    Urinary albumin excretion in a representative sample of 679 patients with Type I (insulin-dependent) diabetes, 18 to 50 years of age, was investigated. Patients on antihypertensive therapy were excluded. Urinary albumin excretion was examined in one 24 hour urine sample using an ELISA technique....... Twenty-three per cent of the patients had microalbuminuria, i.e., 30-300 mg albumin/24 h. The prevalence of microalbuminuria was independent of sex, age, insulin dose and diabetes duration. In the majority of those cases in which microalbuminuria was found during the first 10 years of diabetes......, the concentrations were in the lower range, i.e., 30-50 mg/24 h. The prevalence of incipient nephropathy (urinary albumin excretion in a single urine sample of 51-300 mg/24 h) increased with diabetes duration. In patients with incipient nephropathy hemoglobin A1c tended to be, and blood pressure was, elevated...

    Background • There is a paucity of information on alternative, nutrition-based treatments for insulin-dependent diabetes. Primary Study Objective • This case report provides detailed information on the nutrition-based treatment of a man with insulin-dependent diabetes. Methods/Design • This is a single case report taken from the author's private practice. Setting • The treatment was provided at a private office in New York, NY, USA. Participants • A single patient in the author's practice is reported. Intervention • The patient was treated with a combination of pancreatic enzymes, supplements and nutrients, and cleansing and detoxification procedures, plus amber lenses for severe insomnia. Primary Outcome Measures • The outcome measures were patient self-report of symptoms, overall well-being, and function at work and in leisure time; observation of the patient by the physician; and blood work. Results • The patient described dramatic, sustained improvement in terms of symptoms, function, well-being, and life satisfaction. Improvement in blood sugar control was documented by blood work. Conclusion • The complex, tailored nutritional protocol combined with detoxification procedures, resulted in marked improvement in a patient who had been treated by numerous different physicians without benefit prior to his consulting with the author.

  4. Lactation in insulin-dependent diabetes.

    The ability of insulin-dependent diabetic (IDDM) women to breast-feed has been documented, however, there is little information concerning milk composition or factors that influence successful breastfeeding. Placental lactogen and prolactin levels can be normalized during pregnancy with good metabolic control. These hormones affect the readiness of the mammary gland for lactation. Prolactin maintains mammary gland insulin receptors to ensure anabolism. Lactation in IDDM women may be influenced by hyper- or hypoglycemia as women balance their insulin needs. Milk from diabetic animals has decreased lactose, fat, protein and volume and these effects can be reversed with insulin administration. Mature breast milk of IDDM women has increased glucose and sodium and mammary gland lipid metabolism may be impaired. Milk lactose and citrate, markers of lactogenesis II, suggest delayed lactation occurs in diabetic women. Many factors may influence lactation success and breast milk composition of IDDM women. Some of these include: method of delivery, feeding frequency, fetal condition, gestational age, mastitis incidence, metabolic control and maternal dietary intake. Lactation management of the IDDM woman must address these factors.

  7. Aprotinin induced lipohypertrophy and glomerulonephritis in an insulin dependent diabetic.

    Science.gov (United States)

    Dandona, P; Mier, A; Boag, F; Chappell, M; Beckett, A G

    1985-07-01

    In an insulin dependent diabetic who was hyperglycaemic and ketotic despite 3,000 u of insulin injected subcutaneously in 2 divided doses daily, 50 u of intravenous insulin infused over 24 hr restored normal glucose homeostasis. A combination of insulin (800 u) and aprotinin (10,000 u) given twice daily also produced adequate glucose homeostasis for a period of 12 months. The patient then developed local hypertrophy of subcutaneous tissue at the injection site and her diabetic control deteriorated. Non-selective proteinuria followed and she developed nephrotic syndrome. Renal biopsy revealed a membraneous glomerulonephritis with subepithelial immune complexes, appearances consistent with a drug-induced glomerulonephritis. Withdrawal of aprotinin led to a gradual remission of nephrotic syndrome and proteinuria over several months. During this period, her diabetes was well controlled with continuous subcutaneous infusion of insulin at a dose of 500 u/24 hr. This case report demonstrates: the effective use of aprotinin for prolonged periods in insulin dependent diabetics with abnormal absorption of subcutaneously injected insulin; aprotinin induced lipohypertrophy which was not observed when insulin was injected alone; aprotinin-associated glomerulonephritis and nephrotic syndrome; the effective use of CSII--at higher insulin doses--in such patients with subcutaneous malabsorption of insulin.

    The difference in the acute metabolic change in ketone bodies between patients with insulin-dependent diabetes mellitus (IDDM) and non-insulin-dependent diabetes mellitus (NIDDM) was investigated in this study. The subjects employed were 7 patients with IDDM losing residual insulin secretion and 7 patients with NIDDM matched to the former patients for age, body mass index, duration of diabetes, daily insulin dosage, fasting plasma glucose and HbA1c. Blood samples were drawn at 3A.M. and 7A.M. on the same day, and plasma glucose, acetoacetic acid (AcAc), 3-beta-hydroxybutylic acid (3-OHBA), free fatty acid (FFA), glycerol, cortisol and growth hormone (GH) concentrations were determined. Plasma total ketone bodies (AcAc and 3-OHBA), 3-OHBA and FFA concentrations at 7A.M. were significantly higher in the patients with IDDM than in those with NIDDM (p ketone bodies, AcAc and 3-OHBA concentrations were also more significantly elevated in the patients with IDDM than in those with NIDDM. It was observed that the ratio of 3-OHBA was more than 2.0 in all of the patients with IDDM and less than 2.0 in all of the patients with NIDDM, the difference being significant with p < 0.001.(ABSTRACT TRUNCATED AT 250 WORDS)

    To evaluate changes of pancreatic size with aging in control subjects and in non-insulin- dependent diabetic patients. Two groups of non-insulin-dependent diabetic patients were examined; one had been treated with an oral hypoglycemic agent(n=59), and the other with insulin(n=56). The CT findings of 175 patients without clinical evidence of pancreatic disease were included as a normal control. In control subjects, pancreatic size and age correlated. The pancreas was smaller in non-insulin-dependent diabetics than in control subjects and smaller in insulin- treated non-insulin-dependent diabetics than in non-insulin treated patients. The pancreas was smaller in non-insulin-dependent diabetic patients than in control subjects within the same age range.

  10. HLA and insulin-dependent diabetes: an overview.

    Science.gov (United States)

    Svejgaard, A; Ryder, L P

    1989-01-01

    The present knowledge of the HLA system and its biological function is summarized as a basis for the subsequent discussion of the associations between this system and insulin-dependent diabetes (IDDM) and some mechanisms that may explain them. Although the serologically detectable DR determinants are still the most handy markers, there is now increasing evidence from studies of restriction enzyme fragment length polymorphism (RFLP) in IDDM that DQ determinants may play a primary role in causing susceptibility and/or resistance to this disease. Thus, it is now evident that about 90% of DR4-positive diabetics carry the DQw8 determinant present in only about 65% of DR4-positive controls. Most recently, it has been claimed that an aspartic acid in position 57 of the DQB1 (DQ-beta-1) chain confers resistance to IDDM. Although this may be true, it does not explain the disproportionate decrease of DR2 or the particularly high risk of DR3/4 heterozygotes, which is still good evidence that several HLA genes are involved. Because Class II antigens show the strongest associations, the most plausible hypothesis about the mechanism(s) involves specific presentation of as yet unknown antigenic peptides to T-helper lymphocytes, which may induced the formation of both anti-islet cell antibodies and T-cytotoxic lymphocytes capable of destroying beta cells. However, T-suppressor lymphocytes also may be involved. If this hypothesis is correct, the most urgent task is to define the antigenic peptides in question, whether they are environmental (e.g., viral) or autologous.

    Diabetes is associated with several complications such as retinopathy, nephropathy, neuropathy and cardiovascular diseases. Currently, insulin is the main used medication for management of insulin-dependent diabetes mellitus (type-1 diabetes). In this metabolic syndrome, in addition to decrease of endogenous insulin, the plasma level of connecting peptide (C-peptide) is also reduced due to beta cell destruction. Studies in the past decade have shown that C-peptide is much more than a byproduc...

    1987-02-01

    Non-insulin-dependent diabetes mellitus (NIDDM) is a complex disease that lasts a lifetime. It can be controlled but not cured. Treatment involves extensive changes in the patient's lifestyle, particularly in the areas of diet and exercise, which can often result in noncompliance with treatment regimens. Efforts to bring about these lifestyle changes usually require an enormous amount of time and attention on the part of the physician, and thus, are best carried out with the help of a diabetes education team. An ideal team would consist not only of the physician, patient, and family, but also a diabetes educator, a nutritionist or dietitian, an exercise therapist, a psychologist or social worker, a podiatrist, and an ophthalmologist or retinologist. A smaller number of team participants can offer a viable alternative by doubling up discipline areas, and by using interested members of the community as a referral source.

    Full Text Available 20 children with the insulin dependent diabetes have been vaccinated with pneumo 23 against pneumococcal infection during the two week prevention course by immunomodulating spray IRS 19. Topical lysate was prescribed on the day of vaccination in the season, immediately preceding the flu epidemy. Before application of topical lysate, as well as in a month and in 3 months after the pre vention course was over, the researchers evaluated the biocenose indices of nasal and fauces cavity mucosa. Alongside, otorhinolaryngologist examined the children. IRS 19 prescription helped to avoid the emergence of intercurrent diseases during the post vaccinal period, in the meantime, it led to the reduction of pathogenic flora sowing, intensity of the inflammatory changes in the nasal pharynx and fauces. Vaccination against pneumococcal infection and combined application of Pneumo 23 with IRS 19 among children with the insulin-dependent diabetes contributed to the reduction of frequency and severity of the respiratory ingections if compared with the similar indices of 43 patients with diabetes, who did not receive immunization.Key words: children, insulin dependent diabetes, chronic tonsillitis, tissue immunity, immunoregulatory spray, vaccine against pneumococcal infection.

    In neonates, persistent hyperinsulinemic hypoglycemia(PHH) is associated with nesidioblastosis. In adults, PHH is usually caused by solitary benign insulinomas. We report on an adult patient who suffered from insulin-dependent diabetes mellitus, and subsequently developed PHH caused by diffuse nesidioblastosis. Mlutations of the MEN1 and Mody 2/3 genes were ruled out. Preoperative diagnostic procedures, the histopathological criteria and the surgical treatment options of adult nesidioblastosis are discussed. So far only one similar case of adult nesidioblastosis subsequent to diabetes mellitus Ⅱ has been reported in the literature. In case of conversion of diabetes into hyperinsulinemic hypoglycemia syndrome,nesidioblastosis in addition to insulinoma should be considered.

    Diabetes is associated with several complications such as retinopathy, nephropathy, neuropathy and cardiovascular diseases. Currently, insulin is the main used medication for management of insulin-dependent diabetes mellitus (type-1 diabetes). In this metabolic syndrome, in addition to decrease of endogenous insulin, the plasma level of connecting peptide (C-peptide) is also reduced due to beta cell destruction. Studies in the past decade have shown that C-peptide is much more than a byproduct of insulin biosynthesis and possess different biological activities. Therefore, it may be possible that C-peptide deficiency be involved, at least in part, in the development of different complications of diabetes. It has been shown that a small level of remaining C-peptide is associated with significant metabolic benefit. The purpose of this review is to describe beneficial effects of C-peptide replacement on pathological features associated with insulin-dependent diabetes. Also, experimental and clinical findings on the effects of C-peptide on whole-body glucose utilization, adipose tissue metabolism and tissues blood flow are summarized and discussed. The hypoglycemic, antilipolytic and vasodilator effects of C-peptide suggest that it may contribute to fine-tuning of the tissues metabolism under different physiologic or pathologic conditions. Therefore, C-peptide replacement together with the classic insulin therapy may prevent, retard, or ameliorate diabetic complications in patients with type-1 diabetes.

    Diabetes is a serious medical and financial burden on western societies. It is the seventh leading cause of death in the United States and Canada. The disease is due to a primary defect in glucose tolerance and carbohydrate metabolism resulting from either a deficiency of insulin (Insulin-dependent (type I) diabetes mellitus - IDDM) or a state of insulin resistance (Non-insulin-dependent (type II) diabetes mellitus - NIDDM). NIDDM comprises greater than 80% of total diabetic cases. Associated with the primary metabolic defects are equally deleterious secondary complications affecting the renal, ocular, nervous and cardiovascular systems. The cardiovascular complications account for a major proportion of diabetic mortality. As such, it is of paramount importance to develop or find an animal model expressing complications homologous to the human condition. Many models of NIDDM are available to the diabetic researcher but choosing an accurate one can be difficult. The following compares the advantages and limitations of one such model, the JCR:LA-cp rat to other NIDDM models commonly used today.

    A 40-year-old woman with insulin-dependent diabetes mellitus was treated successfully with phototherapy for a seasonal affective disorder. Following sessions of phototherapy she developed hypoglycaemias and required less insulin. A review of the literature showed that melatonin has an inhibiting effect on insulin sensitivity. The melatonin secretion, which is suppressed by phototherapy, may cause an immediate decrease in the plasma glucose levels. This decrease may well be important for patients with insulin-resistant diabetes mellitus and seasonal affective disorder.

    Dive medicine bodies worldwide recognise that, with comprehensive screening and careful management, people with insulin-dependent diabetes (IDDM) can dive safely. Despite this, people with IDDM in Australia are generally denied access to dive training, an out-dated status quo that is not acceptable to the Australian diabetes community. This paper reflects upon the important advocacy work that has been done to progress this issue, and what is still required to open up access and bring Australia into line with more flexible and supportive international standards.

    The development and progression of diabetic retinopathy in African Americans with insulin-dependent diabetes mellitus is not known. Two hundred subjects with insulin-dependent diabetes mellitus with duration of diabetes 16 years or less at first visit were studied; 58 were African Americans and 142 were whites. All had gradable stereoscopic color fundus photographs (seven standard fields) from at least two visits (mean time between first and second visit was 4.1 years). Subjects with hemoglobinopathy or proliferative retinopathy or subjects who had evidence of treatment for proliferative retinopathy at first visit were excluded. Masked grading of photographs was conducted using the modified Airlie House classification scheme. African Americans were older, heavier, had higher systolic blood pressure (all P < .05), and marginally higher hemoglobin A1 (HbA1) values (P = .06) than the whites at first visit. African Americans had a lower rate of two steps or more progression from preexistent retinopathy (19%) than whites (43%). Progression to proliferative retinopathy or treatment was similar by race. Multivariate analysis predicting development oe progression of retinopathy, while controlling for length of follow-up, found higher HbA1 (odds ratio [OR] = 2.15), longer duration of insulin-dependent diabetes mellitus (OR = 1.69), higher serum creatinine concentration (OR = 1.59), and white race (OR = 2.62) to be independent risk factors. These data suggest a previously unsuspected reduction in the adjusted risk for development and progression of retinopathy in African Americans. The reason for this apparently reduced risk are not known.

  8. Multifactorial Control of Autoimmune Insulin-Dependent Diabetes in NOD Mice: Lessons for IBD

    Directory of Open Access Journals (Sweden)

    Edward H Leiter

    1995-01-01

    Full Text Available Development of autoimmune insulin-dependent diabetes mellitus in nonobese diabetic (NOD mice is an example of a complex multifactorial disease with strong genetic and environmental components. As such, this model may provide insight not only into mouse models of inflammatory bowel disease, but also may provide insight into how the environment may interact with the genome to initiate pathogenesis in humans. NOD mice are characterized by accumulation of unusually high percentages of T lymphocytes in lymphoid organs. Pancreatic beta cell destruction in NOD mice is T lymphocyte-mediated. Complex interactions between the inherently diabetogenic major histocompatibility complex (MHC haplotype of this strain and non-MHC-associated insulin-dependent diabetes susceptibility genes (Idd are required for cytopathic activation of the leukocytic infiltrates in the pancreas (insulitis. Penetrance of the diabetogenic Idd genes is strongly influenced by both dietary and microbiological factors in the environment. Genetic susceptibility is transmitted by hemopoietic stem cells, and specific defects in T immunoregulation have been traced to defects in the development and function of marrow-derived antigen presenting cells. The spontaneous development of diabetes in NOD mice is different from experimentally induced forms of diabetes in mice in several important respects. In addition to the pathognomic development of pancreatic insulitis, the generalized loss of immunoregulatory control of autoreactive T lymphocytes in NOD mice is reflected by development of leukocytic infiltrates into a plethora of organ systems including the submandibular salivary glands, thyroid glands, kidneys and, occasionally, the colon.

  9. The effect of Ramadan fasting on glycaemic control in insulin dependent diabetic patients: A literature review.

    Alabbood, Majid H; Ho, Kenneth W; Simons, Mary R

    Ramadan fasting is one of the five pillars of Islam. People with diabetes are exempted from fasting according to Islamic rules. However, many people with diabetes wish to fast. Physicians are asked frequently by their patients about their ability to fast and the possible impact of fasting on their glycaemic control. Studies about the effect of Ramadan on people with insulin-treated diabetes are scarce. This review aims to provide clinicians with the best recommendations for their patients with insulin-treated diabetes who wish to fast. Four databases (Medline, EMBASE, Scopus and PubMed) were searched using the following MeSH terms and keywords: "insulin dependent diabetes mellitus", "type 1 diabetes mellitus", 'Ramadan' "and" "fasting". In addition, a hand search of key journals and reference lists was performed. Sixteen full text articles were selected for review and critical analysis. All of the included studies except one found improvement or no change in glycaemic control parameters during Ramadan fasting. The incidence of major complications were negligible. Minor hypoglycaemic events were reported in some studies but did not adversely affect fasting. Postprandial hyperglycaemia was a major concern in other studies. However, the incidence of severe hyperglycaemia and diabetic ketoacidosis were trivial. Ramadan fasting is feasible for insulin dependent diabetic patient who wish to fast. Clinicians should advise their patients about the importance of adequate glycaemic control before Ramadan and frequent glucose monitoring during fasting. Certain types of Insulin seem to be more beneficial than other. Copyright © 2016 Diabetes India. Published by Elsevier Ltd. All rights reserved.

    Abnormalities of the renin-angiotensin system have been reported in patients with diabetes mellitus and with diabetic complications. In this study, plasma concentrations of prorenin, renin, and aldosterone were measured in a stratified random sample of 110 insulin-dependent (Type 1) diabetic patients attending our outpatient clinic. Fifty-four age- and sex-matched control subjects were also examined. Plasma prorenin concentration was higher in patients without complications than in control subjects when upright (geometric mean (95% confidence intervals (CI): 75.9 (55.0-105.6) vs 45.1 (31.6-64.3) mU I-1, p < 0.05). There was no difference in plasma prorenin concentration between patients without and with microalbuminuria and between patients without and with background retinopathy. Plasma renin concentration, both when supine and upright, was similar in control subjects, in patients without complications, and in patients with varying degrees of diabetic microangiopathy. Plasma aldosterone was suppressed in patients without complications in comparison to control subjects (74 (58-95) vs 167 (140-199) ng I-1, p < 0.001) and was also suppressed in patients with microvascular disease. Plasma potassium was significantly higher in patients than in control subjects (mean +\\/- standard deviation: 4.10 +\\/- 0.36 vs 3.89 +\\/- 0.26 mmol I-1; p < 0.001) and plasma sodium was significantly lower (138 +\\/- 4 vs 140 +\\/- 2 mmol I-1; p < 0.001). We conclude that plasma prorenin is not a useful early marker for diabetic microvascular disease. Despite apparently normal plasma renin concentrations, plasma aldosterone is suppressed in insulin-dependent diabetic patients.

    1987-08-01

    The width (Wr/Wo) and the intensity (Ir) of the central light reflex were studied on retinal arteries and veins in insulin-dependent diabetic patients. A diabetic group (n = 45) was compared to normal subjects (n = 57), and the groups were matched according to age and blood pressure levels. A computerized scanning microdensitometer was applied across various sites on vessels in fundus photographs. The Ir of the reflected light was significantly reduced in diabetic arteries and veins compared to the vessels in the control group (P less than 0.001). This may implicate abnormalities in blood rheology of the retinal circulation in diabetes. The Wr/Wo was found narrower in veins in diabetic patients (P less than 0.001). This probably indicates differences in haemodynamics of venous flow in diabetic and normal subjects. The intensity was correlated to the duration of diabetes (P less than 0.05), while neither the width nor the intensity were found related to sex, metabolic control, intraocular pressure or retinopathy.

    1985-03-01

    The glycaemic responses of 12 C-peptide negative insulin-dependent diabetics were studied following four breakfasts with different carbohydrate sources. Total energy content of the meals was the usual for each subject, carbohydrate supplying 55% and fat 32%. The meals comprised: wholemeal bread with margarine; white bread with margarine; marmalade made with sucrose, and cheddar cheese; and marmalade (22% of total energy) on wholemeal bread with margarine. The study demonstrated powerfully that there were no statistically significant or clinically relevant differences between the meals in post-prandial glucose peak elevation, or in incremental area under the blood glucose curve to 120 mins. On these grounds, sucrose, in amounts considered acceptable to the general population, need not be prohibited from diabetic diets.

    Full Text Available Background: Diabetes mellitus is the most common endocrine metabolic disorder of childhood and adolescence with important consequences for physical and emotional development. Aim of the study: This study was designed to detect the effect of diet therapy (through nutrition education program on lipid profile and blood glucose level in diabetic children. Subjects and Methods: The study was carried on 45 diabetic children aged between 8-15 years old at diabetic nutrition clinic of nutrition institute in Cairo from 2003-2005. Children included in the study were divided into two groups: insulin dependent dyslipidemic group (IDDM (diet control/ group and insulin dependent non dyslipidemic (control group. All were subjected to full dietetic history by the 24 hour recall for 3 days, thorough clinical examination, they were evaluated for plasma lipids, lipoproteins, fasting blood glucose (FBG and glycated hemoglobin (HbA1c levels. The dyslipidemic were measured after three months for the previously measured parameters. The nutrition education process was performed and continued on weekly intervals for three months. Results: There was significant decrease in serum cholesterol and triglyceride levels in the study group after the program, and insignificant increase in serum HDL and decrease in serum LDL. Also, there was insignificant decrease in FBG but there was statistically significant decrease in HbA1 after the program. These changes occurred in parallel with increases in intakes of protein and total calories with adequate carbohydrate and sometimes a reduction in intakes of total fat. Conclusion: Nutrition therapy for children with IDDM is essential to improve measures of glycemic control and lipoprotein mediated risk for dyslipidemia. More innovative approaches to achieve lifestyle changes are required to meet current recommendations which are likely to produce greater beneficial changes than those observed in this study

    2015-08-01

    Full Text Available AIM : The present study was done to evaluate the prevalence of hepatitis C virus (HCV infection in non - insulin dependent diabetic patients (NIDDM and to investigate influence of HCV seropositivity on several factors such as age of onset of diabetes, complicat ions and mode of treatment. METHODS: The study is prospective, hospital based case - control study done over a period of 3 years. A total of 428 diabetic patients were compared with 1800 voluntary blood donors for the presence of HCV infection. Serological testing for anti HCV was done by using commercial enzyme linked immunosorbent assay (ELISA. Data about various variables were collected from diabetic patients using a structured questionnaire after taking informed consent. RESULTS: Higher prevalence of H CV (7.71% infection rate observed in NIDDM patients in comparison with blood donors (1.1%. In our study, HCV seropositivity is highest (11.81% in 40 - 50 years age group followed by (8.57% 30 - 40 years age and least (2.43% in age > 61 years. Mean age of onset of diabetes mellitus (DM is 39 years in HCV +ve patients in comparison with 46 years in non - reactors. Proportion of seropositive cases among male and female diabetic cases did not show significant difference. Out of 33 HCV seropositive cases, 63.64% managed with insulin and 48.49% oral hypoglycemic drugs with insulin supplement. Ten out of 33 (30.30% HCV seropositive cases presented with one or more late diabetic complications compared to 78 out of 395 (19.75% seronegative cases, with diabetic neph ropathy being commonest one. CONCLUSION: Although, HCV infection is more common among adults with type 2 diabetes, it is uncertain whether HCV infection precedes the development of diabetes. Hence, there is a need to perform a prospective analysis to inves tigate, in persons who acquire type 2 diabetes whether they are more likely to have had antecedent HCV infection

    To assess the metabolic disturbances, and, in particular, the occurrence of high blood ketone body concentration in post-absorptive Type 2 (non-insulin-dependent) diabetic patients as compared to a matched normal population, a study was carried out in a group of 78 Type 2 diabetic outpatients matched for age and sex and in 78 normal individuals. In all subjects we measured HbA1c, and fasting levels of glucose, FFA, lactate, pyruvate, glycerol, alanine, 3-hydroxybutyrate, acetoacetate, uric acid, total cholesterol, triglycerides, creatinine, growth hormone, cortisol, glucagon, free insulin, and C-peptide. Multistix strips were used for urine ketone determination. As expected HbA1c, and plasma glucose were higher in Type 2 diabetics. This was associated with multiple metabolic disturbances as shown by higher circulating concentrations of FFA, glycerol and gluconeogenic precursors. Similarly, blood levels of ketones (351 +/- 29 vs 159 +/- 15 umol/l; P growth hormone. Plasma glucagon levels were higher in Type 2 diabetics. Blood ketone body levels were directly correlated with both plasma glucose and FFA concentrations. These observations clearly show that Type 2 diabetes is a pathologic condition characterised by multiple metabolic disturbances which are fully apparent in the basal state. Furthermore, we emphasise that Type 2 diabetic patients, though not insulin deficient, may present a significant increase in their fasting levels of ketone bodies.

    The international community of diabetologists is rapidly becomine involved in intervention trials aimed at preventing insulin-dependent diabetes in high risk relatives. Whereas age and relationship to a proband with insulin-dependent diabetes mellitus interacting with detected islet cell autoantibodies (ICA) are risk factors, their independent contribution to that risk remains unclear. In a prospective study of 6851 nondiabetic relatives of 2742 probands conducted between 1979-1993, we found age, but not relationship, to be a dramatic risk variable in ICA-positive persons as estimated by the Cox regression model. The 5-yr risk of insulin-dependent diabetes mellitus was 66% for those found to have ICA detectable before age 10 yr, falling progressively to less than 16% for ICA-positive relatives over age 40 yr. In ICA-negative relatives, age and relationship are independent prognostic variables. 15 refs., 4 figs., 2 tabs.

    Full Text Available The aim of this case-control study conducted in Belgrade during 1994-1997 was to investigate whether parental demographic characteristics and habits are associated with insulin-dependent diabetes mellitus (IDDM. Case group comprised 105 children up to 16 years old with IDDM and control group comprised 210 children with skin diseases. Cases and controls were individually matched by age (± one year, sex and place of residence (Belgrade. According to %l test results, children with IDDM significantly had five or more family members and they also significantly more frequently had poor socio-economic status than their controls. Higher education of fathers was significantly more frequently reported in diabetic children, in comparison with their controls. Parents of diabetic children were significantly more frequently occupationally exposed to radiation petroleum, and its derivates, organic solvents, dyes and lacquers. During pregnancy mothers of diabetic children significantly more frequently smoked cigarettes and consumed coffee, coca-cola, alcohol and foods containing nitrosamines. Fathers of diabetic children more frequently consumed alcohol.

    Non-insulin-dependent diabetes mellitus remains a major cause of morbidity and premature mortality in our community. Although potentially amenable to control by lifestyle modification, this is difficult to achieve in practice. Additional approaches using drugs that enhance insulin secretion, suppress hepatic glucose production, and increase insulin sensitivity are available, and new agents are being developed. The thiazolidinedione drugs hold particular promise as insulin-sensitizing agents; however, at present, insulin administration is often also required. The importance of detection and treatment of risk factors for cardiovascular disease and the earlier detection and management of microvascular and infective complications remain of crucial importance.

    Full Text Available Anxiety sensitivity is defined as a belief that anxiety or fear may cause illness, embarrassment, or additional anxiety. The main purpose of this study was to find out if there were differences among adolescents with insulin dependent diabetes mellitus, adolescents with somatoform autonomic dysfunction and their healthy peers in different aspects of psychological functioning and anxiety sensitivity. The sample consisted of 93 subjects, aged 12 to 16. Hamburg Neuroticism and Extraversion Scale, Child Behaviour Checklist and Childhood Anxiety Sensitivity Index were administrated. The adolescents with somatoform autonomic dysfunction had significantly higher scores on neuroticism scale, different Child Behaviour Checklist subscales, and on anxiety sensitivity. Both groups with diagnosed illness had lower scores on extraversion scale compared to healthy peers. This study has shown that the adolescents with somatoform autonomic dysfunction are more prone to fears regarding bodily functioning, and that they are at a higher risk of developing an anxiety disorder.

    Full Text Available Background and Objectives: The absence, destruction, or loss ofβ-cells of pancreas results in type 1 diabetes (insulin-dependent diabetes mellitus [IDDM]. Presently, diagnosis and periodic monitoring of diabetes is achieved by evaluating blood glucose levels as it is relatively invasive and dreaded by children. In the light of this, present study was planned to compare salivary glucose values with blood glucose values and the biochemical characteristics of saliva in IDDM children were evaluated and obtained results were compared with the salivary parameters of normal children. Materials and Methods: Thirty IDDM children and 30 healthy children were selected for the study. Fasting blood sample and unstimulated salivary sample were collected from all the subjects and were subjected for analysis. Results: A weak positive correlation was noticed between fasting blood glucose and salivary glucose values in IDDM children. But a mean average of salivary glucose was high in IDDM children when compared with healthy children. The biochemical parameters like acid phosphatase, total protein count, and α-amylase were increased, whereas salivary urea did not show significant variation between the groups.Conclusion: With presently used diagnostic armamentarium, estimation of salivary glucose cannot replace the standard method of estimation of glucose in diabetic mellitus children. The established relationship was very weak with many variations.

    Serum fructosamine activity was studied in 42 patients with type I (insulin dependent) diabetes mellitus and 30 non-diabetic volunteers as an index of blood glucose control. There was a significant correlation both between fructosamine and glycosylated haemoglobin values (r = 0.82) and between fructosamine and the fasting C peptide concentration (r = -0.81). Test results in 14 of the diabetics reflected the mean plasma glucose concentration calculated from 25 serial estimations in a single 24 hour period (r = 0.75; p less than 0.01) but not the mean amplitude of glycaemic excursion (r = 0.23; p greater than 0.05). Fructosamine concentrations measured in these multiple blood specimens did not change significantly throughout the day (mean coefficient of variation 4.1%) despite wide variability of the respective plasma glucose concentrations (mean coefficient of variation 36.2%). It is concluded that a single random serum sample analysed for fructosamine concentration provides a simple and reliable assessment of glucose homoeostasis in patients with type I diabetes mellitus.

    To evaluate the glomerulo-tubular balance of sodium and water in the proximal tubules of diabetic patients with elevated glomerular filtration rate, the renal plasma clearance of lithium and the glomerular filtration rate (51Cr-EDTA plasma clearance) were determined simultaneously in 11 ambulatory Type 1 (insulin-dependent) diabetic patients (aged 25-35 years) with no evidence of diabetic nephropathy and in 10 age-matched healthy subjects. The renal plasma clearance of lithium, which is a measure of flow from the proximal tubule into the thin descending limb of the loop of Henle, did not differ between diabetic and control subjects (28.9 +/- 4.0 versus 28.3 +/- 5.1 ml/min per 1.73 m2 surface area, mean +/- SD), whereas the glomerular filtration rate in the diabetic patients was significantly higher than in the control subjects (136 +/- 10.2 versus 108 +/- 13.6 ml/min per 1.73 m2, p less than 0.001). The same held true for the fractional reabsorption rate in the proximal tubules (78.7 +/- 3.2 versus 73.6 +/- 4.9%, p less than 0.02). The results indicate that the elevation of the glomerular filtration rate in diabetic patients is associated with a parallel increase in the proximal reabsorption rate. This type of glomerulo-tubular balance implies that the flow of water and flux of sodium to the segments distal to the proximal tubule are kept constant during variations in the glomerular filtration rate.

  14. The carotid body of the spontaneous insulin-dependent diabetic rat

    Full Text Available The carotid bodies from adult spontaneous insulin-dependent diabetic rats (strain BB/S were perfusion-fixed at normal arterial blood pressure with 3% phosphate-buffered glutaraldehyde and compared with the organs from control rats (strain BB/Sc prepared in the same way. Serial 5-µm sections were cut, stained, and using an interactive image analysis system, were analysed to determine the volumes of the carotid body and its vascular and extravascular compartments. There was no evidence of systemic arterial disease in the carotid stem arteries in either group of animals, and the microvasculature of the organs appeared normal by light microscopy. The volume of the carotid body was unchanged 3 months after the onset of diabetes but was increased at 6 months. The total vascular volume of the organ was unchanged, but the volume of the small vessels (5-12 µm was increased. In the control group the small vessels comprised 5% of the total volume of the carotid body, or about 44% of the vascular compartment. The percentage of small vessels increased at 3 months in the diabetic group, but had returned to normal at 6 months. The extravascular volume followed the same pattern as the total carotid body volume and so did not change appreciably when expressed as a percentage of the total volume of the organ. The increase in size of the carotid body in diabetic rats is due, therefore, to an augmented extravascular volume. In one diabetic specimen the carotid sinus nerve showed signs of diabetic neuropathy, axonal swelling and intramyelinic oedema. The clinical implications of these results are discussed.

    PURPOSE: Microalbuminuria predicts early mortality in non-insulin-dependent-diabetes mellitus patients (NIDDM). Our objective in the present study was to compare and assess the relationship between 24-hour, day and nocturnal ambulatory blood pressure (BP) and urinary albumin excretion rate (UAE) in microalbuminuric and normoalbuminuric NIDDM and in normal control subjects. PATIENTS AND METHODS: In the present cross-sectional study, 24 hour ambulatory BP (daytime BP and nocturnal BP) and HbA1c were compared in microalbuminuric (n = 10) and nonmicroalbuminuric NIDDM patients (n = 10) and in nondiabetic controls (n = 9). None of the patients were taking antihypertensive agents. RESULTS: In the microlbuminuric group, whereas 24 hour and daytime systolic BP differed significantly from control values (P < 0.025 and P < 0.05 respectively), there was no difference between diabetic groups. However, nocturnal systolic BP in the microalbuminuric group was significantly higher than in the normoalbuminuric diabetic patients (139 vs. 125) (P < 0.05) and a significant difference was also found between the NIDDM patients and the control group (139, 125 vs. 114) (P < 0.025). In multiple regression analysis, only nocturnal systolic BP showed a significant relationship with UAE (P < 0.05). CONCLUSIONS: We suggest that the higher nocturnal systolic blood pressure seen in our microalbuminuric NIDDM patients may contribute to the increased morbidity in this group.

