The molecular genetics of sideroblastic anemia

Sideroblastic anemia.

When first defined 50 years ago, sideroblastic anemia (SA) was already recognized to occur in heterogeneous settings, including as familial or acquired disease. The spectrum of SA has since become considerably expanded with respect to distinct clinical phenotypes as well as discrete causes. The singular feature that typifies all forms of SA and is required for initial diagnosis is the presence ...

Severe isoniazid related sideroblastic anemia

Isoniazid induced sideroblastic anemia is a rare event. We report case of a 45 year old Caucasian women with development of severe anaemia 4 month after introduction of Isoniazid as part of Tuberculosis treatment. While haemoglobin fell to 47 g/L and erythrocyte count to 1.5 G/L, reticulocytes were very low (reticulocyte production index of 0.48), but bone marrow aspirate showed an accelerated ...

Pneumoviruses: Molecular Genetics and Reverse Genetics

Pneumoviruses are responsible for significant respiratory disease in their hosts and represent a major problemfor human and animal health. Pneumoviruses are members of the family Paramyxoviridae, subfamilyPneumovirinae and the virus particles consist of a negative-sense, nonsegmented RNA genome within a helical nucleocapsid structure enveloped in a lipid membrane derived from the ho...

Natural history of idiopathic refractory sideroblastic anemia.

We analyzed the natural history of idiopathic refractory sideroblastic anemia (IRSA) in 37 patients studied between 1969 and 1986. Although erythroid abnormalities were prominent in all, 12 patients also showed involvement of the granulocytic and/or megakaryocytic cell lines, and nonrandom chromosomal aberrations were observed in five of 23 patients studied for such defects. Measurements of ery...
