Burden of disease in myasthenia gravis: taking the patient's perspective.


ABSTRACT:

Background

Myasthenia gravis (MG) leads to exertion-dependent muscle weakness, but also psychological and social well-being are limited. We aim to describe the burden of disease in MG including sociodemographic, economical, psychosocial as well as clinical aspects, to compare health-related quality of life (HRQoL) of patients with MG to the general population (genP) and to explore risk factors for a lower HRQoL.

Methods

This case-control study was conducted with MG patients of the German Myasthenia Association. A questionnaire-based survey included sociodemographic and clinical data as well as standardized questionnaires, e.g. the Short Form Health (SF-36). HRQoL was compared to genP in a matched-pairs analysis. Participants of the German Health Interview and Examination Survey for Adults (DEGS1) served as control group.

Results

In our study, 1660 MG patients participated and were compared to 2556 controls from the genP. Patients with MG showed lower levels of physical functioning (SF-36 mean 56.0, SD 30.3) compared to the genP (mean 81.8, SD 22.1, adjusted difference: 25, 95% CI 22-29) and lower mental health sub-score (SF-36 mean 67.3, SD 19.8, vs. 74.1, SD 16.7, adjusted difference: 5, 95% CI 2-8). Female gender, higher age, low income, partnership status, lower activities of daily life, symptoms of depression, anxiety and fatigue and self-perceived low social support were associated with a lower HRQoL in MG patients.

Discussion

HRQoL is lower in patients with MG compared to genP. The burden of MG on patients includes economic and social aspects as well as their emotional well-being. New therapies must achieve improvements for patients in these areas.
