221 patients with arterial hypertension were investigated as outpatients. 198 patients were found to have primary and 23 patients to have secondary hypertension. The results of urinary analysis were pathological in 25% of patients and renal function tests were abnormal in 20% of cases. Significant bacteriuria was recorded in 19% of urinary cultures. Intravenous pyelography showed true pathological findings in 12% of cases, false positive findings in 7% and false negative findings in 5%. Isotopic nephrograms showed true positive findings in 52%, false negative in 3% and 45% showed normal results. In 53% of patients angiography of the kidneys showed normal results, whilst this investigation proved pathological in 44% of cases and gave false negative results in 3% of patients. An additional search for coronary heart disease risk factors revealed that 73% of these hypertensive patients were overweight, 47% had hyperlipidaemia, 33% suffered from diabetes mellitus and nicotine abuse was present in 21% of cases. A relevant yet inexpensive screening programme for the investigation of hypertension is formulated on the basis of the results of this investigation.

Starting from previous observations emphasizing an increased pseudocholinesterase (PCE) activity in obese and hyperlipemic subjects, the behaviour of this enzyme and of ceruloplasmin was studied in connection with changes of serum lipids and lipoproteins in various types of hyperlipoproteinemia. When compared to values detected in 67 middle-aged normal weight normolipemic subjects, PCE activity was found to be significantly greater (smaller than 0.001) in the 49 overweight subjects without obvious hyperlipemia but presenting a moderate increase of the prebeta electrophoretic fraction. PCE activity was much higher in lean or overweight subjects with endogenous hypertriglyceridemia (68 patients with type IV and 86 patients with mixed hyperlipemia). The slight increase of mean values of PCE activity in the 53 subjects with type II-a was due mainly to overweight subjects, while this enzyme's activity was not significantly changed in lean subjects with pure hypercholesterolemia. PCE activity was positively correlated with serum triglyceride (r equals 0.540; p smaller than 0.001) and the prebeta electrophoretic fraction (r equals 610; p smaller than 0.001). The correlation with beta-lipoproteins was not significant. Ceruloplasmin levels were not significantly changed. It is suggested that elevation of PCE activity could be connected to mechanisms leading to an increased secretion rate of lipoproteins.

One hundred and ten adult out-patients entered a prospective study of the effect of dietary control of hyperlipidaemia. Seventy-nine were male and 31 female. Eighty-four patients had primary type II and 26 had primary type IV hyperlipidaemia. Cases of secondary hyperlipidaemia were excluded. Patients with type II hyperlipidaemia were treated with a diet low in saturated fat and cholesterol, with substitution of polyunsaturated fats. Additional carbohydrate and alcohol restriction was applied to patients with type IV hyperlipidaemia. Calorie restriction was prescribed for overweight patients. In type II patients, mean serum cholesterol fell from 322 to 286 mg per 100 ml, and weight from 159 to 152 lb over the first six months of treatment. In type IV patients cholesterol fell from 328 to 281 mg per 100 ml, triglycerides from 389 to 241 mg per 100 ml and weight from 166 to 156 lb over the same period. All reductions were statistically significant at the 1 per cent level. No statistical correlation was observed between reduction of weight and reduction in lipid levels. Over a three-year follow-up period no tendancy for lipid levels or weight to 'rebound' was noted. It is concluded that diet can produce a significant reduction in plasma lipid levels over six months in some hyperlipidaemic patients. Further follow-up is continuing to determine whether this effect can be maintained over the longterm.

Benign symmetric lipomatosis (BSL) leads to characteristic multiple lipomas of the neck and submandibular region. BSL is easily diagnosed by its typical feature, "Madelung's neck". However, the early stages are often missed or lead to futile diagnostic endeavours. A report is presented on 7 men with BSL aged 36--65 years who were investigated with regard to alcohol consumption, clinical findings and liver histology. This is the first time that liver histology has been systematically worked up in patients with BSL. All admitted long standing ethanol intake (x = 111 ml/day) prior to the development of BSL. The growth of the lipomas was irregular and occurred over a period of months. There was no correlation with overweight or hyperlipidemia. However, liver biopsy revealed features consistent with alcoholic liver disease in all subjects. It is suggested that BSL is a symptom of alcoholic liver disease mainly affecting middle-aged men.

Red cell deformability, which allows cells of 7 mu diameter to flow through capillaries not larger than 3 mu, can be approached by the measure of blood filterability on nuclepore 5 mu filters. Filterability is reduced in arterial diseases. We have, in 72 patients, correlated red cell filterability, with the number of cardiovascular risk factors present high blood pressure, overweight, diabetes, hyperuricemia, hyperlipemia smoking). There is a statistical difference between groups with risk factors present as a whole and with O risk factor (p less than 0.01). The difference is highly significant between O and 4 risk factors (p less than 0.0005). Filterability decrease is also directly correlated with the number of cigarettes smoked per day (less than 0.05) and decrease is enhanced by smoking two cigarettes.

