摘要

Treatment of malignant lymphoma, multiple myeloma, and acute lymphatic leukemia with bispecific antibodies is established. The most important side effect is sustained immunosuppression due to lymphopenia, neutropenia, and hypogammaglobulinemia. Infections with a wide spectrum of pathogens contribute significantly to morbidity and mortality. Febrile neutropenia and bacterial infections of the respiratory tract are most frequent. Due to the considerable cellular immunosuppression, infections with classical opportunistic pathogens such as Pneumocystis jirovecii, herpes simplex virus, varicella zoster virus, Toxoplasma gondii (toxoplasmosis), or the cytomegalovirus are of highest relevance. The current article provides an overview of the frequency of infectious complications during treatment with bispecific antibodies and elaborates on predisposing risk factors. Measures for infection screening and possible drug-based primary prophylaxis are discussed.
