High serum concentrations of procalcitonin, a stable 116amino acid precursor molecule to the proteohormone calcitonin, have been reported in patients with severe systemic bacterial or fungal, but not viral, infections (1, 2 ). Serum procalcitonin concentrations correlated with the severity of bacterial infection and with the clinical course of the patients (3 ). In healthy volunteers, serum pro...
background :delay in diagnosis and treatment of acute appendicitis (aa) results in an increased rate of perforation, postoperative morbidity, mortality and hospital length of stay. several biochemical parameters including white blood cell (wbc) count, c-reactive protein (crp), interleukin-6 (il6) and procalcitonin (pct) have been used to further improve the clinical diagnosis of aa. the aim of ...
INTRODUCTION Whether the inflammatory biomarker procalcitonin provides prognostic information across clinical settings and different acute respiratory tract infections (ARIs) is poorly understood. In the present study, we investigated the prognostic value of admission procalcitonin levels to predict adverse clinical outcome in a large ARI population. METHODS We analysed data from 14 trials an...
Background :Delay in diagnosis and treatment of acute appendicitis (AA) results in an increased rate of perforation, postoperative morbidity, mortality and hospital length of stay. Several biochemical parameters including white blood cell (WBC) count, C-reactive protein (CRP), interleukin-6 (IL6) and Procalcitonin (PCT) have been used to further improve the clinical diagnosis of AA.

The level of procalcitonin is undetectable in healthy individuals and slightly increased in viral infections and noninfectious inflammatory responses. It has been described to be notably increased in bacterial, parasitic, or fungal infections. Procalcitonin has been reported to be a reliable marker for severe bacterial infections, although it has mainly been studied in specific entities or in s...
INTRODUCTION Procalcitonin is a reliable and specific marker of bacterial infections such as urinary tract infection. Some authors suggest measurement of serum procalcitonin as a predictor of vesicoureteral reflux (VUR). We investigated this association in children admitted because of acute pyelonephritis. MATERIALS AND METHODS Forty-eight children with the first febrile urinary tract infecti...
OBJECTIVE Procalcitonin may be associated with reduced antibiotic usage compared to usual care. However, individual randomized controlled trials testing this hypothesis were too small to rule out harm, and the full cost-benefit of this strategy has not been evaluated. The purpose of this analysis was to evaluate the effect of a procalcitonin-guided antibiotic strategy on clinical and economic o...
BACKGROUND/AIMS The relationships between serum procalcitonin, inflammatory bowel disease (IBD) and intestinal Behçet's disease (BD) have not been completely determined. We aimed to evaluate the usefulness of measuring serum procalcitonin levels to assess disease activity and infection stage in patients with IBD and intestinal BD. METHODS We retrospectively analyzed clinical data from 129 pat...
BACKGROUND Bacterial infections are frequent complications in patients with cirrhosis. Since they are associated with poor outcomes, antibiotics are frequently over-prescribed. Surrogate markers of bacterial infections, like procalcitonin, are needed to better discriminate between infected and not infected patients. AIMS To evaluated the diagnostic accuracy of an ultra-sensitive procalcitonin...
BACKGROUND Variability in the clinical presentation of infective endocarditis (IE) makes the diagnosis a clinical challenge. We hypothesized that serum procalcitonin, a marker of systemic bacterial infection, might be helpful in its diagnosis. METHODS AND RESULTS We conducted a prospective cohort study in 67 consecutive patients admitted to the hospital with the suspicion of IE or in whom the...
