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.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.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.LEAD is common in patients affected by PBC and is associated with inflammatory markers and alterations in the gut-liver axis.

An immune checkpoint blockade with mAbs to PD-1 and PD-L1 is an expanding therapeutic option for mNSCLC patients. This treatment strategy is based on the use of mAbs able to restore the anti-tumor activity of intratumoral T cells inhibited by PD-1 binding to PD-L1/2 on tumor and inflammatory cells. It has been speculated that a chronic status of systemic inflammation as well as the immunosenescence physiologically occurring in elderly patients may affect the efficacy of the treatment and the occurrence of irAEs. We performed a multi-institutional retrospective study aimed at evaluating the effects of these mAbs (nivolumab or atezolizumab) in 117 mNSCLC patients younger (90 cases) and older (27 cases) than 75 years in correlation with multiple inflammatory parameters (NLR, CRP, ESR, LDH and PCT). No differences were observed when the cohorts were compared in terms of the frequency of PFS, OS, inflammatory markers and immune-related adverse events (irAEs). Similarly, the occurrence of irAEs was strictly correlated with a prolonged OS survival in both groups. On the contrary, a negative correlation between the high baseline levels of inflammatory markers and OS could be demonstrated in the younger cohort only. Overall, PD-1/PD-L1-blocking mAbs were equally effective in young and elderly mNSCLC patients, however, the detrimental influence of a systemic inflammation at the baseline was only observed in young patients, suggesting different aging-related inflammation immunoregulative effects.

Background: Cardiovascular events (CVEs) are the first cause of death in patients with psoriatic arthritis (PsA). Depression is a recognized risk factor in cardiovascular events and is frequently associated with PsA. Flow-mediated dilatation (FMD) is a widely used method for assessing endothelial dysfunction, a parameter with strong prognostic implications for CVEs. The study aims to explore the relationship between FMD, depressive symptoms and serum cytokines in a cohort of patients with PsA.Patients and Methods: FMD was assessed in 50 consecutive PsA patients aged between 30 and 75 years without known cerebrovascular and coronary heart disease or diabetes. Depressive symptoms were reported using the related subscale of the Hospital Anxiety and Depression Scale (HDS). Disease features, activity indexes, and adjusted Framingham risk score (aFRS) were calculated. Serum level of IL-6, TNF-α, and IL-17A were also assessed.Results: In PsA patients (age 50.7 ± 10.2 years, male 42%, disease duration 5.9 ± 3.3 years, Disease Activity in PSoriatic Arthritis (DAPSA) score 14.0 ± 9.4) FMD inversely correlated with the severity of depressive symptoms according to HDS (ρ = −0.339, p = 0.016), age (ρ = −0.507, p = 0.001), aFRS (rs = −0.453, p < 0.001), duration of PsA (ρ = −0.507, p = 0.001), intensity of pain (ρ = −0.507, p = 0.001), and DAPSA (ρ = −0.507, p = 0.001). No statistically significant correlation was found between FMD or HDS and serum cytokines concentrations. HDS predicted FMD in a model adjusted for age, aFRS, PsA duration, and pain intensity (β = −0.271, p = 0.008), with depressive symptoms contributing directly to 6.4% of the variance.Conclusions: Depressive symptoms correlate with endothelial dysfunction with an exposure-response pattern in our cohort of PsA patients.

Minimal hepatic encephalopathy (MHE) is a subclinical complication of liver cirrhosis with a relevant social impact. Thus, there is urgent need to implement easy to use diagnostic tools for the early identification of affected patients. The aim of this study was to investigate cerebral blood flow, systemic hemodynamics as well as endothelial function of cirrhotic patients with MHE, and to verify their change after treatment with rifaximin. Fifty cirrhotic patients with or without MHE and an equal number of healthy controls underwent transcranial Doppler ultrasound (TCD), abdominal Doppler ultrasound (US), and measurement of flow mediated dilation (FMD). In cirrhotic patients diagnosed with MHE receiving rifaximin, the tests were repeated at the end of treatment. Middle (MCA) and posterior (PCA) cerebral artery resistive (RI) and pulsatility (PI) indices were higher in cirrhotic patients than controls, as well as renal and splenic artery RI. Conversely, FMD was reduced. MCA-RI and PI were even higher in cirrhotic patients with MHE compared to those without; a MCA-RI cut-off of 0.65 showed an accuracy of 74% in discriminating the presence of MHE, with 65% sensitivity and 76% specificity. Rifaximin treatment showed no efficacy in the modulation of cerebral vascular flow. In conclusion, cirrhotic patients with MHE have significantly increased cerebral vascular resistances that are not improved by rifaximin treatment. MCA-RI measurement has a good accuracy for the diagnosis of MHE and can be useful for the early identification of this harmful complication of liver cirrhosis.

