SARS-CoV-2 infection-related deregulation of blood lipids in a patient with -/-LDLR familial homozygous hypercholesterolemia: A case report.

Background: The effect of SARS-CoV-2 infection in blood lipids of homozygous familial hypercholesterolemia (HoFH) has not been explored.

Case Summary: We report a case of a 43-year-old male patient with -/-LDLR HoFH with previous history of premature coronary artery disease, coronary artery bypass graft (CABG) and surgical repair of aortic valve stenosis. He presented with an abrupt decrease of his blood lipid levels during acute infection with SARS-CoV2 and subsequently a rebound increase above pre-infection levels, refractory to treatment including LDL-apheresis, statin, ezetimibe and lomitapide up-titration to maximum tolerated doses.

Immune Checkpoint Inhibitors' Associated Renal Toxicity: A Series of 12 Cases.

We present a series of twelve patients, bearing a wide range of solid malignancies, who received either PD-L1 or a combination of PD-L1 and CTLA-4 inhibitors. Following immunotherapy administration, they exhibited the clinical signs indicative of renal toxicity, including increased serum creatinine levels, proteinuria, nephrotic syndrome and/or hematuria. All patients underwent renal biopsy.

Consolidation with a short course of daratumumab in patients with AL amyloidosis or light chain deposition disease.

Daratumumab has major and rapid activity in AL amyloidosis with favourable toxicity. We used as a consolidation a short course of daratumumab in 25 patients with AL amyloidosis or light chain deposition disease (LCDD), who had not achieved a haematologic complete response (hemCR) after standard therapy with bortezomib, cyclophosphamide and dexamethasone (VCD). We evaluated minimal residual disease (MRD) and changes in the bone marrow (BM) microenvironment before and after consolidation using next generation flow cytometry (NGF).

Clinico-radiologic features and therapeutic strategies in tumefactive demyelination: a retrospective analysis of 50 consecutive cases.

Aims: Our goal was to expand the spectrum of clinico-radiologic characteristics and the possible therapeutic choices in patients with tumefactive demyelinating lesions (TDLs).

Methods: A retrospective analysis of 50 patients with at least one TDL was performed at an academic neurology center (2008-2020).

Results: Our cohort comprised mostly women (33/50) with a mean age of 38 years at TDL onset.

Carfilzomib-associated renal toxicity is common and unpredictable: a comprehensive analysis of 114 multiple myeloma patients.

Carfilzomib (CFZ) is a non-reversible proteasome inhibitor approved for the treatment of patients with relapsed and refractory myeloma (RRMM). Its use has been associated with cardiovascular toxicity but although recently a signal of clinically significant renal complications has also been identified, it is less extensively investigated. We analyzed data of 114 consecutive patients with RRMM who received CFZ-based regimens.

Circulating Soluble Urokinase-Type Plasminogen Activator Receptor Levels Reflect Renal Function in Newly Diagnosed Patients with Multiple Myeloma Treated with Bortezomib-Based Induction.

(1) Background: Soluble urokinase-type plasminogen activator receptor (suPAR) has been implicated in the pathogenesis of kidney disease in different disease settings. The aim of this study was to investigate a possible link between suPAR circulating levels and renal impairment (RI) in newly diagnosed patients with symptomatic multiple myeloma (NDMM) before and after frontline therapy with bortezomib-based regimens. (2) Methods: We studied 47 NDMM patients (57% males, median age 69.

AChR-and MuSK-positive myasthenia gravis: Double trouble.

This is a report of an early onset AChR-and MuSK-positive myasthenia gravis. The double seropositivity was detected at the onset of the disease and persisted during 3.5 years follow-up despite the chronic immunotherapy and thymectomy.

Daratumumab-based therapy for patients with monoclonal gammopathy of renal significance.

Treatment of the plasma cell clone in monoclonal gammopathy of renal significance (MGRS) is necessary in order to reduce toxic immunoglobulin load to the kidneys and salvage renal function. There are limited data on the use of daratumumab in patients with MGRS. We summarize our experience with the use of daratumumab-based therapy in 25 MGRS patients, 12 of whom were previously untreated.

Timing and impact of a deep response in the outcome of patients with systemic light chain (AL) amyloidosis.

A rapid and deep haematologic response is fundamental in order to improve outcomes of patients with AL amyloidosis. We evaluated the impact of timing and depth of haematologic response at early time points (at 1 and 3 months from the start of therapy) in 227 consecutive previously untreated AL patients, who received bortezomib-based primary therapy. After 1 month of therapy, 30.

Primary treatment of light-chain amyloidosis with bortezomib, lenalidomide, and dexamethasone.

Bortezomib and dexamethasone with cyclophosphamide (CyBorD) or melphalan (BMDex) are commonly used primary treatments for light-chain (AL) amyloidosis, but limited data exist on bortezomib with immunomodulatory drug combinations. We report our experience with primary therapy with a bortezomib, lenalidomide, and dexamethasone (VRD) "light" regimen in 34 consecutive patients with AL amyloidosis. The majority (79%) had cardiac involvement, 15% and 23% were Mayo stage 3A and 3B, respectively, and 54% had renal involvement.

Efficacy of lenalidomide as salvage therapy for patients with AL amyloidosis.

We retrospectively evaluated 55 consecutive patients who received at least one dose of lenalidomide for relapsed/refractory AL amyloidosis. Their median age was 63 years; 72% had heart and 75% kidney involvement and 13% were on dialysis; while 20%, 46% and 34% had Mayo stage -1, -2 and -3 disease, respectively. Median time from start of primary therapy to lenalidomide was 15 months (range 2-100) and median number of prior therapies was 1 (range 1-4); 73% of the patients had prior bortezomib and 42% were bortezomib-refractory.

