Abstract

The frequency of selective IgA deficiency is unknown in myasthenia gravis. We screened a series of 333 consecutive adult myasthenic patients for selective IgA deficiency and found only one patient with a selective IgA deficiency, which is not significantly different from the normal population. Organ-specific autoimmune diseases may differ from systemic autoimmune diseases concerning their frequency of association with selective IgA deficiency.
