“…This explains why the incidence and/or prevalence of GCA is not high in Japan. Moreover, our study found no significant differences in the clinical features of GCA between Japan and other countries, although GCA cases are less common in Japan than in the USA or Europe [ 8 ].…”

The epidemiology of systemic vasculitides differs between Japan, Europe and North America. Takayasu’s arteritis occurs frequently in Japan, unlike giant cell arteritis. A collaborative international study comparing the epidemiology of anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis between Japan and the United Kingdom (UK) demonstrated that microscopic polyangiitis and myeloperoxidase-ANCA were more common in Japan whereas granulomatosis with polyangiitis and pronase 3-ANCA were more common in the UK. These differences may be attributed to differences in latitude and genetic backgounds. These findings provide useful information on the aetiology and pathogenesis of primary systemic vasculitides in various geographical regions.

“…It is interesting to note that a study from Beijing, China, demonstrated that 60.7% (54/89) of patients with WG were MPO-ANCA positive, 38.2% (34/89) were PR3-ANCA positive, and patients with MPO-ANCA had multisystem involvement and elevated initial serum creatinine level as compared with PR3-ANCA-positive WG patients [24,25] . …”

Based on studies comparing the prevalence of anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) between Japan and Europe, we have learned that the difference may be due to genetic background and environmental factors, but not to diagnosis or ELISA system for myeloperoxidase and proteinase-3 ANCA. In Japan, microscopic polyangiitis is the most common among AAV, but Wegener’s granulomatosis was present in less than 2 per million patients. Also, one study from Hokkaido reported only 16 patients in a 27-year time frame. A recent retrospective study of renal vasculitis between 2000 and 2004 from Miyazaki prefecture in Japan reported an incidence of microscopic polyangiitis of 14.8 per million, but no patients with Wegener’s granulomatosis or Churg-Strauss syndrome. In the present review, we focus on ANCA-related vasculitis in Japan: (1) AAV and large vessel vasculitis – Takayasu’s arteritis and giant cell arteritis; (2) primary renal vasculitis; (3) epitopes of myeloperoxidase-ANCA in vasculitis in the Japanese population and comparison of ANCA-ELISA systems in Japan and Europe, and finally (4) children with vasculitis in Japan involving Kawasaki disease – a systemic vasculitis.

“…Epidemiology is an important tool for assessing risk and the genetic or environmental relationships while considering the likelihood of a range of differential diagnoses. GCA is the most common systemic vasculitis in patients aged >50 years, and the prevalence of GCA is lower in Asian than Caucasian populations 6. Pereira et al5 reported this finding for a United States population, and concluded that the etiology of GCA is more strongly associated with the genetic background than environmental influences.…”

Arteritic Anterior Ischemic Optic Neuropathy Associated with Giant-Cell Arteritis in Korean Patients: A Retrospective Single-Center Analysis and Review of the Literature

Background and Purpose The aim of this study is to report the relative incidence of arteritic anterior ischemic optic neuropathy (AAION) associated with giant-cell arteritis (GCA) in a single-center and evaluate the clinical features of AAION in Korean patients. Methods The medical records of patients with presumed AION who visited our hospital from January 2013 to August 2018 were examined retrospectively. The patients were divided into two groups: AAION associated with GCA, and non AION (NAION). We additionally reviewed the literature and identified all cases of AAION in Korean and Caucasian patients. We evaluated the clinical data including the initial and final best-corrected visual acuities, fundus photographs, visual field tests, fluorescein angiography, and contrast-enhanced MRI, and compared the data with those for Caucasian patients in the literature. Results Of the 142 patients with presumed AION, 3 (2.1%) were diagnosed with AAION and 139 (97.9%) were diagnosed with NAION. Seven Korean patients with AAION associated with GCA were identified in our data and the literature review. We found no difference in any clinical features other than laterality: four of the seven Korean patients had bilateral involvement. Moreover, the optic nerve sheath was enhanced in two of our Korean patients. Conclusions AAION associated with GCA is a very rare condition compared to NAION in Korea. However, GCA should be considered in all cases of ischemic optic neuropathy because AAION is associated with poor visual outcome, and sometimes presents bilaterally.
