[Triiodothyronine (T3) and thyroxine (T4) levels in patients with bronchial asthma]

In 212 patients with bronchial asthma and 115 healthy controls the serum levels of T4 and T3 were determined. In patients not treated with corticosteroids a statistically significant rise of T3 and fall of T4 were noted. These changes were non-significantly smaller in the patients with pronounced dyspnea . During long-term corticoid++ therapy a tendency was observed for normalization of these changes.
