ABSTRACT
Context: Patients with thalassaemia are 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 antivirals 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 ferritin 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.
ABSTRACT
Background & objectives: Fatty acids may affect the expression of genes, and this process is influenced by sex hormones. Cytokines are involved in the pathogenesis of non-alcoholic fatty liver disease (NAFLD), so this study was aimed to assess the association of erythrocyte membrane fatty acids with three cytokines and markers of hepatic injury in NAFLD patients and to explore whether these associations were the same in both sexes. Methods: In this cross-sectional study, 62 consecutive patients (32 men and 30 women) with NAFLD during the study period. Tumour necrosis factor-? (TNF-?), interleukin 6 (IL-6), monocyte chemoattractant protein-1 (MCP-1), aspartate aminotransferase and alanine aminotransferase were measured in a fasting serum sample, and Fibroscan was conducted for each individual. Gas chromatography was used to measure erythrocyte membrane fatty acids. Univariate and multiple linear regressions were used to analyze data. Results: In men, IL-6 had a significant (P <0.05) positive association with total ?-3 polyunsaturated fatty acids (PUFAs). In women, TNF-? had a significant positive association with total ?-3 (P <0.05) and ?-6 (P <0.01) PUFAs, IL-6 had a significant (P <0.05) positive association with total monounsaturated fatty acids and MCP-1 had a significant positive association with total trans-fatty acids (P <0.05). No significant associations were observed between erythrocyte membrane fatty acids and liver enzymes or Fibroscan report in both sexes. In this study, women were significantly older than men [51 (42.75-55) vs 35.5 (29-52), P <0.01], so the associations were adjusted for age and other confounders. Interpretation & conclusions: Erythrocyte membrane fatty acid profile was not associated with serum liver enzymes or Fibroscan reports in NAFLD patients, but it had significant associations with serum TNF-?, IL-6 and MCP-1 and these associations were probably sex dependent.
