[Chronic hepatitis C in patients with HIV/HCV coinfection with high CD4+ lymphocytes count].

AIM

analysis of data characterizing HCV infection in patients infected with HIV.

MATERIAL AND METHODS

37 persons (29 male and 8 female) aged 23-49 years (mediana 34), with HIV/HCV coinfection, treated (n=25) and untreated (n=12) with antiretroviral therapy. HAART was effective in treated patients; CD4+ count >350 cells/microl. Viral load of HIV and HCV, HCV genotypes, CD4/CD8, biochemical tests, histopathological examination were measured. Results were analyzed statistically.

RESULTS

the majority of patients were former IVDUs (n=31.84%), 3 persons (8%)--MSM, 3 (8%)--route of infection unknown. Duration of HCV infection 1-10 years, mediana 5. All patients were in A1 or A2 stage of HIV infection. Among patients treated with HAART (n=25) mediana of CD4+ count before treatment was 263 (69-595) cells/micro, mediana of HIV viral load 75000 copies/ml (n=7); 2040-263414 copies/ml. 17 patients were currently treated with PI, 17 with NNRTI, and 2 patients with NRTI only. HCV genotype was determined in 32 patients: 3a--n=19 (59%), 1--n= 9 (28%) 4--n=4 (13%). HCV viral load: 2.4 x 10(5)-7.73 x 10(6) IU/ml, mediana 1.6 x 10(6). Levels of ALT: 21-358 IU/ml, mediana 102, AST: 20-195 IU/ml, mediana 62, GGTP--9-463 IU/ml, mediana 58. ALT level was significantly higher in HCV genotype 3a infection (p=0.0214). Fibrosis stage above 2 was revealed in 3 patients and in majority (62%) was below 2. None patient had liver cirrhosis. Fibrosis was significantly higher in patients with low CD4+ nadir (p=0.03).

CONCLUSIONS

Progression of liver fibrosis is slow in patients coinfected with HIV/HCV with high CD4+ count. High percentage of HCV genotype 3 and mild fibrosis are good prognostic factors for effectiveness of HCV infection treatment in HIV infected persons.
