Long-term efficacy of rosiglitazone in nonalcoholic steatohepatitis: results of the fatty liver improvement by rosiglitazone therapy (FLIRT 2) extension trial.

UNLABELLED: Short-term trials of glitazones in nonalcoholic steatohepatitis (NASH) yielded controversial histological results. Longer treatment might result in additional improvement. After a 1-year randomized trial, 53 patients underwent a control liver biopsy and were enrolled in an open-label extension trial of rosiglitazone (RSG), 8 mg/day for 2 additional years. In all, 44 completed the extension phase including 40 with a third liver biopsy. Of these, 22 received placebo (PLB) in the randomized phase (PLB-RSG), and 18 RSG (RSG-RSG). During the 2-year extension phase serum insulin decreased by 26%, homeostasis model assessment (HOMA) by 30%, and alanine aminotransferase (ALT) by 24%. However, there was no significant change in the mean NASH activity score (NAS) (3.8 +/- 2.11 versus 3.68 +/- 1.8), ballooning score, fibrosis stage (1.76 +/- 1.18 versus 1.85 +/- 1.19), or area of fibrosis by micromorphometry (4.43% +/- 0.68 to 5.54% +/- 0.68). In the PLB-RSG group steatosis significantly decreased after 2 years of RSG (median decrease of 15%); in the RSG-RSG group, after an initial decline in the first year of 20%, 2 additional years of RSG did not result in further improvement. Likewise, there was no improvement in the NAS score, ballooning, intralobular inflammation, fibrosis stage, or area of fibrosis with 2 additional years of RSG in the RSG-RSG group. CONCLUSION: Rosiglitazone has a substantial antisteatogenic effect in the first year of treatment without additional benefit with longer therapy despite a maintained effect on insulin sensitivity and transaminase levels. This suggests that improving insulin sensitivity might not be sufficient in NASH and that additional targets of therapy for liver injury should be explored.

Transition of young adults with endocrine and metabolic diseases: the 'TRANSEND' cohort.

OBJECTIVE: The transition from paediatric to adult medicine involves risks of poor patient outcomes and of significant losses of patients to follow up. The research aimed to analyse the implementation in an initial cohort of patients of a new programme of transition to adult care based on a case management approach. DESIGN: A longitudinal study of the case management approach to transition, initiated in a university hospital in France in September 2016. METHODS: Patients with the endocrine or metabolic disease diagnosed during childhood and transferred to adult care were included. The transition programme includes three steps based on case management: liaising with paediatric services, personalising care pathways, and liaising with structures outside the hospital (general practitioners, agencies in the educational and social sector). RESULTS: The cohort included 500 patients, with malignant brain tumour (n = 56 (11%)), obesity (n = 55 (11%)), type 1 diabetes (n = 54 (11%)), or other disease (n = 335 (67%)). Their median age at transfer was 19, and the sex ratio was 0.5. At median 21 months of follow-up, 439 (88%) had a regular follow-up in or outside the hospital, 47 (9%) had irregular follow-up (absence at the last appointment or no appointment scheduled within the time recommended), 4 had stopped care on doctor's advice, 4 had died, 3 had moved, and 3 had refused care. The programme involved 9615 case management actions; 7% of patients required more than 50 actions. Patients requiring most support were usually those affected by a rare genetic form of obesity. CONCLUSIONS: Case managers successfully addressed the complex needs of patients. Over time, the cohort will provide unprecedented long-term outcome results for patients with various conditions who experienced this form of transition.

Inactive matrix gla protein plasma levels are associated with peripheral neuropathy in Type 2 diabetes.

AIMS/HYPOTHESIS: Diabetic peripheral neuropathy is a frequent and severe complication of diabetes. As Matrix-gla-protein (MGP) is expressed in several components of the nervous system and is involved in some neurological disease, MGP could play a role in peripheral nervous system homeostasis. The aim of this study was to evaluate factors associated with sensitive diabetic neuropathy in Type 2 Diabetes, and, in particular, dephospho-uncarboxylated MGP (dp-ucMGP), the inactive form of MGP. METHODS: 198 patients with Type 2 Diabetes were included. Presence of sensitive diabetic neuropathy was defined by a neuropathy disability score (NDS) ≥6. Plasma levels of dp-ucMGP were measured by ELISA. RESULTS: In this cohort, the mean age was 64+/-8.4 years old, and 80% of patients were men. Peripheral neuropathy was present in 15.7% of the patients and was significantly associated (r = 0.51, p<0.0001) with dp-ucMGP levels (ß = -0.26, p = 0.045) after integrating effects of height (ß = -0.38, p = 0.01), insulin treatment (ß = 0.42, p = 0.002), retinopathy treated by laser (ß = 0.26, p = 0.02), and total cholesterol levels (ß = 0.3, p = 0.03) by multivariable analysis. CONCLUSIONS: The association between diabetic neuropathy and the inactive form of MGP suggests the existence of new pathophysiological pathways to explore. Further studies are needed to determine if dp-ucMGP may be used as a biomarker of sensitive neuropathy. Since dp-ucMGP is a marker of poor vitamin K status, clinical studies are warranted to explore the potential protective effect of high vitamin K intake on diabetic peripheral neuropathy.

