The HepHIV 2023 conference took place from November 13th to 15th, 2023 in Madrid, Spain. Results from three research studies were presented by COBATEST network at the conference.

Dr. Megi Gogishvili presented findings of a study on HIV positive diagnosis among migrants compared to native-born in Europe and Central Asia. 

Presentation demonstrated analysis of HIV-testing trends and prevalence of HIV positive diagnosis among migrants in Europe and Central Asia (ECA) compared with native-born individuals in 2021 and 2022. All 62 CBVCTs from COBATEST network who submitted standardized aggregated or disaggregated data in both years were included in the study. As conclusions, we found that migrants in ECA had a higher risk of HIV-positive diagnoses compared to native-born individuals in both years, with increased prevalence ratio in 2022 compared to 2021. We also identified transgender migrants, MSM migrants, and MSM native-born, at higher risk of HIV-positive diagnoses compared with non-MSM, and other sex in case of transgender migrants. Further research performing analysis by migrants’ country of origin and including data from 2023 is needed to assess whether the influx of migrants from Ukraine is straining available HIV-related resources and impacting the health of newly arrived PLHIV. This analysis is of crucial importance and is need to inform future interventions to further guarantee access to HIV care and treatment to all migrants.

Dr. Miguel Alarcón Gutiérrez presented findings of a study on Chemsex, HIV testing and associated factors in gay, bisexual and other men who have sex with men (GBMSM) and transgender individuals, among European community-based centres.

A presentation consisted of analysis of associated factors with chemsex practice among GBMSM and transgender population who attended community-based voluntary counselling and HIV/STI testing (CBVCT) centres in Europe. We included 31 COBATEST Network CBVCT centres from Belgium, Italy and Spain who submitted chemsex-related questions, between 2019 and 2022. After analysis, we concluded that chemsex is a prevalent practice among GBMSM and transgender people who attend CBVCT centres and it is significantly related to HIV positive testing. Vulnerable subpopulations and specific opportunities were identified to generate interventions oriented to the prevention of chemsex related harms in the CBVCT setting.

Dr. Laura Fernández López presented a poster with the findings of a study on the assessment of HIV self-testing and self-sampling use and intention to use among COBATEST Network members. 

The poster consisted of the analysis of the use of HIV self-testing (HST) and self-sampling (HSS) among COBATEST Network members as part of the project ‘Community Led and Based HIV Services-Key to Ending the HIV Epidemic in Europe and Central Asia “Zeroing In-Ending the HIV Epidemic”‘. An online survey was conducted among COBATEST network members from February to March 2023, covering different aspects related to the use or intention to use of HST/HSS in their services. HSS was less utilized than HST among COBATEST Network members. Legal considerations posed barriers to both methods, and primary reasons for not offering them were concerns about price, follow-up, linkage to care, and concerns about self-administration without counselling. Despite high client interest, ensuring effective follow-up of test results remained a significant challenge. Please find the full results in the poster online.

The XLI Spanish Epidemiology Society (SEE) meeting took place from September 5th to 8th, 2023 in Porto, Portugal. Two abstracts were presented by COBATEST network at the meeting.

Dr. Megi Gogishvili presented an abstract on the impact of COVID-19 on HIV-testing among community centers in Catalonia. 

Presentation consisted of time series analysis of the testing trends from 2018 to 2020. Four periods were analysed: pre-lockdown (PRE), lockdown (LD), de-escalation (DE), and new normality (NN). In total, 18,265 tests were reported. Males comprised 56.1% of testers in PRE, 71.4% in LD and 49.5% in NN, while largest proportion of females were found in DE (54.1%). During PRE 10,034 tests were performed, during LD 82 (84.4% less than expected), 211 during DE (62.5% less), and 2305 in NN, which is 12.5% less than predicted by the model according to the previous trends. Males had the highest difference in expected to observed tests (LD = 86.3%, DE = 73.9% and NN = 24.3% less than expected). Females tested 81.1% (LD) and 37.5% (DE) less than expected and 2.9% more than expected during NN. Transgenders tested 86.7% less than expected in LD, 92.9% in DE, and 25.2% in NN. Meno who have sex with men (MSM) tested 87.9% less than expected during LD, 84.8% during DE, and 34.5% during NN. Sex workers (SWs) tested 86.5%, 83.1%, and 33.8% less than expected. People who inject drugs (PWIDs) tested 62.5%, 46.2%, and 33.3% less than expected. Migrants tested 84.9%, 51.1% less than expected and 10.4% more during NN. Please find full presentation online.

Dr. Miguel Alarcón Gutiérrez presented an abstract based on analysis of quantitative data collected by COBATEST network members from 2013 to 2022 concentrating on transgender individuals and men who have sex with men (MSM).

A presentation consisted of analysis of HIV and other STI associated factors among MSM and transgender individuals in 60 European community-led testing centers from COBATEST network. Out of 81,776 testers were GBMSM and 1,603 were transgender individuals. Total reactive testing prevalence among GBMSM population was 5.89% (CI: 5.64-6.14), and 12.48% (CI: 10.90-14.19) among transgender individuals. Multivariate analysis in GBMSM showed that factors associated with reactive testing were: age (aOR=1.01; CI: 1.00-1.01), being a migrant from outside of European Union (EU) (aOR=1.77; CI: 1.56-2.00), have been previously tested for HIV (aOR=1.37; CI: 1.19-1.59), having any risk exposure as motivation for testing (aOR=1.64; CI: 1.46-1.85), condomless penetration during last sexual intercourse (aOR =1.34; CI: 1.21-1.49), previous STIs (aOR=2.04; CI: 1.78-2.33), and receiving money or drugs for sex during last 12 months (aOR=1.61; CI: 1.35-1.93). In transgender population, factors associated with reactive testing were being a migrant from outside of the EU (aOR=2.90; CI: 1.55-5.42), having any risk exposure as motivation for testing (aOR=1.95; CI: 1.39-2.74), previous STIs (aOR=1.60; CI: 1.07-2.39), and receiving money or drugs for sex during last 12 months (aOR=2.04; CI: 1.10-3.77).
