- Primary Outcome Measures
Name Time Method Microbiome Richness in Fecal Samples as Indicated by the Number of Taxonomies per Participant month 9 Any untoward medical occurrence after fecal microbiota transplantation (FMT) 9 months after treatments starts Microbiome Diversity in Fecal Samples as Indicated by the Shannon Diversity Index month 9 The Shannon diversity index is used to characterize species diversity in a community. Shannon's index accounts for both abundance and evenness of the species present. A high index value would represent a diverse and equally distributed community, and lower values represent a less diverse community. A value of 0 would represent a community with just one species. Typical values are generally between 1.5 and 3.5.
- Secondary Outcome Measures
Name Time Method Change in Sense of Smell as assessed by the University of Pennsylvania Smell Identification Test (UPSIT) baseline, 9 months The UPSIT is a comprehensive 40-item self-administered olfactory test that provides an absolute indication of smell loss (anosmia; mild, moderate or severe microsomia). The range of scores is 0 to 40, and a higher score indicates better olfaction
Motor function as characterized by Unified Parkinson's Disease Rating Scale (UPDRS) Motor Score 9 months UPDRS is a disability and impairment scale for PD progression and consists of 4 sections; I: evaluation of mentation, behavior, and mood (13 questions) II: evaluation of activities of daily living including speech, swallowing, handwriting, dressing, hygiene, falling, salivating, turning in bed, walking, and cutting food (13 questions) III: motor examination (33 scores based on 18 questions with right, left or other body distributions scores) IV: motor complications (6 questions)
All items have 5 response options: 0 = normal, 1 = slight (symptoms/ signs with sufficiently low frequency or intensity to cause no impact on function), 2 = mild (symptoms/ signs of frequency or intensity sufficient to cause a modest impact on function, 3 = moderate (symptoms/ signs sufficiently frequent or intense to impact considerably, but not prevent function), 4 = severe (symptoms/ signs that prevent function).
Motor Score ranges from 0 to 156, with higher scores indicating a worse outcome.Quality of Life as assessed by the Parkinson Disease Non-Motor Symptoms (PD NMS) Questionnaire 9 months The range of scores is 0 to 30. A score of under 10 is mild, 10-20 moderate and over 20 severe.
Change in number of bowel movements per day Baseline, 2 weeks The 2 week data point will be the average of bowel movements per day over the two weeks after initiation of treatment.
Motor function as characterized by Unified Parkinson's Disease Rating Scale (UPDRS) Total Score 9 months UPDRS is a disability and impairment scale for PD progression and consists of 4 sections; I: evaluation of mentation, behavior, and mood (13 questions) II: evaluation of activities of daily living including speech, swallowing, handwriting, dressing, hygiene, falling, salivating, turning in bed, walking, and cutting food (13 questions) III: motor examination (33 scores based on 18 questions with right, left or other body distributions scores) IV: motor complications (6 questions)
All items have 5 response options: 0 = normal, 1 = slight (symptoms/ signs with sufficiently low frequency or intensity to cause no impact on function), 2 = mild (symptoms/ signs of frequency or intensity sufficient to cause a modest impact on function, 3 = moderate (symptoms/ signs sufficiently frequent or intense to impact considerably, but not prevent function), 4 = severe (symptoms/ signs that prevent function).
Total Score ranges from 0 to 260, with higher scores indicating a worse outcome.Number of participants with an increase in flora diversity in fecal samples 9 months after treatments starts Cognitive domains characterized by using Montreal Cognitive Assessment 9 months MoCA is a rapid screening instrument for mild cognitive dysfunction. It assess different cognitive domains: attention and concentration, executive functions, memory, language, visuo-constructional skills, conceptual thinking, calculations, and orientation. The total score ranges from 0 to 30; a score of 26 or above is considered normal. MoCA will be performed at the enrollment for baseline and the clinic visit on 9 month for study endpoint assessment, and early termination visit (if applicable).
Qualify of life as assessed by the Parkinson's disease Questionnaire (PDQ-39) 9 months The Parkinson's disease Questionnaire (PDQ-39) is a 39 questions self-completed questionnaire that comprises 8 domains: mobility (10 items), activities of daily living (6 items), emotional well-being (6 items), stigma (4 items), social support (3 items), cognition (4 items), communication (3 items) and bodily discomfort (3 items). All items are assumed to impact QoL and must be answered to compute scores for each dimension. Questions are answered based on experiences from the preceding month using a 5-point ordinal scoring system: 0 = never, 1 = occasionally, 2 = sometimes, 3 = often, 4 = always. Overall score ranges from 0 = never have difficulty to 100 = always have difficulty. For each of the 8 domains, the domain score is the sum of scores in the domain divided by the maximum possible score of all items in the domain, multiplied by 100. The overall score is the sum of all 8 domain scores divided by 8.
Anxiety as assessed by the Parkinson Anxiety Scale (PAS) 9 months The Parkinson Anxiety Scale (PAS) is an anxiety measure scale for use in PD patients. This is a 12-item observer or patient-rated scale with three subscales, for persistent and episodic anxiety, and avoidance behavior. Items are scored on a 5-point Likert scale, with '0' meaning 'not or never' and '4' meaning 'severe or almost always'. Total score ranges from 0 to 48, with higher scores indicating worse outcomes.
Parkinson's disease symptoms as assessed by the Modified Hoehn and Yahr Scale 9 months Modified H\&Y scale will be used as a staging instrument to monitor progression of PD's symptoms. It defines broad categories of motor function in PD starting at Stage 0: no signs of disease to the highest stage 5: wheelchair bound or bedridden unless aided.
Number of participants who changed required PD symptomatic therapy after treatment 9 months after treatment Number of participants with worsening of PD symptoms or other potential microbial-mediated disorders 9 months after treatment Depression as assessed by the Geriatric Depression Scale Short form (GDS-SF) 9 months The Geriatric Depression Scale Short form (GDS-SF) is 15-item screening tool that is used to identify depression in older adults.The total score is 0 to 15, with a score of 5 or greater suggesting depression.
Change in gastric emptying time (GET) as assessed by the Smart Pill® (SP) Wireless pH/pressure recording capsule baseline, 13 weeks Smart Pill will be used to assess gastrointestinal dysmotility in PD patients before and after 12- week treatment. Smart Pill will be administered first during the run-In period clinic visit and again at Week 13 clinic visit following the completion of 12-week treatment.
