Abstract
This study aimed to evaluate diagnostic accuracy of SARS-CoV-2 RNA detection in saliva samples treated with a guanidine-based or guanidine-free inactivator, using nasopharyngeal swab samples (NPS) as referents. Based on the NPS reverse transcription-polymerase chain reaction (RT-PCR) results, participants were classified as with or without COVID-19. Fifty sets of samples comprising NPS, self-collected raw saliva, and saliva with a guanidine-based, and guanidine-free inactivator were collected from each group. In patients with COVID-19, the sensitivity of direct RT-PCR using raw saliva and saliva treated with a guanidine-based and guanidine-free inactivator was 100.0%, 65.9%, and 82.9%, respectively, with corresponding concordance rates of 94.3% (κ=88.5), 82.8% (κ=64.8), and 92.0% (κ=83.7). Among patients with a PCR Ct value of <30 in the NPS sample, the positive predictive value for the three samples was 100.0%, 80.0%, and 96.0%, respectively. The sensitivity of SARS-CoV-2 RNA detection was lower in inactivated saliva than in raw saliva and lower in samples treated with a guanidine-based than with a guanidine-free inactivator. However, in individuals contributing to infection spread, inactivated saliva showed adequate accuracy regardless of the inactivator used. Inactivators can be added to saliva samples collected for RT-PCR to reduce viral transmission risk while maintaining adequate diagnostic accuracy.

Abstract
BACKGROUND While the prevalence of severe cases and mortality rate of coronavirus disease 2019 (COVID-19) appear to be reducing, the clinical characteristics and severity of hospitalized patients with asthma and COVID-19 remain largely unknown. This study aimed to examine the association of asthma with COVID-19 severity and mortality risk. METHODS Data from the Japanese COVID-19 Registry Database were used to investigate the association between COVID-19 and asthma. This study focused on patients hospitalized for COVID-19 in 690 facilities from January 31, 2020, to December 31, 2022. Multivariate analysis using logistic regression was conducted to assess whether asthma, compared with other conditions, represents a risk factor for mortality and invasive mechanical ventilation after COVID-19. RESULTS In total, 72,582 patients with COVID-19 were included in the analysis, of whom, 3731 were diagnosed with asthma. From January 2020 to June 2021, asthma showed no significant association with an increase in mortality (OR 0.837, 95% CI 0.639-1.080, p = 0.184) or invasive mechanical ventilation events (OR 1.084, 95% CI 0.878-1.326, p = 0.440). An analysis conducted after July 2021 yielded similar results. For patients with asthma, factors such as age, body-mass index, sex, and chronic kidney disease increased the risk of mechanical ventilation. However, non-vaccination status and high blood pressure increased the risk of mechanical ventilation during the second half of the study. CONCLUSION Patients with asthma did not have an increased risk of mortality or mechanical ventilation due to COVID-19. However, patients with asthma had a higher risk of more severe COVID-19 due to factors such as advancing age, elevated body-mass index, chronic kidney disease, and non-vaccination.

Abstract
BACKGROUND Granulocyte-macrophage colony stimulating factor (GM-CSF) inhalation may alleviate pulmonary inflammation caused by viral pneumonia. To investigate this, we evaluated its efficacy on COVID-19 pneumonia. METHODS This double-blind, randomised, placebo-controlled study (ClinicalTrials.gov: NCT04642950) evaluated patients in the first half of 2021 at seven Japanese hospitals. Hospitalised patients with COVID-19 pneumonia with moderate hypoxaemia inhaled sargramostim or placebo for 5 days. The primary endpoint was days to achieve a ≥ 2-category improvement from baseline on a modified 7-category ordinal scale. Secondary endpoints included degree of oxygenation, defined by amount of oxygen supply, and serum CCL17 level. RESULTS Seventy-five patients were randomly assigned in a 2:1 ratio to receive sargramostim or placebo, of which 47 and 23 were analysed, respectively. No difference was observed between groups regarding the primary endpoint (8.0 and 7.0 days for sargramostim and placebo, respectively) or in the secondary endpoints, except for CCL17. A post hoc sub-analysis indicated that endpoint assessments were influenced by concomitant corticosteroid therapy. When the cumulative corticosteroid dose was ≤500 mg during Days 1-5, recovery and oxygenation were faster in the sargramostim group than for placebo. Bolus dose corticosteroids were associated with temporarily impaired oxygenation and delayed clinical recovery. The increase in serum CCL17, a candidate prognostic factor, reflected improvement with sargramostim inhalation. The number of adverse events was similar between groups. Two serious adverse events were observed in the sargramostim group without causal relation. CONCLUSIONS Inhaled sargramostim was likely to be effective for COVID-19 pneumonia unless the concomitant corticosteroid dose was high.

Abstract
During an earlier multicenter, open-label, randomized controlled trial designed to evaluate the effectiveness of high-dose inhaled ciclesonide in patients with asymptomatic or mild coronavirus disease 2019 (COVID-19), we observed that worsening of shadows on CT without worsening of clinical symptoms was more common with ciclesonide. The present study sought to determine if an association exists between worsening CT shadows and impaired antibody production in patients treated with inhaled ciclesonide. Eighty-nine of the 90 patients in the original study were prospectively enrolled. After exclusions, there were 36 patients each in the ciclesonide and control groups. We analyzed antibody titers against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) nucleocapsid protein at various time points. Changes in viral load during treatment were compared. There was no significant difference in age, sex, body mass index, background clinical characteristics, or symptoms between the two groups. Although evaluation on day 8 suggested a greater tendency for worsening shadows on CT in the ciclesonide group (p = 0.072), there was no significant difference between them in the ability to produce antibodies (p = 0.379) or the maximum antibody titer during the clinical course. In both groups, worsening CT shadows and higher viral loads were observed on days 1-8, suggesting ciclesonide does not affect clearance of the virus (p = 0.134). High-dose inhaled ciclesonide did not impair production of antibodies against SARS-CoV-2 or affect elimination of the virus, suggesting that this treatment can be used safely in patients with COVID-19 patients who use inhaled steroids for asthma and other diseases.

Abstract
BACKGROUND Idiopathic interstitial pneumonias are an independent risk factor of lung cancer, and a chemotherapy-induced acute exacerbation is the most common lethal complication in Japanese patients. The safety and efficacy of carboplatin and weekly paclitaxel for the treatment of non-small cell lung cancer with idiopathic interstitial pneumonias has been previously reported in prospective studies. However, carboplatin + paclitaxel with bevacizumab is currently the standard therapy. We conducted a multicenter, phase II study to confirm the safety and efficacy of carboplatin + weekly paclitaxel + bevacizumab for the treatment of patients with lung cancer complicated by idiopathic interstitial pneumonias. METHODS Chemotherapy-naïve patients with advanced-stage or patients with post-operative recurrent non-squamous non-small cell lung cancer complicated by idiopathic interstitial pneumonias were enrolled. Patients received carboplatin (area under the curve: 5.0) and bevacizumab (15 mg/kg) on day 1 and paclitaxel (100 mg/m2) on days 1, 8, and 15 of each 4-week cycle. RESULTS Seventeen patients less than the predetermined number were enrolled and received a median of four treatment cycles (range: 1-6). One patient (5.9%; 95% confidence interval: 0.1-28.7%) had acute exacerbation of interstitial pneumonia related to the study treatment which improved after corticosteroid treatment. The overall response rate was 52.9%. The median progression-free survival, median survival time, and 1-year survival were 5.7 months, 12.9 months, and 52.9%, respectively. CONCLUSION The addition of bevacizumab to carboplatin and weekly paclitaxel might be safe and effective for the treatment of advanced non-small cell lung cancer complicated by idiopathic interstitial pneumonias.

