Caspofungin therapy for Aspergillus lung infection in a boy with chronic granulomatous disease

Neutrophils of patients with chronic granulomatous disease (CGD) are profoundly defective in killing microorganisms. As in patients with chemotherapy-induced neutropenia, CGD patients are highly susceptible to life-threatening invasive Aspergillus infections, and conventional antimycotic treatment is not always successful. The new drug, caspofungin, was used to treat Aspergillus lung infection in one child with CGD.
