Kinetics of C-Reactive Protein in Giant Cell Arteritis Following Glucocorticoid Initiation: A Pilot Study (GIDEON) (GIDEON)
Kinetics of C-Reactive Protein in Giant Cell Arteritis Following Glucocorticoid Initiation: A Pilot Study
We propose to analyze the kinetics of the main marker of inflammation in GCA in order to understand its links with initial clinical manifestations and the possible appearance of complications and/or relapses.
Early assessment of the rate of CRP normalization would enable us to adapt the therapeutic strategy in order to avoid complications and/or relapses.

详细说明
Giant cell arteritis (GCA) is a chronic systemic vasculitis of the large vessels characterized by a significant inflammatory syndrome, correlated with disease activity and various inflammatory biomarkers, including CRP, which more effectively reflects disease activity.
Relapses remain frequent, with rates of up to 45.7%. Recommended treatments involve long-term corticosteroid therapy and/or sparing therapies, which are associated with adverse events.
Identifying relapsing patients is therefore crucial, in order to best adapt initial treatment and patient follow-up.
We therefore propose to study CRP kinetics at diagnosis and at initiation of corticosteroid therapy, to determine the link with disease progression.
