Abstract These case reports aim to show that hyperfibrinogenemia is a risk factor for the progression and prognosis of peripheral arterial disease (PAD), in patients with and without diabetes mellitus type 2. We present a patient with PAD who has type 2 diabetes mellitus, who has previously been repeatedly treated for lower limb ischemia with multiple vascular surgeries performed. A few weeks before admission the patient developed critical lower limb ischemia, which was treated with an iliaco-popliteal and femorofemoral bypass. The patient had elevated serum fibrinogen values. In the current admission, renewed left limb ischemia was diagnosed, and surgically evaluated with a recommendation for amputation of the left limb as a surgical recommendation. Our second patient had a stable intermittent claudication, dyslipidemia and hyperfibrinogenemia. He was successfully treated for those risk factors. Regular monitoring of the patient showed improved claudication distance and quality of life Our case reports, supported by a literature review, demonstrate that hyperfibrinogenemia is a possible risk factor for progression and the prognosis of PAD.

Abstract Background: Risk factors for peripheral arterial disease are generally the same as those responsible for the ischemic heart disease and in both cases are overlapping risk factors involved in the etiology of atherosclerosis, such as smoking, dyslipidemia, diabetes and hypertension. Case report: We present a case of a 61 years old male, whose ischemic peripheral symptoms began in 2003, at the age of 49, presenting as a Leriche syndrome. The patient was subjected to first revascularization procedure consisting in aortic-bifemoral grafting in the same year. General examination revealed no risk factors except smoking. Only a year after, he returns with critical right lower limb ischemia due to bypass thrombosis, therefore two thrombectomies were performed followed by a right side femoro-popliteal bypassing with Dacron prosthesis. The patient’s condition was good until 2008 when a femoro-popliteal bypass using inverted autologus saphenous vein was imposed due to occlusion of the previous graft. In 2013 the patient was readmitted to hospital with left lower limb critical ischemia. A femoro-popliteal bypass was performed, followed by two thrombectomies and the amputation of the left thigh. Up to this date, the patient kept smoking. Discussions: Although our patient has a low/medium risk level of atherosclerosis by Framingham score and a minimum Prevent III score, all the surgical revascularization procedures were not able to avoid the amputation. Conclusions: There are enough reasons to believe that smoking as a single risk factor can strongly influence the unfavorable progression to amputation in patients with peripheral arterial disease.

Abstract Background: Chronic lower limb ischemia develops earlier and more frequently in patients with type 2 diabetes mellitus. Diabetes remains the main cause of lower-extremity non-traumatic amputations. Current medical treatment, based on antiplatelet therapy and statins, has demonstrated deficient improvement of the disease. In recent years, research has shown that it is possible to improve tissue perfusion through therapeutic angiogenesis. Both in animal models and humans, it has been shown that cell therapy can induce therapeutic angiogenesis, making mesenchymal stromal cell-based therapy one of the most promising therapeutic alternatives. The aim of this study is to evaluate the feasibility, safety and efficacy of cell therapy based on mesenchymal stromal cells derived from adipose tissue intramuscular administration to patients with type 2 diabetes mellitus with critical limb ischemia and without possibility of revascularization. Methods: A multicenter, randomized double-blind, placebo-controlled trial has been designed. 90 eligible patients will be randomly assigned at a ratio 1:1:1 to one of the following: the control group (n=30), low cell dose treatment group (n=30), and high cell dose treatment group (n=30). Treatment will be administered in a single-dose way and patients will be followed for 12 months. Primary outcome (safety) will be evaluated by measuring the rate of adverse events within the study period. Secondary outcomes (efficacy) will be measured by assessing clinical, analytical and imaging-test parameters. Tertiary outcome (quality of life) will be evaluated with SF-12 and VascuQol-6 scales. Discussion: Chronic lower limb ischemia has limited therapeutic options and constitutes a public health problem in both developed and underdeveloped countries. Given that the current treatment is not established in daily clinical practice, it is essential to provide evidence-based data that allow taking a step forward in its clinical development. Also, the multidisciplinary coordination exercise needed to develop this clinical trial protocol will undoubtfully be useful to conduct academic clinical trials in the field of cell therapy in the near future.Trial registration: ClinicalTrials.gov NCT04466007.

Aim: Diabetes mellitus increases the risk of peripheral artery disease (PAD) 2 times. PAD is diagnosed by ABI (Ankle Brachial Index). PAD increases mortality and morbidity of patient with Diabetes Mellitus (DM) Type 2. This study aims to determine the prevalence and risk factors of PAD in the population of type 2 diabetes mellitus (DM) in Yogyakarta, Indonesia.   Methods: This study was a community-based descriptive and analytic observational study that examines the prevalence and risk factors of PAD in type 2 diabetes mellitus. Diagnosis of PAD was detected by ABI examination using VaSera VS-1500N. All patients with type 2 diabetes mellitus in Yogyakarta who meet the inclusion criteria will be enrolled in this study. The research subjects were taken in multi-stage, cluster-random sampling in Yogyakarta. The patient will undergo an interview of demographic data which were assessed by one assessor.  Data from interviews and ABI examinations were analysed statistically.   Results: Two hundred and fifty-six (256) patients with type 2 DM consisted of 188 patients (73.4%) women and 68 patients (26.6%) men. Prevalence of PAD diagnosed by abnormal ABI was found in 41 (16%) of 256 patients. Subjects with age more than 67 years old was significantly associated with PAD occurrence (P=0,001) in type 2 DM population.   Conclusion: The prevalence of PAD was 16% of 256 type 2 DM patients. Age more than 67 years old was the strong risk factor of PAD in type 2 DM.   Key words: Ankle Brachial Index, Peripheral Arterial Disease, Diabetes mellitus, Prevalence, Risk Factor

