[Comparison of hospital prevalence of rheumatic heart diseases and acute rheumatic arthritis in France and Africa].
This study reports the results of a multicentre enquiry performed in France in 1990 which included 41,242 adults hospitalised in Cardiology Units, 33,907 children hospitalised in Pediatric departments and 8,868 soldiers. A comparative enquiry was also carried out in North Africa (Tunis) and West Africa (Abidjan, Ouagadougou). The results of the French arm of the enquiry showed that rheumatic heart disease (RHD) has become very rare in adults (3.1% of all cardiac disease) and that it tends to occur in older subjects (average 54.4 years of age). There is practically no RHD in young adults. This decreased prevalence of RHD is confirmed in children in whom this diagnosis represents only 0.04% of cases of all cardiac disease--of which 87.5% are of extra-European origin. In contrast, there is a high frequency of RHD in Tunisia (29.3%) and West Africa (13.2% in Abidjan and 13% in Ouagadougou). The disease remains active as is shown by the age of affected adults in Africa (average 21 and 27 years of age). The results also show a reduction to a very low prevalence of acute rheumatic fever in French pediatric departments (0.005%). The authors discuss the reasons for the persistence of endemic infection in Africa: virulence of the streptococcus, predisposing factors (HLA group?), geographic factors and, above all, socioeconomic factors and difficulties in obtaining treatment and prophylaxis. A movement of international cooperation is suggested in order to combat RHD in Africa, especially with regards to its prevention in childhood.(ABSTRACT TRUNCATED AT 250 WORDS)
