The Association of Lipoprotein Parameters and C-Reactive Protein in Patients with Age-Related Macular Degeneration

Background: Age-related macular degeneration (AMD) is the most common cause of visual impairment in individuals over 50 years of age, with the prevalence of 0.05% before the age of 50 rising to 30% after 74 years of age. An elevated concentration of plasma lipoproteins is considered to be one of the risk factors of AMD development. The aim of our study was to analyze the concentration of serum lipoproteins-total cholesterol, high-density lipoprotein (HDL), low-density lipoprotein (LDL), non-LDL cholesterol and triglycerides - as well as apolipoproteins - apoA1, apoB and Lp(a) - along with C-reactive protein (CRP) in patients with AMD in order to explore the possible association of lipid and inflammatory parameters with the pathogenesis of AMD. Material and Methods: In the cross-sectional study in the University clinical setting, 79 patients with AMD, aged 71.47 +/- 7.02 years, and 84 aged-matched control subjects were included. The patients underwent complete ophthalmological examination including visual acuity assessment, color fundus photography and fluorescein angiography. Results: Statistical processing data revealed significantly higher total (p = 0.0002), LDL (p = 0.023), non-HDL cholesterol (p = 0.0014) and CRP (p = 0.049) values in AMD patients compared to control subjects. Conclusions: Based on the obtained results, it may be concluded that lipid status disorder and inflammation could play an important role in the development of AMD in elderly people.