Abstract
While high-level evidence is lacking, numerous retrospective studies have depicted the value of supplemental oxygen in idiopathic pulmonary fibrosis (IPF) and other interstitial lung diseases, and its use should be encouraged where necessary. The clinical course and survival of patients with IPF who have been introduced to oxygen therapy is still not fully understood. The objective of this study was to clarify overall survival, factors associated with prognosis, and causes of death in IPF patients after the start of oxygen therapy. This is a prospective cohort multicenter study, enrolling patients with IPF who started oxygen therapy at 19 hospitals with expertise in interstitial lung disease. Baseline clinical data at the start of oxygen therapy and 3-year follow-up data including death and cause of death were assessed. Factors associated with prognosis were analyzed using univariable and multivariable analyses. One hundred forty-seven eligible patients, of whom 86 (59%) were prescribed ambulatory oxygen therapy and 61 (41%) were prescribed long-term oxygen therapy, were recruited. Of them, 111 died (76%) during a median follow-up of 479 days. The median survival from the start of oxygen therapy was 537 ± 74 days. In the univariable analysis, low body mass index (BMI), low forced vital capacity (FVC), low diffusion capacity (DLCO), resting hypoxemia, short 6 min-walk distance, and high COPD assessment test (CAT) score were significantly associated with poor prognosis. Multivariable analysis revealed low BMI, low FVC, low DLCO, low minimum SpO2 on 6MWT, and high CAT score were independent factors for poor prognosis. The overall survival of IPF patients after starting oxygen therapy is about 1.5 years. In addition to pulmonary function tests, 6MWT and patient reported outcomes can be used to predict prognosis more accurately.Clinical Trial Registration: UMIN000009322.

Abstract
A 41-year-old man presented with chronic cough and chest pain. Laboratory tests revealed anemia, inflammation, hypoalbuminemia, polyclonal hypergammaglobulinemia, and elevated interleukin-6 levels. Computed tomography revealed diffuse bilateral pulmonary nodules and multicentric lymphadenopathy. Histopathology of the pulmonary nodule resembled pulmonary hyalinizing granuloma (PHG), whereas lymph node histopathology was consistent with idiopathic multicentric Castleman disease (iMCD). The patient was diagnosed with iMCD involving PHG-like pulmonary nodules. Little is known about the association between these two diseases, and the present case provides insights regarding the relationship between PHG and iMCD.

Abstract
The reverse transcription polymerase chain reaction (RT-PCR) offers high sensitivity, but has some drawbacks, such as the time required for the RNA extraction. Transcription reverse-transcription concerted reaction (TRC) Ready® SARS-CoV-2 i is easy to use and can be performed in about 40 minutes. TRC Ready® SARS-CoV-2 i and real-time one-step RT-PCR using the TaqMan probe tests of cryopreserved nasopharyngeal swab samples from patients diagnosed with COVID-19 were compared. The primary objective was to examine the positive and negative concordance rates. A total of 69 samples cryopreserved at -80° C were examined. Of the 37 frozen samples that were expected to be RT-PCR positive, 35 were positive by the RT-PCR method. TRC Ready® SARS-CoV-2 i detected 33 positive cases and 2 negative cases. One frozen sample that was expected to be RT-PCR positive was negative on both TRC Ready® SARS-CoV-2 i and RT-PCR. In addition, one frozen sample that was expected to be RT-PCR positive was positive by the RT-PCR method and negative by TRC Ready® SARS-CoV-2 i. Of the 32 frozen samples that were expected to be RT-PCR negative, both the RT-PCR method and TRC Ready® SARS-CoV-2 i yielded negative results for all 32 samples. Compared with RT-PCR, TRC Ready® SARS-CoV-2 i had a positive concordance rate of 94.3% and a negative concordance rate of 97.1%. TRC Ready® SARS-CoV-2 i can be utilized in a wide range of medical sites such as clinics and community hospitals due to its ease of operability, and is expected to be useful in infection control.

Abstract
A 70-year-old man began to cough. Chest X-ray showed a tumor in the center, pleural effusion on the left side, and diffuse granular shadows on the right side. Chest computed tomography (CT) showed bronchial wall thickening and numerous granular shadows. We suspected diffuse panbronchiolitis. Thus, transbronchial lung biopsy (TBLB) and transbronchial lung cryobiopsy (TBLC) were performed. The tissue size obtained was 1 mm by TBLB and 6 mm at 5 seconds by TBLC. Histological analysis of the TBLB specimen showed lymphocyte infiltration, no fibrosis in Hematoxylin-eosin (HE) staining, and no elastic fibers in Elastica van Gieson (EVG) staining. On the other hand, TBLC specimens showed inflammatory cell infiltration and fibrosis around the bronchioles in HE staining and hypertrophy of elastic fibers in EVG staining. It was diagnosed as diffuse panbronchiolitis (DPB) from clinical and pathological findings. Cryobiopsy is useful in diagnosing DPB as well as interstitial pneumonia and lung cancer.

Abstract
High-flow nasal cannula (HFNC) can be effective in treating type 1 respiratory failure by reducing the severity of coronavirus disease 2019 (COVID-19). The purpose of this study was to assess the reduction of disease severity and safety of HFNC treatment in patients with severe COVID-19. We retrospectively observed 513 consecutive patients with COVID-19 admitted to our hospital from January 2020 to January 2021. We included patients with severe COVID-19 who received HFNC for their deteriorating respiratory status. HFNC success was defined as improvement in respiratory status after HFNC and transfer to conventional oxygen therapy, while HFNC failure was defined as transfer to non-invasive positive pressure ventilation or ventilator, or death after HFNC. Predictive factors associated with failure to prevent severe disease were identified. Thirty-eight patients received HFNC. Twenty-five (65.8%) patients were classified in the HFNC success group. In the univariate analysis, age, history of chronic kidney disease (CKD), non-respiratory sequential organ failure assessment (SOFA) ≥ 1, oxygen saturation to fraction of inspired oxygen ratio (SpO2/FiO2) before HFNC ≤ 169.2, were significant predictors of HFNC failure. Multivariate analysis revealed that SpO2/FiO2 value before HFNC ≤ 169.2 was an independent predictor of HFNC failure. No apparent nosocomial infection occurred during the study period. Appropriate use of HFNC for acute respiratory failure caused by COVID-19 can reduce the severity of severe disease without causing nosocomial infection. Age, history of CKD, non-respiratory SOFA before HFNC ≤ 1, and SpO2/FiO2 before HFNC ≤ 169.2 were associated with HFNC failure.

