Basic Information

• Recruitment Status: UNKNOWN
• Total Enrollment: 80 participants
• Study Classification: OBSERVATIONAL
• Study Start Date: 2021-01-18
• Study Completion Date: 2021-09-30

Brief Summary

The primary aim of our study is to understand the effects of Covid-19 disease on vascular inflammation and coagulation cascade, and secondarily, to investigate its utility in predicting disease prognosis by analyzing serum PAI-1 levels in patients with different severity. The study is planned as a prospective, cross-sectional study that will include patients admitted to Covid-19 services between January 18, 2021, and August 30, 2021. A total of 80 volunteers will be enrolled in the trial whose age, gender, and BMI are planned to be matched.The study will be conducted on four groups. Group 1 (n=20; with mild symptoms), Group 2 (n=20; with moderate symptoms), Group 3 (n=20; with severe symptoms) and Group 4 (n=20; Control group).

All participants who accepted the study will have their sociodemographic data, medical history, and vital signs (respiratory rate, saturation, temperature, and blood pressure values) recorded at the start of the study. The pulmonologist in the study will also classify the patient group's chest X-ray and chest tomography findings and the thymus gland dimensions. After all four groups of patients have given their consent for the study, a sample of 5cc blood will be obtained once for the PAI-1 analysis.

Detailed Description

The study is planned as a prospective, cross-sectional study that will include patients admitted to Covid-19 services between January 18, 2021, and August 30, 2021. A total of 80 volunteers will be enrolled in the trial whose age, gender, and BMI are planned to be matched. The study will be conducted on four groups.

Group 1 (n=20; with mild symptoms)

• Covid positive patients with mild symptoms who required to be hospitalized,
• Symptomatic (fever, cough, weakness, joint pain, etc.) new patients who apply to the Covid clinic for the first time,
• Patients with stable vital signs and/or SpO2 ≥92% in room air, no radiological signs of lung involvement or mild pneumonia,
• Patients who have not been started on steroid therapy and who have not yet received anticoagulant therapy.

Group 2 (n=20; with moderate symptoms)

• Patients who are positive for Covid 19 and admitted to the covid clinic for the first time;
• Radiologically moderate pneumonia findings and/or SpO2=88-92% in room air,
• Patients who have not been started antiviral, steroid, and anticoagulant treatment.

Group 3 (n=20; with severe symptoms)

• Patients who are currently hospitalized in the Covid clinic,
• Patients with radiological findings of severe pneumonia or ARDS and/or high FiO2 requirement due to respiratory failure.
• Patients of this group may have received antiviral, anticoagulant, and/or steroid and/or biologic agent treatment.

Group 4 (n=20; Control group)

• The control group will be composed of healthy adult individuals applying to adult allergy outpatient clinics on a voluntary basis.
• Patients who have not been previously diagnosed with Covid-19 and have not vaccinated against Covid-19,
• The control patients will be matched with the study groups according to age, gender, and BMI.

All participants who accepted the study will have their sociodemographic data, medical history, and vital signs (respiratory rate, saturation, temperature, and blood pressure values) recorded at the start of the study. The pulmonologist in the study will also classify the patient group's chest X-ray and chest tomography findings, as well as the thymus gland dimensions. After all four groups of patients have given their consent for the study, a sample of 5cc blood will be obtained once for the PAI-1analysis. The sample will be centrifuged for around 5 minutes at 3000 rpm before being frozen at -70 degrees. The blood sample will be dissolved under proper conditions after a sufficient number of participants has been reached. The researchers will provide the ELISA kits for the study, and laboratory services will be purchased from outside the hospital. Due to Covid-19 disease, white blood cell, neutrophil, lymphocyte, and platelet counts, liver enzymes (AST, ALT, LDH), sodium, total protein, albumin, aPTT, PTZ, INR, D-Dimer, and fibrinogen levels will be recorded in the patient case report form, as well as CRP, IL-6, and ferritin levels, which are routinely requested from patients during their hospitalization. No treatment other than the treatments specified in the Covid-19 guidelines of the Ministry of Health will never be applied to the patients.
