Should treatment of hypogammaglobulinemia with immunoglobulin replacement therapy (IgRT) become standard of care in patients with chronic lymphocytic leukemia? Front Immunol 2023; 14:1062376. [PMID: 37122737 PMCID: PMC10140292 DOI: 10.3389/fimmu.2023.1062376] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2022] [Accepted: 03/13/2023] [Indexed: 05/02/2023] Open
Abstract
Hypogammaglobulinemia (HGG) is a frequent finding in patients with hematological malignancies, and is commonly described in chronic lymphocytic leukemia (CLL) before or after treatment. We reviewed published literature available online in the last thirty years through Medline search of indexed articles focusing on the main differences and advantages of the products now available on the market, namely intravenous Ig (IVIg) and subcutaneous Ig (SCIg) preparations. IgRT is effective and safe in the prophylaxis of infections in a selected group of patients with CLL and hypogammaglobulinemia and is therefore a valuable tool for clinicians in the everyday management of infectious risk. We encourage the use of SCIg formulations as they appear to have similar efficacy but better cost-effectiveness and tolerability.

Application of cerebrospinal fluid free light chain in diagnosis of primary central nervous system lymphoma and monitoring of associated chemotherapy efficacy. Clin Chim Acta 2022; 533:48-52. [PMID: 35716705 DOI: 10.1016/j.cca.2022.06.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2022] [Revised: 06/06/2022] [Accepted: 06/07/2022] [Indexed: 11/03/2022]
Abstract
BACKGROUND Cerebrospinal fluid (CSF) free light chain (FLC) detection has been proposed as a tool for diagnosing primary central nervous system lymphoma (PCNSL), but there is no consensus on the appropriate reference range and its value for monitoring chemotherapy efficacy has not been investigated in Chinese PCNSL patients. We assessed the application potential of CSF FLC ratios for diagnosing PCNSL and monitoring associated treatment efficacy. METHODS Kappa (κ) and lambda (λ) FLC were measured by nephelometry in CSF samples of patients with PCNSL (n = 45), other neurological diseases (n = 30), and normal controls (n = 60). Results of κ/λ FLC ratios (FLCr) were correlated with patients' diagnoses and receiver operating characteristic analysis was used to determine accuracy. In PCNSL patients, FLCr analysis was compared between PCNSL before and after treatment. RESULTS κ FLC and FLCr concentrations in PCNSL were significantly higher than in patients without PCNSL (P < 0.05). The optimal cut-off for FLCr was 0.35, with diagnostic sensitivity and specificity of 78% and 72%, respectively. FLCr concentrations decreased after chemotherapy. CONCLUSION CSF FLC is a novel biomarker for diagnosis and chemotherapy efficacy monitoring in PCNSL.

Abstract
Chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) is a monoclonal B cell lymphocytosis that produces nephrotoxic monoclonal immunoglobulin (MIg). However, the role of MIg in CLL and how it affects CLL patient survival are still unknown. Here, we report a case of MIg with renal significance (MGRS) associated with CLL. A 59-year-old Chinese woman complaining of abdominal pain, skin purpura, and typical soy-colored urine was admitted to the hospital for investigation. Laboratory tests revealed that she had microangiopathic hemolytic anemia, thrombocytopenia, acute kidney injury (AKI), and hypocomplementemia. She also reported cryoglobulinemia, thrombotic microangiopathy (TMA), and AKI 2 years previously. Peripheral blood smears at that time showed 4% schistocytes, a negative Coombs' test, and elevated lactate dehydrogenase (LDH). Based on a diagnosis of complement-mediated TMA, the patient was treated by plasmapheresis and achieved clinical disease remission. However, the serum hypocomplement 4 and cryoglobulinemia persisted. Further investigation showed elevated B lymphocytes and monoclonal serum IgMκ; however, the cryoprecipitate contained monoclonal IgMκ and polyclonal IgG, as well as immunoglobulins κ and λ. After plasmapheresis, her LDH, platelets, and complement 3 (C3) levels returned to normal. Biopsies of the bone marrow and an enlarged subclavicular lymph node revealed CLL/SLL. Renal pathological findings indicated significant arteriolar endothelial cells myxoid edema and glomerular endothelial cells swelling, however no thromboli, cryoglobulin formation and vasculitis were observed. We also found mild mesangial proliferative C3 glomerulonephritis and renal interstitial CLL cells infiltration. Collectively, these clinical and pathological manifestations were attributed to monoclonal IgMκ, which triggered C3 activation. MGRS associated with CLL was finally confirmed. Six cycles of rituximab, cyclophosphamide, verodoxin, and dexamethasone therapy were administered, after which she received ibrutinib. The patient experienced disease remission, and her serum C4 level returned to normal. Cryoglobulin and IgMκ were not detected. This is a special presentation of CLL/SLL with monoclonal IgMκ, which is a type of MGRS. Activation of the complement system by MIg led to TMA with C3 glomerulonephritis. Treatment for TMA and CLL/SLL should be initiated in a timely manner to improve patient prognosis.

Abstract
Background Patients with chronic lymphocytic leukemia (CLL) experience hypogammaglobinemia and non-neutropenic infections. In this exploratory proof of concept study, our objective was to determine the prevalence of humoral immunodeficiency in patients with CLL and serum IgG ≥ 400 mg/dL, and to evaluate the efficacy of subcutaneous immunoglobulin (SCIG) in this population. Patients and methods Patients with CLL with serum IgG ≥ 400 mg/dL were evaluated for serum IgG, IgM, IgA, along with pre/post vaccine IgG titers to diphtheria, tetanus, and Streptococcus pneumoniae. Patients with evidence of humoral dysfunction were treated with SCIG with Hizentra every 7±2 days for 24 weeks. Results Fifteen patients enrolled with median IgG = 782 mg/dL [IQR: 570 to 827], and 6/15 (40%) responded to vaccination with Td, while 5/15 (33%) responded to vaccination with PPV23. 14/15 (93.3%) demonstrated humoral immunodeficiency as evidenced by suboptimal vaccine responses, and were treated with SCIG. In patients treated with SCIG, serum IgG increased from 670 mg/dL [IQR: 565 to 819] to 1054 mg/dL [IQR: 1040 to 1166] after 24 weeks (95% CI: 271–540). For streptococcus pneumoniae, the median protective serotypes at baseline was 8 [IQR: 4 to 9] and increased to 17 [IQR: 17 to 19] after 24 weeks (95% CI: 6.93–13.72). Non-neutropenic infections (NNI) decreased from 14 to 5 during treatment with SCIG. Conclusions Patients with CLL demonstrate humoral immunodeficiency despite IgG > 400 mg/dL. For these patients, SCIG is well tolerated and efficacious in improving serum IgG, specific IgG to streptococcus pneumoniae, and may decrease reliance on antibiotics for the treatment of NNIs. Clinical trials registration NCT 03730129.

