Methotrexate use, not interleukin 33, is associated with lower carotid intima-media thickness in patients with rheumatoid arthritis

Effect of anti-inflammatory therapy on vascular biomarkers for subclinical cardiovascular disease in rheumatoid arthritis patients

OBJECTIVE

To assess the effect of 4 years of anti-inflammatory therapy on markers of subclinical vascular disease in rheumatoid arthritis patients.

METHODS

Carotid intima media thickness (IMT), augmentation index (AIx@75) and pulse wave velocity (PWV) measurements were performed repeatedly in 61 RA patients (30 early RA starting with csDMARDs and 31 established RA starting with adalimumab) for 4 years. These markers were also measured in 29 controls with osteoarthritis at baseline (BL).

RESULTS

IMT and AIx@75 at BL were higher in RA compared to OA, while PWV was higher in OA. In RA patients, AIx@75 and PWV decreased in the first 6 months after starting anti-inflammatory therapy. At 48 M, the level of AIx@75 remained lower than before therapy, while PWV at 48 M was comparable to BL (AIx@75: BL 28% (95% confidence interval 25-30%), 6 M 23% (20-26%), 48 M 25% (22-28%); PWV: BL 8.5 (7.8-9.2), 6 M 8.0 (7.1-8.9), 48 M 8.6 (7.6-9.6) m/s). IMT remained stable. There was an effect of disease activity (longitudinally, adjusted for changes over time) on IMT, AIx@75 and PWV.

CONCLUSION

This study suggests modest beneficial changes in some surrogate markers of subclinical vascular disease after anti-inflammatory therapy. These changes were associated with improvement in disease activity markers. Whether or not these beneficial changes ultimately predict a reduction in clinicalcardiovascular endpoints remains to be established in prospective studies.

Effect of Anti-Rheumatic Drugs on Cardiovascular Disease Events in Rheumatoid Arthritis

Rheumatoid arthritis (RA) is an autoimmune disease characterized by erosive arthritis, which can involve multiple systems. Patients with RA may have a variety of comorbidities, including cardiovascular disease (CVD), lung cancer, lymphoma, infection, osteoporosis, fatigue, depression, colon cancer, breast cancer, prostate cancer, and Alzheimer's disease. Among these comorbidities, the incidence of CVD, lung cancer, lymphoma, infection, and osteoporosis is higher. CVD is a serious complication of RA. The risk of CVD and associated mortality rate in patients with RA is high, and the treatment rate is low. In addition to traditional risk factors, such as age, sex, blood pressure, and diabetes, RA is also associated with inflammation. Furthermore, therapeutic drugs for RA, including non-steroidal anti-inflammatory drugs, glucocorticoids, and disease-modifying anti-rheumatic drugs, have beneficial or harmful effects on cardiovascular events in patients with RA. This article discusses the effects of therapeutic drugs for RA on cardiovascular events.

Cumulative Inflammation and HbA1c Levels Correlate with Increased Intima-Media Thickness in Patients with Severe Hidradenitis Suppurativa

Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease that has been associated with a greater risk of metabolic and cardiovascular comorbidities. The aim of this study is to assess cardiovascular risk by means of intima-media thickness (IMT), metabolic syndrome, and other potential biomarkers in patients with severe hidradenitis suppurativa who are candidates for biologic therapy and to explore potentially associated factors. A cross-sectional study was performed. Body mass index (BMI), carotid intima-media thickness (IMT), and blood tests, including glycemic and lipid profile, insulin, vitamin D, and inflammation markers were performed. Fifty patients were included in the study; the male/female ratio was 3:2. The mean age was 38 years, and the mean disease duration was 21.8 years. The mean carotid IMT was 651.39 μm. A positive association of IMT with disease duration, tobacco consumption, and HbA1c levels was observed. HbA1c correlated with the age of onset, hypertension, metabolic syndrome, and glucose levels. Vitamin D levels inversely correlated with the number of areas affected. In conclusion, patients with severe HS present a higher cardiovascular risk, but it is not distributed equally within the patients: Tobacco consumption, inadequate glycemic control, and disease duration could be useful clinical and biochemical markers to identify patients at higher risk.

Factors associated with risk of major adverse cardiovascular events in patients with rheumatoid arthritis: a nationwide, population-based, case-control study

Objectives

To investigate factors associated with major adverse cardiovascular events (MACEs) in patients with rheumatoid arthritis (RA).

Methods

We conducted a nationwide, population-based, case-control study using Taiwan's National Health Insurance Research Database for 2003-2013. From 2004 to 2012, we identified 108,319 newly diagnosed RA patients without previous MACEs, of whom 7,580 patients (7.0%) developed MACEs during follow-up. From these incident RA patients, we included 5,994 MACE cases and 1:4 matched 23,976 non-MACE controls for analysis. The associations of MACEs with comorbidities and use of anti-rheumatic medications within 1 year before the index date were examined using conditional logistic regression analyses.

