The term spondyloarthritis (SpA) encompasses a group of interrelated disorders characterised by the involvement of the musculoskeletal system as well as extra-articular manifestations like acute anterior uveitis, psoriasis and inflammatory bowel diseases (IBD). Likewise, IBD may present with various extra-intestinal manifestations among which those involving the musculoskeletal system, namely peripheral and axial SpA are the most common. The identification of patients with both SpA and IBD is of paramount importance in clinical practice since the coexistence of these two entities has been associated with great disability and decreased quality of life. In order to achieve an early diagnosis of IBD-SpA it is instrumental that rheumatologists seek for gastrointestinal symptoms in SpA patients and likewise that gastroenterologists seek for inflammatory musculoskeletal symptoms in patients with IBD. This narrative review aims at critically appraising the available evidence about SpA occurring in IBD patients versus IBD occurring in patients with SpA and at highlighting similarities and differences between the two scenarios., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier B.V.

Background and Aims: Whether the association between very high HDL-cholesterol levels and cardiovascular mortality (CVM) is modulated by some facilitating factors is unclear. Aim of the study was to investigate whether the risk of CVM associated with very high HDL-cholesterol is increased in subjects with hyperuricemia., Methods and Results: Multivariable Cox analyses were made in 18,072 participants from the multicentre URRAH study stratified by sex and HDL-cholesterol category. During a median follow-up of 11.4 years there were 1307 cases of CVM. In multivariable Cox models a J-shaped association was found in the whole population, with the highest risk being present in the high HDL-cholesterol group [>80 mg/dL, adjusted hazard ratio (HR), 1.28; 95%CI, 1.02-1.61; p = 0.031)]. However, a sex-specific analysis revealed that this association was present only in women (HR, 1.34; 95%CI, 1.02-1.77; p = 0.034) but not in men. The risk of CVM related to high HDL-cholesterol was much greater in the women with high uric acid (>0.30 mmol/L, HR 1.61; 95%CI, 1.08-2.39) than in those with low uric acid (HR, 1.17; 95%CI, 0.80-1.72, p for interaction = 0.016). In women older than 70 years with hyperuricemia the risk related to high HDL-cholesterol was 1.83 (95%CI, 1.19-2.80, p < 0.005). Inclusion of BMI in the models weakened the strength of the associations., Conclusion: Our data indicate that very high HDL-cholesterol levels in women are associated with CVM in a J-shaped fashion. The risk of CVM is increased by concomitant hyperuricemia suggesting that a proinflammatory/oxidative state can enhance the detrimental cardiovascular effects associated with high HDL-cholesterol., Competing Interests: Declaration of competing interest The authors declare that they have no conflict of interest., (Copyright © 2022 The Italian Diabetes Society, the Italian Society for the Study of Atherosclerosis, the Italian Society of Human Nutrition and the Department of Clinical Medicine and Surgery, Federico II University.

Since the beginning of the pandemic, numerous risk factors have been associated with SARS-CoV-2 infection and COVID-19 outcomes, such as older age, male sex, and the presence of comorbidities, such as hypertension, obesity, and diabetes. Preliminary data also suggest epidemiological association between SARS-CoV-2 infection and systemic autoimmune disease. For this reason, we investigated if patients affected by autoimmune thyroid disorders (AITD) are at risk of developing SARS-CoV-2 infection or COVID-19 disease. From April to September 2020, we have conducted a telephone survey that included 515 consecutive unselected patients with known thyroid disorders, of which 350 were affected by AITD. All 11 definitive diagnosis of COVID-19 (def-sympt-COVID-19) belonged to the AITD group, while the rest 14 cases highly suspected for COVID-19 (suspect-sympt-COVID-19) were equally detected in both group (7 in AITD and 7 in not-AITD). The overall prevalence of symptomatic COVID-19 (def-sympt-COVID-19 + suspect-sympt-COVID-19), recorded in the 350 AITD population was statistically significant higher compared to that reported in the Italian and Tuscan general population at the same time period of the present survey (18/350 = 5.14% vs 516/100000 = 0.51% [p < 0.001; OR = 10.45, 95% CI 6.45-16.92] and vs 394/100000 = 0.39% [p < 0.001; OR = 13.70, 95% CI 8.44-22.25], respectively). Therefore, our results suggest a higher prevalence of SARS-CoV-2 infection and COVID-19 disease in patients with AITD., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 Elsevier B.V.

Introduction: Systemic sclerosis (SSc) is characterized by a complex etiopathogenesis encompassing both host genetic and environmental -infectious/toxic- factors responsible for altered fibrogenesis and diffuse microangiopathy. A wide spectrum of clinical phenotypes may be observed in patients' populations from different geographical areas. We investigated the prevalence of specific clinical and serological phenotypes in patients with definite SSc enrolled at tertiary referral centres in different Italian geographical macro-areas. The observed findings were compared with those reported in the world literature., Materials and Methods: The clinical features of 1538 patients (161 M, 10.5%; mean age 59.8 ± 26.9 yrs.; mean disease duration 8.9 ± 7.7 yrs) with definite SSc recruited in 38 tertiary referral centres of the SPRING (Systemic sclerosis Progression INvestiGation Group) registry promoted by Italian Society of Rheumatology (SIR) were obtained and clustered according to Italian geographical macroareas., Results: Patients living in Southern Italy were characterized by more severe clinical and/or serological SSc phenotypes compared to those in Northern and Central Italy; namely, they show increased percentages of diffuse cutaneous SSc, digital ulcers, sicca syndrome, muscle involvement, arthritis, cardiopulmonary symptoms, interstitial lung involvement at HRCT, as well increased prevalence of serum anti-Scl70 autoantibodies. In the same SSc population immunusppressive drugs were frequently employed. The review of the literature underlined the geographical heterogeneity of SSc phenotypes, even if the observed findings are scarcely comparable due to the variability of methodological approaches., Conclusion: The phenotypical differences among SSc patients' subgroups from Italian macro-areas might be correlated to genetic/environmental co-factors, and possibly to a not equally distributed national network of information and healthcare facilities., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022.

Few data from randomized clinical trials (RCTs) investigating the efficacy of post-induction strategies after the first-line treatment with anti-Epidermal Growth Factor Receptor (EGFR) in patients with metastatic colorectal cancer (mCRC) are available. A systematic review and metanalysis might therefore be useful to highlight and even strengthen these data. A literature search in Pubmed, Embase, American Society of Clinical Oncology (ASCO) Annual Meetings, ASCO Gastrointestinal Symposia, and European Society for Medical Oncology (ESMO) Congresses was performed. The search included RCTs of patients with mCRC treated with an initial period of cytotoxic chemotherapy (CT) in association with anti-EGFR (ie, panitumumab or cetuximab) as first-line regimen, and then switched to one of the following strategies: observation; maintenance with anti-EGFR, fluoropyrimidine (FP), or both; or continuing the induction regimen until disease progression or unacceptable toxicity. Outcomes of interest included overall survival (OS) and progression-free survival (PFS). The overall effect was pooled using the Mantel-Haenszel method fixed-effect model or the DerSimonian-Laird method random-effect model according to heterogeneity (I 2 ). Analysis was performed on June 9, 2021. 7 studies (all phase II trials), including 1038 patients, were considered eligible for the meta-analysis. In all studies, CT (induction or maintenance with FP) + anti-EGFR until disease progression or unacceptable toxicity prolonged OS (HR = 0.72 [95%CI 0.61-0.86]; P < .01) and PFS (HR = 0.76, 95%CI 0.68-0.85; P < .01) compared to other agents (FP ± bevacizumab) or observation. Subgroup analyses for OS and PFS were performed according to type of maintenance therapy (containing or not containing single-agent anti-EGFR). Within patients evaluable for OS, CT + anti-EGFR combinations continued until disease progression were able to decrease the risk of death by 32% (HR 0.68; 95% CI 0.56-0.84; P < .01) and the risk of progression by 25% (HR 0.75; 95% CI 0.65-0.85; P < .01) over no maintenance or maintenance with anti-EGFR alone. Conversely, combination of CT + anti-EGFR were no better over anti-EGFR with FP in term of OS (HR = 0.81 [95%CI 0.60-1.09]; P = .17) and PFS (HR = 0.81 [95% 0.64, 1.01]; P = .06). Maintenance treatment with anti-EGFR + FP might be regarded as the better option following anti-EGFR based induction treatment in RAS wild-type mCRC, in terms of efficacy. This effect might be particularly amplified in left-sided BRAF wild-type mCRC patients. A higher level of evidence coming from phase III trials is auspicable., (Copyright © 2022 Elsevier Inc.

