Effect of hyperglycemia-hyperinsulinemia on whole body and regional fatty acid metabolism. (1/1504)

The effects of combined hyperglycemia-hyperinsulinemia on whole body, splanchnic, and leg fatty acid metabolism were determined in five volunteers. Catheters were placed in a femoral artery and vein and a hepatic vein. U-13C-labeled fatty acids were infused, once in the basal state and, on a different occasion, during infusion of dextrose (clamp; arterial glucose 8.8 +/- 0.5 mmol/l). Lipids and heparin were infused together with the dextrose to maintain plasma fatty acid concentrations at basal levels. Fatty acid availability in plasma and fatty acid uptake across the splanchnic region and the leg were similar during the basal and clamp experiments. Dextrose infusion decreased fatty acid oxidation by 51.8% (whole body), 47.4% (splanchnic), and 64.3% (leg). Similarly, the percent fatty acid uptake oxidized decreased at the whole body level (53 to 29%), across the splanchnic region (30 to 13%), and in the leg (48 to 22%) during the clamp. We conclude that, in healthy men, combined hyperglycemia-hyperinsulinemia inhibits fatty acid oxidation to a similar extent at the whole body level, across the leg, and across the splanchnic region, even when fatty acid availability is constant.  (+info)

Relative contribution of insulin and its precursors to fibrinogen and PAI-1 in a large population with different states of glucose tolerance. The Insulin Resistance Atherosclerosis Study (IRAS). (2/1504)

Hyperinsulinemia is associated with the development of coronary heart disease. However, the underlying mechanisms are still poorly understood. Hypercoagulability and impaired fibrinolysis are possible candidates linking hyperinsulinism with atherosclerotic disease, and it has been suggested that proinsulin rather than insulin is the crucial pathophysiological agent. The aim of this study was to investigate the relationship of insulin and its precursors to markers of coagulation and fibrinolysis in a large triethnic population. A strong and independent relationship between plasminogen activator inhibitor-1 (PAI-1) antigen and insulin and its precursors (proinsulin, 32-33 split proinsulin) was found consistently across varying states of glucose tolerance (PAI-1 versus fasting insulin [proinsulin], r=0.38 [r=0.34] in normal glucose tolerance; r=0.42 [r=0.43] in impaired glucose tolerance; and r=0.38 [r=0.26] in type 2 diabetes; all P<0.001). The relationship remained highly significant even after accounting for insulin sensitivity as measured by a frequently sampled intravenous glucose tolerance test. In a stepwise multiple regression model after adjusting for age, sex, ethnicity, and clinic, both insulin and its precursors were significantly associated with PAI-1 levels. The relationship between fibrinogen and insulin and its precursors was significant in the overall population (r=0.20 for insulin and proinsulin; each P<0.001) but showed a more inconsistent pattern in subgroup analysis and after adjustments for demographic and metabolic variables. Stepwise multiple regression analysis showed that proinsulin (split products) but not fasting insulin significantly contributed to fibrinogen levels after adjustment for age, sex, clinic, and ethnicity. Decreased insulin sensitivity was independently associated with higher PAI-1 and fibrinogen levels. In summary, we were able to demonstrate an independent relationship of 2 crucial factors of hemostasis, fibrinogen and PAI-1, to insulin and its precursors. These findings may have important clinical implications in the risk assessment and prevention of macrovascular disease, not only in patients with overt diabetes but also in nondiabetic subjects who are hyperinsulinemic.  (+info)

The contributions of oestrogen and growth factors to increased adrenal androgen secretion in polycystic ovary syndrome. (3/1504)

Adrenal hyperandrogenism is prevalent in many women with polycystic ovary syndrome (PCOS), although the expression of this enhanced secretion may be heterogeneous. Since no single factor acts in isolation, this study was performed to assess the influence of oestradiol (total and unbound), insulin, insulin-like growth factor (IGF)-I, IGF-II and the binding proteins IGFBP-I, and IGFBP-3, on basal and adrenocorticotrophic hormone (ACTH) stimulated adrenal androgen secretion in 25 women with PCOS and 10 matched ovulatory controls. Women with PCOS exhibited elevations of all androgens as well as unbound oestradiol, insulin and non-IGFBP-1 bound IGF-I. Positive correlations were noted between oestrogen and basal and ACTH stimulated delta 5 adrenal androgens. Serum IGF-I was only correlated with basal dehydroepiandrosterone sulphate (DHEA-S), while insulin exhibited a strong correlation with the delta 4 pathway and androstenedione formation in particular. This correlation was also confirmed by dividing the PCOS group into those women with and without hyperinsulinaemia. The activity of 17,20 lyase favouring androstenedione was increased in the hyperinsulinaemic women. By multivariate analyses, body mass index did not influence these findings. Although there are inherent difficulties in making major conclusions based on correlative analyses, it is suggested that oestrogen may have a greater influence on enhancing delta 5 adrenal androgen secretion, and insulin a greater effect on the delta 4 pathway. In turn, the relative importance of these influences may contribute to the heterogeneous nature of adrenal hyperandrogenism in PCOS.  (+info)

