title: [Double-blind treatment of 49 cases of chronic multiple sclerosis using hyperbaric oxygen].
abstract: Forty nine patients with a chronic form of multiple sclerosis (MS) [progressive or stable] were treated with hyperbaric oxygen (HO) in a double blind trial. Patients were divided in three groups: the first group (group I) received a course of 2.3 ATA HO with diazepam (5 mg); the second group (group II) received a course of 2 ATA HO; the third group (group III) was the control group. Each patient breathed an adapted gaseous mixture in high pressure. Each patient received 20 sessions of this procedure during 4 weeks. Patients were evaluated with clinical, neurophysiological and immunological parameters. Clinical examination consisted in the evaluation of the Kurtzke's Disability Status Scale (DSS) and Functional Status Scale (FSS). This evaluation was done in the week before the procedure, the week following the treatment, then in the third and sixth month. The neurophysiological study was a comparative analysis from the variations of visual, somesthesic and brain stem auditory potentials. The immunological study was the analysis of the lymphocyte populations (OKT4/OKT8 ratio). Each examination was carried out the week before, then the week following the procedure. We found no amelioration into three groups. Subjectively, some patients thought to be better, but this was true in the two treated groups (I, II) and in the control group (III). There was not an FSS significant variation. We also found no significant variation of evoked potentials and OKT4/OKT8 ratio. We observed some incidental effects of the treatment, particularly in group I, in which patients were treated with a higher pressure.(ABSTRACT TRUNCATED AT 250 WORDS)
