Study summary

The concentration of the third agent in antiretroviral therapy [Non Nucleoside Reverse Transcriptase Inhibitor (NNRTI), or boosted Protease inhibitor (PI) ] is different according to the body weight or body composition and therapeutic monitoring may be necessary in overweight HIV patients.

The investigators aim at measuring the individual trough concentrations of interest [at steady state for NNRTI and boosted PI] in overweight and normal weight HIV+ patients.

Read the detailed description

Our primary endpoint is the individual trough concentrations of interest at steady state for NNRTI or boosted PI; Principal outcome measure: comparison of the concentrations between patients \<25kg/m2 and patients\<25kg/m2

Secondary endpoints:

  • Occurrence of virologic failure
  • Occurrence of clinical/biological adverse events
  • Percentage of patients with concentration within the therapeutic range
  • Body composition Secondary outcome measures: comparison of the occurrence of virologic failure, occurrence or adverse event, patients with concentration within the therapeutic range between groups. Correlation between body composition and concentration.

Methodology, study design:

open-labelled monocentric study.

Sample size:

It will be a descriptive experimental study involving 120 overweight subjects, 120 normal weight subjects

Inclusion criteria :

  • Patients with HIV+
  • Patients aged more than 18 years old.
  • Patient giving its well-informed and free consent.

Study design :

Plasma concentration was performed during the usual clinical follow-up. Study duration: 12 months Duration for a patient: 1 day Investigating center and participating units: one center enrolling the patients and the lab performing drug dosages.
