Association of cystatin C levels with H&Y scale and duration of pakinson's disease / 中国医师杂志

ABSTRACT

Objective To investigate the levels of cystatin C (CC) with the H&Y scale and duration of Pakinson's disease(PD)patients.Methods The study consists of 432 PD patients and 513 control subjects.PD patients were divided into 3 subgroups according to their H&Y scale.The levels of CC and Scr were measured.The statistics analysis was used to evaluate their associations.Results In PD and control groups, CC concentrations were significantly different (P ＜ 0.05), and Scr concentrations in two study groups were not significantly different(P ＞ 0.05).PD in each subgroup, CC concentrations in the medium group were significantly higher than the early and control groups, and CC in the late group was significantly higher than the other two subgroups.Rank correlation analysis and comparison of CC concentration and duration and H&Y score showed that CC concentration was positively correlated with the duration of PD(r =0.209, P ＜0.01), and that CC concentration and H&Y score were significantly positively correlated (r =0.618, P ＜0.01).Conclusions There was a certain correlation between CC levels and PD, and CC levels of PD patients were significantly higher.There was no significant increased CC in the initial stages of the disease, perhaps CC was not necessary cause of the onset of PD.However, the level of CC with H&Y stage and duration were positively correlated, perhaps CC may be involved in the process of disease progression, because high level of CC may increase PD patient's condition.