Abstract
BACKGROUND A previous clinical trial for autoimmune pulmonary alveolar proteinosis (APAP) demonstrated that granulocyte-macrophage colony-stimulating factor (GM-CSF) inhalation reduced the mean density of the lung field on computed tomography (CT) across 18 axial slice planes at a two-dimensional level. In contrast, in this study, we challenged three-dimensional analysis for changes in CT density distribution using the same datasets. METHODS As a sub-study of the trial, CT data of 31 and 27 patients who received GM-CSF and placebo, respectively, were analyzed. To overcome the difference between various shooting conditions, a newly developed automatic lung field segmentation algorithm was applied to CT data to extract the whole lung volume, and the accuracy of the segmentation was evaluated by five pulmonary physicians independently. For normalization, the percent pixel (PP) in a certain density range was calculated as a percentage of the total number of pixels from -1,000 to 0 HU. RESULTS The automatically segmented images revealed that the lung field was accurately extracted except for 7 patients with minor deletion or addition. Using the change in PP from baseline to week 25 (ΔPP) as the vertical axis, we created a histogram with 143 HU bins set for each patient. The most significant difference in ΔPP between GM-CSF and placebo groups was observed in two ranges: from -1,000 to -857 and -143 to 0 HU. CONCLUSION Whole lung extraction followed by density histogram analysis of ΔPP may be an appropriate evaluation method for assessing CT improvement in APAP.

Abstract
INTRODUCTION This study aimed to evaluate the correlation and agreement between end-tidal CO2 (EtCO2 ) measured with the novel portable capnometer (CapnoEye®) and partial pressure of arterial carbon dioxide (PaCO2 ) levels in patients with respiratory diseases and to compare the efficacy of EtCO2 and PvCO2 in predicting PaCO2 levels. METHODS We analyzed the correlation and the agreement between EtCO2 and PaCO2 and between PvCO2 and PaCO2 using Pearson's moment correlation coefficient in patients with type 1 and type 2 respiratory failure and both groups overall. RESULTS A total of 100 samples were included that comprised 67 men (67%). The mean age of the subjects was 77 ± 13 years. Chronic obstructive pulmonary disease (COPD) (43%) was the most common disease. There was a high correlation between EtCO2 and PaCO2 (r = 0.88; p < 0.0001). Sixty-six PvCO2 samples were obtained, and there was a high correlation between PvCO2 and PaCO2 (r = 0.81; p < 0.0001). Regarding type 2 respiratory failure, there was a high correlation between EtCO2 and PaCO2 (r = 0.81). The Bland-Altman analysis between PaCO2 and EtCO2 revealed a bias of 5.7 mmHg, with limits of agreement ranging from -5.1 mmHg to 16.5 mmHg. In contrast, the analysis between PaCO2 and PvCO2 revealed a bias of -6.8 mmHg, and the limits of agreement ranged from -22.13 mmHg to 8.53 mmHg. CONCLUSION EtCO2 measured by CapnoEye® was significantly correlated to PaCO2 levels in patients with respiratory diseases. Moreover, CapnoEye® may be more useful for predicting hypercapnia conditions in which respiratory diseases are compared with measure PvCO2 .

Abstract
Thoracoscopy under local anaesthesia is effective for the diagnosis of tuberculous pleurisy (TP), mesothelioma and pleural metastases of lung cancer, etc. It has recently been reported that cryobiopsy is useful for obtaining sufficient tissue, achieving a greater depth, and avoiding crush artefact than biopsy forceps. However, the utility of the tissue obtained by cryobiopsy for culture for diagnosing TP is unknown. We compared positivity rates of tissue culture obtained by biopsy forceps and cryobiopsy in seven TP patients. The median tissue size was 2 mm by biopsy forceps and 6 mm by cryobiopsy. The pathological diagnostic rate of pleural tissue was 85.7% with biopsy forceps and 100% with cryobiopsy. However, the positivity rate of tissue culture was 57.1% with biopsy forceps and 28.5% with cryobiopsy. Since rapid freezing with a cryoprobe makes it difficult for bacteria to grow, it is possible that cryobiopsy might not be useful for obtaining a tissue culture in TP cases. However, since the sample size of this study was small, analysis of more cases is required to confirm our results.

Abstract
Bronchial artery embolization (BAE) is the first choice treatment for hemoptysis. With advances in endovascular treatment, various embolic materials have become available. However, the optimal embolic material for the treatment of cryptogenic hemoptysis has not been determined. This study aimed to investigate the short-and long-term efficacy of BAE using a gelatin sponge in the treatment of patients with cryptogenic hemoptysis. The clinical characteristics, angiographic findings, and short- and long-term outcomes of BAE were retrospectively analyzed in 22 consecutive patients who underwent BAE for control of cryptogenic hemoptysis between January 2010 and September 2018. Selective angiography and super-selective BAE were successfully performed for all patients. A gelatin sponge was used in all patients. Further, polyvinyl alcohol was mixed with the gelatin sponge in 11 patients (50%). Angiography showed that the bronchial artery was responsible for hemoptysis in all patients, along with the intercostal artery in one patient (4.5%) and the inferior phrenic artery in one patient (4.5%). Immediate hemostasis was achieved in all patients. The recurrence-free rate was 100% for 1 month, 94.1% for 3 months, 94.1% for 12 months, and 87.4% for 24 months. Of two patients with recurrent hemoptysis, one underwent bronchoscopic hemoptysis and the other received intravenous hemostatic agents. No patient underwent BAE for recurrence. No severe complications occurred. In conclusion, BAE using a gelatin sponge has short- and long-term hemostatic efficacy for treating cryptogenic hemoptysis without any severe complications. A gelatin sponge is a suitable embolic material for patients with cryptogenic hemoptysis.

Abstract
Pulmonary artery pseudoaneurysms (PAPs) are rare but can cause massive hemoptysis if they rupture. Infectious PAPs are often treated by surgery or transcatheter embolization and are rarely treated conservatively with antibiotics. We herein report a case of PAP treated conservatively in a 21-year-old woman with lung abscess. Except for one massive hemoptysis early in the course, the patient responded well to the empirical therapy with ampicillin/sulbactam and systemic hemostatic agents. After six weeks of antibiotics, the pseudoaneurysm disappeared. Conservative therapy with careful observation can be considered in small infectious PAPs when there is a good clinical response to initial conservative therapy.

Abstract
An 87-year-old woman who had undergone coil embolization 25 years ago for pulmonary arteriovenous fistula, which was diagnosed following repeated cerebral infarction, presented with massive hemoptysis. The coils migrated and were excreted in stool following hemoptysis during long-term follow-up. Although the technical success rate of coil embolization for pulmonary arteriovenous malformations is extremely high, and coil embolization-related complications are rare, little is known about the long-term complications. We herein report the clinical course of our case, review previous reports related to coil migration as a long-term complication, and discuss the associated mechanism.

Abstract
BACKGROUND Diffuse pulmonary ossification is a specific lung condition that is accompanied by underlying diseases. However, idiopathic dendriform pulmonary ossification (IDPO) is extremely rare, and the clinical features remain unclear. In this study, we aimed to report the clinical characteristics of IDPO. METHODS We conducted a nationwide survey of patients with IDPO from 2017 to 2019 in Japan and evaluated the clinical, radiological, and histopathological findings of patients diagnosed with IDPO. RESULTS Twenty-two cases of IDPO were identified. Most subjects (82%) were male, aged 22-56 years (mean (SD), 37.9 (9.1)) at diagnosis. Nearly 80% of the subjects were asymptomatic, and the condition was discovered during a medical check-up. However, 36% of the subjects showed a decline in forced vital capacity (%FVC) predicted <80% at diagnosis. The typical radiological features of high-resolution CT (HRCT) are calcified branching structures that are predominantly distributed in the lower lung fields without any other conspicuous finding. Histopathological analysis also showed dendriform ossified lesions from the intraluminal areas to interstitial areas. Notably, during the follow-up period of 20 years, disease progression was found in 88% on HRCT and more than 50% on pulmonary function tests (FVC and/or forced expiratory volume in 1 s). Two cases with rapid decline of 10% /year in %FVC predicted were observed.)) at diagnosis. Nearly 80% of the subjects were asymptomatic, and the condition was discovered during a medical check-up.