Growth differentiation factor-15 is a new biomarker for survival and renal outcomes in light chain amyloidosis.

Growth differentiation factor-15 (GDF-15) improves prognostication in patients with cardiovascular disorders in addition to conventional cardiac markers (N-terminal pro B-type natriuretic peptide [NT-proBNP], troponins [Tns]) and has shown prognostic value in patients with renal diseases. In patients with light chain (AL) amyloidosis, cardiac involvement is the major determinant of prognosis, and cardiac markers define prognosis, whereas biomarkers of renal involvement stratify renal risk. We explored the prognostic importance of serum level of GDF-15 in patients with AL amyloidosis in 2 independent cohorts.

Cardiac and renal complications of carfilzomib in patients with multiple myeloma.

Clinical trials with carfilzomib have indicated a low but reproducible incidence of cardiovascular and renal toxicities. Among 60 consecutive myeloma patients treated with carfilzomib-based regimens who were thoroughly evaluated for cardiovascular risk factors, 12% (95% confidence interval, 3.8%-20%) experienced a reversible reduction of left ventricular ejection fraction (LVEF) by ≥20%, an objective measure of cardiac dysfunction.

Renal outcomes in patients with AL amyloidosis: Prognostic factors, renal response and the impact of therapy.

A staging system for patients with renal AL amyloidosis, based on eGFR (<50 ml/min/1.73 m ) and proteinuria (≥5 g/day) at diagnosis, as well as criteria for renal progression (≥25% eGFR reduction) and response (≥30% reduction of proteinuria without renal progression) were recently proposed. We validated these criteria in a cohort of 125 patients with renal AL amyloidosis, mostly treated with bortezomib or lenalidomide.

Hematologic and renal improvement of monoclonal immunoglobulin deposition disease after treatment with bortezomib-based regimens.

Monoclonal immunoglobulin deposition disease (MIDD) is characterized by non-organized immunoglobulin-fragments along renal basement membranes with subsequent organ deterioration. Treatment is directed against the immunoglobulin-producing clone. We treated 18 MIDD patients with bortezomib-based regimens (12 received bortezomib-dexamethasone, 6 bortezomib-dexamethasone with cyclophosphamide).

Clinical and prognostic significance of serum levels of von Willebrand factor and ADAMTS-13 antigens in AL amyloidosis.

Cardiac dysfunction determines prognosis in amyloid light-chain (AL) amyloidosis. The heart is the central organ of the vascular system in which endothelium function is critical for the circulatory homeostasis, but there are limited data on endothelial function in AL amyloidosis. von Willebrand factor (VWF) has been considered as a marker of endothelial activation and dysfunction, whereas a disintegrin and metalloproteinase with thrombospondin type-1 repeats 13 (ADAMTS-13) cleaves VWF multimers, but both have been associated with prognosis in cardiovascular disease.

Bortezomib-based triplets are associated with a high probability of dialysis independence and rapid renal recovery in newly diagnosed myeloma patients with severe renal failure or those requiring dialysis.

Renal failure (RF) is a common and severe complication of symptomatic myeloma, associated with significant morbidity and mortality. Such patients are commonly excluded from clinical trials. Bortezomib/dexamethasone (VD)-based regimens are the backbone of the treatment of newly diagnosed MM patients who present with severe RF even those requiring dialysis.

Long-term outcomes of primary systemic light chain (AL) amyloidosis in patients treated upfront with bortezomib or lenalidomide and the importance of risk adapted strategies.

Bortezomib and lenalidomide are increasingly used in patients with AL amyloidosis, but long term data on their use as primary therapy in AL amyloidosis are lacking while early mortality remains significant. Thus, we analyzed the long term outcomes of 85 consecutive unselected patients, which received primary therapy with bortezomib or lenalidomide and we prospectively evaluated a risk adapted strategy based on bortezomib/dexamethasone to reduce early mortality. Twenty-six patients received full-dose bortezomib/dexamethasone, 36 patients lenalidomide with oral cyclophosphamide and low-dose dexamethasone and 23 patients received bortezomib/dexamethasone at a dose and schedule adjusted to the risk of early death.

AChR-myasthenia gravis switching to double-seropositive several years after the onset.

We report an early onset AChR-myasthenia gravis (MG) with biphasic clinical course. The clinical "switch" from AChR-MG to MuSK-MG emerged 16 years after the onset and 11 years after thymectomy. MuSK antibodies were detected only by cell-based assay and only upon clinical "switch", while AChR antibodies remained positive and at high titers during the whole disease course.

Renal impairment is not an independent adverse prognostic factor in patients with multiple myeloma treated upfront with novel agent-based regimens.

Abstract Renal impairment (RI) is a common presenting complication of multiple myeloma associated with significant morbidity and early mortality, while it has been associated with inferior survival in patients treated with conventional regimens. We assessed the impact of RI in 203 unselected consecutive patients treated upfront with novel agents (thalidomide, lenalidomide, bortezomib). RI was assessed by the estimated glomerular filtration rate (eGFR).

Reversibility of renal failure in newly diagnosed patients with multiple myeloma and the role of novel agents.

The purpose of this analysis was to assess the effect of novel agent-based regimens on the improvement of renal impairment (RI) in newly diagnosed patients with multiple myeloma. Ninety-six consecutive patients with RI received conventional chemotherapy (CC)-based regimens (n=32), IMiDs-based regimens (n=47) or bortezomib-based regimens (n=17) as frontline therapy. Improvement of RI was more frequent in patients treated with novel agents (79% in IMiD- and 94% in bortezomib-treated groups versus 59% in CC-treated group; p=0.
