Abstract
As the role of neurologists in managing patients with rheumatic diseases expands, collaboration between rheumatologists and neurologists becomes increasingly vital. This literature review provides an overview of the central nervous system (CNS) manifestations of major autoimmune rheumatic disorders, which may include parenchymal brain and meningeal disease (stroke, meningoencephalitis, meningitis), myelopathies, psychosis, chorea, seizure disorders, and various forms of cephalea. Novel findings linking specific autoimmune markers to CNS damage reveal a direct, previously underestimated link between systemic inflammation and neural injury. Besides, with the increasing use of biological therapies, it is crucial to recognize when neurological manifestations are related to adverse events of therapy, as this may significantly influence treatment decisions. Neurologists play a key role in this assessment, working closely with rheumatologists. Overall, addressing CNS involvement in rheumatic diseases is important for improving patient outcomes and advancing medical knowledge in this complex field. A thorough understanding of the neurologic aspects of rheumatic diseases is essential for optimal patient care, necessitating a multidisciplinary approach to management.

Clinicopathologic characteristics of Nocardia brain abscesses: Necrotic and non-necrotic foci of various stages. J Neurol Sci 2024; 456:122850.

Abstract
Nocardia brain abscesses are rare bacterial infections associated with a high mortality rate, and their preoperative diagnosis can be difficult for various reasons including a nonspecific clinical presentation. While late-stage nocardial brain abscesses may be radiologically characteristic, early-stage lesions are nonspecific and indistinguishable from another inflammatory/infectious process and other mimics. Despite the paucity of previous histopathological descriptions, histopathological examination is critical for the identification of the pathogen, lesion stage(s), and possible coexisting pathology. In this study, we examined the clinical, radiological and histopathological features of 10 patients with brain nocardiosis. Microscopic findings were analysed in correlation with clinical and radiological features in 9 patients, which revealed that brain nocardiosis was characterized by numerous necrotic and non-necrotic foci of various stages (I-IV) along with Nocardia identification, as well as the leptomeningeal involvement in most cases, and co-infection of brain nocardiosis with toxoplasmosis in 2 patients. The imaging features were characteristic with a multilobulated/bilobed ring-enhancing appearance in 8 patients including 2 patients with multiple lobulated and non-lobulated lesions and 1 patient showing the progression from a non-lobulated to lobulated lesion. These findings suggest that nocardial brain abscesses particularly at late-stages share common characteristics. Nevertheless, given the complex pathologic features, including possible co-infection by other pathogens, nocardial brain abscesses remain a therapeutic challenge.

Progressive multifocal leukoencephalopathy in patients treated with rituximab: a 20-year review from the Southern Network on Adverse Reactions. LANCET HAEMATOLOGY 2021; 8:e593-e604. [PMID: 34329579 DOI: 10.1016/s2352-3026(21)00167-8] [Citation(s) in RCA: 25] [Impact Index Per Article: 8.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/03/2021] [Revised: 06/02/2021] [Accepted: 06/03/2021] [Indexed: 12/13/2022]
Abstract
Progressive multifocal leukoencephalopathy (PML) is a serious and usually fatal CNS infection caused by the John Cunningham virus. CD4+ and CD8+ T-cell lymphopenia, resulting from HIV infection, chemotherapy, or immunosuppressive therapy, are primary risk factors for PML. Following its introduction in 1997, the immunomodulatory anti-CD20 monoclonal antibody, rituximab, has received regulatory approval worldwide for treatment of non-Hodgkin lymphoma, rheumatoid arthritis, chronic lymphocytic leukaemia, granulomatosis with polyangiitis, microscopic polyangiitis, and pemphigus vulagris. Rituximab leads to prolonged B-lymphocyte depletion, potentially allowing John Cunningham viral infection to occur. Six unexpected cases of PML infection developing in rituximab-treated patients were first reported in 2002. We review 20 years of information on clinical findings, pathology, epidemiology, proposed pathogenesis, and risk-management issues associated with PML infection developing after rituximab treatment. Since the first case series report of 52 cases of rituximab-associated PML among patients with non-Hodgkin lymphoma or chronic lymphocytic leukaemia in 2009, updated and diligent pharmacovigilance efforts have provided reassurance that this fatal toxicity is a rare clinical event with concurring causal factors. International harmonisation of safety warnings around rituximab-associated PML should be considered, with these notifications listing rituximab-associated PML under a section titled warnings and precautions as is the case in most countries, rather than a boxed warning as is the case in the USA.

