Abstract Background Chronic kidney disease (CKD) represents a global health concern. The Global Burden of Disease study stated that, worldwide mortality attributed to renal failure showed a tremendous rise with around 1.2 million deaths from renal failure in 2015. Hemodialysis (HD) patients are at increased risk for atherosclerotic disorders including peripheral arterial disease (PAD). Among dialysis patients, many of the risk factors for PAD are the same as for the general population, but there are associations that seem to be unique to dialysis patients. Objective To study the relation between PAD assessed by ankle brachial index (ABI) and serum level of 25(OH) vitamin D among Maintenance HD Patients. Patients and Methods The present study included 90 subjects, 45 end stage renal disease patients patients(ESRD) on maintenance HD with PAD assessed by ABI (value less than 0.9) and 45 ESRD patients on maintenance HD without PAD assessed by ABI (value more than or equal 0.9). Results There was a statistically significant difference between the two studied groups as regard serum 25(OH) vitamin D level (P = 0.000). We also found a statistically significant positive correlation between ABI and serum vitamin D level in both patients and control groups (P = 0.000). Conclusion Vitamin D deficiency is associated with PAD among maintenance HD patients.

Abstract. Background: Osteoprotegerin plays a role in the development of several bone diseases. In addition, osteoprotegerin may contribute to the development of vascular disease. Little is known about the association between serum osteoprotegerin levels and the presence or severity of peripheral arterial disease (PAD). The aim of this study was to examine the association between serum osteoprotegerin levels and both the presence as well as the severity of lower extremity arterial disease in patients with type 2 diabetes (T2DM). Patients and methods: The study included 165 consecutive patients with T2DM (57 % males, mean age 65.0 ± 0.7 years). PAD was diagnosed by measurement of the toe-brachial index (TBI). Serum osteoprotegerin was measured using ELISA. Results: The mean osteoprotegerin level was significantly higher in patients with PAD in comparison to patients without PAD (18.2 ± 1.0 vs. 13.1 ± 2.0 pmol/L, p = 0.014). Significant univariate correlations between TBI and osteoprotegerin level (r = –0.308; p < 0.001), age, body mass index, and HDL cholesterol were observed. In the multivariate linear regression analysis, serum osteoprotegerin (β = –0.005; p = 0.020), higher age, and male gender were significant predictors of TBI. When 25(OH) vitamin D was introduced into the mentioned model, OPG was no longer a significant predictor of TBI and was replaced in the model with vitamin D (β = 0.009, p = 0.001). This finding suggests a role of OPG as a mediator of the effects of 25(OH) vitamin D. Conclusions: Serum osteoprotegerin level is significantly associated with both the presence and severity of PAD in patients with T2D. Osteoprotegerin might be a biomarker for the presence of atherosclerotic disease in patients with T2DM.

Abstract Introduction Antiplatelet therapy is the cornerstone of treatment for many atherosclerotic vascular pathologies including peripheral arterial disease (PAD). Patients with PAD often have comorbid conditions that require complex antithrombotic therapy, i.e. combined antiplatelet and anticoagulation. Methods All adult patients undergoing ankle brachial index (ABI) measurements were included in the study. ABI values between 1.00 and 1.40 were considered normal, and values below 1.00 or above 1.40 were considered PAD. Demographic, comorbidity and outcome data were obtained using diagnostic codes from the electronic health record. Three medication classes were analyzed: aspirin, non-aspirin oral antiplatelets (e.g. P2Y12 inhibitors) and oral anticoagulants (warfarin and the direct oral anticoagulants). Medication use was determined for patients who had been on a medication for at least one year. Cox proportional hazard analysis for the time to first bleeding event was analyzed. Bleeding was defined as any bleeding requiring medical evaluation (including clinically-relevant non-major bleeding and major bleeding). Results In all, 40,144 patients were included in the analysis (mean age 66±15, 43% female). Patients with PAD were more likely to be on double therapy (one antiplatelet with anticoagulation) (28% vs 19%) and triple therapy (dual antiplatelet with anticoagulation) (10% vs 4%). Unadjusted hazard ratios for bleeding risk showed increased risk of bleeding for patients with PAD (1.18, 95% confidence interval [CI]: 1.08–1.29), though the association is no longer present after adjustment for antithrombotic therapy. Adjusting for age, sex and PAD class, compared to no antithrombotic therapy, there was increased risk of bleeding for monotherapy (1.91, 95% CI: 1.61–2.26), double therapy (3.40, 95% CI: 2.89–4.00) and triple therapy (5.00, 95% CI: 4.21–5.96). Among medications, aspirin and anticoagulant use was independently associated with the greatest increase in risk of bleeding. Conclusion Patients in PAD are at increased risk of bleeding secondary to antithrombotic therapy. Complex antithrombotic therapy with double or triple therapy confer additional bleeding risk, particularly regimens containing aspirin and oral anticoagulants.

