Low plasma uric acid level in Parkinson's disease.

Abstract

Earlier studies suggest that low plasma uric acid level is a risk factor for Parkinson's disease (PD), and that uric acid associates with iron-binding proteins. We therefore decided to examine plasma uric acid levels and markers of peripheral iron metabolism in PD patients and healthy controls. For the study, 40 patients with PD and 29 controls underwent clinical screening, laboratory testing, and body mass index (BMI) measurement. The average consumption of different foodstuffs and dairy products was estimated. Plasma uric acid level was significantly lower in the patients than in the controls. There were no significant differences in the levels of plasma iron parameters, but plasma uric acid correlated strongly with serum ferritin both in the patient and the control group. The BMI was slightly lower in the patients compared with the controls despite equal daily calorie consumption. Plasma uric acid level is low in patients with PD, which may have implications for both the disease pathogenesis and treatment recommendations.
