Abstract
Background
Immunomodulation, including IVIG and plasma exchange, is useful for a crisis or severe exacerbation. Plasma exchange may be slightly faster and more effective in a myasthenic crisis than IVIG. The aim of the current study was to determine the changes in the quality of life (QOL) after plasmapheresis and factors influencing these changes.
Results
This study was conducted on 98 MG patients diagnosed as moderate to severe myasthenia gravis (according to Myasthenia Gravis Foundation of America classification), 81 patients received alternate day 5 sessions plasmapheresis (TPE group) and 17 patients were on medical treatment only (control group). All patients were subjected to full history, through clinical neurological evaluation and scored with quantitative myasthenia gravis (QMG) score for MG severity at start and after 1 m. Both groups completed the QOL questionnaire at baseline and after 1 month. The MG-QOL-15 scores were computed and we analyzed the change in the QOL scores from baseline to after plasmapheresis groups and compared it with the results for the control group. The scores in QOL scales had significantly decreased after plasmapheresis, and the improvement in QOL scores had a good correlation with the decrease in QMGS. The improvement in QOL and QMG was significantly correlated with younger age, female gender, shorter duration of the illness, presence of AchR antibodies, antibody titer, and thymus hyperplasia.
Conclusion
Plasmapheresis is effective in improving quality of life in myasthenia gravis patients and this improvement influenced by age, gender, duration of illness, presence of AchR antibodies and their titer, and the thymus pathology.

Abstract
INTRODUCTION We sought to translate, cross-culturally adapt, and evaluate the internal consistency and validity of the Chinese version of the 15-Item Myasthenia Gravis Quality of Life (MG-QOL15). METHODS Translation and cross-cultural adaptation of the MG-QOL15 were performed. We used Cronbach's α to test internal consistency, one-way analysis of variance to test construct validity, and Pearson or Spearman correlations to test discriminant and concurrent validity. RESULTS We enrolled 168 outpatients. Internal consistency was excellent (Cronbach's α = 0.928). The MG-QOL15 discriminated MG severity as stratified by the MG Composite (MGC; P < 0.001) and Osserman class (P = 0.01). Concurrent validity was low to moderate with the subscales of the 36-item Short Form (-0.31 to ∼-0.59), MGC (r = 0.46), and Myasthenia Gravis Activities of Daily Living profile (r = 0.54). DISCUSSION The Chinese MG-QOL15 showed comparable construct, discriminant and concurrent validity, and internal consistency with to the original version. Muscle Nerve 59:95-99, 2019.

Abstract
It is known that quality of life in myasthenia gravis is positively correlated with subjective sleep quality, still no data is available regarding the relationship between QOL and polysomnographically detected sleep parameters and disorders. In this study, we tried to highlighten this relationship, by performing polysomnography. Sleep-related complaints were evaluated in face-to-face interviews with 19 clinically stable MG patients and 26 healthy controls. During the interviews questionnaires assessing sleep quality, excessive daytime sleepiness, fatigue, depression, anxiety, and Turkish version of the MG-QOL 15-item scale [(MG-QOL15(T)] were administered and then an overnight polysomnography was performed. Sleep disorders, especially obstructive sleep apnea and fatigue were higher, whereas subjective sleep duration was significantly lower, in patients than controls. Excessive daytime sleepiness and poor sleep quality were not different between patients and controls. Other than percentage of sleep stage III, which was negatively correlated with MG-QOL15(T) scores, neither other sleep parameters nor sleep disorders were correlated with MG-QOL15(T) scores. MG composite, subjective sleep duration, fatigue severity and Hamilton depression rating scale scores were found to be positively correlated with MG-QOL15(T) scores. It was shown that decreasing disease severity and enhancing psychological well-being will improve patients' quality of life. We recommend that our findings should be repeated in a large prospective cohort of MG patients.

Abstract
Myasthenia gravis (MG) is a neuromuscular autoimmune disease characterized by skeletal muscle weakness which can impact motor function and, furthermore, produce negative impact on the health-related quality of life (HRQOL). OBJECTIVE To evaluate the predictors for HRQOL in patients with MG. METHODS Eighty patients were evaluated with the MG Foundation of America classification and the MG Composite scale. HRQOL was estimated by the MGQOL15, while anxious and depressive symptoms were evaluated with the Hospital Anxiety and Depression Scale (HAD). RESULTS The mean age of patients was 41.9 years with mean illness duration of 13.5 years. Almost half of the patients (43.75%) had significant anxiety and more than a quarter (27.50%) had depressive symptoms. Factors that influenced the HRQOL in MG were skeletal muscle weakness and anxiety and depressive symptoms (p < .001 in logistic regression model). CONCLUSION Anxiety and depressive symptoms, besides motor symptoms, influence HRQOL in MG. Mental health must be a clinical focus in addition to the treatment of somatic symptoms during the course of MG.

