Abstract:

AIM: To investigate the correlationship between intestinal symptoms (constipation), colon pathological changes, lipopolysaccharide(LPS)and Parkinson's disease(PD) so as to provide theoretical and experimental basis for the early detection of PD and its pathogenesis.  METHODS: 102 PD patients were randomly divided into three groups through constipation questionnaire and discriminant analysis. Multivariate logistic regression analysis was used to analyze the relationship between the types of constipation and age, course of disease as well as course of constipation. 6 PD patients with constipation in were performed colonoscopy, and the infiltration of lymphocytes in colonic mucosa was detected by immunohistochemistry. LPS of 78 PD patients (23 cases without constipation and 55 cases with constipation) were detected by dynamic turbidimetric limulus test. RESULTS: (1) Within the total 102 PD patients, 23 cases presented without constipation while 79 cases with constipation, among which the STC, Mixed, RED were 31 cases (39.24%), 33 cases (41.77%) and 15 cases (18.99%) , respectively. (2) The colon mucosa of 6 PD patients with constipation showed chronic inflammation and a large number of CD+4 cell infiltration.(3) There were 15 cases of PD patients with the amount of LPS more than 0.1 EU/mL, 29 cases 0.1 to 0.01 EU/mL, and 34 cases <0.01 EU/mL among the 78 cases of PD patients, and the increased LPS was related to the constipation of PD patients. CONCLUSION: Constipation, colonic mucosal inflammation, chronic low-grade inflammation-induced intestinal LPS are associated with the occurrence and development of PD.