Pancreatic exocrine and endocrine function after pancreatectomy for persistent hyperinsulinaemic hypoglycaemia of infancy. (4/1504)

AIM: To evaluate long term detailed pancreatic endocrine and exocrine function in children with persistent hyperinsulinaemic hypoglycaemia of infancy (PHHI) after 85-95% pancreatectomy. METHODS: Six children with PHHI between 0.9 and 12.7 years after pancreatic resection underwent clinical and investigative follow up at 1.0 to 14.9 years of age. One child with PHHI who had not had pancreatectomy was also assessed. Standard endocrine assessment, pancreatic magnetic resonance imaging (MRI), and detailed direct and indirect tests of exocrine pancreatic function were performed. RESULTS: Pancreozymin-secretin stimulation test results were normal in only one child, borderline in two, and deficient in four, one of whom requires daily pancreatic enzyme supplements. Pancreolauryl tests performed in three children were borderline in two and abnormal in the other. Only one child had low faecal chymotrypsin values. One child developed insulin dependent diabetes at 9 years and two children at 1.0 and 13.3 years require diazoxide to maintain normoglycaemia. MRI showed no major regrowth of the pancreatic remnant after resection (n = 5). CONCLUSIONS: Clinical evidence of endocrine or exocrine dysfunction has developed in only two patients to date, but detailed pancreatic function testing suggests subclinical deficiency in all but one of our patients with PHHI. Although 95% pancreatectomy results in postoperative control of blood glucose, subclinical pancreatic insufficiency is present on long term follow up and development of diabetes mellitus and exocrine failure remain ongoing risks.  (+info)

Long-term follow up of persistent hyperinsulinaemic hypoglycaemia of infancy. (5/1504)

Twenty six children with hypoglycaemia were diagnosed and followed between 1975 and 1995. Diagnosis was confirmed by a high insulin:glucose ratio, and low free fatty acid and 3-hydroxybutyrate on fasting. All patients were treated with diazoxide at a maximum dose of 20 mg/kg/day. Requirement of a higher dose was considered as a failure of medical treatment and an indication for surgery. Sixteen children Responded to diazoxide; 10 failed to respond and underwent pancreatic resection. Six of the latter group started with symptoms in the neonatal period. Eleven of the 26 children have neurological sequelae. Head growth and neurological outcome correlated well. Additionally, non-specific electroencephalogram abnormalities (slow waves) appear to be indicative of subclinical hypoglycaemia during follow up.  (+info)

Hyperinsulinism: molecular aetiology of focal disease. (6/1504)

Persistent hypoglycaemia in infancy is most commonly caused by hyperinsulinism. A case is reported of the somatic loss of the maternal 11p in an insulin secreting focal adenoma in association with a germline SUR-1 mutation on the paternal allele in a baby boy with hyperinsulinism diagnosed at 49 days old. A reduction to homozygosity of an SUR-1 mutation is proposed as a critical part of the cause of focal hyperinsulinism.  (+info)

The structure and function of the ATP-sensitive K+ channel in insulin-secreting pancreatic beta-cells. (7/1504)

ATP-sensitive K+ channels (KATP channels) play important roles in many cellular functions by coupling cell metabolism to electrical activity. The KATP channels in pancreatic beta-cells are thought to be critical in the regulation of glucose-induced and sulfonylurea-induced insulin secretion. Until recently, however, the molecular structure of the KATP channel was not known. Cloning members of the novel inwardly rectifying K+ channel subfamily Kir6.0 (Kir6.1 and Kir6.2) and the sulfonylurea receptors (SUR1 and SUR2) has clarified the molecular structure of KATP channels. The pancreatic beta-cell KATP channel comprises two subunits: a Kir6.2 subunit and an SUR1 subunit. Molecular biological and molecular genetic studies have provided insights into the physiological and pathophysiological roles of the pancreatic beta-cell KATP channel in insulin secretion.  (+info)

Surgery-induced insulin resistance in human patients: relation to glucose transport and utilization. (8/1504)

