Limb-girdle muscular dystrophy (LGMD) type 2A (calpainopathy) is an autosomal recessive disease caused by mutation in the CAPN3 gene. The aim of this study was to examine genetic and phenotypic features of Serbian patients with calpainopathy. The study comprised 19 patients with genetically confirmed calpainopathy diagnosed at the Neurology Clinic, Clinical Center of Serbia and the Clinic for Neurology and Psychiatry for Children and Youth in Belgrade, Serbia during a ten-year period. Eighteen patients in this cohort had c.550delA mutation, with nine of them being homozygous. In majority of the patients, disease started in childhood or early adulthood. The disease affected shoulder girdle - upper arm and pelvic girdle - thigh muscles with similar frequency, with muscles of lower extremities being more severely impaired. Facial and bulbar muscles were spared. All patients in this cohort, except two, remained ambulant. None of the patients had cardiomyopathy, while 21% showed mild conduction defects. Respiratory function was mildly impaired in 21% of patients. Standard muscle histopathology showed myopathic and dystrophic pattern. In conclusion, the majority of Serbian LGMD2A patients have the same mutation and similar phenotype. © Gaetano Conte Academy - Mediterranean Society of Myology.

Although limb–girdle muscular dystrophies (LGMD) can cause permanent disability, to date there are no studies that examined quality of life (QoL) in these patients. Our aim was to evaluate QoL in patients with LGMD, and to identify the most significant predictors of QoL. The study comprised 46 patients with diagnosis of limb–girdle muscular weakness. QoL in patients was evaluated using two scales—SF-36 questionnaire and the Individualized Neuromuscular Quality of Life questionnaire (INQoL). Following scales were also applied: Epworth Sleepiness Scale (ESS), Hamilton Scale for Depression (HamD), and Krupp’s Fatigue Severity Scale (FSS). Mean SF-36 score was 52.4 ± 23.5, and physical composite score was worse than mental. Total INQoL score was 46.1 ± 20.4, with worst results obtained for weakness, fatigue and independence, while social relationships and emotions showed better results. Significant predictors of worse SF-36 score in LGMD patients were higher fatigue level (β = − 0.470, p < 0.01) and use of assistive device (β = − 0.245, p < 0.05). Significant predictors of worse INQoL score were higher fatigue level (β = 0.514, p < 0.01) and presence of cardiomyopathy (β = − 0.385, p < 0.01). It is of special interest that some of the identified factors that correlated with worse QoL in LGMD patients were amenable to treatment. © 2017, Belgian Neurological Society.
