Patients with AL-amyloidosis are treated at present by conventional or large-dose chemotherapy with autologous transplantation of haematopoietic stem cells, similarly as patients with multiple myeloma. Only the timing of treatment is different. In myeloma treatment is usually indicated only in clinical stage II or III, in clinical stage I only in case of adverse prognostic factors. In AL-amyloidosis treatment is indicated immediatelyafter establishment of the diagnosis. It was found that high-dose chemotherapy with autologous transpantation of haematopoietic cells is at present the most effective treatment for selected patients with not advanced forms of primary systemic AL-amyloidosis. Allogenic transplantation of the liver is treatment of choice in ATTR amyloidosis. In AA-amyloidosis the basis of treatment is removal or suppression of the chronic inflammatory process, possibly colchicin administration.
