Coming and going: Some aspects of care for migrants with HIV in the UK

Late HIV diagnosis among migrant women living in Europe - a systematic review of barriers to HIV testing

Objectives

HIV transmission persists in Europe, with migrants accounting for over two-fifths of new diagnoses. Over half of all women in Europe are diagnosed late - particularly migrant women. Therefore, an updated understanding of migrant women's needs is crucial to inform inclusive and relevant HIV research, services, and policies.

Methods

A systematic review relating to factors influencing late HIV diagnoses among migrant women living in Europe in 2011-2021 was conducted, based on data from 12 papers relating to 13 European Union (EU) countries and three non-EU countries.

Results

The studies revealed a range of individual, sociocultural, and structural barriers to HIV diagnosis. Individual barriers included low perceived risk of HIV, lack of knowledge about HIV symptoms and HIV services, lack of trust in healthcare systems, and fear of societal implications of an HIV diagnosis. Sociocultural barriers included language and communication challenges, stigma, and lack of community testing opportunities. Structural factors included poverty, poor living conditions, unclear legal rights, administrative barriers to healthcare access, and lack of testing opportunities.

Conclusions

Barriers varied according to resident country, healthcare system, and country/region of origin. The studies highlighted the importance of inclusive research and service design and development, to address the needs of migrant women and reduce inequalities, especially given the current climate in Europe and the everchanging patterns of migration.

HIV Testing and Sexual Health Among Black African Men and Women in London, United Kingdom

Importance

Black African adults are disproportionately affected by HIV in the United Kingdom. Many within this population acquire HIV after migration or are diagnosed late. Data are needed to inform targeted interventions to increase HIV testing and prevention in this population.

Objective

To inform future HIV prevention strategies by estimating diagnosed and undiagnosed HIV infection and measuring changes in HIV testing rates in black African adults in London, United Kingdom.

Design, Setting, and Participants

This cross-sectional study used a self-completed survey conducted from September 20 to December 3, 2016. Questionnaires were linked to an optional, anonymous oral fluid HIV test and compared with data from a previous survey (2004). Respondents were recruited from social and commercial venues frequented by black African adults in London. Of 2531 individuals approached in 63 venues, 752 agreed to participate. Data were analyzed initially in March 2017 (as part of internal reporting) and again in August 2018.

Main Outcomes and Measures

Self-reported HIV testing within the past 5 years; diagnosed and undiagnosed HIV prevalence. Logistic regression examined factors associated with HIV testing by sex.

Results

In total, 292 women (median [interquartile range] age, 31 [25.0-41.5] years) and 312 men (median [interquartile range] age, 35 [25.0-41.5] years) were included in the analysis. More than half of men (159 [51.0%]) and women (154 [52.7%]) had been tested for HIV in the past 5 years. In multivariable analysis, HIV testing was associated with a range of factors in both sexes, including health service attendance, time in the United Kingdom, and sexually transmitted infection diagnosis. Increases in HIV testing in the past 5 years were observed between 2004 and 2016 for both sexes. In the 2016 sample, 219 of 235 women (93.2%) and 206 of 228 men (90.4%) tested HIV negative. Among those testing positive, 56.3% of women (9 of 16) and 40.9% of men (9 of 22) self-reported as HIV negative or untested, indicating they were living with undiagnosed HIV. A fifth of women (20.7%) and 25.0% of men reported condomless last sex with a partner of different or unknown HIV status in the past year.

Conclusions and Relevance

Despite efforts to increase HIV testing, uptake in black African communities in London remains modest. This study identified a large fraction of undiagnosed infection-greater than other at-risk populations-suggesting that the prevention and care needs of this group are not adequately met.

Factors Associated With Access to HIV Testing and Primary Care Among Migrants Living in Europe: Cross-Sectional Survey

Background

There is a heavy and disproportionate burden of human immunodeficiency virus (HIV) infection among migrant communities living in Europe. Despite this, the published evidence related to HIV testing, prevention, and treatment needs for migrants is sparse.

