About this study

Official title: Longitudinal Interventional Study on Diaphragmatic Ultrasound in Facioscapulohumeral Dystrophy (FSHD) Patients

The goal of this prospective, longitudinal, single-center study is to describe respiratory function in patients affected by FSHD at baseline and after one year using both diaphragmatic ultrasound and pulmonary function test. The primary questions this study aims to answer are:

  1. How does respiratory function assessed by diaphragmatic ultrasound and pulmonary function tests change over 12 months in FSHD patients?
  2. How accurate is diaphragmatic ultrasound in detecting respiratory abnormalities in these patients compared to pulmonary function tests?
  3. What is the relationship between ultrasound and functional indices, and how do these indices correlate with demographic, clinical, and genetic data?

To achieve this, we will enroll a cohort of 34 patients affected by FSHD, and each of them will undergo a comprehensive neurological examination, body plethysmography, measurement of maximal inspiratory pressure (MIP) and maximal espiratory pressure (MEP) and nocturnal oximetry at baseline and after 12 months.

Read the detailed description

Respiratory involvement is a recognized but underexplored manifestation of facioscapulohumeral muscular dystrophy (FSHD), reported in up to half of affected individuals. It is primarily related to weakness of the diaphragm and abdominal muscles, as well as to possible thoracic deformities. Traditional spirometric tests may underestimate early or mild inspiratory abnormalities, limiting their sensitivity for clinical monitoring. Diaphragmatic ultrasound has recently emerged as a promising tool to assess both trophism and contractility of the diaphragm. To date, only one small cross-sectional study has applied this technique in FSHD, showing reduced diaphragmatic parameters compared to controls, and no longitudinal data are currently available.

This study aims to provide the first prospective evaluation of diaphragmatic ultrasound in a cohort of genetically confirmed FSHD patients, with assessments performed at baseline and after one year of follow-up. By combining diaphragmatic ultrasound with standardized pulmonary function tests, body plethysmography, and respiratory muscle strength measurements, the study will comprehensively characterize respiratory involvement in FSHD and evaluate the potential role of ultrasound-derived indices as sensitive biomarkers.

The study design allows for the correlation of ultrasound findings with clinical and demographic characteristics, including disease duration, genetic features, and severity scores, as well as with conventional pulmonary outcomes. The longitudinal approach will clarify the ability of ultrasound to detect early or progressive respiratory impairment and its potential to complement or surpass routine respiratory function tests.

Ultimately, this project seeks to establish diaphragmatic ultrasound as a feasible and reproducible tool for the monitoring of respiratory function in FSHD. The expected results may inform the development of improved clinical guidelines for respiratory surveillance and contribute to early identification of patients who may benefit from targeted interventions, such as respiratory physiotherapy or non-invasive ventilation.

What is being measured

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

  1. One-year evaluation of the ultrasound diaphragmatic trophism

    Diaphragmatic thickness (DT) after a normal expiration (basal-DT) and after a maximal inspiration (max-DT)

    Measured: At enrollement and one year -follow-up

  2. One-year evaluation of the ultrasound diaphragmatic contractility

    Diaphragmatic thickening after a maximal inspiration determined as the difference between max-DT and basal-DT

    Measured: At enrollement and one year -follow-up

  3. One-year evaluation of the ultrasound diaphragmatic contractility (as ratio)

    Diaphragmatic thickening after a maximal inspiration determined as the ratio of difference between max-DT and basal-DT to basal-DT

    Measured: At enrollement and one year -follow-up

  4. One-year evaluation of the ultrasound diaphragmatic excursion

    Diaphragmatic excursion after a maximal inspiration

    Measured: At enrollement and one year -follow-up

Questions about this trial

What is this clinical trial studying?

A study testing Diaphragmatic ultrasound and Pulmonary function test in people with FSHD1 and FSHD2, run by Fondazione Policlinico Universitario Agostino Gemelli IRCCS at 1 site in Italy.

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 3 inclusion and 1 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: looking for participants now, as of the sponsor's last update on 8 Sep 2025. 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 Italy. 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?

This study is still under way. Results are not available in the source record yet.

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

Contact Enzo Ricci (+390630157088, enzo.ricci@policlinicogemelli.it), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

One-year evaluation of the ultrasound diaphragmatic trophism (time frame: At enrollement and one year -follow-up). The study lists 4 primary outcomes in all. 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 8 Sep 2025.
