Children with newly diagnosed insulin dependent diabetes mellitus have increased levels of cow's milk antibodies.

We studied antibodies to cow's milk, beta-lactoglobulin and gliadin with enzyme-linked immunosorbent assay in the sera of 91 children with insulin dependent diabetes mellitus (IDDM); 36 of them were newly diagnosed. The children with newly diagnosed IDDM had significantly higher levels of IgA antibodies to cow's milk and to beta-lactoglobulin, and IgG antibodies to beta-lactoglobulin than 100 age-matched controls. We infer that either the pattern of cow's milk consumption is altered in children who will have IDDM, or their immunological reactivity to proteins in cow's milk is enhanced, or the permeability of their intestines to cow's milk protein is higher than normal.

Relationship between serum insulin autoantibodies, islet cell antibodies and Coxsackie-B4 and mumps virus-specific antibodies at the clinical manifestation of type 1 (insulin-dependent) diabetes.

In order to elucidate the possible relationship between insulin autoantibodies (IAA), conventional (ICA-IgG) and complement-fixing (CF-ICA) islet cell antibodies and Coxsackie-B4 and mumps virus-specific antibodies (IgG, IgM and IgA classes), we studied 194 children and adolescents with newly diagnosed Type 1 (insulin-dependent) diabetes. Sixty-one (31.4%) of the subjects were IAA-positive at diagnosis and 73.

Insulin autoantibodies at the clinical manifestation of type 1 (insulin-dependent) diabetes--a poor predictor of clinical course and antibody response to exogenous insulin.

To study the possible clinical significance of the appearance of insulin autoantibodies prior to the diagnosis of Type 1 (insulin-dependent) diabetes, and their value in predicting the antibody response to exogenous insulin, we observed 46 newly diagnosed diabetic children and adolescents over the year following diagnosis for the occurrence and duration of clinical remission, daily insulin dose, metabolic control, residual B-cell function, insulin-binding antibodies and conventional as well as complement-fixing islet cell antibodies. Insulin-binding antibodies were determined using both monoiodinated human and porcine insulin. Sixteen children (34.

Three-year tracking of serum fatty acids in Finnish boys and girls.

The composition of fatty acids in serum lipids has been shown to reflect the quality of dietary fat. In order to examine the long-term stability (tracking) of the serum (and hence dietary) fatty acid composition serum cholesteryl ester fatty acids were analysed by gas chromatography in a randomly selected population sample of 1029 Finnish boys and girls aged 3, 6, 9, 12, 15 and 18 years, and again from the same individuals 3 years later. The tracking was evaluated by calculating linear correlation coefficients for the percentages of individual fatty acids between the 2 time points.

Dietary survey of Finnish adolescent diabetics and non-diabetic controls.

Food consumption data of 152 diabetic and 74 non-diabetic adolescents were collected by means of two 48 h recall interviews. The nutrient density of the diet was systematically higher for the diabetics than the controls. The energy intake from protein was higher for the diabetics (18% vs.

Serum antibody-bound insulin as a measure of insulin antibodies in diabetic children.

The usefulness of the measurement of serum antibody-bound and total immunoreactive insulin (IRI) concentrations in the assessment of insulin antibodies was evaluated in a material comprising 49 insulin-dependent diabetic children with a mean age at onset of 8.6 years (range 0.8-16 years) treated with highly purified porcine insulins.

Glycosaminoglycans and apolipoproteins B and A-I in human aortas. Chemical and immunological analysis of lesion-free aortas from children and adults.

To study changes in the contents of plasma lipoproteins in human arteries with age and the relationship of lipoproteins with other arterial constituents, we analyzed the contents of apolipoproteins B (apo B) and A-I (apo A-I), free and esterified cholesterol, and glycosaminoglycans (GAG) in lesion-free aortic intimas of 30 children and adults. The content of apo B increased significantly with age, whereas that of apo A-I remained relatively constant. Apo B and apo A-I had significant positive correlations with the content of chondroitin sulphates A + C (CS A + C), which comprised 35% to 47% of the aortic GAG.

Beneficial effects of palatable guar and guar plus fructose diets in diabetic children.

This randomized cross-over study evaluates the effects of extended, guar and guar + fructose diets on the metabolic balance of children with insulin-dependent diabetes mellitus (IDDM). We studied 22 children; mean age 12.2 years, mean duration of diabetes 4.

Insulinotropic activity in the serum of obese and nonobese infants and children.

The ability of a serum fraction, mol wt 1000-5000, to stimulate insulin release in vitro was studied in 123 obese and normal weight children aged 0-17 yr. The sera were fractionated by serial molecular filtration after treatment with urea. Stimulation of insulin release was determined with a bioassay using isolated rat islets in perifusion.

Geographic origin of the family as a determinant of serum levels of lipids in Finnish children.

Children in the eastern part of Finland have higher serum total and low-density lipoprotein (LDL) cholesterol levels than children in the western part of the country. This is consonant with the high mortality rate for coronary heart disease in eastern Finland. Eastern and western Finns are assumed to have different geographic origins; because of this we divided into groups 630 newborns and 3554 children and adolescents according to their grandparents' birthplace, which, in Finland, reflect the origins of the children.

