 '''Immunodeficiency''' refers to the inability of the [[Immune System|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.
 == Introduction ==
 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.

== Overview ==
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 ==
There are two main types of immunodeficiency disorders:

=== Primary Immunodeficiency ===
* '''[[Primary Immunodeficiency|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 ===
* '''[[Secondary immunodeficiency|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 ==
Causes of immunodeficiency include, but are not limited to:
* Genetic mutations
* Environmental factors
* Chronic diseases
* Medications that suppress the immune system

== Symptoms and Diagnosis ==
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 ==
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 ==
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.

* [[Human Immunodeficiency Virus (HIV)]]