Groups of patients such as the elderly, the diabetic and women have been studied to evaluate the effectiveness of coronary revascularization. In this report 77 patients under age 40 years undergoing coronary revascularization were studied. There was a high prevalence rate of predisposing factors. Sixty-eight percent reported a family history of heart disease and 27 percent a history of diabetes; 57 percent were hypertensive, 43 percent were overweight, 91 percent smoked, 5 percent were diabetic and 16 percent had abnormal glucose tolerance curves. Sixty-four percent had hypercholesterolemia (cholesterol 250 mg/100 ml) and 56 percent hyperlipidemia. Forty-four percent had had a previous myocardial infarction; 95 percent had angina pectoris, 12 percent preinfarction angina and 9 percent congestive cardiac failure. There were no operative deaths. The incidence rate of perioperative myocardial infarction (new Q waves in the electrocardiogram) was 4 percent. The mean length of of follow-up was 26 months (range 6 months to 5 years). The late mortality rate was 4 percent. Eight percent had a late myocardial infarction. Overall graft patency was 85 percent. Sixty-seven percent of patients were free of angina, and 17 percent were in improved condition. Seventy-one percent returned to work, while 29 percent remained unemployed. This study shows that in young patients, coronary revascularization is associated with low mortality and morbidity rates and that, despite the wide prevalence of predisposing factors, the prognosis and graft patency rate of these patients are similar to those of other groups.

Serum lipids in 58 renal transplant recipients were related to duration of follow-up, relative body weight, steroid medication, proteinuria and graft performance. Hyperlipidemia was observed between the 4th month and the end of the first year after transplantation in 83% of the patients. Thereafter, the frequency of hyperlipidaemia appeared to decrease: at 4 to 7 years only 61% of the subjects continued to exhibit abnormal high serum lipids. Three mechanisms leading to hyperlipidaemia were identified: 1) overweight, 2) steroid mediation, 3) proteinuria. A forth apparent mechanism was impaired transplant function.

A brief survey of the literature on the side effects of oral contraceptives is given. Of the many influences on laboratory results those related to (reversible) cholestasis or to a change in protein synthesis are the most important ones. A decrease of the tolerance for glucose is sometimes observed. Few of the clinical side effects attributed to oral contraceptives can be directly correlated with the pharmaceutical action of these drugs. Many so-called side effects of the pill are due to other factors such as altered psychosociological or sexual behavior, etc. However, among users of oral contraceptives there is a significant decrease in the number of benign tumors, particularly of the breast, the uterus and the ovaries. It is still an open question if this also signifies protection against cancer. Anemias due to iron deficiency are less frequent among users of the pill. According to recent studies arterial hypertension and cholecystopathies are probably directly related to oral contraceptives, but a causal relation has not been proven for migraine, headaches, depression etc. An elevated risk for vascular complications seems to be well established: there is a 4-6-fold increase of the estimated risk for venous thrombo-embolism and a 4-9-fold increase for cerebrovascular accidents among users of oral contraceptives when compared with nonpregnant women of the same age not using the pill. Oral contraceptives act as a supplementary factor of risk which may cumulate with other similar factors, such as arterial hypertension, hyperlipidemia, overweight, smoking etc. Mortality due to oral contraceptives is very much 10-50 x) inferior to the one caused by delivery and the post partum state. Since the number of failures in prevention of pregnancies is less for oral contraceptives than for any other method of contraception, the overall risk of death under oral contraceptives in this age group of women is least.

Statistical analyses were performed in order to determine the effects of the control of the diabetes as well as the food intake on serum lipid levels of 73 diabetic outpatients. They had had elevated fasting blood glucose levels, mostly complicated by various grades of hyperlipidemia, before the initiation of treatment. Hyperlipidemia was found to be ameliorated in nearly half of those patients after the start of diabetic treatment. However, the elevation of serum triglyceride persisted in 30 per cent of controlled diabetics, and no differences were found in occurrence of hypertriglyceridemia between diet-treatment group, sulfonylurea group, biguanide group, combined group and insulin group. Estimation of diet intake revealed that the controlled hypertriglyceridemic patients consumed slightly (but significantly) greater amounts of sucrose, alcohol, and total calories than the controlled normotriglyceridemic patients. In addition to such inadequate diet consumptions, the tendency to be overweight and the subtle increment of fasting blood glucose levels were also shown to have contributed to hypertriglyceridemia. It is thus concluded that the lipid disorder in controlled diabetic outpatients is the result of multifactorial influences and that well-conducted diet therapy and stricter regulation of blood glucose are essential in the management of posttreatment hyperlipidemia.

Benign symmetric lipomatosis (BSL) leads to characteristic multiple lipomas of the neck and submandibullar region. Seven men with BSL, aged 36--65 years, were investigated with regard to alcohol consumption, clinical findings and liver histology. They admitted a long standing ethanol intake (x = 107 ml/day) prior to the development of BSL. The growth of the lipomas was irregular and occurred over a period of months. There was no correlation with overweight or hyperlipidemia. However, liver biopsy revealed features consistent with alcoholic liver disease in all subjects. It is concluded that BSL represents a symptom of alcoholic liver disease affecting middle aged men.
