[Heterohemagglutinins in human malaria: immunopathologic implications].

The prevalence of heterohemagglutinins was investigated both in sera of Africans from a malaria endemic area of Upper Volta and in sera of individuals with acute malaria from a parisian hospital. Hemagglutinins against horse, sheep, goat, chicken, pigeon and duck red blood cells were tested. The results showing an increased frequency of high titres of these hemagglutinins are discussed in terms of the mechanisms leading to autoantibody hyperproduction in malaria.
