    Notes: Summary The Steno hypothesis suggests that albuminuria reflects widespread vascular damage (proliferative retinopathy and severe macroangiopathy) due to a generalized vascular (endothelial) dysfunction. We assessed this concept in NIDDM (non-insulin-dependent diabetic) patients with (13 female/39 male, age 60 ± 7 years, group 1) and without (12 female/41 male, age 61 ± 7 years, group 2) diabetic nephropathy compared to matched non-diabetic subjects (7 female/15 male, age 58 ± 8 years, group 3). A 12-lead ECG was recorded and coded blindly using the Minnesota Rating Scale; the World Health Organization cardiovascular questionnaire was used to assess past and present evidence of myocardial infarction, angina pectoris, stroke, and peripheral vascular disease (digital systolic blood pressure determination). The degree of diabetic retinopathy was scored from fundus photography. The following variables were measured: transcapillary escape rate of albumin (initial disappearance of intravenously injected 125I-labelled human serum albumin), plasma concentrations of prorenin (radioimmunoassay) and serum concentrations of von Willebrand factor (enzyme-linked immunoadsorbent assay). Prevalence of ischaemic heart disease (ECG reading) (49/20/5)% and peripheral vascular disease as indicated by reduced systolic blood pressure on big toe (69/30/14)% was significantly higher in group 1 vs group 2 (p 〈 0.01) and in group 2 vs group 3 (p 〈 0.01), respectively. The prevalence and severity of retinopathy was higher in group 1 vs 2 (p 〈 0.01). Transcapillary escape rate of albumin (%/h) was elevated in group 1 and 2 as compared to control subjects: 7.9 (4.3–13.7); 7.4 (3.7–16.4) vs 6.0 (3.4–8.7), (p 〈 0.005), respectively. Plasma prorenin activity (IU/ml) was raised in group 1 and group 2 as compared to group 3: 272 (59–2405); 192 (18–813), and 85 (28–246), p 〈 0.001, respectively. Serum von Willebrand factor (IU/ml)was elevated in group 1 as compared to group 2 and 3: 2.07 (0.83–4.34); 1.60 (0.30–2.99) and 1.50 (1.00–2.38), p 〈 0.001, respectively. Our study demonstrated that NIDDM patients with and without albuminuria had increased transcapillary escape of albumin and raised prorenin activity, whereas only those with albuminuria had increased von Willebrand factor. Patients with NIDDM may have abnormal endothelial function in the absence of albuminuria. [Diabetologia (1996) 39: 1590–1597]

    Notes: Summary Insulin-dependent diabetic (IDDM) patients with diabetic nephropathy have a highly increased morbidity and mortality from coronary heart disease. An insertion (I) /deletion (D) polymorphism in the angiotensin-I-converting enzyme (ACE) gene has been shown to be associated with coronary heart disease. Therefore, we have investigated the role of this ACE/ID polymorphism in 198 IDDM patients with diabetic nephropathy and 190 normoalbuminuric IDDM patients. The prevalence of myocardial infarction and other coronary heart disease was significantly elevated in patients with nephropathy, 19 % (38/198) vs 8 % (15/190), p 〈 0.001. In the nephropathic group 12 of 63 (19 %), 23 of 95 (24 %), and 3 of 40 (7.5 %) patients with the DD, ID and II genotypes, respectively had a history of coronary heart disease, II vs DD and ID, p 〈 0.05 when compared to nephropathic patients without coronary heart disease. Multiple logistic regression analysis of the risk factors associated with coronary heart disease in univariate analysis revealed that the II genotype acts as an independent protective factor against coronary heart disease, odds ratio II/DD + ID 0.27 (95 % confidence interval 0.07–0.97, p 〈 0.05). There was no difference in genotype or allele frequency (D/I) between patients with and without nephropathy, 0.56/0.44 in both groups, but plasma ACE concentration was elevated in patients with nephropathy 609 (151–1504) ng/ml as compared to patients with normoalbuminuria, 428 (55–1630) ng/ml, p 〈 0.001. We suggest that ACE/ID polymorphism may influence the frequency of life-threatening cardiac complications in IDDM patients suffering from diabetic nephropathy, a condition characterized by increased plasma ACE concentration.

    Notes: Summary Recombinant DNA technology allows the production of insulin analogues with faster absorption rates from subcutaneous tissue as compared to soluble human insulin. The human insulin analogue B10Asp (mono/dimeric) is absorbed twice as fast as soluble human insulin (hexameric). A double blind, randomised crossover study with a 1-month run-in period and two 2-month treatment periods was performed in 21 male insulin-dependent diabetic (IDDM) patients aged 18–40 years in order to compare the metabolic control obtained with equimolar doses of the analogue B10Asp vs soluble human insulin (Actrapid) given as mealtime insulin and intermediate acting isophane insulin (Protaphane) at bedtime. At the end of each 2-month study period, the patients were admitted to the metabolic ward. We found significantly higher plasma insulin/analogue levels after breakfast, lunch and dinner with B10Asp as compared to Actrapid (p 〈 0.05). The plasma insulin/analogue levels were significantly lower before lunch and dinner with B10Asp as compared to Actrapid (p 〈 0.05). Also, the plasma insulin/analogue level tended to be lower at bedtime when comparing B10Asp to Actrapid. The 24-h blood glucose profiles showed identical fasting blood glucose, significantly lower blood glucose after breakfast with the analogue (p 〈 0.05), no differences in blood glucose after lunch and dinner but a significantly higher blood glucose at midnight using the analogue (p 〈 0.05). The overall 24-h mean blood glucose concentrations, the daily insulin dose, HbA1 c, diet, home blood glucose monitoring and frequency of hypoglycaemia were almost identical in the two treatment periods. In conclusion, the overall glycaemic control remained unchanged and quite good when Actrapid was exchanged dose for dose with the insulin analogue B10Asp in IDDM patients treated with a basal bolus regime.

