Clinical relevance of procalcitonin and C-reactive protein as infection markers in renal impairment: a cross-sectional study.
    Critical care (London, England), 2014, Nov-19, Volume: 18, Issue:6

    Although the clinical application of procalcitonin (PCT) as an infection marker in patients with impaired renal function (estimated glomerular filtration rate (eGFR) < 60 ml/min/1.73 m(2)) has been increasing recently, it is unclear whether PCT is more accurate than C-reactive protein (CRP). We investigated the clinical value of CRP and PCT based on renal function.. From November 2008 to July 2011, a total of 493 patients who simultaneously underwent CRP and PCT tests were enrolled. The area under the receiver operating characteristic (ROC) curve and characteristics of both markers were analyzed according to infection severity and renal function.. In patients with impaired renal function, the area under the ROC curve was 0.876 for CRP and 0.876 for PCT. In patients with infection, CRP levels differed depending on whether the infection was localized, septic, or severely septic, whereas PCT levels were higher in patients with severe sepsis or septic shock. In patients without infection, CRP did not correlate with eGFR, while PCT was negatively correlated with eGFR.. This study demonstrates that CRP is accurate for predicting infection in patients with impaired renal function. The study suggests that in spite of its higher cost, PCT is not superior to CRP as an infection marker in terms of diagnostic value.

Use of an endotoxin adsorber in the treatment of severe abdominal sepsis.
    Acta anaesthesiologica Scandinavica, 2008, Volume: 52, Issue:7

    Methods for lipopolysaccharide (LPS) (endotoxin) reduction have been proposed as one way to improve the treatment of Gram-negative sepsis. Here we present a case with severe Gram-negative sepsis, treated with a novel device for LPS adsorption (Alteco LPS Adsorber, Alteco Medical AB, Lund, Sweden). After LPS adsorption, the level of LPS in the patient's bloodstream was almost eliminated: from 1.44 EU/ml before treatment to 0.03 EU/ml post treatment). The procalcitonin level and inflammatory cytokines were concurrently reduced. Also, an obvious improvement in the status of the patient's hemodynamics was seen. Forty-five days after treatment the patient is still alive. In conclusion, LPS adsorption may represent a significant improvement in the treatment of Gram-negative sepsis and further studies are planned.

The natural elimination rate of procalcitonin in patients with normal and impaired renal function.
    Intensive care medicine, 2000, Volume: 26 Suppl 2

    Procalcitonin (PCT) plasma concentrations and its kinetic can be used as a diagnostic tool in critically ill patients and patients with sepsis. Since renal dysfunction is a frequent complication in these patients, and PCT is a protein with a low molecular weight, we have measured the half-life time of PCT after peak concentrations in patients with normal and impaired renal function. We also have analyzed the influence of patients age and gender on PCT elimination kinetics.. Prospective clinical study. Renal dysfunction was assessed by plasma creatinine. The half-life time of PCT was evaluated 24 and 48 h after acute induction of PCT, when the focus of PCT induction has rapidly been eliminated.. Intensive care unit of our University hospital, a tertiary health care institution.. 69 patients were included into the study.. None.. The half-life-time of PCT was not significantly altered during renal dysfunction (26.1-33.1 h, 25-50 percentiles, creatinine clearance < 30 ml/min) when compared with normal renal function (22.3-28.9 h). It neither correlated with creatinine clearance (p=0.14), nor age (p=0.99) or gender (p=0.90, Pearson product-moment correlation).. The data of the present study demonstrate that assessment of PCT kinetic can also be used for diagnostic and prognostic reasons in patients with renal dysfunction. It may, however, exceed 24 h also in patients with normal renal function. As to the present knowledge, renal secretion does not contribute as a main pathway to PCT elimination.
