Graft rupture after high-dose intravenous immunoglobulin therapy in a renal transplant patient

Renal infarction associated with low dose intravenous immunoglobulin in a kidney transplant recipient with sepsis: a case report and literature review

Background

The use of human intravenous immunoglobulin gamma (IVIG) is associated with thromboembolic events as a complication. There are few reported cases of renal infarction during IVIG use in the general population, but transplant kidney may be more susceptible to thromboembolic events following IVIG use.

Case presentation

A 41-year-old woman visited with fever and pain at the transplant kidney. Six years ago, she underwent kidney transplantation from a deceased donor. Laboratory and radiologic findings were compatible to septic condition, secondary to acute pyelonephritis. We started antibiotics, inotropics, and IVIG. The patient abruptly developed gross hematuria and urine output decreased to 100 cc/day during IVIG administration. Renal doppler and pathologic findings revealed renal infarction. Oliguria and azotemia persisted and she is undergoing maintenance hemodialysis.

Conclusion

Our case shows that infarction of transplant kidney can be caused by IVIG use in a patient with severe infection. Thus, when using IVIG for kidney transplant patients with high risk of thromboembolic events, we may be careful to prevent the thromboembolic events.

Complication from Desensitization

Sensitization to human leukocyte antigens (HLAs) has been one of the major clinical challenges for successful kidney transplantation. In end-stage renal disease, kidney transplantation provides benefits compared with dialysis in terms of improved patient survival better quality of life, and lower ongoing costs after the first year. Living donor kidney transplantation has an advantage with improved allograft survival, and performed earlier and electively compared with deceased donor transplantation. However sensitized patients are increasing in number on transplant waiting lists, and their prospect of getting a transplant is less than nonsensitized patients due to immunological incompatibility with the donor. Strategy for sensitized patients are listing for a compatible deceased donor transplant or, if they have a living donor, either selecting a kidney exchange program or undergoing a desensitization procedure. Desensitization procedures may be undertaken to increase access to either living or deceased donor transplants, and in some situations may also be employed to facilitate participation in a kidney exchange, in less immunological barrier to be overcome. The question of whether individuals are better off with a desensitization treatment followed by HLA-incompatible living donor transplantation or waiting on the deceased donor kidney transplant list for a compatible transplant has recently been addressed by two large multicenter studies, with conflicting results. A multicenter study from the United States published in the New England Journal of Medicine [365;318 326.2011] concluded that there was a strong survival benefit for sensitized patients undergoing desensitization followed by HLA-incompatible living donor kidney transplant compared with those remaining on the waiting list. Of interest, a second study, published in the Lancet, [389;727 734.2017] found no significant survival advantage for desensitized patients compared with similar patients remaining on the waiting list in the United Kingdom. Controversies still remain regarding how desensitization can be achieved and which techniques are effective and safe.

In this chapter various complications from the desensitization will be dealt with in current use of medications or armamentum.

On the dark side of therapies with immunoglobulin concentrates: the adverse events

Therapy by human immunoglobulin G (IgG) concentrates is a success story ongoing for decades with an ever increasing demand for this plasma product. The success of IgG concentrates on a clinical level is documented by the slowly increasing number of registered indication and the more rapid increase of the off-label uses, a topic dealt with in another contribution to this special issue of Frontiers in Immunology. A part of the success is the adverse event (AE) profile of IgG concentrates which is, even at life-long need for therapy, excellent. Transmission of pathogens in the last decade could be entirely controlled through the antecedent introduction by authorities of a regulatory network and installing quality standards by the plasma fractionation industry. The cornerstone of the regulatory network is current good manufacturing practice. Non-infectious AEs occur rarely and mainly are mild to moderate. However, in recent times, the increase in frequency of hemolytic and thrombotic AEs raised worrying questions on the possible background for these AEs. Below, we review elements of non-infectious AEs, and particularly focus on hemolysis and thrombosis. We discuss how the introduction of plasma fractionation by ion-exchange chromatography and polishing by immunoaffinity chromatographic steps might alter repertoire of specificities and influence AE profiles and efficacy of IgG concentrates.
