Clinical Characterization of Patients with Chronic Spontaneous Urticaria according to Anti-TPO IgE Levels

Figure 1

Groups of patients according to anti-TPO IgE level. Patients were evaluated during a period of clinical control (UAS 0) and two periods of urticaria exacerbation (). Thirty patients had (+) anti-TPO IgE during the baseline period and 13 additional patients ( 43) during exacerbations (a). The number of patients according to the levels of anti-TPO in each period (baseline and two exacerbations periods) is presented in (b). At least two weeks was waited among the two exacerbation serum samples. OD: optical density.
