The clinical and serological characteristics of 86 patients with systemic lupus erythematosus (SLE) and central nervous system (CNS) disease were studied. They had a significantly high incidence of cardiac murmur, abnormal electrocardiographic and cerebral spinal fluid (CSF) findings, hypohemoglobinemia and hypoprotenemia as compared with 242 SLE patients without CNS disease.
In addition, the incidence of antibodies to asialo GM
1, Sm and proliferating cell nuclear antigen (PCNA) was higher in those patients with CNS.
The 86 SLE patients with CNS disease were divided into three groups : the first comprised patients with neurologic symptoms, seizures, cerebrovascular disesase (CVD), cerebral nervous disease, transverse myelopathy and so on ; the second, covered patients with psychosis (PS), and the third, patients with neuropsychiatric symptoms, seizure+PS, CVD+PS, and other neurological symptom +PS. The characteristics of these groups were studied.
The first group showed a high incidence of abnormal findings of the ocular fundus and a lower CSF sugar level. No particular serological differences among these three group were observed. But it was suggested that anti-asialo GM
1 antibody was related to CVD and the prognosis of patients with CVD was poor. Neuropathological manifestations were also studied in each group. The perivascular infiltrates of lymphocytes were observed in patients with seizures, but true arteritis of cerebral vessels was not found.
Therapeutic analysis were also performed. Regardless of the dosage of prednisolone, the prognosis of patients with CVD was poor. Pulse therapy (methylprednisolone 1000mg/day x three days) was effective for the patients with transverse myelopathy.
