Real-world efficacy of anti-IL-5 treatment in patients with allergic bronchopulmonary aspergillosis.

Despite standard treatment with systemic corticosteroids and/or antifungal triazoles, a substantial proportion of patients with allergic bronchopulmonary aspergillosis (ABPA) experience frequent relapses and require long-term treatment despite unfavorable adverse effects. We investigated the efficacy and safety of anti-interleukin (IL)-5/IL-5 receptor α chain (Rα) monoclonal antibodies (mAbs) in patients with ABPA complicated by asthma. ABPA cases treated with anti-IL-5/IL-5Rα mAbs were collected from 132 medical institutes in 2018 and published case reports in Japan.

Pulmonary emphysema is associated with fungal sensitization in asthma.

Background: Fungal sensitization is a risk factor for severe asthma. Colonization in the lower respiratory tract is one of the forms of fungal exposure, and it is related to fungal sensitization. Pulmonary emphysema was recently reported to be an underlying disease of fungal colonization.

Persistent Asthma from Childhood to Adulthood Presents a Distinct Phenotype of Adult Asthma.

Background: In approximately 30% of children with asthma, the condition persists into adulthood. The longer duration of asthma in these patients is a risk factor for poor asthma control. However, the characteristics of adult patients with asthma that has persisted since childhood are not well documented.

Histological types and localizations of lung cancers in patients with combined pulmonary fibrosis and emphysema.

Background: Most patients with combined pulmonary fibrosis and emphysema (CPFE) are males, and heavy smokers. CPFE is more prevalent than fibrosis in patients with lung cancer, and patients with CPFE usually have a poor prognosis. This study reviewed the differences in the prevalence of lung cancer among patients with normal, fibrosis, emphysema and CPFE via chest computed tomography (CT), and the relationship between histopathology and the localizations of lung cancer.

The utility of galactomannan antigen in the bronchial washing and serum for diagnosing pulmonary aspergillosis.

Background: The diagnosis of pulmonary aspergillosis is difficult because the sensitivity of the conventional methods for the detection of Aspergillus such as culture and cytology, is poor. To improve the sensitivity for Aspergillus detection, the detection of galactomannan antigen has been investigated. The serum galactomannan (GM) antigen has been recognized to be a useful tool for the diagnosis of invasive pulmonary aspergillosis.

Clinical relevance of plasma miR-106b levels in patients with chronic obstructive pulmonary disease.

Chronic obstructive pulmonary disease (COPD) is characterized by both chronic inflammation in the airway and systemic inflammation; however, the molecular mechanism of COPD has not been fully elucidated. By measuring microRNA (miRNA) expression in the plasma of COPD subjects, we aimed to identify the clinical relevance of plasma miRNA levels in these patients. Blood samples were obtained from COPD patients and age-matched normal controls.

The relationship between the clinical course and cytokine in a patient with cigarette smoking-induced acute eosinophilic pneumonia - A case report.

A 19-year-old female was admitted to our hospital because of a sudden onset fever and cough, and she was diagnosed to have acute eosinophilic pneumonia (AEP). The cause was thought to be cigarette smoking, because she had started smoking just before the development of AEP and her condition improved after cigarette smoking cessation, without corticosteroid treatment. The cytokines which are thought to be involved in eosinophilic accumulation in the lungs were analyzed using bronchoalveolar lavage fluid (BALF) and serum.

Effects of inhaled tiotropium plus transdermal tulobuterol versus tiotropium alone on impulse oscillation system (IOS)-assessed measures of peripheral airway resistance and reactance, lung function and quality of life in patients with COPD: a randomized crossover study.

Background: The addition of transdermal tulobuterol (Tulo) to inhaled tiotropium bromide (Tio) produced beneficial effects on spirometry-assessed parameters of respiratory function, disease-related symptoms and quality of life in patients with chronic obstructive pulmonary disease (COPD).

Aim: To compare the effects of Tio plus Tulo versus Tio alone on peripheral airway obstruction and quality of life in Japanese patients with COPD using impulse oscillation system (IOS)-assessed measures.

Patients And Methods: Patients aged 50-80 years with clinically stable COPD and a forced expiratory volume in 1 s (FEV(1)) that was 30-80% of the predicted value were randomized to receive Tio 18 μg once daily, or combination therapy with Tio 18 μg once daily plus Tulo 2 mg once daily for 4 weeks.
