High prevalence of lower limb atherosclerosis is linked with the gut-liver axis in patients with primary biliary cholangitis.

BACKGROUND AND AIMS: Hypercholesterolemia is frequent in people with primary biliary cholangitis (PBC); however, it does not seem to confer an increased risk of cardiovascular disease. We aimed to evaluate the prevalence of peripheral arterial disease in PBC women and its association with the gut-liver axis and systemic inflammation. METHODS: Thirty patients affected by PBC and hypercholesterolemia were enrolled, with equal-sized groups of women with non-alcoholic fatty liver disease (NAFLD) and healthy controls (CTRL). All patients underwent Doppler ultrasound examination of peripheral arteries, assessment of flow-mediated dilation, quantification of circulating cytokines and vasoactive mediators and characterization of the gut microbiota. RESULTS: PBC patients had a higher prevalence of lower extremity arterial disease (LEAD) defined as atherosclerotic plaques in any of femoral, popliteal and/or tibial arteries compared with both NAFLD and CTRL women (83.3% vs. 53.3% and 50%, respectively; p = .01). Factors associated with LEAD at univariate analysis were VCAM-1 (p = .002), ICAM-1 (p = .003), and TNF-alpha (p = .04) serum levels, but only VCAM-1 (OR 1.1, 95% CI 1.0-1.1; p = .04) and TNF-alpha (OR 1.12, 95% CI 0.99-1.26; p = .04) were confirmed as independent predictors in the multivariate model. Gut microbiota analysis revealed that Acidaminococcus (FDR = 0.0008), Bifidobacterium (FDR = 0.001) and Oscillospira (FDR = 0.03) were differentially expressed among groups. Acidaminococcus, which was increased in PBC, was positively correlated with TNF-alpha serum levels. Down-regulation of metabolic pathways linked to fatty acid and butyrate metabolism, glyoxylate metabolism and branched-chain amino acids degradation was found in the functional gut metagenome of PBC women. CONCLUSIONS: LEAD is common in patients affected by PBC and is associated with inflammatory markers and alterations in the gut-liver axis.

Gut Microbiota and Cardiovascular Disease: Evidence on the Metabolic and Inflammatory Background of a Complex Relationship.

Several studies in recent years have demonstrated that gut microbiota-host interactions play an important role in human health and disease, including inflammatory and cardiovascular diseases. Dysbiosis has been linked to not only well-known inflammatory diseases, such as inflammatory bowel diseases, rheumatoid arthritis, and systemic lupus erythematous, but also to cardiovascular risk factors, such as atherosclerosis, hypertension, heart failure, chronic kidney disease, obesity, and type 2 diabetes mellitus. The ways the microbiota is involved in modulating cardiovascular risk are multiple and not only related to inflammatory mechanisms. Indeed, human and the gut microbiome cooperate as a metabolically active superorganism, and this affects host physiology through metabolic pathways. In turn, congestion of the splanchnic circulation associated with heart failure, edema of the intestinal wall, and altered function and permeability of the intestinal barrier result in the translocation of bacteria and their products into the systemic circulation, further enhancing the pro-inflammatory conditions underlying cardiovascular disorders. The aim of the present review is to describe the complex interplay between gut microbiota, its metabolites, and the development and evolution of cardiovascular diseases. We also discuss the possible interventions intended to modulate the gut microbiota to reduce cardiovascular risk.

The Relationship between Post-COVID Syndrome and the Burden of Comorbidities Assessed Using the Charlson Comorbidity Index.

