ABSTRACT
OBJECTIVE:
To evaluate the relationship between plasma biomarkers of systemic inflammation and incident age-related macular degeneration (AMD) in persons with the AIDS.DESIGN:
Case-control study.METHODS:
Participants with incident intermediate-stage AMD (Nâ=â26) in the Longitudinal Study of the Ocular Complications of AIDS (LSOCA) and controls (Nâ=â60) without AMD. Cryopreserved baseline plasma specimens were assayed for biomarkers of inflammation, including high-sensitivity C-reactive protein (CRP), interleukin (IL)-6, interferon-γ inducible protein (IP)-10, soluble CD14 (sCD14), soluble CD163 (sCD163), and intestinal fatty acid-binding protein (I-FABP).RESULTS:
After adjustment for age, sex, and race/ethnicity, baseline meanâ±âstandard deviation (SD) log10(mg/ml) plasma levels of CRP (0.52â±â0.60 vs. 0.20â±â0.43; Pâ=â0.01) and meanâ±âSD log10(pg/ml) plasma levels of sCD14 (6.31â±â0.11 vs. 6.23â±â0.14; Pâ=â0.008) were significantly higher among cases (incident AMD) than among controls (no AMD). There was a suggestion that meanâ±âSD baseline log10(pg/ml) plasma IL-6 levels (0.24â±â0.33 vs. 0.11â±â0.29; Pâ=â0.10) might be higher among cases than controls. In a separate analysis of 548 participants in LSOCA, elevated baseline levels of plasma inflammatory biomarkers were associated with a greater risk of mortality but not with an increased risk of incident cataract.CONCLUSION:
These data suggest that systemic inflammatory biomarkers are associated with incident AMD but not incident cataract in persons with AIDS, and that systemic inflammation may play a role in the pathogenesis of AMD.
