Background: Oligoclonal bands (OCB) are widely believed to be stable over time and rarely affected by disease-modifying treatment in MS. It is presently unknown how intrathecal immunoglobulin production and other cerebrospinal fluid (CSF) biomarkers are impacted by a highly efficacious procedure such as autologous haematopoietic stem cell transplantation (aHSCT). Objective: To describe the evolution of intrathecal immunoglobulin and neurofilament light (NFL) over time in MS patients treated with aHSCT. Methods: In this retrospective study, available data from previously made CSF investigations in 46 patients treated with aHSCT were analysed. Results: After a median follow-up time of 745 days, immunoglobulin G (IgG) OCB remained detectable in 74% of patients, the proportion of patients with a pathological IgG index went down from 70% to 46%, and the proportion of patients with a pathological NFL went down from 72% to 24%. In patients with follow-up time >1500 days, IgG OCB were detectable in 50% of patients, 14% had a pathological IgG index and none a pathological NFL. Conclusions: Intrathecal immunoglobulin production and NFL were lower after treatment with aHSCT, decreased over time and were normalised in a significant portion of patients. This challenges the notion that OCB are unaffected by therapeutic intervention in MS.

There are multiple sclerosis patients who suffer from an aggressive course of the disease with severe relapses and rapid accumulation of disability despite adequate treatment. In such cases high-dose immunoablation with autologous haematopoietic stem cell transplantation (ASCT) may be considered. Our objective was to report our experience with 26 multiple sclerosis patients treated with ASCT within the years 1998—2008. Twenty-six patients (Expanded Disability Status Scale 2.5—7.5 (median 6.0), multiple sclerosis duration 2—19 years (median 7)) with aggressive multiple sclerosis underwent autologous haematopoietic stem cell transplantation. Stem cells were mobilized by high-dose cyclophosphamide and granulocyte colony-stimulating factor, BEAM (carmustine, etoposide, cytarabine, melphalan) was used for immunoablation. Patients were evaluated at baseline and every six months post ASCT for adverse events and clinical outcome. Follow-up period was 11—132 months (median 66). Progression-free survival was calculated using the Kaplan— Meier method. At 3 and 6 years of follow-up 70.8% and 29.2% of patients respectively were free of progression. Patients with relapsing multiple sclerosis course, disease duration <5 years and age <35 years had a more favourable outcome. There was no death within 100 days after ASCT. We conclude that ASCT represents a viable and effective treatment option for aggressive multiple sclerosis.

Background: Over recent years numerous patients with severe forms of multiple sclerosis (MS) refractory to conventional therapies have been treated with intense immunosuppression followed by autologous haematopoietic stem cell transplantation (AHSCT). The clinical outcome and the toxicity of AHSCT can be diverse, depending on the various types of conditioning protocols and on the disease phase. Objectives: To report the Italian experience on all the consecutive patients with MS treated with AHSCT with an intermediate intensity conditioning regimen, named BEAM/ATG, in the period from 1996 to 2008. Methods: Clinical and magnetic resonance imaging outcomes of 74 patients were collected after a median follow-up period of 48.3 (range = 0.8–126) months. Results: Two patients (2.7%) died from transplant-related causes. After 5 years, 66% of patients remained stable or improved. Among patients with a follow-up longer than 1 year, eight out of 25 subjects with a relapsing–remitting course (31%) had a 6–12 months confirmed Expanded Disability Status Scale improvement > 1 point after AHSCT as compared with one out of 36 (3%) patients with a secondary progressive disease course ( p = 0.009). Among the 18 cases with a follow-up longer than 7 years, eight (44%) remained stable or had a sustained improvement while 10 (56%), after an initial period of stabilization or improvement with median duration of 3.5 years, showed a slow disability progression. Conclusions: This study shows that AHSCT with a BEAM/ATG conditioning regimen has a sustained effect in suppressing disease progression in aggressive MS cases unresponsive to conventional therapies. It can also cause a sustained clinical improvement, especially if treated subjects are still in the relapsing–remitting phase of the disease.
