[Papillon-Lefèvre syndrome and recurrent infections].

Seven cases of Papillon-Lefevre syndrome are described, 4 children and their mother with two other relatives on the mother's side. An immune defect was suspected because six of the seven had a history of severe pyogenic infections, but the results of the tests were not the same in the three individuals tested. In one patient no immune defect was detected but in the other two the response of lymphocytes to candida and to streptokinase and streptodornase was reduced.
