ABSTRACT
BACKGROUND: According to the results of the ESSE-RF study, the frequency of obesity in the population reached 29.7%. Obesity is one of the main risk factors for the development of cardiovascular diseases. Features of the course of COVID-19 in patients with obesity is a very urgent problem. AIM: The aim of the study was a comparative investigation of clinical and laboratory-instrumental parameters in AH patients with or without obesity who had COVID-19 associated pneumonia, to identify the role of obesity as a potential predictor of post-COVID cardiovascular complications 3 months after discharge from the hospital. MATERIALS AND METHODS: Materials and methods. The study included 174 patients with COVID-19-associated pneumonia. Group 1 included 78 patients with AH without obesity, group 2 - 96 patients with AH and obesity. All patients were tested with a blood sample at the time of admission and 3 months after discharge from the hospital. We assessed parameters of general blood test, biochemistry, hemostasis, inflammation biomarkers - concentration of C-reactive protein (CRP), highly sensitive CRP (hs-CRP), homocysteine, IL-6, etc. All patients initially underwent computed tomography of the chest. In both groups, 24-hour blood pressure monitoring was performed using BPLaB device, according to the standard protocol;echocardiography using an expert class ultrasound diagnostic system Vivid S70. The study is registered with the Clinical Trials.gov database Identifier: NCT04501822. RESULT(S): Results. The biomarker that significantly distinguished the both groups of patients, as well as subgroups according to the degree of obesity was the concentration of maxCRP and hs-CRP, which was significantly higher in group 2. In addition, the registered maximum values of MPO, NT-proBNP, IL-1,6, TNA-alpha and NRL parameters in group 2 of patients with 2-3 degrees of obesity, may indicate the highest probability of developing delayed adverse cardiovascular complications in this group of patients. Mean systolic blood pressure, variability of systolic and diastolic blood pressure, and heart rate at night were significantly higher in AH patients with obesity. Numerous correlations of obesity with laboratory and instrumental parameters have been registered, which may indicate an increased likelihood of delayed unwanted cardiovascular complications in this particular group of patients. Multiple regression showed that obesity is an independent predictor of an increase in LDH, hs-CRP and right atrium. CONCLUSION(S): Dynamic control of the studied parameters in patients with AH and OB registered an increased concentration of CRP at the initial stage and 3 months after treatment, with a general trend towards a decrease in the increased initial structural parameters of ECHO CG. The logistic regression method showed that the presence of OB in patients with AH is an independent factor causing increased levels of immune inflammation (CRP), a marker of tissue destruction (LDH), and load on the right atrium.Copyright © Endocrinology Research Centre, 2022.
ABSTRACT
OBJECTIVE: The aim: To examine the diagnostic possibilities of determining the level of cystatin C in the blood serum in order to ascertain the functional status of the kidneys in patients with type 2 diabetes (those who recovered from COVID-19 infection) depending on the presence or absence of non-alcoholic fatty liver disease (further - NAFLD) and malnutrition. PATIENTS AND METHODS: Materials and methods: We investigated 18 patients with type 2 DM, who were included in the first group of the patients examined;group 2 consisted of 20 patients with type 2 DM and non-alcoholic fatty liver disease (NAFLD), namely with non-alcoholic steatohepatitis;and group 3 of the patients examined consisted of 30 patients with type 2 DM and obesity. RESULTS: Results: Renal damage in patients with metabolically associated diseases in the background of respiratory disease due to COVID-19 infection was also indicated by changes in urine test indicators, and namely - proteinuria and erythrocyturia, leukocyturia in urine sediment. The examination of cystatin C (Cys C) level indicates its statistically significant increase in patients of all examined groups, with the highest levels established in group 3 patients (with its increase up to 2.58 +/- 0.11 mg/L, compared with the norm of 0.75 +/- 0.04 mg/L in the control group - p < 0.01). The examination of GFR by calculation, where the Cys C index in serum was used, revealed a significant decrease in this parameter in all the examined groups of patients. At the same time, the maximum values were found in group 1 patients (65.7 +/- 1.4 ml/min per 1.73 m2 of the body surface), and the minimum values - in group 3 patients (48.3 +/- 2.7 ml/min per 1.73 m2 of the body surface). CONCLUSION: Conclusions: An increase in serum cystatin C levels was determined in type 2 diabetes patients, with the lowest level in group 1 patients (1.24 +/- 0.07 mg/L - p < 0.05), and the highest level in patients suffering from type 2 diabetes combined with NAFLD and obesity (2.58 +/- 0.11 mg/L - p < 0.01). A moderate to severe course of COVID-19 infection in patients with type 2 diabetes as well as with its combination with NAFLD and obesity contributes to the development of renal functional disorders in these patients. Moreover, an increase in serum Cys C levels is a more sensitive and earlier marker of renal damage development in comorbid pathology.
