizada uma revisão sistemática na base de dados PubMed. Os termos Mesh incluídos na busca foram "Electronic Nicotine Delivery Systems" e "Lung Diseases" e sinônimos no título e abstract, com o filtro de idade "child: birth - 18 years", para buscar artigos relacionados ao uso de cigarros eletrônicos e doenças pulmonares em adolescentes. Os critérios de elegibilidade consistiram em: usuários adolescentes, exposição ao cigarro eletrônico e doença pulmonar como desfecho. Os artigos foram selecionados por uma revisão pareada de maneira independente, primeiramente com a leitura dos títulos e resumos, seguida da leitura integral dos artigos selecionados, os quais foram analisados pela ferramenta New Castle-Ottawa quanto sua qualidade, e receberam entre 5 e 7 estrelas. Os dados encontrados foram extraídos para a realização da metanálise. Inicialmente foram encontrados 61 artigos, sendo seis considerados elegíveis, todos transversais e com aplicação de questionários. Na metanálise foi encontrada uma associação significativa entre o uso de cigarro eletrônico e exacerbação de asma (OR ajustado 1,44; IC 95% 1,17­1,76). Não foram encontrados estudos que avaliassem a associação do cigarro eletrônico e outras doenças pulmonares, incluindo EVALI (E-cigarette or Vaping product use-Associated Lung Injury), em adolescentes. Na metanálise foi encontrada uma associação significativa entre exacerbações de asma e uso de cigarros eletrônicos em adolescentes com asma crônica e nos previamente hígidos.


This study aims to investigate the association between electronic cigarette use and lung disease in adolescents. A systematic review was conducted in PubMed. We used the MeSH terms "Electronic Nicotine Delivery Systems" and "Lung Diseases" as well as synonyms in the title and abstract, with the age filter "child: birth - 18 years" to search for articles related to electronic cigarette use and lung disease in adolescents. The eligibility criteria consisted of adolescent users and exposure to e-cigarettes that resulted in lung disease. The articles were selected by independent assessment, reading first the titles and abstracts, then the full text of the selected articles. The Newcastle-Ottawa Scale was used to assess study quality, and the included studies received between 5 and 7 stars. Finally, the data were extracted for meta-analysis. Initially, 61 articles were found and 6 were considered eligible, all of which were cross-sectional and applied questionnaires. The meta-analysis found a significant association between electronic cigarette use and asthma exacerbation (adjusted OR 1.44 95% CI 1.17 - 1.76). However, no studies evaluated the association with other lung diseases, including electronic cigarette or vaping product use-associated lung injury in adolescents. The metaanalysis revealed a significant association between e-cigarette use and asthma exacerbation among adolescents with chronic asthma, as well as among their previously healthy peers.

Introducción: La ecografía es una técnica de imagen no invasiva que permite explorar diferentes órganos de manera inmediata, constituye un instrumento de alto valor diagnóstico al alcance del profesional de la salud, y es utilizada en todas las especialidades médicas. En los últimos años, la evolución tecnológica ha permitido que los aparatos de ecografía sean más pequeños, portátiles, y con una alta resolución, tal es el caso de la ecografía clínica o ecografía a pie de cama. La ecografía del paciente crítico ha cambiado la práctica médica; específicamente la ecografía pulmonar se debe realizar en todos los pacientes con enfermedad pulmonar aguda. Objetivo: Aportar el conocimiento teórico necesario para promover el uso de la ecografía pulmonar en la evaluación del paciente crítico, y contribuir, mediante su aplicación, a la disminución del riesgo de exposición a las radiografías. Métodos: Se efectuó una revisión de la literatura médica actualizada sobre el papel de la ecografía pulmonar en la evaluación del paciente crítico, en el período de julio a diciembre de 2021. Se utilizaron los siguientes motores de búsqueda: SciELO, Medigraphic y Google Académico. Conclusiones: En el contexto actual, la ecografía pulmonar ha adquirido un papel protagónico, pues su uso facilita una evaluación frecuente y no invasiva del paciente crítico con afección pleuropulmonar. Su aplicación garantiza la disminución del riesgo de exposición a las radiografías.


