RESUMEN
BACKGROUND: Since 1996, there has been a resurgence in sexually transmitted infections (STIs) among men who have sex with men (MSM) in Western Europe. This has coincided with a significant decrease in HIV-associated mortality following the introduction of highly active antiretroviral therapies (HAART) and a corresponding increase in the number of MSM living with HIV. Levels of unprotected anal intercourse have also increased. In this article, we use STI surveillance data from a number of Western European countries to better understand the contribution of HIV-positive MSM to the recent increase in STIs. METHODS: Published literature, surveillance reports, and ad hoc publications relating to HIV prevalence trends and STIs among HIV-positive MSM in Western Europe were reviewed. RESULTS: Post-HAART, HIV prevalence among community samples of MSM ranged from 5% to 18%. HIV prevalence among MSM diagnosed with an STI was substantially higher. On average, HIV prevalence among MSM diagnosed with syphilis in 11 countries was 42% (range 14%-59%). Most HIV-positive MSM with syphilis were aware of their HIV status. In England and Wales, 32% of MSM with gonorrhea were HIV-positive in 2004. Outbreaks of lymphogranuloma venereum have been documented in 9 countries; HIV-positive MSM accounted for 75% of cases on average (range 0%-92%). Cases of sexually transmitted hepatitis C have been predominantly identified among HIV-positive MSM in Rotterdam, Paris, Amsterdam, and the United Kingdom. CONCLUSIONS: In Western Europe, STIs have been disproportionately diagnosed among HIV-positive MSM post-HAART. Improved survival coupled with serosorting among HIV-positive MSM appears to explain the high prevalence of HIV among MSM with STIs. STI transmission among HIV-positive men will have contributed substantially to increasing STI trends seen among MSM in Western Europe, since 1996. These findings highlight the need for routine STI testing among HIV-positive MSM as well as safer sex messages highlighting the implications of STI coinfection.

BACKGROUND: Recent reports suggest an increase in sexually-transmitted hepatitis C infection among HIV-infected men who have sex with men (MSM) in European cities. We investigated whether current national surveillance systems in England and Wales (E&W) are able to monitor sexual transmission of hepatitis C infection among HIV-infected MSM. METHODS: Routine laboratory reports of hepatitis C diagnoses and data from sentinel hepatitis C testing surveillance were matched to HIV diagnosis reports to determine: (i) the number of MSM diagnosed with HIV and hepatitis C (1996-2003); (ii) the number of HIV-diagnosed MSM tested for hepatitis C and found to be positive at sentinel sites (2003). RESULTS: (i) Between 1996-2003, 38,027 hepatitis C diagnoses were reported; 25,938 (68%) were eligible for matching with HIV diagnoses. Thirty-one men (four in London) had both a HIV and hepatitis C diagnosis where the only risk was sex with another man. Numbers of "co-diagnosed" MSM increased from 0 in 1996 to 14 in 2003. The majority of MSM (22/31) tested hepatitis C positive after HIV diagnosis. (ii) Of 78,058 test results from sentinel hepatitis C testing sites in 2003, 67,712 (87%) were eligible for matching with HIV diagnoses. We identified 242 HIV-diagnosed MSM who did not inject drugs who tested for hepatitis C in 2003; 11 (4.5%) tested hepatitis C positive (95% CI: 2.3%-8.0%). Applying this percentage to all MSM seen for HIV-related care in E&W in 2003, an estimated 680 MSM living with diagnosed HIV would have tested positive for sexually-transmitted hepatitis C (95% CI: 346-1208). CONCLUSION: Matching routine laboratory reports of hepatitis C diagnoses with HIV diagnoses only identified 31 HIV infected MSM with sexually-transmitted hepatitis C infection. Clinical studies suggest that this is an underestimate. On the other hand, matching sentinel surveillance reports with HIV diagnoses revealed that in E&W in 2003 nearly 5% of HIV-diagnosed MSM tested hepatitis C positive where the only risk was sex with another man. Reports of sexually-transmitted hepatitis C infection were not confined to London. Enhanced surveillance is needed to monitor sexually-transmitted hepatitis C among HIV-infected MSM in E&W.

OBJECTIVES: To describe the proportion of HIV-infected heterosexual individuals diagnosed late and estimate how much mortality could have been prevented by earlier diagnosis. DESIGN: A population-based study using surveillance reports from England and Wales. METHODS: Calculation of proportions diagnosed late (CD4 cell count < 200 cells/mul) and short-term mortality (death within a year of diagnosis). RESULTS: A total of 16 375 heterosexual individuals were diagnosed with HIV (2000-2004): 10 503 with CD4 cell counts available at that time; 42% (4425) were diagnosed late. Late diagnosis increased with age (P < 0.01). One fifth of women diagnosed antenatally were diagnosed late compared with 42% of other women and 49% of men; 70% of all heterosexuals diagnosed were black Africans, born and infected in Africa. Of those, at least 40% were recent arrivals to the UK, and twice as many were diagnosed late as black-African heterosexuals infected in the UK. Short-term mortality was 3.2% (491/15 523); 6.1% among those diagnosed late and 0.7% among others (P < 0.01). Short-term mortality was lower among black-African compared with white heterosexuals (3.1 versus 4.5%; P < 0.01) because of diagnosis at a younger age. Earlier diagnosis would have reduced short-term mortality by 56% (249 fewer deaths) and all mortality by 32% between 2000 and 2004. CONCLUSION: Groups at high risk of late diagnosis should be targeted for health promotion activities, opportunistic screening, and removal of any barriers to testing. HIV testing in a variety of settings would reduce missed diagnoses and costs. New patient checks in primary care may provide the earliest opportunity to diagnose HIV infection among recent arrivals to the UK.