Background The severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2) has a tropism for the gastrointestinal tract and several studies have shown an alteration of the gut microbiota in hospitalized infected patients. However, long-term data on microbiota changes after recovery are lacking. Methods We enrolled 30 patients hospitalized for SARS‑CoV‑2-related pneumonia. Their gut microbiota was analyzed within 48 h from the admission and compared with (1) that of other patients admitted for suspected bacterial pneumonia (control group) (2) that obtained from the same subject 6 months after nasopharyngeal swab negativization. Results Gut microbiota alpha-diversity increased 6 months after the resolution of SARS-CoV-2 infection. Bacteroidetes relative abundance was higher (≈ 36.8%) in patients with SARS-CoV-2, and declined to 18.7% when SARS-CoV-2 infection resolved (p = 0.004). Conversely, Firmicutes were prevalent (≈ 75%) in controls and in samples collected after SARS-CoV-2 infection resolution (p = 0.001). Ruminococcaceae, Lachnospiraceae and Blautia increased after SARS-CoV-2 infection resolution, rebalancing the gut microbiota composition. Conclusion SARS-CoV-2 infection is associated with changes in the gut microbiome, which tend to be reversed in long-term period.

Background: Endothelial dysfunction has a role in acute COVID-19, contributing to systemic inflammatory syndrome, acute respiratory distress syndrome, and vascular events. Evidence regarding COVID-19 middle- and long-term consequences on endothelium are still lacking. Our study aimed to evaluate if COVID-19 severity could significantly affect the endothelial function after three months from the acute phase. Methods: We assessed endothelial function in outpatients with previous COVID-19 three months after negative SARS-CoV-2 molecular test by measuring flow-mediated dilation (FMD) in patients categorized according to a four-variable COVID-19 severity scale (“home care”; “hospital, no oxygen”; “hospital, oxygen”; “hospital requiring high-flow nasal canula, non-invasive ventilation, invasive mechanical ventilation, or extracorporeal membrane oxygenation”). FMD difference among COVID-19 severity categories was assessed with analysis of variance; we further clarified the relationship between FMD and previous COVID-19 severity with multivariate logistic models. Results: Among 658 consecutive COVID-19 subjects, we observed a significant linear trend of FMD reduction with the increase of the COVID-19 category (p < 0.0001). The presence of endothelial dysfunction was more frequent among hospitalized patients (78.3%) with respect to home-care patients (21.7%; p < 0.0001). COVID-19 severity was associated with increased endothelial dysfunction risk (OR: 1.354; 95% CI: 1.06–1.71; p = 0.011) at multivariate binary logistic analysis. FMD showed a significant direct correlation with PaO2 (p = 0.004), P/F ratio (p = 0.004), FEV1 (p = 0.008), and 6MWT (p = 0.0001). Conclusions: Hospitalized COVID-19 subjects showed an impaired endothelial function three months after the acute phase that correlated with pulmonary function impairment. Further studies are needed to evaluate if these subjects are at higher risk of developing pulmonary disease or future cardiovascular events.

For survivors of severe COVID-19 disease, having defeated the virus is just the beginning of an uncharted recovery path. What follows after the acute phase of SARS-CoV-2 infection depends on the extension and severity of viral attacks in different cell types and organs. Despite the ridiculously large number of papers that have flooded scientific journals and preprint-hosting websites, a clear clinical picture of COVID-19 aftermath is vague at best. Without larger prospective observational studies that are only now being started, clinicians can retrieve information just from case reports and or small studies. This is the time to understand how COVID-19 goes forward and what consequences survivors may expect to experience. To this aim, a multidisciplinary post-acute care service involving several specialists has been established at the Fondazione Policlinico Universitario A. Gemelli IRCSS (Rome, Italy). Although COVID-19 is an infectious disease primarily affecting the lung, its multi-organ involvement requires an interdisciplinary approach encompassing virtually all branches of internal medicine and geriatrics. In particular, during the post-acute phase, the geriatrician may serve as the case manager of a multidisciplinary team. The aim of this article is to describe the importance of the interdisciplinary approach––coordinated by geriatrician––to cope the potential post-acute care needs of recovered COVID-19 patients.

