Although the survival of diabetic peritoneal dialysis (PD) patients has
improved, it is still much worse than the survival of nondiabetic patients.
Diabetes has its own risks for cardiovascular disease (CVD), such as increased
levels of advanced glycation end-products, carbonyl and oxidative stress, and
low-grade inflammation. An independent, graded association has been observed
between a reduced glomerular filtration rate and the risk of CVD events in
chronic kidney disease (CKD). Both CKD and diabetes synergistically lead to a
high risk of CVD. It seems that the poor survival of diabetic PD patients is
predestined at the initiation of dialysis because of multiple pre-existing
risk factors and comorbid diseases, particularly CVD.
Recently, several trials were successful in improving the survival of
patients with diabetic CKD. Tight control of glucose, blood pressure
management using angiotensin converting-enzyme inhibitors or angiotensin II
receptor blockers, and use of statins, antioxidants, or peroxisome
proliferator-activated receptor gamma agonists may improve the survival of
diabetic PD patients. However, simple correction of a single CVD risk factor
is not likely to be effective. New PD solutions such as those low in glucose
degradation products or those with icodextrin may also be effective in
reducing the risk of CVD in diabetic PD patients. Therefore, multifactorial
interventions—including diet control, early referral, and choice of an
optimal PD solution—may improve the survival of diabetic PD
patients.
