简要总结
It is known that COVID-19 has a more negative clinical course and causes higher degrees of morbidity and mortality in case of COVID-19 in diabetic patients. However, the contribution of COVID-19 to hyperglycemia and its effect on glycemic parameters are uncertain. However, it is important to investigate homocysteine and lipid profile levels, respectively, and free radical levels known to be effective in the development of cardiovascular disease and diabetes due to oxidative stress, which can provide information about the identification and diagnosis of cardiovascular complications in the COVID-19 pandemic. In addition, as the decrease in physical activity levels of individuals in the COVID-19 pandemic may cause possible secondary complications such as an increase in the risk of cardiovascular disease, determining the physical activity levels of individuals and encouraging them to physical activity is another important parameter to minimize the negative effects of the process. Patients who applied to Izmir Bakircay University Cigli Training and Research Hospital (Cigli Regional Education Hospital) and hospitalized in the COVID-19 service and healthy controls are planning to include in this study. Patients diagnosed with COVID-19 will be included in Group I (n: 20), patients diagnosed with both Type II Diabetes Mellitus and COVID-19 will be included in Group II (n: 20) and healthy controls will be included in Group III (n:20). Hemoglobin A1c levels, lipid profiles, homocysteine, free radical levels and physical activity levels will be compared between groups. In addition, the change in the relevant variables before and after COVID-19 treatment will be determined by in-group comparisons in Group I and Group II. This study, which has a prospective and randomized controlled research plan, is planned to be carried out between January and February 2021. Research data will be obtained from blood samples taken from participants. In addition, data on physical activity levels will be collected through a questionnaire. After analyzing the data obtained from the research with appropriate statistical methods, the data will be evaluated.
详细描述
The coronavirus disease 2019 (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) results in significantly higher morbidity and mortality in patients with concomitant diseases such as diabetes mellitus and hypertension.
Glycemic management is of much more interest for both diabetes and COVID-19 patients, as diabetes has been reported to be associated with the poor prognosis of COVID-19. There is evidence that better glycemic control in COVID-19 patients is closely related to improved clinical outcomes. However, whether COVID-19 contributes to hyperglycemia is confusing. It remains unclear regarding the impact of COVID-19 infection on glycemic parameters, including blood glucose and hemoglobin A1c (HbA1c).
Lipid profile assessment is an important tool that helps diagnose cardiovascular diseases. Therefore, the stability of the samples is crucial for the analysis of total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C) and triglycerides (TG).Stability is the ability of analyte concentrations to be minimally affected within an acceptable range over a period of time.
High plasma homocysteine levels significantly increase the incidence of vascular damage in both small and large vessels. Concentrations above the 90th percentile are associated with an increased risk of degenerative and atherosclerotic processes in the coronary, cerebral and peripheral circulatory systems. Although homocysteine is an effective cardiovascular risk biomarker and is critical for cardiovascular complications in hospitalized COVID-19 patients, studies on this parameter have not focused much on laboratory markers useful for clinical evaluation of COVID-19.
Free radicals are continuously formed at the active site of enzymes as intermediates in enzymatic reactions occurring during cell metabolism. Reactive oxygen species and reactive nitrogen, known as intermediates, sometimes leach from the active site of enzymes and accidentally interact with molecular oxygen and form free oxygen radicals.Lipids, proteins, enzymes, carbohydrates, and DNA can be damaged due to oxidative stress, random breaks and bonds in DNA chains may occur as a result of damage to membranes, damage to enzymes and structural proteins may result in cell death, and these phenomena may result in cancer, neurodegenerative and cardiovascular diseases, diabetes and It constitutes the molecular basis in the development of autoimmune disorders.

Change of the levels of Hemoglobin A1c and Lipid Profiles at baseline and discharge for Group I and Group II
时间窗: At baseline and immediately before the discharge
Hemoglobin A1c and lipid profiles will be determined by venous blood samples taken from the participants. Blood plasma Hemoglobin A1c levels will be analyzed using immunoturbidimetric method and Lipid Profiles including Total cholesterol, high density lipoprotein (HDL) cholesterol and Triglyceride levels will be analyzed by using colorimetric methods in Medical Biochemistry Laboratory. Very low-density lipoprotein (VLDL) cholesterol and low density lipoprotein (LDL) cholesterol will be calculated by the Friedewald formula. All these parameters will be studied on the Cobas Integra 800 biochemical analyzer (Roche Diagnostics, Gesellschaft mit beschränkter Haftung (GmbH), Mannheim, Germany).

The levels of Homocystein and Oxidative Stress Parameters for Group III
时间窗: At baseline
Homocystein levels will be studied by using Enzyme Chemiluminescence Immunoassay (ECLIA), and Oxidative Stress Parameters including Superoxide Dismutase (SOD), Malondialdehyde (MDA), Total Antioxidant Level (TAL) / Total Oxidant Level (TOL) will be studied by photometric method in Medical Biochemistry Laboratory.
Change of Physical Activity Level at baseline and discharge for Group I and Group II
时间窗: At baseline and immediately after the recovery
International Physical Activity Questionnaire-Short Form (IPAQ-SF) will be used to determine the level of physical activity for last 7 days. This questionnaire consists of 7 questions and provides information about sitting, walking, moderate activities and time spent on vigorous activities. The calculation of the total score includes the total duration and frequency of walking, moderate activity, and vigorous activity. The sitting score is calculated separately. In the evaluation of all activities, the criterion is that each activity should be done at least 10 minutes. The walking time will be multiplied by 3.3 MET (The metabolic equivalent of task) in the calculation of the walking score. In the calculation, 4 METs for moderate activity and 8 METs for vigorous activity will be taken. Physical activity levels will categorize as inactivity (\<600 MET-min/week), low physical activity (600-3000 MET-min/week) and adequate physical activity (\>3000 MET-min/week) minutes/week).
