Figure 2From: The prevalence and identity of Chlamydia -specific IgE in children with asthma and other chronic respiratory symptomsPresence 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 thatwas higher than their C. pneumoniae-negative counterparts. Horizontal dark bars represent the average IgE level and each shape in the respectivecolumns represents a single patient.Back to article page