Insulin Pump Combined with Flash Glucose Monitoring: A Therapeutic Option to Improve Glycemic Control in Severely Nonadherent Patients with Type 1 Diabetes.

Some patients with type 1 diabetes (T1D) are severely noncompliant; they rarely perform self-blood glucose measures and miss insulin injections. Their HbA1c is far above the target rate. Current guidelines do not recommend starting treatment with an insulin pump (continuous subcutaneous insulin infusion [CSII]) for these persons. The aim of this study was to determine whether a CSII associated with a flash glucose monitoring (FGM) device could reduce HbA1c without increasing the risk of acute events, diabetic ketoacidosis (DKA) and severe hypoglycemia (SH), in these patients. We conducted a 6-month nonrandomized, pilot prospective study. Patients with T1D on multiple daily injections who performed less than two self-blood glucose tests/day and had an HbA1c >9% were equipped with CSII and an FGM device. The primary composite endpoint was defined by a change in HbA1c ≥1% without any episode of DKA or SH during 6 months. Change in mean HbA1c, weight, treatment satisfaction, frequency of minor hypoglycemia, and ketoacidosis were secondary endpoints. Nineteen adults were included. Median (Q1-Q3) HbA1c at baseline was 10.8 (10.3-13.0), 14 participants did not perform any self-monitoring and 5 performed maximum two tests daily. Twelve participants (63%) (95% confidence interval 41%-81%) met the primary composite endpoint. Seventeen patients completed the study. HbA1c decreased by 2% (1.0-3.3) (P < 0.001), and satisfaction with treatment significantly improved. Three participants experienced SH and one a DKA, versus, respectively, five and eight in the year preceding the study. Participants scanned the sensor 4 (3-6) times per day and injected 3 (2.7-4.1) boluses per day. Weight increased significantly. An association of an insulin pump with an FGM device can be an effective and safe therapeutic option in severely nonadherent and noncompliant patients with high HbA1c.

Serum concentration and vascular expression of adiponectin are differentially associated with the diabetic calcifying peripheral arteriopathy.

BACKGROUND: Medial calcification in diabetes contributes to the arterial occlusive process occurring below the knee level. Adiponectin is an adipokine with atheroprotective properties and possible protective role against arterial calcification. The aim of the study was to investigate, in type 2 diabetes, the link between vascular expression and serum concentration of adiponectin and (1) peripheral arterial calcification and (2) lower limb occlusive arterial disease. METHODS: Scoring of peripheral vascular calcification and peripheral arterial occlusive disease, using CT-scan and color-duplex ultrasonography respectively, were conducted and explored in relation to serum adiponectin level in a cross sectional study of 197 patients with type 2 diabetes. Vascular adiponectin expression in the arterial wall of diabetic patients with and without medial calcification was evaluated by immunohistochemistry. RESULTS: Peripheral arterial calcification score was higher in patients with the highest adiponectin concentration. In a multivariate logistic regression analysis, an increase of 1 µg/mL of adiponectin was associated with a 22% increase of arterial calcification (adjusted OR = 1.22; 95% CI 1.03-1.44; p = 0.02). Arterial occlusive score was also higher in patients with adiponectin concentration > median (2.8 ± 4.8 vs 4.2 ± 5.7, p = 0.034). Immunohistochemical analyses showed a strong and specific staining of adiponectin in smooth muscle cells in calcified arteries, with a more pronounced expression of adiponectin in early stages of medial calcification. CONCLUSIONS: Peripheral arterial calcification is positively associated with circulating adiponectin levels in patients with type 2 diabetes, but vascular adiponectin expression is already observed at early stages of calcification. Adiponectin secretion could be a compensatory mechanism against the calcification process.Trial registration DIACART NCT number: NCT02431234. Registered 30 April 2015.

Diabetes Mellitus, Extreme Insulin Resistance, and Hypothalamic-Pituitary Langerhans Cells Histiocytosis.

