  • Clinical, seizure features in acute phase and short-term prognosis of anti-NMDAR and anti-LGI1 encephalitis: a control study

    ObjectiveTo retrospectively study the acute epileptic seizures of patients with anti-N-methyl-D-aspartate receptor (anti-NMDAR)and anti-leucine-rich glioma-inactivated 1(anti-LGI1)encephalitis. The characteristics and short-term prognosis provide reference for early clinical diagnosis and treatment.MethodsThe patients with anti-NMDAR and anti-LGI1 encephalitis who were admitted to the Department of Neurology of Sichuan Provincial People’s Hospital from January 2018 to June 2020 were continuously included. The general information, clinical manifestations, acute seizures and types of seizures were reviewed and analyzed.To evaluate the difference between the characteristics of two kinds of autoimmune encephalitis in the acute phase of seizures and the short-term prognosis.ResultsA total of 75 patients with anti-NMDAR encephalitis and anti-LGI1 encephalitis (41 males and 34 females) were included, of which average ages are(32.8±17.9)years, average courses are(1.8±1.1)months.59 and 16 are respectively positive for anti-NMDAR and anti-LGI1 antibodies, respectively. Of the 75 cases, 56 cases (74.7%) had seizures in the acute phase. Among the 56 cases of seizures, 38 cases (67.8%) were accompanied by disturbances of consciousness, 5 cases (8.9%) of autonomic dysfunction, and 24 cases of decreased oxygenation capacity. (42.9%) and 20 cases (35.7%) who were admitted to NICU, there was a significant statistical difference compared with the seizure-free group (P<0.05). The median age of anti-NMDAR encephalitis in the acute stage of seizures was 23 years, and that of anti-LGI1 encephalitis was 56.5 years (P<0.05). Anti-NMDAR encephalitis and anti-LGI1 encephalitis are common in the acute phase of epileptic seizures (55.9%vs.53.8%). Anti-NMDAR encephalitis has more frequent seizures and status epilepticus in the acute phase (P<0.05). After early and rational use of anti-epileptic drugs(AEDs) and immunotherapy and other symptomatic and supportive treatments, 70% of 56 patients were effectively controlled for seizure. Follow-up 3 months later, 18 patients (32.1%) stopped using anti-epileptic drugs (AEDs), While 30 patients (53.5%) continued to receive AEDs treatment, of which 25 patients (44.6%) had no seizures.ConclusionBoth anti-NMDAR encephalitis and anti-LGI1 encephalitis have a higher risk of seizures in the acute phase. Patients with seizures are more likely to have disturbances in consciousness, decreased oxygenation capacity, and higher rates of admission to NICU. Anti-NMDAR encephalitis is more common in young people around 30 years old, and anti-LGI1 encephalitis is more likely to develop around 60 years old. Patients with anti-NMDAR encephalitis are more likely to have abnormal electroencephalograms, have a longer average hospital stay, and are more likely to have recurrent seizures and status epilepticus in the acute phase. After timely diagnosis and intervention treatment, most patients' seizures can be well controlled. After the acute phase, AEDs can be withdrawed in one third of patients.
