Background In human immunodeficiency virus (HIV)–positive adults, low CD4 cell counts despite fully suppressed HIV-1 RNA on antiretroviral therapy (ART) have been associated with increased risk of morbidity and mortality. We assessed the prevalence and outcomes of poor immune response (PIR) in children receiving suppressive ART. Methods Sixteen cohorts from the European Pregnancy and Paediatric HIV Cohort Collaboration (EPPICC) contributed data. Children <18 years at ART initiation, with sustained viral suppression (VS) (≤400 copies/mL) for ≥1 year were included. The prevalence of PIR (defined as World Health Organization advanced/severe immunosuppression for age) at 1 year of VS was described. Factors associated with PIR were assessed using logistic regression. Rates of acquired immunodeficiency syndrome (AIDS) or death on suppressive ART were calculated by PIR status. Results Of 2318 children included, median age was 6.4 years and 68% had advanced/severe immunosuppression at ART initiation. At 1 year of VS, 12% had PIR. In multivariable analysis, PIR was associated with older age and worse immunological stage at ART start, hepatitis B coinfection, and residing in Thailand (all P ≤ .03). Rates of AIDS/death (95% confidence interval) per 100 000 person-years were 1052 (547, 2022) among PIR versus 261 (166, 409) among immune responders; rate ratio of 4.04 (1.83, 8.92; P < .001). Conclusions One in eight children in our cohort experienced PIR despite sustained VS. While the overall rate of AIDS/death was low, children with PIR had a 4-fold increase in risk of event as compared with immune responders.

Although improving health outcomes in human immunodeficiency virus (HIV)-infected persons has been identified as a national priority, little is known about the factors associated with hospitalizations of HIV-infected persons in the highly active antiretroviral therapy (HAART) era. Since the introduction of HAART in 1996, there has been a dramatic increase in the life expectancy of HIV-infected persons. However, aging and the long term use of HIV medications have led to an increased incidence of chronic, non-HIV-related illnesses. To improve patient outcomes, the factors that contribute to co-morbidities in HIV-infected persons need to be identified. As a first step, we will summarize the current literature on causes and contributing factors of hospitalizations in adults infected with HIV in the HAART era.

Objectives: To assess the effect of migrant status on treatment outcomes among children living with HIV in Europe.Methods: Children aged < 18 years at the start of antiretroviral therapy (ART) in European paediatric HIV observational cohorts where ≥ 5% of children were migrants (defined as born abroad) were included. Three outcomes were considered: (i) severe immunosuppression-for-age; (ii) viraemic viral load (≥ 400 copies/ mL) at 1 year after ART initiation; and (iii) AIDS/death after ART initiation. The effect of migrant status was assessed using univariable and multivariable logistic and Cox models.Results: Of 2620 children included across 12 European countries, 56% were migrants. At ART initiation, migrant children were older than domestic-born children (median 6.1 vs. 0.9 years, p < 0.001), with slightly higher proportions being severely immunocompromised (35% vs. 33%) and with active tuberculosis (2% vs. 1%), but a lower proportion with an AIDS diagnosis (14% vs. 19%) (all p < 0.001). At 1 year after beginning ART, a lower proportion of migrant children were viraemic (18% vs. 24%) but there was no difference in multivariable analysis (p = 0.702), and no difference in severe immunosuppression (p = 0.409).However, there was a trend towards higher risk of AIDS/death in migrant children (adjusted hazard ratio = 1.51, 95% confidence interval: 0.96-2.38, p = 0.072). Conclusions:After adjusting for characteristics at ART initiation, migrant children have virological and immunological outcomes at 1 year of ART that are comparable to those who are domestic-born, possibly indicating equity in access to healthcare in Europe. However, there was some evidence of a difference in AIDS-free survival, which warrants further monitoring.

The U.S. Marshals Service (USMS) prisoner population is diverse and includes immigration violators, fugitives that have evaded apprehension, perpetrators of Medicaid fraud, and parole and probation violators. Unlike state and local jails, the USMS has numerous housing options for its prisoners. Given the unique characteristics, federal prisoners' quality of care, and subsequent clinical outcomes, may differ from those of state and local inmates. However, little is known about hospitalization rates and length of stay for HIV-positive USMS prisoners. The purpose of this study is to examine hospitalizations among HIV-infected prisoners in the custody of the USMS.
