Summary
Alcohol consumption and alcohol sensitivity, influenced by ALDH2 genotypes, are significant risk factors for periodontitis progression. Higher alcohol intake increases the risk, especially for individuals with specific ALDH2 genotypes.
Area of Science:
- Genetics and Genomics
- Periodontology
- Toxicology
Background:
- Periodontitis progression may be linked to ALDH2 genotypes affecting acetaldehyde metabolism.
- Acetaldehyde accumulation due to impaired oxidation can lead to toxic effects.
Purpose of the Study:
- To investigate the association between ALDH2 genotypes, alcohol consumption, and periodontitis progression.
- To determine if alcohol sensitivity modifies the risk of periodontitis progression.
Main Methods:
- Prospective cohort study analyzing 183 individuals with complete data.
- Evaluation of periodontitis progression using probing pocket depth measurements.
- Assessment of alcohol consumption and ALDH2 genotypes (ALDH2 *1/*1 and ALDH2 *1/*2).
Main Results:
- Individuals consuming >= 33.0 g/day of alcohol showed a higher risk of periodontitis progression (OR = 3.54).
- ALDH2 *1/*2 individuals consuming >= 33 g/day of alcohol had a significantly increased risk (OR = 4.28) compared to ALDH2 *1/*1 individuals.
- Alcohol consumption and sensitivity emerged as potential risk factors for periodontitis progression.
Conclusions:
- Alcohol consumption is a risk factor for periodontitis progression.
- Alcohol sensitivity, determined by ALDH2 genotype, may further elevate the risk.
- Findings suggest a complex interplay between genetics, alcohol intake, and periodontal health.

01:27Pharmacogenetics of Phase II Enzymes: N-acetyltransferase, Thiopurine S-methyltransferase, UDP-glucuronosyltransferase
Phase II biotransformation reactions are essential for detoxifying and eliminating xenobiotics, including many pharmaceutical compounds. These reactions typically involve conjugation, the covalent attachment of polar endogenous groups such as glucuronic acid, sulfate, methyl, or acetyl moieties to functional groups introduced during Phase I metabolism. The resulting conjugates are more water-soluble, enabling efficient renal or biliary excretion.The major classes of Phase II enzymes include...
01:29Pharmacogenetic Phenotypes: Alterations in Pharmacokinetics, Drug Targets and Biologic Milieu
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...
01:11Pharmacogenetics of Drug Targets: β₂-Adrenergic Receptors, Apo E, Thymidylate Synthase
Genetic polymorphisms in drug targets have emerged as critical determinants of interindividual variability in drug response and toxicity. Pharmacogenomic investigations increasingly focus on identifying these variations to personalize and optimize therapeutic interventions. A drug target may be a receptor, enzyme, or signaling protein involved in pharmacologic responses or disease-related pathways. While early pharmacogenetic studies focused primarily on drug metabolism, current research...

01:27The Oral Microbiota
The oral microbiome includes a complex ecosystem comprising over 700 microbial species, identified through genomic sequencing and culture-based analyses to date. This community includes a core microbiome, found universally among individuals, and a variable component influenced by environmental factors such as diet, lifestyle, and host genetics. Site-specific conditions, including oxygen gradients, pH levels, and nutrient availability, determine the spatial distribution of these microorganisms...
01:29Alzheimer Disease l: Introduction
Alzheimer disease is a chronic, progressive, and irreversible neurodegenerative disorder and the most common cause of dementia in older adults. It leads to gradual neuronal loss, causing cognitive decline, behavioral changes, and loss of functional independence.Risk Factors and EtiologyThe disease is multifactorial. Age is the strongest risk factor, with prevalence doubling every 5 years after age 65. Genetic factors include mutations in genes such as APP, PSEN1, and PSEN2, which are associated...
