早期帕金森病患者健康相关生活质量

目的 研究中国早期帕金森病(PD)患者健康相关生活质量(health related quality of life,HR-QOL)的特点;探讨运动症状和非运动症状对早期PD患者HR-QOL的影响.方法 在全国范围内共筛选出391例早期PD患者入组.采用统一帕金森病评分表(UPDRS)和Hoehn-Yahr评价运动症状,采用流行病学研究中心编制的抑郁量表(CES-D)、匹兹堡睡眠质量指数(PSQI)、疲劳量表(FSS)、阿尔茨海默病评定量表的认知部分(ADAS-Cog)和便秘量表分别对抑郁、睡眠障碍、疲劳、认知功能和便秘等非运动症状进行评价;采用36条目简化医疗结局调查问卷(SF-36)评价HR-QOL.比较PD患者与同龄健康老年人SF-36分值的差异.采用逐步多元线性回归分析深入探讨各种运动及非运动症状变量对HR-QOL的影响.结果 早期PD患者除SF-36躯体疼痛维度外,其余各维度分值较同龄健康老年人均下降.UPDRS第3部分分值(23.8±11.8)、Hoehn-Yahr分期(2.0±0.7)和强直分值(4.4±3.1)仅能解释SF-36总分变化的18.9%(R2=0.189).CES-D、FSS和PSQI分值等非运动症状变量引入回归方程后,SF-36总分可被解释的部分由18.9%增加至61.7%(R2=0.617).并且,引入CES-D分值后,SF-36总分可被解释的部分增加了43.3%(R2=0.433).结论 PD症状严重影响早期患者的HR-QOL.运动症状对HR-QOL存在影响,但影响作用有限.抑郁、疲劳和睡眠障碍这3个非运动症状是导致早期PD患者HR-QOL恶化的主要原因.其中,抑郁症状是HR-QOL恶化的最强预测因素.临床上,应重视非运动症状,运动和非运动症状兼治,才能真正提高疗效显著改善患者的HR-QOL.

Health related quality of life in patients with early Parkinson' s disease

Objective To investigate the characteristics of health related quality of life(HR-QOL) in Chinese patients with early Parkinson' s disease(PD), to identify the motor and non-motor factors that are associated with a poorer quality of life in patients with early PD. Methods All 391 patients with early PD were identified in a clinical-based study. Motor functions were measured by Unified Parkinson' s Disease Rating Scale (UPDRS) and Hoehn-Yabr Scale. Non-motor variables were assessed by Center of Epidemiological Survey Depression Scale (CES-D) for depressive symptoms, Pittsburg Sleep Quality Index (PSQI) for sleep disturbance, Fatigue Severity Scale (FSS) for fatigue, Alzheimer' s Disease Assessment Scale-Cognitive Sections (ADAS-Cng) for cognitive function, and Constipation Severity Scale for constipation. HR-QOL was measured by SF-36. Motor and non-motor variables were collected at the baseline assessment of a clinical trial and determined during a structured interview and by clinical examination by movement disorder specialists. The results were compared with those in healthy elderly people. Multiple regression analyses were used to determine which variables were strongly associated with lower levels of quality of life. Results Patients with early PD had a lower score on all dimensions of SF-36, except bodily pain dimension. Motor factors, particular physical disability and disease severity, contributed to decreased HR-QOL, but to a lesser extent. The motor score of the UPDRS (23. 8±11.8), Hoehn-Yahr stage(2. 0± 0.7), together with the rigidity score (4.4 ± 3.1), only accounted for 18.9 % (R2=0. 189) of the variance of SF-36 total score. The variables that most strongly predicted a low total SF-36 score were non-motor factors, particularly depressive symptoms, sleep disorders and fatigue. When the CES-D, FSS, and PSQI score were included in the model, the R2 increased from 0. 189 to 0.617, indicating that 61.7% of the variance in HR-QOL could be explained if additional CES-D, FSS and PSQI scores were known. Depressive symptoms, as measured by CES-D, had an overwhelming impact on HR-QOL. When CES-D score was included, the R2 change was 0.433, which indicated that additional 43.3% of the variability in HR-QOL could be explained by adding depressive symptoms. Conclusions PD has a substantial impact on HR-QOL, even if in its early stage. Depressive symptoms, sleep disorders and fatigue correlated strongly with lower quality of life. Depressive symptoms appeared to be the strongest determinant of HR-QOL in early PD patients. Every effort should be made to recognize and treat these conditions, thus improving all aspects of PD and giving these patients as good a quality of life as possible.
