Monitoring the HIV continuum of care in key populations across Europe and Central Asia.

OBJECTIVES: The aim of the study was to measure and compare national continuum of HIV care estimates in Europe and Central Asia in three key subpopulations: men who have sex with men (MSM), people who inject drugs (PWID) and migrants. METHODS: Responses to a 2016 European Centre for Disease Prevention and Control (ECDC) survey of 55 European and Central Asian countries were used to describe continuums of HIV care for the subpopulations. Data were analysed using three frameworks: Joint United Nations Programme on HIV/AIDS (UNAIDS) 90-90-90 targets; breakpoint analysis identifying reductions between adjacent continuum stages; quadrant analysis categorizing countries using 90% cut-offs for continuum stages. RESULTS: Overall, 29 of 48 countries reported national data for all HIV continuum stages (numbers living with HIV, diagnosed, receiving treatment and virally suppressed). Six countries reported all stages for MSM, seven for PWID and two for migrants. Thirty-one countries did not report data for MSM (34 for PWID and 41 for migrants). In countries that provided key-population data, overall, 63%, 40% and 41% of MSM, PWID and migrants living with HIV were virally suppressed, respectively (compared with 68%, 65% and 68% nationally, for countries reporting key-population data). Variation was observed between countries, with higher outcomes in subpopulations in Western Europe compared with Eastern Europe and Central Asia. CONCLUSIONS: Few reporting countries can produce the continuum of HIV care for the three key populations. Where data are available, differences exist in outcomes between the general and key populations. While MSM broadly mirror national outcomes (in the West), PWID and migrants experience poorer treatment and viral suppression. Countries must develop continuum measures for key populations to identify and address inequalities.

Sharp truth: health care workers remain at risk of bloodborne infection.

BACKGROUND: In 2013, new regulations for the prevention of sharps injuries were introduced in the UK. All health care employers are required to provide the safest possible working environment by preventing or controlling the risk of sharps injuries. AIMS: To analyse data on significant occupational sharps injuries among health care workers in England, Wales and Northern Ireland before the introduction of the 2013 regulations and to assess bloodborne virus seroconversions among health care workers sustaining a blood or body fluid exposure. METHODS: Analysis of 10 years of information on percutaneous and mucocutaneous exposures to blood or other body fluids from source patients infected with a bloodborne virus, collected in England, Wales and Northern Ireland through routine surveillance of health care workers reported for the period 2002-11. RESULTS: A total of 2947 sharps injuries involving a source patient infected with a bloodborne virus were reported by health care workers. Significant sharps injuries were 67% higher in 2011 compared with 2002. Sharps injuries involving an HIV-, hepatitis B virus- or hepatitis C virus (HCV)-infected source patient increased by 107, 69 and 60%, respectively, between 2002 and 2011. During the study period, 14 health care workers acquired HCV following a sharps injury. CONCLUSIONS: Our data show that during a 10-year period prior to the introduction of new regulations in 2013, health care workers were at risk of occupationally acquired bloodborne virus infection. To prevent sharps injuries, health care service employers should adopt safety-engineered devices, institute safe systems of work and promote adherence to standard infection control procedures.

Universal treatment success among healthcare workers diagnosed with occupationally acquired acute hepatitis C.

Healthcare workers (HCWs) are at risk of occupationally acquired hepatitis C. In the UK, 17 HCWs were diagnosed with occupationally acquired acute hepatitis C between 2002 and 2011. All 17 cases involved percutaneous injuries from hollowbore needles, 16 known to be contaminated with blood. Of these 17 HCWs, 15 received antiviral therapy and 14 are known to have achieved viral clearance. Treatment success was irrespective of genotype. The successful treatment of HCWs emphasizes the need for UK guidelines on the management of occupationally acquired acute hepatitis C.

Ten-year mortality trends among persons diagnosed with HIV infection in England and Wales in the era of antiretroviral therapy: AIDS remains a silent killer.

