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.

Plasmacytoid dendritic cells are increased in cerebrospinal fluid of untreated patients during multiple sclerosis relapse.

The plasmacytoid dendritic cells (pDCs) express a high level of Toll-like receptor 9 (TLR-9), which recognizes viral DNA. Activated via TLR-9, pDCs also secrete large amounts of type I interferon which are involved either in stimulation or down regulation of immune response in multiple sclerosis (MS). In the present study, we determinate pDCs levels by flow cytometry in Cerebrospinal Fluid (CSF) and Peripheral Blood from MS patients in relapsing and in remitting phases of the disease, comparing with other non-inflammatory diseases (OND). We provide evidence that MS patients in relapse without any treatment have a significantly (p < 0.01) higher percentage of pDCs in CSF than do patients in remission or those with OND. No change in the percentage of pDCs was observed in the peripheral blood of any of these patients. The increase of pDCs in central nervous system during relapse may be explained either by a virus infection or a down regulatory process.
