Background: the most important causes of thyroid diseases is autoimmunity in origin, and it seems that people with thyroid diseases present more signs of asthma.
Aim: This study aimed to study the frequency of autoimmune thyroid diseases among patients suffering from bronchial asthma.
Patients and Methods: 50 Egyptian children, with an age range of 2-12 years, 25 children of them were suffering from bronchial asthma and 25 healthy children as a control were included in this cross-sectional study. Asthmatic children were selected from the Allergy Clinic at Al-Hussain Hospital, Al-Azhar University. All participants were subjected to the following: full history taking, full clinical examination, and investigations including (Serum FT3, Serum FT4, Serum TSH, Serum anti TPO, Serum anti TG, Serum IgE & CBC for total Eosinophilic count).
Results: There were a high statically significant increase in Serum IgE level and total esinophilic count in cases compared to control with P value <0.01 but no statistical significant difference between different degrees of asthma. There were no statically significant difference in Serum thyroid hormones level and Serum auto-antibodies level in asthmatic patients when compared to controls (P >0.05).
Conclusion: This study show no significant thyroid affection in asthmatic children compared to studies done before.
