The presence of protein in urine is a common laboratory finding in children. Although proteinuria is usually benign, it can be a marker of a serious underlying renal disease or systemic disorder. Microalbuminuria can be one of the first subclinical manifestations of endothelial dysfunction and is associated with low grade systemic inflammation. Multiple studies from the adult population suggest that microalbuminuria above the upper quartile is linked with increased risk of coronary heart disease and death even after adjustment for the presence of diabetes mellitus, obesity and hypertension. Obstructive sleep apnea (OSA) has been recognized as an independent risk factor for cardiovascular morbidity related to sympathetic nervous system overflow, metabolic dysregulation, inflammation and endothelial dysfunction secondary to repetitive hypoxia -reoxygenation events. Therefore, there is a need for further studies to investigate the association between OSA and microalbuminuria in children. Furthermore, no studies have thus far investigated the association between other sleep disorders such as periodic limb movement (PLMD) and microalbuminuria in children. Our hypothesis is that children with sleep disorders or short sleep duration have increased risk of proteinuria/microalbuminuria and that treatment and resolution of the sleep problem will be followed by improvement in proteinuria levels.
