Sažetak
Background. The aim was to examine the diagnostic value of serum and bronchoalveolar lavage (BAL) fluid levels of procalcitonin (PCT), interleukin- 6 (IL-6) and triggering receptor expressed on myeloid cells-1 (TREM-1) in patients with ventilator-associated pneumonia (VAP) caused by bacteria. Methods. The study included 31 surgical intensive care unit (ICU) patients with VAP and 52 ICU patients without VAP. The concentrations of PCT, IL-6 and TREM-1 were determined in serum and BAL fluid from patients with VAP and in serum of no VAP patients. PCT was determined with an immunofluorescence assay (KRYPTOR, BRAHMS, Germany). IL-6 was measured with a chemiluminescent enzyme immunoassay (IMMULITE1000, Siemens, Germany). TREM-1 was determined with an enzyme-linked immunosorbent assay (R&D systems, Minneapolis, USA). Results. In serum, the medians of PCT, IL-6 and TREM-1 concentrations were significantly elevated in patients with VAP compared with no VAP patients: 0.680 vs 0.055 ng/mL, P<0.0001 (PCT) ; 343 vs 85 pg/mL, P=0.0006 (IL-6) ; 75.6 vs 39.5 pg/mL, P=0.0010 (TREM-1). In BAL fluid samples from patients with VAP, PCT concentrations were extremely low (0.020 ng/mL, 95%CI 0.02-0.04), IL- 6 concentrations were significantly lower than in serum (92.8 pg/mL, 95%CI 56-355, P=0.008), while TREM-1 concentrations were significantly higher than in serum (408 pg/mL, 95%CI 290-544, P<0.0001). Conclusions. Serum concentrations of PCT, IL-6 and TREM-1 have been significantly increased in patients with VAP caused by bacteria. However, in BAL fluid only TREM-1 receptor has been shown as useful in the diagnosis of VAP, suggesting bronchoalveolar TREM-1 level to be a potential marker of bacterial pulmonary infection.
