Abstract
Objective: This study compared the safety and efficacy of Safacto versus xyntha in patients with severe hemophilia A. Methods: Thirty-three male patients with severe hemophilia A were randomly divided into two groups. Seventeen patients received Safacto and 16 patients received Xyntha for four consecutive times. The dosage of FVIII was 40-50 IU/kg for each injection. Plasma level of FVIII activity was evaluated before every injection, 15 minutes after the injection and one month after the start of the trial. The rate of factor VIII activity, pain and joint motion were also assessed before and after the treatment. Results: Plasma level of FVIII clotting activity in Safacto and Xyntha were 1.96+/-0.5 IU/dl and 1.63+/-0.5 IU/dl and increased to 88.84+/-25.2 IU/dl and 100.09+/-17.8 IU/dl, respectively (P<0.001). Pain score and range of motion improvement were 9.3+/-0.9 and 8.7+/-0.1 in Safacto (P=0.17); and 9.4+/-0.8 and 8.8+/-0.3 in Xyntha (P=0.35), respectively. No allergic or other unfavorable reactions was observed with either of the preparations. Conclusion: This study showed that Safacto has a favorable efficacy and safety profile.

Abstract
INTRODUCTION This study compared the efficacy of Aryoseven with Novoseven to control bleeding episodes in patients with hemophilia A with inhibitors. METHODS Sixty-six patients were randomized into 2 groups, with 4 consecutive block randomization. These groups received Aryoseven and Novoseven dosages of 90 to 120 mug/kg intravenously every 2 hours. RESULTS Median (interquartile range) level of factor VIII (FVIII) inhibitor in groups A and B was 15.0 and 19.0 Bethesda Unit (BU) preadministration. Bleeding onset in group A was 1246 +/- 1104 minutes and in group B was 2301 +/- 1693 minutes (P = .311). The Kavakli global response scores and treatment success rate was comparable in both the groups. The side effects in groups A (9.7%) and B (2.9%) were comparable. CONCLUSION Biosimilar recombinant activated FVII is found to be as effective as Novoseven in the treatment of acute joint bleeding in patients with hemophilia with inhibitors. Its usage will decrease the gaps in hemophilia.Copyright © The Author(s) 2014.

A Comparison Between Recombinant Activated Factor VII (Aryoseven) and Novoseven in Patients With Congenital Factor VII Deficiency

Abstract
In order to establish the efficacy and biosimilar nature of AryoSeven to NovoSeven in the treatment of congenital factor VII (FVII) deficiency, patients received either agent at 30 mug/kg, intravenously per week for 4 weeks, in a randomized fashion. The primary aim was to compare FVIIcoagulation activity (FVII:C), 20 minutes after recombinant activated FVII (rFVIIa) injection, in the 2 groups. A secondary measure was self-reported bleeding. The median interquartile baseline range of the plasma level of activated FVII (FVIIa) activity in the 2 groups was 1.6 (1.1-14.0) IU/dL and 5.0 (1.1-25.5) IU/dL. All patients achieved levels of FVIIa (FVII:C) >30 IU/dL, 20 minutes after the injection of rFVIIa. Bleeding was similar between the 2 groups, with a comparable decrease in severity and frequency compared to the last month prior to treatment. AryoSeven is similar to NovoSeven in increasing postinjection FVIIa activity as well as in clinical safety and efficacy. Copyright © The Author(s) 2014.

Abstract
OBJECTIVE Thalassemia is one of the most common genetic disorders worldwide. Chronic blood transfusions treat the underlying anemia but may lead to iron toxicity. Effective iron chelation remains one of the main targets of clinical management of thalassemia major. In this study, iron-chelating activity of silymarin, a flavonolignan isolated from silybum marianum, was examined in beta-thalassemia major. METHODS Patients were treated with the combination of desferrioxamine and silymarin (Legalon; n = 49) or desferrioxamine plus placebo (n = 48) for 9 months. The serum levels of ferritin, iron, total iron-binding capacity (TIBC), soluble transferrin receptor, and hepcidin were determined at the baseline and after 9-month therapy. Liver function test was performed before and after treatment in both groups. RESULTS Serum ferritin levels decreased significantly from the beginning to the end of silymarin treatment (3028.8 +/- 2002.6 vs. 1972.2 +/- 1250.6 ng/mL); however, no significant change in serum ferritin was observed in the patients receiving placebo (2249.0 +/- 1304.2 vs. 2015.6 +/- 1146.8). Moreover, serum iron and TIBC levels were significantly reduced in silymarin group compared with placebo. Patients on silymarin therapy also exhibited a significant decrease in serum levels of hepcidin and soluble transferrin receptor after 9-month treatment period. A significant improvement in liver function test was observed in silymarin group in comparison with placebo. CONCLUSION This study shows that silymarin is effective at reducing iron overload in patients when used in conjunction with desferrioxamine. Therapeutic effects of silymarin on a background of desferrioxamine suggest the potential effectiveness of silymarin alone in reducing body iron burden. 2012 John Wiley & Sons A/S.