Flow cytometry detection of CD138 expression continuum between monotypic B and plasma cells is associated with both high IgM peak levels and MYD88 mutation and contributes to diagnosis of Waldenström macroglobulinemia. CYTOMETRY PART B-CLINICAL CYTOMETRY 2021; 102:62-69. [PMID: 33634586 DOI: 10.1002/cyto.b.21995] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/24/2020] [Revised: 01/13/2021] [Accepted: 02/08/2021] [Indexed: 01/02/2023]
Abstract
BACKGROUND Differential diagnosis of Waldenström macroglobulinemia (WM) with other indolent B-cell malignancies is still a challenge. Here, we propose an original and simple analysis of routine flow cytometry (FCM) unraveling the characteristic ongoing plasma cell (PC) differentiation of WM tumor B-cells. METHODS FCM analysis of both B-cells and PC was performed on a series of 77 patients with IgM peak. MYD88 and CXCR4 mutations were studied using an allele-specific PCR and by high throughput sequencing. RESULTS Twenty seven (35%), 46 (58%) and 4 (5%) patients were classified as WM, IgM monoclonal gammopathy of undetermined significance (MGUS) or other B-NHL respectively. MYD88 mutation was found in 25/27 WM (93%) and in 29/46 MGUS (63%). Using FCM, monotypic B-cells were found in 27/27 WM (100%) and 34/46 MGUS (74%). Monotypic CD138pos/CD38pos PCs were detected in 23/27 WM (85%) and 25/46 MGUS (54%). Highlighting the ongoing PC differentiation of WM tumor B-cells by FCM, we evidenced a CD138 expression continuum between monotypic B-cells and PCs. This pattern remained absent in control samples and was significantly associated with higher IgM peaks (p = 6.10-5 ) and MYD88 mutations (p = 10-3 ) in both WM and MGUS cases. CONCLUSIONS FCM exploration of both B-cells and PC led to identify a CD138 expression continuum as an objective marker of ongoing PC differentiation of WM tumor cells and was strongly associated with increased IgM peak levels and MYD88 mutations. This approach could contribute to place FCM at the forefront of WM diagnosis.

Transpl Immunol 2019; 57:101229. [PMID: 31398462 DOI: 10.1016/j.trim.2019.101229] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2019] [Revised: 07/31/2019] [Accepted: 08/04/2019] [Indexed: 01/15/2023]
Abstract
BACKGROUND Posttransplant lymphoproliferative disorder (PTLD) is a severe complication of solid organ transplantation (SOT). However, there is no consensus on PTLD screening methods. Gammopathies (GP), which occur in 10-25% of SOT recipients, have been linked to subsequent development of PTLD. Therefore, GP detection methods, such as serum protein electrophoresis (SPE), serum protein immunofixation (SIFE), urine protein immunofixation (UIFE) and the quantitative measurement of serum free light chains (SFLC) are candidate methods for PTLD screening. OBJECTIVE We aimed to assess the frequency of PTLD and GP, association of GP with subsequent PTLD, allograft loss or death and the diagnostic performance of SPE/SIFE in PTLD screening. The main objective was to explore, whether GP detection methods can be used to enhance the efficiency of PTLD screening and to formulate a concise algorithm for posttransplantation (post-Tx) follow-up. METHODS We performed a cohort study on 1677 SOT recipients with SPE/SIFE data who underwent kidney, liver, heart, pancreas, Langerhans islets or multiple organ transplantation at the Institute of Clinical and Experimental Medicine between 1966 and 2015. The median (IQR) of follow-up time was 8.0 (4.0-12.0) years. RESULTS The frequencies of PTLD and GP in SOT recipients were 2.8% and 6.4%, respectively. The frequencies of transient GP, GP of undetermined significance and malignant GP were 33%, 63% and 4% respectively. The median time between SOT and GP detection was 2.0 (interquartile range 1.0-7.0) years. GP was associated with a significantly higher risk of PTLD, allograft loss and death, with hazard ratios (95% confidence intervals) of a 6.06 (2.51-14.64), 2.61 (1.49-4.6) and 1.99 (1.2-3.3), respectively. Additionally, GP was associated with 2.98-fold increased risk of allograft loss in kidney transplant patients. SPE diagnostic sensitivity and specificity for PTLD were 14.8% and 93.9%, respectively. PTLD was diagnosed more often and earlier if SPE/SIFE was included in the post-Tx follow-up. CONCLUSIONS GP after SOT is associated with a high risk of PTLD, allograft loss and poor survival. The combination of SPE, SIFE, SFLC and UIFE is optimal for GP detection. These methods aid in identifying patients who are at risk for PTLD or allograft damage and should be included in regular post-Tx follow-up.

Abstract
Chronic lymphocytic leukemia (CLL) and its precursor, monoclonal B-cell lymphocytosis (MBL), are heritable. Serumfree light-chain (sFLC) measures are a prognostic factor for CLL, but their role in susceptibility to CLL is not clear. We investigated differences between sFLC measurements in pre-treatment serum from five groups to inform the association of sFLC with familial and sporadic CLL: (1) familial CLL (n = 154), (2) sporadic CLL (n = 302), (3) familial MBL (n = 87), (4) unaffected first-degree relatives from CLL/MBL families (n = 263), and (5) reference population (n = 15,396). The percent of individuals having elevated monoclonal and polyclonal sFLCs was compared using age-stratified and age- and sex-adjusted logistic regression models. In age groups >50 years, monoclonal sFLC elevations were increased in sporadic and familial CLL cases compared to the reference population (p's < 0.05). However, there were no statistically significant differences in sFLC monoclonal or polyclonal elevations between familial and sporadic CLL cases (p's > 0.05). Unaffected relatives and MBL cases from CLL/MBL families, ages >60 years, showed elevated monoclonal sFLC, compared to the reference population (p's < 0.05). This is the first study to demonstrate monoclonal sFLC elevations in CLL cases compared to controls. Monoclonal sFLC levels may provide additional risk information in relatives of CLL probands.

Abstract
Monoclonal gammopathy (MG), a positive result of serum immunofixation electrophoresis (SIFE), has been reported in cases of diffuse large B-cell lymphoma (DLBCL). We performed this study to further investigate the prognostic value of MG in DLBCL.We retrospectively reviewed patients diagnosed with DLBCL between January 2007 and December 2014, and identified 37 patients with MG. The clinical characteristics of these patients were then reviewed. A 1:2 case-control analysis was conducted on 74 matched controls, who were patients with DLBCL and without MG. Both cases and controls were age-matched and were diagnosed within the same year.Among 37 DLBCL patients with MG, the monoclonal component of IgM was the most frequent compared to the other subtypes. Laboratory tests showed that the presence of MG was correlated with a decreased platelet-to-lymphocyte ratio (PLR). Survival analysis showed that MG-secreting DLBCL patients had an inferior overall survival (OS) and progression-free survival (PFS), compared with MG-nonsecreting patients, regardless of MG subtype. However, treatment response analysis showed that MG was not a good indicator for tumor relapse. When patients with DLBCL were grouped by immunophenotype, we found that MG was associated with poor prognosis in the non-germinal center B-cell-like (GCB) type, rather than GCB type in OS analysis. Meanwhile, there was no statistical significance upon PFS analysis in both immunophenotypes. Furthermore, our study found that the appearance of MG during treatment did make prognostic sense compared to nonsecretors.Overall, MG can serve as a prognostic factor for DLBCL. We hypothesize that its presence in DLBCL may reflect the immune microenvironment in tumor progression and warrants further study to unveil the underlying molecular pathogenesis.

