The importance of the gout is growing in the GDR as its frequency has been increasing since the sixties. The gout is a disease of metabolism with the following accompanying phenomena: renal lesion in gout, hypertension, cardiac diseases and peripheral arterial diseases. Besides, there are proved relations between hyperuricemia and obesity, hyperlipoproteinemia, diabetes mellitus as well as steatosis hepatis. In describing the nature of the gout the peculiarities of age are stressed. The treatment of the gout depends on the clinical state.

Basal values of lecithin:cholesterol acyltransferase (LCAT) were estimated in healthy subjects, in patients with the so-called risk ischemic heart diseases (IHD)--obesity, diabetes, hypertension, and hyperlipoproteinemia II--and in patients with a IHD-infarction of the myocardium. A precise method employing a 14C-4-cholesterol-labeled common normolipidemic substrate was used. A highly significant difference in the average values of LCAT activity between healthy men and women was found. LCAT in men with 'risk' diseases decreased, while in women it remained at the level of the reference group. To assess the dependence between LCAT-dependent indicators and IHD, criteria for evaluating the deviations from reference values were proposed. The number of deviations from the reference group increased in the sequence: obesity, hypertension, diabetes, hyperlipoproteinemia, and the infarction of the myocardium.

In a series of 175 adult renal transplant patients 59% of patients had hyperlipidemia. Hyperlipidemia in these patients was characterized by both hypercholesterolemia and hypertriglyceridemia and on lipoprotein electrophoresis was demonstrated to be a mixture of types IIa, IIb and IV hyperlipoproteinemia. Serum cholesterol and triglyceride levels could both be related to the dosage of prednisone these patients received. Serum triglyceride levels could further be correlated with obesity and negatively with the duration of graft function. The latter relationship was felt to reflect the lower dose of prednisone that was administered the longer the duration of graft function. Hypertriglyceridemia was more prevalent in the 47 transplant patients who received kidneys from cadaver donors than in the 128 patients who received kidneys from related-donors. The cadaver-donor renal transplant patients, however, were receiving a larger maintenance dose of corticosteroids and had had functioning transplants for a shorter period of time. In 17 patients followed for up to 20 wks immediately following transplantation both hypercholesterolemia and hypertriglyceridemia developed within 8 wks of transplantation and persisted for the remaining 12 wks. Both serum cholesterol and triglyceride levels in this early post-transplant phase could be related to the cumulative prednisone dosage.

With the world-wide increase of the number of ischemic heart diseases the significance of the so-called factors of risk which initiate an arteriosclerosis or can deteriorate it, respectively, has increased. In the Dresden study concerning the most important factors of risk we found the following frequencies: obesity 8.2%, hyperlipoproteinemia 7.4%, hyperuricemia 3.8%, diabetes mellitus 2.0%, hypertension 17.2% and smoking 30.3%. From the investigations results the great significance of the combination of factors of risk which has a potentiating effect. The hyperlipoproteinemias of type III-V most frequently show a disturbed carbohydrate tolerance and hypertension. In them also the most frequent severe changes of the ECG appear. Myocardial infarctions concerned above all type II-IV. Apparantly concerning the vascular system patients with the combination hyperlipoproteinemia and carbohydrate metabolism are particularly endangered. The "metabolic syndrome" (obesity, diabetes mellitus, hyperlipoproteinemia, hyperuricemia, steatosis hepatis) with the increase of the viscosity of blood and plasma as well as disturbances of coagulation together with other factors of risk further the development of arteriosclerosis or has a directing influence on it. Nevertheless, the concept of the significance of the factors of risk is not able to predict the risk in every case. With the help of the apoproteins the metabolic risk is to be more exactly estimated by the determination of the lipid values in the individual classes of lipids or by classification.

The epidemiological patterns for pancreatic and biliary cancers reveal more differences than similarities. Pancreatic carcinoma is common in western countries, although 2 Polynesian groups (New Zealand Maoris and native Hawaiians) have the highest rates internationally. In the United States the disease is rising in frequency, predominating in males and in blacks. The rates are elevated in urban areas, but geographic analysis uncovered no clustering of contiguous counties except in southern Louisiana. The origin of pancreatic cancer is obsure, but a twofold increased risk has been documented for cigarette smokers and diabetic patients. Alcohol, occupational agents, and dietary fat have been suspected, but not proven to be risk factors. Except for the rare hereditary form of pancreatitis, there are few clues to genetic predisposition. In contrast, the reported incidence of biliary tract cancer is highest in Latin American populations and American Indians. The tumor predominates in females around the world, except for Chinese and Japanese who show a male excess. In the United States the rates are higher in whites than blacks, and clusters of high-risk counties have been found in the north central region, the southwest, and Appalachia. The distribution of biliary tumors parallels that of cholesterol gallstones, the major risk factor for biliary cancer. Insights into biliary carcinogenesis depend upon clarification of lithogenic influences, such as pregnancy, obesity, and hyperlipoproteinemia, exogenous estrogens, familial tendencies, and ethnic-geographic factors that may reflect dietary habits. Noncalculous risk factors for biliary cancer include ulcerative colitis, clonorchiasis, Gardner's syndrome, and probably certain industrial exposures. Within the biliary tract, tumors of the gallbladder and bile duct show epidemiological distinctions. In contrast to gallbladder cancer, bile duct neoplasms predominate in males; they are less often associated with stones and more often with other risk factors. In some respects, bile duct and pancreatic tumors are alike. The male predominance of both tumors, an association between cholecystectomy and pancreatic cancer, and other considerations have prompted the notion that the same biliary carcinogens may affect the bile duct, ampulla of Vater, or, by reflux, the pancreatic duct. Various epidemiological and interdisciplinary approaches are needed to further clarify the origins of biliary tract and pancreatic cancers, but nutritional studies hold special promise in laying the groundwork for prevention of these tumors.

