The study involved 50 normotensive men (means age = 34 years) with diabetes mellitus type I (mean duration of the disease 14 years). Group I included 29 patients with normal albumin excretion with the urine (UAE below 30 mg daily), and group II-21 patients with microalbuminuria (UAE 30-300 mg daily). Both groups were similar in relation to the age and duration of diabetes mellitus. Blood cholesterol was significantly higher in patients of group II than in patients of group I (p = 0.02) similarly to blood triglycerides levels (p = 0.01). Mean arterial pressure was lower in patients of group I than that in patients of group II (94.3 +/- 7.0 vs 99.1 +/- 6.0 mm Hg; p = 0.01). HbA1c was positively correlated with blood cholesterol (p = 0.01) and blood triglycerides levels (p = 0.05).

The purpose of the study was to compare the effect of treatment with an angiotensin converting enzyme inhibitor (Lisinopril, MSD) or calcium blocker (Nifedipine retard, MSD) treatment during three months on blood pressure (measured with sphygmomanometric method and ambulatory blood pressure monitoring--ABPM) and urinary albumin excretion in essential hypertension class I acc. to WHO. Fifteen untreated patients aged 38 +/- 5 years with essential hypertension participated in the study and received diet with normal sodium content. Urinary albumin excretion was measured by RIA method in two 24 hour urine collections and mean value was calculated. ABPM was measured with Spacelabs monitor. After first examination 8 patients were randomly selected for the treatment with lisinopril and 7 patients to the treatment with nifedipine. The doses of both drugs were gradually adjusted to reach diastolic blood pressure below 90 mmHg. After 3 months of treatment urinary albumin excretion and blood pressure was found in both after treatment in patients treated with lisinopril but not in those receiving nifedipine. In patients treated with lisinopril a correlation between the decrease in systolic and diastolic blood pressure (measured by ABPM) and decrease of urinary albumin excretion was demonstrated. It was concluded that the normalization of blood pressure induced by lisinopril treatment in patients with uncomplicated essential hypertension and normoalbuminuria is accompanied with significant diminution of urinary albumin excretion which suggests preventive action of the drug in the development of microalbuminuria. Diminution of urinary albumin excretion caused by lisinopril is probably due to both the decrease of blood pressure and the specific renal action of the drug.

The effect was studied of blood pressure lowering treatment on renal failure and albuminuria (UAE) in patients with type I diabetes (IDDM) and imminent nephropathy as well as in patients with over diabetic nephropathy. The group of 24 patients with imminent nephropathy was subdivided: 1. twelve patients with borderline or overt hypertension with mean BP lowered not below 100 mmHg, and 2. twelve patients with BP within the normal limits, taking no hypotensive agents. In the other group of 12 patients with overt diabetic nephropathy hypertension was lowered below 105 mmHg and kept so for at least two years. All patients estimated their glycemia and glycosuria by themselves, ate 0.8 g protein/kg/24 h and about 100 mmol Na/24h. Under hospital conditions the following were estimated: albuminuria, glomerular filtration rate (51Cr EDTA) and effective renal blood flow (131I hippurate). The same examinations were repeated 1 year and 2 years later. The lowering of BP below 100 mmHg in patients with imminent diabetic nephropathy significantly lowered microalbuminuria without changing GFR, ERPF despite good or satisfactory compensation of diabetes. Maintaining BP below 105 mmHg for 2 years did not prevent the patients with overt nephropathy to develop progressive renal failure despite the rate of GFR deterioration and of the increase of albuminuria slowed down.

The studies included 18 normotensive patients with diabetes mellitus type I (mean age 29 years) and constant microalbuminuria (UAE-30 - 300 mg/24 hours). Group A consisted of 10 patients treated with enalapril, and group B--10 patients given placebo. Glomerular filtration rate, ERPF, and UAE were measured before and after 6 months of therapy. UAE decreased significantly in patients of group A (p = 0.02) after 6 months while evident proteinuria was seen in two patients of group B. Arterial blood pressure dropped in patients of group A (131/84 vs 122/78 mm Hg), and increased significantly in patients of group B (126 +/- 8 vs 136 +/- 15 mm Hg; p < 0.05). Blood flow through kidneys improved (p = 0.02) and renal vascular resistance decreased (p = 0.02) in patients of group A. The obtained results suggest that enalapril may prevent diabetic nephropathy in diabetics with constant microalbuminuria.

The aim of the investigation was microalbuminuria evaluation as an early symptom of renal involvement in systemic lupus erythematosus (SLE). Thirty patients aged 18 to 66 years (mean: 39,4 years) with mean duration of SLE of 6,3 years (range: 0,5 to 22 years) were examined. All of them fulfilled the preliminary criteria of the American Rheumatism Association for the classification of SLE. During the study none of patients had clinical or laboratory symptoms of nephropathy, hypertension, diabetes mellitus and heart failure. Microalbuminuria was measured by immunoturbidimetric method and the urine microalbumin concentration was expressed as the ratio microalbumin-creatinine concentration in 24 hour urine [equation: see text] Ratio I was 3,36 (+/- 2,76) in patients suffering from SLE comparing to I = 1,35 (+/- 0.89) in normal controls (p < 0.001). There was no correlation between increasing microalbuminuria and patients age and duration of disease. There was also no correlation between microalbuminuria and erythrocyte sedimentation rate or immunological activity parameters (i.e. antinuclear antibodies, anti dsDNA antibodies, levels of C3 and C4 components of complement).

