Previous experimental studies have suggested that the triggering receptor expressed on myeloid cells-1 (TREM-1) is specifically upregulated in the presence of microbial products.
To evaluate the diagnostic value of plasma levels of the soluble form of TREM-1 in patients admitted with clinical suspicion of infection.
Prospective, noninterventional study conducted between July and September 2003.
Medical adult intensive care unit at a university hospital in France.
76 consecutive newly admitted patients who presented with clinically suspected infection and fulfilled at least 2 criteria of the systemic inflammatory response syndrome.
Sensitivity and specificity of plasma soluble TREM-1 levels at admission for the diagnosis of infection. Two independent intensivists blinded to the results of soluble TREM-1 assays retrospectively classified patients as having the systemic inflammatory response syndrome, sepsis, severe sepsis, or septic shock.
The systemic inflammatory response syndrome was diagnosed in 29 patients (38%), and sepsis, severe sepsis, or septic shock was diagnosed in the remaining 47 (62%). A plasma soluble TREM-1 level higher than 60 ng/mL was more accurate than any other clinical or laboratory finding for indicating infection (sensitivity, 96% [95% CI, 92% to 100%]; specificity, 89% [CI, 82% to 95%]; positive likelihood ratio, 8.6 [CI, 3.8 to 21.5]; negative likelihood ratio, 0.04 [CI, 0.01 to 0.2]).
The study did not enroll patients with mild infections not requiring intensive care unit hospitalization, patients older than 80 years of age, or patients who were immunocompromised.
In newly admitted critically ill patients, measurement of plasma levels of soluble TREM-1 could help to rapidly identify those with infection.
