INTRODUCTION: Infantile-onset Pompe disease is a kind of glycogenosis resulting from a deficit of the enzyme acid alpha-glucosidase. Before specific enzyme replacement therapy (ERT) became available, the classic form was fatal during the first two years of life. ERT increases survival and improves cardiac, respiratory and motor functioning. CASE REPORTS: Case 1: 2-month-old infant with predominantly axial hypotonia who required the use of a nasogastric tube as a result of difficulties in sucking and swallowing...

INTRODUCTION: Pulmonary interstitial glycogenosis (PIG) is an idiopathic lung condition that remains clinically underrecognized despite a growing body of literature. CASE REPORT: We present a case of PIG with pulmonary hypertension without underlying cardiac disease. This patient presented with respiratory distress and spontaneous pneumothorax at 6 months of age. Laboratory and imaging investigations demonstrated nonspecific features, but refractory pulmonary hypertension was confirmed on cardiac catheterization...

OBJECTIVES: Based on studies with hepatorenal syndrome, it is widely regarded that renal function is impacted in chronic liver disease. Therefore we investigated renal function in our children with chronic liver disease. METHODS: In a retrospective study of 277 children with chronic liver disease, renal function was investigated as glomerular filtration rate (GFR) and effective renal plasma flow (ERPF), measured as clearance of inulin and para-amino hippuric acid or clearance of iohexol...

Hepatomegaly and elevated liver enzymes in patients with diabetes are commonly associated with fatty liver disease. However, physicians often forget about another intrinsic substance that can cause a similar clinical picture-glycogen. Liver stores approximately one third of the total body glycogen and is responsible for blood glucose homeostasis. Excessive hepatocellular glycogen accumulation occurs not only in congenital glycogen storage diseases, but also in acquired conditions associated with hyperglycemic-hyperinsulinemic states such as uncontrolled diabetes mellitus, high-dose corticosteroid use, and dumping syndrome...

Glycogen storage disease (GSD) is an inherited metabolic disorder characterized by early childhood lipid metabolic disturbances with potentially proatherogenic effects. The review outlines the characteristics of impaired lipid composition and other changes in the cardiovascular system in GSD types I and III. It analyzes the factors enabling and inhibiting the development of atherosclerosis in patients with GSD. The review describes the paradox of vascular resistance to the development of early atherosclerosis despite the proatherogenic composition of lipids in the patients of this group...

Primary or isolated pulmonary interstitial glycogenosis (PIG) is a rare disease presenting as tachypnea and hypoxemia during the perinatal period. A diffuse interstitial infiltrate with focal hyperinflation is visible on chest imaging. The biopsy findings include diffuse expansion of the interstitium by spindle-shaped cells with pale cytoplasm that, on electron microscopy (EM), are poorly differentiated mesenchymal cells containing abundant monoparticulate glycogen. This glycogenosis appears to be a transient abnormality, usually with a favorable prognosis...

INTRODUCTION: Phosphoglucomutase 1 deficiency (PGM1 deficiency) has been identified as both, glycogenosis and congenital disorder of glycosylation (CDG). The phenotype includes hepatopathy, myopathy, oropharyngeal malformations, heart disease and growth retardation. Oral galactose supplementation at a dosage of 1 g per kg body weight per day is regarded as the therapy of choice. RESULTS: We report on a patient with a novel disease causing mutation, who was treated for 1...

We report on the detection of discordant inclusions in the brain of a 25-week female fetus with a very rare lysosomal storage disease, namely, Sly disease (mucopolysaccharidosis (MPS) type VII), presenting with nonimmune hydrops fetalis. Besides vacuolated neurons, we found abundant deposition of polyglucosan bodies (PGBs) in the developing brain of this fetus in whom MPS-VII was corroborated by lysosomal beta-glucuronidase-deficiency detected in fetal blood and fetal skin-fibroblasts and by the presence of a heterozygous pathogenic variant in the GUSB gene in the mother...

