Diabetic neuropathic osteoarthropathy (DNOAP) is an uncommon, but with considerable morbidity and mortality rates, complication of diabetes. The real pathogenesis is still unclear. The two popular theories are the neuro-vascular theory and neuro-traumatic theory. Most theories and pathways focused on the uncontrolled inflammations that resulted in the final common pathway, receptor activator of nuclear factor κβ ligand (RANKL)/osteoprotegerin (OPG) axis, for the decreased bone density in DNOAP with an osteoclast and osteoblast imbalance...

BACKGROUND: High mobility group box-1 (HMGB-1) is a nuclear protein also acting as inflammatory mediator, whilst osteoprotegerin (OPG), member of tumor necrosis factor receptor superfamily, is indicated as marker of vascular calcification. Peripheral artery disease (PAD) and type 2 diabetes (T2D) are clinical conditions characterized by elevated serum inflammatory markers and vascular calcification enhancement. The aim of this study was to investigate the potential role of HMGB-1, OPG and several inflammatory mediators such as C-reactive protein (HsCRP), tumor necrosis factor-alpha and interleukin-6 (IL-6) on the presence and severity of peripheral artery disease in patients with T2D...

BACKGROUND: Osteoprotegerin (OPG) and von Willebrand factor (VWF) form complex within endothelial cells and following secretion. The nature of blood group antigens strongly influences the levels of circulating VWF, but there is no available data concerning its ascendancy on OPG levels. We aimed to assess the relationship of AB0 blood groups with OPG, VWF levels (VWF: Ag) and collagen binding activity (VWF: CB) in peripheral arterial disease (PAD) patients. METHODS: Functional and laboratory parameters of 105 PAD patients and 109 controls were examined...

OBJECTIVES: We examined the association of TNF-related apoptosis-inducing ligand (TRAIL) concentrations with cardiovascular disease (CVD) in rheumatoid arthritis (RA) and, since osteoprotegerin (OPG) can act as a decoy receptor for TRAIL, whether TRAIL concentrations impact on the OPG level-atherosclerotic CVD relation that was recently documented in the present cohort. METHODS: TRAIL concentrations were assessed by ELISA in 151 RA patients of which 75 (49.7%) had CVD comprising ischaemic heart disease (n=27), cerebrovascular accident (n=26), peripheral artery disease (n=9) or/and heart failure (HF) (n=27), and 62 controls...

OBJECTIVE: We determined whether osteoprotegerin (OPG) concentrations are associated with established cardiovascular disease (CVD) among patients with rheumatoid arthritis (RA). METHODS: OPG concentrations were measured by ELISA in 151 patients with RA (54 with CVD) and 62 age-matched control subjects without CVD. Established CVD was composed of documented ischemic heart disease, cerebrovascular disease, and peripheral artery disease. RESULTS: In patients with RA, age, body mass index (BMI), rheumatoid factor (RF) positivity, anticyclic citrullinated peptide (anti-CCP) antibody positivity, and joint erosion status were associated with OPG concentrations [partial R (p) = 0...

AIMS: Osteoprotegerin (OPG) is a secretory glycoprotein that belongs to the tumor necrosis factor receptor family and plays a role in atherosclerosis. OPG has been hypothesized to modulate vascular functions; however, its role in mediating atherosclerosis is controversial. Epidemiological data in patients with cardiovascular disease (CVD) indicate that OPG serum levels are associated with several inflammatory markers, myocardial infarction events, and calcium scores, suggesting that OPG may be causative for CVD...

BACKGROUND: Objective performance goals (OPGs) are a set of standardized end points generated from well documented historical controls against which new therapeutic procedures may be compared in single-arm studies. Recently, the Society for Vascular Surgery suggested a set of OPGs designed from vein bypass controls that could be used to evaluate the safety and efficacy of endovascular devices applied to critical limb ischemia through a noninferiority analysis. Our aim is to analyze the results of infrapopliteal endovascular procedures performed in patients with critical limb ischemia according to these OPG end points...

Abdominal Aortic Aneurysm (AAA) is multifactorial disease with unknown ethiology. Among the theories on the pathogenesis of AAA are some ge. netic factors, infections, disorders in connective tissue (collagenosis), arteriosclerosis, inflammation, incorrect immune response (autoimmunity). It was discovered that crucial for AAA development is intense inflammatory reaction combined with high proteolytic activity. Recent evidence confirmed the association between osteopontin (OPN) and osteoprotegerin (OPG) levels and cardiovascular diseases and arterio...

INTRODUCTION: Peripheral arterial disease (PAD) and type 2 diabetes mellitus (DM) are both associated with excessive vascular calcification and elevated levels of inflammatory markers IL-6 and hsCRP. The recently identified Osteoprotegerin(OPG)/RANKL/TRAIL pathway has been implicated in vascular calcification, but data on levels in PAD and effect of co-existent DM are lacking. MATERIALS AND METHODS: 4 groups of patients were recruited - 26 with PAD and DM, 35 with DM alone, 22 with PAD alone, and 21 healthy individuals...

Michael S Conte
Critical limb ischemia (CLI), the most advanced form of peripheral arterial disease, is associated with a high rate of limb loss and substantial mortality. Revascularization remains the cornerstone of limb salvage in the CLI patient, and surgical bypass is the established standard. Endovascular therapies, such as angioplasty, atherectomy, and stenting offer a less-invasive option, but evidence of efficacy is lacking, and no devices are currently approved specifically for CLI. Design and execution of clinical trials in the CLI population are challenging, in part because of the lack of consensus on cohort definitions and relevant endpoints...
