Platelet Reactivity in Septic Shock

Summary

Coagulation disorders and thrombocytopenia are common in patients with septic shock. Despite the clinical relevance of sepsis-induced thrombocytopenia, few studies have focused on the prediction of thrombocytopenia in this setting. The aim of this study was to evaluate whether platelets aggregometry and markers of platelets activation, such as mean platelet volume or platelet volume distribution width, could predict sepsis-induced thrombocytopenia in patients with septic shock and normal platelet count on the day of diagnosis.

DIAGNOSTIC_TEST

platelet responsiveness evaluation

Blood samples were anticoagulated with 0.129 mmol/L of sodium citrate and then centrifugated for 10 min at 200 rpm; platelets aggregation was assessed with an AggRAM Advanced Modular System light transmittance aggregometer (Helena Laboratories, Beaumont, Texas, USA). Low-molecular-weight heparin (LMWH) was given at least 8 hours before any blood aggregation sample. Agonist used to initiate aggregation test were: -Adenosine diphosphate (ADP) to assess P2Y12-dependent platelet aggregation; (20 ng) - Arachidonic acid (AA) to assess cyclooxygenase-dependent platelet Adenosine diphosphate aggregation (1 mcg) - thrombin receptor-activating peptide-6 (TRAP-6) to assess protease-activated receptor 1-dependent platelet aggregation. Max aggregation reached (Aggmax), the slope of the curve (slope) and the latency time (lat) were analyzed for each agonist.
