Project description:BackgroundAcute exacerbations of interstitial lung diseases (AE-ILD) have a high mortality rate with no effective medical therapies. Lung transplantation is a potentially life-saving option for patients with AE-ILD, but its role is not well established. The aim of this study is to determine if this therapy during AE-ILD significantly affects post-transplant outcomes in comparison to those transplanted with stable disease.MethodsWe conducted a retrospective study of consecutive patients with AE-ILD admitted to our institution from 2015 to 2018. The comparison group included patients with stable ILD listed for lung transplant during the same period. The primary end-points were in-hospital mortality for patients admitted with AE-ILD and 1-year survival for the transplanted patients.ResultsOf 53 patients admitted for AE-ILD, 28 were treated with medical therapy alone and 25 underwent transplantation. All patients with AE-ILD who underwent transplantation survived to hospital discharge, whereas only 43% of the AE-ILD medically treated did. During the same period, 67 patients with stable ILD underwent transplantation. Survival at 1 year for the transplanted patients was not different for the AE-ILD group versus stable ILD group (96% vs 92.5%). The rates of primary graft dysfunction, post-transplant hospital length-of-stay and acute cellular rejection were similar between the groups.ConclusionPatients with ILD transplanted during AE-ILD had no meaningful difference in overall survival, rate of primary graft dysfunction or acute rejection compared with those transplanted with stable disease. Our results suggest that lung transplantation can be considered as a therapeutic option for selected patients with AE-ILD.

Project description:The increasing incidence of life-threatening Pneumocystis pneumonia (PCP) in non-HIV immunocompromised patients is a global concern. Yet, no reports have examined the prognostic significance of pre-existing interstitial lung disease (ILD) in non-HIV PCP. We retrospectively reviewed the medical records of non-HIV PCP patients with (ILD group) or without (non-ILD group) pre-existing ILD. The clinical features and outcomes of the ILD group were compared with those of the non-ILD group. Cox regression models were constructed to identify prognostic factors. 74 patients were enrolled in this study. The 90-day mortality was significantly higher in the ILD group than in the non-ILD group (62.5% versus 19.0%, p<0.001). In the ILD group, patients with a higher percentage of bronchoalveolar lavage fluid neutrophils had worse outcomes compared to those having a lower percentage (p=0.026). Multivariate analyses revealed that pre-existing ILD (p=0.002) and low levels of serum albumin (p=0.009) were independent risk factors for 90-day mortality. Serum levels of β-d-glucan were significantly reduced after treatment of PCP in both groups, whereas levels of Krebs von den Lungen-6 (KL-6) significantly increased in the ILD group. In the ILD group, the 90-day mortality of patients with increasing KL-6 levels after treatment was significantly higher than those with decreasing levels (78.9% versus 0%, p=0.019). In non-HIV PCP patients, pre-existing ILD is associated with a poorer prognosis. Prophylaxis for PCP is needed in patients with pre-existing ILD under immunosuppression.

Project description:BackgroundAcute exacerbation of interstitial lung disease often causes fatal respiratory deterioration in lung cancer patients with interstitial lung disease. Here, we examined whether the maximum standardized uptake value of a contralateral interstitial lesion was a predictive factor of acute exacerbation of interstitial lung disease within 30 days postoperatively in lung cancer patients with interstitial lung disease who underwent pulmonary resection.MethodsOverall, 117 consecutive lung cancer patients with interstitial lung disease who underwent pulmonary resection between August 2010 and April 2019 at the Kumamoto University Hospital were retrospectively analysed for the association between the maximum standardized uptake value of the contralateral interstitial lesions and interstitial lung disease parameters.ResultsThe median maximum standardized uptake value of contralateral interstitial lesions was 1.61, which was regarded as the cut-off point predictive of the incidence of acute exacerbation of interstitial lung disease. Eight patients developed postoperative acute exacerbation of interstitial lung disease. There was no significant association between the maximum standardized uptake value of the contralateral interstitial lesions and postoperative acute exacerbation of interstitial lung disease. The maximum standardized uptake value was weakly but significantly associated with lactate dehydrogenase levels (r=0.211, P=0.022), Krebs von den Lungen-6 (r=0.208, P=0.028), and % diffusing capacity for carbon monoxide (r=-0.290, P=0.002). Moreover, seven patients developed acute exacerbation of the interstitial lung disease during the clinical course after 30 postoperative days, and the incidence rate of acute exacerbation of interstitial lung disease was significantly higher in the high maximum standardized uptake value group (≥1.61) than in the low maximum standardised uptake value group (<1.61) (12.7% vs. 0%, P=0.002, Gray's test).ConclusionsMaximum standardized uptake value was not a predictor of postoperative acute exacerbation of interstitial lung disease in lung cancer patients with interstitial lung disease after pulmonary resection, but could be a predictive tool of an association with interstitial lung disease severity and activity markers.

