The management of membranous nephropathy—an update

In recent decades, several important advances have taken place in the understanding of the pathogenesis underlying membranous nephropathy (MN) that have sparked renewed interest in its management. Four landmark trials in MN and a fifth clinical trial—which was a pilot study—have been published in recent years.
