IgA nephropathy at two score and one

On May 26-28, 2009, an international symposium on IgA nephropathy was convened in Stresa, Italy, as a Satellite Symposium of the World Congress of Nephrology held in Milan. This meeting was attended by a large number of scientists and clinicians working in the field of IgA nephropathy. The oral and poster presentations (over 70) ranged from very fundamental structural biology to clinical management. This article attempts to summarize the main findings of the meeting and to put forth some new perspectives and hypotheses regarding human IgA nephropathy on the 41st anniversary of its original description by Berger and Hinglais in 1968.