Abstract Background Elevated lipoprotein (a) [LP (a)] levels are an independent, genetic, and causal factor for cardiovascular disease and associated with myocardial infarction (MI). Although the association between circulating levels of lipoprotein(a) [Lp(a)] and risk of coronary artery disease (CAD) is well established, its role in risk of peripheral arterial disease (PAD) remains unclear. PAD affects over 236 million individuals and follows ischaemic heart disease (IHD) and cerebrovascular disease (CVD) as the third leading cause of atherosclerotic cardiovascular morbidity worldwide. LP (a) is genetically determined, stable throughout life and yet refractory to drug therapy. While 30 mg/dl is considered the upper normal value for LP (a) in central Europe, extremely high LP (a) levels (&gt;150mg/dl) are rare in the general population. The aim of our study was to analyse the correlation between lipoprotein (a) [LP (a)] levels and an incidence of PAD in high-risk patients. Patients and methods We reviewed the LP (a) concentrations of 52.898 consecutive patients admitted to our cardiovascular center between January 2004 and December 2014. Of these, 579 patients had LP (a) levels above 150 mg/dl (mean 181.45±33.1mg/dl). In the control collective LP (a) was &lt;30mg/dl (n=350). Other atherogenic risk factors in this group were HbA1c 6.58±1.65%, low density lipoprotein (LDL) 141.99±43.76 mg/dl, and body mass index 27.81±5.61. 54.40% were male, 26.07% were smokers, 93.2% had hypertension, and 24% had a family history of cardiovascular diseases. More than 82.6% were under statins. The mean glomerular filtration rate (GFR) was 69.13±24.8 ml/min [MDRD (Modification of Diet in Renal Disease)]. Results 45.00% (n=261) of the patients with LP (a) &gt;150mg/dl had PAD. The prevalence of PAD in patients with LP (a) &lt;30mg/dl in our control collective was 15.8%. (P- Value 0.001). Patients with LP (a) &gt;150mg/dl had a significantly increased risk for PAD (Odds ratio 4.36, 95% CI 2.94–6.72, p: 0.001). 19.1% of patients were re-vascularized by percutaneous angioplasty (PTA) and 7.09% of patients had to undergo peripheral vascular bypass (PVB). Mean LP (a) level in patients with PAD was 182.6±31.61. Conclusion Elevated LP (a) levels above 150 mg/dl are associated with a significantly increased risk of PAD in our collective and it confirms our hypothesis. Over one fourth of these patients had severe PAD and requiring revascularization therapy. We need more prospective studies to confirm our findings.

