Abstract
Objectives Disease-modifying therapy (DMT) for multiple sclerosis (MS) after natalizumab-associated progressive multifocal leukoencephalopathy (PML) is controversial due to concern for recurrent PML. We describe DMT utilization for over a decade in a patient with MS who survived PML. Methods Case report. Results A 36-year-old woman was diagnosed with MS in 2002 and treated with interferon beta-1a until 2006, when she transitioned to natalizumab due to relapses. She presented in 2012 with 2 months of progressive cognitive and gait concerns and was diagnosed with PML by positive CSF JC virus testing with concordant clinical and MRI findings. She was treated with plasma exchange and then corticosteroids for PML immune reconstitution inflammatory syndrome before starting glatiramer acetate for DMT. She transitioned to dimethyl fumarate in 2013 after MS activity on MRI with negative CSF JC virus testing. Owing to worsening footdrop consistent with progression, she transitioned to ocrelizumab in 2017 and then to ofatumumab in 2020 due to logistics of medication administration. There has been no clinicoradiographic or CSF evidence of recurrent PML. Discussion DMT selection is challenging for patients with MS who survive PML. We used an escalation approach extending to ocrelizumab and ofatumumab due to MS progression. Anti-CD20 DMTs are a high-efficacy option post-PML. Classification of Evidence This provides Class IV evidence. It is a single observational study without controls.

J Neurol Sci 2024; 461:123046.

Abstract
INTRODUCTION Progressive multifocal leukoencephalopathy (PML) is a potentially life-threatening complication among Multiple Sclerosis (MS) patients under natalizumab treatment, with serum anti-JCV antibody titers being used for stratification risk. Given the critical role of interferon (IFN)/B-cell activating factor (BAFF) axis in humoral immune responses against viruses, we explored whether it is involved in the generation of serum anti-JCV antibodies among these patients. METHODS 162 consecutive patients with relapsing-remitting MS under natalizumab treatment were included. Serum anti-JCV antibodies were measured at baseline, as well as 12 and 24 months after treatment initiation. Type I and II IFN-inducible genes and BAFF expression were quantitated in peripheral blood by qRT-PCR. Moreover, BAFF rs9514828, rs1041569, and rs9514827 gene variants were assessed by RFLP-PCR. RESULTS While type I and II IFN inducible gene expression were not associated with anti-JCV serum titers, the latter were significantly correlated with BAFF gene expression. Of interest, the TTT haplotype of the studied BAFF variants was more frequently detected in male, but not female anti-JCV (+) MS patients compared to anti-JCV (-) counterparts at baseline, as well as at 12 months and 24 months of natalizumab treatment. Measures of clinical validity/utility for the BAFF TTT haplotype showed 88% specificity, 45%, positive predictive value, and sensitivity of 70% for the discrimination of anti-JCV (+) male MS patients after 24 months of treatment. CONCLUSIONS Our study suggests an implication of the BAFF axis in the production of serum anti-JCV antibodies. Additionally, the BAFF TTT haplotype derived from the rs9514828, rs1041569, and rs9514827 variants may represent a novel risk factor for anti-JCV seropositivity and indirectly for PML development among male MS patients treated with natalizumab.

