BACKGROUND
Pompe disease is a hereditary metabolic myopathy, for which enzyme replacement therapy (ERT) has been available since 2006. We investigated whether ERT reduces fatigue in adult patients with Pompe disease.
METHODS
In this prospective international observational survey, we used the Fatigue
We present a case of adult Pompe disease (acid maltase deficiency) with an uncommon clinical presentation characterized by severe fatigue and myalgia prior to the onset of limb girdle weakness. Remarkably, the muscle biopsy demonstrated selective involvement of type 1 muscle fibers. The cause and
Late-onset Pompe disease is an inherited metabolic myopathy with low activity of alpha glucosidase and variable clinical symptoms. In this case report we describe a woman with long standing muscular fatigue and malaise with the diagnosis initially established by pathologic findings in the muscle
BACKGROUND
Pompe disease is a progressive and debilitating autossomal recessive myopathy due to mutations in lysossomal acid-α-glucosidase. Its late-onset form has a heterogeneous presentation mimicking other neuromuscular diseases, leading to diagnostic challenge.
OBJECTIVE
To develop consensus
BACKGROUND
Adult-onset acid maltase deficiency myopathy is a rare lysosomal storage disease with an autosomal recessive pattern of inheritance. The disease can be manifested with respiratory insufficiency and fatigue.
METHODS
A case of a 45-year-old male patient is presented, and difficulty in
Late-onset Pompe disease (LOPD) is a rare genetic disorder due to the absence or deficiency of acid alpha-glucosidase enzyme resulting in slowly progressing reduction of muscle strength, causing difficulties with mobility and respiration. Wearable technologies offer novel options to evaluate
Although the adult form of acid maltase deficiency is characterized by weakness of the limb girdle muscles, weakness of the respiratory muscles out of proportion to that of the limb muscles may make the diagnosis less obvious. We present four patients aged 35 to 57 with respiratory muscle weakness
A 60-year-old woman with chronic progressive fatigue, diurnal somnolence, proximal muscle weakness, and dyspnea developed acute respiratory failure when given supplemental oxygen. Hypoventilation secondary to neuromuscular dysfunction was suspected by the critical care specialist. Neurologic
BACKGROUND
Although not curative, enzyme replacement therapy (ERT) with recombinant human acid alpha-glucosidase enzyme has shown to be effective in the treatment of late-onset Pompe disease (LOPD). For this potentially life-long treatment, little is known on the clinical effect of cessation and
Homozygosity for the common Caucasian splice site mutation c.-32-13T>G in intron 1 of the GAA gene is rather rare in Pompe patients. We report on the clinical, biochemical, morphological, muscle imaging, and genetic findings of six adult Pompe patients from five unrelated families with the
OBJECTIVE
In Pompe disease, a deficiency of acid α-glucosidase enzyme activity leads to pathologic accumulation of glycogen in tissues. Phenotype heterogeneity in Pompe includes an infantile form and late-onset forms (juvenile- and adult-onset forms). Symptoms common to all phenotypes include
Glycogen storage disease type II (GSD II) is an inherited progressive muscle disease in which lack of functional acid alpha-glucosidase (AGLU) results in lysosomal accumulation of glycogen. We report on the impact of a null mutation of the acid alpha-glucosidase gene (AGLU(-/-)) in mice on the force
A 46-year-old white female was admitted for decompensated cor pulmonale (CP). It had not interfered with her daily activities and she had not experienced shortness of breath, fatigue or muscle weakness prior to the onset of right heart failure. A thorough investigation revealed severe generalized
Pompe's disease is an autosomal recessive myopathy. The characteristic lysosomal storage of glycogen is caused by acid alpha-glucosidase deficiency. Patients with late-onset Pompe's disease present with progressive muscle weakness also affecting pulmonary function. In search of a treatment, we
Late-onset Pompe's disease (acid maltase deficiency, glycogen storage disease type II) is a slowly progressive myopathy caused by deficiency of acid alpha-glucosidase. Current developments in enzyme replacement therapy require detailed knowledge of the kind and severity of symptoms and the natural
