Patients with selective IgA deficiency, the most common primary immunodeficiency, occasionally may undergo spontaneous recovery. In this paper we present three additional children whose IgA levels spontaneously returned to normal. All three presented with gastrointestinal symptoms, and one child also had frequent upper respiratory infections. We review other cases of spontaneous IgA deficiency, and the role of exogenous function in its etiology, and possible mechanisms of recovery.
