Study Examines Immune Responses in Patients With Kidney Failure After COVID-19 Vaccination

In the multicenter study, the researchers discovered a postponed and insufficient antibody reaction and a blunted cellular immune action to vaccination in clients on hemodialysis. Responses were significantly more powerful with the mRNA-1273 vaccine than with the BNT162b2 vaccine (in both people with kidney failure and those with regular kidney function).
In addition, patients on hemodialysis who had a previous COVID-19 infection, did not take immunosuppressive drugs, had higher serum albumin levels and lymphocyte counts, had actually formerly reacted to liver disease B vaccination, and were on dialysis for only a short quantity of time had greater antibody and cellular immune reactions.
” We think that a high-dose vaccine may be a legitimate strategy to enhance SARS-CoV-2 vaccine efficiency in hemodialysis patients. The most vulnerable clients– those who are using immunosuppressive drugs, have a low serum albumin, a low lymphocyte count, are liver disease B vaccine non-responders, or have a high dialysis vintage– may be good prospects for a 3rd vaccine dosage,” said Dr. De Vriese.

Individuals with kidney failure who were on dialysis had a postponed and insufficient antibody reaction and a blunted cellular immune action following COVID-19 vaccination, compared with individuals with normal kidney function.
Immune actions were substantially more powerful with the Moderna mRNA-1273 vaccine than with the PfizerBioNTech BNT162b2 vaccine. A variety of other characteristics likewise forecasted the strength of patients immune reactions following vaccination.

Death rates from COVID-19 are especially high in individuals with kidney failure who are on dialysis, making SARS-CoV-2 vaccination in this population a high priority. A recent research study compared the immune actions of patients with and without kidney failure following immunization with different COVID-19 vaccines. The findings, which are released in JASN, may help improve vaccination methods in vulnerable patients.
People on dialysis normally have an impaired reaction to vaccination. To much better understand the predictors and dynamics of their antibody and cellular immune reactions to various SARS-CoV-2 vaccines, a group led by An S. De Vriese, MD, PhD (AZ Sint-Jan Brugge, in Belgium) prospectively evaluated responses at 4 or 5 weeks and once again at 8 or 9 weeks after immunization with the Pfizer-BioNTech (BNT162b2) and Moderna (mRNA-1273) mRNA vaccines in 543 patients on hemodialysis and 75 individuals with regular kidney function.

A current research study compared the immune actions of clients with and without kidney failure following immunization with different COVID-19 vaccines. In the multicenter study, the scientists found a delayed and insufficient antibody response and a blunted cellular immune response to vaccination in clients on hemodialysis. Actions were substantially more powerful with the mRNA-1273 vaccine than with the BNT162b2 vaccine (in both individuals with kidney failure and those with typical kidney function).

Outcomes may assist improve vaccination methods in susceptible clients.
