FTY720 increases paclitaxel efficacy in cisplatin-resistant oral squamous cell carcinoma.

BACKGROUND: Oral squamous cell carcinoma has high recurrence and cisplatin resistance. As cancer stem cells, autophagy, and sphingolipids have been appointed as associated with chemotherapy resistance, we tested combined treatments targeting autophagy and/or sphingolipid metabolism with paclitaxel using cisplatin-resistant oral squamous cell carcinoma cells. METHODS: Cisplatin-resistant oral squamous cell carcinoma cells were maintained under exposition to FTY720 and chloroquine combined with paclitaxel and submitted to viability, clonogenicity, and spheres formation assays. The xenograft tumor model using cisplatin-resistant CAL27 cells was adopted to examine the drug combinations' potential antitumoral efficacy. Using an animal model, sphingolipids profiles from plasma and tissue samples were obtained by liquid chromatography coupled to mass spectrometry to identify potential lipids associated with drug response. RESULTS AND DISCUSSION: Our results showed higher autophagic flux in cisplatin-resistant Ooral squamous cell carcinoma (CAL27 and SCC9) cells than in parental cells. The combinations of an autophagy inhibitor (chloroquine) or an autophagy inducer/sphingosine kinase 1 antagonist (FTY720) with paclitaxel (PTX) had a synergistic antitumor effect. Treated CisR cells lost clonogenicity and tumor sphere abilities and reduced proteins associated with proliferation, survival, and cancer stem cells. FTY720 plus PTX had higher antitumor efficacy than PTX against CAL27 CisR xenograft tumor formation. Additionally, increases in glucosylceramide, dehydroglucosylceramide, and sphingomyelin were presented in responsive tumors. CONCLUSION: FTY720 sensitizes cisplatin-resistant oral squamous cell carcinoma cells for paclitaxel.

Histoplasmosis in a fingolimod-treated patient: case report and scoping review

ABSTRACT Fingolimod is a sphingosine-1-phosphate receptor modulator used to treat multiple sclerosis. While fingolimod has been associated with an increased risk of cryptococcal meningitis, its correlation with other deep mycoses remains unclear. In this study, we conducted a scoping review of fingolimod associated with histoplasmosis, based on a case report, a literature review, and data from the FDA Adverse Events Reporting System (FAERS) as of January 24th, 2023. A 30-year-old Brazilian woman diagnosed with relapsing-remitting multiple sclerosis, receiving a daily dose of 0.5 mg of fingolimod, presented with a two-month history of fever and unintended weight loss, accompanied by lymphadenopathy, splenomegaly, and lung involvement was investigated. Biopsy of a lung nodule revealed fungal structures suggestive of Histoplasma sp. Additionally, serological testing yielded positive for Histoplasma capsulatum. Disseminated histoplasmosis should be considered in the differential diagnosis of febrile syndromes in patients undergoing fingolimod therapy for multiple sclerosis, particularly in the Americas, where this mycosis is endemic. Treatment with itraconazole and modification of immunotherapy can achieve excellent clinical outcomes.

Primary central nervous system lymphoma in a patient with multiple sclerosis using fingolimod.

Primary central nervous system lymphoma (PCNSL) is an uncommon lymphoproliferative disease associated with immunosuppression. Here, we report the case of a patient with multiple sclerosis, under treatment with fingolimod (FTY720, Gilenya) for 4 years, who developed this condition. Although the causal relationship cannot be established, there are cases in the literature that describe the appearance of lymphoma after the use of this medication. Considering the high mortality of PCNSL, epidemiological studies are necessary to establish a relationship between its arising and the use of immunosuppressants.

ZEB1 is a Subgroup-Specific Marker of Prognosis and Potential Drug Target in Medulloblastoma.

Medulloblastoma (MB) is a malignant brain tumor that afflicts mostly children and adolescents and presents four distinct molecular subgroups, known as WNT, SHH, Group 3, and Group 4. ZEB1 is a transcription factor that promotes the expression of mesenchymal markers while restraining expression of epithelial and polarity genes. Because of ZEB1 involvement in cerebellum development, here we investigated the role of ZEB1 in MB. We found increased expression of ZEB1 in MB tumor samples compared to normal cerebellar tissue. Expression was higher in the SHH subgroup when compared to all other MB molecular subgroups. High ZEB1 expression was associated with poor prognosis in Group 3 and Group 4, whereas in patients with WNT tumors poorer prognosis were related to lower ZEB1 expression. There was a moderate correlation between ZEB1 and MYC expression in Group 3 and Group 4 MB. Treatment with the immunomodulator and histone deacetylase (HDAC) inhibitor fingolimod (FTY720) reduced ZEB1 expression specifically in D283 cells, which are representative of Group 3 and Group 4 MB. These findings reveal novel subgroup-specific associations of ZEB1 expression with survival in patients with MB and suggest that ZEB1 expression can be reduced by pharmacological agents that target HDAC activity.

