Lung transplants represent the last hope for cystic fibrosis patients with end-stage lung disease. However, since the mid-1990s, other than in large research centres, some cystic fibrosis patients were not offered this treatment because of the variable and often poor outcome of surgery. This patient group carried a difficult to treat bacterial infection caused by the Burkholderia genus. In 2001 researchers in Newcastle published findings that demonstrated that one particular species, Burkholderia cenocepacia, was responsible for the poor outcomes and that other species of Burkholderia were not as dangerous. This finding was incorporated into international guidelines and since 2008 most transplant centres worldwide have adopted a risk stratification approach to listing patients for transplant. Consequently, more than 30 people per year worldwide now get transplants that would otherwise have been denied.
Congenital myasthenic syndromes (CMS) are inherited neuromuscular disorders caused by defects at neuromuscular junctions, which are often a result of acetylcholine receptor gene mutations. A subset of CMS patients (around 14% in the US and Europe) have limb-girdle myasthenia (LGM). This disease can be highly disabling with symptoms including increasing weakness of skeletal muscles. As a result of collaborative work between Newcastle and Oxford, it was determined that many LGM patients have a mutation of the Dok-7 gene (unrelated to the acetylholine receptor), and do not, therefore, respond to standard CMS treatments. Since then, a number of additional mutations have been discovered, and genetic testing is now available for the majority of known LGM-causative genes. Crucially, Dok-7 patients, and those with other non-receptor related mutations, can now be diagnosed accurately and treated effectively, with ephedrine and salbutamol (in the US, albuterol). This significantly improves these patients' quality of life by enabling them to walk and breathe unassisted.
Research at the University of Nottingham has defined the clinical phenotype and management of lymphangioleiomyomatosis, a rare and often fatal multisystem disease affecting 1 in 200,000 women worldwide. The group has led the development and evaluation of new therapies and diagnostic strategies which are now part of routine clinical care. The research has underpinned the transformation of this previously under recognised and untreatable disease into a condition recognised by respiratory physicians, with international clinical guidelines, patient registries, clinical trials, specific treatments and a UK specialist clinical service.
Motor neuron disease (MND) is a devastating and debilitating disease with poor prognosis; most patients die from progressive respiratory failure within three years of onset. A randomised controlled trial conducted in Newcastle provided robust evidence that non-invasive ventilation for patients with MND can significantly improve quality of life and increase survival (216 days with non-invasive ventilation compared to 11 days without). Findings from this trial underpinned recommendations concerning the use of non-invasive ventilation in MND in clinical guidelines internationally, and use in clinical practice has increased in the UK, across Europe, and in the US and Australasia. In the UK, the number of MND patients successfully established on non-invasive ventilation in 2009 had increased 3.4-fold since 2000 and since 2009 has further increased almost two-fold.
Neuroblastoma is a paediatric cancer that arises from the sympathetic nervous system. The average age at diagnosis is 18 months and the disease accounts for approximately 15% of all childhood cancer-related deaths. Determining optimal treatment for individual patients is crucial for increasing chances of survival and for reducing side effects of chemotherapy and radiotherapy. Newcastle-led research identified unbalanced 17q gain as the most common segmental chromosomal abnormality (SCA) in patients with neuroblastoma; this was present in more than 50% of patients. Gain of 17q is now one of the key SCAs used to determine treatment for patients in a European neuroblastoma trial and in UK treatment centres. Newcastle research also led to the development of a simple diagnostic test for the detection of the main SCAs in neuroblastoma.
Impact: UoE-developed techniques to determine liver volume and define, pre-operation, the minimum liver remnant required have transformed the viability and success of liver surgery and stimulated commercial development of imaging software/hardware.
Significance: Precise functional liver volume measurement prior to surgery is now the standard of care and, for example, renders 85% of patients previously deemed irresectable to be resectable with a perioperative mortality of 2-4%.
Beneficiaries: Patients with liver cancer; the NHS and healthcare delivery organisations; imaging software/hardware companies.
Attribution: Pivotal studies were led by Wigmore and Garden at UoE.
Reach: Worldwide; technique recommended in guidelines in Europe, N America, Asia, Australasia; deployed in the management of 3600 patients per annum in the UK alone; the use of open-source software increases accessibility in developing world.
Dialysis has revolutionised the management of End Stage Kidney Disease (ESKD), but the benefits of this invasive, demanding treatment may not be clear-cut for elderly, frail patients with other serious comorbidities. University of Hertfordshire and East and North Hertfordshire NHS Trust researchers have led the development of Conservative Management, an alternative to dialysis for some patients, providing multidisciplinary support and careful symptomatic management until death. The research shows that quality of life is maintained, survival may not be significantly compromised, and preferred place of death is more often achieved than for counterparts on dialysis. Conservative Management programmes have been adopted across the UK and elsewhere, influencing the care of many patients.
Between 1996 and 2013 researchers at Swansea University evaluated service initiatives and changing professional roles associated with the management of patients with debilitating gastrointestinal disorders. This work showed the clinical and cost effectiveness of two main innovations: open access to hospital services for patients with inflammatory bowel disease; and increased responsibility for nurses, particularly as endoscopists. Our evidence has had a broad, significant impact on: national policy through incorporation in NHS strategies, professional service standards and commissioning guides; service delivery through the provision of increasing numbers of nurse endoscopists and the wide introduction of nurse-led open access to follow-up; and patient care, as documented in sequential national audits in 2006, 2008 and 2010.
Sudden cardiac death causes 4.5 million deaths worldwide each year many of which could be prevented by implantable cardioverter defibrillators (ICDs), but these also carry risks. Research in the groups of Huang and Grace has led to diagnostic assays offering three times the predictive accuracy of current approaches in guiding cardiologists concerning indications for ICD implantation. The assay has been clinically trialled; since 2008, through the trial, the lives of three patients identified by the assay as at high risk were saved. Further work led by Grace and colleagues provided an improved, subcutaneous ICD (SICD); Grace also participated in a US-based clinical trial (NCT00399217) providing the evidence required for FDA approval supporting also later inclusion into NICE guidance. Since 2008 the SICD has been implanted in over 2500 patients in 16 countries.
Warfarin is an anti-coagulant drug prescribed to tens of millions of people in the UK and US who are at high risk of developing blood clots. Because individual sensitivity to warfarin varies in the population there is a risk of overdosing the drug and causing serious bleeding and even stroke in many people when starting treatment. In 1999 researchers at Newcastle University were the first to demonstrate a statistically significant link between a person's genotype and the appropriate dose of warfarin. In 2010 the US Food and Drug Administration (FDA) mandated inclusion of a table of dose recommendations based on genotype in the warfarin prescribing information leaflet accompanying the drug. Newcastle research forms the basis of the 2009 international standard algorithm for gene-guided dosing of warfarin. This approach has been adopted by large US medical centres and the FDA states that it will prevent 17,000 strokes a year in the US.