Abstract
Human polyomaviruses (HPyVs) encompass more than 10 species infecting 30%-90% of the human population without significant illness. Proven HPyV diseases with documented histopathology affect primarily immunocompromised hosts with manifestations in brain, skin and renourinary tract such as polyomavirus-associated nephropathy (PyVAN), polyomavirus-associated haemorrhagic cystitis (PyVHC), polyomavirus-associated urothelial cancer (PyVUC), progressive multifocal leukoencephalopathy (PML), Merkel cell carcinoma (MCC), Trichodysplasia spinulosa (TS) and pruritic hyperproliferative keratinopathy. Although virus-specific immune control is the eventual goal of therapy and lasting cure, antiviral treatments are urgently needed in order to reduce or prevent HPyV diseases and thereby bridging the time needed to establish virus-specific immunity. However, the small dsDNA genome of only 5 kb of the non-enveloped HPyVs only encodes 5-7 viral proteins. Thus, HPyV replication relies heavily on host cell factors, thereby limiting both, number and type of specific virus-encoded antiviral targets. Lack of cost-effective high-throughput screening systems and relevant small animal models complicates the preclinical development. Current clinical studies are limited by small case numbers, poorly efficacious compounds and absence of proper randomized trial design. Here, we review preclinical and clinical studies that evaluated small molecules with presumed antiviral activity against HPyVs and provide an outlook regarding potential new antiviral strategies.

Abstract
Purpose We performed a pharmacovigilance study of 10 drugs used in patients with relapsing-remitting multiple sclerosis (RR-MS). Our aim was to provide an overview of the safety of these drugs by the evaluation of reported expected and unexpected adverse reactions. Patients and methods We collected and analyzed adverse drug reactions from RR-MS patients belonging to four hospitals in three Italian regions, for a period of 24 months. Results We received a total of 411 adverse reactions, of which 84.18% were expected and only 15.82% were unexpected. We found no correlation between the number of reported adverse reactions and the route of administration (injectable/intravenous drugs N=224, oral drugs N=187). However, oral agents have caused a greater number of unexpected moderate-to-severe adverse reactions while, in injectable and infusion therapies, they have been evaluated as mild–moderate adverse reactions. Conclusion Our results underscore the importance of monitoring the safety profile of multiple sclerosis therapies, with particular attention to oral agents that have been introduced later in the clinical practice.

T cell deficiencies as a common risk factor for drug associated progressive multifocal leukoencephalopathy. Immunobiology 2018; 223:508-517.

Abstract
Progressive multifocal leukoencephalopathy (PML) is a disease of the central nervous system caused by neuropathogenic prototypes of ubiquitous community-acquired JC virus (JCV). The disease became of particular concern following its association with certain therapies that modulate immune system function without heavy immunosuppression. Due to lack of prophylactic/treatment options and poor outcomes, which often include severe disability or death, PML is a considerable concern for development of new drugs that interfere with immune system functions. In this review of clinical and research findings, we discuss the evidence that deficiencies in CD4+ T helper cells, cytotoxic CD8+ T cells, and interferon gamma are of crucial importance for development of PML under a variety of circumstances, including those associated with use of various drugs, regardless of differences in their mechanisms of action. These deficiencies apparently enable transformation of the harmless JCV archetype into neuropathogenic prototypes, but the site(s), and the mechanisms, of this transformation are yet to be elucidated. Here we discuss the evidence for brain as one of the sites of this transformation, and propose a model of PML pathogenesis that emphasizes the central role of T cell deficiencies in the two life cycles of the JCV, one non-pathogenic and one neuropathogenic. Finally, we conclude that the development of clinical grade T cell functional tests and more consistent use of already available laboratory tests for T cell subset analysis would greatly aid the effort to more accurately predict and assess the magnitude of PML risk for concerned therapeutic interventions.

Abstract
PURPOSE OF REVIEW There has been a considerable increase in the number of disease-modifying therapies (DMTs) in recent years. It appears that the number of approved DMTs is going to continue to increase in the coming years. The growing number of DMTs has provided a challenge to the clinician to tailor their therapeutic recommendations based on patients' needs and preferences. To choose between these DMTs, knowledge of side-effect profiles is imperative. RECENT FINDINGS Alemtuzumab, a humanized recombinant monoclonal antibody, was recently approved for the management of relapsing forms of multiple sclerosis. Its use seems to be limited by significant adverse effects and regular monitoring requirement. In 2014, the first case of progressive multifocal leukoencephalopathy (PML) was diagnosed in a patient with relapsing remitting multiple sclerosis who received extended dimethyl fumarate without any significant confounding factors. Among patients receiving fingolimod after previous natalizumab treatment, there have been 17 suspected cases of PML. There have also been three confirmed cases of PML in individuals who received fingolimod without previous natalizumab treatment. SUMMARY In this review, we outline the potential adverse effects and recommended laboratory studies as part of the monitoring strategy following initiation of various DMTs.