The antiinflammatory and electrophysiological effects of fingolimod on penicillin-induced rats / Os efeitos antiinflamatórios e eletrofisiológicos do fingolimode em ratos induzidos pela penicilina

Abstract Background The fact that inflammation triggers epileptic seizures brings to mind the antiepileptic properties of anti-inflammatory drugs. Objective To investigate the electrophysiological and anti-inflammatory effects of fingolimod on an experimental penicillin-induced acute epileptic seizure model in rats. Methods Thirty-two male Wistar rats were divided into four groups: control (penicillin), positive control (penicillin + diazepam [5 mg/kg]), drug (penicillin + fingolimod [0.3 mg/kg]) and synergy group (penicillin + diazepam + fingolimod). The animals were anesthetized with urethane, and epileptiform activity was induced by intracortical injection of penicillin (500,000 IU). After electrophysiological recording for 125 minutes, IL-1β, TNF-α, and IL-6 were evaluated by ELISA in the serum of sacrificed animals. Results During the experiment, animal deaths occurred in the synergy group due to the synergistic negative chronotropic effect of diazepam and fingolimod. Although not statistically significant, fingolimod caused a slight decrease in spike-wave activity and spike amplitudes in the acute seizure model induced by penicillin (p > 0.05). Fingolimod decreased serum IL-1β (p < 0.05); fingolimod and diazepam together reduced IL-6 (p < 0.05), but no change was observed in serum TNF-α values. Conclusion Even in acute use, the spike-wave and amplitude values of fingolimod decrease with diazepam, anticonvulsant and anti-inflammatory effects of fingolimod will be more prominent in chronic applications and central tissue evaluations. In addition, concomitant use of fingolimod and diazepam is considered to be contraindicated due to the synergistic negative inotropic effect.

Resumo Antecedentes O fato de a inflamação desencadear crises epilépticas traz à mente as propriedades antiepilépticas dos anti-inflamatórios. Objetivo Investigar os efeitos eletrofisiológicos e anti-inflamatórios do fingolimode em um modelo experimental de crise epiléptica aguda induzida por penicilina em ratos. Métodos Trinta e dois ratos Wistar machos foram divididos em quatro grupos: controle (penicilina), controle positivo (penicilina + diazepam [5 mg/kg]), droga (penicilina + fingolimode [0,3 mg/kg]) e grupo sinergia (penicilina + diazepam + fingolimode). Os animais foram anestesiados com uretano, e a atividade epileptiforme foi induzida por injeção intracortical de penicilina (500.000 UI). Após registro eletrofisiológico por 125 minutos, IL-1β, TNF-α e IL-6 foram avaliados por ELISA no soro dos animais sacrificados. Resultados Durante o experimento, ocorreram mortes de animais no grupo sinérgico devido ao efeito cronotrópico negativo sinérgico do diazepam e do fingolimode. Embora não seja estatisticamente significativo, o fingolimode causou uma ligeira diminuição na atividade pico-onda e nas amplitudes pico no modelo de convulsão aguda induzida pela penicilina (p > 0,05). O fingolimode diminuiu a IL-1β sérica (p < 0,05); fingolimode e diazepam juntos reduziram a IL-6 (p < 0,05), mas não foi observada alteração nos valores séricos de TNF-α. Conclusão Pensa-se que o efeito anticonvulsivante leve de uma dose única de fingolimode será mais proeminente em aplicações crônicas e em avaliações de tecidos centrais. Além disso, o uso concomitante de fingolimode e diazepam é considerado contraindicado devido ao efeito inotrópico negativo sinérgico.

