Clinical characteristics of 31 hemodialysis patients with 2019 novel coronavirus: a retrospective study.

ABSTRACT

AIM: Novel coronavirus pneumonia (COVID-19) has become pandemic. It brings serious threat to hemodialysis (HD) patients. Therefore, we carried out a study on the clinical characteristics of HD patients with COVID-19. METHODS: We retrospectively analyzed the data of 31 HD patients with COVID-19. The clinical features of patients include epidemiology, clinical symptoms, laboratory and imaging test, treatment and prognosis. RESULTS: 61.3% were severe, and 38.7% were mild. 83.9% had a close contact history with COVID-19 patients. The average age was 62.3 years comprising of 58.1% men and 41.9% women. Ninety percent had chronic diseases except ESRD. Clinical symptoms include cough (85%), fever (43%), and shortness of breath (48.4%), etc. Complications included ARDS (25.8%), AHF (22.6%), and septic shock (16.1%), etc. 64.5% of patients had remission, and 35.5% of patients had no remission with 6.5% deaths. Compared with the baseline before infection, HD patients with COVID-19 had lower lymphocytes, albumin and glucose, and higher D-dimer, albumin, phosphorus, lactate dehydrogenase, and CRP. There was no significant correlation between the neutrophils/lymphocytes ratio and the severity of the disease. CONCLUSIONS: Compared with the reported general population, the HD patients are susceptible to COVID-19 infection, especially older men and those with other underlying diseases. Moreover, HD patients have more severe infection and inflammation with less symptoms and worse outcome. COVID-19 infection can cause dialysis patients lower immunity, stronger inflammation, malnutrition, and internal environment disorder. Neutrophils/lymphocytes ratio does not reflect the severity of the HD patients with COVID-19.
