Reflux is an important factor in many different lung diseases and its manifestations are under recognised. The pathological basis of reflux has recently undergone major changes and clinicians' understanding has improved with diagnostic technology. This book aims to educate and inform professionals of these latest developments and give practical advice to their application in the clinical setting. It contains contributions written by world experts discussing their latest research, ideas and future directions in this fast moving area. Pharmacological, surgical and behavioural techniques in the prevention and treatment of reflux are discussed in each chapter. Special circumstances, such as eosinophilic inflammation in relation to asthma, cough and eosinophilic bronchitis are also highlighted. This book brings together the various different strands of research in reflux in relation to airways disease, to provide readers with a board summary of how the different but overlapping areas impacted by reflux affect the respiratory tract.
Professor Alyn Morice was trained at Cambridge University with the clinical attachment at St George's Hospital, London. Having obtained his MRCP, he undertook research in asthma at St Mary's Hospital, London studying the clinical pharmacology of airway nerves. During this time, a patient presented with an unexplained cough which was the first observation of ACE inhibitor cough and subsequently led to the demonstration of the Cough Hypersensitivity Syndrome in a Lancet paper of 1987. Professor Morice was then appointed Lecturer in Clinical Pharmacology at Cambridge University and started a lifelong interest in cough challenge and its role in dissecting the physiology of airway nerves. Appointed as Senior Lecturer and then Reader at the University of Sheffield, Professor Morice continued to study both the in vitro and in vivo pharmacology of the airway and pulmonary nerves. He founded the first dedicated Cough Clinic in the United Kingdom, which continues to see over 400 new patients per annum and has a national referral pattern.
Professor Morice moved to Hull in 1998 to take up the Foundation Chair in Respiratory Medicine. The aetiology of chronic cough was established by the development of the Hull Airways Reflux Questionnaire; a validated instrument demonstrating that cough hypersensitivity is usually caused by aspiration of gaseous non acid reflux. The technique of high resolution oesophageal manometry has revolutionised our understanding of the pathophysiology basis of airway reflux.
No less than five new drugs are currently in development and being studied in our Clinical Trials Unit. The importance of reflux, aspiration and lung disease has reached a zenith.
