Uitkomstmaten
Primaire uitkomstmaten
Primary outcome is maintaining the muscle strength after switching to subcutaneous immunoglobuline measured according to the Medical Research Counsil scale (MRC score). The MRC score will be measured during baseline visits (between 2 consecutive intravenous immunoglobuline treatment). After the switch to subcutaneous immunoglobuline MRC score is determined at 1, 2, 3, 4, 6 weeks and 3 4 and 6 months.
Achtergrond van het onderzoek
Multifocal motor neuropathy (MMN) is a rare immune mediated disorder characterized by slowly progressive, asymmetric, predominantly distal weakness of one or more limbs without sensory loss. Intravenous immunoglobuline (IVIg) is the first line treatment when disability is sufficiently severe to warrant treatment. An alternative route of immunoglobulin administration is subcutaneous immunoglobulin (SCIg), used in patients with immuno-deficiency syndromes. Our hypothesis is that SCIg therapy is as effective as IVIg therapy in maintaining muscle strength in patients with MMN. Patiens using IVIg will switch to SCIg and will be followed for at least 6 months in which muscle stregth, disability, side effects and immunoglobuline serum levels will be assessed.
Doel van het onderzoek
Subcutaneous immunoglobuline therapy is as effective as intravenous immunoglobuline therapy in maintaining muscle strength in patients with multifocal motor neuropathy
Onderzoeksproduct en/of interventie
Patients already treated with (different) intravenous immunoglobuline will switch to weekly subcutaneous immunoglobuline (Gammaquin, Sanquin, registered in the Netherlands under RVG 16941). This treatment will be continued for 6 months. After reaching the end of the study patients are allowed to choose between both treatments which they will continue.
