title: Changes in lymphocyte subpopulations and CD3+/DR+ expression in sepsis.
abstract: OBJECTIVE
  To detect lymphocyte subpopulations and CD3+/DR + expression in sepsis.
  
  
  METHODS
  In a prospective clinical study we evaluated subpopulations of lymphocytes and percentage of CD3+/HLA-DR+ lymphocytes using two-color flow cytometry in 40 patients with sepsis and compared them with 34 healthy adults.
  
  
  RESULTS
  Septic patients, when compared with healthy controls, have significantly lower percentage and absolute numbers of total T lymphocytes and CD4 T lymphocytes (P < 0.01). Absolute numbers of CD8 T lymphocytes, NK cells, CD3+/DR + lymphocytes and CD4/CD8 ratio were also decreased (P < 0.01). The percentage of B lymphocytes was increased (P < 0.01).
  
  
  CONCLUSIONS
  Our results are in agreement with previous findings in patients with sepsis after major surgery or trauma. The decreases in the percentage and absolute numbers of circulating lymphocyte subsets in non-surgical sepsis could represent a general reaction to stress. Increased percentage of B lymphocytes is most probably related to the bacterial etiology of the disease.
