The effect of COVID-19 on vascular elasticity and liver function in overweight patients.

Objective. To study the changes in the vascular wall, vascular age and metabolic parameters in polymorbid COVID-19 conva-lescents. Material and methods. The study included 62 patients with hypertension who reached the target blood pressure (BP) with dual an-tihypertensive therapy after severe and extremely severe COVID-19. The following examinations were performed: laboratory tests of metabolic parameters, assessment of changes in the vessel elasticity indices (pulse-wave velocity (PWV), augmentation index (AI), central systolic BP (cSBP), 24-hour BP monitoring, and non-invasive markers of liver fibrosis. Results. According to office BP measurements, after the coronavirus infection, an increase in systolic BP (SBP) by 29.6% and di-astolic BP (DBP) by 23.6%, as well as heart rate (HR) by 11.8% (p<0.05) was reported during regular antihypertensive therapy. In addition, 24-hour BP monitoring data indicated an increase in the average daily SBP, DBP, and heart rate. After the coronavirus infection, an increase in PWV by 35.4% (p<0.05), AI by 24.4% (p<0.05), cSBP by 22.1% were reported. Carbohydrate and lipid metabolism parameters deteriorated. A pronounced adverse effect of coronavirus infection on liver function was observed. The vascular age (according to the modified SCORE scale) increased by 6 years (p<0.05). Conclusion. Our study showed that patients after severe and extremely severe COVID-19 have a high risk of liver fibrosis, hypertension and lipid metabolism control worsening and accelerating vascular aging.Copyright © 2023, Media Sphera Publishing Group.

Immune Response to Vaccination against COVID-19 at Different Second-Dose Intervals and Their Associations with Metabolic Parameters.

Obesity and diabetes are associated with severe outcomes of coronavirus disease (COVID-19). Vaccines against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have been proven protective against infection and severe COVID-19. However, the immune response of metabolically burdened individuals to the vaccines remains unclear. Thus, we aimed to assess whether the metabolic status of individuals affects their humoral immune responses to the vaccination. Moreover, we evaluated whether the interval between the first two doses influenced antibody concentration. Sixty-seven individuals (21 males, 46 females) were vaccinated with the BNT162b2 mRNA COVID-19 vaccine. Fifty-four individuals were vaccinated with the second dose after 3 weeks and 13 after 5 weeks. We measured the antibody titers in all participants during the 19-week follow-up period. Patients diagnosed with COVID-19 were excluded. In the 5-week interval group, a significantly higher level of maximal antibody titers was observed. However, there were no differences in antibody concentrations after 19 weeks and no significant correlation between cardiometabolic factors and humoral response. The elongation of second-dose timing to 5 weeks leads to a higher acute antibody response but does not change long-term levels of antibody titers. Moreover, dysregulation of metabolic parameters does not lead to a diminished immune response to vaccination.

RETURN TO LIFE: A CASE OF THE LAZARUS PHENOMENON

SESSION TITLE: Shock and Sepsis in the ICU Case Posters SESSION TYPE: Case Report Posters PRESENTED ON: 10/19/2022 12:45 pm - 01:45 pm INTRODUCTION: The Lazarus Phenomenon, also known as auto-resuscitation, is a rare event where cessation of CPR results in a delayed return of spontaneous circulation (ROSC). The phenomenon was named after the story of Lazarus, who was restored to life four days after death. We present a case of a 78-year-old male who presented to the hospital for septic shock and had intra-hospital cardiac arrest with ROSC after cessation of CPR. CASE PRESENTATION: 78 year old male with a medical history of paroxysmal atrial fibrillation, stage IIIA NSCLC and COPD, presented for progressive dyspnea. He complains of feeling weak with loss of appetite and had a recent mechanical fall. Initial vital signs were temperature 96F, BP 141/78, HR 75 bpm, RR 18/min, SaO2 100% on 2LNC. Initial labs showed lactic acid 11.6, BUN 55, creatinine 3.7, CO2 9, anion gap 25, AST 2654, ALT 2120, ALP 159, total bilirubin 0.8, troponin <0.1, CK 399, INR 4.2, PTT 36, WBC 16.5, Hb 10.8, and plt 202. COVID-19 testing was negative. CXR demonstrated a retro-cardiac opacity consistent with previous diagnosis of lung cancer versus a dense consolidation. He was started on antibiotics for sepsis and admitted to the ICU for his metabolic status and shock liver. He remained hemodynamically stable for a few hours until a he had sudden onset of unresponsiveness with asystole. Code blue was called. Repeat labs demonstrated lactic acid 15.5, potassium 6.3, CO2 9. He underwent resuscitation for 32 minutes when compressions were stopped. Within 5 minutes post arrest, sinus activity was noted on the cardiac monitor. The patient had a radial pulse on evaluation. Manual blood pressure measurement was 119/71 with a HR of 99. Arterial blood gas after ROSC showed a pH 7.0, pCO2 68, pO2 273, HCO3 16, lactic acid 19. A few hours later, the patient rapidly de-compensated and underwent resuscitation for a second time. Efforts were deemed futile and the patient expired. DISCUSSION: The physiologic description of the Lazarus phenomenon is yet to be fully elucidated. Hypotheses include auto-PEEP due to rapid manual ventilation generating increased intrathoracic pressure and decreased venous return, delayed drug effect and stunned myocardium during active chest compressions (1). Once chest compressions and positive pressure ventilation via manual bag-mask stops, sudden decrease in intrathoracic pressure allows for sudden venous return and re-perfusion of cardiac tissue, resulting in ROSC in some cases. A recent literature review cited 65 published cases over the past 30 years with the most common rhythm being asystole (2). Most cases of auto-resuscitation occurred between 5-10 minutes post stopping of chest compressions (2). Mortality of these cases were 70% post resuscitation (2). CONCLUSIONS: It is important for clinicians to be aware of the Lazarus phenomenon post resuscitative efforts and to observe patients carefully post resuscitation.

