[Lupus nephritis and associated thrombotic microangiopathy].

Lupus nephritis represents the most common manifestation of lupus of the solid organs and is associated with an increased risk of chronic kidney disease. The co-occurrence of lupus nephritis and thrombotic microangiopathy is described to be rare but implies the risk of fatal organ dysfunction. We report three patients in whom these two disease entities occurred in parallel, necessitating intensive immunosuppressive therapy, including complement blockade.
