What Are Immune Dysregulation Disorders
A healthy immune system maintains a careful balance. It must respond strongly enough to protect the body against infections, while recognising the difference between harmful substances and the body’s own healthy tissues.
Immune dysregulation disorders occur when this balance is disrupted, causing the immune system to become either underactive or overactive. An underactive immune system makes it harder for the body to fight infections, while an overactive immune system may attack healthy tissues, overreact to harmless substances or cause excessive inflammation.
Immune dysregulation disorders encompass a broad range of conditions, including immunodeficiencies, autoimmune diseases, allergic diseases and autoinflammatory disorders. Although these conditions affect the immune system in different ways, they all arise from abnormalities in how the immune system is regulated.
Accurately identifying the underlying immune disorder is important, as management depends on the specific cause rather than the symptoms alone.
What Symptoms May Suggest an Immune Dysregulation Disorder?
Symptoms vary depending on whether the immune system is underactive or overactive. Some people experience recurrent infections because their immune system cannot respond effectively, while others develop excessive immune responses that cause inflammation, allergies or autoimmune disease.
Symptoms of an Underactive Immune System
- Frequent or persistent infections
- Infections that are difficult to treat
- Poor wound healing
- Chronic diarrhoea
Symptoms of an Overactive Immune System
- Persistent joint pain or swelling
- Skin rashes
- Allergic rhinitis, asthma or eczema
- Food allergies or anaphylaxis
- Chronic hives
- Unexplained fevers or ongoing inflammation
- Fatigue associated with autoimmune disease
These symptoms do not always indicate an immune dysregulation disorder, but if they are persistent, recurrent or affecting your quality of life, it is advisable to seek medical evaluation to identify any underlying immune problem.
What Causes Immune Dysregulation Disorders?
Immune dysregulation disorders can develop for different reasons. Some are primary, meaning they are caused by inherited genetic changes that affect how the immune system develops or functions. Although these conditions are present from birth, their symptoms may not always become apparent until later in life.
Others are secondary, meaning the immune system becomes dysregulated as a result of another condition or external factor, such as:
Certain infections
Medications that affect the immune system
Chronic medical conditions
Cancer and its treatment
Age-related changes in immune function
How Are Immune Dysregulation Disorders Diagnosed?
Diagnosing an immune dysregulation disorder involves identifying not only whether the immune system is functioning abnormally, but also how it is being affected. As many immune disorders share similar symptoms, a detailed assessment is often needed.
This process may involve:
Discussion of your symptoms
Your clinical immunologist will ask about your symptoms, when they began, how they have changed over time, your history of recurrent infections, allergies or autoimmune conditions, and whether there is a family history of immune disorders.
Physical examination
A physical examination may be performed to look for signs of infection, inflammation, allergic disease or autoimmune conditions that may provide clues to the underlying immune disorder.
Blood tests
Blood tests may be recommended to assess different aspects of your immune system, including immune cell counts, immunoglobulin levels, markers of inflammation and other indicators of immune function.
Additional investigations
Depending on your symptoms and clinical history, further investigations such as allergy testing, immune function tests, genetic testing, flow cytometry or imaging may be recommended where appropriate.
By bringing together these findings, your clinical immunologist can build a clearer understanding of how your immune system is functioning and determine the underlying immune disorder.
Managing Immune Dysregulation Disorders
Management begins with understanding how the immune system is being affected, as no two immune dysregulation disorders are exactly alike. At Aaria Rheumatology, treatment is guided by your diagnosis, symptoms and overall health, with the aim of helping restore immune balance where possible and reducing the impact of the condition on your daily life. Depending on your underlying immune disorder, management may include:
Medications
Treatment may involve medications to regulate immune activity, control inflammation or manage specific immune-related conditions.
Preventing infections
For patients with immunodeficiency disorders, management may include strategies to reduce the risk of recurrent infections and treat infections promptly when they occur.
Allergy management
Where allergies are part of the underlying immune disorder, management may include allergen avoidance, emergency preparedness or allergy immunotherapy where appropriate.
Ongoing monitoring
Regular follow-up allows your doctor to monitor your condition, review your response to treatment and adjust your management plan as your needs change over time.
This approach helps ensure that treatment continues to address your changing symptoms and supports your long-term immune health.