Introduction: ultrasound is a non-invasive imaging technique that allows us to explore different organs immediately; it constitutes an instrument of high diagnostic value within the reach of health professionals and used in all medical specialties. In recent years, technological evolution has allowed ultrasound devices to be smaller, portable and with high resolution, such is the case of clinical ultrasound or bedside ultrasound. Bedside ultrasound in critically ill patients has changed medical practice; specifically, lung ultrasound should be performed in all patients with acute lung disease. Objective: to provide the necessary theoretical knowledge in order to promote the use of lung ultrasound in the evaluation of critically ill patients, as well as to contribute, through its application, to reduce the risk of exposure to radiographs. Methods: a review of the updated medical literature on the role of lung ultrasound in the evaluation of the critically ill patients was performed from July to December 2021. SciELO, Medigraphic and Google Scholar were the search engines used. Conclusions: lung ultrasound has acquired a leading role in the current context, since its use facilitates a non-invasive and common evaluation of the criticall ill patients with pleuropulmonary disease. Its application guarantees the reduction of the risk of exposure to X-rays.

RESUMO

Dermatomyositis, a common autoimmune disease in clinical practice, often involves muscles and lungs, and can be complicated by malignant tumors, and the lung involvement can be fatal. Therefore, early diagnosis and treatment of dermatomyositis is of great benefit for the reduction of muscle and lung injury, early recognition and management of malignant tumors, and improvement of prognosis and survival rate of patients. However, the heterogeneity and various clinical manifestations of dermatomyositis pose challenges to early diagnosis. This article describes risk factors for dermatomyositis complicated by rapidly progressive pulmonary interstitial fibrosis, dysphagia or malignant tumors, and proposes a mode of "rashes + nailfold capillary abnormalities + myositis antibodies" for the early diagnosis of dermatomyositis, early recognition of important visceral injury and tumors, and early management, in order to improve overall survival rate of patients.

RESUMO

Objective:To identify the prevalence of pulmonary micro nodule (PMN) in osteosarcoma, investigate radiologic features of progressive PMN, and provide evidence for early diagnosis of pulmonary metastasis of osteosarcoma.Methods:Electronic articles published in PubMed, EMBASE, Web of Science and the Cochrane Library databases between January 1, 2000, and September 1, 2022, were searched and critically evaluated. The authors independently reviewed the abstracts and extracted data on the prevalence of PMN in osteosarcoma and radiologic features of progressive PMN. Seven high quality studies were finally included in the meta-analysis with evidence level III.Results:The pooled prevalence of PMN in osteosarcoma was 36.0%, 95% CI (14.6%, 57.3%). The pooled progressive rate of PMN was 52.5%, 95% CI (37.7%, 67.2%). As for a specific PMN, it was more likely to progress which had a larger Dmax, HR=2.40, 95% CI (1.06, 5.42), P=0.035. No significant difference was found in number, component, and border. Conclusion:PMN is quite common in patients with osteosarcoma. About half of the patients suffered the progression of PMN, and it is related to several risk factors.

RESUMO

Objective:To explore the impact of clinical features, serological indicators, and pulmonary function test (PFT) on the prognosis of rheumatoid arthritis-associated interstitial lung disease (RA-ILD).Methods:Clinical data of RA-ILD patients who were diagnosed by HRCT and were followed up in Changhai Hospital or Yancheng First People's Hospital from 2011 to 2021 were collected Respiratory functional impairment of the patients was evaluated according to the changes of HRCT score and PFT, and the patients were divided into progressive group and stable group. COX survival analysis and ROC curve were used to determine the factors related to the progression of RA-ILD.Results:Finally 98 RA-ILD patients were included. The mean age of ILD onset was (62.9±12.1) years old, the median course of RA was 7.0 (1.0, 15.3)years, and the median follow-up time was 36.5 months (14.0, 79.5). There were 49 cases in the progressive group, and the clinical characteristics and laboratory tests of the two groups were compared. The results showed that: progressive time [(23(8.5,43.0)months vs 63(32.5,90.9) months, Z=-4.55, P=0.001)], HRCT score [(115(109,135) vs 111(105,116), Z=-2.70, P=0.007)], forced vital capacity(FVC) predicted [(70.1±15.7)% vs (80.8±19.7)%, t=2.12, P=0.039)], diffusing capacity of the lungs for CO(DLCO) predicted [(57.5±16.3)% vs (83.4±18.8)%, t=4.87, P=0.001)], male [(44.9% vs 18.4%, χ2=7.97, P=0.005)], UIP pattern [(36(73.5%) vs 9(18.4%), χ2=29.96, P<0.001)], RF>200 U/ml[(21(65.6%) vs 18(41.9%), χ2=4.15, P=0.042)], anti-CCP>75 U/ml [(42(91.3%) vs 35(71.4%), χ2=6.10, P=0.013], all had significantly different between the two groups. In multivariate analyses, UIP[ HR(95% CI)=3.25(1.62,6.50), P<0.001], anti-CCP antibody >75 U/ ml[ HR(95% CI)=3.85 (1.20,12.33), P=0.023] and smoking [ HR (95% CI): 5.74(1.10, 30.13), P=0.039] were significantly correlated with the progression of pulmonary fibrosis in RA-ILD patients. PFT was performed in only 44 patients with RA-ILD. The univariate analyses and ROC curve suggested that DLCO predicted [ HR (95% CI)=1.04 (1.02,1.06), P<0.001] was a significant risk factor for the progression of RA-ILD, and the area under curve (AUC) of DLCO was 0.845 [95% CI=(0.729,0.961)]. Conclusion:UIP pattern, high titer of anti-CCP antibody, smoking, and reduced DLCO predicted % may be potential predictors for poor prognosis of RA-ILD patients.