    The underlying causes of type 2 diabetes (T2DM) remain poorly understood. Adipose tissue dysfunction with high leptin, inflammation, and increased oxidative stress may play a pivotal role in T2DM development in obese patients. Little is known about the changes in the adipose tissue after Roux-Y gastric bypass (RYGB) in non-severely obese patients (BMI adipose tissue function in a cohort of BMI insulin-dependent T2DM after RYGB surgery which resolves T2DM. Twenty patients with insulin-dependent T2DM and BMI Insulin-resistance, leptin, oxidative stress, and cytokines were determined over 24 months. Expression of cytokines and NF-kappaB pathway genes were measured in leukocytes (PBMC). Adipose tissue inflammation was examined histologically preoperatively and 24 months after RGYB in subcutaneous adipose tissue. Insulin-resistance, leptin, oxidative stress as well as adipose tissue inflammation decreased significantly after RYGB. Similarly, systemic inflammation was reduced and peripheral blood mononuclear cells (PBMCs) were reprogrammed towards an M2-type inflammation. Loss of BMI correlated with leptin levels (r = 0.891, p insulin resistance (r = 0.527, p = 0.003), and oxidative stress (r = 0.592, p = 0.016). Leptin correlated with improved insulin resistance (r = 0.449, p = 0.032) while reduced leptin showed a strong association with improved oxidative stress (r = 0.809, p = 0.001). Lastly, reduced oxidative stress correlated strongly with improved insulin-resistance (r = 0.776, p = 0.001). RYGB improves adipose tissue function and inflammation. Leptin as marker for adipose tissue dysfunction may be the mediating factor between insulin resistance and oxidative stress and thereby likely improving T2DM.

    (1) Autonomic dysfunction is a well recognised complication of diabetes mellitus and early detection may allow therapeutic manoeuvres to reduce the associated mortality and morbidity. We sought to identify early cardiovascular autonomic neuropathy using spectral analysis of heart rate and systolic blood pressure variability. (2) Thirty patients with Type 1 (insulin-dependent) diabetes mellitus (DM) and 30 matched control subjects were studied. In addition to standard tests of autonomic function, heart rate and systolic blood pressure variability were assessed using power spectral analysis. From the frequency domain analysis of systolic blood pressure and R-R interval, the overall gain of baroreflex mechanisms was assessed. (3) Standard tests of autonomic function were normal in both groups. Total spectral power of R-R interval was reduced in the Type 1 DM group for low-frequency (473 +/- 63 vs. 747 +/- 78 ms2, mean +/- S.E.M., P = 0.002) and high-frequency bands (125 +/- 13 vs. 459+/-90 ms2, P standing (2.9+/-0.9 vs. 7.18+/-1.9 ms/mmHg, P < 0.001). (4) Spectral analysis of cardiovascular variability detects autonomic dysfunction more frequently in Type 1 DM patients than conventional tests, and is suggestive of an abnormality of parasympathetic function. The abnormality of baroreceptor-cardiac reflex sensitivity could be explained by this impairment of parasympathetic function and this may predispose to the development of hypertension and increase the risk of sudden cardiac death. Using spectral analysis methods may allow detection of early diabetic cardiac autonomic neuropathy and allow therapeutic intervention to slow the progression.

    A deceased 59-year-old woman with insulin dependent diabetes mellitus complicated by chronic thyroiditis and chronic hepatitis was autopsied. She had had diabetes mellitus since she was 30 years old, and insulin therapy was started at 34 years. Laboratory findings were as follows: s-GOT 85, s-GPT 31, gamma-globulin 2.45 g/dl. Immunological tests were positive for anti-smooth muscle antibody and anti-ENA antibody with high titers of antithyroglobulin and anti-microsome antibodies. HLA analysis revealed the presence of DR-4. The thyroid biopsy specimen showed microscopic features characteristic of chronic thyroiditis at 52 years of age. She had been repeatedly admitted for the control of diabetes mellitus. She was admitted for the 9th time in June, 1987 following complaints of abdominal pain. After admission, her general condition became gradually worse, and she died of peritonitis in September, 1987. Pathological examination of the liver revealed an expansion of fibrous tissue on Glisson's capsule accompanied by lymphocytic infiltration and was diagnosed to be chronic inactive hepatitis. As for the thyroid gland, fibrous tissue replaced an extensive area of the thyroid gland, and normal thyroid tissue was not observed. Lymphocytic infiltration was less in comparison with that in the previous biopsy. As for the pancreas, atrophy of exocrine pancreatic tissue and fibrous change in interstitial tissue was observed. Lymphocytic infiltration was also seen in the interstitial exocrine tissue but not in the islet. Immunohistochemical examination of the islets using anti-insulin, glucagon and somatostatin antibodies by ABC peroxidase method showed the selective disappearance of B cells in the islets. The pathological changes in the thyroid gland, liver and pancreas suggest that autoimmune mechanism may be involved in the pathogenesis of chronic thyroiditis, chronic hepatitis and IDDM with exocrine pancreatic impairment in this case.

  8. The cost of insulin-dependent diabetes mellitus (IDDM) in England and Wales.

    Science.gov (United States)

    Gray, A; Fenn, P; McGuire, A

    1995-12-01

    This study estimates the direct health and social care costs of insulin-dependent diabetes mellitus (IDDM) in England and Wales in 1992 to be 96 million pounds, or 1021 pounds per person in a population with IDDM estimated at 94,000 individuals. These costs include insulin maintenance, hospitalization, GP and out-patient consultations, renal replacement therapy, and payments to informal carers. Expenditure is concentrated on younger age groups, with one-third of the total expended on those aged 0-24. Around one-half of the total costs can be directly attributed to IDDM, with the remainder associated with a range of complications of the disease. The single largest area of service expenditure is renal replacement therapy. The cost estimates are most sensitive to incidence rates of IDDM, numbers on dialysis and average duration of dialysis. A further 113 million pounds may be lost each year due to premature deaths resulting in lost productive contributions to the economy. The direct and indirect costs of IDDM are therefore significant. The cost of illness framework presented here should facilitate the economic evaluation of new and existing treatment regimens, which may improve value for money by reducing costs and/or increasing the quality or quantity of life for people with IDDM.

The coefficients of variation of the corresponding plasma insulin values were 19.2, 24.8, and 34.8%, respectively. The coefficient of variation of 24-h...... urinary C-peptide excretion was 22.1%. Because fasting plasma C-peptide correlated closely with plasma C-peptide 6 min after glucagon (test 1: r = .70, P less than .01; test 2: r = .76, P less than .01), it seems that these two values can be used equally well as assessment of beta-cell function in NIDDM...

    Latvian insulin-dependent diabetes mellitus (IDDM) patients (n=101) and healthy controls (n=111) were analyzed for HLA-DR and DQ polymorphism. DR3-DQ2 and DR4-DQ8 were positively associated and DR15-DQ6, DR13-DQ6, DR1-DQ5 and DQ7 negatively associated with the disease. The incidence of IDDM in Latvia is very low (6.5 per 100,000) compared to Sweden (24.4 per 100,000), even though Latvia is close to Sweden. The reasons for the decreased incidence are not clear. When the negatively associated DQ were taken together in the healthy controls, more than 75% of the healthy controls were positive for one of the four negatively associated DQ molecules. The excess frequency of the negatively associated DQ molecules in the general population could explain the lower incidence of IDDM in Latvia. Association of HLA-DR and DQ genes with autoantibody markers shows DR3, but not DQ2, to be increased in GAD65 antibody-positive compared to antibody-negative patients. This association was not observed with ICA512 antibodies.

    Mice deficient in hepatocyte nuclear factor 1 alpha (HNF-1α) were produced by use of the Cre-loxP recombination system. HNF-1α-null mice are viable but sterile and exhibit a phenotype reminiscent of both Laron-type dwarfism and non-insulin-dependent diabetes mellitus (NIDDM). In contrast to an earlier HNF-1α-null mouse line that had been produced by use of standard gene disruption methodology (M. Pontoglio, J. Barra, M. Hadchouel, A. Doyen, C. Kress, J. P. Bach, C. Babinet, and M. Yaniv, Cell 84:575–585, 1996), these mice exhibited no increased mortality and only minimal renal dysfunction during the first 6 months of development. Both dwarfism and NIDDM are most likely due to the loss of expression of insulin-like growth factor I (IGF-I) and lower levels of insulin, resulting in stunted growth and elevated serum glucose levels, respectively. These results confirm the functional significance of the HNF-1α regulatory elements that had previously been shown to reside in the promoter regions of both the IGF-I and the insulin genes.

    Several genomic polymorphisms at the insulin (INS) gene and its flanking regions were analyzed in 197 unrelated Caucasian patients affected by insulin-dependent diabetes (IDDM) and 159 ethnically matched, normal controls ascertained from the South-Eastern United States. We found that the frequency of homozygotes for the common variant at the insulin gene was significantly increased in the diabetic population (RR = 2.0, p INS gene. We determined the HLA-DQB1 genotypes by denaturing gradient gel electrophoresis (DGGE) and/or sequence-specific primers (SSP) techniques to assess the possible interactions between INS and HLA. DQB1*0302 had the strongest predisposing effect on IDDM susceptibility (RR = 9.3) and DQB1*0602 the strongest protective effect (RR = 0.02). However, a significant predisposing effect of DQB1*0201 could be demonstrated only after removal of the effects of DQB1*0302 and DQB1*0602. Analyses of the genotypes revealed that all genotypes containing 0602 were protective and that the heterozygous genotype 0201/0302 and homozygous genotype 0302/0302 confer the highest risk (RR = 20.9 and 12.9 respectively). However, heterozygous genotypes 0302/X (X excludes 0201, 0302 and 0602) have a significantly lower predisposing risk. Similarly, there is heterogeneity in risk between predisposing 0201/0201 homozygous individuals and protective 0201/X individuals. When subjects were stratified by HLA genotypes, the relative risks conferred by INS did not vary, thus suggesting that the susceptibility effects conferred by HLA and INS are additive rather than interactive.

    Dodecanedioic acid (C12) is an even-numbered dicarboxylic acid (DA). Dicarboxylic acids are water-soluble substances with a metabolic pathway intermediate to those of lipids and carbohydrates. Previous studies showed that contrary to other DAs, very low amounts of C12 are lost with urine. The effects of 46.6 mmol of C12 intravenous infusion for 195 min on blood glucose levels were investigated in five patients with non-insulin-dependent diabetes mellitus (NIDDM), with a good metabolic compensation, and in five healthy volunteers matched for gender, age, and body mass index. Blood samples were taken every 15 min for a period of 360 min to measure glucose, insulin, C-peptide, ketone bodies, and free fatty acid (FFA) levels, and 24-h urine samples were collected to measure C12 and urea excretion. Plasma and urinary C12 concentrations were determined by high-pressure liquid chromatography (HPLC). Indirect calorimetry was continuously performed both basally and during the study period. The average 24-h urinary excretion of C12 was 6.5% versus 6.7% of the administered dose, respectively, in NIDDM patients and in healthy controls. The area under the curve (AUC) values of plasma C12 were 279.9 +/- 42.7 mumol in NIDDM patients and 219.7 +/- 14.0 mumol in controls (P = ns). Plasma glucose levels significantly decreased in NIDDM patients during C12 infusion (from 7.8 +/- 0.6 to 5.4 +/- 0.8 mM at the end of the study period, P acids decreased in diabetic patients from the beginning until the end of C12 infusion, although this difference did not reach statistical significance. No significant increase was found between basal and final values in VO2 consumption and in the values of nonprotein respiratory quotient in both groups of subjects examined. The experimental data indicate that C12 infusion decreases plasma glucose levels in NIDDM patients to normal range without influencing plasma insulin levels. The balance between pyruvate and lactate was affected by C12 infusion only

    The acute effects of iv somatostatin (SRIH; 100 micrograms/h) on the urinary flow (Uvol), effective renal plasma flow (RPF), and glomerular filtration rate (GFR) were compared with those of a control infusion of 0.15 M NaCl in nine insulin-dependent diabetic (IDD) patients of less than 10 yr disease duration and six normal subjects (NS). RPF and GFR were measured using a standard primed constant isotope infusion of (/sup 125/I)iodohippurate and (51Cr)chromium EDTA. Uvol, RPF, and GFR were measured during 20-min clearance periods. During the NaCl infusion mean Uvol, RPF, and GFR were 14.1 +/- 0.2 (+/- SEM), 708 +/- 4, and 150 +/- 1 mL/min in the IDD group and 12.7 +/- 0.4, 568 +/- 5, and 110 +/- 2 mL/min in the NS group, respectively. In the IDD patients Uvol, RPF, and GFR decreased from 16.6 +/- 1.8, 670 +/- 30, 146 +/- 4 mL/min pre-SRIH to 9.2 +/- 1, 553 +/- 25 (P less than 0.001), and 130 +/- 5 mL/min, respectively, at 120 min during the SRIH infusion. Similarly, in the NS group mean Uvol, RPF, and GFR were 14.2 +/- 0.6, 552 +/- 15, and 112 +/- 5 mL/min pre-SRIH and decreased to 7.4 +/- 0.6, 422 +/- 7, and 93 +/- 3 mL/min, respectively, after 120 min of the SRIH infusion. SRIH, therefore, had a profound effect on renal function in both IDD patients and NS, resulting in a reduction in RPF, GFR, and, as a consequence, Uvol.

    A population association has consistently been observed between insulin-dependent diabetes mellitus (IDDM) and the class 1 alleles of the region of tandem-repeat DNA (5[prime] flanking polymorphism [5[prime]FP])adjacent to the insulin gene on chromosome 11p. This finding suggests that the insulin gene region contains a gene or genes contributing to IDDM susceptibility. However, several studies that have sought to show linkage with IDDM by testing for cosegregation in affected sib pairs have failed to find evidence for linkage. As means for identifying genes for complex diseases, both the association and the affected-sib-pairs approaches have limitations. It is well known that population association between a disease and a genetic marker can arise as an artifact of population structure, even in the absence of linkage. On the other hand, linkage studies with modest numbers of affected sib pairs may fail to detect linkage, especially if there is linkage heterogeneity. The authors consider an alternative method to test for linkage with a genetic marker when population association has been found. Using data from families with at least one affected child, they evaluate the transmission of the associated marker allele from a heterozygous parent to an affected offspring. This approach has been used by several investigators, but the statistical properties of the method as a test for linkage have not been investigated. In the present paper they describe the statistical basis for this transmission test for linkage disequilibrium (transmission/disequilibrium test [TDT]). They then show the relationship of this test to tests of cosegregation that are based on the proportion of haplotypes or genes identical by descent in affected sibs. The TDT provides strong evidence for linkage between the 5[prime]FP and susceptibility to IDDM. 27 refs., 6 tabs.

    Intra-abdominal liver biopsies were obtained during surgery from fasted obese patients with non-insulin-dependent diabetes mellitus (NIDDM), obese normoglycemic controls, and lean controls. Lipid synthesis was studied in freshly isolated hepatocytes and liver homogenates from the three groups of subjects. Incorporation of 3H2O into the lipids of hepatocytes was determined in the absence and presence of insulin (0.1 mumol/L). The activities of five enzymes involved in fatty acid synthesis, and the incorporation of 14C-glycerol-3-phosphate into lipids were determined in liver homogenates. Basal lipid synthesis by hepatocytes was not different in the three groups of patients. Insulin stimulated lipogenesis by 8% +/- 30% in the lean controls, 33% +/- 8% in the obese controls and 17% +/- 6% in the NIDDM patients. No significant differences in the activities of the five enzymes that are involved in de novo fatty acid synthesis among the three groups of patients were observed. Similarly, incorporation of 14C-glycerol-3-phosphate by liver homogenates, in the presence of saturating or submaximal concentrations of fatty acids, did not differ among the three groups. These results show that under the experimental conditions of this study, including the fasted state of the patients, the basal capacity of liver of NIDDM patients to synthesize fatty acids or glycerides is the same as that of liver from obese and lean controls. Thus, it is likely that an increase in fatty acid flux into a liver with normal lipogenic potential may contribute to the increased synthesis of triglycerides by the liver of these patients in vivo.

    Retinal status and glycosylated hemoglobin (GHb) was followed in 32 patients with insulin-dependent diabetes mellitus (18 females; age upon entering the study 26 +/- 8 years; duration of diabetes 10 +/- 6 years; means +/- SD) during a total of 136 patient-years, i.e. during 4.3 +/- 0.6 years per patient. Annual mean GHb (given in percent of the mean normal GHb) was calculated from 7 +/- 3 determinations of GHb per patient-year. Fluorescein angiographs were performed at least once per patient-year, and retinal status was assessed by counting microaneurysms. Upon entering the study, early diabetic (background) retinopathy was present in 14 patients; at the end of the follow-up period, it was present in 20 patients. Retinal status deteriorated in 4/42 patient-years with excellent metabolic control (annual mean GHb less than or equal to 125%), in 13/70 patient-years with good control (annual mean GHb 126-150%) and in 8/24 patient-years with poor control (annual mean GHb greater than 150%). The incidence rate of retinal deterioration differed significantly between years with excellent control and years with poor control (X2 5.7, df = 1, p less than 0.05). It is concluded that excellent metabolic control within 14 +/- 6 years after onset of insulin-dependent diabetes mellitus appears to be a protective factor against the development or progression of early diabetic retinopathy.

    Full Text Available Background: Self-efficacy is a crucial factor in controlling adolescents with insulin-dependent diabetes mellitus (IDDM. Subsequently the negative behavioral reactions such as aggression adversely affect on self-efficacy. Therefore, interventions are essential to reduce the aggression and to improve the self- efficacy in these patients. Aim: To determine the efficacy of the modified "aggression replacement training" program on self-efficacy of adolescents with insulin-dependent diabetes. Methods: In this clinical trial, 70 adult subjects with IDDM who were referred to Parsian Diabetes clinic of Mashhad in 2014 were divided into two groups of intervention and control. The intervention program, including three aspects including: anger control training, social skills training and moral reasoning training was performed in five sessions, each 1.5-2 hours. A five-day interval was between the sessions and each group consisted of 8-10 individuals. The self-management standard questionnaire of “insulin-dependent diabetes management self-efficacy scale (IDMSE” was filled before the intervention and two months afterwards. Data were analyzed using SPSS version 11.5 with paired and Independent t-tests. Results: In this study, 38.5 and 61.5 percent of the subjects were boys and girls, respectively with total mean age of 15.9±2. The self-efficacy of the subjects before the intervention was not significantly different within the groups (p=0/57. Nevertheless in post-intervention assessment, the self-efficacy of the Intervention group significantly increased (49.0±11.1 compared to the control group (33.7±5.5 (p

    The serum fructosamine concentration was examined as a new means to monitor metabolic control in non-insulin-dependent diabetes during changes in management. Weekly fructosamine estimations were compared with glycosylated haemoglobin (HbA1c), 24 hour urinary glucose, and fasting plasma glucose concentrations in a 17 week study entailing withdrawal and reinstitution of oral treatment. The serum fructosamine concentration was more sensitive than the other measurements in detecting a deterioration in diabetic control after stopping oral hypoglycaemic drugs. The response to reinstitution of treatment was not significant in the first three weeks (p = 0.266), despite a highly significant reduction in fasting plasma glucose (p = 0.001) and 24 hour urinary glucose concentrations (p = 0.012). Compared with HbA1c, concentrations of fructosamine appeared more useful in monitoring short term (three to six weeks) changes after alterations in management of diabetes. Additional advantages were lower cost and technical simplicity of measurement. PMID:6426612

    To study the efficacy and safety of the Jiang Tang Fang Long Jiao Nang (Hypoglycemic Anti-Deafness Capsule) in treating non-insulin dependent diabetes mellitus with hearing loss. Methods Two hundred ninety six patients with non-insulin dependent diabetes mellitus and hearing loss were randomly assigned to a treatment group(n=164, 208 ears) and a control group(n=132,184 ears). Patients in the treatment group were treated with the Jiang Tang Fang Long Jiao Nang and supplement herbal preparations as indicated by traditional Chinese medicine dialectical assessment, while control patients received glibenclamide and conventional treatments for deafness. Hearing, fasting blood glucose (FBG), post-prandial blood glucose(PBG), 24 hour urine sugar, platelet function indices, blood superoxide dismutase (SOD) and lipid peroxides (LPO) levels, and symptom improvement were compared between the two groups. Results The rate of hearing improvement was 56.7% for the treatment group and 26.6% for the control. FBG, PBG and 24 hour urine sugar improved in both groups, but the last two were superior in the treatment group compared to the control. Symptoms improvement was also superior in the treatment group compared to the control. In patients receiving Jiang Tang Fang Long Jiao Nang treatment, platelet function indices, SOD and LPO were all improved, while only LOP improvement was noticed in control patients. No acute or long-term toxicity was demonstrated for the Jiang Tang Fang Long Jiao Nang in animal tests. The Jiang Tang Fang Long Jiao Nang lowered blood glucose and serum triglycerides in a rat model of alloxan-induced diabetes. Conclusion The Jiang Tang Fang Long Jiao Nang is effective in improving hearing and diabetic indices in diabetic patients with deafness, without significant side effects.

    In this study, we review the efficacy and safety limitations of insulin-dependent oral antidiabetic agents. In terms of efficiency, the main drawback of metformin, sulfonylureas, gliptins and -to a lesser extent-glitazones is durability. No drug per se is able to maintain stable blood glucose control for years. Metformin, sulfonylureas and gliptins have demonstrated safety. Experience with the first two drug groups is more extensive. The main adverse effect of metformin is gastrointestinal discomfort. Major concerns related to the use of sulfonylureas are hypoglycemia and weight gain. The use of pioglitazone has been associated with an increased risk of bladder cancer, edema, heart failure, weight gain, and distal bone fractures in postmenopausal women. The most common adverse reactions associated with glucagon-like peptide-1 agonists are gastrointestinal discomfort that sometimes leads to treatment discontinuation.

    In a planned 5-year study, 97 patients with insulin dependent diabetes mellitus (IDDM), non-proliferative retinopathy and unsatisfactory blood glucose control were monitored for 3 years. The patients were randomized to an intensified conventional treatment (ICT, n = 44) or a regular treatment (RT, n = 53) group. HbA1c (normal range 3.9-5.7%) was reduced from 9.5 +/- 0.2 (mean value +/- SEM) to 7.4 +/- 0.1% in the ICT group (P = 0.0001), and from 9.5 +/- 0.2 to 9.0 +/- 0.2% in the RT group (P = 0.004). Nerve conduction velocities in the sural and peroneal nerves (P = 0.01-0.0001) were impaired in the RT group, but not in the ICT group. Retinopathy increased in both groups. The condition of 22 ICT patients (50%, 95% confidence interval 34-66%) and 37 RT patients (73%, 61-84%) deteriorated with regard to at least one microvascular complication (retinopathy, nephropathy, neuropathy) (P = 0.024). Lower HbA1c levels during the study significantly reduced the risk of deterioration (P = 0.01). In total, 57% of the ICT patients had at least one episode of serious hypoglycaemia, compared with 23% in the RT group (P = 0.001). The patients in the ICT group also gained weight (P = 0.0001). Improved blood glucose control slowed down the progression of microangiopathy during a 3-year period in patients with non-proliferative retinopathy, but at the price of an increased frequency of serious hypoglycaemic episodes, and some gain in body weight.

    Minimal vascular resistance (MVR) was determined in a paralysed cutaneous vascular bed at the dorsum of the foot in diabetic patients. Twelve long-term insulin-dependent diabetic (IDDM) patients with and nine short-term IDDM patients without nephropathy and retinopathy and eight control subjects......-wise increases of external counter pressure. The MVR was calculated from the reciprocal of the slope of the relationship between blood flow and applied pressure. The MVR was significantly increased in diabetic patients with (mean: 9.3 mmHg ml-1.100 g.min) and without nephropathy and retinopathy (8.5 mmHg ml-1.......100 g.min) compared with non-diabetic subjects (5.2 mmHg ml-1.100 g.min) (p less than 0.001 and p less than 0.005, respectively). Diabetic microangiopathy (increased hyalinosis of the basement membranes in the terminal arterioles) was found in skin biopsies in nine of the 12 long-term IDDM patients...

    The Diabetes Control and Complications Trial has shown that intensive treatment can deter the development and progression of diabetic complications. Integral to intensive treatment is improved glycemic control. To describe the trend in glycemic control for subjects with insulin-dependent diabetes mellitus, we examined the medical records of 662 subjects seen between 1978 and 1989 at the Model Demonstration Unit of the Diabetes Research and Training Center (Washington University School of Medicine). Mean value of glycated hemoglobin showed steady decline from a peak of 11.5% in 1979 to 9.0% in 1989. This decline was observed both in subjects evaluated only once (annual rate of decline estimated from linear regression, -0.17 +/1 0.03; p = 0.0001) and in subjects evaluated more than once (annual rate of decline estimated from growth curves, -0.18 +/- 0.06; p = 0.0001). These results suggest that substantial lowering of glycated hemoglobin has occurred during the last decade. This reduction should result in a lowered risk of diabetic complications.

    Full Text Available Background: Diabetes mellitus (DM is a common metabolic disorder that can cause various complications including, peripheral neuropathy (PNP. Some possible risk-factors such as blood glucose level, hyperglycemia, duration of diabetes, and lipid profiles are assumed to be important in diabetic PNP incidence. The aim of this study is to evaluate the prevalence and possible risk-factors of PNP in children with insulin dependent DM. Materials and Methods: Among diabetic children, 146 patients (up to 18-years old were evaluated in this cross-sectional study. All patients were examined for signs and symptoms of neuropathy and nerve conduction studies were performed. Blood level of glucose and lipid profiles were also tested. The relation between variables was compared by independent t-test and logistic regression test. Results: The mean age of diabetic children was 11.9 ± 3.3 years whereas mean diabetes duration was 3.8 ± 2.9 years. PNP was detected in 40 patients (27.4% that 62.5% of them have subclinical and 37.5% have clinical neuropathy. According to logistic regression analysis, duration of diabetes was the most important factor in prevalence of PNP (5.7 ± 3.5 and 3.1 ± 2.5 years in patients with and without neuropathy respectively, P < 0.001, 95% confidence interval [1.15-1.54]. Conclusion: As most of the patients had subclinical PN, neurological assessment is recommended to detect subclinical neuropathy in asymptomatic type 1 diabetic children and it seems that the best way to prevent this complication is still rigid blood glucose control and periodic evaluations.

    The fractional plasma escape rates of glycated and non-glycated albumin have earlier been measured in groups of Type 1 (insulin-dependent) diabetic patients and control subjects. The escape of non-glycated albumin was similar in control subjects and normoalbuminuric patients, but elevated...... in patients with micro or macroalbuminuria. In all groups the escape rate of glycated albumin was lower than that of non-glycated albumin. Glycation increases the anionic charge of albumin. To assay for charge-dependent alterations of transport a selectivity index (non-glycated albumin/glycated albumin...... transport ratio) was determined from the disappearance data. The index was high in control subjects (1.021 +/- 0.0057 (SEM)). This reflects a mean difference between the two escape rates of 2.1% per hour (for comparison the mean of the fractional escape rate of non-glycated albumin of the normal control...

    The abundance of GLUT-4 protein in both total crude membrane and plasma membrane fractions of vastus lateralis muscle from 13 obese non-insulin-dependent diabetes mellitus (NIDDM) patients and 14 healthy subjects were examined in the fasting state and after supraphysiological hyperinsulinemia....... In the basal state the immunoreactive mass of GLUT-4 protein both in the crude membrane preparation and in the plasma membrane fraction was similar in NIDDM patients and control subjects. Moreover, in vivo insulin exposure neither for 30 min nor for 4 h had any impact on the content of GLUT-4 protein in plasma...... membranes. With the use of the same methodology, antibody, and achieving the same degree of plasma membrane purification and recovery, we found, however, that intraperitoneal administration of insulin to 7-wk-old rats within 30 min increased the content of GLUT-4 protein more than twofold (P

    The present study was undertaken to clarify the progression of urinary albumin excretion rate (UAER) in non-insulin-dependent diabetic (NIDD) patients 6 years after diagnosis, and to elucidate the risk factors of nephropathy. This is a population-based controlled (baseline) cohort study. The prospective evaluation utilized the diabetic patients as internal controls. The setting was an urban primary health care centre. Main outcome measures were the UAER-24 h and fractional urinary albumin excretion rate (FAC) and their relation to mean blood pressure, haemoglobin Alc, fasting serum insulin and cholesterol and renal size. UAER (mg/24 h) was increased (geometric mean, quartile 1 and 3) in the diabetic patients at baseline, compared to the non-diabetic control subjects; 21 (10 and 33) versus 12 (8 and 15), P = 0.0001 (Wilcoxon's rank test). The UAER-24 h was not increased in diabetic subjects at follow-up; 24 (7 and 49) P = 0.3791 versus diabetic subjects at baseline. Eighteen per cent of normoalbuminuric (UAER 300 mg/24 h). Of the microalbuminuric subjects 19% progressed to clinical nephropathy, 46% remained microalbuminuric and 35% remitted to normoalbuminuria. Serum insulin concentration, after assessment of confounding factors, measured at the baseline predicted the UAER for all diabetic subjects at follow-up in multiple linear regression analysis in an independent and significant way (P = 0.01). Serum insulin concentration (P = 0.034) and diuretic therapy (P = 0.050) at baseline independently predicted the outcome of the categorical variable progressor/nonprogressor (n = 22/86) based on the UAER-24 h at baseline and at follow-up. Progression of the UAER during the first 6 years is found among approximately every fifth NIDD subject who develops either microalbuminuria (from normoalbuminuria) or clinical nephropathy (from microalbuminuria). The role of serum insulin (insulin resistance) or some factor associated with it, is suggestive in the genesis of kidney

    The oral ethanol loading test (0.5 g per kg b.m. given as 40% solution) was carried out in 5 groups, each of 10 patients with non-insulin-dependent (type 2) diabetes before and after 10 days of treatment with one of the following sulphonylurea derivatives: tolbutamide 0.5 t.i.d., chlorpropamide 0.5 once daily morning, glibornuride 0.025 t.i.d, glibenclamide 0.005 t.i.d. and glipizide 0.005 t.i.d. The response to alcohol (facial flush, heart rate, blood pressure) were compared, and blood concentration of ethanol, acetaldehyde, pyruvate, lactate, carbonates as well as blood pH, pO2 and pCO2 were determined in fasting state and during 6 hours after alcohol ingestion. In all patients the family history of diabetes and the presence and degree of vascular complications were registered. Evident flushing phenomenon was observed in 6 patients treated with chlorpropamide, in 3 treated with tolbutamide, in 2 treated with glibenclamide, in one receiving glibornuride and in none treated with glipizide. All drugs caused a greater rise of blood ethanol and acetaldehyde levels in relation to the control tests, but the difference reached statistical significance only in the group receiving chlorpropamide. Moreover, patients (pooled) with positive thermographic response had also significantly higher blood levels of ethanol and acetaldehyde during the second test. The ratio of acetaldehyde to ethanol concentration in blood (mumol:mmol) was not significantly changed in any group indicating parallel impairment of both steps of ethanol metabolism. All studied drugs intensified to a similar degree the alcohol-induced hypoglycaemia, but had no significant effect on the decrease of blood pyruvate level neither on the increase of blood lactate level. They didn't change the post-alcohol decrease of blood bicarbonate and pH, and didn't modify the behaviour of partial gas pressure. There was also no difference between pooled groups of patients with positive and negative thermographic reaction

    Full Text Available Background. This study aimed to assess the relationship between diabetes, obesity, and hepatic steatosis in patients undergoing liver resection and to determine if these factors are independent predictors of major complications. Materials and Methods. Analysis of a prospectively maintained database of patients undergoing liver resection between 2005 and 2012 was undertaken. Background liver was assessed for steatosis and classified as <33% and ≥33%. Major complications were defined as Grade III–V complications using the Dindo-Clavien classification. Results. 504 patients underwent liver resection, of whom 56 had diabetes and 61 had steatosis ≥33%. Median BMI was 26 kg/m2 (16–54 kg/m2. 94 patients developed a major complication (18.7%. BMI ≥ 25 kg/m2 (P=0.001 and diabetes (P=0.018 were associated with steatosis ≥33%. Only insulin dependent diabetes was a risk factor for major complications (P=0.028. Age, male gender, hypoalbuminaemia, synchronous bowel procedures, extent of resection, and blood transfusion were also independent risk factors. Conclusions. Liver surgery in the presence of steatosis, elevated BMI, and non-insulin dependent diabetes is not associated with major complications. Although diabetes requiring insulin therapy was a significant risk factor, the major risk factors relate to technical aspects of surgery, particularly synchronous bowel procedures.

    Glomerular filtration rate (GFR), renal plasma flow (RPF) and kidney volume were measured in thirteen male subjects (mean age 30 years) with short-term insulin-dependent diabetes (mean duration of disease 2.4 years) and fourteen normal male subjects (mean age 29 years). GFR and RPF were measured...... by constant infusion technique using I125-iothalamate and 131I-hippuran. Kidney size was determined by means of ultrasound. GFR, RPF and kidney volume were increased in the diabetic patients compared to the normal controls, 144 versus 113 ml/min X 1.73 m2 (p less than 0.0005), 627 versus 523 ml/min X 1.73 m2...... (p less than 0.0025) and 278 versus 224 ml/1.73 m2 (p less than 0.0005) respectively.

    Full Text Available Background/Aim. The aim of this study, which included patients with insulin-dependent diabetes mellitus, was to determine the influence of the application of various treatment modalities (intensive or conventional on the total plasma antioxidative capacity and lipid peroxidation intensity expressed as malondialdehyde (MDA level, catalase and xanthine oxidase activity, erythrocyte glutatione reduced concentration (GSH RBC, erythrocyte MDA level (MDA RBC, as well as susceptibility of erythrocyte to H2O2-induced oxidative stress. Methods. This study included 42 patients with insulin-dependent diabetes mellitus. In 24 of the patients intensive insulin treatment was applied using the model of short-acting insulin in each meal and medium- acting insulin before going to bed, while in 18 of the patients conventional insulin treatment was applied in two (morning and evening doses. In the examined patients no presence of diabetes mellitus complications was recorded. The control group included 20 healthy adults out of a blood doner group. The plasma and erythrocytes taken from the blood samples were analyzed immediately. Results. This investigation proved that the application of intensive insulin treatment regime significantly improves total antioxidative plasma capacity as compared to the application of conventional therapy regime. The obtained results showed that the both plasma and lipoproteines apo B MDA increased significantly more in the patients on conventional therapy than in the patients on intensive insulin therapy, most probably due to intensified xanthine oxidase activity. The level of the MDA in fresh erythrocytes did not differ significantly between the groups on intensive and conventional therapy. The level of GSH and catalase activity, however, were significantly reduced in the patients on conventional therapy due to the increased susceptibility to H2O2-induced oxidative stress . Conclusion. The presented study confirmed positive effect of

    Little information is available about insulin-dependent diabetes mellitus (IDDM) when it occurs among US minorities. The incidence of IDDM among African-American and Hispanic children Diabetes among the first degree relatives of children from both ethnic groups was common, and the most frequently listed co-morbid conditions were asthma and obesity. The risk for IDDM in Chicago is among the highest for both African-origin and Hispanic children worldwide. The prevalence of asthma and obesity parallels the high prevalence of these conditions among non-diabetic children in Chicago. The ongoing epidemic of non-insulin-dependent diabetes mellitus (NIDDM) among African-Americans and US Hispanics is likely to be the reason for the large number of minority IDDM patients who have a first-degree relative with diabetes.

