Immunodeficiency
Immunodeficiency refers to a state in which the immune system's ability to fight infections and other diseases is compromised or entirely absent. This condition can be inherited (primary immunodeficiency) or acquired due to infections, medications, or other environmental factors (secondary immunodeficiency).

Types of Immunodeficiency
Understanding the different types of immunodeficiency is essential for determining appropriate treatment and management. Here are the main types:
​
-
Primary Immunodeficiency Disorders (PIDs): These are inherited genetic disorders, with common examples including Severe Combined Immunodeficiency (SCID) and Common Variable Immunodeficiency (CVID). They often manifest early in life and may require lifelong management.
-
Acquired Immunodeficiency: This type develops after birth, commonly due to infections like HIV or factors such as chemotherapy, malnutrition, or certain medications. Acquired immunodeficiency can vary in severity depending on the cause and duration of exposure.
-
Selective Immunoglobulin Deficiencies: Certain immunoglobulins (antibodies) may be absent or deficient, weakening the immune response to specific infections. This is often due to genetic mutations.
What are the symptoms of immunodeficiency
Symptoms can vary widely depending on the severity and type of immunodeficiency but often include:
​
-
Frequent infections: Including respiratory, sinus, ear, and skin infections that are persistent or unusually severe.
-
Slow recovery: Infections may take longer than usual to heal, even with standard treatments.
-
Digestive issues: Diarrhea, malabsorption, and chronic gastrointestinal discomfort.
-
Autoimmune symptoms: Some individuals may experience autoimmune reactions where the body mistakenly attacks its own tissues.
-
Failure to thrive in children: Poor growth or development delays can be signs of primary immunodeficiency.
It's essential to note that severe symptoms like recurrent high fevers, persistent infections, and unusual or hard-to-treat infections should prompt medical evaluation.
Diagnosis
Diagnosing immunodeficiency involves a comprehensive evaluation by a healthcare professional.
​
Several diagnostic steps include:
​
-
Medical history: A detailed record of past infections, symptoms, family history, and any immunocompromising factors.
-
Physical examination: A thorough physical check to identify any visible signs of immune compromise.
-
Blood tests: To assess levels of immune cells, immunoglobulins, and antibodies.
-
Genetic testing: For suspected inherited immunodeficiencies, genetic testing may help confirm the diagnosis.
-
Specialized immune function tests: Tests such as flow cytometry to evaluate the function of specific immune cells.
Timely diagnosis is vital for managing symptoms and preventing severe complications.
Treatment Options
Treatment depends on the type and severity of immunodeficiency and may include:
​
-
Immunoglobulin replacement therapy: Regular infusions of immunoglobulins to provide necessary antibodies.
-
Antibiotics and antifungal medications: Used preventatively or to treat infections.
-
Vaccinations: Modified vaccination schedules to prevent infections.
-
Bone marrow or stem cell transplants: For severe cases of primary immunodeficiency.
It’s crucial to work closely with a healthcare provider to develop a personalized treatment plan.
Prevention
Preventing immunodeficiency is challenging, especially with inherited forms. However, the following steps may reduce infection risks for those affected:
​
-
Good hygiene: Regular handwashing and avoiding contact with sick individuals.
-
Healthy diet: A nutrient-rich diet supports immune function.
-
Vaccinations: Maintaining recommended vaccinations as advised by healthcare providers.
-
Avoiding known triggers: In cases of secondary immunodeficiency, avoid exposure to immunosuppressive substances or medications where possible.
Proactive care and regular medical monitoring are essential to managing immunodeficiency effectively.
