An amyloidosis is a group of diseases characterized by the deposition in the organs and tissues of a particular protein of the amyloid fibrillar structure. The clinical picture of amyloidosis is diverse, the clinic depends on the involvement of a particular organ in the pathological process, and the determining factor in the choice of treatment tactics is to establish the cause of its development. The article presents a clinical case of amyloidosis associated with multiple myeloma. The features of this clinical case are presented as an initially uncertified nosological form of heart disease with the leading syndrome of cardiac insufficiency, a relapsing course of pleurisy and an absence of kidney damage under conditions of proven amyloidosis. Diagnosis of secondary AL-amyloidosis in multiple myeloma is challenging and is based on histological and immunohistochemical studies of the bone marrow, secretion of Bens-Jones λ-protein. The most effective treatment method in young patients is the protocols for the therapy of multiple myeloma (VCD courses) for patients-candidates for autologous transplantation of hematopoietic stem cells (auto-THSC) with its subsequent implementation.

Key words: AL-amyloidosis, multiple myeloma, heart disease in amyloidosis, cardiac insufficiency.
