Abstract

Background

Since December 2019, Coronavirus Disease 2019(COVID-19) occurred in wuhan, China, and outbreaked rapidly into a global pandemic. This current poses great challenges to hemodialysis (HD) patients.

Objective

To make a comprehensive evaluation and comparison between HD patients confirmed with COVID-19 and the general HD patients.

Methods

HD patients confirmed with COVID-19 in Wuhan No.5 Hospital were admitted as confirmed group from Jan 10 to Mar 15, 2020. And HD patients not infected in our dialysis center were chosen as control group. General characteristics, laboratory indicators were retrospectively collected, analyzed and compared.

Results

A total of 142 cases were admitted, including 43 cases in confirmed group and 99 in control group. Body mass index (BMI) was slightly lower in confirmed group than that in control group (P=0.011). The proportion of one or less underlying disease in confirmed group(51.16%) was higher than that in control group(14.14%)(P< 0.001), and the proportion of three or more underlying diseases in confirmed group(11.63%) was lower than that in control group(52.53%)(P< 0.001). Patients in confirmed group exhibited significantly lower hemoglobin, lymphocyte count, and lymphocyte percentage, but higher neutrophil percentage, neutrophil-to-lymphocyte ratio (NLR), C-reactive protein, aspartate transaminase, and alkaline phosphatase. There was no significant difference in age, gender, dialysis age, primary disease, the using of ACEI/ARB, platelet-to-lymphocyte ratio (PLR), and other indicators between the two groups.

Conclusions

Faced with Severe Acute Respiratory Syndrome-CoV-2 (SARS-CoV-2), HD patients with lower BMI and hemoglobin were more susceptible to be infected, which might be related to malnutrition. Once confirmed with COVID-19, HD patients expressed obviously dis-regulated of inflammation and immune.
