Thyroid and obesity: survey of some function tests in a large obese population.

Tests of thyroid function in 493 obese patients were compared with thyroid function in 3076 non-obese patients. No differences in 131I uptake by the thyroid were observed at 6 h or 24 h; the frequency distribution was gaussian or normal in both populations; the frequencies of normal, high or low T3 and T4 values in the two populations were likewise comparable. Further, no correlation was found in the obese subjects between 131I uptake (6 h and 24 h), T3, T4 and overweight; on the other hand, there was a significant negative correlation between 131I uptake (6 h and 24 h) and age. It would appear that thyroid function is normal in obesity.

[Aspects of glycolipid metabolism in chronic renal insufficiency: interference of oral glucose administration during and after dialysis with changes induced by short dialyses with glucose free dialysate].

As part of some research into certain aspects of glycolipidic metabolism in chronic renal insufficiency, a study has been made of alterations in glycaemia, insulinaemia, free fatty acids and triglycerides during and following brief periods of dialysis by glucose-free bath in 26 subjects: within this group, 50 g of glucose were administered to 8 patients at the 2nd hour of dialysis and 100 g to another 8 at the end of therapy. The following findings were made during glucose-free dialysis: marked hypoglycaemia starting from the first hour until the end, marked increase in FFA and marked fall in TG upon the lipolytic action of heparin. In the post-dialysis period, immediate normalization in glycaemia, steady diminution in FFA and notable increase in TG as early as the 1st hour. Administration of glucose during dialysis prevents hypoglycaemia by altering FFA and TG behaviour in the post-dialysis period. Administration of glucose at the end leads to hyperglycaemia and hyperinsulinaemia with marked fall in FFA and TG. During dialysis, the phenomena observed depend on the action of heparin, acetate and the absence of glucose. This absence brings on hypoglycaemia with secondary glycogenolysis and-or neoglucogenesis during dialysis; in the post-dialysis period, hepatic neosynthesis of TG in the presence of normal glycaemic and insulinaemic values. Glucose per os determines hyperglycaemia and secondary hyperinsulinaemia with FFA esterification at the level of adipose tissue and a fall in serous TG.

[Food consumption in a community of the Parma district (Langhirano). Clinico-metabolic considerations].

Referring to the results of a "pilot" nutritional investigation carried out in a representative mixed sample of a small community of Parma district (Langhirano), the AA. underline the clinical and metabolic implications resulting from the not quite correct nutritional behaviour observed. In fact, in agreement with the national average data reported for italian population from ISTAT, caloric excess, particularly of dietary fat and proteins, was confirmed in this community too. Nevertheless, want of vitamins (D, B1, B2), and minerals (Ca) was paradoxically found. Considering in detail the results some immediate clinical and metabolic consequences come out: namely, want of Ca is prevailing in women and just in the critical age classes (20-40 and 50-59 years, that is in fertile and climacteric ages). When the recommended intake levels are higher. Ferthermore in male-populations, in the class aged 30-50 (that is more vulnerable as to atherosclerosis), was found the highest caloric intake besides in fat and particularly in cholesterol, as to the recommended safety levels. The A.A. conclude pointing out the importance and the necessity of a nutritional notions wide spreading, involving the various responsible public health and social politic organisation of the Country.

Epidemiological aspects and social importance of obesity. The situation in Italy compared with other developed countries.

Epidemiological aspects of obesity have been the object of few studies in Italy, and the results of these are reviewed and compared with those obtained in other developed countries. The prevalence of obesity has been investigated in pre-school and school-age children, in young conscripts and in workers at the Riuniti Hospital in Parma, and the results show that the problem of obesity in Italy is a serious one. More than 2000 obese subjects, attending the First Medical Clinic of Parma University, have been studied to establish how far overweight is responsible for pathological and disabling complications. Obesity was implicated as a major contributing factor in diabeties, atherosclerosis, hypertension, arthritis and many other disabling diseases. The social aspects of the problems of obesity are discussed, together with possible preventive and curative measures.

Observations on lipid metabolism in chronic renal failure, during conservative and haemodialysis therapy.

The main variables of glycolipid metabolism (blood non-esterified fatty acids, triglycerides, cholesterol, insulin, glucose) have been measured in basal conditions in uraemic patients on conservative treatment and on dialysis of different duration and bath glucose concentration (no glucose, 1 g/l, 2 g/l). Basal values for the patients on conservative dietary treatment are not different from normal. In dialysed patients, the blood non-esterified fatty acid and triglyceride concentrations are increased (p less than 0.001) while cholesterol glucose and insulin levels are unchanged. No significant difference is found between the various types of dialysis, having different duration and bath glucose concentration

Glycolipid modifications during peritoneal dialysis in patients with chronic renal failure.

Ten patients with progressive CRF were studied for the major indices of glycolipid metabolism during the first application of peritoneal dialysis. From the 2nd hour the concentration of dialysis fluid is 4.5g%, while the electrolyte content is unchanged. During treatment a constant increase of glycemia and insulinemia with a fall of plasma-free fatty acids and serum triglycerides was observed. The authors attribute such modifications to hyperglycemia and consequently to the high glucose of the dialysis bath.

[Aspects of glycolipid metabolism during chronic renal insufficiency. Effects of dialytic treatments of short duration (3-4 hours on alternate days)].

The main indices of glycolipid metabolism were examined during and after dialysis in 11 patients receiving chronic treatment. Each dialysis period lasted 3-4 hr and was carried out on alternate days with individual machines and Coil UF2, Coil UF100 and Dasco SP75 dialysers. The liquid contained 35 mEq/l sodium acetate and 2 g glucose and flowed at 500 cc/min. Heparin was injected in the arterial line in a single initial dose. During treatment, there was an increase in free fatty acids and a decrease in serum triglycerides. Blood sugar and insulin were unchanged. The first 4 hr after treatment were marked by decreased fatty acid and increased trigylceride values. Blood sugar and insulin were again constant. The part played by sodium acetate and heparin in these changes is discussed.

[Aspects of glycolipid metabolism in chronic renal insufficiency. Effects of intravenous glucose loading].

The behaviour of blood sugar, insulin plasma free fatty acids and glycerol was studied at various times after intravenous glucose loading in patients with chronic renal insufficiency and normal subjects. Conard's K (glycide assimilation) coefficient was also determined. A statistically significant difference was observed between the two groups in the case of the K values only. No difference was noted in the case of the other parameters. The existence of two distinct groups within the subjects with chronic insufficiency, one with normal and one with altered K values, was also noted. The main physiopathological mechanisms probably responsible for this are discussed. It is considered that glucose loading is less sensitive i.v. than per os in the study of glycolipid metabolism in chronic renal insufficiency.

Dialysis time and the metabolism of carbohydrates and lipids.

The present paper reports some aspects of glycolipid metabolism observed during and after dialysis of varying duration, and the effects of glucose content in dialysis fluid. Some substances used in dialysis interfere with glycolipid metabolism: heparin (Robinson and French, 1960; Wolff and Wolff, 1960); sodium acetate (Bloch, 1947; Ghosal et al, 1969; Mion et al, 1964); and glucose in high (Leonards et al, 1961; Mendelssonhn et al, 1967) or low concentrations (Drukker et al, 1964; Hagstam et al, 1969) or, more recently, completely eliminated (Alwall et al, 1970; Hubner et al, 1971).