Introduction: The post-COVID-19 syndrome is a clinical entity characterized by the manifestation of signs and symptoms that develop after the acute phase of COVID-19, which persist for a duration of more than 12 weeks and are not explained by any alternative diagnosis. It has been observed that individuals with pre-existing chronic diseases, including cardiovascular and pulmonary diseases, are at a greater risk of developing post-COVID-19 syndrome. The Charlson Comorbidity Index (CCI) is a useful tool employed to evaluate the burden of comorbidities and predict the prognosis of patients with post-COVID-19 syndrome. The present study aims to assess whether the burden of comorbidities, evaluated using the CCI, correlates with post-COVID-19 syndrome. Materials and Methods: Between 21 April 2020 and 15 May 2023, we enrolled all consecutive outpatients with previous COVID-19 admissions to a post-acute day-hospital service three months after a negative SARS-CoV-2 molecular test. We assessed age, sex, BMI, acute COVID-19 and post-COVID-19 signs, and symptoms and calculated CCI according to its current definition. Post-COVID-19 syndrome was defined as the persistence of at least one sign or symptom lasting more than 12 weeks after COVID-19 resolution and not explained by an alternative diagnosis. The relationship between post-COVID-19 and CCI was explored first with the chi-squared test, then with different binary logistic regression models. We considered significant values of p lower than 0.05. Results: We obtained a cohort of 3636 patients and observed a significant association between the number of post-COVID-19 symptoms and CCI. Patients developing post-COVID-19 were more commonly affected by a greater burden of comorbidities. Patients with at least one CCI point had an increased risk of post-COVID-19 syndrome (OR:2.961; 95%CI: 2.269-3.863; p < 0.0001), which increased further for CCI ≥ 4 (OR:6.062; 95%CI: 3.163-11.618; p < 0.0001). Conclusions: Patients affected by post-COVID-19 show a greater clinical complexity and a larger burden of comorbidities, synthesized by a higher CCI; moreover, a higher CCI seems to correlate with an increasing post-COVID-19 risk, being the presence of ≥1 or ≥4 CCI points associated with a 3-fold and 6-fold increased risk of post-COVID-19 syndrome, respectively.

Asymptomatic and symptomatic deep venous thrombosis in hospitalized acutely ill medical patients: risk factors and therapeutic implications.

BACKGROUND: Acutely ill medical patients experience deep venous thrombosis (DVT) during the hospitalization, however the time course of DVT is still unclear. OBJECTIVES: To evaluate risk factors in acutely ill hospitalized medical patients for proximal asymptomatic DVT (ADVT) and symptomatic DVT (SDVT) at admission and discharge. PATIENTS/METHODS: In this prospective observational study, consecutive acutely ill medical patients (hospitalized mainly for acute medical disease as infections, neoplasm, anemia, heart failure) underwent compression ultrasonography (CUS) of proximal lower limb veins within 48 h from admission and at discharge to diagnose ADVT and SDVT. Covid-19 patients, anticoagulant therapy, surgical procedures, acute SDVT, and acute pulmonary embolism, were exclusion criteria. Biographical characteristics at hospitalization, D-Dimer (assessed by ELISA)) and DD-improve score. RESULTS: Of 2,100 patients (1002 females, 998 males, age 71 ± 16 years) 58 (2.7%) had proximal ADVT at admission. Logistic regression analysis showed that age, and active cancer were independently associated with ADVT at admission. The median length of hospitalization was 10 days [interquartile range: 6-15]. During the hospital stay, 6 patients (0.3%) with a negative CUS at admission experienced DVT (2 SDVT and 4 ADVT). In the subgroup of patients (n = 1118), in whom D-dimer was measured at admission, D-Dimer and IMPROVE-DD score were associated with ADVT at admission (n = 37) and with all DVT (n = 42) at discharge. ROC curve defined an IMPROVE-DD score of 2.5 as the optimal cut-off for discriminating patients with and without thrombotic events. CONCLUSIONS: We provide evidence of early development of ADVT in unselected acutely ill medical patients suggesting the need of investigating patients by CUS immediately after hospital admission (within 48 h). Advanced age, active cancer, known thrombophilia and increased IMPROVE-DD score may identify patients at risk. The benefit of anticoagulation needs to be investigated in patients with these specific risk factors and negative CUS at admission. TRIAL REGISTRATION: NCT03157843.

Sortilin levels correlate with major cardiovascular events of diabetic patients with peripheral artery disease following revascularization: a prospective study.

