Of 22 immunomodulatory substances screened 12 were effective in modulating the course of hyperglycemia following low dose streptozotocin treatment. In this animal model diabetes is induced by administration of low doses of streptozotocin (30-40 mg/kg) body weight to male C57BL/6J/Bom, C57BL/KsJ and C3H/He/Bom mice on 5 consecutive days. Conventional immunosuppressants (azathioprine, cyclophosphamide) largely protected from diabetes development. Partial suppression of hyperglycemia was also seen after administration of B. pertussis, fetal tissue extracts, FTS, inosine pranobex, metronidazole and ADA 202-718. The majority of these substances, when applied with another regimen, and TP5 caused enhancement of diabetes. In conclusion, several substances with a therapeutic potential in experimental diabetes have been identified. Those with little risk of side-effects may deserve further analysis.

A survey was conducted to ascertain to what extent dietitians use techniques cited in the literature considered to affect adherence by patients with non-insulin dependent (Type II) diabetes. A survey instrument listing techniques related to changing behavior, the counseling process, and content of teaching was developed and mailed to 500 members of the ADA Diabetes Care and Education Practice Group. Responses were received from 39% of the sample. For a majority of techniques, data analysis showed statistical association between frequency of use, perceived importance, and adequacy of practitioner training. Dietitians regularly used only 40% of the cited techniques related to changing behavior and the counseling process, but they said most of the items were important. Only half of the items related to the content of teaching were rated as important, and dietitians felt prepared to use only 70% of them. Most dietitians did not teach concepts related to glucose utilization, energy metabolism, and the metabolic role of insulin in diabetes. Those findings suggest that dietitians do not regularly use many techniques considered effective in obtaining dietary adherence of patients with diabetes. Since other studies show compliance is directly influenced by skills of the provider, dietitians could improve cost-effective health care by developing further professional expertise in the area of counseling patients with diabetes.

The effect on plasma glucose concentration of four different, approximately isocaloric breakfasts designed using the American Diabetes Association food exchange lists was studied in eight type II diabetic patients. The meals were estimated to contain similar amounts of carbohydrate, protein, and fat and were given in random order. The plasma glucose responses to the different meals were similar except for one meal. This meal resulted in a greater glucose increase but the latter could be explained by the substitution of banana for orange juice in the meal. Banana contains starch as well as fructose and glucose, whereas orange juice contains glucose, fructose, and sucrose. In regard to the postmeal glucose response, these data indicate that the ADA food exchange list is useful in meal planning, at least for breakfast.

There is an increasing interest on one of the smallest human chromosomes as it is shown by the First International Symposium on the Human Chromosome 20 and by the genetic map prepared by EUROGEN. The conserved part of the long arm of human chromosome 20 is synthenic with the distal part of the mouse chromosome 2 allowing for some analogies between them. Human chromosome 20 contains several important genes for the human pathology. Mutations of one of them, the vasopressin-neurophysin II gene, are responsible for hereditary neurohypophyseal diabetes insipidus. Severe combined immunodeficiency due to adenosin deaminase deficiency is the first human disorder successfully treated by somatic gene therapy. Spongiform encephalopathies are related to mutation and/or polymorphisms of the PRNP amyloid gene. One form of benign familiar neonatal convulsions is mapped to a specific locus on chromosome 20. In some families, maturity onset diabetes of the young (MODY) is caused by alterations of a hypothetical gene closely linked to the ADA locus. Allegile syndrome is often associated with deletions and microdeletions of the short arm of the chromosome. Finally, deletions of the long arm of the chromosome is a frequent finding in several hematologic malignities, specifically in myeloproliferative disorders and myelodysplastic syndromes.

Mutations of the glucokinase gene (chromosome 7p) have been shown to cause some cases of familial maturity onset diabetes of youth (MODY) but few, if any, cases of late onset familial Type 2 diabetes. A further single large pedigree with MODY has shown linkage to a marker for the adenosine deaminase gene (ADA, chromosome 20q), although the diabetes susceptibility gene at this locus has not been identified. We have studied members of 19 families with familial Type 2 diabetes (including 10 European families, 6 families from the Indian subcontinent, and 3 families of Afro-Caribbean origin), 2 of which were of MODY type (and both European), with a glucokinase marker and a marker linked to ADA, to examine whether glucokinase, or the unknown defect on chromosome 20, are implicated in diabetes in our pedigrees. Several models were constructed for standard two-point linkage analysis. Glucokinase is not the cause of diabetes in all of these families but was excluded in only one MODY family. It was possible to exclude both loci in the second MODY pedigree. No evidence was found of linkage to either marker in this multi-ethnic population under the models used. At least one further locus is involved in determining susceptibility to MODY.

Eight subjects (Ss) with non-insulin-dependent diabetes (NIDDM) monitored their stress, blood glucose (BG), food intake, activity (via pedometer), mood, and coping responses for 8 days. They alternated 2 daily, self-selected ADA food-exchange diets to control for the effects of stress on adherence to diet. BG was significantly higher on high-stress compared to low-stress days. This effect was at least partially mediated by the effect of stress on activity; Ss were significantly less active on high-stress days. Further analyses suggested idiosyncratic relationships between mood and BG, and some evidence was found to suggest a relation between stress, coping, and BG.

