Sim JK, Moon SJ, Choi J, Oh JY, Lee YS, Min KH, Hur GY, Lee SY, Shim JJ. Mechanical ventilation in patients with idiopathic pulmonary fibrosis in Korea: a nationwide cohort study. Korean J Intern Med 2024; 39:295-305. [PMID: 38326962 PMCID: PMC10918379 DOI: 10.3904/kjim.2023.273] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/26/2023] [Revised: 09/17/2023] [Accepted: 10/19/2023] [Indexed: 02/09/2024] Open
Abstract
BACKGROUND/AIMS The prognosis of patients with idiopathic pulmonary fibrosis (IPF) and respiratory failure requiring mechanical ventilation is poor. Therefore, mechanical ventilation is not recommended. Recently, outcomes of mechanical ventilation, including those for patients with IPF, have improved. The aim of this study was to investigate changes in the use of mechanical ventilation in patients with IPF and their outcomes over time. METHODS This retrospective, observational cohort study used data from the National Health Insurance Service database. Patients diagnosed with IPF between January 2011 and December 2019 who were placed on mechanical ventilation were included. We analyzed changes in the use of mechanical ventilation in patients with IPF and their mortality using the Cochran- Armitage trend test. RESULTS Between 2011 and 2019, 1,227 patients with IPF were placed on mechanical ventilation. The annual number of patients with IPF with and without mechanical ventilation increased over time. However, the ratio was relatively stable at approximately 3.5%. The overall hospital mortality rate was 69.4%. There was no improvement in annual hospital mortality rate. The overall 30-day mortality rate was 68.7%, which did not change significantly. The overall 90-day mortality rate was 85.3%. The annual 90-day mortality rate was decreased from 90.9% in 2011 to 83.1% in 2019 (p = 0.028). CONCLUSION Despite improvements in intensive care and ventilator management, the prognosis of patients with IPF receiving mechanical ventilation has not improved significantly.

Prognostic factors associated with mortality in acute exacerbations of idiopathic pulmonary fibrosis: A systematic review and meta-analysis. Respir Med 2024; 222:107515. [PMID: 38154738 DOI: 10.1016/j.rmed.2023.107515] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/19/2023] [Revised: 12/24/2023] [Accepted: 12/25/2023] [Indexed: 12/30/2023]
Abstract
BACKGROUND Acute exacerbations of idiopathic pulmonary fibrosis (AE-IPF) increases mortality risk, but which factors increase mortality is unknown. We aimed to perform a prognostic review of factors associated with mortality in patients with IPF. STUDY DESIGN and methods: We searched MEDLINE, EMBASE, and CINAHL for studies that reported on the association between any prognostic factor and AE-IPF. We assessed risk of bias using the QUIPS tool. We conduced pairwise meta-analyses using REML heterogeneity estimator, and GRADE approach to assess the certainty of the evidence. RESULTS We included 35 studies in our analysis. We found that long-term supplemental oxygen at baseline (aHR 2.52 [95 % CI 1.68 to 3.80]; moderate certainty) and a diagnosis of IPF compared to non-IPF ILD (aHR 2.19 [95 % CI 1.22 to 3.92]; moderate certainty) is associated with a higher risk of death in patients with AE-IPF. A diffuse pattern on high resolution computed tomography (HRCT) compared to a non-diffuse pattern (aHR 2.61 [95 % CI 1.32 to 2.90]; moderate certainty) is associated with a higher risk of death in patients with AE-IPF. We found that using corticosteroids prior to hospital admission (aHR 2.19 [95 % CI 1.26 to 3.82]; moderate certainty) and those with increased neutrophils (by % increase) in bronchoalveolar lavage (BAL) during the exacerbation is associated with a higher risk of death (aHR 1.02 [1.01 to 1.04]; moderate certainty). INTERPRETATION Our results have implications for healthcare providers in making treatment decisions and prognosticating the clinical trajectory of patients, for researchers to design future interventions to improve patient trajectory, and for guideline developers in making decisions about resource allocation.

