Procalcitonin has been proposed as a specific biomarker of bacterial infections and has been related to the severity of sepsis. The prognostic ability of the initial concentrations of procalcitonin in sepsis is controversial. Some studies find higher initial concentrations in non-survivors but others find no differences. Prognostic assessment based on follow-up of procalcitonin levels may be be...
Abstract Background: Respiratory distress syndrome is one of most common problems in neonatal medicine. Procalcitonin is a protein, which increases in acute bacterial infection, but this issue is a controversy in hyaline membrane disease. The purpose of this study was to compare serum procalcitonin in hyaline membrane disease, sepsis and pneumonia in Khatam al-Anbiya hospital of Tehran. Materia...
BACKGROUND Procalcitonin has been advocated as a marker of bacterial infection, so this study was carried out to determine the usefulness of serum procalcitonin in the early diagnosis of urosepsis. METHODS The subjects were 37 febrile patients with urinary tract infection in whom we examined the serum procalcitonin concentration at the start of treatment. RESULTS Thirty patients had acute p...
OBJECTIVE To systematically review evidence of the accuracy of the procalcitonin test for diagnosis of bacterial infection in patients with autoimmune disease. METHODS The major databases Medline, EMBase, and the Cochrane Library were searched for studies published between January 1966 and October 2011 that evaluated procalcitonin, alone or in comparison with other laboratory markers such as ...
BACKGROUND Community-acquired pneumonia (CAP) is one of the leading causes of death among the elderly. Several studies have reported the clinical usefulness of serum procalcitonin, a biomarker of bacterial infection. However, the association between the levels of procalcitonin and the severity in the elderly with CAP has not yet been reported. The aim of this study was to evaluate usefulness of...
Background. Procalcitonin has emerged as a promising biomarker of bacterial infection. Published literature demonstrates that use of procalcitonin testing and an associated treatment pathway reduces duration of antibiotic therapy without impacting mortality. Procalcitonin testing, however, is an additional expenditure which may or may not be offset by treatment-related financial gains. The cost...
Procalcitonin usefulness for the initiation of antibiotic treatment in intensive care unit patients.
OBJECTIVES To test the usefulness of procalcitonin serum level for the reduction of antibiotic consumption in intensive care unit patients. DESIGN Single-center, prospective, randomized controlled study. SETTING Five intensive care units from a tertiary teaching hospital. PATIENTS All consecutive adult patients hospitalized for >48 hrs in the intensive care unit during a 9-month period. ...
The impact of tracheotomy on levels of procalcitonin in patients without sepsis: a prospective study
OBJECTIVE Procalcitonin is a reliable biomarker of infection and sepsis. We aimed to determine whether tracheotomy influences the procalcitonin concentrations in patients without sepsis and assess whether operative duration and procedure affect the peak procalcitonin level. METHODS A total of 38 non-septic patients who required a tracheotomy underwent either a percutaneous dilatational trache...
BACKGROUND AND PURPOSE We investigated the potential role of serum procalcitonin in differentiating tuberculosis meningitis from bacterial and viral meningitis, and in predicting the prognosis of tuberculosis meningitis. METHODS This was a retrospective study of 26 patients with tuberculosis meningitis. In addition, 70 patients with bacterial meningitis and 49 patients with viral meningitis w...
348 Iranian Journal of Kidney Diseases | Volume 8 | Number 4 | July 2014 stress, although there is no bacterial infection. In these situations, after the elevation of procalcitonin values, a rapid decline is observed in the follow-up measurements. 3 On the other hand, procalcitonin can have false negative or lower values in early course and localized site of an infection. 3 In this context, rep...
