Abstract
Background Neuromyelitis optica spectrum disorder (NMOSD) is a rare relapsing autoimmune disease of the central nervous system, affecting mainly optic nerves and spinal cord. NMOSD pathophysiology is associated with anti-aquaporin-4 (AQP4) immunoglobulin G (IgG) autoantibodies. Rapid extracorporeal elimination of autoantibodies with apheresis techniques, such as immunoadsorption (IA), was proven to be an effective treatment of NMOSD attacks. Data on the long-term use of IA to prevent attacks or progression of NMOSD are lacking. Objectives The aim of this study was to evaluate efficacy and safety of maintenance IA for preventing recurrence of NMOSD attacks in patients refractory to other immunotherapies. Design Case study. Methods Retrospective analysis of two female patients with severe NMOSD refractory to conventional immunotherapies was performed. Both patients had responded to tryptophan IA (Tr-IA) as attack therapy and subsequently were treated with biweekly maintenance Tr-IA. Results Patient 1 (AQP4-IgG seropositive, age 42 years) had 1.38 attacks of optic neuritis per year within 10.1 years before commencing regular Tr-IA. With maintenance Tr-IA for 3.1 years, one mild attack occurred, which was responsive to steroid pulse therapy. Expanded Disability Status Scale (EDSS) was stable at 5.0. Visual function score of the last eye improved from 3 to 1. Patient 2 (AQP4-IgG seronegative, age 43 years) experienced 1.7 attacks per year, mainly acute myelitis and optic neuritis, during the period of 10.0 years before the start of Tr-IA. During regular Tr-IA treatment, no further NMOSD attack occurred. The patient was clinically stable without any additional immunosuppressive treatment for 5.3 years. EDSS improved from 6.0 to 5.0, and the ambulation score from 7 to 1. Tolerability of Tr-IA was good in both patients. No serious adverse events occurred during long-term clinical trajectories. Conclusion Tr-IA was well tolerated as maintenance treatment and resulted in clinical stabilization of two patients with highly active NMOSD, who were refractory to standard drug therapy.

Immunoadsorption versus double-dose methylprednisolone in refractory multiple sclerosis relapses. J Neuroinflammation 2022; 19:220.

Abstract
Objective Intravenous methylprednisolone is the standard treatment for a multiple sclerosis relapse; however, this fails to improve symptoms in up to one quarter of patients. Immunoadsorption is an accepted treatment for refractory relapses, but prospective comparator-controlled studies are missing. Methods In this observational study, patients with steroid-refractory acute multiple sclerosis relapses receiving either six courses of tryptophan-immunoadsorption or double-dose methylprednisolone therapy were analysed. Outcomes were evaluated at discharge and three months later. Immune profiling of blood lymphocytes and proteomic analysis were performed by multi-parameter flow cytometry and Olink analysis, respectively (NCT04450030). Results 42 patients were enrolled (methylprednisolone: 26 patients; immunoadsorption: 16 patients). For determination of the primary outcome, treatment response was stratified according to relative function system score changes (“full/best” vs. “average” vs. “worse/none”). Upon discharge, the adjusted odds ratio for any treatment response (“full/best” + ”average” vs. “worse/none”) was 10.697 favouring immunoadsorption (p = 0.005 compared to methylprednisolone). At follow-up, the adjusted odds ratio for the best treatment response (“full/best” vs. “average” + ”worse/none”) was 103.236 favouring IA patients (p = 0.001 compared to methylprednisolone). Similar results were observed regarding evoked potentials and quality of life outcomes, as well as serum neurofilament light-chain levels. Flow cytometry revealed a profound reduction of B cell subsets following immunoadsorption, which was closely correlated to clinical outcomes, whereas methylprednisolone had a minimal effect on B cell populations. Immunoadsorption treatment skewed the blood cytokine network, reduced levels of B cell-related cytokines and reduced immunoglobulin levels as well as levels of certain coagulation factors. Interpretation Immunoadsorption demonstrated favourable outcomes compared to double-dose methylprednisolone. Outcome differences were significant at discharge and follow-up. Further analyses identified modulation of B cell function as a potential mechanism of action for immunoadsorption, as reduction of B cell subsets correlated with clinical improvement.

Abstract
BACKGROUND There are no systematic reviews yet that evaluated the effects of PE/IA in patients with optic neuritis (ON) in demyelinating diseases. A meta-analysis of available study is needed to further explore the value of plasma exchange (PE) or immunoadsorption (IA) in treating ON in demyelinating diseases. METHODS All relevant articles published on PubMed, Web of Science, Cochrane Library, Embase, China National Knowledge Infrastructure (CNKI), VIP Database, Wanfang, Sinomed and ophthalmology professional websites were searched. Study characteristics, demographic characteristics, clinical features and outcome measures were extracted. Response rate, adverse events (AE) rate, serious adverse event (SAE) rate, the log of the minimum angle of resolution (logMAR), visual outcome scale (VOS) and expanded disability status scales (EDSS) were evaluated using a random-effects model. RESULTS 35 studies were included between 1985 and 2020, containing 1191 patients. The response rates of PE and IA in acute attack of ON were 68% and 82% respectively. LogMAR (-0.60 to - 1.42) and VOS (-1.10 to -1.82) had been significantly improved from within 1 month to more than 1 month after PE treatment. Besides, we found that logMAR improved 1.78, 0.95 and 0.38, respectively ,when the time from symptom onset to the first PE/IA was less than 21 days, 21-28 days, and more than 28 days. The pooled mean difference of EDSS was -1.14.Adverse effects rate in patients with PE or IA were 0.20 and 0.06, respectively. CONCLUSION The meta-analysis provided evidence that PE/IA treatment was an effective and safe intervention, and it is recommended that early initiation of PE/IA treatment is critical.

