Procalcitonin (PCT) is a peptide precursor of the hormone calcitonin, the latter being involved with calcium homeostasis. It arises once preprocalcitonin is cleaved by endopeptidase . [ 1 ] It was first identified by Leonard J. Deftos and Bernard A. Roos in the 1970s. [ 2 ]
A systematic review of 32 randomised controlled trials with 6,078 participants with acute respiratory infections compared procalcitonin (a blood marker for bacterial infections) to guide the initiation and duration of antibiotic treatment, against no use of procalcitonin. Among 3,336 people receiving procalcitonin-guided antibiotic therapy ...
She is a member of the National Institute for Health and Care Excellence (NICE) sepsis development group. [6] As part of this work, Carrol has studied the use of antibiotics in treating sepsis. [7] She is interested in whether Procalcitonin (PCT) could be used to improve the assessment and treatment of sepsis.
A large international collaboration entitled the "Surviving Sepsis Campaign" was established in 2002 [134] to educate people about sepsis and to improve outcomes with sepsis. The Campaign has published an evidence-based review of management strategies for severe sepsis, with the aim to publish a complete set of guidelines in subsequent years ...
The use of eosinopenia as a diagnostic tool in sepsis is debatable. [10] Although there is a high incidence of eosinopenia in sepsis, it is not more effective as a biomarker than more commonly utilized indicators of sepsis, such as procalcitonin (PCT) and C-reactive protein (CRP). [10]
Bacteremia can have several important health consequences. Immune responses to the bacteria can cause sepsis and septic shock, which, particularly if severe sepsis and then septic shock occurs, have high mortality rates, especially if not treated quickly (though, if treated early, currently mild sepsis can usually be dealt with successfully). [6]
The SOFA scoring system is useful in predicting the clinical outcomes of critically ill patients. [8] According to an observational study at an Intensive Care Unit (ICU) in Belgium, the mortality rate is at least 50% when the score is increased, regardless of initial score, in the first 96 hours of admission, 27% to 35% if the score remains unchanged, and less than 27% if the score is reduced.

Evidence of COVID-19 (RT-PCR, antigen test or serology positive), or likely contact with patients with COVID-19 (Note: Consider this syndrome in children with ...
