Multiple sclerosis : clinical and laboratory research
-
To estimate the incidence and severity of nocebo responses in trials of symptomatic treatments (STs) and disease-modifying treatments (DMTs) for multiple sclerosis (MS). ⋯ Nocebo responses in MS trials are substantial and appear to have increased significantly in recent years with important implications for both trial design and clinical practice. Furthermore, nocebo responses exhibit an association with medication and trial-related factors.

Randomized Controlled Trial
Simvastatin treatment in patients with relapsing-remitting multiple sclerosis receiving interferon beta 1a: a double-blind randomized controlled trial.
This study was conducted to evaluate the effect of simvastatin (40 mg/day) as an adjuvant therapy to interferon beta (IFNb 1a, 30 microg once weekly) in relapsing-remitting multiple sclerosis patients, compared with placebo. ⋯ Our study supports the safety and efficacy of simvastatin as an add-on therapy to INFb 1a in patients with relapsing-remitting multiple sclerosis.

Meta Analysis
Meta-analysis of the efficacy and safety of Sativex (nabiximols), on spasticity in people with multiple sclerosis.
To determine the efficacy of Sativex (USAN: nabiximols) in the alleviation of spasticity in people with multiple sclerosis. ⋯ The meta-analysis demonstrates that nabiximols is well tolerated and reduces spasticity.

Psychiatric disturbances may occur at the onset of multiple sclerosis. However, information on their outcome is lacking. Our objective was to document the characteristics of psychiatric symptoms at presentation of multiple sclerosis and to define the long-term evolution of psychiatric disturbances in these patients. ⋯ Initial psychiatric disturbances improved later than neurological symptoms, or never fully recovered, regardless of the concomitant use of psychotropic medications. In most of the subjects psychiatric disturbances tended to remain over the follow-up period and at last visit, after a mean follow-up of 7.6 years (+/-2.3), 14 subjects (87%) had a supplementary diagnosis of psychiatric illness. Psychiatric symptoms at onset of multiple sclerosis may be indicators of possible maintenance of psychiatric morbidity in a sizeable proportion of patients.
