About this study
Official title: Incidence and Characteristics of Pulmonary Embolism in COVID-19 Patients Hospitalized for Acute Respiratory Syndrome
Multicentric case-control study that is aims at:
- evaluating the prevalence of pulmonary embolism among a large population of consecutive patients admitted for COVID-19 pneumonia into two large university hospitals in Paris, France: Groupe Hospitalier Paris Saint-Joseph (GHPSJ) and Hôpital Européen Georges Pompidou (HEGP)
- and identifying the characteristics associated with pulmonary embolism by using a nested case control study design within the patients who underwent either unenhanced computed tomograpghy (CT) or CT pulmonary angiogram (CTPA) evaluation.
Read the detailed description
In December 2019, China reported the first cluster of severe acute respiratory syndrome due to a new coronavirus (SARS-CoV-2). The disease rapidly spread into a global pandemic of public health emergency worldwide leading to more than 330.000 deaths (data from May 25th, 2020). We have, to date, no demonstration on the efficacy of any drug to cure or prevent severe evolution of the disease (COVID-19). The primary target of SARS-CoV-2 is the lung with frequent occurrence of acute respiratory distress syndrome (ARDS) justifying supportive care, including invasive mechanical ventilation (IMV). The characteristics of ARDS in COVID-19 patients appeared atypical due to the dissociation between initial well-conserved lung compliance and severe hypoxemia, attributed to pulmonary vasoregulation disruption and local thrombogenesis. Strikingly high D-dimers levels, caused by both inflammation storm and coagulation activation, have been early reported in COVID-19 patients and have been associated with increased mortality. A single observational study suggests that anticoagulation is associated with a decreased mortality in severe COVID-19 patients. These reports have led to several therapeutic propositions in terms of anticoagulant therapy from worldwide scientific societies (Khider et al JMV 2020). Publications recently reported thrombotic complications in series of severe COVID-19 patients admitted in ICU, but the frequency of pulmonary embolism (PE) in larger cohort of COVID-19 patients of any severity remains uncertain.
This cohort enrolled patients in whom PE is proven by CTPA and compared them into two subgroups of controls matched for age and sex in whom PE was either excluded or non suspected:
- COVID-19 patients with a negative CTPA and
- COVID-19 patients in whom only an unhenced CT was performed.

Questions about this trial
What is this clinical trial studying?
An observational study of Pulmonary Embolism and Covid-19, run by Fondation Hôpital Saint-Joseph at 1 site in France.
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 4 inclusion and 2 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 25 Jun 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 France. 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?
Impact of PE on COVID-19 patients (time frame: March 1st, 2020). 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 NCT04420312, which also lists 26 linked publications.
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 25 Jun 2020.
