ABSTRACT
Dialysis patients are compromised hosts;thus, they might become even more seriously ill in the case of infection with severe acute respiratory syndrome coronavirus 2 (SARS-COV-2). A man in his 50s under maintenance dialysis was accidentally a close contact of someone with SARS-COV-2 infection. Therefore, he received the PCR test for SARS-COV-2 three days a week at the time of his visit to our hospital for his hemodialysis session. He was admitted the day after the result of the PCR test was positive. This patient belongs to a high-risk group with severe illnesses, including the fact that he had not been vaccinated against SARS-COV-2. He received antibody cocktail therapy (casirivimab/imdevimab) on the day he was hospitalized. As a result, he escaped aggravation of COVID-19. This case suggests the important of early diagnosis and early treatment with this cocktail therapy for prevention of aggravation of COVID19 in high-risk hemodialysis patients.
