Liver function during continuous subcutaneous deferoxamine therapy was investigated in 29 patients with homozygotic beta-thalassaemia. Average duration of treatment was 26 months (range 8-51 months). A decrease in haemosiderosis and an improvement in liver function was observed in 27 patients: Mean liver density, determined by computed tomography, decreased from 98 to 84 HU, mean serum ferritin concentration fell from 8028 to 3661 ng/ml, mean serum GOT activity from 44 to 13 U/l and GPT from 51 to 16 U/l. Mean cholinesterase activity, reflecting the improved synthetic activity of the liver, increased from 4063 to 4530 U/l.

The activity of 18 red blood cell (RBC) enzymes and reduced glutathione (GSH) content were measured in 70 normal subjects, in 50 heterozygous beta-thalassaemia carriers and in 50 non-thalassaemic patients with haemolytic anaemia and high reticulocyte counts. In addition, pyrimidine 5'nucleotidase (P5N) activity was also determined in 34 patients with hypochromic, microcytic, iron deficiency anaemia. beta-Thalassaemia trait was associated with an increase in almost all of the enzyme activities, except for 2,3-bisphosphoglycerate synthetase (BPGS) and glutathione reductase (GR) which were normal and for acetylcholinesterase (AChE) and P5N which were slightly and markedly decreased respectively. The increases in enzyme activities were similar to those observed in patients with non-thalassaemic reticulocytosis except for glyceraldehydephosphate dehydrogenase (GAPD), phosphoglyceratekinase (PGK), pyruvate kinase (PK), glutathione peroxidase (GPX) and adenylate kinase (AK) which were higher than in non-thalassaemic group of patients with increased number of reticulocytes. No correlation was found between the severity of P5N deficiency and the intensity of basophilic stippling which was present in 46 of 50 thalassaemic carriers here studied. In addition, GSH content and UV absorption spectra of deproteinized thalassaemic RBC extracts were also found to be normal. The present findings provide further information on the metabolic status of RBC in beta-thalassaemia trait and suggest a possible molecular explanation for the frequently observed basophilic stippling in this disease.