Fast tracking and early on table extubation following living donor liver transplantation, can we expand the criteria?

Background: Traditionally, patients were kept intubated for 48 hours in the postoperative period. Living donor liver transplantation poses a different set of challenges. Most of the predictors mentioned in the literature were, low MELD, low BMI, and with stable comorbidities etc. for early extubation following living donor liver transplantation. We assessed the feasibility of fast tracking and early extubation in our patients, who were not fitting in those mentioned predictors in the literature. Methods: We present a case series of 6 patients who were fast tracked and extubated early, following living donor liver transplantation, out of 22 patients over the last 6 months. Results: All these patients were aged more than 45 yrs, with an average age of 55.8 yrs, average MELD score of 20.8, Child status C, some of our patients had cardio pulmonary comorbidities. patient 2, was COPD, post asymptomatic COVID, with CoRad score3 on HRCT, patient 5, was class 3 obese with no OSA, patient 6, had Hypertension, CAD- triple vessel disease, post CABG 7 yrs back, The intraoperative metabolic parameters like base excess and Lactates were showing good correction and all of them had very minimal inotropic support at the time of extubation, with Norepinephrine < 0.05mcg/kg/minutes. There was no post reperfusion hemodynamic instability or PRS in our patients, the average GRWR in our patients was 0.94, the mean anhepatic period, warm ischemia and cold ischemia times were pretty low. None of them had any significant postoperative complications. Conclusions: We propose, we can safely fast track and extubate early, following living donor liver transplantation with high MELD scores, and stable comorbidities. Further, large studies are needed to look for the feasibility of expanding the criteria for early extubation.

DERIVATION OF A RISK SCORE TO PREDICT SEVERE COVID-19 PNEUMONIA IN HOSPITALIZED PATIENTS WITH OVERWEIGHT OR OBESITY

Background Although a higher body mass index (BMI) has been reported to be associated with severe COVID-19 pneumonia (severe disease), it is unclear if metabolic status plays a role. Being metabolically unhealthy (MU) is defined as having either hypertension, hyperlipidemia, type 2 diabetes mellitus/pre-diabetes, or non-alcoholic fatty liver disease. We aimed to derive a risk score to predict severe disease in patients with obesity or overweight according to metabolic status. Methods A retrospective study was performed for patients hospitalized with COVID-19 pneumonia between March 2020 and August 2021 at a single tertiary center. Patients were excluded if they were immunocompromised or had a BMI < 25.0. Wilcoxon rank sum test or Fisher's Exact test were performed. Univariate logistic regression was performed followed by multivariate logistic regression to derive a risk score to predict severe disease. Variables with the highest p-values were sequentially removed until removal led to less than a 1-point reduction (improvement) in the Akaike information criterion. Accuracy of the model was calculated using bootstrap resampling estimates of the area under the receiver operating characteristic curve (AUROCC). Results 334 of 450 patients hospitalized with COVID-19 pneumonia (74.2%) were MU. Older age, higher BMI, being a former smoker, and having been vaccinated for SARS-CoV-2 were associated with being MU. There was no difference in treatments for COVID-19 pneumonia according to metabolic status. Patients who were MU had a higher death rate (10.5% vs. 2.6%) and longer total length of stay (median 6 vs. 5 days). Figure 1. On univariate analysis, age at admission, male gender, Asian race, hypertension, and type 2 diabetes mellitus were significant predictors of severe disease, whereas being MU was not, p=0.27. On multivariate logistic regression, older age, male gender, and Asian race were associated with having severe disease. Not being vaccinated was associated with a doubled odds of severe disease (OR 2.24, 95% CI: 1.07, 4.59). Figure 2. The AUROCC of the final model was 0.66 (95% CI: 0.60 to 0.71). The risk score at the lowest quintile had a 33.1% to 65.5% predicted risk and a 58.7% observed risk of severe disease, whereas at the highest quintile there was an 85.7% to 97.7% predicted risk and an 89.7% observed risk of severe disease in our cohort. Conclusion In this retrospective study of hospitalized patients with COVID-19 pneumonia, being MU was not a predictor of severe disease, even though mortality rate and total length of stay were higher in this group despite having higher rates of vaccination. Older age at admission, male gender, Asian race, and being unvaccinated were associated with severe disease. Using this risk score may help to predict severe disease in hospitalized patients with obesity or overweight. External validation is recommended (Table Presented)(Table Presented)