To investigate the underlying molecular mechanisms for surgery-induced insulin resistance in skeletal muscle, six otherwise healthy patients undergoing total hip replacement were studied before, during, and after surgery. Patients were studied under basal conditions and during physiological hyperinsulinemia (60 microU/ml). Biopsies of vastus lateralis muscle were used to measure GLUT-4 translocation, glucose transport, and glycogen synthase activities. Surgery reduced insulin-stimulated glucose disposal (P < 0.05) without altering the insulin-stimulated increase in glucose oxidation or suppression of endogenous glucose production. Preoperatively, insulin infusion increased plasma membrane GLUT-4 in all six subjects (P < 0.05), whereas insulin-stimulated GLUT-4 translocation only occurred in three patients postoperatively (not significant). Moreover, nonoxidative glucose disposal rates and basal levels of glycogen synthase activities in muscle were reduced postoperatively (P < 0.05). These findings demonstrate that peripheral insulin resistance develops immediately postoperatively and that this condition might be associated with perturbations in insulin-stimulated GLUT-4 translocation as well as nonoxidative glucose disposal, presumably at the level of glycogen synthesis.  (+info)

Hyperinsulinism can occur throughout childhood but is most common in infancy. Persistent hyperinsulinemic hypoglycemia of infancy (PHHI) is the most important cause of hypoglycemia in early infancy. The excessive secretion of insulin is responsible for profound hypoglycemia and requires aggressive treatment to prevent severe and irreversible brain damage. Onset can be in the neonatal period or later, with the severity of hypoglycemia decreasing with age. PHHI is a heterogeneous disorder with two histopathological lesions, diffuse (DiPHHI) and focal (FoPHHI), which are clinically indistinguishable. FoPHHI is sporadic and characterized by somatic islet-cell hyperplasia. DiPHHI corresponds to a functional abnormality of insulin secretion in the whole pancreas and is most often recessive although rare dominant forms can occur, usually outside the newborn period. Differentiation between focal and diffuse lesions is important because the therapeutic approach and genetic counselling differ radically. ...

Background: Most infants with persistent hyperinsulinaemic hypoglycaemia (PHH) are born large for gestational age (LGA) due to excessive anabolic effect of prenatal hyperinsulinism. However, other auxological characteristics than weight in infants with PHH have not been described well.. Objective: The objective of this investigation was to characterize anthropometric parameters at birth (weight, length, and head circumference) in PHH compared with those in idiopathic LGA.. Method: Clinical data in full term birth for PHH and idiopathic LGA were retrospectively collected at two institutions. We excluded infants of diabetic mothers or those with known overgrowth syndrome. Variables analysed included birth weight SDS, length SDS, and head circumference SDS. The variables between PHH and idiopathic LGA were compared using the Mann Whitney U test.. Results: The present study included seven infants with PHH and 134 with idiopathic LGA. The birth weight SDS in PHH (median, 3.03; range, 1.46 to 3.67) ...
TY - CHAP. T1 - Hyperinsulinism of infancy. T2 - Localization of focal forms. AU - Hardy, Olga T.. AU - Stanley, Charles A.. PY - 2006. Y1 - 2006. N2 - Congenital hyperinsulinism is the most common cause of persistent hypoglycemia in infants and children (1). Infants with severe forms of the disorder (formerly termed nesidioblastosis) present with hypoglycemia in the newborn period and are at high risk of seizures, permanent brain damage, and retardation. Infants with congenital hyperinsulinism may have either focal or diffuse abnormalities of the pancreatic β cells. In cases with diffuse disease, an underlying defect in the β-cell adenosoine triphosphate (ATP)-dependent potassium channel may be present, caused by recessive loss of function mutations of the two genes encoding the KATP channel, SUR1 or Kir6.2 (1,2). These mutations may also cause focal hyperinsulinism in which there is an area of β-cell adenomatosis due to loss of heterozygosity for the maternal 11p region and expression of a ...
Congenital hyperinsulinaemic hypoglycaemia (HH) is characterised by the inappropriate secretion of insulin despite low blood glucose levels. Hyperinsulinism may be transient or permanent. Transient hyperinsulinism can occur in babies of diabetic mothers who have been exposed to maternal hyperglycaemia before birth. Babies who have sustained perinatal asphyxia and those with intrauterine growth restriction are also at increased…
Hyperinsulinemia is common in obesity, but whether it plays a role in intramyocellular triglyceride (imcTG) buildup is unknown. In this study, hyperinsulinemic-euglycemic clamp experiments were performed in overnight-fasted lean and high-fat-fed obese rats, awake, to determine the effect of insulin on imcTG synthesis (incorporation of [(14)C]glycerol, [(14)C]glucose, and [(3)H]oleate). Insulin infusion at 25 (low insulin) and 100 (high insulin) pmol/kg/min increased plasma insulin by 5- and 16-fold, respectively, whereas plasma and intramyocellular glycerol, FFAs, triglycerides, and glucose levels were maintained at their basal levels by co-infusion of exogenous glycerol, FFAs, and triglycerides at fixed rates and glucose at varying rates. In obese rats, insulin suppressed incorporation of glycerol into the imcTG-glycerol moiety dose dependently (P | 0.01-P | 0.001) in gastrocnemius and tibialis anterior, but only the high insulin suppressed it in soleus (P | 0.05). The low insulin suppressed glucose

