We carefully selected 30 men with primary gout, rendered asymptomatic by therapy, to examine the frequency and type of hyperlipidemia and hyperlipoproteinemia, with the objective of determining whether serum uric acid, alcohol intake, liver function, kidney function, and (or) drugs were participating in the secondary lipid disorder. Sixty-one age- and sex-matched men were used as controls. About 73% of the gout patients had hypertriglyceridemia, 1.6-fold the frequency found in the control group. Types IV and IIb lipoprotein electrophoretic patterns were most prevalent in the gout group. Neither alcohol intake nor hyperuricemia, per se, seems to be the cause of the lipid and lipoprotein disorder and cannot be related to liver or kidney dysfunctions. Obesity was the major underlying factor associated with the lipidemia. The study suggests that diet and, possibly, defective clearance of triglycerides may be etiologic factors associated with the abnormal serum triacylglycerol (triglyceride) and lipoprotein concentrations in these individuals.

To evaluate the role of insulin in familial hypertriglyceridemia, 34 relatives of the pedigrees of 3 index cases of endogenous hypertriglyceridemia and hepatic steatosis as well as 9 spouses were examined for plasma lipids and responses of blood glucose and plasma insulin during oral glucose tolerance tests. The combined disorders of hypertriglyceridemia and hyperinsulinemia plus glucose intolerance--insulin resistance--were most commonly found among the relatives, which were often accompanied by an impaired liver function. Some relatives showed hyperinsulinemia without hypertriglyceridemia. Obesity was frequent, but its incidence was similar to the controls. Thus, the observed form of familial hypertriglyceridemia was apparently coupled with insulin resistance; and hyperinsulinemia, or insulin resistance by itself, might be a basic genetical trait in this form of lipid disorder.

1. Childhood obesity has been increasing for the last ten years in Tateyama City. Obesity in boys between the ages of 11 to 13 years was especially prominent. 2. Childhood obesity hardly improved especially in middle and morbid obesity. Eighty-five percent of light obesity in children lead to adult obesity. 3. Complications such as hypertension, serum lipid disorder and fatty liver were also observed in childhood obesity. Considering that Tateyama City is a typical Japanese country city, the above results could be representative of Japanese childhood obesity. Recent increases in childhood obesity might be due to the westernized dietary habit.

Obesity as a common disorder of lipid metabolism might be caused by defective hypothalamic control as demonstrated by ventromedial lesions or the effect of cholecystokinin application. The hypothalamic proopiomelanocorticotropin is the precursor of hormonal fragments affecting fat mobilisation, the endocrine pancreas and gastrointestinal functions.

Type V hyperlipoproteinemia is characterized by elevations of chylomicron (CM) and very low density lipoprotein (VLDL) triglycerides. The development of this lipid disorder involves a multitude of metabolic derangements including deficient clearance of triglycerides and/or their increased output aggravated by obesity, diabetes, alcohol intake, or use of some hormones. Some studies have suggested that the apolipoprotein E4 phenotype is involved in this dyslipoproteinemia but this concept is still a matter of controversy. Therefore, we determined the apoE phenotype in 21 patients with severe hypertriglyceridemia classified as type V. Their apoE4 gene frequency was 0.595 which is 2.6-fold higher (P less than 0.001) than that in the Finnish population. Correspondingly, their apoE3 gene frequency was lower than that in the normal population. No differences were noted in plasma lipoproteins of the apoE4 phenotypes and the other type V subjects. The apolipoprotein C-II and C-III distribution was similar to that in normolipidemic subjects. The results suggest that apoE4 may be involved in the development of type V hyperlipoproteinemia.

The first objective is to correct any existing coronary risk factors but this must be achieved with discrimination. Smoking should be strictly forbidden, hypertension reduced and a more active life style encouraged. However, a more nuanced approach should be adopted towards dietetic problems, obesity and disorders of lipid metabolism. It is also very important to teach the patient to use glyceryl trinitrate correctly in the double objective of relieving pain as quickly as possible and of preventing pain by using it in certain critical situations. Clinical practice shows that patients often use glyceryl trinitrate too sparingly. When these general measures have been settled, treatment must be adapted to each particular situation. The patient's age, the frequency of attacks, trigger factors, the repercussions of the disease on the patient's life all have to be considered before deciding on the individual's treatment. In younger patients, a controlled exercise ECG is essential for selecting patients for surgery. The drugs of choice for stable angina are the betablockers which have been shown to be effective and well tolerated. When this group of drugs cannot be used or is ineffective, other major anti-anginal drugs may be chosen according to the individual terrain and their known secondary effects.