Background and Aim: The URRAH (URic acid Right for heArt Health) Study has identified cut-off values of serum uric acid (SUA) predictive of total mortality at 4.7 mg/dl, and cardiovascular (CV) mortality at 5.6 mg/dl. Our aim was to validate these SUA thresholds in people with diabetes., Methods and Results: The URRAH subpopulation of people with diabetes was studied. All-cause and CV deaths were evaluated at the end of follow-up. A total of 2570 diabetic subjects were studied. During a median follow-up of 107 months, 744 deaths occurred. In the multivariate Cox regression analyses adjusted for several confounders, subjects with SUA ≥5.6 mg/dl had higher risk of total (HR: 1.23, 95%CI: 1.04-1.47) and CV mortality (HR:1.31, 95%CI:1.03-1.66), than those with SUA <5.6 mg/dl. Increased all-cause mortality risk was shown in participants with SUA ≥4.7 mg/dl vs SUA below 4.7 mg/dl, but not statistically significant after adjustment for all confounders., Conclusions: SUA thresholds previously proposed by the URRAH study group are predictive of total and CV mortality also in people with diabetes. The threshold of 5.6 mg/dl can predict both total and CV mortality, and so is candidate to be a clinical cut-off for the definition of hyperuricemia in patients with diabetes., Competing Interests: Declaration of competing interest All authors declare no conflicts of interest., (Copyright © 2022 The Italian Diabetes Society, the Italian Society for the Study of Atherosclerosis, the Italian Society of Human Nutrition and the Department of Clinical Medicine and Surgery, Federico II University.

Cryoglobulinemic vasculitis (CV) is the most frequent extrahepatic manifestation during HCV-chronic infection. An effective Direct Acting Antiviral-treatment leads to CV clinical response in the majority of CV-patients although symptoms may persist/recur despite a sustained virological response. At present, no standardized clinical predictive factors for disease maintenance/recurrence were proposed, as emerged from a complete literature review we performed and reported. Here we provided a detailed descriptive analysis of a wide population of CV patients treated with DAA-based regimes and followed-up after therapy completion for longer than 72 weeks, in order to identify clinical or laboratory predictors of disease outcome and to optimize the patient management. Together with some baseline symptoms (neuropathy, weakness and sicca syndrome), two newly created scores, CV- and Global Severity Index, emerged as reliable and standardized tools to predict CV clinical response before initiating an antiviral therapy. In addition to predictive parameters previously proposed in the world literature, these novel Indexes could fill an unmet gap in the clinical management of the complex HCV-related CV., (Copyright © 2021 Elsevier B.V.

Infection by the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is responsible for the second pandemic of the XXI century after influenza A in 2009. As of mid-June 2020, more than 4,40,000 fatal cases of SARS-CoV-2-related disease (COVID-19) have occurred worldwide. Besides its prominent expression at the level of the respiratory apparatus, COVID-19 is also characterized by a substantial degree of cardiovascular involvement, both in terms of deterioration of pre-existing conditions, and as the effect of inflammation-facilitated acute events. They include ischemic/inflammatory heart disease, ventricular arrhythmias, conduction disturbances, thrombotic events at the level of the lungs, and systemic activation of the coagulation cascade, configuring the scenario of disseminated intravascular coagulation. Herein, we summarize the main COVID-19 features of relevance for the clinicians in the cardiovascular field. The rationale, concerns, and possible side effects of specific therapeutic measures, including anticoagulants, renin-angiotensin-aldosterone system inhibitors, and anti-inflammatory/antiviral medications applied to the treatment of COVID-19 are also discussed., (Copyright © 2020.

Parvovirus B19 (B19V) has been proposed as a triggering agent for some autoimmune diseases including systemic sclerosis (SSc). In this study, we investigated whether B19V infection in vitro differently activates inflammatory pathways, including those dependent on caspase-1 activation, in monocytes from patients with SSc and healthy controls. We showed that B19V can infect both THP-1 cells and primary monocytes but is not able to replicate in these cells. B19V infection increases the production of tumor necrosis factor-α and induces NLRP3-mediated caspase-1 activation in both THP-1 cells differentiated with phorbol 12-myristate 13-acetate and in monocytes from patients with SSc but not from healthy controls. B19V infection was sufficient for THP-1 to produce mature IL-1β. Monocytes from patients with SSc required an additional stimulus, here represented by lipopolysaccharides, to activate cytokine genes. Following B19V infection, however, lipopolysaccharide-activated monocytes from patients with SSc strongly increased the production of IL-1β and tumor necrosis factor-α. Altogether, these data suggest that viral components might potentiate the response to endogenous and/or exogenous toll-like receptor 4 ligands in monocytes from patients with SSc. The B19V-mediated activation of inflammatory pathways in monocytes might contribute to the disease progression and/or development of specific clinical phenotypes., (Copyright © 2019 The Authors.

The Systolic Blood Pressure Intervention Trial (SPRINT) trial demonstrated the efficacy and safety of targeting a systolic blood pressure of <120 mmHg compared to <140 mmHg in selected hypertensive patients. Some evidence, however, suggests a J-curve for; diastolic blood pressure (DBP) particularly in subjects with cardiovascular (CV) and chronic kidney disease. We evaluated the risk of events in SPRINT with focus on these subgroups according to DBP. Mean DBP (±standard deviation) throughout follow-up time was calculated for each patient. Patients were then categorized into five groups according to mean DBP (<60 mmHg, 60-69 mmHg, 70-79 mmHg [reference], 80-89 mmHg, ≥90 mmHg); hazard ratio for outcomes was assessed overall and in the predefined subgroups. A higher risk for CV events was observed in the lower DBP range overall (hazard ratio 1.46, confidential interval 95% 1.1-1.95, P < .001), but not in the absence of pre-existing CV or renal disease. Indeed, such risk significantly increased above 80 mmHg in patients with CV disease and below 70 mmHg in those with chronic kidney disease for selected outcomes. DBP<70 mmHg particularly affected renal outcomes irrespective of renal status. Different risk profiles according to DBP appear to be related to specific clinical characteristics in SPRINT. These findings require further testing in dedicated trials with appropriate follow-up., (Copyright © 2018 American Society of Hypertension. Published by Elsevier Inc. All rights reserved.)

Objectives: The recent sociopolitical events in the Mediterranean and Middle Eastern areas have significantly impacted international migration flows. As disease prevalence and type are different among western and Afro-Asian countries, physicians dealing with refugees should be aware of their specific health needs. We aimed at evaluating the health status and disease history of refugees at their arrival in the urban area of L'Aquila (Italy)., Study Design: This is a monocentric cross-sectional study., Methods: Refugees hosted at the local reception center in L'Aquila (Italy) between July 2014 and December 2014 were cross-sectionally evaluated for anamnestic, clinical, and laboratory features. A subset of randomly selected participants underwent further assessments (screening for tuberculosis, hepatitis B/C, human immunodeficiency virus, syphilis; ambulatory blood pressure measurement [ABPM]) to better define their health status., Results: Ninety-three adult male refugees (27.34 ± 7.41 years) from Africa (76%) and Asia (24%) were enrolled. Overall, the most prevalent diseases according to the International Statistical Classification of Diseases and Related Health Problems 10th revision affected the digestive tract (15.6%) and musculoskeletal apparatus (14.4%). The analysis by continent of origin did not show significant differences in the distribution of diseases, although a trend toward some differences was observed. African refugees had a significantly greater prevalence of viral hepatitis (hepatitis B virus, P = 0.004; hepatitis C virus, P = 0.007) compared with Asians. Hypertension, as detected by ABPM, was uncommon. No written vaccination history was available., Conclusions: Health issues of our sample of Afro-Asian refugees span both non-communicable and communicable diseases, requiring attention for the safety of the individual and the community. National health systems should provide adequate information and shared guidelines for health professionals regarding identification and management of refugees' health needs., (Copyright © 2018 The Royal Society for Public Health.

