[PMID: 38214014 PMCID: PMC10783644 DOI: 10.1093/braincomms/fcad358] [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: 03/28/2023] [Revised: 10/25/2023] [Accepted: 01/01/2024] [Indexed: 01/13/2024] Open
Abstract
Fingolimod is a frequently used disease-modifying therapy in relapsing-remitting multiple sclerosis. However, case reports and small observational studies indicate a highly increased risk of disease reactivation after discontinuation. We aimed to investigate the risk of radiological disease reactivation in patients discontinuing fingolimod. We performed a nationwide cohort study in Denmark, including patients who discontinued fingolimod between January 2014 and January 2023. Eligibility was a diagnosis with relapsing-remitting multiple sclerosis and two MRIs performed respectively within 1 year before and after discontinuing fingolimod. The included patients were compared with those discontinuing dimethyl fumarate with the same eligibility criteria in an unadjusted and matched propensity score analysis. Matching was done on age, sex, Expanded Disability Status Scale, MRI data, cause for treatment discontinuation, treatment duration and relapse rate. The main outcome was the presence of new T2 lesions on the first MRI after treatment discontinuation. To identify high-risk patients among those discontinuing fingolimod, we made a predictive model assessing risk factors for obtaining new T2 lesions. Of 1324 patients discontinuing fingolimod in the study period, 752 were eligible for inclusion [mean age (standard deviation), years, 41 (10); 552 females (73%); median Expanded Disability Status Scale (Q1-Q3), 2.5 (2.0-3.5); mean disease duration (standard deviation), years, 12 (8)]. Of 2044 patients discontinuing dimethyl fumarate in the study period, 957 were eligible for inclusion, presenting similar baseline characteristics. Among patients discontinuing fingolimod, 127 (17%) had 1-2 new T2 lesions, and 124 (17%) had ≥3 new T2 lesions compared with 114 (12%) and 45 (5%), respectively, for those discontinuing dimethyl fumarate, corresponding to odds ratios (95% confidence interval) of 1.8 (1.3-2.3) and 4.4 (3.1-6.3). The predictive model, including 509 of the 752 patients discontinuing fingolimod, showed a highly increased risk of new T2 lesions among those with disease activity during fingolimod treatment and among females under 40 years. This nationwide study suggests that discontinuing fingolimod in some cases carries a risk of developing new T2 lesions, emphasizing the importance of clinical awareness. If feasible, clinicians should prioritize the prompt initiation of new disease-modifying therapies, particularly among young females.

Maunula A, Atula S, Laakso SM, Tienari PJ. Frequency and risk factors of rebound after fingolimod discontinuation - A retrospective study. Mult Scler Relat Disord 2024; 81:105134. [PMID: 37980790 DOI: 10.1016/j.msard.2023.105134] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2023] [Revised: 08/18/2023] [Accepted: 11/10/2023] [Indexed: 11/21/2023]
Abstract
BACKGROUND Fingolimod (FTY) rebound, a phenomenon of unexpectedly severe disease activity following FTY discontinuation, has been reported to occur in 5-43 % of patients. Only a few larger cohorts have been analyzed. We aimed to determine the frequency and risk factors of FTY rebound in our hospital district in Southern Finland with a population of 1.7 million. METHODS We searched the Finnish MS-register for patients who were previous or current users of FTY for at least 6 months by November 2020. We assessed medical records and collected basic demographic data for the whole cohort. Criteria for a rebound were: (i) the most severe relapse in patient's history and an increase of at least 2 EDSS points during the relapse occurring within 6 months from FTY cessation, or (ii) more than one relapse within 6 months after FTY discontinuation, this being the highest relapse rate observed during the patient's lifetime. RESULTS Among 3496 MS patients, we found 331 patients ever starting FTY and 283 of them had used FTY for at least 6 months. Among these 283 patients we discovered a total of 114 discontinuation events in 110 patients. Of the discontinuations, 32 (28 %) were followed by a relapse: 20 (17.5 %) were ordinary relapses not fulfilling rebound criteria, and 12 (10.5 %) were rebounds. The median time to an ordinary relapse and rebound were similar: 8.5 weeks (range 1.3-23) and 9.9 weeks (range 5.9-15.9), respectively. The rebound group was younger at diagnosis (p = 0.034) and had used FTY for a longer time (p = 0.048) before discontinuation compared to the group without a relapse. After discontinuation, rebound group had lower lymphocyte values as compared to both ordinary relapse group (p = 0.027) and no-relapse group (p = 0.006) and neutrophil to lymphocyte ratio (NLR) was increased compared to the no-relapse group (p = 0.019). CONCLUSION In this study, 10.5 % of patients experienced a rebound, which is similar to the frequencies (10.3-12.5 %) obtained in other larger studies with >100 discontinuations. Relapses of any severity occurred in 28 % of patients discontinuing FTY, and therefore initiation of subsequent disease modifying therapies should occur promptly after discontinuation. Younger age at diagnosis, longer exposure to FTY and lower lymphocyte count as well as higher NLR after discontinuation were identified as risk factors for a rebound. The differences in blood leukocytes indicate that rebound might be a distinct pathophysiological phenomenon compared to an ordinary relapse.

