Mitochondrial Toxicogenomics for Antiretroviral Management: HIV Post-exposure Prophylaxis in Uninfected Patients.

Mitochondrial genome has been used across multiple fields in research, diagnosis, and toxicogenomics. Several compounds damage mitochondrial DNA (mtDNA), including biological and therapeutic agents like the human immunodeficiency virus (HIV) but also its antiretroviral treatment, leading to adverse clinical manifestations. HIV-infected and treated patients may show impaired mitochondrial and metabolic profile, but specific contribution of viral or treatment toxicity remains elusive.

Safety, efficacy and indications of prescription of maraviroc in clinical practice: Factors associated with clinical outcomes.

Maraviroc is approved for treatment-experienced HIV+ adults in twice-daily administration. Limited data are available on safety, efficacy and use in routine clinical practice, outside of restrictive clinical trials. This retrospective multicenter (27 centers) study included 667 subjects starting a regimen with maraviroc.

Effectiveness and tolerability of abacavir-lamivudine-nevirapine (ABC/3TC/NVP) in a multicentre cohort of HIV-infected, ARV-naïve patients.

Purpose: Very scarce information has been published to date with the combination of ABC/3TC/NVP but it is currently being used in clinical practice in Spain and Portugal. Our aim was to present the clinical experience with this regimen in a cohort of adult HIV-infected antiretroviral (ARV)-naïve patients.

Methods: Retrospective, multicentre, cohort study.

Risk factors for a low linezolid trough plasma concentration in acute infections.

Linezolid is an antibiotic with time-dependent activity, and both the percentage of time that plasma concentrations exceed the MIC and the area under the concentration-time curve over 24 h in the steady state divided by the MIC (AUC24/MIC ratio) are associated with clinical response. The aim of this study was to analyze the linezolid trough plasma concentration (C(min)) and to determine factors associated with a C(min) < 2 mg/liter and other clinically relevant thresholds. Characteristics of 78 patients receiving 600 mg/12 h of linezolid with a C(min) determination at the steady state and within the first 10 days of treatment were retrospectively reviewed.
