| Abstrakt: | Introduction: Coronavirus disease 2019 (COVID-19) has become a pandemic in late 2019. Its clinical presentation varies from asymptomatic infection to severe respiratory failure. Infection control strategies to minimize the risk of transmission of COVID-19 in end-stage renal disease (ESRD) patients receiving in-center hemodialysis (HD) have been implemented. Development of humoral response to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in adult patients with ESRD receiving HD has not been sufficiently reported. Methods: A total of 179 asymptomatic HD patients undergoing regular HD were screened for COVID-19 infection. Infection with SARS-CoV-2 was confirmed through a real-time reverse transcription polymerase chain reaction assay of nasopharyngeal swab specimens. They were classified into positive and negative groups according to the results of PCR. Results: Of the 179 asymptomatic patients, we found that 23 patients (12.8%) were positive for COVID-19. Their mean age was 45.61 ± 13.38 years. There was a significant difference between both groups regarding C-reactive protein, lymphocytes, and platelet counts (P < 0.001). Also, TAT (thrombin--antithrombin complex) and D-dimer levels were significantly increased among the positive group (11.47 ± 1.51 vs. 7.53 ± 1.64 mcq/L, P < 0.001; 1171.52 ± 267.6 vs. 542.76 ± 107.06 ng/mL, P < 0.001, respectively). Conclusion: Asymptomatic SARS-CoV-2 infection is detected in HD patients. They carry the risk of hypercoagulability complications. We need more strict infection control measures and proactive diagnosis to limit the spread of the infection and lethal thromboembolic complications. [ABSTRACT FROM AUTHOR] |