Project description:BackgroundApproximately 50% of patients with interstitial lung disease (ILD) experience frailty, which remains unexplored in acute exacerbations of ILD (AE-ILD). A better understanding may help with prognostication and resource planning. We evaluated the association of frailty with clinical characteristics, physical function, hospital outcomes, and post-AE-ILD recovery.MethodsRetrospective cohort study of AE-ILD patients (01/2015-10/2019) with frailty (proportion ≥0.25) on a 30-item cumulative-deficits index. Frail and non-frail patients were compared for pre- and post-hospitalization clinical characteristics, adjusted for age, sex, and ILD diagnosis. One-year mortality, considering transplantation as a competing risk, was analysed adjusting for age, frailty, and Charlson Comorbidity Index (CCI).Results89 AE-ILD patients were admitted (median: 67 years, 63% idiopathic pulmonary fibrosis). 31 were frail, which was associated with older age, greater CCI, lower 6-min walk distance, and decreased independence pre-hospitalization. Frail patients had more major complications (32% vs 10%, p = .01) and required more multidisciplinary support during hospitalization. Frailty was not associated with 1-year mortality (HR: 0.97, 95%CI: [0.45-2.10]) factoring transplantation as a competing risk.ConclusionsFrailty was associated with reduced exercise capacity, increased comorbidities and hospital complications. Identifying frailty may highlight those requiring additional multidisciplinary support, but further study is needed to explore whether frailty is modifiable with AE-ILD.

Project description:Introduction: Data on the efficacy and risk of curative-intent chemoradiotherapy in patients with inoperable stage III non-small-cell lung cancer (NSCLC) and interstitial lung disease (ILD) are limited. The aim of this study was to explore the impact of ILD classification on acute exacerbation (AE) of ILD and prognosis in patients with stage III NSCLC and ILD treated with chemoradiotherapy. Materials and methods: We retrospectively reviewed the medical records of patients with stage III NSCLC and ILD treated with curative-intent chemoradiotherapy as the first-line treatment at the Shizuoka Cancer Center between June 2009 and May 2014. Results: Of 37 patients, 17 (46%) developed AE of ILD worse than grade 3 within 1 year after the last irradiation. In univariate analysis, the incidence rate of AE of ILD was lower in patients with a non-usual interstitial pneumonia (UIP) pattern than in those with a UIP pattern. Multivariate analysis showed that ILD classification was significantly associated with the incidence of AE of ILD. The median overall survival (OS) durations in patients with a non-UIP pattern and a UIP pattern were 16.5 and 9.3 months, respectively. In univariate analysis, patients with a non-UIP pattern showed better survival. Multivariate analysis showed that ILD classification was a significant independent prognostic factor. Conclusion: The incidence of AE of ILD was high in patients with stage III NSCLC and ILD treated with chemoradiotherapy as the first-line treatment. However, diagnosis of a non-UIP pattern could predict lower risk of AE of ILD and longer OS durations.

Project description:BackgroundFirst-generation epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) sometimes causes lung injury, thereby affecting survival. Although pre-existing interstitial lung abnormal shadow (pre-ILS) increases the risk of lung injury by EGFR-TKIs, its impact on osimertinib, a third-generation EGFR-TKI, remains unknown.Patients and methodsThis retrospective cohort study consecutively enrolled patients of EGFR-mutated non-small cell lung cancer treated with osimertinib. Computed tomography images were obtained and evaluated independently by three pulmonologists in a blinded manner. Factors associated with lung injury were assessed using a logistic regression model. Survival curves were calculated by the Kaplan-Meier method and compared using a log-rank test.ResultsOf the 195 patients, 40 had pre-ILS, and 21 (8 with and 13 without pre-ILS) developed lung injury during the observation period. Multivariate analysis revealed that pre-ILS was independently associated with lung injury (odds ratio, 3.1; 95% confidence interval [CI], 1.1-8.2; p = 0.025). Severe (≥Grade 3) lung injury was observed in eight (4.1%) patients, of whom, two (5%) and six (3.9%) had and did not have pre-ILS (p = 0.67), respectively. Grade 5 lung injury was not observed, and survival curves were similar between the patients who developed lung injury and those who did not (median 11 vs. 12 months; hazard ratio, 1.2; 95% CI, 0.56-2.7; p = 0.60).ConclusionsPre-ILS increased the risk of lung injury in patients of non-small cell lung cancer treated with osimertinib, while the severity of lung injury was not clearly affected by the presence of pre-ILS.

