Cardiovascular events risk in patients with systemic autoimmune diseases: a prognostic systematic review and meta-analysis

Management of Atherosclerotic Cardiovascular Risk in Inflammatory Bowel Disease: Current Perspectives

Inflammatory bowel disease (IBD) is a complex condition characterized by inflammation of the gastrointestinal system, encompassing Crohn's disease and ulcerative colitis. Patients diagnosed with IBD have an increased risk of atherosclerotic cardiovascular disease. This heightened risk can be attributed to a combination of mechanisms, including traditional risk factors, chronic inflammation, intestinal dysbiosis, increased risk of thrombosis, and the use of certain medications such as corticosteroids. There are significant gaps in current knowledge, particularly regarding the management of risk factors and the use of medications for cardiovascular disease prevention. Similarly, the cardiovascular effects of specific IBD therapies, particularly the newer ones, are not yet fully understood. This review focuses on the epidemiological evidence linking IBD with cardiovascular risk factors and cardiovascular disease. It describes the potential pathophysiological mechanisms underlying this association and examines the challenges involved in accurately assessing cardiovascular risk in these patients, including the utility of complementary tools such as subclinical atherosclerosis detection. Additionally, we consider the potential therapeutic implications for managing these patients. Finally, this review also underscores the importance of multidisciplinary collaboration. Effective teamwork among gastroenterologists, cardiologists, and general practitioners is essential for providing comprehensive care to patients with IBD.

Immunomodulation for accelerated atherosclerosis in rheumatoid arthritis and systemic lupus erythematosus

In the last decades, consisting evidence supported a close relationship between both innate and adaptive immune systems and the accelerated cardiovascular (CV) disease characterizing autoimmune diseases, such as systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA). Indeed, several cell lines involved in the pathogenesis of these autoimmune diseases, such as macrophages and dendritic cells, as well as different T and B lymphocyte subsets, and inflammatory cytokines, have been demonstrated to be directly involved in the mechanisms underlying early atherosclerotic arterial wall damage. Traditional CV risk factors play a concomitant role but do not sufficiently account for the increased prevalence of CV disease in these patients. Indeed, the pathophysiological link between RA and SLE and atherosclerosis is based on complex inflammatory pathways that interconnect these conditions and may explain the significant morbidity and mortality rates demonstrated in these patients, with consequent significant negative effects on quality of life and long-term survival. Consequently, it is intriguing to hypothesize that immunosuppressive drugs commonly used in the treatment of these pathologies may also exert an immunomodulatory and anti-inflammatory effect in mitigating the atherosclerotic damage that has been demonstrated to occur early in the initial stages of the disease. Recognizing risk factors, predicting occurrences and early intervention to prevent CV disease development have emerged as critical objectives in RA and SLE treatment. In this review, we aimed to provide an updated overview of the atherogenic effects exerted by the immune and inflammatory pathways involved in the pathogenesis of RA and SLE. Moreover, we examined the available evidence which may support the potential effects of immunosuppressive therapies in reducing CV damage and, consequently, CV disease risk in these patients.

Inflammation, Lp(a) and cardiovascular mortality: results from the LURIC study

OBJECTIVE

Lipoprotein(a) [Lp(a)] concentrations have been associated with cardiovascular risk. Recent studies suggested an interaction between systemic inflammation assessed via high-sensitivity C-reactive protein (hsCRP) and Lp(a). This study aimed to evaluate whether Lp(a), hsCRP, and interleukin-6 (IL-6) levels are associated with cardiovascular mortality in a German hospital-based cohort.

METHODS

Data were drawn from the Ludwigshafen Risk and Cardiovascular Health (LURIC) study, including 3,316 patients undergoing coronary angiography. Lp(a) was measured by immunoturbidimetry and categorized into three strata (< 50 mg/dL, n = 2668; 50-100 mg/dL, n = 482; > 100 mg/dL, n = 163). HsCRP was measured by immunonephelometry and categorized by intervals (1st < 1 mg/L, 2nd 1-2 mg/L and 3rd interval > 2 mg/L). IL-6 was measured by ELISA and categorized into two groups (1st < 3.2 ng/L, 2nd ≥ 3.2 ng/L). The primary outcome was cardiovascular disease (CVD) mortality, analyzed using Cox proportional hazards models and logistic regression.

RESULTS

Participants were predominantly male, with a mean age of 62.6 years. Extremely high Lp(a) (> 100 mg/dL) was associated with increased cardiovascular mortality (HR 1.5, 95% CI 1.06-2.12) compared to Lp(a) < 50 mg/dl. Both hsCRP (> 2 mg/L, HR 1.39, 95% CI 1.08-1.79 third vs. first interval) and more so IL-6 (HR 1.92, 95% CI 1.64-2.23, upper vs. lower half), were independently associated with higher CVD mortality. While hsCRP did not increase the Lp(a)-CVD mortality in stratified analysis, high IL-6 conferred an increased risk at Lp(a) levels > 100 mg/dL (HR 1.25, 95% CI 1.09-1.44).