Abstract
Multiple sclerosis (MS) is an inflammatory disease mainly affecting the central nervous system. In MS, abnormal immune mechanisms induce acute inflammation, demyelination, axonal loss, and the formation of central nervous system plaques. The long-term treatment involves options to modify the disease progression, whereas the treatment for the acute relapse has its focus in the administration of high-dose intravenous methylprednisolone (up to 1000 mg daily) over a period of three to five days as a first step. If symptoms of the acute relapse persist, it is defined as glucocorticosteroid-unresponsive, and immunomodulation by apheresis is recommended. However, several national and international guidelines have no uniform recommendations on using plasma exchange (PE) nor immunoadsorption (IA) in this case. A systematic review and meta-analysis was conducted, including observational studies or randomized controlled trials that investigated the effect of PE or IA on different courses of MS and neuromyelitis optica (NMO). One thousand, three hundred and eighty-three patients were included in the evaluation. Therapy response in relapsing-remitting MS and clinically isolated syndrome was 76.6% (95%CI 63.7–89.8%) in PE- and 80.6% (95%CI 69.3–91.8%) in IA-treated patients. Based on the recent literature, PE and IA may be considered as equal treatment possibilities in patients suffering from acute, glucocorticosteroid-unresponsive MS relapses.

Abstract
Introduction In acute inflammatory optic neuritis (ON) as a typical onset of multiple sclerosis (MS), only few studies have investigated plasma exchange (PLEX) as a sequential treatment after insufficient response to high-dose intravenous glucocorticosteroids. Therefore, we aimed to investigate treatment outcome on visual acuity (VA) with PLEX in patients with steroid-refractory ON. Methods In our retrospective monocentric study, medical records were screened for patients with acute ON as their first relapse with sequential MS diagnosis or with an established MS diagnosis from the Bern University Hospital (Switzerland) that were treated with PLEX between 2016 and 2018 due to lacking steroid response. VA prior to steroid administration, and before and after PLEX were assessed and compared using the Friedman multiple comparison test. Results In total, 18 patients were included in the analysis. Interval from symptom onset to PLEX was 20.3 days (mean, 95% CI 14.8-25.9). Relevant functional improvement (VA of ≥0.5, after a mean of 15.9 (13.3-18.5) days after start of PLEX) was detected in 16/18 (88.9%) with a significant amelioration as compared to VA before glucocorticosteroids and before PLEX (p < 0.0001). VA improvement at a later time point (38.1 weeks, 25.2-51.0) was present in 15/16 (93.8%) patients. No serious adverse events were detected. PLEX could be performed via peripheral access in 13/18 patients (72.2%). Conclusion Our study demonstrates significant improvements of VA with PLEX in a cohort of MS patients with steroid-refractory ON. High response rates may be due to the timely treatment initiation. Despite the small sample size, our data support the early use of PLEX in steroid-refractory ON with a favorable safety profile.

Abstract
The American Society for Apheresis (ASFA) Journal of Clinical Apheresis (JCA) Special Issue Writing Committee is charged with reviewing, updating and categorizing indications for the evidence-based use of therapeutic apheresis (TA) in human disease. Since the 2007 JCA Special Issue (Fourth Edition), the committee has incorporated systematic review and evidence-based approaches in the grading and categorization of apheresis indications. This Eighth Edition of the JCA Special Issue continues to maintain this methodology and rigor in order to make recommendations on the use of apheresis in a wide variety of diseases/conditions. The JCA Eighth Edition, like its predecessor, continues to apply the category and grading system definitions in fact sheets. The general layout and concept of a fact sheet that was introduced in the Fourth Edition, has largely been maintained in this edition. Each fact sheet succinctly summarizes the evidence for the use of TA in a specific disease entity or medical condition. The Eighth Edition comprises 84 fact sheets for relevant diseases and medical conditions, with 157 graded and categorized indications and/or TA modalities. The Eighth Edition of the JCA Special Issue seeks to continue to serve as a key resource that guides the utilization of TA in the treatment of human disease.

