A retrospective evaluation of highly active antiretroviral therapy simplification in patients with end-stage renal disease receiving hemodialysis.

Abstract

Antiretroviral (ARV) therapy in people living with HIV (PLWH) and end-stage renal disease (ESRD) on hemodialysis (HD) is complicated, requiring renally adjusted nucleoside reverse transcriptase inhibitors (NRTIs) and daily administration of non-renally eliminated agents. Recent data in PLWH with ESRD on HD demonstrate maintenance of viral suppression (82% with viral loads (VLs) <50 copies/mL) and favorable safety/tolerability profiles after ARV simplification with a fixed dose combination single tablet [elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide (E/C/F/TAF)]. Extrapolation of these data to all F/TAF formulations would allow ARV simplification to most PLWH with ESRD receiving HD. The objective of this retrospective study was to identify if ARV-experienced PLWH with ESRD on HD receiving renally adjusted NRTIs may be simplified to once daily ARV formulations without adverse effects while maintaining viral suppression. This single-center retrospective analysis assessed virologic control (3-12months) and ARV tolerability post-regimen simplification (primarily NRTI once-daily dose adjustment) in PLWH with ESRD on thrice weekly HD receiving human immunodeficiency virus (HIV) care in an ambulatory clinic. Seventeen PLWH with ESRD on HD were included after documented ARV simplification. At 12months, 12 patients (71%) remained undetectable (HIV VL <50 copies/mL) with two additional maintaining viral suppression (<200 copies/mL). One patient remained undetectable at month eight but became non-adherent with viral rebound. Two patients did not complete the 6- and 12-month evaluation after documented nonadherence (N = 1) and an adverse effect (pruritus) (N = 1). At 12months, virologic suppression and tolerability resulted after a simplified ARV regimen including once daily F/TAF was initiated in PLWH with ESRD on thrice weekly HD with a reduction in pill burden.
