New Onset of Giant Cell Arteritis following ChAdOx1-S (Vaxevria®) Vaccine Administration

Abstract: We report a 78-year-old man presenting with persistent headaches in vertex and temporo-parietal area; fatigue, worsening after walking; jaw claudication; scotomas; pharyngodynia; and dry cough after the second dose of the SARS-CoV-2 vaccine (ChAdOx1-S) administration. Laboratory findings showed an elevated C-reactive protein level and FDG-CT PET showed evidence of active large vessel vasculitis with diffuse abnormal artery uptake. Under suspicion of vasculitis, a temporal arteries biopsy was performed; the his… Show more

“…One out of eight patients had no headache; however, PET-CT showed widespread FDG activity of the aortic branches, including cranial arteritis [33]. A temporal artery biopsy confirmed the diagnosis in five out of six patients [31,32,114,131,153]. The patient with a negative temporal artery biopsy had positive FDG activity on PET-CT. PET-CT confirmed LVV in 3/4 of patients [33,34,114]; however, one patient with negative PET-CT had a positive temporal artery biopsy [32].…”

“…All patients were diagnosed with giant-cell arteritis (GCA) [31][32][33][34]114,131,153], except one who was less than 50 years old [35]. Two patients had normal CRP.…”

“…One possibility is that the vaccine directly might cause pituitary impairment with cumulative effect. Autoimmune/inflammatory syndrome induced by vaccine adjuvants (ASIA syndrome), molecular mimicry, cross-reactivity or a pro-inflammatory state induced by vaccine components and subsequent activation of autoreactive B and T cells are speculated to be involved, as in Guillain-Barrè syndrome or optic neuritis (26)(27)(28).…”

“…During the SARS-CoV-2 pandemic, there have been several reports of GCA occurring after COVID-19 vaccination. We conducted a search of PubMed, and identified 13 cases of GCA reported in individuals following COVID-19 vaccination [12][13][14][15][16][17][18][19][20][21][22][23] (Table 2). Of the 14 cases, seven males and seven females, four cases of viral vector vaccine and ten cases of mRNA vaccine were observed.…”

“…Some reports have pointed out the potential role of certain viruses, such as cytomegalovirus or varicella zoster, as well as influenza vaccines, as triggers for GCA in predisposed individuals [9][10][11]. Furthermore, GCA that develops after COVID-19 vaccination has been reported [12][13][14][15][16][17][18][19][20][21][22][23], but its characteristics are not clear. Here, we present a case of GCA after COVID-19 vaccination with long-term follow-up and characterize GCA that developed after the COVID-19 vaccine.…”
