‘Granulomatosis with polyangiitis after Pfizer vaccination’: a case report

Abstract: The advent of COVID-19, caused by the SARS-CoV-2 virus, has resulted in over 541 million cases with 6.32 million deaths worldwide as of June 2022. The devastating consequences of this global pandemic resulted in the expedited generation of mRNA-based vaccines such as the Pfizer-BioNTech and Moderna vaccines. Although the vaccines have been effective, with recent data indicating greater than 95% effectiveness, rare complications have been reported, including manifestations of autoimmune phenomena. Herein, we re… Show more

“…Out of AAV patients, the majority (20) had positive Myeloperoxidase Antibody (MPO) ANCA with titres ranging from 1.1 units/mL to 3500 units/mL [41][42][43][44][45][46]48,96,116,122,124,128,137,150,160,168,178,182,183,187], and nine were proteinase-3 (PR3) ANCA positive, ranging from 6.7 units to 259 units. Of AAV, 24/30 patients developed biopsy-proven crescentic glomerulonephritis [38,41,42,45,46,48,51,52,55,96,116,122,124,128,130,136,137,150,157,160,168,178,182,187]. Six had pulmonary and renal syndrome [45,55,137,...…”

Six had pulmonary and renal syndrome [45,55,137,157,160,178], whereas three patients had only lung involvement with pulmonary haemorrhage or multi-focal consolidations [43,109]. Two patients were positive for both PR3 and MPO-ANCA [43,44].…”

“…It commonly involves the upper respiratory tract, lungs, and kidneys, with isolated sinonasal disease present in 25% of cases [ 3 ]. GPA belongs to a group of ANCA vasculitis, which also includes eosinophilic granulomatosis with polyangiitis and microscopic polyangiitis [ 4 ]. Although the exact cause of GPA is not known, a complex interaction involving genetics, environmental factors, and microbiomes has been implicated in the pathogenesis, with ANCA presumed to be responsible for inflammation [ 1 , 4 ].…”

Although the exact cause of GPA is not known, a complex interaction involving genetics, environmental factors, and microbiomes has been implicated in the pathogenesis, with ANCA presumed to be responsible for inflammation [ 1 , 4 ]. The diagnosis can be made according to the American College of Rheumatology criteria or the ELK (E stands for ear, nose, and throat or upper respiratory tract, L for lung, and K for kidney) criteria [ 1 ].…”

“…As vaccination rates increase, rare side effects begin to emerge. Cases of small-vessel vasculitis have been reported following the administration of the different COVID-19 vaccines [2][3][4][5][6][7][8][9][10]. Only a few instances of microscopic polyangiitis (MPA) following Pfizer-BioNTech mRNA vaccine administration have been reported in English literature [2][3][4][5][6].…”
