Treatment of non-insulin-dependent diabetes mellitus patients with nephropathy of the nephrotic type using 40 micrograms prostaglandin E1 given intravenously twice daily for 4 weeks reduced the urinary protein concentration. Prostaglandin E1 also increased the total serum protein and serum albumin concentrations, and reduced creatinine clearance and plasma renin activity following frusemide loading. Treatment with the prostaglandin did not, however, significantly affect the blood urea nitrogen and the serum creatinine concentration. It is concluded that prostaglandin E1 has overt effects on diabetic nephropathy.

We investigated the relationship of serum protein glycosylation to peripheral tissue membrane glycosylation. We studied 27 Sprague-Dawley rats and induced diabetes in 20 of them. Blood glucose levels were treated in 10 of the diabetic animals with daily subcutaneous insulin. After 8 wk, liver and kidney tissue was removed, purified membranes were prepared, and the percentage of glycosylated membrane protein was determined for the liver and kidney membranes by boronate-affinity methods. The percentage of glycosylated membrane protein for both liver and kidney tissue was found to correlate significantly with the glycemic state of the animal as assessed with glycosylated serum albumin, total glycosylated serum proteins, and glycosylated hemoglobin determinations (P less than 0.001 for each glycosylated protein parameter). In addition, the percentage of glycosylated membrane protein in the liver tissue correlated significantly with the measured level in the corresponding kidney tissue (r = 0.78, P less than 0.001). To identify the nature of the glycosylated membrane proteins, boronate-affinity methods were used to separate the glycosylated and nonglycosylated membrane proteins. It was determined that two major glycosylated protein bands exist for the liver membrane (78,000 and 58,700 Mr) and four for the kidney membranes (ranging from 48,700 to 74,000 Mr). The ultrastructural location and identification of these glycosylated membrane proteins are not known. This study demonstrates that measurement of clinical glycemic state, as reflected in glycosylated blood protein parameters such as glycosylated serum albumin and glycosylated hemoglobin, correlates significantly with ongoing tissue membrane accumulation of glucose.

The mean values of body mass index, haemoglobin A1, serum protein, total lipids, triglycerides, lactate dehydrogenase, alkaline phosphatase, amylase and beta-glucuronidase and heart rate and blood pressure and blood urea levels of Libyan diabetic patients with secondary complications are significantly higher than those of the patients without secondary complications. However, the mean values of fasting blood glucose, serum cholesterol and beta-N-acetylglucosaminidase of patients without complications are higher than those of the patients with secondary complications. The duration of diabetes in patients with secondary complications was 10.2 +/- 1 years while that of patients without complications was 5.2 +/- 0.65 years. The significance of these results is discussed.

Used 24-hr recall interviews to assess adherence in a sample of seventy-eight 6- to 19-year-olds with insulin-dependent diabetes mellitus over a 3-month period. Thirteen adherence measures were quantified and grouped into six adherence factors (Injection, Exercise, Diet Type, Testing/Eating Frequency, Calories Consumed, and Concentrated Sweets). Prevailing glucose levels over a 2- to 3-month interval were indexed by glycosylated hemoglobin A1c (HA1c) and glycosylated serum protein (GSP) assays. Fasting triglycerides (TRIG) and total cholesterol (CHOL) assays were used to estimate lipid metabolism. Adolescents were generally less adherent than their young counterparts. Using hierarchical multiple-regression techniques, HA1c and GSP were not reliably predicted by most of the adherence factors; only Calories Consumed showed any predictive power. No significant regression equations emerged for CHOL. In contrast, TRIG was significantly associated with five of the six adherence factors; in all cases, adherence interacted with the patients' metabolic status (as defined by HA1c) at study entry, suggesting that adherence had different effects for youngsters in good versus poor diabetes control.

To evaluate serum fructosamine as an indicator for diabetic control, serum fructosamine (FRA), glycosylated hemoglobin (HbA1c) and fasting plasma glucose (FPG) were simultaneously measured in 452 diabetics in stable diabetic control. We divided the measured FRA according to the degree of deviation from the expected FRA into three types, hyper-FRA, normo-FRA and hypo-FRA. In the hypo-FRA to HbA1c group, frequencies of male (70 vs 35, 43%) and of nephropathy (61 vs 30, 18%) were higher and mean total serum protein (6.5 vs 7.4, 7.4 g/dl) and albumin (3.4 vs 4.1, 4.0 g/dl) were lower than those in the other two corresponding groups. Correlation was also poorer in the insulin-treated group than the others. These results probably reflect conditions of diabetic control and complication, and protein metabolism. Similar tendencies were observed in case of FPG. Therefore, the discrepancy of FRA gives a clue to detect poor control and complications of diabetes.

