The interaction of persistent antiphospholipid antibodies positivity and cigarette smoking is associated with an increased risk of cardiovascular events: Cross-sectional and longitudinal analysis. Int J Cardiol 2023; 374:108-114. [PMID: 36496037 DOI: 10.1016/j.ijcard.2022.12.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/29/2022] [Revised: 11/15/2022] [Accepted: 12/02/2022] [Indexed: 12/13/2022]
Abstract
BACKGROUND The antiphospholipid antibody (aPL)-positivity was suggested as a nontraditional risk of coronary artery disease (CAD) and it was associated with cigarette smoking. The co-occurrence of them was usually reported in individuals with cardiovascular diseases. This study was to demonstrate their interaction on the increasing risk of cardiovascular events. METHODS AND RESULTS A total of 826 consecutive male individuals who underwent coronary angiography (CAG) /percutaneous coronary intervention (PCI) were prospectively followed and classified into three groups based on different smoking statuses. The current smoking subjects had the highest occurrence of aPL-positivity, including aCL IgM (20.1%) and aβ2GP1 IgM (15.5%). IgM isotype positivity was an independent risk factor of CAD in the multivariate model, OR: 2.70 (1.52-4.80) for aCL IgM and OR:2.50 (1.35-4.63) for aβ2GP1 IgM.The interaction of current smoking and IgM isotype positivity was significantly associated with increased risk of CAD, OR: 8.75(4.59-16.66) for aCL IgM and OR: 8.78(4.28-17.98) for aβ2GP1 IgM. During about 3 years of follow-up, the smoking patients carrying persistent aPL positivity had the highest cumulative incidence of recurrent myocardial infarction and in-stent restenosis after CAD. CONCLUSION The interaction of current smoking and IgM isotype positivity was significantly associated with the increased risk of CAD, including positive aCL IgM and aβ2GP1 IgM. Cigarette smoking elevated the risk of subsequent cardiovascular events in the presence of IgM isotype positivity, including recurrent myocardial infarction and in-stent restenosis.

Abstract
PURPOSE OF REVIEW The purpose of our review was to evaluate current standards in clinical practice in determining overall cardiac risk in female patients with chronic rheumatologic diseases. We hoped to not only summarize known cardiac manifestations of various chronic rheumatologic diseases but also determine the effectiveness of new risk scores in determining cardiac risk in this patient population. RECENT FINDINGS Chronic rheumatologic diseases have been associated with various cardiac manifestations for some time, with initial studies involving risk of coronary artery disease (CAD) in rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). However, recent studies have shown numerous other cardiac manifestations associated with these and other chronic rheumatologic diseases. Risk scores have been used for several decades to help determine overall cardiac risk in the general population, but these risk scores have notoriously underestimated the risk of cardiac disease in woman and in patients with chronic rheumatologic diseases. These diseases, often with a female predominance, can impact long-term mortality and have devastating consequences if not monitored and treated appropriately. Thus, new risk scores have been developed over the last several years to help improve detection and awareness of cardiac disease in these patients. Novel modified risk scores have found some success at improving the detection of cardiac disease in patients with chronic rheumatologic diseases. Further studies looking at these risk scores need to determine the accuracy of these scores and where they fall short. With the advent of advanced imaging technologies, future risk scores may involve certain imaging-based markers to help guide accurate risk determination.

Abstract
INTRODUCTION Antiphospholipid antibodies (aPL) affect atherogenesis and may cause thromboembolism in systemic lupus erythematosus (SLE) and coronary artery disease (CAD). Intensive treatment with statins may reduce inflammation and decrease the number of thrombotic events. That may explain the beneficial effect of statin therapy in SLE and CAD. This study was established to investigate the influence of statin treatment on aPL antibody levels and selected endothelial dysfunction markers in CAD and SLE patients. MATERIAL AND METHODS Fifty-eight patients - 40 after coronary revascularization (age 38.9 (27-46), 35 males) and 18 with clinically stable SLE (age 38.8 (18-62), 1 male) - were enrolled in the study. In both groups intensive atorvastatin treatment was administered. At baseline and after 1 year of follow-up serology tests were performed: anticardiolipin antibodies (aCL), anti-β2 glycoprotein I (aβ2GPI), lupus anticoagulant (LA), C-reactive protein (CRP), soluble form of intracellular adhesion molecule-1 (sICAM-1), vWF:Ag. RESULTS Coronary artery disease patients in 1 year follow-up revealed a decrease of aβ2GPI IgG and CRP. There was a significant increase in aCL IgG, sICAM-1 and vWF:Ag. In SLE patients aPL levels showed no significant reduction after treatment. CONCLUSIONS In clinically stable patients IgM and IgG class aβ2GPI levels are higher in CAD than in SLE, whereas IgG class aCL levels are lower. Statin treatment decreases the CRP level in both SLE and CAD patients, while decreasing the aβ2GPI IgG level only in CAD patients.

Abstract
Thrombotic Antiphospholipid Syndrome (APS) is a condition affecting young individuals in whom a thromboembolic event occurs in the presence of circulating antiphospholipid antibodies (aPL). An extensive body of literature has covered the most common clinical presentation of the syndrome, venous thromboembolism. Arterial thrombosis in APS, a lesser clinical expression, is less studied. This review will concentrate on the body of literature concerning pathogenesis, clinical presentation and management of arterial thrombosis in APS.

