AB0769 Clinical, laboratory, neuroimaging and treatment of primary versus secondary central nervous system vasculitis
2013
Background Primary central nervous system vasculitis (PCNSV) is an uncommon condition in which vascular inflammatory lesions are limited to the brain and spinal cord. Diagnostic criteria include a newly acquired neurological deficit that is unexplained by other processes and angiographic or central nervous system (CNS) biopsy features of vasculitis. In contrast secondary central nervous system vasculitis (SCNSV) is vascular inflammation in which CNS involvement is due to diverse causes. Objectives To investigate the clinical, laboratory, neuroimaging characteristics and treatment in Primary Central Nervous System Vasculitis (PCNSV) versus Secondary Central Nervous System Vasculitis (SCNSV). Methods We studied twenty female patients with central nervous system vasculitis (CNS) during a period of 3 years in a tertiary level center. The clinical manifestations, laboratory, neuroimaging diagnosis and treatment were analyzed. Patients were divided in PCNSV and SCNSV. Biopsy CNS was performed in 3 patients. Results We studied 10 PCNSV and 10 SCNSV patients: systemic lupus erythematous 5, systemic sclerosis (SSc) 4, Sjogren syndrome (SS) 1. Mean age in the PCNSV was 26±5 years and SCNSV 47±7years. Clinical manifestation in PCNSV versus SCNSV were: headache 90% vs 60% (NS), fatigue 80% versus 40% ( Conclusions PCNSV had lower frequency of motor deficit, as well as lower ANA’s, and hypocomplementemia in comparison with SCNSV; an increase of CSF proteins was observed in all patients. MRI showed more periventricular and subcortical hyperintense lesions in SCNSV than PCNCV. All patients responded successfully to treatment with steroids plus cyclophosphamide. Early recognition and treatment may reduce poor outcomes. References Salvarini C, Brown RD Jr, Hunder GG.
