To investigate whether persistent microalbuminuria is related to altered levels of both lipids and apolipoproteins in Type 2 diabetes mellitus serum total-cholesterol, triglycerides, HDL-cholesterol, LDL-cholesterol, apolipoprotein A-I, and apolipoprotein B were measured by standard methods in a group of Type 2 diabetic patients affected by persistent microalbuminuria (albumin excretion rate (AER) 20-200 micrograms min-1) as compared with a group of sex- and age-matched non-microalbuminuric patients (AER less than 20 micrograms min-1). The groups were stratified according to a short (less than or equal to 5 years) or a longer (greater than 5 years) duration of diagnosed diabetes. Microalbuminuria was not associated with significant changes of serum total-cholesterol, triglycerides, HDL-cholesterol, LDL-cholesterol, and apolipoproteins in the group of patients with a duration of disease greater than 5 years, while microalbuminuric patients less than or equal to 5 years from diagnosis (n = 11) had serum total-cholesterol, triglycerides, LDL-cholesterol, and apoprotein B higher than non-microalbuminuric control patients (n = 26) (cholesterol 6.2 +/- 0.9 vs 5.1 +/- 1.0 mmol l-1 (p = 0.003); triglycerides 2.1 +/- 0.7 vs 1.7 +/- 1.3 mmol l-1 (p = 0.03); LDL-cholesterol 4.1 +/- 0.8 vs 3.0 +/- 0.7 mmol l-1 (p less than 0.001); apo-B 1.3 +/- 0.3 vs 1.1 +/- 0.3 g l-1 (p = 0.02). In these patients with shorter duration of diabetes many of the serum lipid measures correlated positively with AER.

Coagulation-fibrinolytic system is known to be one of the exacerbating factors in patients with diabetic nephropathy. The aim of the present study was to evaluate whether coagulation-fibrinolytic system in patients with diabetic nephropathy were significantly correlated with the development of this disease using new parameters of plasma thrombin antithrombin III complex (TAT) and plasmin alpha 2 plasmin inhibitor complex (alpha 2PIC). Fifty-six patients with NIDDM were examined. None of these patients showed more than 1.3 mg/dl of serum creatinine levels. These patients were divided into three groups according to the levels of albumin creatinine ratio (ACR) in urine as follows: 1) group I had ACR of less than 30 mg/g.Cr; 2) group II had ACR of greater than 30 mg/g.Cr and less than 100 mg/g.Cr; 3) group III had ACR of greater than 100 mg/g.Cr. Correlations of levels of plasma TAT and alpha 2PIC, levels of HbAlc, duration of diabetes, and presence of retinopathy were determined in these groups. The levels of plasma TAT and alpha 2PIC increased as the levels of urinary ACR increased regardless of presence of retinopathy. The levels of TAT and alpha 2PIC with retinopathy increased compared with those without retinopathy. There was a significantly positive correlation between plasma TAT and alpha 2PIC (r = 0.52, p less than 0.01). The levels of HbAlc and duration of diabetes did not significantly correlate to plasma TAT and alpha 2PIC. These data suggest that the existence of increase in coagulation-fibrinolytic system seem to be one of the exacerbating factors in patients with diabetic nephropathy.(ABSTRACT TRUNCATED AT 250 WORDS)

The effect of a blood pressure reduction by 10 mg extended release felodipine once daily on urinary albumin excretion (UAE) as well as the possible diabetogenic effect of felodipine was studied. A 2 X 12 week placebo-controlled double-blind crossover study was performed in 12 hypertensive non-insulin-dependent diabetic (NIDDM) patients without nephropathy on concomitant treatment with beta-blocker and/or a diuretic agent. Metabolic control as estimated by fasting plasma glucose, hemoglobin A1c and fasting plasma C-peptide was unaltered after felodipine. Blood pressure was significantly reduced by felodipine: systolic 166 +/- 26 mm Hg (placebo) v 153 +/- 26 mm Hg (felodipine) (P less than .05) and diastolic 95 +/- 7 mm Hg v 90 +/- 8 mm Hg (P less than .05). Heart rate was unchanged. There was no correlation between blood pressure and UAE, but the relative change in UAE expressed as UAE placebo/UAE felodipine was significantly correlated to the fall in systolic blood pressure (r = 0.64, P = .03) and mean blood pressure (r = 0.66, P = .02). Since microalbuminuria predicts proteinuria and reduced survival, early antihypertensive treatment may be beneficial in NIDDM as it is in IDDM. Long-term consequences on kidney function and mortality remains, however, to be elucidated.