    The association between Down syndrome (DS) and autoimmune endocrinopathies is well established. These disorders become increasingly frequent as children grow older and the onset of one often predisposes to the development of others. However, there are few cases in the literature reporting the simultaneous onset of type 1 diabetes mellitus and hyperthyroidism in children with DS. We describe a case of an 8-year-old girl with DS who presented at the emergency department with hyperglycaemia and ketosis as a primary manifestation of type 1 diabetes mellitus. During the initial investigation, hyperthyroidism was detected, with thyroid-stimulating hormone<0.01 µUI/mL, positive antithyroid antibodies and an increase in thyroid gland on ultrasound. The authors present this case to underline the usefulness of monitoring thyroid function at the diagnosis of diabetes, even without apparent clinical manifestations, and to alert for the possibility of autoimmune endocrine dysfunction in children with DS.

    At the Department of Obstetrics and Gynecology, Perinatal Unit for Diabetes and Fetal Growth, School of Medicine, Zagreb, perinatal care of pregnancies complicated with insulin dependent diabetes melitus (IDDM), has been performed for more than 36 years. The intention of this review is to show our own results in the management of IDDM pregnancies and the latest clinical advances in perinatal care of such pregnancies. Pregnancy complicated with IDDM is at risk because of numerous maternal, fetal and neonatal complications. Recent advances in medicine, especially in diabetology and perinatology, helps clinician avoid or lessen antenatal or perinatal complications in IDDM pregnancies. The main result of improved perinatal care is that today fetal and neonatal mortality in IDDM pregnancy is almost equal to that of healthy pregnant population. Intensive preconceptual care and optimal regulation of IDDM have resulted not only in decreased perinatal mortality but also in a decreased rate of congenital malformation. Tight glycemia control during pregnancy has a beneficial effect on fetal growth. Intensive control of fetal growth, verification of lung maturation at term by amniocenthesis, and control of fetal oxygenation will result in delivery of a mature eutrophic newborn with the lowest rate of neonatal complications possible. Perinatal mortality of less than 2% in IDDM pregnancy can be obtained by planned delivery between 38 and 39 weeks of gestation by either vaginal route or cesarean section, depending on indications. After delivery, intensive care of the newborn is necessary.

    A transient rise in hepatic glucose production (HGP) after an oral glucosa load has been reported in some insulin-resistant states such as in obese fa/fa Zucker rats. The aim of this study was to determine whether this rise in HGP also occurs in subjects with established non-insulin-dependent diabetes mellitus (NIDDM). Glucose kinetics were measured basally and during a double-label oral glucose tolerance test (OGTT) in 12 NIDDM subjects and 12 non-diabetic 'control' subjects. Twenty minutes after the glucose load, HGP had increased 73% above basal in the NIDDM subjects (7.29 +/- 0.52 to 12.58 +/- 1.86 mumol/kg/min, P < 0.02). A transient rise in glucagon (12 pg/ml above basal, P < 0.004) occurred at a similar time. In contrast, the control subjects showed no rise in HGP or plasma glucagon. HGP began to suppress 40-50 min after the OGTT in both the NIDDM and control subjects. A 27% increase in the rate of gut-derived glucose absorption was also observed in the NIDDM group, which could be the result of increased gut glucose absorption or decreased first pass extraction of glucose by the liver. Therefore, in agreement with data in animal models of NIDDM, a transient rise in HGP partly contributes to the hyperglycemia observed after an oral glucose load in NIDDM subjects.

    Full Text Available Abstract Background Free radical mediated oxidative stress is mainly involved in the pathogenesis of diabetic complications. Proteins and lipids are among the prime targets for oxidative stress. In the present study, we evaluated the oxidative stress in chronic IDDM patients by estimating the lipid peroxidation, protein oxidation, and antioxidants status. Subjects and design A total of 35 (15 IDDM + 20 normal healthy children were examined in the study and estimated the lipid peroxidation, protein oxidation, and antioxidants – vitamin A (β-carotene, retinol, vitamin C, vitamin E and enzymatic antioxidants and nitric oxide. Results A statistically significant higher values of protein carbonyl groups and MDA as lipid peroxides were observed in diabetic patients with slight reduction in the synthesis of nitric oxide. It is interesting to note that there was a decrease in the antioxidant levels with corresponding increased protein and lipid oxidation. On PAGE under native conditions, we observed decreased levels of proteins – albumin, transferrin, ceruloplasmin and heptoglobulins and variable GC globulin fractions in IDDM compared to normal healthy controls. Conclusion Hyperglycemia induces the overproduction of oxygen free radicals and consequently increases the protein oxidation and lipid oxidation. A significance difference in the mean plasma concentration of total antioxidant status was observed in IDDM patients. The findings of the present study suggest that diabetes in an altered metabolic state of oxidation-reduction and that it is convenient to give therapeutic interventions with antioxidants.

  8. Abnormal nocturnal blood pressure fall in normotensive adolescents with insulin-dependent diabetes is ameliorated following glycemic improvement

    Full Text Available Lack of the physiological nocturnal fall in blood pressure (BP has been found in diabetics and it seems to be related to the presence of diabetic complications. The present study examined the changes in the nocturnal BP pattern of 8 normotensive insulin-dependent diabetic adolescents without nephropathy following improvement in glycemic control induced by an 8-day program of adequate diet and exercise. The same number of age- and sex-matched control subjects were studied. During the first and eighth nights of the program, BP was obtained by ambulatory BP monitoring. After a 10-min rest, 3 BP and heart rate (HR recordings were taken and the mean values were considered to represent their awake values. The monitor was programmed to cuff insufflation every 20 min from 10:00 p.m. to 7:00 a.m. The glycemic control of diabetics improved since glycemia (212.0 ± 91.5 to 140.2 ± 69.1 mg/dl, P<0.03, urine glucose (12.7 ± 11.8 to 8.6 ± 6.4 g/24 h, P = 0.08 and insulin dose (31.1 ± 7.7 to 16.1 ± 9.7 U/day, P<0.01 were reduced on the last day. The mean BP of control subjects markedly decreased during the sleeping hours of night 1 (92.3 ± 6.4 to 78.1 ± 5.0 mmHg, P<0.001 and night 8 (87.3 ± 6.7 to 76.9 ± 3.6 mmHg, P<0.001. Diabetic patients showed a slight decrease in mean BP during the first night. However, the fall in BP during the nocturnal period increased significantly on the eighth night. The average awake-sleep BP variation was significantly higher at the end of the study (4.2 vs 10.3%, P<0.05 and this ratio turned out to be similar to that found in the control group (10.3 vs 16.3%. HR variation also increased on the eighth night in the diabetics. Following the metabolic improvement obtained at the end of the period, the nocturnal BP variation of diabetics was close to the normal pattern. We suggest that amelioration of glycemic control may influence the awake-sleep BP and HR differences. This effect may be due at least in part to an attenuated

    To study the glycaemic effect of various Danish bread types in insulin-dependent diabetic subjects (IDDM) we looked at the incremental blood glucose areas after isocaloric meals of grained wholemeal rye bread, wholemeal bread (graham bread) and white bread in seven C-peptide negative diabetic subjects. Furthermore, we evaluated the glycaemic potency of dried fruits by exchanging 40 per cent of the starch of grained wholemeal rye bread as dried figs. Prior to the meal intake the patients had attained normoglycaemia and isoinsulinaemia by means of the artificial pancreas. The four test meals containing 50 g of available carbohydrate were taken in random order. The postprandial blood glucose response areas after whole-meal bread (1037 +/- 113 mM X 180 min) and white bread (1021 +/- 100 mM X 180 min) were significantly higher than that to grained wholemeal rye bread (786 +/- 66 mM X 180 min, P less than 0.05). Exchange of 40 per cent of the complex carbohydrate as grained wholemeal rye bread with simple sugars, such as figs, had no influence on the blood glucose response (786 +/- 66 mM X 180 min vs. 766 +/- 56 mM X 180 min). Constant and identical serum-free insulin levels at 30 mU/l and similar amounts of glucose lost in the urine were found after the four test meals. In conclusion, the difference in extraction rate of wheat in the form of white flour (0, 7) and wholemeal flour (1, 0) was not reflected in the glycaemic responses in IDDM subjects. Grained wholemeal rye bread is a fibre-rich, cheap nutrient which elicits a significantly lower glycaemic response compared to wholemeal and white bread and can be recommended to diabetic subjects.

    To determine the effects of very-low-calorie diets on the metabolic abnormalities of diabetes and obesity, we have studied 10 obese, non-insulin-dependent diabetic (NIDDM) and 5 obese, nondiabetic subjects for 36 days on a metabolic ward during consumption of a liquid diet of 300 kcal/day with 30 g of protein. Rapid improvement occurred in the glycemic indices of the diabetic subjects, with mean (+/- SEM) fasting plasma glucose falling from 291 +/- 21 to 95 +/- 6 mg/dl (P less than 0.001) and total glycosylated hemoglobin from 13.1 +/- 0.7% to 8.8 +/- 0.3% (P less than 0.001) (normal reference range 5.5-8.5%). Lipid elevations were normalized with plasma triglycerides reduced to less than 100 mg/dl and total plasma cholesterol to less than 150 mg/dl in both groups. Hormonal and substrate responses were also comparable between groups with reductions in insulin and triiodothyronine and moderate elevations in blood and urinary ketoacid levels without a corresponding rise in free fatty acids. Electrolyte balance for sodium, potassium, calcium, and phosphorus was initially negative but approached equilibrium by completion of the study. Magnesium, in contrast, remained in positive balance in both groups throughout. Total nitrogen loss varied widely among all subjects, ranging from 70 to 367 g, and showed a strong positive correlation with initial lean body mass (N = 0.83, P less than 0.001) and total weight loss (N = 0.87, P less than 0.001). The nondiabetic group, which had a significantly greater initial body weight and lean body mass than the diabetic group, also had a significantly greater weight loss of 450 +/- 31 g/day compared with 308 +/- 19 g/day (P less than 0.01) in the diabetic subjects. The composition of the weight lost at completion was similar in both groups and ranged from 21.6% to 31.3% water, 3.9% to 7.8% protein, and 60.9% to 74.5% fat. The contribution of both water and protein progressively decreased and fat increased, resulting in unchanged caloric

    The effects of various sources of dietary fibre on the high glycaemic index of an Israeli ethnic food, melawach, were investigated in subjects with non-insulin-dependent diabetes mellitus (NIDDM). Locust-bean (Ceratonia siliqua) gum significantly decreased the glucose response to, and glycaemic index of, melawach in these diabetic subjects (P 30 kg/m2, whereas insulinaemic response decreased. The results indicate that foods containing the same nutrients in almost the same amounts, but differing in added dietary fibre, lead to different physiological responses in diabetic subjects. Furthermore, insulin response should be considered when fibre is incorporated into the diabetic's diet.

    Cortisol and growth hormone (GH) responses to a 100 g oral glucose load were measured in 85 Indian patients with non-insulin-dependent diabetes in the young (NIDDY) and 50 reference subjects; in 16 patients and 12 reference subjects the glucagon responses were also assessed. Fasting serum cortisol and plasma glucagon levels were significantly higher in the NIDDY group (P less than 0.001); in contrast, GH levels in the NIDDY patients were significantly lower (P less than 0.01). Plasma glucagon was only significantly suppressed 150 minutes after oral glucose loading in the NIDDY group, in contrast to the reference group, which showed maximum suppression at 90 minutes; at all time intervals plasma glucagon levels were significantly higher in the NIDDY patients. Obesity did not affect fasting plasma glucagon levels. In response to the oral glucose load serum cortisol levels in the NIDDY patients were suppressed in parallel with those in the reference group but remained significantly higher throughout the period of observation at all time intervals. Obese NIDDY patients had higher fasting cortisol levels, but their response to orally administered glucose was no different from that of the NIDDY group as a whole. GH suppression by oral glucose in NIDDY patients was less than that in the reference group, and the rebound rise occurred earlier. Obese NIDDY patients had higher fasting GH levels than their non-obese counterparts, but responses to the glucose load were not different.

    Insulin-dependent diabetes mellitus (IDDM) is one of the most common chronic diseases. It is an autoimmune disease. Genes contributing the most for development of IDDM are located on chromosome 6p21.3 in the region called the major histocompatibility complex (MHC). HLA-DQ8/DR4 and DQ2/DR3 have shown positive association with IDDM, while DQ6 has negative association with IDDM in most Caucasian populations. The location of the tumor necrosis factor alpha (TNF-alpha) gene in the MHC suggests the role of TNF in the etiology of IDDM as an autoimmune disease. The TNF region contains several polymorphisms that are associated with different levels of TNF-alpha production and susceptibility to autoimmune and infectious diseases. Ninety-two Latvian IDDM patients corresponding to WHO diagnostic criteria and 107 unrelated age- and sex-matched healthy controls were analyzed for the frequency of TNF-alpha alleles to test the hypothesis that TNF-alpha is associated with IDDM. We found that TNF-alpha microsatellite allele 2 is associated with IDDM, 29/92 (32%), versus 14/107 (13%) in healthy controls. The test of the strongest association of the MICA A5 allele and TNF-alpha allele 2 with IDDM showed that both are independently associated with the disease.

    Forty-four patients with non-insulin-dependent diabetes mellitus (NIDDM) were included in this study. Radionuclide-labelled solid meals were used to calculate gastric emptying times (GETs). The carbon-14 urea breath test ({sup 14}C-UBT) was used to diagnose Helicobacter pylori (HP) infection. The patients were separated into groups according to the following two criteria: (1) HP infection was diagnosed on the basis of a {sup 14}C-UBT value of {>=}1.5; (2) the GET was defined as abnormal when it was {>=}117.1 min. The results showed that 61% (27/44) of the NIDDM patients had an HP infection, and 59% (26/44) had an abnormal GET. The incidence of abnormal GET in positive {sup 14}C-UBT patients (62%) was higher than that in negative {sup 14}C-UBT patients (56%). Similarly, the incidence of positive {sup 14}C-UBT in abnormal GET cases (62%) was higher than that in normal GET cases (56%). However, according to chi-square tests the differences were not significant. In conclusion, no significant relationship between HP infection and GET was found in patients with NIDDM. (orig.)

    Full Text Available Abstract Background The association of insulin-dependent diabetes mellitus (IDDM and celiac disease (CD has been widely reported in children but the relationship between the two conditions is incompletely understood. Moreover, specific studies on intestinal biopsies of patients with the association of the two diseases are still lacking. Methods We studied the ultrastructure of the duodenal mucosa in 12 patients with both IDDM and CD. Results All patients had either total or partial atrophy of duodenal mucosa. In seven subjects, an accumulation of electrondense granules in the apical cytoplasm of groups of enterocytes was found. In four of them, a double population of granules existed (mean diameter: 400-800 nm and 100-200 nm respectively showing a biphasic pattern. In the other three patients, only smaller granules (100- 200 nm were found in the enterocytes. Conclusions The present work suggests that patients with IDDM/CD may represent a subgroup in the context of the CD population. Intestinal biopsies of such individuals often show accumulation of electrondense granules in the apical cytoplasm of enterocytes that can be interpreted as incomplete gastric metaplasia.

    We conducted a randomized, prospective study to assess the effect of i.v. insulin on blood glucose control, development of ketone bodies and hormonal changes in 60 well-controlled, non-insulin-dependent diabetics (NIDDM) undergoing major surgery. In group A, patients were given only 0.9% saline; in group B, patients were given insulin as a continuous i.v. infusion (1.25 u. h-1); in group C, patients were given insulin 10 u. i.v. boluses every 2 h. Patients in all three groups were given insulin 5 u. when their intraoperative blood glucose concentration increased to greater than 11.1 mmol litre-1. Blood glucose concentrations were measured every 15 min, from just before induction of anaesthesia to 2 h after surgery. Plasma lactate, pyruvate, ketone body, C-peptide and counter-regulatory hormone concentrations were also measured. Blood glucose concentrations in the three groups did not differ significantly. There was a mild-to-moderate increase in plasma ketone body concentrations in group A, but without any deleterious consequences. Plasma C-peptide concentrations decreased significantly in groups B and C, especially in patients given bolus injections of insulin. Plasma growth hormone concentrations also increased significantly in group B and C patients. This study indicated that the "no insulin--no glucose" regimen was a simple, effective way to control blood glucose in well-controlled NIDDM patients, provided blood glucose was measured frequently and insulin used appropriately.

We assessed the effect of voglibose (alpha-glucosidase inhibitor) administration before the evening meal on nocturnal hypoglycemia in IDDM patients with intensive insulin therapy. Ten IDDM patients received 0.3 mg voglibose just before the evening meal for 5 days. The diet and insulin regimen were not changed throughout the study. Nocturnal plasma glucose levels (10 PM, 3 AM, and 7 AM) were studied in these patients before and during voglibose administration. Blood glucose levels were measured at 3 AM before and during voglibose treatment. The mean plasma glucose level at 3 AM was 3.4+/-0.4 mmol/L before voglibose treatment and 7.3+/-1.0 mmol/L during treatment. Plasma glucose at 3 AM was elevated in 9 of 10 patients with voglibose. The decrease in plasma glucose from 10 PM to 3 AM was 6.5+/-0.8 mmol/L before voglibose administration but 3.2+/-0.9 mmol/L during treatment (P hypoglycemia rate was 52% (17 of 33 nights) before voglibose administration but only 9.1% (3 of 33 nights) during treatment. We conclude that voglibose administration before the evening meal improves nocturnal hypoglycemia in IDDM patients with intensive insulin therapy.

    Acetylcholinesterase (AChE) expression is pivotal during apoptosis.Indeed,AChE inhibitors partially protect cells from apoptosis.Insulin-dependent diabetes mellitus (IDDM)is characterized in part by pancreatic β-cell apoptosis.Here,we investigated the role of AChE in the development of IDDM and analyzed protective effects of AChE inhibitors.Multiple low-dose streptozotocin (MLD-STZ) administration resulted in IDDM in a mouse model.Western blot analysis, cytochemical staining, and immunofluorescence staining were used to detect AChE expression in MIN6 cells,primary β cells,and apoptotic pancreatic β cells of MLD-STZ-treated mice.AChE inhibitors were administered intraperitoneally to the MLD-STZ mice for 30 days.Blood glucose,plasma insulin,and creatine levels were measured,and glucose tolerance tests were performed.The effects of AChE inhibitors on MIN6 cells were also evaluated.AChE expression was induced in the apoptotic MIN6 cells and primary β cells in vitro and pancreatic islets in vivo when treated with STZ.Induction and progressive accumulation of AChE in the pancreatic islets were associated with apoptotic β cells during IDDM development.The administration of AChE inhibitors effectively decreased hyperglycemia and incidence of diabetes,and restored plasma insulin levels and plasma creatine clearance in the MLD-STZ mice.AChE inhibitors partially protected MIN6 cells from the damage caused by STZ treatment.Induction and accumulation of AChE in pancreatic islets and the protective effects of AChE inhibitors on the onset and development of IDDM indicate a close relationship between AChE and IDDM.

    Aim: To investigate the effect and underlying mechanisms of inunune-tolerance induced by the adoptive transfer of bone marrow (BM)-derived dendritic cells (DC) in insulin-dependent diabetes mellitus (IDDM) mice. Methods: The IDDM model was established by a low dose of streptozotocin (STZ) in Balb/c mice. Two DC subpopulations were generated from the BM cells with granulocyte-macroph-age colony-stimulating factor with or without interleukin-4. The purity and the T cell stimulatory capability of DC were identified. These cells were used to modu-late autoimmune response in pre-diabetic mice. Blood glucose was examined weekly; pancreas tissues were taken for histopathological analysis, and CD4+ T cells were isolated to detect lymphocyte proliferation by MTT assay and the ratio of CD4+CD25+ T cells by fluorescence-activated cell sorting (FACS). The cytokine secretion was determined by ELISA analysis. Results: Two DC subsets were generated from BM, which have phenotypes of mature DC (mDC) and immature DC (iDC), respectively. The level of blood glucose decreased significantly by transferring iDC (P<0.01) rather than mDC. Less lymphocyte infiltration was ob-served in the islets, and pancreatic structure was intact. In vitro, proliferation of lymphocytes decreased and the proportion of CD4+CD25+ T cells increased remarkably, compared with the mDC-treated groups (P<0.05), which were associ-ated with increased level of the Th2 cytokine and reduced level of the Th1 cytokine after iDC transfer. Conclusion: Our data showed that iDC transfer was able to confer protection to mice from STZ-induced IDDM. The immune-tolerance to IDDM may be associated with promoting the production of CD4+CD25+ T cells and inducing regulatory Th2 responses in vivo.

    Purpose: To investigate the factors related to the development of cataract in patientswith non-insulin dependent diabetes mellitus(NIDDM).Methods: 792 NIDDM patients received ophthalmologic examinations including visualacuity, external status of the eyes, slit lamp microscopy and ophthalmoscopy. Glucose,urea nitrogen (BUN), creatinine (Cr), urine acid (UA), N-acetyl-β2-D-glucosaminidase(NAG), β2-microglobulin(β2-MG) and serum albumin in blood were quantitativelytested. Glucose, pH value, protein, cells, cast and ketobodies in urine were assayed.Diagnosis of cataract was based on lens opacities classification system Ⅱ. Any patientmeeting "NⅡ", "CⅡ" or "PⅡ" level was diagnosed as cataract.Results: The incidence of cataract in this group of NIDDM was 62.37 % (494/792),which significantly related to the duration of the disease course, but not to the sex of thepatient. The occurrence rate of cataract in patients suffering from NIDDM of less thanfive years duration, from five to ten years, and more than ten years was 49.67 % (228/459), 71.84 % (125/174), and 88.68 % (141/159), respectively. The occurrence ofcataract in patients diagnosed of the disease from five to ten years and more than tenyears was much higher than that of those with the course of the disease less than fiveyears( P < 0.05 and P < 0. 001, respectively) . Rising concentrations of blood ureanitrogen, creatinine, glycosylated hemoglobin HbA1c(G-HbA1c), N-acetyl-β2-D-glucosaminidase(NAG) and β2-microglobulin(β2-MG) indicated malfunction of thekidneys, and the rate of cataract occurrence in these patients was higher.Conclusion: This study indicates that prolongation of the duration of non-insulindependent diabetes mellitus, renal dysfunction, as well as poor blood glucose control,may accelerate the development of cataract.

    The autoimmune phenomena associated with destruction of the β cell in pancreatic islets and development of type 1 (insulin-dependent) diabetes mellitus (IDDM) include circulating islet cell antibodies. We have immortalized peripheral blood lymphocytes from prediabetic individuals and patients with newly diagnosed IDDM by Epstein-Barr virus transformation. IgG-positive cells were selected by anti-human IgG-coupled magnetic beads and expanded in cell culture. Supernatants were screened for cytoplasmic islet cell antibodies using the conventional indirect immunofluorescence test on cryostat sections of human pancreas. Six islet cell-specific B-cell lines, originating from a patient with newly diagnosed IDDM, could be stabilized on a monoclonal level. All six monoclonal islet cell antibodies (MICA 1-6) were of the IgG class. None of the MICA reacted with human thyroid, adrenal gland, anterior pituitary, liver, lung, stomach, and intestine tissues but all six reacted with pancreatic islets of different mammalian species and, in addition, with neurons of rat cerebellar cortex. MICA 1-6 were shown to recognize four distinct antigenic epitopes in islets. Islet cell antibody-positive diabetic sera but not normal human sera blocked the binding of the monoclonal antibodies to their target epitopes. Immunoprecipitation of 35S-labeled human islet cell extracts revealed that a protein of identical size to the enzyme glutamate decarboxylase (EC 4.1.1.15) was a target of all MICA. Furthermore, antigen immunotrapped by the MICA from brain homogenates showed glutamate decarboxylase enzyme activity. MICA 1-6 therefore reveal glutamate decarboxylase as the predominant target antigen of cytoplasmic islet cell autoantibodies in a patient with newly diagnosed IDDM.

    Autoimmunity against 65K-glutamate decarboxylase (GAD65), one of two forms of the {gamma}-aminobutyric acid-synthesizing enzyme, is commonly associated with insulin-dependent diabetes mellitus (IDDM). To study the predisposing effect of the GAD65 genotype on IDDM, we performed a case-control study screening an association between a newly-identified GAD65 polymorphism and IDDM in the Japanese population. The identified polymorphism was a microsatellite that was located in an intron near the 3{prime} end of the GAD65 gene consisting of variable numbers of a (CA)-dinucleotide repeat. We amplified the polymorphic region by polymerase chain reaction, and, for each individual in the control group (n=254) and the IDDM group (n=108), determined a pair of (CA)-repeat numbers, each number derived from one or the other of their alleles. In both groups we found 13 allelic variants with different repeat numbers, ranging from 19 to 31 repeats of the (CA) dinucleotide. The most frequent allelic variant in the IDDM group was 20 repeats; (CA){sub 20}. A higher frequency of a genotype containing two (CA){sub 20} alleles (p=0.005) was observed in the IDDM group (41.7%) compared with the control group (26.8%). Odds ratio (a 95% confidence interval) for a heterozygote or a homozygote of (CA){sub 20} versus a subject without (CA){sub 20} was 1.2 (0.66-2.25) and 2.23 (1.18-4.21), respectively. No significant association was observed between the (CA)-repeat genotype and the appearance of anti-GAD antibodies in the patients whose duration of the diabetes was less than 4 years (n=35). Therefore, genetic variations in GAD65 appears to be associated with IDDM susceptibility.

    Exercise training has potential benefits for patients with hyperlipidemia and/or non-insulin dependent diabetes mellitus. In nondiabetic, nonobese subjects with hypertriglyceridemia, exercise training alone increased insulin sensitivity, improved glucose tolerance, and lowered serum triglyceride and cholesterol levels. These improvements did not occur when exercise training alone was given to similar patients with impaired glucose tolerance. In severely obese (X = 125 kg) subjects without diabetes melitus, a 600 calorie diet alone decreased glucose and insulin concentrations and improved glucose tolerance but did not increase insulin sensitivity. The addition of exercise training improved insulin sensitivity. Obese, non-insulin dependent diabetes mellitus subjects on sulfonylurea therapy alone increased insulin levels but failed to improve insulin sensitivity or glucose levels. In contrast, the addition of exercise training to this medication resulted in improved insulin sensitivity and lowered glucose levels. We conclude that exercise training has major effects on lowering triglyceride levels in hyperlipidemic subjects and can potentiate the effect of diet or drug therapy on glucose metabolism in patients with non-insulin dependent diabetes mellitus.

    Full Text Available Acute abdomen in a diabetic child may cause diagnostic dilemma. Acalculous emphysematous cholecystitis (EC, although reported among critically ill or diabetic adults, is an uncommon occurrence in the children. It may complicate the presentation due to its varied manifestations; especially when associated with other concomitant intra-abdominal inflammatory pathologies. We encountered a rare concurrence of acute EC complicated with pericholecystic fluid collection and secondary appendicitis causing non-specific acute abdomen in an 11-year-old obese boy with insulin-dependent diabetes mellitus. Laparoscopy proved to be a highly useful tool in the diagnosis and treatment of this surgical dilemma.

    Susceptibility to non-insulin-dependent diabetes mellitus (NIDDM) is largely genetically determined. In Pima Indians, obesity, insulin resistance, and a low acute insulin response (AIR) to an intravenous glucose infusion are each predictors of the disease. To ascertain whether these phenotypes are genetically determined, we estimated their familiarity in nondiabetic Pima Indians with a maximum-likelihood method. Percentage body fat (PFAT) was highly familial (h{sup 2} = .76), whereas waist/thigh circumference ratio (W/T ratio) was not significantly familial after controlling for PFAT (h{sup 2} = .16). AIR was also highly familial (h{sup 2} = .80 at 10 min), even after controlling for PFAT and insulin action (h{sup 2} = .70). Insulin action at physiologic plasma insulin concentrations was familial (h{sup 2} = .61) but less so after controlling for PFAT and W/T ratio (h{sup 2} = .38). At maximally stimulating insulin concentrations, insulin action was familial (h{sup 2} = .45) and was less influenced by controlling for PFAT and W/T ratio (h{sup 2} = .49). We conclude that in Pima Indians (1) PFAT and AIR are highly familial traits, (2) central distribution of fat is not a familial trait when controlled for PFAT, (3) 38%-49% of the variance in insulin action, independent of the effect of obesity, is familial, and (4) PFAT, AIR, and insulin action are useful traits to study genetic susceptibility to NIDDM. Because genetic parameter estimates are applicable only to the populations from which they were estimated, it is important to determine whether these estimates of familiarities in Pima Indians can be confirmed in other populations before the utility of these traits in searching for NIDDM susceptibility genes in those populations can be fully advocated. 31 refs., 3 tabs.

    Full Text Available Objective: To assess the presence of anxiety disorders and quality of life in patients with insulin-dependent type 2 diabetes. Methods: Case-control study of 996 patients with type 2 diabetes and 2,145 individuals without diabetes. The sole inclusion criterion for the case group was insulin-dependent type 2 diabetes. We compared the case and control groups for sociodemographic variables, laboratory and clinical data, and presence of anxiety disorders. Quality of life was evaluated using the WHOQOL-BREF instrument, and the prevalence of anxiety disorder was evaluated by the Mini International Neuropsychiatric Interview (MINI. Results: Patients with diabetes had a higher prevalence of generalized anxiety disorder, panic disorder, and obsessive-compulsive disorder. The presence of these disorders in combination with type 2 diabetes was associated with worse quality of life in the physical, social, psychological, and environmental domains. Conclusions: This study demonstrates the importance of diagnosing and treating anxiety disorders in patients with diabetes, so as to prevent more serious complications associated with these comorbidities.

    Maturity-onset diabetes of the young (MODY) is a form of non-insulin-dependent diabetes mellitus characterized by an early age of onset, usually before 25 years of age, and an autosomal dominant mode of inheritance. The largest and best-studies MODY pedigree is the TW family. The majority of the diabetic subjects in this pedigree has a reduced and delayed insulin-secretory response to glucose, and it has been proposed that this abnormal response is the manifestation of the basic genetic defect that leads to diabetes. Using DNA from members of the TW family, the authors tested more than 75 DNA markers for linkage with MODY. A DNA polymorphism in the adenosine deaminase gene (ADA) on the long arm of chromosome 20 was found to cosegregate with MODY. The maximum logarithm of adds (lod score) for linkage between MODY and ADA was 5.25 at a recombination fraction of 0.00. These results indicate that the odds are {gt}178,000:1 that the gene responsible for MODY is this family is tightly linked to the ADA gene on chromosome 20q.

    It has been assumed that there is a relationship between periodontal diseases and diabetes mellitus, however the putative periodontal microorganisms in non-diabetes mellitus (non-DM) individuals and non-insulin-dependent diabetes mellitus (NIDDM) patients have not been well studied. In this study, the detection rates of 5 putative periodontal pathogens: Actinobacillus actinomycetemcomitans, Porphyromonas gingivalis, Eikenella corrodens, Treponema denticola, and Candida albicans by polymerase chain reaction (PCR) between NIDDM and non-DM adults were compared. A total of 246 adults were randomly recruited and periodontal parameters including: plaque index (P1I), gingival index (GI), probing depth (PD) and attachment level (AL) were recorded. Subgingival plaque samples were collected by sterile curettes from the most diseased and healthy sites based on PD and AL. The differences in periodontal parameters and microbiological data in healthy and diseased sites between non-DM and NIDDM patients were compared by chi-square analysis. The results showed no significant differences in age, gender, GI, P1I, PD, and prevalence of the 5 microorganisms between the NIDDM and the non-diabetic groups. However, except for A. actinomycetemcomitans, the prevalence of the periodontal microorganisms tested was significantly higher (p albicans may play important roles in the periodontitis of both NIDDM and non-DM individuals, however the etiology of periodontitis in both groups may not be different from each other.

    Insulin-dependent diabetes mellitus (IDDM) HLA class III DRB1-DQA1-DQB1 data from four populations (Norwegian, Sardinian, Mexican American, and Taiwanese) have been analyzed to detect the amino acids involved in the disease process. The combination of sites DRB1 No. 67 and 86; DQA1 No. 47; and DQB1 No. 9, 26, 57, and 70 predicts the IDDM component in these four populations, when the results and criteria of the haplotype method for amino acids, developed in the companion paper in this issue of the journal, are used. The following sites, either individually, or in various combinations, previously have been suggested as IDDM components: DRB1 No. 57, 70, 71, and 86; DQA1 No. 52; and DQB1 No. 13, 45, and 57 (DQB1 No. 13 and 45 correlates 100% with DQB1 No. 9 and 26). We propose that DQA1 No. 47 is a better predictor of IDDM than is the previously suggested DQA1 No. 52, and we add DRB1 No. 67 and DQB1 No. 70 to the HLA DR-DQ IDDM amino acids. We do not claim to have identified all HLA DR-DQ amino acids - or highly correlated sites - involved in IDDM. The frequencies and predisposing/protective effects of the haplotypes defined by these seven sites have been compared, and the effects on IDDM are consistent across the populations. The strongest susceptible effects came from haplotypes DRB1*0301/DQA1*0501/ DQB1*0201 and DRB1*0401-5-7-8/DQA1*0301/DQB1*0302. The number of strong protective haplotypes observed was larger than the number of susceptible ones; some of the predisposing haplotypes were present in only one or two populations. Although the sites under consideration do not necessarily have a functional involvement in IDDM, they should be highly associated with such sites and should prove to be useful in risk assessment. 48 refs., 2 figs., 4 tabs.

    We report here our analysis of HLA class II alleles in 180 Caucasian nuclear families with at least two children with insulin-dependent diabetes mellitus (IDDM). DRB1, DQA1, DQB1, and DPB1 genotypes were determined with PCR/sequence-specific oligonucleotide probe typing methods. The data allowed unambiguous determination of four-locus haplotypes in all but three of the families. Consistent with other studies, our data indicate an increase in DR3/DR4, DR3/DR3, and DR4/DR4 genotypes in patients compared to controls. In addition, we found an increase in DR1/DR4, DR1/DR3, and DR4/DR8 genotypes. While the frequency of DQB1*0302 on DR4 haplotypes is dramatically increased in DR3/DR4 patients, DR4 haplotypes in DR1/DR4 patients exhibit frequencies of DQB1*0302 and DQB1*0301 more closely resembling those in control populations. The protective effect of DR2 is evident in this data set and is limited to the common DRB1*1501-DQB1*0602 haplotype. Most DR2{sup +} patients carry the less common DR2 haplotype DRB1*1601-DQB1*0502, which is not decreased in patients relative to controls. DPB1 also appears to play a role in disease susceptibility. DPB1*0301 is increased in patients (P < .001) and may contribute to the disease risk of a number of different DR-DQ haplotypes. DPB1*0101, found almost exclusively on DR3 haplotypes in patients, is slightly increased, and maternal transmissions of DRB1*0301-DPB1*0101 haplotypes to affected children occur twice as frequently as do paternal transmissions. Transmissions of DR3 haplotypes carrying other DPB1 alleles occur at approximately equal maternal and paternal frequencies. The complex, multigenic nature of HLA class II-associated IDDM susceptibility is evident from these data. 76 refs., 1 fig., 7 tabs.

