“…Second, the group of LVV patients is not homogeneous. We have no explanation why we did not identify any LVV patients associated to MPA or EGPA, even though several such cases are described in the literature [2,7,[14][15][16][17][18][19]. Third, not all patients had the same diagnostic approach using different methods of investigation.…”

“…Some authors refer to polyangiitis overlap syndromes, a type of systemic vasculitis that represents several diagnostic categories [2,3]. Indeed, there are several reports of patients diagnosed with both GCA and GPA [2][3][4][5][6][7][8][9][10][11][12][13], MPA [7,[14][15][16][17][18], or EGPA [19]. A retrospective cohort of the Mayo Clinic identified five cases of temporal arteritis among 345 patients with GPA [4].…”

Prevalence of large vessel vasculitis in ANCA-associated vasculitis: a retrospective cohort study

et al. 2021

ANCA-associated vasculitis (AAV) in general involves small blood vessels and includes granulomatosis with polyangiitis (GPA), eosinophilic granulomatosis with polyangiitis (EGPA), and microscopic polyangiitis (MPA). Although reported in a few studies, the prevalence of large vessel vasculitis (LVV) in patients with AAV remains to be further explored. The goal of the present study was to assess the prevalence of LVV in a cohort of patients with AAV and to characterize this population. We conducted a ten-year retrospective study of a single-center cohort of AAV, including 101 patients with GPA (n = 58), EGPA (n = 28), MPA (n = 15), and compared the groups with or without associated LVV. LVV was diagnosed in five patients, two with aortitis and three with temporal arteritis, corresponding to a total prevalence of 5.0% [95% CI 1.6–11.2%]. This value was significantly higher than the estimated prevalence of LVV in the normal Swiss population (OR 234.9 95% CI 91.18–605.2, p < 0.001). All five patients had GPA, whereas no cases with EGPA or MPA were identified. Anti-PR3 antibodies were detected in four out of five patients, anti-MPO in one patient. Since LVV can occur in a significant proportion of patients with GPA, evaluation for LVV may be considered systematically in the diagnostic workup of AAV.

“…Notably, it is exceedingly rare for MPA to present with temporal artery involvement, as only a small handful of such cases have been reported to date [5][6][7][8][9][10][11][12][13]. In our review of the literature, we identified only 14 cases of MPA reported to involve the temporal artery (Table 1).…”

Microscopic polyangiitis (MPA) is an idiopathic autoimmune disease characterized by systemic vasculitis. While the lungs and kidneys are the major organs affected by MPA, it is known to involve multiple organ systems throughout the body. Temporal artery involvement is a very rare finding in MPA. This report presents a patient whose initial presentation was consistent with giant cell arteritis but was ultimately found to have microscopic polyangiitis. It highlights the importance of considering alternative types of vasculitis in the differential diagnosis for patients with atypical temporal artery biopsy findings.

A concomitant case of giant cell arteritis and microscopic polyangiitis with hemoperitoneum by rupture of the gastroepiploic artery

et al. 2012

View full text Add to dashboard Cite

Giant cell arteritis (GCA) mainly involves large-sized arteries, while microscopic polyangiitis (mPA), characterized by pauci-immune necrotizing vasculitis, mainly affects small-sized vessels. We report a very rare concomitant case of GCA diagnosed by temporal artery biopsy and mPA with a high titer of myeloperoxidase antineutrophil cytoplasmic antibody, exacerbation of interstitial pneumonia, and suspected rapidly progressive glomerulonephritis. The patient died by sudden rupture of the gastroepiploic artery (medium-sized vessel), which may have been triggered by GCA and/or mPA.
