Why do this research?

Lupus or systemic lupus erythematosus (SLE) is a complex and unpredictable disease that can lead to irreversible organ damage. Patients with lupus have specific proteins in their blood that are absent in healthy people. Researchers believe that these proteins could represent a new signal for diagnosing and understanding lupus.  


Our goals are to:

(1) Measure the presence of 10 different specific proteins in this group of lupus patients; (2) define which of the 10 proteins is linked with lupus.  


What will be done?

We will study blood samples and clinical data from a large group of lupus patients followed since the time of their diagnosis at yearly intervals between years 2000 and 2018.  


Who is involved?

Scientists, a biostatistician, a patient representative, and lupus patients.
