AB AIMS: To determine the impact of the expanded 1993 European AIDS case
definition on the distribution of adult AIDS cases in Europe. METHODS:
The 1993 European AIDS surveillance case definition, implemented in the
European region in 1993, comprises three new indicator diseases
(pulmonary tuberculosis, recurrent pneumonia and invasive cervical
cancer). Its impact on the surveillance of AIDS (defined as the total
number of adult AIDS cases fitting solely the new case definition
divided by the total number of AIDS cases diagnosed since the date of
implementation in each country) was assessed using data from the
European Non Aggregate AIDS Data Set (ENAADS) updated December 1993. The
impact was also calculated by country and transmission category.
RESULTS: A total of 471 AIDS cases fitting solely the new case
definition were reported in 1993 by 27 of the 45 countries of the WHO
European Region (impact: 471/9891 = 4.7%). Impact varied by country from
1.7% in Italy to 10.7% in Portugal and was high in some countries with
small numbers of AIDS cases. Detailed break-down of 421 cases was
available for 14 countries. In these countries 30% of the cases fitting
solely the new definition were female, 65% presented with pulmonary
tuberculosis, 28% with recurrent pneumonia and 7.4% with invasive
cervical cancer. The impact by transmission category was: 7.6% for the
heterosexual contact group, 5.7% for the injecting drug users (IDU), and
2.6% for the homo/bisexual group. CONCLUSION: At present the overall
impact of the expanded 1993 AIDS case definition on surveillance is
small (4.7%), although it remains to be assessed over a longer time
period. Nevertheless the impact is more substantial in some countries
and some transmission categories (heterosexual contact, IDU) and its
implementation has enabled to better encompass the most severe
manifestations of HIV infection.
