An update on the performance of STI services for gay and bisexual men across European cities: results from the 2017 European MSM Internet Survey. Sex Transm Infect 2020; 97:201-208. [PMID: 33144345 DOI: 10.1136/sextrans-2020-054681] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2020] [Revised: 09/15/2020] [Accepted: 09/17/2020] [Indexed: 11/03/2022] Open
Abstract
OBJECTIVES Rectal STIs compromise health and are common in men who have sex with men (MSM). However, the European-MSM-Internet-Survey (EMIS-2010) showed that in 2010, the prevalence of anal swabbing during STI screening by MSM varied widely across 40 European cities. In this paper, we replicate a variety of measures of STI testing performance using 2017-18 data and extending the geographic spread of the analysis. METHODS Data were analysed from the EMIS-2017, a 33-language online sexual health survey accessible from 18 October 2017 to 31 January 2018. We focus on a subsample of 38 439 respondents living in the same 40 European cities we reported on in 2010. For a broader perspective, we also included an additional 65 cities in the analysis (combined n=56 661). We compared the prevalence of STI screening in MSM and disclosure of same-sex sexual contacts to the healthcare provider. We applied multivariable logistic regression models to compare the odds of MSM receiving each of four diagnostic procedures, including anal swabbing in the previous 12 months, controlling for age, HIV diagnosis, pre-exposure prophylaxis use and number of sexual partners. RESULTS In 2017, across 40 European cities, the proportion of respondents screened for STIs ranged from under 19% in Belgrade to over 59% in London. At an individual level, in comparison to London, the adjusted OR (AOR) of having received anal swabbing ranged from 0.03 in Belgrade, Bucharest and Istanbul to 0.80 in Oslo, with little evidence for a difference in Amsterdam and Dublin. Since 2010, most cities in West and South-west Europe have substantially narrowed their performance gap with London, but some in East and South-east Europe have seen the gap increase. CONCLUSIONS Although comprehensive STI screening in MSM has expanded across many European cities, the low prevalence of anal swabbing indicates that rectal STIs continue to be underdiagnosed, particularly in East/South-east Europe.

Estimating the burden of HIV late presentation and its attributable morbidity and mortality across Europe 2010-2016. BMC Infect Dis 2020; 20:728. [PMID: 33028235 PMCID: PMC7541282 DOI: 10.1186/s12879-020-05261-7] [Citation(s) in RCA: 34] [Impact Index Per Article: 8.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2020] [Accepted: 07/16/2020] [Indexed: 01/12/2023] Open
Abstract
BACKGROUND Late presentation (LP), defined as a CD4 count < 350/mm3 or an AIDS-event at HIV-diagnosis, remains a significant problem across Europe. Linking cohort and surveillance data, we assessed the country-specific burden of LP during 2010-2016 and the occurrence of new AIDS events or deaths within 12 months of HIV-diagnosis believed to be attributable to LP. METHODS Country-specific percentages of LP and AIDS-events/death rates (assessed with Poisson regression) observed in The Collaboration of Observational HIV Epidemiological Research Europe (COHERE) and EuroSIDA cohorts, were applied to new HIV-diagnoses reported to the European Centre for Disease Prevention and Control. The estimated number of LP in the whole population was then calculated, as was the number of excess AIDS-events/deaths in the first 12 months following HIV-diagnosis assumed to be attributable to LP (difference in estimated events between LP and non-LP). RESULTS Thirty-nine thousand two hundred four persons were included from the COHERE and EuroSIDA cohorts, of whom 18,967 (48.4%; 95% Confidence Interval [CI] 47.9-48.9) were classified as LP, ranging from 36.9% in Estonia (95%CI 25.2-48.7) and Ukraine (95%CI 30.0-43.8) to 64.2% in Poland (95%CI 57.2-71.3). We estimated a total of > 320,000 LP and 12,050 new AIDS-events/deaths attributable to LP during 2010-2016, with the highest estimated numbers of LP and excess AIDS-events/deaths in Eastern Europe. Country-level estimates of excess events ranged from 17 AIDS-events/deaths (95%CI 0-533) in Denmark to 10,357 (95%CI 7768-147,448) in Russia. CONCLUSIONS Across countries in Europe, the burden of LP was high, with the highest estimated number of LP and excess AIDS-events/deaths being in Eastern Europe. Effective strategies are needed to reduce LP and the attributable morbidity and mortality that could be potentially avoided.

