We investigated the validity of a one plasma sample method (I) compared with a multiple plasma sample method (II) for routine clinical determination of glomerular filtration rate (GFR) in 35 insulin-dependent diabetic patients suffering from nephropathy. GFR was measured after an intravenous bolus injection of 100 microCi 51Cr-EDTA by determination of plasma radioactivity in venous blood samples taken from the other arm 180, 200, 220 and 240 min after the injection (II). The plasma radioactivity in the sample drawn 240 min after injection was used in method I. During the mean investigation period of 32 months (12-62 months) a total of 184 GFR determinations were performed. The average interval between the GFR measurements was 6 months (1-21 months). In 127/184 of the study intervals method I indicated a decrease in GFR. The corresponding figure for method II was almost identical, 130/184. The mean decline in GFR was 8.1 +/- 7.2 and 7.8 +/- 6.9 ml year-1 1.73 m-2 using methods I and II, respectively (NS). The methods essentially provided the same GFR values in absolute terms (r = 0.98, P less than 0.001). We conclude that the one plasma sample method can be used as a valid routine technique in non-uraemic patients with nephropathy. 相似文献

Summary The aim of this study was to assess the effect of simvastatin on plasma lipoproteins and renal function in hypercholesterolaemic
Type 1 (insulin-dependent) diabetic patients with diabetic nephropathy. Twenty-six hypercholesterolaemic (total cholesterol
≽ 5.5 mmol/l) Type 1 diabetic patients with nephropathy were enrolled in a double-blind randomized placebo-controlled study
for 12 weeks. The active treatment group (n -14) received simvastatin (10–20 mg/day) for 12 weeks while the remaining 12 patients received treatment with placebo. The
results during simvastatin treatment (baseline vs 12 weeks): total cholesterol 6.6 vs 4.8 mmol/1 (p < 0.01), LDL-cholesterol 4.25 vs 2.57 mmol/l (p < 0.01) and apolipoprotein B 1.37 vs 1.06 mmol/l (p < 0.01). HDL-cholesterol, and apolipoprotein A-I remained unchanged. Total cholesterol, LDL-cholesterol, HDL-cholesterol,
apolipoprotein A–I, apolipoprotein B remained unchanged during placebo treatment. Albuminuria measured during the simvastatin
and the placebo treatment (baseline vs 12 weeks) (the data are logarithmically transformed before analysis because of their
positively skewed transformation; geometric mean (×/÷ antilog SE) is indicated) was 458 (×/÷ 1.58) vs 393 (×/÷ 1.61) and 481
(×/÷ 1.62) vs 368 (×/÷ 1.78 μg/min (NS). Glomerular filtration rate during simvastatin and placebo treatment (baseline vs
12 weeks) was 64 vs 63 and 72 vs 74 ml·min−1·1.73 m−2, respectively. Two patients receiving simvastatin treatment were withdrawn, one due to gastrointestinal side effects and
one due to myalgia. In conclusion, our short-term study in Type 1 diabetic patients with diabetic nephropathy did not reveal
any beneficial effect on albuminuria despite a striking lipid-lowering effect of simvastatin in diabetic nephropathy. 相似文献

Summary Progression in diabetic nephropathy is usually determined by repeated measurements of glomerular filtration rate and expressed as rate of decline in glomerular filtration rate. Our aim was to evaluate the agreement between rate of decline in glomerular filtration rate estimated from the Cockroft-Gault formula: (140-age)*K*body weight* (1/S-creatinine) and measured by the plasma clearance of 51CrEDTA. All insulin-dependent diabetic patients with diabetic nephropathy followed-up for at least 5 years with at least 5 simultaneous measurements of glomerular filtration rate, s-creatinine, and weight were included in the study. Forty-three patients (32 male/11 female), age 31 (18–61) years were enrolled. Observation period: 6.6 (5.1–9.9) years and number of investigations per patient 6 (5–16) (median(range)). Baseline glomerular filtration rate (ml/min) was 97 (30) measured and 107 (37) estimated (mean(SD))(p<0.001) and the 95% limits of agreement were –42.0 to 20.8 ml/min. Measured and estimated glomerular filtration rate correlated significantly (r = 0.91, p<0.00001). Rate of decline in kidney function ml · min–1 · year–1 was 4.7 (3.3) measured and 4.8 (3.5) estimated (mean(SD)) (NS), but the 95% limits of agreement showed a wide range –3.9 to 3.5 ml · min–1 · year–1. A significant correlation between rate of decline in measured and estimated glomerular filtration rate was present (r = 0.84, p<0.00001). In conclusion, glomerular filtration rate is overestimated by the Cockroft-Gault formula. The mean rates of decline in glomerular filtration rate are comparable, but the limits of agreement are wide, which make the Cockroft-Gault method unacceptable for clinical purposes, i.e. monitoring progression in kidney function in the individual patient. However, the estimated glomerular filtration rate may be used for comparison of groups in observational studies and in clinical trials with a long observation period.Abbreviations GFR