Safety and efficacy of immunoadsorption versus plasma exchange in steroid-refractory relapse of multiple sclerosis and clinically isolated syndrome: A randomised, parallel-group, controlled trial. EClinicalMedicine 2019; 16:98-106. [PMID: 31832624 PMCID: PMC6890948 DOI: 10.1016/j.eclinm.2019.10.017] [Citation(s) in RCA: 21] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/07/2019] [Revised: 10/21/2019] [Accepted: 10/28/2019] [Indexed: 12/18/2022] Open
Abstract
BACKGROUND Plasma exchange (PE) constitutes the standard therapy for steroid-refractory relapse in multiple sclerosis and clinically isolated syndrome. Immunoadsorption (IA) is an alternative method of apheresis which selectively removes immunoglobulines (Ig) while preserving other plasma proteins. Although IA is regarded as a well-tolerated, low-risk procedure, high-level evidence for its efficacy is lacking. Therefore, we sought to investigate whether IA is superior to PE in patients with acute relapse of multiple sclerosis or clinically isolated syndrome who had insufficiently responded to high-dose intravenous methylprednisolone (MP). METHODS Patients with acute relapse of multiple sclerosis or clinically isolated syndrome and without complete clinical remission of symptoms after at least one cycle of high-dose intravenous MP therapy were enrolled to our randomised, controlled, parallel-group, monocentric trial. Eligible patients were aged at least 12 years and had no clinical or laboratory signs of systemic infection. Eligible patients were randomly assigned (1:1) to receive either IA or PE. Patients in both groups received 5 treatments on 5 consecutive days. In the IA group, the 2.0-fold individual total plasma volume was processed on day 1, and the 2.5-fold on days 2-5. In the PE group, 2 liters of plasma (corresponding to the 0.69 ± 0.12-fold individual total plasma volume) were removed each day and substituted by 5% human albumin solution. Patients were followed up directly after last apheresis as well as 2 and 4 weeks after last treatment. The primary endpoint was change of the Multiple Sclerosis Functional Composite (MSFC) after 4 weeks compared to baseline. Analyses of primary outcome and safety measures were done in all patients who received at least one treatment (intention-to-treat-population). The trial is registered with ClinicalTrials.gov, number NCT02671682. FINDINGS Between January 21, 2016, and October 26, 2018, 63 patients were screened for eligibility, and 61 patients were randomly assigned to receive IA (n = 31) or PE (n = 30). All randomised patients were included in the intention-to-treat-analysis. For the primary outcome, the median improvement of MSFC after 4 weeks compared to baseline was 0.385 (IQR 0.200-0.675; p < 0.001) in the IA group and 0.265 (IQR 0.100-0.408; p < 0.001) in the PE group. Improvement in the IA group was significantly larger (p = 0.034) compared to PE. Response rates after 4 weeks were 86.7% in the IA group and 76.7% in the PE group. One deep venous thrombosis occurred in each group. INTERPRETATION Both IA and PE were safe in patients with steroid-refractory relapse and resulted in significant improvements of the primary outcome MSFC after 4 weeks compared to baseline. IA patients showed significantly larger improvements of MSFC compared to PE patients after 4 weeks. The results indicate a potential superiority of IA compared to PE in treatment of steroid-refractory relapse in multiple sclerosis and clinically isolated syndrome, which has to be confirmed by future studies.

Abstract
Multiple sclerosis (MS) is the most abundant inflammatory demyelinating disorder of the central nervous system. Despite recent advances in its long-term immunomodulatory treatment, MS patients still suffer from relapses, significantly contributing to disability accrual. In recent years, apheresis procedures such as therapeutic plasma exchange (TPE) and immunoadsorption (IA) have been recognized as two options for treating MS relapses, that do not respond to standard treatment with corticosteroids. TPE is already incorporated in most international guidelines, although evidence for its use resulted mostly from either case series or small unblinded and/or non-randomized trials. Data on IA are still sparse, but several studies indicate comparable efficacy between both apheresis procedures. This article gives an overview of the published evidence on TPE and IA in the treatment of acute relapses in MS. Further, we outline current evidence regarding individual outcome predictors, describe technical details of apheresis procedures, and discuss apheresis treatment in children and during pregnancy.

Abstract
Importance Plasma exchange and immunoadsorption are second-line apheresis therapies for patients experiencing multiple sclerosis relapses. Early active multiple sclerosis lesions can be classified into different histopathological patterns of demyelination. Pattern 1 and 2 lesions show T-cell- and macrophage-associated demyelination, and pattern 2 is selectively associated with immunoglobulin and complement deposits, suggesting a humoral immune response. Pattern 3 lesions show signs of oligodendrocyte degeneration. Thus it is possible that pathogenic heterogeneity might predict therapy response. Objective To evaluate the apheresis response in relation to histopathologically defined immunopathological patterns of multiple sclerosis. Design, Setting and Participants This single-center cohort study recruited 69 patients nationwide between 2005 and 2016. All included patients had a diagnosis of early active inflammatory demyelination consistent with multiple sclerosis; were classified into patterns 1, 2, or 3 based on brain biopsy analysis; and underwent apheresis treatments. Patients who had concomitant severe disease, neuromyelitis optica, or acute disseminated encephalomyelitis were excluded. Main Outcomes and Measures The primary therapy outcome was a functionally relevant improvement of the relapse-related neurological deficit. Radiological and Expanded Disability Status Scale changes were secondary outcome parameters. Results The mean (SD) age of patients was 36.6 (13.3) years; 46 of the 69 participants (67%) were female. Overall, 16 patients (23%) exhibited pattern 1 lesions, 40 (58%) had pattern 2 lesions, and 13 (19%) had pattern 3 lesions. A functional therapy response was observed in 5 of the 16 patients with pattern 1 disease (31%) and 22 of the 40 patients with pattern 2 disease (55%), but none of the 13 patients with pattern 3 disease exhibited improvement (pattern 2 vs 3 P < .001). Radiological improvements were found in 4 (25%), 22 (56%), and 1 (11%) of patients with patterns 1, 2, and 3, respectively. The respective rates of response measured by changes in Expanded Disability Status Scale scores were 25%, 40%, and 0%. Brainstem involvement was a negative predictive factor for the functional therapy response (logarithmic odds ratio [logOR], -1.43; 95% CI, -3.21 to 0.17; P = .03), while immunoadsorption (as compared with plasma exchange) might be a positive predictive factor (logOR, 3.26; 95% CI, 0.75 to 8.13; P = .01). Conclusions and Relevance This cohort study provides evidence that the response to apheresis treatment is associated with immunopathological patterns. Patients with both patterns 1 and 2 improved clinically after apheresis treatment, but pattern 2 patients who showed signs of a humoral immune response benefited most. Apheresis appears unlikely to benefit patients with pattern 3 lesions.

