The aim of study was to evaluate the influence of the dialysis method and patients knowledge about disease and therapy on the 24 hour blood pressures (BP) values. MATERIAL AND METHODS. The study group consisted of 62 dialysed patients--27 with peritoneal dialysis (PD) and 35 with hemodialysis (HD). The questionnaire including sociodemographic data, information about disease and questions assessing patients knowledge about disease was carried out. Additionally, 24 hour ambulatory blood pressure monitoring (ABPM) and medical record analysis was performed. Results. Patients with PD had lower BP, especially systolic (SBP), than did patients with HD, (p < 0.05). PD patients treated > 3 years were more often non-dippers. The higher SBP (183.3 < or = 34.6 vs 149.9 +/- 18.4 mmHg, p < 0.05), MAP (105.9 +/- 16.7 vs 92.1 +/- 12.6 mmHg, p < 0.05) and BP fluctuations were also observed in HD women in comparison with PD women. Diastolic BP negatively correlated with age of the patients. The level of knowledge about disease was higher in PD patients, however, there was no relationship between knowledge and BP values. There was also no correlation between patients compliance with therapeutic regimen and BP values, although persons who adhered more systematically to the dietician recommendations had advantageous drop's in BP at night (p < 0.05). The results suggest that high BP values and its fluctuations are more often observed in HD patients, especially in females. The influence of patients knowledge and compliance on BP values should be verified by further research.
