RESUMO

The asymptomatic phase of type 1 diabetes is recognised by the presence of beta cell autoantibodies in the absence of hyperglycaemia. We propose that an accurate description of this stage is provided by the name 'Autoimmune Beta Cell Disorder' (ABCD). Specifically, we suggest that this nomenclature and diagnosis will, in a proactive manner, shift the paradigm towards type 1 diabetes being first and foremost an immune-mediated disease and only later a metabolic disease, presaging more active therapeutic intervention in the asymptomatic stage of disease, before end-stage beta cell failure. Furthermore, we argue that accepting ABCD as a diagnosis will be critical in order to accelerate pharmaceutical, academic and public activities leading to clinical trials that could reverse beta cell autoimmunity and halt progression to symptomatic insulin-requiring type 1 diabetes. We recognize that there are both opportunities and challenges in the implementation of the ABCD concept but hope that the notion of 'asymptomatic autoimmune disease' as a disorder will be widely discussed and eventually accepted.

RESUMO

OBJECTIVE/METHODS: Barriers to continuous glucose monitoring (CGM) use continue to hamper adoption of this valuable technology for the management of diabetes. The American Association of Clinical Endocrinologists and the American College of Endocrinology convened a public consensus conference February 20, 2016, to review available CGM data and propose strategies for expanding CGM access. RESULTS: Conference participants agreed that evidence supports the benefits of CGM in type 1 diabetes and that these benefits are likely to apply whenever intensive insulin therapy is used, regardless of diabetes type. CGM is likely to reduce healthcare resource utilization for acute and chronic complications, although real-world analyses are needed to confirm potential cost savings and quality of life improvements. Ongoing technological advances have improved CGM accuracy and usability, but more innovations in human factors, data delivery, reporting, and interpretation are needed to foster expanded use. The development of a standardized data report using similar metrics across all devices would facilitate clinician and patient understanding and utilization of CGM. Expanded CGM coverage by government and private payers is an urgent need. CONCLUSION: CGM improves glycemic control, reduces hypoglycemia, and may reduce overall costs of diabetes management. Expanding CGM coverage and utilization is likely to improve the health outcomes of people with diabetes.

RESUMO

BACKGROUND AND AIM: In the context of present epidemic of childhood obesity, we aimed to find the prevalence of nonalcoholic fatty liver disease (NAFLD) and metabolic syndrome (MS) in a cohort of obese children. METHODOLOGY: Retrospective chart analysis of 700 obese children was done for their anthropometric and biochemical investigations. RESULTS: Some 15.4% (9.8% girls, 22% boys) subjects had NAFLD (ALT > 40 IU/L) after excluding other identifiable causes of liver dysfunction. Age, weight, TG, fasting serum insulin and HOMA-IR levels were higher in children with NAFLD. Twenty-eight percent children had MS. Children with NAFLD had an odds ratio of 2.65 for having MS (boys 4.6, girls 1.7). The prevalence of MS increased with age 5-9 years (21%), 10-16 years (30%), 17-20 years (35%). CONCLUSION: Given high prevalence of NAFLD and MS in obese children, childhood obesity should be seriously considered as a disease and not just a cosmetic issue.

RESUMO

AIMS: Increased adiposity is a risk factor for suboptimal diabetes control and cardiovascular disease (CVD) complications. Our goal was to identify modifiable behavioral characteristics of overweight and obese pediatric patients with type 1 diabetes mellitus (T1DM) who achieve optimal glycemic control and to evaluate their CVD risk compared to lean patients. Our hypothesis was that optimally controlled obese and overweight participants require more total daily insulin and are at higher CVD risk compared to optimally controlled lean participants. METHODS: We analyzed a cohort of 9263 participants with T1DM aged <21 years in the T1D Exchange Registry. Optimal diabetes control was defined as HbA1c ≤ 7.5% (58 mmol/mol). We compared factors that influence glycemic control in lean, overweight and obese participants with optimal vs. suboptimal control, using logistic regression. RESULTS: Age, race, overweight status, continuous subcutaneous insulin infusion (CSII) and continuous glucose monitoring (CGM) use were important variables influencing glycemic control. In the optimally controlled cohort, 27% of participants were overweight or obese versus 30% in the suboptimally controlled cohort (P < 0.001). Overweight and obese participants with optimal control were not significantly different from lean participants in terms of CSII use, total daily insulin dosage per kg of bodyweight, glucose checks per day, boluses with bedtime snack, use of CGM, but had higher LDL cholesterol and triglycerides, and lower HDL cholesterol (P < 0.05). CONCLUSIONS: There were no differences in modifiable behavioral characteristics between the obese, overweight and lean optimally controlled participants. However, predictors of cardiovascular disease were higher in the overweight and obese group.

