METHODS: A systematic search of databases was conducted according to the PRISMA guidelines. Articles reporting sex distribution and age of onset for AQP4 antibody-associated NMSOD were reviewed. An initially inclusive approach involving exploration with regression meta-analysis was followed by an analysis of just AQP4 antibody positive cases.
RESULTS: A total of 528 articles were screened to yield 89 articles covering 19,415 individuals from 88 population samples. The female:male sex ratio was significantly influenced by the proportion of AQP4 antibody positive cases in the samples studied (p
BACKGROUND: Clinically, MOGAD can be associated with significant disability; however, its socioeconomic consequences for adults are barely reported.
METHODS: Participants of potential working age (18-70 years old) with neurologist-diagnosed MOGAD were recruited from clinical sites in 13 countries, April 2022 to August 2023. Each participant completed a one-time survey. Regression models assessed associations with post-MOGAD (1) unemployment and (2) work hours.
RESULTS: A total of 117 participants (66.7% female), mean age 39.7 years, median disease duration 3 years (25th, 75th percentile: 1, 7) were analyzed. Employment post-MOGAD reduced from 74 (63.2%) to 57 (48.7%) participants. Participants employed pre-diagnosis reduced their work hours, on average, from 31.6 hours/week to 19.5 hours/week post-diagnosis. Residence in a high-income country was statistically significantly associated with post-diagnosis employment and higher weekly work hours. Depressed mood was associated with unemployment. MOGAD-related pain and history of myelitis were independently associated with lost work hours.
CONCLUSION: MOGAD can have significant impacts on adult employment, particularly in non-high-income countries. Depressed mood and pain are potentially modifiable factors related to socioeconomic status in MOGAD.