Abstract
Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system (CNS) in which the immune system damages the protective insulation surrounding the nerve fibers that project from neurons. A hallmark of MS and its animal model, experimental autoimmune encephalomyelitis (EAE), is autoimmunity against proteins of the myelin sheath. Most studies in this field have focused on the roles of CD4+ T lymphocytes, which form part of the adaptive immune system as both mediators and regulators in disease pathogenesis. Consequently, the treatments for MS often target the inflammatory CD4+ T-cell responses. However, many other lymphocyte subsets contribute to the pathophysiology of MS and EAE, and these subsets include CD8+ T cells and B cells of the adaptive immune system, lymphocytes of the innate immune system such as natural killer cells, and subsets of innate-like T and B lymphocytes such as γδ T cells, natural killer T cells, and mucosal-associated invariant T cells. Several of these lymphocyte subsets can act as mediators of CNS inflammation, whereas others exhibit immunoregulatory functions in disease. Importantly, the efficacy of some MS treatments might be mediated in part by effects on lymphocytes other than CD4+ T cells. Here we review the contributions of distinct subsets of lymphocytes on the pathogenesis of MS and EAE, with an emphasis on lymphocytes other than CD4+ T cells. A better understanding of the distinct lymphocyte subsets that contribute to the pathophysiology of MS and its experimental models will inform the development of novel therapeutic approaches.

Abstract
BACKGROUND Plasma exchange (PE) and immunoadsorption (IA) are alternative treatments of steroid-refractory relapses of multiple sclerosis (MS) or neuromyelitis optica (NMO). METHODS Adverse events and neurological follow-ups in 127 MS- (62 PE, 65 IA) and 13 NMO- (11 PE, 2 IA) patients were retrospectively analyzed. Response was defined by improvements in either expanded disability status scale (EDSS) by at least 1.0 or visual acuity (VA) to 0.5, confirmed after 3 and/or 6 months. RESULTS Hundred and forty patients were included in safety analysis, 102 patients provided sufficient neurological follow-up-data. There were no significant differences between IA and PE in side effects (3.9% vs 3.6%, P = .96) or response-rate (P = .65). Responders showed significant lower age (P = .02) and earlier apheresis-initiation (P = .01). Subgroup-analysis confirmed significant lower age in patients with relapsing-remitting MS (RRMS) /clinical isolated syndrome (CIS). CONCLUSION IA and PE seem equally safe and effective in steroid-resistant MS- or NMO-relapses. Early apheresis and low patient age are additional prognostic factors.

Abstract
While it was long held that T cells were the primary mediators of multiple sclerosis (MS) pathogenesis, the beneficial effects observed in response to treatment with Rituximab (RTX), a monoclonal antibody (mAb) targeting CD20, shed light on a key contributor to MS that had been previously underappreciated: B cells. This has been reaffirmed by results from clinical trials testing the efficacy of subsequently developed B cell-depleting mAbs targeting CD20 as well as studies revisiting the effects of previous disease-modifying therapies (DMTs) on B cell subsets thought to modulate disease severity. In this review, we summarize current knowledge regarding the complex roles of B cells in MS pathogenesis and current and potential future B cell-directed therapies.

Abstract
Multiple sclerosis (MS) is an autoimmune disorder where both T cells and B cells are implicated in pathology. However, it remains unclear how these two distinct populations cooperate to drive disease. There is ample evidence from studies in both MS patients and mouse models that Th17, B cells, and follicular T helper (TFH) cells contribute to disease. This review article describes the literature that identifies mechanisms by which Th17, TFH, and B cells cooperatively drive disease activity in MS and experimental autoimmune encephalomyelitis (EAE). The curation of this literature has identified that central nervous system (CNS) infiltrating TFH cells act with TH17 cell to contribute to an inflammatory B cell response in neuroinflammation. This demonstrates that TFH cells and their products are promising targets for therapies in MS.

Abstract
BACKGROUND Up to every fourth woman with multiple sclerosis (MS) or neuromyelitis optica spectrum disorder (NMOSD) suffers a clinically relevant relapse during pregnancy. High doses of steroids bear some serious risks, especially within the first trimester of pregnancy. Immunoadsorption (IA) is an effective and more selective treatment option in disabling MS relapse than plasma exchange. Data on the use of IA during pregnancy and breastfeeding are scarce. METHODS In this retrospective multicenter study, we analyzed the safety and efficacy of IA treatment in acute relapses during pregnancy or breastfeeding. The primary outcome parameter - change of acute relapse-related disability after IA - was assessed using Expanded Disability Status Scale (EDSS) and visual acuity (VA) measurements for patients with optic neuritis (ON). RESULTS A total of 24 patients were analyzed, 23 with relapsing-remitting MS, and 1 with NMOSD. Twenty patients were treated with IA during pregnancy. Four patients received IA postnatally during the breastfeeding period. Treatment was started at a mean 22.5 [standard deviation (SD) 13.9] days after onset of relapse. Patients were treated with a series of 5.8 (mean, SD 0.7) IA treatments within 7-10 days. Sixteen patients received IA because of steroid-refractory relapse, eight were treated without preceding steroid pulse therapy. EDSS improved clinically relevant from 3.5 [median, interquartile range (IQR) 2] before IA to 2.5 (median, IQR 1.1) after IA, p < 0.001. In patients with ON, VA improved in four out of five patients. Altogether, in 83% of patients, a rapid and marked improvement of relapse-related symptoms was observed after IA with either a decrease of ⩾1 EDSS grade or improvement in VA ⩾20%. No clinically relevant side effect was reported in 138 IA treatments. CONCLUSIONS Tryptophan-IA was found to be effective and well tolerated in MS/NMOSD relapses, both as an escalation option after insufficient response to steroid pulse therapy and as first-line relapse treatment during pregnancy and breastfeeding.