Sarcopenia, the age-dependent loss of muscle mass and function/strength, is increasingly recognized as a major risk factor for adverse outcomes in frail older people. As such, the skeletal muscle is a relevant target for interventions aimed at preventing or postponing the occurrence of negative health-related events in late life. The association among physical inactivity, insufficient intake of energy and protein, and poor muscle health in older adults suggests that physical exercise and targeted nutritional supplementation may offer substantial therapeutic gain against sarcopenia and its negative correlates. This view is supported by observational studies as well as by small-scale clinical trials. In this review, we summarize the available evidence on the beneficial effects of behavioral interventions on sarcopenia. We also briefly describe how the knowledge gathered so far has been used to design the “Sarcopenia and Physical fRailty IN older people: multicomponenT Treatment strategies” (SPRINTT) project. The randomized clinical trial conducted within SPRINTT will provide robust evidence on the effectiveness of exercise and nutrition at preventing negative outcomes associated with sarcopenia and physical frailty.

Nutritional approaches to improve dyslipidemias have been recently developed, but evidences on different medical foods are often incomplete. The main aim of our study was to evaluate the effects on endothelial function, lipid profile, and glucose metabolism of two different combinations of nutraceuticals, first one containing Bergavit (200 mg Citrus bergamia), Omega-3 (400 mg), Crominex 3+ (10 mcg trivalent chromium), and red yeast rice (100 mg; 5 mg monacolin K) and second one containing red yeast rice (200 mg; 3 mg monacolin K), Berberine (500 mg), Astaxanthin (0.5 mg), folic acid (200 mcg), Coenzyme Q10 (2 mg), and Policosanol (10 mg). Fifty subjects affected by dyslipidemia not requiring statin treatment were enrolled in this randomized, blind, controlled trial and submitted to blood sampling for lipid and glucose profiles and instrumental evaluation of endothelial function before and after 6 weeks of treatment with nutraceuticals. Both nutraceutical combinations improved the lipid profile; the nutraceutical containing 5 mg of monacolin K, 200 mg of the extract Citrus bergamia, 400 mg of Omega-3, and 10 mcg of trivalent chromium entailed a significant improvement of endothelial function with enhanced cholesterol lowering effect. In conclusion, this study confirms the positive effect of functional food on lipid profile and endothelial function in absence of major undesirable effects.

Background:Cardiovascular complications are the leading cause of death in patients with psoriatic arthritis (PsA), but current strategies for reducing cardiovascular risk are still inadequate. Depression is a common comorbidity in PsA patients and it is recognized as an independent cardiovascular risk factor in the general population. Endothelial dysfunction, assessed as a reduction in brachial artery Flow Mediated Dilation (FMD), is a predictor of major cardiovascular events in high and low risk populations.Objectives:To investigate the relationship between endothelial function and depressive symptoms in a cohort of patients with PsA.Methods:Sixty consecutive patients with PsA, aged between 30 and 79 years, with no history of major cardiovascular events, were characterized for traditional cardiovascular risk factors and features of psoriatic disease. The risk of cardiovascular events according to traditional risk factors was calculated using the Framingham Risk Score (FRS) and the presence of depressive symptoms was defined through the Hospital Anxiety and Depression Scale (HDS) using the validated cut-off of 8. Endothelial function was assessed by FMD. Serum IL-6 was quantified by ELISA, IL-17 and TNF-α levels by Luminex method.Results:Patients had an average age of 52.1±11.0 years, 43.3% of them were male, 23.3% obese and 25.0% active smokers; 38.3%, 25.0% and 11.7% were treated for high blood pressure, dyslipidemia and diabetes mellitus, respectively. The 10-year risk of major cardiovascular events estimated by FRS was 10.4%. The mean duration of PsA was 9.4 years, 30.0% of patients were in minimal disease activity (MDA) and 61.7% and 46.7% were treated with conventional and biotechnological DMARDs, respectively. The mean HDS value was 6.9±3.2 and 43.4% of patients had significant depressive symptoms. The severity of depressive symptoms according to HDS correlated with disease activity according to DAPSA (r=0.449, p=0.001). The mean FMD was 7.8±3.8%, this value correlated inversely with age (r=-0.408,p2=0.23) and FRS normalized through logarithmic transformation (β=-0.32, p=0.009, R2=0.22).Conclusion:The degree of endothelial dysfunction quantified by FRS correlates with the severity of the depressive symptoms in patients with PsA, independently of the cardiovascular risk attributable to classical risk factors. The weak relationship between FRS and serum levels of IL-6, IL-17 and TNF-alpha suggests a role of factors independent of inflammation in the regulation of endothelial function in patients with PsA. Systematic research and treatment of depressive symptoms could contribute to a more complete stratification and a better management of cardiovascular risk in patients with PsA.Disclosure of Interests:Enrico De Lorenzis: None declared, Angela Di Giorgio: None declared, Gerlando Natalello: None declared, Antonio Nesci: None declared, Dario Bruno: None declared, Donatella Lucchetti: None declared, Giacomo Tanti: None declared, Clara Di Mario: None declared, Pietro Rubortone: None declared, Maria Rosaria Magurano: None declared, Barbara Tolusso: None declared, Angelo Santoliquido: None declared, Giusy Peluso: None declared, Elisa Gremese Consultant of: AbbVie, Bristol-Myers Squibb, Celgene, Eli Lilly, Janssen, Merck Sharp & Dohme, Novartis, Sanofi, UCB, Roche, Pfizer, Speakers bureau: AbbVie, Bristol-Myers Squibb, Celgene, Eli Lilly, Janssen, Merck Sharp & Dohme, Novartis, Sanofi, UCB, Roche, Pfizer

