About this study
Official title: Evaluation of Lung Doppler Signals (LDS) in Detecting Pulmonary Arterial Hypertension in Patients With Systemic Sclerosis (SSc)
Doppler signals can be recorded from the lung parenchyma by means of a pulsed Doppler ultrasound system incorporating a special signal processing package- the Transthoracic Parametric Doppler (TPD) (Echosense Ltd., Haifa, Israel). Systemic sclerosis patients often develop pulmonary vascular disease leading to pulmonary hypertension. The TPD system may provide important insight into pulmonary blood vessels characteristics by the LDS (Lung Doppler Signals) signals that are related to pulmonary hypertension. The TPD performance in detecting PAH in SSc patients will be assessed in the study.

Recording Doppler ultrasound noninvasively from the right chest wall
What is being measured
The primary outcome is the main question the study is designed to answer.
1. Number of SSc patients correctly identified with pulmonary hypertension severity in each of the 4 defined groups by RHC.
Analyze Doppler data of 4 SSc groups (according to pulmonary hypertension severity) resulting in typical features. The features will be implemented in a pre-determined diagnostic algorithm that will determine the overall statistical success of the method in comparison to RHC data.
Measured: 12 month

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Doppler signals can be recorded from the lung parenchyma by means of a pulsed Doppler ultrasound system incorporating a special signal processing package- the Transthoracic Parametric Doppler (TPD) (Echosense Ltd., Haifa, Israel). Systemic sclerosis patients often develop pulmonary vascular disease leading to pulmonary hypertension. The TPD system may provide important insight into pulmonary blood vessels characteristics by the LDS (Lung Doppler Signals) signals that are related to pulmonary hypertension. The TPD performance in detecting PAH in SSc patients will be assessed in the study.

Questions about this trial
What is this clinical trial studying?
A study testing Ultrasound radiation in people with Systemic Sclerosis and Pulmonary Hypertension, run by Echosense Ltd..
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?

Is this clinical trial currently recruiting?
The record says: withdrawn, as of the sponsor's last update on 2 Dec 2015. Status can change between updates, so confirm with the study contact before making plans.
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 was withdrawn before enrolling participants, so there are no results.
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?
1. Number of SSc patients correctly identified with pulmonary hypertension severity in each of the 4 defined groups by RHC. (time frame: 12 month). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 2 Dec 2015; AzTrials last refreshed its copy on 6 Nov 2026.
