Estimation of ferrokinetic parameters by a mathematical model in patients with primary acquired sideroblastic anaemia.

Ferrokinetic parameters were estimated in eight patients with primary acquired sideroblastic anaemia (PASA) by means of a mathematical model of iron kinetics. Both plasma 59Fe clearance and red cell utilization curves were used to identify the model parameters. The close agreement between experimental and theoretical data proved that the model can describe iron kinetics in sideroblastic anaemia. Ineffective erythropoiesis was found to be major factor in the production of the anaemia. Various degrees and patterns of peripheral haemolysis were observed. The storage iron was always markedly increased and a large non-erythroid iron turnover was calculated in the most severely affected patients. The results are compared with present knowledge of erythropoiesis in PASA.

Iron kinetics and erythropoiesis in Fanconi's anaemia.

Ferrokinetic studies were carried out in 4 patients with Fanconi's anaemia (FA). Experimental data were analysed by means of a mathematical model of iron kinetics in order to obtain a quantitative assessment of effective and ineffective erythropoietic activity, mean red cell lifespan, and non-erythroid iron turnover. The major pathogenetic mechanism of the anaemia appeared to be relative marrow failure, i.e. a reduction in the proliferative capacity of the erythroid marrow. The role of ineffective erythropoiesis was of minor importance. On the basis of the results obtained both the pathogenesis and the natural course of the disease are discussed.
