Abstract
- Objective: To observe the effects of intravenous methylprednisolone pulse (IVMP) therapy on the recovery of visual acuity and its influencing factors in patients with the relapse of aquaporin (AQP) 4 antibody positive neuromyelitis optica related optic neuritis (NMO-ON). Methods: Retrospective case series. Forty-eight eyes of 35 patients diagnosed as NMO-ON in the Neuro-ophthalmology Clinic of Beijing Tongren Hospital from September 2012 to April 2018 were included in this research. All patients were AQP4 antibody seropositive, and had clinical manifestations of acute optic neuritis, with a history of optic neuritis treated with glucocorticoids effectively. They received the treatment of IVMP 500 mg/d or 1 000 mg/d for 3 to 5 days. The post-treatment and pre-treatment visual acuities were compared. Improving four lines or more was considered as markedly effective, improving two or three lines as effective, and improving one line or no change or a decline as no effect. The impacts of age, visual acuity at onset, relapse rate and dosage on the acute exacerbation of NMO-ON were analyzed. Mann-Whitney U test and Kruskal-Wallis test were used for statistical analysis. Results: Among the 35 patients, there were 2 males and 33 females, aged from 15 to 73 years (median, 36 years). In the 48 eyes of recurrence, the treatment was effective 41.7% (20/48), effective 20.8% (10/48), and ineffective 37.5% (18/48). The IVMP therapy was effective in 25 of 34 eyes with one recurrence and 5 of 14 eyes with two or more recurrences, and the difference was statistically significant ( Z= 2.315, P= 0.021). The efficacy in 13 eyes with preoperative visual acuity not lower than 0.05 (10/13) was better than 35 eyes with preoperative visual acuity lower than 0.05 (20/35), and the difference was statistically significant ( Z= 1.994, P= 0.046). Different ages and doses (1 000 mg/d and 500 mg/d) made no significant difference in the efficacy ( P =0.273,0.105). Conclusions: The IVMP therapy is effective for the NMO-ON relapse in patients who were AQP4 antibody seropositive. The effect of IVMP treatment at doses of 500 mg/d and 1 000 mg/d is similar. Furthermore, visual acuity less than 0.05 and more relapses reduce the efficacy in relapsed NMO-ON patients. (Chin J Ophthalmol, 2020, 56: 509-513) .
