Improved outcome of zygomycosis in patients with hematological diseases?

Abstract

Zygomycosis is an opportunistic fungal infection that is increasingly reported in hematological patients. We describe 2 cases of successfully treated rhino-cerebral zygomycosis and give an overview of 120 patients from the literature with underlying hematological or oncological disorders. These data document the improved survival in sinus (15/17 patients surviving) and cutaneous (6/9 patients surviving) disease. Hematological patients with pulmonary (9/30 patients surviving) or disseminated (4/38 patients surviving) zygomycosis still have a poor prognosis. The clinical course of sinus-orbital involvement (4/11 patients surviving) follows sinus-cerebral (2/3 patients surviving) or cerebral (3/6 patients surviving) disease. Besides deoxycholate amphotericin B (AmB) (24/62 patients surviving), patients seem to benefit from liposomal amphotericin B (L-AmB) (10/16 patients surviving) or sequential AmB/L-AmB treatment (6/8 patients surviving). Alternative treatment options lead only in a few patients to success.
