Bridging the gap between adult and paediatric outcomes in HIV-1 vertically infected children: a single-centre comparison with adult data.

Prognosis of HIV-1 infection dramatically improved during the last decade. Meanwhile, treatment-induced virological success has always been different in adult and children patients.To compare 10 years of follow up in HIV-1 vertically infected children and adult patients.Monocentric retrospective longitudinal analysis of vertically HIV-1-infected children and adult patients followed in the Nice University Hospital between 1999 and 2008. Immunological, virological and antiretroviral treatment data were recorded.Forty children and 1752 adult patients were included. Between 1996 and 2008, the percentage of children receiving HAART increased from 3.2% to 91%. Mean CD4% in the paediatric group remained stable between 29 +/- 8.1% in 1998 and 30 +/- 9.4% in 2008. Mean adult CD4-cell count significantly increased from 410 in 1998 to 556 cells/mL in 2008. Logistic regression analysis showed that the children-to-adult difference for indetectability (HIV PCR-RNA below 400 copies/mL) was significant (p < 0.0001) with an odds ratio of 0.61 (CI(95th): 0.52-0.72). Year-to-patient interaction was also significant with a decreasing divergence over time (p: 0.038).Nowadays as in adult patients, the control of HIV-1 replication is achieved in nearly eight of 10 children and the percentage of patients with severe immunodeficiency dramatically decreased compared with the mid 1990s.