A group of 548 patients was analyzed retrospectively to determine risk factors, particularly the perioperative administration of blood, for postoperative septic complications after intra-abdominal operations. Of the entire group, 198 (36.1 per cent) had at least one complication. The postoperative mortality rate was 0.9 per cent. Using univariate analysis, blood transfusion, serum protein concentration, gastric malignant disease, total gastrectomy, anastomotic dehiscence, diabetes mellitus, the surgeon and perioperative antibiotics were significant factors influencing the rate of postoperative septic complications. After adjustment for all these factors, logistic regression analysis was used to study the effect of perioperative blood transfusion. Age, serum protein concentration, antibiotics, extended malignant disease of the colon, gastric operation, total colectomy, operation performed by staff members and anastomotic dehiscence were significant independent factors. Blood transfusion per se was not significant (p = 0.07). In patients who received more than 3 units of blood, the postoperative septic complication rate was significantly elevated (p = 0.003). We conclude that the perioperative administration of blood may negatively influence the risk of developing postoperative septic complications after intra-abdominal operations.

For the purpose of improving disturbances of the immunosystem 188 plasmaphereses were carried out in 64 patients. This reports deals with the results of 85 therapeutic plasmaphereses in 39 patients with rheumatoid arthritis, diabetes mellitus, and neurodermatitis or pregnant women with rhesus antibodies for diminishing antibody titres. The Soviet equipment of the type RK-0.5, PF-0.5 and FK-3.5 as well as the US devices Aminco and IBM were used. A decrease of the serum protein content from 9-13% appeared immediately after plasmaphereses with 1.3 l of plasma withdrawal per week and an average substitution of 40% of the protein loss by using a 5% solution of albumin. A continual control of this parameter is necessary.

Serum viscosity's increase in diabetes has been linked to the presence of microvascular sequelae and to changes in serum protein composition. The major change is a decline in albumin and an increase in the levels of acute-phase proteins. In this study, albumin and five acute phase proteins--alpha-1 acid glycoprotein, alpha-1 antitrypsin, haptoglobin, ceruloplasmin, and C-reactive protein--were measured. Levels in adult diabetes (principally type II) were compared with those in both subjects with glucose intolerance and control subjects (healthy subjects and nondiabetic ambulatory patients). Haptoglobin, alpha-1 acid glycoprotein, and C-reactive protein increased markedly in both diabetes and glucose intolerance; ceruloplasmin and alpha-1 antitrypsin increased more marginally. Serum albumin level decreased more strikingly as hyperglycemia advanced. Acute-phase proteins also increased in advanced glucose intolerance as in established diabetes. The acute-phase protein elevation did not differ with degree of control or duration of diabetes. When diabetics were divided into those with and without clinically detectable evidence of microvascular sequelae, elevation of haptoglobin, C-reactive protein and alpha-1 acid glycoprotein, and depression of albumin were found to progress with number of sequelae. The levels of these proteins, particularly haptoglobin, were also highly correlated with serum viscosity expressed as viscosity number. Mild serum albumin depression and a more striking acute-phase protein elevation are greater in diabetes with microangiopathy, develop in glucose intolerance, and contribute substantially to elevated plasma viscosity in diabetes.

A radioimmunoassay for glycated serum protein (GSP) was developed using monoclonal antibody to glucitollysine and polystyrene beads coated with Coomassie-Brilliant-Blue (CBB) as adsorbent for serum protein. The monoclonal antibody was raised by immunizing BALB/c mice with reduced glycated LDL and fusing their spleen cells with mouse myeloma cells. CBB-coated polystyrene beads were introduced to absorb a constant amount of serum protein. The protein adsorbed on the CBB-coated beads was reduced by NaHB4, and after treatment with radiolabeled antibody, the radioactivity of each bead was counted with an automatic gamma-counter. The standard glycated protein used was reduced glycated human serum albumin, in which 8 of 59 lysine residues were glycated. The intra- and interassay coefficients of variation of GSP were 4.8-6.5% and 1.6-6.0%, respectively. The GSP level of diabetic patients was significantly higher than that of normal controls (1.97 +/- 1.23 vs. 0.47 +/- 0.21 nmol/mg-protein; mean +/- SD, p less than 0.001). The GSP levels of patients with insulin-dependent and non-insulin-dependent diabetes mellitus were 3.03 +/- 1.05 and 1.51 +/- 1.00 nmol/mg-protein, respectively. A good correlation was found between the levels of GSP and hemoglobin A1c (HbA1c) (r = 0.85, p less than 0.001). In patients admitted to the hospital for diabetes education and glycemic control, the GSP level decreased 43 +/- 12% with the decrease in the fasting plasma glucose level (39 +/- 13%) and the mean daily plasma glucose level (MPG, 47 +/- 15%) in a four week period after admission, whereas the HbA1c level decreased only 13 +/- 6% during this period.(ABSTRACT TRUNCATED AT 250 WORDS)

This study was carried out on 55 diabetic patients, 20 of whom had diabetic nephropathy, and 10 controls. Glycosylated haemoglobin, glycosylated serum protein, glucoprotein, serum protein electrophoresis, blood urea, serum creatinine and beta 2-microglobulin were measured. A significant increase of glucoprotein was observed in patients with diabetic nephropathy. No correlation was found between glycosylated serum protein and glycosylated haemoglobin and duration of diabetes. Glycosylated serum protein showed a positive correlation with beta 2-microglobulin, indicating a link between renal involvement and the rise in glycosylated serum protein. Whether there is a pathogenic relation between glycosylated serum protein and the development of nephropathy awaits further evidence.
