Background: Randomized trials support use of procalcitonin-based algorithms to decrease duration of antibiotics for critically ill patients with sepsis. However, current utilization of procalcitonin and associated outcomes in "real world" clinical settings is unclear. We sought to determine procalcitonin utilization in critically ill patients with sepsis in the United States and to examine associations between procalcitonin use and clinical outcomes. Methods: Retrospective cohort study of approximately 20% of patients hospitalized in US Intensive Care Units with sepsis...

A nanochannel-based electrochemical biosensor has been demonstrated for rapid and multiplexed detection of a panel of three biomarkers associated with rapid detection of sepsis. The label-free biosensor detected procalcitonin (PCT), lipoteichoic acid (LTA), and lipopolysaccharide (LPS) from human whole blood. The biosensor comprises a nanoporous nylon membrane integrated onto a microelectrode sensor platform for nanoconfinement effects. Charge perturbations due to biomarker binding are recorded as impedance changes using electrochemical impedance spectroscopy...

Procalcitonin (PCT) has been reported as a sensitive marker for neonatal bacterial infections. Recently, small numbers of studies reported usefulness of PCT/C-reactive protein (CRP) ratio in detection of infectious conditions in adults. Thus, we conducted this study to evaluate PCT/CRP ratio in late onset neonatal sepsis. Serum PCT and CRP was measured in blood samples from 7-60 days after birth in 106 of neonates with late onset sepsis and 212 of controls who were matched with gestational age, postnatal age, birth weight and gender...

BACKGROUND: Biomarker could be objective and reliable tools to predict mortality in sepsis. We explored the prognostic utilities of emerging biomarkers in septic patients and questioned whether adding biomarkers to the clinical variables would improve the prediction of mortality in sepsis. METHODS: This retrospective study included 157 septic patients (112 patients with sepsis; 45 patients with septic shock). Procalcitonin (PCT), presepsin, galectin-3, and soluble suppression of tumorigenicity 2 (sST2) concentrations were analyzed in relation to the 30-day all-cause mortality...

INTRODUCTION: Early diagnosis and immediate therapeutic intervention, including appropriate antibiotic therapy and goal-directed resuscitation, are necessary to reduce mortality in patients with sepsis. However, a single clinical or biological marker indicative of sepsis has not been adopted unanimously. Although procalcitonin and presepsin are promising biomarkers that can effectively differentiate between sepsis/infection and systemic inflammatory response syndrome of non-infectious origin, little is known about which marker is superior...

Procalcitonin (PCT) is a current, frequently-used marker for severe bacterial infection. The aim of this study was to develop a cost-effective detection kit for rapid quantitative and on-site detection of PCT. To develop the new PCT quantitative detecting kit, a double-antibody sandwich immunofluorescent assay was employed based on time-resolved immunofluorescent assay (TRFIA) combined with lateral flow immunoassay (LFIA). The performance of the new developed kit was evaluated in the aspects of linearity, precision, accuracy, and specificity...

OBJECTIVES: Higher coronary atherosclerotic burden has been associated with increased cardiovascular events including mortality. The SYNTAX score (SXs) reflects coronary atherosclerotic burden. Given the body of evidence implicating inflammation in atherosclerotic process, we hypothesized that procalcitonin (PCT) as an inflammatory marker may be related to coronary atherosclerotic burden. Thus, we aimed to investigate the relationship between serum PCT levels and SXs in patients with stable CAD...

Mid-regional pro-adrenomedullin (MR-proADM) has been used as a marker of sepsis, but its dynamics and role in a burn injury setting has not been tested. In a prospective observational study, we included 42 consecutive patients with >15% TBSA. Daily blood specimens collected during the initial 20 days of treatment were submitted for laboratory analysis of MR-proADM and procalcitonin (PCT) via immunoluminometric sandwich assay (Kryptor, BRAHMS, Berlin, Germany). In patients with an absence of sepsis, an initial increase in MR-proADM and PCT levels was noted post burn injury, peaking on the second day post admission and thereafter demonstrated a continued decline in MR-proADM and PCT levels...

Various procalcitonin ranges have been established to guide antimicrobial therapy; however, there are no data that establish whether the initial procalcitonin value will determine the likelihood of a positive culture result. This study aims to establish if the initial procalcitonin value on clinical presentation can provide positive predictive value of any positive culture result.This was a retrospective study of 813 medical intensive care unit patients. Data points collected included patient demographics, procalcitonin assays, source of infection, culture results, and length of stay...

Accurate diagnosis of bacterial meningitis (BM) relies on cerebrospinal fluid (CSF) Gram stain and bacterial culture, which often present high false-negative rates because of the antibiotic abuse. Thus a novel and reliable diagnostic biomarker is highly required. Procalcitonin (PCT) is well demonstrated to be specifically produced from peripheral tissues by bacterial infection, which makes it a potential candidate. Here, we performed a prospective clinical study comprising a total of 143 patients to investigate the diagnostic value of CSF PCT, serum PCT and other conventional biomarkers for BM...

BACKGROUND: Cell free DNA (cfDNA) was recently suggested as a new marker of sepsis and poor outcome in ICU patients. Procalcitonin has also been the focus of attention as an early marker for systemic inflammation and sepsis. METHODS: cfDNA, procalcitonin (PCT), C-reactive protein (CRP), and lactate levels were measured in 30 ICU patients with multiple trauma or after major surgery on the first day of admission and on 5th and 7th days for PCT, CRP, and lactate. cfDNA was measured by real-time PCR, PCT by ELISA, CRP immunoturbidimetrically, and lactate spectrophotometrically...

BACKGROUND: Bacterial pleural infection requires prompt identification to enable appropriate investigation and treatment. In contrast to commonly used biomarkers such as C-reactive protein (CRP) and white cell count (WCC), which can be raised due to non-infective inflammatory processes, procalcitonin (PCT) has been proposed as a specific biomarker of bacterial infection. The utility of PCT in this role is yet to be validated in a large prospective trial. This study aimed to identify whether serum PCT is superior to CRP and WCC in establishing the diagnosis of bacterial pleural infection...

INTRODUCTION: Infections represent a major complication of hematological malignancies. C-reactive protein (CRP) and procalcitonin (PCT) have been used as diagnostic biomarkers of infections, but do not produce definitive findings. Recently, a new biomarker, presepsin, has been used as a diagnostic tool for detecting infections in the fields of emergency and neonatal medicine. However, the usefulness of presepsin for identifying infections in patients with hematological malignancies, including those who develop febrile neutropenia, remains unclear...
