The role of adjuvant agents in treating fungal diseases

Invasive fungal infections (IFIs) remain a significant cause of morbidity and mortality despite the recent introduction of new antifungal medications. In this review, the available data on the use of adjuvant agents for the treatment of IFIs are discussed. Cytokines such as interferon-γ, colony-stimulating factors, granulocyte transfusions, and the monoclonal antibody efungumab may have in a role in the management of IFIs through augmentation of the host immune response, whereas pathogen-specific vaccines may help prevent infection. Pentraxin 3, an acute phase protein, may assist in the prevention and treatment of aspergillosis. Deferasirox, an iron chelator, is being investigated as an adjunctive therapy for the treatment of zygomycosis. Lactoferrin, an ironbinding protein, appears to have activity in Candida and Aspergillus infections, and omiganan may help prevent fungal catheter-related infections. Although none of these agents are currently approved for the treatment of IFIs, they may be involved in current and/or future treatment options when used in combination with antifungal drugs.
