Diabetes that is uncontrolled for an extended period of time is linked to substantial comorbidities and organ damage. The purpose of the current study is to assess the effect of coadministration of omega-3 fatty acids with glimepiride on blood glucose, lipid profile, serum irisin, and sirtuin-1 levels in T2DM patients. Methods This clinical trial involved 70 type 2 diabetic patients randomly assigned to glimepiride 3 mg with either omega-3 capsules contained fish oil 1000 mg, 13% of eicosapentaenoic acid (EPA) and 9% docosahexaenoic acid (DHA) (omega-3 group, n = 35) or placebo capsules contained corn oil and linoleic acid (control group, n = 35) daily for three months. Blood samples were obtained at the start of the study and 12 weeks later for biochemical examination of HbA1c%, FBG, fasting insulin, and lipid profil...

This study aims to compare the effects of Dapagliflozin versus Glimepiride on glycemic control, insulin resistance, and biomarkers as (extracellular domain of insulin regulated aminopeptidase) IRAPe, (interleukin-34) IL-34, and (N-terminal pro b-type natriuretic peptide) NT-proBNP. This study included 60 type 2 diabetic patients, who are randomized to receive either Glimepiride 4 mg/day (group 1) or Dapagliflozin 10 mg/day (group 2). Blood samples were collected at baseline and after 3 months of treatment for biochemical analysis. Additionally, HOMA-IR is calculated. After 3 months of receiving the intervention, there is no significant difference between the effects of Glimepiride and Dapagliflozin on FBG, PPBG, HbA1C%, fasting insulin, and HOMA-IR. The difference between both groups is significant for IL-34 (p = 0.002) and non-significant fo...

The aim of this study was to investigate the protective role ofl-carnitine in rats against TRZ-induced cardiotoxicity, as well as to look into the molecular mechanisms underlying its cardioprotective effects via autophagy-mediated cell death and oxidative stress. Male albino rats were randomized into four experimental groups (n = 8): normal control, TRZ group (TRZ, 20 mg/kg/day),l-carnitine group (LC, 200 mg/kg/day), and Co-treated group (l-carnitine and TRZ). All treatments were administered via oral gavage for 4 weeks. Cardiac enzymes (AST & CK-MB) and serum cardiac troponin T(cTnI) were assessed. Oxidative stress biomarkers in heart tissue (malondialdehyde; MDA, total thiol, and catalase activity) were measured. Autophagy related-genes (ATG-5 and Beclin-1), P62, and TNF-α were quantified. AST and CK-MB and cTnI significantly (...

Candesartan is an angiotensin II-receptor blocker and has proved neuroprotective properties. This study aimed to investigate the neuroprotective effect of candesartan against d-galactose induced neuroinflammation and memory deficit via autophagy. METHODS Twenty-eight male Wistar rats aged 3 months were divided into four equal groups: control (vehicle), d-gal (100 mg/kg d-galactose), cand (1 mg/kg candesartan), and cand+d-gal (100 mg/kg d-galactose & 1 mg/kg candesartan). All treatments were given orally and daily for 4 weeks. Assessment of memory was done using Morris water maze (MWM) test. Brain tissue was assessed for malondialdehyde (MDA), total thiol, catalase activity, and gene expression of TNF-α, GDNF-1 as well as autophagy genes (Beclin 1 and ATG 5). RESULTS Prophylactic treatment of candesartan in d-galactose-treated rats significantly (p < 0.001) reduced oxidative stress via reduction of MDA as well as elevation of catalase activity and total thiol levels. Additionally, candesartan prophylactic treatment significantly increased gene expression of GDNF-1 and decreased gene expression of TNF-α. Furthermore, candesartan significantly increased the expression of autophagy related gene (Beclin 1 and ATG 5) in cand+d-gal treated rats. These results were supported by the histopathological findings which showed that candesartan prevented the neuronal injury in the cerebral cortex and hippocampus of the d-galactose-treated rats. Moreover, MWZ test showed that candesartan significantly improved memory deficit in cand+d-gal treated rats. CONCLUSION Candesartan prevents d-galactose-induced neurotoxicity and memory deficit via activating autophagy and decreasing oxidative stress. Therefore, candesartan was a good candidate for age-related neurodegenerative disorders and memory deficit.