Abstract
INTRODUCTION The Myasthenia Gravis-Activities of Daily Living (MG-ADL) profile scale is a simple-to-use instrument. We aimed to validate this scale in the Korean language and compare physician- and self-assessed MG-ADL scores (pMG-ADL-K and sMG-ADL-K). METHODS pMG-ADL-K and sMG-ADL-K and MG Composite (MGC) scores were obtained from patients. The correlation between pMG-ADL-K and MGC and the relationship between the pMG-ADL-K and sMG-ADL-K were assessed using the Cronbach α and the Spearman coefficient. By intraclass correlation coefficient (ICC), the reliability of each sub-item of pMG-ADL-K and sMG-ADL-K was evaluated. RESULTS We included data from 40 patients. The pMG-ADL-K score showed a strong correlation with the MGC score (rho = 0.80, P < 0.01). The Cronbach α was 0.98 between pMG-ADL-K and sMG-ADL-K, and sub-items showed good consistency (ICC 0.684-0.985, P < 0.001). DISCUSSION The MG-ADL-K is a valid tool and the sMG-ADL-K shows excellent correlation with pMG-ADL-K. Both the pMG-ADL-K and sMG-ADL-K can be used to measure MG severity.

Abstract
Objective To perform the translation, cross-cultural adaptation and validation of the Quantitative Myasthenia Gravis Score (QMGS) to Brazilian Portuguese in accordance with international ethical standards. Methods The following steps were taken: (1) implementation of the translation protocol and transcultural adaptation, (2) validation of the adapted content, and (3) assessment of reliability. To check intra- and inter-observer reproducibility, each patient underwent two interviews with interviewer-A and one with B. The QMGS was compared to the Myasthenia Gravis Composite Scale and Myasthenia-specific Quality of Life Questionnaire. Results Our study group consisted of 30 patients, with a mean age of 47.6±11.4 years and a mean duration of illness of 11.33±8.49 years. Correlation between the QMGS and MGC was very strong (r = 0.928; p < 0.001) and substantial between the QMGS and MG-QOL 15 (r = 0.737; p < 0.001). Conclusion The Brazilian Portuguese translation, and validation of the QMGS was successfully performed.

Abstract
INTRODUCTION The MG-QOL15 is a validated, health-related quality of life (HRQOL) measure for myasthenia gravis (MG). Widespread use of the scale gave us the opportunity to further analyze its clinimetric properties. METHODS We first performed Rasch analysis on >1,300 15-item Myasthenia Gravis Quality of Life scale (MG-QOL15) completed surveys. Results were discussed during a conference call with specialists and biostatisticians. We decided to revise 3 items and prospectively evaluate the revised scale (MG-QOL15r) using either 3, 4, or 5 responses. Rasch analysis was then performed on >1,300 MG-QOL15r scales. RESULTS The MGQOL15r performed slightly better than the MG-QOL15. The 3-response option MG-QOL15r demonstrated better clinimetric properties than the 4- or 5-option scales. Relative distributions of item and person location estimates showed good coverage of disease severity. CONCLUSIONS The MG-QOL15r is now the preferred HRQOL instrument for MG because of improved clinimetrics and ease of use. This revision does not negate previous studies or interpretations of results using the MG-QOL15. Muscle Nerve 54: 1015-1022, 2016.

Abstract
OBJECTIVES The aims of the current study were 1) to evaluate the reliability and validity of the Brazilian version of the 15-item Myasthenia Gravis Quality of Life Scale and 2) to investigate the quality of life of Brazilian patients with myasthenia gravis and its determinants. METHODS This cross-sectional study included 69 patients with myasthenia gravis who underwent neurological evaluation and completed questionnaires regarding quality of life (the 36-item Short Form of the Medical Outcomes Study and the 15-item Myasthenia Gravis Quality of Life Scale), anxiety and depressive symptoms. RESULTS The Brazilian version of the 15-item Myasthenia Gravis Quality of Life Scale showed high internal consistency and good concurrent validity with the 36-item Short Form of the Medical Outcomes Study and its subscales. Determinants of quality of life in Brazilian patients with myasthenia gravis included the current status of myasthenia gravis as assessed by the Myasthenia Gravis Composite, the current prednisone dose and the levels of anxiety and depression. CONCLUSION The Brazilian version of the 15-item Myasthenia Gravis Quality of Life Scale is a valid instrument. Symptom severity, prednisone dosage and anxiety and depression levels impact the quality of life of patients with myasthenia gravis.