RESUMO

CONTEXT: Although GH has been used to treat short stature in GH deficiency (GHD) and other conditions for more than 40 yr, criteria for satisfactorily defining targets for GH responsiveness have never been developed. OBJECTIVE: The objective of this study was to present the first-year growth expressed as height velocity (HV) for prepubertal boys and girls with idiopathic GHD, organic GHD, idiopathic short stature, or Turner syndrome from Genentech's National Cooperative Growth Study to derive age-specific targets for GH responsiveness for each etiology and gender. DESIGN AND POPULATION: Using data from the National Cooperative Growth Study, we constructed curves of response to GH during the first year of treatment with standard daily doses in naive-to-treatment prepubertal children with idiopathic GHD (2323 males, 842 females), organic GHD (582 males, 387 females), idiopathic short stature (1392 males, 465 females), or Turner syndrome (1367 females). MAIN OUTCOME MEASURE: For each category, mean pretreatment and mean +/-1 and +/-2 sd for the first-year HV on GH were assessed. Mean and mean +/- 1 sd for HV were plotted vs. age at baseline (initiation of GH treatment) and compared with mean pretreatment HV. RESULTS: HV plots for each category as a factor of age at baseline are presented. Mean - 2 sd HV plots approximated the pretreatment HV. CONCLUSION: Using baseline age- and gender-specific targets will assist clinicians in assessing a patient's first-year growth response. We propose that HV below the mean - 1 sd on these plots be considered a "poor" response. These curves may be used to identify patients who may benefit from GH dose adjustment, to assess compliance issues, or to challenge the original diagnosis.

RESUMO

OBJECTIVE: Recent studies have shown a broad prevalence of vitamin D deficiency in adults. Serum 25-hydroxyvitamin D (25-OHD) levels were reported to be inversely related to body mass index (BMI) and body fat content and correlated directly with hypertension, degree of insulin resistance and progression to diabetes mellitus. We sought to determine the prevalence of vitamin D insufficiency and markers of metabolic syndrome in an obese pediatric population. METHODS: Charts of 217 obese (weight >95th percentile for age and sex) children (118 females, 99 males; mean BMI 32.2 +/- 6.4 kg/m2; mean age 12.9 2 5.5; age range 7-18 years) who had received a standard physical examination at the pediatric endocrine clinic of the Infants and Children's Hospital of Brooklyn at Maimonides, Brooklyn, NY, were retrospectively analyzed. Data obtained included age, sex, weight, BMI, height and systolic and diastolic blood pressure. The routine bloodwork panel for obesity at our pediatric endocrine facility includes fasting 25-OHD, total cholesterol, high density lipoprotein-cholesterol (HDL-C), low density lipoprotein-cholesterol (LDL-C), triglycerides, ALT, AST, thyroid stimulating hormone (TSH), total T4, and insulin and glucose. Insulin sensitivity as calculated by quantitative insulin-sensitivity check index (QUICKI = 1/[log(I0) + log(G0)], where I0 is fasting insulin and G0 is fasting glucose) was computed following the visit. RESULTS: Overall, 55.2% of patients were vitamin D insufficient (25-OHD <20 ng/ml). Severely low vitamin D levels (25-OHD < or =10 ng/ml) were seen in 21.6% of 217 patients, which represents almost half of the insufficient group. In the 25-OHD <20 ng/ml group age, BMI, and SBP were significantly higher than in the 25-OHD 220 ng/ml group, while QUICKI (<0.35 is consistent with insulin resistance) was borderline low in the <20 ng/ml group. HDL-C was significantly lower in the 25-OHD < or =10 ng/ml group. The 25-OHD levels correlated negatively with BMI and positively with HDL-C. No other findings were significant. CONCLUSION: More than half of the obese children had vitamin D levels <20 ng/ml with equal gender distribution. Vitamin D insufficiency was associated with increased age, BMI, and SBP, and decreased HDL-C.

