La sclérose en plaques est une maladie chronique, récurrente et progressive a associé avec les lésions du système nerveux et est maintenant croit pour être une maladie incendiaire. En raison des divers signes et le cadre de symptômes et temps entre les assauts initiaux il est parti parfois non traité pendant des années. Un cours de traitement devrait être commencé aussitôt qu'un malade est diagnostiqué avec un régulier donne suite à des traitements comme nécessaire. Les traitements d'oxygène de Hyperbaric ont montré une réponse favorable surtout dans les malades avec moins d'étapes avancé de la maladie.

Hyperbaric Oxygen Therapy for Multiple Sclerosis Patients
Reports from four countries describing benefits from hyperbaric oxygen Therapy (HBOT) in the 1970's led to the
first controlled trial conducted at New York University which was published in the New England Journal of Medicine
in 1983. The outcome was very positive (p<0.0001),1 despite choosing chronic progressive or stable patients with a
minimum disease duration of over 11 years.
The patients were matched and randomly allocated to treatment or control groups and examinations were
conducted before, during and after a course of treatment by masked observers. The authors indicated that further
studies using longer follow-up periods were necessary as were studies of the use of oxygen treatment in patients
with acute symptoms. The second trial, published in the Lancet in 1985 also recruited chronic patients with disease
duration in excess of ten years. It demonstrated statistically significant improvement in bladder function. (p< 0.03)
(2) The final report of this study found that at the end of a year of follow-up there was less deterioration of
cerebellar function in the treated group.(3)
The improvement in bladder function after a course of twenty sessions generally lasted for six months. These
authors also suggested that further studies should be undertaken. In 1986 a London group published a preliminary
report in the British Medical Journal. (4) Positive effects were again reported for bladder function and several other
symptoms. In 1988 Oriani et al (5) used patients with a low disability score and compared 22 controls with 22
patients treated every week for a year. They detected an appreciable difference in outcome (p < 0.01) and
confirmed the effect using evoked potential measurements. In 1986 Pallotta et al 6 published a follow-up of 22
patients over 8 years. All received an initial course of 20 HBO treatments, and 11 were treated thereafter with 2
exposures every 20 days. The frequency of relapses decreased dramatically in the prolonged treatment group
whereas they gradually increased in the group which received only an initial course of treatment. Oxygen delivered
under hyperbaric conditions is the only agent to have resulted in improvement in patients with chronic progressive
and chronic stable MS.
The Multiple Sclerosis Treatment Centers, which are A UK Charity, provide HBO therapy in 62 Centers. Note that
the MS Society does not endorse any treatment for Multiple Sclerosis but "is not hostile to HBO and does not
regard it as dangerous or expensive". The outcome of treatment in 703 patients followed for 10 or more years has
been studied. Comparison of the results with published data on the natural history of MS shows a significant
reduction in the rate of deterioration which is related to the frequency of treatment (7). The need for continuation
therapy is now accepted as with the use of beta interferon. The possibility of preventing sclerosis by treatment
during acute attacks has still to be addressed. Lactate, a marker of oxygen deficiency, can be seen in acute MS
lesions using magnetic resonance spectroscopy. This shows the need for urgent administration of oxygen and
there is no substitute.
