Vancomycin-induced thrombocytopenia is a rare adverse reaction that may be overlooked because no specific diagnostic test is currently available. We herein report a patient with vancomycin-induced immune thrombocytopenia who was diagnosed by the detection of vancomycin-dependent anti-platelet antibody with flow cytometry. An IgG antibody in the patient's serum reacted with platelets only in the...
The aim of this study was to investigate the molecular characteristics of induced vancomycin resistance in Staphylococcus haemolyticus. Autolytic properties and phenotypic characteristics of passage-selected vancomycin-resistant S. haemolyticus strains were examined. In addition, expression of autolysis-related genes (atl, lrgAB, sarA and lytS) was investigated using the RNase protection assay ...
Vancomycin is a front-line antibiotic used for the treatment of nosocomial infections, particularly those caused by methicillin-resistant Staphylococcus aureus. Despite its clinical importance the global effects of vancomycin exposure on bacterial physiology are poorly understood. In a previous transcriptomic analysis we identified a number of Zur regulon genes which were highly but transiently...
introduction: one of the most important agents in hospital-acquired infections is staphylococcus aureus. treatment of methicillin-resistant s. aureus (mrsa) infections with decreased susceptibility to vancomycin has recently been more difficult. the aim of this study was to evaluate the possible presence of vancomycin intermediate s. aureus (visa) and vancomycin- resistant s. aureus (vrsa) and ...
Eighty clinical microbiology laboratories in Taiwan were evaluated for proficiency in the determination of vancomycin susceptibility of enterococci. Each laboratory was given 1 vancomycin-sensitive isolate and 3 vancomycin-resistant enterococci (VRE) isolates to determine the levels of vancomycin resistance. Among a total of 240 tests performed, 153 (63.8%) correctly determined the levels of va...
This study was undertaken to assess whether oropharyngeal vancomycin may control oropharyngeal carriage and lower airway infection due to methicillin-resistant Staphylococcus aureus (MRSA) acquired in the intensive care unit (ICU). Secondary endpoints were the emergence of vancomycin-resistant enterococci, vancomycin-intermediate S. aureus and vancomycin consumption. A total of 84 patients, adm...
Strain D958, a methicillin-resistant Staphylococcus aureus strain with reduced susceptibility to vancomycin, was isolated from a 69-year-old Saudi male patient presenting with severe sepsis immediately after admission. Despite high serum levels of vancomycin, the same S. aureus strain was isolated from five blood culture sets during 1 week. Treatment failure under therapeutic levels of vancomyc...
BACKGROUND Recent studies have reported a greater probability of vancomycin treatment failure in methicillin-resistant Staphylococcus aureus (MRSA) bloodstream infections caused by strains with a vancomycin MIC ≥ 1.5 mg/L. However, previous reports included patients treated without adjustments based on vancomycin serum levels and with different methods to evaluate MICs, which may render differe...
The purpose of the present study was to assess the cutaneous response to intradermally administered vancomycin in healthy adults and to determine whether the magnitude of the cutaneous response correlated to the severity of "red man syndrome" (RMS) following intravenous administration of vancomycin to the same subjects. Eleven healthy males were skin tested with intradermally administered hista...
Vancomycin is one of the older antibiotics that has been now in clinical use close to 60 years. Earlier on, vancomycin was associated with many side effects including vestibular and renal, most likely due to impurities contained in early vancomycin lots. Over the years, the impurities have been removed and the compound has now far less vestibular adverse effects, but still possesses renal toxic...