Abstract
BACKGROUND Polymyxin B-immobilized fiber column (PMX, Toraymyxin column) was approved for the relief of SIRS (systemic inflammatory response syndrome) caused by bacterial infection or endotoxemia. PMX reduces lung damage by removing leukocytes and cytokines in addition to endotoxin removal, in the setting of idiopathic pulmonary fibrosis. Acute exacerbation of interstitial pneumonia pathologically presents with diffuse alveolar damage (DAD). PMX direct hemoperfusion (PMX-DHP) demonstrated efficacy, improving oxygenation. SARS-CoV-2 virus causes COVID-19 pneumonia that emerged in December 2019. The condition may become severe about 1 week after onset, and respiratory failure rapidly develops, requiring intensive care management. A characteristic of COVID-19-related severe pneumonia is ground-glass opacities rapidly progressing in both lungs, which subsequently turn into infiltrative shadows. This condition could be classified as DAD. As for the congealing fibrinogenolysis system, D-dimer, fibrin/fibrinogen degradation product quantity and prolonged prothrombin time were significant factors in non-surviving COVID-19 cases, associated with aggravated pneumonia. Clinical trials are being conducted but, with the exception of remdesivir and dexamethasone, no treatments have yet been approved. COVID-19 aggravates with the deterioration of oxygen saturation, decrease in lymphocytes and the occurrence of an abnormal congealing fibrinogenolysis system, leading to diffuse lung damage. Once the condition transitions from moderate to severe, it is most necessary to prevent further exacerbation by providing treatment that will suppress the above symptoms as soon as possible. OBJECTIVE To acquire treatment options to prevent the transition from acute exacerbation of interstitial pneumonia to DAD. The mechanism of action envisioned for PMX-DHP is to reduce congealing fibrinogenolysis system abnormalities and increase oxygenation by removing activated leucocytes and cytokines, which are risk factors for the aggravation of COVID-19-related pneumonia. METHODS We will conduct a multicenter prospective intervention single-group study to evaluate the efficacy and safety of direct hemoperfusion using PMX-DHP for COVID-19 patients. Efficacy will be evaluated by the primary endpoint, which is the rate of Ordinal Scale for Clinical Improvement after PMX-DHP of at least 1 point from a status of 4.5.6 on Day 15. The effect of PMX-DHP will be estimated by setting a control group with background factors from non-PMX-DHP patients enrolled in the COVID-19 registry. This study will be carried out as a single-group open-label study and will be compared with a historical control. The historical control will be selected from the COVID-19 registry according to age, gender, and severity of pneumonia. RESULTS This study will help determine PMX-DHP treatment options in the medical setting by quickly collecting and publishing information on patient background and on the efficacy and safety of treatment by PMX-DHP. CONCLUSIONS From a clinical perspective, PMX-DHP is expected to become a first-line therapy to address unmet medical needs and prevent the exacerbation from moderate to severe ARDS (acute respiratory distress syndrome) in COVID-19 cases.

Abstract
Docetaxel is a cytotoxic taxane frequently used to treat patients with various cancers, including non‐small cell lung cancer (NSCLC). Docetaxel is known to cause acute myalgias, arthralgias, and neuropathy, but there have been few published case reports of myositis. Here, we describe a rare case of docetaxel‐induced myositis diagnosed based on laboratory data, thigh magnetic resonance imaging (MRI), and electromyography (EEG). A 66‐year‐old male was admitted for thigh pain and fatigue that onset 1 week prior. He had been diagnosed with stage IVA (cT4N0M1a) NSCLC 3 years ago and had been started on docetaxel (60 mg/m2 intravenously every 3 weeks; fourth‐line chemotherapy) 1 month earlier. After the second cycle, he developed both thigh pain and fatigue. On admission, his creatinine phosphokinase (CPK) level was elevated, thigh MRI revealed diffuse muscle edema, and EEG showed myogenic changes. We found no plausible cause for myositis except docetaxel. He was diagnosed with myositis and treated with oral prednisolone. His symptoms were relieved and the CPK level declined. Although rare, this case indicates that clinicians should consider the possibility of myositis as a complication in patients on docetaxel.

Abstract
The Pfizer-BioNTech mRNA vaccine (BNT162b2) is an effective and well-tolerated coronavirus disease 2019 (COVID-19) vaccine. However, rare adverse events have been reported. We report two cases of COVID-19 mRNA vaccine-related interstitial lung disease (ILD). A 67-year-old man and a 70-year-old man with underlying ILD presented to our hospital with a few days of fever and respiratory symptoms after receiving the BNT162b2 vaccine. Drug-related pneumonitis due to the COVID-19 mRNA vaccine was diagnosed. One case was diagnosed with lymphocytic alveolitis by bronchoalveolar lavage fluid and transbronchial lung cryobiopsy. Both patients were successfully treated with corticosteroids, and they attended outpatient clinics thereafter. Although the safety and efficacy of COVID-19 vaccines have been established, further studies are needed to estimate long-term data and reports of rare adverse reactions. We present the clinical course of two cases, review previously published case reports on COVID-19 mRNA vaccine-related ILD and discuss the relevant findings.

Abstract
A 33-year-old woman with a fever, cough, and pharyngitis was admitted after left-sided pleural effusion was detected. The fever and upper respiratory symptoms were confirmed, and she was diagnosed with coronavirus disease (COVID-19) after showing a positive polymerase chain reaction (PCR) test. After thoracentesis, pleural fluid revealed elevated adenosine deaminase values and a positive QuantiFeron test; tuberculous pleurisy was thus suspected. Subsequent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) PCR and anti-SARS-CoV-2 Spike IgG tests were negative, suggesting that the initial PCR result had been erroneous. However, we were unable to confirm this. Data concerning COVID-19 diagnostics are insufficient at present. It is important to make comprehensive judgments regarding the diagnosis and treatment of patients as well as public health.

Abstract
The outbreak of COVID-19 caused by infection with SARS-CoV-2 virus has become a worldwide pandemic, and the number of patients presenting with respiratory failure is rapidly increasing in Japan. An international meta-analysis has been conducted to identify genetic factors associated with the onset and severity of COVID-19, but these factors have yet to be fully clarified. Here, we carried out genomic analysis based on a genome-wide association study (GWAS) in Japanese COVID-19 patients to determine whether genetic factors reported to be associated with the onset or severity of COVID-19 in the international meta-GWAS are replicated in the Japanese population, and whether new genetic factors exist. Although no significant genome-wide association was detected in the Japanese GWAS, an integrated analysis with the international meta-GWAS identified for the first time the involvement of the IL17A/IL17F gene in the severity of COVID-19. Among nine genes reported in the international meta-GWAS as genes involved in the onset of COVID-19, the association of FOXP4-AS1, ABO, and IFNAR2 genes was replicated in the Japanese population. Moreover, combined analysis of ABO and FUT2 genotypes revealed that the presence of oral AB antigens was significantly associated with the onset of COVID-19. FOXP4-AS1 and IFNAR2 were also significantly associated in the integrated analysis of the Japanese GWAS and international meta-GWAS when compared with severe COVID-19 cases and the general population. This made it clear that these two genes were also involved in not only the onset but also the severity of COVID-19. In particular, FOXP4-AS1 was not found to be associated with the severity of COVID-19 in the international meta-GWAS, but an integrated analysis with the Japanese GWAS revealed an association with severity. Individuals with the SNP risk allele found between IL17A and IL17F had significantly lower mRNA expression levels of IL17F, suggesting that activation of the innate immune response by IL17F may play an important role in the severity of SARS-CoV-2 infection.

