The adjudication committee is responsible the evaluation of all relapses reported during the the follow-up period. This is a multicentre, randomized controlled, open-labelled, parallel group study. Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information Due to the immense vacuum in the treatment strategies, investigators have also established established an European consensus on treatment and emphasized on the absolute need for a randomized controlled treatment trials to find an optimal therapeutical strategy in order to reduce risk of sequelae after the first attack and relapses that could reduce disabilities. In a study of children and adults in Australia, maintenance treatment with oral prednisolone was associated with fewer treatment failures than were other treatment modalities, whereas in the European collaborative retrospective study of children with MOG-Abs, investigators were able to confirm that all treatment modalities reduced annualized relapse rates but had limited effects on disability. By contrast, immunomodulatory treatments for MS, such as interferon-β and glatiramer acetate, are ineffective. ![]() Corticosteroids, intravenous immunoglobulin, immunosuppressive drugs (such as mycophenolate mofetil, azathioprine and methotrexate) and rituximab are actually used and are associated with a reduction in annual relapse rate. Studies on prospective treatment of MOGAD are rare and current treatment is based on clinical experience with similar antibody-mediated diseases, such as AQP4-Abs positive NMOSD. In that study, it was observed that although the majority of children had low level clinical disability, 20% of affected children had cognitive impairment and investigators confirmed these results in the national cohort study where they have observed that age at onset < or = 10 years (OR, 3.72, 95%CI 1.19-11.64 p=0.024), ADEM at onset (OR 52.5, 95%CI 5.97-461.4 p<0.001), and deep grey matter lesions (OR, 17.33 95%CI 3.87-77.72 p<0.001) were associated to the presence of cognitive difficulties. Recently, Bicêtre's hospital medical team have performed a multi-national collaborative study on 102 children with relapsing MOG-Abs-ADS (RADS) through a European Consortium coordinated by the coordinator of this project. ![]() These presentations may vary according to the age and young children 70% of this disability results from the onset attack, suggesting that there is room for improvement in the acute management of MOG-Ab-associated disease, and that time to treatment might be important for the prevention of permanent disability. Studies have shown that in MOG-Abs positive ADS, the most frequent clinical phenotype in children are ADEM-like presentations (ADEM, ADEM-optic neuritis, multiphasic demyelinating encephalomyelitis (MDEM) and encephalitis) and optic neuritis (ON). Recently, myelin oligodendrocyte glycoprotein (MOG) antibodies (MOG-Abs) have been found implicated in ADS affecting children with a frequency up to 30%-45% according to tested cohorts. MOG-Abs-ADS are a frequent disease in children with ADS with specific clinical and MRI pattern. It begins as monophasic diseases, as often observed in acute demyelinating encephalomyelitis (ADEM), optic neuritis (ON) and transverse myelitis (TM) or as multiphasic disease with relapses such as multiple sclerosis (MS) or neuromyelitis optica spectrum disorders (NMOSD). ADS can affect adult and children, and the clinical spectrum is heterogenous. Why Should I Register and Submit Results?Īcquired Demyelinating Syndrome (ADS) are rare immune-mediated central nervous system (CNS) disorders that contribute to significant neurological morbidity in Europe and worldwide.
