In our previous report on antineutrophil cytoplasm antibodies (ANCA)-associated vasculitides (AAV) during the current COVID-19 pandemic, we described our observation of both an incidence-shift with a post-lockdown clustering and an increased incidence rate of AAV diagnoses between February and August 2020 compared with previous years.1

In correspondence to our article, Hocevar et al report how COVID-19 pandemic affected management of patients with vasculitides at their centre. The in-depth analysis examined symptom duration (ie, time eclipsed to final diagnosis), disease activity/severity and seasonal changes of patients presenting with giant cell arteritis, and IgA vasculitis and AAV during 2020 and in the previous decade. No significant differences were found in incidence rates or indications for deferrals; that is, symptoms were experienced for a longer length of time before a diagnosis was made or a more severe presentation occurred.2

As the COVID-19 pandemic remains ongoing, six patients with AAV treated at …
