Scleroderma, also called systemic sclerosis, is a complex and serious rheumatic disease that affects much more than the joints and muscles. Unfortunately, many patients develop scarring and inflammation in the blood vessels, lungs, kidney, and intestinal tract. This leads to problems that can be life threatening including pulmonary fibrosis, pulmonary hypertension, and renal failure.
Fortunately, research efforts have improved the outcome for patients and work led by the Royal Free London and University College London has underpinned the progress.
The Royal Free Charity has provided generous support for research, patient care and education in scleroderma. Our unit cares for well over 1,000 patients with this rare disease and is the largest centre in the UK and one of the leading centres internationally. There are strong links with research scientists at UCL and with many key clinical services at RFL including plastic surgery, cardiology, pulmonary hypertension, respiratory medicine, nephrology, dermatology and gastroenterology.
Highlights and projects that are being undertaken include:
- Stem cell transplantation: For some patients at risk of severe internal organ disease autologous stem cell transplantation has emerged as a treatment. Unfortunately, it is very intensive and sometimes recipients do not survive the treatment to gain the long-term benefit. Recently we have hosted a visiting fellow form Utrecht, a lead centre in Europe with unrivalled experience and expertise. This allowed us to optimise our patient assessment and approach to align it with the best international standards.
- Better prediction of life-threatening complications: One of the challenges of systemic sclerosis is that development of major heart, lung or kidney complications is hard to predict. We have worked on integrating routinely collected clinical information for lung and heart tests and developed new blood tests (called biomarkers) to predict complications before they develop, or at an earlier stage when treatment may be more effective. One key project called MODERNISE Scleroderma will develop new ways of harnessing and integrating data to improve risk prediction for patients.
- Development of new medical and surgical therapies: The Royal Free Centre, linked to the new NIHR Royal Free Clinical Research Facility and the ongoing research laboratories, including collaborations across UCL, is at the frontline in testing new treatments. Globally, three drugs have been approved for systemic sclerosis or scleroderma associated lung fibrosis in the past two years and Royal Free Hospital has been involved in key trials of all these agents. New drugs are emerging, but additional research funding can help to unlock the full potential and permit exciting scientific studies that will unravel the mechanisms of systemic sclerosis and lead to the next trails to try and achieve the benefit of stem cell transplantation without its associated risk. In addition, we have the largest programme for “autologous fat transfer” led by Professor Peter Butler, that represents a uniquely effective treatment for facial fibrosis that has not previously been treatable.
- Unravelling the gut in scleroderma: We are very grateful for donations to the Royal Free Charity that have specifically supported research into the intestinal complications. This has already led to new research and better understanding of patients at most risk and we also are gaining insight into new disease mechanisms and moving to test effectiveness of emerging drugs. Gut complications impact quality of life and can be life-threatening and represents a major unmet need.
Donated funds have helped cover the relatively modest costs of small pilot studies looking at the possible factors underpinning the link between fibroblast activation and tissue damage that we think may underlie progression of fibrosis in the skin and lungs. We have been able to undertake some new work that hopefully will allow us to secure a larger research grant to support laboratory studies.
