Presence of Chlamydia organisms is associated with higher levels of serum IgE. While the average total serum IgE levels in this patient cohort was not significantly elevated (138 IU/ml), IgE levels were significantly more elevated in patients who were either Chlamydia DNA positive or who had viable organisms as determined by culture. Patients with C. pneumoniae-specific IgE also had an average total IgE level that was higher than their C. pneumoniae-negative counterparts. Horizontal dark bars represent the average IgE level and each shape in the respective columns represents a single patient.
