Summary
Recurrence of IgA nephropathy (IgAN) after kidney transplant can cause graft failure. Clinical and histological features of recurrent IgAN are still unclear, but proteinuria and fibrosis are linked to dysfunction.
Area of Science:
- Nephrology
- Transplantation Immunology
- Pathology
Background:
- Recurrence of IgA nephropathy (IgAN) is a significant cause of kidney graft dysfunction and failure over time.
- Limited data exists on the specific clinical and histological characteristics associated with recurrent IgAN post-transplantation.
Purpose of the Study:
- To review existing English literature on recurrent IgAN after kidney transplantation.
- To describe the authors' clinical experience with recurrent IgAN.
- To identify clinical and histological features associated with graft dysfunction in recurrent IgAN.
Main Methods:
- Systematic review of English literature on recurrent IgAN.
- Analysis of clinical data from the authors' own patient cohort.
Main Results:
- The clinical and histological features predicting IgAN recurrence remain indeterminate.
- Proteinuria, glomerulosclerosis, mesangial proliferation, glomerular crescents, and interstitial fibrosis are associated with graft dysfunction in recurrent IgAN.
Conclusions:
- While specific predictive features are still unclear, several histological and clinical markers are linked to graft dysfunction in recurrent IgAN.
- Further research is needed to better understand and predict IgAN recurrence to improve long-term graft survival.
