BACKGROUND Pompe disease is a progressive metabolic myopathy. Involvement of respiratory muscles leads to progressive pulmonary dysfunction, particularly in supine position. Diaphragmatic weakness is considered to be the most important component. Standard spirometry is to some extent indicative but provides too little insight into diaphragmatic dynamics. We used lung MRI to study diaphragmatic ...

Pompe disease is a lysosomal storage disorder caused by alpha-glucosidase deficiency. The disease is characterized by accumulation of glycogen in the lysosomes. The accumulation has unique ultrastructural features which enable a prenatal diagnosis by electron microscopy. We describe prenatal electron microscopic testing in a fetus of a mother whose previous child died of Pompe disease. The dise...

The patient was a 15 year-old girl who turned out at the Physical Therapy Clinic presenting progressive scoliosis and angle of 50o Coob by X-Ray. She complained of back pain, headache and weakness of shoulder and pelvic girdle. Physical therapy evaluation came across features of delayed motor development and undernourishment, together with generalized muscle weakness (grade = 4) which was obser...

Pompe disease is a systemic metabolic disorder characterized by lack of acid-alpha glucosidase (GAA) resulting in ubiquitous lysosomal glycogen accumulation. Respiratory and ambulatory dysfunction are prominent features in patients with Pompe yet the mechanism defining the development of muscle weakness is currently unclear. Transgenic animal models of Pompe disease mirroring the patient phenot...

objective: pompe disease is a rare neuromuscular genetic disorder and is classified into two forms of early and late-onset. over the past two decades, mitochondrial abnormalities have been recognized as an important contributor to an array of neuromuscular diseases. we therefore aimed to compare mitochondrial copy number and mitochondrial displacement-loop sequence variation in infantile and ad...

Pompe disease is a form of muscular dystrophy due to lysosomal storage of glycogen caused by deficiency of acid α-glucosidase (GAA). Respiratory failure in Pompe disease has been attributed to respiratory muscle dysfunction. However, evaluation of spinal tissue from Pompe patients and animal models indicates glycogen accumulation and lower motoneuron pathology. We hypothesized that restoring GA...

OBJECTIVE To describe the first case of infantile Pompe disease to be treated in Brazil. DESCRIPTION Pompe disease is a glycogen storage disease related to defects in the acid alpha-glucosidase enzyme, leading to an intracellular accumulation of glycogen, mainly in muscles. Two forms are described: infantile and juvenile. Since 2006, treatment with recombinant human acid alpha-glucosidase has...

These guidelines provide a short summary of recommendations on Pompe disease, how to diagnose this disease, management of adult patients with this disease, follow-up of the patients and recommendations on therapy and genetic testing. Early diagnosis and management of patients with Pompe disease requires a multidisciplinary approach of several different experts. These guidelines were produced by...

Pompe disease is an acid maltase deficiency being part of glycogen storage diseases that affects all age groups. In both childhood and adult forms, the classic clinical picture is that of a progressive myopathy. Respiratory muscle involvement is common, may occur early in the course of the disease, and is the most frequent cause of mortality from acid maltase deficiency. Its association with rh...

Pompe disease (acid maltase deficiency, glycogen storage disease type II) is a rare progressive autosomal recessive disorder caused by a deficiency of lysosomal hydrolase acid alpha-glucosidase. Historically, infantile-onset Pompe disease presents with cardiomegaly, hepatomegaly, weakness and hypotonia leading to death caused by cardiorespiratory failure in the first year of life. Enzyme replac...
