It is possible that alterations in cell populations variations in effector molecules and the degree of apoptosis differ between sepsis caused by ventilator-associated pneumonia VAP and non-VAP sepsis. VAP is one of the most common infections and leading causes of sepsis in the intensive care unit and mortality remains high. A better understanding of the unique pathophysiologic features of VAP is needed in order to develop interventions that target those specific pathways. Ventilator-associated pneumonia VAP develops commonly in mechanically ventilated patients and is a major cause of morbidity and mortality in the intensive care unit. In a study published in this issue of Critical Care Pelekanou and colleagues 1 investigated the differences in innate and adaptive immune responses in 36 septic patients with VAP and 32 patients with sepsis due to other infections like pyelonephritis bacteremia intra-abdominal infection and community- and hospital-acquired pneumonia. There was evidence of a more pronounced immunoparalysis in patients with VAP than in those with other bacterial infections. This was supported by the decreased number of CD3 CD4 cells the increase in monocyte apoptosis and the lower release of .