Abstract
PURPOSE To evaluate temporal changes in visual acuity in patients with steroid-resistant optic neuritis (ON) in neuromyelitis optica spectrum disorders (NMOSD) after apheresis. DESIGN Retrospective observational study, clinical case series SUBJECTS AND METHODS: We reviewed the medical charts of 15 eyes of 9 consecutive patients with ON in NMOSD who underwent apheresis between March 2010 and September 2017. All patients were seropositive for anti-aquaporin 4 (AQP4) antibody and resistant to steroid pulse therapy. Apheresis was performed by either simple plasma exchange or/and immune adsorption therapy. RESULTS Twelve eyes (80%) showed improvement with logMAR > 0.3 at 1 month after apheresis. Within 1 month after apheresis therapy, logMAR on average significantly decreased, the magnitude of change being greatest within the first week. Thereafter visual acuity became stable in 10 of the 11 eyes, until 12 months. However, two eyes (12%) showed recurrence of visual acuity reduction 3 months after the cessation of apheresis. There were a few serious complications during and after apheresis, but these were completely treatable. CONCLUSIONS Additional apheresis therapy rapidly improves the visual acuity of steroid-resistant seropositive AQP4 ON.

Abstract
The pathogenesis in the exacerbation of neuromyelitis optica spectrum disorder (NMOSD) involves mainly the serum anti-aquaporin-4 (AQP4) immunoglobulin G antibody (anti-AQP4 antibody). If high-dose corticosteroid treatment is not achieved during remission, rescue plasmapheresis is recommended. However, there are few reports on the therapeutic efficacy of repetitive immunoadsorption plasmapheresis (IAPP) for the recurrent exacerbation of NMOSD with a fluctuating anti-AQP4 antibody level. A 36-year-old man presented with a reduction of visual acuity (VA) on the right eye (OD) to 20/250. At this reduction of VA OD, magnetic resonance imaging (MRI) showed right optic nerve swelling without cerebral, brainstem, or spinal cord lesions. The anti-AQP4 antibody was detected in the serum. We diagnosed the patient with NMOSD and treated him with high-dose corticosteroid therapy. To prevent exacerbation with this treatment, the sixth session of the first IAPP course was adopted and VA OD improved to 20/100. Seven months later, VA OD deteriorated to 20/125 and ocular pain occurred. At that time, the anti-AQP4 antibody was not detected, although MRI revealed the recurrence of right optic neuritis. A second IAPP course with seven sessions was conducted with a concomitant administration of 1000 mg methylprednisolone every 10 days for 30 days. Ocular pain improved, although VA OD had continued to decline during these treatments and was eventually preserved at 20/400. In conclusion, IAPP is effective for the treatment of exacerbated NMOSD with a seropositive anti-AQP4 antibody. However, further study is necessary to develop treatments for relapsing NMOSD with a seronegative anti-AQP4 antibody.

The complex relationship between oligoclonal bands, lymphocytes in the cerebrospinal fluid, and immunoglobulin G antibodies in multiple sclerosis: Indication of serum contribution.

Abstract
Introduction Intrathecal immunoglobulin G (IgG) and oligoclonal bands (OCBs) are the most consistent and characteristic features of Multiple Sclerosis (MS). OCBs in MS are considered products of clonally expanded B cells in the cerebrospinal fluid (CSF), representing the sum of contributions from B cells in the brain. However, large amounts of IgG can be eluted from MS plaques in which lymphocytes are absent, and there is no correlation between levels of plaque-associated IgG and the presence of lymphocytes. It is calculated that it would take 3.2 billion lymphocytes to generate such large amounts of intrathecal IgG (30 mg in 500 ml CSF) in MS patients. Therefore, circulating lymphocytes in CSF could only account for <0.1% of the extra IgG in MS. Methods We analyzed clinical laboratory parameters from sera and CSF of 115 patients including 91 patients with MS and 24 patients with other inflammatory central nervous system (CNS) disorders (IC). We investigated the relationship between oligoclonal bands, IgG antibodies, CSF cells, IgG Index, albumin, and total protein. Results MS patients have significantly elevated serum concentrations of IgG antibodies, albumin, and total protein, lower levels of lymphocytes, albumin, and total protein in the cerebrospinal fluid, but no difference in CSF IgG concentration compared to those with other inflammatory neurological disorders. Furthermore, in MS there was no linear relationship between the numbers of OCBs, CSF lymphocytes, CSF IgG, and IgG Index, and between serum IgG and serum albumin, but significant correlation between IgG in CSF and serum, and between CSF IgG and CSF albumin. Conclusion There are unique differences between MS and patients with other inflammatory neurological disorders. Our data suggest that in MS patient (a) B cells and their products in the CSF may not be the sole source of intrathecal IgG; (b) oligoclonal bands may not be the products of single B cell clones in the CSF; and (c) there is a strong connection between serum components in the peripheral circulation and the central nervous system.

