BACKGROUND: Postoperative pneumonia is frequent after cardiac surgery and is associated with increased morbidity and mortality. We tested the hypothesis that endocan is an early biomarker for the detection of pneumonia after cardiac surgery. METHODS: Between January and May 2016, 155 patients scheduled to undergo elective cardiac surgery with cardiopulmonary bypass were prospectively included in the study. Serum level of endocan was measured at five timepoints (preoperative, and at 6, 24, 48, and 72 hours after the end of surgery)...

Due to overlap of clinical findings and low sensitivity of bacterial diagnostic tests, differentiation between bacterial and viral respiratory tract infections remains challenging, ultimately leading to antibiotic overuse in this population of patients. Addition of procalcitonin, a blood biomarker expressed by epithelial cells in response to bacterial infections, to the clinical assessment leads to a reduction in inappropriate antibiotic initiation. Procalcitonin also provides prognostic information about the resolution of illness, and significant decreases over time are a strong signal for the discontinuation of antibiotics...

Background/Aims: Procalcitonin (PCT) may prove to be a useful marker to exclude or predict bloodstream infection (BSI). However, the ability of PCT levels to differentiate BSI from non-BSI episodes has not been evaluated in nosocomial BSI. Methods: We retrospectively reviewed the medical records of patients ≥ 18 years of age with suspected BSI that developed more than 48 hours after admission. Results: Of the 785 included patients, 105 (13...

The management of children with fever without apparent sources (FWAS) is difficult. This study aimed to evaluate the diagnostic accuracy of procalcitonin (PCT) in detecting serious or invasive bacterial infection (SBI or IBI) in children with FWAS. Areas covered: A systematic review of literature from 2007 to 2017 was performed on Medline. Twelve studies were included, involving 7,260 children with FWAS and analyzing the diagnostic performance of PCT. Four meta-analyses were performed to calculate pooled sensitivity, specificity, diagnostic odds ratio, and summary receiver operating characteristic curve for PCT in detecting SBI and IBI, at two different thresholds...

Infants aged 90 days or younger with fever are frequently evaluated in the pediatric emergency department. Physical examination findings and individual laboratory investigations are not reliable to differentiate benign viral infections from serious bacterial infections in febrile infants. Clinical prediction models were developed more than 25 years ago and have high sensitivity but relatively low specificity to identify bacterial infections in febrile infants. Newer laboratory investigations such as C-reactive protein and procalcitonin have favorable test characteristics compared with traditional laboratory studies such as a white blood cell count...

BACKGROUND: Acute respiratory infections (ARIs) comprise of a large and heterogeneous group of infections including bacterial, viral, and other aetiologies. In recent years, procalcitonin (PCT), a blood marker for bacterial infections, has emerged as a promising tool to improve decisions about antibiotic therapy (PCT-guided antibiotic therapy). Several randomised controlled trials (RCTs) have demonstrated the feasibility of using procalcitonin for starting and stopping antibiotics in different patient populations with ARIs and different settings ranging from primary care settings to emergency departments, hospital wards, and intensive care units...

C-reactive protein (CRP) and myxovirus resistance protein A (MxA) are associated with bacterial and viral infections, respectively. We conducted a prospective, multicenter, cross-sectional study of adults and children with febrile upper respiratory tract infections (URIs) to evaluate the diagnostic accuracy of a rapid CRP/MxA immunoassay to identify clinically significant bacterial infection with host response and acute pathogenic viral infection. The reference standard for classifying URI etiology was an algorithm that included throat bacterial culture, upper respiratory PCR for viral and atypical pathogens, procalcitonin, white blood cell count, and bandemia...

Early diagnosis of urinary tract infection (UTI) is challenging in infants due to unspecific symptoms, difficulty in urine collection and possible contamination. The aim of this study was to assesses the usefulness of serum and urine neutrophil gelatinase-associated lipocalin (sNGAL and uNGAL, respectively) in the diagnosis of febrile and non-febrile UTI in infants. This prospective observational study enrolled 66 infants with the first episode of UTI and 18 healthy controls. At the time of enrollment, sNGAL, uNGAL, urinalysis, urine culture, white blood cell count (WBC), C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), procalcitonin (PCT), and serum creatinine (sCr) were assessed...

BACKGROUND: Inflammation plays an important role in obstructive sleep apnea syndrome (OSAS). The objective of this study was to investigate the relationship of serum C-reactive protein(CRP), pentraxin-3(PTX-3), procalcitonin(ProCT), interleukin-33(IL-33) and its soluble receptor ST2 (sST2) with the syndrome severity and to show theirs importance as biomarkers. METHODS: This study comprises a total of 84 identical (sex and age wise) cases. Full-night polysomnography was performed in each patient...

We report the case of a 54-year-old man with metastatic pulmonary neuroendocrine tumor associated with major procalcitonin (PCT) elevation without sepsis. Three lines of antibiotic therapies were successively introduced but had no positive effect on PCT kinetic and disease progression. Under palliative care, increasing of PCT level was constant during the hospitalization, along with major asthenia and pain and metastatic progression. PCT is an excellent biological marker of bacterial infection, both sensitive and specific...

Infections and infectious complications are the major cause of morbidity and mortality in febrile neutropenic patients after autologous stem cell transplantation. Laboratory biomarkers are helpful for early identification of critically ill patients and optimal therapy management. Several studies in adult non-neutropenic patients proposed sTREM-1 as a superior biomarker for identification of septic patients as well as a predictor for survival in these patients compared with procalcitonin (PCT), C-reactive protein (CRP), or interleukin-8 (IL-8)...

BACKGROUND: Reliably distinguishing bacterial from viral infections is often challenging, leading to antibiotic misuse. A novel assay that integrates measurements of blood-borne host-proteins (tumor necrosis factor-related apoptosis-inducing ligand, interferon γ-induced protein-10, and C-reactive protein [CRP]) was developed to assist in differentiation between bacterial and viral disease. METHODS: We performed double-blind, multicenter assay evaluation using serum remnants collected at 5 pediatric emergency departments and 2 wards from children ≥3 months to ≤18 years without (n = 68) and with (n = 529) suspicion of acute infection...

BACKGROUND: It is vital to recognize the cause of an infection to enable earlier treatment. Studies have shown that procalcitonin (PCT) and C-reactive protein (CRP) have very high sensitivity and specificity for diagnosing serious bacterial infections (SBIs), with PCT performing better than CRP. METHODS: Multiple databases were searched for relevant studies, and full-text articles involving diagnosis with PCT and CRP were reviewed. All meta-analyses were conducted with Review Manager 5...
