The pathogenesis of lipodystrophy in people living with HIV (PLWHIV) receiving antiretrovirals appears to be multifactorial and may involve genetic factors; however, it is not yet fully understood. We verified the association between single nucleotide polymorphisms in the APOC3-rs2854116, ESR2-rs3020450, HFE-rs1799945 and MMP1-rs1799750 genes and lipodystrophy and its subtypes in PLWHIV receiving antiretroviral. Design: cross-sectional study. Lipodystrophy definition was based on self-report. Genotyping of the polymorphisms was performed using real-time polymerase chain reaction. Lipodystrophy was reported in 204/404 participants (51%), being 89/204 with mixed lipodystrophy, 72/204 with lipohypertrophy, and 43/204 with lipoatrophy. There was no association between APOC3, HFE, and MMP1 polymorphisms and lipodystrophy. The frequency of AA genotype ( Participants with lipoatrophy had higher frequency of the AA genotype and the A allele of the ESR2-rs3020450 polymorphism. In addition, viral load >40 copies/mL and current use of zidovudine were associated with lipoatrophy, suggesting a potential involvement of this genetic variant in the pathogenesis of lipoatrophy in PLWHIV receiving antiretroviral.
