Table 2.
Flow-cytometric data of patients with sepsis due to VAP and sepsis caused by other nosocomial infections.
| VAP | Other infections | P | |
|---|---|---|---|
| CD3(+)/CD4(+) | 208.52 (192) | 280.68 (508.7) | 0.034 |
| CD3(+)/CD8(+) | 114.8 (123.26) | 102.49 (244.7) | 0.787 |
| CD3(+)/CD(16+56)(+) | 18.09 (34.41) | 15.11 (49.49) | 0.940 |
| *Natural killer cells | 26.98 (62.94) | 39.61 (45.22) | 0.463 |
| CD19(+) | 28.00 (70.00) | 37.93 (33.82) | 0.219 |
| Annexin(+)/CD4(+)/PI(-) | 3.16 (4.48) | 2.33 (7.64) | 0.944 |
| Annexin(+)/CD8(+)/PI(-) | 3.74 (8,71) | 6.47 (15.71) | 0.269 |
| Annexin(+)/PI(-) of isolated monocytes | 20.62 (28.11) | 12.19 (22.98) | 0.007 |
*Natural killer cells were defined as CD3(-)/CD(16+56)(+). Values are expressed as median (IQR) absolute numbers for CD3(+)/CD4(+), CD3(+)/CD8(+), CD3(+)/CD(16+56)(+), natural killer and CD19(+) cells and as median (interquartile range) percentages for Annexin(+)/CD4(+)/PI(-), Annexin(+)/CD8(+)/PI(-) and Annexin(+)/PI(-) of isolated monocytes. VAP = ventilator-associated pneumonia.