Background: Skin ulcers (SU) are one of the most frequent manifestations of systemic sclerosis (SSc). SSc-SU are very painful, often persistent and recurrent; they may lead to marked impairment of patient's activities and quality of life. Despite their severe impact on the whole SSc patient's management, the proposed definition, classification criteria, and therapeutic strategies of SSc-SU are still controversial., Objective: The present study aimed to elaborate a comprehensive proposal of definition, classification, and therapeutic strategy of SSc-SU on the basis of our long-term single center experience along with a careful revision of the world literature on the same topic., Methods: A series of 282 SSc patients (254 females and 28 males; 84% with limited and 16% diffuse cutaneous SSc; mean age of 51.5±13.9SD at SSc onset; mean follow-up 5.8±4.6SDyears) enrolled during the last decade at our Rheumatology Unit were retrospectively evaluated with specific attention to SSc-SU. The SSc-SU were classified in 5 subtypes according to prominent pathogenetic mechanism(s) and localization, namely 1. digital ulcers (DU) of the hands or feet, 2. SU on bony prominence, 3. SU on calcinosis, 4. SU of lower limbs, and 5. DU presenting with gangrene. This latter is a very harmful evolution of both DU of the hands and feet needing a differential diagnosis with critical limb ischemia., Results: During the follow up period, one or more episodes of SSc-SU were recorded in over half patients (156/282, 55%); skin lesions were often recurrent and difficult-to-heal because of local complications, mainly infections (67.3%), in some cases associated to osteomyelitis (19.2%), gangrene (16%), and/or amputation (11.5%). SSc-SU were significantly associated with lower patients' mean age at the disease onset (p=0.024), male gender (p=0.03), diffuse cutaneous subset (p=0.015), calcinosis (p=0.002), telangiectasia (p=0.008), melanodermia (p<0.001), abnormal PAPs (p=0.036), and/or altered inflammation reactant (CRP, p=0.001). Therapeutic strategy of SSc-SU included both systemic and local pharmacological treatments with particular attention to complicating infections and chronic/procedural pain, as well as a number of non-pharmacological measures. Integrated local treatments were often decisive for the SSc-SU healing; they were mainly based on the wound bed preparation principles that are summarized in the acronym TIME (necrotic Tissue, Infection/Inflammation, Moisture balance, and Epithelization). The updated review of the literature focusing on this challenging issue was analyzed in comparison with our experience., Conclusions: The recent advancement of knowledge and management strategies of SSc-SU achieved during the last years lead to the clear-cut improvement of patients' quality of life and reduced long-term disability., (Copyright © 2017 Elsevier B.V.

Background and Objectives: Paricalcitol, a selective vitamin D receptor activator, is used to treat secondary hyperparathyroidism in kidney transplant patients. Experimental and clinical studies in non-transplant kidney disease patients have found this molecule to have anti-inflammatory properties. In this exploratory study, we evaluated the anti-inflammatory profile of paricalcitol in kidney-transplant recipients., Methods: Thirty one kidney transplant recipients with secondary hyperparathyroidism completed 3 months of treatment with oral paricalcitol (1μg/day). Serum concentrations and gene expression levels of inflammatory cytokines in peripheral blood mononuclear cells were analysed at the beginning and end of the study., Results: Paricalcitol significantly decreased parathyroid hormone levels with no changes in calcium and phosphorous. It also reduced serum concentrations of interleukin (IL)-6 and tumour necrosis factor-alpha (TNF-α) by 29% (P<0.05) and 9.5% (P<0.05) compared to baseline, respectively. Furthermore, gene expression levels of IL-6 and TNF-α in peripheral blood mononuclear cells decreased by 14.1% (P<0.001) and 34.1% (P<0.001), respectively. The ratios between pro-inflammatory cytokines (TNF-α and IL-6) and anti-inflammatory cytokines (IL-10), both regarding serum concentrations and gene expression, also experienced a significant reduction., Conclusions: Paricalcitol administration to kidney transplant recipients has been found to have beneficial effects on inflammation, which may be associated with potential clinical benefits., (Copyright © 2017 Sociedad Española de Nefrología.

Background: Cardiovascular diseases (CVD) are the first cause of death and disability in western countries. Despite therapeutic advances, their prevalence is constantly increasing. Detailed assessment of modifiable CV risk factors could improve CVD prevention and management., Methods: to assess CV risk and hypertension control in a sample of the Italian population, individuals participating to the 2015 "World Hypertension Day" were interviewed in 62sites all over Italy. Blood pressure was measured with a validated auscultatory or oscillometric device and information on demography and prevalence of CVD risk factors was collected by an anonymous questionnaire. An ad-hoc modified version of the Systematic COronary Risk Evaluation (SCORE) system was then applied., Results: 8657 recruited individuals (43%women, aged 56.68±16years) were subdivided into 3 age groups (40-49y, 50-59y, 60-69y) for analysis. CV risk was low in 62.4%, 18.0% and 0%; moderate in 26.0%, 66.0% and 62.5%; high/very high in 11.6%, 16% and 37.4%, respectively. Smoking was mainly responsible for increased CV risk among those aged 40-49y (26%smokers), while hypertension was the main factor in the whole sample and in subjects over 50y (36% and 42% respectively). Overall, BP control was unsatisfactory in 36% of individuals (28%, 48% and 31% of those who declared to be normotensive, hypertensive on treatment or unaware of their BP condition, respectively)., Conclusions: In this sample of the Italian population, CV risk was alarmingly high, irrespectively of age, mostly due to presence of modifiable risk factors, including hypertension, which should thus be better addressed, especially in the youngsters., (Copyright © 2017.

Hepatitis C virus (HCV) is both hepatotrophic and lymphotropic virus that causes liver as well extrahepatic manifestations including cryoglobulinemic vasculitis, the most frequent and studied condition, lymphoma, and neurologic, cardiovascular, endocrine-metabolic or renal diseases. HCV-extrahepatic manifestations (HCV-EHMs) may severely affect the overall prognosis, while viral eradication significantly reduces non-liver related deaths. Different clinical manifestations may coexist in the same patient. Due to the variety of HCV clinical manifestations, a multidisciplinary approach along with appropriate therapeutic strategies are required. In the era of interferon-free anti-HCV treatments, international recommendations for the therapeutic management of HCV-EHMs are needed. This implies the need to define the best criteria to use antivirals and/or other therapeutic approaches. The present recommendations, based on qualified expert experience and specific literature, will focus on etiological (antiviral) therapies and/or traditional pathogenetic treatments that still maintain their therapeutic utility., (Copyright © 2017 The Authors.

Punica granatum L. (Pomegranate) has been claimed to provide several health benefits. Pomegranate juice is a polyphenol-rich fruit juice with high antioxidant capacity. Several studies suggested that pomegranate juice can exert antiatherogenic, antioxidant, antihypertensive, and anti-inflammatory effects. Nevertheless, the potential cardioprotective benefits of pomegranate juice deserve further clinical investigation. To systematically review and meta-analyze available evidence from randomized placebo-controlled trials (RCTs) investigating the effects of pomegranate juice consumption and blood pressure (BP). A comprehensive literature search in Medline and Scopus was carried out to identify eligible RCTs. A meta-analysis of eligible studies was performed using a random-effects model. Quality assessment, sensitivity analysisand publication bias evaluations were conducted using standard methods. Quantitative data synthesis from 8 RCTs showed significant reductions in both systolic [weighed mean difference (WMD): -4.96mmHg, 95% CI: -7.67 to -2.25, p<0.001) and diastolic BP (WMD: -2.01mmHg, 95% CI: -3.71 to -0.31, p=0.021) after pomegranate juice consumption. Effects on SBP remained stable to sensitivity analyses. Pomegranate juice reduced SBP regardless of the duration (>12 wks: WMD=-4.36mmHg, 95% CI: -7.89 to -0.82, p=0.016) and <12 wks: WMD=-5.83 mmHg, 95% CI: -10.05 to -1.61, p=0.007) and dose consumed (>240cc: WMD=-3.62mmHg, 95% CI: -6.62 to -0.63, p=0.018) and <240cc: WMD=-11.01mmHg, 95% CI: -17.38 to -4.65, p=0.001, pomegranate juice per day) whereas doses >240cc provided a borderline significant effect in reducing DBP. The present meta-analysis suggests consistent benefits of pomegranate juice consumption on BP. This evidence suggests it may be prudent to include this fruit juice in a heart-healthy diet., (Copyright © 2016 Elsevier Ltd. All rights reserved.)

