Causes

Hypogammaglobulinemia is caused by:

Immunodeficiency secondary to:

  • Protein-losing gastroenteropathy
  • Nephrotic syndrome
  • Thymoma [1]
  • Medications :
    • Gold
    • D-Penicillamine
    • Sulfasalazin
    • Anticonvulsants
    • Glucocorticoids
    • Methotrexate
    • Calcineurin inhibitors
    • Rituximab[2][3][4]
  • Environmental hazards:
    • Ionizing radiation
    • Toxins
  • Infections
    • Viral(Herpes, Measles)
    • Bacterial(Mycobacterial)
    • Parasitic(Malaria, helminthic infections)
