Insights

Icodextrin fluid removal in pediatric automated peritoneal dialysis (APD) patients showed significant age correlation. Young children may experience Icodextrin re-absorption, impacting treatment efficacy.

Area of Science:

  • Pediatric Nephrology
  • Renal Replacement Therapy

Background:

  • Limited data exists on Icodextrin use in pediatric patients.
  • Previous assumptions suggested age-independent Icodextrin characteristics.

Purpose of the Study:

  • To evaluate Icodextrin ultrafiltration in a cohort of young pediatric automated peritoneal dialysis (APD) patients.
  • To investigate potential age-related differences in Icodextrin behavior.

Main Methods:

  • Calculated net Icodextrin daytime dwell ultrafiltration (ml/h/m2) in pediatric APD patients.
  • Analyzed fluid removal in relation to patient age and peritoneal equilibration test (PET) results.

Main Results:

  • Half of the patients exhibited Icodextrin re-absorption, even with reduced dwell times.
  • Re-absorption was observed in all four patients on cyclic nocturnal APD, three of whom were high transporters.
  • Icodextrin fluid removal significantly correlated with patient age (Spearman rank r=0.8571, P=0.0107).

Conclusions:

  • Icodextrin appears to behave differently in young pediatric patients compared to older individuals.
  • Age is a significant factor influencing Icodextrin efficacy in pediatric APD.
  • Further research is needed to optimize Icodextrin use in this population.

Peritoneal Dialysis I: Introduction and Procedure

Peritoneal dialysis (PD) is a procedure that facilitates the exchange of solutes, waste products, electrolytes, and excess fluid between the blood in the peritoneal capillaries and a dialysis solution introduced into the peritoneal cavity.Principles of Peritoneal Dialysis (PD)Diffusion: Waste products such as urea and electrolytes move from high concentrations in the blood to low concentrations in the dialysate across the peritoneal membrane. This mechanism is driven by the concentration...

Pharmacokinetics in Pediatric Patients: Drug Excretion

In pediatric medicine, understanding the renal function and drug elimination nuances is crucial for administering safe and effective treatments. Newborns, in particular, display markedly slower renal functions than adults, profoundly affecting how drugs are cleared from their bodies. This slower drug clearance requires clinicians to extend the dosing intervals for many medications to prevent drug accumulation and toxicity while ensuring therapeutic efficacy.One key area where these adjustments...

Drug Dosing: Infants and Children

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

Dialysis

Dialysis is a diffusion-based purification process that separates analyte molecules from a complex matrix. This is accomplished by allowing molecules in the solution to pass through a semipermeable membrane into a liquid on the other side. The membrane is usually made of cellulose acetate or cellulose nitrate, and the second liquid must be miscible with the solution. Ions (e.g., chloride or sodium) or organic molecules (e.g., glucose) can pass through the membrane pores, which generally have...

Dialysis

Renal failure occurs when the kidneys lose their ability to filter waste products from the blood effectively. It can be classified into two types: acute renal failure (ARF) and chronic renal failure (CRF).
Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...

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...
