[CQ IN THE LONG-TERM MANAGEMENT OF ADULT ASTHMATIC PATIENTS WHO ARE NOT ADEQUATELY CONTROLLED WITH INHALED CORTICOSTEROIDS MONOTHERAPY, WHICH IS MORE BENEFICIAL: ADDING A LONG ACTING BETA2 AGONIST OR A LONG ACTING MUSCARINIC ANTAGONIST?].

Long-acting beta2-agonists (LABA) are preferred add-on treatment for adult asthmatic patients whose symptoms cannot be controlled with inhaled corticosteroids (ICS) alone. However, over the last decade, long-acting muscarinic antagonists (LAMA) have gained approval for use in treating asthma, and their efficacy is anticipated. Therefore, we conducted a systematic review to investigate whether the addition of LABA or LAMA is more beneficial for the long-term management of adult asthmatic patients poorly controlled on ICS monotherapy.

Disseminated Infection Mimicking Sarcoidosis: A Case Report and Review of Literature on Japanese Patients.

Sarcoidosis is a systemic inflammatory disease characterized by noncaseating epithelioid cell granulomas. However, certain infections can exhibit similar histological findings. We present a case of a 69-year-old man who was initially diagnosed with sarcoidosis and later was confirmed, through 16S rRNA sequencing, to have disseminated infection.

Serum IgA augments adhesiveness of cultured lung microvascular endothelial cells and suppresses angiogenesis.

Immunoglobulin A (IgA) is important in local immunity and is also abundant in the blood. This study aimed to evaluate the effects of serum IgA on cultured lung microvascular endothelial cells (HMVEC-Ls), which are involved in the pathogenesis of inflammatory lung diseases. Serum IgA induced adhesion molecules and inflammatory cytokine production from HMVEC-Ls, and enhanced adhesion of peripheral blood mononuclear cells to HMVEC-Ls.

Background: This study evaluated the efficacy and safety of the combination chemotherapy of docetaxel plus S-1 in patients with previously treated non-small cell lung cancer (NSCLC) compared to docetaxel alone.

Methods: Patients with previously treated NSCLC were randomly assigned to docetaxel alone (arm A) or a combination of docetaxel and S-1 (arm B) for a maximum of four cycles. The primary endpoint was overall survival (OS).

Associations of Polymorphisms with Chronic Kidney Disease in Japanese Rheumatoid Arthritis Patients.

Objectives: The prevalence of chronic kidney disease (CKD) was reported to be higher in rheumatoid arthritis (RA) patients than in normal healthy individuals. Human leukocyte antigen () was associated with RA or CKD. Few studies on the association of with CKD in RA have been reported.

Concordance between transbronchial lung cryobiopsy and surgical lung biopsy for interstitial lung disease in the same patients.

Background: The diagnostic accuracy and safety of transbronchial lung cryobiopsy (TBLC) via a flexible bronchoscope under sedation compared with that of surgical lung biopsy (SLB) in the same patients is unknown.

Methods: Retrospectively the data of fifty-two patients with interstitial lung diseases (median age: 63.5 years; 21 auto-antibody positive) who underwent TBLC followed by SLB (median time from TBLC to SLB: 57 days) was collected.

Allergic bronchopulmonary aspergillosis with atopic, nonatopic, and sans asthma-Factor analysis.

Background: Allergic bronchopulmonary aspergillosis (ABPA) develops in the presence or absence of asthma, either atopic or nonatopic. We have tried to explore the essential components in the pathogenesis of the disease, which are either consistent and variable according to the presence and type of asthma.

Methods: Non-cystic fibrosis ABPA cases satisfying Asano's criteria were extracted from a prospective registry of ABPA and related diseases in Japan between 2013 and 2023.

A 65-Year-Old Man With Massive Hemoptysis.

A 65-year-old man experienced a cough and mild hemoptysis suddenly one morning. He was prescribed tranexamic acid and carbazochrome salicylate by the local clinic at the first visit, and his hemoptysis stopped. However, 2 days later, he experienced recurrent hemoptysis that was prolonged intermittently.

Phenotype characterization and biomarker evaluation in moderate to severe type 2-high asthma.

Background: There are two major pathological phenotypes of asthma, type 2 (T2)-high and T2-low asthma, which are important in determining treatment strategies. However, the characteristics and phenotypes of T2-high asthma have not yet been fully identified.

Objective: This study aimed to identify the clinical characteristics and phenotypes of patients with T2-high asthma.

Chronic Pulmonary Aspergillosis Caused by Aspergillus tubingensis Diagnosed by a Bronchoscopic Biopsy.

We herein report a case of chronic pulmonary aspergillosis (CPA) caused by Aspergillus tubingensis diagnosed by a bronchoscopic biopsy with negative serological and sputum culture findings. A 66-year-old man was referred for the assessment of a pulmonary cavity. Computed tomography showed a thick-walled cavity in the upper right pulmonary lobe.

Low Serum IL-18 Levels May Predict the Effectiveness of Dupilumab in Severe Asthma.

Objective Dupilumab, a monoclonal antibody specific for the human interleukin (IL)-4 receptor α, is used to treat severe asthma, especially in patients with elevated blood eosinophil counts and fractional exhaled nitric oxide (FeNO). The therapeutic response to dupilumab is highly variable. In this study, we explored new serum biomarkers to accurately predict the effect of dupilumab and examine the effect of dupilumab based on changes in the clinical parameters and cytokine levels.