MACROPHAGES IN EPICARDIAL ADIPOSE TISSUE AND SERUM NT-proBNP IN PATIENTS WITH STABLE CORONARY ARTERY DISEASE

Coronary artery disease (CAD) is widely considered a chronic inflammatory disorder, and dysfunction of epicardial adipose tissue could be an important source of the inflammation. Amino-terminal fragment of pro-B-type natriuretic peptide (NT-proBNP) is a known marker of cardiovascular disorders of cardiac origin. Recent studies show that inflammatory stimuli may influence its secretion. Our purpose was to evaluate NT-proBNP serum concentration in relation to immune cell ratios in epicardial adipose tissue (EAT), and cytokine levels in the patients with stable CAD. Patients with stable CAD and heart failure classified into classes II-III, according to the New York Heart Association (NYHA) scale, scheduled for the coronary artery bypass graft (CABG) surgery, were recruited into the study (n = 10;59.5 (53.0-65.0) y. o.;50% males). The EAT and subcutaneous adipose tissue (SAT) specimens were harvested in the course of CABG surgery. Immunostaining with anti-CD68, anti-CD45, anti-IL-1β and anti-TNFα monoclonal antibodies was performed to evaluate cell composition by differential counts per ten fields (400 magnification). Fasting venous blood was obtained from patients before CABG. Blood was centrifuged at 1500g, aliquots were collected and stored frozen at -40 °С until final analysis. Concentrations of NT-proBNP, IL-1β, IL-6, IL-10, TNFα were determined in serum samples by enzyme-linked immunosorbent assay (ELISA). We have found increased production of IL-1β and TNFα cytokines in EAT compared to SAT. Concentrations of NT-proBNP exceeded 125 pg/ml in 4 patients, and correlations between the CD68+ macrophage counts in both EAT and SAT samples (rs = 0.762;p = 0.010 and rs = 0.835;p = 0.003, respectively). NT-proBNP levels showed positive relations with CD45+ leukocyte counts (rs = 0.799;p = 0.006), and with IL-1β+ cell numbers (rs = 0.705;p = 0.023) in EAT samples only. As for the serum biomarkers, NT-proBNP levels showed negative correlation with fasting glucose levels (rs = -0.684;p = 0.029), and positive correlation with serum IL-6 concentrations (rs = 0.891;p = 0.001). Increased serum concentrations of NT-proBNP in CAD patients correlate with accumulation of macrophages in EAT, which is associated with increased production of IL-1β in EAT and correlates with some metabolic parameters.

Vicious cycle between severity of childhood obesity and pandemic: Potential impact of metformin.

Introduction: COVID-19 is currently a global pandemic, and initial reports of identified COVID-19 lockdown and limitations can adversely affect childhood obesity and metabolic health. Studies conducted in recent years have shown that the rate of obesity in childhood increases with the changing lifestyle with the pandemic. However, there is insufficient data on how the situation changes and how metabolism is affected in those, who are already obese. The aim of this paper was to determine how the pandemic affects the current status, severity, and metabolic parameters of obese children. We also attempted to show potential effects of metformin therapy. Methods: The study was conducted with the participation of 101 patients with obesity (The mean age was 13.6 ± 2.2). The patients were evaluated using pre- and post-lockdown data with an interval of 6 months. The new classification system was used to determine the severity of obesity. All anthropometrics, metabolic parameters (Blood glucose, insulin, HbA1C, lipid profile), lifestyle, and comorbidities were evaluated by dividing the participants into various subgroups according to their obesity and metformin usage status. Results: Our data shows that weight, height, BMI, BMI-SD, and BMI percentiles all increased significantly, after the pandemic started. The severity of obesity increased statistically (overweight decreases and class 2 obesity increases, p = 0.001). No change was observed in metabolic parameters. Surprisingly, a significant increase was observed in insulin and HOMA-IR values in the group with-metformin. Discussion: Most studies about childhood obesity have only focused on obesity increases and pandemic relation. Our study showed that although there was no significant change in metabolic status at the end of a lockdown period, there was a serious increase in the severity of obesity. Metformin use had no effect on either obesity or metabolic parameters, and even an increase in insulin resistance indicators was observed.