Abstract
Background In multiple sclerosis (MS), neurological disability results from incomplete remission of relapses and from relapse-independent progression. Intravenous high dose methylprednisolone (IVMP) is the established standard treatment to accelerate clinical relapse remission, although some patients do not respond. Most studies of relapse treatment have been performed when few patients received disease-modifying treatment and may no longer apply today. Methods We prospectively assessed, over one year, the course of patients who presented with a clinically isolated syndrome (CIS) or MS relapse, documenting demographic, clinical, treatment and outcome data. A standardized follow-up examination was performed 10–14 days after end of relapse treatment. Results We documented 119 relapses in 108 patients (31 CIS, 77 MS). 114 relapses were treated with IVMP resulting in full remission (29.2%), partial remission (38.7%), no change (18.2%) or worsening (4.4%). In 27 relapses (22.7%), escalating relapse treatment was indicated, and performed in 24, using double-dose IVMP (n = 18), plasmapheresis (n = 2) or immunoadsorption (n = 4). Conclusions Standardised follow-up visits and outcome documentation in treated relapses led to escalating relapse treatment in every fifth relapse. We recommend incorporating scheduled follow-up visits into routine relapse management. Our data facilitate the design of prospective trials addressing methods and timelines of relapse treatment.

Abstract
Therapeutic apheresis and immunoadsorption are used to deplete efficiently pathogenic autoantibodies in crises in several acute autoimmune driven diseases. This prospective, non-comparative cohort study was conducted at a single study center under standardized conditions in 10 healthy volunteers. Efficient immunoglobulin G (IgG) removal (-86% versus baseline) was achieved after 3 apheresis treatments on 3 consecutive days. The treatments were well tolerated. Safety laboratory parameters did not show unexpected or pathological changes. The effects were transient, with most parameters exhibiting complete recovery between treatments. Minimal complement activation and moderate transient fibrinogen depletion were observed. Immunoadsorption with LIGASORB® provides a safe and effective treatment alternative to TPE in acute episodes of peripheral neurological diseases mediated by pathogenic IgG autoantibodies.

Abstract
The role of B cells in the pathogenesis of Multiple Sclerosis (MS), an autoimmune neurodegenerative disease, is becoming eminent in recent years, but the specific contribution of the distinct B cell subsets remains to be elucidated. Several B cell subsets have shown regulatory, anti-inflammatory capacities in response to stimuli in vitro, as well as in the animal model of MS: Experimental Autoimmune Encephalomyelitis (EAE). However, the functional role of the B regulatory cells (Bregs) in vivo and specifically in the human disease is yet to be clarified. In the present review, we have summarized the updated information on the roles of effector and regulatory B cells in MS and the immune-modulatory effects of MS therapeutic agents on their phenotype and function.

Abstract
The American Society for Apheresis (ASFA) Journal of Clinical Apheresis (JCA) Special Issue Writing Committee is charged with reviewing, updating, and categorizing indications for the evidence-based use of therapeutic apheresis in human disease. Since the 2007 JCA Special Issue (Fourth Edition), the Committee has incorporated systematic review and evidence-based approaches in the grading and categorization of apheresis indications. This Seventh Edition of the JCA Special Issue continues to maintain this methodology and rigor to make recommendations on the use of apheresis in a wide variety of diseases/conditions. The JCA Seventh Edition, like its predecessor, has consistently applied the category and grading system definitions in the fact sheets. The general layout and concept of a fact sheet that was used since the fourth edition has largely been maintained in this edition. Each fact sheet succinctly summarizes the evidence for the use of therapeutic apheresis in a specific disease entity. The Seventh Edition discusses 87 fact sheets (14 new fact sheets since the Sixth Edition) for therapeutic apheresis diseases and medical conditions, with 179 indications, which are separately graded and categorized within the listed fact sheets. Several diseases that are Category IV which have been described in detail in previous editions and do not have significant new evidence since the last publication are summarized in a separate table. The Seventh Edition of the JCA Special Issue serves as a key resource that guides the utilization of therapeutic apheresis in the treatment of human disease. J. Clin.

Abstract
Optic neuritis (ON) is an acute inflammatory demyelinating disorder of the optic nerve. The general characteristics of isolated ON include unilateral, subacute, and painful visual loss without systemic or other neurological symptoms. The etiology for ON varies including demyelinating disorders or infections, inflammation, toxic reasons, and genetic disorders. In most cases the responsible etiology may not be known for ON and in this case, it is termed idiopathic ON. When a patient presents with an initial episode of ON, patients should undergo further tests. Assessing the patient with routine blood work, magnetic resonance imaging, cerebrospinal fluid tests, and visual evoked potentials provide further insight. In this review, we aimed to provide a review of ON as an initial symptom of multiple sclerosis and present clinical characteristics, therapy options, and recent literature.

