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.

Dialysis
Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...