    We performed {sup 123}I-MIBG (MIBG) myocardial scintigraphy twice in patients with non-insulin-dependent diabetes mellitus (NIDDM) to investigate whether MIBG distribution was improved by pertinent clinical control. To determine the influential factors for MIBG distribution, we investigated the association between various clinical parameters and the serial change in MIBG uptake parameters. Twenty NIDDM patients with no cardiac disorders were evaluated. Planar images were taken at 30 minutes (early) and 3 hours (delayed) after MIBG injection. The heart-to-upper-mediastinum uptake ratio (H/M) and washout ratio (WR) were calculated as parameters for estimating cardiac sympathetic function. Patients were divided into two groups, eight in the improved group and twelve in the unimproved group, according to the serial change in H/M. The mean interval between the baseline and the follow up study was 2.1{+-}0.6 year. Differences between the means of the laboratory data in patients in both groups were compared for the baseline and the follow up study by using the paired t-test. As a means of determining the influential factors for a serial change of MIBG uptake, Fisher's exact test was performed to evaluate the association between the serial change in cardiac MIBG parameters and changes in other clinical parameters, such as blood sugar (BS) control, BS control method (insulin therapy), serum cholesterol control, and severity of diabetic complications. We also analyzed the association between the changes in CV{sub R-R} (coefficient variance of R-R intervals at rest ECG) or NCV (velocity of posterior tibial nerve) and those of other clinical parameters. Associations among these neurological parameters (MIBG parameters, CV{sub R-R} and NCV) were also analyzed. Paired t-tests showed a significant decrease in fasting blood sugar and fructosamine in the improved group in the follow up study compared to those in the baseline study. Nevertheless, Fisher's exact test showed

    Presence of severe autonomic failure (SAF), defined as coincidence of abnormal heart rate turbulence and abnormal deceleration capacity, identifies a group of patients with very poor prognosis among post-infarction patients with diabetes mellitus. However, factors contributing to development of SAF are entirely unknown. Here, we aimed to identify clinical, biochemical, and hemodynamic factors predicting SAF in a consecutive cohort of diabetic patients with coronary artery disease (CAD). Between January 2010 and July 2011, we prospectively enrolled 97 patients with insulin-dependent type 2 diabetes mellitus and stable CAD in sinus rhythm. Heart rate turbulence (as marker of autonomic reflex activity) and deceleration capacity (as marker of autonomic tonic activity) were calculated from 24-hour Holter recordings. Uni- and multivariable logistic regression analysis included duration of diabetes mellitus, diabetic neuropathy, retinopathy, nephropathy, level of HbA(1c), left ventricular ejection fraction (LVEF), brain natriuretic peptide, presence of multivessel disease, and history of myocardial infarction. Ten (10.3%) of the 97 patients exhibited signs of SAF. Patients with SAF were characterized by longer duration of diabetes (25 years vs 15 years), higher prevalence of diabetic neuropathy (70% vs. 36%), retinopathy (80% vs 45%) and nephropathy (90% vs 55%), significantly higher levels of HbA(1c) (9.0% vs 7.4%; P = .002) and a lower LVEF (30% vs.55%; P = .001). On multivariable analysis, LVEF ≤ 35% and HbA(1c) >8% were the only factors which were independently associated with SAF (odds ratios of 23.1 [95% CI, 1.8-287.0]; P = .015 and 6.6 [1.1-40.1]; P = .043). In patients with insulin-dependent type 2 diabetes mellitus and CAD, presence of SAF correlates with both glycemic control and diabetic complications. Impaired LVEF and increased level of HbA(1c) were independently associated with SAF. Copyright © 2012 Elsevier Inc. All rights reserved.

    Seven insulin-dependent diabetic were treated for 24 to 36 hours by intravenous injections of insulin adapted to variations in blood glucose using a fairly voluminous automatic regulation device. This artificial pancreas consists of a modified Technicon blood sugar apparatus which provides continuous estimation of blood glucose using non-haemolysed whole blood by a glucose oxidase method with an inertia time of 6 minutes, a table calculator and a newly developed interpretation and command electronic unit (GlucostatR). Normalisation of blood glucose was obtained for at least 24 hours, during and between meals, during a period following an oral glucose load and throughout the night.

    2016-07-01

    Conclusion: The inhibitory properties of phenolic rich extracts on α-amylase, α-glucosidase, ACE, and Fe2+- and sodium nitroprusside-induced lipid peroxidation in the pancreas could be attributed to the antioxidant properties of the extracts and their phenolic composition. The stronger action of the bound phenolic extract on α-glucosidase may provide the possible bioactivity at the brush border end of the intestinal wall. This study may thus suggest that leaves represent a functional food and nutraceutical in the management of non-insulin dependent diabetes mellitus and hypertension.

    The prevalence of diabetes is rapidly rising all over the globe at an alarming rate. India shelters the highest number of diabetics and is thus known as the 'Diabetes Capital of the World'. The chemical management of diabetes has side effects and hence the present study was undertaken to assess the hypoglycaemic and hypolipidaemic effect of Stevia rebaudiana in patients with type 2 diabetes, non-insulin dependent diabetes mellitus (NIDDM). Its nutritional composition and use as a sweetener substitute were also assessed. Chemical analysis of dried Stevia leaf powder revealed it to be a nutritious herb with a good iron and fibre content. Intervention trials in diabetics revealed that it significantly lowered fasting and post-prandial blood glucose levels. The serum triglycerides and VLDL-C levels were also significantly reduced. Hence it can be said that Stevia can safely be used as an anti-diabetic herb, as a sweetener substitute and may help to prevent cardiovascular diseases in patients with long-standing diabetes. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

    Non-insulin-dependent diabetes mellitus (NIDDM) is the most common form of diabetes in the civilized world. Its consequences include microvascular and macrovascular disease, both of which appear to evolve from a common background of obesity and physical inactivity. The current study was undertaken in obese patients with NIDDM to see whether improvements could be made in glycemic control as well as in many cardiovascular risk factors (obesity, hypertension, lipid abnormalities, and physical inactivity) that are typical of this condition. Fifteen obese insulin-using patients with NIDDM (average body mass index, 34.0) were treated with a 500-calorie formula diet for eight to 12 weeks. Administration of insulin and diuretics was discontinued at the onset of the study. A eucaloric diet was begun at eight to 12 weeks and maintained until Week 24. A behaviorally oriented nutrition-exercise program was instituted at the beginning of the study. Glipizide or placebo was added (randomized) at Week 15 if the fasting plasma glucose level in patients exceeded 115 mg/dl. Patients lost an average of 22 pounds over the course of 24 weeks. Frequency and duration of physical activity increased significantly from baseline, as did the maximal oxygen consumption rate. Glycemic control by 15 weeks (without insulin) was similar to baseline (with insulin). With the addition of glipizide at Week 15, both fasting plasma glucose and glucose tolerance improved significantly. This improvement was not observed with placebo. In addition, both systolic and diastolic blood pressure decreased by about 10 mm Hg. There were no significant changes in the levels of serum lipids or glycosylated hemoglobin. In conclusion, a multifaceted intervention program, employing weight reduction, exercise, diet, and glipizide therapy, can be instituted in insulin-using patients with NIDDM, with improvement in glycemic control and in certain risk factors (hypertension, obesity, physical inactivity) for cardiovascular

    Objective.To assess the role of hypertension and family history of hypertension in the development of nephropathy in patients with non insulin dependent diabetes mellitus (NIDDM). Methods.A retrospective analysis was done on 2 groups of NIDDM patients,one group without proteinuria (urine protein< 300mg/24h,n=106) and the other group with proteinuria (urine protein≥ 500mg/24h,n=106).The 2 groups were matched by age(≤± 3yrs),sex,ethnic and resident place.Some information of these subjects including demographic;history of disease,family history of diseases,lifestyle and behavior style variables was obtained by questionnaire;some variables were measured,including systolic blood pressure (SBP),diastolic blood pressure (DBP),fasting blood glucose (FBG),quantity of protein in 24h urine.Then conditional logistic regression analysis was performed. Results.Some factors,including history of hypertension,longer duration of hypertension,higher levels of the past highest SBP and DBP,were independently associated with the occurrence risk of diabetic nephropathy (DN).Their corresponding odd ratios (OR) with 95% confidence intervals (CI) were 2.00(1.17~3.43),1.25(1.08~1.46),1.38(1.15~1.66),and 1.33(1.09~1.62) respectively,but family history of hypertension was not significantly associated with the development of DN.When the above mentioned relations were respectively adjusted by some possible confounding factors,they still existed. Conclusions.History of hypertension,longer duration of hypertension,higher levels of the past highest SBP and DBP are independent risk factors for DN in Chinese NIDDM patients.

    1989-07-01

    A follow-up study of 116 Type 1 (insulin-dependent) diabetic patients on long-term continuous subcutaneous insulin infusion was conducted after 4.5 +/- 0.2 years. The average HbA1c-value of these patients decreased by 1% to 6.7 +/- 0.1% during this observation period. Typical side effects of continuous subcutaneous insulin infusion such as skin inflammation at the catheter insertion site occurred with similar frequency as has been reported previously by other authors. Diabetic ketoacidosis (0.14 per patient year) and disabling hypoglycaemia (0.1 per patient year, including 0.05 hypoglycaemic coma per patient-year) occurred at substantially lower rates than in other comparable studies with Type 1 diabetic patients at a similar degree of metabolic control. Subgroup evaluation suggested that a normal (less than 5.6%) HbA1c-value at follow-up was associated with increased incidence of disabling hypoglycaemia, whereas poor metabolic control (HbA1c greater than 7.5%) was associated with increased rates of skin complications and hospital treatment for ketoacidosis. Thus, under the policies of this diabetes centre, continuous subcutaneous insulin infusion has proved to be beneficial to a large proportion of experienced adult Type 1 diabetic patients, who voluntarily had opted for, and continued with, this particular mode of insulin treatment.

    Some insulin-dependent diabetic patients present with auto-immune diseases involving extra pancreatic tissues (type 1b diabetes mellitus). The genetic specificity of this syndrome, as opposed to insulin dependent diabetes mellitus (IDDM) free of such associations (Type 1a IDDM) is not clearly established. We have analyzed the HLA-DQB1 and DQA1, loci, after PCR amplification of genomic DNA, in 44 Type 1b IDDM patients, 78 Type 1a IDDM patients and 105 control subjects. No essential difference in HLA-DQ profiles appeared between Type 1b and Type 1a IDDM patients. Both diabetic groups displayed a significant enrichment in DQB1 alleles negative for aspartate at position 57 (Type 1b: 83%; Type 1a: 89%; controls 48%; p < 0.001 vs both patient groups) and in DQB1 Asp 57 negative homozygosity: 71% of Type 1b; 80% of Type 1a; 25% of controls (p < 0.01). This enrichment in DQB1 Asp 57 negative alleles was accounted for by DQB1* 0201 in the Type 1b group, and by DQB1 % 0201 and 0302 in the Type 1a patients. Conversely, alleles DQB1* 0602 and 0301 (DQB1 Asp 57 positive) were protective. Both diabetic groups also displayed a significant enrichment in DQA1 alleles positives for arginine at position 52 (65% of Type 1b; 76% of Type 1a; 50% of control subjects; p < 0.01 and 0.001, respectively, vs controls), and in DQA1 Arg 52 positive homozygotes (48% of Type 1b, 58% of Type 1a, 22% of control subjects; p < 0.01). All differences between diabetic groups and the control group were more pronounced in the case of Type 1a than of Type 1b patients. The HLA-DQ genes shared by Type 1a and Type 1b patients must therefore be closely associated with islet autoimmunity. Genetic differences between Type 1a and Type 1b syndromes, if any, must be investigated in other MHC and non-MHC regions of the genome.

    A retrospective, population-based registry was established in the Comunidad of Madrid, Spain (total population: 4,780,572; under age 15: 1,105,243) to investigate the epidemiology of Type 1 (insulin-dependent) diabetes mellitus. Included were all cases diagnosed with diabetes between 1985 and 1988, with age onset less than 15 years, and using insulin at discharge from hospital. Using the capture-recapture method employing hospital records as the primary source and membership files of the Spanish Diabetic Association as the secondary source, the ascertainment was 90%. The overall annual incidence was estimated to be 11.3/100,000 (Poison 95% confidence interval: 10.3-12.4). There was no temporal increase in incidence, nor was there a significant sex difference in incidence rates, either overall or by year. The seasonal onset pattern showed the highest incidence in winter (December-February) and lowest in summer (June-August) (r = 7.36, p less than 0.05). The age-adjusted (world standard) incidence of 10.9/100,000 was inconsistent with the hypothesis of a north-south gradient in diabetes risk.

    The study was performed to investigate subclinical abnormalities in regional cerebral blood flow (rCBF) in patients with insulin-dependent diabetes mellitus (IDDM) and to correlate them with patients` characteristics. After intravenous injection of technetium-99m hexamethylpropylene amine oxime (HMPAO), tracer uptake of the prefrontal, frontal and parieto-occipital zones was measured with a triple-head single-photon emission tomography (SPET) camera system in 35 IDDM patients outside an episode of hypolycaemia. Tracer uptake values in 16 age- and sex-matched healthy volunteers served as reference values. Compared with healthy subjects, increased tracer uptake of both prefrontal regions and the left frontal region could be shown in diabetes. Tracer uptake was negatively correlated with the duration of diabetes in all investigated regions. In diabetic patients with a disease duration of more than 5 years (n=26), stepwise regression analysis revealed a significant positive correlation between their HbA1c levels and tracer uptake. Long-term diabetic patients with reduced (pre)frontal tracer uptake (n=8) had lower HbA1c levels than those without (8.4%{+-}0.2% vs 9.3%{+-}0.3%, P<0.05) and tended to have more frequently a history of hypoglycaemic coma (6/8 v 6/18, P=0.06). It can be concluded that duration of diabetes contributes to subclinical changes in basal rCBF in IDDM as detected with HMPAO SPET of the brain. The positive correlation between the presence of regional hypoperfusion and lower HbA1c levels in long-term diabetic patients may be interpreted in the light of presumed higher incidence of hypoglycaemia as metabolic control improves.

    Ninety-six patients with insulin-dependent diabetes mellitus (IDDM) and non-proliferative retinopathy were randomized to intensified conventional treatment (ICT) (n = 44) or regular treatment (RT) (n = 52), and followed up for 5 years. HbA1c decreased from 9.5 +/- 0.2% (mean value +/- SEM) to 7.2 +/- 0.1% in the ICT group, and from 9.4 +/- 0.2% to 8.7 +/- 0.1% in the RT group (difference between the groups, P less than 0.001). Retinopathy increased in both groups (P less than 0.001), but after 5 years it was worse in the RT group (P less than 0.05). The urinary albumin excretion rate was higher in the RT group than in the ICT group after 5 years (239.9 +/- 129.7 micrograms min-1 vs. 46.0 +/- 26.1 micrograms min-1, P less than 0.05). Eight RT patients developed manifest nephropathy, compared with none in the ICT group (P less than 0.01). After 5 years the conduction velocities of the sural (P less than 0.05), peroneal (P less than 0.01) and tibial (P less than 0.001) nerves were lower in the RT group. The respiratory sinus arrhythmia was 12.1 +/- 1.2 beats min-1 in the RT group and 16.7 +/- 1.4 beats min-1 in the ICT group at the end of the study (P less than 0.01). The increases in retinopathy (P less than 0.01), nephropathy (P less than 0.01) and neuropathy (P less than 0.001) were all related to the mean HbA1c value during the study. Smoking habits only influenced the progression of retinopathy (P less than 0.05). Serious hypoglycaemia occurred in 34 ICT patients and 29 RT patients (242 and 98 episodes, respectively) (P less than 0.05). Whereas weight was stable in the RT group, the body mass index increased by 5.8% in the ICT group (P less than 0.01). In conclusion, microvascular complications of diabetes were retarded by intensified conventional insulin treatment. However, such treatment increased the frequency of serious hypoglycaemia, and led to an increase in body weight.

    WS diagnosis is often delayed since misdiagnosed as autoimmune diabetes. The rarity of the condition and the absence of other diseases at diabetes diagnosis might make extremely challenging the recognition of WS. However the novel compound heterozygosity for the here reported mutations, seems to confer a mild phenotype among the spectrum of WS manifestations. Copyright © 2016 Elsevier Ireland Ltd.

    PCR primers specific to the human liver fructose-1,6-bisphosphatase (FBP) gene were designed and used to isolate a cosmid clone. Physical mapping of the FBP cosmid by FISH, and genetic mapping of an associated GA repeat polymorphism (PIC = 0.35), located the liver FBP gene to chromosome 9q22.3 with no recombination between FBP and the index markers D9S196 (Z{sub max} = 13.2), D9S280 (Z{sub max} = 11.7), D9S287 (Z{sub max} = 15.6), and D9S176 (Z{sub max} = 14.4). Amplification using FBP exon-specific primers with a YAC contig from this region of chromosome 9 further refined the placement of FBP genomic sequences to an approximately 1.7-cM region flanked by D9S280 and D9S287, near the gene for Fanconi anemia group C. Precise localization of the FBP gene enabled evaluation of FBP as a candidate gene for maturity-onset diabetes of the young (MODY) and non-insulin-dependent diabetes (NIDDM) in both Caucasian and African-American families, using the highly informative markers D9S287 and D9S176. Although FBP is a rate-limiting enzyme in gluconeogenesis, using both parametric and nonparametric analysis there was no evidence for linkage of FBP to diabetes in these families. 30 refs., 4 figs., 2 tabs.

    One of the characteristics of non-insulin-dependent diabetes mellitus (NIDDM) is the presence of insulin. Most NIDDM patients have a normal sequence of the insulin receptor, indicating that, if insulin-receptor mutations contribute to the development of NIDDM, they will be present only in a minor fraction of the NIDDM population. The goal of the present study was to examine whether insulin-receptor mutations contribute to the development of NIDDM. We examined 161 individuals with NIDDM and 538 healthy controls from the population-based Rotterdam study for the presence of mutations in the insulin-receptor gene by SSCP. A heterozygous mutation changing valine-985 into methionine was detected in 5.6% of diabetic subjects and in 1.3% of individuals with normal oral glucose tolerance test. Adjusted for age, gender, and body-mass index, this revealed a relative risk for diabetes of 4.49 (95% confidence interval 1.59-12.25) for Met-985 carriers. When the total study group was analyzed, the prevalence of the mutation increased with increasing serum glucose levels (test for trend P < .005). We conclude that the Met-985 insulin-receptor variant associates with hyperglycemia and represents a risk factor for NIDDM. 30 refs., 3 figs., 1 tab.

    At the Ulm University Hospital 43 type-1-diabetes patients took part in a structured in-patient diabetes education program during a 12-day hospitalization period. 27 of the patients received an additional motivational support program which addressed psychological and social impediments related to the topics of the structured diabetes education program. 16 patients underwent the structured diabetes education program only. Motivational support aimed at reducing the specifically addressed sociopsychological barriers. Thus, the effects of the structured diabetes education program should be stabilized and an optimal outcome insured. All patients were asked to complete a questionnaire before, right after and 3 months after the program. Glycosylated hemoglobin (HbAlc) was evaluated before and 3 months after the program. Patients who underwent the motivational support program still felt 3 months after completion of the program that metabolic control was important, whereas patients without motivational support did not. Metabolic control--as indicated by measurement of glycosylated hemoglobin--could be maintained in the patient group with motivational support. Although their blood glucose levels had been in the normal range to start with. These encouraging results suggest implementation of a motivational support program into standard diabetes education programs for type-I-diabetes patients.

    A number of experimental and clinical findings have consistently demonstrated the protective effects of Pycnogenol (PYC) in the management of diabetes. However, the protective mechanism by which PYC provides protection in a model type I diabetes has not been studied. This study examines the beneficial effect of PYC on hyperglycemia, inflammatory markers, and oxidative damage in diabetic rats. We also evaluated the possible mechanism of action of PYC which might be that it stimulates beta islet expression, which has been implicated in the process of insulin secretion and diabetes management. Diabetes was induced in rats by an intraperitoneal injection of streptozotocin (STZ; 60 mg/kg body weight) followed by free access to 5 % glucose for the next 24 h. Four days after STZ injection, rats were supplemented with PYC (10 mg/kg body weight) for 4 weeks. At the end of the experiment, blood was drawn, and rats were then sacrificed, and their livers and pancreases were dissected for biochemical and histological assays. The level of fasting blood glucose and glycosylated hemoglobin significantly increased but amylase, insulin, and hepatic glycogen level decreased in the STZ group. PYC significantly augmented these effects in STZ + PYC group. The STZ group showed elevated level of nitric oxide, tumor necrosis factor-α, and interleukin-1beta in serum which were decreased by PYC treatment. Moreover, PYC significantly ameliorated increased thiobarbituric reactive substances, protein carbonyl, and decreased levels of glutathione, glutathione-s-transferase, and catalase activity in the liver and pancreas of the STZ rats. Histopathological and immunohistochemical examination also revealed a remarkable protective effect of PYC. The study suggests that PYC is effective in reducing diabetic-related complications in a type I model of diabetes and might be beneficial for the treatment of diabetic patients.

  11. Antibiotics in early life alter the gut microbiome and increase disease incidence in a spontaneous mouse model of autoimmune insulin-dependent diabetes.

    Sophie Candon

    Full Text Available Insulin-dependent or type 1 diabetes is a prototypic autoimmune disease whose incidence steadily increased over the past decades in industrialized countries. Recent evidence suggests the importance of the gut microbiota to explain this trend. Here, non-obese diabetic (NOD mice that spontaneously develop autoimmune type 1 diabetes were treated with different antibiotics to explore the influence of a targeted intestinal dysbiosis in the progression of the disease. A mixture of wide spectrum antibiotics (i.e. streptomycin, colistin and ampicillin or vancomycin alone were administered orally from the moment of conception, treating breeding pairs, and during the postnatal and adult life until the end of follow-up at 40 weeks. Diabetes incidence significantly and similarly increased in male mice following treatment with these two antibiotic regimens. In NOD females a slight yet not significant trend towards an increase in disease incidence was observed. Changes in gut microbiota composition were assessed by sequencing the V3 region of bacterial 16S rRNA genes. Administration of the antibiotic mixture resulted in near complete ablation of the gut microbiota. Vancomycin treatment led to increased Escherichia, Lactobacillus and Sutterella genera and decreased members of the Clostridiales order and Lachnospiraceae, Prevotellaceae and Rikenellaceae families, as compared to control mice. Massive elimination of IL-17-producing cells, both CD4+TCRαβ+ and TCRγδ+ T cells was observed in the lamina propria of the ileum and the colon of vancomycin-treated mice. These results show that a directed even partial ablation of the gut microbiota, as induced by vancomycin, significantly increases type 1 diabetes incidence in male NOD mice thus prompting for caution in the use of antibiotics in pregnant women and newborns.

    A genetic and epidemiological survey of non-insulin-dependent diabetes mellitus (NIDDM) was conducted among the Mexican Americans residing in three socioeconomically distinct areas of San Antonio, Texas: a low socioeconomic (SES) traditional area (barrio), a middle SES, ethnically balanced area (transitional), and a high SES, predominantly Anglo area (suburb). Seventeen polymorphic markers were used to relate the prevalences of NIDDM with the extent of Amerindian ancestry of 1,237 Mexican Americans of these three residential areas. While only the RH and haptoglobin loci showed evidence of association with NIDDM, an admixture analysis of the combined allele frequency data revealed a pattern of decreasing NIDDM prevalence with increasing socioeconomic status (as approximated by neighborhood of residence) and a parallel decrease in Amerindian ancestry. The rank-order correlation between NIDDM prevalence and Amerindian admixture is 0.943 (P less than .001) for the crude prevalence rate and 0.829 (P less than .02) for the age-adjusted rate. Nested gene diversity analysis revealed that the heterogeneity of allele frequencies is more pronounced when individuals were classified by their NIDDM disease status as compared to the classification by neighborhood. Estimation of Amerindian ancestry of each individual did not reveal any significant change in the shape of the distributions of individual admixture proportions in diabetics as compared to the controls. Nevertheless, the results suggest that genetic factors partially explain the differences in NIDDM prevalence observed between the Mexican American and Anglo populations in the southwestern United States.

    Full Text Available Type 1 diabetes is caused by autoreactive T cells that destroy pancreatic beta cells. Animal models suggested that a CD4+CD25+ population has a regulatory function capable of preventing activation and effector functions of autoreactive T cells. However, the role of CD4+CD25high T cells in autoimmunity and their molecular mechanisms remain the subject of investigation. We therefore evaluated T regulatory cell frequencies and their PD-1 expression in the peripheral blood of long-standing diabetics under basal conditions and after CD3/CD28 stimulation. Under basal conditions, the percentages of T regulatory cells were significantly higher while that of T effector cells were significantly lower in patients than in controls. The ratio of regulatory to effector T cells was higher in patients than that in controls, suggesting that T regulatory cells were functional in patients. Percentages of total PD-1+, PD-1low and PD-1high expressing T regulatory cells did not change in patients and in controls. After stimulation, a defect in T regulatory cell proliferation was observed in diabetics and the percentages of total PD-1+, PD-1low and PD-1high expressing cells were lower in patients. Our data suggest a defective activation of T regulatory cells in long-standing diabetics due to a lower expression of PD-1 on their surface.

    This study was undertaken to examine the effects of aldose reductase inhibitor (ARI) and vitamin B{sub 12} (VB12) on myocardial uptake of iodine-123 metaiodobenzylguanidine (MIBG) in patients with diabetic autonomic disorder. Myocardial scintigraphy using {sup 123}I-MIBG was performed on 20 healthy volunteers (controls) and 56 patients with non-insulin-dependent diabetes mellitus (NIDDM), in order to obtain the heart/mediastinum ratio in the initial (HMi) and the delayed images (HMd), and the washout rate (%WR). Thirty-four of the 56 NIDDM patients could be diagnosed as having diabetic autonomic disorder by evaluating their scintigraphic findings in comparison with the controls. Seventeen of these 34 patients received 150 mg/day of epalrestat (ARI group) in three divided doses before meals, and the other 17 received 1.5 mg/day of mecobalamin (VB12 group) in three divided doses after meals, for 3-5 months. According to the presence or absence of clinical symptoms of autonomic or peripheral somatic nerve disorder, the patients were subclassified into four groups. group 1=patients, with autonomic symptoms or somatosensory disorder in the ARI group; group 2=patients without autonomic symptoms or somatosensory disorder in the ARI group; group 3=patients with autonomic symptoms or somatosensory disorder in the VB12 group; and group 4=patients without autonomic symptoms or somatosensory disorder in the VB12 group. After completion of the treatment, myocardial scintigraphy was performed again. Comparing the results obtained before and after the treatment, it was seen that ARI improved only the HMi in group 1 (P=0.046), whereas VB12 significantly improved HMi in the group 3 (P=0.018) and HMi, HMd and %WR in group 4 (P=0.043, P=0.018 and P=0.043, respectively). We conclude that VB12 is more efficacious than ARI in the treatment of diabetic cardiovascular autonomic disorder. (orig.) With 2 figs., 3 tabs., 23 refs.

    The present study demonstrates the relationship between urinary albumin excretion rate (AER) and renal structural changes in patients with non-insulin-dependent diabetes mellitus (NIDDM) without clinical proteinuria. Resting AER in 30 control subjects and 67 NIDDM patients were 10.4 +/- 4.8 (mean +/- SD) micrograms/min (range 4.3-21.1 micrograms/min) and 26.4 +/- 32.3 micrograms/min (range 0.4-155 micrograms/min), respectively. Persistent normoalbuminuria (less than 20 micrograms/min) and microalbuminuria (20-200 micrograms/min) were found in 43 (Group A) and 24 (Group B) diabetics. There were significant differences in age, diabetes duration, and frequency of retinopathy (background and proliferative) as well as that of proliferative retinopathy between Groups A and B, but not in the other clinical parameters such as body mass index, HbA1, Ccr, or systolic and diastolic blood pressure (SBP, DBP). When compared with 11 normoalbuminuric patients of similar age and equal diabetes duration to those in Group B, the sole difference in clinical parameters was the existence of proliferative retinopathy in Group B. Renal structural changes were investigated by light microscopy in 14 people in Group A and 13 people in Group B, and additionally in 5 NIDDM patients with both macroalbuminuria (greater than or equal to 200 micrograms/min) and normal or nearly normal renal function (Group C). The diffuse glomerular lesion (Gellman's classification) was grade I or II in A, II or III in B, and III in C.(ABSTRACT TRUNCATED AT 250 WORDS)

    Although physical activity and exercises are recommended for diabetes, fear of fatigue and resources are often constraints. Rebound exercise on a mini trampoline is a relatively new aerobic exercise and this study evaluated its impact on glycosylated haemoglobin (HbA1c ), fasting plasma glucose (FPG) and body mass index (BMI) for sedentary type 2 diabetic (T2D) individuals from a rural environment. A randomised controlled single-blind, pre- and post-test study in an outreach rural rehabilitation gymnasium. Ninety T2D individuals from rural Nigeria aged 39.44 ± 8.61 attending a diabetic outpatient clinic participated in this study as a control (n = 45) or rebound exercise (n = 45) group. The control group watched videos and read health magazines while the rebound group exercised three times per week for 20-30 min over 9 weeks at moderate intensity of 40-60% of heart rate maximum. Heart and respiratory rates, blood pressure, oxygen saturation, HbA1c , FPG and BMI values were recorded pre- and post-interventions. There were no significant differences between groups at baseline and compliance with rebound exercise was 93% (n = 42). Post 9 weeks there were significant improvements (P exercise group with blood pressure, heart and respiratory rates also increasing during the exercise but without any adverse reactions. Rebound exercise is simple, inexpensive and enjoyable. It can be a beneficial recreational adjuvant exercise for improving HbA1c , FPG and BMI in T2D individuals in a rural environment and reduce health care costs and pharmacological complications associated with diabetes. © 2015 National Rural Health Alliance Inc.

    Milk chocolate is rich in both sucrose and fat, and is therefore considered unsuitable for diabetics. Nevertheless there is little information on the metabolic effects of conventional chocolate or specialized formulations with reduced sucrose content. In the present study six male non-insulin-dependent diabetes mellitus patients (age range 35-60 years; body-mass index less than 28) consumed test meals of chocolate (75 g) on three separate occasions. The control chocolate contained sucrose (45.5% w/w); the test chocolates contained either fructose (45.5% w/w) or isomalt (45.1% w/w). The latter is a sweet disaccharide alcohol which has no glycaemic effect when consumed as a pure compound. Venous blood samples were obtained at 30 min intervals for 5 h, and analysed for glucose, insulin, lactate and triglycerides. All three chocolates provoked a sustained rise in blood glucose, which reached a maximum at 90 min after ingestion and returned to baseline values by 5 h. The highest blood glucose levels occurred after conventional chocolate, and differences were statistically significant at 60 and 90 min (P less than 0.05). The area under the glycaemic curve for isomalt chocolate was 36% smaller than that for conventional chocolate (P less than 0.05), and there were differences in insulin and lactate levels, consistent with the lower glycaemic effect. The glycaemic response to the fructose-based chocolate was also lower than that to control chocolate but the difference was not significant. All three chocolates led to a similar sustained rise in serum triglyceride levels. Isomalt appears to be a palatable alternative sweetener capable of reducing the glycaemic effect of diabetic confectionary.

    The HLA-DQ beta-chain gene shows a close association with susceptibility or resistance to autoimmune insulin-dependent diabetes mellitus (IDDM) and it has been suggested that the amino acid in position 57 may be of pathogenetic importance. To study the expression of the IDDM associated HLA-DQ beta......-chain alleles, we immunized rabbits with 12 to 13 amino acid long peptides representing HLA-DQw7 and -DQw8 allelic sequences, differing only by one amino acid in position 57 being aspartic acid (Asp) and alanine (Ala), respectively. Immunoblot analysis of lymphoblastoid cells showed that several antisera...... recognized a 29-kDa protein, equivalent to the expected molecular size of the HLA-DQ beta-chain to yield two antisera specific for HLA-DQw7 (pos. 57Asp) and three antisera for HLA-DQw8 (pos. 57Ala) positive cells. Analysis of HLA-DR 3/4 positive IDDM patients (n = 24) and controls (n = 19) showed that all...

    Research was performed on a group of 30 patients with non-insulin-dependent diabetes mellitus (NIDDM), who never received antidiabetic medication before, and on a group of 17 healthy adults. The patients were administered treatment with metformin, 1,000 mg/day. Plasmatic and urinary concentration of magnesium have been measured, copper and zinc along with the concentrations of glucose, HDL, LDL, cholesterol, tryglicerides, HbA1c, and total erythrocyte magnesium, in advance and after 3 months of treatment. Data showed significant differences in the NIDDM group vs the control group: for plasma magnesium-1.95 ± 0.19 vs 2.20 ± 0.18 mg/dl, p zinc-67.56 ± 6.21 vs 98.41 ± 20.47 μg/dl, p zinc-1,347.54 ± 158.24 vs 851.65 ± 209.75 μg/24 h, p zinc was inversely correlated with glycemia (r = -0.399, p = 0.029). Our data show a significant action of metformin therapy, by increasing the total intraerythrocyte magnesium concentration and decreasing the urinary magnesium elimination, positively correlated with the decrease of glycemia and HbA1c in NIDDM patients.

    Insulin-dependent diabetes mellitus (IDDM) is one of the most common chronic diseases. It is an autoimmune, polygenic disease, associated with several genes on different chromosomes. The most important gene is human leukocyte antigen (HLA), also known as major histocompatibility complex (MHC), which is located on chromosome 6p21.3. HLA-DQ8/DR4 and DQ2/DR3 are positively associated with IDDM and DQ6 is negatively associated with IDDM in most Caucasian populations. The MICA gene is located in the MHC class I region and is expressed by monocytes, keratinocytes, and endothelial cells. Sequence determination of the MICA gene identifies 5 alleles with 4, 5, 6, and 9 repetitions of GCT or 5 repetitions of GCT with 1 additional insertion (GGCT), and the alleles are referred to as A4, A5, A5.1, A6, and A9. Analysis of allele distribution among 93 Latvian IDDM patients and 108 healthy controls showed that allele A5 of MICA is significantly increased in IDDM patients [33/93 (35%)] compared to healthy controls [22/108 (20%)] (OR = 2.15; P = 0.016). In conclusion, we believe that MICA may play an important role in the etiopathogenesis of IDDM.

