Clinical symptoms of septicemia, clinical outcome, and laboratory parameters of septicemia (C-reactive protein) were studied retrospectively in 66 patients with CONS septicemia.
Circulating concentrations of the sensitive inflammatory marker C-reactive protein (CRP) predict future cardiovascular events, and CRP is elevated during sepsis and inflammation, when vascular reactivity may be modulated.
Therefore, the diagnosis of sepsis is often based on the development of clinical signs, in combination with laboratory tests such as a rise in C-reactive protein (CRP).
It more closely matches the criteria for usefulness than other candidate biomarkers such as C-reactive protein, which is rather a nonspecific marker of acute phase inflammation, and proinflammatory cytokines such as plasma IL-6 levels that are highly variable, cumbersome to measure, and lack specificity for systemic infection.
To clarify the effect of these SNPs to CRP response in systemic infections, we compared genetic and clinical data on patients with Staphylococcus aureus bacteremia (SAB).
Receiver operating characteristic curves showed that miR-15a had the highest area under the curve of 0.858 [95% confidence interval (CI) 0.800-0.916] for the diagnosis of sepsis compared with C reactive protein and procalcitonin with areas under the curve of 0.572 (95% CI 0.479-0.665; p=0.198) and 0.605 (95% CI 0.443-0.767; p=0.168), respectively.
178 biomarkers are described in the literature--ranging from specimen cultures, which lack sensitivity and specificity for early diagnosis of sepsis, to biomarkers such as C-reactive protein, procalcitonin, and genetic biomarkers, which have their own limitations.
The area under the ROC curve for MMP-8 in the diagnosis of sepsis was 0.87 (95% CI 0.82-0.92), and that of CRP was 0.98 (0.94-0.998), whereas the area of MMP-9 in the detection of non-septic state was 0.73 (0.65-0.80), p < 0.0001 for all curves.
It was found that a history of relapse, a refractory state of underlying disease, and high C-reactive protein concentrations at the beginning of fever were significant risk factors for mortality after developing sepsis.
The area under ROC curve showed that the clinical accuracy of microRNA-25 for sepsis diagnosis was better than CRP and PCT (AUG=0.806, 0.676 and 0.726, P<0.05).The decrease in level of microRNA-25 was correlated with the severity of sepsis, SOFA score, CRP and PCT level, meanwhile, microRNA-25 level can be used for predicting the prognosis of patients, the patients with microRNA-25 level ≤0.492 had a lower 28 d survival rate.
Genetic analysis found that individuals with the polymorphism of the FcγRIIa receptor that binds CRP poorly were also more likely to have decreased monocyte human leukocyte antigen DR and posttraumatic sepsis.
The association of theses SNPs with the following parameters was evaluated: (1) the presence of sepsis; (2) severity and clinical outcomes; (3) APACHE II and SOFA scores; and (4) procalcitonin, C-reactive protein, tumor necrosis factor, lymphotoxin alpha, interleukin 1 beta and interleukin 10 plasma concentrations.
We concluded that CRP dosage at hospital admission is helpful to detect acute infection, and particularly sepsis, in geriatric patients, and that CRP elevation may provide valuable short-term prognostic information.
Six hours of polymicrobial sepsis elicited by cecal ligation and puncture (CLP) elevated serum C-reactive protein (CRP) (a bacteremia and sepsis marker) concentration in anesthetized and mechanically ventilated neonatal pigs.
In univariate analyses, higher age (p = 0.04), higher levels of C-reactive protein (p < 0.001), etiology of PRES (sepsis and chemotherapy; p = 0.02), altered coagulation (p = 0.002), altered mental state at onset (p = 0.03), and subarachnoid hemorrhage (SAH; p = 0.01) were related to in-hospital death.
The rs1764390 G allele is associated with increased susceptibility to sepsis, which may be involved in the process of sepsis via mediating the plasma levels of NO, IL-6 and CRP.
IDO and kynurenine showed a strong positive correlation with markers of infection (procalcitonin) and inflammation (C-reactive protein) as well as sepsis and CAP severity scores.
In conclusion, 1,25(OH)D but not 25(OH)D showed a minor discriminatory value for the prediction of bacteraemia that was inferior to CRP and PCT but both failed to predict sepsis and mortality in a prospective cohort of SIRS patients.
In a logistic regression analysis including TRX, C-reactive protein, injury severity, massive transfusion, and admission blood pressure, TRX was the only variable independently associated with post-injury sepsis.
In these patients, median (interquartile range) LBP (41.8 [41.1] µg/dL vs. 26.2 [25] µg/dL), CRP (240 [205] mg/L vs. 160 [148] mg/dL) and PCT (5.19 [13.68] µg/L vs. 0.39 [1.09] µg/L) were significantly higher than in patients classified as not having sepsis ( P < 0.001 for all three biomarkers).
