We tested the hypothesis that common genetic variability of β cell mass and/or function genes may influence β cell functional mass in type 2 diabetes (T2DM). We studied 590 drug-naive GAD-negative patients with newly diagnosed T2DM (age: median=60.0 yrs; I.Q. range: 52–66; BMI: 29.3 kg/m2; 26.5–32.9). β cell functional mass was assessed by state-of-art mathematical modeling of glucose/C-peptide curves during a 240’ frequently sampled O...

Objective: Bariatric surgery has a marked effect on diabetes risk in the obese. The aim of this study was to evaluate weight-loss independent effects of gastric bypass on glucose and insulin levels over 10-years of follow-up.Research design and methods: A total of 2010 obese individuals received bariatric surgery in the Swedish Obese Subjects (SOS) study (376 patients underwent non-adjustable or adjustable banding, 1369 underwent vertical banded gastropl...

Objective: To determine if autologous nonmyeloablative hematopoietic stem cell transplantation (AHSCT) was worthwhile to do in type 1 diabetes adolescents with diabetic ketoacidosis at diagnosis.Research Design and Methods: We enrolled 28 type 1 diabetes patients aged 14–30 years in a prospective AHSCT phase II clinical trial. Hematopoietic stem cells were harvested from the peripheral blood following a pretreatment consisting of a combination of cy...

Aim: Following the general concern regarding the association between various diabetes treatments and cancer risk, the present study evaluated the cancer specific mortality in adult insulin-treated diabetes patients.Materials and methods: All diabetes patients residing in a major urban area, aged over 40 years and receiving insulin treatment were included at the moment of their first diabetes outpatient visit from 01/01/2001 to 12/31/2008. A total of 1136...

Background: Toll-like receptors (TLRS) are a class of proteins that play a key role in the innate immune system. They are single, membrane, non catalytic receptors which are expressed in multiple tissues predominantely cells of the innate immune system especially monocytes. So, they play a critical role in the regulation of immune function and inflammation.Aim of our work: To study the expression of toll-like receptor 2 and 4 on monocytes in T1DM patient...

Introduction: Long-standing type 2 diabetes (DM) is associated with brain atrophy. In this prospective study we examined the impact of glycaemic status on total brain volume in an elderly cohort.Methods/Design: Two-year follow-up study of a population-derived cohort of non-demented community-dwelling adults aged 70–90 years (Sydney Memory and Aging Study). Prospective MRI and metabolic data were available in 312 of the 542 participants who had a MRI...
