Arnold et al. have found an increase in CRP levels (median 174 mg/L) in patients with Methicillin-resistant Staphylococcus aureus (MRSA) infection when compared to CRP levels (118 mg/L) in patients with Methicillin-sensitive Staphylococcus aureus (MSSA) infection as well as Branson et al. (CRP 147 mg/ L on admission versus 88 mg/L).35,36 Concurrent AHOM and septic arthritis can lead to increased inflammatory markers, prolonged bacteraemia and hospital duration.9,16 In this study, neither MRSA nor concurrent infection seemed to be a significant marker of a severe course. The gene discussed is CRP; the disease is Methicillin-Susceptible Staphylococcus Aureus Infection.
