European and American recommendations have recently been published for the treatment of proliferative lupus nephritis (LN). This study aimed to describe current practice in France. An electronic survey was sent to French nephrologists and internists via their scientific society between March and December 2012. One hundred and nine specialists (60 internists, 48 nephrologists and 1 rheumatologist), mostly from hospitals, completed the survey. Low-dose cyclophosphamide (Euro-Lupus) was the first induction immunosuppressive therapy used (67%), followed by mycophenolate mofetil (MMF) (20%) and high dose CYC (NIH, 9%). Maintenance immunosuppressive therapy after an induction with CYC was preferentially MMF (58%), versus 14% for azathioprine (AZA) and 25% using either MMF or AZA without preference. After an induction with MMF, maintenance treatment was mainly MMF (77%). Antimalarial drugs were prescribed systematically by 86% of specialists. In patients in stable remission, maintenance treatment was withdrawn after 2 years (40%), 3 years (25%) or more (34%). Low-dose corticosteroids were continued in the long-term by 54% of specialists. No difference was observed between nephrologists and internists, even in the prescription of antimalarials. Treatment of proliferative LN in France is homogenous enough and is consistent with recent international recommendations.