Abstract
OBJECTIVES The myositis-specific autoantibodies that characterise certain forms of idiopathic inflammatory myopathy (IIM) are useful for diagnosing dermatomyositis (DM) / polymyositis (PM) and predicting its prognosis. The autoantibody to phenylalanyl-tRNA synthetase (anti-Zo) has been identified as a disease marker antibody for anti-synthetase syndrome only in a UK cohort. Here we aim to establish an ELISA for the measurement of anti-Zo and to characterise the clinical features of Japanese patients who have this autoantibody. METHODS Anti-Zo was investigated by immunoprecipitation with recombinant phenylalanyl-tRNA synthetase α/β proteins. The results were confirmed by immunoprecipitation-Western blotting with cell extract. Sera from patients with DM/PM (n=224) were screened by an ELISA with the recombinant proteins. Medical records were retrospectively reviewed to obtain detailed information on the clinical phenotypes of the anti-Zo-positive patients. RESULTS Only two male patients were confirmed to have anti-Zo. Both patients had fever, myopathy, interstitial lung disease, and mechanic's hands, and these clinical features are consistent with those of anti-synthetase syndrome. Another patient's serum showed a higher level than the cut-off value for anti-phenylalanyl-tRNA synthetase α by our in-house ELISA, but was judged to be negative for anti-Zo by immunoprecipitation-Western blotting. CONCLUSIONS This is the first report of anti-Zo-positive IIM patients from Asia. Although Japanese patients with anti-Zo have a clinical phenotype similar to that of Caucasian patients, further large cohort studies are necessary to confirm the frequency of anti-Zo in Japanese IIM patients. Our newly developed ELISA should be validated for sensitivity and specificity in large cohorts.

Abstract
Genes of choline acetyltransferase (ChAT) and vesicular acetylcholine transporter are encoded in the same gene locus, called the cholinergic gene locus. They are essential in cholinergic neurons to maintain their functional phenotype. The genomic structure of the cholinergic gene locus is conserved among invertebrates to mammals. However, the cholinergic gene expression in a specific subset of neurons is unknown in insects except for Drosophila melanogaster. In this study, we analysed the upstream sequence of cholinergic gene locus in the silkworm Bombyx mori to identify specific cis-regulatory regions. We found multiple enhancer regions that are localized within 1 kb upstream of the cholinergic gene locus. The combination of promoter assays using small deletions and bioinformatic analysis among insect species illuminates two conserved sequences in the cis-regulatory region: TGACGTA and CCAAT, which are known as the cAMP response element and CAAT box, respectively. We found that dibutyryl-cAMP, an analogue of cAMP, influences the expression of ChAT in B. mori. Tissue-specific expression analysis of transcriptional factors identified potential candidates that control the cholinergic gene locus expression. Our investigation provides new insight into the regulation mechanism of cholinergic neuron-specific gene machinery in this lepidopteran insect.

Abstract
Bronchial thermoplasty (BT) is a type of bronchoscopic treatment specifically used for patients with severe asthma. Most severe asthmatics receive systemic steroids and are at risk of being immunocompromised. This raises the clinical question of whether or not BT can be effectively and safely performed in such patients. Herein, we report a case highlighting the effectiveness and safety of BT in a patient with severe persistent bronchial asthma and Pseudomonas aeruginosa infection. We performed BT on a 46-year-old woman undergoing treatment for severe persistent asthma with inhaled steroids and 20 mg prednisolone orally. Although she was deemed to be infection-free before the procedure, culture of endobronchial secretions obtained during the first BT procedure grew Pseudomonas aeruginosa. After the first BT, she was given clarithromycin 400 mg orally daily. The amount of sputum decreased with each BT session, and sputum culture for Pseudomonas aeruginosa turned negative by the third BT session. Respiratory function tests showed 23.7% improvement in % post-bronchodilator forced expiratory volume in 1.0 s (%FEV1.0) and the asthma quality of life questionnaire (AQLQ) score increased by 2.41 points after the third BT. Bronchial wall thickness decreased and infiltrative shadows on CT disappeared after the three BT sessions, along with decrease in the amount of purulent sputum. Improvement in her asthma symptoms, after three BT sessions allowed decrease in the prednisolone dose. We report the effectiveness of BT and infection control in a severe asthmatic with Pseudomonas aeruginosa infection. Bronchial thermoplasty (BT) is a type of bronchoscopic treatment specifically used for patients with severe asthma. There is a clinical question that whether we can perform the BT effectively and safely on immunocompromised patients. We report the effectiveness of BT and infection control in a severe asthmatic with Pseudomonas aeruginosa infection.

Abstract
Background Coronavirus disease 2019 (COVID-19), which is caused by severe acute respiratory syndrome coronavirus 2, has been a significant concern worldwide since its outbreak in December 2019. Various treatments are being researched and developed, and there are reports that dexamethasone has reduced the mortality rate and improved the clinical course of critically ill patients with COVID-19. In this study, we examined the clinical efficacy of corticosteroid therapy for patients with COVID-19 in our hospital during the first wave of infections. Methods We retrospectively reviewed the medical records of patients with COVID-19 who were treated with or without corticosteroid therapy at the National Center for Global Health and Medicine in Japan between February and April 2020. The primary outcome was improvement in the patients’ clinical course using a seven-category ordinal scale. We collected data on patient characteristics, treatment, and clinical course, and compared them between two groups: the steroid-using group and the non-steroid-using group. Results Between February and April 2020, 110 patients were diagnosed with COVID-19. Despite poor conditions during admission into the steroid group, there were no statistical differences in clinical course between both groups, as measured using the scale. There were no statistical differences between the two groups in the number of days to fever resolution or negative polymerase chain reaction results. Conclusions There was no difference in the clinical course between both groups. Because of the difference in background, corticosteroids may potentially make the clinical course of severely ill patients similar to that of mildly ill patients.

