Study summary

The purpose of the study COVID-EP is to classify all the complications occurring after the diagnosis of pulmonary embolism in patients tested initially COVID-19 positive and negative by RT-PCR (on nasopharyngeal sample) during the peak of the pandemic in France (April 2020). The patients will be followed for 1 year in order to provide clinical and paraclinical data not yet published in the literature. In order to secondarily confirm the COVID-19 status of initially negative COVID-19 patients (by RT-PCR), a serology test will be performed. The collected complications will then be compared between each of the 3 following groups: [PCR-COVID 19-Neg \& Sero-COVID 19-Neg] versus [PCR-COVID 19-Neg \& Sero-COVID 19-Pos] versus [PCR-COVID 19-Pos].

Groups and cohorts

  • [PCR-COVID 19-Pos] group

    Having a microbiological diagnosis confirming COVID-19 infection (ie positive RT-PCR on nasopharyngeal swab) and/or clinical/CT signs

  • [PCR-COVID 19-Neg] group

    Having a microbiological diagnosis confirming the absence of COVID-19 infection (ie negative RT-PCR on nasopharyngeal swab) and absence of clinical /CT signs

    Diagnostic Test: Serology test for COVID-19

  • [PCR-COVID 19-Neg & Sero-COVID 19-Pos] group

    * Having a microbiological diagnosis confirming the absence of COVID-19 infection (ie negative RT-PCR on nasopharyngeal swab) and absence of clinical /CT signs * Having been tested positive in a serological test for COVID-19 at M3

  • [PCR-COVID 19-Neg & Sero-COVID 19-Neg] group

    * Having a microbiological diagnosis confirming the absence of COVID-19 infection (ie negative RT-PCR on nasopharyngeal swab) and absence of clinical /CT signs * Having been tested negative in a serological test for COVID-19 at M3

Interventions

  • Diagnostic testSerology test for COVID-19

    In order to secondarily confirm the COVID-19 status of initially negative COVID-19 patients (by RT-PCR), a serology test will be performed in two parts: 1. ELISA test 2. Rapid Diagnostic tests (only if ELISA test is positive)

What researchers measure

Primary outcomes

  1. % of patients for each group presenting the occurrence of PE complications defined by the occurrence of at least ONE of the following events up to 6 months after PE diagnosis.

    PE complications : * Chronic interstitial pathology, or * Recurrence of PE, or * Pulmonary hypertension, or * Death.

    Time frame: 6 months after PE diagnosis

Secondary outcomes

  1. % of patients for each group and subgroup presenting the occurrence of PE complications defined by the occurrence of at least ONE of the following events up to 12 months after PE diagnosis.

    PE complications : * Chronic interstitial pathology, or * Recurrence of PE, or * Pulmonary hypertension, or * Death.

    Time frame: 12 months after PE diagnosis

  2. % of patients in each group presenting the occurrence of each of the following events at each follow-up (3 months, 6 months and 12 months after PE diagnosis).

    PE complications : * Chronic interstitial pathology, or * Recurrence of PE, or * Pulmonary hypertension, or * Death.

    Time frame: 3, 6 and 12 months after PE diagnosis

  3. % of patients diagnosed COVID - at M0 by RT-PCR on nasopharyngeal swab and diagnosed COVID + by serology 3 months after PE diagnosis

    Time frame: 3 months after PE diagnosis

  4. Effectiveness of the different category of treatments used in all patients and in the groups: % of occurrence of PE complications for each categories of treatments

    Category of treatments: * Heparin + AVK * Heparin + DOAC PE complication : * Chronic interstitial pathology, or * Recurrence of PE, or * Pulmonary hypertension, or * Death.

    Time frame: 12 months after PE diagnosis

  5. Effectiveness of the different category of treatments used in all patients and in the groups: % of patients with occurrence of bleeding complications for each categories of treatments

    Category of treatments: * Heparin + AVK * Heparin + DOAC Bleeding complications: classification 1-2-3-5 according to BARC

    Time frame: 12 months after PE diagnosis

  6. Effectiveness of the different category of treatments used in all patients and in the groups: % of patients with no occurrence of complications for each categories of treatments

    Category of treatments: * Heparin + AVK * Heparin + DOAC

    Time frame: 12 months after PE diagnosis

  7. Effectiveness of the different category of treatments used in all patients and in the groups: duration of Heparin treatment (number of day)

    Category of treatments: * Heparin + AVK * Heparin + DOAC

    Time frame: 12 months after PE diagnosis
