  • Title: [Changes in blood pressure, proteinuria and renal hemodynamics in type I diabetes with manifestations of diabetic nephropathy after 2 months of captopril therapy].

    Abstract:
    In 15 type I diabetics with manifest diabetic nephropathy the authors investigated the antihypertensive and antiproteinuric effect of captopril and in seven patients of this group also its effect on renal haemodynamics. Captopril treatment or its combination with hitherto used antihypertensive treatment was associated after two months with a significant drop of the systolic and diastolic blood pressure from 150/95 (120/70-195/110) to 130/90 (110/65-180/115) mmHg, (p < 0.005 < 0.05). The median aortic pressure declined from 118.5 (92-140.8) to 106.5 (84-1334.8) mm Hg (p < 0.005). Nine of 11 patients (82%) could be changed to reduced antihypertensive therapy. The antiproteinuric effect was manifested in 11 patients (73%). Quantitative proteinuria dropped from 2.7 (0.83-8.65) to 1.85 (0.38-8.84) g/24 h., (p < 0.05) without a significant change of serum creatinine: 109 (70-342) vs. 135 (90-288) mumol/l, p = n.s.). The change of proteinuria, as compared with the baseline value, was -41 (-77 - +88)%, (p < 0.05) and did not correlate with the change of the median aortic pressure (correlation coefficient = -0.165, p = n.s.). In the group of seven patients the change of the median aortic pressure was -15% (-26.1 - +6.6), (p < 0.05). No statistically significant change of glomerular filtration was observed: 0.96 (0.32-1.38) vs. 0.96 (0.19-1.71) ml/s, p = n.s.); effective renal plasma flow: 6.32 (2.24-7.74) vs. 7.22 (1.68-10.55) ml/s, (p = n.s.); filtration fraction: 0.136 (0.123-0.220) vs. 0.130 (0.110-0.236), change 0.0 (-43.0 - +31.0)% (p = n.s.) and renal vascular resistance: 15429 (12907-54148) vs. 13243 (7099-77832)%, (p. = n.s.).(ABSTRACT TRUNCATED AT 250 WORDS)
