Henoch-Schönlein purpura nephritis with nephrotic state in children: predictors of poor outcomes.

Nephritis develops in 18-81% of Henoch-Schönlein purpura patients, and the long-term outcomes of this nephritis show great variation. A nephrotic state at disease onset has been proposed as a predictor of poor renal outcomes. We studied 42 children with Henoch-Schönlein purpura nephritis (HSPN) who presented with a nephrotic state during the early phase of the disease.

[Two cases of autosomal dominant polycystic kidney diseases who presented bilateral enlarged kidneys and severe hypertension in the neonatal period].

Autosomal dominant polycystic kidney disease(ADPKD) is rarely observed in the neonatal period. We report 2 cases of ADPKD who showed bilateral enlarged, hyperechoic kidneys and severe hypertension. It is difficult to differentiate ADPKD from autosomal recessive polycystic kidney disease (ARPKD) based on the initial clinical presentations in this period.
