PS-168 Long-term Renal Complications In The Regional Cohort Of Elbw Children: Correlation Between Results Aquired At The Age Of 7 And Age Of 11 Years

Abstract

Aim Assessment of renal long-term complications in the regional cohort of ELBW children born in 2002–2003. Methods 40 children (17 born as ELBW infants and 23 full-term control children randomly selected from one GP office) were assessed at the age of 7 years and next prospectively observed up to 11 years. Serum creatinine, Cystatin C, renal ultrasound and 24-hours ambulatory blood pressure measurements (ABPM) were performed. Results Mean birthweight of the ELBW group equaled 825g, and mean gestational age equaled 26.5 weeks. Mean renal volume at the age of 7 years was: ELBW group - left kidney (LK) 37ml; right kidney (RK) 40ml, control group - LK 59ml; RK 60ml (p 2 ). The mean arterial blood pressure (ABPM) increased significantly between both time points (ELBW group: 79 vs. 83, control group: 77 vs. 81 mmHg). Conclusions The smaller renal volume observed in the assessed ELBW children at the age of 7 years persisted up to the age of 11 years, however the renal function seems to be intact.