Front Pharmacol 2024; 15:1376494. [PMID: 38846098 PMCID: PMC11153721 DOI: 10.3389/fphar.2024.1376494] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2024] [Accepted: 05/06/2024] [Indexed: 06/09/2024] Open
Abstract
Objective Sphingosine-1-phosphate receptor (S1PR) modulators have recently attracted increasing attention for the treatment of multiple sclerosis (MS). Despite their preference in the clinic, multiple adverse events (AEs) continue to be reported every year. This study aimed to investigate the potential AEs as well as related important medical events (IMEs) signal associated with S1PR modulators, including fingolimod, siponimod and ozanimod in a real-world study using the FDA Adverse Event Reporting System (FAERS) database. Methods All data were collected from the FAERS database, spanning from the fourth quarter of 2010(2010Q4) to the second quarter of 2023 (2023Q2). Potential AE and IME signals of S1PR modulators were identified based on a disproportionality analysis using the reporting odds ratio (ROR), proportional reporting ratio (PRR), and the bayesian confidence propagation neural network of information components (IC). Results Overall, 276,436 reports of fingolimod, 20,972 reports of siponimod and 10,742 reports of ozanimod were analyzed from the FAERS database. Among reports, females were more prone to develop AEs (73.71% for females vs. 23.21% for males), and more than 50% of patients suffered from AEs were between 18 and 64 years. Subsequently, we investigated the top 20 AEs associated with the signal strength of S1PR modulators at the preferred term (PT) level, and identified 31 (8 vs. 11 vs. 12, respectively) unlabeled risk signals such as thrombosis, uterine disorder and reproductive system and breast disorders. Furthermore, we discovered that the S1PR modulator reported variations in the possible IMEs, and that the IMEs associated with ocular events were reported frequently. It's interesting to note that infection and malignancy are prominent signals with both fingolimod and siponimod in the top 20 PTs related to mortality reports. Conclusion The present investigation highlights the possible safety risks associated with S1PR modulators. The majority of AEs are generally consistent with previous studies and are mentioned in the prescribing instructions, however, several unexpected AE signals have also been observed. Ozanimod showed the lowest signal intensity and a better safety profile than the other S1PR modulators. Due to the short marketing time of drugs and the limitations of spontaneous reporting database, further research is required to identify potential AEs related to S1PR modulators.

Abstract
ABSTRACT Multiple sclerosis (MS) is an immune-mediated inflammatory condition of the central nervous system causing periods of recurring inflammation and ultimately progression of symptoms over time. MS is a common cause of disability in younger patients. Evidence-based treatment for patients with MS early in their disease course prevents relapses and delays progression. Early treatments for MS were classified as immune-modulating; newer developments that suppress the immune system are more effective in preventing future relapses and progression but carry risks. The increased use of immunosuppressant therapies for patients with MS makes it imperative for clinicians to understand potential risks, benefits, and serious adverse reactions related to these therapies.

A phase 2a open-label clinical trial to determine the effect of famciclovir on EBV activity as measured by EBV shedding in the saliva of patients with multiple sclerosis. Mult Scler 2024; 30:63-70. [PMID: 38131621 PMCID: PMC10782647 DOI: 10.1177/13524585231215268] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2023] [Revised: 10/06/2023] [Accepted: 11/01/2023] [Indexed: 12/23/2023]
Abstract
BACKGROUND Despite increasing evidence that Epstein-Barr virus (EBV) plays a causal role in MS, no treatments have been shown to reduce EBV turnover. We studied the effect of famciclovir on salivary EBV shedding in people with MS (NCT05283551) in a pilot, proof-of-concept study. METHODS People with MS receiving natalizumab provided weekly saliva samples for 12 weeks before starting famciclovir 500 mg twice daily for 12 weeks. Twelve saliva samples were provided on treatment and 12 following treatment. A real-time qPCR Taqman assay was used to detect EBV DNA in saliva. The proportion of saliva samples containing EBV DNA was compared using the Friedman test. RESULTS Of 30 participants (19 F; mean age 41 years; median EDSS 3.5), 29 received famciclovir, and 24 completed the 12-week course. Twenty-one participants provided at least one usable saliva sample in all epochs. Ten of the 21 had shedding in at least one sample pre-drug; 7/21 when taking famciclovir (not significant). No difference in EBV DNA copy number was seen. There were no drug-related serious adverse events. CONCLUSION No significant effect of famciclovir on EBV shedding was seen in this small pilot study. Given the low numbers, a small effect of famciclovir cannot be excluded. Salivary EBV shedding in this natalizumab-treated cohort was lower than in previous studies, which requires replication.