BACKGROUND: Peripheral artery disease (PAD) represents one of the most relevant vascular complications of type 2 diabetes mellitus (T2DM). Moreover, T2DM patients suffering from PAD have an increased risk of major adverse cardiovascular events (MACE) and major adverse limb events (MALE). Sortilin, a protein involved in apolipoproteins trafficking, is associated with lower limb PAD in T2DM patients. OBJECTIVE: To evaluate the relationship between baseline serum levels of sortilin, MACE and MALE occurrence after revascularization of T2DM patients with PAD and chronic limb-threatening ischemia (CLTI). RESEARCH DESIGN AND METHODS: We performed a prospective non-randomized study including 230 statin-free T2DM patients with PAD and CLTI. Sortilin levels were measured before the endovascular intervention and incident outcomes were assessed during a 12 month follow-up. RESULTS: Sortilin levels were significantly increased in individuals with more aggressive PAD (2.25 ± 0.51 ng/mL vs 1.44 ± 0.47 ng/mL, p < 0.001). During follow-up, 83 MACE and 116 MALE occurred. In patients, who then developed MACE and MALE, sortilin was higher. In particular, 2.46 ± 0.53 ng/mL vs 1.55 ± 0.42 ng/mL, p < 0.001 for MACE and 2.10 ± 0.54 ng/mL vs 1.65 ± 0.65 ng/mL, p < 0.001 for MALE. After adjusting for traditional atherosclerosis risk factors, the association between sortilin and vascular outcomes remained significant in a multivariate analysis. In our receiver operating characteristics (ROC) curve analysis using sortilin levels the prediction of MACE incidence improved (area under the curve [AUC] = 0.94) and MALE (AUC = 0.72). CONCLUSIONS: This study demonstrates that sortilin correlates with incidence of MACE and MALE after endovascular revascularization in a diabetic population with PAD and CLTI.

Association between omentin-1 and major cardiovascular events after lower extremity endovascular revascularization in diabetic patients: a prospective cohort study.

BACKGROUND: Cardiovascular complications represent the major cause of morbidity and mortality of type 2 diabetes mellitus (T2DM) patients. In particular, peripheral artery disease (PAD) represents a frequent T2DM vascular complication and a risk factor for the development of major adverse cardiovascular events (MACE). Among adipokines, omentin-1 serum levels are reduced in T2DM patients with PAD and are inversely related to disease severity. OBJECTIVE: To study the relationship between omentin-1 levels, at baseline, with outcomes after endovascular procedures in T2DM patients with PAD and chronic limb-threatening ischemia (CLTI). RESEARCH DESIGN AND METHODS: We enrolled for our prospective non-randomized study, 207 T2DM patients with PAD and CLTI, requiring revascularization. Omentin-1 serum levels were collected before revascularization and patients incidence outcomes were evaluated at 1, 3, 6 and 12 months. RESULTS: Omentin-1 was reduced in patients with more severe disease (27.24 ± 4.83 vs 30.82 ± 5.48 ng/mL, p < 0.001). Overall, 84 MACE and 96 major adverse limb events (MALE) occurred during the 12-month follow-up. We observed that omentin-1 levels were lower in patients with MACE (26.02 ± 4.05 vs 31.33 ± 5.29 ng/mL, p < 0.001) and MALE (26.67 ± 4.21 vs 31.34 ± 5.54 ng/mL, p < 0.001). The association between omentin-1, MACE and MALE remained significant after adjusting for major risk factors in a multivariate analysis. Receiver operating characteristics (ROC) curve using omentin-1 levels predicted incidence events (area under the curve = 0.80). CONCLUSIONS: We demonstrated that reduced omentin-1 levels, at baseline, are related with worse vascular outcomes in T2DM patients with PAD and CLTI undergoing an endovascular procedure.

Upper extremity deep vein thrombosis treated with direct oral anticoagulants: a multi-center real world experience.

Upper-extremity deep vein thrombosis (UEDVT) accounts for about 5-10% of all cases of deep vein thrombosis (DVT). It is often associated with cancer and/or presence of a central venous catheter (CVC), but it may also occur in the absence of these favoring conditions. The safety and efficacy of using direct oral anticoagulants (DOACs) in subjects with UEDVT has not been systematically evaluated and the only data available in the literature derive from anecdotal evidence, analysis of registries, and small single-centre studies. In addition, a specific analysis of UEDVT not associated with cancer and/or CVC has never been made. In this study, we specifically focused on patients with no cancer and without a CVC who were diagnosed with a first episode of UEDVT and were treated with a DOAC. We studied 61 patients, treated in six Italian centres between January 2014 and December 2018. Treatment lasted at least 3 months in all patients. In terms of efficacy, no recurrence of thrombosis or pulmonary embolism were recorded, while Doppler ultrasonography, performed after at least three months of treatment, documented in all cases either partial or complete recanalization of obstructed veins. In terms of safety, no cases of major bleedings were recorded. This is the only series available in the literature of patients treated with DOACs for UEDVT not associated with cancer and/or CVC. This small multicenter real world experience supports the concept that DOACs might be safe and effective for treating UEDTV. Further studies are required to better understand the role of DOACs in these patients.

