| Sumario: | Abstract Brain cholesterol metabolism has been described as altered in Parkinson’s disease (PD) patients. Serum lipid levels have been widely studied in PD with controversial results among different populations and age groups. The present study is aimed at determining if the serum lipid profile could be influenced by the genetic background of PD patients. We included 403 PD patients (342 sporadic PD patients, 30 GBA-associated PD patients, and 31 LRRK2-associated PD patients) and 654 healthy controls (HCs). Total cholesterol, HDL, LDL, and triglycerides were measured in peripheral blood. Analysis of covariance adjusting for sex and age (ANCOVA) and post hoc tests were applied to determine the differences within lipid profiles among the groups. Multivariate ANCOVA revealed significant differences among the groups within cholesterol and LDL levels. GBA-associated PD patients had significantly lower levels of total cholesterol and LDL compared to LRRK2-associated PD patients and HCs. The different serum cholesterol levels in GBA -associated PD might be related to diverse pathogenic mechanisms. Our results support the hypothesis of lipid metabolism disruption as one of the main PD pathogenic mechanisms in patients with GBA-associated PD. Further studies would be necessary to explore their clinical implications. |