Hepatitis C virus (HCV) infection is responsible for both hepatic and extra-hepatic disorders (HCV-EHDs); these latter are correlated on one hand clearly with HCV lymphotropism causing immune-system dysregulation as well as with viral oncogenic potential, and on the other hand probably with chronic inflammatory status causing cardio-metabolic complications as well as neurocognitive disturbances. The spectrum of HCV-EHDs ranges from mild or moderate manifestations, such as arthralgia, sicca syndrome, peripheral neuropathy, to severe, life-threatening complications, mainly vasculitis and neoplastic conditions. Given the clinical heterogeneity of HCV-EHDs, HCV-infected individuals are inevitably referred to different specialists according to the presenting/prevalent symptom(s); therefore, the availability of comprehensive diagnostic guidelines is necessary for a patient's whole assessment that is decisive for early diagnosis and correct therapeutic approach of various hepatic and HCV-EHDs, regardless of the specific competencies of different physicians or referral centers. In this respect, a multidisciplinary network of experts, the International Study Group of Extrahepatic Manifestations Related to Hepatitis C Virus Infection (ISG-EHCV), was organized with the intention to formulate diagnostic guidelines for the work-up of possible HCV-EHDs. There was a broad consensus among ISG-EHCV members on the proposed guidelines, which essentially are based on two main levels of patient's assessment. At the referral stage, it is proposed that all patients with HCV infection should be invariably examined by means of first-line diagnostic procedures including virological and hepatic parameter evaluation, as well as the detection of clinical findings that may suggest one or more HCV-EHDs. This preliminary assessment should reveal specific HCV-EHDs, which will be deeper analyzed by means of second-line, targeted investigations. The proposed multidisciplinary expert statement represents the first attempt to draw comprehensive diagnostic guidelines for HCV-infected individuals encompassing the entire spectrum of HCV-related disorders, namely typical hepatic manifestations along with less common, often unpredictable HCV-EHDs. The HCV-EHDs may compromise to a substantial degree the overall disease outcome in a significant number of HCV-infected individuals that renders their timely identification and treatment an imperative. In conclusion, the application of standardized but thorough diagnostic guidelines of HCV-EHDs is advisable at the referral stage as well as during the follow-up period of HCV infected patients. It is envisioned that the proposed strategy will result in improvement of clinical outcomes in such patients., (Copyright © 2016. Published by Elsevier B.V.)

Hepatitis C virus (HCV) infection is associated with tremendous morbidity and mortality due to liver complications. HCV infection is also associated with many extrahepatic manifestations including cardiovascular diseases, glucose metabolism impairment, cryoglobulinemia vasculitis, B cell non-Hodgkin lymphoma and chronic kidney disease (CKD). Many studies have shown a strong association between HCV and CKD, by reporting (i) an increased prevalence of HCV infection in patients on haemodialysis, (ii) an increased incidence of CKD and proteinuria in HCV-infected patients, and (iii) the development of membranoproliferative glomerulonephritis secondary to HCV-induced cryoglobulinemia vasculitis. HCV seropositivity is found to be associated with an increased relative risk for all-cause and cardiovascular mortality in the dialysis population. HCV seropositivity is linked to lower patient and graft survival after kidney transplantation. Such poor HCV-associated prognosis should have encouraged clinicians to treat HCV in CKD patients. However, due to frequent side effects and the poor efficacy of interferon-based treatments, very few HCV dialysis patients have received HCV medications until now. The emergence of new direct acting, interferon-free antiviral treatment, leading to HCV cure in most cases with a satisfactory safety profile, will shortly modify the management of HCV infection in CKD patients. In patients with a glomerular filtration rate (GFR) >30ml/min, the choice of DAA is not restricted. In those with a GFR <30 and >15ml/min, only paritaprevir/ritonavir/ombitasvir/dasabuvir or a grazoprevir plus elbasvir regimen are approved. In patients with end stage renal disease (GFR <15ml/min or dialysis), current data only allows for the use of a grazoprevir plus elbasvir combination. No doubt these data will be modified in the future with the advent of new studies including larger cohorts of HCV patients with renal impairment., (Copyright © 2016 European Association for the Study of the Liver.

Background: Chronic myeloid leukemia (CML) is associated to the BCR-ABL1 oncogene and can successfully be treated with tyrosine kinase inhibitors (TKIs). However, it remains still under investigation which molecular factors may influence CML risk or varying responses to TKIs. The aim of this study was to assess the role of Glutathione-S-transferases (GSTs) genetic polymorphisms in CML susceptibility and TKI clinical outcome., Materials: Deletion polymorphisms in GSTM1 and GSTT1 genes and the single nucleotide polymorphism in GSTP1 c.319A>G (rs1695; p.105Ile>Val) were genotyped by PCR methods in 141 CML treated patients and 141 sex- and age-matched healthy individuals., Results: Individual analysis of each GST gene showed no association with CML risk. A trend toward significance (p=0.07) for a recessive model was found for GSTP1 (OR: 2.04; CI: 0.94-4.4). However, the combined analysis showed that GSTM1-null/GSTP1-GG as well as GSTT1-null/GSTP1-GG were associated with CML development (p=0.03; OR: 3.54 CI: 1.2-14.57; p=0.05; OR: 12.65; CI: 1.17-21.5). The relationship with treatment outcome showed that the presence of GSTM1 gene was significantly linked with an inferior rate of major molecular response (p=0.048) and poor event free-survival (EFS) (p=0.02). Furthermore, a group of patients with GSTP1-GG genotype were significantly associated with reduced EFS comparing to those carrying other GSTP1 genotypes (p=0.049). GSTP1-GG genotypes had short time to treatment failure in a group of patients unresponsive to TKIs comparing to other GSTP1 genotypes (p=0.03)., Conclusions: This study highlights the significance of GSTM1 and GSTP1 polymorphisms on CML susceptibility and response to TKIs in the Argentinean population., (Copyright © 2016 Elsevier Ltd.

The beneficial effects of statin therapy in reducing cardiovascular morbidity and mortality is not merely explained by the lipid-modulating effects. Although adipokines levels have been associated with cardiometabolic disorders, a few studies have explored the effect of statin on resistin and visfatin. We aimed to evaluate the impact of statin therapy on levels of resistin and visfatin through a meta-analysis of published studies. A systematic literature search in Medline and SCOPUS databases was conducted up to January 2015 to identify controlled trials assessing changes in plasma concentrations of visfatin and resistin during treatment with statins. Quantitative data synthesis was performed using a random-effects model, with weighed mean difference (WMD) and 95% confidence interval (CI) as summary statistics. 12 eligible studies with 14 treatment arms were included. Overall, 844 participants were studied. No significant change in plasma resistin concentrations was observed following statin therapy (WMD: -0.11ng/mL, CI: -1.94,1.73, p=0.909). This effect was robust and not affected by statin type, treatment duration and LDL-cholesterol concentrations. With respect to visfatin concentrations, there was a marginally significant reduction following statin therapy (WMD: -2.40ng/mL, CI: -4.79,-0.002, p=0.050). However, this effect size was weak and sensitive to three of the trials included in the analysis. This meta-analysis did not suggest any effect of statin therapy on plasma resistin levels, while a slight reduction in visfatin levels was found. The effect of statins on visfatin levels may represent a novel pleiotropic characteristic of these drugs., (Copyright © 2016 Elsevier Ltd. All rights reserved.)

No study has evaluated the incidence of new cases of thyroid autoimmunity (AT) and dysfunction (TD) in hepatitis C-associated mixed cryoglobulinemia (MC) patients. We aimed to evaluate the incidence of new cases of AT and TD in a wide group of MC patients vs. age- and gender-matched controls from the same geographic area. After exclusion of MC patients with TD at the initial evaluation, the appearance of new cases of TD was evaluated in 112 MC patients and 112 matched controls, with similar iodine intake (median follow-up 67months in MC vs. 78 in controls). A high incidence (P<0.05) of new cases of hypothyroidism, TD, anti-thyroperoxidase antibody (AbTPO) positivity, appearance of a hypoechoic thyroid pattern, and thyroid autoimmunity in MC patients vs. controls was shown. A logistic regression analysis showed that in MC, the appearance of hypothyroidism was related to female gender, a borderline high initial thyroid-stimulating hormone (TSH), AbTPO positivity, a hypoechoic, and small thyroid. In conclusion, we show a high incidence of new cases of AT and TD in MC patients. MC patients at high risk (female gender, a borderline high initial TSH, AbTPO positivity, a hypoechoic, and small thyroid) should have periodically thyroid function follow-up., (Copyright © 2016 Elsevier B.V.