Heart rate assessment after the first dose of Fingolimod / Avaliação da frequência cardíaca após a primeira dose de Fingolimode

To evaluate the cardiovascular function of patients who received the first dose of Fingolimod in a health center in the state of Rio Grande do Sul ­ Brazil. Methods: A retrospective database study, gathering clinical data and patients' electrocardiograms who received the first dose of Fingolimod 0.5mg at Centro de Diagnóstico Cardiológico from May 2013 to October 2020. Results: From 83 patients evaluated 64 (77.1%) were women. The average age of participants was 36.97 (±11.21) years old. Out of the 22 (26.5%) symptomatic patients, drowsiness was the most common symptom. There was a statistically significant difference (p<0.0001) in the heart rate that occurred early from the first hour after taking the medicine and went on to the fifth hour. Regarding systolic blood pressure, there was a difference (p <0.0001) between the measurement before taking the drug and the measurement six hours later. However, there was no difference in systolic pressure every hour between the second hour after drug administration. The same that happened to systolic blood pressure occurred to diastolic blood pressure. There was no statistical correlation between the age group and the analyzed variables. Conclusions: The clinical, hemodynamic, and electrocardiographic changes verified in the study sample were mild and resolved within 6 hours after the dose, which allows the use of this drug to treat MS safely in the analyzed group.

Objetivo: Avaliar a função cardiovascular de pacientes que receberam a primeira dose de Fingolimode em um centro de saúde do estado do Rio Grande do Sul ­ Brasil. Métodos: Estudo retrospectivo de banco de dados, reunindo dados clínicos e eletrocardiogramas de pacientes que receberam a primeira dose de Fingolimode 0,5mg no Centro de Diagnóstico Cardiológico de maio de 2013 a outubro de 2020. Resultados: Dos 83 pacientes avaliados, 64 (77,1%) eram mulheres. A média de idade dos participantes foi de 36,97 (±11,21) anos. Dos 22 (26,5%) pacientes sintomáticos, a sonolência foi o sintoma mais comum. Houve diferença estatisticamente significativa (p<0,0001) na frequência cardíaca que ocorreu desde a primeira hora após a administração do medicamento até a quinta hora. Em relação à pressão arterial sistólica, houve diferença (p<0,0001) entre a medida antes de tomar o medicamento e a medida seis horas depois. No entanto, não houve diferença na pressão sistólica a cada hora entre a segunda hora após a administração do medicamento. O mesmo que aconteceu com a pressão arterial sistólica ocorreu com a pressão arterial diastólica. Não houve correlação estatística entre a faixa etária e as variáveis Analisadas. Conclusões: As alterações clínicas, hemodinâmicas e eletrocardiográficas verificadas na amostra estudada foram leves e se resolveram em até 6 horas após a dose, o que permite o uso desse medicamento para o tratamento da SM com segurança no grupo analisado.

Brain volume loss and physical and cognitive impairment in naïve multiple sclerosis patients treated with fingolimod: prospective cohort study in Buenos Aires, Argentina / Perda de volume cerebral e comprometimento físico e cognitivo em pacientes recém-diagnosticados com esclerose múltipla tratados com fingolimode: estudo de coorte prospectivo em Buenos Aires, Argentina

Abstract Background The percentage of brain volume loss (PBVL) has been classically considered as a biomarker in multiple sclerosis (MS). Objective The objective of the present study was to analyze if the PBVL during the 1st year after the onset of the disease predicts physical and cognitive impairment (CI). Methods Prospective study that included naïve patients without cognitive impairment who initiated MS treatment with fingolimod. Patients were followed for 3 years and relapses, expanded disability status scale (EDSS) progression (defined as worsening of 1 point on the EDSS), the annual PBVL (evaluated by structural image evaluation using normalization of atrophy [SIENA]), and the presence of CI were evaluated. Cognitive impairment was defined in patients who scored at least 2 standard deviations (SDs) below controls on at least 2 domains. The PBVL after 1 year of treatment with fingolimod was used as an independent variable, while CI and EDSS progression at the 3rd year of follow-up as dependent variables. Results A total of 71 patients were included, with a mean age of 35.4 ± 3 years old. At the 3rd year, 14% of the patients were classified as CI and 6.2% had EDSS progression. In the CI group, the PBVL during the 1st year was-0.52 (± 0.07) versus-0.42 (± 0.04) in the no CI group (p < 0.01; odds ratio [OR] = 2.24; 95% confidence interval [CI]: 1.72-2.44). In the group that showed EDSS progression, the PBVL during the 1st year was - 0.59 (± 0.05) versus - 0.42 (± 0.03) (p < 0.01; OR = 2.33; 95%CI: 1.60-2.55). Conclusions A higher PBVL during the 1st year in naïve MS patients was independently associated with a significant risk of CI and EDSS progression.

