Efficacy of bortezomib therapy for extramedullary relapse of myeloma after autologous and non-myeloablative allogeneic transplantation.

We report the successful use of bortezomib to treat a patient with multiple myeloma (MM) who had extramedullary relapse (paraspinal and thoracic masses and multiple cranial nerve palsy) after autologous and non-myeloablative allogeneic hematopoietic stem cell transplantation (HSCT).

Successful treatment of hematological and extramedullary relapse of MLL-positive acute lymphoblastic leukemia after bone marrow transplantation using donor leukocyte infusion.

Low response rates (range: 0-33%) were reported in acute lymphoblastic leukemia (ALL) patients who relapsed after bone marrow transplantation (BMT) and received donor leukocyte infusions (DLI). We describe an ALL patient who presented with a relapse in blood, bone marrow, breast, and axillary nodes 3 months after BMT from an unrelated donor. She achieved a second hematological complete remission (CR) after chemotherapy, with persistence of MLL-AF4 transcript in the bone marrow.

Endogenous endophthalmitis following disseminated fungemia due to Fusarium solani in a patient with acute myeloid leukemia.

We report the case of a young man with a resistant acute myeloid leukemia (AML) who developed a disseminated fungemia due to Fusarium solani involving the skin and lungs, during the neutropenic phase following a chemotherapy course. Despite continuous therapy with liposomal amphotericin B, he developed a bilateral endophthalmitis that rapidly evolved to complete blindness. The patient underwent two procedures of vitrectomy, with detection of F.

Activity of all-trans-retinoic acid in a case of central nervous system extramedullary relapse of acute promyelocytic leukemia.

We describe a patient with an acute promyelocytic leukemia (APL) previously treated with two courses of cytarabin, idarubicin and all-trans retinoic acid (ATRA), who presented a medullary and meningeal relapse after 8 months of complete remission. A diagnosis of central nervous system (CNS) involvement was based on the appearance of APL blasts in the cerebrospinal fluid (CSF); magnetic resonance (MR) imaging was negative. The neurological symptoms were not evident at the time of recognition of the medullary recurrence, but appeared a few days later, when the patient had already received a reinduction treatment.

Early chemosensitivity to VAD regimen predicts a favorable outcome after autologous stem cell transplantation in multiple myeloma.

We report that early chemosensitivity, defined by a greater than 50% reduction of M-component and plasma-cell marrow infiltration, after 2 cycles of VAD was correlated with a favorable outcome following autologous stem cell transplantation in 46 patients with newly diagnosed multiple myeloma submitted to high-dose therapy.

B-cell depletion with rituximab as treatment for immune hemolytic anemia and chronic thrombocytopenia.

Background And Objectives: Rituximab reacts specifically with the CD20 antigen and induces B-cell depletion. This could interfere with the production of autoantibodies in some immune diseases. The objective of this study was to assess the effects of rituximab in autoimmune hemolytic anemia and thrombocytopenia.
