Abstract

Objectives: To define differences in liver histology between HIV/HCV coinfection and HCV monoinfection, and to investigate possible causative factors. Methods: Liver biopsies (LBs) from 440 consecutive HIV/HCV-coinfected patients (Group HIV/HCV) and 374 consecutive HCV-monoinfected patients (Group HCV) were evaluated for necroinflammation and fibrosis (Ishak) by a pathologist unaware of the clinical and laboratory data. All patients were HBsAg-negative, with no history of alcohol abuse and naïve to anti-HCV treatment. At LB, 78.4 % of patients in Group HIV/HCV were on an antiretroviral regimen. Results: HIV/HCV-coinfected patients compared to the HCV-monoinfected patients were younger (p <0.0001), more frequently males (p <0.0001), and had HCV genotype 3 (p <0.0001); they showed a good immunological condition (CD4+ cell count: 518 ± 166 cells/mm3). Patients in Group HIV/HCV more frequently showed a fibrosis score ≥4 (27.5 vs. 20.6 %, p <0.05) and a necroinflammation score ≥9 (25.9 vs. 13.4 %; p <0.0001). The prevalence of patients with fibrosis score ≥4 was significantly higher in older age classes in both Group HIV/HCV (p <0.005) and Group HCV (p <0.05). A necroinflammation score ≥9 was significantly higher in older age classes only in Group HIV/HCV (p <0.05). A multivariate analysis for Group HIV/HCV revealed that the patient age and nadir of CD4+ cell count were independently associated to higher degrees of fibrosis, the patient age and antiretroviral treatment were associated to higher degrees of necroinflammation, and HCV genotype 3 was associated to higher degrees of steatosis. Conclusion: The data suggest a need for early anti-HCV treatment in both HCV-monoinfected and HIV/HCV-coinfected patients.
