Dear Editor, Cold agglutinin disease (CAD) is an uncommon autoimmune hemolytic anemia characterized by the production of cold agglutinins (CA) [1]. CA exhibits the strongest affinity for the antigen at 0–4°C but binding may occur at temperatures approaching the normal body temperature of mammals, depending on the thermal amplitude of the antibody. Rituximab(More)
A 56-year-old man was admitted to our hospital with leukocytosis, anemia, and thrombocytopenia. Acute monoblastic leukemia was diagnosed. Two subsequent courses of consolidation chemotherapy consisted of conventional doses of cytarabine and intermediate-dose cytarabine. Intermediate-dose cytarabine was infused intravenously every 12 hr for 6 days. On day 15(More)
To study hematopoietic reconstitution in umbilical cord blood transplantation (CBT), bone marrow (BM) histology was investigated in 35 biopsies after bone marrow transplantation (BMT) and in 40 biopsies after CBT. BM biopsies were obtained at different times after transplantation and were evaluated for cellularity, number of megakaryocytes and CD34-positive(More)
Patients with Ph chromosome negative myeloproliferative disease (Ph-MPD) have an increased risk of vascular complications. It remains controversial whether patients with the JAK2 V617F mutation (V617F) exhibit increased risk, while recent growing evidence has shown a critical role for V617F in clonal erythropoiesis in Ph-MPD. We studied 53 patients with(More)
We investigated the oncogenic role of SETDB1, focusing on non-small cell lung cancer (NSCLC), which has high expression of this protein. A total of 387 lung cancer cases were examined by immunohistochemistry; 72% of NSCLC samples were positive for SETDB1 staining, compared to 46% samples of normal bronchial epithelium (106 cases) (p <0.0001). The percentage(More)
LNK (SH2B3) is an adaptor protein studied extensively in normal and malignant hematopoietic cells. In these cells, it downregulates activated tyrosine kinases at the cell surface resulting in an antiproliferative effect. To date, no studies have examined activities of LNK in solid tumors. In this study, we found by in silico analysis and staining tissue(More)
A 66-year-old woman presented with anemia in January 2006. She was admitted to our Department in February, after laboratory data showed pancytopenia and bone marrow biopsy reticulin fibrosis. The results of the diagnostic work-up, which included the anti-SS-A antibody, anti-SS-B antibody positivity and salivary gland scintigraphy, Schirmer test and Rose(More)
We analyzed a case with the blastoid variant of mantle cell lymphoma (MCL-BV), a rare subtype of B-cell lymphoma, presenting with marked hypercalcemia at diagnosis. Enzyme-linked immunosorbent assay (ELISA) showed elevated serum levels of interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-alpha), macrophage inflammatory protein-1alpha (MIP-1alpha), and(More)
A 44-year-old male patient was diagnosed with acute lymphoblastic leukemia (CD10+, CD19+, CD20 weak) and underwent unrelated bone marrow transplantation (uBMT) with a conditioning regimen of cyclophosphamide plus total body irradiation during first complete remission (CR). Twenty months post-uBMT, the serum creatinine level (Cre) increased gradually, up to(More)
