Multiple Sclerosis Optic Neuritis Treatment with Blood Adsorption: Is It Effective?

Optic neuritis associated with multiple sclerosis (MS) and neuromyelitis optica (NMO) can cause significant visual impairment and requires prompt and effective treatment, especially during acute exacerbations. One of the therapeutic options available is blood adsorption, although it is not the most commonly used method. More traditional approaches such as corticosteroid pulse therapy, intravenous immunoglobulin (IVIG), and plasma exchange are typically considered first-line interventions.

Common Treatment Options for Acute Exacerbations

During the acute phase of optic neuritis related to MS or NMO, several treatment modalities are available depending on the severity and patient response. Methylprednisolone pulse therapy is often the initial treatment of choice. However, in patients who show a poor response to corticosteroids, plasma exchange may offer a viable alternative. Typically, a course of 3–5 sessions is recommended, with each session using approximately 2–3 liters of plasma. Most patients begin to show improvement after 1–2 sessions.

Plasma Exchange and Intravenous Immunoglobulin

In cases where plasma exchange is not accessible or feasible, IVIG therapy may be considered as an alternative. A standard regimen usually involves daily infusions over a 5-day period. IVIG can help modulate the immune response and may provide clinical benefits in selected patients, particularly those who cannot undergo plasma exchange due to logistical or medical constraints.

Combination Therapy for Autoimmune Comorbidities

For patients who have optic neuritis in conjunction with other autoimmune conditions, combination therapy may be more effective. Corticosteroids can be used alongside other immunosuppressive agents such as cyclophosphamide. This dual approach helps manage both the acute inflammation and the underlying autoimmune activity, potentially leading to better long-term outcomes.

Is Blood Adsorption a Viable Option?

Blood adsorption, while not a standard treatment for optic neuritis, is being explored in some clinical settings as an adjunct or alternative therapy. It works by removing harmful antibodies and inflammatory mediators from the bloodstream, potentially reducing the autoimmune attack on the optic nerve. However, more research is needed to establish its efficacy and optimal use in the context of MS-related optic neuritis.

In summary, while blood adsorption may hold promise as part of a broader treatment strategy, the current standard of care for optic neuritis in the context of multiple sclerosis or neuromyelitis optica includes corticosteroids, plasma exchange, and IVIG. Treatment should be tailored to the individual patient, taking into account disease severity, response to prior therapies, and the presence of comorbid autoimmune conditions.