Multiple faces of multiple sclerosis in the era of highly efficient treatment modalities: Lymphopenia and switching treatment options challenges daily practice. Int Immunopharmacol 2023; 125:111192.

Abstract
The expanded treatment landscape in relapsing-remitting multiple sclerosis (MS) has resulted in highly effective treatment options and complexity in managing disease- or drug-related events during disease progression. Proper decision-making requires thorough knowledge of the immunobiology of MS itself and an understanding of the main principles behind the mechanisms that lead to secondary autoimmunity affecting organs other than the central nervous system as well as opportunistic infections. The immune system is highly adapted to both environmental and disease-modifying agents. Immune reconstitution following cell depletion or cell entrapment therapies eliminates pathogenic aspects of the disease but can also lead to distorted immune responses with harmful effects. Atypical relapses occur with second-line treatments or after their discontinuation and require appropriate clinical decisions. Lymphopenia is a result of the mechanism of action of many drugs used to treat MS. However, persistent lymphopenia and cell-specific lymphopenia could result in disease exacerbation, secondary autoimmunity, or the emergence of opportunistic infections. Clinicians treating patients with MS should be aware of the multiple faces of MS under novel, efficient treatment modalities and understand the intricate brain-immune cell interactions in the context of an altered immune system. MS relapses and disease progression still occur despite the current treatment modalities and are mediated either by failure to control effector mechanisms inherent to MS pathophysiology or by new drug-related mechanisms. The multiple faces of MS due to the highly adapted immune system of patients impose the need for appropriate switching therapies that safeguard disease remission and further clinical improvement.

Abstract
INTRODUCTION Neuromyelitis optica spectrum disorders (NMOSD) is an autoimmune, inflammatory disease of the central nervous system affecting the optic nerves and spinal cord. Most NMOSD patients have autoantibodies against the astrocyte water channel protein aquaporin-4 (AQP4). Eculizumab treatment is used effectively and safely in AQP4-IgG+ NMOSD. Our study evaluated the prognosis and outcomes of all clinical trial (PREVENT) patients from Turkey who received eculizumab treatment for AQP4-IgG+ NMOSD. METHOD Clinical and demographic data of all patients enrolled in the PREVENT and OLE clinical trial in Turkey were analyzed during the study period and after the study ended. Clinical follow-up results were recorded in detail in patients who had to discontinue eculizumab treatment. RESULTS The study included 10 patients who participated in PREVENT and OLE. Seven patients completed the studies, three patients did not continue the study and were switched to other treatments. Only one of the seven patients was able to continue treatment after eculizumab was approved in AQP4-IgG+NMOSD. The other six patients could not continue treatment due to reimbursement conditions. Four of the six patients who could not continue eculizumab treatment experienced early relapse (within the first three months after stopping the drug). All of these patients had high disease activity before eculizumab and had never relapsed under eculizumab treatment over the long term. CONCLUSION Eculizumab was used effectively and safely in Turkish AQP4-IgG+NMOSD patients with high disease activity. Disease reactivation and relapse may occur after discontinuation of eculizumab treatment in patients with a long-term stable course. In these cases, close monitoring for disease reactivation is recommended.

