Abstract:
Pegfilgrastim is a granulocyte colony-stimulating factor agent used in patients receiving myelosuppressive therapy with chemotherapy or radiation. Two adverse effects associated with this agent include capillary leak syndrome and leukocytosis. To our knowledge, this is the first case of a patient who developed both systemic capillary leak syndrome and leukocytosis greater than 100,000 cells/µL after receiving pegfilgrastim. This patient received early fluid resuscitation, vasopressor support, and methylprednisolone, which improved her clinical course during hospitalization.

Disorders of Leukocytes
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune...