We evaluated the effect of glycated albumin on phenytoin protein binding in 36 elderly (age range 63-94 yrs) patients with type II diabetes mellitus (DM) under diet management. Serum was spiked with 15 mg/L phenytoin and incubated. A serum ultrafiltrate was obtained from each sample for determining total and free phenytoin concentrations. Glycated hemoglobin was determined by boronate-affinity chromatography, and glycated albumin was separated from nonglycated fractions with boronate-agarose gel. Glycated hemoglobin in the study group ranged from 4.3-14.6% (mean 7.8 +/- SD 2.1%) and glycated albumin ranged from 3.7-12.5% (7.4 +/- SD 2.6%). We observed no correlation between glycated albumin and the percentage of free phenytoin (r2 = -0.14; p = 0.419). The concentration of nonglycated albumin ranged from 0.66-4.28 g/dl (mean 3.45 +/- 0.67 g/dl) and was calculated from measured total and glycated albumin concentrations. A correlation between the free fraction of phenytoin and nonglycated albumin was not demonstrated (r2 = 0.22, p = 0.22). In addition, a correlation was not observed between total glycated albumin and the free fraction of phenytoin (r2 = -0.095; p = 0.58). We conclude that elderly patients with type II DM under diet control do not have significant alterations in phenytoin protein binding. The use of total serum phenytoin levels therefore appears appropriate for determining phenytoin dosages in elderly patients with well controlled type II DM.

The relationship between microalbuminuria and retinal vessel responses to sustained handgrip contraction was studied in a group of 20 diabetic patients. The diabetics were divided into two groups based on their albumin excretion rates (AER): Group 1 (AER less than or equal to 10 mcg/min) consisted of ten diabetic patients, mean age 55.8 +/- 3.9 years (mean +/- SEM); five IDDM and five NIDDM. Group 2 (AER greater than 10 mcg/min) comprised ten diabetic patients: mean age 56.8 +/- 3.04 years; six IDDM and four NIDDM. Both groups were similar in that there were no significant differences between mean age, type of diabetes, mean duration of diabetes, glycaemic control or mean resting blood pressures. Group 2 diabetics had a higher incidence of autonomic dysfunction than Group 1, based on the results of four standard tests of autonomic nerve function. There were significantly decreased retinal vessel responses to sustained handgrip contraction in Group 2 diabetics (mean arteriolar constriction 0.1 +/- 0.32%, and mean venule constriction 1.0% +/- 0.99%) compared with Group 1 diabetics (mean arteriolar constriction 6.9 +/- 1.69%, and mean venule constriction 4.2 +/- 0.05%). Retinopathy was slightly worse in Group 2. The implications of the association of microalbuminuria (AER greater than 10 mcg/min) and loss of retinal vessel reactivity to sustained handgrip contraction are discussed.

This investigation was performed in 15 adult patients: 6 with type I and 9 with type II diabetes mellitus, all with arterial hypertension. Captopril (12.5 to 100 mg daily, mean 34 mg) was administered for a month and was effective as monotherapy in all patients. The supine arterial pressure changed from: 177 +/- 19 mm Hg to 141.7 +/- 7.7 mm Hg systolic and 106 +/- 7.6 mm Hg to 87.3 +/- 5.3 mm Hg diastolic; and upright: from 162.7 +/- 16 mm Hg to 139 +/- 11.4 mm Hg systolic and from 101.7 +/- 11.6 mm Hg to 87.3 +/- 6.5 mm Hg diastolic. The differences were statistically significant (p less than 0.001). The mean blood glucose was changed significantly at the end of the study (from 11.1 +/- 3.4 mmol.l-1 to 8.1 +/- 1.0 mumol.l-1, p less than 0.001), while the daily insulin dose (respectively glybenclamide) remained unchanged. No alterations in serum creatinine, HbA1 (glycohemoglobin), urinary excretion rate of albumin, beta 2-microglobulin, glomerular filtration rate were observed during follow-up. No important change in plasma aldosterone was found, while plasma renin activity was significantly increased (p less than 0.05) as expected. No side effects were reported during the therapy. Captopril appears to be an effective and safe drug for lowering blood pressure in diabetic patients without affecting renal function.