RESUMO

UNLABELLED: Alström syndrome (AS) is an autosomal recessive disorder characterized by progressive pigmentary retinopathy, sensorineural hearing loss, fatty liver infiltration, obesity, insulin resistance and early-onset type 2 diabetes mellitus (DM2). Early onset of insulin resistance and DM2 are key components of this syndrome. AIM: To study the effect of early initiation of the insulin sensitizer metformin combined with rosiglitazone in a patient with AS with impaired glucose tolerance. PATIENT: An 8 year-old boy with AS presented with acanthosis nigricans and insulin resistance at the age of 6 years. He had progressive excessive weight gain from 9 months of age. By the age of 1 year he developed photosensitivity, blindness and nystagmus. At the age of 5.5 years, his body mass index (BMI) was above the 95th percentile. He developed impaired glucose tolerance at 6 years of age and treatment with metformin was initiated. After 8 months of treatment with metformin he developed DM2. The dose of metformin was increased, and rosiglitazone added. METHODS: A 2-hour oral glucose tolerance test (OGTT) and a rapid intravenous glucose tolerance test (IVGTT) were performed before treatment was initiated, after treatment with metformin and at the end of 1 year of combination therapy with metformin and rosiglitazone to calculate quantitative insulin sensitivity check index (QUICKI) and acute insulin response (AIR). For mutation analysis, all exons and splice site sequences of the ALMS1 gene were amplified and sequenced. RESULTS: Metformin treatment alone at the stage of impaired glucose tolerance did not prevent progression to DM2. However, metformin at a higher dose and in combination with rosiglitazone resulted in improvement of pancreatic beta-cell function, shown by markedly improved first-phase insulin response to glucose measured by AIR. The patient was found to have two heterozygous nonsense mutations in ALMS1, 8008 C-->T Ter, R2670X, and 11449 C-->T Ter, Q3817X. These alterations cause premature stops and result in a truncated ALMS1 protein. CONCLUSION: We suggest that early initiation of combined therapy comprising a high dose of metformin plus rosiglitazone may be valuable in managing insulin resistance and DM2 in children with AS.

RESUMO

OBJECTIVE: To identify and define clinically meaningful type 1 diabetes outcomes beyond hemoglobin A1c (HbA1c) based upon a review of the evidence, consensus from clinical experts, and input from researchers, people with type 1 diabetes, and industry. Priority outcomes include hypoglycemia, hyperglycemia, time in range, diabetic ketoacidosis (DKA), and patient-reported outcomes (PROs). While priority outcomes for type 1 and type 2 diabetes may overlap, type 1 diabetes was the focus of this work. RESEARCH AND METHODS: A Steering Committee-comprising representatives from the American Association of Clinical Endocrinologists, the American Association of Diabetes Educators, the American Diabetes Association, the Endocrine Society, JDRF International, The Leona M. and Harry B. Helmsley Charitable Trust, the Pediatric Endocrine Society, and the T1D Exchange-was the decision-making body for the Type 1 Diabetes Outcomes Program. Their work was informed by input from researchers, industry, and people with diabetes through Advisory Committees representing each stakeholder group. Stakeholder surveys were used to identify priority outcomes. The outcomes prioritized in the surveys were hypoglycemia, hyperglycemia, time in range, DKA, and PROs. To develop consensus on the definitions of these outcomes, the Steering Committee relied on published evidence, their clinical expertise, and feedback from the Advisory Committees. RESULTS: The Steering Committee developed definitions for hypoglycemia, hyperglycemia, time in range, and DKA in type 1 diabetes. The definitions reflect their assessment of the outcome's short- and long-term clinical impact on people with type 1 diabetes. Knowledge gaps to be addressed by future research were identified. The Steering Committee discussed PROs and concluded that further type 1 diabetes-specific development is needed. CONCLUSIONS: The Steering Committee recommends use of the defined clinically meaningful outcomes beyond HbA1c in the research, development, and evaluation of type 1 diabetes therapies.

