Background and objectives: A progressive accumulation of body iron easily occurs as a result of long-term transfusions in patients with anaemia of genetic disorders such as thalassaemia. Iron deposit in liver biopsy sections was studied in beta-thalassaemia major patients to assess the grade of liver siderosis and to correlate the grade with amount of blood transfused.

Materials and methods: Beta-thalassaemia major patients having splenomegaly and selected for splenectomy were enrolled. Liver biopsy was taken from every patient during the splenectomy. Liver tissue was sectioned and stained with Perls’ prussian blue method for the presence of iron deposition. The degree of iron deposition was expressed as grades of siderosis from 0 to 4.

Results: A total of 30 beta-thalassemia patients were enrolled in the study. Out of 30 patients, 7 were males (23.3%) and 23 females (76.7%). The mean age of patients was 15.2 ± 1.4 years. The mean serum iron and ferritin levels of the study cases were above the normal range. Blood received by all patients was 51.5 ± 11.6 units (range 31 to 88 units). Out of 30 patients, grade 1, 2, 3 and 4 liver siderosis was present in 1, 3, 9 and 17 patients respectively. Serum ferritin level of patients with grade 4 siderosis was significantly higher (p = 0.03) compared to grade 3 cases. Pearson’s correlation coefficient test revealed significant positive correlation between grades of liver siderosis and amount of blood transfusion received (0.626, p < 0.01).

Conclusion: Grade of liver siderosis is associated with increased units of blood transfusion and is a good indicator for transfusional iron overload in beta-thalassaemia major patients.