Sortilin levels are associated with peripheral arterial disease in type 2 diabetic subjects.

BACKGROUND: Sortilin is a 95-kDa protein which has recently been linked to circulating cholesterol concentration and lifetime risk of developing significant atherosclerotic disease. Sortilin is found inside different cell types and circulating in blood. Higher circulating sortilin concentration has been found in patients with coronary atherosclerosis compared to control subjects. Sortilin concentration is influenced by statin therapy. METHODS: We enrolled statin-naïve subjects with type 2 diabetes mellitus and we performed a cross-sectional study to evaluate the association between sortilin levels and the presence of clinically significant lower limb peripheral artery disease (PAD) in a population of statin-free diabetic subjects. RESULTS: Out of the 154 patients enrolled in our study, 80 patients were free from PAD, while 74 had clinically significant PAD. Sortilin concentration was significantly higher in the latter group compared to the former (1.61 ± 0.54 ng/mL versus 0.67 ± 0.30 ng/mL, P < 0.01) and there was a trend toward increased sortilin levels as disease severity increased. The association of sortilin levels with PAD remained after adjusting for major risk factors in a multivariate analysis. CONCLUSIONS: We showed that sortilin is significantly and independently associated with the presence of lower limb PAD in a statin-free diabetic population and it may be a promising marker for clinically significant atherosclerosis of the lower limbs. Further studies are needed to confirm this finding and to evaluate its clinical usefulness.

Association between plasma omentin-1 levels in type 2 diabetic patients and peripheral artery disease.

BACKGROUND: Type-2 diabetes mellitus is one of the major risk factors of atherosclerosis, particularly in peripheral artery disease (PAD). Several studies have documented a correlation between omentin-1 serum levels, atherosclerosis, and cardiovascular diseases. However, a clear link between circulating omentin-1 and PAD in diabetic patients has yet to be established. The aim of this study was to investigate the potential role of omentin-1 in PAD in type-2 diabetic patients. METHODS: In this cross-sectional study, we analyzed omentin-1 serum levels by ELISA in 600 type-2 diabetic patients with (n = 300) and without (n = 300) PAD at Fontaine's stage II, III, or IV. RESULTS: We found that omentin-1 serum levels were significantly lower in diabetic patients with PAD than in diabetic controls (29.46 vs 49.24 ng/mL, P < 0.001) and that the levels gradually decreased in proportion to disease severity (P < 0.05). The association between omentin-1 levels and PAD remained significant after adjusting for major risk factors in a multivariate analysis. CONCLUSIONS: Our results suggest that omentin-1 is reduced in type 2 diabetic patients with PAD and that omentin-1 levels are related to disease severity.

Endometriosis and atherosclerosis: what we already know and what we have yet to discover.

The possible association between endometriosis and atherosclerosis represents an emerging topic in the field of women's health. In this Clinical Opinion paper, we analyze this theme focusing on the pathogenetic mechanisms of both diseases, deeply discussing about what is already known about this association and producing starting points about what we consider suitable to research in the near future with regard to cardiovascular involvement in women affected by endometriosis. We have identified 5 reports specifically carried out to investigate the relationship between atherosclerosis and endometriosis; these studies show the presence of subclinical atherosclerosis in women affected by endometriosis, susceptible of regression after surgical removal of endometriosis, with a possible prognostic relevance for variations of cardiovascular risk in these women. However, to date, no studies in literature have been carried out to investigate the real incidence of cardiovascular events in women with endometriosis.

Regression of endothelial dysfunction in patients with endometriosis after surgical treatment: a 2-year follow-up study.