Nine outpatients with mild to moderate arterial hypertension, type 2 diabetes mellitus and persistent macroalbuminuria were studied. After 1 month of placebo, the patients were treated with 50 mg captopril twice a day for the following 6 months. Blood pressure and urinary albumin excretion were significantly reduced but no relationship was found between these two variables. No changes were detected in the renal plasma flow, glomerular filtration rate, filtration fraction, renal vascular resistance or metabolic pattern. Captopril significantly reduced blood pressure and albuminuria without any change in the renal function. The decrease in albuminuria may be related to the reduction in blood pressure as well as to a direct effect of captopril on glomerular haemodynamics.

The serum fructosamine concentration indicates the degree of glycation of serum proteins, particularly albumin, and reflects an average blood glucose level over the previous 1-3 weeks. Serum fructosamine, glycated haemoglobin (HbA1c), total serum protein, serum albumin, fasting plasma glucose and oral glucose tolerance test (OGTT) have been measured in 127 healthy control subjects, 102 type 1 and 152 type 2 diabetes mellitus patients and 106 nondiabetic pregnant women. Fructosamine concentration of 2.24 +/- 0.16 and 3.21 +/- 0.41 mmol/l (mean +/- S.D.) has been found in control subjects and diabetics respectively (P less than 0.001). During the second trimester a significantly lower fructosamine level (1.92 +/- 0.21 mmol/l) has been found in pregnant women, most likely due to the low serum albumin concentration (31.35 +/- 3.97 g/l). None of them had a fructosamine level above the normal limit of 2.55 mmol/l. On the other hand, 12 pregnant women showed a disturbed OGTT with normal fructosamine. If the serum fructosamine concentration was adjusted for 40 g/l albumin, then a mean fructosamine of 2.16 +/- 0.24 mmol/l was found in patients with gestational diabetes. Our results show that serum fructosamine has a similar diagnostic value as HbA1c for non-pregnant adults, but neither can replace OGTT for the diagnosis of gestational diabetes.

Non-insulin-dependent diabetes mellitus is strikingly common in British Indians, but their susceptibility to diabetic complications is unknown. The ratio of albumin to creatinine concentrations was measured in samples of the first urine voided in the morning in 154 Indian and 82 Europid patients with non-insulin-dependent diabetes and in a control group of 129 non-diabetic Indians. The ratio was significantly higher in the Indian patients than in the Europid patients and the Indian controls. There were no significant correlations between the logarithm of the albumin: creatinine ratio and age, known duration of diabetes, haemoglobin A1 concentration, or body mass index within either diabetic group. Hypertension and raised albumin:creatinine ratio were significantly associated, and significant correlations were seen between the logarithm of the albumin:creatinine ratio and systolic and diastolic blood pressures in the Indian but not the Europid diabetics. Because of the high prevalence of diabetes at a relatively early age in Indians, nephropathy may emerge as an important clinical problem.

Fasting plasma zinc levels were determined in 45 IDDM and in 40 NIDDM patients. Mean values were similar in both groups, but diabetic men showed a significantly higher plasma zinc (p less than 0.05) than diabetic women. In patients with diabetic nephropathy a lower zinc level was associated with decreased plasma albumin as compared to patients without complications (p less than 0.001). Neuropathy and macro-angiopathy were also associated with lower zincemia (p less than 0.05) but in the presence of normal albumin levels. In IDDM without nephropathy a significant positive correlation was found between plasma zinc and plasma glucose, albumin, branched chain amino acids and glutamine, while in NIDDM without nephropathy a significant positive correlation exists between plasma zinc and the amino acids glutamine, valine, histidine and lysine.
