Objective:
To compare the clinical course of an unusual case of Miller-Fisher syndrome in systemic lupus erythematosus with therapeutic interventions, in particular with plasma exchanges.
Design:
The clinical state and laboratory and electrophysiologic parameters were controlled for over a year and related to therapeutic attempts with immunoglobulins, steroids, and plasma exchanges.
Setting:
Medical intensive care unit of a university hospital.
Patient:
A 17-year-old black female student with known systemic lupus erythematosus who developed ataxia, are flexia, and ophthalmoplegia (Miller-Fisher syndrome) and later became tetraplegic and required full mechanical ventilatory support.
Results:
High-dose immunoglobulin treatment combined with corticosteroid pulse therapy was not beneficial. However, plasma exchange (performed five times over a period of 4 months) was followed by a striking clinical improvement within hours after each plasma exchange.
Conclusions:
Plasma exchange appears to remove a yet unknown agent producing a distal motor nerve conduction block and is efficacious in severe neuropathy associated with Miller-Fisher syndrome in lupus erythematosus.