Abstract
Antiphospholipid syndrome (APS) is a multisystem autoimmune disease most commonly associated with recurrent arterial and venous thromboembolism and recurrent fetal loss. Other possible antiphospholipid antibody (aPL)-related clinical manifestations include cardiac involvement. The heart can be involved through immune mediated and /or thrombotic mechanisms. Mortality due to cardiovascular problems is elevated in APS. However, the cardiovascular risk in patients with primary APS (PAPS) compared with lupus-related APS is yet to be established. Cardiac symptoms of APS include valve abnormalities (thickening and vegetations), coronary artery disease (CAD), myocardial dysfunction, pulmonary hypertension, and intracardiac thrombi. Heart valve lesions are the most common cardiac manifestation, observed in approximately one third of PAPS patients and usually do not cause hemodynamic significance. Deposits of immunoglobulins including anticardiolipin (aCL), and of complement components, are commonly observed in affected heart valves from these patients. This suggests that an inflammatory process is initiated by aPL deposition, eventually resulting in the formation of valvular lesion. aPL may have a direct role in the atherosclerotic process via induction of endothelial activation. Multiple traditional and autoimmune-inflammatory risk factors are involved in triggering an expedited atherosclerotic arterial disease evident in APS. It is imperative to increase the efforts in early diagnosis, control of risk factors and close follow-up, in the attempt to minimize cardiovascular risk in APS. Clinicians should bear in mind that a multidisciplinary therapeutic approach is of paramount importance in these patients. This article reviews the cardiac detriments of APS, including treatment recommendations for each cardiac complication.

Abstract
Women have a higher prevalence of several inflammatory rheumatologic conditions. These include systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), and systemic sclerosis (SSc) to name a few. These conditions are all associated with higher rates of cardiovascular (CV) morbidity and mortality, which is driven primarily by atherosclerotic heart disease. Traditional risk factors are important considerations in the assessment of CV risk in the rheumatologic patient; however, these factors do not appear to impart a similar weight of risk in women with inflammatory autoimmune rheumatologic conditions. In addition, even when controlling for traditional risk factors, patients with RA or SLE continue to have a higher risk of CV events, which has been linked to the burden of systemic inflammation. Currently, the CV risk scoring systems available for the general population underestimate the burden of the problem in these complex patients. The increased CV risk in patients with rheumatologic diseases has been reported in the literature for years but remains underrecognized by internists and cardiologists. Although these conditions themselves are relatively rare, the further study of inflammation and its treatment in CV disease will be beneficial to the general population.

Abstract
The non-traditional cardiovascular (CV) risk factors that appear to be of most clinical interest include: apolipoprotein A (ApoA), apolipoprotein B (ApoB), high-sensitivity C-Reactive protein (hsCRP), homocysteine, interleukin 1 (IL1), lipoprotein (a) [Lp(a)], the density of low-density lipoprotein (LDL) particles, the LDL particle number, tissue/tumor necrosis factor-α (TNF-α) and uric acid. These non-traditional risk factors may be of value in adding further confirmation and attention to suspected significant CV risk. They can also provide a better understanding of current concepts of atherogenesis (e.g. various potential mechanisms associated with inflammation) as an etiology and in guiding current plus future therapies. In the mid-20th century, atherosclerosis and CV disease were considered mechanistic occurrences with essentially no attention to possible metabolic and molecular etiologies. Therefore, the only treatments then centered around mainly surgical procedures to try to improve blood flow, first with peripheral arterial disease (PAD) and later coronary artery disease (CAD). Now, failure to treat CV risk factors, especially where there is good evidence-based medicine, as in the case of statins for high CV risk patients, is considered medical negligence. Nevertheless, many problems remain to be solved regarding atherosclerosis prevention and treatment.

Abstract
OBJECTIVES A history of recurrent miscarriage is associated with future cardiovascular disease. The aim of this study was to determine novel cardiovascular biomarkers in women with a history of recurrent miscarriage as this might lead to a better understanding of the association. STUDY DESIGN Women who visited the recurrent miscarriage clinic at Leiden University Medical Centre (between 2000 and 2010), and had three consecutive miscarriages ≤30 years were invited to participate in this follow-up study (between 2012 and 2014). The reference group consisted of women with at least one uncomplicated pregnancy and a history of no miscarriage, matched on zip code, age, and date of pregnancy. MAIN OUTCOME MEASURES Cardiovascular biomarkers were determined, classified into; inflammation (HsCRP, lipoprotein-associated phospholipase A2), thrombosis (homocysteine, folate, anti-cardiolipin antibodies and anti-ß-2-glycoprotein antibodies), lipid metabolism (lipoprotein(a)), renal function (creatinine, microalbuminuria), myocardial damage (N-terminal pro-brain natriuretic peptide, high sensitive TroponineT) and multiple mechanisms (albumin, vitamin D). RESULTS In both groups, 36 women were included. Women with recurrent miscarriage had a significantly higher median HsCRP (1.49 mg/L) compared to women with no miscarriage (1.01 mg/L, p = 0.03) and a significantly lower mean albumin (46.0 vs 47.6g/L, p = 0.004) and vitamin D (55.6 vs 75.4nmol/L, p = 0.007), respectively. Differences remained after adjustments for classic cardiovascular risk factors (BMI, smoking, diabetes mellitus, and hypertension). CONCLUSIONS Our findings suggest a proinflammatory state in women with a history of recurrent miscarriage, which suggests a less optimal health, compared to women with no miscarriage. More research (observational and intervention) is warranted to investigate the association with vitamin D.

