Absolute lymphocytosis associated with nonsurgical trauma

Area of Science:

• Medical Science
• Hematology
• Trauma Care

Background:

• Absolute lymphocytosis can occur after trauma, but its prevalence and temporal course are not well-defined.
• Understanding lymphocytosis in trauma patients is crucial for accurate diagnosis and management.

Purpose of the Study:

• To investigate the occurrence and pattern of absolute lymphocytosis in patients experiencing nonsurgical trauma.
• To determine the contribution of trauma to overall cases of lymphocytosis.

Main Methods:

• Analysis of lymphocyte counts in three patient groups: mild-to-moderate trauma survivors, severe trauma patients in intensive care, and a hospital-wide survey of lymphocytosis cases.
• Comparison of admission lymphocyte counts with counts taken within hours or 24 hours post-trauma.

Main Results:

• Thirteen of 64 mild-to-moderate trauma patients exhibited admission lymphocytosis, with counts decreasing significantly within 24 hours.
• Eleven severe trauma patients showed a rapid decrease in lymphocyte counts within six hours.
• Trauma and hemorrhage accounted for 16% of all lymphocytosis cases, indicating trauma as a common cause.

Conclusions:

• Nonsurgical trauma is frequently associated with absolute lymphocytosis.
• This lymphocytosis typically transitions to lymphopenia within hours of the traumatic event.
• Trauma, alongside other acute stresses, represents a significant cause of lymphocytosis in hospitalized patients.
