Prevalence of neuromyelitis optica spectrum disorder in the multi-ethnic Penang Island, Malaysia, and a review of worldwide prevalence

A population‐based epidemiological study of neuromyelitis optica spectrum disorder in Hungary

“…All rights reserved. The Hungarian estimates are higher than in other large studies in Caucasian population 4,7,10,[16][17][18] , similar to the results of a smaller study from Wales 22 but lower than in Asian or African populations 5,7,8,23 and other smaller studies in Caucasian population 5,24 (table 5). However, the small population size may lead to broader confidence intervals and considerable effect of random error resulting in less precise estimates.…”

“…5 Several studies have indicated that ethnicity may have a considerable influence on the epidemiology of NMOSD. 4,5,7,10,16,23 Support for this observation has been emerged by studies where different ethnic groups were investigated in the same geographic area. 4,7,10,16,23 Over half of the Hungarian NMOSD patients according to the 2015 IPND criteria fulfilled the 2006 Wingerchuk criteria, as well, similarly to previous studies.…”

“…16 The prevalence of NMOSD in Asian population was reported between 1.99 and 4.1 per 100,000, but there is a lack of reliable incidence data. 8,21,23,26 The highest prevalence and incidence data were…”

“…A Cuban study reported a higher prevalence of 0.8/10 5 amid blacks and mixed individuals and 0.43/ 10 5 amid white ones. In Asia, there was also a great range of prevalence values: in Japan, it varied from 0.9 to 4.1/ 10 5 (Houzen et al, 2012 and2017), in Southern India it was 2.7/10 5 (Pandit and Kundapur, 2014), in Penang Island, Malaysia, it was 1.99/10 5 (3.3/10 5 in Chineses and only 0.43/10 5 in Malays) (Hor et al, 2018). In Iran, three different studies reported prevalences between 0.81 and 1.9 per 10 5 (Etemadifar et al, 2014;Kashipazha et al, 2015;Eskandarieh et al, 2017).…”
