Abstract

Background Early cardiac damage is very common in RA patients, but it is usually subclinical. Therefore, finding a non invasive method for the early detection and treatment of cardiac damage in autoimmune diseases is particularly important.

Objective To evaluate left ventricular function changes in rheumatoid arthritis (RA) patients with preserved left ventricular ejection fraction (LVEF) using left ventricular pressure-strain loop (LV-PSL) technology and to explore the correlation between myocardial work (MW) and disease activity.

Methods A total of 62 RA patients with preserved LVEF, treated at Wujin Hospital Affiliated with Jiangsu University from January 2021 to September 2023, were included. Patients were categorized into low (25), medium (18), and high (19) disease activity groups based on the 28 joint disease activity score (DAS28). A control group of 29 healthy individuals was also established. LV-PSL technology assessed left ventricular global longitudinal strain (GLS) and MW parameters: global constructive work (GCW), global wasted work (GWW), global work index (GWI), and global work efficiency (GWE). Cor relations between MW parameters, GLS, LVEF, and DAS28 scores were analyzed.

Results There were no significant differences in general data between study and control groups (p>0.05). However, labora tory indicators (RF, CRP, ESR) showed significant differences (p<0.05). GWI, GCW, GWE, and GLS were significantly lower in the high disease activity group compared to controls (p<0.05). GWI, GCW, and GWE were positively correlated with LVEF and absolute GLS, while GWW correlated negatively with LVEF (p<0.05).

Conclusion RA disease activity is closely associated with impaired myocardial work. LV-PSL technology effectively moni tors myocardial function abnormalities in RA patients, providing valuable insights for clinical management.

Key PointsMyocardial work is significantly impaired in RA patients with high disease activity. Left ventricular pressure-strain loop (LV-PSL) technology effectively assesses cardiac function in this patient population. Increased disease activity correlates with reduced myocardial work parameters.

Introduction

Rheumatoid arthritis (RA) is a systemic autoimmune disease that increasingly raises concerns among clinicians regarding extra-articular manifestations. The cardiac is one of the com mon target organs affected by RA, with involvement of the pericardium, vasculature, myocardium, and valves. A 10-year matched cohort study found that patients with RA were

Abstract

Hypercholesterolemia (Hch) is a risk factor for cerebrovascular and neurodegenerative diseases, manifesting with symptoms that vary depending on damage to specific brain regions. Hch triggers inflammatory responses and cell death. However, the progression of these processes in relation to the duration of Hch and the location of pathology in the central nervous system remains unclear. Therefore, we aimed to investigate (1) the impact of age and duration of Hch on neuroinflammatory responses and programmed cell death in the brain and (2) the intensity of these processes in various brain areas during Hch. In this study, we used 3-, 6-, and 12-month-old male Apo E−/−/LDLR−/− double-knockout mice and age-matched wild-type C57BL/6 mice (control group). Concentrations of cytokines IL-1β, IL-4, and IL-6, as well as apoptotic mediators AIF and Cas-3, were measured using enzyme-linked immunosorbent assay in the whole brain and separately in the prefrontal cortex (PFCx), hippocampus (HIP), and striatum (STR). The results showed that the Hch-induced release of cytokines IL-1β and IL-6, decreased expression of IL-4, and elevated level of apoptotic markers AIF and Cas-3 correlated with Hch duration. The inflammatory response and expression of apoptotic markers were more pronounced in the HIP and STR compared to the PFCx. Our results indicate a correlation between the neurodegenerative effects of Hch and its duration and highlight the varying susceptibility of different brain areas to Hch-induced damage.

Graphical Abstract

Hypercholesterolemia (Hch)-induced inflammatory response and programmed cell death activation in the prefrontal cortex (PFCx), hippocampus (HIP), and striatum (STR) of 3-, 6-, and 12-month-old, Apo E−/−/LDLR−/− double-knockout mice. In three age-groups the Hch-induced response involved release of inflammatory cytokines (IL-1ß and IL-6), a decrease of anti-inflammatory (IL-4) cytokine level, and activation of programmed cell death markers (AIF and Cas-3). The inflam matory response and expression of apoptotic markers were more pronounced in the HIP and STR, compared to the PFCx.

Abstract

In humans, glucocorticoid resistance is attributed to mutations in the glucocorticoid receptor (GR). Most of these mutations result in decreased ligand binding, transactivation, and/or translocation, albeit with normal protein abundances. However, there is no clear genotype‒phenotype relationship between the severity or age at disease presentation and the degree of functional loss of the receptor. Previously, we documented that a GR+/− rat line developed clinical features of glucocorticoid resistance, namely, hypercortisolemia, adrenal hyperplasia, and salt-sensitive hypertension. In this study, we analyzed the GR+/em4 rat model heterozygously mutant for the deletion of exon 3, which encompasses the second zinc finger, including the domains of DNA binding, dimerization, and nuclear localization signals. On a standard diet, mutant rats exhibited a trend toward increased corticosterone levels and a normal systolic blood pressure and heart rate but presented with adrenal hyperplasia. They exhibited increased adrenal soluble epoxide hydroxylase (sEH), favoring an increase in less active poly unsaturated fatty acids. Indeed, a significant increase in nonactive omega-3 and omega-6 polyunsaturated fatty acids, such as 5(6)-DiHETrE or 9(10)-DiHOME, was observed with advanced age (10 versus 5 weeks old) and following a switch to a high-salt diet accompanied by salt-sensitive hypertension. In thoracic aortas, a reduced soluble epoxide hydrolase (sEH) protein abundance resulted in altered vascular reactivity upon a standard diet, which was blunted upon a high-salt diet. In conclusion, mutations in the GR affecting the ligand-binding domain as well as the dimerization domain resulted in deregu lated GR signaling, favoring salt-sensitive hypertension in the absence of obvious mineralocorticoid excess.
