Clinical correlation of 2D shear wave elastography findings in children with type 1 diabetes mellitus without autoimmune thyroiditis.

OBJECTIVES: The aim of study was to evaluate the 2D shear wave sonoelastography (SWE) findings of the thyroid gland in children with type 1 diabetes mellitus (T1DM) with normal gray-scale findings and without thyroid autoimmunity (AIT) and obtain data that will be useful for the early detection of glandular involvement.

METHODS: The study included 46 T1DM patients (mean age: 11.28 ± 3.3 years) and 46 healthy children (mean age: 12.01 ± 3.8 years) as the control group. The thyroid gland mean elasticity value was obtained as kPa and compared in groups. A correlation was investigated between elasticity values and age at diabetes, serum free T4, thyroid stimulating hormone (TSH), anti-thyroglobulin, anti-tissue peroxidase, and hemoglobin A1c values.

RESULTS: No difference was found between T1DM patients and the control group in the thyroid 2D SWE evaluation (the median kPa value: 17.1 (10.2) in the study group and 16.8 (7.0) in the control group) (p=0.15). No significant correlation was found between 2D SWE kPa values and age at diagnosis, serum free T4, TSH, anti-thyroglobulin, anti-tissue peroxidase, and hemoglobin A1c levels in T1DM patients.

CONCLUSIONS: Our study showed that the elasticity of the thyroid gland in T1DM patients without AIT was not affected differently from that of the normal population. If 2D SWE is used in routine follow-up in T1DM patients before the development of AIT, we think that it will be useful in the early detection of thyroid gland affections and AIT, and long-term comprehensive studies in this direction will contribute to the literature.