Background: Vascular inflammation plays a crucial role in peripheral arterial disease (PAD), although the role of the mediators involved has not yet been properly defined. The aim of this work is to investigate gene expression and plasma biomarkers in chronic limb-threating ischemia (CLTI). Methods: Using patients from the GHAS trial, both blood and ischemic muscle samples were obtained to analyze plasma markers and mRNA expression, respectively. Statistical analy-sis was performed by using univariate (Spearman, t-Student, X2) and multivariate (multiple lo-gistic regression) tests. Results: 35 patients were available at baseline (29 for mRNA expression). Baseline characteristics (mean): Age:71.4±12.4 (79.4% male); TNF-α:10.7±4.9; hs-CRP:1.6±2.2; Neutrophil-to-lymphocyte ratio (NLR):3.5±2.8. Plasma TNF-α was found elevated (≥8.1) in 68.6% of patients, while high hs-CRP (≥0.5) in 60.5%. Diabetic patients with high level of inflammation showed significantly higher levels of NOX4 expression at baseline (p=0.0346). Plasma TNF-α had a negative correlation with eNOS expression (-0.5, p=0.015) and hs-CRP with VEGF-A (-0.63, p=0.005). The expression of NOX4 was parallel to that of plasma TNF-α (0.305, p=0.037), especial-ly in DM. Cumulative mortality at 12-month was related to NLR ≥3 (p=0.019) and TNF-α ≥8.1 (p=0.048). The best cut-off point for NLR to predict mortality was 3.4. Conclusions: NOX4 and TNF-α are crucial for the development and complications of lower limb ischemia, especially in DM. hs-CRP could have a negative influence on angiogenesis too. NLR and TNF-α represent suita-ble markers of mortality in CLTI. These results are novel because they connect muscle gene expres-sion and plasma information in patients with advanced PAD, deepening the search of new and ac-curate targets for this condition.

The objective was to study the prevalence of erosive and ulcerative gastroduodenal lesions, bleedings of this localization and the relationship with factors predisposing to them in patients with critical lower limb ischemia and type 2 diabetes mellitus who underwent endovascular intervention for limb revascularization.Methods and materials. The study included 81 patients aged 67.5±6.8 years, hospitalized in the department of vascular surgery with critical lower limb ischemia of atherosclerotic genesis and type 2 diabetes mellitus to perform revascularization by means of transluminal balloon angioplasty with stenting when indicated. In the preoperative period, all patients underwent fibrogastroduodenoscopy, according to the results of which a scoring assessment of the lesion of the gastric mucosa and duodenum was presented.Results. All patients participating in the study were diagnosed with pathology of the gastroduodenal zone: in 95.1 % of the inflammatory nature, in 4.9 % of the ulcer. The relationship between the duration of rest pain, the fact of damage to the mucous membrane of the upper gastrointestinal tract and its severity was not revealed, but the relationship of erosive and ulcerative lesions of the stomach and duodenum with the number of taken pain pills was determined. In patients with repeated endovascular intervention and / or amputation, gastrointestinal bleedings were more often recorded compared with study participants who underwent a single revascularization – 11.1 and 1.6 % of patients, respectively.Conclusion. Erosive and ulcerative lesions of varying severity are present in all patients with critical lower limb ischemia on the background of diabetes mellitus. At the same time, patients with repeated endovascular interventions and / or amputations are more susceptible to bleeding. For the prevention of pathology of the stomach and duodenum, an in-depth diagnosis and a differentiated approach are required.

Abstract Background Patients with a history of peripheral arterial disease (PAD) undergoing coronary artery bypass grafting (CABG) exhibit higher rates of complications. There are conflicting data on the survival benefits for bilateral thoracic artery (BITA) grafting compared with left internal thoracic artery (LITA) CABG in patients with PAD. The aim of the study was to explore the influence of the use of BITA grafts vs. LITA for CABG on post-operative acute lower limb ischemia (ALLI) and main post-operative complications in patients with concomitant PAD. Methods We used a propensity-score (PS) based analysis to compare outcomes between the two surgical procedures, BITA and LITA. The inverse probability of treatment weighting PS technique was applied to adjust for pre- and intra-operative confounders, and to get optimal balancing of the pre-operative data. The primary outcome was the estimate of postoperative ALLI. Secondary outcomes included overall death and death of cardiac causes within 30 days of surgery, stroke and acute kidney disease (AKD). Results The study population consisted of 1961 patients. The LITA procedure was performed in 1768 patients whereas 193 patients underwent a BITA technique. The estimate of ALLI was 14% higher in the BITA compared to the LITA (p < 0.001) group. Thirty-day mortality, cardiac death, occurrence of stroke and AKI did not differ significantly between the groups. Conclusions The use of both ITAs led to a significant increase in ALLI. This result was most likely caused by the complete disruption of the ITA collateral providing additional blood supply to the lower extremities. Based on our data, BITA should be used with extreme caution in PAD patients. Further research on this topic is necessary to confirm our findings.
