Inspiratory Muscle Training (IMT) in Adult People With Pompe Disease
Glycogen Storage Disease Type IIPompe Disease (Late-onset)The goal of this multicentre, randomized and controlled cross-over trial is to evaluate the efficacy of a programme of Inspiratory Muscle Training in subjects with Late On-set Pompe Disease (LOPD). The main question is to: verify changes in Forced Vital Capacity, Postural Drop, Maximal Inspiratory Pressure, Maximal Expiratory Pressure, Peak expiratory cough pressure, Maximal Inspiratory Capacity, six- minute walk test and or 6-minute pegboard ring test.- measure changes in some questionnaries investigating dispnoea and quality of life (Short-Form 36, Individualized-Neuromuscular-Quality-of-Life, Maugeri-Respiratory-Failure 28, Borg scale, Dispnoea 12, Mulditimensional Dispnea Profile, modified Medical Research Council, Fatigue Severity Scale, Epsworth Scale, Visual Analogue Scale). Measurement will take place at baseline and after one, three, four, six and twelve months. Participants will undergo a specific treatment consisting of aerobic exercise and Inspiratory Muscle Training with Powerbreathe device or Air-Stacking. Researchers will study if Powerbreathe device is more effective than Air-stacking maneuvres

MSOT in Pompe Disease
Pompe DiseasePompe Disease (Late-onset)2 moreIn patients with Pompe disease (PD) a progressive abnormal lysosomal glycogen storage in muscle tissue leads to impaired muscle function and to degeneration of muscle fibers. Children and adults with PD present with limb-girdle muscular weakness, diaphragm weakness and impaired breathing ability. Further, patients with classic infantile PD suffer from hypertrophic cardiomyopathy. To date, the muscle pathology and the extent of the disease can be assessed using invasive techniques (e.g., muscle biopsies) or imaging (e.g., MRI). These techniques are time consuming, and especially in young patients, require anesthesia, which increases the acute risk of respiratory failure. Multispectral optoacoustic tomography (MSOT) allows the detection of specific endogenous chromophores like collagen, myoglobin or hemoglobin by using a non-invasive approach comparable to conventional ultrasound. Instead of sound waves, MSOT illuminates tissue with near-infrared light of transient energy, which is absorbed and results in thermo-elastic expansion of certain molecules. This expansion generates ultrasound waves that are detected by the same device. Multispectral illumination and unmixing then allows the precise localisation and quantification of muscle-specific subcellular structures. MSOT has already been demonstrated the potential to visualize the muscular structure and the clinical extent of muscular disease in patients with Duchenne muscle dystrophy and differentiates those patients from healthy volunteers. The aim of the study is to establish glycogen as a novel PD-specific imaging target using MSOT-imaging. It intends to identify a PD-specific muscle pathology-signature by quantification of already established targets (collagen, myoglobin, hemoglobin, glycogen if applicable). This signature will aid in differentiating PD from other muscular pathologies and healthy volunteers and will ultimately serve as a potential non-invasive monitoring biomarker.