Abstract
Fingolimod is an oral medication for the prevention of multiple sclerosis relapse, and its efficacy has been demonstrated in several clinical trials. Fingolimod has various side effects, such as arrhythmia and hepatic dysfunction. In addition, there have been rare reports of the development of lymphoproliferative disorders in patients undergoing fingolimod therapy, including primary central nervous system lymphoma (PCNSL). We diagnosed and treated a multiple sclerosis patient who developed PCNSL while undergoing fingolimod therapy. Fourteen months after starting fingolimod therapy, the patient developed aphasia, and underwent biopsy analysis for a lesion displaying a homogeneous gadolinium-enhanced lesion in the left frontal lobe. The lesion was diagnosed as diffuse large B-cell lymphoma by pathological examination. After the diagnosis, the patient received chemotherapy together with methotrexate combination therapy, and the lesion became smaller and the patient's symptoms improved. Although several autopsy cases of PCNSL in patients who received fingolimod therapy have been reported, there have been few reports to date of patients diagnosed by biopsy analysis.

Abstract
The elderly often suffer from "mild" dementia due to white matter disease, which is another name for repeated brain infarctions. The degeneration of white matter, which links various parts of the brain to the spinal cord, is the root cause of this disorder, which develops with age. Dementia, imbalance, and movement problems are symptoms of this degenerative disease that worsen with age. This research's goal is to study current therapy options and identify methods for early diagnosis of white matter illness. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement for meta-analyses and systematic reviews served as the basis for our literature review. Results from the search in ScienceDirect and Medline/Pubmed led to the finalization of 33 studies. The complex relationship between white matter hyperintensities (WMHs) and neurological disorders is the subject of this comprehensive review, which sheds light on the varied terrain of WMH studies by highlighting their consequences and developing evaluation techniques.

Abstract
Multiple sclerosis (MS) is a chronic, autoimmune, demyelinating disease of the central nervous system (CNS). Microbes, including bacteria and certain viruses, particularly Epstein-Barr virus (EBV), have been linked to the pathogenesis of MS. While there is currently no cure for MS, antibiotics and antivirals have been studied as potential treatment options due to their immunomodulatory ability that results in the regulation of the immune process. The current issue addressed in this systematic review is the effect of antimicrobials, including antibiotics, antivirals, and antiparasitic agents in animals and humans. We performed a comprehensive search of PubMed, Google Scholar, and Scopus for articles on antimicrobials in experimental autoimmune encephalomyelitis animal models of MS, as well as in people with MS (pwMS). In animal models, antibiotics tested included beta-lactams, minocycline, rapamycin, macrolides, and doxycycline. Antivirals included acyclovir, valacyclovir, and ganciclovir. Hydroxychloroquine was the only antiparasitic that was tested. In pwMS, we identified a total of 24 studies, 17 of them relevant to antibiotics, 6 to antivirals, and 1 relevant to antiparasitic hydroxychloroquine. While the effect of antimicrobials in animal models was promising, only minocycline and hydroxychloroquine improved outcome measures in pwMS. No favorable effect of the antivirals in humans has been observed yet. The number and size of clinical trials testing antimicrobials have been limited. Large, multicenter, well-designed studies are needed to further evaluate the effect of antimicrobials in MS.

Abstract
The differential diagnoses of ring-enhancing lesions of the brain parenchyma is broad, but complete ring-enhancing lesions often indicate a neoplastic or infectious process. We present a case of a 70-year-old female with a history of multiple sclerosis (MS) who was not on current disease-modifying therapy (DMT) and was found to have a ring-enhancing lesion that mimicked a high-grade glioma. The patient underwent gross total resection, and histopathologic and molecular analysis revealed a diagnosis of progressive multifocal leukoencephalopathy (PML). A subsequent medical workup on the patient was unrevealing aside from mild lymphopenia. This is a unique case that highlights both an unusual clinical presentation and radiographic appearance of PML. There is a known associated increased risk of PML with the use of some DMTs for MS. However, this case raises the question of the possibility of developing PML years after interferon beta-1a therapy in a patient without overt immunosuppression.

