ABSTRACT
Objective To investigate serum uric acid (UA) levels and related clinical features in patients with high risk syndrome of neuromyelitis optica. Methods UA levels were measured in 51 patients with high risk syndrome of neuromyelitis optica including 34 with longitudinally extensive transverse myelitis (LETM) and 17 with optic neuritis (ON), 48 with neuromyelitis optica (NMO), 45 with other neurological diseases (OND) and 65 with healthy controls (HC). The disability severity was assessed by the expanded disability status scale (EDSS). Spinal lesions were viewed by MRI. Serum aquaporin-4(AQP4) antibody was tested in cell based immunofluorescence assay. Results Serum UA levels in LETM ( ( 189. 84 ±85. 65) μmol/L) and ON patients ( (222. 12 ±61.68) μmol/L) were significantly lower than that in OND ((315.90±71.36) μ mol/L) and HC ((291.05 ±76.64) μ mol/L) subjects (P<0.01). No difference was found between LETM, ON and NMO groups. UA levels were significantly lower in females ( ( 158.24 ±55.92), (187.00±47.52), (198.21 ±62.62), (274.51 ±70.66)and (243.26±60.65) μmol/L)than in males ( ( 262. 09 ± 101.63 ), ( 262. 45 ± 62. 13 ), ( 298.90 ± 74. 14 ), ( 355.37 ± 50. 30 ) and (340. 34 ±58. 23) μmol/L) in all groups (t=3. 183, 2.578, 4.356, 4.365 and 6.579, all P<0.05).UA levels in patients with high risk syndrome of NMO were not correlated with mono or relapse course,duration or status of serum AQP4 antibody. UA were negatively correlated with EDSS in patients with LETM (r= -0.714, P<0.01). Conclusion Lower serum UA levels were found in patients with high risk syndrome of NMO and related to more severe symptoms in LETM group.
