Juvenile Dermatomyositis Cohort Biomarker Study and Repository (UK and Ireland) (JDCBS)
Research into childhood myositis.
Diseases that cause inflammation of the muscles (known as myositis) are rare but serious. The most common form of childhood myositis is juvenile dermatomyositis (JDM). JDM affects about 3 children in every million. Because myositis in children is so rare there is a lack of evidence for best ways to treat it. To overcome, this in the UK, a network of researchers, scientists, nurses, physiotherapists and doctors who work with children with myositis agreed to work together, and this has led to a large, powerful collection of cases of childhood myositis each with data and samples stored. This study is called the Juvenile Dermatomyositis Cohort Biomarker Study and Repository (UK and Ireland) (JDCBS).
In the past a research bottleneck existed due to a lack of adequate standardized clinical data linked to biological samples in sufficient numbers for research: collaborative networks such as this directly address this need. It is therefore seen to be a highly valuable resource for research by researchers in the field and has already been used to make several breakthrough discoveries in myositis. The JDCBS has recently been awarded peer reviewed grant funding from several bodies including the Wellcome Trust and Action Medical UK. The Chief Investigator of the JDCBS is Professor Lucy Wedderburn Institute of Child Health UCL London. The JDCB study has full ethical approval and all children and families are recruited with informed consent. All the data are stored in an anonymous fashion in a secure, protected database with full security and compliant with the Data Protection Act. New projects or proposals may require amendment or extension to the existing ethical approval as appropriate.
Projects already started or published which have been made possible through the existence of the JDCBS have included studies on clinical treatments, physiotherapy, new drugs for JDM, the best way to analyse muscle biopsy tissue from children with JDM, antibodies in JDM and how they relate to immune system (HLA) genes affecting the subtype of myositis, as well as other genes that may play a role in JDM, how blood vessels may be altered in JDM and many others. For more details on current and previous projects please see below.

Are you interested to know more or propose a research project?
In addition to members of the JDRG, researchers who are interested in myositis are very warmly encouraged to contact the JDRG and JDCBS about possible projects, or collaborations. The JDCBS is run by a steering committee, which includes an independent chair (Mr Ian Roberts) and advisors, and also patient/parent representation. One of the key roles of this Steering Committee is to consider all collaborations and applications for use of the JDCBS data and or samples. Each research project requesting to use the Cohort study usually needs to obtain research funding and may need to obtain specific amendments to existing ethical approvals. If you are a researcher or interested party and would like to know more about the JDCBS and the application procedure to the Steering Committee please contact the JDRG Administrator at firstname.lastname@example.org
