Scholarcy highlights

  • Baseline genotyping is part of standard-of-care treatment
  • Attention is typically focused on determining whether resistance to the protease inhibitors and reverse transcriptase inhibitors occurs
  • PI and RTI drug resistance genotyping was performed on blood samples collected between 2005 and 2015 from 772 treatment-naïve Victorian patients infected with HIV within the previous 12 months
  • In the period 2005–10, 39 of 343 patients had at least one PI- or RTI-associated mutation, compared with 34 of 429 during the period 2011–15
  • Compared with 2005–10, during 2011–15 there was a significant decline in the prevalence of the non-nucleoside-associated mutation K103N and the nucleoside-associated mutations at codons M41 and T215
  • One patient was detected with a major INI resistance mutation, namely G118R
  • We acknowledge their continuing connection to their culture, their contribution to our shared knowledge, and pay our respects to their Elders past and present
