To Bite the Bullet of Early Graft Nephrectomy: A Case Report
A. Pradhan, S. Gadela, R.S.V. Kumar, A. Kalghatghi, and S. Pradhan
ABSTRACT
Isolated renal allograft mucormycosis is rare. Only 8 cases have been reported to date, with
patient survival in only 3. We recently encountered a case. The presentation was fever and
graft dysfunction, which were unresponsive to extended antibiotic treatment and support-
ive care. It was only after three graft biopsies that mucormycosis was diagnosed and
amphotericin B started. Urgent graft nephrectomy was performed, but the patient died of
septicemia. In retrospect, we believe that early institution of amphotericin B and graft
nephrectomy are needed for patient salvage in this difficult clinical situation.
F
UNGAL infections are rare, occuring in about 10% of
renal allograft recipients,
1
but they are associated with a
high mortality. Mucormycosis (phycomycosis, zygomycosis)
can be ubiquitous, present in the air, water, and soil. They
belong to the order Mucorales of the class Zygomycetes. The
various species include Rhizopus arrhizus, Rhizopus oryzae,
Absidia corymbifera, Abisidia ramosa, Mucor pusillus, and other
species of Mucor, Basidiobolus, Mortierella, and Cunningha-
mella.

Infections occur in immunocompromised states like
organ transplantation, diabetes mellitus, malignancies, and
burns. On fungal stains, hyphae typically appear to be broad
based and septate. They have a propensity to invade blood
vessels, causing thrombosis, infarction, and necrosis with ab-
scess formation. Rhinocerebral, pulmonary, cutaneous, and
gastrointestinal lesions are the commonest forms.

The only
effective treatment for the condition is vigorous surgical extir-
pation of the focus together with systemic amphotericin B. We
report a case of isolated renal allograft mucormycosis.
CASE REPORT
A 22-year-old male patient reached end-stage renal disease due to
chronic glomerulonephritis and was on maintainence hemodialysis.
Bilateral open nephrectomy was performed as hypertension was
uncontrollable with six drugs. He had also been treated for
pulmonary tuberculosis a year earlier. He underwent live related
renal transplantation. The immediate 2 months posttransplant
were uneventful. The patient was put on routine immunosuppres-
sion with cyclosporine, mycophenolate mofetil, and prednisolone.
There was no rejection or infection. Blood pressure was well
controlled on two drugs. His urine output was about 2 L and the
serum creatinine was 1 mg/dL.
The patient then developed fever, which persisted over 45 days.
Initially a urine culture grew E. coli, and antibiotics were adminis-
tered as per sensitivity to sterilize the urine. When fever persisted
despite the antibiotic cover, treatment was extended to include
antituberculous drugs, voriconazole and gancyclovir. A vigorous
survey for an infective focus included blood cultures, bone marrow
aspiration, X-rays, and CT scans of chest and abdomen as well as
CSF studies. Subsequently, the patient developed oliguria, which
progressed to anuria and an increased serum creatinine. Doppler
ultrasound of the graft showed a mild increase in the resistive index
and few debris floaters in the calyces. Graft biopsy performed twice
only showed mild acute tubular necrosis (ATN) and no rejection.
This combination of fever and anuria was not responsive to
intensive antibiotics, daily dialysis, or other supportive measures
over the ensuring 2 weeks. Causes thought to be missed included