Abstract
Importance Many disease-modifying therapies (DMTs) have been approved for multiple sclerosis (MS) in the past 2 decades. Research evaluating how these approvals have changed real-world prescribing patterns is scarce. Objective To evaluate patterns in DMT initiations between 2001 and 2020 among commercially insured US adults and children with MS. Design, Setting, and Participants This serial cross-sectional study was conducted from 2001 through 2020 (mean patient enrollment duration, 4.8 years) and used US commercial claims data (MarketScan). Analysis took place between January 2022 and March 2023. Of 287 084 patients with MS identified, 113 583 patients (113 095 adults and 488 children) with MS newly initiated at least 1 DMT. Exposure New initiation episode of a DMT, defined as no claim for the same DMT in the previous year. Main Outcome Measure The proportion of total DMT initiations per year attributable to each DMT. Trends in initiations were evaluated annually. Results The study team identified 153 846 DMT initiation episodes among adults (median age, 46 [IQR, 38-53) years]; 86 133 female [76.2%]) and 583 among children (median age, 16 (IQR, 14-17) years; 346 female [70.9%]). Among adults, use of platform injectables showed an absolute decline of 73.8% over the study period, driven by a 61.2% reduction in interferon β initiations (P < .001 for trend). In contrast, the 2010 introduction of oral DMTs led to a rise in their use from 1.1% (2010) to 62.3% (2020) of all DMT initiations (P = .002 for trend). Infusion therapy initiations remained relatively low, accounting for 3.2% of all initiations since their introduction in 2004 but increased modestly annually after ocrelizumab was introduced (2017), reaching 8.2% of all initiations in 2020 (P < .001 for trend). Children showed similar initiation patterns, except for preferred oral therapy. Between 2019 and 2020, dimethyl fumarate was the most commonly initiated DMT in adults (23.3% to 27.2% of all initiations), while in children fingolimod was the most commonly initiated (34.8% to 68.8%). Conclusions and Relevance Current MS treatment guidelines emphasize shared decision-making between patients and clinicians to balance treatment efficacy, safety, cost, and convenience. This study found that oral DMTs were the predominant DMT type initiated by 2020. The cause of this shift cannot be determined from this study, but may reflect several factors, including convenience of administration, direct-to-consumer advertising, or insurance restrictions.

Abstract
INTRODUCTION Multiple sclerosis (MS) is an immune-mediated disorder of the CNS manifested by recurrent attacks of neurological symptoms (related to focal inflammation) and gradual disability accrual (related to progressive neurodegeneration and neuroinflammation). Sphingosine-1-phosphate-receptor (S1PR) modulators are a class of oral disease-modifying therapies (DMTs) for relapsing MS. The first S1PR modulator developed and approved for MS was fingolimod, followed by siponimod, ozanimod, and ponesimod. All are S1P analogues with different S1PR-subtype selectivity. They restrain the S1P-dependent lymphocyte egress from lymph nodes by binding the lymphocytic S1P-subtype-1-receptor. Depending on their pharmacodynamics and pharmacokinetics, they can also interfere with other biological functions. AREAS COVERED Our narrative review covers the PubMed English literature on S1PR modulators in MS until August 2022. We discuss their pharmacology, efficacy, safety profile, and risk management recommendations based on the results of phase II and III clinical trials. We briefly address their impact on the risk of infections and vaccines efficacy. EXPERT OPINION S1PR modulators decrease relapse rate and may modestly delay disease progression in people with relapsing MS. Aside their established benefit, their place and timing within the long-term DMT strategy in MS, as well as their immunological effects in the new and evolving context of the post-COVID-19 pandemic and vaccination campaigns warrant further study.