Background: Interstitial lung diseases (ILDs) are a heterogeneous group of disorders characterized by inflammation and/or fibrosis of the lungs, varying from idiopathic interstitial pneumonias to secondary variants, including the ILDs associated to connective tissue diseases (CTDs). In addition, a number of patients are recognized as unclassifiable ILD (U-ILD), because of the inability to reach a definite diagnosis; some of them show autoimmune manifestations not fulfilling the classification criteria of a given CTD. The term interstitial pneumonia with autoimmune features (IPAF) has been recently proposed for this particular ILD subset., Methods: Here, we report our experience resulting from the integrated - pneumology/rheumatology - approach to patients with suspected ILDs or CTDs referred to our university-based Center for the Rare Pulmonary Diseases and Rheumatology Unit, from January 2009 to June 2015, with particular attention to the above-mentioned U-ILD, IPAF, and undifferentiated connective tissue disease (UCTD). The comparative analysis of these clinical variants was carried out; moreover, the observed findings were compared with the results of the updated review of the literature., Results: After the first clinical assessment, the U-ILD were identified in 50 patients; afterwards, on the basis of clinico-serological and radiological findings U-ILD group was subdivided into 2 subgroups, namely U-ILD without any clinical extra-thoracic manifestations and/or immunological alterations (15 pts) and IPAF according to the above-mentioned classification criteria (35 pts). Patients with either IPAF or U-ILD were compared with a series of 52 stable UCTD (disease duration ≥3 years), followed at our Rheumatology Unit. Some important differences were evidenced among the 3 series of U-ILD, IPAF, and UCTD: firstly, female gender was more frequent in patients with UCTD (86%) or IPAF (69%) compared with U-ILD (60%) or idiopathic pulmonary fibrosis (24%; p=0.001). In addition, UCTD patients were younger and showed longer disease duration. More interestingly, both UCTD and IPAF series show a comparable prevalence of various clinical manifestations, with the exception of the interstitial lung involvement detectable in a very small percentage of UCTD patients. Concordantly, the review of the literature evidenced two main subsets of U-ILD, one is characterized by isolated unclassifiable interstitial pneumonia and another one composed by subjects with clinically prevalent lung involvement in the setting of not definite CTD, the recently proposed IPAF., Conclusion: We hypothesize that IPAF and UCTD might represent two clinical variants of the same systemic autoimmune disorders. The marked difference regarding the prevalence of ILD, which is the clinical hallmark of IPAF but very rare in UCTD, may at least in part reflect a selection bias of patients generally referred to different specialist centers, i.e. pneumology or rheumatology, according to the presence/absence of clinically dominant ILD, respectively. Well-integrated, interdisciplinary teams are recommended for the assessment and management of these patients in the clinical practice. Finally, the cooperation between multidisciplinary groups with different experiences may be advisable for a validation study of the proposed nomenclature and classification criteria of these indefinable ILD/CTD variants., (Copyright © 2015 Elsevier B.V.

Background: The treatment of systemic sclerosis (SSc) represents a great clinical challenge because of the complex disease pathogenesis including vascular, fibrotic, and immune T- and B-lymphocyte-mediated alterations. Therefore, SSc should be treated by combined or sequential therapies according to prevalent clinico-pathogenetic phenotypes. Some preliminary data suggest that rituximab (RTX) may downregulate the B-cell over expression and correlated immunological abnormalities., Methods: Here, we describe a series of 10 SSc patients (4M and 6F, mean age 46±13.5SD years, mean disease duration 6.3±2.7SD years; 5 pts had limited and 5 diffuse SSc cutaneous subset) treated with one or more cycles of RTX (4 weekly infusions of 375mg/m(2)). The main indications to RTX were interstitial lung fibrosis, cutaneous, and/or articular manifestations unresponsive to previous therapies; ongoing treatments remained unchanged in all cases. The effects of RTX were evaluated after 6months of the first cycle and at the end of long-term follow-up period (37±21SD months, range 18-72months). An updated review of the world literature was also done., Results: RTX significantly improved the extent of skin sclerosis in patients with diffuse SSc at 6months evaluation (modified Rodnan skin score from 25±4.3 to 17.2±4.6; p=.022). A clinical improvement of other cutaneous manifestations, namely hypermelanosis (7/7), pruritus (6/8), and calcinosis (3/6) was observed. Moreover, arthritis revealed particularly responsive to RTX showing a clear-cut reduction of swollen and tender joints in 7/8 patients; while lung fibrosis detected in 8/10 remained stable in 6/8 and worsened in 2/8 at the end of follow-up. Pro-inflammatory cytokines, namely IL6, IL15, IL17, and IL23, evaluated in 3 patients with diffuse cutaneous SSc, showed a more or less pronounced reduction after the first RTX cycle. These observations are in keeping with the majority of previous studies including 6 single case reports and 10 SSc series (from 5 to 43 pts), which frequently reported the beneficial effects of RTX on some SSc manifestations, particularly cutaneous sclerosis, along with the improvement/stabilization of lung fibrosis. Possible discrepancies among different clinical studies can be related to the etiopathogenetic complexity of SSc and not secondarily to the patients' selection and disease duration at the time of the study., Conclusion: The present study and previous clinical trials suggest a possible therapeutical role of RTX in SSc, along with its good safety profile. The specific activity of RTX on B-cell-driven autoimmunity might explain its beneficial effects on some particular SSc clinical symptoms, namely the improvement of skin and articular involvement, and possibly the attenuation of lung fibrosis., (Copyright © 2015.

Chemokine (C-X-C motif) ligand (CXCL)10 is involved in the pathogenesis of psoriasis. It has been demonstrated that chemokine (C-X-C motif) receptors (CXCR)3 and CXCL10 were detected in keratinocytes and the dermal infiltrate obtained from active psoriatic plaques and that successful treatment of active plaques decreased the expression of CXCL10. Elevated CXCL10 serum levels have been shown in patients with psoriasis, with a type 1 T helper cells immune predominance at the beginning of the disease, while a decline of this chemokine has been evidenced later, in long lasting psoriasis. Circulating CXCL10 is significantly higher in patients with psoriasis in the presence of autoimmune thyroiditis. It has been hypothesized that CXCL10 could be a good marker to monitor the activity or progression of psoriasis. Efforts have been made to modulate or inhibit the CXCR3/CXCL10 axis in psoriasis to modify the course of the disease., (Copyright © 2015. Published by Elsevier Urban & Partner Sp. z o.o.)

Background: Recent evidence has indicated that flavanol consumption may have many health benefits in humans, including improved cognitive activities., Objective: The aim was to evaluate the effect of flavanol consumption on cognitive performance in cognitively intact elderly subjects., Design: This was a double-blind, controlled, parallel-arm study conducted in 90 elderly individuals without clinical evidence of cognitive dysfunction who were randomly assigned to consume daily for 8 wk a drink containing 993 mg [high flavanol (HF)], 520 mg [intermediate flavanol (IF)], or 48 mg [low flavanol (LF)] cocoa flavanols (CFs). Cognitive function was assessed at baseline and after 8 wk by using the Mini-Mental State Examination (MMSE), the Trail Making Test (TMT) A and B, and the Verbal Fluency Test (VFT)., Results: The changes in MMSE score in response to the 3 different treatments were not different. In contrast, there was a positive impact of the intervention on specific aspects of cognitive function. Mean changes (±SEs) in the time required to complete the TMT A and B after consumption of the HF (-8.6 ± 0.4 and -16.5 ± 0.8 s, respectively) and IF (-6.7 ± 0.5 and -14.2 ± 0.5 s, respectively) drinks significantly (P < 0.0001) differed from that after consumption of the LF drinks (-0.8 ± 1.6 and -1.1 ± 0.7 s, respectively). Similarly, VFT scores significantly improved among all treatment groups, but the magnitude of improvement in the VFT score was significantly (P < 0.0001) greater in the HF group (7.7 ± 1.1 words/60 s) than in the IF (3.6 ± 1.2 words/60 s) and LF (1.3 ± 0.5 words/60 s) groups. Significantly different improvements in insulin resistance (P < 0.0001), blood pressure (P < 0.0001), and lipid peroxidation (P = 0.001) were also observed for the HF and IF groups in comparison with the LF group. Changes in insulin resistance explained ∼17% of changes in composite z score (partial r² = 0.1703, P < 0.0001)., Conclusions: This dietary intervention study provides evidence that regular CF consumption can reduce some measures of age-related cognitive dysfunction, possibly through an improvement in insulin sensitivity. These data suggest that the habitual intake of flavanols can support healthy cognitive function with age., (© 2015 American Society for Nutrition.)

Capillaroscopy is a noninvasive imaging technique for the in vivo study of microcirculation. The role of a qualitative evaluation of capillaroscopy in the assessment of Raynaud's phenomenon secondary to scleroderma spectrum disorder, particularly systemic sclerosis (SSc), is well defined. The usefulness of capillaroscopy in the follow-up of SSc patients and the possible prognostic role for the appearance of typical SSc vascular and visceral involvement, namely, digital ulcers, pulmonary arterial hypertension, and mortality, is suggested by many authors but still under debate. In this regard, and for a reliable and repeatable longitudinal evaluation of SSc microangiopathy, a quantitative analysis should be required. In this review, we describe the current classifications proposed to define the SSc microvascular involvement and the scoring methods suggested for a semiquantitative and quantitative analysis of microangiopathy and its correlation with clinical manifestations of disease.