RESUMO

Objective:To investigate the correlation between cytokeratin 19 fragment(CYFRA21-1), modified ultrasound B-line and connective tissue disease associated with interstitial lung disease (CTD-ILD).Methods:The data of 112 patients with CTD hospitalized in the Department of Rheumatology and Immunology of the Second Hospital of Fujian Medical University from September 2019 to December 2021 were retrospectively collected. Sixty patients in the CTD-ILD group and 52 patients in the connective tissue disease without interstitial lung disease (CTD-noILD) group were included. The t-test and χ2 test were used to compare the demographic characteristics and tumor-associated antigens of the two groups of patients. Modified ultrasound score and HRCT Warrick score were evaluated by Pearson correlation analysis. In addition, the relationship between CYFRA21-1, modified ultrasound score and Warrick score were evaluated, and the diagnostic efficacy of CYFRA21-1 and modified ultrasound of CTD-ILD was evaluated and analyzed by binary logistic regression analysis. Results:Patients in the CTD-ILD group had higher CYFRA21-1 concentrations than the CTD-no-ILD group[5.74(4.25, 9.79) ng/ml vs. 2.79(2.21, 3.23) ng/ml, Z=45.94, P<0.001], patients in the CTD-ILD group had higher modified ultrasound scores than the CTD-no-ILD group [44.5(36.5, 60.0) vs. 5.0 (3.2, 6.8), P<0.001]. Modified ultrasound score was positively correlated with Warrick score ( r=0.93, P<0.001) and CYRFA21-1 was positively correlated with modified ultrasound score ( r=0.39, P=0.042). The sensitivity of CYFRA21-1 in determining CTD-ILD was 81.7% and the specificity was 92.3% [ AUC (95% CI)=0.88(0.81, 0.95), P<0.001], the sensitivity of modified ultrasound B-line to determine CTD-ILD was 96.4% and the specificity was 92.9% [ AUC (95% CI)=0.99 (0.97, 1.00), P<0.001]. History of smoking[ OR(95% CI)=9.26(1.11, 77.12), P=0.040] and elevated CYFRA21-1 concentration[ OR(95% CI)=19.40(4.89, 76.95), P<0.001] were risk factors for CTD-ILD. Conclusion:CYFRA21-1 is expected to be a serum marker indicating concomitant ILD in patients with CTD. Modified ultrasound B-line to determine concomitant ILD in CTD patients has good diagnostic utility and can reflect the severity of pulmonary fibrosis in CTD-ILD patients.

