Autoreactivity to mouse C1q in a murine model of SLE.
1995
A large proportion of systemic lupus erythematosus (SLE) patients develop glomerulonephritis, coincident with the appearance of autoantibodies to C1q, the Fc-recognizing collagen-like subcomponent of the first component of complement, C1. The MRL/lpr/lpr mouse is an established model for SLE, developing both antinuclear and anti-type II collagen autoantibodies, and rheumatoid factors(s), exhibiting reduced complement levels and later on developing glomerulonephritis and often arthritis. We report here an age-dependent decrease in serum C1q levels coincident with the development of IgG2b autoantibodies reactive with mouse C1q in MRL/lpr/lpr mice. Unlike IgG2b, although high levels of IgM, Ig…
Analysis of Epitope Spreading over an Eleven-year Period in a Patient with Systemic Lupus Erythematosus: CASE REPORT
1998
During a period of more than eleven years serum samples of a patient with Systemic Lupus Erythematosus were collected and analyzed for anti-nuclear autoantibodies. High titer of anti-La/SS-B were detectable in all serum samples. The La/SS-B epitopes remained constant. Besides anti-La/SS-B antibodies all serum samples contained traces of anti-Ro/SS-A including anti-Ro52 and anti-Ro60 antibodies. During disease flares anti-Ro/SS A antibodies were upregulated and anti-dsDNA antibodies appeared, thus supporting the concept of an antigen driven intermolecular epitope spreading to Ro/SS-A and dsDNA.
Beryllium-induced disturbances of the murine immune system reflect some phenomena observed in sarcoidosis.
1994
Sarcoidosis is a systemic granulomatous disorder of unknown origin. In respect to clinical and immunological characteristics, it is indistinguishable from berylliosis. As an approach to develop a murine model reflecting some aspects of sarcoidosis, we attempted to induce berylliosis in mice by treating inbred F1 mice (C57B16 x DBA/2) with 3 mg beryllium sulfate (BeSO4) per kg body weight intraperitoneally. Either pure BeSO4 or BeSO4 in combination with incomplete Freund's adjuvant was administered. Alternatively, pure BeSO4 was injected 2 days after a single application of cyclophosphamide (150 mg/kg). The spleen index, the spontaneous and phorbolmyristate acetate (PMA)-induced radical oxyg…
The Erythrocytic Hypothesis of Brain Energy Crisis in Sporadic Alzheimer Disease: Possible Consequences and Supporting Evidence
2020
Alzheimer’s disease (AD) is a fatal form of dementia of unknown etiology. Although amyloid plaque accumulation in the brain has been the subject of intensive research in disease pathogenesis and anti-amyloid drug development; the continued failures of the clinical trials suggest that amyloids are not a key cause of AD and new approaches to AD investigation and treatment are needed. We propose a new hypothesis of AD development based on metabolic abnormalities in circulating red blood cells (RBCs) that slow down oxygen release from RBCs into brain tissue which in turn leads to hypoxia-induced brain energy crisis; loss of neurons; and progressive atrophy preceding cognitive dysfunction. This …
S2k guideline for treatment of cutaneous lupus erythematosus - guided by the European Dermatology Forum (EDF) in cooperation with the European Academ…
2016
Cutaneous lupus erythematosus (CLE) is a rare inflammatory autoimmune disease with heterogeneous clinical manifestations. To date, no therapeutic agents have been licensed specifically for patients with this disease entity, and topical and systemic drugs are mostly used 'off-label'. The aim of the present guideline was to achieve a broad consensus on treatment strategies for patients with CLE by a European subcommittee, guided by the European Dermatology Forum (EDF) and supported by the European Academy of Dermatology and Venereology (EADV). In total, 16 European participants were included in this project and agreed on all recommendations. Topical corticosteroids remain the mainstay of trea…
MRT des Herzens bei Verdacht auf Myokarditis
2002
Purpose To evaluate the potential of ECG-gated breath-hold MRI in diagnosing acute myocarditis. Material and methods Cardiac MRI was performed on 21 consecutive patients with suspected myocarditis. ECG-gated breath-hold T2-weighted images with fat suppression were acquired in 3 standard views. T1-weighted imaging (FLASH) was performed 10 min after IV administration of Gd-DTPA. Laboratory data included creatine kinase, troponin T and serological tests, ECG findings and echocardiography. Imaging findings were retrospectively compared to the discharge diagnoses. Signal alterations were semiquantitatively classified. Results Acute myocarditis was diagnosed in 9 patients and cardiac sarcoidosis …
P609 New and old criteria for diagnosing celiac disease
2019
Background CD is an immune-mediated systemic disease elicited by gluten and related prolamines, it affects genetically susceptible individuals and it is characterized by the presence of gluten-dependent clinical manifestations, CD-specific antibodies, HLA-DQ2 or HLA-DQ8 haplotypes and enteropathy. According to the guidelines published by ESPGHAN in 2012, it is possible to diagnose celiac disease without intestinal biopsy, in symptomatic children and adolescents with very high levels of transglutaminases type-2 antibodies and positive HLA DQ2/DQ8. Aims The aim of our study is to analyse two groups of patients: one in which diagnosis was based on the new ESPGHAN criteria, and another based on…
How to manage patients with polyvascular atherosclerotic disease. Position paper of the International Union of Angiology
2020
Atherosclerosis is a systemic disease affecting multiple arterial territories. Patients with clinical atherosclerotic disease in one vascular bed are likely to have asymptomatic or symptomatic atherosclerotic lesions in other vascular beds. Specifically, peripheral arterial disease (PAD) often coexists with coronary and carotid disease. With progression of atherosclerotic disease in one vascular bed, the risk of clinical manifestations in other territories increases and the incidence of adverse cardiovascular events increases substantially with the number of affected vascular beds. Classical risk factors are associated with the development of polyvascular atherosclerotic disease (PVD) in di…
Challenges concerning argumentative writing in a second language context
2018
The current study is based on parts of the data collected in a quasi-experiment conducted in four English classes of Norwegian upper secondary school students. The purpose of the quasi-experiment was to explore whether a teaching intervention based on systemic functional linguistics and genre-pedagogy would support students in improving their competence in writing argumentative texts in English. The improvement was measured by comparing evaluations of pre-and post-tests. The current study investigates what seemed to be the main challenges for Norwegian students concerning this type of genre in a second language context based on the pre-tests and the evaluations of the pre-tests. The most ch…