Results

Using multivariable conditional logistic regression analysis, the risk of MACE in RA patients was associated with use of golimumab [odd's ratio (OR), 0.09; 95% confidence interval (CI), 0.01-0.67], abatacept (OR, 0.13; 95% CI, 0.02-0.93), hydroxychloroquine (OR, 0.90; 95% CI, 0.82-0.99), methotrexate (OR, 0.72; 95% CI, 0.64-0.81), cyclosporin (OR, 1.43; 95% CI, 1.07-1.91), nonsteroidal anti-inflammation drugs (NSAIDs) (OR, 1.36; 95% CI, 1.27-1.46), antiplatelet agent (OR, 2.47; 95% CI, 2.31-2.63), hypertension (without anti-hypertensive agents: OR, 1.04; 95% CI, 0.96-1.12; with anti-hypertensive agents: OR, 1.47; 95% CI, 1.36-1.59), diabetes (OR, 1.27; 95% CI, 1.18-1.37), hyperlipidemia without lipid-lowering agents (OR, 1.09; 95% CI, 1.01-1.17), ischemic heart disease (OR, 1.20; 95% CI, 1.10-1.31), and chronic obstructive pulmonary disease (COPD) (OR, 1.12; 95% CI, 1.03-1.23) in the parsimonious model. The risk of MACE in RA patients also increased markedly in participants younger than 65 years with some comorbidities.

Conclusions

This population-based case-control study revealed that the use of golimumab, abatacept, hydroxychloroquine, and methotrexate were associated with a decreased risk of MACE development in newly diagnosed RA patients, while the use of cyclosporin, NSAIDs, and antiplatelet agents, and comorbidities, including hypertension, diabetes, hyperlipidemia without lipid-lowering agent therapy, ischemic heart disease, and COPD, were associated with an increased risk of MACE development in RA patients.

Metabolic Syndrome as a Factor Affecting on Intima-Media Thickness in Patients with Rheumatoid Arthritis

AIM: The aim of the study was to assess the association of the thickness of the intima-media complex with metabolic syndrome (MetS) and the degree of disease activity in patients with rheumatoid arthritis (RA). MATERIALS AND METHODS: The study included 101 patients with RA. All patients underwent a biochemical examination, the presence of MetS was determined, and the carotid thickness of the intima-media was determined. Statistical processing was performed using SPSS for Windows, version 18.0. RESULTS: Among 101 patients with RA, 41 (40.5%) had MetS. The frequency of detecting an increased value of the intima-media complex thickness was significantly higher in the group with MetS (n = 31 [75.6%]) than in the group without MetS (n = 21 [35.0%] p ≤ 0.0001). In the group of patients with MetS, the median carotid intima-media thickness (CIMT) was 1.2 mm, while this indicator in the group without MetS was 0.78 mm (U = 727, p = 0.001). In the regression model, MetS (B = 1.05; p = 0.027) and DAS28-ESR (B = 0.506; p = 0.021) were influenced by CIMT. CONCLUSIONS: The results of our study show the effect of MetS and RA activity on the increase of intima-media thickness.

Carotid artery intima-media thickness in adults receiving long-term home parenteral nutrition

BACKGROUND AND AIMS

Nutrition regimen in parenteral nutrition (PN) patients allows for a control of diet components. This may affect the process of lipid deposition in the vascular wall and change the risk of atherosclerosis. This study aims to examine the effect of long-term PN in adults on carotid intima-media thickness.

METHODS AND RESULTS

Thirty long-term PN patients (15 men and 15 women, mean age 64.7 ± 8.5 years) and thirty healthy volunteers (HV) (15 men and 15 women, mean age 64.9 ± 8.77 years) entered the study. Total amino acid and lipid formulation intake as well as duration of PN were calculated for PN patients. The common carotid artery intima-media thickness (CCA IMT) was examined in both groups. A lower CCA IMT (right/left mean: PN - 776 ± 121 vs HV - 848 ± 121 μm, p < 0.05; right/left maximum CCA IMT: PN - 935 ± 139 vs HV - 1024 ± 135 μm, p < 0.05) in PN patients was observed. A lower serum level of total (PN - 131.43 ± 43.12 vs HV - 209.2 ± 48.01 mg/dl, p < 0.05) and HDL (PN- 44.16 ± 12.45 vs HV - 72.57 ± 25.04 mg/dl, p < 0.05) cholesterol was reported in the PN patients. A correlation between patients' age and CCA IMT was observed in the control group, but not in the PN patients (right/left mean CCA IMT - PN: r = 0.48, p-0.007 vs HV: p-0.073; right/left maximum CCA IMT - PN: r = 0.48, p-0.008, vs HV: p-0.073).

CONCLUSIONS

Long term PN in adults is associated with lower CCA IMT. Long-term PN patients are a unique group in which carotid intima-media thickness does not correlate with the age.

Reduction of Silent Information Regulator 1 Activates Interleukin-33/ST2 Signaling and Contributes to Neuropathic Pain Induced by Spared Nerve Injury in Rats

Emerging studies have demonstrated that interleukin (IL)-33 and its receptor ST2 act as key factors in inflammatory diseases. Moreover, accumulating evidence has suggested that cytokines, including tumor necrosis factor (TNF)-α and IL-1β, trigger an inflammatory cascade. SIRT1 has been shown to suppress the expression of inflammatory cytokines. However, the effects of SIRT1 on IL-33/ST2 signaling and initiation of the inflammatory cascade via modulation of TNF-α and IL-1β by IL-33 remain unclear. In the present study, we found that the dorsal root ganglion (DRG) IL-33 and ST2 were upregulated in a rat model of spared nerve injury (SNI) and intrathecal injection of either IL-33 or ST2 antibodies alleviated mechanical allodynia and downregulated TNF-α and IL-1β induced by SNI. In addition, activation of SIRT1 decreased enhanced DRG IL-33/ST2 signaling in SNI rats. Artificial inactivation of SIRT1 via intrathecal injection of an SIRT1 antagonist could induce mechanical allodynia and upregulate IL-33 and ST2. These results demonstrated that reduction in SIRT1 could induce upregulation of DRG IL-33 and ST2 and contribute to mechanical allodynia induced by SNI in rats.
