Objective:
Mitoxantrone (MX) is a potent immunosuppressant that is licensed as escalation therapy for the treatment of active multiple sclerosis (MS).
Methods:
In an open-label, retrospective analysis, we investigated effects of MX therapy on parameters of cognitive functions in patients with progressive MS and significant disability. Twenty patients received a total of 42 mg/m(2) MX in 4 cycles. Six patients who fulfilled the criteria for MX therapy, yet did not receive this treatment, served as controls. Before initiation of therapy and after a mean observation period of 24 months, neurological examination and a neuropsychological test battery were performed. Neuropsychological analyses comprised tests for cognitive flexibility as a part of executive functioning, and verbal as well as non-verbal tests for memory and attention. Additionally, intelligence and symptoms of depression were investigated.
Results:
While there was stability of EDSS over time, there were no differences in cognitive functions before and after MX treatment. In contrast, patients not receiving MX showed a worsening of verbal short term memory and cognitive flexibility over the same time period.
Conclusion:
In conclusion, this preliminary observational study points at stability of cognitive functions under MX therapy in patients with progressive multiple sclerosis.
