Abstract
chronic kidney diseases can be defined as either renal injury (proteinuria) and or glomerular filtration rate <60 ML/min/1.73 M2 for more than 3months (KDOQI,2008). Adequate nutrition is a concern for all children with chronic kidney disease (CKD) because of the impact of nutritional intake on growth and neurodevelopment, and the associations between nutritional status and mortality(Wong et al., 2000). Children with chronic kidney diseases frequently have suboptimal nutritional intake compared to healthy children due to many factors mainly anorexia which is caused by many factors including altered taste, elevated level of many cytokines includingIL1,IL6,TNF(Cheung et al., 2010) also changes in appetite regulating hormones(Mak et al ., 2010). Adequate nutritional status can be defined as maintenance of a normal pattern of growth and a normal body composition by consumption of appropriate amounts and types of food(Foster., et al, 2004),so optimum nutrition is needed to avoid effect of malnutrion on patient with chronic kidney diseases which mainly affect linear growth(KDOQI., 2009). Nutritional assessment of children with chronic kidney diseases depends mainly on anthropometric measures plotting these measures against most recent WHO growth charts (WHO Multicentre Growth Reference Study,2006) , and on many laboratory investigations . Good nutritional management of children with chronic kidney disease (including adequate supply of energy, macro and micro nutrients ,fluids, minerals) and treatment of associated morbidities with chronic kidney diseases e.g. GERD and gastric dysmotility which is common (De and Taylor, 2007) and enhanced dialytic clearance can promote better growth patterns(Fischbach et al.,2006).
