- Anti-MOG (Myelin Oligodendrocyte Glycoprotein)-Positive Severe Optic Neuritis with Optic Disc Ischaemia and Macular Star(2015) MOURA, Frederico Castelo; SATO, Douglas Kazutoshi; RIMKUS, Carolina Medeiros; APOSTOLOS-PEREIRA, Samira Luisa; OLIVEIRA, Luana Michelli de; LEITE, Claudia Costa; FUJIHARA, Kazuo; MONTEIRO, Mario Luiz Ribeiro; CALLEGARO, DagobertoA 44-year-old man presented with severe right visual loss. The right fundus examination showed marked optic disc oedema associated with partial macular star. Serological blood tests for infectious agents were all negative. Serum aquaporin-4 antibody was negative but anti-MOG (myelin oligodendrocyte glycoprotein) was positive. Magnetic resonance revealed extensive lesion in right optic nerve. There was no visual improvement after intravenous therapy. Patient had no further attacks after follow-up. Optic disc oedema with macular star is found in several infectious and non-inflammatory disorders, but it has not been reported in optic neuritis (ON) associated with autoantibodies to myelin oligodendrocyte glycoprotein (anti-MOG).
- Fingolimod Prescribed for the Treatment of Multiple Sclerosis in Patients Younger Than Age 18 Years(2015) FRAGOSO, Yara Dadalti; ALVES-LEON, Soniza Vieira; BARREIRA, Amilton Antunes; CALLEGARO, Dagoberto; FERREIRA, Maria Lucia Brito; FINKELSZTEJN, Alessandro; GOMES, Sidney; GONCALVES, Marcus Vinicius Magno; MACHADO, Maria Iris Moraes; MARQUES, Vanessa Daccach; MATTA, Andre Palma Cunha; PAPAIS-ALVARENGA, Regina Maria; PEREIRA, Samira Luisa Apostolos; TAUIL, Carlos BernardoBACKGROUND: There have been no clinical trials for approval of medications for treating multiple sclerosis in patients younger than age 18 years. All treatments are based on personal experience and data from open observational studies. Fingolimod is an oral drug for multiple sclerosis that has been shown to be efficient and safe in adults. The aim of our study is to describe patients with multiple sclerosis who started treatment with fingolimod before the age of 18 years. PARTICIPANTS AND METHODS: Seventeen patients treated with fingolimod were identified in the Brazilian database of children and adolescents with multiple sclerosis. The average time of use of the drug was 8.6 months. RESULTS: Fingolimod showed a good safety and efficacy profile in these patients, all of whom had very active multiple sclerosis. After starting treatment with fingolimod, only one patient had a relapse and a new lesion on magnetic resonance imaging. The patients' degree of disability did not progress. No major adverse events were reported in relation to the first dose of the drug, nor in the short- and medium-term treatment. No patient has been followed for longer than 18 months, thus limiting long-term conclusions. CONCLUSIONS: Off-label use of fingolimod in patients younger than age 18 years may be a good therapeutic option for multiple sclerosis control.
- Natalizumab treatment in multiple sclerosis: the experience from two Brazilian MS centers(2015) OLIVEIRA, Enedina Maria Lobato de; SIMM, Renata Faria; DASIC, Gorana; MORAIS, Marilia Mamprim de; PERREIRA, Samira Luiza dos Apostolos; CALLEGARO, DagobertoObjective: Analyze the demographics, clinical characteristics, efficacy and safety of natalizumab treatment in Brazilian patients with multiple sclerosis (MS) followed up for at least 12 months, in two tertiary MS care centers in Sao Paulo. Method: We evaluated the effect of natalizumab treatment on annualized relapse rate and disability progression in 75 patients with MS treated with natalizumab for at least 12 months. A subgroup analysis was performed to evaluate efficacy of natalizumab treatment in patients with Expanded Disability Status Scale (EDSS) <= 3.0 vs patients with EDSS > 3. Results: Patients treated for at least one year with natalizumab showed a 91% reduction in aRR, as well and an improvement in neurological disability. The impact of natalizumab treatment was greater in patients with EDSS < 3.0. Overall, natalizumab was safe but one patient developed progressive multifocal leukoencephalopathy. Conclusion: Natalizumab as a third line therapy is safe and efficacious, especially in patients with mild neurological disability.
