Abstract
This manuscript presents practical recommendations for managing acute attacks and implementing preventive immunotherapies for neuromyelitis optica spectrum disorders (NMOSD), a rare autoimmune disease that causes severe inflammation in the central nervous system (CNS), primarily affecting the optic nerves, spinal cord, and brainstem. The pillars of NMOSD therapy are attack treatment and attack prevention to minimize the accrual of neurological disability. Aquaporin-4 immunoglobulin G antibodies (AQP4-IgG) are a diagnostic marker of the disease and play a significant role in its pathogenicity. Recent advances in understanding NMOSD have led to the development of new therapies and the completion of randomized controlled trials. Four preventive immunotherapies have now been approved for AQP4-IgG-positive NMOSD in many regions of the world: eculizumab, ravulizumab - most recently-, inebilizumab, and satralizumab. These new drugs may potentially substitute rituximab and classical immunosuppressive therapies, which were as yet the mainstay of treatment for both, AQP4-IgG-positive and -negative NMOSD. Here, the Neuromyelitis Optica Study Group (NEMOS) provides an overview of the current state of knowledge on NMOSD treatments and offers statements and practical recommendations on the therapy management and use of all available immunotherapies for this disease. Unmet needs and AQP4-IgG-negative NMOSD are also discussed. The recommendations were developed using a Delphi-based consensus method among the core author group and at expert discussions at NEMOS meetings.

Abstract
The immune system plays a significant role in multiple sclerosis. While MS was historically thought to be T cell-mediated, multiple pieces of evidence now support the view that B cells are essential players in multiple sclerosis pathogenic processes. High-efficacy disease-modifying therapies that target the immune system have emerged over the past two decades. Anti-CD20 monoclonal antibodies selectively deplete CD20+ B and CD20+ T cells and efficiently suppress inflammatory disease activity. These monotherapies prevent relapses, reduce new or active magnetic resonance imaging brain lesions, and lessen disability progression in patients with relapsing multiple sclerosis. Rituximab, ocrelizumab, and ofatumumab are currently used in clinical practice, while phase III clinical trials for ublituximab have been recently completed. In this review, we compare the four anti-CD20 antibodies in terms of their mechanisms of action, routes of administration, immunological targets, and pharmacokinetic properties. A deeper understanding of the individual properties of these molecules in relation to their efficacy and safety profiles is critical for their use in clinical practice.

Late-onset neutropenia after anti-CD20 therapy for multiple sclerosis, neuromyelitis optica spectrum disorders and MOG antibody-associated disease: A prospective study. Rev Neurol (Paris) 2021; 178:253-255.

Abstract
Late-onset neutropenia (LON) after anti-CD20 therapy is a poorly described side effect in inflammatory disorders of the CNS. In this prospective study, patients treated with Rituximab or Ocrelizumab for MS, neuromyelitis optica spectrum disorders or MOG antibody-associated disease (MOGAD) were asked to perform complete blood count (CBC) every two weeks for six months, with the aim of identifying LON. Out of 152 patients, two (1,32%) had an absolute neutrophil count <1,000/mm3: one patient with MOGAD had agranulocytosis and one patient with MS had grade 3 neutropenia. Both were asymptomatic. These results confirm that LON after anti-CD20 therapy in inflammatory disorders of the CNS is not exceptional. Nevertheless, this biological complication remains too infrequent to justify close systematic CBC follow-up.

