- Abstract
Introduction and objective: Community-acquired sepsis is a life-threatening systemic reaction to infection starting 72 hours within hospital admittance. Data concerning kinetics of serum C-reactive protein (CRP) and procalcitonin (PCT) levels during disease progression are sparse. Our aim was to analyze kinetics of CRP and PCT among adults with community-acquired sepsis. Methods: We analyzed data of consecutive patients hospitalized with community-acquired sepsis at our centre during 2016. Sepsis was defined according to ACCP/SCCM criteria, community-acquisition was ascertained by a priori exclusion criteria. CRP and PCT values of days 1–14 were collected. Primary outcomes were in-hospital all-cause mortality, intensive care unit admission, secondary outcomes were septic source and the causative microorganism. Absolute (ΔabsCRP, ΔabsPCT) and relative (Δ%CRP, Δ%PCT) differences were calculated between values at the time of diagnosis and control values within 24 hours of empirical antimicrobial therapy initiation. Results: 193 patients were included. In-hospital all-cause mortality was 13.9%, intensive care unit admittance was 25.9%. Patients who died had significantly smaller median Δ%PCT decrements (–7.7 ± 127.9% vs. –45.7 ± 88.8%, p = 0.01), compared to survivors. During hospital stay, daily absolute values of PCT on days 2–14, while those of CRP on days 5–14 were significantly higher among patients who died. Patients admitted to the intensive care unit also had smaller median Δ%PCT decrements (–19.6 ± 72.5% vs. –49.8 ± 100.8%, p = 0.01), compared to non-admitted patients. Calculated parameters did not show significant correlations with septic focus or causative microorganisms. Discussion, conclusion: Our findings suggest that specific fluctuations of CRP and PCT are observable, and Δ%PCT might be a favourable parameter for outcome prediction among adults with community-acquired sepsis.
