Introduction:

sepsis is a deadly and common disease. It’s one of the few medical conditions that attack’s the same and with great ferocity both populations with scarce resources as much as populations with high incomes. In patients with an inflammatory process, the rise in the concentration of proinflammatory cytokines could lead to a release of platelets, which leads afterwards to a diminish in the platelet count and inversely to change in the platelet morphology (rising the size to variable values of mean platelet volume (MPV). It is important to determine early biomarkers that helps identify with an easy and economic way to facilitate detection and help predict mortality.

Objective:

determine the mean platelet volume as a biomarker of inflammatory response as an early indicator of mortality in patients infected with COVID-19.

Material and methods:

a cohort, observational, prospective, comparative and longitudinal study was carried out.

Results:

a MPV ≥ 7.4 fL did increase mortality 3.1 times between the selected patients (IC of 95% 1.3 - 7.5, p = 0.016).

Conclusion:

COVID-19 behaves like an infection that can involve multiple organs or systems of the host. Many studies suggest that hematologic profiles change during the course of the SARS-CoV-2. The production of platelets rises as it decreases the platelet count. Nevertheless, more studies are needed that allow us to clarify this mechanisms.
