Abstract
OBJECTIVE Multiple myeloma (MM) varies in clinical behavior, response to treatment and prognosis due to the heterogeneity of the disease. Data on the association between the immunoparesis status during treatment and prognosis in nontransplant MM patients are limited. METHODS In a retrospective analysis of 142 patients with MM, we examined the relationship between immunoparesis status and prognosis during treatment. All patients received novel agent-based therapy and did not undergo autologous stem cell transplantation. One, two, or three uninvolved immunoglobulins (Igs) below the lowest thresholds of normalcy were used to identify immunoparesis. RESULTS Patients with a greater degree of immunoparesis during treatment had shorter progression-free survival (PFS) and overall survival (OS). A total of 46.5% of the patients had severe and continuous immunoparesis (at least two uninvolved Igs suppressed continuously during treatment), representing a worse prognosis than those with complete or partial normalization of Igs during treatment. Among patients who achieved at least complete remission, PFS was poor in patients with severe and continuous immunoparesis. Furthermore, severe and continuous immunoparesis during treatment was a poor prognostic factor for PFS and OS according to multivariate analyses. CONCLUSION The degree of immunoparesis during treatment is a follow-up indicator for survival in nontransplant myeloma patients, and severe and continuous immunoparesis in nontransplant myeloma patients might be a sign of poor prognosis.

Laboratory and Clinical Settings of Heavy/Light Chain (HLC) Assays in the Management of Monoclonal Gammopathies and Multiple Myeloma. J Pers Med 2023; 13:jpm13050743.

Abstract
The antibody-related immune response is mediated by immunoglobulins (Igs), soluble circulating glycoproteins produced by activated B cells that, upon the recognition of specific epitopes on pathogen surfaces, activate, proliferate, and differentiate into antibody-secreting plasma cells. Although the antibodies are effectors of the humoral immune adaptive response, their overproduction in response to a dysregulated proliferation of clonal plasma cell production in tumoral conditions (i.e., multiple myeloma), enriches the serum and urinary matrices, assuming the crucial role of biomarkers. Multiple myeloma (MM) is a plasma cell dyscrasia characterized by the expansion and accumulation of clonally activated plasma cells in bone marrow, determining the release of high amounts of monoclonal component (MC) that can be detected as intact immunoglobulin (Ig), immunoglobulin fragments, or free light chains (FLCs). The importance of detecting biomarkers for the diagnosis, monitoring, and prognosis of diseases is highlighted by the international guidelines that recommend specific assays for the analysis of intact Igs and FLC. Moreover, a developed assay called Hevylite® allows for the quantification of immunoglobulins that are both involved (iHLC) and not involved (uHLC) in the tumor process; this is a fundamental aspect of following up the patient's workup and evaluating the progression of disease, together with the treatments response. We here summarize the major points of the complex scenario involving monoclonal gammopathies and MM clinical management in view of advantages derived for the use of Hevylite®.

The Current Role of the Heavy/Light Chain Assay in the Diagnosis, Prognosis and Monitoring of Multiple Myeloma: An Evidence-Based Approach. Diagnostics (Basel) 2021; 11:diagnostics11112020. [PMID: 34829367 PMCID: PMC8620453 DOI: 10.3390/diagnostics11112020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2021] [Revised: 10/27/2021] [Accepted: 10/27/2021] [Indexed: 11/17/2022] Open
Abstract
Despite tremendous progress being made in recent years, multiple myeloma (MM) remains a challenging disease. The laboratory plays a critical role in the overall management of patients. The diagnosis, prognosis, clinical monitoring and evaluation of the response are key moments in the clinical care process. Conventional laboratory methods have been and continue to be the basis of laboratory testing in monoclonal gammopathies, along with the serum free light chain test. However, more accurate methods are needed to achieve new and more stringent clinical goals. The heavy/light chain assay is a relatively new test which can overcome some of the limitations of the conventional methods for the evaluation of intact immunoglobulin MM patients. Here, we report an update of the evidence accumulated in recent years on this method regarding its use in MM.
