King's College London (KCL) researchers contributed to the discovery that increased C fibre nerve activity in the bladder is a major cause of overactive bladder (OAB) syndrome. Based on this insight, KCL researcher Professor Dasgupta, a surgical urologist at Guy's Hospital, and his team pioneered a new surgical technique for micro-injecting Botulinum Toxin-A (BTX-A) directly into the bladder to suppress C fibres and improve bladder control. The KCL team then conducted the world's first successful clinical trials into the minimally invasive injection of BTX-A n OAB patients. These trials received significant international media coverage. This cost-effective OAB therapy is now licensed by the EU and FDA, is recommended in national and international guidelines, and has significantly improved the treatment of a common health problem.
King's College London (KCL) research has made a major contribution to improving the quality of life for patients who have anaemia linked with chronic kidney disease. Studies undertaken by KCL researchers established that intravenous iron supplementation was required in anaemic patients with advanced kidney disease, in whom oral iron therapy was ineffective, and defined the best regimes for administration of intravenous iron. Subsequent KCL work on drugs that stimulate production of red blood cells (erythropoiesis) defined the target levels of haemoglobin to aim for in chronic kidney disease patients. Most recently, KCL researchers made the key discovery that the novel drug peginesatide for the first time enables the rescue of patients who develop a rare and potentially fatal reaction against erythropoietin (which is the commonest treatment for anaemia in chronic kidney disease). These KCL research studies have had a significant impact by making a major contribution to national and international clinical guidelines, including UK NICE guidelines and the 2012 National Kidney Foundation KDIGO Clinical Practice Guideline for Anemia in Chronic Kidney Disease.
Acute promyelocytic leukaemia (APL) is of interest because it is the first cancer that can be cured with drugs that target a unique molecular abnormality. KCL research has developed accurate molecular techniques which are essential to diagnose the disease, guide treatment, and monitor for relapse. Sub-microscopic levels of leukaemic cells remaining in the patient's bone marrow after treatment (referred to as `minimal residual disease') give an early warning of re-occurrence of the disease. Our laboratory has developed sensitive tests for these cells, allowing treatment to be tailored to individual patient needs. This has had a major impact on APL diagnosis and monitoring and has been incorporated in national and international disease-treatment guidelines.
King's College London (KCL) researchers were the first to identify that an early sign of diabetic kidney disease was the presence of albumin in the urine, a condition known as albuminuria. Building on this finding, the KCL Unit of Metabolic Medicine designed and led in-house, national then international randomised controlled clinical trials with the aim of preserving kidney function in diabetic patients. Ultimately, KCL research established that several drug inhibitors of the renin-angiotensin-aldosterone system (RAAS) can control albuminuria, slow the deterioration of kidney function and significantly extend survival rates in diabetic patients. These drugs are now generically available, and their prescription is recommended by current international clinical guidelines across North America, Europe, Australia and Asia. This shows major impact in terms of reach and significance.
The use of a formulary to influence prescribing practice is common, with almost all hospitals possessing one that attempts to provide advice on the safe, effective and economic use of medicines. The Maudsley Prescribing Guidelines to Psychiatry steps beyond the function of a mere formulary and provides evidence-based guidance on the use of psychotropic medicines that influences prescribing on both a national and international basis. Now in its 11th Edition and translated into nine languages, much of the evidence in The Guidelines is generated by King's College London research. Additionally, this research is used in other guidelines, in clinical handbooks and in prescribing practices around the world.
King's College London researchers have had a major widespread impact on medical care for people with dementia. They have demonstrated the limited benefit and considerable harm done by the use of antipsychotics in dementia patients. Their follow-on campaigning and policy work brought this major health issue to the forefront of the political agenda and led them to work with the Department of Health to create a best practice guide, now widely used nationally and internationally. In addition, they have worked with the BMJ to develop an e- learning package for General Practitioners. The combined impact of this work has made a major contribution to a 60% reduction in the use of antipsychotic drugs in people with dementia in the UK and major changes in practice internationally, preventing 1000's of unnecessary deaths.
King's College London (KCL) researchers developed cognitive behaviour therapy for psychosis (CBTp), which is now a National Institute for Health and Care Excellence-recommended psychological intervention. CBTp is now part of routine NHS treatment and an estimated 25,000 patients in England and Wales receive it annually. Implementation of CBTp has been steered by KCL researchers' involvement with the Government's Increasing Access to Psychological Therapies — Severe Mental Illness initiative. The KCL model for CBTp has been used to develop clinics in Australia and the US and information on this therapy is disseminated via a KCL-led website.
The University of Oxford's International Subarachnoid Aneurysm Trial (ISAT) changed clinical practice worldwide by showing that endovascular coiling is a more effective and safer treatment than neurosurgery following subarachnoid haemorrhage, with fewer complications and improved quality of life. Subarachnoid haemorrhages account for 1 in 14 strokes and are caused by bleeding in and around the brain; approximately 85% occur when cerebral aneurysms rupture. ISAT was the first trial to compare neurosurgery, or neuroradiological endovascular coiling in patients with ruptured cerebral aneurysms causing acute subarachnoid haemorrhage.
An estimated 1% of UK adults suffer from rheumatoid arthritis and the long-term pain and disability associated with it, Historically, however, treatments focused on relieving symptoms and did not control the arthritis itself or prevent disability. An extensive series of clinical trials and associated research programmes at King's College London (KCL) over 20 years has now significantly improved treatment recommendations and thus quality of life for thousands of rheumatoid arthritis patients in the UK, Europe and other countries. Multicentre trials of intensive treatments using conventional drugs have extended the range of drugs available, established the effectiveness of early intensive treatment, and shown that early combination therapies are safe.
In the last two decades researchers at King's College London (KCL) have revolutionized the management of benign surgical salivary disease (obstruction and tumours). Understanding the pathophysiology of the salivary glands has translated into a complete change of treatment away from traditional gland removal to minimally invasive gland preserving management. In obstructive disease >90% of stones can be released and <3% of glands removed. Similarly most parotid tumours can be removed safely by extracapsular dissection preserving the gland and significantly reducing risk of facial nerve injury. In children, >80% of childhood ranulas now can be treated without sublingual gland removal. KCL's Dental Institute has become a UK referral centre for minimally invasive salivary procedures and the procedures are now used worldwide.