Abstract
IgA anti-beta2-glycoprotein I (IgA-aB2GPI) antibodies are currently not included as a laboratory criterion of antiphospholipid syndrome (APS). In the 13th International Congress on Antiphospholipid Antibodies, Galveston, TX, (USA) in 2010, these antibodies were accepted as an APS laboratory criterion in patients who had clinical manifestations of APS but were negative for "consensus" antiphospholipid antibodies (aPL) (IgG and IgM isotypes). Consequently, individuals with thrombotic events who are negative for consensus aPL may be undiagnosed for APS. The most recent publications have confirmed that IgA-aB2GPI antibodies are a risk factor for thrombotic events. In this viewpoint, we propose that IgA-aB2GPI antibodies should be included as an APS consensus criterion and that we have to help Cinderella become a princess.

Abstract
BACKGROUND The antiphospholipid syndrome (APS) is defined by simultaneous presence of vascular clinical events and antiphospholipid antibodies (aPL). The aPL considered as diagnostics are lupus anticoagulant and antibodies anticardiolipin (aCL) and anti-ß2 glycoprotein-I (aB2GP1). During recent years, IgA aB2GP1 antibodies have been associated with thrombotic events both in patients positive, and mainly negative for other aPL, however its value as a pro-thrombotic risk-factor in asymptomatic patients has not been well defined. OBJECTIVE To test the role of IgA anti B2GP1 as a risk factor for the development of APS-events (thrombosis or pregnancy morbidity) in asymptomatic population with a 5-year follow-up. METHODS 244 patients isolated positive for anti-beta2-glycoprotein I IgA (Group-1 study) and 221 negative patients (Group-2 control) were studied. All the patients were negative for IgG and IgM aCL. RESULTS During the follow-up, 45 patients (9.7%) had APS-events, 38 positive for IgA-aB2GP1 and 7 negative (15.6% vs 3.2%, p<0.001). The incidence rate of APS-events was 3.1% per year in IgA-aB2GP1 positive patients and 0.6% per year in the control group. Arterial thrombosis were the most frequent APS-events (N = 25, 55%) and were mainly observed in Group-1 patients (21 vs 4, p = 0.001). Multivariate analysis were shown as independent risk-factors for the development of APS-events, age, sex (men) and presence of IgA-aB2GP1 (odds ratio 5.25, 95% CI 2.24 to 12.32). CONCLUSION The presence of IgA-aB2GP1 in people with no history of APS-events is the main independent risk factor for the development of these types of events, mainly arterial thrombosis.

Abstract
Introduction Many studies have demonstrated elevated circulating levels of high-mobility group box 1 (HMGB1) and decreased circulating levels of soluble receptor for advanced glycation end products (sRAGE) in patients with autoimmune diseases. In the present study, we investigated plasma levels of both HMGB1 and sRAGE in primary antiphospholipid syndrome (pAPS) patients. Methods We prospectively recruited 11 pAPS patients, 17 antiphospholipid antibody (APA)-positive SLE patients without APS manifestations (APA+SLE) and 12 SLE patients with secondary APS (APS+SLE). We also recruited 10 healthy controls (HCs). Plasma levels of HMGB1 and sRAGE were determined using sandwich ELISA kits. In addition, plasma levels of HMGB1 were also determined using Western blot in 6 pAPS patients and 6 HCs. Results There was no significant difference in plasma levels of HMGB1 measured by ELISA among subgroups of the enrolled subjects. In addition, there was no significant difference in plasma levels of HMGB1 measured by Western blot between pAPS patients and HCs. On the other hand, we observed a trend toward lower plasma levels of sRAGE in APA+SLE or APS+SLE patients when compared with HCs. However, there was no significant difference in plasma levels of sRAGE between pAPS patients and HCs, or between APA+SLE patients and APS+SLE patients. Conclusion There was no significant difference in plasma levels of sRAGE or HMGB1 between pAPS patients and HCs. Plasma levels of sRAGE/HMGB1 could not be utilized to differentiate between APA+SLE and APS+SLE patients.

Abstract
BACKGROUND Avidity of antiphospholipid antibodies may be clinically useful as a valuable additional characteristic. The aim of this study was to compare several ELISA modifications with different chaotropic agents and calculation of avidity indices for the determination of anticardiolipin antibody (aCL) avidity. METHODS We examined 28 serum samples with positive IgG aCL by adapted ELISA using various concentrations of urea and sodium chloride as chaotropic agents and different dilution of sera. We tested these conditions of ELISA-a single diluted serum sample with fixed concentration of a chaotrope and a serially diluted serum in the constant concentration of a chaotropic agent. RESULTS We demonstrated that ELISA method for avidity determination based on a single dilution of serum in the presence of fixed concentration of chaotrope is convenient for determination of IgG aCL antibody avidity. Concentrations 6 and 8 mol/L of urea or 1 and 2 mol/L of NaCl were suitable for sufficient dissociation of immune complexes during ELISA procedure. CONCLUSION This way was in good agreement with more demanding procedures. Both urea and sodium chloride may be used as chaotropic agents. Reference values of avidity indices essential for interpretation of patients' results must be established individually for distinct assay conditions.

Abstract
The heart involvement in systemic autoimmune diseases represents a growing burden for patients and health systems. Cardiac function can be impaired as a consequence of systemic conditions and manifests with threatening clinical pictures or chronic myocardial damage. Direct injuries are mediated by the presence of inflammatory infiltrate which, even though unusual, is one of the most danger manifestations requiring prompt recognition and treatment. On the other hand, a not well-managed inflammatory status leads to accelerated atherosclerosis that precipitates ischemic disease. All cardiac structures may be damaged with different grades of intensity; moreover, lesions can appear simultaneously or more frequently at a short distance from each other leading to the onset of varied clinical pictures. The pathogenesis of heart damages in systemic autoimmune conditions is not yet completely understood for the great part of situations, even if several mechanisms have been investigated. The principal biochemical circuits refer to the damaging role of autoantibodies on cardiac tissues and the precipitation of immune complexes on endocardium. These events are finally responsible of inflammatory infiltration which leads to subsequent worsening of the previous damage. For these reasons, it appears of paramount importance a regular and deepened cardiovascular assessment to prevent a progressive evolution toward heart failure in patient affected by autoimmune diseases.