[PMID: 32190387 PMCID: PMC7068150 DOI: 10.1155/2020/1379676] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2018] [Accepted: 01/21/2020] [Indexed: 11/23/2022] Open
Abstract
In response to invasion by the human immunodeficiency virus (HIV), the self-regulatory immune system attempts to restore the CD4+ count fluctuations. Consequently, many clinical covariates are bound to adapt too, but little is known about their corresponding new optimal set points. It has been reported that there exist few strongest clinical covariates of the CD4+ count. The objective of this study is to harness them for a streamlined application of multidimensional viewing lens (statistical models) to zoom into the behavioural patterns of the adaptive optimal set points. We further postulated that the optimal set points of some of the strongest covariates are possibly controlled by dietary conditions or otherwise to enhance the CD4+ count. This study investigated post-HIV infection (acute to therapy phases) records of 237 patients involving repeated measurements of 17 CD4+ count clinical covariates that were found to be the strongest. The overall trends showed either downwards, upwards, or irregular behaviour. Phase-specific trends were mostly different and unimaginable, with LDH and red blood cells producing the most complex CD4+ count behaviour. The approximate optimal set points for dietary-related covariates were total protein 60-100 g/L (acute phase), <85 g/L (early phase), <75 g/L (established phase), and >85 g/L (ART phase), whilst albumin approx. 30-50 g/L (acute), >45 g/L (early and established), and <37 g/L (ART). Sodium was desirable at approx. <45 mEq/L (acute and early), <132 mEq/L (established), and >134 mEq/L (ART). Overall, desirable approximates were albumin >42 g/L, total protein <75 g/L, and sodium <137 mEq/L. We conclude that the optimal set points of the strongest CD4+ count clinical covariates tended to drift and adapt to either new ranges or overlapped with the known reference ranges to positively influence the CD4+ cell counts. Recommendation for phase-specific CD4+ cell count influence in adaptation to HIV invasion includes monitoring of the strongest covariates related to dietary conditions (sodium, albumin, and total protein), tissue oxygenation (red blood cells and its haematocrit), and hormonal control (LDH and ALP).

Abstract
OBJECTIVE To describe a Norwegian low-threshold HIV testing service targeting men who have sex with men (MSM). DESIGN AND SETTING After the HIV testing consultation, all users of the HIV testing service were invited to answer the study questionnaire. The study setting included the sites where testing was performed, that is, the testing service's office in Oslo, cruising areas, bars/clubs and in hotels in other Norwegian cities. PARTICIPANTS MSM users of the testing service. PRIMARY AND SECONDARY OUTCOME MEASURES Data were collected on demographics, HIV testing and sexual behaviour as well as the participant's motivations for choosing to take an HIV test at this low-threshold HIV testing service. The data are stratified by testing site. RESULTS 1577 HIV testing consultations were performed, the study sample consisted of 732 MSM users. 11 tested positive for HIV. 21.7% had a non-western background, 27.1% reported having a non-gay sexual orientation. 21.9% had 10 or more male sexual partners during the last year, 27.9% reported also having had a female sexual partner. 56.4% reported having practised unprotected anal intercourse during the last 6 months. 20.1% had never tested for HIV before. Most of these user characteristics varied by testing sites. CONCLUSIONS The Norwegian low-threshold testing service recruits target groups that are otherwise hard to reach with HIV testing. This may indicate that the testing service contributes to increase HIV testing rates among MSM in Norway.

Abstract
The non-decreasing incidence of HIV among men who have sex with men (MSM) has motivated the emergence of Community Based Voluntary Counselling and Testing (CBVCT) services specifically addressed to MSM. The CBVCT services are characterized by facilitated access and linkage to care, a staff largely constituted by voluntary peers, and private not-for-profit structures outside the formal health system institutions. Encouraging results have been measured about their effectiveness, but these favourable results may have been obtained at high costs, questioning the opportunity to expand the experience. We performed an economic evaluation of HIV testing for MSM at CBVCT services, and compared them across six European cities. We collected retrospective data for six CBVCT services from six cities (Copenhagen, Paris, Lyon, Athens, Lisbon, and Ljubljana), for the year 2014, on the number of HIV tests and HIV reactive tests, and on all expenditures to perform the testing activities. The total costs of CBVCTs varied from 54,390€ per year (Ljubljana) to 245,803€ per year (Athens). The cost per HIV test varied from to 41€ (Athens) to 113€ (Ljubljana). The cost per HIV reactive test varied from 1966€ (Athens) to 9065€ (Ljubljana). Our results show that the benefits of CBVCT services are obtained at an acceptable cost, in comparison with the literature (values, mostly from the USA, range from 1600$ to 16,985$ per HIV reactive test in clinical and non-clinical settings). This result was transversal to several European cities, highlighting that there is a common CBVCT model, the cost of which is comparable regardless of the epidemiological context and prices. The CBVCT services represent an effective and "worth it" experience, to be continued and expanded in future public health strategies towards HIV.
