Abstract

Background: Trauma in its early stages leads to an acute inflammatory condition affecting all cellular lines. Neutrophil granulocytes make up the largest population of human white blood cells and are fundamental to the innate immune system. The objective of our pilot study was to evaluate neutrophil death and viability alterations in critically ill trauma patients in correlation with their clinical outcome.

Material and method: Critical ill trauma patients were enrolled in the study. In order to assess alterations in cellular death, blood samples were drawn using EDTA containing tubes and analyzed in the first twenty four hours after admission, then after forty eight and seventy two hours. Annexin V was used as a marker for apoptotic cells and propidium iodide for necrotic cells.

Results: The first two cases exhibited an increase in cellular viability by the second day as shown by a small increase in neutrophil apoptosis and a decrease in neutrophil necrosis. These patients progressed to a positive clinical outcome. The second two cases showed slight modifications in either physiological or pathological cellular death, and increasing levels of cellular necrosis. These patients progressed to a negative clinical outcome.

Conclusions: These cases suggest that neutrophil cell viability and death were associated with the patient’s clinical outcome.

Abstract

Trauma affects the activity of the innate immune system. The objective of this case report is to present the case that prompted us to analyse all the peripheral white blood cell lines. A 19 year old male patient was admitted to the Intensive Care Clinic with severe head trauma. The final diagnosis was set to be severe cerebral trauma with subarachnoid hemorrhage, right frontal and temporal cerebral contusions, diffuse cerebral edema, left parietal and temporal fracture, sphenoid hemosinus and right sided lung contusions.

Material and Method: Whole blood was immediatly analyzed by flow cytometry for leukocytes. Apoptosis was detected with Annexin V, necrotic cells were stained with propidium iodide. Samples were drawn three consecutive days.

Results: Lymphocytes, monocytes and granulocytes all showed marked increase in viability and decrease in necrosis during the biological monitoring in correlation with a positive clinical outcome. The most important changes were noted in the monocyte population.

Discussion: Although we started out monitoring neutrophil viability and death, this particular case prompted us not to overlook other leucocyte populations.

Conclusion: The apparent positive relationship between this patient’s positive clinical outcome and cellular viability and death changes is promising but they warrant further study.
