There were no significant differences between the cases of PJI in patients who had recently used and had not used antibiotics in terms of GLB (33.87 vs. 33.25, P > 0.05), AGR (1.20 vs. 1.13, P > 0.05), fibrinogen (4.45 vs. 4.46, P > 0.05), ESR (50.0 vs. 52.0, P > 0.05), and CRP (36.3 vs. 21.3, P > 0.05). This evidence concerns the gene CRP and juvenile polyposis syndrome.
