Health outcomes of international HIV-infected adoptees in the US

Background: International adoption of HIV-infected children is becoming increasingly common. Their health has not yet been described. Methods: HIV-infected international adoptees or refugees in foster care aged 0-20 years followed at Seattle Children's Hospital or Children's Hospital Colorado between January 1, 2004 and May 31, 2013 were included. Parameters were collected through retrospective chart review of baseline (first 6 months at study site) and annual follow-up visits. Results: Africa (90%) was the primary region of origin for the 79 children who met inclusion criteria. Median follow-up was 3 years (range: 0-7). At baseline, acute malnutrition was uncommon (8%); however, stunting occurred in 32%. Most stunting resolved during the study period. The most common medical issues at baseline were dermatologic (Tinea and Molluscum contagiosum) and gastrointestinal (parasites and diarrhea). Almost half (48%) had either mental health issues or behavioral problems. Educational delays (50%) were also common. Upon adoption, only 1% was severely (CD4% < 15%) immunosuppressed. Fifty-nine (75%) were on antiretroviral therapy (ART); 45 of these (76%) had suppressed viral load (VL). Of 14 children on ART with detectable VL, 11 (79%) demonstrated nonnucleoside reverse transcriptase inhibitor resistance and 1 (7%) protease inhibitor resistance. Conclusions: In this cohort of HIV-infected international adoptees, severe immunosuppression was uncommon. Most medical issues were mild. Stunting was common at baseline but largely resolved. Mental health issues, behavioral problems, and educational delays were common. Most children were on ART at adoption and most of these showed suppressed VL. Nonnucleoside reverse transcriptase inhibitor mutations were present in most viremic children.
