Abstract
Introduction/aim: Although myotonic dystrophy type 2 (DM2) is generally milder than DM1, quality of life (QoL) seems to be similarly impaired in these two disorders. There are no studies that assessed QoL during DM2. Our aim was to assess QoL and disease outcome in patients with DM2 after a five-year follow-up period. Material and Methods: Study originally comprised 49 DM2 patients at baseline. During the five-year period, seven patients died, eight were lost to follow-up, one patient moved, and one refused testing. The Short Form (36) Health Survey (SF-36) and Individualized Neuromuscular Quality of Life (INQoL) questionnaires were administered in 30 patients at baseline and at follow-up (47% males, 54±10 years old). Results: Patients who were retested had better Role Physical (RP) and General Health (GH) scores of the SF-36 and better weakness score of the INQoL compared to non-retested (p>0.05). After the five-year follow-up, none of the SF-36 and INQoL scores differed compared to baseline (p>0.05). Conclusion: QoL did not change in DM2 patients during a five-year period, as measured by both SF-36 and INQoL.