CONCLUSION

HsCRP and IL-6 are associated with cardiovascular mortality. Markedly elevated Lp(a) is associated with an increased risk of cardiovascular mortality in the context of high systemic inflammation. Anti-inflammatory treatments may provide additional therapeutic benefits for individuals with high Lp(a).

Chronic Coronary Artery Disease: Wall Disease vs. Lumenopathy

Acute and chronic coronary artery disease (CAD) are interconnected, representing two facets of the same condition. Chronic CAD exhibits a dynamic nature, manifesting as stable or acute ischemia, or both. Myocardial ischemia can be transient and reversible. The genesis of CAD involves diverse anatomical and functional mechanisms, including endothelial dysfunction, arteriolar remodeling, capillary rarefaction, and perivascular fibrosis, though no single factor explains its heterogeneity. Chronic CAD is often stable but may present as symptomatic or asymptomatic (e.g., in diabetes) and affect various coronary compartments (epicardial or microcirculation). This complexity necessitates a reappraisal of our approach, as pathophysiological mechanisms vary and often overlap. A comprehensive exploration of these mechanisms using advanced diagnostic techniques can aid in identifying the dynamic processes underlying CAD. The disease may present as obstructive or non-obstructive, stable or unstable, underscoring its diversity. The primary source of CAD lies in the arterial wall, emphasizing the need for research on its components, such as the endothelium and vascular smooth muscle cells, and factors disrupting arterial homeostasis. Shifting focus from arterial luminal status to the arterial wall can provide insights into the genesis of atheromatous plaques, enabling earlier interventions to prevent their development and progression.

Unmasking the Hidden Threat: The Role of Left Ventricular Subendocardial Involvement in Autoimmune Rheumatic Disease

BACKGROUND

Late gadolinium enhancement (LGE) has been found in patients with autoimmune rheumatic disease (ARD). However, the prognostic implications of some specific LGE patterns in ARD patients remain unclear.

PURPOSE

To investigate the prevalence and prognostic significance of left ventricular (LV) subendocardium-involved LGE (LGEse) in a cohort of ARD patients.

MATERIALS AND METHODS

This retrospective study evaluated 176 patients diagnosed with ARD with clinically suspected cardiac involvement between 2018 and 2023. LV LGEse was defined as LGE involving the LV subendocardium that did not correspond to a coronary vascular distribution. The endpoints included a composite of cardiac death, heart failure-related admission, cardiogenic shock, and appropriate pacemaker or implantable cardioverter-defibrillator therapy.

RESULTS

Of the 176 consecutive patients, LV LGEse was observed in 22 patients (13%). During a median follow-up of 776 days (interquartile range, 395-1405 days), 20 patients (11%) experienced a composite endpoint. Compared with those without LV LGEse, the LV LGEse group had a greater proportion of men (64% vs. 14%; p < 0.001), lower LV ejection fraction (50% vs. 60%; p = 0.001), greater LV end-diastolic volume index (78 vs. 75; p = 0.043), and more adverse outcomes (32% vs. 8%; p = 0.005). In the univariable and multivariable Cox regression analyses, the LV LGEse showed independent prognostic value. In the sensitivity analyses, the prognostic difference in terms of LV subendocardial involvement remained.

CONCLUSION

In our cohort, LV subendocardial involvement, an underrecognized LGE pattern, was observed in 13% of all patients with autoimmune disease and indicated a worse prognosis.

Obesity: Friend or Foe in Sjögren's Syndrome Patients?

BACKGROUND/OBJECTIVES

In Sjögren's syndrome, exocrine glands are destructed in an autoimmune-mediated process. Obesity is known to influence a wide range of diseases. This study aimed to examine whether obesity has an impact on the disease course of our patients with Sjögren's syndrome.

METHODS

Out of the regularly followed-up patients, 125 were grouped based on their body mass index (BMI). Below a BMI of 25, they were listed as "non-obese" (n = 45), whereas above a BMI of 25, they were categorized as "obese" (n = 80). Demographic, laboratory, and immunological parameters; Sjögren's syndrome disease activity index; certain extraglandular manifestations; and treatment modalities were compared using biostatistical methods.

