Insights

Newborns with undiagnosed glucose-6 phosphate dehydrogenase (G6PD) deficiency face increased kernicterus risk. Early detection and management are crucial to prevent this severe form of jaundice.

Area of Science:

  • Neonatal Medicine
  • Pediatric Hematology
  • Genetics

Background:

  • Jaundice is common in newborns, but severe cases leading to kernicterus are concerning.
  • Glucose-6 phosphate dehydrogenase (G6PD) deficiency is a known risk factor for neonatal jaundice.
  • Increasing kernicterus incidence is linked to unrecognized G6PD deficiency and early hospital discharge.

Purpose of the Study:

  • To investigate the prevalence of G6PD deficiency in neonatal kernicterus cases.
  • To review current literature on G6PD deficiency and kernicterus.
  • To suggest preventive strategies for kernicterus in high-prevalence G6PD deficiency settings.

Main Methods:

  • Retrospective case series analysis.
  • Review of recent scientific literature.
  • Clinical data compilation and analysis.

Main Results:

  • Fourteen cases of kernicterus were identified over six years.
  • G6PD deficiency was present in 71% of the kernicterus cases.
  • A high prevalence of G6PD deficiency in the study population was noted.

Conclusions:

  • Undiagnosed G6PD deficiency is a significant contributor to neonatal kernicterus.
  • Preventive measures are essential, especially in regions with high G6PD deficiency rates.
  • Enhanced screening and monitoring protocols are recommended for at-risk newborns.

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...
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...
Hepatic Encephalopathy01:29

Hepatic Encephalopathy

DefinitionHepatic encephalopathy is a reversible neurologic syndrome that results from advanced liver dysfunction or portosystemic shunting. It leads to disturbances in cognition, behavior, and motor function due to the brain’s exposure to gut-derived toxins that the liver fails to detoxify.EtiologyThis condition develops either in the setting of acute fulminant hepatitis or progressively during chronic liver disease, such as cirrhosis and portal hypertension. Portosystemic shunting—including...
Cirrhosis II: Pathophysiology01:24

Cirrhosis II: Pathophysiology

Cirrhosis is a progressive chronic liver injury caused by prolonged inflammation, excessive fibrotic remodeling, and impaired regeneration. Over time, repeated hepatic insults disrupt the liver’s architecture and function, leading to reduced blood flow, impaired bile drainage, and diminished metabolic capacity.Pathophysiology of cirrhosisCirrhosis arises from three main responses to chronic liver damage: inflammation, immune activation, and hepatocyte death. These processes lead to structural...
Photoreceptors and Visual Pathways01:22

Photoreceptors and Visual Pathways

At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category, whereas...

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...
