    Abstract:
    We discuss a renal transplant patient with recurrent IgA nephropathy (IgAN) before and after tonsillectomy. A 36-year-old man started on hemodialysis support in 1996 due to biopsy-proven IgAN, living related renal transplantation was then performed in 1997. Six years after transplantation, the patient presented with microhematuria and proteinuria. Graft biopsy for these urinary abnormalities showed recurrent IgAN. Tonsillectomy was subsequently performed in December 2003, proteinuria remitted 6 months after the tonsillectomy and microhematuria disappeared three years later. Protocol graft biopsy was subsequently performed twice, at 2 yr after the tonsillectomy (2005) and 4 yr after (2008). Comparing the findings of the pre-tonsillectomy biopsy and the two post-tonsillectomy biopsies, an increase in mesangial cells and matrix in 2005, and an expansion of the mesangial matrix and proliferation of mesangial interposition in 2008. In addition, global sclerosis of glomeruli increased over time, the area of tubulointerstitial damage has extended as well. While the tonsillectomy led to clinical remission of recurrent IgAN, the chronicity progressed on these protocol biopsies. This is the first report of the efficacy and the limitations of tonsillectomy in a case of recurrent IgAN in a transplant patient.
