Overview & Definition
Immunodeficiency disorders occur when the immune system lacks necessary white blood cells or immunoglobulins, leaving the body vulnerable to severe, frequent, and unusual infections.
Types & Classification
- Common Variable Immunodeficiency (CVID)
- X-Linked Agammaglobulinemia (XLA)
- Selective IgA Deficiency
- Severe Combined Immunodeficiency (SCID)
- Secondary Immunodeficiency (Post-chemo / Myeloma)
Underlying Causes & Risk Factors
- Genetic mutations affecting B-cell or T-cell development
- Hematological malignancies & bone marrow failure
- Immunosuppressive chemotherapy or radiation
Common Symptoms & Warning Signs
Diagnostic Evaluation
Accurate diagnosis requires comprehensive laboratory investigation under expert hematological supervision:
- 🔍 Serum Immunoglobulin Levels (IgG, IgA, IgM, IgE)
- 🔍 Flow Cytometry Lymphocyte Subsets (CD4, CD8, CD19, CD56)
- 🔍 Vaccine Response Antibody Testing
- 🔍 Genetic Sequencing Panels
Treatment Options & Clinical Management
Under the guidance of Dr. Saikat Datta and Dr. Sachin Bansal, treatment strategies are tailored to individual clinical severity:
- 💊 Intravenous Immunoglobulin (IVIG) & Subcutaneous Immunoglobulin (SCIG)
- 💊 Prophylactic Antibiotic & Antifungal Regimens
- 💊 G-CSF Growth Factor Therapy
- 💊 Allogeneic Hematopoietic Stem Cell Transplant (Curative for SCID)
Frequently Asked Questions
Early indicators include persistent fatigue, unexpected blood count changes on routine CBC, easy bruising, or frequent infections. Early consultation with a specialist ensures timely intervention.
Diagnosis involves detailed peripheral blood smear examination, specialized blood biomarker panels, and where indicated, bone marrow aspiration or genetic screening.
