PURPOSE: An increasing number of patients with Duchenne muscular dystrophy (DMD) now have access to improved standard of care and disease modifying treatments, which improve the clinical course of DMD and extend life expectancy beyond 30 years of age. A key issue for adolescent DMD patients is the transition from paediatric- to adult-oriented healthcare. Adolescents and adults with DMD have unique but highly complex healthcare needs associated with long-term steroid use, orthopaedic, respiratory, cardiac, psychological, and gastrointestinal problems meaning that a comprehensive transition process is required. A sub-optimal transition into adult care can have disruptive and deleterious consequences for a patient's long-term care. This paper details the results of a consensus amongst clinicians on transitioning adolescent DMD patients from paediatric to adult neurologists that can act as a guide to best practice to ensure patients have continuous comprehensive care at every stage of their journey. METHODS: The consensus was derived using the Delphi methodology. Fifty-three statements were developed by a Steering Group (the authors of this paper) covering seven topics: Define the goals of transition, Preparing the patient, carers/parents and the adult centre, The transition process at the paediatric centre, The multidisciplinary transition summary - Principles, The multidisciplinary transition summary - Content, First visit in the adult centre, Evaluation of transition. The statements were shared with paediatric and adult neurologists across Central Eastern Europe (CEE) as a survey requesting their level of agreement with each statement. RESULTS: Data from 60 responders (54 full responses and six partial responses) were included in the data set analysis. A consensus was agreed across 100% of the statements. CONCLUSIONS: It is hoped that the findings of this survey which sets out agreed best practice statements, and the transfer template documents developed, will be widely used and so facilitate an effective transition from paediatric to adult care for adolescents with DMD.

BACKGROUND: This paper details the results of an evaluation of the level of consensus amongst clinicians on the use of ataluren in both ambulatory and non-ambulatory patients with nonsense mutation Duchenne muscular dystrophy (nmDMD). The consensus was derived using a modified Delphi methodology that involved an exploration phase and then an evaluation phase. METHODS: The exploration phase involved 90-minute virtual 1:1 interviews of 12 paediatric neurologists who cared for 30-120 DMD patients each and had patient contact every one or two weeks. The respondents managed one to ten nmDMD patients taking ataluren. The Discussion Guide for the interviews can be viewed as Appendix A. Following the exploration phase interviews, the interview transcripts were analysed by an independent party to identify common themes, views and opinions and developed 43 draft statements that the Steering Group (authors) reviewed, refined and endorsed a final list of 42 statements. Details of the recruitment of participants for the exploration and evaluation phases can be found under the Methods section. RESULTS: A consensus was agreed (> 66% of respondents agreeing) for 41 of the 42 statements using results from a consensus survey of healthcare professionals (n = 20) experienced in the treatment of nmDMD. CONCLUSIONS: The statements with a high consensus suggest that treatment with ataluren should be initiated as soon as possible to delay disease progression and allow patients to remain ambulatory for as long as possible. Ataluren is indicated for the treatment of Duchenne muscular dystrophy that results from a nonsense mutation in the dystrophin gene, in ambulatory patients aged 2 years and older (see Summary of Product Characteristics for each country).

In this prospective study involving 37 Duchenne muscular dystrophy (DMD) patients aged 8-18 years and older, we examined the impact of neurological and cardiac factors on quality of life (QoL). Our findings revealed a negative correlation between upper limb movement and overall mobility, self-service, and usual activities. Ambulatory and non-ambulatory DMD patients showed significant differences in mobility-related parameters. Cardiac evaluations demonstrated associations between mitral annular plane systolic excursion (MAPSE) and mobility-related aspects. The PEDSQL 3.0 neuromuscular model questionnaire further highlighted age-related and movement-related correlations with QoL. The loss of ambulatory status and reduced upper limb movement were negatively associated with QoL, while upper limb movement positively correlated with septal MAPSE. However, no significant associations were found between MAPSE and anxiety/depression. These findings underscore the multifaceted impact of DMD on QoL and emphasize the importance of considering both neurological and cardiac factors in comprehensive patient care.

Duchennova svalová dystrofie (DMD) je se svou incidencí 1 : 5 000 nově narozených chlapců nejčastějším svalovým onemocněním dětského věku. Je způsobena mutací v genu pro dystrofin, který se nalézá na X chromozomu. První příznaky zahrnují obvykle opoždění motorického vývoje, potíže s běháním nebo s chůzí do a ze schodů. Později se přidává slabost horních končetin, respirační insuficience a srdeční potíže, které bývají mezi 25.-30. rokem věku příčinou smrti.
Duchenne muscular dystrophy (DMD) is with its incidence 1 : 5 000 newborn males the most frequent muscle disease in childhood. It is caused by mutation in dystrophin gene located on X chromosome. First symptoms of DMD include delayed motor milestones, difficult running or climbing stairs, later we can see weakness of shoulder girdle. Cardiomyopathy and respiratory failure most often occur in the third decade. Because of new treatment possibilities, it is necessary to confirm diagnose as soon as possible. E. g. ataluren as a treatment for DMD boys can be used from the age of 2 years. We should test creatine kinase (which elevation more than 100x is typical for DMD) in all boys suspected from DMD as well as in all boys when we do any blood tests.