The purpose of the study was to assess TGF-beta and IL-6 urinary excretion (measured with EIA) in 12 IDDM patients (7 F, 5 M, age 20-49 yrs, mean = 33.08) with albuminuria or microalbuminuria. Control group consists of 27 IDDM patients (12 F, 15 M, age 24-59 yrs. mean = 39.5) without albuminuria or microalbuminuria. Urinary excretion of IL-6 was significantly higher (p < 0.05) in IDDM patients with albuminuria (mean = 7.43 +/- 8.29 pg/mg creatinine) than in control group (mean = 3.74 +/- 2.64 pg/mg creatinine). Urinary excretion of TGF-beta was also higher (but not significantly in IDDM patients with albuminuria or microalbuminuria (mean = 42.0 +/- 30.0 pg/mg creatinine) than in control group (mean = 27.0 +/- 20.0 pg/mg creatinine). The data indicate that IL-6 and TGF-beta could be involved in the development of diabetic nephropathy.

Microalbuminuria and its associations with vascular disease has been reported in diabetic and non-diabetic individuals. The significance of microalbuminuria in cardiovascular complications is unclear. It has been suggested that microalbuminuria reflects a more generalized pathological process of the vascular system, affecting the glomeruli, retinal vessels and the intimal larger vessels, simultaneously. Microalbuminuria is more prevalent in diabetic, hypertensive and elderly people with risk of vascular complications. Testing for microalbuminuria is recommended for all identifying subgroups with risk vascular complications and premature death. Such program is likely to be cost-effective because of savings in the treatment costs and complications (e.g. renal dialysis and transplantation).

Nephropathy is a frequent complication of long term diabetes. Diabetic nephropathy is the major determinant of premature morbidity and mortality both in insulin-dependent (IDDM) and in non-insulin dependent-diabetes mellitus (NIDDM). There is good evidence that genetic predisposition plays a major role in development of diabetic nephropathy. This hypothesis is based on the observation that diabetic nephropathy clusters within families, both in IDDM and NIDDM. Components of the renin-angiotensin system (RAS) are plausible candidate genes to examine for a association with microalbuminuria and diabetic nephropathy. In this study we compared the distribution of PstI melting polymorphism at the ACE locus among NIDDM patients with diabetic nephropathy and in patients who, despite long duration of NIDDM, remain without this complication. The 220 NIDDM patients for whom DNA was available were classified into two groups according to their renal status: normoalbuminuric control subjects (n = 80) who are NIDDM patients with an A/C ratio < 2.5 and nephropathy cases (n = 140) who are NIDDM patients with A/C ratio > 2.5. Albumin excretion rate was assayed by radioimmunoassay. HbA1c was assayed using HPLC methods, creatinine--using Jaffe methods and DNA analysis using PCR reaction, and then after the amplification product was digested with PstI enzyme. The study revealed that PstI sequence differences ("+/= and -") in the ACE gene do not contribute to genetic susceptibility to diabetic nephropathy in NIDDM.

The study included 65 patients--42 males and 23 females aged 67 +/- 17 with the diabetic foot syndrome. They were divided into 2 groups: those who underwent amputation (25 patients) and 40 who were treated conservatively. Amputations were preceded most frequently by ulceration (17 cases), phlegmona (5 cases) or dry necrosis (3 cases). The high percentage of amputations in the studied patients could be explained, at least in part, by poor general condition and advanced local changes. In the group of patients, who underwent amputation--in relation to those treated conservatively a decrease in filtration function was found (46.0 +/- 24.3 vs 89.5 +/- 26.2) and a higher percentage in the prevalence of microalbuminuria or proteinuria (80% vs 45%) as well as a higher percentage of cigarettes smokers in this group (72% vs 40%). The majority of the studied patients was characterized by poor education, lack of self-control of glycaemia, no efficient metabolic control of diabetes, measured by glycated haemoglobin and the presence of neuropathy and retinopathy. In addition, in 4 patients among the whole studied group (including 1 patient who underwent amputation), diabetes was newly diagnosed. These results indicate the necessity of improving education, early diagnosis of insulin independent diabetes, more frequent foot examinations and the elimination of amputation risk factors. Prophylaxis of diabetes foot associated with the proper treatment of diabetes is a necessary condition for decreasing of the amputation rate according to St. Vincent Declaration.

The purpose of the study was to assess urinary excretion of extracellular matrix proteins and proteolytic enzymes in 12 subjects with IDDM with albuminuria, 12 subjects with IDDM without microalbuminuria and 10 normal healthy subjects. Urinary excretion of FN was significantly higher in subjects with IDDM and albuminuria as compared to patients with IDDM without microalbuminuria and healthy subjects (223.6 +/- 143.2 vs. 103.2 +/- 59.7 vs. 58.3 +/- 12.0 ng/mg creatinine, p < 0.01). Urinary level of type IV collagen was significantly elevated in subjects with IDDM and albuminuria as compared to IDDM without microalbuminuria and healthy subjects of cathepsin B was significantly higher in diabetic patients with albuminuria as compared to patients without microalbuminuria and healthy subjects (0.82 +/- 0.53 vs. 0.25 +/- 0.17 vs. 0.22 +/- 0.05 mlU/mg creatinine, p < 0.01). Urinary activity of plasmin was significantly elevated in diabetic patients with albuminuria as compared to subjects without microalbuminuria and healthy control (0.477 +/- 0.37 vs. 0.194 +/- 0.09 vs. 0.21 +/- 0.02 mlU/mg creatinine, p < 0.01). Our data indicate that increase in the urinary excretion of extracellular matrix proteins may be the useful tool for monitoring glomerular injury.
