Severe cytomegalovirus enterocolitis developing following daratumumab exposure in three patients with multiple myeloma

Abstract

Novel myeloma treatments prolong patient survival and more patients with profound immunosuppression following multiple lines of therapies are seen in clinical practice. These patients may present with opportunistic infections that were rare in the past. Our findings suggest a possible association between daratumumab therapy (in combination with other immunosuppressive therapies) and severe CMV gastrointestinal disease. A longer follow-up is needed to explore long-term side effects of novel agents like daratumumab in newly diagnosed as well as heavily pretreated MM patients.
