The Effectiveness of Sofosbuvir and Daclatasvir in the Treatment of Hepatitis C in Thalassaemia Major Patients and their Effect on Haematological Factors

Context: Patients with thalassaemia arc at risk of infections such as hepatitis C virus (HCV) due to their repeated blood transfusions; meanwhile, the treatment of thalassaemia patients who had developed HCV infection is a controversial issue. Aims: Although the effectiveness of direct-acting anti virals on HCV infection has been confirmed, their side-effects as well as effects on haematological factors due to the resultant need for blood transfusion remain to be further understood. Materials and Methods: In this study, 61 patients with major beta thalassaemia and HCV infection, and who had a history of interferon treatment failure were examined. The patients underwent a 24-week treatment with sofosbuvir (SOF) and daclatasvir (DAC). Sustained virological response 12 was used to assess response to treatment. At the end of the study, the need for blood transfusion and serum terrain was evaluated. Results: About 98.4% of the patients responded to the treatment, and only one patient with genotype 1b did not respond positively. No significant complications necessitating treatment cessation were observed, and all the patients tolerated the treatment well. The level of liver enzymes showed a significant reduction 12 weeks after the treatment. The need for blood transfusions in patients before treatment was averagely 1.595 +/- 0.65 bag per month, in which 1.593 +/- 0.64 bags were received after treatment (P = 0.9). This regimen did not affect the amount of anaemia in patients and did not differentiate the need for blood transfusions. The rate of haemoglobin before treatment was 9.5 +/- 1.42 g/dl, which reached 9.6 +/- 1.6 g/dl after treatment (P = 0.54). Ferritin levels decreased significantly (from 1948.08 +/- 1539.54 to 1315.73 +/- 1207.67 ng/ml) (P = 0.001) in the patients after the treatment. Conclusion: Combination of SOF and DAC is an effective and tolerable treatment regimen without affect on the amount of anaemia in patients and did not differentiate the need for blood transfusions.
