Recurrent IgA nephropathy after renal transplantation despite immunosuppressive regimens with mycophenolate mofetil.

Background: Transplantation offers an excellent option for patients with immunoglobulin-A nephropathy (IgAN) with severe renal dysfunction. However, IgAN frequently recurs in allografts treated with azathioprine. We examined the impact of mycophenolate mofetil immunosuppression on recurrence of IgAN.

Racial differences in parathyroid hormone levels in patients with secondary hyperparathyroidism.

Aim: African-Americans (AA) with normal renal function have higher parathyroid hormone (PTH) levels than Caucasians (C). This difference was also noted in cross-sectional studies of patients on dialysis. In this study, we evaluated patients with end-stage renal disease who have just began dialysis and who were not receiving any vitamin D therapy.
