Gender Associated Lipid and Apolipoprotein Profile in Patients with Age-Related Macular Degeneration

The role of lipid parameters disorder in the development of age-related macular degeneration (AMD) is unclear. The aim of this study was to analyze lipid profile in these patients and to test the influence of gender on lipid profile of AMD patients, especially in the early and late form of the disease. 82 patients with AMD (mean age 70.3 yrs) and 80 age-matched control subjects were included in this study. Serum lipid and apolipoproteiin levels were determined using standardized methods. AMD patients had significantly higher values of total cholesterol (P=0.000), HDL-cholesterol (P=0.0003) and LDL-cholesterol (P=0.000) compared to control group. Significantly higher values of apo A1 (P=0.039), apo E (P=0.002), total-cholesterol (P=0.000), LDL-chol. (P=0.026), total HDL-chol (P=0.000), HDL3-chol. (P=0.005) and non-HDL-cholesterol (P=0.029) were found in female AMD patients compared to males with AMD. Females with the advanced form of the disease had significantly higher total cholesterol (P=0.006), HDL-C (P=0.004), non HDL-C (P=0.05) and apo E (P=0.014) compared to males with the same form of the disease. There is a significant disorder of lipid parameters in AMD patients especially in females. More severe forms of AMD are followed by the increase of atherogenic lipoproteins and apolipoproteins, and females have higher values of these parameters compared to males with the same form of AMD.
