BACKGROUND AND DESIGN: The coronavirus disease (COVID-19) pandemic is having a devastating effect worldwide. Host genome differences between populations may influence the severity of COVID-19. The Japan COVID-19 Task Force is conducting host genome analysis of hospitalized patients with COVID-19 from more than 70 institutions nationwide in Japan. This report describes the clinical characteristics of patients enrolled to date. RESULTS: The median (interquartile range) age of the 1674 patients included in the analysis was 59 (45-71) years, and more than half of the patients (66.2%) were male. Less than half of the patients (41.2%) had severe disease. The case fatality rate was 3.2%. CONCLUSIONS: Since this is a hospital-based study, the number of severe cases was relatively high, but the case fatality rate was relatively low, when compared to that of other countries. In the future, we will continue to enroll patients and conduct genome analyses of patients with COVID-19.

Modern Rheumatology 32 (6), 1153-1162 32 （ 6 ） 1153 - 1162 2021年11月

ISSN 1439-7595

OBJECTIVE: This study aimed to determine the clinical efficacy of apremilast for oral ulcers, extra-oral manifestations, and overall disease activity in patients with Behçet's disease (BD). METHODS: A systematic literature search was performed in PubMed, EMBASE, Cochrane Library, and Web of Science Core Collection. Studies assessing the treatment effects of apremilast in BD were included. The odds ratios (ORs) of being symptom free for individual manifestations and mean difference (MD) of Behçet's Disease Current Activity Form (BDCAF) scores were calculated with 95% confidence intervals (CIs) at 12 and 24 weeks using a random-model meta-analysis. RESULTS: Of 259 screened articles, eight were included. After 12 weeks of apremilast treatment the OR of symptom-free was as followings: oral ulcers, 45.76 (95% CI, 13.23-158.31); genital ulcers, 4.56 (95% CI, 2.47-8.44); erythema nodosum, 3.59 (95% CI, 1.11-11.61); pseudofolliculitis, 2.81 (95% CI, 1.29-6.15); and arthritis, 3.55 (95% CI, 1.71-7.40). Furthermore, BDCAF scores at 12 weeks were significantly reduced (MD=-1.38; -1.78 to -0.99). However, the proportion of oral-ulcer free patients increased at 24 weeks (OR=14.88; 4.81 to 46.07). CONCLUSION: The currently accumulated data indicates an improvement in mucocutaneous and articular symptoms by short-term apremilast treatment in patients with BD.

K Nakagawara, H Namkoong, H Terai, K Masaki, T Tanosaki, ...

BMJ Open Respiratory Research 8 (1), e001015 8 （ 1 ） 2021年11月

INTRODUCTION: The rapid spread of COVID-19 posed a global burden. Substantial number of people died of the disease in the acute phase of infection. In addition, a significant proportion of patients have been reported to suffer from post-acute phase symptoms, sequelae of COVID-19, which may negatively influence the quality of daily living and/or socioeconomic circumstances of the patients. However, no previous study has comprehensively and objectively assessed the quality of life of patients by using existing international scales. Further, evidence of socioeconomic consequences among patients with COVID-19 is scarce. To address the multidimensional issues from sequelae of COVID-19, evidence from comprehensive surveys beyond clinical perspectives is critical that investigates health, and social determinants of disease progression as well as socioeconomic consequences at a large scale. METHODS AND ANALYSIS: In this study, we plan to conduct a nationwide and comprehensive survey for the sequelae of COVID-19 in a total of 1000 patients diagnosed at 27 hospitals throughout Japan. This study will evaluate not only the health-related status of patients from clinical perspectives but also the Health-related Quality of Life (HRQoL) scores, socioeconomic status and consequences to discuss the sequelae of the disease and the related risk factors. The primary endpoint is the frequency of long-term complications of COVID-19 infection. The secondary endpoints are risk factors for progression to sequelae of COVID-19 infection. The study will provide robust and important evidence as a resource to tackle the issues from the sequelae of COVID-19 from the multi-dimensional perspectives. ETHICS AND DISSEMINATION: This trial was approved by the Keio University School of Medicine Ethics Committee (20200243, UMIN000042299). The results of this study will be reported at a society meeting or published in a peer-reviewed journal.

Cardiac tamponade due to primary malignant pericardial mesothelioma diagnosed with surgical pericardial resection

N Kawakami, M Kawai, H Namkoong, D Arai, S Ueda, K Hamada, ...