RESUMO

CONTEXT: LHX3 encodes LIM homeodomain class transcription factors with important roles in pituitary and nervous system development. The only previous report of LHX3 mutations described patients with two types of recessive mutations displaying combined pituitary hormone deficiency coupled with neck rigidity. OBJECTIVE: We report a patient presenting a unique phenotype associated with a novel mutation in the LHX3 gene. PATIENT: We report a 6-yr, 9-month-old boy born from a consanguineous relationship who presented shortly after birth with cyanosis, feeding difficulty, persistent jaundice, micropenis, and poor weight gain and growth rate. Laboratory data, including an undetectable TSH, low free T4, low IGF-I and IGF binding protein-3, prolactin deficiency, and LH and FSH deficiency were consistent with hypopituitarism. A rigid cervical spine leading to limited head rotation was noticed on follow-up examination. Magnetic resonance imaging revealed an apparently structurally normal cervical spine and a postcontrast hypointense lesion in the anterior pituitary. RESULTS: Analysis of the LHX3 gene revealed homozygosity for a novel single-base-pair deletion in exon 2. This mutation leads to a frame shift predicted to result in the production of short, inactive LHX3 proteins. The results of in vitro translation experiments are consistent with this prediction. The parents of the patients are heterozygotes, indicating a recessive mode of action for the deletion allele. CONCLUSIONS: The presence of a hypointense pituitary lesion and other clinical findings broadens the phenotype associated with LHX3 gene mutation.

RESUMO

BACKGROUND: This study was designed to test the feasibility and efficacy of continuous subcutaneous insulin infusion (CSII) being instituted within 1 month of diagnosis of type 1 diabetes mellitus (T1DM). METHODS: Twenty-eight consecutive patients with newly diagnosed T1DM with a mean age of 12.1 +/- 6.2 years were placed on CSII, as early as within 1 day of their diagnosis. All accepted CSII when offered it, and none elected to discontinue CSII after follow-up periods of up to 3 years. RESULTS: Hemoglobin A1c levels declined from an initial mean of 10.5 +/- 2.4% to between 6.5% and 7.4% over the next 18 months, at a mean insulin requirement of 0.33 units/kg/day at 3 months, which gradually rose to 0.58 units/kg/day by 18 months. Endogenous insulin secretion, measured by C-peptide values, remained stable during the first 12 months after diagnosis. There was no significant weight gain for the duration of the study (20.7 kg/m(2) vs. a peak of 22.1 kg/m(2) at 12 months, P = 0.54). CONCLUSIONS: The study provided a positive experience with CSII as the initial insulin replacement therapy in newly diagnosed patients with T1DM with excellent clinical outcomes and apparent prolongations of the honeymoon period. It remains to be proven by random patient assignment whether endogenous insulin secretion is better preserved with CSII as an initial ongoing treatment modality and whether long-term complications are reduced by this approach.

RESUMO

BACKGROUND: The role of growth hormone (GH) in obesity is controversial. Childhood obesity is characterized by reduced GH secretion. Low, high and normal serum insulin-like growth factor-I (IGF-I) levels have been described in obese children in the face of low GH secretion. There is conflicting information on the interaction of GH and obesity upon components of the GH-IGF-I-insulin-like growth factor binding proteins (IGFBPs) system and its relationship to cardiovascular risk factors. OBJECTIVE: This review highlights the role of GH modulating cardiovascular risk factors, including lipid levels, inflammatory markers, cardiac and endothelial function in children and adolescents with obesity and insulin resistance. CONCLUSIONS: The interplay between GH secretion, NO production, IGF-I, IGFBP-1, and IGFBP-3 levels, lipid profile, insulin sensitivity and the degree of visceral obesity necessitates further study. These metabolic parameters may be useful markers of premature atherosclerosis in children with obesity. Further studies should address the question of optimal dose and duration of GH therapy in non-GH deficient obese patients with metabolic disturbances at risk for premature atherosclerosis.

RESUMO

Congenital lipoid adrenal hyperplasia (lipoid CAH) is an autosomal recessive disorder characterized by severe adrenal insufficiency and male sex reversal. Lipoid CAH is caused by mutations in two proteins that are essential for all steroid biosynthesis, the steroidogenic acute regulatory (StAR) protein and cytochrome P450scc. In this review, we discuss the clinical presentation and mechanisms behind the pathology of this fatal disorder.

RESUMO

Much progress has been made in diabetes treatments since the first dose of insulin was administered in 1921. However, a truly transformational moment in diabetes care occurred when urine testing gave way to capillary blood home glucose monitoring. As improvements were made to these devices, continuous glucose monitoring (CGM) was introduced. The advantages of experiential learnings gleaned from seeing continuous real-time data have been borne out in numerous peer-reviewed journals. Limitations to use of CGM include patient's level of numeracy and literacy, development of alarm fatigue, interfering substances leading to erroneous readings, high rates of discontinuation, and poor reimbursement.