OBJECTIVES: To present national trends of the estimated number and proportion of late HIV diagnoses and short-term mortality following diagnosis among men who have had sex with men (MSM). To determine separately risk factors for late diagnosis and short-term mortality. METHODS: Analysis of national HIV/AIDS case reports of new diagnoses linked to CD4 cell counts from the CD4 Surveillance Scheme. Inverse probability weighting adjusted for individuals with no CD4 cell count at diagnosis. Outcomes were late diagnosis (CD4 cell count <200 x 10(6) cells/l at diagnosis) and short-term mortality (death within 1 year of diagnosis). RESULTS: Of 14,158 new diagnoses, 31% were estimated as late diagnoses. Despite a decreasing trend (P trend <0.01) an estimated 430 (25%) MSM were still diagnosed late in 2001. Late diagnosis disproportionately affected individuals diagnosed outside London, of non-white ethnicity, and of older age. There were 710 (5.0% of 14 158) deaths within a year of HIV diagnosis. Estimated short-term mortality was 14% for MSM diagnosed late and 1% for other MSM (adjusted odds ratio, 10.8; 95% confidence interval, 7.7-15.9). Short-term mortality declined concurrently with availability of highly active antiretroviral therapy and was independently associated with age and diagnosis outside London but not ethnicity. CONCLUSIONS: The continued late diagnosis of one in four MSM means these individuals lose the option to start therapy early, miss opportunities to prevent further transmission and are approximately 10 times more likely to die within a year of diagnosis. Early diagnosis of all MSM in 2001 could have reduced short-term mortality by 84% and all mortality in that year by 22%.

OBJECTIVE: To predict trends in diagnosed HIV prevalence by extrapolation to 2004 using data from the annual surveys of individuals receiving HIV-related care in England, Wales and Northern Ireland from 1996 to 2001. METHODS: Data from the annual surveys of prevalent HIV infections diagnosed (SOPHID) were adjusted for under-reporting and non-attendance and separately extrapolated for infections acquired homosexually, heterosexually and by other routes. The data were extrapolated using negative binomial and linear regression models based on the 1996 to 2001 annual surveys. RESULTS: The negative binomial model predicted an increase of 56% in diagnosed HIV prevalence in England, Wales and Northern Ireland between 2001 and 2004. The linear model predicted an increase of 25% for the same time period. The predicted increases are mostly driven by the large rise in the number of new diagnoses, in particular in individuals infected heterosexually. CONCLUSION: Increases in HIV prevalence in England, Wales and Northern Ireland have diverged from a linear trend. Negative binomial modelling of the data predicts that large rises in prevalence will continue during the early 2000s.

The majority of those infected and affected by HIV are younger adults. The ability of highly active antiretroviral therapies (HAART) to extend survival means that those infected when younger may reach older age, and future increases in numbers of older individuals living with HIV in England, Wales and Northern Ireland (E,W&NI) are expected. Evidence that older individuals engage in risky sexual behaviours suggests potential for HIV transmission. Data from national HIV/AIDS surveillance systems were reviewed (1997-2001). An older individual is defined as aged 45 years or over. Between 1997 and 2001, 2290 older individuals were diagnosed with HIV; 361 in 1997, rising to 648 in 2001. Heterosexual acquisition accounted for 1073 (47%) infections; 662 were male. Where reported, 666 (65%) older heterosexuals were probably infected in Africa, 144 (14%) in the United Kingdom and 113 (11%) in Asia. There were 1020 (45%) new diagnoses acquired homosexually; white (92%), infected in the United Kingdom (78%). Numbers of older individuals accessing HIV-related services more than doubled between 1997 (2488) and 2001 (5175). In 2001, 2270 (53%) were London residents. Between 1997 and 2001, among HIV-infected older individuals attending genitourinary medicine (GUM) clinics, the proportions previously undiagnosed were 60% and 82% in heterosexual males and females respectively, and for men who have sex with men (MSM), 42%. Numbers of older individuals newly diagnosed with HIV have increased in recent years. The increase in numbers of older individuals accessing HIV-related services were in excess of younger adults. A significant proportion of older HIV-infected female heterosexuals and MSM were undiagnosed. Awareness must be raised among clinicians, and an 'aged response' to HIV is required.

Developments over the last decade in legislation and professional guidance on confidentiality and medical research in the UK are reviewed. Despite the General Medical Council's guidance, and recent changes to the common law on confidentiality in England and Wales, confusion remains about what is lawful and professionally acceptable in the handling of identifiable data. The GMC has contributed to this confusion. Professional bodies should jointly produce new guidance. The Health and Social Care Act 2001 is a temporary legislative solution. Public consensus is required on an acceptable balance between the citizen's right to privacy and the responsibility of society--to which all citizens belong--to protect the public health. The Government should survey public opinion, inform NHS patients better, initiate wide public debate, and legislate to protect both citizens' rights and medical research that is demonstrably in the public interest. Registration of cancer and communicable diseases should become statutory.
