Another major axis of dealing with invasive aspergillosis infection in neutropenic patients is the recovery of neutropenia itself.[11] Adjunctive measures, namely granulocyte transfusions and granulocyte colony-stimulating factor, can be considered.[7] However, the control of underlying disease to induce bone marrow function recovery is ultimately fundamental in overcoming neutropenia. The gene discussed is CSF3; the disease is neutropenia.
