BACKGROUND This study explored the impact of genetic polymorphisms in cytochrome P450 (CYP) enzymes and transporters on the plasma trough concentration of imatinib mesylate (IM) and clinical response in chronic myeloid leukemia (CML). PATIENTS AND METHODS In total, 82 patients with CML who had been administered 400 mg IM daily for over 6 months were genotyped for 11 single-nucleotide polymorp...
Trastuzumab is a therapeutic monoclonal antibody against the Her2 oncoprotein, which is over-expressed in approximately 30% of breast cancers, and is now used routinely in the management of early and metastatic Her2+ disease. However, not all Her2+ breast cancer patients respond to trastuzumab and the pharmacodynamic and pharmacokinetic parameters behind this variation in response are unknown. ...
Vancomycin susceptibility of methicillin-resistant Staphylococcus aureus has been changed over time and its average minimum inhibitory concentration increased from 1.5 to 1.75 mg/L. A recently published guideline by the American Society of Health Pharmacist recommended a daily dose of 15-20 mg/kg every 8 to 12 hours of vancomycin to achieve a trough concentration between 15-20 mg/L for treatmen...
Methicillin-resistant Staphylococcus aureus (MRSA) is now endemic in many hospitals. Infection with MRSA is more frequent in the intensive care unit (ICU) than in general wards. Therefore, appropriate treatments for MRSA infections will lead to good outcomes in the ICU. Teicoplanin is an anti-MRSA agent. Recently, it was recommended at a new target trough concentration of 15-30 µg/mL. However, ...
OBJECTIVES The incidence of methicillin-resistant Staphylococcus aureus (MRSA) infections in intensive care units in Malaysia is significant. Invasive MRSA infections are commonly treated with vancomycin. In clinical practice, the serum vancomycin trough concentration is used as a surrogate marker of vancomycin efficacy. A low concentration of vancomycin may result in less effective therapy and...
The pharmacokinetics and safety of an intravenous hydroxypropyl-beta-cyclodextrin solution of itraconazole administered for 7 days followed by itraconazole oral solution administered at 200 mg once or twice daily for 14 days were assessed in 17 patients with hematologic malignancies. Steady-state plasma itraconazole concentrations were reached by 48 h after the start of intravenous treatment. T...
Piritrexim, an orally administered, lipid-soluble antifolate, was evalu ated in a multi-institutional phase I trial in children. The starting dose was 10 mg/m2/dose administered every 8 h daily for 5 days for 3 consecutive weeks, with dose escalations in increments of 5 mg/m2/dose. Eighteen patients (16 with metastatic sarcoma, 1 with acute lymphoblastic leukemia, and 1 with a brainstem glioma)...

We measured hair and plasma concentrations of isoniazid among sixteen children with tuberculosis who underwent personal or video-assisted directly observed therapy and thus had 100% adherence. This study therefore defined typical isoniazid exposure parameters after two months of treatment among fully-adherent patients in both hair and plasma (plasma area under the concentration-time curve, AUC,...
In individuals with incomplete suppression of HIV replication, a major clinical challenge is to establish which agents retain significant antiviral activity. Measurements of both plasma concentration and resistance of selected antiretro-viral agents are widely available. Clinical studies have shown short-term virologic benefit associated with the use of resistance testing in drug-experienced pa...