Project description:This study assessed whether perioperative management is associated with postoperative acute exacerbations (AEs) in interstitial lung disease (ILD) patients. Using secondary data from the study “Postoperative acute exacerbation of interstitial lung disease: a case–control study,” we compared the perioperative clinical management of the AE and non-AE groups (1:4 case–control matching) selected by sex, year of surgery (2009–2011, 2012–2014, and 2015–2017), and multiple surgeries within 30 days. We compared 27 and 108 patients with and without AEs, respectively. Rates of one lung ventilation (OLV) cases (70 vs. 29%; OR, 5.9; 95%CI, 2.34–14.88; p < 0.001) and intraoperative steroid administration (48 vs. 26%; OR, 2.65; 95%CI, 1.11–6.33; p = 0.028), and average mean inspiratory pressure (9.2 [1.8] vs. 8.3 [1.7] cmH2O; OR, 1.36; 95%CI, 1.04–1.79; p = 0.026), were significantly higher in the AE group. There was a significant difference in OLV between the groups (OR, 4.99; 95%CI, 1.90–13.06; p = 0.001). However, the fraction of inspired oxygen > 0.8 lasting > 1 min (63 vs. 73%, p = 0.296) was not significantly different between the groups. OLV was significantly associated with postoperative AEs in patients with ILD undergoing both pulmonary and non-pulmonary surgeries. Thus, preoperative risk considerations are more important in patients who require OLV.

Project description:Cellular level changes that lead to interstitial lung disease (ILD) may take years to become clinically apparent and have been termed preclinical ILD. Incidentally identified interstitial lung abnormalities (ILA) are increasingly being recognized on chest computed tomographic scans done as part of lung cancer screening and for other purposes. Many individuals found to have ILA will progress to clinically significant ILD. ILA are independently associated with greater risk of death, lung function decline, and incident lung cancer. Current management recommendations focus on identifying individuals with ILA at high risk of progression, through a combination of clinical and radiological features.

Project description:ObjectiveCombination treatment with ramucirumab and paclitaxel shows significant efficacy in patients with advanced gastric cancer as a second-line standard therapy. However, limited information is available about the development of pneumonitis associated with this treatment in clinical practice. This study aimed to characterize this form of pneumonitis and identify the risk factors for its onset.MethodsWe retrospectively analyzed the medical records of 44 patients with gastric cancer who received combination treatment with ramucirumab and paclitaxel from 2016 to 2017. Then, the clinicopathological characteristics of patients who developed treatment-related pneumonitis were evaluated and further compared with those of patients who did not.ResultsSix patients (13.6%) developed pneumonitis within five treatment cycles, and in five cases, remission was observed after cessation of combination treatment alone. The onset of pneumonitis was independently associated with pre-existing interstitial lung disease (ILD) (p = 0.025; odds ratio = 206.4). Patients with pneumonitis showed reduced time to treatment failure (median 56 vs. 138 days; p = 0.008), as compared with those without pneumonitis. Most patients with pre-existing ILD with a usual interstitial pneumonia (UIP) pattern developed pneumonitis.ConclusionsIn clinical practice, pneumonitis associated with the combination treatment of ramucirumab and paclitaxel was generally mild, but common. Patients with gastric cancer with pre-existing ILD, particularly those presenting with a UIP pattern, undergoing this combination treatment, should be carefully monitored for the development of treatment-related pneumonitis.

Project description:BackgroundInterstitial lung diseases (ILDs) are a group of pulmonary disorders affecting the lung's structure. Acute exacerbation of ILD (AE-ILD) following medical procedures is a significant clinical concern. Lung cryoprobe transbronchial biopsy (cryobiopsy) is a relatively new diagnostic technique for ILD, but data on AE-ILD post-cryobiopsy is limited. This study aims to fill this gap by examining the prevalence, risk factors, and outcomes of AE-ILD following cryobiopsy.MethodsThis multicenter retrospective study analyzed data from patients who underwent cryobiopsy for ILD diagnosis at three U.S. institutions between January 2014 and August 2022. The study included patients over 18 years with confirmed or suspected ILD, categorized into those who experienced AE-ILD post-cryobiopsy and those who did not.ResultsOut of 111 patients, 3.6% experienced AE-ILD, with a 50% mortality rate in these cases. The study cohort was predominantly white, with a median age of 69.0 years. Common comorbidities included tobacco use and hypertension. Patients who developed AE-ILD had an increased median number of biopsies. The overall 30-day mortality was 1.8%. Overall complication rate was 32%, including pneumonia, pneumothorax, AE-ILD, and bleeding requiring intervention. The study findings suggest that bronchoscopic cryobiopsy may be associated with lower overall mortality, particularly in patients with compromised lung function.ConclusionsThis study provides significant insights into AE-ILD following cryobiopsy, underscoring the need for careful patient selection and procedural assessment. While cryobiopsy may offer a safer alternative to surgical lung biopsy in specific patient cohorts, the elevated risk of AE-ILD necessitates further research to optimize patient outcomes and procedural safety.
