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.
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.
Research conducted by Professor Tim Goodship and co-workers at Newcastle has had a profound effect on the prognosis for patients with atypical haemolytic uraemic syndrome (aHUS). By engaging in research on the genetic factors underlying the disease they developed an understanding of the molecular mechanisms responsible. Identifying that the majority of patients with aHUS have either acquired or inherited abnormalities of the regulation of complement (part of the immune system) led to the establishment of a UK national service for genetic screening and treatment with the complement inhibitor eculizumab. As eculizumab is now available to patients in England, the progression to end-stage renal failure can be prevented and patients already on dialysis will soon be successfully transplanted.
Researchers at the University of Manchester (UoM) have made a significant impact nationally and internationally on improving the outcome for children with acute lymphoblastic leukaemia (ALL) (~450 pa in the UK). The changes in clinical practice based on our research are now national standards of care for children with de novo and relapsed ALL in the UK and Ireland. Other international groups have adopted key findings from the results of our frontline trials. Our relapse protocol for childhood ALL underpins European and North American strategy for the management of relapsed disease.
COPD affects up to 3.5 million people in the UK and costs the NHS £700m pa. Over the last 15 years, research by Professor Calverley and colleagues at the University of Liverpool (UoL) has impacted significantly on the care of COPD patients. Specifically, this group showed that routine testing of COPD patients for the presence of bronchodilator reversibility was unreliable and did not predict clinical outcomes. This changed international guideline recommendations in 2007 and the Quality Outcomes Framework payments to GPs in 2009. They showed that oral corticosteroids accelerated recovery from exacerbations and that anti-inflammatory drugs, whether inhaled corticosteroids or PDEIV inhibitors, reduced exacerbations by 25% with a subsequent fall in the number and length of hospitalisations. This led to changed NICE guidance for corticosteroids in 2010 and drug registration with EMA and FDA for the PDEIV inhibitor treatment in 2011. Treatment in UK and Western Europe has changed as a result of this research.
Prior to the change in WHO recommendations which occurred following this study many patients in Africa and other developing countries were receiving an inferior regimen for the management of tuberculosis, a consequence of which meant that many had to be retreated. Since the implementation of the revised WHO Guidelines in 2010 almost all countries have now switched to the gold standard tuberculosis treatment regimen based on 6 months of isoniazid and rifampicin
Trauma is a rapidly increasing global healthcare problem which is predicted by the World Health Organisation (WHO) to overtake infectious disease globally by 2020. The discovery of the acute coagulopathy of trauma (uncontrolled bleeding) and the subsequent establishment of the clot stabiliser tranexamic acid (TXA) as a treatment for this condition has led to a change in national and international trauma management protocols. British armed forces and the US military implemented the use of the drug soon after the results were published. Every injured British or American soldier now receives this treatment. The use of TXA has been included in national and international guidance for trauma care.
Impact: Health and welfare; a clinical trial demonstrated that statin therapy is ineffective in aortic stenosis; this informed international guidelines and changed clinical practice.
Significance: Unnecessary statin therapy is avoided in up to 500,000 people in the UK alone, saving the NHS £169M p.a. Known statin side-effects of myalgia or hepatic dysfunction are avoided in 30,000 patients.
Beneficiaries: Patients with aortic stenosis; the NHS and healthcare delivery organisations, the economy.
Attribution: Newby and Boon, UoE, undertook the first investigator-led randomised controlled trial of statin therapy in aortic stenosis: the SALTIRE trial.
Reach: Aortic stenosis affects 2% of people over 65. The SALTIRE trial results informed European and N American guidelines and have impacted the treatment of millions of people globally.
A Cardiff researcher has led an International 15 year programme resulting in multiple novel findings which have led to changes in the recommended diagnosis and treatment of acquired haemophilia A (AHA). The research has, for the first time, allowed the comparison of immunosuppressive regimens for inhibitor eradication and comparison of the efficacy of treatment strategies to control bleeds. Studies led directly to the production of UK and International guidelines on the management of AHA with 14 of the 18 specific recommendations in the UK guideline being underpinned by Cardiff-led research.
Research at UCL firmly established tacrolimus as the optimal calcineurin inhibitor to use in immunosuppressive regimens following liver transplantation. Compared to ciclosporin its use improved graft survival by 6% and patient survival by 7%. Assuming 550 liver transplants per year in the UK since 2008, we can estimate that, with 90% of patients treated with tacrolimus and 10% ciclosporin, tacrolimus-based immunosuppression has resulted in 165 grafts and 192 lives being saved during the period 2008-13.
