TRAIL and DcR1 Expressions Are Differentially Regulated in the Pancreatic Islets of STZ- versus CY-Applied NOD Mice
TNF-related apoptosis-inducing ligand (TRAIL) is an important component of the immune system. Although it is well acknowledged that it also has an important role in Type 1 Diabetes (T1D) development, this presumed role has not yet been clearly revealed. Streptozotocin (STZ) and Cyclophosphamide (CY) are frequently used agents for establishment or acceleration of T1D disease in experimental models, including the non-obese diabetic (NOD) mice. Although such disease models are very suitable for diabetes research, different expression patterns for various T1D-related molecules may be expected, depending on the action mechanism of the applied agent. We accelerated diabetes in female NOD mice using STZ or CY and analyzed the expression profiles of TRAIL ligand and receptors throughout disease development. TRAIL ligand expression followed a completely different pattern in STZ- versus CY-accelerated disease, displaying a prominent increase in the former, while appearing at reduced levels in the latter. Decoy receptor 1 (DcR1) expression also increased significantly in the pancreatic islets in STZ-induced disease. Specific increases observed in TRAIL ligand and DcR1 expressions may be part of a defensive strategy of the beta islets against the infiltrating leukocytes, while the immune-suppressive agent CY may partly hold down this defense, contributing further to diabetes development
Insulin degludec improves long-term glycaemic control similarly to insulin glargine but with fewer hypoglycaemic episodes in patients with advanced type 2 diabetes on basal-bolus insulin therapy.
The aim of the present study was to compare the long-term safety and efficacy of insulin degludec with those of insulin glargine in patients with advanced type 2 diabetes (T2D) over 78 weeks (the 52-week main trial and a 26-week extension). Patients were randomized to once-daily insulin degludec or insulin glargine, with mealtime insulin aspart ± metformin ± pioglitazone, and titrated to pre-breakfast plasma glucose values of 3.9-4.9 mmol/l (70-88 mg/dl). After 78 weeks, the overall rate of hypoglycaemia was 24% lower (p = 0.011) and the rate of nocturnal hypoglycaemia was 31% lower (p = 0.016) with insulin degludec in the extension trial set, while both groups of patients achieved similar glycaemic control. Rates of adverse events and total insulin doses were similar for both groups in the safety analysis set. During 18 months of treatment, insulin degludec + mealtime insulin aspart ± oral antidiabetic drugs in patients with T2D improves glycaemic control similarly, but confers lower risks of overall and nocturnal hypoglycaemia than with insulin glargine treatment

Subcutaneous NPH Insulin for Severe Hypertriglyceridemia in a Pregnant Patient with Type V Hyperlipoproteinemia: a Case Report
An increase in triglyceride levels in familial hyperlipidemia during pregnancy has been reported. Severe hypertriglyceridemia can lead to complications such as acute pancreatitis, preeclampsia, maternal and fetal complications. Because of the teratogenic effects associated with fibrate therapy in pregnancy, alternative treatment strategies such as insulin as a rapid and potent activator of lipoprotein lipase are required during pregnancy. We report a case of hypertriglyceridemia in a 33-year-old pregnant woman in whom treatment with merely single one time administration of Neutral Protamine Hagedorn insulin was accompanied by a reduction in the serum triglyceride level; to the best of our knowledge, this has never been reported in the literature. Her triglyceride level was 3616 mg/dL before insulin treatment and 1246 mg/dL after insulin treatment. Although this regimen was used safely and effectively in our patient, comprehensive studies are required to evaluate the effectiveness and safety of subcutaneously intermediate-acting Neutral Protamine Hagedorn insulin for the treatment of severe hypertriglyceridemia in non-diabetic pregnant women
Electrophysiologic evaluation of cremasteric reflex in experimental orchitis
Soyer, Tutku/0000-0003-1505-6042WOS: 000327254600027PubMed: 23660491Aim: Absent cremasteric reflex (CR) is a well known but not reliable sign of testicular torsion. We hypothesized that CR can also be altered in other causes of acute scrotum in children. An experimental study was performed to evaluate the clinical and electrophysiological features of CR in orchitis. Method: Eighteen Wistar albino rats were allocated into three groups: control (CG), sham (SG) and orchitis (OG). In CG, after anesthetization with ketamine hydrochloride, the medial site of the anterior superior iliac spine was stimulated to obtain CR electrophysiologically, and latency and duration were recorded with a needle electrode placed in the cremasteric muscle. Electrophysiologic evaluations were performed 24 h after injection of 0.1 ml of 10(6) cfu/ml Escherichia coli (0: 6 strain) in 1 ml of physiologic saline into the right testicle in OG, and 1 ml of saline only in SG. All testicles were sampled to check for orchitis after the electrophysiologic evaluations. Results: CR was obtained in all rats in CG and in 83.3% and 66.6% in SG and OG respectively (p 0.05). Histopathologic confirmation of orchitis was obtained in all testicle samples in OG, and number of neutrophils and total orchitis score was significantly higher in OG than the other groups (p < 0.05). Conclusion: Electrophysiologic parameters of CR may be altered in orchitis. Prolonged latency of CR in orchitis may be due to inflammation of the genitofemoral nerve or cremasteric muscle.
