Parvovirus B19 infections in adults are usually associated with nonspecific and mild symptoms. However, cases presenting with a lupus-like syndrome have been described, leading to the hypothesis that parvovirus infection can induce connective tissue disease. Various histopathologic features of cutaneous manifestations of parvovirus have been reported, including features which overlap with those of connective tissue disease. Herein, we discuss an unusual case of Parvovirus  B19 infection in a middle-aged woman...

Systemic Lupus Erythematosus (SLE) is a chronic systemic inflammatory disease. Autoantibodies (autoAbs) against double-stranded DNA (ds DNA), the hallmark of lupus, are produced and maintained by the interaction between auto-reactive B cells and CD4(+) T cells. This interplay is controlled by the CD28/CD80-86/CTLA-4 axis. Here we investigated whether selective blockade of CD28-CD80/86 co-stimulatory interactions abrogates lupus nephritis development in a murine model of SLE. To this aim, NZB/NZW F1 mice were treated for 3 months, either with an anti-CD28 Fab' fragment or a control Fab'-IgG...

Disease of systemic lupus erythematosus (SLE) and periodontal disease (PD) shares the common multiple characteristics. The aims of the present study were to evaluate the prevalence and severity of periodontal disease in Chinese SLE patients and to determine the association between SLE features and periodontal parameters. A cross-sectional study of 108 SLE patients together with 108 age- and sex-matched healthy controls was made. Periodontal status was conducted by two dentists independently. Sociodemographic characteristics, lifestyle factors, medication use, and clinical parameters were also assessed...

Childhood-onset systemic lupus erythematosus (cSLE) is a rare, multisystem and potentially life-threatening autoimmune disorder with significant associated morbidity. Evidence-based guidelines are sparse and management is often based on clinical expertise. SHARE (Single Hub and Access point for paediatric Rheumatology in Europe) was launched to optimise and disseminate management regimens for children and young adults with rheumatic diseases like cSLE. Here, we provide evidence-based recommendations for diagnosis and treatment of cSLE...

OBJECTIVES: IFN-γ, CXCL16 and uPAR have recently been regarded as potential biomarkers in systemic lupus erythematosus (SLE). However, few researches have focused on the comparison of these three markers in SLE. We conducted this study to evaluate their role as biomarkers of disease activity and renal damage. METHODS: We enrolled 50 SLE patients with or without lupus nephritis (LN) and 15 healthy control subjects. The levels of IFN-γ, CXCL16, uPAR in serum, urine and renal tissues were detected by ELISA or immunohistochemistry...

INTRODUCTION: Interleukin-37 (IL-37) has been proved to be a fundamental natural suppressor of innate immunity and inflammatory responses in autoimmune diseases such as systemic lupus erythematous (SLE). The purpose of this study was to assess serum IL-37 level in SLE patients and its correlation with disease activity and clinical and laboratory manifestations of SLE patients. PATIENTS/METHODS: The serum level of IL-37 was assessed and analyzed in 100 SLE patients and 50 healthy controls by using enzyme-linked immunosorbent assay (ELISA)...

The classification of a population by a specific trait is a major task in medicine, for example when in a diagnostic setting groups of patients with specific diseases are identified, but also when in predictive medicine a group of patients is classified into specific disease severity classes that might profit from different treatments. When the sizes of those subgroups become small, for example in rare diseases, imbalances between the classes are more the rule than the exception and make statistical classification problematic when the error rate of the minority class is high...

B cells play a crucial role in the pathogenesis of autoimmune diseases, such as systemic lupus erythematosus (SLE). However, the relevance of the metabolic pathway in the differentiation of human B cell subsets remains unknown. In this article, we show that the combination of CpG/TLR9 and IFN-α markedly induced the differentiation of CD27(+)IgD(+) unswitched memory B cells into CD27(hi)CD38(hi) plasmablasts. The response was accompanied by mammalian target of rapamycin complex 1 (mTORC1) activation and increased lactate production, indicating a shift to glycolysis...

Antagonists of tumor necrosis factor-alpha (ATNF) are used for the treatment of multiple diseases such as psoriatic arthritis, Crohn's disease, ankylosing spondylitis and juvenile idiopathic arthritis, usually, when they are refractory to first-line treatment(1). The use of ATNF has been associated with the induction of autoimmune diseases such as systemic lupus erythematosus-like disease, vasculitis, sarcoidosis-like diseases and, recently, acute granulomatous tubulointerstitial nephritis. We report a case of acute nongranulomatous tubulointerstitial nephritis in an HLA-B27-positive patient with axial spondyloarthritis and Crohn's disease being treated with adalimumab...

Autoimmune diseases (ADs) are a heterogeneous groups of diseases that occur as a results of loss of tolerance to self antigens. While the etiopathogeneis remain obscure, different environmental factors were suggested to have a role in the development of autoimmunity, including infections, low vitamin D levels, UV radiation, and melatonin. Interestingly, such factors possess seasonal variation patterns that could influence disease development, severity and progression. Vitamin D levels which reach a nadir during late winter and early spring is correlated with increased disease activity, clinical severity as well as relapse rates in several disease entities including multiple sclerosis (MS), non-cutaneous flares of systemic lupus erythematosus (SLE), psoriasis, and rheumatoid arthritis (RA)...

Lupus mastitis is an uncommon manifestation of systemic lupus erythematosus (SLE) that affects the subcutaneous fat in the breast, much like lupus panniculitis, but additionally involves the mammary gland. We report on two women for whom lupus mastitis was the initial manifestation of SLE and provide a literature review of 34 additional cases reported in the Anglo-Saxon and French literature since 1971, making this the largest review to date. Lupus mastitis (LM) can manifest clinically as subcutaneous masses that may be painful, or may present cutaneous involvement such as thickening and discolouration...

BACKGROUND: Identifying and treating the cause of pulmonary symptoms in HIV patients with underlying systemic lupus erythematosus (SLE) can be very challenging. Delays in diagnosing active SLE in HIV patients can lead to significant morbidity and even mortality. We report the case of an HIV-positive woman with SLE who presented with severe respiratory distress. CASE PRESENTATION: A 42-year-old HIV-positive woman presented with a 7-month history of anorexia, progressive dyspnoea, and a productive cough...

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease with no known cure that affects at least five million people worldwide. Monozygotic twin concordance and familial aggregation studies strongly suggest that lupus results from genetic predisposition along with environmental exposures including UV light. The majority of the common risk alleles associated with genetic predisposition to SLE map to genes associated with the immune system. However, evidence is emerging that implicates a role for aberrant DNA repair in the development of lupus...

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease affecting multiple organs. A complex interaction of genetics, environment, and hormones leads to immune dysregulation and breakdown of tolerance to self-antigens, resulting in autoantibody production, inflammation, and destruction of end-organs. Emerging evidence on the role of these factors has increased our knowledge of this complex disease, guiding therapeutic strategies and identifying putative biomarkers. Recent findings include the characterization of genetic/epigenetic factors linked to SLE, as well as cellular effectors...

Long non-coding RNAs can regulate gene transcription, modulate protein function, and act as competing endogenous RNA. Yet, their roles in systemic lupus erythematosus remain to be elucidated. We determined the expression profiles of lncRNAs in T cells of SLE patients and healthy controls using microarrays. Up to 1935 lncRNAs and 1977 mRNAs were differentially expressed. QRT-PCR showed downregulated uc001ykl.1 and ENST00000448942 in SLE patients. Expression of uc001ykl.1 correlated with erythrocyte sedimentation rate (ESR) and C-reactive protein, whereas ENST00000448942 level correlated with ESR and anti-Sm antibodies...