Abstract
More than 35 years after the Binet classification, there is still a need for simple prognostic markers in chronic lymphocytic leukemia (CLL). Here, we studied the treatment-free survival (TFS) impact of normal serum protein electrophoresis (SPE) at diagnosis. One hundred twelve patients with CLL were analyzed. The main prognostic factors (Binet stage; lymphocytosis; IGHV mutation status; TP53, SF3B1, NOTCH1, and BIRC3 mutations; and cytogenetic abnormalities) were studied. The frequencies of IGHV mutation status, cytogenetic abnormalities, and TP53, SF3B1, NOTCH1, and BIRC3 mutations were not significantly different between normal and abnormal SPE. Normal SPE was associated with Binet stage A, nonprogressive disease for 6 months, lymphocytosis below 30 G/L, and the absence of the IGHV3-21 gene rearrangement which is associated with poor prognosis. The TFS of patients with normal SPE was significantly longer than that of patients with abnormal SPE (log-rank test: P = 0.0015, with 51% untreated patients at 5.6 years and a perfect plateau afterward vs. a median TFS at 2.64 years for abnormal SPE with no plateau). Multivariate analysis using two different Cox models and bootstrapping showed that normal SPE was an independent good prognostic marker for either Binet stage, lymphocytosis, or IGHV mutation status. TFS was further increased when both normal SPE and mutated IGHV were present (log-rank test: P = 0.008, median not reached, plateau at 5.6 years and 66% untreated patients). A comparison with other prognostic markers suggested that normal SPE could reflect slowly advancing CLL disease. Altogether, our results show that a combination of normal SPE and mutated IGHV genes defines a subgroup of patients with CLL who evolve very slowly and who might never need treatment.

Abstract
Lymph node enlargement is a common presentation and has a possibility of malignancy like lymphoma that requires early diagnosis. This study aims to analyze the clinical characteristics of these patients and finds out useful predictors of malignant diseases. We retrospectively investigated 81 patients with lymph node enlargement between July 2, 2014 and May 17, 2016. The characteristics and laboratory findings were evaluated combining with the final diagnosis. The diagnoses were malignancy in 51 patients and benign lymphadenopathy in 30 patients. Increased beta2-microglobulin (B2M) (P = 0.012) was found to be associated with malignant diseases, and level of 3699.5 μg/L was used as a cut-off value to differentiate the malignancies from benign diseases, offering 63.4% sensitivity and 87.0% specificity. Immunoglobulin G (IgG) (P = 0.038) levels were significantly lower in malignant group, whose receiver operating characteristic curve showed that level of 1121.5 mg/dl had sensitivity and specificity as 58.5% and 82.6%. Moreover, through analysis of cytokines, we found interleukin-10 (IL-10) levels were elevated in malignant group compared with benign group. Serum B2M and IgG levels were concluded to be useful parameters for predicting malignancies. Besides, increased IL-10 levels indicated a higher risk of malignancy in some way.

Abstract
Introduction: The serum immunoglobulin free light chain (FLC) assay quantities of free kappa (κ) and lambda (λ) light chains. This assay has prognostic value in plasma cell proliferative disorders. There are limited data on serum FLC in B-cell malignancies.
Objectives: The aim of this study was to compare the known prognostic factors in non-Hodgkin’s lymphoma of the type B-cell and Hodgkin disease with an abnormal secretion amount of light chains in these lymphomas.
Patients and Methods: The association of pretreatment FLC and FLC ratio (κ:λ) with previously known prognostic factors for lymphoma such as the international prognostic index (IPI) and B symptoms were evaluated in 50 patients with Hodgkin’s and non-Hodgkin’s lymphoma. IPI is a prognostic score given based on the clinical variables including age, disease stage, serum LDH and extra-nodal involvement. Elevated FLC and an abnormal κ:λ ratio was defined based on the previous publications.
Results: The prevalence of abnormal FLC ratio was 38% in all patients and 40.9% in patients with diffuse large B-cell lymphoma. Abnormal FLC ratio was significantly associated with IPI (P=0.04) and B symptoms (P=0.02) in both groups of the patients with Hodgkin’s and non-Hodgkin’s lymphoma. The stage of the disease in Hodgkin’s lymphoma patients showed a significant relationship with the abnormal FLC ratio (P=0.04). Presence of the B symptoms in patients with Hodgkin’s lymphoma had a modest but not statistically significant association with the abnormal FLC ratio (P=0.07).
Conclusion: Abnormal FLC ratio as a new potent prognostic biomarker has a significant association with IPI which is the most common clinical tool used to predict outcome in lymphoma patients. Since there is a need for developing a reliable and quantitative prognostic biomarker for lymphoma, evaluation of the independent effect of the abnormal serum FLC ratio is suggested to be considered in future prospective studies. The result of these studies will also be useful for nephrologists, while serum immunoglobulin FLC is capable to damage kidney.

Abstract
There are limited data on serum total light chain (sTLC) in lymphoma and its relative role on the outcome of diffuse large B cell lymphoma (DLBCL) patients. Blood samples from 46 cases newly diagnosed with DLBCL were collected consecutively during chemotherapy to detect sTLC, IgG, IgA, and IgM levels. Clinical data and survival outcomes were analyzed according to the results of sTLC measurements. In summary, 22 patients (47.8 %) had abnormal k or λ light chain, respectively, and 6 patients (13.0 %) had both abnormal k and λ light chains before chemotherapy. Patients with elevated k light chain more frequently displayed multiple extra-nodal organ involvement (P = 0.01) and had an inferior overall survival (OS) (P = 0.041) and progression-free survival (PFS) (P = 0.044) compared to patients with normal level of k light chain. Furthermore, patients with elevated level of both k and λ also exhibited significant association with shorter OS (P = 0.002) and PFS (P = 0.009). Both elevated k alone and concurrent elevated k and λ had independent adverse effects on PFS (P = 0.031 and P = 0.019, respectively). sTLC level was reduced gradually by treatment in this study and reached the lowest point after the fourth cycle of chemotherapy, which was consistent with the disease behavior during chemotherapy. Considering the small sample size of this study, these results should be confirmed in a larger prospective study.

