Polymyositis (PM), dermatomyositis (DM) and inclusion body myositis (IBM)belong to a group of inflammatory muscle disorders, of unknown cause, that are characterised by skeletal muscle inflammation and progressive muscular weakness, which can be debilitating and chronic in nature (occasionally fatal).
The current treatment options for these conditions are steroids and various other immunosuppressive drugs. However, these are usually only partially effective at reducing symptoms, and their toxic side effects also limit their usefulness. In order to develop more specific treatments for myositis in the future (and therefore more effective), it is important to understand the exact mechanisms that cause the disease in the first instance. In other similar inflammatory diseases such as rheumatoid arthritis (RA) and systemic lupus (SLE), it is known that changes to the Human Leukocyte Antigen(HLA), as well as certain inflammatory cytokines, are involved in both the development and expression of the disease.
As many of the inflammatory mechanisms that cause damage in PM, DM and IBM are similar to those in RA and SLE, it seems likely that similar genetic factors will also be involved in the development and expression of PM, DM and IBM.
In order to understand the genetic aspects / causes of myositis, and ultimately develop more effective treatment therapies in the future, patients with PM, DM or IBM, will be asked to give 20 mls of blood. These blood samples, along with the patient's clinical details, will then be sent to the Centre for Integrated Genomic Medical Research (CIGMR), at The University of Manchester, where all of the genetic analyses will take place. By understanding the genetic cause of the disease, it should be possible to design specific drugs for treating the condition in the future.
|Condition or disease||Intervention/treatment|
In order to understand the genetic aspects / causes of myositis, and ultimately develop more effective treatment therapies, it will be necessary to collect blood samples and clinical details from around 1000 patients with myositis. As the condition is very rare, it will not be possible to get the required number of patients from one centre alone, and therefore, a collaborative, multicentred approach will be needed. Consultant rheumatologists and neurologists throughout the UK, who have patients with PM, DM or IBM, will be approached, and asked if they would like to officially enter into the myositis genomic multicentred study. Once ethical and R&D approval has been granted, consultants will be named as the 'Principal Investigators' at each of these 'research sites' and could then start to recruit suitable patients into the study.
Patients from each research site, with definite PM, DM or IBM, will be asked by their own consultants (Principal Investigator) to give 20 mls of blood via venepuncture for genetic and antibody analysis. The PI will also complete a clinical/laboratory proforma, for each patient, regarding their disease characteristics, to allow subsequent confirmation that patients' disease is indeed definite, and this proforma and the blood sample will be sent to CIGMR. All of the genetic analyses, will take place at CIGMR, but storage of clinical details and certain patient identifiers will be stored at SRFT on a password protected NHS tust computer.
This study will be co−ordinated by Dr RG Cooper through the Rheumatic Diseases Centre, Salford Royal NHS Foundation Trust (SRFT), and Professor Bill Ollier from the Centre for Integrated Genomic Medical Research unit (CIGMR), Stopford Building, Manchester University.
