Framework programme:

EC contribution:

48 months
Starting date:

The primary objective of EuroSIDA is to study demographic, clinical, therapeutic, virological and laboratory data from persons infected with HIV across Europe in order to determine the long-term virological, immunological and clinical outcome.

A total of 16,100 consecutive patients from 90 clinical centres in 33 European countries and Argentina – one quarter from Eastern Europe – will be followed-up on a long-term basis. New patients will be recruited periodically in 2005 and 2007, to ensure all the regions of Europe where the epidemic is prevalent are represented. This will allow the study to give timely information on the clinical presentation and outcome of European patients infected with HIV, as well as long-term follow-up. By November 2009, it is projected that a total of 83,000 prospective person-years of follow-up will have been collected within EuroSIDA (with a prospective follow-up of up to 15 years).

Most of the data collected from the clinics are derived from assessments done as part of routine care. Intense control programmes are implemented to ensure optimal quality of all aspects of the conduct of the study.

Over the years, EuroSIDA has led and/or contributed to a series of collaborations with other studies on clinical questions that the study was not sufficiently well powered to address by itself. Related to this, a series of activities within EuroSIDA has focused on standardising the methods used in observational studies and controlled clinical trials.
