Category: Parkinson's Disease: Pathophysiology
Objective: To find any relationship between cardiovascular risk factors such as diabetes mellitus, hypertension or both and worse state in patient with PD measured with the MDS-UPDRS I, II and IV subscales (with permission from the MDS).
Background: Parkinson disease (PD) is the second more prevalent neurodegenerative disease and cardiovascular risk factors have been associated to its development or progression, like diabetes mellitus and hypertension.
Method: We propose a study model trying to find any relation between these risk factors and worse state in patient with PD measured with the MDS-UPDRS I, II and IV subscales (with permission from the MDS).
We used I, II and IV subscales since they reflect closer reality to the state of the disease with respect to QOL, complications and ADL performance independent of on or off state.
Results: We included 36 patients with Parkinson’s Disease 18 years-old and older, without functional surgery for PD. Patients signed out an informed consent to participate in our research. A survey was applied with demographical variables including the MDS-UPDRS subscales I, II and III for each patient. For study purposes we divided patients into groups with or without DM, hypertension or either, to analyze data.
We found 41.7% (15) females and 58.3% (21) males, with a mean of age of 59.22 ± 12.59, age of first symptom was 50.58 ±11.64 within 8.64 ± 4.73 years with diagnose of PD without statistical significance between patients stratified by gender or vascular risk factors (DM, hypertension, or any). We found 13.9% (5) patients with DM and 25% (9) patients with hypertension in our sample.
They showed marginal significative statistical difference with a higher score of the MDS-UPDRS-III for patients with PD and DM (P = 0.057).
Conclusion: In our study a confounder factor could be the known assotiaton to DM with cognitive and non-motor symptoms due to polyneuropathy icreasing the MDS-UPDRS-I score, however, mean time diagnosis with DM in our patients was less than 5 years and then not clinicaly strong to consider it as a confounder. In a post-hoc analysis the greater relation with worse MDS-UPDRS IV was with age of the patients and this variable needs to be consider for further studies.
