Characteristics of hemodialysis patient with critical COVID-19.

Introduction: The clinical course of hemodialysis patients with COVID-19 still remains unclear.

Methods: Thirty-four hemodialysis patients were retrospectively enrolled. Patients were divided according to disease severity, and clinical symptoms and laboratory data at admission were compared.

Results: The serum C-reactive protein (CRP) level, d-dimer level, and white blood cell (WBC) count were significantly higher in the group with critical disease than in the group with mild to severe disease (p = 0.005, p = 0.039, and p = 0.045). The serum CRP level exceeded 10 mg/dl within 7 days of clinical onset in all the cases with critical disease.

Conclusion: Hemodialysis patients with COVID-19 who have elevated serum CRP and d-dimer levels, and an elevated WBC count at admission and patients with serum CRP levels exceeding 10 mg/dl before day 7 after clinical onset should be carefully monitored for possible progression to critical disease.