Abstract
Patients suffering from multiple sclerosis (MS) are treated with high-dose intravenous steroids during acute relapses. In case of steroid refractory relapses, patients are treated with plasmapheresis or immunoadsorption. Until now data concerning the efficacy of both procedures are scarce. Visual evoked potentials (VEP), visual acuity and degree of remission of deficits caused by a relapse that had led to admission in MS patients (n = 48) treated with PLEX, IA or both in a single university centre setting were evaluated retrospectively. In a grouped analysis of patients treated with combined PLEX/IA, PLEX or IA alone, patients in all groups profited as assessed by VEP. Visual acuity also showed a trend towards a better performance, but lacked significance. In a subgroup analysis only concerning patients with initially pathological VEP there was a significant beneficial effect in the groups treated with PLEX/IA as well as in the group summarizing all patients. The combination of PLEX and IA provides a valid treatment option in steroid-refractory MS-relapses, and IA should be considered in acute relapses especially in patients with side effect of PLEX.

Abstract
In recent years, immunoadsorption is increasingly recognized as an alternative treatment approach replacing therapeutic plasma exchange in a variety of neurological disorders. While most experience is based on the application of single-use tryptophan adsorbers, less data exists on the application of more efficient regenerating adsorber columns. We here report the systematic use of a regenerating adsorber system in various neurological indications such as multiple sclerosis, encephalitis, myasthenia gravis and chronic inflammatory demyelinating polyneuropathy, providing the expected treatment success in regard to reduction of immunoglobulins and antibody clearance, together with a low rate of adverse events. As it has been shown for single-use columns before, immunoadsorption with regenerating adsorbers can be successfully applied in disorders without known specific antibodies such as multiple sclerosis. Regenerating systems offer the perspective to provide a more efficacious long term treatment perspective for such patients.

Abstract
Multiple sclerosis (MS) is a severe disease of the central nervous system (CNS) characterized by autoimmune inflammation and neurodegeneration. Historically, damage to the CNS was thought to be mediated predominantly by activated pro-inflammatory T cells. B cell involvement in the pathogenesis of MS was solely attributed to autoantibody production. The first clues for the involvement of antibody-independent B cell functions in MS pathology came from positive results in clinical trials of the B cell-depleting treatment rituximab in patients with relapsing-remitting (RR) MS. The survival of antibody-secreting plasma cells and decrease in T cell numbers indicated the importance of other B cell functions in MS such as antigen presentation, costimulation, and cytokine production. Rituximab provided us with an example of how clinical trials can lead to new research opportunities concerning B cell biology. Moreover, analysis of the antibody-independent B cell functions in MS has gained interest since these trials. Limited information is present on the effects of current immunomodulatory therapies on B cell functions, although effects of both first-line (interferon, glatiramer acetate, dimethyl fumarate, and teriflunomide), second-line (fingolimod, natalizumab), and even third-line (monoclonal antibody therapies) treatments on B cell subtype distribution, expression of functional surface markers, and secretion of different cytokines by B cells have been studied to some extent. In this review, we summarize the effects of different MS-related treatments on B cell functions that have been described up to now in order to find new research opportunities and contribute to the understanding of the pathogenesis of MS.

Abstract
BACKGROUND Approximately 25 % of women with multiple sclerosis (MS) suffer clinically relevant relapses during pregnancy. Almost all disease-modifying drugs are contraindicated in pregnancy. High-dose glucocorticoids have some serious risks, especially within the first trimester. Tryptophan immunoadsorption (IA) provides a safe option to treat MS relapses during pregnancy. OBJECTIVES In this case series we describe for the first time the use of tryptophan IA for MS and neuromyelitis optica (NMO) relapses during pregnancy and breastfeeding. PATIENTS AND METHODS In this study a total of 9 patients were retrospectively analyzed of which 7 patients received IA treatment during pregnancy, 2 during breastfeeding and 4-6 tryptophan IA treatments were performed per patient with the single use tryptophan adsorber. Primary outcome was symptom improvement of the relapse. RESULTS In this study four patients with MS and one with NMO relapse during pregnancy were treated with IA without preceding glucocorticoid pulse therapy. The MS patients showed improvement in the expanded disability status scale (EDSS) by at least one point, the NMO patient showed significant improvement in visual acuity and two pregnant patients with steroid-refractory relapses showed clinically relevant improvement after IA. Of the patients two suffered from steroid-refractory relapses during breastfeeding and relapse symptoms improved in both cases after treatment with IA. All treatments were well tolerated and no serious adverse events occurred. CONCLUSION Tryptophan IA was found to be safe, well-tolerated and effective in the treatment of MS and NMO relapses during pregnancy and breastfeeding, sometimes without preceding glucocorticoid pulse therapy. A binding recommendation is limited without prospective clinical studies.

Abstract
Alemtuzumab is the newest disease-modifying therapy approved for the treatment of relapsing multiple sclerosis. Alemtuzumab is an anti-CD52 targeted antibody that causes lysis of T and B lymphocytes, monocytes, natural killer cells, macrophages, and dendritic cells. Following its administration, a prolonged T-cell lymphopenia results with emergence of a reconstituted immune system that differs in its composition from that pretreatment. In clinical trials, alemtuzumab has shown impressive efficacy with regard to clinical and radiological outcomes in relapsing multiple sclerosis, along with sustained long-term beneficial effects, and it is attractive for its once-yearly administration. Despite this, the occurrence of serious secondary autoimmune disorders, infections, and a potential risk of malignancy necessitates a careful evaluation of risks versus benefits for an individual patient prior to its use. The requirement of patient commitment to the intense mandatory monitoring program is also a factor to be considered when incorporating alemtuzumab into the treatment regimen.

