Cardiovascular disease in patients with systemic autoimmune diseases: The relationship between self-perceived risk and actual risk.

INTRODUCTION: Autoimmune diseases are known to be associated with an elevated risk of cardiovascular diseases; however, there exists a lack of awareness regarding this increased risk among patients. OBJECTIVE: This study aimed to assess the prevalence of cardiovascular risk factors and events in various systemic autoimmune diseases, including Systemic Sclerosis (SSc), Systemic Lupus Erythematosus (SLE), Rheumatoid Arthritis (RA), and Sjögren's syndrome (SS), matched by age, sex, and disease duration. Additionally, the study aimed to evaluate the perceived and actual risks of cardiovascular disease among patients. METHODS: A cross-sectional self-reported survey on the patient's perspective of cardiovascular risk was conducted between January and June 2023. Sociodemographic and clinical data, including disease activity, were collected through medical records and questionnaires. Traditional cardiovascular risk factors and events were assessed, alongside the perceived cardiovascular risk. The SCORE calculation and Charlson Comorbidity Index (CCI) were employed for cardiovascular risk assessment. RESULTS: Survey responses from 180 patients (45 patients each with SSc, SLE, RA, and SS) with systemic autoimmune diseases revealed that 20% perceived a low risk, 23% perceived neither lower nor higher, and 56% perceived a higher risk of developing cardiovascular diseases in the next ten years. Only 45% agreed that their autoimmune disease could increase the risk of a heart attack, even in the absence of other risk factors, and 46.7% were unaware that NSAIDs pose a cardiovascular risk. An association between cardiovascular risk measured by SCORE, comorbidities, and risk perception was observed in RA, SSc, and SS patients, with no association found in SLE patients (p=0.27). Except for SS patients (p=0.02), no association between CCI and disease activity level was found. Regarding the influence of age, working status, and education in CVD risk perception, an association between CVD risk perception and age was observed (p=0.01), with patients over 40 years exhibiting a higher perception of CVD risk. No differences were found regarding working status (p=0.19) nor education level (p=0.06). CONCLUSIONS: Patients with SS, RA, and SSc displayed a heightened perception of cardiovascular risk, correlating with their actual risk and preexisting comorbidities. However, patients exhibited unawareness of certain cardiovascular risk behaviors. This underscores the need for tailored education programs on cardiovascular risk for autoimmune disease patients, to be implemented at the time of diagnosis and during follow-up in outpatient clinics.

Risk factors for cardiovascular disease in primary Sjögren's syndrome (pSS): a 20-year follow-up study.

INTRODUCTION: Primary Sjögren's syndrome (pSS) is a systemic autoimmune disease characterized by a chronic grade of inflammation. Cardiovascular events represent the major causes of morbidity and mortality in patients with inflammatory rheumatic diseases; however, the significance and prevalence of cardiovascular disease in patients with pSS remain unclear. OBJECTIVE: To determine the clinical significance of cardiovascular disease in pSS and analyze the risk of cardiovascular disease according to glandular/extraglandular involvement and positivity to anti-Ro/SSA and/or anti-La/SSB autoantibodies. METHODS: A retrospective study including patients diagnosed with pSS fulfilling the 2016 ACR/EULAR classification criteria was followed and evaluated in our outpatient clinic between 2000 and 2022. The prevalence of cardiovascular risk factors with pSS was evaluated, and a possible association with clinical and immunological characteristics, the treatments received, and the impact on cardiovascular disease were determined. Univariate and multivariate regression analyses were performed in an attempt to determine potential risk factors associated with cardiovascular involvement. RESULTS: A total of 102 pSS patients were included. Eighty-two percent were female, with a mean age of 65±24 years and a disease duration of 12.5 ±6 years. Thirty-six patients (36%) had at least one cardiovascular risk factor. Arterial hypertension was diagnosed in 60 (59%) patients, dyslipidemia in 28 (27%), diabetes in 15 (15%), obesity in 22 (22%), and hyperuricemia in 19 (18%). History of arrhythmia was found in 25 (25%), conduction defects in 10 (10%), arterial peripheral vascular disease in 7 (7%), venous thrombosis in 10 (10%), coronary artery disease in 24 (24%), and cerebrovascular disease in 22 (22%) of patients. Patients with extraglandular involvement had a higher prevalence of arterial hypertension (p=0.04), dyslipidemia (p=0.003), LDL mean values (p=0.038), hyperuricemia (p=0.03), and coronary artery disease (p=0.01) after adjusting for age, sex, disease duration, and the significant variables in the univariate analysis. Patients with Ro/SSA and La/SSB autoantibodies had a substantially higher risk of hyperuricemia (p=0.01), arrhythmia (p=0.01), coronary artery disease (p=0.02), cerebrovascular disease (p=0.02), and venous thrombosis (p =0.03). In the multivariate logistic regression analysis, higher odds of cardiovascular risk factors were associated with extraglandular involvement (p=0.02), treatment with corticosteroids (p=0.02), ESSDAI>13 (p=0.02), inflammatory markers including ESR levels (p 0.007), and serologic markers such as low C3 levels (p=0.03) and hypergammaglobulinemia (p=0.02). CONCLUSIONS: Extraglandular involvement was associated with a higher prevalence of arterial hypertension, dyslipidemia, hyperuricemia, and coronary artery disease. Anti-Ro/SSA and anti-La/SSB seropositivity was associated with a higher prevalence of cardiac rhythm abnormalities, hyperuricemia, venous thrombosis, coronary artery disease, and cerebrovascular disease. Raised inflammatory markers, disease activity measured by ESSDAI, extraglandular involvement, serologic markers including hypergammaglobulinemia and low C3, and treatment with corticosteroids were associated with a higher risk for cardiovascular comorbidities. Key Points • Patients with pSS are vulnerable to cardiovascular risk factors. There is an interconnection between extraglandular involvement, disease activity, inflammatory markers, and cardiovascular risk comorbidities. • Anti-Ro/SSA and anti-La/SSB seropositivity was associated with a higher frequency of cardiac conduction abnormalities, coronary artery disease, venous thrombosis, and stroke. • Hypergammaglobulinemia, elevated ESR, and low C3 are associated with a higher prevalence of cardiovascular comorbidities. • Valid risk stratification tools to help with prevention and consensus on the management of CVDs in pSS patients are warranted.

