Hudier L, et al. – The efficacy (renal recovery rate) of intensive haemodialysis (IHD) and of standard haemodialysis (SHD) in patients with multiple myeloma (MM) and dialysis–dependent acute kidney injury (AKI) was compared. In these patients, the renal benefit of IHD was not evident compared with SHD. This study highlighted the importance of the haematological response to chemotherapy for the renal response and patient prognosis.
