Secondary Lymphoid Organs01:15

Secondary Lymphoid Organs

1.9K
Secondary organs, including lymph nodes, the spleen, and mucosa-associated lymphoid tissue (MALT), work harmoniously to protect us from disease and infection.
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...

Rheumatic Heart Disease I: Introduction

31
Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...

Regulation of Hematopoietic Stem Cells

3.3K
All blood and immune cells are produced from the multipotent hematopoietic stem cells (HSCs) by the process of hematopoiesis. However, they all have a limited life span. In addition, many are depleted in immune surveillance or combatting an injury or infection. This makes blood one of the most regenerative tissues. Hematopoiesis helps replenish these blood and immune cells, restoring the body's normal functioning. However, overproduction of blood and immune cells can make them cancerous or...

Bone Marrow Sampling and Transplants

397
Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.
The transplant begins with high doses of chemotherapy and radiation treatment, which aim to destroy...

Disorders of Erythrocytes01:27

Disorders of Erythrocytes

1.1K
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...

Summary

Asplenia (spleen absence) and hyposplenism (impaired spleen function) heighten infection risk. Early recognition, vaccination, and antibiotic prophylaxis are crucial for preventing severe infections in at-risk individuals.

Area of Science:

  • Immunology
  • Hematology
  • Infectious Diseases

Background:

  • Asplenia and hyposplenism compromise immune function and blood filtration.
  • These conditions increase susceptibility to severe infections, particularly from encapsulated bacteria like Streptococcus pneumoniae.

Purpose of the Study:

  • To highlight the clinical significance of asplenia and hyposplenism.
  • To emphasize the need for improved management strategies, including vaccination and prophylaxis.

Main Methods:

  • Review of existing literature on spleen function and related disorders.
  • Analysis of clinical manifestations and causative factors of asplenia/hyposplenism.

Main Results:

  • Asplenia often results from splenectomy; hyposplenism arises from various conditions.
  • Impaired spleen anatomy and reduced IgM memory B cells contribute to clinical issues.

Conclusions:

  • Early detection of hyposplenism and management of asplenia are vital.
  • Enhanced vaccination strategies, screening programs, and patient education are necessary.