Abstract
Infections are a major cause of morbidity and mortality in patients with chronic lymphocytic leukemia (cll), who typically have increased susceptibility because of hypogammaglobulinemia (hgg) related to their disease and its treatment. Immunoglobulin replacement therapy (igrt) has been shown to reduce the frequency of bacterial infections and associated hospitalizations in patients with hgg or a history of infection, or both. However, use of igrt in cll is contentious. Studies examining such treatment were conducted largely before the use of newer chemoimmunotherapies, which can extend lifespan, but do not correct the hgg inherent to the disease. Thus, the utility of igrt has to be re-evaluated in the current setting. Here, we discuss the evidence for the use of igrt in cll and provide a practical approach to its use in the prevention and management of infections.

Abstract
The serum immunoglobulin free light chain (FLC) assay quantitates free kappa (κ) and lambda (λ) light chains. FLC elevations in patients with diffuse large B-cell lymphoma (DLBCL), Hodgkin lymphoma (HL), and chronic lymphocytic leukemia (CLL) are associated with an inferior survival. These increases in FLC can be monoclonal (as in myeloma) or polyclonal. The goal was to estimate the frequency of these elevations within distinct types of B-cell and T-cell non-Hodgkin lymphoma (NHL) and whether the FLC measurements are associated with event-free survival (EFS). We studied serum for FLC abnormalities using normal laboratory reference ranges to define an elevated κ or λ FLC. Elevations were further classified as polyclonal or monoclonal. Four hundred ninety-two patients were studied: 453 B-cell and 34 T-cell NHL patients. Twenty-nine % (142/453) of patients had an elevated FLC of which 10% were monoclonal elevations. Within B-cell NHL, FLC abnormalities were most common in lymphoplasmacytic (79%), mantle cell (68%), and lymphomas of mucosa associated lymphoid tissue (31%); they were least common in follicular (15%). The hazard ratio (HR) for EFS in all patients was 1.41 (95% CI; 1.11-1.81); in all B-cell NHL the HR was 1.44 (95% CI 1.11-1.96); in all T-cell NHL the HR was 1.17 (95% CI 0.55-2.49). FLC abnormalities predicted an inferior OS (HR = 2.75, 95% CI: 1.93-3.90, P < 0.0001). The serum FLC assay is useful for prognosis in both B-cell and T-cell types of NHL. In B-cell NHL further discrimination between a monoclonal and polyclonal elevation may be helpful and should be analyzed in prospective clinical trials.

Abstract
BACKGROUND The introduction of rituximab (R) to conventional CHOP chemotherapy for newly diagnosed diffuse large B-cell lymphoma (DLBCL) led to an unequivocal improvement in survival, establishing RCHOP as the standard of care. Still, nearly 40% of DLBCL patients will eventually die of relapsed disease. Efforts to improve outcomes by addition of new biologic agents (X) to the RCHOP backbone are underway. In this era of R(X)CHOP, it is imperative to develop prognostic and predictive markers, not only to identify patients who will suffer a particularly aggressive course, but also to accurately select patients for clinical trials from which they will most benefit. DESIGN The following review was undertaken to describe prognostic factors in DLBCL, with emphasis on markers that are accurate, relatively available, and clinically applicable in 2014. RESULTS The International Prognostic Index retains its validity in the era of RCHOP, although with limited ability to predict those with <50% chance of long-term survival. Gene expression profiling has provided novel insights into the biology of DLBCL and led to the development of immunohistochemistry (IHC) algorithms that are in routine practice. Identification of a 'double-hit' (DH) lymphoma by fluorescent in situ hybridization with aberrations involving MYC and/or BCL2 and BCL6 genes has important implications due to its extremely dismal prognosis with RCHOP. Other markers such as the absolute lymphocyte count (ALC), serum immunoglobulin free light chains, vitamin D levels, serum cytokines/chemokines, and imaging with positron emission tomography (PET) have all shown promise as future predictive/prognostic tests. CONCLUSIONS The future for new treatment options in DLBCL is promising with current clinical trials testing novel targeted agents such as bortezomib, lenalidomide, and ibrutinib as the 'X' in R(X)CHOP. Predictive factors are required to select and randomize patients appropriately for these trials. We envision the day when 'X' will be chosen based on the biological characteristics of the tumor.

Abstract
Hepatitis C virus (HCV) infects B-lymphocytes, provokes cellular dysfunction and causes lymphoproliferative diseases such as cryoglobulinemia and non-Hodgkin's B-cell lymphoma. In the present study, we investigated the serum levels of kappa and lambda free light chains (FLC) of immunoglobulins and the kappa/lambda FLC ratio in Brazilian patients with chronic HCV infection and cryoglobulinemia. We also analyzed the immunochemical composition of the cryoglobulins in these patients. Twenty-eight cryoglobulinemic HCV patients composed the target group, while 37 HCV patients without cryoglobulinemia were included as controls. The median levels of kappa and lambda FLC were higher in patients with cryoglobulinemia compared to controls (p = 0.001 and p = 0.003, respectively), but the kappa/lambda FLC ratio was similar in patients with and without cryoglobulinemia (p > 0.05). The median FLC ratio was higher in HCV patients presenting with advanced fibrosis of the liver compared to HCV patients without fibrosis (p = 0.004). Kappa and lambda FLC levels were strongly correlated with the IgA, IgG and IgM levels in the patients with cryoglobulinemia. In patients without cryoglobulinemia, the kappa FLC level was only correlated with the IgG level, whereas the lambda FLC were weakly correlated with the IgA, IgG and IgM levels. An immunochemical pattern of mixed cryoglobulins (MC), predominantly IgM, IgG, IgA and kappa light chain, was verified in these immune complexes. We concluded that HCV-infected patients presenting cryoglobulinemia have vigorous polyclonal B-lymphocyte activation due to chronic HCV infection and persistent immune stimulation.

While monoclonal immunoglobulins occasionally produced by CLL has previously been implicated in AL amyloidosis, this is the first case of AL amyloidosis resulting from a distinct plasma cell dyscrasia that is not clonally related to the concurrent CLL. Appropriate treatment depended on detailed pathologic diagnosis of both disease processes.

Elevated serum monoclonal and polyclonal free light chains and interferon inducible protein-10 predicts inferior prognosis in untreated diffuse large B-cell lymphoma. Am J Hematol 2014; 89:417-22. [PMID: 24382707 DOI: 10.1002/ajh.23658] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2013] [Revised: 12/24/2013] [Accepted: 12/28/2013] [Indexed: 12/16/2022]
Abstract
The detection of serum free light (FLC) is useful in the diagnosis of several hematological diseases. The role and biological relevance of monoclonal or polyclonal FLC elevations in predicting long-term outcome in diffuse large B-cell lymphoma (DLBCL) is unknown. We determined the relationship of the type of FLC elevations to outcome, tumor genotype, and pattern of serum cytokine elevations in 276 patients with untreated DLBCL. Elevated FLC was an adverse prognostic factor through 6 years of follow-up (monoclonal, Event free survival (EFS) HR = 3.56, 95% CI: 1.88-6.76, P <0.0001; polyclonal, EFS HR = 2.56, 95% CI: 1.50-4.38, P = 0.0006). About 73% of DLBCL tumors with monoclonal FLC elevations were activated B-cell type (ABC) versus 33% from patients with normal FLC. Only ABC-DLBCL lines secreted kappa FLC in vitro and this secretion could be inhibited by the NF-κB inhibitor bortezomib. Patients with monoclonal FLC had significantly (all P <0.001) increased serum levels of IL-12, sIL-2Rα, IL-1R, and IP-10. Patients with polyclonal elevations of FLC had higher levels of IL-6 (P = 0.033), IL-8 (P =0.025), sIL2Rα (P = 0.011), and IL-1R1 (P = 0.041). The combination of elevated FLC and a CXC superfamily chemokine IP-10 predicted a particularly inferior outcome characterized by late relapse. These increased abnormal FLC and cytokines are potentially useful biomarkers for prognosis and selecting agents for untreated DLBCL.

