Mesenchymal stem cells and T cells in the formation of Tertiary Lymphoid Structures in Lupus Nephritis.

Tertiary lymphoid structures (TLS) develop in the kidneys of lupus-prone mice and systemic lupus erythematosus (SLE) patients with lupus nephritis (LN). Here we investigated the presence of mesenchymal stem cells (MSCs) in the development of TLS in murine LN, as well as the role of human MSCs as lymphoid tissue organizer (LTo) cells on the activation of CD4+ T cells from three groups of donors inc...

Molecular (Me)micry?

Molecular mimicry between humans and the microbiota is more common than appreciated. As presented by Martin Kriegel and colleagues (Greiling et al., 2018), this mimicry may mislead the immune system and trigger a friendly fire on our own tissues, as in the case of microbial-Ro60 and the autoimmune disease lupus.

Serum human epididymis protein 4 is a predictor for developing nephritis in patients with systemic lupus erythematosus: A prospective cohort study.

It has been demonstrated that serum human epididymis protein 4 (HE4) is a useful biomarker for differentiating lupus nephritis (LN) from systemic lupus erythematosus (SLE). However, it remains unclear whether HE4 can be used to predict the development of LN.

Identification of a neutrophil-related gene expression signature that is enriched in adult systemic lupus erythematosus patients with active nephritis: Clinical/pathologic associations and etiologic mechanisms.

Both a lack of biomarkers and relatively ineffective treatments constitute impediments to management of lupus nephritis (LN). Here we used gene expression microarrays to contrast the transcriptomic profiles of active SLE patients with and without LN to identify potential biomarkers for this condition. RNA isolated from whole peripheral blood of active SLE patients was used for transcriptomic profi...

Subcutaneous Panniculitis-Like T-Cell Lymphoma Versus Lupus Erythematosus Panniculitis: Distinction by Means of the Periadipocytic Cell Proliferation Index.

The distinction between subcutaneous panniculitis-like T-cell lymphoma (SPTCL) and lupus erythematosus (LE) panniculitis is remarkably challenging. Rimming by lymphocytes with an elevated Ki-67 cell proliferation index has been forwarded as a potential diagnostic finding in biopsies of SPTCL but has not been rigorously compared with biopsies from patients with LE panniculitis. Nineteen and 17 exam...

A successful treatment of severe systemic lupus erythematosus caused by occult pulmonary infection-associated with hemophagocytic syndrome: A case report.

A 27-year-old woman with a history of systemic lupus erythaematosus (SLE) developed hemophagocytic syndrome (HPS) secondary due to an unrecognized infection that led to severe SLE with a prolonged recovery.

Systemic lupus erythematosus in a patient with Noonan syndrome-like disorder with loose anagen hair 1: More than a chance association.

Systemic lupus erythematosus (SLE) has been reported among patients with RASopathy. Five patients have been reported: three with SHOC2 variants, one with a PTPN11 variant, and one with a KRAS variant. SHOC2 variant might represent a relatively common predisposing factor for SLE among the RASopathy genes. However, the clinical details were only reported for two patients, while information on the re...

Correlation of Thyroid Autoantibodies,System Lupus Erythematosus Immunologic Indicators and Disease Activity in SLE with HT.

To investigate the correlation of disease activity and thyroid indicators ,immunologic markers of system lupus erythematosus (SLE) in SLE with Hashimoto's thyroiditis (HT).

Cognitive dysfunction improves in systemic lupus erythematosus: Results of a 10 years prospective study.

Cognitive impairment (CI) has been described in 3-80% of Systemic lupus erythematosus (SLE) patients but only short-term studies evaluated its over-time changes, suggesting that CI is usually a stable finding. We aimed at evaluating the changes of SLE-related CI in a 10-years prospective single center cohort study.

Disease activity, autoantibodies, and inflammatory molecules in serum and cerebrospinal fluid of patients with Systemic Lupus Erythematosus and Cognitive Dysfunction.

To determine if cognitive dysfunction in patients with systemic lupus erythematosus (SLE) derives from an inflammatory process with continuing disease activity, and increased levels of autoantibodies and inflammatory molecules in serum and cerebrospinal fluid (CSF).

Renal protective effect of antiplatelet therapy in antiphospholipid antibody-positive lupus nephritis patients without antiphospholipid syndrome.

We sought to evaluate the effect of antiplatelet therapy in addition to conventional immunosuppressive therapy for lupus nephritis (LN) patients positive for antiphospholipid antibodies (aPL) without definite antiphospholipid syndrome (APS).

Coexistence of chronic cutaneous lupus erythematosus and frontal fibrosing alopecia.

Lupus erythemathosus is a chronic, relapsing disease with acute, subacute, and chronic lesions. Effluvium telogen occurs in the setting of systemic activity of the disease, and cicatricial alopecia results from discoid lesionsin on the scalp. Other types of alopecia, like alopecia areata, may rarely be found in lupus. Frontal fibrosing alopecia is characterized by frontotemporal hairline recession...

The Effect of History of Abnormal Pap Smear or Preceding HPV infection on the Humoral Immune Response to Quadrivalent Human Papilloma virus (qHPV) Vaccine in Women with Systemic Lupus Erythematosus.

