Key result
Vasculitis is linked to ~13-fold higher plasma thrombospondin levels, reflecting intravascular platelet activation.
Why the study?
Plasma thrombospondin concentration was investigated as a potential indicator of intravascular platelet activation in patients with vasculitis.
Does measurement of plasma thrombospondin improve detection of intravascular platelet activation in patients with vasculitis?
Case-Control (n=53)
Does measurement of plasma thrombospondin improve detection of intravascular platelet activation in patients with vasculitis?
Absolute Event Rate: 791% vs 59%
Plasma thrombospondin is elevated in patients with vasculitis and correlates with beta-thromboglobulin, suggesting it may serve as a better indicator of intravascular platelet activation due to its longer half-life.

Elevated TSP may signal platelet activation in vasculitis; leaves open its diagnostic utility pending validation.
McCROHAN et al. (1987) conducted a case-control in Vasculitis (n=53). Vasculitis vs. Control individuals was evaluated on Plasma thrombospondin (TSP) concentration. Patients with vasculitis had substantially higher mean plasma thrombospondin concentrations (791 ng/ml) compared to control individuals (59 ng/ml), indicating intravascular platelet activation.
