A pilot study of functional electrical stimulation cycling in progressive multiple sclerosis.

BACKGROUND: Functional electrical stimulation (FES) cycling is used by spinal cord injury patients to facilitate neurologic recovery and may also be useful for progressive MS patients. OBJECTIVE: To evaluate the safety and preliminary efficacy of home FES cycling in progressive MS and to explore how it changes cerebrospinal fluid (CSF) cytokine levels. METHODS: Five patients with primary or secondary progressive MS were given an FES cycle for six months. Main outcome measures were: Two Minute Walk Test, Timed 25-foot Walk, Timed Up and Go Test, leg strength, Expanded Disability Status Scale (EDSS) score, and Multiple Sclerosis Functional Composite (MSFC) score. Quality-of-life was measured using the Short-Form 36 (SF-36). Cytokines and growth factors were measured in the CSF before and after FES cycling. RESULTS: Improvements were seen in the Two Minute Walk Test, Timed 25-foot Walk, and Timed Up and Go tests. Strength improved in muscles stimulated by the FES cycle, but not in other muscles. No change was seen in the EDSS score, but the MSFC score improved. The physical and mental health subscores and the total SF-36 score improved. CONCLUSIONS: FES cycling was reasonably well tolerated by progressive MS patients and encouraging improvements were seen in walking and quality-of-life. Larger studies of FES cycling in progressive MS are indicated.

Quality care in transverse myelitis: a responsive protocol.

This study was conducted to aid in the development of a multidisciplinary care center for patients with transverse myelitis. We surveyed the parents of 20 children diagnosed with transverse myelitis between the ages of 0.5 and 21 years to understand their experiences in navigating the health care system. We analyzed acute care events and long-term follow-up in relation to patient satisfaction. Results showed satisfactory ratings in the vicinity of 50% in key areas such as the articulation of a treatment plan. A significant disparity was found in the patients' desire for specialty care and their ability to procure such care. In all, 90% of patients expressed a desire to consult with a psychiatrist, but only 25% were successful in making a visit, a 64% deficit; 70% of respondents also desired to see a gastroenterologist, with only 25% actually doing so, leaving a 43% gap. Recommendations and patient opinions regarding the creation of a collaborative care environment are noted. Research with a larger sample will further elucidate the needs in transverse myelitis patient care.

Reduction of disease activity and disability with high-dose cyclophosphamide in patients with aggressive multiple sclerosis.

OBJECTIVE: To explore the safety and effectiveness of high-dose cyclophosphamide (HiCy) without bone marrow transplantation in patients with aggressive multiple sclerosis (MS). DESIGN: A 2-year open-label trial of patients with aggressive relapsing-remitting multiple sclerosis (RRMS) given an immunoablative regimen of HiCy (50 mg/kg/d for 4 consecutive days) with no subsequent immunomodulatory therapy unless disease activity reappeared that required rescue therapy. SETTING: The Johns Hopkins University Multiple Sclerosis Center, Baltimore, Maryland. Patients A total of 21 patients with RRMS were screened for eligibility and 9 patients were enrolled in the trial. Patients were required to have 2 or more gadolinium-enhancing lesions on each of 2 pretreatment magnetic resonance imaging scans, at least 1 clinical exacerbation in the 12 months prior to HiCy treatment, or a sustained increase of 1.0 point or higher on the Expanded Disability Status Scale (EDSS) in the preceding year. Intervention Patients received 50 mg/kg/d of cyclophosphamide intravenously for 4 consecutive days, followed by 5 mug/kg/d of granulocyte colony-stimulating factor 6 days after completion of HiCy treatment, until the absolute neutrophil count exceeded 1.0 x 10(9) cells/L for 2 consecutive days. MAIN OUTCOME MEASURES: The primary outcome of the study was the safety and tolerability of HiCy in patients with RRMS. Secondary outcome measures included a change in gadolinium-enhancing lesions on magnetic resonance images and a change in disability measures (EDSS and Multiple Sclerosis Functional Composite). RESULTS: Nine patients were treated and followed up for a mean period of 23 months. Eight patients had failed conventional therapy and 1 was treatment naive. The median age at time of entry was 29 years (range, 20-47 years). All patients developed transient total or near-total pancytopenia as expected, followed by hematopoietic recovery in 10 to 17 days, stimulated by granulocyte colony-stimulating factor. There were no deaths or unexpected serious adverse events. There was a statistically significant reduction in disability (EDSS) at follow-up (mean [SD] decrease, 2.11 [1.97]; 39.4%; P = .02). The mean (SD) number of gadolinium-enhancing lesions on the 2 pretreatment scans were 6.5 (2.1) and 1.2 (2.3) at follow-up (81.4% reduction; P = .01). Two patients required rescue treatment with other immunomodulatory therapies during the study owing to MS exacerbations. CONCLUSION: Treatment with HiCy was safe and well tolerated in our patients with MS. Patients experienced a pronounced reduction in disease activity and disability after HiCy treatment. This immunoablative regimen of cyclophosphamide for patients with aggressive MS is worthy of further study and may be an alternative to bone marrow transplantation.