The effects of treatment on plasma total triglyceride, total cholesterol, and plasma postheparin lipase activities have not been evaluated in non-insulin-dependent diabetic (NIDD) subjects without a coexisting familial lipid disorder. In 49 untreated NIDD subjects, there was a linear relationship between glycosylated hemoglobin (GHb) and triglyceride (r = 0.35, P less than 0.02). This correlation was improved after adjusting for the effects of obesity by a partial correlation analysis. After therapy, there was a significant relationship between the change in GHb and the change in triglyceride. To determine whether changes in lipid removal from plasma may contribute to the decrease in plasma lipid concentrations during treatment, the plasma postheparin lipoprotein lipase and hepatic lipase activities were evaluated in a subgroup (N = 8) of these NIDD subjects before and after 1 and 3 mo of therapy. Plasma postheparin hepatic lipase activity in the NIDD subjects was not different from that observed in six normal control subjects and did not change during therapy. In contrast, plasma postheparin lipoprotein lipase activity was lower in the untreated NIDD subjects than in the control subjects. Analysis of the two phases (early and late) of the postheparin lipoprotein lipase activity in plasma showed that the abnormal early phase in untreated NIDD corrected to normal values in less than a month, but the late phase was not corrected until the 3-mo measurement. These findings suggest that some NIDD subjects have a defect in heparin releasable lipoprotein lipase activity, which is reversed with improved glycemic control.(ABSTRACT TRUNCATED AT 250 WORDS)

The Zucker rat (ten weeks old) is characterized by a large increase in plasma triglyceride, which is accompanied by a smaller augmentation of phospholipids and tri-unsaturated cholesteryl ester levels. On the other hand, lipid increases in hyperphagic animals are characterized by less hypertriglyceridemia but significant hypercholesterolemia involving several lipoprotein fractions. Variation in time and start of these changes were observed, using a thin layer chromatography method. In goldthioglucose (GTG) mice variations in plasma lipids of controls were irregular, consequently the influence of obesity was expressed as the ratio obese/control as functions of time. The levels of total lipids, cholesteryl ester, triglyceride, lecithin and lysolecithin had a linear progression with time in contrast to sphingomyelin, saturated and tri-unsaturated cholesteryl ester. Two phases can be distinguished in the variation of lipids in GTG mice: the first corresponding to onset, up to the seventh week, and the second corresponding to definite obesity. In Zucker rats lipid levels of lean rats decrease with time while they increased in obese rats. Triglyceride increase was predominant at each period of the study. Changes in total lipids, triglyceride, free fatty acids, cholesteryl ester, lecithin and lysolecithin were also linear. These results make it evident that the lipid disorder as described in the adult begins very early. Because the variations in lipid levels are more regular, the Zucker rat is preferable to GTG mice as a model of obesity.

The influence of the efficacy of triglyceride and cholesterol correction on cardiovascular complications and mortality was analysed in a follow-up study with 260 patients with primary HLP (triglycerides before entry greater than 2.9 mmol/l and/or cholesterol greater than 7.8 mmol/l). The follow-up time was 67.4 +/- 27 months. It was hypothesised that reduction of elevated levels of triglycerides and/or cholesterol influenced favourably the incidence of angina pectoris, MI, stroke and total mortality. For ethical reasons, it was not possible to carry out the investigations with a control group. Therefore, we performed an internal comparison of 3 categories of lipid correction achieved during the trial (effective, moderate, insufficient). A substantial improvement of the lipid disorder was obtained by individualizing the therapy. Triglycerides and cholesterol decreased on average by 50% and 20%, respectively. The incidence of MI was 10 times higher than in the general population. With respect to the type of HLP, hypertriglyceridemia revealed a significantly higher incidence of MI compared with hypercholesterolemia and mixed HLP. The therapy variant was only of importance with respect to gallstone diseases accumulating in the CPIB-treated subgroups. We found a majority of cases with newly manifested angina pectoris and stroke in the group with moderate correction of both triglycerides and cholesterol. Patients with effective triglyceride and cholesterol correction suffered less frequently from MI than those with insufficient correction. This was also the case with secondary prevention in cases with MI prior to entry. There was no significant difference in the distribution of lipid categories at entry between those with and without recurrent infarction. In the group without reinfarction, however, the percentage with insufficient control diminished significantly. Associated risk factors such as hypertension, diabetes, smoking and obesity were of minor or no significance. In subjects with effective triglyceride correction, the total mortality was 0.97/1000 treatment months vs. 3.63 in insufficiently treated patients. The figures for MI mortality were 0.36 and 1.91, respectively.

The authors studied the X-ray grams of soft tissues of the lower limbs of 120 patients with diabetes mellitus--54 males and 66 females and 42 control subjects (18 males and 24 females). The average age of the latter was 56.3 and of the patient--52. According to their characteristic the calcifications were localized in intima (spotted) and in media (linear). Besides localization, the extend (whole artery or partial) and degree (light, pronounced) of calcifications were determined. Mediocalcinosis in the arteries of lower limbs of diabetics was established to be almost four times more frequent than that among the controls, the arteries of the thighs, legs and foot being equally affected. In 1/3 of the cases the whole vascular system of the lower limbs was involved, being more frequent in males, as compared with females, with a statistical significance, and correlated significantly with age and duration of the disease. Mediocalcinosis was more frequent with statistical significance, in patients, treated with sulfonylurea preparations. Attempt was made to explain that fact, besides by the older age of those patients with some humoral and hormonal characteristics of diabetes of the elderly, sensitive to SU preparations namely: the presence of hyperlipoproteinemia, hypersomatotropism and relative hyperinsulinism, favouring the proliferation of the cells of media and deposition of calcium salts in it. No statistically significant correlation was found between the incidence of mediocalcinosis on the one hand and the type of diabetes, severity of the disease, occupation, past infections, the presence of hypertension, obesity, retinopathy and disorders of lipid metabolism--on the other.
