Insights

Intermittent etanercept therapy is safe and effective for pediatric psoriasis. In a 48-week study, 80% of pediatric patients maintained or regained PASI 75, with no serious adverse events reported.

Area of Science:

  • Pediatric dermatology
  • Immunology
  • Pharmacology

Background:

  • Etanercept is a well-tolerated treatment for adult psoriasis.
  • Limited data exists on intermittent etanercept use in pediatric psoriasis patients.

Purpose of the Study:

  • To evaluate the safety and efficacy of intermittent etanercept administration in children with psoriasis.
  • To assess the outcomes of a withdrawal-retreatment strategy in pediatric psoriasis.

Main Methods:

  • A 48-week study involving pediatric patients (4-17 years) with moderate to severe plaque psoriasis (PASI ≥ 12).
  • Following initial treatment, eligible patients achieving PASI 75 were re-randomized to a 12-week withdrawal (placebo) or retreatment (etanercept) period.
  • Patients receiving placebo were retreated with etanercept if PASI 75 was not maintained.

Main Results:

  • 138 patients entered the withdrawal-retreatment phase, randomized equally to placebo or etanercept.
  • 80% of patients on etanercept (blinded or open-label) maintained or regained PASI 75.
  • No serious adverse events or infections were reported; 70% of patients on blinded etanercept maintained PASI 75 throughout the 12-week period, versus 54% on placebo.

Conclusions:

  • Intermittent etanercept therapy demonstrated safety and efficacy in pediatric psoriasis over a 12-week withdrawal-retreatment period.
  • No serious adverse events or infections occurred, supporting the safety profile.
  • The efficacy was supported by 80% of patients maintaining or regaining PASI 75 on etanercept.

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: 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...

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...

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...

Treatment for Pulmonary Arterial Hypertension: Endothelin Receptor Antagonists

Endothelins (ETs) are potent vasoactive peptides critical in the human body's various physiological and pathological processes. One of the most promising therapeutic strategies for treating pulmonary arterial hypertension (PAH) involves counteracting the effects of these endothelins using a class of drugs known as endothelin receptor antagonists.
ETs are synthesized through a complex sequence of enzymatic steps, primarily involving an enzyme referred to as endothelin-converting enzyme (ECE). Of...

Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF

Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab (Humira),...
