Serological Profiles of Urate, Paraoxonase-1, Ferritin and Lipid in Parkinson's Disease: Changes Linked to Disease Progression.
Summary of "Serological Profiles of Urate, Paraoxonase-1, Ferritin and Lipid in Parkinson's Disease: Changes Linked to Disease Progression."
Background: Oxidative stress plays a role in the pathogenesis of neuronal death. Serum levels of urate or lipid were associated with the incidence of Parkinson's disease (PD). Objective: We compared urate, paraoxonase-1 (PON1), iron, ferritin and lipid in sera of 119 PD patients and 120 healthy controls matched by age, sex and body mass index. We aimed to elucidate whether those serological data are correlated with disease progression. Results: Mean age (SD) of PD patients was 73.4 (8.7) years. Mean Yahr stage (SD) was 3.2 (0.9). Mean disease duration (SD) was 6.9 (5.1) years. Mean dose of L-DOPA (SD) was 355 (157) mg/day. As compared to controls, serum levels of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), urate and PON1 activity were significantly reduced, and serum ferritin levels were significantly increased in male and female PD patients. Serum urate levels and PON1 activities were inversely related, and serum ferritin levels were correlated with Yahr stage and PD duration in men and women. Serum levels of TC and LDL-C were inversely related to Yahr stage or PD duration in female patients. Conclusions: Our studies indicated serological profiles of urate, PON1, ferritin, TC and LDL-C in PD patients. These serological changes were linked to PD progression. Metabolism of lipid, oxidant- and antioxidant-related substances may contribute to the pathogenesis and the progression of PD.

Medical and Biotech [MESH] Definitions
Mptp Poisoning
A condition caused by the neurotoxin MPTP which causes selective destruction of nigrostriatal dopaminergic neurons. Clinical features include irreversible parkinsonian signs including rigidity and bradykinesia (PARKINSON DISEASE, SECONDARY). MPTP toxicity is also used as an animal model for the study of PARKINSON DISEASE. (Adams et al., Principles of Neurology, 6th ed, p1072; Neurology 1986 Feb;36(2):250-8)
Urate Oxidase
An enzyme that catalyzes the conversion of urate and unidentified products. It is a copper protein. The initial products decompose to form allantoin. EC 1.7.3.3.
Parkinsonian Disorders
A group of disorders which feature impaired motor control characterized by bradykinesia, MUSCLE RIGIDITY; TREMOR; and postural instability. Parkinsonian diseases are generally divided into primary parkinsonism (see PARKINSON DISEASE), secondary parkinsonism (see PARKINSON DISEASE, SECONDARY) and inherited forms. These conditions are associated with dysfunction of dopaminergic or closely related motor integration neuronal pathways in the BASAL GANGLIA.
Parkinson Disease, Postencephalitic
Parkinsonism following encephalitis, historically seen as a sequella of encephalitis lethargica (Von Economo Encephalitis). The early age of onset, the rapid progression of symptoms followed by stabilization, and the presence of a variety of other neurological disorders (e.g., sociopathic behavior; TICS; MUSCLE SPASMS; oculogyric crises; hyperphagia; and bizarre movements) distinguish this condition from primary PARKINSON DISEASE. Pathologic features include neuronal loss and gliosis concentrated in the MESENCEPHALON; SUBTHALAMUS; and HYPOTHALAMUS. (From Adams et al., Principles of Neurology, 6th ed, p754)
Lipidoses
Conditions characterized by abnormal lipid deposition due to disturbance in lipid metabolism, such as hereditary diseases involving lysosomal enzymes required for lipid breakdown. They are classified either by the enzyme defect or by the type of lipid involved.
