Where can amyloidosis be found?
Amyloid deposits can be found in abdominal fat, minor salivary glands, and bone marrow, and most patients can be spared biopsy of the involved organ. However, if amyloidosis is deemed probable, for a prompt start of treatment, organ biopsy should not be deferred.
What is an AL cell?
Abstract. In amyloid light chain (AL) amyloidosis, a small B-cell clone, most commonly a plasma cell clone, produces monoclonal light chains that exert organ toxicity and deposit in tissue in the form of amyloid fibrils. Organ involvement determines the clinical manifestations, but symptoms are usually recognized late.
What is a PC clone?
In systemic AL amyloidosis a PC clone, or, less frequently, a lymphoplasmacytic or marginal zone lymphoma, produces a toxic LC that causes organ dysfunction and damage and forms amyloid fibrils in tissues. In contrast, localized deposition of LCs causes nodules to develop in the skin and in the respiratory, urinary, and gastrointestinal tracts, with local symptoms and a benign course that usually is managed with local treatment. 1 In systemic AL amyloidosis, the PC clone is usually small (median infiltrate, 10%), and presents t (11;14) and gain 1 (q21) in ∼50% and 20% of clones, respectively, whereas high-risk aberrations are uncommon. 2,3 Patients whose PC clones harbor t (11;14) have a worse outcome with bortezomib and immunomodulatory drugs (IMiDs), whereas gain 1 (q21) is associated with poorer results with oral melphalan. 3-5
Can amyloidosis be detected by NT-proBNP?
Symptoms are often misinterpreted and recognized late. When they appear, organ involvement is often irreversible. However, cardiac and renal amyloidosis can be detected by NT-proBNP and albuminuria before overt heart failure and nephrotic syndrome arise. Moreover, a monoclonal component can be found at least 4 years before diagnosis. 13 Therefore, hematologists can intercept, diagnose, and treat patients during the presymptomatic stage, by including biomarkers of organ involvement in the monitoring panel of subjects with monoclonal gammopathy of undetermined significance (MGUS). 14 Recent findings suggest that CMR can detect very early cardiac involvement 15 ; hence, CMR may be used as a confirmatory test in subjects with MGUS in whom elevated NT-proBNP is found. However, the cost effectiveness of this approach is unknown. A diagnostic flowchart for AL amyloidosis is reported in Figure 1.
Should patients be shifted to second line treatment?
Patients who do not attain satisfactory response should be shifted to second-line treatment as early as possible. So far, there is no evidence to support maintenance therapy in responders, who should be closely followed. However, there is no consensus on when treatment should be started at relapse. We lack validated hematologic progression criteria, and the definition of PFS varies in different studies. Organ progression criteria predict shorter patient and renal survival and such progression should not be awaited before starting rescue therapy. 12,17 In general, organ progression is preceded by FLC increases, which can be small and should not be disregarded. 32 Other factors to be considered are FLC level and severity of organ involvement at diagnosis, as well as the quality of response to previous treatment.
Is Bortezomib good for AL amyloidosis?

What is the name of the disease in which a B cell clone is present?
In amyloid light chain (AL) amyloidosis, a small B-cell clone, most commonly a plasma cell clone, produces monoclonal light chains that exert organ toxicity and deposit in tissue in the form of amyloid fibrils. Organ involvement determines the clinical manifestations, but symptoms are usually recognized late. Patients with disease diagnosed at advanced stages, particularly when heart involvement is present, are at high risk of death within a few months. However, symptoms are always preceded by a detectable monoclonal gammopathy and by elevated biomarkers of organ involvement, and hematologists can screen subjects who have known monoclonal gammopathy for amyloid organ dysfunction and damage, allowing for a presymptomatic diagnosis. Discriminating patients with other forms of amyloidosis is difficult but necessary, and tissue typing with adequate technology available at referral centers, is mandatory to confirm AL amyloidosis. Treatment targets the underlying clone and should be risk adapted to rapidly administer the most effective therapy patients can safely tolerate. In approximately one-fifth of patients, autologous stem cell transplantation can be considered up front or after bortezomib-based conditioning. Bortezomib can improve the depth of response after transplantation and is the backbone of treatment of patients who are not eligible for transplantation. The daratumumab+bortezomib combination is emerging as a novel standard of care in AL amyloidosis. Treatment should be aimed at achieving early and profound hematologic response and organ response in the long term. Close monitoring of hematologic response is vital to shifting nonresponders to rescue treatments. Patients with relapsed/refractory disease are generally treated with immune-modulatory drugs, but daratumumab is also an effective option.
Is Bortezomib good for AL amyloidosis?
Bortezomib can improve the depth of response after transplantation and is the backbone of treatment of patients who are not eligible for transplantation. The daratumumab+bortezomib combination is emerging as a novel standard of care in AL amyloidosis.
How to treat amyloidosis?
Supportive treatments are the measures taken to alleviate specific problems and symptoms caused by amyloid deposits in various organs and they are very important in all amyloid types. For example, if the heart or kidneys are affected, patients may need to take a diuretic (water excretion pill), restrict the amount of salt in their diet, or wear elastic stockings and elevate their legs to help lessen the amount of swelling. When the gastrointestinal tract is involved, dietary changes and certain medications can be tried to help symptoms of diarrhea and stomach fullness. These and other supportive therapies have increased the length and quality of life for many individuals with amyloidosis.