Abstract
Bronchoscopy is a procedure for diagnosis and treatment decision-making in patients with lung disease, especially those with acute respiratory failure. However, the optimal bronchoscopic method for patients with acute respiratory failure is not known. Therefore, in the real world, we sometimes hesitate to perform bronchoscopy in such patients because of safety and have experienced treating patients without bronchoscopy. To address this problem, we evaluated the usefulness and safety of Jackson mask ventilation, a novel noninvasive method of bronchoscopy performed under mask ventilation using the Jackson Rees circuit, in patients with acute respiratory failure.We retrospectively reviewed patients with acute respiratory failure who underwent bronchoscopy at our institution between January 2015 and May 2018. We compared patients who received Jackson mask ventilation (Jackson group) and those who received conventional oxygen administration (conventional group). Mean percutaneous oxygen saturation (SpO2) and mean oxygen flow rate were compared between the groups by the Wilcoxon signed-rank test. We excluded patients who were intubated and those without acute respiratory failure who received Jackson mask ventilation preventively.Of 1262 patients who underwent bronchoscopy, 12 were classified into the Jackson group and 13 into the conventional group. Proper oxygenation was maintained in the Jackson group, with SpO2 increasing after Jackson mask ventilation (89.4% to 96.8%, P = .03). Mean SpO2 was significantly higher in the Jackson group than in the conventional group (96.8% vs 95.2%, P = .03). Mean oxygen flow rate was significantly lower in the Jackson group (4.0 L/min vs 7.9 L/min, P < .001). There was no significant difference in safety.Our findings suggest that Jackson mask ventilation is safe and effective when performing bronchoscopy in patients with acute respiratory failure. Jackson mask ventilation maintained proper oxygenation and decreased the oxygen flow rate compared with the conventional method. Using Jackson mask ventilation, we could perform bronchoscopy safely and effectively in patients with acute respiratory failure, including some who had unstable respiratory status. (UMIN000038481).

Abstract
OBJECTIVES To alleviate the overflow of coronavirus disease 2019 (COVID-19) patients in hospitals, less invasive and simple criteria are required to triage the patients. We evaluated the relationship between COVID-19 severity and fatty liver on plain computed tomography (CT) scan performed on admission. METHODS In this retrospective cohort study, we considered all COVID-19 patients at a large tertiary care hospital between January 31 and August 31, 2020. COVID-19 severity was categorized into severe (moderate and severe) and non-severe (asymptomatic and mild) groups, based on the Japanese National COVID-19 guidelines. Fatty liver was detected on plain CT scan. Multivariate logistic regression analysis was performed to evaluate factors associated with severe COVID-19. RESULTS Of 222 patients (median age: 52 years), 3.2%, 58.1%, 20.7%, and 18.0% presented with asymptomatic, mild, moderate, and severe COVID-19, respectively. Although 59.9% had no fatty liver on plain CT, mild, moderate, and severe fatty liver occurred in 13.1%, 18.9%, and 8.1%, respectively. Age and presence of fatty liver were significantly associated with severe COVID-19. CONCLUSION Our study showed that fatty liver on plain CT scan on admission can become a risk factor for severe COVID-19. This finding may help clinicians to easily triage COVID-19 patients.

Abstract
We herein report a 48-year-old man with a history of chronic atrial fibrillation (AF) and repeated hemoptysis after radiofrequency ablation. Contrast tomography showed soft tissue thickening of the left hilar region and left pulmonary vein stenosis. We performed bronchial artery embolization, but the hemoptysis did not disappear, and AF was not controlled. We performed left lung lobectomy and maze procedures since we considered surgical removal necessary as radical treatment. After the surgery, hemoptysis and atrial fibrillation did not recur. Refractory hemoptysis after catheter ablation is rare, but occasionally occurs in patients with severe pulmonary vein stenosis.

Abstract
Introduction The administration of systemic corticosteroids is a key strategy for improving COVID-19 outcomes. However, evidence is lacking on combination therapies of antiviral agents and systemic corticosteroids. The objective of this study was to investigate the efficacy and safety of the combination therapy of favipiravir and methylprednisolone in preventing respiratory failure progression in patients with COVID-19 and non-critical respiratory failure. Methods We conducted a multicenter, open-label, single-arm phase II study. The patients received favipiravir 3600 mg on the first day, followed by 1600 mg for a total of 10–14 days. Methylprednisolone was administered intravenously at 1 mg/ideal body weight (IBW)/day from days 1 to 5, followed by 0.5 mg/IBW/day from days 6 to 10 if clinically indicated. The primary endpoint was the proportion of patients requiring mechanical ventilation (MV) (including noninvasive positive pressure ventilation) or those who met the criteria for tracheal intubation within 14 days of the study treatment initiation (MVCTI-14). Results Sixty-nine patients were enrolled and underwent the study treatment. Of them, the MVCTI-14 proportion was 29.2% (90% confidence interval 20.1–39.9, p = 0.200). The proportion of patients who required MV or who died within 30 days was 26.2%, and 30-day mortality was 4.9%. The most significant risk factor for MVCTI-14 was a smoking history (odds ratio 4.1, 95% confidence interval 1.2–14.2). The most common grade 3–4 treatment-related adverse event was hyperglycemia, which was observed in 21.7%. Conclusion The MVCTI-14 proportion did not reach a favorable level in the clinical trial setting with the threshold of 35%. However, the proportion of MV or death within 30 days was 26.6%, which might be close to the findings (28.1%) of the RECOVERY trial, which showed the efficacy of dexamethasone for patients with COVID-19 and non-critical respiratory failure. Further evaluation of this combination therapy is needed. Clinical Trial Registration Japan Registry of Clinical Trials (jRCT) identifier jRCTs041200025.

Abstract
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.

Abstract
We herein report a 67-year-old kidney transplant patient who died of COVID-19. He was treated with hydroxychloroquine and azithromycin and received mechanical ventilation that temporarily improved his respiratory status. Despite our efforts, however, he later developed respiratory failure and died 43 days after the disease onset. The autopsy revealed prominent organization of alveoli and alveolar ducts, with a massive accumulation of macrophages in the lungs. A few severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antigen-positive cells were detected in the lung, suggesting delayed virus clearance owing to his long-term immunosuppressed state, leading to constant lung damage and ultimately respiratory failure.

Abstract
The aim of this study was to describe the clinical and radiological findings of COVID-19 patients with “silent hypoxia,” who had no dyspnea on admission even though their oximetry saturation was less than 94%. This retrospective cohort study included all COVID-19 patients (n = 270) at a large tertiary care hospital between January 31 and August 31, 2020. Clinical and radiological characteristics of patients who met our criteria of “silent hypoxia”, which included those who reported no dyspnea even though oximetry saturation was <94%, were extracted. Eight patients (3.0%) met the criteria for “silent hypoxia.” The median age was 61 years (interquartile range [IQR]: 48.8–72.3), and five (62.5%) were men. All patients had consolidation on CT and showed a moderate to high COVID-19 CT severity score (median: 13.5, IQR: 10.8–15.3). The median FIO2 of the maximum oxygen required was 55 (IQR: 28–70)%. Two patients (25.0%) were intubated, and one patient (12.5%) underwent extracorporeal membrane oxygenation. Some COVID-19 patients with “silent hypoxia” may develop severe disease. Close and accurate monitoring of patients using arterial blood gas and pulse oximetry is necessary, regardless of their symptoms.