Abstract
The antiphospholipid syndrome (APS) is an autoimmune disease characterized by the occurrence of venous and/or arterial thrombosis and pregnancy morbidity in the presence of pathogenic autoantibodies known as antiphospholipid antibodies (aPL). APS may be associated with other diseases, mainly systemic lupus erythematosus (SLE). The presence or absence of SLE might modify the clinical or serological expression of APS. Apart from the classical manifestations, APS patients with associated SLE more frequently display a clinical profile with arthralgias, arthritis, autoimmune hemolytic anemia, livedo reticularis, epilepsy, glomerular thrombosis, and myocardial infarction. The management of patients with SLE and APS/aPL should include an accurate stratification of vascular risk factors. Low dose aspirin and hydroxychloroquine should be considered as primary prophylaxis. In high risk situations, such as surgery, prolonged immobilization, and puerperium, the prophylaxis should be potentiated with low molecular weight heparin. The challenge of treating patients with a previous vascular event (secondary prophylaxis) is the choice of treatment (anti-platelet agents, anticoagulation with vitamin K antagonists or combined therapy) and its duration, based on individual risk stratification and the site of vascular presentation. The role of novel anticoagulants in APS patients is still to be clearly defined. Novel approaches are needed since the prognosis of SLE patients with APS/aPL is still worse than that of SLE patients with negative aPL. The goal for the future is to improve the outcome of these patients by means of early recognition and optimal preventative treatment.

Abstract
Antiphospholipid syndrome is an autoimmune disorder characterized by vascular thromboses and pregnancy morbidity associated with antiphospholipid antibodies: lupus anticoagulant, IgG or IgM anticardiolipin or anti-beta 2-glycoprotein I. The kidney is one of the major target organs in antiphospholipid syndrome (APS). However, beyond the known involvement of the kidney in primary and associated APS, we may be observing a new form of APS within the context of renal failure. This review describes the classical kidney manifestations of APS and provides new considerations to be taken into account.

Abstract
The number of cases with spontaneous coronary artery dissection (SCAD) is considered to be being underestimated because of a large amount of SCAD leading to sudden death without previous diagnosis. Besides, not only in clinics but also in autopsy practice, correct diagnosis of SCAD is important to prevent forensic malpractice.The article is intended to discuss the pathological findings through the forensic point of view for improving the malpractice expertise in scope of clinicians' timely antemortem diagnosis according to risk factors and in scope of forensic pathologists' the cause of death determination ability according to macroscopical and microscopical findings of the autopsy.In 3 cases reported, the main characteristics were the female sex, pregnancy history and a sudden death without any trauma. However, although there are many women giving birth or using oral contraceptives, only some of them are facing with SCAD. This suggests the possibility of some hereditary factors, whereas hereditary characteristics may be understood in many different ways like hormone-releasing regulating mechanisms as well as immunity, morphology, or any other mechanism. For instance, autoimmunity has been also a hereditary underlying factor for vessel injury considered in presented cases.

Abstract
OBJECTIVE To investigate the association between the presence of aPL and/or LA and all-cause mortality among end-stage renal disease (ESRD) patients with and without SLE. METHODS We included ESRD patients >18 years old followed at an urban tertiary care centre between 1 January 2006 and 31 January 2014 who had aPL measured at least once after initiating haemodialysis. All SLE patients met ACR/SLICC criteria. APL/LA+ was defined as aCL IgG or IgM >40 IU, anti-β2glycoprotein1 IgG or IgM >40 IU or LA+. Deaths as at 31 January 2014 were captured in the linked National Death Index data. Time to death was defined from the first aPL measurement. RESULTS We included 34 SLE ESRD and 64 non-SLE ESRD patients; 30 patients died during the study period. SLE ESRD patients were younger [40.4 (12.5) vs 51.9 (18.1) years, P = 0.001] and more were women (88.2% vs 54.7%, P < 0.001) vs non-SLE ESRD patients. The frequency of aPL/LA+ was 24% in SLE and 13% in non-SLE ESRD (P = 0.16). Median (inter-quartile range) follow-up time was 1.6 (0.3-3.5) years in SLE and 1.4 (0.4-3.2) years in non-SLE, P = 0.74. The adjusted hazard ratio (HR) for all-cause mortality for SLE patients who were aPL/LA+ vs aPL/LA- was 9.93 (95% CI 1.33, 74.19); the adjusted HR for non-SLE aPL/LA+ vs aPL/LA- was 0.77 (95% CI 0.14, 4.29). CONCLUSION SLE ESRD patients with aPL/LA+ had higher all-cause mortality risk than SLE ESRD patients without these antibodies, while the effects of aPL/LA on mortality were comparable among non-SLE ESRD patients.

Abstract
Autoimmune diseases, such as rheumatoid arthritis and systemic lupus erythematosus, have a strong association with an increased risk of atherosclerotic cardiovascular diseases (ASCVD), particularly ischemic heart disease (IHD). A majority of the autoimmune conditions occur predominantly in women, and as women continue to experience a higher cardiovascular mortality compared to men, this potential added risk factor must be recognized. Inflammation and immune mechanisms have been shown to be an underlying mechanism for the development of atherosclerosis, thus sharing a common mechanism with rheumatologic conditions. There is an under recognition, in both patient and physician, of the increased cardiovascular (CV) risk within the autoimmune population, with present CV risk profile algorithms performing poorly in these patients. Traditional risk factors play a role in the development of IHD in the autoimmune patient, but their overall significance is unclear and does not fully explain the elevated CV risk. The role of inflammation and risk factors in autoimmune conditions, and their link to the elevated CV risk will be explored within this article.

