Background Fibrotic hypersensitivity pneumonitis (fHP) is an immune-mediated interstitial lung disease caused by sensitisation to chronic allergen inhalation. This study aimed to determine prognostic indicators of progression and mortality in fHP. Methods This was a retrospective, multicentre, observational, cross-sectional cohort study of consecutive patients diagnosed with fHP from 1 January 2012 to 31 December 2021. Multivariate Cox regression analyses were used to calculate hazard ratios (HRs) with 95% confidence intervals for predictors of progression and survival. Results A total of 403 patients were diagnosed with fHP: median (interquartile range) age 66.5 (14.0) years, 51.9% females and 55.1% never-smokers. The cause of fHP was mainly fungal (39.7%) or avian (41.4%). Lung biopsy was performed in 269 cases (66.7%). In the whole cohort the variables that were related to mortality or lung transplant were older age (HR 1.08; p

Abstract Background Idiopathic pulmonary fibrosis (IPF) is a progressive disease associated with decline in lung function and poor prognosis entailing significant impairment in quality of life and high socioeconomic burden. The aim of this study was to characterize clinical management and resources utilization of patients with IPF in Spain, according to predicted forced vital capacity (FVC) % at baseline. Methods Prospective, non-interventional, multicentric real-world data study in patients with IPF in Spain with 12-months follow-up. Clinical management and resources utilization during study period were recorded and compared between groups. FVC decline and acute exacerbations occurrence and associated healthcare resource use were also analysed. FVC decline after 12 months was estimated as relative change. Results 204 consecutive patients with IPF were included and divided according to baseline FVC % predicted value. At baseline, patients with FVC 10% in the more preserved lung function groups than in the FVC

Abstract Rheumatoid arthritis (RA) is a systemic autoimmune disease whose main extra-articular organ affected is the lung, sometimes in the form of diffuse interstitial lung disease (ILD) and conditions the prognosis. A multicenter, observational, descriptive and cross-sectional study of consecutive patients diagnosed with RA-ILD. Demographic, analytical, respiratory functional and evolution characteristics were analyzed to evaluate the predictors of progression and mortality. 106 patients were included. The multivariate analysis showed that the diagnostic delay was an independent predictor of mortality (HR 1.11, CI 1.01–1.23, p = 0.035). Also, age (HR 1.33, 95% CI 1.09–1.62, p = 0.0045), DLCO (%) (HR 0.85, 95% CI 0.73–0.98, p = 0.0246), and final SatO2 (%) in the 6MWT (HR 0.62, 95% CI 0.39–0.99, p = 0.0465) were independent predictor variables of mortality, as well as GAP index (HR 4.65, 95% CI 1.59–13.54, p = 0.0051) and CPI index (HR 1.12, 95% CI 1.03–1.22, p = 0.0092). The withdrawal of MTX or LFN after ILD diagnosis was associated with disease progression in the COX analysis (HR 2.18, 95% CI 1.14–4.18, p = 0.019). This is the first study that highlights the diagnostic delay in RA-ILD is associated with an increased mortality just like happens in IPF.

Though idiopathic pulmonary fibrosis (IPF) is characterized by single-organ involvement, many comorbid conditions occur within other organ systems. Patients with IPF may present during evolution different complications and comorbidities that influence the prognosis and modify the natural course of their disease. In this chapter, we highlight common comorbid conditions encountered in IPF, discuss disease-specific diagnostic modalities, and review the current treatment data for several key comorbidities. The diagnosis and treatment of these comorbidities is a challenge for the pulmonologist specialized in interstitial lung diseases (ILDs). We will focus on pulmonary emphysema, lung cancer, gastroesophageal reflux, pulmonary hypertension, obstructive sleep apnea (sleep disorders), and acute exacerbation of IPF.

Resumen: Objetivo: El objetivo de este estudio fue analizar el proceso diagnóstico de los pacientes con fibrosis pulmonar idiopática en España, desde el inicio de los síntomas hasta el diagnóstico y tratamiento antifibrótico, en relación con la publicación de las sucesivas guías de práctica clínica. Material y métodos: Estudio multicéntrico, observacional, ambispectivo, en el que se analizaron los pacientes incluidos en el registro de la fibrosis pulmonar idiopática de la Sociedad Española de Neumología y Cirugía Torácica. Para ello se habilitó un cuaderno electrónico de recogida de datos en la web de la sociedad. Se recogieron variables sociodemográficas y clínicas al diagnóstico y seguimiento de los pacientes. Resultados: Desde enero de 2012 hasta diciembre de 2019 se incluyeron 1.064 pacientes, siendo finalmente analizados 929. El proceso diagnóstico varió en función del año en el que se realizó el diagnóstico y el patrón radiológico observado en la tomografía computarizada de alta resolución. En 244 (26,3%) pacientes, el diagnóstico se realizó con tomografía computarizada de alta resolución de tórax y evaluación clínica. La biopsia quirúrgica se utilizó hasta en el 50,2% de los casos diagnosticados antes del 2011, y en un 14,2% a partir de 2018. La mediana de tiempo que transcurre desde el inicio de los síntomas hasta el diagnóstico es de 360 días (RIC 120-720), siendo mayor de 2 años en el 21,0% de los pacientes. Recibieron tratamiento antifibrótico al 79,4% de los pacientes. El tiempo desde el diagnóstico hasta el inicio del tratamiento fue de 309 ± 596,5 días, con una mediana de 49 (RIC 0-307). Conclusiones: El proceso diagnóstico, incluyendo el tiempo hasta el diagnóstico y el tipo de pruebas utilizadas, ha ido cambiando desde 2011 hasta 2019, probablemente debido el avance en la investigación clínica y la publicación de guías consenso diagnóstico-terapéuticas. Abstract: Objective: The objective of the study was to analyze the diagnostic process and the time until the start of treatment of patients with idiopathic pulmonary fibrosis in relation to the publication of successive clinical practice guide. Material and methods: Multicenter, observational, ambispective study, in which patients includes in the idiopathic pulmonary fibrosis registry of the Spanish Society of Pulmonologist and Thoracic Surgery were analyzed. An electronic data collection notebook was enabled on the society's website. Sociodemographic and clinical variables were collected at diagnosis and follow-up of the patients. Results: From January 2012 to december 2019, 1064 patients were included in the registry, with 929 finally analyzed. The diagnosis process varied depending on the year in which it was performed, and the radiological pattern observed in the high-resolution computed tomography. Up to 26.3% of the cases (244) were diagnosed with chest high-resolution computed tomography and clinical evaluation. Surgical biopsy was used up to 50.2% of cases diagnosed before 2011, while it has been used in 14.2% since 2018. The median time from the onset of symptoms to diagnosis was 360 days (IQR 120-720), taking more than 2 years in the 21.0% of patients. A percentage of 79.4 of patients received antifibrotic treatment. The average time from diagnosis to the antifibrotic treatment has been 309 ± 596.5 days, with a median of 49 (IQR 0-307). Conclusions: The diagnostic process, including the time until diagnosis and the type of test used, has changed from 2011 to 2019, probably due to advances in clinical research and the publication of diagnostic-therapeutic consensus guidelines.
