ABSTRACT

Cytokine storm is recognized as one of the factors contributing to organ failures and mortality in patients with COVID-19. Due to chronic inflammation, COVID-19 patients with diabetes mellitus (DM) or renal disease (RD) have more severe symptoms and higher mortality. However, the factors that contribute to severe outcomes of COVID-19 patients with DM and RD have received little attention. In an effort to investigate potential treatments for COVID-19, recent research has focused on the immunomodulation functions of mesenchymal stem cells (MSCs). In this study, the correlation between DM and RD and the severity of COVID-19 was examined by a combined approach with a meta-analysis and experimental research. The results of a systematic review and meta-analysis suggested that the odd of mortality in patients with both DM and RD was increased in comparison to those with a single comorbidity. In addition, in the experimental research, the data showed that high glucose and uremic toxins contributed to the induction of cytokine storm in human lung adenocarcinoma epithelial cells (Calu-3 cells) in response to SARS-CoV Peptide Pools. Of note, the incorporation of Wharton's jelly MSC-derived extracellular vesicles (WJ-EVs) into SARS-CoV peptide-induced Calu-3 resulted in a significant decrease in nuclear NF-κB p65 and the downregulation of the cytokine storm under high concentrations of glucose and uremic toxins. This clearly suggests the potential for WJ-EVs to reduce cytokine storm reactions in patients with both chronic inflammation diseases and viral infection.

ABSTRACT

This study aimed to evaluate the onset characteristics of patients with uremia undergoing maintenance hemodialysis complicated with COVID-19, so as to improve the understanding, diagnosis, and treatment.26 cases were confirmed cases of COVID-19. Confirmed patients with COVID-19 undergoing maintenance hemodialysis in the blood purification center were recruited. The general data of patients, including age, sex, duration of dialysis, and basic diseases, were analyzed. The clinical features included fever, respiratory symptoms, and gastrointestinal symptoms. The items for laboratory tests included blood routine examination, liver function, C-reactive protein, procalcitonin, creatine kinase, creatine kinase-MB, markers of myocardial injury, B-type natriuretic peptide, D-dimer, and so forth. The imaging examinations referred mainly to computed tomography imaging findings of the lungs.Twenty-one cases were complicated with chronic basic diseases, such as hypertension or diabetes. In terms of clinical manifestations, 13 cases had fever, which was close to the number of cases without fever (13 cases). The respiratory symptoms included dry cough (19 cases), shortness of breath (9 cases), fatigue (11 cases), and so forth. Further, 15 patients had hypoxemia, indicating more severe patients. Sore throat (2 cases) was not significant, and a few patients reported gastrointestinal symptoms (3 cases). The results of blood routine examination showed decreased absolute lymphocyte count (0.7 ±â€Š0.4 × 10∼9/L), lower hemoglobin level (105.2 ±â€Š20 g/L), and normal absolute neutrophil count 4.2 (3.0, 5.9) × 10∼9/L. Of the inflammatory indexes, procalcitonin was 0.69 (0.24, 2.73) ng/mL; C reactive protein was 17.2 (5.2, 181.6) mg/L, which was higher than normal. Blood biochemistry revealed lower albumin level (38.0 ±â€Š4.0 g/L) and higher troponin 0.11(0.035, 6.658) ng/mL and myoglobin levels (538.5 ±â€Š240.5 ng/mL), suggesting myocardial injury.The patients with uremia and confirmed COVID-19 undergoing maintenance hemodialysis are more common in males. Although the proportion of fever patients is 50%, the proportion of hypoxemia patients is high (58%). With poor cardiac function. They were prone to respiratory failure complicated with heart failure. According to the onset characteristics of this population, early diagnosis and treatment could help reduce the risk of developing a critical illness and control the spread of the COVID-19 epidemic.
