Inflammation is among the basic mechanisms of arterial atherosclerotc diseases and is most likely also involved in the onset of venous thromboembolic disease. Various risk factors for atherosclerosis cause damage to the vascular wall and trigger inflammatory changes, which may lead to the development of atherosclerosis. Therefore, people with advanced atherosclerosis, and particularly those with unstable atherosclerotic plaques as a result of intense inflammatory changes, are found to have elevated levels of inflammatory markers in the blood. The most frequent findings include elevated levels of highly specific C-reactive protein (hs-CRP), which is a non-specific systemic indicator of inflammation, and certain interleukins (interleukin–6, interleukin–8) that are considered to be more specific markers of vascular wall inflammation. Therefore, studies are underway to improve the prognostic value for cardiovascular events by the determination of inflammatory markers in the blood. However, due to the unspecifcity of individual inflammatory markers, different methods of their determination and close relation between marker levels and the established risk factors, these have failed to contribute significantly to the evaluation of the role of inflammation in the occurrence of cardiovascular events. Currently, the determination of hs-CRP as one of the most prominent risk factors is recommended only in persons at high risk for cardiovascular events, in those that do not have classical risk factors and are at risk due to other causes, such as e.g. familial predisposition.Recently, it has also been found that inflammation is implicated in the pathogenesis of venous thrombosis. In the case of a damaged venous wall inflammation occurs as a response to injury, while in idiopathic venous thrombosis without the presence of risk factors the vascular wall inflammation is probably a primary event that is followed by coagulation activation. Namely, there is a close association between inflammation and coagulation. Inflammation stimulates procoagulant activity and inhibits endogenous fibrinolysis, and therefore patients with the history of venous thrombosis present with elevated levels of systemic inflammatory markers, particularly of hs-CRP and interleukin. However, it has not been fully explained yet whether the elevated systemic inflammatory markers are a cause of a consequence of venous thrombosis. Te results of our study show that they are most probably a cause for prothrombotic characteristics of the blood and stimulate the occurrence of venous thrombosis, as patients with a history of venous thrombosis even in their stable period (3–5 years) present with elevated inflammatory markers.The increased systemic inflammatory response in arterial atherosclerotic and venous thromboembolic disease is indicative of a close association between both diseases, which are similar as to their pathogenesis but have different clinical features.The recognition of inflammatory basis of arterial and venous diseases is also important from the therapeutic point of view since until recently, in comparison with anticoagulants, medicines with anti-inflammatory activity were rather neglected. Not only has aspirin long been known for its antithrombocytic and also anti-inflammatory activity, it also appears to be effective in long-term prevention of recurrences and progressions of venous thromboses.

Background: Skin cholesterol (SkC) has been suggested to be an additional risk predictor, so we evaluated the test performance, potential determinants of this marker as well as a potential correlation of SkC with markers of inflammation and the history of cardiovascular events. Patients and methods: SkC, determined by the non-invasive PREVU POC Skin Sterol test, as well as serum lipids, the body fat status, high-sensitive CRP (hs-CRP) and serum amyloid A (SAA) were evaluated in consecutive patients with and without documented atherosclerotic disease. Results: SkC was assessed in 201 patients. The within-day precision (CV) was 3.8%, the day-to-day CV of the right hand was 8.6% and 4.3% for the left hand, respectively. Neither univariate analysis nor multiple regressions identified a significant influence of age, sex, serum lipids, body fat status, smoking or diabetes mellitus on SkC, corresponding results were observed in a further analysis including 174 of these patients concerning hs-CRP and SAA (all p > 0.05). T-test analyses detected no significant differences between patients with and without a history of coronary, peripheral vascular and cerebrovascular events (all p > 0.05). Conclusions: The PREVU POC Skin Sterol test for the assessment of SkC proved an acceptable test performance. SkC is independent from serum lipids, traditional cardiovascular risk factors, two sensitive markers of systemic inflammation as well as the history of cardiovascular events indicating that the perception of this parameter as an established marker of vascular disease is premature.

