    EVALUATION OF AMINO ACID PROFILE IN SERUM OF PATIENTS WITH COVID-19 FOR PROVIDING A NEW TREATMENT STRATEGY
    (Soc Medical Biochemists Serbia, 2022) Ozturkl, Ali; Bayraktar, Nihayet; Bayraktar, Mustafa; Ibrahim, Bashar; Bozok, Taylan; Ceylan, Mehmet Resat
    BackgroundAmino acids have an important role in metabolism and may affect COVID-19-related outcomes. In our study, the amino acid serum level of hospitalized COVID19 patients was evaluated to determine a new treatment strategy.MethodsThe amino acid profile covering 43 amino acids in 68 subjects, comprising 30 (14 men and 16 women) controls and 38 (16 men and 22 women) COVID-19 patients, were examined. The amino acid profiles of the participants were screened by LC-MS/MS.ResultsCompared with the control group, serum levels of 27 amino acids increased in the patient group. Alpha-aminopimelic acid, sarcosine, and hydroxyproline amino acids were considerably higher in the control group than in the patient group (p<0.0001). There was no notable difference among control group and the case group for 13 amino acids (p >= 0.05). A significant positive correlation was seen among the control and the patient groups in the mean amino acid values (r=0.937; p<0.0001).ConclusionsThese results postulated a clear picture on the serum levels of amino acid in the COVID-19 patients. Serum amino acids measured in hospitalized COVID-19 patients can explain the patient's metabolic status during the disease.

    Evaluation of the Relationship Between Aquaporin-1, Hepcidin, Zinc, Copper, and Iron Levels and Oxidative Stress in the Serum of Critically Ill Patients with COVID-19
    (Springernature, 2022) Bayraktar, Nihayet; Bayraktar, Mustafa; Ozturk, Ali; Ibrahim, Bashar
    Our study aims to determine the relationship between hepcidin, aquaporin (AQP-1), copper (Cu), zinc (Zn), iron (Fe) levels, and oxidative stress in the sera of seriously ill COVID-19 patients with invasive mechanical ventilation. Ninety persons with and without COVID-19 were taken up and separated into two groups. The first group included seriously COVID-19 inpatients having endotracheal intubation in the intensive care unit (n = 45). The second group included individuals who had negative PCR tests and had no chronic disease (the healthy control group n = 45). AQP-1, hepcidin, Zn, Cu, Fe, total antioxidant status (TAS), and total oxidant status (TOS) were studied in the sera of both groups, and the relations of these levels with oxidative stress were determined. When the COVID-19 patient and the control groups were compared, all studied parameters were found to be statistically significant (p < 0.01). Total oxidant status (TOS), oxidative stress index (OSI), and AQP-1, hepcidin, and Cu levels were increased in patients with COVID-19 compared to healthy people. Serum TAC, Zn, and Fe levels were found to be lower in the patient group than in the control group. Significant correlations were detected between the studied parameters in COVID-19 patients. Results indicated that oxidative stress may play an important role in viral infection due to SARS-CoV-2. We think that oxidative stress parameters as well as some trace elements at the onset of COVID-19 disease will provide a better triage in terms of disease severity.

    What is the novel coronavirus disease 2019 (COVID-19) that paralyze the world?
    (Lippincott Williams & Wilkins, 2020) Ozturk, Ali; Abdulmajed, Olkar; Ibrahim, Bashar
    The outbreak of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 infection has recently spread worldwide was declared a pandemic on March 11. The most common symptoms of COVID-19 disease are fever, fatigue, and dry cough. Some patients may experience pain and aches, nasal congestion, cold, sore throat or diarrhea. These symptoms are usually mild and begin gradually. Currently, the source of the virus is still unknown. However, all available evidence indicates that the origin of this virus is a natural animal and that it is not a manufactured virus. The virus spreads faster than its two ancestors the severe acute respiratory syndrome coronavirus and Middle East Respiratory Syndrome Coronavirus. The effects of COVID-19 disease on people are that the elderly and people with preexisting medical conditions (such as hypertension, heart disease, and diabetes) have more severe symptoms than others. Some potential vaccines and drugs specifically needed to treat this disease are being investigated and are being tested by clinical trials. Copyright (C) 2020 Wolters Kluwer Health, Inc.
