    Psoriasis patients show increased platelet aggregation, especially when combined with diabetes. Clearing skin lesions reduced this heightened platelet activity, suggesting a link between skin inflammation and blood clotting.

    Area of Science:

    • Dermatology
    • Hematology
    • Cardiovascular Research

    Background:

    • Psoriasis is a chronic inflammatory skin condition.
    • Altered platelet function has been implicated in various inflammatory diseases.
    • The relationship between psoriasis, diabetes, and platelet aggregation requires further investigation.

    Purpose of the Study:

    • To investigate platelet aggregation levels in patients with psoriasis.
    • To examine the combined effect of psoriasis and diabetes on platelet aggregation.
    • To assess the impact of psoriasis lesion clearance on platelet aggregability.

    Main Methods:

    • Platelet-rich plasma was obtained from psoriatic patients, diabetic patients, and normal controls.
    • Platelet aggregation was induced using adenosine diphosphate (ADP), epinephrine, and collagen.

  • Platelet aggregation was re-measured in a subset of psoriatic patients after their skin lesions cleared.

    • Main Results:

    • Platelet aggregation was significantly higher in psoriatic patients compared to normal controls.
    • A synergistic increase in platelet aggregation was observed in psoriatic patients with co-existing diabetes.
    • Reduced platelet aggregation with ADP and epinephrine was noted after psoriasis lesion clearance.

    Conclusions:

    • Psoriasis is associated with enhanced platelet aggregation.
    • The combination of psoriasis and diabetes exacerbates platelet hyperaggregability.
    • Resolution of psoriatic skin lesions leads to a significant reduction in platelet aggregation, indicating a potential role for skin inflammation in this process.