Abstract
A large number of viruses belonging to various families are able to cause central nervous system (CNS) infections and contribute significantly to burden of disease in humans globally. Most viral CNS infections are benign and self-limiting, and most remain undiagnosed. However, some viruses can cause severe inflammation, leading to morbidity and mortality, and result in severe long-term residual damage and neurologic dysfunction in patients. The potential of viruses to cause CNS inflammation greatly varies depending on host factors, such as age, sex, and genetic background, as well as viral factors. Despite the need for protection against viral invasion and replication, the extent of the immune response in the CNS is carefully regulated to prevent excessive inflammation and tissue destruction leading to irretrievable loss of neurons. Direct cytopathology is for many virus infections a major cause of neurologic symptoms; however, the antiviral immune response can in some instances contribute substantially to pathology. This chapter highlights a selection of clinically important neurotropic viruses that infect the CNS and cause neurologic diseases such as meningitis, encephalitis, and myelitis in humans, with a focus on neuropathologic findings.

Abstract
OBJECTIVE We described the clinical profile and outcomes of patients with SLE and RA diseases reported to the Brazilian Health Information System with primary dengue infection. METHODS Databases from the Brazilian Public Health Informatics System (SUS) were linked as the source of information. Three databases comprising different longitudinal information of lupus or rheumatoid arthritis (RA) patients under treatment and care through the Brazilian Health System were linked. Patients who had lupus ICD-9 code or RA ICD-9 code and their treatment approved by SUS were included in the study. In Study 1, we described the clinical characteristics of RA/lupus patients who had dengue infection. In Study 2, we compared RA/lupus patients with or without dengue for hospitalization rates after index dengue diagnosis for dengue-exposed or matching date for dengue-unexposed. RESULTS We included 69 SLE and 301 RA patients with dengue. In the RA/lupus with dengue case series, hospitalization was found in 24.6% of lupus subjects and of 11.2% of RA subjects. It differed by geographic region (p = 0.03), gender (p = 0.05) and the use of azathioprine (p = 0.02). Dengue was the most frequent reason for hospitalization reported (43.0%). Hospitalization due to dengue was noted in 12 (42.9%) dengue-exposed patients (p = 0.02), while rheumatoid arthritis was reported as the cause of hospitalization in 22.2% of dengue-unexposed (p = 0.005). Five deaths were reported among the dengue-exposed and none among dengue-unexposed. Bacterial infection was the most frequent cause of death. We found that the dengue exposure was associated with an increased risk of hospitalization outcome in RA and lupus patients (RR = 6.2; 95% CI: 2.99-12.94). SUMMARY We found that when comparing RA/lupus patients with or without dengue, dengue-exposed patients had an increased rates of hospitalization and death.

Abstract
Opportunistic infections can cause manifestations that resemble neuropsychiatric systemic lupus erythematosus and they can also trigger lupus flares. Therefore, central nervous system infections as differential diagnosis in neuropsychiatric systemic lupus erythematosus may be difficult, leading to delayed diagnosis and specific treatment. Central nervous system infection in systemic lupus erythematosus is not common but, if left misdiagnosed and not treated promptly, can be fatal. Complementary diagnosis tests are generally non-specific and disappointing. Caution with immunosuppressive drug treatment should be emphasized while an opportunistic infection cannot be ruled out. In this review, we discuss the various types of central nervous system infections reported in systemic lupus erythematosus patients, highlighting the importance of their early recognition in order to improve morbidity and mortality. Prevention with vaccination is a recommended approach.

Abstract
PURPOSE OF REVIEW Multiple sclerosis (MS) is an autoimmune demyelinating disease of the central nervous system most often characterized by clinical relapses and periods of remission. RECENT FINDINGS The past decade has seen a dramatic increase in disease-modifying therapies for MS. Fourteen FDA-approved immunomodulatory drugs are currently available, and more medications are in development. A growing number of reported opportunistic infections, including progressive multifocal leukoencephalopathy (PML), highlight the serious complications of these new drugs and the need for specific screening guidelines. Using data from Phase II and III randomized controlled trials, case reports, drug manufacturing data, and clinical experience, we outline the most common and serious infections associated with novel MS therapies.

