Filter by:Program： Clinical Study of Relationship Between Granulocyte Activation, HDAC2 and Severe Asthma Aim：The early prediction of severe asthma, early intervention on the disease, reduce the family and the national finance. design:This study is a single center randomized controlled trial designed by the Department of respiratory medicine, Xijing Hospital, as the main research unit.Compare the case group(severe asthma group and mild-and-moderate asthma group) and control group(healthy control group) by detecting the activity of MPO、NE、MMP-9 and ECP in the peripheral blood and the activity of HDAC2 in PBMCs of patients. case:60 Case selection: Inclusion criteria: age 18-75 years old; diagnosis of asthma was clear; informed consent was signed. Exclusion criteria: poor compliance; cognitive ability is low; psychiatric disorders need to be combined with psychotropic medication.
The purpose of this study to determine the proportion and clinical characteristics of COPD patients with asthma symptoms (ACOS) and describe current practices in diagnosis and management in Viet Nam and Taiwan.
The purpose is to characterize the change of respiratory admittance induced by salbutamol inhalation in children and young adults. A variation threshold will be fixed to distinguish asthmatic and healthy subjects. This project could allow a better identification of asthmatic individuals needing a treatment, a reduction of morbidity of asthma, a reduction of unnecessary treatments administered in individuals with respiratory but not asthmatic symptoms, a better comprehension of bronchial hyperreactivity and its role in asthmatic disease.
The current study aims to explore the role of prebiotic supplementation in adults with and without Asthma/Exercise-Induced Bronchoconstriction (A/EIB). All participants will be asked to consume a prebiotic supplement, and a placebo, each for a total duration of four weeks, separated by a two-week wash out period. The investigators hypothesise that improvements in pulmonary function observed in adults with Asthma following prebiotic supplementation. We hypothesise that improvements in pulmonary function will be attributed, at least in part, to gut microbiota mediated improvements in human immune function.
Prospective, multicenter, single-arm (non-randomized) study of Targeted Lung Denervation (TLD) Therapy in subjects with severe asthma.
Severe asthma is a heterogeneous disease characterized by the need for treatment with high doses of inhaled corticosteroids. It affects 5%-10% of asthmatic patients, although it accounts for a significant percentage of the consumption of health care resources. Severe asthma comprises various clinical and pathophysiological phenotypes. In this current study, we aimed to clinical characteristics and cytokes profile in severe asthma patients.
It is recommended that patients with asthma owned a written action plan which must include the names, doses and dosing of the treatment they should take when acute respiratory symptoms occur. Current written action plans must be short to be readily used (1 page) and, therefore, cannot fit all acute situations. Moreover, they may not be available where and when required. The investigators sought that a digital action plan, available through Smartphone or tablet computer connected to the internet, could adequately provide suitable action plans according to the severity of the described exacerbation, and would be more easily available when useful. The aim of the study is to study the effect of the use of a digital action plan for asthma exacerbation, on the frequency of unscheduled medical contacts (phone calls, visits to physicians or to emergency departments, hospitalizations) in children and in adults with asthma. The investigators hypothesized that the use of the digital action plan could reduce avoidable unscheduled visits due to mild or moderate exacerbations that could successfully be managed by the patient or his/her caregivers.
The purpose of this study is to investigate the onset and maintenance of effect of benralizumab on lung function, blood eosinophils, asthma control metrics and quality of life during 12-week treatment in patients with uncontrolled, severe asthma with eosinophilic inflammation. A subset of patients will take part in body plethysmography substudy to further investigate the effect on lung function.
Behavioral problems are part of many of the chronic diseases that cause the majority of illness, disability and death. Tobacco, diet, physical inactivity, alcohol, drug abuse, failure to take treatment, sleep problems, anxiety, depression, and stress are major issues, especially when chronic medical problems such as heart disease, lung disease, diabetes, or kidney disease are also present. These behavioral problems can often be helped, but the current health care system doesn't do a good job of getting the right care to these patients. Behavioral health includes mental health care, substance abuse care, health behavior change, and attention to family and other psychological and social factors. Many people with behavioral health needs present to primary care and may be referred to mental health or substance abuse specialists, but this method is often unacceptable to patients. Two newer ways have been proposed for helping these patients. In co-location, a behavioral health clinician (such as a Psychologist or Social Worker) is located in or near the primary practice to increase the chance that the patient will make it to treatment. In Integrated Behavioral Health (IBH), a Behavioral Health Clinician is specially trained to work closely with the medical provider as a full member of the primary treatment team. The research question is: Does increased integration of evidence-supported behavioral health and primary care services, compared to simple co-location of providers, improve outcomes? The key decision affected by the research is at the practice level: whether and how to use behavioral health services. The investigators plan to do a randomized, parallel group clustered study of 3,000 subjects in 40 practices with co-located behavioral health services. Practices randomized to the active intervention will convert to IBH using a practice improvement method that has helped in other settings. The investigators will measure the health status of patients in each practice before and after they start using IBH. The investigators will compare the change in those outcomes to health status changes of patients in practices who have not yet started using IBH. The investigators plan to study adults who have both medical and behavioral problems, and get their care in Family Medicine clinics, General Internal Medicine practices, and Community Health Centers.
This study is aimed to evaluate the effectiveness of Asthma Control Test (ACT) guided treatment compared with usual care in asthma subjects in China. It is designed to assist Chinese subjects and physicians improving adherence to the guidelines through the inclusion of the ACT in the patient's asthma management plan. This is a prospective, multicentre, cluster-randomized, open-label 24-week study. In this cluster-randomization design, each study center, considered as a cluster, will be randomized to either ACT guided treatment group or control group (usual care group). For the subjects who are recruited in the ACT centers, they will be treated based on the ACT score. If ACT score are equal to (=) 25 for more than equal to (>=) 3 months then the treatment will stepped-down; if ACT score >=20, less than (<) 25 or ACT=25 for <3 months then there will be no change and if ACT score less than (<=) 19 then the treatment will stepped-up. For subjects who are recruited in the control centers, they will be treated based on doctor's subjective judgment. Assignment to a treatment will not occur, as no treatment intervention is provided for this study. A total of 528 asthma subjects are planned in the study. The randomization will be stratified according to the Tier of the hospitals (Tier 3 verses Tier 2).