Background Polymyalgia Rheumatica(PMR)is an inflammatory disease that affects people over 50 years old, characterised by pain and functional limitation of shoulder and hip, acute phase reactant elevation and a dramatic response to low doses of steroids. Atherosclerosis is a chronic inflammatory process that affects the arterial vessels of multiple districts. Endothelial dysfunction is an early event of the atherogenic process. Chronic inflammatory diseases have an increased risk of accelerated atherosclerosis and cardiovascular disease. A study on 41 subjects with giant cell arteritis with and without PMR showed an increased mean-intimal thickness, suggesting a pro-atherogenic role of PMR. However there are no studies that evaluated endothelial dysfunction which is a more precocious marker of subclinical atherosclerosis in PMR patients Objectives Aim of the study was to compare endothelial function among PMR patients to a control population. Moreover, the trend of endothelial disfuncion was evaluated over time in relationship to the improvement of clinical, laboratory and instrumental parameters. Methods The study involved 16 treatment-naive patients with a new PMR diagnosis. Every 3 months routine visits were performed;at each visit laboratory and clinical data and the endothelial function at the brachial artery were evaluated. The endothelial function was evaluated at the brachial artery level after 15 min of rest; the brachial artery diameter and the basal flow was measured at baseline and after the positioning of sphygmomanometerfor 5 min to induce the forearm ischemia. The flow was measured again 15 s after deflation of the sleeve and 60–90 s after the diameter of the artery reassessed to obtain flow-mediated dilatation (FMD). The FMD, which represents endothelium-dependent vasodilatation was expressed as percentage increase to the starting diameter after stimulation Results 16 PMR patients(mean age 73.9±5.8, 7 Female)were compared with a population of 16 healthy controls age-matched(70.8±8.1,p=ns). The two groups differed for the values of Erythrocyte Sedimentation Rate(ESR)(61.1±28 vs 19.3±16 mm/h, p At the sixth month of follow-up ESR was 31.2±29,9 mm/h while CRP was 8±5.9 mg/L; at the twelve month of follow-up ESR was 22.7±13.6 and CRP was 9.1±8.2 mg/L In PMR patients group 11 patients had hypertension, 5 dyslipidemia, 1 diabetes and 5 patients were smokers, while in control group 9 had hypertension, 10 dyslipidemia, 6 were smokers and no one had diabetes. Healthy subjects matched by age, sex and comorbidity were chosen as controls. At baseline FMD of patients was lower than controls(6.6±3.4 vs 10.7±2.3, p The FMD values show an inverse correlation with values of ESR(R=−0.42 p=0.019)and CRP(R=−0.56 p=0.001)at baseline. Conclusions Endothelial dysfunction in patients with PMR appears early during the course of the disease and is related to levels of acute phase reactant; steroid therapy gradually improves these values;only after a year of therapy comparable values are observed between patients and healthy controls.

