Risk factors for delayed viral suppression on first-line antiretroviral therapy among persons living with HIV in Haiti, 2013-2017.

Studies of viral suppression on first-line antiretroviral therapy (ART) in persons living with human immunodeficiency virus (PLHIV) in Haiti are limited, particularly among PLHIV outside of the Ouest department, where the capital Port-au-Prince is located. This study described the prevalence and risk factors for delayed viral suppression among PLHIV in all geographic departments of Haiti between 2013 and 2017. Individuals who received viral load testing 3 to 12 months after ART initiation were included. Data on demographics and clinical care were obtained from the Haitian Active Longitudinal Tracking of HIV database. Multivariable logistic regression was performed to predict delayed viral suppression, defined as a viral load ≥1000 HIV-1 RNA copies/mL after at least 3 months on ART. Viral load test results were available for 3,368 PLHIV newly-initiated on ART. Prevalence of delayed viral suppression was 40%, which is slightly higher than previous estimates in Haiti. In the multivariable analysis, delayed viral suppression was significantly associated with younger age, receiving of care in the Ouest department, treatment with lamivudine (3TC), zidovudine (AZT), and nevirapine (NVP) combined ART regimen, and CD4 counts below 200 cells/mm3. In conclusion, this study was the first to describe and compare differences in delayed viral suppression among PLHIV by geographic department in Haiti. We identified populations to whom public health interventions, such as more frequent viral load testing, drug resistance testing, and ART adherence counseling should be targeted.

Demographic, clinical, and virologic characteristics of African-born persons with HIV/AIDS in a Minnesota hospital.

Minnesota is currently home to the tenth largest African population and the second largest East African population in the United States. HIV is increasingly being diagnosed in African-born persons in Minnesota. A retrospective survey was conducted on all African-born patients in our HIV clinic between January 1994 and June 2005. We identified 237 patients who were African-born and HIV-positive. They constituted 12% of patients attending the clinic within the study timeframe. There was no significant difference in the ages of the African-born and non-African patients in the HIV clinic. African-born patients were more likely to be women compared with non-African patients (p < 0.001). Forty-three percent of the African-born patients presented with AIDS as defined by CD4(+) T cell counts less than 200 cells per milliliter compared to 33% of antiretroviral naïve non-African HIV patients in the clinic (p < 0.001). Most patients were infected through heterosexual contact and only 4% were diagnosed as a result of routine testing. Seven known HIV subtypes and four unique recombinant forms were identified. The most common opportunistic infection was pulmonary tuberculosis. African immigrants with HIV appear to: (1) access care at later stages of HIV disease than other patients in our clinic; (2) are often infected with non-B subtypes; (3) do not routinely get tested for HIV. Increased awareness to this growing trend is needed for health care providers and public health officials to tailor educational programs and prevention efforts for African immigrants in the United States.

HIV/AIDS and associated conditions among HIV-infected refugees in Minnesota, 2000­2007.

In 2010, the requirement for human immunodeficiency virus (HIV) testing of adult refugees prior to US resettlement was removed, thus leading to a potential for missed diagnosis. We reviewed refugee health assessment data and medical charts to evaluate the health status of HIV-infected refugees who arrived in Minnesota during 2000-2007, prior to this 2010 policy change. Among 19,292 resettled adults, 174 were HIV-infected; 169 (97%) were African (median age 26.4 (range: 17-76) years). Charts were abstracted for 157 (124 (79%) with ≥ 1 year of follow-up). At initial presentation, two of 74 (3%) women were pregnant; 27% became pregnant during follow-up. HIV clinical stage varied (59%, asymptomatic; 11%, mild symptoms; 10%, advanced symptoms; 3%, severe symptoms; 17%, unknown); coinfections were common (51 tuberculosis, 13 hepatitis B, 13 parasites, four syphilis). Prior to arrival 4% had received antiretrovirals. Opportunistic infections were diagnosed among 13%; 2% died from AIDS-related causes. Arrival screening may be needed to identify these HIV-infected refugees and prevent HIV-related morbidity and mortality.
