Summary
Genetic variations impact acute lymphoblastic leukemia treatment. Pharmacogenomic data on thiopurine methyltransferase and NUDT15 variants affecting 6-mercaptopurine dosing are reviewed, highlighting the need for further research.
Area of Science:
- Pharmacogenomics
- Oncology
- Genetics
Background:
- Inherited genetic variations can influence drug sensitivity in patients with acute lymphoblastic leukemia (ALL).
- These variations may predispose individuals to adverse treatment side effects, impacting therapeutic outcomes.
- Understanding these genetic factors is crucial for optimizing ALL treatment strategies.
Purpose of the Study:
- To review available pharmacogenomic data in children and young adults with ALL.
- To emphasize clinically actionable and emerging discoveries related to genetic variations and drug response.
- To highlight the need for further pharmacogenomic research in ALL.
Main Methods:
- Literature review of existing pharmacogenomic studies in pediatric and young adult ALL.
- Focus on genetic variants affecting drug metabolism and efficacy, such as those in thiopurine methyltransferase (TPMT) and NUDT15.
- Analysis of evidence related to 6-mercaptopurine (6-MP) dosing adjustments based on genetic profiles.
Main Results:
- Genetic variants in TPMT and NUDT15 significantly alter 6-MP efficacy and toxicity.
- Clinically actionable pharmacogenomic discoveries are emerging, enabling personalized dosing strategies.
- Evidence supports the role of pharmacogenomics in managing ALL treatment-related side effects.
Conclusions:
- Pharmacogenomic data provides valuable insights into optimizing ALL therapy.
- Ongoing research is necessary to validate recent findings and explore novel therapeutic targets.
- Further studies in young adults and with new drugs are essential for future treatment advancements.

01:24Dosage Regimen: Individualization
80
Individualization in dosing regimens is the customization of medication doses for individual patients. Its necessity arises from the goal of maximizing therapeutic benefits while minimizing risks. This approach is pivotal because human responses to drugs can vary widely; what is effective for one person may be inadequate or excessive for another. Interpatient (intersubject) variability refers to differences in drug responses between individuals, while intrapatient (intrasubject) variability...

01:29Therapeutic Drug Monitoring: Affecting Factors
93
Therapeutic Drug Monitoring (TDM) is the clinical practice of measuring specific drug levels in a patient's blood or body tissues to manage and optimize therapy. TDM is crucial for drugs with narrow therapeutic windows, like warfarin and phenytoin, where incorrect doses can lead to treatment failure or severe side effects. This monitoring ensures the dosage administered is within a safe and effective range. The factors affecting therapeutic drug monitoring include:Patient-Specific Factors:a.

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

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.

When it comes to infants and young children, they are typically administered smaller doses of medication in comparison to adults. This is primarily because their organ functions still need to fully develop, meaning their bodies are not as efficient at metabolizing or eliminating drugs. Additionally, their blood-brain barrier is more permeable than in adults. As a result, high concentrations of drugs can easily penetrate the central nervous system (CNS), potentially leading to neurological...

01:01Dosage Regimens: Partial Pharmacokinetic Parameters
64
It is not uncommon for complete drug pharmacokinetic profiles to remain elusive in pharmacokinetics. This necessitates certain educated assumptions by pharmacokineticists to determine appropriate dosage regimens without comprehensive pharmacokinetic data from animal or human studies. One prevalent assumption is setting the bioavailability factor, denoted as F, to 1 or 100%. This assumption caters to the scenario where a drug doesn't achieve full systemic absorption, resulting in the patient...
