Primary acquired sideroblastic anaemia: response to treatment with pyridoxal-5-phosphate.
نویسندگان
چکیده
A 72-year-old woman with primary sideroblastic anaemia showed no response to treatment with pyridoxine. When she was given pyridoxal-5-phosphate there was a prompt reticulocyte response and sustained symptomatic improvement with satisfactory control of the anaemia.

A fluorimetric method for the measurement of pyridoxal and pyridoxal phosphate in human plasma and leucocytes, and its application to patients with sideroblastic marrows.
A highly sensitive fluorimetric assay for the measurement of pyridoxal and pyridoxal phosphate in biological tissues is described. The method involves the enzymic hydrolysis of pyridoxal phosphate to pyridoxal. The pyridoxal (free or total) is separated on an anion-exchange column, concentrated by cation-exchange chromatography and reacted with potassium cyanide under slightly alkaline conditio...
متن کاملThe measurement of serum pyridoxal by a microbiological assay using Lactobacillus casei.
A new method has been developed for the assay of serum pyridoxal using L. casei. Bound pyridoxal phosphate in serum is converted by acid hydrolysis to pyridoxal for which this organism is specific. This method proved to be considerably more sensitive than other methods so far reported in the literature. Serum pyridoxal concentrations were measured in 151 control subjects aged 17 to 80 years. Th...
متن کاملIdiopathic acquired sideroblastic anaemia transforming to acute myelosclerosis.
A case of idiopathic acquired sideroblastic anaemia transforming to acute myelofibrosis is reported. The appearance of atypical megakaryocytic proliferation in idiopathic acquired sideroblastic anaemia may presage the development of an acute myelofibrotic phase of this usually chronic disease.
متن کاملBone marrow delta-aminolaevulinate synthase deficiency in a female with congenital sideroblastic anemia.
Heme biosynthesis was examined in erythroid tissue of a 4-yr-old girl with severe sideroblastic anemia since infancy, as documented by the presence of intramitochondrial deposits of iron in erythroblasts. Free red cell protoporphyrin, urinary porphyrins, and activities of erythrocyte porphobilinogen synthase, uroporphyrinogen 1 synthase, aspartate aminotransferase, and pyridoxine kinase were no...
متن کاملRed cell aspartate aminotransferase saturation with oral pyridoxine intake.
CONTEXT AND OBJECTIVE The coenzyme of aspartate aminotransferase is pyridoxal phosphate, generated from fresh vegetables containing pyridoxine. Vitamin B6-responsive sideroblastic anemia, myelofibrosis and Peyronies syndrome respond to high pyridoxine doses. The objective was to investigate the oral pyridoxine oral dose that would lead to maximized pyridoxal phosphate saturation of red cell asp...
