Influence of low-pathogenicity microbial etiology. Serum concentrations of CD64 (A), procalcitonin (B), CRP (C) and white blood count (D) among patients with flare of rheumatic arthritis (FRA), crystal-induced arthritis (CIA), septic arthritis caused by coagulase negative staphylococci (SA CNS) and septic arthritis with other microbiological agent (SA other). Horizontal lines indicate cut-off values for CD64 (A) and PCT (B), derived from ROC curve analysis. PCT values above 5 mg/L are plotted as 5 mg/L.