Evidence of an accelerated B-cell destruction in HLA-Dw3/Dw4 heterozygous children with type 1 (insulin-dependent) diabetes.

The possible association between residual B-cell function and specific HLA antigens in Type 1 (insulin-dependent) diabetes was studied in a cross-sectional series of 144 diabetic children and adolescents, as well as in a prospective series of 44 newly diagnosed diabetic subjects who were observed for the initial 2 years of their diabetes. In the cross-sectional study, the HLA-Dw3/Dw4 heterozygotes had a lower mean serum C-peptide concentration during 1980, 0.03 +/- 0.

Celiac disease in insulin-dependent diabetes mellitus.

Jejunal biopsy was performed without selection in 110 of 201 children with insulin-dependent diabetes mellitus; serum reticulin antibody, antigliadin antibody by enzyme-linked immunosorbent assay, and serum IgA were studied in all 201 children. Seven children had severe jejunal villous atrophy, giving a prevalence of celiac disease of at least 3.5%.

Relation between insulin antibody and complement-fixing islet cell antibody at clinical diagnosis of IDDM.

To test the hypothesis that insulin-binding antibodies (IBAs) appearing in the circulation before insulin treatment are markers of beta-cell damage, we studied the prevalence of IBAs and both conventional (IF-ICAs)-and complement (CF-ICAs)-fixing cytoplasmic islet cell antibodies in 60 newly diagnosed diabetic children with a mean age of 9.5 yr. Seventeen (28.

Biochemical composition of coronary arteries in Finnish children.

To study the early features of atherosclerosis, we analyzed coronary artery intima medias from 63 boys and 30 girls who were newborn to 15 years old at the time of accidental death. Fatty streaks were found in five boys and one girl and, with one exception, were not present until the second decade of life. From birth there was a continuous increase in esterified cholesterol (EC) and a two- to threefold rise in free cholesterol and phospholipid.

Fatty acid composition of serum cholesteryl esters in relation to serum lipids and apolipoproteins in 3-18-year-old Finnish children and adolescents.

Serum cholesteryl ester (CE) fatty acids, serum lipids and apolipoproteins were analysed from 1348 Finnish children aged from 3 to 18 years. The study was part of a comprehensive survey of coronary heart disease risk factors and their determinants in Finnish children and adolescents. The percentage of CE linoleate (18:2) had significant negative correlations with the serum concentrations of total and LDL cholesterol, triglycerides as well as apo B.

Serum insulin-releasing activity and the Prader-Willi syndrome.

Pathogenesis and etiology of the various clinical features of the Prader-Willi syndrome (PWS) are not completely understood. There is evidence suggesting a hypothalamic abnormality leading to hypogonadism in this syndrome. To test the possible hypothalamic involvement in the pathogenesis of obesity in these patients we studied the sera of 5 patients with PWS for insulin-releasing activity of possible hypothalamic origin.

Fatty acid composition of serum cholesteryl esters in 3- to 18-year-old Finnish children and its relation to diet.

The composition of fatty acids in serum cholesteryl esters (CE) was analyzed gas chromatographically in 1348 boys and girls aged from 3 to 18 yr. A dietary survey was carried out simultaneously using the 48-h recall method. The dietary P/S ratio had highly significant correlations with CE fatty acids: positive with linoleate (0.

Geographic differences in the risk of insulin-dependent diabetes mellitus: the importance of registries.

There are marked geographic differences in the incidence of insulin-dependent diabetes mellitus (IDDM); for example, children in countries such as Finland are over 35 times more likely to develop IDDM than children in Japan. An understanding of the reasons for the geographic differences is likely to be important for understanding and, hopefully, preventing IDDM. There are problems, however, because of the lack of registries with adequate standardization.

The epidemiology of insulin-dependent diabetes mellitus (IDDM) in Finland and in northern Europe.

The incidence and prevalence of IDDM are high by international standards in all Nordic countries, and Finland has the highest incidence and prevalence figures of the disease in the world. During the period 1970-1980, the mean annual incidence (per 100,000) in 0-14-yr-old children was 28.6 in Finland, 22.

An analysis of epidemiological data in HLA-typed diabetic children.

To clarify the heterogeneity of Type 1 (insulin-dependent) diabetes mellitus, differences between patients with different HLA risk antigens were investigated with regard to sex, age at diagnosis, season of year and calendar year at diagnosis of the disease. The study consisted of 293 HLA-typed patients from the Department of Paediatrics, University of Oulu, Oulu, Finland. HLA-Dw2 was extremely rare among diabetic patients, whereas Dw3 and Dw4 were associated with increased risk in this as in other series.

Two cases of acute carbon monoxide poisoning with delayed neurological sequelae after a "free" interval.

Two cases are presented to illustrate the delayed neurological complications which may follow carbon monoxide (CO) poisoning, the mechanisms of which are not well known and which do not seem to be recognized widely enough to safeguard patients. Broad discussion is needed to determine how cases of CO exposure/poisoning should best be handled if sequelae are to be avoided.
