0.05) but was similar with ultralente (20 ± 6 h). NPH and ultralente exhibited a peak concentration and action (at 4.5 ± 0.5 and 10.1 ± 1 h, respectively) followed by waning, whereas glargine had no peak but had a flat concentration/action profile mimicking CSII. Interindividual variability (calculated as differences in SD of plasma insulin concentrations and glucose infusion rates in different treatments) was lower with glargine than with NPH and ultralente (P < 0.05) but was similar with glargine and CSII (NS). In conclusion, NPH and ultralente are both peak insulins. Duration of action of ultralente is greater, but intersubject variability is also greater than that of NPH. Glargine is a peakless insulin, it lasts nearly 24 h, it has lower intersubject variability than NPH and ultralente, and it closely mimics CSII, the gold standard of basal insulin replacement. Diabetes 49:2142-2148, 2000 T he goal of treatment of type 1 diabetes is maintenance of long-term near-normoglycemia to prevent the onset and/or progression of long-term complications (1,2). At present, this goal is feasible with physiological models of insulin replacement (3), provided that patients are appropriately educated about the strategy of intensive insulin therapy (4,5). However, several obstacles, such as day-to-day variability in insulin requirements and slow (6) and variable absorption (7) of insulin from the subcutaneous (SC) site of injection, make it difficult for type 1 diabetic patients to maintain long-term near-normoglycemia.The DNA-recombinant technique has led to synthesis of the short-acting human insulin analogs lispro and aspart, which are absorbed faster than human regular insulin and improve 1-and 2-h postprandial blood glucose levels (8). However, better postprandial blood glucose control with short-acting insulin analogs results in improvement in glycemic control in the long term only by the extent to which replacement of basal insulin is optimized at the same time, either by continuous subcutaneous insulin infusion (CSII) or multiple daily administrations of NPH (8). The latter regimen results in lower HbA 1c (9), with no increase (9) or a decrease in the frequency of hypoglycemia compared with the regimen based on mealtime administration of human regular insulin and bedtime NPH (8). In turn, less frequent hypoglycemia results in better awareness of and counterregulation to hypoglycemia in the long term (10). However, the approach of multiple daily injections of NPH or CSII may be too demanding for the majority of patients worldwide who use mealtime administration of short-acting insulin analogs.An ideal basal insulin candidate is a peakless long-lasting preparation that mimics the flat interprandial insulin secretion of nondiabetic subjects, with reproducible SC absorption. The presently available intermediate-acting (NPH) or long-acting (ultralente) insulin preparations are poor surrogates for the ideal basal insulin, primarily because of their peak-action profile (11,12) and day-to-day variability in SC absorption (7)....
Background Surgery for obesity and metabolic diseases has been evolved in the light of new scientific evidence, long-term outcomes and accumulated experience. EAES has sponsored an update of previous guidelines on bariatric surgery. Methods A multidisciplinary group of bariatric surgeons, obesity physicians, nutritional experts, psychologists, anesthetists and a patient representative comprised the guideline development panel. Development and reporting conformed to GRADE guidelines and AGREE II standards. Results Systematic review of databases, record selection, data extraction and synthesis, evidence appraisal and evidence-todecision frameworks were developed for 42 key questions in the domains Indication; Preoperative work-up; Perioperative management; Non-bypass, bypass and one-anastomosis procedures; Revisional surgery; Postoperative care; and Investigational procedures. A total of 36 recommendations and position statements were formed through a modified Delphi procedure. and Other Interventional Techniques Disclaimer This clinical practice guideline has been developed under the auspice of the European Association for Endoscopic Surgery (EAES). It is intended to be used primarily by health professionals (e.g. surgeons, anesthetists, physicians) and to assist in making informed clinical decisions on diagnostic measures and therapeutic management. It is also intended to inform individual practice of allied health professionals (e.g. surgical nurses, dietitians, physical rehabilitation therapists, psychologists); to inform strategic planning and resource management by healthcare authorities (e.g. regional and national authorities, healthcare institutions, hospital administration authorities); and to inform patients wishing to obtain an overview of the condition of interest and its management. The use of recommendations contained herein must be informed by supporting evidence accompanying each recommendation and by research evidence that might not have been published by the time of writing the present document. Users must thus base their actions informed by newly published evidence at any given point Electronic supplementary material The online version of this article (
