Engagement in care among youth living with parenterally-acquired HIV infection in Romania.

Transition from adolescent to adult care can be challenging for youth living with HIV. We conducted a cohort study of youth born between 1985 and 1993 and infected with HIV parenterally, followed by the same medical team from age 15 years or first clinic visit until age 25 years or 30 November 2016. A longitudinal continuum-of-care was constructed, categorizing individuals' status for each month of follow-up as: engaged in care (EIC); not in care (NIC: no clinic visits within past year); lost-to-follow-up (LTFU: NIC and did not return to clinic); or died. Five hundred and forty-five individuals (52% male) were followed for 4775 person-years. At age 15, 92% were EIC, decreasing to 84% at age 20 and 74% at age 25. Of those EIC, HIV outcomes improved with age: 79% and 52% had a CD4 >= 200 cells/mu l and VL <400 cps/ml at age 15; increasing to 86% and 73% at age 20 and 87% and 80% at age 25. We conclude that youth infected during early childhood tended to disengage from care, even when followed by the same medical team for a lengthy period of time. For those that did engage in care, HIV-related outcomes improved from adolescence through adulthood.
