Personalised Medicine

Personalised Medicine; sometimes called Stratified or Precision Medicine classifies individuals or subpopulations of patients that differ in their susceptibility to a particular disease or their response to a particular treatment. The “one size fits all” approach to patient treatment is increasingly recognised as being both ineffective and costly.

Stratified or Personalised Medicine ensures that patients receive the most appropriate treatment at the right time. Patient classification can be based on demographic and disease phenotypes (physical or biochemical characteristics) or biomarkers (biological indicator such as a blood test).

The University of Leicester have a long-term focus on Stratified and Personalised Medicine that is carried out in different disease areas, across different research themes.

Stratified and Personalised Medicine Research in Leicester can be found within the NIHR Biomedical Research Units (BRUs) in Leicester Hospitals including the Respiratory BRU.

Much of the work carried out by the Respiratory Theme falls under the description of Precision Medicine. Examples include:


Exhaled breath contains >1500 volatile organic compounds (VOCs) reflecting biological processes occurring within the lung as well as host-environment interactions [1]. Analysis of VOCs in breath is a metabolomic approach that provides a real-time, non-invasive method of diagnosing, phenotyping and stratifying patients with a variety of clinical conditions including respiratory disease and infections (bacterial, fungal, viral). Leicester has unique strengths and strong collaborations between clinical academics and basic scientists and SMEs, delivering novel prognostic tests and targeted therapies.

Studies into the role of fungal allergy in respiratory disease

This involves using appropriate biomarkers to determine which types of asthma are associated with fungal allergy, how this relates to day to day control and prognosis and whether fungal specific interventions are of value in treating these patients.

Chronic Obstructive Pulmonary Disease

Exacerbations of chronic obstructive pulmonary disease (COPD) are associated with significant morbidity and mortality. Current guidelines advocate the use of systemic corticosteroids in addition to antibiotics to treat an exacerbation, but these treatments are not universally effective and are not without harm. Individualised treatment may, therefore, be an advance. The Respiratory Medicine group recently showed that patients with a peripheral blood eosinophil count of ≥2% respond promptly and completely to prednisolone, whereas those with a count of <2% had a higher rate of treatment failure compared with placebo. This has led to alrger studies to confirm this stratified treatment approach.

Genetics and Genomics of COPD

Professor Martin Tobin’s work involves identifying individuals with rare genotypes of COPD which will help the Respiratory Science Theme understand the mechanisms of lung function decline in asthma and COPD.
