ABSTRACT

BACKGROUND: The recent outbreak of Coronavirus Disease 2019 (COVID-19) is a public health emergency of international concern. In China, Wuhan, Hubei Province was the epicenter. The disease is more severe in patients with high comorbidities and dialysis patients fall into this category.

METHODS: In this report, we reviewed the whole course of the epidemic emerged in the HD center of Wuhan NO.1 Hospital by 28 February 2020. We compared the differences on the epidemiological characteristics and clinical features between patients surviving from COVID-19 and patients who died.

RESULT: In this hospital, at time of the present report, 627 patients were on chronic hemodialysis and the prevalence of affected cases was 11.8% (74/627).The median age of the COVID-19-positive patients was 63 years (range 31-88), with an almost even gender distribution (females accounted for 54.4%).The most frequent presenting symptom was cough (41.9%), followed by fatigue (24.2%), fever (17.2%) and dyspnea (14.8%); 22.4% of the cases were and asymptomatic. Fourteen of the 74 patients died (19%), as for presenting symptoms, cough was more frequent in patients who died (P < 0.05). Surviving patients had higher levels of phosphate and albumin, and lower levels of C-reactive protein (CRP). Chest CT scan was positive in all cases, including in asymptomatic ones, and revealed in about three fourths of the cases bilateral (76.2%) lesions; in each lung lesions were multiple in about half of the cases of the cases (52.3%). After diagnosis, median time to death was 7 days in the 14 patients who died, with a range between 4 and 18 days.

CONCLUSION: This preliminary, single Center study identifies hemodialysis patients as a population at high risk of severe, and deadly COVID-19 infection. While classic baseline clinical conditions, including age, kidney disease and gender, are not significantly associated with survival in COVID-19 infected hemodialysis, our study also suggests a significant association between risk of and death, poor nutritional status and less than optimal metabolic balance.
