Antibody Response in Hemodialysis and Non-dialysis Patients Diagnosed With COVID-19.

A Comparison of Antibody Response Against SARS-CoV-2 in Hemodialysis and Non-dialysis Patients Diagnosed With COVID-19.

This is prospective cohort study aimed to compare antibody response against SARS-CoV-2 in dialysis patients and non-dialysis-dependent volunteers.

The research hypothesis is that dynamic of IgG antibodies against SARS-CoV-2 will differ in two groups.

To determine whether there is a statistically significant interaction between factors "group" and "time" on the titer of IgG antibodies against SARS-CoV-2, a two-way repeated measures ANOVA will be used.

In both groups level of IgG antibodies against SARS-CoV-2 will be measured at the Day 1 (10 weeks from the date of first symptoms), Weeks 8 and 16 from the Day 1.

Inclusion Criteria:

• Age 18 years or older
• SARS-CoV-2 infection within 10 weeks prior enrollment, confirmed by PCR or strongly suspected on computed tomography
• Providing informed consent

Exclusion Criteria:

• Refusal to provide informed consent
