In this 'double-blind', randomized, placebo-controlled phase II trial, we compared an altered peptide ligand of myelin basic protein with placebo, evaluating their safety and influence on magnetic resonance imaging in relapsing-remitting multiple sclerosis. A safety board suspended the trial because of hypersensitivity reactions in 9% of the patients. There were no increases in either clinical relapses or in new enhancing lesions in any patient, even those with hypersensitivity reactions. Secondary analysis of those patients completing the study showed that the volume and number of enhancing lesions were reduced at a dose of 5 mg. There was also a regulatory type 2 T helper-cell response to altered peptide ligand that cross-reacted with the native peptide.

Background: Sex related differences in the course and severity of multiple sclerosis (MS) could be mediated by the sex hormones. Objective: To investigate the relation between serum sex hormone concentrations and characteristics of tissue damage on conventional magnetic resonance imaging (MRI) in men and women suffering from relapsing-remitting MS. Results: Serum testosterone was significantly lower in women with MS than in controls. The lowest levels were found in women with a greater number of gadolinium enhancing lesions. A positive correlation was observed between testosterone concentrations and both tissue damage on MRI and clinical disability. In men, there was a positive correlation between oestradiol concentrations and brain damage. Conclusions:The hormone related modulation of pathological changes supports the hypothesis that sex hormones play a role in the inflammation, damage, and repair mechanisms typical of MS.

We studied the effect of Bacille Calmette-Guerin (BCG) vaccine as an immunomodulator in MS. According to the guidelines for clinical trials in MS, a single crossover, MRI-monitored trial was performed in 14 patients with relapsing-remitting MS. After treatment, MRI activity was significantly reduced. No major adverse effects were reported. Adjuvant therapy with BCG vaccine was safe and merits study in MS.

Variables assessable within the first year of treatment significantly influence relapse rate and disability progression in patients with RRMS treated with IFN beta. These findings may help clinicians to make decisions regarding therapy regimen over time, and highlight the need for a prognostic algorithm.

Arachnoid cysts associated with SDH are anatomically separate conditions whose neurological symptoms respond to surgical drainage of the CSDH alone.
