Infected mice injected with wild-type or mutant CRP had reduced bacteremia, resulting in lower mortality and increased longevity compared with mice that did not receive CRP.
To discover if variation in the CRP gene is associated with clinical outcome of bacteraemia, we investigated 147 microbiologically verified bacteraemia patients (mean age 59 y, range 19-93 y) and determined whether CRP -717A>G, +1059G>C or +1444C>T single nucleotide polymorphisms (SNPs) were associated with clinical outcome of bacteraemia and/or CRP concentration caused by Staphylococcus aureus, Streptococcus pneumoniae, beta-haemolytic streptococci or Escherichia coli.
We conclude that the CRP-mediated decrease in bacteremia and the resulting protection of mice are independent of an interaction between CRP and the pathogen and therefore are independent of the ability of CRP to activate mouse complement.
Performance of presepsin to predict bacteraemia [AUC=0.63, 95%CI: 0.55-0.72] was similar to CRP (AUC=0.64, p=0.87) and less accurate than PCT (AUC=0.78, p<0.001).
Multivariate analysis identified CRP values and low blood pressure as independent predictors of bacteremia: CRP (odds ratio [OR] 1.11; 95% confidence interval [CI] 1.04-1.19, P = 0.003) and low blood pressure (OR 6.03; 95% CI 1.06-34.25, P = 0.04).
The presence of solid tumor, elevated neutrophil count, elevated C reactive protein, and pyuria are independent risk factors that could be useful in anticipating the development of bacteremia in patients with UTI seen in the ED.
Median CRP and PCT were highly and significantly increased during sepsis/SIRS and bacteremia (17.24 mg/dl ; 6.30 ng/ml; p < 0.0001 vs. prior values), graft rejection (14.73 mg/dl ; 3.20 ng/ml; p < 0.0001), and liver GvHD (6.88 mg/dl ; 2.29 ng/ml; p < 0.01).
The CRP-value at the time of implantation of a permanent hemodialysis catheter is not associated with the development of early catheter related infections, but an individual history of catheter-related infection, MRSA-carriage and bacteremia or bacteriuria in the period of 3 months prior to catheter implantation are significant risk factors.
We aimed to evaluate the utility of procalcitonin (PCT), presepsin (PS), C-reactive protein (CRP) and interleukin-8 (IL-8) as biomarkers of bacteraemia in adult FN patients with haematological malignancies.
C-reactive protein (CRP), interleukin (IL)-6, IL-8 and procalcitonin (PCT) consistently predict bacteraemia and severe sepsis; other outcomes have highly heterogeneous results.
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.
Area under receiving operating curve of C-reactive protein, lactate and procalcitonin for predicting bacteremia and 28-day mortality were also evaluated.
Few studies compared the diagnostic value of procalcitonin with a combination of other tests including lactate and high-sensitivity C-reactive protein in the prediction of pathogenic bacteremia in emergency department adult patients.
To analyse and compare the ability of procalcitonin (PCT), C-reactive protein (CRP) and leukocytes to differentiate true bacteraemia from contaminated blood cultures in patients seen in the emergency department (ED) for an episode of infectious disease.
Multivariate analysis revealed that development of septic shock, Charlson Comorbidity Index, lower respiratory tract infection, bacteremia (primary or secondary), MRSA, and CRP was significantly associated with fatality.
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.
Death was associated with higher SOFA scores, a higher incidence of bacteremia and admission to the intensive care unit, higher C-reactive protein and phenylalanine levels, worse kidney function, and lower pre-albumin and transferrin levels.
We assessed daily mean levels of albumin, CRP and Hb from 30 days before to 30 days after bacteraemia and correlations between albumin vs. CRP and albumin vs. Hb.
Neutrophil percentages of ≥80, serum creatinine levels of ≥2 mg/dl, and high serum C-reactive protein levels were noted more frequently in patients with invasive infections than in patients with noninvasive infections, as were bacteremia and a high mortality rate.
