Randomized Controlled Trial Multicenter Study Comparative Study
Intravenous immunoglobulin versus intravenous methylprednisolone for chronic inflammatory demyelinating polyradiculoneuropathy: a randomised controlled trial.
Intravenous immunoglobulin (IVIg) and corticosteroids are effective as initial treatment in patients with chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), but little is known about the comparative risk-benefit profile of their long-term use in this disease. We compared the efficacy and tolerability of 6-month therapy with IVIg versus that with intravenous methylprednisolone. ⋯ Kedrion.

Neuromyelitis optica is an inflammatory demyelinating disorder of the CNS. The discovery of circulating IgG1 antibodies against the astrocyte water channel protein aquaporin 4 (AQP4) and the evidence that AQP4-IgG is involved in the development of neuromyelitis optica revolutionised our understanding of the disease. ⋯ New drug candidates have emerged, such as aquaporumab (non-pathogenic antibody blocker of AQP4-IgG binding), sivelestat (neutrophil elastase inhibitor), and eculizumab (complement inhibitor). Despite rapid progress, randomised clinical trials to test new drugs will be challenging because of the small number of individuals with the disorder.

Diabetic peripheral neuropathy is a prevalent, disabling disorder. The most common manifestation is distal symmetrical polyneuropathy (DSP), but many patterns of nerve injury can occur. Currently, the only effective treatments are glucose control and pain management. ⋯ However, the lack of disease-modifying therapies for diabetic DSP makes the identification of new modifiable risk factors essential. Growing evidence supports an association between components of the metabolic syndrome, including prediabetes, and neuropathy. Studies are needed to further explore this association, which has implications for the development of new treatments for this common disorder.

Many of the available disability outcome measures used in clinical trials of multiple sclerosis are insensitive to change over time, inadequately validated, or insensitive to patient-perceived health status or quality of life. Increasing focus on therapies that slow or reverse disability progression makes it essential to refine existing measures or to develop new tools. Major changes to the expanded disability status scale should be avoided to prevent the loss of acceptance by regulators as a measure for primary outcomes in trials that provide substantial evidence of effectiveness. ⋯ Conversely, although substantial data support the multiple sclerosis functional composite as an alternative measure, changes to its component tests and scoring method are needed. Novel approaches, including the use of composite endpoints, patient-reported outcomes, and measurement of biomarkers, show promise as adjuncts to the current disability measures, but are insufficiently validated to serve as substitutes. A collaborative approach that involves academic experts, regulators, industry representitives, and funding agencies is needed to most effectively develop disability outcome measures.

Randomized Controlled Trial Comparative Study
Diagnosis and treatment of patients with stroke in a mobile stroke unit versus in hospital: a randomised controlled trial.
Only 2-5% of patients who have a stroke receive thrombolytic treatment, mainly because of delay in reaching the hospital. We aimed to assess the efficacy of a new approach of diagnosis and treatment starting at the emergency site, rather than after hospital arrival, in reducing delay in stroke therapy. ⋯ Ministry of Health of the Saarland, Germany, the Werner-Jackstädt Foundation, the Else-Kröner-Fresenius Foundation, and the Rettungsstiftung Saar.
