Background: Designation of disease activity is serious for the management of systemic lupus erythematosus (SLE). Serum level of β2 microglobulin (β2M) may be associated with illness activity in SLE disease. Since the role of β2M for assessing of illness activity in SLE is not completely clear, the current study aimed to discern evaluation of β2M in patients with SLE and its correlation with sickness activity. Materials and Methods: In this case-control study, 50 patients with SLE disease and 25 healthy individuals were selected in Imam Khomeini Hospital in central of Urmia. Blood samples were collected safely from patients, serum was removed, and β2M measured using an ELISA method. The results for other parameters including C reactive protein, C3, C4, anti dsDNA and erythrocyte sedimentation rate were obtained from patients’ medical record. Data analyzed using appropriate statistical tests including Mann-Whitney U test, Independent f-test, Kruskal-Wallis, and Spearman used for analysis of data. Results: In the current study, a significant difference was seen between two groups in terms of β2M (p < 0.001). Remarkable correlation was seen between the level of β2M with disease activity (p < 0.001). Furthermore, there are significant relevancy between the level of β2M with 24-hour urine protein, ESR, disease activity score, and CRP (p < 0.05). Conclusion: The results revealed that serum amount of β2M in SLE patients is higher compared to healthy ones, which is significantly correlated to score of illness activity, CRP, and ESR in patients with SLE disease. Hence β2M might be an excellent serological marker helping the prediction of sickness activity and inflammation in SLE patients.

The role of C-reactive protein (CRP) in systemic lupus erythematosus (SLE) as an inflammatory marker is still controversial. Recently, more sensitive methods, such as high sensitive CRP (hs-CRP) have been used to detect micro-inflammation. The role of hs-CRP in lupus flare has not been documented well. We conducted this study to examine the correlation between hs-CRP serum concentrations and disease activity in lupus. Ninety-two SLE patients and 49 healthy controls contributed to our study. Most confounding factors influencing the hs-CRP values were excluded. Disease activity was estimated using the SLE Disease Activity Index (SLEDAI-2K). hs-CRP values were determined using an enzyme-linked immunosorbent assay (ELISA) kit. Serum values of hs-CRP were significantly higher ( p < 0.001, z = 3.29) in patients compared with healthy controls. The cutoff point for hs-CRP between patients and controls was 0.93 mg/L (Youden’s Index = 0.39). There was no correlation between hs-CRP serum levels and disease activity. Furthermore, hs-CRP values did not correlate with any of the laboratory parameters, except for C3 ( p = 0.003, rs = −0.2) and C4 ( p = 0.02, rs = −0.1). Although hs-CRP serum levels were significantly higher in lupus patients compared with healthy controls, it seems that this marker is not a good indicator for disease activity.

Serum Exosomes

Systemic lupus erythematosus (SLE) is a multi-system autoimmune disease characterized by continuous inflammation and the production of autoantibodies. Exosomes, acting as a critical tool for communication between cells, are involved in the pathogenesis of SLE, particularly in inflammation and immune imbalance. In this study, we aimed to extract and confirm the pro-inflammatory effect of serum exosomes in SLE. Then, we attempted to find differentially expressed exosomal microRNAs in the serum of healthy subjects and SLE patients via miRNA microarray analysis and validated the target exosomal microRNA, exosomal miR-451a, which expression level decreased in serum of SLE patients by RT-qPCR. Furtherly, we analyzed the correlation between exosomal miR-451a and disease activity, kidney damage and typing, and traditional medicine therapy. Finally, we investigated the intercellular communication role of exosomal miR-451a in SLE by co-culture assay in vitro. Taken together, our study demonstrated that downregulated serum exosomal miR-451a expression correlated with SLE disease activity and renal damage as well as its intercellular communication role in SLE which provided potential therapeutic strategies.

