Positive aRP antibodies were found in 51% （91 of 179 total cases） of cases of lupus psychosis. There was an almost 3.5-fold increased odds of psychosis in aRP-positive patients （OR = 3.46, 95%CI： 1.97-6.09, P 〈 0.001）. The population attributable risk percentage was 36% for aRP antibodies.CONCLUSION： aRP antibodies are common in lupus psychosis, although the potential mechanism（s） underlying this association remain unclear. Given the overlap between the clinical presentation and risk factors for lupus psychosis and schizophrenia, further investigation of aRP antibodies in schizophrenia is warranted.展开更多

Disruption of the blood-brain barrier (BBB) is integral to the neuropathology of SLE. Recently the possibility has been reported that aforementioned autoantibodies in the circulation may be strongly associated with disruption of the BBB. Each of these mechanisms might contribute to the pathogenesis of focal NPSLE (for example, cerebrovascular disease, movement disorders, myelopathy, seizures and cranial neuropathy) or diffuse NPSLE (for example, acute confusional state, psychosis and cognitive dysfunction) to varying degrees. In this review we focus on how the aforementioned autoantibodies, the BBB, IC and cytokines as well as chemokines are associated with the appearance of NPSLE.展开更多
