Major surgery in a patient with pancytopenia might be associated with increased surgical risks, especially for bleeding and infection. A 66-yr-old man was admitted to the hospital due to shortness of breath. His dyspnea was classified by the New York Heart Association (NYHA) as functional class III. Prior to admission, he had a 5-yr history of medical management for idiopathic aplastic anemia. ...

A study of the occurrence of aplastic anemia among atomic bomb survivors in Nagasaki and Hiroshima, Japan was made from a review of a series of 6327 autopsies from 1949 to June 1967 and the late effects of ionizing radiation were evaluated. There were 340 cases reviewed independently by a team of hematologists and pathologists. Of the 45 cases documented as aplastic anemia, 42 were definite and...

BACKGROUND Acquired aplastic anaemia is one of the important causes of pancytopenia. This study was conducted to observe the mode of presentation of acquired aplastic anaemia and to find out its possible etiological factors. METHODS It is a hospital based descriptive study of 100 patients of acquired aplastic anaemia. RESULTS Out of 100 patients 60 were male and 40 female. Majority (44%) of...

Coinfusion of hematopoietic and mesenchymal stem cells is more effective than hematopoietic stem cell transplantation alone. It is necessary to explore a safe and routine mixed stem cell intraperitoneal transplantation method. Multiplacentas pooled cells were intraperitoneally injected into a radiation- and immunity-induced mouse aplastic anemia model with single time. Then, mouse survival time...

BACKGROUND Mutations in TERC, the gene for the RNA component of telomerase, cause short telomeres in congenital aplastic anemia and in some cases of apparently acquired hematopoietic failure. We investigated whether mutations in genes for other components of telomerase also occur in aplastic anemia. METHODS We screened blood or marrow cells from 124 patients with apparently acquired aplastic ...

The clinical and histopathological distinctions between inherited versus acquired bone marrow failure and myelodysplastic syndromes are challenging. The identification of inherited bone marrow failure/myelodysplastic syndromes is critical to inform appropriate clinical management. To investigate whether a subset of pediatric and young adults undergoing transplant for aplastic anemia or myelodys...

In aplastic anemia, immune destruction of hematopoietic cells results in bone marrow failure. Type 1 cytokines, especially IFN-gamma, have been implicated in the pathophysiology of T-cell-mediated, Fas-mediated stem cell apoptosis of hematopoietic cells. Here, we show that the transcription factor T-bet (T-box expressed in T cells) is increased in T cells from patients with aplastic anemia. Pat...

Background: Aplastic anemia is a rare but serious disorder. More than 70% cases of anemia are idiopathic. This study was conducted to find out the possible etiological factors in our set up. Methodology: This descriptive study was carried out in Department of Medicine, Khyber Teaching Hospital, Peshawar from January, 2005 to December, 2009. One hundred patients with acquired aplastic anemia wer...

The bone marrow failure states, aplastic anemia and myelodysplastic syndrome, are characterized by reticulocytopenic anemia, with variable neutropenia and thrombocytopenia. The bone marrow biopsy is very hypocellular in aplastic anemia, but it is usually hypercellular in myelodysplastic syndrome. Marrow cytogenetic abnormalities are present in approximately half of myelodysplastic syndrome pati...