Evaluation of functional training along with online nutritional education on autistic children's metabolic status during Covid-19 pandemic-A randomized clinical trial

Physical inactivity and poor dietary pattern are considered as health related challenges in ASD (ASD) which seems to be affected by Covid-19 pandemic. The purpose of this clinical trial was to investigate the effect of functional training along with online nutritional education on metabolic related biomarkers in children with ASD. 80 verified children with ASD (age=9.73 ± 1.29, weight=49.94 ± 2.08 kg, stature=146.08 ± 40 cm, BMI percentile= 64.88 ± 2.89, FM percentage+24.71 ± 1.48) were randomly divided into four groups including: (1) functional training, (2) online nutritional education, 3) training+ education and 4) control group. Pre-test was taken for metabolic related biomarkers and each experimental group received their interventions for 8 weeks. Post-test was taken at the end of 8 weeks. The results from this study, did not show significant changes for WHR (sig=0.06). Significant changes was indicated for FM (sig<0.001), TC(sig<0.001), TG (sig=0.006), HDL (sig<0.001), LDL (sig=0.001), HOMA (sig=0.04). In conclusion, functional training and online nutritional education can be considered as beneficial interventions for metabolic related biomarkers improvement in children with ASD during Covid-19 pandemic.

Molecular profile of oral fluid in new coronavirus infection.

Oral fluid is an alternative biological material that confirms correlations with blood parameters in various pathological conditions of the body. In order to find a non-invasive approach to stratification of patients with COVID-19 disease, molecular biomarkers of the oral fluid have been determined in patients with moderate coronavirus infection in comparison with clinically healthy individuals. It has been shown that proteomic, carbohydrate, macro- and microelement profiles of the oral fluid in coronavirus infection can be used for diagnostics. The features of protein metabolism were revealed: an increase in the content of total protein, urea; increased activity of enzymes aspartate aminotransferase, gamma glutamyl transpeptidase, creatine phosphokinase, alkaline phosphatase; changes in carbohydrate metabolism, which is expressed by an increase in glucose and lactate levels, an increase in lactate dehydrogenase activity, sodium, chloride, calcium, magnesium, iron content.

Glycemic control in children with T1D in Kuwait during the COVID-19 pandemic: Data on a convenient sample of Childhood-Onset Diabetes electronic Registry (CODeR)

Introduction: The COVID-19 pandemic brought forth distressing challenges in numerous countries including Kuwait. To minimize the spread of the virus, lockdowns were imposed through closure of schools and the enforcement of social distancing. T1D children may be critically impacted during this period due to these restrictions. To maintain efficient disease management and outcomes, virtual diabetes clinics were implemented. Objectives: This study aimed to evaluate glycemic control of T1D children and its association with demographic variables before and during the pandemic. Methods: A convenient sample of children and their parents were randomly selected from the Childhood-Onset Diabetes electronic Registry (CODeR). Patient demographics and diabetes history were obtained through phone calls and direct interviews. HbA1c results were recorded after reviewing medical charts of 12-month periods before and during the pandemic (Feb 24, 2019-Feb 23, 2020 vs Feb 24, 2020-Feb 24, 2021) and compared to evaluate glycemic control. Results: Forty-nine children with T1D (age 9.3±3.2 years, 44.9% males, diabetes duration 3.5±1.9 years) participated in the survey. Majority of patients were receiving multiple daily injection therapy (88.9%) compared to continuous subcutaneous insulin infusion therapy (11.1%). No significant changes in HbA1c results prior to and during the pandemic (10.01%±1.72 vs 9.66%±1.59, p>0.05) were observed. Gender, nationality and age did not affect glycemic variations during the two time periods. However, children with a shorter diabetes duration (<5 yrs) showed slightly improved HbA1c results during the pandemic (9.89%±1.71 vs 9.66%±1.68, p=0.04). Conclusions: Virtual diabetes clinics may have allowed patients frequent contact with their physicians and facilitates communication from home environments which resulted in insignificant improvement of metabolic status. These are preliminary findings on T1D children in Kuwait and future studies are necessary to evaluate glycemic outcomes prior to and during the pandemic.