Abstract
Progressive multifocal leukoencephalopathy (PML) is a subacute CNS inflammatory disease seen primarily among immunocompromised patients. It is caused by the JC virus (JCV), a polyomavirus that otherwise induces an insidious, latent infection in the general population. This reactivated disease is characterized by cognitive and behavioral changes, language disturbances, motor weakness, or visual deficits. Median survival in patients with AIDS is approximately 2-4 months, and mortality is high (around 4% in untreated AIDS). Recent scientific developments indicate that PML can also be associated with the increased utilization of monoclonal antibody (mAb) immunotherapy. In fact, PML has been witnessed with several mAbs, including natalizumab in multiple sclerosis, rituximab for lymphoma or lupus, efalizumab for psoriasis, and ofatumumab in leukemia; this leads us to the risk reassessment of PML due to treatment-induced immunosuppression. The range of clinical presentations of JCV-related disease has transformed over time and can pose significant challenges to the current diagnostic criteria. Most cases with PML suffer from persistent and irreversible neurological conditions, and some with chronic, low-level viral replication in the CNS. With the expanded use of mAbs for various autoimmune and lymphoproliferative disorders, we are now seeing this infection in non-HIV patients on drugs such as natalizumab, rituximab, and other recently approved therapies. This article aims to review the relationship between the incidence of PML and all four mAbs used in the treatment of MS. Currently, at least 18 FDA-approved medications carry label warnings for PML;to this date, no treatment has been convincingly effective.

Abstract
Multiple Sclerosis (MS) is a chronic neurodegenerative autoimmune disorder of the central nervous system (CNS) and the most common cause of serious physical disability in working-age adults. Drug development and research in this field have rapidly evolved over the past two decades, leading to the broad array of treatment options available today. These disease-modifying therapies (DMTs) work through distinct mechanisms of action and exhibit varying safety and efficacy profiles to help manage symptoms and reduce exacerbations in MS patients. Our extensive understanding of this condition has also led to novel approaches, such as the discovery of specific biomarkers that allow us to monitor the therapeutic response towards DMTs. The development of new DMTs continues to progress quickly today, and it can be difficult for clinicians to remain up to date on the most recent advancements and new treatment options for their patients. In this comprehensive review, we provide an outline of current MS medications in the pipeline including emerging DMTs and stem cell therapy, as well as the unique characteristics of these medications, including their indications, pharmacokinetic effects, and the relevant advancements.

Abstract
Background Fingolimod is a sphingosine 1-phosphate receptor modulator approved for
relapsing MS. Long-term effects on the immunological profile are not fully
understood. Objective Investigate fingolimod's temporal effects on immune cell subsets, and safety
outcomes. Methods In FLUENT, a 12-month, prospective, non-randomized, open-label, phase IV
study, adult participants received fingolimod 0.5 mg/day. Changes in immune
cell subsets, anti-John Cunningham virus (JCV) antibody index, and serum
neurofilament levels were assessed. Results 165 fingolimod-naive and 217 participants treated for 2–12 years in routine
clinical practice were enrolled. Levels of all monitored peripheral
lymphocyte subsets were reduced from month 3 in fingolimod-naive
participants. Greatest reductions occurred in naive and central memory
CD4+ and CD8+ T cells, and in naive and memory B cells. Most lymphocyte
subset levels remained stable in the continuous fingolimod group. Components
of the innate immune system remained within reference ranges. No increase in
JCV seropositivity was observed. No single cellular subset correlated with
anti-JCV antibody index at any time point. Neurofilament levels remained
within healthy adult reference limits throughout. No opportunistic
infections were reported; no new or unexpected safety signals were
observed. Conclusion FLUENT provides insights into the utility of immunological profiling to
evaluate therapy response and potential infection risk.

Single-Center Experience on Progressive Multifocal Leukoencephalopathy (PML) cases, neuroimaging relevance, and management at West Virginia University (WVU). J Med Virol 2022; 94:4015-4022.