Abstract
Multiple sclerosis (MS) is an autoimmune, demyelinating disease of the central nervous system (CNS). It predominantly affects young women and is one of the most common causes of disability in young adults. MS is characterized by formation of white matter lesions in the CNS as a result of inflammation, demyelination, and axonal loss. Treatment has been a focus of neurological research for over 60 years. A number of disease-modifying therapies (DMTs) have become available making MS a treatable disease. These compounds target the inflammatory response in MS. They work by decreasing the chances of relapse, decreasing the chances of new lesion formation seen on MRI of the CNS and slowing the accumulation of disability. The first drugs for MS to be available were interferon-β and glatiramer acetate. These work by modulating the inflammatory response via different mechanisms that are briefly discussed. Newer agents have since become available and have significantly changed the dynamics of MS treatment. These include fingolimod, dimethyl fumarate and teriflunomide, which are oral agents. Other second-line and third-line Food and Drug Administration (FDA) approved medications include natalizumab and alemtuzumab. Natalizumab is considered one of the most potent treatments for relapse prevention. However, the high risk of progressive multifocal leukoencephalopathy (PML), which is caused by JC virus infection in the brain, tempers the more widespread use of this agent; nevertheless, JC virus antibody tests have helped to stratify the risk of PML. Alemtuzumab, which also has a considerable side effect profile, is likewise highly efficacious. Ocrelizumab, a monoclonal antibody to CD20 on B cells, is a highly effective agent for MS that is likely to be approved soon by the FDA. MS is a major contributor to healthcare costs and it is critical that healthcare providers be aware of the availability and benefits of DMTs. It is imperative that prompt and adequate treatment be established on diagnosis. Changes in therapy should be considered when there is evidence of disease activity as well as accumulation of disability or safety or tolerability concerns.

Today, orally available second generation immunosuppressive agents have been approved or are filed for licensing as MS therapeutics. Due to semi-selective targeting of cellular processes, these second-generation immunosuppressive compounds might rather be immunomodulatory. For example, Teriflunomide inhibits the de novo pyrimidine synthesis and thus only targets rapidly proliferating cells, including lymphocytes. It is used as first line disease modifying therapy (DMT) in relapsing-remitting MS (RRMS). METHODS Review of online content related to oral immunosuppressants in MS with an emphasis on Teriflunomide. RESULTS Teriflunomide and Cladribine are second-generation immunosuppressants that are efficient in the treatment of MS patients. For Teriflunomide, a daily dose of 14 mg reduces the annualized relapse rate (ARR) by more than 30% and disability progression by 30% compared to placebo. Cladribine reduces the ARR by about 50% compared to placebo but has not yet been licensed due to unresolved safety concerns. We also discuss the significance of older immunosuppressive compounds including Azathioprine, Mycophenolate mofetile, and Cyclophosphamide in current MS therapy. CONCLUSION Teriflunomide has shown a favorable safety and efficacy profile in RRMS and is a therapeutic option for a distinct group of adult patients with RRMS.

Drug-associated progressive multifocal leukoencephalopathy: a clinical, radiological, and cerebrospinal fluid analysis of 326 cases. J Neurol 2016; 263:2004-21. [PMID: 27401179 PMCID: PMC5037162 DOI: 10.1007/s00415-016-8217-x] [Citation(s) in RCA: 48] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2016] [Revised: 06/22/2016] [Accepted: 06/23/2016] [Indexed: 02/07/2023]
Abstract
The implementation of a variety of immunosuppressive therapies has made drug-associated progressive multifocal leukoencephalopathy (PML) an increasingly prevalent clinical entity. The purpose of this study was to investigate its diagnostic characteristics and to determine whether differences herein exist between the multiple sclerosis (MS), neoplasm, post-transplantation, and autoimmune disease subgroups. Reports of possible, probable, and definite PML according to the current diagnostic criteria were obtained by a systematic search of PubMed and the Dutch pharmacovigilance database. Demographic, epidemiologic, clinical, radiological, cerebrospinal fluid (CSF), and histopathological features were extracted from each report and differences were compared between the disease categories. In the 326 identified reports, PML onset occurred on average 29.5 months after drug introduction, varying from 14.2 to 37.8 months in the neoplasm and MS subgroups, respectively. The most common overall symptoms were motor weakness (48.6 %), cognitive deficits (43.2 %), dysarthria (26.3 %), and ataxia (24.1 %). The former two also constituted the most prevalent manifestations in each subgroup. Lesions were more often localized supratentorially (87.7 %) than infratentorially (27.4 %), especially in the frontal (64.1 %) and parietal lobes (46.6 %), and revealed enhancement in 27.6 % of cases, particularly in the MS (42.9 %) subgroup. Positive JC virus results in the first CSF sample were obtained in 63.5 %, while conversion after one or more negative outcomes occurred in 13.7 % of cases. 52.2 % of patients died, ranging from 12.0 to 83.3 % in the MS and neoplasm subgroups, respectively. In conclusion, despite the heterogeneous nature of the underlying diseases, motor weakness and cognitive changes were the two most common manifestations of drug-associated PML in all subgroups. The frontal and parietal lobes invariably constituted the predilection sites of drug-related PML lesions.

