Adrenal Gland Disorders01:27

Adrenal Gland Disorders

2.9K
Adrenal gland disorders manifest when the production of adrenal hormones deviates from the norm, resulting in either excessive or insufficient concentrations.
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss. Congenital adrenal hyperplasia, a genetic ailment causing...

Drug Dosing: Geriatric Patients

222
Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...

Pharmacodynamics in Geriatric Patients: Effects of Age

185
Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Metabolism

195
Geriatric patients show significant variation in how their bodies process medications, which can change how effective and safe treatments are. The liver is the primary organ where drug metabolism occurs, involving two main types of chemical reactions: phase I and II. Phase I metabolism is driven by the cytochrome P450 enzyme system, which includes key types such as CYP3A, CYP2D6, and CYP2C9. Research indicates that while aging doesn't notably alter the levels or activity of these enzymes, it...

Anatomy of the Adrenal Glands01:17

Anatomy of the Adrenal Glands

4.3K
The adrenal or supra-renal glands, situated above the kidneys and aligned with the twelfth rib, are paired pyramid-shaped structures crucial for the body's stress response. During stress, these glands secrete hormones vital for adaptive physiological reactions.
These glands possess a distinctive yellow tinge due to the stored cholesterol and fatty acids required for hormone synthesis. They are encased in a fibrous capsule and cushioned by fat.
The adrenal gland comprises two distinct...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Excretion01:18

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Excretion

233
In geriatric patients, renal physiology undergoes significant changes, including diminished renal blood flow and a lower glomerular filtration rate (GFR), leading to alterations in medication clearance. Drugs such as aminoglycoside antibiotics, lithium, and digoxin, which rely on glomerular filtration for removal from the body, particularly impact pharmacokinetics. These drugs tend to have slower clearance rates in older adults, necessitating careful dosage considerations.Evaluation of renal...

Summary

Aging impacts adrenal tumor development and progression. Older patients with adrenal tumors, especially adrenocortical carcinoma (ACC), face poorer outcomes due to age-related biological changes. Further research is needed to understand these links.

Area of Science:

  • Endocrinology
  • Oncology
  • Gerontology

Background:

  • Adrenal tumor incidence increases with age.
  • The relationship between adrenal aging and tumorigenesis is not well understood.
  • Aging affects adrenal structure, function, and immune balance.

Purpose of the Study:

  • To review age-related changes in the adrenal gland.
  • To examine how aging influences adrenal tumors, including adrenocortical carcinoma (ACC).
  • To identify knowledge gaps and guide future research on aging and adrenal neoplasms.

Main Methods:

  • Mini-review of existing literature.
  • Summary of age-related structural and functional changes in adrenal cortex and medulla.
  • Examination of clinical data and preclinical models for adrenal tumors in the elderly.

Main Results:

  • Aging alters adrenal structure, steroidogenesis, and homeostasis.
  • Older patients with ACC have worse clinical outcomes.
  • Senescence, inflammation, and immune factors may influence ACC behavior.
  • Data on pheochromocytomas and rare adrenal neoplasms in the elderly are limited.

Conclusions:

  • Aging influences the biology and clinical course of adrenal tumors.
  • Translational inferences from preclinical models require further clinical validation.
  • Systematic studies are needed to elucidate the role of aging in adrenal tumorigenesis and improve care for older patients.
