Survival and mortality of adult‐onset myasthenia gravis in the population of Belgrade, Serbia

: The objective of this study was to estimate mortality and survival in a large cohort of myasthenia gravis (MG) patients from Belgrade, Serbia, during the period 1979–2008. Methods : Data for all patients with MG were collected from hospital records and the Belgrade MG Registry. Results : Within the 30‐year study period, death occurred in 107 (20%) of 562 patients with MG, with MG‐related fatality below 2%. The average MG mortality rate was 1.76 per 1,000,000 population (1.26/1,000,000 women, 2.45/1,000,000 men). A statistically significant increase was recorded for the average standardized mortality rate for all patients ( P  < 0.01). The mean survival from disease onset was 34.3 ± 2.0 years. Significantly shorter survival was observed in men compared with women and in patients older than 50 years compared with younger ones ( P  < 0.01). Discussion : We observed long survival and low frequency of MG‐related fatalities but increasing average standardized mortality rate, most notably in older men with MG. Muscle Nerve 58 : 708–712, 2018