Abstract
Management of central nervous system (CNS) involvement still remains one of the most challenging problems in systemic lupus erythematosus (SLE). The best available evidence for the treatment of CNS lupus is largely based on retrospectiveseries, case reports and expert opinion. Current therapy is empirical and tailored to the individual patient. Symptomatic, immunosuppressiveand anticoagulant therapies are the main strategies for the management of CNS lupus. The choice depends on the most probable underlying pathogenic mechanism and the severity of the presenting neuropsychiatric symptoms. Thrombotic and nonthrombotic CNS disease needs to be differentiated and requires different management strategies. However, this is often challenging since many, if not most CNS manifestations, may be due to a combination of different pathogenic mechanisms and multiple CNS events may occur in the individual patient. Patients with mild manifestations may need symptomatic treatment only, whereas more severe acute nonthrombotic CNS manifestations may require pulse intravenouscyclophosphamide.Plasmapheresismay also be added in patients with more severe illness refractory to conventionaltreatment. Recently, the use of intrathecalmethotrexateand dexamethasone has been reported in a small series of patients, with a good outcome in patients with severe CNS manifestations.Anticoagulationis warranted in patients with thrombotic disease, particularlyin those with the antiphospholipid syndrome (APS). This article reviews the clinical approach to therapy in patients with CNS lupus.

Abstract
We report magnetic resonance imaging findings of 4 patients with systemic lupus erythematosus who presented with noninfectious meningitis by lupus itself. Magnetic resonance imaging of the brain demonstrated diffuse or localized high-signal intensity in subarachnoid spaces on fluid-attenuated inversion recovery (FLAIR) or postcontrast fluid-attenuated inversion recovery. Cerebrospinal fluid study revealed no abnormalities other than increased level of proteins. Our report is the first description of magnetic resonance findings in context of leptomeningeal involvement in non-infectious meningitis of patients with systemic lupus erythematosus.

Abstract
PURPOSE OF REVIEW The purpose of this review is to summarize mechanisms of action, efficacy and safety of established disease-modifying treatments (DMTs) that have been widely approved for use in relapsing-remitting multiple sclerosis (RRMS). RECENT FINDINGS Established and widely used DMTs for the treatment of RRMS include the interferon-β agents, glatiramer acetate, natalizumab, fingolimod, teriflunomide and dimethyl fumarate. These DMTs have quite different mechanisms of action, efficacy and safety and tolerability profiles, which are summarized concisely in the article below. SUMMARY The treatment algorithm for RRMS is becoming increasingly complex with the ever-expanding armamentarium of DMTs. The choice of DMT will become an increasingly individual decision, based on a number of factors, including disease activity and severity, safety/tolerability profile and patient preference. Neurologists treating patients with multiple sclerosis (MS) will need a thorough knowledge of efficacy, safety and tolerability of the spectrum of DMTs available for treatment of RRMS to provide comprehensive clinical care.

Abstract
OBJECTIVE To determine risk factors for progressive multifocal leukoencephalopathy (PML) in systemic lupus erythematosus (SLE) patients, and understand how underlying disease or treatment for SLE may be associated with PML in this population. METHODS Studies published in English between January 1, 1984 and October 31, 2014 that reported PML in adult SLE patients were included. Immunosuppression was defined as exposure to ≥1 immunosuppressant drug of interest at PML diagnosis: belimumab, rituximab, mycophenolate mofetil, azathioprine, cyclophosphamide, methotrexate and high-dose corticosteroids (>15 mg/day). Minimal immunosuppression was defined as low-dose corticosteroids (≤15 mg/day) and/or anti-malarials. RESULTS Thirty-five publications met our inclusion criteria: four observational studies, two large case series, and 29 case reports that described 35 cases. Reported PML incidence rates among SLE patients based on observational studies ranged from 1.0 to 2.4 cases/100,000 person-years. Of the 35 case reports, three cases were exposed to no immunosuppressant drugs at PML diagnosis, five cases had minimal immunosuppression, 23 cases had immunosuppression, and four cases were indeterminate. CONCLUSIONS The evidence from this literature review suggests that, while PML is a very rare disease in SLE patients, there does appear to be an increased risk of PML associated with SLE compared to the general population, potentially due to immunosuppression, other contributing factors in their underlying disease, treatments prescribed to manage disease, or some combination of these factors. Additional large observational studies, designed to assess exposure to drugs of interest and complicated treatment histories, are needed to provide further evidence about potential mechanisms contributing to the onset of PML in SLE patients.

