Immunodeficiency
(Redirected from Immunocompromized)
Immunodeficiency refers to the inability of the immune system to properly defend the body against disease-causing organisms or pathogens, leading to an increased susceptibility to infections. This condition can be congenital or acquired and varies in severity from mild to life-threatening.
Overview[edit | edit source]
The immune system is a complex network of cells, tissues, and organs that work together to defend the body against attacks by foreign invaders, such as bacteria, viruses, fungi, and parasites. When this system is deficient or does not function properly, it results in an immunodeficiency disorder.
Types of Immunodeficiency[edit | edit source]
There are two main types of immunodeficiency disorders:
Primary Immunodeficiency[edit | edit source]
- Primary or Congenital Immunodeficiency disorders are typically present from birth and are caused by genetic defects. Examples include:
- Severe Combined Immunodeficiency (SCID) - A serious condition in which the patient has very few or no immune cells.
- Common Variable Immunodeficiency (CVID) - A disorder characterized by low levels of serum immunoglobulins.
- DiGeorge Syndrome - A condition caused by the deletion of a part of chromosome 22, leading to poor development of the immune system.
Secondary or Acquired Immunodeficiency[edit | edit source]
- Secondary or Acquired Immunodeficiency occurs later in life and can be due to various factors such as infections, malnutrition, aging, or as a side effect of treatments like chemotherapy.
- Acquired Immunodeficiency Syndrome (AIDS) - Caused by the Human Immunodeficiency Virus (HIV) that attacks and weakens the immune system.
Causes[edit | edit source]
Causes of immunodeficiency include, but are not limited to:
- Genetic mutations
- Environmental factors
- Chronic diseases
- Medications that suppress the immune system
Symptoms and Diagnosis[edit | edit source]
Symptoms of immunodeficiency can vary but may include:
- Recurrent infections
- Infections that are more severe than usual
- Delayed growth or development in children
- Autoimmune disorders
Diagnosis often involves:
- Blood tests to measure immune cell counts
- Immunoglobulin level testing
- Genetic testing to identify underlying genetic causes
Treatment[edit | edit source]
Treatment depends on the type and severity of the immunodeficiency and may include:
- Antibiotics or antifungal medications to treat and prevent infections
- Immunoglobulin Therapy to boost the immune system
- Bone Marrow Transplant or stem cell transplant for certain types of primary immunodeficiency
- Gene Therapy, which is a growing area of research for treating genetic causes of immunodeficiency
Living with Immunodeficiency[edit | edit source]
Patients with immunodeficiency disorders often need to take special precautions to avoid infections, such as practicing good hygiene, avoiding contact with sick individuals, and staying up-to-date with vaccinations.
