RESUMO
After years of low incidence, a large increase of new tuberculosis (TB) cases has been reported in Germany since 2015. New immunotherapies for the treatment of multiple sclerosis (MS) are associated with a reduced immune competence and a potential increased risk for infections. Most neurologists lack specific experiences with TB infections. This article summarizes specific recommendations for the diagnostics and treatment of TB under MS immunotherapies with a focus on the situation in Germany. Due to low case numbers and little experience with the risk of TB under the new immunotherapies, the clinical competence network for MS (KKNMS) consensus recommendations have a low grade of evidence.

The reversible potassium channel blocker 4-aminopyridine is effective in the treatment of numerous cerebellar dysfunctions, such as episodic ataxia type 2 and downbeat nystagmus syndrome. In 2011, its sustained release form, dalfampridine, was admitted in Europe for the treatment of walking difficulties in patients with multiple sclerosis (MS). Here we report the case of a 44-year old patient with a progressive MS whose upper limb tremor was markedly reduced under treatment with 4-aminopyridine, as documented in a Tremor Activities of Daily Living questionnaire and in the 9-Hole Peg test. Hand accelerations decreased in the left hand from 10.9 m/sec(2) to 2.2 m/sec(2) and in the right hand from 4.2 m/sec(2) to 0.9 m/sec(2). This case report indicates for the first time that 4-aminopyridine might be effective in the symptomatic treatment of tremor entities in patients with MS. The finding calls for further prospective studies to determine the usefulness of 4-aminopyridine or its sustained-release form dalfampridine in treating patients with tremor and MS.
