Bashir Abdrhman Bashir, Mohamed Salih Ali
Background: Diabetes mellitus is a very rampant metabolic disorder, particularly type II. It has many complications such as the septic foot. Diabetic septic foot (DSF) patients are at high risk for coagulation abnormalities as well as surgical hazards. Owing to the potential sequelae of coagulation and vascular abnormalities, this work aimed at studying the hemostatic state and platelet indices in diabetes type II patients with septic foot. Methods: A case-control study was conducted during the period from July to September 2017 at Dr...

One homogeneous polysaccharide (ZWP) was successfully isolated and purified from the rhizomes of Curcuma zedoaria and the aim of present study was to determine the potential of chitosan/silk hydrogel sponge loaded with platelet-rich plasma exosomes (PRP-Exos), ZWP or PRP-Exos/ZWP on wound-healing in diabetic rats. An in vivo diabetic wound healing study showed that separate or combined treatments all resulted in a wound contraction in diabetic rats, as evidenced by a decrease of ulcer and an increase of epidermal thickness, but PRP-Exos/ZWP combination therapy was more successful in wound closing than either PRP-Exos or ZWP single administration...

Immune thrombocytopenia (ITP) is an autoimmune disease defined by low platelet counts which presents with an increased bleeding risk. Several genetic risk factors (e.g., polymorphisms in immunity-related genes) predispose to ITP. Autoantibodies and cytotoxic CD8+ T cells (Tc) mediate the anti-platelet response leading to thrombocytopenia. Both effector arms enhance platelet clearance through phagocytosis by splenic macrophages or dendritic cells and by induction of apoptosis. Meanwhile, platelet production is inhibited by CD8+ Tc targeting megakaryocytes in the bone marrow...

Stroke and myocardial infarction are among the most common causes of mortality and disability in the world. The ischemic injury underlying these illnesses is complex, involving intricate interplays among many biological functions including energy metabolism, vascular regulation, hemodynamics, oxidative stress, inflammation, platelet activation, and tissue repair that take place in a context- and time-dependent manner. The current drug therapy of choice is to timely resupply the blood to the ischemic tissue; but reperfusion may introduce additional harm to the tissue through a process known as ischemia/reperfusion injury...

Background: A traumatic ulcer caused by diabetes mellitus (DM) is a lesion caused by an increase in advanced glycosylation end products (AGEs), which takes a long time to heal. AGEs cause angiogenesis, vasculogenesis and a decrease in leukocytes. Fibroblast proliferation and the number of glycosaminoglycans decline, thereby inhibiting the formation of granulation tissue, collagen deposition and platelet derivatives growth factor. The application of topical propolis extract gel to ulcers has an anti-inflammatory function, triggers angiogenesis and accelerates wound healing...

In type 2 diabetes (T2D), hepatic insulin resistance is strongly associated with non-alcoholic fatty liver disease (NAFLD). In this study, we hypothesized that DNA methylome of livers from patients with T2D, when compared to livers of individuals with normal plasma glucose levels, can unveil some mechanism of hepatic insulin resistance that could link to NAFLD. Using DNA methylome and transcriptome analyses of livers from obese individuals, we found that both hypomethylation at a CpG site in PDGFA (encoding platelet derived growth factor alpha) and PDGFA overexpression are associated with increased T2D risk, hyperinsulinemia, increased insulin resistance and increased steatohepatitis risk...

Pregnancy-related acute kidney injury (Pr-AKI) remains a large public health problem, with decreasing incidences in developing countries but seemingly increasing incidences in the United States and Canada. These epidemiologic changes are reflective of the advances in medical and obstetric care, as well as changes in underlying maternal risk factors. The risk factors associated with advanced maternal age, such as hypertension, diabetes, chronic kidney disease, and those associated with reproductive technologies such as multiple gestations, are increasing...

Pericyte desorption from retinal blood vessels and subsequent vascular abnormalities are the pathogenesis of diabetic retinopathy (DR). Although the involvement of abnormal signals including platelet-derived growth factor receptor-β (PDGFRβ) and vascular endothelial growth factor-A (VEGF-A) have been hypothesized in DR, the mechanisms that underlie this processes are largely unknown. Here, novel retinopathy mouse model (N-PRβ-KO) was developed with conditional Pdgfrb gene deletion by Nestin promoter-driven Cre recombinase (Nestin-Cre) consistently reproduced through early non-proliferative to late proliferative DR pathologies...

Platelets play a critical role in both the initiation and progression of atherosclerosis, and even more so in the ensuing atherothrombotic complications. Low-dose aspirin remains the mainstay of antiplatelet therapy in high-risk patients by reducing the risk of myocardial ischemia (MI), stroke, or death due to cardiovascular disease (CVD). However, antiplatelet therapies lose their efficacy in people with diabetes mellitus (DM), increasing the risk of future atherothrombotic events. The molecular mechanisms that promote platelet hyperactivity remain unclear but could be due to glycation-induced conformational changes of platelet membranes resulting in impaired aspirin entry, or less-efficient acetylation/compensatory increase in COX-2 expression in newborn platelets...

We describe the case of a Type I diabetic patient with a refractory foot ulcer that remained unhealed for 2 years despite conventional therapy. Autologous adipose-derived stromal vascular fraction suspended in autologous platelet-rich plasma was applied to the wound, which completely healed within 1 month. The wound remained closed with no complications for a 2-year follow-up. Reporting of this and similar cases may lead to larger clinical trials that will prove the efficacy of this therapy that may offer accelerated healing and lessen the financial burden of more expensive therapeutic modalities...

Mean platelet volume (MPV) was recently published as a possible marker of coronary artery disease in patients at high risk for major adverse cardiac events. Because platelets play an important role in atherosclerosis, we examined the relationship between critical limb ischemia (CLI) and MPV in patients with peripheral arterial occlusive disease (PAOD). Our study comprised 2124 PAOD patients. Univariate logistic regression was performed to analyze potential predictors for CLI. Nagelkerke's R² is reported. Cross validation was performed using the leave-one-out principle...

Preeclampsia is a major cause of adverse maternal and perinatal outcomes, but how to identify women and fetuses at increased risk for later adverse events is a challenge. This study aimed to investigate the risk factors for adverse maternal and perinatal outcomes in women with preeclampsia. Data from 1396 women with preeclampsia were retrospectively collected and analyzed. Eighteen candidate risk factors and 12 adverse outcomes were investigated. The following factors were found to be significantly associated with at least one adverse outcome: maternal age 35 years or older, multiple birth, the usage of assisted reproductive technology, living in a rural area, history of pregnancy-induced hypertension, male fetus, multigravida, or having polycystic ovary syndrome, hemolysis, elevated liver enzymes, and low platelet count syndrome, intrahepatic cholestasis of pregnancy, cardiovascular disease, gestational diabetes mellitus, systemic lupus erythematosus, thyroid disease, or liver disease...
