In addition, a previous study by Kheir et al. demonstrated that culture-negative PJI cases had lower CRP values than PJI cases caused by Gram-negative organisms, antibiotic-resistant organisms, Staphylococcus aureus, and Streptococcus species; they also had lower WBC counts than PJI cases caused by Staphylococcus aureus and Streptococcus species [20]. Here, CRP is linked to juvenile polyposis syndrome.
