The purpose of this study was to identify hypertension in children and adolescents in an early stage of autosomal dominant polycystic kidney disease (ADPKD) by the application of ambulatory blood pressure monitoring (ABPM) over 24 h; 32 children and adolescents (mean age 12.3 +/- 4.7 years) were examined. The diagnosis was based on family history and ultrasound examination. In 21 children ADPKD was confirmed by molecular genetic analysis. ⋯ The nocturnal dip in blood pressure was reduced in 2 patients. Blood pressure correlated with renal size, but not with GFR, concentrating capacity, proteinuria, and plasma renin activity. The study reveals an early trend for increased blood pressure in children with ADPKD, requiring close supervision.

This report describes a neonate with acute renal failure associated with extensive aortic and bilateral renal artery thrombosis attributed to inadequate breastfeeding and severe dehydration. Dialytic and general supportive care, together with concurrent anticoagulation, and continuous aggressive intrathrombic instillation of urokinase for 5 days resulted in near-complete thrombolysis. ⋯ Despite ischemic atrophy of the left kidney, renal function and blood pressure were normal on follow-up. Thus, in neonates thrombolytic therapy may positively impact survival and recovery of renal function even in the setting of prolonged ischemic renal injury.
