null Infectious Diseases Unit
Hospital Universitario Reina Sofía (Córdoba)


The Infectious Diseases Unit at the Reina Sofía University Hospital in Cordoba is under the leadership of Antonio Rivero Román. Our research group studies infection diseases using two main approaches:

  • Clinical and epidemiological studies (including clinical trials). Our objective in these studies is to identify and differentiate risk factors, clinical features and the efficacy/safety of new treatments in order to improve the prognosis of infectious diseases.
  • Pathogenesis studies for use in developing specific clinical strategies. The most relevant are our studies on immunopathology.

All our studies start by identifying a clinical problem, which we try to solve using an experimental approach. Our aim is for our scientific findings to have an impact on healthcare solutions and to improve disease prognosis (translational research).

Our specific lines of research are as follows:

  1. HIV infection: Our lines of research concerning the natural history of HIV infection include
    • Fatty liver disease in HIV-infected patients
    • Resistance to HIV infection
    • Innate immunity against HIV
    • The evaluation of new therapeutic regimens for the treatment of HIV infection
  2. HIV and coinfection with hepatotropic viruses: The research in this section encompass 8 main lines:
    • Epidemiology of HIV-HCV co-infection in Andalusia
    • Epidemiology of HEV infection in HIV-infected patients
    • Evaluation of routes of HEV transmission in HIV-infected patients
    • The natural history of fibrosis/cirrhosis of the liver in HCV-infected patients
    • Clinical implications and complications of HEV infection in HIV-infected patients
    • Evaluation of new therapeutic regimens for the treatment of HCV infection in HIV coinfected patients
    • Optimization of HCV treatment in patients co-infected with HIV
    • Prediction of response to HCV treatment
