IAS 2013: HIV/HCV Coinfected Children in Europe Have Poor Hepatitis C Treatment Outcomes


HIV/HCV coinfection was uncommon among children and adolescents in a large European cohort, but within this group hepatitis C treatment generally occurred late and rarely led to sustained response, researchers reported at the 7th International AIDS Society Conference on HIV Pathogenesis, Treatment and Prevention (IAS 2013) this month in Kuala Lumpur.

HIV positive people with hepatitis C virus (HCV) coinfection generally experience more rapid liver disease progression and respond less well to interferon-based therapy than those with HCV alone. Coinfection among children, however, has been little studied and is not well understood.

Anna Turkova from the PENTA Foundation in Padua, Italy, and colleagues retrospectively evaluated the use and effectiveness of hepatitis C treatment for coinfected children and young people, age 25 and younger, in the Europe Pregnancy and Paediatric HIV Cohort Collaboration (EPPICC).

The researchers identified 10 coinfected children and adolescents (4 boys and 6 girls), from 4 of the 10 included cohorts. All were infected perinatally or during early childhood. Most (80%) had HCV genotype 1, with the remaining 2 having genotype 4 and unknown genotype. The patients had been infected with HCV for a median of about 13 years, and the median age was 17 at the start of hepatitis C treatment (range 10 to 21 years).

The children had relatively advanced HIV disease in the past, with a nadir (lowest-ever) CD4 T-cell count of 194 cells/mm3, but when they started hepatitis C treatment the median level was high, at 584 cells/mm3. All were on antiretroviral therapy (ART) along with hepatitis C treatment and two-thirds had undetectable HIV RNA.


"There is a very limited experience of treating HCV in HIV/HCV coinfected children," the researchers concluded. "Our results show poor treatment outcomes in these cases, most of whom had advanced fibrosis and genotype 1."