Abstract
INTRODUCTION Studies investigating rates and risk factors for serious safety events (SSEs) during rituximab treatment of multiple sclerosis (MS), neuromyelitis optica spectrum disorders (NMOSD), and related disorders are limited. METHODS Rituximab-treated patients with MS, NMOSD, or related disorders at the Rocky Mountain and New York University MS Care Centers were included. The follow-up period was defined as the time from the initial dose of rituximab up to 12 months of last dose of rituximab or ocrelizumab (in patients who switched). Clinician-reported and laboratory data were retrospectively collected from electronic medical records. RESULTS One-thousand patients were included comprising 907 MS, 77 NMOSD, and 16 related disorders. Patients had a mean follow-up of 31.1 months and a mean cumulative rituximab dose of 4012 mg. Of the 169 patients who switched to ocrelizumab, the mean ocrelizumab dose was 1141 mg. Crude incidence rate per 1000 person-years (PY) for lymphopenia was 19.2, neutropenia 5.6, and hypogammaglobulinemia 17.8. Infections resulting in either hospitalization, IV antibiotics, or using antibiotics ≥14 days occurred at a rate of 38.6/1000 PY. Risk factors for infection were duration of therapy, male gender, increased disability, prior exposure to immunosuppression/chemotherapy, lymphopenia, and hypogammaglobulinemia. Particularly, wheelchair-bound patients had 8.56-fold increased odds of infections. Crude incidence rates of malignant cancer were 3.5, new autoimmune disease 2.3, thromboembolic event 3.1, and mortality of 5.4 per 1000 PY. INTERPRETATION Rates of SSEs in patients with MS, NMOSD, and related disorders were low. Through properly assessing risk:benefit of B-cell depleting therapy in neuroinflammatory disorders and continual monitoring, clinicians may decrease the risk of serious infections.

Abstract
In recent years, there has been a paradigm shift in the treatment of multiple
sclerosis (MS) owing to the approval of a number of new drugs with very distinct
mechanisms of action. All approved disease-modifying drugs primarily work
directly on the immune system. However, the identification of an ‘optimal
choice’ for individual patients with regard to treatment efficacy, treatment
adherence and side-effect profile has become increasingly complex including
conceptual as well as practical considerations. Similarly, there are
peculiarities and specific requirements with regard to treatment monitoring,
especially in relation to immunosuppression, the development of secondary
immune-related complications, as well as the existence of drug-specific on- and
off-target effects. Both classical immunosuppression and selective immune
interventions generate a spectrum of potential therapy-related complications.
This article provides a comprehensive overview of available immunotherapeutics
for MS and their risks, detailing individual mechanisms of action and
side-effect profiles. Furthermore, practical recommendations for patients
treated with modern MS immunotherapeutics are provided.

Abstract
Rituximab is a widely used B-cell-depleting monoclonal antibody. It is unlicensed for use in neurological disorders and there are no treatment guidelines. However, as a rapidly acting, targeted therapy with growing evidence of efficacy and tolerability in several neuroinflammatory disorders, it is an attractive alternative to conventional immunomodulatory medications. This practical review aims to explain the basic principles of B-cell depletion with therapeutic monoclonal antibodies. We present the evidence for using rituximab in neurological diseases, and describe the practical aspects of prescribing, including dosing, monitoring, safety, treatment failure and its use in special circumstances such as coexisting viral hepatitis, pregnancy and lactation. We provide an administration guide, checklist and patient information leaflet, which can be adapted for local use. Finally, we review the safety data of rituximab and ocrelizumab (a newer and recently licensed B-cell-depleting therapy for multiple sclerosis) and suggest monitoring and risk reduction strategies.

Abstract
We present here the first MS-case where rituximab-treatment led to grade IV neutropenia, with hospitalization and treatment of a serious infection with broad-spectrum antibiotics. The neutropenia resolved promptly with granulocyte-colony stimulating factor-treatment and the patient recovered well. Due to risk of recurring neutropenia rituximab-treatment was not re-administered. We discuss the mechanisms and occurrence of neutropenia as a side effect to rituximab-treatment of MS, and remind of the importance of monitoring rituximab-treated MS-patients for this rare but potentially dangerous side effect.

