In a retrospective analysis, 18 instances of invasive fungal infection
s were observed in 512 (3.5%) renal transplant recipients. These inclu
ded candidiasis (8), aspergillosis (5), cryptococcosis (3) and zygomyc
osis (2). All patients with candidiasis had Candida isolated from bloo
d and one or more additional sites. One of them had superadded fungaem
ia with Torulopsis glabrata. Pulmonary disease in four and subcutaneou
s infection in one were encountered in the five patients with aspergil
losis. Central nervous system involvement in two and cutaneous lesion
in one were the findings in patients with cryptococcosis. Zygomycosis
involved the lung in one and the allograft itself in the other. Prolon
ged fever not responding to antibacterial drugs was the most common cl
inical presentation. Fungal infections occurred during the first 4 mon
ths in 10 (55.5%) and 12 to 108 months in eight (44.5%) patients. Infe
ctions with cytomegalovirus and hepatitis viruses were concommitantly
present in 12 (66.7%) and eight (44.5%) patients respectively. Fourtee
n episodes of fungal infections (77.8%) occurred in live unrelated kid
ney recipients who formed only 48% of our total transplant population.
Nine patients were treated with systemic and/or local amphotericin B
and six with amBisome. Fluconazole was administered alone in three and
in combination with amphotericin B in two. Fourteen patients died but
mortality was only directly attributable to fungal infection in 11. W
e conclude that invasive fungal infections continue to be an important
cause of morbidity and mortality in renal transplant recipients. A hi
gh index of suspicion, prompt diagnosis mid early institution of speci
fic antifungal therapy are needed.
