Inflammatory syndrome was less pronounced (erythrocyte sedimentation rate [ESR]: 62 vs. 81 mm at 1 h; p = 0.03; C-reactive protein [CRP]: 60 vs. 147 mg/L; p = 0.0003) and less common (ESR < 30 mm: 23% vs. 0%; p = 0.01; CRP < 10 mg/L: 23% vs. 0%; p = 0.005) compared to patients with SA infections. This evidence concerns the gene CRP and infection.
