Characteristics of Adult Severe Refractory Asthma in Korea Analyzed From the Severe Asthma Registry

Severe refractory asthma: an update.

Asthma is a heterogeneous disease in which adequate asthma control cannot be achieved in a substantial proportion despite currently available treatment possibilities. This subgroup has been defined as "severe refractory" asthma. Over the past years considerable progress has been made regarding a more exact definition of severe refractory asthma. A systematic approach to evaluate the asthma pati...

Optimal Management of Severe/Refractory Asthma

Asthma is a chronic inflammatory disease of the airways, affecting approximately 300 million people worldwide. Asthma results in airway hyperresponsiveness, leading to paroxysmal symptoms of wheeze, cough, shortness of breath, and chest tightness. When these symptoms remain uncontrolled, despite treatment with high doses of inhaled and ingested corticosteroids, asthmatic patients are predispose...

Glucocorticoid receptor-binding characteristics in severe asthma.

The cellular mechanisms associated with severe asthma are still poorly understood. This study investigated the association between glucocorticoid-receptor (GR) alterations and continuous oral glucocorticoid therapy requirement in severe asthma. GR-binding affinity (Kd) and receptor number (n) in peripheral blood monocytes (PBM) obtained from 10 normal subjects, 10 untreated, intermittent asthma...

Evaluation of Omeprazole in the Treatment of Moderate to Severe Persistent Asthma in Children

Background and Objective: Asthma is the most common chronic disease of childhood. The disease is caused by a temporary blockage of airflow due to chronic inflammation of the airways . One of the conditions that often occur with asthma and exacerbate disease, is gastroesophageal reflux. The aim of this study is to evaluate the role of acid suppressing therapy in patients with refractory asthma...
