Effectiveness and safety of HAART regimens containing tenofovir DF + saquinavir or fosamprenavir in HIV patients: sub-analysis from PROTECTION study
Journal of the International AIDS Society volume 11, Article number: P78 (2008)
Purpose of the study
The concomitant use of tenofovir DF (TDF) in combination with different protease inhibitors (PIs) has been widely investigated, especially in treatment-naïve patients. Although some data exist in treatment-experienced patients receiving TDF with the commonly used PIs, such as atazanavir or lopinavir, data from other TDF+PI combinations are lacking.
The PROTECTION cohort included retrospective data from 1,428 HIV patients treated with different TDF+PI combinations from 80 HIV clinics in Spain. We have performed a sub-analysis of those patients whose HAART regimens included at TDF in combinations including saquinavir (SQV) or fosamprenavir (FPV).
Summary of results
The most prevalent adverse event was diarrhoea in the SQV cohort (11%) and hypertrigliceridaemia in the FPV cohort (4%). Only four patients (2%) withdrew their treatment due to an adverse event. One patient (0.5%) with baseline mild renal impairment (GFR: 63 mL/min) withdrew his treatment due to a grade 1 GFR decrease.
In this cohort, concomitant use of TDF with SQV or FPV was associated with good tolerability and an adequate rate of viral effectiveness, suggesting these combinations are suitable as rescue therapy in highly treatment-experienced patients.