To test the hypothesis that hypoglycemia unawareness is largely secondary to recurrent therapeutic hypoglycemia in IDDM, we assessed neuroendocrine and symptom responses and cognitive function in 8 patients with short-term IDDM (7 yr) and hypoglycemia unawareness. Patients were assessed during a stepped hypoglycemic clamp, before and after 2 wk and 3 mo of meticulous prevention of hypoglycemia, which resulted in a decreased frequency of hypoglycemia (0.49 +/- 0.05 to 0.045 +/- 0.03 episodes/patient-day) and an increase in HbA1c (5.8 +/- 0.3 to 6.9 +/- 0.2%) (P < 0.05). We also studied 12 nondiabetic volunteer subjects. At baseline, lower than normal symptom and neuroendocrine responses occurred at lower than normal plasma glucose, and cognitive function deteriorated only marginally during hypoglycemia. After 2 wk of hypoglycemia prevention, the magnitude of symptom and neuroendocrine responses (with the exception of glucagon and norepinephrine) nearly normalized, and cognitive function deteriorated at the same glycemic threshold and to the same extent as in nondiabetic volunteer subjects. At 3 mo, the glycemic thresholds of symptom and neuroendocrine responses normalized, and surprisingly, some of the responses of glucagon recovered. We concluded that hypoglycemia unawareness in IDDM is largely reversible and that intensive insulin therapy and a program of intensive education may substantially prevent hypoglycemia and at the same time maintain the glycemic targets of intensive insulin therapy, at least in patients with IDDM of short duration.
To assess the relative roles of insulin and hypoglycaemia on induction of neuroendocrine responses, symptoms and deterioration of cognitive function (12 cognitive tests) during progressive decreases in plasma glucose, and to quantitate glycaemic thresholds, 22 normal, non-diabetic subjects (11 males, 11 females) were studied on four occasions: prolonged fast (n = 8, saline euglycaemia study, SA-EU), stepped hypoglycaemia (plasma glucose plateaus of 4.3, 3.7, 3 and 2.3 mmol/l) or euglycaemia during insulin infusion at 1 and 2 mU.kg-1.min-1 (n = 22, high-insulin hypoglycaemia and euglycaemia studies, HI-INS-HYPO and HI-INS-EU, respectively), and stepped hypoglycaemia during infusion of insulin at 0.35 mU.kg-1.min-1 (n = 9, low-insulin hypoglycaemia study, LO-INS-HYPO). Insulin per se (SA-EU vs HI-INS-EU), suppressed plasma glucagon (approximately 20%) and pancreatic polypeptide (approximately 30%), whereas it increased plasma noradrenaline (approximately 10%, p < 0.05). Hypoglycaemia per se (HI-INS-HYPO vs HI-INS-EU) induced responses of counterregulatory hormones (CR-HORM), symptoms and deteriorated cognitive function. With the exception of suppression of endogenous insulin secretion, which had the lowest glycaemic threshold of 4.44 +/- 0.06 mmol/l, pancreatic polypeptide, glucagon, growth hormone, adrenaline and cortisol had similar glycaemic thresholds (approximately 3.8-3.6 mmol/l); noradrenaline (3.1 +/- 0.0 mmol/l), autonomic (3.05 +/- 0.06 mmol/l) and neuroglycopenic (3.05 +/- 0.05 mmol/l) symptoms had higher thresholds. All 12 tests of cognitive function deteriorated at a glycaemic threshold of 2.45 +/- 0.06 mmol/l, but 7 out of 12 tests were already abnormal at a glycaemic threshold of 2.89 +/- 0.06 mmol/l. Although all CR-HORM had a similar glycaemic threshold, the lag time of response (the time required for a given parameter to increase) of glucagon (15 +/- 1 min) and growth hormone (14 +/- 3 min) was shorter than adrenaline (19 +/- 3 min) and cortisol (39 +/- 4 min) (p < 0.05). With the exception of glucagon (which was suppressed) and noradrenaline (which was stimulated), insulin per se (HI-INS-HYPO vs LO-INS-HYPO) did not affect the responses of CR-HORM, and did not influence the symptoms or the cognitive function during hypoglycaemia. Despite lower responses of glucagon, adrenaline and growth hormone (but not thresholds) in females than males, females were less insulin sensitive than males during stepped hypoglycaemia.
