Several studies suggest that infection by EpsteinBarr virus (EBV) might be one of the environmental factors which facilitates the development of autoimmune disorders in genetically susceptible individuals. Recent data indicate that high anti-EpsteinBarr nuclear antigen 1 (EBNA)-1 immunoglobulin (Ig)G titre is a strong risk factor for multiple sclerosis (MS) in patients both with and without the main genetic predisposing trait, human leucocyte antigen (HLA)-DRB1*15:01. Because no similar studies have been published in systemic lupus erythematosus (SLE) patients, we determined the HLA-DRB1*15:01 carrier state and the serum titres against the whole EBNA-1 and its small fragments aa3558 and aa398404 in 301 SLE patients, 135MS patients and in 345 healthy controls. The carrier state of the HLA-DRB1*15:01 allele was deduced from genotyping of a tagSNP (rs3135388) by applying a Taqman-based assay. The serum concentrations of antibodies to EBNA-1 and its aa3558 or aa398404 fragments were determined using a commercial assay (ETI-EBNA-G) and home-made enzyme-linked immunosorbent assays, respectively. The serum concentration of anti-EBNA-1 antibodies was significantly (P<0 center dot 001) higher both in MS and SLE patients than in controls. Similar significant differences were found both in HLA-DRB1*15:01 carriers and non-carriers. Furthermore, titres of antibodies against the aa3558 EBNA-1 fragment were elevated both in MS and SLE patients. By contrast, the levels of aa398404 EBNA-1 antibodies were elevated significantly only in the SLE patients. These findings indicate that high anti-EBNA-1 IgG titres are HLA-DRB1*15:01-independent risk factors not only for MS, but also for SLE, while high antibody titres against the aa398404 fragment are characteristic for SLE.

Eculizumab use in a tertiary care nephrology center: data from the Vienna TMA cohort

Christof Aigner, Martina Gaggl, Gunar Stemer, Michael Eder, Georg Bohmig, Renate Kain, Zoltan Prohaszka, Nora Garam, Dorottya Csuka, Raute Sunder-Plassmann, Leah Charlotte Piggott, Natalja Haninger-Vacariu, Alice Schmidt, Gere Sunder-Plassmann

Summary: The study examined the indications and outcomes of eculizumab therapy in a tertiary care nephrology center, showing that it is the treatment of choice for patients with complement gene-variant mediated TMA who do not respond to plasma therapy. However, response rates to therapy were lower in patients with secondary TMA and C3 glomerulopathy, highlighting the importance of carefully considering the decision to start therapy.

Multiple sclerosis impairment scale and brain MRI in secondary progressive multiple sclerosis

Asta Theodorsdottir, Pia Veldt Larsen, Helle Hvilsted Nielsen, Zsolt Illes, Mads Henrik Ravnborg

Summary: In patients with secondary progressive MS (SPMS), the Multiple Sclerosis Impairment Scale (MSIS) correlated with functional motor tests. MSIS had stronger correlations with atrophy of central nervous system areas and may be more sensitive in assessing cerebellar and sensory function compared to the Expanded Disability Status Scale (EDSS).

Serum Level of Anti-Nucleocapsid, but Not Anti-Spike Antibody, Is Associated with Improvement of Long COVID Symptoms

Summary: This study found that antibody titers were associated with the severity of symptoms and remission status in long COVID patients. The immune response against SARS-CoV-2 nucleocapsid may play a more important role than the spike protein.

Summary: Neurosarcoidosis patients have significantly elevated levels of cytokines, chemokines, vascular angiogenesis, and vascular injury biomarkers in cerebrospinal fluid (CSF) and plasma.

MCPggaac haplotype is associated with poor graft survival in kidney transplant recipients with de novo thrombotic microangiopathy

Vojtech Petr, Dorottya Csuka, Petra Hruba, Agnes Szilagyi, Marek Kollar, Antonij Slavcev, Zoltan Prohaszka, Ondrej Viklicky

Summary: De novo thrombotic microangiopathy (TMA) is associated with poor kidney graft survival, and there is a recipient-driven process with suspected genetic background. Carriers of the MCPggaac haplotype have a higher risk of graft loss, and longer cold ischemia time is associated with worse graft survival.

Regaining Autonomy in a Holding Environment: Patients' Perspectives on the Existential Communication with Physicians When Suffering from a Severe, Chronic Illness: A Qualitative Nordic Study

Aida Hougaard Andersen, Zsolt Illes, Kirsten Kaya Roessler

Summary: This study investigates patients' experiences of existential communication with their physicians in the treatment of multiple sclerosis or chronic pain. Patients found it challenging when physicians focused only on medical aspects and neglected psychological and existential aspects of their illness. Patients needed a transition from dependency to autonomy for shared decision-making, and existential communication about transitional objects supported this transition.

Review and meta-analysis of neuropsychological findings in autoimmune limbic encephalitis with autoantibodies against LGI1, CASPR2, and GAD65 and their response to immunotherapy

Titulaer, Niels Hansen, Thorsten Bartsch, Andreas Johnen, Zslot Illes, Leah Borm, Alice G. Willison, Heinz Wiendl, Sven G. Meuth, Stjepana Kovac, Jens Boelte, Nico Melzer

Summary: This study aims to investigate whether autoimmune limbic encephalitis (ALE) with different associated autoantibodies (AABs) exhibit distinct neuropsychological manifestations and respond differently to immunotherapy. The results show that ALE patients with AABs against LGI1, CASPR2, and GAD65 commonly have memory deficits, along with deficits in attention, executive functions, and psychological function. However, there is currently no definite evidence supporting the notion that different AAB-types of ALE have distinct neuropsychological manifestations and respond differently to immunotherapy.

MAP-2:CD55 chimeric construct effectively modulates complement activation

Summary: The complement system is a complex cascade involved in pathogen defense and disease pathogenesis. Complement modulators, such as the fused MAP-2:CD55(1-4) inhibitor, show promising potential for treating complement-driven inflammatory diseases. This chimeric inhibitor effectively inhibits complement activation at multiple levels and demonstrates strong inhibitory activity in vitro.

Summary: This study developed and tested a reliable two-tier method using C1-INH and C4 quantitation followed by genetic analysis from dried blood spots (DBS) for diagnosing C1-INH-HAE. The quantification of C1-INH and C4 in DBS showed the same pattern as plasma, allowing for screening of patients with angioedema symptoms. DNA extracted from DBS is suitable for identifying various types of SERPING1 gene mutations.

Von Willebrand Factor and Platelet Levels before Conditioning Chemotherapy Indicate Bone Marrow Regeneration following Autologous Hematopoietic Stem Cell Transplantation

Zita Radnay, Arpad Illes, Miklos Udvardy, Zoltan Prohaszka, Gyorgy Sinkovits, Maria Csilla Csanyi, Miklos Kellermayer, Attila Kiss, Jolan Harsfalvi

Summary: This prospective observational study compares the changes in platelet count, VWF levels, ADAMTS13 activity, and CRP levels in lymphoma and multiple myeloma patients who underwent autologous hematopoietic stem cell transplantation (HSCT). The study explores the potential markers that vary in response to therapy, differ between the two groups, and correlate with the remission state at 100 days after HSCT. The results suggest that VWF and platelet count may have clinical significance in predicting the remission state after HSCT.