Summary Renal clearance of 51Cr-EDTA as a measure of glomerular filtration rate was followed prospectively for 21 months in 18 Type 1 (insulin-dependent) patients with juvenile-onset diabetes and nephropathy. Hypertension was treated aggressively, attaining a mean blood pressure of 154/88 mmHg in the supine and 126/82 mmHg in the standing position. The mean glycosylated haemoglobin value (HbA1c) during the observation period was found to correlate well with the mean of random blood glucose values (r=0.72). It also correlated to the rate of glomerular filtration rate decline over time, whether the latter was calculated as slope coefficient for all available data (r=-0.52, p<0.05) or based on the first and last observations only (r=-0.57, p<0.05). In a multiple linear stepwise regression analysis also including mean arterial blood pressure, the correlation between glomerular filtration rate decline and HbA1c was significant at p<0.01; this explained one-third of the progression, while mean arterial pressure could not be shown to contribute. It is concluded that hyperglycaemia, contrary to the general belief, is a risk factor for the progression of clinical diabetic nephropathy with reduced glomerular filtration rate. 相似文献

AIMS: To determine the natural course of kidney function and to evaluate the impact of putative progression promoters in Caucasian Type 2 diabetes mellitus (DM) patients with diabetic nephropathy who had never received any antihypertensive treatment. METHODS: A long-term observational study of 13 normotensive to borderline hypertensive Type 2 DM patients with diabetic nephropathy. Glomerular filtration rate (GFR) was measured approximately every year (51Cr-EDTA plasma clearance technique). Albuminuria, blood pressure (BP) and haemoglobin A1c (HbA1c) was determined 2-4 times per year and serum cholesterol every second year. RESULTS: The patients (12 males/one female), age 56+/-9 (mean +/- SD) years, with a known duration of diabetes of 10+/-6 years, were followed for 55 (24-105) (median (range)) months. GFR decreased from 104 (50-126) to 80 (39-112) ml x min(-1) x 1.73 m(-2) (P = 0.002) with a median rate of decline of 4.5 (-0.4 to 12) ml x min(-1) x year(-1). During follow-up, albuminuria rose from 494 (301-1868) to 908 (108-2169) mg/24 h (P = 0.25), while BP, HbA1c and serum cholesterol remained essentially unchanged. In univariate analysis the rate of decline in GFR did not correlate significantly with neither baseline nor mean values during follow-up of BP, albuminuria, HbA1c and serum cholesterol. CONCLUSIONS: Our study suggests that normotensive to borderline hypertensive Type 2 DM patients with diabetic nephropathy have a rather slow decline in kidney function, but we did not unravel the putative progression promoters responsible for the variation in rate of decline in GFR. 相似文献

The incidence of end-stage renal failure (ESRF) is higher in the Indo-Asian ethnic group as compared to the White. To investigate whether this might be associated with faster rates of progression to ESRF in Indo-Asian diabetic patients, we studied a total of 39 Type 2 diabetic patients, using the Department of Nephrology database showing serial serum creatinine measurements from the time of first referral to the clinic until they reached a level of >500 μmol l−1 or ESRF requiring renal replacement therapy (RRT), either dialysis or renal transplantation. They were grouped into Indo-Asian (n = 24) and White (n = 15). The rate of progression of those who developed ESRF, calculated as the slope of log serum creatinine against time, was not significantly different between the Indo-Asian and White patients, p = 0.73. We conclude that the higher incidence of ESRF in the Indo-Asian Type 2 diabetic patient with nephropathy is therefore not due to a faster rate of deterioration in renal function. © 1998 John Wiley & Sons, Ltd. 相似文献