Abstract
Treatment options in relapsing-remitting multiple sclerosis have increased considerably in recent years; currently, a dozen different preparations of disease-modifying therapies are available and some more are expected to be marketed soon. For the treating neurologist this broad therapeutic repertoire not only greatly improves individualized management of the disease, but also makes choices more complex and difficult. A number of factors must be considered, including disease activity and severity, safety profile, and patient preference. We here discuss the currently existing options and suggest treatment algorithms for managing relapsing-remitting multiple sclerosis.

Abstract
The interface of multiple sclerosis (MS) and infection occurs on several levels. First, infectious disease has been postulated as a potential trigger, if not cause, of MS. Second, exacerbation of MS has been well-documented as a consequence of infection, and, lastly, infectious diseases have been recognized as a complication of the therapies currently employed in the treatment of MS. MS is a disease in which immune dysregulation is a key component. Examination of central nervous system (CNS) tissue of people affected by MS demonstrates immune cell infiltration, activation and inflammation. Therapies that alter the immune response have demonstrated efficacy in reducing relapse rates and evidence of brain inflammation on magnetic resonance imaging (MRI). Despite the altered immune response in MS, there is a lack of evidence that these patients are at increased risk of infectious disease in the absence of treatment or debility. Links between infections and disease-modifying therapies (DMTs) used in MS will be discussed in this review, as well as estimates of occurrence and ways to potentially minimize these risks. We address infection in MS in a comprehensive fashion, including (1) the impact of infections on relapse rates in patients with MS; (2) a review of available infection data from pivotal trials and postmarketing studies for the approved and experimental DMTs, including frequency, types and severity of infections; and (3) relevant risk minimization strategies, particularly as they pertain to progressive multifocal leukoencephalopathy (PML).

Abstract
The objective of this study is to identify the clinical differences between infectious meningitis and neuropsychiatric systemic lupus erythematosus (NPSLE) in patients with SLE. Clinical manifestations, laboratory test results, and prognoses of 14 SLE patients complicated with various infectious meningitis, hospitalized in the Affiliated Drum Tower Hospital of Nanjing University Medical School in the past 7 years, were reviewed and compared with those of 34 concomitantly treated NPSLE patients. Our study shows that mortality rate was much higher in SLE patients with infectious meningitis than in NPSLE patients. Compared to NPSLE, those with infectious meningitis had lower SLE Disease Activity Index (SLEDAI), but higher doses of corticosteroids 1 month before the occurrence of CNS symptoms. Headache, high fever, and vomiting were more common in patients with infectious meningitis, accompanied with the elevation of C-reactive protein level. Cerebrospinal fluid (CSF) examination showed increased levels of leukocytes and proteins but decreased glucose level in patients with infectious meningitis. We conclude that for SLE patients exhibiting CNS symptoms, high fever, high intake of corticosteroids, and abnormal CSF are important clues for the coexistence of infectious meningitis, especially tuberculous meningitis.

Abstract
Over the past two decades, major advances have been made in the development of disease-modifying agents (DMAs) for multiple sclerosis (MS), and nine agents are now licensed for use in the treatment of MS in the United States. Clinical trials have demonstrated that a number of investigational agents have beneficial effects on clinical and radiographic measures of disease activity, thus the repertoire of available DMAs in MS will likely continue to expand moving forward. Although many of the first-line DMAs have the benefits of established long-term safety and tolerability, in some patients, treatment with one of the more potent novel agents may be appropriate. However, the use of novel agents must be approached with caution, since short-term clinical trials give little information on the long-term efficacy and safety of novel DMAs in MS patients. This chapter will consider the efficacy and safety of both established and investigational agents for the treatment of MS.

