Abstract

Abstract: Background and Aims: Intravenous immunoglobulins (IVIG) are pooled polyvalent IgG antibodies extracted from the human plasma. While the initial indications were mainly immune deficiency states and some autoimmune diseases, the usage has been widened to include several immune mediated diseases, viral infections, and organ transplant rejection. Stabilizers in IVIG may include sugars, such as sucrose, glucose, or maltose. Sucrose in IVIG preparations may cause acute kidney injury. We report the case of a renal transplant patient who developed acute kidney injury due to sucrose nephropathy following the administration of sucrose containing IVIG. Method: Four months after transplantation he was referred to our Hospital for deterioration of kidney function with eGFR (by MDRD formula) of 27ml/min. Cytomegalovirus virus (CMV) PCR turned positive (3300 copies/ml). Cyclosporine levels were high (C2: 2937 ng/ml) and hence, cyclosporine dose was adjusted. Induction therapy with Injection Ganciclovir for 2 weeks, followed by therapeutic dose of oral Valganciclovir was administered for the treatment of CMV infection. Skin examination revealed annular purple patches, suspicious of Kaposi Sarcoma, on the upper limbs. Skin biopsy confirmed the diagnosis. It was planned to give total IVIG of 2 gm/ kg in four daily divided doses. After completion of the second dose, serum creatinine increased to 370 µ mol/L. He was clinically asymptomatic, euvolumic, vital signs were stable, and his urine output remained normal and his urinalysis was inactive. Results: The ultrasound of the transplant kidney was normal with normal resistivity index. IVIG was stopped. He was well hydrated and underwent ultrasound guided biopsy. The graft biopsy showed acute tubular injury with flattening and vacuolation of tubular epithelial cells. Mitosis indicating tubular regeneration was seen. There was mild focal interstitial inflammation (20%) with mild lymphocytic tubulitis not amounting to graft rejection. Immunohistochemistry for C4d and polyomavirus (BKV) were both negative. The features were most consistent with sucrose induced nephropathy (Figure 1). Subsequent visits showed a decrease in BKV-PCR serum level and eventually undetected serum level of BKV-PCR at follow up about a month later. Conclusion: In this paper, we presented a case of a living unrelated kidney transplant recipient who developed BKV nephropathy and developed impaired kidney function. The patient also had new onset diabetes mellitus after kidney transplantation (NODAT) but was otherwise in good general health. Treatment included sucrose containing IVIG. The patient subsequently developed acute kidney injury. The outcome was favorable with recovery of filtration rate to the baseline within 21 days without the need for dialysis. We conclude that the administration of sucrose containing IVIG may lead to acute kidney injury. We recommend the use of sucrose-free IVIG whenever possible. In all cases, caution is required when administrating IVIG.