    To locate genes predisposing to insulin-dependent diabetes mellitus (IDDM), an autoimmune disorder resulting from destruction of the insulin-producing pancreatic cells, we are testing linkage of IDDM susceptibility to polymorphic markers across the genome using families with two or more IDDM children. A new susceptibility locus (IDDM11) has been localized to chromosome 14q24.3-q31 by detection of significant linkage to microsatellite D14S67, using both maximum likelihood methods D14S67, using both maximum likelihood methods (LOD{sub max} = 4.0 at {theta} = 0.20) and affected sib pair (ASP) methods (P = 1 x 10{sup -5}). This represents the strongest reported evidence for linkage to any IDDM locus outside the HLA region. The subset of families in which affected children did not show increased sharing of HLA genes (HLA sharing {le}50%) provided most of the support for D14S67 linkage (LOD{sub max}4.6 at {theta} = 0.12;ASP P < 5 x 10{sup -6}). There was significant linkage heterogeneity between the HLA-defined subsets of families (P = 0.009), suggesting that IDDM11 may be an important susceptibility locus in families lacking strong HLA region predisposition. 52 refs., 2 figs., 3 tabs.

    Insulin-dependent diabetes mellitus (IDDM) is an autoimmune disease affecting genetically susceptible individuals. A major part of the genetic risk is encoded by HLA class II genes. Strong susceptibility is conferred by the DRB1*04-DQA1*03-DQB1*0302 (hereafter called {open_quotes}DR4-DQ8{close_quotes}) and the DRBI*0301-DQA1*0501-DQB1*0201 (hereafter called {open_quotes}DR3-DQ2{close_quotes}) haplotypes, particularly when they occur together. In an interesting publication it suggests that IDDM patients inherit DR4 from their fathers and DR3 from their mothers more often than vice versa. This has also been suggested elsewhere. Several different mechanisms have been proposed to explain this observation, such as parental imprinting, fetal loss, and maternal effect associated with the presence of the DR3 antigen in the mother. Several studies have shown that children of fathers with IDDM have a higher risk of IDDM than do children of mothers with IDDM. If there is an effect of the parental origin of HLA class II-encoded IDDM susceptibility, this could potentially explain the difference. 19 refs., 2 tabs.

    Affected-sib-pair analyses were performed using 104 Caucasian families to map genes that predispose to insulin-dependent diabetes mellitus (IDDM). We have obtained linkage evidence for D6S446 (maximum lod score [MLS] = 2.8) and for D6S264 (MLS = 2.0) on 6q25q27. Together with a previously reported data set, linkage can be firmly established (MLS = 3.4 for D6S264), and the disease locus has been designated IDDM8. With analysis of independent families, we confirmed linkage evidence for the previously identified IDDM3 (15q) and DDM7 (2q). We also typed additional markers in the regions containing IDDM3, IDDM4, IDDM5, and IDDM8. Preliminary linkage evidence for a novel region on chromosome 4q (D4S1566) has been found in 47 Florida families (P < .03). We also found evidence of linkage for two regions previously identified as potential linkages in the Florida subset: D3S1303 on 3q (P < .04) and D7S486 on 7q (P < .03). We could not confirm linkage with eight other regions (D1S191, D1S412, D4S1604, D8S264, D8S556, D1OS193, D13S158, and D18S64) previously identified as potential linkages. 26 refs., 1 fig., 4 tabs.

    Full Text Available The purpose of this study was to explore the effects of isometric exercises and stretching on postural stability in Non – Insulin Dependent Diabetes Mellitus (NIDDM patients with diffuse symmetrical sensory motor neuropathy. Patients were assigned to an experimental group and amatched control group. The experimental group received isometric exer-cises and stretching three times weekly for 12 weeks in addition to routine medication and dietary advice. A t the end of this period, this group wascompared with the control group, which received routine medication anddietary advice only. Measurements of muscle strength of quadriceps, ham-strings, ankle plantar and dorsiflexors, and Romberg’s test for postural sta-bility were carried out before and after the 12 weeks intervention. The study showed that isometric exercises and stretching for the lower extremities improved postural stability (p = 0.00and strength of the quadriceps (p = 0.001 hamstrings (p = 0.001 dorsiflexors (p = 0.001 plantarflexors (p = 0.001in NIDDM patients with diffuse symmetrical sensory motor neuropathy. This exercise regimen also had a loweringeffect on blood glucose level (p = 0.00.  In conclusion it seems that the simple exercise intervention described in thisstudy may be of benefit to these patients if incorporated into their management programmes.

    GLUT-4 receptor, tumor necrosis factor-alpha (TNF-alpha), essential fatty acids (EFAs) and their metabolites and daf-genes seem to play an important and essential role in the maintenance of glucose homeostasis, and in the pathobiology of obesity and non-insulin dependent diabetes mellitus (NIDDM). Daf-genes encode for proteins which are 35% identical to the human insulin receptor, a transforming growth factor-beta (TGF-beta) type signal and can also enhance the expression of superoxide dismutase (SOD). On the other hand, EFAs and their metabolites can increase the cell membrane fluidity and thus, enhance the expression of GLUT-4 and insulin receptors. In addition, EFAs can suppress TNF-alpha production and secretion and thus, are capable of reversing insulin resistance. Melatonin has anti-oxidant actions similar to daf-16, TGF-beta and SOD. Hence, it is likely that there is a close interaction between GLUT-4, TNF-alpha, EFAs, daf-genes, melatonin and leptin that may have relevance to the development of insulin resistance, obesity, NIDDM, complications due to NIDDM, longevity and ageing.

    It is now believed that the GLUT-4 receptor, tumor necrosis factor-alpha (TNF-alpha), essential fatty acids (EFAs) and their metabolites and daf-genes have an important role in the development of obesity and non-insulin dependent diabetes mellitus (NIDDM). The protein encoded by daf-2 is 35% identical to the human insulin receptor, daf-7 codes a transforming growth factor-beta (TGF-beta) type signal and daf-16 can enhance superoxide dismutase (SOD) expression. EFAs and their metabolites can alter the cell membrane fluidity and enhance the expression of GLUT-4 and insulin receptors. EFAs can suppress TNF-alpha production and secretion, a mechanism that may have relevance to the role of these fatty acids in the pathogenesis of insulin resistance, obesity and NIDDM. Melatonin has anti-oxidant actions similar to daf-16, TGF-beta and SOD. Based on this evidence, it is proposed that GLUT-4, TNF-alpha, EFAs, daf-genes, melatonin and leptin interact with each other in ways which may have relevance to the development or abrogation of insulin resistance, obesity, NIDDM, complications due to NIDDM, longevity and ageing.

    The prevalence of polymorphic amino acids at position 57 of the HLA DQB1 in Kuwaiti children with insulin-dependent diabetes mellitus (IDDM) and nondiabetic controls has been determined using a polymerase chain reaction-sequence-specific primers (PCR-SSP) method. Using this approach, 34/55 (62%) IDDM children were found to be homozygous Ala/Ala and 19/55 (35%) were heterozygous with various combinations. Amongst the IDDM children with heterozygous genotype at codon 57 of HLA DQB1, 6/55 (11%) had Asp/Ala, 8/55 (15%) had Ala/Val, 4/55 (7%) had Ala/Ser and 1/55 had Asp/Val allelic combinations. When considered collectively, the nonaspartate (NA) alleles were represented in 87% of the IDDM cases and only 13% cases had Asp(57) allele in different heterozygous combinations, while none of the IDDM subjects had a homozygous Asp genotype. In nondiabetic controls, homozygous non-Asp (NA) alleles were represented in 44% subjects, 37% of the controls were heterozygous (NA/A) and 19% had a homozygous (A/A) genotype. These differences between the IDDM group and the control group were found to be statistically significant. Our data report one of the highest frequency of NA/NA residues at this locus compared with that from different world populations (Sardinians, Norwegians, US Caucasians, US Blacks and Chinese).

    Blood levels of intermediary metabolites were measured and indirect calorimetry was performed in 10 otherwise healthy, non-insulin-dependent diabetic (NIDDM) patients before, during, and after 30 minutes of moderate exercise on three occasions in random order at weekly intervals with (1) heparin treatment to increase preexercise plasma nonesterified fatty acid (NEFA) levels (HEPARIN); (2) acipimox, a nicotinic acid analogue, to reduce preexercise plasma NEFA levels (ACIPIMOX); and (3) no manipulation of preexercise plasma NEFA levels (NIL). With ACIPIMOX, preexercise blood levels were significantly reduced for NEFAs and glycerol (P ketone bodies during either NIL or HEPARIN increased rapidly postexercise by approximately 90% to 110% for both acetoacetate and 3-hydroxybutyrate (both P growth hormone (hGH) and, perhaps, noradrenaline levels were highest both during and after exercise. The respiratory quotient (RQ) was highest with ACIPIMOX (P < .05 for exercise and postexercise periods compared with the other two treatments), which, compared with NIL, reduced fat oxidation by 27% and 60% and increased carbohydrate oxidation by 29% and 74% during and after exercise, respectively (all P < .05). These changes in substrate oxidation due to ACIPIMOX were almost opposite to those observed with HEPARIN.(ABSTRACT TRUNCATED AT 250 WORDS)

    Full Text Available We studied the pathways of complement activation associated with the islet cell surface antibody (ICSA obtained from sera of 7 patients (age less than 15 years with insulin dependent diabetes mellitus (IDDM. The target cells were 51CR labelled rat islet cells and the complement source was human AB serum. Complement-dependent antibody mediated cytotoxicity (CAMC activity was obtained using the percentage of cytotoxicity. CAMC activity of untreated sera was significantly inhibited by treating with EGTA or EDTA (p less than 0.001. The CAMC activity of EDTA-treated sera was significantly lower than that of EGTA-treated sera (p less than 0.001. In the inactivated human AB serum, it was lower than that of EGTA-treated sera (p less than 0.05, but not different from that of EDTA-treated sera. These results show that the complement activation associated with ICSA in patients occurred not only via the classical pathway but also via the alternative pathway.

    Islet cell antibodies and glutamic acid decarboxylase II (GAD II) antibodies have been discussed in the autoimmune pathogenesis of insulin-dependent diabetes mellitus (IDDM). Hence, immunosuppressants, intravenous immunoglobulins, and plasmapheresis have been used in an effort to modulate autoimmune activity and thereby prevent the destruction of pancreatic beta-cells. We describe the autoantibody (islet cell antibody and GAD II) kinetics and clinical course in a patient with newly diagnosed IDDM treated with a specific immunoglobulin apheresis technique. Five days after the initial diagnosis a 37-year-old patient with IDDM underwent a series of seven immunoglobulin aphereses. Immunoglobulin (IgG, IgA, IgM), islet cell antibody, GAD II, and C-peptide concentrations were monitored for a time course of 74 days. Daily insulin requirements were recorded. One single immunoglobulin apheresis decreased IgG by 66.2 +/- 9.1%, IgA by 66.8 +/- 8.7%, and IgM by 57.7 +/- 12.9%. GAD II antibodies were reduced by 61.9 +/- 12.4%. The islet cell antibody titer declined from 1:32 to 1:4 after the treatment series. There were no relevant changes in the safety parameters determined nor were there any clinical side effects. The efficient decrease in islet cell antibodies and glutamic acid decarboxylase II antibodies in a patient with IDDM encourages further investigations into the impact of this treatment on the clinical course of this autoimmune disorder.

    On the basis of a retrospective study of 71 children followed for 24 months after diagnosis of type I insulin dependent diabetes a fitted mathematical model was constructed for the prediction of the course of beta cell function from the time of diagnosis. Two equations were derived, one for the maximal basal (B-max) and the other for the maximal i.v. glucagon stimulated peak C-peptide (P-max) levels reached during the remission period. The prognostic variables selected for analysis were: peak C-peptide levels at diagnosis (Po), age sex, degree of obesity, pubertal rating, the presence of islet cell antibodies (ICA) and levels of GHb. Multivariate analysis of the data showed that Po (p = 0.0006), puberty (p = 0.041). obesity (p = 0.0021), sex (p = 0.031), ICA (p = 0.0045) and GHb(p = 0.0066) significantly contributed to the prediction formula obtained for B-max whereas the contribution of the above variables for P-max were: Po (p = 0.0019), puberty (p = 0.0187), obesity (p = 0.0058), sex (p = 0.0598), ICA (p = 0.0187) and GHb (p = 0.0027). The residuals of the observed values from the values fitted by the predicted equations served to define two separate groups demonstrating distinct differences in the natural course of beta cell function in type I diabetes. This fitted model may thus be useful in distinguishing between newly diagnosed young patients who will undergo remission, requiring lower insulin doses, and those who have little chance for remission. It might also be helpful in the selection of patients most likely to benefit from immunosuppression or modulation, to maximize the benefit to risk ratio for such patients.

    Previous studies have demonstrated that peripheral blood mononuclear cells (BMC) from type 1 (insulin-dependent) diabetic patients inhibit insulin release (IR) from rat or mouse islet cells in vitro. This phenomenon is of great interest as a model for islet graft rejection. We found that lipopolysaccharide (LPS)-stimulated BMC of healthy donors and type 1 diabetic patients suppress both basal and stimulated insulin secretion. To study whether this inhibition was due to soluble mediators we added supernatants of LPS-stimulated BMC or recombinant human interleukin-1 beta (IL-1) and tumor necrosis factor-alpha (TNF) at concentrations comparable to those found in the supernatants to rat islet cells. The inhibitory effect of BMC on islet cells could be transferred by supernatants of LPS-stimulated BMC. We found that neither IL-1 nor TNF alone inhibit IR from dispersed adult rat islet cells. However, the combination of IL-1 and TNF was highly effective. Ultrafiltration of supernatants of LPS-stimulated BMC through a PM-10 membrane (10 kDa cutoff) deprived the supernatants of the inhibitory activity indicating that only intact IL-1 and TNF (m.w. about 17 kDa), but not smaller IL-1 and TNF fragments, were responsible for the effects on islet cells. These data suggest that activation of BMC and cytokine release at islet graft site may result in an early loss of graft function. Islet transplantation using microcapsules not permeable for molecules with m.w. > 10 kDa would be preferable.

    To determine the rate of severe maternal morbidity related to delivery by delivery mode and to assess if the impact of studied risk factors varies by delivery mode. A register-based study including all women having singleton delivery in Finland in 2007-2011, n = 292,253, data derived from the Finnish Medical Birth Registry and Hospital Discharge Registry. Diagnoses and interventions indicating a severe maternal complication were searched and the mode of delivery was assessed by data linkage. The impact of obesity, maternal age 35 years or more, pre-eclampsia and insulin dependent diabetes on severe maternal morbidity (all severe complications, severe infections and severe) was studied in each mode of delivery and calculated as Odds ratios. The overall incidence of severe complications was 12.8/1,000 deliveries. The total complication rate was lowest in vaginal deliveries (VD) in all risk groups. Obesity increased the risk for all severe complications and severe infections in the total population, but not significantly in specific delivery modes. Age increased the risk of hemorrhage in VD. Pre-eclampsia increased the risk for hemorrhage in all deliveries except elective CS. In women with pre-eclampsia, overall morbidity was similar in VD, attempted VD and elective CS. The presence of any studied risk factor increased the risk for complications within the risk groups by the high proportion of emergency CS performed. An attempt of VD is the safest way to deliver even for high-risk women with the exception of women with pre-eclampsia, who had a similar risk in an attempt of VD and elective CS.

    The IDDM2 component of the genetic susceptibility to insulin-dependent diabetes mellitus (IDDM) has been mapped to chromosome 11p15.5. The exact identity of IDDM2 remains uncertain. It has been suggested that IDDM2 maps within the 5' VNTR (variable number tandem repeat) polymorphism upstream of the insulin gene (INS). This has not been confirmed and a contribution from other INS gene region polymorphisms cannot be excluded. We present INS region genotype data from four racial groups: the Japanese, Hong Kong Chinese, North Indian Asians and Afro-Caribbeans (two groups; one born and resident in the UK, one in Jamaica). These races have not been previously studied with the range of INS region polymorphisms included here. No INS polymorphism was associated with IDDM across all races. These data from this study thus do not identify any INS polymorphism as IDDM2. The Afro-Caribbean race showed a very different distribution of INS genotypes from the other races and novel race-specific INS haplotypes were identified. Analysis of these excluded a contribution to susceptibility to IDDM from the- 23HphI INS polymorphism. An Afro-Caribbean INS haplotype which differed only at the VNTR from the very protective INS haplotype (VPH) identified in white Caucasians was detected. Population analysis of this haplotype will allow direct assessment of the role of the VNTR in susceptibility to IDDM. In conclusion, the diverse Afro-Caribbean TH/INS/IGF2 haplotypes identified in this study will be valuable in mapping IDDM2 more precisely.

    Past cross-sectional studies have suggested that young adults with insulin-dependent (Type 1) diabetes mellitus (IDDM) may experience problems in their close peer relationships. For 10 years, we have followed an onset cohort of children and adolescents with IDDM (n = 57) and an age-matched group who were originally recruited after an acute illness, accident, or injury (n = 54). Now aged 19-26 years, these two groups were compared in terms of their friendship patterns, dating and love experiences, and sense of loneliness. All subjects in both groups had at least one friend. However, the IDDM group reported fewer friendships overall. The difference was accounted for by the number of less intimate friends. The two groups had similar frequencies of current romantic partners (IDDM = 63%; comparison group = 64%). While dating attitude and dating assertiveness did not differ between groups, some differences were found in terms of experiences of a primary love relationship. IDDM patients experienced less trust and sense of intimate friendship in these love relationships. No differences in loneliness were found. The preponderance of our findings indicate that the two groups had similar patterns and experiences of close peer relationships. Thus, the study does not suggest that IDDM leads to serious problems in forming social relationships for these patients during the transition to young adulthood. On the other hand, the IDDM patients' lower level of trust and intimacy within love relationships are consistent with other findings from this study suggesting specific areas of lowered self-worth that appear in social relationships.

Insulin dependent diabetes mellitus (IDDM is believed to be an autoimmune disorder with disturbed glucose/insulin metabolism, requiring life-long insulin replacement therapy (IRT, 30% of patients develop end-organ failure. We present our experience of cotransplantation of adipose tissue derived insulin-secreting mesenchymal stem cells (IS-AD-MSC and cultured bone marrow (CBM as IRT for these patients. Methods. This was a prospective open-labeled clinical trial to test efficacy and safety of IS-AD-MSC+CBM co-transplantation to treat IDDM, approved by the institutional review board after informed consent in 11 (males : females: 7 : 4 patients with 1–24-year disease duration, in age group: 13–43 years, on mean values of exogenous insulin requirement of 1.14 units/kg BW/day, glycosylated hemoglobin (Hb1Ac: 8.47%, and c-peptide levels: 0.1 ng/mL. Intraportal infusion of xenogeneic-free IS-AD-MSC from living donors, subjected to defined culture conditions and phenotypically differentiated to insulin-secreting cells, with mean quantum: 1.5 mL, expressing Pax-6, Isl-1, and pdx-1, cell counts: 2.1×103/μL, CD45−/90+/73+:40/30.1%, C-Peptide level:1.8 ng/mL, and insulin level: 339.3  IU/mL with CBM mean quantum: 96.3 mL and cell counts: 28.1×103/μL, CD45−/34+:0.62%, was carried out. Results. All were successfully transplanted without any untoward effect. Over mean followup of 23 months, they had a decreased mean exogenous insulin requirement to 0.63 units/kgBW/day, Hb1Ac to 7.39%, raised serum c-peptide levels to 0.38 ng/mL, and became free of diabetic ketoacidosis events with mean 2.5 Kg weight gain on normal vegetarian diet and physical activities. Conclusion. This is the first report of treating IDDM with insulin-secreting-AD-MSC+CBM safely and effectively with relatively simple techniques.

    The objectives of this clinical study using iodine-123 metaiodobenzylguanidine (MIBG) scintigraphy were (a) to evaluate cardiac sympathetic denervation in non-insulin-dependent diabetes mellitus (NIDDM) patients with and without hypertension and (b) to investigate the relation between cardiac sympathetic denervation and prognosis in NIDDM patients. We compared clinical characteristics and MIBG data [heart to mediastinum (H/M) ratio and % washout rate (WR)] in a control group and NIDDM patients with and without hypertension. MIBG scintigraphy was performed in 11 controls and 82 NIDDM patients without overt cardiovascular disease except for hypertension (systolic blood pressure {>=}140 and/or diastolic blood pressure {>=}90 mmHg). After MIBG examination, blood pressure was measured regularly in all NIDDM patients. There were significant differences between 65 normotensive and 17 hypertensive NIDDM patients with respect to age (55{+-}11 vs 63{+-}12 years, respectively, P<0.05), prevalence of diabetic retinopathy (12% vs 35%, respectively, P<0.05) and systolic blood pressure (120{+-}12 vs 145{+-}16 mmHg, respectively, P<0.001). The H/M ratio in hypertensive NIDDM patients was significantly lower than in the control group (1.81{+-}0.29 vs 2.27{+-}0.20, respectively, P<0.01). During the follow-up period (18{+-} 12 months), 17 NIDDM patients newly developed hypertension after MIBG examination. There were no significant differences in their clinical characteristics compared with persistently normotensive or hypertensive NIDDM patients. %WR in patients with new onset hypertension was significantly higher than in the control group (30.88%{+-}16.87% vs 12.89%{+-}11.94%, respectively, P<0.05). Moreover, in these patients %WR correlated with duration from the date of MIBG scintigraphy to the onset of hypertension (r=-0.512, P<0.05). Five NIDDM patients died during the follow-up period (four newly hypertensive patients and one normotensive patient). There were significant

    Aims. Insulin dependent diabetes mellitus (IDDM) is believed to be an autoimmune disorder with disturbed glucose/insulin metabolism, requiring life-long insulin replacement therapy (IRT), 30% of patients develop end-organ failure. We present our experience of cotransplantation of adipose tissue derived insulin-secreting mesenchymal stem cells (IS-AD-MSC) and cultured bone marrow (CBM) as IRT for these patients. Methods. This was a prospective open-labeled clinical trial to test efficacy and safety of IS-AD-MSC+CBM co-transplantation to treat IDDM, approved by the institutional review board after informed consent in 11 (males : females: 7 : 4) patients with 1-24-year disease duration, in age group: 13-43 years, on mean values of exogenous insulin requirement of 1.14 units/kg BW/day, glycosylated hemoglobin (Hb1Ac): 8.47%, and c-peptide levels: 0.1 ng/mL. Intraportal infusion of xenogeneic-free IS-AD-MSC from living donors, subjected to defined culture conditions and phenotypically differentiated to insulin-secreting cells, with mean quantum: 1.5 mL, expressing Pax-6, Isl-1, and pdx-1, cell counts: 2.1 × 10(3)/μL, CD45(-)/90(+)/73(+):40/30.1%, C-Peptide level:1.8 ng/mL, and insulin level: 339.3  IU/mL with CBM mean quantum: 96.3 mL and cell counts: 28.1 × 10(3)/μL, CD45(-)/34(+):0.62%, was carried out. Results. All were successfully transplanted without any untoward effect. Over mean followup of 23 months, they had a decreased mean exogenous insulin requirement to 0.63 units/kgBW/day, Hb1Ac to 7.39%, raised serum c-peptide levels to 0.38 ng/mL, and became free of diabetic ketoacidosis events with mean 2.5 Kg weight gain on normal vegetarian diet and physical activities. Conclusion. This is the first report of treating IDDM with insulin-secreting-AD-MSC+CBM safely and effectively with relatively simple techniques.

    Even-numbered dicarboxylic acids (DA) have been proposed as an alternative fuel substrate in parenteral nutrition. In particular, dodecanedioic acid (C12) shows a rapid plasma clearance from tissues, a very low urinary excretion compared with other DA and a high oxidation rate. The aim of the present study was to investigate the effect of C12 infusion on insulin-stimulated glucose uptake in patients with non-insulin-dependent diabetes mellitus (NIDDM) compared with healthy volunteers. A primed-constant infusion of C12 (0.39 mmol/min) was administered over 240 min, and at 120 min a 2 h euglycaemic hyperinsulinaemic clamp was performed. Blood specimens were sampled every 30 min and fractioned urines were collected over 24 h. The levels of C12 were measured by HPLC. Indirect calorimetry was performed continuously during the entire session. Body composition was assessed in all subjects studied to obtain fat-free mass (FFM) values. Whole-body glucose uptake decreased significantly during C12 infusion in both groups, although this effect was much more evident (P < 0.01) in NIDDM patients (52.4 (SD 15.8) % decrease compared with saline) than in controls (25.9 (SD 12.1) % decrease). The M value (mumol/kgFFM per min) was reduced by C12 to lower levels in NIDDM patients than in normal controls (12.6 (SD 3.9) v. 25.9 (SD 4.5), P < 0.01). Urinary excretion of C12 over 24 h was significantly lower in NIDDM patients than in controls (4.26 (SD 0.30) mmol v. 5.43 (SD 0.48), P < 0.01), corresponding to less than 3% of the administered dose. The infusion of C12 decreased non-protein RQ significantly in both groups of patients. In conclusion, this study shows, for the first time, that C12 significantly reduces glucose uptake in both normal controls and NIDDM patients, although this sparing effect on glucose uptake is much more pronounced in diabetic patients. These data suggest that C12 decreases glucose uptake and oxidation, mainly through a mechanism of substrate competition. Thus

    Insulin-dependent diabetes mellitus (IDDM) is an autoimmune endocrinopathy that often develops with anti glutamic acid decarboxylase autoantibody (GAD-Ab). Accumulated data indicate that specific alleles with HLA-DQA1{sup *}0301 strongly associate with IDDM so that its susceptible gene is localized at HLA class II DQ/DR region. The mode of transmission, however, remains still unclear. To investigate the possibility of involvement of genomic imprinting at the susceptible gene in IDDM, we conducted pedigree analysis of 16 IDDM probands who are positive for GAD-Ab and their first-degree relatives consisting of 14 mothers, 11 fathers and 11 sibs. The GAD-Ab was measured with RIA (cut off = 5 U/ml), and genotypes of DQA1 and DRB1 loci were determined with PCR-RFLP method. Of the observed 16 families, one had an affected brother who developed IDDM and was positive for GAD-Ab (144 U/ml), but the remaining 15 were simplex families. Except for the affected brother, all relatives appeared to be negative for GAD-Ab. DQA1 genotyping showed that 11 probands were homozygotes of high-risk DQA1{sup *}0301, but the five probands were heterozygous with DQA1{sup *}0301/X who were informative for the parental origin of DQA1{sup *}0301 allele. Pedigree analyses revealed that all DQA1{sup *}0301 alleles of the five affected heterozygotes were transmitted from their mothers. We next analyzed segregation pattern of DQA1-DRB1 haplotypes and found that the affected brother shared the same maternally transmitted allele with the proband. Further haplotype analysis indicated that the informative six unaffected sibs did not share the maternally transmitted DQA1{sup *}0301 alleles with their probands. From the exclusive association with maternally transmitted DQA{sup *}0301 alleles, we propose the hypothesis that maternal transmission of {open_quotes}affected alleles{close_quotes} are required for the development of IDDM with the mechanism of genomic imprinting at the HLA-DQ/DR region.

    Full Text Available Mucormycosis is one of the most rapidly progressing and lethal form of fungal infections in humans which usually begins in the nose and paranasal sinuses. The fungus assaults the arteries, leading to thrombosis that subsequently causes necrosis of hard and soft tissues. The purpose of this article is to describe a rare case of maxillary necrosis due to mucormycosis in a 12-year-old diabetic patient and emphasizes on early diagnosis and timely management of this potentially fatal fungal infection.

    We examined the activity of the rate-limiting enzyme for hexosamine biosynthesis, glutamine:fructose-6-phosphate amidotransferase (GFA) in human skeletal muscle cultures (HSMC), from 17 nondiabetic control and 13 subjects with non-insulin-dependent diabetes. GFA activity was assayed from HSMC treated with low (5 mM) or high (20 mM) glucose and low (22 pM) or high (30 microM) concentrations of insulin. In control subjects GFA activity decreased with increasing glucose disposal rate (r = -0.68,...

    Previous studies have shown a high prevalence of gastric parietal cell antibodies (PCA) in type 1 diabetes, which can be accompanied by (sub)clinical autoimmune gastric disease. This study aimed to determine the grade of associated autoimmunity and to assess the pattern of prevalence of PCA by gender, age, duration of disease, age at onset of diabetes, and human leukocyte antigen (HLA) type in an adult type 1 diabetic population. Furthermore, to examine the clinical significance of being PCA positive, manifestations of gastric autoimmune disease were studied in PCA-positive and PCA-negative patients. The population studied consisted of 497 type 1 diabetics (men/women, 252/245; mean age, 40.8 +/- 12.1 yr; mean duration of disease, 16.4 +/- 10.4 yr; mean age at onset, 26.9 +/- 13.5 yr; mean hemoglobin A1c, 8.1 +/- 1.6%). Associated autoantibodies were present in 39% and PCA were present in 20.9% of the subjects, particularly in older patients. Gender, duration, and age at onset of diabetes did not influence the appearance of PCA. Antithyroid peroxidase antibodies (aTPO) were more frequent in PCA-positive patients than in those without PCA (33.6% vs. 22.4%; P = 0.025), suggesting an association between gastric and thyroid autoimmunity. We could demonstrate an association between PCA and the HLA DR5 haplotype (P = 0.001) as well, but not with HLA DR3 and/or DR4. In the PCA-positive group, iron deficiency anemia was detected in 15.4%, and pernicious anemia was found in 10.5% of subjects. These autoimmune gastric manifestations were significantly more prevalent in PCA-positive diabetics than in PCA-negative subjects, in whom the percentages were 6.9% and 0.5%, respectively (P = 0.01 and P pernicious anemia. A gastroscopic and anatomopathological examination performed in a subgroup of 30 patients with gastric symptoms revealed atrophic gastritis in 13 of 14 PCA-positive patients and in 9 of 16 PCA-negative subjects (P = 0.04). PCA were present in 59.1% of patients with

    In Latvia diabetes mellitus is diagnosed using the WHO's clinical criteria; assays for the detection of autoantibodies are not available, and hence slowly progressive autoimmune diabetes is likely to be missed. Autoantibodies against glutamic acid decarboxylase (GAD65) and protein tyrosine phosphatase (IA-2) among patients with clinically diagnosed NIDDM identify group of patients with slow-onset type 1 diabetes or LADA. The aim of this study was to estimate the risk of polyendocrine autoimmunity among clinically diagnosed NIDDM patients from Latvia. One hundred NIDDM patients and 100 healthy controls were tested for GAD65 and IA-2 autoantibodies as well as 21-hydroxylase (21-OH) and tissue transglutaminase (TTG) antibodies by RIA assay. Age at onset was >or= 30 years, and duration of disease less than 5 years. Of 100 patients, 85 were on oral hypoglycemic agents and 15 were on insulin. Body mass index (BMI) under 19 was recorded in 1% (1 of 100 cases), while overweight (BMI > 25.5 in females and 27 in males) was documented in 45% (45 of 100 cases). GAD65 antibodies were found in 30 of 100 (30%) and IA-2 antibodies in 40 of 100 (40%) patients. Either GAD65 or IA-2 antibodies were found in 55 of 100 (55%). None of the patients carried antibodies against 21-OH and only 1 of 100 (1%) carried antibodies against TTG. From the results obtained in our study we conclude that in Latvian adult NIDDM subjects, islet autoantibodies identify groups of slow-onset type 1 diabetes but not polyendocrine autoimmunity.

    Common, familial human disorders generally do not follow Mendelian inheritance patterns, presumably because multiple loci are involved in disease susceptibility. One approach to mapping genes for such traits in humans is to first study an analogous form in an animal model, such as mouse, by using inbred strains and backcross experiments. Here the authors describe methodology for analyzing multiple-locus linkage data from such experimental backcrosses, particularly in light of multilocus genetic models, including the effects of epistasis. They illustrate these methods by using data from backcrosses involving nonobese diabetic mouse, which serves as an animal model for human insulin-dependent diabetes mellitus. They show that it is likely that a minimum of nine loci contribute to susceptibility, with strong epistasis effects among these loci. Three of the loci actually confer a protective effect in the homozygote, compared with the heterozygote. Further, they discuss the relevance of these studies for analogous studies of the human form of the trait. Specifically, they show that the magnitude of the gene effect in the experimental backcross is likely to correlate only weakly, at best, with the expected magnitude of effect for a human form, because in humans the gene effect will depend more heavily on disease allele frequencies than on the observed penetrance ratios; such allele frequencies are unpredictable. Hence, the major benefit from animal studies may be a better understanding of the disease process itself, rather than identification of cells through comparison mapping in humans by using regions of homology. 12 refs., 7 tabs.

