The Influence of Loneliness and Anxiety Levels on MG-Specific Quality of Life in Patients with Myasthenia Gravis during the COVID-19 Pandemic

Background Myasthenia gravis (MG) is one of the most common autoimmune diseases and can occur at any age. The study aimed to evaluate the influence of loneliness and anxiety levels on MG-specific quality of life in patients with myasthenia gravis during the COVID-19.MethodsThis was a cross sectional study and the population consisted of patients with MG throughout Turkey between August 1 and October 31, 2021. The study was completed with 149 patients who met the inclusion criteria and agreed to participate in the research.Results The mean MG-specific quality of life score was 44.15 +/- 13.77, the mean UCLA loneliness scale was 56.13 +/- 11.55, and the mean Beck Anxiety Inventory score was 24.63 +/- 13.78. There was a moderately positive linear relationship between the participants' MG-specific quality of life (r = 0.589; p < 0.001) and the Beck Anxiety Inventory, and there was a weak negative linear relationship with the UCLA loneliness scale (r = 0.323; p < 0.001). The variables affecting the MG-specific quality of life were the following: anxiety, loneliness, employment status, income level, symptom levels, and having another chronic disease; a multiple regression model was created with these variables, and it was observed that anxiety and loneliness affected participants' MG-specific quality of life. The variables in the model explained 52.9% of the MG-specific quality of life, and the model was statistically significant (p < 0.001).Conclusion The study determined that the participants had intense loneliness, moderate anxiety, and a moderate MG-specific quality of life. The participants' MG-specific quality of life has decreased as their anxiety has increased, and the partici-pants' MG-specific quality of life has increased as their loneliness has increased