PURPOSE OF REVIEW: The field of muscle glycogenoses has progressed in recent years by the identification of new disorders, and by reaching a better understanding of pathophysiology of the disorders and the physiology of glycogen metabolism. RECENT FINDINGS: In this review, we describe the clinical and pathological features of the three most recently described muscle glycogenoses caused by recessive mutations in GYG1, RBCK1 and PGM1. The three involved enzymes play different roles in glycogen metabolism...

BACKGROUND: We report the ophthalmic findings of a patient with type Ia glycogen storage disease (GSD Ia), DiGeorge syndrome (DGS), cataract and optic nerve head drusen (ONHD). CASE PRESENTATION: A 26-year-old white woman, born at term by natural delivery presented with a post-natal diagnosis of GSD Ia. Genetic testing by array-comparative genomic hybridization (CGH) for DGS was required because of her low levels of serum calcium. The patient has been followed from birth, attending the day-hospital every six months at the San Paolo Hospital, Milan, outpatient clinic for metabolic diseases and previously at another eye center...

Recently, several cases of hepatic glycogenosis (HG) have been reported. García-Suárez et al. described a young female patient with poorly controlled type 1 diabetes, right upper quadrant pain and elevated serum transaminases and GGT. After other causes of liver disease were excluded and a liver biopsy was performed, the patient was diagnosed with HG. HG is rare and can be misdiagnosed as steatohepatitis. To date, less than 20 cases have been reported in adults.

OBJECTIVE: Pompe disease (glycogenosis type II) is caused by lysosomal alpha-glucosidase deficiency, which leads to a block in intra-lysosomal glycogen breakdown. In spite of enzyme replacement therapy, Pompe disease continues to be a progressive metabolic myopathy. Considering the health benefits of exercise, it is important in Pompe disease to acquire more information about muscle substrate use during exercise. METHODS: Seven adults with Pompe disease were matched to a healthy control group (1:1)...

OBJECTIVE: To determine whether known loss-of-function alleles of the acidic α-glucosidase gene (GAA) are present in the Droughtmaster breed and, if so, whether the clinical signs and pathology of generalised glycogenosis (Pompe's disease) previously reported in other affected cattle are also seen in homozygous Droughtmasters. DESIGN: Existing genomic and other diagnostic tests developed for generalised glycogenosis in cattle were used to test for the presence of the three known loss-of-function alleles of GAA in a herd of Droughtmaster cattle...

Aims: Mutations in PRKAG2, the gene encoding for the γ2 subunit of 5'-AMP-activated protein kinase (AMPK), are responsible for an autosomal dominant glycogenosis with a cardiac presentation, associating hypertrophic cardiomyopathy (HCM), ventricular pre-excitation (VPE), and progressive heart block. The aim of this study was to perform a retrospective time-to-event study of the clinical manifestations associated with PRKAG2 mutations. Methods and Results: A cohort of 34 patients from 9 families was recruited between 2001 and 2010...

Fanconi-Bickel syndrome is a rare autosomal recessive disorder due to mutations in the facilitative glucose transporter 2 ( GLUT2 or SLC2A2) gene resulting in excessive glycogen storage predominantly in the liver and kidney. Previous case reports of this condition have described liver biopsies with glycogen storage and variable steatosis and/or fibrosis. Unlike in other types of glycogen storage disease, hepatocellular adenomas and carcinomas have not been described to date in this syndrome. A 6-year-old boy with consanguineous parents had short stature, poorly controlled rickets, hepatosplenomegaly, and renal tubular dysfunction clinically consistent with Fanconi-Bickel Syndrome...

Glycogen storage disease (GSD) type IX is a rare disease of variable clinical severity affecting primarily the liver tissue. Individuals with liver phosphorylase b kinase (PhK) deficiency (GSD IX) can present with hepatomegaly with elevated serum transaminases, ketotic hypoglycemia, hyperlipidemia, and poor growth with considerable variation in clinical severity. PhK is a cAMP-dependent protein kinase that phosphorylates the inactive form of glycogen phosphorylase, phosphorylase b, to produce the active form, phosphorylase a...