    Even small increases in the frequency of thrombotic disease in users of OCs have general health impact because of their widespread use, which is currently expanding to potential risk groups. The present investigations were launched to study the effects of OCs containing 20-40 micrograms of EE combined with the latest developed gonane progestogens on biochemical risk markers within metabolic systems involved in the development of arterial thrombotic disease. The studies included evaluation of carbohydrate and lipid metabolism as well as the haemostatic system and were performed in non-diabetic women and in women with IDDM, who are prone to the development of arterial thrombosis. In the evaluation of the carbohydrate metabolism in non-diabetic women, we found no effect on fasting glucose or insulin and no effect on the insulin response to oral glucose in women using monophasic OCs containing EE combined with DSG or GST. This contrasts the evaluation of triphasic OCs containing EE combined with GST or NGT, which increased fasting insulin and reduced insulin sensitivity without affecting the glucose-effectiveness or the beta-cell function. Impaired glucose tolerance developed in 10% of the women after 6 months. These finding suggest that OCs are able to induce a state of insulin resistance, which should be considered in the prescription for women with potential disturbed insulin sensitivity or reduced beta-cell secretory capacity e.g. women with ovarian hyperandrogenism, obesity, previous GDM or perimenopausal women. We found no change in glycaemic control in 22 women with well-regulated IDDM treated with a monophasic combination of EE and GST for one year and none of the women developed microalbuminuria during treatment. In the women with diabetes we observed an increase in fasting levels of triglycerides, a decrease in LDL-cholesterol, and unchanged concentrations of total cholesterol and HDL-cholesterol during treatment. In non-diabetic women treated with the same

    Nine non-insulin-dependent diabetics were studied before and after 3 weeks on an isoenergetic high-fiber/high-starch/low-fat diet (alternative diet), and nine non-insulin-dependent diabetics were studied on their usual diet. In the group that ate the alternative diet, the intake of fiber and starch increased 120% and 53%, whereas fat intake decreased 31%. Diabetes control improved as demonstrated by decreased fasting plasma glucose (P less than 0.05) and 24-hour urinary glucose excretion (P less than 0.05). The in vivo insulin action increased (KIVITT increased, P less than 0.05) with no change in fasting serum insulin levels. In fat cells obtained from patients in the alternative-diet group, insulin receptor binding increased (P less than 0.05) after the change of diet. Insulin binding to purified monocytes (more than 95% monocytes) also increased (P less than 0.05), whereas no change was found in insulin binding to erythrocytes. When lipogenesis was studied at a tracer glucose concentration at which glucose transport seems to be rate limiting, insulin sensitivity increased (P less than 0.02). This is the predicted consequence of increased receptor binding. Moreover, when CO2 production and lipogenesis were studied at a higher glucose concentration, where steps beyond transport seem to be rate limiting for glucose metabolism, increased insulin sensitivity was also observed. In contrast, no change was found in maximal insulin responsiveness. Fat and blood cells from the patients who continued on their usual diet showed no changes of the mentioned quantities.(ABSTRACT TRUNCATED AT 250 WORDS)

    Full Text Available Animal studies have shown that electroacupuncture (EA at Zusanli (ST-36 and Zhongwan (CV-12 acupoints reduces plasma glucose concentrations in rats with type II diabetes. However, whether EA reduces plasma glucose levels in type I diabetes is still unknown. In this study, we explore the various non-insulin-dependent pathways involved in EA-induced lowering of plasma glucose. Streptozotocin (STZ (60 mg kg−1, i.v. was administered via the femoral vein to induce insulin-dependent diabetes in non-adrenalectomized and in adrenalectomomized rats. EA (15 Hz was applied for 30 min to bilateral ST-36 acupoints after administration of Atropine (0.1 mg kg−1 i.p., Eserine (0.01 mg kg−1 i.p., or Hemicholinium-3 (5 μg kg−1 i.p. in non-adrenalectomized rats. Rats administered acetylcholine (0.01 mg kg−1 i.v. did not undergo EA. Adrenalectomized rats underwent EA at bilateral ST-36 acupoints without further treatment. Blood samples were drawn from all rats before and after EA to measure changes in plasma glucose levels. Expression of insulin signaling proteins (IRS1, AKT2 in atropine-exposed rats before and after EA was measured by western blot. Atropine and hemicholinium-3 completely blocked the plasma glucose lowering effects of EA, whereas eserine led to a significant hypoglycemic response. In addition, plasma glucose levels after administration of acetylcholine were significantly lower than the fasting glucose levels. In STZ-adrenalectomized rats, EA did not induce a hypoglycemic response. EA stimulated the expression of IRS1 and AKT2 and atropine treatment blocked the EA-induced expression of those insulin signaling proteins. Taken together, EA at the ST-36 acupoint reduces plasma glucose concentrations by stimulating the cholinergic nerves.

    We examined whether the rise in ketone body concentration around midnight and in the early morning was due to the lack of free insulin (IRI) or excess of insulin counterregulatory hormones such as human growth hormone (hGH), cortisol and glucagon in noninsulin-dependent diabetes mellitus (NIDDM) and insulin-dependent diabetes mellitus (IDDM) patients and whether the monitoring of blood ketone body concentration was clinically useful as an index of metabolic control for deciding to increase or decrease the insulin dose in the treatment of diabetes mellitus. Serum levels of 3-hydroxybutyrate (3-OHBA), acetoacetate (AcAc) and 3-OHBA/AcAc ratio before breakfast were significantly increased in insulin-treated NIDDM patients with well-controlled fasting plasma glucose levels and IDDM patients compared to those in normal subjects. Mirror image diurnal changes were found between serum concentrations of 3-OHBA and serum C-peptide or free IRI in normal subjects and NIDDM patients treated with diet alone or sulfonylurea during the 24-hour daily profiles. However, there were no correlations between 3-OHBA and free IRI in the NIDDM patients treated with insulin and IDDM patients who had a much larger increase in the mean concentration of serum 3-OHBA at 6 a.m. caused by a low concentration of free IRI. Counterregulatory hormones were not increased in IDDM patients compared to normal subjects in the early morning. Cortisol/free IRI and hGH/free IRI molar ratios were significantly increased in NIDDM and IDDM patients compared to normal subjects in the early morning, but glucagon/free IRI molar ratio was not changed between IDDM and normal subjects. In conclusion, the early morning rising of ketone body concentration in insulin-treated diabetic patients, particularly IDDM patients, is due to the absolute lack of free IRI and/or the relative lack of free IRI to the levels of hGH or cortisol, and the monitoring of 3-OHBA is clinically useful as a more sensitive index of metabolic

    Full Text Available Background and Objectives: Diabetes mellitus is among the most common causes of mortality in the world and an important risk factor for chronic kidney disease, foot amputation, ischemic heart disease and blindness among older adults. Diabetic patients mostly develop hyperlipidemia, which can result in cardiovascular diseases. Patient’s knowledge, attitude and practices toward diet are the core center for diabetes control and affect their metabolic control and complications. In the present study, we measured nutritional knowledge, attitude and practices and their relations to serum lipids, HbA1C, and fasting blood glucose in diabetic patients of Boirahmad County, southwest of Iran, where many people encounter increasing prevalence of diabetes. Materials and Methods: 198 IDDM patients from the rural and urban areas of Boirahmad County were invited to the health centers to be checked for their fasting blood glucose, serum total cholesterol, serum HDL cholesterol, serum triglyceride and also serum glycosylated hemoglobin. Their knowledge, attitude, and practices toward the diabetic diet were assessed using a validated questionnaire. The obtained scores were classified into three categories (Poor, average, and Good to show their knowledge, attitude and practice levels, and the serum parameters were compared between the levels to show the relevancies. Results: Our data showed that the patients’ knowledge and attitude on diabetic nutrition are mostly at the average level (79.3% and 47.1%, respectively but their practice scores are mostly at the poor level (43.8%, and just a minor proportion of the patients are at the appropriate levels (15.3, 33, and 23.1% of knowledge, attitude and practices, respectively. In addition, we found a significant reverse relationship between the patients’ nutritional knowledge and  serum HbA1C (p=0.003, and also between their attitude and serum triglyceride (p<0.05. Conclusions: Our data suggest that the knowledge

    Food and Drug Administration (FDA) approved bromocriptine mesylate, a quick release formulation, 0.8 mg tablets, as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus. Bromocriptine products were previously approved by the FDA for the treatment of pituitary tumors and Parkinson's disease. Bromocriptine is thought to act on circadian neuronal activities within the hypothalamus to reset abnormally elevated hypothalamic drive for increased plasma glucose, triglyceride, and free fatty acid levels in fasting and postprandial states in insulin-resistant patients. Adverse events most commonly reported in clinical trials of bromocriptine included nausea, fatigue, vomiting, headache, and dizziness. These events lasted a median of 14 days and were more likely to occur during initial titration of the drug. Due to novel mechanism of action, single daily dose, and lower incidence of stroke, myocardial infarction and vascular events, bromocriptine may act as landmark in treatment of type 2 diabetes.

  8. Sitagliptin reduces cardiac apoptosis, hypertrophy and fibrosis primarily by insulin-dependent mechanisms in experimental type-II diabetes. Potential roles of GLP-1 isoforms.

    Full Text Available BACKGROUND: Myocardial fibrosis is a key process in diabetic cardiomyopathy. However, their underlying mechanisms have not been elucidated, leading to a lack of therapy. The glucagon-like peptide-1 (GLP-1 enhancer, sitagliptin, reduces hyperglycemia but may also trigger direct effects on the heart. METHODS: Goto-Kakizaki (GK rats developed type-II diabetes and received sitagliptin, an anti-hyperglycemic drug (metformin or vehicle (n=10, each. After cardiac structure and function assessment, plasma and left ventricles were isolated for biochemical studies. Cultured cardiomyocytes and fibroblasts were used for in vitro assays. RESULTS: Untreated GK rats exhibited hyperglycemia, hyperlipidemia, plasma GLP-1 decrease, and cardiac cell-death, hypertrophy, fibrosis and prolonged deceleration time. Moreover, cardiac pro-apoptotic/necrotic, hypertrophic and fibrotic factors were up-regulated. Importantly, both sitagliptin and metformin lessened all these parameters. In cultured cardiomyocytes and cardiac fibroblasts, high-concentration of palmitate or glucose induced cell-death, hypertrophy and fibrosis. Interestingly, GLP-1 and its insulinotropic-inactive metabolite, GLP-1(9-36, alleviated these responses. In addition, despite a specific GLP-1 receptor was only detected in cardiomyocytes, GLP-1 isoforms attenuated the pro-fibrotic expression in cardiomyocytes and fibroblasts. In addition, GLP-1 receptor signalling may be linked to PPARδ activation, and metformin may also exhibit anti-apoptotic/necrotic and anti-fibrotic direct effects in cardiac cells. CONCLUSIONS: Sitagliptin, via GLP-1 stabilization, promoted cardioprotection in type-II diabetic hearts primarily by limiting hyperglycemia e hyperlipidemia. However, GLP-1 and GLP-1(9-36 promoted survival and anti-hypertrophic/fibrotic effects on cultured cardiac cells, suggesting cell-autonomous cardioprotective actions.

    It is well known that under the influence of regular, individually measured aerobic physical activity, it is possible to raise the biological efficiency of insulin by several mechanisms: by increasing the number of insulin receptors, their sensitivity and efficiency, as well as by increasing glucose transporters GLUT-4 on the level of cell membrane. The aim of this research was to examine whether decreased insulin resistance could be achieved under the influence of the program of individually measured aerobic physical activity in the 2-week period, in the obese type 2 diabetes patients with the increased aerobic capacity (VO2)max. In 10 type 2 diabetes patients 47.6 +/- 4.6 years of age (group E), in the 14-days period, program of aerobic training was applied (10 sessions--35 min session of walking on treadmill, intensity 60.8 +/- 5.7% (VO2)max, frequency 5 times a week), as well as 1,600 kcal diet. At the same time, other 10 type 2 diabetes patients 45.9 +/- 5.5 years of age (group C) were on 1,600 kcal diet. Before and after this period the following was measured in both groups: insulin sensitivity (M/I) by the method of hyperinsulin euglycemic clamp, and (VO2)max by Astrand test on ergocycle. In contrast to the group C, in the second testing of E group subjects a significant increase was obtained in M/I (1.23 +/- 0.78 vs. 2.42 +/- 0.95 mg/kg/min/mU p VO2)max (26.34 +/- 4.26 vs. 29.16 +/- 5.01 ml/kg/min p tested patients.

    The glucose-lowering effect of vanadate, ammonium metavanadate (AMV), on diabetic KK mice was examined. Five-week-old male KK mice were administrated with a solution of AMV via drinking water at concentrations of vanadium (V) with 0.1, 1.0, 10 and 100 microg/mL for a period of 10 wk, respectively. Body weight, consumption of food and water, and blood glucose levels was measured every week for 10 wk. The results showed that food consumption and body weight in the experimental groups were similar to those in the control group. A statistically significant decrease of drinking water consumption and blood glucose levels in the group treated with 100 microg V/mL was observed. The glucose tolerance in the vanadate-treated mice with 10 and 100 microg V/mL was remarkably improved compared with the control group. Biochemical analyses at the end of experiments demonstrated that a distinct tendency for the glucose and hemoglobin A1c (HbA1c) levels to decrease with vanadate treatment in the blood was also observed. The glutamic pyruvic transaminase, glutamic oxaloacetate transaminase, blood urea nitrogen, triglyceride, high-density lipoprotein, and total cholesterol levels in plasma were lower in the higher vanadium groups than those in the control group. These results indicate that vanadium effectively produced the glucose-lowering effect at a higher dose than that at a low dose of vanadium in drinking water, without any overt signs of toxicity.

    Based on the report that metaiodobenzylguanidine (MIBG) uptake into myocardial sympathetic nerve is useful for evaluation of diabetic heart sympathetic nerve dysfunction, authors examined the effects of epalrestat and vitamin B{sub 12} on the uptake. Subjects giving informed consent were 32 NIDDM patients without hypertensive or ischemic heart diseases on examination by {sup 201}Tl scintigraphy and others. At 10 min and 4 hr after intravenous injection of 111 MBq of {sup 123}I-MIBG, myocardial scintigraphy was performed to obtain the planar images with Siemens ZLC-370 gamma camera, whose data were processed by Shimadzu Scintipack 700 and evaluated by HM=early mean counts in heart (H)/early mean counts in mediastinum (M) and by %WR= (H-M)-(delayed H-delayed M) /(H-M). Epalrestat (150 mg/day) and vitamin B{sub 12} (1.5 mg/day) was given to each 16 patients for 3-5 months and {sup 123}I-MIBG scintigraphy was again carried out to calculate HM and %WR. As results, HM and %WR were not significantly changed by treatment with epalrestat but were improved with vitamin B{sub 12} significantly. (K.H.)

    Urinary glucose excretion reflects the blood glucose levels and is therefore recommended and used as a relevant and practical method for self-control in juvenile diabetes. The purpose of this study was to estimate the attitudes of diabetic children and their parents towards such daily urinalysis. In 1975 69 juvenile diabetics 6--18 years old and their parents were studied and three years later another 69 patients were added. Standardized interviews and questionnaires were used. Only 3 out of 138 patients refused to test their urine regularly and to write down their results in the diary. The results indicate that a great majority of the patients and the parents easily accept the self-testing method and regard it as a valuable tool in the management of the disease. Almost nobody experienced the urine tests as a psychological problem.

    Despite recent interest in the therapeutic potential of recombinant human insulin-like growth factor-I (rhIGF-I) in the treatment of diabetes mellitus, its mechanism of action is still not defined. We have studied the effects of low-dose bolus subcutaneous rhIGF-I (40 microg/kg and 20 microg/kg) on insulin sensitivity, growth hormone (GH) and glucagon levels in seven young adults with insulin-dependent diabetes mellitus (IDDM) using a randomized double-blind placebo-controlled crossover study design. Each was subjected to a euglycemic clamp (5 mmol/L) protocol consisting of a variable-rate insulin infusion clamp (6:00 PM to 8:00 AM) followed by a two-dose hyperinsulinemic clamp (insulin infusion of 0.75 mU x kg(-1) x min(-1) from 8 to 10 AM and 1.5 mU x kg(-1) x min(-1) from 10 AM to 12 noon) incorporating [6,6 2H2]glucose tracer for determination of glucose production/utilization rates. Following rhIGF-I administration, the serum IGF-I level (mean +/- SEM) increased (40 microg/kg, 655 +/- 90 ng/mL, P overnight GH level (40 microg/kg, 9.1 +/- 1.4 mU/L, P = .04; 20 microg/kg, 9.6 +/- 2.0 mU/L, P = .12; placebo, 11.3 +/- 1.7 mU/L) and GH pulse amplitude (40 microg/kg, 18.8 +/- 2.9 mU/L, P = .04; 20 microg/kg, 17.0 +/- 3.4 mU/L, P > .05; placebo, 23.0 +/- 3.7 mU/L) were also reduced. No differences in glucagon, IGF binding protein-1 (IGFBP-1), acetoacetate, or beta-hydroxybutyrate levels were found. During the hyperinsulinemic clamp conditions, no differences in glucose utilization were noted, whereas hepatic glucose production was reduced by rhIGF-I 40 microg/kg (P = .05). Our data demonstrate that in subjects with IDDM, low-dose subcutaneous rhIGF-I leads to a dose-dependent reduction in the insulin level for euglycemia overnight that parallels the decrease in overnight GH levels, but glucagon and IGFBP-1 levels remain unchanged. The decreases in hepatic glucose production during the hyperinsulinemic clamp study observed the following day are likely related to GH

    The purpose of this study was to determine the relationship between changes in maximal oxygen uptake (VO2 max) and submaximal markers of aerobic fitness and changes in risk factors for cardiovascular disease (CVD) and non-insulin-dependent diabetes mellitus (NIDDM) consequent to a 20-week endurance training program. The 502 participants in this study were healthy and previously sedentary men (n = 250) and women (n = 252) of varying age (17 to 65 years) and race (blacks n = 142; whites n = 360) who had completed the HERITAGE Family Study testing and training protocol. Following baseline measurements, participants trained on cycle ergometers 3 days/week for a total of 60 exercise sessions starting at the heart rate (HR) associated with 55% of VO2 max for 30 minutes/session. This was progressively increased to the HR associated with 75% of VO2 max for 50 minutes/session, which was maintained during the last 6 weeks. VO2 max, heart rate at 50 W, power output at 60% of VO2 max, lipids and lipoproteins, resting blood pressure, body composition including abdominal fat (computed tomography [CT] scan), and blood glucose and insulin at rest and at peak following an intravenous glucose tolerance test (IVGTT) were determined both before and after training. Following training, there were significant increases in VO2 max (16%) and the power output at 60% of VO2 max and a significant decrease in HR at 50 W. These changes in markers of aerobic fitness were significantly correlated only to the changes in the body composition variables and the lipids and lipoproteins. Further, there was considerable individual variation in response for all variables studied. Finally, when risk factor data were analyzed by quartile of change in VO2 max, there were few significant relationships. It is concluded that there is a significant relationship between changes in markers of aerobic fitness and changes in several risk factors for CVD and NIDDM. However, the magnitude of these relationships is

  18. Total care for juvenile diabetics--a Swedish experiment.

    Larsson, Y

    1983-01-01

    A Swedish Study Group for Childhood Diabetes has recently prepared a national treatment and care programme for diabetes in children and adolescents, which is briefly presented in this paper. The programme is based on the working hypothesis that long-term vascular and neurological complications - still the most serious threats to the well-being and survival of juvenile diabetics - may be prevented by continuously maintaining a normal or near-normal blood glucose level. Four levels (I--IV) of metabolic control are being defined, of which level I is the optimal goal and level II acceptable, while levels III and IV are regarded as inadequate. To achieve a satisfactory therapeutic result great efforts are required by both patients and the diabetic health teams at the pediatric clinics. In addition to insulin, diet and exercise, great emphasis should be laid on home-monitoring of blood glucose and glycosuria, on patient education and on psychological support both to the children and to their families. The therapeutic team should understand the psychological problems which frequently occur in diabetic families and be able to guide them through the different stages of the disease until the patients reach psychosocial maturity. The programme thus aims at providing a total - biological, functional, emotional and social - care for diabetic children and adolescents, and at thereby improving their quality of life on a long-term basis.

    Urinary glucose excretion reflects the blood glucose levels and is therefore recommended and used as a relevant and practical method for self-control in juvenile diabetes. The purpose of this study was to estimate the attitudes of of diabetic children and their parents towards such daily urinalysis. In 1975 69 juvenile diabetics 6-18 years old and their parents were studied and three years later another 69 patients were added. Still a year later 31 of the children were studied again. Standardized interviews, questionnaires and a special attitude test were used. The results indicate that a great majority of the patients and the parents accept the self-testing method and regard it as a valuable tool in the management of the disease. Almost nobody experienced the urine tests as a psychological problem. As urinalysis has become established as a self-evident part of the treatment, the attitudes have become even more positive among a growing number of patients. Parallel to this feeling of usefulness the patients are honest and the urine tests thus give reliable information.

    Objective To investigate the association between polymorphism ofHLA-DQA1, DQA1 promoter region (QAP) and susceptibility of insulin-dependent diabetes mellitus (IDDM). Methods PCR-RFLP and PCR-SSO gene typing techniques were used to detect HLA-DQA1 alleles and their promoter regions respectively. Results Alleles analysis showed that frequencies of DQA1*0301 and QAP3.2 were significantly increased in the diabetic patients compared to controls (RR=2.80, 2.43, P<0.01), whereas frequencies of DQA1*0601,QAP4.2 were significantly decreased in patients (RR=0.10, P<0.025). The analysis of combinations between promoter and coding gene showed that QAP3.2-DQA1*0301 but not QAP3.1-DQA1*0301 contributes to disease susceptibility, and QAP4.2-DQA1*0601 contributes to protection. Conclusions 1. Susceptibility of IDDM is not restricted to the exon but extends to the promoter region. 2. The same exon linked with different promoters showed different genetic risk for IDDM.%目的 研究胰岛素依赖性糖尿病(IDDM)的易感性与HLA-DQA1及其启动子QAP基因多态性是否存在关联。方法 采用PCR-RFLP分析DQA1等位基因多态性;采用PCR-SSO检测QAP多态性。结果 等位基因分析发现,患者中DQA1*0301、QAP3.2等位基因频率显著高于正常人(RR=2.80、2.43,P<0.01);而DQA1*0601、QAP4.2在患者中分布频率较正常人显著降低(RR=0.10,P<0.025)。启动子与结构基因连锁分析表明:QAP3.2-DQA1*0301单元型与IDDM关联,QAP3.1-DQA1*0301与IDDM无关联;QAP4.2-DQA1*0601则具有保护作用。结论 1.IDDM与HLA的关联不仅存在于结构基因,而且也存在于启动子;2.同一结构基因与不同的启动子连锁可呈现不同的关联格局。

    Full Text Available It is well accepted that insulin-induced hypoglycemia can result in seizures. However, the effects of the seizures, as well as possible treatment strategies, have yet to be elucidated, particularly in juvenile or insulin-dependent diabetes mellitus (IDDM. Here we establish a model of diabetes in young rats, to examine the consequences of severe hypoglycemia in this age group; particularly seizures and mortality. Diabetes was induced in post-weaned 22-day-old Sprague-Dawley rats by streptozotocin (STZ administered intraperitoneally (IP. Insulin IP (15 U/kg, in rats fasted (14-16 hours, induced hypoglycemia, defined as <3.5 mM blood glucose (BG, in 68% of diabetic (STZ and 86% of control rats (CON. Seizures occurred in 86% of STZ and all CON rats that reached hypoglycemic levels with mortality only occurring post-seizure. The fasting BG levels were significantly higher in STZ (12.4 ± 1.3 mM than in CON rodents (6.3 ± 0.3 mM, resulting in earlier onset of hypoglycemia and seizures in the CON group. However, the BG at seizure onset was statistically similar between STZ (1.8 ± 0.2 mM and CON animals (1.6 ± 0.1 mM as well as between those that survived (S+S and those that died (S+M post-seizure. Despite this, the S+M group underwent a significantly greater number of seizure events than the S+S group. 25% glucose administered at seizure onset and repeated with recurrent seizures was not sufficient to mitigate these continued convulsions. Combining glucose with diazepam and phenytoin significantly decreased post-treatment seizures, but not mortality. Intracranial electroencephalograms (EEGs were recorded in 10 CON and 9 STZ animals. Predictive EEG changes were not observed in these animals that underwent seizures. Fluorojade staining revealed damaged cells in non-seizing STZ animals and in STZ and CON animals post-seizure. In summary, this model of hypoglycemia and seizures in juvenile diabetic rats provides a paradigm for further study of

    The reported glucose and immunoreactive insulin (IRI) responses to oral and intravenous glucose in subjects with Type 2 diabetes have not always been consistent. This may have resulted from variations in the method of glucose administration, the ethnic backgrounds of subjects, the diagnostic criteria applied, the duration of the disease or IRI assay methods. The use of a mixed meal rather than glucose has been shown to provide a more physiological stimulus to the pancreatic beta-cell due to both glucose and non-glucose secretagogues. We have analysed the metabolic and hormonal responses of 188 newly diagnosed Caucasian subjects with Type 2 diabetes and 38 non-diabetic subjects to a 500 kcal mixed meal. The diabetic subjects were stratified according to fasting plasma glucose (FPG) ( or = 15 mmol/l) and body mass index (BMI) ( or = 30 kg/m2). Increasing FPG was associated with higher peak glucose concentrations and increasing failure to achieve basal glucose levels by 4 h. Median fasting IRI concentrations were similar to those of normal subjects, but all diabetic subjects had reduced early-phase insulin secretion. Diabetic subjects with FPG 9 mmol/l had progressive falls in IRI AUC to below that of the normal subjects (P < 0.0001 for the trend). Peak IRI concentrations declined progressively with increasing FPG. Despite equivalent glucose exposure simple trends of increasing AUC, IRI with increasing BMI were statistically significant (P < 0.001, P < 0.02, P < 0.001 and P < 0.01, respectively for each FPG group). Both fasting and AUC non-esterified fatty acid concentrations increased significantly with FPG regardless of BMI (P < 0.001 for the trends). These results using a more physiological mixed meal challenge in a large number of recently diagnosed Type 2 diabetic subjects demonstrate a marked and increasing loss of beta-cell secretory function with increasing fasting hyperglycaemia aggravated by insulin resistance with increasing obesity.

    Objective To investigate the clinical effect of individualized exercise therapy on elderly patients with non insulin dependent diabetes mellitus. Methods 46 cases of elderly patients with non-insulin-dependent diabetes mellitus were selected in our hospital from January 2008 to June 2011, who were given individualized exercise therapy on the condition of invariable early treatment. Amount of exercise was equal to the total intake of calories-daily activity burns calo-ries+1128.6 kj. The exercise intensity was 40% to 50% of maximal oxygen consumption. The mode of exercise was 4 times/d walking, the course of treatment was two weeks. Indexes of blood sugar and so on were compared before and after treatment. Results With the exercise intensity increase, maximal oxygen consumption increased significantly, while 2 h postprandial blood glucose level decreased significantly, the differences were statistically significant (P 0.05). All patients had no obvious complications during the period of individualized exercise therapy, while comorbidities also did not deteriorate. Conclusion Individualized exercise therapy can significantly reduce blood glucose level of elderly patients with non-insulin-dependent diabetic mellitus, which is a safe and effective exercise therapy. That is worthy of clinical use.%目的 探讨个体化运动疗法对老年非胰岛素依赖型糖尿病患者的临床疗效.方法 选取本院2008年1月~2011年6月收治的老年非胰岛素依赖型糖尿病患者46例,在前期治疗不变的情况下,给予个体化运动疗法,运动量为总摄入热量-日常活动消耗热量+1 128.6 kJ,运动强度为40%~50%的最大耗氧量,运动方式为4次/d步行,疗程为两周,比较治疗前后患者血糖等指标变化情况.结果随着运动强度的加大,患者最大耗氧量明显增加,餐后2 h血糖水平明显降低,差异有统计学意义(P < 0.05).经个体化运动疗法后患者空腹血糖、餐后2 h血糖、果糖胺、体重指

The severity of retinopathy increased with duration and age of onset of IDDM. Degree of glycaemia (fasting blood sugar, FBS was similar in patients with or without retinopathy. All IDDM patients as a group showed severe carbohydrate intolerance with lower basal and post glucose serum immunoreactive insulin (IRI levels and serum C-peptide radioimmunoreactivity (CPR as compared to controls. The insulin secretory response was similar in no retinopathy, mild retinopathy and severe retinopathy groups. Patients with retinopathy had higher incidence of hyperlipidemia but mean serum levels of cholesterol and triglyceride were similar. This study does not suggest a direct relationship between the various metabolic factors studied and retinopathy due to IDDM

    The detection of subclinical abnormalities in cerebral blood flow could be of great value in identifying diabetic patients at risk of stroke. The aim of this study was to assess the contribution of semiquantified post-acetazolamide technetium-99m hexamethylpropylene amine oxime single-photon emission tomography ({sup 99m}Tc-HMPAO SPET) in 15 diabetic patients with no clinical history of central neurological disease. After baseline {sup 99m}Tc-HMPAO SPET, a second SPET scan was acquired after activation of the cerebrovascular reserve (CVR) with an injection of 1 g of acetazolamide (post-ACZ SPET). Semiquantitative analysis was made in 16 regions of interest (ROIs) drawn for each of the three supratentorial slices selected, and in two ROIs in the infratentorial slice. The CVR was calculated in each ROI by subtracting the decay-corrected baseline images from those obtained in the post-ACZ SPET and expressed as the percent increase in the average counts between the two scans. Baseline perfusion and CVR values in the study group were compared with the corresponding values in a control group. Of 750 cortical ROIs studied, 332 showed a decreased CVR (44.3%). The baseline perfusion SPET study showed hypoperfusion in 65 ROIs (8.6%) and hyperperfusion in 56 (7.4%). Of the 65 hypoperfused regions, 66.2% had a normal CVR and 33.8% had a decreased CVR, whereas of the 56 hyperperfused regions, 51.8% had a CVR within normal limits and 48.2% showed a decreased CVR. In conclusion, in comparison with baseline {sup 99m}Tc-HMPAO SPET, the ACZ activation test provided additional information in the study of cerebrovascular impairment, and allowed characterisation of the subclinical abnormalities in the population studied. The technique may therefore prove useful in evaluating future preventive strategies for stroke in diabetic patients. (orig.)

    Development of type 2 diabetes mellitus and insulin resistance is associated with a quality of dietary fatty acids such as saturated and unsaturated fatty acids. Dietary fatty acids also include transform of unsaturated fatty acids and intake of transform of oleate (elaidate) is associated with cardiovascular disease. However, little is known about the roles of elaidate in insulin responsiveness. We show here that elaidate impairs insulin-dependent glucose uptake in adipocytes. Differentiation with 10 μM elaidate, which is close to physiological plasma concentration, reduces insulin-dependent glucose uptake. Furthermore, insulin-dependent GLUT4 translocation is disturbed in adipocytes differentiated with elaidate. In addition, analysis of lipolysis and gene expression shows that deteriorative effects of elaidate on insulin responsiveness are limited but not general. Thus, our findings reveal that differentiation with elaidate tends to affect insulin-dependent glucose uptake through alternation of GLUT4 translocation from cytosol to the plasma membrane.

    Our previous study indicated that erythrocyte Cu,Zn-superoxide dismutase (Cu,Zn-SOD) undergoes glycation and inactivation in vivo (1) and in vitro (2). The aim of the present study was to assess glycated Cu,Zn-SOD in patients with insulin-dependent diabetes mellitus. Glycated Cu,Zn-SOD, which binds to a boronic acid affinity column, was measured by the enzyme-linked immunosorbent assay. The percentage of the glycated form in 25 insulin-dependent diabetic children was 40.2 +/- 8.2%; this was significantly higher than that in the normal controls (P less than 0.01). The specific activity of the glycated form in the diabetic children was 163,000 +/- 33,000 IU/mg Cu,Zn-SOD protein, significantly lower than that in controls (P less than 0.01). These data indicate that glycated and less active Cu,Zn-SOD is increased in erythrocytes of patients with insulin-dependent diabetes mellitus.

    2008-01-01

    Full Text Available We survey blood glucose control schemes for insulin-dependent diabetes therapies and systems. These schemes largely rely on mathematical models of the insulin-glucose relations, and these models are typically derived in an empirical or fundamental way. In an empirical way, the experimental insulin inputs and resulting blood-glucose outputs are used to generate a mathematical model, which includes a couple of equations approximating a very complex system. On the other hand, the insulin-glucose relation is also explained from the well-known facts of other biological mechanisms. Since these mechanisms are more or less related with each other, a mathematical model of the insulin-glucose system can be derived from these surrounding relations. This kind of method of the mathematical model derivation is called a fundamental method. Along with several mathematical models, researchers develop autonomous systems whether they involve medical devices or not to compensate metabolic disorders and these autonomous systems employ their own control methods. Basically, in insulin-dependent diabetes therapies, control methods are classified into three categories: open-loop, closed-loop, and partially closed-loop controls. The main difference among these methods is how much the systems are open to the outside people.

    Central diabetes insipidus (DI) is well-documented as a presenting feature of myelodysplastic syndrome and acute myeloid leukemia in adults. However, DI is unusual in pediatric patients with myeloid malignancies. We report here this rare complication in a child with neurofibromatosis type 1 who developed juvenile myelomonocytic leukemia and monosomy 7. Our case and previously reported cases of DI arising as a complication in myeloid malignancies demonstrate a close association with deletion of chromosome 7. The clinical characteristics and outcomes of these uncommon cases in children are reviewed and discussed.

    Full Text Available This paper surveys diabetes therapies from telemedicine viewpoint. In type 1 diabetes therapies, the exogenous insulin replacement is generally considered as a primary treatment. However, the complete replacement of exogenous insulin is still a challenging issue because of its complexity of modeling the dynamics, which is typically modeled nonlinearly. On the other hand, thanks to the progress of medical devices, currently the diabetes therapies are being automated. These medical devices include automated insulin pumps and blood glucose sensors. Insulin pumps are designed to create artificial insulin perfusion while they largely rely on the blood glucose profile measurements and these measurements are achieved by one or more blood glucose sensors. The blood glucose measurements are also important for the insulin-dependent diabetes therapies. An insulin pump along with sensors establishes a good feedback system providing the appropriate amount of the exogenous insulin on demand. Controlling the amount of exogenous insulin to suppress the blood glucose levels requires complicated computations. This paper mostly explains both type 1 and 2 diabetes and their mechanisms accompanied by descriptions of diabetes therapy and medical devices currently utilized in the therapy.

    Autophagy is an intracellular defense mechanism responsible for the turnover of damaged or non-functional cellular constituents. This process provides cells with energy and essential compounds under unfavorable environmental conditions-such as oxidative stress and hyperglycemia, which are both observed in diabetes. The most common diabetes complication is diabetic nephropathy (DN), which can lead to renal failure. This condition often includes impaired podocyte function. Here we investigated autophagic activity in rat podocytes cultured with a high insulin concentration (300nM). Autophagy was activated after 60min of insulin stimulation. Moreover, this effect was abolished following pharmacological (apocynin) or genetic (siRNA) inhibition of NAD(P)H oxidase activity, indicating that insulin-dependent autophagy stimulation involved reactive oxygen species (ROS). We also observed a continuous and time-dependent increase of podocyte albumin permeability in response to insulin, and this process was slightly improved by autophagy inhibition following short-term insulin exposure. Our results suggest that insulin may be a factor affecting the development of diabetic nephropathy.

    Full Text Available Introduction:The aim of this work was a quantitative and qualitative assessment of a selected part of the microcirculation in children with diabetes type 1 using videocapillaroscopy technique.Material/Methods:The authors tested a group consisting of 145 children (70 boys, 75 girls diagnosed and treated for diabetes type 1 in the Diabetic Clinic of GCZD in Katowice for at least one year. The study included history, clinical examination (including dermatological examination and videocapillaroscopy. Capillaroscopy, a non-invasive, painless and easily repeatable test, was performed using videocapillaroscopy with digital storage of the obtained images. All nailfolds were examined in all children using videocapillaroscopy, and the obtained images were assessed quantitatively and qualitatively for changes in capillary loops in the tested children according to the defined diagnostic procedure.Results:The analysis of capillaroscopic images described selected quantitative and qualitative characteristics. The conducted analysis showed an increase in the number of capillaries and their elongation, the presence of megacapillaries and Raynaud loops, which were accompanied by an intensive red background, indicating possible neoangiogenesis. The increase in the number of capillaries, disturbances in distribution of capillaries and the presence of abnormal capillaries were correlated with the longer duration of diabetes. Raynaud loops were more frequently found in the cases of increased mean values of HbA1c. Higher values of HbA1c influenced the capillaroscopic images, mainly the number of vessels, including Raynaud loops.Conclusions:Videocapillaroscopy technique could be a useful tool to detect the early changes of microangiopathy in children with diabetes type 1.

