A 62-year-old female was admitted to our hospital with suspected acute leukaemia and after investigation we diagnosed acute myeloblastic leukaemia (AML-M1). The patient's blood type was found to be the very rare Bombay type and surveillance of her relatives showed the same blood type in her male cousin on her mother's side. Alongside chemotherapy the patient received 4000 ml of frozen Bombay-type red cells, 1400 ml of concentrated red cells in manitol adenine phosphate solutions and 360 units of type O concentrated platelets without marked effects. The anti-H antibody was initially at 128 dilution but for unknown reasons increased to 2048 dilution after remission of AML-M1. About 3 months after hospitalization the patient died of Cryptococcus neoformans pneumonia despite strict precautions against infection. Although AML-M1 is a common adult leukaemia and is chemosensitive to anti-leukaemic drugs, neither AML-M1 in a patient with Bombay-type red cells nor its treatment with chemotherapy and transfusion with type Oh frozen red cells have previously been reported.
Simultaneous treatment with peripheral blood stem-cell (PBSC) transplantation and intensive chemotherapy was evaluated in a case of non-Hodgkin's lymphoma (NHL) with poor prognosis. A 59-year-old male diagnosed with a high-grade, anaplastic large-cell (Ki-1) NHL, involving fractures in the left hip, underwent computed tomography and gallium scintigram surveillance. The patient received chemotherapy with epirubicin hydrochloride, cyclophosphamide, vincristine and prednisolone, and the fractured hip bone was repaired following the first course of chemotherapy. After the second and third courses of chemotherapy, PBSCs were harvested and cryopreserved. The patient then received a further course of chemotherapy and PBSC transplantation was conducted using infused cells consisting of 9.63 x 10(6)/kg CD34 cells and 2.24 x 10(5)/kg granulocyte macrophage colony-forming units. Recovery of platelet and white blood cell counts occurred 10 and 8 days, respectively, after PBSC infusion and the patient remains well.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
