Effectiveness of an uninterrupted procedure to transfer adolescents with Type 1 diabetes from the Paediatric to the Adult Clinic held in the same hospital: eight-year experience with the Parma protocol.

This paper reports an 8-yr retrospective study on the effects of an uninterrupted procedure of transition of 73 adolescents with Type 1 diabetes from the Paediatric to the Adult Clinic held in the same hospital. Interviewed patients had a mean age of 21.0+/-0.95 yr at transition. Patients were satisfied with the information received before transition (100%), and appreciated being introduced to the adult physician prior to being transferred (92%), and having found their paediatrician during the first visit at the Adult Clinic (100%). Consensus for transition was attained after 2-4 consultations in 66.6% of patients. Seventy-nine percent of patients considered 20 yr of age as an appropriate age to be transferred. Patients confirmed to have found at the Adult Clinic: privacy (85%), confidentiality (95%), short waiting times (78%), informal atmosphere (100%), and the same consultant (100%). Only 3% of patients tried to go back to the Paediatric Clinic but they were discouraged. Clinic attendance rate ranged between 92 and 100%. We consider that the key factors for a successful process of transition from a Paediatric to an Adult Clinic are: age at transfer around 20 yr, smooth movement within the same hospital, consensus of patients and their parents, prior personal contact with the adult physician, paediatrician attendance at the first visit at the adult service and his unambiguous role against all attempts to go back to the paediatric service and, finally, the availability of the same physician at out-patient clinic visits.

[Lp(a) and the cardiovascular risk in dyslipidemia subjects].

In this paper the presence of a correlation between plasma Lp(a) levels and peripheral vascular disease (PVD) and/or coronary heart disease (CHD) was investigated in 20 dyslipidaemic patients (10 males and 10 females, well matched for age, type of hyperlydaemia and other CVD risk factors). Lp(a) plasma levels, ECG and carotid and femoral arteries duplex ultrasonography were performed in all the patients. No difference in plasma Lp(a) levels between patients without and with carotid and femoral arteries stenotic lesions was observed. On the contrary Lp(a) was significantly higher in patients with ECG signs of coronary ischaemic heart diseases than in patients with normal ECG. These observations confirm the importance of Lp(a) as a risk factor for coronary heart disease in dyslipidaemic patients.

Vitreous fluorophotometry and changes in blood-retinal barrier permeability induced by bendazac lysine.

Vitreous fluorophotometry was used to investigate the effect of Bendazac lysine on the blood retinal barrier in 12 insulin-dependent diabetics with mild background retinopathy. The study was a randomized, double blind, cross-over trial, drug versus Placebo. Each treatment period was of 4 months. The vitreous penetration coefficient was reduced by 21% (95% c.i. 12, 30; p = 0.001) by treatment with respect to Placebo.

Lipoprotein(a) and exercise.

Plasma levels of lipoprotein(a), total cholesterol, triglycerides, HDL cholesterol, LDL cholesterol, apoprotein A1 and apoprotein B were assessed in 10 healthy, untrained volunteers subjected to a bicycle ergometric exercise equal to 50% of individual VO2max, followed by increasing loads until muscular exhaustion. Blood samples were taken before the exercise, immediately afterwards and then at 12-hourly intervals for a 72 hours period. Subsequently, the same parameters were evaluated for 8 long-distance runners during the XXIII New York Marathon, with blood samples being taken before and after the race, and then after one month of detraining. After the exercise, lipoprotein(a) in untrained subjects began to decrease significantly from the 24th hour on and remained lower than baseline levels up till the 72nd hour. After detraining, lipoprotein(a) in marathon runners increased significantly both with respect to basal values and especially to post-race values. Modifications of the other metabolic parameters evaluated in both tests were negligible and predictable. In the two groups of subjects examined, no correlation was found between lipoprotein (a) and the anthropometrical data and metabolic parameters considered.

Dietary treatment of dyslipidaemias.

