ABSTRACT

This survey provides an update on the experience of Myasthenia Gravis (MG) patients in Australia. Items were drawn from the 2011 Australian Survey and a 2019 US survey allowing for comparative discussion of survey findings. Patients were recruited through the Myasthenia Alliance Australia. Following consent, patients completed an online survey using REDCap software. Questions included demographics, clinical features, treatment side-effects and quality of life (QOL) scales. Samples for completion of survey sections ranged from N = 242-280 representing a power level of over 80%. Female and seronegative patients reported a significantly greater symptom load, earlier disease onset, longer time to diagnosis, more MG exacerbations, treatment side-effects, and poorer QOL. For exacerbation management there was a higher rate of oral corticosteroid use (66%), a lower use of Intravenous Immunoglobulin (IVIg, 47%) and particularly, Therapeutic Plasma Exchange (TPE, 4.5%) within this sample. Although steroid induced side-effects were rarer (9-34%), a comparatively high use of corticosteroids was reported for current and overall treatments including those for MG crises (52-83%). Common treatment side-effects reported by 57-85% of patients, included fatigue, weight gain, a decrease in the ability to fight infections, gastrointestinal symptoms, and muscle weakness. The impact of MG on daily activities and QOL was considerable, but those who had a thymectomy reported better QOL. The survey identified areas for potential practice improvement in MG treatments (corticosteroids, IVIg, TPE), particularly for exacerbation management, and review is recommended. Further research on gender and antibody status differentials regarding clinical features is required.
