Defining a PD-specific Breath Fingerprint of Underlying Inflammatory and Neurodegenerative Processes

14. Juni 2019 aktualisiert von: Malu Tansey, Emory University

Defining a Parkinson's Disease (PD) -Specific Breath Fingerprint of Underlying Inflammatory and Neurodegenerative Processes

The purpose of this study is to determine the potential for a Parkinson's Disease (PD) -specific breath signature as a non-invasive screening tool for identifying PD patients with inflammation, tracking the progression of disease, and responsiveness to various therapeutic interventions, in particular anti-inflammatory or immunomodulatory therapies. Neurological disorders include any disorder involving the brain or the nervous system, for example memory disorders, stroke, movement disorders and many other conditions.

The study will lay the foundation for future studies in which breath fingerprinting could be used as a screening technique. Investigators will also be looking at how the breath fingerprint correlates with inflammatory proteins in the blood.

Detaillierte Beschreibung

The purpose of this study is to determine the potential for a Parkinson's Disease (PD) -specific breath signature as a non-invasive screening tool for identifying PD patients with inflammation, tracking the progression of disease, and responsiveness to various therapeutic interventions, in particular anti-inflammatory or immunomodulatory therapies. Neurological disorders include any disorder involving the brain or the nervous system, for example memory disorders, stroke, movement disorders and many other conditions.

The study will lay the foundation for future studies in which breath fingerprinting could be used as a screening technique. Investigators will also be looking at how the breath fingerprint correlates with inflammatory proteins in the blood.

Investigators will determine how molecules in human breath can define a "breath signature" that can be associated with neurological disorders like Parkinson's disease. The long-term goal of this study is to use blood inflammatory marker relationships and Breath Analytical Approach to identify individuals at risk for development of neurologic disorders and to monitor the effects of immune interventions on the rate of disease progression.

The study team will recruit a total of 100 participants: 50 early stage (defined by a Hohn & Yahr Stages 1-2), non-smoking Parkinson's Disease patients from among the Emory Movement Disorders Clinic and 50 age and sex-matched healthy controls (HC). Investigators will recruit six to eight participants per month over an 18-month time period.

Kohorten und Interventionen

Gruppe / Kohorte
Intervention / Behandlung
Parkinson's Disease (PD)
Participant's with Parkinson's Disease will provide peripheral blood and breath samples. Participants will also be asked to complete a neurologic exam and questionnaires.
Sonstiges: Blood Sample Collection
Participants will have two to three tablespoons (30 cc) of peripheral blood drawn to test for inflammatory markers.
Sonstiges: Breath Sample Collection
Participants will be asked to breathe into the Breath Sampler containing a rapid passive volatile organic compounds (VOC) sampling device. A disposable mouthpiece is placed over a portion of the sampler where the participant placed his/her mouth. The mouthpiece will be disposed of after each use and a new one will be used for each participant. Prior to sample collection, the participant will be asked to rinse his/her mouth with water. Then the participant will breathe deeply into the sampler five times with breaths being five minutes apart to collect the alveolar breath.
Healthy Control
Age and gender-matched healthy controls will provide peripheral blood and breath samples. Participants will also be asked to complete a neurologic exam and questionnaires.
Sonstiges: Blood Sample Collection
Participants will have two to three tablespoons (30 cc) of peripheral blood drawn to test for inflammatory markers.
Sonstiges: Breath Sample Collection
Participants will be asked to breathe into the Breath Sampler containing a rapid passive volatile organic compounds (VOC) sampling device. A disposable mouthpiece is placed over a portion of the sampler where the participant placed his/her mouth. The mouthpiece will be disposed of after each use and a new one will be used for each participant. Prior to sample collection, the participant will be asked to rinse his/her mouth with water.

Was misst die Studie?

Primäre Ergebnismessungen

Ergebnis Maßnahme
Maßnahmenbeschreibung
Zeitfenster
Unified Parkinson's Disease Rating Scale Subscale II Score
Zeitfenster: Up to 15 minutes
The Unified Parkinson's Disease Rating Scale Subscale II is a measure of self-evaluation of the activities of daily life (ADLs) including speech, swallowing, handwriting, dressing, hygiene, falling, salivating, turning in bed, walking, and cutting food. Items are rated from 0 (normal) to 4 (severe). A higher total score indicates more severe disease.
Up to 15 minutes
Unified Parkinson's Disease Rating Scale Subscale III Score
Zeitfenster: Up to 15 minutes
The Unified Parkinson's Disease Rating Scale Subscale III is a clinician-scored monitored motor evaluation. Items are rated from 0 (normal) to 4 (severe). A higher total score indicates more severe disease.
Up to 15 minutes
Modified Hoehn and Yahr Scale Score
Zeitfenster: Up to 15 minutes
The Modified Hoehn and Yahr Scale is used to describe how the symptoms of Parkinson's disease progress. Stages of disease range from 1 to 5 where 5 is the most severe.
Up to 15 minutes
Overnight Questionnaire Score
Zeitfenster: Up to 15 minutes
The Overnight Questionnaire is completed by a person living with the participant with Parkinson's Disease. Questions refer to behaviors witnessed during sleep. Questions are answered on a scale from 1 (never) to 4 (always). A higher score indicates more symptoms of sleep disruption.
Up to 15 minutes
Beck's Depression Scale Score
Zeitfenster: Up to 15 minutes
The Beck's Depression Scale is a 21 one item scale used to describe how a participant has been feeling over the past two weeks. A total score between 0-21 indicates very low anxiety. A between 22-35 indicates moderate anxiety. A score that exceeds 36 indicates high anxiety.
Up to 15 minutes
Montreal Cognitive Assessment (MOCA) Score
Zeitfenster: Up to 10 minutes
The Montreal Cognitive Assessment (MOCA) is a rapid screening instrument for mild cognitive dysfunction. It assesses different cognitive domains: attention and concentration, executive functions, memory, language, visuoconstructional skills, conceptual thinking, calculations, and orientation. The total possible score is 30 points; a score of 26 or above is considered normal.
