The authors studied in vitro immune function as measured by lymphocytic proliferative response to mitogen stimulation in 36 patients with agoraphobia and panic attacks who were participating in a double-blind placebo-controlled psychopharmacological study of anxiety disorder. No significant difference in immune status was observed between panic patients and healthy controls.