STUDY QUESTION: How does endothelial function change in women with endometriosis after surgical treatment? SUMMARY ANSWER: Surgical treatment of endometriosis leads to endothelial function improvement, resulting in reduction of cardiovascular risk. WHAT IS KNOWN ALREADY: Some recent studies have demonstrated that in young women with endometriosis, even if structural alterations are absent, endothelial dysfunction, expressed as flow-mediated dilation (FMD) impairment, can nevertheless occur. However, there are no data about changes of endothelial function in women with endometriosis after surgical treatment of endometriosis. STUDY DESIGN, SIZE, DURATION: This is a follow-up study carried out in 68 women enrolled in a previous study. Endothelial function was evaluated 2 years after surgical procedure and compared with baseline values. PARTICIPANTS/MATERIALS, SETTING, METHODS: Twenty-two patients who had undergone surgical treatment of endometriosis (named as patients with STE) and 10 control subjects without endometriosis, from the original study sample participated in this follow-up study. Assessment of endothelial function by FMD evaluation and measurements of serum markers of endothelial activation and inflammation were done in all these subjects. MAIN RESULTS AND THE ROLE OF CHANCE: After a 2-year follow-up period, FMD increased significantly with respect to baseline values among patients with STE [average pre- to post-difference: 5.07%, 95% confidence intervals (CI) 3.50, 6.63%; P < 0.001] but not among controls (average pre- to post-difference: 1.56%, 95% CI -0.55, 3.67%; P = 0.13). Follow-up FMD values were not significantly different between patients with STE and controls (average difference 1.50%, 95% CI -1.24, 4.23%; P = 0.27). Follow-up markers of inflammation and endothelial cells activation were similar among patients with STE and controls. LIMITATIONS, REASONS FOR CAUTION: Although this study represents the first in the literature assessing endothelial function after surgical treatment of endometriosis, further longitudinal studies are desirable to define better the real risk that women with a history of endometriosis will develop cardiovascular events. WIDER IMPLICATIONS OF THE FINDINGS: Endothelial dysfunction may be a better predictor of future cardiovascular events than traditional risk factors and the improvement in endothelial function we observed in patients after STE may have significant implications for their future cardiovascular risk. STUDY FUNDING/COMPETING INTEREST(S): No external funding has been either sought or obtained for this study. There are no conflicts of interest to declare.

Von Willebrand factor hyperactivity affects the outcome of lower limb revascularization in subjects with type 2 diabetes mellitus complicated by diabetic foot vasculopathy: An observational pilot study.

Aim of this study is to evaluate any differences in VWF antigen, VWF activity and ADAMTS-13 activity before and after successful and non-successful Percutaneous Transluminal Angioplasty (PTA) in subjects with type 2 diabetes (T2DM) complicated by Chronic limb-threatening ischemia (CLTI) in diabetic foot vasculopathy. METHODS: In this prospective observational pilot study, we enrolled 35 T2DM subjects who underwent lower limb PTA. Transcutaneous oximetry was performed in all patients before and 6 weeks after PTA. The change in oxygen partial pressure (TcpO2) before and after PTA was expressed as TcpO2-delta (ΔTcpO2). VWF antigen, VWF activity and ADAMTS-13 activity were measured before and 6 weeks after PTA; changes were expressed as delta and ratio from baseline. RESULTS: Subjects with ∆TcpO2 < 15 mmHg presented higher ΔVWF activity (p = 0.050) and lower ADAMTS-13 activity ratio (p = 0.080). Subjects with ∆TcpO2 < 30 mmHg showed lower ADAMTS-13 activity Δ and ratio (p = 0.028). CONCLUSIONS: VWF antigen levels and VWF activity may potentially affect PTA outcome. Higher levels of VWF could derive from VWF release as consequence of PTA-induced mechanical endothelial damage and/or oxidative stress-induced modifications of VWF structure with impairment of VWF-ADAMTS13 interactions.

Association between TNFRSF11B gene polymorphisms and history of ischemic stroke in Italian diabetic patients.

Osteoprotegerin (OPG) is a secretory glycoprotein that belongs to the tumor necrosis factor receptor family and plays a role in atherosclerosis. The present study aimed to evaluate whether OPG gene (TNFRSF11B) polymorphisms are involved in ischemic stroke in an Italian population with diabetes. Participants in a retrospective case-control study included 364 diabetic patients (180 males, 184 females) with history of ischemic stroke and 492 diabetic subjects without history of ischemic stroke (252 males, 240 females). The T245G, T950C, and G1181C polymorphisms of the OPG gene were analyzed by polymerase chain reaction and restriction fragment length polymorphism. We found that the T245G, T950C, and G1181C gene polymorphisms of the OPG gene were significantly (34.1 vs. 9.5 %, P < 0.0001; 30.8 vs. 6.3 %, P < 0.0001 and 26.4 vs. 11.6 % P < 0.0001, respectively) and independently (adjusted OR 5.15 [3.46-7.68], OR 6.63 [4.26-10.31], and OR 3.03 [2.04-4.50], respectively) associated with history of ischemic stroke. We also found that these three polymorphisms act synergistically in patients with stroke history. The TNFRSF11B gene polymorphisms studied are associated with history of ischemic stroke and synergistic effects between these genotypes might be potential markers for cerebrovascular disorders.

