Abstract
Objective To summarize the clinical features of three types of anti-metabotropic glutamate receptors(mGluRs)encephalitis,and to deepen the understanding of such diseases,enhance early diagnosis and treatment,and improve clinical prognosis.Methods PubMed,Web of Science,CNKI,and Wanfang Data were searched for Chinese and English articles on anti-mGluRs encephalitis published up to October 2023,and the clinical data of three subtypes of anti-mGluRs encephalitis were collected and analyzed.Results A total of 49 articles on anti-mGluRs encephalitis were obtained,with 40 cases of anti-mGluR1 encephalitis,3 cases of anti-mGluR2 encephalitis,and 43 cases of anti-mGluR5 encephalitis.Anti-mGluR1 encephalitis was more likely to occur in middle-aged women,with the main manifestation of cerebellar syndrome(95.0%,38/40);among the 40 patients with anti-mGluR1 encephalitis,22.5%(9/40)were found to have tumors,with lymphoma being the most common type of tumor(66.7%,6/9);52.8%(19/36)of the patients were found to have initial head MRI abnormalities,and about half of the patients were found to have cerebellar atrophy during follow-up.Anti-mGluR2 encephalitis had the main clinical manifestation of cerebellar syndrome,and tumor was only ob-served in 2 foreign patients.Anti-mGluR5 encephalitis easily affected young and middle-aged men,with the characteristic manifestation of limbic system symptoms,among which mental and behavioral disorders were the most common symptoms(74.4%,32/43);tumors were observed in 16.3%(7/43)of the patients,all of whom had Hodgkin's lymphoma.Conclusion The possibility of anti-mGluR1/2 encephalitis should be considered for patients with acute or subacute cer-ebellar ataxia accompanied by abnormal MRI cerebellar signals or atrophy,and the possibility of anti-mGluR5 encephalitis should be considered for patients with the initial symptoms of mental and behavioral disorders and cognitive changes.关键词
