Immune Resolution After Staphylococcus Aureus Bacteremia

Running, not enrolling

Conditions studied: Immune Response To Sepsis, Staphylococcus Aureus Infection

In brief

The purpose of this study is to determine how monocyte HLA-DR and other markers of immune function change with time in patients with and without prior immune dysfunction who survive sepsis from Staphylococcus aureus bacteremia. We hypothesize that patients with prior immune dysfunction will have greater reductions in HLA-DR and other markers of immune function after an episode of sepsis than people who do not have prior immune dysfunction.

• WBC less than 4000 cells/mm³ (4 x 109 cells/L) or greater than 12,000 cells/mm³ (12 x 109 cells/L); or the presence of greater than 10% immature neutrophils (band forms)

You may not qualify if…

• Sequential Organ Failure Assessment (SOFA) score > 12 on day of positive blood cultures
• Survival expected to be < 7 days from positive blood cultures
