In this study we compare some demographic and epidemiological characteristics of hemodialysis and peritoneal dialysis patients in an attempt to analyze this issue.
Methods: The results of the research protocol "A survey of the epidemiological characteristics of chronic dialyzed patients in Khorassan province", was used to compare some demographic and epidemiological aspects of chronic hemodialysis and peritoneal dialysis patients in search of any statistically significant difference.
Results: A total of 836 chronic dialysis patients entered this study, 802 (95.9%) of which were under chronic hemodialysis, and 34 (4.1%) patients were undergoing peritoneal dialysis, with 339 (42.3%) and 12 (35.3%) being female, respectively. The mean age for each group was 47.57 and 46.75 years, respectively. The causes of end-stage renal disease in hemodialzed patients were most commonly hypertension (32.2%), followed by diabetes mellitus (22.3%), unknown causes (19.6%) and chronic glomeru-lonephritis (10.2%). In the peritoneal dialysis group, chronic glomerulonephritis (32.4%) was the most common reason for dialysis, followed by diabetes mellitus (26.5%) and unknown causes (11.8%). The mean serum hemoglobin creatinine, calcium, and phosphorus levels for hemodialysis patients were 10.42, 8.5, 8.93, and 6.03 mg/dL, respectively, and those for peritoneal dialysis patients were 11.28, 8.52, 9.41 and 5.40 mg/dL. There were no statistical differences between the median age, sexual distribution and mean levels of Hgb, Ca, phosphorus, creatinine, HCV antibody and HbsAg of the hemodialysis patients and those of the peritoneal dialysis patients.
Conclusions: The results of our study show that hemodialysis and peritoneal dialysis are similarly effective treatments.
