OBJECTIVES: The aims of this study were to assess whether copeptin, pro-atrial natriuretic peptide, proadrenomedullin, and cortisol are associated with disease severity in patients with acute pancreatitis (AP) and to compare their ability in predicting organ failure or death. METHODS: From April 2011 to January 2015, 142 patients with AP were included in this prospective single-center study and observed for 4 days. Disease severity was rated by the Atlanta 1992 and 2012 criteria and organ failure by the modified Marshall score...

Nanomaterials themselves as redox probes and nanocatalysts have many advantages for electrochemical biosensors. However, most nanomaterials with excellent catalytic activity cannot be directly used as redox probe to construct electrochemical biosensor because the redox signal of these nanomaterials can only be obtained in strong acid or alkali solution at high positive or negative potential, which greatly limits their applications in biologic assay. In this study, Cu/Mn double-doped CeO2 nanocomposite (CuMn-CeO2) was synthesized to use as signal tags and signal amplifiers for the construction of electrochemical immunosensor for sensitive assay of procalcitonin (PCT)...

Timely recognition of systemic bacterial infections in pediatric care setting is the basis for effective treatment and control. This review provides an overview of procalcitonin (PCT) as an early marker for the detection of severe, invasive bacterial infection in children. Almost all articles on biochemical property and clinical studies in PubMed and Scopus databases regarding their use in pediatric infections and the use of PCT as a marker of bacterial infections were examined. Various methods and analyzers are currently available for the evaluation of PCT...

Background: Few studies compared the diagnostic value of procalcitonin with a combination of other tests including lactate and high-sensitivity C-reactive protein in the prediction of pathogenic bacteremia in emergency department adult patients. Methods: We performed a retrospective study assessing the differences in performances of procalcitonin at a cutoff of 0.5 ng/mL, lactate at a cutoff of 19.8 mg/dL, high-sensitivity C-reactive protein at a cutoff of 0.8 mg/dL and their combinations for predicting bacteremia in emergency department adult patients...

Ventilator-associated pneumonia (VAP) is a common and serious problem that develops after more than 48 h of mechanical ventilation. Improving the activity of immune system with vitamin D, and its consequent impact on prognostic biomarkers of VAP was studied in the current study. A randomized double blind placebo controlled clinical trial was designed. A total of 46 patients with VAP, who were suffering from vitamin D deficiency, were randomly allocated into the study groups of placebo (n=22) and treatment (n=24) The treatment group received 300,000 units of intramuscular vitamin D...

The aim of this study was to evaluate the procalcitonin (PCT) changes in two different high-dose colistin regimens in the treatment of multi-drug resistant MDR gram negative infections in ICU patients. This is a prospective study of adult ICU patients with bacteremia and ventilator associated pneumonia (VAP) caused by MDR gram negative pathogens. Patients were assigned to two colistin administration groups. Group A received 9 and group B received 3 million international units every 24 and 8 h respectively. Baseline characteristics and measurements of PCT concentrations at the start, the 3rd and the 5th day of the antibiotic therapy and their trends between the two groups were recorded and compared...

Multiple sclerosis (MS) is a common autoimmune and neurodegenerative disease of the central nervous system. Serum levels of melatonin decrease in MS patients who are also at risk of osteoporosis. Procalcitonin (proCT) has been reported as a biomarker of systemic inflammation and autoimmune disease, however, its changes in MS patients has not been well explored. This study investigated, using ELISA, the clinical correlation between serum melatonin and proCT in MS patients. We then assessed the effect of melatonin (10mg/kg) therapy on bone metabolism and osteoporosis in experimental autoimmune encephalomyelitis (EAE) model of MS and in MS patients...

INTRODUCTION: We hypothesized that aromatic microbial metabolites (AMM), such as phenyllactic (PhLA), p-hydroxyphenylacetic (p-HPhAA), and p-hydroxyphenyllactic (p-HPhLA) acids, contribute to the pathogenesis of septic shock. METHODS: Clinical and laboratory data of patients with community-acquired pneumonia were obtained on intensive care unit admission and the next day. Patients were divided into two groups based on septic shock presence or absence. The levels of AMM (PhLA, p-HPhAA, p-HPhLA, and their sum, ∑3AMM), catecholamine metabolites (3,4-dihydroxymandelic [DHMA], 3,4-dihydroxyphenylacetic [DOPAC], and homovanillic [HVA] acids), lactate, N-terminal pro-brain natriuretic peptide (NT-proBNP), inducible nitric oxide synthase (iNOS), and procalcitonin (PCT) were compared...

Introduction. Species of the genus Chryseobacterium are emerging healthcare-associated pathogens, often colonizing the hospital environment. There are no clear guidelines available for antimicrobial susceptibility of this organism. In this report we present the first case, to our knowledge, of simultaneous central-line-associated bloodstream infection (CLABSI) and ventilator-associated pneumonia (VAP) due to Chryseobacterium gleum from India. Case presentation. A 62 years old man with a history of a road traffic accident 1 month previously was referred to our center for further management...

Researchers estimate the incidence of early onset sepsis as 0.77-1/1,000 live births. It remains as one of the leading causes of neonatal deaths. Clinicians and researchers continue to search for biomarkers for specific neonatal disease processes. Clinicians frequently trend C-reactive protein levels during evaluation for neonatal sepsis. Recently, researchers have begun to explore procalcitonin as a potentially useful diagnostic marker for neonatal sepsis.

AIMS OF THE STUDY: While studies show that antibiotic treatment for uncomplicated diverticulitis seems to have no benefit, most experts advocate antimicrobial therapy for complicated diverticulitis. However, even for uncomplicated diverticulitis, most clinicians are very reluctant to withhold antibiotics. Biomarkers could help to guide antibiotic therapy as this approach has been shown to be effective for acute respiratory infections. In this diagnostic cohort study we evaluated whether procalcitonin could be a biomarker to distinguish complicated from uncomplicated cases of diverticulitis...

BACKGROUND: The aim of this study was to differentiate unspecific and self-limiting fever after bronchoscopy from fever due to infection by using serum procalcitonin, C-reactive protein and neutrophil count. Furthermore, frequency of fever after bronchoscopy and procedures as possible risk factors were evaluated. METHODS: Three hundred and fourteen consecutive patients were included. All bronchoscopies were performed using jet-ventilation and general anesthesia...

Previous studies have focused on relationship between plasma procalcitonin level and myocardial infarction risk, but this relationship in Asian elderly has not been investigated. The aim of this study was to reveal the association of peripheral procalcitonin concentration (both immediate and average levels) with myocardial infarction prognosis in Asian elderly. A total of 400 ST-elevation myocardial infarction patients, 400 unstable angina patients and 400 controls were included. Plasma levels of high-sensitivity C-reactive protein and procalcitonin were measured using commercially available kits...

BACKGROUND: Inflammatory biomarkers may aid to distinguish between systemic inflammatory response syndrome (SIRS) vs. sepsis. We tested the hypotheses that (1) presepsin, a novel biomarker, can distinguish between SIRS and sepsis, and (2) higher presepsin levels will be associated with increased severity of illness and (3) with 28-day mortality, outperforming traditional biomarkers. METHODS: Procalcitonin (PCT), C-reactive protein (CRP), presepsin, and lactate were analyzed in 60 consecutive patients (sepsis and SIRS, n=30 per group) on day 1 (D1) to D3 (onset sepsis, or after cardiac surgery)...
