title: [Efficacy of antiviral therapy in patients with hemophilia and hepatitis C virus infection].
abstract: BACKGROUND
  HCV infection was common cause of morbidity and mortality in patients with hemophilia before 1986. We wanted to investigate the effect of treatment with combination therapy in HCV positive patients with hemophilia.
  
  
  METHODS
  The research included totally 13 persons afflicted with hemophilia and HCV infection out of 21 tested. The patients were submitted to laboratory and clinical tests as well as genotypization, whereby a different hepatitis C virus genetic adherence was observed. Parallel with this subcategory the other one was put into comparison, consisting of 12 patients afflicted with chronic C hepatitis, marked as non-hemophilics. The both subcategories were treated with combination antiviral therapy (peginterferon alpha-2a and ribavirin) during 48 weeks for genotype 1 and 4, in reference to 24 weeks for genotype 2 and 3. Within the treatment, clinical and laboratory side-effects were noticed, which did not require therapy interruption. A more frequent hemorrhage during the therapy was found within the hemophilics, rather than before initiliazing it.
  
  
  RESULTS
  After the statistical processing of the results (Students' t-test), statistically significant difference among these two subcategories was noticed as values for ALT (***p<0.0001) after 24 weeks of therapy, red blood cells (*p<0.05), haemoglobin and haematocrite (***p<0.0001) 24 weeks after therapy completing By PCR examination of the patients, 6 months after the end of treatment, a sustained viral response (SVR) of the same percentage was registrated within both subcategories, which is even greater than what the other authors have described.
  
  
  CONCLUSIONS
  Main results were without important difference between two subgroups, except for higher number of spontanuous bleeding in group with hemophilia, which was somewhat expected. Most importantly, we didn't find any difference in SVR rates between groups.
  
  
  CONCLUSIONS
  HCV positive patients with hemophilia could be successfully treated with combination therapy of peginterferon alfa-2a and ribavirin.
