Response to direct-acting antivirals for hepatitis C treatment in vertically HIV/HCV co-infected patients.

Direct-acting antivirals (DAAs) for HCV treatment have improved tolerance and efficacy among adults, but experience in vertical transmission is scarce. In our vertically HIV/HCV co-infected youth cohort of 58 patients, DAA achieved excellent rates of cure among naïve and pretreated individuals. Treating vertically infected seems important as 29.6% displayed advanced fibrosis at treatment initiation.

Longitudinal evolution of vertically HIV/HCV-co-infected vs HCV-mono-infected children.

HIV co-infection has been suggested to play a deleterious role on the pathogenesis of liver fibrosis among vertically HCV-infected children. The aim of this study was to describe the longitudinal evolution of vertically acquired HIV/HCV co-infection in youths, in comparison with HCV infection alone. This was a retrospective, multicentre study including vertically HIV/HCV-co-infected patients and age- and sex-matched vertically HCV-mono-infected patients. Progression to advanced liver fibrosis, defined as F3 or more by elastography or METAVIR biopsy staging, and response to treatment were compared by means of univariate and multivariate regression analyses and Cox regression models. Sixty-seven co-infected patients were compared with 67 matched HCV-mono-infected patients. No progression to advanced liver disease was observed during the first decade. At a median age of 20.0 [19.0, 22.0] years, 26.7% co-infected vs 20% mono-infected had progressed to advanced fibrosis (P = .617). Peg-IFN/RBV for HCV treatment was given to 37.9% vs 86.6% (P-value < .001). At treatment initiation, co-infected patients were older (16.9 ± 4.1 vs 11.7 ± 4.5 years, P < .001), and 47.1% vs 7.1% showed advanced fibrosis (P < .003), with no differences in hard-to-treat genotype distribution. Sustained viral response was comparable between groups (43.5% vs 44.0%, P = .122). In vertically HIV/HCV-co-infected patients, the progression to liver fibrosis was rare during childhood. At the end of adolescence, over 25% of patients displayed advanced liver disease. Response to Peg-IFN/RBV was poor and comparable in both groups, supporting the need for fast access to early treatment with direct-acting antivirals against HCV for vertically co-infected patients.

Effect of Hepatitis C Virus Coinfection on the Progression of Vertically Acquired Human Immunodeficiency Virus Infection During Childhood and Adolescence.

Data for a total of 57 patients vertically coinfected with human immunodeficiency virus (HIV)/hepatitis C virus (HCV) and 365 HIV-monoinfected patients were compared until their transition to adult care. No differences regarding the dynamics of CD4 and/or CD8 T-cell counts during childhood were found. The coexistence of HCV does not increase the risk of disease progression in vertically HIV-infected patients.
