Background

Sars-cov2 vaccination has altered the natural course of COVID-19. We aimed to explore the frequency of adverse events of vaccination in patients with glomerular diseases (GD) including the risk of GD relapse afterwards.

Methods

Patients were included if they had biopsy-proven GD and received at least one dose of sars-cov2 vaccine. Patients who ended up in ESKD prior to vaccination or received a GD diagnosis after vaccination were excluded. We recorded demographics, histopathological diagnosis, immunosuppressive regimens, GD outcome before and after vaccination, and adverse events associated with the vaccine. Outcomes of GD included remission, relapse, treatment resistance, ESKD, and death. The rate of GD relapse post vaccination was estimated among patients who had achieved remission.

Results

315 patients with biopsy-proven GD prior to sars-cov2 vaccination were included, with a mean age of 51(36-63) years at the time of diagnostic biopsy, of whom 142(45.1%) were males. Patients received a median of 3(3-4) vaccine doses. The median time from the diagnostic kidney biopsy to the 1^st vaccine dose was 48.9(19.8-106.2) months. Among 255 patients with known GD status at vaccination, 139 (44.1%) were on immunosuppressive therapy, 224(87.8%) were on remission and 31(12.2%) were still active. 66(21.0%) patients reported systemic side effects (fever, arthralgias, myalgias) and 122(38.7%) local side effects (pain, swelling, itching, edema) associated with the vaccination. Renal function and 24-hour proteinuria remained stable after vaccination. Among patients in GD remission at vaccination, 23(9.0%) experienced a relapse during a follow up time of 18.2(15.5-20.1) months. Of those, 8 (7.8%) were on immunosuppression and 15 (18.1%) were not (p=0.058). The mean time to GD relapse following vaccination was 2.5(1.2-6.4) months.

Conclusion

According to the findings from this cohort, vaccination against sars-cov2 appears safe for patients with GD, with no significant impact in renal function or the probability for relapse.
