Zhonghua Yi Xue Za Zhi. 2021 Jul 20;101(27):2170-2172. doi: 10.3760/cma.j.cn112137-20210219-00432.

ABSTRACT

This study reviewed the clinical data of patients who were hospitalized in the Department of Neurology of Henan Provincial People's Hospital from January 2017 to October 2020. A total of 46 patients with positive serum anti-CV2 antibody were included. The average age of the patients was (54±15) years old, with a male to female ratio of 1.88∶1. Twenty-six patients were diagnosed with paraneoplastic neurological syndrome (PNS). The most malignant tumors were thymoma, small cell lung cancer, and prostate cancer. The most common PNS included myasthenia gravis, subacute cerebellar degeneration, and subacute/chronic sensorimotor neuropathies. Twenty non-PNS patients exhibited subacute/old cerebral infarction, Parkinson's disease, Alzheimer's disease, and so on. Among them, brain magnetic resonance imaging (MRI) of 10 cases showed different degrees of white matter demyelination, some of which were accompanied by brain atrophy. The current study found that the positive predictive value of anti-CV2 antibody for the diagnosis of PNS was 56.5%, which was relatively weak. As an accompanying antibody, it may be a coincidence, and it may also be related to the involvement of family members in the pathological process of the diseases.
