Relationship between erythrocyte 2,3-diphosphoglycerate and age in a normal population
Clinical Chemistry
|November 1, 1976
Summary
Erythrocyte 2,3-diphosphoglycerate levels decrease with age in the Greek population. Older adults over 60 exhibited significantly lower concentrations compared to younger individuals, indicating an age-related decline.
Area of Science:
- Biochemistry
- Human Physiology
- Gerontology
Background:
- 2,3-diphosphoglycerate (2,3-DPG) is a crucial molecule in erythrocytes regulating oxygen release.
- Age-related physiological changes can impact cellular metabolism and metabolite concentrations.
- Understanding 2,3-DPG levels in different age groups is important for assessing red blood cell function.
Purpose of the Study:
- To investigate the relationship between age and erythrocyte 2,3-diphosphoglycerate concentrations in a Greek population.
- To determine if there are significant differences in 2,3-DPG levels between younger and older adults.
Main Methods:
- Blood samples were collected from 369 males and 376 females of the Greek population, aged 1 to 86 years.
- Erythrocyte 2,3-diphosphoglycerate concentrations were measured using a validated biochemical assay.
- Statistical analysis was performed to assess correlations with age and differences between age groups.
Main Results:
- A significant inverse correlation was observed between age and erythrocyte 2,3-diphosphoglycerate levels (P < 0.01).
- Individuals over 60 years of age demonstrated significantly lower 2,3-DPG concentrations compared to those aged 1-20 years (P < 0.05).
Conclusions:
- Erythrocyte 2,3-diphosphoglycerate concentration declines with advancing age in the Greek population.
- This age-related decrease may have implications for oxygen transport efficiency in older adults.
- Further research is warranted to explore the functional consequences of these age-associated changes.

01:14Erythropoiesis
Red blood cells (RBCs) transport oxygen to all body tissues. These cells survive only for 120 days and then need to be replenished. Erythropoiesis is the process of RBC production. In healthy individuals, erythropoiesis ensures all tissues are amply supplied with oxygen. In addition, blood loss due to injury leads to a drop in the physiological oxygen level that will cause erythropoiesis. Any defect in erythropoiesis leads to several physiological disorders, including thalassemia, anemia, and...
01:24Factors Affecting Erythropoiesis
The cardiovascular system regulates the number of erythrocytes in the bloodstream to ensure optimal oxygen transport. It also prevents over-proliferation of these cells, which helps to maintain blood viscosity and flow rate.
Several factors influence the erythrocyte production rate, with tissue oxygen level being among the most critical. Intense exercise or high altitudes can cause tissue hypoxia, which triggers the kidneys to release more erythropoietin (EPO) into the bloodstream.

01:27Oxygen Transport in the Blood
Hemoglobin (Hb) is a crucial molecule in the human body, consisting of four polypeptide chains, each bound to an iron-containing heme group. This unique structure enables hemoglobin to bind to oxygen, with each molecule capable of combining with four molecules of oxygen, leading to rapid and reversible oxygen loading. When fully loaded with oxygen, it is called oxyhemoglobin, while hemoglobin that has released oxygen is called reduced hemoglobin or deoxyhemoglobin. As hemoglobin binds oxygen,...
01:22Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption
As individuals age, their body's physiology evolves, affecting drug pharmacokinetics. The most apparent changes occur in the gastrointestinal tract, where an increase in gastric pH, a delay in gastric emptying, and a reduction in gastrointestinal motility are observed. Remarkably, these changes do not substantially modify the absorption of orally administered drugs, particularly those absorbed via passive diffusion.Transdermal drug delivery emerges as a highly viable method for older adults due...
01:00Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Distribution
Drug distribution in the human body is influenced by several factors, including plasma protein concentration, body composition, blood flow, tissue-protein concentration, and tissue fluid pH. Among these, changes in plasma protein concentration and body composition due to aging significantly affect how drugs are distributed within the body. Specifically, aging is associated with a decrease in albumin levels by about 10% and an increase in α1-acid glycoprotein levels. These alterations are not...
01:27Pharmacodynamics in Geriatric Patients: Effects of Age
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...