Abstract
A middle-aged male patient presented with fever, polyarthralgia, polyuria, easy fatigability and weight loss for 1 month. Clinically, there was only significant pallor and a swelling over the right sternoclavicular joint. On investigation, there was anaemia, raised urea, creatinine and pus cells in urine with growth of Escherichia coli. There were also hypercalcaemia and osteolytic lesions over the ribs, scapula, clavicle and skull along with distorted renal corticomedullary differentiation. Although the initial diagnosis was likely to be a case of multiple myeloma, serum protein electrophoresis was negative for the monoclonal band and no Bence-Jones protein was detected in urine. Bone marrow plasma cells were less than 10%, but the serum-free light chain assay revealed altered κ:λ ratio. Later in the course of the disease, a cervical lymph node appeared. The biopsy and immunohistochemistry of this lymph node revealed a CD5 positive diffuse large B-cell lymphoma, but unfortunately the patient succumbed to his illness after receiving the first cycle of Rituximab-Cyclophosphamide-Hydroxydoxorubicin-Oncovin-Prednisolone.

Abstract
BACKGROUND SPAPLUS™ is a turbidimetric immunoassay analyzer for detection of excess free light chain (FLC) antigens in serum. Here, we evaluated the analytical performance of Freelite™ Human Kappa Free and Lambda Free on a SPAPLUS™ instrument. METHODS We evaluated the precision, linearity, sample carryover, and drift of the SPAPLUS™ instrument and compared it with Hitachi 7600 and BN™ II instruments. We evaluated the detection of antigen excess for 12 specimens from patients with monoclonal gammopathy. RESULTS The coefficients of variations of κFLC and λFLC were below 5.0%. Linearity was shown in the range of 9.68-152.25 mg/l for κFLC and 4.96-171.09 mg/l for λFLC, and no drift was observed. The κFLC sample carryover was statistically significant, but much smaller than the optimum allowable bias. Agreement rates with the two comparative methods were 87.1, 87.1, and 97.1% or higher for κFLC, λFLC, and the κ/λ ratio, respectively. Antigen excess signals were observed for all 12 antigen excess specimens. CONCLUSIONS The Freelite™ on the SPAPLUS™ exhibited appropriate precision, linearity, and relative comparability to the reagents on the other instruments. It was good at detecting specimens that had previously demonstrated the hook effect due to antigen excess.

Abstract
Immunoglobulin free light chains (FLCs) form part of the middle molecule group of uremic toxins. Accumulation of FLCs has been observed in patients with chronic kidney disease (CKD). The aim of the present study was to measure FLC levels in patients at different CKD stages and to assess putative associations between FLC levels on one hand and biochemical/clinical parameters and mortality on the other. One hundred and forty patients at CKD stages 2-5D were included in the present study. Routine clinical biochemistry assays and assays for FLC kappa (κ) and lambda (λ) and other uremic toxins were performed. Vascular calcification was evaluated using radiological techniques. The enrolled patients were prospectively monitored for mortality. Free light chain κ and λ levels were found to be elevated in CKD patients (especially in those on hemodialysis). Furthermore, FLC κ and λ levels were positively correlated with inflammation, aortic calcification and the levels of various uremic toxins levels. A multivariate linear regression analysis indicated that FLC κ and λ levels were independently associated with CKD stages and β2 microglobulin levels. Elevated FLC κ and λ levels appeared to be associated with mortality. However, this association disappeared after adjustment for a propensity score including age, CKD stage and aortic calcification. In conclusion, our results indicate that FLC κ and λ levels are elevated in CKD patients and are associated with inflammation, vascular calcification and levels of other uremic toxins. The observed link between elevated FLC levels and mortality appears to depend on other well-known factors.

Abstract
New assays for serum immunoglobulin (Ig) free and heavy chain quantification were developed for routine clinical practice. Serum free light chain (sFLC) assay was shown to improve detection, management and prognostication in all plasma cell dyscrasias. More precisely, sFLC measurements proved to be prognostic for the progression of monoclonal gammopathy of undetermined significance and smoldering multiple myeloma (MM), became markers of response and survival in amyloid light-chain amyloidosis and contributed to accurate follow-up of patients with light chain and non secretory MM. In addition, sFLC and they ratio (sFLCR) were shown useful for the prognosis and monitoring of intact Ig myeloma; their evaluation was incorporated in the new uniform response criteria. sFLC or sFLCR were also observed abnormal in B-cell non-Hodgkin lymphoma/chronic lymphocytic leukemia (CLL). Moreover, increased sFLC levels, summated sFLC or abnormal sFLCR predict shorter overall survival in early-stage CLL while increased sFLC constituted an independent, adverse prognostic factor for event-free and overall survival in diffuse large B-cell lymphoma and Waldenstrom’s macroglobulinemia. Clinical applications of heavy Ig chain separately (HLC) measurements are more recent and mainly concern MM in which HLC deriving ratios correlated with parameters of disease activity and constituted an adverse survival marker.

Abstract
To clarify the presentation and course of patients with chronic lymphocytic leukemia (CLL) and amyloidosis. Mayo databases were interrogated for patients who carried a diagnosis of amyloidosis and CLL evaluated at Mayo Clinic, Rochester from January 1974 to October 2012. Charts were abstracted and data analyzed. Of the 33 patients identified, 20 (61%) were diagnosed with AL and 13 (39%) with non-AL. Only four patients had immunoglobulin light chain amyloidosis (AL) that could be solely attributed to the CLL clone; another six had both a plasma cell clone and a CLL clone that shared the same light chain. Median overall survival was 15.6 months for patients with AL and 58.1 months for patients with non-AL. For patients with AL management involved chemotherapy targeted toward monoclonal plasma cells, lymphocytes or both, and for patients with non-AL no specific amyloid treatment was administered. AL is a rare complication of CLL, but in this elderly population of patients non-AL is nearly as common. Distinguishing between these two groups is essential since patients with non-AL amyloidosis have better outcomes and they do not require cytotoxic chemotherapy to treat their amyloidosis.

