Recurrence of monoclonal IgA lambda glomerulonephritis in kidney allograft associated with multiple myeloma.

Proliferative glomerulonephritis with monoclonal immunoglobulin deposits (PGNMID) has been described as a new entity resembling immune-complex glomerulonephritis (GN). The recurrence of proliferative GN with monoclonal IgG in the renal allograft has been reported. However, recurrence of proliferative GN with monoclonal IgA after renal allograft is undefined.

BK nephropathy in kidney transplant recipients treated with a calcineurin inhibitor-free immunosuppression regimen.

Recently, polyomavirus-associated nephropathy (PVAN) has been reported more frequently and is emerging as an important cause of renal allograft dysfunction and graft loss. Susceptibility appears to be related to the type and intensity of pharmacologic immunosuppression but some reports have suggested a link among the development of PVAN, the treatment of rejection or maintenance with a tacrolimus-based immunosuppressive regimen. We report three cases of PVAN in patients who never received immunosuppression with calcineurin inhibitors (CNIs).

Lymphedema associated with sirolimus in renal transplant recipients.

Lymphoceles are common in renal transplant recipients who receive sirolimus (SRL). However, a recent MEDLINE search revealed no reports of lymphedema related to SRL. We describe three cases of lymphedema that resolved or improved on discontinuation of SRL.

Creatinine reduction ratio and 24-hour creatinine excretion on posttransplant day two: simple and objective tools to define graft function.

To devise objective criteria for early diagnosis of delayed graft function (DGF), 59 adult living donor kidney transplants with immediate graft function (IGF) and 51 cadaveric kidney transplants were investigated for creatinine reduction ratio (CRR2) from posttransplant day 1 to day 2 and 24-h urine creatinine excretion (UC2) on day 2. The mean CRR2 in living donor transplants was 53% (SD +/- 11); the distribution of CRR2 was gaussian, and all of them had UC2 >1000 mg. Criteria for DGF were developed on the basis of living donor transplant: CRR2 < or =30% (2SD below 53%) +/- UC2 < or =1000 mg.