Resumo Antecedentes A porcentagem de perda de volume cerebral (PPVC) é um biomarcador na esclerose múltipla (EM). Objetivo Analisar se a PPVC durante o 1° ano após o início da doença prediz deterioração física (DF) e cognitiva (DC) em pacientes com EM. Métodos Estudo de coorte prospectivo que incluiu pacientes recém-diagnosticados sem comprometimento cognitivo que iniciaram tratamento com fingolimode. Os pacientes foram acompanhados por 3 anos, sendo avaliados a presença de recidivas, progressão da Escala Expandida do Estado de Incapacidade (EDSS, na sigla em inglês) (definida como agravamento de 1 ponto na EDSS), o PPVC anual (avaliado pela avaliação de imagem estrutural de atrofia normalizada [SIENA, na sigla em inglês) e a presença de DC (avaliada no início do estudo e nos 2° e 3° anos). O PPVC no 1° ano de tratamento com fingolimode foi utilizado como variável independente. Resultados foram incluídos 71 pacientes com idade média de 35,4 ± 3 anos. No 3° ano, 14% dos pacientes tiveram DC e 6,2% tiveram progressão de EDSS. No grupo DC, o PPVC durante o 1o ano foi - 0,52 (± 0,07) versus - 0,42 (± 0,04) no grupo sem DC (p<0,01; razão de probabilidades [OR, na sigla em inglês] =2,24; intervalo de confiança [IC] de 95%: 1,72-2,44). No grupo que apresentou progressão da EDSS, o PPVC durante o 1° ano foi de - 0,59 (± 0,05) versus - 0,42 (± 0,03) (p < 0,01; OR = 2,33; IC95%: 1,60-2,55). Conclusões Um maior PPVC durante o 1° ano foi associado a um risco significativo de progressão de DC e EDSS durante o seguimento.

Modulating Fingolimod (FTY720) Anti-SARS-CoV-2 Activity Using a PLGA-Based Drug Delivery System.

COVID-19 has resulted in more than 490 million people being infected worldwide, with over 6 million deaths by April 05th, 2022. Even though the development of safe vaccine options is an important step to reduce viral transmission and disease progression, COVID-19 cases will continue to occur, and for those cases, efficient treatment remains to be developed. Here, a drug repurposing strategy using nanotechnology is explored to develop a therapy for COVID-19 treatment. Nanoparticles (NPs) based on PLGA for fingolimod (FTY720) encapsulation show a size of ∼150 nm and high drug entrapment (∼90%). The NP (NP@FTY720) can control FTY720 release in a pH-dependent manner. Cytotoxicity assays using different cell lines show that NP@FTY720 displays less toxicity than the free drug. Flow cytometry and confocal microscopy reveal that NPs are actively internalized mostly through caveolin-mediated endocytosis and macropinocytosis pathways and co-localized with lysosomes. Finally, NP@FTY720 not only exhibits anti-SARS-CoV-2 activity at non-cytotoxic concentrations, but its biological potential for viral infection inhibition is nearly 70 times higher than that of free drug treatment. Based on these findings, the combination of drug repurposing and nanotechnology as NP@FTY720 is presented for the first time and represents a promising frontline in the fight against COVID-19.

The budgetary impact of alemtuzumab in multiple sclerosis in Quito, Ecuador. Payer's perspective.

Introduction: Multiple sclerosis is a neurological condition that causes disabilities and is most common in young adults. It imposes high financial costs affecting the quality of life of patients, families, and society. It is critical to measure the budgetary impact of new technologies to treat this disease. Objective: The aim of the article is to estimate the budgetary impact of introducing alemtuzumab as an escalation therapy in patients diagnosed with Recurrent Remitting Multiple Sclerosis and treated in Quito, Ecuador. Materials and methods: A cohort of 85 patients receiving treatment with disease-modifying therapies was used, within a 5-year timeframe, between 2021 and 2025. The baseline scenario, including the percentages of administration of the different drugs, is compared with the alternative scenario, including alemtuzumab. The cost assessment included only direct medical resources. To obtain local resources for management of the disease, a neurologist and clinical expert who treats most of the patients in Quito was consulted. Results: Considering a cohort of 85 patients with active Recurrent Remitting Multiple Sclerosis, the average global budget impact in 5 years would be USD 10,603,230.00 in the base case and USD 9,995,817.00 in the alemtuzumab scenario. Conclusion: The inclusion of alemtuzumab as escalation therapy represents budgetary savings over the next 5 years (2021-2025).

