The role of graft-versus-host disease in haematopoietic cell transplantation-associated glomerular disease.

BACKGROUND

Glomerular disease among haematopoietic cell transplantation recipients has been attributed to chronic graft-versus-host disease. Clinical outcomes of this population may be influenced by the haematopoietic cell transplantation conditioning regimen, donor factors and chronic graft-versus-host disease.

METHODS

In this review, 95 cases of haematopoietic cell transplantation-associated glomerular disease were identified from literature review for analysis. Patient characteristics, the association of chronic graft-versus-host disease with glomerular diseases, and the impact of host and haematopoietic cell transplantation regimen on outcomes were evaluated.

RESULTS

The median onset of glomerular disease from haematopoietic cell transplantation and from cessation of immunosuppressive agents was 15.5 and 1 month, respectively. Although chronic graft-versus-host disease was common among haematopoietic cell transplant recipients with glomerulonephritis (72%), this was no different from that observed in the overall haematopoietic cell transplantation population. Membranous nephropathy and minimal change disease are the most prevalent glomerular diseases among haematopoietic cell transplantation recipients. Chronic graft-versus-host disease, donor factors and haematopoietic cell transplant regimen did not significantly impact outcomes in this study population.

CONCLUSIONS

Pathogenic mechanisms in addition to (or other than) chronic graft-versus-host disease are likely contribute to haematopoietic cell transplantation-associated glomerular disease. Further investigation will be required to delineate clearly the pathogenesis.
