Coculture studies of 16 untransfused patients with aplastic anemia

Coculture studies of 16 untransfused patients with aplastic anemia.

We studied the effects of peripheral blood lymphocytes from 16 untransfused patients with severe aplastic anemia (AA) of diverse etiologies on the growth of granulocyte-macrophage colonies from normal marrows. Normal lymphocytes in our system increased the number of granulocytic colonies by 31 +/- 6% (mean +/- SEM). Lymphocytes from 3 of 16 untransfused AA patients significantly inhibited growt...

Aplastic anemia: management of adult patients.

The primary therapeutic approach to acquired aplastic anemia (AA) in older adults differs from the primary approach used in children and younger adults because in the former group, the results of allogeneic bone marrow transplantation (BMT) are less favorable. With increasing age of the patients, immunosuppressive therapy with antithymocyte globulin (ATG) and cyclosporine (CsA) constitutes the ...

Aplastic anemia: management of pediatric patients.

Aplastic anemia is a term describing the common findings of pancytopenia and marrow hypoplasia arising from a variety of disease states, including acquired aplastic anemia and a variety of congenital marrow failure states. The management of children with these disorders has been confounded by difficulties of diagnosis. The availability of molecular testing has assisted in partial resolution of ...

Telomere length in leukocyte subpopulations of patients with aplastic anemia.

In most human cells, the average length of telomere repeats at the ends of chromosomes provides indirect information about their mitotic history. To study the turnover of stem cells in patients with bone marrow failure syndromes, the telomere length in peripheral blood granulocytes and lymphocytes from patients with aplastic anemia (AA, n = 56) and hemolytic paroxysmal nocturnal hemoglobinuria ...