RESUMO

Objective:To analyze the Risk factors for rapid progression of inpatients with anti-melanoma differentiation associated gene5 (MDA5) antibody-positive dermamyositis (DM) complicated with interstitial lung disease (ILD), and construct a clinical predictive model.Methods:A total of 63 hospitalized patients with anti MDA5 positive DM combined with ILD (MDA5+ DM-ILD) from January 1, 2016 to May 30, 2022 at the Second Affiliated Hospital of the Air Force Military Medical University were included in the study. They were divided into a control group (DM-ILD) and an observation group (DM-RPPILD) based on whether they had rapidly progressing interstitial lung disease (RPILD). Retrospective collection and organization of clinical case data from patients were conducted, and binary logistic regression was used to summarize the risk factors of DM-RPILD. R software was used to construct a clinical prediction model for RPILD occurrence using training set data, and validation set data was used to verify the predictive ability of the model.Results:The proportion of patients with SpO 2<90% at the initial diagnosis of ILD, the titers of anti MDA5 antibodies, immunoglobulin M (IgM), serum ferritin (FER) levels, and positive rates of anti Ro52 antibodies in the observation group were higher than those in the control group, the lymphocyte (LYM) count level was lower than that of the control group (all P<0.05). Binary logistic regression analysis showed SpO 2<90% at the initial diagnosis of ILD, FER level, LYM count, and anti Ro52 antibody were the influencing factors for the occurrence of RPILD (all P<0.05). The area under the curve (AUC) of the training set prediction model for predicting resistance to MDA5+ DM-RPILD was 0.922(95% CI: 0.887-0.957), with a sensitivity of 95.7% and a specificity of 72.5%; In the validation set, the prediction model predicted an AUC of 0.939(95% CI: 0.904-0.974) for resistance to MDA5+ DM-RPILD, with a sensitivity of 90.0% and a specificity of 88.9%; The calibration curves of the training and validation sets indicated that the predictive model had good calibration ability. Conclusions:SpO 2<90% at the initial diagnosis of ILD, FER levels increase, LYM count levels decrease, and anti Ro52 antibody positivity are risk factors for RPILD. The constructed clinical model has good predictive ability and has certain guiding significance for clinical work.

Objective:To investigate the clinical efficacy of caspofungin combined with voriconazole in the treatment of older adult patients with pulmonary fungal infection and its effects on pulmonary function and inflammatory factors.Methods:A total of 100 patients with pulmonary fungal infection admitted to Hangzhou Ninth People's Hospital from January 2016 to December 2020 were included in this study. They were randomly assigned to undergo treatment with either voriconazole (control group, n = 50) or caspofungin combined with voriconazole (observation group, n = 50) for 14 consecutive days. Clinical efficacy and changes in pulmonary function and inflammatory factors after treatment relative to before treatment were determined in each group. Results:Total response rate in the observation group was significantly higher than that in the control group [90.00% (45/50) vs. 74.00% (37/50), χ2 = 4.33, P < 0.05). After treatment, forced vital capacity, forced expiratory volume in 1 second, and maximum expiratory flow rate in the observation group were (2.31 ± 0.77) L, (79.30 ± 6.72)%, (86.14 ± 7.27)%, respectively, which were significantly higher than (1.78 ± 0.74) L, (73.22 ± 6.56)%, (78.16 ± 7.09)% in the control group ( t = 3.50, 4.57, 5.55, all P < 0.05). Tumor necrosis factor α, interleukin-6, and procalcitonin levels in the observation group were (8.32 ± 1.41) ng/L, (35.19 ± 3.40) μg/L, (1.94 ± 0.78) ng/L, respectively, which were significantly lower than (10.15 ± 1.58) ng/L, (46.09 ± 3.64) μg/L, (2.43 ± 0.84) ng/L in the control group ( t = 6.11, 15.43, 3.02, all P < 0.05). The incidence of adverse reactions in the observation group was 4.0% (2/50), which was significantly lower than 18.0% (9/50) in the control group ( χ2 = 5.00, P < 0.05). Conclusion:Caspofungin combined with voriconazole for the treatment of pulmonary fungal infection in older adult patients can effectively improve pulmonary function, inhibit the inflammatory response, and have no obvious adverse reactions with accurate clinical efficacy.