In a controlled study on 121 patients with peripheral vascular disease (PVD) (75 patients with primary hyperlipoproteinemia, 15 diabetics, 31 patients without metabolic disease) the relationship between risk factors (hyperlipoproteinemia, obesity, hypertension, abnormal glucose tolerance, smoking) and the degree and localisation of sclerotic lesions was investigated by angiography. The degree was directly related in all patients to the number of risk factors, in Type IIa to cholesterol levels, in diabetics and Type IV with abnormal glucose tolerance to age. The latter patients were 5-10 years older than patients with Type IIa and showed 2 or more additional risk factors. The sclerotic lesions affected in Type IIa, less in Type IIb, predominately the pelvic vessels. Diabetics and Type IV patients showed a distal arterial involvement. The difference was significant. The degree of sclerotic lesions in arteries of the pelvis and the distal lower limb was positively correlated with the cholesterol-triglyceride ratio. Smoking aggravated the pelvic lesions in Type IV. Hypertension lead to more pronounced lesions of the distal lower limb in Type II. S-shaped tortuosities of the big vessels were shown to be typical, independent of localisation or degree.

Concentrations of immunoreactive insulin activity (IRI) and proinsulin activity (IRP), blood glucose, free fatty acids (FFA), glycerol, cholesterol, triglycerides were analyzed in 140 subjects suspect of protodiabetes and 50 healthy persons before, during and after a glucose infusion test (GIT). The protodiabetic subjects were classified into normweight, overweight, obese, hyperlipemic groups with diet or with Regadrin therapy and each of them subdivided into such with normal and such with pathological carbohydrate tolerance. Norm- and overweight subjects with asymptomatic diabetes were characterized by a significant reduction of insulin secretion during both phases. Obese patients with or without hyperlipoproteinemia demonstrated an increased IRI reaction during the late phase of secretion. Carbohydrate intolerance was associated with an enhancement of basal triglyceride levels and a reduced depression of glycerol and FFA during the GIT. There were no differences in fasting or reactive IRP concentrations between healthy and protodiabetic subjects with normal carbohydrate tolerance. In asymptomatic diabetes the IRP levels were increased during the late secretion phase, but the percentage of IRP in total IRI was normal or--in existing high response--significantly reduced in comparison to norm response. The results do not support an enhanced IRP secretion as the cause of carbohydrate intolerance.

Asymptomatic hyperuricemia should be treated only if the plasma uric acid levels are around 10 mg/100 ml or more on several determinations. In addition, patients on a purine-free diet who excrete more than 600 mg uric acid per 24 h should be treated. In both cases, treatment is intended to be prophylactic against gouty nephropathy. At present there is no evidence that primary hyperuricemia alone is a risk factor for early atherosclerosis and especially coronary artery disease. However, more attention should be paid to the accompanying risk factors such as obesity, hyperlipoproteinemia, diabetes mellitus and hypertension.

This study has been designed to evaluate whether duration and severity of obesity can influence left ventricular function response to exercise in obese subjects without other known cardiovascular risk factors such as hypertension, diabetes or hyperlipoproteinemia. A total of 29 obese subjects were included and they were divided, according to their body mass index and to Garrow's criteria as follows: Overweight or mildly obese subjects: body mass index from 25 to 30 kg/m2; moderately obese subjects: body mass index > 30 and < 40 kg/m2. Both obese groups were further subdivided according to their duration of obesity evaluated by accurate anamnesis in subgroup A (duration of obesity less than 120 months) and subgroup B (duration of obesity more than 120 months). Left ventricular ejection fraction was detected by blood pool gated radionuclide angiocardiography both at rest and after symptom-limited bicycle ergometer procedure. At peak exercise left ventricular ejection fraction increased significantly (p < 0.05) only in overweight subjects. Exercise produced an increase of left ventricular ejection fraction in 14 overweight and in 5 moderately obese subjects and a decrease in 2 moderately obese subjects. At peak exercise mean heart rate and mean blood pressure increased significantly (p < 0.001) in both groups. When obese subjects were subgrouped according to duration of obesity, left ventricular ejection fraction increased significantly (p < 0.05) only in overweight subjects with duration of obesity less than 120 months. Duration of obesity correlated inversely with percent change in left ventricular ejection fraction (EF) at peak exercise (delta EF) (r = -0.59; p < 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)

A study of the programmed nurse clinic in a health center was carried out to evaluate its different health care activities, the time consumed in them, the type of patients cared for, and the mechanism of organization of the clinic. A remarkable finding was a high number of daily appointments (11.8 persons), with an excellent rate of compliance with the appointment (89.3%). It was found that most of the diseases cared for in the nurse clinic were those most commonly managed with a protocol design in primary care: hypertension (34.1%), diabetes (6.9%), hyperlipoproteinemia (9%) and obesity (12.8%). Other parameters were evaluated, such as mean time per visit, which was predominantly between five and ten minutes, or activities during the visits, with a clear predominance of the clinical protocols. There was a remarkably high efficiency of the nursing staff, with a low rate of referral to the medical clinic (6.9%). We conclude that nurse clinics play an important role in the health centers, as the only possible mechanism to guarantee the correct fulfillment of the different programs. This requires a definite constant physical space for a given minimal period of time of about 2 hours per day.
