BACKGROUND: Systemic lupus erythematosus (SLE) is a clinically heterogeneous autoimmune disease that is associated with great suffering for those affected, as well as high socioeconomic costs. Early diagnosis and adequate medical care are essential for a mild course of the disease. However, there is a lack of current figures and data on the care situation of patients in the area. METHODOLOGY: A total of 1546 general practitioners, rheumatologists, neurologists, nephrologists and dermatologists in Rhineland-Palatinate and Saarland were interviewed by fax or mail using a questionnaire regarding epidemiology, symptoms, therapy and therapy success...

A 42-year-old female patient was admitted to hospital due to acute neurological symptoms (dysarthria, disorientation). After exclusion of cerebral ischemia and hemorrhage an autoimmune encephalitis was diagnosed. Shortly before as an outpatient the suspicion of the presence of systemic lupus erythematosus (SLE) was voiced. The patient showed a constellation of high levels of inflammatory laboratory parameters and within a few days developed a severe pancytopenia. In the presence of all diagnostic criteria a secondary hemophagocytic lymphohistiocytosis (sHLH) was diagnosed and confirmed by a kidney biopsy during the course of the underlying SLE...

The genesis of subacute cutaneous lupus erythematosus (SCLE) is multifactorial and includes idiopathic, drug-related and paraneoplastic etiologies. This article reports the case of a 70-year-old female patient with paraneoplastic SCLE in whom a lung adenocarcinoma was detected during the extended examination. A paraneoplastic SCLE should be considered when a patient with SCLE presents with lesions in regions of the skin not exposed to sunlight and beginning B symptoms.

The TAM (TYRO3, MERTK, and AXL) family of receptor tyrosine kinases are pleiotropic regulators of adult tissue homeostasis maintaining organ integrity and self-renewal. Disruption of their homeostatic balance fosters pathological conditions like autoinflammatory or degenerative diseases including rheumatoid arthritis, lupus erythematodes, or liver fibrosis. Moreover, TAM receptors exhibit prominent cell-transforming properties, promoting tumor progression, metastasis, and therapy resistance in various cancer entities...

Systemic lupus erythematosus (SLE) is an autoimmune disease with variable clinical presentation and organ involvement. Early diagnosis and rapid achievement of low disease activity or remission reduces organ damage and improves prognosis. Therapeutic principles can be divided into so-called basic measures and immunosuppressive treatment. Novel drugs have been developed in recent years, with new classes of agents being added for the treatment of SLE. These include biologic therapies and approved therapeutic options for the treatment of lupus nephritis...

BACKGROUND: Multisystem inflammatory syndrome in children associated with COVID-19 (MIS-C) is a late complication of pediatric COVID-19, which follows weeks after the original SARS-CoV-2 infection, regardless of its severity. It is characterized by hyperinflammation, neutrophilia, lymphopenia, and activation of T cells with elevated IFN-γ. Observing the production of autoantibodies and parallels with systemic autoimmune disorders, such as systemic lupus erythematodes (SLE), we explored B cell phenotype and serum levels of type I, II, and III interferons, as well as the cytokines BAFF and APRIL in a cohort of MIS-C patients and healthy children after COVID-19...

The immune system is embedded in a network of regulatory systems to keep homeostasis in case of an immunologic challenge. Neuroendocrine immunologic research revealed several aspects of these interactions over the past decades, e.g. between the autonomic nervous system and the immune system. This review will focus on evidence revealing the role of the sympathetic nervous system (SNS) in chronic inflammation, like colitis, multiple sclerosis, systemic sclerosis, lupus erythematodes, and arthritis with a focus on animal models supported by human data...

A systematic assessment is critical for taking advantage of the current options for optimizing systemic lupus erythematosus (SLE) management. Without regular SLE activity measurements, treat to target and remission are empty words, and the EULAR recommendations therefore insist on these assessments. They rely on activity scores, such as SLEDAI, ECLAM and BILAG or more recently, EasyBILAG and SLE-DAS. Assessment is completed by organ-specific measurement methods and the evaluation of damage. In the study setting the classification criteria and combined endpoints for clinical testing are crucial, as is measurement of the quality of life...

BACKGROUND: We investigated the role of European League Against Rheumatism (EULAR)/American College of Rheumatology (ACR) classification criteria for the prediction of LN among children with SLE. METHODS: The data of the patients with childhood-onset SLE diagnosed based on 2012 Systemic Lupus International Collaborating Clinics (SLICC) criteria were retrospectively evaluated. Based on 2019 EULAR/ACR classification criteria, the scoring was done at the time of renal biopsy...

BACKGROUND: The inflammatory factor interferon (IFN)-γ is related to the occurrence and development of systemic lupus erythematosus (SLE). The vitamin D receptor (VDR) has an anti-inflammatory effect and its downregulation is involved in the onset of SLE. Our previous studies have confirmed that the expression of VDR in SLE peripheral blood mononuclear cells (PBMCs) is downregulated, which is negatively correlated with disease activity and inflammation. However, the mechanism underlying VDR downregulation in SLE is unknown...

Primary immune thrombocytopenia (ITP) in adult patients typically presents as a repeatedly relapsing disease in need of multiple lines of therapy. Here we report the clinical courses of two patients, an 82-year-old female and a 54-year-old male, with primary ITP after multiple relapses and exhausted standard therapies, which we treated with the myeloma-licensed anti-CD38 monoclonal antibody daratumumab in an off-label setting. Daratumumab is known to target preferentially plasmablasts, short-lived plasma cells and long-lived plasma cells, with the latter being the major source of antiplatelet autoantibodies...

The specific B-cell depleting anti-CD20 monoclonal antibody rituximab (RTX) is effective in terms of the treatment of various immune-mediated glomerulopathies. The administration of RTX has been shown to be reliable and highly effective particularly in patients with ANCA-associated vasculitis, which is manifested predominantly with non-nephrotic proteinuria. Stable long-term B-cell depletion is usually readily attained in such patients using standard dosing regimens. However, in patients with nephrotic syndrome and non-selective proteinuria, the RTX pharmacokinetics is altered profoundly and RTX does not maintain high enough levels for a sufficiently long period, which may render RTX treatment ineffective...

Insights into the immunopathogenesis of systemic lupus erythematosus (SLE) help to understand the complex disease patterns and to develop new treatment strategies. The disease manifestations essentially result from autoantibodies, immune complexes and cytokines. Particularly the propensity towards developing various autoantibodies is central to the disease itself; autoantibody specificities lead to highly variable organ manifestations. This review article delineates the clinically relevant state of knowledge on SLE pathogenesis, with the goal to establish a model useful for clinical practice, which also helps to classify the novel therapeutic approaches...
