- Abstract
Introduction. Staphylococcus aureus is a major cause of skin and soft tissue infections, osteomyelitis, septic arthritis, pneumonia, bacteremia, endocarditis. Both community-associated and nosocomial infections with S. aureus have increased in the past years and its distribution is different globally. We aim to describe the frequency of S. aureus infections in hospitalized patients in Médica Sur in Mexico City. Material and Methods. We conducted a cross-sectional study at Fundación Clínica Médica Sur in Mexico City. The eligible patients were hospitalized from January 2016 to January 2018, S. aureus were isolated from their clinical specimens submitted to Department of Microbiology. Results. We analyzed 128 cases of S. aureus isolates, 124 (81%) were methicilin-sensitive S. aureus (MSSA) while 24 (18%) were methicilinresistant S. aureus (MRSA) infections. We further classified S. aureus isolates in community-acquired (CA) 61.7%, nosocomial 26.6% and health-acquired (HA) 11.7%. There was no statistically significant difference in frequency of MRSA infections by genre (p=0.333), patients with co-morbidities (p=0.606) and predisposing factors such as implanted device or catheter (p=0.807), hospitalization more than 72 hours (p=0.950) or previous surgery (p=0.940). Clinical outcomes between MSSA and MRSA infections were also similar between both groups Discussion. Our data suggests that the frequency of CA-MRSA in hospitalized patients is relevant. Despite of this, in our population MRSA infections were not significantly different from those who had MSSA.
