Pompe disease is an autosomal recessive, progressive, debilitating, and often fatal neuromuscular disorder caused by deficiency of lysosomal acid α-glucosidase (GAA). It is characterized by the accumulation of glycogen in muscle tissue that leads to progressive muscle weakness and loss of function. It presents as a broad spectrum of clinical phenotypes, with varying rates of progression, sympto...

Pregnancy in Pompe disease is still a rare event. Only few reports have been published. Physiological changes of pregnancy may be aggravated by Pompe disease or vice versa. Both may pose a risk for the mother and the unborn child. This talk outlines physiological changes of the cardiovascular, respiratory and hormonal system during pregnancy and delineates the impact on a 36-year-old Pompe pati...

s S46 patients will be captured. More investigation into the willingness of these clinics to participate in the CNDR is required. Some evidence exists that incorporation of Pompe disease into the registry might help to facilitate improved relationships between the genetic, metabolic, and specialty neuromuscular clinics across Canada, which may have important impacts beyond the Pompe disease aud...

Pompe disease is a rare autosomal recessive muscle lysosomal glycogenosis, characterised by limb-girdle muscle weakness and frequent respiratory involvement. The French Pompe registry was created in 2004 with the initial aim of studying the natural history of French patients with adult Pompe disease. Since the marketing in 2006 of enzyme replacement therapy (alglucosidase alfa, Myozyme(®)), the...

CONTEXT Bone fragility and low bone mass have been reported in small case series of patients with Pompe disease with severely reduced muscle strength or immobilization. OBJECTIVE Our objective was to determine the prevalence of morphometric vertebral fractures and to evaluate bone mass in adults with late-onset Pompe disease. DESIGN We conducted a multicenter cross-sectional observational s...

Pompe disease is a lysosomal storage disorder associated with systemic deficiency of acid α-glucosidase (GAA). Respiratory-related problems in Pompe disease include hypoventilation and upper airway dysfunction. Although these problems have generally been attributed to muscular pathology, recent work has highlighted the potential role of central nervous system (CNS) neuropathology in Pompe motor...

Pompe disease is a rare disorder producing muscle weakness and progressive impairments in performing daily motor activities, such as walking and standing. Most studies have focused on dysfunctions at cellular level, restricting the examination of gross motor functions to qualitative or subjective rating scales evaluations. With the aim of providing an instrumented quantification of upright stan...

Pompe disease is an autosomal recessive condition with an incidence of around 1 in 40,000 in the general population, and is caused by a deficiency of the enzyme acid alphaglucosidase. Clinical features occur due to the deposition and accumulation of glycogen within lysosomes, most notably those within the cardiac and skeletal muscles. The extent of this enzyme deficiency affects both the age of...

Pompe disease is an autosomal recessive disorder caused by a deficiency of acid α-glucosidase (GAA), an enzyme responsible for hydrolyzing lysosomal glycogen. Deficiency of GAA leads to systemic glycogen accumulation in the lysosomes of skeletal muscle, motor neurons, and smooth muscle. Skeletal muscle and motor neuron pathology are known to contribute to respiratory insufficiency in Pompe dise...

Pompe disease is an autosomal recessive disorder and is caused by a deficiency in acid alpha-glucosidase (GAA). A broad range of studies have been performed on Pompe patients from different countries. However, the clinical course and molecular basis of the disease in Mainland China have not been well defined. In the present study, we examined a total of 18 Chinese children with infantile-onset ...
