Virologic, immunologic and clinical responses in foreign-born versus US-born HIV-1 infected adults initiating antiretroviral therapy: an observational cohort study

Evaluation of Undiagnosed HIV Estimates Computed from the CD4 Depletion Model in a Rural, Medium-low HIV Prevalence State

The CD4 depletion model estimates diagnosis delays by approximating infection date from CD4 T-cell count at diagnosis, and back-calculation can compute the proportion of undiagnosed PLWHA. The model assumes the immigration of PLWHA to the U.S. is negligible and counts as a transmission event, which may be impractical outside high prevalence states. Duration of U.S. residency among foreign-born PLWHA and diagnosis delays were compared. The impact on estimates of undiagnosed PLWHA was tested through simulation with different proportions of foreign-born people assumed to have acquired HIV abroad. In 67% of foreign-born people, the mean (SD) years of delay (9.9 (6.3)) exceeded the duration of U.S. residency (2.0 (1.9)). Additionally, inaccuracies in the estimates for proportions of undiagnosed PLWHA were pronounced when foreign-born people who acquired HIV abroad comprised 30% of diagnoses. The CD4 model inadvertently misclassified some diagnoses as in-state transmission events. Consequently, simulated results demonstrated inaccuracies and unstable calculations.

Comparison of HIV Viral Suppression Between a Sample of Foreign-Born and U.S.-Born Women of Color in the United States

We investigate the association between nativity status (U.S.- vs foreignborn) and viral suppression among women of color (WOC) with HIV (HIV +) and whether this association was modified by education and housing.

METHODS

Data were from 549 HIV + WOC, who participated in the Health Resources and Services Administration-funded WOC Initiative 2009-2013. We used generalized estimating equation models to quantify the association between the respondents' nativity status and viral suppression.

RESULTS

After adjusting for covariates, foreign-born WOC were 2.2 times (95% confidence interval: 1.25, 3.85) more likely to achieve viral suppression than U.S.-born WOC. This association was not modified by education or housing status.

CONCLUSIONS

Despite facing barriers to care, foreign-born WOC were more likely to achieve viral suppression than U.S.-born WOC. Programs aiming to end the HIV epidemic and reduce HIV disparities in the U.S. should consider these findings as they provide a more nuanced understanding of HIV + WOC.

Factors Associated with Viral Suppression Among Racial/Ethnic Minority Women in the Miami-Dade County Ryan White Program, 2017

The study's objective was to identify factors associated with differences in the rate of viral suppression among minority women with HIV/AIDS in care in the Miami-Dade County Ryan White Program (RWP). A retrospective cohort study was conducted using social characteristics and laboratory data of minority women enrolled in the Miami-Dade County RWP in 2017. Viral suppression was defined as <200 copies/mL using the last viral load test of 2017. Multilevel logistic regression models were used to estimate adjusted odds ratio (aOR) and 95% confidence intervals (CIs). Of the 1,550 racial/ethnic minority women in the study population, 43.1% were African American, 31.3% were Hispanic, and 25.6% were Haitian. The proportion of women virally suppressed was lower among African Americans (80.8%) than among Hispanics (86.4%) and Haitians (85.1%). Viral suppression rates were significantly lower among women aged 18-34 years (aOR: 0.41, CI: 0.27-0.64) and 35-49 years (0.63, 0.45-0.90) vs. ≥50 years, born in the United States (0.48, 0.30-0.78), having a household income of <100% the federal poverty level (0.54, 0.30-0.95), previously diagnosed with AIDS (0.60, 0.44-0.81), reporting problematic drug use (0.23, 0.08-0.69), and living in a residentially unstable neighborhood (0.77, 0.64-0.93). Race/ethnicity was not associated with viral suppression after adjusting for other factors. Factors associated with lack of viral suppression were similar among minority racial/ethnic groups. Interventions at the individual level focusing on young, U.S. born individuals, and those who report drug use, and at the neighborhood level for those living in residentially unstable neighborhoods are needed to improve viral suppression outcomes.

Antiretroviral Therapy and Viral Suppression Among Foreign-Born HIV-Infected Persons Receiving Medical Care in the United States: A Complex Sample, Cross-Sectional Survey

Immigrants to the United States are more likely to be diagnosed with human immunodeficiency virus (HIV) infection compared with native-born persons. Navigating access to healthcare in the United States can be challenging for foreign-born persons, and HIV treatment outcomes may be suboptimal for these persons. We compared characteristics of and assessed disparities in clinical outcomes of foreign-born persons in care for HIV in the United States. The Medical Monitoring Project is a complex sample, cross-sectional survey designed to be nationally representative of HIV-infected adults receiving medical care in the United States. Using data from 2009, 2010, and 2011, we conducted descriptive analyses and multivariable logistic regression to assess associations between foreign-born status and antiretroviral therapy (ART) prescription, and between foreign-born status and viral suppression. In all, 13.4% of HIV-infected persons were self-identified as foreign-born; the most common regions of birth were Central America and Mexico (45.4%) and the Caribbean (16.0%). Nearly 90% of foreign-born persons were diagnosed with HIV after entry into the United States. Compared with US-born persons, foreign-born persons were more likely to be younger, Hispanic, less educated, and uninsured. The prevalence of ART prescription (prevalence ratio 1.00; 95% confidence interval 0.98-1.02) was not significantly different between foreign-born and US-born persons. A higher percentage of foreign-born persons achieved viral suppression compared with US-born persons (prevalence ratio 1.05; 95% confidence interval 1.00-1.09). No major disparities in ART prescription and viral suppression were found between foreign-born and US-born HIV-infected persons receiving medical care, despite higher percentages being uninsured.
