The influence of sepsis on erythrocytes morphology: case report and literature review

Abstract

This paper highlights a clinical case of sepsis caused by soft tissue infection. Peripheral blood smear, plasma value of inflammatory biomarkers and the white blood cells count were performed. Significant morphological changes were revealed through peripheral blood smear test two days after patient admission. Patient developed septic shock after the third day in intensive care unit (ICU). Laboratory results showed major morphological changes (erythrocytes deformity, abnormal neutrophils); these were correlated with elevated plasma value of interleukin-6 and procalcitonin.
