Association of the COVID-19 pandemic with increased adherence among prevalent hemodialysis patients.

BACKGROUND: During the COVID-19 pandemic, there has been a reduction in emergency department visits and hospital admissions. We hypothesized that hemodialysis patients were decreasing their hospital visits and increasing their dialysis adherence during the COVID-19 pandemic. MATERIAL AND METHODS: This is a retrospective analysis of hemodialysis patients treated in the seven American Renal Associates (ARA) dialysis centers in the Dallas-Fort Worth metropolitan area. We conducted a "before-and-after" study using existing clinical data to examine patient adherence with hemodialysis between January 1 and March 14, 2020 (pre-COVID) and March 15 to May 18, 2020 (COVID) time periods. Data points included missed treatments, shortened treatments, post-dialysis weight, and hospital visits. Finally, we conducted an anonymous survey in which patients reported their hemodialysis adherence. RESULTS: Data analysis was performed on 556 patients. Significantly fewer patients missed a single treatment in the COVID vs. pre-COVID time periods (44.1 vs. 58.6%; p < 0.001). Significantly fewer patients finished their treatment with a post-dialysis weight more than 1 kg above their estimated dry weight in the COVID vs. pre-COVID time periods (31.7 vs. 38.9%, p = 0.01). Finally, there was a reduction in total hospital visits during the COVID vs. pre-COVID periods (12.6 vs. 19.4%; p = 0.002). The anonymous survey showed patients reporting increased adherence with hemodialysis and restriction of salt and water intake. CONCLUSION: The COVID time period was associated with increased adherence with hemodialysis and decreased hospital visits, and patients were conscious of these changes.

COVID-19-associated atypical hemolytic uremic syndrome and use of Eculizumab therapy.

There is a high incidence of acute kidney injury with COVID-19 infections. The etiologies of acute kidney injury could be ischemic acute tubular necrosis or a complex process of complement activation leading to thrombotic microangiopathy. We present a case of 32-year-old Hispanic male with a history of heart transplant, admitted with COVID-19 and atypical hemolytic uremic syndrome, which was successfully treated with Eculizumab.