OBJECTIVES: We present national trends in death rates and the proportion of deaths attributable to AIDS in the era of effective antiretroviral therapy (ART), and examine risk factors associated with an AIDS-related death. METHODS: Analyses of the national HIV-infected cohort for England and Wales linked to death records from the Office of National Statistics were performed. Annual all-cause mortality rates were calculated by age group and sex for the years 1999-2008 and rates for 2008 were compared with death rates in the general population. Risk factors associated with an AIDS-related death were investigated using a case-control study design. RESULTS: The all-cause mortality rate among persons diagnosed with HIV infection aged 15-59 years fell over the decade: from 217 per 10 000 in 1999 to 82 per 10 000 in 2008, with declines in all age groups and exposure categories except women aged 50-59 years and persons who inject drugs (rate fluctuations in both of these groups were probably a result of small numbers). Compared with the general population (15 per 10 000 in 2008), death rates among persons diagnosed with HIV infection remained high, especially in younger persons (aged 15-29 years) and persons who inject drugs (13 and 20 times higher, respectively). AIDS-related deaths accounted for 43% of all deaths over the decade (24% in 2008). Late diagnosis (CD4 count < 350 cells/µL) was the most important predictor of dying of AIDS [odds ratio (OR) 10.55; 95% confidence interval (CI) 8.22-13.54]. Sixty per cent of all-cause mortality and 81% of all AIDS-related deaths were attributable to late diagnosis. CONCLUSIONS: Despite substantial declines, death rates among persons diagnosed with HIV infection continue to exceed those of the general population in the ART era. Earlier diagnosis could have prevented 1600 AIDS-related deaths over the decade. These findings highlight the need to intensify efforts to offer and recommend an HIV test in a wider range of clinical and community settings.

Travel for HIV care in England: a choice or a necessity?

OBJECTIVES: The aims of the study were (1) to measure the distance required to travel, and the distance actually travelled, to HIV services by HIV-infected adults, and (2) to calculate the proportion of patients who travelled beyond local services and identify socio-demographic and clinical predictors of use of non-local services. METHODS: The straight-line distance between a patient's residence and HIV services was determined for HIV-infected patients in England in 2007. 'Local services' were defined as the closest HIV service to a patient's residence and other services within an additional 5 km radius. Multivariable logistic regression was used to identify socio-demographic and clinical predictors of accessing non-local services. RESULTS: In 2007, nearly 57 000 adults with diagnosed HIV infection accessed HIV services in England; 42% lived in the most deprived areas. Overall, 81% of patients lived within 5 km of a service, and 8.7% used their closest HIV service. The median distance to the closest HIV service was 2.5 km [interquartile range (IQR) 1.5-4.2 km] and the median actual distance travelled was 4.8 km (IQR 2.5-9.7 km). A quarter of patients used a 'non-local' service. Patients living in the least deprived areas were twice as likely to use non-local services as those living in the most deprived areas [adjusted odds ratio (AOR) 2.16; 95% confidence interval (CI) 1.98-2.37]. Other predictors for accessing non-local services included living in an urban area (AOR 0.77; 95% CI 0.69-0.85) and being diagnosed more than 12 months (AOR 1.48; 95% CI 1.38-1.59). CONCLUSION: In England, 81% of HIV-infected patients live within 5 km of HIV services and a quarter of HIV-infected adults travel to non-local HIV services. Those living in deprived areas are less likely to travel to non-local services.

The impact in the UK of the Central and Eastern European HIV epidemics.

Despite increasing migration, the impact of HIV epidemics from Central and Eastern Europe (C&EE) on the UK HIV epidemic remains small. C&EE-born adults comprised 1.2% of adults newly diagnosed with HIV in the UK between 2000 and 2007. Most C&EE-born women probably acquired their infection heterosexually in C&EE. In contrast, 59% of C&EE-born men reported sex with men, half of whom probably acquired their infection in the UK. Previously undiagnosed HIV prevalence in C&EE-born sexual-health-clinic attendees was low (2007, 0.5%) as was overall HIV prevalence in C&EE-born women giving birth in England (2007, <0.1%). The high proportion of men who have sex with men (MSM) suggests under-reporting of this group in C&EE HIV statistics and/or migration of MSM to the UK. In addition to reducing HIV transmission in injecting drug users, preventative efforts aimed at C&EE-born MSM both within their country of origin and the UK are required.

Could male circumcision reduce HIV incidence in the UK?

We consider the public health relevance of three recent African clinical trials showing male circumcision (MC) to reduce female-to-male transmission of HIV for the UK. Although heterosexually acquired HIV infections now account for the majority of new diagnoses in the UK each year, it is important to note that when considering the public health relevance of MC for the UK a large majority of these infections are acquired abroad. Men who have sex with men (MSM) remain those most at risk of acquiring their HIV infection in the UK. The efficacy and effectiveness of MC among MSM and in particular its protective role in unprotected anal intercourse between men remains unknown. Any future consideration of the role of MC in reducing HIV incidence in the UK should not be at the expense of weakening existing effective interventions.

The changing epidemiology of diagnosed prevalent HIV infections in England: greatest impact on the London environs.