Esclerosis múltiple: reacciones adversas a medicamentos en pacientes bajo ley 20850, Hospital Regional de Talca / Multiple sclerosis: adverse drug reactions in patients under law 20850, Hospital Regional de Talca

INTRODUCTION: Multiple sclerosis (MS) is a demyelinating disease of the central nervous system, which occurs in up to 85% of cases as relapsing remitting (RR), with episodes of neurological dysfunction partially forwarded. Its treatment in Chile is financially protected by the Explicit Health Guarantees (GES) and Law 20,850 on high-cost diseases. The Regional Hospital of Talca (HRT) has 25 patients benefiting from Law 20,850 in treatment with second-line biologic therapy. Adverse reactions (RAM) to the use of these drugs have been described and to date there are no case reports or studies of significant adverse events in Chile. Objectives: To present the experience of the use of biologic therapy in EMRR in HRT, in relation to adverse events. METHODS: A review of the current guidelines in Chile for the treatment of relapsing-remitting multiple sclerosis and the protocol of law 20,850 was carried out, the clinical records of 25 patients benefiting from the law in the HRT were reviewed, with emphasis on the adverse events presented before First and second line therapies and the con sequences of these events on the continuity of therapy. RESULTS: Half of the patients who started their treatment with first-line drugs had adverse effects, of which 28% involved a change in therapy, the remaining changed from therapy due to failure to treatment. Of the 26 patients included in the sample, 24 are currently using second-line drugs. The profile of adverse effects should be a variable to consider when indicating a therapy for MS.

Multiple sclerosis and related disorders: Short report peripheral vascular events in a real-world cohort of multiple sclerosis patients using Fingolimod.

BACKGROUND: Fingolimod is a high-efficacy disease-modifying therapy for multiple sclerosis (MS) and was the first oral treatment approved for the disease. Adverse events include bradyarrhythmia, hypertension, macular oedema and increased risk of infections, mainly due to its main mechanism of action, the non-selective modulation of sphingosine-1-phosphate receptor. METHODS AND RESULTS: We report the baseline characteristics, effectiveness outcomes and adverse events of a prospective cohort of 177 patients with a median treatment duration of 24 months, in which four patients (2.3%) presented with otherwise non-provoked peripheral vascular events (PVE). CONCLUSIONS: Further studies are still needed to evaluate the frequency and severity of PVE in fingolimod patients.

Severe fingolimod rebound syndrome after switching to cladribine treatment.

We present the clinical and imaging characteristics of a patient whom presented with rebound syndrome after switching from fingolimod to cladribine treatment due to hematologic toxicity. Previous imaging studies had shown a non-aggressive phenotype of the disease, however multiple active tumefactive lesions became evident after beginning treatment with cladribine. The patient responded well to plasmapheresis.

Cost-Effectiveness of Natalizumab Compared With Fingolimod for Relapsing-Remitting Multiple Sclerosis Treatment in Colombia.

OBJECTIVES: Multiple sclerosis (MS) is a degenerative neurological disorder. Treatment aims to avoid relapses and disability progression. The purpose of this study was to evaluate the cost-effectiveness of natalizumab compared with fingolimod for treating highly active relapsing-remitting MS (RRMS) patients from the Colombian third-party payer perspective. METHODS: We used a Markov economic model from the perspective of the Colombian healthcare system to estimate the cost-effectiveness of natalizumab compared with fingolimod for RRMS with high disease activity or failure of interferons as first-line therapy. This model was centered on disability progression and relapses. We considered a 5-year time horizon with a 5% discount rate. We included only direct medical costs. Local experts were consulted to obtain resource utilization estimates, and local standardized costing methodologies and sources were used. Outcome was considered in terms of quality-adjusted life-years (QALYs). Utilities were extracted or calculated from the literature. Transition probabilities were calculated from available efficacy and safety information (1 USD = 3050.98 COP). RESULTS: Natalizumab showed lower total costs (USD 80 024 vs USD 98 137) and higher QALY yield (3.01 vs 2.94) than fingolimod, dominating it (incremental cost-effectiveness ratio = -$1861). Univariate sensitivity analysis showcased the relevance of the measures of effect on disability progression for natalizumab on model results. Probabilistic sensitivity analysis replicated base-case results in most simulations. CONCLUSIONS: This study showed that natalizumab dominated fingolimod with lower costs and higher QALYs in patients with high-activity RRMS. These results are consistent with previous published international literature.

