title: The complement system in hemolytic-uremic syndrome in childhood.
abstract: A dynamic estimation of the complement system was obtained by immunochemical estimation of C3, C4, C5, C1q, C3b + C3c, C3d, Ba in children with hemolytic-uremic syndrome. The presence of increased breakdown products of C3 (C3b + C3c, C3d) and of factor B (Ba) suggests an activation of the complement system possibly by the alternative pathway. No definite explanation for these complement abnormalities can be given.
