SLE and dsDNA

Ole Petter Rekvig
Systemic lupus erythematosus (SLE) is an inadequately defined syndrome. Etiology and pathogenesis remain largely unknown. SLE is on the other hand a seminal syndrome that has challenged immunologists, biologists, genetics, and clinicians to solve its nature. The syndrome is characterized by multiple, etiologically unlinked manifestations. Unexpectedly, they seem to occur in different stochastically linked clusters, although single gene defects may promote a smaller spectrum of symptoms/criteria typical for SLE...

BACKGROUND: Systemic lupus erythematosus (SLE) is characterized by alternating periods of activity and remission. A portion of the patients suffers from the chronically active form of the disease. The search for clinically useful markers of its activity is ongoing. At present, it is suggested that β2-microglobulin (β2M) may be useful in assessing SLE activity. OBJECTIVES: The objective of the paper was to investigate the relationship between serum β2M concentration and SLE activity...

A healthy 38-year-old woman developed sudden unilateral vision loss due to retrobulbar optic neuritis in the wake of varicella-zoster virus infection. She had no further central nervous system (CNS) lesions. Antinuclear antibodies (ANA) and anti-aquaporin 4 antibodies were found, consistent with neuromyelitis optica (NMO). Later, serial MRIs showed dynamic short-segment and long-segment myelitis lesions, ANA titre increased and additional autoantibodies were found including anti-dsDNA, anti-chromatin/nucleosome and antiphospholipid antibodies...

RATIONALE: Lupus erythematosus panniculitis (LEP) is a rare subset of lupus erythematosus. The incidence of LEP in systemic lupus erythematosus (SLE) ranges from 2% to 5%. In the previous literature, most LEP patients were women aged from 20 to 60 years, while pediatric cases were rare, all of whom appeared on their own without SLE.A rare LEP in a 10-year-old female child with severe SLE is presented. PATIENT CONCERNS: A 10-year-old girl was admitted to our hospital for marasmus and fatigue without other typical manifestations of SLE well before the appearance of skin lesions...

Although aberrant complement activation is involved in the pathogenesis of systemic lupus erythematosus (SLE), the role of complement regulatory proteins in disease activity of SLE remains limited. We enrolled the pediatric-onset SLE patients from our cohort study over 10 years. The clinical and laboratory data including SLEDAI disease activity score, and serum complement factor H (CFH), CFI, CD46, C5a, and C5b-9 in the active and remission phases were determined. Glomerular C5b-9 deposition as a complement activity marker was also examined...

Background Patients with systemic lupus erythematosus (SLE) may form clusters with clinical manifestations and autoantibodies. Objective The objective of this report is to study whether SLE patients with positive rheumatoid factor (RF) have a special clinical and/or serological profile. Methods A retrospective study of 467 SLE patients seen at a single rheumatology unit was conducted. Epidemiological data (age, gender, age at disease onset, ethnic background and tobacco use), clinical data (malar rash, photosensitivity, oral ulcers, discoid lesions, serositis, glomerulonephritis, convulsions, psychosis, hemolytic anemia, leukopenia, lymphocytopenia, arthritis and hypothyroidism) and serological profile (anti-dsDNA, anti-Ro/SS-A, anti-La/SS-B, anti-RNP, anti-Sm, IgG aCL, IgM aCL, lupus anticoagulant, direct Coombs and RF) were collected...

Objectives Outcomes of systemic lupus erythematosus (SLE) have significantly improved over the years. However, when there is major organ involvement, the outcomes can still be unfavorable. Outcomes of multitarget therapy using mycophenolate mofetil (MMF) and tacrolimus in patients with SLE who were refractory to standard therapy were assessed. Methods We retrospectively reviewed the Hanyang BAE lupus cohort to identify patients with biopsy-confirmed lupus nephritis (classes III, IV, or V) who failed to either achieve complete response with standard induction therapy or those who had a lupus flare after achieving a complete response with conventional induction therapy and subsequently were switched to multitarget combination therapy with MMF and tacrolimus...

BACKGROUND: Wiskott-Aldrich syndrome (WAS) is a rare primary immunodeficiency caused by mutations in WASp, a key regulator of cytoskeletal dynamics in hematopoietic cells. A high proportion of patients develop autoimmunity due to a breakdown in T and B cell tolerance. Moreover, excessive production of type-I interferon by plasmacytoid DCs contribute to autoimmune signs, however, the factors that triggers excessive innate activation have not been defined. OBJECTIVE: Neutrophils extracellular traps (NETs) emerged as major initiating factors in diseases such as systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA)...

Identifying new markers of disease flares in lupus nephritis (LN) that facilitate patient stratification and prognosis is important. Therefore, the aim of this study was to analyze whether urinary SIRT1 expression was altered in LN and whether SIRT1 values in urine could be valuable biomarker of disease activity. In a cohort study, urinary pellets from 40 patients diagnosed with systemic lupus erythematosus (SLE) were analyzed. Clinical measures of lupus activity were assessed. The expression of SIRT1 was quantified by quantitative PCR (qRT-PCR) and immunoblot, then compared between patients with active lupus nephritis, in remission and healthy controls...

Neuropsychiatric systemic lupus erythematosus (NPSLE) has a wide variety of neurologic and psychiatric features. NPSLE symptoms and the psychotic features of primary psychiatric disorders often overlap with each other. These psychotic features often mask and delay the diagnosis of NPSLE. We present the case of a 59-year-old female previously diagnosed with bipolar disorder and generalized anxiety disorder presenting with altered mental status (AMS), subsequently diagnosed with neuropsychiatric lupus. Initially, medication overdose was suspected as an empty bottle of trazodone was found beside her...

Systemic Lupus Erythematosus (SLE) is an autoimmune disease resulting in autoantibody production, immune complex deposition, and complement activation. The standard biomarkers such as anti-dsDNA and complements (C3 and C4) do not always correlate with active clinical SLE. The heterogeneity of SLE patients may require additional biomarkers to designate disease activity. Ninety SLE patients participated in this study. Evaluation of disease activity was achieved with the Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) and modified SLEDAI-2K...

Taking into consideration the multiparametric nature of systemic lupus erythematosus (SLE), the severity and variability of symptoms and the lack of effective therapeutic approaches, the present study took advantage of the recently described role of soluble major histocompatibility complex class II (sMHCII) molecules in maintaining tolerance to the organism and attempted to apply sMHCII proteins as a treatment to murine SLE experimental models in vitro as well as in vivo. After breaking tolerance to DNA in vitro, which was accompanied by development of specific anti-dsDNA antibodies, syngeneic or allogeneic sMHCII molecules, purified from healthy mouse serum, could significantly reduce the specific antibody levels and drive the system towards immunosuppression, as assessed by specific marker analysis on T cells and cytokine production by flow cytometry and ELISA respectively...
