Abstract: OBJECTIVES: People living with HIV face several challenges as they age, including the potential for polypharmacy and increased susceptibility to drug-related adverse effects. Thus, effective and well-tolerated regimens with minimal or no drug interactions would be useful in this population. We present real-world effectiveness and safety data for individuals aged >50 years who achieved virological suppression (HIV-1 RNA <50 copies/mL) and switched to dolutegravir/lamivudine (DTG/3TC). METHODS: This retrospective, observational, single-centre study conducted in Portugal included individuals aged >50 years who switched to DTG/3TC while virologically suppressed and had ≥12 months of follow-up. Proportions of individuals maintaining virological suppression were described at 12 months; CD4+ cell counts were described at baseline and 12 months. Descriptive subgroup analyses were performed based on age, sex assigned at birth, and availability of historical genotypic resistance results. RESULTS: [range 99-2659]). No individuals experienced virological failure. Nine (2%) individuals discontinued DTG/3TC for non-treatment-related reasons. Proportions with virological suppression at month 12 were similar between on-treatment subgroups by age, sex assigned at birth, and historical genotypic resistance results availability. CONCLUSIONS: DTG/3TC demonstrated robust effectiveness and a good safety profile in individuals aged >50 years with virological suppression in Portugal.
