BACKGROUND Dalbavancin is a long-half-life (9-12 days) glycopeptide, now in Phase 3 development. Its pharmacokinetics may facilitate home intravenous therapy, early discharge and long prophylaxis. METHODS Dalbavancin and comparators were tested in vitro against staphylococci and streptococci to determine (i) activity and (ii) the comparability of agar dilution MICs by the BSAC and the NCCLS m...

Removal, by selective reduction, of the acetylglucosamine from teicoplanin A2-2 (CTA/2) produced the 34-de(acetylglucosaminyl)-34-deoxy pseudoaglycone (II). This compound was more active in vitro than CTA/2 against coagulase-negative staphylococci (CNS). Amide derivatives obtained by condensation of the carboxyl group of II with primary amines were particularly active against Streptococcus pyog...

The concentrations of teicoplanin in serum, pericardium, pericardial fluid and thoracic wall fat were measured in patients undergoing cardio-pulmonary bypass (CPB) after the administration of a single i.v. 12 mg/kg dose. Five minutes after the start of CPB, teicoplanin serum concentrations decreased by, on average, 35% (95% confidence interval (CI): 28-42%) and remained significantly lower than...

We studied the effects of coating titanium implants with teicoplanin and clindamycin in 30 New Zealand White rabbits which were randomly assigned to three groups. The intramedullary canal of the left tibia of each rabbit was inoculated with 500 colony forming units of Staphylococcus aureus. Teicoplanin-coated implants were implanted into rabbits in group 1, clindamycin-coated implants into rabb...

Central nervous system (CNS) infiltration in a case of promyelocytic leukemia Sir, CNS infiltration is occasionally seen in acute myelogenous leukemia (AML); it is usually associated with those cases that present a monocytic component. Some investigators propose cranial irradiation for all AML patients not undergoing bone marrow transplantation, in order to prevent recurrence of the initial dis...

Teicoplanin (TP) pharmacokinetics was assessed in a critically ill patient during albumin dialysis (AD), which was performed with the molecular adsorbent recirculating system. After a 1200-mg loading dose (24 mg/kg), doses of 1200 and 1000 mg (20 mg/kg) on day 2 and 3, respectively, were administered during two cycles of AD. The mean TP peak and trough concentrations amounted to 99.3 and 21.4 µ...
