Insights

Enzyme replacement therapy improved hemoglobin and height in children with Gaucher disease, with significant reductions in liver and spleen size. Many mildly affected patients identified through screening did not require treatment.

Area of Science:

  • Pediatric Endocrinology
  • Lysosomal Storage Disorders
  • Gaucher Disease Management

Background:

  • Non-neuronopathic Gaucher disease (GD3) is a rare genetic disorder affecting children.
  • Key clinical manifestations include massive splenomegaly and growth retardation.
  • Understanding the long-term course and treatment efficacy in pediatric GD3 is crucial.

Purpose of the Study:

  • To describe the clinical course of non-neuronopathic Gaucher disease in children.
  • To evaluate the impact of enzyme replacement therapy (ERT) on disease progression.
  • To identify factors influencing treatment requirements and outcomes in pediatric GD3.

Main Methods:

  • Retrospective analysis of 56 children with non-neuronopathic Gaucher disease.
  • Patients presented before 16 years of age and were followed for 3-9 years.
  • Data collected included clinical parameters, splenomegaly, height, and treatment status.

Main Results:

  • ERT significantly increased hemoglobin levels and height z-scores in treated children.
  • Significant reductions in liver and spleen volumes were observed with ERT.
  • Platelet counts showed divergent trends; splenectomy and lung involvement were avoided.

Conclusions:

  • Enzyme replacement therapy is effective in managing key clinical features of pediatric non-neuronopathic Gaucher disease.
  • ERT leads to improved hematological parameters, growth, and organ volume reduction.
  • Mildly affected patients, often identified via screening, may not require immediate treatment.

Lysosomal Hydrolases01:22

Lysosomal Hydrolases

Lysosomes are the site for the degradation of macromolecules and biological polymers released during membrane trafficking events such as secretory, endocytic, autophagic, and phagocytic pathways. The membrane-enclosed area of the lysosome, called the lumen, contains hydrolytic enzymes active in an acidic environment. These acid hydrolases are functional at a pH between 4.5 and 5 and are involved in cellular processes such as cell signaling, energy metabolism, restoration of the plasma membrane,...
Inborn Errors of Metabolism01:20

Inborn Errors of Metabolism

Phenylketonuria (PKU) is a protein metabolism disorder characterized by high blood levels of the amino acid phenylalanine. This results from a mutation in the gene responsible for phenylalanine hydroxylase, an enzyme that converts phenylalanine into tyrosine. When this enzyme is deficient, phenylalanine builds up in the blood, leading to symptoms such as vomiting, rashes, seizures, growth deficiency, and severe mental retardation. An early diagnosis and a diet restricting phenylalanine intake...
Gene Therapy01:22

Gene Therapy

Gene therapy is a technique where a gene is inserted into a person’s cells to prevent or treat a serious disease. The added gene may be a healthy version of the gene that is mutated in the patient, or it could be a different gene that inactivates or compensates for the patient’s disease-causing gene. For example, in patients with severe combined immunodeficiency (SCID) due to a mutation in the gene for the enzyme adenosine deaminase, a functioning version of the gene can be inserted. The...

Type I Diabetes I: Introduction

Type 1 diabetes mellitus is a chronic metabolic disorder characterized by an absolute deficiency of insulin resulting from the autoimmune destruction of pancreatic β-cells. Although it can occur at any age, it is most commonly diagnosed in childhood, adolescence, or early adulthood. The loss of insulin production impairs cellular glucose uptake, resulting in persistent hyperglycemia and necessitating lifelong insulin therapy.Autoimmune Destruction of β-CellsThe hallmark of type 1 diabetes is an...
Glucose Transporters01:27

Glucose Transporters

Glucose transporters facilitate the transport of glucose across the cell membrane. In addition to glucose, some glucose transporters can also aid the movement of other hexoses such as fructose, mannose, and galactose.
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:
Jaundice01:25

Jaundice

Jaundice, or icterus, is the yellow discoloration of the skin, sclerae, and mucous membranes. It happens when plasma bilirubin levels rise above 2.5-3 mg/dL, leading to bilirubin deposition in tissue.Bilirubin is a byproduct of hemoglobin degradation. In macrophages, hemoglobin breaks down into globin and heme. Globin is converted into amino acids, while heme is turned into biliverdin by heme oxygenase, which is then reduced to unconjugated bilirubin by biliverdin reductase.Unconjugated...
