Trial summary

Exercise training improves walking capacity and regional perfusion in patients with Intermittent Claudication (IC). Endothelial Progenitor Cells (EPCs) and Endothelial Microparticles (EMPs) could play an important role in this process, promoting the healing of the diseased endothelium. Read more about this study

About this study

Official title: Effects of Home-based Combined Aerobic and Resistance Training on Walking Capacity, Circulating Endothelial Progenitor Cells AND Endothelial Function in Patients With Intermittent Claudication

Exercise training improves walking capacity and regional perfusion in patients with Intermittent Claudication (IC). Endothelial Progenitor Cells (EPCs) and Endothelial Microparticles (EMPs) could play an important role in this process, promoting the healing of the diseased endothelium.

The investigators are going to measure EPCs and EMPs in a group of patients with IC and in a control group of healthy individuals before a treadmill test and 2, 24, and 48 hours after the test. Subsequently, a group of IC patients will be randomly assigned to perform a 12-week home-based exercise training program.

The investigators expect a significant increase of EMPs and EPCs after acute and chronic physical activity. We expect also a correlation between the increase of EMPs and EPCs and the improvement in walking capacity. Aim of the study is to demonstrate that acutely performed aerobic exercise could be able to promote the mobilization of EMPs and EPCs in patients with IC and that endothelial progenitor cells mobilization could play a pivotal role in exercise induced improvement of walking performance and endothelial function in subjects with IC.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • combined aerobic and resistance physical activityBehavioural

    Five training sessions weekly for 12 weeks are scheduled. Each session lasts 60 minutes divided into 45 minutes of aerobic workout and 15 minutes of circuit training. The aerobic workout consists of walking on a flat floor or on a slight uphill (maximum slope 3%): patients should walk until submaximal walking capacity (80% of their MWT) and rest as they would experience pain at the lower limbs; afterwards, they should start to walk again, once the pain was improved. Resistance training consists of calisthenics exercises focused on trunk and lower limbs muscles (bicycle, flutter kicks, squats, lunges, calf raises, wall sits and power press) with at least 3 repetitions for each exercise, interspersed by 30 seconds recovery. Duration of repetitions increases every 3 weeks.

What is being measured

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

  1. Endothelial Microparticles (EMPs)

    hematological parameter, cells particles released by activated endothelium, measured by cytofluorimetry

    Measured: week 0 - week 12

  2. Endothelial Progenitor Cells (EPCs)

    hematological parameter, immature bone-marrow derived cells which repair the damaged endothelium, measured by cytofluorimetry

    Measured: week 0 - week 12

  3. Maximum Walking Time

    functional parameter, maximum walking capacity for an individual with IC measured through a treadmill walking test

    Measured: week 0 - week 12

  4. Pain-free Walking Time

    maximum walking capacity for an individual with IC without experiencing pain measured through a treadmill walking test

    Measured: week 0 - week 12

  5. Flow-mediated Dilation

    ultrasonographic evaluation of endothelial function

    Measured: week 0 - week 12

Questions about this trial

What is this clinical trial studying?

A study testing combined aerobic and resistance physical activity in people with Peripheral Arterial Disease and Endothelial Dysfunction, run by University Of Perugia 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 2 inclusion and 7 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: status not confirmed, as of the sponsor's last update on 27 Mar 2020. 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. Some participants in this study may receive a placebo. 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?

Results are not available in the source record.

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?

Endothelial Microparticles (EMPs) (time frame: week 0 - week 12). The study lists 5 primary outcomes in all. 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 NCT04302571, 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 27 Mar 2020.
