When all five single-nucleotide polymorphisms (SNPs) (at positions -639, -292, -163, +1320, and +3415 [all relative to CISH]) within the CISH-associated locus were considered together in a multiple-SNP score, we found an association between CISH genetic variants and susceptibility to bacteremia, malaria, and tuberculosis (P=3.8x10(-11) for all comparisons), with -292 accounting for most of the association signal (P=4.58x10(-7)).
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.
Univariate analysis revealed that infection was more frequent in patients with MRSA-carriage (p < 0.001), in case of previous catheter-related infection (p < 0.05) and of bacteremia or bacteriuria in the period of 3 months before catheter implantation (p < 0.001).
<b>Conclusions:</b> Although MRSA were uncommon, we found high genetic diversity of methicillin susceptible <i>S. aureus</i> causing bacteremia in Mozambican children, associated with high resistance to the most available antibiotics in this community.
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).
The score demonstrated very good discrimination (c statistic 0.8662, 95% CI 0.824-0.909) and was superior to the APACHE II (P = 0.043) and the Pitt bacteremia (P < 0.001) scores.
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.
Patients with ColRAN bacteraemia had higher APACHE II scores, but the two groups showed no significant differences in 14-day mortality (10.3% vs. 10.3%) or 28-day mortality (15.5% vs. 15.0%).
We aimed to evaluate a PCR-based rapid diagnosis of methicillin resistance (GeneXpert MRSA) after early detection of S. aureus bacteraemia using matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS).
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.
A blood culture should be considered for patients with ABSSSI with diabetes mellitus or chronic kidney disease or those exhibiting abnormal CRP, glucose, or albumin levels because of the positive correlation between bacteremia and mortality.
Recently (2009-2010), the distribution of predominant MRSA clones decreased, whilst the prevalence of non-predominant MSSA clones increased, especially for the isolates causing bacteraemia.
In addition, molecular methods able to detect and differentiate S. aureus and MRSA (SA/MRSA) directly from blood cultures are becoming a useful tool for rapid detection of bacteremia caused by MSSA and MRSA.
