2024-06-29T14:49:45+00:00

Objective: The current study aimed to compare the renal effects of Empagliflozin with Linagliptin combined with Metformin in patients with type 2 diabetes mellitus (T2DM) and chronic kidney disease. combined with Metformin in patients with type 2 diabetes mellitus (T2DM) and chronic kidney disease.

Materials and Methods: We conducted a randomized clinical trial on diabetic patients aged over 18 years with chronic renal failure and an EGFR between 20 to 60 ml/minutes/1.73 m2 corrected with the MDRD equation. Between January and December 2023, a total of 150 cases in Imam Hossein Hospital were randomized into two study arms of 75 cases receiving Empagliflozin (10 mg/day) and metformin or Linagliptin (5mg/day) and metformin for 6 months. The primary outcome was a change in chronic kidney disease (CKD) stage, while serum creatinine, fasting blood sugar (FBS), proteinuria, and blood pressure were evaluated at baseline, 3 and 6 months later.

Results: The mean age of participants was 62.20 (± 4.45) years and 50% of them were females. Study indices including serum creatinine (P: 0.001), estimated glomerular filtration rate (eGFR) (P: 0.001), FBS (P: 0.001), HgA1c (P: 0.001), proteinuria (P: 0.001), and blood pressure (P: 0.001) reduced significantly over time in both groups. After adjustment for potential confounders, Empagliflozin reduced the level of serum creatinine independent of other factors.

Conclusion: Empagliflozin significantly reduces the level of serum creatinine compared to Linagliptin in patients with T2DM and chronic renal failure.

Predictors of Mortality among Intensive Care Unit (ICU) Hospitalized Diabetic Patients with COVID-19

2024-06-29T14:50:43+00:00

Objective: Diabetic patients with COVID-19 are at the higher risk of clinical complications and intensive care unit (ICU) admission. There is limited information available on the risk factors of mortality in diabetic patients with COVID-19 admitted to the ICUs. The aim of this study was identifying the mortality risk factors in diabetic patients with COVID-19 who are admitted to the ICU.

Materials and Methods: In this study, we conducted a descriptive-analytical observational analysis on 391 patients admitted to the ICU for 18 months. We assessed the demographic, clinical, pharmaceutical, laboratory and imaging data of diabetic patients and statistically analyzed them to identify mortality risk factors.

Results: The study found 156 (39.89%) diabetic out of 391 patients. The group of diabetic patients had significantly higher rates of endotracheal intubation (P< 0.001), mortality (P< 0.001), and complications during hospitalization due to COVID-19, including secondary bacterial infections (P = 0.005), venous thrombosis (P = 0.008), and gastrointestinal bleeding (P = 0.011), compared to the nondiabetic patient.

Conclusion: Patients with diabetes who also have COVID-19 tend to experience more severe clinical outcomes and a higher mortality rate when admitted to the intensive care unit. The likelihood of mortality in these patients is closely associated with factors such as stroke occurrence, oxygenation levels, and the presence of secondary infections at the time of admission.

Objective: Exercise and physical activity as an essential factor and an integral part in the prevention of standard management of diabetes, however, most people with diabetes are not active enough. The objective of this research was to identify the obstacles hindering the participation of diabetic patients in sports activities in Khuzestan province.

Materials and Methods: The study followed an exploratory-applicative approach, utilizing a mixed qualitative-quantitative methodology. The qualitative section involved 18 knowledgeable experts, while the quantitative section included all diabetes patients in Khuzestan province. The sample size for the quantitative section was determined to be 384 patients, based on Morgan's table. Data collection in the qualitative part was conducted through semi-structured interviews, resulting in the extraction of 46 concepts, 19 sub-categories, and 8 main categories over three stages. In the quantitative part, a researcher-designed questionnaire was used, based on the interview findings. The reliability of the questionnaire was assessed using Cronbach's alpha coefficient, which yielded a value of 0.90. Data analysis was performed using SPSS and Smart PLS software.

Results: The findings indicated that various factors act as barriers to the participation of diabetic patients in sports activities, including self-actualization (7.79), environmental (6.10), educational and research (5.83), managerial (5.72), cultural (2.85), physical and supportive (2.8), time (2.62), and economic (2.15) factors.

Conclusion: Therefore, it is recommended that sports and health officials in the province take measures to alleviate these obstacles and improve the quality of life for diabetic patients.

2024-06-29T14:52:00+00:00

Objective: The purpose of this experimental research is to investigate the effects of High-Intensity Interval Training (HIIT) and Lipoic Acid (ALA) supplementation on VEGFR-3 of pancreatic in diabetic Wistar rats model.

Materials and Methods: 20 male Wistar rats weighing 159 ± 3 gr and aged3 weeks, were randomly assigned into 4 groups:1) diabetes/sham, 2)diabetes/ ALA, 3)diabetes/exercise/sham, and 4) diabetes /exercise/ ALA. Diabetes was induced with streptozotocin (65 mg/kg dose) and Nicotinamide (120 mg/kg dose). After two weeks of familiarization with interval training, the rats started their main training, included 10 repetitions of 4 minutes of running on the treadmill with an intensity of 85-90% VO2max and 2 minutes of active rest between repetitions (5-10 m/min) for 5 sessions per week for 6 weeks. ALA supplement was taken at a dose of 20 mg/kg/day for 6 weeks. One-way ANOVA test used and Tukey's post hoc test at for analysis (P≤ 0.05).