Detailed and personalized dietary guidance must be given to subjects recognized as dyslipidaemic and to the parents of high-risk individuals. The diets should be hypolisocaloric with reduced intake of fats (30%) and cholesterol (250-300 mg/day) and with high intake of carbohydrate (55-60%), preferably complex. Dietary fibre intake should be at least 25 g/day.

[Comparison of HbA1c, fructosamine and the main metabolic parameters in a non-insulin-dependent diabetic population].

Our objective was the checking of clinical data obtainable from the assay of some parameters in NID diabetic individuals. To this end, we studied 133 patients--57 males and 76 females, average age 74.36 +/- 1.01 years, 72.6% of which were above 65 years of age. The control population was subdivided as follows: 50 subjects, 26 F and 24 M; average age 71.25 +/- 1.32 years, with normal glucidic tolerance as assessed by OGTT. Current glycemia, average glycemia, fructosamine, glycosylated hemoglobin, triglycerides, LDL-cholesterol and apolipoprotein B were obviously much higher than normal in the individuals admitted to the study. A statistically significant correlation was found between average glycemia, glycosylated hemoglobin, LDL-cholesterol and blood triglycerides (p less than 0.05). No correlation was found between current glycemia, fructosamine and glycosylated hemoglobin. Similarly, serum fructosamine was unrelated to the parameters studied. In our study, fructosamine, glycosylated hemoglobin and current glycemia offered unrelatable data. Hence, in our opinion it is necessary to assay these three parameters contemporaneously for a reliable assessment of metabolic compensation.

[Efficacy of blood lipid normalization and tolerance in dyslipidemic patients treated for 18 months with fibric acid derivatives].

Three groups of hyperlipoproteinemia patients have been submitted to long term treatment (18 months) with bezafibrate, gemfibrate and fenofibrate evaluating efficacy and tolerability of the three drugs. A global improvement of lipemic profile with an increase in protective (HDL, APO-A1) and a reduction in atherogenic factors (TC, LDL, APO-B, TG) has been shown, particularly at the end of the 18 months of therapy. No pathological changes have been observed in SGOT, SGPT, GGT values. Echotomography of biliary tract excluded the development of gallstones during treatment. The Authors can conclude with a positive judgement about use of these drugs in long term treatment of primary hyperlipoproteinemias, resistant to diet alone.

[Etiopathogenetic role of metabolic, circulatory, sex factors and type and duration of diabetes in diabetic retinopathy. Investigation with vitreofluorophotometry].

We have studied metabolic, circulatory and vascular parameters in a group of 57 diabetics (37 affected by IDDM, 20 affected by NIDDM; 35 were males, 22 were females). Goals of present study were: 1) quantitative evaluation of the blood retinal barrier; 2) influence of the metabolic state, blood pressure, sex, type and duration of the diabetes on the ocular conditions; 3) relationship between ophthalmoscopic appearance of the retina and vitreous fluorophotometric recordings. We concluded that: a) ocular alterations depend by lipidic metabolism, blood pressure, sex, type and duration of the diabetes; b) vitreous fluorophotometry has proved a good device for early detection of retinal damages in the diabetic retinopathy.

[Clinical use of pantethine by parenteral route in the treatment of hyperlipidemia].

Recent investigations have confirmed the effectiveness and the excellent tolerability of pantethine, a derivative of pantetheine, an essential part of the acetylation coenzyme CoA, administered P.O., in normalizing the blood lipid concentrations of patients with hyperlipidemias. A group of 18 patients with hyperlipidemias (9 M, 9 F), with an average age of 52.6 years, was submitted to pantethine parenteral treatment. After a 20 days wash-out, pantethine (400 mg/day; BID) was administered intramuscularly, for 20 days. Total cholesterol, triglycerides, HDL-cholesterol, apo A-1 and B lipoprotein, uric acid in serum, glycemia, CBC, B.U.N., creatininemia, E.S.R., SGOT, SGPT, bilirubinemia, cardiac frequency, blood pressure and body weight were controlled before and after treatment. The drug showed to have a therapeutic effectiveness by a rapid and significant improvement in the blood lipid pattern with reduction of total cholesterol, triglycerides and apo-B lipoprotein and increase of HDL-cholesterol and apo A-1 lipoprotein. The tolerability of pantethine at the stated dosage and mode of administration was invariably excellent, with non complaints or visible side effects imputable to the test drug. BUN, creatininemia, glycemia, SGOT, SGPT, bilirubinemia, E.S.R., CBC, cardiac frequency and blood pressure readings showed no noteworthy changes throughout the study.