In clinical practice, combined heart and liver dysfunctions coexist in the setting of the main heart and liver diseases because of complex cardiohepatic interactions. It is becoming increasingly crucial to identify these interactions between heart and liver in order to ensure an effective management of patients with heart or liver disease to provide an improvement in overall prognosis and therapy. In this review, we aim to summarize the cross-talk between heart and liver in the setting of the main pathologic conditions affecting these organs. Accordingly, we present the clinical manifestation, biochemical profiles, and histological findings of cardiogenic ischemic hepatitis and congestive hepatopathy due to acute and chronic heart failure, respectively. In addition, we discuss the main features of cardiac dysfunction in the setting of liver cirrhosis, nonalcoholic fatty liver disease, and those following liver transplantation.
New evidence suggests that non-alcoholic fatty liver disease (NAFLD) has a strong multifaceted relationship with diabetes and metabolic syndrome, and is associated with increased risk of cardiovascular events, regardless of traditional risk factors, such as hypertension, diabetes, dyslipidemia, and obesity. Given the pandemic-level rise of NAFLD—in parallel with the increasing prevalence of obesity and other components of the metabolic syndrome—and its association with poor cardiovascular outcomes, the question of how to manage NAFLD properly, in order to reduce the burden of associated incident cardiovascular events, is both timely and highly relevant. This review aims to summarize the current knowledge of the association between NAFLD and cardiovascular disease, and also to discuss possible clinical strategies for cardiovascular risk assessment, as well as the spectrum of available therapeutic strategies for the prevention and treatment of NAFLD and its downstream events.
The aim of these studies was to compare the pharmacokinetics, pharmacodynamics, counterregulatory hormone and symptom responses, as well as cognitive function during hypoglycaemia induced by s.c. injection of 0.15 IU/kg of regular human insulin (HI) and the monomeric insulin analogue [Lys(B28),Pro (B29)] (MI) in insulin-dependent-diabetic (IDDM) subjects. In these studies glucose was infused whenever needed to prevent decreases in plasma glucose below 3 mmol/l. After MI, plasma insulin increased earlier to a peak (60 vs 90 min) which was greater than after HI (294 +/- 24 vs 255 +/- 24 pmol/l), and plasma glucose decreased earlier to a 3 mmol/l plateau (60 vs 120 min) (p < 0.05). The amount of glucose infused to prevent plasma glucose falling below 3 mmol/l was approximately three times greater after MI than HI (293 +/- 26 vs 90 +/- 25 mumol.kg-1 x 60-375 min-1, p < 0.05). After MI, hepatic glucose production was more suppressed (0.7 +/- 1 vs 5.9 +/- 0.54 mumol.kg-1.min-1) and glucose utilization was less suppressed than after HI (11.6 +/- 0.65 vs 9.1 +/- 0.11 mumol.kg-1.min-1) (p < 0.05). Similarly, plasma NEFA, glycerol, and beta-OH-butyrate were more suppressed after MI than HI (p < 0.05), whereas plasma lactate increased only after MI, but not after HI. Responses of counterregulatory hormones, symptoms and deterioration in cognitive function during plasma glucose plateau of 3 mmol/l were superimposable after MI and HI (p = NS).(ABSTRACT TRUNCATED AT 250 WORDS)
