Interferon-gamma Immunotherapy in a Patient With Refractory Disseminated Candidiasis.
Despite advances in supportive care and novel antifungal agents, mortality caused by invasive Candida infection is high. A 3-year-old boy with disseminated Candida dubliniensis infection during induction chemotherapy for acute lymphoblastic leukemia deteriorated despite resolution of neutropenia and appropriate antifungal treatment. Monocyte human leukocyte antigen-DR expression was extremely low, suggesting immunoparalysis. Adjuvant immunotherapy with interferon-gamma restored the immune response, which was accompanied by clinical and radiographic recovery.
