Serial SARS-CoV-2 Receptor-Binding Domain Antibody Responses in Patients Receiving Dialysis.

ABSTRACT:

Background

Assessing the evolution of SARS-CoV-2 immune response among patients receiving dialysis can define its durability in a highly clinically relevant context because patients receiving dialysis share the characteristics of persons most susceptible to SARS-CoV-2 infection.

Objective

To evaluate the persistence of SARS-CoV-2 receptor-binding domain (RBD) IgG in seroprevalent patients receiving dialysis.

Design

Prospective.

Setting

Nationwide sample from dialysis facilities.

Patients

2215 patients receiving dialysis who had evidence of SARS-CoV-2 infection as of July 2020.

Measurements

Remainder plasma from routine monthly laboratories was used to measure semiquantitative RBD IgG index value over 6 months.

Results

A total of 2063 (93%)
