[Choice of initial regimen for antiretroviral-naïve HIV patients: Analysis of motivation]. / Analyse des motivations du choix des antirétroviraux (ARV) prescrits chez des patients infectés par le VIH (PVVIH) naïfs.

ABSTRACT

OBJECTIVE: Several therapeutic combination antiretroviral therapy regimen are available for initial treatment in naïve HIV infected patients. The choice of a particular regimen remains often subjective. The aim of this study was to determine factors associated with the choice of molecules in initial ARV prescriptions. METHODS: From 01/01 to 30/10/2014, every initial cART prescription was analyzed regarding patients and physicians characteristics. Then, prescriptions were evaluated by an independent committee of ART prescribers. RESULTS: One hundred and thirty two consecutive initial prescriptions by 34 physicians of 11 medical centers were included 71 M, migrants 57 %, MSM 21 %, CD4<200/mm3 26 %, HIV RNA>100 000 cp/mL (33 %). cART regimen were NRTI/PI (43 %), NRTI/NNRTI (29.5 %), NRTI/integrase inhibitor (23 %). 75 % of initial cART regimen were consistent with expert guidelines recommendations. The choice of initial cART was not influenced by the type of HIV contamination risk group, patient's geographic origin, CD4 levels. In contrast, working or not (P=0.007), pregnancy wish (P=0.07), pregnancy (P=0.001), HIV RNA levels (P=0.02) and HIV primary infection (P=0.049) influenced the initial choice. Neither physician's age, nor physician's experience influenced this choice. The prescription's non accordance to 2013 French guidelines was mainly related to integrase inhibitor utilisation (P= 0.0001). CONCLUSION: Overall, cART initial choice is mostly consistent with guidelines. Primary HIV infection, procreation features and high viral load are the main factors influencing this choice. New regimen with better tolerability is prescribed even if it is not yet included in the guidelines.