BACKGROUND: Langerhans Cell Histiocytosis (LCH) is a rare inflammatory neoplasm characterized by an infiltration of organs by Langerin + (CD207+) and CD1a+ histiocytes. Diabetes insipidus is a frequent manifestation of the disease, while diabetes mellitus is very rare. We report the first case of a 20-year-old man suffering from hypothalamopituitary histiocytosis and diabetes mellitus with serum anti-insulin receptor antibodies. CASE PRESENTATION: A 20-year-old patient was admitted for the evaluation of growth delay and hyperphagia. HbA1c level and fasting blood glucose were in the normal range. The diagnosis of hypothalamopituitary histiocytosis was based on histological features after biopsy of a large suprachiasmatic lesion identified on magnetic resonance imaging (MRI). Association of vinblastine and purinethol was started followed by a second-line therapy by cladribine. During the follow-up, the patient was admitted for recurrence of hyperglycemic states and extreme insulin resistance. The screening for serum anti-insulin receptor antibodies was positive. Each episode of hyperglycemia appeared to be correlated with tumoral activity and increase in serum anti-insulin receptor antibodies and appeared to be improved when the disease was controlled by chemotherapy. CONCLUSION: We report the first description of a hypothalamopituitary histiocytosis associated with serum anti-insulin receptor antibodies, extreme insulin resistance, and diabetes. Parallel evolution of glucose levels and serum anti-insulin receptor antibodies seemed to be the consequence of immune suppressive properties of cladribine.

High reported treatment satisfaction in people with type 1 diabetes switching to latest generation insulin pump regardless of previous therapy.

The effects of transition by individuals with type 1 diabetes (T1D) to more recently available continuous glucose monitoring (CGM)-enabled insulin pumps from either multiple daily insulin injections (MDI) or older insulin pumps on treatment satisfaction have not been well studied. We conducted a survey to assess treatment satisfaction among users of the Animas(®) Vibe™ insulin pump, a latest generation insulin pump (LGIP) system (CGM-enabled), after switching from MDI or earlier generation insulin pumps. Individuals with T1D from 141 centers in 5 countries and 4 language areas participated in the survey. Treatment satisfaction was assessed by the Insulin Treatment Satisfaction Questionnaire (ITSQ), which was included in a 50-item online questionnaire that also assessed preference for using the LGIP compared with previous treatment and satisfaction with key LGIP features. A total of 356 individuals, ages 12-79 years, responded to the survey: mean (SD) age 38.4 (16.1) years; diabetes duration 19.1 (13.3) years; female 59%; previously treated with MDI 58%. Overall mean (SD) ITSQ scores were high among all respondents regardless of prior treatment: 95.1 (23.2) (scale: 0-132). No differences between previous-treatment groups were seen. Most (83%) of respondents rated the LGIP to be better than their previous insulin delivery system: "much better" (65%), "a bit better" (18%) regardless of age, and 95% would recommend using the LGIP to others. Use of the Animas Vibe was associated with high treatment satisfaction and perceived as a better method of insulin delivery regardless of previous insulin therapy or age.

Effects of bed-time insulin versus pioglitazone on abdominal fat accumulation, inflammation and gene expression in adipose tissue in patients with type 2 diabetes.

AIMS/HYPOTHESIS: Intra-abdominal fat (IAF) and inflammatory markers are correlated with cardio-vascular risk. We compared the impact of bed-time insulin versus pioglitazone treatment on these parameters in type 2 diabetic (T2D) patients. METHODS: Twenty-eight T2D patients poorly controlled with metformin and sulfonylurea were randomized to receive add-on therapy with pioglitazone or bed-time NPH insulin. IAF and subcutaneous fat (SCF) content, systemic low-grade inflammation level and expression of inflammation related genes in SCF, were measured before and after 24 weeks of treatment. RESULTS: Insulin and pioglitazone resulted in a significant decrease in HbA1c (-1.6% and -1.2%, respectively) and a significant increase in total body fat mass (1+/-2.3 and 3.3+/-2.7 kg, respectively). There was no change in IAF content after both treatments whereas significant increase in SCF content was only seen after pioglitazone treatment (p<0.05 versus insulin). hsCRP level decreased after pioglitazone and ferritin level decreased after insulin treatment. No change in mRNA expression of inflammation related genes was found after either treatment. CONCLUSION/INTERPRETATION: This suggests that a 24-week treatment with pioglitazone or bed-time insulin has a similar impact on intra-abdominal fat mass and systemic low-grade inflammation.
