Treatment of secondary progressive multiple sclerosis - Current recommendations and future prospects

Disease progression and advancing disability will supervene in the majority of multiple sclerosis patients who are followed over the long-term. This process can begin insidiously from the onset of the disease (primary progression) or after one or more clinical flares (secondary progression). The factors which lead to progression of disability are incompletely understood. The progressive forms of multiple sclerosis have been remarkably resistant to treatment. The legacy of heroic immunosuppression as a treatment for the disease progression has been modest indeed although there is some recent enthusiasm for immunosuppression with agents like mitoxantrone. In the last decade, the treatment of relapsing forms of multiple sclerosis has been revitalised by the interferons and glatiramer acetate. The robust treatment effect on the magnetic resonance imagine burden of the disease and the modest treatment effect in the suppression of clinical attacks have raised hopes that these agents might stall the disease in its progressive phase. Recent clinical trials with the interferons are indeed showing promise for modest clinical efficacy in patients selected for treatment on the basis of chronic progression. Given the weakness of the current treatment, the essence of disease management remains the handling of the complications of the disease. The management of bladder disturbances, spasticity, pain, depression, emotional lability, paroxysmal disorders, fatigue and heat intolerance, tremor and sexual dysfunction is reviewed.