Abstract
Wegener's granulomatosis (WG) is a systemic vasculitis affecting small and medium-sized vessels with granulomatous formation. Though it is known for respiratory tract and kidney involvement, neurologic manifestation has been also reported. Herein we report a patient who suffered pansinusitis with multiple lower cranial nerve palsies but reached remission by immunosuppressant after the diagnosis of WG. A 54-yr-old female visited with headache, hearing difficulty, and progressive bulbar symptoms. She experienced endoscopic sinus surgeries due to refractory sinusitis. Neurologic examination revealed multiple lower cranial nerve palsies. Vasculitic markers showed no abnormality. Nasal biopsy revealed granulomatous inflammation and vasculitis involving small vessels. Given cyclophosphamide and prednisolone, her symptoms were prominently improved. WG should be considered in the patient with multiple cranial nerve palsies, especially those with paranasal sinus disease. Because WG can be lethal if delayed in treatment, prompt immunosuppressant is warranted after the diagnostic tissue biopsy.

Although Nocardiosis has considerable recurrence and mortality rates, characteristics and risk factors of Nocardia infection have not been assessed in patients with rheumatic diseases. Here, we examined the characteristics and risk factors of Nocardia infection in rheumatic disease patients in our hospital. Ten rheumatic disease patients who developed Nocardia infection were identified by retrospectively reviewing the medical records. Possible predisposing factors for Nocardia infection were high-dose glucocorticoid treatment, concomitant use of immunosuppressants, preexisting pulmonary diseases, and diabetes mellitus. All patients had pulmonary Nocardiosis, and six of them had disseminated Nocardiosis when their pulmonary lesions were identified.

Abstract
Treatment options for relapsing-remitting multiple sclerosis (RRMS) have been continuously expanding in recent years, and the emergence of a number of oral disease-modifying agents (DMAs) has significantly changed the landscape of therapeutic options for MS patients. Many of these oral DMAs have demonstrated satisfactory safety and tolerability profiles in clinical trial settings, but the long-term safety of these agents is an important concern. This review discusses salient points on the safety and clinical efficacy of the approved and emerging novel oral therapies in RRMS, including fingolimod, teriflunomide, dimethyl fumarate, laquinimod, and cladribine.

Abstract
Teriflunomide is a novel disease-modifying agent that was recently approved for use in the treatment of multiple sclerosis (MS). Teriflunomide has demonstrated clinical efficacy and safety in a number of large, multicenter, phase III clinical trials and is an attractive agent to add to the growing repertoire of available treatments for MS, as it has the benefit of oral administration. Furthermore, existing clinical experience with its parent drug, leflunomide, provides indirect long-term safety data. This review summarizes teriflunomide's pharmacologic properties, pivotal clinical trials, and safety profile, and ends with a discussion of the role of teriflunomide in the context of current and emerging MS treatment options.

Teriflunomide, the active metabolite of an approved antirheumatic drug, is an emerging oral therapy for multiple sclerosis (MS). Next to the inhibition of pyrimidine biosynthesis and proliferation of activated lymphocytes, it seems to have multiple anti-inflammatory and immunomodulating effects. Phase II and III clinical trials in relapsing MS demonstrated favorable safety and tolerability of the drug, as well as clinical efficacy, with a significant reduction of relapse rate, comparable with those of the available injectable immunomodulatory agents. While multiple other studies with teriflunomide are currently ongoing, its exact place in future treatment algorithms for MS is difficult to predict. It may be a good alternative for patients wishing to have an oral treatment with relatively large data regarding long-term safety.

Abstract
There are a number of oral agents emerging as potential disease-modifying agents in multiple sclerosis (MS). Among these investigational agents, teriflunomide has shown promise in large, multicenter, phase III clinical trials with respect to safety and efficacy in relapsing MS patients, and is the latest disease-modifying agent approved for use in MS patients in the United States. This review will summarize teriflunomide’s historical development, clinical pharmacology, studies in animals, clinical trials, and safety data, and will end with a discussion of the role of teriflunomide in MS in the context of existing treatment options.

Abstract
Progress in the diagnosis and management of pediatric rheumatic disease has improved complications from underlying disease and the survival of children. However, as a consequence, infection has now become one of the leading causes of morbidity and mortality. Differentiating between infections and disease flares in children with rheumatic conditions can often pose diagnostic quandaries. Children with rheumatic diseases are at risk of infection, not only because of the use of immune-modulating medications but also because of underlying immune dysfunction associated with their disease. Although bacterial infections are the most common, any organism can potentially be a causative agent and, at times, more invasive measures of diagnosis, for example bronchoscopy and tissue biopsies may be necessary. Maintaining a high index of suspicion of infection with prompt diagnosis and treatment are important to further improve patient outcomes.