    GLUT4 has long been known to be an insulin responsive glucose transporter. Regulation of GLUT4 has been a major focus of research on the cause and prevention of type 2 diabetes. Understanding how insulin signaling alters the intracellular trafficking of GLUT4 as well as understanding the fate of glucose transported into the cell by GLUT4 will be critically important for seeking solutions to the current rise in diabetes and metabolic disease.

    Dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis is often encountered in diabetes, leading to several clinical complications. Our recent results showing an elevated tetrahydrocortisol/tetrahydrocorticosterone ratio in morning urine of diabetic children compared to that of controls suggest an increased nocturnal activity of 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1) in the former. We hypothesized that these observations could be explained by a reduced inhibition of hepatic 11β-HSD1 activity by exogenous insulin owing to its subcutaneous (SC) administration and absence of first hepatic passage. Additionally, we hypothesized that hippocampal 11β-HSD1 activity might also be impaired by diabetes. We therefore measured HPA axis activity and 11β-HSD1 expression and activity in liver and hippocampus in streptozotocin-induced diabetic juvenile rats treated with SC or intraperitoneal (IP) insulin. Plasma corticosterone levels were elevated in untreated diabetic rats during the resting phase and restored by both types of insulin treatment. The mRNA expression and activity of 11β-HSD1 were increased in the untreated diabetic group in liver. Although diabetes was controlled equally whatever the route of insulin administration, liver 11β-HSD1 gene expression and activity was decreased only in the IP group, suggesting that a first hepatic pass is needed for 11β-HSD1 hepatic inhibition. In hippocampus, 11β-HSD1 activity was elevated in the untreated diabetic group but restored by both types of insulin treatment. Thus, these data extend our findings in diabetic children by showing impairment of hippocampal 11β-HSD1 in diabetes and by demonstrating that IP is preferable to SC insulin administration to restore 11β-HSD1 activity in liver.

    Background There is strong evidence suggesting that juvenile idiopathic arthritis (JIA) shares many susceptibility loci with other autoimmune diseases. Objective To investigate variants robustly associated with type 1 diabetes (T1D) or coeliac disease (CD) for association with JIA. Methods Sixteen single-nucleotide polymorphisms (SNPs) already identified as susceptibility loci for T1D/CD were selected for genotyping in patients with JIA (n=1054) and healthy controls (n=3129). Genotype and allele frequencies were compared using the Cochrane–Armitage trend test implemented in PLINK. Results One SNP in the LPP gene, rs1464510, showed significant association with JIA (ptrend=0.002, OR=1.18, 95% CI 1.06 to 1.30). A second SNP, rs653178 in ATXN2, also showed nominal evidence for association with JIA (ptrend=0.02, OR=1.13, 95% CI 1.02 to 1.25). The SNP, rs17810546, in IL12A showed subtype-specific association with enthesitis-related arthritis (ERA) subtype (ptrend=0.005, OR=1.88, 95% CI 1.2 to 2.94). Conclusions Evidence for a novel JIA susceptibility locus, LPP, is presented. Association at the SH2B3/ATXN2 locus, previously reported to be associated with JIA in a US series, also supports this region as contributing to JIA susceptibility. In addition, a subtype-specific association of IL12A with ERA is identified. All findings will require validation in independent JIA cohorts. PMID:20647273

    Full Text Available In the present study, we have decided to evaluate if serum transforming growth factor-beta 1 (TGF-β1 concentrations may have diagnostic value in predicting the occurrence of diabetic retinopathy (DR in juvenile patients with type 1 diabetes mellitus (T1DM. The study included 81 children and adolescents with T1DM and 19 control subjects. All study participants had biochemical parameters examined, underwent an eye examination, and 24-hour blood pressure monitoring. Moreover, serum concentrations of TGF-β1 were measured. The group of patients with T1DM and nonproliferative diabetic retinopathy (NPDR had statistically significant higher serum levels of TGF-β1 (P=0.001 as compared to T1DM patients without retinopathy as well as the healthy control subject. The threshold serum TGF-β1 concentrations which had a discriminative ability to predict the presence of DR were calculated using the receiver operating characteristic (ROC curves analysis and amounted to 443 pg/ml. The area under the ROC curve (AUCROC was 0.80, and its population value was in the range of 0.66 to 0.94. The sensitivity and specificity were calculated to be 72% and 88%, respectively. Our results suggest that TGF-β1 serum concentrations may be an additional parameter in predicting the occurrence of DR in juvenile patients with T1DM.

    To determine whether women with a history of juvenile arthritis are at higher risk for heart disease and hypertension and for developing adverse maternal outcomes: gestational diabetes mellitus, maternal hypertension, and preeclampsia/eclampsia. We designed a nested case-control study from a cohort of first-time mothers with prior physician billing codes suggesting juvenile arthritis, and a matched comparison group without juvenile arthritis. For the nested case-control design, we selected 3 controls for each case for the outcomes of heart disease (n = 403), prepregnancy hypertension (n = 66), gestational diabetes mellitus (n = 285), maternal hypertension (n = 561), and preeclampsia/eclampsia (n = 236). We used conditional logistic regression, adjusting for maternal age and education. Having juvenile arthritis was associated with heart disease (odds ratio [OR] 2.44 [95% confidence interval (95% CI) 1.15-5.15]) but not with gestational hypertension, diabetes mellitus, or preeclampsia/eclampsia. All 66 cases of prepregnancy hypertension had juvenile arthritis. Having prepregnancy hypertension was strongly associated with preeclampsia/eclampsia (OR 8.05 [95% CI 2.69-24.07]). Women with a history of juvenile arthritis had a higher risk of heart disease. This risk signals the potential importance of cardiac prevention strategies in juvenile arthritis. As this was a retrospective study, it was not possible to correct for some relevant potential confounders. Further studies should assess the impact of medications, disease severity, and other factors (e.g., obesity) on cardiac outcomes in juvenile arthritis. © 2016, American College of Rheumatology.

    Full Text Available The sensing of ribonucleic acids (RNAs by the monocyte/macrophage system occurs through the TLR7/8 Toll-like receptor family, the retinoic acidi–nducible protein I (RIG-I, and the melanoma differentiation–associated protein-5 (MDA-5. The aim of the present study was to evaluate the effect of circulating RNAs, isolated from juvenile type 1 diabetic patients and healthy control children, on the inflammatory, apoptotic, and antiviral response in human peripheral blood mononuclear cells (PBMCs isolated from a healthy donor. Obtained effects were compared to the effects of metabolic stress parameters (hyperglycemia, oxidative and nitrosative stress. Forty-eight patients with juvenile type 1 diabetes and control children were included in the study. By performing the chromatographic analysis of circulating RNAs, the peak at the retention time 0.645 min for diabetic and control RNA samples was identified. To determine whether circulating RNAs have an agonistic or antagonistic effect on the signaling pathways involved in inflammatory, apoptotic, and antiviral cascade, their effect on TLR8, RIG-I, MDA-5, MyD88, NF-κB, IRF-3, phosphoIRF-3, IRF-7, RIP, and p38 was evaluated. A significantly lower level was achieved by cultivating PBMCs with circulating RNAs isolated from type 1 diabetic children, compared to the intact PBMCs, in relation to TLR-8, MDA-5, NF-κB, phospho IRF-3, and RIP, while it was higher for Bax. All the metabolic stress conditions up-regulated NF-κB, Bcl-2, and Bax. The NF-κB, determination seems to be the most sensitive parameter that may reflect disease processes associated with the progression of autoimmune or inflammatory conditions, while the IRF3/phosphoIRF3 ratio may suggest an insufficient antiviral response.

    Serotonin (5-HT) and histamine metabolism was studied in 50 patients with diabetes melitus. Simultaneously the blood and urine content of their precursors and metabolites tryptophane, 5-hydroxytryptophane (5-HTP), 5-hydroxyindolylacetic acid (5-HIAA) and histidine was examined. An increase in 5-HT metabolism intensification (the augmented 5-HTP and 5-HT blood levels and enhanced 5-HTP and 5-HIAA excretion with the urine) was determined, whereas the blood and urine contents of histamine and histadine were within normal. Moreover, significantly higher increase in 5-HT blood level and enhanced 5-HIAA excretion with the urine were seen in patients with juvenile diabetes mellitus comparatively to those with insulin-depending type of the disease. Possible significance of changes, being discovered in 5-HT metabolism of patients with diabetes mellitus, in the disease pathogenesis is discussed.

    The prevalence of overweight (body mass index, BMI, between 25 and 30 kg/m2) and obesity (BMI of 30 kg/m2 or higher) is increasing rapidly worldwide, especially in developing countries and countries undergoing economic transition to a market economy. One consequence of obesity is an increased risk of developing type II diabetes. Overall, there is considerable evidence that overweight and obesity are associated with risk for some of the most common cancers. There is convincing evidence of a positive association between overweight/obesity and risk for adenocarcinoma of the oesophagus and the gastric cardia, colorectal cancer, postmenopausal breast cancer, endometrial cancer and kidney cancer (renal-cell). Premenopausal breast cancer seems to be inversely related to obesity. For all other cancer sites the evidence of an association between overweight/obesity and cancer is inadequate, although there are studies suggesting an increased risk of cancers of the liver, gallbladder, pancreas, thyroid gland and in lymphoid and haematopoietic tissue. Far less is known about the association between diabetes mellitus type I (also called insulin dependent diabetes mellitus or juvenile diabetes), type II diabetes (called non-insulin dependent diabetes mellitus or adult onset diabetes mellitus) and cancer risk. The most common type of diabetes mellitus, type II, seems to be associated with liver and pancreas cancer and probably with colorectal cancer. Some studies suggest an association with endometrial and postmenopausal breast cancer. Studies reporting on the association between type I diabetes mellitus, which is relatively rare in most populations and cancer risk are scanty, but suggest a possible association with endometrial cancer. Overweight and obesity, as well as type II diabetes mellitus are largely preventable through changes in lifestyle. The fundamental causes of the obesity epidemic-and consequently the diabetes type II epidemic-are societal, resulting from an

    Elmo2, a member of the Elmo protein family, has been implicated in the regulation of Rac1 and Akt activation. Recently, we found that Elmo2 specifically interacts with ClipR-59. Because Akt and Rac1 have been implicated in insulin dependent Glut4 membrane translocation, we hypothesize here that Elmo2 may play a role in insulin-dependent Glut4 membrane translocation. Accordingly, we found that overexpression of Elmo2 enhanced, whereas its knockdown suppressed, insulin-dependent Glut4 membrane translocation in both 3T3-L1 adipocytes and L6 skeletal muscle cells. We also examined whether Elmo2 contributes to the insulin-mediated activation of Rac1 and Akt. We found that Elmo2 is required for insulin-induced Rac1 GTP loading, but not AKT activation, in L6 cells induced by insulin. Instead, Elmo2 is required to promote the insulin-induced membrane association of Akt. Together, our studies demonstrate that Elmo2 is a new regulator of insulin-dependent Glut4 membrane translocation through modulating Rac1 activity and Akt membrane compartmentalization.

    Type 1 diabetes (T1D) is a chronic disease caused by autoimmune destruction of insulin-producing pancreatic β-cells. T1D is typically diagnosed in children, but information regarding immune cell subsets in juveniles with T1D is scarce. Therefore, we studied various lymphocytic populations found in the peripheral blood of juveniles with T1D compared to age-matched controls (ages 2-17). One population of interest is the CD28(-) CD8(+) T cell subset, which are late-differentiated cells also described as suppressors. These cells are altered in a number of disease states and have been shown to be reduced in adults with T1D. We found that the proportion of CD28(-) cells within the CD8(+) T cell population is significantly reduced in juvenile type 1 diabetics. Furthermore, this reduction is not correlated with age in T1D juveniles, although a significant negative correlation between proportion CD28(-) CD8(+) T cells and age was observed in the healthy controls. Finally, correlation analysis revealed a significant and negative correlation between the proportion of CD28(-) CD8(+) T cells and T1D disease duration. These findings show that the CD28(-) CD8(+) T cell population is perturbed following onset of disease and may prove to be a valuable marker for monitoring the progression of T1D.

    Background: Obesity among pregnant women is common, and their offspring are predisposed to obesity, insulin resistance, and diabetes. The circulating metabolites that are related to insulin resistance and are associated with this decreased tissue-specific uptake are unknown. Here, we assessed metabolite profiles in elderly women who were either female offspring from obese mothers (OOM) or offspring of lean mothers (OLM). Metabolic changes were tested for associations with metrics for insulin resistance. Methods: Thirty-seven elderly women were separated into elderly offspring from obese mothers (OOM; n = 17) and elderly offspring from lean/normal weight mothers (OLM; n = 20) groups. We measured plasma metabolites using proton nuclear magnetic resonance (1H-NMR) and insulin-dependent tissue-specific glucose uptake in skeletal muscle was assessed. Associations were made between metabolites and glucose uptake. Results: Compared to the OLM group, we found that the docosahexaenoic acid percentage of the total long-chain n-3 fatty acids (DHA/FA) was significantly lower in OOM (p = 0.015). DHA/FA associated significantly with skeletal muscle glucose uptake (GU) (p = 0.031) and the metabolizable glucose value derived from hyperinsulinemic-euglycemic clamp technique (M-value) in the OLM group only (p = 0.050). Conclusions: DHA/FA is associated with insulin-dependent skeletal muscle glucose uptake and this association is significantly weakened in the offspring of obese mothers. PMID:28165405

    The present study was undertaken to examine the feasibility of determining the most appropriate subcutaneous insulin treatment in unstable diabetes on the basis of the circadian hormonal profile delivered by an artificial pancreas. The metabolic control of 11 brittle diabetic subjects, as assessed by the M value and the MAGE index (used as indexes of blood glucose control and of glycemic fluctuations, respectively), was compared during a 5-day period before and after a 24-h connection to the artificial pancreas. The usual insulin treatment was continued to that day. Examination of the insulin pattern revealed by the artificial pancreas suggested that a valid scheme for subsequent treatment should consist of two daily injections of a mixture of short-acting and intermediate-acting insulins, which was administered to the patients beginning with the injection given after the artificial pancreas onwards. The new insulin regimen was characterized by a total daily dose that increased from 0.93 +/- 0.10 to 1.20 +/- 0.10 U/kg body weight (mean +/- SEM; P less than 0.005) as well as by a higher proportion of the dose given as regular insulin (37.1 +/- 6.9% before vs. 56.0 +/- 2.1% after; P less than 0.05). These changes led to a better control of blood glucose in 10 patients, as evidenced by a decrease of both the M value and the mean of all blood glucose levels. The mean MAGE index was not decreased, however, by the new insulin program, thereby suggesting that the lability of the disease remained unabated. These results indicate that subcutaneous treatment consisting of two daily injections of regular and intermediate-acting insulins and comprising 50 to 60% of the former could improve the metabolic control in unstable diabetes. The artifical pancreas provided a rapid and simple means to determine the appropriate doses for each type of insulin.

  17. [Glutamate decarboxylase (GAD)--an autoantigen in insulin-dependent diabetes mellitus (IDDM)].

    1999-02-01

    The number of antibodies to pancreatic beta-cell antigens in IDDM increased in the last years, involving antibodies to glutamic acid decarboxylase (GADab). A short review is given about the diagnostic and prognostic value of GADab determination in IDDM. The GAD plays an important, possibly a key role in the initial immunological events leading to the destruction of beta cells. The question is open whether the immunological reaction against GAD is a primary one, or if it is a result of mimicry of a part of an infectious protein antigen (Coxackie virus). The immunological reaction to GAD is associated with both humoral and cellular responses. The cellular response seems to be more important than the humoral one. The cellular response may be mediated through the HLA complex class I cells (cytotoxic lymphocytes) and the HLA complex class II cells (helper lymphocytes). There are arguments for both possibilities. The principles of GADab determination are shortly described. (Ref. 34.)

Sensory and motor nerve conduction and distal motor latency in the ulnar nerve were determined before, immediately after induction of hyperglycemia, and again after 120 min hyperglycemia. Distal (5th finger - wrist......) and proximal (wrist - elbow) sensory nerve conduction showed an insignificant increase as hyperglycemia was induced. During hyperglycemia mean distal sensory conduction decreased from 53.1 m/s to 50.4 m/s (P less than 0.05) and mean proximal sensory conduction decreased from 56.0 m/s to 54.2 m/s (P less than 0.......01). A mean of distal and proximal sensory conduction increased (53.5 m/s vs 54.6 m/s) (P less than 0.05) as hyperglycemia was induced and decreased (54.6 m/s vs 52.3 m/s) (P less than 0.01) during clamping.

    An immunoprecipitation assay for autoantibodies (Abs) to the human islet cell antigen IA-2 has been developed using 125I-labelled recombinant IA-2 expressed in E. coli. With this assay IA-2 Abs were detected in 103/217 (47%) of IDDM patients of different ages and with different disease duration. IA-2 Ab prevalence was higher in younger patients (at the age of 15 years or below) with the recent onset IDDM (64/113; 57%) compared to patients above the age of 15 years (11/25; 44%). One of 40 (2.5%) Graves' disease patients and five of 204 (2.5%) of NIDDM patients were also positive. IA-2 Abs were not detected in sera from patients with Hashimoto's thyroiditis (n=32), myasthenia gravis (n=20) or systemic lupus erythematosus (n=10). IA-2 Ab measurements based on 125I-labelled IA-2 showed a good correlation with the results of an immunoprecipitation assay based on 35S-labelled IA-2 produced in the in vitro transcription/translation system (r=0.78; n=113; pAb testing in IDDM. Overall, the IA-2 Ab assay based on 125I-labelled recombinant IA-2 showed good sensitivity, precision and specificity which, combined with an easy and convenient protocol, makes it attractive for routine use.

    Full Text Available Diabetes mellitus type 1 is associated with an enhanced apoptosis of different cells and tissues, accelerating occurrence of diabetic microvascular complications. The aim of our study was to determine spontaneous apoptotic potential of the monocyte subsets in juvenile-onset complication-free diabetes mellitus type 1 and to compare them with the corresponding values of the healthy. Moreover, we wanted to assess effects of TNF-R1 blocking agents and those of general TNF-α blocker (Infliximab on spontaneous apoptosis of monocytes. Sixty randomly selected DM1 patients (14.5 ± 3.2 years and 30 healthy (13.5 ± 2.8 years volunteers were enrolled in the study. Our results indicate that three monocyte subsets are distinguishable in the groups of young diabetic patients and the healthy, similarly to in the blood of adults. DM1 patients were characterized by higher values of apoptotic monocytes than the healthy. The manipulation with drugs inhibiting TNF-R1 expression diminished the pool of CD16+ apoptotic monocytes. Infliximab reduced the apoptotic CD16− cells. In conclusion, diabetes mellitus type 1 is associated with greater apoptosis of three monocyte subsets which may contribute to the development of microvascular complications. TNF-α modifiers appear to ameliorate monocyte apoptosis. They may be useful for controlling excessive monocyte apoptosis in diabetic patients.

    1992-10-01

    The altered excretion of isoenzymes of amylase in urine was used as an early indicator of the loss of electric charges in the glomerular basement membrane, in 202 juvenile-onset insulin-dependent diabetic patients, compared with the pattern of excretion in 51 normal subjects matched for age and sex. Diabetics showed an increased excretion of salivary amylase. The salivary to pancreatic amylase ratio in urine (S/P ratio) was always below 1 in control subjects, but was elevated in 33.2% of diabetics, although microalbuminuria was present in only 26.2% of diabetic patients. The concentrations of other proteins in urine were within the reference ranges in nearly all patients, indicating that the kidney was not seriously affected. The increased salivary amylase excretion was not due to changes in the plasma concentration of any of the isoamylases, but to a real increase in excretion, as its fractional excretion in relation to creatinine clearance was clearly increased (1.0 +/- 0.7 vs. 1.52 +/- 1.99, p ratio of their clearances was also increased (0.35 +/- 0.18 vs. 0.49 +/- 0.61, p > 0.05). Moreover, the prevalence of altered S/P ratios was higher than the prevalence of microalbuminuria (36.6% vs. 18.8% of patients in the first decade of evolution of insulin-dependent diabetes mellitus). Altered S/P ratios were most prevalent in the first decade, whereas microalbuminuria was most prevalent in the second decade of the disease.(ABSTRACT TRUNCATED AT 250 WORDS)

    [Purpose] The purpose of this study was to investigate the effects of 12 weeks regular aerobic exercise on brain-derived neurotrophic factor (BDNF) and inflammatory factors in juvenile obesity and type 2 diabetes mellitus (T2DM). Obesity and T2DM, typically common among adults, have recently become more prevalent in the Korean juvenile population, affecting not only their lipid profiles and oxidant stress levels, but also their BDNF and inflammatory factor levels. [Subjects] This study enrolled 26 juveniles (boys = 15, girls = 9) who were assigned to a control group (CG, n = 11), obesity group (OG, n = 8), or T2DM group (TG, n = 7). [Methods] The outcome of a 40–60-minute aerobic exercise session that took place three times per week for 12 weeks at a maximum oxygen intake (VO2max) of 50~60% was investigated. [Results] The exercise resulted in a significant reduction in the resting serum BDNF and TrkB levels (baseline) among juveniles in the OG and TG as compared to those in the CG. Additionally, the 12 weeks of regular aerobic exercise led to significant reductions in body weight, body fat percentage, and body mass index in the OG and a significant increase of VO2max in the OG and TG. However, no significant differences in serum NGF or inflammatory factors were found among the three groups. There was a significant increase in resting serum BDNF levels following the 12 weeks regular exercise only in the OG. [Conclusion] While 12 weeks of regular aerobic exercise had a positive effect on body composition, and increased BDNF levels of juveniles in the OG, it did not affect the inflammatory factor levels and had no effect on the TG.

    The insulin, to provide with energy the biological function of locomotion, formed: a) pool of phylogenetically late insulin-dependent cells; b) highly productive vector variant of transfer of saturated and mono unsaturated fatty acids only to insulin-dependent cells; c) new variant of active absorption of substrates for acquiring energy by cells--apoE/B-100-receptor endocytosis; d) transformation of all endogenically synthesized palmitic saturated fatty acid in oleic mono saturated fatty acid and e) replacement of potentially ineffective palmitic variant of formation of energy in vivo with potentially high-performance oleic variant of metabolism of substrates for turning out of ATP. The insulin expressed synthesis of apoE glucose carrier 4 and stearyl-KoA-desaturase. These occurrences confirm that syndrome of insulin resistance primarily is the pathology of metabolism of fatty acids and only secondary the pathology metabolism of glucose. The multi-functional fatty cells of visceral areolar tissue and specialized adipocytes of subcutaneous fat depots are phylogenetically, regulatory and functionally different cells. They are formed under development of different biological functions: the first ones under realization of biological function of trophology and second ones under realization of biological function of locomotion. At the level of organism, the mechanisms of hypothalamus-fatty cells feedback are realized by peptide leptin and in case of hypothalamus-adipocytes feedback--peptide adiponectin. The potential possibilities of mitochondria in synthesis of ATP are high and are conditioned only by amount of substrate of mitochondria acetyl-KoA. This shortage can be chronic as in cases of disorder of insulin function and palmitic variant of metabolism of substrates for acquiring energy by cells. The deficiency of acetyl-KoA can be acute as is the case of diabetic coma when surplus amount of ketonic bodies follows the expressed deficiency of acetyl-KoA formed from

    Melanin-concentrating-hormone (MCH)-expressing neurons (MCH neurons) in the lateral hypothalamus (LH) are critical regulators of energy and glucose homeostasis. Here, we demonstrate that insulin increases the excitability of these neurons in control mice. In vivo, insulin promotes phosphatidylinositol 3-kinase (PI3K) signaling in MCH neurons, and cell-type-specific deletion of the insulin receptor (IR) abrogates this response. While lean mice lacking the IR in MCH neurons (IR(ΔMCH)) exhibit no detectable metabolic phenotype under normal diet feeding, they present with improved locomotor activity and insulin sensitivity under high-fat-diet-fed, obese conditions. Similarly, obesity promotes PI3 kinase signaling in these neurons, and this response is abrogated in IR(ΔMCH) mice. In turn, acute chemogenetic activation of MCH neurons impairs locomotor activity but not insulin sensitivity. Collectively, our experiments reveal an insulin-dependent activation of MCH neurons in obesity, which contributes via distinct mechanisms to the manifestation of impaired locomotor activity and insulin resistance.

    Nonautoimmune ketosis-prone diabetic syndromes are increasingly frequent in nonwhite populations. We have characterized a cohort of patients of sub-Saharan African origin who had ketosis-prone type 2 diabetes (n = 111), type 1 diabetes (n = 21), and type 2 diabetes (n = 88) and were admitted to a hospital for management of uncontrolled diabetes. We compared epidemiological, clinical, and metabolic features at diabetes onset and measured insulin secretion (glucagon-stimulated C-peptide) and insulin action (short intravenous insulin tolerance test) during a 10-year follow-up. Ketosis-prone type 2 diabetes shows a strong male predominance, stronger family history, higher age and BMI, and more severe metabolic decompensation than type 1 diabetes. In ketosis-prone type 2 diabetes, discontinuation of insulin therapy with development of remission of insulin dependence is achieved in 76% of patients (non-insulin dependent), whereas only 24% of patients remain insulin dependent. During evolution, ketosis-prone type 2 diabetes exhibit specific beta-cell dysfunction features that distinguish it from type 1 and type 2 diabetes. The clinical course of non-insulin-dependent ketosis-prone type 2 diabetes is characterized by ketotic relapses followed or not by a new remission. Progressive hyperglycemia precedes and is a strong risk factor for ketotic relapses (hazard ratio 38). The probability for non-insulin-dependent ketosis-prone type 2 diabetes to relapse is 90% within 10 years, of whom approximately 50% will become definitively insulin dependent. Insulin sensitivity is decreased in equal proportion in both ketosis-prone type 2 diabetes and type 2 diabetes, but improves significantly in non-insulin-dependent ketosis-prone type 2 diabetes, only after correction of hyperglycemia. In conclusion, ketosis-prone type 2 diabetes can be distinguished from type 1 diabetes and classical type 2 diabetes by specific features of clinical pathophysiology and also by the natural history of

    The results of the study of morphological and biophysical parameters of the cell membrane of live lymphocytes in patients with insulin-dependent and non-insulin dependent diabetes mellitus and healthy donors using atomic force microscopy have been presented. It is found that lymphocytes from patients with diabetes are characterized by a decrease in volume and cell surface roughness compared to normal lymphocytes. An increase in the Young's modulus of lymphocytes in patients with diabetes more than 3 times compared to normal rates has been shown. Increased stiffening of lymphocyte cytolemma in patients with non-insulin dependent diabetes mellitus leads to a decrease in its adhesive properties, unlike lymphocytes in patients with insulin-dependent diabetes mellitus.

    Full Text Available Rare genetic or inherited forms of diabetes can mimic immune mediated type 1 diabetes. Early age of onset and associated features help to differentiate these diseases from type 1 diabetes. Wolfram syndrome, an inherited neuro degenerative disorder, presents as insulin dependent diabetes mellitus, diabetes insipidus, optic atrophy and deafness. But less well described features like psychiatric manifestations can be the presentation of this disease. We present such a case. Wolfram syndrome should be considered as a differential diagnosis in insulin dependent diabetic children who present with neuropsychiatric problems.

    Juvenile scleroderma is a rare childhood condition characterized by fibrosis of the skin and internal organs. Clinical manifestations of childhood scleroderma are different from adult disease and early recognition, correct classification and treatment can improve long-term outcome. This review explores the most recent actualizations on clinical manifestations, classification criteria, treatment options and prognosis of juvenile scleroderma. There are two main forms of the disease: localized scleroderma and systemic sclerosis. Localized scleroderma is the most common form in children and mostly restricted to the skin. Juvenile diffuse systemic sclerosis is related to visceral involvement and cardiac disease which is the main cause of death in these patients. The outcome of juvenile systemic sclerosis is better compared with the adult form. Treatment remains a medical challenge and the EULAR task force proposed an approach to juvenile scleroderma treatment based on expert's opinion and guidelines used for the treatment of adults. Larger studies on childhood scleroderma are warranted.

    The haem pathway is impaired in porphyrias and a frequent coexistence of diabetes mellitus and porphyria disease has been reported. We have therefore decided to investigate delta-aminolevulinate dehydratase, one of the more sensitive enzymes in the haem pathway, in both human diabetic patients and diabetic rats. We have studied 131 diabetes mellitus patients, 32 insulin dependent and 99 non-insulin dependent. The latter group was further subdivided according to treatment: diet alone (n = 24), diet plus oral hypoglycemic agents (n = 28) and diet plus insulin (n = 47). We have also performed similar studies in the rat model of diabetes mellitus, induced in 11 Wistar rats by streptozotocin. Control groups of both humans and animals were used. Erythrocytic aminolevulinate dehydratase activity was reduced in both insulin dependent and non-insulin dependent diabetic patients as compared to their controls (p glycosilated hemoglobin concentration (p < 0.05) and in non-insulin dependent diabetes mellitus to the glycemia (p < 0.01). In the diabetic rat, aminolevulinate dehydratase activity was diminished on both erythrocytes (p < 0.01) and hepatic tissue (p < 0.01) when compared to the control group. The decrease in activity of erythrocyte aminolevulinate dehydratase observed in diabetic patients, may represent an additional and useful parameter for the assessment of the severity of carbohydrate metabolism impairment.

    2014-01-01

    Full Text Available Introduction: Zinc transporter-8 (ZnT8 is an islet cell secretory granule membrane protein recently identified as an autoantigen in type 1 diabetes (T1D. The aim of this study was to estimate the prevalence of antibodies to ZnT8 (ZnT8A in juvenile onset T1D and to determine the utility of ZnT8A as an independent marker of autoimmunity either alone in antibody-negative subjects or in conjunction with glutamic acid decarboxylase (GAD and insulinoma-2 antigen antibodies (GADA and IA2A. Research Design: ZnT8A, GADA, and IA2A were measured in sera of consecutive T1D patients (n = 88, age range 2-18 years within 4 years of diagnosis and 88 sex-matched controls. Results: The prevalences of GADA, ZnT8a, and IA2A were 64.7%, 31.8% and 19.3%, respectively. In newly diagnosed patients, the frequency of ZnT8A was 45%. ZnT8A were positive in 26% of patients negative for both GADA and IA2A. IA2A were positive only in two patients who were negative for other two antibodies. Combined use of ZnT8A and GADA could detect 97% of antibody positive patients. In receiver operating characteristic (ROC analysis, the performances of GADA and ZnT8As were better than that of IA2A; and AUCs of GADA, ZnT8A, and IA2A for the prediction of T1D were 0.8, 0.65, and 0.59, respectively. Conclusions: ZnT8A complements GADA and increases the diagnostic sensitivity for detection of autoimmunity in juvenile-onset T1D. Inclusion of ZnT8A increases the proportion of patients with antibody positivity to nearly 80%. ZnT8A can replace IA2A as a serological marker for autoimmunity in Indian T1D patients without loss of sensitivity and specificity.

    Full Text Available Diabetes mellitus is a metabolic abnormality in which there is a failure to utilise glucose and hence a state of hyperglycaemia can occur. If hyperglycaemia continues uncontrolled over time, it will lead to significant and widespread pathological changes, including involvement of the retina, brain and kidney.In industrialised countries, approximately 1% of the population is diabetic, and at least another 1% are undiagnosed diabetics. Insulin dependent diabetes (IDDM, accounts for approximately 10-15% of cases, the remainder being maturity onset or non-insulin dependent diabetics (NIDDM. Diabetes mellitus is an international public health problem with estimated prevalences ranging from 2.0% to 11.7% in studied populations across the world.

  1. Drug therapy for diabetes.

    Haas, L B

    Drug therapy with oral hypoglycemic agents and insulin are components of diabetes management regimens that also include diet, exercise/activity, monitoring, and education. Major concerns for practitioners using drug therapy are selection of the appropriate therapy for a particular patient, and drug interactions and side effects. Drug therapy is based on knowledge of the medications' pharmacokinetics; glucose goals, as determined by practitioners and patients; common sense; and strong participatory relationships between practitioners and patients and, if indicated, families. When using insulin, practitioners need to consider the differences between insulin therapy for insulin-dependent and non-insulin-dependent diabetes; how to initiate, adjust, and supplement insulin; situations that require variations in insulin therapy; and injection mechanics.

    2011-01-01

    Full Text Available Introduction. Juvenile myasthenia is a chronic autoimmune neuromuscular disease characterized by varying degrees of fluctuating, painless muscle weakness and rapid fatigue of any muscles under voluntary control. Juvenile myasthenia is a form of myasthenia appearing in adolescent age, representing 10% to 15% of all cases of myasthenia gravis. Juvenile myasthenia is presented by a defect in the transmission of nerve impulses to muscles, resulting from a breakdown in the normal communication between nerves and muscles. In myasthenia, antibodies produced by the body’s own immune system block, alter, or destroy the receptors for acetylcholine. Juvenile myasthenia is neither directly inherited nor is it contagious. Signs and Symptoms. The first noticeable symptoms may be eye muscle weakness, difficulty in swallowing, or slurred speech. Juvenile myasthenia usually affects muscles innervated by the cranial nerves (face, lips, tongue, neck and throat, but it can affect any muscle group. Symptoms vary in type and severity with typical periods of exacerbation interspersed with periods of remission. When the muscles necessary for breathing are affected, a patient is said to be in a myasthenic crisis, which is a life-threatening situation. Disease Outcome and Treatment. Juvenile myasthenia produces sporadic but progressive weakness and abnormal fatigability of striated (skeletal muscles, exacerbated by exercise and repeated movement, but improved by rest and anticholinesterase drugs. Juvenile myasthenia follows an unpredictable course of recurring exacerbations and periodic remissions. With current therapies, however, most cases of juvenile myasthenia are not as serious as the name implies. Although there is no known cure, drug treatment has improved prognosis and allows patients to lead relatively normal lives, except during exacerbations.

