Insights
A polygenic risk score (PRS) is linked to osteoporosis in people with HIV (PLWH). This genetic risk factor is associated with low bone mineral density (BMD) independent of traditional risk factors.
Area of Science:
- Genetics
- Bone Metabolism
- Infectious Diseases
Background:
- Bone mineral density (BMD) loss is a concern for people with HIV (PLWH).
- The association between polygenic risk scores (PRS) and low BMD in PLWH remains uninvestigated.
Purpose of the Study:
- To determine if a PRS is associated with low BMD in PLWH.
- To assess the PRS's independent contribution to osteoporosis risk in PLWH.
Main Methods:
- Utilized data from the Swiss HIV Cohort Study (2011-2020).
- Included 438 participants of European descent with multiple dual x-ray absorptiometry (DXA) measurements.
- Calculated a genome-wide PRS from 9413 single-nucleotide polymorphisms associated with low BMD.
Main Results:
- Participants with an unfavorable osteoporosis PRS showed significantly higher odds of osteoporosis.
- Osteoporosis odds ratios (ORs) for the top vs. bottom PRS quintile were 4.76 (univariable) and 4.13 (multivariable).
- PRS association remained significant after adjusting for traditional and HIV-related factors, including tenofovir disoproxil fumarate exposure.
Conclusions:
- A BMD-associated PRS is independently associated with osteoporosis in PLWH.
- Genetic predisposition, assessed by PRS, plays a role in osteoporosis development in this population.
- Findings highlight the importance of genetic factors in managing bone health in people with HIV.
Background:
Bone mineral density (BMD) loss may be accelerated in people with HIV (PLWH). It is unknown whether a polygenic risk score (PRS) is associated with low BMD in PLWH.
Methods:
Swiss HIV Cohort Study participants of self-reported European descent underwent ≥2 per-protocol dual x-ray absorptiometry (DXA) measurements ≥2 years apart (2011-2020). Univariable and multivariable odds ratios (ORs) for DXA-defined osteoporosis were based on traditional and HIV-related risk factors and a genome-wide PRS built from 9413 single-nucleotide polymorphisms associated with low BMD in the general population. Controls were free from osteoporosis/osteopenia on all DXA measurements.
Results:
We included 438 participants: 149 with osteoporosis and 289 controls (median age, 53 years; 82% male, 95% with suppressed HIV RNA). Participants with unfavorable osteoporosis PRS (top vs bottom quintile) had univariable and multivariable-adjusted osteoporosis ORs of 4.76 (95% CI, 2.34-9.67) and 4.13 (1.86-9.18), respectively. For comparison, hepatitis C seropositivity, 5-year tenofovir disoproxil fumarate exposure, and parent history of hip fracture yielded univariable osteoporosis ORs of 2.26 (1.37-3.74), 1.84 (1.40-2.43), and 1.54 (0.82-2.9).
Conclusions:
In PLWH in Switzerland, osteoporosis was independently associated with a BMD-associated PRS after adjustment for established risk factors, including exposure to tenofovir disoproxil fumarate.
