PPAR agonists in diabetic nephropathy
Email: peter.gross{at}mailbox.tu-dresden.deSir,
A recent Editorial Comment (Nephrol Dial Transplant 2006; 21: 26962702) considered the role of PPAR agonists in diabetic nephropathy; it also addressed other nephropathies. In the former category, in the section on observations in humans, the authors comments are almost exclusively limited to UAE (urinary albumin excretion rate) before and after thiazolidinedione. In terms of kidney function this is a kind of black-box approach, since nobody knows for sure by which molecular or cellular changes UAE comes about. We missed comments by the authors on intrarenal haemodynamic effects of thiazolidinediones in this respect. The authors did not mention recent studies, published in Diabetes Care and Diabetes, on these issues by our group. We believe that an editorial comment ought to be fair in giving a careful and well balanced view of the published literature.
