About this study

The purpose of this study is to characterize microvascular reactivity on the forearm muscle using non-invasive near-infrared spectroscopy in critically ill COVID-19 patients, and to correlate its alterations with 28-day mortality in ICU COVID-19 patients.

Read the detailed description

After giving consent to participate in the study, the subjects included in the study will undergo a 15-minute measurement of tissue oxygen saturation (StO2) measured non-invasively on the forearm by means of near-infrared spectroscopy (NIRS). Once a baseline stable StO2 value is obtained, a provocative test, consisting of a transient vascular occlusion, will be performed. The test will allow the obtention of a local metabolic rate, and a StO2 recovery rate after the ischemic stimulus. This StO2 recovery rate will be considered as a reflection of the endothelial health of the patient.

Patients will be studied as soon as possible after admission to the ICU, and followed-up until ICU discharge or death.

What participants receive

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

  • Vascular occlusion testDevice

    The ischemic challenge will consist in a standardized Vascular Occlusion Test (VOT), as previously described in the literature. Briefly, a blood pressure cuff will be placed proximal to the forearm, and rapidly inflated at 40 mmHg above systolic pressure, and kept inflated during three minutes. Then the cuff will be rapidly deflated. The resulting deoxygenation (DeO2) and reoxygenation (ReO2) slopes will be reported as change in O2 saturation over time.

Questions about this trial

What is this clinical trial studying?

An observational study of COVID-19 and Endothelial Function, run by Corporacion Parc Tauli at 8 sites in 4 countries.

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 4 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 1 Aug 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 8 sites in Spain, Brazil, United States, Mexico. 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?

Results are not available in the source record.

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

Contact Jaume Mesquida, MD, PhD (+34 937231010 ext. 21155, jmesquida@tauli.cat), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

28-day mortality (time frame: 28 days). 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 NCT04689477, 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 1 Aug 2022; AzTrials last refreshed its copy on 7 Nov 2026.
