Effective treatment of refractory monoclonal gammopathy-associated pure red cell aplasia with isatuximab, pomalidomide and dexamethasone

Abstract

Monoclonal gammopathy-associated pure red cell aplasia (MG-PRCA) is characterized by the absence or pronounced hypoplasia of erythroid precursors in the bone marrow, causing reticulocytopenia and a normocytic, normochromic anaemia in a patient with a monoclonal plasma cell dyscrasia. We report here on the successful treatment of MG-PRCA with isatuximab, pomalidomide, and dexamethasone after multiple lines of immunosuppressive and anti-plasma cell-directed treatments.