Introduction: Markers of endothelial function may be associated with increased risk for cardiovascular disease; however, prospective data for peripheral arterial disease (PAD) are limited. We evaluated the hypothesis that serum markers of endothelial dysfunction are associated with an increased risk of PAD among women. Methods: We conducted a nested case-control study within an ongoing prospective cohort of U.S. female nurses (Nurses’ Health Study). Among 32,826 NHS participants who provided blood samples in 1989-1990, after excluding those who had myocardial infarction, coronary heart disease, stroke, or carotid artery surgery prior to the PAD diagnosis, we included all incident PAD cases that occurred between 1990 and 2008 and were confirmed by medical records. Each case was individually matched with three eligible controls using risk-set sampling, by age, smoking, date of blood draw, and fasting status. We evaluated the association between serum levels of soluble intercellular adhesion molecule (ICAM-1), E-selectin, and the risk of PAD, using conditional logistic regression analysis. Results: Complete biomarker data from 1990 was available for 144 cases and 431 controls. After accounting for matching factors, baseline ICAM-1 levels were associated with higher risk of PAD (RR for highest (T3) vs. lowest (T1) tertile=1.75, 95% CI: 1.05-2.90). The association was attenuated and no longer significant (RR T3 vs. T1=1.37, 95% CI: 0.75-2.49) after adjusting for serum levels of HDL and LDL-cholesterol, family history of myocardial infarction, relative weight, reported aspirin and cholesterol-lowering medication use, hypertension and diabetes diagnoses, physical activity, and pack-years of smoking. Additional adjustment for CRP levels further attenuated the relative risk (RR T3 vs. T1= 1.24, 95% CI: 0.67-2.29). We did not observe any significant association between baseline E-selectin levels and the risk of PAD (multivariate- and CRP-adjusted RR T3 vs. T1=0.93, 95% CI: 0.54-1.59). Conclusions: There was no association between ICAM-1 and E-selectin and subsequent PAD in this cohort of U.S women.

Background: To investigate the relationship between pleural empyema (PE) and peripheral arterial disease (PAD).Methods: We conducted a retrospective cohort study using data from the National Health Institute Research Database. Univariable and multivariable Cox's proportional hazard regressions were performed to investigate the association between PE and the risk of PAD. Kaplan–Meier method and the differences were assessed using a log-rank test.Results: The overall incidence of PAD was higher in the PE cohort than in the non-PE cohort (2.76 vs. 1.72 per 1,000 person-years) with a crude hazard ratio (HR) of 1.61 [95% confidence interval (CI) = 1.41–1.83]. After adjustment for age, gender, and comorbidities, patients with PE were noted to be associated with an increased risk of PAD compared with those without PE [adjusted HR (aHR) = 1.18, 95% CI = 1.03–1.35]. Regarding the age-specific comparison between the PE and non-PE cohorts, PAD was noted to be significantly high in the ≤ 49 years age group (aHR = 5.34, 95% CI = 2.34–10.1). The incidence of PAD was higher in the first 2 years, with an aHR of 1.35 (95% CI = 1.09–1.68) for patients with PE compared with those without PE.Conclusion: The risk of PAD was higher if patients with PE were younger than 49 years and within the 2-year diagnosis of PE.

BackgroundPeripheral arterial disease and vascular calcifications contribute significantly to the outcome of dialysis patients. The aim of this study was to evaluate the prognostic role of severity of abdominal aortic calcifications and peripheral arterial disease on outcome of peritoneal dialysis (PD) patients using methods easily available in everyday clinical practice.MethodsWe enrolled 249 PD patients (mean age 61 years, 67% male) in this prospective, observational, multicenter study from 2009 to 2013. The abdominal aortic calcification score (AACS) was assessed using lateral lumbar X ray, and the ankle-brachial index (ABI) using a Doppler device.ResultsThe median AACS was 11 (range 0 – 24). In 58% of the patients, all 4 segments of the abdominal aorta showed deposits, while 19% of patients had no visible deposits (AACS 0). Ankle-brachial index was normal in 49%, low (< 0.9) in 17%, and high (> 1.3) in 34% of patients. Altogether 91 patients (37%) died during the median follow-up of 46 months. Only 2 patients (5%) with AACS 0 died compared with 50% of the patients with AACS ≥ 7 ( p < 0.001). The adjusted hazard ratio for all-cause mortality was 4.85 (95% confidence interval [CI] 1.94 – 24.46) for aortic calcification (AACS ≥ 7), 2.14 for diabetes (yes/no), 0.93 for albumin (per 1 g/L), and 1.04 for age (per year). A low or high ABI were not independently associated with mortality.ConclusionsSevere aortic calcification was a strong predictor of all-cause mortality in PD patients. The evaluation of aortic calcifications by lateral X ray is a simple method that allows the identification of high-risk patients.
