[Plasma exchange in nephrology].

Plasma exchange is often prescribed in nephrology and represents a technical as well as logistic challenge. It is thus important to master its most frequent indications. In this narrative review, we discuss main diseases requiring therapeutic plasma exchange in nephrology: anti-glomerular basement membrane disease, thrombotic microangiopathy as well as various clinical scenarios in kidney transplant. We also review plasma exchange in ANCA associated vasculitis, where indications have recently been restricted owing to recent scientific evidences.