Josie will be 8 weeks old tomorrow and today she was diagnosed with hyperinsulinism. Shes had a hard time regulating her blood sugar and shes not gaining weight as quickly as the doctors would like. We have to do more testing to determine if there is a generic cause for it or if its related to the IUGR. They think it can be managed with medication but this diagnosis has bought us at least another 5 days in the NICU and when she comes home Ill have to check her blood sugar 2-3 times a day. Im just feeling so depressed and defeated at this point. Shes doing all the major things (breathing, eating, etc) but we just cant get past this blood sugar thing. Has anybody else experienced this with their IUGR baby? Even if you havent dealt with this, I could use some positivity right now. Shes so amazing and I feel like I just keep failing her

The Shapedown BC program was a lifeline for my son Brad and our family. We noticed Brads weight gain when he was in grade two, and when he was 12 years old we discovered that he had high insulin levels and high cholesterol. It became more about his health and his heart, not just his weight. Shapedown helped us make changes and set goals as a family. After the 10-week program ended, I noticed that Brad had taken what he learned and was applying it to his life - he was making better choices about meals and exercise, and had gained more confidence, too. My husband and I even lost a bit of weight! Shapedown was truly a difference maker for us, and we are thrilled to see that the program will be expanded to more kids and families across the province ...

Familial persistent hyperinsulinemic hypoglycemia of infancy (PHHI), an autosomal recessive disorder characterized by unregulated insulin secretion, is linked to chromosome 11p14-15.1. The newly cloned high-affinity sulfonylurea receptor (SUR) gene, a regulator of insulin secretion, was mapped to 11p15.1 by means of fluorescence in situ hybridization. Two separate SUR gene splice site mutations, which segregated with disease phenotype, were identified in affected individuals from nine different families. Both mutations resulted in aberrant processing of the RNA sequence and disruption of the putative second nucleotide binding domain of the SUR protein. Abnormal insulin secretion in PHHI appears to be caused by mutations in the SUR gene. ...
Looking for online definition of alimentary hyperinsulinism in the Medical Dictionary? alimentary hyperinsulinism explanation free. What is alimentary hyperinsulinism? Meaning of alimentary hyperinsulinism medical term. What does alimentary hyperinsulinism mean?
An experimental approach based on genetic studies has offered new insights into the pathophysiology of persistent hyperinsulinemia of infancy. This review highlights these advances, with special emphasis on the forms of hyperinsulinemia that are associated with defects of the adenosine triphosphate (ATP)-dependent potassium (KATP) channel, a key regulator of insulin secretion in the pancreatic islets.. Persistent hyperinsulinemia of infancy has been known as nesidioblastosis, persistent hyperinsulinemic hypoglycemia of infancy, and familial hyperinsulinism since its initial recognition as a clinical entity in the 1950s. More prevalent forms of hypoglycemia that are transitory and occur in the immediate newborn period must be differentiated from persistent hyperinsulinemia of infancy, which is defined by inappropriate insulin secretion in the presence of profound hypoglycemia. The characteristic associated clinical findings (Table 1⇓ ), including inappropriate glucose-to-insulin ratios, ...