RESUMO

OBJECTIVE: This study aims to compare the effectiveness of insulin glargine 300 U/mL (Gla-300) with its accompanying patient support program with that of other basal insulin and available patient support programs in patients with type 2 diabetes (T2D) in a real-world setting in terms of achieving HEDIS (Healthcare Effectiveness Data and Information Set) individualized glycemic targets without documented symptomatic hypoglycemia. METHODS: Achieve Control is a US-based, multicenter, randomized, open-label, active-controlled, parallel group pragmatic Phase IV trial in insulin-naïve patients with T2D uncontrolled on ≥2 oral antidiabetes drugs (OAD) and/or glucagon-like peptide-1 receptor antagonists (GLP-1 RA). Inclusion criteria include a diagnosis of T2D, age ≥18 years, and glycated hemoglobin (HbA1c) between 8.0% and 11.0%. Patients will be assigned to either the Gla-300 or other basal insulin group. The primary end point is the proportion of patients achieving HEDIS HbA1c targets (<8.0% [64 mmol/mol] in patients with comorbidities or aged ≥65 years; <7.0% [58 mmol/mol] in all other patients) without occurrence of symptomatic hypoglycemia (blood glucose ≤70 mg/dL) from baseline to 6 months. Secondary end points include rates of documented symptomatic nocturnal hypoglycemia and severe hypoglycemia; change from baseline in HbA1c, fasting glucose, and body weight; treatment persistence; patient-reported outcomes; and healthcare resource utilization. Planned enrollment is 3270 patients across approximately 400 clinical sites. CONCLUSION: Pragmatic clinical trials offer the potential to assess comparative effectiveness in broadly based patient populations receiving care (with or without a corresponding educational support program) in real-world clinical settings. The results of Achieve Control should elucidate the benefits of management of T2D with Gla-300 versus other basal insulins in terms of patient outcomes, experiences, and perceptions, and its impact on healthcare resource utilization and cost. CLINICAL TRIAL REGISTRATION: www.clinicaltrials.gov identifier is NCT02451137.

RESUMO

CONTEXT: Mutations in the gene encoding steroidogenic acute regulatory protein (StAR) are the most common cause of lipoid congenital adrenal hyperplasia (lipoid CAH), a disorder characterized by adrenal insufficiency and deficient gonadal steroid synthesis, resulting in female external genitalia in both genetic sexes. OBJECTIVE: We describe three new cases of lipoid CAH caused by novel mutations in the StAR gene. PATIENTS: An XY subject of Yemeni descent presented with adrenal insufficiency and severe undervirilization. Magnetic resonance imaging (MRI) of the brain showed enlarged subarachnoid spaces consistent with frontal and temporal atrophy. Two XX siblings of Palestinian descent presented with neonatal adrenal insufficiency. One had a borderline intelligence quotient and features of attention deficit hyperactivity disorder. MRI showed areas of supratentorial white matter lesions. In her sister, MRI revealed a Chiari-I malformation. RESULTS: The XY subject was found to have a missense mutation (R182C). Both XX siblings had a dinucleotide deletion at nucleotides 327-328 that induces a frame shift that truncates the StAR protein after 68 amino acids. CONCLUSIONS: These cases broaden the spectrum of known StAR mutations and suggest that disorders of central nervous system development may arise because of StAR deficiency and/or the metabolic consequences of neonatal adrenal deficiency.

RESUMO

In March 2004 a group of 65 physicians and other health professionals representing nine countries on four continents convened in Israel to discuss the widespread public health crisis in childhood obesity. Their aim was to explore the available evidence and develop a consensus on the way forward. The process was rigorous, although time and resources did not permit the development of formal evidence-based guidelines. In the months before meeting, participants were allocated to seven groups covering prevalence, causes, risks, prevention, diagnosis, treatment, and psychology. Through electronic communication each group selected the key issues for their area, searched the literature, and developed a draft document. Over the 3-d meeting, these papers were debated and finalized by each group before presenting to the full group for further discussion and agreement. In developing a consensus statement, this international group has presented the evidence, developed recommendations, and provided a platform aimed toward future corrective action and ongoing debate in the international community.

