Introduction:
sP-selectin is a glycoprotein located in α granules of platelet and endothelial's Weibel Palade body, as expression to platelet activation and endothelial cell stimulation by SARS-CoV-2 binding with ACE2 receptor. Consumptive thrombocytopenia is also related to platelet activation. Elevation of sP-selectin and thrombocytopenia are related to COVID-19 complication and often correlated with severity of COVID-19.
Purpose:
Assess the correlation between sP-selectin and platelet in COVID-19 patients at intensive care and non-intensive care.
Patients And Methods:
The study population was hospitalized COVID-19 patients confirmed by Real-Time PCR that underwent platelet examination within 48 hours upon admission, divided into intensive care and non-intensive care group. sP-selectin examination using ELISA methods. Platelet cell count and sP-selectin divided based on normal reference range.
Results:
The subjects consist of 24 were in intensive care, 25 were in non-intensive care group. A 66.7% of subject in intensive care group has an elevation in sP-selection (>44.0 ng/mL). Thrombocytopenia was significantly correlated with intensive group (r =-0.32, p<0.05). The combination of platelet count <150.000/mm3 and sP-selectin >44.0ng/mL was not correlated with the intensive and non-intensive group. Platelet and sP-selectin were not correlated with each other.
Conclusion:
Thrombocytopenia is able to induce the expression of sP-selectin.
