Promising Emerging Therapies for Multiple Sclerosis

Therapeutic approaches to disease modifying therapy for multiple sclerosis in adults: an Australian and New Zealand perspective: part 1 historical and established therapies. MS Neurology Group of the Australian and New Zealand Association of Neurologists

Multiple sclerosis (MS) is a potentially life-changing immune mediated disease of the central nervous system. Until recently, treatment has been largely confined to acute treatment of relapses, symptomatic therapies and rehabilitation. Through persistent efforts of dedicated physicians and scientists around the globe for 160 years, a number of therapies that have an impact on the long term outcome of the disease have emerged over the past 20 years. In this three part series we review the practicalities, benefits and potential hazards of each of the currently available and emerging treatment options for MS. We pay particular attention to ways of abrogating the risks of these therapies and provide advice on the most appropriate indications for using individual therapies. In Part 1 we review the history of the development of MS therapies and its connection with the underlying immunobiology of the disease. The established therapies for MS are reviewed in detail and their current availability and indications in Australia and New Zealand are summarised. We examine the evidence to support their use in the treatment of MS.

Inhibition of selective adhesion molecules in treatment of inflammatory bowel disease

Lymphocyte infiltration into the intestinal tract in inflammatory bowel disease (IBD) is mediated by interaction between α4 integrin and its specific ligands. Development of monoclonal antibodies against α4 integrin allowed targeting of lymphocyte trafficking into the intestine as a novel therapeutic intervention. Natalizumab, vedolizumab, alicaforsen AJM300, rhuMAb β7, CCX282-B, and PF-00547,659 are few of monoclonal antibodies that have shown high promise in trials with the potential for more attractive benefit:risk ratio than currently available therapies. In this review, an attempt is made to underline the therapeutic potential and the safety of anti-adhesion molecule treatment in IBD.

Impact of electroacupuncture on quality of life for patients with Relapsing-Remitting Multiple Sclerosis under treatment with immunomodulators: a randomized study

Background

Multiple sclerosis (MS) is a complex autoimmune disease mediated by an immune response to central nervous system antigens. Modern immunomodulatory therapies, however, do not ameliorate many of the symptoms, such as pain and depression. Patients thus seek alternative treatments, such as acupuncture, although the benefits of such treatments have not been objectively evaluated. The present study was thus designed to evaluate the effect of the use of acupuncture in the alleviation of the symptoms of patients with MS.

Methods

Thirty-one patients with Relapsing-Remitting Multiple Sclerosis undergoing treatment with immunomodulators were randomly distributed into sex-stratified experimental and placebo groups in a patient- and evaluator-blind design; they received either true or sham electroacupuncture during regular visits to the doctor in the university hospital outpatient clinic. Standardized questionnaires were used to evaluate the effect of electroacupuncture on the quality of life of these patients. Initial and follow-up assessment included the evaluation of clinical status (Expanded Disability Status Scale), pain (Visual Analogue Scale) and quality of life (Functional Assessment of multiple Sclerosis) to ascertain the impact of electroacupuncture on the quality of life of these patients.

Results

Electroacupuncture improved various aspects of quality of life, including a reduction in pain and depression. The self-report scales were more sensitive to improvement than was the more objective clinical measure.

Conclusion

This paper provides evidence that electroacupuncture can significantly improve the quality of life of such patients. The results suggest that the routine use of a self-report scale evaluating quality of life should be included in regular clinical evaluations in order to detect changes more rapidly.

From injection therapies to natalizumab: views on the treatment of multiple sclerosis

Discoveries of the mechanisms that underlie the pathogenesis of multiple sclerosis have been acquired at an impressive rate over the last few decades and, as a consequence, a growing number of treatments are becoming available for this disease. This review first analyzes the experience from the early stages of the disease-modifying therapies, then, expanding on the concept of early treatment for improved outcomes, it focuses on natalizumab and its major complication, progressive multifocal leukoencephalopathy. We offer views on the risks associated with the use of natalizumab by underscoring the importance of the JC virus serology and by providing preliminary data on our experience with the extended interval dosing of natalizumab. This approach, which advocates individualized treatment plans, raises the question of the minimum effective natalizumab dose. Extended interval dosing suggests efficacy can be maintained while providing advantages of costs and convenience over regular monthly dosing. More data examining this strategy are necessary.