Role of Endothelium in Cardiovascular Sequelae of Long COVID.

The global action against coronavirus disease 2019 (COVID-19), caused by SARS-CoV-2 infection, shed light on endothelial dysfunction. Although SARS-CoV-2 primarily affects the pulmonary system, multiple studies have documented pan-vascular involvement in COVID-19. The virus is able to penetrate the endothelial barrier, damaging it directly or indirectly and causing endotheliitis and multi-organ injury. Several mechanisms cooperate to development of endothelial dysfunction, including endothelial cell injury and pyroptosis, hyperinflammation and cytokine storm syndrome, oxidative stress and reduced nitric oxide bioavailability, glycocalyx disruption, hypercoagulability, and thrombosis. After acute-phase infection, some patients reported signs and symptoms of a systemic disorder known as long COVID, in which a broad range of cardiovascular (CV) disorders emerged. To date, the exact pathophysiology of long COVID remains unclear: in addition to the persistence of acute-phase infection mechanisms, specific pathways of CV damage have been postulated, such as persistent viral reservoirs in the heart or an autoimmune response to cardiac antigens through molecular mimicry. The aim of this review is to provide an overview of the main molecular patterns of enduring endothelial activation following SARS-CoV-2 infection and to offer the latest summary of CV complications in long COVID.

Prevention and treatment of catheter-related venous thrombosis in long-term parenteral nutrition: A SINuC position statement.

The implementation of long-term parenteral nutrition (PN) often requires the placement of central venous access, a procedure that carries a considerable risk of catheter-related venous thrombosis (CRT). The occurrence of CRT represents a major event in the natural history of patients in PN since it can lead to central venous access loss and PN failure. Despite the importance of this topic in clinical nutrition, the prevention and treatment of CRT in PN represents one of the "gray areas" of the literature of the presence of few randomized controlled clinical trials and the generally low level of evidence of published scientific papers. Through a narrative review of the literature and a Delphi consensus, the Italian Society of Clinical Nutrition and Metabolism (SINuC) aimed to collect some practical recommendations regarding the current state-of-the-art in the prevention, diagnosis, and treatment of CRT in patients undergoing long-term PN.

Sex-Based Differences in Clinical Characteristics and Outcomes among Patients with Peripheral Artery Disease: A Retrospective Analysis.

Peripheral arterial disease (PAD) is a prevalent medical condition associated with high mortality and morbidity rates. Despite the high clinical burden, sex-based differences among PAD patients are not well defined yet, in contrast to other atherosclerotic diseases. This study aimed to describe sex-based differences in clinical characteristics and outcomes among hospitalized patients affected by PAD. This was a retrospective study evaluating all patients with a diagnosis of PAD admitted to the Emergency Department from 1 December 2013 to 31 December 2021. The primary endpoint of the study was the difference between male and female PAD patients in cumulative occurrence of Major Adverse Cardiovascular Events (MACEs) and Major Adverse Limb Events. A total of 1640 patients were enrolled. Among them, 1103 (67.3%) were males while females were significantly older (median age of 75 years vs. 71 years; p =< 0.001). Females underwent more angioplasty treatments for revascularization than men (29.8% vs. 25.6%; p = 0.04); males were treated with more amputations (19.9% vs. 15.3%; p = 0.012). A trend toward more MALEs and MACEs reported in the male group did not reach statistical significance (OR 1.27 [0.99-1.64]; p = 0.059) (OR 0.75 [0.50-1.11]; p = 0.153). However, despite lower extremity PAD severity seeming similar between the two sexes, among these patients males had a higher probability of undergoing lower limb amputations, of cardiovascular death and of myocardial infarction. Among hospitalized patients affected by PAD, even if there was not a sex-based significant difference in the incidence of MALEs and MACEs, adverse clinical outcomes were more common in males.

Endothelial dysfunction but not increased carotid intima-media thickness in young European women with endometriosis.

