B-cell clones can produce a monoclonal immunoglobulin, which may be responsible for visceral involvements. Kidney involvement is frequent, affecting 20 to 50% of patients with multiple myeloma. One mechanism underlying this involvement is a dysregulation of the complement alternative pathway, leading to C3 glomerulopathies. We report a patient who had a multiple myeloma, C3 glomerulopathy related to factor H autoantibody, and digital ischemia, who was treated successfully with eculizumab, an anti-complement therapy, without any relapse in 2 years of follow-up.
