Abstract:

Introduction: Cough is the commonest reason for which medical advice is sought. In assessment of chronic cough and in developing anti-tussive medications, inhalational cough challenges with capsaicin and citric acid are commonly employed. However the ability of these inhalational cough challenges to distinguish health and disease is not clear and it is not known which end point is best in making such assessments. Methods: Subjects belonging to five different categories (healthy volunteers, subjects with COPD, asthma, healthy current smokers and chronic cough) were compared with each another by

Includes bibliographical references.<br>Background: There are between 20 - 40 million cases of whooping cough annually world-wide, 90% of which occur in developing countries, resulting in an estimated 200 - 300 O00 fatalities each year. Much of the morbidity is due to the paroxysmal cough. Corticosteroids, salbutamol (a β₂- adrenergic stimulant), and pertussis-speciﬁc immunoglobulin have been proposed as standard treatment for the cough. Antihistamines have also been administered. No systematic review of the effectiveness of any of these interventions or others has been performed. Objective: i

Abstract:

Cough is a common symptom of both acute and chronic respiratory illness. It is poorly understood and treatment options are sparse. One reason is that there are few validated objective measures of cough frequency and severity. In this thesis I have further validated the Leicester Cough Monitor, an automated cough detection system capable of detecting coughs over 24 hours. I have demonstrated that automated cough numbers were similar to those derived from the gold standard of manual counting in healthy adults and in patients with respiratory disease. Cough frequency was then measured using the L

Abstract:

Introduction: Varying methods of cough quantification have been used to describe cough frequency, although there is no consensus which method best relates to subjective rating of cough. With increased availability of semi-automated cough recording devices, the capability to carryout anti-tussive studies is greatly increased. However, there is no data available describing the magnitude of change in cough frequency necessary to provide therapeutic benefit. Female patients are over represented in specialist cough clinics. There is little data describing pulmonary function and airway inflammation

Rationale Cough is an important symptom in asthma. In addition, cough is both troublesome to patients and may be important in the development of more severe disease.

Until now, subjective measures of cough have been used in mechanistic and therapeutic studies relating to both cough in asthma and chronic cough.

Abstract:

Although the aetiology of chronic cough in guidelines is clearly stated as asthma and related syndromes, gastro-oesophageal reflux disease, and upper airways disease, the inflammatory mechanisms underlying these conditions differ. Recent studies on asthma have increasingly focused on its molecular phenotypes instead of clinical characteristics. Predominantly in this thesis I hypothesize that by dividing cough patients into the clinical characteristics of eosinophilic and neutrophilic groups will enhance our ability to recognise the type of airway inflammation, and consequently will lead us to

It was hypothesised that IPF patients have increased airway expression of the capsaicin receptor TRPVF1 and a coFexpressed receptor TRPAF1.

Motor Neurone Disease (MND) is a disabling and inevitably fatal disease, usually with a life expectancy of 2-3 years from symptom onset. It is characterised by progressive wasting and weakness in bulbar, limb and respiratory muscles. There is no cure and treatment is mainly symptomatic. Neuromuscular respiratory failure, with or without a chest infection, is the commonest cause of death in MND patients. It has been shown that supporting respiratory function with non-invasive ventilation, improves survival and quality of life despite progression of the disease. The patients with respiratory mus
