Aortic Stiffness Is Associated With Left Ventricular Diastolic Dysfunction in Systemic Lupus Erythematosus: A Controlled Transesophageal Echocardiographic Study

Abstract BackgroundAortic stiffness and left ventricular (LV) diastolic dysfunction are common and associated with increased morbidity and mortality in systemic lupus erythematosus (SLE). HypothesisIn SLE, aortic stiffness and LV diastolic dysfunction may be associated. MethodsThis 6‐year‐duration, cross‐sectional, and controlled study was conducted in 76 SLE patients (69 women; mean age, 37 ± 12 years) and 26 age‐ and sex‐matched healthy controls. All subjects underwent clinical and laboratory evaluations and transesophageal echocardiography (TEE) to assess LV diastolic function and stiffness of the descending thoracic aorta using the pressure‐strain elastic modulus (PSEM). To validate results using PSEM, aortic strain, stiffness, and distensibility were assessed. ResultsPatients as compared with controls had higher PSEM (8.14 ± 4.25 vs 5.97 ± 2.31 U, P

In this study, the outer membrane from E. coli was isolated and used to produce OM particles with a diameter of approximately 100 nm. These prepared OM particles were applied in a thermophoretic immunoassay. First, outer membrane (OM) particles with lipopolysaccharides (LPS) and anti-LPS antibodies were used as a model to demonstrate proof of concept and the difference in E. coli thermophoresis was explained by the changes in the molecular surface area (A) and effective charge (σeff). The hydrodynamic size of the molecules was measured as a changing parameter, molecular surface area (A), by dynamic laser scattering...

ConclusionsAnti-DFS70 autoantibodies might be considered a biomarker to differentiate patients with SLE from ANA-positive individuals without autoimmune diseases.Key Points:• In a Latin American cohort, the anti-DFS70 was higher in individuals without autoimmune diseases compared with that in patients with SLE.• The anti-DFS70 might have utility as a biomarker of exclusion in patients with non-specific clinical signs of AARDs.

Authors: Ingawale DK, Mandlik SK Abstract Inflammation is a physiological intrinsic host response to injury meant for removal of noxious stimuli and maintenance of homeostasis. It is a defensive body mechanism that involves immune cells, blood vessels and molecular mediators of inflammation. Glucocorticoids (GCs) are steroidal hormones responsible for regulation of homeostatic and metabolic functions of body. Synthetic GCs are the most useful anti-inflammatory drugs used for the treatment of chronic inflammatory diseases such as asthma, chronic obstructive pulmonary disease (COPD), allergies, multiple sclerosis, te...

This study was conducted to investigate the association between common single-nucleotide polymorphisms (SNPs) in the MK and PTN gene and SLE susceptibility. A total of 989 subjects (496 SLE patients and 493 healthy controls) were included and genotyped for three MK SNPs and seven PTN SNPs in using improved multiple ligase detection reaction (iMLDR). Results have demonstrated no significant differences for genotype and allele frequencies in all 10 SNPs between SLE patients and healthy controls. Case-only analysis in SLE revealed that, in MK gene, the genotype frequency of AA/AG (rs35324223) was significantly lower in patien...

Ronnie and colleagues reported a case of a 10-year-old female with a history of systemic lupus erythematosus (SLE) complicated by hypertension and cardiomyopathy secondary to lupus who presented to the emergency department with a history of vision loss and headache [1]. The authors diagnosed the patient with posterior reversible encephalopathy syndrome (PRES). Although interesting, the diagnostic criteria for PRES was not met.
