BACKGROUND: Cardiovascular disease (CVD) is the major cause of mortality in end-stage kidney disease (ESKD) patients. Aortic root dilatation (ARD) was recently recognized as a cardiovascular (CV) sequela in these patients. This study aims to evaluate the prevalence, risk factors, and progression of ARD in children with ESKD on regular hemodialysis (HD) and after kidney transplantation (KT).
METHODS: Seventy children in HD (HD group) and 80 pediatric kidney transplant recipients (KTR) (KT group) were included. The echocardiographic assessment was done twice at intervals of more than 6 months (6-14 months) except for 3 patients who died before the second assessment.
RESULTS: ARD's overall prevalence was higher in HD than in KT groups (71.4% and 40%). ARD was more prominent in patients with increased duration of ESKD, EDW, normalized IDWG%, and normalized UF vol%. In the KTR group, underweight was more prevalent among the ARD group than the non-ARD group. Patients with ARD had higher BP than patients without ARD. Most of the patients with ARD were on classic triple immunosuppressive therapy. ARD patients of both groups had lower HB, higher PLTS, Ph, Ca × Ph levels, and lower e-GFR than non-ARD patients.
CONCLUSION: ARD is prevalent among ESKD children, with furthermore prevalence in HD than in KT patients. Younger age, lower BMI Z-scores, hypertension (HTN), and increased Ca × Ph are risk factors for ARD. Aortic root measures and ARD frequency decrease on ≥ 6-month follow-up of patients.
