“…Autopsy was performed in 8 patients who died and histological examination of heart and vessels was performed (patients 2,4,8,9,11,12,13,15). In all but 1 patient (patient 15), left ventricular hypertrophy was found.…”
Survival and causes of death in children dialyzed in a single center were analyzed. During the last 12 years a chronic dialysis program was introduced in 146 children in our center and 125 of them, eligible for observation, were included in this analysis; 58 patients were on hemodialysis (HD) and 67 on peritoneal dialysis [continuous ambulatory peritoneal dialysis/automated peritoneal dialysis (CAPD/APD)]. Mean age at the start of dialysis was 13.1 years in HD and 9.8 years in CAPD/APD patients. Overall, 16 patients died (12.5%); 6 (10.3%) on HD and 10 (14.9%) on CAPD/APD; 4 HD patients died of hemorrhagic stroke and 2 were killed in road traffic accidents. Of 10 CAPD/APD patients, 7 died of heart failure, ischemic stroke, and/or disseminated thromboembolic disease. Another was killed in a road traffic accident and 2 died during the course of severe infections. The 1-year patient survival rate was 96.6% in HD patients and 95% in CAPD/APD patients, 2-year survival 94% and 93% and 5-year survival 91% and 78%, respectively (P=0.2, NS). In conclusion, the survival rate for HD and CAPD patients is similar, although after 2 years of therapy, it is lower in CAPD patients. The main causes of death are cardiovascular. However, in CAPD/APD patients, heart failure with low cardiac output and thromboembolic complications are major causes of death, and in HD patients the main cause is hemorrhagic stroke.

“…2). The main risk factors for uremic cardiomyopathy are the same as for uremic arteriopathy, and both uremic arteriopathy and cardiomyopathy are exaggerated by traditional CV risk factors and accelerate in CKD stage 5 [43]. Fig.…”
Section: The Pathological Basis Of Cardiovascular Complications In Chmentioning
Visceral obesity and metabolic abnormalities typical for metabolic syndrome (MS) are the new epidemic in adolescence. MS is not only the risk factor for cardiovascular disease but also for chronic kidney disease (CKD). Thus, there are some reasons to recognize MS as a new challenge for pediatric nephrologists. First, hypertensive and diabetic nephropathy, the main causes of CKD in adults, both share the same pathophysiological abnormalities associated with visceral obesity and insulin resistance and have their origins in childhood. Secondly, as the obesity epidemic also affects children with CKD, MS emerges as the risk factor for progression of CKD. Thirdly, metabolic abnormalities typical for MS may pose additional risk for cardiovascular morbidity and mortality in children with CKD. Finally, although the renal transplantation reverses uremic abnormalities it is associated with an exposure to new metabolic risk factors typical for MS and MS has been found to be the risk factor for graft loss and cardiovascular morbidity after renal transplantation. MS is the result of imbalance between dietary energy intake and expenditure inducing disproportionate fat accumulation. Thus, the best prevention and treatment of MS is physical activity and maintenance of proper relationship between lean and fat mass.
“…LV hypertrophy occurs in 40%-75% of the pediatric ESRD population depending on the classification of LV hypertrophy [24,25,26,27,28]. At initiation of dialysis, 69% of subjects aged 4-18 years had evidence of LV hypertrophy [24].…”

“…The LV mass index in the dialysis population is almost twice that of the healthy controls [23]. Frequent monitoring of the pediatric dialysis population is warranted, with a 40%-75% prevalence of LV hypertrophy despite treated hypertension [24,25,26,27,28]. LV hypertrophy, an LV mass >51 kg/m 2.7 , can be treated by maintaining higher levels of hemoglobin with the use of erythropoietin [41], and by effectively treating hypertension.…”
Section: Non-invasive Assessment Of Cardiac End Organ Injurymentioning
Mortality from end-stage renal disease (ESRD) is often due to cardiac causes. Although cardiovascular complications of ESRD have long been recognized, only recently has the presence of traditional cardiovascular risk factors been associated with late cardiovascular complications. This review presents a history of cardiac involvement in ESRD, the pathophysiology of accelerated atherosclerosis and left ventricular hypertrophy, and a summary of the literature on cardiovascular risk assessment in children. Techniques for non-invasive assessment of cardiac end-organ injury are also discussed. Recommendations for monitoring of risk factors and treatment in the pediatric ESRD population are presented.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
