Disorders of Erythrocytes01:27

Disorders of Erythrocytes

945
Disorders of erythrocytes, or red blood cells (RBCs), include a range of conditions affecting their number, shape, or function.
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.
On the other...

Erythropoiesis01:14

Erythropoiesis

4.3K
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,...

Factors Affecting Erythropoiesis01:24

Factors Affecting Erythropoiesis

3.3K
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.
EPO then...

Anorexia Nervosa01:28

Anorexia Nervosa

73
Anorexia nervosa is a complex and severe eating disorder characterized by an intense fear of weight gain, an unrelenting pursuit of thinness, and a distorted body image. It often leads to dangerously low body weight relative to an individual's age and height. This disorder is marked by significant physical and psychological consequences, making it one of the most life-threatening psychiatric illnesses.
Symptoms and Physical Effects

Hypoxia01:23

Hypoxia

1.1K
Hypoxia is a medical condition characterized by an inadequate oxygen supply to body tissues. It typically manifests as a bluish discoloration of the skin and mucosae, especially in fair-skinned individuals, when hemoglobin (Hb) saturation drops below 75%.
Types of Hypoxia
There are four primary types of hypoxia, each resulting from a different cause:
1. Anemic hypoxia: This type occurs due to insufficient oxygen delivery caused by a lack of red blood cells (RBCs) or RBCs with abnormal or...

Area of Science:

  • Hematology
  • Internal Medicine

Context:

  • Anaemia diagnosis presents challenges, particularly differentiating iron deficiency anaemia from anemia of chronic disease (ACD), also termed inflammatory anaemia.
  • Despite extensive research, distinguishing these common anaemia types requires careful clinical evaluation.

Purpose:

  • To provide clinicians with practical factors for differentiating iron deficiency anaemia and ACD.
  • To offer guidance on iron metabolism, supplementation, haemoglobin cut-off values in the elderly, and reticulocyte response interpretation.

Summary:

  • This article details methods for distinguishing iron deficiency anaemia from ACD, including iron transport parameters and bone marrow examination.
  • It covers iron metabolism, supplementation strategies, and interpreting reticulocyte response and haemoglobin levels in older adults.
  • The utility of manual blood smear analysis for anaemia classification is also discussed.

Impact:

  • Aids clinicians in accurate anaemia diagnosis, leading to more effective patient management.
  • Improves understanding of iron metabolism and anaemia pathophysiology.
  • Enhances diagnostic accuracy for common anaemia types in clinical practice.
