“…PCT is an established marker produced to some extent by leucocytes [2] used for specific and rapid diagnosis of neutropenic sepsis which is a medical emergency demanding active medical intervention [7,8]. The prognostic significance of PCT has already been established in studies with immunocompetent adult patients in ICU [9,10] and in children with febrile neutropenia [11,12].…”

Procalcitonin (PCT) is an innovative and highly specific marker for diagnosis of clinically relevant bacterial infection and sepsis. PCT supports early diagnosis and Clinical decision making. A retrospective study of two classical cases of neutropenic sepsis with elevated PCT levels in cardiac ICU was done. PCT was analyzed using Elecsys Brahms PCT kit. Serum PCT levels \0.5 ng/ml and ANC\1,000/mm 3 was taken as cutoff. The first patient had initial high levels of PCT 100 ng/ml, TLC 13,600/mm 3 and ANC 12,250/mm 3 . It was followed by drop with subsequent rise in PCT levels and drop in TLC 1,000/mm 3 and ANC 70/mm 3 . The second patient had normal PCT 0.116 ng/ml, TLC 5,600/mm 3 and ANC 4,420/mm 3 levels followed with sharp increase in all the values with subsequent drop in TLC 2,000/mm 3 and ANC 880 cells/mm 3 . Both the patients died of neutropenic sepsis with multiorgan failure. The case reports showed the correlation of PCT with TLC and ANC levels in predicting the mortality of patients with neutropenic sepsis in cardiac ICU.

“…1, P It is known that OKT3 induces a massive release of tumor necrosis factor alpha (TNF-a) [l]. Oberhoffer et al [3] found a pronounced stimulatory effect of TNF-a on expression of PCT mRNA. However, the rise of PCT levels observed under rejection therapy with OKT3 is not directly OKT3-mediated, but due to the intermediate step of TNF-a release.…”

AimTo investigate the clinical utility of interleukin‐6 (IL‐6), procalcitonin (PCT), and C‐reactive protein (CRP) as predictive markers in consideration of the time‐course changes in critically ill patients with organ dysfunction.MethodsSerum levels of IL‐6, PCT, CRP, and Sequential Organ Failure Assessment (SOFA) scores were measured sequentially in 92 patients during their initial 5 days following admission to the intensive care unit. Maximum values were analyzed. Patients were assigned to a low ( ≤ 8), intermediate ( > 8 and ≤ 16), or high ( > 16 and ≤ 24) SOFA score group.ResultsThere were significant differences in the maximum serum levels of IL‐6 and PCT among the three SOFA score groups (IL‐6, P < 0.0001; PCT, P = 0.0004). Specifically, comparisons between the groups revealed significant differences in IL‐6 levels (low versus intermediate, P = 0.0007; intermediate versus high, P = 0.0010). The probability of patients with the maximum value was greatest on day 1 (56.5%) for IL‐6, on day 1 (39.1%) or day 2 (38.0%) for PCT, on day 3 (39.1%) for CRP, and on day 1 (43.5%) for SOFA score. The median (interquartile range) peak day of IL‐6 was day 1 (1–2), which was significantly earlier than that of SOFA score at day 2 (1–3) (P = 0.018).ConclusionSerum levels of IL‐6 reflected the severity of organ dysfunction in critically ill patients most accurately compared to PCT and CRP. Interleukin‐6 elevated soonest from the insult and reached its peak earlier than SOFA score.