Abstract
Elevated serum free light chains (FLCs) have been associated with an unfavorable prognosis in diffuse large B-cell lymphoma (DLBCL). The aim of this study was to determine the clinical relevance of a quantitative assessment of intact circulating immunoglobulin (Ig), using serum Ig heavy chain/light chain pair (HLC) measurements in patients with DLBCL. FLC and HLC were measured in 409 serum samples of patients with DLBCL included in the LNH03-B clinical trial program of the Groupe d'Etudes des Lymphomes de l'Adulte (GELA). Patients with an abnormal IgMκ/IgMλ ratio or an abnormal FLC ratio more frequently displayed adverse clinical characteristics. Patients with abnormal IgMκ/IgMλ ratios had inferior progression-free survival (PFS) and overall survival (OS) as compared to patients with a normal ratio in the overall cohort (5-year PFS 44.9% vs. 69.3%, p = 0.0003 and 5-year OS 50.8% vs. 78.1%, p = 0.0003) and in the R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone) cohort (5-year OS 43.5% vs. 70.3%, p = 0.003). In multivariate analysis, including elevated FLC/HLC and International Prognostic Index (IPI), an abnormal IgMκ/IgMλ ratio (hazard ratio [HR] = 1.54, 95% confidence interval [CI] 1.03-2.3, p = 0.03) remained predictive of shorter progression-free survival. Gene expression profile experiments and immunohistochemistry indicate that this measurement is at least partially related to tumor cell secretion. Both elevated serum FLCs and an abnormal IgMκ/IgMλ ratio are associated with unfavorable outcomes in patients with DLBCL treated by R-CHOP.

Abstract
The ascertainment of serum free light chain (sFLC) levels has been shown to be valuable in screening for the presence of plasma cell dyscrasia as well as for baseline prognosis in newly diagnosed patients. For patients with amyloidosis and those with oligo-secretory or non-secretory multiple myeloma (MM), serial measurement of sFLC has also been shown to be valuable in monitoring disease status. However, in patients with a measureable, intact monoclonal protein by immunofixation (M protein), the serial measurement of sFLC remains undefined and is currently not recommended in professional guidelines. Herein, we provide data comparing sFLC with M protein as biomarkers of response in newly diagnosed patients with MM undergoing induction therapy with the novel agents thalidomide, lenalidomide and/or bortezomib. We show that although M protein appears to outperform sFLC comparatively over the course of induction therapy, the addition of FLC to M protein further informs the characterization of residual disease status post-induction. Moreover, sFLC at the time of stem cell mobilization appears to hold prognostic power for survival endpoints following high-dose chemotherapy/autologous stem cell transplant (HDC/SCT). These findings suggest potentially novel roles for sFLC in patients with MM with an intact M protein receiving novel agent-based induction strategies followed by HDC/SCT.

Abstract
Serum free light chain (sFLC) assays were shown to improve detection, management, and prognostication in plasma cell disorders. Recently, sFLC assays improved detection of M proteins when combined with standard methods of protein electrophoresis/immunofixation in patients with non-Hodgkin lymphoma/chronic lymphocytic leukemia (NHL/CLL). Incidence of abnormal sFLC ratio (sFLCr) varied from 0% to 36% and 29.7% to 59% in NHL and CLL, respectively. Increased sFLC levels or abnormal sFLCr predict shorter overall survival in early-stage CLL. Furthermore, abnormal sFLCr correlated with advanced disease stage and poorer outcome. In diffuse large B-cell lymphomas, increased sFLC was demonstrated as an independent, adverse prognostic factor for overall/event-free survival. Moreover, abnormal sFLCr can be a diagnostic tool in central nervous system lymphomas. Finally, the quantitative FLC assay has the potential to become a new, easily measured biomarker for predicting prognosis and enhanced detection in NHL/CLL. It may be used serially at follow-up evaluations to provide clues to relapse.

Abstract
The serum free light chain (FLC) assay quantitates free immunoglobulin kappa and lambda light chains, which has prognostic value in plasma cell dyscrasias. However, there is limited data on serum FLC in lymphoid malignancies. We analyzed the association of pretreatment FLC with event-free survival (EFS) and overall survival (OS) in 100 patients with Hodgkin lymphoma (HL). Elevated polyclonal FLC were present in 30% of patients; these patients had an inferior EFS (HR = 4.84; 95% CI: 1.84-12.7) and OS (HR = 8.87; 95% CI: 2.35-33.52) compared to patients with normal FLC. Further studies of FLC in HL are warranted.

Abstract
Elevated serum CD44, intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1) have been linked to poor prognosis in aggressive lymphomas, but their utility in low grade lymphomas remains undefined. We evaluated serum CD44, VCAM-1 and ICAM-1 levels in 100 patients with newly diagnosed indolent NHL. The median pre-treatment values of the markers were as follows: CD44 540 ng/mL (range 156-1201), ICAM-1 311 ng/mL (range 102-1222) and VCAM-1 1165 ng/mL (range 248-4779). On univariate analysis, elevated sCD44, sICAM-1 and sVCAM-1 were significantly associated with worse overall (OS) and progression-free survival (PFS). In a subset analysis of patients with stage IV disease, the effects of sCD44 and sICAM-1 on OS persisted (p<0.05), as did the effect of sCD44 on PFS (p<0.01). In a multivariate analysis that included conventional prognostic factors and the Follicular Lymphoma International Prognostic Index (FLIPI) model, sICAM-1 demonstrated prognostic value for OS and PFS. We conclude that serum CD44, ICAM-1 and VCAM-1 can potentially be prognostic in patients with indolent NHL. Though the FLIPI model remains the gold standard for prognosis, these quantitative serologic markers may be useful as adjunct tools in assessing disease risk.

Abstract
Free light chains (FLCs) are the most commonly detected paraproteins in chronic lymphocytic leukemia (CLL). We examined the types of FLC abnormalities and prognostic utility of the FLC assay compared with standard prognostic biomarkers in a prospective cohort of 339 patients with newly diagnosed CLL. Three types of FLC abnormalities were identified: monoclonal elevated FLC (elevated κ and/or λ with abnormal FLC ratio), polyclonal elevated FLC (elevated κ and/or λ with normal FLC ratio), and ratio-only FLC abnormality (normal range κ and λ with abnormal FLC ratio). One hundred sixty-five patients (49%) had a FLC abnormality with approximately equal distribution among monoclonal elevation, polyclonal elevation, and ratio-only abnormality. All FLC abnormalities were associated with poor time to first treatment: monoclonal FLC (hazard ratio [HR], 4.99; 95% confidence interval [CI], 2.94-8.48), polyclonal FLC (HR, 2.40; 95% CI, 1.24-4.64), ratio-only FLC (HR, 2.57; 95% CI, 1.40-4.69). Monoclonal FLC and polyclonal FLC were associated with poor overall survival compared with patients with normal FLC. Results remained significant after adjusting for Rai stage. The FLC assay is a simple, widely available clinical test with similar prognostic utility as routinely used prognostic biomarkers for CLL. Among persons with FLC abnormalities, the type of abnormality affects prognostic significance.

