Article Abstract

Unlabelled: Sepsis is the major cause of morbidity and mortality in children, especially in immunocompromised patients, and a rapid identification of causative pathogen is strongly related with a better outcome. This prospective study analyzes the role of a multiplex real-time polymerase chain reaction in sepsis' etiological diagnosis. Magicplex(TM) Sepsis Real-Time tests were performed in tertiary Regina Margherita Children's Hospital (Turin, Italy), and the medical records of children who underwent a Magicplex test were prospectively evaluated. Results of the Magicplex test were compared with those of blood culture collected at a close time point. One hundred fifty Magicplex tests were collected from 89 patients (54 males and 35 females, age interquartile range: 2.6-12.1 years). Etiological definition was achieved in 60 bloodstream infection cases (40 %). In 32 episodes, Magicplex test alone gave a positive result, and blood culture alone permitted the etiological diagnosis in 5 septic episodes. Magicplex test allowed a 143 % increase in the diagnostic value of blood cultures.

Conclusion: These results suggest that molecular biology can be useful for rapid pathogen's identification also in children.

What Is Known: • Sepsis represents a major cause of morbidity and mortality in children. • Sepsis outcome is strongly related to rapid microbiological identification and prompt initiation of an appropriate chemotherapy. What is New: • This manuscript is the first that describes the use of Magicplex (TM) Sepsis Real-Time test in children. • The results suggest that molecular biology can be useful for rapid pathogen's identification also in children.

Background: Timely management of sepsis with early targeted antimicrobial therapy improves patient outcomes. Rapid molecular assays (RMAs) have emerged, enabling the detection of bloodstream infection (BSI) with a shorter turnaround time than blood cultures (BCs). The accuracy of several RMAs has not been comprehensively reviewed.

Background: Blood culture (BC) is the established gold standard for microbiological diagnosis of bloodstream infection (BSI); however, its sensitivity is poor.

Objectives: The primary objective was to determine the sensitivity and specificity of the Magicplex Sepsis Real-time Test, a multiplex polymerase chain reaction test (mPCR), and BC to detect BSIs. Secondary outcomes included determining the prevalence of BSIs.

Background: Sepsis and bloodstream infection are associated with significant morbidity and mortality, and early effective antimicrobial therapy has been demonstrated to improve patient outcomes. Traditional culture-based methods, however, have several limitations that hamper a prompt diagnosis in bloodstream infection, including long turnaround times and limited sensitivity. In recent years, advances have been made in the development of several technologies that allow the identification of pathogens and their resistance markers directly from whole blood, possibly representing promising alternatives to conventional culture-based methods.

Sepsis is a serious health condition worldwide, affecting more than 30 million people globally each year. Blood culture (BC) is generally used to diagnose sepsis because of the low quantity of microbes occurring in the blood during such infections. However, ~50% of bloodstream infections (BSI) give negative BC, this figure being higher for sepsis, which delays the start of appropriate antimicrobial therapy.

Septicemia remains a major cause of hospital mortality. Blood culture remains the best approach to identify the etiological microorganisms when a bloodstream infection is suspected but it takes long time because it relies on bacterial or fungal growth. The introduction in clinical microbiology laboratories of the matrix-assisted laser desorption ionization time-of-flight mass spectrometry technology, DNA hybridization, microarrays or rapid PCR-based test significantly reduce the time to results.
