[HLA antigens in type II diabetics].

The study examined the relationship between class I HLA antigens and type II diabetes with regard to insulin secretion and hyperlipoproteinemia. Out of 28 HLA antigens of A, B and C loci, 46 type II diabetics had statistically more significant HLA Cw1 - 15.9% as compared with 6.3% of the control group, the relative risk being 2.81. These patients were younger than the other diabetics but showed no difference in insulin secretion or hyperlipoproteinemia. Diabetics with HLA Cw4, just as patients after myocardial infarction with concomitant hyperlipoproteinemia, were also found frequently to have hyperlipoproteinemia (89 percentage cases as compared to 63% of the other diabetics). The findings may be indicative of potential genetic heterogeneity of type II diabetes. The paper stresses the necessity of establishing suitable genetic characters for early diagnosis of diabetes and its development.

[Long-term administration of a low-protein diet with keto-analogs of essential amino acids and the metabolic status of patients with chronic kidney failure].

To 12 patients with chronic renal failure (CHRI) for 12-22 months a diet containing 20 g high quality protein supplemented by keto analogues of essential amino acids (KA)--4.8 g/day--was administered. During the investigation period no significant change of the albumin, prealbumin or transferrin level was recorded, nor of Whitehead's quotient, immunoglobulin levels and haemoglobin concentration, serum iron and its binding capacity. However, there was decline of the C3 complement component (p less than 0.01). The investigated parameters of carbohydrate metabolism (fasting blood sugar, immunoreactive insulin, oral glucose tolerance test) did not change, similarly as total cholesterol and triglyceride levels. The originally reduced HDL-cholesterol level increased (p less than 0.05). The achieved results suggest that the long-term administration of a diet with 20 g protein supplemented by the minimal necessary dose of KA does not produce undesirable changes of the investigated metabolic parameters.

[Metabolic and ultrastructural changes in the myocardium during heart arrest in patients undergoing surgery for ischemic heart disease].

The authors give an account of metabolic changes in the ultrastructure of the myocardium which develop during cardioplegic arrest of the heart muscle by cold during aortocoronary reconstruction operations. Using the technique of arteriovenous differences before myocardial ischemia and after its termination, the assessed differences in arterial blood and blood from the sinus coronarius as regards the blood sugar level, lactate, pyruvate, potassium, phosphorus, unsaturated fatty acids and triglycerides. The results revealed a marked disorder of the carbohydrate and ion metabolism and severe impairment of the ultrastructure of the heart muscle during cardiac arrest.

[Levels of HDL cholesterol and the HDL2 and HDL3 subfractions in newly detected type 2 diabetes].

In a group of 40 newly detected middle-aged diabetics the authors recorded reduced HDL cholesterol levels and elevated triglyceride and total cholesterol levels. After compensation of diabetes the cholesterol and triglyceride levels became normal, the HDL cholesterol levels remained, however, low. By comparison of the sub-fractions of HDL cholesterol in diabetics with the control group it was revealed that in the diabetic group the HDL2 cholesterol levels were significantly reduced. The HDL3 cholesterol was not significantly altered. The reduction of the total HDL cholesterol was due mainly to low HDL2 cholesterol, while the HDL3 cholesterol level was normal. Low HDL cholesterol levels and those of the HDL2 sub-fraction in newly detected diabetics indicate the increased risk of development of atherosclerosis.

Serum lipids and apolipoproteins in families of postinfarction men.

The study of relatives of postinfarction patients was designed to assess the familial associations of lipids (total cholesterol, triglycerides, high density lipoprotein-cholesterol), and of apolipoproteins A and B. Examination of 493 individuals from 106 families showed only some familial associations of serum lipids between mothers and offspring and among siblings, but similar associations in apolipoproteins among all groups of direct relatives (i.e. between mothers and offspring, among siblings and between fathers and offspring). Associations among direct relatives, and their absence between spouses, suggest the genetic influence on lipoproteins. Apolipoproteins appear to be a more suitable means of detecting such associations than serum lipid levels.

[Behavior of HDL cholesterol and the apoproteins A1 A2 and B in the central circulation in patients with coronary disease and genetically determined hyperlipoproteinemias].

Seven lipid parameters, including apoproteins A1, A2 and B were determined in blood from different parts of the cardiovascular system in two groups of patients one with and the other without coronary heart disease. In addition, HDL cholesterol levels were compared in patients with coronary heart disease and primary monogenic combined hyperlipoproteinaemia. None of the seven parameters showed significant differences in samples from the pulmonary artery (mixed venous blood) and the hepatic vein of the control and patient groups. The expected significant concentration gradient between the two vascular regions was confirmed in the groups with and without coronary heart disease. HDL components showed a contrary behaviour: the hepatic vein and pulmonary artery exhibited significantly lower values of HDL cholesterol in patients with coronary heart disease than in the controls, but this was not true for HDL apoproteins A1 and A2. Patients with coronary heart disease and primary hyperlipoproteinaemia showed a significant concentration gradient between the two vascular regions for total and HDL cholesterol. These observations reveal the importance of genetic disturbances of lipid metabolism, particularly the implication of various lipid fractions in the pathogenesis of atherosclerosis.

Serum linoleic acid and cardiovascular death in postinfarction middle-aged men.

Linoleic acid in serum total lipids was the first variable in the stepwise regression analysis of metabolic, nutritional and cardiovascular factors in a secondary preventive study of postinfarction middle-aged men. It was followed in the regression analysis where the dependent variable was cardiovascular death by previous myocardial infarction, heart volume index and hyperlipoproteinaemia. Linoleic acid was the only fatty acid entering the regression. Unlike other fatty acids, it exhibited by its low percentage an accumulation of deaths. The decreased percentage of linoleic acid was also evident in the comparison of fatty acid patterns of cardiovascular deaths to age- and triglyceride-matched men free from ischaemic heart disease. This study confirms prospective associations found in previously healthy men. Conclusions are drawn about the relevance of low serum linoleic acid to long term prognosis after MI.

Fractional cholesterol esterification rate and muscle cholesterol of healthy young men.

A group of fourteen healthy young male volunteers was examined to define more exactly the relations between lecithin cholesterol acyltransferase activity (LCAT), fractional cholesterol esterification rate (FER), total cholesterol (TC) and its free and esterified fractions (FC, CE) in skeletal muscles under physiological conditions. The mean values (+/- S.D.) of LCAT activity (95.4 +/- 16.3 mumol .1(-1) per hour), and FER (7.45 +/- 1.54% per hour) corresponded to published data on normolipidaemic healthy men of normal body weight. The mean value of TC in muscles was 332 +/- 83 micrograms per 100 mg of non-collagen protein, of which 14 +/- 7.4 per cent was formed by cholesterol esters. There was positive correlation between TC in muscles and age. Significant positive correlations between FER and the content of esterified cholesterol in muscles, and between FER and the proportion of esterified to total muscle cholesterol were found. These results suggest a close interrelation of cholesterol ester metabolism in the plasma and in slow pool tissues.