Fingolimod (FTY720) reduces viability and survival and increases histone H3 acetylation in medulloblastoma cells.

Histone deacetylase inhibitors (HDACis) are epigenetic agents that display antitumor activities in experimental medulloblastoma (MB). Fingolimod (FTY720), an immunosuppressant agent currently used in the treatment of multiple sclerosis, also has anticancer actions and can act as an HDACi. Here we examined whether fingolimod can inhibit human MB cell viability and survival, and if the effects are accompanied by increased histone acetylation. D283 and DAOY MB cells were treated with different doses of fingolimod. Cell viability was assessed by cell counting in a hemocytometer, and cell survival was analyzed with a colony formation assay. Histone H3 acetylation was measured with an enzyme-linked immunosorbent assay (ELISA). Fingolimod at 7.5 or 10 µM, but not at 5 µM, induced a significant reduction in cell viability in D283 and DAOY cultures, and similar results were observed for inhibition of cell survival. In both cell lines, fingolimod also led to a significant increase in the levels of acetylated H3. These findings provide preliminary evidence indicating that fingolimod induces antitumor activities in MB, possibly through a mechanism which increases H3 histone acetylation.

Fingolimod for the treatment of multiple sclerosis in French West Indies, a real-world study in patients from African ancestry.

Affecting 2.5 million people worldwide, multiple sclerosis (MS) is one of the main causes of acquired disability among young adults. In French West Indies (FWI), where MS has arisen from the end of the 80's, a low therapeutic response to interferons beta1 (IFN beta1) in patients of African descent, restrains the therapeutic options. Fingolimod is a Sphingosine-1-Phosphate receptor modulator whose efficacy in the treatment of MS has recently been shown in three phase III studies. Nevertheless, data are currently lacking concerning the use of Fingolimod among populations of African descent, particularly in a real-world setting. Efficacy and safety information collected during the first two years of follow-up have been analysed retrospectively for all patients in whom Fingolimod treatment was introduced in FWI between its marketing date and December 2015. Fifty-two consecutive patients with a relapsing remitting MS started Fingolimod therapy in the FWI, according to the European guidelines. After 24 months, 40 patients were still receiving the treatment. The average Annualized Relapse Rate (ARR) dropped by 81%, and 72.5% of patients remained free from disability progression during the 24 months on Fingolimod. MS remained controlled (according NEDA 3 criteria) for 41% of patients who were still on therapy at 24 months. Nine participants presented with a moderate or major side effect. Unlike IFN beta1 therapy, Fingolimod appears to be effective in Afro-Caribbean patients in a real-world setting with a similar benefit to what has been observed in phase III studies in more selected populations.

Fingolimod para el tratamiento de esclerosis múltiple remitente-recurrente / Fingolimod for the treatment of sclerosis multiple sender-recurrent