Abstract
The pathogenicity of antibodies against β2-glycoprotein I (anti-β2GPI) depends on multiple factors such as subclass type, epitope binding and avidity. Due to their large heterogeneity, their impact on antiphospholipid syndrome (APS) onset is still not fully clarified. We studied the binding characteristics of IgG anti-β2GPI with known avidity from sera of 201 autoimmune patients (87 with APS, 67 with APS associated with systemic lupus erythematosus (SLE), 47 with only SLE) to six β2GPI peptides corresponding to amino acid clusters on domains I-II, II, III and III-IV by indirect ELISA and evaluated their association with clinical features of APS. Peptides A (LKTPRV; domain I-II), B (KDKATF; domain IV) and C (TLRVYK; domain III) were derived from a hexapeptide phage display library previously shown to react with pathogenic monoclonal anti-β2GPI. Peptides D (NGPANSK; domain III), E (YNPLWFV; domain II) and F (KMDGNHP; domain III-IV) represent surface amino acid clusters on β2GPI. The percentage of patients positive for peptides were observed as follows: 30.3% for peptide D, 28.90% for B, 25.9% for C, 24.9% for E, 24.4% for F and 10.0% for A. The anti-peptide antibodies in studied serum samples were predominantly of heterogeneous avidity, followed by law avidity anti-peptide antibodies, whereas only a few were of high avidity. Positive and negative correlations were found between several anti-peptide antibodies and the rate of thrombosis. Our results indicated diverse reactivity of IgG anti-β2GPI to different epitopes on β2GPI. Classification of IgG anti-β2GPI into subgroups regarding epitope specificity and avidity could represent an additional tool in understanding their pathogenicity in APS.

Abstract
AIM We describe the clinical profile of elderly with primary antiphospholipid syndrome (APS). METHODS Charts of seven elderly patients diagnosed with APS between 1996 and 2012 were retrospectively assessed. RESULTS The mean age at diagnosis was 77 ± 6 years (67-84 years). Two patients had experienced frequent miscarriages. Five patients presented with deep venous thrombosis of the lower limb, one had venous thrombosis of the upper limb and brachiocephalic vein and another had a cerebral ischemic stroke. The antiphospholipid antibodies tests revealed the presence of significant amounts of anticardiolipin antibodies, 12 weeks apart, twice in four patients. The antibodies to β2-glycoprotein 1 were positive twice in two patients and lupus anticoagulant in one of these. All patients were treated with heparin and long-term anti-vitamin K and thrombosis was cleared in all cases. Two patients presented with bleeding complications: hematuria and hematoma of the buttock in one patient and rectal bleeding in another case. Two elderly developed a colon cancer and lymphoma 1 year later. CONCLUSION In this report, we report on primary APS in the elderly, to discuss its prevalence and the clinical significance of positive antiphospholipid antibodies in subjects over the age of 65 years.

Abstract
Autoimmune rheumatic diseases can affect the cardiac vasculature, valves, myocardium, pericardium, and conduction system, leading to a plethora of cardiovascular manifestations that can remain clinically silent or lead to substantial cardiovascular morbidity and mortality. Although the high risk of cardiovascular pathology in patients with autoimmune inflammatory rheumatological diseases is not owing to atherosclerosis alone, this particular condition contributes substantially to cardiovascular morbidity and mortality-the degree of coronary atherosclerosis observed in patients with rheumatic diseases can be as accelerated, diffuse, and extensive as in patients with diabetes mellitus. The high risk of atherosclerosis is not solely attributable to traditional cardiovascular risk factors: dysfunctional immune responses, a hallmark of patients with rheumatic disorders, are thought to cause chronic tissue-destructive inflammation. Prompt recognition of cardiovascular abnormalities is needed for timely and appropriate management, and aggressive control of traditional risk factors remains imperative in patients with rheumatic diseases. Moreover, therapies directed towards inflammatory process are crucial to reduce cardiovascular disease morbidity and mortality. In this Review, we examine the multiple cardiovascular manifestations in patients with rheumatological disorders, their underlying pathophysiology, and available management strategies, with particular emphasis on the vascular aspects of the emerging field of 'cardiorheumatology'.

Abstract
The heart is one of the most frequently affected organs in SLE. Any part of the heart can be affected, including the pericardium, myocardium, coronary arteries, valves, and the conduction system. In addition to pericarditis and myocarditis, a high incidence of CAD has become increasingly recognized as a cause of mortality, especially in older adult patients and those with long-standing SLE. Many unanswered questions remain in terms of understanding the pathogenesis of cardiac manifestations of SLE. It is not currently possible to predict the patients who are at greatest risk for the various types of cardiac involvement. However, with the rapid advancement of basic science and translational research approaches, it is now becoming easier to identify specific mutations associated with SLE. A better understanding of these genetic factors may eventually allow clinicians to categorize and predict the patients who are at risk for specific cardiac manifestations of SLE.