Rituximab De-escalation in Patients With Neuromyelitis Optica Spectrum Disorder. Neurology 2023; 101:e438-e450. [PMID: 37290967 PMCID: PMC10435052 DOI: 10.1212/wnl.0000000000207443] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2022] [Accepted: 04/07/2023] [Indexed: 06/10/2023] Open
Abstract
BACKGROUND AND OBJECTIVES Exit strategies such as de-escalations have not been evaluated for rituximab in patients with neuromyelitis optica spectrum disorder (NMOSD). We hypothesized that they are associated with disease reactivations and aimed to estimate this risk. METHODS We describe a case series of real-world de-escalations from the French NMOSD registry (NOMADMUS). All patients met the 2015 International Panel for NMO Diagnosis (IPND) diagnostic criteria for NMOSD. A computerized screening of the registry extracted patients with rituximab de-escalations and at least 12 months of subsequent follow-up. We searched for 7 de-escalation regimens: scheduled discontinuations or switches to an oral treatment after single infusion cycles, scheduled discontinuations or switches to an oral treatment after periodic infusions, de-escalations before pregnancies, de-escalations after tolerance issues, and increased infusion intervals. Rituximab discontinuations motivated by inefficacy or for unknown purposes were excluded. The primary outcome was the absolute risk of NMOSD reactivation (one or more relapses) at 12 months. AQP4+ and AQP4- serotypes were analyzed separately. RESULTS We identified 137 rituximab de-escalations between 2006 and 2019 that corresponded to a predefined group: 13 discontinuations after a single infusion cycle, 6 switches to an oral treatment after a single infusion cycle, 9 discontinuations after periodic infusions, 5 switches to an oral treatment after periodic infusions, 4 de-escalations before pregnancies, 9 de-escalations after tolerance issues, and 91 increased infusion intervals. No group remained relapse-free over the whole de-escalation follow-up (mean: 3.2 years; range: 0.79-9.5), except pregnancies in AQP+ patients. In all groups combined and within 12 months, reactivations occurred after 11/119 de-escalations in patients with AQP4+ NMOSD (9.2%, 95% CI [4.7-15.9]), from 0.69 to 10.0 months, and in 5/18 de-escalations in patients with AQP4- NMOSD (27.8%, 95% CI [9.7-53.5]), from 1.1 to 9.9 months. DISCUSSION There is a risk of NMOSD reactivation whatever the rituximab de-escalation regimen. TRIAL REGISTRATION INFORMATION Registered on ClinicalTrials.gov: NCT02850705. CLASSIFICATION OF EVIDENCE This study provides Class IV evidence that de-escalation of rituximab increases the probability of disease reactivation.

NEUROLOGY(R) NEUROIMMUNOLOGY & NEUROINFLAMMATION 2023; 10:10/4/e200110. [PMID: 37217309 DOI: 10.1212/nxi.0000000000200110] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/13/2022] [Accepted: 02/08/2023] [Indexed: 05/24/2023]
Abstract
BACKGROUND AND OBJECTIVE Discontinuation of fingolimod ≥2 months before pregnancy is recommended to minimize potential teratogenicity. The magnitude of MS pregnancy relapse risk, particularly severe relapses, after fingolimod cessation is unclear, as is whether this risk is reduced by pregnancy or modifiable factors. METHODS Pregnancies who stopped fingolimod treatment within 1 year before or during pregnancy were identified from the German MS and Pregnancy Registry. Data were collected through structured telephone-administered questionnaires and neurologists' notes. Severe relapses were defined as a ≥2.0 increase in Expanded Disability Status Scale (EDSS) or new or worsening relapse-related ambulatory impairment. Women who continued to meet this definition 1 year postpartum were classified as reaching the Severe Relapse Disability Composite Score (SRDCS). Multivariable models accounting for measures of disease severity and repeated events were used. RESULTS Of the 213 pregnancies among 201 women (mean age at pregnancy onset 32 years) identified, 56.81% (n = 121) discontinued fingolimod after conception. Relapses during pregnancy (31.46%) and the postpartum year (44.60%) were common. Nine pregnancies had a severe relapse during pregnancy and additional 3 during the postpartum year. One year postpartum, 11 of these (6.32% of n = 174 with complete EDSS information) reached the SRDCS. Adjusted relapse rates during pregnancy were slightly higher compared with the year before pregnancy (relapse rate ratio = 1.24, 95% CI 0.91-1.68). Neither exclusive breastfeeding nor resuming fingolimod within 4 weeks of delivery were associated with a reduced risk of postpartum relapses. Most pregnancies relapsed during the first 3 months postpartum (n = 55/204, 26.96%). DISCUSSION Relapses during pregnancy after fingolimod cessation are common. Approximately 6% of women will retain clinically meaningful disability from these pregnancy-related, fingolimod cessation relapses 1 year postpartum. This information should be shared with women on fingolimod desiring pregnancy, and optimizing MS treatment with nonteratogenic approaches should be discussed.

