About this study

Official title: Long-term Follow-up Findings of Inpatients for COVID-19 Pneumonia Related to Lung Functions, Radiology and Exercise Capacity

Coronavirus disease 2019 (COVID-19) is a respiratory tract infection caused by a newly emergent coronavirus (SARS-CoV-2) that can progress to severe multiorgan disease requiring hospitalization. The medium and long-term impact in survivors of COVID-19 on lung function, imaging by thoracic CT, exercise capacity, and health-related quality of life and the relation of these parameters remains to be determined.

Read the detailed description

Aim: To evaluate medium to late (visit 1: 6-12 months after hospital discharge) effects of COVID-19 on lung function, exercise capacity, thoracic CT findings, symptoms and HRQoL in patients with confirmed diagnosis of SARS-CoV-2 infection and the relation between these parameters.

Material and methods: Prospective cohort of subjects with laboratory and/or thoracic CT confirmed COVID-19 who were treated as inpatients. Participants will perform spirometry, lung diffusion capacity of carbon monoxide, 6-minute walk test (6MWT) and cardiopulmonary exercise testing (CPET) after 6-12 months (Visit 1) of COVID-19. Clinical, laboratory and chest image data during the COVID-19 hospitalization will be obtained from medical records.

The minimum sample size was estimated as 37 participants.

What is being measured

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

  1. Forced vital capacity (FVC)

    in ml

    Measured: at 6-12 months after discharge

  2. Lung diffusion capacity for carbon monoxide (DLCO)

    DLCO (%predicted); DLCO/alveolar volume- DLCO/VA (%predicted)

    Measured: at 6-12 months after discharge

  3. 6-minute walk test distance

    m

    Measured: at 6-12 months after discharge

  4. Short-form 36 questionnaire (SF-36)

    scores range between 0 and 100 with higher scores indicating a better HRQoL

    Measured: at 6-12 months after discharge

  5. Oxygen uptake at peak exercise

    from incremental Cardiopulmonary exercise test (% of predicted)

    Measured: at 6-12 months after discharge

  6. Minute-ventilation/carbon dioxide output during exercise

    from incremental Cardiopulmonary exercise test (L/L)

    Measured: at 6-12 months after discharge

  7. Dyspnea during exercise

    from incremental Cardiopulmonary exercise test (measured with 10-point categorical Borg scale

    Measured: at 6-12 months after discharge

  8. Thoracic CT findings

    lung parenchymal abnormalities as percentage of occupied lung

    Measured: in the first week of pneumonia and at 6-12 months after discharge

  9. Forced expiratory volume in 1 second

    in ml and %predicted

    Measured: at 6-12 months after discharge

  10. FEV1/FVC ratio

    in %

    Measured: at 6-12 months after discharge

  11. Forced vital capacity %predicted (FVC%)

    in %

    Measured: at 6-12 months after discharge

Secondary outcomes (7)
  1. Signs and symptoms

    Recorded separately as present or absent) mortality (recorded as present or absent)

    Measured: in the first week of pneumonia and at 6-12 months after discharge

  2. Time to hospital discharge

    in days

    Measured: in hospital

  3. ICU discharge

    in days

    Measured: in hospital

  4. Weaning from intubation

    in days

    Measured: in the period of intensive care

  5. Weaning from supplemental oxygen

    in days

    Measured: in hospital

  6. Weaning from noninvasive mechanical ventilation

    in days

    Measured: in hospital

  7. Mortality

    recorded as present or absent

    Measured: in hospital and at 6-12 months after discharge

Questions about this trial

What is this clinical trial studying?

An observational study of Covid19, run by Koc University Hospital at 1 site in Turkey (Türkiye).

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 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: finished, as of the sponsor's last update on 16 May 2024. 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 Turkey (Türkiye). 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?

Forced vital capacity (FVC) (time frame: at 6-12 months after discharge). The study lists 11 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 16 May 2024.
