    2. Avoid Medication Causes of Neutropenia
  1. General
    1. Most common in advanced HIV and AIDS
  2. Causes: Early HIV
    1. Immune Thrombocytopenic Purpura (ITP)
      1. Antibodies to HIV envelope Glycoprotein (GP120) cross react with Glycoprotein IIB/IIIA
  3. Causes: Late HIV
    1. Megakaryocyte infection with HIV
  4. Causes: Other Factors
    1. Drug induced Thrombocytopenia (e.g. Trimethoprim-Sulfamethoxazole, Rifampin)
    2. Comorbid Hepatitis CVirus Infection

  1. Vitamin Deficiency
    1. Vitamin B12 Deficiency
    2. Folate Deficiency
    3. Iron Deficiency
      1. Chronic inflammation in HIV also effects iron levels (decreased TIBC, Serum Iron; elevated Ferritin)

  5. Bone Marrow Suppression or Infiltration
    1. Parvovirus B19
    2. Histoplasmosis
    3. Lymphoma

  6. Management
    1. Anti-Retroviral Therapy
    2. Treat specific causes
      1. Vitamin Deficiency (e.g. Iron Deficiency)
      2. Erythropoiesis Simulating Agent (Erythropoietin, Epoetin) if indicated
      3. Corticosteroids (for Autoimmune Hemolytic Anemia)
      4. Bone Marrow Biopsy if indicated