    Purpose of review To provide a comprehensive update of the pathogenesis, diagnostic imaging, treatments, and disease activity measurements of juvenile spondyloarthritis (JSpA). Recent findings Genetic and microbiome studies have provided new information regarding possible pathogenesis of JSpA. Recent work suggests that children with JSpA have decreased thresholds for pain in comparison to healthy children. Additionally, pain on physical examination and abnormalities on ultrasound of the entheses are not well correlated. Treatment guidelines for juvenile arthritis, including JSpA, were published by the American College of Rheumatology and are based on active joint count and presence of sacroiliitis. Recent studies have established the efficacy of tumor necrosis factor inhibitors in the symptomatic treatment of axial disease, though their efficacy for halting progression of structural damage is less clear. Newly developed disease activity measures for JSpA include the Juvenile Arthritis Disease Activity Score and the JSpA Disease Activity index. In comparison to other categories of juvenile arthritis, children with JSpA are less likely to attain and sustain inactive disease. Summary Further microbiome and genetic research may help elucidate JSpA pathogenesis. More randomized therapeutic trials are needed and the advent of new composite disease activity measurement tools will hopefully allow for the design of these greatly needed trials. PMID:26002028

    A double-blind urographic and angiographic study was done with the ionic contrast medium meglumine metrizoate and the non-ionic iohexol in 90 patients with diabetes mellitus. Twenty patients were insulin dependent, and 70 non-insulin dependent diabetics. Diabetic patients with decreased as well as normal renal function prior to the examination sustained a reversible and small increase in the plasma creatinine level postexamination. The small increase caused by meglumine metrizoate was significantly higher than the increase caused by iohexol. There was also a significantly higher increase in plasma creatinine among the patients with diabetic nephropathy compared with those without nephropathy. (orig.).

    The purpose of the study was to examine the effect of interleukins, IL-6, IL-8, and IL-15, on insulin-mediated redistribution of Rab4a, an early endosome marker, in mouse 3T3-L1 adipocytes. The interleukins did not affect cell viability; however, cell number was slightly but significantly higher in cultures exposed to IL-8 and IL-15. IL-8 and IL-15 decreased lipid storage in adipocytes, whereas IL-6 had no effect. Rab4A showed cytoplasmic localization, and in control unstimulated adipocytes it was found primarily nearby nucleus, that was supported by cellular fluorescence distribution profile, and by calculated indices, that is, high percentage of near-nuclear area fluorescence and a low mean peripheral cytoplasmic fluorescence/mean near-nuclear fluorescence ratio. Insulin stimulation (100 nmol/l, 30 min) altered the cytoplasmic localization of Rab4a in control adipocytes, which was manifested by its redistribution towards plasma membrane. This effect of insulin was prevented in adipocytes exposed to IL-6, IL-8, or IL-15. We concluded that insulin-dependent Rab4a redistribution, probably reflecting stimulation of vesicle-mediated transport, is inhibited in adipocytes subjected to differentiation in the presence of IL-6, IL-8, or IL-15. Such alterations may be involved in the mechanisms contributing to development of insulin resistance associated with inflammation; however, further studies in this field are required. © 2017 International Federation for Cell Biology.

    2015-06-03

    Diabetes mellitus is usually subdivided into type 1 and type 2. Despite precise criteria, distinction between these two types of diabetes can be difficult because of cases with superposition of the two classes. Adults aged 20 to 40 are particularly at risk of presenting an intermediary type of diabetes and thus are subject to misclassification. The distinction between these subtypes is relevant because of the therapeutic decision and the outcome which relies on insulin supply and therefore the evolution to insulin dependence. Thus, it seems important to review a new and more accurate classification of diabetes to offer a more appropriated care to patients.

    Full Text Available Background: Cardiopulmonary bypass (CPB during coronary artery bypass grafting is thought to contribute significantly to increased blood glucose level and altered blood electrolytes balance during the operation. In this (CABG study, blood electrolytes and glucose during CPB in insulin-dependent diabetic and non-diabetic patients were assessed with special emphasis on the trend of the changes. Materials and Methods: Blood glucose and electrolytes were assessed in 30 insulin-dependent diabetic and 30 non-diabetic patients, classified as class II and III American Society of Anesthesiologist, before, during, and after CPB. Repeated-measures analysis of variance (ANOVA was used to compare the trend of the changes during CPB for the two groups. Results: The trend in blood glucose level did not show any significant difference between two groups ( P = 0.59. For other blood factors, no significant between-group difference was detected except for PaCO 2 ( P = 0.002. Conclusion: The study suggested that the changes in blood electrolytes and the increase in blood glucose level do not differ between insulin dependent diabetic and non-diabetic patients.

    Pancreatologists have often divided research of the pancreas based upon the origin of the function or disease, namely the endocrine or exocrine pancreas. In fact, as a result, many of our meetings and conferences have followed separate paths. Interestingly, among patients with chronic pancreatitis and pancreatic cancer, both disorders of the exocrine pancreas, diabetes is common. However, the clinical features of the diabetes associated with these two differ. Peripheral insulin resistance and hyperinsulinemia are the predominant diabetic traits in pancreatic cancer, while reduced islet cell mass and impaired insulin secretion are observed more often in chronic pancreatitis. The causal relationship between diabetes and pancreatic cancer remains an intriguing but unanswered question. Since diabetes often precedes pancreatic cancer, it is regarded as a potential risk factor for malignancy. On the other hand, there remains the possibility that pancreatic cancer secretes diabetogenic factors. Regardless of how the science ultimately illuminates this issue, there is increasing interest in utilizing screening for diabetes to aid early detection of pancreatic tumor lesions. Therefore, in this issue of Pancreatology and the Web, we explore the topic of diabetes to keep us alert to this very important association, even if we study diseases of the exocrine pancreas.

    Apart from genes in the HLA complex (IDDM1) and the variable number of tandem repeats in the 5' region of the insulin gene (INS VNTR, IDDM2), several other loci have been proposed to contribute to IDDM susceptibility. Recently, linkage and association have been shown between the cytotoxic T lymphocyte-associated protein 4 (CTLA-4) gene on chromosome 2q and IDDM. In a registry-based group of 525 recent-onset IDDM patients immune disease markers (autoantibodies against islet cell cytoplasm (ICA); insulin (IAA); glutamate decarboxylase (GAD65-Ab); IA-2 protein tyrosine phosphatase (IA-2-Ab)) determined within the first week of insulin treatment.

Methods: This study included adolescents aged 12–25 years with type I diabetes or JRA and their parents. At T1, 171/573 (30% response rate adolescents with diabetes or JRA and 229/563 (41% response rate parents completed the questionnaire. At T2, 230/551 (42% response rate adolescents and 220/559 (39% response rate parents still participating in the study completed the questionnaire. A total of 112 adolescents and 143 parents filled in the questionnaires at both T1 and T2.Results: Adolescents perceived significant improvement in their general self-efficacy and reduced quality of life over time, whereas parents’ perceptions did not change. According to adolescents and parents, physical functioning was better among adolescents with diabetes than among those with JRA. Regression analyses of adolescents’ data showed that general self-efficacy at T1 (β = 0.13; p ≤ 0.10 and changes in general self-efficacy (β = 0.22; p ≤ 0.01 predicted quality of life at T2. Parents’ responses revealed that adolescents’ general self-efficacy at T1 (β = 0.16; p ≤ 0.05 and changes in adolescents’ general self-efficacy (β = 0.18; p ≤ 0.05 predicted adolescents’ quality of life at T2. Conclusions: General self-efficacy and changes therein positively affected quality of life in adolescents with diabetes or JRA over time, as perceived by adolescents and parents. These findings emphasise the need for the implementation of interventions aiming to improve general self-efficacy in these populations.

    Coronary artery and peripheral occlusive arterial disease frequently complicate diabetes mellitus, with death due to atherosclerotic coronary artery disease being three times more likely in diabetic compared to non-diabetic patients. The profile of 32 diabetic patients and 32 matched controls who underwent coronary artery bypass (CABG) is studied and their early and late postoperative outcomes are described. The mean age was 61 +\\/- 1 year in both groups. The diabetic group comprised 26 non-insulin dependent and 6 insulin dependent diabetics, who had a mean duration of diabetes of 8.5 years (range 2 months--35 years). The median number of grafts per patient performed in the diabetic group and the control group was 3.5 and 3 respectively. There was no mortality in the series, however considerably greater wound morbidity rates were encountered in the diabetic group when compared to matched controls. One renal transplant patient in the diabetic group suffered irreversible acute tubular necrosis and became dialysis dependent post-operatively. Longterm follow-up showed no longterm mortality in either group, with full relief of angina achieved in 75% of diabetic patients compared with 87.5% of matched controls. In addition diabetic patients suffered greater longterm cardiac morbidity than the control group (21.8% versus 12.5%). The results of this study suggest that CABG is a safe operation for the diabetic patient. Diabetic patients receive satisfactory symptomatic relief of angina, but suffer increased perioperative wound complications and greater incidence of longterm cardiac morbidity.

    The present study, concerning 145 insulin-dependent diabetics showed positive relationships between the severity of retinal disease on the one hand, and body weight, blood pressure, and serum cholesterol level on the other. These relationships remain significant when the duration of the clinical diabetes and the age of the patient are taken into account. Two interpretations are suggested. They are not incompatible. In diabetic subjects, either the increase in blood pressure and serum cholesterol level causes an aggravation of diabetic retinopathy or there exists a common factor at the origin of retinal lesions and of an increase in risk of cardiovascular disease through atherosclerosis.

  20. Disturbances of Haemostasis in Diabetes Mellitus

    2004-01-01

    Full Text Available Diabetes mellitus is associated with disturbances in haemostasis that could contribute to the development of thrombotic complications.The present study was undertaken to determine the behavior of coagulation variables and fibrinolytic system in diabetes mellitus. Forty five diabetic patients and forty five matched controls were evaluated by doing the following haemostatic parameter, prothrombin time, partial thromboplastin time, thrombin time, coagulation factors assay II, VII, IX, & plasma fibrinogen, ADP-induced platelet aggregation, protein C, a2- antiplasmin, PAI and FDPs. Generally diabetic patients have high levels of fibrinogen, a2- antiplasmin, & PAI and lower level of protein C. Other haemostatic parameters did not show statistically significant difference between diabetic patients and control group. Significantally elevated levels of PAI, a2- antiplasmin together with low protein C level in diabetic patients may result in the disturbance of haemostatic balance favoring thrombotic events. Conclusion: High levels of plasma fibrinogen, a2A- antiplasmin with low plasma protein C activity could lead to a prothrombotic tendency in insulin dependent diabetic patients. Moreover, in non-insulin dependent diabetic patients, the above mentioned parameters together with high levels of ADP-induced platelet aggregation and plasminogen activator inhibitor may increase the risk of thrombotic complications. Obesity can be considered as an additional risk factor for development of thrombosis in diabetic patients.

    Diabetic glomerulopathy is the consequence, at the glomerular level, of diabetes. Diagnosis is based on the association of proteinuria, arterial hypertension and an early reduction of glomerular filtration in a diabetic patient, generally insulin-dependent. Diabetic glomerulopathy is a complication of type I diabetes, which begins in childhood or adolescence, but can also be discovered in type II diabetes. A definite diagnosis requires histological evidences ; glomerular clearance measurements ({sup 125}I-iodothalamate or {sup 51}Cr-EDTA) yield important information concerning glomerular filtration. The authors subsequently address pathogenesis and therapeutic regimens, and they report on the particularities of this condition in type II diabetes. (authors). 30 refs., 2 tabs.

    Objective To investigate the cause of high cardiovascular lethality in patients with diabetics mellitus. Methods Sections from autopsied coronary arteries and myocardium of dead patients with non-insulin-dependent diabetics mellitus and 12 dead control subjects were used for histomorphometric studies. Results The coronary atherosclerotic lesion in diabetics patients was not different in severity from those in controls. Nor was there difference in number of myofibers or diameters of myocardic fibers and capillaries.But the capillary density and the ratio of capillary number to myocardic fiber number in diabetics group were significeantly reduced compared with control group(P<0.0 l),and the capillary basement membrane in the former was significantly thicker than in the latter(P<0.01).Conclision The decrease in number of capillaries and the thickening of basement membrane enhance myocardiac vulnerability to further ischemia and hypoxia,which may undelie high lethality of myocardiopathy in diabetic patients.

    Classical interferon-alpha has been shown to be correlated with the development of a variety of autoimmune disorders. A 38 year-old female patient developed simultaneously diabetic ketoacidosis and hyperthyroidism 5 mo following initiation of treatment with pegylated interferon-α and ribavirin for chronic hepatitis C. High titers of glutamic acid decarboxylase,antinuclear and thyroid (thyroid peroxidase and thyroglobulin) antibodies were detected. Antiviral treatment was withdrawn and the patient was treated with insulin for insulin-dependent diabetes mellitus and propranolol for hyperthyroidism. Twelve months after cessation of pegylated interferon-α therapy the patient was euthyroid without any medication but remained insulin-dependent.

    Echinacea purpurea has been used in traditional medicine as a remedy for the treatment and prevention of upper respiratory tract infections and the common cold. Recent investigations have indicated that E. purpurea also has an effect on insulin resistance. A dichloromethane extract of E. purpurea roots was found to enhance glucose uptake in adipocytes and to activate peroxisome proliferator-activated receptor γ. The purpose of the present study was to identify the bioactive compounds responsible for the potential antidiabetic effect of the dichloromethane extract using a bioassay-guided fractionation approach. Basal and insulin-dependent glucose uptake in 3T3-L1 adipocytes were used to assess the bioactivity of extract, fractions and isolated metabolites. A peroxisome proliferator-activated receptor γ transactivation assay was used to determine the peroxisome proliferator-activated receptor γ activating properties of the extract, active fractions and isolated metabolites. Two novel isomeric dodeca-2E,4E,8Z,10E/Z-tetraenoic acid 2-methylbutylamides together with two known C12-alkamides and α-linolenic acid were isolated from the active fractions. The isomeric C12-alkamides were found to activate peroxisome proliferator-activated receptor γ, to increase basal and insulin-dependent glucose uptake in adipocytes in a dose-dependent manner, and to exhibit characteristics of a peroxisome proliferator-activated receptor γ partial agonist.

    Full Text Available Insulin resistance is defined as a reduced ability of insulin to stimulate glucose utilization. C57BL/6 mice fed with a high-fat diet (HFD are a model of insulin resistance. In skeletal muscle, hydrogen peroxide (H2O2 produced by NADPH oxidase 2 (NOX2 is involved in signaling pathways triggered by insulin. We evaluated oxidative status in skeletal muscle fibers from insulin-resistant and control mice by determining H2O2 generation (HyPer probe, reduced-to-oxidized glutathione ratio and NOX2 expression. After eight weeks of HFD, insulin-dependent glucose uptake was impaired in skeletal muscle fibers when compared with control muscle fibers. Insulin-resistant mice showed increased insulin-stimulated H2O2 release and decreased reduced-to-oxidized glutathione ratio (GSH/GSSG. In addition, p47phox and gp91phox (NOX2 subunits mRNA levels were also high (~3-fold in HFD mice compared to controls, while protein levels were 6.8- and 1.6-fold higher, respectively. Using apocynin (NOX2 inhibitor during the HFD feeding period, the oxidative intracellular environment was diminished and skeletal muscle insulin-dependent glucose uptake restored. Our results indicate that insulin-resistant mice have increased H2O2 release upon insulin stimulation when compared with control animals, which appears to be mediated by an increase in NOX2 expression.

    This article describes common forensic evaluations requested of juvenile court mental health evaluators. There has been a legal shift toward criminalization of juvenile court, with a greater emphasis on rights, abandonment of the rehabilitative model, and greater movement of adolescents into the adult criminal court. A resulting shift has been the redefinition of juvenile court forensic evaluations toward the specificity of adult forensic work. The challenge for evaluators is to refine their knowledge of the forensic standards and bring knowledge of development, assessment, and diagnosis in juveniles and interview techniques appropriate to juveniles to improve the evaluation and forensic reports.

    Juvenile polyposis syndrome is a rare autosomal dominant syndrome characterized by multiple distinct juvenile polyps in the gastrointestinal tract and an increased risk of colorectal cancer.The cumulative life-time risk of colorectal cancer is 39% and the relative risk is 34.Juvenile polyps have a distinctive histology characterized by an abundance of edematous lamina propria with inflammatory cells and cystically dilated glands lined by cuboidal to columnar epithelium with reactive changes.Clinically, juvenile polyposis syndrome is defined by the presence of 5 or more juvenile polyps in the colorectum,juvenile polyps throughout the gastrointestinal tract or any number of juvenile polyps and a positive family history of juvenile polyposis.In about 50%-60% of patients diagnosed with juvenile polyposis syndrome a germline mutation in the SMAD4 or BMPR1A gene is found.Both genes play a role in the BMP/TGF-beta signalling pathway.It has been suggested that cancer in juvenile polyposis may develop through the so-alled "landscaper mechanism" where an abnormal stromal environment leads to neoplastic transformation of the adjacent epithelium and in the end invasive carcinoma.Recognition of this rare disorder is important for patients and their families with regard to treatment,follow-up and screening of at risk individuals.Each clinician confronted with the diagnosis of a juvenile polyp should therefore consider the possibility of juvenile polyposis syndrome.In addition, juvenile polyposis syndrome provides a unique model to study colorectal cancer pathogenesis in general and gives insight in the molecular genetic basis of cancer. This review discusses clinical manifestations, genetics, pathogenesis and management of juvenile polyposis syndrome.

    1991-07-01

    The aim of this study was to analyze prevalence data for diabetes mellitus obtained from a household interview of a random sample of the general population by the Department of Health of the Commonwealth of Puerto Rico for the years 1975-1986. Details of the prevalence rate by sex and age were analyzed for the years 1981, 1984, 1985, and 1986 and for the urban and rural population in 1985. The mean prevalence rate of known cases of diabetes showed a tendency to increase from 3.1% in 1975 to 5.1% in 1986. Prevalence rates adjusted for age and sex showed an increase in the mean prevalence for 1986 compared with that of 1981. The prevalence rate was significantly higher for the rural population for the age-group 45-64 yr old and for the urban population for the age-group greater than or equal to 65 yr. The prevalence rate compares with that of Mexican Americans and Puerto Ricans in the New York City area. On the basis of the prevalence data, approximately 90% of the diabetic population is non-insulin dependent and 10% are insulin dependent. Major risk factors thought to explain the increased prevalence of non-insulin-dependent diabetes are increasing longevity of the Puerto Rican population, genetic predisposition, obesity, and changes in life-styles. In conclusion, Puerto Ricans, as other Hispanic Americans, have a higher prevalence of diabetes than the white American population.

    Full Text Available Aims. A new perspective on autoantibodies as pivotal players in the pathogenesis of type 1 diabetes (T1D has recently emerged. Our key objective was to examine whether increased levels of autoantibodies against the β-cell autoantigens glutamic acid decarboxylase (isoform 65 (GADA and insulinoma associated antigen-2A (IA-2A mirrored the 3.4% annual increase in incidence of T1D. Methods. From the Danish Childhood Diabetes Register, we randomly selected 500 patients and 500 siblings for GADA and IA-2A analysis (1997 through 2005. Blood samples were taken within three months after onset. A robust log-normal regression model was used. Nine hundred children and adolescents had complete records and were included in the analysis. Cochran-Armitage test for trend was used to evaluate changes in prevalence of autoantibody positivity by period. Results. No significant changes in levels of GADA and IA-2A were found over our 9-year study period. No trends in autoantibody positivity—in either patients or siblings—were found. Levels of GADA and IA-2A were significantly associated with HLA risk groups and GADA with age. Conclusion. The prevalence of positivity and the levels of GADA and IA-2A have not changed between 1997 and 2005 in newly diagnosed patients with T1D and their siblings without T1D.

    2007-01-01

    Full Text Available Pathogenesis of diabetes is still a mystery for medicine, the real challenge currently being the identification of genetic factors and specific mutations that cause the disease. Heterogeneity of diabetes hampers research, only a few loci inside the human genome being correlated with predisposition for disease till now. Insulin-dependent diabetes - IDDM (T1DM develops through autoimmune destruction of pancreatic beta cells. HLA complex on the short arm of chromosome 6 (6p21, where very important genes responsible for immunological condition of the person are located, plays a very important role in genetic predisposition for T1DM. Beside this region, there are also other loci in the human genome (on chromosomes 1, 2 and 11 where a correlation with T1DM has been shown. Correlation between HLA systems and T1DM was first described for class I alleles, but recently attention has been drawn to class II loci which seem to be the cause of primary predisposition for T1DM. In the case of non-insulin-dependent diabetes - NIDDM (T2DM, the situation proved to be even more complex. Only a few genetic loci on chromosomes 11, 13 and 20 and MODY variant on chromosomes 7 and 12 have been identified by now. There are two theories about genetic basis of T2DM: the first stipulates that the genetic predisposition is determined through numerous loci, each individually responsible for a small part of predisposition; the second claims that there are a limited number of "major" genes probably functioning on a polygenic basis. Further research in this area is definitely needed to enable an accurate calculation of the risks of the disease and possible consequences during a lifetime of a person.

    2016-02-01

    Diabetes mellitus is a complex metabolic disorder associated with an increased risk of microvascular and macrovascular disease; its main clinical characteristic is hyperglycaemia. The last century has been characterised by remarkable advances in our understanding of the mechanisms leading to hyperglycaemia. The central role of insulin in glucose metabolism regulation was clearly demonstrated during the early 1920s, when Banting, Best, Collip and Macleod successfully reduced blood glucose levels and glycosuria in a patient treated with a substance purified from bovine pancreata. Later, during the mid-1930s, clinical observations suggested a possible distinction between 'insulin-sensitive' and 'insulin-insensitive' diabetes. Only during the 1950s, when a reliable measure of circulating insulin was available, was it possible to translate these clinical observations into pathophysiological and biochemical differences, and the terms 'insulin-dependent' (indicating undetectable insulin levels) and 'non-insulin-dependent' (normal or high insulin levels) started to emerge. The next 30 years were characterised by pivotal progress in the field of immunology that were instrumental in demonstrating an immune-mediated loss of insulin-secreting β-cells in subjects with 'insulin-dependent' diabetes. At the same time, new experimental techniques allowing measurement of insulin 'impedance' showed a reduced peripheral effect of insulin in subjects with 'non-insulin-dependent' diabetes (insulin resistance). The difference between the two types of diabetes emerging from decades of observations and experiments was further formally recognised in 1979, when the definitions 'type I' and 'type II' diabetes were introduced to replace the former 'insulin-dependent' and 'non-insulin-dependent' terms. In the following years, many studies elucidated the natural history and temporal contribution of insulin resistance and β-cell insulin secretion in 'type II' diabetes. Furthermore, a central

    Insulin promotes glucose uptake into skeletal muscle through recruitment of glucose transporter 4 (GLUT4) to the plasma membrane. Rab GTPases are molecular switches mobilizing intracellular vesicles, and Rab13 is necessary for insulin-regulated GLUT4-vesicle exocytic translocation in muscle cells. We show that Rab13 engages the scaffold protein MICAL-L2 in this process. RNA interference-mediated knockdown of MICAL-L2 or truncated MICAL-L2 (MICAL-L2-CT) impaired insulin-stimulated GLUT4 translocation. Insulin increased Rab13 binding to MICAL-L2, assessed by pull down and colocalization under confocal fluorescence and structured illumination microscopies. Association was also visualized at the cell periphery using TIRF microscopy. Insulin further increased binding of MICAL-L2 to α-actinin-4 (ACTN4), a protein involved in GLUT4 translocation. Rab13, MICAL-L2, and ACTN4 formed an insulin-dependent complex assessed by pull down and confocal fluorescence imaging. Of note, GLUT4 associated with the complex in response to insulin, requiring the ACTN4-binding domain in MICAL-L2. This was demonstrated by pull down with distinct fragments of MICAL-L2 and confocal and structured illumination microscopies. Finally, expression of MICAL-L2-CT abrogated the insulin-dependent colocalization of Rab13 with ACTN4 or Rab13 with GLUT4. Our findings suggest that MICAL-L2 is an effector of insulin-activated Rab13, which links to GLUT4 through ACTN4, localizing GLUT4 vesicles at the muscle cell periphery to enable their fusion with the membrane.

    The effect of lipohypertrophy at injection sites on insulin absorption has been studied in 12 insulin-dependent diabetic patients. The clearance of 125I-insulin from sites with lipohypertrophy was significantly slower than from complementary nonhypertrophied sites (% clearance in 3 h, 43.8 +/- 3.5 +/- SEM) control; 35.3 +/- 3.9 lipohypertrophy, P less than 0.05). The degree of the effect was variable but sufficient in several patients to be of clinical importance. Injection-site lipohypertrophy is another factor that modifies the absorption of subcutaneously injected insulin.

    A study published in 1982 by Gosden et al. reported unfavorably on the use of the IUD, in this particular case a Cu 7 200, in insulin-dependent diabetic women. In a group of 30 type 1 diabetic patients 11 became pregnant over a period of 1 year. The study did not supply data on parity, age, frequency of coitus, and diabetic control. This letter reports on the cases of 4 insulin-dependent nulligravid women aged 22, 25, 26, and 33, with an average coital frequency of 2-3 times a week. The women had been fitted with Cu T 200 or with Multiload Cu 250 devices; there were no pregnancies during the observed period of 136 women/months. The effectiveness of an IUD depends greatly on the size of the device and on its proper position within the uterine cavity. The Cu 7 200 is a symmetrical, and the vertical stem containing the copper wire is often placed to one side of the cavity, thus creating zones where sperm ascent and blastocyst implantation can happen. Moreover, the Cu 7 200 has a much lower copper-ion-releasing capacity than the Ml 250 or the Cu T 200. The Cu 7 200 also has a higher expulsion and pregnancy rate than other copper IUDs.

    Full Text Available Skin thicking simulating scleroderma is not rare in diabetes mellitus (about 2% among patients with diabetes mellitus, however it is not well known to rheumatologists and endocrinologists. The basis of the syndrome are the abnormalities of collagen and glycosaminoglycans metabolism accompanying by the acid mucopolysaccharides accumulation in the deep part of the reticular dermis. Three cases of pseudosclerodrma in patients with long-standing complicated insulin-dependent diabetes mellitus are presented. The main clinical manifestations of pseudoscleroderma were marked cutaneous induration of the neck, body and proximal parts of extremities liked that of scleredema of Buschke ( 2 patients, and primary paraarticular induration leaded to the flexion contractures liked that of paraneoplastic scleroderma ( I patient. Possible mechanisms of development, clinical and morphological peculiarities and treatment for this syndrome are discussed.

    Full Text Available Background: Diabetic neuropathy is an incapacitating disease that afflicts almost 50 percent of patients with diabetes. A late finding in type 1 diabetes, diabetic neuropathy can be an early finding in non insulin-dependent diabetes. Diabetic neuropathies are divided primarily into two groups, sensorimotor and autonomic. Patients may acquire only one type of diabetic neuropathy or may present with combinations of neuropathies, such as autonomic neuropathy or distal symmetric polyneuropathy, the latter of which the most common form. Motor deficits, orthostatic hypotension, silent cardiac ischemia, hyperhidrosis, vasomotor instability, gastroparesis, bladder dysfunction, and sexual dysfunction can also result from diabetic neuropathy. Strict control of blood sugar, combined with proper daily foot care, is essential to avoid the complications of this disorder. With the potential to afflict any part of the nervous system, diabetic neuropathy should be suspected in all patients with type 2 diabetes as well as patients who have had type 1 diabetes for over five years. Although some patients with diabetic neuropathy notice few symptoms, upon physical examination mild to moderately severe sensory loss may be noted by the physician. Idiopathic neuropathy has been known to precede the onset of type 2 diabetes.

    Juvenile mammary papillomatosis is a benign proliferative disease of young patients, generally under 30 years of age. The most frequent clinical presentation is the existence of an elastic and mobile lymph node of the breast. Anatomopathologically, it is characterized because it presents ductal epithelial hyperplasia, sometimes with marked atypia, and there are numerous cysts having different sizes among the findings. It has been associated with an increase in the incidence of breast cancer, both in the patient herself as well as her family. We review the literature on the subject and present the mammographic and ultrasonographic findings of a 22 year old woman diagnosed of juvenile mammary papillomatosis. (Author) 12 refs.

    Diabetic dyschromatopsia is frequent and is a true complication of diabetes mellitus. Causative factors other than retinopathy have been suggested, but they remain unclear. We have explored the color vision of 100 diabetics aged 16 to 65 (88 insulin-dependent, 12 non-insulin dependent) with Lanthony's D15 desatured panel. Degenerative complications were looked for, especially by fundoscopy and electrophysiological exploration of peripheral nerves using specific scoring. 73% of the diabetics had dyschromatopsia. Dyschromatopsia was significatively more frequent when retinopathy was present (26 out of 30 diabetics with retinopathy versus 47/70 without). We explain the absence of a strict parallelism between dyschromatopsia and retinopathy by the intervention of other factors. Whereas the equilibration of the diabetes was not different between the groups with or without dyschromatopsia, patient age, microalbuminuria, blood pressure and alcohol intake were higher in patients with dyschromatopsia. The greater prevalence of peripheral neuropathy in patients with dyschromatopsia, confirmed by electrophysiology, and independently from the existence of retinopathy, is an indicator of the existence of neuronal disease, whose level remains to be determined. Our results are the indispensible preliminary step to a study of the respective importance of these pathogenic factors.

    To characterize changes in the energy-producing metabolic activity and morphologic ultrastructure of corneal endothelial cells associated with diabetes mellitus. Transplant suitable corneoscleral tissue was obtained from donors aged 50 to 75 years. We assayed 3-mm punches of endothelium-Descemet membrane for mitochondrial respiration and glycolysis activity using extracellular flux analysis of oxygen and pH, respectively. Transmission electron microscopy was used to assess qualitative and quantitative ultrastructural changes in corneal endothelial cells and associated Descemet membrane. For purposes of analysis, samples were divided into four groups based on a medical history of diabetes regardless of type: (1) nondiabetic, (2) noninsulin-dependent diabetic, (3) insulin-dependent diabetic, and (4) insulin-dependent diabetic with specified complications due to diabetes (advanced diabetic). In total, 229 corneas from 159 donors were analyzed. Insulin-dependent diabetic samples with complications due to diabetes displayed the lowest spare respiratory values compared to all other groups (P ≤ 0.002). The remaining mitochondrial respiration and glycolysis metrics did not differ significantly among groups. Compared to nondiabetic controls, the endothelium from advanced diabetic samples had alterations in mitochondrial morphology, pronounced Golgi bodies associated with abundant vesicles, accumulation of lysosomal bodies/autophagosomes, and focal production of abnormal long-spacing collagen. Extracellular flux analysis suggests that corneal endothelial cells of donors with advanced diabetes have impaired mitochondrial function. Metabolic findings are supported by observed differences in mitochondrial morphology of advanced diabetic samples but not controls. Additional studies are needed to determine the precise mechanism(s) by which mitochondria become impaired in diabetic corneal endothelial cells.

    Abstract Background One strategy to help identify susceptibility genes for complex, multifactorial diseases is to map disease loci in a representative animal model of the disorder. The nonobese diabetic (NOD) mouse is a model for human type 1 diabetes. Linkage and congenic strain analyses have identified several NOD mouse Idd (insulin dependent diabetes) loci, which have been mapped to small chromosome intervals, for which the orthologous regions in the human genome can be identified.

    In phylogenesis, becoming of biologicalfunctions and biological reactions proceeds with the purpose ofpermanent increasing of "kinetic perfection ". The main role belongs to factors ofphysical, chemical and biological kinetics, their evaluation using systemic approach technique under permanent effect of natural selection. The late-in-phylogenesis insulin, proceeded with, in development of biological function of locomotion, specialization of insulin-dependent cells: skeletal myocytes, syncytium of cardiomyocytes, subcutaneous adipocytes, periportal hepatocytes, Kupffer's macrophages and β-cells of islets of pancreas. The insulin initiated formation of new, late in phylogenesis, large pool of fatty cells-subcutaneous adipocytes that increased kinetic parameters of biological function of locomotion. In realization of biological function of locomotion only adipocytes absorb exogenous mono unsaturated and saturated fatty acids in the form of triglycerides in composition of oleic and palmitic lipoproteins of very low density using apoE/B-100 endocytosis. The rest of insulin-dependent cells absorb fatty acids in the form of unesterified fatty acids from associates with albumin and under effect of CD36 of translocase offatty acids. The insulin in all insulin-depended cells inhibits biological reaction of lipolysis enhancing contributing into development of lipoidosis. The insulin expresses transfer offatty acids in the form of unsaturated fatty acids from adipocytes into matrix of mitochondria. The insulin supplies insulin-dependent cells with substrates for acquiring energy subject to that in pool of unsaturated fatty acids in adipocytes prevails hydrophobic palmitic unsaturated fatiy acid that slowly passes into matrix through external membrane ofmitochondria; oxidases of mitochondria so slowly implement its β-oxidation that content of exogenous palmitic unsaturatedfatty acid can't be higher than phylogenetic, physiological level - 15% of all amount offatty acids

    Previous studies in rat hepatocytes demonstrated that insulin-dependent apolipoprotein (apo) B degradation (IDAD) is lost when cells are maintained for 3 d under enriched culture conditions. Loss of IDAD correlates with increased expression of protein tyrosine phosphatase 1B (PTP1B) known to be associated with resistance to insulin signaling in the liver. McArdle RH7777 hepatoma (McA) cells cultured in serum containing medium are resistant to IDAD; demonstrate a 30% increase in apo B secretion, and express increased levels of PTP1B protein and mRNA. In addition, insulin-stimulated Class I phosphatidylinositide 3-kinase (PI3K) activity of anti-pY immunoprecipitates is severely blunted. IDAD resistance in McA cells correlates with diminished translocation of insulin-stimulated pY-IRS1 to intracellular membranes. Incubation of McA cells with RK682, a protein tyrosine phosphatase inhibitor, is sufficient to restore IDAD in resistant McA cells. Overall, results further support the importance of Class I PI3K activity in IDAD, and suggest that loss of this activity is sufficient to cause resistance. Although other factors are involved in downstream events including sortilin binding to apo B, autophagy, and lysosomal degradation, loss of signal generation and reduced localization of Class I PI3K to intracellular membranes plays a significant role in IDAD resistance.

    Sexual offending by juveniles accounts for a sizable percentage of sexual offenses, especially against young children. In this article, recent research on female juvenile sex offenders (JSOs), risk factors for offending in juveniles, treatment, and the ways in which these youth may differ from general delinquents will be reviewed. Most JSOs do not go on to develop paraphilic disorders or to commit sex offenses during adulthood, and as a group, they are more similar to nonsexual offending juvenile delinquents than to adult sex offenders. Recent research has elucidated some differences between youth who commit sex offenses and general delinquents in the areas of atypical sexual interests, the use of pornography, and early sexual victimization during childhood.

    The paper reviews some recent articles on hypoglycaemia, and the prevalence of road traffic accidents, respectively, as experienced by diabetic patients. Two aspects are particularly emphasised: according to recent recommendations, type-1 (insulin-dependent) diabetic patients are advised to strive for near-normoglycaemia, which may, in turn, increase their risk of getting hypoglycaemia; hence, car driving may become particularly dangerous for insulin-treated patients. The recent literature contradicts the widely held belief that insulin-treated diabetics are more frequently involved in road traffic accidents than the average population. However, there are some subpopulations among the type-1 diabetic patients who may need special safeguards against hypoglycaemia-induced road traffic accidents; this issue is being discussed in the paper in more detail.
