Filter by:Chronic cough is a common troublesome symptom which has a global prevalence of approximately 10%, but with wide variations across continents. The aim of this study is to evaluate the effectiveness of treatment, patient-reported outcomes and burden of disease in patients with chronic cough referred to a specialist clinic. The proposed study will use pre-defined diagnostic criteria, investigations and treatment algorithms such that all recruited patients will undergo the same investigations and follow a set management algorithm. This study will objectively and subjectively assess coughing at baseline and after treatment in a real-world clinical setting. This will allow us to understand the relationship between any objective reduction in cough after treatment, and whether this translates to any significant improvement in subjective questionnaire scores. We will assess the impact of health conditions on lost productivity in monetary units and assess the amount of absenteeism, presenteeism and daily activity impairment attributable to unexplained chronic cough/refractory chronic cough. Finally, a patient survey at the end of the study will evaluate the patients' satisfaction and experience of investigation, management trials and use of questionnaires.
Randomized controlled study to investigate the role of intraoperative vagal nerve block for preventing the postoperative cough in patients who received the pulmonary resection for lung cancer
The purpose of this study is to evaluate if office-based injection of a local anesthetic/steroid combination at the area of one superior laryngeal nerve can decrease cough frequency and alleviate symptoms of chronic cough in patients with neurogenic cough.
Prospective randomized placebo-controlled trial assessing the efficacy of superior laryngeal nerve block for adults with neurogenic cough refractory to proton pump inhibitor as determined by improvement in validated cough severity questionnaires before and after injection of Marcaine and Kenalog compared to placebo (saline injection).
This protocol is designed with the aim of exploring the efficacy of Susu on shortening duration and reducing severity of cough, and observe the safety used in children.
The purpose of this study is to assess whether a 5-day treatment with orally administered prednisone provides patient-relevant benefits by improving the cough-related QoL of patients with post-infectious cough triggered by an Upper Respiratory Tract Infection (URTI) and seeking care in adult primary care practices. The study aims to describe an efficacy and safety profile for a 5-day prednisone treatment compared to a 5-day course of placebo.
To explore the related factors of cough after Uniport video-assisted thoracoscopic surgery pneumonectomy, and to provide theoretical basis and social accumulation of new knowledge for the diagnosis and treatment of cough after pneumonectomy in the future.
Cough variant asthma (CVA), subtype of bronchial asthma, is considered to be one of the most common causes of chronic cough in different cough guidelines of United States, Europe, China and other countries. From a multicenter survey in China, over one third of chronic cough is caused by CVA, which is higher than western countries. CVA differs from classic asthma, usually manifesting a symptom of only coughing without wheezing or dyspnea and particularly coughing at night. With less clinical manifestation and medical intervention, CVA patients are easily be neglected and misdiagnosed, and 30-40% of them will develop to typical asthma in the next few years. Currently there's no specific therapy recommendation for CVA in GINA. Although cough guidelines in China recommend that CVA patients should be treated as typical asthma, no recommendation on details about ICS/LABA dosage and duration. There are only a few sporadic CVA therapy researches with small sample size. Two studiesfound that CVA patients can't get cough symptom relief even after treating by low dose of ICS/LABA for 3 months. Some patients' cough symptom relapses during the 24-week follow-up phase after treating by ICS/LABA for 3 months. Overall, the best treatment of CVA is not yet clear. GINA 2018 emphasize that asthma need long-term management. Euro-SMART study found that budesonide/formoterol 2 inhalation twice daily plus as needed can reduce daytime asthma symptoms and night-time awakenings, as well as reduce exacerbation risk more than 1 inhalation twice daily. Based on the above reasons, We assume that increase the dosage of ICS/LABA can decrease relapse rate in CVA patients with severe cough. This multi-center, randomized, controlled clinical trial can help to clarify the best dosage of budesonide/formoterol of CVA in China.
our study aimed to evaluate the effect of nebulized lidocaine to decrease the incidence of cough and sore throat after extubation after surgeries requiring endotracheal intubation.
Objective to study the pharmacokinetic, safety and efficacy of Single-dose and multiple-dose of benzonatate in Chinese healthy male and female subjects.
