The Significance of Ultrasound in Determining Whether SHPT Patients Are Sensitive to Calcitriol Treatment

Abstract EN

This study was to explore the significance of ultrasound in determining whether the patients with secondary hyperparathyroidism (SHPT) are sensitive to calcitriol treatment.

According to the decrease value of parathyroid hormone (PTH), 42 SHPT patients were divided into two groups: drug susceptible group and drug insusceptible group.

These 42 SHPT patients’ ultrasound images were retrospectively analyzed.

The morphology, size, number, blood flow, elastic modulus, and perfusion of the parathyroid glands were correlated with drug therapeutic outcome (oral calcitriol).

Most SHPT patients with drug susceptible showed volume <438.50 mm3 and number ≤2, with 0-1 structural and vascular patterns, associated with Relative Maximum Intensity (RIMAX) <1.59 and elastic modulus <18.8 kPa, whereas most SHPT patients with drug insusceptible showed volume ≥438.50 mm3 and number ≥3, with 2-3 structural and vascular patterns, associated with Relative Maximum Intensity (RIMAX) ≥1.59 and elastic modulus ≥18.8 kPa.

Therefore, ultrasonography in SHPT allows an accurate definition of the morphology, size, number, blood flow, elastic modulus, and perfusion of the parathyroid glands and is useful in determining whether SHPT patients are sensitive to calcitriol treatment.
