The term amyloidosis refers to a group of disorders in which protein fibrils accumulate in certain organs, disrupt their tissue architecture, and impair the function of the effected organ. The clinical manifestations and prognosis vary widely depending on the specific type of the affected protein. Immunoglobulin light-chain (AL) amyloidosis is the most common form of systemic amyloidosis, characterized by deposition of a misfolded monoclonal light-chain that is secreted from a plasma cell clone. Demonstrating amyloid deposits in a tissue biopsy stained with Congo red is mandatory for the diagnosis...

Background: Immunoglobulin light-chain amyloidosis (AL amyloidosis) is a rare and often fatal disease for which there is currently no treatment approved by the US Food and Drug Administration or the European Medicines Agency. Treatment options, which are typically based on therapies for multiple myeloma and are used off-label, are associated with substantial adverse events (AEs). Because the severity of AEs is often determined by clinicians, evaluations of treatment tolerability may not fully consider patients' own experience with treatment...

In light-chain (AL) amyloidosis, the depth of hematologic response to treatment is associated with improved survival and organ responses. We conducted a clinical trial utilizing bortezomib in induction and in conditioning with melphalan prior to stem cell transplantation (SCT) for AL amyloidosis. The results of this clinical trial with a median follow-up of 36 months have been reported previously. Here we report the long-term results of this clinical trial with a median follow-up of 77 months. The objectives of this follow-up report are to describe survival, durability of hematologic and organ responses, and relapse rates...

CD38 antigen is highly and uniformly expressed on plasma cells and thus represents an ideal target for the treatment of multiple myeloma (MM) with anti-CD38 monoclonal antibodies (mAbs). Daratumumab is the most advanced anti-CD38 mAb in the clinical development with approval in several indications, nevertheless isatuximab that targets completely different epitope of CD38 molecule is also very promising drug. Anti-CD38 possess pleiotropic mechanism of action that have been described also in other mAbs, but quite specific, novel and very important seems to be the immunomodulatory effect provided by depletion of several CD38+ immunosuppressive immune cell populations...

Plasma cell dyscrasias are a rare heterogeneous group of hematological disorders which are more prevalent in the older part of the population. The introduction of novel agents, improved understanding of disease biology and better supportive management have improved outcomes considerably and in the era of the aging population the question of how to best manage older patients with plasma cell dyscrasias has never been more relevant. Data on how to treat these patients comes mostly from subgroup analysis as they are underrepresented in clinical trials...

RATIONALE: Immunoglobulin light chain amyloidosis (AL amyloidosis) is characterized by the deposition of abnormal amyloid protein produced by a pathological plasma cell clone in various organs and soft tissues. Hematopoietic stem cell transplantation (HSCT) is an effective way to treat AL amyloidosis. Psoriasis is a common autoimmune disease (AID) and HSCT is a potential treatment for severe AIDs. We report a rare case of AL amyloidosis coincidence with psoriasis obtained continuous complete remission of the 2 diseases by autologous hematopoietic stem cell transplantation (ASCT)...

Despite substantial improvements following the introduction of novel agents and antibodies, amyloid light-chain (AL)-amyloidosis still carries a grim prognosis. Here, we report on the case of a severely frail 86-year-old patient suffering from monoclonal gammopathy of renal significance (MGRS)-associated AL-amyloidosis with a diuretic-refractory nephrotic syndrome. In this patient, treatment with bortezomib-dexamethasone effectively induced a serological response, but was unfortunately poorly tolerated and failed to promote renal recovery fast enough to prevent secondary complications...

BACKGROUND: Cardiac Amyloidosis (CA) pertains to the cardiac involvement of a group of diseases, in which misfolded proteins deposit in tissues and cause progressive organ damage. The vast majority of CA cases are caused by light chain amyloidosis (AL) and transthyretin amyloidosis (ATTR). The increased awareness of these diseases has led to an increment of newly diagnosed cases each year. METHODS: We performed multiple searches on MEDLINE, EMBASE and the Cochrane Database of Systematic Reviews...

Systemic light-chain (AL) amyloidosis is a rare hematologic disorder where proteins infiltrate tissues leading to organ failure and death. Cardiac involvement, present in ∼70% of patients, determines stage and prognosis of the disease, with advanced involvement having a median survival of six months. The treatment of light-chain amyloidosis is directed at recovering organ function with therapeutic strategies following those of multiple myeloma with plasma cell-directed therapies. The use of single agent daratumumab has been reported in light-chain amyloidosis achieving rapid and deep responses...

The kidney is the most common organ involved in systemic amyloidosis. We aimed to study etiology and clinicopathological profile of renal amyloidosis. This was a retrospective study of 40 consecutive adult patients with biopsy-proven renal amyloidosis evaluated over a period of two years. Emphasis was given to describing the clinical presentation, renal function, proteinuria, type of amyloidosis, and its etiology. Mean age of the study cohort was 44 ± 15 years (with a male-to-female ratio of 3:1). Amyloid A (AA) amyloidosis was the most common type of amyloidosis observed in 72...

Dysphagia is an uncommon presentation of systemic immunoglobulin light-chain (AL) amyloidosis with multiple myeloma (MM). Gastrointestinal (GI) involvement usually manifests with altered motility, malabsorption or bleeding. Furthermore, patients identified with GI amyloidosis, without previous diagnosis of a plasma cell disorder, are extremely rare. We report an elderly woman who presented with acute on chronic cardiac dysfunction, sick sinus syndrome and acute renal failure. While admitted, she developed intermittent dysphagia to both solids and liquids...

AL amyloidosis (light chain; previously also called primary amyloidosis) is a systemic disease characterized by an amyloid deposition process affecting many organs, and which still has unsatisfactory survival of patients. The monoclonal light chains kappa (κ) or lambda (λ) or their fragments form the fibrils that deposit and accumulate in different tissues. Renal involvement is very frequent in AL amyloidosis and can lead to the development of nephrotic syndrome followed by renal failure in some cases. AL amyloidosis ultimately leads to destruction of tissues and progressive disease...

Immunoglobulin (Ig) light chain (AL) amyloidosis is a clonal plasma cell disorder characterized by misfolded Ig light chain deposition in vital organs of the body, resulting in proteotoxicity and organ dysfunction. Owing to its diverse clinical presentations and a tendency to mimic common medical conditions, AL amyloidosis is often diagnosed late and results in dismal outcomes. Early referral to a specialized center with expertise in management of AL amyloidosis is always recommended. The availability of sensitive biomarkers and novel therapies is reforming our approach to how we manage AL amyloidosis...