Abstract Background/Aims  Rheumatological conditions can present with a number of non-specific features like arthralgia, fever, fatigue, weight loss along with raised inflammatory markers and positive antibodies. Due to this, when similar symptoms are referred for input it is very important to consider other ‘mimics’. We report a case of Pigeon fancier’s lung presenting with these symptoms which was referred as likely connective tissue disease. Methods  A 52-year-old lady of South Asian origin was referred by her GP with six month history of 3kg weight loss, arthralgia, fatigue, low grade fever and persistently raised inflammatory markers (ESR ranging from 50-64 mm/hr, CRP 10-14 mg/L, normal BMI). On further questioning there was history of mouth ulcers, non-specific rash, occasional cough but no Raynaud’s or joint swelling. Blood investigations showed weakly positive ANA and RF but negative ENA, DNA, antiCCP , CK, C3,C4. C-ANCA was positive but PR3 negative. CXR was clear and tests for chronic infections including TB were negative. Due to lack of objective CTD signs, plan was to take a careful monitoring approach to see if clinical features evolved. A month later due to worsening cough, a CT chest/abdomen arranged by GP showed ground-glass changes consistent with pneumonitis and hence her rheumatology appointment was expedited to see if there was an autoimmune unifying diagnosis. She was also referred by her GP to the chest clinic in view of CT report and mild shortness of breath. Results  On further review, again there were no objective CTD signs. On direct questioning there was history of travelling before worsening chest symptoms to South Asia. Also around a year before her symptoms started she was given an African grey parrot. Based on this, serology for Avian precipitin was checked which showed strongly positive IgG antibodies to avian antigens (Budgerigar droppings and feathers, Pigeon feathers IgG Abs) confirming the diagnosis of pigeon fanciers lung. She fulfilled the diagnostic criteria and was asked to avoid the trigger. Urgent respiratory input was arranged where diagnosis was agreed with and disease was deemed sub-acute in presentation. Due to PFTs showing low transfer factor of 38%, Prednisolone was started with significant improvement within few days. Review of CT chest only showed inflammatory changes and no established fibrosis predicting excellent prognosis as delay in treatment can cause irreversible pulmonary fibrosis. Conclusion  A number of conditions can mimic rheumatological conditions which usually turn out to be either infectious or malignant in origin. This case highlights the importance of considering other differentials and along with taking a travel history also asking for other possible triggers like pets. In similar scenarios the diagnosis may be ‘cagey’ but as rheumatologists we are expected to answers questions which others can’t. Disclosure  M.F. Kazmi: None.

Abstract Background Despite recent advances in secondary prevention, recurrent cardiovascular events are common after a myocardial infarction (MI). It has been reported that genetic risk scores may predict the risk of recurrent cardiovascular events. Although patient-derived family history is a composite of both genetic and environmental heritability of atherosclerotic cardiovascular disease (ASCVD), it is an easily accessible information compared to genetically based risk models but the association with recurrent events is unknown. Purpose To evaluate whether a register-verified family history of ASCVD is associated with recurrent cardiovascular events (rASCVD) in patients after a first-time MI. Methods We included patients with a first-time MI during 2005 – 2014, registered in the SWEDEHEART SEPHIA registry and without prior ASCVD. Follow-up was available until Dec 31st, 2018. Data on relatives, diagnoses and prescriptions were extracted from national registers. A family history of ASCVD was defined as a register-verified hospitalisation due to MI, angina with coronary revascularization procedures, stroke or cardiovascular death in any parent. Early history was defined as such an event before the age of 55 years in fathers and 65 years in mothers. The association between family history and a composite outcome including recurrent MI, angina requiring acute revascularization, ischaemic stroke and cardiovascular death during follow-up was studied with Cox proportional hazard regression with time from SEPHIA registry completion as underlying time-scale, adjusted for age with splines, gender and year of SEPHIA registry. Regression models were then further adjusted for hypertension, diabetes, smoking and for a subset of patients, LDL-cholesterol (LDL_C) at time of first event. Results Of 25,615 patients, 2.5% and 32.1% had an early and ever-occurring family history of ASCVD, respectively. Patients with early family history were significantly younger than other patients and were more likely to be current smokers and have a higher LDL-C (Median (IQR) 3.5 (1.1) vs 3.3 (1.1) mmol/L). In total, 3,971 (15.5%) patients experienced the outcome. Early family history of ASCVD was significantly associated with rASCVD (Hazard ratio (HR) 1.52, 95% confidence interval (CI) 1.23–1.87), and the effect was sustained when adjusted for cardiovascular risk factors (HR 1.48, 95% CI 1.20–1.83) and LDL-C (HR 1.35, 95% CI 1.04–1.74). Ever-occurring family history was weakly associated with ASCVD (HR 1.09, 95% CI 1.02 – 1.17) and the association remained unchanged with adjustments for risk factors. Conclusions Early family history of cardiovascular disease is a potent risk factor for recurrent cardiovascular events in a secondary prevention setting, independent of traditional risk factors including LDL-C. This is a novel finding and these patients may potentially benefit from intensified secondary preventive measures after a first-time MI.