Multiple highly polymorphic markers have been used to construct a genetic map of the q12-q13.1 region of chromosome 20 and to map the location of the maturity-onset diabetes of the young (MODY) locus. The genetic map encompasses 23 cM and includes 11 loci with PIC values > .50, seven of which have PICs > .70. New dinucleotide repeat polymorphisms associated with the D20S17, PPGB, and ADA loci have been identified and mapped. The dinucleotide repeat polymorphisms have increased the PIC of the ADA locus to .89 and, with an additional RFLP at the D20S17 locus, the PIC of the D20S17 locus to .88. The order of the D20S17 and ADA loci determined genetically (cen-ADA-D20S17-qter) was confirmed by multicolor fluorescence in situ hybridization. The previously unmapped PPGB marker is closely linked to D20S17, with a two-point lod score of 50.53 at theta = .005. These markers and dinucleotide repeat markers associated with the D20S43, D20S46, D20S55, D20S75, and PLC1 loci and RFLPs at the D20S16, D20S17, D20S22, and D20S33 have been used to map the MODY locus on chromosome 20 to a 13-cM (sex averaged) interval encompassing ADA, D20S17, PPGB, D20S16, and D20S75 on the long arm of chromosome 20 and to create a genetic framework for additional genetic and physical mapping studies of the region. With these multiple highly polymorphic loci, any MODY family of appropriate size can be tested for the chromosome 20 linkage.

Abnormalities of plasma lipids are highly prevalent in both types of diabetes, but there are important quantitative and qualitative differences that this paper reviews. The importance of abnormalities in lipoprotein metabolism as determinant of vascular risk in general population is similar in diabetes, where there is chronic hyperglycemia associated, but it is considered as an independent vascular risk factor. People with IDDM in adequate glycemic control generally have plasma lipid concentrations in normal levels, but in NIDDM, even in good glycemic control, there are another factors associated and usually there are hypertriglyceridemia and total hypercholesterolemia with reduced HDL fraction. Carbohydrate-rich diet increase plasma triglyceride levels and low HDL-cholesterol levels in the majority of studies. Substitute monounsaturated fats in the diet to replace saturated fats lowers total cholesterol and LDL fraction and increase HDL, in addition it acts over others vascular risk factors. These findings were taken into account by ADA and recently revises their 1986 dietary recommendations with the same goals of medical nutrition therapy but with individualized approach appropriate for the personal life style to facilitate adherence to achieve the glycemic, lipid body weight and blood pressure aims with a good quality of live.

In conclusion, South Carolina has a higher prevalence of diabetes compared to the national average. Age is a major factor associated with increased prevalence. African Americans had a disproportionately higher prevalence of diabetes relative to white Americans in South Carolina. Compared to the standards of diabetes care recommended by the ADA, health care practice by people with diabetes and health professionals still needs to be improved. Diabetes communication programs, including diabetes education for people with diabetes and health professional education, continue to be necessary for the improvement of diabetes care.

Metformin often promotes weight loss in patients with obesity with non-insulin-dependent diabetes mellitus (NIDDM). The mechanism may be attributed to decreased food intake. This study has tested the effect of metformin on satiety and its efficacy in inducing weight loss. Twelve diet-treated NIDDM women with obesity were randomly given two dose levels (850 mg or 1700 mg) of metformin or placebo at 0800 for three consecutive days followed by a meal test on the third day on three occasions using a 3x3 Latin square design. The number of sandwich canapes eaten in three consecutive 10-minute periods beginning at 1400 hours was used to quantitate food intake, and the level of subjective hunger was rated just before the sandwich meal with a linear analogue hunger rating scale at 1400 after a 6-hour fast. The prior administration of metformin produced a reduction in calorie intake after each of the two doses of metformin treatment. The 1700-mg metformin dose had the most marked appetite suppressant action. Similarly, hunger ratings were significantly lowered after metformin, and the effect was most pronounced after the administration of 1700 mg of metformin. To assess the efficacy of metformin in reducing bodyweight, 48 diet-treated NIDDM women with obesity who had failed to lose weight by diet therapy were first placed on a 1200-kcal ADA (American Diabetes Association) diet before being randomized to receive either metformin (850 mg) or placebo twice daily in a double-blind fashion for 24 weeks. A 4-week single-blind placebo lead-in period preceded and a 6-week single-blind placebo period followed the 24-week double-blind treatment period. Subjects treated with metformin continued to lose weight throughout 24 weeks of treatment; their mean maximum weight loss was 8 kg greater than that of the placebo group, with corresponding lower HbA1C and fasting blood glucose levels at the end of the active treatment period. These results indicate that metformin decreases calorie intake in a dose-dependent manner and leads to a reduction in bodyweight in NIDDM patients with obesity.
