Serum Free Light Chains Removal by HFR Hemodiafiltration in Patients with Multiple Myeloma and Acute Kidney Injury. a Case Series

Background/Aims: Multiple myeloma (MM) represents 10% of all haematologic malignancies. Renal involvement occurs in 50% of MM patients; of them, 12-20% have acute kidney injury (AKI), with 10% needing dialysis at presentation. While hemodialysis (HD) has no effect upon circulating and tissue levels of monoclonal proteins, novel apheretic techniques aim at removing the paraproteins responsible for glomerular / tubular deposition disease. High cut-off HD (HCO-HD) combined with chemotherapy affords a sustained reduction of serum free light chains (FLC) levels. One alternative technology is haemodiafiltration with ultrafiltrate regeneration by adsorption on resin (HFR–SUPRA), employing a “super high-flux” membrane (polyphenylene S-HF, with a nominal cut-off of 42 kD). Aim of our pilot study was to analyze the effectiveness of HFR-SUPRA in reducing the burden of FLC, while minimizing albumin loss and hastening recovery of renal function in 6 subjects with MM complicated by AKI. Methods: Six HD-dependent patients with MM were treated with 5 consecutive sessions of HFR-SUPRA on a Bellco® monitor, while simultaneously initiating chemotherapy. Levels of albumin and FLC were assessed, calculating the rates of reduction. Renal outcome, HD withdrawal and clinical follow-up or death were recorded. Results: All patients showed a significant reduction of FLC, whereas serum albumin concentration remained unchanged. In three, HD was withdrawn, switching to a chemotherapy alone regimen. The other patients remained HD-dependent and died shortly thereafter for cardiovascular complications. Conclusion: Our study suggests that HFR-SUPRA provides a rapid and effective reduction in serum FLC in patients with MM and AKI

Publisher Copyright: © 2018 The AuthorsMultiple myeloma (MM) remains an incurable disease, with little information available on its management in real-world clinical practice. The results of the present prospective, noninterventional observational study revealed great diversity in the treatment regimens used to treat MM. Our results also provide data to inform health economic, pharmacoepidemiologic, and outcomes research, providing a framework for the design of protocols to improve the outcomes of patients with MM. Background: The present prospective, multinational, noninterventional study aimed to document and describe real-world treatment regimens and disease progression in multiple myeloma (MM) patients. Patients and Methods: Adult patients initiating any new MM therapy from October 2010 to October 2012 were eligible. A multistage patient/site recruitment model was applied to minimize the selection bias; enrollment was stratified by country, region, and practice type. The patient medical and disease features, treatment history, and remission status were recorded at baseline, and prospective data on treatment, efficacy, and safety were collected electronically every 3 months. Results: A total of 2358 patients were enrolled. Of these patients, 775 and 1583 did and did not undergo stem cell transplantation (SCT) at any time during treatment, respectively. Of the patients in the SCT and non-SCT groups, 49%, 21%, 14%, and 15% and 57%, 20%, 12% and 10% were enrolled at treatment line 1, 2, 3, and ≥ 4, respectively. In the SCT and non-SCT groups, 45% and 54% of the patients had received bortezomib-based therapy without thalidomide/lenalidomide, 12% and 18% had received thalidomide/lenalidomide-based therapy without bortezomib, and 30% and 4% had received bortezomib plus thalidomide/lenalidomide-based therapy as frontline treatment, respectively. The corresponding proportions of SCT and non-SCT patients in lines 2, 3, and ≥ 4 were 45% and 37%, 30% and 37%, and 12% and 3%, 33% and 27%, 35% and 32%, and 8% and 2%, and 27% and 27%, 27% and 23%, and 6% and 4%, respectively. In the SCT and non-SCT patients, the overall response rate was 86% to 97% and 64% to 85% in line 1, 74% to 78% and 59% to 68% in line 2, 55% to 83% and 48% to 60% in line 3, and 49% to 65% and 36% and 45% in line 4, respectively, for regimens that included bortezomib and/or thalidomide/lenalidomide. Conclusion: The results of our prospective study have revealed great diversity in the treatment regimens used to manage MM in real-life practice. This diversity was linked to factors such as novel agent accessibility and evolving treatment recommendations. Our results provide insight into associated clinical benefits.publishersversionPeer reviewe

Low absolute lymphocyte count is a poor prognostic factor in diffuse-large-B-cell-lymphoma

The prognostic value of absolute lymphocytic count (ALC), has been a recent matter of debate in non-Hodgkin-lymphoma (NHL). We assessed prospectively the value of ALC at diagnosis and also after the completion of immuno-chemotherapy in 101 diffuse-large-B-cell-lymphoma (DLBCL). Analysis of prognostic factors with respect to overall survival (OS), event free survival (EFS) and progression free survival (PFS) was done by two-tailed log-rank test. The ALC cut-off value was calculated as < 0.84 x 10(9)/L at diagnosis: this was a strong negative prognostic factor for OS (p = 0.0004), EFS (p < 0.00001) and PFS (p < 0.00001) and in multivariate analysis was independent from the revised-international-prognostic-index (R-IPI). ALC after chemo-immunotherapy was not of prognostic value. As R-IPI and ALC < 0.84 x 10(9)/L, were the factors better discriminating poor prognosis, a new trichotomous score (ALC/R-IPI) was built up: (1) low risk: R-IPI = very good or good and ALC < 0.84 x 10(9)/L; (2) intermediate risk: patients with at least one risk factor (R-IPI = poor or ALC < 0.84 x 10(9)/L). (3) high risk: patients with both risk factors. This new prognostic score was highly significant in univariate analysis for OS (p = 0.0002), EFS (p < 0.00001) and PFS (p < 0.00001). In multivariate analysis ALC/R-IPI was the most predictive factor for OS (OR = 2.954; p = 0.002) and EFS (OR = 2.381; p < 0.00001) and the only predictive factor for PFS (OR = 4.018; p < 0.00001). Our data, show that ALC at diagnosis has a strong prognostic relevance and is independent from the R-IPI. The new score including both values proved the most powerful predictor at multivariate analysis

Challenges in Diagnosis and Clinical Management of COVID-19 in Patient with B-Cell Chronic Lymphocytic Leukemia (CLL): Report of One Case

We report here a case of a patient affected by B-cell chronic lymphocytic leukemia (CLL) that developed COVID-19 during the actual SARS-CoV-2 outbreak. The coexistence of CLL and COVID-19 raises many questions regarding the possible increased risk of developing COVID-19 among patients with CLL, the problems in managing therapies for both diseases and, above all, the difficulties in diagnosing COVID-19 in patients affected by CLL. In our patient, an 84-year-old man, the recognition of COVID-19 was delayed because of its atypical clinical presentation and technical problems related to the methods used for the diagnosis. Based on the symptoms and the radiological aspect of the lung, the occurrence of COVID-19 was suspected. Repeated tests on oro/nasopharyngeal swabs gave negative results, causing a delay in the diagnosis. Moreover, different methods used to identify the SARS-CoV-2 antibodies in serum gave conflicting results, and only two tests were able to identify SARS-CoV-2 Abs of the IgG type. During the clinical course of unrecognized COVID-19, our patient developed severe complications and did not receive any specific treatment for the two diseases. Recognition of COVID-19 in patients with CLL is a challenging task and the most accurate methods are necessary to overcome the diagnostic difficulties encountered