Context: Age-related declines in testosterone and IGF-I are associated with deposition of visceral fat, a component of the metabolic syndrome (MES). Objective: Testosterone and IGF-I may interact with familial disposition to diabetes mellitus to increase the association with MES. Design: We conducted a cross-sectional cohort study. Setting: The study was conducted in a university teaching hospital. Subjects: Study subjects included 179 middle-aged men with a family history of diabetes (FH) (aged 39.1 ± 8.1 yr) and 128 men without FH (aged 43.8 ± 8.5 yr). Main Outcome Measures: Clinical characteristics, frequency of MES using the World Health Organization criteria with Asian definitions of obesity (body mass index ≥ 25 kg/m2), and serum levels of total testosterone, IGF-I, and high-sensitive C-reactive protein (hs-CRP) were measured. Results: Men with FH had higher frequency of MES than those without FH [39.1 vs. 23.4% (P = 0.004)]. On multivariate analysis, smoking (former and current smokers), low total testosterone, and IGF-I but elevated hs-CRP levels explained 35% of the MES variance in men with FH. The frequency of MES increased with declining tertiles of total testosterone and IGF-I but increasing tertiles of hs-CRP. After adjustment for age and smoking history, subjects with all three risk factors had a 13-fold increase in risk association with MES compared with those without hormonal and inflammatory risk factors. These risk associations were not found in men without FH in whom only smoking (ex and current) and low total testosterone level were independent predictors for MES, which explained 14% of the variance. Conclusions: Clustering of FH, hormonal abnormalities, and high hs-CRP is associated with MES in Chinese middle-aged men.

Abstract Abstract 2849 Background We have previously reported on the natural history of polycythemia vera (PV), focusing primarily on overall and leukemia-free survival (ASH Annual Meeting Abstracts. 2011;118(21):277-). In the current study, we present, on behalf of the International Working Group for Myeloproliferative neoplasms Resarch and Treatment (IWG-MRT), our analysis regarding risk factors for thrombosis. Methods Under the auspices of IWG-MRT, seven international centers of excellence for myeloproliferative neoplasms participated in the current study. The two principle investigators (AT and TB) reviewed all the cases and selected 1,545 patients who met the 2008 WHO criteria for PV, were age 18 years or older, diagnosed after 1970, and whose submitted data included diagnostically essential information. Results I: Presenting Features Median age was 61 years (range, 18–95; 51% females). Arterial and venous thrombosis history before or at diagnosis was documented in 246 (16%) patients and 114 (7.4%) patients, respectively. Major hemorrhage hemorrhage before or at diagnosis was documented in 17 (4.5%) patients. Other features at diagnosis included pruritus (36%), microvascular disturbances (28.5%), palpable splenomegaly (36%), abnormal karyotype (12%), leukoerythroblastosis (6%), increased LDH (50%), thrombocytosis (53%), extreme thrombocytosis (platelets >1 million mm3; 4%) leukocytosis (49%), JAK2 V617F (95%), other JAK2 mutations (3%), subnormal serum erythropoietin (Epo) level (81%), and endogenous erythroid colonies (EEC; 73%). History of hypertension (46%), hyperlipidemia (18.3%), diabetes (8.4%), and tobacco use (16%) was also obtained. Results II: Clinical Course To date, 347 (23%) deaths, 50 (3%) leukemic progressions, and 138 (9%) fibrotic transformations have been recorded. Overall, cytoreductive treatment was not used in 416 (27%) patients and the remaining were exposed to different agents based on physician discretion. Post-diagnosis arterial or venous thrombosis occurred in 184 (12%) and 137 (9%) patients, respectively. Results III: Risk Factors for thrombosis Arterial and venous thrombosis-free survival, from time of diagnosis, were separately analyzed using the occurrence of thrombosis as the endpoint (uncensored variable) and last follow-up or death before thrombosis as the censored variable. In univariate analysis, the following were significantly associated with post-diagnosis