[Retrospective study on 778 patients with acute myocardial infarct: relation between sex, age and blood lipid picture].

To evaluate the relationship between myocardial infarction and serum lipid levels, 778 patients admitted to the Fidenza Coronary Unit were studied. These patients were divided by sex and into groups by age decade and the frequency of hyperlipidemia was investigated. In the first place the association between myocardial infarction (MI) with hypercholesterolemia, second with hypertriglyceridemias was considered. In addition the population was subdivided in respect to the 3 more frequent types of hyperlipidemia (hypercholesterolemia, hypercholesterolemia and hypertriglyceridemia, hypertriglyceridemia). The results show the presence at a positive correlation between MI and hypercholesterolemia in the younger groups in both sexes, but mainly in female. Similar results are obtained when the correlation between MI and hypertriglyceridemia was considered, but at a lower statistical significance. The statistical analysis of the different types of hyperlipidemia confines the important pathogenetic role of hypercholesterolemia by itself and in association with hypertriglyceridemia. On the other hand hypertriglyceridemia does not show any primary influence on MI, but it acts synergistically with hypercholesterolemia. The strong association of hyperlipidemia and MI in the younger group and in female, documented in this study, confirms the importance of hypercholesterolemia and hypertriglyceridemia as a risk factor in the early development of coronary heart disease.

[Clinical study of a new preparation from plantago seeds and senna pods].

The lack of fiber in the western diet may contribute to the development of several diseases including gastrointestinal disorders; the clinical effects of a new substance (AGIOLAX) made from plantago seeds and senna pods were studied. 100 patients of both sexes, aged from 40 to 60 years (30 with diabetes mellitus, 40 with obesity and 30 with hyperlipidemia) were treated; everyone complained a slowness, of different degree, of normal intestinal transit time or chronic constipation. The experiment was carried out without the use of a control group. Aim of the present study was to investigate the efficacy and tolerability of the product. In addition to the clinical evaluation of the symptoms, laboratory tests were performed. The patients were treated for 3 months with a daily dose of 2 teaspoons every evening. In the majority of the subjects a good clinical response was obtained; 88% of the patients presented a normalization of the gastrointestinal transit time; only 12% of them did not respond satisfactorily to the substance. Further the drug was well tolerated by 86% of the patients. In conclusion the authors report a good efficacy and tolerability of the product; thus they recommend its use in those disorders characterized by slow intestinal transit time and/or constipation.

Effectiveness of long-term treatment with pantethine in patients with dyslipidemia.

A one-year clinical trial with pantethine was conducted in 24 patients with established dyslipidemia of Fredrickson's types II A, II B, and IV, alone or associated with diabetes mellitus. The treatment was well tolerated by all patients with no subjective complaints or detectable side effects. Blood lipid assays repeated after 1, 3, 6, 9, and 12 months of treatment revealed consistent and statistically significant reductions of all atherogenic lipid fractions (total cholesterol, low-density lipoprotein cholesterol, and apolipoprotein B) with parallel increases of high-density lipoprotein cholesterol and apolipoprotein A. The results were equally good in patients with uncomplicated dyslipidemia and in those with associated diabetes mellitus. The authors conclude that pantethine (a drug entity related to the natural compound, pantetheine) represents a valid therapeutic support for patients with dyslipidemia not amenable to satisfactory correction of blood lipids by diet alone.

[Hyperlipidemia, diabetes and atherosclerosis: efficacy of treatment with pantethine].