Abstract Circular RNAs (circRNAs) are a class of non-coding RNAs that regulate gene expression by acting as competitive endogenous RNAs (ceRNAs) and modulating gene transcription. Several studies support the implication of circRNAs in a variety of human diseases, but research on the role of circRNAs in systemic lupus erythematosus (SLE) is lacking. In a study recently published in Clinical Science (2018), Zhang et al. identified hsa_circ_0012919 as a potential biomarker of disease activity in SLE patients. The authors observed different circRNA expression between SLE patients and healthy controls, an association with clinical variables and with the abnormal DNA methylation present in SLE CD4+ T cells. Finally, Zhang et al. demonstrated that hsa_circ_0012919 acts as a miRNA sponge for miR-125a-3p, regulating the gene expression of targets RANTES and KLF13 that are involved in the physiology and pathophysiology of acute and chronic inflammatory processes. These findings support the role of circRNAs in the pathophysiology of SLE.

Significant Difference

The erythropoietin receptor (EpoR) stimulates erythrocyte proliferation after erythropoietin binding. EpoR belongs to the cytokine receptor superfamily and can be found on macrophages and endothelial cells. As there are no data on the role of EpoR systemic autoimmune diseases, we investigated the role of soluble EpoR (sEpoR) in patients with systemic lupus erythematosus (SLE). In a cross-sectional study we recorded clinical characteristics, disease activity (SLEDAI-2K) and organ damage (SDI). sEpoR, autoantibodies and cytokines were measured by enzyme-linked immunosorbent assay (ELISA) in SLE patients (n = 100) and compared with a rheumatoid arthritis (RA) cohort (n = 57) and a cohort with non-inflammatory back pain (NIBP; n = 89). Data were analysed with non-parametric techniques. We found no significant difference in sEpoR levels across the SLE, RA and NIBP groups and sEpoR levels were similar in patients with (6% of SLE and 31% of RA) or without anaemia. sEpoR levels were unrelated to haemoglobin levels, SLEDAI-2K or SDI scores, but in both cohorts correlated with levels for C-reactive protein (CRP), interleukin-6 (IL-6), tumour necrosis factor (TNF) and IL-1 (all P < 0.001). sEpoR levels are not involved in anaemia or erythropoietin resistance in SLE and RA patients, but closely mirror the underlying inflammatory process. This suggests that increased shedding of sEpoR during inflammation occurs at other sites than bone marrow.

Pathogenic Role

Background:IL-10 plays a key role in systemic lupus erythematosus (SLE) pathogenesis, promoting B-cell response. IL10 is mainly secreted by regulatory T-cells, but follicular helper T-cells (TFH), also produce it. We previously identified a subset of CCR6+IL-7R+T-cells in human tonsils providing IL-10-dependent B-cell help. These CCR6+T-cells were able to produce IL-10, inducing IgG production.Objectives:to investigate a possible role of CD4+CCR6+IL7R+T-cells in SLE pathogenesis.Methods:37 patients fulfilling the ACR criteria for SLE have been included. Disease activity was assessed by 2k-SLEDAI. PBMC were analyzed by flow cytometry, using specific lineage markers. CCR6+IL7R+T-cells purified from total PBMC of SLE patients or healthy donors (HD) were co-cultured with autologous CD20+B-cells. IL-10, Il-17, total IgG and anti-dsDNA antibodies titers in patients serum and culture supernatants were assessed by ELISA. Embedded sections of lymph nodes from 8 SLE patients were analyzed by immunofluorescence (IF).Results:IL10 levels were significantly higher in SLE patients (Fig 1A). CD4+CCR6+IL7R+T-cells were significantly increased in SLE, in particular in those with higher disease activity and higher IL10 levels. CD4+CCR6+IL7R+T-cells levels associated with anti-dsDNA positivity. CCR6+IL7R+T-cells of SLE patients induced production of IgG and anti-dsDNA IgG (in anti-dsDNA + patients) from autologous B-cells, providing spontaneous help for autoantibody productionex vivo(Fig 1B-C). The IF study of lymph nodes of SLE patients showed that IL-10-producing CCR6+T-cells were highly abundant and co-localized with B-cells at follicle margins.Fig 1Conclusion:our study revealed a novel population of extra-follicular B-helper T-cells, which produce IL-10 and could play a prominent pathogenic role in SLE. Further studies will clarify if this potentially pathogenic cell population might represent a possible future therapeutic target.References:[1]Facciotti F. J Allergy Clin Immunol. 2016; Geginat J.