COVID-19 in Patients with Pre-Existing Interstitial Lung Disease: Potential Value of a Steroid-Based Treatment Strategy. J Clin Med 2023; 12:4940. [PMID: 37568341 PMCID: PMC10419957 DOI: 10.3390/jcm12154940] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2023] [Revised: 07/23/2023] [Accepted: 07/25/2023] [Indexed: 08/13/2023] Open
Abstract
The prognosis of patients with coronavirus disease 2019 (COVID-19) and pre-existing interstitial lung disease (preILD) is poor, and no effective treatment strategy has been determined. The aim of this study was to assess the effectiveness of a steroid-based treatment strategy for patients with COVID-19 and preILD. We retrospectively reviewed the medical records of 610 consecutive patients with COVID-19 treated at our institution between 1 March 2020 and 30 October 2021 and identified 7 patients with preILD, all of whom were treated with corticosteroids and remdesivir. All the patients were men with a median age of 63 years. Three of four patients with severe disease required invasive positive-pressure ventilation (n = 2) or nasal high-flow therapy (n = 1). All three patients could be weaned from respiratory support; however, one died in hospital. The remaining patient with severe COVID-19 had a do-not-resuscitate order in place and died while hospitalized. All three patients with moderate COVID-19 were discharged. The 30-day mortality was 0%, and the mortality rate during the entire observation period was 28.5%. The prognosis of our patients with COVID-19 and preILD has been better than in previous reports. Our management strategy using corticosteroids may have improved these patients' prognosis.

Abstract
BACKGROUND Several markers have been identified to increase the risk for acute exacerbation of interstitial lung disease (AE-ILD) or mortality related to AE-ILD. However, less is known about the risk predictors of ILD patients who have survived AE. The aim of the study was to characterise AE-ILD survivors and investigate prognostic factors in this subpopulation. METHODS All AE-ILD patients (n = 95) who had been discharged alive from two hospitals located in Northern Finland were selected from a population of 128 AE-ILD patients. Clinical data related to the hospital treatment and six-month follow-up visit were collected retrospectively from medical records. RESULTS Fifty-three patients with idiopathic pulmonary fibrosis (IPF) and 42 patients with other ILD were identified. Two thirds of the patients had been treated without invasive or non-invasive ventilation support. The clinical features of six-month survivors (n = 65) and non-survivors (n = 30) did not differ in terms of medical treatment or oxygen requirements. Of the patients, 82.5% used corticosteroids at the six-month follow-up visit. Fifty-two patients experienced at least one non-elective respiratory re-hospitalisation before the six-month follow-up visit. In a univariate model, IPF diagnosis, high age and a non-elective respiratory re-hospitalisation increased the risk of death, although re-hospitalisation was the only independent risk factor in a multivariate model. In six-month survivors, there was no statistically significant decrease in pulmonary function test results (PFT) examined at the follow-up visit compared with earlier PFT examined near the time of AE-ILD. CONCLUSIONS The AE-ILD survivors were a heterogeneous group of patients both clinically and in terms of their outcome. A non-elective respiratory re-hospitalisation was identified as a marker of poor prognosis among AE-ILD survivors.

Impact of the revised definition on incidence and outcomes of acute exacerbation of idiopathic pulmonary fibrosis. Sci Rep 2022; 12:8817.

Abstract
The revised definition of acute exacerbation (AE) in idiopathic pulmonary fibrosis (IPF) was proposed in 2016, but changes in the incidence and impact on prognosis of the re-defined AE compared to those of the previous definition remain unclear. Clinical data of 445 patients with IPF (biopsy proven cases: 165) were retrospectively reviewed. The median follow-up period was 36.8 months and 17.5% (n = 78) experienced AE more than once. The 1- and 3-year incidence rates of AE were 6.7% and 16.6%, respectively, and idiopathic AE accounted for 82.1% of AE. Older age, lower diffusing capacity of the lung for carbon monoxide and 10% relative decline in forced vital capacity for 6 months were independently associated with AE. The in-hospital mortality rate following AE was 29.5%. In the multivariable analysis, AE was independently associated with poor prognosis in patients with IPF. Compared to the old definition, the revised definition relatively increased the incidence of AE by 20.4% and decreased the in-hospital mortality by 10.1%. Our results suggest that the revised definition affects approximately 20% increase in the incidences and 10% reduction in the in-hospital mortality of AE defined by the past definition.

