EMPIRIC THERAPY

George R Thompson, III, MD: What is the role of empiric therapy in pediatrics when you have symptoms suggestive of an invasive infection?

Antonio Arrieta, MD: We are quite aggressive, I would say. The problem comes when you have to decide if you’re dealing with Aspergillus spp. or you’re dealing with a different fungus. The empiric treatment of invasive fungal disease is complicated, and often we have to decide to use liposomal amphotericin B at higher doses than typically recommended for the treatment of Mucor that will also treat Aspergillus spp. Often, we have to consider using azole agents that have activity against some of the Mucorales, such as isavuconazole or posaconazole.26 But, we try to start empirically early while we continue to try to identify the fungus.

George R Thompson, III, MD: That speaks to sometimes the uncertainty of diagnosis. In those circumstances, we’ve often really wanted to use a non-voriconazole mold agent just to cover Mucorales as well.
