title: Characteristics and prospects for hepatitis C therapy of an HIV-HCV coinfected population followed at a reference HIV center.
abstract: OBJECTIVE
  A cross-sectional study was performed during 2004 at a large HIV clinic in Spain to identify HIV-HCV coinfected individuals who might be candidates for HCV therapy.
  
  
  METHODS
  Plasma HCV RNA levels were measured in 405 anti-HCV antibody positive patients. Spontaneous HCV clearance had occurred in 11.4%. Overall, 165 (40.1%) of HCV-HIV coinfected patients had already been exposed to interferon (IFN)-based therapies. Excluding those currently on treatment, the majority of them had either failed (64/142; 45.1%) or not completed therapy (25/142; 17.6%). Other 103 (25.4%) chronic HCV carriers refused treatment or were not considered as appropriate candidates, most often due to low CD4 counts or severe neuropsychiatric conditions. Treatment was deemed feasible and planned in the near future in 91 (22.5%) patients. Unfavorable HCV genotypes (1 and 4) were significantly more frequent in this group of individuals ready for HCV treatment compared to those who had cleared HCV in the past following IFN-based therapies.
  
  
  RESULTS
  Spontaneous clearance of the HCV infection was low in HIV-coinfected patients. One third of our HIV-HCV coinfected population had already been exposed to HCV therapy, but only a minority had achieved sustained HCV clearance. Half of patients with active HCV replication never exposed to IFN were not considered as appropriate candidates for HCV therapy.
  
  
  CONCLUSIONS
  More flexible criteria would considerably increase the number of patients to be treated with IFN-based therapy. The majority of patients ready to initiate HCV therapy have a poor therapeutic profile.