Journal of Cardiology Cases 24 (4), 149-152 24 （ 4 ） 149 - 152 2021年10月

Primary malignant pericardial mesothelioma is an extremely rare disease. Malignant disease of the pericardium is an infrequent cause of cardiac tamponade. Hence, cardiac tamponade in the context of primary malignant mesothelioma of the pericardium is an uncommon clinical scenario. A 67-year-old male patient, an ex-smoker, complaining of progressive lethargy was referred to a hospital for investigation of persistent pericardial effusion. The pericardial fluid cytology was categorized as class Ⅲ. Thereafter, he was referred to our hospital for further evaluation. Fluorodeoxyglucose (FDG) positron emission tomography (PET) revealed FDG accumulation in the pericardium and mediastinal lymph node. Surgical biopsy of the pericardium was performed through a subxiphoid approach for a definitive diagnosis. Histopathological examination revealed diffuse infiltration of the pericardium by a malignant tumor consisting of epithelioid cells with large round nuclei and prominent nucleoli, arranged in a tubular papillary pattern. Finally, the patient was diagnosed with primary malignant pericardial mesothelioma of epithelioid type. The patient died 6 weeks after admission. This diagnosis must be considered in patients having unexplained massive pericardial effusion. Furthermore, we should consider prompt cytological analysis and FDG PET to arrive rapidly at a definitive diagnosis to administer combination chemotherapy that may provide clinical benefit. <Learning objective: Primary malignant pericardial mesothelioma is a rare disease.

The influenza virus infection poses a serious health threat worldwide. Myeloid cells play pivotal roles in regulating innate and adaptive immune defense. A disintegrin and metalloproteinase (ADAM) family of proteins contribute to various immune responses; however, the role of ADAM10 in influenza virus infection remains largely unknown. Herein, we investigated its role, focusing on myeloid cells, during influenza virus infection in mice. Adam10flox/flox/Lyz2-Cre (Adam10ΔLyz2) and control Adam10flox/flox mice were intranasally infected with 200 plaque-forming units of influenza virus A/H1N1/PR8/34. Adam10ΔLyz2 mice exhibited a significantly higher mortality rate, stronger lung inflammation, and a higher virus titer in the lungs than control mice. Macrophages and inflammatory cytokines such as TNF-α, IL-1b, and CCL2 were increased in bronchoalveolar lavage fluid from Adam10ΔLyz2 mice following infection. CD11b+Ly6G-F4/80+ myeloid cells, which had an inflammatory monocytes/macrophages-like phenotype, were significantly increased in the lungs of Adam10ΔLyz2 mice. Adoptive transfer experiments suggested that these cells likely contributed to the poorer prognosis in Adam10ΔLyz2 mice. Seven days after infection, CD11b+Ly6G-F4/80+ lung cells exhibited significantly higher arginase-1 expression levels in Adam10ΔLyz2 mice than in control mice, while an arginase-1 inhibitor improved the prognosis of Adam10ΔLyz2 mice. Enhanced granulocyte-macrophage colony-stimulating factor (GM-CSF)/GM-CSF receptor signaling likely contributed to this process. Collectively, these results indicate that myeloid ADAM10 protects against influenza virus pneumonia and may be a promising therapeutic target.

H Takei, N Nishina, H Namkoong, K Suzuki, Y Uwamino, N Hasegawa, ...

Modern rheumatology 32 (3), 534-540 32 （ 3 ） 534 - 540 2021年08月

ISSN 1439-7595

OBJECTIVES: Nontuberculous mycobacterial pulmonary disease (NTM-PD) is a rare but important comorbidity of rheumatoid arthritis (RA). Our objective was to investigate the association between NTM-PD and RA, especially regarding the immunosuppressive treatment of RA such as biological disease-modifying antirheumatic drugs (bDMARDs). METHODS: We conducted a retrospective, single-centre cohort study. All RA patients regularly followed up at our rheumatology division in December 2012 were included in the study, and followed for 5 years. RESULTS: At baseline, 26 of 1639 RA patients had NTM-PD. During the observation period, 14 were newly diagnosed with NTM-PD. For new diagnosis of NTM-PD, bDMARD use at baseline was not a significant risk factor. Among the 40 patients with NTM-PD, 16 were treated with a total of 27 bDMARDs after NTM-PD diagnosis. They did not present with a greater exacerbation of NTM-PD than those not treated with bDMARDs (25 vs. 17%, p = .52). A total of 55 patients died, but nobody died of NTM-PD. NTM-PD was not associated with worse mortality in multivariate analysis (hazard ratio, 2.0; 95% CI, 0.6-6.4; p = .26). CONCLUSIONS: Biological DMARD was not associated with worse prognosis of NTM-PD. Careful use of bDMARDs could be tolerated in RA patients with NTM-PD.

