How to take part?

To become a EUSTAR-online centre you need…

1.Access to the internet

2.Positive statement of local ethics committee

3.Email the documents to the EUSTAR secretariat (eustar@unifi.it)

4.→ you will receive your Unique Centre Number and a User Name and

Password (each data entry clerk will get an individual log in, no shared

log ins)

…then

You can enter patients into the database (signed consent of each patient

needed).

Participate myopathy study

Dear EUSTAR member,

You are asked whether you want to participate in the myopathy sub-study. Myopathy is a common and disabling, but often unaddressed problem of patients with SSc.

This study aims to characterise primary muscle involvement in SSc with regard to patient’s history, physical examination including assessment of muscle strength and endurance, laboratory features, and autoantibody status.

Additionally, MRI and/or ENMG and/or muscle biopsy should be performed.

Thus, besides the characterisation of SSc-associated myopathy, this study aims also to identify appropriate diagnostic tools to assess myopathy in SSc patients.

Inclusion criteria are (any one is sufficient for inclusion):• Elevated levels CK or aldolase without obvious explanation

(e.g. extensive exercise, intramuscular injections, muscle injury)

• Proximal muscle weakness on physical examination not explainable by other causes (e.g. neuropathogenic, genetic, metabolic, endocrinologic, infectious disorders, drug-induced, cachexia)

• Muscle atrophy on physical examination not explainable by other causes (e.g. neuropathy, genetic disorders, cachexia)

• Positive myositis-associated autoantibodies (Jo-1, PM-Scl, U1-RNP, Ku, Mi-2, SRP, PL-7, PL-12, OJ, EJ, p155/140, MDA5, NXP2)
