Resumen

Despite Southern Spain has similar HIV incidences than Eastern Europe, PrEP use is unavailable. Between January- December 2018, a sample of 167 MSM with high risk practices has been included in a cohort of informal PrEP users in Seville, the PrevenPrEP program offers counselling, follow ups and regular checkouts for HIV and other STIs.to make safer the use of on line PrEP. The educators first evaluate the real risk of the different potential prevenPrEP users. Those selected, were tested for HIV/STIs using PCR technology and they were required a general blood analytic from their GPs to evaluate the kidney and liver function. A total of 167 MSM were included in the program. All of them showed a normal biochemistry parameters and no initial HIV/STIs infections. The general characteristics of our PrevenPrEP users was similar to those shown by previous studies; an MSM of 34 years, 58% with a university degree. 85% of users showed previous HIV tests, with an average of 9 times per user. Regarding anal sex, 78,4% never used condoms during sexual intercourse with an average of 32 different sexual partners in the last 6 months, 15,6% of them were chemsex users. Finally, regarding HIV, no infection was detected in this cohort and 6,6% of them were reactive for Chlamydia, 5,4% Gonorrhoea, and 1,2% Syphilis. There has not been HIV seroconversions in this cohort during follow up. The percentage of STIs diagnosed was approximately 50% lower than those people tested in our community center who are not using PrEP, showing the importance of STIs monitorization and counselling to prevent new infections. Community centers as SevillaCheckpoint have the capacity to offer proffessional advise and monitoring services to informal PrEP users and prove to be strong candidates to offer these services when PrEP will be implemented by the Spanish Government.
