Background and purpose: Chronic inflammatory demyelinating polyneuropathy (CIDP) and multifocal motor neuropathy (MMN) are rare autoimmune diseases. Guidelines were published in 2010 for their diagnosis and treatment. In France, intravenous immunoglobulins (IVIGs) are mainly used for the first-line treatment. The burden of healthcare costs is often underlined but rarely studied. The aim of this survey was to compare to guidelines, the daily practice of French neurologists with IVIGs for CIDP and MMN treatment.
Methods: This was a retrospective observational study consisting of an online questionnaire performed between March and May 2014. A total of 49 questionnaires were included, a quarter of which were from neurologists working in neuromuscular reference centers (NRCs).
Results: A total of 182 patient case reports were studied. Patients were referred to an NRC for initial diagnosis in approximately 30% of cases in CIDP and 50% of cases in MMN. The initial management of IVIG (frequency, dose and duration) was not different between NRCs and non-NRCs. Guidelines were followed and neurologists were relatively at ease in diagnosing and treating patients.
Conclusions: This was the first national study to describe the implementation of the European Federation of Neurological Sciences/Peripheral Nerve Society guidelines in the daily management of IVIGs in patients with MMN and CIDP in France. Efforts are needed to improve long-term tailored treatment and home treatment to reduce economic costs.
