ABSTRACT
INTRODUCTION: Myocardial dysfunction is a leading cause of mortality in chronic kidney disease (CKD) children specially those on regular hemodialysis. Cardiac biomarkers play a key role for early detection of myocardial injury. We aim to clarify the prognostic role of circulating cardiac biomarkers, heart type fatty acid binding protein (H-FABP) and pregnancy associated plasma protein-A (PAPP-A) in CKD children on regular hemodialysis. MATERIAL AND METHODS: This is a prospective case control study over 2 years duration. Initial assessment included 20 CKD children on regular hemodialysis and 20 age- and sex- matched healthy children as a control group. Serum level of H-FABP and PAPP-A were measured and correlated to conventional echocardiographic findings and cardiovascular outcome in CKD children. RESULTS: 60% of CKD children developed cardiovascular comorbidities. H-FABP and PAPP-A levels were significantly elevated especially in those with worse cardiovascular outcome. H-FABP and PASP-A levels were positively correlated with LVM index. At cut off point > 17.65 pg/mL, H-FABP has 91% sensitivity and 87.5% specificity for prediction of cardiac morbidity. Elevated H-FABP (OR = 33; CI 95%: 2.455 - 443.591), LVM indexed to body surface area (OR = 21; CI 95%: 1.777 - 248.103), LVM indexed to lean body mass (OR = 15; CI 95%: 1.652 -136.172), elevated PAPP-A (OR = 9.8; CI 95%: 0.898 - 106.845) and Hypertension (OR = 8.333; CI 95%: 1.034 - 67.142) are the main risk factors for cardiac morbidities in CKD children. CONCLUSIONS: Elevated H-FABP and PAPP-A are valuable prognostic markers for cardiovascular outcome in CKD children on regular hemodialysis.

Irisin and chemerin peptides expression are triggered by hypoxia and involved in activation of inflammatory cascades in various organs including the brain; however, their role in epilepsy is not fully illustrated. This study aims to explore the predictive role of irisin and chemerin for seizure control in children with idiopathic epilepsy. This cross-sectional comparative study included 50 children with idiopathic epilepsy; 25 of them had controlled seizures over the previous 6 months and 30 age- and sex-matched healthy children as controls. Epilepsy characteristics, seizure severity Chalfont score, and response to medications were assessed in relation to serum irisin and chemerin levels. In comparison to healthy controls, serum chemerin and irisin levels were significantly higher in children with idiopathic epilepsy especially those with uncontrolled seizures. Serum chemerin and irisin levels had significant positive correlation with seizure severity Chalfont score and the duration of epilepsy. Elevated Chalfont score (OR 3.19), serum chemerin (OR 2.01), and irisin (OR 2.03) are predictors of uncontrolled seizures. Circulating chemerin and irisin have 80% and 76% sensitivity and 88% and 92% specificity at cutoff point > 191.38 ng/ml and > 151.2 ng/ml respectively for prediction of uncontrolled seizures in children with idiopathic epilepsy. Elevated circulating level of irisin and chemerin may predict poor seizure control in children with idiopathic epilepsy suggesting the role of hypoxia-triggered neuroinflammation in the pathogenesis of childhood idiopathic epilepsy.
