N2 - Background. Plasma N-terminal fragment of pro brain natriuretic peptide (NT-proBNP) concentration is elevated in cardiovascular diseases such as congestive heart failure, where increased levels of NT-proBNP indicate cardiac dysfunction, hypervolemia, and higher risk of hospitalization and death. These associations apply also to patients with severe impairment of kidney function. Little is known about diferences in plasma level of NT-proBNP in patients receiving hemodialysis (HD) versus those receiving continuous ambulatory peritoneal dialysis (CAPD). Aim. To evaluate differences in plasma NT-proBNP concentration between HD and CAPD patients. Methods. Plasma NT-proBNP concentration was prospectively measured in consecutive patients receiving either HD or CAPD at our hospital center. All other standard clinical parameters were recorded. The correlation between plasma NT-proBNP concentration and the type of dialysis was then examined. Results. We studied 99 consecutive patients on HD (age 62 +/- 15 years, 66% male) and 18 consecutive patients on CAPD (age 56 +/- 18 years, 67% male). Both groups had similar baseline characteristics including duration of dialysis, left ventricular function and mass, and cardiothoracic ratio. Significantly more patients on HD had abnormal NTproBNP levels compared to patients on CAPD (97% vs 44%; P<0.0001), and this difference remained highly significant when using various NT-proBNP cut off values. A subgroup analysis revealed that the lower NT-proBNP levels of CAPD patients are most pronounced in patients with preserved left ventricular ejection function. As expected, NT-proBNP levels correlated negatively with left ventricular function and positively with cardiothoracic ratio, and this applied to both HD and CAPD groups. Conclusion. The lower concentration of NT-proBNP in patients on CAPD compared to those on HD suggests that CAPD produces lesser hemodynamic stress, especially in patients with preserved left ventricular systolic function. Even though increased NT-proBNP levels have been shown to predict increased morbidity and mortality, further studies are necessary to assess the long term benefit of CAPD compared to HD.
