RESUMO

In the FUGA-BT trial (JCOG1113), gemcitabine plus S-1 (GS) showed non-inferiority to gemcitabine plus cisplatin (GC) in overall survival (OS) with good tolerance for patients with advanced biliary tract cancer (BTC). We performed a subgroup analysis focused on the elderly cohort of this trial. All 354 enrolled patients in JCOG1113 were classify into two groups; < 75 (non-elderly) and ≥ 75 years (elderly) group. We investigated the influence of age on the safety analysis, including the incidence of chemotherapeutic adverse events and the efficacy analysis, including OS. There were no remarkable differences in OS between the elderly (n = 60) and the non-elderly groups (n = 294). In the elderly group, median OS was 12.7 and 17.7 months for those who received GC (n = 20) and GS (n = 40), respectively. The prevalence of all-grade adverse events was similar between the elderly and the non-elderly groups. However, among the elderly group, Grade ≥ 3 hematological adverse events were more frequently observed in the GC arm than in the GS arm. The clinical outcomes of combination chemotherapy in elderly patients with advanced BTC were comparable to non-elderly patients. GS may be the more favorable treatment for elderly patients with advanced BTC.

RESUMO

Diagnosis of pulmonary lymphoma using small tissue samples is difficult and often requires surgical procedures; thus, a less invasive sampling method is desirable. We previously showed that pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma can be diagnosed by detecting MALT lymphoma translocation gene 1 (MALT1) translocations in bronchoalveolar lavage fluid (BALF) cells. Analysis of B-cell clonality based on immunoglobulin heavy chain (IGH) gene rearrangements was also reportedly useful for diagnosing pulmonary lymphoma. The aim of this prospective multicenter study was to evaluate the yet unknown diagnostic potential of combined detection of MALT1 translocations and clonality using BALF. We analyzed B- and T-cell clonality based on IGH and T-cell receptor (TCR) rearrangements together with MALT1 translocations using BALF of patients with clinically suspected pulmonary lymphomas. In total, 39 patients were evaluated and categorized into three groups: B-cell lymphoma, lymphoproliferative disorders, and other diseases. IGH rearrangement detection for B-cell lymphoma diagnosis exhibited sensitivity and specificity of 88.9% and 90.0%, respectively. TCR rearrangements were not observed in patients with B-cell lymphomas. The presence of IGH rearrangements together with the absence of TCR rearrangements indicated 96.0% specificity for the diagnosis of B-cell lymphoma. The sensitivity and specificity of MALT1 translocations for diagnosing MALT lymphoma were 28.6% and 100%, respectively. The combined detection of lymphocyte clonality and MALT1 translocations using BALF is suitable for screening and diagnosis of B-cell lymphomas. Analysis of specific genes such as MALT1 should improve the precision of B-cell lymphoma diagnosis.

RESUMO

BACKGROUND: Endoscopic duodenal stent placement is an alternative technique to gastrojejunostomy for gastric outlet obstruction due to pancreatic cancer. We compared the efficacy of endoscopic duodenal stent placement with that of gastrojejunostomy for treating patients with pancreatic cancer who are candidates for intensive combination chemotherapies as the first line of treatment. METHODS: This retrospective observational study included 100 patients from 18 institutions in Japan. Inclusion criteria were as follows: (1) cytologically or histologically confirmed adenocarcinoma of the pancreas, (2) good performance status, (3) gastric outlet obstruction scoring system score of 0-1 and (4) no history of treatment for pancreatic cancer. RESULTS: There was no significant difference in the background characteristics of patients in the endoscopic duodenal stent placement (n = 57) and gastrojejunostomy (n = 43) groups. The median overall survival in the endoscopic duodenal stent placement and gastrojejunostomy groups was 5.9 and 6.0 months, respectively. Clinical success was achieved in 93 cases; the median time to food intake resumption was significantly shorter in the endoscopic duodenal stent placement group (median: 3 days, n = 54) than in the gastrojejunostomy group (median: 5 days, n = 43). Chemotherapy was introduced in 63% of the patients in both groups after endoscopic duodenal stent placement or gastrojejunostomy. Chemotherapy was started earlier in the endoscopic duodenal stent placement group (median: 14 days) than in the gastrojejunostomy (median: 32 days) group. CONCLUSIONS: Endoscopic duodenal stent placement showed similar or better clinical outcomes than gastrojejunostomy. Thus, it might be a promising option in patients with good performance status.