Abstract
The effect of rituximab on primary central nervous system lymphoma (PCNSL) is controversial. We performed this meta-analysis to assess the efficacy of treatment with or without rituximab for PCNSL. We first conducted a search for qualified studies using PubMed, the Cochrane Library, and the Web of Science. The meta-analysis was conducted to compare odds ratios (ORs) with the corresponding 95% confidence interval (95% CI) for complete remission (CR) rate, progression-free survival (PFS), and overall survival (OS) using Review Manager 5.0. We included two randomized clinical trials and six retrospective studies in this meta-analysis. The results of our statistical analysis show that the use of rituximab was closely correlated with a higher CR (OR 1.70, 95% CI 1.17-2.46, P = 0.005), 2-year PFS (OR 2.11, 95% CI 1.08-4.11, P = 0.03), 5-year PFS (OR 2.54, 95% CI 1.64-3.93, P < 0.0001), 2-year OS (OR 2.40, 95% CI 1.73-3.34, P < 0.00001), and 5-year OS (OR 2.87, 95% CI 2.02-4.08, P < 0.00001). These results may help to inform therapeutic strategies including the use of rituximab and to improve therapeutic planning for PCNSL patients.

Abstract
Neuromyelitis optica spectrum disorders (NMOSD) are important evolving entities, which have reached much attention in the recent years. NMOSD are characterized by inflammatory lesions in the optic nerves, spinal cord, and central parts of the brain, as well as an autoimmune process directed against aquaporin-4. As disability in NMOSD accumulates by inflammatory damage from attacks, both the treatment and prevention of attacks are decisive for the long-term outcome. NMOSD attacks are treated with high-dose intravenous corticosteroids and apheresis therapies, in particular therapeutic plasma exchange. In cases of incomplete remission, escalation of attack treatment is recommended. Preventive therapy is immunosuppressive and should by commenced as early as possible. Apart from classical immunosuppressants such as azathioprine and mycophenolate mofetil, repurposed biologicals are increasingly used. B-cell depletion with rituximab and other agents, inhibition of the interleukin-6 receptor with tocilizumab, and blockade of complement-mediated damage by eculizumab all are promising therapeutic strategies evaluated in randomized controlled trials. In this review, we will discuss present and future immunotherapies for NMOSD and also consider combination of treatments, plasma, cellular and other therapies. Current advances in immunopathological knowledge are translated into innovative concepts and begin a new era of NMOSD therapy.

Abstract
The treatment of Burkitt's lymphoma with rituximab is controversial, and studies that compared the efficacy of chemotherapy alone with chemotherapy plus rituximab have not been powered to test differences in overall survival (OS). We conducted this systematic review and meta-analysis to identify the value of rituximab for the treatment of BL to guide treatment decisions. Based on the PubMed, Web of Science, and Cochrane library online electronic databases, all retrospective and randomized clinical trial studies that compared the aforementioned two regimens were included. The pooled hazard ratio and odds ratio were analyzed using Review Manager 5.3. The primary outcome was the 2-year OS. A total of 581 publications were identified using a predetermined search strategy. One randomized controlled trial (RCT) and five retrospective studies, which included 646 cases (351 cases for the chemotherapy with rituximab group and 295 cases for the chemotherapy alone group), fulfilled the selection criteria and were included in the meta-analysis. The chemotherapy with rituximab group was associated with a higher 2-year OS (hazard ratio 0.62, 95 % CI 0.45-0.85, P = 0.003), 2-year progression-free survival (hazard ratio 0.46, 95 % CI 0.43-0.50, P < 0. 001), and complete remission rate (odds ratios 3.26, 95 % CI 1.22-8.66, P = 0.02). In addition, the treatment-related mortality did not significantly differ between the two treatment regimens (odds ratio 1.16, 95 % CI 0.55-2.45, P = 0.69). The meta-analysis indicates that the addition of rituximab to the treatment regimen for Burkitt's lymphoma may be associated with a significant survival benefit and did not increase the mortality compared with chemotherapy alone.

Abstract
Neuromyelitis optica is a severe autoimmune condition affecting the central nervous system characterized by a relapsing disease course. Rituximab is a chimeric monoclonal antibody against the protein CD20, and is one of the most utilized medications for management of this disease. A known complication of rituximab use is neutropenia. We report on two patients who developed symptomatic early-onset rituximab-induced agranulocytosis who safely received granulocyte colony-stimulating factor. Neutrophil counts recovered quickly and both patients continue to receive rituximab without further incident.
