Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This clinical study will create an evidence base for rehabilitation approach, which will be used for restoration of pulmonary ventilation and gas exchange, increase of tolerance to physical load reduced in patients who underwent COVID-19.

The aim of the present clinical study is to evaluate the effectiveness of medical rehabilitation of COVID-19 patients based on the study of individual physiological parameters of oxygen metabolism and reserve capabilities of the cardiovascular and respiratory systems.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

After an interview about the possibility of taking part in the study, the patient is presented with an informed consent form, explaining all the questions of interest. In the case of consent to participate in the study, the patient and the researcher fill out all the necessary fields of the two copies of the informed consent and sign it. If necessary, the researcher re-explains any information about the study. One copy of the informed consent remains with the patient, and the second copy is kept by the investigator, as required by Good Clinical Practice.

Once informed consent is obtained, an Individual Registration Card (IRC) is completed for the patient enrolled in the study. Completion of the IRC also continues until completion of the second phase of rehabilitation.

Pulmonary functional tests, cardiopulmonary stress testing (CPT) are performed on day 1 or 2 of inclusion of the patient in the rehabilitation program of "Federal Research Center for Fundamental and Translational Medicine" (FRC FTM) using MasterScreen Pneumo (Jaeger, Germany) and Oxycon Pro ergospirometry systems (Jaeger, Germany), in accordance with international standards. The indexes of external respiration are brought to BTPS conditions, and gas exchange - STPD. The protocol of stress testing is chosen individually, based on the proper values in accordance with the age, sex and anthropometric data of the patient. The study is conducted up to the individual maximum, followed by a recovery period. The anaerobic threshold is determined using the V-slope method. After peak load is reached, it is gradually reduced. Observation is continued until complete recovery of hemodynamic parameters, gas exchange, in case of adverse symptoms - until their disappearance. Repeated testing is performed after the rehabilitation program, before discharge from the FTC MTF.

Thoracic MSCT is performed on day 1-2 of inclusion of a patient into the rehabilitation program of the FRC FTM to assess the lesion of the bronchopulmonary system after COVID-19.

Questionnaires describing the severity of the underlying disease (mMRC respiratory impairment scale, BODE pulmonology risk scale, SMRT-CO respiratory support need scale), and SF-36 quality of life questionnaire are completed at study inclusion and after the rehabilitation program, before discharge from the FRC FTM.

Study Groups

Main

Patients 18 years of age and older who have undergone COVID-19 and who are scheduled for the second stage of rehabilitation at the Federal Research Center for Fundamental and Translational Medicine

Spirography and assessment of pulmonary diffusion capacity

Intervention Type DIAGNOSTIC_TEST

Using the Master Screen Body device you will be asked to take two series of breaths through a special tube for 2-3 minutes. Usually the procedure does not cause any discomfort

Cardiopulmonary stress test

Intervention Type DIAGNOSTIC_TEST

The exercise test is performed on a bicycle ergometer Oxycon Pro. Prior to the test, special sensors for recording the electrocardiogram, a sensor to determine blood saturation, and a cuff to measure blood pressure will be glued on the body. Breathing during the test takes place through a face mask with a built-in gas analyzer sensor. The stress test is conducted up to an individual maximum (according to the age, sex, height and weight of the patient), followed by a recovery period. There is some temporary discomfort associated with performing physical activity. Dyspnea, leg fatigue, and dizziness may occur. Observation continues until full recovery of hemodynamic and gas exchange parameters, in case of appearance of unfavorable symptoms - until their disappearance.

Computed tomography of the chest organs

Intervention Type DIAGNOSTIC_TEST

CT is a method of examination based on X-rays, but unlike conventional X-rays, it gives the most complete picture of the body structure, with less radiation.

Tomography usually does not cause any unpleasant feelings and is performed in a specialized department.

Heart echocardiography

Intervention Type DIAGNOSTIC_TEST

It's a specific method of ultrasound examination, which consists in examining the heart in real time and usually does not cause any unpleasant feelings

SF-36 Quality of Life Questionnaire

Intervention Type OTHER

Intervention Type DIAGNOSTIC_TEST

Age, sex, height. weight, body mass index (BMI)

Indicators characterizing the severity of the underlying disease