arterial thrombosis: advanced age, leukocyte count, presence of a leukoerythroblastic smear (LES), history of hypertension and history of arterial thrombosis before or at diagnosis; multivariable analysis using all these five parameters identified arterial thrombosis history (RR 2.5, 95% CI 1.6–4.0; p<0.0001), LES (RR 2.3, 95% CI 1.3–4.2; p=0.005) and history of hypertension (RR 1.6, 95% CI 1.1–2.4; p=0.02) as independent predictors of post-diagnosis arterial thrombosis. Only two parameters predicted post-diagnosis venous thrombosis, in univariate analysis, and both remained significant during multivariable analysis: abnormal karyotype (RR 3.1, 95% CI 1.7–5.4; p=0.0001) and history of venous thrombosis (RR 2.4, 95% CI 1.2–4.9). Of note, the type of JAK2 mutation or presence of either subnormal Epo or EEC did not influence either arterial or venous thrombosis. Results IV: Risk Stratification for arterial and venous thrombosis The figures below illustrated arterial or venous thrombosis-free survival of patients stratified by the absence of all risk factors or presence of one or ≥2 risk factors. For arterial thrombosis, the presence of ≥2 risk factors clearly delineated a high risk group (RR 3.1, 95% CI 1.9–5.0) whereas the presence of one (RR 2.4, 95% CI 1.4–4.2) or two risk factors (RR 10.1, 95% CI 3.6–28.2) for venous thrombosis delineated an intermediate and high risk group, respectively. Conclusions: History of arterial thrombosis and venous thrombosis are key risk factors, respectively, for recurrent arterial and venous thrombosis in PV. In addition, abnormal karyotype is a strong independent risk factor for venous thrombosis and the presence of leukoerythroblastosis and hypertension, for arterial thrombosis. This information allows for a simple and practical risk stratification and raises interesting pathogenetic implications that require further clarification.

Background: Acute lower respiratory infection (ALRI) is one of the main causes of morbidity and mortality in children under five years of age, and the respiratory syncytial virus (RSV) remains its leading etiological factor. Although RSV infections occur in all age groups, the most severe course is observed among children. The clinical manifestations include both mild upper respiratory infections and severe infections of the lower tract, such as bronchiolitis and pneumonia that can lead to hospitalization and severe complications, including respiratory failure. Objectives: The study aimed to evaluate the manifestations of RSV infection in hospitalized children younger than 18 months of age and predictors of disease severity, as well as their comparison with the same age group hospitalized due to ALRI of different etiology. Methods: A retrospective analysis was performed on medical records of 448 children hospitalized due to ALRI. The analysis was performed on the total study group and subgroups of children with positive and negative results of the nasal swab for RSV detection. In each group, clinical data, laboratory test results, and imaging results were analyzed. Results: The most common manifestation was pneumonia (n = 82; 63.08%). Otitis media was observed mainly in children under six months of age with lowered inflammatory markers (P < 0.05), conjunctivitis in those with a positive family history of allergies (P < 0.05), and pneumonia in children under six months of age, with lower blood oxygen saturation and inflammatory markers, features of acidosis, and fever-free course (P < 0.05). Respiratory failure affected 13 children (10%). However, no predictors of this complication were noted. Conclusions: As pneumonia was the most common manifestation in children with both RSV-positive and RSV-negative ALRI, it seems advisable to perform the imaging of the lungs on admission and carefully monitor the child’s condition during hospitalization. In both groups, special attention should be paid to the youngest children with low inflammatory markers on hospital admission, increased clinical symptoms, and family history of allergies. Nevertheless, widely known risk factors of RSV infection itself do not reflect the risk of developing pneumonia or respiratory failure in its course.