Kongenitální svalové dystrofie (CMD) jsou z historické definice heterogenní skupinou svalových chorob, které jsou charakterizovány časným nástupem svalového onemocnění a dystrofickým nálezem při histopatologickém vyšetření svalové tkáně. Recentní pokroky v molekulární genetice pohled na celou skupinu kongenitálních svalových dystrofií mění. Pokračující dešifrování genetického podkladu a narůstající počet potvrzených genetických diagnóz poukazuje na výraznou genetickou a klinickou heterogenitu celé skupiny CMD a dřívější klinicko-histopatologické členění ztrácí na významu. Tento text stručně shrnuje dosavadní poznatky a doplňuje je o krátké kazuistiky z klinické praxe.
From a historical definition, congenital muscular dystrophies are a heterogenous group of muscle disorders characterized by early-onset muscle disease with histopathological evidence of a dystrophic process. Recent progress of molecular genetics has changed the perspective of the entire group. Continuous deciphering of the genetic background and increasing number of genetically confirmed cases highlights a significant genetic and clinical heterogenicity and makes former clinico-histopathological classifications less useful. It also blurs the classification barriers between congenital muscular dystrophies, limb girdle muscular dystrophies and congenital myopathies groups as they share and overlap at clinical, morphological and genetic level. This text provides a brief summary of the current knowledge accompanied by clinical vignettes from the clinical practice.

Duchennova a Beckerova svalová dystrofie, které jsou způsobeny mutacemi v genu pro dystrofin, patří k nejčastějším svalovým onemocněním dětského věku. Příznaky zahrnují vlastní motorické postižení, později se přidává i respirační insuficience a srdeční potíže, které bývají mezi 25.-30. rokem věku příčinou smrti. Kromě hybného postižení nacházíme u celé řady pacientů neuropsychiatrické poruchy zahrnující zejména poruchy intelektu, poruchy autistického spektra, poruchu aktivity a pozornosti a obsedantně kompulzivní chorobu. Podle publikovaných studií je jejich incidence u těchto pacientů vyšší, než je tomu v běžné populaci. Pravděpodobným vysvětlením je nedostatek dystrofinu v neuronech.
Duchenne/Becker muscular dystrophy, caused by mutations in dystrophin gene,is one of the most frequent muscular dystrophies. Symptoms of DMD include typical movement problems, cardiomyopathy and respiratory failure most often occur in the third decade. In many patients we can find not only movement problems but also neuropsychiatric disorders, esp. autism spectrum disorders, attention-deficit hyperactivity disorder and obsessive-compulsive disorder. Their incidence is higher than in other population. Probabaly it due to lack of dystrophin in neurons.
BACKGROUND: Duchenne muscular dystrophy (DMD) manifests in males mainly by skeletal muscle impairment, but also by cardiac dysfunction. The assessment of the early phases of cardiac involvement using echocardiography is often very difficult to perform in these patients. The aim of the study was to use cardiac magnetic resonance (CMR) strain analysis and mitral annular plane systolic excursion (MAPSE) in the detection of early left ventricular (LV) dysfunction in DMD patients. METHODS AND RESULTS: In total, 51 male DMD patients and 18 matched controls were examined by CMR. MAPSE measurement and functional analysis using feature tracking (FT) were performed. Three groups of patients were evaluated: A/ patients with LGE and LV EF < 50% (n = 8), B/ patients with LGE and LVEF ≥ 50% (n = 13), and C/ patients without LGE and LVEF ≥ 50% (n = 30). MAPSE and global LV strains of the 3 DMD groups were compared to controls (n = 18). Groups A and B had significantly reduced values of MAPSE, global longitudinal strain (GLS), global circumferential strain (GCS), and global radial strain (GRS) in comparison to controls (p < 0.05). The values of MAPSE (11.6 ± 1.9 v 13.7 ± 2.7 mm) and GCS (- 26.2 ± 4.2 v - 30.0 ± 5.1%) were significantly reduced in group C compared to the controls (p < 0.05). CONCLUSION: DMD patients had decreased LV systolic function measured by MAPSE and global LV strain even in the case of normal LV EF and the absence of LGE. FT and MAPSE measurement provide sensitive assessment of early cardiac involvement in DMD patients.

Some muscular dystrophies may have a negative impact on fertility. A decreased ovarian reserve is 1 of the factors assumed to be involved in fertility impairment. AMH (anti-Müllerian hormone) is currently considered the best measure of ovarian reserve.A total of 21 females with myotonic dystrophy type 1 (MD1), 25 females with myotonic dystrophy type 2 (MD2), 12 females with facioscapulohumeral muscular dystrophy (FSHD), 12 female carriers of Duchenne muscular dystrophy mutations (cDMD) and 86 age-matched healthy controls of reproductive age (range 18 - 44 years) were included in this case control study. An enzymatically amplified 2-site immunoassay was used to measure serum AMH level.The MD1 group shows a significant decrease of AMH values (median 0.7 ng/mL; range 0 - 4.9 ng/mL) compared with age-matched healthy controls (P < .01). AMH levels were similar between patients and controls in terms of females with MD2 (P = .98), FSHD (P = .55) and cDMD (P = .60).This study suggests decreased ovarian reserve in women with MD1, but not in MD2, FSHD and cDMD.

To assess subclinical cardiac function impairment in Duchenne dystrophy (DMD) female carriers. Forty-four female subjects proved as DMD carriers underwent echocardiographic examination including tissue Doppler imaging (TDI) of mitral and tricuspid annulus. Seventeen age-matched healthy female subjects served as controls. A significant differences in peak systolic annular velocity (Sa) between carriers and controls were found for lateral and septal part of the mitral annulus and for tricuspid annulus (0.09 vs. 0.11 m/s, p < 0.001, 0.08 vs. 0.09 m/s, p < 0.01 and 0.13 vs. 0.14 m/s, p = 0.02 respectively). There was also difference in early diastolic velocity (Ea) of the septal part of the mitral annulus (0.11 vs. 0.13 m/s, p = 0.03). The subclinical deterioration of systolic function is presented even in asymptomatic DMD female carriers.
