[Automated peritoneal dialysis (APD). Experience in 42 patients].

Automated peritoneal dialysis (APD) is currently considered as one of the most attractive home treatments for uremic patients. However, relevant costs and the presence of a dialysis machine prevent a wider diffusion of this technique. In this work we discuss the results obtained in 42 patients (12 females, 30 males) treated by two dialysis units of the Piedmont Region. Patients' characteristics. Eighty-three percent of the females and 66.5% of the males are under 65 years of age; glomerulo-nephritis and nephroangiosclerosis account for the most frequent renal diseases (28.5 each); a high risk condition is recorded in 52.5% of cases. Twenty-two patients were transferred to APD from CAPD (patient's request in 59% of cases, clinical problems in the remaining). RESULTS. Forty-five percent of cases are working full or part-time, 12% are not caring for self. Peritonitis rate accounts for 1 episode every 42 patient-months. Biochemical control is satisfactorily achieved (mean values: urea 137.8 mg/dl, creatinine 11 mg/dl, calcium 10.2 mg/dl, phosphate 5.7 mg/dl, albumin 4.3 g/dl, cholesterol 234 mg/dl, triglycerides 195 mg/dl). Technical assistance was requested on average once every 16 months of treatment. CONCLUSION. Negative drawbacks of APD, mainly related to elevated costs and technical complexity, are fully counterbalanced by satisfactory social and clinical rehabilitation, wider indications to peritoneal dialysis with respect to CAPD, lower rates of peritonitis and limited technical needs.
