Interleukin 18 as a new inflammatory mediator in left ventricular hypertrophy in children with end-stage renal disease \

الملخص EN

Left ventricular hypertrophy (LVH) represents an important determinant of increased cardiovascular morbidity and mortality (CV) in end-stage renal disease (ESRD) patients.

The role of inflammatory markers in pathogenesis of LVH in children with ESRD is not fully described.

The aim of this study is to evaluate relation of some inflammatory markers [as hs C-reactive protein (hsCRP) and interleukin (IL) 18] with LVH in children with ESRD on regular hemodialysis (HD).

This is a cross-sectional study performed on 50 children on regular HD.

Demographic data were recorded.

Echocardiography was performed at baseline to determine those with LVH.

Biochemical parameters: hemoglobin (HB), hsCRP, IL 18, phosphorus, calcium, serum albumin, and lipid profile were evaluated and correlated with LVH.

Data were analyzed using Student's t-test, and logistic regression to determine the relationship between LVH and other variables.

LVH was present in 33 (66%) participants.

Mean left ventricular mass index was 56.88 ± 22.23 g/m.2.7 Concentric remodeling, concentric hypertrophy, and eccentric hypertrophy were present in 4%, 22%, and 44% of the participants.

In univariate analysis, children with LVH had significantly lower levels of HB and serum albumin but higher levels of hsCRP, and IL 18 compared to those without LVH.

On multivariate analysis: only hsCRP, and IL 18 were significantly associated with LVH.

This study shows that elevated hsCRP and IL-18 are independent determinants of LVH in HD children.

Understanding the role of inflammatory molecules in the pathogenesis of LVH in ESRD is important for prediction of high-risk group and implementation of targeted anti-inflammatory therapies.
