Neuropathy and quality of life in diabetic continuous ambulatory peritoneal dialysis patients

Diabetes mellitus is the commonest cause of end-stage renal failure and is associated with considerable morbidity. Neuropathy is one of the most serious complications of diabetes, linked to the incidence of nephropathy and retinopathy. The prevalence of neuropathy increases with age and duration of diabetes. Peripheral sensorimotor neuropathy is the main manifestation of neurological damage in diabetes, while autonomic neuropathy, a devastating complication, is also present in a large number of patients with long-term diabetes. Clinical features of autonomic neuropathy are mainly cardiovascular disorders and abnormal visceral function. One of the most important sequelae of neuropathy is the development of the insensitive foot at risk of ulceration, deformation, Charcot neuroarthropathy, and amputation. Prevention, education, and identification of the at-risk patient are the key elements in managing these severe complications. Dialysis, and mainly peritoneal dialysis, still remains the main renal replacement therapy for end-stage renal disease (ESRD) diabetic patients. It is obvious from many studies that diabetes and its complications are major risk factors associated with poorer survival rates, increased morbidity, and decreased quality of life. Few, if any, data are available specifically evaluating quality of life in continuous ambulatory peritoneal dialysis (CAPD) diabetic patients. Fewer data are available estimating the impact of neuropathy on the quality of life of such patients. Specific studies must be carried out to further investigate quality-of-life issues and neuropathy in this vulnerable group of patients.