The hypolipidemizing effects of Pantethine were investigated by the Authors in 37 hypercholesterolemic and/or hypertriglyceridemic patients. Of these, 21 were also diabetic, in a satisfying glucidic compensation, in order to verify the action of this drug also in this metabolic condition. The study was carried out for three months and during this period the patients were given Pantethine at the dose of 600 mg/die orally. At the 30th, the 60th, the 90th day of treatment the following parameters were controlled: cholesterolemia, HDL cholesterol, apolipoproteins A and B, triglyceridemia, systolic and diastolic arterial pressure, uricemia, body weight. Thirty days after suspending the treatment, the parameters were controlled again to detect a possible "rebound" effect. The results were analyzed on the whole case-record, subdividing the patients in dislipidemic and diabetic-dislipidemic, and on the basis of the Fredrickson's classification. Pantethine induced in all groups a quick and progressive decrease of cholesterolemia, triglyceridemia, LDL cholesterol and Apolipoproteins B with increased HDL cholesterol and Apolipoproteins A. After suspending the treatment, there is a clear inversion of the state of these parameters. The Authors conclude that the present work shows that Pantethine, a natural and atoxic substance, an important component of Coenzyme A, is efficacious in determining a clear tendency towards normalization of the lipidic values.

[Serial determination of HbA1 or the oral glucose test in the adequate evaluation of fetal growth?].

The authors compared sequential HbA1 levels with the results obtained by oral glucose tolerance test (O.G.T.T.) with the purpose of detecting the confidence limit of each test regarding the glucose control in pregnant women. HbA1 detection showed more sensitivity than O.G.T.T. in detecting maternal impaired glucose control and in distinguishing between a metabolic or a genetic feto-neonatal macrosomia.

[Dietary fiber and OGTT: blood sugar variations after administration of a new purified glucomannane].

After having stressed the importance of fibres in the nutritional field, pointing out the inverse relationship between vegetal fibres consumption in various populations and diffusion of many diseases of the so-called "industrialized" societies (such as obesity, diabetes, dyslipidemias, atherosclerosis, cholelithiasis, cancer of the colon, etc.), the Authors report their experiment on a new experimental product based on glucomannane purified (PRL). The present study was carried out on 24 obese subjects (5 males and 19 females). The patients, normoglycemics in their basic condition, were submitted to OGTT with 75 g of glucose in the morning before eating and were subdivided into two groups, the first (Group A) characterized by the sequence OGTT + placebo; after a few days, by another OGTT + experimental product; the second characterized by the inverse sequence. Four tablets (glucomannane purified 5,2 g) and four tablets of placebo was the posology employed. The evaluation of the possible action of the product in reducing or slowing down the intestinal absorption of glucose was the aim of the research. The results obtained show that the administration of the product under study has led to a sharp decrease of the average glycemic values with variations per cent ranging from 13% to 16% in Group A, from 10% to 11% in Group B and from 7% to 12% in the two groups considered on the whole. In conclusion, the Authors wish an increased diffusion of dietary fibres and particularly of the glucomannanes in all those dysmetabolic forms having at their bases an unbalanced, hypercaloric alimentation, rich in refined aliments and poor in fibres.

[Clinical study of the use of a deproteinized guar flour in the treatment of obesity].

The Authors have studied an experimental product (L. G. 140/S), based on GUAR GUM, to establish its effectiveness and tolerability as a dietetic support in the treatment of obesity. The clinical research work has been conducted on 21 obese subjects (18 females and 3 males) aged 17 to 58 and treated with a hypocaloric and hypoglycemic diet. This preparation has proved useful in helping the patients to conform to the dietary restrictions and/or in normalizing their intestinal transit. No objective or subjective symptoms certainly referable to this preparation have been observed. The administration of the product has been interrupted for precautionary reasons in some cases, since it was not indispensable. Considering the good results they have obtained in terms of tolerability and agreeableness of this product, the Authors conclude that it can be considered a useful support to the restrictive dietary regimen, which is still considered - together with physical activity - the only sound and effective remedy in the treatment of obesity.