Abstract
Treatment for multiple sclerosis (MS), a chronic disease of the central nervous system, has historically relied exclusively on the use of injectable therapies. As the disease requires lifelong therapy, the development of oral therapies that are safe and effective would provide a more convenient dosage form that may improve patient compliance. One oral medication (fingolimod) was recently approved for treatment of MS. Teriflunomide, an immunomodulator, is one of four oral therapies currently undergoing Phase III trials. Teriflunomide exerts its clinical effects via selective inhibition of de novo pyrimidine synthesis, primarily targeting proliferating T and B lymphocytes in the periphery. Teriflunomide was effective as monotherapy in reducing magnetic resonance imaging lesions and annual relapse rates in Phase II and Phase III trials. When teriflunomide was added to interferon or glatiramer acetate therapy in Phase II trials, teriflunomide reduced magnetic resonance imaging lesions significantly more than either interferon or glatiramer acetate alone. Treatment-emergent adverse events occurred at similar rates among all groups in teriflunomide studies, with a trend towards a higher treatment emergent adverse events rate in the higher dosage group of teriflunomide (14 mg daily). Treatment discontinuations in teriflunomide trials were relatively low, suggesting that teriflunomide monotherapy is well tolerated. This article reviews the mode of action of teriflunomide, its pharmacokinetic, clinical efficacy, and safety profiles.

Abstract
Several disease-modifying drugs (DMDs) are currently approved for the treatment of multiple sclerosis (MS). Recently, there has been increased identification and development of potential new treatments that may modulate the MS disease process, including oral therapies. Many of the newly approved MS therapies, as well as those in ongoing clinical trials, have the advantage of improved efficacy and/or being oral and more convenient, as compared to conventional injectable first-line MS therapies. However, many of these new and emerging MS treatments are known to be associated with serious adverse events, some of which may be potentially life threatening. Of additional concern, there is limited experience and long-term safety data for many of these drugs, and thus the true potential for complications associated with these agents remains ambiguous. With an anticipated explosion in the artillery of available MS therapies in the near future, neurologists will need to carefully weigh drug efficacy, convenience, safety, and tolerability when making therapeutic decisions. In this review, we describe the known mechanisms of action, efficacy, and side-effect profiles of new and emerging MS DMDs.

Abstract
BACKGROUND Teriflunomide is a new oral disease-modifying therapy for relapsing forms of multiple sclerosis. METHODS We concluded a randomized trial involving 1088 patients with multiple sclerosis, 18 to 55 years of age, with a score of 0 to 5.5 on the Expanded Disability Status Scale and at least one relapse in the previous year or at least two relapses in the previous 2 years. Patients were randomly assigned (in a 1:1:1 ratio) to placebo, 7 mg of teriflunomide, or 14 mg of teriflunomide once daily for 108 weeks. The primary end point was the annualized relapse rate, and the key secondary end point was confirmed progression of disability for at least 12 weeks. RESULTS Teriflunomide reduced the annualized relapse rate (0.54 for placebo vs. 0.37 for teriflunomide at either 7 or 14 mg), with relative risk reductions of 31.2% and 31.5%, respectively (P<0.001 for both comparisons with placebo). The proportion of patients with confirmed disability progression was 27.3% with placebo, 21.7% with teriflunomide at 7 mg (P=0.08), and 20.2% with teriflunomide at 14 mg (P=0.03). Both teriflunomide doses were superior to placebo on a range of end points measured by magnetic resonance imaging (MRI). Diarrhea, nausea, and hair thinning were more common with teriflunomide than with placebo. The incidence of elevated alanine aminotransferase levels (≥1 times the upper limit of the normal range) was higher with teriflunomide at 7 mg and 14 mg (54.0% and 57.3%, respectively) than with placebo (35.9%); the incidence of levels that were at least 3 times the upper limit of the normal range was similar in the lower- and higher-dose teriflunomide groups and the placebo group (6.3%, 6.7%, and 6.7%, respectively). Serious infections were reported in 1.6%, 2.5%, and 2.2% of patients in the three groups, respectively. No deaths occurred. CONCLUSIONS Teriflunomide significantly reduced relapse rates, disability progression (at the higher dose), and MRI evidence of disease activity, as compared with placebo.

Abstract
Natalizumab, a highly specific α4-integrin antagonist, is approved for treatment of patients with active relapsing-remitting multiple sclerosis (RRMS). It is generally recommended for individuals who have not responded to a currently available first-line disease-modifying therapy or who have very active disease. The expected benefits of natalizumab treatment have to be weighed against risks, especially the rare but serious adverse event of progressive multifocal leukoencephalopathy. In this Review, we revisit and update previous recommendations on natalizumab for treatment of patients with RRMS, based on additional long-term follow-up of clinical studies and post-marketing observations, including appropriate patient selection and management recommendations.
