Different Fumaric Acid Esters Elicit Distinct Pharmacologic Responses.

Objective: To test the hypothesis that dimethyl fumarate (DMF, Tecfidera) elicits different biological changes from DMF combined with monoethyl fumarate (MEF) (Fumaderm, a psoriasis therapy), we investigated DMF and MEF in rodents and cynomolgus monkeys. Possible translatability of findings was explored with lymphocyte counts from a retrospective cohort of patients with MS.

Methods: In rodents, we evaluated pharmacokinetic and pharmacodynamic effects induced by DMF and MEF monotherapies or in combination (DMF/MEF).

Hereditary defect of cobalamin metabolism with adolescence onset resembling multiple sclerosis: 41-year follow up in two cases.

The cblC defect is the most common inborn error of cobalamin (Cbl) metabolism. Clinical severity and presentation of the cblC defect ranges from death to mild disability. Only 71 cases of late-onset cblC defect have been described in the literature.

Breakthrough treatment with bortezomib for a patient with anti-NMDAR encephalitis.

After its discovery, anti-N-methyl-d-aspartate receptor encephalitis is now an established neuroinflammatory disorder, for which various immune-suppressive strategies have been successfully proposed. The most commonly applied therapy includes high dose cortico-steroids, as well as plasma exchange procedures (PLEX), and subsequently either oral immunosuppressants, such as azathioprine or B-cell depletion by the anti- CD20 monoclonal antibody rituximab. However, in rare cases we are faced with patients who do not respond to either oral immunosuppressants, or rituximab.

Detection of JC virus archetype in cerebrospinal fluid in a MS patient with dimethylfumarate treatment without lymphopenia or signs of PML.

We report a 76-year-old MS patient, treated with DMF for 3 years. Lymphocytes never showed values below 1240/µl. CSF analysis revealed 1,988,880 copies/ml of JCV-DNA, JCV-DNA was detectable in serum and anti-JCV-antibody in CSF and serum were highly positive.

Recurrent trimethoprim-sulfamethoxazole-induced aseptic meningitis with associated ampicillin-induced myoclonic twitches .

Objective: To report a case of recurrent trimethoprim-sulfamethoxazole-induced aseptic meningitis with associated ampicillin-induced myoclonic twitches.

Materials And Methods: The patient was investigated using cerebral computed tomography, magnetic resonance imaging, cerebrospinal fluid examination, and electroencephalography. Written informed consent was obtained from the patient for access to clinical files for research purposes and publication.

Hypoechogenicity of brainstem raphe nuclei is associated with increased attack frequency in episodic migraine.

Introduction: Reduced echogenicity of the brainstem raphe nuclei (BRN) was demonstrated in major depression, possibly indicating serotonergic dysfunction. Postulating that migraine may constitute a "chronic low serotonin syndrome," we aimed to evaluate the echogenicity of midbrain structures, including serotonergic BRN in episodic migraine.

Methods: Transcranial sonography was performed in 39 patients with episodic migraine (median age 35, interquartile range (IQR): 27-47 years; 27 women) and 35 controls (median age 31, IQR: 29-47 years; 19 women).

Echogenicity of basal ganglia structures in different Huntington's disease phenotypes.

In Huntington's disease (HD), a neurodegenerative-inherited disease, chorea as the typical kind of movement disorder is described. Beside chorea, however, all other kinds of movement disturbances, such as bradykinesia, dystonia, tremor or myoclonus can occur. Aim of the current study was to investigate alterations in the echogenicity of basal ganglia structures in different Huntington's disease phenotypes.

Fumarate treatment in progressive forms of multiple sclerosis: first results of a single-center observational study.

Objectives: Therapeutic options in progressive forms of multiple sclerosis (MS) are still limited. Dimethyl fumarate (DMF) has immunomodulatory properties but may also exert antioxidative cytoprotective effects. Hence, it may be a therapeutic option for progressive MS.
