An immediate PCT on patients presenting to ED with signs of sepsis in a non-specialised acute trust identifies those patients at an increased risk of deterioration and in hospital death. Procalcitonin is a peptide precursor of calcitonin and is part of the inflammatory cascade in sepsis. Procalcitonin levels tend to be elevated in bacterial infections whereas they are depressed in viral infections [ 4 ], and high PCT has been known to predict bacteremia [ 5 ]. However, ProCT could be an important and prognostic marker for sepsis [16, 17]. Following bacterial infection, the ProCT level rises in 6 to 12 hours and drops by 50% after 24 hours with the help Low PCT values (<0.25 µg/L) in patients with clinical signs of infection (CAP, UTI) indicate a low probability for blood culture proof of bacterial infection, whereas elevated PCT values (>0.25 µg/L) seem to correlate with the bacterial load and positive blood culture result.

High PCT concentrations are commonly found in bacterial infection, in contrast to much lower levels in viral infection.However, even though PCT is virtually undetectable (less than 0.1 ng/mL) in healthy individuals, elevated serum PCT concentrations are not always specific for sepsis. Moderate to high risk of sepsis: 2 µg/L and 10 µg/L. Severe sepsis: 10 µg/L or greater. The procalcitonin results can also be used to determine if an infection is likely to be caused by bacteria or a virus. If infection symptoms are severe but the procalcitonin level is low, the cause is more likely viral. Sepsis: PCT levels of >2.0 µg/L predicts sepsis and levels of >10 µg/L indicate likely septic shock. Sensitivity and specificity of PCT for the diagnosis of sepsis has varied based upon population and underlying diseases.

Measurement of procalcitonin levels for antibiotic decisions in patients with respiratory tract infections and sepsis appears to reduce antibiotic exposure without worsening the mortality rate.

Carey-Ann Burnham: In the setting of sepsis, there is a great need for a biomarker that is rapidly produced and easy to measure. A procalcitonin test measures the level of procalcitonin in your blood. A high level could be a sign of a serious bacterial infection, such as sepsis.

Our results showed that PCT levels on day 1 of diagnosis of sepsis differ significantly between surviving and nonsurviving patients of sepsis. The weighted mean

For patients admitted to the ICU with sepsis (see definition below), obtain a PCT level. In patients with an initial PCT <0.5 ng/mL, a repeat level should be drawn in 6-12 hours. In sepsis, procalcitonin serves as the surrogate for infection marker. Procalcitonin is actually the pro-hormone of calcitonin where it is normally synthesizing the C cells of thyroid gland.

Sepsis is defined as concern for infection + ≥2 SIRS criteria. PCT levels in sepsis are generally greater than 1-2 µg/L and often reach values between 10 and 100 µg/L, or considerably higher in individual cases, thus enabling the diagnostic differentiation between various clinical conditions and a severe bacterial infection (sepsis) (Fig. 1).

Serial Procalcitonin Predicts Mortality in Severe Sepsis Patients: Results From the Multicenter Procalcitonin MOnitoring SEpsis (MOSES) Study Results of this large, prospective multicenter U.S. study indicate that inability to decrease procalcitonin by more than 80% is a significant independent predictor of mortality and may aid in sepsis care.

-Levels above 2.0 ng/mL are highly suggestive of systemic bacterial infection/sepsis or severe localized bacterial infection, such as severe pneumonia, meningitis, or peritonitis. The procalcitonin levels in the sepsis-ICU-setting trials ranged from 4.5 to 12.0 ng/mL compared to 0.24–0.8 μg/L in the respiratory infection/pneumonia patients. Clearly, the septic patients in the ICU setting were more toxic, and this is reflected in the higher procalcitonin levels. Procalcitonin is a more reliable parameter than other markers in the diagnosis of bacterial sepsis, allowing better differentiation among sepsis-related fatalities.

ProCT levels below 0.5 ng/mL on the first day of ICU admission represent a low risk for progression to severe sepsis and/or septic shock. Reported sensitivity and specificity for the diagnosis of sepsis range from 60% to 100%, depending on underlying and coexisting diseases and the patient populations studied.

CONCLUSION: In the differentiation of sepsis and NI-SIRS, and evaluation of the prognosis of sepsis, combined measurements of procalcitonin and sTREM-1 levels are important. Studies have shown that, in patients with sepsis, higher procalcitonin levels are associated with a greater risk of progression to severe sepsis and septic shock, worsening the survival prognosis. Procalcitonin (PCT) increases after 2-3 hours after induction e.g. by endotoxin and may increase to levels up to several hundred nanogram per ml in severe sepsis and septic shock. After successful treatment intervention the procalcitonin value decreases, indicating a positive prognosis. In medicine, nothing is black and white, we all know this. Somehow, however, we have forgotten this regarding Procalcitonin which many clinicians use to rule In several studies Procalcitonin was found to be the best available marker for sepsis diagnosis in neonates Ref-1, 2, 3.

tonin, namely procalcitonin as a biomarker for sepsis. The serum PCT level rises rapidly than CRP levels and peaks within very short time; moreover, if the patient re-sponds appropriately to the treatment, the level of PCT returns to normal range faster than CRP which makes it a better biomarker for sepsis [20]. In general, PCT alone