    Notes: Summary Glomerular hyperfiltration and microalbuminuria are both regarded as risk factors for the development of diabetic nephropathy in insulin-dependent diabetic patients. Information on glomerular hyperfiltration is scarse in microalbuminuric non-insulin-dependent diabetic (NIDDM) patients. Therefore, we performed a cross-sectional study of glomerular filtration rate (single i. v. bolus injection of 51Cr-EDTA, plasma clearance for 4 h) in 158 microalbuminuric NIDDM patients compared to 39 normoalbuminuric NIDDM patients and 20 non-diabetic control subjects. The groups were well-matched with regard to sex, age and body mass index. The uncorrected (ml/min) and the adjusted (ml · min–1· 1.73 m–2) glomerular filtration rate were both clearly elevated in the microalbuminuric patients: 139 ± 29 and 117 ± 24 as compared to 115 ± 19 and 99 ± 15; 111 ± 23 and 98 ± 21 in normoalbuminuric NIDDM patients and control subjects, respectively (p 〈 0.001). The glomerular filtration rate (ml · min–1· 1.73 m–2) in NIDDM patients who had never received antihypertensive treatment was also clearly elevated in the microalbuminuric patients (n = 96): 119 ± 22 as compared to 100 ± 14 and 98 ± 21 in normoalbuminuric NIDDM patients (n = 27) and control subjects (n = 20), respectively (p 〈 0.001). Glomerular hyperfiltration (elevation above mean glomerular filtration rate plus 2 SD in normoalbuminuric NIDDM patients) was demonstrated in 37 (95 % confidence interval 30–45)% of the microalbuminuric patients. Multiple regression analysis revealed that HbA1 c, 24-h urinary sodium excretion, age and known duration of diabetes were correlated with glomerular filtration rate in microalbuminuric NIDDM patients (r 2 = 0.21, p 〈 0.01). Our cross-sectional study indicates that NIDDM patients at high risk of developing diabetic nephropathy are also characterized by an additional putative risk factor for progression, glomerular hyperfiltration.

    Notes: Summary The increased mortality of patients with diabetic nephropathy is mainly due to cardiovascular disease and end stage renal failure. Left ventricular hypertrophy is an independent risk factor for myocardial ischaemia and sudden death. The aim of our cross-sectional study was to evaluate left ventricular structure and function in Type I (insulin-dependent) diabetic patients with diabetic nephropathy. M-mode and Doppler echocardiography were done on 105 Type I diabetic patients with diabetic nephropathy [61 men, age (means ± SD) 44 ± 9 years, and albuminuria [median(range)] 567(10–8188) mg/24 h, serum creatinine 109 (53–558) μmol/l], and 140 Type I diabetic patients with persistent normoalbuminuria [79 men, 47 ± 10 years, urinary albumin excretion rate 8 (0–30) mg/24 h, and serum creatinine 81 (55–121) μmol/l]. Patients with and without nephropathy were comparable with respect to sex, body mass index, and duration of diabetes. Arterial blood pressure was slightly higher in patients with nephropathy: 140/79 ± 17/9 mm Hg vs 134/78 ± 15/8 mm Hg, p 〈 0.01, and the majority of proteinuric patients received antihypertensive drugs, 84 vs 17 %, respectively, p 〈 0.001. Left ventricular mass index was increased in the nephropathic group (means ± SD) 100.6 ± 23.9 g/m2 compared with the normoalbuminuric group 91.4 ± 21.9 g/m2, p = 0.002. Left ventricular hypertrophy was found more often in patients with nephropathy 23 (14–31)% compared with patients with normoalbuminuria 9 (5–14)%, p 〈 0.005. Diastolic function, assessed by the ratio between the peak diastolic velocity and the peak atrial systolic velocity (E/A ratio) and isovolumic relaxation time, was reduced in patients with vs without nephropathy: 1.17 ± 0.29 vs 1.34 ± 0.32, and 81.7 ± 16.5 vs 74.6 ± 14.5, p 〈 0.001 and p = 0.002, respectively. Systolic function was about the same and normal in both groups. Our study suggests that an increase in left ventricular mass index and a decrease in diastolic function occurs early in the course of diabetic nephropathy. [Diabetologia (1999) 42: 76–80]