The clinical spectrum and prognosis of systemic sclerosis (SSc) seem to vary among patients' populations recruited during different time periods. In order to verify this possible evolution we investigated the clinico-serological and survival rate in a large Italian SSc series (821 patients; 746 females, 75 males; mean age 53.7±13.9SD years) recruited between 2000 and 2011. The observed findings were compared with previous studies of the world literature.Compared to older Italian SSc series, the present patients' population showed a significantly increased prevalence of limited cutaneous SSc (from 72 to 87.5%; p ≤.0001) and serum anti-centromere antibodies (from 39 to 47,4%; p ≤.001), with a significant reduction of lung (from 81 to 63.7%; p ≤.0001), heart (from 35 to 20.5%; p ≤.0001), and renal involvement (from 10 to 3.8%; p ≤.0001), and skin ulcers (from 54 to 16.5%; p ≤.0001). Cumulative 10th-year survival showed a clear-cut increase (80.7%) compared to our previous series (69.2%). These findings were mirrored by the results of survival studies published during the last five decades, grouped according to the time periods of patients'' recruitment at the referral centers. A clear progression of 10th-year survival rates was detectable, from the 54% median survival of the oldest studies (1935-1974) to 74% and 83.5% of the more recent SSc series, 1976-1999 and after 1999, respectively. In conclusion, the favorable evolution of SSc pathomorphosis and prognosis during the last decades might be related to more diffuse physician/patient awareness of this harmful disease and availability of diagnostic tools, the consequent wider recruitment of patients in the early stages of the disease, as well as to the improved therapeutic strategies., (Copyright © 2014 Elsevier B.V.

(C-X-C motif) ligand (CXCL)10 (CXCL10) belongs to the ELR(-) CXC subfamily chemokine. CXCL10 exerts its function through binding to chemokine (C-X-C motif) receptor 3 (CXCR3), a seven trans-membrane receptor coupled to G proteins. CXCL10 and its receptor, CXCR3, appear to contribute to the pathogenesis of many autoimmune diseases, organ specific (such as type 1 diabetes, autoimmune thyroiditis, Graves' disease and ophthalmopathy), or systemic (such as rheumatoid arthritis, psoriatic arthritis, systemic lupus erythematosus, mixed cryoglobulinemia, Sjögren syndrome, or systemic sclerosis). The secretion of CXCL10 by cluster of differentiation (CD)4+, CD8+, natural killer (NK) and NK-T cells is dependent on interferon (IFN)-γ, which is itself mediated by the interleukin-12 cytokine family. Under the influence of IFN-γ, CXCL10 is secreted by several cell types including endothelial cells, fibroblasts, keratinocytes, thyrocytes, preadipocytes, etc. Determination of high level of CXCL10 in peripheral fluids is therefore a marker of host immune response, especially T helper (Th)1 orientated T-cells. In tissues, recruited Th1 lymphocytes may be responsible for enhanced IFN-γ and tumor necrosis factor-α production, which in turn stimulates CXCL10 secretion from a variety of cells, therefore creating an amplification feedback loop, and perpetuating the autoimmune process. Further studies are needed to investigate interactions between chemokines and cytokines in the pathogenesis of autoimmune diseases and to evaluate whether CXCL10 is a novel therapeutic target in various autoimmune diseases., (© 2013.)

Objective: Increased frequency of few types of cancer in systemic sclerosis (SSc) has been reported in the literature; in particular, breast carcinoma has been proposed as one of the most frequent malignancy in SSc patients, even though data are not univocal. The aim of the present study was to retrospectively evaluate the prevalence of breast cancer in our SSc series, compared with sex-/age-matched general population of the same geographical area, and the possible correlations with SSc features, including X-ray exposure for clinical investigations. A review of the world literature about this topic was also done., Methods: Clinical records of 318 consecutive SSc patients, 31 M and 287 F, age 51.5±14.5 SD years, disease duration 10±6.5 SD years, referred to our Rheumatology Unit between January 2002 and December 2012 were evaluated., Results: Twelve (3.8%) cases of breast cancer were recorded, including 11/287 females (3.8%) and 1/31 (3.2%) male patients. Considering the subgroup of 202 SSc patients resident in the Province of Modena compared with data of the local Tumor Registry, the incidence of breast cancer observed in our SSc series is significantly higher than expected (SIR 2.1; 95% interval of confidence: 1.13-3.90; p<0.01). On the whole, the comparison between SSc patients with cancer and those without did not show any significant differences with regard to SSc clinical features, including the X-ray exposure. Of note is the relatively shorter disease duration at the time of breast cancer detection (median 2.5years, range 1-21; disease duration of mean 10±6.5 SD years in the entire cohort). The review of the literature revealed that the observed incidence of breast cancer in our case series is comparable to the few studies reporting the highest percentages of this malignancy., Conclusions: A significant increase of breast cancer incidence compared to sex-age-matched general population from the same geographic area was observed. Moreover, a close temporal relationship between SSc and breast cancer onset was found, independently from clinical, serological, and instrumental features of SSc. The possible pathogenetic link between this systemic autoimmune disease and complicating breast cancer, as well as the results of previous studies, are discussed., (© 2013 Elsevier B.V.

Several studies have suggested that tea consumption might protect against the development and progression of cardiovascular disease, one of the leading causes of morbidity and mortality worldwide. The endothelium plays a pivotal role in arterial homeostasis. Reduced nitric oxide (NO) bioavailability with endothelial dysfunction is considered the earliest step in the pathogenesis of atherosclerosis. Endothelial dysfunction has been considered an important and independent predictor of future development of cardiovascular risk and events. The association between brachial NO-dependent flow-mediated dilation (FMD) and cardiovascular disease risk has been investigated in several prospective studies, suggesting that FMD is inversely associated with future cardiovascular events. Dietary flavonoids and tea consumption have been described to improve endothelial function and FMD. A proposed mechanism by which dietary flavonoids could affect FMD is that they improve the bioactivity of the endothelium-derived vasodilator NO by enhancing NO synthesis or by decreasing superoxide-mediated NO breakdown. This could be of clinical relevance and may suggest a mechanistic explanation for the reduced risk of cardiovascular events and stroke observed among tea drinkers in the different studies. The purpose of this article is to provide an overview of the relation between tea consumption and cardiovascular disease, with a focus on clinical implications resulting from the beneficial effects of tea consumption on endothelial function.

Objective: Intravesical instillation of BCG (ivBCG) is an effective and safe immunotherapy of bladder carcinoma but it may have, as side effect, a reactive arthritis (ReA). The authors describe 5 cases observed during their own clinical experience along with the updated review of the literature on this topic., Methods: Seventy-three papers were present in the world literature, each reporting almost 1 case for a total of 112 patients. However, the review focused on 61 papers, selected on the basis of reporting suitable for a correct clinical evaluation; thus, a total of 89 patients, including the cases observed in our clinic, were carefully analyzed., Results: Among the 89 patients identified 73 were males and 16 females. Europe is the geographical area with the higher number of reports, namely 80.6% of the papers including 74.2% of the patients. The Mediterranean area accounts for 62.9% of the papers and 59.6% of the cases. The symptoms of ReA appeared after a mean number of instillations of 5.8. Polyarthritis was present in 55.1%, oligoarthritis in 37.0% and monoarthritis in 7.9%. Polyarthritis was symmetric in 51.0% and asymmetric in 49.0% of the cases; oligoarthritis was symmetric in 33.3% and asymmetric in 66.7% of the cases. Overall, an asymmetric distribution of arthritis was present in 59.6%. Knee and ankle were the joints most frequently involved. The antigen HLA B27 was positive in 42.6%. The synovial fluid analysis was defined as flogistic-aseptic in 71.9% of the patients. Arthritis was recovered within 6months in 93.2% of the cases and in 70.5% of the patients within the first two months. NSAIDs and corticosteroids, alone or in conjunction with other drugs, are used in 65.1% and in 40.4% of the cases, respectively. The clinical features of ivBCG ReA are compared with ReA from other triggering agents, from which it differs for some clinical aspects and overlaps for others., Conclusions: Compared with a previous report, this review allows to modify some figures of this topic as a reduced prevalence of polyarthritis (from 70% to 55.1%) and of spinal and sacroiliac involvement; polyarthritis remains the more frequent clinical pattern of ivBCG ReA that, however, is characterized by rather asymmetrical distribution and involvement of the large joints of lower limbs. A definite linkage to HLA B27 is present, although without prognostic value. Moreover, arthritis is aseptic, has a latency time from antigen exposure, and is associated with extra-articular features as commonly observed in ReA from other triggering agents. Arthritis is usually benign and rarely develops into a chronic form. NSAIDs and/or corticosteroids are largely effective. Noteworthy, the overall clinical picture of arthritis triggered by ivBCG emerging from this updated review is comparable to that of ReA from other bacterial agents., (© 2013 Elsevier B.V.

