BACKGROUND: Severe hand, foot, and mouth disease (HFMD) is sometimes associated with serious complications such as acute heart failure that can cause substantial child mortality. N-terminal pro-brain natriuretic peptide (NT-proBNP) is a sensitive and specific biomarker of congestive heart failure. The aim of this study was to use plasma NT-proBNP levels to establish the severity of childhood HFMD. METHODS: A retrospective study was performed in 128 Chinese patients with severe HFMD and 88 patients with mild HFMD treated between January 2014 and October 2015...

BACKGROUND: The detection of infectious bacteria in blood culture samples is important for diagnosis and treatment, but this requires 1-2 days at least, and is not adequate as a rapid test. Therefore, we have investigated the diagnostic ability and the optimal cutoff value of procalcitonin (PCT) and C-reactive protein (CRP) for predicting the bacteremias using receiver operating characteristic (ROC) curves and relative cumulative frequency distribution (RCD) curves. METHODS: A case-control study was performed in inpatients (852 subjects: 426 positive cultures and 426 negative cultures) from January 1 to December 31, 2014...

A surface plasmon resonance (SPR) biosensor has been developed for rapid immunoassay of procalcitonin (PCT) with high detection sensitivity and reproducibility. The 1-ethyl-3-(3-dimethylaminopropyl)-carbodiimide hydrochloride (EDC)-activated protein A (PrA), diluted in 1% (v/v) 3-aminopropyltriethoxysilane (APTES) was dispensed on a KOH-treated Au-coated SPR chip, resulting in the covalent binding of PrA in 30 min. This "single-step" PrA immobilization strategy led to the oriented binding of the anti-PCT antibody (Ab) on a PrA-functionalized gold (Au) chip...

The research was performed to explore the diagnosis value of dynamic serum calprotectin (SC) expression for sepsis in postoperative intensive care unit patients. One hundred sixty-three patients who met the inclusion criteria served as the study group. All cases in the study group were further divided into the sepsis subgroup (51 cases) and the nonsepsis subgroup (112 cases). Fifty healthy volunteers served as the control group. The levels of SC and other laboratory indexes including complete blood counts, leukocytes, the immature-to-total-neutrophil ratio, procalcitonin (PCT), C-reactive protein, and blood lactate were detected, cytokines [interleukin (IL)-2, IL-6, and interferon-γ] released by neutrophils were also determined...

Differentiating between sepsis and non-infectious systemic inflammatory response syndrome (SIRS) poses a great challenge. Several potential bloodstream biomarkers including Interleukin 6 (IL-6) have been investigated for their ability to diagnose sepsis. We conducted the present meta-analysis to evaluate the diagnostic quality of IL-6 in differentiating sepsis from non-infectious SIRS in adults. We also compared its accuracy with procalcitonin (PCT) and C-reactive protein (CRP). PubMed and EMBASE were systematically searched for studies published up to January 18, 2016...

We aimed to investigate the clinical importance of serum procalcitonin (PCT) levels in the diagnosis of tubo-ovarian abscess (TOA). Patients diagnosed with pelvic inflammatory disease (PID; n = 36) and patients diagnosed with TOA (n = 42) were included in the study. Sociodemographic characteristics, laboratory and clinical parameters were compared between the 2 groups. Mean PCT level was higher in the TOA group (p = 0.004). Mean length of stay in hospital was longer in patients with TOA (p < 0.001). White blood cell count, neutrophil count, percentage of neutrophils and C-reactive protein levels were higher than normal limits in all patients; however, no differences in these parameters were observed between the groups...

Soluble suppression of tumorigenicity 2 (sST2) has emerged as a biomarker of cardiac stretch or remodeling, and has demonstrated a role in acutely decompensated heart failure. However, its role in sepsis-induced cardiac dysfunction is still unknown. We explored whether sST2 serum concentration reflects either systolic or diastolic dysfunction as measured by Doppler echocardiography. In a total of 127 patients with sepsis, correlations between sST2 and blood pressure, left ventricular (LV) ejection fraction, LV diastolic filling (ratio of early transmitral flow velocity to early diastolic mitral annulus velocity), and resting pulmonary arterial pressure were evaluated...

PURPOSE: Infectious diseases are a major cause of morbidity and mortality in cancer patients. Tumor-induced inflammatory responses may increase the value of classical inflammatory markers in blood, so these markers may not be as useful in cancer patients as in non-cancer patients. Serum procalcitonin (PCT) is a sensitive and specific biomarker for severe infection, and has been shown to be unaffected by tumor-induced inflammatory response. In this study we aimed to evaluate the possible role of PCT in mortality in cancer patients with infection...
