Multiple Sclerosis
Multiple sclerosis (MS) is a chronic, autoimmune, degenerative disease affecting nearly 1 million adults in the United States. [1] Most patients present with symptoms between 20 and 40 years of age but have varying rates of disability impairment. [2]
There is currently no cure for MS. However, research has shown that autologous hematopoietic cell transplantation (HCT) is an efficient and safe treatment for active relapsing forms of MS to help prevent relapse, lesion-activity, and worsening disability while limiting unexpected adverse events. [2] In addition, patients with aggressive forms of MS may particularly benefit from transplant accompanied by high-dose immunotherapy. [3,4] Together, these treatments suppress the autoimmune inflammatory response and promote immune recovery.
The American Society for Transplantation and Cellular Therapy (ASTCT) has recommended autologous transplant be considered for “standard of care, clinical evidence available” treatment of refractory-relapsing MS. [2]
Advances
Recent research shows promising treatment options and provides recommendations for clinical decision-making for patients with aggressive forms of MS, including:

Referral Timing Guidelines
These guidelines highlight disease categories that include patients at risk for disease progression and who should be referred for a consultation for autologous or allogeneic transplantation.
Transplant Consultation Guidelines: Multiple Sclerosis
- After MS relapse, with ≥ 2 relapse episodes in past 3 years, while on disease modifying therapy
- Refer patient prior to progression of severe disability: patient must be able to walk 100 meters (with unilateral assistance: cane, crutch or brace)
