Abstract

Background: The World Health Organization (WHO) recommends abacavir as the preferred/alternative backbone for 1st line regimens in children with HIV from age 28 days. There are limited data available on safety and tolerability of abacavir in young infants aged <3 months.

Methods: We describe infant and regimen characteristics at the start of abacavir (including drug combinations and dosing) and outcomes up to 12 months after first use of abacavir. Outcomes include:

  • drug discontinuations (defined as interruption of abacavir for >30 days),
  • clinical adverse events (AE, reported from start of abacavir, and up to 30 days after discontinuation of abacavir) and
  • viral load at 6 and 12 (±3) months after start of abacavir

Conclusions: Across children initiating abacavir in early life in Europe, it was safe and well tolerated, and discontinuations for safety concerns were rare. • Viral suppression was below the UN-AIDS 90% target which may reflect challenges of treatment in infancy.
