Abstract:
Objective:To explore the related factors affecting the prognosis of patients with tardive dyskinesia, in order to find the risk factors of poor prognosis.Methods:A retrospective cohort study was implemented to collect the data of 113 patients with tardive dyskinesia from the movement disorders clinic of the Department of Neurology, Peking Union Medical College Hospital by telephone follow-up. The main variables studied included gender, age, educational level, living environment, job, cigarette smoking, alcohol drinking, hypertension, diabetes, medication type, interval from taking medicine to dyskinesia, course of dyskinesia and intervention measures. The data were analyzed by the statistical software SPSS 25.0. The quantitative data analysis was done by normality test and descriptive statistics, and the qualitative data analysis was done by χ 2 test or Fisher exact probability test. The variables with P≤0.01 in univariate analysis were included in multivariate Logistic regression analysis. Results:Among the 113 patients, 16 patients (14.16%) were cured, 27 patients (23.89%) had obvious improvement, 25 patients (22.12%) had slight improvement, 26 patients (23.01%) had no obvious change, 15 patients (13.27%) had slight deterioration, and 4 patients (3.54%) had obvious deterioration. The good prognosis rate was 60.18%, and the poor prognosis rate was 39.82%. In single factor analysis, the related factors for poor prognosis included age>52 years (χ 2=15.07, P<0.001), educational level in secondary schools and below (χ 2=8.58, P=0.003), physical labor (χ 2=4.66, P=0.031), hypertension (χ 2 = 16.38, P<0.001), diabetes mellitus (χ 2=6.06, P=0.011), dyskinesia caused by first-generation antipsychotics, calcium channel blocker or flupentixol/melitracen tablets ( P<0.001), and the duration of dyskinesia more than 2 years (χ 2 =7.05, P=0.008). Multivariate Logistic regression analysis showed that the independent risk factors for poor prognosis of tardive dyskinesia included hypertension ( OR=3.60, 95% CI 1.17-11.05, P=0.025) and dyskinesia caused by first-generation antipsychotics, calcium channel blocker or flupentixol/melitracen tablets ( OR=3.14, 95% CI 1.21-8.16, P=0.019). Conclusions:Most patients with tardive dyskinesia have a good prognosis. Hypertension and dyskinesia caused by first-generation antipsychotics, calcium channel blocker or flupentixol/melitracen tablets are independent risk factors for poor prognosis.