RESUMO

BACKGROUND: Obesity and insulin resistance are increasingly common problems in children. Tumor necrosis factor-alpha (TNF-alpha) has important effects on lipid and glucose metabolism. This effect may be mediated through soluble TNF-alpha receptor 2 (sTNFR2). OBJECTIVE: To investigate the relationship between insulin resistance and the TNF-alpha system in childhood obesity. CHILDREN AND METHODS: Twenty-one obese and six non-obese children were studied. Body mass index (BMI) z-scores, percent body fat (PBF) and waist to hip ratio (WHR) were determined. Fasting serum levels of total cholesterol, HDL-cholesterol, LDL-cholesterol, TNF-alpha and sTNFR2 were measured. A standard 2-hour oral glucose tolerance test (dose of glucose: 1.75 g/kg, max. 75 g) was done. Insulin resistance (IR) was estimated by fasting plasma insulin, plasma insulin at 120 min, homeostasis model assessment (HOMA) and insulin area under the curve (AUC) from OGTT. Insulin sensitivity was estimated by oral glucose insulin sensitivity (OGIS120). RESULTS: Among the obese participants, one child (5.2%) was found to have diabetes mellitus and four others (21.1%) impaired glucose tolerance (IGT). Obese children had significantly elevated sTNFR2 levels. Furthermore, the group of obese children with IGT and the patient with newly diagnosed diabetes mellitus together (n = 5) had significantly higher levels of serum sTNFR2 (2,865+/-320 pg/ml) than the rest of the obese (2,460+/-352 pg/ml; p = 0.016) or lean (1,969+/-362 pg/ml; p = 0.014) children. Serum sTNFR2 levels correlated positively with insulin AUC, HOMA IR, fasting plasma insulin, plasma insulin at 120 min, total cholesterol and LDL/ HDL ratio, and negatively with OGIS120. Multiple regression analysis revealed that age, WHR, sTNFR2 and LDL predicted 81% of the variability in glucose at 120 min. CONCLUSION: sTNFR2 is a candidate marker of insulin resistance and glucose intolerance.

RESUMO

Graves' disease in pregnancy is a rare condition that directly affects neonatal thyroid function. We describe three newborns born to mothers with Graves' disease and discuss differences in outcomes and management. The first infant presented with a goiter at birth but was euthyroid and did not require therapy. The second infant presented with thyroid storm and the third infant present with neonatal hyperthyroidism, and both required treatment with antithyroid drugs. There was documented elevation of maternal and infant thyroid stimulating hormone immunoglobulin (TSI) levels in all three infants. Management of an infant born to a mother with Graves' disease should include monitoring of both maternal and neonatal thyroid function, and maternal TSI levels during pregnancy. Treatment may be needed if the newborn is symptomatic. With clearance of maternal antibodies and antithyroid drugs, manifestations of abnormal thyroid function in the neonate gradually regress, including eventual resolution of a goiter, if initially present.

RESUMO

BACKGROUND: Oxidative stress is a detrimental feature of diabetes implicated in the progression of the disease and its complications. The relationship between insulin therapy and oxidative stress is complex. This study tested the hypothesis that improved glucose control, rather than insulin dose, is central to reduced oxidative stress in patients with type 2 diabetes following continuous subcutaneous insulin infusion (CSII). METHODS: In this 16-week, multicenter study, 54 CSII-naïve patients with type 2 diabetes (age 57 ± 10 years, HbA1c 69 ± 15 mmol/mol [8.5 ± 1.4%], diabetes duration 13 ± 6 years) treated with either oral antidiabetic agents (OAD) alone (n = 17), basal insulin ± OAD (n = 17), or multiple daily injections (MDI) ± OAD (n = 20) were the evaluable group. Diabetes medications except metformin were discontinued, and 16 weeks of CSII was initiated. Insulin dose was titrated to achieve optimal glycemic control. A plasma marker of oxidative stress relevant to cardiovascular disease (oxidized low density lipoprotein [ox-LDL]) was assessed at baseline and week 16. RESULTS: CSII improved glycemic control (HbA1c -13 ± 2 mmol/mol [-1.2 ± 0.2%]; fasting glucose -36.6 ± 8.4 mg/dL; mean glucose excursion -23.2 ± 6.5 mg/dL, mean ± SE; all P < .001) and reduced ox-LDL (-10.5%; P < .05). The antioxidant effect was cohort-independent (P > .05), but was significantly more pronounced in patients on statins (P = .019). The effect of CSII was more closely correlated to improvements in glucose excursion (P = .013) than to insulin dose (P > .05) or reduction in HbA1c (P > .05). CONCLUSIONS: CSII induces depression of plasma ox-LDL associated with change in glucose control, rather than with change in insulin dose. The effect is augmented in patients receiving statins.
