description | Prior studies have yielded mixed findings concerning the association between apolipoprotein E(<i>APOE</i>)-<i>ε4</i> and serum lipids in patients with Alzheimer’s disease (AD) and healthy individuals. Some studies suggested a relationship between <i>APOEε4</i> and serum lipids in patients with AD and healthy individuals, whereas others proposed that the <i>APOEε4</i> allele affects lipids only in patients with AD. Our study aimed to investigate whether <i>APOE</i> alleles have a distinct impact on lipids in AD. We conducted a comprehensive search of the PubMed and Embase databases for all related studies that investigate <i>APOE</i> and serum lipids of AD from the inception to 30 May 2022. Elevated total cholesterol (TC) and low-density lipoprotein (LDL) levels were found in <i>APOEε4</i> allele carriers compared with non-carriers. No significant differences were found for high-density lipoprotein (HDL) and triglyceride (TG) levels in <i>APOEε4</i> allele carriers compared to non-carriers. Notably, elevated TC and LDL levels showed considerable heterogeneity between patients with AD and healthy controls. A network meta-analysis did not find a distinct effect of carrying one or two <i>APOEε4</i> alleles on lipid profiles. Higher TC and LDL levels were found in <i>APOEε4</i> allele carriers compared with non-carriers, and the difference was more significant in patients with AD than in healthy controls. |
