Clinical Report: Initial hormonal, skeletal, and inflammatory responses following microwave ablation in hyperparathyroidism
Overview
This study investigates the short-term biochemical changes following microwave ablation in patients with hyperparathyroidism. Significant reductions in serum intact parathyroid hormone and calcium levels were observed, alongside early changes in bone turnover and inflammatory markers.
Background
Hyperparathyroidism (HPT) is characterized by excessive secretion of parathyroid hormone, leading to metabolic disturbances. Microwave ablation (MWA) has emerged as a minimally invasive treatment option for managing both primary and secondary HPT. Understanding the biochemical and inflammatory responses post-ablation is important.

Key Findings
iPTH and calcium levels decreased significantly by day 1 post-ablation (P < 0.001).
iPTH remained reduced at month 1 (P < 0.001), while calcium showed a slight rebound (P = 0.046).
Bone turnover marker PINP increased significantly at month 1 (P = 0.011).
FGF-23 levels declined over time (P = 0.015).
CRP levels peaked at day 1 and decreased by month 1 (P = 0.036).
No severe hypocalcemia was reported; transient hoarseness occurred in two patients.
Clinical Implications
The findings indicate that microwave ablation leads to rapid biochemical changes in patients with hyperparathyroidism.
Conclusion
Microwave ablation induces significant early biochemical and inflammatory changes in hyperparathyroidism.
A living clinical guideline outlines a treatment hierarchy for selected pharmacologic therapies in patients with obesity and selected patients with overweight.
