Association Between Immunoparesis and Treatment Outcomes of Patients With Newly Diagnosed Multiple Myeloma: A Systematic Review and Meta-Analysis.

Background: Immunoparesis, defined as suppression of uninvolved polyclonal immunoglobulins, occurs in up to 80% of patients with newly diagnosed multiple myeloma (NDMM). Infections are the second most common cause of mortality in this population, yet evidence regarding prognostic impact of immunoparesis in NDMM remains unclear.

Materials And Methods: Using a prepublished protocol (CRD42022308687), we searched seven bibliographic databases from inception to February 2023 for studies reporting the impact of immunoparesis on clinical outcomes among adults with NDMM.
