Study Notes
Overview of Immunodeficiency Diseases in Children
- Immunodeficiency diseases result from a defect in the immune system, leading to increased susceptibility to infections.
- They can be primary (genetic) or secondary (acquired).
Types of Immunodeficiency Diseases
-
Primary Immunodeficiency (PID)
- Genetic disorders that affect immune function.
- Examples:
- Severe Combined Immunodeficiency (SCID): Lack of T and B lymphocytes; requires immediate treatment.
- X-Linked Agammaglobulinemia: Deficiency of antibodies; males predominantly affected.
- Common Variable Immunodeficiency (CVID): Low levels of antibodies causing recurrent infections.
- Hyper-IgM Syndrome: Increased IgM levels but low IgG, IgA.
-
Secondary Immunodeficiency
- Result from external factors.
- Examples:
- Malnutrition: Insufficient nutrients impair immune response.
- HIV/AIDS: Virus attacks immune cells, particularly CD4+ T-cells.
- Cancer and Chemotherapy: Can suppress immune function.
- Chronic diseases: Conditions like diabetes or liver disease may affect immunity.
Symptoms
- Frequent infections (ear, sinus, lung).
- Unusual infections (e.g., fungal or viral).
- Poor growth and weight gain.
- Autoimmune issues (in some cases).
Diagnosis
- Clinical Evaluation: History of infections, growth patterns, family history.
-
Laboratory Tests:
- Complete blood counts (CBC).
- Immunoglobulin levels.
- Specific antibody responses (to vaccines).
- Genetic testing (for PIDs).
Treatment
- Infection Management: Immediate treatment of infections with antibiotics or antivirals.
- Immunoglobulin Therapy: For those with antibody deficiencies.
- Bone Marrow Transplant: Curative option for some PIDs (e.g., SCID).
- Gene Therapy: Emerging treatment for certain genetic defects.
- Prophylactic Antibiotics: To prevent infections in high-risk patients.
Monitoring and Care
- Regular follow-ups with immunologists.
- Vaccination with inactivated vaccines; caution with live vaccines.
- Supportive care for nutritional needs and growth.
Prognosis
- Varies significantly among different types and severity of immunodeficiency.
- Early diagnosis and intervention improve outcomes.
Immunodeficiency Diseases in Children
- Immunodeficiency is a condition where the immune system is compromised, leading to increased susceptibility to infections.
-
Primary immunodeficiency (PID) is caused by genetic defects, affecting immune function.
- Severe Combined Immunodeficiency (SCID): Lack of T and B lymphocytes, requiring immediate treatment.
- X-Linked Agammaglobulinemia: Deficiency of antibodies, primarily affecting males.
- Common Variable Immunodeficiency (CVID): Low antibody levels leading to recurrent infections.
- Hyper-IgM Syndrome: High IgM levels but low IgG and IgA.
-
Secondary immunodeficiency results from external factors, such as:
- Malnutrition: Insufficient nutrients impacting immune response.
- HIV/AIDS: Virus attacks immune cells, particularly CD4+ T-cells.
- Cancer and Chemotherapy: Suppression of immune function.
- Chronic diseases: Conditions like diabetes or liver disease can affect immunity.
