Insights

Genetic variants common in adults do not appear to predict early vascular changes in obese children. Instead, metabolic complications from obesity are the primary drivers of arterial alterations in this population.

Area of Science:

  • Pediatrics
  • Cardiovascular Genetics
  • Obesity Research

Background:

  • Adult studies indicate genetic factors contribute to vascular alterations and cardiovascular disease risk.
  • Research has not previously examined the role of gene polymorphisms in pediatric cardiovascular risk.
  • Childhood obesity presents a growing concern for long-term vascular health.

Purpose of the Study:

  • To investigate genetic variants associated with early vascular alterations in obese children.
  • To explore the co-involvement of gene polymorphisms as cardiovascular risk factors in pediatric populations.

Main Methods:

  • An association study was conducted in 232 obese children.
  • Functional gene variants in the renin-angiotensin system, vascular remodeling, inflammation, adiponectin, and lipoprotein metabolism were analyzed.
  • Non-invasive arterial measurements assessed common carotid artery mechanics and brachial artery endothelial function.

Main Results:

  • No significant association was found between the studied gene polymorphisms and arterial variables, individually or in combination.
  • The investigated genetic variants did not predict early vascular alterations in obese children.

Conclusions:

  • The hypothesis that specific genetic variants influence early vascular changes in obese children was not supported.
  • Obesity-related metabolic complications are identified as the primary predictors of arterial alterations in this cohort.
  • Further research may focus on metabolic pathways rather than specific gene polymorphisms for pediatric cardiovascular risk assessment.

Pharmacogenetic 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...

Pharmacokinetics in Obese Patients: Drug Absorption and Distribution

Obesity significantly alters the pharmacokinetic processes of drug absorption and distribution, presenting unique challenges in medical treatment. The increased fat tissue and decreased lean muscle in obese individuals can significantly affect how drugs are absorbed into the body and distributed across different tissues. This alteration can lead to variances in the effectiveness and safety of medications, necessitating adjustments in dosing or drug selection for obese patients.One notable...

Pharmacokinetics in Obese Patients: Drug Metabolism and Excretion

Drug metabolism, a critical process in the liver, involves two primary phases: Phase I reactions and Phase II conjugation. Obesity introduces significant alterations in this metabolic process, primarily due to fatty infiltration of the liver, leading to conditions such as nonalcoholic fatty liver disease (NAFLD). This condition can modify the activities of both Phase I and II enzymes, impacting how drugs are metabolized in obese patients.Phase I metabolism sees variable effects across...

Obesity

The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in adipocytes...

Pharmacogenomics: Identification of New Drug Targets

Advances in genomics have profoundly influenced drug discovery by increasing both the speed and accuracy of pharmaceutical development. Pharmacogenomics, which examines how genetic variation influences drug response, facilitates the identification of novel therapeutic targets and enables patient stratification for personalized treatment. These strategies contribute to improved drug efficacy, minimized adverse effects, and more efficient clinical trial design.Mapping genetic differences...

Drug Dosing: Obese Patients

In the United States, obesity is a prominent concern. It is linked to heightened mortality rates due to increased occurrences of conditions such as hypertension, atherosclerosis, coronary artery disease, and diabetes compared to nonobese individuals. A patient is classified as obese if their actual body weight surpasses the ideal or desirable body weight by 20%, based on Metropolitan Life Insurance Company data. Ideal body weights consider average weights and heights for males and females...