Diagnostic Utility of a Mycobacterium Multiplex PCR Detection Panel for Tuberculosis and Nontuberculous Mycobacterial Infections.

The prevalence of nontuberculous mycobacterial diseases is increasing worldwide, and tuberculosis remains highly prevalent. Rapid and accurate microbial diagnoses of both tuberculosis and nontuberculous mycobacterial infections are required. A novel PCR-reverse sequence-specific oligonucleotide probe (PCR-rSSO) method-based mycobacterial detection panel (Myco-Panel) test was developed for the rapid identification of 30 mycobacterial species and subspecies.

Clinical benefit of platinum doublet combination therapy in older adults with advanced non-small cell lung cancer: A prospective multicenter study by the National Hospital Organization in Japan.

Background: Previous trials suggest that older adults with non-small cell lung cancer (NSCLC) derive benefit from platinum doublet combination therapy, but its superiority is controversial. Although geriatric assessment variables are used to assess the individual risk of severe toxicity and clinical outcomes in older patients, the standard first-line treatment is still debated. Therefore, we aimed to identify the risk factors for clinical outcomes in older patients with NSCLC.

Associations of Polymorphisms with Anti-SARS-CoV-2 Spike and Neutralizing Antibody Titers in Japanese Rheumatoid Arthritis Patients Vaccinated with BNT162b2.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes Coronavirus Disease 2019. Anti-SARS-CoV-2 spike (S) and neutralizing antibodies (Abs) are measured to evaluate the efficacy of vaccines. Human leukocyte antigen () may be associated with vaccine efficacy.

Antibodies against Serum Anti-Melanoma Differentiation-Associated Gene 5 in Rheumatoid Arthritis Patients with Chronic Lung Diseases.

Chronic lung diseases (CLD), including interstitial lung disease (ILD) and airway diseases (ADs), are common complications of rheumatoid arthritis (RA). Rheumatoid factor (RF) and anti-citrullinated peptide antibodies are reported to be associated with CLD in RA patients. The presence of anti-melanoma differentiation-associated gene 5 (MDA5) antibodies (Abs) is associated with clinically amyopathic dermatomyositis developing into rapidly progressive ILD.

Association of a variant with interstitial lung disease in Japanese rheumatoid arthritis.

Background: Interstitial lung disease (ILD) occasionally occurs in rheumatoid arthritis (RA) and confers a dismal prognosis. We previously reported that a single-nucleotide variant (SNV) of was associated with ILD in RA. However, the pathogenesis of ILD in Japanese patients with RA could not be explained solely by this SNV because its frequency is extremely low in the Japanese population.

Characterization and cluster analyses of elderly asthma in comparison with nonelderly patients with asthma in Japan.

Background: Asthma is a heterogeneous disease with multiple phenotypes that are useful in precision medicine. As the population ages, the elderly asthma (EA, aged ≥ 65 years) population is growing, and EA is now a major health problem worldwide.

Objective: To characterize EA and identify its phenotypes.

Idiopathic Pulmonary Fibrosis Is Associated with Common Genetic Variants and Limited Rare Variants.

Idiopathic pulmonary fibrosis (IPF) is a rare, irreversible, and progressive disease of the lungs. Common genetic variants, in addition to nongenetic factors, have been consistently associated with IPF. Rare variants identified by candidate gene, family-based, and exome studies have also been reported to associate with IPF.

A phase II study of S-1 and cisplatin with concurrent thoracic radiotherapy followed by durvalumab for unresectable, locally advanced non-small-cell lung cancer in Japan (SAMURAI study): primary analysis.

Background: The standard of care for unresectable, locally advanced non-small-cell lung cancer (LA-NSCLC) is chemoradiotherapy (CRT) followed by durvalumab, based on the PACIFIC study. Although multiple Japanese phase II studies have shown high efficacy and tolerability of CRT with cisplatin plus S-1 (SP), no prospective study using durvalumab after SP-based CRT has been reported.

Objectives: We conducted a multicenter phase II study of this approach, the interim analysis of which showed a high transition rate to durvalumab consolidation therapy.

Biologics for severe asthma: The real-world evidence, effectiveness of switching, and prediction factors for the efficacy.

Biologics have been a key component of severe asthma treatment, and there are currently biologics available that target IgE, IL-5, IL-4/IL-13, and TSLP. Randomized controlled trials have established clinical evidence, but a significant portion of patients with severe asthma in real-life settings would have been excluded from those trials. Therefore, real-world research is necessary, and there is a growing body of information about the long-term efficacy and safety of biologics.

Validity of Platelia Aspergillus IgG and Aspergillus Precipitin Test To Distinguish Pulmonary Aspergillosis from Colonization.

When Aspergillus, an ubiquitous, saprophytic fungus, is detected in respiratory tract specimens collected from chronic respiratory disease patients, it is important to determine whether it is a true infection or colonization. We investigated the usefulness of the Bio-Rad Platelia Aspergillus IgG (Platelia Aspergillus IgG) enzyme-linked immunosorbent assay (ELISA) method and the Aspergillus precipitin test to distinguish pulmonary aspergillosis from colonization. Between January 2017 and November 2021, 51 confirmed, untreated pulmonary aspergillosis (33 chronic pulmonary aspergillosis [CPA] and 18 allergic bronchopulmonary aspergillosis [ABPA]) and 77 colonization patients were included in this study.