Abstract
AL (SpA A domain-PpL B3 domain), LD5 (PpL B3 domain-SpA D domain-PpL B3 domain-SpA D domain-PpL B3 domain, L-D-L-D-L) and LD3 (PpL B3 domain-SpA D domain-PpL B3 domain, L-D-L) are novel evolved Ig binding molecules (NEIBMs) derived from the in vitro molecular evolution of combinatorial phage libraries displaying randomly rearranged Ig-binding domains of protein A and protein L. These molecules all showed novel Ig-binding properties of double-site binding to the VH3 and Vκ regions of human Ig Fab and high affinity for human IgM, which enhanced IgM detection in the anti-HCV ELISA assay. In this double-site binding, the A domain binds to the VH3 chain with low affinity. Whether the appropriate mutations in the A domain could improve this binding remains unknown. In this study, four combinatorial phage libraries displaying AL mutants with random mutations at different amino acid positions in the A domain were constructed. Seven AL mutant phages with significantly improved Ig binding activity were obtained from the phage library displaying AL mutants randomly mutated at positions 27 and 34 through human IgM-directed in vitro evolution. Two of the seven prokaryotically expressed AL mutants, AL (VV) and AL (KA), exhibited IgM and IgG binding activities equivalent to those of wild-type AL, whereas other mutants showed attenuated binding. However, after labeling with HRP, AL (VV) and AL (KA) showed improved IgM and IgG binding activity, which significantly improved the detection in the anti-HCV assay. Thus, the present study demonstrates that the binding properties of AL were successfully improved through phage-based molecular evolution, which could substantially contribute to the use of AL in antibody detection, and provides an example of successful protein engineering through in vitro molecular evolution.

Abstract
AIM: To investigate the effect of nursing intervention using the plan-do-check-act (PDCA) cycle on the quality of life in patients with gastric ulcer.
METHODS: One hundred patients with gastric ulcer treated at our hospital from January 2012 to December 2013 were included and randomly divided into either a study group or a control group. The control group was given conventional nursing, while the study group received nursing intervention using the PDCA cycle. The patient's quality of life and satisfaction degree were compared between the two groups.
RESULTS: Before nursing care, the quality of life score did not differ significantly between the study group and control group (68.8 ± 4.2 vs 67.2 ± 4.8, P > 0.05). After nursing care, the quality of life score differed significantly between the study group and control group (87.5 ± 3.8 vs 76.2 ± 3.4, P < 0.05). The quality of life scores after nursing care in both group were significantly higher than those before nursing care (P < 0.05 for both). The rate of satisfaction to nursing was significantly higher in the study group than in the control group (94.0% vs 72.0%, P < 0.05).
CONCLUSION: Nursing intervention using the PDCA cycle in patients with gastric ulcer is feasible and can effectively improve the patient's quality of life and satisfaction.

Abstract
B linage cells are versatile players in multiple sclerosis (MS) and neuromyelitis optica/neuromyelitis optica spectrum disorder (NMO). New potential targets of autoantibodies have been described recently. Pathogenic mechanisms extend further to antigen presentation and cytokine production, which are increasingly recognized as therapeutic targets. In addition to pro-inflammatory effects of B cells, they may act also as anti-inflammatory via production of interleukin (IL)-10, IL-35, and other mechanisms. Definition of regulatory B cell subsets is an ongoing issue. Recent studies have provided evidence for a loss of B cell self-tolerance in MS. An immunogenetic approach demonstrated exchange of B cell clones between CSF and blood. The central nervous system (CNS) of MS patients fosters B cell survival, at least partly via BAFF and APRIL. The unexpected increase of relapses in a trial with a soluble BAFF/APRIL receptor (atacicept) suggests that this system is involved in MS, but with features that are not yet understood. In this review, we further discuss evidence for B cell and Ig contribution to human MS and NMO pathogenesis, pro-inflammatory and regulatory B cell effector functions, impaired B cell immune tolerance, the B cell-fostering microenvironment in the CNS, and B cell-targeted therapeutic interventions for MS and NMO, including CD20 depletion (rituximab, ocrelizumab, and ofatumumab), anti-IL6-R (tocilizumab), complement-blocking (eculizumab), inhibitors of AQP4-Ig binding (aquaporumab, small molecular compounds), and BAFF/BAFF-R-targeting agents.

Abstract
Neuromyelitis optica (NMO) is a severe inflammatory demyelinating disease with exacerbations involving recurrent or bilateral optic neuritis and longitudinally extensive transverse myelitis. Pulse steroid therapy is recommended as the initial, acute-phase treatment for NMO. If ineffective, treatment with plasma exchange (PE) should commence. However, no evidence exists to support the effectiveness of PE long after the acute phase. Immunoadsorption therapy (IA) eliminates pathogenic antibodies while sparing other plasma proteins. With IA, side effects of PE resulting from protein substitution can be avoided. However, whether IA is effective for NMO remains unclear. We describe a patient with anti-aquaporin-4-positive myelitis who responded to IA using a tryptophan polyvinyl alcohol gel column that was begun 52 days after disease onset following the acute phase. Even long after the acute phase when symptoms appear to be stable, IA may be effective and should not be excluded as a treatment choice.