Abstract
Background Accelerated nodulosis (ARN) is a rare variant of rheumatoid nodules (RNs) that is characterized by a rapid onset or the worsening of RNs. It generally develops at the fingers in patients with rheumatoid arthritis (RA) receiving methotrexate (MTX). Few case reports have described ARN at an extracutaneous location. Case presentation An elderly patient with long-standing RA was admitted to our hospital with acute respiratory failure. Computed tomography upon admission showed diffuse ground-glass opacities superimposed with subpleural reticular shadowing and honeycombing and multiple nodules in the lungs and liver. Despite the discontinuation of MTX and introduction of an immunosuppressive regimen with pulse methylprednisolone followed by a tapering dose of prednisolone and intravenous cyclophosphamide, the patient died due to the acute exacerbation (AE) of RA-related interstitial lung disease (ILD) following the parallel waxing and waning of a diffuse interstitial shadow and pulmonary and liver nodules. At autopsy, RNs were scattered throughout both lung fields in addition to extensive interstitial changes. RNs were also detected in the liver and kidneys. The foci of cryptococcosis were mainly identified in alveolar spaces. Based on the clinical and pathological findings, these nodules were most consistent with ARN because of acute increases in the size and number of previously detected pulmonary nodules. Conclusion The present case is noteworthy because ARN was concurrently detected in multiple internal organs and may be associated with the AE of RA-related ILD.

Abstract
BACKGROUND AND OBJECTIVE Despite the high mortality of acute exacerbations of interstitial lung disease (AE-ILD), there is minimal evidence to guide management decisions. We aimed to assess the feasibility and outcomes of a standardized management protocol for AE-ILD. METHODS We performed a retrospective cohort study of patients with AE-ILD admitted to hospital between January 2015 and August 2019. Patients were managed with a standardized protocol including chest computed tomography (CT) at diagnosis, pulse corticosteroid treatment, and a follow-up CT 7 days after corticosteroid pulse. The association between idiopathic pulmonary fibrosis (IPF) versus non-IPF diagnosis and transplant-free survival within 1-year of AE-ILD was assessed using adjusted Cox proportional hazards regression survival analysis. Associations with CT chest improvement 7 days after corticosteroid pulse were secondarily assessed. RESULTS 89 patients with AE-ILD were identified. 1-year transplant-free and overall survival were 20.2 and 51.7%, respectively. Protocol adherence to pulse corticosteroids was high (95.5%). A diagnosis of IPF was associated with higher risk of death or transplant at 1-year versus a non-IPF diagnosis [hazard ratio (HR) 2.23, 95% CI 1.19-4.17, p = 0.012]. There were no significant associations with 7-day CT improvement; however, CT improvement was associated with higher transplant-free survival (p = 0.02) and a lower risk of in-hospital mortality (χ2 = 7.06, p = 0.01) on unadjusted analysis. CONCLUSIONS IPF is associated with a higher risk of death or transplant at 1-year as compared to a non-IPF diagnosis in patients with AE-ILD managed using a standardized protocol. Improvement on CT chest 7 days after corticosteroid pulse is associated with better survival.

Abstract
Introduction: Idiopathic pulmonary fibrosis (IPF), the most common of the idiopathic interstitial pneumonias, is a disease with a poor prognosis, and a highly heterogeneous and unpredictable clinical course. While most patients experience a relatively slow clinical, functional and radiological deterioration, a significant minority develops episodes of acute respiratory worsening termed acute exacerbations of IPF (AE-IPF). AE-IPF cannot be predicted or prevented and precede approximately half of IPF-related deaths. An international working group has recently proposed new diagnostic criteria and definition of AE-IPF.Areas covered: Despite their clinical significance, the optimal treatment of AE-IPF remains undetermined. In this review, we discuss the huge unmet need for an improved understanding of AE-IPF, with emphasis on current and potential therapeutic strategies.Expert opinion: The recently revised definition and diagnostic criteria of AE-IPF will facilitate future research into the etiology, pathobiology and clinical management of these life-threatening events. Efforts should be made to identify patients at higher risk for AE-IPF and detect early signs of these events. Potential treatment options should be studied in randomized, controlled trials. To this end, the importance of international collaborations cannot be overemphasized.
