Neonatal jaundice and glucose-6-phosphate dehydrogenase deficiency in Basrah

Insights

Glucose-6-Phosphate Dehydrogenase (G6PD) deficiency is common in newborns with jaundice. This red cell defect significantly increases the risk of severe hyperbilirubinaemia and kernicterus.

Area of Science:

  • Neonatal Medicine
  • Hematology
  • Genetics

Background:

  • Neonatal jaundice is a common clinical presentation in newborns.
  • Erythrocyte glucose-6-phosphate dehydrogenase (G6PD) deficiency is a prevalent genetic disorder.
  • G6PD deficiency is associated with hemolytic anemia and hyperbilirubinemia.

Purpose of the Study:

  • To investigate the association between G6PD deficiency and severe hyperbilirubinaemia in jaundiced newborns.
  • To determine the incidence of G6PD deficiency in this population.
  • To evaluate the impact of G6PD deficiency on the severity of neonatal jaundice and outcomes.

Main Methods:

  • A study was conducted on 186 newborn babies presenting with jaundice.
  • Erythrocyte G6PD deficiency was detected in the participants.
  • Incidence of severe hyperbilirubinaemia and need for exchange transfusion were recorded.

Main Results:

  • G6PD deficiency was detected in 51% of the jaundiced newborns.
  • Severe hyperbilirubinaemia was significantly more frequent in G6PD-deficient infants (46%) compared to non-deficient infants (15%).
  • Phototherapy did not decrease the need for exchange transfusion; 27 infants required it, and 8 developed kernicterus.

Conclusions:

  • G6PD deficiency is a significant risk factor for severe neonatal jaundice and kernicterus in Basrah.
  • Early detection and close monitoring of G6PD-deficient newborns are crucial.
  • Interventions should be tailored to reduce the risk of severe outcomes in affected infants.

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:
Diseases of the Liver and Gallbladder01:26

Diseases of the Liver and Gallbladder

Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not related to...
Overview of Protein Metabolism01:21

Overview of Protein Metabolism

Proteins are broken down into amino acids during digestion. Unlike fats and carbohydrates, which are stored for later use, proteins are not. Instead, amino acids are either used to produce ATP through oxidation or contribute to the creation of new proteins for the growth and repair of the body. Any surplus amino acids from the diet are converted into glucose or triglycerides rather than excreted.
Amino acids play various roles in the body once they are absorbed into cells. They are restructured...
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...
Pathophysiology of Diabetes01:20

Pathophysiology of Diabetes

Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility, suggesting a...
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...