RESUMO

Objective:To investigate the incidence of interstitial pneumonia (IP) and its risk factors in newly-diagnosed diffuse large B-cell lymphoma (DLBCL) after treatment of R-CHOP regimen (rituximab combined with cyclophosphamide + doxorubicin + vincristine + prednisone) and R-CDOP regimen (rituximab combined with cyclophosphamide + vincristine + liposomal doxorubicin + prednisone).Methods:The clinical data of 54 newly-diagnosed DLBCL patients who were admitted to the Central Hospital Affiliated to Shandong First Medical University from January 2015 to August 2020 were retrospectively analyzed, of which 25 cases were treated with R-CDOP regimen, and 29 cases were treated with R-CHOP regimen. The incidence of IP was compared in patients stratified according to different clinically factors, and the risk factors of IP were analyzed by multivariate logistic regression.Results:The patients with R-CDOP regimen [compared with R-CHOP regimen: 32.0% (8/25) vs. 3.4% (1/29)], normal lactate dehydrogenase level before treatment [compared with high level: 29.0% (9/31) vs. 0 (0/23)], eosinophilic count>0.1×10 9/L [compared with ≤0.1×10 9/L: 28.0% (7/25) vs. 6.9% (2/29)] and Ki-67 positive index<80% [compared with ≥80%: 23.1% (9/39) vs. 0 (0/15)] had a higher incidence of IP (all P<0.05), there were no statistical differences in the incidence of IP among patients stratified with age, gender, smoking history, underlying disease, stage, international prognostic index score, Eastern Cooperative Oncology Group score, type, B symptoms, β 2-microglobulin, and lymphocyte count (all P>0.05). Multivariate logistic regression analysis showed that the application of R-CDOP regimen was the independent risk factor for the incidence of IP (compared with R-CHOP regimen: OR = 2.898, 95% CI 1.358-6.176, P = 0.008). Conclusions:The application of chemotherapy with R-CDOP regimen in DLBCL patients increases the incidence risk of IP, which needs to be closely monitored and prevented during treatment.

RESUMO

ABSTRACT Many interstitial lung diseases (ILDs) share mechanisms that result in a progressive fibrosing phenotype. In Brazil, the most common progressive fibrosing interstitial lung diseases (PF-ILDs) are chronic hypersensitivity pneumonitis, idiopathic pulmonary fibrosis, unclassified ILD, and connective tissue diseases. PF-ILD is seen in approximately 30% of patients with ILD. Because PF-ILD is characterized by disease progression after initiation of appropriate treatment, a diagnosis of the disease resulting in fibrosis is critical. Different criteria have been proposed to define progressive disease, including worsening respiratory symptoms, lung function decline, and radiological evidence of disease progression. Although the time elapsed between diagnosis and progression varies, progression can occur at any time after diagnosis. Several factors indicate an increased risk of progression and death. In the last few years, antifibrotic drugs used in patients with idiopathic pulmonary fibrosis have been tested in patients with PF-ILD. The effects of nintedanib and placebo have been compared in patients with PF-ILD, a mean difference of 107.0 mL/year being observed, favoring nintedanib. The U.S. Food and Drug Administration and the Brazilian Health Regulatory Agency have approved the use of nintedanib in such patients on the basis of this finding. Pirfenidone has been evaluated in patients with unclassified ILD and in patients with other ILDs, the results being similar to those for nintedanib. More studies are needed in order to identify markers of increased risk of progression in patients with ILD and determine the likelihood of response to treatment with standard or new drugs.


RESUMO Muitas doenças pulmonares intersticiais (DPI) compartilham mecanismos que resultam em um fenótipo fibrosante progressivo. No Brasil, as doenças pulmonares intersticiais fibrosantes progressivas (DPI-FP) mais comuns são a pneumonite de hipersensibilidade crônica, a fibrose pulmonar idiopática, a DPI não classificada e as doenças do tecido conjuntivo. A DPI-FP é observada em aproximadamente 30% dos pacientes com DPI. Como a DPI-FP é caracterizada pela progressão da doença após o início do tratamento adequado, é fundamental diagnosticar a doença que resulta em fibrose. Diferentes critérios foram propostos para definir doença progressiva, incluindo piora dos sintomas respiratórios, declínio da função pulmonar e evidências radiológicas de progressão da doença. Embora o tempo decorrido entre o diagnóstico e a progressão varie, a progressão pode ocorrer a qualquer momento após o diagnóstico. Vários fatores indicam risco aumentado de progressão e morte. Nos últimos anos, antifibróticos usados em pacientes com fibrose pulmonar idiopática foram testados em pacientes com DPI-FP. Os efeitos do nintedanibe e placebo foram comparados em pacientes com DPI-FP, com diferença média de 107,0 mL/ano a favor do nintedanibe. A Food and Drug Administration (EUA) e a Agência Nacional de Vigilância Sanitária aprovaram o uso do nintedanibe em tais pacientes com base nesse achado. A pirfenidona foi avaliada em pacientes com DPI não classificada e em pacientes com outras DPI, e os resultados foram semelhantes aos do nintedanibe. Mais estudos são necessários para identificar marcadores de risco aumentado de progressão em pacientes com DPI e determinar a probabilidade de resposta ao tratamento com medicamentos-padrão ou novos.