Results: HIIT has a significant effect on blood glucose (P= 0.004) and insulin (P= 0.001) and VEGFR3 (P= 0.001) of pancreatic tissue of diabetic rats.

Conclusion: Lymphatic vessels play an important role in the pancreas and treat diabetes.The results of this research showed that HIIT and ALA increased lymphangiogenesis in the diabetic rat model.

Antibody Engineering to Enhancement of Ranibizumab Binding Affinity for the Prevention and Treatment of Diabetic Retinopathy

2024-06-29T14:52:44+00:00

Objective: The VEGF function blockage effectively reduces the progression of diabetic retinopathy. Ranibizumab and bevacizumab are some anti-VEGF monoclonal antibodies (mAb). Considering the importance of affinity maturation of ranibizumab, we aimed to find the essential amino acids of the ranibizumab antibody (Ab).

Materials and Methods: We tried to find the important amino acids of this antibody via Paratome, Meta-PPISP, and the WESA web server. Subsequently, these amino acids were mutated to improve the binding affinity of the Ab variants to antigen (Ag). In this regard, the ranibizumab anti-VEGF-A was mutated. The structural docking prediction of the ranibizumab-VEGF-A complex was used for the design and validation of ranibizumab with a higher affinity for binding to VEGF-A. Finally, we measured the binding affinity of Ab variants to Ag by computational docking.

Results: Bioinformatic analyzes such as molecular docking and dynamics showed that several mutant variants successfully improved the properties of Ab binding compared to the wild-type Ab.

Conclusion: Consistent with the use of anti-VEGF monoclonal antibodies in the treatment of diabetic retinopathy, the mutant variants of ranibizumab may be potential candidates for stronger affinity binding to VEGF, which may affect the specificity and sensitivity of the antibody.

Vildagliptin-Associated Bullous Pemphigoid: A Case Report

2024-06-29T14:53:39+00:00

Objective: Bullous pemphigoid is a rare autoimmune skin disorder characterized by blistering, urticarial lesions, which are sometimes associated with adverse drug reactions. Vildagliptin is an oral anti-diabetic agent that selectively inhibits the dipeptidyl peptidase-4 (DPP-4) enzyme

Materials and Methods: A 75-year-old female with a known case of type 2 Diabetes Mellitus, hypertension, and hypothyroidism for the last 10 years presented with pruriginous tense bullous skin lesions over her both palms and soles. There was no mucosal involvement. Further interrogation revealed that she started taking Vildagliptin 5 days ago which was prescribed due to high levels of post-prandial blood sugar level despite already intake of Glimepiride-4 mg and Metformin-3 gm.

Results: Vildagliptin was immediately advised to be stopped. She was treated with antihistamines, steroids, and conservative management which led to remission of the blisters

Conclusion: Vildagliptin is the probable causative drug for developing bullous pemphigoid skin lesion which shows temporal association in this case as other concomitant drugs has no direct correlation. Therefore physicians must be aware of this rare life-threatening side effect of this medicine and advice patients to visit the hospital even the slightest cutaneous manifestation. Bullous pemphigoid can result in fatal life-threatening conditions if not treated early.

Genetic and Epigenetic Etiologies of Type 1 Diabetes Mellitus

2024-06-29T14:54:19+00:00

Numerous suspect genes associated with type 1 diabetes mellitus (T1DM) have been identified, suggesting a need to focus on the disease's causal genes and mechanisms. This necessitates an update to raise public awareness. This review articulates genes with mutations that predispose individuals to T1DM. We conducted a comprehensive search of academic databases, including Web of Science, Scopus, PubMed, and Google Scholar, for relevant materials. Available information indicates that at least 70 genes are suspected in the pathogenesis of T1DM. However, the most frequently implicated genes include human leukocyte antigen (HLA), insulin (INS), cytotoxic T lymphocyte-associated antigen 4 (CTLA-4), and protein tyrosine phosphatase non-receptor type 22 (PTPN22). Mutations or variants in these genes may lead to insulin insufficiency and, consequently, T1DM by tricking immune cells, such as T-cells and B-cells, into attacking self-antigens and triggering the autoimmunity of beta cells. Furthermore, this pathophysiology can be mediated through aberrant epigenetic modifications, including DNA methylation, histone post-translational modifications, and noncoding RNAs, in the mentioned genes. Some of these pathophysiologies are gene-specific and may have an epigenetic origin that is reversible. In the event of an epigenetic origin, a treatment for T1DM that addresses the causal genes or reverses epigenetic changes and their mechanisms could yield improved outcomes. Medical professionals are encouraged to design therapeutic regimens that specifically target the mentioned genes and address the identified epigenetic alterations in individuals expressing such etiologies.
