Systemic lupus erythematosus: disease activity may influence the release of endothelial microparticles?

To evaluate blood-borne endothelial microparticles (EMPs) in women with SLE and correlated these to disease activity as defined by the SLEDAI-2K score. The study takes cross-sectional design. A total of 90 age-matched women were recruited including: G1 (healthy volunteers, n = 30), G2 (women with SLE and low disease activity (SLEDAI-2K score ≤4; n = 30) and G3 (women with SLE and moderate/high disease activity (SLEDAI-2K score>4; n = 30). Blood was collected in 3.2% sodium citrate. Subsequently, the microparticles were purified by ultracentrifugation and labeled with anti-CD51/61 and anti-Annexin-V antibodies. Quantification and phenotyping were performed using flow cytometry. The number of EMPs was significantly higher in SLE patients compared with controls (P = 0.0178). When SLE patients were stratified according to disease activity, the number of EMPs was significantly increased in women with moderate-to-high disease activity compared with controls (P = 0.0074). We observed a correlation between the number of EMPs and age (r = −0.34; P = 0.0123) and between the number of EMPs and SLEDAI-2K score (r = 0.30; P = 0.04). Our results suggest that the SLE causes increased EMPs release, especially in patients with SLEDAI-2K score greater than 4. Although measurement of the EMPs could be useful in distinguishing patients with SLE from health controls, they have limited value in differentiating between SLE subtypes.

CONCLUSIONS: This study demonstrates that autophagic activity of podocytes is a crucial factor in renal injury by directly affecting the function of podocyte; thus, inhibiting this activity during the early stages of LN is implicated as a potential therapeutic strategy for delaying the progression of LN. Also, clinical application in LN needs to consider patients' pathological type and drugs' comprehensive effectiveness. PMID: 29446059 [PubMed - as supplied by publisher]

These molecules have been established to participate in numerous critical cellular settings, including differentiation, development, and function of immune cells. As an important suppressor...

We present a consensus report pertaining to the improved clarity of definitions and classification of glomerular lesions in lupus nephritis that derived from a meeting of 18 members of an international nephropathology working group in Leiden, Netherlands, in 2016. Here we report detailed recommendations on issues for which we can propose adjustments based on existing evidence and current consensus opinion (phase 1). New definitions are provided for mesangial hypercellularity and for cellular, fibrocellular, and fibrous crescents.

Summary Antiphospholipid syndrome (APS) is an autoimmune disease characterized by antiphospholipid antibodies (aPL) associated with thrombosis and/or pregnancy morbidity. Most APS events are directly related to thrombotic events, which may affect small, medium or large vessels. Other clinical features like thrombocytopenia, nephropathy, cardiac valve disease, cognitive dysfunction and skin ulcers (called non-criteria manifestations) add significant morbidity to this syndrome and represent clinical situations that are challenging. APS was initially described in patients with systemic lupus erythematosus (SLE) but it can occ...

This report describes a 48-year-old female with SLE and antiphospholipid syndrome complicated by recurrent thrombosis on anticoagulation. A large left atrial mass lesion was detected on echocardiography during a work-up for leg burning. Infective endocarditis could not be confirmed, and hence left atrial mass lesion was the most likely diagnosis. The patient was managed surgically and the pathology report revealed fibrin networks in a pattern similar to that of thrombosis, characteristic of NBTE.Cardiology 2018;139:208 –211

The levels of 758 miRNAs were evaluated in the serum of 26 SSc patients as compared to 9 healthy controls by using an Openarray platform. Patients fulfilling the ACR/EULAR 2013 classification criteria were classified in relation to the extent of skin fibrosis as limited cutaneous (lcSSc) or diffuse cutaneous SSc (dcSSc); patients fulfilling the classification criteria without skin fibrosis will be referred to as non-cutaneous SSc (nc...
