Study Notes
Immunodeficiency
- Immunodeficiency can be primary (congenital/inherited) or secondary (acquired).
- Primary immunodeficiency is caused by genetic mutations.
- Secondary immunodeficiency is caused by external factors.
Primary Immunodeficiency
- Genetic defects affect immune system components.
- Examples: SCID (Severe Combined Immunodeficiency), XLA (X-linked Agammaglobulinemia), DiGeorge Syndrome, CGD (Chronic Granulomatous Disease).
- SCID: Defect in both T and B cells, leading to severe susceptibility to infections.
- XLA: Lack of mature B cells due to a defect in the BTK gene.
- DiGeorge Syndrome: Chromosomal deletion affecting the thymus, leading to T cell deficiencies.
- CGD: Defective phagocytes that cannot produce reactive oxygen species to kill pathogens.
- Affected individuals are susceptible to opportunistic infections (fungal, viral, bacterial)
Secondary Immunodeficiency
- Caused by external factors weakening the immune system.
- Examples: HIV/AIDS, malnutrition, chronic diseases (diabetes, kidney disease, cancer), medical interventions (chemotherapy, radiation, immunosuppressants), and infections (tuberculosis, measles).
- HIV: Targets CD4 T cells, leading to AIDS.
- Malnutrition: Deficiency in essential nutrients impairs immune function.
- Chronic Diseases: Diabetes, kidney disease, cancer damage immune function
- Medical Interventions: Chemotherapy and radiation reduce white blood cell production.
- Infections: Certain infections suppress immune function
Immunodeficiency and Oral Tissues
- Immunodeficiency increases risk of oral infections, including fungal (oral candidiasis), bacterial (periodontal disease, dental abscesses), and viral.
- Delayed healing is common with immunodeficiency.
- Oral manifestations of systemic conditions that manifest with immunodeficiency: oral candidiasis, hairy leukoplakia, necrotizing ulcerative gingivitis, periodontal disease, Epstein-Barr virus (EBV), Kaposi's sarcoma
- Immunodeficiency patients are more susceptible to oral diseases.
Diagnostic and Investigative Tools
- Complete Blood Count (CBC): Assesses leukocyte levels.
- Immunoglobulin Testing: Measures IgG, IgA, and IgM to detect antibody deficiencies.
- Flow Cytometry: Identifies immune cell populations (T cells, B cells, NK cells).
- Functional Assays: Evaluates specific immune functions (phagocytosis, complement activation).
- Genetic Testing: Identifies genetic causes through mutation analysis.
- Infection Screening: Detects common pathogens like HIV, TB, etc
Implications for Dental Care
- Frequent Monitoring: Regular dental checkups for infections.
- Infection Control: Prophylactic antifungal/antibacterial treatment for high-risk patients.
- Supportive Care: Addressing symptoms (xerostomia), providing pain relief, and ensuring proper nutrition.
- Collaboration: Close coordination with medical teams to manage underlying conditions.
Important Human Pathogens associated with immunodeficiency
- Fungal: Candida albicans, Aspergillus spp.
- Bacterial: Mycobacterium tuberculosis, Streptococcus pneumonia
- Viral: HSV-1, HSV-2, CMV, EBV
- Parasitic: Toxoplasma gondii
Latrogenic immunodeficiency
- Caused by treatments and interventions potentially damaging the immune system.
- Includes chemotherapy/radiation therapy, immunosuppressive drugs (corticosteroids, biologics), and splenectomy.
