Clinical Trial Summary

The necessity for early detection and hence improving the outcome of treatment of pneumonia is critical especially SARS-CoV-2 induced cases. This work was designed to evaluate the potential application of measuring circulating epigenetic markers namely, miR-744, miR-24, miR-124, miR-155, miR-19a, miR-122, miR-21, miR-223, let-7f, miR-146, miR-196, miR-136, P13-K, miR-9 expression, and DNA methylation profiling of the ACE2, TMPRSS2, PARP, HOX1 genes in Coronavirus disease 2019 (COVID-19) due to SARS-CoV-2 with/without pneumonia and severe acute respiratory syndrome (SARS) patients as an attempt to evaluate the potential benefits of these new circulating, prognostic, epigenetic markers for Turkish patients.


Description:

The objectives of this observational study are 1) To investigate why COVID-19 infection causes different biological behavioral patterns in individuals, 2) To determine the role of epigenetic mechanisms here to detect the difference between individuals, 3)To determine the effectiveness of this behavior model and mechanisms on clinical treatment and to ensure that the results obtained are a step for further treatment studies, 4) To evaluate whether the data obtained in MicroRNA analysis is a predictive marker on prognosis. Material and methods Study design This is an observational prospective cohort study. In the power analysis performed with the G * power 3.1 programs related to our study, the effect size for the lymphocyte percentage and C-reactive protein was found to be 0.57 (Effective Treatment of Severe COVID-19 Patients with Tocilizumab) (alpha probability of error = 0.05); in the sample width analysis, taking the power value 0.80, the total number of patients to be collected was 105 (105/3 = 35 for each group).

Patient's criteria This study was approved by the Clinical Research Ethics Committee (2011- CREC-40) at Bakırköy Dr.Sadi Konuk Training and Research Hospital and informed consent will be obtained from all patients according to the rules of the Declaration of Helsinki. Approval of the local ethical committee number is 2020/143 (2011-CREC-40). Patients enrolled in this study will be admitted to the Infectious Diseases and Clinical Microbiology Department and the Intensive Care Department from May 2020 to September 2020. Diagnosis of COVID 19 will be depending upon the presence of specific lesions in lungs confirmed by computed tomography (CT), and/or laboratory findings according to the Republic of Turkey Ministry of Health diagnostic criteria.

Inclusion criteria All patients between the ages of 18 and 65 included will suffer from COVID 19, and specific treatment should not yet be initiated. COVID 19 diagnosis of patients will be based on full medical history, thorough clinical examination, radiological imaging, laboratory assessment, and SARS-CoV-2 analysis by RT-PCR.

Exclusion criteria

1. People with chronic lung disease or previous AC surgery

2. People with immune deficiency or cancer patients

3. Patients receiving immunosuppressive therapy for autoimmune disease

4. People with neurological diseases affecting the respiratory muscles, such as hypotonia.

On the basis of the inclusion and exclusion criteria 105 patients subjects will be included in this study, divided into three groups; group I (n = 35) patients are mild, group II (n = 35) patients are moderate, and group III (n = 35) patients are severe and critical. Mild and moderate cases are usually defined as those without severe pneumonia or severe acute respiratory syndrome. Mild symptoms are low-grade fever (not more than 38 degrees celsius), dry cough, fatigue, sore throat, headache, the new loss of taste, and smell. Patients with normal or mild pneumonia findings of radiological imaging and blood lymphocyte count ≥800 / µl and serum CRP≤40 mg /l, ferritin ≤500ng/ml, D-Dimer ≤1000 ng/ml will be included in group I. Moderate symptoms are fever of about 38,5-39 degrees celsius, chills, deep cough, fatigue and body aches, muscle pain, the general feeling of being unwell. Patients with bilateral diffuse pneumonia findings of radiological imaging or blood lymphocyte count <800 / µl or serum CRP> 40 mg / l or ferritin> 500ng / ml or D-Dimer> 1000 ng / ml will be included in group II. Severe symptoms are all the common symptoms mentioned above along with shortness of breath, chest discomfort, confusion/unresponsiveness, bluish face/lips, possible gastrointestinal issues, like diarrhea or nausea. Patients with ICU (intensive care unit) admission criteria, such as confusion or tachycardia (> 125 / min) or respiratory distress or tachypnea (> 22 / min) or hypotension <90/60 mmHg or SPO2 <93%will be included in group III. Also, patients with the central nervous system and heart involvement will be directly included in the severe case group.

Specimen collection and handling About 10 ml of peripheral venous blood will be collected under strict aseptic conditions by clean venipuncture using vacuum blood collection tubes and will be distributed as 3 ml in EDTA tubes for complete blood count and DNA extraction, 3 ml in another sterile special RNA protective tube (stored at −80 °C) for miRNA extraction. In addition, 4 ml in a plane tube will be allowed to clot at the room temperature and then will be centrifuged at 3000 rpm for 10 minutes and the collected serum will be stored at −80°C to be used for analyzing cytokine, and other specific tests.On the 7th day of treatment, second samples will be taken under the same conditions and finally, on the 21st day, third samples will be taken.

Laboratory investigations RNA Extraction was done according to the miRNeasy Serum/Plasma Advanced Kit (cat. no. 217204) https:// www.qiagen.com/