Abstract
Seronegative antiphospholipid syndrome (SNAPS) is an autoimmune disease present in patients with clinical manifestations highly suggestive of Antiphospholipid Syndrome (APS) but with persistently negative consensus antiphospholipid antibodies (a-PL). IgA anti-β2 Glycoprotein I (aB2-GPI) antibodies are associated with APS. However, they are not currently considered to be laboratory criteria due to the heterogeneity of published works and the use of poor standardized diagnostic systems. We have aimed to assess aPL antibodies in a group of patients with clinical manifestations of APS (C-APS) to evaluate the importance of the presence of IgA aB2GPI antibodies in APS and its relation with other aPL antibodies. Only 14% of patients with C-APS were positive for any consensus antibody, whereas the presence of isolated IgA aB2GPI antibodies was found in 22% of C-APS patients. In patients with arterial thrombosis IgA aB2GPI, antibodies were the only aPL antibodies present. Serologic profile in primary APS (PAPS) is different from systemic autoimmune disorders associated APS (SAD-APS). IgA aB2GPI antibodies are more prevalent in PAPS and IgG aB2GPI antibodies are predominant in SAD-APS. The analysis of IgA aB2GPI antibodies in patients with clinical manifestations of PAPS might avoid underdiagnosed patients and provide a better diagnosis in patients with SAD-APS. Laboratory consensus criteria might consider including analysis of IgA aB2GPI for APS diagnosis.

Abstract
Immunologic research into pathogenic mechanisms operating in autoimmune-mediated atherosclerosis initially focused on adaptive immunity. Current interest is directed to more basic inflammatory mechanisms. Chronic inflammation (innate immunity-associated) may trigger initial events that can lead to atherosclerotic cardiovascular disease. This chronic inflammation may start early in life and be perpetuated by classic atherosclerosis risk factors. Lipid peroxidation of low-density lipoprotein seems to be a key event in the initiation and progression of atherosclerosis. Oxidized low-density lipoprotein triggers inflammatory and immunogenic events that promote endothelial dysfunction and the synthesis and secretion of pro-inflammatory cytokines, leading to an autoimmune response capable of accelerating the intracellular accumulation of lipids within atherosclerotic plaques. Oxidized low-density lipoprotein binds β2-glycoprotein I to form circulating complexes found in both autoimmune and non-autoimmune atherosclerosis. It is likely that β2-glycoprotein I and/or these complexes contribute to early atherogenesis by stimulating pro-inflammatory innate immunity through endogenous sensors and inflammasome/interleukin-1 pathways. We discuss the chronic inflammatory (innate) and autoimmune (adaptive) responses operating in atherosclerosis to discern the role of autoimmunity in atherosclerotic cardiovascular disease.

Abstract
Background. It has been hypothesized that various infective agents may activate immune reactions as part of the atherosclerotic process. We aimed to investigate the interrelationship between chronic exposure to oral pathogens and immune-inflammatory response in patients with acute coronary atherothrombosis.
Patients and Methods. The study included 200 participants from Serbia: 100 patients with acute myocardial infarction (MI), and 100 age- and sex-matched controls. Antibodies to oral anaerobes and aerobes were determined as well as autoantibodies to endothelial cells, beta-2 glycoprotein I, platelet glycoprotein IIb/IIIa and anticardiolipin. Interleukin-6 (IL-6) and C-reactive protein (CRP) were measured. Results. The mean serum antibodies to oral anaerobes tended to be higher among subjects with MI (0.876 ± 0.303 versus 0.685 ± 0.172 OD, P < 0.001). Similarly, antibody levels against oral aerobes in patients were significantly different from controls. Antibodies against endothelial cell, beta-2 glycoprotein I, platelet glycoprotein IIb/IIIa, anticardiolipin along with CRP and IL-6 were highly elevated in patients. The levels of antibodies to oral bacteria showed linear correlation with tissue antibodies, CRP and IL-6.
Conclusion. Antibody response to chronic oral bacterial infections and host immune response against them may be responsible for the elevation of tissue antibodies and biomarkers of inflammation which are involved in acute coronary thrombosis development.

Abstract
Patient biological material for isolation of β2-glycoprotein I (β2GPI) and high avidity IgG anti-β2-glycoprotein I antibodies (HAv anti-β2GPI) dictates its full utilization. The aim of our study was to evaluate/improve procedures for isolation of unnicked β2GPI and HAv aβ2GPI to gain unmodified proteins in higher yields/purity. Isolation of β2GPI from plasma was a stepwise procedure combining nonspecific and specific methods. For isolation of polyclonal HAv aβ2GPI affinity chromatographies with immobilized protein G and human β2GPI were used. The unknown protein found during isolation was identified by liquid chromatography electrospray ionization mass spectrometry and the nonredundant National Center for Biotechnology Information database. The average mass of the isolated unnicked purified β2GPI increased from 6.56 mg to 9.94 mg. In the optimized isolation procedure the high molecular weight protein (proteoglycan 4) was successfully separated from β2GPI in the 1st peaks with size exclusion chromatography. The average efficiency of the isolation procedure for polyclonal HAv anti-β2GPI from different matrixes was 13.8%, as determined by our in-house anti-β2GPI ELISA. We modified the in-house isolation and purification procedures of unnicked β2GPI and HAv anti-β2GPI, improving the purity of antigen and antibodies as well as increasing the number of tests routinely performed with the in-house ELISA by ~50%.

