[Nephropathy in the course of Schönlein-Henoch purpura].

: The aim of the study was to assess the frequency of renal complications and also evaluation of renal efficiency with regard to sex and age in children with Schonlein-Henoch purpura. 31 children with Schonlein-Henoch disease out of 5004 hospitalised in 6 years time (1994-1999) in Mil. Medical University-Dpt of Pediatrics, underwent the examination, which is 0.62% of all patients. The group of analysed cases consisted of 19 girls (61.3%) and 12 boys (38.7%). 15 of them had changes in kidneys, which constitutes 48.4%. The average age of examined children was 9.1 years. In the most cases upper respiratory tract infections preceded symptoms of the Schonlein-Henoch purpura. The most often complications found in the course of the Schonlein-Henoch purpura were renal ones. The most numerous renal complications affected children between 7 and 9 years of age. Because of chronic and insidious course of the disease, children, after discharging from hospital should stay under specialistic medical care.
