Medical and Adjunctive Treatment of Mucormycosis in Children: Scientific Rationale and Analysis of Cases Reported in the Literature

Mucormycosis is associated with significant morbidity and mortality in both children and adults. Studies have shown an increase in the incidence of mucormycosis, particularly among hematopoietic stem cell transplant (HSCT) recipients, patients with hematologic malignancies, and those with diabetic ketoacidosis. The infection typically presents as soft tissue, rhinoorbitocerebral, pulmonary, or disseminated disease and is characterized by rapid clinical progression and high mortality rates. Treatment with amphotericin B lipid formulations in combination with surgery offers the best option for treatment and survival; posaconazole, a relatively new antifungal triazole, is increasingly used for consolidation or salvage therapy. Because of the poor prognosis of zygomycosis, particularly in immunocompromised cancer patients, adjunctive treatments such as hyperbaric oxygen therapy, use of immunomodulatory cytokines, and in vivo iron chelation continue to be explored. Thus far, it is unclear how these adjunctive treatments can be harnessed to impact outcomes and which patients may benefit from them.