Objective: Systemic sclerosis (SSc) is an immune-mediated disorder characterized by multiple organ fibrotic alterations and diffuse microangiopathy. The SSc can be associated with other connective tissue diseases and less frequently with systemic vasculitides, including cryoglobulinemic vasculitis (CV). The aim of the present study was to investigate the prevalence of CV in a large series of SSc patients., Methods: The presence of serum cryoglobulins was detected in 246 SSc patients (24 M and 222 F, age 61±13.5 SD years, disease duration 9.3±6.7 SD years); the observed clinico-serological findings, in particular the presence of SSc-CV overlapping syndrome, were carefully analyzed and compared with previous data reported in the literature., Results: The presence of circulating cryoglobulins was found in 7/246 (2.8%) of SSc patients; namely, 2 subjects only trace amounts of cryoglobulins, while 5 (2%) showed mixed cryoglobulinemia (type II, IgG-IgMk), low C4, rheumatoid factor seropositivity, and hepatitis C virus infection. Among SSc patients with serum mixed cryoglobulins, 4 (1.6%) developed a clinically overt CV, while the other one was totally asymptomatic with regard to typical vasculitic manifestations. Patients with SSc-CV overlapping syndrome had limited cutaneous SSc with serum anticentromere antibodies, pulmonary hypertension, clinico-serological features of HCV-related CV, and non-healing skin ulcers of the lower limbs. In all cases, the diagnosis of SSc preceded the clinical onset of CV, from 3 to 17years. The treatment with rituximab was useful on skin ulcers of lower limb in 2/3 patients; however, the overall clinical outcome of the four SSc-CV patients was unusually severe: one with very severe skin ulcers complicated by gangrene required bilateral through-the knee amputation, the other three subjects died because of severe heart failure, and in two cases because of untreatable pulmonary hypertension. In the literature, the prevalence of mixed cryoglobulinemia in scleroderma patients is quite rare (range 0.3-2%); while, the association of SSc with clinically overt CV is only anecdotally described, always in the absence of HCV infection., Conclusion: The SSc-CV overlapping syndrome described here is characterized by markedly severe vascular manifestations responsible for very poor prognosis; these peculiar clinical manifestations suggest a synergic activity of typical scleroderma microangiopathy and cryoglobulinemic vasculitis., (Copyright © 2013 Elsevier B.V.

Background and Aims: The association between serum uric acid (SUA) levels and cardiovascular (CV) risk or all-cause death has been repeatedly reported. However, it has not been assessed whether reduction of SUA levels is associated with reduced CV risk. The aim of the current study was to evaluate the relationship between changes of SUA levels and CV events as well as all-cause death., Methods and Results: Randomised trials reporting SUA at baseline and at the end of follow-up and clinical end-points (all-cause death, myocardial infarction (MI), stroke, heart failure (HF) and CV death) were included in the study. Meta-regression analysis was performed to test the relationship between SUA changes and clinical end-points. Eleven trials enrolling 21,373 participants followed up for 2.02 ± 1.76 years and reporting 4533 events were included. In meta-regression analysis, no relationship between SUA changes from baseline to end of follow-up and the composite outcome including CV death, stroke, MI and HF was found (change in Tau(2) (t) = -0.64; p Tau (p) = 0.541). Similarly, no relationship was found between SUA changes and single components of the composite outcome (MI: t = -0.83; p = 0.493; stroke: t = 0.46; p = 0.667; HF: t = 2.44; p = 0.162; CV death: t = -0.54; p = 0.614) and all-cause death (t = -0.72; p = 0.496). Results were confirmed by sensitivity analysis. No heterogeneity among studies or publication bias was detected., Conclusions: Changes in SUA levels observed during pharmacologic treatments do not predict the risk of all-cause death or CV events. As SUA levels are associated with increased CV risk, additional studies with direct xanthine-oxidase inhibitors are requested., (Copyright © 2013 Elsevier B.V. All rights reserved.)

It has been previously shown IFN-α, -β, -γ and TNF-α (synergically with IFNs) dose-dependently induce the release of CXCL9 and CXCL10 chemokines by thyroid follicular cells, suggesting that this process may be related, at least in part, to the appearance of thyroid dysfunction during IFNs therapy. No study has evaluated the effect of IFN-α and -β on CXCL11 chemokine production in thyrocytes. The aims of this study were: (a) to test the effect of IFN-α, -β and -γ on the secretion of the Th1 chemokine CXCL11, in primary cultures of human thyroid follicular cells; (b) to assess the effect of PPAR-γ activation on CXCL11 secretion. In primary cultures of human thyroid follicular cells, CXCL11 was undetectable in the supernatant. IFN-γ, -α and -β dose dependently induced CXCL11 release. TNF-α alone had no effect. The combination of each of the IFNs with TNF-α had a significant synergistic effect on CXCL11 secretion. Treatment of primary cultures of human thyroid follicular cells with rosiglitazone dose dependently inhibited the IFNs stimulated CXCL11 release. Compared with IFN-α and -β, IFN-γ was the most potent stimulus of CXCL11 secretion. In conclusion, we first show that IFN-α, -β and -γ and TNF-α (synergically with IFNs) dose-dependently induce the release of CXCL11 by primary cultures of human thyroid follicular cells, suggesting that this process may be related to the appearance of thyroid dysfunction during IFNs therapy. Furthermore, PPAR-γ activation partially inhibits this process., (Copyright © 2012 Elsevier GmbH. All rights reserved.)

The association between systemic sclerosis (SSc) and cancer was widely described, particularly with breast and lung carcinoma; while, data regarding possible associations between cancer and SSc features are still scarce. We retrospectively evaluated the prevalence of lung cancer in our SSc patient cohort (318 SSc patients, 31 M and 287 F, age 51.5±14.5SD years, disease duration 10.3±6.5SD years) and clinico-serological factors potentially associated to the development of this malignancy. A review of the world literature about this topic was also done. We found that lung cancer complicated 16/318 (5%) SSc patients; namely 11/287 females (4%) and 5/31 males (16.1%). Median age of SSc patients with lung cancer was 54 (range 38-72) years for female patients, and 63 (range 40-73) for males; 13/16 patients died because of the neoplasia. Considering the incidence of lung carcinoma in sex/age-matched general population of the same geographical area, the percentages of lung cancer in our SSc series are about 2.5 and >5 times higher for male and female patients, respectively. The presence of lung cancer significantly correlated with male sex (p=0.011), presence of anti-Scl70 antibodies (p=0.0007), cyclophosphamide therapy (p=0.0001), forced vital capacity (FVC) <75% (p=0.0001), and lung fibrosis (p=0.0127); moreover patients with cancer have a significantly lower age at the diagnosis of SSc (p=0.009) and longer disease duration (p=0.0175). The logistic regression analysis confirmed a significant association with the anti-Scl70 antibodies (OR 6.4, 95%IC 1.7-24.1; p=0.006) and the reduction of FVC (OR 6.7, 95%IC 2.2-20.7; p=0.001) only. Overall, the prevalence of lung cancer in the subset of SSc patients with anti-Scl70 antibodies was 12/105 (11.4%), 9/40 (22.5%) in patients with FVC% reduction, and 7/22 (31.8%) in patients with both. In literature, the median prevalence of lung cancer in SSc series was 2.4% (range 0-4.2%); even if sporadic, associations with lung involvement or antiScl70 autoantibodies were raised, according to our findings. Our study confirmed the higher frequency of lung cancer among SSc patients compared to general population, particularly within patients' subset with serum anti-Scl70 antibodies and lung involvement., (Copyright © 2012 Elsevier B.V.

Objective: To evaluate the risk of serious infections (SIs) in RA patients receiving anti-TNF therapy on the basis of the data included in the GISEA register., Methods: The study involved 2769 adult patients with long-standing RA (mean age 53.2±13.4 years; mean disease duration 9.0±8.3 years) enrolled in the GISEA register, who had been treated for at least 6 months with TNF inhibitors or had discontinued therapy due to SI: 837 (30%) treated with infliximab (IFN), 802 (29%) with adalimumab (ADA), and 1130 (41%) with etanercept (ETN)., Results: 176 patients had experienced at least one of the 226 Sis during the 9 years of treatment with an anti-TNF agent, an overall incidence of 31.8/1000 patient-years (95% CI 25.2-38.3): 23.7/1000 patient-years (95% CI 13.1-34.2) on ADA; 12.8/1000 patient-years (95% CI 6.3-19.4) on ETN and 65.1/1000 patient-years (95% CI 48.4-81.8) on IFN. The risk was higher in the first than in the second year of treatment, but this difference was not statistically significant (p=0.08) (38.9% of the SIs were recorded in the first 12 months of treatment). The risk of SI was significantly different among the three treatment groups (p<0.0001). Multivariate models confirmed that the use of steroids (p<0.046), concomitant DMARD treatment during anti-TNF therapy (p=0.004), advanced age at the start of anti-TNF treatment (p<0.0001), and the use of IFN or ADA rather than ETN (respectively p<0.0001 and p=0.023) were strong and statistically significant predictors of infection., Conclusions: Anti-TNF therapy is associated with a small but significant risk of SI that is associated with the concomitant use of steroids, advanced age at the start of anti-TNF treatment, and the type of anti-TNF agent., (Copyright © 2012 Elsevier B.V.

