Summary
Drug hypersensitivity reactions (DHRs) have complex genetic underpinnings. This review explores the current understanding of genetic factors in DHRs, including immune-mediated and drug-induced reactions, and suggests future research directions.
Area of Science:
- Immunology
- Pharmacology
- Genetics
- Clinical Medicine
Background:
- Drug hypersensitivity reactions (DHRs) are diverse, potentially severe clinical events influenced by both environmental and individual factors.
- Despite progress, the genetic basis of DHRs remains incompletely understood, hindering accurate prediction and management.
- Identifying genetic predispositions is crucial for understanding the heterogeneity of DHRs.
Purpose of the Study:
- To summarize current research on the genetic factors contributing to DHRs.
- To focus on immune-mediated (immediate and non-immediate) and pharmacologically mediated (NSAID cross-intolerance) DHRs.
- To propose technological approaches for elucidating DHR molecular mechanisms.
Main Methods:
- Review of existing literature on the genetics of DHRs.
- Analysis of specific types of DHRs, including immune-mediated and NSAID-related reactions.
- Discussion of potential future technological advancements for genetic research in DHRs.
Main Results:
- Current knowledge of the genetic basis of DHRs is incomplete.
- Specific immune-mediated and pharmacologically mediated reactions are highlighted.
- Technological advancements are needed to fully understand the molecular mechanisms.
Conclusions:
- A comprehensive understanding of DHR genetics requires further investigation.
- Future research should leverage advanced technologies to decipher molecular pathways.
- This review aims to inform allergists, researchers, and clinicians managing DHRs.

01:16Drug toxicity: Idiosyncratic Reactions
131
Idiosyncratic drug reactions represent abnormal chemical responses that vary significantly among individuals, ranging from extreme sensitivity to low doses to insensitivity to high doses. These reactions often occur due to the drug's covalent binding with serum proteins, forming a foreign hapten that triggers an immunotoxicological response. The variability in drug reactions has a strong pharmacogenetic foundation, with genetic differences crucial in how individuals metabolize drugs. For...

01:30Drug Toxicity: Allergic Reactions
106
Drug-related allergies are immune-mediated responses triggered by the administration of pharmacological agents. These hypersensitivity reactions are classified based on the immune mechanisms involved. The four primary types—Type I, II, III, and IV—are mediated by different immunological pathways and exhibit distinct clinical manifestations.Type I Hypersensitivity/ IgE-Mediated Reactions: Immunoglobulin E (IgE) immediately mediates Type I hypersensitivity reactions. Upon initial...

01:27Allergic Drug Reactions
1.6K
Allergic reactions related to drugs are hypersensitivity responses driven by the immune system and bear no connection to the drug's therapeutic action. While drugs in isolation do not trigger an immune response, they can interact with endogenous proteins to form antigens. These antigens stimulate lymphocytes to produce antibodies. IgE-type antibodies attach themselves to mast cells. Upon subsequent exposure to the same stimulus, the antigen-antibody interaction is initiated, unleashing...

98
Genetic variations significantly influence drug response through pharmacokinetics, receptor interactions, and biologic milieu modifications. Pharmacokinetic alterations impact drug metabolism and clearance, affecting efficacy and toxicity. Variants in drug-metabolizing enzymes, such as CYP2C9 and CYP2C19, alter drug activation and elimination. For example, CYP2C9 loss-of-function variants require lower warfarin doses to prevent excessive bleeding, while CYP2C19 variants reduce clopidogrel...

01:27Principles of Pharmacogenetics: Types of Genetic Variants
79
The human genome is over 99.9% identical between individuals, yet genetic differences exist at millions of bases. The human genome contains approximately 3 million variant positions per individual, many of which are heterozygous, contributing to genetic diversity and individual traits. Genetic variations include single-nucleotide polymorphisms (SNPs), insertions, deletions, and copy number variations (CNVs).SNPs, the most common variation, involve single-base changes in DNA. These can be...

01:29Pharmacogenetics and Pharmacogenomics: Overview
132
Pharmacogenetics and pharmacogenomics examine how genetic factors influence an individual's response to drugs. While pharmacogenetics focuses on the impact of specific genetic variants on drug effects, pharmacogenomics takes a broader approach, studying how genetic variation across populations contributes to differences in drug responses. These fields aim to explain why individuals may experience varying levels of efficacy or adverse reactions to the same medication.Variability in drug...