Abstract
Progressive Multifocal Leukoencephalopathy (PML) is an increasingly common and rapidly fatal demyelinating infection of CNS caused by the highly prevalent JCV in immunocompromised individuals belonging to all age groups and genders. HIV is the most common predisposing factor among other immunodeficient conditions leading to reactivation and multiple neurological symptoms. It has varied findings on MRI and diagnosis is confirmed by positive JC virus in CSF. We report 12 confirmed cases of PML from a single academic center. We comprehensively described clinical presentations, risk factors, CSF and neuroimaging findings, treatment and outcome for these cases of PML, a rare disease. The cases were almost equivalently distributed among young and old age groups and both genders. Positive JC virus on CSF was present in the majority of cases along with mild to severe reduction in lymphocyte counts. Significant MRI changes were present in all cases ranging from T2 hypertense signals to white matter lesions in various regions. Treatment with the reversion of immune-modulators, optimization of antiviral therapy (ART), plasmapheresis (PLEX), IVIG, Mirtazapine, oral steroids, and others was started as soon as the diagnosis was made in the majority of the cases. However, PML is a rapidly fatal illness and hence, survival was only seen in 4 cases in our study. The objective of this article is to highlight the importance of early diagnosis of PML with CSF findings and neuroimaging, early reversion of immunosuppressive medications, and careful monitoring and treatment of HIV cases with goals to reduce mortality, long-term morbidity, and deficits.

The Expanding Role of the Infectious Disease Expert in the Context of the MS Centre. J Pers Med 2022; 12:jpm12040591. [PMID: 35455707 PMCID: PMC9026290 DOI: 10.3390/jpm12040591] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2022] [Revised: 03/26/2022] [Accepted: 04/04/2022] [Indexed: 11/16/2022] Open
Abstract
Introduction: The complexity of the MS patient’s management is constantly growing. Consequently, the MS care unit requires a multidisciplinary approach, including an infectious disease specialist to minimise the risk of infectious complications related both to the disease and DMTs. Materials and methods: We retrospectively evaluated the infectious disease consultations performed from 2015 to 2019 in our MS centre. Results: We identified 107 patients with at least one infectious disease consultation out of 1088 patients. We found a progressive increase in the number of consultations from 2015 to 2019. Nearly half of the consultations were requested at the time of starting MS treatment. The most frequent requests were represented by chronic or acute infections. The most prevalent infectious agents were Herpesviridae and Mycobacterium tuberculosis. Antibiotic or antiviral treatment and prophylactic treatment or vaccination represented together the most frequent outcomes of the consultations. Finally, a treatment delay was significantly associated with the advice of a prophylactic treatment or of a vaccination. Conclusion: There is an increasing awareness of the potential infectious complications of MS and of exposure to DMTs. The interaction between the MS neurologist and infectious disease specialist is fundamental to minimise the infectious risk related to the disease and to the DMTs, with a progressive shift from complication management to a broader prevention workup at the time of MS diagnosis, including both vaccination and prophylactic treatments.

Abstract
Background Progressive multifocal leukoencephalopathy (PML) is a rare demyelinating lytic brain infection caused by the John Cunningham virus (JCV). JCV manifests primarily in patients with innate immunodeficiency or taking immunomodulatory medications. In this case study, we report a PML patient with comorbid mediastinal teratoma and mild lymphopenia. Case presentation A 73-year-old female presented with a 3-month history of progressive hemiplegia, hemianopsia, and cognitive impairment. She was diagnosed as PML by cerebrospinal fluid metagenomics sequencing and brain biopsy. Extensive immunological tests did not reveal an apparent immunodeficiency, but further work-up revealed that the PML was most likely the first presentation of mediastinal teratoma and the mild lymphopenia. Mirtazapine and immunoglobulin were started, the patient’s condition was relatively stable and approved to be discharged from hospital. But unfortunately, she died of the lung infection 10 months after first presentation. Conclusions This case confirms that mediastinal teratoma may induce the lymphopenia and trigger PML, delayed or incorrect diagnosis may worsen the course of the disease and result in poor prognosis.