Edema and fibrosis imaging by cardiovascular magnetic resonance: how can the experience of Cardiology be best utilized in rheumatological practice? Semin Arthritis Rheum 2014; 44:76-85. [PMID: 24582213 DOI: 10.1016/j.semarthrit.2014.01.005] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2013] [Revised: 10/19/2013] [Accepted: 01/17/2014] [Indexed: 12/19/2022]
Abstract
OBJECTIVES CMR, a non-invasive, non-radiating technique can detect myocardial oedema and fibrosis. METHOD CMR imaging, using T2-weighted and T1-weighted gadolinium enhanced images, has been successfully used in Cardiology to detect myocarditis, myocardial infarction and various cardiomyopathies. RESULTS Transmitting this experience from Cardiology into Rheumatology may be of important value because: (a) heart involvement with atypical clinical presentation is common in autoimmune connective tissue diseases (CTDs). (b) CMR can reliably and reproducibly detect early myocardial tissue changes. (c) CMR can identify disease acuity and detect various patterns of heart involvement in CTDs, including myocarditis, myocardial infarction and diffuse vasculitis. (d) CMR can assess heart lesion severity and aid therapeutic decisions in CTDs. CONCLUSION The CMR experience, transferred from Cardiology into Rheumatology, may facilitate early and accurate diagnosis of heart involvement in these diseases and potentially targeted heart treatment.

Abstract
BACKGROUND Anticardiolipin antibodies (antiCl), present in some patients with autoimmune disease, are associated with thrombosis, fetal loss, and other conditions. A significant proportion of patients with chronic periodontitis (CP) test positive for antiCl, likely because some periodontal pathogens contain antigens homologous to the target antigen of antiCl on the serum protein β-2 glycoprotein-I (β2GPI) and thus can induce antiCl by molecular mimicry. The authors hypothesized that treatment of periodontitis by scaling and root planing (SRP) could therefore decrease serum titers of antiCl in patients with CP. METHODS Thirty patients with CP received complete periodontal examinations at baseline including assessment of probing depth, attachment loss, gingival index, and plaque index. SRP was performed in two sessions at 2-week intervals. Eight weeks later, patients were reexamined. Blood samples were taken at baseline, 2 weeks after the initial therapy appointment, and 8 weeks after the completion of treatment for assessment of immunoglobulin (Ig)G and IgM antiCl levels. RESULTS All periodontal parameters improved significantly. Consistent with previous observations, five (16.7%) of the 30 patients exhibited elevated levels of IgG or IgM antiCl at baseline. Following treatment, the concentrations of IgG and IgM antiCl remained unchanged for the entire cohort of 30 patients. However, in the five patients with elevated antiCl at baseline, IgM antiCl concentrations decreased significantly (P = 0.0008) owing to therapy, while IgG antiCl did not. CONCLUSION The oral microflora is a likely source of antigen inducing antiCl in CP, since IgM antiCl levels can be reduced in the short term with conservative therapy.

Abstract
β2-glycoprotein I (β2GPI)-dependent anticardiolipin autoantibodies (aCl) are associated with thrombosis and fetal loss. Some microbial pathogens can induce pathogenic antibodies cross-reactive with β2GPI. Sera from a significant percentage of periodontitis patients contain aCl, and some periodontal pathogens contain antigens with peptide sequences having homology to β2GPI. We hypothesized that antibodies raised against P. gingivalis (aPg) contain pathogenic aCl that induce fetal resorption. We immunized mice with β2GPI, P. gingivalis W83, or an arg-gingipain-defective mutant of P. gingivalis (HF18). IgG fractions of aPg were immunoabsorbed to remove aCl-like antibodies (abs-aPg). IgG fractions were administered intravenously into tail veins of mated BALB/c females at day 0 of pregnancy. At day 15, the proportions of fetal resorptions were evaluated. The prevalence of fetal loss was significantly greater in the aPg group than in the control IgG group (21.2% vs. 5.3%, p = .001), and greater in the aPg group than in the abs-aPg group (21.2% vs. 12%, p < .05). There were no fetal resorptions observed in the aPgHF18 group (p = .0005 compared with aPg, p = .17 compared with control). aPg antibody contains activity consistent with pathogenic aCl, and the antigen inducing the antibodies that cause increased fetal loss may be on the arg-gingipain protease of P. gingivalis.

Abstract
Various autoimmune rheumatic diseases (ARDs), including rheumatoid arthritis, spondyloarthritis, vasculitis and systemic lupus erythematosus, are associated with premature atherosclerosis. However, premature atherosclerosis has not been uniformly observed in systemic sclerosis. Furthermore, although experimental models of atherosclerosis support the role of antiphospholipid antibodies in atherosclerosis, there is no clear evidence of premature atherosclerosis in antiphospholipid syndrome (APA). Ischemic events in APA are more likely to be caused by pro-thrombotic state than by enhanced atherosclerosis. Cardiovascular disease (CVD) in ARDs is caused by traditional and non-traditional risk factors. Besides other factors, inflammation and immunologic abnormalities, the quantity and quality of lipoproteins, hypertension, insulin resistance/hyperglycemia, obesity and underweight, presence of platelets bearing complement protein C4d, reduced number and function of endothelial progenitor cells, apoptosis of endothelial cells, epigenetic mechanisms, renal disease, periodontal disease, depression, hyperuricemia, hypothyroidism, sleep apnea and vitamin D deficiency may contribute to the premature CVD. Although most research has focused on systemic inflammation, vascular inflammation may play a crucial role in the premature CVD in ARDs. It may be involved in the development and destabilization of both atherosclerotic lesions and of aortic aneurysms (a known complication of ARDs). Inflammation in subintimal vascular and perivascular layers appears to frequently occur in CVD, with a higher frequency in ARD than in non-ARD patients. It is possible that this inflammation is caused by infections and/or autoimmunity, which might have consequences for treatment. Importantly, drugs targeting immunologic factors participating in the subintimal inflammation (e.g., T- and B-cells) might have a protective effect on CVD. Interestingly, vasa vasorum and cardiovascular adipose tissue may play an important role in atherogenesis. Inflammation and complement depositions in the vessel wall are likely to contribute to vascular stiffness. Based on biopsy findings, also inflammation in the myocardium and small vessels may contribute to premature CVD in ARDs (cardiac ischemia and heart failure). There is an enormous need for an improved CVD prevention in ARDs. Studies examining the effect of DMARDs/biologics on vascular inflammation and CV risk are warranted.