RESULTS

Among the examined cardiovascular and cerebrovascular co-morbidities, type 2 diabetes and hypertension were significantly more frequent in the obese group. Considering the associated further autoimmune disorders and extraglandular manifestations, in our patients, there were no significant differences between the two groups. Among laboratory parameters, gamma glutamil transferase, alanine transaminase, hemoglobin, hematocrit, lymphocyte rate, triglyceride, and c3 and c4 complement levels were significantly higher in the obese group, while the proportion of rheumatoid factor positivity and the neutrophil granulocyte rate were significantly lower. Immunoglobulin G, A, and M levels did not differ significantly between the two subsets. Obese patients needed steroid therapy significantly less frequently; however, statin therapy was remarkably more frequent in that group. Furthermore, the European League Against Rheumatism (EULAR) Sjögren's syndrome disease activity index (ESSDAI) was significantly lower in the group of overweight patients.

CONCLUSIONS

Our results suggest that several immunological parameters of obese patients are more favorable compared to those with normal body weight. Behind that, we might suspect either the beneficial effect of statin therapy and/or the obesity paradox.

Reviews for multimorbidity risk in people with inflammatory conditions: a qualitative study

BACKGROUND

People with inflammatory rheumatological conditions (IRCs) are at high risk of developing other conditions including cardiovascular disease (CVD) and mood disorders.

AIM

To explore perspectives of people with IRCs and healthcare practitioners (HCPs) on the content and delivery of a review consultation aimed at identification and management of multiple long-term conditions (mLTCs).

DESIGN & SETTING

Semi-structured interviews and focus groups with people with IRCs and HCPs in primary and secondary care.

METHOD

People with IRCs participated in individual semi-structured interviews by telephone or online platform. HCPs (including primary and secondary care clinicians) participated in online focus groups. Data were transcribed verbatim and analysed using inductive thematic analysis.

RESULTS

Fifteen people with IRCs were interviewed; three focus groups with HCPs were conducted. The following two main themes were identified: reflecting on the value of review consultations; and what would a new review look like? Overall, people with IRCs and HCPs reflected that access to reviews is inequitable, leading to duplication of reviews and fragmentation in care. People with IRCs, at times, had difficulty conceptualising reviews, especially when discussing their future risk of conditions. People suggested that preparation before the healthcare review could align patient and HCP agendas as part of a flexible and person-centred discussion.

CONCLUSION

Any review introduced for people with IRCs must move beyond a 'tick-box' exercise. To gain maximum value from a review, preparation from both patient and HCP may be required alongside a person-centred approach while ensuring they are targeted at people most likely to benefit.

Time Trend Analysis of Comorbidities in Ankylosing Spondylitis: A Population-Based Study from 53,142 Hospitalizations in Poland

BACKGROUND

(1) Influence of comorbidities on life expectancy and treatment outcomes is one of the main concerns of modern rheumatology, due to their rising prevalence and increasing impact on mortality and disability. The main objective of our study was to analyze the time trends and shifts in the comorbidity profile and mortality over 10 years in the Polish population with ankylosing spondylitis (AS). (2) Data from 2011-2020 years were acquired from the General Hospital Morbidity Study in the National Institute of Public Health-National Institute of Hygiene (NIH-PIB) as ICD-10 codes. Based on ICD10 codes, we calculated the percentage shares for comorbidities, with the relative risk ratios and odds ratios. We analyzed the hospitalization rates and mortality from the overlapping conditions. Also, we analyzed age and sex related differences in the clinical manifestations of AS patients. (3) Results: From 53,142 hospitalizations of patients with AS, we found that the male population presented higher rates of cardiovascular (2.7% vs. 1.3% p < 0.001) and pulmonary conditions (1.2% vs. 0.8% p < 0.025). Inflammatory bowel diseases were more common in the female population than in males (2.3% vs. 1.7%, p < 0.001). In the years 2011-2020, we observed a decline in the number of hospitalized patients due to cardiovascular (p < 0.001) and respiratory system conditions (p < 0.001), yet the relative risk and odd ratios remained high. In the years 2011-2020, 4056 patients received biological treatment (7%). The number of initiated biological therapies correlated negatively with the number of reported hospitalizations due to ischemic heart diseases (IHD) (p < 0.031, r = -0.8). Furthermore, in the logistic regression model, we found strong collinearity between cardiovascular and pulmonary comorbidities (VIF = 14; tolerance = 0.1); also, the number of reported IHD's correlated positively with the number of pulmonary infections (p < 0.031, r = 0.7) (4).

CONCLUSIONS

Cardiopulmonary comorbidities are a main factor associated with increased mortality in patients with AS, especially in hospitalized patients. The mortality rates among patients with AS admitted to hospital due to other conditions other than movement disorders exceed the populational risk. The number of biologically treated patients correlated negatively with hospital admissions due to IHD.
