BACKGROUND: Donor-derived endemic mycoses are infrequently reported. We summarized the clinical characteristics and outcomes of these infections to provide guidance to transplant clinicians.
METHODS: Multiple databases were reviewed from inception through May 31, 2023 using endemic fungi as key words (e.g., Coccidioides, histoplasma, blastomyces, talaromyces, paracoccidioides). Only donor-derived infections (DDI) were included.
RESULTS: Twenty-four cases of DDI were identified from 18 published reports; these included 16 coccidioidomycosis, seven histoplasmosis, and one talaromycosis. No cases of blastomycosis and paracoccidiodomycosis were published. The majority were male (17/24,70.8%). Half of the cases were probable (12/24, 50%), seven were possible (29.2%), and only five were proven DDI (20.8%). Donor-derived coccidioidomycosis were observed in kidney (n = 11), lung (n = 6), liver (n = 3), heart (n = 2) and combined SOT recipients (1 KP, 1 KL) at a median time of .9 (range .2-35) months after transplantation. For histoplasmosis, the majority were kidney recipients (6 of 7 cases) at a median onset of 8 (range .4-48) months after transplantation. The single reported possible donor-derived talaromycosis occurred in a man whose organ donor had at-risk travel to Southeast Asia. Collectively, the majority of donors had high-risk exposure to Coccidioides (9/11) or Histoplasma sp. (6/6). Most donor-derived endemic mycoses were disseminated (18/24, 75%), and mortality was reported in almost half of recipients (11/24, 45.8%).
CONCLUSION: Donor-derived endemic mycoses are often disseminated and are associated with high mortality. A detailed evaluation of donors for the potential of an undiagnosed fungal infection prior to organ donation is essential to mitigate the risk of these devastating infections.