Abstract
Corticosteroids use in coronavirus disease 2019 (COVID-19) is controversial, especially in mild to severe patients who do not require invasive/noninvasive ventilation. Moreover, many factors remain unclear regarding the appropriate use of corticosteroids for COVID-19. In this context, this multicenter, retrospective, propensity score-matched study was launched to evaluate the efficacy of systemic corticosteroid administration for hospitalized patients with COVID-19 ranging in the degree of severity from mild to critically-ill disease. This multicenter, retrospective study enrolled consecutive hospitalized COVID-19 patients diagnosed January-April 2020 across 30 institutions in Japan. Clinical outcomes were compared for COVID-19 patients who received or did not receive corticosteroids, after adjusting for propensity scores. The primary endpoint was the odds ratio (OR) for improvement on a 7-point ordinal score on Day 15. Of 1092 COVID-19 patients analyzed, 118 patients were assigned to either the corticosteroid and non-corticosteroid group, after propensity score matching. At baseline, most patients did not require invasive/noninvasive ventilation (85.6% corticosteroid group vs. 89.8% non-corticosteroid group). The odds of improvement in a 7-point ordinal score on Day 15 was significantly lower for the corticosteroid versus non-corticosteroid group (OR, 0.611; 95% confidence interval [CI], 0.388-0.962; p = 0.034). The time to improvement in radiological findings was significantly shorter in the corticosteroid versus non-corticosteroid group (hazard ratio [HR], 1.758; 95% CI, 1.323-2.337; p < 0.001), regardless of baseline clinical status. The duration of invasive mechanical ventilation was shorter in corticosteroid versus non-corticosteroid group (HR, 1.466; 95% CI, 0.841-2.554; p = 0.177). Of the 106 patients who received methylprednisolone, the duration of invasive mechanical ventilation was significantly shorter in the pulse/semi-pulse versus standard dose group (HR, 2.831; 95% CI, 1.347-5.950; p = 0.006). In conclusion, corticosteroids for hospitalized patients with COVID-19 did not improve clinical status on Day 15, but reduced the time to improvement in radiological findings for all patients regardless of disease severity and also reduced the duration of invasive mechanical ventilation in patients who required intubation.Trial registration: This study was registered in the University hospital Medical Information Network Clinical Trials Registry on April 21, 2020 (ID: UMIN000040211).

Abstract
BACKGROUND Phase IV clinical trials in Western countries have reported that combined therapy with pirfenidone and nintedanib for idiopathic pulmonary fibrosis (IPF) has a manageable safety profile. However, data on the long-term safety and tolerability of this combination treatment in the real-world setting in Japan are limited. METHODS The retrospective data of 46 patients with IPF who received combination therapy with pirfenidone and nintedanib were obtained from 16 institutes in Japan. Adverse events and adverse drug reactions (ADRs) were reported through a retrospective review of medical records. RESULTS Nintedanib and pirfenidone were added to preceding treatment with antifibrotic drugs in 32 (69.6%) and 13 (28.3%) patients, respectively. In one patient (2.1%), the two drugs were concurrently initiated. The mean duration of monotherapy before initiating the combination was 26.3 months. In 26 of 38 patients (68.4%), the Gender-Age-Physiology index stage was II or III. Thirty-three patients (71.7%) had some ADRs, and 14 patients (30.4%) permanently discontinued either drug or both drugs owing to the development of ADRs during the observation period (mean: 59 weeks). The percentage of grade III or IV IPF according to the Japanese Respiratory Society severity classification was higher in patients who permanently discontinued either drug or both drugs than in those who continued both drugs (90.9% [10/11; 3 undetermined grade] vs. 61.1% [11/18; 1 undetermined grade]). Decreased appetite (18/46, 39.1%) and diarrhea (16/46, 34.8%) were frequently observed ADRs. Two patients (4.3%) had serious ADRs (liver toxicity and pneumothorax). CONCLUSIONS Real-world data imply that combination therapy with pirfenidone and nintedanib for IPF has a manageable safety/tolerability profile.

Abstract
Coronavirus disease (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) originating in Wuhan, China, has spread globally very rapidly. The number of COVID-19 patients increased in Japan from late March to early April 2020. Since COVID-19 treatment methods with antiviral drugs were not established in March 2020, clinical trials began at a rapid pace worldwide. We participated in a global investigator-initiated clinical trial of the antiviral drug remdesivir. It took approximately two months to prepare for and start patient enrollment, 26 days to enroll all patients in Japan, and 32 days from the end of enrollment to the release of the first report, a fairly quick response overall. In the course of this clinical trial, we found some of the critical issues related to conducting an infectious disease clinical trial in Japan need to be addressed and tackled to support a rapid response. These included such things as the necessity of a research network to promote clinical research, a framework for a rapid review system of clinical trial notification, and better cooperation with outsourced teams. Furthermore, for Japan to take the lead in global collaborative research and development in the field of infectious diseases, it is necessary to develop further human resources and organization on a national basis. It is indispensable for Japan to establish a clinical trial system at the national level to prepare for future emerging and re-emerging infectious diseases.

Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus causing coronavirus disease 2019 (COVID-19) was announced as an outbreak by the World Health Organization (WHO) in January 2020 and as a pandemic in March 2020. The majority of infected individuals have experienced no or only mild symptoms, ranging from fully asymptomatic cases to mild pneumonic disease. However, a minority of infected individuals develop severe respiratory symptoms. The objective of this study was to identify susceptible HLA alleles and clinical markers that can be used in risk prediction model for the early identification of severe COVID-19 among hospitalized COVID-19 patients. A total of 137 patients with mild COVID-19 (mCOVID-19) and 53 patients with severe COVID-19 (sCOVID-19) were recruited from the Center Hospital of the National Center for Global Health and Medicine (NCGM), Tokyo, Japan for the period of February–August 2020. High-resolution sequencing-based typing for eight HLA genes was performed using next-generation sequencing. In the HLA association studies, HLA-A*11:01:01:01 [Pc = 0.013, OR = 2.26 (1.27–3.91)] and HLA-C*12:02:02:01-HLA-B*52:01:01:02 [Pc = 0.020, OR = 2.25 (1.24–3.92)] were found to be significantly associated with the severity of COVID-19. After multivariate analysis controlling for other confounding factors and comorbidities, HLA-A*11:01:01:01 [P = 3.34E-03, OR = 3.41 (1.50–7.73)], age at diagnosis [P = 1.29E-02, OR = 1.04 (1.01–1.07)] and sex at birth [P = 8.88E-03, OR = 2.92 (1.31–6.54)] remained significant. The area under the curve of the risk prediction model utilizing HLA-A*11:01:01:01, age at diagnosis, and sex at birth was 0.772, with sensitivity of 0.715 and specificity of 0.717. To the best of our knowledge, this is the first article that describes associations of HLA alleles with COVID-19 at the 4-field (highest) resolution level. Early identification of potential sCOVID-19 could help clinicians prioritize medical utility and significantly decrease mortality from COVID-19.

Abstract
Background The current gold standard in coronavirus disease (COVID-19) diagnostics is the real-time reverse transcription–polymerase chain reaction (RT-PCR) assay for detecting severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RNA in nasopharyngeal swab (NPS) samples. Alternatively, nasal swab (NS) or saliva swab (SS) specimens are used, although available data on test accuracy are limited. We examined the diagnostic accuracy of NPS/NS/SS samples for this purpose. Methods Ten patients were included after being tested positive for SARS-CoV-2 RT-PCR in NPS samples according to the National Institute of Infectious Disease guidelines. In comparison with this conventional diagnostic method, NPS/NS/SS samples were tested using the cobas 6800 systems RT-PCR device. To investigate the usefulness of the cobas method and the difference among sample types, the agreement and sensitivity were calculated. Five to six samples were collected over a total period of 5–6 d from each patient. Results Fifty-seven sets of NPS/NS/SS samples were collected, of which 40 tested positive for COVID-19 by the conventional method. Overall, the concordance rates using the conventional method were 86.0%/70.2%/54.4% for NPS/NS/SS samples (cobas); however, for samples collected up to and including on Day 9 after disease onset (22 negative and one positive specimens), the corresponding rates were 95.7%/87.0%/65.2%. The overall sensitivity estimates were 100.0%/67.5%/37.5% for NPS/NS/SS samples (cobas). For samples up to 9 d after onset, the corresponding values were 100.0%/86.4%/63.6%. Conclusions NS samples are more reliable than SS samples and can be an alternative to NPS samples. They can be a useful diagnostic method in the future.

