Clinical features in patients with COVID-19 treated with biologics for severe asthma.

Background: Few studies have reported the clinical features of patients with coronavirus disease 2019 (COVID-19) who were treated with biologics for severe asthma (SA).

Objective: We sought to elucidate the clinical features and mutual interaction between COVID-19 and SA in terms of disease severity during the Omicron epidemic.

Methods: A retrospective study among patients with SA who received any biologic therapy from January 2022 to February 2023 at Jikei University Hospital (Tokyo, Japan) was performed.

Long-Term Efficacy and Clinical Remission After Benralizumab Treatment in Patients with Severe Eosinophilic Asthma: A Retrospective Study.

Background: Few studies on the long-term efficacy of benralizumab, an anti-interleukin-5 receptor α monoclonal antibody, have been conducted for patients with severe eosinophilic asthma (SEA), especially regarding the improvement of pulmonary function and clinical remission in a real-world setting.

Objective: To elucidate the long-term efficacy and clinical remission rate (CRR) in patients with SEA.

Methods: From July 2018 to July 2022, 23 Japanese patients with SEA received benralizumab for two years or more at Jikei University Hospital.

Real-World Effectiveness of Dupilumab for Patients with Severe Asthma: A Retrospective Study.

Background: Treatment with dupilumab, an anti-interleukin (IL)-4 receptor α monoclonal antibody that blocks both the IL-4 and IL-13 pathways, has demonstrated efficacy for the treatment of severe asthma (SA) with type 2 inflammation. However, few studies have focused on the efficacy of this biologic for the treatment of SA in a real-world setting.

Methods: From April 2019 to December 2021, 26 Japanese patients with SA received dupilumab at Jikei University Hospital.

Impaired TRIM16-Mediated Lysophagy in Chronic Obstructive Pulmonary Disease Pathogenesis.

Insufficient autophagic degradation has been implicated in accelerated cellular senescence during chronic obstructive pulmonary disease (COPD) pathogenesis. Aging-linked and cigarette smoke (CS)-induced functional deterioration of lysosomes may be associated with impaired autophagy. Lysosomal membrane permeabilization (LMP) is indicative of damaged lysosomes.

Effectiveness of Switching Biologics for Severe Asthma Patients in Japan: A Single-Center Retrospective Study.

Background: In Japan, biologic therapy was initiated for patients with severe asthma in 2009. In recent years, four biologics with different mechanisms of action have become available in the clinical setting. However, the efficacy of switching between biologics remains uncertain.

Effect of anti-interleukin-17 biologics on Krebs von den Lungen-6 level in patients with psoriasis.

Interleukin (IL)-17 plays critical roles in the pathogenesis of both psoriasis and interstitial pneumonia (IP). We hypothesized that anti-IL-17 biologics might suppress both clinically relevant and latent IP activity and decrease Krebs von den Lungen-6 (KL-6) level in psoriasis patients. We aimed to elucidate the effects of anti-IL-17 biologics on KL-6 levels.

Characteristics of anti-IL-17/23 biologics-induced interstitial pneumonia in patients with psoriasis.

Objectives: Anti-IL-17/23 biologics are increasingly used to treat psoriasis. We aimed to elucidate characteristics of drug-induced interstitial pneumonia (DIIP) caused by anti-IL-17/23 biologics.

Methods: We retrospectively analyzed the clinical data of psoriasis patients treated with anti-IL-17/23 biologics.

Efficacy of benralizumab for patients with severe eosinophilic asthma: a retrospective, real-life study.

Background: Benralizumab, an anti-interleukin-5 (IL-5) receptor α monoclonal antibody, significantly reduces the number of annual exacerbations and oral corticosteroid (OCS) maintenance doses for patients with severe eosinophilic asthma (SEA). However, few studies on the efficacy of this biologic in real life are available. The aim was to elucidate the efficacy of benralizumab by evaluating changes in clinical parameters after benralizumab treatment in patients with SEA.

Dasatinib-induced Nonspecific Interstitial Pneumonia That Developed 7 Years after the Initiation of Dasatinib.

We report the case of a 56-year-old man with chronic myeloid leukemia (CML) who developed dasatinib-induced interstitial lung disease (ILD) 7 years after starting dasatinib, a BCR-ABL1 inhibitor. The patient presented with dyspnea. Chest imaging showed diffuse ground-glass opacities.

A case of invasive pulmonary aspergillosis diagnosed by transbronchial lung biopsy during treatment for diabetic ketoacidosis in a type 1 diabetic patient.

Invasive pulmonary aspergillosis (IPA) patients with non-hematological malignancy are far less than with hematological malignancy patients. We encountered a very rare case of IPA in which type 1 diabetes was the only conceivable risk factor. Further, according to the diagnostic categories of the European Organization for Research and Treatment of Cancer/Invasive Fungal Infections Cooperative Group and the National Institute of Allergy and Infectious Diseases Mycoses Study Group (EORTC/MSG) criteria for IPA, the frequency of proven diagnosis is very low.

Pulmonary alveolar proteinosis developing during steroid treatment in a patient with organizing pneumonia in association with atypical chronic myeloid leukemia.

Organizing pneumonia (OP) and pulmonary alveolar proteinosis (PAP) are rare complications in patients with hematologic disorders. We herein report a case of PAP that developed during steroid treatment for OP in a patient with atypical chronic myeloid leukemia. Physicians should pay close attention to these complications in patients with hematologic malignancies.