Abstract
Multiple sclerosis (MS) is an immune-driven disease that affects the central nervous system and is characterized by acute-on-chronic demyelination attacks. It is a major cause of global neurological disability, and its prevalence has increased in the United States. Conceptual understandings of MS have evolved over time, including the identification of B cells as key factors in its pathophysiology. The foundation of MS management involves preventing flares so as to avoid long-term functional decline. Treatments may be categorized into low-, middle-, and high-efficacy medications based on their efficacy in relapse prevention. With 24 FDA-approved treatments for MS, individual therapy is chosen based on distinct mechanisms and potential side effects. This review provides a detailed update on the epidemiology, diagnosis, treatment advances, and major ongoing research investigations in MS.

Abstract
Multiple sclerosis is a disease that tends to affect women during their childbearing years. Although relapse risk decreases during pregnancy, patients should still be optimized on disease-modifying therapy before and after pregnancy to minimize gaps in treatment. Exclusive breastfeeding may reduce the chances of disease relapse postpartum, and many disease-modifying therapies are considered to be safe while breastfeeding. Treatments for other neuroimmunologic disorders such as neuromyelitis optica spectrum disorder, myelin oligodendrocyte glycoprotein antibody-associated disease, neurosarcoidosis, and central nervous system vasculitis may require rituximab before and prednisone or intravenous immunoglobulin therapy during pregnancy.

Anemoside B4 ameliorates experimental autoimmune encephalomyelitis in mice by modulating inflammatory responses and the gut microbiota. Eur J Pharmacol 2022; 931:175185. [PMID: 35987252 DOI: 10.1016/j.ejphar.2022.175185] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2022] [Revised: 08/01/2022] [Accepted: 08/02/2022] [Indexed: 11/03/2022]
Abstract
BACKGROUND Anemoside B4 (AB4) is a representative component of Pulsatilla decoction that is used in traditional Chinese medicine for treating inflammatory conditions. It is not known whether AB4 has beneficial effects on multiple sclerosis (MS). METHODS In the present study, we examined the preventative and therapeutic effects of AB4, and the possible mechanism by which it protects female mice against experimental autoimmune encephalomyelitis (EAE). RESULTS Preventative treatment with AB4 (given orally at 100 and 200 mg/kg for 18 days) reduced the clinical severity of EAE significantly (from 3.6 ± 1.3 to 1.8 ± 1.5 and 1.6 ± 0.6, respectively), and inhibited demyelination and inflammatory infiltration of the spinal cord. In the therapeutic protocol, oral administration of 200 mg/kg AB4 for 21 days after initiation of EAE significantly alleviated disease severity (from 2.6 ± 1.3 to 0.9 ± 0.6) and was as effective as the clinically used drug fingolimod (0.3 ± 0.6). Furthermore, both doses of AB4 significantly inhibited mRNA expression of TNF-α, IL-6, and IL-17, and STAT3 activation, in the spinal cord; and the ex vivo and iv vitro AB4 treatment markedly inhibited secretion of the three cytokines from lymphocytes of EAE mice upon in vitro restimulation. In addition, AB4 reversed the changes in the composition of the intestinal microbiome observed in EAE mice. CONCLUSION We reveal for the first time that AB4 protects against EAE by modulating inflammatory responses and the gut microbiota, demonstrating that AB4 may have potential as a therapeutic agent for treating MS in humans.

Abstract
Background There is growing interest in the issue of disease reactivation in multiple sclerosis following fingolimod cessation. Relatively little is known about modifiers of the risk of post-cessation relapse, including the delay to commencement of new therapy and prior disease activity. Objective We aimed to determine the rate of relapse following cessation of fingolimod and to identify predictors of relapse following cessation. Methods Data were extracted from the MSBase registry in March 2019. Inclusion criteria were (a) clinically definite relapsing multiple sclerosis, (b) treatment with fingolimod for ≥ 12 months, (c) follow-up after cessation for ≥ 12 months, and (d) at least one Expanded Disability Status Scale score recorded in the 12 months before cessation. Results A total of 685 patients were identified who met criteria. The mean annualised relapse rate was 1.71 (95% CI 1.59, 1.85) in the year prior to fingolimod, 0.50 (95% CI 0.44, 0.55) on fingolimod and 0.43 (95% CI 0.38, 0.49) after fingolimod. Of these, 218 (32%) patients experienced a relapse in the first 12 months. Predictors of a higher relapse rate in the first year were: younger age at fingolimod cessation, higher relapse rate in the year prior to cessation, delaying commencement of new therapy and switching to low-efficacy therapy. Conclusions Disease reactivation following fingolimod cessation is more common in younger patients, those with greater disease activity prior to cessation and in those who switch to a low-efficacy therapy.

