The Effectiveness of Thyroid Elastography in Evaluating Thyroiditis in Children with Type 1 Diabetes

Shear wave elastography can detect inflammation and fibrosis in the thyroid tissue. It can be used to evaluate Hashimoto's thyroiditis or in the assessment of thyroid diseases accompanying type 1 diabetes mellitus. Our aim was to examine whether there is a difference between the shear wave elastography scores as kilopascals of individuals with type 1 diabetes mellitus and healthy children, and the relationship between diabetes-related parameters and shear wave elastography scores.

A total of 77 type 1 diabetes mellitus children and 53 healthy controls were compared. Serum thyroid-stimulating hormone, free thyroxine, free tri-iodothyronine, antibodies against thyroid peroxidase and thyroglobulin, average of the last 2 control plasma glycosylated hemoglobin A1c, duration of diabetes and daily insulin dose in diabetic individuals, thyroiditis staging by ultrasound, and shear wave elastography scores were also recorded.

In terms of shear wave elastography scores, no significant difference was found between the healthy control group and the group with type 1 diabetes mellitus without Hashimoto's thyroiditis (7.9 ± 2.8 kPa vs. 8.4 ± 3.3 kPa, P = .772). The score of the group with type 1 diabetes mellitus accompanied by Hashimoto's thyroiditis (15.1 ± 6.6 kPa) was found to be higher than the group with type 1 diabetes mellitus without Hashimoto's thyroiditis and the healthy control group (P = .022 and P = .015, respectively).

This is the first study to compare children with type 1 diabetes mellitus and healthy controls in terms of shear wave elastography scores. We found that there was no significant difference between the shear wave elastography scores of children with type 1 diabetes mellitus without Hashimoto's thyroiditis compared to healthy controls.
