  • Research summary

    Cough is a very common and often unpleasant symptom. Most coughs are short-lived but others may indicate serious disease. Persistent coughs effect up to 16% of the population and can have a significant negative impact on quality of life. Coughing is also important in the spread of infectious disease such as tuberculosis and measles.

    Although several billion pounds are spent worldwide each year on over-the-counter cough remedies no potential cough suppressing medication has been shown to be effective. Up to 40% of patients referred to secondary care because of persistent coughs remain without a diagnosis or definitive treatment.

    Cough is only just beginning to attract attention as a topic for research. The direct causes of cough and its variation between and within diseases have been little explored. Two genes have been identified whichseem to be involved: TRPV1, which is involved in the cough reflex, and MUC5AC, involved in mucous production. By taking saliva samples from patients troubled with coughs we would like to learn more about the influence of these genes. This could lead to personalised treatments for cough and improved understanding of the infectiousness of tuberculosis.
    The study will recruit mainly at the Homerton University Hospital but possibly other hospital sites in London. It is funded by the NIHR CCRN.