Abstract
HIV infection is associated with a much higher risk for the development of non-Hodgkin lymphoma (AIDS-NHL). The principal causes of lymphomagenesis in HIV-infected individuals are thought to be the loss of immune function seen in HIV infection, which results in the loss of immunoregulation of Epstein-Barr virus-infected B cells, as well as HIV infection-associated immune dysregulation, including chronic B-cell activation. In this review, we discuss recent reports that further support the importance of these factors, and we highlight emerging evidence of different mechanisms that potentially drive lymphomagenesis in HIV-infected individuals.

Abstract
PURPOSE The serum free light chain (FLC) assay quantitates free kappa (κ) and free lambda (λ) immunoglobulin light chains. This assay has prognostic value in plasma cell proliferative disorders. There are limited data on serum FLC in B-cell malignancies. PATIENTS AND METHODS The association of pretreatment FLC with event-free survival (EFS) and overall survival (OS) in diffuse large B-cell lymphoma (DLBCL) was evaluated in 76 patients from the North Central Cancer Treatment Group trial N0489 (NCT00301821) and 219 patients from the University of Iowa/Mayo Clinic Specialized Program of Research Excellence Molecular Epidemiology Resource (MER). Published reference ranges were used to define an elevated FLC or an abnormal κ:λ FLC ratio. RESULTS Elevated FLC or abnormal κ:λ FLC ratio was present in 32% and 14% of patients, respectively. Patients with elevated FLC had an inferior OS and EFS in both cohorts compared with patients with normal FLC (N0489: EFS hazard ratio [HR], 3.06; OS HR, 3.16; both P < .02; MER: EFS HR, 2.42; OS HR, 3.40; both P < .001; combined EFS HR, 2.57; OS HR, 3.74; both P < .001). All associations remained significant for EFS and OS after adjusting for the International Prognostic Index (IPI). Abnormal κ:λ FLC ratio was modestly associated with outcome in the combined group (EFS HR, 1.61; OS HR, 1.67; both P = .07), but not in patients without corresponding elevated κ or λ. Elevated FLC was the strongest predictor of outcome in multivariable models with the IPI components. CONCLUSION Increased serum FLC is an independent, adverse prognostic factor for EFS and OS in DLBCL and warrants further evaluation as a biomarker in DLBCL.

Abstract
AbstractHigh serum concentrations of monoclonal free light chain (FLC) kappa or lambda are markers of plasma cell dyscrasia.We developed new, latex-enhanced, specific nephelometric assays based on monoclonal antibodies for the determination of FLC kappa and lambda in serum, EDTA plasma and Li-heparin plasma for use on the Siemens BN™ systems.Reference ranges were determined from 369 samples: FLC kappa 6.7–22.4 mg/L, FLC lambda 8.3–27.0 mg/L and kappa/lambda ratio 0.31–1.56. Protection from falsely low results due to antigen excess is obtained with a built-in pre-reaction in the assay protocols. Lot-to-lot consistency between three different lots of reagent, calibrators and supplementary reagent lots showed normalized differences <7.5%. The reproducibility of serum samples varied between 4% and 7%. The method comparison with Freelite™ assays showed normalized differences of 19.7%, 32.7% and 21.7%, respectively, for FLC kappa, lambda and ratio, correlations of 0.94, 0.77 and 0.73, and concordance rates of 99.2%, 94.2% and 95%.N Latex FLC demonstrates high precision, good lot-to-lot consistency and freedom from a high-dose hook effect. The method comparison between Freelite™ and the N Latex FLC assays showed good clinical concordance. Further studies need to reveal the clinical value of the new FLC assays.

Abstract
In a variety of hematologic malignancies, immunoglobulin light chains (LC) are overproduced clonally and circulate without being linked by disulphide bonds to the immunoglobulin heavy chain. The recent development of a robust assay known as κ and λ "free" LC (FLC) to quantify the levels of these unbound LC in the serum, and thereby determine their ratio, has led to an explosion of studies that demonstrate its utility in a wide range of hematologic disorders. This article summarizes laboratory testing for serum FLC, with a particular focus on clinical applications for the test.

Abstract
OBJECTIVES Chronic lymphocytic leukemia (CLL) is characterized by a highly variable clinical course. This retrospective study is planned to assess the prognostic value of serum free light chain (sFLC) levels and FLC ratio (FLCR) in CLL. METHODS Quantitative levels of sFLC were measured nephelometrically in sera collected at diagnosis. The expressions of ZAP70 and CD38 were quantified by flow cytometry. Chromosomal abnormalities were determined by interphase fluorescence in situ hybridization (FISH). RESULTS In a cohort of 101 patients with a median follow-up of 29 (1-234) months, sFLC levels were found to be high in 55 patients (54.5%). An abnormal FLCR was found in 30 patients (29.7%). FISH-based genetic risk groups did not differ significantly with respect to sFLC and FLCR (P > 0.05). Median time to first treatment was shorter in patients with high sFLC levels (P = 0.02). Median overall survival (OS) was shorter in patients with high sFLC levels (P = 0.01) and abnormal FLCR (P = 0.05). In patients with early stage disease, median OS was shorter in high sFLC (P = 0.03) and abnormal FLCR groups (P = 0.048). A relationship was observed between abnormal sFLC levels and CD38 positivity on logistic regression analysis (P = 0.003; OR: 4.44; 95% CI: 1.66-11.8). CONCLUSIONS This study highlighted the adverse prognostic impact of high sFLC levels and abnormal FLCR with regard to survival in CLL, even in early stage patients. Prospective studies are warranted to validate the adverse impact of sFLC and FLCR on clinical outcome.

Abstract
BACKGROUND Detection of plasma cell dyscrasias (PCD) requires screening of serum and urine for monoclonal proteins. Several studies have demonstrated increased sensitivity and specificity when measurement of serum free light chain (SFLC) is part of the screening protocol. In addition, omission of immunofixation (IFE) in the standard work-up that includes SFLC assay has been proposed. This study attempts to define the role of the SFLC assay in a screening strategy limited to serum only. It compares outcomes to a serum-only screening strategy that omits serum IFE. METHODS Serum from 691 patients was analysed for the presence of monoclonal protein using standard serum IFE, serum protein electrophoresis (SPE) and measurement of SFLC. Data were analysed retrospectively. RESULTS Specificity and sensitivity of abnormal SFLC-ratios for the detection of monoclonal protein using IFE were 96% and 41%, respectively. Eighteen patients with negative monospecific and Bence Jones IFE, but abnormal SFLC-ratios were identified. In most cases, this could be attributed to kidney and inflammatory disease or haematological disorders. In four cases, this resulted in further diagnostic investigation and light chain disease was later detected in two cases. Light chain disease was confirmed in one case but not confirmed in the other patient. In 14 patients, Bence Jones IFE was negative, although the concentrations of SFLC suggested the presence of monoclonal Bence Jones protein at concentrations detectable by IFE. Thus, either the anti-serum failed at detection, there was polymerisation of the free light chains or the SFLC assay overestimated protein concentrations. Simulating a work-up that included IFE only if abnormalities were detected by SPE or the SFLC assay would have resulted in 26% fewer IFEs being performed, but three patients with monoclonal proteins by IFE would have been missed. CONCLUSIONS Abnormal SFLC concentrations are neither sensitive nor specific for the detection of monoclonal proteins by IFE. Not all PCD are accompanied by excessive production of SFLC, and several other conditions, such as renal disease are associated with increased SFLC concentrations. An abnormal SFLC-ratio is a specific marker for PCD, and occurs primarily in patients with haematological disease. If renal and inflammatory diseases are excluded, this should prompt further diagnostic investigation. Screening of serum without performing an IFE as a standard procedure leads to a reduction of sensitivity when compared to screening of serum that includes IFE.