e15057 Background: In the last few years, there has been a renewed interest on the potential use of immunotherapy alone or combined to chemotherapy (CHT) for mCRC patients. GOLFIG regimen (biweekly Gemcitabine+FOLFOX and IL2 and GM-CSF) was designed to enhance immunomodulating effects of selected cytotoxic drugs by combining them with cytokines able to promote priming and effector phases of the immune-response. This regimen has been tested in two different phase II and III clinical trials in mCRC patients, whose successful results have been published. Here we present the results a retrospective analyses including all the patients treated in a period of 16 years. Methods: This is a multi-institutional retrospective study including 179 mCRC patients (106 men, 73 women). They received a median of 12 courses of GOLFIG regimen (treated between June 2002 and November 2018). K-RAS mutational status has also been evaluated in 74 pts (41 wild type and 33 mutated); as for sidedness 112 pts had a left disease and 67 pts right disease; 71 pts received only one previous CHT line and 100 more than two lines. PFS and OS were evaluated by Kaplan-Meier curves and Cox-regression analyses in different subgroups (RAS mutational status, sidedness, previous CHT lines) to estimate their effect on survival endpoints. Results: We recorded a mean PFS and OS of 15,28 [95%CI:10,36-20,20] and 24,61 [95%CI:19,07-30,14] months, respectively, with no difference in efficacy outcomes observed among the different subgroups (one vs. more than one previous CHT lines; left vs. right primary side; k-ras status mutated vs. wt). Finally, we recorded a 2, 5 and 10 year OS-rate, in 42, 17 and 14 percent of the patients, respectively. The occurrence of self-limiting autoimmunity was confirmed as highly predictive of longer survival. Conclusions: These results confirm that GOLFIG regimen has strong efficacy in mCRC pts and may represent a reliable option in pretreated setting without evident effect of known prognostic variants. Such data offer a strong basis for future clinical trials in mCRC patients, where GOLFIG may represent a scaffold for combinatory immunotherapy approaches with immune-checkpoint blocking drugs.

The data concerning the distribution, extent and progression of peripheral arterial disease (PAD), as well as its association with traditional cardiovascular (CV) risk factors, have generally been obtained from studies of patients in advanced stages of the disease undergoing surgical or endovascular treatment. In this study, we have introduced a new semiquantitative ultrasonographic score (ultrasonographic lower limb atherosclerosis (ULLA) score) that is able to categorize lower limb atherosclerotic lesions at all stages of PAD. We then associated these ultrasonographic categories with a CV risk profile. We enrolled 320 consecutive subjects with symptoms suggestive of PAD or with known CV risk factors referring to our angiology unit between 1 July 2014 and 30 June 2015 for ultrasonographic evaluation of the lower limb arteries. Femoropopliteal and run-off segments were categorized together and separately based on their ultrasonographic characteristics. In univariate and multivariate analyses, the ULLA scores were significantly associated with the main CV risk factors, that is, age, male gender, cigarette smoking, arterial hypertension, diabetes, dyslipidemia, sedentary lifestyle, previous CV events and family history of CV disease, and also confirming the specific association of single risk factors with different segments of lower limb arteries. The proposed ULLA score enables a complete evaluation of the entire lower limb atherosclerotic burden, extending the results concerning the association of PAD with CV risk factors to all stages of the disease, including the early stages. It can be feasible that this new score will facilitate better evaluation of the progression of PAD and its prospective role in CV risk stratification.

Animal studies suggest that the gut-brain peptide ghrelin plays an important role in the neurobiology of alcohol dependence (AD). Human studies show an effect of alcohol on ghrelin levels and a correlation between ghrelin levels and alcohol craving in alcoholics. This investigation consisted of two studies. Study 1 was a 12-week study with alcohol-dependent subjects, where plasma ghrelin determinations were assessed four times (T0-T3) and related to alcohol intake and craving [Penn Alcohol Craving Score (PACS) and Obsessive Compulsive Drinking Scale (OCDS)]. Serum growth hormone levels and assessment of the nutritional/metabolic status were also performed. Study 2 was a pilot case-control study to assess ghrelin gene polymorphisms (Arg51Gln and Leu72Met) in alcohol-dependent individuals. Study 1 showed no significant differences in ghrelin levels in the whole sample, while there was a statistical difference for ghrelin between non-abstinent and abstinent subjects. Baseline ghrelin levels were significantly and positively correlated with the PACS score at T1 and with all craving scores both at T2 and T3 (PACS, OCDS, obsessive and compulsive OCDS subscores). In Study 2, although there was a higher frequency of the Leu72Met ghrelin gene polymorphism in alcohol-dependent individuals, the distribution between healthy controls and alcohol dependent individuals was not statistically significant. This investigation suggests that ghrelin is potentially able to affect alcohol-seeking behaviors, such as alcohol drinking and craving, representing a new potential neuropharmacological target for AD.

Several extraintestinal clinical manifestations have been reported in celiac disease (CD). Among them, growing evidence suggests the association between CD and affective and psychiatric disorders. In this review the most frequent affective and psychiatric disorders associated with CD and the possible mechanisms involved in these associations were analyzed. The available data suggest that screening for CD in patients with affective and/or psychiatric symptoms may be useful since these disorders could be the expression of an organic disease rather than primary psychiatric illnesses.
