Background: Untreated patients affected by hereditary fructose intolerance (HFI) present an abnormal transferrin (Tf) glycosylation pattern suggestive of N-hypoglycosylation. Analysis of defects in N-glycosylation is possible by analysis of serum sialotransferrin (sialoTf) pattern. The sialoTf profile is a valuable tool to facilitate the diagnosis of HFI.

Managing Inherited Metabolic Disorders (IMDs) at risk for hypoglycemia, such as Glycogen Storage Diseases (GSDs), Hereditary Fructose Metabolism Disorders (HFMDs) and Congenital Hyperinsulinism (CH), poses challenges in dietary treatments and blood glucose monitoring. The effectiveness of Continuous Glucose Monitoring (CGM) remains a subject of ongoing debate, with IMD guidelines maintaining caution. Therefore, a systematic evaluation is needed to understand the potential benefits of CGM during dietary interventions.

Article Synopsis
  • Methylmalonic Aciduria (MA) is a rare disorder that leads to toxic methylmalonic acid buildup, causing serious health issues like metabolic crises and kidney damage.
  • A case study of a 39-year-old male with MA and stage IV chronic kidney disease illustrates how a single hemodialysis session effectively treated his acute metabolic crisis after a gastrointestinal infection.
  • Long-term management of MA often requires continuous kidney and/or liver transplantation, with combined liver-kidney transplants offering better outcomes due to reduced acid production and improved kidney function.

Background: Fabry disease (FD) is a multisystem, monogenic, X-linked storage disorder caused by mutations in the GLA gene, resulting in reduced alfa-galactosidase A enzyme activity. This effect leads to the accumulation of glycosphingolipids, particularly globotriaosylceramide, in various tissues, including the heart, kidney, vasculature, smooth muscle, and peripheral nervous system. Hemizygous males are usually more severely affected than females, in whom random inactivation of an X chromosome may lead to variable phenotype.

Gaucher disease is a lysosomal storage disorder caused by functional glucocerebrosidase enzyme deficiency. Hepatosplenomegaly and hematological complications are found in both Gaucher disease and Acid Sphingomyelinase Deficiency, which is caused by acid sphingomyelinase dysfunction. The possible overlap in clinical presentation can cause diagnostic errors in differential diagnosis.
