Risk factors analysis of dyskinesias in patients with Parkinson's disease / 中国综合临床

ABSTRACT

Objective To explore the risk factors of dyskinesias in Parkinson' s disease (PD) patients.Methods Patients with PD who had taken levodopa at least 1 month were recruited according to the United Kingdom Brain Bank (UKBB) Criteria..All patients were divided into dyskinesias group and non-dyskinesias group according to the clinical definition of dyskinesia.The parameters including gender,age,age onset,duration,body weight,UPDRS scale score,and treatment parameter,such as the maximum daily dose of levodopa,the cumulative time of medication of levodopa,levodopa dose per weight of patients with dyskinesias were recorded.Multivariate logistic regression analysis was used to analyze risk factors of dyskinesias.The patients were divided into dyskinesias and no dyskinesias groups based on presence of motor complications.Results The incidence rate of dyskinesias was 7.8％ (11/142) in all 142 patients.Of which,9 cases were with peak-dose dyskinesia,and 2 cases with both wearing-off and dyskinesia.There were statistically significant difference between dyskinesias group and non-dyskinesias group in terms of sex,weight,the maximum daily dose of levodopa and levodopa dose per weight(P ＜ 0.05).The same results appeared between wearing-off group and wearing-off with dyskinesia group (P ＜ 0.05).Multivariate Logistic regression analysis showed that total dose of levodopa(OR =1.846,95％ CI1.234-2.762,P =0.003) and levodopa dose per weight were independentriskfactors(OR=0.991,95％CI0.984-0.999,P=0.033).Conclusion The risk factors of dyskinesias in Parkinson's disease is closely linked to total dose of levodopa and levodopa dose per weight.