RESUMO

BACKGROUND: Patients diagnosed with pleuroparenchymal fibroelastosis (PPFE) exhibit unique clinical features, including upper lobe-dominant lung involvement and platythorax (or flattened thoracic cage). Although platythorax have been shown to be a sign of disease progression, the temporal relationship between the progression of platythorax and the extent of lung involvement has not been closely investigated. METHODS: We retrospectively investigated patients diagnosed with PPFE, who did not exhibit fibrotic lesions other than PPFE in the lower lobes. We estimated the fibrosis score, which is a visual score indicating the percentage of lung parenchyma occupied by the disease on computed tomography images selected every 2 cm from the lung apex to the lung base, and the flat chest index (the ratio of the anteroposterior diameter of the thoracic cage to the transverse diameter of the thoracic cage). Additionally, we investigated serial changes in the flat chest index and fibrosis score. RESULTS: A total of 29 patients were included in this study. The fibrosis score was found to be weakly and inversely correlated with forced vital capacity %predicted at the diagnosis (r = -0.40, p = 0.038). Furthermore, the annual changes in the flat chest index and fibrosis score was found to be moderately and inversely correlated (r = -0.663, p = 0.0037). CONCLUSIONS: These results indicate that there is a causal relationship between the progression of fibroelastosis and that of platythorax in patients with PPFE.

RESUMO

Lung adenocarcinoma can rarely present with imaging findings that mimic fibrotic lesions of interstitial pneumonia. Asymmetric lung involvement and symptoms of haemoptysis may be the clinical clues to the suspicion of lung neoplasm rather than fibrotic lung disease.

RESUMO

OBJECTIVES: S-1 monotherapy with concurrent radiotherapy (RT) is a standard of care for patients with locally advanced pancreatic cancer (LAPC). Although renal dysfunction increases S-1 monotherapy toxicity, its effect in S-1 with concurrent RT remains unknown. We evaluated the effect of renal function on the safety of S-1 with RT for LAPC. METHODS: We performed an integrated exploratory post hoc analysis of data from 2 prospective studies (JCOG1106 and LAPC-S1RT), where patients with LAPC received RT (50.4 Gy/28 fraction for 5.5 weeks) and concurrent S-1 (40 mg/m2 per dose, twice daily on the day of irradiation). We split the patients into high creatinine clearance (CCr; ≥80 mL/min) and low CCr (<80 mL/min) groups and compared the findings to determine treatment safety. RESULTS: The high and low CCr groups showed a median of 97.5 (range, 80.0-194.6) and 64.4 (range, 50.0-78.3) mL/min, respectively. The low CCr group presented more adverse reactions (ARs) of grade 3 or higher and gastrointestinal ARs of grade 2 or higher than the high CCr group (30.8% vs 15.8% and 51.9% vs 36.8%). CONCLUSIONS: The incidence of ARs associated with concurrent S-1 and RT increases in patients with low CCr; therefore, ARs should be duly considered in such patients.

RESUMO

INTRODUCTION: It is not uncommon for patients hospitalized with pneumonia to experience an early relapse. Here, we investigated the factors related to pneumonia recurrence in Japan. PURPOSE: We aimed to elucidate the factors related to early recurrence after completion of pneumonia treatment. METHODS: We examined 696 patients with community-acquired pneumonia (CAP) and nursing and healthcare-associated pneumonia (NHCAP) who were admitted to our hospital between October 2010 and February 2018, excluding those who died during hospitalization. Logistic regression analysis was used to assess the endpoint of recurrence within 30 days after the end of antibiotic treatment. RESULTS: NHCAP, chronic lung disease and duration of antibiotic treatment were significant risk factors for recurrence of pneumonia within 30 days after antibiotic discontinuation. Aspiration pneumonia was not be a significant factor in the early recurrence of pneumonia. CONCLUSIONS: Long-term use of antimicrobials may be a risk factor in early recurrence of pneumonia.

