Constitutional Hypoplastic Anemia

Hypoplastic anemia due to atabrine.

Congenital hypoplastic anemia inhibition of erythropoiesis by sera from patients with congenital hypoplastic anemia.

An in vitro marrow culture assay designed to measure erythropoietic capability was used to ascertain the presence of an inhibitor in the sera of patients with congenital hypoplastic anemia (CHA). Marrow cells from nine anemic CHA patients responded to the stimulatory effect of exogenous erythropoietin (EPO) by an increase in heme synthesis in the presence of normal serum. The effect on heme syn...

Lymphocyte dysfunction in congenital hypoplastic anemia.

Congenital hypoplastic anemia (Diamond-Blackfan syndrome) is thought to involve the erythropoietic cell line alone. In this study, the evaluation of lymphocyte function in five patients with this syndrome revealed a number of abnormalities. Peripheral blood T lymphocyte percentages as assessed by monoclonal antibodies were decreased in three patients. T-helper/T-suppressor cell (OKT4:OKT8) rati...

Cortisone and ACTH in Hypoplastic Anemia *

For many years hypoplastic or aplastic anemia has been identified with a confusing group of pancytopenias which are refractory to treatment. Recently The Committee for Clarification of the Nomenclature of Cells and Diseases of the Blood and Blood-forming Organs has redefined the term hypoplastic anemia and discarded the term aplastic anemia."3 Hypoplastic anemia is defined by this committee as ...

Treatment of hypoplastic anemia in mice with placental transplants.

A genetic mutation in mice (W/Wv) causes an autosomal recessive disease characterized by hypoplastic anemia which lasts throughout life. Double-dominant W/Wv anemic mice were sublethally irradiated to facilitate repopulation of marrow with transplanted cells and were injected intravenously with suspensions of 5-10 million placental cells of 15 days gestation derived from normal, isogeneic donor...