TRANSLATIONAL LUNG CANCER RESEARCH 10 （ 8 ） 3550 - 3566 2021年08月

ISSN 2218-6751

Background: Non-small cell lung cancer (NSCLC) is the leading cause of cancer-related death worldwide. There is a rank order of the efficacy and safety of treatment options, including immune checkpoint inhibitors (ICIs), bevacizumab (Bev), and cytotoxic drugs. When patients have low programmed death-ligand 1 (PD-L1) expression, there are multiple options for treatment. In this study, we focused on ICI regimens in patients with non-squamous NSCLC with low PD-L1 expression and no driver alterations and assessed the efficacy of the regimens using network meta-analysis. Methods: Randomized trials for incurable chemo-naïve non-squamous NSCLC were collected through electronic searches. The data were independently extracted and cross-checked by two investigators. The primary outcome of this analysis was overall survival (OS). A frequentist weighted least-squares approach random-model network meta-analysis was applied. Results: Sixty-eight eligible studies and 22,619 patients were identified. Using a platinum + third-generation cytotoxic agent regimen (platinum regimen) as a reference, the platinum regimen + pembrolizumab (Pemb) [hazard ratio (HR) =0.55, 95% confidence interval (CI): 0.34-0.89, P=0.015] showed the best OS, followed by the platinum regimen + nivolumab (Niv) + ipilimumab (Ipi) (HR =0.61, 95% CI: 0.44-0.84, P=0.003) with no heterogeneity (I2=0%, P=0.348). Conclusions: The addition of Pemb or Niv/Ipi to platinum-based chemotherapy seems to be a good therapeutic option for non-squamous NSCLC with a PD-L1 tumor proportion score (TPS) of 1-49%.

We performed this study to provide the latest evidence of the diagnostic accuracy of all Aspergillus antibodies for chronic pulmonary aspergillosis (CPA). In this meta-analysis, we searched the Cochrane Central Register of Controlled Trials, MEDLINE, Embase, and other databases, until 19 March 2020, for studies that examined the diagnostic accuracy of each Aspergillus-specific antibody for CPA and assessed the risk of bias using the revised Quality Assessment of Diagnostic Accuracy Studies-2 tool. We integrated the results using a hierarchical summary receiver operating characteristic (HSROC) model and calculated the point estimates of specificity with sensitivity fixed at 0.90 using the HSROC curve. We identified 32 published and one unpublished studies, including 75 studies on five antibody test types: 18 of precipitin test (2810 participants), 46 of IgG (8197), three of IgA (283), six of IgM (733) and two of combined IgG and IgM (IgG + IgM) (920). The results of specificity with sensitivity fixed at 0.90 were as follows: precipitin test, 0.93 (95% credible intervals: 0.86, 1.00); IgG, 0.90 (0.86, 0.95); IgA, 0.74 (0.00, 1.00); IgM, 0.50 (0.37, 0.53); IgG + IgM, 0.47 (0.00, 1.00). However, the precipitin test showed imprecision and instability in the sensitivity analysis. Most studies had a high risk of bias due to the case-control design. Although there is lack of applicability for malignancy or immunosuppressive patients, our study suggests a preference for IgG over other antibody tests in CPA screening. Particularly, IgG should be used as an adjunct when ruling out CPA.

Longitudinal validity and prognostic significance of the St George's Respiratory Questionnaire in Mycobacterium avium complex pulmonary disease

T Ogawa, T Asakura, S Suzuki, S Okamori, T Kusumoto, Y Sato, ...

Respiratory Medicine 185, 106515 185 106515 - 106515 2021年06月

ISSN 0954-6111

BACKGROUND: Although previous cross-sectional studies showed the feasibility and clinical association of the St. George's Respiratory Questionnaire (SGRQ) in Mycobacterium avium complex pulmonary disease (MAC-PD), its longitudinal validity is poorly understood. We aimed to determine the longitudinal validity and prognostic significance of SGRQ. METHODS: In this prospective observational study conducted between May 2012 and August 2018, we evaluated 269 enrolled patients with MAC-PD and examined associations between baseline SGRQ total scores and mortality or clinical variables (anchors), including serum C-reactive protein levels and pulmonary function test results. RESULTS: Age- and sex-matched SGRQ scores indicated significantly greater impairment in patients with MAC-PD than in the general population (P < 0.001). On multivariable Cox proportional hazards regression analysis, the SGRQ total score ≥25 was an independent risk factor for mortality (adjusted hazard ratio, 5.90; 95% confidence interval, 1.65-37.7) as well as age, body mass index, and forced vital capacity (FVC). Mixed-effect model results showed a significant association between SGRQ symptom/total scores and forced expiratory volume in 1 s (FEV1), FVC, and diffusing carbon monoxide capacity. Older age, a positive smear, non-nodular/bronchiectatic form, and cavity regions were associated with SGRQ total score deterioration. Patients with a greater decline from baseline FEV1 (% predicted) exhibited significantly worse impairment in the SGRQ total score (mean ± SE, 4.69 ± 10.9 points, P = 0.001). CONCLUSIONS: SGRQ showed longitudinal validity in assessing disease severity and was sensitive to changes in patients with MAC-PD, especially changes in %FEV1. The SGRQ total score may be an important prognostic factor.