Abstract
BACKGROUND Protein and immunofixation electrophoresis of serum and urine are established as diagnostic aids for identifying monoclonal gammopathies. However, many patient sera sent to laboratories are not accompanied by urine samples and recent reports suggest the use of serum free light chain (sFLC) analysis in combination with serum protein electrophoresis (SPE) and immunofixation electrophoresis (lFE) could eliminate the need for urinalysis. The aim of the study was to assess the utility of sFLC measurement in addition to serum protein electrophoresis in the identification of patients with B-cell malignancies. METHODS A total of 952 serum samples were analysed by serum protein electrophoresis and those with abnormal bands were analysed by immunofixation. sFLCs were measured in a retrospective manner by automated assay. RESULTS In our study of 952 patient sera, it was found that FLC analysis identified 23 additional cases of B-cell malignancies which were missed by SPE. CONCLUSIONS The additional malignancies identified by sFLC analysis add support for its inclusion in the routine screening protocol for B-cell malignancies.

Abstract
BACKGROUND Currently, monoclonal immunoglobulins are identified and quantified from bands on electrophoretic gels. As an alternative, clonality might be determined by measuring the separate light chain types of each Ig class to allow numerical assessment of Ig'kappa/Ig'lambda ratios, analogous to free light chain kappa/lambda ratios. METHODS Using immunization, tolerization, and adsorption procedures, we prepared sheep antibodies against each of the 6 separate molecules, IgGkappa, IgGlambda, IgAkappa, IgAlambda, IgMkappa, and IgMlambda. Antibody targets comprised the junctional epitopes between the heavy chain and light chain domains. After purification, we assessed the antisera on a Siemens Dade-Behring BN II nephelometer for analytical quality and clinical utility. RESULTS High-avidity, specific antibodies allowed the production of automated nephelometric immunoassays for each Ig light chain type. Laboratory comparison with serum protein electrophoresis, using dilution experiments, showed lower analytical sensitivity for monoclonal IgG detection but similar or greater sensitivity for IgA and IgM, particularly when the monoclonal bands overlaid transferrin. Results obtained from typing of monoclonal proteins into IgG, A, or M types were comparable with results obtained by immunofixation-electrophoresis methods. Initial clinical studies, in multiple myeloma patients, indicated that Ig'kappa/Ig'lambda ratios were sometimes more sensitive than immunofixation electrophoresis, provided numerical results, and correlated with changes in disease. CONCLUSIONS Immunoassays for intact Ig kappa/lambda pairs are possible and should assist in the management of patients with monoclonal gammopathies.

Abstract
The measurement of immunoglobulin serum free light chains (sFLC) has prognostic significance in plasma cell dyscrasias but its role in chronic lymphocytic leukaemia (CLL) is unknown. This retrospective study from three UK hospitals analysed sFLC in 181 untreated/pre-treatment CLL patients and 78 treated CLL patients, with samples taken later in their disease. An abnormal sFLC ratio was significantly associated with poor overall survival for the 181 untreated/pre-treatment patients (P = 0.0001) and for all patients (P = 0.002), irrespective of cause of death. Using multivariate analysis (n = 194), four independent prognostic variables for overall survival were identified namely Zap-70 (P = 0.0001), beta2M (P = 0.01), IGHV mutation status (P = 0.017) and an abnormal sFLC ratio (P = 0.024). For CLL patients with unmutated IGHV genes, elevated kappa/lambda ratios were adversely prognostic. For patients with mutated IGHV genes, reduced kappa/lambda ratios were adversely prognostic and associated with the poor prognostic IGHV3-21, IGHV3-48 and IGHV3-53 subgroups, suggesting an abnormal sFLC ratio may reflect biological subgroups within CLL. Abnormal sFLC ratios need to be studied prospectively in CLL patients and the biological rationale for their abnormality investigated.

Abstract
BACKGROUND Serum free light chain (SFLC) measurements have recently come into use as an aid for diagnosing monoclonal gammopathy. We evaluated SFLC measurements in combination with serum protein electrophoresis (SPE) and clinical information for diagnosing multiple myeloma (MM) in a hospital population. METHODS We measured SFLCs in 3818 sera received for SPE over a 1-year period when patient symptoms or biochemical findings suggested myeloma-related tissue damage (n = 1067). We reviewed SPE and SFLC results from 489 patients together with their final diagnoses obtained from the hospital information technology department. RESULTS SFLC measurement, combined with SPE and clinical information, allowed identification of 95% of patients (38 of 40) with previously undiagnosed MM, macroglobulinemia, or primary amyloidosis. Additionally, we identified 45 patients with monoclonal gammopathy of undetermined significance (MGUS) and 4 with plasmacytoma. Of patients followed at our hospital in whom SFLCs were not measured, only 1 patient was diagnosed with MM. This patient had anemia and was mistakenly not tested for SFLCs. An abnormal kappa/lambda ratio was found in 26 of 29 patients with MM but also in 36 of 203 patients with renal impairment, polyclonal immunoresponse, or other nonhematological diagnoses. None of the 203 patients with nonhematological disease had a kappa/lambda ratio <0.05 or >10. CONCLUSIONS The combined use of SPE, SFLC measurements, and clinical criteria allows MM to be efficiently diagnosed or excluded based on serum measurements only.

Abstract
The Importance of Free Light Chains of Immunoglobulins Determination in SerumFor many years, Bence Jones proteinuria has been an important diagnostic marker for multiple myeloma. Relatively new serum tests for free kappa and free lambda light chains of immunoglobulins reflect the production of free light chains more accurately than urine tests. In this study, we examined the value of serum free light chains measurement in the diagnosis of some neoplastic diseases and the discrepance between the findings of serum protein electrophoresis and serum free light chains. Thirty one patients (f=19, m=12) were included in the study, most of them with blood malignant diseases. The results show that in six patients with normal gamma and beta electrophoresis fractions there are abnormal levels of free light chains and/or an abnormal κ/LD ratio. In 20 patients we found an abnormal κ/LD ratio, and in 21 patients we found an abnormal κ or LD level, or both. The obtained results show the important role of serum free light chains determination in identifying patients with monoclonal gammopathies.
