Active clinical trials for "Asthma"

The aim of the study is to assess the effect of specific immunotherapy (SIT) to dust mites on clinical symptoms, reliever drugs usage, inhaled glucocorticosteroid usage, quality of life, lung function, chosen markers of inflammation, induction of regulatory lymphocytes, bronchial hyperreactivity with methacholine, and presence and type of allergy after two years of SIT in children with asthma.

Bronchial Asthma is a common childhood chronic disease characterized by chronic inflammation of the airways. Frequent relapse of asthma has serious impacts on the child's growth, impairs quality of life (QoL) and mortality, posing a huge economic burden on both family and society. According to Traditional Chinese Medicine (TCM) principles and theory, the main reason for children suffering from asthma are congenital deficiencies at birth which were not corrected and/or lack of appropriate care in the early childhood, leading to insufficiency of the lung, spleen and kidney, resulting in susceptibility to external pathogenic factors. During the interval phase of the illness, wheezing is not prominent and the "Lung-Spleen Qi Deficiency" (LSQD) syndrome is most commonly seen. TCM treatment aims to strengthen the body's immune system by nourishing the spleen, replenishing "Qi"(vital energy), tonifying the lungs and strengthening the exterior, thereby reducing incidences of relapse and improve QoL. It is hypothesized that TCM has adjuvant roles in the management of mild-moderate childhood asthma. Hence the primary aim of this study is to investigate the efficacy of using herbal TCM as adjuvant therapy in the management of symptoms and QoL in asthmatic patients. A randomized, double-blind cross-sectional, 2-arms placebo-controlled study will be carried out. Pediatric patients with mild-moderate asthma identified with LSQD will be randomized to either control or treatment group. Study participants in control group will continue their conventional western medicine (CWM) while those in TCM group will consume a decoction of herbal TCM for 12-weeks in addition to their CWM. Pulmonary function tests, Asthma Control Test, QoL and TCM questionnaires will be used as outcome measurement tools. In addition, liver and kidneys functions will be monitored for signs of toxicity.

The purpose of this study is to research the differences of small airways function between subjects with diagnosis of chronic obstructive pulmonary disease(COPD) and asthma-COPD overlap(ACO).The assessment of quality of life is also carried out through questionnaires.

This study is a 24-week, randomized, parallel group comparative effectiveness study to evaluate the risk of stepping down therapy for patients with well-controlled asthma treated with combination Inhaled corticosteroids (ICS) and Leukotriene receptor antagonist（LTRA).

This study aims to investigate the efficacy and safety of Bronchial Thermoplasty on moderate bronchial asthma in China, by observing the improvement of quality of life, the decrease of acute attack and emergence, as well as the incidence of related complications.

This study is a multi-center randomized controlled trial of children with asthma. The objective of the study is to assess the efficacy of China Children Asthma Action Plan (CCAAP), which is the first asthma action plan for children with asthma in China, in asthma management.

Airway irritation, cough and bronchial spasm are common symptoms in patients with airway inflammatory diseases such as asthma. The primary focus of this exploratory study is to determine if there is an increase in tissue temperature in airway mucosa during asthma exacerbation. The results of this study will bring a better understanding of the potential involvement of an increase in airway mucosa temperature in the pathogenesis of various symptoms in these patients. The finding should help to advance the development of new therapeutic strategies for these debilitating diseases.

Many studies have investigated the efficacy and safety of Intravenous magnesium sulfate and inhaled steroids in addition to the standard treatment for patients with severe asthma attacks. In this 2x2 factorial design blinded randomized study, no interaction of hypothesized treatments is expected.Investigators hypothesize that two doses of intravenous magnesium sulfate,a high dose followed by a (lower) standard dose, will shorten the time to medical readiness for discharge compared to a single standard dose followed by placebo.The second hypothesis is that nebulized inhaled budesonide will be superior to placebo.

The purpose of this study is to determine the effectiveness of telemedicine multifaceted intervention in symptoms patients with asthma.

The purpose of this study is to evaluate the clinical efficacy of traditional Chinese medicine in the treatment of asthma, and to promote the application in community hospitals.