RESUMO

Amyloidosis is a rare disease characterized by the deposition of abnormal proteins in extracellular tissues. We herein report a case with instructive radiologic features of nodular pulmonary amyloidosis associated with Sjögren's syndrome. A 67-year-old woman was referred to our department because of an abnormal chest radiograph. Chest computed tomography revealed multiple round cysts accompanied by calcified nodules. The patient was clinically diagnosed with primary Sjögren's syndrome and pathologically diagnosed with nodular pulmonary amyloidosis (light chain, kappa). Although multiple lung cysts have many etiologies, the presence of calcified nodules associated with multiple lung cysts is useful for narrowing down the differential diagnosis.

RESUMO

INTRODUCTION: The COVID-19 pandemic has emerged worldwide. Although several medications have been approved for treating moderate-to-severe COVID-19, very few treatment strategy has been established for patients with mild COVID-19 who do not require oxygen administration. Clarithromycin is a macrolide antimicrobial agent that has been widely used for bacterial respiratory infectious diseases. Clarithromycin also acts an immunomodulating drug and suppresses cytokine storms in viral respiratory diseases, including influenza. In this study, we aim to evaluate the efficacy of clarithromycin in patients with mild COVID-19. METHODS AND ANALYSIS: This is an exploratory, multicentre, open-label, randomised controlled trial. This study was initiated in May 2021 and will end in July 2022. Patients with mild COVID-19 pneumonia who do not require oxygen administration will be enrolled and randomly assigned in a 1:1:1 ratio to group A (administration of clarithromycin 800 mg/day), group B (administration of clarithromycin 400 mg/day) or group C (standard treatment without clarithromycin). The planned number of enrolled patients is 60 (20 patients × three groups). The primary endpoint is the number of days required to improve the clinical symptoms as measured by the severity score. Secondary endpoints include days for recovery of the body temperature, proportion of patients with oxygen administration, inflammatory cytokines, viral load, serum immunoglobulins, peripheral blood lymphocytes, blood biomarkers and pneumonia infiltrations. ETHICS AND DISSEMINATION: The study protocol was approved by the Clinical Research Review Board of Nagasaki University in accordance with the Clinical Trials Act in Japan. The study will be conducted in accordance with the Declaration of Helsinki, the Clinical Trials Act and other current legal regulations in Japan. Written informed consent will be obtained from all the participants. The results of this study will be reported as journal publications. TRIAL REGISTRATION NUMBER: jRCTs071210011.

RESUMO

BACKGROUND/AIM: Aspergillus is often detected in respiratory samples from patients with chronic respiratory diseases, including pulmonary fibrosis, suggesting that it can easily colonize the airways. To determine the role of Aspergillus colonization in pulmonary fibrosis, we cultured human lung epithelial A549 cells or murine embryo fibroblast NIH/3T3 cells with Aspergillus conidia in 3D floating culture representing the microenvironment. MATERIALS AND METHODS: Cells were cultured in two-dimensional (2D) and three-dimensional floating (3DF) culture with heat-inactivated Aspergillus fumigatus (AF) 293 conidia at an effector-to-target cell ratio of 1:10 (early-phase model) and 1:100 (colonization model), and RNA-sequencing and Western blots (WB) were performed. RESULTS: AF293 conidia reduced A549 cell growth in 2D and 3DF cultures and induced apoptosis in A549 spheroids in 3DF culture. RNA-sequencing revealed the increased expression of genes associated with interferon-mediated antiviral responses including MX dymamin-like GTPase 1 (MX1). Interestingly, the decreased expression of genes associated with the cell cycle was observed with a high concentration of AF293 conidia. WB revealed that epithelial-mesenchymal transition was not involved. Notably, AF293 conidia increased NIH/3T3 growth only in 3DF culture without inducing an apoptotic reaction. RNA-sequencing revealed the increased expression of genes associated with interferon signalling, including MX2; however, the decreased expression of genes associated with the cell cycle was not observed. CONCLUSIONS: AF affects both apoptosis of epithelial cells and the growth of fibroblasts. A deeper understanding of the detailed mechanisms underlying Aspergillus-mediated signaling pathway in epithelial cells and fibroblasts will help us to understand the lung microenvironment.

