    Notes: Summary Arterial hypertension and poor glycaemic control are central to the development of microalbuminuria in insulin-dependent diabetes mellitus (IDDM). Recent consensus has established sensitive criteria for their detection and treatment, although the proportion of patients who may benefit is unclear. Between 1988 and 1990, we measured urinary albumin to creatinine concentration ratio (A/C) in 3,636 adult out-patients with IDDM of more than 3 years duration, serum creatinine under 133 Μmol/l and who were not undergoing antihypertensive treatment. A/C indicating microalbuminuria (≥2.38/ 2.96 mg/mmol, male/female) was found in 620 of 3,451 patients without proteinuria, and associated with hypertension (blood pressure ≥140 and/or 90 mm Hg; p=0.0016; rate: 39.6%), independent of diabetes duration (p=0.0082) and male gender (p=0.0350; relative risk=1.16; 95% confidence interval: 1.01–1.32). Hypertension was less common among those with normal A/C (27.5%, p〈0.0001) but was positively related with diabetes duration. Of the 1,015 patients with A/C〉2.0 mg/mmol 529 were reexamined. Glycated haemoglobin levels exceeded 3 SD above the mean of normal in 84.3% of the 198 microalbuminuric patients (AER=20–200 Μg/min), but were comparably poor (79.2%) in normoalbuminuria. Duration of diabetes was inversely related to glycated haemoglobin only in microalbuminuria (0.05〈p〈0.1). Intervention to lower blood pressure remains mainly restricted to those patients with long-term diabetes and slower development of kidney disease. Near-normalisation of glycaemia remains the priority for the majority of patients with microalbuminuria.

    Notes: Summary The aim of this study was to evaluate whether long-term glucose control, as assessed by fasting plasma glucose determinations during 3 years, is a predictor of all-cause mortality in elderly NIDDM patients. Five hundred and sixty-six NIDDM patients attending the Verona Diabetes Clinic, aged 75 years and over, were followed-up from 1 January 1987 to 31 December 1991 to assess all-cause mortality. From their clinical records all fasting plasma glucose determinations available for the years 1984 to 1986 were collected and analysed. Patients were grouped in tertiles according to mean (M-FPG), coefficient of variation (CV-FPG) and trend over time (slope, S-FPG) of fasting plasma glucose during the period of retrospective evaluation. Mortality was assessed by observed/expected ratios, univariate Kaplan-Meier survival analysis and multivariate Poisson regression model. By 31 December 1991, 61 men and 127 women had died. Increased observed/expected ratios were found in women from the top M-FPG tertile, in patients (men and women) from the top CV-FPG tertile and in patients with a S-FPG less than –0.30 mmol/l per year (lowest tertile). Patients in the lowest tertile of CV-FPG and in the middle tertile of S-FPG had a reduced mortality risk. Kaplan-Meier survival analysis indicated that patients with high CV-FPG as well as those in tertiles I and III of S-FPG (i.e., those with a definitely negative or definitely positive slope) had an increased probability of dying, without any significant differences between the three tertiles of M-FPG. Poisson regression model showed that CV-FPG, but not M-FPG or S-FPG, was an independent significant predictor of mortality. These results suggest that glucose stability needs to be considered along with the absolute level of metabolic control when treating elderly NIDDM patients. [Diabetologia (1995) 38: 672–679]

    Notes: Abstract The effects of the angiotensin-converting enzyme lisinopril were compared with those of the calcium antagonist nifedipine in 162 non-insulin-dependent diabetic hypertensive patients for a 24-week period. In 83 and 79 patients, respectively, lisinopril and slow-release nifedipine produced similar reductions in blood pressure (systolic/diastolic: −16/−13 mmHg supine and −14/−11 mmHg standing after lisinopril; −15/−12 mmHg supine and −14/−11 mmHg standing after nifedipine). Fasting and post-prandial plasma glucose, glycosylated haemoglobin and plasma lipids appeared to be unaffected by either agent. Also, 28% of the patients on lisinopril and 30% of those on nifedipine presented microalbuminuria. Both drugs induced a reduction in the albumin excretion rate (AER). The geometric meanxx: tolerance factor of the reduction in AER among the 23 microalbuminuric patients on lisinopril (−10.0xx:1.3 μg/min) was greater, though not significantly so, than that observed in the 26 on nifedipine (−0.9x:1.2 μg/min). Moreover, lisinopril appeared to be better tolerated than nifedipine in our study population. Microalbuminuria is an important risk factor for cardiovascular mortality in non-insulin-dependent diabetic patients as well as in the general population. To what extent a reduction in the AER could ameliorate the cardiovascular prognosis in non-insulin-dependent diabetic patients is, at present, unknown. Finally, both lisinopril and nifedipine showed a similar antihypertensive effect in these patients which was not associated with significant differences in plasma glucose, insulin or lipid concentrations. The clinical consequences of the insignificant differences in AER remain unclear.

    Prevalence of hypertension and microalbuminuria in adult type 1 (insulin-dependent) diabetic patients without renal failure in Italy. I. Validation of screening techniques to detect microalbuminuria (1992)

    Notes: Abstract The prevalence of microalbuminuria and arterial hypertension among type 1 (insulin-dependent) diabetic patients is poorly known in Italy. In the preliminary phase of a large outpatient screening programme, we addressed the possibility of using non-time urine samples to predit the chance of detecting albumin excretion rate (AER) in the range of microalbuminuria. We therefore measured urinary albumin and creatinine concentration in timed overnight collections from 641 type 1 diabetic patients with serum creatinine levels lower than 133 μmol/l. AER was strongly and comparably predicted both by urinary albumin concentration (UAlb;r 2=0.754) and by the urinary albumin to creatinine concentration ratio (A/C;r 2=0.773). After exploring several independent cut-off levels for UAlb and A/C, AER in the range 20–200 μg/min (n=91) was found to be predicted with 90% sensitivity and specificity either by UAlb≧20 mg/l or by A/C≧2.0 mg/mmol. UAlb was negatively associated with diuresis, and false negative outcomes were explained by polyuria when screening by this variable. A/C was positively associated with female gender among normoalbuminuric patients, in line with the lower urinary excretion of creatinine in women (7.2±0.25 vs 10.2±0.35 μmol/min,P〈0.00001). A significant excess of false positive outcomes in women compared with men was found when screening by any A/C cut-off level equal to or less than 2.5 mg/mmol. Simplified screening techniques seem to remain, however, a practicable option for the detection of microalbuminuria both in epidemiology and in clinical practice.
