Insights
Two-dimensional shear wave elastography (2D SWE) did not reveal differences in thyroid gland elasticity in children with type 1 diabetes mellitus (T1DM) without thyroid autoimmunity. This suggests 2D SWE may aid in early detection of thyroid issues in T1DM patients before autoimmunity develops.
Area of Science:
- Pediatric Endocrinology
- Medical Imaging
- Rheumatology
Background:
- Type 1 diabetes mellitus (T1DM) can affect thyroid function.
- Early detection of thyroid involvement in T1DM is crucial.
- Thyroid autoimmunity (AIT) is common in T1DM patients.
Purpose of the Study:
- To evaluate thyroid gland elasticity using 2D shear wave sonoelastography (SWE) in children with T1DM.
- To assess T1DM patients without AIT and normal gray-scale ultrasound findings.
- To identify potential early markers of thyroid involvement in T1DM.
Main Methods:
- The study included 46 T1DM patients and 46 healthy controls.
- Thyroid gland mean elasticity was measured using 2D SWE (in kPa).
- Elasticity values were correlated with clinical and laboratory parameters.
Main Results:
- No significant difference in thyroid gland elasticity was found between T1DM patients and controls (p=0.15).
- 2D SWE values showed no significant correlation with age at diagnosis, thyroid hormones, or diabetes control (HbA1c).
- No correlation was observed with specific autoantibodies (anti-thyroglobulin, anti-tissue peroxidase).
Conclusions:
- Thyroid gland elasticity is not significantly altered in T1DM children without AIT.
- 2D SWE may serve as a valuable tool for early detection of thyroid affections in T1DM prior to AIT development.
- Further longitudinal studies are recommended to confirm the utility of 2D SWE in T1DM thyroid monitoring.
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.
