RESUMO
OBJECTIVE: Teicoplanin is widely used for the treatment of severe gram-positive infection, aiming to achieve trough serum levels of 20-60 mg/L for patients with severe infection. A standard 400 mg daily dose is frequently associated with sub-therapeutic levels, and we have therefore changed our routine approach to 600 mg daily (following loading doses in each case). We set out to investigate the impact of this dose increase on drug levels and potential side-effects. METHODS: We undertook a retrospective study of 549 consecutive adult Out-Patient Antimicrobial Treatment (OPAT) episodes treated with intravenous teicoplanin. RESULTS: Therapeutic teicoplanin levels were more frequently achieved in patients treated with 600 mg compared to 400 mg daily (68% vs. 37% respectively, p < 0.0001), without an increased frequency of potentially toxic levels, defined as >60 mg/L (6% vs. 8% respectively, p = 0.4). There was no difference in the incidence of neutropaenia, eosinophilia, thrombocytopaenia, acute renal injury or treatment cessation in patients treated with the higher teicoplanin dose. CONCLUSIONS: In the majority of stable adult patients with normal renal function, we advocate a loading regimen (600 mg b.d. for two doses) followed by a 600 mg daily teicoplanin dose in order to achieve therapeutic trough levels.

OBJECTIVES: Provision of outpatient parenteral antimicrobial therapy (OPAT) is an evolving field, facilitating discharge from hospital for selected patients with serious infections. We report on a large OPAT cohort focusing on the practice of supervised parenteral antibiotic administration in the community by patients and relatives, which we collectively term 'self-administration'. To distinguish between healthcare professional OPAT and self-administered OPAT, we have coined the terms H-OPAT and S-OPAT, respectively. PATIENTS AND METHODS: We analysed data on 2059 OPAT episodes collected prospectively over a 13 year time period from 1993 to 2005. RESULTS: Clinical diagnosis, microbiology and antibiotics in this OPAT series are comparable to those previously reported. We identified no excess complications or hospital re-admissions in the S-OPAT group compared with the H-OPAT group. CONCLUSIONS: Self-administration of intravenous antimicrobial therapy, in selected patients under the supervision of a specialist team, is a safe and feasible strategy.