Abuse and dependence potential of sphingosine-1-phosphate (S1P) receptor modulators used in the treatment of multiple sclerosis: a review of literature and public data. Psychopharmacology (Berl) 2022; 239:1-13. [PMID: 34773483 PMCID: PMC8770388 DOI: 10.1007/s00213-021-06011-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/06/2021] [Accepted: 10/18/2021] [Indexed: 12/05/2022]
Abstract
Abuse and misuse of prescription drugs remains an ongoing concern in the USA and worldwide; thus, all centrally active new drugs must be assessed for abuse and dependence potential. Sphingosine-1-phosphate (S1P) receptor modulators are used primarily in the treatment of multiple sclerosis. Among the new S1P receptor modulators, siponimod, ozanimod, and ponesimod have recently been approved in the USA, European Union (EU), and other countries. This review of literature and other public data has been undertaken to assess the potential for abuse of S1P receptor modulators, including ozanimod, siponimod, ponesimod, and fingolimod, as well as several similar compounds in development. The S1P receptor modulators have not shown chemical or pharmacological similarity to known drugs of abuse; have not shown abuse or dependence potential in animal models for subjective effects, reinforcement, or physical dependence; and do not have adverse event profiles demonstrating effects of interest to individuals who abuse drugs (such as sedative, stimulant, mood-elevating, or hallucinogenic effects). In addition, no reports of actual abuse, misuse, or dependence were identified in the scientific literature for fingolimod, which has been on the market since 2010 (USA) and 2011 (EU). Overall, the data suggest that S1P receptor modulators are not associated with significant potential for abuse or dependence, consistent with their unscheduled status in the USA and internationally.

Abstract
For patients with autoimmune diseases, the risks and benefits of immunosuppressive or immunomodulatory treatment are a matter of continual concern. Knowledge of the follow-up routine for each drug is crucial, in order to attain better outcomes and avoid new disease activity or occurrence of adverse effects. To achieve control of autoimmune diseases, immunosuppressive and immunomodulatory drugs act on different pathways of the immune response. Knowledge of the mechanisms of action of these drugs and their recommended doses, adverse reactions and risks of infection and malignancy is essential for safe treatment. Each drug has a specific safety profile, and management should be adapted for different circumstances during the treatment. Primary prophylaxis for opportunistic infections and vaccination are indispensable steps during the treatment plan, given that these prevent potential severe infectious complications. General neurologists frequently prescribe immunosuppressive and immunomodulatory drugs, and awareness of the characteristics of each drug is crucial for treatment success. Implementation of a routine before, during and after use of these drugs avoids treatment-related complications and enables superior disease control.

Abstract
Fingolimod (FTY) is a disease modifying therapy for relapsing remitting multiple sclerosis (RRMS) which can lead to severe lymphopenia requiring therapy discontinuation in order to avoid adverse events. However, this can result in severe disease reactivation occasionally presenting with tumefactive demyelinating lesions (TDLs). TDLs, which are thought to originate from a massive re-entry of activated lymphocytes into the central nervous system, are larger than 2 cm in diameter and may feature mass effect, perifocal edema, and gadolinium enhancement. In these cases, it can be challenging to exclude important differential diagnoses for TDLs such as progressive multifocal leukoencephalopathy (PML) or other opportunistic infections. Here, we present the case of a 26-year-old female patient who suffered a massive rebound with TDLs following FTY discontinuation with primarily neuropsychiatric symptoms despite persisting lymphopenia. Two cycles of seven plasmaphereses each were necessary to achieve remission and ocrelizumab was used for long-term stabilization.

Abstract
Background It is still controversial whether the relapse experienced after discontinuation of fingolimod treatment is a rebound. Increasing cases of rebound have been reported in the literature. The rate of fingolimod rebound in patients after fingolimod cessation is reported between 5% and 52%. The present study aims to determine the rate of rebound after discontinuation of fingolimod treatment and the factors affecting the rebound. Methods This retrospective cohort study consists of adult MS patients who have been admitted to the Hacettepe University Hospital Neurology MS Center outpatient clinic between 2012 and 2020. Results During the study period, 642 patients received fingolimod and 23.1% discontinued the fingolimod treatment. Thirteen of 126 patients had a rebound (10.3%) after fingolimod discontinuation. The patients in the rebound group were significantly younger and washout period were significantly longer than those in the non-rebound group. After discontinuation of fingolimod treatment, the EDSS score of the rebound group was significantly higher than the non-rebound group, while Annualized Relapse Rates were similar. Conclusion Younger age, longer washout time, and previous treatment preferences may increase the occurrence probability of rebound. It is recommended that patients should be closely monitored after fingolimod discontinuation and appropriate disease-modifying therapy should be initiated as soon as possible.