Objective

The aim of this study was to identify the factors associated with access to primary care and HIV testing among migrant groups living in Europe.

Methods

A Web-based survey (available in 14 languages) was open to all people aged 18 years and older, living outside their country of birth in the World Health Organization (WHO) European area. Community organizations in 9 countries promoted the survey to migrant groups, focusing on those at a higher risk of HIV (sub-Saharan Africans, Latin Americans, gay or bisexual men, and people who inject drugs). Multivariable analysis examined factors associated with access to primary care and previous history of an HIV test.

Results

In total, 559 women, 395 heterosexual men, and 674 gay or bisexual men were included in the analysis, and 68.1% (359/527) of women, 59.5% (220/371) of heterosexual men, and 89.6% (596/664) of gay or bisexual men had tested for HIV. Low perceived risk was the reason given for not testing by 62.3% (43/69) of gay or bisexual men and 83.3% (140/168) of women and heterosexual men who reported never having tested for HIV. Access to primary care was >60% in all groups. Access to primary care was strongly positively associated with living in Northern Europe compared with Southern Europe (women: adjusted odds ratio, aOR 34.56 [95% CI 11.58-101]; heterosexual men: aOR 6.93 [95% CI 2.49-19.35], and gay or bisexual men: aOR 2.53 [95% CI 1.23-5.19]), whereas those with temporary residency permits were less likely to have access to primary care (women: aOR 0.41 [95% CI 0.21-0.80] and heterosexual men: aOR 0.24 [95% CI 0.10-0.54] only). Women who had experience of forced sex (aOR 3.53 [95% CI 1.39-9.00]) or postmigration antenatal care (aOR 3.07 [95% CI 1.55-6.07]) were more likely to have tested for HIV as were heterosexual men who had access to primary care (aOR 3.13 [95% CI 1.58-6.13]) or reported “Good” health status (aOR 2.94 [95% CI 1.41-5.88]).

Conclusions

Access to primary care is limited by structural determinants such as immigration and health care policy, which varies across Europe. For those migrants who can access primary care and other health services, missed opportunities for HIV testing remain a barrier to earlier testing and diagnosis for migrants in Europe. Clinicians should be aware of these potential structural barriers to HIV testing as well as low perception of HIV risk in migrant groups.

Fear of deportation may limit legal immigrants' access to HIV/AIDS-related care: a survey of Swedish language school students in Northern Sweden

The increasing rates of HIV infection that are currently being reported in high-income countries can be partly explained by migration from countries with generalized epidemics. Yet, early diagnosis of HIV/AIDS in immigrants remains a challenge. This study investigated factors that might be limiting immigrants’ access to HIV/AIDS care. Data from 268 legal immigrant students of two Swedish language schools in Northern Sweden were analyzed using logistic regression. Thirty-seven percent reported reluctance to seek medical attention if they had HIV/AIDS. Fear of deportation emerged as the most important determinant of reluctance to seek care after adjusting for socio-demographic factors, knowledge level, stigmatizing attitudes and fear of disclosure. Targeted interventions should consider the heterogeneity of migrant communities and the complex interplay of various factors which may impede access to HIV-related services. The myth about deportation because of HIV/AIDS should be countered.

[HIV/AIDS care and international migrations in the rural district of Nanoro, Burkina Faso]

West African Countries account for almost half of the estimated 20 000 000 international migrants in the continent. In the frame of the scaling up of HAART, our study aims to identify specific features and constraints of access to care for HIV migrant patients returning to Burkina Faso. From January 2007 to August 2011, the Nanoro District Hospital, serving a rural area in the Centre-West of Burkina Faso, followed 437 HIV/AIDS adult patients. Migrants were 139/437 (31.8 %), of whom 108/139 (77.7 %), declared they returned to Burkina Faso to seek care, because the area they migrated to did not offer specific HIV health assistance. At baseline, 113/139 (81,3 %) migrants and 181/298 (60,7 %) residents were in WHO clinical stages III or IV (p< 0.01). For every 100 patients/ year under HAART, 25.5 migrants (91.4 % of whom to foreign countries) and 5.7 Burkina residents were transferred to other centers (p<0.01). 21.8 migrants and 8.5 residents were dead or lost to follow up (p<0.05). For migrant patients, access to HIV screening and care seems to be delayed. The high frequency of migrants under HAART working abroad requires an improved cooperation among the health systems of the African Countries.

