glycogen storage disease/potassium

The results of immunochemical studies performed in 6 cases of type II glycogenosis (1 classical form, Pompe's disease) and 5 atypical forms (2 juvenile, 3 adult) are reported. The use of antiacid alpha-1,4-glucosidase antibodies greatly improved the specificity of the diagnostic tests for type II

We observed the development of generalized amyloidosis in a girl with glycogen storage disease type Ib (GSD-Ib) who showed neutropenia, neutrophil dysfunction and recurrent infections. Renal and thyroid biopsies showed secondary amyloidosis, characterized by the presence of potassium permanganate

A 36-year-old man was admitted to hospital due to right flank pain as a result of ureteral stones. He had been followed up for type 1 glycogen storage disease since the age of 11 years. He had four episodes of spontaneous stone birth during the previous 2 years, and each stone was composed mainly of

Exertional fatigue early in exercise is a clinical hallmark of muscle glycogenoses, which is often coupled with painful muscle contractures and episodes of myoglobinuria. A fundamental biochemical problem in these conditions is the impaired generation of ATP to fuel muscle contractions, which

The basis for life is the ability of the cell to maintain ion gradients across biological membranes. Such gradients are created by specific membrane-bound ion pumps [adenosine triphosphatases (ATPases)]. According to physicochemical rules passive forces equilibrate (dissipate) ion gradients. The

Fanconi-Bickel syndrome is a rare autosomal recessive disorder characterized by hepatorenal glycogen accumulation, proximal renal tubular dysfunction and impaired utilization of glucose and galactose. Most cases have been reported from Europe, Japan, Turkey and the Mediterranean belt. We report a

The Fanconi-Bickel syndrome is characterized by tubular dysfunction, impaired metabolism of glucose and galactose and glycogenosis. Up to now the data of nineteen patients have been reported. In the following case firstly an abnormal body composition is described measuring the concentration of

Metabolic cardiomyopathies include amino acid, lipid and mitochondrial disorders, as well as storage diseases. A number of metabolic disorders are associated with both myopathy and cardiomyopathy. These include the glycogen storage diseases, ie, acid maltase deficiency (infantile, childhood, and