Abstract
COVID-19, a novel coronavirus-related illness, has spread worldwide. Patients with apparently mild/moderate symptoms can suddenly develop severe pneumonia. Therefore, almost all COVID-19 patients require hospitalization, which can reduce limited medical resources in addition to overwhelming medical facilities. To identify predictive markers for the development of severe pneumonia, a comprehensive analysis of serum chemokines and cytokines was conducted using serial serum samples from COVID-19 patients. The expression profiles were analyzed along the time axis. Serum samples of common diseases were enrolled from a BioBank to confirm the usefulness of predictive markers. Five factors, IFN-λ3, IL-6, IP-10, CXCL9, and CCL17, were identified as predicting the onset of severe/critical symptoms. The factors were classified into two categories. Category A included IFN-λ3, IL-6, IP-10, and CXCL9, and their values surged and decreased rapidly before the onset of severe pneumonia. Category B included CCL17, which provided complete separation between the mild/moderate and the severe/critical groups at an early phase of SARS-CoV-2 infection. The five markers provided a high predictive value (area under the receiver operating characteristic curve (AUROC): 0.9-1.0, p < 0.001). Low expression of CCL17 was specifically observed in pre-severe COVID-19 patients compared with other common diseases, and the predictive ability of CCL17 was confirmed in validation samples of COVID-19. The factors identified could be promising prognostic markers to distinguish between mild/moderate and severe/critical patients, enabling triage at an early phase of infection, thus avoiding overwhelming medical facilities.

Abstract
Bronchial thermoplasty (BT) is an interventional endoscopic treatment for severe bronchial asthma. Some studies have shown the clinical efficacy of this intervention, but its cost-effectiveness is unclear. The aim of this study was to evaluate the cost-effectiveness of BT. We collected data from the medical records of 16 Japanese patients who were treated with BT between February 2015 and April 2017, and compared asthma-related medical expenses between the year preceding and the year following BT. Four patients were Global Initiative for Asthma (GINA) treatment step 4, and 12 were step 5. In 8 patients who had a successful response to BT, the annual asthma-related medical expenses decreased because of a reduction in hospitalization and emergency outpatient visits due to asthma attacks, and termination of the use of biologics. Most patients in the non-responder group had increased asthma-related medical costs postoperatively. The main reason for the increase in medical costs was the add-on treatment of biologics. BT was cost-effective in the responder group. If its effects continue for more than 10 years, BT will be a cost-effective treatment. Medical costs will be reduced if those who respond to BT can be identified prior to commencement of treatment.

Abstract
Objective To evaluate the efficacy and safety of direct hemoperfusion using a polymyxin B‐immobilized polystyrene column (PMX‐DHP) in severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2)‐positive pneumonia patients. Methods This study was a case series conducted at a designated infectious diseases hospital. Twelve SARS‐CoV‐2‐positive patients with partial pressure of arterial oxygen/percentage of inspired oxygen (P/F) ratio < 300 were treated with PMX‐DHP on two consecutive days each during hospitalization. We defined day 1 as the first day when PMX‐DHP was performed. PMX‐DHP efficacy was assessed on days 7 and 14 after the first treatment based on eight categories. Subsequently, improvement in P/F ratio and urinary biomarkers on days 4 and 8, malfunctions, and ventilator and extracorporeal membrane oxygenation avoidance rates were also evaluated. Results On day 14 after the first treatment, disease severity decreased in 58.3% of the patients. P/F ratio increased while urine β2‐microglobulin decreased on days 4 and 8. Cytokine measurement pre‐ and post‐PMX‐DHP revealed decreased levels of interleukin‐6 and the factors involved in vascular endothelial injury, including vascular endothelial growth factor. Twenty‐two PMX‐DHPs were performed, of which seven and five PMX‐DHPs led to increased inlet pressure and membrane coagulation, respectively. When the membranes coagulated, the circuitry needed to be reconfigured. Circuit problems were usually observed when D‐dimer and fibrin degradation product levels were high before PMX‐DHP. Conclusions Future studies are expected to determine the therapeutic effect of PMX‐DHP on COVID‐19. Because of the relatively high risk of circuit coagulation, coagulation capacity should be assessed beforehand.

Abstract
Coronavirus disease (COVID-19) is associated with pulmonary hypertension due to pulmonary
embolism, which affects subsequent outcomes. However, definitive diagnosis of pulmonary
hypertension is difficult because of the risk of spreading the infection. Here, we assess
the utility of plane computed tomography in noninvasively predicting the clinical severity
of COVID-19.

Abstract
Diffuse pulmonary lymphangiomatosis (DPL) is a rare lymphatic disease that can cause diverse respiratory symptoms. A 22-year-old man, whose chest CT had shown an abnormality for years, presented with acute respiratory failure due to the abrupt onset of hemoptysis. The diagnosis of DPL was confirmed by surgical lung biopsy and lymphangiography. Histopathological investigation showed dilated vascular and lymphatic vessels. DPL can cause acute and life-threatening symptoms during its chronic clinical course. A coexisting anomaly in the venous system may be present in DPL patients with hemoptysis.

Abstract
Background Osimertinib, a third-generation epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitor (TKI), can be used as second-line treatment for lung cancer patients harboring the T790M substitution. Although osimertinib is more effective than the first-generation EGFR-TKIs used for first-line treatment, its efficacy with respect to long-term patient survival remains unclear even upon the administration of a complete sequence of EGFR-TKI therapy. Moreover, limited information is available regarding genetic diagnostic approaches after the treatment of EGFR-TKI–naïve patients. This study investigated the clinical characteristics of EGFR-mutated lung cancer patients harboring the T790M substitution resistant to EGFR-TKIs, as well as the advantages of rebiopsy and liquid biopsy for these patients. Methods The medical records of patients screened for EGFR mutations were reviewed. Upon failure of naïve treatment with EGFR-TKIs, except for osimertinib, single-plexus cobas version 2 was repeatedly used to detect the T790M substitution in EGFR via tissue or liquid biopsy. Results From April 2016 through May 2019, 113 patients were found to harbor EGFR mutations. Sixty patients were treated with EGFR-TKIs, among whom 46 underwent tissue or liquid biopsy. Twenty-nine of these 46 (63%) patients harbored the T790M substitution. In total, 141 rebiopsies were performed. The T790M substitution was detected in 24 of 43 tissue biopsies and 11 of 98 liquid biopsies. If patients displayed an EGFR exon 19 deletion, had a new lesion, and were administered gefitinib as first-line therapy, they were suspected to harbor the T790M substitution. Furthermore, the T790M substitution was detected through rebiopsy in patients with coexisting original mutations, brain metastases, tumor enlargement by ≥12 mm, or metastases at minor sites. Conclusion Among patients with positive factors associated with the T790M mutation, repeated tissue or liquid biopsies are useful to maximize the detection rate of the T790M substitution. Furthermore, these biopsies need to be repeated numerous times in order to reduce “detection overlook” among such patients.
