HIV testing and counselling for migrant populations living in high-income countries: a systematic review.

BACKGROUND: The barriers to HIV testing and counselling that migrants encounter can jeopardize proactive HIV testing that relies on the fact that HIV testing must be linked to care. We analyse available evidence on HIV testing and counselling strategies targeting migrants and ethnic minorities in high-income countries. METHODS: Systematic literature review of the five main databases of articles in English from Europe, North America and Australia between 2005 and 2009. RESULTS: Of 1034 abstracts, 37 articles were selected. Migrants, mainly from HIV-endemic countries, are at risk of HIV infection and its consequences. The HIV prevalence among migrants is higher than the general population's, and migrants have higher frequency of delayed HIV diagnosis. For migrants from countries with low HIV prevalence and for ethnic minorities, socio-economic vulnerability puts them at risk of acquiring HIV. Migrants have specific legal and administrative impediments to accessing HIV testing-in some countries, undocumented migrants are not entitled to health care-as well as cultural and linguistic barriers, racism and xenophobia. Migrants and ethnic minorities fear stigma from their communities, yet community acceptance is key for well-being. CONCLUSIONS: Migrants and ethnic minorities should be offered HIV testing, but the barriers highlighted in this review may deter programs from achieving the final goal, which is linking migrants and ethnic minorities to HIV clinical care under the public health perspective.

Chronicity, ageing and multimorbidity. / Cronicidad, envejecimiento y multimorbilidad.

Thanks to highly active antiretroviral therapy (HAART), HIV-related mortality has been drastically reduced and HIV infection has become a chronic disease. The HIV-infected population is ageing prematurely. Despite good immunovirological control, HIV causes chronic inflammation and accelerated immunosenes-cence. This clinically manifests as an increased prevalence of age-related comorbidity and frailty occurring earlier than in the general population. The heterogeneity of older HIV-infected adults highlights the rele-vance of identifying those who are at risk of poor health, and frailty may be an effective indicator. The rela-tionship between ageing, HIV infection, antiretroviral treatment, comorbidities and frailty still needs to be clarified. Elderly HIV-infected adults are complex patients who require a specific, global and multidisci-plinary approach.

HIV infection follow-up, organisational and management model. / Modelo de seguimiento, organización y gestión de la infección por VIH.

Thanks to advances in antiretroviral therapy, the life expectancy of people infected with HIV is approaching that of the general population. In this new clinical scenario, comorbidities related to age and geriatric syn-dromes are gaining prominence. The experiences from various innovative initiatives for the care of patients with chronic diseases indicate that the optimisation of health outcomes not only depends on proper diagnosis and treatment, but also on the way in which care is managed. To cover the future needs of HIV-infected patients, we will have to implement care models that have proven effective in other types of chronic di-seases. This will require a reliable method to stratify patients according to their level of complexity or functional capacity to detect the most vulnerable cases.

Primary prevention. / Prevención primaria.

HIV infection is still not controlled in Spain. New HIV infection prevention strategies are required, especially in populations of higher incidence, by means of combined interventions. Early diagnosis and treatment of HIV-infected individuals is the most cost-effective strategy to control the epidemic, including interventions designed to motivate behavioural changes. These types of campaigns must not only be directed to the general population through mass channels, but also to key populations through more specific channels and messages. Biomedical interventions like pre-exposure prophylaxis, uses a combination of biomedical tools to reduce the risk of HIV acquisition, and are usually accompanied of behavioural interventions. The influence of structural factors, social justice and defending the rights of people living with HIV have a significant impact on prevention strategies. Structural interventions are designed to influence these factors that make some individuals or populations more vulnerable to HIV infection.
