Study Notes
Primary Immunodeficiency States (IDS)
- Primary immunodeficiency states (IDS) of adaptive immunity predominantly affect the T-cell or B-cell links.
Types of Immunodeficiency
- Combined immunodeficiency involves a decrease in the functional activity of the main components of the immune system.
Secondary Immunodeficiencies
- The main cause of the formation of secondary immunodeficiencies is a decrease in the functional activity of the immune system due to various external factors.
- The main causes of secondary immunodeficiencies include infections, cancers, immune disorders, and treatments that suppress the immune system.
Phagocytic Link Deficiencies
- Primary deficiencies of the phagocytic link of innate immunity are primarily associated with defects in the structure and function of phagocytic cells, such as neutrophils and macrophages.
Age-Related Immunodeficiencies
- Physiological (age-related) immunodeficiencies are primarily attributed to the decline of immune function with aging.
- The role of physiological (age-related) immunodeficiencies is to impair the body's ability to respond to infections and diseases.
T-Cell Link Deficiencies
- Immunodeficiency involving a predominant lesion of the T-cell link in adaptive immunity is known as T-cell immunodeficiency.
Characteristics of Immunodeficiency States
- The main characteristic of immunodeficiency states (IDS) is the impaired ability of the immune system to respond to infections and diseases.
B-Cell Link Deficiencies
- In primary immunodeficiency states, the predominant lesion of the B-cell link is associated with defects in antibody production and humoral immunity.
