Insights

Adherence to immunosuppressive medication is a major challenge for pediatric kidney transplant recipients. This review overviews effective, sustainable interventions to improve medication adherence in these young patients.

Area of Science:

  • Pediatric Nephrology
  • Transplantation Immunology
  • Adherence Research

Background:

  • Medication adherence is critical for long-term graft survival in pediatric kidney transplant recipients.
  • Nonadherence presents a significant and persistent challenge in this population.
  • Previous research, including foundational work by Dr. Fine over 45 years ago, has sought to understand and address nonadherence.

Purpose of the Study:

  • To provide a comprehensive review of adherence-enhancing interventions for pediatric kidney transplantation.
  • To focus on strategies that are effective, clinically embeddable, and sustainable.
  • To discuss pre-transplant interventions and retransplantation decisions for patients with nonadherence-induced graft loss.

Main Methods:

  • Comprehensive literature review of adherence-enhancing interventions.
  • Analysis of strategies for identifying patients needing support.
  • Discussion of timing and decision-making for interventions and retransplantation.

Main Results:

  • Identified various adherence-enhancing interventions applicable to pediatric kidney transplant recipients.
  • Highlighted the importance of early and ongoing support.
  • Provided guidance on managing nonadherence-induced graft loss and retransplantation.

Conclusions:

  • Effective and sustainable interventions are crucial to overcome nonadherence in pediatric kidney transplantation.
  • A multi-faceted approach, including pre-transplant interventions and careful retransplantation considerations, is necessary.
  • Improving adherence can significantly impact graft survival and patient outcomes.

Renal Failure: Dose Adjustments01:11

Renal Failure: Dose Adjustments

In patients with renal impairment, drugs undergo significant changes in their pharmacokinetics, which require dosage adjustments to ensure safe and effective therapy.
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
However, dosage adjustments...

Factors Affecting Renal Clearance: Renal Impairment01:17

Factors Affecting Renal Clearance: Renal Impairment

Renal dysfunction significantly impairs the renal clearance of drugs, leading to potential complications in drug therapy. Renal failure, which can be caused by various factors, poses a significant challenge in the elimination of drugs from the body.
One condition associated with renal failure is uremia. Uremia is characterized by impaired glomerular filtration and fluid accumulation in the body. This condition hinders the renal clearance of drugs, resulting in drug accumulation and potential...

Drug Therapy

The advent of drug therapy has profoundly shaped modern mental health care, providing targeted treatments for a range of psychological disorders. Psychotherapeutic drugs, classified into antianxiety, antidepressant, and antipsychotic medications, address symptoms across anxiety disorders, mood disorders, and schizophrenia. While these medications have transformed patient outcomes, they require careful management due to their potential side effects and limitations.

Drug Elimination by Renal Route: Tubular Secretion01:15

Drug Elimination by Renal Route: Tubular Secretion

Once the process of glomerular filtration is completed, blood carrying unfiltered drug molecules traverses through efferent arterioles and makes its way into the peritubular capillaries in the proximal tubule. A variety of carriers play a pivotal role in actively secreting drugs from these peritubular capillaries into the tubular fluid. The organic anion transporter transfers acidic drugs, against an electrochemical gradient, from the peritubular capillaries into the renal tubule cells and...

Renal Drug Excretion: Tubular Secretion01:28

Renal Drug Excretion: Tubular Secretion

Active tubular secretion is a robust, energy-demanding process that utilizes carrier systems to transport drugs into renal tubules. The active renal secretion systems include the organic anion transporter (OAT) for weak acids and the organic cation transporter (OCT) for weak bases. Structurally similar drugs can compete for the same transporter, potentially leading to drug accumulation and toxicity. However, this principle can be exploited therapeutically. One example is probenecid (Probalan),...

Renal Drug Excretion: Tubular Reabsorption01:25

Renal Drug Excretion: Tubular Reabsorption

Tubular reabsorption, a process occurring post-glomerular filtration of drugs in the renal tubule, is a critical determinant of drug half-life. During the process of renal excretion, as the glomerular filtrate progresses to the distal convoluted tubule (DCT), drugs that are highly permeable, lipophilic, and nonionized undergo passive reabsorption from the tubular fluid into the surrounding peritubular capillaries. This reabsorption process restricts their elimination through the kidneys. This...
