<jats:p>A long-term follow-up study of 26 children with anaphylactoid purpura (Schönlein-Henoch Syndrome) is presented. The average length of follow-up was 4½ years. Of these 26 children, 10 were found to have an apparent latent nephritis characterized by hematuria and cylinduria, but without marked proteinuria. Nine of the ten children were over the age of 6 years at the time of onset of purpura; 6 had proteinuria or hematuria during the acute phase of the disease. It is suggested that this renal sequela of anaphylactoid purpura may constitute one of the origins of chronic renal disease "of unknown etoiology" which occurs in adult patients.</jats:p>