INTRODUCCIÓN: Este documento técnico se realiza a solicitud del Hospital María Auxiliadora, a través de la Gerencia Macro Regional Centro Medio del Seguro Integral de Salud. Tecnología sanitaria: Fingolimod disminuye la infiltración de linfocitos patógenos en el sistema nervioso central reduciendo la inflamación y lesión del tejido nervioso, mediante un mecanismo de antagonismo funcional de los receptores de la esfingosina-1-fosfato (S1P) en los linfocitos. La dosis recomendada es 0,5 mg por vía oral una vez al día. Se han informado como principales eventos adversos (EA) serios infecciones, edema macular y bloqueos auriculoventriculares transitorios, mientras que los EA más frecuentes son dolor de cabeza, elevaciones de enzimas hepáticas, diarrea, tos, gripe, sinusitis y dolor de espalda. Su uso se indica en adultos y pacientes pediátricos mayores de 10 años. Fingolimod cuenta con aprobación de Food and Drug Administration (FDA) de los Estados Unidos desde el año 2010 para el tratamiento de EMRR. En Perú, cuenta con cuatro registros sanitarios vigentes. OBJETIVO: Describir la evidencia científica disponible sobre el uso de fingolimod para el tratamiento de la EMRR. METODOLOGÍA: La pregunta PICO fue la siguiente, P: pacientes con EMRR; I: fingolimod 0,5 mg; C: placebo y otras terapias modificadoras de la enfermedad con registro sanitario vigente en Perú; O: recaídas, progresión de la discapacidad, lesiones observadas en resonancia magnética, calidad de vida y eventos adversos. Se realizó una búsqueda sistemática en Medline (Pubmed), The Cochrane Library y LILACS; la cual se complementó con la búsqueda de evidencia en páginas institucionales de agencias gubernamentales y buscadores genéricos. Se priorizó la identificación y selección de ensayos clínicos aleatorizados controlados (ECAs), revisiones sistemáticas (RS) con o sin meta-análisis (MA) de ECAs, guías de práctica clínica (GPC), evaluaciones de tecnología sanitaria (ETS) y evaluaciones económicas (EE) de América Latina. La calidad de la evidencia se valoró usando las siguientes herramientas: AMSTAR 2 para RS, la herramienta propuesta por la colaboración RESULTADOS: Se identificó dos RS, cuatro ETS y una GPC que respondieron a la pregunta PICO de interés. En relación a la eficacia, se encontró que la tasa anualizada de recaídas fue significativamente menor con fingolimod frente a placebo a los 6, 12 y 24 meses; pero su reducción fue inferior a la de alemtuzumab y natalizumab. La progresión de discapacidad a los 12 meses fue similar entre fingolimod y placebo, y ligeramente menor que placebo a los 24 meses. A los 3 meses, alemtuzumab, natalizumab, dimetil fumarato, interferón y teriflunomida produjeron menor riesgo de progresión que fingolimod. Fingolimod incrementó significativamente la probabilidad de no presentar lesiones realzadas con gadolinio en resonancia magnética a los 6, 12 y 24 meses; y disminuyó significativamente el promedio de lesiones potenciadas en la secuencia T2 en resonancia magnética a los 12 meses. Finalmente, no se reportaron diferencias significativas en la calidad de vida entre fingolimod y placebo.Cochrane para ECAs y AGREE II para GPC. CONCLUSIONES: -En comparación con placebo, fingolimod produjo efectos significativos sobre la disminución de lesiones cerebrales observadas en resonancia magnética y recaídas, y mejoró ligeramente la progresión de la enfermedad a los 24 meses, sin efectos sobre la calidad de vida; -Alemtuzumab y natalizumab fueron los medicamentos con mayor eficacia en la disminución de recaídas y progresión de discapacidad que fingolimod; -Dos ETS de Reino Unido y Argentina recomiendan fingolimod en EMRR altamente activa refractaria a interferón-ß.

Beneficial Effects of the Calcium Channel Blocker CTK 01512-2 in a Mouse Model of Multiple Sclerosis.

Voltage-gated calcium channels (VGCCs) play a critical role in neuroinflammatory diseases, such as multiple sclerosis (MS). CTK 01512-2 is a recombinant version of the peptide Phα1ß derived from the spider Phoneutria nigriventer, which inhibits N-type VGCC/TRPA1-mediated calcium influx. We investigated the effects of this molecule in the mouse model of experimental autoimmune encephalomyelitis (EAE). The effects of CTK 01512-2 were compared to those displayed by ziconotide-a selective N-type VGCC blocker clinically used for chronic pain-and fingolimod-a drug employed for MS treatment. The intrathecal (i.t.) treatment with CTK 01512-2 displayed beneficial effects, by preventing nociception, body weight loss, splenomegaly, MS-like clinical and neurological scores, impaired motor coordination, and memory deficits, with an efficacy comparable to that observed for ziconotide and fingolimod. This molecule displayed a favorable profile on EAE-induced neuroinflammatory changes, including inflammatory infiltrate, demyelination, pro-inflammatory cytokine production, glial activation, and glucose metabolism in the brain and spinal cord. The recovery of spatial memory, besides a reduction of serum leptin levels, allied to central and peripheral elevation of the anti-inflammatory cytokine IL-10, was solely modulated by CTK 01512-2, dosed intrathecally. The intravenous (i.v.) administration of CTK 01512-2 also reduced the EAE-elicited MS-like symptoms, similarly to that seen in animals that received fingolimod orally. Ziconotide lacked any significant effect when dosed by i.v. route. Our results indicate that CTK 01512-2 greatly improved the neuroinflammatory responses in a mouse model of MS, with a higher efficacy when compared to ziconotide, pointing out this molecule as a promising adjuvant for MS management.

Cerebral toxoplasmosis in an MS patient receiving Fingolimod.

