Abstract:
OBJECTIVE To evaluate the value of serum procalcitonin(PCT) levels for differentiating Gram-positive and-negative bacteria infected critically ill patients in intensive care unit(ICU). METHODS Serum PCT levels were measured in 80 patients with sepsis and severe sepsis in ICU.Of the 80 patients,40 were infected with Gram-positive bacteria and 40 were infected with Gram-negative bacteria.Another 40 patients with fungi or viruses infection or non-infection from ICU were measured in parallel as control. RESULTS Serum levels of PCT in patients with Gram-negative bacteria were significantly higher than in those with Gram-positive bacteria and control ones(18.5?5.8ng/ml vs 3.9?2.1ng/ml and 0.3?0.2 ng/ml,respectively,P
