Insights

Neonatal intestinal failure-associated liver disease (IFALD) is more common and linked to prolonged parenteral nutrition (PN) and elevated plant sterols (PS). High PS levels, particularly stigmasterol, may contribute to IFALD in neonates.

Area of Science:

  • Pediatric Gastroenterology
  • Hepatology
  • Neonatal Nutrition

Background:

  • Intestinal failure-associated liver disease (IFALD) is a serious complication in patients receiving parenteral nutrition (PN).
  • Neonates are particularly vulnerable to IFALD due to immature organ systems and prolonged PN dependence.
  • The role of parenteral plant sterols (PS) in the pathogenesis of IFALD is not fully understood.

Purpose of the Study:

  • To evaluate the incidence of prolonged PN, IFALD, and associated complications in neonates compared to children.
  • To investigate the significance of parenteral plant sterols (PS) in neonatal IFALD.
  • To compare serum sterol profiles and liver biochemistry between neonates and children with IFALD and healthy controls.

Main Methods:

  • Prospective study of 28 neonates and 11 children with intestinal failure requiring PN.
  • Repeated measurements of serum cholesterol, noncholesterol sterols (including PS), cholestanol, cholesterol precursors, and liver biochemistry.
  • Comparison with healthy neonate and child control groups.

Main Results:

  • IFALD occurred significantly more frequently in neonates (63%) than children (27%).
  • Neonates exhibited markedly elevated serum PS (2- to 22-fold) and cholestanol compared to controls and children on PN.
  • Higher serum PS and cholestanol levels correlated with IFALD presence and PN duration; IFALD persisted in 25% of neonates post-PN.

Conclusions:

  • Neonates on PN have a higher incidence of IFALD, associated with PN duration and significantly increased serum PS, especially stigmasterol.
  • Accumulation of parenteral plant sterols appears to be a key factor contributing to IFALD in neonates.
  • These findings highlight the need for monitoring PS levels in neonates receiving prolonged PN.

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...

Inflammatory Bowel Disease I: Ulcerative Colitis

Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Pharmacokinetics in Pediatric Patients: Drug Distribution

Drug distribution in the pediatric population exhibits unique challenges and considerations due to the physiological differences between children, particularly neonates and infants, and adults. A crucial aspect of pediatric pharmacology is understanding how these differences impact the pharmacokinetics of various drugs, necessitating age-specific dosing strategies to ensure efficacy and safety.Neonates and infants have a higher total body water content, ~75%–90% of their body weight, compared...

Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test

In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess the...

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...

Esophageal Varices-II: Clinical Features and Management

Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.
In the initial assessment, a thorough review of the patient's medical history is vital to identify risk factors such as liver disease, alcohol abuse, or...