Abstract Background: Thrombosis is the main cause of morbidity and mortality in pts with Polycythemia Vera (PV). Current risk stratification is based on 2 variables: age &gt;60y and history of thrombosis. Additional thrombotic risk factors in PV are generic cardiovascular risk factors and leukocytosis. JAK2V617F (JAK2VF) variant allele frequency (VAF) at diagnosis is highly heterogeneous. A VAF&gt;75% was associated with higher rate of all thrombosis after diagnosis (Vannucchi AM et al, Leukemia 2007), and a VAF ≥ 60% correlated with increased rate of venous thrombosis (VT) in high-risk pts (Guglielmelli P et al, ASH 2018); however, predictive role of JAK2VF VAF is still debated. Aim: To evaluate the impact of JAK2VF VAF on rate of arterial and venous thrombosis in PV pts. Patients and methods: A cohort of 576 strictly 2016 WHO-defined PV pts followed at Univ. of Florence (1981-2020) were included. All pts were annotated for JAK2VF VAF, determined &lt;3 years from diagnosis, and thrombosis at diagnosis and follow-up (FU). Arterial thromboses (AT) included stroke, transient ischemic attacks, retinal artery occlusion, coronary artery disease, and peripheral arterial disease; VT included cerebral venous thrombosis, deep vein thrombosis, pulmonary embolism. Splanchnic vein thromboses (SVT) were excluded. Only first occurring event was considered. Cox proportional hazard regression model was used for univariate and multivariable analysis. Kaplan-Meier (KM) analysis was used for time-to-event assessment, compared by log-rank test. Results: Median age was 61.4 y (range, 16.2-91.8), 58.2% were male; 62% were high-risk based on current classification. Median JAK2VF VAF was 41.5% (range, 0.3-100). A total of 76 (13.2%) pts had an AT event before/at PV diagnosis and 49 (8.5%) pts had an AT during FU. As regards VT, 64 (11.1%) and 39 (6.8%) pts had a VT before/at or after PV diagnosis, respectively. We found that JAK2 VAF as a continue variable was correlated with the risk of VT in FU (p=0.003) but not with AT (p=0.8). ROC analysis to determine the best cut-off level for JAK2 VAF predicting VT had an AUC of 0.72 and a best cut-off value of VAF=50%. VT at FU were significantly enriched in pts with VAF &gt;50%: 14.5% versus 2.4%, p=&lt;0.0001. VT -free survival (VT-FS) by KM was significantly shorter in the presence of a JAK2 VAF &gt;50% (HR 4, CI 1.9-8.6, p&lt;0.0001) (Figure 1A), whereas no difference was found for AT (HR 0.9). In addition to JAK2VF VAF&gt;50%, univariate analysis for VT-FS identified history of VT (HR 2.9; CI 1.4-6.1, p=0.006), leukocytosis ≥11x10 9/L (HR 1.9; CI 1.1-3.4, p=0.02) and palpable splenomegaly (HR 1.9, CI 1-3.6; p=0.04) as risk factors. Multivariable analysis confirmed VAF&gt;50% (HR 3.8, CI 1.8-8.1, p=0.0006) and previous VT (HR 2.4, CI 1.1-5.1; p=0.02) as independent risk factors for future VT. In contrast, univariate analysis for AT-free survival (AT-FS) identified history of AT (HR 2.5; CI 1.3-4.9, p=0.007), diabetes (HR 3.3; CI 1.6-6.5, p=0.0007), hyperlipidemia (HR 3.1; CI 1.7-5.6, p=0.0003) and hypertension (HR 2, CI 1.1-3.8; p=0.03) as predictors of future AT; age &gt;60y showed only a trend (p=0.08). Multivariable analysis for AT-FS identified diabetes (HR 2.4, CI 1.2-5; p=0.02), hyperlipidemia (HR 2.3; CI 1.2-4.3, p=0.01) and previous AT (HR 2.1, CI 1-4.2; p=0.04) as independent predictors of future AT. Validation: Our findings were validated in an independent cohort of 315 2016-WHO defined PV pts from Policlinico Gemelli, Catholic Univ., Rome. After exclusion of 26 pts with SVT, analysis was conducted on 289 pts, 38 of them with thrombosis as heralding event (21 AT and 17 VT). Multivariable analysis confirmed