Clinical phenotype in scleroderma patients based on autoantibodies.

Objective: We aimed to characterize the clinical phenotype of patients with SSc based on autoantibodies (topoisomerase antibody (Scl-70), ACA and ANA). Methods: We included patients with SSc who fulfilled the 2013 ACR/EULAR criteria, with disease duration ≤15 years. Six groups of patients were defined: ACA-lcSSC, Scl-70-lcSSc, ANA-lcSSc, Scl-70-dcSSc, ANA-dcSSc and ACA-dcSSc patients. We compared the different groups of patients. In the ANA subgroup, we included patients negative for SSc-specific antibodies (Scl-70 and ACA). We assessed the following: risk of interstitial lung disease (ILD), myositis, scleroderma renal crisis, cardiac involvement, gastrointestinal involvement, pulmonary hypertension, treatment, cancer and all-cause mortality. Results: One hundred and thirteen SSc patients were included: 72 (64%) females, 82 (73%) lcSSc and 31 (27%) dcSSc. Among patients with lcSSc, 43 (52%) were ACA+, 16 (19%) Scl-70+ and 23 (28%) ANA+, and among patients with dcSSc, 13 (42%) patients were Scl-70+, 11 (35%) ANA+ and 7 (23%) ACA+. Scl-70-lcSSc patients had a significantly shorter time from RP to SSc diagnosis (P = 0.04), higher CRP (P = 0.04), renal scleroderma crisis (P = 0.02), ILD (P = 0.03) and diastolic dysfunction (P = 0.04) than ANA-lcSSc patients. Scl-70-dcSSc patients had a higher rate of myositis (P = 0.04), renal crisis (P = 0.03), CRP elevation (P = 0.002), ILD (P = 0.04), pericardial effusion (P = 0.03) and cancer (P = 0.04) than ANA-dcSSc patients. The risk of ILD was higher in Scl-70 patients during the first 10 years than in ACA+ and ANA+ patients (P = 0.03 and P = 0.02, respectively). The risk of major organ involvement was higher in Scl-70+ patients, followed by ANA+ and ACA+ patients, throughout 15 years of follow-up. All-cause mortality was higher in dcSSc patients than in lcSSc patients, but no differences were found regarding antibody positivity. Conclusion: We have characterized the clinical phenotype of patients based on autoantibodies: Scl-70 patients show the greatest risk of major organ involvement, followed by ANA+ patients and ACA+ patients. The risk of ILD in Scl-70+ patients suggests that these patients should be monitored closely, irrespective of skin involvement. These results might provide new ways to help with the early diagnosis and management and in assessment of the prognosis of the disease.

Atypical Debut of Granulomatosis with Polyangiitis as Acute Tonsilitis and Strawberry Gum: A Case Report.

BACKGROUND: Granulomatosis with polyangiitis (GPA) is a systemic necrotizing vasculitis characterized by necrosis, granulomatous inflammation, and vasculitis. It is characterized by the triad of the upper and lower respiratory system, lung, and kidney disease. Although it is usually a multisystemic disease, limited forms have also been described, and otolaryngological involvement is the first manifestation in up to 80-95% of the cases. CASE PRESENTATION: In this report, we describe the case of an ANCA negative patient with a limited form of GPA that presented a necrotic lesion confined to the right tonsil compatible with granulomatosis with polyangiitis, which later presented positive ANCA antibodies. Oral lesions may be the initial manifestation of GPA, and systemic involvement can be presented within weeks or months. Although the oral manifestations have been well described, the initial presentation with oral lesions is very rare, and presentation with oropharyngeal manifestation is even rarer. This disease is generally characterized by anti-neutrophil cytoplasmic antibodies (ANCA); however, there are rare cases with negative ANCA. CONCLUSION: The diagnosis was established based on the clinical presentation and the histopathological findings of the characteristic inflammatory pattern.