RESUMO

BACKGROUND: Clinical course of pleuroparenchymal fibroelastosis (PPFE) shows considerable variation among patients, but there is no established prognostic prediction model for PPFE. METHODS: The prediction model was developed using retrospective data from two cohorts: our single-center cohort and a nationwide multicenter cohort involving 21 institutions. Cox regression analyses were used to identify prognostic factors. The total score was defined as the weighted sum of values for the selected variables. The performance of the prediction models was evaluated by Harrell's concordance index (C-index). We also examined the usefulness of the gender-age-physiology (GAP) model for predicting the prognosis of PPFE patients. RESULTS: We examined 104 patients with PPFE (52 cases from each cohort). In a multivariate Cox analysis, a lower forced vital capacity (FVC [defined as FVC < 65%]; hazard ratio [HR], 2.23), a history of pneumothorax (HR, 3.27), the presence of a lower lobe interstitial lung disease (ILD) (HR, 2.31), and higher serum Krebs von den Lungen-6 (KL-6) levels (> 550 U/mL, HR, 2.56) were significantly associated with a poor prognosis. The total score was calculated as 1 × (FVC, < 65%) + 1 × (history of pneumothorax) + 1 × (presence of lower lobe ILD) + 1 × (KL-6, > 550 U/mL). PPFE patients were divided into three groups based on the prognostic score: stage I (0-1 points), stage II (2 points), and stage III (3-4 points). The survival rates were significantly different in each stage. The GAP stage was significantly associated with the prognosis of PPFE, but no difference was found between moderate (stage II) and severe (stage III) disease. Our new model for PPFE patients (PPFE Prognosis Score) showed better performance in the prediction of mortality in comparison to the GAP model (C-index of 0.713 vs. 0.649). CONCLUSIONS: Our new model for PPFE patients could be useful for predicting their prognosis.

RESUMO

BACKGROUND: Some patients with idiopathic interstitial pneumonia (IIP) show autoimmune features. Interstitial pneumonia with autoimmune features (IPAF) was recently proposed as a research concept in these patients. However, retrospective studies reported conflicting results of its prognosis. Therefore, this study was conducted to prospectively evaluate the clinical significance of autoimmune features in patients with IIP. METHODS: This nationwide multicentre study prospectively enrolled consecutive patients with IIP. At the diagnosis, we systematically evaluated 63 features suggestive of connective tissue diseases using a checklist including symptoms/signs and autoantibodies, which contained most items of the IPAF criteria and followed up with the patients. Clinical phenotypes were included in a cluster analysis. RESULTS: In 376 patients with IIP enrolled, 70 patients (18.6%) met the IPAF criteria. The proportion of patients with IPAF was significantly lower in idiopathic pulmonary fibrosis (IPF) than in non-IPF (6.0% vs 24.3%, respectively). During a median observation period of 35 months, patients with IPAF more frequently developed systemic autoimmune diseases and had less frequent acute exacerbation of IIPs than patients with non-IPAF. IPAF diagnosis was significantly associated with better survival and was an independent positive prognostic factor in total and patients with non-IPF. Cluster analysis by similarity of clinical phenotypes identified a cluster in which there was a higher number of women, and patients had more autoimmune features and a better prognosis than other clusters. INTERPRETATION: These observations suggest that some patients with IIP show autoimmune features with distinct characteristics and favourable prognosis. However, we were not able to determine the appropriate therapies for these patients.

