Project description:BackgroundOpsoclonus-myoclonus syndrome (OMS) is a rare neurological disorder that is characterized by involuntary eye movements and myoclonus. OMS exhibits various etiologies, including paraneoplastic, parainfectious, toxic-metabolic, and idiopathic causes. The exact immunopathogenesis and pathophysiology of OMS are uncertain.Case reportWe report the case of a 19-year-old male who developed opsoclonus and myoclonus several days after a flu-like illness. Serological tests revealed acute mumps infection. The findings of cerebrospinal fluid examinations and brain magnetic resonance imaging were normal. During the early phase of the illness, he suffered from opsoclonus and myoclonus that was so severe as to cause acute renal failure due to rhabdomyolysis. After therapies including intravenous immunoglobulin, the patient gradually improved and had fully recovered 2 months later.ConclusionsThis is the first report of OMS associated with mumps infection in Korea. Mumps infection should be considered in patients with OMS.

Opsoclonus myoclonus ataxia syndrome in severe acute respiratory syndrome coronavirus-2.

Project description:A patient presented with an opsoclonus-myoclonus-ataxia syndrome after a 2-week period of fever. In her work as an assistant nurse, she had been exposed to patients infected with severe acute respiratory syndrome coronavirus-2. Laboratory investigations showed that the patient had positive IgG antibodies against this pathogen, and a chest CT showed changes compatible with this infection. Other known causes for this syndrome were excluded. Our case shows that the opsoclonus-myoclonus-ataxia syndrome can occur as a post-/para-infectious manifestation in patients infected with severe acute respiratory syndrome coronavirus-2.

Absence of GluD2 Antibodies in Patients With Opsoclonus-Myoclonus Syndrome.

Project description:ObjectiveA recent study showed glutamate receptor delta 2 antibodies (GluD2-ab) in sera of patients with opsoclonus-myoclonus syndrome (OMS). Inconsistencies between cerebellar immunoreactivity and expression of GluD2 led us to hypothesize that these antibodies are not biomarkers of OMS.MethodsSerum of 45 children with OMS (10 [22%] with neuroblastoma), 158 adults with OMS (53 [34%] with tumors), and 172 controls including 134 patients with several types of neurologic disorders, 18 with neuroblastoma without OMS, and 20 healthy participants were investigated. Antibodies were determined with 3 different techniques: (1) rat brain immunohistochemistry, (2) a live cell-based assay using a standard secondary antibody (2-step CBA), and (3) a similar CBA with a secondary and tertiary antibodies (3-step CBA). Two plasmids were used in the CBA studies. Three commercial GluD2-ab and 2 human sera with GluD2-ab served as controls for expression of GluD2.ResultsThe 3 commercial GluD2-ab showed predominant reactivity with the molecular and Purkinje cell layers (where GluD2 is highly enriched), and were also positive with the indicated CBAs. Substantially milder reactivity with brain tissue and CBA was obtained with the 2 control human sera containing GluD2-ab. None of the 203 patients with OMS and 172 controls showed immunoreactivities consistent with GluD2-abs. Compared with a standard 2-step CBA, the 3-step assay did not improve antibody detection and showed more frequent nonspecific reactivity that was not immunoabsorbed with GluD2.ConclusionWe did not find GluD2-ab in a large cohort of patients with OMS. GluD2-ab should not be considered diagnostic biomarkers of OMS.