Access to and utilisation of GP services among Burmese migrants in London: a cross-sectional descriptive study

Background

An estimated 10,000 Burmese migrants are currently living in London. No studies have been conducted on their access to health services. Furthermore, most studies on migrants in the United Kingdom (UK) have been conducted at the point of service provision, carrying the risk of selection bias. Our cross-sectional study explored access to and utilisation of General Practice (GP) services by Burmese migrants residing in London.

Methods

We used a mixed-method approach: a quantitative survey using self-administered questionnaires was complemented by qualitative in-depth interviews for developing the questionnaire and triangulating the findings of the survey. Overall, 137 questionnaires were received (a response rate of 57%) and 11 in-depth interviews conducted. The main outcome variables of the study included GP registration, barriers towards registration, GP consultations, barriers towards consultations, and knowledge on entitlements to health care. Quantitative data were analysed using descriptive statistics, association tests, and a multivariate analysis using logistic regression. The qualitative information was analysed using content analysis.

Results

The respondents were young, of roughly equal gender (51.5% female), well educated, and had a fair level of knowledge on health services in the UK. Although the GP registration rate was relatively high (80%, 109 out of 136), GP service utilisation during the last episode of illness, at 56.8% (54 out of 95), was low. The statistical analysis showed that age being younger than 35 years, lacking prior overseas experience, having an unstable immigration status, having a shorter duration of stay, and resorting to self-medication were the main barriers hindering Burmese migrants from accessing primary health care services. These findings were corroborated by the in-depth interviews.

Conclusions

Our study found that having formal access to primary health care was not sufficient to ensure GP registration and health care utilisation. Some respondents faced difficulties in registering with GP practices. Many of those who have registered prefer to forego GP services in favour of self-medication, partly due to long waiting times and language barriers. To ensure that migrants enjoy the health services they need and to which they are entitled, more proactive steps are required, including those that make health services culturally responsive.

Improvement of an ultrasensitive human immunodeficiency virus type 1 real-time reverse transcriptase-polymerase chain reaction targeting the long terminal repeat region

BACKGROUND

Human immunodeficiency virus Type 1 (HIV-1) assays applying nucleic acid testing (NAT) rely on HIV-1 sequence-specific primers and probes. Their hybridization can be limited or abolished by genetic polymorphisms occurring in the target sequence.

STUDY DESIGN AND METHODS

Blood donations are routinely tested for HIV-1/2 antibodies and for HIV-1 RNA in our blood transfusion unit. Recently, HIV-1 RNA was undetectable with an established in-house real-time long terminal repeat (LTR) reverse transcriptase-polymerase chain reaction (RT-PCR) in two cases, whereas serologic assays were positive. The reason for this discrepancy was elucidated by sequencing of the NAT target region in the respective single donations. An improved primer was designed and tested on HIV-1 reference panels and blood donations to ensure reliable detection of HIV-1 RNA.

RESULTS

Direct sequencing of the target region, isolated from samples of two unrelated HIV-positive blood donors, revealed one and four mismatches in the hybridization domain of the forward primer, respectively. Both viruses belong to HIV-1 Subtype B. LTR RT-PCR with an additional forward primer was suitable for all strains of HIV-1 tested with high sensitivity.

CONCLUSIONS

Surveillance of HIV-1 genetic diversity is essentially required to continually evaluate its impact on performance of diagnostic and patient monitoring assays.