Abstract
Abstract:The Canadian Multiple Sclerosis Working Group has updated its treatment optimization recommendations (TORs) on the optimal use of disease-modifying therapies for patients with all forms of multiple sclerosis (MS). Recommendations provide guidance on initiating effective treatment early in the course of disease, monitoring response to therapy, and modifying or switching therapies to optimize disease control. The current TORs also address the treatment of pediatric MS, progressive MS and the identification and treatment of aggressive forms of the disease. Newer therapies offer improved efficacy, but also have potential safety concerns that must be adequately balanced, notably when treatment sequencing is considered. There are added discussions regarding the management of pregnancy, the future potential of biomarkers and consideration as to when it may be prudent to stop therapy. These TORs are meant to be used and interpreted by all neurologists with a special interest in the management of MS.

Abstract
Because the treatment of multiple sclerosis (MS) may span decades, the need often arises to make changes to the treatment plan in order to accommodate changing circumstances. Switching drugs, or the discontinuation of immunomodulatory agents altogether, may leave patients vulnerable to relapse or disease progression. In some cases, severe MS disease activity is noted clinically and on MRI after treatment withdrawal. When this disease activity is disproportionate to the pattern observed prior to treatment initiation, patients are said to have experienced rebound. Of the US Food and Drug Administration (FDA)-approved agents to treat MS, the drugs most commonly implicated in rebound are natalizumab and fingolimod. In this review based on the reported cases and data from clinical trials, we characterize disease rebound after fingolimod cessation. We also outline fingolimod rebound management considerations, summarizing what evidence is available to help clinicians mitigate the risk of rebound, switch therapies, and treat rebound events when they occur. The commonly encountered situation of fingolimod discontinuation prior to pregnancy is also discussed.

Combination of cannabinoids, delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD), mitigates experimental autoimmune encephalomyelitis (EAE) by altering the gut microbiome. Brain Behav Immun 2019; 82:25-35. [PMID: 31356922 PMCID: PMC6866665 DOI: 10.1016/j.bbi.2019.07.028] [Citation(s) in RCA: 75] [Impact Index Per Article: 15.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/21/2019] [Revised: 07/17/2019] [Accepted: 07/25/2019] [Indexed: 02/07/2023] Open
Abstract
Currently, a combination of marijuana cannabinoids including delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD) is used as a drug to treat muscle spasticity in patients with Multiple Sclerosis (MS). Because these cannabinoids can also suppress inflammation, it is unclear whether such patients benefit from suppression of neuroinflammation and if so, what is the mechanism through which cannabinoids act. In the currently study, we used a murine model of MS, experimental autoimmune encephalomyelitis (EAE), to study the role of gut microbiota in the attenuation of clinical signs of paralysis and inflammation caused by cannabinoids. THC + CBD treatment attenuated EAE and caused significant decrease in inflammatory cytokines such as IL-17 and IFN-γ while promoting the induction of anti-inflammatory cytokines such as IL-10 and TGF-β. Use of 16S rRNA sequencing on bacterial DNA extracted from the gut revealed that EAE mice showed high abundance of mucin degrading bacterial species, such as Akkermansia muciniphila (A. muc), which was significantly reduced after THC + CBD treatment. Fecal Material Transfer (FMT) experiments confirmed that THC + CBD-mediated changes in the microbiome play a critical role in attenuating EAE. In silico computational metabolomics revealed that LPS biosynthesis, a key component in gram-negative bacteria such as A. muc, was found to be elevated in EAE mice which was confirmed by demonstrating higher levels of LPS in the brain, while treatment with THC + CBD reversed this trend. EAE mice treated with THC + CBD also had significantly higher levels of short chain fatty acids such as butyric, isovaleric, and valeric acids compared to naïve or disease controls. Collectively, our data suggest that cannabinoids may attenuate EAE and suppress neuroinflammation by preventing microbial dysbiosis seen during EAE and promoting healthy gut microbiota.
