title: [Prevalence of hepatitis C virus among HIV-infected patients in Area 2 of Madrid].
abstract: BACKGROUND
  The evolution of HIV infection, a rapid and fatal illness not long time ago, has become a chronic disease due to the implementation of new antiretroviral treatment. Therefore it is essential to focus on the management of concurrent illnesses such as chronic hepatitis C infection, specially as they share common routes of transmission.
  
  
  METHODS
  A cross sectional survey was done to determine the prevalence of HIV and HCV coinfection, measuring different HIV and HCV variables among 651 HIV infected patients of a health area in Madrid.
  
  
  RESULTS
  500 patients (76.8%) were male and 151 female (23%). HCV serology was performed in all the patients and resulted positive in 45.7% (298) most of them drug users (84.8%). The CD4 cell count was lower in patients HIV-HCV coinfected compared to those HCV negative (p < 0.001).
  
  
  CONCLUSIONS
  This study shows a high prevalence of HIV-HCV coinfection, mainly due to parenteral transmission. We emphasize the low percentage of coinfected patients treated with interferon and ribavirine which probably will increase in the future.
