Changing Italian nosocomial-community trends and heteroresistance in Staphylococcus aureus from bacteremia and endocarditis.
No full textBloodstream infections due to Staphylococcus aureus (BSI) are serious infections both in hospitals and in the community, possibly leading to infective endocarditis (IE). The use of glycopeptides has been recently challenged by various forms of low-level resistance. This study evaluated the distribution of MSSA and MRSA isolates from BSI and IE in 4 Italian hospitals, their antibiotic susceptibility-focusing on the emergence of hVISA-and genotypic relationships. Our results demonstrate that the epidemiology of MRSA is changing versus different STs possessing features between community-acquired (CA)- and hospital-acquired (HA)-MRSA groups; furthermore, different MSSA isolated from BSI and IE were found, with the same backgrounds of the Italian CA-MRSA. The hVISA phenotype was very frequent (19.5%) and occurred more frequently in isolates from IE and in both the MSSA and MRSA strains. As expected, hVISA were detected in MRSA with vancomycin minimum inhibitory concentrations (MICs) of 1-2 mg/l, frequently associated with the major SCCmec I and II nosocomial clones; this phenotype was also detected in some MSSA strains. The few cases of MR-hVISA infections evaluated in our study emonstrated that 5 out of 9 patients (55%) receiving a glycopeptide, died. Future studies are required to validate these findings in terms of clinical impact. © 2011 The Author (s)
Susceptibility of gram positive cocci to teicoplanin. Three year survey (1984-1986) at Perugia University
No full textFrom 1984 to 1986, 1038 Gram positive cocci (865 Staphylococci and 173 Enterococci) have been tested for sensitivity to teicoplanin by the agar diffusion method: only one strain (Staphylococcus haemolyticus) resulted to have no zone of inhibition around the teicoplanin disk. All Staphylococcus haemolyticus strains showed higher MIC: 2.79 mcg/ml after 24h of incubation and 20.50 mcg/ml after 48h. The reduced teicoplanin sensitivity of Staphylococcus haemolyticus was not detected by the agar diffusion test
Treatment of post-traumatic hand Staphylococcus aureus osteomyelitis with oral linezolid
No full textThe Authors report on the use of linezolid for the treatment of three patients with osteomyelitis. All three patients had post-traumatic multisensitive hand bone methicillin-susceptible Staphylococcus aureus osteomyelitis, which did not respond to antimicrobial regimens including drugs in vitro active against the isolated strains. Clinical cure and microbiologic eradication was obtained with oral linezolid in all three patients. Linezolid was well tolerated. Mild thrombocytopenia was observed in one patient at the end of the third week of treatment and it was promptly resolved after the discontinuation of linezolid. Linezolid minimum inhibitory concentrations (MICs) consisted of 2 mg/l for all three S. aureus isolates while the bactericidal activity in vitro was not present up to the linezolid concentration of 32 mg/l. In spite of a lack of in vitro bactericidal activity, linezolid was effective in curing the patients and eradicating the infection. Trough and peak plasma concentrations of linezolid were above the MICs of the isolates. These values ranged from 3.93 to 14.95 mg/l at trough and 5.03 to 25.91 mg/l at peak. The oral bioavailability, pharmacokinetic profile and antibacterial spectrum of linezolid make this oxazolidonone antimicrobial an attractive drug for the treatment of chronic osteomyelitis. Prolonged administration requires careful surveillance for side effects, until these complications are better understood
Nutritional management of stage 5 chronic kidney disease
No full textNutrition is a critical issue in the management of patients with stage 5 chronic kidney disease (CKD). Malnutrition is common among these patients and affects their survival and quality of life. A basic knowledge of the nutritional management of stage 5 CKD is essential for all members of the nephrology team to improve patient care. This paper demonstrates that the needs of haemodialysis patients are more complex than those receiving peritoneal dialysis. © 2011 European Dialysis and Transplant Nurses Association/European Renal Care Association