Data from the 1997-2004 Surveys of Prevalent HIV Infections Diagnosed were analysed by three geographical areas of residence and treatment to describe the heterogeneous growth of the HIV epidemic in England and provide projections to 2007. Between 1997 and 2004, the number of diagnosed HIV-infected adults resident in England increased by 163% (14,223 to 37,459). Within the 'London environs' the increase was 360% (742 to 3411), within the rest of England 219% (4417 to 14,088) and within London 120% (9064 to 19,960). By 2004, the London environs had the largest proportion of infections acquired through heterosexual sex (and in particular women) and the most recently diagnosed population. Projections indicate over half of diagnosed HIV-infected adults will live outside London by 2007. The epidemiology of diagnosed HIV infection within the London environs is likely to be a predictor of future trends in England overall.

Monitoring the effectiveness of HIV and STI prevention initiatives in England, Wales, and Northern Ireland: where are we now?

Primary and secondary prevention are essential components of the response to HIV and sexually transmitted infections (STIs). We present findings from nationally implemented HIV/STI prevention interventions. In 2003, of those attending STI clinics at least 64% of men who have sex with men (MSM) and 55% of heterosexuals accepted a confidential HIV test; 88% of all HIV infections in women giving birth in England were diagnosed before delivery; 85% of MSM eligible for hepatitis B vaccination received a first dose of vaccine at their first STI clinic attendance; 74% of STI clinic attendees for emergency appointments, and 20% of those for routine appointments were seen within 48 hours of initiating an appointment; the National Chlamydia Screening Programme in England found a positivity of 10% and 13% among young asymptomatic women and men, respectively. Prevention initiatives have seen recent successes in limiting further HIV/STI transmission. However, more work is required if current levels of transmission are to be reduced.

The changing epidemiology of prevalent diagnosed HIV infections in England, Wales, and Northern Ireland, 1997 to 2003.

OBJECTIVES: To present the current epidemiology of prevalent diagnosed HIV infections in England, Wales, and Northern Ireland (E, W, & NI) and describe trends over time. METHODS: Descriptive analyses of the annual national Survey of Prevalent HIV Infections Diagnosed (SOPHID) for the period 1997 to 2003. RESULTS: In 2003, 34 251 adults (15 years of age or over) were seen for HIV related care in E, W, & NI, representing a 17% increase in the prevalence of diagnosed HIV infections compared with 2002 and a 132% increase compared with 1997. Between 1997 and 2003, as a proportion of total prevalent cases, adults who acquired their infection through heterosexual sex increased from 26% to 49%; black African adults increased from 15% to 35% and diagnosed adults resident in London fell from 62% to 55% of the total. The male to female ratio declined from 5:1 to 2:1. The proportion of adults receiving combination antiretroviral therapy increased from 53% in 1998 to 64% in 2003. CONCLUSION: There has been a large increase in the number of adults with diagnosed HIV infection seen for care in E, W, & NI since 1997. Changes in the epidemiology of prevalent diagnosed HIV were seen by sex, route of infection, ethnicity, level of antiretroviral therapy, and areas of residence and treatment. In 2003, for the first time, prevalent diagnosed infections acquired through heterosexual sex over-took those acquired through sex between men. These increases have serious implications for the planning and financing of HIV services in the United Kingdom.

Recent trends in diagnoses of HIV and other sexually transmitted infections in England and Wales among men who have sex with men.

OBJECTIVES: To examine trends in rates of diagnoses of HIV and other sexually transmitted infections (STIs) in men who have sex with men (MSM) in England and Wales between 1997 and 2002. METHODS: Estimates of the MSM population living in England and Wales, London and the rest of England and Wales were applied to surveillance data, providing rates of diagnoses of HIV and STIs and age group specific rates for HIV and uncomplicated gonorrhoea. RESULTS: Between 1997 and 2002, rates of diagnoses of HIV and acute STIs in MSM increased substantially. Rates in London were higher than elsewhere. Rises in acute STIs were similar throughout England and Wales, except for uncomplicated gonorrhoea and infectious syphilis, with greater increases outside London. Rates of gonorrhoea diagnoses doubled between 1999 and 2001 (661/100,000, 1271/100,000, p<0.001) in England and Wales followed by a slight decline to 1210/100,000 (p=0.03) in 2002-primarily the result of a decline in diagnoses among men aged 25-34 (1340/100,000, 1128/100,000, p<0.001) and 35-44 (924/100,000, 863/100,000, p=0.03) in London. HIV was the third most common STI diagnosed in MSM in England and Wales and the second in London, with the highest rate (1286/100,000) found among men aged 35-44 in London in 2002. CONCLUSIONS: Rates of diagnosis of HIV and other STIs have increased substantially among MSM in England and Wales. Increases show heterogeneity by infection, geography, and age over time. Rates in London were twice those seen elsewhere, with greatest changes over time. The observed changes reflect concomitant increases in high risk behaviour documented in behavioural surveillance survey programmes.
