Liraglutide reduces plasma PCSK9 in patients with type 2 diabetes not treated with statins
2022
Dyslipidaemia in type 2 diabetes mellitus (T2DM), which increases cardiovascular risk, includes abnormal metabolism of low-density lipoproteins (LDL). Our group has recently shown that liraglutide increases LDL catabolism in patients with T2DM and that it reduces the expression of PCSK9 (a major inhibitor of LDL-receptor expression) in vitro and in mice. This prompted us to study the effect of liraglutide on plasma PCSK9 level in patients with T2DM.We studied prospectively 82 patients with T2DM (51 without statins, 31 with statins). Plasma PCSK9 and plasma lipids were measured before and six months after the initiation of a treatment with liraglutide at a dose of 1.2 mg/day.Plasma PCSK9 was…
Nésidioblastose traitée par pasiréotide LAR : à propos d’un cas
2021
Resume Une patiente de 56 ans, diabetique de type 2, presentait des episodes d’hypoglycemies, qui ont persiste apres arret du traitement antidiabetique. Une epreuve de jeune authentifie une hypoglycemie organique, a 0,34 g/L, insulinemie a 6 mUI/L, peptide C a 1,9 ng/mL (normes : 0,5–3,0 ng/mL) et proinsuline a 3,72, puis 4,5 pmol/L (normes : 1,28–3,84 pmol/L). Aucune lesion n’est retrouvee au scanner ou a l’echo-endoscopie. La scintigraphie a la somatostatine est negative. Ces elements font ainsi porter le diagnostic de nesidioblastose. Des traitements par diazoxide et octreotide sont successivement mis en place, sans succes. Sous pasireotide LAR, les hypoglycemies disparaissent, avec meme…
Successful Control of Hypoglycemia with Pasireotide LAR in a Patient with Inappropriate Insulin Secretion
2021
Introduction Inappropriate insulin secretion could be due to several diseases. Nesidioblastosis is characterized by diffuse hyperplasia of pancreatic beta cells, causing organic hypoglycemia. No pancreatic lesions are found on the imaging of patients with this condition. Diazoxide is used as a first-line treatment but can be poorly tolerated because of its side effects, and therapeutic failure is possible. Somatostatin analogues have limited efficacy because of their poor affinity to somatostatin (SST) receptors. Pasireotide is a somatostatin analogue with a much higher affinity to SST receptors, especially SST5, and it could thus be more efficient for treating nesidioblastosis-related hypo…
Fewer Type A personality traits in type 2 diabetes patients with diabetic foot ulcer.
2021
Abstract Aim Type A personality—characterized by time urgency, strong drive, and a need for achievement and competitiveness—has been shown to be associated with reduced mortality in patients with diabetes. However, it is not known whether a Type A personality might protect against diabetic foot ulcer (DFU). This prompted our present analysis of the association between Type A personality and DFU. Methods The Bortner Scale questionnaire was used to assess Type A personality in 386 patients with type 2 diabetes (T2D), including 104 patients also presenting with, and 282 presenting without, DFU. Additional questionnaires were used to assess perceived stress and depression. Results Type A Bortne…
Increased body fat mass reduces the association between fructosamine and glycated hemoglobin in obese type 2 diabetes patients
2021
Abstract Obesity is increasing in patients with type 2 diabetes. A possible reduced association between fructosamine and glycated hemoglobin (HbA1c) in obese individuals has been previously discussed, but this has never been specifically evaluated in type 2 diabetes, and the potential influence of body fat mass and fat distribution has never been studied. We studied 112 type 2 diabetes patients with assessment of fat mass, liver fat and fat distribution. Patients with body mass index (BMI) above the median (34.9 kg/m2), versus BMI below the median, had a correlation coefficient between fructosamine and HbA1c significantly reduced (r = 0.358 vs r = 0.765). In the whole population, fructosami…
