About this study

Official title: Orthostatic Dysregulation and Associated Gastrointestinal Dysfunction in Parkinson's Disease - Evolution A Monocentric Study to Investigate the Development of Symptoms of Autonomic Dysregulation in Parkinson's Disease

Symptoms of blood pressure dysregulation, impaired swallowing and digestion are common amongst parkinson patients. The overall aim of this study is to examine blood pressure regulation and esophageal motility and gastric emptying in Parkinson's disease (PD) patients.

The investigators hypothesize that - compared to age-matched controls - PD patients display an altered regulation of blood pressure, altered gastroesophageal motility, and delayed gastric emptying. These symptoms occur already early in the disease process, but aggravate with progression of the disease.

The investigators will perform a 7-day blood pressure measurement, measurement of central blood pressure and pulse wave velocity, assessment of pulse variability, Schellong tests to assess orthostatic function, high resolution manometry assessments during swallowing acts, and a 13C-sodium octanoate breath test to assess gastric emptying, in 18 PD patients (9 each Hoehn\&Yahr stages 1,2) and 12 age- and gender-matched healthy controls. Results will be interpreted in relation to the severity of PD motor symptoms.

The investigators anticipate that blood pressure dysregulation and gastroesophageal motility disturbances will be present only in PD subjects, but not in matched controls without neurological disorders and without any extrapyramidal motor signs. Furthermore, the investigators expect to find an association between motor impairment and the severity of these autonomic symptoms, however, that according to the Braak staging, subtle disturbances must already be present in the early stages of PD.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. orthostatic hypotension

    drop of systolic (≥20mmHg) or diastolic (≥10mmHg) blood pressure upon Schellong test

    Measured: during study visit

Secondary outcomes (7)
  1. delayed gastric emptying

    statistical difference in mean gastric emptying assessed via octanoate breath test

    Measured: during study visit

  2. long term blood pressure

    mean 7d systolic, diastolic, mean arterial blood pressure and heart rate recordings

    Measured: during 7d after study visit at home

  3. heart rate variability

    difference in heart rate variability or spectral analysis of heart rate variability?

    Measured: during study visit

  4. arterial stiffening

    difference in pulse wave velocity and augmentation index calculation from applanation tonometry recordings?

    Measured: during study visit

  5. oesophageal motility

    high-density manometry to measure aspects of oesophageal motility

    Measured: during study visit

  6. subjective symptoms of gastrointestinal and cardiovascular dysfunction

    validated questionnaires: Fraser, 2007, p14133; Stanghellini, 1996, p14183; Revicki, 2003, p13823; Kaufmann, 2012, p13817; }

    Measured: during study visit

  7. Clinical assessment

    UPDRS part III and MoCA score (Nasreddine, 2005, p14186)

    Measured: during study visit

Questions about this trial

What is this clinical trial studying?

An observational study of Parkinson's Disease - Autonomic Dysregulation, run by University of Zurich at 1 site in Switzerland.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 0 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 30 Sep 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Switzerland. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

orthostatic hypotension (time frame: during study visit). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01518751, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Sep 2015.
