[Stenosing ureteritis and factor XIII deficiency in anaphylactoid purpura].

Abstract

A case report of a 6-year-old boy is presented. The patient suffered from a severe Schönlein-Henoch purpura. It was demonstrated that ureteral stenosis develops during the clinical course of this disease. This complication has to be considered in anaphylactoid purpura, since it is usually self-limiting and does not require surgical intervention. This confirms once again the necessity to look for a decrease of factor XIII activity in these patients and of the value of substituting this compound if there are severe abdominal complaints. The theoretical background of this therapeutical intervention is discussed.