PURPOSE To examine the efficacy of both rosuvastatin (ROSUVA) and atorvastatin (ATORVA) on LV function and markers of inflammation in T2D patients with dyslipidemia. METHODS One hundred-sixty T2D patients were assigned to receive either atorvastatin (ATORVA group, n = 80, 40 mg) or rosuvastatin (ROSUVA group, n = 80, 10 mg), daily for 6 months. Blood was collected for biochemical analysis. The prevalence of left ventricular abnormalities was determined by echocardiography and two-dimensional Speckle-Strain to assess Global Longitudinal Strain (GLS). RESULTS ROSUVA vs. ATORVA resulted in significant (p < 0.001) reduction in HbA1c % (9.13 vs 2.35%), LDL-C (22.23% vs. 14.75%), triglycerides (13.56 % vs. 8.21 %), total cholesterol (16.10 % vs. 10.81 %), atherogenic index (18.08. % vs. 10.97%), hs-CRP (23.51 % vs.18.96%), sortilin (33.33 % % vs. 15.08 %), and leptin (31.81 % vs. 23.17 %) but increased adiponectin (97.99 % vs.76.47.1 %) and HDL-C (76.47 % vs. 0.21 %) compared with baseline, respectively. Negative correlations between adiponectin and each of hs-CRP, HbA1c%, total cholesterol, LDL-C, atherogenic index and leptin were found. Also, left ventricular functions were correlated with adiponectin, lipids, HbA1c% and hs-CRP. The areas under receiver operating characteristic curve (AUC) showed that hs-CRP, leptin, sortlin, leptin, and adiponectin were good predictors for cardiovascular events. CONCLUSION ROSUVA is more efficacious in improving lipid profile, atherogenic index and modulation of inflammatory biomarkers in dyslipidemic T2D patients compared with ATROVA. However, both statins are equivalent as cardioprotective agents in dyslipidemic T2D patients.

METHODS This observational parallel-group study was conducted in 60 subjects without T2DM who served as a control group and 60 patients with newly diagnosed T2DM. The 2 groups were matched for age, sex ratio, and body mass index. Anthropometric parameters; fasting blood glucose; fasting plasma insulin; Homeostatic Model Assessment for IR (HOMA-IR) index; glycated hemoglobin (HbA1c); and circulating levels of IL-34, visfatin, irisin, and IRAPe were assessed. RESULTS The group with T2DM showed significantly higher IL-34 and visfatin levels and significantly lower irisin and IRAPe levels as compared to the healthy control group. IL-34 and visfatin were significantly positively correlated with fasting blood glucose, fasting plasma insulin, HOMA-IR, and HbA1c. On the other hand, irisin and IRAPe were significantly negatively correlated with fasting blood glucose, fasting plasma insulin, HOMA-IR, and HbA1c. IL-34 was positively associated with visfatin, while negatively associated with both irisin and IRAPe. IMPLICATIONS IL-34, visfatin, irisin, and IRAPe may play a vital role in T2DM and in diabetes-associated IR. Additionally, IRAPe may represent a useful and direct marker for use in the detection of IR in the diabetic population. ClinicalTrials.gov identifier: NCT04107259.

This study was designed to investigate the potential protective effects of l-carnitine against trazadone-induced testicular toxicity in male rats and the possible underlying mechanisms such as oxidative stress, inflammation and autophagy. METHODS thirty-two male Wistar rats were divided randomly into four groups (n = 8). Testicular damage was induced by oral administration of Trazadone (TRZ, 20 mg/kg/day, p.o.) for four weeks (TRZ group). l-carnitine (LC, 200 mg/kg/day, p.o.) was applied for four weeks (LC group). LC + TRZ group administered the same doses of LC and TRZ concomitantly. The control group received distilled water (as vehicle). RESULTS the protective treatment with LC attenuated the decline of sperm count and motility resulted from trazadone administration. Moreover, LC ameliorated trazadone increased lipid peroxidation (MDA) and reduction of total thiol and catalase activity. LC modulated the elevation in tumor necrosis factor- α (TNF-α), and increased the expression of autophagy related genes Becline-1, ATG 5, ATG-12 in rat testes. Serum level of FSH, LH and total testosterone were increased significantly (p < 0.001) in LC + TRZ group. Histopathological findings further supported the protective effects of LC against trazadone -induced testicular injury by increasing free sperms within the lumen of spermatogenic cells and improving testicular degeneration. CONCLUSION These findings supported the protective effects of l-carnitine on rat testes due to suppression of oxidative stress, inflammation and enhancing autophagy. l-carnitine may be recommended as adjuvant therapy to trazadone treatment.