RESUMO

SARS-CoV-2 infection presents clinical manifestations ranging from asymptomatic to fatal respiratory failure. Despite the induction of functional SARS-CoV-2-specific CD8+ T-cell responses in convalescent individuals, the role of virus-specific CD8+ T-cell responses in the control of SARS-CoV-2 replication remains unknown. In the present study, we show that subacute SARS-CoV-2 replication can be controlled in the absence of CD8+ T cells in cynomolgus macaques. Eight macaques were intranasally inoculated with 105 or 106 TCID50 of SARS-CoV-2, and three of the eight macaques were treated with a monoclonal anti-CD8 antibody on days 5 and 7 post-infection. In these three macaques, CD8+ T cells were undetectable on day 7 and thereafter, while virus-specific CD8+ T-cell responses were induced in the remaining five untreated animals. Viral RNA was detected in nasopharyngeal swabs for 10-17 days post-infection in all macaques, and the kinetics of viral RNA levels in pharyngeal swabs and plasma neutralizing antibody titers were comparable between the anti-CD8 antibody treated and untreated animals. SARS-CoV-2 RNA was detected in the pharyngeal mucosa and/or retropharyngeal lymph node obtained at necropsy on day 21 in two of the untreated group but undetectable in all macaques treated with anti-CD8 antibody. CD8+ T-cell responses may contribute to viral control in SARS-CoV-2 infection, but our results indicate possible containment of subacute viral replication in the absence of CD8+ T cells, implying that CD8+ T-cell dysfunction may not solely lead to viral control failure.

RESUMO

INTRODUCTION: Fatigue, caused by dyspnea associated with progression of interstitial pneumonia (IP), can negatively affect patients' quality of life (QOL). Ninjin'yoeito (NYT), a Chinese herbal medicine, is prescribed for general symptoms of fatigue and for fatigue associated with various respiratory diseases. However, there is a lack of integrated research on the effects of NYT in patients with IP. Therefore, we retrospectively investigated the efficacy of NYT in patients with IP and fatigue. MATERIALS AND METHODS: From the IP patients who had taken NYT, 19 who met the following inclusion criteria were included: (1) age of ≥20 years, (2) fatigue, and (3) history of NYT administration. The primary endpoint was fatigue, which was assessed using the Chalder Fatigue Scale (CFS). The secondary endpoints were loss of appetite and dyspnea, which were evaluated using the Simplified Nutritional Appetite Questionnaire (SNAQ) and modified Medical Research Council (mMRC) scores, respectively. All items were measured before and after 12 weeks of NYT administration. RESULTS: In the enrolled 19 patients (male, 12; female, 7; mean age, 65.8 ± 12.7 years), the underlying diseases were idiopathic pulmonary fibrosis (n = 8), idiopathic pleuroparenchymal fibroelastosis (n = 5), connective tissue disease-related interstitial pneumonia (n = 2), chronic hypersensitivity pneumonitis (n = 3), and nonspecific interstitial pneumonia (n = 1). The CFS score decreased from 17.1 ± 6.8 before administration to 13.4 ± 5.7 after administration of NYT (p = 0.0389). The SNAQ score did not change markedly. The median mMRC score decreased from 3 to 2, however, the difference was not significant. CONCLUSION: Many subtypes of IP are progressive, and a cure cannot be expected in cases of irreversible lung fibrosis. Therefore, a multifaceted approach to improve and maintain the QOL is needed in addition to the standard of care. This study showed that NYT can improve fatigue and help maintain the QOL in IP patients.

RESUMO

Antibody responses are crucial for the control of virus infection. Understanding of the mechanism of antibody induction is important for the development of a vaccine eliciting effective anti-virus antibodies. Virus-specific B cell receptor (BCR)/antibody repertoires are different among individuals, but determinants for this difference remain largely unclear. We have recently reported that a germline BCR immunoglobulin (IgG) gene polymorphism (VH3.33_ET or VH3.33_VI) in rhesus macaques is the determinant for induction of potent B404-class anti-simian immunodeficiency virus (SIV) neutralizing antibodies in neutralization-sensitive SIVsmH635FC infection. In the present study, we examined whether neutralization-resistant SIVsmE543-3 infection can induce the anti-SIV neutralizing antibodies associated with the germline VH3.33 polymorphism. Anti-SIVsmE543-3 neutralizing antibodies were induced in all the macaques possessing the VH3.33_ET allele, but not in those without VH3.33_ET, in the chronic phase of SIVsmE543-3 infection. Next generation sequencing analysis of BCR VH genes found B404-class antibody sequences only in those with VH3.33_ET. These results indicate that anti-SIVsmE543-3 neutralizing antibody induction associated with the germline BCR IgG gene polymorphism can be triggered by infection with neutralization-resistant SIVsmE543-3. This animal model would be useful for the elucidation of the mechanism of potent antibody induction against neutralization-resistant viruses.

