Status Completed

Clinical Trial Summary

Evaluation of the effects of the K10 probiotic mix in patients with degenerative neurological diseases (Parkinson and Alzheimer's) with a focus on cognitive, motor and psychiatric neurological evaluation. Single-centre, double-blind, placebo-controlled randomized clinical trial (RCT), Interventional Model: Parallel Assignment, phase III study. Two groups will be composed, with two arms each, 1 group composed of patients with Parkinson's and 1 group with patients with Alzheimer's, 52 patients in each group. The first arm of each group will receive placebo and the other arm of each group will receive the mix K10. In this study, researchers will conduct a randomized, placebo-controlled, phase III trial of a probiotic preparation (Probiotic K10) to evaluate its use as a viable treatment option for neurodegenerative disorders, including Parkinson's disease (PD) and Alzheimer's disease. of Alzheimer (AD). This formulation has been previously demonstrated to improve cognitive function, systemic inflammation, systemic oxidative stress in Alzheimer's patients. The main objective of this study is to compare its effect with placebo on cognitive status in individuals with AD and PD, the UPDRS total score in people with early PD and quality of life, and the measurement of caregiver burden in AD and PD. Participants will be randomly assigned to receive a placebo (an inactive substance) and a K10 probiotic (dose 2 ml/kg/day). They will be evaluated at baseline, 45 days and 90 days.

Clinical Trial Description

Change in urinary cortisol dosage Determination of cortisol levels can be used as an indirect measurement of emotional stress. Reduced levels of this hormone are related to reduced cardiovascular risk and reduced inflammatory damage. Baseline to T90 or the time of sufficient disability to study closure. All measurements will be taken at time zero (start of the survey), the next measurement in 45 days and the last measurement in 90 days. We will use the comparison of the data collected from each individual at time zero in comparison with their own results collected at the next times, using biostatistics to compare the results and, at the end of the primary result, we will perform the simple tabulation to count the values of each analyzed variable. Differences between measures of central tendency with pr < 0.05 will be considered statistically significant. When the central tendency values present a normal distribution in the statistical test, a parametric test will be used. In the case of comparison of 2 means, Student's t test will be used, for paired or independent samples. When the comparison includes more than 2 means, analysis of variance (ANOVA) will be used for 1 way (a single factor, e.g. treatment time) or 2 ways (two factors, for example treatment time and control group x treated group ). After verifying a significant difference in ANOVA, a post hoc protected t-test will then be applied to detect at which points in the analysis there are pairs with significant differences. When the analysis of the distribution (frequency) of the data shows a distribution that is not compatible with the Gaussian distribution, a corresponding non-parametric test will be used. Contingency tables 2 x 2 will also be used for later calculation of risk factors and to determine the significance through the X2 test. The software to be used will be Prism from Graphpad v. 9 ;