BACKGROUND: Atherosclerosis is a chronic and degenerative disease developing typically in the elderly; nonetheless, a condition of accelerated atherosclerosis can be observed precociously in the presence of some diseases. Endometriosis, a chronic benign gynecological disorder, shows some characteristics, such as oxidative stress, systemic inflammation and a pro-atherogenic lipid profile, which could increase the risk of developing accelerated atherosclerosis. The aim of our study was to evaluate markers of subclinical atherosclerosis in young European women with endometriosis. METHODS: This cross-sectional study included 37 women with endometriosis and 31 control subjects. The presence of subclinical atherosclerosis was investigated by ultrasound evaluation of common carotid intima-media thickness (ccIMT) and flow-mediated dilation (FMD); in addition, serum levels of lipids, inflammatory and coagulation parameters, as well as markers of endothelial inflammation and activation, were determined. RESULTS: Women with endometriosis showed significantly lower values of FMD compared with controls [mean difference: -4.62, 95% confidence interval (CI): -6.52, -2.73; P < 0.001], whereas no significant differences in ccIMT values were found between the two groups. As regards markers of endothelial inflammation and activation, women with endometriosis had significantly higher values of inter-cellular adhesion molecule 1 (P < 0.001), vascular cell adhesion molecule 1 (P < 0.001), E-selectin (P < 0.001), von Willebrand factor (P = 0.004) and ristocetin cofactor (P = 0.001) compared with controls. CONCLUSIONS: Our study suggests that women with endometriosis have more subclinical atherosclerosis, resulting in a higher risk of developing cardiovascular disorders. Moreover, our findings demonstrate that endothelial dysfunction can occur in the absence of structural atherosclerotic changes; its evaluation might be helpful in young women with endometriosis.

Delphi case: Sharing of clinical experiences for improvement in the treatment of chronic venous disease.

Chronic venous disease (CVD) is a common condition with major health consequences that is associated with poor long-term prognosis, significant socioeconomic impact, disabling symptoms, and reduced quality of life. To provide a novel evidence-based approach in the management of CVD, a consensus process ("Delphi Case") following a first Delphi Consensus was conceived. With a real-life fashion analysis, a steering committee formed by 3 expert leaders on chronic venous disease drove a panel of 77 expert Italian angiologists/vascular surgeons along a collegial discussion, integrating data coming from the guidelines recommendations of different Vascular Scientific Societies with the consensus agreement statements gathered from the first Delphi Consensus, and with data coming from the discussion of few statements in which there was disagreement. From July 15 to October 16, 2020, demographic, anamnestic, objective, and therapeutic data coming from a total of 2,275 patients were collected by the experts panel using a predefined case report form. The results of this second consensus provided a real-life picture of CVD management in the Italian population and clearly showed that a tailored therapeutic approach together with an appropriate lifestyle (e.g., diet, physical activity, weight loss) must be considered as the milestones for the CVD-related signs and symptoms clinical improvement in daily clinical practice. An evaluation of the adherence and of the efficacy of the prescribed pharmacological and compressive treatment in a medium-long term follow-up of the study population has been planned as the last step of this course and will be object of a future final publication.

Sortilin/Omentin-1 ratio in peripheral artery disease: A cross-sectional study on 295 unselected elderly patients.

BACKGROUND: The role of sortilin and omentin-1 in the pathogenesis of atherosclerosis and vascular disease is an emerging topic in recent years. These molecules can be found circulating in the blood. Recent studies have shown how these biomarkers appear to correlate with the severity of PAD. The levels of these molecules appear to be inversely proportional to each other. Their relationship may provide further insight into the management of the very old diabetic patients with PAD. This study aimed to assess the possible role of sortilin/omentin-1 ratio as easy-to-measure marker in peripheral artery disease (PAD) in type-2 diabetic patients. METHODS: This study analyzed the association between sortilin and omentin-1 serum levels and the presence of clinically significant lower limb PAD in diabetic individuals. We enrolled 295 diabetic patients, including 179 with PAD. Serum levels were collected and correlated with clinical characteristics of the patients. RESULTS: Sortilin concentration was significantly higher in the latter group compared to the former and there was a trend toward increased sortilin levels as disease severity increased. Omentin-1 serum levels were significantly lower in diabetic patients with PAD than in diabetic controls and the levels gradually decreased in proportion to disease severity. The ratio of sortilin to omentin-1 was significantly higher in patients with PAD compared to the other group. CONCLUSION: The sortilin to omentin-1 ratio appears to be a predictive factor for PAD in patients with type-2 diabetes and it may be a promising marker for clinically significant atherosclerosis of the lower limbs. Further studies are needed to confirm this finding and to evaluate its clinical usefulness.