Objective: There is emerging evidence suggesting that women who develop hypertensive disorders of pregnancy should be considered at risk for cardiovascular disease (CVD). Our objective was to determine whether persistent endothelial activation, which represents the earliest step in atherogenesis, is present after delivery in women with a history of hypertensive pregnancies compared to women with normal pregnancies., Study Design: Two matched case-control studies were conducted. In the first study, endothelial activation was assessed by the measurement of soluble intercellular adhesion molecules, namely, intercellular adhesion molecules-1 (ICAM-1), vascular cellular adhesion molecules-1 (V-CAM-1), E-selectin and P-selectin in 25 women with hypertensive pregnancies and in a matched control group with an uncomplicated pregnancy one month and three months after delivery. In the second study, adhesion molecules were measured in 20 patients with a history of HELLP syndrome several years after pregnancy and in 20 matched controls., Results: Increased levels of soluble adhesion molecules were found in women with hypertensive complications compared to women with uncomplicated pregnancies shortly after delivery. Significant differences were still present, several years after delivery comparing levels of adhesion molecules in women with a history of HELLP syndrome with those found in control patients., Conclusions: Patients with hypertensive pregnancies showed an abnormal activation of the endothelium which persists after pregnancy. This activation was particularly marked in patients experiencing HELLP syndrome. These observations may represent an explanation to the increased risk of CVD later in life in patients experiencing hypertensive pregnancies, especially in women with a history of HELLP syndrome., (Copyright © 2012 International Society for the Study of Hypertension in Pregnancy.

Objective: Mixed cryoglobulinemia syndrome (MCs) is a systemic vasculitis characterized by multiple organ involvement due to the vascular deposition of immune-complexes, mainly the cryoglobulins. B-lymphocyte expansion represents the underlying pathological alteration frequently triggered by hepatitis C virus (HCV) infection. The treatment of MCs syndrome is generally based on antiviral drugs and/or immunosuppressors, among which rituximab, an anti-CD20 monoclonal antibody, has been usefully employed for both cutaneous and visceral MCs organ involvement. This multicenter study retrospectively evaluated the effects of rituximab in a large series of patients with active MCs. The observed results were compared to those emerging from the updated review of the literature on this topic., Methods: The study included 87 patients (male/female 19/68, mean age 62.3±11.4SD years, mean disease duration 9±6.2SD years, HCV infection in 92% of cases) with active cryoglobulinemic vasculitis evaluated before rituximab monotherapy and after 6-month follow-up by means of main clinico-serological parameters. A PubMed search up to May 31, 2011, was done to find published clinical studies, including case reports of MCs treated with rituximab., Results: A significant clinical improvement was observed in a relevant percentage of cases, regardless the presence/absence of associated HCV infection; namely, complete/partial remission of pre-treatment active manifestations was observed in 74% of skin purpuric lesions, up to 87% of non-healing vasculitic leg ulcers, and 44% of the peripheral neuropathy, mainly paresthesias (patient's visual analogical scale from 62±25 to 37±27; p≤.0001). Moreover, cryoglobulinemic nephropathy, observed in 38 patients, significantly improved in 95% of cases (serum creatinine from 1.8±1.1SD to 1.4±0.8SD mg/dl, p≤.0001; 24-hour proteinuria from 2.2±2.1SD to 0.9±1.7SD g/24h, p≤.0001), with complete remission in the 50%. Among 6 patients with complicating non-Hodgkin's B-cell lymphoma a complete or partial remission was observed in 5/6. A complete remission of abdominal vasculitis was also observed in one patient. These beneficial effects were mirrored by the improvement of cryoglobulinemic serological hallmarks, namely cryocrit and low complement C4, in half cases. The safety of rituximab was confirmed by the small number of side effects recorded during the 6-month follow-up. On the whole, the results of the present study are in keeping with those reported in 39 papers present in world literature, including a total of 279 MCs patients., Conclusions: Rituximab may be regarded as useful and safe pathogenetic treatment of cryoglobulinemic vasculitis. The actual role of this drug should be definitely confirmed by randomized controlled trials, as well as its position in the therapeutical strategy, mainly with respect to antiviral treatment in HCV-associated MCs., (Copyright © 2011 Elsevier B.V.

Objective: The objective of this review was to define a core set of recommendations for the treatment of HCV-associated mixed cryoglobulinemia syndrome (MCS) by combining current evidence from clinical trials and expert opinion., Methods: Expert physicians involved in studying and treating patients with MCS formulated statements after discussing the published data. Their attitudes to treatment approaches (particularly those insufficiently supported by published data) were collected before the consensus conference by means of a questionnaire, and were considered when formulating the statements., Results: An attempt at viral eradication using pegylated interferon plus ribavirin should be considered the first-line therapeutic option in patients with mild-moderate HCV-related MCS. Prolonged treatment (up to 72 weeks) may be considered in the case of virological non-responders showing clinical and laboratory improvements. Rituximab (RTX) should be considered in patients with severe vasculitis and/or skin ulcers, peripheral neuropathy or glomerulonephritis. High-dose pulsed glucocorticoid (GC) therapy is useful in severe conditions and, when necessary, can be considered in combination with RTX; on the contrary, the majority of conference participants discouraged the chronic use of low-medium GC doses. Apheresis remains the elective treatment for severe, life-threatening hyper-viscosity syndrome; its use should be limited to patients who do not respond to (or who are ineligible for) other treatments, and emergency situations. Cyclophosphamide can be considered in combination with apheresis, but the data supporting its use are scarce. Despite the limited available data, colchicine is used by many of the conference participants, particularly in patients with mild-moderate MCS refractory to other therapies. Careful monitoring of the side effects of each drug, and its effects on HCV replication and liver function tests is essential. A low-antigen-content diet can be considered as supportive treatment in all symptomatic MCS patients. Although there are no data from controlled trials, controlling pain should always be attempted by tailoring the treatment to individual patients on the basis of the guidelines used in other vasculitides., Conclusion: Although there are few controlled randomised trials of MCS treatment, increasing knowledge of its pathogenesis is opening up new frontiers. The recommendations provided may be useful as provisional guidelines for the management of MCS., (Copyright © 2011. Published by Elsevier B.V.)

Cocoa flavonoids are able to reduce cardiovascular risk by improving endothelial function and decreasing blood pressure (BP). Interest in the biological activities of cocoa is daily increasing. A recent meta-analysis shows flavanol-rich cocoa administration decreases mean systolic (-4.5mm Hg; p<0.001) and diastolic (-2.5mm Hg; p<0.001) BP. A 3-mm Hg systolic BP reduction has been estimated to decrease the risk of cardiovascular and all-cause mortality. This paper summarizes new findings concerning cocoa effects on cardiovascular health focusing on putative mechanisms of action and nutritional and "pharmacological" viewpoints. Cocoa consumption could play a pivotal role in human health., (2010 Elsevier Inc. All rights reserved.)

Objectives: To investigate the validity of previously suggested dimensions underlying the Mini-Mental State Examination (MMSE) and differences in associations of these dimensions with sociodemographic and health characteristics in an older Latin-American community sample with low levels of education., Design: Secondary analysis of baseline data from a population-based cohort study., Setting: Bambuí, Brazil., Participants: Of 1,742 total residents aged 60 years or older, 1,558 (89.4%) participated at this study., Measurements: A standard Brazilian version of the MMSE., Results: A five-factor solution (Concentration, Language/Praxis, Orientation, Attention, and Memory) for the MMSE was generated from Principal Components Analysis, and the five-factor solutions proposed in previous studies of developed nation samples were tested in this sample by Confirmatory Factor Analysis. In the adjusted linear regression models, MMSE factors varied in their correlates: for example, female gender was associated with higher concentration, orientation, and attention but lower Language/Praxis; increased age was inversely associated only with language and attention; and activity of daily living impairment was principally associated with lower Language/Praxis., Conclusion: This study provides support for the cross-sectional equivalence of the MMSE, suggesting that most of the items and underlying constructs remain meaningful after alteration and translation in a low-education sample with lower overall distribution of scores.
