Conclusion
We present a case of GPA with DAH, which developed shortly after
COVID-19 infection. COVID-19 and COVID-19- induced new-onset GPA share
many clinical and radiological features, making it challenging for
clinicians to distinguish between the two. Our study also provided some
clues about the diagnostic challenge of GPA induced by COVID-19. The
limited number of cases and retrospective evaluation are the limitations
of this review.The retrospective study based on this case could provide
useful information regarding the evaluation of clinical symptoms,
diagnostic methods, and management of this confusing condition.In
addition, the pathophysiology and mechanism of GPA induced by COVID-19
have not been fully elucidated and still need to be further studied.The
possibility of a common immune mechanism for the development of
vasculitis during SARS-CoV-2 infection and immunization warrants further
investigation, which could provide important information about the
pathogenesis of GPA and immune reactivity to COVID-19, and is crucial
for the diagnosis and treatment of GPA.
