The differences of values between any CKD stages were analyzed by ANOVA. Results: In all cases the kidneys shrank and cortical thickness was decreased as well as the brightness of the cortex was

increased significantly in association with the decrease in eGFR. In diabetic CKD patients, however, the correlation was weakened between long axial length of the kidney and eGFR. Moreover, long axial length between stage 3 and 4 did not differ in diabetic CKD patients. Conclusion: The morphometric analysis of kidney ultrasonography was quantitated in the present study, resulting in the close relationship between the changes in morphology and eGFR. In diabetic CKD patients, the kidney sizes are well preserved, providing a clue for the diagnosis of the original disease.

from cardiovascular disease is high in maintenance haemodialysis patients (MHD).There is a greatly increased incidence of sudden death for MHD patients .The QTc interval has been reported to be increased and to be associated

with high-risk ventricular arrhythmias and sudden death. There is a direct evidence that in MHD patients increased effect of arterial wave reflections is an independent predictor of all-cause and cardiovascular mortality. We aimed to evaluate the relationship between QT intervals and pulse wave velocity (PWV) and the risk factors for arterial stiffness in MHD patients. Methods: Eligible 149 MHD patients were enrolled into the study. Electrocardiographic evaluations were performed at the beginning and end of the study. A QTc interval greater than Pregnenolone 440 ms was considered abnormally prolonged. Patients with QTc interval < 440 ms at the beginning and end of the study was defined as Group A(n:48). Patients whose intial QTc interval were >440 ms and/or those whose QTc interval increased >440 at the end of the follow-up were defined as Group B (n:101). PWV were assessed at the beginning and end of the study. Results: Patients in Group B had significantly higher intitial and follow-up PWV values, compared to the patients in Group A (7.9 ± 2.8 m/sn to 8.2 ± 3.4 m/sn vs 6.8 ± 2.7 m/sn to 6.5 ± 2.1 m/sn ) values both at the beginning and end of the study (p2: 0.027, p < 0.045). Additionally administired equivalent vitamin D dose was significantly higher in Group A compared to Group B (4.1 ± 4.7 mcg/week vs 2.7 ± 3.2 mcg/week, p < 0.035).
