Data are presented as mean ± standard deviation, or %. *Concerning immunosuppressive drugs: in non-responders—rituximab, 2; cyclophosphamide, 2; melphalan, 1: on going. Calcineurin inhibitors, 2: stopped (24 and 31 months ago). In responders—calcineurin inhibitors, 5 (with mycophenolic acid in 2); mTOR inhibitors, 1; azathioprine, 1: all stopped (mean time since withdrawal: 36 ± 29 months).
