Patients with reduced ability to metabolize environmental carcinogens or toxins may be at risk of developing aplastic anemia. Glutathione S-transferase (GST) has been implicated in detoxifying mutagenic electrophilic compounds. This study asked whether the homozygous gene deletions of GSTM1 and GSTT1 affect the likelihood of developing aplastic anemia. The incidence of GSTM1 and GSTT1 gene dele...

The mechanism which produces marrow failure in idiopathic aplastic anemia is still unknown. Recent investigations have suggested the crucial role of NK cells in the regulation of normal hematopoiesis. In this study, the cytotoxic activity of mononuclear cells from human bone marrow and peripheral blood was examined against three NK-sensitive target cell lines in 15 patients with aplastic anemia...

Aplastic anemia is an uncommon complication of thymoma and is extremely infrequent after the surgical removal of a thymic tumor. Aplastic anemia is a result of marrow failure and is characterized by peripheral pancytopenia and severely depressed marrow cellularity; it may be an autoimmune manifestation of thymoma. As thymoma-associated hematological dyscrasias, which include pure red cell aplas...

The International Bone Marrow Transplant Registry reported experience from 179 transplant teams worldwide on patients treated with bone marrow transplantation for severe aplastic anemia. The cohort consisted of 470 patients (283 male, 187 female), mean age 20 years, who received an HLA-identical sibling bone marrow transplant for aplastic anemia between 1988 and 1992. The etiology of aplastic a...

Aplastic anemia therapy remains difficult, due to lack of effective treatment regimens. In recent years, Huangqi injection for the adjunctive therapy of aplastic anemia has been reported in many clinical trials. Considering that Huangqi injection may be a novel approach to aplastic anemia treatment, we conducted a meta-analysis of clinical controlled trials to assess the clinical value of Huang...

Aplastic anemia is a bone marrow failure syndrome characterized by peripheral cytopenias and hypocellular bone marrow. Although aplastic anemia is idiopathic in most cases, rheumatic diseases such as systemic lupus erythematosus are recognized as causes of aplastic anemia, with their possible etiological mechanisms being T and B lymphocyte dysfunction and pro-inflammatory cytokines and autoanti...

The majority of cases of aplastic anemia, a rare previously lethal disease, are of unknown etiology. Nevertheless, for the past 3 decades, case reports and case series of aplastic anemia have suggested an etiologic association between aplastic anemia and pesticide exposure. A review of the medical literature, including basic science literature, confirms a possible etiologic association between ...

Aplastic anemia is an immunosuppressed illness that difficult to treat. Planning for future renal transplantation in such individuals makes the situation more challenging since we must continue immunosuppression necessary a stable allograft while also ensuring aplastic remission.

I N 1961, WE REPORTED 20 cases of severe aplastic anemia in which infusions of allogenic ( homologous ) bone marrow had been used as one of the therapeutic methods.1 Seven of these patients made apparently complete recoveries; whether coincidentally or in rlationship to the marrow infusions is not clear. Since then, the use of allogeneic bone marrow infusions has been wellnigh discarded for the...

We report an 18 year old boy with Aplastic anemia complicated by serious fungal rhinosinusitis. Despite prompt treatment and early repeated surgical debridements, he died after about more than 6 weeks of hard challenges with fungal infections. Current strategies against invasive fungal infections (IFIs) in patients with Aplastic anemia may be inadequate for the management of serious complicatio...
