Insights

Low plasma levels of vitamin C and vitamin E are linked to severe neonatal hyperbilirubinemia in full-term infants. These findings highlight the importance of antioxidant status in newborn jaundice management.

Area of Science:

  • Neonatology
  • Biochemistry
  • Pediatric Nutrition

Background:

  • Neonatal hyperbilirubinemia is a common condition in newborns.
  • Antioxidant systems may play a role in the development and severity of neonatal jaundice.
  • Glucose-6-phosphate dehydrogenase (G6PD) activity is crucial for red blood cell protection.

Purpose of the Study:

  • To investigate the association between plasma vitamin E and C levels and the severity of hyperbilirubinemia.
  • To examine this relationship in full-term neonates with normal G6PD activity.

Main Methods:

  • A cohort of 130 full-term neonates with normal G6PD activity was studied.
  • Plasma levels of total bilirubin, vitamin E, and vitamin C were measured on day one of life.
  • Routine blood analyses, including hemoglobin and hematocrit, were performed.

Main Results:

  • Neonates with significant hyperbilirubinemia had markedly lower plasma vitamin C (P=0.0001) and vitamin E (P=0.001) levels compared to those without.
  • Lower hemoglobin and hematocrit levels were also observed in neonates with hyperbilirubinemia.
  • No significant differences in gestational age or birth weight were found between groups.

Conclusions:

  • Low plasma concentrations of vitamins C and E are significantly associated with increased severity of hyperbilirubinemia in term newborns.
  • These findings suggest a potential role for antioxidant vitamins in preventing or managing neonatal jaundice.

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...
Vitamins01:30

Vitamins

Vitamins, derived from the Latin word for life, are essential organic substances required in small quantities for optimal growth and overall well-being. Unlike other organic nutrients, vitamins don't act as sources of energy or building materials but rather facilitate these nutrients' utilization by the body. Vitamins are predominantly coenzymes, assisting enzymes in specific chemical actions, like the oxidation of glucose for energy involving B vitamins. Most vitamins are not produced in our...

Pharmacokinetics in Pediatric Patients: Drug Metabolism

In pediatric care, understanding the nuances of hepatic drug metabolism is crucial, as it significantly differs from that of adults. This divergence is primarily due to the developmental stage of drug-metabolizing enzymes, which affects how medications are processed in the body. In neonates, for instance, the activity of Phase I enzymes—critical for the initial breakdown of drugs—is markedly reduced, functioning at just 20–40% of the levels seen in adults. This reduction poses a challenge in...

Pharmacokinetics in Pediatric Patients: Overview and Drug Absorption

Understanding the physiological differences in the pediatric population is crucial for effective pharmacotherapy. Neonates, infants, and children exhibit significant variations in gastric pH, gastric emptying time, intestinal transit time, and biliary function. These variations profoundly affect oral drug absorption, necessitating a nuanced approach to pediatric dosing.Neonates present with a unique physiological profile, having a gastric pH greater than 4 and faster and more irregular gastric...
Radical Autoxidation01:20

Radical Autoxidation

The oxidation of an organic compound in the presence of air or oxygen is called autoxidation. For example, cumene reacts with oxygen to form hydroperoxide. Autoxidation involves initiation, propagation, and termination steps. Many organic compounds are susceptible to autoxidation—especially ethers in the presence of oxygen, which form hydroperoxides. Even though this reaction is slow, old ether bottles contain small amounts of peroxide, which leads to laboratory explosions during ether...