JAK2VF VAF &gt;50% (HR 2.3, CI 1.03-5.0, p=0.04) and previous VT (HR 4.5, CI 2.0-10.1; p=0.0003) as independent risk factors for future VT. In pts with VAF &gt;50%, the rate of VT at FU was 19.9% vs 7.7%, P=0.005. KM curve showed that VT-FS was significantly shorter in pts with a JAK2VF VAF &gt;50% (HR 2.2, CI 1.2-4.2; p=0.01) (Figure 1B). Of note, impact of JAK2 VAF&gt;50% on VT at FU was statistically significant particularly in conventionally low-risk pts, accounting for an HR of 9.4 (CI 1.2-72) and HR 3.6 (CI 1.3-10) in Florence and Rome cohorts, respectively. Conclusions: These data support JAK2VF VAF as a strong independent predictor for future venous thrombosis in PV, in association with history of prior venous events, reinforcing that AT and VT are associated with unique risk factors in pts with PV.

Background: The Mediterranean diet is rich in lycopene and has been reported to reduce cardiovascular events. The mechanism of prevention of cardiovascular events has not been clearly established. Our aim was to study the effects of a tomatoes-rich diet on markers of vascular inflammation. Methods: Plasma concentrations of E-selectin, intercellular adhesion molecule 1 (ICAM-1), and high sensitivity C-reactive protein (hs-CRP) were determined by ELISA in 103 apparently healthy volunteers. Volunteers were randomly assigned to two groups: 50 participants ate 300 g tomatoes daily for 1 month, and 53 participants ate their usual diet with tomatoes prohibited during that period. Markers of inflammation were measured before enrollment and 1 month after their assigned diet. Results: The two diet groups had similar baseline clinical characteristics and similar baseline levels of inflammatory markers. After 30 days of assigned diet concentrations of hs-CRP, E-selectin and ICAM-1 were unchanged compared with baseline in the tomato-rich diet. However, ICAM-1 concentraion was increased in the regular diet group from 247.55±55ng/ml to 264.71±60.42ng/ml (P=0.01). Conclusions: The mechanisms of benefit of the tomato-rich diet are not directly related to inhibition of markers of vascular inflammation.

Abstract Background Accumulating evidence has shown the association between DNA methylation and hydroxymethylation and the development of atherosclerosis. However, little is known about the diagnostic value of DNA methylation and hydroxymethylation for coronary atherosclerosis. Carotid plaque has a significant correlation with coronary atherosclerosis, which is a common marker for coronary atherosclerosis. Purpose The major aim of the present study is to determine whether DNA methylation and hydroxymethylation combined with carotid plaques can be useful to the diagnosis of coronary atherosclerosis. Methods 113 patients undergoing carotid ultrasound were enrolled into the study and measured the levels of 5-methylcytosine (5-mC) and 5-hydroxymethylcytosine (5-hmC). Crouse score and Gensini score were used to evaluate the severity of carotid and coronary atherosclerosis, respectively. Results With the increasing of severity of carotid plaque and Crouse score, a stepwise upward trend was observed in 5-mC and 5-hmC levels, which were significantly correlated with the risk factors such as FPG and HbA1c levels, Crouse score and Gensini score. Crouse score and 5-hmC, not 5-mC, were the risk factors for coronary atherosclerosis after adjustment for the risk factors. Receiver operating characteristic (ROC) analysis for comparing their diagnostic value for coronary atherosclerosis indicated that 5-hmC combined with Crouse score was the diagnostic biomarker for coronary atherosclerosis, with the highest areas under the curve (AUC), valuable sensitivity and specificity.
