Active clinical trials for "Cough"

This is a randomised, double-blinded, placebo-controlled trial of BPZE1 that includes virulent B. pertussis challenge followed by a safety follow-up.

To find out the Comparison Of Coughing and Active Cycle of Breathing Technique to Improve Pulmonary Functions in Post-Surgical Patients

Diabetic patients with and without chronic cough will be included in this study. After giving their informed consent, the patients will perform a spirometry, chest X-ray at the inclusion visit. Cough will be assessed using the cough visual analog scale (VAS) and the Leicester Cough Questionnaire (LCQ). Within 60 days, the patient will perform neurophysiological tests. The neurophysiological assessment will be concluded with a skin biopsy to evaluate small fiber neuropathy. The aim of the study is to compare the proportion of small fiber neuropathy between diabetic patients with chronic cough and those without chronic cough.

In Interstitial Lung Disease (ILD) there is thickening of lung tissue, which makes it difficult for patients to breathe and get enough oxygen into their bodies. In addition to shortness of breath, daily cough is very common, with 4 out of 5 patients experiencing this symptom. Cough in particular has a major impact on the ability to exercise, be active, and to simply enjoy life. There are many reasons for cough in ILD, and very often there are multiple overlapping causes. It is hard to improve cough in these patients, with available medicines providing limited relief. One explanation for this gap is an incomplete understanding of cough in ILD. To improve patients' cough there is a need to better understand its cause. In other lung diseases, such as asthma, doctors and scientists have used phlegm tests to measure inflammation in the lung, which helps them choose the right medicine for the right patient. This has not been done for ILD, even though it has recently been found that many patients with ILD and everyday cough have abnormal phlegm tests. Using this strategy in ILD could improve patients' cough and quality of life, and possibly even slow progression of the disease.

Surgical resection is the primary treatment for pulmonary tumors. Surgeons has been frequently concerned about effectiveness, safety, and minimal invasive techniques. However, persistent cough, one of the most common complications of lung surgery, has received insufficient attention. This study set out to investigate the risk factors and treatment related to persistent cough after pulmonary resection.

Orally administered ME-015 (Suplatast Tosilate) has been available on the market as a prescription drug for allergy-related conditions in Japan since 1995 with a very good safety and tolerability profile. There is preclinical and exploratory clinical evidence suggesting that ME-015 may be effective in treating cough caused by idiopathic pulmonary fibrosis (IPF-cough). 80% of patients with idiopathic pulmonary fibrosis (IPF) are affected by a devastating dry cough that is often not responsive to standard cough treatments and causes significant psychological and physiological suffering as well as reduced quality of life. As of July 2023, there is no approved treatment for the indication of IPF-cough. There is an enormous unmet clinical need for an effective, safe and well-tolerated oral treatment. The COSMIC-IPF Phase 2 trial is the first clinical trial assessing ME-015 for the treatment of IPF-cough and aims to generate clinical proof-of-concept results regarding the safety and efficacy of ME-015 in this condition.

Dizocine (0.03 mg/kg) or saline followed by sufentanil 0.4ug/kg was administered, and induction was completed with 3 min of observation. Heart rate and mean arterial pressure (MAP) were recorded before induction of anesthesia, before and 1 min after intubation, and side effects during induction, such as vomiting, hypoxemia (SpO2 <90%), or other expected effects. The number of coughs was recorded in both groups, and the severity of cough was defined as follows: mild, 1-2 coughs; moderate, 3-4 coughs; severe, 5 or more coughs.

This is a laboratory-based study that will be performed at the Clinical Research Centre at the Royal Brompton Hospital,London. The objectives are: Determine whether adenosine triphosphate (ATP) is present or released in airways of idiopathic chronic cough patients Determine whether there is an increase in cough sensitivity and laryngeal sensitivity to exogenous ATP Examine the effects of exogenous ATP on the inflammatory response in the upper and lower airways. The participants will be: (i) Healthy subjects: non-smoker (8 subjects) and (ii) Chronic cough subjects attending Chronic Cough clinic (12 subjects). Each will be involved in: Study 1. Following recruitment, subjects will attend for a fiberoptic bronchoscopy. Study 2: Subjects will take part in a study of the effect of inhaling nebulized ATP. Subjects will be studied on 2 days separated by at least 5 days. On each day, after measurements of lung function, FeNO and cough questionnaires, the subject will inhale either saline or ATP solution from a nebulizer, following which laryngeal hypersensitivity, capsaicin cough challenge and sputum induction will be performed. Results will be expressed as mean ± standard error of the mean (SEM). Study data will be analysed by the Investigators at the completion of the study. Planned analyses will be done by comparing chronic cough patients to the healthy controls. The Spearman rank-correlation test will be used to determine correlations.

The hypothesis of this study is that Magnesium sulfate pretreatment (50mg/kg) will reduce the incidence of cough and chest wall rigidity caused by remifentanil administration. The purpose of this study was to investigate the effect of magnesium sulfate administered before induction of anesthesia on thoracic stiffness and cough response caused by opioid analgesics administered for general anesthesia.

Cough is a common symptom that leads patients worldwide to seek medical attention. Subacute cough refers to a cough of 3-8-week duration, and is typically refractory to standard anti-tussive therapy, and a tendency to spontaneous healing was common. Few clinical trials have evaluated therapeutic options for subacute cough. Airway inflammation is an important feature of most of subacute cough, Cysteinyl leukotrienes and FeNO correlates with airway inflammation. Subacute cough often represents a prolonged post-viral response. Cysteinyl leukotrienes increase in virus infection. Airway inflammation induce epithelial cells produce iNOS(inducible nitric oxide synthase,iNOS), and FeNO increase in theory. Montelukast is a cysteinyl leukotriene type 1 receptor antagonist that is reported to improve cough16 and reduces FENO and prevents increases in FENO during reduction of inhaled corticosteroid dose, But A meta-analysis of the effectiveness of LTRA( leukotriene receptor antagonist,LTRA)in treating children with prolonged non-specific cough concluded that, with the lack of evidence, the routine use of LTRA in treating children with non-specific cough cannot be recommended. A randomised, placebo-controlled trial showed montelukast is not an effective treatment for postinfectious cough. Non-specialists or general practitioners of Japan prescribe LTRA very often, which increase. The aim is to research whether FeNO can be used as a biomarker to direct montelukast treatment and optimize treatment regimen of sub-acute cough.
