Recently, protocols using high-dose melphalan chemotherapy and autologous peripheral blood stem cell transplantation (HDM/SCT) have been developed for the treatment of patients with immunoglobulin light chain (AL) amyloidosis. Although peritransplantation mortality is greater than for other hematologic diseases, treatment leads to durable hematologic complete responses, improvements in organ fu...

Multiple myeloma and JAK2 positive chronic myeloproliferative neoplasms are hematologic malignancies with a completely different cellular origin. Two cases of simultaneous occurrence of multiple myeloma, one with primary myelofibrosis and another one with essential thrombocythemia are reported in this article. In such cases, an accurate diagnosis requires a molecular testing, including gene seq...

Organic solvents have long been recognized as being toxic to multiple organ systems. It is commonly known that exposure to organic solvents causes hematologic diseases, including hematologic cancers such as leukemia and lymphoma. A large body of literature has developed which shows that exposure to organic solvents causes kidney disease, especially chronic glomerulonephritis. A number of recent...

Tyrosine kinases phosphorylate proteins on tyrosine residues, producing a biologic signal that influences many aspects of cellular function including cell growth, proliferation, differentiation, and death. Constitutive or unregulated activity through mutation or overexpression of these enzymes is a common pathologic feature in many acute and chronic leukemias. Inhibition of tyrosine kinases rep...

Hematopoietic stem cell transplantation (HSCT) is the first field where human stem cell therapy was successful. Flooding interest on human stem cell therapy to cure previously incurable diseases is largely indebted to HSCT success. Allogeneic HSCT has been an important modality to cure various diseases including hematologic malignancies, various non-malignant hematologic diseases, primary immun...

haematologica/the hematology journal | 2007; 92(12) | 1589 | Bor T-lymphocyte-mediated autoimmune disorders may lead to clinical disease characterized by low blood cell counts. The term autoimmune cytopenias has been collectively applied to this heterogeneous group of disorders. After the introduction of the humanized, chimeric monoclonal anti-CD20 antibody, rituximab, as a powerful therapeutic...

Hematologic complications of HIV disease are commonly encountered by physicians and other health-care workers caring for patients infected with this virus. Ineffective hematopoiesis, infiltrative diseases of the bone marrow, nutritional deficiencies, peripheral destruction of blood cells secondary to splenomegaly or immune dysregulation, and drug effects all contribute to the variety of hematol...

Five patients, four women and one man, age 32-8- yr, all whites, had refractory anemia with the same abnormal bone marrow karyotype, i.e., a partial deletion of the long arm of the No. 5 chromosome. The hematologic syndrome was practically the same in these five cases. Examination of the blood revealed a moderate to severe, generally macrocytic anemia with slight leukopenia but normal or elevat...

Amyloidosis comprises a rare spectrum of protein deposition diseases that diffusely or focally affect any organ. Amyloid's variable clinical presentation and nonspecific disease course often cause it to evade early diagnosis. This pictorial essay aims to familiarize radiologists with the pathophysiology of amyloidosis, to describe the basic classifications of amyloidosis, and to use multimodali...
