Invasive aspergillosis remains a problem in solid organs and haematopoietic stem cell transplants. We report a case of 12-year-old female with primary hyperoxaluria with regular haemodialysis for the end-stage renal disease. She underwent a combined liver and renal transplantation which got infected by aspergillosis. In this case study, it is speculated that the most likely source of Aspergillus was contaminated preservative solution (perfusate), resulting in infection within the donor kidney and subsequent systemic infection in the recipient. This case study calls for critical analysis and needs for the routine culture of the preservative solution before transplantation, to detect any fungal contamination and manage it prophylactically.

| ~ Introduction|| |
Invasive aspergillosis remains a problem in solid organ and haematopoietic stem cell transplants. The incidence varies from 1% to 15% and carries a high mortality. Most of the infections occur in the setting of graft versus host disease or during use of steroids or intense immunosuppressant's to prevent rejection. Invasive aspergillosis in the immediate post-operative period after solid organ transplantation is commonly seen in the 1st 2 months with an attributable mortality of around 30%–100%. We hereby describe a case of acquired aspergillosis, possibly due to contamination of perfusate solution of the donor kidney.
| ~ Case Report|| |
A 12-year-old female with primary hyperoxaluria who had been on regular haemodialysis for end-stage renal disease underwent a combined liver and renal transplant (the usual protocol for this disease). The donor for both the liver and kidney was a patient who was brain dead patient following a road traffic accident and had developed Acinetobacter post-traumatic meningitis. He had a prolonged 30-day stay in the intensive care unit and had received broad-spectrum antibiotics but not steroids. Blood, urine and bronchoalveolar lavage cultures were sterile at the time of organ harvest. His other kidney was transplanted to a recipient in another hospital, who at 6 months was doing well and has had no untoward events.
The intraoperative time for this combined transplant procedure was 13 h. The recipient was on regular haemodialysis intra- and post-operatively to keep oxalate levels under control. She received methylprednisolone and basiliximab as an immune-suppressants. On post-operative day (POD) 3, the patient had pain in the right iliac fossa, and an ultrasound revealed a pelvic haematoma for which she was re-explored, and haematoma was evacuated. She was on broad-spectrum antibiotics (colistin and teicoplanin) for possible bacterial sepsis till POD 7.
On POD 8, she developed painful nodular swellings on the right thigh and low-grade fever. A biopsy was performed, and liposomal amphotericin was started on suspicion of a fungal infection. The biopsy revealed septate hyphae consistent with Aspergillus [Figure 1]. Voriconazole was added to liposomal amphotericin.
As she became anuric, she underwent a renal biopsy which was suggestive of acute cortical necrosis following which a transplant nephrectomy on POD 13 was carried out. Histopathological examination of the graft nephrectomy specimen showed extensive ischaemic necrosis with hilar vessels showing subacute inflammation and necrosis with fungal elements, consistent with invasive aspergillosis [Figure 2]. Cultures of the renal vessels, renal incision site and thigh tissue all grew Aspergillus fumigatus [Figure 3].

She further underwent right leg fasciotomy due to compartment syndrome on POD 14 and finally underwent right leg above knee amputation on POD 16. Despite these measures, she continued to have a fever and spread of ischaemia above her waist to the opposite side. She subsequently became haemodynamically unstable and expired on POD 24. Hepatic function and hepatic vascular flow were intact throughout.
| ~ Discussion|| |
Donor-transmitted aspergillosis is not uncommon with one case report where a donor infected with Aspergillus transmitted the organism to three recipients via three allografts (two kidneys and one heart). In another case report, five recipients (two kidneys, one liver, one heart and one islet cell) received organs from a donor whose cause of death on autopsy was found to be invasive aspergillosis of the brain. The kidney recipient lost the renal graft due to invasive aspergillosis, the lung recipient died due to some unknown infection, and the others did well after the initiation of antifungals.
In our case, it is unlikely that the donor had infected organs. The recipient of the other transplanted kidney was doing well with no evidence of fungal infection 6 months later. Airborne acquisition was also unlikely, as our patient had vascular invasion only of the transplanted kidney and no lung, sinus or neurological involvement.
Our patient developed vascular invasion of her transplanted kidney by A. fumigatus, and further developed arterial invasion along the right lower limb. We speculate that the most likely source of Aspergillus was contaminated preservative solution, resulting in infection within the donor kidney and subsequent systemic infection in the recipient. Although a culture of the perfusate solution was not performed in our case, these are known to be an excellent media for the growth of microorganisms. During harvesting, organs can become infected during transportation while hypothermic, while being continuously perfused or during the re-warming stage without perfusion. A prospective study between 2004 and 2008 demonstrated 21 samples out of 659 perfusate solutions were positive for yeasts. Two cases of invasive aspergillosis in cadaveric renal transplants involving the vasculature (as in our case) were most likely due to contamination during preservation of the kidney. The transplanted liver and heart did not show any evidence of aspergillosis, suggesting that the source was preservation. Both these patients had involvement of their right lower limbs causing decreased arterial pulsations.
Other factors such as use of methylprednisolone and basiliximab, intra- and post-operative haemodialysis and operative time more than 11 h (13 h) may have contributed to the fulminant course in this patient, despite antifungal therapy.,, Recipients who are on haemodialysis are 15–25 times more at risk for invasive fungal infections. Other risk factors recognised are CMV infection and use of large amounts of fresh frozen plasma.,
| ~ Conclusion|| |
We recommend that the perfusate should also be routinely cultured before transplantation, apart from the routine evaluation of donor so that if contamination is documented early, then the antifungal prophylaxis in the recipient can be initiated.
