EuroSIDA

EuroSIDA is a prospective observational cohort study following adult persons with HIV. The study aims to follow the long-term clinical outcomes for the general population of people with HIV in Europe and to assess the impact of antiretroviral drugs (ART) on these outcomes. Initiated in 1994, EuroSIDA marked its 25th anniversary in 2019 and continues to evolve in multiple ways. As an observational cohort, the scope of data collected has expanded considerably over time, reflecting changes in the clinical care of people with HIV and the increasing life expectancy of this population.

The study includes data from 118 collaborating clinics across 39 countries, covering all European regions, as well as Israel and Argentina (see the EuroSIDA study group here). The EuroSIDA database holds data from more than 24,500 individuals contributing nearly 200,000 person-years of follow-up. In addition, the unique EuroSIDA plasma repository includes more than 200,000 stored samples. Annual data collection includes key demographic characteristics, clinical events, ART history, hepatitis C treatment and other medications, laboratory measurements and plasma samples. To date, EuroSIDA has contributed to nearly 338 peer-reviewed publications (h-index 52), addressing a broad range of scientific focus areas.

In 2017, EuroSIDA was one of the founding cohorts the International Cohort Consortium of Infectious Disease (RESPOND), a collaborative cohort consortium focused on infectious diseases. EuroSIDA has also played an important role in numerous international collaborations, including the D:A:D study, ART-CC, COHERE and many others.