Abstract
Atherothrombosis is the major determinant of acute ischaemic cardiovascular events, such as myocardial infarction and stroke. Inflammatory processes have been linked to all phases of atherogenesis In particular, the identification of autoimmunity mediators in the complex microenvironment of chronic inflammation has become the focus of attention in both early and advanced atherogenic processes. Auto-antibodies against self-molecules or new epitopes generated by oxidative processes infiltrate atherosclerotic plaques and were shown to modulate the activity of immune cells by binding various types of receptors. However, despite mounting evidence for a pathophysiological role of autoantibodies in atherothrombosis, the clinical relevance for circulating autoantibodies in cardiovascular outcomes is still debated. This review aims at illustrating the mechanisms by which different types of autoantibodies might either promote or repress atherothrombosis and to discuss the clinical studies assessing the role of auto-antibodies as prognostic biomarkers of plaque vulnerability.

Abstract
AIM Periodontal diseases are associated with a variety of systemic diseases, including cardiovascular disease and stroke, and patients with periodontitis demonstrate elevated levels of anti-cardiolipin antibodies. We sought to determine if anti-cardiolipin antibodies from periodontitis patients induced monocyte chemotactic protein-1 production by human vascular endothelial cells. MATERIALS AND METHODS IgG was purified from sera from 53 subjects, including chronic and aggressive periodontitis patients and periodontally healthy controls, with elevated or normal IgG anti-cardiolipin levels. In addition, anti-cardiolipin antibodies were specifically removed from some sera by immunoabsorption. RESULTS We found that, irrespective of diagnostic category, IgG from subjects with elevated anti-cardiolipin induced significantly greater monocyte chemotactic protein-1 production by human vascular endothelial cells than IgG from those subjects with normal anti-cardiolipin titres. Removal of anti-cardiolipin from IgG preparations from periodontitis patients significantly reduced their ability to induce monocyte chemotactic protein-1. CONCLUSIONS Since elevated titres of anti-cardiolipin are found in a significantly greater proportion of patients with periodontitis than in periodontally healthy individuals, and these antibodies activate endothelial cells to produce monocyte chemotactic protein-1, they may explain some of the associations noted between periodontal infections and systemic conditions.

Abstract
Aortic atherosclerosis (AoA) defined as intima-media thickening or plaques and aortic stiffness (AoS) also considered an atherosclerotic process and defined as decreased vessel distensibility (higher pulse pressure to achieve similar degree of vessel distension) are common in patients with SLE. Immune-mediated inflammation, thrombogenesis, traditional atherogenic factors, and therapy-related metabolic abnormalities are the main pathogenic factors of AoA and AoS. Pathology of AoA and AoS suggests an initial subclinical endothelialitis or vasculitis, which is exacerbated by thrombogenesis and atherogenic factors and ultimately resulting in AoA and AoS. Computed tomography (CT) for detection of arterial wall calcifications and arterial tonometry for detection of increased arterial pulse wave velocity are the most common diagnostic methods for detecting AoA and AoS, respectively. MRI may become a more applicable and accurate technique than CT. Although transesophageal echocardiography accurately detects earlier and advanced stages of AoA and AoS, it is semi-invasive and cannot be used as a screening method. Although imaging techniques demonstrate highly variable prevalence rates, on average about one third of adult SLE patients may have AoA or AoS. Age at SLE diagnosis; SLE duration; activity and damage; corticosteroid therapy; metabolic syndrome; chronic kidney disease; and mitral annular calcification are common independent predictors of AoA and AoS. Also, AoA and AoS are highly associated with carotid and coronary atherosclerosis. Earlier stages of AoA and AoS are usually subclinical. However, earlier stages of disease may be causally related or contribute to peripheral or cerebral embolism, pre-hypertension and hypertension, and increased left ventricular afterload resulting in left ventricular hypertrophy and diastolic dysfunction. Later stages of disease predisposes to visceral ischemia, aortic aneurysms and aortic dissection. Even earlier stages of AoA and AoS have been associated with increased cardiovascular and cerebrovascular morbidity and mortality of SLE patients. Aggressive non-steroidal immunosuppressive therapy and non-pharmacologic and pharmacologic interventions for control of atherogenic risk factors may prevent the development or progression of AoA and AoS and may decrease cardiovascular and cerebrovascular morbidity and mortality in SLE.

Abstract
The presence of dendritic cells, antigen-presenting cells that link innate and adaptive immunity, is necessary to generate and maintain the production of antiphospholipid antibodies in response to exposed intracellular phospholipids on the outer surface of apoptotic cells. In turn, antiphospholipid antibodies enhance dendritic cell-induced inflammatory and proatherogenic responses in a number of conditions that are associated with accelerated atherosclerosis, including diabetes, chronic kidney disease, periodontal infections, and aging. While altering dendritic cells by modifying the ubiquitin-proteasome system enhances antiphospholipid antibody production and leads to development of accelerated atherosclerosis and autoimmune features, inducing tolerance by dendritic cell manipulation leads to decreased atherosclerosis and thrombosis. Therefore, further translational studies are needed to understand the interplay between dendritic cells and antiphospholipid antibodies, and to develop potential new therapies for antiphospholipid syndrome and atherosclerosis. Here we review current experimental and translational studies that have examined the role of dendritic cells in antiphospholipid antibody formation and in antiphospholipid-associated atherosclerosis and thrombosis.
