Objectives. Cross-sectional studies reported fatigue in 50-90% of patients with myotonic dystrophy type 1 (DM1). The aim of this research was to assess frequency of fatigue in DM1 patients during a seven-year period. Materials and methods. Study included 64 DM1 patients at baseline (50% males, age 42 ± 12 years), and 38 after seven years. Following scales were used: Muscular Impairment Rating Scale (MIRS), Fatigue Severity Scale (FSS, score equal to or greater than 36 indicates significant fatigue), and Daytime Sleepiness Scale (DSS, score of more than six is considered significant). Results. At baseline, 54% of DM1 patients had fatigue and 46% had excessive daytime sleepiness (EDS). Ten (32%) patients with fatigue had no EDS. At the baseline, patients with fatigue were older, were more likely to had adult-onset DM1, worse MIRS and DSS compared to the patients without fatigue. After seven years, FSS score increased (34 ± 15 vs 48 14, p < 0.01), fatigue was found in 82% of patients, and EDS in 60%. Still eight (26%) patients with fatigue had no EDS. Fatigue progression did not parallel MIRS increase. Conclusions. Fatigue is a common symptom of DM1 and its progression during time did not correlate with the progression of muscle weakness. © Gaetano Conte Academy - Mediterranean Society of Myology

Myotonic dystrophy type 2 (DM2) is a slowly progressive, autosomal-dominant disease. This is a multisystemic disorder that affects the heart, which is one of the main causes of morbidity and mortality in DM2. The aim of the study was to define cardiac impairments in patients with DM2 and its association with sociodemographic and clinical features of patients. This retrospective study comprised 62 adult patients with DM2 hospitalized at the Neurology Clinic, Clinical Center of Serbia from 2013 until 2018, who underwent electrocardiography (ECG) and echocardiography examinations. Hypertension was observed in 42% of DM2 patients. One-fifth of DM2 patients had bradycardia, while other conduction and rhythm impairments were rare. Only one patient had a pacemaker implanted because of the first degree AV block associated with incomplete left bundle branch block. Echocardiography showed diastolic dysfunction of the left ventricle in 44% of patients, while systolic dysfunction was found in only 4%. Cardiomyopathy was observed in 18% of patients, of whom three-fourth had dilated type. Cardiac conduction and rhythm defects are relatively rare in DM2, while diastolic dysfunction is common. This suggests that regular ECG and echocardiography screening is needed in DM2. Adequate therapy should be introduced in patients with DM2 on time to reduce the frequency of heart complications and to prevent premature death. © 2018, Belgian Neurological Society.
