In native kidneys, the majority of the cases corresponded to chronic nephritic syndrome, followed Decitabine datasheet by nephrotic syndrome and recurrent

or persistent hematuria or renal disorder with collagen disease or vasculitis in 2007 (Table 2). Similar frequencies of chronic nephritic syndrome, nephrotic syndrome and renal disorder with collagen disease or vasculitis were observed in 2008 (Table 2).

glomerular disease (except IgAN) and renal grafts both in 2007 and 2008 (Table 3). In the present cohort, except for renal grafts, the frequency of IgAN was 32.9%, followed by primary glomerular disease (except IgAN) (26.3%) and diabetic nephropathy (5.9%) in 2007 (Table 3). A slightly Thiamet G lower frequency of IgAN was present (30.2%), but similar frequencies of primary glomerular disease (except IgAN) (26.3%) and diabetic nephropathy (5.1%) were observed in 2008 (Table 3).
