Abstract

BACKGROUND:We examined whether fluorine-18 2-fluoro-2-deoxy-D-glucose positron emission tomography/computed tomography (18F-FDG PET/CT) performed before chemotherapy could predict the onset of acute exacerbation of interstitial lung disease (AE-ILD) in patients with lung cancer and ILD treated with chemotherapy. METHODS:Thirty-three patients with lung cancer and ILD who underwent 18F-FDG PET/CT and were treated with chemotherapy at Kumamoto University Hospital between April 2006 and March 2018 were retrospectively analyzed. The maximum standardized uptake value (SUVmax) of interstitial lesions was measured to quantify the background ILD activity. A prediction model of AE-ILD was developed using logistic regression analyses for the SUVmax, and receiver operating characteristic (ROC) curve analyses were conducted. RESULTS:Among the 33 patients, 7 experienced AE-ILD. The SUVmax of contralateral interstitial lesions was significantly higher in patients with vs. without AE-ILD (median SUVmax: 2.220 vs. 1.795, P = 0.025). Univariable logistic regression analyses showed that the SUVmax of contralateral interstitial lesions trended towards being significantly associated with the onset of AE-ILD [odds ratio: 8.683, 95% confidence interval (CI) 0.88-85.83, P = 0.064]. The area under the ROC curve of the SUVmax for predicting AE-ILD was 0.780 (95% CI 0.579-0.982, P = 0.025). The optimal cut-off value for SUVmax was 2.005, with sensitivity and specificity values of 0.857 and 0.769, respectively. CONCLUSIONS:The SUVmax of contralateral interstitial lesions in 18F-FDG PET/CT images might be useful for predicting the onset of AE-ILD in patients with lung cancer and ILD treated with chemotherapy.

摘要

背景: 我们研究了化疗前进行的氟-18 2-氟-2-脱氧-d-葡萄糖正电子发射断层扫描/计算机断层扫描 (18F-FDG PET/CT) 是否可以预测间质性肺疾病 (AE-ILD) 急性加重的发生在接受化疗的肺癌和 ILD 患者中。 方法: 回顾性分析 2006年4月至 2018年3月在熊本大学医院接受 18F-FDG PET/CT 并接受化疗的 33 例肺癌合并 ILD 患者的临床资料。测量间质病变的最大标准化摄取值 (SUVmax),量化背景 ILD 活性。使用 SUVmax 的 logistic 回归分析建立 AE-ILD 的预测模型,并进行受试者工作特征 (ROC) 曲线分析。 结果: 33 例患者中,7 例发生 AE-ILD。与无 AE-ILD 的患者相比,对侧间质病变的 SUVmax 显著升高 (中位 SUVmax: 2.220 vs. 1.795,p = 0.025)。单变量 logistic 回归分析显示,对侧间质病变的 SUVmax 倾向于与 AE-ILD 的发病显著相关 [比值比: 8.683,95% 置信区间 (CI) 0.88-85.83, P = 0.064]。SUVmax 预测 AE-ILD 的 ROC 曲线下面积为 0.780 (95% CI 0.579 ~ 0.982,p = 0.025)。SUVmax 的最佳临界值为 2.005,敏感性和特异性值分别为 0.857 和 0.769。 结论: 18F-FDG PET/CT 显像对侧间质病变的 SUVmax 可用于预测接受化疗的肺癌和 ILD 患者发生 AE-ILD。

METHODS:OBJECTIVES:To asses the clinical course in RA-related interstitial lung disease (RA-ILD) patients with and without rituximab (RTX). The influence of other variables was also evaluated. METHODS:A longitudinal multicentre study was conducted in RA diagnosed with ILD from 2007 until 2018 in Madrid. Patients were included in a registry [pNEumology RhEumatology Autoinmune diseases (NEREA)] from the time of ILD diagnosis. The main endpoint was functional respiratory impairment (FI), when there was a decline ≥5% in the predicted forced vital capacity compared with the previous one. Pulmonary function was measured at baseline and in follow-up visits every 6-12 months. The independent variable was therapy with RTX. Covariables included sociodemographic, clinical, radiological and other therapies. Survival techniques were used to estimate the incidence rate (IR) and 95% CI of functional impairment, expressed per 100 patient-semesters. Cox multivariate regression models were run to examine the influence of RTX and other covariates on FI. Results were expressed as the hazard ratio (HR) and CI. RESULTS:A total of 68 patients were included. FI occurred in 42 patients [IR 23.5 (95% CI 19, 29.1)] and 50% of them had FI within 1.75 years of an ILD diagnosis. A multivariate analysis showed that RTX exposure resulted in a lower risk of FI compared with non-exposure [HR 0.51 (95% CI 0.31, 0.85)]. Interstitial pneumonia, glucocorticoids, disease activity and duration also influenced FI. CONCLUSION:RA-ILD patients deteriorate over time, with the median time free of impairment being <2 years. Patients exposed to RTX had a higher probability of remaining free of FI compared with other therapies. Other factors have also been identified. Key words: rheumatoid arthritis, interstitial lung disease, observational study, rituximab and prognosis

METHODS:The safety of anti-programmed cell death 1 (PD-1) antibody for patients with preexisting interstitial lung disease (ILD) remains unknown. The aim of this study was to evaluate the dependence of preexisting ILD on anti-PD-1 antibody-induced pneumonitis in non-small cell lung cancer (NSCLC) patients. We retrospectively reviewed the association of preexisting ILD with the incidence, radiographic pattern, and outcome of pneumonitis in NSCLC patients receiving anti-PD-1 antibody. A total of 331 patients were included in this study. Of these patients, 17 had preexisting ILD. The incidence of pneumonitis was higher among the patients with preexisting ILD than among those without preexisting ILD (29% vs. 10%, P  = 0.027). The distributions of the CT appearances at the onset of anti-PD-1 antibody-induced pneumonitis were as follows: for the patients with preexisting ILD, two patients (40%) had diffuse alveolar damage (DAD), one patient each with organizing pneumonia-like (OP), hypersensitivity pneumonitis (HP), and other patterns (20% each); for the patients without preexisting ILD, 19 patients (61%) had OP, 8 (26%) had HP, 3 (10%) had DAD, and 1 (3.2%) had other patterns. The median onset time from the initiation of anti-PD-1 antibody treatment until the development of pneumonitis was 1.3 months (range 0.3–2.1 months) for the patients with preexisting ILD and 2.3 months (range 0.2–14.6 months) for the patients without preexisting ILD. Careful attention to the development of pneumonitis is needed, especially within the first 3 months after the start of anti-PD-1 antibody treatment, when using anti-PD-1 antibody to treat patients with preexisting ILD.

METHODS::Bacteria of the Burkholderia cepacia complex (Bcc) are ubiquitous multidrug resistant organisms and opportunistic pathogens capable of causing life threatening lung infections among cystic fibrosis (CF) patients. No effective therapies are currently available to eradicate Bcc bacteria from CF patients, as these organisms are inherently resistant to the majority of clinically available antimicrobials. An immunoproteomics approach was used to identify Bcc proteins that stimulate the humoral immune response of the CF host, using bacterial cells grown under conditions mimicking the CF lung environment and serum samples from CF patients with a clinical record of Bcc infection. 24 proteins of the Bcc strain B. cenocepacia J2315 were identified as immunoreactive, 19 here reported as immunogenic for the first time. Ten proteins were predicted as extracytoplasmic, 9 of them being conserved in Bcc genomes. The immunogenic Bcc extracytoplasmic proteins are potential targets for development of novel therapeutic strategies and diagnostic tools to protect patients against the onset of chronic Bcc lung infections.
