Vancomycin MIC plus heteroresistance and outcome of methicillin-resistant Staphylococcus aureus bacteremia: trends over 11 years.
Vancomycin MICs (V-MIC) and the frequency of heteroresistant vancomycin-intermediate Staphylococcus aureus (hVISA) isolates are increasing among methicillin (meticillin)-resistant Staphylococcus aureus (MRSA) isolates, but their relevance remains uncertain. We compared the V-MIC (Etest) and the frequency of hVISA (Etest macromethod) for all MRSA blood isolates saved over an 11-year span and cor...
متن کاملMicroscopic polyangiitis following recurrent Staphylococcus aureus bacteremia and infectious endocarditis.
Secondary vasculitis resulting from unusual pathologic expressions of infections has been described and has important clinical significance. Infectious agents have also been implicated in the pathogenesis of different primary systemic necrotizing vasculitides. Infectious endocarditis is of particular importance in the differential diagnosis of a patient presenting with ANCA associated vasculiti...
متن کاملCommunity-associated Methicillin-resistant Staphylococcus aureus Bacteremia and Endocarditis among HIV Patients: A cohort study
BACKGROUND HIV patients are at increased risk of development of infections and infection-associated poor health outcomes. We aimed to 1) assess the prevalence of USA300 community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) among HIV-infected patients with S. aureus bloodstream infections and. 2) determine risk factors for infective endocarditis and in-hospital mortality amo...
متن کاملVancomycin heteroresistance and methicillin-resistant Staphylococcus aureus.
Heteroresistance refers to the presence, within a larger population of fully antimicrobial-susceptible microorganisms, of subpopulations with lesser susceptibility. This phenomenon has been described in a wide range of microorganisms, but much recent attention has been directed toward its expression in Staphylococcus aureus. Although it has long been known that resistance to methicillin is char...
متن کاملNative aortic valve endocarditis secondary to Staphylococcus aureus bacteremia.
A 7-year-old boy presented with cellulitis over the medial aspect of the left upper thigh and pyomyositis of the left vastus lateralis accompanied by severe restriction of the left hip joint. These complaints had developed over the last 12 days. MRI detected osteomyelitis of the proximal metaphysis of the left femur with mild left hip joint effusion. His Hb was 10.2 g/dL and WBC count was 29,00...
