Introduction: Myotonic dystrophy type 2 (DM2) is a rare autosomal dominant multisystemic disease with highly variable clinical presentation. Several case reports and one cohort study suggested a significant association between DM2 and autoimmune diseases (AIDs). Aim: The aim of this study is to analyze the frequency and type of AIDs in patients with DM2 from the Serbian DM registry. Patients and Methods: A total of 131 patients with DM2 from 108 families were included, [62.6% women, mean age at DM2 onset 40.4 (with standard deviation 13) years, age at entering the registry 52 (12.8) years, and age at analysis 58.4 (12.8) years]. Data were obtained from Akhenaten, the Serbian registry for DM, and through the hospital electronic data system. Results: Upon entering the registry, 35 (26.7%) of the 131 patients with DM2 had AIDs including Hashimoto thyroiditis (18.1%), rheumatoid arthritis, diabetes mellitus type 1, systemic lupus, Sjogren's disease, localized scleroderma, psoriasis, celiac disease, Graves's disease, neuromyelitis optica, myasthenia gravis, and Guillain-Barre syndrome. At the time of data analysis, one additional patient developed new AIDs, so eventually, 36 (28.8%) of 125 DM2 survivors had AIDs. Antinuclear antibodies (ANAs) were found in 14 (10.7%) of 63 tested patients, including 12 without defined corresponding AID (all in low titers, 1:40 to 1:160). Antineutrophil cytoplasmic antibodies (ANCAs) were negative in all 50 tested cases. The percentage of women was significantly higher among patients with AIDs (82.9% vs. 55.2%, p <0.01). Conclusion: AIDs were present in as high as 30% of the patients with DM2. Thus, screening for AIDs in DM2 seems reasonable. Presence of AIDs and/or ANAs may lead to under-diagnosis of DM2.

Introduction: Myotonic dystrophy type 2 (DM2) is a rare, multisystemic, autosomal dominant disease with highly variable clinical presentation. DM2 is considered to be highly underdiagnosed. Objective: The aim of this study was to determine which symptoms, signs, and diagnostic findings in patients referred to neurological outpatient units are the most indicative to arouse suspicion of DM2. We tried to make a useful and easy-to-administer clinical scoring system for early diagnosis of DM2-DM2 early diagnosis score (DM2-EDS). Patients and methods: Two hundred ninety-one patients with a clinical suspicion of DM2 were included: 69 were genetically confirmed to have DM2, and 222 patients were DM2 negative. Relevant history, neurological, and paraclinical data were obtained from the electronic medical records. Results: The following parameters appeared as significant predictors of DM2 diagnosis: cataracts (beta = 0.410, p < 0.001), myotonia on needle EMG (beta = 0.298, p < 0.001), hand tremor (beta = 0.211, p = 0.001), positive family history (beta = 0.171, p = 0.012), and calf hypertrophy (beta = 0.120, p = 0.043). In the final DM2-EDS, based on the beta values, symptoms were associated with the following values: cataracts (present 3.4, absent 0), myotonia (present 2.5, absent 0), tremor (present 1.7, absent 0), family history (positive 1.4, negative 0), and calf hypertrophy (present 1.0, absent 0). A cut-off value on DM2-EDS of 3.25 of maximum 10 points had a sensitivity of 84% and specificity of 81% to diagnose DM2. Conclusion: Significant predictors of DM2 diagnosis in the neurology outpatient unit were identified. We made an easy-to-administer DM2-EDS score for early diagnosis of DM2. © 2022, The Author(s).

Myotonic dystrophy type 2 (DM2) is an autosomal dominant multisystemic disorder. Previous studies conducted on small cohorts of DM2 patients indicated presence of a cognitive dysfunction. We aimed to assess cognitive functions in a larger cohort of Serbian DM2 patients using an extensive battery of neuropsychological tests. The study included 76 patients with a genetically confirmed DM2, 68 of whom had all tests for different cognitive domains performed. Patients underwent clinical and neuropsychological testing, including cognitive screening and assessment of general intellectual level, attention, executive and visuospatial abilities, memory, and language functions. Only 6% of patients achieved a below-average score on the general intellectual level test. Cognitive screening tests indicated presence of cognitive deficits in 5.5% of patients according to the Mini Mental State Examination test and 25.8% according to the Addenbrooke's Cognitive Examination Revised test. Twenty-four (35.3%) patients had a cognitive impairment (being two standard deviations out of norm in at least two cognitive domains). Around one quarter of DM2 patients had a significant cognitive impairment that interfered with their everyday functioning. Patients with significant cognitive impairment were older at testing and at disease onset, less educated, and had more severe muscle weakness. © 2022 The Authors

Background/Objectives: The thyroid gland has an important influence on the heart. Long-term exposure to high levels of thyroid hormones may lead to cardiac hypertrophy and dysfunction. The aim of the study was to evaluate the morphological and functional changes in the left ventricle in patients with hyperthyroidism caused by Graves’ disease (GD) in comparison with healthy individuals, as well as to investigate potential differences in these parameters in GD patients in relation to the presence of orbitopathy. Methods: The prospective study included 39 patients with clinical manifestations and laboratory confirmation of GD and 35 healthy controls. All participants underwent a detailed echocardiographic examination. The groups were compared according to demographic characteristics (age and gender), heart rate and echocardiographic characteristics. Results: The patients with hyperthyroidism caused by GD had significantly higher values of left ventricular diameter, left ventricular volume and left ventricular mass compared to the healthy controls. In addition, hyperthyroidism significantly influenced the left ventricular contractility and led to the deterioration of the systolic and diastolic function, as shown together by longitudinal strain, color Doppler and tissue Doppler imaging. However, the patients with GD and orbitopathy showed better left ventricular function than those without orbitopathy. Conclusions: Besides the confirmation of previously known findings, our study indicates possible differences in echocardiographic parameters in GD patients in relation to the presence of orbitopathy. Further investigation with larger samples and meta-analyses of data focused on the evaluation of echocardiographic findings in the context of detailed biochemical and molecular analyses is required to confirm our preliminary results and their clinical significance. © 2024 by the authors.