To determine if natural human papillomavirus (HPV) infection would induce an anamnestic response to quadrivalent (qHPV) vaccine in women with Systemic Lupus Erythematosus (SLE).

Activated partial thromboplastin time derivative curves: helpful diagnostic tool in mixing test interpretation.

: The mixing test is used to evaluate whether prolonged activated partial thromboplastin time (APTT) is due to an inhibitor or a factor deficiency. The coagulation reaction is demonstrated with APTT derivative curves on the ACL TOP series. We aimed to determine the utility of APTT derivative curves in the mixing test process. The plasma of a patient was mixed with normal plasma in a 1 : 1 rati...

Monocyte chemoattractant protein-1 promoter-2518 G allele increases renal damage in systemic lupus erythematosus patients: result from a meta-analysis.

Reports about the monocyte chemoattractant protein-1 (MCP-1) promoter-2518A/G polymorphism and systemic lupus erythematosus (SLE) were controversial. This study aimed to assess the association between MCP-1 promoter-2518A/G polymorphism and SLE via meta-analysis.

Administration of activated lymphocyte-derived DNA accelerates and aggravates lupus nephritis in B6/lpr mice: a new approach to modify a lupus murine model.

B6/lpr mouse strain is a well-known systemic lupus erythematosus murine model characterized by uncontrolled lymphoproliferation and autoantibody production. However, it displays a delayed and mild development of lupus nephritis (LN), which is not conducive to the research of the pathogenesis and therapeutic strategies of this condition. Our previous study demonstrated that activated lymphocyte-der...

Cytomegalovirus aggravates the autoimmune phenomenon in systemic autoimmune diseases.

Human Cytomegalovirus (CMV), because of its ability to extensively manipulate host immunity during active infection, has been suggested to be involved in autoimmunity. However, its influence on T-cells and cytokines in systemic autoimmune diseases like systemic lupus erythematosus (SLE) and systemic sclerosis (SSc) is indistinct.

A Critical Review on Obstetric Follow-up of Women Affected by Systemic Lupus Erythematosus.

 To review the existing recommendations on the prenatal care of women with systemic lupus erythematosus (SLE), based on currently available scientific evidence.

Tuftsin-phosphorylcholine (TPC) equally effective to methylprednisolone in ameliorating lupus nephritis in a mice model.

The role of helminth treatment in autoimmune diseases is constantly growing. Systemic lupus erythematosus (SLE) is a multi-system autoimmune disease with challenging treatment options. Tuftsin phosphorylcholine (TPC) is a novel helminth-based compound that modulates the host immune network.

Associations of Circulating CXCR3PD-1CD4T cells with Disease Activity of Systemic Lupus Erythematosus.

Which helper CD4 T cell subset contributes to autoantibodies generation and severity of end-organ involvement in lupus patients remains to be explored. Our research aims to investigate the roles of circulating Tfh (cTfh) cell subsets and corresponding CXCR5 Th cells in lupus patients and their correlation with SLEDAI.

Association of objectively measured physical activity and sedentary time with arterial stiffness in women with systemic lupus erythematosus with mild disease activity.

To examine the association of objectively measured physical activity (PA) intensity levels and sedentary time with arterial stiffness in women with systemic lupus erythematosus (SLE) with mild disease activity and to analyze whether participants meeting the international PA guidelines have lower arterial stiffness than those not meeting the PA guidelines.

Galectin-3 deficiency drives lupus-like disease by promoting spontaneous germinal centers formation via IFN-γ.

Germinal centers (GC) are important sites for high-affinity and long-lived antibody induction. Tight regulation of GC responses is critical for maintaining self-tolerance. Here, we show that Galectin-3 (Gal-3) is involved in GC development. Compared with WT mice, Gal-3 KO mice have more GC B cells and T follicular helper cells, increased percentages of antibody-secreting cells and higher concentra...

Impaired TGF-β signaling in patients with active systemic lupus erythematosus is associated with an overexpression of IL-22.

The mechanisms leading to the disruption of self-tolerance in systemic lupus erythematosus (SLE) remain elusive. Herein, we aimed to decipher the molecular basis of the impaired response of mononuclear cells to TGF-β1. The Smad3-pathway was explored on CD3+ lymphocytes in either active or non active SLE patients. An impaired transcription of TGF-β1 target genes was demonstrated in the CD3+ lymph...

Role of Direct Immunofluorescence in Cutaneous Small-Vessel Vasculitis: Experience From a Tertiary Center.

Skin is commonly affected by vasculitic process and often subjected to biopsy. Cutaneous vasculitis can be either primary or part of a systemic vasculitic process. This study was conducted to evaluate the diagnostic utility of direct immunofluorescence (DIF) in determination of etiology of cutaneous vasculitis. All histologically proven cases of cutaneous vasculitis over the past two and half year...

Prevalence, persistence and clinical correlations of classic and novel antiphospholipid antibodies in systemic lupus erythematosus.

aPL are frequently present in SLE. In a well characterized SLE cohort we aimed at investigating the prevalence of aPL and assessing their analytical performance and clinical association by testing criteria specificities including LA, aCL IgG and IgM, anti-β2-glycoprotein 1 (antiβ2GP1) IgG and IgM, as well as the non-criteria aPS-PT IgG and IgM and anti-β2GP1 domain 1 (aD1) IgG.