Congenital Hyperinsulinism International (CHI) has developed a patient-reported registry called the HI Global Registry with its partners to improve the understanding of HI, and advance research for better treatments and patient care. The registry consists of a series of online surveys that asks the participant questions about the patients experience with the disorder over his or her lifetime. The data is stored on a secure cloud-based platform and made anonymous by removing any personal details that can identify the patient. This information is then combined with patient data from around the world to produce research reports that can be studied by disease experts and researchers. The HI Global Registry is open for registration now- click here to visit the registry website.. Patients and their legally authorized representatives will be able to participate in the HI Global Registry by registering online and consenting to participate in the study. After consenting, participants will be directed to ...
Background: Insulin is an important metabolic hormone that also has cardiovasculat effects. Insulin resistance is characterized by decreased tissue sensitivity to insulin, and is a part of two important endocrine diseases in horses, Equine Metabolic Syndrome and Pituitary Pars Intermedia Dysfunction. Both diseases carry an increased risk for laminitis.. Decreased insulin sensitivity in people has been shown to lead to a decrease of the vasodilating effect of insulin. Increased baseline blood pressure and heart rate have also been seen in insulin resistant dogs and rats. The effect of induced hyperinsulinemia on cardiovascular markers such as heart rate, blood pressure and peripheral blood flow has been studied in healthy as well as insulin resistent people and laboratory animals. Studies regarding the effect of insulin resistance and induced hyperinsulinemia on cardiovascular markers in horses are scarce. The purpose of this study was to compare heart rate, blood pressure and hoof wall surface ...
Hyperinsulinemia and insulin resistance have been postulated to link obesity and hypertension. Evidence supporting this concept derives mainly from epidemiological studies showing a correlation between insulin resistance, hyperinsulinemia, and blood pressure and from short-term studies suggesting that insulin has renal and cardiovascular actions that, if sustained, could elevate blood pressure. However, a cause-and-effect relation between insulin and hypertension has not been clearly established. Recent studies indicate that chronic hyperinsulinemia, similar to that found in obese hypertensive patients, did not raise blood pressure in normal dogs, even when renal excretory capability was reduced by prior removal of kidney mass. Chronic insulin infusion also failed to elevate blood pressure in dogs maintained on a high sodium intake and did not potentiate the long-term blood pressure responses to angiotensin II or norepinephrine. The presence or absence of insulin resistance may not be a major ...

The aim of the study was to examine the extent to which hyperinsulinemia is associated with hypertension in the elderly Chinese and whether interventional therapy can improve hyperinsulinemia. This study included 144 institutionalized, healthy, nondiabetic elderly Chinese subjects were examined. Their ages ranged from 65 to 83 years, with a mean of 74 years. There were 72 men and 72 women. Forty-eight subjects were normotensive, and 96 were hypertensive; average body mass index (BMI) was 23. The hypertensive subjects could be divided into two groups: (A) untreated hypertensive (n = 48) and (B) treated ...

This study has investigated the effects of clamped hyperinsulinemic euglycemia and acute and repeated 2-h episodes of moderate hyperinsulinemic hypoglycemia (2.9 mmol/L) on endothelial function, fibrinolytic balance, and proinflammatory and proatherothrombotic mechanisms in healthy man. Our results demonstrate that acute hypoglycemia reduces endogenous NO-mediated endothelial vasodilation, activates inflammatory processes, impairs fibrinolytic balance, and increases proatherothrombotic mechanisms. Secondly, repeated episodes of hypoglycemia can further impair vascular function by additionally reducing both endogenous and exogenous NO-mediated endothelial function and increasing TAT complex formation.. Recent large randomized controlled trials investigating the effects of intensifying glucose control both in hospitals and in outpatient settings have demonstrated an association with hypoglycemia and severe cardiovascular outcomes and even death (5,8). The in vivo vascular pathophysiologic ...
Helpful, trusted answers from doctors: Dr. Sneid on lupus low blood sugar: This is often a complication of diabetes therapy, and blood glucose management, but certain tumors, like insulinomas, among others, can cause this, and many of those patients have a family history of those tumors. Some others also have naturally low blood sugar, and that can be due to genetics. Congenital hyperinsulinism might be such a case, as might inborn errors of carbohydrate metabolism.

It is clearly recognized that patients with NIDDM have an increased risk for CHD. Recent data indicate that persons with glucose concentrations in the nondiabetic range also may be at higher risk for CHD. These associations may not represent cause and effect, however. Emerging data suggest that hyperglycemia and CHD may both arise from hyperinsulinemia/insulin resistance. In support of this hypothesis are studies showing that NIDDM and CHD have many risk factors in common, including age, elevated blood pressure, dyslipidemia, adiposity, and a central pattern of fat distribution. Moreover, these risk factors are frequent concomitants of hyperinsulinemia, itself a risk factor for CHD and perhaps for NIDDM. Although the duration of NIDDM has been infrequently related to risk of CHD, the authors hypothesize that duration of hyperinsulinemia/insulin resistance would be a more sensitive marker for risk of CHD. The relation of IDDM to CHD is a different situation. The etiological process leading to ...