Multiple Sclerosis (MS) is an autoimmune disease in which lymphocytes target putative myelin antigens in the CNS, causing inflammation and neurodegeneration. Fingolimod (FTY720) is an immunosuppressive drug used as a second line therapy for relapsing forms of MS due to its safety profile and good response to treatment. Despite its safety, there are still concerns about the possibility of Fingolimod being linked to the development of opportunistic infections like disseminated varicella zoster infections and herpes simplex encephalitis. In this case report, we describe one patient with past medical history of MS in current treatment with Fingolimod for the last year which presents herself with hemiparesis, fever and fatigue. The initial MRI showed multiple demyelinating-like lesions that could have corresponded to the tumefactive form of MS relapse. The blood work up revealed leukopenia with lymphopenia and a CD4+ count of 200 cell/mm3. Treatment for acute relapse was initiated with little to no response. Further examination was carried by the clinicians, a lumbar puncture was performed and it showed pleocytosis with increased protein levels. Later, several serologic studies were performed and both IgM and IgG antibodies for Toxoplasma were positive. Diagnosis of cerebral toxoplasmosis was made and there was no evidence of HIV infection or other causes of secondary immunodeficiency in this patient, except the use of fingolimod. Evidence of decreased levels of CD4+ due to Fingolimod use is concerning. The risk of opportunistic infections in these patients must be considered in order to start or continue therapy with these agents. Further studies are needed to determine the percentage of the population at risk of immunosuppression and its long-term consequences as well as new actions to prevent infections.

Multiple sclerosis treatment with fingolimod: profile of non-cardiologic adverse events.

Fingolimod was the first oral medication approved for management of multiple sclerosis and is currently used by tens of thousands patients worldwide. Fingolimod acts via the sphingosine 1-phosphate (S1P) receptor, maintaining peripheral lymphocytes entrapped in the lymph nodes. In consequence, there is a reduction in the infiltration of aggressive lymphocytes into the central nervous system. The drug is safe and effective, and its first hours of use are associated with related to S1P receptors in the heart. This side effect is well known by all doctors prescribing fingolimod. However, the drug has other potential adverse events that, although relatively rare, require awareness from the neurologist. Among these there are infections (herpes simplex, herpes zoster, Cryptococcus, Epstein-Barr virus, hepatitis, Molluscum Contagiosum, and leishmaniosis), lung and thyroid complications, refractory headaches, encephalopathy, vasculopathy, tumefactive lesions in magnetic resonance imaging and ophthalmological disorders. The present review lists the non-cardiologic adverse events that all neurologists prescribing fingolimod should be aware of.

Patients' satisfaction with and views about treatment with disease-modifying drugs in multiple sclerosis / Satisfação e pontos de vista dos pacientes com esclerose múltipla em tratamento com drogas modificadoras da doença

ABSTRACT Objective The treatment of multiple sclerosis (MS) with disease-modifying-drugs (DMDs) is evolving and new drugs are reaching the market. Efficacy and safety aspects of the drugs are crucial, but the patients’ satisfaction with the treatment must be taken into consideration. Methods Individual interview with patients with MS regarding their satisfaction and points of view on the treatment with DMDs. Results One hundred and twenty eight patients attending specialized MS Units in five different cities were interviewed. Over 80% of patients were very satisfied with the drugs in use regarding convenience and perceived benefits. The only aspect scoring lesser values was tolerability. Conclusion Parameters for improving treatment in MS must include efficacy, safety, and patient satisfaction with the given DMD.

RESUMO Objetivo O tratamento da esclerose múltipla (EM) com drogas-modificadoras-da-doença (DMDs) está evoluindo e novas drogas estão sendo comercializadas. Eficácia e segurança são aspectos cruciais nas medicações, porém a satisfação do paciente com o tratamento deve ser levada em consideração. Métodos Entrevista individual com pacientes com EM investigando a satisfação e ponto de vista desta população em relação ao tratamento com DMDs. Resultados Cento e vinte e oito pacientes atendidos em unidades especializadas de EM de cinco cidades diferentes foram entrevistados. Mais de 80% dos pacientes estava bastante satisfeito com as medicações utilizadas, considerando aspectos de conveniência de uso e benefício das drogas. O único aspecto que pontuou menos foi tolerabilidade. Conclusão Parâmetros para melhor tratamento de EM devem incluir eficácia, segurança e satisfação dos pacientes com a DMD prescrita.
