Características clínicas del espectro de la enfermedad asociada a los anticuerpos contra la glucoproteína del oligodendrocito asociada a la mielina

Introduction. Myelin oligodendrocyte glycoprotein (MOG) antibody disease is a rare and practically new entity in medicine. In developing countries, there are still important limitations for the detection of anti-MOG antibodies by cell-based assay, so knowing the clinical characteristics of the different phenotypes and their differences with other demyelinating pathologies of the central nervous system is essential in order to make a proper diagnostic and therapeutic approach of the patients. Aim. To present an update regarding the clinical characteristics of the disease spectrum, being the first article in Spanish that gathers the most frequent phenotypes and provides a clear description of what should be considered to identify each of these phenotypes. Development. This disease is characterized by having a monophasic or recurrent course, with optic neuritis being the most frequent presentation phenotype in general population and disseminated acute encephalomyelitis the most frequent in children. Other phenotypes described in this review are transverse myelitis, focal cortical encephalitis and cerebral stem syndromes, as well as the proposed criteria for the diagnosis of the disease associated with MOG antibody disease. Conclusion. Currently there are no studies that seek to characterize the Spanish-speaking population with this disease, or review articles in Spanish, so it is important to disseminate knowledge and develop research in this area.