RESUMO

CASE PRESENTATION: A 63-year-old, non-smoking Asian woman presented to our hospital due to abnormal findings on chest radiography. She had no history of dust exposure. Chest radiography and CT imaging showed patchy ground-glass attenuation (GGA) in the bilateral lower lung lobes, a ground-glass nodule in the right lower lung lobe (diameter, 9.8 mm), and some thin-walled cysts in both lungs (Fig 1). Thickening of the interlobular septa, mediastinal lymphadenopathy, and pleural effusion were not evident. Video-assisted thoracic surgery was performed for the examination of the nodule and the background lung disease, and the nodule was histologically diagnosed as lung adenocarcinoma. Simultaneously, the lung background showed diffuse lymphocytic infiltration in the alveolar septum and peribronchovascular interstitium (Fig 2). There were no symptoms suggestive of autoimmune diseases such as dryness, arthralgia, skin rash, or fever. The patient was followed up without treatment for the interstitial lung disease.

RESUMO

INTRODUCTION: Idiopathic pulmonary fibrosis (IPF) is a fibrotic disease of unknown aetiology with a poor prognosis. Several clinical trials of nintedanib in patients with IPF have reported its inhibitory effect on reduced lung function, incidence of acute exacerbation of IPF and worsened health-related quality of life. Although nintedanib has a manageable safety and tolerability profile over long-term use, it was discontinued in over 20% of patients because of adverse events such as diarrhoea and liver dysfunction. This might explain why nintedanib use in patients with IPF is not widespread, especially among patients with early-stage IPF. In the present study, we aimed to clarify the efficacy, safety and tolerability of nintedanib in patients with stage I/II IPF, based on the Japanese IPF disease severity staging classification system. METHODS AND ANALYSIS: This is an ongoing, prospective, multicentre observational cohort study of patients with stage I/II IPF who will start receiving nintedanib. Totally, 215 patients at 35 sites in Kyushu and Okinawa, Japan will be enrolled and followed up for 3 years. Nintedanib therapy would be initiated at the discretion of the investigator. The primary endpoint, change in forced vital capacity (FVC) at 156 weeks, will be shown as the mean change in FVC from baseline to week 156 with 95% CIs estimated using the Wald method. The safety endpoint-occurrence of adverse events-will be assessed in each system organ class/preferred term. ETHICS AND DISSEMINATION: The study protocol and informed consent documents were approved by the Institutional Review Board at Nagasaki University Hospital (approval number 19102146) and each participating site. Written informed consent was obtained from all participants. Patient recruitment has begun. The results will be disseminated through scientific peer-reviewed publications and national and international conferences. TRIAL REGISTRATION NUMBER: UMIN000038192.

RESUMO

JCOG1113 is a randomized phase III trial in patients with advanced biliary tract cancers (BTCs) (UMIN000001685), and gemcitabine plus S-1 (GS) was not inferior to gemcitabine plus cisplatin (GC). However, poor renal function often results in high toxicity of S-1. Therefore, we examined whether GS can be recommended for patients with low creatinine clearance (CCr). Renal function was classified by CCr as calculated by the Cockcroft-Gault formula: high CCr (CCr ≥ 80 ml/min) and low CCr (80 > CCr ≥ 50 ml/min). Of 354 patients, 87 patients on GC and 91 on GS were included in the low CCr group, while there were 88 patients on GC and 88 patients on GS in the high CCr group. The HR of overall survival for GS compared with GC was 0.687 (95% CI 0.504-0.937) in the low CCr group. Although the total number of incidences of all Grade 3-4 non-haematological adverse reactions was higher (36.0% vs. 11.8%, p = 0.0002), the number of patients who discontinued treatment was not different (14.1% vs. 16.9%, p = 0.679) for GS compared with GC in the low CCr group.
